Description

Technical Field

[0001] This application relates to automotive parts, and more particularly to a sunshade assembly, a vehicle, and a processing and assembly method. Background Technology

[0002] In the automotive interior design field, the sunshade assembly is a key component for improving driving and riding comfort. Its structural design and performance directly affect the light-blocking effect, space layout, and assembly efficiency inside the vehicle. Traditional sunshade solutions use a step-by-step locking method, where the front crossbeam is treated as an independent component and locked separately with other components to form the sunshade assembly, which is then fixed with multiple bolts. This results in a bulky overall structure, cumbersome assembly procedures, and gaps in the fit of the separate structure, making it difficult to adapt to the development trend of lightweight and modular assembly in automobiles. Summary of the Invention

[0003] The purpose of this application is to provide a sunshade assembly, a vehicle, and a processing and assembly method to solve the problems mentioned in the background art.

[0004] To address the aforementioned problems, in a first aspect, a sunshade assembly is provided, comprising: a transparent panel, the transparent panel including a first panel area and a second panel area; a first crossbeam, the first crossbeam being integrally formed with the transparent panel; the first crossbeam having a first driving mechanism, a second driving mechanism, a first set of through channels, and a second set of through channels; a first frame curtain assembly, corresponding to the first panel area; a first transmission component, the first transmission component passing through the first set of through channels, one end of the first transmission component being connected to the curtain of the first frame curtain assembly, the first driving mechanism driving the curtain of the first frame curtain assembly to unfold and cover the first panel area via the first transmission component; a second frame curtain assembly, corresponding to the second panel area; a second transmission component, the second transmission component passing through the second set of through channels, one end of the second transmission component being connected to the curtain of the second frame curtain assembly, the second driving mechanism driving the curtain of the second frame curtain assembly to unfold and cover the second panel area via the second transmission component.

[0005] Therefore, this sunshade assembly integrates the first crossbeam and the transparent panel into one piece. Within the first crossbeam, a first drive mechanism, a second drive mechanism, and a first set of through-channels corresponding to the first and second panel areas are integrated. A first frame curtain assembly, a second frame curtain assembly, and corresponding first and second transmission components are also provided. This eliminates the assembly steps and connecting parts between the crossbeam and the transparent panel in traditional split designs, reducing space occupation and making the sunshade assembly more suitable for the compact layout of vehicle interiors. Furthermore, the corresponding configuration of the dual drive mechanism, dual through-channels, transmission components, and frame curtain assembly allows the curtains in the first and second panel areas to be independently unfolded or rolled up, meeting users' needs for sun shading in different areas and improving usability.

[0011] In one possible embodiment of the first aspect, the sunshade assembly further includes two third crossbeams, which are disposed opposite to the first crossbeam and respectively located in the first panel area and the second panel area. Both third crossbeams are integrally formed with the transparent panel. In one possible embodiment of the first aspect, one side of each of the two third crossbeams is provided with an adhesive surface for bonding to the roof.

[0012] In one possible embodiment of the first aspect, the placement of the first driving mechanism and the second driving mechanism is adapted to the orientation of the through-channel in the first crossbeam.

The second driving mechanism is located beside the extension path of the second set of through-channels, and its output end is connected to the second transmission component.

[0013] In one possible embodiment of the first aspect, the first driving mechanism is disposed on one side of the extension path of the first set of through channels, and the second driving mechanism is disposed on the other side of the extension path of the second set of through channels, wherein the first driving mechanism and the second driving mechanism are respectively located on opposite sides of the first set of through channels and the second set of through channels.

[0014] In one possible embodiment of the first aspect, the sunshade assembly further includes an end positioning member, which is disposed within the first crossbeam and corresponds to the ends of the first set of through channels and the second set of through channels, and is integrally disposed with the transparent panel. The ends of the two hollow tubular structures of the first set of through channels and the two hollow tubular structures of the second set of through channels are respectively connected to the end positioning member.

[0015] In one possible embodiment of the first aspect, the end positioning member further includes a positioning structure for limiting the end positioning member when the end positioning member is integrally disposed with the transparent panel.

[0016] In one possible embodiment of the first aspect, the first set of through channels includes a first through channel and a second through channel, the first through channel serving as a power pipe for moving the first transmission component when the curtain is unfolded, and the second through channel serving as a retrieval pipe for retrieving and guiding the first transmission component back to its original position; the second set of through channels includes a third through channel and a fourth through channel, the third through channel serving as a power pipe for moving the second transmission component when the curtain is unfolded, and the fourth through channel serving as a retrieval pipe for retrieving and guiding the second transmission component back to its original position.

[0017] In one possible embodiment of the first aspect, the sunshade assembly further includes a positioning element integrally disposed with the transparent panel and protruding from the surface of the transparent panel for installation positioning when the sunshade assembly is installed with the vehicle body.

[0018] In one possible embodiment of the first aspect, the first crossbeam is disposed between the first panel area and the second panel area, and the first frame curtain assembly and the second frame curtain assembly are spaced apart along the width direction of the first crossbeam; or the first crossbeam is disposed at one end of the first panel area away from the second panel area, or the first crossbeam is disposed at one end of the second panel area away from the first panel area.

[0019] In one possible embodiment of the first aspect, the first crossbeam includes two beams, which are respectively disposed at one end of the first panel area away from the second panel area and at one end of the second panel area away from the first panel area, and the first drive mechanism and the second drive mechanism are respectively disposed on the two first crossbeams.

[0020] In a second aspect, a vehicle is provided, including a body and a sunshade assembly as described in the first aspect, the sunshade assembly being connected to the body.

[0021] Thirdly, a method for processing and assembling a sunshade assembly is provided, comprising: pre-embedding at least a first set of through channels and a second set of through channels in a mold cavity; injecting molten plastic solution into the mold cavity to integrally form the transparent panel and the first crossbeam, the transparent panel including a first panel area and a second panel area, the first crossbeam being provided with a first mounting groove and a second mounting groove; installing a first driving mechanism in the first mounting groove and installing a second driving mechanism in the second mounting groove; installing a first frame curtain assembly corresponding to the first panel area, and such that a first transmission component passes through the first through channel, one end of the first transmission component being connected to the curtain of the first frame curtain assembly, the first driving mechanism being used to drive the first transmission component to move the curtain; installing a second frame curtain assembly in the second panel area, and such that a second transmission component passes through the second through channel, one end of the second transmission component being connected to the curtain of the second frame curtain assembly, the second driving mechanism being used to drive the second transmission component to move the curtain.

[0022] Therefore, the integrated structure of the first crossbeam and the transparent panel 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, and is more suitable for the limited installation space inside the vehicle. By pre-embedding the corresponding through-channels before the injection molding of the first crossbeam, its position and direction can be precisely controlled, effectively avoiding the above-mentioned demolding process limitations, and eliminating the need to consider the impact of the demolding slope on the channel structure and dimensional accuracy. The integration of the dual drive mechanism and the corresponding through-channels solves the problem of redundant connecting parts and assembly processes in traditional split structures. The dual through-channels adopt a stacked hollow tubular structure, which, together with the precise limiting of the end positioning parts, ensures that the transmission components do not interfere with each other, reduces the risk of jamming and other failures, and improves the long-term reliability of the sunshade assembly.

[0023] The independent configuration of the dual-drive mechanism and the dual-frame curtain assembly enables complete separation control of the sunshade functions of the first and second panel areas. Users can flexibly adjust the unfolding state of the curtains in each area according to the actual scenario, which greatly enhances the flexibility and personalized experience compared to the traditional single curtain solution. The integrated design of the insert structure and positioning components simplifies the installation process of the sunshade assembly and the vehicle body. The integrated drive mechanism and through-channel, with its layered hollow tubular through-channel, significantly reduces the vertical space occupation, adapting to the limited space of the vehicle. The bonding surface of the third crossbeam enables a convenient and stable connection with the roof.

[0024] For vehicles, the installation of this sunshade assembly can optimize the comfort of the in-vehicle ride through independent zoned sunshade. The integrated processing and assembly method, through pre-embedded channels and one-piece injection molding, reduces the number of parts and assembly steps, ensures precise positioning of components, improves structural strength and sealing, reduces locking steps, improves efficiency, and facilitates later maintenance and replacement.

[0029] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0030] Please see 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 a first frame curtain assembly 201 and a second frame curtain assembly 202. These are driven and controlled by independent first drive mechanisms 131 and 145, and second drive mechanisms 132 and 146, respectively. This design allows users to individually adjust the unfolding or retracting state of the curtain 250 according to the light intensity of different areas and usage scenarios (such as different needs of front and rear passengers), fully meeting diverse sunshade needs.

[0033] The first transmission component 145 and the second transmission component 146 are respectively inserted into the first set of insertion channels 147 and the second set of insertion channels 148. The insertion channels effectively protect and limit the transmission components, reducing wear or jamming caused by shaking and friction during transmission. At the same time, the corresponding connection between the drive mechanism and the transmission components ensures direct and stable power transmission, reduces transmission loss, and improves the smoothness of the curtain 250 unfolding / retracting. In the actual connection where the first transmission component 145 is inserted into the first set of insertion channels 147 and the second transmission component 146 is inserted into the second set of insertion channels 148, the ends of the two sets of transmission components near the corresponding drive mechanisms are precisely meshed with the output shafts of the first drive mechanism 131 and the second drive mechanism 132 respectively through intermediate gears. This gear transmission connection method provides directness and stability for both sets of power transmission. The intermediate gear, as a transmission bridge, can match the rotational speeds of the first transmission component 145 and the output shaft of the first drive mechanism 131, and the second transmission component 146 and the output shaft of the second drive mechanism 132, respectively, to achieve efficient transmission of the two sets of power and reduce energy loss.

[0034] In addition, the two sets of frame curtain assemblies, transmission components and drive mechanisms adopt a modular design, with each component functioning independently. This facilitates standardized production to reduce costs, enables independent maintenance of individual components during later maintenance, and allows for flexible expansion according to the panel area division requirements, thus possessing strong adaptability.

[0035] Please see Figure 4 , Figure 4This is another structural schematic diagram of the sunshade assembly in some embodiments of this application. The first crossbeam 120 and the transparent panel 110 are integrally configured as follows: when the transparent panel 110 is injection molded with PU (polyurethane), a cavity for the first crossbeam 120 is added to the original mold. While the molten PU material wraps the outer edge and other structures of the transparent panel 110, the PU material is integrally formed into the main structure of the first crossbeam 120 in the cavity corresponding to the first crossbeam 120 using the pre-set cavity in the mold. The PU material of the first crossbeam 120 is naturally connected to the PU layer wrapping the edge of the transparent panel 110 as a whole, realizing the integral configuration of the first crossbeam 120 and the transparent panel 110 through the same PU injection molding process.

[0036] In some embodiments, when the first crossbeam 120 and the transparent panel 110 are integrally formed, materials such as polyvinyl chloride (PVC), thermoplastic elastomer (TPE), or ethylene propylene diene monomer (EPDM) can also be used, achieving structural integration through precise mold cavity design. During injection molding, molten PVC, with its good fluidity, can tightly wrap the edges of the transparent panel 110 and fill the cavity of the first crossbeam 120, forming an integral structure with rigidity and toughness. TPE material, with its thermoplastic properties, maintains the required structural strength of the first crossbeam 120 after injection molding, while also possessing a certain degree of aging resistance, reducing the risk of cracking during long-term use. EPDM material, through a high-temperature vulcanization injection molding process, can form stable chemical bonds at the junction with the edges of the transparent panel 110, significantly improving the overall structural sealing and making it suitable for outdoor use scenarios such as vehicles. The injection molding material may be selected from one or more of them according to actual needs and application scenarios, and no specific limitation is made here.

[0037] Please refer to the following: Figure 5 , Figure 5 This is a structural diagram of an existing sunshade assembly. (Example:) Figure 5 As shown, after the existing first crossbeam and transparent panel are installed, there will be a gap of at least 6mm between the first crossbeam and the transparent panel, and if... Figure 4 As shown, the first crossbeam 120 and the transparent panel 110 are integrally set, thereby achieving zero gap between the first crossbeam 120 and the transparent panel 110, thus reducing the space occupied in the direction perpendicular to the first crossbeam 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 reading. Figure 6 In some embodiments, the sunshade assembly 100 further includes at least one positioning member 190, which is integrally disposed with the transparent panel 110 and protrudes from the surface of the transparent panel 110 for installation positioning when the sunshade assembly 100 is installed with the vehicle body.

[0044] Thus, during the assembly process, the positioning component 190 can quickly align and cooperate with the preset installation position on the vehicle body, reducing the time spent on position adjustment during the installation process, ensuring that the sunshade assembly 100 can be accurately fixed to the vehicle body in the designed posture, avoiding functional interference caused by installation deviation (such as obstruction of curtain unfolding), etc. At the same time, the integrated structure strengthens the connection strength of the positioning component 190, ensuring positioning stability during long-term use, and improving the overall assembly efficiency and reliability.

[0045] Please continue reading. Figure 2 In some embodiments, the first set of through channels 147 includes a hollow tubular structure that extends along the length of the first crossbeam 120 and is used to pass through the first transmission assembly 145 and provide a guide path to the first transmission assembly 145; the second set of through channels 148 includes a hollow tubular structure that extends along the length of the first crossbeam 120 and is used to pass through the second transmission assembly 146 and provide a guide path to the second transmission assembly 146.

[0046] Therefore, the hollow tubular structure can provide a stable and precise guiding path for the first transmission component 145 and the second transmission component 146, effectively avoiding friction or interference between the first transmission component 145 and the second transmission component 146 and other components inside the first crossbeam 120, reducing wear and extending service life; at the same time, its through-layout along the length of the first crossbeam 120 makes the routing of the first transmission component 145 and the second transmission component 146 more regular, which helps to improve the transmission efficiency of the first drive mechanism 131 and the second drive mechanism 132 to the first transmission component 145 and the second transmission component 146 respectively, ensuring a smooth and stable unfolding or winding process of the curtain 250, and improving the user experience.

[0047] In some embodiments, the hollow tubular structure is a flexible hose. By using a flexible hose as the insertion channel, its good flexibility allows for a closer fit to the inner wall of the first crossbeam 120 during injection molding, effectively avoiding installation compatibility issues caused by structural complexity. Simultaneously, the hose material can buffer vibrations and friction generated during the movement of the transmission components, reducing surface wear and extending their service life. Furthermore, the elasticity of the hose structure can absorb noise generated by the movement of the transmission components to a certain extent, making the curtain drive system operate more quietly and smoothly, significantly improving the user experience.

[0048] Please refer to the following: Figure 7 , Figure 7 for Figure 2 The schematic cross-sectional view of the through-channels shown indicates that, in some embodiments, the first set of through-channels 147 includes at least two hollow tubular structures, and at least a portion of the two hollow tubular structures are stacked on a plane perpendicular to the first crossbeam 120, for passing through different transmission components of the first transmission assembly 145 respectively; the second set of through-channels 148 includes at least two hollow tubular structures, and at least a portion of the two hollow tubular structures are stacked on a plane perpendicular to the first crossbeam 120, for passing through different transmission components of the second transmission assembly 146 respectively.

[0049] Among them, at least two hollow tubular structures in the first set of through channels 147 and at least two hollow tubular structures in the second set of through channels 148 are arranged in a "stacked arrangement perpendicular to the plane where the first crossbeam 120 is located". This achieves independent installation of multiple transmission components through longitudinal layering, avoiding space encroachment or interference caused by lateral parallel arrangement between different transmission components of the first transmission assembly 145 and different transmission components of the second transmission assembly 146, and significantly improving the utilization rate of the internal space of the crossbeam.

[0050] Meanwhile, the layered, independent hollow tubular structure provides dedicated guide paths for each transmission component, ensuring that the first transmission assembly 145 and the second transmission assembly 146 do not interfere with each other during movement. This effectively reduces the risk of friction and entanglement between transmission components, ensuring the smoothness and stability of the transmission process. Furthermore, this layered layout avoids the extra space required for multiple transmission components to be laid side-by-side along the vehicle's length, reducing space occupation in that direction and freeing up more space for the arrangement of other roof components. This facilitates a more compact, modular design for the vehicle roof. The vehicle's length direction is perpendicular to the hollow tubular structure located within the first crossbeam 120.

[0051] In some embodiments, please continue reading Figure 2The first set of through channels 147 has two hollow tubular structures, each divided into two parts, located on both sides of the first drive mechanism 131; the second set of through channels 148 has two hollow tubular structures, each divided into two parts, located on both sides of the second drive mechanism 132, to avoid the first drive mechanism 131 and the second drive mechanism 132.

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

[0053] Therefore, in terms of actual quantity, the first set of through channels 147 actually includes four independent hollow tubular structures. These four tubular structures are distributed on both sides of the first drive mechanism 131, with two located on one side of the first drive mechanism 131 and the other two located on the other side of the first drive mechanism 131. This arrangement achieves avoidance of the first drive mechanism 131. Similarly, the second set of through channels 148 also includes four independent hollow tubular structures, which are placed on both sides of the second drive mechanism 132.

[0054] The core advantage of this structural design lies in maximizing space utilization: the four tubular structures of the first set of through channels 147 are distributed around the first drive mechanism 131, cleverly avoiding the installation space of the drive mechanism in the first crossbeam 120. This not only avoids layout conflicts between components, but also enables the independent accommodation of multiple transmission components within the limited crossbeam, providing dedicated through paths for different transmission components of the first transmission assembly 145.

[0055] Meanwhile, the four independent hollow tubular structures ensure the stability and reliability of the transmission process: each transmission component can extend independently through the tubular structure on the corresponding side, and the transmission path from the output end of the corresponding drive mechanism to the curtain 250 remains continuous, reducing transmission losses caused by path intersections or bends; and the closed tubular structure can effectively isolate different transmission components, avoiding friction, entanglement or jamming problems during movement.

[0056] Please see Figure 8 , Figure 8 This is a schematic diagram of the structure of the transparent panel in some embodiments of this application. In some embodiments, the sunshade assembly 100 further includes an insert structure 170, which is integrally disposed with the transparent panel 110, wherein the insert structure 170 includes at least a nut.

[0057] During injection molding, the insert structure 170 is pre-positioned in the corresponding position in the mold. When injection molding materials such as PU, polyvinyl chloride (PVC), thermoplastic elastomer (TPE), or ethylene propylene diene monomer (EPDM) are injected to wrap around the edge of the transparent panel 110, the insert structure 170 is simultaneously embedded into the PU layer. This allows the nut and the transparent panel 110 to form an inseparable integral structure through PU injection molding. 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 PU structure. Thus, by injection molding the insert structure 170, damage to the transparent panel or PU structure during subsequent processing is avoided, ensuring connection strength and reducing the need for separate bolt assembly.

[0058] In some embodiments, the drive mechanism is a motor, and the output shaft of the motor is connected to a corresponding transmission component to drive the curtain 250 to unfold or be wound onto a roller.

[0059] During operation, the motor outputs forward or reverse power according to control commands, and drives the transmission components through the output shaft to perform the winding and unwinding movements, thereby causing the curtain to smoothly unfold along the guide rail or tightly wind onto the roller. It features rapid response and low operating noise, improving the automation level and user experience of the sunshade system.

[0060] The drive mechanism can also be a pneumatic drive component, which uses the linear power output by the cylinder to convert it into the traction power of the transmission component, thereby driving the curtain to move; the drive mechanism can also include a hydraulic drive component, which uses the extension and retraction of the hydraulic cylinder to drive the transmission component, and is suitable for scenarios with large driving force requirements.

[0061] In some embodiments, please refer to the following: Figure 1 and Figure 2 The placement of the first drive mechanism 131 and the second drive mechanism 132 is adapted to the orientation of the through-channel in the first crossbeam 120. The first drive mechanism 131 is located beside the extension path of the first set of through-channels 147, and its output end is connected to the first transmission component 145. The second drive mechanism 132 is located beside the extension path of the second set of through-channels 148, and its output end is connected to the second transmission component 146.

[0062] The first drive mechanism 131 and the second drive mechanism 132 are adapted to the direction of the corresponding through-channel and are located on the side of the extension path. This ensures that the output end of the drive mechanism is accurately connected to the first transmission component 145 and the second transmission component 146. The drive mechanism is arranged along the extension direction of the channel so that the corresponding transmission component can be directly connected to the corresponding drive mechanism after passing through the corresponding through-channel. This shortens the power transmission path and reduces the risk of bending or deviation during the transmission process. At the same time, the side-mounted position allows the drive mechanism and the through-channel to form a tight fit within the first crossbeam 120. This avoids layout interference between components and ensures the smooth movement of the transmission components, further improving the stability of the power transmission and the structural integration of the sunshade assembly 100.

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

[0064] The first drive mechanism 131 and the second drive mechanism 132 are arranged in a reverse staggered layout: the first drive mechanism 131 is located on one side of the extension path of the first set of through channels 147 (e.g., the left side), while the second drive mechanism 132 is located on the opposite side of the extension path of the second set of through channels 148 (e.g., the right side), so that the two are located on opposite sides of the two sets of through channels, forming a spatial distribution relationship where they do not approach each other. This layout avoids the concentrated arrangement of the two sets of drive mechanisms within the first crossbeam 120 by clearly defining the lateral position of the drive mechanism relative to the corresponding channel.

[0065] Thus, this layout design reduces the risk of spatial interference between the first drive mechanism 131 and the second drive mechanism 132, reserves independent installation space for the two drive mechanisms within the limited crossbeam, reduces structural bulkiness caused by component stacking, improves space utilization, and further ensures the stability and smoothness of the operation of the sunshade assembly 100.

[0066] Please continue reading. Figure 2 In some embodiments, the sunshade assembly 100 further includes an end positioning member 149, which is disposed within the first crossbeam 120 and corresponds to the ends of the two sets of through channels, and is integrally disposed with the transparent panel 110. The ends of the two hollow tubular structures of the first set of through channels 147 and the two hollow tubular structures of the second set of through channels 148 are respectively connected to the end positioning member 149.

[0067] The end positioning component 149 is arranged at the ends of the two sets of through channels and is connected to the hollow tubular structure ends of the first set of through channels 147 and the second set of through channels 148 respectively. It can accurately position and fix the ends of each tubular structure, avoid displacement or loosening of the channel due to the movement of the transmission component or external vibration during long-term use, ensure that the extension path of the through channel always remains stable, and provide reliable guidance for the transmission component.

[0068] Meanwhile, the end positioning component 149 and the transparent panel 110 are integrated, which further strengthens the integrity of the internal structure of the first crossbeam 120. The end positioning component 149 forms a rigid connection between the through channel and the transparent panel 110, reducing the assembly gap and relative sway between components, and improving the structural sealing and firmness of the sunshade assembly 100.

[0069] In some embodiments, the end positioning member 149, the first set of through channels 147, and the second set of through channels 148 can be integrated into a single design, i.e., they are the same component. Specifically, the hollow tubular structures of the end positioning member 149 and each set of through channels are manufactured through the same molding process, forming an integral structure. This eliminates the connection gap between the end positioning member 149 and the through channels, allowing them to deform synchronously and bear loads collaboratively under stress, further improving the guiding stability of the transmission components, while reducing assembly errors and significantly enhancing the rigidity and durability of the overall structure.

[0070] Furthermore, the end positioning component 149 is also provided with holes that communicate with the channels of each hollow tubular structure. These holes, together with the hollow portion of the through-channel, form a continuous channel structure, allowing the first transmission component 145 and the second transmission component 146 to smoothly extend from the through-channel into the holes of the end positioning component 149, achieving seamless connection of the transmission path. This avoids jamming or wear of the transmission components at the connection point between the through-channel and the end positioning component 149, ensuring stable operation along the preset path. It also provides a clearer guiding reference for the installation of the transmission components, improving assembly efficiency.

[0071] Please see Figure 9 , Figure 9 This is another structural schematic diagram of the through-channel in some embodiments of this application. In some embodiments, the end positioning member 149 further includes a positioning structure 1491, which is used to limit the end positioning member 149 when the end positioning member 149 is integrally disposed with the transparent panel 110.

[0072] During the integrated installation of the end positioning component 149 and the transparent panel 110, the positioning structure 1491 can effectively limit the installation position of the end positioning component 149, avoiding misalignment between the end of the component and the two sets of through channels due to assembly deviations. This ensures that the hollow tubular structure ends of the first set of through channels 147 and the second set of through channels 148 can be accurately connected to the end positioning component 149, providing a stable path guiding foundation for the transmission components.

[0073] Meanwhile, the positioning structure 1491 strengthens the relative position of the end positioning member 149 and the transparent panel 110, reducing the relative displacement caused by vibration, force and other factors during long-term use. This ensures the stability of the connection between the end of the passage and the end positioning member 149, and reduces the risk of friction and jamming caused by the displacement of the passage position when the transmission component moves.

[0074] Similarly, the corresponding mounting slots of the first drive mechanism 131 and the second drive mechanism 132 are also provided with drive mechanism positioning structures. During the process of assembling the first drive mechanism 131 and the second drive mechanism 132 into the first crossbeam 120, the drive mechanism positioning structures can effectively limit the installation position of the two, avoiding misalignment between the output end of the drive mechanism and the transmission component in the corresponding through-channel due to assembly deviation. This ensures that the power transmission interfaces of the first drive mechanism 131 and the first transmission component 145, and the second drive mechanism 132 and the second transmission component 146 are precisely aligned, providing a foundation for stable power output.

[0075] Please continue reading. Figure 9 In some embodiments, the first set of through channels 147 includes a first through channel 1471 and a second through channel 1472. The first through channel 1471 serves as a power pipe for moving the first transmission assembly 145 when the curtain is unfolded, and the second through channel 1472 serves as a retrieval pipe for retrieving and guiding the first transmission assembly 145 back to its original position. The second set of through channels 148 includes a third through channel 1481 and a fourth through channel 1482. The third through channel 1481 serves as a power pipe for moving the second transmission assembly 146 when the curtain is unfolded, and the fourth through channel 1482 serves as a retrieval pipe for guiding the second transmission assembly 146 back to its original position.

[0076] Please continue reading. Figure 3In some embodiments, the sunshade assembly 100 further includes a second crossbeam 210, a roller 220, a first fixing seat 231, a second fixing seat 232, a guide rail 240, and a curtain 250. The first fixing seat 231 and the second fixing seat 232 are respectively disposed at both ends of the roller 220 for connection to both ends of the roller 220. The guide rail 240 is disposed adjacent to the first fixing seat 231 or the second fixing seat 232 and is disposed opposite to both ends of the roller 220. The curtain 250 is wound around the roller 220. One end of the transmission member is connected to the curtain 250, and the other end is used to pass through the corresponding through-channel to connect with the output shaft of the corresponding drive mechanism.

[0077] The roller 220 is rotatably mounted on the first fixed seat 231 and the second fixed seat 232 to ensure smooth rotation and low resistance. The first fixed seat 231 and the second fixed seat 232 are respectively tightly fitted on both ends of the roller 220 to achieve stable support and limit of the roller. The curtain 250 is evenly and tightly wound on the roller 220. One end of the transmission component is firmly connected to the free end of the curtain 250, and the other end passes through the corresponding through-channel. The ends of the two sets of transmission components near the corresponding drive mechanisms are respectively meshed with the output shafts of the first drive mechanism 131 and the second drive mechanism 132 through the intermediate gear.

[0078] Therefore, the structural design of the sunshade assembly 100 of this application makes it convenient to install and disassemble each component, facilitating production assembly and subsequent maintenance. For example, when the curtain 250 is damaged, it can be quickly replaced by simply removing the first fixing seat 231 and the second fixing seat 232. Furthermore, the vertical layout of the guide rail 240 and the roller 220, combined with the transmission of the transmission components, enables the curtain 250 to unfold and roll up smoothly and efficiently, avoiding deviation or jamming during the operation of the curtain 250.

[0079] Please continue reading. Figure 9 In some embodiments, the first crossbeam 120 is provided with at least two fixing seat locking holes 141 for locking the first fixing seat 231 and the second fixing seat 232 respectively, wherein the fixing seat locking holes 141 are integrally injection molded with the first crossbeam 120.

[0080] In some embodiments, please refer to Figure 10 , Figure 10 This is a schematic diagram illustrating the installation of the reel and the mounting base in some embodiments of this application. One end of the reel 220 is provided with a core iron 222, and the other end is equipped with a rotating shaft 221. The two are securely connected by a high-precision concentric bushing. Please refer to [link to relevant documentation]. Figure 11 , Figure 11 for Figure 10 In the enlarged schematic diagram at point A, the rotating shaft 221 can rotate flexibly by engaging with the first fixed seat 231 via a wear-resistant bearing; please refer to... Figure 12, Figure 12 for Figure 10 In the enlarged schematic diagram at point B, the core iron 222 can be made of high-strength metal material and fits tightly with the second fixing seat 232 to ensure the stability of the reel during rotation.

[0081] The roller 220 contains an internal elastic element, which can be a helical spring or similar structure. One end of the elastic element is fixed to the core iron, and the other end is connected to the inner wall of the roller. When the curtain 250 is unrolled, the elastic element is stretched or twisted, causing deformation. When the drive mechanism stops driving the transmission components, the elastic element releases the preload, causing the roller 220 to automatically and smoothly wind up the curtain 250. Thus, the preload provided by the elastic element assists the drive mechanism, reduces the motor load, lowers energy consumption, and ensures that the curtain 250 maintains uniform tension during winding, preventing loosening and wrinkles, and extending the service life of the equipment.

[0082] Please see Figure 13 , Figure 13 for Figure 3 Enlarged schematic diagram at point C. In some embodiments, the sunshade assembly 100 further includes a transmission connection component 270, one end of which is connected to the first transmission component 145 and the second transmission component 146 and slidably disposed within the guide rail 240, and the other end of which is connected to the curtain fabric 250.

[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 smooth sliding of the curtain 250 along the guide rail direction. Compared with directly connecting the transmission component to the curtain 250, the transmission connection assembly 270 can effectively disperse the tension of the transmission component, avoiding localized stress concentration on the curtain 250 that could lead to deformation or tearing. At the same time, its sliding arrangement within the guide rail 240 ensures that the curtain 250 maintains a straight trajectory during unfolding and rewinding, avoiding problems such as curtain 250 deviation and jamming, significantly improving the stability and reliability of the device operation, and providing users with a smoother user experience.

[0084] Please continue reading. Figure 13 In some embodiments, the transmission connection assembly 270 includes a slider 271 and a connecting block 272, wherein one end of the slider 271 is connected to one end of the corresponding transmission assembly, and the other end is connected to one end of the connecting block 272, and the other end of the connecting block 272 is connected to the curtain 250. After the slider 271 and the connecting block 272 are connected together, they are disposed in the guide rail 240.

[0085] One end of the slider 271 is firmly connected to the end of the transmission component to ensure stable transmission of tension; the other end is connected to the front end of the connecting block 272. The connecting block 272 is fixed to the edge of the curtain 250 by welding, riveting, or snap-fitting. After the slider 271 and the connecting block 272 are connected, they are embedded in the groove of the guide rail 240, allowing the entire transmission connection assembly 270 to slide smoothly within the guide rail 240.

[0086] Therefore, the separate design of slider 271 and connecting block 272 facilitates quick disassembly and replacement of damaged parts during maintenance, reducing maintenance costs. At the same time, the matching structure of slider 271 and guide rail 240 effectively restricts the movement trajectory of the components, preventing the curtain from shifting or jamming during operation, thereby improving the stability and reliability of the sunshade system, extending the service life of the curtain, and ensuring the user experience.

[0087] Please continue reading. 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 disposed at both ends of the first crossbeam 120 and the corresponding second crossbeam 210, and together with the second crossbeam 210 form a U-shaped structure.

[0088] The guide rail 240 has a groove on its inner side to accommodate the transmission connection component 270. The shape and size of the groove are precisely designed to ensure that the transmission connection component 270 can slide smoothly in it. The second crossbeam 210 serves as the bottom of the U-shaped structure and provides a stable mounting base for components such as the roller 220, the first fixed seat 231, and the second fixed seat 232. The guide rail 240 and the second crossbeam 210 are fixed together by welding, riveting, or high-strength bolts to form a sturdy overall frame.

[0089] In some embodiments, the slider 271 may be provided with a first snap-fit ​​portion, and the connecting block 272 may be provided with a second snap-fit ​​portion. When the first snap-fit ​​portion and the second snap-fit ​​portion snap-fit ​​together, the slider 271 and the connecting block 272 are fixedly connected.

[0090] Therefore, when the slider 271 and the connecting block 272 are assembled, the first snap-fit ​​part is pushed in along the guide groove of the second snap-fit ​​part, and the assembly and disassembly can be completed quickly without additional tools, which improves the assembly efficiency; and the engagement of the first snap-fit ​​part and the second snap-fit ​​part can ensure the stable transmission of the transmission component and the curtain 250.

[0091] Please see Figure 14 , Figure 14This is a schematic diagram of the curtain fabric structure in some embodiments of this application. In some embodiments, the curtain fabric 250 includes a curtain body 251, a pull rod 252, and an edge strip 253. The pull rod 252 is disposed at the free end of the curtain body 251 and fixedly connected to the curtain fabric 250. The edge strip 253 is disposed at both ends of the curtain body 251 and is used to form a stable support structure during the operation of the curtain fabric 250. Specifically, the edge strip 253 can be precisely embedded in the claws of the guide rail 240, limiting the lateral displacement of the curtain body 251 through cooperation with the guide rail 240, and continuously providing longitudinal tension when the curtain fabric 250 is unfolded or retracted, ensuring that the curtain body 251 always remains flat and taut, avoiding wrinkles, jamming, or poor operation caused by slack, and significantly improving the stability of the curtain operation and the reliability of the sunshade effect.

[0092] The curtain body 251 can be made of high-strength, 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 and is firmly fixed to the free end of the curtain body 251 by precise riveting or bonding, thereby enhancing the rigidity of the end of the curtain 250, keeping it flat when unfolded, and also providing a stable stress point for the curtain 250.

[0093] Therefore, the structural design of the curtain 250 improves the overall structural strength and wind resistance of the curtain 250. Even when the vehicle is traveling at high speed, it can effectively prevent the curtain 250 from swaying or shifting, providing users with a more reliable and comfortable user experience, while extending the service life of the curtain.

[0094] The driving principle of the curtain 250 of the sunshade assembly 100 of this application is as follows: When the drive mechanism (motor) is started by the control switch, the rotation of the motor's output shaft drives the first transmission component 145 and the second transmission component 146 connected to it to move along the trajectory of the first set of through channels 147 and the second set of through channels 148. The movement of the first transmission component 145 and the second transmission component 146 is transmitted to the curtain 250 through the transmission connection component 270. Specifically, the pulling force of the first transmission component 145 and the second transmission component 146 acts on the slider 271, the slider 271 slides along the guide rail 240, and drives the connecting block 272 to move synchronously through the cooperation of the first locking part and the second locking part. The connecting block 272 then pulls the curtain body 251 connected to it, realizing the unfolding of the curtain 250. When the motor reverses, the first transmission component 145 and the second transmission component 146 move in opposite directions, and at the same time, the elastic element in the roller 220 releases the preload, assisting the roller 220 to wind and retract the curtain 250.

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

[0096] Thus, through the synergistic effect of the drive mechanism and the pre-tensioning force of the elastic element, the automatic control of the unfolding and rewinding of the curtain 250 is achieved, while reducing the load on the drive mechanism, reducing energy consumption, and extending the service life of the drive mechanism. In addition, through the design of the transmission connection component 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 pull rod 252 and the side strip 253 strengthen the structure of the curtain body 251, improve the overall deformation resistance and durability of the sunshade, and maintain a stable and reliable working state even in frequent use or complex environments, providing users with a long-term high-quality user experience.

[0097] In some embodiments, the locking method between the guide rail 240 and the first fixed seat 231 and the second fixed seat 232 may be as follows: the guide rail 240 has a first mounting groove and a second mounting groove extending along its extension direction; the first fixed seat 231 has a first slot adapted to the first mounting groove; and the second fixed seat 232 has a second slot adapted to the second mounting groove. When the first slot is inserted into the first mounting groove and the second slot is inserted into the second mounting groove, at least a portion of the first fixed seat 231 and the second fixed seat 232 are engaged with the guide rail 240.

[0098] During installation, align the first slot of the first fixing seat 231 with the first mounting slot of the guide rail 240, and align the second slot of the second fixing seat 232 with the second mounting slot. Press down to make the slots and mounting slots engage with each other.

[0099] Thus, through the precise matching of the slot and the mounting slot, the first fixing seat 231, the second fixing seat 232 and the guide rail 240 can be quickly installed and disassembled, which greatly improves the assembly efficiency, reduces labor costs, and forms a stable mechanical connection between the first fixing seat 231, the second fixing seat 232 and the guide rail 240. This effectively resists the vibration and external impact during vehicle operation, ensures that the sunshade assembly remains stable during long-term use, and reduces abnormal noises and malfunctions caused by loose parts.

[0100] Please continue reading. Figure 1 In some embodiments, the first crossbeam 120 is disposed 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 at intervals along the width direction of the first crossbeam 120.

[0101] Thus, the first frame curtain assembly 201 and the second frame curtain assembly 202 are arranged at intervals along the width direction of the first crossbeam 120, which can reasonably allocate the two sunshade curtain assemblies in the limited roof space, avoid the waste of space caused by structural overlap, and make the roof layout more compact and orderly, so that the first drive mechanism 131 and the second drive mechanism 132 drive the corresponding transmission components respectively to drive the corresponding curtains to move.

[0102] Alternatively, please see Figure 15 , Figure 15 This is another structural schematic diagram of the sunshade assembly in some embodiments of this application. In some embodiments, the first crossbeam 120 is disposed at one end of the first panel region 101 away from the second panel region 102, or the first crossbeam 120 is disposed at one end of the second panel region 102 away from the first panel region 101.

[0103] Please refer to the following: Figure 16 , Figure 16 for Figure 15 The diagram shows the structure of the central crossbeam. Thus, when the first crossbeam 120 is located at the end of the first panel area 101 away from the second panel area 102, or when the first crossbeam 120 is located at the end of the second panel area 102 away from the first panel area 101, the sunshade assembly 100 further includes a central crossbeam 180, on which a roller 220 for the first frame curtain assembly 201 and the second frame curtain assembly 202 is mounted.

[0104] Thus, by setting a central crossbeam 180 in the sunshade assembly 100 and integrating the rollers 220 of the first frame curtain assembly 201 and the second frame curtain assembly 202 onto it, the central crossbeam 180 provides a stable and uniform support carrier for the rollers 220, improving the structural strength and installation accuracy of the sunshade system, ensuring the smooth rotation of the rollers, and making the curtain unfolding and winding actions more stable; it also optimizes space occupation and facilitates the coordinated work of various components.

[0105] Please see Figure 17 , Figure 17 This is another structural schematic diagram of a vehicle in some embodiments of this application. In some embodiments, the first crossbeam 120 includes two beams, which are respectively disposed at one end of the first panel region 101 away from the second panel region 102 and at one end of the second panel region 102 away from the first panel region 101.

[0106] The two first crossbeams 120 are respectively set at the end of the first panel area 101 away from the second panel area 102 and at the end of the second panel area 102 away from the first panel area 101. This can form independent and targeted edge support and structural reinforcement for different panel areas, effectively disperse the external forces on each panel area, improve the structural stability of the first panel area 101 and the second panel area 102, avoid deformation of the transparent panel or the surrounding injection-molded structure due to concentrated force on one side, and extend the service life of the overall structure.

[0107] Therefore, a first drive mechanism 131 and a second drive mechanism 132 are respectively provided in the two first crossbeams to drive the curtains 250 of the first frame curtain assembly 201 and the second frame curtain assembly 202 to move respectively.

[0108] Therefore, the position and number of the first crossbeam 120 can be set according to the actual situation, and can also drive the first transmission component 145 and the second transmission component 146. It can be installed in different positions of the vehicle according to the design requirements of different vehicle models, so as to adapt to various vehicle structures.

[0109] Please see Figure 18 , Figure 18 This is a structural block diagram of a vehicle according to some embodiments of this application. In some embodiments, the vehicle 300 includes a body 310 and a sunshade assembly 100 as described in any of the foregoing embodiments, the sunshade assembly 100 being connected to the body 310.

[0110] Thus, by connecting the aforementioned sunshade assembly 100 to the vehicle body 310, the vehicle 300 fully leverages the advantages of the sunshade assembly 100, such as independent zone control, compact structure, and stable transmission: it not only meets the personalized sunshade needs of different areas inside the vehicle and improves driving comfort, but also ensures its compatibility with the vehicle body 310 through its precise positioning structure, reducing the risk of assembly interference. At the same time, its compact internal layout adapts to the limited space of the vehicle, thereby improving the overall functionality and structural reliability of the vehicle 300.

[0111] Please see Figure 19 , Figure 19 This is a flowchart illustrating a processing and assembly method for a sunshade assembly according to some embodiments of this application. In some embodiments, the processing and assembly method for the sunshade assembly includes the following steps: Step S10: At least a first set of through channels and a second set of through channels are pre-embedded in the mold cavity; Step S20: Inject molten plastic solution into the mold cavity to integrally form the transparent panel and the first crossbeam. The transparent panel includes a first panel area and a second panel area. The first crossbeam is 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.
