[0027] The sealing performance of the vehicle body has a great influence on the service life of the vehicle and the comfort of the passengers in the cabin, which is one of the important evaluation indicators of the overall quality of the vehicle and directly affects the user experience. In the process of manufacturing a vehicle, there are many process holes such as positioning holes, snatch holes, etc. required by welding, coating and assembly processes. In order to reduce the influence of the above process holes on the sealing performance and passenger comfort, a better sealing performance is required for the process hole sealing cover.

[0028] In order to solve the above technical problems, with reference toFigures 1 to 3 As shown, the application provides a plug cover, comprising a cap 10, a brim 20, a center knot 30 and a sealing part 40, the brim 20 is arranged outside the cap 10 in the radial direction of the plug cover, the center knot 30 is arranged on the cap 10 in the axial direction of the plug cover, the sealing part 40 is arranged on the cap 10 or the brim 20, the sealing part 40 is arranged outside the center knot 30 in the radial direction, and the center knot 30 and the sealing part 40 are arranged in the radial direction. Thus, the brim 20 is arranged outside the cap 10 in the radial direction of the plug cover, and the brim 20 can play a limiting role when the plug cover is plugged; the sealing part 40 can be inserted into the hole of the workpiece to play a sealing role, and the center knot 30 can effectively reduce the problem that the sealing part 40 is deformed too much due to too much insertion force, and can support the sealing part 40 during insertion to have better sealing effect.

[0029] In some embodiments, referring to Figures 1 to 3 As shown, the cap 10, the brim 20, the center knot 30 and the sealing part 40 are arranged as an integrated structure. The cap 10, the brim 20, the center knot 30 and the sealing part 40 are integrally formed by injection molding or other processes, which can reduce manufacturing cost.

[0030] In some embodiments, referring to Figures 1 to 3 As shown, the plug cover is a rubber plug cover, and the Shore hardness of the plug cover is between 40 degrees and 50 degrees. Rubber has high elasticity, wear resistance, corrosion resistance, insulation, air tightness and good processing performance, and can adapt to the deviation of the hole through elasticity to improve its application range.

[0031] In some embodiments, referring to Figures 1 to 3 As shown, the width of the brim 20 in the radial direction of the plug cover is greater than the width of the center knot 30 and the sealing part 40, and after sealing, the brim 20 is located on the surface of the workpiece, and the center knot 30 and the sealing part 40 are located in the hole part of the workpiece. Among them, the width of the brim 20, the width of the center knot 30 and the width of the sealing part 40 in the radial direction of the plug cover are arranged according to actual needs.

[0032] In some embodiments, referring to Figures 1 to 3 As shown, the side of the center knot 30 away from the cap 10 has a plurality of buffer holes 31, the buffer holes 31 are arranged around in the axial direction of the plug cover, and the buffer holes 31 are symmetrically arranged along the center axis. The buffer holes 31 are used to provide a compressed space, which can deform after the center knot 30 is extruded when the plug cover is inserted into the hole of the workpiece, so that the sealing part 40 can be smoothly inserted into the hole part, and the plug cover rebounds under the action of its own elasticity after being inserted into the hole part, thereby having good sealing effect. The number of buffer holes 31 can be four, six or eight, etc., which is selected according to actual situation.

[0033] In some embodiments, referring toFigures 1 to 3 As shown, the sealing part 40 comprises a main body part 41 and a clamping jaw 42, the main body part 41 is protrudingly arranged in the axial direction of the brim 20, and the clamping jaw 42 is arranged on the side of the main body part 41 away from the main body part 41. The depth of the main body part 41 is arranged according to the depth of the hole in the axial direction, the depth of the main body part 41 in the axial direction of the hole is greater than the depth of the hole, and the clamping jaw 42 is located on the side of the hole part away from the cap 10 after the sealing part 40 is inserted into the hole part, and the brim 20 and the clamping jaw 42 respectively seal the axial sides of the hole part.

[0034] In some embodiments, referring to Figures 1 to 3 As shown, the clamping jaw 42 has a claw part 421 protruding outward in the radial direction of the plug, the claw part 421 is bent towards the side of the brim 20, and the clamping jaw 42 has a guide surface 422 extending in the direction of the claw part 421. The claw part 421 can limit the position on the side of the hole part away from the cap 10 to prevent the plug from falling off. The guide surface 422 of the clamping jaw 42 can guide the plug when it is inserted, making it easier to insert the plug into the hole part.

[0035] In some embodiments, referring to Figures 1 to 3 As shown, the sealing part 40 has a sealing surface 43 on the side away from the center joint 30, and the sealing surface 43 is located between the clamping jaw 42 and the brim 20. The sealing surface 43 abuts the hole wall of the hole part, and plays a sealing role after the plug is inserted.

[0036] In some embodiments, referring to Figures 1 to 3 As shown, the plug has a first arc surface 50 connecting the sealing surface 43 and the side of the brim 20 facing the sealing part 40. Since the hole part can be formed by processes such as extrusion and drilling, the edge of the hole part can also be chamfered, so that the first arc surface 50 fits the edge of the hole part more tightly, having a better sealing effect.

[0037] In some embodiments, referring to Figures 1 to 3 Figures 1 to 3 As shown, the brim 20 has a second arc surface 21 on the side away from the sealing part 40, and the second arc surface 21 is arranged between the side of the cap 10 away from the center joint 30 and the side of the brim 20 facing the sealing part 40. When the plug is inserted into the hole part, the second arc surface 21 is located on the outside of the hole part, and the second arc surface 21 can make the surface of the workpiece smoother and more beautiful.

[0038] The application also provides a vehicle comprising the above-mentioned plug, the vehicle has various workpieces, and hole parts are formed on the workpieces, some of which can be used to install connecting members, etc., and some of which can be used as process holes. Arranging the above-mentioned plug in the hole part can play a role in waterproofing and dustproofing.
