Description

  The present invention relates to a turbulence plate device for a wiper, and more particularly, to a turbulence plate device for a wiper that reduces wind resistance, prevents vibration during wiping, and has a high wiping effect for rainwater.

  Generally, when a wiper of an automobile performs a wiping operation during traveling, the entire wiper is simply fixed by a wiper arm. Therefore, when the vehicle speed is different, the wind effect affects the wiping effect of rainwater. Therefore, a structure as shown in FIG. 1 is provided, in which a long turbulent plate 101 is extended from the front edge of the wiper 10, and the wiping operation is stabilized by the turbulent plate 101. . However, when the wiper 10 wipes upward along the windshield 20, the wind is normal, and when the wiper 10 is downward, the wind is reverse. Therefore, the wiper 1 having such a single-sided force (wind resistance) vibrates at the time of lower pressure. It has a phenomenon, and generates an unstable situation especially at high speed running.

  The main object of the present invention is to provide a kind of turbulence plate device of wiper, which has a structure capable of reducing wind resistance of the wiper, preventing generation of vibration, and stabilizing the wiping operation. Shall be.

The invention of claim 1 is a turbulent plate device for a wiper provided on a first frame, a second frame, a third frame, and a wiper formed of rubber.
The front and rear turbulence plates are extended in front of the first frame and the rear bottom edge so as to be inclined downward, and the front turbulence plate is formed into a piece having arcuate ends at both ends, and has a substantially S-shaped surface. It is formed in a wavy shape, and a downward bent portion is provided at the front edge, and large and small slots having different lengths are provided at a connection portion of the rear edge of the front turbulence plate with the first frame, and openings are provided at both ends. Is provided, a downward bent portion is provided at the long edge and the opening edge of the large and small slots and the opening, and a forward horizontal bent portion is provided at the bottom edge of the first frame located at the large slot. The rear turbulence plate has a low center, slightly raised at both ends, and a downward bent portion formed at its outer edge.When the wiper performs a wiping operation, the wind pressure in front forms pressure along the front turbulence plate. , And flows downward from the large and small slots at the trailing edge to prevent the formation of resistance. Formed, characterized by a smooth and Kosu拭 to prevent vibration of the wiper, and a wiper turbulence plate apparatus.
According to a second aspect of the present invention, in the turbulence plate device for a wiper according to the first aspect, a forward-facing horizontal bent portion is formed at a bottom edge of the first frame located in the long hole of the front turbulence plate. The turbulence plate device of the wiper is characterized in that wind force is quickly raised by the horizontal bent portion to reduce wind resistance.

  The wiper turbulence plate device of the present invention is provided with a front and a rear turbulence plate on the wiper, and a corrugated surface and a bent portion of the front and rear edges on the front turbulence plate. The wind resistance is reduced, the vibration is prevented, and the wiping operation is stabilized. Therefore, it can be said that the present invention is a device having practicality and novelty.

  The turbulence plate device of the wiper of the present invention is provided with a front turbulence plate in front of the frame of the wiper, before being stretched downward at the rear bottom edge, and a rear turbulence plate. The leading edge is bent downward, the trailing edge is provided with slots of different lengths, the slot edge is bent downward, the turbulence plate is low at the center and slightly raised at both ends, and its outer edge is facing downward When it is bent and the wiper performs the wiping operation, the wind pressure in front forms pressure along the front turbulence plate and flows downward from the long hole of the trailing edge, preventing the formation of resistance and preventing the turbulence The plate forms reinforcement ribs to prevent deformation of the frame and to generate turbulent downward pressure to stabilize and smooth the wiper operation.

  As shown in FIGS. 2, 3 and 4, the present invention is provided on a wiper 100 composed of a first frame 1, a second frame 2 and a third frame 3, and a rubber strip 6. The front and rear turbulence plates 4 and 5 are provided at the front and rear bottom edges so as to be inclined downward, and the front turbulence plate 4 has both ends in the form of a piece having an arc angle, and the surface thereof has a substantially S shape. And a downward bent portion 41 is provided at the front edge, and large and small long holes 42 and 43 of different lengths are provided at the connection portion of the rear edge of the front turbulence plate 4 with the first frame 1. The opening 44 is provided at both ends, and the large and small slots 42, 43 and the long edge and the opening edge of the opening 44 are provided with downward bent portions 421, 431, 441 and located at the large slot 42. A horizontal bent portion 11 facing forward is provided at the bottom edge of the first frame 1.

  The post-turbulence plate 5 has a low center, slightly raised ends at both ends, and a downward bent portion 51 formed at an outer edge thereof.

  Due to the combination of the above-described components, when the wiper performs the wiping operation, the front wind pressure forms a pressure along the front turbulence plate 4, and further flows downward from the large and small long holes 42 and 43 at the trailing edge, thereby reducing the resistance. The formation of force is prevented, the wiper is prevented from rising due to the wind, the rear turbulence plate 5 forms a reinforcing rib, and the first frame 1 is prevented from being deformed during the wiping operation, and is also subjected to the wind. When the wiper 100 performs a wiping operation by forming a downward pressure on the turbulent plate, a downward pressure balanced by the front turbulent plate 4 and the rear turbulent plate 5 on both sides is generated to stabilize the wiping operation, Enhances the effect of wiping. FIG. 5 shows the operation of the present invention. When the wiper 100 performs the wiping operation along the windshield 20, the surface of the front turbulence plate 4 of the wiper 100 has a wavy shape, and the large and small long holes 42, 43 are provided with the bent portions 421, 431 to conduct the flow. When an effect is formed and the forward wind passes through the pre-turbulence plate 4, it first builds up pressure at the wavefront and flows more rapidly downwards from the large and small slots 42, 43 at the trailing edge, creating another resistance. Preventing formation, the horizontal bent portion 11 at the bottom edge of the first frame 1 rapidly raises the wind, the central portion of the first frame 1 is higher than other positions, and the bent portion 11 guides the wind upward. Thus, the wind resistance is reduced and the wiper 100 does not generate vibration. The rear turbulence plate 5 forms a reinforcing rib and turns the wind upward after the pressure is reduced by the wind, thereby preventing the deformation of the first frame 1 at the time of the wiping operation. During the wiping operation of the wiper 100, the downward pressure is balanced on both sides to stabilize the wiping operation and enhance the wiping effect of rainwater.
