[0001] Washing apparatus for automotive lamp [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning device for a vehicle lamp for cleaning a lamp for a vehicle, and more particularly, to a cleaning device for a lamp for a vehicle that can compensate a tolerance generated when a nozzle cover is coupled to the nozzle.

Generally, a vehicle has a lamp having a lighting function for easily confirming an object located in the vicinity of the vehicle at nighttime, and a signal function for notifying other vehicle or road users of the running state of the vehicle. For example, headlights and fog lights are for illumination purposes, and turn signals, tail lights, brake lights, and side markers are signals. Inside the vehicle, there are additionally provided interior lamps that are turned on in conjunction with door opening and map lamps that can be used to view maps and books.

Vehicle lamps are considered to be very important in the appearance of the vehicle in addition to functions for lighting and signaling. Moreover, at night, the appearance of the vehicle is determined depending on the shape of the vehicle lamp. Thus, as the exterior design of a vehicle lamp becomes more and more important as well as the performance of a vehicle, there is an increasing demand for a vehicle lamp having various appearance designs while satisfying the requirements of a lighting function and a signal function.

Among them, the headlight is an illumination device that is necessary for night driving, and the illuminance, the angle of illumination, and the irradiation distance are prescribed by the law according to the vehicle type.

However, when the vehicle is not provided with a separate cleaning device for removing dust or foreign matter from the headlight, if the front surface of the headlight is filled with a lot of dust or dust, the desired level of illumination can not be obtained, It becomes difficult to realize the appearance design. Particularly, when the vehicle can not secure a sufficient front view when driving on a road not equipped with a street light, it is difficult to identify the state of the road ahead and obstacles, thereby increasing the possibility of vehicle accidents.

In recent years, there has been provided a cleaning device including a nozzle capable of spraying a cleaning liquid toward a lamp on one side of a vehicle lamp in order to secure a sufficient forward view field and realize a satisfactory appearance design. In a normal state, And the nozzle for spraying the cleaning liquid only when the lamp is cleaned is exposed to the outside of the vehicle, so that the lamp is cleaned.

At this time, the nozzle and the nozzle cover are manufactured according to a predetermined standard and are coupled to each other. If a problem in the manufacturing process, such as shrinkage in the cooling process, occurs, the tolerance may deviate from the original standard. At this time, when a clearance due to the tolerance occurs in the nozzle and the nozzle cover, the nozzle cover can not completely block the nozzle, so that foreign matter may flow into the nozzle cover or the nozzle cover may be shaken and damaged.

Accordingly, there is a demand for a method that can minimize the occurrence of clearance by compensating for the tolerance generated when the nozzle and the nozzle cover are coupled.

A problem to be solved by the present invention is to provide a cleaning device for a vehicle lamp which can compensate for tolerance in order to minimize generation of clearances due to tolerance when a nozzle and a nozzle cover are combined.

The tasks of the present invention are not limited to the tasks mentioned above, and other tasks not mentioned may be clearly understood by those skilled in the art from the following description.

According to an aspect of the present invention, there is provided a vehicle lamp cleaning apparatus including: a nozzle formed at one end of a piston moving in one direction to spray a cleaning liquid toward a lamp; And a nozzle cover having an extension part and a latch part formed along the direction in which the nozzle is coupled and having a plurality of latching grooves for latching one end of the extension part.

Other specific details of the present invention are included in the detailed description and drawings.

According to the vehicle lamp cleaning apparatus of the present invention as described above, there are one or more of the following effects.

It is possible to compensate the tolerance by adjusting the engaging grooves which are caught in the extended portion even when a plurality of engaging grooves formed by extending one end of the extended portion formed from the nozzle on the nozzle cover are arranged along the engaging direction of the nozzles, There is an effect that the occurrence can be minimized.

In addition, a structure for guiding the nozzle and the nozzle cover is formed to prevent misassembly and to prevent the nozzle cover from being detached from the nozzle.

The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by those skilled in the art from the description of the claims.

Hereinafter, the present invention will be described with reference to the drawings for explaining a cleaning device for a vehicle lamp according to embodiments of the present invention.

1 and 2 are perspective views showing a cleaning device for a lamp for a vehicle according to an embodiment of the present invention.

As shown in the drawings, a cleaning apparatus 1 for a vehicle lamp according to an embodiment of the present invention includes a housing 100 into which a cleaning liquid flows, a piston 200 moving in one direction through the inside of the housing 100, a piston 200, A nozzle 300 formed at one end of the nozzle 300 for spraying the cleaning liquid toward the lamp, and a nozzle cover 400 coupled to the nozzle 300.

The housing 100 is installed inside the vehicle body 10 of the vehicle and can be formed with a washing liquid inlet port through which the washing liquid flows. The piston 200 is also rotated by the hydraulic pressure generated by the washing liquid flowing through the washing liquid inlet port 1 and the opening 11 of the vehicle body 10 as shown by the arrows in Fig.

In the embodiment of the present invention, the case where the piston 200 is pushed by the hydraulic pressure due to the cleaning liquid flowing into the housing 100 and is restored to the original position when the hydraulic pressure is removed will be described as an example. However, But the present invention is not limited thereto.

When the piston 200 is pushed out in one direction by the cleaning liquid flowing into the housing 100, the piston 200 is exposed to the outside of the vehicle through the opening 11 formed in the vehicle body 10. In this state, So that the lamp can be cleaned. In the embodiment of the present invention, a case where the nozzle 300 cleans the headlamp will be described by way of example. In this case, the opening 11 is formed at a portion adjacent to the headlamp, for example, For example.

However, the present invention is not limited to this. For example, the lamps to be cleaned according to the first embodiment of the present invention may be used in the vehicle 1 shown in Figs. 1 and 2, The positions of the cleaning device 1 and the opening 11 of the lamp may be variously changed.

That is, in the present invention, the nozzle cover 400 is coupled to the nozzle 300. When the lamp is not cleaned, the nozzle cover 400 shields the opening 11. When the lamp is cleaned, The nozzle cover 400 is moved in one direction by the nozzle 200 together with the nozzle 300 so that the opening 11 is opened.

When the nozzle 300 and the nozzle cover 400 are coupled to each other, it is required to prevent clearance between the vehicle body 10 and the nozzle cover 400 in a state where the opening 11 is shielded. In other words, even if the nozzle cover 400 is manufactured on the basis of a predetermined standard, a tolerance may be generated depending on the manufacturing environment. If such a tolerance occurs, as shown in FIG. 3, A clearance d may occur between the vehicle body 10 and the nozzle cover 400 when the cover 11 is shielded.

When the clearance d is generated between the vehicle body 10 and the nozzle cover 400, foreign matter may flow from the outside, or the position of the nozzle cover 400 may be fixed due to vibration or external impact generated when the vehicle is traveling The nozzle cover 400 may be broken and the nozzle 300 or the piston 200 may be damaged. Therefore, in the present invention, the tolerance can be compensated for minimizing the generation of clearances when the nozzle 300 and the nozzle cover 400 are coupled.
