The curtain body 20 may be connected to an end of the first link 41 and an end of the second link 42 of the uppermost folding mechanism 40.

On the basis of the above structure, when using the dual-lifting type electric automobile sunshade of the present invention, and using the dual-lifting type electric automobile sunshade for the windshield of an automobile as an example, the mounting base 10 can be installed in front of the instrument panel of an automobile, when shading, the driving mechanism 30 is started, the driving mechanism 30 can drive the slider 50 to move toward the hinge point close to the second connecting rod 42 and the mounting base 10, and further drive the first connecting rod 41 and the second connecting rod 42 located at the bottom to be relatively close to each other, because the middle portions of the first connecting rod 41 and the second connecting rod 42 are hinged in a crossed manner, the top ends of the first connecting rod 41 and the second connecting rod 42 can be far away from each other, and further drive the bottom ends of the first connecting rod 41 and the second connecting rod 42 adjacent to each other to be far away from each other, and the top ends of the first connecting rod 41 and the second connecting rod 42 to be close to each other, and further drive the first connecting rod 41 and the, thereby, the first link 41 and the second link 42 located at the uppermost position are lifted, and the curtain body 20 can be unfolded for shading the sun.

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 mechanism 40 can be folded to the minimum state, so as to facilitate the folding.

Specifically, the two curtain bodies 20 can be respectively arranged at the connecting ends of the two groups of lifting components, so that the two curtain bodies 20 can be unfolded for shading the sun; the connecting ends of the two groups of lifting components can also be provided with a curtain body 20 with a larger area, and the two groups of lifting components can be lifted simultaneously to unfold or fold the sunshade curtain with a larger area; the automatic lifting operation is simple and convenient, and the sun-shading and heat-insulating effects are good.

Specifically, in this embodiment, the driving mechanism 30 includes a motor 31, two transmission shafts 32, and two sliding rails 33, the two sliding rails 33 are installed on the installation base 10 and respectively distributed on two sides of the motor 31, and the sliding rails 33 can be fixed on the installation base 10 by screws. The sliding blocks 50 of the folding mechanism 40 with the two sets of lifting assemblies located at the lowermost position are respectively and correspondingly slidably mounted on the two sliding rails 33, that is, the sliding blocks 50 can slide along the sliding rails 33 without deviation, one end of each transmission shaft 32 can be synchronously connected with the rotating shaft of the motor 31, the other end of each transmission shaft 32 is synchronously connected with the sliding blocks 50, and the transmission shafts 32 are used for driving the sliding blocks 50 to slide in the rotating process.

On this structure basis, when drive slider 50 moved, two transmission shafts 32 that can drive simultaneously were rotated in the pivot of accessible motor 31, and two transmission shafts 32 rotate alright drive two sliders 50 and slide along slide rail 33 to realize that two sets of lifting unit go up and down simultaneously, the synchronism is better. 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, the gearbox 34 is provided with two output ends, and the two transmission shafts 32 can be respectively and synchronously coupled with the two transmission shafts 32. Therefore, the rotation of the rotating shaft of the motor 31 can be transmitted through the gearbox 34, and is simultaneously output through two output ends of the gearbox 34 to accelerate or decelerate, and the transmission structure is stable. Of course, the gearbox 34 described above may alternatively be a prior art gear gearbox 34.

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.

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.

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.
