Description

[Detailed explanation of the idea] (Industrial application field) This invention relates to a vehicle lamp.

(Prior Art) Some vehicle lamps are equipped with a function to prevent misassembly so that the lens is not placed in the wrong orientation when the lens is attached to the front of the housing.

This type of lighting equipment is, for example, as shown in Figure 4.
A projection b is provided on the inner surface of the lens a, and a recess e is provided in the housing d into which the light bulb c is inserted, and the projection b is fitted into this recess to prevent incorrect assembly.

(Problems to be Solved by the Invention) The above-mentioned misassembly prevention structure merely prevents misassembly and does not have a waterproof function.

This invention aims to provide a vehicle lamp that not only has a function to prevent misassembly but also has waterproof and inflow prevention functions.

(Means for solving the problem) As a means for solving the above problem, this invention provides a waterproof rib on the upper part of the light bulb mounting part of the housing, which also serves to prevent incorrect assembly.
A lens that is installed on the front side of the housing has a rib at the bottom to prevent inflow, and the lens is installed on the inner surface of both sides of the drain hole formed at the bottom to prevent incorrect assembly of the housing if the lens is installed upside down. The gist is that an inflow prevention rib is provided which also serves to prevent incorrect assembly from hitting the waterproof rib which also serves as a waterproofing rib.

(Example) This invention will be specifically explained below with reference to the illustrated example. Reference numeral 1 designates a housing made of rubber or the like, into which a light bulb 2 is inserted into a light bulb mounting portion in the center, and an arcuate waterproof rib 1a is formed on the upper part of the housing to prevent misassembly. Further, a rib 1b for preventing inflow is formed at the lower part of the housing 1, and this is for preventing water that has entered through a drain hole of the lens, which will be described later, from flowing into the light bulb 2 side. 3 is a lens made of synthetic resin or the like;
A drain hole 3a is formed in the lower part thereof, and inflow prevention ribs 3b which also serve to prevent incorrect assembly are formed on the inner surfaces on both sides of the drain hole 3a. This lens 3
The mounting bosses 3c formed on both sides are aligned with the mounting holes 1c of the housing 1, and can be fixed with screws 4. If the lens 3 is turned upside down during installation, Since the rib 3b of the lens 3 collides with the rib 1a of the housing, it is easy to see that the lens 3 is assembled incorrectly.

On the other hand, when the lens 3 is properly attached to the housing 1, the water drain hole 3a of the lens 3 is surrounded by the rib 3b of the lens and the lower rib 1b of the housing. Note that 5 is a cord for energizing.

The vehicle lamp according to this invention is constructed as described above, and the rib 1a on the upper part of the housing 1 and the rib 3b on the inner surface of the lens 3 can exhibit the function of preventing misassembly, and the rib 1a of the housing is , it is possible to prevent water that has entered from the upper part of the lamp from flowing down to the two parts of the light bulb, and to exhibit a waterproof function;
Furthermore, the rib 3b of the lens 3
Together with the ribs 1b formed at the lower part of the lens 3, the lens 3 can exhibit a waterproof function by repelling muddy water and the like that have entered through the drain hole 3a and preventing it from flowing into the inner part.

(Effects of the invention) As explained above, according to this invention, the combination of the ribs formed on the housing and the ribs formed on the lens provides not only a function to prevent incorrect assembly but also a waterproof function. The practical effect is extremely remarkable.
