Description

Fixing member applied vibration suppression type wiper device and vehicle {Curb Vibration by adapting Fixing Member type Wiper System and Vehicle thereby}

The present invention relates to a wiper device, and more particularly, to a vehicle and a vibration-suppressing wiper device applied with a fixing member, in which the performance of wiping a rear window glass is greatly improved by reducing the generation of vibration in the operating direction of a blade.

In general, a wiper device for a vehicle includes a rubber blade that removes contaminants including water from the glass wiping surface of a window glass, a retainer that applies constant pressure to the blade to bring the blade into close contact with the window glass, and a motor that rotates the blade. It includes a wiper arm, and when the wiper arm is rotated by the operation of the wiper device, the rotating blade receives constant pressure from the retainer to secure the driver's view, and wipes the water off the glass wiping surface with a rubber material to form a thin water film.

Therefore, it is most important for the wiper device to reduce and maintain the frictional force on the window glass surface so that the rubber material of the blade uniformly forms a thin water film.

To this end, coating technology such as surface treatment or lubrication coating for reducing the blade friction coefficient is applied to the vehicle wiper device, and an injection molding method using precise dimensional management of the joint between the wiper arm and the blade or a separate fixing member is applied. The same vibration suppression technology as the fixing member application method is applied.

As a result, the wiper device to which the coating technology and the vibration suppression technology are applied can form a uniform thin water film even if the operator does not carefully manage the contamination of the oil film or foreign matter on the glass wiping surface.

Domestic Patent Publication No. 10-1998-021934 (June 25, 1998)

However, among the vibration suppression technologies, the method of applying the injection molding material increases the quality maintenance cost due to the size control of the injection molding product and lacks mass productivity, and the method of applying the fixing member is difficult to secure price competitiveness due to the cost of parts and additional assembly. It is vulnerable and inevitably brings about inhibitions on the design aspect. Moreover, in the case of the above fixing member application method, a separate fixing member is manufactured in a shape considering the blade shape and support so that a separate fixing member is installed inside the retainer at the top of the blade, and additional bolts for fixing with the retainer are added, thereby reducing parts cost as in the case of inevitable product performance. And it can be used only limitedly without considering the deterioration of price competitiveness due to the additional assembly cost.

In addition, the coating technology is affected by the increase in the number of operations of the wiper blade and the passage of time, so that the coating of the rubber of the blade is inevitably peeled off. There is a local difference in the friction coefficient of , resulting in non-uniformity. As a result, when the wiper device operates, the blade causes stick & slip phenomenon, which generates noise, vibration, and chattering, in which the blade shakes in the retainer.

In particular, the blade vibration phenomenon tends to occur more easily in a rear wiper device for a rear window glass than in a front wiper device for a front window glass. This is because in the rear wiper device, the blade side closer to the rotation axis of the wiper arm has a smaller rotation radius, so the rotation speed is relatively slow, resulting in increased friction. The formation of an uneven water film between the glass causes poor wiping, causing noise and obstructing the driver's rear view.

Accordingly, in the present invention, in consideration of the above points, in addition to the hinge part of the wiper arm rotating by the motor, the anti-vibration structure by mutual coupling of the retainer and the blade in the wiping direction is applied to points spaced apart in the blade length direction, thereby reducing the blade and retainer It simplifies the fastening structure, suppresses mutual vibration, and in particular, suppresses vibration by keeping the blade fixed by the anti-vibration structure, even in the limiting situation of the change in friction coefficient caused by wax and rubber wear of the blade due to durability during car washing. An object of the present invention is to provide a fixing member-applied vibration-suppressing wiper device and a vehicle in which window glass wiping performance is improved.

In a preferred embodiment, the protrusion on the blade side protrudes outward from the primary blade cover, and the retainer guide is composed of an inner surface of the retainer end not forming the separation distance. The blade-side protrusions are composed of left and right blade-side protrusions provided at the same position on the left and right sides outside the width section of the primary blade cover. A fitting tolerance serving as an assembly gap for coupling the primary blade cover and the retainer is formed on one of the protrusions on the left and right blades.

In addition, in order to achieve the above object, the vibration-suppressing type wiper device using a fixing member of the present invention includes a wiper arm, a flat blade cover in which a blade is inserted, a blade coupling part forming a detachable coupling structure between the wiper arm and the flat blade cover, A fixing structure for suppressing vibration of the blade consisting of a protruding vertical guide of the wiper arm at a rear position with a gap from the blade coupling unit includes a blade fixing unit formed with a gap at a rear position of the blade coupling unit to be
