BACKGROUND
1. Technical Field
[0001] The present invention relates to a replacement structure and, in particular, to an
electronic implement replacement structure in a modular design.
2. Related Art
[0002] Conventional road lighting equipments utilize a mercury lamp or a sodium lamp as
a light source which illuminates a wider illumination zone but consumes more power,
cannot be recycled, and therefore is not environmentally friendly. In recent years,
the technology of a light emitting diode (LED) is increasingly developed. The LED
has advantages such as high luminance, power-saving, environmental friendliness, a
long life span, so has been widely used for lamp lighting and then used for road lighting.
[0003] When a street lamp malfunctions, it has to be repaired immediately in order to protect
safety of passers-by. In general, a repairman has to use an elevated work platform
(such as a cherry picker) in order to replace or repair the street lamp. However,
most malfunction conditions of conventional street lamps are scenarios in which a
power supply device or a sensor controlling on-and-off of the LED street lamp is damaged
or malfunctioning. The repairman has to remove a lampshade of an LED street lamp,
and then replace a whole set of the lamp street structure. Therefore, such a maintenance
method not only wastes time but also increases maintenance costs.
[0004] There is already an electronic implement replacement structure in the market, in
which an outer thread disposed on a light source structure and an inner thread disposed
in the lampshade are screwed together to assemble the light source structure and the
lampshade. However, in practice, during the assembly process, it is not easy to make
the outer and inner threads cooperatively engaged, thus causing inconvenience in assembling
the light source structure and the lampshade.
[0005] In view of the foregoing, the inventor made various studies to improve the above-mentioned
problems to realize the improvements by inventing an electronic implement replacement
structure.
BRIEF SUMMARY
[0006] It is an object of the present invention to provide an electronic implement replacement
structure, in which assembling, disassembling and replacing can be achieved without
any tools.
[0007] Accordingly, the present invention provides an electronic implement replacement structure
including a housing body and an electronic module. The housing body has a base and
a connecting ring connected to the base. The connecting ring includes a plurality
of press portions and a plurality of notches spaced apart from one another and respectively
disposed between each two adjacent press portions. A guiding groove is formed on an
outer surface of each of the press portions. The electronic module is disposed on
the base and corresponding to the connecting ring. The electronic module includes
an electronic unit and a rotatable ring enclosing the electronic unit. An inner wall
of the rotatable ring has a sliding block correspondingly and rotatably engaged with
the guiding groove.
[0008] The present invention also has the following effects: after the electronic module
is in alignment with the base, it only requires inserting the electronic module into
the base and rotating the electronic module by a small angle, and then the assembly
can be achieved fast and stably. Therefore, even an ordinary consumer can finish assembling
or disassembling in a simple and efficient way. Furthermore, the preset invention
has a wide application field which including the street lamp structure but not limited
thereto. Moreover, in the electronic unit of the present invention, the LED lamp can
be replaced by a surveillance camera such as a CCD/CMOS camera, the electronic unit
can also include the surveillance camera and the LED lamp at the same time, and the
present invention is not limited to the street lamp structure.

DETAILED DESCRIPTION
[0010] Detailed descriptions and technical contents of the present invention are illustrated
below in conjunction with the accompany drawings. However, it is to be understood
that the descriptions and the accompany drawings disclosed herein are merely illustrative
and exemplary and not intended to limit the scope of the present invention.
[0011] Referring to Figs. 1 and 2, the present invention provides an electronic implement
replacement structure 100 which comprises a housing body 102 and an electronic module
300. The electronic module 300 herein is preferably a light emitting diode (LED) lamp.
If the electronic module 300 is the LED lamp, the housing body 102 further has a plurality
of radiating fins 104 around the electronic module 300, so as to conduct heat to outside
the housing body 102. However, in different embodiments, the electronic module may
also be a surveillance camera such as a charge coupled device (CCD) camera or a complementary
metal oxide semiconductor (CMOS) camera.
[0012] As shown in Fig. 2, the housing body 102 includes a base 110 and a connecting ring
120 connected to the base 110. The connecting ring 120 includes a plurality of press
portions 124 and a plurality of notches 122 spaced apart from one another and respectively
disposed between each two adjacent press portions 124. According to the present embodiment,
preferably the connecting ring 120 is ring-shaped, consists of plastic or metal, and
is fixed on the housing body 102 by screws (not illustrated), wherein each of the
notches 122 and the press portions 124 is equidistant from one another on the ring
shaped connecting ring 120. In another preferable embodiment, the connecting ring
120 can also be integrally formed with the housing body 102. According to the present
embodiment, the ring-shaped connecting ring 120 is divided into 6 parts by every notch
122 and press portion 124, and each part of the ring-shaped connecting ring 120 is
substantially 60 degrees (central angle). However, in different embodiments, the ring-shaped
connecting ring 120 can be divided into four parts by every notch 122 and press portion
124, and each part of the ring-shaped connecting ring 120 is substantially 90 degrees
(central angle).
[0013] It should be noted that, the connecting ring 120 of the present embodiment consists
of plastic or metal and is fixed to the periphery of the base 110 by screws or other
components. If the connecting ring 120 is damaged or malfunctions accidentally, the
connecting ring 120 can be detached and replaced fast, thus facilitating repairing
or assembling of the electronic module 300.
[0014] A guiding groove 126 is formed on an outer surface of each of the press portions
124. The guiding groove 126 is adjacent to each of the notches 122, the guiding groove
126 and a surface of the housing body 102 together include an inclined angle A. An
inclination direction of the inclined angle A is from away from a surface of the housing
body 102 gradually toward the surface of the housing body 102. That is to say, the
direction of the guiding groove 126 is inclined from upper right to bottom left. As
shown in Fig. 2, the notch 122 similarly has the inclined angle A, and thereby the
electronic module 300 is in alignment with the notch 122 and quickly guided into the
guiding groove 126. On the contrary, to disassemble the electronic module 300 from
the base 110, the notch 122 having the inclined angle A can successfully make the
electronic module 300 detach from the base 110 in a vertical direction. Thereby, the
assembly and disassembly operation can prevent damaging an electric signal connector
(like a conductive terminal 312 shown in Fig. 12) of the electronic module 300.
[0015] The electronic module 300 disposed on the base 110 and corresponding to the connecting
ring 120. The electronic module 300 includes an electronic unit 310 and a rotatable
ring 330 enclosing the electronic unit 310. In the embodiment shown in Fig. 2, the
electronic unit 310 is preferably the LED lamp, and its structure will be described
afterward. However, in the embodiment shown in Fig. 3, the electronic unit 310 can
be CCD, CMOS, or other suitable photosensitive elements. An inner wall of the rotatable
ring 330 has a sliding block 332 correspondingly and rotatably engaged with the guiding
groove 126.
[0016] Referring to Figs. 4 to 7, the electronic module 300 further includes a joining element
320 and an elastic positioning portion 322. The joining element 320 is hollow and
has some integrally-formed fastening portions 324 to engage corresponding recesses
317, so as to position and fix the joining element 320 on the electronic unit 310.
The joining element 320 has some hook portions 328 on the other lateral edge opposite
to the fastening portions 324. Each hook portion 328 hooks an inner edge of an open
hole of the rotatable ring 330, so as to restrict a movement of the rotatable ring
330 along an axial direction. The elastic positioning portion 322 elastically reciprocate
on a circular-arc-shaped surface of the joining element 320, which allows visual inspection
of the rotatable ring 330 to determine whether it is rotated to a locked state.
[0017] Referring to Fig. 4 and Fig. 6, an outer surface of the rotatable ring 330 further
forms a plurality of openings 334, and the elastic positioning portion 322 is disposed
corresponding to the opening 334. When the rotatable ring 330 rotates, the hook portion
328 restricts the movement of rotatable ring 330 along the axial direction, but does
not affect the rotation of the rotatable ring 330. Furthermore, when the rotatable
ring 330 rotates, the elastic positioning portion 322 moves from one of the openings
334 to engage adjacent or corresponding another one of the openings 334. The location
of each opening 334 is designed according to a rotation distance of the guiding groove
126 on the press portion 124, which is for example 90 degrees or 60 degrees and varies
according to requirements or designs.
[0018] Referring to Figs. 8 to 11, detailed descriptions are provided hereinafter to explain
how the electronic module 300 is assembled to the base 110. To assemble the electronic
module 300, at first the repairman makes the electronic module 300 be in alignment
with the base 110. In other words, each conductive terminal 312 of the electronic
unit 310 is inserted into a corresponding slot 112 of the base 110 in order to make
an electrical connection, as shown in Fig. 11. At this point, the sliding block 332
of the electronic module 300 enters into a corresponding one of the notches 122. When
the rotatable ring 330 rotates, the sliding block 332 slides along the guiding groove
126 and rotates by an angle B to make the electronic module 300 positioned on the
base 110 at last.
[0019] According to the embodiment shown in Figs. 8 and 10, an end surface of the guiding
groove 126 further has a protruding portion 128 for engagement with the sliding block
332, such that the electronic module 300 is engaged on the base 110. The angle B hereinbefore
is preferably 60 degrees. In other words, a central angle of each press portion 124
(guiding groove 126) on the connecting ring 120 is around 60 degrees. However, in
different embodiments, the angle B can be around 90 degrees, namely a central angle
of each press portion 124 on the connecting ring 120 is around 90 degrees. Since the
angle B required to fasten tightly is very small, even an ordinary consumer can assemble
the electronic module 300 to the base 110 fast and efficiently without any tools.
[0020] As clearly appears in Fig. 11, the electronic module 330 is the LED lamp. That is
to say, the electronic unit 310 of the electronic module 300 consists of the conductive
terminal 312, an LED 314, a plastic cup 316, lens 318, related circuits (not illustrated),
and other components. The related components belong to conventional techniques and
thus a repetitive description thereof is omitted herein.
[0021] Referring to Figs. 12 and 13, to disassemble the electronic module 300 from the base
110, the repairman rotates the rotatable ring 330 at first, to make the sliding block
332 of the rotatable ring 330 detached from the protruding portion 128 of the guiding
groove 126, until the sliding block 332 slides to the notch 122 of the connecting
ring 122 (i.e. rotating by the angle B). When the sliding block 332 of the rotatable
ring 330 gradually slides to the highest of the notch 122, owing to the design of
the inclined angle A of the notch 122, the electronic module 300 is gradually detached
from the base 110 in a vertical direction. Referring to Fig. 13, the conductive terminal
312 of the electronic module 300 is removed by the connecting ring 120 from the base
110 of the housing body 102. Finally, the conductive terminal 312 of the electronic
module 300 is entirely detached from the slot 112 of the base 110 to complete the
disassembly operation.
[0022] Therefore, to disassemble the electronic module 300, the angle B by which the rotatable
ring 330 rotate to disassemble the electronic module 300 is very small. Thus, the
repairman can disassemble the electronic module 300 from the base 110 fast and efficiently
without any tools, thereby preventing damaging the conductive terminals 312 of the
electronic module 300.
