Description

Technical Field

[0001] This application relates to the field of power bank locking devices, and in particular to a locking compartment structure for a shared power bank and a power bank cabinet. Background Technology

[0002] Shared power bank lockers are common service facilities in public places, where users rent and return power banks by scanning a QR code. These lockers are usually located in areas with high traffic and complex environments, and need to withstand frequent daily pick-up and drop-off operations by users.

[0003] Currently, to control costs, most shared power bank cabinets in the industry use a single-sided locking structure to secure the power banks inside. This single-sided locking structure includes a hook driven by a spring or elastic element; when the power bank is inserted, the hook automatically engages with a groove on the side of the power bank, securing it in place.

[0004] However, in actual operation, power bank lockers are often tipped over or dropped due to accidental collisions or malicious acts, resulting in severe impacts. At the moment of impact, the power bank generates a huge instantaneous force due to inertia. Existing single-sided locking mechanisms rely solely on spring force to maintain the lock; under this impact force, the hook is easily squeezed backward and dislodged from the power bank's recess, causing the power bank to fall out of the locker and potentially resulting in property damage. Summary of the Invention

[0005] To address the aforementioned technical issues, this application provides a locking compartment structure and a power bank cabinet for shared power banks, which can reduce the chance of power banks accidentally falling off and thus minimize property loss.

[0006] The technical solution provided in this application is described below: The first aspect of this application provides a locking compartment structure for a shared power bank, including: Charging compartment and locking mechanism; The charging compartment has multiple rows of chambers for holding power banks, with two chambers arranged side by side in the same row; The locking mechanism is correspondingly arranged between the two chambers in each row; The locking mechanism includes a drive member and two locking tongues that are controlled to extend and retract by the drive member, with the two locking tongues extending toward the two chambers in the same row, respectively. An opening is provided on the side wall of the chamber facing the locking mechanism. When the locking tongue extends, it passes through the corresponding opening and engages with the groove on the side of the power bank inside the chamber. The latch has a first inclined surface on the side facing the direction of the power bank being removed, and a second inclined surface is provided on the opening. When the latch engages with the groove, the first inclined surface and the second inclined surface are opposite to each other and spaced apart. When the power bank is subjected to an impact that tends to fall off, the first inclined surface and the second inclined surface abut and interfere with each other.

[0007] Optionally, the driving component is a drive motor, and the locking mechanism further includes a housing and two locking rods, with the housing disposed between the two chambers in each row; The drive motor is fixed inside the housing. Rotary shafts are provided on both sides of the drive motor inside the housing. The two locking rods are located on both sides of the drive motor and are movably connected to the corresponding rotating shafts. A cam is provided between the first end of the locking rod and the drive motor, and the locking tongue is provided on the second end of the locking rod. The drive motor is used to control the locking rod to rotate around the rotating shaft through the cam.

[0008] Optionally, a spring is provided between the second ends of the two locking rods.

[0009] Optionally, a damping assembly is provided inside the housing. One end of the damping assembly is connected to the housing, and the other end is connected to the second end of the locking rod. When the bolt retracts due to impact, the damping assembly is used to provide a damping force to prevent the bolt from retracting.

[0010] Optionally, the damping assembly includes a miniature damping cylinder and a piston, wherein the miniature damping cylinder is fixed inside the housing, and the axial direction of the miniature damping cylinder is parallel to the retraction direction of the latch. The piston is disposed inside the cylinder of the micro damping cylinder, and divides the cylinder into two fluid chambers, which are filled with damping fluid; The piston is connected to the latch via a piston rod.

[0011] Optionally, the first inclined surface and the second inclined surface are parallel to each other, and when the locking tongue engages with the groove, the gap between the first inclined surface and the second inclined surface is 0.2mm-0.5mm.

[0012] Optionally, the angle between the second inclined plane and the direction in which the power bank is placed is in the range of 30° to 60°.

[0013] Optionally, anti-slip textures are provided on the first inclined surface and the second inclined surface respectively.

[0014] Optionally, the locking tongue includes a locking portion for engaging with a groove on the side of the power bank; The engaging part has a guide arc surface on the side facing the direction in which the power bank is inserted; The locking part forms a locking plane on the side opposite to the direction in which the power bank is inserted. The locking plane is used to abut against the side wall of the groove and is perpendicular to the direction in which the power bank is inserted.

[0015] The second aspect of this application provides a power bank cabinet, including the locking compartment structure described in the first aspect and any optional method of the first aspect.

[0016] As can be seen from the above technical solutions, this application has the following beneficial effects: This application achieves locking and unlocking of two power banks in the same row by simultaneously setting two locking tongues on a locking mechanism.

[0017] By providing a first inclined surface on the side of the locking tongue facing the direction in which the power bank is to be removed, and a second inclined surface corresponding to the first inclined surface on the opening of the chamber sidewall, when the locking tongue engages with the groove of the power bank, the first and second inclined surfaces are opposite to each other and spaced apart. When the power bank is subjected to an impact that tends to fall off, the first and second inclined surfaces abut and interfere with each other. Under the frictional force generated by the mutual interference of the two inclined surfaces, the first inclined surface is difficult to separate from the second inclined surface, thus making it difficult for the locking tongue to retract. This reduces the possibility of the power bank falling off due to tipping, thereby reducing property damage. Attached Figure Description

[0023] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] To address the issue of traditional power bank cabinets experiencing single-sided latch retraction and power bank detachment due to tipping or falls, this application proposes a locking compartment structure and power bank cabinet for shared power banks to reduce accidental power bank detachment and minimize property loss. The specific implementation structure of this application is described below: See Figures 1 to 12 This application provides an embodiment of a locking compartment structure for a shared power bank, the embodiment including: The charging compartment 01 and the locking mechanism 02 are provided. The charging compartment 01 has multiple rows of chambers 03 for placing power banks 06, with two chambers 03 arranged side by side in the same row. The locking mechanism 02 is correspondingly arranged between the two chambers 03 in each row. The locking mechanism 02 includes a driving member and two locking tongues 04 that are controlled to extend and retract by the driving member. The two locking tongues 04 extend toward the two chambers 03 in the same row respectively. An opening 05 is provided on the side wall of the chamber 03 facing the locking mechanism 02. When the locking tongue 04 extends, it passes through the corresponding opening 05 and engages with the groove 07 on the side of the power bank 06 in the chamber 03. A first inclined surface 08 is provided on the side of the locking tongue 04 facing the direction of taking out the power bank 06, and a second inclined surface 09 is provided on the opening 05. When the locking tongue 04 engages with the groove 07, the first inclined surface 08 and the second inclined surface 09 are opposite to each other and spaced apart. When the power bank 06 is impacted by the tendency to fall, the first inclined surface 08 and the second inclined surface 09 abut and interfere.

[0025] The charging compartment 01 has multiple rows of chambers 03 for accommodating power banks 06. Each row has two chambers 03, which are arranged side by side in the horizontal direction. On the side wall of the chamber 03 facing the adjacent chamber 03 in the same row, there is a rectangular opening 05, through which the locking tongue 04 can pass and engage with the side wall groove 07 of the power bank 06 inside the chamber 03.

[0026] The locking mechanism 02 is correspondingly disposed between the two chambers 03 in each row. The locking mechanism 02 includes a driving member and two locking tongues 04. The driving member is fixedly installed inside the locking mechanism 02 and serves as a power source, typically a miniature drive motor 10 or an electromagnet.

[0027] The two latches 04 are controlled by a drive unit and extend toward the two chambers 03 on the left and right sides of the same row. Each latch 04 has a hook-shaped or block-shaped engaging part at its front end, which is used to engage with the groove 07 on the side of the power bank 06.

[0028] In this embodiment, the locking mechanism 02 is fixed to a predetermined position on the charging compartment 01 by bolts or buckles, ensuring that its two locking tongues 04 can accurately enter and exit the openings 05 on the side wall of the chamber 03.

[0029] In the locked state, the front end of the locking tongue 04 passes through the opening 05 and enters the interior of the chamber 03, and precisely engages in the reserved groove 07 on the side of the power bank 06, thereby preventing the power bank 06 from being directly removed.

[0030] A first inclined surface 08 is machined on the side of the locking tongue 04 facing the direction in which the power bank 06 is removed. A second inclined surface 09 is machined at the edge of the opening 05 on the side wall of the chamber 03, corresponding to the position of the first inclined surface 08. In the normal locked state, the first inclined surface 08 and the second inclined surface 09 are relatively parallel and maintain a small gap (e.g., 0.3mm). When the charging cabinet is subjected to impacts such as drops, the power bank 06 generates a huge falling force due to inertia, forcing the locking tongue 04 to retract. At this time, the small gap between the first inclined surface 08 and the second inclined surface 09 disappears, and the two inclined surfaces abut and interfere with each other. This interference transforms the retraction movement of the locking tongue 04 into a compressive force on the side wall, thus creating a self-locking effect. This effectively prevents further retraction of the locking tongue 04, ensuring the locking reliability of the power bank 06 under extreme conditions.

[0031] An integrally formed protrusion is provided on the opening 05 on the side wall of the chamber 03, and the second inclined surface 09 is provided on the protrusion.

[0032] In this embodiment, by simultaneously providing two locking tongues 04 on a locking mechanism 02, the locking and unlocking of two power banks 06 in the same row can be achieved.

[0033] By providing a first inclined surface 08 on the side of the locking tongue 04 facing the direction in which the power bank 06 is to be removed, and a second inclined surface 09 corresponding to the first inclined surface 08 on the opening 05 of the side wall of the chamber 03, when the locking tongue 04 engages with the groove 07 of the power bank 06, the first inclined surface 08 and the second inclined surface 09 are opposite each other and spaced apart. When the power bank 06 is subjected to an impact that tends to fall off, the first inclined surface 08 and the second inclined surface 09 come into contact and interfere. Under the condition that the two inclined surfaces interfere with each other and generate friction, the first inclined surface 08 is difficult to separate from the second inclined surface 09, and thus the locking tongue 04 is difficult to retract. This can reduce the possibility of the power bank 06 falling off due to tipping, and reduce property damage.

[0034] Please continue reading. Figure 8In an optional embodiment, the driving component is a drive motor 10, and the locking mechanism 02 further includes a housing 11 and two locking rods 12. The housing 11 is disposed between two chambers 03 in each row. The drive motor 10 is fixed inside the housing 11, and a rotating shaft is disposed inside the housing 11 corresponding to both sides of the drive motor 10. The two locking rods 12 are respectively located on both sides of the drive motor 10 and are movably connected to the corresponding rotating shafts. A cam 13 is disposed between the first end of the locking rod 12 and the drive motor 10, and a locking tongue 04 is disposed on the second end of the locking rod 12. The drive motor 10 is used to control the locking rod 12 to rotate around the rotating shaft through the cam 13.

[0035] The locking mechanism 02 of this embodiment includes a sealed housing 11, and a drive motor 10, which serves as a driving component, is fixedly installed inside the housing 11. On each side of the drive motor 10, a rotating shaft is provided on the housing 11.

[0036] There are two locking rods 12, located on the left and right sides of the drive motor 10, respectively. Each locking rod 12 is movably sleeved onto a corresponding rotating shaft through a shaft hole, allowing the locking rod 12 to rotate within a certain angle around the rotating shaft. A cam 13 is provided between the first end of the locking rod 12 (the end closer to the drive motor 10) and the output shaft of the drive motor 10. When the drive motor 10 rotates, the cam 13 pushes the first end of the locking rod 12 to move, thereby driving the entire locking rod 12 to swing around the rotating shaft.

[0037] The locking tongue 04 is fixedly installed at the second end of the locking rod 12 (the end furthest from the drive motor 10). Therefore, the rotational motion of the drive motor 10 is converted into the oscillation of the locking rod 12 through the cam 13, ultimately driving the locking tongue 04 to achieve an arc-shaped extension and retraction motion. It should be noted that this arc-shaped motion is tangent to the first inclined plane 08.

[0038] Please continue reading. Figure 8 In this optional embodiment, a spring 14 is provided between the second ends of the two locking rods 12.

[0039] To further optimize the smoothness of the operation and ensure that the lock is fully engaged, a spring 14 is connected between the second ends of the two locking levers 12. The function of the spring 14 is to provide elasticity so that the two locking tongues 04 remain in the extended position when there is no drive.

[0040] Please continue reading. Figure 10 and Figure 11 In this optional embodiment, a damping component 20 is provided inside the housing 11. One end of the damping component 20 is connected to the housing 11, and the other end is connected to the second end of the locking rod 12. When the locking tongue 04 retracts due to impact, the damping component 20 is used to provide a damping force to prevent the locking tongue 04 from retracting.

[0041] In an optional embodiment, the damping assembly 20 includes: a miniature damping cylinder 15 and a piston 16. The miniature damping cylinder 15 is fixed inside the housing 11, and the axial direction of the miniature damping cylinder 15 is parallel to the retraction direction of the latch 04. The piston 16 is disposed inside the cylinder of the miniature damping cylinder 15 and divides the cylinder into two fluid chambers, which are filled with damping fluid. The piston 16 is connected to the latch 04 through a piston rod 17.

[0042] The damping assembly 20 is integrated inside the housing 11 of the locking mechanism 02. The miniature damping cylinder 15 in the damping assembly 20 is fixed to the inner wall of the housing 11 (by screws), and the installation direction of the miniature damping cylinder 15 is parallel to the retraction direction of the locking tongue 04.

[0043] A piston 16 is installed inside the miniature damping cylinder 15. The piston 16 divides the inside of the cylinder of the miniature damping cylinder 15 into two closed fluid chambers, which are filled with damping fluids such as silicone oil of a certain viscosity. The piston 16 is rigidly connected to the second end of the locking rod 12 (or directly to the tail of the locking tongue 04) through a piston rod 17.

[0044] During normal locking and unlocking, the drive motor 10 smoothly drives the locking lever 12 to swing through the cam 13. At this time, the piston 16 moves slowly in the micro damping cylinder 15. The damping fluid can flow through the throttle hole on the piston 16 with low resistance, and the first damping force generated is very small, which will not affect the normal operating speed and user experience.

[0045] When the power bank 06 cabinet is subjected to a severe impact, the impact force attempts to force the latch 04 to retract at high speed, and through the locking rod 12, drives the piston rod 17 and piston 16 to attempt high-speed movement within the miniature damping cylinder 15. At this time, the damping fluid cannot pass through the throttling orifice on the piston 16 in time, resulting in huge flow resistance and forming a suddenly increased second damping force. This second damping force reacts through the piston rod 17 to the locking rod 12 and the latch 04, strongly inhibiting or even locking the retraction movement of the latch 04.

[0046] The damping component 20 of this embodiment works in conjunction with the inclined plane interference in the aforementioned embodiment to achieve dual anti-reverse under tipping impact force, greatly improving reliability.

[0047] Understandably, the normal unlocking requirements can be met by increasing the orifice diameter or replacing it with a damping fluid with lower resistance, but it can still maintain a large resistance when subjected to impact.

[0048] In an optional embodiment, the first inclined surface 08 and the second inclined surface 09 are parallel to each other, and when the latch 04 is engaged with the groove 07, the gap between the first inclined surface 08 and the second inclined surface 09 is 0.2mm-0.5mm.

[0049] The first inclined surface 08 and the second inclined surface 09 remain parallel in the locked state, and the gap between them is set to 0.2mm to 0.5mm (e.g., 0.3mm). The gap of 0.2mm-0.5mm ensures that the self-locking mechanism can be triggered instantaneously when an impact occurs, while ensuring smooth assembly.

[0050] In an optional embodiment, the angle between the second inclined plane 09 and the direction in which the power bank 06 is placed ranges from 30° to 60°.

[0051] The angle between the second inclined plane 09 and the direction in which the power bank 06 is placed is set between 30° and 60° (preferably 45°).

[0052] In an optional embodiment, anti-slip textures are provided on the first inclined surface 08 and the second inclined surface 09, respectively.

[0053] On the surfaces of the first inclined surface 08 and / or the second inclined surface 09, fine anti-slip textures (such as mesh patterns or serrated patterns) are machined.

[0054] When an impact occurs, at the instant the two inclined surfaces come into contact and interfere, the anti-slip texture on the surface increases the static friction coefficient between the contact surfaces, preventing relative sliding between them. This more effectively converts the impact energy into rigid resistance to the retraction movement of the locking tongue 04, further improving the reliability and stability of the self-locking mechanism.

[0055] Please continue reading. Figure 5 and Figure 6 In an optional embodiment, the locking tongue 04 includes a locking portion for engaging with the side groove 07 of the power bank 06; a guide arc surface 18 is provided on the side of the locking portion facing the insertion direction of the power bank 06; a locking plane 19 is formed on the side of the locking portion facing away from the insertion direction of the power bank 06, the locking plane 19 is used to abut against the side wall of the groove 07, and the locking plane 19 is perpendicular to the insertion direction of the power bank 06.

[0056] The engaging portion at the front end of the latch 04 specifically includes a guide arc surface 18 and a locking plane 19, wherein the guide arc surface 18 is located on the side of the engaging portion facing the insertion direction of the power bank 06. This guide arc surface 18 can guide the side of the power bank 06 to smoothly press against the latch 04 when the power bank 06 is inserted, so that the latch 04 can retract smoothly, reducing insertion resistance and improving the user experience.

[0057] The locking plane 19 is located on the side of the engaging portion facing away from the insertion direction of the power bank 06. This locking plane 19 is designed to be strictly perpendicular to the insertion direction of the power bank 06. When the locking tongue 04 is engaged in the groove 07 of the power bank 06, this vertical locking plane 19 completely fits and abuts against the vertical side wall inside the groove 07.

[0058] This ensures that the locking force is directly transmitted along the axis of the power bank 06, avoiding the component force that would cause the locking tongue 04 to rotate or disengage due to the tilt of the contact surface, making the locking more secure and reliable in daily use.

[0059] A second aspect of this application provides an embodiment of a power bank 06 cabinet, which includes... Figures 1 to 5 Locking chamber structure of any of the embodiments.

[0060] The power bank 06 cabinet in this embodiment mainly includes: a cabinet frame, a control and power supply module, a human-machine interaction panel, and at least one locking compartment module.

[0061] The cabinet frame is made of metal profiles and plates, forming an external support structure to protect the internal locking compartment structure and other components, and to define the overall appearance.

[0062] The control and power supply modules are centrally located at the top or back of the cabinet, including the main control circuit board, network communication module, power conversion module, etc., and are responsible for handling the rental logic, communication, and providing unified power supply and control for the drive components of each locking compartment.

[0063] The human-computer interaction panel is located on the front of the cabinet and includes a display screen, a QR code scanning window, indicator lights, etc., providing users with an operating interface.

[0064] Each charging compartment 01 of the locking structure is fixedly installed on a pre-set mounting beam or bracket inside the cabinet frame by screws or clips. After installation, the insertion and removal ports of the two chambers 03 in each row on the charging compartment 01 face the front of the cabinet (i.e., the user operation surface) so that the user can insert and remove the power bank 06.
