JP3024056U - Compressed air injection type water drop elimination rearview mirror - Google Patents

Abstract

(57) 【Abstract】 PROBLEM TO BE SOLVED: Current rear-view mirrors for automobiles have a poor visibility and are dangerous to the driver because water droplets adhere to the mirror surfaces when driving in the rain. Furthermore, in the case of rainy night, the mirror does not act its function because the water droplets attached to the mirror are reflected by the irradiation of lights from the following vehicles. In particular, when running for a long time on a highway or the like during heavy rain, commercially available water drop removing articles are meaningless and ineffective, and the risk of being directly connected to a traffic accident is extremely high. Therefore, safety measures against these are required. The present invention eliminates water droplets from a mirror by blowing compressed air from around the mirror in order to eliminate the risk of vehicle operation caused by water droplets adhering to the mirror surface. The exclusion time is adapted to the time of rain.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to elimination of water droplets attached to an automobile rearview mirror due to rain or the like, and more particularly to a compression air jet body, a mirror holding frame, and a mirror support.

[0002]

[Prior art]

 Heretofore, as a technique of this kind, a spray-type clean view, which is an oil film eliminating product on the surface of the windshield, has been used for removing water droplets.

[0003]

[Problems to be solved by the device]

 As is well known to drivers, mirrors are used in automobile rearview mirrors. Therefore, when water droplets due to rain or the like adhere to the mirror due to surface tension during or at the start of traveling, the visibility in operation is poor, and especially during night driving, the water droplets may adhere to the surface. It is illuminated by the light of the following vehicles and reflected, and the visibility is almost zero. It is no exaggeration to say that the driver's psychology in such a situation is that most of them rely on their feelings. However, operating a vehicle in such a situation is extremely dangerous, and there is a great risk of being directly connected to an accident. As described in the prior art, as a water drop removing article for a rearview mirror, various kinds of articles for removing an oil film on the windshield surface have been conventionally used. This is due to the oil film effect produced by the action. However, it is instantaneous and unsustainable because the water droplets caused by rain wash off the oil film on the mirror surface. In particular, the function of the back mirror does not work at all during long night driving on expressways during heavy rain. Therefore, the possibility of traffic accidents due to such poor visibility is extremely high, and safety measures against this point are urgently required from the viewpoint of accident prevention.

[0004]

[Means for Solving the Problems] In order to achieve the above-mentioned object, a compression air jet type water drop elimination rearview mirror of the present invention is provided with a compression air ejection body having a hollow interior inside a mirror pressing frame. It will be a newcomer.

At the inner side of the compression air jet body, the edge on the so-called mirror side, there is a projection tube with small holes in the horizontal direction, so-called compression air jet port, so that compressed air is jetted over the entire mirror. It is provided.

Further, the compression air ejection ports located on the left and right of the mirror are directed obliquely downward so as to prevent the inflow of water droplets adhering to the mirror and to easily remove them. Further, the edge line is adapted to coincide with the edge line on the so-called mirror side inside the mirror holding frame.

Further, both ends of the compression air jetting body are closed at appropriate positions so as to prevent a pressure drop due to the loss of the compression air.

Furthermore, a hole for introducing the compression air for connecting to the compression air introducing pipe is formed in the center of the central portion on the opposite side of the compression air ejecting port, the so-called compression air ejecting body.

The mirror pressing frame main body has a structure in which the mirror is fixed, and the end side of the mirror pressing frame is a so-called mirror pressing frame in which the compression air jet body is installed.

[0010]

[Embodiment of device]

 Embodiments of the invention will be described with reference to the drawings. As shown in FIG. 1, the compressed air jets 3 are arranged inside the mirror holding frame 1 around the mirror.

As shown in FIG. 1, the upper side of the mirror 4 upper side of the so-called compression air ejection port 2 is arranged so as to be attached to the surface of the mirror 4 so that the water droplets are swept away from above by the compression air, and The structure of the compression air ejection port 2 is as shown in FIGS. 2 and 3 in order to strengthen it and prevent the inflow of water droplets.

Left and right parts of the mirror 4 The so-called left and right parts of the compression air ejection port 2 are arranged so as to be attached to the mirror 4 and push water droplets obliquely downward from the upper side, as shown in the left side part of FIG. In addition, in order to strengthen it and prevent the inflow of water droplets, the structure of the jet outlet is as shown in FIGS. 2 and 3.

The central hole on the opposite side of the compression air outlet 2 is a so-called compression air inlet 7, one end of which is connected to a vehicle-mounted compressor, and one of which corresponds to the left and right rearview mirrors, so that it is separated into two on the way. Is connected to one end of the compressed air introduction pipe.

As shown in the left side portion of FIG. 1, both ends of the compressed air jet body 3 are closed in order to prevent the pressure from decreasing due to the loss of compressed air.

The inside of the mirror column 6 is hollow because the compressed air introduction tube is inserted therein.

[0016]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

When the switch is turned on, the vehicle-mounted compressor operates. The compressed air generated by the operation is continuously jetted from the compressed air jet through the connected compressed air introduction pipe and the compressed air jet. As a result, surface tension acting on the mirror such as water droplets attached to the mirror surface is destroyed, and water droplets and the like are removed from the so-called rearview mirror.

Due to the above-mentioned effects, in rainy weather, it is not necessary for the vehicle driver to get out of the vehicle and adhere to the back mill to use a water drop removing article such as clean view to remove water drops. In particular, there is an advantage that it can be used depending on the time of rain.

Furthermore, the poor visibility of the vehicle driver to the rearview mirror in rainy weather is eliminated, and the risk of occurrence of a traffic accident due to the poor visibility is eliminated.

In the above case, the water droplets adhering to the surface of the rearview mirror at night are actually reflected by the light of the following vehicle or the like and do not fulfill the function of the rearview mirror at all. By eliminating this functional failure, the safety of vehicle operation is enhanced. The effect is particularly great when driving a vehicle for a long time, such as on an expressway.

Since the compression air injection port and the inner edge line of the mirror pressing frame are set to coincide with each other, the appearance is not impaired.

Since the structure of the compression air jet port is as described above, the jet pressure of the compressed air is strengthened, so that the water droplet removing action is strengthened. It also prevents the inflow of water droplets.
