DETAILED DESCRIPTION
[0037] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0038] As shown in FIGS. 1-3, the present application provides a sealing assembly 1 for a vehicle. The sealing assembly 1 can seal between the vehicle window glass 3 and the window frame or door frame, and can play a role of isolating rain, dust, noise and heat preservation. The sealing assembly 1 comprises a first sealing bulb 11, which is a hollow structure and is adapted to be connected with an inflator 2 of the vehicle. The first sealing bulb 11 can be inflated by the inflator 2 to switch between an inflated state and a non-inflated state.
[0039] The side of the first sealing bulb 11 facing the vehicle window glass 3 is in contact with the large surface of the vehicle window glass 3 to form a sealing surface, which can isolate the passenger compartment from the outside environment and provide excellent air tightness, water tightness and sound insulation for the vehicle. Through the dynamic change process of inflation, the morphology of the first sealing bulb 11 can be changed and the sealing surface can be affected. When the first sealing bulb 11 is in the inflated state, the contact pressure between the sealing surface of the first sealing bulb 11 and the vehicle window glass 3 can be increased, thereby improving the sealing ability of the sealing assembly 1 and improving the overall quality of the vehicle.
[0040] Meanwhile, in the present embodiment, the sealing performance is improved by increasing the sealing surface pressure, and when cooperating with the vehicle window, the sealing assembly 1 has a small sealing reaction force, which can reduce the wear of the sealing assembly 1, effectively reduce the resistance when the vehicle window glass 3 moves, and reduce the abnormal noise generated by friction when the vehicle window glass 3 is lifted.
[0041] In some embodiments, the material of the first sealing bulb 11 is a sponge rubber structure. The first sealing bulb 11 with the sponge rubber structure can significantly reduce the lifting resistance when cooperating with the glass, and effectively improve the lifting performance of the vehicle window glass 3.
[0042] In some embodiments, as shown in FIGS. 2 and 3, the inner wall of the first sealing bulb 11 is provided with at least one protrusion 111. By providing the protrusion 111 on the inner wall of the first sealing bulb 11, the adhesion and other conditions after deformation of the first sealing bulb 11 can be effectively prevented, and the durability of the first sealing bulb 11 can be improved.
[0043] In some embodiments, a plurality of protrusions 111 are provided, and the plurality of protrusions 111 are arranged at intervals along the inner wall of the first sealing bulb 11. The cavity inside the first sealing bulb 11 is a triangular structure, and at least one side of the triangular structure is provided with the protrusion 111.
[0044] In some embodiments, the plurality of protrusions 111 are arranged at intervals on the same side of the triangular structure to form a sawtooth shape.
[0045] In some embodiments, as shown in FIG. 2, the first sealing bubble tube 11 is provided with an inflation plug 112, which is adapted to be connected with the inflation device 2. The inflation plug 112 can be inflated by the inflation device 2, so as to switch the inflation plug 112 between the inflated state and the non-inflated state, and further switch the first sealing bubble tube 11 between the inflated state and the non-inflated state.
[0046] The inflation plug 112 can change its shape by inflation. Before inflation, the inflation plug 112 is an oval tube with a diameter of 6 mm. After inflation, the inflation plug 112 is a circular tube with a diameter of 10 mm. After inflation, the inflation plug 112 expands in the first sealing bubble tube 11, which can increase the contact pressure between the first sealing bubble tube 11 and the vehicle window glass 3.
[0047] In some embodiments, as shown in FIG. 2 and FIG. 3, the sealing assembly 1 further comprises a second sealing bubble tube 12, which is oppositely arranged with the first sealing bubble tube 11. A gap is formed between the first sealing bubble tube 11 and the second sealing bubble tube 12 for the insertion of an external sealing member, so as to form a seal. The external sealing member is the vehicle window glass 3. The first sealing bubble tube 11 and the second sealing bubble tube 12 are arranged on opposite sides of the vehicle window glass, which can form a sealing clamping on the vehicle window glass. The side of the first sealing bubble tube 11 facing the vehicle window glass 3 is in contact with the large surface of the vehicle window glass 3 to form a sealing surface. The side of the second sealing bubble tube 12 facing the vehicle window glass 3 is in contact with the large surface of the vehicle window glass 3 to form another sealing surface. Two sealing surfaces are formed to further improve the sealing performance and sound insulation performance of the vehicle.
[0048] In some embodiments, the first sealing bubble tube 11 and the second sealing bubble tube 12 are integrally formed by an extrusion process. The materials of the first sealing bubble tube 11 and the second sealing bubble tube 12 are EPDM dense rubber and EPDM sponge rubber components.
[0049] In some embodiments, the material of the second sealing bubble tube 12 is a sponge rubber structure. The second sealing bubble tube 12 with the sponge rubber structure can significantly reduce the uplift reaction force when cooperating with the glass, and effectively improve the lifting performance of the vehicle window glass 3.
[0050] In some embodiments, as shown in FIG. 2 and FIG. 3, the second sealing bubble tube 12 is a hollow structure, and the second sealing bubble tube 12 is adapted to be connected with the inflation device 2. The second sealing bubble tube 12 can be inflated by the inflation device 2, so as to switch the second sealing bubble tube 12 between the inflated state and the non-inflated state. The dynamic change process of the inflation of the second sealing bubble tube 12 can change the shape of the second sealing bubble tube 12. When the first sealing bubble tube 11 is in the inflated state, the contact pressure between the sealing surface of the second sealing bubble tube 12 and the vehicle window glass 3 can be increased, so as to improve the sealing capacity of the sealing assembly 1.
[0051] In some embodiments, as shown in FIG. 2 and FIG. 3, the sealing assembly 1 further comprises a sealing part 13 and a mounting part 14 connected with the vehicle. The sealing part 13 is connected with the mounting part 14, and the sealing part 13 is mounted on the vehicle body through the mounting part 14. The sealing part 13 is adapted to seal the gap between the mounting part 14 and the vehicle, which can effectively prevent a large amount of rainwater and the like from entering the sealing surface of the sealing assembly 1, and improve the water-tight performance of the vehicle. The sealing part 13 is connected with the mounting part 14 by clamping.
[0052] In some embodiments, the sealing part 13 comprises at least one sealing lip 131 extending away from the mounting part 14, and the sealing lip 131 abuts against the vehicle roof 4 to ensure the sealing effect of the roof 4, thereby avoiding dust, rainwater and the like from entering the driver's cabin through the gap of the roof 4.
[0053] In some embodiments, a plurality of sealing lips 131 are provided and arranged at intervals.
[0054] In some embodiments, as shown in FIG. 2, the sealing part 13, the first sealing bulb 11 and the second sealing bulb 12 are integrally formed by an extrusion process.
