In the following description, many specific details are provided to provide a full understanding of the embodiments of the present application. However, those skilled in the art will appreciate that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps, etc. can be adopted.

[0030] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limiting the present application.

[0031] like Figures 1 to 3 As shown, the present embodiment provides a rearview mirror, comprising a rearview mirror body 1 and a guide assembly 2, wherein the guide assembly 2 is arranged on a side of the rearview mirror body 1 close to the vehicle window 3; the guide assembly 2 comprises a guide plate 21 and a driving mechanism 22, wherein the guide plate 21 may be a rectangular plate or a square plate, and the guide plate 21 is arranged vertically, then its two side plate surfaces face the rearview mirror body 1 and the vehicle window 3 respectively, and has a first end 211 and a second end 212 distributed front and back along the length direction of the vehicle; wherein the first end 211 of the guide plate 21 may be rotatably connected to the rearview mirror body 1 by a rotating shaft 23 or a hinged connection to realize rotation in the horizontal direction; the driving mechanism 22 is fixedly connected to the rearview mirror body 1, and the active end of the driving mechanism 22 is connected to the second end 212 of the guide plate 21, and can drive the guide plate 21 to rotate around the first end 211, so that the second end 212 approaches or moves away from the vehicle window 3. In this way, when rainwater hangs on the side window during the driving process of the vehicle and needs to be cleaned, the guide assembly 2 can be opened, and the guide plate 21 can be driven by the driving mechanism 22 to rotate around the first end 211, so that the second end 212 of the guide plate 21 is close to the direction of the window 3, thereby guiding the airflow flowing through the area, so that the high-speed airflow in the area impacts the window 3, thereby cleaning the water droplets or water film hanging on the window 3, and improving the safety of vehicle driving; at the same time, because the force points of the guide plate 21 are concentrated at the rotating connection when it is subjected to the impact of the airflow, on the one hand, it is easy to shake when it is subjected to the impact of the airflow, affecting the efficiency of clearing the accumulated water, and on the other hand, it will accelerate the material fatigue of the rotating shaft 23 and the guide plate 21, affecting their service life and posing the hidden danger of structural damage. Therefore, by connecting the active end of the driving mechanism 22 to the second end 212 of the guide plate 21, not only can the guide plate 21 be driven to rotate, but also the force concentrated at the rotating connection can be shared, providing a stable support for the guide plate 21, improving the efficiency of clearing the accumulated water on the side window and the service life of the guide assembly 2.

[0032] It can be understood that the movement stroke of the driving mechanism 22 can be set to four gears of zero, low, medium and high according to the light, moderate and heavy water hanging scenes, and the multi-speed control of the rotation angle of the guide plate 21 can be realized accordingly; when there is light water hanging in the area of ​​the side window used to observe the rearview mirror, the guide assembly 2 is turned on and adjusted to the low gear to rotate the guide plate 21 to the first angle α of any angle between 0 and 30 degrees; when there is moderate water hanging in the area of ​​the side window used to observe the rearview mirror, it is adjusted to the medium gear to rotate the guide plate 21 to the first angle α of any angle between 30 and 60 degrees; when there is heavy water hanging in the area of ​​the side window used to observe the rearview mirror, it is adjusted to the high gear to rotate the guide plate 21 to the first angle α of any angle between 60 and less than 90 degrees; when the water on the side window is cleared, the guide plate 21 rotates to the first angle α of 0 degrees, and the closing of the guide assembly 2 is completed. The first angle α can be understood as the angle between the surface of the guide plate 21 and the axis parallel to the length direction of the window 3. By controlling the movement stroke of the driving mechanism 22, the rotation angle of the guide plate 21 can be controlled to be less than 90 degrees at most to cope with different degrees of side window water hanging scenes.

[0033] In some embodiments, Figures 1 to 3 As shown, the rearview mirror body 1 defines an inner cavity 11, and a notch 12 connected to the inner cavity 11 is provided on one side of the rearview mirror body 1 close to the vehicle window 3; in this way, the driving mechanism 22 can be arranged in the inner cavity 11, and the rearview mirror body 1 is used to protect the driving mechanism 22, and the driving mechanism 22 can be built-in and hidden in the rearview mirror body 1 to reduce wind resistance, which is both beautiful and practical; at the same time, the active end of the driving mechanism 22 can extend out of the inner cavity 11 through the notch 12 to connect with the second end 212, thereby realizing the driving effect on the second end 212.

[0034] In some embodiments, Figure 2 and Figure 3 As shown, the guide plate 21 can also be set in the slot 12, that is, the first end 211 of the guide plate 21 is rotatably connected to the rearview mirror body 1 in the slot 12, so that the guide plate 21 can be stored in the slot 12 to reduce wind resistance when the guide assembly 2 is closed, and the slot 12 can be blocked to a certain extent by the guide plate 21, so that the inner cavity 11 at the slot 12 can be dustproof and waterproof.

[0035] For example, Figure 2 and Figure 3As shown, in this embodiment, the shell of the rearview mirror body 1 has a certain thickness, and the deflector 21 is rotatably connected with the rearview mirror body 1 in the slot 12, and a rotating shaft 23 whose axial direction is parallel to the height direction of the vehicle can be fixed at a position close to the first end 211 of the slot 12, and then the first end 211 is sleeved on the rotating shaft 23 to be rotatably connected with the rotating shaft 23. In this way, when the deflector assembly 2 is closed, the deflector 21 is received in the slot 12, and the inner and outer sides of the slot 12 are blocked; when the deflector assembly 2 is opened, the second end 212 of the deflector 21 rotates around the rotating shaft 23 in the horizontal direction and moves in the direction close to the vehicle window 3, and extends out of the slot 12 to guide the airflow to impact the water accumulated on the side window.

[0036] Furthermore, if Figure 2 As shown, the outer surface of the deflector 21 can be designed as follows: when the deflector 21 is received in the slot 12, the outer surface of the deflector 21 is flush with the outer surface of the side of the rearview mirror body 1 close to the vehicle window 3. In this way, the deflector 21 can be hidden inside the surface of the rearview mirror body 1, which can reduce wind resistance and be beautiful and practical.

[0037] In some embodiments, Figures 1 to 3 As shown, a partition 13 for separating the inner cavity 11 from the external environment is provided on one side of the slot 12 close to the inner cavity 11, and a deflector 21 is provided on one side of the partition 13 close to the vehicle window 3; the partition 13 is provided with a through hole 131 connecting the inner cavity 11 with the external environment, and the action end of the driving mechanism 22 extends out of the partition 13 through the through hole 131 to connect with the second end 212. In this way, when the deflector assembly 2 is opened, the partition 13 can be used to further block the inner and outer sides of the slot 12, so as to achieve dust and water resistance of the inner cavity 11 at the slot 12.

[0038] It is understandable that if Figure 3 and Figure 4 As shown, the through hole 131 is mainly used to prevent the partition 13 from interfering with the driving action of the driving mechanism 22 on the guide plate 21, and the size and shape of the through hole 131 can be designed and opened according to the type of the driving mechanism 22 and the moving path of the working end of the driving mechanism 22, so as not to interfere with the movement of the driving mechanism 22.

[0039] In some embodiments, Figure 2 and Figure 3As shown, the driving mechanism 22 includes a telescopic mechanism 221, one end of which is hinged to the rearview mirror body 1, and the other end of which is hinged to the second end 212. In this way, when the telescopic mechanism 221 is extended, the second end 212 of the deflector 21 can be pushed to move outward synchronously, so that the second end 212 of the deflector 21 rotates around the first end 211 in the horizontal direction and moves toward the direction close to the vehicle window 3, so as to guide the airflow to impact the water accumulated on the side window; when the telescopic mechanism 221 is retracted, the second end 212 of the deflector 21 can be pulled to move inward synchronously, so as to retract the deflector 21.

[0040] Furthermore, the telescopic mechanism 221 may adopt a pneumatic push rod, an electric push rod or a hydraulic push rod, and can control the rotation angle of the guide plate 21 to a maximum of less than 90 degrees by controlling the telescopic stroke to cope with different degrees of side window water hanging scenes.

[0041] It is understandable that the end of the telescopic mechanism 221 hinged to the rearview mirror body 1 can limit the hinge rotation direction of the telescopic mechanism 221 in the inner cavity 11 through a limit plate to improve the connection stability at the hinge and the smoothness during driving.

[0042] In some embodiments, Figure 4 and Figure 5 As shown, the driving mechanism 22 includes a linear reciprocating motion mechanism 222 and a connecting member 223. The linear reciprocating motion mechanism 222 can be a cylinder, a linear module, etc., which is fixedly connected to the rearview mirror body 1 in the inner cavity 11. One end of the connecting member 223 is fixedly connected to the action end of the linear reciprocating motion mechanism 222, and the other end of the connecting member 223 is slidably hinged to the second end 212. In this way, when the action end of the linear reciprocating motion mechanism 222 moves toward the direction close to the side window, the connecting member 223 can push the second end 212 of the deflector 21 to move outward synchronously, so that the second end 212 of the deflector 21 rotates around the first end 211 in the horizontal direction and moves toward the direction close to the vehicle window 3, so as to guide the airflow to impact the water accumulated on the side window; when the action end of the linear reciprocating motion mechanism 222 moves toward the direction away from the side window, the connecting member 223 can pull the second end 212 of the deflector 21 to move inward synchronously, so as to retract the deflector 21.

[0043] It is understandable that the sliding hinge between the other end of the connecting member 223 and the second end 212 can be achieved by Figure 4 and Figure 5 The structural form shown is achieved by providing a horizontally arranged slide groove 213 at the second end 212 of the guide plate 21, and providing a slider 214 that can slide along the slide groove 213 in the slide groove 213, and then hinged the other end of the connecting member 223 to the slider 214, that is, completing the sliding hinge between the connecting member 223 and the second end 212, so that the guide plate 21 can be smoothly pushed and pulled.

[0044] In addition, an embodiment of the utility model also provides a vehicle, including the rearview mirror in the above embodiment. For other structures and working principles of the rearview mirror, please refer to the above description of the embodiment of the vehicle door. Since the rearview mirror has the above technical effects, the vehicle with the rearview mirror should also have the corresponding technical effects, which will not be repeated here.

[0045] In some embodiments, the vehicle is equipped with a control unit for controlling the start or shut down of the drive mechanism 22. The drive mechanism 22 is electrically connected to the control unit. The control unit is a vehicle system or a switch triggered by physical action. When the control unit is a vehicle system, the control unit can be operated by voice control; when the control unit is a switch, the control unit can be operated by a physical switch or touch screen button set in the cockpit. The control unit can be used to control the start, shut down and travel of the drive unit in the cockpit, and then the deflector 21 can be controlled at multiple gear angles to cope with different degrees of side window water hanging scenes.
