Description

Technical Field

[0001] This utility model relates to a sealing technology, particularly a sealing gasket for automotive rearview mirrors. Background Technology

[0002] Existing automotive rearview mirrors, such as those for engineering vehicles, are generally simple in structure and durable due to their usage environment. For example, the structure disclosed in patent CN201821371948.8 includes a rearview mirror housing, an annular sealing strip, and a rearview mirror lens. The annular sealing strip is a groove-shaped sealing strip with an inlay groove, fixed inside the rearview mirror housing. The rearview mirror lens is embedded in the inlay groove of the annular sealing strip. Figure 3 As shown, the inlay groove of the annular sealing strip is U-shaped. The rearview mirror is inlaid in the inlay groove of the annular sealing strip. The outer wall of the inlay groove is only attached to the rearview mirror and cannot press against the rearview mirror with a certain pressure. Rainwater can easily seep into the space between the rearview mirror and the side wall of the inlay groove. The salt stains after the water in the rainwater evaporates will remain on the rearview mirror. Over time, the accumulated salt stains will spread to the periphery of the mirror, seriously affecting the function of the rearview mirror. Summary of the Invention

[0003] The purpose of this invention is to provide a sealing gasket for car rearview mirrors that can overcome one or more of the above-mentioned disadvantages, while ensuring simple structure, low cost, and durability, and preventing rainwater from seeping between the rearview mirror lens and the side wall of the mounting plate, thereby preventing salt stains.

[0004] The sealing gasket for the car rearview mirror of this utility model is implemented as follows: it includes an annular sealing strip body and a U-shaped groove disposed inside the annular sealing strip body. Its special feature is that the outward right side wall of the U-shaped groove is higher than the inward left side wall, and the part of the right side wall of the U-shaped groove that is higher than the left side wall bends towards the left side wall.

[0005] During use, the rearview mirror lens is embedded in the mounting groove of the annular sealing strip. Because the part of the outward right side wall of the U-shaped groove that is higher than the inward left side wall bends to the left side wall, the outward right edge of the rearview mirror lens embedded in the U-shaped groove will push the part of the outward right side wall of the U-shaped groove that is higher than the left side wall outward. Under the action of elasticity, the part of the outward right side wall of the U-shaped groove that is higher than the left side wall will stick tightly to the side edge of the rearview mirror lens, so rainwater cannot seep into the U-shaped groove, thus avoiding the accumulation of rainwater in the U-shaped groove and the formation of salt stains.

[0006] Preferably, the right side of the portion of the outward right side wall of the U-shaped groove that is higher than the inward left side wall is a slope. This slope allows rainwater to exit the rearview mirror along the slope without accumulating between the edge of the rearview mirror and the edge of the portion of the outward right side wall of the U-shaped groove that is higher than the inward left side wall, thus preventing the accumulation of rainwater and the formation of salt deposits.

[0007] Compared with existing technologies, this utility model has the advantages of ensuring simple structure, low cost, and durability, while preventing rainwater from seeping between the rearview mirror and the side wall of the mounting plate, thereby preventing salt stains.

Detailed Implementation

[0012] The sealing gasket for automobile rearview mirrors of this utility model will now be described in further detail with reference to the accompanying drawings and embodiments:

[0013] like Figure 1 , 2 As shown, the sealing gasket for the car rearview mirror of this utility model is implemented as follows: it includes an annular sealing strip body 1, a U-shaped groove 2 disposed on the inner side of the annular sealing strip body 1, and an installation recess 3 for fixing to the rearview mirror housing is provided on the outer side of the annular sealing strip body 1. The special feature is that the outward right side wall 201 of the U-shaped groove 2 is higher than the inward left side wall 202, and the portion 203 of the outward right side wall of the U-shaped groove 202 that is higher than the inward left side wall bends towards the left side wall 202.

[0014] Preferably, the outer surface 204 of the portion 203 of the outward right side wall of the U-shaped groove 2 that is higher than the inward left side wall is an inclined surface.

[0015] Preferably, an outward protrusion 4 is provided on the outer edge of the outer side of the annular sealing strip body 1. The right side of the outward protrusion 4 is a slope, and the outer side of the outward right side wall 201 of the U-shaped groove 2 is a slope. The slope of the right side of the outward protrusion 4, the slope of the outer side of the outward right side wall 201 of the U-shaped groove 2, and the slope of the outer side 204 of the portion 203 of the outward right side wall of the U-shaped groove 2 that is higher than the inward left side wall are integrated into one piece. The outward protrusion 4 can effectively cover the right edge of the rearview mirror housing and prevent rainwater from seeping into the gap between the right edge of the rearview mirror housing and the annular sealing strip body 1.

[0016] In use, the rearview mirror is embedded in the U-shaped groove 2 inside the annular sealing strip body 1. As the right side wall of the U-shaped groove 2, which is higher than the left side wall, bends towards the left side wall 202, the outer edge of the rearview mirror embedded in the U-shaped groove 2 will push the right side wall of the U-shaped groove 2, which is higher than the left side wall, outward. Under the action of elasticity, the right side wall of the U-shaped groove 2, which is higher than the left side wall, will stick tightly to the outer edge of the rearview mirror. Rainwater cannot seep into the U-shaped groove 2. At the same time, rainwater can leave the rearview mirror along the slope and will not stagnate between the edge of the rearview mirror and the edge of the right side wall of the U-shaped groove 2, which is higher than the left side wall, thus avoiding the accumulation of rainwater in the U-shaped groove 2 and the formation of salt stains.
