[0001] The present invention relates to the technical field of automobile charging port covers, and in particular to a charging port cover installation and sealing structure. Background Art

[0002] The charging port cover structure is an important component of the charging mechanism of pure electric new energy vehicles. It protects the charging socket. The charging port needs to be connected to the charging cable, and the charging cable is connected to the interior of the vehicle body through the holes in the vehicle body. The holes in the vehicle body are prone to poor sealing, which in turn causes various foreign objects to enter the charging socket.

[0003] Therefore, it is necessary to provide a new charging port cover installation and sealing structure to solve the above technical problems. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a charging port cover installation and sealing structure.

[0005] A charging port cover sealing structure provided by the present invention comprises: a charging gun, a charging socket, a mounting bracket, a mounting plate, a mounting hole and a cable, wherein the charging socket is mounted on the surface of the mounting plate, the mounting bracket is slidably mounted on the surface of the charging socket, the charging gun is slidably plugged into the charging socket, the mounting hole is opened on the surface of the mounting plate, the cable is cooperatively mounted on the surface of the mounting hole, and the cable is electrically connected to the charging socket, and further comprises:

[0006] A sealing plastic part is installed on the surface of the mounting bracket, and the sealing plastic part is installed in cooperation with the mounting plate;

[0007] A mounting ring, a mounting ring is rotatably mounted on the surface of the sealing plastic part;

[0008] The arc block is fixedly connected with the surface of the mounting ring symmetrically along the center;

[0009] The cylinder is fixedly connected with the surface of the mounting plate symmetrically along the center;

[0010] The limiting device is slidably installed on the inner wall of the cylinder, and the arc block is installed in coordination with the limiting device.

[0011] Preferably, an adjustment block is symmetrically fixedly connected to the surface of the mounting ring.

[0012] Preferably, the limiting device includes a movable block, a spring, a cylinder, a fixed block, a ball and a spherical groove. The movable block is slidably installed on the inner wall of the cylinder, the surface of the movable block is fixedly connected to the cylinder, the end of the cylinder surface away from the movable block is fixedly connected to the fixed block, the surface of the fixed block is provided with a spherical groove, and the surface of the arc block is symmetrically installed with balls along the center.

[0013] Preferably, the initial state of the spring is a compressed state.

[0014] Preferably, vertical grooves are symmetrically provided on the surface of the cylinder, and both vertical grooves are slidably connected to the movable block.

[0015] Preferably, the surface of the arc block is symmetrically provided with a first oblique groove, and the surface of the fixed block is symmetrically provided with a second oblique groove.

[0016] Preferably, a plurality of connection grooves are provided on the surface of the fixing block, and the plurality of connection grooves are connected to the spherical groove.

[0017] The present invention also provides a charging port cover, comprising any of the above-mentioned charging port cover sealing structures.

[0018] Compared with the related art, the charging port cover installation and sealing structure provided by the present invention has the following beneficial effects:

[0019] The mounting plate of the present invention is a sheet metal vehicle body, and the mounting bracket is integrated with the plastic seal. During installation, the mounting bracket and the plastic seal are sleeved on the surface of the charging socket until the plastic seal contacts the surface of the mounting plate, and then the mounting ring is rotated by the adjusting block. During this process, the first inclined groove contacts the second inclined groove and generates relative sliding. The initial state of the spring is a compressed state, which can ensure that there is sufficient force acting on the surface of the movable block. During the relative sliding between the first inclined groove and the second inclined groove, the spring is further compressed, and the ball contacts the connecting groove until the two spherical grooves are tightly matched with the two balls. The elastic force of the spring is used to make the fixed block and the arc block tightly contact, so that the plastic seal can be in close contact with the surface of the mounting plate, which plays a good sealing role and ensures the sealing performance. The cooperation between the spherical groove and the ball can limit the rotation of the mounting ring, and the elastic force of the spring is also used to make the cooperation between the spherical groove and the ball stable.
