JPS5817281Y2 - Headlight with wiper - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a headlamp for an automobile having a blade-type wiper attached to the front.

In this type of headlamp with a wiper, when the wiper is not in use, that is, when the wiper is stopped, the wiper blade is located below the front lens and covers a portion of the effective light emitting surface, resulting in a reduction in illuminance.

In foreign headlight wiper standards, the light distribution change rate between with and without a wiper blade is set at 3% or less, but as mentioned above, when the blade is stopped at the bottom of the front lens, the change in light distribution is 3% or less. The ratio exceeds 3%, making it impossible to satisfy the wiper standards.

Therefore, it is necessary to remove the wiper blade from the front lens when it is not in use, but it is extremely troublesome to attach or remove it during actual use, making it impractical.

This invention was created in view of these circumstances,
The purpose is to provide a headlamp with a wiper in which the rate of change in light distribution is 3% or less even when the wiper blade is stopped below the front lens.

The present invention, which was made in order to achieve this objective, has a lens part that is located on the lower side of the front lens when the wiper blade stops, and a flange part of the opening at the bottom of the flap that corresponds to this lens part. This is a headlight with a wiper, which is characterized by having a non-light-emitting part that does not irradiate light by forming the blade slightly wider than the width of the blade.Since the stopping position of the blade is fixed, this stopping position is As long as it is set as a non-light emitting part, it does not matter whether there is a blade or not, and the rate of change in light distribution will not change at all.

Next, the present invention will be explained in more detail with reference to the illustrated embodiment. Reference numeral 1 is a rectangular headlamp, in which a reflector 3 is attached inside a housing 2, and a backing 4 is sandwiched between the front side and a clip or rim 5. A front lens 6 is attached through the lens.

A light bulb 7 is attached as a light source to the center of the bottom of the reflector 3, and a rubber cover 8 is attached to cover the bottom of the housing.

A pair of blade stoppers 9 are provided on the lower side of the front lens 6, and a wiper blade 10 is provided that stops by coming into contact with the stoppers, and the wiper blade 10 is moved in the vertical direction by a drive arm 11. .

The j-flafter 3 has a flange portion formed around the periphery of the opening, but the lower flange portion 3a is formed wider than the upper flange portion 3b, and the lower flange 3a provides a non-emissive portion to the lens portion 6a where the blade is stopped. Form part a.

Considering this, the flange portion 3 a of the reflector 3
, 3b are in the relationship 3a > 3b, and the flange portion 3b may be made narrower by the width of the flange portion 3a, and at the same time, the width of the flange portion 3a may be made slightly wider than the width of the flange 10. It's good to keep it.

Note that the shaded area in FIG. 2 is an effective light emitting section.

By forming it in this way, the front and lower part of the headlight where the wiper blade stops becomes a non-light emitting part,
From the beginning, no light rays reach this non-light-emitting area, and the light distribution characteristics remain the same whether or not the wiper blade is located at this position, and the rate of change is 0.

As explained above, the headlight with a wiper according to the present invention is
A non-light-emitting part that was not originally planned as an illumination part was formed in the lower part of the headlight, that is, in the lower part of the front lens, and the wiper blade was configured to stop at this non-light-emitting part. As long as the blade is located at
It no longer blocks the light emitted from the headlights, and even if there is a blade in front of the headlights, the rate of change in light distribution does not change at all, and it complies with wiper standards and can be used legally. becomes.

Claims (1)

[Scope of utility model registration request] The lower part of the front lens, which is located when the wiper blade is stopped, is made to correspond to this lens part, and the lower opening flange part of the flap is formed to be slightly wider than the width of the blade, thereby allowing light to pass through. A headlight with a wiper that is characterized by having a non-light-emitting part that does not emit light.
