[0030] In order to enable those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] The embodiments of the present application provide a vehicle rearview mirror and a vehicle. Among them, the vehicle includes a vehicle body and a rearview mirror. The rearview mirror is arranged outside the vehicle body and is used to provide sufficient rear vision for the driver, improving the driving safety.

[0032] The vehicle rearview mirror includes a fixed part and a rotating part. The rotating part can rotate relative to the fixed part. Among them, the rotating part includes a first housing and a base 1, a motor, etc. arranged in the first housing. The motor is installed on the base 1, and the mirror is also installed on the first housing. The fixed part includes a bracket 2 and a second housing, etc. The bracket 2 is arranged in the second housing and is used to be fixed to the vehicle body. The second housing is used to provide protection for the bracket 2 and other components located in the second housing. The base 1 can rotate relative to the bracket 2 to a folded state and an unfolded state. In this embodiment, the unfolded state refers to the state of being unfolded to the maximum angle. Of course, the base 1 can rotate relative to the bracket 2 to any position between the folded state and the unfolded state.

[0033] The base 1 is provided with a first blocking structure 11 and a second blocking structure 12, and the bracket 2 is provided with a third blocking structure 21 and a fourth blocking structure 22. When the base 1 rotates relative to the bracket 2 to the folded state, as Figure 1 and Figure 2As shown, the first blocking structure 11 and the third blocking structure 21 are in abutting limit to restrict the base 1 from further rotating in the folding direction. Moreover, a buffer member 3 is provided between the first blocking structure 11 and the third blocking structure 21. The provision of this buffer member 3 can avoid the hard impact between the first blocking structure 11 and the third blocking structure 21. While providing protection for both of them, it can also reduce the noise generated by the impact and improve the user experience. Similarly, when the base 1 rotates relative to the bracket 2 to the unfolded state, the second blocking structure 12 and the fourth blocking structure 22 are in abutting limit to restrict the base 1 from further rotating in the unfolding direction. Moreover, a buffer member 3 is also provided between the second blocking structure 12 and the fourth blocking structure 22. The provision of this buffer member 3 can avoid the hard impact between the second blocking structure 12 and the fourth blocking structure 22. While providing protection for both of them, it can also reduce the noise generated by the impact and improve the user experience.

[0034] As Figure 4 shown, the base 1 is provided with a first stopper 14, and both the above-mentioned first blocking structure 11 and the second blocking structure 12 are formed by the wall surface of the first stopper 14. As Figure 5 shown, the bracket 2 is provided with a second stopper 23, and both the above-mentioned third blocking structure 21 and the fourth blocking structure 22 are formed by the wall surface of the second stopper 23.

[0035] Specifically, it can be as Figures 1 - 5 shown that there are two first stoppers 14 and one second stopper 23. When the base 1 rotates relative to the bracket 2, the second stopper 23 can rotate between the two first stoppers 14. At this time, the side wall surfaces of the two first stoppers 14 facing the second stopper 23 respectively form the above-mentioned first blocking structure 11 and the second blocking structure 12, the side wall surface of the second stopper 23 forms the third blocking structure 21, and the other side wall surface of the second stopper 23 forms the fourth blocking structure 22; or, there can also be one first stopper 14 and two second stoppers 23, and the first stopper 14 can rotate between the two first stoppers 14. At this time, one side wall surface of the first stopper 14 forms the first blocking structure 11, the other side wall surface of the first stopper 14 forms the second blocking structure 12, and the side wall surfaces of the two second stoppers 23 facing the first stopper 14 respectively form the above-mentioned third blocking structure 21 and the fourth blocking structure 22, and only two buffer members 3 are provided.

[0036] Of course, in this embodiment, there is no limitation on the specific structure of each blocking structure. For example, the base 1 may be provided with a limiting groove, and the bracket 2 may be provided with a limiting protrusion. The two side walls of the limiting groove respectively form the above-mentioned first blocking structure 11 and second blocking structure 12. During the rotation of the base 1 relative to the bracket 2, the limiting protrusion can slide relatively in the limiting groove, and the two end faces of the limiting protrusion respectively form the third blocking structure 21 and the fourth blocking structure 22. Alternatively, the bracket 2 may be provided with a limiting groove, and the base 1 may be provided with a limiting protrusion. When the above-mentioned blocking structures are formed by the wall surfaces of the first stopper 14 and the second stopper 23, the overall structure and the molding process can be simplified.

[0037] The rearview mirror further includes a seal 4, which is sealingly disposed between the fixed part and the rotating part for achieving sealing between the fixed part and the rotating part, specifically for achieving sealing between the first housing and the second housing, so as to prevent air flow from entering the interior along the gap between the fixed part and the rotating part during the driving of the vehicle, thereby generating noise, and thus achieving the effect of noise reduction and improving the NVH (Noise, Vibration, Harshness) performance of the vehicle.

[0038] In this embodiment, the buffer member 3 is fixedly provided on the seal. Of course, one of the first blocking structure 11 and the third blocking structure 21 may be provided with the buffer member 3, and at the same time, one of the second blocking structure 12 and the fourth blocking structure 22 may be provided with the above-mentioned buffer member 3. When the buffer member 3 is fixedly provided on the seal 4, there is no need to modify the structures of the base 1 and the bracket 2. Only the structure of the seal 4 needs to be improved to make it have the buffer member 3 to implement the above solution, thereby being able to simplify the overall structure, reduce costs, and be adapted to the structures of the fixed part and the rotating part in the prior art, with good flexibility and a wide range of applications.

[0039] A connecting shaft portion is further provided between the fixed part and the rotating part, and the two can rotate relative to each other along the connecting shaft portion. In this embodiment, there is no limitation on the specific structure of the connecting shaft portion, such as Figure 6 As shown, the seal 4 is provided with an inner hole 44, and the connecting shaft portion can pass through the inner hole 44, and the seal 4 can seal the first housing and the second housing along the circumferential direction of the connecting shaft portion.

[0040] Such as Figure 6 As shown, an extension portion 45 is provided on the inner edge of the inner hole 44 protruding radially inward, and the buffer member 3 is fixedly provided on the surface of the extension portion 45. In this way, it is convenient to realize the cooperation and abutment of the buffer member 3 with the blocking structure, and to avoid the situation that the setting of the buffer member 3 interferes with the installation of other components.

[0041] Specifically, the buffer member 3 is disposed on one surface of the extension portion 45, and the specific setting direction can be determined according to the actual situation. For example, in the installed state, both the first blocking structure 11 and the second blocking structure 12 are located within the first housing, and the third blocking structure 21 and the fourth blocking structure 22 of the bracket 2 can extend into the first housing. At this time, the buffer member 3 is disposed on the surface of the extension portion 45 facing the rotating portion. Alternatively, it can also be that both the third blocking structure 21 and the fourth blocking structure 22 are located within the second housing, and both the first blocking structure 11 and the second blocking structure 12 of the base portion 1 can extend into the second housing. At this time, the buffer member 3 is disposed on the surface of the extension portion 45 facing the fixed portion.

[0042] As Figure 6 As shown, a protruding portion 31 is provided on the surface of the extension portion 45. Elastic pads 33 are respectively provided on both side wall surfaces of the protruding portion 31 along the circumferential direction of the inner hole 44, and the elastic pads 33 can form the above-mentioned buffer member 3. Among them, there is no limitation on the specific material of the protruding portion 31. For example, the protruding portion 31 can be made of plastic material. The protruding portion 31 can provide support for the elastic pads 33, ensuring that the buffer member 3 can stably adhere to the first blocking structure 11 and the second blocking structure 12, and can also ensure the structural strength of the buffer member 3, avoiding deformation or damage after multiple collisions, and ensuring the service life of the buffer member 3.

[0043] As Figure 6 and Figure 7 As shown, first engaging portions are respectively provided on both side wall surfaces of the protruding portion 31 along the circumferential direction of the inner hole 44, and the elastic pads 33 are provided with second engaging portions. The protruding portion 31 and the elastic pads 33 are also engaged through the first engaging portions and the second engaging portions to ensure structural stability. A second reinforcing rib 5 is also provided between the protruding portion 31 and the seal 4 to further ensure structural stability.

[0044] Specifically, it can be as Figure 7 shown. The first engaging portion is the convex rib 32 provided on the protruding portion 31, and the second engaging portion is the engaging groove 34 provided on the elastic pad 33. It can also be that the first engaging portion is the engaging groove 34 provided on the protruding portion 31, and the second engaging portion is the convex rib 32 provided on the elastic pad. The shapes and structures of the convex rib 32 and the engaging groove 34 are adapted to each other.

[0045] Taking the first engaging portion as the convex rib 32 provided on the protruding portion 31 and the second engaging portion as the engaging groove 34 provided on the elastic pad 33 as an example, the width of the opening of the engaging groove 34 is smaller than the width of the bottom of the groove. In this way, the width of one side of the convex rib 32 facing the protruding portion 31 is smaller than the width of the side facing the elastic pad 33. The cross-section of the convex rib 32 can be as Figure 7The structure shown is trapezoidal, or it can also be T-shaped. The provision of the convex rib 32 and the mating groove can increase the contact area between the protruding portion 31 and the elastic pad 33, enhancing the joint action between the two. At the same time, since the width of the side of the convex rib 32 facing the protruding portion 31 is smaller than the width of the side facing the elastic pad 33, it can prevent the elastic pad 33 wrapped around the convex rib 32 from detaching from the convex rib 32, thereby ensuring the connection stability between the elastic pad 33 and the protruding portion 31.

[0046] As Figure 7 shown, the surface of the elastic pad 33 away from the convex rib 32 is a planar structure, which is convenient for fitting with the above-mentioned various blocking structures, ensuring stable abutting action and extending the service life.

[0047] In this embodiment, the buffer member 3 and the seal member 4 can be integrally formed structures, so that during the preparation of the seal member 4, the required buffer member 3 is formed simultaneously. In this way, it is possible to simplify the overall structure and the molding process, achieve a noise reduction effect during the folding and unfolding of the rearview mirror, and at the same time reduce costs.

[0048] When the buffer member 3 includes the protruding portion 31 and the elastic pad 33, the buffer member 3 and the seal member 4 are integrally formed by two-color injection molding. Specifically, the two-color injection molding technology is a well-known existing technology in the art and will not be elaborated here to save space.

[0049] Of course, in this embodiment, the buffer member 3 can also be fixed to the seal member 4 by bonding, snap-fitting, etc., or the elastic pad 33 and the protruding portion 31 can be fixed by bonding, sleeving, etc. When the buffer member 3 and the seal member 4 are integrally formed by two-color injection molding, it is possible to simplify the molding process and effectively reduce costs, and at the same time ensure the connection stability between the buffer member 3 and the seal member 4.

[0050] As Figure 6 shown, the seal member 4 includes a support layer 42 and a seal layer 43 that are fixedly connected to each other. Among them, the support layer 42 is used to be fixed to one of the bracket 2 or the base 1, and the seal layer 43 is fixedly provided on the support layer 42 to be in sealing contact with the other of the bracket 2 or the base 1. The above-mentioned extension portion 45 is provided on the support layer 42. The support layer 42 is used to achieve the fixing function and provide support for the seal layer 43 to prevent the seal layer 43 from deforming or wrinkling during the rotation of the rotating portion relative to the fixed portion. The support layer 42 can be made of a plastic layer, and the seal layer 43 can be made of a flexible material such as rubber to ensure sealing performance.

[0051] Of course, in this embodiment, it can also be that the support layer 42 is wrapped with the seal layer 43, that is, the seal layer 43 is provided on both side surfaces of the support layer 42, and it can be specifically set according to the actual situation. And for the buffer member 3, it can be asFigure 7 Only the two side walls of the protruding portion 31 along the circumferential direction of the inner hole 44 are wrapped with elastic pads 33. There are no restrictions on the other walls of the protruding portion 31. It can be provided with elastic pads 33 or not provided with elastic pads 33.

[0052] The seal 4 can be fixed to the base 1 or fixed to the bracket 2. There are no restrictions on the specific fixing method. Specifically, it can be fixed by snap connection or by bonding, etc. And snap connection can simplify the disassembly and assembly operation.

[0053] Taking the seal 4 fixed to the base 1 as an example, the seal 4 (specifically the support layer 42) is provided with a first snap member 41 (as Figure 6 shown), and the base 1 is provided with a second snap member 13 (as Figure 4 shown). The seal 4 and the base 1 can be snap-fixed through the first snap member 41 and the second snap member 13. Specifically, the first snap member 41 is a plurality of claws 411 provided on the seal 4, and a snap protrusion 412 is provided on the side wall of each claw 411. The second snap member 13 is a plurality of snap holes or slots provided on the base 1. The snap holes or slots are provided on the mounting surface of the base 1 for mounting the seal 4. During installation, each claw 411 is respectively aligned with the corresponding snap hole or slot, and then the seal 4 is pressed, so that the claws 411 are inserted into the snap holes or slots, and the snap protrusion 412 is engaged with the end face of the snap hole or the pit provided in the slot, etc., to fix the seal 4 to the mounting surface of the base 1.

[0054] To ensure the snap connection stability, as Figure 6 shown, a first reinforcing rib 413 is also provided between the claw 411 and the seal 4.

[0055] In this embodiment, it can also be that the first snap member 41 is a snap hole or slot provided on the seal 4, and the second snap member 13 is a claw 411 provided on the base 1. There are no specific restrictions here.

[0056] As Figure 2 shown, in the fixed state, the first blocking structure 11 and the second blocking structure 12 are respectively provided with buffer members 3 in a fitting manner. When the base 1 rotates relative to the bracket 2 to the folded state, the third blocking structure 21 abuts and fits against the buffer member 3 of the first blocking structure 11 to achieve blocking and limiting. When the base 1 rotates relative to the bracket 2 to the unfolded state, the fourth blocking structure 22 abuts and fits against the buffer member 3 of the second blocking structure 12 to achieve blocking and limiting.
