Description

Driver's front clock tester

The present invention relates to a test apparatus for a driver's front view for easily determining whether there is a mounting in the vehicle that interferes with the driver's watch.

In order to drive the vehicle safely, the driver's front watch must be sufficiently secured.

It shall comply with the standards in Article 50 (1) 1 through 3 and 6 and 94 of the Safety Standards regulating this.

In this standard, the H coordinates of the V1 and V2 points at the design seat back angle of 25 degrees are 665 mm and 589 mm, respectively, for the tall and short drivers.

In this state, V1 is the lower part of the horizontal plane, the upper part of the plane passing through the point V2 perpendicular to the XZ plane and the front downward 4 ° angle, and the leftward 4 ° angle from the plane passing the V2 point perpendicular to the YZ plane. Place the A-pillar, window support, outdoor radio antenna, rearview mirror, and wiper within the driver's forward field of view, which corresponds to the top of the face and the top of the face perpendicular to the YZ plane and above the plane passing V2. There shall be no obstructions except.

Conventionally, as a method for measuring the presence or absence of obstacles in the driver's front clock, as shown in FIG. 2, a laser beam irradiation apparatus 1 is installed at the V1 point, and a 180 ° section from the left side to the front side to the right side is provided. Irradiation of the laser beam at intervals of 1 ° has been used to test for the presence of obstacles in the area interfering with the laser beam.

However, this conventional front clock measurement process has a problem that the work efficiency is lowered because it takes a lot of time.

The present invention is to solve the above-described problems, it is a technical problem that can be confirmed by projecting the obstacle on the driver's front clock on the screen just by turning on the lamp.

Hereinafter, preferred embodiments and operations of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a perspective view showing the overall structure of the driver's front clock test apparatus according to the present invention.

According to this embodiment, the driver's front clock test apparatus is fixed to the driver's field of view of the driver's seat of the vehicle body, the light emitting means 10 to illuminate the driver's front clock, and the light emitted from the light emitting means interferes the projection It has a structure including a screen 20 to allow the image to be in front of the vehicle.

The light emitting means 10 has guide plates 11 and 12 arranged at predetermined intervals up and down, and mounting holes 13a fixed to the vehicle body at the rear ends of the guide plates and fixed to the rear ends of the guide plates. A fixed frame 13, a lamp 14 fixed to the inner ends of both inner guide plates in contact with the fixed frame, and an on / off switch 15 for controlling the lighting of the lamp. do.

The upper and lower guide plates 11 and 12 are positioned at the maximum eye height and the minimum eye height of the driver, respectively, as test criteria.

The lower guide plate 12 is fixed inclined forward by 4 ° downward with respect to the horizontal plane.

As the lamp 14, a halogen lamp is used.

Referring to Figure 3, the front view test method of the driver according to the present invention having the above-described structure is as follows.

First, the light emitting member 10 is installed inside the vehicle. The screen 20 is installed in front of the vehicle 100.

In this state, the on / off switch 15 is operated to light the lamp 14.

The lit lamp 14 is irradiated with light by the upper and lower guide plates 11 and 12 to the front by an angle corresponding to a certain forward clock of the driver.

Therefore, if there is an attachment to the front field of view, the shadow is projected on the screen so that the obstacle located in the driver's front field of vision can be easily identified.

That is, the present invention does not require a cumbersome process of checking the front view by rotating the beam by a predetermined angle as in the prior art, and can be confirmed as a whole by simply turning on the lamp in front.

With the above-described action, the present invention not only simplifies the test method of the driver's front clock by projecting the shadow of the obstacle that impedes the front clock on the screen with a single operation of turning on the lamp, but also shortens the test time and improves the efficiency and accuracy of the work. It has the effect of raising.
