[0023] The present invention will be further described below with reference to the embodiments.

[0024] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0025] Please see Figures 1-8 This utility model provides a locking mechanism for a power bank rental cabinet, including a rental cabinet shell 1, a power bank storage compartment 2 inside the rental cabinet shell 1, a power bank socket on the front of the rental cabinet shell 1, the power bank socket and the power bank storage compartment 2 are corresponding to each other, and there are several power bank sockets and power bank storage compartments 2. A circuit board 3 is fixedly installed inside the rental cabinet shell 1, and the power bank storage compartment 2 and the circuit board 3 are connected through an interface 10. The output end of the circuit board 3 is electrically connected to a motor 4, and the motor 4 is fixedly connected to the circuit board 3 through a mounting bracket.

[0026] In this embodiment, the shared power bank inside the power bank storage compartment 2 can be taken out through the power bank socket, or the shared power bank can be put into the power bank storage compartment 2. Using the interface 10, an electrical connection can be made between the power bank storage compartment 2 and the circuit board 3, that is, the shared power bank inside the power bank storage compartment 2 can be charged. The circuit board 3 can control the operating state of the motor 4, and the motor 4 can rotate in both directions.

[0027] A locking block 5 is fixedly sleeved on the output shaft of motor 4. A buckle 6 is provided at the bottom of the locking block 5. The bottom of the locking block 5 and the top of the buckle 6 are in contact. A rotating shaft 7 is movably passed through the inside of the buckle 6. The end of the rotating shaft 7 is fixedly connected to the inside of the rental cabinet shell 1. A buckle spring 8 is provided at the bottom of the top of the buckle 6. The two ends of the buckle spring 8 are fixedly connected to the top of the circuit board 3 and the bottom of the top of the buckle 6, respectively. A buckle groove 9 is opened on the top of the side of the power bank placement compartment 2. The buckle groove 9 is adapted to the bottom of the buckle 6. A pin 11 is provided on the circuit board 3. A pin spring 12 is sleeved on the outside of the pin 11. The pin 11 passes through the inside of the power bank placement compartment 2 and is located on the side of motor 4.

[0028] In this embodiment, the locking block 5 is a concave disc shape, that is, half of the locking block 5 is a normal semi-circle, and the other half is concave downward. When it is necessary to take the shared power bank, the motor 4 is started, which causes the motor 4 to drive the locking block 5 to rotate. At this time, the concave part of the locking block 5 will move closer to the top of the buckle 6 and squeeze the top of the buckle 6. The buckle spring 8 will be compressed and deformed. At the same time, the buckle 6 will rotate with the rotating shaft 7, causing the bottom end of the buckle 6 to lift up. The bottom end of the buckle 6 will move out of the inside of the buckle groove 9, causing the bottom end of the buckle 6 to separate from the shared power bank inside the power bank placement compartment 2. In this way, the buckle 6 will release the shared power bank inside the power bank placement compartment 2. At the same time, the compressed ejector spring 12 needs to restore its elastic deformation and drive the ejector pin 11 to move. The ejector pin 11 can be used to lift the shared power bank inside the power bank placement compartment 2, which makes it convenient for people to take the shared power bank.

[0029] When returning a shared power bank, first insert the power bank into the power bank storage compartment 2 through the power bank socket, and press down on the power bank. This will cause the power bank to apply force to the pin 11, causing the pin 11 to move and compress the pin spring 12. At the same time, the motor 4 will be activated, causing the locking block 5 to rotate in the opposite direction. At this time, the recessed part of the locking block 5 will separate from the top of the buckle 6. The compressed buckle spring 8 needs to recover its elastic deformation and apply force to the top of the buckle 6, causing the top of the buckle 6 to lift up. At this time, the buckle 6 will rotate with the rotating shaft 7, causing the bottom of the buckle 6 to move downward until the bottom of the buckle 6 is engaged inside the buckle groove 9. At the same time, the bottom of the buckle 6 will contact the shared power bank inside the power bank storage compartment 2, thus facilitating the clamping and locking of the shared power bank.

[0030] In the above scheme, it should be noted that when the shared power bank is locked, the bottom end of the buckle 6 will penetrate through the buckle groove 9 and extend into the interior of the power bank placement compartment 2, so that the bottom end of the buckle 6 contacts the side surface of the shared power bank. In this way, it is not necessary to open a buckle groove that matches the buckle 6 on the surface of the shared power bank during the manufacturing process. At the same time, by rotating a set of motors 4 and locking blocks 5 in both directions, the two buckles 6 can be controlled, that is, the shared power banks inside the two power bank placement compartments 2 can be locked or unlocked.

[0031] The specific operating procedure is as follows: Since half of the locking block 5 is a normal semi-circle and the other half is concave, when the initial state of the locking mechanism is as shown in the attached instruction manual... Figure 6 As shown, since the normal semicircular part of the locking block 5 is located above the tops of the two latches 6, the motor 4 first drives the locking block 5 to rotate 90 degrees in the forward direction. At this time, the concave part of the locking block 5 will press against the top of one latch 6, while half of the normal semicircular part of the locking block 5 will be located on the top of the other latch 6. At this time, the top of the other latch 6 is not pressed. If, in this state, the motor 4 drives the locking block 5 to rotate 90 degrees in the reverse direction, the concave part of the locking block 5 will separate from the top of the latch 6 that was just pressed. At this time, the state of the locking block 5 returns to the state specified in the instruction manual. Figure 6 The initial state, similarly, when it first appears in the instruction manual... Figure 6 In the initial state, the motor 4 drives the locking block 5 to rotate 90 degrees in the opposite direction, which allows control of the other latch 6.

[0032] The surface of the rental cabinet shell 1 is equipped with a scanning code (the scanning code is the technical means of existing power bank rental cabinets). Users can use their mobile phones to scan and identify the scanning code, and operate through the program page set by the scanning code. The circuit board 3 is then used to control the running status of the motor 4.

[0033] Since the control program set inside the scanning code and the working principle of the circuit board 3 controlling the motor 4 are both publicly available technologies of existing power bank rental cabinets, and the technical solution of this application is to improve the locking mechanism of the shared power bank inside the power bank rental cabinet, it does not involve improvements to the control program. Therefore, the control program will not be described in detail. You can refer to the existing power bank rental cabinet control programs and methods.

[0034] The working principle and usage process of this utility model are as follows: First, when it is necessary to take a shared power bank, start the motor 4, so that the motor 4 drives the locking block 5 to rotate. At this time, the recessed part of the locking block 5 will move closer to the top of the buckle 6 and squeeze the top of the buckle 6. The buckle spring 8 will be compressed and deformed. At the same time, the buckle 6 will rotate with the rotating shaft 7, causing the bottom of the buckle 6 to lift up.

[0035] Next, the bottom end of the buckle 6 will move out from the inside of the buckle groove 9, causing the bottom end of the buckle 6 to separate from the shared power bank inside the power bank storage compartment 2. In this way, the buckle 6 will release the shared power bank inside the power bank storage compartment 2. At the same time, the compressed ejector spring 12 needs to restore its elastic deformation and drive the ejector pin 11 to move. The ejector pin 11 can be used to lift the shared power bank inside the power bank storage compartment 2, making it convenient for people to take the shared power bank.

[0036] Then, when returning the shared power bank, first insert the shared power bank into the power bank storage compartment 2 from the power bank socket, and press down on the shared power bank so that the shared power bank applies force to the pin 11, causing the pin 11 to move and squeeze the pin spring 12, causing the pin spring 12 to compress and deform.

[0037] Finally, start motor 4, which causes the locking block 5 to rotate in the opposite direction. At this time, the recessed part of the locking block 5 will separate from the top of the buckle 6, and the compressed buckle spring 8 needs to restore its elastic deformation and apply force to the top of the buckle 6, causing the top of the buckle 6 to lift up. At this time, the buckle 6 will rotate with the rotating shaft 7, causing the bottom of the buckle 6 to move downward until the bottom of the buckle 6 is engaged in the inside of the buckle groove 9. At the same time, the bottom of the buckle 6 will contact the shared power bank inside the power bank placement compartment 2, thus facilitating the clamping and locking of the shared power bank.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
