Car wiper automatic lift system
[21] The present invention relates to a vehicle wiper that is installed on the windshield of the vehicle in order to secure the driver's vision in the snow or rainy weather. In particular, in the rain without the driver's separate operation, the wiper is brought into contact with the glass surface and normally used when not in use. The present invention relates to a vehicle wiper automatic lift device capable of preventing damage to the wiper rubber blade by automatically separating the wiper rubber blade from the glass surface.
[22] As the wiper for automobiles has a rubber blade installed on the wiper pressed against the surface of the glass, the rubber blade causes adhesiveness to the glass surface according to the surrounding environment such as solar heat due to the rubber's unique cohesiveness. When the driver starts to use the wiper as it sticks together between the glass surface and the wiper rubber blades, the rubber blades stuck on the glass surface are momentarily separated by the wiper operating force, which hurts the delicate rubber blade and uses the wiper in rainy weather. In case of unsmooth rubber blades, the driver's vision has been hindered, and the hassle and expense of rubber replacement are often a problem.
[23] In order to solve this problem, the wiper arm is raised and stored when the vehicle is standing up, and the wiper arm is lowered when the vehicle is in operation. It prevents the blades from contacting the glass surface and prevents small scratches on the wiper rubber blades and extends the life, and it is a means to have a clear view when using the wiper in rainy weather, especially in the tropical countries. It is becoming.
[24] However, the method as described above may be a method for protecting the rubber blade, but the user has to raise and lower the wiper by hand every time, which is not a convenient method for many drivers.
[25] The present invention was devised to solve the above problems, and when the wiper does not operate, the driver does not need any separate action, and also does not use a power source, and the wiper arm (ARM) is separated from the glass surface and the rubber blade. Raise as much as possible to avoid contact between the wiper rubber blade and the glass surface, and during the wiper operation, the push spring of the device's operating device, which is holding the wiper arm by the wiper operating force, enters the operating device momentarily. The wiper rubber blade, which is separated from the glass surface, returns to its original position to clean the surface of the glass as it comes into contact with the glass surface to protect the rubber blade of the wiper and also contributes to the driver's safe operation. It is an object of the present invention to provide an automatic lift device.

[26] Specific configurations and operations of the present invention will become more apparent from the following description.
[27] 1 is an overall configuration diagram of the present invention, Figure 2 is an assembled cross-sectional view of the operating tool of the present invention, the push spring 10 inserted in the piston rod 9 of the device is pushed out of the operating body (1) I'm in a state.
[28] 8 is a state in which the wiper rubber blade 16 is spaced apart from the glass surface 17, the push spring (10) built in the device is pushed out of the operating body (1) to push up the wiper arm (18) It is a reference figure which shows the state in which the rubber blade 16 was spaced apart from the glass surface 17. FIG.
[29] According to the present invention, the fixing bracket 12 is mounted at a position spaced apart by the stroke distance of the piston 7 from the center of the wiper rotary shaft 15, and one end of the tension wire 11 is mounted on the fixing bracket 12. , The other end is fixed to the center bent portion of the piston rod (9).
[30] The actuator body 1 is fixed to the middle of the wiper arm 18 using screws.
[31] When the wiper arm 18 operates to move upward in FIG. 6, the wiper arm 18 pulls the tension wire 11 connected to the actuating body 1 fixed to the wiper arm 18 and consequently the piston 7. Is pulled backwards, causing the fluid to be sucked into the front of the piston (7) through the intake hole drilled in the piston (7), and the piston (8) is inserted by the force of the piston spring (8) inserted at the rear of the piston (7). 7) generates pressure on the fluid entering the front of the piston (7), the suction rubber valve (4) is to block the inlet of the piston (7).
[32] In addition, the piston (7) in the operating body (1) is to apply pressure to the fluid by the restoring force of the piston spring (8) inside, the fluid under pressure through the outlet (5) is finely adjusted Slowly exit the piston (7) to the rear end so that the piston (7) to return to the original position at a slow speed, at this time the length of the length of about 1/3 of the stroke distance of the piston (7) operating body as shown in FIG. (1) Piston ring when the piston (7) returns from (P) to (F) by making the front side (F) of the inner cylinder wall larger than the rear side (P) as well as larger than the diameter of the piston ring (6). The section where 6 is pressed against the inner wall of the cylinder returns slowly, and when the inner diameter of the inner wall of the actuator body 1 reaches a large portion, the fluid quickly exits behind the piston 7, so that the piston 7 starts from the original position. Up to the position, there is no resistance of the internal pressure fluid. Rapidly, the ever constructed will return to the strong force, which give me up for the wiper again.
[33] In addition, the push spring 10 inserted into one side of the piston rod 9 is configured to move together with the piston 7 by being integrally formed with the piston 7, and the push spring 10 is operated by the main body ( 1) Since it moves along the guide hole 19 configured on one side, when the piston 7 is in the original position, one end of the push spring 10 is perpendicular to the direction of movement of the piston 7, as shown in FIG. 2. To the wiper arm 18 as it is pushed out in the direction of () and exposed from the actuating body (1), and the piston (7) is pulled in and along the guide hole (19) into the actuating body (1). Since the actuator body 1 is fixedly mounted, the wiper arm 18 is lifted by the end of the push spring 10, and the push spring 10 enters the actuator body 1, and at the same time the glass surface ( It will come down to 17).
[34] Further, as shown in FIG. 9, the guide body 1 is upwardly coupled to the glass surface 17 so that the push spring 10 raises the wiper arm 18, but the tension wire 11 connected to the piston rod 9. By connecting the end of the to the flange 20 spaced apart closely to the wire axis of rotation 15,
[35] When the wiper arm 18 rotates, the tension wire 11 is pulled by the rotation radius thereof, and when the tension wire 11 is pulled, the piston rod 9 connected to one end thereof is pulled out, so that the guide body 1 May be configured to operate the piston 7 and the push spring 10 therein by the wiper arm 18 being rotated in a fixed state.
[36] Therefore, the present invention eliminates the inconvenience of the driver lifting the wiper arm 18 to protect the wiper rubber blade 16. When the wiper arm 18 stops in the right position after the wiper is used, the piston 7 The distance between the wiper rubber blade 16 and the glass surface 17 is spaced apart by automatically pushing up the wiper arm 18 at a time difference by about a slow moving time (about 10 seconds to 30 seconds).
[37] According to the present invention having the above configuration, the wiper rubber blade and the glass surface contact the normal position when the wiper is used without using the power supply without the need of the driver's separate operation, and when the wiper stops at the original position without using the wiper, the wiper It protects the wiper rubber blade by automatically separating the contact between the rubber blade and the glass surface, so that it is very useful for the driver's clear view in rainy weather.
