[0049] When the fourth camera 302, the fifth camera 3 and the second camera 301 fail or are delayed during driving, the user can start the two electric push rods 504 inside the rearview mirror base 1, and push the extrusion piston 501 through the electric push rods 504, so that the extrusion piston 501 squeezes the water inside the water chamber 5, thereby pushing the water in the water chamber 5 into the piston hole 503 through the drainage groove 502, and lifting the piston b505 with the help of water pressure, and using the two connecting rods 506 to move upward, thereby moving the mirror 507 out of the placement groove 109. At this time, the user can observe the situation behind the vehicle through the mirror 507.

[0050] Furthermore, when the user has finished using the mirror 507 and needs to retract the mirror 507, the user can control the two electric push rods 504 to retract, so that the water flows back into the water cavity 5, thereby retracting the mirror 507 into the placement groove 109. At the same time, the user can close the solenoid valve on the guide tube a403, open the solenoid valve on the guide tube b405, and start the air compressor to produce high-pressure gas, and then introduce the high-pressure gas into the guide tube b405 and the multiple branch pipes 406 through the air inlet pipe 404, so that the high-pressure gas enters the air cavity 101 respectively, and squeezes the piston a102 inside the air cavity 101, so that the piston a1 02 squeeze the connecting block 103 and push the mounting block 105 toward the mirror 507, so that the scraper 108 contacts the surface of the mirror 507, and then cleans the dust or sand attached to the surface of the mirror 507. The cleaned dust will fall into the collection chamber 107 along the beveled edge of the top of the scraper 108. In addition, when it is necessary to clean the dust or sand in the collection chamber 107, the user can unscrew the screws on the top of the cover 110 and remove the cover 110, and then remove the screws on the top of the collection block 106, remove the collection block 106, and then clean the dust or sand inside the collection chamber 107.

[0051] In addition, by setting up multiple springs 104, when the air compressor stops running and the solenoid valve of the guide pipe a403 is opened to release the gas inside the multiple air cavities 101, a force can be applied to the piston a102 to make the scraper 108 detach from the mirror 507 and reset.

[0052] Among them, dust shielding components are provided on both sides of the upper cover 2, and the dust shielding components include: limit blocks 6 fixedly connected to both sides of the upper cover 2, limit rings 601 are provided on the top of the two limit blocks 6, and connecting rings a602 are sleeved on the outer sides of the two limit rings 601, and one side of the two connecting rings a602 is fixedly connected to a U-shaped bracket b608; fixed threaded knobs 609 are provided on both sides of the U-shaped bracket b608, and threaded positioning holes b701 matching with the fixed threaded knobs 609 are provided on both sides of the rearview mirror base 1, and the upper cover 2 is provided with a A threaded positioning hole a7 that matches with the fixed threaded knob 609; a connecting ring c606 that is sleeved on the outside of the two limiting rings 601, the top of the two connecting rings c606 is fixedly connected with a U-shaped bracket a607, one side of the two limiting rings 601 is fixedly connected with a connecting ring b605, one side of the two connecting rings b605 is fixedly connected with a limiting sealing plate 604, a dust shielding cloth a8 is provided between the U-shaped bracket b608 and the U-shaped bracket a607, and a dust shielding cloth b801 is provided between the U-shaped bracket a607 and the limiting sealing plate 604.

[0053] When there is no need to use the dust cover a8 and the dust cover b801 to cover the category five camera 3, the category two camera 301 and the category four camera 302, the user can pull the U-shaped bracket b608 and the U-shaped bracket a607 to the top of the limiting sealing plate 604, align the fixed threaded knobs 609 on both sides of the U-shaped bracket b608 with the threaded positioning holes a7 and screw them in, thereby folding the dust cover a8 and the dust cover b801.

[0056] Here’s how it works:

[0057] When in use, the user can capture real-time images of the rear and sides of the vehicle through the fourth camera 302 and the second camera 301, and transmit them to the display screen inside the vehicle, so that the user can clearly observe the situation behind and on the sides of the vehicle.

[0058] In order to clearly capture the situation behind and to the sides of the vehicle, the cameras in the electronic rearview mirrors are mostly exposed. In rainy or dusty weather, the lenses of these cameras are easily adhered to dust or rain, affecting the user's observation. At this time, the user can open the solenoid valve on the guide tube a403, close the solenoid valve on the guide tube b405, and start the air compressor installed in the vehicle. The air compressor produces high-pressure gas, which is introduced into the high-pressure nozzle 401 with the help of the intake pipe 404, and then the high-pressure gas is sprayed onto the lenses of the fourth camera 302 and the second camera 301 through the guide nozzles 402 on both sides of the high-pressure nozzle 401, so as to blow away the dust and rain on the lenses.

[0059] When the fourth camera 302, the fifth camera 3 and the second camera 301 fail or are delayed during driving, the user can start the two electric push rods 504 inside the rearview mirror base 1, and push the extrusion piston 501 through the electric push rods 504, so that the extrusion piston 501 squeezes the water inside the water chamber 5, thereby pushing the water in the water chamber 5 into the piston hole 503 through the drainage groove 502, and lifting the piston b505 with the help of water pressure, and using the two connecting rods 506 to move upward, thereby moving the mirror 507 out of the placement groove 109. At this time, the user can observe the situation behind the vehicle through the mirror 507.

[0060] Furthermore, when the user has finished using the mirror 507 and needs to retract the mirror 507, the user can control the two electric push rods 504 to retract, so that the water flows back into the water cavity 5, thereby retracting the mirror 507 into the placement groove 109. At the same time, the user can close the solenoid valve on the guide tube a403, open the solenoid valve on the guide tube b405, and start the air compressor to produce high-pressure gas, and then introduce the high-pressure gas into the guide tube b405 and the multiple branch pipes 406 through the air inlet pipe 404, so that the high-pressure gas enters the air cavity 101 respectively, and squeezes the piston a102 inside the air cavity 101, so that the piston a1 02 squeeze the connecting block 103 and push the mounting block 105 toward the mirror 507, so that the scraper 108 contacts the surface of the mirror 507, and then cleans the dust or sand attached to the surface of the mirror 507. The cleaned dust will fall into the collection chamber 107 along the beveled edge of the top of the scraper 108. In addition, when it is necessary to clean the dust or sand in the collection chamber 107, the user can unscrew the screws on the top of the cover 110 and remove the cover 110, and then remove the screws on the top of the collection block 106, remove the collection block 106, and then clean the dust or sand inside the collection chamber 107.
