BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a measuring device for a full test, and more particularly to a measuring device for a full test that accurately and safely measures how far a test vehicle passing a measuring point from an outdoor pool test site deviates from a reference point.

As shown in FIG. 1, the full test site places points A, B, and C on a straight line in which the test vehicle should travel, and displays a little larger than the vehicle width (left and right) at points A and B. The point C is set to 4m in width and the scale is marked every 10cm2 from the center.

In the conventional pull test, between the point A and the point B of the full test site, the driver passes the vehicle width indicator between points A and B while driving the steering wheel, driving the test vehicle in a straight line, and between the points B and C. The driver measured the distance by which the left wheel of the test vehicle which passed the point C from the reference point by driving the test vehicle with the steering wheel high and measured by the human eye.

However, this measurement method has a problem that the data recorded by the measurer is more than ± 10 cm 2 difference, and the measurer must stand for a long time during the test. In addition, this measurement method has a problem that there is a possibility that even personnel accidents occur.

Accordingly, it is an object of the present invention to provide a full test measuring apparatus that can accurately and safely measure a test vehicle when performing a pull test.

An apparatus of the present invention for achieving the above object is a reflection type optical sensor for measuring the distance, a recording device for storing the distance measured at the time and the time measured at the time and the measurement at the reflective optical sensor and digital display; A power supply for supplying power to the fluorescent sensor and the recording device, a case for accommodating and fixing the optical sensor, the recording device and the power supply device, an inner core, an external holder and an adjustment tab to adjust the position of the case. It is characterized in that it comprises a height adjustment mechanism for adjusting up and down, a setting rod installed at the reference point and a tape attached to the test vehicle.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

1 is a schematic diagram of a full test site, FIG. 2 is a schematic configuration diagram of the present invention, and FIGS. 3 (a) to (c) are some detailed views of the present invention.

As shown in FIGS. 1 to 3, the present invention provides a reflective fluorescent sensor 1 for measuring a distance by emitting and receiving light with respect to a tape T attached to a test vehicle, and the reflective optical sensor A recording device (3) for storing the distance measured at (1) and the time at the time of measurement and displaying it digitally, and a power supply (5) for supplying the power required for the reflective optical sensor (1) and the recording device; A case (7) for accommodating and fixing the optical sensor (1), the recording device (3), and the power supply device (5), a pipe-shaped outer holder (9b) and a tooth holder (9b) It consists of a rod-shaped inner core 9a and an adjustment tab 9c which is screwed on the side of the outer holder 9b to fix the inner core 9a whose height is adjusted, thereby raising and lowering the position of the case 7. It includes a height adjustment mechanism (9) to adjust.

Referring to the operation and effects of the present invention configured as described above in detail.

First, the tape T is attached about 1 m horizontally from the left side of the test vehicle. At this time, the tape T to be used is a bright color when the color of the vehicle is dark, but may be anything as long as the measurement sensitivity of the sensor is good.

In addition, after the reflective optical sensor 1, the recording device 3 and the power supply 5 are accommodated in the case 7 and fixed, the adjustment tab 9c of the height adjustment mechanism 9 is used to fix the core. The measuring device is assembled by adjusting the height of the case 7 fixed to 9a with the height of the tape T attached to the test vehicle.

Then, after setting a predetermined reference point at point C of the full test site shown in FIG. 1, a measuring device is installed 3m away from the reference point in a direction perpendicular to the direction in which the test vehicle travels.

Subsequently, when the pull test is started, the test vehicle is driven with the driver holding the steering wheel between the points A and B of the full test site shown in FIG. 1, and the driver has released the steering wheel between the points B and C. Drive the test vehicle at and pass point C. At this time, when the test vehicle passes point C, the measurement distance is 6m and the response speed is 0.01 sec to detect the tape T attached to the test vehicle by the reflective optical sensor 1, thereby detecting the left side of the test vehicle. The wheel measures the distance away from the reference point.

The recording device 3 also stores the distance measured by the reflective optical sensor 1, the full test start time and the test version at the starting point, and displays it digitally.

Then, in order to calibrate the distance of the measured data stored and displayed in the recording device 3, the reference setting bar X is installed vertically at the reference point of the full test site, and then the distance calibration value is measured by the measuring device.

After the completion of the full test, the digitally marked portion of the recording device 3 is visually confirmed, and then the time recorded in the recording device 3 is compared with the time at which the test is closest to each test start time. The measured value is taken as the distance measured value at the start test time.

In addition, as follows,

Actual measurement value: Distance calibration value = 290 cm, version 1 = 225 cm, version 2 = 356 cm

After distance correction:

Version 1 = L65 cm (left wheel 65 cm to the left of the reference point)

Version 2 = R66 cm (left wheel is 66 cm to the right of the reference point)

Convert the distance measurements of each test version to distance calibration.
