[0002] Chinese Patent Document No. CN208325045U, published on January 4, 2019, discloses an automotive exterior rearview mirror and a sealing assembly. This invention aims to solve the problem of poor sealing performance in existing exterior rearview mirrors mounted on car door panels. To this end, the exterior rearview mirror of this invention includes a rearview mirror body, a mounting bracket, and a sealing structure. One end of the mounting bracket is connected to the exterior rearview mirror body, and the other end can be connected to the car door. The sealing structure is sealed and fitted onto the mounting bracket and sealed to the exterior rearview mirror body. The sealing structure is configured to seal tightly against the car door panel when the mounting bracket is connected to the car door. The sealing gasket of this structure presses against the car door panel through an annular flange, thereby achieving a waterproof seal between the car door and the rearview mirror. However, the sealing effect is generally poor and cannot completely prevent water from entering the car door.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] See Figures 1-12 The sealing installation structure of the rearview mirror of this car door includes a rearview mirror 2 installed on the car door 1, and a sealing gasket 3 set (pressed) between the car door 1 and the rearview mirror 2. The sealing gasket 3 is sealed to the rearview mirror 2. The sealing gasket 3 is provided with a sealing part that fits tightly with the car door 1, thereby sealing the gap between the car door 1 and the rearview mirror 2.

[0030] The sealing part includes a sealing rib 4 and a sealing edge 5 located at the edge of the sealing gasket 3. The sealing edge 5 is located outside the sealing rib 4. The sealing rib 4 is tightly fitted with the outer side surface 6 of the door 1. The sealing edge 5 is tightly fitted with the outer side surface 6 of the door 1, which can prevent water from entering the interior of the door 1 from the gap between the door 1 and the rearview mirror 2. The sealing edge 5 can achieve a preliminary seal, preventing most of the water from entering the interior of the door 1. The sealing rib 4 can achieve a second seal. Moreover, since the sealing rib 4 is tightly fitted with the outer side surface 6 of the door 1, it can completely prevent water from entering the interior of the door 1.

[0031] The sealing rib 4 is pressed on the outer side 6 of the door 1, and the sealing rib 4 is bent towards the rearview mirror 2, which can increase the contact area between the sealing rib 4 and the outer side 6 of the door 1, thereby improving the sealing effect.

[0032] A sealing groove 7 is formed between the sealing rib 4 and the sealing edge 5 to cooperate with the outer side of the door 1. The outer part of the door 1 is embedded in the sealing groove 7, so that the outer side of the door 1 is tightly fitted with the sealing gasket 3, thereby improving the sealing effect.

[0033] A sealing inner edge 8 is provided on one end edge of the rearview mirror 2. The sealing edge 5 and the sealing inner edge 8 fit together to prevent water from entering the interior of the rearview mirror 2 from the gap between the car door 1 and the rearview mirror 2.

[0034] Sealing gasket 3 is made of TPE material, which is a mixture of thermoplastic resin and elastomer phase. TPE has rubber-like elasticity and softness and can maintain its elastic shape at room temperature. This property allows TPE to adapt to various shapes and curves, while also increasing its comfort and safety in application. Since TPE usually contains components with good wear resistance, such as nitrile rubber (NBR) or acrylonitrile butadiene rubber (NBR), it has good wear resistance. This makes TPE suitable for applications that require long-term use and involve a certain amount of friction or contact, such as automotive seals and industrial parts. Therefore, using TPE material for sealing gasket 3 can improve the sealing effect.

[0035] The rearview mirror 2 is provided with a mounting base 9 at one end. The mounting base 9 is inserted into the inner cavity 10 of the door 1. The rearview mirror 2 is detachably mounted on the door 1 through the mounting base 9.

[0036] A mounting part is provided between the mounting base 9 and the door 1. The rearview mirror 2 is mounted on the door 1 through the mounting part. A through hole 23 is provided on the outside of the door 1. The mounting base 9 is inserted into the inner cavity 10 of the door 1 through the through hole 23. The sealing gasket 3 covers the through hole 23. The sealing gasket 3 can prevent water from flowing from the gap between the door 1 and the rearview mirror 2 into the through hole 23 and then into the interior of the door 1 through the through hole 23.

[0037] The sealing gasket 3 is provided with a fitting part 11, which is fitted onto the mounting base 9 and inserted into the inner cavity 10 of the door 1. The mounting base 9 and the fitting part 11 are triangular in shape.

[0038] A positioning post 12 is provided at one end of the rearview mirror 2, and a positioning hole 13 is provided on the sealing gasket 3. The positioning post 12 passes through the positioning hole 13, thereby positioning the sealing gasket 3 on the rearview mirror 2.

[0039] The rearview mirror 2 includes a mounting part 14 and a mirror body part 15. A mounting base 9 is located at one end of the mounting part 14, and a sealing gasket 3 is located between the mounting part 14 and the door 1. A rotating shaft 16 is provided on the mounting part 14, and a rotating seat 17 is provided on the mirror body part 15. The rotating seat 17 has a rotating hole 18 that rotatably engages with the rotating shaft 16, thereby allowing the mirror body part 15 to be rotatably mounted on the mounting part 14, enabling the mirror body part 15 to be folded and unfolded. The mounting part 14 has several limiting steps 19 arranged in a ring, with limiting grooves 20 formed between adjacent limiting steps 19. The rotating seat 17 has several limiting parts 21 arranged in a ring, and the rotating shaft 16 and... An elastic element 22, which is a spring, is provided between the rotating seats 17. When the mirror body 15 rotates to the corresponding position, the limiting part 21 is engaged in the limiting groove 20 under the elastic force of the elastic element 22, thereby limiting the mirror body 15 after folding and storing or opening. When the mirror body 15 rotates under the action of external force (manual or motor driven), the limiting part 21 moves out of the limiting groove 20 after passing the limiting step 19 and compresses the elastic element 22. The limiting part 21 is provided with a first guide slope 24 on both sides, and the limiting step 19 is provided with a second guide slope 25 on both sides. The limiting part 21 passes over the limiting step 19 through the cooperation of the first guide slope 24 and the second guide slope 25.

[0040] The mounting part 14 includes a mounting bracket 26 and a cover 27. The mounting base 9 is integrally mounted on the mounting bracket 26. The mounting part includes a fixing hole 28 provided on the inside of the door 1 and a fixing post hole 29 provided on the mounting base 9. The screw passes through the fixing hole 28 and is fastened to the fixing post hole 29 so that the mounting part 14 is fixed on the door 1. The cover 27 covers the outside of the mounting bracket 26 and is connected to the mounting bracket 26 by screws.

[0041] The mirror body 15 includes a mirror body 30 and a rotating seat 17, which are connected by screws. The rotating seat 17 is located inside the mirror body 30.

[0042] The inner sealing edge 8 is located on one side of the protective cover 27, the positioning post 12 and the limiting step 19 are located on the mounting bracket 26, and the rotating shaft 16 is fixed on the mounting bracket 26.
