When folding, the driving mechanism 30 drives the sliding block 50 to return, and the first connecting rod 41 and the second connecting rod 42 of at least two folding mechanisms 40 of the folding mechanisms 40 can be folded to the minimum state, so that the folding is convenient, the automatic lifting operation is simple and convenient, and the sun-shading and heat-insulating effects are good.

Specifically, in the present embodiment, the driving mechanism 30 includes a motor 31, a transmission shaft 32, and a slide rail 33, a rotating shaft of the motor 31 is synchronously coupled with the transmission shaft 32, the slide rail 33 is mounted on the mounting base 10, and the slide rail 33 can be fixed on the mounting base 10 by a screw. The sliding block 50 is slidably mounted on the sliding rail 33, that is, the sliding block 50 can slide along the sliding rail 33 without deviation, the transmission shaft 32 is synchronously connected with the sliding block 50, and the transmission shaft 32 is used for driving the sliding block 50 to slide in the rotating process.

On the basis of the structure, when the sliding block 50 is driven to move, the motor 31 can drive the transmission shaft 32 to rotate, and the transmission shaft 32 can drive the sliding block 50 to slide along the sliding rail 33. In this embodiment, the slider 50 and the transmission shaft 32 can be guided by screw-thread fit, that is, by providing screw threads on the transmission shaft 32, the slider 50 and the transmission shaft 32 can be screw-driven by a nut, and the linear motion of the slider 50 can be guided by the rotation of the transmission shaft 32.

In addition, the sliding of the slider 50 can also be directly realized by a linear motion output mechanism (such as an air cylinder).

Further, the driving mechanism 30 further includes a gearbox 34, a rotating shaft of the motor 31 is synchronously coupled with an input end of the gearbox 34, and an output end of the gearbox 34 is synchronously coupled with the transmission shaft 32. Therefore, the rotation of the rotating shaft of the motor 31 can be transmitted, accelerated or decelerated through the gearbox 34, and the transmission structure is stable.

More specifically, the output end of the gearbox 34 is synchronously coupled with a first gear 35, the end of the transmission shaft 32 is synchronously coupled with a second gear 36, and the first gear 35 is meshed with the second gear 36, so that the rotation of the transmission shaft 32 can be further transmitted through the first gear 35 and the second gear 36, and the transmission structure is more stable.

Of course, the second gear 36 and the end of the transmission shaft 32 can be coupled synchronously by a universal joint 37, the universal joint 37 being commercially available, and the specific structure and working principle thereof being known directly to the person skilled in the art. Because the universal joint 37 can realize continuous rotation of the two connected shafts under the condition of an included angle between the axes, and reliably transmit torque and motion, namely, stable transmission can be driven when the included angle exists between the axis of the transmission shaft 32 and the axis of the second gear 36.

Further, in the present embodiment, the end of the second link 42 of the lowermost folding mechanism 40 may be hinged to the mounting base 10 by a hinge block 60, and an elastic member is connected between the hinge block 60 and the sliding block 50, and the elastic member is used for providing elastic stress for sliding the sliding block 50 away from the hinge block 60.

That is, when the sliding block 50 slides close to the hinge block 60 under the driving of the driving mechanism 30, the elastic member can be compressed, and a certain pressure is required for the compression of the elastic member, so that the sliding block 50 can be controlled to move slowly, the folding mechanism 40 can be lifted slowly, the curtain body 20 can be driven to be lifted slowly, and the windshield can be prevented from being scratched after the curtain body 20 is lifted quickly.

On the basis of the structure, when the sliding block 50 is driven by the driving mechanism 30 to slide close to the hinge block 60, the elastic component can be compressed, and the elastic component needs a certain pressure to be compressed, so that the sliding block 50 can be controlled to move slowly, the folding mechanism 40 can be raised slowly, the curtain body 20 can be driven to rise slowly, when the sliding block 50 moves close to the hinge point between the second connecting rod 42 and the mounting seat 10 to touch the first limit switch, the first limit switch can generate an electric signal, the driving mechanism 30 stops according to the electric signal, and the sliding block 50 moves to the limit position, and stops moving in time.

Conversely, during folding, the driving mechanism 30 drives the slider 50 away from the hinge block 60, and the spring is reset, and during the extension of the spring, the support portion slowly descends, thereby driving the curtain 20 to slowly descend. When the sliding block 50 moves away from the hinge point of the second connecting rod 42 and the mounting base 10 to touch the second limit switch, the second limit switch can generate an electric signal, the driving mechanism 30 stops according to the electric signal, and the sliding block 50 moves to the limit position and stops acting in time.

Preferably, the mounting seat 10 is provided with a mounting cavity, the driving mechanism 30 is mounted in the mounting cavity, and the curtain body 20 and the at least two folding mechanisms 40 are both used for being stored in the mounting cavity, so that after the curtain body 20 is folded under the driving of the at least two folding mechanisms 40, the curtain body can be stored in the mounting cavity, thereby facilitating folding and reducing the overall volume.
