Abstract

When the vehicle wiper blade is not normally used, the rubber tip of the blade is inclined in one direction due to a long fixed contact with the glass surface (Fig. 2-2). When the deformed wiper blade is operated, the shaking phenomenon and noise are generated when the blade moves in the deformed direction while reciprocating the glass surface. In this case, if the straight direction of the wiper blade is rotated 180 degrees by simple operation (Fig. 1), the direction of the deformed rubber tip of the blade is reversed, resulting in first aid effect, eliminating vibration and noise, and keeping the wiper blade normally fixed. By changing the direction of rotation from time to time to prevent deformation in one direction can also extend the life of the wiper blade.

Description

Vehicle wiper blade connection structure that can be rotated {Automobile rotate wiper}

When the vehicle wiper blade is not in use, the fixed position with the glass surface is the same, and if it is in contact for a long time, the blade will be inclined in one direction (Fig. 2-2), which will cause the wiper to shake (Fig. 3- 5) and noisy unpleasant noise is generated and wiper life is shortened. In this case, the rain on the front glass of the vehicle is not properly wiped when it rains, which makes it difficult for the driver to secure a vision and may cause driving accidents, resulting in a traffic accident.

To solve this problem, the wiper can be rotated 180 degrees by a simple operation of the driver so that the direction of contact of the blade is not fixed only to one side for a long time. By changing the direction of the contact surface from time to time it is a rotation device of the wiper to prevent the deformation of the rubber contact surface of the blade inclined in one direction and smooth operation of the wiper. In addition, the operation of the wiper is not smooth, and even when an abnormal phenomenon occurs, the wiper is rotated to make the first aid effect smoothly.

1. Bracket A and Bracket B, which connects the wiper blade (Fig. 1-17) to transfer the reciprocating motion from the wiper blade and the vehicle engine bone net, are divided into two parts, bracket A and bracket B as shown in Figs. 4-18 and 4-19. Dividing this, as shown in Fig. 4-10 to form a rotation axis (Fig. 4-10) in the center of the bracket A and through this to the center of the bracket B to fasten by coupling the pressure spring (Fig. 4-11).

2. Use the elastic force of the pressure spring to fix the bracket of the above coupling type, and form the fixing hole of Fig. 4-12 with the protruding fixing pin of Figs.

3. The above-mentioned 1, 2 combined wiper blade of the completed form is inserted into the engaging ring at the end of the moving table of Figure 1-17 to be used.

4. The use of the above combined wiper is to hold the bracket A (Fig. 4-18) and Bracket B (Fig. 4-19) with each other by using both hands and pull in the opposite direction to pull out the protruding fixing pins of Fig. 4-9. After turning away from the fixing hole of Figs. 4-12 and rotating 180 degrees, the fixing pin 4-9 is inserted into the fixing hole 4-12 to fix it.

The rotary wiper blade of the present invention prevents the tip of the blade from being deformed in only one direction due to prolonged contact with the glass surface of the existing vehicle wiper blade, and the wiper is turned by turning the wiper as an emergency measure in the event of a wiper abnormality. It can contribute to safe driving and traffic accident prevention by ensuring smooth operation of the wiper and ensuring the life of the wiper and securing the driver's vision.

Claims (1)

Two brackets (Fig. 4-18, divided into lower and upper parts) to enable rotation in the long direction about the bracket in the connecting bracket that connects to the movement table (Fig. 1-17), which rotates in the wiper blade. Fig. 4-19) to secure the rotary shaft (Fig. 4-10) and to fasten the elastic pressure spring (Fig. 4-11) so as to have a fixed force, the upper bracket (Fig. 4-18) and the lower bracket (Fig. 4-19) The wiper blade is rotated about the axis of upper and lower brackets in the form of a fixing hole (Fig. 4-12) and a protruding fixing pin (Fig. 4-19) which are fitted and fixed to both sides. The devising of the connection structure of this possible vehicle wiper blade.
