[0042] The three ventilation slots 92 are evenly spaced within 270 degrees.

[0043] Specifically, the heat generated by the battery pack 8 in the rotating sleeve 5 can be used to preheat the battery pack 8 in the required fixed sleeve 6, which will not delay the heat dissipation and can make the preheating faster and more energy-saving, thereby saving more electricity for external charging.

[0044] In another embodiment provided by the present invention, the retraction mechanism 7 includes a top block 74 fixedly connected to the upper end of the battery pack 8, a warm block 12 is arranged on the bottom side of the battery pack 8 in the carrying box 2, a fixing plate 72 is sleeved on the outer side of the top block 74, the fixing plate 72 is fixedly connected to the inner wall of the rotating sleeve column 5, arc grooves 73 are opened on two opposite sides of the lower surface of the fixing plate 72, the arc groove 73 extends from the side away from the battery pack 8 to the side close to the battery pack 8, a semicircular ring 71 is slidably arranged in the arc groove 73, a spring 2 78 is fixedly connected between the top side wall of the semicircular ring 71 and the fixing plate 72, the semicircular ring 71 is initially located on the side away from the battery pack 8, a fixing column 75 is fixedly connected to the bottom end of the semicircular ring 71, a trapezoidal plug plate 76 is movably inserted up and down at the bottom end of the inner cavity of the carrying box 2, and a spring 1 77 is fixedly connected between the bottom end of the trapezoidal plug plate 76 and the carrying box 2.

[0045] A plurality of trapezoidal insert plates 76 are arranged in a ring shape at equal intervals.

[0046] The two semicircular rings 71 can be combined to form a cylinder.

[0047] Specifically, through the control of the same motor 11, forward and reverse rotation can achieve different effects, the structure is compact, and the production cost is reduced. Forward rotation of the motor 11 can make preheating more efficient, and the semicircular ring 71 is away from the battery pack 8, which will make the heat dissipation faster. When reversing, the semicircular ring 71 can be brought close to the battery pack 8, so that there is less gas around the battery pack 8, thereby further shortening the next preheating time.

[0048] In another embodiment provided by the present invention, the auxiliary mechanism 13 includes a sliding plate 131 slidably disposed in the semicircular ring 71, and a spring 5 134 is fixedly connected between one end of the sliding plate 131 and the semicircular ring 71, and a blocking portion 132 and a blocking portion 2 133 are provided on the sliding plate 131.

[0049] The sum of the areas of the second blocking portion 133 on the two semicircular rings 71 is equal to the area of ​​one blocking portion 132 , and the area of ​​the first blocking portion 132 is larger than the ventilation groove 92 .

[0050] Specifically, through the cooperation between the sliding plate 131 and the semicircular ring 71, a double-layer seal is formed, which further increases the preheating speed and improves the heat preservation effect.

[0051] Working principle: During use, if the outside temperature is low and the battery pack 8 needs to be preheated, the control unit 3 will first start the warm block 12 to preheat the battery pack 8 in the rotating sleeve column 5. After reaching the appropriate temperature, the battery pack 8 in the rotating sleeve column 5 will first be powered to the outside. After the battery pack 8 in the rotating sleeve column 5 has worked for a period of time, it will generate heat. At this time, the heating of the warm block 12 is stopped, and the cooling fan 10 is started to dissipate the heat of the battery pack 8 in the inner cavity of the rotating sleeve column 5. Next, if it is necessary to use the battery pack 8 in one of the fixed sleeve columns 6, the rotating sleeve column 5 can be rotated by the motor 11 to align the ventilation groove 92 in the middle with the close-fitting sleeve block 91 on the fixed sleeve column 6. At this time, the close-fitting sleeve block 91 on the other fixed sleeve column 6 is not connected to the inner cavity of the rotating sleeve column 5. When the ventilation groove 92 is aligned with the close-fitting sleeve block 91, the abutment plate 93 The airflow from the cooling fan 10 to the rotating sleeve 5 is not too strong, so the airflow from the cooling fan 10 to the rotating sleeve 5 is too strong. The cooling fan 10 is used to cool the rotating sleeve 5 and the airflow from the cooling fan 10 to the rotating sleeve 5 is not too strong. The cooling fan 10 is used to cool the rotating sleeve 5 and the airflow from the cooling fan 10 to the rotating sleeve 5 is not too strong. The cooling fan 10 is used to cool the rotating sleeve 5 and the airflow from the cooling fan 10 to the rotating sleeve 5 is not too strong. The cooling fan 10 is used to cool the rotating sleeve 5 and the airflow from the cooling fan 10 to the rotating sleeve 5 is not too strong. The cooling fan 10 is used to cool the rotating sleeve 5 and the airflow from the cooling fan 10 to the rotating sleeve 5 is not too strong. The airflow from the cooling fan 10 is used to cool the rotating sleeve 5 and the airflow from the cooling fan 10 to the rotating sleeve 5 is not too strong. The airflow from the cooling fan 10 is used to cool the rotating sleeve 5 and the airflow from the cooling fan 10 to the rotating sleeve 5 is not too strong. The airflow from the cooling fan 10 is used to cool the rotating sleeve 5 and the airflow from the rotating sleeve 5 is not too strong. The airflow from the cooling fan 10 is used to cool the rotating sleeve 5 and the airflow from the rotating sleeve 5 is not too strong.

[0052] When in use, looking from top to bottom, the rotating sleeve column 5 rotates clockwise, and the fixed column 75 squeezes the inclined surface of the top of the trapezoidal plug plate 76, so the trapezoidal plug plate 76 moves downward, and the trapezoidal plug plate 76 does not affect the rotation of the fixed column 75. When it is not needed, the rotating sleeve column 5 is reversed, and the trapezoidal plug plate 76 hinders the rotation of the fixed column 75, and then the semicircular ring 71 moves relative to the rotating sleeve column 5. The semicircular ring 71 is guided by the arc groove 73 to move from the side away from the battery pack 8 to the side close to the battery pack 8. At this time, the semicircular rings 71 on both sides will be closed, and the inner walls of the upper and lower ends of the semicircular rings 71 will conflict with the outer walls of the top block 74 and the warm block 12, so that a closed cavity is formed in the semicircular rings 71. Through the control of the same motor 11, forward and reverse rotations can achieve different effects, with a compact structure and reduced production costs. Forward rotation of the motor 11 can make preheating more efficient, and the semicircular rings 71 are away from the battery pack 8, which will make the heat dissipation faster. When reversing, the semicircular rings 71 can be brought close to the battery pack 8, so that there is less gas around the battery pack 8, thereby further shortening the next preheating time;

[0053] When the two semicircular rings 71 are closed, the blocking portion 132 will no longer conflict with the inner wall of the rotating sleeve column 5. Under the action of the spring five 134, the sliding plate 131 is squeezed toward the outer wall of the rotating sleeve column 5, so that the blocking portion 132 and the blocking portion 2 133 conflict with the inner wall of the rotating sleeve column 5, and the ventilation groove 1 92 is blocked. Through the cooperation of the sliding plate 131 and the semicircular ring 71, a double-layer seal is formed, which further improves the preheating speed and the insulation effect.
