When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0049] The utility model proposes a battery discharge device, which comprises a discharge mechanism 50, a lifting mechanism 10 and a transmission mechanism 20, wherein a lower coupling 40 is arranged on the top of the discharge mechanism 50; the lifting mechanism 10 is arranged on one side of the discharge mechanism 50; the transmission mechanism 20 is arranged on the lifting mechanism 10, and an upper coupling 30 is arranged on the bottom of the transmission mechanism 20; the lifting mechanism 10 is used to drive the transmission mechanism 20 to descend and dock the upper coupling 30 with the lower coupling 40 during the first descent; after the upper coupling 30 is docked with the lower coupling 40, the lifting mechanism 10 is also used to drive the upper coupling 30 to be clamped with the lower coupling 40 during the second descent; after the upper coupling 30 is clamped with the lower coupling 40, the transmission mechanism 20 is used to drive the transmission mechanism 20 and the discharge mechanism 50 to rise and fall synchronously.

[0050] In one embodiment, please refer to Figure 1The discharge mechanism 50 has a circuit. Specifically, the discharge mechanism 50 includes a fixed frame 51, a movable frame 52 and a copper sheet 53. The movable frame 52 can be raised and lowered on the fixed frame 51. The lower coupling 40 is arranged on the top of the movable frame 52; the copper sheet 53 is arranged on the bottom of the movable frame 52.

[0051] The bottom of the fixed frame 51 has a space for placing batteries to be discharged. The circuit is electrically connected to the copper sheet 53. When the movable frame 52 descends, the copper sheet 53 is driven to descend and abut against the batteries at the bottom.

[0052] It is understandable that before use, the position of the copper sheet 53 can be adjusted through debugging so that the position of the copper sheet 53 is just above the battery motor, so that when the copper sheet 53 drops, the battery motor is connected to the circuit to achieve discharge.

[0053] In one embodiment, the movable frame 52 includes a first movable plate 521, a positioning rod 523 and a second movable plate 522, the first movable plate 521 is arranged at the top of the fixed frame 51, and the lower coupling 40 is arranged at the top of the first movable plate 521; the movable frame 52 has a positioning hole, one end of the positioning rod 523 is connected to the first movable plate 521, and the other end passes through the positioning hole and extends to the bottom of the fixed frame 51; the second movable plate 522 is arranged at the bottom of the fixed frame 51, and the second movable plate 522 is connected to the positioning rod 523.

[0054] The first movable plate 521 and the second movable plate 522 can both adopt a quadrilateral plate structure. The bottom surface of the second movable plate 522 provides sufficient installation space for the copper sheet 53. The sufficient installation space can meet the requirements of arbitrarily adjusting the installation position of the copper sheet 53 to adapt to batteries of different models and specifications, thereby improving compatibility.

[0055] The first movable plate 521 at the top is used to install the lower coupling 40 so that it can be connected to the transmission mechanism 20 at the top. The second movable plate 522 at the bottom is used to install the copper sheet 53 so that it can abut against the battery at the bottom. Through the split design, the second movable plate 522 can be removed more conveniently, so as to adjust the position of the copper sheet 53 thereon.

[0056] In addition, in order to ensure stability during the lifting process, a positioning rod 523 is connected between the first movable plate 521 and the second movable plate 522, and the positioning rod 523 passes through the positioning hole on the fixing frame 51. The aperture of the positioning hole is adapted to the outer diameter of the positioning rod 523, so as to avoid the position deviation of the positioning rod 523 during the lifting process, thereby indirectly keeping the positions of the first movable plate 521 and the second movable plate 522 fixed.

[0057] The number of positioning rods 523 can be set to one or more. When multiple positioning rods 523 are set, the multiple positioning rods 523 are set parallel to each other. The installation positions of the multiple positioning rods 523 are adjusted so that they are evenly laid on the surface of the second movable plate 522 of the first movable plate 521.

[0058] In one embodiment, the transmission mechanism 20 is located above the discharge mechanism 50. The upper coupling 30 is located at the bottom of the transmission mechanism 20, and the lower coupling 40 is located at the top of the discharge mechanism 50. When the lifting mechanism 10 drives the transmission mechanism 20 to descend, the upper coupling 30 is connected to the lower coupling 40.

[0059] For details, please refer to Figure 1 and Figure 2 The lifting mechanism 10 includes a bracket 11, a guide member 12 and a driving cylinder 13. The bracket 11 is arranged on one side of the discharge mechanism 50; the guide member 12 is arranged on the bracket 11, and the transmission mechanism 20 is arranged on the guide member 12; the driving cylinder 13 is arranged on the bracket 11, and the driving end of the driving cylinder 13 is connected to the transmission mechanism 20.

[0060] The transmission mechanism 20 is disposed on the bracket 11 and extends to the top of the discharge mechanism 50 .

[0061] A guide member 12 is provided between the bracket 11 and the transmission mechanism 20. When the lifting mechanism 10 drives the transmission mechanism 20 to move up and down, the transmission mechanism 20 moves on the guide mechanism. The guide mechanism is used to position the transmission mechanism 20 to prevent the position of the transmission mechanism 20 from shifting during the lifting and moving process, thereby improving the positioning accuracy between the upper coupling 30 and the lower coupling 40.

[0062] The guide member 12 may be a guide rail, and the transmission mechanism 20 is mounted on the guide rail so as to move along the length direction of the guide rail to achieve guiding and positioning of the transmission mechanism 20 .

[0063] In one embodiment, please refer to Figure 3 The transmission mechanism 20 includes a mounting frame 21, a driving motor 22, a rotating shaft 23 and an elastic member 24. The mounting frame 21 is arranged on the lifting mechanism 10; the driving motor 22 is arranged on the mounting frame 21; the rotating shaft 23 is connected to the output end of the driving motor 22; the elastic member 24 is connected to the rotating shaft 23 through a flat key 25, and the upper coupling 30 is connected to the elastic member 24.

[0064] The driving cylinder 13 is a double-stroke cylinder. The lower coupling 40 has a first slot and a second slot connected to the first slot. The mounting frame 21 is used to provide installation space and support force for various components. The mounting frame 21 is fixed on the guide member 12, and the driving end of the driving cylinder 13 is connected to the mounting frame 21 to drive the mounting frame 21 to move up and down on the guide member 12. When the mounting frame 21 moves up and down, it drives the driving motor 22, the rotating shaft 23, the elastic member 24 and other components to move up and down synchronously.

[0065] The first stroke of the driving cylinder 13 descends, and the upper coupling 30 fixed on the transmission mechanism 20 is pressed onto the lower coupling 40 on the discharge mechanism 50. At this time, the elastic member 24 is compressed, and the elastic member 24 can be a spring. The driving motor 22 drives the rotating shaft 23 to rotate slowly to a specific angle, so that the upper coupling 30 is pressed into the first slot of the lower coupling 40 by the pressure of the spring, and the driving motor 22 stops.

[0066] The driving cylinder 13 descends in the second stroke, so that the upper coupling 30 is completely pressed into the lower coupling 40, that is, the upper coupling 30 is located in the second clamping groove at this time.

[0067] The driving motor 22 includes a servo motor and a reducer. The flat key 25 relies on two side surfaces as working surfaces and transmits torque by squeezing the key and the side of the keyway. The driving cylinder 13 uses a two-stage double-stroke cylinder, which can reduce the compression stroke of the spring and make the flat key 25 better transmit torque. This structure uses the flexible structure of the spring to make the reducer in the driving motor 22 receive the spring force instead of the downward force of the driving cylinder 13, which better protects the reducer.

[0068] In one embodiment, please refer to Figure 2 The transmission mechanism 20 includes a radiation optical fiber 26 and a sensor wheel 27. The radiation optical fiber 26 is arranged on the mounting frame 21; the sensor wheel 27 is arranged on the rotating shaft 23, and the position of the sensor wheel 27 corresponds to the position of the radiation optical fiber 26. The sensor wheel 27 is electrically connected to the driving motor 22.

[0069] When the driving motor 22 drives the rotating shaft 23 to rotate slowly to a specific angle, the upper coupling 30 is pressed into the first slot of the lower coupling 40 by the pressure of the spring. The induction wheel 27 also rotates to a corresponding position and can be sensed by the corresponding optical fiber 26. The induction wheel 27 can be electrically connected to the driving motor 22 through, for example, a controller.

[0070] When the induction wheel 27 senses the reflected optical fiber 26, the induction wheel 27 sends a detection signal to the controller, and the controller controls the drive motor 22 to stop. The controller can also be electrically connected to the drive cylinder 13, and through logical control, when receiving the detection signal, it controls the drive cylinder 13 to descend for the second stroke.

[0071] After the driving cylinder 13 descends in the second stroke, a height difference is formed between the induction wheel 27 and the corresponding optical fiber 26. After the induction wheel 27 cannot sense the corresponding optical fiber 26, the controller controls the driving motor 22 to start rotating and drive the copper sheet 53 on the discharge mechanism 50 to move up and down.

[0072] By adopting the method of the radiating optical fiber 26 and the induction wheel 27, the overall automation degree of the battery discharge device is improved, the convenience during the operation is improved, the on-site operator is avoided from repeating the operation, and the work efficiency is improved.

[0073] The technical solution of the utility model adopts a segmented processing method, in which the lifting mechanism 10 is lowered twice to drive the transmission mechanism 20 to descend, firstly docking the upper coupling 30 with the lower coupling 40 at the docking position, and then driving them to be connected, thereby reducing the stress when the upper coupling 30 and the lower coupling 40 are connected, slowing down the loss of parts in the equipment and extending the service life.

[0074] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
