Abstract

PURPOSE:To prevent burning of motor by additionally providing a circuit for stopping motor with time limit set to be slightly longer than that necessary for normal opening/closing in a control circuit of driver for flag lamp cover. CONSTITUTION:When functioning a switch 39 to drive motors ML, MR through relay assembly 33 and lamp unit circuits 35, 36 thus to open a cover, a timer circuit T is functioned simultaneously. Upon completion of normal opening of cover, microswitches M1L, M1R will function to turn off the timer circuit T thus to light bulbs 2L, 2R. Upon stopping of motor due to abnormality of cover or gear assembly, the time limit output from the timer circuit T will cause turning off of a transistor Tr through a rectifier SCR having control grid to turn off sub-relays X2L, X2R thus to stop power supply to the motor. It will function similarly when closing the cover.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention enables the cover of a vehicle lighting lamp such as a fog lamp to be opened and closed safely and reliably by remote control from inside the vehicle.
The present invention also relates to a control circuit for a direct-mounted vehicle lamp that automatically opens and closes the cover to turn on and turn off the lamp.

Additionally, vehicle lights such as fog lights that must be turned on while driving are protected from debris, rain, snow, pebbles, etc.
It is preferable to protect the is rfE signal.

Moreover, the lamp cover can be conveniently opened and closed while the vehicle is running from within the city.

Conventionally, as this type of lamp sleep prevention device, there is an example of a cover in which a plastic molded product is removably fitted to the front of the lamp, but this operation is cumbersome as it relies on manual operation. However, if it is necessary to turn on the Mii while the Mii is running, the vehicle must be stopped and the Mii removed from the vehicle without pressing the button, which can be extremely difficult depending on the driving environment, weather, etc.

As a countermeasure for this, if the fog lamp cover is opened/closed and the lamp lights up and blinks once, it is configured to be remotely controlled electrically from the driver's seat.If there is a problem with the cover or if the rotation of the motor for driving the cover to open/close is locked, This may cause unnecessary rotation of the motor or burnout of the motor.

This invention has been made in view of the above points.

The lamp cover takes longer to open and close than usual, and
When the lamp cover is used, the motor drive circuit is turned on by the timer of 1111, and the motor is overheated.

It is an object of the present invention to provide a control circuit for a vehicle lamp with a fully automatic cover opening/closing device that completely prevents consumption of heavy oil due to unnecessary rotation.

Hereinafter, a case where an embodiment of the present invention is applied to a fog lamp will be described based on FIG. 1 to FIG. 14.

It has a 4Φ diameter and can slide in the axial direction (towards the ground in the figure), and the contact with the shaft 15 is in the shape of a cross as shown in Figures 6 (a), (b), and (c). Ribs 13a are formed on the mold. On the other hand, the contact between the shaft 15 and the cam 13 is as shown in FIG. Therefore, even if the output shaft 9a rotates with excessive force applied to the cover 5, the cam 13 will be pushed downward along the axial direction of the output shaft 9a, rotate 90 degrees, and then stop. .

Furthermore, even if the output shaft 9a is fixed and the cover 5 is forcibly opened and closed, the cam 1 will rotate as the shaft 15 rotates.

Next, the operation of the above electric circuit will be explained.

First, to make the explanation easier, timer circuit ■ Part 8- A case will be described in which the output of the Ranjisuf Tr is short-circuited.

When the fog lamp 1 is not used, the cover 5 is closed and the switch SW for lighting one fog lamp is also OFF, so each relay x 1°

The normally open contact of MR-main relay x 1 (-No- is passed through the path of earth E and rotates in the direction of arrow a, that is, in the normal rotation direction, and the cover 5 begins to open. The switches 1V12L and M2R are on the normally open contact C-1'JO side only when the cover 5 is closed.

When the cover 5 finishes opening as the motors ~iL and MR rotate, the first microswitch IV11L is activated.
