Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicular washer device, and more particularly to a vehicular washer device for improving the wiping performance when wiping with a wiper blade during vehicle traveling.

[0002]

[Prior art]

 Conventionally, a washer device using a windshield washer liquid has been used to wash dirt on the windshield glass. This windshield washer device is equipped with a washer tank, a washer pump, a nozzle, and piping such as a tube that connects these elements. The desired number of injection ports is formed in the nozzle of the washer device depending on the glass area of the windshield glass, the spray pressure of the washer liquid, the nozzle position, and the like.

Generally, the washer device is arranged at the rear side of the front body of the vehicle, which is the base end side of the wiper blade, and the landing point of the washer liquid is formed so as to be able to handle from the stopped state to the high-speed running state. Has been done.

For example, when the vehicle is stopped or running at low speed, the wiping range on the driver side and the wiping range on the passenger side are around 150 mm from the upper end and around 5 mm from the lower end, respectively. From the point, the wiper blade swings up from the point, and the washer liquid spreads over the entire wiping range to allow sufficient wiping.

[0005]

[Problems to be solved by the device]

 However, in general, the washer device has a preset landing point so that it can cope with the vehicle from a stopped state to a high-speed running state. In particular, when changing from a low-speed running state to a high-speed running state, as shown in FIG. 8, the influence of wind pressure and the like becomes larger than the jet pressure of the washer liquid, and the landing point gradually approaches the nozzle nozzle, The landing point, which had reached the stopped state or low-speed running state, will no longer be reached.

Therefore, even when the wiper blade swings, the washer liquid wipes only the base end side of the wiper blade, and cannot be wiped in a range where the washer liquid does not reach. In particular, in the wiping range on the driver side, the influence of wind pressure or the like is remarkable, and the washer liquid flows to the side end portion of the front windshield glass, which causes the inconvenience that it cannot be wiped at all.

As described above, in the conventional washer device, it is difficult to inject the washer liquid over the entire front windshield glass due to the distance from the glass surface and the number of nozzle holes, and the vehicle speed increases. There was the inconvenience that the injection point (the water contact point on the front windshield glass surface) was lowered.

An object of the present invention is to provide a washer nozzle for a vehicle in which the washer liquid reaches the wiping range of the wiper blade not only in the stopped state and the low speed running state but also in the high speed running state.

[0009]

[Means for Solving the Problems]

 A vehicle washer device according to the present invention is a vehicle washer device for injecting a washer liquid from a nozzle to a windshield glass, wherein the nozzle is arranged at a front position of a front body of the vehicle. In addition to the nozzle, it is preferable to dispose a second nozzle at a position behind the front body of the vehicle.

[0010]

[Action]

 According to the present invention, in the vehicle washer device that injects the washer fluid from the nozzle to the windshield glass, the stopped state and the low speed running state are determined by the nozzles arranged in front of the front body of the vehicle from the predetermined landing point of the windshield glass. Spray the washer fluid toward In the stopped state and the low-speed running state, the wind pressure of the air flow generated by the running of the vehicle is small, so that the injection of the washer liquid reaches a predetermined landing point.

Further, when the vehicle is at a predetermined speed or higher, the nozzle is disposed in the front position of the front body in which the speed of the airflow generated by the vehicle traveling is high, so that the washer liquid injected from the nozzle is diffused by the high-speed airflow. It becomes mist, then rides in the air current and lands on the entire windshield glass. In this manner, unlike the conventional washer device, the sprayed washer liquid is affected by the wind pressure and partially comes into contact with water, so that defective wiping does not occur.

Further, if a second nozzle is provided at the rear position of the front body of the vehicle in addition to the nozzle, the washer device similar to the conventional one is used by using the second nozzle in the stopped state and the low speed running state. Therefore, it is not necessary to inject the washer fluid from the front position of the front body far from the windshield glass. Therefore, in the stopped state and the low-speed running state, the injection pressure and the injection flow rate of the washer liquid may be the same as in the conventional case, so that the washer liquid consumption does not increase.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. The members, arrangements, and the like described below are not intended to limit the present invention and can be variously modified within the scope of the present invention.

1 to 5 show an embodiment of the present invention, and FIG. 1 shows a high-speed running state of an example in which a vehicle width lamp on a front fender and a nozzle of a washer device are integrated. 1 is a perspective view, FIG. 2 is an enlarged view of a main part of FIG. 1, FIG. 3 is an explanatory view for explaining the flow of the washer liquid in a stopped state or a low speed running state, and FIG. 4 is a flow of the washer liquid in a high speed running state. It is an explanatory view explaining.

In FIGS. 1 and 2, reference numeral 20 indicates a front windshield glass, reference numeral 21 indicates a hood as a front body, and a wiper blade is provided between the front windshield glass 20 and the hood 21. (Not shown) is provided, and the wiper blade is configured to slide the front windshield glass 20 to wipe the glass surface 22.

The washer device 10 of the present example shows an example including a washer nozzle integrated with a lamp. In this example, the washer device is provided as a lamp on both sides of the hood 21 on the upper side of the front of the vehicle. The injection port 13 of the washer device 10 is formed in the vehicle width lamp 11 for the vehicle width lamp 11. That is, as shown in FIG. 2, the washer device 10 is formed by opening the injection port 13 toward the inside (vehicle center side) at the mounting portion 12 of the vehicle width ramp 11. Further, the washer device 10 of this example is formed with the ejection port 13 facing upward. Reference numeral 14 is a washer liquid.

Further, in the present example, the windshield washer device 23 is also formed on the bonnet 21 on the base end side of the wiper blade as in the conventional case (see FIG. 3). The windshield washer device 23 of the present example is, as is well known in the art, in addition to the washer device 10, piping using a washer tank, a washer pump, a nozzle, a tube connecting each of these elements, etc. (Not shown).

Next, the operation of the embodiment having the above configuration will be described with reference to FIGS. 3 and 4. In the stopped state and the low speed running state, the washer liquid 14 is sprayed toward the front windshield glass surface 22 side by using the windshield washer device 23 as the second nozzle as shown in FIG.

As described above, the windshield washer device 23 is used in the stopped state and the low-speed running state in the same manner as in the conventional case, so that the washer fluid is removed from the front position of the bonnet 21 which is the front body far from the front windshield glass surface 22. Since it is not necessary to inject 14, and the injection pressure and the injection flow rate of the washer liquid 14 can be the same as in the conventional case, the consumption amount of the washer liquid does not increase.

In the example of FIG. 3 described above, only the windshield washer device 23 as the second nozzle is used, but even if the washer device 10 is used, the wind pressure of the air flow generated by the vehicle running is increased. Since the water content is small, it is possible to reach a predetermined landing point on the front windshield glass surface 22 even by the injection by the washer device 10.

Further, when the vehicle is traveling at a high speed (predetermined speed: 60 km / h when the speed is equal to or higher than a predetermined speed), as shown in FIG. 4, the washer device 10 located at the front position of the vehicle has a high air velocity. Since the vehicle position is liable to be changed, the washer liquid 14 injected from the injection port 13 is diffused into a mist by the turbulent flow, and the mist-like washer liquid 14 having a reduced weight flows on the front of the air flow. The entire surface of the windshield glass surface 22 is exposed to water.

As described above, the washer liquid 14 is jetted from the nozzle arranged in front of the hood 21 of the vehicle, diffused by the turbulent flow, and can be sprayed on the entire front windshield glass surface 22 by being carried on the airflow. Unlike the washer device 23, the jetted washer liquid 14 is affected by the wind pressure to partially land on the water, and a defective wiping does not occur.

As described above, since the washer liquid 14 can be diffused by the turbulent flow in the high-speed traveling state, the nozzle of the washer device 10 is not limited to the spreading nozzle in the above embodiment.

FIGS. 5 to 7 show other examples of the present invention. In this example, the same members as those in the above-described embodiment are designated by the same reference numerals, and the description thereof will be omitted. FIG. 5 shows another example, and is an enlarged perspective view of an essential part viewed from the driver's seat side. In the embodiment of FIGS. 1 to 4, the washer nozzle is formed in the mounting portion 12 of the vehicle width ramp 11, but in this example, the vehicle width ramp 11 on the front fender and the washer device 10 are integrated. It was done. Further, although the diffusion nozzle is used as the nozzle of the washer device 10 in this example, the invention is not limited to the diffusion nozzle.

That is, in this example, the vehicle width lamp 11 on the right side when viewed from the driver's seat side is shown, and the spreading nozzles 16 and 17 are located on the inner side (vehicle center side) and the driver's seat side, and the injection port 13 of the nozzle. Is arranged so as to face upward. According to this structure, the lamp and the nozzle are integrated, and it is possible to prevent the nozzle from freezing due to the heat generated by the lamp itself in a cold region.

FIG. 6 shows an example in which the emblem 18 of the front body and the washer device 10 are integrated. This example shows an example in which the diffusion nozzles are arranged at the respective diagonal positions of the emblem 18 whose upper side has two diagonal sides.

As described above, if the washer device 10 is integrated with the vehicle width lamp 11 and the emblem 18, the appearance is improved. In addition, the washer nozzle is arranged on the base end side of the wiper blade, which eliminates the limitation of the conventional design of the washer nozzle, and the degree of freedom in design can be sufficiently ensured.

FIG. 7 shows an example in which a washer device is formed at the upper end of the connecting portion of the bush guard 19 of a four-wheel drive vehicle. As in this example, a 4WD or rally car that is likely to get mud and sewage may be installed on the bush guard (kangaroo bar) 19 as shown in FIG. 7.

[0029]

[Effect of device]

 As described above, according to the present invention, in the stop state and the low speed running state, the washer liquid is jetted from the nozzle arranged in front of the front body of the vehicle toward the predetermined landing point of the windshield glass, It is possible to reach a predetermined landing point. Further, when the vehicle speed is higher than a predetermined speed, the nozzle is located in front of the front body where the speed of the air flow generated by the vehicle is fast, so the washer fluid injected from the nozzle is diffused by the fast air flow and is fogged. After that, it rides in the air current and lands on the entire windshield glass. And unlike the conventional washer device, since the entire surface of the glass can be sprayed, the cleaning property is improved.

As described above, the spray of the washer liquid can be kept away from the influence of the vehicle speed, and the wipe range of the glass surface can be obtained even when the vehicle is in a stopped state, a low speed traveling state, a high speed traveling state or the like. The whole can be washed. Further, unlike the conventional washer device, the sprayed washer liquid is affected by the wind pressure and partially comes into contact with water, so that defective wiping does not occur.

Further, if a second nozzle is provided at a position behind the front body of the vehicle in addition to the nozzle, a washer device similar to a conventional one is used by using the second nozzle in a stopped state and a low speed traveling state. Therefore, it is not necessary to inject the washer fluid from the front position of the front body far from the windshield glass. Therefore, in the stopped state and the low-speed running state, the injection pressure and the injection flow rate of the washer liquid may be the same as in the conventional case, so that the washer liquid consumption does not increase.
