[0016] 2. When a lot of dust appears on the lens of the rearview mirror, press the electronic button in the cab, the mirror body deflects toward the direction of the car body, the lens approaches the fan, and the gas generated by the fan rotation blows toward the mirror surface, causing the dust to fall downward.

DETAILED DESCRIPTION

[0025] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0026] In one embodiment, Figure 1-Figure 7 As shown:

[0027] The present embodiment provides a rearview mirror for an automobile, comprising a mirror body 1, a mirror seat 2 is provided at one end of the mirror body 1, a support 3 is connected to one end of the mirror seat 2, a storage compartment 4 is installed at one end of the support 3, a connecting seat 5 is provided at one end of the storage compartment 4, a force unloading assembly 6 is provided on the storage compartment 4, the force unloading assembly 6 comprises at least two shafts 7 arranged in the storage compartment 4, an inertia bearing 15 is mounted on the shaft 7, an idler wheel 8 is fixed on the outer ring of the inertia bearing 15, all the idlers 8 are connected to each other by at least one belt 9, an impeller 10 is installed on at least one idler wheel 8, and the force unloading assembly 6 also comprises A first guide plate 11 is fixed on the outer side of the storage chamber 4, an air inlet 12 is opened on the windward side of the storage chamber 4, the air inlet 12 is communicated with the inner cavity of the storage chamber 4, the outer end of the air inlet 12 passes through the first guide plate 11 and communicates with the guide surface of the first guide plate 11, and the inner end of the air inlet 12 faces the blades on the impeller 10. When the car is running, the gas from the windward side is blown to the outer side of the storage chamber 4, and after being collected by the first guide plate 11, it is blown to the blades in the storage chamber 4 through the air inlet 12, so that the impeller 10 rotates with the idler wheel 8, and then the idler wheel 8 is transmitted downward with the belt 9;

[0028] An air outlet 13 communicating with the inner cavity of the storage chamber 4 is opened upward from the bottom side thereof, and the air outlet 13 is vertically downward. The impeller 10 and the belt 9 driving the impeller 10 are both located above the air outlet 13. A gap channel 14 is formed between the storage chamber 4 and the air outlet 13. When the belt 9 is conveyed downward, the gas is released into the gap channel 14, and finally discharged vertically downward from the air outlet 13.

[0029] A driven idler wheel 22 is mounted on one of the shafts 7 , and the driven idler wheel 22 is in transmission contact with the belt 9 . A fan 23 is mounted on the driven idler wheel 22 , and the fan 23 is located outside the opposite side of the windward surface of the accommodating chamber 4 .

[0030] When the rearview mirror is in use, the support 3 is fixed to the car through the connecting seat 5, and the mirror body 1 is fixed to the car by the support 3 through the mirror base 2. When the car is driving, airflow blows on the windward surface of the mirror body 1, the mirror base 2, the support 3 and the storage compartment 4 (hereinafter collectively referred to as the rearview mirror), wherein most of the airflow is obtained by the first guide plate 11, and is transmitted upward along the guide surface between it and the upper components, and then enters the storage compartment 4 through the air inlet 12, and forms air pressure at the top of the inner cavity of the storage compartment 4, and the air pressure blows to the blades to rotate the impeller 10, and the impeller 10 drives the upper idler wheel 8 to rotate, and the upper idler wheel 8 drives the belt 9 downward to drive the lower idler wheel 8 to rotate, and the lower idler wheel 8 drives the shaft rod 7 to rotate, and the shaft rod 7 drives the fan 23 to rotate, and a large amount of airflow is transmitted to the air outlet 13 at the bottom of the storage compartment 4 through the belt 9, and is released downward through the air outlet 13. It can be seen that the gas blown onto the windward surface of the rearview mirror during driving of the car enters the storage compartment 4 and is then released downward through the air outlet 13, thereby reducing the resistance of the airflow to the rearview mirror.

[0031] The first deflector 11 can guide the airflow blowing onto the windward surface of the rearview mirror and quickly release it into the storage compartment 4 through the air inlet 12, and then quickly release it downward through the air outlet 13 through the force unloading assembly 6 in the storage compartment 4, and the release direction is downward, thereby further reducing the resistance of the airflow to the rearview mirror.

[0032] In addition, Figure 2 As shown, part of the airflow is also applied to the idler wheel 8, which is transmitted by the idler wheel 8 with the belt 9, and then the belt 9 rotates the bottom shaft 7 and is applied to the driven idler wheel 22 installed on the bottom shaft 7. The driven idler wheel 22 rotates with the fan 23 through the extension rod. Through this mechanical transmission method, the resistance airflow collected in the storage compartment 4 is released. By observing the rotation speed of the fan 23, the size of the airflow on the windward side of the car when it is driving can be known. Since the greater the speed of the car, the greater the airflow on the windward side, the driver can be reminded to slow down by observing the rotation speed of the fan 23, thereby achieving the purpose of safe driving.

[0033] like Figure 3As shown, a second guide plate 17 is installed on the windward surface of the mirror base 2 and the storage cabin 4, and the second guide plate 17 is horizontal. When the mirror base 2 rotates forward with the mirror body 1 until the windward surface of the mirror body 1 and the windward surface of the storage cabin 4 are on the same surface (during normal use), the second guide plate 17 and the first guide plate 11 overlap seamlessly on the left and right. At this time, the setting of the second guide plate 17 increases the guide area of ​​the first guide plate 11. When airflow is blown into the windward surface of the mirror body 1, in addition to being concentratedly infused into the air inlet 12 through the first guide plate 11, more airflow is also transported toward the direction of the first guide plate 11 through the second guide plate 17, so that more airflow is collected into the storage cabin 4 through the air inlet 12.

[0034] like Figures 5 to 7 As shown, the storage cabin 4 extends upward on the right side of the mirror body 1, and the first guide plate 11 is an L-shaped bent plate, which is divided into a horizontal section 18 connected to the windward surface of the storage cabin 4 and corresponding to the second guide plate 17 on the left and right, and is divided into a bending section 19 connected to the right end of the horizontal section 18 and extending upward along the height direction of the windward surface of the storage cabin 4. A wind collecting hood 20 is fixed to the top of the bending section 19, and the wind collecting hood 20 covers the outside of the air inlet 12. The wind collecting hood 20 penetrates into the storage cabin 4, and the opening of the wind collecting hood 20 faces downward. A part of the wind collecting hood 20 is exposed in the first guide plate 11, and the opening faces the guide surface of the first guide plate 11, and the other part of the wind collecting hood 20 covers the storage cabin 4, and the opening faces the blades on the impeller 10. The external airflow blows onto the first guide plate 11, is guided by the first guide plate 11, and then flows into the air inlet 12. After being collected by the half of the wind collecting hood 20 located in the first guide plate 11, it is then poured into the storage chamber 4 through the air inlet 12. After being collected by the half of the wind collecting hood 20 in the storage chamber 4, it is blown downward along the inner cavity of the storage chamber 4 to the blades, causing the impeller 10 to rotate effectively.

[0035] The shaft 7 equipped with a driven idler wheel 22 extends to the outside of the opposite side of the windward surface of the accommodating compartment 4 for installing a fan 23. When a large amount of dust appears on the lens of the rearview mirror, the electronic button in the cab is pressed to deflect the mirror body 1 toward the vehicle body, that is, when the mirror holder 2 rotates with the mirror body 1 until the mirror surface is close to the vehicle body, the lens approaches the fan 23. At this time, the blades on the fan 23 are located in the direction of the tangential surface of the lens. At this time, the gas generated by the rotation of the fan 23 blows toward the mirror surface, causing the dust to fall downward. The rotational power of the fan 23 comes from the driven idler wheel 22 on the bottom side, the rotational power of the driven idler wheel 22 comes from the belt 9, the rotational power of the belt 9 comes from the idler wheel 8 on the top side, the rotational power of the idler wheel 8 on the top side comes from the impeller 10, and the rotational power of the impeller 10 comes from part of the airflow blowing on the rearview mirror when the car is driving. It can be seen that during the driving of the car, the driver can quickly clean the dust on the mirror surface by adjusting the rearview mirror to the door direction through the electronic button, without manual cleaning, and this action can be completed during driving. In addition, in order to rotate the fan 23, no additional motor is required, and the airflow collected in the storage compartment 4 can be quickly released outward through mechanical transmission. After the rearview mirror is cleaned, it can be quickly returned to the angle of the rearview field through the electronic button, which will not greatly affect the driving process.

[0036] Figure 5 As shown, when the mirror base 2 rotates with the mirror body 1 to make the mirror body 1 close to the vehicle body (when deflected and stored), the second deflector 17 is separated from the first deflector 11 by about 90 degrees. When the mirror base 2 adjusts the viewing angle with the lens relative to the door direction, the second deflector 17 will not affect the rotation of the mirror base 2.

[0037] like Figure 3 As shown, the windward surface of the mirror body 1 is provided with an inclined surface 21, which is located on the opposite side of the mirror base 2. When the car is driving, the airflow blowing onto the windward surface of the mirror body 1, a small part of which is directed to the storage compartment 4 through the first guide plate 11 and the second guide plate 17, and most of the airflow is directly reduced by the inclined surface 21. It can be seen that the storage compartment 4 in the present invention is not only used to discharge another part of the airflow through the above-mentioned mechanical method, but also mainly collects this part of the airflow into the storage compartment 4, which is used to drive the fan 23 to rotate, so that the rearview mirror is pressed Figure 5 When the lens is turned to the car side, the mirror surface is blown and dusted by the fan 23.

[0038] like Figure 4As shown, the connection seat 5 is arranged along the height direction of the accommodation compartment 4, and a connection hole 16 is opened on the connection seat 5. When the rearview mirror is installed on the vehicle body, it is connected to the vehicle by using the connection hole 16. Of course, if the rearview mirror is an electronic rearview mirror, the rearview mirror will also have wires, which are connected to the vehicle control system, so that the mirror body 1 can adjust the angle forward and backward around the support 3 in the driving direction of the vehicle through the mirror seat 2. This electronic adjustment of the angle of the mirror body 1 to achieve a change in the field of view is a prior art, and the present invention will not repeat it.

[0039] 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.

[0040] 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.
