A fixing seat 13 is installed on the inner wall of the battery box body 9, and a battery body 10 is installed on the top of the fixing seat 13. Fixing plates 1 are installed on both sides of the battery body 10. A cover body 8 is installed above the battery box body 9, and a heat sink 7 is installed above the cover body 8. Air inlets 6 are arranged on both sides of the top of the heat sink 7, and fans 5 are installed on the inner sides of the air inlets 6.

[0021] A gear 12 is installed at the middle position of the inner wall of the fixing seat 13, and one end of the gear 12 is connected to a crank 14, and racks 11 are meshed and installed at both ends of the gear 12, and one end of the rack 11 is fixedly connected to the bottom end of the fixing plate 1;

[0022] The outer wall of the crank handle 14 is provided with a locking groove 15, and a locking rod 16 is installed inside the locking groove 15;

[0023] A damper 18 is installed on the inner wall of one end of the fixing seat 13, and a return spring 17 is installed on the outer wall of the damper 18, and one end of the return spring 17 is fixedly connected to the locking rod 16;

[0024] The inner walls at both ends of the fixing seat 13 are provided with limiting grooves, and the outer walls of the rack 11 are movably connected to the limiting grooves through limiting blocks;

[0025] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, when this structure is used, the gear 12 is rotated by rotating the crank 14, and the gear 12 is engaged with the racks 11 at both ends, so that the racks 11 at both ends drive the fixing plates 1 to move inward or outward at the same time, which is convenient for adjusting the spacing between the fixing plates 1, and can be clamped and fixed according to the size of the battery body 10, and has strong applicability.

[0026] Embodiment 2: A coolant pipe 4 is installed below the fan 5, and the front view of the coolant pipe 4 is formed by a combination of multiple "U"-shaped pipes;

[0027] The heat conducting plates 3 are evenly installed below the coolant pipes 4, and the heat absorbing blocks 2 are connected below the heat conducting plates 3;

[0028] Specifically, Figure 1 and Figure 2 As shown, when this structure is used, when the battery body 10 generates heat during operation, the heat is absorbed by the heat absorption block 2, and then the heat is transferred to the multiple heat conducting plates 3. The fan 5 then blows air to the coolant pipe 4, and the resulting cold air quickly cools the heat conducting plate 3, dissipating the heat inside the battery box body 9, thereby facilitating the heat dissipation of the battery body 10.

[0029] Working principle: When using the device, first install the battery body 10 in the battery box body 9, clamp and fix the battery body 10 through the fixing plate 1, and then fix the battery box body 9 in the car for installation;

[0030] The first step to implement the innovation point:

[0031] Step 1: Move the lock rod 16 to one side to keep it away from the lock slot 15, then rotate the crank 14 to rotate the gear 12, and the gear 12 is meshed with the racks 11 at both ends, so that the racks 11 at both ends drive the fixing plates 1 to move inward or outward at the same time, so as to adjust the spacing between the fixing plates 1, and the battery body 10 can be clamped and fixed according to the size of the battery body 10;

[0032] Step 2: After the position of the fixing plate 1 is fixed, the locking rod 16 is loosened to reset the damper 18 and the return spring 17, so that the locking rod 16 is inserted into the locking groove 15, thereby locking the position of the crank handle 14.

[0033] The second innovation point implementation steps:

[0034] Step 1: When the battery body 10 generates heat during operation, the heat is absorbed by the heat absorbing block 2, and then the heat is transferred to the multiple heat conducting plates 3;

[0035] Step 2: The fan 5 is operated to blow air to the coolant pipe 4, and the resulting cold air quickly cools the heat conducting plate 3, thereby dissipating heat inside the battery box body 9, extending the service life of the battery body 10 and ensuring the performance of the battery body 10.
