[0006] Two technical solutions

[0007] In order to achieve the above object, the application is implemented by the following technical scheme: a noise reduction sealing rubber strip structure for automobile glass, comprising a door, a window glass, a frame, an assembly rail and a stabilizing device, the frame is fixed on the door, the window glass is installed on the frame, the assembly rail is fixed on one end of the frame, the stabilizing device is arranged on the surface of the assembly rail, the stabilizing device comprises a groove, the groove is arranged on the assembly rail, the upper surface of the assembly rail is provided with a supporting framework and a noise reduction layer, the supporting framework is sleeved on the outer surface of the noise reduction layer, one side of the supporting framework is fixedly connected with an insertion block, the insertion block is inserted into the groove, a cavity is arranged in the inner wall of the supporting framework, and a contraction rubber is fixedly connected to the inner wall of the cavity. By arranging the stabilizing device, the sealing strip can be conveniently disassembled and replaced, and when operating, the insertion block can be separated from the groove by pulling the supporting framework, the elastic force of the elastic pad facilitates the disengagement of the assembly rail, and the reset function of the contraction rubber and the fixing mode of the spring extrusion protrusion ensure the stable installation of the replaced sealing strip, which reduces the difficulty of disassembly and replacement and the damage risk to the surrounding components, maintains the original structural stability and noise reduction sealing performance of the sealing strip, reduces the maintenance time and cost, and improves the maintenance convenience.

[0008] Preferably, the lower surface of the insertion block is fixedly connected with an elastic pad, and the elastic pad is matched with the groove. By arranging the insertion block, when the supporting framework is pulled by force, the insertion block can move synchronously with the supporting framework and separate from the groove, so that the sealing strip can be disengaged from the assembly rail to complete the disassembly. When installing and replacing, the movement of the protrusion is triggered in the process of inserting the insertion block into the groove.

[0032] The two ends of the protruding block are provided with round corners.

[0033] The two protruding blocks are symmetrically arranged, and the protruding block is arranged in a "T" shape.

[0034] One end of the protruding block 58 is fixedly connected with a spring 59, and the end of the spring 59 away from the protruding block 58 is fixedly connected with the assembly rail 4. By arranging the spring 59, after the plug block 55 is inserted into the groove 57 and the elastic pad 56 passes through the protruding block 58, the spring 59 releases the elastic force to press the protruding block 58, so that the protruding block 58 is tightly abutted against the plug block 55, a reliable locking structure is formed, the plug block 55 is prevented from being accidentally detached from the groove 57 under the working conditions such as vehicle vibration, and the stability of the sealing strip after installation is ensured.

[0035] The surface of the support framework 51 is provided with a dust removal device 6. The dust removal device 6 comprises a sponge strip 61 fixedly connected with the support framework 51. One end of the support framework 51 near the sponge strip 61 is fixedly connected with a receiving plate 62. One end of the support framework 51 near the receiving plate 62 is provided with a through hole 63 penetrating through the support framework 51, the noise reduction layer 52 and communicating with the cavity 53. By arranging the dust removal device 6, dust on the surface of the glass can be scraped off by the sponge strip 61 during the sliding process of the glass. The dust enters the cavity 53 through the receiving plate 62 and the through hole 63 and is discharged through the outlet 64.

In the waterproof device 7, the rainwater penetrating into the sealing place between the sealing strip and the glass enters the through hole 63 through the through hole 71 and flows out through the outlet 64, and at the same time, the dust accumulated in the cavity 53 is also taken out, preventing the rainwater from penetrating into the vehicle. In cooperation with the filter frame 72, impurities can be prevented from entering to affect the drainage and dust removal functions, ensuring the stability of the sealing, dust removal and waterproof performance of the sealing strip.

[0037] The dust scraped off the surface of the glass falls on the receiving plate 62, then enters the cavity 53 through the perforation 63 and is discharged from the outlet 64, thereby reducing the situation that the dust blocks the glass slide groove 510, avoiding the influence of dust accumulation on the glass sliding and sealing effect, and ensuring the long-term stability of the sealing performance of the sealing strip.

[0038] The upper surface of the support framework 51 is provided with a waterproof device 7, which includes through holes 71 formed on the surface of the support framework 51, the through holes 71 penetrating the support framework 51 and the noise reduction layer 52 and communicating with the perforation 63, the through holes 71 are multiple and arranged in linear array along the support framework 51, and the inner wall of the through hole 71 is fixedly connected with a filter frame 72.

[0039] The working principle of the present application is as follows: when the sealing strip needs to be disassembled, the support framework 51 is pulled upward, the support framework 51 is driven to disengage the plug 55 from the groove 57, and the plug 55 is bent and disengaged from the assembly rail 4 under the pulling force of the elastic pad 56, so that the sealing strip can be removed.

[0040] The dust scraped off the surface of the glass falls on the receiving plate 62, then enters the cavity 53 through the perforation 63 and is discharged from the outlet 64, thereby reducing the situation that the dust blocks the glass slide groove 510, increasing the sealing effect.

[0041] When it rains, the rain hits the glass and easily penetrates into the sealing part of the sealing strip and the glass. At this time, the rain enters the perforation 63 through the through hole 71, and then the dust outlet 64 flows out, while the filter frame 72 prevents impurities from entering.

[0042] The electrical components described in the text are connected with the main controller and 220V mains, and the main controller can be a computer or other conventional known device that can be controlled.

[0043] Finally, it should be noted that the above only for the preferred embodiments of the present application, and not for the purpose of limiting the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
