Description

Technical Field

[0001] This utility model relates to the field of automotive exterior rearview mirrors, specifically an adjustment component for automotive rearview mirror folding mechanisms. Background Technology

[0002] As automation increases, manual adjustment mechanisms for car rearview mirrors have gradually been phased out, while automatic adjustment mechanisms are becoming more widely used. In rearview mirror folders with automatic adjustment functions, a spring is fitted around the outer ring of the mounting shaft to ensure structural compactness and return capability. However, with prolonged use, it has been found that the direction of the spring force changes, resulting in uneven force on both ends of the spring. During repeated folding, the internal structure of the folder wears unevenly, which can easily cause problems such as abnormal folding noise and shortened service life. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an adjustment component for a car rearview mirror folding device that stabilizes the spring force and thus avoids inconsistent wear of the internal structure of the folding device after the direction of the spring force changes.

[0004] The technical solution adopted by this utility model to solve the above problems is an adjustment assembly for a car rearview mirror folding device, including a mounting shaft and a central connector. The central connector is rotatably connected to the mounting shaft, and the central connector is axially limited and movable in the middle section of the mounting shaft. One end of the mounting shaft is fixedly connected to a limiting mounting piece. A spring is provided between the limiting mounting piece and the central connector. One end of the spring abuts against the limiting mounting piece, and the other end of the spring abuts against the central connector through a floating ring. The floating ring is sleeved on the mounting shaft, and the floating ring is circumferentially limited and connected to the outer ring of the mounting shaft.

[0005] Compared with the prior art, the advantages of this utility model are as follows: In the folding device, the function of the spring in the original structure is not changed, ensuring that the spring has the function of making the internal structure of the folding device compact and resetting. In the original structure, the other end of the spring abuts against the central connecting member. During the folding process, the central connecting member rotates relative to the spring, which can easily cause the spring to deform and change the direction of the elastic force. After long-term use, this can easily cause uneven wear due to uneven force. In this utility model, the floating ring design separates the central connecting member from the spring and limits the floating ring circumferentially. Therefore, when the central connecting member rotates, the floating ring will not rotate synchronously, thus ensuring the stability of the spring, avoiding spring deformation, and thus ensuring the stability of the elastic force. It is less likely to cause the elastic force deviation and uneven wear of the internal structure. Furthermore, because the spring is always in a compressed state, the wear during the folding device's operation and the up and down floating motion of the central connecting member are compensated by the spring's extension, thus achieving a vibration-proof effect and ensuring the stability of the folding device's operation.

[0006] As an improvement of this utility model, it also includes a housing, which abuts against the end of the mounting shaft where a limiting mounting piece is provided. The housing has multiple circumferential limiting grooves on the side near the mounting shaft, and these grooves are evenly distributed along the circumference of the mounting shaft. The floating ring has multiple circumferential limiting blocks distributed in the same circumferential direction as the circumferential limiting grooves. The width of the circumferential limiting groove is equal to the width of the circumferential limiting block. Through this improvement, the circumferential limiting of the circumferential limiting block is achieved through the connection between the circumferential limiting groove and the circumferential limiting block, thereby achieving circumferential limiting of the floating ring. Simultaneously, the design that the width of the circumferential limiting groove is equal to the width of the circumferential limiting block ensures that the circumferential limiting block will not rotate synchronously when the central connecting member rotates, thus ensuring the stability of the spring during use.

[0007] As an improvement of this utility model, the circumferential limiting block is axially connected to the circumferential limiting groove along the mounting shaft. Through this improvement, the axial movement of the floating ring is ensured, that is, the up and down floating of the floating ring, thereby ensuring the abutment effect of the spring on the centralized connecting part and ensuring the compact structure and structural reset function of the spring in the folding device.

[0008] As an improvement of this utility model, the side of the circumferential limiting block near the limiting mounting piece is tapered. With this improvement, when assembling the folding device, before installing the housing, the floating ring can rotate freely along the circumferential direction, and the fit between the circumferential limiting block and the circumferential limiting groove is relatively tight. Moreover, the circumferential limiting groove is oriented when fixed. If the position of the circumferential limiting block fails to match the circumferential limiting groove when installing the housing, it is easy to cause installation failure. Therefore, by designing the side of the circumferential limiting block near the limiting mounting piece to be tapered, the circumferential limiting block is guided, making the installation of the circumferential limiting block and the circumferential limiting groove more convenient and smoother.

[0009] As an improvement of this utility model, the floating ring is provided with a stabilizing spring groove on the side near the limiting mounting plate for accommodating the other end of the spring. Through this improvement, the connection stability between the other end of the spring and the floating ring is guaranteed.

[0010] As an improvement of this utility model, the inner sidewall of the stabilizing spring groove abuts against the mounting shaft on the side closest to the mounting shaft. Through this improvement, the coaxiality of the stabilizing spring groove and the mounting shaft is ensured, thereby guaranteeing the coaxiality of the spring with the mounting shaft when the spring is installed in the stabilizing spring groove, so as to ensure the axiality of the spring's elastic force and reduce the probability of deflection.

[0011] As an improvement of this utility model, a floating ring mounting groove for mounting the end of the floating ring is provided between the side of the centralized connector near the limiting mounting plate and the mounting shaft. Through this improvement, the connection stability between the centralized connector and the floating ring is ensured, and the centralized connector is prevented from separating from the floating ring during rotation.

[0012] As an improvement of this utility model, the inner ring of the limiting mounting piece abuts against the mounting shaft, the outer ring of the limiting mounting piece is provided with a bent ring facing the floating ring, and a limiting spring groove for accommodating one end of the spring is formed between the limiting mounting piece and the mounting shaft. Through this improvement, the connection stability between one end of the spring and the limiting mounting piece is ensured.

[0013] As an improvement of this utility model, both ends of the spring are provided with a coil ring on the same plane. Through this improvement, the circumferential integrity of the position where the spring abuts against the floating ring and the limiting mounting piece is guaranteed, and the circumferential uniformity of the spring force is guaranteed, so as to avoid the spring deformation caused by poor force balance.

Detailed Implementation

[0020] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0021] like Figure 1 As shown, an adjustment assembly for a car rearview mirror folding mechanism includes a mounting shaft 1 and a central connector 2. The central connector 2 is rotatably connected to the mounting shaft 1 and is axially limited and movable along the middle section of the mounting shaft 1. One end of the mounting shaft 1 is fixedly connected to a limiting mounting piece 3. A spring 4 is provided between the limiting mounting piece 3 and the central connector 2. One end of the spring 4 abuts against the limiting mounting piece 3, and the other end of the spring 4 abuts against the central connector 2 through a floating ring 5. The floating ring 5 is sleeved on the mounting shaft 1 and is circumferentially limited and connected to the outer ring of the mounting shaft 1. During the folding mechanism operation, the central connector 2 not only rotates circumferentially but also floats up and down.

[0022] like Figure 1-3As shown, it also includes a housing 6, which abuts against one end of the mounting shaft 1 where a limiting mounting piece 3 is provided. The housing 6 has three circumferential limiting grooves 6.1 on the side near the mounting shaft 1, and the three circumferential limiting grooves 6.1 are evenly distributed along the circumference of the mounting shaft 1. The floating ring 5 has three circumferential limiting blocks 5.1 distributed in the same circumferential direction as the three circumferential limiting grooves 6.1. The width of the circumferential limiting groove 6.1 is equal to the width of the circumferential limiting block 5.1. The circumferential limiting block 5.1 is movably connected to the circumferential limiting groove 6.1 along the axial direction of the mounting shaft 1. The side of the circumferential limiting block 5.1 near the limiting mounting piece 3 is conical. By connecting the circumferential limiting groove 6.1 with the circumferential limiting block 5.1, the circumferential limiting of the circumferential limiting block 5.1 is achieved, thereby achieving the circumferential limiting of the floating ring 5. At the same time, the design that the width of the circumferential limiting groove 6.1 is equal to the width of the circumferential limiting block 5.1 ensures that the circumferential limiting block 5.1 will not rotate synchronously when the central connecting piece 2 rotates, thus ensuring the stability of the spring 4 during use.

[0023] like Figure 1 , Figure 3 , Figure 4 As shown, the floating ring 5 has a stabilizing spring groove 5.2 on the side near the limiting mounting piece 3 for accommodating the other end of the spring 4. The inner sidewall of the stabilizing spring groove 5.2 abuts against the mounting shaft 1 on the side near the mounting shaft 1. The central connector 2 has a floating ring mounting groove 2.1 between the side near the limiting mounting piece 3 and the mounting shaft 1 for mounting the end of the floating ring 5. The inner ring of the limiting mounting piece 3 abuts against the mounting shaft 1, and the outer ring of the limiting mounting piece 3 has a bent ring 3.1 facing the floating ring 5. A limiting spring groove 3.2 for accommodating one end of the spring 4 is formed between the limiting mounting piece 3 and the mounting shaft 1. The side of the limiting mounting piece 3 away from the spring 4 abuts against the housing 6.

[0024] like Figure 1 , Figure 5 As shown, both ends of the spring 4 are provided with a coil ring 4.1 on the same plane. Through the design of the floating ring 5 and the coil ring 4.1, the elastic force of the spring 4 is designed to be uniform along the axial direction of the mounting shaft 1, ensuring the uniformity of the elastic force and the stability of the force, thereby ensuring the long-term quality of the folding device.

[0025] The design of the floating ring 5 separates the central connector 2 from the spring 4 and limits the circumferential movement of the floating ring 5. As a result, when the central connector 2 rotates, the floating ring 5 will not rotate synchronously, thus ensuring the stability of the spring 4, preventing the spring 4 from deforming, and thus ensuring the stability of the elastic force. This also makes it less likely to cause deviations in the elastic force or inconsistent wear of the internal structure.

This utility model is not limited to the above embodiments, and variations in its specific structure are permitted. All changes made within the scope of the independent claims of this utility model are also within the scope of protection of this utility model.
