Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and in particular to a folding and sealing mechanism applied to vehicle exterior rearview mirrors. Background Technology

[0002] As a key component ensuring driving safety, the performance of vehicle exterior rearview mirrors directly affects the driver's field of vision and driving safety. During vehicle operation, exterior rearview mirrors frequently undergo folding and unfolding operations, which places extremely high demands on their connection structure and sealing performance.

[0003] Currently, many vehicle exterior rearview mirrors on the market have design flaws in the connection between the lens and the temple. Some products fail to adequately consider the rationality of the soft rubber design in this area; for example, they do not provide an appropriate material thickness below the interference fit, nor do they leave any clearance space at the bottom of the soft rubber. This causes the soft rubber to be unable to deform flexibly according to the actual situation when the rearview mirror rotates, thus creating additional resistance to the mirror body. This additional resistance not only causes problems with smooth folding but also increases folding resistance, which can easily lead to quality issues such as abnormal folding noises after long-term use, seriously affecting the user experience.

[0004] In terms of sealing performance, the sealing structure of traditional exterior rearview mirrors is difficult to meet the requirements of complex usage environments. Under harsh weather conditions, such as heavy rain and sandstorms, rainwater, dust, and other impurities can easily enter the interior through the connection gaps of the rearview mirror, corroding electronic components and mechanical structures. This leads to a decline in the electrical performance of the rearview mirror, rust and wear of mechanical parts, shortens the service life of the rearview mirror, and may even affect its normal function.

[0005] In summary, existing vehicle exterior rearview mirrors have many shortcomings in terms of connection structure and sealing performance. There is an urgent need for an innovative folding sealing mechanism to solve these problems, improve the overall performance and reliability of the rearview mirrors, and meet the growing demands of the automotive industry.

Detailed Implementation

[0026] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0027] like Figures 1-3As shown, a folding sealing mechanism for a vehicle exterior rearview mirror includes: a lens housing 1, on which a sealing unit 3 is provided that contacts a ball-and-socket cup 2; the sealing unit 3 includes: a mounting part 31, which is detachably mounted on the edge of the lens housing 1; a deformation part 32 is provided on the mounting part 31; a sealing contact part 33 that contacts the ball-and-socket cup 2 is provided on the deformation part 32; and clearance grooves 34 are provided on both sides of the mounting part 31 or on both sides of the deformation part 32. The sealing contact part 33 has a spherical cross-section. Multiple bending adaptation grooves 35 are provided at intervals on both sides of the sealing contact part 33. Multiple restoring auxiliary ribs 36 are provided in the clearance grooves 34 on the deformation part 32. The multiple restoring auxiliary ribs are arranged intersectingly. The mounting part 31 is embedded in the edge groove 11 of the lens housing 1. The mounting part 31 is mounted in the edge of the lens housing 1 by multiple pressure plates, which are fixed in the lens housing 1 by screws. The mounting portion 31 is provided with a rigid connector 12 that matches the shape of the edge of the lens housing 1. The rigid connector 12 is installed inside the edge of the lens housing 1. The rigid connector 12 is connected to the lens housing 1 by screws, snap-fit, or adhesive. The sealing contact portion 33 is a double-layer contact portion.

[0028] In the folding and sealing mechanism of the vehicle's exterior rearview mirror, each component plays a different role, working together to ensure the mechanism's optimal performance. The lens housing 1, as the foundational component of the entire mechanism, provides mounting positions and support for other components and is the key carrier connecting the entire folding and sealing mechanism to the other parts of the exterior rearview mirror.

[0029] The sealing unit 3 is the core component for achieving the sealing function, and the mounting part 31 serves to connect and fix the sealing unit. It is detachably installed on the edge of the lens housing 1, and the installation methods are various. It can be embedded in the edge groove 11 of the lens housing 1, or installed in the edge of the lens housing 1 by multiple pressure plates and fixed with screws. It can also be installed with the help of rigid connectors 12 that are adapted to the shape of the edge of the lens housing 1. The connection methods include screw connection, snap-fit, or adhesive. This makes the sealing unit easy and stable to install, ensuring that it will not loosen during vehicle operation and ensuring the normal operation of the sealing mechanism.

[0030] The deformable part 32 connects the mounting part 31 and the sealing contact part 33. When the rearview mirror is folded, the deformable part 32 can undergo elastic deformation, providing the sealing contact part 33 with the flexibility to adapt to the movement of the ball cup 2. The clearance groove 34 is provided on both sides of the mounting part 31 or on both sides of the deformable part 32. During the folding process, it provides space for the deformation of the deformable part 32, preventing damage to the sealing structure due to excessive compression and ensuring the normal use of the sealing unit.

[0031] The sealing contact part 33 is the key component that directly contacts the ball cup 2 to achieve a seal. Its cross-section is spherical, which allows it to better fit the ball cup 2, effectively reducing the possibility of rainwater, dust, and other impurities entering the rearview mirror, protecting internal electronic components and mechanical structures, and extending the service life of the rearview mirror. Multiple curved fitting grooves 35 spaced apart on both sides of the sealing contact part 33 enhance its adaptability to the ball cup 2 at different angles while ensuring a good seal. Even with frequent folding of the rearview mirror, a good seal can be maintained.

[0032] Multiple recovery auxiliary ribs 36 provided in the clearance groove 34 on the deformable part 32 play an important role in assisting the deformation part 32 to recover. The multiple recovery auxiliary ribs 36 are arranged in a cross pattern, which further enhances the recovery ability of the deformable part 32 after folding, ensures that the sealing contact part 33 can always make tight contact with the ball cup 2, maintain the sealing performance, and at the same time reduce material fatigue and damage caused by frequent folding.

[0033] The rigid connector 12 is installed inside the edge of the lens housing 1 and cooperates with the mounting part 31 to further enhance the connection stability between the mounting part 31 and the lens housing 1. Its various connection methods, such as screw connection, snap-fit ​​or adhesive connection, can be selected according to actual production needs, which improves the applicability of the product and production flexibility.

[0034] The sealing contact part 33 adopts a double-layer contact part design, which increases the reliability and stability of the contact, further improves the sealing effect, and can adapt to the usage needs of more different vehicle exterior rearview mirrors, thus improving the versatility and market adaptability of the folding sealing mechanism.

[0035] The ball cup 2, as a component that mates with the sealing contact part 33, interacts with the sealing contact part 33 during the folding and unfolding of the rearview mirror. The sealing contact part 33, relying on its special shape and structure, tightly fits the ball cup 2, achieving a good sealing effect and preventing the intrusion of external impurities. Through the coordinated work of its various components, the entire folding and sealing mechanism effectively solves the shortcomings of traditional vehicle exterior rearview mirrors in terms of connection structure and sealing performance, improving the overall performance and reliability of the rearview mirror and providing a better user experience for the driver.

[0036] The folding and sealing mechanism for the exterior rearview mirror of this application offers significant advantages. The specially designed sealing contact enhances sealing performance and reduces the intrusion of impurities. The clearance groove and recovery auxiliary ribs allow for proper deformation and recovery of the deformable part, ensuring a long-lasting and stable seal. Multiple installation methods make installation convenient and secure. The double-layer contact improves contact reliability, enhances the mechanism's versatility, and comprehensively improves the performance and reliability of the rearview mirror.

[0037] Work process

[0038] When the vehicle's exterior rearview mirror is folded, the deformation part 32 elastically deforms with the rotation of the mirror, and the clearance groove 34 provides deformation space to prevent damage to the sealing structure. Driven by the deformation part 32, the sealing contact part 33 maintains close contact with the ball cup 2, adapting to the movement trajectory of the ball cup 2 with its spherical cross-section and curved fitting groove 35, continuously performing its sealing function. When the rearview mirror is unfolded, the deformation part 32 quickly returns to its original shape under the action of the restoring auxiliary rib 36, ensuring that the sealing contact part 33 once again tightly fits the ball cup 2, maintaining sealing performance. Throughout the process, the mounting part 31, through various connection methods with the lens housing 1, firmly supports the sealing unit, and the rigid connector 12 further enhances the stability of the connection, ensuring the coordinated work of all components and achieving efficient operation of the vehicle's exterior rearview mirror folding and sealing mechanism.
