Description

Technical Field

[0001] This utility model relates to the field of rearview mirror assembly technology, specifically a rearview mirror production and assembly device. Background Technology

[0002] Rearview mirrors are important safety components installed on vehicles. They are mainly used to assist drivers in observing road conditions behind, to the sides, and in part of the front of the vehicle, expanding the field of vision, reducing blind spots, and ensuring driving safety. Structurally and functionally, rearview mirrors are usually composed of a mirror surface, a frame, and an adjustment mechanism. The mirror surface is generally a convex mirror (some models are equipped with a flat mirror). The convex mirror uses the light-diffusing effect to allow the driver to see a wider range.

[0003] In the production and assembly of automotive rearview mirrors, existing clamping devices often suffer from fixed clamping force and lack adaptive adjustment capabilities, making it difficult to accommodate the stress requirements of various materials such as lenses and mirror housings. This can easily lead to problems such as broken glass lenses, deformed plastic mirror housings, or displacement of metal brackets. At the same time, when rigid grippers come into contact with curved parts, stress concentration is obvious, the buffering effect is insufficient, and the force cannot be dynamically adjusted according to different processes such as pre-positioning, fastening, and inspection, resulting in low assembly accuracy and high scrap rate. Utility Model Content

[0004] The purpose of this invention is to provide a rearview mirror production and assembly device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a rearview mirror production and assembly device, including a base plate, two mounting plates fixedly mounted on the top of the base plate; a first elastic element fixedly mounted on one side of the mounting plate, the first elastic element being elliptical in shape, and two sets of second elastic elements fixedly mounted on the inner wall of the first elastic element, each set containing two second elastic elements, the other ends of the second elastic elements also being mounted on the inner wall of the first elastic element; the second elastic elements being V-shaped; a reset element disposed between adjacent upper and lower second elastic elements, the reset element also being V-shaped; and a clamping block fixedly mounted on the outer wall of the first elastic element.

[0006] Furthermore, a damper and a tension spring are fixedly installed between the mounting plate and the clamping block, with the tension spring sleeved on the outer wall of the damper.

[0007] Furthermore, the cross-section of the clamping block is set to trapezoidal, the inclined surface of the clamping block faces upward, the inclined surface of the clamping block is provided with an installation groove, and multiple guide rollers are rotatably arranged on the installation groove.

[0008] Furthermore, the side of the clamp that contacts the rearview mirror housing is integrally formed with a rubber layer.

[0009] Furthermore, the outer wall of the guide roller is integrally formed with a rubber soft layer.

[0010] Furthermore, a guide groove is provided on the top of the base plate, and a slider adapted to the guide groove is installed on the bottom of the base plate.

[0011] Furthermore, the clamping block is made of stainless steel.

[0012] Furthermore, the guide rollers are arranged in a linear array.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, during the production and assembly of the rearview mirror, an external force is applied to the clamping block and transmitted to the first elastic element of the elliptical spring steel, causing it to deform. This causes the second elastic element of the inner wall V-shaped elastic element to change its angle, and the adjacent V-shaped reset elements cooperate in deformation. Through the coordinated deformation of the elastic elements, the shape of the outer shell is adapted and clamping force is provided. After the external force is removed, each elastic element is reset by the elasticity of the spring steel. This coordinated deformation can adaptively adjust the clamping force according to the materials of the lens, mirror shell, metal bracket, etc., to avoid glass breakage, plastic deformation, and metal displacement.

[0015] 2. In this utility model, the clamping block has a trapezoidal cross-section, and its inclined surface is provided with an installation groove and multiple guide rollers are rotatably arranged. When placing or removing rearview mirror parts, the guide rollers can play a guiding role, making it easier for the parts to be aligned with the installation position. At the same time, it reduces the friction between the parts and the clamping block, making operation easier and preventing damage to the surface of the parts due to friction, thus improving product quality. Furthermore, the linear array of guide rollers can ensure uniform force and improve clamping stability. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution:

[0023] See Figures 1-4 As shown, a rearview mirror manufacturing and assembly device includes a base plate 1, two mounting plates 2 fixedly mounted on the top of the base plate 1; a first elastic element 3 fixedly mounted on one side of the mounting plate 2, the first elastic element 3 being elliptical in shape, and two sets of second elastic elements 4 fixedly mounted on the inner wall of the first elastic element 3, each set containing two second elastic elements 4, the other ends of the second elastic elements 4 also being mounted on the inner wall of the first elastic element 3; the second elastic elements 4 being V-shaped; a reset element 5 disposed between adjacent second elastic elements 4, the reset element 5 also being V-shaped; and a clamping block 8 fixedly mounted on the outer wall of the first elastic element 3.

[0024] During the rearview mirror manufacturing and assembly process, when the rearview mirror housing needs to be clamped, an external force is applied to the clamping block 8, which transmits the force to the first elastic element 3. Since the first elastic element 3 is elliptical and made of spring steel, it is elastic and deforms under force. The deformation of the first elastic element 3 drives the second elastic element 4 on the inner wall. The second elastic element 4 is V-shaped, and its V-angle changes under force. Simultaneously, the reset element 5 between adjacent second elastic elements 4, also V-shaped and made of spring steel, also deforms in coordination. Through the coordinated deformation of these elastic elements, the rearview mirror housing is adapted to its shape and a suitable clamping force is provided. When the external force is removed, the first elastic element 3, the second elastic element 4, and the reset element 5 return to their original shape due to the elasticity of the spring steel.

[0025] Through the coordinated elastic deformation of the first elastic element 3, the second elastic element 4, and the reset element 5, the clamping force can be adaptively adjusted according to the force requirements of different materials such as lenses, lens shells, and metal brackets, effectively avoiding problems such as glass lens breakage, plastic lens shell deformation, and metal bracket displacement.

[0026] When the elastic component structure comes into contact with the curved component, it can disperse stress, provide good buffering effect, and reduce the risk of component damage due to stress concentration.

[0027] See Figure 2-3 A damper 6 and a tension spring 7 are fixedly installed between the mounting plate 2 and the clamping block 8. The tension spring 7 is sleeved on the outer wall of the damper 6.

[0028] The damper 6 can suppress the instantaneous impact of the clamping block 8, making the clamping process smooth and reducing rigid collision damage to the parts. The tension spring 7, sleeved outside the damper 6, provides additional elastic support, enhances the buffering capacity, disperses stress, and prevents excessive local force. After the external force is removed, the two work together to make the clamping block 8 return to its position smoothly, avoiding positioning deviation. Their cooperation can also reduce the instantaneous stress peak of the elastic element, share the load, and extend the fatigue life of the entire clamping system. They can also play a role in different processes. When pre-positioning, the damper 6 makes the clamping block 8 slowly contact to avoid displacement. When tightening, the tension spring 7 provides a stable pre-tightening force, and during testing, it ensures the reliability of the measurement benchmark.

[0029] See Figure 3 The cross-section of the clamping block 8 is set as a trapezoid, the inclined surface of the clamping block 8 faces upward, the inclined surface of the clamping block 8 is provided with an installation groove, and multiple guide rollers 9 are rotatably arranged on the installation groove.

[0030] The clamping block 8 has a trapezoidal cross-section, and its inclined surface is provided with an installation groove and multiple guide rollers 9 are rotatably arranged. When placing or removing rearview mirror parts, the guide rollers 9 can play a guiding role, making it easier for the parts to be aligned with the installation position. At the same time, it reduces the friction between the parts and the clamping block 8, making operation easier and preventing damage to the surface of the parts due to friction, thus improving product quality. In addition, the linear array of guide rollers 9 can ensure uniform force and improve clamping stability.

[0031] See Figure 1 The side of the clamp 8 that contacts the rearview mirror housing is integrally formed with a rubber layer 12.

[0032] The rubber layer 12 integrally formed on the side of the clamping block 8 that contacts the rearview mirror housing can increase friction, making the clamping block 8 more secure in clamping the rearview mirror housing and preventing it from sliding or shifting during assembly. At the same time, the rubber layer 12 is elastic and can play a buffering role, avoiding rigid contact between the clamping block 8 and the rearview mirror housing, preventing damage or scratches to the surface of the rearview mirror housing, and protecting the appearance and quality of the rearview mirror housing.

[0033] See Figure 1 The outer wall of the guide roller 9 is integrally formed with a rubber soft layer.

[0034] The rubber soft layer integrally formed on the outer wall of the guide roller 9 can increase the friction with the surface of the rearview mirror components, preventing the components from slipping during movement. At the same time, the elasticity of the rubber soft layer can buffer the impact between the guide roller 9 and the components, avoiding scratches or indentations, protecting the surface quality of the components. Furthermore, the flexible contact of the rubber soft layer can adapt to components with different curved shapes, improving the compatibility and stability of the guiding process.

[0035] See Figure 1 The top of the base plate 1 is provided with a guide groove 10, and the bottom of the base plate 1 is provided with a slider 11 that is compatible with the guide groove 10.

[0036] The guide groove 10 at the top of the base plate 1 is adapted to the slider 11 at the bottom, which allows the base plate 1 to slide precisely along the direction of the guide groove 10 during movement, improving the stability and guidance of the device movement, avoiding deviation or shaking, ensuring the positional accuracy of components such as the clamping block 8, and facilitating the installation and docking of the base plate 1 with other equipment or components, thereby improving the integration and reliability of the entire assembly device.

[0037] See Figure 1 The material of clamp 8 is set to stainless steel.

[0038] The clamping block 8 is made of stainless steel, which has high strength and corrosion resistance. It can withstand large clamping forces without easily deforming, ensuring the stability of clamping performance during long-term use. At the same time, its corrosion resistance can adapt to complex production environments, reduce the frequency of failure and maintenance caused by rust and other problems of the clamping block 8, and extend the service life of the device.

[0039] See Figure 1 The guide rollers 9 are arranged in a linear array.

[0040] The guide rollers 9 are arranged in a linear array, which makes the guiding effect of the inclined surface of the clamping block 8 more uniform and consistent. When placing or removing rearview mirror parts, it can ensure that the parts move smoothly along a straight line and avoid deviation or jamming caused by uneven guidance. At the same time, the linear array layout can increase the contact area with the parts, disperse the force, and improve the stability and reliability of the clamping process.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
