[0049] In particular, a wind guide plate 24 is fixedly installed in the wind guide chamber 38 to guide the natural wind and optimize the heat dissipation effect;

[0050] As shown in Figure 1 and Figure 2 It is to be noted that the perforated ventilation plates 13 in each of the wind guide assemblies are arranged in a stepped manner, so that the wind can enter each of the wind guide plates 24 without being blocked.

[0051] In addition to the two battery boxes 19 on the two sides, a wind distribution assembly 50 is installed on each of the battery boxes 19, the wind distribution assembly 50 comprises a winding shaft 27, the winding shaft 27 is rotatably arranged between two positioning plates 30, a winding cylinder 29 is fixed on the winding shaft 27, a wind guide layer 26 is wound on the winding cylinder 29, the other end of the wind guide layer 26 is fixed in a clamping block 28, the clamping block 28 is arranged on one side of the winding shaft 27, the wind guide layer 26 passes through two guide rollers 25 and is supported by the guide rollers 25;

[0052] It should be noted that the air distribution assembly 50 on the battery box 19 on the base 11 has two guide rollers 25 fixed to the battery box 19 on the base 11, and its positioning plate 30 and clamping block 28 are both fixed to the outer box 12.

[0053] It should be noted that the air distribution assembly 50 on the battery box 19 on the outer casing 12 has two guide rollers 25 that are fixed to the base 11, and its positioning plate 30 and clamping block 28 are fixed to the battery box 19 on the outer casing 12.

[0054] Specifically, one end of the winding shaft 27 passes through the positioning plate 30 and is inserted into the torsion spring box 31. The torsion spring box 31 is fixed to the positioning plate 30. The winding shaft 27 is rotatably installed in the torsion spring box 31. A torsion spring 35 is installed between the winding shaft 27 and the torsion spring box 31. When the winding shaft 27 rotates, the torsion spring 35 between the winding shaft 27 and the torsion spring box 31 will deform.

[0055] It should be noted that one end of the air guide layer 26 is inserted into the clamping block 28. The clamping block 28 has holes and several bolts 41 are inserted. The bolts 41 pass through the clamping block 28 and are fitted with nuts 33. When fixing one end of the air guide layer 26, holes are manually drilled in the air guide layer 26, and the bolts 41 are passed through the holes in the air guide layer 26 and the holes in the clamping block 28. The nuts 33 are then tightened to fix the air guide layer 26.

[0056] In particular, the distance between the guide rollers 25 is greater than the distance between the winding shaft 27 and the clamping block 28, so that the air guide layer 26 is arranged in a triangle.

[0057] After the outer casing 12 rises relative to the base 11, the battery box 19 will pull the air guide layer 26 out from the winding drum 29, so that the air guide layer 26 fills the gap between the battery boxes 19 in a double layer. Due to the triangular arrangement of the air guide layer 26, the air guide layer 26 will guide the air blown in from the through groove 22, so that the air can better act on the battery box 19 and quickly reduce the temperature of the battery box 19.

[0058] In addition, regarding the material selection of the air guide layer 26, using a polymer fireproof film / polymer fireproof cloth is the best choice. In addition to the dense material being able to effectively guide air, it can also play a role in heat insulation and fire prevention.

[0059] It should be noted that the base 11 is provided with multiple sets of exhaust holes 40 to facilitate heat dissipation.

[0060] How to use:

[0061] When it is autumn or winter, the outside temperature is very low, and the inside temperature of the outer casing 12 is not high, so the battery box 19 stores energy normally.

[0062] When it is hot in summer or when the battery box 19 experiences a short circuit and overheating, the temperature sensor 36 detects that the temperature inside the outer casing 12 exceeds a set value. Based on this situation, the control box 37 will automatically control the motor 16 to start. The motor 16 drives the threaded shaft 18 to rotate. Through the threaded connection between the threaded shaft 18 and the threaded block 17, the threaded block 17 is driven to rise. The threaded block 17 drives the outer casing 12 to rise relative to the base 11 to a designated position, and the motor 16 automatically shuts off (by controlling the running time of the motor 16).

[0063] The outer casing 12 rises, causing each of the battery boxes 19 on it to rise, thereby increasing the distance between each of the battery boxes 19 and optimizing heat dissipation.

[0064] On the other hand, after the outer casing 12 is raised, the sealing plate 23 no longer blocks the perforated ventilation plate 13. If there is natural wind outside, it will blow into the air guide chamber 38 through the perforated ventilation plate 13. Guided by the air guide plate 24, the natural wind blows into the outer casing 12 from the through groove 22 to enhance the heat dissipation of all battery boxes 19. The wind is discharged from the exhaust hole 40.

[0065] After the outer casing 12 rises, the battery box 19 will pull the air guide layer 26 out from the winding drum 29, so that the air guide layer 26 fills the gap between the battery boxes 19 in a double layer. Due to the triangular arrangement of the air guide layer 26, the air guide layer 26 will guide the air blown in from the through slot 22, so that the air can better act on the battery box 19 and quickly reduce the temperature of the battery box 19.

[0066] In addition, the air guide layer 26 is made of fireproof material, which can also play a role in heat insulation and fire prevention. In the event that a fire breaks out in one of the battery boxes 19, it will not easily spread.

[0067] When the temperature sensor 36 detects that the temperature inside the outer casing 12 has returned to normal, the control box 37 will start the motor 16 to drive the outer casing 12 to reset. During the reset process of the outer casing 12, the torsion spring 35 resets, so that the winding drum 29 automatically winds up the air guide layer 26.

[0068] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand and implement the present invention. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
