Protective pads are installed on the opposite sides of the two arc grooves to protect the harness.

[0029] In this embodiment, a shielding structure extending into the groove 9 is provided inside the sealing plate 3; the shielding structure includes a shielding plate 12 slidably provided in the groove 9, a motor 13 fixedly installed on the upper surface of the sealing plate 2 and extending into the groove 9, a gear 14 fixedly installed on the output shaft of the motor 13, and a rack 15 meshed with the outside of the gear 14 and fixed to one side of the shielding plate 12. A cooling fan 11 adapted to the heat dissipation hole 10 is fixedly installed on the lower surface of the sealing plate 3, and a slide groove 16 is provided inside the groove 9, and the shielding plate 12 is slidably connected to the slide groove 16. The motor 13 is started to drive the gear 14 to rotate, and the gear 14 rotates and meshes with the two racks 15 to drive the two shielding plates 12 to move relative to each other, so that the shielding plate 12 no longer blocks the groove 9, and at this time, the heat dissipation of the junction box 1 is processed through the heat dissipation hole 10 and the cooling fan 11.

[0030] In this embodiment, a temperature sensor 20 is installed on the inner wall of the junction box 1. By installing the temperature sensor 20, the internal temperature of the junction box 1 can be monitored in real time to avoid the internal temperature of the junction box 1 being too high, thereby facilitating better heat dissipation. A battery module is installed inside the junction box 1, and a mounting plate 2 is fixedly installed on the lower surface of the junction box 1. A dustproof net 17 is provided on the upper surface of the sealing plate 3 to shield the groove 9, and a mounting hole 18 for mounting and fixing is provided in the dustproof net 17. The shielding plate 12 shields the groove 9 through the motor 13, the gear 14 and the rack 15, so as to shield the heat dissipation hole 10 and reduce the entry of dust.

[0031] It should be noted that the number of the grooves 9, the shielding plates 12 and the racks 15 are all two, and the two grooves 9, the two shielding plates 12 and the two racks 15 are symmetrically arranged, a slider is installed on one side of the two racks 15 close to the inner bottom wall of the sealing plate 3, and a guide groove adapted to the slider is provided inside the sealing plate 3. The length of the guide groove is adapted to the moving distance of the shielding plates 12 and the length of the racks 15.

[0032] The working principle of the above embodiment is:

[0033] During use, the temperature inside the junction box 1 is monitored by the temperature sensor 20. When the temperature is greater than a preset value, the motor 13 is started to drive the gear 14 to rotate. The gear 14 rotates and engages with the two racks 15 to drive the two baffles 12 to move relative to each other, so that the baffles 12 no longer block the groove 9. At this time, the junction box 1 is cooled by the heat dissipation holes 10 and the heat dissipation fan 11, and the dustproof net 17 can perform dust prevention. When the temperature is lower than the preset value, the baffle 12 blocks the groove 9 through the motor 13, gear 14 and rack 15, thereby blocking the heat dissipation holes 10 and reducing the entry of dust.

The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.
