[0002]

2. Description of the Related Art Conventionally, most vehicle bumpers mounted horizontally on the front and rear parts of a vehicle are made of steel (especially large vehicles such as buses and trucks). Recently, in addition to steel products, the number of products integrally formed of synthetic resin is increasing, and they have many excellent characteristics as compared with steel products. Such a vehicle bumper made of synthetic resin can be molded by blow molding.

By the way, recent automobiles are provided with a device for spraying a cleaning liquid onto the windshield to wash out dust and dirt adhering to the windshield, wipe off dirt with a wiper, and secure the visibility. With this device, by traveling on unpaved roads,
The dust and dirt on the windshield can be removed to ensure visibility, which can greatly contribute to safe driving.

[0004]

However, when driving on rough terrain, on construction sites, or on unpaved roads, not only the windshield, but also the headlamps become dusty and the illumination is disturbed, resulting in insufficient illuminance. , Very dangerous. In particular, industrial vehicles such as trucks often travel on construction sites and unpaved roads, and countermeasures have been required. Therefore, as with the windshield, there has been considered a cleaning means for rinsing dust adhering to the surface, that is, a means for spraying a cleaning liquid onto the headlamp to wash it away.
However, it has been a problem whether a sufficient space for providing such cleaning means can be secured. The present invention has been proposed in order to improve such inconvenience, and an object thereof is to provide a bumper equipped with a vehicle headlamp cleaning means capable of effectively cleaning the headlamp.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is a hollow vehicle bumper formed by blow molding, which is mounted horizontally at the front of a vehicle and has a headlamp. A head tank cleaning liquid tank with a partition is provided in the internal space near the tank, and a liquid injection port is formed on the bumper upper surface at the position of this liquid tank so that it can be attached to and detached from this liquid injection port. The lid member is a hollow body, and the lid member is connected to the liquid tank by a pipe for liquid supply, and the liquid in the liquid tank is supplied to the lid member by a pump. It is characterized in that a guide pipe for a liquid guide directed to the headlamp is provided so as to project and a nozzle is formed at a tip of the guide pipe.

[0006]

The lid member can be removed from the liquid injection port and the cleaning liquid can be injected into the liquid tank in the bumper. When the pump is operated, the cleaning liquid is sent from the liquid tank into the lid member through the pipe. Then, the inside of the lid member is gradually filled with the washing liquid, and the washing liquid is sprayed onto the headlamp from the nozzle at the tip through the guide pipe at the top of the lid member, and the dust on the surface of the headlamp can be washed away.
