Abstract

PURPOSE:To enable the lens surface of a retractable lamp to be flush with the outer surface of a vehicle body when the lamp is stored, by providing a holding member which holds the lamp in the condition of optical axis adjustment at the position where a support member is used, and which releases the condition of optical axis adjustment during turning of the lamp to the storage position. CONSTITUTION:When a link 48 for rotating a motor 46 is turned to the side remote from a support member 4, a hold member 6 is rotated toward its release position, and accordingly, the holding positions of both optical axis adjusting screws 70, 76 are retracted while a lamp 52 is tilted by means of a spring 84 until round shape nuts 74, 80 abut against the support member 4. At this time the position of the lamp 52 with respect to the support member 4 is such that the lens surface 58 of the lamp 52 is made to be flush with the outer surface 86 of the vehicle body when the support member 4 is at its storage position. When a stopper 32 abuts against the support member 4, the hold member 6 is limited while the support member 4 is rotated to the storage position by a drive means 44 until it abuts against a stopper 12 so that the lamp 52 is stopped and positioned in the stored condition. Thus, the lens surface is made to be flush with the outer surface of the vehicle body, thereby it is possible to reduce noise and to prevent foreign object from being introduced.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention provides a method in which the lamp is placed supine in a retracted state and is erected in a use position where the lamp is turned on.
This invention relates to a retractable headlamp of a type generally called an exposed type.

(Prior Art) As conventional exposed type retractable headlamps, those described in Japanese Patent Application Laid-Open No. 53-107044 and Japanese Utility Model Application Publication No. 57-170337 are known.

These retractable headlamps are provided with a support member that is rotatable with respect to the vehicle body, a lamp that is tiltable with respect to the support member, and is provided between the support member and the lamp to adjust the amount of tilting of the lamp. The lamp is equipped with an optical axis adjustment screw that adjusts the optical axis of the lamp.
It was designed to stand up when in use.

(Problems to be Solved by the Invention) However, in such conventional retractable head lamps, since the lamp is fixed to the support member with an optical axis adjustment screw, it is difficult to adjust the optical axis of the lamp at the use position of the support member. When the optical axis was adjusted to the normal optical axis, a step was created between the lens surface of the lamp and the outer surface of the vehicle body when the support member was rotated to the storage position. Even if the design is such that the lens surface of the lamp after optical axis adjustment is flush with the outer surface of the vehicle body in the retracted state, there may be differences in level due to errors in parts and assembly during the manufacturing process, variations in load distribution, etc. This caused the problem that the lens surface of the lamp was not flush with the outer surface of the vehicle body.

Furthermore, if the lens surface of the lamp is not flush with the outer surface of the vehicle body when in the retracted position, it will look bad and cause wind noise and noise. If a large gap is created, there is a problem in that foreign matter can become trapped, causing failure.

(Means for Solving the Problems) The present invention has been made for the purpose of solving the above-mentioned problems, and as a means for that purpose, the retractable headlamp of the present invention has two positions: a storage position and a use position on the vehicle body. In the retractable headlamp, a support member is rotatably provided, a lamp is tiltably supported by the support member, and the lamp lies supine in a storage position of the support member and stands up in a use position of the support member, as described above. A holding member is provided that holds the lamp in an optical axis adjusted state when the supporting member is in the use position, and releases the optical axis adjusted state of the lamp when the support member is rotated from the use position to the storage position. I decided to do so.

(Function) Therefore, the lamp is held by the holding member in the use position of the support member, and in this state, the lamp is adjusted to the normal optical axis, and the optical axis is adjusted so that the lamp is always oriented in a certain direction when the lamp is in use. is obtained.

In this restricted state, the lamp 52 is positioned so that the lens surface 58 of the lamp 52 is flush with the outer surface 86 of the vehicle body.

Next, the operation of the embodiment will be explained.

First, a case will be described in which the lamp 52 is raised from a supine position.

FIG. 4 shows the lamp 52 in a supine state.
The support member 4 is located in the storage position whose position is regulated by the storage position stopper 12, and the lamp 52 is placed in the first position.
The position of the lens surface 58 is regulated by the lamp stopper 88 and the second lamp stopper 89 so that the lens surface 58 is positioned on the outer surface 86 of the vehicle body.

However, the release position stopper 32 is regulated to the release position in contact with the support member 4, and the first link 48 is
It is located on the opposite side to the support member 4.

Next, when the motor 46 is rotated, the first link 48 is rotated toward the support member 4, whereby the second link 50 presses and rotates the holding member 6.

When the holding member 6 is rotated, both optical axis adjustment screws 7
When it comes into contact with the support position stopper 30 and support grommet 82 of 0 and 76, both optical axis adjustment screws 70 and 7
6 tries to advance from both the insertion holes 22 and 24 of the support member 4, but its advance is prevented by the resistance of the tilting spring 84, and the support member 4 is position-regulated together with the support member 4 at the use position stopper 14. It is rotated until.

Thereafter, the holding member 6 overcomes the resistance of the tilting spring 84 and rotates further, so that the support position stopper 30
When the stopper surface 302 is rotated to the use position where it comes into contact with the support member 4, the driving of the drive means 44 is stopped and the support member 4 is fixedly held.
The state shown in the figure will be reached.

As shown in FIG. 1, when the support member 4 is located at the use position and the holding member 6 is located at the holding position, the support position stopper provided on the base end side of both optical axis adjustment screws 70 and 76 is 30 and the support grommet 82 are held by the holding member 6, and in the held state, by rotating both the optical axis adjustment screws 70 and 76 to change the screwing position with the lamp 52, the lamp 52 can be moved to the ball joint. The optical axis direction of the lamp 52 can be adjusted by tilting it vertically and horizontally around the portion 64.

The position of the lamp 52 after this adjustment becomes the use state position.

Next, a case will be described in which the lamp 52 is turned from an upright position to a supine position.

Rotate the motor 46 from the state shown in FIG.
When the first link 48 is rotated to the side opposite to the support member 4, first, the holding member 6 is rotated to the release position side where it is separated from the support member 4.

As the holding member 6 rotates, the holding positions of both the optical axis adjustment screws 70 and 76 are moved backward, and the lamp 52 is accordingly moved by the biasing force of the tilting spring 84 as shown in FIG. When the round nut 74 as the first lamp stopper 88 and the round nut 80 as the second lamp stopper 89 are tilted until they come into contact with the support member 4, the position of the lamp 52 with respect to the support member 4 at that time is as follows. Support member 4
when the lens surface 5 of the lamp 52 is in the retracted position.
8 is a position where it is flush with the outer surface 86 of the vehicle body (storage state position).

Next, when the release position stopper 32 of the holding member 6 comes into contact with the supporting member 4, the rotation of the holding member 6 is restricted, and the driving force from the driving means 44 is transmitted to the supporting member 4 via the holding member 6. and the support member 4 is rotated toward the storage position.

Thereafter, the support member 4 is rotated to the retracted position where its rotation is restricted by the retracted position stopper 12, the lamp 52 is placed in the retracted state position, and the driving of the drive means 44 is stopped.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention may be modified without departing from the gist of the present invention. included.

For example, the support position stopper may be provided on the support member 4, the holding member 6, or the pivoted portions of both, and the same applies to the release position stopper 32.

Further, the tilting spring 84 is provided between the support member 4 and the optical axis adjustment screws 70, 76.
6 may be moved in the direction of the holding member 6, the lamp 52 may be tilted. Alternatively, the holding member 6 and the optical axis adjustment screws 70, 76 may be connected It may also be provided between the support member 4 and the holding member 6 above.

In addition to being provided between the lamp 52 and the support member 4, the lamp stopper 88 is also provided between the lamp 52 and the vehicle body 10, and between the optical axis adjustment screws 70, 76 and the support member 4 or the holding member 6 or the vehicle body 10. It may be provided in between.

Further, although the lamp 52 is provided so as to be tiltable vertically and horizontally by the ball joint portion 64 and the joint portion 26, it may not necessarily be tiltable vertically and horizontally, but may be tiltable only in the vertical direction. , only one optical axis adjustment screw is required.

(Effects of the Invention) As described above, in the retractable headlamp of the present invention, the lamp is held in the optical axis adjusted state when the support member is in the use position, and when the support member is rotated from the use position to the storage position. By providing a holding member that releases the optical axis adjustment state of the lamp, the lens surface of the lamp is always regulated to a constant position when the support member is in the retracted position. This has the effect of making it flush with the outside surface, and as a result, there is no difference in level between the lens surface of the lamp and the outside surface of the vehicle body, which improves the appearance and reduces wind noise. Another effect can be obtained in that a gap can be prevented from forming between the vehicle body and the lamp.

Furthermore, since the lamp is oriented in the optical axis adjusted state in the use position of the support member, an effect can be obtained in that the normal optical axis of the lamp can be obtained in the use state of the lamp.

Further, in the embodiment, since the lamp can be tilted vertically and horizontally with respect to the support member, and two optical axis adjusting screws are provided, the optical axis of the lamp can be adjusted vertically and horizontally.

In addition, since the support position stopper and the support grommet are provided on the optical axis adjustment screw, by adjusting the positions of both before fixing them to the optical axis adjustment screw, it is possible to adjust the position of the lamp relative to the support member during use. Can be done.
