Description

  The present invention is a so-called room mirror, which is installed in a vehicle such as an automobile, and relates to an in-vehicle rear-view mirror for checking the rear of the vehicle. In particular, the present invention can be used as a rear-view mirror for checking the rear. The present invention also relates to an in-vehicle endoscope that can also visually recognize the front through the in-vehicle endoscope.

  Currently, many of the rearview mirrors that are standard equipment in automobiles are relatively small, and in order to widen the field of view for rearward confirmation, a so-called wide mirror, a large-sized rear-view mirror, is attached as a retrofit. Is the current situation.

  However, when the wide mirror as described above is mounted on, for example, an automobile, the front view is hindered due to its large size.

  In other words, if a wide mirror is attached, the right-hand drive vehicle will cause a traffic accident when the left-hand drive vehicle turns left and the left-hand drive vehicle turns right, which may cause a traffic accident. This is particularly noticeable when driving on a curved road or the like. Also, when the right-hand drive vehicle stops on the right turn lane, and when the left-hand drive vehicle stops on the left turn lane, it becomes difficult to check the traffic light, so it is delayed to notice that the signal has changed, and as a result, the start is delayed. May cause traffic disturbance such as traffic jams. Furthermore, since signs such as road signs become difficult to see while traveling, grasping the contents may be delayed, which may cause dangerous driving and traffic accidents. In addition, since a blind spot can be formed forward by the wide mirror, when there is a jump out in front of the car, the response may be delayed, leading to an accident.

  One example of the above problem will be described in detail with reference to FIG. A in the figure is a right-hand drive passenger car, which is equipped with a commercially available wide mirror. A region B in the figure is a blind spot region as viewed from the driver who is on the passenger car A. When the wide mirror is mounted in this way, the driver's eye looking left front and the wide mirror overlap with each other to form a wide blind area B. In the figure, when the signal of the traveling direction of the passenger car A is blue, and the passenger car A is going to turn left, if the pedestrian C crossing the pedestrian crossing enters the blind spot area B, the driver of the passenger car A moves the upper body forward. You must check out and check your safety by sticking out your face. In addition, D in the figure is a large vehicle such as a truck and is stopped in the opposite lane on the left front of the intersection. When the pedestrian signal changes from blue to flashing, the large vehicle D stops. It is often seen that the bicycle E jumps out of the sidewalk along the oblique line, suddenly turns right, and tries to pass through the pedestrian crossing at high speed. In such a case, it is difficult for the driver who is riding the passenger car A to find the bicycle E that jumps into the blind spot area B at a high speed, and the passenger car A is also trying to make a left turn, which is very dangerous. . The present invention eliminates such a dangerous state and enhances traffic safety. Even when a wide mirror is used for rearward confirmation, a blind spot is eliminated by using the wide mirror as a half mirror. So that the front can be confirmed.

  In some cases, a so-called half mirror is used that reflects the light incident on one surface and transmits the light incident from the other surface to the room mirror. A built-in CCD camera that allows the inside of the vehicle to be photographed by the CCD camera, and a liquid crystal display device that displays information such as time and various signals inside the interior of the rearview mirror housing. All of them are designed to function the device built in the housing of the rearview mirror by utilizing the light transmittance of the half mirror. Therefore, by using a half mirror for the room mirror, there is no idea of ensuring safety by expanding the forward field of view and thereby enabling the driver to easily confirm the front.

  In view of the above circumstances, the present invention provides an in-vehicle rear-view mirror that can be used as a rear-view rear-view mirror and can also be viewed in front through the in-vehicle rear-view mirror, thereby improving vehicle safety. The purpose is to contribute.

  An in-vehicle endoscope according to the present invention is provided in a vehicle such as an automobile, and is an in-vehicle rear mirror for confirming the rear of the vehicle, and a part or all of the in-vehicle endoscope is a light transmission plate. The light transmission plate reflects a part of incident light irradiated on the in-vehicle rear-view mirror from the rear of the vehicle, and is incident on the in-vehicle rear-view mirror from the front of the vehicle. It is characterized in that a part of the light is transmitted.

  With this configuration, the light transmission plate that occupies a part or all of the in-vehicle rear-view mirror reflects a part of incident light irradiated to the in-vehicle rear-view mirror from the rear of the vehicle. The rear can be confirmed by the transmission plate. In addition, since a part of the incident light irradiated to the in-vehicle rear-view endoscope from the front of the vehicle passes through the light transmission plate, the light transmission plate can be used to visually recognize the front. Therefore, the in-vehicle rear endoscope according to the present invention allows not only the rear confirmation but also the front visual recognition, and does not prevent the front visual recognition or cause a blind spot unlike the conventional in-vehicle rear endoscope. As a result, the safety of vehicle travel is greatly improved.

  In the in-vehicle rear-view endoscope, the light transmittance of the light transmission plate may be in the range of 0.1% to 90%, and more preferably, the light transmittance of the light transmission plate is in the range of 3% to 55%. Also good.

  If comprised in this way, it will become more suitable to fulfill | perform the function of both back confirmation property and forward visibility. The light transmittance is measured by “TINT METER INSPECTOR / MODEL200” manufactured by Laser Laboratories, USA.

  Furthermore, in the in-vehicle rear endoscope, the light transmittance of the light transmission plate may be partially different.

  With this configuration, in addition to having forward visibility and backward confirmability, the light transmittance is lowered and the reflectance of incident light from the rear is increased to give priority to backward confirmability, and the light transmittance is increased. Thus, it is possible to select a part that prioritizes forward visibility, and it is convenient because it can be selectively used according to the situation.

  Moreover, in the above-mentioned in-vehicle endoscope, the in-vehicle endoscope may be provided integrally on the upper part of the windshield.

  With this configuration, it is possible to eliminate the conventional suspension-type in-car endoscope, and there is no visual obstacle to widen the field of view, and there is no physical obstacle to the suspension-type in-car endoscope. No more bumping your head.

  As described above, the in-vehicle rear endoscope according to the present invention can be used as a rear-viewing rear-view mirror, and can also be viewed in front through the in-vehicle rear endoscope. It is to improve.

  Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
