[0025] A quick-release locking structure for electric wheelchair batteries, used for the quick and safe installation and removal of battery components in electric wheelchairs.

[0026] Reference Figure 1 and Figure 2 The quick-release locking structure for the battery includes a battery compartment 1 and a battery assembly. The battery compartment 1 is mounted on the frame of the electric wheelchair, forming a cavity with an upward opening, allowing the battery assembly to be installed downward into the battery compartment 1.

[0027] Reference Figure 3 and Figure 4 As shown, the battery assembly includes a battery body, a housing 21, and a cover plate 22. The housing 21 forms a square structure so that the battery body is placed inside the housing 21. The cover plate 22 covers the top of the housing 21 and is snapped and fixed to the housing 21 to close the housing 21 and isolate the internal battery body from the outside. A handle 23 is provided on the top of the cover plate 22 so that the user can directly pick up the entire battery assembly through the handle 23.

[0028] A window 26 is provided at the bottom of the outer casing 21. When the battery body is installed in the outer casing 21, the power interface of the battery body is facing the window 26. A power base 11 is provided at the bottom of the battery compartment 1. A blade-type connector is provided on the power base 11. When the battery assembly is installed in the battery compartment 1, the blade-type connector passes through the window 26 and connects with the power interface, so that the battery assembly supplies power to the electric wheelchair.

[0029] When the battery pack is installed into the battery compartment 1, the inner peripheral wall of the battery compartment 1 and the outer peripheral wall of the outer shell 21 form a clearance fit. The inner wall of the battery compartment 1 is provided with a guide rib 13 protruding outwards, and the corresponding outer shell 21 is provided with a guide groove 24 for cooperating with the guide rib 13, thereby guiding the installation direction of the battery pack and ensuring the correct connection between the power interface and the blade-type connector.

[0030] The power base 11 protrudes from the bottom of the battery compartment 1, so that the position of the blade-type connector is at a set height from the bottom of the battery compartment 1. When water enters the battery compartment 1, as long as the water level at the bottom of the battery compartment 1 does not exceed the set height, it will not come into contact with the blade-type connector and cause a risk. Furthermore, a drain hole 12 is also provided at the bottom of the battery compartment 1. The drain hole 12 is set downward to drain the water at the bottom of the battery compartment 1 in a timely manner.

[0031] A locking mechanism is also provided on one side of the battery compartment 1, see reference. Figure 5 The locking assembly includes a pressing block 31, a spring 34, and a pivot pin 32. The pressing block 31 is hinged to the outside of the battery compartment 1, allowing the pressing block 31 to rotate within a set range. The inner wall of the battery compartment 1 has a through hole 33 for the pivot pin 32 to pass through. One end of the pivot pin 32 extends into the battery compartment 1, and the other end is hinged to the pressing block 31. The spring 34 is coaxially sleeved on the outside of the pivot pin 32, and both ends of the spring 34 are connected to the pivot pin 32 and the inner wall of the through hole 33, respectively, so that the movement of the pivot pin 32 drives the movement of the spring 34. The outer shell 21 or the cover plate 22 is provided with an insertion hole 25 for the pivot pin 32 to be inserted.

[0032] When no other external force is applied, one end of the axle pin 32 extends into the battery compartment 1. When the battery assembly is installed in place with the battery compartment 1, one end of the axle pin 32 is inserted into the socket 25, thereby locking the battery assembly and making the battery assembly stable in the battery compartment 1, preventing it from shaking and effectively preventing it from falling off on bumpy roads.

[0033] When the pressing block 31 is pushed to rotate, the action of the pressing block 31 causes the shaft pin 32 to move, causing the end of the shaft pin 32 to disengage from the socket 25, releasing the lock on the battery assembly, allowing the user to remove the battery assembly. When the pressing block 31 is released, the spring 34 drives the shaft pin 32 to reset, allowing the shaft pin 32 to be locked again.

[0034] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort should fall within the protection scope of this utility model.
