[0015] 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.

[0016] Reference Figures 1 to 4, a long module side pressure plate fixing structure, including a plurality of brackets 10, a pressure plate 2, an L-shaped plate 3, a support plate 4 and a spring 5, each of which is a group of two brackets 10 and are spaced from each other and detachably connected to the main beam in the battery box, the L-shaped plate 3 is arranged on the bracket 10, the support plate 4 can be slidably arranged on the L-shaped plate 3 up and down, a plurality of springs 5 ​​are arranged between the bracket 10 and the support plate 4, a plurality of slots 201 are arranged on both sides of the pressure plate 2, a plurality of protrusions 301 are arranged on the L-shaped plate 3, two ends of one side of the pressure plate 2 are respectively inserted between the L-shaped plate 3 and the support plate 4 and the protrusions 301 can cooperate with the slots 201, and the other side of the pressure plate 2 abuts against the upper end surface of one side of the module. In the utility model, when in use, first fix a number of brackets 10 on the main beam in the battery box, and set them in intervals in a group of two. After the module is put into the box, give the support plate 4 a downward force to make it move downward and squeeze the spring 5, and pass the pressure plate 2 through the gap between the L-shaped plate 3 and the support plate 4. The spring 5 gives the support plate 4 a reaction force to clamp the pressure plate 2. At the same time, the protrusion 301 cooperates with the slot 201 to fix the pressure plate 2 so that it will not move. The other side of the pressure plate 2 contacts the side of the module to prevent the module from moving upward due to vibration. Two groups of pressure plates 2 are used on one side of the module, which greatly increases the strength of the side of the module and meets the safety of battery driving. Specifically, the bracket 10 and the support plate 4 are provided with a number of grooves, and the two ends of the spring 5 are respectively arranged in the grooves on the bracket 10 and the support plate 4.

[0017] As a preferred embodiment of the utility model, it may also have the following additional technical features:

[0018] In this embodiment, a slide groove 302 is provided on one side of the L-shaped plate 3, and a T-shaped slide rod 401 is provided on one side of the support plate 4. The slide rod 401 can slide in the slide groove 302, and the slide rod 401 can move up and down in the slide groove 302. The support plate 4 can move up and down, which makes it convenient for the pressure plate 2 to be inserted between the L-shaped plate 3 and the support plate 4, and also convenient for taking it out.

[0019] In this embodiment, the bracket 10 is a sheet metal bracket in a U shape, which reduces the weight of the bracket 10 and further reduces the weight of the entire battery box.

[0020] In this embodiment, a reinforcing plate 101 is provided on the bracket 10 to improve the strength of the bracket 10. Specifically, the reinforcing plate 101 is a sheet metal part.

[0021] In this embodiment, ear plates 102 are provided on both sides of the bracket 10. The ear plates 102 are provided with through holes. Bolts pass through the through holes on the ear plates 102 to connect with the main beam in the battery box, thereby fixing the bracket 10 on the main beam.
