Description

[Detailed explanation of the idea] The present invention relates to an auxiliary headlamp with a wiper.

2. Description of the Related Art Hitherto, a headlamp with a wiper is known as a vehicle lamp equipped with a wiper device, such as a headlamp for a vehicle such as an automobile.

However, with regard to auxiliary headlights such as fog lamps and spot lamps installed below the headlights, there are no known ones that come with wiper devices.

Such auxiliary headlights are also desired to be equipped with a wiper device, since sewage, mud, etc. may adhere to the lens surface when the lights are turned on, making it impossible to obtain an appropriate light distribution.

However, in conventional headlights with wipers, a nozzle is installed on the wiper blade to spray washer fluid.

This configuration is difficult to apply to an auxiliary headlamp, which generally has a smaller lens surface than a headlamp, and therefore requires a smaller wiper blade.

Furthermore, the washer liquid injection nozzle of conventional headlamps with wipers does not have a structure that protects the nozzle even when the washer liquid is not being injected, and therefore the nozzle is free from dirt, gravel, and other foreign objects. If this happens, the washer liquid may not be properly ejected, resulting in a decrease in the amount of washer liquid and the inability to wipe properly.

Sometimes the nozzle becomes clogged, making it impossible to spray.

In view of the above circumstances, the present invention includes a stopper for locking the wiper blade protruding from the frame body, and an injection port for injecting washer fluid toward the outer surface of the lens formed in the stopper. This eliminates the need to form a nozzle nozzle toward the wiper blade, and the wiper blade is configured to block the nozzle in the spray direction when the wiper blade is stopped, so that the wiper blade protects the nozzle when the washer fluid is not being sprayed. To provide an auxiliary headlamp with a wiper capable of preventing clumps and other foreign matter from entering an injection port.

An example of the implementation of the present invention will be described below with reference to FIGS. 1 to 4.

In this example, the present invention is applied to an automobile fog lamp or an automobile spot lamp.

A front view is shown in FIG. 1, and sectional views taken from different directions are shown in FIGS. 2 and 3.

FIG. 4 shows a cross-sectional view of the injection port.

As shown in FIGS. 1 to 3, this lamp has a lens 1
The lens 1 includes a frame 2 surrounding the periphery of the lens 1, and a wiper blade 3 for wiping the surface of the lens 1.

A stopper 4 is provided on the front surface of the frame 2 to project forward.

This stopper 4 serves to stop the wiper blade 3 from moving further to the right in the figure in the state shown in FIG. 1.

This stopper 4 is formed with an injection port 5 for injecting washer liquid toward the outer surface of the lens 1.

In this example, as shown in FIG. 4, the washer liquid led from a tube 51 made of rubber or the like is passed through a path 52 in the stopper 4, and then passed through a small hole 53 opened laterally from the path 52.
The liquid is ejected through the small hole 53 using the opening as the injection port 5.

The injection port 5 opens toward approximately the center of the surface of the lens 1, as shown in FIG.

Further, the wiper blade 3 is configured to block the above-mentioned injection port 5 in the injection direction when it is stopped.

This state is as shown in FIG.

In other words, when the wiper blade 3 is stopped, it is at the stop position where it is stopped by the stopper 4, and at this time, it blocks the injection port 5 at a position exactly in front of the injection direction.

With this configuration, when no washer liquid is supplied, the injection port 5 is always shielded by the wiper blade 3 and protected from the outside.

Therefore, dirt and other foreign substances are prevented from entering the injection port 5, and cleaning performance is reduced due to a decline in injection performance, and the injection port 5 is prevented from entering.
It is possible to reliably prevent situations such as failure to eject due to blockage.

This effect can be achieved by having the wiper blade 3 not necessarily close to the nozzle 5 to block it, but even if the wiper blade 3 is a little distant, it can block the nozzle 5 in front of the nozzle 5 in the spray direction.

Moreover, according to this configuration, since the injection port 5 is formed in the stopper 4 for the wiper blade 3, the conventional nozzle and this stopper can be used together, and the configuration is simple and advantageous in manufacturing. , it has a clean appearance.

In addition, since the protective part of the jet nozzle 5 is remotely connected to the wiper blade 3, it is advantageous that the jet nozzle 5 can be protected remotely with a simple structure without requiring a special protective part or cover of a separate member. .

Since there is no need to provide a nozzle on the wiper blade, the structure can be simplified and downsized, and it goes without saying that this structure is advantageous when used in an auxiliary headlamp.

Furthermore, on the left side of FIG. 1, there is a locking stopper 4' that restricts the movement of the wiper blade 3 in the leftward direction.

This is only for locking purposes and does not have an injection port.

The stopper 4 is a substantially small cylindrical projection, and the locking stopper 4' is a substantially small truncated conical projection. Unlike the case of a surface-contact locking wall, wiped rainwater does not accumulate and falls immediately, which is advantageous since there is no risk of freezing.

Further, as shown in the figure, the wiper blade 3 of this example includes a rubber ribbon 31 as a wiping part, a stay 32 that supports the rubber ribbon 31, a wiper arm 33 that supports the stay 32 and makes it rotate, and a holder 34. Lever arm 33
The pivot shaft 34 is attached to the pivot shaft 34 and provides the driving force for pivoting.

(Although FIG. 3 is a side sectional view of FIG. 1, it is shown with the wiper blade 3 positioned along the vertical direction in order to clearly show the configuration of the wiper blade 3.)

In the figure, 6 is a bulb (light bulb), 61 is a shade that blocks the light emitted from the bulb 6 in a certain direction (light that becomes direct light to the front), and 62 is a shade that reflects the light from the bulb 6 toward the lens 1. This is a nearly parallel ray of light.

The reflector 62 and the lens 1 constitute a lamp body, and the lamp body is sandwiched and supported between the lamp housing 7 and the frame body 2 as shown in FIG.

A bolt 71 connects the housing 7 and the frame 2.

The frame 2 can be formed as a so-called rim.

The frame 2 of this example has a concave part 21 at the bottom, which is recessed from the surface of the lens 1, but the other parts are the concave part 21.
The surface has a height that almost corresponds to the surface of stopper 4.
, 4' also protrude from here.

In FIG. 3, 22 is a drain hole.

35 is a wiper driving motor.

As mentioned above, the auxiliary headlight with a wiper of the present invention has a stopper protruding from the frame surrounding the lens that locks the wiper blade that wipes the lens surface. The wiper blade is configured to have a nozzle that injects the washer fluid, and the wiper blade is configured to block the nozzle in the spray direction when the wiper blade is stopped. The nozzle can be protected, and therefore dust and other foreign matter can be reliably prevented from entering the nozzle, and good wiping can always be achieved.

In addition, since the jet nozzle is also used as a stopper, it has a clean and simple structure in appearance, and there is no need to provide a nozzle on the wiper blade, making it advantageous for use in auxiliary headlights. have

It should be noted that, as a matter of course, the present invention is not limited to the illustrated embodiment.
