[0022] The present utility model will be further described below with reference to the embodiments.

[0023] Embodiment: Refer to Figures 1 to 5 , a structure of a mine-explosion-proof lithium-ion locomotive, including a locomotive body 1 and a mounting box 2. The mounting box 2 is installed inside the locomotive body 1. Cross slots 4 are provided on both inner walls of the mounting box 2. A first buffer mechanism is arranged inside the cross slots 4. A second buffer mechanism is arranged at the bottom of the mounting box 2. A top cover 5 is arranged at the top of the mounting box 2. A limiting mechanism is arranged at the bottom of the top cover 5. Under the action of the first buffer mechanism, the second buffer mechanism and the limiting mechanism, when the locomotive body 1 collides with an obstacle or the mine wall surface, it may cause damage to the storage battery 7, and further may cause the storage battery 7 to explode, posing a great threat to the safe production of the mine.

[0024] Specifically, refer to Figures 4 to 5 , the first buffer mechanism includes a cross rod 8. The cross rod 8 is slidably installed inside the cross slot 4. A fixed cylinder 9 is fixedly connected to the side wall of the cross rod 8. A spring 10 is fixedly connected inside the fixed cylinder 9. The other end of the spring 10 is fixedly connected to a connecting column 11. The connecting column 11 is slidably connected to the fixed cylinder 9. A limiting plate 12 is fixedly connected to the end of the connecting column 11 away from the spring 10. With the cooperation of the two first buffer mechanisms, it is convenient to protect both sides of the storage battery 7, avoiding the situation that may affect both sides of the storage battery 7 during collision, resulting in a short circuit of the storage battery 7 and possibly causing an explosion.

[0025] Further, referring to Figure 4 , the second buffer mechanism includes two shock-absorbing springs 17. The bottom ends of the shock-absorbing springs 17 are fixedly connected to the inner bottom wall of the mounting box 2. The top of the shock-absorbing spring 17 is fixedly connected with a mounting plate 18, and the width specification of the mounting plate 18 is the same as that of the mounting box 2. A storage battery 7 is arranged inside the mounting box 2, and the storage battery 7 is located above the mounting plate 18. The top and bottom of the storage battery 7 are cooperated with the top plate 13 to prevent the storage battery 7 from being affected when a collision occurs, and thus an explosion may occur.

[0026] Further, referring to Figure 3 , the limiting mechanism includes a top plate 13. The top plate 13 is fixedly installed at the bottom of the top cover 5. Cross-shaped blocks 6 are fixedly connected to both sides of the top plate 13. The cross-shaped blocks 6 are clamped with the cross-shaped grooves 4 to limit the top of the storage battery 7, thereby reducing the impact on the storage battery 7 during a collision.

[0027] Further, referring to Figure 2 , multiple groups of heat dissipation holes 3 are arranged on both side walls of the mounting box 2. The multiple groups of heat dissipation holes 3 are arranged opposite to each other respectively, which is convenient for heat dissipation.

[0028] Further, referring to Figure 1 , a moving wheel 15 is arranged inside the motor vehicle body 1. A car door 16 is arranged on the side wall of the motor vehicle body 1. An observation window 14 is arranged on the side wall of the motor vehicle body 1, which is convenient for the staff to use the motor vehicle body 1 and observe the road conditions in front of the motor vehicle body 1.

[0029] The working principle of the present utility model is as follows:

[0030] Take two cross-shaped rods 8 and install the two cross-shaped rods 8 inside the two cross-shaped grooves 4 respectively. When installing the cross-shaped rod 8 inside the cross-shaped groove 4, first pull one of the limiting plates 12, then the limiting plate 12 has a certain acting force on the connecting column 11, and the connecting column 11 has an acting force on the spring 10 inside the fixed cylinder 9, causing the spring 10 to deform. Place the storage battery 7 inside the mounting box 2, then make the two limiting plates 12 limit the two sides of the storage battery 7, then adjust the position of the storage battery 7, and at the same time place the storage battery 7 on the mounting plate 18, which has a certain acting force on the shock-absorbing spring 17, causing the shock-absorbing spring 17 to deform. Finally, cover the top cover 5 on the top of the mounting box 2, then the top plate 13 limits the top of the storage battery 7, and at the same time the cross-shaped block 6 extends into the cross-shaped groove 4 to limit the cross-shaped rod 8. If a collision occurs, under the action of the spring 10 and the shock-absorbing spring 17, it has a certain protective effect on the storage battery 7, preventing the storage battery 7 from being damaged due to the collision between the motor vehicle body 1 and an obstacle or the mine wall surface, causing a fire and resulting in an explosion of the storage battery 7, affecting the safe operation in the mine.
