FIELD
[0001] Example embodiments of the present disclosure relate generally to the field of electrical
devices, and more particularly, to an operation assembly for dual power supply switching
and associated switching apparatus.
BACKGROUND
[0002] In some electric devices, to avoid device power failure caused by a power supply
breakdown, devices are typically equipped with two groups of independent power supply
sources, i.e., a common power supply and a standby power supply. These are managed
by a dual power supply operation assembly to select an appropriate power supply to
power the device.
[0003] However, for some devices with a large rated current, existing handle-type dual-power
supply operation assemblies require a large manual operating force, which causes inconvenience
for users to switch power supplies by using a switch device.
SUMMARY
[0004] In a first aspect of the present disclosure, an operation assembly for dual power
supply switching is provided. The operation assembly comprises: a housing; a lock
tongue adapted to swing between a first closing position and a second closing position;
a pair of closing mechanisms symmetrically arranged on two sides of the lock tongue,
and each closing mechanism comprising: a mounting shaft coupled to the housing and
adapted to slide on the housing along an action direction; a lever adapted to push
the lock tongue to swing towards the first closing position or the second closing
position, and comprising: a fulcrum rotatably coupled to the mounting shaft to enable
the lever to rotate around the mounting shaft; a first end arranged on one side of
the fulcrum close to the lock tongue, and adapted to push the lock tongue to rotate
to the first closing position or the second closing position during sliding of the
lever with the mounting shaft from an initial position to an action position along
the action direction; and a second end arranged at one side of the fulcrum away from
the lock tongue and adapted to be pushed to drive the lever to rotate around the fulcrum
in a first rotation direction to a avoidance position, so as to avoid swinging of
the lock tongue towards the first closing position or the second closing position;
and a compression spring arranged between the housing and the lever in a compressed
manner and at least pushing the lever to slide along the action direction.
[0005] In some embodiments, a direction of a pushing force of the compression spring to
the lever is deviated from the mounting shaft, so that the compression spring drives
the lever to rotate around the mounting shaft in a second rotation direction opposite
to the first rotation direction.
[0006] In some embodiments, the lever further comprises a limiting block, and wherein the
housing is provided with an accommodating hole for accommodating the limiting block,
and the accommodating hole comprises: a first wall configured to contact the limiting
block during rotation of the lever in the second rotational direction and limit the
rotation of the lever in the second rotational direction.
[0007] In some embodiments, the accommodating hole further comprises: a second wall arranged
on one side of the limiting block facing away from the first wall, and adapted to
contact the limiting block during rotation of the lever in the first rotation direction,
and limit continued rotation of the lever in the first rotation direction.
[0008] In some embodiments, the operation assembly further comprises: a pair of operation
mechanisms respectively coupled to the pair of closing mechanisms, and comprising:
a push rod slidably coupled to the housing, and adapted to contact the second end
of the lever when pressed down, and drive the lever to rotate around the mounting
shaft to the avoidance position.
[0009] In some embodiments, the operation mechanism further comprises: a reset tension spring
coupled between the housing and the push rod and providing a pulling force to the
push rod, so as to drive the push rod to move in a direction away from the second
end.
[0010] In some embodiments, the operation mechanism further comprises: a closing button
coupled to a panel side of the housing and adapted to be pressed to drive the push
rod to slide towards the first end.
[0011] In some embodiments, the operation assembly further comprises: a tripping transmission
assembly arranged on the housing and adapted to trigger a tripping component of the
operation assembly, so that the lock tongue swings to a tripping position between
the first closing position and the second closing position, wherein the tripping transmission
assembly comprises: an operation rod rotatably coupled to the housing and adapted
to be driven to rotate about a first axis and trigger the tripping component; and
at least one transmission member coupled to the housing and in contact with the operation
rod to drive the operation rod to rotate about the first axis.
[0012] In some embodiments, the at least one transmission member comprises a first transmission
member and a second transmission member respectively rotatably coupled to the housing,
one end of the first transmission member and one end of the second transmission member
abut against each other, so that during rotation of the first transmission member,
and the second transmission member rotates in an opposite direction and drives the
operation rod to rotate.
[0013] In some embodiments, the tripping transmission assembly further comprises: a reset
torsion spring arranged on the housing, with one end coupled to the first transmission
member, and the other end coupled to the second transmission member.
[0014] In some embodiments, the operation assembly further comprises: a tripping button
coupled to the panel side of the housing and is adapted to be pressed to push an end
of the first transmission member away from the second transmission and control the
rotation of the first transmission member.
[0015] In some embodiments, the operation assembly further comprises: a reset spring arranged
between a panel of the housing and the tripping button.
[0016] After the closing button is pressed, the closing button pushes the push rod to slide.
Further, the push rod drives a lever at a corresponding side to rotate, so that a
first end of the lever avoids a lock tongue. With regard to the lock tongue, due to
the avoidance of the lever on one side of the lock tongue, the lever on the other
side of the lock tongue pushes the lock tongue to swing to a closing position (e.
g. a first closing position or a second closing position), thereby realizing the switching
of the operation assembly to different power supply. By means of the method, a user
can control the closing of the operation assembly by press a button, thereby improving
the convenience of operation, and at the same time, also improving the convenience
of operation of the operation assembly.
[0017] In a second aspect of the present disclosure, a switching apparatus is provided.
The switching apparatus comprises an operation assembly provided according to the
first aspect of the present disclosure.

DETAILED DESCRIPTION
[0020] Embodiments of the present disclosure will be described in more detail below with
reference to the accompanying drawings. Although certain embodiments of the present
disclosure are shown in the accompanying drawings, it should be understood, that the
present disclosure may be implemented in various forms and should not be construed

[0022] In the description of embodiments of the present disclosure, the term "including"
and the like should be understood as open-ended including, that is, "including but
not limited to". The term "based on" should be read as "based at least in part on".
The term "one embodiment" or "the embodiment" should be read as "at least one embodiment".

[0023] As mentioned briefly above, existing dual power operation assemblies for high current
devices are mostly handle-type. These operation assemblies require significant operational
force, making it difficult for users to switch the handle to a desired state when
users use the operation assemblies. Additionally, due to a relatively large elastic
action force of the handle, when the handle is swung to a critical position, the handle
easily swings to a desired position quickly under the action of an elastic force inside
the operation assembly, which can easily cause user injury.
[0024] To solve or at least partially solve the described problems or other potential problems
existing in the conventional solution, embodiments of the present disclosure provide
an operation assembly for dual power supply switching and associated switching apparatus.
Closing and tripping of the operation assembly can be controlled by press a button.
A user can push a closing button, and the closing button pushes a push rod to slide.
Further, the push rod drives a lever at a corresponding side to rotate, so that a
first end of the lever avoids a lock tongue. With regard to the lock tongue, due to
the avoidance of the lever on one side of the lock tongue, the lever on the other
side of the lock tongue pushes the lock tongue to swing to a closing position (e.
g. a first closing position or a second closing position), thereby realizing the switching
of the operation assembly to different power supply. In this way, a user can control
the closing of the operation assembly by press a button, thereby improving the convenience
of operation, and at the same time, also improving the convenience of operation of
the operation assembly.
[0025] FIG. 1 illustrates an overall structure schematic view of an operation assembly for
dual power supply switching according to some embodiments of the present disclosure.
FIG. 2 illustrates an interior structural schematic view of the operation assembly
with a partial housing hidden according to some embodiments of the present disclosure.
As shown in FIGS. 1 and 2, the operation assembly generally comprises a housing 1,
a lock tongue 2 coupled to the housing 1, and a pair of closing mechanisms 3 respectively
arranged at two sides of the lock tongue 2. The lock tongue 2 can swing relative to
the housing 1 between a first closing position and a second closing position, such
that the operation assembly connects the electrical device to a different power supply.
For example, when the lock tongue 2 swings to the first closing position, the operation
assembly controls the electrical device to be connected to the common power supply
in the power supply source, and when the lock tongue 2 swings to the second closing
position, the operation assembly controls the electrical device to be connected to
the standby power supply in the power supply source, thereby realizing the switching
of the dual power supply by the operation assembly.
[0026] In some embodiments, the lock tongue 2 may also swing to a tripping position located
between the first closing position and the second closing position. If the lock tongue
2 swings to the tripping position, the operation assembly simultaneously disconnects
the connection with the two power supplies, thereby stopping supplying power to the
electric device.
[0027] The following describes in detail how the closing mechanism 3 controls the lock tongue
2 to swing from the tripping position to the first closing position or the second
tripping position. Since the pair of the switching mechanisms 3 are symmetrically
arranged on both sides of the lock tongue 2, the following description mainly explains
how the closing mechanism 3 on one side (e. g., the first side) acts. However, it
should be understood that, in embodiments of the present disclosure, the action principle
and action effect of the closing mechanism 3 on the other side (i.e., the second time
opposite to the first side) are also similar.
[0028] FIG. 3 illustrates a cross-sectional view of an interior structure of the operation
assembly according to some embodiments of the present disclosure. As shown in FIGS.
2 and 3, the closing mechanism 3 includes a mounting shaft 31 slidably coupled to
the housing 1, a compression spring 33 arranged between the mounting shaft 31 and
the housing 1, and a lever 32 rotatably coupled to the mounting shaft 31. In some
embodiments, the housing 1 is provided with a guide rail, and the mounting shaft 31
is disposed in the guide rail, so that the mounting shaft 31 can slide relative to
the housing 1 along the extending direction of the guide rail to approach or away
from the lock tongue 2.
[0029] The lever 32 comprises a fulcrum 321, a first end 322 arranged on the side of the
fulcrum 321 close to the lock tongue 2 and a second end 323 arranged on the side of
the fulcrum 321 away from the lock tongue 2. The fulcrum 321 of the lever 32 is aligned
with the axis of the mounting shaft 31, so that the lever 32 can rotate around the
axis of the mounting shaft 31. Specifically, in some embodiments, the lever 32 may
be sleeved on the mounting shaft 31, so that the lever 32 may rotate relative to the
mounting shaft 31.
[0030] The compression spring 33 is arranged between the lever 32 and the housing 1, and
the compression spring 33 is in a compressed state, so that the compression spring
33 can push the lever 32 and the mounting shaft 31 to slide in the action direction.
In some embodiments, the action direction can be a direction towards the lock tongue
2, for example, the action direction can be parallel to the arrangement direction
of the two closing mechanisms 3 or a predetermined included angle is reserved between
the arrangement direction of the two closing mechanisms 3.
[0031] As shown in FIG. 3, when the operation assembly is in the tripping position, the
two levers 32 in the two closing mechanisms 3 are respectively in respective initial
positions. The first ends 322 of the two levers 32 are respectively abutted against
opposite sides of the lock tongue 2, and currently, the lock tongue 2 is in a balanced
state due to the pushing force of the lever 32 on opposite sides (i.e., the elastic
force from the compression springs 33 on opposite sides).
[0032] FIG. 4 illustrates a schematic view of the operation assembly performing closing
switch according to some embodiments of the present disclosure. As shown in FIG. 4,
when the closing mechanism 3 is actuated, the second end 323 of the lever 32 of the
first side closing mechanism 3 is pushed. Thus, the lever 32 rotates around the fulcrum
321 (i.e., the axis of the mounting shaft 31) along the first rotation direction to
the avoidance position. In this case, the first end 322 of the lever 32 avoids the
rotation track of the lock tongue 2, and the lever 32 on the second side slides from
the initial position to the action position along the action direction under the action
of the corresponding compression spring 33, and pushes the lock tongue 2 to swing
towards the first side, and after the lock tongue 2 is pushed to a critical state,
the lock tongue 2 swings to a first closing position under the action of an attraction
force inside the operation assembly. Thus, the electric device is connected to the
corresponding power supply source.
[0033] Referring back to FIGS. 1 and 2, in some embodiments, the pushing force of the compression
spring 33 on the lever 32 is offset from the axis of the mounting shaft 31, Thus,
the pushing force of the spring may also cause the lever 32 to have at least a tendency
to rotate in a second rotation direction opposite to the first rotation direction.
Thus, when the operation assembly is in a tripping state, the levers 32 of the pair
of closing mechanisms 3 can be respectively held at two sides of the lock tongue 2,
and stably providing a pushing force to the lock tongue 2, so that the lock tongue
2 is maintained at the tripping position.
[0034] Referring back to FIGS. 1 and 2, in some embodiments, the lever 32 further comprises
a limiting block 34, the limiting block 34 can be disposed at any suitable position
on the lever 32, and correspondingly, the housing 1 is further provided with an accommodating
hole 11 for accommodating the limiting block 34. The limiting block 34 is arranged
in the accommodating hole 11 and is configured to limit the continued rotation of
the lever 32 when the lever 32 rotates to a predetermined position under the action
of the compression spring 33. Specifically, when the lever 32 is rotated to the initial
position in the second rotation direction under the action of the compression spring
33, the limiting block 34 abuts against the first wall of the accommodating hole 11,
thereby limiting the continued rotation of the lever 32 in the second rotation direction.
When the lever 32 is rotated to the avoidance position in the first rotation direction,
the position limiting block 34 abuts against the second wall of the accommodating
hole 11, thereby limiting the continued rotation of the lever 32 in the first rotation
direction.
[0035] FIG. 5 illustrates a schematic view of the operation mechanism of the operation assembly
according to some embodiments of the present disclosure. As shown in FIG. 5 and in
conjunction with FIG. 2, in some embodiments, the operation assembly further comprises
a pair of operation mechanisms 4, wherein the pair of operation mechanisms 4 are respectively
arranged at two sides of the lock tongue 2 and correspond to the pair of closing mechanisms
3 on a one-to-one basis. The operation mechanism 4 is used for pushing the second
end 323 of the lever 32 and driving the lever 32 to rotate along the first rotation
direction. The operation mechanism 4 comprises a push rod 41 slidably coupled to the
housing 1, in which one end of the push rod 41 is in contact with a second end 323
of the lever 32, and the other end faces towards an operating side of the operation
assembly (i.e., towards a panel side of the operation assembly). When the push rod
41 is pressed down, the push rod 41 pushes the second end 323 of the lever 32, and
makes the lever 32 rotate around the fulcrum 321 along the first rotation direction
to the avoidance position.
[0036] In some embodiments, the operation mechanism 4 further comprises a closing button
43 arranged on the operating side of the operation assembly, the closing button 43
is coupled to the housing 1 of the operation assembly, and the operation assembly
abuts against one side of the push rod 41 away from the lever 32, When the closing
button 43 is pressed by the user, the closing button 43 pushes the push rod 41 to
slide in the direction of the lever 32, The lever 32 is rotated about the mounting
shaft 31 in a first rotation direction to a avoidance position under the action of
the push rod 41. The lock tongue 2 is swung into a first (or second) closing position.
[0037] In some embodiments, the operation mechanism 4 further comprises a reset tension
spring 42 arranged between the push rod 41 and the housing 1, one end of the reset
tension spring 42 is coupled to the housing 1, and the other end is coupled to the
push rod 41, and the reset tension spring 42 is configured to provide a tension force
to the push rod 41, so that the push rod 41 at least has a tendency to slide away
from one side of the lever 32 (i.e., a side close to the corresponding closing button
43). By means of the reset tension spring 42, the push rod 41 can automatically return
under the action of the reset tension spring 42 after the lever 32 rotates, Furthermore,
the tension spring may enable the closing button 43 to be raised again, thereby facilitating
the next operation of the user.
[0038] In some embodiments, the closing button 43 may be coupled to the housing 1 in a snap-fit
manner. For example, an elastic sheet may be coupled to a side of the closing button
43 facing the housing 1, and a snap block may also be coupled to the elastic sheet.
When the closing button 43 is coupled to the housing 1, the elastic sheet is inserted
into the corresponding housing 1, and at the same time, the snap block is snap-fitted
with the housing 1 under the action of the elastic sheet, so that the closing button
43 is fixed on the housing 1.
[0039] FIG. 6 illustrates a schematic view of a tripping transmission assembly according
to some embodiments of the present disclosure. As shown in FIG. 6 and in conjunction
with FIGS. 3 and 4, it is mentioned above that the swinging position of the lock tongue
2 also includes a tripping position between the first and second closing positions.
Correspondingly, the operation assembly further comprises a tripping transmission
assembly 5, the tripping transmission assembly 5 being arranged on the housing 1 and
comprising an operation rod 51 and at least one transmission member. The operation
rod 51 is rotatably coupled to the housing 1 and is adapt to be driven by a transmission
member to rotate around a rotation axis to trigger a tripping component 6 of an operation
assembly. After the tripping component 6 of the operation assembly is triggered, an
internal mechanism of the apparatus will act, so that the lock tongue 2 swings from
a first closing position or a second closing position to a tripping position.
[0040] In some embodiments, the operation assembly further comprises a tripping button 7,
the transmission member being arranged between the operation rod 51 and the tripping
button 7, and adapted to be drive by the tripping button 7 during the tripping button
7 being pressed, and to transmit a movement to the operation rod 51 such that the
operation rod 51 rotates about an axis.
[0041] In some embodiments, the tripping button 7 may be coupled to the housing 1 in a snap-fit
manner. In other embodiments, a reset spring 71 may be further disposed between the
tripping button 7 and a panel of the housing 1. When the tripping button 7 is pressed
down, the tripping button 7 is compressed. So that after the depression force applied
by user on the tripping button 7 is released, the reset spring 71 pushes the tripping
button 7 to reset.
[0042] In some embodiments, the transmission members comprise a first transmission member
52 and a second transmission member 53 respectively rotatably coupled to the housing
1. The ends of the first and second transmission members 52, 53 abut against each
other. When the first transmission member 52 is rotated under the pressure of the
transfer button 7 being pressed, the second transmission member 53 is pushed to rotate
in the opposite direction, so that the end of the second transmission member 53 away
from the first transmission part 52 pushes the operation rod 51 to rotate.
[0043] FIG. 7 illustrates a schematic view of the tripping transmission assembly from another
perspective according to some embodiments of the present disclosure. As shown in FIG.
7, in some embodiments, the tripping transmission assembly 5 further comprises a reset
torsion spring 54 coupled to the housing 1 and having one end abutting against the
first transmission member 52. The other end abuts against the second transmission
member 53, and the reset spring 71 provides an elastic force to the first transmission
member 52 and the second transmission member 53, so that after the tripping action
is completed, the first transmission member 52 and the second transmission member
53 can be reset under the action of the reset torsion spring 54 to allow the second
transmission member 53 to maintain a predetermined interval with the operation rod
51, thereby reducing a situation in which the tripping member 6 is erroneously touched.
