Abstract

An alarm-protective device for avoiding user being clamped by vehicle window comprises a window driver, a pressure sensor and a sound alarm, wherein, the window glass is on the pressure sensor; the close contactor and open contactor of the touch switch of pressure sensor are connected to the driving circuit of window motor and the driving circuit of sound alarm. When foreign material is clamped between the window and the window frame, the pressure sensor works, the close contactor is cut off and the open contactor is closed, to stop the window and the sound alarm will sound. The invention canavoid the effects of sunlight, electromagnetic wave or the like, with low cost.

Description

technical field [0001] The invention relates to an alarm and protection device for avoiding being pinched by a car window, which belongs to the technical field of automobile accessory safety devices. Background technique [0002] When closing the window of the car, if there is a foreign object such as a hand on the top of the window glass, the rising window glass will clamp the foreign object between it and the window frame, and the window glass will continue to rise. Squeezing the foreign body will cause the foreign body to be damaged. Accidents of children's small hands, especially fingers, being pinched by rising car windows are common. Existing two kinds of car window anti-pinch protective devices. The first is an infrared detection protection device. When the car window is closed, it can detect whether there is any foreign object within the moving range of the window glass, and control the movement of the window glass according to the detection result: if there is a f...
