[0054] The utility model provides a kind of rope wheel type glass lifter, including motor drive mechanism 50, traction rope 60 and traction rope cutting device, traction rope cutting device is fixedly connected with the shell 501 on motor drive mechanism 50, shell 1 is fixedly connected with shell 501, cutting channel 11 on traction rope cutting device is communicated with the access channel 5011 on shell 501, traction rope 60 passes through cutting channel 11 and access channel 5011 and traction rope 60 can be moved under the drive of motor drive mechanism 50.

[0055] The rope wheel type glass lifter includes a single guide rail rope wheel lifter and a double guide rail rope wheel lifter. The single guide rail rope wheel lifter includes a motor driving mechanism 50, a traction rope 60, a glass lifting guide rail 70, a glass mounting sliding block 80, an upper guide pulley 90, a lower guide pulley 100 and a traction rope cutting device. The upper end of the glass lifting guide rail 70 is provided with the upper guide pulley 90, and the lower end is provided with the lower guide pulley 100. The glass mounting sliding block 80 is in sliding connection with the glass lifting guide rail 70 to form a sliding assembly. The traction rope 60 is in a closed structure. The traction rope 60 is sleeved in a groove on the outer surface of a driving wheel shaft in the motor driving mechanism 50, and then sequentially passes through an access passage 5011 at the upper end, a cutting passage 11, the upper guide pulley 90, the glass lifting guide rail 70, the lower guide pulley 100, an access passage 5011 at the lower end, and finally returns to the groove on the outer surface of the driving wheel shaft. A part of the traction rope 60 is connected with the glass mounting sliding block 80.

[0056] When the motor in the motor driving mechanism 50 rotates, the power of the motor drives the driving wheel shaft to rotate through the worm and gear structure in the motor driving mechanism 50. The rotation of the driving wheel shaft drives the traction rope 60 to move. Since the traction rope 60 and the glass mounting sliding block 80 are fixedly connected, the movement of the traction rope 60 drives the glass mounting sliding block 80 to move up and down along the glass lifting guide rail 70, thereby realizing the glass lifting function. The double guide rail rope wheel lifter has one more sliding assembly than the single guide rail rope wheel lifter. The traction rope 60 is wound in an 8-shaped manner, so that the glass mounting sliding blocks 80 on the glass lifting guide rails 70 on both sides are synchronously lifted and lowered.

[0057] The motor driving mechanism 50 adopts a worm and gear structure for power transmission. The worm is installed on the motor shaft, and the driving wheel shaft for driving the traction rope 60 is connected with the worm. Due to the one-way rotation characteristic of the worm and gear structure, when the motor stops rotating, the worm is automatically locked by the mechanism, and the traction rope 60 cannot move, thereby realizing the locking of the vehicle window glass on the sliding guide rail. When an accident occurs, the traction rope 60 is cut off through the traction rope cutting device. In this way, the glass mounting sliding block 80 loses the fixation of the traction rope 60 in the case that the driving wheel shaft is still locked by the worm and gear mechanism, so that the vehicle window glass can move the glass mounting sliding block 80 through external force, thereby realizing the opening of the vehicle window glass.

[0058] The present application has small changes to the existing rope wheel type vehicle window glass lifter. Except that the shell 1 of the traction rope cutting device is added, the rest does not need to be changed. The application has low cost and is easy to popularize on a large scale. The working principle is simple. The traction rope 60 can be cut off, and no other redundant operations are needed.

[0059] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
