[Problems to be solved by conventional techniques and devices]

 General average income rises daily, public transportation develops, and private small cars grow rapidly due to the demand of busy commercial and industrial societies.Many people drive a car.Safe driving is the first priority. . Accidents in heavy rain, where speeding traffic accidents always occur, are even more likely to occur, which makes the rear-view mirror's field of view an important part for the driver.

The structure of a conventional rearview mirror is made up of one support body A and a mirror B which can be rotated by an angle as shown in FIG. When rainwater or snow falls on the mirror, the surface blurs and adversely affects the left and right vision, and misjudgment for the driver causes serious injury, so it is not possible to neglect from a safety standpoint. There is an attempt to improve the above-mentioned drawbacks, for example, there is a wire to remove fog, but it does not work very well in heavy rain and snow. Also, some of them have a small brush attached, but the mirror surface is so small that the field of view is rather blurred, so the effect is not sufficient. Because of the various drawbacks described above, the creators have studied for a long time and improved the design of the left and right rearview mirrors to a safe structure, and after many tests, have created a product that can be put to practical use. We applied for patents in both the United States and Germany and finally obtained the patents.

[Means for Solving the Problems]

 The present invention has been proposed in order to achieve the above object, and the main purpose of the present invention is to provide a structural product for removing water and snow from a rearview mirror of an automobile. Using the headwind while the car is running, it guides to the flow guide plate and changes the headwind flow. The wind removes water droplets on the mirror surface, and when the speed of the car slows down and the wind power is insufficient, a horizontal fan is activated to blow the air sucked from the frame holes on the bottom side of the mirror frame stand into wind power. The amount of air blown out by the L-shaped wind guide plate is guided to the flow guide plate and blown to the mirror to strengthen the wind force. By doing this, water, fog, snow, etc. on the mirror surface can be completely and completely removed regardless of whether the vehicle is running fast or slowly. This is one of the main purposes.

Another object of the present invention is to provide a rectangular guide plate at the upper end of the mirror frame support in front of the mirror, and to provide several saw-like shapes in the vertical direction of the guide surface of the guide plate. is there. There is a θ-angle slope in the direction of the car window, which is saw-shaped. In addition, there is an arc surface at the end of the conducting plate that is mainly in contact. The slope and arc surface of the flow guide plate and the mirror surface present 90 ° θ, and since they are in the same direction as the vehicle body, the mirror surface of the vehicle rearview mirror and the vehicle body form a 90 ° θ angle. Therefore, by controlling the rotation of the guide plate with a small motor, the reverse wind is blown toward the mirror surface that guides the saw-like slope and arc surface of the wind guide plate while the vehicle is running, and the wind does not blow to the outside of the mirror frame base. . Therefore, since the guide plate guides the wind and blows it completely onto the mirror surface, water drops and snow on the mirror surface are removed.

[Examples and effects]

 First, a detailed description will be given with reference to FIGS. 2, 3, and 4. This is a structure for removing water and snow from a rear-view mirror of an automobile, which mainly comprises a mirror frame 1, a mirror 2, a rectangular guide plate 5 and a box 3.

Mirror 2: There is a concave groove 12 on the upper side surface of the front mirror frame base 1, and a notch 121 at the front end of the concave groove 12 has one shaft hole 13 on each of the upper end of the outer surface of the mirror frame base 1, and a guide plate. 5 is in the groove 12. The flow guide surface 5 of the flow guide plate 5 has several sawtooths 52 in the vertical direction. There is a θ-angled slope 53 toward the car window direction of the serrated shape 52, and an arc face 54 is formed at a position where the main end of the guide plate 5 extends. The upper slope of the flow guide plate 5 and the arc surface 54 are in the same direction as the vehicle body, and there is a convex main shaft 55 at the front side end of the flow guide plate 5. Mirror 2 rearward Mirror frame 1 There is a plate 14 that leads to a suitable position on the outer side of the outer side of the mirror and guides the inside of the L-shaped wind, and there are several frame holes on the bottom side of the mirror frame 1. 15 and the box 3 inside the mirror frame 1 on the side near the front seat window. It is a rectangular groove seat 36, which is fixed to the side frame 361 on the side of the mirror frame base 1, and a side lid 37 is fixed to the groove seat 36 to form a box shape 3. A stopper is provided at the upper end of the inner side surface near the mirror frame base, and two main spindle gears 363, 364 are provided at appropriate points on the inner side so as to face the box 3. Further, there is a small motor 1 that is tightly locked to the inner side surface of the mirror frame base 1 near the groove seat 36 of the box shape 3. There is a gear G1 of the main shaft, and the intermediate gear G2 of the main shaft gear 363 between the stationary groove seat 36 and the side lid 37 in which the gear G1 meshes meshes with the inner intermediate gear G2 via the box shape 3, and the main shaft of the transmission guide plate 5 The small gear G3, which is the main contact with 55, and another main shaft 55 of the flow guide plate 5 are cut into the shaft hole 13 on the outside of the mirror near the upper end of the outer surface of the mirror frame base. There is a fixed drive motor M 2 on the inner surface of 36. The shaft of the drive motor M2 appears on the inner side surface 362 of the hollow groove seat 36. Further, there is a main gear G4 at the front end of the shaft, and the gear G4 meshes with the other main shaft gear 364 between the groove seat 36 and the side lid 37 for localization. The intermediate gear G5 of the row type fan 8 meshes again with the inner intermediate gear G5 through the box shape 3, and the gear G6 of the main contact of the rotary shaft 81 of the row type fan 8 and the other end of the rotary shaft 81 of the row type fan 8 are removed. The shaft hole inside the mirror 2 enters from the upper end of the outer surface of the mirror frame 1.

Next, referring to FIGS. 4 and 5, this is controlled by a small motor M1 of the flow guide plate 5 and a driving motor M2 of the horizontal fan 8 using two power switches. When traveling at a normal high speed, the transmission is performed via the gear G2 of the small motor M1 and the small gear G3 of the main guide plate 5 and the rotating guide plate 5 are rotated to incline the guide plate 5 to the required angle. The guide plate 5 that guides the headwind when the vehicle 7 is running to the desired air volume of the mirror surface is caught on one edge close to the box shape 3, and the stopper on the upper end of the side surface of the mirror surface due to the box shape 3 Maximum tilt angle. The mirror surface 2 of the rear-view mirror of the automobile 7 and the vehicle body have a 90 ° θ angle. The inclined surface 53 and the arc surface 54 of the flow guide plate 5 and the mirror surface 2 form a 90 ° θ angle. That is, when the automobile 7 running in the same direction as the vehicle body travels, the headwind blows along the guide plate 5 toward the slope 53 of the sawtooth 52, the arc surface 54, the mirror surface 2, and when running slowly. Head wind is weak. At this time, the gear G4 at the front end of the rotary shaft is moved by the drive motor M2 of the row-type fan 8, and the row-type fan 8 is rotated by the rotary gear G6 of the intermediate gear G5 transmission row-type fan 8 again. The outside air is sucked in through the frame hole 15 and blown out by the rotating blades of the fan. The L-shaped tilted wind guide blades 14 guide the amount of air blown out to the flow guide plate 5 and strengthen the wind force on the mirror surface. Even when the car 7 runs late and the wind power is insufficient, water drops and snow on the mirror surface 2 are completely removed. In this way, the surface of the back mirror 2 can be kept clean regardless of whether the vehicle is running fast or slow.

As described above, the structure of the present invention completely cleans the surface of the mirror regardless of the traveling speed of the vehicle.
