Description

Technical Field

[0001] The utility model relates to the technical field of automobile exterior rearview mirrors, in particular to a rearview mirror foot sealing structure. Background Art

[0002] A rearview mirror is a tool that allows drivers to directly obtain external information from behind, to the sides, and below the vehicle while sitting in the cab. To facilitate operation, prevent traffic accidents, and ensure personal safety, all countries have mandated the installation of rearview mirrors on vehicles, and all mirrors must be adjustable. Currently, automotive rearview mirrors primarily consist of two components: the lens and the foot. The lens provides the driver with an indirect field of view, while the foot connects the vehicle body to the lens. Due to their novel design, reduced wind resistance, simplified assembly, and increased field of view, integrated exterior mirrors are increasingly being adopted by automakers. These designs combine the lens adjuster and lens folder found in traditional rearview mirrors into a single, higher-performance motor.

[0003] However, the current design of integrated rearview mirrors to avoid dust and wind noise problems in the shield and bowl generally adopts a soft rubber interference fit design. This design is affected by the structure, and some dust particles will be scattered on the unsealed folding surface, causing the rearview mirror to have quality problems such as uneven folding, increased folding resistance, and abnormal folding noise during the folding process. This has caused complaints from vehicle manufacturers and terminal drivers, and has become a bottleneck for improving the company's product quality. Therefore, we provide a new dust and wind noise proof design. Utility Model Content

[0034] Example:

[0035] Reference Figure 1 and Figure 2 The rearview mirror foot sealing structure of this embodiment includes a shield 1, a ball bowl 2 and a sealing sleeve 3 arranged between the shield 1 and the ball bowl 2.

[0036] The sealing sleeve 3 includes a sealing frame 31 and a sealing ring 32 fixed on the sealing frame 31. The sealing frame 31 is provided with a sealing groove 311 for fixing the sealing ring 32, which facilitates the fixing of the sealing ring 32 on the sealing frame 31.

[0037] Combine Figure 3The outer wall of the sealing frame 31 is connected to the inner wall of the shield 1, and the sealing ring 32 extends a flange 321 toward the circumferential side. One side of the flange 321 is tightly against the shield 1, and the other side of the flange 321 is tightly against the guide surface 21 on the bowl 2. This forces the gap between the shield 1 and the bowl 2 to close, thereby reducing dust particles from being scattered on the unsealed folding surface, helping to reduce problems such as uneven folding between the shield 1 and the bowl 2, increased folding resistance, and abnormal folding noise.

[0038] Specifically, the sidewall of the bowl 2 facing the shield 1 is provided with a guide surface 21. The upper sidewall of the shield 1 is aligned with the guide surface 21 to form a gap 22, with the gap 22 facing upward to prevent dust from entering from both sides. Furthermore, the flange 321 of the present invention passes through the gap 22 and abuts against both sides of the gap 22, thereby helping to block dust.

[0039] In addition, the flange 321 is provided with an abutment block 322 facing the inner sidewall of the shield 1. Furthermore, in this embodiment of the present application, the flange 321 is provided with two abutment blocks 322 on the inner sidewall of the shield 1. The design of the two abutment blocks 322 increases friction, facilitating the fixation of the flange 321 on the sealing ring 32 between the shield 1 and the bowl 2.

[0040] Furthermore, in this application, an angle of 30°-60° is formed between the main body of the sealing ring 32 and the flange 321. The guide surface 21 on the sidewall of the bowl 2 facing the shield 1 has an angle of 30°-60°. Specifically, in this embodiment, an angle of 45° is formed between the main body of the sealing ring 32 and the flange 321. Furthermore, the guide surface 21 on the sidewall of the bowl 2 facing the shield 1 has an angle of 45°. This facilitates the inverted attachment of the shield 1 to the bowl 2. Furthermore, the flange 321 rests snugly against the guide surface 21, securing the flange 321 of the sealing ring 32 between the bowl 2 and the shield 1.

[0041] Reference Figure 4 The sealing frame 31 is provided with a card block 312, and the shield 1 is provided with a card slot 11 for the card block 312 to engage. Specifically, the card block 312 is provided with a buckle structure, and cooperates with the card slot 11 to fix the sealing frame 31 and the shield 1.

[0042] Reference Figure 2The sealing ring 32 is made of soft rubber. This soft rubber is a thermoplastic vulcanized rubber, which has a certain degree of deformation and friction, improving the seal between the shield 1 and the bowl 2, thereby reducing the intrusion of dust particles into the folding movement surface. Furthermore, the sealing frame 31 is made of hard rubber. This hard rubber is polypropylene containing 30% glass fiber, which has a certain degree of rigidity. It not only limits the position of the sealing ring 32, but also helps to secure the sealing frame 31 to the shield 1.

[0043] The above describes the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-described embodiments. The above-described embodiments and the specification merely illustrate the principles of the present application.
