Electric safety window device and use method thereof

Abstract

An electric safety window device is disclosed. The device includes a doors and glass. A sliding cavity is arranged in the door. A sliding groove communicating with the outside is arranged at the rearend of the top wall of the slide cavity. A slide block is slidably installed up and down in the sliding cavity, the glass is slidably mounted in the sliding groove, the low end of the glass is fixedlyconnected with the slide block, a transmission cavity is arranged below the sliding cavity, a first rotating chamber is arranged below the transmission cavity, a first rotating shaft is rotatably mounted in the upper and lower end walls of the transmission cavity, the first rotating shaft is provided with a first rotating hole passing through the first rotating shaft vertically, the first rotating hole is provided with a second rotating shaft extending vertically, the upper end of the second rotating shaft penetrates the top wall of the transmission cavity and extends into the sliding cavity,the low end extends downward and is rotatably mounted in the bottom wall of the first rotating chamber, a first internal screw groove passing through the slide block is arranged in the slide block, and a first screw shaft extending upward and downward is threadably fitted in the first internal screw groove.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an electric safety window device and a using method thereof. Background technique [0002] Modern cars have higher and higher requirements for the comfort and convenience of windows, and electric windows have increasingly become a common configuration for cars. The so-called electric window is a device that drives the motor of the window lifter through the vehicle power supply to make the lifter move up and down, and drive the window glass to move up and down, so as to achieve the purpose of automatic opening and closing of the window. The electric window allows the driver or passenger to sit on the seat and use the switch to automatically lift the door glass, which is easy to operate and is conducive to driving safety. However, the traditional electric window device uses a sensor to detect the rotational speed of the motor shaft to prevent hands from being pinched. And so on, but the ...

Problems solved by technology

The electric window allows the driver or passenger to sit on the seat and use the switch to automatically lift the door glass, which is easy to operate and is conducive to driving safety. However, the traditional electric window device uses a sensor to detect the rotational speed of the motor shaft to prevent hands from being pinched. etc., but the production cost of this structure is higher, and for some low-priced cars, it will increase the overall car price
