JPS597241A - Head light tester device - Google Patents

Abstract

PURPOSE:To eliminate the inconvenience by the disconnection of a cable by transmitting and receiving wirelessly operation signals and measurement data signals between a head light tester body and an operation display device. CONSTITUTION:Measurement is accomplished by operating an operation part 5a to transmit wirelessly an operation signal from a transmitter 5b, receiving the same in a receiver 3e, and running motors 6a, 6b with a control device 3f to move a head light tester 3 until the tester is located in front of an automobile and to move a photodetection part 3e vertically so that said part is located in the position facing to the head light. The luminous intensity, optical axis, etc. of the head light are measured with a photodetecting sensor 3g, and are subjected to data processing with a data processor 3h, the data whereof are transmitted wirelessly by a transmitter 3i. The transmitted data are received by a receiver 5c and are displayed on a display part 5d. The tester body 3 is returned to the standby position in proximity to a power source device 4 upon ending of the test and a charger 7 is charged.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a headlight tester device used for automobile maintenance inspections, etc.

As a conventional headlight tester device, a rail is laid on the floor, a headlight tester body is movably mounted on the rail, and a stationary stand installed near one end of the rail and the tester body are connected. It is known that the tester is connected by a cable such as a power source, but according to this conventional device, the cable is either stretched or sagging every time the tester main body moves back and forth on the rail. The cable repeatedly bends and stretches, and eventually breaks, making it unusable as a headlight tester.

It is an object of the present invention to provide a headlight tester device that eliminates such inconveniences, and includes a power supply device and an operation display device provided at one end of the rail, and a power supply device and an operation display device are provided at one end of the rail, and the tester body and operation display device are connected to each other. A transmitting device and a receiving device are provided in the transmitting device, and between the transmitting device and the receiving device, an operation signal is transmitted from the operation display device to the tester body, and a measurement data signal is transmitted from the tester body to the operation display device. Wireless transmission and reception is performed, and a charging device is further provided in the tester main body, and the charging device is charged via a detachable connector when the tester main body is close to the power supply device. shall be.

An embodiment of the present invention will be described below with reference to the drawings.

(1) is a floor surface, and (2) is a rail laid on the floor surface (1).

+s) i, j: Shows a headlight tester main body moving on the rail (2), the tester main body (8) has a base (3a) having running wheels and a support (3b) erected thereon.
It consists of a light receiving section (3C) provided to move vertically thereon, and a box (3d) provided at the lower end of the support column (3b).

(4) is a power supply device provided at one end of the rail (2).

(5) indicates an operation display device provided above the power supply device (4), and the operation display device (5) includes an operation section (5E1.).
a transmitter (5b) that transmits future operation signals; a receiver (5c) that receives measurement data signals from a transmitter (31) to be described later; and a display section or box (3d) that displays the measurement data. Inside is a receiver (3e) for receiving the operation signal, a motor (6a) for decoding the operation signal and moving the headlight tester main body (8), and a light receiving part (3C) for moving the headlight tester body (8) up and down. Motor to move (6
b) a control device (3f) that controls the rotation; a data processing device (3h) that processes the detection signal from the light receiving sensor (3g) provided in the light receiving section (3c); and the processing device (3h). Transmitter that transmits measurement data (31)
Equipped with:

(7) is the receiver (3e), the control device (3f),
A charging device that supplies electricity to a data processing device (3h), a transmitter (31), etc. is shown, and the charging device (7) is connected to the base (
3a) is provided at the rear end of the tester body (
8) is charged via the detachable connector (8) when the battery comes close to the power supply device (4).

Thus, when the headlight tester body (3) is in a standby state near the power supply device (4) as shown by the dotted line in FIG. 1, the connector (8) is connected and the charging device (7) is charged. Ru.

The next time you take a measurement, fully operate the operation section (5a) and use the transmitter (
The operation signal is transmitted wirelessly from 5b) and is received by the receiver (3e).
Receive and control rack! (3f) Motor from K (6a)
and (6b) to move the headlight tester (8) to position it in front of the vehicle as shown by the solid line in FIG. Let it be. At this time, the connector (8) is in a separated state. And the light receiving sensor (3g
) measures the luminous intensity, optical axis, etc. of the headlights, processes the results with the data processing device (3h), transmits the measured data wirelessly with the transmitter (31), and transmits it with the receiver (5c). It is received and displayed on the display section (5d).

After the measurement is completed, the headlight tester main body (3) is returned to the standby position close to the power supply device (4) and the charging device (7) is charged. Measurement is performed by repeating the above steps.

As described above, according to the present invention, a transmitter and a receiver are respectively provided in the moving headlight tester main body and the stationary operation display device, and the operation signal and measurement data signal are exchanged wirelessly between the two. The headlight tester is equipped with a charging device so that the charging device is charged from the power supply device when it is in standby mode, eliminating the need for a cable, which eliminates the need for a cable that would cause the headlight tester to become unusable, unlike conventional devices. Furthermore, since there are no obstacles such as cables, it is easier to work around the headlight tester.
