[0039] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] like Figures 1 to 3As shown, an embodiment of the present invention provides a sealing assembly 1, which is used in a vehicle and can seal between a vehicle window glass 3 and a window frame or a door frame to isolate rain, dust, noise and keep warm. The sealing assembly 1 includes a first sealing bubble tube 11, which is a cavity structure, and the first sealing bubble tube 11 is suitable for connecting with an inflating device 2 of a vehicle. The inflating device 2 can inflate the cavity structure inside the first sealing bubble tube 11, so that the first sealing bubble tube 11 can switch between an inflated state and a non-inflated state.

[0041] The side of the first sealing bubble tube 11 facing the vehicle window glass 3 cooperates with the large surface of the vehicle window glass 3 to form a sealing surface, which can isolate the passenger compartment from the external environment of the vehicle and provide excellent air tightness, water tightness and sound insulation for the vehicle. Through the dynamic change process of inflation, the shape of the first sealing bubble tube 11 can be changed and the sealing surface can be affected. When the first sealing bubble tube 11 is in an inflated state, the contact pressure between the sealing surface of the first sealing bubble tube 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.

[0042] At the same time, in this embodiment, the sealing performance is improved by increasing the sealing surface pressure, and there is a smaller sealing reaction force when cooperating with the vehicle window, which can reduce the wear of the sealing component 1, effectively reduce the resistance of the vehicle window glass 3 during movement, and reduce the abnormal noise caused by friction when raising and lowering the vehicle window glass 3.

[0043] In one embodiment, the material of the first sealing bubble tube 11 is a sponge rubber structure, which can significantly reduce the lifting reaction force when cooperating with the glass, and effectively improve the lifting performance of the vehicle window glass 3.

[0044] In one embodiment, if Figure 2 , Figure 3 As shown, the inner wall of the first sealed bubble tube 11 is provided with at least one protrusion 111 , which can effectively prevent the first sealed bubble tube 11 from sticking after deformation, thereby improving the durability of the first sealed bubble tube 11 .

[0045] In one embodiment, a plurality of protrusions 111 are provided, and the plurality of protrusions 111 are arranged at intervals along the inner wall of the first sealed bubble tube 11, wherein the cavity inside the first sealed bubble tube 11 is a triangular structure, and a protrusion 111 is provided on at least one side of the triangular structure.

[0046] Preferably, a plurality of protrusions 111 are arranged at intervals on the same side of the triangular structure to form a sawtooth shape.

[0047] In one embodiment, if Figure 2As shown, an inflatable plug core 112 is provided in the first sealed bubble tube 11, and the inflatable plug core 112 is suitable for being connected to the inflatable device 2. The inflatable plug core 112 can be inflated through the inflatable device 2, so that the inflatable plug core 112 can be switched between an inflated state and a non-inflated state, thereby switching the first sealed bubble tube 11 between an inflated state and a non-inflated state.

[0048] The inflatable plug core 112 can change its shape by being inflated. Before being inflated, the inflatable plug core 112 is a 6 mm oval tube. After being inflated, the inflatable plug core 112 is a 10 mm round tube. After being inflated, the inflatable plug core 112 expands and becomes larger inside the first sealed bubble tube 11, which can increase the contact pressure between the first sealed bubble tube 11 and the vehicle window glass 3.

The second sealed bubble tube 12 can be inflated by the inflation device 2, so that the second sealed bubble tube 12 can be switched between an inflated state and a non-inflated state. The shape of the second sealed bubble tube 12 can be changed through the dynamic change process of inflation. When the first sealed bubble tube 11 is in the inflated state, the contact pressure between the sealing surface of the second sealed bubble tube 12 and the vehicle window glass 3 can be increased, thereby improving the sealing ability of the sealing assembly 1.

[0053] In one embodiment, if Figure 2 , Figure 3 As shown, the sealing assembly 1 also includes a sealing portion 13 and a mounting portion 14 connected to the vehicle.
