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

Embodiment Construction
[0013] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0014] Working principle of the present invention: as figure 1 As shown, when the glass on the bracket is resisted, and the resistance value is greater than the set value on the pressure sensor, the pressure sensor can send a signal to the controller, and the controller can drive the cylinder to work after receiving the signal, so that the pressure on the cylinder The telescopic rod shrinks, that is, the telescopic rod drives the horizontal slider to move to the left, so that the gear on the motor is separated from the linear rack, that is to say, the motor cannot drive the linear rack up and down normally; The push block on the top also moves synchronously with the telescopic rod (such as figure 1 As shown, the push block moves to the left), during the movement of the push block, the chute at the lower end of the push block can push the cylin...

The invention discloses a device for ascending and descending of a car window. The device comprises glass (3) and a drive device. The drive device comprises a bracket (4) connected with the glass (3), a first supporting block (5), a second supporting block (6), a vertical sliding block (7), a horizontal sliding block (8), an air cylinder (9) and a motor (10). A pressure sensor is arranged on the bracket (4), and a controller used for controlling the air cylinder (9) to work is arranged on the second supporting block (6). The pressure sensor is in signal connection with the controller, and the controller is in signal connection with the air cylinder (9). The device for ascending and descending of the car window is stable in glass braking work and low in production cost.
Description
technical field [0001] The invention relates to the technical field of automobile safety, in particular to a device for lifting and lowering vehicle windows. Background technique [0002] With the rapid development of the automobile industry, electric lift windows have been widely used in various household models, and only need to operate the button to control the lift of the glass on the door, and the operation becomes faster and faster. 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 pressure and damage. 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 the child. There are also some anti-pinch devices in the prior art. These anti-pinch devices often control the lifting and b...
