[0002] Modern cars have higher and higher requirements for the comfort and convenience of car windows, and electric windows have become more and more common in cars. So-called electric windows are devices that drive the glass lifter motor through the vehicle power supply to make the lifter move up and down, driving the car window glass to move up and down, achieving the purpose of automatic opening and closing of the car window. Intelligent anti-pinch automobile window rocker has been widely used in modern cars and has become an important part of the car window system.

[0003] The working principle of the intelligent anti-pinch automobile window rocker is to install a Hall sensor or other type of sensor on the window rocker motor. When the window is rising, if the sensor detects that the motor speed is abnormally slow or the window encounters an obstacle, it will immediately send a signal to the car's electronic control unit. The ECU determines whether to perform an anti-pinch operation based on the received signal. However, the existing anti-pinch mechanism of the automobile window has the following shortcomings.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, as shown in the attached document Figure 1 -Appendix Figure 5 As shown, this utility model provides a technical solution: an intelligent anti-pinch car window rolling actuator, including a frame 1, a window rolling motor 2, a fork arm assembly 3, and a glass window 4. A connecting block 41 is fixedly connected to the bottom of the glass window 4. The bottom end of the glass window 4 is installed inside the base 5. A buzzer 52 is fixedly installed on the surface of the base 5. An air pump 53 is fixedly installed at the bottom of the base 5. An airbag 6 is provided inside the base 5. The top of the airbag 6 is in contact with the bottom of the glass window 4. An air inlet pipe 61 and an exhaust pipe 62 are fixedly connected to the bottom of the airbag 6. A first pressure sensor 7 and a second pressure sensor 8 are fixedly installed on the top of the airbag 6. A guide rail 51 is fixedly connected to the bottom of the base 5. The top end of the fork arm assembly 3 is slidably connected to the inside of the guide rail 51. A limit groove 501 is opened on the inner wall of the base 5. One side of the connecting block 41 is movably installed inside the limit groove 501.

[0025] The effect achieved by the entire embodiment 1 is as follows: the bottom of the glass window 4 is installed inside the base 5, the airbag 6 is inflated and in a bulging state, which lifts the glass window 4 upward so that the position of the glass window 4 when it rises can contact the top of the frame 1. The first pressure sensor 7 and the second pressure sensor 8 are both located between the airbag 6 and the glass window 4. When the glass window 4 is rising, it will exert downward pressure due to the resistance of the object. By adjusting the pressure threshold of the first pressure sensor 7 and the second pressure sensor 8, the pressure exerted by the glass window 4 on the object when it rises can be controlled.

[0026] Example 2, as Figures 1-5As shown, the output end of the first pressure sensor 7 is electrically connected with the input end of the buzzer 52, the air outlet end of the air pump 53 is fixedly connected with the bottom of the air inlet pipe 61, the exhaust pipe 62 penetrates the inner bottom of the base 5, the surface of the exhaust pipe 62 is fixedly installed with the electromagnetic valve 63, and the output end of the second pressure sensor 8 is electrically connected with the input end of the electromagnetic valve 63.

[0027] The whole effect achieved by the embodiment 2 is that the first pressure sensor 7 and the second pressure sensor 8 respectively control the on-off of the buzzer 52 and the electromagnetic valve 63, when the pressure of the glass window 4 exceeds the pressure threshold of the first pressure sensor 7 and the second pressure sensor 8, the buzzer 52 and the electromagnetic valve 63 are controlled to operate, the buzzer 52 can remind when the glass window 4 is clamped by an object, at the same time, the electromagnetic valve 63 is opened to make the air bag 6 exhaust to be in a contracted state, and the air pump 53 inflates the air bag 6 to make it restore to a puffed state, the air bag 6 is contracted to lower the position of the glass window 4, thereby avoiding the glass window 4 from being continuously lifted to cause injury when the glass window 4 is blocked by an object.

[0028] The working principle of the embodiment is that the lifting principle of the glass window 4 is realized by the prior art, the basic principle of the lifting of the glass window 4 is that when the power is turned on, the window motor 2 works to rotate and transmit to the sector gear through the speed reduction structure, the sector gear drives the fork arm assembly 3 to rotate, the lower end of the auxiliary arm moves linearly along the fixed auxiliary guide rail, and the upper end moves linearly along the main guide rail in the opposite direction of the main arm, thereby realizing the lifting of the glass window 4, when there is an object on the path of the glass window 4 when the glass window 4 is lifted, the glass window 4 will be subjected to a relatively downward pressure, the glass window 4 transmits the pressure to the first pressure sensor 7 and the second pressure sensor 8, when the pressure of the glass window 4 exceeds the pressure threshold of the first pressure sensor 7 and the second pressure sensor 8, the buzzer 52 and the electromagnetic valve 63 are controlled to operate, the buzzer 52 can remind when the glass window 4 is clamped by an object, at the same time, the electromagnetic valve 63 is opened to make the air bag 6 exhaust to be in a contracted state, the air bag 6 is contracted to lower the position of the glass window 4, when the position of the glass window 4 is adjusted to the top, the glass window 4 leaves a certain safety distance from the top end of the vehicle frame 1, thereby achieving the auxiliary anti-pinch effect, and the distance between the glass window 4 and the top end of the vehicle frame 1 is not more than 3-5 cm, and the air bag 6 is inflated by closing the electromagnetic valve 63 and operating the air pump 53, so that the air bag 6 can be puffed again, thereby enabling the glass window 4 to be reset.

[0029] The above is only a preferred embodiment of the present application, and does not limit the present application in other forms, any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made on the basis of the technical essence of the present application to the above embodiments still belongs to the protection scope of the technical scheme of the present application.
