On the one hand, high-power fast charging technology will continue to mature and popularize, and the charging time will be shortened.

[0003] The patent with the publication number CN214492576U relates to a charging pile with heat dissipation and anti-theft functions, which comprises a charging pile body and a base. The base is rectangularly arranged with air outlet holes on the front and rear sides, and a wireless transceiver module is fixed to the inside lower side of the base. The left and right ends of the base are threaded through ground screws. The charging pile body is inserted into the upper end of the base, and the upper end of the charging pile body is provided with air inlet holes on the front and rear sides. The lower side of the charging pile body is linearly arranged with air passing holes, and a fan is fixed to the lower side of the charging pile body.

[0025] The fireproof device 15 comprises a dry powder box 151 fixedly connected to the inner wall of the charging pile body 1, the inner wall of the dry powder box 151 is rotatably connected with a movable door 152, the bottom of the dry powder box 151 is fixedly connected with a sliding groove 153, the inner wall of the sliding groove 153 is slidably connected with an L-shaped baffle 154, the right side of the brush plate 13 is fixedly connected with a connecting plate 155, the right side of the connecting plate 155 is fixedly connected with a triangular plate 156, when a fire or smoke generated by a fire occurs inside the charging pile, the smoke will be detected by the smoke detector 14, thereby prolonging the time of the motor 11 rotating clockwise, so that the brush plate 13 continues to move upward at the position where it would have stopped, thereby causing the brush plate 13 to move the connecting plate 155, the connecting plate 155 moves the triangular plate 156, the triangular plate 156 will contact and press the inclined angle plate 157 during movement, causing the inclined angle plate 157 to move forward, the inclined angle plate 157 moves the L-shaped baffle 154 forward, so that the movable door 152 is released from the limit, thereby allowing the dry powder in the dry powder box 151 to be sprayed to the location of the fire, thereby quickly controlling the fire and preventing the fire from rapidly expanding in a short period of time, thereby gaining valuable time for personnel evacuation and further rescue work, the bottom of the L-shaped baffle 154 is fixedly connected with the inclined angle plate 157, the top of the brush plate 13 is fixedly connected with an A-shaped plate 158, the bottom of the brush plate 13 is fixedly connected with a fixed plate 159, the inner wall of the fixed plate 159 is rotatably connected with a brush roller 1510, the central shaft of the brush roller 1510 is rotatably connected with a transmission wheel 1511, the bottom of the dry powder box 151 contacts the top of the L-shaped baffle 154, the bottom of the movable door 152 contacts the top of the L-shaped baffle 154, the top of the triangular plate 156 contacts the bottom of the inclined angle plate 157, the top of the connecting plate 155 contacts the bottom of the A-shaped plate 158, the left side of the ventilation window 3 contacts the circumferential surface of the transmission wheel 1511, and at the same time the brush plate 13 moves the fixed plate 159, the fixed plate 159 moves the brush roller 1510, the brush roller 1510 moves the transmission wheel 1511, the transmission wheel 1511 moves and contacts the ventilation window 3 during movement and generates friction, causing the transmission wheel 1511 to rotate, the transmission wheel 1511 rotates the brush roller 1510, thereby further improving the ventilation effect of the ventilation window 3 and preventing the ventilation window 3 from being blocked, causing the temperature inside the charging pile to be too high.

[0026] When the charging pile is impacted, the vehicle will impact the buffer plate 5, causing the buffer plate 5 to move backward, and the buffer plate 5 will be buffered by the elastic expansion column 4, thereby being able to reduce the impact force on the charging pile to a certain extent, and further being able to protect the charging pile to a certain extent.
