DETAILED DESCRIPTION

[0019] In order to facilitate the understanding of the present invention, the present invention is described more comprehensively with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. The purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0020] Refer to the attached Figures 1 to 6 As shown, a quick-release battery box in this embodiment is suitable for an electric wheelchair, comprising a battery installation compartment 1 fixedly connected to the frame of the electric wheelchair, a battery body 2 placed in the battery installation compartment 1, and at least one self-locking device 3 is used to stop and limit the battery installation compartment 1 and the battery body 2; wherein, in this embodiment, two symmetrically arranged self-locking devices 3 are provided, each of which comprises a locking pin 31, a button 32 provided on the outer peripheral surface of the battery installation compartment 1, and a reset spring 33. It should be noted here that the position and size of the compartment opening of the battery installation compartment 1 are set according to actual production needs; and in this embodiment, the position of the compartment opening of the battery installation compartment 1 is set at the upper end of the compartment body for industrial production and assembly, and the specifications of the battery body 2 are adapted to the compartment opening of the battery installation compartment 1 (that is, the battery body 2 matches the shape of the battery installation compartment 1, and the specifications of the battery body 2 are slightly smaller than or equal to the size of the compartment opening of the battery installation compartment 1) so that the battery body 2 can be smoothly placed into the battery installation compartment 1 from the compartment opening and close to the inner wall of the compartment body.

[0021] Specifically, in this embodiment, the battery installation compartment 1 is formed with a sliding cavity 11 extending along the thickness direction of the compartment body and penetrating the compartment body, and the outer peripheral surface of the battery body 2 is preformed with a lock hole 21 at a position relative to the exit of the sliding cavity 11. More specifically, the lock pin 31 is slidably inserted into the sliding cavity 11, and the inner side end of the lock pin 31 passes through the sliding cavity 11 and is inserted into the lock hole 21, and the lock pin 31 and the inner wall of the lock hole 21 are in contact with each other to achieve the locking limit between the battery body 2 and the battery installation compartment 1; secondly, the outer side end of the lock pin 31 is limitedly embedded in the key cavity 34 at one end of the button 32, and the return spring 33 is sleeved in the key cavity 34 at the other end of the button 32 to limit its movement. By pressing the button 32 (i.e., the other end with the return spring 33), the end with the lock pin 31 is tilted outward, thereby driving the lock pin 31 to escape from the lock hole 21 to release the locking limit between the battery body 2 and the battery installation compartment 1.

[0022] In this way, the battery body 2 and the battery installation compartment 1 can be easily and quickly disassembled and assembled, and the battery box can be easily replaced and maintained. When the battery body 2 is low in power, the battery body 2 with low power can be replaced with a battery body 2 with high power through a replacement operation, so that the electric wheelchair is instantly in a fully charged state and continues to be used by the user, and the battery body 2 with low power can be charged independently, which effectively solves the problem that the electric wheelchair cannot be moved at will during charging, greatly reduces the charging waiting time, and greatly improves the user experience.

[0023] Furthermore, in order to facilitate the battery body 2 to slide smoothly from the hatch into the battery installation compartment 1 and quickly achieve locking, the outer peripheral surface of the battery body 2 in this embodiment is formed with a slide groove 22 extending toward the lock hole 21, and the inner end surface of the slide groove 22 gradually tilts inward toward the lock hole 21 to form a contact slope 221 so that the inner side end of the lock pin 31 slides relatively along the slide groove 22. When the battery body 2 slides in from the hatch, the slide groove 22 plays a certain guiding role, and the inner side end of the lock pin 31 slides relatively along the slide groove 22 and then slides into the lock hole 21 and is stopped and limited. At this time, the battery body 2 cannot move under the tightening action of the lock pin 31, thereby achieving the effect of quickly locking the battery body 2 and the battery installation compartment 1.

[0024] Furthermore, in order to facilitate industrial production and assembly, the outer peripheral surface of the battery mounting compartment 1 in this embodiment is protruded with at least one button seat 12; wherein, the button 32 is fixedly connected to the button seat 12 by a limiting rod 35 vertically penetrating and connecting the button seat 12 and the button 32, one end of the return spring 33 is connected to the inner wall of the button seat 12, and the inner cavity on one side of the button seat 12 is connected to the sliding cavity 11 so that the locking pin 31 can be smoothly inserted into the sliding cavity 11; thereby, each self-locking device 3 is relatively restricted by the inner cavity of the corresponding button seat 12 to avoid displacement of the self-locking device 3.

[0025] In this embodiment, in order to facilitate the user to replace the battery body 2, a handle 5 is provided on the top surface of the battery body 2 for the user to take. When performing the replacement operation, press the button 32, and then pull the handle 5 to pull the battery body 2 out of the battery installation compartment 1. In addition, at least one charging interface 6 for charging the battery body 2 is provided on the top surface of the battery body 2, and at least one discharge interface 7 is provided on the outer peripheral surface of the battery body 2, and a discharge line can be led out at the discharge interface 7 for the user to use. It should be noted here that in order to ensure safety in use, when using the charging interface 6, the discharge interface 7 needs to be covered with an insulating cover; when using the discharge interface 7, the charging interface 6 needs to be covered with an insulating cover.

[0026] The embodiments described above are only preferred embodiments of the present invention and do not limit the present invention in any form. Any technician familiar with the field, without departing from the scope of the technical solution of the present invention, can make more possible changes and modifications to the technical solution of the present invention using the technical content disclosed above, or the modifications are equivalent embodiments of the present invention. Therefore, any equivalent and equivalent changes made according to the idea of ​​the present invention without departing from the content of the technical solution of the present invention should be included in the protection scope of the present invention.
