JPS60139556A - Parallelly movable type electric windshield wiper - Google Patents

Abstract

PURPOSE:To widen a visual field of a windshield, by making a wiper arm wipable as being shifted on a glass surface in a state of being slidden thereon simultaneously with movements of a linear motor in both directions. CONSTITUTION:A bow-shaped guide rail 3 being accorded with the curved surface form on a windshield is horizontally installed sideways with a screw or the like and locked thereto. And, under a state of being contacted close to the guide rail 3, a linear motor 4 connecting a power source to an electric mechanism inside a car body is installed in a horizontal form in both directions free of slide motion. A sponge or synthetic rubber wiper arm 6 is attached lengthwise to a lower side part 5 of the linear motor 4 and locked thereto.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a parallel movable wiper that reciprocates from end to end over the glass surfaces of the windshield and rear window of an automobile.

In modern times, advances in cutting-edge technology have led to remarkable advances in industrial development, and competitive development of superior new products is being carried out day and night in all fields.

The automobiles according to the present invention range from long-distance transportation vehicles that support key industries, to delivery vehicles that serve as local transportation, to buses that transport people,
Along with the development of industries such as taxis and private cars, the number of vehicles has increased significantly year by year, and cars have now become an indispensable part of daily life, forming an era of motorization. .

However, on the other hand, the number of car accidents is increasing year by year, and tragic accidents are being reported in daily newspapers, television, radio, etc. from all over the country, and it is commonly known as the traffic war. It has become a social problem.

Graphically, the highest number of these accidents occur when driving in the rain, especially when visibility is poor, and the severity of the accidents is said to be far more dangerous than when driving on clear skies due to factors such as the Hydro-7 laning phenomenon. ing.

The best way to prevent accidents like this is to ride in conditions with good visibility and keeping a careful eye on what's ahead.

It is said to be particularly difficult to drive under bad conditions, especially when it is snowing or raining.
Up until now, which is said to be the 1980s, no major improvements have been made to wipers, and it is clear that they are lagging behind and are unable to take advantage of the benefits of technological innovation.

With the conventional wiper function, you can see only the part that rotates about half a turn in a fan shape, but it is extremely difficult to see beyond that area, especially when driving in the snow, as lightning may accumulate on the glass surface. The driver is now forced to drive in an extremely dangerous manner, with only the part that has been wiped away by the wipers visible.

Focusing on the above-mentioned reasons, the present invention has been developed as a result of extensive research and development, and as a result of extensive research, the present invention is an epoch-making mobile device that allows you to see almost the entire area of the windshield, etc., even in snowing or raining conditions. It was created in the type wiper, and was developed with a view to its success.

An embodiment of the present invention that achieves the above object will be described below with reference to the drawings.

The rear window has the same structure as the windshield, so its explanation will be omitted.

As shown in the figure, an arcuate guide rail 3 that matches the curved shape of the windshield is attached along two sides of the vehicle window frame located at the upper end of the front windshield surface 1 of the vehicle body using screws or the like. horizontally and horizontally. and,
In contact with the guide rail 3, a linear motor 4 whose power supply is connected to an electric mechanism inside the vehicle body is mounted horizontally and slidably in the left-right direction.

The linear motor 4#i' forms the main part for the purpose of the present invention, and is attached to the lower side part 5 of the linear motor container.
A sponge or synthetic rubber wiper rod 6 with a length equal to the width of the glass surface is fixed vertically in close contact with the windshield surface, and the power source is connected to the vehicle body. The present invention is constructed by connecting internally to the wiring of an electric mechanism that has been provided with a switch function in advance.

The present invention configured in this manner is such that when the on/off switch inside the vehicle body is input, the self-motion of the linear motor 4 allows the linear motor 4 to slidably come into contact with the guide rail 3 which is placed in a horizontal position. Continuously reciprocate in the left and right direction.
The wiper rod 6 fixed perpendicularly to the lower side 5 of the linear motor container can wipe the windshield surface 1f in a sliding state from end to end. Therefore, it can wipe a wide area without leaving any residue.

In addition, regarding the speed of wiping movement, this linear motor does not require complicated conversion functions such as gears, belts, chains, etc., so you only need to adjust its increase/decrease function, so it is the most suitable speed that does not interfere with driving. There is no argument that it is better to serve it with a focus on speed.

υAs mentioned above, the present invention has a characteristic that maintenance and inspection are extremely easy due to its simple structure.Since the vertical wiper rod is configured to slide completely from end to end, it can be easily used in the rain. Even under bad conditions such as snowfall, it is possible to wipe almost the entire surface, so a wide field of view can always be obtained, and high reliability is something that cannot be missed these days. It is an extremely high level of contribution and has an immeasurable and meaningful effect.

[Brief explanation of the drawing]

FIG. 2 is a front view of a drawing vehicle body, showing a state in which the parallel movable wiper of the present invention is mounted on the windshield surface. E car body. 1-70 glass surface, 2-window frame, 3-guide rail,

Claims (1)

[Scope of Claims] A wiper for wiping away snow, raindrops, and water films adhering to a windshield and a rear window of a vehicle body, the wiper comprising a guide rail that matches the curved shape of the windshield or rear window and is arranged horizontally and horizontally. A linear motor is attached to the window frame at the top of the glass surface, and a linear motor that freely slides left and right in contact with the guide rail is installed. By attaching and fixing the wiper rod vertically to the lower side of the near motor container in close contact with the windshield surface, etc., the linear motor can be moved in the left and right directions. A parallel movable wiper characterized in that the wiper rod is simultaneously moved in a sliding manner on the glass surface while wiping the glass surface.
