[0046] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described in combination with the embodiments of the present invention and the accompanying drawings. It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0047] Embodiment 1

[0048] See also Figures 1 to 3 An embodiment of the present invention provides an electric mechanical sunshade, including a bracket assembly 1, a sun visor 2, and a driving module; wherein the driving module includes a telescopic device 3, a swing arm 4 and a hinge 5; the rear ends of at least two parallel swing arms 4 are hinged to the bracket assembly 1, and the front ends of the swing arms 4 are hinged to the hinge 5 to form a parallelogram mechanism therewith; the middle part of the back side of the sun visor 2 is hinged to the front end of the swing arm 4 through the hinge 5; the movable end of the telescopic device 3 is hinged to the back end of the sun visor 2, and the mounting end of the telescopic device 3 is connected to the bracket assembly 1; and a limit portion 6 is fixedly provided on the bracket assembly 1, so that the swing arm 4 contacts the limit portion 6 for limit when it swings outward to the maximum amplitude.

[0049] The working principle of the present invention is:

[0050] When the telescopic device 3 contracts, it will first drive the swing arm 4 to swing outward. Since the hinge 5 and the swing rod form a parallelogram mechanism, the hinge 5 and the sun visor 2 connected thereto will not open or close until the swing arm 4 and the limiter 6 are in contact with each other. At this time, a gap is formed between the sun visor 2 and the bracket assembly 1, which can be used for ventilation. If the user only needs ventilation, the telescopic device 3 can stop contracting at this point.

[0051] If you want to further open the sun visor 2, you can control the telescopic device 3 to continue to shrink, and then start to drive the sun visor 2 to open by relying on the hinge 5. The opening range corresponds to the shrinkage range of the telescopic device 3, so this opening range can also be controlled at will.

[0052] If you want to close the sun visor 2, just extend the telescopic device 3 again. The closing movement is the reverse movement of the above-mentioned movement, which will not be described in detail here.

[0053] For the telescopic device 3, the present invention has three preferred embodiments.

[0054] In this embodiment, as a first preferred solution, the telescopic device 3 is an electric push rod, the movable end of the electric push rod is hinged to the back end of the sun visor 2, and the mounting end of the electric push rod is hinged to the bracket assembly 1.

[0055] This embodiment is the simplest solution. The electric push rod hinged to the bracket assembly 1 can swing automatically to adapt to the movement during the extension and retraction process. Generally, the electric push rod has its own drive motor. However, the electric push rod that swings with the extension and retraction is only suitable for the independent operation of a single sun visor 2, and it is difficult to achieve the linkage between multiple sun visors 2.

[0056] In order to make the driving module have a more certain action, preferably, a spring 7 with an elastic force directed outward is provided between the swing arm 4 and the bracket assembly 1. During the contraction of the telescopic device 3, the spring 7 will first provide assistance to push the swing rod to swing outward. This avoids the swing action being hindered due to the poor swinging of the swing rod, which affects the working rhythm of the entire driving module. At the same time, when an electric push rod is used as the telescopic device 3, it can provide a force in both the telescopic direction, so when the sun visor 2 is closed, it can also provide a thrust to make the swing rod overcome the elastic force of the spring 7 and swing closed.

[0057] Embodiment 2

[0058] The difference between this embodiment and the first embodiment is that a connecting rod 8 is added between the telescopic device 3 and the sun visor 2, thereby improving the overall running track of the mechanism.

[0059] See also Figures 4 to 7 Specifically, the telescopic device 3 is an electric push rod, and a connecting rod 8 is connected between the electric push rod and the back end of the sun visor 2. The two ends of the connecting rod 8 are respectively hinged to the back end of the sun visor 2 and the movable end of the telescopic device 3; the mounting end of the telescopic device 3 is fixedly installed on the bracket assembly 1.

[0060] In this embodiment, the telescopic device 3 is also an electric push rod, but it is no longer a swinging structure, but is fixedly installed on the bracket assembly 1. Since the telescopic device 3 as a whole no longer swings, it is conducive to realizing the linkage between multiple drive modules of multiple sun visors 2.

[0061] See also Figure 7 With the above advantages, as a preference, the sun visor 2 is provided with multiple pieces, each of which is transmission connected to the corresponding driving module; and the bracket assembly 1 is also provided with a main shaft 9 and a main motor, the main motor is transmission connected to the main shaft 9, and each telescopic device 3 is transmission connected to the main shaft 9.

[0062] The main motor drives the main shaft 9, and then drives all the drive modules, which is conducive to reducing the use of motors, reducing the size of the equipment, and saving equipment costs. The main shaft 9 and the telescopic device 3 are driven by a gear set or a similar transmission structure.

[0063] As a further preference, the transmission between the telescopic device 3 and the main shaft 9 is controlled by an electromagnetic clutch 10.

[0064] Furthermore, the bracket assembly 1 is in a grid shape, and a sun visor 2 and a corresponding driving module are provided at each grid; the electric push rod and the connecting rod 8 extend along the grid frame of the bracket assembly 1.

[0065] It should be noted that the specific shapes of the multiple sun visors 2 are not limited here. The shapes of the multiple sun visors 2 may not be exactly the same. The multiple sun visors 2 can cooperate with each other to form a closed shape to achieve closure. In this solution, the multiple sun visors 2 also divide the field of view into multiple plate structures.

[0066] The opening and closing principle of this embodiment is the same as that of the first embodiment, and the technical solution of providing a spring 7 between the swing arm 4 and the bracket assembly 1 to help determine the motion trajectory can also be inherited and will not be elaborated here.

[0067] It should be noted that, because in the first and second embodiments, the telescopic device 3 can provide force in both the extension and retraction directions, the driving module is not necessarily installed at the top of the sun visor 2, but can be installed upside down at the bottom of the sun visor 2. The two embodiments only have corresponding changes in action, and the principles are the same.

[0068] Embodiment 3

[0069] The difference between this embodiment and the first embodiment is that the telescopic device 3 adopts a structure in which the traction wire 12 pulls the sliding block 11 to telescopically slide.

[0070] See also Figures 8 to 11Specifically, the telescopic device 3 includes a slider 11, a traction wire 12 and a winding wheel 13; the slider 11 is slidably connected to the bracket assembly 1, serving as the movable end of the telescopic device 3; a connecting rod 8 is provided between the slider 11 and the sun visor 2, and the two ends of the connecting rod 8 are respectively hinged to the top of the back side of the sun visor 2 and the slider 11; the top end of the traction wire 12 is fixedly connected to the winding wheel 13 and wound on the surface of the winding wheel 13, and the bottom end of the traction wire 12 is fixedly connected to the slider 11, so that when the winding wheel 13 rotates, the winding traction wire 12 drives the slider 11 to slide.

[0071] This structure is completely different from the first and second embodiments, and the traction wire 12 can only generate a tensile force for contraction, but cannot generate a thrust for extension. Therefore, the technical solution of setting a spring 7 between the swing arm 4 and the bracket assembly 1 to ensure the motion trajectory cannot be adopted in this embodiment.

[0072] Preferably, the limit portion 6 is provided with an electromagnetic device 14, and the swing arm 4 is fixedly provided with an attraction portion that cooperates with the electromagnetic device 14. Thus, when the swing arm 4 reaches the limit position of the limit portion 6, the electromagnetic device 14 generates a magnetic force to attract the swing arm 4; when the sun visor 2 is closed, the electromagnetic device 14 will be demagnetized to release the swing arm 4.

[0073] Relatively speaking, the traction wire 12 is more conducive to freely extending and transmitting along the bracket assembly 1, so this embodiment is the most advantageous technical solution for the linkage of multiple sun visors 2 and multiple drive modules.

[0074] In this embodiment, preferably, the sun visor 2 is provided with a plurality of pieces, each piece is connected to the corresponding driving module by transmission; and the bracket assembly 1 is also provided with a main shaft 9 and a main motor, the main motor is connected to the main shaft 9 by transmission, and each winding wheel 13 is connected to the main shaft 9 by transmission. As a further preference, the transmission between the winding wheel 13 and the main shaft 9 is controlled by an electromagnetic clutch 10.

[0075] See Fig.11 Furthermore, the bracket assembly 1 is in a grid shape, and a sun visor 2 and a corresponding driving module are provided at each grid; the slider 11, the connecting rod 8 and the traction wire 12 extend along the grid frame of the bracket assembly 1, wherein a fixed pulley 15 is provided at the intersection of the frame, and the traction wire 12 is wound around the surface of the fixed pulley 15. Fig.11 The bracket assembly 1 shown in the figure is an open structure, the purpose of which is to show the direction of the traction wire 12 and the fixed pulley 15, the driving module and other components. The actual installation can be completely shielded and protected on the surface.

[0076] Different from the second embodiment, the traction wire 12 in this embodiment has a freer direction and the guide is changed by the fixed pulley 15. Therefore, the linkage is more convenient to realize with fewer restrictions, and the shape and division of the sun visor 2 are more free and varied.

[0077] The present invention provides an electric mechanical sunshade, which has the function of extending the sun visor 2 outward to leave a gap for ventilation, and can also further open the sun visor 2 to let light in, and the light transmission range can be adjusted according to the opening range of the sun visor 2. The drive module is small in size and simple in structure, which saves volume and can be easily hidden. In particular, the bracket assembly 1 can be constructed into a grid-like frame structure, and the drive module can be extended along the frame, which has little obstruction to the field of vision. Multiple sun visors 2 can be spliced ​​to form a closed structure, so that the field of vision is divided into multiple sun visors 2, and the opening and closing of specific positions in the field of vision can be realized by opening and closing the sun visors 2 separately. At the same time, it has a linkage scheme, and multiple sun visors 2 can be individually controlled by the electromagnetic clutch 10, and can be driven by a single motor to simplify the drive structure.

[0078] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
