DETAILED DESCRIPTION
[0015] Referring to Figures 1 and 2, an embodiment of the present disclosure provides an
automatic unloading and lifting mechanism, which includes a frame 100, a cargo box
300, a motor 400, and a transmission component 200 arranged at the frame 100. The
cargo box 300 is slidably arranged on the transmission component 200, the transmission
component 200 is configured to drive the cargo box 300 to move up and down, and the
motor 400 is connected to the transmission component 200. The cargo box 300 is provided
with a delivery port at a top of the cargo box 300, a discharge port at a front end
of the cargo box 300, a bottom plate arranged to be inclined at the front end so that
cargo in the cargo box 300 slides toward the discharge port, and a turning plate 310
hinged with and configured for blocking the discharge port of the cargo box 300. The
frame 100 is provided with a supporting column 500 for supporting the turning plate
310 to block the discharge port.
[0016] In this embodiment, the supporting column 500 is used to support the turning plate
310. When the cargo box 300 is at a position within the height range of the supporting
column 500, the supporting column 500 supports the turning plate 310, and the turning
plate 310 blocks the discharge port of the cargo box 300. When the cargo box 300 is
at a position that exceeds the height range of the supporting column 500, the turning
plate 310 is no longer supported by the supporting column 500, so that the turning
plate 310 will drop and no longer block the discharge port. Since the bottom plate
of the cargo box 300 is inclined, the cargo is automatically unloaded by falling from
the discharge port. The automatic unloading and lifting mechanism has the advantages
of simple structure, convenient installation and low cost, and is suitable for automatic
lifting and unloading of small projects.
[0017] In another embodiment, a lower end of the discharge port of the cargo box 300 is
hinged with a lower end of the turning plate 310, and the turning plate 310 blocks
the discharge port by turning upwardly, and forms, together with the bottom plate
of the cargo box 300, a slideway for unloading and sliding of the cargo by turning
downwardly.
[0018] In this embodiment, when supported by the supporting column, the turning plate 310
turns upward to block the discharge port and prevent the cargo from pouring out; when
not supported by the supporting column, the turning plate 310 naturally turns down
and forms a slideway with the bottom plate, and the cargo are automatically unloaded
along the inclined slideway under gravity. No additional power is needed during the
unloading process, thus saving cost of energy.
[0019] In addition, a pulley 510 is arranged at a top of the supporting column 500. The
pulley 510 makes the opening and closing of the turning plate 310 more steady and
smooth. With this design, the automatic unloading of the cargo during the ascent and
descent of the cargo frame 300 is completed.
[0020] In another embodiment, a first Hall sensor 610 is provided at a top of the transmission
component 200, and a second Hall sensor 620 is provided at a bottom of the transmission
component 200; the first Hall sensor 610 and the second Hall sensor 620 are located
at a same side; a magnet 320 is provided on the cargo box 300 at the same side as
the first Hall sensor 610; the first Hall sensor 610 and the second Hall sensor 620
are respectively connected to the motor 400; a weight sensor for detecting whether
there is cargo in the cargo box 300 is arranged at the cargo box 300, and the weight
sensor is connected to the motor 400.
[0021] The Hall sensor is a magnetic field sensor made according to the principle of the
Hall effect. According to the Hall effect, the Hall voltage changes with the strength
of the magnetic field, the stronger the magnetic field, the higher the voltage, the
weaker the magnetic field, the lower the voltage. The Hall voltage is very small,
usually is only a few millivolts, but after being amplified by the amplifier in the
integrated circuit, the voltage can be amplified enough for outputting a greater signal.
To make the integrated circuit of the Hall sensor play a role of sensing, the magnetic
induction intensity needs to be changed by a mechanical method.
[0022] In this embodiment, when the cargo box 300 is full of cargo, the weight thereof will
increase and the weight sensor will send a signal to the controller of the motor 400,
the motor 400 is controlled to rotate by the controller, thus drive the transmission
component 200 to move, and so that the cargo box 300 will rise. When the cargo box
300 rises to a certain height, the magnet 320 of the cargo box 300 generates an induced
magnetic field sensed by the first Hall sensor 610, and the first Hall sensor 610
sends a signal to the motor 400 for stopping the motor 400. When the unloading of
the cargo box 300 is completed, the weight thereof will reduce, the weight sensor
will sends a signal to the motor 400, and the motor 400 is controlled to rotate reversely,
so that the cargo box 300 is lowered. When the cargo box 300 descends to a certain
height, the magnet 320 of the cargo box 300 generates an induced magnetic field sensed
by and the second Hall sensor 620, and the second Hall sensor 620 sends a signal to
the motor 400 for stopping the motor 400.

at a top of the frame 100. Transmission between the first transmission shaft 210 and
the second transmission shaft 220 is realized through a transmission belt 230. The
transmission component 200 further includes a smooth shaft 240, and a slider 250 is
provided on the smooth shaft 240. The slider 250 is slidably connected to the smooth
shaft 240 and fixedly connected to the cargo box 300. The slider 250 is linked with
the transmission belt 230 through a clamping plate 260. The transmission belt 230
may be any one of a belt or a rotating chain.
[0024] In this embodiment, the motor 400 drives the first transmission shaft 210 to rotate.
The transmission belt 230 on the first transmission shaft 210 moves the cargo box
300 vertically along the direction of the smooth shaft 240 through the clamping plate
260 and the slider 250 to complete the action of lifting.
[0025] In another embodiment, an automatic unloading and lifting mechanism includes a frame
