Wherein, the inner wall of the driving block 5 is provided with an oil delivery cavity 50, the top end of the movable magnetic block 7 is fixedly provided with an adjusting block 9 positioned in the oil delivery cavity 50, the surface of the adjusting block 9 is fixedly provided with a driving spring 10, one end of the driving spring 10 is fixedly arranged with the inner wall of the driving block 5, the inner wall of the movable magnetic block 7 is provided with an oil delivery passage 70 communicated with the oil delivery cavity 50, one end of the driving block 5 is fixedly provided with a decompression tube 14, the middle part of the decompression tube 14 is fixedly provided with a communicating tube 13, the communicating tube 13 is fixedly arranged with the middle part of the mounting frame 4, the inner wall of the decompression tube 14 is provided with an oil storage cavity 140 communicated with the oil delivery passage 70, the other end of the driving block 5 is fixedly provided with a stabilizing rod 11, one end of the stabilizing rod 11 is fixedly arranged with the mounting frame 4, the inner wall of the stabilizing rod 11 is provided with a stabilizing cavity 110, the inner wall of the driving block 5 is provided with a damping channel 51 communicated with the oil conveying cavity 50, and the stable cavity 110 is communicated with the oil conveying cavity 50 through the damping channel 51, so as to prevent violent window opening, stable lifting and clamping injury, therefore, the two sides of the movable magnetic block 7 are respectively connected with the decompression pipe 14 and the stable rod 11, medium oil is filled in the stable cavity 110 in the stable rod 11 and the oil storage cavity 140 in the decompression pipe 14, so that in the working process, the medium oil flows from the damping channel 51 through the medium oil, further the speed reduction is realized, the moving speed is kept stable, meanwhile, in the lifting and closing process of the glass 2, as the upper part of the glass 2 is pushed to the top of the vehicle door or clamped, the adjusting block 9 can compress the driving spring 10 again, and the medium flow in the damping channel 51 and the oil conveying cavity 50 is blocked through the adjusting block 9, so that when the driving block 5 needs to move, the medium oil in the oil storage cavity 140 or the stabilizing cavity 110 is inevitably extruded, and the medium oil cannot be compressed, so that the glass 2 cannot move again when the glass 2 clamps a person and rises to the top, the phenomenon that the glass 2 is opened due to the violent dragging of the glass is avoided, and secondary damage caused by the secondary force after the person is clamped is avoided.

Meanwhile, the locking action can be realized by contacting the top of the glass 2 with the top, so that the lifter can be suitable for vehicles with different lifting heights, and the phenomenon that the lifter needs to be redesigned due to different vehicle types is avoided.

Moreover, because the magnetic attraction between the movable magnetic blocks 7 can be autonomously contracted, when the electric coil 8 is powered off, the driving block 5 can automatically lock the glass 2 through the attraction in the bracket of the movable magnetic block 7, so that the glass 2 can be autonomously closed when the vehicle is not used, and when the vehicle is started again, the current passing through the electric coil 8 is still adjusted last time, so that the driving block 5 can be moved towards two sides through the magnetic force generated by the electric coil 8, the glass 2 is automatically opened, and finally the purposes of automatically locking the window and memorizing the height of the window are achieved.

Wherein, the side wall movable mounting of moving magnetic block 7 has sealing ring 15, and sealing ring 15 and the inner wall fixed mounting of drive block 5, in order to prevent moving in-process of moving magnetic block 7 and drive block 5, from the phenomenon that the medium oil leaks taking place in the activity, therefore through the inner wall fixed mounting of drive block 5 having sealing ring 15, because the material of sealing ring 15 is the rubber body, and then can realize the sealed of oil input chamber 50 through its sealing ring 15, thereby prevent the phenomenon of leaking.

Wherein, damping way 51 is elongated hole, in order to realize glass 2's steady lift, therefore through saying damping way 51 to be elongated hole, therefore make the medium by the in-process that passes through, have certain deceleration effect to make glass 2 more steady at the in-process that goes up and down, simultaneously, prevented to lead to the phenomenon of the quick laminating of drive block 5 because the magnetic attraction increase of moving magnetic block 7 department.

Wherein, decompress pipe 14 and firm pole 11 and be the telescopic link of inner chamber seal, in order to realize its glass 2 locking and prevent the phenomenon of pressing from both sides the people, therefore establish to the telescopic link through its decompression pipe 14 and firm pole 11, therefore the left and right back and forth movement through its adaptable its drive block 5 of telescopic link, and simultaneously, be equipped with sealed cavity through its decompression pipe 14 and firm pole 11 in, therefore pour into the medium oil of sufficient through the inner chamber, guaranteed opening and shutting of its drive block 5 and can only control through the magnetic force size of electric coil 8, when external pressure opens by force, through the medium seal in its deposit oil chamber 140 and firm chamber 110, and then realize the purpose of self-adaptation locking.

Wherein, the magnetic force range of the attraction between the movable magnetic blocks 7 is twice of the total length value of the mounting frame 4, the elastic force value of the driving spring 10 is less than the magnetic force value when the movable magnetic blocks 7 are attracted, the elastic force value of the driving spring 10 is one point three times of the total gravity value of the lifting scissors 3, the lifting frame 1 and the glass 2, in order to prevent the driving block 5 from being placed at the two ends of the mounting frame 4, the driving block 5 can not be pulled back in a self-adaptive manner, therefore, the magnetic attraction range between the movable magnetic blocks 7 is more than the length value of the mounting frame 4, when the movable magnetic blocks 7 are all opened, the glass 2 still has the capacity of jacking up, the normal lifting of the glass 2 is ensured, meanwhile, in order to ensure that the adjusting block 9 can seal the damping channel 51, therefore, the elastic force value of the driving spring 10 is less than the magnetic force value of the movable magnetic blocks 7, and after the glass 2 is loaded in the lifting process, the compression of the driving spring 10 will be precedent, so that the movement of the adjusting block 9 blocks the damping channel 51, and the locking and the non-movement of the adjusting block are realized through the medium in the oil delivery cavity 50 and the damping channel 51 is not communicated any more, so that the glass 2 is ensured to automatically stop lifting after being lifted to the top, meanwhile, the phenomenon that the clamping force is continuously increased is also ensured in the process of clamping people, in order to prevent the lifting frame 1, the glass 2 and the lifting scissors 3 from compressing the driving spring 10 due to the gravity, the elastic force value of the driving spring 10 is larger than the sum of all gravity values, the driving spring 10 is not ensured to have a certain compression space, and meanwhile, after the driving spring 10 is compressed, the driving block 5 can directly lock the oil delivery cavity 50 and the damping channel 51 through the adjusting block 9 due to the over-compression of the driving spring 10, so that the glass 2 cannot be lifted, an always locked phenomenon occurs.

The using method of the invention has the following working principle: firstly, fixing the mounting frame 4 to a vehicle door through mounting holes on two sides of the mounting frame 4, secondly, fixing the glass 2 to the lifting frame 1, and then continuously injecting oil into the stable cavity 110 through the oil inlet pipe 12 until the oil inlet pipe 12 is filled and sealed;

descending state (shown in fig. 4): the vehicle is ignited and started, the current passing through the electric coil 8 is enhanced through the control circuit, the magnetic force on two sides of the electric coil 8 is further increased, meanwhile, the magnetic poles on two sides of the electric coil 8 are respectively repelled with the magnetic poles of the movable magnetic blocks 7 on the driving blocks 5, the magnetic force generated by the electric coil 8 is further reduced, the magnetic attraction force of the movable magnetic blocks 7 on the two driving blocks 5 is weakened, the lifting scissors 3 are opened under the action of the gravity of the lifting frame 1 and the glass 2, the lifting scissors 3 slide on the mounting frame 4 through the positioning wheels 6 on the driving blocks 5, the trend that the driving blocks 5 respectively move towards two sides is realized, meanwhile, in the process that the two driving blocks 5 respectively move towards two sides, the driving blocks 5 compress the adjusting blocks 9 towards one side through the driving springs 10, and then the adjusting blocks 9 move towards the stabilizing rods 11 through the driving blocks 5, the stabilizing rod 11 is retracted, the decompression tube 14 extends, the medium in the stabilizing cavity 110 slowly flows into the oil delivery cavity 50 from the damping channel 51, meanwhile, the speed of the medium is reduced through the damping channel 51, then the medium oil flowing into the oil delivery cavity 50 flows back into the oil storage cavity 140 from the oil delivery channel 70, then the medium oil moves towards two sides through the driving block 5, the glass 2 descends, meanwhile, the current of the electric coil 8 is controlled, the field intensity generated by the electric coil 8 is changed, and the purpose of adjusting the glass 2 to different positions is achieved by overcoming the repulsive force of the electric coil 8 through the magnetic attraction between the movable magnetic blocks 7.

Raised state (shown in fig. 5): the current of the electric coil 8 is reduced through a vehicle flameout or manually through a control circuit, so that the electric coil 8 is enabled not to generate magnetism, then, magnetic attraction force is generated through the movable magnet blocks 7 on the two driving blocks 5, so that the two driving blocks 5 tend to move towards the middle, in the process that the driving blocks 5 move towards the middle, the positioning wheel 6 slides on the mounting frame 4, meanwhile, the lifting scissors 3 are closed, the glass 2 is pushed out, in the process that the driving blocks 5 approach the electric coil 8, the movable magnet blocks 7 drive the adjusting blocks 9 to compress the driving springs 10 through the attraction force of the movable magnet blocks 7, in the process that the driving blocks 5 move towards the electric coil 8 through the driving springs 10, at the moment, the decompression pipe 14 begins to contract, the stabilizing rods 11 begin to stretch, and the medium oil in the oil storage cavity 140 returns to the oil transmission cavity 50 through the oil transmission channel 70, then, the medium oil in the oil transportation cavity 50 slowly flows through the damping channel 51 and enters the stable cavity 110, so that the driving block 5 moves towards the middle part, and the glass 2 is ensured to be closed;

locked state after closing (shown in fig. 6): after the glass 2 of the vehicle body is pushed to the top, the glass 2 of the vehicle body is contacted with the top of a vehicle door, so that the lifting frame 1 cannot move upwards through the glass 2, and further cannot be closed through the lifting scissors 3, so that the driving block 5 cannot move in the direction of the electric coil 8, and then, because the magnetic attraction force is still kept between the movable magnetic blocks 7, the movable magnetic blocks 7 drive the adjusting block 9 to continue to move to the electric coil 8 through continuous adsorption of the movable magnetic blocks 7, so as to compress the driving spring 10, and the side walls of the adjusting block 9 block the connection between the damping channel 51 and the oil transmission cavity 50, so that the medium oil in the oil transmission cavity 50 cannot be transmitted to the stable cavity 110, and then, after the movable magnetic blocks 7 contract to the electric coil 8, because the medium in the oil storage cavity 140 cannot be compressed, so that the driving block 5 is fixed through the adsorption of the movable magnetic blocks 7, and further realize the locking phenomenon of the glass, similarly, when the glass 2 is lifted, people or objects are clamped, and the like, the driving spring 10 is compressed by the adjusting block 9 due to the increase of force, so that the adjusting block 9 blocks the damping channel 51, and a passage between the oil delivery cavity 50 and the stabilizing cavity 110 is blocked, so that the glass 2 cannot be lifted, and the phenomenon that people or objects are clamped and injured is ensured;

the parking lot memorizes a self-lifting state: because the electric coil 8 is automatically powered off in the closing process of the vehicle, the movable magnetic block 7 is automatically attracted to realize the automatic window locking function, but in the next use process, because the current value passed by the electric coil 8 is still the current regulated in the previous time, when the vehicle is used again, the electric coil 8 can generate the same magnetism again, the glass 2 is controlled at the last use position, and the vehicle window height memory function is achieved.
