Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a lamp for a vehicle, and more particularly to a lamp suitable for a high mount stop lamp for an automobile.

[Conventional technology]

FIG. 3 is an explanatory view of a high mount stop lamp, in which a high mount stop lamp 1 is provided behind a rear seat 2 of an automobile.

The high mount stop lamp 1 lights up when the vehicle is braked to give a warning to the following vehicle.

FIG. 4 is a sectional view showing a conventional example of a high mount stop lamp.

A front cover 4 is fitted in the front opening of the lamp housing 3. In the figure, i is a spigot fitting part.

A reflector 5 and a light source bulb 6 are installed in a space surrounded by the lamp housing 3 and the front cover 4. Reference numeral 5a is a pillar of the reflector, and 5b is a curved plate of the reflector.

The bottom plate 3a of the lamp housing 3 and the bottom plate 4a of the front cover 4
And are configured so as to extend toward each other, and are overlapped with each other.

In this conventional example, a mounting screw 6 is inserted through a through hole provided in each of the bottom plate 3a and the bottom plate 4a, and the mounting screw 6 is screwed into the reflector column 5a to fasten both bottom plates 3a, 4a. There is.

When a reflector separate from the lamp housing 3 is not provided, the mounting screw 6 is inserted into the through hole provided in the bottom plate 3a, and the mounting screw 6 is attached to the screw boss (not shown) provided in the bottom plate 4a. The bottom plates 3a and 4a are fastened by screwing.

[Problems to be solved by the device]

In the conventional example shown in FIG. 4, the overlapping surfaces S-S of the two bottom plates 3a and 4a and the mounting screws 6 are substantially vertical, and the screw through holes of the bottom plates 3a and 4a are stupid holes. Since there is a mounting screw 6
Even if the lamp housing 3 is tightened, the lamp housing 3 and the front cover 4 are not positioned relative to each other, and the front cover 4 is not firmly attached to the lamp housing 3.

On the other hand, vehicle lamps are often subject to vibrations and shocks while the vehicle is running. When the conventional example shown in FIG. 4 is subjected to vibration and impact, the inlay fitting portion indicated by reference numeral i in the drawing may open its mouth.

The present invention has been made in view of the above circumstances, and the lamp housing and the front cover are tightly adhered and firmly fixed by tightening the mounting screw, and the fitting portion opens the mouth even when subjected to vibration or shock. An object of the present invention is to provide a vehicular lamp without fear.

[Means for Solving the Problems]

In order to achieve the above object, the vehicular lamp of the present invention has a front cover fitted in a front opening of a lamp housing, and extends toward the mating member on the bottom plate of each of the lamp housing and the front cover. In the vehicle lamp in which the protruding plate-shaped portions are integrally formed, and the plate-shaped portions of both members are overlapped and the overlapped portions are fastened with a screw member, the plate-shaped portion provided in the lamp housing A stepped slope having an inclination angle with respect to the center line of the screw member is formed on at least one of the portion and the plate-shaped portion provided on the front cover, and the plate provided on the lamp housing. The other of the plate-shaped portion and the plate-shaped portion provided on the front cover is provided with a positioning surface that is in close contact with the inclined surface.

[Action]

According to the above configuration, when the mounting screw is tightened, the slope and the positioning surface come into contact with each other, and when the slope angle of the slope is appropriately set, the force of the slope causes a force larger than the tightening force of the screw. Since the bottom plates come into close contact with each other, the lamp housing and the front cover are firmly restrained and integrally joined,
There is no fear that the fitting portion will separate even if it receives vibration or impact.

〔Example〕

FIG. 1 is a sectional view showing an embodiment of a vehicular lamp according to the present invention.

This embodiment is an improvement by applying the present invention to the high mount stop lamp of the conventional example shown in FIG. 4, in which the same reference numerals as those in FIG. The same or similar component.

It is the part II surrounded by the phantom line that has been improved by applying the present invention. An enlarged view of the part II is shown in FIG.

A part of the bottom plate 3b of the lamp housing 3 is bent so as to be bent to form a stepped slope 3b _-1 having an inclination angle θ with respect to the center line of the mounting screw 6.

On the other hand, a part of the bottom plate 4b is folded down to form a bent portion 4b _-1 that covers the stepped slope 3b _-1 , and the bent portion 4b _-1 is the stepped slope 3b.
_A positioning surface _4b-2 is formed on the side facing _b-1 and is brought into close contact with the stepped slope _3b-1 .

In this example, the angle θ is set to about 10 degrees.

According to an experiment by the present inventor, when the present invention is carried out, it is easy to obtain a good result when the angle θ is set to 10 degrees to 10 degrees or more.

When the mounting screw 6 is tightened, the bottom plates 3b and 4b are crimped in the vertical direction in the figure. Since both of the bottom plates are in sliding contact with each other along a surface that intersects the tightening direction of the screw (vertical direction in the drawing) at an angle θ, the slanted surface allows positioning in the horizontal direction in the drawing.

Further, as can be easily understood from FIG. 1 and FIG. 2, even if the vehicular lamp of this embodiment receives vibration or impact,
As long as the mounting screw 6 does not loosen, the front cover 4 is not displaced in the separating direction with respect to the lamp housing 3. This is because the positioning surface _4b-2 is in close contact with the stepped slope _3b-1 .

As an embodiment different from the above, when the reflector 5 shown in FIG. 1 is not installed, a screw boss (not shown) corresponding to the reflector column 5a shown in FIG. 2 is formed integrally with the bottom plate 4b. However, the same action and effect as in the previous example can be obtained.

[Effect of device]

As described above, the vehicular lamp of the present invention has at least one of the plate-shaped portion provided on the lamp housing and the plate-shaped portion provided on the front cover inclined with respect to the center line of the screw member. A simple step of forming a stepped slope having corners and providing a positioning surface in close contact with the slope on the other of the plate-shaped portion provided on the lamp housing and the plate-shaped portion provided on the front cover. Due to the configuration, the lamp housing and the front cover can be firmly coupled, and the excellent practical effect that the fitting portion is not likely to be disengaged even if subjected to vibration or shock is given, and the opportunity to receive vibration or shock is provided. It is suitable as a vehicular lamp with a lot of light.
