Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is used as a headlight of a vehicle, particularly an automobile,
The present invention relates to a lamp capable of laterally irradiating a part of light.

[Conventional technology]

Conventionally, this type of lamp has been equipped with a sub-reflector for irradiating a part of light laterally, and the lower part of this sub-reflector is rotatably supported around the lower part of the bulb erected from the bottom side of the lamp chamber. And the upper part is connected to the driving means through a pin that passes through the upper plane part of the reflector and is arranged on the front surface of the reflector, and the driving means causes the sub-reflector to rotate the central axis of the valve along the front surface of the reflector. There is a structure that is provided so that it can be moved, and the sub-reflector is moved by the operation of the drive means according to the handling when a vehicle approaches a curve while traveling, and a part of the light is emitted in the turning direction. I am able to do it. In order to return the sub-reflector to the center of the lamp, that is, so that the light from the sub-reflector moves in the normal irradiation direction, it is fixed to the pin that locks to any fixed part in the lamp chamber and the sub-reflector side. The pin that rotates together with the sub reflector is connected by a spring, and the sub reflector returns to the center of the lamp by pulling the spring.

[Problems to be solved by the device]

However, in the above-mentioned conventional structure, the sub-reflector is attached so as to be rotatable with respect to the metal socket holder supporting the valve, and the socket holder supports the sub-reflector. There is a problem that the rotation of the sub is not performed smoothly, and as a structure for returning the sub-reflector to the center, a pair of pins and a spring that connects the pins are required as described above, and thus the number of parts is increased. That is, there is a problem that the lamp assembling work is complicated. Therefore, it has been a problem to develop a lamp which can smoothly respond to the operation of the driving means and has a simple structure.

[Means for solving the problem]

The present invention has been made in consideration of the above-mentioned conventional problems, and the lower part is rotatably supported around the lower part of the bulb standing upright from the bottom of the lamp chamber, and the upper part is a pin for inserting the upper flat part of the reflector. A sub-reflector connected to a driving means via a front surface of the reflector is provided, and in a lamp in which the sub-reflector is rotatably movable by the driving means, a bulb is supported below the reflector and the sub-reflector. A circular hole corresponding to the socket holder is provided, and the peripheral edge of the circular hole of the sub-reflector and the peripheral edge of the circular hole of the reflector are slidably contactable via a resin ring so as to correspond to each other. The lower part is rotatably connected to the lower flat part of the reflector, and the pin of the upper flat part of the reflector is inserted. A drainer formed by bending the periphery of the insertion hole upward is provided on the peripheral edge of the insertion hole, and a pair of spring members abutting on the upper portion of the pin in a biased state with their tips open to the fixed portion in the lamp chamber. The present invention provides a vehicular lamp characterized by being provided with one biasing member consisting of

〔Example〕

Next, the present invention will be described in detail based on an embodiment shown in FIGS. 1 to 3.

In the drawing, reference numeral 1 denotes a vehicular lamp according to the present invention. In a lamp chamber of the lamp 1, a bulb 2 is arranged upright from the bottom side of the lamp chamber, and a front surface of a reflector 3 is
A sub-reflector 4 is arranged, and a driving means 5 for moving the sub-reflector 4 is arranged in a space formed by the reflector 3 and the housing 6 at the corner of the lamp chamber.

A circular hole 8 is opened in the lower portion of the sub reflector 4 so as to correspond to the socket holder 7 supporting the bulb 2. Then, like the circular hole 8, a circular hole 10 is opened in the lower flat surface portion 9 of the lifter 3 corresponding to the socket holder 7,
A resin ring 11 is provided on the upper peripheral edge of the circular hole 10,
The peripheral edge of the circular hole 8 of the sub reflector 4 is slidably attached to the resin ring 11 so that the sub reflector 4 is rotatably supported by the resin ring 11. In addition, the reflector 3 is provided above the sub-reflector 4.
A pin 14 for inserting an insertion hole 13 located on the center line of the bulb 2 in the upper flat surface portion 12 is provided, and the upper portion of the sub-reflector 4 is supported by the reflector 3 via this pin 14, and the sub-reflector 4 is The bulb 2 can be rotated and moved in front of the reflector 3 with the center line of the bulb 2 as the center of rotation.

On the upper flat surface portion 12, an arm 15 from the driving means 5 is connected to a pin 14 protruding from the insertion hole 13 in a state of being eccentric with respect to the pin, and the rotational driving of the driving means 5 drives the arm 15. The pin 14 is rotated by the moving arm 15 so that the sub-reflector 4 is rotated, and the movement of the sub-reflector 4 is controlled by driving the driving means 5.

The peripheral edge of the insertion hole 13 through which the pin 14 is inserted is bent upward, and a drainer 16 is provided to improve the state of sliding contact with the pin 14 and prevent water from entering.

The pin 14 is provided with one biasing member 17 composed of a pair of spring members whose tips are in contact with each other in a state of opening toward the front edge folded back 12a of the upper flat surface portion 12 which is a fixed portion in the lamp chamber. The spring members of the biasing member 17 are in contact with each other in the biased state by the same drag force. When the sub-reflector 4 rotates by a predetermined angle, one spring member is largely bent, that is, a large drag force is generated in one spring member, and the sub-reflector 4 returns to the center position by the spring. This is performed until the drag force of each member becomes the same, and the center of the sub reflector can be easily matched with the center.

[Effect of device]

As described above, according to the present invention, the vehicle lamp is
A sub-reflector, whose lower part is rotatably supported around the lower part of the bulb standing from the bottom side of the lamp chamber, and whose upper part is connected to the driving means via a pin that passes through the upper flat part of the reflector, is attached to the front face of the reflector. A sub-reflector which is arranged so as to be rotatably movable by the driving means, and circular holes corresponding to socket holders for supporting the bulb are respectively provided under the reflector and the sub-reflector, and the sub-reflector of the sub-reflector is provided. The peripheral edge of the circular hole and the peripheral edge of the circular hole of the reflector are arranged so as to be slidable via a resin ring so as to correspond to each other.
A lower portion of the sub reflector is rotatably coupled to a lower flat surface portion of the reflector, and a peripheral edge of an insertion hole through which the pin of the upper reflector portion is inserted is provided with a drainer formed by bending the peripheral edge of the insertion hole upward. Since one urging member consisting of a pair of spring members, each of which abuts in a biased state with its tip open to the fixed portion inside the lamp chamber, is provided above the pin, the sub reflector contacts the socket holder. The rotary movement of the sub-reflector can be smoothed without causing any trouble, and water can be surely prevented from entering the inside through the pin insertion hole in the upper plane portion of the reflector. Further, the structure for returning the sub-reflector to the center is simple and does not complicate the operation of assembling the lamp, which is an effect of excellent practicality.
