[0025] When the above-mentioned device is used in practice, when the vehicle falls into the water, the water pressure will squeeze the first airbag 27, and the internal pressure of the first hydraulic chamber 26 will increase, driving the first hydraulic rod 28 to move forward, and the first hydraulic rod 28 will drive the slide plate 210 to slide on the inner wall of the slide rail 29, and the slide plate 210 will drive the joint 21 to move forward, and the joint 21 will drive the fixed rod and the limit block 25 to slide on the inner wall of the limit groove 24, and the spherical buckle 23 will be detached from the outer wall of the fixed rod through the slide groove 22, so that the joint 21 will be detached from the outer wall of the output end of the motor body 1, so that the motor body 1 can no longer drive the joint 21 to rotate, and the joint 21 no longer drives the glass to be lifted, thereby disconnecting from the motor body 1, so that the motor body 1 can no longer control the rotation of the joint 21, resulting in the motor body 1 no longer driving the glass to be lifted.

[0026] Embodiment 2 See also Figure 1-Figure 6On the basis of the first embodiment, the front of the motor body 1 is equipped with a closing device 3, which includes a second hydraulic chamber 31, which is fixedly connected to the side of the motor body 1, a connecting pipe 33 is fixedly connected to the side of the second hydraulic chamber 31, a disc hydraulic chamber 32 is fixedly connected to the side of the connecting pipe 33, a second hydraulic rod 34 is slidably connected to the piston at one end of the second hydraulic chamber 31, the second hydraulic rod 34 is fixedly connected to the side of the slide 210, a third hydraulic rod 35 is slidably connected to the piston at one end of the disc hydraulic chamber 32, and a fan-shaped sealing sheet 36 is slidably connected to the piston at one end of the third hydraulic rod 35. The function of the closing device 3 is to provide a sealed space inside the motor body 1 to prevent water from entering the motor body 1, thereby protecting the components of the motor body 1. The closing device 3 includes a second hydraulic chamber 31, which is connected to the disc hydraulic chamber 32 through a connecting pipe 33. The second hydraulic rod 34 and the third hydraulic rod 35 are slidably connected to the piston in the hydraulic chamber, and the position and running trajectory of the slide 210 are controlled by these hydraulic components.

The back of the fan-shaped sealing sheet 36 is fixedly connected with a connecting rod 38, and the bottom of the connecting rod 38 is fixedly connected with an extrusion plate 39. The back of the disc hydraulic chamber 32 is fixedly connected with a fixed block 37, which ensures a firm connection between the disc hydraulic chamber 32 and the motor body 1, preventing the hydraulic system from loosening or shifting during operation. The limiting ring 312 has a moving groove 310 opened on the inner wall. This design allows the fan-shaped sealing sheet 36 to slide therein, thereby ensuring that the pressure in the hydraulic system is evenly distributed.

The front of the motor body 1 is fixedly connected with the second airbag 311, and the second airbag 311 is assembled on the outer edge of the output end of the motor body 1.

[0027] When the above-mentioned equipment is used, the slide plate 210 moves toward the front, and the slide plate 210 drives the second hydraulic rod 34 to move toward the front. During the movement of the second hydraulic rod 34, the internal pressure of the second hydraulic chamber 31 increases, and the second hydraulic chamber 31 transmits the pressure to the inside of the disc hydraulic chamber 32 through the connecting pipe 33. The disc hydraulic chamber 32 drives the third hydraulic rod 35 to move toward the bottom, and the third hydraulic rod 35 drives the fan-shaped sealing plate 36 to move toward the bottom to seal the outer wall of the output end of the motor body 1. At the same time, the fan-shaped sealing plate 36 drives the connecting rod 38 to descend, and the connecting rod 38 drives the extrusion plate 39 to descend, and the extrusion plate 39 squeezes the second airbag 311, so that the second airbag 311 performs a secondary sealing on the outer wall of the output end of the motor body 1.

The moving device 4 includes a horizontal plate 41, which is rotatably connected to the front of the motor body 1 through a bearing, ensuring that the horizontal plate 41 can be accurately controlled when the motor body 1 is working. The rack 42 is connected to the side of the slide plate 210 and meshes with the circular gear 49 on the rotating rod 43, so that the glass can be lowered by the circular gear 49, preventing the glass from being unable to be opened due to water pressure, which affects the rescue. The limit rod 44 controls the position of the glass connecting block 46 to ensure that the glass does not move excessively or fall off during the lifting process, providing the necessary safety. The outer wall of the limit rod 44 is movably sleeved with a spring 45, and the two ends of the spring 45 are respectively fixedly connected to the bottom of the glass connecting block 46 and the top of the cross plate 41.

The two ends of the spring 45 are respectively fixedly connected to the bottom of the glass connecting block 46 and the top of the cross plate 41, ensuring the stability and rebound force during the lifting and lowering of the glass, and preventing the glass from being damaged by external force impact. The circular gear 49 meshes with the rack 42 . The circular gear 49 can achieve precise linear motion conversion by meshing with the rack 42 , and can change the linear motion of the slide plate 210 into rotational motion, thereby driving the glass to descend.

[0029] When the above-mentioned device is in specific use, when the glass lifting is in normal use, the spring 45 drives the rotating rod 410 and the second extrusion block 48 to rise, so that the second extrusion block 48 is always with the first extrusion block 47, and the bottom contact slide plate 210 drives the rack 42 to move forward, the rack 42 drives the circular gear 49 to rotate, the circular gear 49 drives the rotating rod 43 to rotate, the rotating rod 43 drives the rotating rod 410 and the block 411 to rotate, the rotating rod 411 drives the second extrusion block 48 to rotate, the second extrusion block 48 no longer limits the first extrusion block 47, the spring 45 drives the glass connecting block 46 to descend, and the glass connecting block 46 drives the vehicle glass to descend.
