[0030] The first connecting rod 9 and the pressing plate 13 are connected to the floating mechanism 5, and the first connecting rod 9 causes the pressing plate 13 to float on the surface of the adsorbent cotton 12 through the floating mechanism 5. Specifically:

[0031] The floating mechanism 5 includes a first guide rail 501 arranged perpendicular to the mirror side 101 of the shell 1, a first slider 502 slidably installed on the first guide rail 501, and a first rotating block 503 and a second rotating block 504 rotatably installed on both sides of the first slider 502. The first rotating block 503 is provided with a first guide groove 505, and the second rotating block 504 is provided with a second guide groove 506. The first connecting rod 9 is limitedly slidably connected in the first guiding groove 505. A second connecting rod 508 is also installed in the mirror cavity 4 through a second hinge shaft 507, and one end of the second connecting rod 508 is limitedly slidably installed in the second guiding groove 506. The first guiding groove 505 and the second guiding groove 506 are provided to enable the first connecting rod 9 and the second connecting rod 508 to adapt to the change of the horizontal distance between the rotating shaft and the first slider 502 during rotation.

[0032] A second slider 509 is slidably mounted on the other end of the second connecting rod 508, and a third connecting rod 510 is hingedly mounted on the second slider 509, and a third guide groove 511 is provided on one side of the filter chamber 17 close to the pressure plate 13 to provide guidance for the vertical lifting of the third connecting rod 510.

[0033] In addition, the air outlet of the filter chamber 17 is connected to the first exhaust duct 25, and a first air guide groove 22 is provided at one end of the mirror side 101 of the shell 1 to which the endoscope 2 is connected. The exhaust air of the first exhaust duct 25 is guided by the first air guide groove 22 to be aligned with the endoscope 2.

[0034] The air outlet of the filter chamber 17 is connected to the second exhaust duct 26, the outer side of the endoscope 2 is installed with a fan-shaped guide plate 23 through the first hinge shaft 8, the first connecting rod 9 is connected to the fan-shaped guide plate 23, the exterior mirror 3 is installed on the front end side of the fan-shaped guide plate 23, the outer end of the shell 1 is constructed as an arc-shaped guide portion 103 that slides with the arc-shaped outer wall of the fan-shaped guide plate 23, and a second air guide groove 24 is provided on the fan-shaped guide plate 23 on the outer side of the exterior mirror 3. The exhaust air of the second exhaust duct 26 is guided by the second air guide groove 24 to be aligned with the exterior mirror 3.

[0035] The housing 1 is connected to a mirror column 27, the inner end of the mirror column 27 is hingedly mounted on a mirror mounting plate 28, and the mirror mounting plate 28 is mounted on a vehicle door. The windward side 102 of the housing 1 after contraction does not exceed both sides of the vehicle edge.

[0036] The working principle of the device of the present invention is:

[0037] When the vehicle is parked, the mirror column 27 is rotated so that the housing 1 of the rearview mirror is hidden at the door side to prevent other vehicles from colliding with the rearview mirror, thereby protecting the rearview mirror.

[0038] After starting the car, the rearview mirror installed on the mirror column 27 is ejected. When the car is running, the incoming wind can enter the mirror cavity 4 through the vent 7 and the air inlet 16 on the windward side 102 of the housing 1.

[0039] In the acceleration state, the wind entering from the vent 7 enters the airbag 10, causing the volume of the airbag 10 to increase. Figure 2 As shown, when the volume of the airbag 10 increases, the airbag 10 will squeeze the inner end of the first connecting rod 9. When the squeezing force of the airbag 10 on the inner end of the first connecting rod 9 overcomes the pressure of the compression spring 6 on the outer end of the first connecting rod 9, the compression spring 6 will be compressed, causing the volume of the water bag 20 to decrease, and the cleaning liquid in the water bag 20 will be squeezed into the adsorbent cotton 12 in the filter chamber 17 along the hydrophobic pipe 15. At the same time, the inner end of the first connecting rod 9 pressed down by the airbag 10 will cause the first slider 502 to descend along the first guide rail 501, and the distal end of the second connecting rod 508 rotatably connected to the first slider 502 will rotate along the second hinge shaft 507, so that the third connecting rod 510 movably connected to the proximal end of the second connecting rod 508 rises under the guidance of the third guide groove 511, and the pressing plate 13 connected to the lower end of the third connecting rod 510 leaves the surface of the adsorbent cotton 12, so that the adsorbent cotton 12 can absorb the cleaning liquid transported from the water bag 20.

[0040] During driving, the gas in the adsorption cotton 12 that enters the filter chamber 17 through the ventilation duct 18 along the air inlet 16 is filtered by the adsorption cotton 12 and enters the first air guide slot 22 along the first air exhaust duct 25. Under the guidance of the first air guide slot 22, the air is blown toward the endoscope 2. The air will also enter the second air guide slot 24 along the second air exhaust duct 26. Under the guidance of the second air guide slot 24, the air is blown toward the exterior mirror 3 to blow away the moisture and dust on the surfaces of the endoscope 2 and the exterior mirror 3. At the same time, during the rotation of the first connecting rod 9, the fan-shaped guide plate 23 at its far end will rotate with the first hinge shaft 8 as the pivot axis under the guidance of the arc-shaped guide part 103, and the fan-shaped guide plate 23 will rotate toward the inside of the arc-shaped guide part 103, prompting the exterior mirror 3 installed on the fan-shaped guide plate 23 to further unfold, so that the driver can obtain a larger field of view through the exterior mirror 3, which is convenient for accurate judgment when changing lanes.

[0041] It should be noted that when the vehicle accelerates, the expansion value of the airbag 10 in the speed range of 0-20km / h is too small to compress the compression spring 6, so that the fan-shaped guide plate 23 and the outside mirror 3 remain stationary; when the speed is in the range of 20-60km / h, as the speed increases, the airbag 10 gradually increases until it reaches the maximum state. During this process, the first connecting rod 9 compresses the compression spring 6 and drives the fan-shaped guide plate 23 and the outside mirror 3 to rotate around the first hinge shaft 8 until they reach the maximum angle; when the vehicle speed exceeds 60km / h, the airbag 10 no longer continues to expand, but the airbag 10 can withstand the air pressure at the vehicle's extreme speed. At this time, the fan-shaped guide plate 23 and the outside mirror 3 remain stationary at the maximum angle.

[0042] When the vehicle speed slows down, the air flow pressure decreases, such as Figure 1 As shown, the pressure of the airbag 10 on the inner end of the first connecting rod 9 is not enough to overcome the pressure of the compression spring 6 on the far end of the first connecting rod 9, the gas in the airbag 10 will partially overflow, the inner end of the first connecting rod 9 will rotate upward, the volume of the water bag 20 will increase, and negative pressure will be formed in the water bag 20. Under the action of the negative pressure, the cleaning liquid enters the water bag 20 along the water inlet pipe 11. Combined with the speed increase, the water in the water bag 20 is squeezed out, thereby realizing the automatic replenishment and transportation of the cleaning liquid in the water bag 20.

[0043] At the same time, as the airbag 10 is lifted, the inner end of the first connecting rod 9 will prompt the first slider 502 to rise along the first guide rail 501, and the distal end of the second connecting rod 508 rotatably connected to the first slider 502 will rotate along the second hinge axis 507, so that the third connecting rod 510 movably connected to the proximal end of the second connecting rod 508 will descend under the guidance of the third guide groove 511, and the pressure plate 13 connected to the lower end of the third connecting rod 510 will squeeze the adsorption cotton 12, and the cleaning liquid of the dust adsorbed by the adsorption cotton 12 after filtering the air will be discharged from the drain port 14 of the filter chamber 17, thereby realizing the irregular cleaning of the adsorption cotton 12.

[0044] At the same time, under the pressure of the compression spring 6, the fan-shaped guide plate 23 will rotate outward with the first hinge shaft 8 as the pivot axis under the guidance of the arc-shaped guide part 103, causing the outside mirror 3 installed on the fan-shaped guide plate 23 to fold inward, so that the driver can observe the situation at the rear wheels or the rear of the car through the outside mirror 3.

[0045] During the process of vehicle speed reduction, when the vehicle speed drops to 60km / h, the exterior mirror 3 maintains a fixed maximum angle. When the speed drops from 60km / h to 20km / h, the exterior mirror 3 returns to a minimum angle under the action of the airbag 10 and the compression spring 6. From 20km / h until the car stops, the exterior mirror 3 maintains a constant minimum angle.

[0046] The advantage of the present invention is that the angle of the outside mirror 3 outside the inner mirror 2 can be automatically adjusted according to the change of vehicle speed, so as to adjust the field of vision according to the requirements of the driving state; during the adjustment process, when the speed is low, the angle of the outside mirror remains unchanged to assist in observing the situation at the rear of the vehicle; when the speed increases in the moderate speed range, the angle of the outside mirror gradually increases to a maximum, which assists in expanding the field of vision; when the speed exceeds this range, the angle of the outside mirror remains at the maximum, and the wind force after filtering dust is used to clean the mirror surface; the adsorbent cotton 12 used for filtering dust will also be cleaned by the clean water automatically supplied as the vehicle speed changes, and the impurities are squeezed out, thereby reducing the cost of later maintenance of the rearview mirror to achieve the above functions.

[0047] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
