Description

Separated length variable wiper for car

The present invention relates to a variable-length wiper for a detachable vehicle, and more particularly, to a variable-length wiper for use regardless of vehicle type. That is, the present invention relates to a variable-length wiper for a detachable vehicle that can be used simultaneously for several vehicle types by varying the length of the wiper blade.

In general, when driving a vehicle in the rain, wipers are used on the front and rear to secure visibility. Such a wiper is composed of a wiper blade for wiping the glass surface of the vehicle, and a support and an arm for supporting the wiper blade.

Here, the wiper blade is usually made of a soft rubber material to remove rainwater on the glass surface by pushing it to the edge.

At this time, the higher the pressure that the wiper applies to the glass surface, the better the rainwater can be removed, so research on increasing the pressure of the wiper has been continued.

As an example, in Korean Patent Laid-Open Publication No. 10-2006-0117127, a system for regulating the pressing pressure of an automobile wiper device that can automatically control the wiper pressing pressure according to the change in the current of the wiper motor was studied.

However, even in this case, there is a disadvantage in that it is difficult to remove rainwater in areas with a large change in the radius of curvature of the glass surface, such as a passenger seat.
