DETAILED DESCRIPTION

[0027] In order to enable persons skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by persons skilled in the art without creative work fall within the scope of protection of the present application.

[0028] The terms "first", "second", etc. in the specification and claims of the present application and the above-described drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but can optionally include steps or units not listed, or can optionally include other steps or units inherent to the process, method, product or device.

[0029] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearance of the phrase in various places in the specification does not necessarily all refer to the same embodiment, nor is it necessarily mutually exclusive of other embodiments. It is explicitly and implicitly understood that the embodiments described herein can be combined with other embodiments.

[0030] Please refer to Figures 1-3 , Figure 1This is a schematic diagram of the structure of the sunshade assembly in some embodiments of this application. Figure 2 This is a schematic diagram of the through-channel structure in some embodiments of this application. Figure 3 This is a schematic diagram of the frame curtain assembly in some embodiments of this application. In some embodiments, the sunshade assembly 100 includes a transparent panel 110, a first crossbeam 120, a first frame curtain assembly 201, a first transmission component 145, a second frame curtain assembly 202, and a second transmission component 146. The transparent panel 110 includes a first panel area 101 and a second panel area 102. The first crossbeam 120 is integrally formed with the transparent panel 110, and the first crossbeam 120 contains a first driving mechanism 131 and a second driving mechanism 132. Figure 2 As shown, the first crossbeam 120 is also provided with a first set of through channels 147 and a second set of through channels 148, as follows: Figure 3 As shown, the first frame curtain assembly 201 is disposed corresponding to the first panel area 101; the first transmission component 145 is disposed in the first set of through channels 147, one end of the first transmission component 145 is connected to the curtain 250 of the first frame curtain assembly 201, and the first drive mechanism 131 drives the curtain 250 of the first frame curtain assembly 201 to unfold and cover the first panel area 101 through the first transmission component 145; the second frame curtain assembly 202 is disposed corresponding to the second panel area 102; the second transmission component 146 is disposed in the second set of through channels 148, one end of the second transmission component 146 is connected to the curtain 250 of the second frame curtain assembly 202, and the second drive mechanism 132 drives the curtain 250 of the second frame curtain assembly 202 to unfold and cover the second panel area 102 through the second transmission component 146.

[0031] Thus, the integrated structure of the first crossbeam 120 and the transparent panel 110 reduces the assembly gap of traditional split components, improves the overall structural strength and sealing, reduces the space occupied in the direction perpendicular to the first crossbeam 120, is more suitable for the limited installation space inside the vehicle, and also avoids abnormal noise caused by vibration to a certain extent. In addition, the built-in design of the first drive mechanism 131, the second drive mechanism 132, the first set of through channels 147 and the second set of through channels 148 optimizes the spatial layout, eliminates additional connecting parts, reduces assembly complexity, and improves the stability and reliability of the curtain drive.

[0032] The transparent panel 110 is divided into a first panel area 101 and a second panel area 102, corresponding to the first frame curtain assembly 201 and the second frame curtain assembly 202, and is driven and controlled by the independent first driving mechanism 131, the first transmission assembly 145, the second driving mechanism 132, and the second transmission assembly 146, respectively. This design allows users to individually adjust the deployment or storage state of the curtain 250 according to the light intensity of different areas and the difference in use scenarios (such as the different needs of front and rear passengers), fully meeting the diversified sun-shading needs.

[0033] The first transmission assembly 145 and the second transmission assembly 146 are respectively arranged in the first set of through channels 147 and the second set of through channels 148, which effectively protect and limit the transmission members, reducing wear and tear or jamming problems caused by shaking and friction during transmission. At the same time, the corresponding connection relationship between the driving mechanism and the transmission assembly ensures direct and stable power transmission, reduces transmission loss, and improves the smoothness of the deployment / storage of the curtain 250. In the actual connection of the first transmission assembly 145 arranged in the first set of through channels 147 and the second transmission assembly 146 arranged in the second set of through channels 148, the ends of the two sets of transmission assemblies close to the corresponding driving mechanisms are respectively precisely engaged with the output shafts of the first driving mechanism 131 and the second driving mechanism 132 through the intermediate gear parts. This gear transmission connection mode provides directness and stability guarantee for the power transmission of the two sets, and the intermediate gear, as a transmission bridge, can match the rotation speeds of the output shafts of the first transmission assembly 145 and the first driving mechanism 131, and the output shafts of the second transmission assembly 146 and the second driving mechanism 132, respectively, achieving efficient transmission of the two sets of power and reducing energy loss.

[0034] In addition, the two sets of frame curtain assemblies, transmission assemblies, and driving mechanisms adopt a modular design, with independent functions of each component, which not only facilitates standardized production to reduce costs, but also enables independent maintenance of individual components during later maintenance, and can be flexibly expanded according to the panel area division requirements, with strong adaptability.

[0035] Please refer to Figure 4 , Figure 4Another structural diagram of the sunshade curtain assembly in some embodiments of the present application. The first cross beam 120 is integrally provided with the transparent panel 110, that is, when the PU (polyurethane) of the transparent panel 110 is injected, a cavity of the first cross beam 120 is additionally arranged in the original mold, and when the PU material in a molten state wraps the outer edge structure of the transparent panel 110, the PU material is integrally formed into the main structure of the first cross beam 120 in the corresponding cavity of the first cross beam 120 in the mold, and the PU material of the first cross beam 120 is naturally connected with the PU layer wrapping the edge of the transparent panel 110 as a whole, realizing the integral provision of the first cross beam 120 and the transparent panel 110 through the same PU injection process.

[0036] In some embodiments, when the first cross beam 120 is integrally provided with the transparent panel 110, materials such as polyvinyl chloride (PVC), thermoplastic elastomer (TPE), or ethylene propylene diene rubber (EPDM) can also be used, and structural fusion can also be achieved through precise design of the mold cavity. During the injection molding process, the molten PVC can tightly wrap the edge of the transparent panel 110 and fill the cavity of the first cross beam 120 due to its good fluidity, forming a whole structure with rigidity and toughness; the TPE material, with its thermoplastic properties, maintains the required structural strength of the first cross beam 120 after injection molding, and also has certain aging resistance, reducing the risk of cracking during long-term use; and the EPDM material can form stable chemical bond connections at the edge of the transparent panel 110 through high-temperature vulcanization injection molding process, significantly improving the sealing performance of the whole structure, which can be adapted to outdoor use scenarios such as vehicles. Among them, the injection material can be selected from one or more of the actual needs and application scenarios, which is not specifically limited here.

[0037] Please refer to Figure 5 , Figure 5 A structural diagram of the existing sunshade curtain assembly. As Figure 5 shown, after the first cross beam and the transparent panel are installed, there is at least a gap of more than 6mm between the first cross beam and the transparent panel, and as Figure 4 shown, the first cross beam 120 is integrally provided with the transparent panel 110, thereby realizing zero gap between the first cross beam 120 and the transparent panel 110, thereby reducing the space occupation in the direction perpendicular to the first cross beam 120.

[0038] Furthermore, in traditional structures, the through-channels are typically formed through secondary processing or modular assembly. For example, drilling holes or embedding pipes into the already formed first crossbeam is limited by the mold release angle, and the channel's direction often requires a pre-reserved release slope, making it impossible to achieve an ideal straight layout or precise positioning. Moreover, the channels formed by modular assembly have seams, affecting sealing and the transmission stability of the transmission components. Therefore, by pre-embedding the first set of through-channels 147 and the second set of through-channels 148 before the first crossbeam 120 is injection molded, their position and direction can be precisely controlled, effectively avoiding the aforementioned limitations of the demolding process. Furthermore, there is no need to consider the impact of the release slope on the channel structure and dimensional accuracy, thus providing a smoother and more stable guiding path for the transmission components and reducing running resistance.

[0039] Please see Figure 6 , Figure 6 for Figure 1 The diagram shows a partial enlarged structural schematic of the sunshade assembly. In some embodiments, the sunshade assembly 100 further includes two third crossbeams 150. The two third crossbeams 150 are disposed opposite to the first crossbeam 120 and respectively located in the first panel area 101 and the second panel area 102. The two third crossbeams 150 are integrally formed with the transparent panel 110. Thus, the third crossbeams 150 are integrally formed with the transparent panel 110 through injection molding, forming a stable frame structure, reducing assembly steps and the number of connectors, and effectively improving the overall structural strength and resistance to deformation.

[0040] Please continue reading. Figure 6 In some embodiments, the third crossbeam 150 has an adhesive surface 151 on one side for bonding with the roof. The adhesive surface 151 on one side of the third crossbeam 150 allows for tight adhesion to the roof using high-strength structural adhesive.

[0041] In some embodiments, the adhesive surface 151 can be the adhesive surface of a mushroom-shaped hook and loop fastener, allowing it to be attached to the headliner. For example, the third crossbeam 150 can integrally bond the female hook and loop fastener structure of the mushroom-shaped hook and loop fastener to the adhesive surface 151 by means of integral molding or bonding. During assembly, the headliner component with the corresponding male hook and loop fastener structure is aligned with the adhesive surface 151, and the female and male hook and loop fasteners are tightly connected by pressing. Alternatively, in some embodiments, the third crossbeam 150 can integrally bond the male and female hook and loop fasteners of the mushroom-shaped hook and loop fastener to the adhesive surface 151 by means of integral molding or other methods. During assembly, the male hook and loop fastener of the mushroom-shaped hook and loop fastener is connected to the headliner component by means of bonding or other methods.

[0042] Thus, the third crossbeam 150, through the setting of the adhesive surface 151, makes the connection between the sunshade assembly 100 and the roof more convenient and secure, reducing the complexity of its assembly.

[0043] Please continue to refer to Figure 6 In some embodiments, the sunshade curtain assembly 100 further comprises at least one positioning member 190, which is integrally arranged with the transparent panel 110 and protrudes from the surface of the transparent panel 110, for installation and positioning when the sunshade curtain assembly 100 is installed on the vehicle body.

[0044] Therefore, during the assembly process, the positioning member 190 can be quickly aligned and matched with the pre-set mounting position of the vehicle body, reducing the time-consuming position adjustment during the installation process, ensuring that the sunshade curtain assembly 100 can be accurately fixed on the vehicle body in the designed posture, avoiding functional interference (such as curtain fabric expansion obstruction) caused by installation deviation, and at the same time, the integrated structure strengthens the connection strength of the positioning member 190, guarantees the positioning stability in long-term use, and improves the overall assembly efficiency and reliability.

[0045] Please continue to refer to Figure 2 In some embodiments, the first group of through channels 147 comprises a hollow tubular structure extending along the length direction of the first cross beam 120, for threading the first transmission assembly 145 and providing a guide path for the first transmission assembly 145; the second group of through channels 148 comprises a hollow tubular structure extending along the length direction of the first cross beam 120, for threading the second transmission assembly 146 and providing a guide path for the second transmission assembly 146.

[0046] Therefore, the hollow tubular structure can provide a stable and precise guide path for the first transmission assembly 145 and the second transmission assembly 146, which can effectively avoid friction or interference between the first transmission assembly 145 and the second transmission assembly 146 and other components inside the first cross beam 120, reduce wear and tear, and prolong the service life; at the same time, its through layout along the length direction of the first cross beam 120 makes the wiring of the first transmission assembly 145 and the second transmission assembly 146 more regular, which helps to improve the transmission efficiency of the first drive mechanism 131 and the second drive mechanism 132 on the first transmission assembly 145 and the second transmission assembly 146 respectively, ensures the smooth process of the curtain fabric 250 during the expansion or winding process, and improves the user experience.

[0047] In some embodiments, the hollow tubular structure is a hose structure. By using a hose as the penetrating channel, it can be more closely attached to the inner wall of the first cross beam 120 during the injection molding process, effectively avoiding installation adaptation problems caused by complex structures. At the same time, the hose material can buffer the vibration and friction generated by the movement of the transmission member, reduce the surface wear of the transmission member, and prolong its service life. In addition, the elastic nature of the hose structure can also absorb the noise generated by the movement of the transmission member to some extent, making the curtain driving system run more quietly and smoothly, and significantly improving the user experience.

[0048] Please refer to Figure 7 , Figure 7 for Figure 2 the cross-sectional view of the penetrating channel shown in the figure. In some embodiments, the first group of penetrating channels 147 includes at least two hollow tubular structures, and at least part of the two hollow tubular structures are stacked vertically on the plane where the first cross beam 120 is located, for penetrating different transmission members of the first transmission assembly 145. The second group of penetrating channels 148 includes at least two hollow tubular structures, and at least part of the two hollow tubular structures are stacked vertically on the plane where the first cross beam 120 is located, for penetrating different transmission members of the second transmission assembly 146.

[0049] Among them, at least two hollow tubular structures of the first group of penetrating channels 147 and at least two hollow tubular structures of the second group of penetrating channels 148 are arranged vertically on the plane where the first cross beam 120 is located, so that the independent penetration of multiple transmission members is realized by longitudinal layering, avoiding the space occupation or interference between different transmission members of the first transmission assembly 145 and the second transmission assembly 146 due to horizontal parallel arrangement, and significantly improving the utilization rate of the internal space of the cross beam.

[0050] At the same time, the layered and independent hollow tubular structure provides a dedicated guide path for each transmission member, ensuring that the first transmission assembly 145 and the second transmission assembly 146 do not interfere with each other during movement, effectively reducing the friction and winding risk between transmission members, and ensuring the smoothness and stability of the transmission process. In addition, this layered layout avoids the extra space required for laying multiple transmission members side by side in the length direction of the vehicle, reduces the space occupation in the length direction of the vehicle, releases more space for the arrangement of other parts of the vehicle roof, and facilitates the realization of more compact modular design of the vehicle roof, etc. Among them, the length direction of the vehicle is perpendicular to the hollow tubular structure arranged in the first cross beam 120.

[0051] In some embodiments, please continue to refer to Figure 2The first group of two hollow tubular structures of the penetrating channel 147 is divided into two parts, respectively located on both sides of the first driving mechanism 131; the second group of two hollow tubular structures of the penetrating channel 148 is divided into two parts, respectively located on both sides of the second driving mechanism 132, to avoid the first driving mechanism 131 and the second driving mechanism 132.

[0052] That is, the first group of penetrating channel 147 includes two hollow tubular structures, but each tubular structure is actually divided into two parts by the first driving mechanism 131, respectively located on the left and right sides of the first driving mechanism 131; similarly, the two hollow tubular structures of the second group of penetrating channel 148 are also divided into two parts by the second driving mechanism 132, respectively located on the left and right sides of the second driving mechanism 132.

[0053] Therefore, in terms of actual number, the first group of penetrating channel 147 actually includes four independent hollow tubular structures, which are distributed on both sides of the first driving mechanism 131, two of which are located on one side of the first driving mechanism 131, and the other two are located on the other side of the first driving mechanism 131, which realizes the avoidance of the first driving mechanism 131 through this layout; similarly, the second group of penetrating channel 148 also includes four independent hollow tubular structures, which are distributed on both sides of the second driving mechanism 132.

[0054] The core advantage of this structure design is the maximization of space utilization: the four tubular structures of the first group of penetrating channel 147 are distributed around the first driving mechanism 131, which cleverly avoids the installation space of the driving mechanism in the first cross beam 120, avoiding layout conflicts between components, and realizing independent accommodation of multiple transmission members in the limited cross beam, providing a dedicated penetrating path for different transmission members of the first transmission assembly 145.

[0055] At the same time, the four independent hollow tubular structures ensure the stability and reliability of the transmission process: each transmission member can extend independently through the corresponding side tubular structure, and the transmission path remains continuous from the corresponding driving mechanism output end to the cord fabric 250, reducing transmission loss caused by path intersection or bending; and the closed tubular structure can effectively isolate different transmission members, avoiding friction, winding or jamming problems during movement.

[0056] Please refer to Figure 8 , Figure 8 is a schematic view of the structure of the transparent panel in some embodiments of the present application. In some embodiments, the sunshade curtain assembly 100 further comprises an insert structure 170 which is integrally provided with the transparent panel 110, wherein the insert structure 170 at least comprises a nut.

[0057] When injection molding is performed, the insert structure 170 is pre-positioned in the corresponding position of the mold, and when the injection molding material such as PU, polyvinyl chloride (PVC), thermoplastic elastomer (TPE), or ethylene propylene diene rubber (EPDM) injection molding wraps the edge of the transparent panel 110, the insert structure 170 is simultaneously embedded in the PU layer, so that the nut and the transparent panel 110 form an inseparable whole structure through PU injection molding, wherein the insert structure 170 can be directly used for locking and fixing other components without the need for additional secondary processing on the transparent panel or the PU structure. Therefore, by injection molding the insert structure 170, the damage to the transparent panel or the PU structure caused by later processing is avoided, the connection strength is guaranteed, and the process of separately assembling the bolt is reduced.

[0058] In some embodiments, the driving mechanism is an electric motor, and the output shaft of the electric motor is connected with the corresponding transmission member to drive the curtain fabric 250 to be unfolded or wound on the winding shaft.

[0059] In some embodiments, the driving mechanism is an electric motor, and the output shaft of the electric motor is connected with the corresponding transmission member to drive the curtain fabric 250 to be unfolded or wound on the winding shaft.

[0060] In some embodiments, the driving mechanism is an electric motor, and the output shaft of the electric motor is connected with the corresponding transmission member to drive the curtain fabric 250 to be unfolded or wound on the winding shaft.

[0061] In some embodiments, please refer to Figure 1 and Figure 2 , the first driving mechanism 131 and the second driving mechanism 132 are placed at positions suitable for the direction of the channels passing through the first cross beam 120, the first driving mechanism 131 is arranged beside the extension path of the first group of channels 147, and the output end thereof is connected with the first transmission assembly 145, and the second driving mechanism 132 is arranged beside the extension path of the second group of channels 148, and the output end thereof is connected with the second transmission assembly 146.

[0062] The first driving mechanism 131 and the second driving mechanism 132 are arranged on the side of the extension path of the first group of through channels 147 and the other side of the extension path of the second group of through channels 148, respectively, and are located on the opposite sides of the first group of through channels 147 and the second group of through channels 148.

[0063] In some embodiments, the first driving mechanism 131 is arranged on one side of the extension path of the first group of through channels 147, and the second driving mechanism 132 is arranged on the other side of the extension path of the second group of through channels 148, wherein the first driving mechanism 131 and the second driving mechanism 132 are located on the opposite sides of the first group of through channels 147 and the second group of through channels 148, respectively.

[0064] The first driving mechanism 131 and the second driving mechanism 132 are arranged in a reverse staggered manner: the first driving mechanism 131 is located on one side (such as the left side) of the extension path of the first group of through channels 147, and the second driving mechanism 132 is located on the opposite side (such as the right side) of the extension path of the second group of through channels 148, so that they are located on the opposite sides of the two groups of through channels, respectively, forming a spatial distribution relationship of not approaching each other. This arrangement avoids the centralized arrangement of the two driving mechanisms in the first cross beam 120 by clearly defining the lateral position of the driving mechanism relative to the corresponding channel.

[0065] Therefore, this layout design reduces the risk of spatial interference between the first driving mechanism 131 and the second driving mechanism 132, reserves independent installation space for the two driving mechanisms in the limited cross beam, reduces the structural bulk caused by component stacking, improves the space utilization rate, and further ensures the stability and smoothness of the operation of the sunshade curtain assembly 100.

[0066] Please continue to refer to Figure 2 In some embodiments, the sunshade curtain assembly 100 further comprises an end positioning member 149 arranged in the first cross beam 120 and corresponding to the end of the two groups of through channels, and integrally arranged with the transparent panel 110. The ends of the two hollow tubular structures of the first group of through channels 147 and the two hollow tubular structures of the second group of through channels 148 are connected to the end positioning member 149, respectively.

[0067] The end positioning member 149 is arranged corresponding to the end of the two groups of penetrating channels and is connected with the hollow tubular structure end of the first group of penetrating channels 147 and the second group of penetrating channels 148 respectively, can form accurate positioning and fixing of the end of each tubular structure, avoid displacement and looseness of the penetrating channel due to movement of the transmission assembly or external vibration in long-term use, ensure that the extension path of the penetrating channel always remains stable, and provide reliable guidance for the transmission assembly.

[0068] Meanwhile, the end positioning member 149 and the transparent panel 110 are integrally arranged, which further strengthens the integrity of the internal structure of the first cross beam 120, forms a rigid connection between the penetrating channel and the transparent panel 110 through the end positioning member 149, reduces the assembly gap and relative shaking between components, and improves the structural sealing and firmness of the sunshade curtain assembly 100.

[0069] In some embodiments, the end positioning member 149 and the first group of penetrating channels 147 and the second group of penetrating channels 148 can be integrally designed, that is, they are the same component. Specifically, the end positioning member 149 and the hollow tubular structure of each group of penetrating channels are made by the same forming process to form an integral structure. Thus, the connection gap between the end positioning member 149 and the penetrating channel is eliminated, and they can deform synchronously and bear load cooperatively when stressed, further improving the guidance stability of the transmission assembly, reducing assembly errors, and significantly enhancing the rigidity and durability of the overall structure.

[0070] In addition, the end positioning member 149 is further provided with holes communicating with the holes of each hollow tubular structure. These holes and the hollow parts of the penetrating channels form a continuous channel structure, so that the first transmission assembly 145 and the second transmission assembly 146 can smoothly extend from the penetrating channel to the hole of the end positioning member 149, realizing seamless connection of the transmission path. Thus, the transmission assembly is prevented from being jammed or worn at the connection part of the penetrating channel and the end positioning member 149, ensuring that it always runs stably along the preset path, and also provides a more explicit guidance reference for the installation of the transmission assembly, improving the assembly efficiency, etc.

[0071] Please refer to Figure 9 , Figure 9 for another structural diagram of the penetrating channel in some embodiments of the present application. In some embodiments, the end positioning member 149 further includes a positioning structure 1491 for limiting the end positioning member 149 when it is integrally arranged with the transparent panel 110.

[0072] In the process of integrally arranging the end positioning member 149 with the transparent panel 110, the positioning structure 1491 can effectively limit the installation position of the end positioning member 149, avoid misalignment of the end positioning member 149 and the end portions of the two groups of penetrating channels due to assembly deviation, and ensure that the hollow tubular structure end portions of the first group of penetrating channels 147 and the second group of penetrating channels 148 can be accurately connected with the end positioning member 149, thereby providing a stable path guiding basis for the transmission assembly.

[0073] Meanwhile, the positioning structure 1491 can fix the relative position between the end positioning member 149 and the transparent panel 110, reduce the relative displacement between the two due to vibration and stress during long-term use, and further ensure the stability of the connection between the end portions of the penetrating channels and the end positioning member 149, thereby reducing the friction and jamming risk caused by the position deviation of the penetrating channels during the movement of the transmission assembly.

[0074] Similarly, the corresponding mounting slots of the first driving mechanism 131 and the second driving mechanism 132 are also provided with driving mechanism positioning structures. In the process of assembling the first driving mechanism 131 and the second driving mechanism 132 in the first cross beam 120, the driving mechanism positioning structures can effectively limit the installation positions of the two driving mechanisms, avoid misalignment of the output ends of the driving mechanisms and the transmission assemblies in the corresponding penetrating channels due to assembly deviation, and ensure that the power transmission interfaces of the first driving mechanism 131 and the first transmission assembly 145 and the second driving mechanism 132 and the second transmission assembly 146 are accurately aligned, thereby providing a basis for stable power output.

[0075] Please continue to refer to Figure 9 In some embodiments, the first group of penetrating channels 147 includes a first penetrating sub-channel 1471 and a second penetrating sub-channel 1472. The first penetrating sub-channel 1471 serves as a power pipe for the movement of the first transmission assembly 145 when the curtain is unfolded. The second penetrating sub-channel 1472 serves as a recovery pipe for the recovery and homing guidance of the first transmission assembly 145. The second group of penetrating channels 148 includes a third penetrating sub-channel 1481 and a fourth penetrating sub-channel 1482. The third penetrating sub-channel 1481 serves as a power pipe for the movement of the second transmission assembly 146 when the curtain is unfolded. The fourth penetrating sub-channel 1482 serves as a recovery pipe for the homing guidance of the second transmission assembly 146.

[0076] Please continue to refer to Figure 3In some embodiments, the sunshade curtain assembly 100 further comprises a second cross beam 210, a roller 220, a first fixing seat 231, a second fixing seat 232, a guide rail 240, and a curtain fabric 250, wherein the first fixing seat 231 and the second fixing seat 232 are respectively arranged at two ends of the roller 220 and are respectively connected with the two ends of the roller 220, the guide rail 240 is arranged adjacent to the first fixing seat 231 or the second fixing seat 232 and is arranged opposite to the two ends of the roller 220, and the curtain fabric 250 is wound on the roller 220, wherein one end of the transmission member is connected with the curtain fabric 250, and the other end is used for being penetrated through the corresponding penetration channel to be connected with the output shaft of the corresponding driving mechanism.

[0077] Wherein, the roller 220 is rotatably mounted on the first fixing seat 231 and the second fixing seat 232, ensuring smooth rotation and low resistance; the first fixing seat 231 and the second fixing seat 232 are respectively tightly sleeved on the two ends of the roller 220, realizing stable support and limiting of the roller; the curtain fabric 250 is uniformly and tightly wound on the roller 220, one end of the transmission member is firmly connected with the free end of the curtain fabric 250, the other end is penetrated through the corresponding penetration channel, and the two groups of transmission assemblies close to one end of the corresponding driving mechanism are respectively engaged with the output shafts of the first driving mechanism 131 and the second driving mechanism 132 through the intermediate gear parts.

[0078] Therefore, the structure of the sunshade curtain assembly 100 of the present application makes the installation and disassembly of each component convenient, facilitating production and assembly and later maintenance; for example, when the curtain fabric 250 is damaged, only the first fixing seat 231 and the second fixing seat 232 need to be disassembled for quick replacement, and the vertical layout of the guide rail 240 and the roller 220, combined with the transmission of the transmission member, realizes stable and efficient unwinding and winding of the curtain fabric 250, avoiding deviation or jamming of the curtain fabric 250 during operation.

[0079] Please continue to refer to Figure 9 In some embodiments, at least two fixing seat locking holes 141 are arranged in the first cross beam 120 for respectively locking the first fixing seat 231 and the second fixing seat 232, wherein the fixing seat locking hole 141 is integrally injection molded with the first cross beam 120.

[0080] In some embodiments, please refer to Figure 10 , Figure 10 is the installation schematic diagram of the roller and the fixing seat in some embodiments of the present application. One end of the roller 220 is provided with a core iron 222, and the other end is assembled with a rotating shaft 221, and the two are stably connected through a high-precision concentric shaft sleeve. Wherein, please refer to Figure 11 , Figure 11 is Figure 10 is the enlarged schematic diagram at A, the rotating shaft 221 can be flexibly rotated through the wear-resistant bearing matched with the first fixing seat 231; please refer to Figure 12, Figure 12 For Figure 10 In the enlarged view at B, the core iron 222 can be made of high-strength metal material and tightly embedded with the second fixing seat 232 to ensure the stability of the reel during rotation.

[0081] In the enlarged view at B, the core iron 222 can be made of high-strength metal material and tightly embedded with the second fixing seat 232 to ensure the stability of the reel during rotation.

[0082] Please refer to Figure 13 , Figure 13 For Figure 3 In the enlarged view at B, the core iron 222 can be made of high-strength metal material and tightly embedded with the second fixing seat 232 to ensure the stability of the reel during rotation.

[0083] Thus, through the transmission connection assembly 270, the linear traction force of the first transmission assembly 145 and the second transmission assembly 146 is converted into the smooth sliding of the curtain fabric 250 along the guide rail direction. Compared with the direct connection of the transmission member and the curtain fabric 250, the transmission connection assembly 270 can effectively disperse the tension of the transmission member, avoid the deformation or tearing of the curtain fabric 250 caused by local stress concentration, and at the same time, the sliding design in the guide rail 240 ensures that the curtain fabric 250 always maintains a straight motion trajectory during the expansion and winding process, avoiding the problems of curtain fabric 250 deviation, jamming and other problems, significantly improving the stability and reliability of the device operation, and bringing users a smoother use experience.

[0084] Please continue to refer to Figure 13 In some embodiments, the transmission connection assembly 270 includes a sliding block 271 and a connecting block 272, wherein one end of the sliding block 271 is connected with one end of the corresponding transmission assembly, the other end is connected with one end of the connecting block 272, the other end of the connecting block 272 is connected with the curtain fabric 250, and the sliding block 271 and the connecting block 272 are connected and arranged in the guide rail 240.

[0085] One end of the sliding block 271 is firmly connected with the end of the transmission member, ensuring that the tension of the transmission member can be stably transmitted; the other end is connected with the front end of the connecting block 272. The connecting block 272 is fixed with the edge of the curtain fabric 250 by welding, riveting or clamping and the like. After the sliding block 271 and the connecting block 272 are connected in cooperation, they are embedded in the sliding groove of the guide rail 240, so that the entire transmission connection assembly 270 can realize smooth sliding in the guide rail 240.

[0086] Therefore, through the split design of the sliding block 271 and the connecting block 272, damaged parts can be quickly disassembled and replaced during maintenance, reducing maintenance costs; at the same time, the cooperation structure of the sliding block 271 and the sliding groove of the guide rail 240 effectively limits the movement trajectory of the assembly, preventing the curtain fabric from running off, jamming and the like, thereby improving the stability and reliability of the operation of the sunshade curtain system, prolonging the service life of the curtain fabric and protecting the user's experience.

[0087] Please continue to refer to Figure 3 In some embodiments, the first frame curtain assembly and the second frame curtain assembly each include two guide rails 240, and the two guide rails 240 are respectively arranged at the two ends of the first cross beam 120 and the corresponding second cross beam 210, and form a U-shaped structure with the second cross beam 210.

[0088] Among them, the guide rail 240 is provided with a sliding groove for accommodating the transmission connection assembly 270, and the shape and size of the sliding groove are accurately designed to ensure that the transmission connection assembly 270 can smoothly slide therein. The second cross beam 210 serves as the bottom of the U-shaped structure, providing a stable mounting base for components such as the reel 220, the first fixed seat 231 and the second fixed seat 232. The guide rail 240 and the second cross beam 210 are fixed by welding, riveting or high-strength bolts, forming a solid overall frame.

[0089] In some embodiments, the sliding block 271 can be provided with a first clamping portion, and the connecting block 272 is provided with a second clamping portion. When the first clamping portion and the second clamping portion are clamped, the sliding block 271 and the connecting block 272 are fixedly connected.

[0090] Therefore, when the sliding block 271 and the connecting block 272 are assembled, the first clamping portion is pushed along the guide groove of the second clamping portion, and the assembly and disassembly can be quickly completed without the need for additional tools, improving the assembly efficiency; and through the clamping of the first clamping portion and the second clamping portion, the stable transmission of the transmission member and the curtain fabric 250 can be ensured.

[0091] Please refer to Figure 14 , Figure 14A schematic view of the structure of the curtain fabric in some embodiments of the present application. In some embodiments, the curtain fabric 250 comprises a curtain fabric body 251, a pull rod 252 and a side strip 253, wherein the pull rod 252 is arranged at the free end of the curtain fabric body 251 and fixedly connected with the curtain fabric 250, and the side strip 253 is arranged at both ends of the curtain fabric body 251 and used to form a stable support structure during the operation of the curtain fabric 250. Specifically, the side strip 253 can be precisely embedded in the clamping jaw of the guide rail 240, limiting the lateral deviation of the curtain fabric body 251 through cooperation with the guide rail 240, and continuously providing longitudinal tension when the curtain fabric 250 is unfolded or rolled up, ensuring that the curtain fabric body 251 always remains in a flat and tensioned state, avoiding wrinkles, jamming or poor operation caused by relaxation, and significantly improving the stability of the curtain fabric operation and the reliability of the sunshade effect.

[0092] Wherein the curtain fabric body 251 can be made of high-strength and weather-resistant materials to ensure that it is not easily deformed or faded during long-term use; the pull rod 252 can be made of lightweight aluminum alloy or iron material and is firmly fixed at the free end of the curtain fabric body 251 through precise riveting or bonding, thereby enhancing the rigidity of the end of the curtain fabric 250 and keeping it flat when unfolded, and providing a stable stress point for the curtain fabric 250.

[0093] Therefore, the structural arrangement of the curtain fabric 250 improves the overall structural strength and wind resistance of the curtain fabric 250, effectively preventing the curtain fabric 250 from shaking or shifting even during high-speed driving of the vehicle, providing users with a more reliable and comfortable user experience, and prolonging the service life of the curtain fabric.

[0094] The driving principle of the curtain fabric 250 of the sunshade curtain assembly 100 of the present application is as follows: when the driving mechanism (motor) is started by controlling the switch, the rotation of the output shaft of the motor drives the first transmission assembly 145 and the second transmission assembly 146 connected thereto to move along the trajectories of the first set of through channels 147 and the second set of through channels 148, and the movement of the first transmission assembly 145 and the second transmission assembly 146 is transmitted to the curtain fabric 250 through the transmission connection assembly 270, specifically: the pulling force of the first transmission assembly 145 and the second transmission assembly 146 acts on the sliding block 271, the sliding block 271 slides along the guide rail 240, and the first clamping part and the second clamping part cooperate to drive the connecting block 272 to move synchronously, the connecting block 272 in turn pulls the curtain fabric body 251 connected thereto, realizing the unfolding of the curtain fabric 250. When the motor reverses, the first transmission assembly 145 and the second transmission assembly 146 move in the opposite direction, and the elastic element in the winding shaft 220 releases the pre-tightening force, assisting the winding shaft 220 to wind and recover the curtain fabric 250.

[0095] During operation, the pull rod 252 ensures that the free end of the curtain fabric 250 remains flat, and the cooperation of the side strip 253 and the guide rail 240 ensures the stability of the movement trajectory of the curtain fabric 250.

[0096] Thus, through the cooperation of the driving mechanism and the pre-tightening force of the elastic element, not only the automatic control of the curtain 250 deployment and winding is realized, but also the load of the driving mechanism is reduced, the energy consumption is reduced, and the service life of the driving mechanism is prolonged. In addition, through the design of the transmission connection assembly 270 and the guiding effect of the guide rail 240, the efficiency and stability of power transmission are ensured, and the jamming and noise during operation are reduced. At the same time, the structure of the curtain body 251 is reinforced by the pull rod 252 and the side strip 253, which improves the anti-deformation ability and durability of the sunshade curtain as a whole. Even in frequent use or complex environment, it can still maintain a stable and reliable working state, providing users with long-term high-quality use experience.

[0097] In some embodiments, the locking method of the guide rail 240 and the first and second fixed seats 231 and 232 can be that the guide rail 240 is provided with a first mounting slot and a second mounting slot extending along its extension direction, the first fixed seat 231 is provided with a first clamping slot matched with the first mounting slot, and the second fixed seat 232 is provided with a second clamping slot matched with the second mounting slot. When the first clamping slot is embedded in the first mounting slot and the second clamping slot is embedded in the second mounting slot, at least part of the first and second fixed seats 231 and 232 is clamped with the guide rail 240.

[0098] During installation, the first clamping slot of the first fixed seat 231 is aligned with the first mounting slot of the guide rail 240, and the second clamping slot of the second fixed seat 232 is aligned with the second mounting slot. By pressing, the clamping slot and the mounting slot are embedded with each other.

[0099] Thus, through the precise matching of the clamping slot and the mounting slot, the first fixed seat 231, the second fixed seat 232 and the guide rail 240 are quickly installed and disassembled, which greatly improves the assembly efficiency, reduces the labor cost, and forms a stable mechanical connection between the first fixed seat 231 and the second fixed seat 232 and the guide rail 240. It effectively resists the vibration and external impact during vehicle driving, ensures that the sunshade curtain assembly remains stable during long-term use, and reduces the abnormal noise and failure caused by loose parts.

[0100] Please continue to refer to Figure 1 In some embodiments, the first cross beam 120 is arranged between the first panel area 101 and the second panel area 102, and the first frame curtain assembly 201 and the second frame curtain assembly 202 are arranged along the width direction of the first cross beam 120.

[0101] Thus, the first frame curtain assembly 201 and the second frame curtain assembly 202 are arranged along the width direction of the first cross beam 120, which can reasonably distribute the two sunshade curtain assemblies in the limited roof space, avoid space waste caused by structural overlap, make the roof layout more compact and orderly, and enable the first drive mechanism 131 and the second drive mechanism 132 to drive the corresponding transmission members to drive the corresponding curtain fabrics to move, respectively.

[0102] Alternatively, refer to Figure 15 , Figure 15 Another structural schematic diagram of the sunshade curtain assembly in some embodiments of the present application is shown. In some embodiments, the first cross beam 120 is arranged at one end of the first panel area 101 away from the second panel area 102, or the first cross beam 120 is arranged at one end of the second panel area 102 away from the first panel area 101.

[0103] Please refer to Figure 16 , Figure 16 is a structural schematic diagram of the middle cross beam in Figure 15 . Thus, when the first cross beam 120 is arranged at one end of the first panel area 101 away from the second panel area 102 or the first cross beam 120 is arranged at one end of the second panel area 102 away from the first panel area 101, the sunshade curtain assembly 100 further comprises a middle cross beam 180, and the middle cross beam 180 is provided with the first frame curtain assembly 201 and the second frame curtain assembly 202.

[0104] Thus, by arranging the middle cross beam 180 in the sunshade curtain assembly 100 and integrating the first frame curtain assembly 201 and the second frame curtain assembly 202 on the middle cross beam 180, the middle cross beam 180 provides a stable and unified support carrier for the first frame curtain assembly 201 and the second frame curtain assembly 202, improves the structural strength and installation precision of the sunshade curtain system, ensures the smoothness of the rotation of the curtain fabric, and makes the curtain fabric more stable during the unwinding and winding operations; and optimizes the space occupation, facilitating the cooperation of various components.

[0105] Please refer to Figure 17 , Figure 17 is another structural schematic diagram of the vehicle in some embodiments of the present application. In some embodiments, the first cross beam 120 includes two first cross beams 120, which are arranged at one end of the first panel area 101 away from the second panel area 102 and at one end of the second panel area 102 away from the first panel area 101, respectively.

[0106] Wherein, the two first cross beams 120 are respectively arranged at one end of the first panel area 101 away from the second panel area 102 and one end of the second panel area 102 away from the first panel area 101, which can form independent and targeted edge support and structural reinforcement for different panel areas, effectively dispersing external forces on each panel area, improving the structural stability of the first panel area 101 and the second panel area 102 respectively, avoiding deformation of the transparent panel or the periphery injection molding structure caused by unilateral stress concentration, and prolonging the service life of the overall structure.

[0107] Thus, the first driving mechanism 131 and the second driving mechanism 132 are respectively arranged in the two first cross beams to drive the curtain fabric 250 of the first frame curtain fabric assembly 201 and the second frame curtain fabric assembly 202 to move respectively.

[0108] Thus, the position and number of the first cross beams 120 can be set according to actual conditions, and the driving of the first transmission assembly 145 and the second transmission assembly 146 can be achieved, which can be installed at different positions of the vehicle according to the design requirements of different vehicle models, thereby adapting to various vehicle structures.

[0109] Please refer to Figure 18 , Figure 18 is a structural diagram of a vehicle in some embodiments of the present application. In some embodiments, the vehicle 300 includes a vehicle body 310 and a sunshade curtain assembly 100 as in any of the preceding embodiments, and the sunshade curtain assembly 100 is connected to the vehicle body 310.

[0110] Thus, by connecting the sunshade curtain assembly 100 to the vehicle body 310, the vehicle 300 fully utilizes the advantages of the sunshade curtain assembly 100, such as independent control of different areas, compact structure, stable transmission, etc.: it meets the individual sunshade needs of different areas in the vehicle, improving the driving comfort; and thanks to its precise positioning structure, it ensures the installation compatibility with the vehicle body 310, reduces the risk of assembly interference, and at the same time, the compact internal layout adapts to the limited space of the vehicle, improving the functional practicability and structural reliability of the vehicle 300 as a whole.

[0111] Please refer to Figure 19 , Figure 19 is a flowchart of a processing and assembling method of a sunshade curtain assembly in some embodiments of the present application. In some embodiments, the processing and assembling method of the sunshade curtain assembly includes the following steps: Step S10: embedding a first group of through channels and a second group of through channels in the mold cavity; Step S20: injecting a molten plastic solution into the mold cavity to integrally form the transparent panel and the first cross beam, the transparent panel including a first panel area and a second panel area, and the first cross beam being provided with a first mounting groove and a second mounting groove; Step S30: Install the first drive mechanism in the first mounting slot and install the second drive mechanism in the second mounting slot; Step S40: Install the first frame curtain assembly corresponding to the first panel area, and make the first transmission component pass through the first set of passing channels. One end of the first transmission component is connected to the curtain of the first frame curtain assembly. The first drive mechanism is used to drive the first transmission component to drive the curtain to move. Step S50: Install the second frame curtain assembly on the second panel area, and make the second transmission component pass through the second set of passing channels. One end of the second transmission component is connected to the curtain of the second frame curtain assembly. The second drive mechanism is used to drive the second transmission component to move the curtain.

[0112] In step S10, after pre-embedding the first and second sets of through-channels, step S20 injects molten plastic to integrally mold the transparent panel and the first crossbeam, forming a robust integrated structure between the through-channels, crossbeam, and panel. This reduces gaps and loosening risks in component connections during traditional assembly, while ensuring the positional accuracy of the through-channels, laying the foundation for smooth operation of subsequent transmission components. Step S30 installs the drive mechanism in the pre-set mounting slot, ensuring the drive position matches the through-channels. Steps S40 and S50 install the curtain assembly in the corresponding panel area and connect the transmission components, ensuring precise alignment of the transmission path with the drive mechanism and through-channels, reducing functional interference caused by assembly deviations. The overall process has a clear division of labor and close coordination, improving assembly efficiency and ensuring the long-term stable operation of the sunshade assembly through structural integration and precise alignment.
