Abstract

PURPOSE:To keep the area around the front wheel and the rear wheel visual from the driver's seat by retractably mounting a cover having a mirror inside thereof to a recess formed in the front side of the body and protruding the cover in a predetermined amount at a predetermined angle as required. CONSTITUTION:A body 1 has a recess 2, and a cover 3 to be fitted in the recess 2. The cover 3 has a mirror 4 attached to the inside thereof and connected to the bottom wall of the recess 2 by two links 5, 6. There are provided springs 7, 8 for urging the links 5, 6 toward the inside of the recess 2, and a wire 9 is connected to one link 5 to shift the cover 3 by pushing and pulling of the wire 9. Thus constructed, the wire 9 is pulled, as required, to rise the links 5, 6 and thereby to protrude the cover 3 out of the body 1 in a predetermined amount at a predetermined angle, so that the driver can have a view of the area around the front wheel 12 and the rear wheel 13 from the driver's seat.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is directed to eliminating lateral blind spots in a front bonnet type automobile by making it possible to easily see the areas around the ground contact areas of the front wheels and rear wheels from the driver's seat. Regarding equipment.

[Conventional technology]

Conventionally, automobiles are equipped with rearview mirrors for visually checking the rear, but except for buses and large trucks, it is not possible to visually see the front part of the vehicle body and the area around the front wheels.

This often leads to extremely dangerous situations such as collisions when leaving or parking in narrow spaces, or vehicles running off the road into ditches. Countermeasures against these problems are one of the most important factors in automobile traffic, which has been increasing rapidly in recent years. This was one big problem.

As a countermeasure against this problem, one effective means is to place a dedicated mirror on the front side of the car body so that the wheels on the opposite side of the driver's seat can be visually seen, separate from the mirror for checking the rear. Some ordinary cars, such as cars, have a configuration in which a convex mirror is fixed in a predetermined position.

[Problem that the invention seeks to solve]

However, when placing such a dedicated fixed mirror,
The reflective area for the driver's seat is limited, and depending on the driver's posture, vehicle width, and mirror mounting position, it may not be possible to obtain the necessary viewing area.Furthermore, a wide-angle short-focus convex mirror is used to reflect a wide area with a fixed mirror. However, this method causes image distortion and extreme differences in image size due to distance differences, so there is a problem that it is insufficient for actual use.

An object of the present invention is to make it possible to reliably visualize the area around the front and rear wheels even if the size of the vehicle body, the posture of the driver, etc. change variously.

[Means for solving problems]

The present invention provides a recess for storing a mirror provided on the side of a front bonnet of an automobile, a cover that can be opened and closed to cover the opening of the recess, a mirror attached to the inner surface of the cover, and a method for adjusting the opening of the cover. Therefore, by adopting a configuration including a mirror angle adjustment mechanism that adjusts the reflection area of the mirror as seen from the driver's seat to be near the sides of the front wheels and rear wheels, the driver's posture changes. Even if the driver changes, the mirror can be adjusted so that the reflected image is reflected at the optimal position near the front wheels.

〔Example〕

The present invention will be described below based on embodiments shown in the drawings.

FIG. 1 is a perspective view of an automobile equipped with a side blind spot eliminating device according to the present invention, FIG. 2 is a sectional view of the device, and FIG. 3 is a sectional view of the device with the cover open.

The lateral blind spot elimination device is placed on the side of the hood opposite to the driver's seat, and a recess 2 is formed in the vehicle body 1, and the opening area of the recess 2 is aligned with the surface of the vehicle body 1 to create an integrated appearance. It is equipped with a cover 3 that exhibits

A mirror 4 is attached to the inner surface of this cover 3 and is connected to the bottom wall within the recess 2 by two rod-shaped or plate-shaped links 5.6.

This link 5.6 essentially constitutes a four-bar parallel link and allows the cover 3 to be shifted out of the vehicle body 1 as shown in FIG.

Link pins 5a and 6a for pivotally connecting the links 5.6 to the vehicle body 1 and the cover 3 are connected to the vehicle body 1 as shown in FIG.
The configuration is such that the positional relationship is relative to . That is, in FIG. 4, if AB indicates the direction of the axle, BC indicates the longitudinal direction of the vehicle body, and AD indicates the vertical direction, then the axial direction of the link pins 5a and 6a is represented by the line segment DF.

In such arrangement of the link pins 5a, 6a, if the angle α between the straight line drawn from the driver's seat toward the reflective surface of the mirror 4 shown in FIG. 1 and the axle axis direction is 50 degrees, the fourth
Preferably, the angles β and T in the figure are approximately 40 degrees and 13 degrees, respectively. However, the values of these angles β and T vary slightly depending on the focal length and shape of the mirror 4, and are determined by a certain relationship with the value of the angle α, which is affected by the width of the vehicle. .

The drive mechanism for shifting the cover 3 can be any of a variety of conventionally used mechanisms, and in this embodiment, a spring 7 that biases each link 5.
．． 8 respectively, and wire 9 to one link 5.
This is done by connecting the wires 9 and pushing and pulling the wires 9.

The wire 9 can be driven by connecting an electric motor to the output shaft of an electric motor arranged inside the vehicle body 1 and operating it by rotating it in forward and reverse directions, or by placing a knob in the driver's seat and turning it in and out. In this case, the configuration is such that the amount of expansion and contraction of the wire 9 can be freely changed from the driver's seat, and the relative angle of the cover 3 to the vehicle body 1 can be set arbitrarily.

Note that 10.11 is a rearview mirror for checking the rear.

In the side blind spot eliminating device having the above configuration, during normal driving, the cover 3 is closed and integrated with the vehicle body 1 as shown in Fig. 2, and when the need arises, the wire 9 is connected by a drive mechanism. Pull it up to raise the links 5 and 6 as shown in Figure 3, extend the cover 3 to the outside of the vehicle body, and displace it so that the driver can visually see the area around the front wheels 12 and rear wheels 13 from the driver's seat M. .

At this time, the amount of tightening of the wire 9 can be arbitrarily changed by the amount of rotation of the electric motor output shaft or the amount of pull of the knob in the case of a manual type, so the amount of displacement of the cover 3 and the relative angle with respect to the vehicle body l can be arbitrarily set. can.

This shift of the cover 3 moves the link pins 5a and 6a to the fourth position.
By arranging the vehicle body 1 as shown in the figure, the fifth
As shown in the figure, the reflective area for the driver's seat M can be changed from the front wheels 12 to the periphery of the rear wheels 13 depending on the opening angle of the cover 3.

As described above, since the displacement of the cover 3 can be set arbitrarily, it can be set at a position that is easy to see regardless of the size of the vehicle body 1 or the driver's posture, so parts that cannot be seen from the driver's seat M can be easily checked visually. Accidents can be prevented.

〔Effect of the invention〕

The lateral blind spot eliminating device for an automobile according to the present invention has the following effects due to its configuration.

(11) Since you can easily visually check the area around the front wheels that cannot be seen from the driver's seat, you can safely evacuate to the roadside when leaving the vehicle or pull over when parking.

(2) Since the amount of displacement of the cover to which the mirror is attached can be set arbitrarily, a reliable field of view can be obtained regardless of the size of the vehicle body or the driver's posture.
