Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric retractable door mirror used for a vehicle or the like.

[0002]

2. Description of the Related Art In recent automobiles, door mirrors are standard equipment as outside mirrors. These door mirrors are superior to conventional fender mirrors, and are longer than the conventional fender mirrors. Because it is mounted with a large outward projection, a large space is required when transporting a car or putting it in a garage. Means are provided so as to be stowed inside the maximum width of the car. In this storage structure, there are a structure which is manually operated and a structure which is automatically operated. However, in the case of the manual operation, it is necessary to step down from the car each time and operate, which is painful in rainy weather or the like. For this reason, an electric retractable door mirror that uses an electric motor as a drive source and allows the mirror body to be returned and stored by remote control from inside the vehicle is used. As this type of electric retractable door mirror, a mirror body is rotatably mounted on a pivot shaft fixed to a mounting base mounted on a door. Therefore, the mirror body is turned around the fixed pivot shaft from the return position (the position used during operation) projecting substantially perpendicular to the door, and is stored so as to be substantially parallel to the door side. It is folded and stored at the position. A positioning mechanism is provided between the mirror body and the door, so that the mirror body is fixed to the door at the return position. Further, a motor and a reduction gear group built in the rotating body fixed to the mirror body are connected to a pivot shaft fixed to the mounting base, and the mirror body is fixed to the mounting base by the operation of the motor. And the mirror body at the storage position can be automatically rotated to the return position. A switch mechanism for detecting a mirror body position around the pivot shaft is disposed between the pivot shaft fixed to the mounting base and the mirror body. When the switch mechanism detects that the mirror body has moved from the storage position to the return position, the motor is automatically stopped.

[0003] Further, since the door mirror is located outside the vehicle unlike the rearview mirror, fog and water droplets adhere to the mirror surface, and the visibility may be reduced. Therefore, as a technique for removing water droplets, in the case of door mirrors, a mirror with a heater that heats the mirror surface to evaporate moisture, or a piezoelectric vibrator is adhered to the back of the mirror, and the mirror vibrates finely when an electric current flows through it. There is an ultrasonic raindrop removal mirror that drops water droplets on the mirror surface, and in the case of side windows, water droplets attached to the side window near the mirror hinder the rear view of the door mirror, so that side window wipers or side windows that remove water droplets Some dovetails have a washer nozzle that removes dirt from the dough.

[0004]

However, in this kind of conventional vehicle, first, a driver checks the condition of a car or traffic behind from a position of a rearview mirror or a door mirror.
It is convenient to check the gap between the rear car and the facing object and the grounding condition of the rear wheels.However, the situation and safety in front of the other side can be checked visually through the windshield. It was inconvenient to check the gap between the vehicle and the object facing the vehicle and the grounding state of the front wheels, and it was extremely inconvenient especially when there was no person in the passenger seat. For this reason, when driving for the first time on a village road or a narrow passage in the city, wheels may be dropped into a gutter, or when passing between other vehicles or buildings in a narrow passage, the side of the car may be contacted. Even if a danger such as a property damage accident is foreseen, it is difficult to confirm the degree of avoiding a car, so that there is a problem that the vehicle is operated with intuition with vague safety confirmation.

Secondly, when visibility becomes difficult due to the adhesion of granular or mist-like moisture to the glass surfaces of the left and right door mirrors and side windows, it is necessary to directly remove the cloth, paper, etc. by hand to remove it. Each time, you have to go out of the car or open the window to reach out. Of course, the treatment of the driver's side door mirror and side window glass is troublesome, but especially when there is no passenger other than the driver, the treatment of the passenger side door mirror and side window glass is extremely troublesome. In particular, there is a problem that the treatment is inconvenient on a rainy or snowy day or a cold season. For this reason, various methods have been considered to remove the particulate and mist-like water adhering to the left and right door mirrors and the side window glass.However, mirrors with heaters that heat the surface to evaporate the mist and water have a tendency to adhere to the fog. It works well when it's raining, but it's not powerful enough to evaporate falling water drops in rainy weather.

Further, when viewing the door mirror through the side window, as shown in FIG. 10, to prevent the fog or water droplets adhering near the glass of the side window from obstructing the rear view of the door mirror. Wiper 5
8 is excellent in removing fog and water droplets, but the movement of the wiper 58 reciprocating on the glass surface of the side window 57 obstructs the driver's line of sight and adversely affects the rearview of the door mirror 59. Had the disadvantage of causing
In the case where a washer nozzle is provided to remove dirt attached to the side window 57, it is inconvenient in terms of replenishing water. The ultrasonic raindrop removing mirror that drops water drops has a problem that it does not run off unless the attached moisture becomes large to some extent. In addition, there is a general problem that it is difficult to escape from the vehicle when the vehicle falls into the water by mistake while driving. The present invention provides a rear view function of a conventional electric retractable door mirror and a function of rotating a storage position and a return position to a front view function for confirming a situation near a vehicle side in front of the mirror. It is a technical object to provide an electric retractable door mirror device provided with a function of removing fog and water droplets adhering to a mirror surface of a door mirror and a glass surface of a side window and a safety measure against an emergency.

[0007]

In order to achieve the above object, a water drop removing door mirror system according to the present invention is stored in a main air reservoir mounted on a lower part of a vehicle body from an air compressor installed in a hood or the like of an automobile. The compressed air is decompressed to a pressure effective for removing water droplets through the regulating valve and stored in the auxiliary air reservoir, and the mirror surface of the first mirror body, the mirror surface of the second mirror body, and the glass of the side window The compressed air for the air ejection unit that removes fog and water droplets adhering to the surface is guided from the auxiliary air reservoir to the first solenoid valve, the second solenoid valve, and the third solenoid valve. The air hose connected to the first solenoid valve is connected to the air intake of the first air ejection unit attached to the lower surface of the opening of the first mirror body of the electric rotary door mirror, and the second solenoid valve is connected to the auxiliary movable arm. The other third solenoid valve is connected to the air intake of the third air ejection unit attached to the lower surface of the opening of the second mirror body. You. The driver can freely operate the solenoid valves,
The first nozzle provided in the first air chamber of the first air ejection unit and the compressed air ejected from the third nozzle provided in the third air chamber of the third air ejection unit cause the mirror surface of the first mirror body The fog and water droplets adhering to the mirror surfaces of the first and second mirror bodies are directly removed to ensure good after-image and pre-image characteristics of the mirrors of the first and second mirror bodies for safe operation. However, when checking the situation in front and behind by the mirror of the first mirror body and the mirror of the second mirror body through the side window, fog and water droplets adhere to the glass surface of the side window In such a case, since the visibility is significantly impaired, the movable arm is turned to the retracted position, and the compressed air ejected from the second nozzle provided in the second air chamber of the second air ejection unit is used.
Fog and water droplets adhering to the glass surface of the side window are removed, so that the front view and the rear view by the mirror surface of the first mirror body and the mirror surface of the second mirror body can be kept good. The outlet of the quick replenishment valve of the water drop removal door mirror system is provided inside the vehicle via a pneumatic filter, and is connected to an air hose connected to a device such as an oxygen inhalation mask or aqualung.

[0008] The electric rotary door mirror of the main body has a first pivot shaft erected at the tip of the main movable arm, and a first air ejection unit for removing water droplets of the first mirror attached to the lower surface of the opening. A motor and a reduction gear group disposed on the first rotating body side that is inserted into the second boss of the first rotating body fixed to the mirror body and connected to the worm wheel loosely inserted into the first pivot shaft, By driving the motor, the first mirror body is rotated around the first pivot shaft to the foreground position and the rearward position,
A third air for removing water droplets of a second mirror is provided at a base end of a main movable arm of a movable arm composed of an auxiliary movable arm having a main movable arm and a second air ejection unit for a side window attached to an inner surface on one side. The second rotating body of the second mirror body in which the ejection unit is mounted on the lower surface of the opening is fixed, and the second pivot shaft, which is erected on the base base mounted on the mounting base, is fixed to the second end of the main movable arm base end. The movable arm is rotated between the retracted position and the return position about the second pivot shaft by driving the motor through the boss.

[0009]

With the electric retractable door mirror device configured as described above, when the motor disposed on the first rotating body is rotated,
The first rotating body of the electric rotary door mirror of the main body attached to the tip of the main movable arm is loosely inserted into the first pivot shaft and fixed to the U plate and the upper washer by a spring. As the motor and the reduction gear group revolve around the first mirror body, the first mirror body rotates between the foreground position and the rearward position about the first pivot shaft. On the other hand, the second rotator and the second mirror body fixed to the base end of the main movable arm are slowly inserted into the second pivot shaft when the reduction gear group is rotated by the motor disposed on the second rotator. As a result, the motor and the reduction gear group revolve around the worm wheel fixed to the second pivot shaft by the urging force of the spring on the U plate and the upper washer, and the movable arm is moved to the second pivot. It can rotate between the return position and the storage position about the support shaft. The driver turns a first rotating body fixed to the first mirror body and a second rotating body fixed to the movable arm by a remote switch or a controller (not shown) operated from the driver's seat, respectively. In order to obtain an appropriate field of view by the first mirror body, it is used by rotating between the foreground position and the rearward position. In addition, the second mirror body is rotated and adjusted about the second pivot shaft in advance in accordance with the position of the driver's eyes before driving so as to reflect and capture the image of the first mirror body. However, the combined action of the first mirror and the second mirror makes it possible to easily grasp a wide range of traffic conditions between the front and the rear.

In the case where the rear view or the front view is obstructed by fog or water droplets attached to the mirror surface of the first mirror body or the second mirror body in rainy weather or dense fog, a remote switch or controller operated in a driver's seat (Not shown), the first solenoid valve is opened, compressed air is sent from the air hose to the air intake of the first air ejection unit, and the first air is ejected from the first nozzle provided in the first air chamber. Removes fog and water droplets adhering to the mirror surface of the mirror body, opens the third solenoid valve and sends compressed air from the air hose to the air intake of the third air ejection unit, and the third nozzle provided in the third air chamber Mist and water droplets adhering to the mirror surface of the second mirror body are removed by the compressed air ejected from the When the rear view or the forward view is obstructed by the mirror surface of the first mirror body or the mirror surface of the second mirror body, the movable arm is moved to the retracted position by a remote switch or a controller (not shown) operated in the driver's seat. After turning, the third solenoid valve is opened to send compressed air from the air hose to the air intake of the second air ejection unit provided on the side of the auxiliary movable arm, and the mist adhering to the glass surface of the side window And water droplets are removed by compressed air ejected from a third nozzle provided in the third air chamber. In this way, it is possible to improve the visibility of the mirrors of the first mirror body and the second mirror body viewed through the glass of the side window.

Further, since a disaster occurs at an unexpected time, a water drop removing door mirror system which is an essential requirement of the present invention is utilized. For this reason, if an outlet is provided inside the vehicle via a pneumatic filter from the quick replenishment valve of the water droplet removal door mirror system, for example, a face mask such as an oxygen inhalation mask or aqua lang is connected to the tip of the air hose and kept in the vehicle, If a car accidentally falls into the water and gets trapped in a sealed car and the door cannot be opened immediately and breathing becomes difficult, the intake environment inside or outside the company deteriorates, or as a life-saving treatment for people who have difficulty breathing due to an accident When breathing is necessary, the amount of air can be replenished, so that effective emergency treatment can be performed.

There is no word perfect for crisis management or security measures. If the car accidentally falls into the water and gets trapped in a closed car and it is difficult to open the door quickly and it takes time to escape, or if the air inside and outside the car is polluted or breathing is difficult due to illness, It is not wasteful to always keep fresh compressed air in a car in case emergency rescue is needed for a person who suddenly has difficulty breathing due to an accident or the like. In particular, storage of compressed air, unlike water, has the advantage of being able to have a very small volume, and is therefore most suitable for vehicles with limited use space. As a safety measure against the above-mentioned disasters, an air hose pulled from a quick auxiliary valve 21 connected to the main air reservoir 4 and the auxiliary air reservoir 6 of the water drop removing door mirror system 1 essential to the present invention to the interior 22 of the vehicle via a pneumatic filter is provided. If you attach a face mask such as an oxygen inhalation mask or aqualung to the tip and keep it in the car,
In the event of an unexpected disaster, it can be taken out and mounted in a fool-proof manner, so that it is possible to obtain an allowance for avoiding a crisis and enable effective first aid treatment.

Since the present invention is constructed as described above, the effect of the water drop removing door mirror system can easily and reliably remove fog and water droplets adhering to the mirror surface of the door mirror and the glass surface of the side window. Since it can be removed, the fore-viewing function and the after-viewing function of the operation effect provided by the movable arm can be sufficiently exhibited without being hindered by fog or water drops when raining or dense fog.

That is, a door mirror system equipped with a water drop removing mechanism is provided. The movable arm has a function of rotating between a retracted position and a return position, and a door mirror is provided by a combined effect of a first door mirror and a second door mirror supported at both ends of the movable arm. As a result of the shooting function and the foreground function, you can grasp the situation in the front and rear direction of the car side and the left and right and up and down direction reliably, so when you pass between other vehicles and buildings on unfamiliar village roads or narrow passages in the city In the case of rainy weather or dense fog, fog and water droplets do not obstruct the view, and the delicate relationship between the car side and the facing object can be reliably foregrounded,
It is possible to prevent a danger of a property damage accident caused by contact or the like. In addition, the visibility of the front, rear, up, down, left, and right of the vehicle is adjusted widely by the mirror driving units of the plurality of mirror bodies, so that driving becomes easy.

There is a problem that fog and water droplets adhere to the door mirror during rainy weather and dense fog, thereby reducing visibility, and that water droplets adhering to the side window near the mirror hinder the visibility of the door mirror seen through the side window. Settle,
Water droplets adhering to the glass surface of the side window can be removed with compressed air that is ejected from the second nozzle of the second air ejection unit provided on one inner surface of the auxiliary movable arm of the movable arm. The safe operation can be performed without obstructing the rear view and the front view by the mirrors of the first and second mirror bodies.

In response to an unexpected disaster, the oxygen auxiliary mask provided in the vehicle is opened by opening the quick auxiliary valve of the water drop removing door mirror system directly from the main air reservoir or the auxiliary air reservoir, or connected to the end of the air hose. Since air can be replenished temporarily by wearing a face mask such as aqua and aqualung, it is possible to obtain a margin for avoiding a crisis and perform an effective emergency treatment.
