DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] To solve the problem that most existing battery modules of different sizes need to be matched with corresponding fixing structures, which makes the universality of the battery module fixing structure slightly insufficient, please refer to Figure 1-Figure 5 The utility model provides an embodiment: by placing the battery body 1 on the unfolded bottom bracket assembly 2, and then utilizing the adjustability of the position of the limiting assembly 4 on the guide rail assembly 3, as well as the adjustability of its own height and width, the limiting assembly 4 can be adapted to fix battery bodies 1 of various specifications and sizes, thereby effectively improving its adaptability.

[0022] A battery assembly that is easy to fix, comprising a battery body 1, and a bottom bracket assembly 2 arranged at the bottom of the battery body 1, guide rail assemblies 3 are installed on both sides of the top of the bottom bracket assembly 2, and limit assemblies 4 are slidably sleeved on the two guide rail assemblies 3. The top of the battery body 1 is provided with an embedded groove adapted to the limit assemblies 4, and the limit assembly 4 includes a slide seat 401 slidably sleeved on the two guide rail assemblies 3, and a connecting column 402 is fixedly installed between the inner walls on both sides of the top of the two slide seats 401, and the outer surfaces of the two connecting columns 402 are rotatably sleeved with side rods 403, and the top of the side rods 403 A circular groove is opened in the part, and a limiting plate 404 is arranged above the two side rods 403. A telescopic spring 405 is fixedly connected between the bottom of the limiting plate 404 and the bottom wall of the circular groove. One side of the two side rods 403 is threadedly connected with a side pressing structure 406. A through-slot plate is fixedly installed on the outer side of the bottom of the limiting component 4, and a plurality of spring buttons are installed on the top of the guide rail component 3, and the top of one of the spring buttons extends into the interior of the through-slot plate. The side pressing structure 406 consists of a threaded rod and a pressing plate, and the pressing plate is fixedly installed on one side of the threaded rod, and one side of the pressing plate is in contact with the outer surface of the battery body 1.

[0023] In this embodiment, the limiting assembly 4 is combined with the guide rail assembly 3, and then the base assembly 2 and the guide rail assembly 3 are adjusted to the expanded state. At this time, the distance between the two limiting assemblies 4 on the guide rail assembly 3 is adjusted to be larger than the length of the battery body 1 to be fixed, and the distance between the two side pressing structures 406 in the limiting assembly 4 is also larger than the width of the battery body 1. Then the battery body 1 is placed on the top surface of the base assembly 2. On this basis, an upward pulling force is applied to the limiting plates 404 in the two limiting assemblies 4, and the telescopic springs 405 are stretched outward by the pulling force, so that the distance between the bottom of the limiting plate 404 and the top of the base assembly 2 is adjusted to be larger than the height of the battery body 1, and the two limiting plates are pushed. The positioning assembly 4 moves in the opposite direction along the outer surface of the guide rail assembly 3, and at the same time, the spring buttons are pressed downward one by one until the position of the limiting plate 404 is adjusted to the top of the top embedded groove in the battery body 1, and when the spring button at the set position matching the size specification of the battery body 1 extends upward to the inside of the through-slot plate, the position of the slide seat 401 on the guide rail assembly 3 can be limited. In addition, the external force applied to the limiting plate 404 is canceled. Under the elasticity and reset of the telescopic spring 405 itself, the limiting plate 404 moves downward into the embedded groove, and then the side pressing structure 406 is rotated in sequence to make its pressing plate fit the outside of the battery body 1, so as to achieve the purpose of fixing the battery body 1 and the bottom bracket assembly 2.

[0024] Specifically, by moving the side rod 403 to rotate along the outer surface of the connecting column 402, the structure formed by the side rod 403, the telescopic spring 405 and the limit plate 404 can be adjusted between the vertical state and the horizontal state. When it is in a state parallel to the guide rail assembly 3, the overall occupied space can be effectively reduced.

[0025] See also Figure 1 , Figure 2 and Figure 4 , an embodiment provided by the utility model;

[0026] The bottom support assembly 2 includes two bottom support plates 201 arranged in a front-to-back mirror image and movably connected at the bottom by hinges. A groove 202 is provided on the top of the opposite side of the two bottom support plates 201. A T-shaped buckle 203 is fixedly installed on the bottom wall of one of the grooves 202. An adjustment card plate 204 is rotatably sleeved on the outer surface of the buckle 203, and half of the width of the adjustment card plate 204 is less than the distance between the center of the buckle 203 and the back of the bottom support plate 201. The guide rail assembly 3 includes a slide rail 301 fixedly installed on one side of the top of the bottom support plate 201 and arranged in a T shape. The number of the slide rails 301 is two, and the two The connection point of the slide rail 301 and the connection point of the two bottom support plates 201 are on the same cross-sectional plane. The guide rail assembly 3 also includes a slot 302 opened on one side of one of the slide rails 301. Rectangular slots are opened at opposite ends of the two slide rails 301, and one of the rectangular slots is connected to the slot 302. A spring member 303 is threadedly connected to the rear wall of one of the rectangular slots. A plug-in rod 304 is connected to one end of the spring member 303, and one end of the plug-in rod 304 extends into the interior of the other rectangular slot. A shift block is fixedly installed on one side of the plug-in rod 304, and the shift block is slidably connected to the interior of the slot 302.

[0027] When the battery body 1 is not assembled, the structure in the present embodiment can be adjusted by toggling the card plate 204 to cause it to rotate 90° along the outer surface of the buckle 203, so that its bottom is adjusted from being in contact with the bottom walls of the two grooves 202 to being in contact with the bottom wall of only one of the grooves 202. In addition, a pushing force toward the rear side is applied to the plug-in rod 304 by the toggle block, so that the spring member 303 contracts inward, driving the plug-in rod 304 to gradually move away from the other slide rail 301, and then the unfolded bottom bracket assembly 2 can be folded in half to achieve the purpose of changing its shape. At the same time, the structure formed by the side rod 403, the telescopic spring 405 and the limit plate 404 is adjusted to be parallel to the guide rail assembly 3, which can save the space required for its transportation to a large extent.
