[0028] Currently, the charging socket 200 has a mounting hole 210. Bolts are installed at the mounting hole 210 to connect the terminal to the charging socket 200. To achieve the sealing between the charging socket 200 and the terminal, a sealing cover 100 needs to be assembled at the mounting hole 210. The sealing cover 100 is mostly an independent part and needs to be installed after the bolts are installed. Before the installation of the sealing cover 100 and after its disassembly, since the sealing cover 100 is an independent part, there is a problem of being easily lost.

[0029] To solve the above problems, please refer to Figures 1 to 9 . The embodiment of the present application provides a sealing cover 100. The sealing cover 100 is pre-installed on the charging socket 200, so that the sealing cover 100 overcomes the problem of being easily lost, and meets the requirement of sealing after installing the bolts, while meeting the sealing strength requirement. The sealing cover 100 includes a fixed connection part 110 and a cover plate 120, where:

[0030] The fixed connection part 110 is connected to the charging socket 200 to realize pre-installing the cover plate 120 on the charging socket 200 and provide stable support. The side of the fixed connection part 110 away from the charging socket 200 has a mounting groove 111. Please refer to Figure 1 , Figure 1 which shows the overall structure of the cover plate provided by the embodiment of the present application from one perspective. The cover plate 120 includes a first body 121 and a rotating shaft 122. The rotating shaft 122 passes through the mounting groove 111, and the first body 121 is connected to the rotating shaft 122. The rotating shaft 122 can make the first body 121 rotate around the rotating shaft 122 to realize the opening of the cover plate 120 (please refer toFigure 4 , Figure 4 illustrates the open state and closed state of the sealing cover provided by the embodiment of the present application) (please refer to Figure 3 , Figure 3 illustrates the sealed state of the sealing cover provided by the embodiment of the present application). The rotating shaft 122 drives the first body 121 to rotate to close the cover plate 120, so that the first body 121 seals the mounting hole 210. In this embodiment, by pre-installing the sealing cover 100 on the charging socket 200, the problem that the sealing cover 100 is easily lost when it is a loose part is solved, and at the same time, the function of sealing the mounting hole 210 is ensured. In addition, the rotating shaft 122 can also drive the first body 121 to rotate to the maximum opening and closing angle, which is convenient for the operator to perform other process operations at the mounting hole 210. That is, this embodiment also meets the requirement that other operations can be performed at the mounting hole 210 before the mounting hole 210 is sealed.

[0031] In some embodiments, the fixed connection part 110 includes a second body 115 and a first limiting flange 112. The mounting groove 111 is opened on the second body 115. The second body 115 is connected to the first limiting flange 112, and the first limiting flange 112 is arranged on the side of the second body 115 away from the mounting groove 111. The cover plate 120 further includes a second limiting flange 123. The second limiting flange 123 is connected to the first body 121, and the second limiting flange 123 is arranged on the side of the first body 121 close to the fixed connection part 110. When the rotating shaft 122 drives the first body 121 to rotate to the maximum opening and closing angle, the second limiting flange 123 is in interference fit with the first limiting flange 112.

[0032] Specifically, the second body 115 can be a cylindrical structure, and the mounting groove 111 is opened in the direction of the second body 115 facing the mounting hole 210. A part of the second body 115 extending outward on the side away from the mounting groove 111 forms the first limiting flange 112, and the cross section of the first limiting flange 112 is triangular. A part of the first body 121 extending outward on the side close to the fixed connection part 110 forms the second limiting flange 123, and the cross section of the second limiting flange 123 is triangular. When the first body 121 rotates with the rotating shaft 122 to the cover plate 120 sealing the mounting hole 210, the second limiting flange 123 rotates and flips to the lower side of the first limiting flange 112 to form an interference fit with the first limiting flange 112. Through the interference fit between the second limiting flange 123 and the first limiting flange 112, when the rotating shaft 122 drives the first body 121 to rotate to the maximum opening and closing angle, the relative position between the cover plate 120 and the fixed connection part 110 is limited, avoiding the cover plate 120 rotating randomly during transportation or when colliding and the structure being damaged when the cover plate 120 is not sealed on the mounting hole 210, thereby prolonging the service life of the sealing cover 100.

[0033] In some embodiments, the interference fit between the second limiting flange 123 and the first limiting flange 112 is 0.5 mm to 0.7 mm. If the interference fit is less than 0.5 mm, the limiting effect between the second limiting flange 123 and the first limiting flange 112 is poor; if the interference fit is greater than 0.7 mm, the limiting interference between the second limiting flange 123 and the first limiting flange 112 is large, the rotational force is large, and burrs and brittle fractures are likely to occur on the plastic part during rotation.

[0034] In some embodiments, the opening and closing angle between the cover plate 120 and the mounting hole 210 is greater than 90°, which can ensure that the operator can perform other operations from the mounting hole 210.

[0035] In some embodiments, please refer to Figure 7 and Figure 8 , Figure 7 shows the cross-sectional structure of the sealing cover provided by the embodiment of the present application when in the closed state, Figure 8 shows the cross-sectional structure details of the sealing cover provided by the embodiment of the present application when in the closed state. The fixed connection part 110 further includes a first support member 113 and a second support member 114. One end of the first support member 113 is connected to the second body 115, and the other end of the first support member 113 is connected to the charging socket 200; one end of the second support member 114 is connected to the second body 115, and the other end of the second support member 114 is connected to the charging socket 200.

[0036] Specifically, the functions of the first support member 113 and the second support member 114 are to provide additional support and stability. The first support member 113 and the second support member 114 support the second body 115, and by connecting with the charging socket 200, provide better support force for the entire fixed connection part 110.

[0037] In some embodiments, the space surrounded by the first support member 113, the second body 115, the second support member 114, and the charging socket 200 is triangular or trapezoidal. The design of the triangular or trapezoidal shape optimizes the structure and space utilization rate of the fixed connection part 110. By gradually increasing the size of the bottom support members (the first support member 113 and the second support member 114) to form a triangular or trapezoidal shape, the available space can be utilized to the greatest extent. The design of the triangular or trapezoidal shape also brings some additional benefits. First, the triangular or trapezoidal shape can increase the connection stability and support force. Second, it can reduce the weight of the entire fixed connection part 110, making it lighter and more compact. In addition, the triangular or trapezoidal shape can also increase the rigidity and strength of the fixed connection part 110, enabling it to withstand greater forces and vibrations, thereby improving the connection stability and reliability.

[0038] In some embodiments, the fixed connection part 110 and the charging socket 200 are of an integral structure; alternatively, the fixed connection part 110 and the charging socket 200 are of a split structure.

[0039] Specifically, when the fixed connection part 110 and the charging socket 200 are of an integral structure, the first limiting flange 112, the first support member 113, the second support member 114, and the second body 115 are integrally formed with the charging socket 200, or the first limiting flange 112, the first support member 113, the second support member 114, and the second body 115 are of an integrally formed structure, denoted as an a-integrally formed structure, and the a-integral structure is welded to the charging socket 200.

[0040] When the fixed connection part 110 and the charging socket 200 are of a split structure, the first limiting flange 112, the first support member 113, the second support member 114, and the second body 115 may be of an integrally formed structure, denoted as a b-integrally formed structure, and a detachable connection (the detachable connection includes but is not limited to snap connection, bolt connection, screw connection, etc.) is adopted between the b-integral structure and the charging socket 200. Alternatively, the first limiting flange 112 and the second body 115 are of an integrally formed structure, denoted as a c-integrally formed structure, and the c-integral structure and the first support member 113 and the second support member 114 are connected by welding or a detachable connection (the detachable connection includes but is not limited to snap connection, bolt connection, screw connection, etc.) to form a first structure, and a detachable connection (the detachable connection includes but is not limited to snap connection, bolt connection, screw connection, etc.) is adopted between the first structure and the charging socket 200.

[0041] In some embodiments, the charging socket 200 includes a third body 240, a first sealing part 220, and a third limiting flange 230. The third body 240 has an installation hole 210. The first sealing part 220 surrounds the installation hole 210 and is connected to the third body 240. The first sealing part 220 has a receiving cavity 221, and the receiving cavity 221 communicates with the installation hole 210. The third limiting flange 230 surrounds the outer periphery of the first sealing part 220 and is connected to the first sealing part 220. The cover plate 120 further includes a limiting plate 124, and the limiting plate 124 is disposed on a side of the first body 121 away from the rotating shaft 122. Wherein, when the rotating shaft 122 drives the first body 121 to rotate to cover and seal the first sealing part 220, the limiting plate 124 is connected to the third limiting flange 230 so that the cover plate 120 covers and seals the receiving cavity 221.

[0042] Specifically, the first sealing portion 220 and the third body 240 are an integrated structure. The first sealing portion 220 is equivalent to raising the sealing opening of the mounting hole 210, so as to better seal the mounting hole 210. The outer periphery of the first sealing portion 220 extends away from the center direction of the mounting hole 210 to form a third limiting flange 230. The limiting plate 124 is recessed into the inner part of the limiting plate 124 at one end portion facing the fixed connection portion 110, and the limiting plate 124 forms a structure with an L-shaped cross section. The limiting plate 124 with an L-shaped cross section can cooperate with the third limiting flange 230 to form a snap connection. The side of the third limiting flange 230 away from the mounting hole 210 is set as an inclined surface, so that before the limiting plate 124 moves to connect with the third limiting flange 230, the limiting plate 124 can better move to the bottom of the third limiting flange 230 along the inclined surface. When the first body 121 rotates with the shaft to cover the accommodating cavity 221, the limiting plate 124 rotates accordingly to engage with the third limiting flange 230. In this embodiment, the limiting plate 124 cooperates with the third limiting flange 230 to achieve a connection between the cover plate 120 and the first sealing portion 220, thereby achieving a certain sealing effect.

[0043] In some embodiments, see Figure 2 and Figure 9 , Figure 2 The overall structure of the cover plate provided by the embodiment of the present application from another perspective is illustrated; Figure 9 The disassembly of the sealing cover provided in the embodiment of the present application is illustrated. After the cover plate 120 of the present embodiment is sealed on the accommodating cavity 221, it can be disassembled from the accommodating cavity 221. The cover plate 120 has a disassembly hole 126, which is arranged on the side of the first body 121 away from the fixed connection part 110, and the disassembly hole 126 passes through the first body 121. When the rotating shaft 122 drives the first body 121 to rotate until the cover is sealed on the accommodating cavity 221, a cavity is formed between the limiting plate 124 and the first sealing part 220, and the disassembly hole 126 is connected to the cavity. Through an external tool, it is inserted from the disassembly hole 126, and the external tool gradually moves downward along the inclined surface of the third limiting flange 230 until the limiting plate 124 is tilted away from the center of the mounting hole 210, and the connection between the limiting plate 124 and the third limiting flange 230 is released, so that the cover plate 120 can be disassembled from the accommodating cavity 221. This embodiment enables the sealing cover 100 to be detachable, thereby having a wider range of applications.

[0044] In some embodiments, the limiting plate 124 has at least one opening groove 1241. The opening groove 1241 is arranged along the thickness direction of the first body 121, and the opening of the opening groove 1241 penetrates through the side of the limiting plate 124 away from the first body 121. The opening groove 1241 can increase the elasticity of the limiting plate 124. When the number of the opening grooves 1241 is two, the two opening grooves 1241 are symmetrically distributed on the limiting plate 124 along the width direction of the limiting plate 124. It is only necessary that the cross-section of the part of the limiting plate 124 between the two opening grooves 1241 is L-shaped. During disassembly, only by prying the part of the limiting plate 124 between the two opening grooves 1241 can the disassembly between the cover plate 120 and the receiving cavity 221 be realized. Since the limiting plate 124 needs to be lifted during disassembly, the elasticity of the limiting plate 124 is increased by providing the opening groove 1241 on the limiting plate 124, so that the connection strength between the limiting plate 124 and the third limiting flange 230 meets the requirements and is more easily lifted.

[0045] In some embodiments, the cover plate 120 further includes a second sealing portion 125 and a sealing member 300. The second sealing portion 125 is connected to the first body 121. When the rotating shaft 122 drives the first body 121 to rotate to cover and seal the receiving cavity 221, the second sealing portion 125 is located inside the receiving cavity 221, and there is a gap between the second sealing portion 125 and the first sealing portion 220. The sealing member 300 is located in the gap. When the rotating shaft 122 drives the first body 121 to rotate to cover and seal the receiving cavity 221, the sealing member 300 is respectively in contact with the first sealing portion 220 and the second sealing portion 125.

[0046] Specifically, the second sealing portion 125 has a cylindrical structure with a hollow interior. The outer diameter of the second sealing portion 125 is smaller than the inner diameter of the first sealing portion 220. The inner diameter of the sealing member 300 is larger than the inner diameter of the second sealing portion 125, and the outer diameter of the sealing member 300 is larger than the inner diameter of the first sealing portion 220. That is, in this application, the first body 121 covers and seals the receiving cavity 221. For better sealing performance, through the cooperation of the second sealing portion 125, the sealing member 300 and the first sealing portion 220, the contact seam between the first body 121 and the first sealing portion 220 is sealed. In this embodiment, through the cooperation of the limiting plate 124 and the third limiting flange 230, the connection between the cover plate 120 and the first sealing portion 220 is realized, achieving a certain sealing effect; combined with the cooperation of the second sealing portion 125, the sealing member 300 and the first sealing portion 220, the cover plate 120 further seals the mounting hole 210.

[0047] In some embodiments, the seal 300 is made of liquid silicone rubber. To meet the sealing strength requirements, at least two reinforcing ribs are provided along the circumference of the outer periphery of the seal 300. Through the arrangement of the reinforcing ribs, the seal 300 can fit more closely on the first sealing portion 220, forming a stronger sealing effect, thereby increasing the sealing strength between the seal 300 and the first sealing portion 220.

[0048] Correspondingly, an embodiment of the present application further provides an automobile, which includes the above-mentioned sealing cover 100. It can be understood that the automobile can have all the technical features and technical effects of the above-mentioned sealing cover 100, which will not be elaborated here.
