Description

[Detailed Description of the Invention] This invention is a fully automatic system that allows you to safely and reliably open the cover of a vehicle lighting lamp, such as a fog lamp, by remote control from inside the vehicle, and that turns on and off the lamp in conjunction with the opening and closing of the cover. The present invention relates to a control circuit for a dual-use light fixture with a cover opening/closing device.

Generally, for vehicle lights such as fog lamps that need to be turned on while the vehicle is running, it is preferable to protect the front lens from debris, rain, snow, pebbles, and the like.

Moreover, it is convenient that the lamp cover can be opened and closed from inside the vehicle while the vehicle is running.

Conventionally, as this divine lamp protection device, there is an example of a cover in which a glass material made of Narusugi is removably fitted to the front of the light fixture. It is cumbersome to operate because of the F1, and if you feel safe to turn on the light while driving, then stop the train at σI1 (you have to stop the operation, and depending on the driving border or the weather, etc.) has drawbacks that make this task extremely difficult.

Further, as a control circuit for a vehicle lamp equipped with an automatic cover opening/closing device, there is no known control circuit that can safely and reliably control the opening/closing of the cover and the lighting of the lamp with a simple circuit configuration and a lamp switch after one circuit.

This invention was made in view of the above points.

Two microswitches (four actual output elements) that detect both rotational end positions of the output shaft of the motor gear assembly for opening and closing the fog lamp cover, and a short circuit and voltage application between both terminals of the motor for driving the cover. A sub-relay circuit for switching the state and a main relay circuit for rotating the motor in the forward and reverse directions are provided, and the main relay circuit is driven through a light switch, and the contact of one of the microswitches and the contact of the light switch are provided. By configuring the lamp bulb to flash through the part line circuit, the F111 switch of C1 structure allows you to safely open and close the fog lamp cover and flash the lamp from inside the vehicle. The object of the present invention is to provide a control circuit for a vehicle lamp equipped with a total of 11 power bar opening/closing devices.

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

Figures 1 to 4 show the exterior and part of the interior of the fog lamp 1 with a cover, in which 2 is a bulb such as a halogen light bulb, 3 is a housing, and 4 is when the fog lamp 1 is attached to the vehicle body (not shown). 5 is a bracket for attaching the fog lamp 1 to the front position IM (indicated by a solid line) and an upper position (indicated by a two-dot chain line) to open and close the cover 7.

) If excessive force is applied to the cover 5 when opening or closing the cover 5,
Output 11111+ 9a and 15゛j can be rotated regardless of output. That is, the cam 13 has a hole with a D cut, and the cam 13 is inserted into the output shaft 9a of the same shape, and the cam 13 is inserted into the output shaft 9a of the same shape.
It can be seen that sliding is possible in the vertical direction (in the figure), and the contact surface with the shaft 15 is
As shown in c), the lip 13a is formed in a cross shape. On the other hand, the contact surface of the shaft 15 with the cam 13 is shown in FIG.

Therefore, even if the output shaft 9a rotates while an excessive force is applied to the cover 5, the cam 13 is pushed downward along the axial direction of the output shaft 9a, rotates 90 degrees, and then stops. Furthermore, even when the output shaft 9a is fixed and the cover 5 is forcibly opened and closed, the cam 13 is pushed downward in the figure along the axial direction of the output shaft 9a as the shaft 15 rotates, and the cam 13 rotates 900 times. Now, cam 13 and shaft 1
The engagement with 5 returns to its original state. In either case, the push-up blade of the Shizuru coil spring 14 works sufficiently, and the cam 13
The shape of the shaft 15 prevents the cover 5 from stopping midway.

The rotary shaft hole 5c on the opposite side of the guide bar 5 is connected to the round boss 1 of the housing 3 through a special washer 16 (Fig. 3).
It is inserted in 7. Further, the lamp unit 7 is waterproofed by a seal casket 18 (Fig. A1), and the first hole in the output shaft 9a is waterproofed by a seal gasket 19 (Fig. 5).

The motor gear assembly 9 is housed in the housing 3 of the left and right fog lamps 1, and its details will be explained with reference to FIGS. 8 to 11.

The gear case 20 and the side cover 21 that fit into the gear case 20 form a container 114. The output III 19a protrudes outward from the side cover 211, while the gear plate 2 is located inside the container.

1111i (side cover 21 at), a pinion gear 23 is fixed to the motor 111fVla, which protrudes from the motor M which is fixed to the opposite side (gear case 201111), and the gear plate 22 has a pinion gear 23 arranged in the pulp chamber i'X. The rotation of the motor M is transmitted to the C1-type output gear 27 at a reduced speed through the coupling gears 24, 25, and 26i.

The output shaft 9a, which is the shaft of the output gear 27, is connected to the cover 5 through the aforementioned coupling mechanism, that is, the clutch rock 4 structure 10.
It can be connected to the shaft 15 (Fig. 5) of.

As shown in FIGS. 9 and 10, the gear case side of the gear plate 22 includes a motor M and a second microswitch 29. whose operating directions are perpendicular to each other. A cam 30 fixed to the output shaft 9a. A wiring cord 31 connecting the microswitches 28, 29, the motor M, and the outside is housed therein, and is connected to the outside via a cable 32.

At the position k of the cam 30 in Fig. 1O (indicated by the actual win), water is diverted with the cover 5 closed, and the tip of the cam 30 turns on the micro switch 28 of 14 (2), and the first micro switch 29 turns on.

As described above, this invention is configured so that all operating sounds such as opening and closing of the fog lamp cover and blinking of the pulp of the lamp can be controlled by a single circuit switch on the driver's seat. The switch and wiring can be used as is.

Also, since the cover drive motor is configured to short-circuit its terminals when it stops, the motor stops instantly and the cover stops accurately at the open/close position.

No stress is placed on the rotating parts due to rotation clearance, etc.

There are other effects.
