Rearview mirror structure and vehicle

Abstract

This disclosure relates to a rearview mirror structure and a vehicle. The rearview mirror structure includes: a mirror holder, comprising a mirror holder body and an elastic edge member, the elastic edge member being connected to the edge of the mirror holder body in a first direction, and the elastic edge member and the mirror holder body forming a recessed mirror groove in a second direction; a rearview mirror, disposed in the mirror groove, with the back of the rearview mirror connected to the mirror holder body, the edge of the rearview mirror abutting against the elastic edge member in the first direction; wherein the first direction and the second direction intersect. By forming a mirror groove with the elastic edge member and the mirror holder body, the edge gap required by traditional rigid mirror holders is eliminated, allowing the edge of the rearview mirror to be close to the elastic edge member, which can significantly expand the effective mirror area; in addition, compared with traditional rigid mirror holders, the elastic edge member is made of elastic material, eliminating the need to consider outward convex rounded corners, allowing the thickness to be made as thin as possible, further increasing the mirror-to-body ratio of the rearview mirror.

Description

Technical Field

[0001] This disclosure relates to the field of vehicle technology, and more specifically, to a rearview mirror structure and a vehicle. Background Technology

[0002] In related technologies, the mirror holder of vehicle rearview mirrors is generally made of hard injection molding. According to the mandatory requirements of the regulations on motor vehicle rearview mirrors for the convex rounded corners, the rounded corners of the exposed surface of the mirror holder need to be designed to be ≥2.5mm. After adding the draft angle required by the injection molding process, the actual material thickness of the edge area of ​​the mirror holder is usually ≥3mm.

[0003] In addition, to prevent the lens from cracking due to dimensional interference between the lens holder and the lens caused by thermal expansion and contraction (especially in low-temperature winter environments), a safety gap of ≥0.2mm should be reserved between the lens holder and the lens edge to absorb tolerance fluctuations.

[0004] Therefore, due to the combined effects of the thickness of the lens holder edge and the safety gap, the minimum distance from the outer edge of the lens holder to the edge of the lens reaches more than 3.2mm, which severely restricts the expansion of the effective visual area of ​​the lens and results in a small lens-to-body ratio. Utility Model Content

[0005] To overcome the problems existing in the related technologies, this disclosure provides a rearview mirror structure and a vehicle to solve the technical problems existing in the related technologies.

[0006] According to an embodiment of this disclosure, a rearview mirror structure is provided, the rearview mirror structure comprising:

[0007] A mirror holder includes a mirror holder body and an elastic edge member, the elastic edge member being connected to the edge of the mirror holder body in a first direction, and the elastic edge member and the mirror holder body forming a recessed groove in a second direction.

[0008] A rearview mirror is disposed in the mirror groove, and the back of the rearview mirror is connected to the mirror holder body. The edge of the rearview mirror in the first direction abuts against the elastic edge member in the first direction.

[0009] The first direction and the second direction are intersecting.

[0010] In some embodiments, the resilient edge member includes a base and a protrusion;

[0011] The base is connected to the edge of the lens holder body in a first direction, and the protrusion is connected to the base and extends along a second direction;

[0012] The edge of the rearview mirror along the first direction abuts against the protrusion in the first direction;

[0013] The second direction is the thickness direction of the rearview mirror.

[0014] In some embodiments, the lens holder body has a groove recessed along the edge of the first direction in the first direction, and the base is disposed in the groove.

[0015] In some embodiments, the protrusion includes a first side surface away from the rearview mirror along the first direction, the base includes a second side surface away from the mirror holder body along the first direction, the mirror holder body has an edge surface formed at the edge in the first direction, the first side surface and the second side surface are smoothly connected, and the second side surface and the edge surface are smoothly connected.

[0016] In some embodiments, the base includes a third side surface adjacent to the rearview mirror along the second direction, and the mirror holder body includes a fourth side surface adjacent to the rearview mirror along the second direction, wherein the third side surface and the fourth side surface are smoothly connected.

[0017] In some embodiments, the length of the protrusion extending in the second direction is not less than the thickness of the rearview mirror; and / or, the thickness of the protrusion in the first direction is not less than 0.33 mm; and / or, the Shore hardness of at least the protrusion of the resilient edge member is not greater than 60 HA.

[0018] In some embodiments, the base and the protrusion are constructed as an integrally formed structure.

[0019] In some embodiments, the mirror holder body and the elastic edge member are formed using a two-color injection molding process.

[0020] In some embodiments, the rearview mirror structure further includes an adhesive layer, through which the rearview mirror is bonded to the mirror holder body.

[0021] According to an embodiment of this disclosure, a vehicle is also provided, the vehicle including the aforementioned rearview mirror structure.

[0022] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects: First, by forming a mirror groove with the elastic edge member and the mirror holder body, the edge gap required by the traditional rigid mirror holder is eliminated, so that the edge of the rearview mirror can be close to the elastic edge member, which can significantly expand the effective mirror area; In addition, compared with the traditional rigid mirror holder, the elastic edge member is made of elastic material, so there is no need to consider making outward convex rounded corners, so the thickness can be made as thin as possible, further increasing the mirror ratio of the rearview mirror.

[0023] Secondly, the flexible edge component can absorb the dimensional tolerance between the mirror holder and the rearview mirror during assembly by deforming, thus avoiding the risk of the rearview mirror chipping at the edge.

[0024] In addition, the elasticity of the flexible edge component allows the rearview mirror to be positioned by slight pressure during installation, reducing the reliance on high-precision robots for positioning and lowering production line costs.

[0031] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0032] In this disclosure, unless otherwise stated, the directional terms "first direction" and "second direction" refer to two intersecting directions, as detailed in the following references. Figure 2 As shown. The terms used, such as "first" and "second," are only used to distinguish one element from another and do not indicate any order or importance.

[0033] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0034] Reference Figure 1 and Figure 2 As shown, this disclosure provides a rearview mirror structure, which includes a mirror holder 1 and a rearview mirror 2. The mirror holder 1 includes a mirror holder body 11 and an elastic edge member 12. The elastic edge member 12 is connected to the edge of the mirror holder body in a first direction A, and the elastic edge member 12 and the mirror holder body 11 form a recessed mirror groove 10 in a second direction B. The rearview mirror 2 is disposed in the mirror groove 10, and the back of the rearview mirror 2 is connected to the mirror holder body 11. The edge of the rearview mirror 2 in the first direction A abuts against the elastic edge member 12 in the first direction A; wherein the first direction A and the second direction B are intersecting.

[0035] In the above technical solution, firstly, the elastic edge member 12 and the mirror holder body 11 form a mirror groove 10, eliminating the edge gap required by the traditional hard mirror holder, so that the edge of the rearview mirror 2 can be close to the elastic edge member 12, which can significantly expand the effective mirror area; in addition, compared with the traditional hard mirror holder, the elastic edge member 12 is made of elastic material, so there is no need to consider making outward convex rounded corners, so the thickness can be made as thin as possible, further increasing the mirror ratio of the rearview mirror 2.

[0036] Secondly, the elastic edge piece 12 can absorb the dimensional tolerance between the mirror support 1 and the rearview mirror 2 during assembly, thus avoiding the risk of the rearview mirror 2 breaking at the edge.

[0037] In addition, the elasticity of the elastic edge member 12 allows the rearview mirror 2 to be positioned by slight compression during installation, reducing the reliance on high-precision robots for positioning and lowering production line costs.

[0038] Optionally, refer to Figure 2 As shown, the elastic edge member 12 includes a base 121 and a protrusion 122; the base 121 is connected to the edge of the mirror holder body 11 in the first direction A, and the protrusion 122 is connected to the base 121 and extends along the second direction B; the rearview mirror 2 abuts against the protrusion 122 along the edge of the first direction A in the first direction A; wherein, the second direction B is the thickness direction of the rearview mirror 2.

[0039] In this embodiment, the protrusion 122 extends along the second direction B, that is, along the thickness direction of the rearview mirror 2, forming a wrapping effect on the edge of the rearview mirror 2, ensuring the stable fixation of the rearview mirror 2 in the thickness direction and preventing displacement due to vibration or impact. The base 121 serves as an elastic deformation fulcrum, concentrating the deformation of the protrusion 122 in a preset direction, preventing the overall failure of the elastic edge member 12. In addition, by adjusting the extension length of the protrusion 122 in the second direction B, it can be adapted to rearview mirrors 2 of different thicknesses.

[0040] In another embodiment, refer to Figure 2 As shown, the mirror holder body 11 has a groove 110 recessed along the edge of the first direction A, and the base 121 is disposed in the groove 110.

[0041] In this embodiment, by providing the groove 110, the base 121 can be embedded into the mirror holder body 11, enhancing the connection strength between the elastic edge member 12 and the mirror holder body 11, and preventing the elastic edge member 12 from falling off during long-term use. The groove 110 can hide the seam between the elastic edge member 12 and the mirror holder body 11, ensuring that there are no protrusions or gaps on the exposed surface, thus improving smoothness.

[0042] In one implementation, reference Figure 2 As shown, the protrusion 122 includes a first side surface 1220 that is away from the rearview mirror 2 along the first direction A, and the base 121 includes a second side surface 1210 that is away from the mirror holder body 11 along the first direction A. The mirror holder body 11 has an edge surface 111 formed at the edge of the first direction A. The first side surface 1220 and the second side surface 1210 are smoothly connected, and the second side surface 1210 is smoothly connected to the edge surface 111.

[0043] In this embodiment, the design of a smooth transition connection surface avoids the problem of local stress concentration, significantly reduces the risk of material fatigue fracture, and extends service life. In low-temperature winter environments, the mirror holder 1 and rearview mirror 2 may experience dimensional changes due to thermal shrinkage, which can be absorbed by the uniform deformation of the elastic edge member 12, further dispersing shrinkage stress by smoothing the connection surface.

[0044] Furthermore, the smooth transition design meets the requirements of motor vehicle rearview mirror regulations, avoiding safety risks caused by sharp edges.

[0045] In addition, the design of the smooth connection between the first side 1220 and the second side 1210, and the smooth connection between the second side 1210 and the edge surface 111, can effectively reduce wind resistance and turbulence noise during vehicle operation and improve the overall NVH (Noise, Vibration, Harshness) performance of the vehicle.

[0046] In another way, refer to Figure 2 As shown, the base 121 includes a third side 1211 along the second direction B near the rearview mirror 2, and the mirror holder body 11 includes a fourth side 112 along the second direction B near the rearview mirror 2. The third side 1211 and the fourth side 112 are smoothly connected.

[0047] In this embodiment, the smooth connection between the third side 1211 and the fourth side 112 forms a continuous closed interface, effectively preventing rainwater, dust, etc. from intruding from the back of the rearview mirror 2 into the interior of the mirror holder 1.

[0048] Secondly, under the impact of high-pressure water guns during car washing or the wind pressure of high-speed driving, the smooth connection surface reduces the fluid penetration path, effectively improving waterproof and dustproof performance.

[0049] When the rearview mirror 2 is subjected to external impact, the continuous interface between the third side 1211 and the fourth side 112 allows the impact force to be evenly diffused from the elastic edge member 12 to the rigid mirror support body 11, avoiding stress concentration at a single connection point and preventing interface cracking.

[0050] In addition, in a vehicle vibration environment, a smooth connection surface can reduce wear between the elastic edge piece 12 and the mirror holder body 11 caused by high-frequency friction, thus extending their service life.

[0051] Furthermore, in conjunction with the two-color injection molding process, that is, the elastic edge piece 12 and the lens holder body 11 are formed by the two-color injection molding process. The smooth interface design between the rigid lens holder body 11 and the elastic edge piece 12 improves the material flow path and ensures that the elastic material (such as TPU) is fully filled into the groove 110 of the lens holder body 11, avoiding insufficient filling or bubble defects caused by sharp corners.

[0052] Optionally, the length of the protrusion 122 extending along the second direction B is not less than the thickness of the rearview mirror 2, ensuring that the protrusion 122 can effectively wrap around the edge of the rearview mirror 2, providing a larger support area and a more stable structural connection, and reducing the shaking of the rearview mirror when subjected to external forces.

[0053] Secondly, during vehicle operation, the rearview mirror 2 may be affected by external forces such as wind and collisions. The longer extension 122 can better disperse and absorb these external forces, thereby reducing the risk of damage to the rearview mirror.

[0054] Optionally, the thickness of the protrusion 122 in the first direction A is not less than 0.33 mm. For example, the thickness of the protrusion 122 in the first direction A can be 0.4 mm, which is almost negligible in size compared with the entire rearview mirror 2, thereby increasing the mirror ratio of the rearview mirror 2 and giving the rearview mirror structure of this disclosure an almost frameless visual feel, thus improving aesthetics.

[0055] Optionally, the Shore hardness of at least the protruding portion 122 of the resilient edge member 12 is not greater than 60HA. A lower Shore hardness means that the resilient edge member 12 has better flexibility and cushioning performance, and can effectively absorb energy when subjected to external impact, reducing the impact on the rearview mirror 2.

[0056] Secondly, during vehicle operation, the rearview mirror 2 may generate noise due to vibration. The low hardness design of the elastic edge member 12 can reduce the transmission of this vibration, thereby reducing noise.

[0057] In addition, in the event of a collision or scratch, the low-hardness elastic edge component can reduce damage to surrounding objects (such as pedestrians, vehicles, etc.) and improve safety.

[0058] For example, the elastic edge member 12 may have only the Shore hardness of the protrusion 122 not greater than 60HA, or the Shore hardness of the entire elastic edge member 12 may not be greater than 60HA. This disclosure does not limit this.

[0059] Furthermore, the specific material of the elastic edge member 12 can be silicone rubber, nitrile rubber, or thermoplastic rubber, etc. This disclosure does not limit the specific material of the elastic edge member 12.

[0060] Optionally, the base 121 and the protrusion 122 are constructed as a single integral structure. This integral molding eliminates the need for separate assembly steps, reducing production costs. Furthermore, it eliminates the risk of interface separation that may occur with separate structures, enhancing the overall durability of the elastic edge member 12.

[0061] Optionally, the lens holder body 11 and the elastic edge member 12 are formed using a two-color injection molding process. For example, the lens holder body 11 can be made of a rigid material (such as ABS) to ensure rigidity, and the elastic edge member 12 can be made of a soft rubber (such as TPU) to achieve elasticity. However, this disclosure does not limit the specific molding method of the lens holder body 11 and the elastic edge member 12.

[0062] Reference Figure 1 As shown, the rearview mirror structure also includes an adhesive layer 3, through which the rearview mirror is bonded to the mirror holder body 11.

[0063] The adhesive layer 3 works in conjunction with the elastic edge member 12 to both secure the rearview mirror 2 to the back and limit its edge movement, reducing the risk of the rearview mirror 2 falling off. Regarding the specific material selection for the adhesive layer 3, double-sided tape or a heating element can be used, but this disclosure does not limit the specific material of the adhesive layer 3.

[0064] This disclosure also provides a vehicle that includes the aforementioned rearview mirror structure.
