In FIG. 1, reference numeral 10 indicates a peripheral confirmation device according to an embodiment of the present invention attached to the front door 3 of the vehicle 1.
This peripheral confirmation device 10 is attached to the hinge portion side of the front door 3 of the vehicle body 2, and the mirror 12 (FIG. 3) is mounted on the door mirror housing 11, and the mirror surface of the mirror 12 of the door mirror 13. A camera device 20 composed of a solid-state image sensor such as a CCD, for example, attached to the rear surface 14 of the door mirror housing 11 on the opposite side to the side to monitor the front wheel (not shown) of the vehicle 1 and its peripheral portion. It consists of and. The output side of the camera device 20 is connected to, for example, a video display device 30 (FIG. 1) of a liquid crystal display panel, which is disposed in the vicinity of the driver's seat 7 in the vehicle body 2, and the camera The video shot by the device 20 is displayed.
[0010]
As shown in FIGS. 2 and 3, the camera device 20 is pivotally attached to a lower portion of the front end of the rear face 14 of the door mirror housing 11 of the door mirror 13 as far as possible from the vehicle body 2 side of the door mirror housing 11. It is desirable. The camera device 20 rotatably attached to the storage recess 15 at the lower end of the tip is formed of a solid-state imaging device such as a CCD (Chaege Coupled Device) that converts an optical image incident through the objective lens 21 into an electrical signal. A camera body 22 is provided, and a video signal is sent to the video display device 30 disposed in the driver's seat 7 via a harness (not shown).
The objective lens 21 and the camera body 22 are housed and fixed inside a camera housing 24 via an electronic circuit board / mounting board 23.
[0011]
The camera housing 24 is formed in a cup-like structure along the shape of the housing recess 15 of the door mirror housing 11, and a mounting recess 25 having a hemispherical concave surface on the back surface of the bottom surface and a bottom surface thereof. A through hole 26 penetrating from the central portion to the mounting recess 25 is formed.
On the other hand, a mounting convex portion 16 having a hemispherical convex surface having substantially the same diameter as the hemisphere is formed on the bottom portion of the storage concave portion 15 so as to protrude toward the storage side of the camera device 20, and A funnel-shaped through-hole 17 having a relatively large diameter and having an opening on the convex side is formed in the center. Furthermore, a sliding shaft mounting portion 18 is formed on the back surface of the mounting convex portion 16 and includes a hemispherical concave portion and a cylindrical frame having a substantially cylindrical surface continuous with the inner peripheral surface.
[0012]
The housing 24 for camera storage is attached to the mounting convex portion 16 of the storage concave portion 15 so that the through holes 26 and the through holes 17 coincide with each other, and both from the mirror 12 side. A slide shaft 27 whose head is formed in a spherical shape is inserted into the through holes 17 and 26, and is attached by tightening with a nut 28 from the inside of the camera housing 24 in the mounting recess 25. Thereafter, the camera body 22 and the electronic circuit board / mounting board 23 are fixed in the camera housing 24 and the front opening of the camera housing 24 is closed with the transparent cover 29. The outer peripheral surface of the sliding shaft mounting portion 18 is tightened by a ring-shaped spring 19. With such a structure, the periphery confirmation apparatus 10 according to the embodiment of the present invention is configured.

As shown by the arrows in FIG. If a transmission device for transmitting the power of an electric motor (not shown) is connected to the rotation structure of the camera device 20, the driver P can control the rotation angle of the camera device 20 from the driver seat 7. .
[0014]
Accordingly, the driver P controls the camera device 20 and, if necessary, turns the camera device 20 obliquely forward and downward to confirm the situation of the front wheel of the vehicle 1 and its surroundings. The scene in the forward direction can be confirmed from moment to moment, and the field of view of the vehicle 1 can be widened as shown by the hatched line A in FIG.
Furthermore, normally, the door mirror 13 itself can be electrically controlled from the driver's seat 7 and can control not only the left and right opening / closing angles but also the elevation angle. It is possible to confirm the situation immediately below the door mirror 13 attached.
[0015]
In the above embodiment, the peripheral confirmation device 10 that can confirm (monitor) the blind spot of the right-hand drive vehicle 1, particularly directly under the left fender, has been illustrated and described. In addition, since the peripheral portion thereof is also a blind spot, it goes without saying that the peripheral confirmation device of the present invention can also be applied to the right side door mirror 13 of the vehicle 1. Further, it should be noted that the peripheral confirmation device of the present invention can be similarly applied to a left-hand drive vehicle.
