JPH0592014U - Auto wiper stand - Google Patents

Abstract

(57) [Summary] (Corrected) [Purpose] To prevent the wiper plate from adhering to the windshield during extreme heat. [Structure] A joint part 1 is provided in a part of a wiper blade assembly, a shape memory alloy 2 is fixed to this part, and the blade is pulled out from the wind glass in extreme heat. When using a wiper, the shape memory alloy is cooled with a washer liquid to bring the blade into close contact with the window glass.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This utility model relates to a wiper stand that separates an automobile wiper from a glass surface by using a shape memory alloy.

[0002]

[Prior Art]

 In the past, there was a wiper stand for cars, but when the rain stopped, the stand had to be set up again.

[0003]

[Problems to be solved by the device]

 This invention does not have to manually operate the wiper stand that prevents the rubber of the automobile wiper from melting and sticking to the glass surface, but automatically using the heat of the sun.

[0004]

[Means for Solving the Problems]

 This invention was made in order to eliminate the drawback. To explain it, the temperature at which the shape memory alloy is restored is made slightly lower than the temperature at which rubber is attracted, and the shape memory alloy is applied to a glass wiper. The shape memory alloy is attached to the part of the joint with a spring attached to press it so that the wiper will go up a little when restored.

[0005]

[Action]

 With this device, when the glass becomes hot on a sunny day, the wiper moves up due to the restoring force of the shape memory alloy, and when it rains, the shape memory alloy cools and sticks to the glass surface.

[0006]

【Example】

 Hereinafter, embodiments of the present invention will be described. By attaching the present invention to the joint part of the wiper, it is possible to prevent the glass surface from being heated by the heat of the sun and melting and sticking of the rubber. Also, if you want to apply the wiper even on a sunny hot day, you should first apply the washer liquid, so if you pass the washer liquid through the shape memory alloy, the shape memory alloy will cool and will be attached again to the glass surface. You can make it happen.

[0007]

[Effect of the device]

 By heating the automobile wiper with the heat of the sun, it can be automatically separated from the glass surface.
