The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] Please refer to Figures 1 to 5 The embodiment of the utility model provides a rearview mirror for an autonomous driving vehicle, comprising a rearview mirror housing 1, wherein one end of the rearview mirror housing 1 is provided with a connecting handle 2, wherein the connecting handle 2 is connected to a vehicle body at an end away from the rearview mirror housing 1, and comprises:

[0032] The lens mechanism 3 includes a main lens 31 and a connecting component provided between the main lens 31 and the inner wall of the rearview mirror housing 1. The connecting component has a first space inside. The main lens 31 has a first state and a second state. When in the first state, Figure 1 As shown, the main lens 31 is located inside the rearview mirror housing 1. When in the second state, as shown in FIG. Figure 2 As shown, the main lens 31 extends out of the rearview mirror housing 1 along a first direction, wherein the first direction is Figure 1 The front-to-back direction in

[0033] The monitoring mechanism 5 is located in the first space when the main lens 31 is in the first state, and extends out of the first space along a second direction when the main lens 31 is in the second state, so as to monitor the road environment around the vehicle, wherein the second direction is perpendicular to the first direction, and the second direction is Figure 2 The up and down directions in

[0034] A driving mechanism 4, provided on the connecting assembly, for driving the main lens 31 to switch between the first state and the second state;

[0035] The driving mechanism 4 drives the main lens 31 in the lens mechanism 3 to move forward and backward, driving the monitoring mechanism 5 to switch between the two states of storage and extension, so that the monitoring mechanism 5 will not be exposed to the outside for a long time, causing dust to adhere to the lens.

[0036] In some embodiments, the connecting assembly includes an inner box body 32 connected to the back end of the main lens 31, the inner box body 32 has the first space inside, the inner box body 32 is covered with an outer box body 33, and the outer box body 33 is connected to the inner wall of the rearview mirror housing 1 away from the end of the main lens 31;

[0037] like Figure 3 As shown, the main lens 31 is installed by inserting the inner box body 32 into the outer box body 33. In addition, under the restriction of the outer box body 33, the inner box body 32 and the main lens 31 can stably move along the first direction.

[0038] In some embodiments, the monitoring mechanism 5 includes a second notch 56 penetrating the bottom end of the inner box body 32, and a transparent box 51 disposed in the second notch 56 and movable along the second direction;

[0039] When the main lens 31 is in the second state, the bottom of the transparent box 51 extends out of the first space through the second notch 56, and a first monitor 52 is provided at the bottom of the transparent box 51. The first monitor 52 is used to monitor the road environment of the transparent box 51 away from the side of the rearview mirror housing 1 along the first direction. A second monitor 53 is provided above the first monitor 52. The second monitor 53 is used to monitor the road environment of the transparent box 51 away from the side of the connecting handle 2 along a third direction. The third direction, the second direction and the first direction are perpendicular to each other.

[0040] like Figure 4 and Figure 5 As shown, wherein the third direction is Figure 1In the left and right directions, after the main lens 31 switches from the first state to the second state, the second slot 56 will move out of the outer box body 33, and the transparent box 51 will fall downward through the second slot 56 without the support of the outer box body 33. The lens of the first monitor 52 faces rearward, and the lens of the second monitor 53 faces away from the vehicle body. The images captured by the two will be transmitted to the vehicle control system for analysis.

[0041] In some embodiments, an inclined block 54 is provided at the end of the transparent box 51 away from the main lens 31, and the end of the inclined block 54 away from the main lens 31 has a first inclined surface, and the first inclined surface is inclined from bottom to top in a direction away from the transparent box 51;

[0042] like Figure 4 and Figure 5 As shown, during the process of the main lens 31 switching from the second state to the first state, as the inner box body 32 moves toward the inside of the rearview mirror housing 1, the outer box body 33 will abut the first inclined surface, so that the inclined block 54 and the transparent box 51 move upward, completing the storage of the transparent box 51, the first monitor 52 and the second monitor 53.

[0043] In some embodiments, a baffle 55 is provided on the top of the transparent box 51 and the inclined block 54. When the main lens 31 is in the second state, the bottom surface of the baffle 55 abuts against the inner surface of the inner box body 32.

[0044] like Figure 4 As shown, the baffle 55 is in contact with the inner box body 32 to prevent the transparent box 51 from completely separating from the inner box body 32 .

[0045] In some embodiments, a third notch 8 is formed at the bottom of the outer box body 33 near the main lens 31, and the third notch 8 has a second inclined surface at the end away from the main lens 31, and the second inclined surface is parallel to the first inclined surface;

[0046] like Figure 3 and Figure 4 As shown, during the process of the main lens 31 switching from the second state to the first state, the outer box body 33 pushes the transparent box 51 to move upward through the second inclined surface, so that the transparent box 51 is more stable during the upward and downward movement, reducing the possibility of the transparent box 51 getting stuck.

[0047] In some embodiments, the driving mechanism 4 includes a first notch 41 provided at the middle of the top of the outer box body 33, an actuator is provided at the top of the inner box body 32 corresponding to the first notch 41, and a driving unit is provided at the top of the outer box body 33, and the driving unit is used to drive the actuator to drive the inner box body 32 and the main lens 31 to move along the first direction;

[0048] like Figure 3 and Figure 4 As shown, by providing the first notch 41 , the driving part can contact the actuator, and then the driving mechanism 4 drives the main lens 31 to move by the cooperation of the driving part and the actuator.

[0049] In some embodiments, the actuator is a rack 42 extending in the first direction, the driving unit includes an electric motor 44 disposed at the top of the outer box body 33, the output shaft of the electric motor 44 is provided with a driving gear 45, the driving gear 45 is provided with a driven gear 43 on a side close to the main lens 31, and the driving gear 45 and the rack 42 are both meshed and transmission-connected with the driven gear 43;

[0050] like Figure 3 and Figure 4 As shown, a short shaft passes through the middle of the driven gear 43, and both ends of the short shaft are fitted with connecting pieces, the bottom end of the connecting piece contacts the top of the outer box body 33, and the connecting pieces are respectively located on the left and right sides of the first notch 41, to ensure the stable rotation of the driven gear 43. When the electric motor 44 drives the driving gear 45 to rotate, the driven gear 43 is driven to rotate through meshing, and the driven gear 43 drives the rack 42 to move along the first direction through meshing, thereby realizing the functions of the driving part and the actuator. In addition, the diameter of the driving gear 45 is larger than that of the driven gear 43, so that the driving gear 45 and the electric motor 44 can be placed in the middle of the outer box body 33. When the main lens 31 is in the first state, the driving gear 45 will not interfere with the main lens 31. The smaller driven gear 43 is arranged at the edge of the outer box body 33 to ensure that the length of the rack 42 is fully utilized and will not interfere with the main lens 31.

[0051] In some embodiments, a wiping cloth 57 is disposed on the side wall of the second notch 56, and the outer surface of the transparent box 51 is in contact with the surface of the wiping cloth 57;

[0052] like Figure 5As shown, during the upward or downward movement of the transparent box 51, the wiping cloth 57 will wipe the surface of the transparent box 51. Even if the transparent box 51 extends out of the inner box body 32 and is contaminated with dust during the automatic driving process, it will be wiped by the wiping cloth 57 for easy use next time. Before automatic driving, the main lens 31 can also be driven to move multiple times to make the transparent box 51 move up and down reciprocatingly to ensure that there is no dust attached to the surface of the transparent box 51.

[0053] In some embodiments, a dust cover 7 is provided at the top edge of the outer box body 33, and the dust cover 7 is connected to the inner wall of the rearview mirror housing 1 away from the end of the outer box body 33. The electric motor 44 is covered by the dust cover 7 to reduce damage to the electric motor 44 caused by external dust or water stains, thereby increasing the service life of the electric motor 44.

[0054] In some embodiments, when the main lens 31 is in the first state, a convex mirror 9 is provided on the side of the main lens 31 away from the connecting handle 2, and the outer surface of the convex mirror 9 away from the main lens 31 is connected to the inner wall of the rearview mirror housing 1;

[0055] like Figure 1 As shown, when the driver does not use automatic driving, the driver can observe more road environment through the convex mirror 9, which is convenient for the driver to drive the vehicle better. Further, as Figure 4 As shown, a sealing edge 6 is bonded around the inner wall of the rearview mirror housing 1, and the outer surface of the convex mirror 9 away from the main lens 31 is connected to the sealing edge 6. When the main lens 31 is in the first state, its side surfaces are all in contact with the sealing edge 6 to reduce dust from entering the interior of the rearview mirror housing 1.

[0056] Usage process: When the automatic driving is not required, the main lens 31 is in the first state, such as Figure 1As shown, the driver can observe the road environment through the main lens 31 and the convex mirror 9. When automatic driving is required, the electric motor 44 is started, and the electric motor 44 drives the driving gear 45 to rotate, and drives the driven gear 43 to rotate through meshing. The driven gear 43 drives the rack 42 and the inner box body 32 to move along the first direction through meshing. During the movement of the inner box body 32, the first inclined surface contacts the second inclined surface, and the transparent box 51 slowly falls downward. When the main lens 31 switches to the second state, the baffle 55 contacts the inner box body 32 to prevent the transparent box 51 from completely separating from the inner box body 32. At this time, the electric motor 44 drives the driving gear 45 to rotate, and drives the driven gear 43 to rotate through meshing. The driven gear 43 drives the rack 42 and the inner box body 32 to move along the first direction. During the movement of the inner box body 32, the first inclined surface contacts the second inclined surface, and the transparent box 51 slowly falls downward. When the main lens 31 switches to the second state, the baffle 55 contacts the inner box body 32 to prevent the transparent box 51 from completely separating from the inner box body 32. The first monitor 52 and the second monitor 53 capture images of the side and rear of the vehicle and transmit them to the vehicle-mounted control system for analysis, wherein the electric motor 44, the first monitor 52 and the second monitor 53 are all powered by the vehicle-mounted power supply, and start and stop are achieved through the vehicle-mounted control system; finally, when the automatic driving function is stopped, the electric motor 44 drives the driving gear 45 to rotate in the opposite direction, so that the inner box body 32 is retracted into the outer box body 33. During the retraction process, the transparent box 51 is pushed by the second notch 56, and the second inclined surface abuts against the first inclined surface, so that the transparent box 51 moves upward and is stored back into the inner box body 32, waiting for the next use.
