The vehicle 1000 includes a vehicle body 100 and a glass assembly 200. The glass assembly 200 is mounted on the vehicle body 100.

[0047] The glass assembly 200 includes a glass body 210 and a sunshade assembly 220. The sunshade assembly 220 is connected to the glass body 210. The sunshade assembly 220 is located on the side of the glass body 210 facing the interior of the vehicle 1000. Thus, on the one hand, the sunshade assembly 220 can block most of the ambient light from outside the vehicle 1000, thereby reducing the interior temperature, reducing the air conditioning load, and preventing external views while maintaining visibility inside the vehicle; on the other hand, the sunshade assembly 220 can be retracted to one side of the window, reducing the occupation of the interior headroom, improving the transparency of the interior view, and allowing the user to position the sunshade assembly 220 in any position, improving the accuracy of blocking glare from specific angles, and enhancing the user experience, sense of luxury, and aesthetics, thereby improving the experience for drivers and passengers.

[0048] For example, in this embodiment, the vehicle body 100 has an opening 1001, and the glass body 210 is installed at the opening 1001 and serves as a window. The sunshade assembly 220 is located on the side of the glass body 210 facing the interior of the vehicle 1000, thereby blocking the environment inside and outside the vehicle, improving privacy inside the vehicle, and enhancing the user experience for passengers. Of course, in some embodiments, the sunshade assembly 220 can also be applied to building ventilation windows, observation windows of processing equipment, etc., and this application embodiment does not specifically limit the application.

[0049] The glass assembly 200 may include, but is not limited to, a sunroof glass assembly, front and rear window glass assemblies, and side window glass assemblies. In this embodiment, the glass assembly 200 is described using a side window glass assembly as an example. Specifically, the glass body 210 of the glass assembly 200 has a light-transmitting area 2101. The light-transmitting area 2101 includes a first area 2102 and a second area 2103. The first area 2102 and the second area 2103 are joined together along the length of the vehicle 1000. The first area 2102 is generally rectangular in shape, and the second area 2103 is generally fan-shaped. The area formed by joining the first area 2102 and the second area 2103 is irregularly shaped. The sunshade assembly 220 is used to block the first area 2102 and the second area 2103. Of course, in some embodiments, the glass assembly 200 may also be configured as a front and rear windshield glass assembly, a ventilation window glass assembly, or other glass assemblies; this application embodiment does not specifically limit this. The shape of the first region 2102 can also be, but is not limited to, a square, etc., and the shape of the second region 2103 can also be, but is not limited to, a semicircle or a triangle, etc.

[0050] It should be noted that "irregular shape" refers to the shape of an object or area that is not regular. For example, an image formed by piecing together a rectangle and a fan is an irregular shape, i.e., an irregular pattern.

[0051] Vehicle 1000 may include, but is not limited to, cars, sports cars, trains, and other driving devices; this application embodiment does not impose such limitations. It is understood that, to enable those skilled in the art to better understand the sunshade assembly 220, the sunshade assembly 220 is described in detail using an application to a car as an example. It should be noted that the application of the sunshade assembly 220 to a car is for illustrative purposes only, and this application embodiment does not impose specific limitations. For example, the product application of the sunshade assembly 220 can be configured according to actual needs.

[0052] It should be noted that, Figure 1 The purpose is merely to illustrate the arrangement between the vehicle body 100 and the glass assembly 200, and is not to make specific limitations on the connection positions, connection relationships and specific structures of the various components. Figure 1 The structure of the vehicle 1000 illustrated in this embodiment is merely a schematic diagram and does not constitute a specific limitation on the vehicle 1000. In other embodiments of this application, the vehicle 1000 may include... Figure 1 The vehicle 1000 may also include, but is not limited to, wheels, seats, or power units, etc., as shown in the diagram.

[0053] Please refer to the following: Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the structure of the sunshade assembly 220 provided in the embodiments of this application; Figure 3yes Figure 2 A schematic diagram of the first part of the sunshade assembly 220 is shown. The sunshade assembly 220 includes a main sunshade 10, a secondary sunshade 20, and a drive mechanism 60. The secondary sunshade 20 and the main sunshade 10 are arranged along a first direction X. The first direction X intersects with the height direction Z of the main sunshade 10. The secondary sunshade 20 is configured with an irregular folding structure. The secondary sunshade 20 has a hinge end and a movable end disposed opposite to the hinge end. The hinge end is located at the top or bottom of the main sunshade 10 in the height direction Z, and at the end of the main sunshade 10 near the secondary sunshade 20 in the first direction X. The unfolded edge 201 of the secondary sunshade 20 away from the main sunshade 10 swings about the hinge axis of the hinge end toward a side closer to or away from the main sunshade 10. The drive mechanism 60 is used to drive the main sunshade 10 and the secondary sunshade 20 to sequentially close or unfold continuously along a preset trajectory S.

[0054] The sunshade assembly 220 provided in this application embodiment, on the one hand, is based on the addition of a secondary sunshade 20 and the configuration of the secondary sunshade 20 as an irregularly shaped folding structure. The unfolded edge 201 of the secondary sunshade 20, which is away from the main sunshade 10, swings around the hinge axis of the hinge end toward the side closer to or away from the main sunshade 10, thereby improving the fit of the secondary sunshade 20 with the irregularly shaped window contour and meeting the needs of the usage scenario of full shading for irregularly shaped windows. On the other hand, based on the arrangement of the secondary sunshade 20 and the main sunshade 10 along a first direction X intersecting the height direction Z of the main sunshade 10, the secondary sunshade 20 and the main sunshade 10 are arranged in a first direction X. The transmission component 31 drives the main sunshade 10 and the secondary sunshade 20 to sequentially close or unfold along a preset trajectory S, so that both the main sunshade 10 and the secondary sunshade 20 are stored on one side of the window, reducing the occupation of the roof space inside the vehicle, improving the transparency of the interior view, and allowing the user to stop the sunshade assembly 220 in any position, improving the accuracy of blocking glare from specific angles, as well as enhancing the user experience, sense of luxury, and aesthetics; on the other hand, the secondary sunshade 20 is linked to the transmission component 31 through the linkage component 32, thereby reducing structural components, improving space utilization, and saving costs.

[0055] For the sake of accuracy, all references to direction in this article should be indicated by [reference needed]. Figure 2 For reference, the term "first direction X" refers to the arrangement direction of the front and rear wheels of vehicle 1000, that is... Figure 2 The left and right directions. The term "second direction Y" refers to the direction in which the outer contour of the irregular area of ​​the window extends, or the direction in which the contour line of the movable end of the secondary sunshade 20 extends after it is unfolded, that is... Figure 2 The arc-shaped direction. The term "height direction Z" refers to the arrangement direction from the chassis to the roof of the vehicle 1000, that is... Figure 2The vertical direction. The first direction X, the second direction Y, and the height direction Z can be customized according to the specific structure of the product and the viewing angle presented in the accompanying drawings; this application embodiment does not impose specific limitations. For example, in this embodiment, the first direction X is perpendicular to the height direction Z and intersects with the second direction Y. Of course, in some embodiments, the first direction X and the height direction Z can also be set at an acute or obtuse angle; this application embodiment does not impose specific limitations.

[0056] Please refer to the following: Figures 2 to 4 , Figure 4 yes Figure 2 The diagram shows the structure of the second part of the sunshade assembly 220. The transmission mechanism 30 includes a transmission component 31 and a linkage component 32. One end of the linkage component 32 is connected to the transmission component 31, and the other end is connected to the unfolding edge 201. The transmission component 31 is connected to the top and / or bottom of the main sunshade 10. The drive mechanism 60 is used to drive the transmission component 31 to drive the main sunshade 10 and the secondary sunshade 20 to close or unfold sequentially along a preset trajectory. Thus, the transmission connection between the main sunshade 10 and the secondary sunshade 20 is realized through the linkage component 32. Therefore, by setting up a drive mechanism 60, the closing and unfolding of the main sunshade 10 and the secondary sunshade 20 can be realized, reducing the number of components, saving costs, and improving the structural compactness of the sunshade assembly 220.

[0057] For example, in this embodiment, the preset trajectory S includes a first trajectory S1 and a second trajectory S2. The second trajectory S2 intersects with and is continuous with the first trajectory S1. The transmission member 31 is used to drive the linkage member 32 to close the secondary sunshade 20 along the second direction Y, and to drive the top and / or bottom of the main sunshade 10 to move the secondary sunshade 20 and / or the bottom along the first direction X after the secondary sunshade 20 is closed, so as to close the main sunshade 10. The transmission member 31 is also used to drive the top and / or bottom of the main sunshade 10 to move the secondary sunshade 20 and / or the bottom along the first direction X to unfold the main sunshade 10, and to drive the linkage member 32 to unfold the secondary sunshade 20 along the second direction Y after the main sunshade 10 is unfolded, wherein the first direction X is parallel to the first trajectory S1, and the second direction Y intersects with and is parallel to the second trajectory S2, and intersects with the first direction X. Therefore, based on the setting that the main sunshade 10 and the secondary sunshade 20 close or open in different directions, and the sunshade assembly 220 integrates the two different directional movements into a control sequence controlled by a single transmission component 31, on the one hand, a single power source can achieve complex functions, reducing costs and failure rates, and enabling the sunshade assembly 220 to cover irregularly shaped windows, achieving a complete and blind-spot-free shielding effect; on the other hand, the main sunshade 10 and the secondary sunshade 20 are controlled to close or open sequentially, thereby ensuring that the movement trajectories of the main sunshade 10 and the secondary sunshade 20 do not collide or jam with each other in time and space. The control system of the sunshade assembly 220 The main sunshade 10 and the secondary sunshade 20 are driven in only one direction at any given time, which improves the stability of the load on the control system, reduces the requirements of the control system and transmission system, and improves the reliability and stability of the main sunshade 10 and the secondary sunshade 20 in closing or releasing. On the other hand, after the secondary sunshade 20 is closed, it can move synchronously in the first direction X at the same time as the main sunshade 10 closes in the first direction X. This allows the secondary sunshade 20 and the main sunshade 10 to be compactly stored in a corner of the window after being fully closed, thereby reducing the encroachment of the sunshade assembly 220 on the interior space and field of vision, making the interior design of the vehicle simpler and more open.

[0058] It should be noted that the sequential closing or opening of the main sunshade 10 and the secondary sunshade 20 includes the sequential closing or opening of the main sunshade 10 and the secondary sunshade 20 as a whole. The closing or opening sequence of the main sunshade 10 and the secondary sunshade 20 can be relatively continuous, rather than absolutely continuous. For example, the operation of the sequential closing or opening of the main sunshade 10 and the secondary sunshade 20 is as follows: During the closing movement, the end of the secondary sunshade 20 furthest from the main sunshade 10 closes towards the end of the main sunshade 10 furthest from the secondary sunshade 20; conversely, during the opening movement, the end of the main sunshade 10 furthest from the secondary sunshade 20 opens towards the end of the secondary sunshade 20 furthest from the main sunshade 10. During the process of the secondary sunshade 20 completing or nearly completing its closing, the closing movement of the main sunshade 10 is initiated simultaneously. The main sunshade 10 is used to cover the first area of ​​the glass body 210, and the secondary sunshade 20 is used to cover the second area of ​​the glass body 210.

[0059] For example, in this embodiment, both the main sunshade curtain 10 and the secondary sunshade curtain 20 are configured as foldable curtains, meaning they are stored by folding. Of course, in some embodiments, the main sunshade curtain 10 can be configured as a roll-up curtain, and the secondary sunshade curtain 20 as a foldable curtain. A roll-up curtain refers to a curtain section that is rolled up and stored using a roller. The structure of the main sunshade curtain 10 and the secondary sunshade curtain 20 can be set according to actual conditions, and this embodiment does not impose specific limitations.

[0060] In this embodiment, for example, the transmission component 31 includes a first transmission structure 311 and a second transmission structure 312 independently disposed from the first transmission structure 311. The first transmission structure 311 is connected to the top of the main sunshade 10 and is used to pull the top of the main sunshade 10 to move the top of the secondary sunshade 20 along the first direction X. The second transmission structure 312 is connected to the bottom of the main sunshade 10 and is used to pull the bottom of the main sunshade 10 to move the bottom of the secondary sunshade 20 along the first direction X. Therefore, by using a transmission component 31 that includes an independently configured first transmission structure 311 and a second transmission structure 312 to drive the main sunshade 10 and the secondary sunshade 20 to close or open, on the one hand, the problem of curtain tilting, wrinkling, or even jamming during the closing or opening movement of a single transmission structure is avoided, thus improving the reliability and stability of the main sunshade 10 and the secondary sunshade 20 in closing or opening; on the other hand, the first transmission structure 311 and the second transmission structure 312 are respectively connected to the top and bottom of the main sunshade 10, thereby enabling the main sunshade 10 and the secondary sunshade 20 to move synchronously up and down as a whole, rather than moving in a twisting manner, thereby improving the accuracy of the main sunshade 10 and the secondary sunshade 20 in conforming to the curvature of the glass body 210 during movement, and improving the reliability and smoothness of the main sunshade 10 and the secondary sunshade 20 moving along the first direction X; furthermore, the first transmission structure 311 and the second transmission structure 312 can share the load, reducing wear and extending the service life of the entire sunshade assembly 220 system.

[0061] For example, in this embodiment, the first transmission structure 311, the second transmission structure 312, and the linkage 32 are all configured as flexible ropes. Therefore, on the one hand, the flexible ropes improve the wiring flexibility of the first transmission structure 311 and the second transmission structure 312; on the other hand, the flexible ropes are lighter than rigid ropes such as steel wire ropes, reducing the inertia of moving parts, improving the control accuracy of the closing or opening movements of the main sunshade 10 and the secondary sunshade 20, and the material of the flexible rope itself has a damping effect, thereby absorbing and attenuating vibrations and impacts from the driving source or driven parts, reducing noise during system operation, and protecting precision components from vibration damage. The flexible rope can be, but is not limited to, polymer fiber ropes, Kevlar ropes, and nylon ropes. Of course, in some embodiments, at least one of the first tensioning, second transmission structure 312, and linkage 32 can also be configured as a steel rope; this application does not specifically limit this. A rigid rope includes, but is not limited to, at least one of steel wire ropes or steel cables.

[0062] It should be noted that a rigid rope refers to a rope made of a rigid material. Rigid materials can be high-strength and low-elongation materials, such as metals or metal alloys. A flexible rope refers to a rope made of a flexible material, such as natural fibers or synthetic fibers. The distinction between rigid and flexible ropes can also be based on elastic elongation; for example, a rope with an elastic elongation greater than or equal to 5% is considered a flexible rope, and a rope with an elastic elongation less than 5% is also considered a flexible rope. The choice between flexible and rigid ropes can be made according to specific circumstances, and this application does not impose specific limitations.

[0063] In one possible implementation, the transmission mechanism 30 further includes a first pushing member 33 and a second pushing member 34. The first pushing member 33 is fixedly connected to the first transmission structure 311. The linkage member 32 is arranged parallel to the first transmission structure 311 in the height direction Z on the first pushing member 33. The second pushing member 34 is fixedly connected to the second transmission structure 312. The secondary sunshade 20 includes a secondary curtain body 21 and a hinge shaft 22. The secondary curtain body 21 is rotatably connected to the hinge shaft 22. The main sunshade 10 includes a main curtain body 11 and a first stop body 12. The first stop body 12 is fixedly connected to the main curtain body 11, and the first pushing member 33 is used to push the first stop body 12 to drive the main curtain body 11 together with the secondary curtain body 21 to move along the first direction X toward the side opposite to the secondary sunshade 20. The second pushing member 34 is located on the side of the hinge shaft 22 away from the secondary sunshade 20, and is used to push the hinge shaft 22 to drive the secondary curtain body 21 together with the main curtain body 11 to move along the first direction X toward the side facing the secondary sunshade 20. Therefore, on the one hand, the first transmission structure 311 and the second transmission structure 312 directly apply the thrust to the first stop body 12 and the second stop body 13, which are fixedly connected to the main curtain body 11, through the first push member 33 and the second push member 34, respectively. This improves the utilization rate of the driving force and thus improves the reliability and smoothness of the main sunshade 10 and the secondary sunshade 20 moving along the preset trajectory S. On the other hand, the first transmission structure 311 and the second transmission structure 312 are decoupled in motion, and the entire system can automatically complete the movement in opposite directions. This avoids the problem of interference between the first push member 33 and the second push member 34 during movement, simplifies the management difficulty of the control algorithm, and makes the structure of the entire transmission mechanism 30 simple and compact, making it easy to hide in the narrow space of the interior panel. Furthermore, the linkage member 32 and the first transmission structure 311 are arranged in parallel on the first push member 33 in the height direction Z, thereby avoiding the linkage member 32 interfering with the movement of the first transmission structure 311. For example, in this embodiment, the first pushing member 33, the second pushing member 34, the first stop body 12 and the hinge shaft 22 are all configured as rigid structures, thereby improving the quality of force transmission.

[0064] In some embodiments, the main sunshade 10 further includes a second stop 13, which is fixedly connected to the first stop 12 on both sides of the main curtain body 11 in the height direction Z of the main curtain body 11; the second pusher 34 is also used to push the second stop 13 to drive the main curtain body 11 together with the secondary curtain body 21 to move along the first direction X toward the side opposite to the secondary sunshade 20; and / or, the transmission mechanism 30 further includes a third pusher 35, which is disposed on both sides of the hinge shaft 22, and the third pusher 35 is used to push the hinge shaft 22 to drive the secondary curtain body 21 together with the main curtain body 11 to move along the first direction X toward the side opposite to the secondary sunshade 20. Therefore, the arrangement of the second stop 13 and the third pusher 35 enables the top and bottom of the main curtain body 11 to move synchronously along the first direction X, preventing the main curtain body 11 from twisting and moving. This improves the accuracy of the main sunshade 10 and the secondary sunshade 20 in conforming to the curvature of the glass body 210 when they move, and also improves the reliability and smoothness of the movement of the main sunshade 10 and the secondary sunshade 20 along the first direction X.

[0065] The distance between the first stop 12 closest to the secondary sunshade 20 and the fixed edge 202 of the secondary sunshade 20 along the first direction X is greater than the distance between the second stop 13 closest to the secondary sunshade 20 and the fixed edge 202 of the secondary sunshade 20 along the first direction X. As a result, the main sunshade 10 can provide a preset length of clearance for the first push member 33 at the top, so that the first push member 33 can pull the linkage member 32 to drive the secondary curtain 21 to close towards the side of the main curtain 11, and at the same time realize the folding of the main sunshade 10 after the secondary sunshade 20 is folded.

[0066] The number of first stop bodies 12 is set to multiple, and the multiple first stop bodies 12 are arranged at intervals along the first direction X; and / or, the number of second stop bodies 13 is set to multiple, and the multiple second stop bodies 13 are arranged at intervals along the first direction X. Thus, the first pushing member 33, the second pushing member 34, and the third pushing member 35 can evenly distribute the pushing force on the multiple first stop bodies 12 and the multiple second stop bodies 13. On the one hand, this prevents the main curtain body 11 from twisting and deviating when moving along the first direction X; on the other hand, the arrangement of the multiple first stop bodies 12 and the multiple second stop bodies 13 can be used to guide the main curtain body 11 to fold or unfold in an orderly manner.

[0067] The number of first stop bodies 12 may be the same as or different from the number of second stop bodies 13. For example, multiple first stop bodies 12 and multiple second stop bodies 13 may be arranged asymmetrically. Specifically, the number of first stop bodies 12 may be less than the number of second stop bodies 13, so that the main curtain body 11 can provide a preset length of clearance for the first pushing member 33 at the top, so that the first pushing member 33 can pull the linkage member 32 to drive the secondary curtain body 21 to close towards one side of the main curtain body 11. In some embodiments, the number of first stop bodies 12 may also be equal to the number of second stop bodies 13, which is not specifically limited in this application embodiment.

[0068] The number of first stop bodies 12 may be less than the number of second stop bodies 13. Parts of the multiple first stop bodies 12 and multiple second stop bodies 13 are aligned one-to-one in the height direction Z, thereby improving the flatness and smoothness of the main sunshade 10 after folding. Of course, in some embodiments, parts of the multiple first stop bodies 12 and multiple second stop bodies 13 are staggered in the height direction Z; this application does not impose specific limitations on this.

[0069] Please refer to the following: Figure 2 , Figure 3 and Figure 4In this embodiment, for example, the sunshade assembly 220 further includes a first magnetic element 41 and a second magnetic element 42. The first magnetic element 41 is disposed on the side of the main sunshade 10 near the secondary sunshade 20 in the first direction X. The second magnetic element 42 is disposed on the side of the secondary sunshade 20 near the main sunshade 10 in the first direction X. The magnetism of the second magnetic element 42 is repulsive to the magnetism of the first magnetic element 41, and the repulsive force between the second magnetic element 42 and the first magnetic element 41 is less than the transmission force of the transmission element 31. Therefore, during the process of the folded main sunshade 10 and secondary sunshade 20 moving from the closed state to the unfolded state, when the secondary sunshade 20 reaches the position where the main sunshade 10 is fully unfolded, the pulling force of the first transmission structure 311 on the linkage 32 towards the side opposite to the secondary sunshade 20 disappears. The secondary sunshade 20 can move along the second direction Y towards the side opposite to the main sunshade 10 under the repulsive force generated between the first magnetic element 41 and the second magnetic element 42, thereby realizing the secondary sunshade 20 moving from the closed state to the unfolded state. On the other hand, the repulsive force between the second magnetic element 42 and the first magnetic element 41 is less than the transmission force of the transmission element 31, thereby realizing the transmission element 31 driving the linkage 32 to move the secondary sunshade 20 to perform the folding and unfolding movements, and reducing the risk of the transmission element 31 breaking under the action of repulsive force. Understandably, since the hinge shaft 22 is located at the bottom of the junction between the secondary sunshade 20 and the main sunshade 10, after the secondary sunshade 20 swings at a preset angle under the action of repulsion, it can also move to the fully unfolded position under the action of gravity, saving energy and cost. The linkage 32 can be configured as a rigid rope or a flexible rope. Both ends of the linkage 32 are movably connected to the transmission member 31 and the unfolding edge 201, respectively; or, both ends of the linkage 32 are fixedly connected to the transmission member 31 and the unfolding edge 201, respectively; or, one end of the linkage 32 is movably connected to the transmission member 31, and the other end of the linkage 32 is fixedly connected to the unfolding edge 201; or, one end of the linkage 32 is movably connected to the unfolding edge 201, and the other end of the linkage 32 is fixedly connected to the transmission member 31. Specifically, the linkage 32 is movably inserted through the first pushing member 33 and the secondary curtain body 21. Both the first magnetic element 41 and the second magnetic element 42 can be configured as magnets or electromagnets, and the embodiments of this application do not specifically limit them.

[0070] Understandably, the repulsive force generated between the first magnetic element 41 and the second magnetic element 42 will cause a gap to form between the main sunshade 10 and the secondary sunshade 20 at their junction. Exemplarily, in this embodiment, the main curtain body 11 and the secondary curtain body 21 can also be arranged adjacent to each other or spaced apart by a preset distance at the junction of the main sunshade 10 and the secondary sunshade 20. Therefore, since the repulsive force generated between the first magnetic element 41 and the second magnetic element 42 is relatively small, the gap formed between the main curtain body 11 and the secondary curtain body 21 is also relatively small, and the impact of this gap on the shading effect can be ignored; that is, this gap will not cause a serious light leakage problem.

[0071] Of course, in some embodiments, in order to overcome the risk of a gap between the main sunshade 10 and the secondary sunshade 20 caused by the repulsive force generated between the first magnetic element 41 and the second magnetic element 42, the main curtain body 11 and the secondary curtain body 21 are overlapped at the junction of the main sunshade 10 and the secondary sunshade 20, so that there is no gap between the main sunshade 10 and the secondary sunshade 20 at the junction, thereby improving the full shading effect of the sunshade assembly 220 and providing the shading effect of the sunshade assembly 220.

[0072] Please refer to the following: Figure 3 and Figure 5 , Figure 5 yes Figure 2 The diagram shows the structure of the third part of the sunshade assembly 220. The first pushing member 33 has a through hole 3301. Limiting heads 321 are provided at both ends of the linkage member 32. The linkage member 32 passes through the through hole 3301, and the limiting heads 321 are located outside the through hole 3301, stopping against the first pushing member 33. Of course, in some embodiments, the limiting heads 321 can be omitted, i.e., the linkage member 32 is fixed inside the through hole 3301 by adhesive, snap-fit, or other means; or, the first pushing member 33 and the linkage member 32 are integrally formed.

[0073] In some embodiments, the linkage 32 is configured as a rigid rope, with one end of the linkage 32 fixedly connected to the transmission member 31 and the other end of the linkage 32 fixedly connected to the unfolding edge 201. Thus, during the process of the folded main sunshade 10 and secondary sunshade 20 moving from the closed state to the unfolded state, when the secondary sunshade 20 reaches the fully unfolded position of the main sunshade 10, the pulling force exerted by the first transmission structure 311 on the linkage 32 towards the side opposite to the secondary sunshade 20 disappears. The secondary sunshade 20, under the driving force exerted by the first transmission structure 311 on the linkage 32 towards the side of the secondary sunshade 20, pushes against the unfolding edge 201 and moves away from the main sunshade 10 along the second direction Y, thereby realizing the secondary sunshade 20 moving from the closed state to the unfolded state.

[0074] Please refer to the following: Figure 3 and Figure 6 , Figure 6 yes Figure 2 A schematic diagram of the fourth part of the sunshade assembly 220 is shown. In some embodiments, the secondary curtain body 21 is configured as an elastic curtain 211; or, the secondary curtain body 21 is provided with an elastic curtain 211, which is elastically extended and retracted between the hinge end and the movable end. Thus, by setting the elastic curtain 211 elastically extended and retracted between the hinge end and the movable end of the secondary sunshade 20, the secondary curtain body 21 can adaptively adjust the size from the hinge end to the movable end based on the shape of the second region, thereby improving the fit between the contour edge of the secondary curtain body 21 at the movable end and the arc or curve of the window contour, thereby achieving a seamless and full-coverage effect.

[0075] In some embodiments, the secondary sunshade 20 further includes a swing arm 23. The swing arm 23 is disposed on the secondary curtain body 21. The swing arm 23 is configured as an elastic body 231; or, the swing arm 23 is provided with an elastic body 231. Wherein, the extension and contraction direction of the elastic body 231 is the same as the extension direction of the swing arm 23. Therefore, based on the provision of a swing arm 23 on the secondary sunshade 20, and the configuration of the swing arm 23 as an elastic body 231; or, the provision of an elastic body 231 on the swing arm 23, and the extension and retraction direction of the swing arm 23 being the same as the extension direction of the swing arm 23, on the one hand, the swing arm 23 can act as a lever to transmit and amplify the extension and retraction movement of the elastic body 231 to the edge of the sunshade 20, thereby continuously applying a soft, resilient pressure to the side wall of the window or guide rail, so that the secondary curtain body 21 can adaptively adjust the size from the hinge end to the movable end based on the shape of the second region, thereby improving the fitting effect of the contour edge of the secondary curtain body 21 at the movable end with the arc or curve of the window contour, achieving a no-dead-angle and full-coverage effect.

[0076] Exemplarily, in this embodiment, the swing arm 23 includes two swing rods 232. An elastic body 231 is connected between the two swing rods 232. One end of the swing rod 232 facing away from the elastic body 231 is hinged to the hinge shaft 22, and the other end of the swing rod 232 facing away from the elastic body 231 is fixedly connected to the secondary curtain body 21. Thus, the two swing rods 232 can transmit the elastic force generated by the elastic body 231, thereby providing stable and reliable lateral pressure to the secondary curtain body 21, optimizing the force distribution on the swing arm 23, and protecting the swing rods 232 and other rigid components. Of course, in some embodiments, the swing arm 23 can be configured as an integral elastic structure; this embodiment does not specifically limit this. The elastic body 231 can be configured as a spring, sheet metal, etc.

[0077] At least a portion of the swing arm 23 located at the fixed edge 202 of the secondary curtain body 21 is configured as a magnetic structure. Specifically, the two swing rods 232 of the swing arm 23 located at the fixed edge 202 of the secondary curtain body 21 are configured as magnetic structures and serve as second magnetic elements 42. Thus, the swing arm 23 and the second magnetic element 42 are integrated into a single structure, thereby reducing the number of structural components, saving costs, and improving the compactness of the sunshade assembly 220. Of course, in some embodiments, the second magnetic element 42 and the swing arm 23 can be independently configured; this application does not impose specific limitations on these embodiments.

[0078] The number of swing arms 23 is set to multiple. At least two swing arms 23 are respectively set on the fixed edge 202 and unfolded edge 201 of the secondary sunshade 20 near the main sunshade 10. Thus, the swing arms 23 set on both sides of the edge can stretch the secondary curtain on both sides of the edge of the movable end, so that the secondary curtain body 21 can better cover the second area, improve the fitting effect of the contour edge of the secondary curtain body 21 at the movable end with the arc or curve of the window contour, and achieve a blind-angle and full-coverage effect. Exemplarily, in this embodiment, the number of swing arms 23 is set to two, so as to avoid the swing arms 23 interfering with the closing movement of the secondary sunshade 20 along the second direction Y.

[0079] Of course, in some embodiments, the number of swing arms 23 is set to one. The swing arm 23 is disposed near the fixed edge 202 or unfolded edge 201 of the secondary sunshade 20 close to the main sunshade 10, thereby avoiding interference of the swing arm 23 with the closing movement of the secondary sunshade 20 along the second direction Y. In other embodiments, the swing arm 23 is disposed in the middle position between the fixed edge 202 and the unfolded edge 201 of the main sunshade 10 close to the secondary sunshade 20, so that the secondary curtain body 21 can better cover the second area, improving the fit between the contour edge of the secondary curtain body 21 at the moving end and the arc or curve of the window contour, achieving a no-dead-angle and full-coverage effect.

[0080] Please refer to the following: Figures 7 to 9 , Figure 7 yes Figure 2 A first-view cross-sectional view of the sunshade assembly 220 in the middle; Figure 8 yes Figure 2 A cross-sectional view of the sunshade assembly 220 from a second perspective; Figure 9 yes Figure 2A schematic diagram of the fifth part of the sunshade assembly 220 is shown. Exemplarily, in this embodiment, the sunshade assembly 220 further includes a frame 50. A guide channel 501 is provided within the frame 50, and at least a portion of the transmission member 31, at least a portion of the linkage member 32, and the hinge shaft 22 are slidably disposed within the guide channel 501. Thus, the guide channel 501 provides guidance for the movement of the transmission member 31, the linkage member 32, and the hinge shaft 22, improving the smoothness and reliability of the rolling and unrolling movements of the main sunshade 10 and the secondary sunshade 20.

[0081] For example, in this embodiment, the transmission member 31, the linkage member 32, the hinge shaft 22, the first stop body 12, the second stop body 13, the first push member 33, the second push member 34, and the third push member 35 are all slidably disposed within the guide channel 501. The first stop body 12 is configured as a hook, and the main curtain body 11 is mounted on the frame 50 via the hook.

[0082] In some embodiments, the secondary sunshade 20 further includes at least one bearing member 25, which is sleeved on the outside of the hinge shaft 22 and movably disposed within the guide channel 501. The bearing member 25 reduces the friction between the hinge shaft 22 and the frame 50, improving the smoothness and reliability of the secondary sunshade 20 moving along the first direction X with the main sunshade 10. Exemplarily, in this embodiment, the number of bearing members 25 is set to two, with the two bearing members 25 respectively disposed at both ends of the hinge shaft 22.

[0083] In some embodiments, the transmission member 31 and the linkage member 32 are spaced apart within the guide channel 501, and the transmission member 31 and the hinge shaft 22 are also spaced apart within the guide channel 501. This avoids the problem of motion interference between the transmission member 31 and the curtain cord, improving the smoothness and reliability of the movement of the main sunshade 10 and the secondary sunshade 20 along the first direction X. Specifically, the guide channel 501 includes a first channel 5011 and a second channel 5012. The first channel 5011 is located above the second channel 5012 in the height direction Z of the main sunshade 10. The first transmission structure 311 and the linkage member are both movably inserted into the first channel 5011 and spaced apart in the height direction of the main sunshade 10; the first transmission structure 311 and the hinge shaft are both movably inserted into the second channel 5012 and spaced apart in the height direction of the main sunshade 10.

[0084] Exemplarily, in this embodiment, the first channel 5011 includes a first track 50111 and two second tracks 50112. The first track 50111 is located on the side of the two second tracks 50112 near the main sunshade 10, and the first track 50111 communicates with the second track 50112 near the main sunshade 10 and the external environment. A linkage 32 is movably inserted in the first track 50111, and a first transmission structure 311 is movably inserted in the two second tracks 50112. The second channel 5012 includes a third track 50121 and two fourth tracks 50122. The third track 50121 is located on the side of the two fourth tracks 50122 near the main sunshade 10, and the third track 50121 communicates with the second track 50112 near the main sunshade 10 and the external environment. The hinge shaft 22 is movably inserted into the third track 50121, and the first transmission structure 311 is movably inserted into the two fourth tracks 50122. Thus, by connecting and separating the first track 50111 and the second track 50112, on the one hand, the first transmission structure 311 and the linkage 32, and the second transmission structure 312 and the hinge shaft 22, do not interfere with each other during transmission. Simultaneously, the first transmission structure 311 and the linkage 32 are connected via the same first pushing member 33, and the second transmission structure 312 pushes the hinge shaft 22 via the second pushing member 34 and the third pushing member 35. This allows for the arrangement of different components within the limited space of the guide channel 501, resulting in a simple and compact structure. On the other hand, the first track 50111, the second track 50112, the third track 50121, and the fourth track 50122 can provide guidance for the corresponding components, thereby improving the smoothness and reliability of the movement of the main sunshade 10 and the secondary sunshade 20 along the first direction X.

[0085] It should be noted that the structures of the first channel 5011 and the second channel 5012 can be the same or different. The structures of the first channel 5011 and the second channel 5012 can be similar or completely different. The structures of the first channel 5011 and the second channel 5012 can be set according to actual conditions, and this application embodiment does not impose specific limitations. For example, in this embodiment, the two second tracks 50112 are both approximately cylindrical in shape to match the shape of the first transmission structure-311; one of the two fourth tracks 50122 is approximately prismatic in shape to match the shape of the third pushing member 35, and the other of the two fourth tracks 50122 is approximately cylindrical in shape to match the shape of the second transmission structure 312.

[0086] The transmission mechanism 30 also includes a plurality of first pulleys 36 and a plurality of second pulleys 37. The plurality of first pulleys 36 and the plurality of second pulleys 37 are rotatably mounted on the frame 50. A first transmission structure 311 is rotatably sleeved on the outside of the plurality of first pulleys 36, and a second transmission structure 312 is rotatably sleeved on the outside of the plurality of second pulleys 37. Thus, on the one hand, the plurality of first pulleys 36 and the plurality of second pulleys 37 can guide the first transmission structure 311 and the second transmission structure 312 to move in a specified direction, improving the smoothness and reliability of the movement of the main sunshade 10 and the secondary sunshade 20 along the first direction X; on the other hand, the plurality of first pulleys 36 and the plurality of second pulleys 37 can respectively divide the first transmission structure 311 and the second transmission structure 312 into short-span line segments, thereby reducing the vibration and sagging of the first transmission structure 311 and the second transmission structure 312 within a single span, and reducing the friction between the first transmission structure 311 and the second transmission structure 312 and the frame 50, extending the service life of the transmission mechanism 30.

[0087] In some embodiments, the frame 50 includes a plurality of supports 51 and a plurality of connectors 52. Each connector 52 is fixedly connected between two adjacent supports 51. A plurality of first pulleys 36 and a plurality of second pulleys 37 are rotatably mounted on different connectors 52. Thus, on the one hand, by modularizing the frame 50, the processing difficulty of the frame 50 is reduced, and the frame 50 is made suitable for flexible assembly of different shapes, reducing maintenance difficulty; on the other hand, by rotatably mounting the plurality of first pulleys 36 and the plurality of second pulleys 37 on different connectors 52, the installation position and installation angle of each first pulley 36 and second pulley 37 can be independently and precisely designed and controlled, thereby ensuring that the plurality of first pulleys 36 and the plurality of second pulleys 37 can be perfectly aligned, reducing friction and wear, and the connectors 52 act as reinforcing ribs between adjacent supports 51, preventing the frame 50 from deforming under long-term, repeated tension on the transmission component 31, and facilitating the positioning and assembly of the various parts of the sunshade assembly 220.

[0088] Please refer to it again. Figure 1 , Figure 2 and Figure 9In this embodiment, the multiple brackets 51 include a first bracket 511, a second bracket 512, a third bracket 513, and a fourth bracket 514. The first bracket 511, second bracket 512, third bracket 513, and fourth bracket 514 are connected by multiple connectors 52 to form a light-transmitting area. The extension direction of the first bracket 511 is parallel to the extension direction of the second bracket 512 and parallel to the first direction X, thereby improving the smoothness and reliability of the movement of the main sunshade 10 and the secondary sunshade 20 along the first direction X. The extension direction of the third bracket 513 is parallel to the second direction Y. The third bracket 513 is configured with an arc-shaped structure. The guide channel 501 provided in the third bracket 513 is also configured with an arc-shaped structure, thereby guiding the secondary sunshade 20 to fit the irregularly shaped window contour, meeting the needs of scenarios requiring full shading of irregularly shaped windows. Of course, in some embodiments, at least two of the multiple brackets 51, including the first bracket 511, second bracket 512, third bracket 513, and fourth bracket 514, are integrated into a single structure. For example, the first bracket 511 and the fourth bracket 514 are integrated into a single structure. The number and arrangement of the brackets 51 can be set according to the shape of the vehicle window of the vehicle 1000, and this embodiment does not impose specific limitations.

[0089] The material of frame 50 may include, but is not limited to, aluminum, plastic, etc. The plastic may be, but is not limited to, a composite material of polypropylene and glass confinement or a composite material of nylon and glass confinement.

[0090] For example, in this embodiment, the drive mechanism 60 drives the transmission component 31 to move the linkage component 32. This enables the sunshade assembly 220 to intelligently close and open, ensuring consistent and accurate operation and improving the user experience. Of course, in some embodiments, the drive mechanism 60 can be omitted, meaning the user can directly operate the transmission component 31 manually to drive the linkage component 32 to close or open the main sunshade 10 and the secondary sunshade 20.

[0091] In some embodiments, the drive mechanism 60 includes a first drive motor 61 and a second drive motor 62. The first drive motor 61 is connected to the first transmission structure 311 and is used to drive the first transmission structure 311 to rotate. The second drive motor 62 is connected to the second transmission structure 312 and is used to drive the second transmission structure 312 to rotate. This decoupling of the transmission between the first transmission structure 311 and the second transmission structure 312 is achieved, enabling the main sunshade 10 and the secondary sunshade 20 to adapt to the edge contour of the curved window and simplifying some mechanical structures. Of course, in some embodiments, the number of drive motors may be set to only one.

[0092] It should be noted that the first drive motor 61 and the second drive motor 62 can work alternately or synchronously during the closing or opening of the main sunshade 10 and the secondary sunshade 20. This application embodiment does not make specific limitations.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
