Description

Technical Field

[0001] This invention relates to the field of rearview mirror technology, and more particularly to a rearview mirror. Background Technology

[0002] In existing rearview mirror angle adjustment structures, the oscillating element and the lever are often connected by a spring to achieve angle adjustment. However, due to unreasonable connection relationship and pressure angle design between the spring, the oscillating element, and the lever, some structures are prone to excessive force or improper direction on the spring during adjustment. This can cause the spring to exert unnecessary pressure on the lens or related components, resulting in component wear. It may also be accompanied by problems such as adjustment jamming and insufficient stability. Summary of the Invention

[0003] The technical problem to be solved by the embodiments of the present invention is that, in the rearview mirror angle adjustment structure, due to the unreasonable design of the connection between the spring and the swinging component and the lever, as well as the pressure angle, the spring is prone to squeezing the lens or related components, causing wear and tear, and the adjustment stability is insufficient.

[0004] To address the aforementioned problems, this invention discloses a rearview mirror. By rationally configuring the connection relationship between the connector, housing, and lever, and optimizing the relative positions and pressure angles of each axis, excessive pressure of the spring on the lens is avoided, component wear is reduced, and adjustment stability is improved.

[0005] This invention provides a rearview mirror, comprising a housing, a swing assembly, a lever, and a connector mounted within the housing; the connector is connected to both the housing and the lever; the swing assembly is rotatably mounted on the housing about a first axis, and a support column is provided near the lever; the lever is rotatably mounted on the housing about a second axis, and rotates between an upper and lower position around the second axis; the height of the second axis is less than the height of the first axis; wherein, when the lever is in the upper position, the support column is connected to the mirror body; when the lever rotates from the upper position to the lower position, the height of the connection point between the connector and the lever rises, causing the swing assembly to rotate around the first axis.

[0006] A further technical solution is that the connector includes a fixing part, a buffer part, and a rotating part. The fixing part is connected to the housing and located below the first axis. The rotating part is rotatably connected to the lever. The buffer part is connected between the fixing part and the rotating part.

[0007] A further technical solution is that the buffer part includes a first arm and a second arm, the first arm is close to the fixed part, the second arm is close to the rotating part, and the length of the first arm is shorter than the length of the second arm.

[0008] A further technical solution is that the pressure angle between the connector and the lever is less than 75 degrees, the rotating part is mounted on the lever around the third axis, the first axis and the second axis form a first line segment, the second axis and the third axis form a second line segment, and the pressure angle is formed between the first line segment and the second line segment.

[0009] A further technical solution is that the housing is provided with a groove, and the lever is disposed in the groove.

[0010] A further technical solution is that the housing is also provided with a limiting member, which is disposed in the groove; when the lever is in the lower position, the lever is connected to the limiting member.

[0011] A further technical solution is that when the lever is in the lower and upper positions respectively, the rotation angle of the lever is less than or equal to 60 degrees.

[0012] A further technical solution includes an adjustment bracket, which is detachably connected to the swing assembly.

[0013] A further technical solution is that the adjusting bracket includes a connecting arm and a first movable part, the first movable part being movably connected to the connecting arm, and the second movable part being detachably connected to the swing assembly.

[0014] A further technical solution is that the adjusting bracket further includes a second movable part, which is movably connected to the connecting arm.

[0015] Compared with the prior art, the technical effects achieved by the embodiments of the present invention include:

[0016] By setting the relative positions of each axis and the connection relationship of the connecting parts, the lever can stably drive the swing assembly to adjust when it rotates, avoiding the lens squeezing problem caused by unreasonable component linkage and reducing the risk of component damage.

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Similar component reference numerals in the drawings represent similar components. Obviously, the embodiments described below are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0026] It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0027] It should also be understood that the terminology used in this specification of embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of the invention. As used in this specification of embodiments of the invention and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0028] See Figures 1-4This invention provides a rearview mirror. The rearview mirror includes a housing 1, a swing assembly 2 installed within the housing 1, a lever 3, and a connector 4. The connector 4 is connected to both the housing 1 and the lever 3. The swing assembly is rotatably mounted on the housing 1 around a first axis L1, and a support column 21 is provided near the lever 3. The lever 3 is rotatably mounted on the housing 1 around a second axis L2, and rotates between an upper and lower position around the second axis L2. The height of the second axis L2 is less than the height of the first axis L1. When the lever 3 is in the upper position, the support column 21 is connected to the mirror body 6. When the lever 3 rotates from the upper position to the lower position, the height of the connection point between the connector 4 and the lever 3 rises, causing the swing assembly 2 to rotate around the first axis L1. Specific descriptions of each component are as follows:

[0029] In this embodiment, the housing 1 provides a mounting carrier for each component, corresponding to the outer shell in the product; the swing assembly 2 includes a swinging member that can rotate around the first axis L1, and a support column 21 is provided at the bottom of the swing assembly 2 near the lever 3 for abutting the lens body 6. Typically, the lens body 6 is provided with a buffer or buffer pad corresponding to the support column 21 to prevent the support column 21 from causing damage to the lens body 6; the lever 3 is rotatably mounted on the housing 1 around the second axis L2 and can switch between the upper and lower positions, and the height of the second axis L2 is lower than the height of the first axis L1; the connecting member 4 connects the housing 1 and the lever 3 respectively to realize the transmission of force, corresponding to the spring-type structure in the product.

[0030] By setting the relative positions of each axis and the connection relationship of the connector 4, the lever 3 can stably drive the swing assembly 2 to adjust when it rotates, thus avoiding the lens squeezing problem caused by unreasonable component linkage and reducing the risk of component wear.

[0031] See also Figures 1-4 In this embodiment, the connector 4 includes a fixing part 41, a buffer part 42, and a rotating part 43. The fixing part 41 is connected to the housing 1 and located below the first axis L1. The rotating part 43 is rotatably connected to the lever 3. The buffer part 42 is connected between the fixing part 41 and the rotating part 43.

[0032] Specifically, the fixing part 41 is connected to the housing 1 and located below the first axis L1, providing stable support for the connector 4; the rotating part 43 is rotatably connected to the lever 3 and moves with the lever 3. For example, when the lever 3 rotates from the upper position to the lower position, the rotating part 43 rotates around the second axis L2, and the height of the rotating part 43 gradually increases; the buffer part 42 connects the fixing part 41 and the rotating part 43, and is usually a U-shaped structure, which plays a role in buffering and transmitting force.

[0033] By dividing the connector 4 into three parts—fixed, buffered, and rotating—the force transmission path is optimized. The buffer part 42 can alleviate the instantaneous stress during adjustment, reduce the hard compression on the lens and other components, and improve the structural durability.

[0034] Furthermore, the buffer portion 42 includes a first arm 421 and a second arm 422, the first arm 421 being close to the fixed portion 41, the second arm 422 being close to the rotating portion 43, and the length of the first arm 421 being shorter than the length of the second arm 422.

[0035] Specifically, the buffer part 42 has a U-shaped structure. The cooperation between the short arm and the long arm makes the buffer part 42 more evenly stressed, avoiding deformation or breakage caused by local stress concentration, reducing lens squeezing problems caused by damage to the connector 4, and extending the service life of the component.

[0036] Furthermore, the pressure angle θ between the connector 4 and the lever 3 is less than 75 degrees, the rotating part 43 is mounted on the lever 3 around the third axis L3, the first axis L1 and the second axis L2 form a first line segment, the second axis L2 and the third axis L3 form a second line segment, and the pressure angle θ is formed between the first line segment and the second line segment.

[0037] Specifically, the pressure angle θ is formed by the angle between the first line segment formed by the first axis L1 and the second axis L2, and the second line segment formed by the second axis L2 and the third axis L3. As the lever 3 rotates from the upper position to the lower position, the pressure angle θ gradually increases.

[0038] A pressure angle θ less than 75 degrees can improve the stress state of connector 4, avoid unreasonable elastic force direction caused by excessive angle, and reduce indirect compression of the lens.

[0039] Furthermore, the housing 1 is provided with a groove 11, and the lever 3 is disposed in the groove 11.

[0040] The groove 11 provides protection and limit for the lever 3. The lever 3 is installed in the groove 11 to reduce the impact of external collisions on the lever 3 and avoid abnormal force on the connector 4 due to the displacement of the lever 3.

[0041] Furthermore, the housing 1 is also provided with a limiting member 12, which is disposed in the groove 11; when the lever 3 is in the lower position, the lever 3 is connected to the limiting member 12.

[0042] Specifically, the limiting member 12 is a protruding structure in the groove 11. When the lever 3 is in the lower position, the limiting member 12 abuts against the lever 3, preventing the connecting member 4 from deforming excessively due to excessive rotation of the lever 3. This reduces lens compression and component wear caused by excessive adjustment, improves the stability of the adjustment process, and further prevents the lens from being excessively compressed by the support column 21.

[0043] Furthermore, when the lever 3 is in the lower and upper positions respectively, the rotation angle of the lever 3 is less than or equal to 60 degrees.

[0044] Specifically, controlling the rotation angle can reduce the deformation of the connector 4, avoid the surge in elasticity caused by excessive rotation, thereby reducing the risk of squeezing the lens, while ensuring adjustment accuracy.

[0045] Furthermore, it also includes an adjustment bracket 5, which is detachably connected to the swing assembly 2.

[0046] Specifically, the detachable adjustable bracket 5 enhances the adaptability of the structure, making it easy to replace lenses according to different lens specifications, avoiding squeezing problems caused by mismatch between the bracket and the lens, and improving the flexibility of use.

[0047] Furthermore, the adjusting bracket 5 includes a connecting arm 51 and a first movable part 52, the first movable part 52 being movably connected to the connecting arm 51, and the second movable part 53 being detachably connected to the swing assembly 2.

[0048] Specifically, the first movable part 52 and the connecting arm 51 are connected by a ball joint. The first movable part 52 has a spherical structure, and one end of the connecting arm 51 has a recessed structure that encloses the first movable part 52, so that the spherical structure can rotate around the center of the ball in multiple directions, thereby driving the swing component 2 connected to the first movable part 52 to achieve multi-angle movement and improving the flexibility of the lens body 6 angle adjustment.

[0049] Furthermore, the adjusting bracket 5 also includes a second movable part 53, which is movably connected to the connecting arm 51.

[0050] Specifically, the second movable part 53 is installed on the vehicle mounting position. The second movable part 53 is connected to the connecting arm 51 by a ball joint. The second movable part 53 has a spherical structure. The other end of the connecting arm 51 has a recessed structure that encloses the second movable part 53, so that the spherical structure can rotate around the center of the sphere in multiple directions. Since the spherical structure is fixed inside the vehicle, the connecting arm 51 drives the first movable part 52 to achieve multi-angle movement, further improving the flexibility of the lens body 6 angle adjustment.
