[0024] Example 1: Refer to Figures 1-5A lightweight, detachable battery mounting structure for an electric-assist bicycle includes: a fixed housing 1 fixed to the electric-assist bicycle; a plug 102 disposed at the bottom of the fixed housing 1; a sliding housing 2 slidably disposed within the fixed housing 1, with its end sealed to the end of the fixed housing 1; a groove 105 on one side of the fixed housing 1; and a protrusion 204 corresponding to the groove 105 on one side of the sliding housing 2; a battery pack 3 slidably disposed within the sliding housing 2, with a socket 301 corresponding to the plug 102 at its lower end; a handle 201 disposed at the top of the sliding housing 2; and a fixing component for fixing the sliding housing 2 to the fixed housing 1, disposed on the sliding housing 2.
[0025] The fixing component includes a through groove 203 on the sliding box 2, and a fixing groove 104 corresponding to the through groove 203 on the fixing box 1. A positioning plate 207 is rotatably disposed in the through groove 203. A knob 208 is disposed on the sliding box 2 and is fixedly connected to the positioning plate 207. When the end of the positioning plate 207 rotates into the fixing groove 104, the positioning plate 207 limits the sliding box 2.
[0026] The fixed box 1 is symmetrically provided with limit grooves 103, and the sliding box 2 is symmetrically provided with limit blocks 202 corresponding to the limit grooves 103 on both sides.
[0027] The battery pack 3 is provided with a square groove 302, and a handle 303 is fixedly connected inside the square groove 302.
[0028] The positioning plate 207 is symmetrically provided with transition fillets 209.
[0029] By setting a transition fillet 209 on the positioning plate 207, it is easier for the positioning plate 207 to enter the fixing groove 104.
[0030] When it is necessary to disassemble the battery pack 3, turn the knob 208 to rotate the positioning plate 207 out of the fixing groove 104, release the limit on the sliding box 2, pull out the sliding box 2 by holding the handle 201, and then pull out the battery pack 3 by holding the handle 303. Then reset the sliding box 2, turn the knob 208 to make the positioning plate 207 enter the fixing groove 104 for limiting, thereby effectively solving the problem that the exposed cavity of the battery pack 3 is prone to water ingress in rainy weather after being removed, and avoiding water ingress from affecting the normal operation of the battery pack 3.
[0031] When installing the battery pack 3, first rotate the knob 208 to slide the positioning plate 207 out of the fixing groove 104, pull out the sliding box 2, then put the battery pack 3 into the sliding box 2, put the sliding box 2 into the fixing box 1, and under the action of gravity, the plug 102 is inserted into the socket 301. Using the built-in plug 102 can improve the stability of the connection between the plug 102 and the socket 301.
[0032] Example 2: Refer to Figures 1-5 A lightweight detachable battery mounting structure for an electric-assist bicycle is basically the same as that in Embodiment 1. Further, a support rod 101 is symmetrically fixedly connected to the bottom of the fixed box 1. When the plug 102 is inserted into the socket 301 of the battery pack 3, a first gap 304 is provided between the battery pack 3 and the lower end of the sliding box 2. A clamping block 205 corresponding to the battery pack 3 is symmetrically fixedly connected inside the sliding box 2. A guide angle 206 is provided at the upper end of the clamping block 205.
[0033] When installing battery pack 3, battery pack 3 first enters the sliding housing 2, and then enters between the two clamping blocks 205 under the action of gravity, which limits the battery pack 3, thereby improving the accuracy of the connection between plug 102 and socket 301. Furthermore, by positioning battery pack 3 through the two clamping blocks 205, the friction between battery pack 3 and sliding housing 2 can be reduced, making it easier to remove battery pack 3.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
