[0028] The utility model will be further described in connection with the drawings and examples:

[0029] Example one: see Figures 1-4As shown, a waterproof automobile power socket, comprising a socket body 1, a power supply interface 2 is arranged at the first end of the socket body 1, a wire 3 connected with the power supply component is arranged at the second end of the socket body 1, a first sealing part 4 for opening and closing the power supply interface 2 is arranged at the first end of the socket body 1, and the first sealing part 4 is rotatably connected with the first end of the socket body 1;

[0030] A reset part 5 is further arranged, which gives the first sealing part 4 a reset force for rotating in the first direction, so that the first sealing part 4 is tightly attached with the end surface of the first end of the socket body 1 at the outer edge of the power supply interface 2, and the power supply interface 2 is sealed.

[0031] In the embodiment, the first end and the second end are arranged at the opposite ends of the socket body 1 respectively, the socket body 1 is arranged on a mounting panel 6, the outer side of the mounting panel can be used as the outer surface of the automobile body, the first end of the socket body 1 is arranged at the outer side of the mounting panel 6, and the second end of the socket body 1 is arranged at the inner end of the mounting panel 6, in this way, the first sealing part 4 is arranged at the outer side of the mounting panel 6, when the first sealing part 4 is turned over and the power supply interface 2 is opened, the power supply interface 2 is directly exposed outside the automobile body, and the user can take power through the power supply interface.

[0032] In the embodiment, the power supply interface can be a cigarette lighter interface, or a USB interface, or a Type-C interface, or a mainstream interface capable of supplying power in the prior art, or a mainstream and commonly used interface in the future, which is not limited here.

[0033] In the embodiment, the reset force of the reset member 5 gives the first sealing part 4 a reset force to rotate towards the first direction in the initial state when the first sealing part 4 is not subjected to external force, so that the outer edge of the inner end surface of the first sealing part 4 abuts against and tightly fits the end surface of the first end of the socket body 1, thereby sealing the power supply interface and preventing external water from entering the power supply interface 2, and further playing a sealing and waterproof role. When external force is applied to the first sealing part 4 and drives the first sealing part 4 to rotate towards the second direction, the first sealing part 4 moves away from the power supply interface 2 and opens the power supply interface 2. The first direction is opposite to the second direction. If the first direction is the clockwise direction, the second direction is the counterclockwise direction. If the first direction is the counterclockwise direction, the second direction is the clockwise direction. For example, in the illustrated direction, the first sealing part is arranged on the first end above the power supply interface, the first direction is the counterclockwise direction, and the second direction is the clockwise direction. When the first sealing part is not subjected to external force, the reset member always gives the first sealing part a reset force to rotate towards the clockwise direction, so that the upper part of the first sealing part rotates clockwise around the socket body and drives the bottom part of the first sealing part to flip upwards, and tightly fits the end surface of the first end at the outer edge of the power supply interface, thereby sealing the power supply interface. When power taking operation is needed, the lower part of the first sealing part is gripped and rotated towards the second direction, i.e. the counterclockwise direction, so that the lower part of the first sealing part flips upwards, and the first sealing part moves away from the end surface of the first end of the socket body and opens the power supply interface, and the user can insert the component (a component cooperating with the power supply interface, such as a plug) needing to take power into the power supply interface.

[0034] Referring to Figure 2 , 4 As shown in the figure, the first sealing part 4 comprises an upper cover 41 and a sealing gasket 42. The upper cover 41 is rotationally connected with the first end of the socket body 1. The sealing gasket 42 is connected with one end of the upper cover 41. The reset force of the reset member 5 drives the upper cover 41 and the sealing gasket 42 to rotate towards the first direction, so that the sealing gasket 42 tightly fits the end surface of the first end of the socket body 1, and seals the power supply interface 2 through the sealing gasket 42.

[0035] In the embodiment, the upper cover is made of a material with certain hardness, such as hard plastic or metal sheet, preferably made of insulating plastic, and the sealing gasket is a silicone sealing gasket. The silicone sealing gasket has good elasticity and sealing performance, is also insulating, and will not cause problems such as conduction or leakage when contacting the power supply interface. Therefore, in the embodiment, the upper cover and the first end of the socket body are rotationally connected to realize the connection between the first sealing part and the socket body, and the sealing gasket is installed on the inner end face of the upper cover. In this way, since the sealing gasket is a flexible sealing material, the upper cover is given a restoring force in the first direction by the restoring member, which drives the flexible sealing gasket to abut against the end face of the first end of the socket body. The restoring force of the restoring member causes the flexible sealing gasket to elastically deform and tightly press against the end face of the first end of the socket body, thereby closing and sealing the power supply interface. At the same time, since the restoring force of the restoring member always exists, it can ensure that the sealing gasket is always tightly attached to the end face of the first end of the socket body, thereby ensuring the sealing and waterproof effect.

[0036] Referring to Figure 4 As shown in the figure, the inner end face of the upper cover 41 is provided with a receiving cavity 43 matched with the sealing gasket 42, the outer end of the sealing gasket 42 is installed in the receiving cavity 43, and the inner end of the sealing gasket 42 is exposed outside the receiving cavity 43.

Preferably, the size of the sealing gasket in the initial state is slightly larger than the size of the receiving cavity, and the outer end of the sealing gasket is installed in the receiving cavity in a tight fit manner. When the sealing gasket is installed, the sealing gasket is quickly installed with the upper cover, and if the sealing gasket is damaged, the sealing gasket can also be quickly disassembled and replaced. In order to ensure that the first sealing part is tightly attached to the end face of the first end of the socket body, the inner end of the sealing gasket is exposed outside the receiving cavity, that is, the thickness of the sealing gasket is greater than the depth of the receiving cavity, so that the sealing gasket abuts against the end face of the first end of the socket body in the closed state of the power supply interface, thereby realizing waterproof sealing. For example, in the direction shown in the figure, when the inner end face of the sealing gasket abuts against the end face of the first end of the socket body, the inner end face of the upper cover and the inner end face of the sealing gasket are arranged towards the power supply interface, and the outer end face of the upper cover and the outer end face of the sealing gasket are respectively arranged on the opposite side of the inner end face of the upper cover and the opposite side of the inner end face of the sealing gasket.

[0040] In the embodiment, the positioning column and the positioning hole are in interference fit, and the accommodating cavity and the outer end of the sealing gasket are also in interference fit. On the basis of the tight fit between the accommodating cavity and the outer end of the sealing gasket, the positioning column and the positioning hole are additionally arranged to increase the connection strength between the sealing gasket and the upper cover, prevent the sealing gasket from being separated from the upper cover, and facilitate the installation, disassembly and replacement of the sealing gasket and the upper cover. In the embodiment, the positioning column is in the form of a plurality of rings arranged in the accommodating cavity in the annular structure. Since the annular part and the accommodating cavity are in interference fit, and the outer diameter of the positioning column is greater than the diameter of the positioning hole, when the sealing gasket and the accommodating cavity are assembled, the positioning column is inserted into the positioning hole, and the sealing gasket is further pressed in the accommodating cavity, so that the connection firmness of the sealing gasket and the upper cover is ensured.

In this way, the tension spring is away from the pin shaft, and a blind hole can be arranged on the end surface of the first end of the socket body, one end of the tension spring is connected with the blind hole, and the other end is connected with the upper cover. The reset force for rotating the upper cover in the first direction is given by the tension spring, so that the sealing gasket is pressed against the end surface of the first end of the socket body, and sealing and waterproof are achieved. Of course, the two ends of the tension spring can also be connected with the outer edge of the first end of the socket body and the outer edge of the first sealing part (the upper cover) respectively, so as to ensure that the tension spring always gives the first sealing part a reset force for rotating in the first direction.
