[0035] This invention discloses a power bank borrowing and returning device to improve the locking structure of the power bank, avoid opening lock holes on the surface of the power bank, and improve the visual experience of the power bank's ID appearance.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-5 , Figure 1 An exploded view of the mobile power bank borrowing and returning device provided in an embodiment of the present invention; Figure 2 This is a schematic diagram of the structure of the mobile power bank borrowing and returning device provided in an embodiment of the present invention; Figure 3 A schematic diagram of the mobile power bank borrowing and returning device provided in an embodiment of the present invention after being rotated 180°; Figure 4 This is a schematic diagram of the extended tray assembly of the mobile power bank borrowing and returning device provided in an embodiment of the present invention; Figure 5 This is a schematic diagram of the structure of the power bank borrowing and returning device provided in an embodiment of the present invention, perpendicular to the direction of the power bank entering and exiting.

[0038] The present invention discloses a mobile power bank borrowing and returning device, including a battery compartment 1, a tray assembly 3 disposed in the battery compartment 1, and a driving assembly for driving the tray assembly 3 to enter and exit the battery compartment 1.

[0039] One end of the battery compartment 1 is an open end for the tray assembly 3 to enter and exit, and the other end of the battery compartment 1 is a closed end. The tray assembly 3 enters and exits the battery compartment 1 through the open end.

[0040] The tray assembly 3 is used to support the power bank and to limit the outer perimeter of the power bank.

[0041] The drive component drives the tray assembly 3 to enter and exit the battery compartment 1, providing power for the movement of the tray assembly 3. When the tray assembly 3 is outside the battery compartment 1, it is used to take the power bank from the tray assembly 3 or place the power bank into the tray assembly 3. When the tray assembly 3 is inside the battery compartment 1, it cannot be used to take or place the power bank.

[0042] This solution uses the tray assembly 3 to lock the outer periphery of the power bank. Preferably, the shape formed by the limiting plate is adapted to the outer periphery of the power bank, effectively limiting the movement of the power bank at various points on its periphery and reducing its sliding within the tray assembly 3, thus achieving effective locking of the power bank's outer periphery. When the power bank enters or exits the battery compartment, the tray assembly drives its movement; that is, the sliding of the tray assembly replaces the sliding of the power bank in existing technologies, thereby effectively reducing wear and tear on the power bank.

[0043] This solution uses tray component 3 to lock the power bank in place, eliminating the need for a lock hole on the power bank and requiring no modifications to the power bank itself, thus effectively improving the visual appeal of the power bank.

[0044] This solution adds a tray assembly 3, which locks the power bank in place without requiring a separate locking structure. This simplifies the structure of the power bank borrowing and returning device and reduces costs to some extent.

[0045] In this embodiment of the invention, the power bank moves synchronously with the tray assembly, and there is no relative sliding between the power bank and the tray assembly. This effectively reduces the friction between the surface of the power bank and the contact surface of the power bank borrowing and returning device, thus extending the service life of the power bank.

[0046] The portable power bank borrowing and returning device provided by the present invention includes a battery compartment 1 comprising an upper cover 11, a lower cover 12, and a rear plate 13. The upper cover 11 and the lower cover 12 are disposed opposite to each other. The lower cover 12 has a first sliding groove 121 that mates with a tray assembly 3, and the upper cover 11 has a second sliding groove 111 that mates with a portable power bank. After the upper cover 11 and the lower cover 12 are engaged, the first sliding groove 121 and the second sliding groove 111 communicate to form a cavity, within which the battery and the tray assembly 3 move. One end of the cavity is an open end for the battery compartment 1 to enter and exit, and the other end of the cavity is sealed by the rear plate 13 to form a closed end.

[0047] In one specific embodiment of this solution, the wall thickness of the lower cover 12 is less than the wall thickness of the upper cover 11, that is, the wall thickness of the first slide groove is smaller than the wall thickness of the second slide groove, and the width of the first slide groove is greater than the width of the second slide groove. The outer wall width of the first slide groove is equal to the outer wall width of the first slide groove. It should be noted here that the wall thickness of the lower cover 12 and the upper cover 11 both refer to the thickness of the lower cover 12 and the upper cover 11 along the direction perpendicular to the direction in which the mobile power supply enters and exits the battery compartment 1.

[0048] Because the side wall thickness of the upper cover 11 is greater than that of the lower cover 12, after the upper cover 11 and the lower cover 12 are fitted together, the lower end face of the side wall of the upper cover 11 abuts against the upper end of the limiting plate. A guide groove for placing the tray assembly 3 is formed between the lower end face of the side wall of the upper cover 11 and the bottom wall of the lower cover 12. The tray slides along the bottom wall of the lower cover 12, the limiting plate slides along the guide groove, and the lower end face of the side wall of the upper cover 11 can press against the limiting plate. The difference in wall thickness between the upper cover 11 and the lower cover 12 forms a guiding structure for the tray assembly 3, ensuring that the tray assembly 3 can slide stably within the battery compartment 1.

[0049] In this embodiment of the invention, the tray assembly 3 drives the power bank to slide within the battery compartment 1, replacing the method in the prior art where the power bank slides directly within the battery compartment 1. The tray assembly 3 slides in place of the power bank, and the power bank slides synchronously with the tray assembly 3, thus preventing the power bank from sliding and protecting it.

[0050] Preferably, the difference in wall thickness between the upper cover 11 and the lower cover 12 is equal to the thickness of the limiting plate. It should be noted that the thickness of the limiting plate is the thickness along the direction perpendicular to the direction in which the power bank enters and exits the battery compartment 1. The design of the first slide groove 121 enables the lower cover 12 to guide the tray assembly 3, and the design of the second slide groove 111 enables the upper cover 11 to guide the power bank. In this embodiment of the invention, the first slide groove 121 of the lower cover 12 guides and limits the tray assembly 3, and the second slide groove 111 of the upper cover 11 guides and limits the portion of the power bank located outside the tray assembly 3.

[0051] The upper wall of the second slide groove 111 is provided with a pressing block 15, which is used to press the upper surface of the power bank. It should be noted that the upper wall of the second slide groove 111 is the inner wall of the second slide groove 111 corresponding to the upper surface of the power bank.

[0052] The pressure block 15 presses down on the top of the power bank to prevent it from moving up and down. This solution effectively locks the power bank in place by using the tray assembly 3 and the pressure block 15 together, preventing the power bank from moving along its circumference or up and down during handling, thus effectively reducing wear and tear on the power bank.

[0053] This embodiment of the invention adds a tray assembly 3 and a pressure block 15. The tray assembly 3 and the pressure block 15 work together to lock the power bank. Compared to a separate locking structure, this simplifies the structure of the power bank borrowing and returning device and reduces costs to some extent. In this embodiment, the upper cover 11 and the lower cover 12 are detachably connected. Specifically, the side wall of the upper cover 11 has a first connecting post, and the side wall of the lower cover 12 has a second connecting post corresponding to the position of the first connecting post. The first and second connecting posts are connected by bolts.

[0054] In one specific embodiment of the present invention, the second slide groove 111 has support bars 14 on both sides along its length, and the upper end face of the support bars 14 abuts against the tray assembly 3. Specifically, the support bars 14 are cuboid in shape, and the length of the support bars 14 is equal to the length of the lower cover 12. The distance between the two support bars 14 is less than the width of the tray to ensure effective support of the tray assembly 3 by the support bars 14. Preferably, the support bars 14 are arranged along the side wall of the lower cover 12.

[0055] In one specific embodiment of the present invention, the support strip 14 and the lower cover 12 are integrally formed.

[0056] The support bar 14 reduces the contact area between the tray assembly 3 and the lower cover 12, thereby reducing the friction between the tray assembly 3 and the lower cover 12, reducing wear on the tray assembly 3, and also reducing the difficulty of removing the power bank to some extent.

[0057] To further optimize the above technical solution, a guide slope is provided at the upper end of the limiting plate. The guide slope guides the power bank embedded tray assembly 3, ensuring that the power bank can be placed in place in one go.

[0058] In one specific embodiment of the present invention, the pressure block 15 and the top cover 11 are integrally formed, which reduces the manufacturing difficulty of the battery compartment 1.

[0059] Preferably, the length of the pressure block 15 along the length direction of the upper cover 11 is 1-3cm.

[0060] To reduce friction on the upper part of the power bank, the distance between the lower end face of the pressure block 15 and the upper end face of the power bank is 0.1-0.3mm, so that the upper surface of the power bank will not be worn when the power bank moves with the tray assembly.

[0061] To facilitate the removal of the power bank, the tray has a groove on the end for easy removal. When removing the power bank, fingers can directly contact the power bank through the groove to remove the battery, thus reducing the difficulty of removal.

[0062] In one specific embodiment of the present invention, the drive assembly includes a stepper motor, a lead screw 4, a nut, and a connecting plate.

[0063] Specifically, the stepper motor is connected to the battery compartment 1. In one specific embodiment of this solution, the stepper motor is connected to the lower cover 12 of the battery compartment 1.

[0064] Lead screw 4 is connected to the output shaft of the stepper motor;

[0065] The nut is located on the lead screw 4 and is connected to the tray assembly 3 via a connecting plate.

[0066] Specifically, the connecting plate is an L-shaped connecting plate 5, one end of which is connected to a nut, and the other end is connected to the tray assembly 3. A sliding hole is provided on the battery compartment 1 for the L-shaped connecting plate 5 to move. In one specific embodiment of this solution, the lower cover 12 has a sliding hole.

[0067] Specifically, the sliding hole has a certain length, and after the tray assembly slides out of the battery compartment along the sliding hole, it can facilitate the loading and unloading of the power bank.

[0068] The stepper motor drives the lead screw 4 to rotate, causing the nut to move along the axis of the lead screw 4. The nut drives the tray assembly 3 to move through the connecting plate 5, moving in and out of the battery compartment 1.

[0069] The stepper motors rotate in different directions, and the tray assembly 3 moves in the opposite direction.

[0070] In one specific embodiment of the present invention, a sensor switch and a circuit board communicating with the sensor switch are provided on the rear plate 13. The circuit board is communicating with a mobile APP application, allowing the user to send signals to the power bank borrowing and returning device via the mobile APP to perform the borrowing and returning operation of the power bank.

[0071] In this embodiment of the invention, the step of borrowing a portable power bank is as follows:

[0072] The power bank borrowing and returning device receives a borrowing signal from the mobile app;

[0073] The stepper motor drives the lead screw 4 to rotate in the forward direction, causing the nut to move along the axis of the lead screw 4, and the nut drives the L-shaped connecting plate 5 to move.

[0074] L-shaped connecting plate 5 drives tray 3 to slide along battery compartment 2, and tray 3 is sent out of battery compartment 2.

[0075] The user takes the power bank through the groove in tray 3;

[0076] The user confirms successful borrowing of the power bank via the mobile app;

[0077] The stepper motor drives the lead screw 4 to rotate in the opposite direction, causing the nut to move along the axis of the lead screw 4, and the nut drives the L-shaped connecting plate 5 to move.

[0078] The L-shaped connecting plate 5 drives the tray 3 to slide along the battery compartment 2, and the tray 3 retracts into the battery compartment 2.

[0079] The steps to return the power bank are as follows:

[0080] The power bank lending and returning device receives a signal from a mobile app to return the power bank;

[0081] The stepper motor drives the lead screw 4 to rotate in the forward direction, causing the nut to move along the axis of the lead screw 4, and the nut drives the L-shaped connecting plate 5 to move.

[0082] L-shaped connecting plate 5 drives tray 3 to slide along battery compartment 2, and tray 3 is sent out of battery compartment 2.

[0083] The user places the returned power bank back into tray 3;

[0084] The user confirms the power bank has been successfully returned via the mobile app;

[0085] The stepper motor drives the lead screw 4 to rotate in the opposite direction, causing the nut to move along the axis of the lead screw 4, and the nut drives the L-shaped connecting plate 5 to move.

[0086] The L-shaped connecting plate 5 drives the tray 3 to slide along the battery compartment 2, and the tray 3 and the power bank are retracted into the battery compartment 2.

[0087] The embodiments of the present invention improve the working accuracy and reliability of the mobile power bank borrowing and returning device through the design of the inductive switch and circuit board.

[0088] In order to improve the wear resistance and sliding properties of the upper cover 11, lower cover 12 and tray assembly 3, the upper cover 11, lower cover 12 and tray assembly 3 are made of ROM material in this embodiment of the invention.

[0089] The number of pressure blocks 15 is at least two. In a specific embodiment of the present invention, the number of pressure blocks 15 is three, and they are evenly arranged along the width direction of the upper cover 11. The dimensions of the pressure blocks 15 in the direction perpendicular to the surface of the power bank are set according to the surface shape of the power bank.
