Description

Technical Field

[0001] The present application relates to the technical field of vehicle rearview mirrors, and more particularly to a rearview mirror assembly and a vehicle. Background Art

[0002] In the related art, users have increasingly higher requirements for the sensory quality of automobiles and the reduction of wind noise. As an important component of the side safety parts, the shaping effect, function definition, and sensory quality of the exterior rearview mirror are also becoming more and more important.

[0003] The lens assembly of the exterior rearview mirror is rotatably connected to the base. To ensure the smooth rotation of the lens assembly relative to the base, a gap is usually provided at the connection between the lens assembly and the base. However, when the air flow quickly passes through this gap, wind noise will be generated. In this regard, a windproof pad can be provided to block the gap to avoid wind noise, but blocking the gap will affect the rotation of the lens assembly and generate abnormal noise during the folding of the rearview mirror. Therefore, the rearview mirror assembly in the prior art cannot avoid the abnormal noise during the folding of the rearview mirror while reducing the wind noise. Summary of the Invention

The windproof pad is movably disposed on the base and can move toward or away from the lens assembly, or the windproof pad is movably disposed on the lens assembly and can move toward or away from the base.

[0006] According to the rearview mirror assembly of the embodiment of the present application, a windproof pad is provided in the gap between the base and the lens assembly to reduce the wind noise, and the windproof pad is movably disposed on the lens assembly or the base, so that the windproof pad can move when being pressed, and the pressure is released through its own movement, thereby reducing the pressure in the contact area and further reducing the friction in the corresponding area. Thus, the windproof pad reduces the abnormal noise during the folding of the rearview mirror while achieving wind noise prevention, improving the user experience.

The second plate is configured with a guiding hole. The windproof pad extends a guiding block in the direction towards the second plate, and the guiding block passes through the guiding hole and fits against the hole wall of the guiding hole.

[0010] According to some embodiments of the present application, the connecting portion is configured as a connecting plate, and the pressure-receiving portion is configured as a pressure-receiving plate. The connecting plate is fixedly connected to the base. There is a movable space between one side of the pressure-receiving plate and the base, and the other side faces the lens assembly.

A first plate perpendicular to the windproof pad is formed on the top of the base, and the first plate extends to block the end of the pressure-receiving plate to enclose the movable space.

[0011] According to some embodiments of the present application, the first plate is bent to extend a second plate. The second plate is parallel to the windproof pad. The second plate faces the pressure-receiving plate and there is a movable space therebetween. The second plate and the windproof pad participate in defining the top plate.

[0041] First, a rearview mirror assembly provided with a windproof pad 30a in the prior art will be described to facilitate the understanding of the subsequent embodiments.

[0042] Refer to Figure 3 As shown, the rearview mirror assembly includes a base 10a and a lens assembly 20a, and a gap is defined between the lens assembly 20a and the base 10a. A top plate 21a is formed on one side of the base 10a facing the lens assembly 20a. A windproof pad 30a is provided between the lens assembly 20a and the base 10a to block the gap between the lens assembly 20a and the base 10a. Moreover, the windproof pad 30a is constructed of an elastic material capable of expansion and contraction, the top plate 21a is constructed of a rigid material, and an injection molding groove 22a is formed on the top plate 21a to be adapted to fix the windproof pad 30a on the top plate 21a.

[0043] Next, refer to Figure 1 to describe the rearview mirror assembly and the vehicle according to the embodiments of the present application.

[0044] The rearview mirror assembly according to the embodiments of the present application includes a base 10, a lens assembly 20, and a windproof pad 30.

[0045] Refer toFigure 1 As shown, the base 10 is used to connect to the vehicle body, such as being fixed to the door sheet metal; the lens assembly 20 is connected to the base 10 to provide an image of the rear of the vehicle body to the cockpit. Moreover, the lens assembly 20 is movably arranged on the base 10, so that the position of the lens assembly 20 can be adjusted as needed, and the rearview mirror assembly can be folded and stored, so as to reduce the probability of scratching after parking and improve the passing performance of the vehicle under special road conditions, that is, the lens assembly 20 is rotatably arranged on the base 10, so as to realize the folding function through a rotating action.

[0046] For example Figure 1 As shown, a connecting shaft 11 is arranged on the base 10, and the lens assembly 20 is formed with a shaft hole 21. After the connecting shaft 11 and the shaft hole 21 are rotationally matched, the lens assembly 20 can rotate relative to the base 10, so as to realize the folding function of the rearview mirror. When the user needs to park the vehicle, the lens assembly 20 can be rotated around the connecting shaft 11 manually or by electric drive until it is folded to a position close to the vehicle body, so as to reduce the occupied space and avoid damage. On the contrary, when driving and needing to use the rearview mirror assembly, the user can also unfold the lens assembly 20 to a normal use angle through corresponding operations.

[0047] When the lens assembly 20 rotates relative to the base 10, the lens assembly 20 may move axially along the axis of the connecting shaft 11; or shake and tilt during the rotation process, resulting in part of the lens assembly 20 approaching the base 10 during rotation. In order to ensure that the lens assembly 20 can rotate smoothly, a gap b is left at the mating part of the base 10 and the lens assembly 20, and the gap b is substantially perpendicular to the connecting shaft 11; in this way, the gap b can provide a certain margin for the lens assembly 20, so as to allow the lens assembly 20 to shake and move axially within a certain range, ensuring the smooth rotation of the lens assembly 20.

[0048] Moreover, when the air flow generated during the operation of the vehicle passes through the rearview mirror assembly, the air will form a turbulent flow at the gap b between the base 10 and the lens assembly 20, and this turbulent flow will cause a rapid change in air pressure, thereby generating wind noise.

[0049] Therefore, as Figure 1 shown, a windproof pad 30 is arranged between the base 10 and the lens assembly 20 and is adapted to block the gap b between the base 10 and the lens assembly 20. In this way, by blocking the gap b between the base 10 and the lens assembly 20, the windproof pad 30 can reduce or eliminate the turbulent flow generated when the air flow passes through the gap b, so that the air flow can flow through the rearview mirror assembly more smoothly, thereby reducing the generation of eddy currents and the fluctuation of air pressure and effectively suppressing wind noise. In addition, the windproof pad 30 in some examples has certain sound absorption characteristics and can further absorb and weaken the generated noise.

[0050] However, as mentioned above, there is a gap b at the mating part of the base 10 and the lens assembly 20 to provide a margin for the rotational movement of the lens assembly 20 to maintain its smooth rotation; when the windproof pad 30 seals the gap b between the base 10 and the lens assembly 20, the margin between the lens assembly 20 and the base 10 will be reduced, resulting in the lens assembly 20 shaking and moving axially. When the lens assembly 20 shakes and moves axially, the lens assembly 20 will rub against the windproof pad 30, which will affect the rotation of the lens assembly 20 and generate frictional abnormal noise (i.e., abnormal noise during rearview mirror folding).

[0051] Therefore, the windproof pad 30 is movably arranged on the base 10, and the windproof pad 30 can move towards or away from the lens assembly 20; or the windproof pad 30 is movably arranged on the lens assembly 20, and the windproof pad 30 can move towards or away from the base 10. That is to say, when the lens assembly 20 rotates relative to the base 10 and generates extrusion and friction with the windproof pad 30, the lens assembly 20 or the base 10 will push the windproof pad 30 to move in the extrusion direction, that is, move substantially along the axis direction of the connecting shaft 11, so as to release the pressure it receives. In this way, the pressure on the windproof pad 30 from the lens assembly 20 or the base 10 can be partially released by its own movement, so that the windproof pad 30 can dynamically adjust its position when the lens assembly 20 rotates, thereby effectively reducing the pressure between the two, and then significantly reducing the friction force at the contact position to reduce the frictional abnormal noise.

[0052] Exemplarily, referring to Figure 1 , taking the case where the windproof pad 30 is movably arranged on the base 10 and the windproof pad 30 can move towards or away from the lens assembly 20 as an example for illustration.

[0053] The windproof pad 30 at least partially contacts the lens assembly 20. When the lens assembly 20 rotates, it may shake or move axially along the axis of the connecting shaft 11, resulting in some areas of the lens assembly 20 approaching the windproof pad 30. Correspondingly, the area of the windproof pad 30 in contact with the lens assembly 20 moves away from the lens assembly 20 after being pressured by the lens assembly 20; for example, in this example, the windproof pad 30 is made of a bendable material to release the pressure exerted by the lens assembly 20 on the windproof pad 30 through the movement of the windproof pad 30 bending away from the lens assembly 20.

[0054] It should be noted that in the existing rearview mirror assembly provided with the windproof pad 30a, the windproof pad 30a can be constructed of an elastic material that can expand and contract, so as to avoid the movement and shaking of the lens assembly 20a by its own expansion and contraction. However, since the top plate 21a and the windproof pad 30a are closely fitted and the top plate 21a is made of a rigid material, the resilience of the elastic windproof pad 30a will increase the pressure between the windproof pad 30a and the lens assembly 20a, resulting in an increase in the friction force and frictional noise between the corresponding areas of the windproof pad 30a and the lens assembly 20a. In contrast, in this embodiment, the windproof pad 30 can make the windproof pad 30 not exert too large a reaction force on the lens assembly 20 through a dynamic adjustment mechanism, and release the pressure through its own movement, effectively reducing the frictional noise between the lens assembly 20 and the base 10.

[0055] For the rearview mirror assembly according to the embodiment of the present application, while a windproof pad 30 is provided in the gap b between the base 10 and the lens assembly 20 to reduce wind noise, the windproof pad 30 is movably arranged on the lens assembly 20 or the base 10, so that the windproof pad 30 can move when pressed, so as to release the pressure by its own movement, thereby reducing the pressure in the contact area, and further reducing the friction force in the corresponding area, so that the folding noise of the rearview mirror is reduced. Thus, the windproof pad 30 reduces the folding noise of the rearview mirror while achieving wind noise prevention, improving the user experience.

[0056] Continue to describe the case where the windproof pad 30 is movably arranged on the base 10, and the windproof pad 30 can move towards or away from the lens assembly 20.

[0057] The windproof pad 30 includes a connecting portion 31 and a pressure receiving portion 32. The connecting portion 31 is fixedly connected to the base 10. One side of the pressure receiving portion 32 abuts against the lens assembly 20, and there is an activity space c between the other side and the base 10. After the pressure receiving portion 32 is pushed by the lens assembly 20, it bends into the activity space c to move towards the base 10.

[0058] Continue with Figure 1 as an example. A through hole 33 for passing through the connecting shaft 11 is provided in the center of the windproof pad 30. The area of the windproof pad 30 close to the connecting shaft 11 (i.e., close to the through hole 33) is constructed as the connecting portion 31, and the edge area of the windproof pad 30 is constructed as the pressure receiving portion 32. The pressure receiving portion 32 can bend relative to the connecting portion 31. In this way, when the lens assembly 20 moves or shakes, the part moving towards the base 10 will squeeze the pressure receiving portion 32 to cause bending, so that the pressure receiving portion 32 moves towards the activity space c and releases the pressure. Among them, at least the pressure receiving portion 32 of the windproof pad 30 is constructed of an elastic material, so as to bend or deform under the action of pressure and move towards the activity space c, thereby releasing the pressure. The elastic material can be any one of rubber materials, resin materials, etc.

[0059] It can be understood that one side of the pressure-receiving part 32 is used to bear the pressure of the lens assembly 20, and the other side can move to the moving space c, so that the pressure-receiving part 32 can adaptively adjust to different positions in the moving space c when being pressed, thereby releasing the pressure of the lens assembly 20 to different degrees, and further reducing the friction force and frictional abnormal noise in the corresponding area.

[0060] Furthermore, the lens assembly 20 is configured with a bottom plate 22, and the starting part of the shaft hole 21 is formed at the center of the bottom plate 22. The windproof pad 30 is configured as an integrally formed plate body and participates in defining the top plate 12 of the base 10. The bottom plate 22 and the top plate 12 are opposite to each other and define a gap b; as Figure 1 shown, the top plate 12 is the lower end surface of the lens assembly 20 for fitting to the base 10, and the bottom plate 22 is the upper end surface of the base 10 for fitting to the lens assembly 20. Among them, the integrally formed windproof pad 30 can be obtained by one-time injection molding using materials such as PTV material (thermoplastic vulcanized rubber), AS resin material, etc.

[0061] Compared with the conventional rearview mirror assembly, a separate plate body needs to be provided to form the bottom plate 22 of the lens assembly 20, and then the windproof pad 30 is provided on the bottom plate 22; in the embodiment of the present application, the integrally formed windproof pad 30 can be directly provided on the base 10 and participates in defining the bottom plate 22, without the need to additionally provide a fixing plate body, which simplifies the structure and reduces the process complexity while reducing the number of components.

[0062] For better illustration, reference can be made to Figure 3 the rearview mirror assembly in the prior art shown for understanding; Figure 3 In the rearview mirror assembly in, the top plate 21a is a rigid plate body, and an injection molding groove 22a is formed on the top plate 21a. During manufacturing, a soft windproof pad 30a needs to be disposed in the injection molding groove 22a formed on the rigid top plate 21a through processes such as secondary injection molding or two-color injection molding. Therefore, in the existing rearview mirror assembly, the top plate 21a and the windproof pad 30a are separately manufactured, and the top plate 21a and the windproof pad 30a need to be fixed on the top plate 21a through processes such as secondary injection molding or two-color injection molding.

[0063] In contrast, the windproof pad 30 in the embodiment of the present application is integrally formed with the top plate 12 of the base 10, reducing the number of components and simplifying the assembly process. Moreover, the windproof pad 30 and the top plate 12 of the base 10 are integrally formed, and can be completed by one-time injection molding process, which also reduces the manufacturing steps and simplifies the process.

[0064] Next, continue with the example of Figure 1 for illustration.

[0065] The top plate 12 further includes a second plate 121 located on the side of the windproof pad 30 away from the bottom plate 22. The second plate 121 is configured with a guiding hole 1211. The windproof pad 30 extends a guiding block 34 in the direction towards the second plate 121. The guiding block 34 passes through the guiding hole 1211, and the guiding block 34 is in contact with the hole wall of the guiding hole 1211.

[0066] Specifically, the guiding block 34 is configured in a shape matching the guiding hole 1211, which can be any geometric shape such as cylindrical, square, etc. The size of the guiding block 34 is slightly smaller than that of the guiding hole 1211 to ensure that it can move freely within the guiding hole 1211 and keep the guiding block 34 in contact with the hole wall of the guiding hole 1211 to maintain its guiding function.

[0067] When the lens assembly 20 rotates and approaches the windproof pad 30, the pressure-receiving part 32 of the windproof pad 30 will be pressured and start to bend. At this time, the guiding block 34 will slide along the inner wall of the guiding hole 1211, thereby guiding the bending direction of the windproof pad 30. Since the guiding block 34 is in contact with the hole wall of the guiding hole 1211, the bending movement of the windproof pad 30 will be restricted within the path defined by the guiding hole 1211, avoiding irregular deformation of the windproof pad 30 under pressure.

[0068] It can be understood that the guiding block 34 can effectively guide the bending movement of the windproof pad 30, ensuring that it can deform along a predetermined path when pressured, making the movement stability of the windproof pad 30 better during the pressure release process.

[0069] Furthermore, the connecting part 31 is configured as a connecting plate, and the pressure-receiving part 32 is configured as a pressure-receiving plate. The connecting plate and the pressure-receiving plate are integrally formed into a disc structure. A through hole 33 is configured at the center of the disc for passing through the connecting shaft 11. The part near the center area of the disc is the connecting plate, and the part in the edge area of the disc is the pressure-receiving plate. The connecting plate is fixedly connected to the base 10. There is a movable space c between one side of the pressure-receiving plate and the base 10, and the other side faces the lens assembly 20.

[0070] As Figure 1 shown, a spaced space is defined between the connecting plate and the bottom plate 22. A sealing protrusion 321 that abuts against the bottom plate 22 extends from the side of the pressure-receiving plate facing the lens assembly 20 to seal the spaced space; a first plate 13 perpendicular to the windproof pad 30 is formed on the top of the base 10. The first plate 13 extends to cover the end of the pressure-receiving plate to enclose the movable space c. Among them, the side of the sealing protrusion 321 facing the lens assembly 20 has an edge for contacting the bottom plate 22 to form a seal. The first plate 13 is formed beside the edge of the pressure-receiving plate and fits with the end of the pressure-receiving plate to seal the movable space c inside.

[0071] It can be understood that the sealing protrusion 321 seals the space between the top plate 12 and the gasket, and the first plate 13 extends beside the pressure receiving plate to seal the moving space c. In this way, the sealing protrusion 321 and the first plate 13 can seal the gap b between the lens assembly 20 and the base 10, thereby suppressing wind noise.

[0072] Furthermore, the first plate 13 is bent to extend a second plate 121. The second plate 121 is parallel to the windproof pad 30. The second plate 121 faces the pressure receiving plate and there is a moving space c therebetween. The second plate 121 and the windproof pad 30 participate in defining the top plate 12. In other words, the second plate 121 is located below the pressure receiving plate.

[0073] Therefore, when the lens assembly 20 shakes or moves axially along the connecting shaft 11 during rotation, the pressure receiving plate will be subjected to the pressure from the lens assembly 20 and bend towards the base 10. Since there is a moving space c between the pressure receiving plate and the second plate 121, when the pressure receiving plate moves towards the moving space c to the limit position under the action of the pressure, it will move down to fit the second plate 121, thereby restricting the excessive movement or shaking of the lens assembly 20. In this way, the second plate 121, as the lower limit support structure of the pressure receiving plate, can effectively prevent the pressure receiving plate from being excessively bent or deformed under the action of the pressure, and further avoid unstable shaking or movement of the lens assembly 20 during rotation.

[0074] It can be understood that the moving space c between the second plate 121 and the pressure receiving plate provides sufficient movement margin for the pressure receiving plate, enabling the pressure receiving plate to flexibly adjust its position when the lens assembly 20 applies pressure. At the same time, through the support of the second plate 121, it is ensured that the movement range of the pressure receiving plate is limited within a reasonable range to ensure that the bending action of the pressure receiving plate is more stable and controllable. This enables the windproof pad 30 to effectively release the pressure applied by the lens assembly 20 while maintaining the stability of the rotation process of the lens assembly 20.

[0075] More specifically, the connecting portion 31 is configured with a plurality of fixing protrusions 35. The fixing protrusions 35 are evenly arranged on the connecting portion 31 and are used for fixedly connecting with the base 10.

[0076] In Figure 1 In the corresponding example, the fixing protrusions 35 are configured as a ring structure and there are two of them. The first fixing protrusion 351 is formed at the edge of the through hole 33, and the second fixing protrusion 352 is configured in the transition region between the connecting portion 31 and the pressure receiving portion 32. Moreover, the thickness of the connecting plate is greater than the thickness of the pressure receiving plate, and the thickness difference forms a stepped surface at the connection between the connecting plate and the pressure receiving plate.

[0077] It can be understood that when the windproof pad 30 is integrally formed and the whole is made of an elastic material, a plurality of limiting protrusions formed on the connecting plate can firmly fix the connecting plate to the base 10, so as to provide a pulling and fixing effect on the connecting plate in each area to maintain the shape of the connecting plate. In this way, when the pressure-bearing plate is deformed under pressure, the connecting plate can maintain its shape under the action of the fixing protrusion 35, so as to support the pressure-bearing part 32 and enable the pressure-bearing part 32 to rebound under the support of the connecting part 31.

[0078] Based on the above example, in the thickness direction of the windproof pad 30, the height of the moving space c is defined as H2, and the height of the gap b is defined as H1.

[0079] Combined with Figure 1 - Figure 2 It is understood that when the lens assembly 20 has play or wobbles during rotation, it causes the bottom plate 22 and the top plate 12 to approach each other. At this time, the maximum distance that the windproof pad 30 is compressed and moves towards the moving space c is: the height H2 of the moving space c, that is, the windproof pad 30 can move at most to fit the second plate 121, so that the second plate 121 provides a supporting effect on the lens assembly 20 to keep the lens assembly 20 rotating stably.

[0080] Correspondingly, if the height H2 of the moving space c exceeds the height H1 of the gap b between the top plate 12 and the bottom plate 22, due to the excessive distance H2 between the second plate 121 and the windproof pad 30, when the lens assembly 20 moves down by a height of H1, the second plate 121 still cannot contact the windproof pad 30, resulting in friction when the top plate 12 and the base 10 are in contact. For example, if the lens assembly 20 is tilted relative to the base 10, and the lens assembly 20 has been tilted and moves towards the base 10 by a distance of H1, the windproof pad 30 responds and also moves down by a distance of H1, but cannot be supported by the second plate 121, then the phenomenon of contact and friction occurs between the edge of the top plate 12 and the edge of the bottom plate 22.

[0081] Therefore, the height H2 of the moving space c should be less than the height H1 of the gap b to ensure that the second plate 121 can play a role in supporting and stabilizing when the lens assembly 20 has play or wobbles during rotation.

[0082] The inventor further considered that in a low-temperature environment, the windproof pad 30 may freeze, resulting in difficulty in bending the pressure-bearing part 32, or the rubber and other materials harden due to temperature reduction, making it difficult for the windproof pad 30 to bend and release pressure.

[0083] In some embodiments, the windproof pad 30 is further connected with a heating element 40, and the heating element 40 is used to heat the windproof pad 30. As Figure 1As shown, the heating element 40 can be configured as an electric heating sheet that is fitted on the pressure-receiving plate. The electric heating sheet can be connected to the rearview mirror temperature sensor. When the winter temperature drops below zero degrees Celsius, it triggers the lower temperature limit set by the temperature sensor and automatically activates the electric heating sheet. The electric heating sheet heats the windproof pad 30, thereby eliminating ice accumulation and preventing the windproof pad 30 from hardening, so as to ensure that the windproof pad 30 can be bent smoothly.
