Mechanisms for window lifts

Abstract

The invention discloses a mechanism for ascending and descending of a car window. The mechanism comprises glass (3) and a drive device. The drive device comprises a bracket (4), a first supporting block (5), a second supporting block (6), a vertical sliding block (7), a horizontal sliding block (8), a cylinder (9) and a motor (10). Guide columns (23) are arranged below the bracket (4), guide sleeves (24) are arranged on a door plate (1), and the guide columns (23) are sleeved with the guide sleeves (24). The bracket (4) is provided with a pressure sensor, and the second supporting block (6) is provided with a controller used for controlling the cylinder (9) to work. The pressure sensor is in signal connection with the controller, and the controller is connected with the cylinder (9) through signals. The mechanism for ascending and descending of the car window is stable in glass brake work and low in production cost.

Description

Technical field [0001] The present invention relates to the technical field of automobile safety, in particular to a mechanism for raising and lowering windows. Background technique [0002] With the rapid development of the automobile industry, electric lift windows have been widely used in various household vehicles. Only the buttons can be operated to control the lift of the glass on the door, and the operation becomes faster and faster. Among them, electric lift windows also have certain safety hazards. After pressing the up button, the glass on the door will rise quickly. If there is an obstacle on the path of the glass at this time, the obstacle will be crowded. Pressure and injury. Especially for children who are not sensible, it is very easy to put their limbs on the track of the glass, which can easily pose a threat to the safety of the child. There are also some anti-pinch devices in the prior art. These anti-pinch devices often use complex circuit diagrams to control...

AI Technical Summary

Problems solved by technology

Among them, the electric lift window also has certain potential safety hazards. After pressing the up button, the glass on the door will rise rapidly. If there is an obstacle on the track of the glass at this time, the obstacle will be squeezed damage by pressure

Especially for ignorant children, it is very easy to put their limbs on the trajectory of the glass, which is very easy to pose a threat to the safety of children

There are also some anti-pinch devices in the prior art. These anti-pinch devices often control the lifting and braking of the glass through complex circuit diagrams, but the stability of the complex circuit diagram is not good, that is, the anti-pinch devices are prone to brake failure; and The R & D and production costs of complex circuit diagrams are high, and it is not easy to popularize
