Description

[Technical field]

[0001] The present invention belongs to the technical field of charging cabinets, and in particular relates to a locking and unlocking structure for preventing shared items from accidentally popping out. [Background technology]

[0002] Shared item cabinets, including shared charging cabinets, are intelligent devices placed in business premises. Users can scan QR codes through WeChat, Alipay or specific apps to rent shared items or charging equipment, self-service billing and payment, self-service collection and refund of deposits, etc., which can achieve self-service and intelligence throughout the process. Common shared item cabinets include item storage cabinets, shared charging cabinets such as power bank shared charging cabinets, and shared charging cabinets generally include cabinet bodies, shared cabinet compartments, code scanning units, communication units, shared items, charging lines, etc. Common shared items include power banks. The shared cabinet compartment is installed on the cabinet body, and the shared items inserted inside can be stored and charged.

[0003] At present, when shared items are inserted into or removed from a shared cabinet, the shared items cannot be smoothly switched between the locked and unlocked states. At the same time, elastic pins are used to position the shared items and the shared cabinet. In the locked state, if the shared cabinet is impacted or vibrated, the elastic pins will become loose, and the shared items will be accidentally unlocked or popped out. [Summary of the invention]

[0004] The purpose of the present invention is to solve the above-mentioned technical problems and to propose a locking and unlocking structure for preventing shared items from being accidentally popped out. The structure can smoothly switch the locking and unlocking states of shared items and prevent the elastic pins from loosening when the shared cabinet is subjected to impact or vibration. The positioning locking and unlocking mechanism has a simple structure and is relatively energy-efficient.

[0005] To achieve the above-mentioned purpose, the present invention proposes a locking and unlocking structure that prevents shared items from accidentally popping out, including a shared cabinet, the shared cabinet can accommodate shared items in and out and is provided with a positioning mechanism and a rebound mechanism, the side of the shared item is provided with a positioning hole, the interior of the shared cabinet is provided with a cavity for accommodating shared items, the rear end of the shared cabinet is connected to a rebound mechanism, the outer side of the shared cabinet is installed with a positioning mechanism, the positioning mechanism includes an elastic positioning pin, a transmission plate, a tension spring, a locking and unlocking structure, the locking and unlocking structure includes a detection switch, a motor, a cam connected to the motor, and the middle of the transmission plate It is hinged with the shared cabinet through a rotating shaft, and an elastic locating pin is fixed at one end of the transmission plate, and the position of the elastic locating pin is matched with the shared item locating hole. A transmission hook is provided at the other end of the transmission plate, and the front end of the cam is a semicircular toggle plate, the outside is provided with a raised strip protruding outward, and the rear end is connected to the output end of the motor, the semicircular toggle plate is matched with the transmission hook, and the raised strip is matched with the detection switch fixed on the outside of the shared cabinet. When the cam rotates, it pushes the transmission plate to rotate, and the transmission plate drives the elastic locating pin to disengage from the locating hole. One end of the tension spring is fixed to the transmission plate, and the other end is fixed to the shared cabinet.The elastic locating pin of the present invention is connected to one end of the transmission plate. When the shared item is inserted, the elastic locating pin can enter the shared item locating hole to prevent the shared item from being pulled out. The transmission plate is pushed in the opposite direction at the other end of the transmission plate, so that the elastic locating pin can be disengaged from the locating hole to remove the shared item. Regarding the combined fixing structure of the transmission plate and the elastic locating pin, when the shared cabinet is subjected to impact or vibration, the transmission plate will not be locked and will become loose, so that a gap will be generated between the elastic locating pin and the locating hole, destroying the locking relationship of the elastic locating pin to the locating hole, thereby causing the shared item to be accidentally ejected. The locking and unlocking structure in the present invention locks and unlocks the transmission plate in the positioning mechanism, eliminating the problem of loose transmission plate caused by impact or vibration. The motor used is a stepping motor that can rotate forward and backward. Specifically, when the shared item is inserted into the shared cabinet, the position of the transmission plate is not limited and can be rotated, and the elastic locating pin can be stuck in the shared item locating hole. When the shared cabinet detects that the shared item is inserted in place or charging begins, a locking signal is sent, and the cam is initially in position. The inner plane of the semicircular toggle plate is arranged to be parallel to and close to the transmission plate. After the motor receives the locking signal, it starts to drive the cam to rotate in the positive direction. The detection switch detects the position of the cam bar. After the motor stops, the inner plane of the semicircular toggle plate of the cam is just vertically blocked on one side of the transmission hook of the transmission plate, preventing the transmission plate from rotating to that side. In this way, the relative position of the elastic locating pin and the locating hole will not change, thereby locking the transmission plate. When the shared item needs to be pulled out of the shared cabinet, the user sends a retrieval signal to take the shared item. After receiving the retrieval signal, the motor starts to drive the cam to rotate in the reverse direction. After the cam returns to its initial position for the first time, it continues to rotate in the reverse direction. The inner plane of the semicircular toggle plate of the cam pushes the transmission plate to rotate on the other side of the transmission hook of the transmission plate, thereby unlocking the transmission plate and opening the elastic locating pin to lock the shared item. Then the cam continues to rotate in the reverse direction. Since the outer side of the semicircular toggle plate of the cam is a smooth circle, the transmission plate can be reset under the action of the tension spring. The detection switch detects the position of the cam bar, and the motor stops after the cam returns to its initial position for the second time. There are locating holes on both sides of the shared item.

[0006] Preferably, the front end of the shared cabinet is provided with a flip door, the rear end of the shared cabinet is connected with a channel and a charging connector connected to the cavity, the rebound mechanism includes a plug, a spring and a slider, the two ends of the spring are respectively connected to the plug and the slider, the slider is inserted into the channel and can slide linearly inside the channel, the elastic positioning pin abuts against the side of the slider, the shared item pushes the slider backward when inserted into the cavity so that the end of the elastic positioning pin is plugged into the positioning hole set on the shared item, the charging interface set on the shared item is connected to the charging connector after the shared item is inserted into the cavity, the end of the elastic positioning pin is disengaged from the positioning hole set on the shared item and abuts against the side of the slider again when the shared item is pulled out of the cavity, the detection switch is a bidirectional detection switch, and the detection switch and the charging connector are connected to the second circuit board. In the detection switch of this scheme, the raised bar of the cam will trigger the detection switch when passing by, thereby sending a raised bar position signal to control the stop position of the motor rotation.

[0037] A groove is provided at the rear end of the slider 15, and a mounting cavity is provided at the front end of the plug 13. Both ends of the spring 14 are respectively inserted into and fixed in the corresponding groove and mounting cavity.

[0038] The horizontal cross-section of the cavity is funnel-shaped. After the shared item 2 is inserted into the cavity, the end of the shared item 2 with the charging interface is just inserted into the narrowed end of the cavity, and the charging connector and the charging interface are just docked in the narrowed end of the cavity.

[0039] Working process of the present invention:

[0040] The present invention provides a locking and unlocking structure for preventing a shared item from accidentally popping out. During operation, when the shared item 2 needs to be charged, one end of the shared item 2 with a charging interface is inserted into the cavity of the shared cabinet 1. The shared item 2 pushes the flip door 4 to flip, and the flip door 4 triggers a pressure detection switch. The pressure detection switch sends a signal, indicating that a shared item 2 has entered the shared cabinet 1. When the shared item 2 is inserted into the cavity, it pushes the slider 15 until the top end (spherical end) of the elastic positioning pin 5 is just inserted into the positioning hole 3 on one side of the shared item 2. At this time, the shared item 2 Item 2 is just locked in the cavity and the charging connector is just docked with the charging interface of the shared item 2, and the spring 14 is in a compressed state; the initial position of the cam 20 is that the inner plane of the semicircular ring-shaped toggle piece 21 is parallel to and close to the transmission piece 6. After receiving the locking signal, the motor 9 starts to drive the cam 20 to rotate in the positive direction, and the detection switch 8 detects the position of the cam bar 22. After the motor 9 stops, the inner plane of the semicircular ring-shaped toggle piece 21 of the cam 20 is just vertically blocked on one side of the transmission hook 61 of the transmission piece 6, preventing the transmission piece 6 from retracting, thereby locking the transmission piece 6;

[0041] When the user needs to take the shared item 2, the user sends a signal to take the shared item 2. After receiving the signal, the motor 9 starts to drive the cam 20 to rotate in the reverse direction. After the cam 20 returns to its initial position for the first time, it continues to rotate in the reverse direction. The inner plane of the semicircular ring-shaped toggle piece 21 of the cam 20 pushes the transmission piece 6 to rotate on the other side of the transmission hook 61 of the transmission piece 6, thereby unlocking the transmission piece 6, driving the elastic positioning pin 5 to rotate together, thereby opening the lock of the elastic positioning pin 5 on the shared item 2, and then the cam 20 continues to rotate in the reverse direction. Since the outer side of the semicircular ring-shaped toggle piece 21 of the cam 20 is a smooth circle, the transmission piece 6 can be reset under the action of the tension spring 7. The rotation and reset of the transmission piece 6 is also limited by the limiting groove 10 and the limiting pin 11. The detection switch 8 detects the position of the cam bar 22. After the cam 20 returns to its initial position for the second time, the motor 9 stops.

[0042] After the transmission plate 6 drives the elastic positioning pin 5 to disengage from the positioning hole 3, the spring 14 begins to reset and pushes the slider 15 to move horizontally forward along the channel 12. The horizontal forward movement of the slider 15 will push the shared item 2 to pop out from the shared cabinet 1. When the shared item 2 is taken out, the flip door 4 resets and removes the pressure detection switch. The pressure detection switch sends a signal, indicating that the shared item 2 has been taken out of the shared cabinet 1.

[0043] Among them, when the shared item 2 is inserted into the cavity, the ball head end of the spring ball head plunger is pressed down, and during the horizontal forward movement of the shared item 2, the ball head end of the spring ball head plunger blocks the shared item 2. The shared item 2 is provided with a blocking structure (such as a groove) cooperating with the spring ball head plunger, which can prevent the shared item 2 from being excessively ejected when being ejected by the spring 14, causing the shared item 2 to fall. After the shared item 2 is blocked halfway after being ejected, the user can extract the shared item 2 by hand, because the force exerted by the hand on the shared item 2 is greater than the resistance of the spring ball head plunger to the shared item 2, the ball head end of the spring ball head plunger can be pressed down again so that the shared item 2 can be smoothly extracted. After the user removes the shared item 2, the flip door 4 is closed again under the resetting action of the torsion spring.

[0044] The elastic locating pin mentioned in the present application is not limited to a spring steel ball pin. Without affecting the use, the elastic locating head may also adopt an interconnected spring and steel ball structure. Without affecting the use, an electromagnetic drive control structure may also be used to realize the electric control of the extension and retraction of the elastic locating head.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
