Preferably, the lifting guide rod 120 is arranged in parallel with the screw rod 130, the lifting guide rod 120 can guide the lifting block 200 to move up and down and limit the lifting block 200 to rotate along with the screw rod 130, the driving element 110 can drive the screw rod 130 to rotate, and the screw rod 130 can drive the lifting block 200 to move up and down along the axial direction of the screw rod 130 through the threaded hole 210 when rotating.

Optionally, the number of the lifting guide rods 120 is two, and the two lifting guide rods 120 are respectively located at two sides of the screw rod 130, so that the stability of the lifting block 200 during movement can be ensured.

The actuator 300 is a component for directly driving an object to ascend and descend, the actuator 300 is connected to the ascending and descending block 200, so that the actuator 300 can ascend and descend together when the ascending and descending block 200 ascends and descends, and the driving component 110 can drive the ascending and descending block 200 to ascend and descend through the screw rod 130 so as to drive the actuator 300 to ascend and descend.

Compared with the traditional driving structure, the lifting driving device can be arranged below a vehicle window, and the actuating element 300 is driven by the lifting block 200 to push the curtain cloth of the sun-shading curtain or the vehicle window glass to lift, and the cable structure is not used for driving, so that the structure is very compact and is very hidden.

The lifting driving device is arranged at the position of a door of an automobile, particularly can be arranged below a window, so that the lifting driving device is suitable for driving the window glass to lift or driving the curtain cloth of the sun-shading curtain to lift.

As shown in fig. 1, 3, 4, and 5, optionally, the actuating element 300 includes a connecting rod 310 and a traction strip 320 adapted to the top end of the shade fabric of the sunshade curtain, one end of the connecting rod 310 is fixedly connected to the lifting block 200, the traction strip 320 is connected to the other end of the connecting rod 310, and the connecting rod 310 is used for supporting the traction strip 320, so that when the lifting block 200 moves, the traction strip 320 can be driven to lift by the connecting rod 310, and the shade fabric of the sunshade curtain is driven to lift.

As shown in fig. 2, the actuator 300 is optionally provided as a base plate adapted to the bottom of the window glass, the base plate being fixed to the lifter 200 and capable of being supported below the window glass so as to push the window glass up.

As shown in fig. 1 and 2, the driving element 110 includes a motor 111 and a speed reducer 112, the motor 111 and the speed reducer 112 are both fixedly connected to the mounting bracket 100, the motor 111 is linked to the speed reducer 112, and the screw 130 is linked to the speed reducer 112.

Alternatively, the screw 130 can be directly driven by the motor 111 to rotate, but in order to make the lifting process stable and controllable, the reducer 112 is specially added, and the motor 111 and the reducer 112 can be combined to smoothly and powerfully push the lifting block 200 and the actuator 300 to lift.

As shown in fig. 1-5, in the operation process of the lifting driving device, when an object (a window glass or a curtain cloth of a sun blind) needs to be driven to ascend, the motor 111 drives the screw rod 130 to rotate through the reducer 112, the screw rod 130 drives the lifting block 200 to ascend along the lifting guide rod 120 when rotating, and the object is jacked up through the actuator 300 when the lifting block 200 ascends, so that the object ascends; when the object is required to be driven to descend, the motor 111 rotates reversely, and the screw 130 drives the lifting block 200 to descend along the lifting guide rod 120, so as to pull the object to descend.

As shown in fig. 1 and 3 to 11, a capping mechanism installed in the lifting driving device includes: the cover holder 400 and the bracket assembly 500, wherein the cover holder 400 can be set to be a structure of a bottom of a vehicle window, the cover holder 400 is set above a lifting driving device, the cover holder 400 is provided with an opening groove 410 and a cover body 420, the cover body 420 covers the opening groove 410, and the actuating element 300 is located below the opening groove 410.

Since the sunshade needs to be raised from the lower side of the cover seat 400 (i.e. the lower side of the window position), the opening slot 410 needs to be reserved so that the sunshade can pass through, the cover body 420 can cover the opening slot 410 or be moved away from the opening slot 410, when the window glass or the sunshade falls down, the opening slot 410 needs to be covered by the cover body 420 so as to prevent sundries from entering the lower inner part of the window, and before the sunshade rises, the cover body 420 needs to be actively opened so that the sunshade can pass through the opening slot 410.

The bracket assembly 500 comprises a linkage bracket 510 and at least one linkage 520, the lifting block 200 and the linkage bracket 510 are arranged in an up-and-down corresponding manner, and the linkage bracket 510 is in linkage connection with the lifting block 200; one end of the linkage member 520 is connected to the linkage bracket 510, and the other end is connected to the cover 420, so that the linkage bracket 510 can drive the linkage member 520 to open or close the cover 420.

When the lifting block 200 is lowered, the linkage bracket 510 may be pushed to move so as to pull the cover body 420 to be covered in the opening groove 410 through the linkage 520, and it is supplementary to that, when the lifting block 200 is raised, the linkage bracket 510 may be raised by an external force so as to eject, push or remove the cover body 420 through the linkage 520.

Optionally, an elastic washer is disposed on the lifting block 200 and/or the linking bracket 510 to ensure that the linking bracket 510 is driven to descend to a position low enough to allow the linking member 520 to drive the cover 420 to press the opening groove 410.

Through the structure, the capping mechanism can be linked with the lifting driving device, so that the capping mechanism is automatically opened before the object is driven to lift, and the capping mechanism is automatically closed after the object is lowered.

As shown in fig. 1, 3, 4, 5, 6, and 7, in one embodiment, the capping mechanism is configured to move to an open configuration, the cover body 420 is separated from the cover seat 400, and the cover body 420 is pressed against the position of the open slot 410 by the link 520, or the cover body 420 is moved away from the position of the open slot 410 by the link 520.

The capping mechanism further includes a fixing seat 600, the fixing seat 600 is fixedly disposed, the fixing seat 600 is provided with a chute 610, the link 520 is provided with a guide pin 530, the guide pin 530 is inserted into the chute 610 and can guide the link 520 to move along the chute 610, so that the link 520 pushes the cover body 420 to move to one side of the opening groove 410 after being opened.

On the basis of the above embodiment, the elastic member 620 is used to drive the bracket assembly 500 to automatically lift and remove the cover 420 when the lifting block 200 is lifted, wherein the fixing seat 600 is provided with the elastic member 620, the elastic member 620 is connected with the link 520, and when the lifting block 200 is lifted and separated from the link bracket 510, the elastic member 620 pulls the link 520 to move along the inclined slot 610, thereby opening the cover 420.

In this embodiment, before the lifting driving device is not lifted, the lifting block 200 can press the linkage bracket 510 to limit the lifting of the linkage member 520, so as to ensure that the cover body 420 covers the opening groove 410, when the lifting block 200 is lifted, the elastic member 620 pulls the linkage member 520 to move along the inclined groove 610, and the linkage member 520 drives the cover body 420 to move obliquely upward, that is, the cover body 420 is separated from the opening groove 410 and then moves to one side of the opening groove 410, so that the opened cover body 420 exposes the opening groove 410, and the opened cover body 420 is prevented from blocking the lifting of an object.

It should be added that, in the actual structure, the linking bracket 510 is provided with a hole which is slightly larger than the diameter of the lifting guide rod 120, and the lifting guide rod 120 passes through the hole, so that the linking bracket 510 and the linking member 520 can move vertically and horizontally in a small amplitude, thereby ensuring that the whole bracket assembly 500 can move obliquely.
