[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is suitable for use as a side mirror or the like of an automobile, and more particularly, relates to an outside visual recognition device having a wide field of view and improved visibility and safety.

[0002]

2. Description of the Related Art Conventionally, various proposals have been made for side mirrors and the like of automobiles to effectively and safely capture a rear view. For example, Japanese Utility Model 2-1286
No. 50 discloses a method of projecting the rear field of view condensed by the lens on a concave mirror, and Japanese Patent Publication No. 3-503752 discloses a method of projecting the rear field of view condensed by a prism on a mirror.

[0003]

However, in the above-described method, there is a possibility that the front field of view may be obstructed by a concave mirror or a mirror, which leads to a decrease in visibility. At the same time, the visibility may be obstructed by the pillars of the vehicle, and the visibility may be reduced. In addition, there is a demand for reducing the viewpoint movement of the driver at the time of visually recognizing the rear, thereby improving driving safety, and preventing dazzling due to headlights of a following vehicle. Therefore, an object of the present invention is to provide a vehicle outside visual recognition device that solves the above problem.

[0004]

In order to achieve the above-mentioned object, the invention according to the first aspect of the present invention is directed to a collecting device for collecting rear view light in a body protrudingly arranged on a side of a vehicle. An outside visual recognition device comprising at least light means and mirror means comprising a half mirror for reflecting light condensed by the light condensing means and guiding the light to a driver's eye point. It is possible to increase or decrease the transmittance, and when the light transmittance is set low, the light reflected by the mirror surface means is introduced to the driver's eye point, while the light transmittance is set high. when that is transmitted through the body in front of the light, further
At the driver's eye point through the mirror means
An electrochromic element disposed on the front view side of the mirror means , and a control unit for controlling light transmittance of the electrochromic element by controlling voltage supply to the electrochromic element, and,
A feature is that the mirror surface means is constituted by a half mirror. According to a second aspect of the present invention, there is provided a light collecting means for collecting rear view light in a body arranged to protrude on a vehicle side, and a light collected by the light collecting means. in exterior viewing apparatus at least comprising: a mirror unit for guiding the driver's eye point is reflected, a and a reflecting means for reflecting to a desired site of further front glass rear-view light reflected by said mirror surface means, said Attached to the desired part of the windshield, the light transmittance can be adjusted to increase or decrease, and when the light transmittance is set low, the light reflected by the reflecting means is introduced to the driver's eye point, On the other hand, when the light transmittance is set to be high, an electrochromic element that transmits light incident from the front of the windshield and is introduced into the driver's eye point, and a voltage supply to the electrochromic element are controlled. It allows characterized by comprising control means for controlling the light transmittance of the electrochromic element. According to a third aspect of the present invention, a light condensing means for condensing rear-view light in a body arranged so as to protrude on the side of the vehicle, and the light condensed by the light condensing means is reflected. And a mirror surface means for guiding the driver to the driver's eye point.In a vehicle exterior visual recognition device, at least the light transmittance can be increased or decreased, and when the light transmittance is low, the mirror surface means The reflected light is reflected to a desired portion of the windshield, and the side view light introduced through the side glass of the vehicle is reflected and guided to the driver's eye point, while the light transmittance is increased. The mirror surface means and the driver's eye in order to transmit the light reflected by the mirror surface means and introduce it to the driver's eye point.
The first electrochromic element provided between the point I and the windshield is mounted on a desired portion of the windshield and transmits light forward of the windshield when the light transmittance is set high, while the light transmittance is low. A second electrochromic element that reflects the light reflected by the first electrochromic element again to guide the driver to an eye point when the first and second electrochromic elements are set low; Control means for controlling the light transmittance of each electrochromic element by controlling the voltage supply to the element.

[0005]

According to the above construction, a forward visual field by means of mirror surface means or the like is provided.
In order to prevent the visibility from being lowered, the mirror means is a half mirror, and the mirror means is located behind the mirror means (ie, in front of the vehicle).
Electro controlling the recognition of the forward field of view by changing the transmittance
A chromic element is provided. Then, when you want to see a forward field of view (blind spot field of view by the mirror means), electrochromic
