Description

[Detailed description of the invention] This invention relates to a washer device such as a headlamp cleaner for a vehicle, and in particular to a washer for a vehicle that is configured such that the nozzle is stored inside the vehicle body when not in use and protrudes from the surface of the vehicle body when in use. Regarding equipment.

Washers, or cleaners, are attached to various vehicles, including passenger cars, to clean the headlights. Conventional examples of such cleaners are shown in Figures 1 to 3. It has been known.

That is, in the case of the washer device shown in the above-mentioned conventional example, the washer device is made of metal or resin and has a spout 1 at the distal end, a pipe 2 inside, and a fixing screw portion 3 and a hose connection portion 4 at the base end. A nozzle 5 is fixed to a bumper 6 with a nut 7, and a hose 8 is connected to this nozzle 5 to supply cleaning liquid in the form of a jet to wash away dirt from the lens surface 10 of the headlamp 9. (See Publication No. 55-142365).

However, in such conventional washer structures, the nozzle 5 is attached and fixed to the mounting part of the bumper 6 so as to protrude from the mounting part, so various restrictions are placed on the structure of these cleaners. Ta.

That is, in order to effectively clean the lens surface 10 of the headlamp 9, the height h of the jet nozzle 1 must be adjusted to the height H of the central axis O of the headlamp 9 as much as possible within a range that does not reduce the light distribution performance of the headlamp 9. It is necessary to make the distance l between the jet nozzle 1 and the headlamp 9 as large as possible in the longitudinal direction of the vehicle body, but if the cleaner is configured to meet such requirements, the cleaner will protrude from the surface of the vehicle body and become tall. However, the cleaner itself is easily damaged, its appearance quality is easily damaged, and pedestrians are easily caught and injured.

This invention was devised in view of the current situation, and its purpose is to attach the nozzle to a rotating bracket, rotate the rotating bracket by increasing or decreasing the water pressure in the tank, and then rotate the nozzle when in use. It is an object of the present invention to provide a vehicle washer device that can eliminate the above-mentioned conventional problems by having the nozzle protrude from the surface of the vehicle body and housed within the vehicle body when not in use.

This invention will be described in detail below based on embodiments shown in the accompanying drawings.

The embodiment shown in FIGS. 4 to 7 shows a case where this invention is applied to a head lamp cleaner device for a vehicle, and this head lamp cleaner device for a vehicle includes a nozzle 11,
A rotary bracket 14 is fixed by screwing the base end threaded portion 12 and a nut 13, and a vehicle body, that is, a bumper 15, which allows the rotary bracket 14 to rotate.
The flexible tank 17 has an upper surface stuck to the back surface of the bumper 15 and the back surface of the hinge 16.

The nozzle 11 is molded from metal, resin, or other hard material, and has a spout 18 formed at its tip, and a hose connection 19 at the tip of the base end of the nozzle 11, which has one end connected to the tank 17. The other end of the hose 20 is connected to the discharge port side of the nozzle 11 to supply cleaning liquid to the nozzle 11.

Further, as shown in FIGS. 4 and 7, the tank 17 has an orifice plate 21 erected therein. supplied,
When the liquid chamber 22 is full, the orifice passage 24
When the pressure inside the liquid chamber 25 exceeds a predetermined value, the cleaning liquid is supplied from the hose 20 to the nozzle 11 under pressure, and the cleaning liquid is supplied to the nozzle 11 from the hose 20.
8 to the lens surface 26 of the headlamp 27.

In the normal state, that is, when the headlamp cleaner device having such a configuration is not in use, the nozzle 11 does not protrude from the general surface of the bumper 15, that is, it is stored in the bumper 15, as shown in FIG. has been done.

In order to clean the headlamp from this state, when cleaning liquid is supplied into the tank 17 through the hose 23, as the liquid chamber 22 of the tank 17 becomes full of cleaning liquid, the hinge 16 is pushed upward and the rotating bracket 14 is moved to the third position. As shown in FIG. 6, the nozzle 11 rotates counterclockwise, and the nozzle 11 protrudes from the bumper 15 accordingly.

After that, when the cleaning liquid is further supplied into the tank 17, the cleaning liquid in the liquid chamber 22 is pressurized, and the pressure in the liquid chamber 25 becomes a predetermined value or more, and the cleaning liquid is supplied to the nozzle 11.
The lens surface 2 of the headlamp 27 is
A cleaning liquid is supplied to the lens surface 26 to wash away mud and the like adhering to the lens surface 26.

In addition, when the cleaning work is finished, the hose 23
Because the supply of cleaning liquid from tank 17 is stopped,

As a result, the nozzle 11 rotates clockwise due to its own weight until the nozzle 11 reaches the state shown in FIG.
stored within.

In the above embodiment, the case where this invention is applied to a two-lamp type headlamp is explained as an example, but this invention is not necessarily limited to this. By attaching a nozzle member, it is also possible to make the cleaner device compatible with a four-lamp headlamp.

As mentioned above, this device is designed so that when not in use, the nozzle is stored inside the vehicle body, and when in use, it is made to protrude from the surface of the vehicle body due to the pressure inside the tank, and the cleaning liquid is sprayed onto the object to be cleaned. In some cases, the nozzle does not protrude from the surface of the vehicle body, and as a result, it does not catch pedestrians while the vehicle is running, which not only improves the appearance quality, but also allows the nozzle to be made large during use. Therefore, the cleaning liquid can be sprayed from the optimal position for the object to be cleaned, such as a headlamp (for example, at approximately the same height as the center line of the headlamp), which improves the cleaning effect and prevents the nozzle from moving in or out of the tank. Since this can be done by increasing or decreasing the water pressure, the structure is simple and there are fewer failures.
