Detailed Implementation

[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0021] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0022] like Figures 1 to 4As shown in the figure, a specific embodiment of this utility model provides an electric wheelchair power supply installation device, mainly composed of two parts: a power supply frame 100 fixed on the wheelchair frame and a power supply housing 200 with a built-in power supply module. This device has advantages such as high ease of installation and disassembly, and high stability. Specifically, it includes a power supply frame 100 fixed on the wheelchair frame and a power supply housing 200 with a built-in power supply module. The power supply frame 100 has a fixing part 110 and a limiting part 120 respectively on its outer side corresponding to both ends of the power supply housing 200. The lower surface of the fixing part 110 has a fixing slot 111. The lower end of the power supply housing 200... The power supply housing 200 is provided with a limiting groove 210 that fits into the limiting part 120. The upper end of the power supply housing 200 is provided with a locking block 300 that can slide up and down. The lower end of the locking block 300 is provided with inclined sliding grooves 310 on the opposite side walls. The outer side of the power supply housing 200 is also provided with an unlocking button 400. The lower end of the unlocking button 400 slides in cooperation with the sliding groove 310. The power supply housing 200 is provided with an elastic element that elastically supports the unlocking button 400, so that the upper end of the locking block 300 can be inserted into the fixed slot 111. When the unlocking button 400 is pressed, the locking block 300 can slide down and separate from the fixed slot 111.

[0023] like Figures 1 to 4 As shown, with the above configuration, in this embodiment, the power supply module for power supply is installed inside the power supply housing 200, and the power supply frame 100 is installed on the wheelchair frame. The outer side of the power supply frame 100 is provided with a fixing part 110 and a limiting part 120 respectively corresponding to both ends of the power supply housing 200. The locking mechanism realizes the stable connection and convenient disassembly of the power supply housing 200 and the power supply frame 100. During installation, one end of the power supply housing 200 engages with the limiting part 120 via the limiting groove 210, while the other end is supported by the locking block 300 via an elastic element, causing its upper end to engage with the fixing slot 111 of the power supply frame 100. After both ends of the power supply housing 200 are fixed, the stability of the installation of the power supply housing 200 is ensured, preventing the power supply from falling off due to the bumps caused by wheelchair movement.
