[0054] The specific embodiment of the present scheme is that the temperature control system includes a cover body 1 placed outside a plurality of battery cells, the cover body 1 is connected to a motor 3 through a support plate, the output shaft of the motor 3 extends to a pinion 4, the outer wall of the pinion 4 is meshed with a large gear 6 fixed on a screw 5, one end of the screw 5 passes through the cover body 1 and extends into a rotating groove on the inner wall of the cover body 1, and a slider 8 fixed on a panel 7 is spirally driven on the screw 5, a guide block 9 is fixedly mounted on the panel 7, and a movable hole connected to a bracket on the inner wall of the cover body 1 is provided on the outer wall of the guide block 9. As the motor 3 is started, the spiral transmission of the screw 5 drives the panel 7 and the guide block 9 to move horizontally. First, the pinion 4 of the present patent design drives the large gear 6 to rotate. Such a transmission relationship can reduce the angular velocity of the rotation, so that the screw 5 can rotate stably and uniformly, so that the cleaning plate 12 can be slowly raised and lowered, so that the speed is too large, thereby affecting the heat dissipation and cleaning ability of the device. In addition, the guide block 9 on the panel 7 is arranged, combined with the attached manual Figure 3 It can be seen that the guide block 9 can be freely moved horizontally on the bracket, thereby further ensuring the accuracy of the movement of the panel 7 and preventing the movement position from deviating.

[0055] The specific embodiment of this scheme is that the panel 7 is equipped with a fan 10 adapted thereto, and the first pillars 11 are fixedly installed at both ends of the outer wall of the fan 10, and the first pillar 11 and the second pillar 13 on the cleaning plate 12 are connected by a swing rod 14, and the swing rod 14 is symmetrically arranged relative to the center of the cover body 1, and a T-block 15 is integrally formed and connected at the center of the cleaning plate 14, and the T-block 15 is connected with a T-slot along the height direction of the inner wall of the cover body 1, and a cleaning brush 16 is adhesively fixed to the cleaning plate 12 near the inner wall of the cover body 1. Figure 3 It can be known that the cleaning plate 12 is rotatably connected to the swing rod 14 mainly because during the back and forth movement of the fan 10, on the one hand, it can ensure that the electrical components inside the cover body 1 ensure uniform and effective heat dissipation, and on the other hand, it provides corresponding power for the up and down movement of the cleaning plate 12. At the same time, the swing rod 14 maintains a rotatable connection setting on the first pillar 11 and the second pillar 13, so that when the fan 10 moves horizontally, the cleaning plate 12 can move freely up and down in cooperation with the T-block 15 on the inner wall of the cover body 1. In addition, a T-block 15 is integrally formed and connected at the center of the cleaning plate 14, and the T-block 15 is connected with a T-slot along the height direction of the inner wall of the cover body 1. The T-slot on the inner wall of the cover body 1 provides corresponding activity space for the up and down movement of the cleaning plate 14, and can also prevent the cleaning plate 12 from deviating from the corresponding moving track.

[0056] A specific embodiment of the present scheme is that both ends of the swing rod 14 are respectively connected to the first pillar 11 and the second pillar 13 by a rotational connection, and an annular groove connected to the swing rod 14 is provided on the outer wall of the first pillar 11 and the second pillar 13. As the panel 7 drives the horizontal movement of the fan 10, the fan 10 drives the cleaning plate 12 on the swing rod 14 to move up and down in a cycle. The annular groove on the pillar ensures effective connection with the swing rod 14 while preventing separation between the structural parts, and also ensures the normal rotation of the swing rod 14.
