Foreign matter leakage-proof protection device for power window

Abstract

The invention relates to the technical field of power window equipment, and discloses a foreign matter leakage-proof protection device for a power window. The foreign matter leakage-proof protection device comprises a window frame body and a window body, wherein the window body is arranged between guide rails on the inner side of the window frame body and can slide up and down; a window fixing seat is arranged on one side of the upper part of the window frame body; a traction mechanism is arranged between the window fixing seat and the window frame body; a movable base is arranged below the window body, and one side of the movable base is fixedly connected with the traction mechanism; an anti-pinch transmission mechanism is arranged between the traction mechanism and a power driving mechanism; the window body is composed of a window frame and glass, and the window body is of an integrated bonding structure of the window frame and the glass; and the side plane of the window frame is flush with that of the glass. According to the foreign matter leakage-proof protection device, foreign matter can be prevented from falling into a transmission chamber of a precise and compact structure from a gap between the window body and the window frame body, so that the transmission structure is not clamped or damaged, and the sealing and safety performance of the power window can be further improved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle window equipment, in particular to a foreign body leakage prevention protection device for electric vehicle windows. 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. Electric windows allow the driver or passenger to sit on the seat, and use the switch to automatically lift the door glass. It is easy to operate and conducive to driving safety. It has become the first choice for the window design of various OEMs. In daily life and production equipment Wide range of ...

AI Technical Summary

Problems solved by technology

[0003] In the current use of electric windows, due to the sealing requirements of locomotives, the first generation of electric side windows has an outward pressing action after the movable window reaches the top. At the same time, the movable window adopts the installation of two aluminum alloy window frames to clamp the glass In this way, there is a gap of 1-2MM between the movable window frame and the glass, and a gap of 5-10MM between the movable window and the fixed window. In addition, the four corners of the movable window are rounded. During the actual use of the locomotive, There will be betel nut slag, cigarette butts, coal ash and other foreign matter intruding. Due to the synchronous belt and synchronous wheel transmission adopted by the electric side window, once the foreign matter is stuck, the movable window will fail and the motor will be blocked. Up and down movable window

[0004] Similarly, although the first generation of electric side windows has anti-pinch function on the electronic control, if the electronic components fail or the program has problems, the electric side windows will lose the anti-pinch function, and there will be certain safety hazards, so further work is needed.
