Description

[Detailed Description of the Invention] The present invention relates to a structure that prevents a vehicle lamp from being incorrectly attached to a vehicle body.

Conventionally, most vehicle lamps have a substantially rectangular front shape and are symmetrical vertically and horizontally. As a result, vehicle lamps are sometimes installed upside down, and once installed, it is difficult to detect incorrect installation.

The present invention was developed in consideration of the above-mentioned drawbacks.The housing of the lamp body is molded from a flexible resin, and protrusions are provided facing each other on both the front and back surfaces of the housing, and the lamp body is attached to the housing. The car wall has an insertion part into which the protrusion provided on the back of the front part is inserted, which prevents the vehicle light from being installed upside down, and also prevents the vehicle light from being installed after it has been installed. The purpose is to make it possible to check from the outside whether it is correct or not.

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

In the figure, reference numeral 1 denotes a vehicle lamp in which a lamp lens 3 is attached to the front surface of a lamp body 2. The housing 4 of the lamp body 2 is molded from a flexible resin and has a rectangular front shape corresponding to the lamp lens 3. is engaged.
A light bulb mounting portion 42 having a substantially V-groove cross section is recessed in the center of the housing 4, and the light bulb mounting portion 42 is inserted into an opening hole 50 made in the car wall 5 corresponding to the light bulb mounting portion 42. The vehicle lamp 1 is attached to the car wall 5 by screwing the lamp lens 3 and the front part 41 of the housing 4 to the car wall 5. As shown in FIG. 1, an upper protrusion 6 is integrally formed on the surface of the front part 41 of the housing 4 in the vicinity of the light bulb mounting part 42, and the protruding end of the upper protrusion 6 is connected to the cut of the lamp lens 3. It is provided close to the surface 31. Further, a lower protrusion 7 that faces the upper protrusion 6 and protrudes in the opposite direction is integrally formed on the back surface of the front part 41. An insertion portion 51 into which the lower projection 7 is inserted is provided in the opening hole 50 of the vehicle wall 5 so as to be continuous with the opening hole 50. When the vehicle lamp 1 is thus properly installed, the lower protrusion 7 is located in the insertion portion 51, as shown in FIG.
Also, if you accidentally try to install it by turning it upside down, the lower protrusion 7 will come into contact with the periphery of the opening hole 50, creating a gap between the vehicle wall 5 and the vehicle light 1, which will alert the installation worker to the incorrect installation. be able to. Furthermore, even when the vehicle lamp 1 is installed upside down, the upper protrusion 6 comes into contact with the cut surface 31 of the lamp lens 3 and the upper protrusion 6 passes through the lamp lens 3, as shown in FIG. The protruding end can be seen and the installation worker can be notified of incorrect installation.

Therefore, according to the present invention, the housing of the lamp body is molded from a flexible resin, and an upper projection is provided on the front surface of the housing close to the lamp lens, and a lower projection is provided opposite to the upper projection. is provided on the back of the front part of the housing, and there is an insertion part in the car wall into which the lower protrusion is inserted, so if you try to install the vehicle lamp upside down, the lower protrusion will come into contact with the car wall and it will not be installed incorrectly. In addition, even if the lamp is installed upside down, the upper protrusion will come into contact with the cut surface of the lamp lens and the protruding end will be visible through the lamp lens, even after installation. It is possible to easily check whether the device is properly attached or not, and is effective in preventing and detecting incorrect attachment.
