Among them, the blocking cloth 402 is installed on one side of the telescopic ring 401, and one end of the blocking cloth 402 away from the telescopic ring 401 is installed on the outer side of the power supply tube 1. The middle connecting ring 4 is inserted into the connecting frame 303, and the connecting frame 303 is fixedly connected to the telescopic ring 401.

[0032] When the device is in use, first rotate the rotating cylinder 3, which drives the rotating support frame 301 to move towards the charging head 2, causing the connecting long rod 302 to move synchronously. And under the connection of the connecting frame 303, it drives the connecting short rod 305, the connecting frame 303, and the middle connecting ring 4 to move in the same direction. The middle connecting ring 4, the telescopic ring 401, and the blocking cloth 402 will expand and become larger simultaneously. When the connecting short rod 305 moves to the vertical position, continue to rotate the rotating cylinder 3, and move the middle connecting ring 4, the connecting frame 303, the telescopic ring 401, and the blocking cloth 402 to the other side of the fixed support frame 306, causing the blocking cloth 402 to contract in the opposite direction, covering the charging head 2 inside. And when the charging head 2 is inserted into the charging port, the telescopic ring 401 is hermetically attached to the car surface. At this time, the telescopic ring 401, the charging head 2, and the car surface form a sealed connection, effectively preventing water leakage during charging.

Figure 1 Among them, the expansion and contraction component further includes a limiting ring 307. The limiting ring 307 is installed on the outer side of the power supply tube 1, and the limiting ring 307 is used for limiting the rotating cylinder 3.

[0035] Figure 2 Shown is an exploded view structure schematic of a specific embodiment of the present utility model. Figure 2 Among them, a plurality of support grooves are provided on the outer side of the rotating support frame 301, and a plurality of support grooves are provided on the outer side of the fixed support frame 306, and the support grooves are used for the rotational connection of the connecting long rod 302 and the connecting short rod 305.

At the same time, the length of the connecting long rod 302 is set to be greater than that of the connecting short rod 305 and is located on both sides of the connecting frame 303 to ensure the accuracy when moving and adjusting the direction of the connecting short rod 305.

[0038] Figure 3Shown is a schematic three-dimensional structure diagram of a specific embodiment of the present utility model. Figure 3 In it, a telescopic ring is provided on the outer ring of one side of the telescopic ring 401. The baffle 402 is located inside the telescopic ring, and both the fixed support frame 306 and the connecting short rod 305 are located inside the baffle 402.

[0039] A sealing ring 5 is provided on one side of the baffle 402, and a sealing ring is provided on the side of the sealing ring 5 close to the charging head 2.

[0040] By setting the baffle 402, the telescopic ring 401, and the middle connecting ring 4 to be all telescopic, the stability of the directional movement of the baffle 402 is ensured. And under the simultaneous sealed connection of the telescopic ring and the sealing ring 5, the sealing stability between the charging port and the charging head 2 is further improved.

[0041] Working principle: First, rotate the rotating cylinder 3 to drive the rotating support frame 301 to move towards the charging head 2, so that the connecting long rod 302 moves synchronously. And under the connection of the connecting frame 303, drive the connecting short rod 305, the connecting frame 303, and the middle connecting ring 4 to move in the same direction. The middle connecting ring 4, the telescopic ring 401, and the baffle 402 will expand and become larger at the same time. When the connecting short rod 305 moves to the vertical position, continue to rotate the rotating cylinder 3 to move the middle connecting ring 4, the connecting frame 303, the telescopic ring 401, and the baffle 402 to the other side of the fixed support frame 306, so that the baffle 402 contracts in the opposite direction to cover the charging head 2 inside it. And when the charging head 2 is inserted into the charging port, the telescopic ring 401 is hermetically attached to the vehicle surface. At this time, the telescopic ring 401, the charging head 2, and the vehicle surface form a sealed connection. At the same time, the middle connecting ring 4 is partially sealed with the charging port, effectively preventing water leakage during charging. After the charging is completed, rotate the rotating cylinder 3 in the reverse direction to drive the waterproof component to move back to its original position. At the same time, under the limitation of the limiting ring 307, ensure the stability of the reset of the rotating cylinder 3.

[0042] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it.
