[0002] The automobile glass electric lifting system is mainly composed of a glass lifter, a glass and a glass guide rail. The glass lifter is driven by a motor to drive the glass to move up and down along the slide rail, so as to achieve the purpose of glass lifting. The glass lifter, also known as a window regulator or a lifter, includes a motor and a gear box. The motor drives the gear box to rotate, and the gear box pulls the steel wire rope to drive the automobile glass to move up or down along the glass guide rail in a certain way, and the glass can be stopped at any position.

[0003] Therefore, there are ordinary glass lifters without anti-pinch function and anti-pinch glass lifters on the market. In order to make the electric glass lifter not only maintain strong power, but also prevent the unsafe factor of being accidentally pinched during use, the current electric glass lifter has a certain intelligence. When the glass encounters a certain resistance during the lifting process, it will immediately stop lifting and descending to prevent the small probability of passengers being pinched. This is an electric anti-pinch glass lifter. Now the intelligent glass lifter system uses a Hall sensor and an ECU anti-pinch glass lifter. It is used in medium and high-end vehicles. Due to the use of PCB circuit board, the price of the intelligent glass anti-pinch lifter is relatively high, and the delivery cycle is relatively long, which affects the production of the glass lifter. The fault of the PCB board leads to the failure of the anti-pinch function, which also increases the risk of customer complaints. The ordinary glass lifter cannot prevent the risk of personnel injury, and the intelligent glass lifter is relatively expensive. SUMMARY

[0004] The present application aims to overcome the above technical deficiencies and provide an automobile anti-pinch window regulator device to solve the technical problems of high price and high failure rate of automobile anti-pinch window regulator in the technical field of automobile parts manufacturing.

[0005] To achieve the above technical purpose, the technical scheme of the present application provides an automobile anti-pinch window regulator device, which comprises:

[0006] The window regulator body comprises a driving source and a gear box. The output end of the driving source is drivingly connected to the input end of the gear box. The gear box has a gear end cover.

[0008] Compared with the prior art, the beneficial effects of the present application include:

[0009] 1. Compared with the ordinary glass lifter currently produced in China, the risk of passenger injury caused by the ordinary glass lifter is solved. During the use of the ordinary glass lifter, if the glass is pressed by foreign matter, the motor cannot identify the foreign matter, the glass will continue to rise, the glass lifting mechanism system will be damaged, and the passenger will be injured.

[0010] 2. At present, intelligent glass lifting systems are used in medium and high-end vehicles. The lifting system uses a Hall sensor and an ECU anti-pinch glass lifter.

[0023] In the through hole 222a, the sliding bearing is fixedly connected close to the inner wall of the through hole 222a, the pull rod 212 penetrates the sliding bearing, so that the gear body 211 is more smooth in the process of moving, the support body 214 is located at the lower end of the gear body 211, the support body 214 is arc-shaped, the support body 213 has two first mounting holes 214a penetrating from top to bottom, the support body 214 is screw-fixedly connected with the end face of the gear end cover 12a through the first mounting hole 214a, the placement block 222 has two second mounting holes 222b penetrating from top to bottom, and the placement block 222 is screw-fixedly connected with the end face of the gear end cover 12a through the second mounting hole 222b.

[0024] The electromagnetic valve unit 221 is fixedly connected with the gear end cover 12a and is adjacent to the electromagnetic element 223. When the anti-pinch system 2 is not working, the electromagnetic valve unit 221 is always powered to make the end face of the electromagnetic valve unit 221 always generate magnetism and be attracted to the electromagnetic element 223, thereby driving the pull rod 212 and the gear body 211 to move to the direction of the electromagnetic valve unit 221, so that the window crank body 1 normally lifts the glass. The torsion sensing unit 224 is fixedly connected with the end face of the gear end cover 12a. The torsion sensing unit 224 is connected with the control unit 23 through a plurality of wire harnesses to realize real-time feedback of data. The electromagnetic valve unit 221 is connected with the control unit 23 through a plurality of wire harnesses. Specifically, when the torsion sensing unit 224 monitors abnormal torsion, information is transmitted to the control unit 23. The control unit 23 analyzes and processes the information and transmits the execution result to the electromagnetic valve unit 221. After receiving the information, the electromagnetic valve unit 221 loses power and disconnects the electromagnetic element 223. Under the action of the elastic element 223, the gear body 211 locks the output end of the gear box 12 to prevent the output end of the gear box 12 from continuing to rotate and causing personal injury. In this embodiment, the control unit 23 has a delay function. After the person touches the glass, the person will immediately withdraw the finger due to the stress reaction. Then, the delay function of the control unit 23 plays a role, such as a delay of 10 s. The delay can be set. After the person is safe, the control unit 23 transmits information to the electromagnetic valve unit 221. After receiving the information, the electromagnetic valve unit 221 is powered. The electromagnetic valve unit 221 attracts the electromagnetic element 223. The gear body 211 and the output end of the gear box 12 are separated.

In the second embodiment, the bottom plate and the rotating reset spring are added to offset the impact force generated under the action of the movable bottom plate, and the rotating reset spring is used to reset the anti-pinch system 2, so that the service life of the anti-pinch system 2 can be greatly improved.

[0026] Working principle: the window winder body 1 drives the output end of the gear box 12 to rotate through the driving source 11, and outputs a torsional force through the output end of the gear box 12. Under normal circumstances, the driving source 11 will start at a normal speed, and the torsional force output value will also be normally output in a curve. If foreign matter or personnel touch the window, at this time the window winder body 1 is in a jammed state pulled by the steel wire rope, then the rotating speed of the driving source 11 is reduced, and the output torsional force of the output end of the gear box 12 is continuously increased. If no intervention is made, it will cause injury to the personnel. The torsional force sensing unit 224 installed in the device monitors the abnormal torsional force, transmits the information to the control unit 23, and the control unit 23 analyzes and processes the information, and transmits the execution result to the electromagnetic valve unit 221. After receiving the information, the electromagnetic valve unit 221 loses power and the electromagnetic element 223 is disconnected. Under the action of the spring element 223, the gear body 211 locks the output end of the gear box 12 to prevent the output end of the gear box 12 from continuing to rotate and causing injury to the personnel.

[0027] The control unit 23 has a delay function. After the personnel touch the glass, the fingers will be immediately withdrawn due to the stress reaction, and then the delay function of the control unit 23 plays a role, such as a delay of 10s, which can be set. After the personnel are safe, the control unit 23 transmits the information to the electromagnetic valve unit 221. After receiving the information, the electromagnetic valve unit 221 is powered on, the electromagnetic element 223 is attracted by the electromagnetic valve unit 221, the gear body 211 and the output end of the gear box 12 are separated, and the gear box 12 normally operates to drive the glass to normally move up and down through the steel wire rope.
