[0020] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings, wherein the same parts are represented by the same reference numerals.

[0021] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0022] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0023] like Figures 1 to 4 As shown, an improved battery box includes a box body 1, an upper cover 2 is inserted into the upper end of the box body 1, a handle 27 is installed on the upper end of the upper cover 2, and the box body 1 is pulled conveniently by the handle 27, two positioning rods 23 are symmetrically installed at the lower end of the upper cover 2, and a positioning groove 24 used in conjunction with the positioning rod 23 is installed at the bottom end of the box body 1. The positioning rod 23 is inserted into the positioning groove 24, so that the upper cover 2 and the box body 1 are aligned and installed, and a through hole is provided at the bottom end of the box body 1, and the position of the through hole corresponds to the positioning groove 24. A bolt 25 is installed inside the through hole, and the bolt 25 is threadedly connected to the lower end of the positioning rod 23 to fix the positioning rod 23, thereby fixing the upper cover 2 to the upper end of the box body 1, and a sealing plug 26 is installed in the through hole to protect the bolt 25 from being exposed to the air.

[0024] A bracket 6 is fixedly installed in the middle of the base inside the box body 1. The bracket 6 is H-shaped. The bracket 6 includes two vertical bars and a horizontal bar. The horizontal bar can slide up and down between the two vertical bars. A placement groove 7 is fixedly installed on the upper end of the bracket 6. The battery module 8 is located inside the placement groove 7. A buffer airbag 28 is installed at the lower end of the bracket 6. A vibration reduction structure 9 is installed on both sides of the lower end of the placement groove 7. When the train generates vibration during operation, the vibration reduction structure 9 and the buffer airbag 28 can protect the battery module 8.

[0025] The vibration reduction structure 9 includes a fixed frame 10, which is fixedly installed at the bottom end of the box body 1. A spring 11 is symmetrically installed at the bottom end of the fixed frame 10. A movable plate 12 is installed at the upper end of the spring 11. The movable plate 12 can slide up and down inside the fixed frame 10. A slide rod 13 is installed at the upper end of the movable plate 12. The slide rod 13 passes through the upper end of the fixed frame 10. The slide rod 13 can slide. A damper 15 is installed at the upper end of the slide rod 13. The damper 15 is connected to the bottom end of the placement groove 7. A spring 2 14 is installed on the surface of the slide rod 13. The spring 2 14 is located between the fixed frame 10 and the damper 15.

[0026] When vibration occurs, the placement slot 7 drives the slide bar 13 to move, and the slide bar 13 drives the spring 11 to compress or stretch through the movable plate 12, and at the same time stretches or compresses the spring 2 14. The damper 15 can absorb the elastic potential energy of the spring 11 and the spring 2 14, so that the vibration tends to be smooth, thereby protecting the battery module 8.

[0027] The two ends of the box body 1 are connected to a buffer structure 4, which can protect the box body 1 when the box body 1 is hit. The buffer structure 4 includes a connecting plate 16, which is U-shaped. Both ends of the connecting plate 16 are threadedly connected to the outer end of the box body 1, and the connecting plate 16 can be disassembled and installed. Two connecting blocks 17 are symmetrically installed at one end of the connecting plate 16, and a rotatable support rod 18 is installed inside the connecting block 17. Two stoppers 19 are symmetrically installed at one end of the buffer plate 3 close to the box body 1, and a guide rod 20 is installed between the two stoppers 19. A slider 21 is mounted on the surface of the guide rod 20, and the slider 21 can slide on the surface of the guide rod 20. There are two sliders 21, and the other end of the support rod 18 is hinged to the slider 21. A spring three 22 is installed between the two sliders 21, and the spring three 22 is mounted on the surface of the guide rod 20, and the spring three 22 plays a buffering role.

[0028] When the buffer plate 3 is hit by an external force, the buffer plate 3 moves closer to the box body 1, so that the support rod 18 rotates inside the connecting block 17 and the slider 21, thereby driving the two sliders 21 to move closer to each other, thereby compressing the spring three 22, which can buffer the impact and avoid the impact force directly acting on the outer end of the box body 1, thereby improving the safety of the battery module 8 inside the box body 1.

[0029] Heat dissipation holes 5 are installed at the other two ends of the box body 1. Dust-proof nets and heat dissipation fans are installed at the heat dissipation holes 5 to facilitate gas exchange inside and outside the box body 1 and prevent excessive temperature from affecting the use of the battery module 8.

[0030] During specific use, the upper cover 2 is clamped on the upper end of the box body 1, the positioning rod 23 is inserted into the positioning groove 24, the positioning rod 23 is fixed by the bolt 25, and the sealing plug 26 is inserted into the through hole. Heat is dissipated through the heat dissipation hole 5. When the box body 1 is subjected to external impact, the buffer plate 3 approaches the box body 1, so that the support rod 18 rotates inside the connecting block 17 and the slider 21, thereby driving the two sliders 21 to move closer to each other, thereby compressing the spring three 22, which can buffer the impact.

[0031] When vibration is generated during the operation of the train and is transmitted to the box body 1, the placement slot 7 drives the slide bar 13 to move, and the slide bar 13 drives the spring 11 to be compressed or stretched through the movable plate 12, and at the same time stretches or compresses the spring 2 14. The damper 15 can absorb the elastic potential energy of the spring 11 and the spring 2 14, so that the vibration tends to be smooth, thereby protecting the battery module 8.

[0032] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
