During installation, the sliding plate is pulled to drive the limiting rod downward into the fixing frame and squeeze the spring, so as to push the battery management device into place inside the base, release the sliding plate, and the spring rebounds to push the sliding plate and the limiting rod upward. The limiting rod passes through the limiting hole, so that the battery management device can be limited and fixed inside the base, and installation and disassembly of the battery management device is convenient.

[0027] Figure 1-4 The structure diagram of a combined battery management module embodiment of the utility model is shown. Figure 1-Figure 4 A combined battery management module of this embodiment includes a battery management device body 100, a base 200, and limiting components 300 and 400.

[0028] A fixing plate 110 is installed on the top of the symmetrical side wall of the battery management device body 100, and a limiting hole 120 is opened on the top of the fixing plate 110. The size of the battery management device body 100 is the same as the internal size of the base 200. When the battery management device body 100 is located inside the base 200, the outer wall of the battery management device body 100 fits with the inner wall of the base 200.

[0029] A slide groove 210 is provided at the front end of the top of the base 200, the fixing plate 110 is located inside the slide groove 210, a T-slot 220 is provided at the bottom of the base 200, a T-slot 130 matching the T-slot 220 is installed at the corresponding position of the bottom of the battery management device body 100 and the T-slot 220, a mounting plate 230 is installed on the symmetrical side wall of the base 200, a screw hole 231 is provided on the top of the mounting plate 230, a buffer plate 240 is slidably connected inside the base 200, a first spring 241 is installed on the side wall of the buffer plate 240, and the other end of the first spring 241 is connected to the inner wall of the base 200, The symmetrical side walls of the base 200 are provided with guide grooves 250, and the symmetrical side walls of the buffer plate 240 are provided with guide plates 242, which extend into the guide grooves 250. The side walls of the base 200 are provided with air grooves 260, and the top of the base 200 is provided with air holes 261 connected to the air grooves 260. A piston 270 is provided inside the air grooves 260, and a connecting rod 271 is installed on the side wall of the piston 270. The other end of the connecting rod 271 is connected to the side wall of the buffer plate 240. When the battery management device body 100 moves toward the inside of the base 200, the fixing plate 110 slides inside the slide groove 210, limiting the movement of the fixing plate 110. The positioning hole 120 slides inside the T-slot 220, and the T-slot 220 limits the battery management device body 100 in the up, down, left, and right directions until the side wall of the battery management device body 100 abuts against the side wall of the buffer plate 240. As the battery management device body 100 continues to move into the base 200, the battery management device body 100 pushes the buffer plate 240 to move into the base 200 and squeezes the first spring 241. The guide plate 242 slides inside the guide groove 250. At the same time, when the buffer plate 240 slides into the base 200, it pushes the piston 270 to slide into the air groove 260. The air in the air groove 260 is squeezed out from the air hole 261 until the battery management device body 100 is completely retracted into the base 200. When the base 200 is removed, the first spring 241 rebounds and pushes the buffer plate 240 and the battery management device body 100 to move outside the base 200. The buffer plate 240 pulls the piston 270 to move outside the air groove 260. External air enters the air groove 260 through the air hole 261. The air pressure is used to reduce the rebound speed of the first spring 241, so that the buffer plate 240 slowly moves the battery management device body 100 to the outside of the base 200.

[0030] The limiting assembly 300 includes a fixed frame 310 installed on the side wall of the battery management device body 100, a slide plate 320 slidably connected to the inside of the fixed frame 310, a second spring 330 installed at the bottom of the slide plate 320, and a limiting rod 340 installed at the top of the slide plate 320. The limiting rod 340 extends through the top of the fixed frame 310 and passes through the limiting hole 120. When the battery management device body 100 is installed, the slide plate 320 is pulled to drive the limiting rod 340 to move into the inside of the fixed frame 310 and squeeze the second spring 330 until the limiting rod 340 is retracted into the inside of the fixed frame 310. At this time, the battery management device body 100 is pushed to insert into the base 200, and the slide plate 320 is released. The second spring 330 rebounds and pushes the slide plate 320 and the limiting rod 340 to move upward. The limiting rod 340 passes through the limiting hole 120 to limit and fix the battery management device body 100 inside the base 200.

[0031] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
