When the rearview mirror is manually pulled, the palm is located on the inclined surface of the back of the mirror shell at the same time. After the rearview mirror is deflected to the side of the vehicle body, the side of the vehicle body provides support force to the front of the mirror shell, and the palm provides pressure to the outer end of the rubber sleeve, forcing the rubber sleeve to push the handle of the switch valve. The handle rotates downward to open the switch valve, and the gas in the collection tube enters the two branches of the branch pipe and is sprayed onto the mirror surface through the nozzles on the two branches, so that the rearview mirror can achieve the purpose of cleaning the lens at the same time when it is stored, ensuring that the surface of the lens is clean and still has a high-definition effect when it is used next time. When cleaning the lens, it is a synchronous action completed when the rearview mirror is deflected to the side of the vehicle body for storage, which is convenient for operation. Because the lens is deflected to the side of the vehicle body with the rearview mirror and the mirror side is buckled into the mirror shell after the face is flipped over, it not only ensures that the lens is effectively cleaned, but also is in a relatively closed space after cleaning, preventing dust from attaching again when the vehicle is not moving. Before the vehicle moves, the rearview mirror is rotated to the outside of the vehicle body, and the lens can also be kept clean without the need for secondary wiping.

The nozzles 11 are distributed on the rear side of the mirror frame 4, and a synchronization component is provided at the inner end of the mirror housing 1, which includes a driven wheel 12 fixed on the inner end of the rotating shaft 7, a driving wheel 13 connected to the inner end of the mirror handle 2, and a belt 14 connected between the driven wheel 12 and the driving wheel 13. The top surface of the mirror base 3 is a plane, and a vertically upward assembly shaft 15 is welded on the plane, and the mirror handle 2 is connected to the plane of the mirror base 3 through the assembly shaft 15; when the mirror handle 2 rotates backward with the mirror housing 1 to be in the same straight line with the mirror base 3, the driving wheel 13 rolls and contacts on the plane of the mirror base 3, and at the same time, the rotating shaft 7 and the driven wheel 12 are away from the front side of the mirror base 3; conversely, when the mirror handle 2 rotates forward with the mirror housing 1 to be close to the vehicle body, the driving wheel 13 rolls backward along the plane to the rear side of the mirror base 3, and drives the driving wheel 13 to complete a 180-degree rotation at the same time through the belt 14.

[0024] A first one-way valve 19 is installed on the air inlet pipe 10. The collecting pipe 9 is bonded to the rear wall of the inner cavity of the mirror housing 1. The collecting pipe 9 is a rubber bellows. The collecting pipe 9 is flat before being filled with gas, and becomes elliptical after being filled with gas and expanded.

[0025] A branch pipe 16 is connected to the end of the collecting pipe 9 extending into the rotating chamber 8. The branch pipe 16 is divided into two branches, an upper branch and an lower branch. A plurality of nozzles 11 are connected to the upper branch, and a plurality of nozzles 11 are connected to the lower branch. The nozzles 11 on the upper branch are inclined downward, and the nozzles 11 on the lower branch are inclined upward. The upper branch of the branch pipe 16 is connected to the upper edge of the collecting pipe 9, and the lower branch of the branch pipe 16 is connected to the lower edge of the collecting pipe 9.

[0026] An air vent pipe 18 extends upward from the bottom of the mirror handle 2 , and a second one-way valve 20 is installed on the air vent pipe 18 . The rated opening pressure of the second one-way valve 20 is greater than the rated opening pressure of the first one-way valve 19 .

[0027] A slope 24 is provided on the back of the mirror housing 1, and an operating hole 21 is opened on the back of the mirror housing 1 by the slope 24. The operating hole 21 is located on the rear side of the branch pipe 16. A switch valve 22 is fixed on the branch pipe 16. The valve handle of the switch valve 22 faces backward and close to the operating hole 21. A rubber sleeve 23 is installed on the rear side of the operating hole 21. The rubber sleeve 23 is a tapered sleeve that gradually tapers toward the back. The handle of the switch valve 22 passes through the operating hole 21 and enters the rubber sleeve 23, and presses against the inner wall of the rubber sleeve 23.

[0028] Working principle and effect: In actual use, the inner end of the mirror seat 3 is fixed on one side of the vehicle body. During the driving process of the car, the airflow on the windward side acts on the back of the mirror housing 1. As the car accelerates, the impact pressure of the airflow increases. When the air pressure of the airflow is greater than the rated opening pressure of the first one-way valve 19, part of the gas will be injected into the collecting pipe 9 through the intake pipe 10. The collecting pipe 9 is in a flat state (deflated) when no airflow is injected. As the gas is continuously injected, the collecting pipe 9 will gradually expand. When the gas pressure in the collecting pipe 9 is greater than the rated opening pressure of the second one-way valve 20, the second one-way valve 20 will open, and the excess gas will be discharged through the vent pipe. 18 is vented (pressure relief) to the outside, ensuring that the collecting pipe 9 collects gas while preventing the collecting pipe 9 from bursting. When decelerating and stopping, the airflow on the windward surface is greatly reduced. At this time, the airflow pressure on the windward surface is less than the rated opening pressure of the first one-way valve 19. The first one-way valve 19 is closed, and the intake pipe 10 stops injecting gas into the collecting pipe 9. At the same time, the air pressure in the collecting pipe 9 is less than the rated opening pressure of the second one-way valve 20. The second one-way valve 20 is also closed. At this time, the gas collected in the collecting pipe 9 is no longer vented to the outside through the vent pipe 18. After stopping, the driver habitually pulls the outer end of the rearview mirror (mirror housing 1) to deflect the rearview mirror to the side of the vehicle body. As the rearview mirror deflects backward, the mirror handle 2 will lead the driving wheel 13 to deflect backward along the top plane of the mirror base 3. The driving wheel 13 will automatically rotate under the friction of the top surface of the mirror base 3. At the same time, the driving wheel 13 drives the driven wheel 12 to rotate through the belt 14, and the driven wheel 12 rotates with the shaft 7. When the inner end of the mirror handle 2 rotates to the rear side of the mirror base 3, the shaft 7 leads the connecting seat 6 and the lens 5 to complete a 180-degree rotation up and down. The driving wheel 13 is detached from the top surface of the mirror base 3, and the driving wheel 13 is no longer rotated by friction. The shaft 7 also stops rotating with the lens 5. At this time, the lens 5 rotates 180 degrees with its mirror surface facing backward, and then The rear view mirror 1 is rotated forward with the back side (back side) facing forward. During this operation, the palm of the hand pushes on the inclined surface 24 on the back side of the mirror housing 1, and the rearview mirror is deflected to the side of the vehicle body and then stops. The palm of the hand continues to provide thrust to the outer end of the rubber sleeve 23, and the rubber sleeve 23 pushes the handle of the switch valve 22 to make the handle rotate downward and open the switch valve 22. At this time, the gas compressed in the collecting tube 9 will enter the two branches of the branch pipe 16 under the action of air pressure, and will be sprayed onto the mirror surface from the upper and lower directions through the nozzles 11 on the two branches, so that the dust attached to the mirror surface during driving can be automatically cleaned, ensuring that the mirror surface is clean and tidy when the lens 5 is used next time, and still plays its high-definition effect. In addition, the cleaning of the lens 5 is a synchronous action completed when the rearview mirror is deflected and stored toward the side of the vehicle body, so it is easy to operate.Furthermore, since the lens 5 is deflected to the vehicle body side along with the rearview mirror and the mirror side is buckled into the mirror housing 1 after the face is flipped over, it is not only ensured that the lens 5 is effectively cleaned, but also that the lens 5 is in a relatively closed space (rotating cavity 8) after cleaning, which prevents dust from attaching again when the vehicle is not moving. Before the vehicle moves, the rearview mirror is rotated back to the outside of the vehicle body, and the lens 5 can also be kept clean without the need for secondary wiping.

[0029] like Figure 4 , Figure 7 As shown, a damping sleeve 17 is installed at the inner end of the mirror housing 1, and one end of the rotating shaft 7 passing through the mirror housing 1 is assembled on the damping sleeve 17, and a rubber layer is provided on the top plane of the mirror base 3. After the rotating shaft 7 rotates 180 degrees, even if the driving wheel 13 is separated from the top surface of the mirror base 3 and no longer rotates (the driving wheel 13 loses the friction effect, so the driving wheel 13 no longer rotates), under the damping effect of the damping sleeve 17, the rotating shaft 7 is prevented from inertial rotation, ensuring that the mirror surface side faces the nozzle 11 at this time.

[0030] like Figure 7 As shown, through another embodiment, the opening method of the switch valve 22 is disclosed, the frame 4 surrounds the outer edge of the lens 5, and the frame 4 protrudes forward, the lens 5 is deeply sunken in the frame 4, the frame 4 is spliced ​​by a plurality of frame units 25, the frame unit 25 is connected to the mirror housing 1 through a swivel seat, a connecting rod 26 is provided in the rotating chamber 8, one end of the connecting rod 26 is connected to the frame unit 25, and the other end is connected to the switch valve 22. After the rearview mirror is deflected toward the side of the vehicle body, when the front of the mirror frame 4 is pressed toward the side of the vehicle body, the side of the vehicle body will be lifted toward the front of the mirror frame 4 under the reaction, forcing the free ends of these mirror frames 4 to rotate into the mirror housing 1. When one of the mirror frames 4 rotates inward, it will push the connecting rod 26, and the other end of the connecting rod 26 will trigger the switch valve 22 to automatically open. At this time, the mirror frame unit 25 is used to form a closer contact relationship with the side of the vehicle body, so that the lens 4 is buckled in a relatively closed environment to prevent dust from adhering, and the mirror frame unit 25 can also be used to control the opening and closing of the switch valve 22.

[0031] The mirror frame unit 25 is connected to the mirror housing 1 via a swivel seat. The swivel seat referred to here is a torsion spring type swivel seat, that is, when the front of the mirror frame unit 25 leaves the vehicle body side, it can also automatically rotate because the vehicle body side no longer provides a reaction force to it, and at the same time, use the reverse pulling force of the connecting rod 26 to rotate the valve handle of the switch valve 22 to close. The torsion spring type swivel seat is composed of a torsion spring and a swivel seat, which is relatively common and will not be described in detail.

[0032] The bottom area of ​​the lens housing 1 is provided with a discharge hole, or a mesh structure is adopted, and when the attached matters on the lens 5 are cleaned downward by the nozzle 11, they are discharged outward from the discharge hole or the mesh.

[0033] The above orientation designations do not represent the specific orientations of the components in this implementation scheme. This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures. In essence, the specific orientations of the components are described according to their actual installation and actual use as well as the customary orientations of technicians in this field. This is hereby explained.

[0034] The specific implementation methods described above further describe the invention purpose, technical solutions, and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the protection scope of the present invention. It is particularly pointed out that for those skilled in the art, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
