[0036] The following refers to Figures 1 - 8 Describe the vehicle rearview mirror 100 according to an embodiment of the present utility model.

[0037] As Figure 1 , Figure 2 and Figure 3 shown, the vehicle rearview mirror 100 according to an embodiment of the present utility model includes a mirror leg 1, a lens 2, and a limiting structure 3.

[0038] Specifically, as Figure 1 shown, in combination with Figure 2 and Figure 3 , the lens 2 is rotatably provided on the mirror leg 1. The mirror leg 1 can be used to connect to the vehicle body, and the connection between the lens 2 and the vehicle body can be realized. The mirror leg 1 is fixedly arranged relative to the vehicle body, and the lens 2 can rotate around the rotation axis of the lens 2 and the mirror leg 1 to realize the unfolding and folding functions of the vehicle rearview mirror 100.

[0039] Further, the limiting structure 3 includes a limiting chute 31 and a support block 32. One of the limiting chute 31 and the support block 32 is provided on the temple 1, and the other is provided on the lens 2. The limiting chute 31 is an arc extending in the circumferential direction along the rotation axis of the lens 2 and the temple 1, and the support block 32 is slidably arranged in the limiting chute 31.

[0040] It can be understood that the support block 32 can slide in the arc-shaped limiting chute 31, and the limiting chute 31 extends in the circumferential direction along the rotation axis of the lens 2 and the temple 1. Thus, the support block 32 can perform circumferential movement around the rotation axis of the lens 2 and the temple 1, that is, the limiting chute 31 and the support block 32 can rotate relative to each other around the rotation axis of the lens 2 and the temple 1, so as to allow relative rotation between the lens 2 and the temple 1 to realize the unfolding and folding of the vehicle rearview mirror 100. At the same time, when the lens 2 rotates around the rotation axis of the lens 2 and the temple 1 towards the front or the rear of the vehicle, the two end faces in the length direction of the limiting chute 31 can abut against the support block 32 to realize the limitation of the rotation stroke of the lens 2. That is, the limiting structure 3 can be used to provide a limiting function, which can prevent the lens 2 from rotating excessively relative to the temple 1, resulting in the lens 2 colliding with the vehicle body or damaging the vehicle rearview mirror 100.

[0041] Specifically, the two end faces in the length direction of the limiting chute 31 can be respectively denoted as a first end face 312 and a second end face 313. When the vehicle is driving normally, the vehicle rearview mirror 100 is in an unfolded state, and at this time, the support block 32 is arranged at an interval from the first end face 312 and the second end face 313. When an external force such as manual or electric force acts on the lens 2, the lens 2 rotates, and relative movement occurs between the limiting chute 31 and the support block 32 in the circumferential direction of the rotation axis of the lens 2 and the temple 1.

[0042] Assume that the limiting chute 31 is provided on the temple 1 and is stationary relative to the vehicle body, and the support block 32 is provided on the lens 2. If an external force acts on the lens 2 towards the rear of the vehicle, the support block 32 slides towards the direction close to the second end face 313 of the limiting chute 31, and the limiting function of the limiting structure 3 is realized through the abutment between the second end face 313 and the support block 32, so as to realize the limitation of the rotation stroke of the lens 2 and prevent the lens 2 from rotating excessively relative to the temple 1 towards the rear of the vehicle, resulting in damage to the lens 2 when it collides with the vehicle body; if an external force acts on the lens 2 towards the front of the vehicle, the support block 32 slides towards the direction close to the first end face 312 of the limiting chute 31, and the limiting function of the limiting structure 3 is realized through the abutment between the first end face 312 and the support block 32, thereby realizing the limitation of the rotation stroke of the lens 2 and preventing the lens 2 from rotating excessively relative to the temple 1 towards the front of the vehicle, resulting in the lens 2 colliding with the vehicle body or damaging the vehicle rearview mirror 100.

[0043] In a specific embodiment, such as Figure 2 and Figure 3 shown in the example, the support stop 32 is provided on the temple 1, and the limiting sliding groove 31 is provided on the lens 2. When an external force such as manual or electric force acts on the lens 2, the lens 2 rotates. The support stop 32 remains stationary relative to the vehicle body with respect to the temple 1, and the arc-shaped limiting sliding groove 31 makes a circumferential movement around the rotation axis of the lens 2 and the temple 1. As Figure 5 shown in the example, when an external force acting on the lens 2 is directed towards the rear of the vehicle, the first end face 312 of the limiting sliding groove 31 moves towards the direction close to the support stop 32. When the vehicle rearview mirror 100 is in the folded state, the first end face 312 of the limiting sliding groove 31 can abut against the support stop 32, and the support stop 32 can limit the continuous circumferential movement of the limiting sliding groove 31. As Figure 4 shown in the example, when an external force acting on the lens 2 is directed towards the front of the vehicle, the second end face 313 of the limiting sliding groove 31 moves towards the direction close to the support stop 32, and the second end face 313 of the limiting sliding groove 31 can abut against the support stop 32. Thus, the support stop 32 can limit the continuous circumferential movement of the limiting sliding groove 31.

[0044] It should be noted that the support stop 32 can also be connected to the lens 2, and the limiting sliding groove 31 is provided on the temple 1. The present application does not make specific limitations on this.

[0045] Wherein, at least one of the two end faces in the length direction of the limiting sliding groove 31 is provided with a first mating structure 311, and at least one of the two opposite end faces of the support stop 32 is provided with a second mating structure 321 that mates with the first mating structure 311. One of the first mating structure 311 and the second mating structure 321 is a protrusion, and the other is a groove.

[0046] It can be understood that when the lens 2 rotates under the action of an external force, the two end faces in the length direction of the limiting sliding groove 31 can abut against the support stop 32 to realize the limitation of the lens 2 in the circumferential direction of the rotation axis of the lens 2 and the temple 1. At this time, the first mating structure 311 cooperates with the second mating structure 321, and the protrusion can be inserted into the groove, and the side wall of the protrusion can be attached to the inner wall of the groove. Thus, a force in the radial direction of the rotation axis of the lens 2 will be generated between the limiting sliding groove 31 and the support stop 32, so as to realize the limitation of the lens 2 in the radial direction of its rotation axis, which can better solve the problem that the lens 2 is prone to sliding and instability during limitation, prevent the lens 2 from colliding with the vehicle body due to slight movement in the radial direction of its rotation axis and causing scratches, and can enhance the limiting effect of the limiting structure 3, and further improve the reliability and stability of the vehicle rearview mirror 100.

[0047] Among them, the cooperation between the first cooperation structure 311 and the second cooperation structure 321 is realized by a cooperation structure in which a protrusion is inserted into a groove. The structure is simple and easy to process, which will not cause the production cycle to increase, and there is no need to additionally add other auxiliary components. For example, using double-block limiting, adding screw fixing and limiting, etc., will not increase the number of parts to be assembled, and can ensure low cost. On the other hand, the above structure will not be affected by the limitation of the layout space, nor will it increase the occupied volume of the limiting structure 3. At the same time, regardless of whether the rotation of the lens 2 is driven by manual external force or by electric drive, the above-mentioned limiting structure 3 can be applied, which has the advantage of high versatility.

[0048] In addition, under the cooperation of the first cooperation structure 311 of the limiting chute 31 and the second cooperation structure 321 of the support block 32, the side wall of the protrusion and the inner wall of the groove are mutually extruded, which can cause the limiting chute 31 and the support block 32 to simultaneously generate forces in the circumferential direction and the radial direction of the rotation axis of the lens 2 and the lens foot 1, which can better offset the external force applied to the lens 2, reduce the risk of structural damage such as the support block 32 breaking, thereby reducing the probability of the limiting structure 3 failing, and further reducing the possibility of the lens 2 hitting the vehicle body, and can extend the service life of the vehicle rearview mirror 100.

[0049] It should be noted that the limiting chute 31 and the support block 32 can respectively be provided with a first cooperation structure 311 and a second cooperation structure 321 at one corresponding end, or the first cooperation structure 311 can be provided on both end faces opposite to each other in the length direction of the limiting chute 31, and the support block 32 is respectively provided with second cooperation structures 321 that cooperate with the two first cooperation structures 311 at both opposite end faces. In addition, the first cooperation structure 311 can be formed into a groove, and the second cooperation structure 321 can be formed into a protrusion. Of course, the first cooperation structure 311 can also be formed into a protrusion, and the second cooperation structure 321 can be formed into a groove.

[0050] It should be noted that when a driver is driving in a vehicle, he faces the front of the vehicle, and the rear of the vehicle is opposite to him.

[0051] According to the vehicle rearview mirror 100 of the embodiment of the present utility model, by rotatably arranging the lens 2 on the mirror leg 1, and making one of the limiting chute 31 and the support block 32 of the limiting structure 3 arranged on the mirror leg 1, and the other arranged on the lens 2, and the support block 32 is slidably arranged in the arc-shaped limiting chute 31, the unfolding and folding of the vehicle rearview mirror 100 can be realized, and the limiting function of the rotation of the lens 2 can be realized, preventing the lens 2 from rotating excessively relative to the mirror leg 1 so that the lens 2 collides with the vehicle body or causes damage to the vehicle rearview mirror 100. At the same time, by respectively arranging the mutually matching first matching structure 311 and the second matching structure 321 on the limiting chute 31 and the support block 32, and one of the first matching structure 311 and the second matching structure 321 is a protrusion and the other is a groove, the limiting effect can be enhanced, the limiting of the lens 2 in the radial direction of its rotation axis can be realized, and the problem that the lens 2 is prone to sliding instability during limiting can be better solved, preventing the lens 2 from rubbing against the vehicle body due to slight movement in the radial direction of the rotation axis, and further improving the reliability and stability of the vehicle rearview mirror 100. The risk of structural fracture and damage such as the support block 32 can also be reduced, and the service life of the vehicle rearview mirror 100 can be extended. And it has the advantages of simple structure, easy processing, low cost, small occupied space and high universality.

[0052] In some embodiments of the present utility model, as Figure 2 and Figure 3 shown, first matching structures 311 are arranged on both end faces in the length direction of the limiting chute 31, second matching structures 321 that cooperate with the two first matching structures 311 are respectively arranged on the opposite end faces of the support block 32, the first matching structure 311 is formed as a groove, and the second matching structure 321 is formed as a protrusion. Thus, no matter whether the lens 2 rotates around the rotation axis of the lens 2 and the mirror leg 1 towards the front of the vehicle or towards the rear of the vehicle, the limiting of the lens 2 in the rotation direction and the direction perpendicular to the rotation direction can be realized, the limiting effect of the limiting structure 3 can be enhanced, and the reliability and stability of the vehicle rearview mirror 100 can be further improved. At the same time, no matter whether the external force applied to the lens 2 is towards the front of the vehicle or the rear of the vehicle, the external force can be better offset, the risk of structural fracture and damage such as the support block 32 can be reduced, thereby reducing the probability of the failure of the limiting structure 3, and the service life of the vehicle rearview mirror 100 can be extended.

[0053] Among them, the two end faces in the length direction of the limiting chute 31 can be respectively denoted as the first end face 312 and the second end face 313, one end face of the support block 32 close to the first end face 312 is the third end face 322, and one end face of the support block 32 close to the second end face 313 is the fourth end face 323. As Figure 5In the illustrated example, when an external force is applied to the lens 2 towards the rear of the vehicle, the limit can be achieved through the abutment between the first end face 312 of the limit chute 31 and the third end face 322 of the support block 32. At this time, the second mating structure 321 formed as a protrusion on the third end face 322 is inserted into the first mating structure 311 formed as a groove on the first end face 312. As Figure 4 In the illustrated example, when an external force is applied to the lens 2 towards the front of the vehicle, the limit can be achieved through the abutment between the second end face 313 of the limit chute 31 and the fourth end face 323 of the support block 32. At this time, the second mating structure 321 formed as a protrusion on the fourth end face 323 is inserted into the first mating structure 311 formed as a groove on the second end face 313.

[0054] In some embodiments of the present invention, such as Figure 4 and Figure 5 shown, in the direction from the fixed end to the free end of the protrusion, the width of the protrusion gradually decreases. Thus, the two side end faces of the protrusion in the direction perpendicular to the fixed end to the free end have a certain inclination, which can play a guiding role. When the limit chute 31 and the support block 32 are in abutment, the two side end faces of the above-mentioned protrusion can guide the protrusion into the groove, which is beneficial to the cooperation between the first mating structure 311 and the second mating structure 321, thereby ensuring the limiting function of the limiting structure 3.

[0055] In some embodiments of the present invention, such as Figure 4 and Figure 5 shown, in the direction from the open end to the closed end of the groove, the width of the groove gradually decreases. Thus, the two side wall surfaces of the groove in the direction perpendicular to the open end to the closed end have a certain inclination, which can play a guiding role. When the limit chute 31 and the support block 32 are in abutment, the two side wall surfaces of the above-mentioned groove can guide the protrusion into the groove, which is beneficial to the cooperation between the first mating structure 311 and the second mating structure 321, thereby ensuring the limiting function of the limiting structure 3.

[0056] In some embodiments of the present invention, such as Figure 8 shown, the groove and the protrusion extend along the depth direction of the limit chute 31 or the thickness direction of the support block 32. The contact area where the side wall of the protrusion fits with the inner wall of the groove can be increased, and the stress generated by the protrusion and the groove under external force can be reduced, which helps to enhance the structural strength of the first mating structure 311 and the second mating structure 321, thereby enhancing the stability and reliability of the limit chute 31 and the support block 32. At the same time, the limiting effect generated by the cooperation between the first mating structure 311 and the second mating structure 321 can be improved, better solving the problem that the lens 2 is prone to sliding instability during limiting, and further improving the reliability and stability of the vehicle rearview mirror 100.

[0057] In some embodiments of the present invention, such as Figure 1, Figure 2 and Figure 3 as shown, in combination with Figure 7 and Figure 8 , a limit sliding groove 31 is provided on the lens 2, a support block 32 is provided on the temple 1, the lens 2 includes: a housing 21, a folding block 22 and a lens 23, the housing 21 is rotatably connected to the temple 1, the housing 21 has a mounting groove 215, the folding block 22 is installed in the mounting groove 215 and connected to the housing 21, the limit sliding groove 31 is provided on the folding block 22, and the lens 23 is provided on the housing 21 and together with the housing 21 defines an installation cavity 24. The structure is simple and reasonably arranged, facilitating the realization of the rotational connection between the lens 2 and the temple 1, and can ensure the unfolding and folding functions of the vehicle rearview mirror 100. By providing the folding block 22, it is convenient to process the limit sliding groove 31 that cooperates with the support block 32, which is beneficial to realizing the limiting function of the limiting structure 3, thereby preventing the lens 2 from rotating excessively relative to the temple 1 and causing the lens 2 to collide with the vehicle body or damaging the vehicle rearview mirror 100.

[0058] It can be understood that when the lens 2 rotates, the support block 32 and the temple 1 remain stationary relative to the vehicle body, and the housing 21, the lens 23, the folding block 22 and the limit sliding groove 31 on the folding block 22 perform a circumferential movement around the rotation axis of the lens 2 and the temple 1. Among them, the housing 21 includes a lens housing 211, a lens ring 212, a decorative cover 213 and a substrate 214, etc. The lens housing 211, the lens ring 212 and the decorative cover 213 are connected by snap connection. The lens housing 211, the lens ring 212, the decorative cover 213 and the lens 23 can form the overall appearance of the lens 2, which can shield and protect the component structure in the installation cavity 24. The lens 23 can expand the driver's view angle, facilitating the driver to observe the surrounding roads and vehicle conditions. At least one of the lens housing 211, the lens ring 212 and the decorative cover 213 is connected to the substrate 214, the mounting groove 215 is provided on the substrate 214, and the mounting groove 215 is a special-shaped cavity that can match the folding block 22.

Among them, the first driving component 4 may specifically be a first driving motor. There may be two first driving motors, respectively controlling the tilting movement of the lens 23 in the vertical and horizontal directions, thereby changing the angle of the lens 23 and the visible range of the vehicle rearview mirror 100.

At the same time, the operation is simple and convenient for assembly, and the detachable connection between the folding stopper 22 and the housing 21 can be realized, providing convenience for later maintenance. Among them, the housing 21 includes a base plate 214 and the installation cavity 24 is disposed on the base plate 214. The installation groove 215 is a special-shaped cavity that can match the folding stopper 22. Multiple first installation holes 221 may be provided on the folding stopper 22, and multiple second installation holes 216 corresponding to the multiple first installation holes 221 one by one are provided on the base plate 214.

The operation is simple and convenient for assembly.

[0061] In some embodiments of the present utility model, as Figure 2 and Figure 3 shown, a pin shaft 11 is provided on the mirror leg 1, and the lens 2 is rotatably connected to the pin shaft 11. The pin shaft 11 can connect the mirror leg 1 and the lens 2 together and ensure the relative position between the mirror leg 1 and the lens 2 is fixed. At the same time, it can transmit force and torque, allowing a certain relative rotation between the mirror leg 1 and the lens 2. The structure is simple and convenient for assembly, and can ensure the folding and unfolding functions of the vehicle rearview mirror 100.

[0062] In some embodiments of the present utility model, the vehicle rearview mirror 100 further includes a second driving assembly, which is disposed on the lens 2 or the mirror leg 1 and is used to drive the lens 2 to rotate relative to the mirror leg 1. Thus, the driver can, according to the road conditions and his own needs, electrically adjust to expand or fold the vehicle rearview mirror 100, so as to expand the rearview angle range, or achieve the purpose of protecting the lens 2, improving the passing performance of the vehicle and preventing the vehicle rearview mirror 100 from being scratched or collided without manual adjustment, greatly improving the convenience. Among them, the second driving assembly may specifically be a second driving motor, and the output shaft of the second driving motor may be connected to the lens 2 to provide a torque force for the rotation of the lens 2.

[0063] The vehicle according to the embodiments of the present utility model will be described below.

[0064] The vehicle according to the embodiments of the present utility model includes the rearview mirror of the above vehicle.

[0065] Specifically, as Figure 1 shown, in combination with Figure 2 and Figure 3 , the vehicle rearview mirror 100 includes a mirror leg 1, a lens 2, and a limiting structure 3. The lens 2 is rotatably disposed on the mirror leg 1, and the mirror leg 1 can be used to connect to the vehicle body, enabling the connection between the lens 2 and the vehicle body. The mirror leg 1 is fixedly disposed relative to the vehicle body, and the lens 2 can rotate around the rotation axis of the lens 2 and the mirror leg 1 to achieve the expansion and folding functions of the vehicle rearview mirror 100.

[0066] Further, the limiting structure 3 includes a limiting chute 31 and a support block 32. One of the limiting chute 31 and the support block 32 is disposed on the mirror leg 1, and the other is disposed on the lens 2. The limiting chute 31 is an arc extending in the circumferential direction along the rotation axis of the lens 2 and the mirror leg 1, and the support block 32 is slidably disposed in the limiting chute 31.

[0067] It can be understood that the support block 32 can slide in the arc-shaped limiting chute 31, and the limiting chute 31 extends in the circumferential direction along the rotation axis of the lens 2 and the mirror leg 1. Thus, the support block 32 can perform a circumferential movement around the rotation axis of the lens 2 and the mirror leg 1, that is, the limiting chute 31 and the support block 32 can rotate relative to each other around the rotation axis of the lens 2 and the mirror leg 1, thereby allowing the lens 2 and the mirror leg 1 to generate relative rotation to achieve the expansion and folding of the vehicle rearview mirror 100. At the same time, when the lens 2 rotates around the rotation axis of the lens 2 and the mirror leg 1 towards the front or the rear of the vehicle, the two end faces in the length direction of the limiting chute 31 can abut against the support block 32 to limit the rotation stroke of the lens 2. That is, the limiting structure 3 can be used to provide a limiting function to prevent the lens 2 from rotating excessively relative to the mirror leg 1, resulting in the lens 2 colliding with the vehicle body or causing damage to the vehicle rearview mirror 100.

[0068] Specifically, the two end faces in the length direction of the limit sliding groove 31 can be respectively denoted as the first end face 312 and the second end face 313. When the vehicle is driving normally, the vehicle rearview mirror 100 is in the unfolded state, and at this time, the support block 32 is spaced from the first end face 312 and the second end face 313. When the lens 2 is subjected to an external force such as manual or electric force, the lens 2 rotates, and relative movement occurs between the limit sliding groove 31 and the support block 32 in the circumferential direction of the rotation axis of the lens 2 and the mirror leg 1.

[0069] Assume that the limit sliding groove 31 is provided on the mirror leg 1 and is stationary relative to the vehicle body, and the support block 32 is provided on the lens 2. If the lens 2 is subjected to an external force towards the rear of the vehicle, the support block 32 slides towards the direction close to the first end face 312 of the limit sliding groove 31, and the limiting function of the limiting structure 3 is realized through the abutment between the first end face 312 and the support block 32, so that the rotation stroke of the lens 2 can be restricted, and it can be prevented that the lens 2 rotates excessively relative to the mirror leg 1 towards the rear of the vehicle and causes the lens 2 to collide with the vehicle body and be damaged; if the lens 2 is subjected to an external force towards the front of the vehicle, the support block 32 slides towards the direction close to the second end face 313 of the limit sliding groove 31, and the limiting function of the limiting structure 3 is realized through the abutment between the second end face 313 and the support block 32, thereby the rotation stroke of the lens 2 can be restricted, and it can be prevented that the lens 2 rotates excessively relative to the mirror leg 1 towards the front of the vehicle and causes the lens 2 to collide with the vehicle body or cause damage to the vehicle rearview mirror 100.

[0070] Wherein, at least one of the two end faces in the length direction of the limit sliding groove 31 is provided with a first matching structure 311, and at least one of the two opposite end faces of the support block 32 is provided with a second matching structure 321 that matches the first matching structure 311. One of the first matching structure 311 and the second matching structure 321 is a protrusion, and the other is a groove.

[0071] It can be understood that when the lens 2 rotates under the action of an external force, the two end faces in the length direction of the limit sliding groove 31 can abut against the support block 32 to realize the limit of the lens 2 in the circumferential direction of the rotation axis of the lens 2 and the mirror leg 1. At this time, the first matching structure 311 cooperates with the second matching structure 321, and the protrusion can be inserted into the groove, and the side wall of the protrusion can be attached to the inner wall of the groove. Thus, a force in the radial direction of the rotation axis of the lens 2 will be generated between the limit sliding groove 31 and the support block 32, thereby realizing the limit of the lens 2 in the radial direction of its rotation axis, which can better solve the problem that the lens 2 is prone to sliding instability during limiting, prevent the lens 2 from having slight movement in the radial direction of its rotation axis and causing the lens 2 to collide with the vehicle body and produce scratches, and can enhance the limiting effect of the limiting structure 3, and further improve the reliability and stability of the vehicle rearview mirror 100.

[0072] Among them, the cooperation between the first cooperation structure 311 and the second cooperation structure 321 is realized by a cooperation structure in which a protrusion is inserted into a groove. The structure is simple and easy to process, will not cause the production cycle to increase, and there is no need to additionally add other auxiliary components. For example, using double-stop limit and adding screw fixing limit, etc., will not increase the number of parts to be assembled, and can ensure low cost. On the other hand, the above structure will not be affected by the limitation of the layout space, nor will it increase the occupied volume of the limit structure 3. At the same time, whether the rotation of the lens 2 is driven by manual external force or by electric drive, the above limit structure 3 is applicable, and has the advantage of high versatility.

[0073] In addition, under the cooperation of the first cooperation structure 311 of the limit chute 31 and the second cooperation structure 321 of the support block 32, the side wall of the protrusion and the inner wall of the groove are mutually extruded, which can make the limit chute 31 and the support block 32 generate forces in the circumferential direction and the radial direction of the rotation axis of the lens 2 and the lens foot 1 at the same time, which can better offset the external force applied to the lens 2, reduce the risk of structural failure such as the support block 32, thereby reducing the probability of failure of the limit structure 3, and further reducing the possibility of the lens 2 hitting the vehicle body, and can extend the service life of the vehicle rearview mirror 100.

[0074] It should be noted that when the driver is driving in the vehicle, facing the front of the vehicle, the opposite side is the rear of the vehicle.

[0075] According to the vehicle of the embodiment of the present invention, by rotatably arranging the lens 2 on the lens foot 1, and making one of the limit chute 31 and the support block 32 of the limit structure 3 arranged on the lens foot 1, and the other arranged on the lens 2, and the support block 32 is slidably arranged in the arc-shaped limit chute 31, the unfolding and folding of the vehicle rearview mirror 100 can be realized, and the limit function of the rotation of the lens 2 can be realized, preventing the lens 2 from rotating excessively relative to the lens foot 1 and causing the lens 2 to collide with the vehicle body or causing damage to the vehicle rearview mirror 100. At the same time, by respectively arranging the first cooperation structure 311 and the second cooperation structure 321 that can cooperate with each other on the limit chute 31 and the support block 32, and one of the first cooperation structure 311 and the second cooperation structure 321 is a protrusion and the other is a groove, the limit effect can be enhanced, the limit of the lens 2 in the radial direction of its rotation axis can be realized, and the problem that the lens 2 is prone to sliding and instability during limiting can be better solved, preventing the lens 2 from rubbing against the vehicle body due to slight movement in the radial direction of the rotation axis, and further improving the reliability and stability of the vehicle rearview mirror 100. It can also reduce the risk of structural failure such as the support block 32 and extend the service life of the vehicle rearview mirror 100. And it has the advantages of simple structure, easy processing, low cost, small occupied space and high versatility.

[0076] In some embodiments of the present utility model, as Figure 6 shown, the rotation axes of the lens 2 and the temple 1 extend in the vertical direction. The rearview mirror has a use state. In the use state, the lens 2 can rotate forward by α1 degrees towards the front of the vehicle, where α1 satisfies: 60 ≤ α1 ≤ 90. When the vehicle rearview mirror 100 is in the use state and the lens 2 is subjected to an external force towards the front of the vehicle, the lens 2 can rotate towards the front of the vehicle around the rotation axes of the lens 2 and the temple 1 to avoid a hard collision between the lens 2 and an external object, thereby preventing damage to the vehicle rearview mirror 100, improving the safety of the vehicle rearview mirror 100 and extending its service life. For example, when the vehicle is reversing or the vehicle rearview mirror 100 accidentally collides with a person outside the vehicle, the lens 2 can rotate towards the front of the vehicle, thereby reducing the harm to the person outside the vehicle.

[0077] Among them, if α1 is greater than 90, the angle by which the lens 2 can rotate towards the front of the vehicle is too large, increasing the risk of the lens 2 colliding with the vehicle body. If α1 is less than 60, the angle by which the lens 2 can rotate towards the front of the vehicle is too small, and it is impossible to completely avoid a hard collision between the lens 2 and an external object. Therefore, 60 ≤ α1 ≤ 90 can not only ensure that there is no easy hard collision between the lens 2 and an external object, thereby reducing the risk of damage to the vehicle rearview mirror 100, but also prevent the angle by which the lens 2 rotates towards the front of the vehicle from being too large, thus avoiding the lens 2 colliding with the vehicle body.

[0078] In some embodiments of the present utility model, as Figure 6 shown, the rotation axes of the lens 2 and the temple 1 extend in the vertical direction. The rearview mirror has a use state. In the use state, the lens 2 can rotate backward by α2 degrees towards the rear of the vehicle, where α2 satisfies: 30 ≤ α2 ≤ 50. When the vehicle needs to pass through a narrow section or enter certain limited spaces, the lens 2 can rotate towards the rear of the vehicle around the rotation axes of the lens 2 and the temple 1 to achieve the folded state of the vehicle rearview mirror 100, thereby improving the passing performance of the vehicle and preventing the vehicle rearview mirror 100 from being scratched or collided. At the same time, after the vehicle rearview mirror 100 is folded, the space occupied by the vehicle will be reduced, which helps the driver park the vehicle in a parking lot or a narrow parking space. When the driver leaves the vehicle, the folded vehicle rearview mirror 100 can protect the lens 2 from unnecessary damage, such as being collided by other vehicles or pedestrians.

[0079] Among them, if α2 is greater than 50, the angle by which the lens 2 can rotate towards the rear of the vehicle is too large, increasing the risk of the lens 2 colliding with the vehicle body. If α2 is less than 30, the angle by which the lens 2 can rotate towards the rear of the vehicle is too small, and the folding angle of the vehicle rearview mirror 100 is too small. When the vehicle needs to pass through a narrow section or enter certain limited spaces, its passing rate is still limited, and the vehicle rearview mirror 100 is easily scratched or collided. Therefore, 30 ≤ α2 ≤ 50 can not only improve the passing rate of the vehicle through the narrow section, avoid the vehicle rearview mirror 100 from being scratched or collided, but also prevent the angle by which the lens 2 rotates towards the rear of the vehicle from being too large, thus preventing the lens 2 from colliding with the vehicle body.
