[0035] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0036] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0037] According to some embodiments of this utility model, refer to Figures 1 to 5A sunshade structure is installed inside a car. The car includes a roof 100 and a sunroof 110. The sunroof 110 is located above the roof 100, and there is a gap 120 between the sunroof 110 and the roof 100. The sunshade structure includes a curtain body 200, a first positioning component 300, a second positioning component 400, and an elastic component 500. The first positioning component 300 is installed on the front side of the curtain body 200 and includes a plurality of first inserts 310. The plurality of first inserts 310 are arranged at intervals in the left-right direction, and the front side of the first inserts 310 is inserted into the gap 120 between the sunroof 110 and the roof 100. The second positioning component 400 includes two second inserts 410, which are respectively located on the left and right sides of the curtain body 200, and the second inserts 410 are inserted into the gap 120 between the sunroof 110 and the roof 100. The elastic component 500 is installed on the rear side of the curtain 200. The elastic component 500 includes a plurality of elastic blocks 510, which are arranged at intervals in the left-right direction. The rear side of the elastic blocks 510 is pressed against the ceiling 100.

[0038] Understandably, when the curtain 200 needs to be installed inside the car, the first insert 310 is inserted forward into the gap 120 between the sunroof 110 and the roof 100, the second insert 410 on the left side of the curtain 200 is inserted to the left into the gap 120 between the sunroof 110 and the roof 100, and the second insert 410 on the right side of the curtain 200 is inserted to the right into the gap 120 between the sunroof 110 and the roof 100. The rear side of the elastic block 510 is pressed against the roof 100, and the roof 100 reacts to the elastic block 510, causing the curtain 200 and the roof 100 to press against each other in the front-to-back direction, thus fixing them together. Specifically, after the elastic block 510 is compressed, its stored elastic potential energy is converted into a continuous forward thrust, acting on the entire curtain 200. The thrust firmly pushes the multiple first inserts 310 of the first positioning component 300 into and abuts against the front end of the gap 120 between the skylight 110 and the ceiling 100, thereby forming a reliable rigid positioning in the front-back direction. Simultaneously, the second inserts 410 of the second positioning component 400 provide lateral constraints, preventing the curtain 200 from moving laterally. Furthermore, the first inserts 310 and 410 in the gap 120 are jointly restricted from moving vertically by the ceiling 100 and the skylight 110. Ultimately, the curtain 200 is effectively locked in the front-back, left-right, and vertical directions, completely resolving the problem of incomplete constraints.

[0039] Furthermore, the elastic block 510, acting as an energy storage element, can automatically compensate for minor dimensional changes caused by temperature variations or long-term use, maintaining sufficient preload to ensure the stability and reliability of the curtain 200's long-term connection to the vehicle. The synergistic effect of the rigid positioning of the front first positioning component 300 and the elastic preload of the rear elastic component 500 makes the installed sunshade function like a single integrated unit, effectively suppressing vibration and displacement, thereby eliminating sources of abnormal noise, preventing the risk of detachment, and greatly improving vehicle quietness and driving safety. Moreover, the curtain 200 requires no additional tools during installation and can be completed by hand, offering high ease of installation. This sunshade structure is simple to install and provides a firm and stable assembly.

[0040] According to some embodiments of this utility model, refer to Figure 2 and Figure 3 A first crossbeam 210 is provided on the front side of the curtain body 200, extending in the left-right direction. A first positioning component 300 is installed on the first crossbeam 210. The first crossbeam 210 serves as a rigid mounting base for multiple first inserts 310, ensuring that all first inserts 310 can be inserted into the gap 120 synchronously and in the same direction during installation, and can jointly bear the preload from the elastic component 500 under stress, distributing the force evenly to the front edge of the curtain body 200. Secondly, the first crossbeam 210 enhances the structural rigidity of the front part of the curtain body 200, preventing the curtain body 200 material from wrinkling, deforming, or being damaged due to excessive local stress under the action of preload. The curtain body 200 material is usually a flexible fabric or composite material. Furthermore, the first crossbeam 210 simplifies the production and assembly process, allowing the first positioning component 300 to be pre-installed on the first crossbeam 210 to form a standardized front-end module, which is then connected to the curtain body 200. The first crossbeam 210 can be made of lightweight, high-strength materials, such as aluminum alloy profiles, engineering plastics, or carbon fiber composite materials, in order to reduce the weight of the assembly while ensuring sufficient rigidity and avoid putting too much burden on the vehicle roof 100.

[0041] According to some embodiments of this utility model, refer to Figure 2 and Figure 3 The first crossbeam 210 includes a first vertical plate 211 and a first horizontal plate 212. The lower end of the first vertical plate 211 is fixedly connected to the front side of the first horizontal plate 212. The first insert 310 includes a first fold 311 and a second fold 312. The rear end of the first fold 311 is connected to the upper end of the second fold 312. The front side of the second fold 312 is attached to the rear side of the first vertical plate 211. The second fold 312, the first vertical plate 211 and the curtain 200 are fixedly connected by a first bolt 320. The front end of the first fold 311 is inserted into the gap 120 between the skylight 110 and the ceiling 100.

[0042] Understandably, the cross-sectional shape of the first horizontal beam 210 is formed by the first vertical plate 211 and the first horizontal plate 212, creating an L-shape. This structure has a good bending section modulus, effectively resisting pressure from the front and rear directions and the weight of the curtain 200 itself, maintaining straightness. The second fold 312 serves as a mounting surface, providing a large area for contact with the rear side of the first vertical plate 211. It is fastened by the first bolt 320, resulting in high connection strength, good reliability, and easy disassembly and replacement. The first fold 311 is higher than the second fold 312, allowing the bolt holes corresponding to the first bolt 320 to be flexibly positioned on the first vertical plate 211. The first fold 311, which inserts into the gap 120, can still be precisely aligned with the gap 120 between the skylight 110 and the ceiling 100, enhancing adaptability and tolerance range.

[0043] According to some embodiments of this utility model, refer to Figure 3 The first insert 310 also includes a first elastic protective sleeve 330, which is fitted onto the first fold 311, meaning the first fold 311 is inserted into the inner cavity of the first elastic protective sleeve 330. The first elastic protective sleeve 330 provides protection. The first fold 311 is typically made of metal or hard plastic, with relatively sharp edges that could scratch the edge coating of the sunroof 110 glass or the velour material of the interior headliner 100 during insertion or long-term use. The first elastic protective sleeve 330 is typically made of soft silicone, TPE, or soft PVC. As a buffer layer, the first elastic protective sleeve 330 effectively avoids hard contact and protects the vehicle's interior. Furthermore, the first elastic protective sleeve 330 enhances friction and vibration damping. The elastic material surface of the protective sleeve typically has a high coefficient of friction, increasing the adhesion of the first fold 311 within the gap and further enhancing the stability of the fixation. Simultaneously, its flexible material can absorb and attenuate high-frequency micro-vibrations transmitted from the vehicle body, thereby eliminating abnormal noises. In addition, the first elastic protective sleeve 330 can improve the fit. Due to vehicle manufacturing tolerances, the width of the gap 120 between the sunroof 110 and the roof 100 is not completely consistent. The first elastic protective sleeve 330 has a certain degree of compressibility, which can fill and adapt to gaps 120 of different widths, achieving a tighter, gapless fit, thus improving the product's versatility and installation effect.

[0044] According to some embodiments of this utility model, refer to Figure 2 and Figure 4A second crossbeam 220 is provided on the rear side of the curtain 200, extending in the left-right direction. The elastic component 500 is mounted on the second crossbeam 220. The second crossbeam 220 is similar in material and function to the first crossbeam 210, providing a uniform and rigid mounting base for the multiple elastic blocks 510 at the rear. It ensures that the thrust generated by all the elastic blocks 510 can be integrated and evenly applied to the rear edge of the curtain 200, thereby pushing the curtain assembly 200 forward as a whole. This avoids uneven pressure on the rear edge of the curtain 200, preventing deformation or unevenness, and avoids inefficient force transmission that fails to form a stable and effective overall preload. The second crossbeam 220 ensures structural integrity and effective force transmission.

[0045] According to some embodiments of this utility model, refer to Figure 4 The second crossbeam 220 includes a second vertical plate 221 and a second horizontal plate 222. The lower end of the second vertical plate 221 is fixedly connected to the rear side of the second horizontal plate 222. The front side of the elastic block 510 is attached to the rear side of the second vertical plate 221. The elastic block 510 and the second vertical plate 221 are detachably and fixedly connected, and the rear side of the elastic block 510 presses against the ceiling 100. The second crossbeam 220 is L-shaped, and the front side of the elastic block 510 is attached to the rear side of the second vertical plate 221 to ensure that the thrust can be effectively transmitted in the front-to-back direction. The rear side of the elastic block 510 is designed as the surface that contacts the ceiling 100. This surface has a large contact area to disperse pressure and avoid leaving indentations on the surface of the ceiling 100. The detachable connection design of the elastic block 510 makes it easy to replace the elastic block 510. If the elastic block 510 undergoes plastic deformation and elasticity decay due to long-term pressure, the user or maintenance personnel can easily replace it to restore the pre-tension of the sunshade and extend the service life of the product. On the other hand, replaceable elastic blocks 510 with different thicknesses or elasticities can be designed for different car models or roof 100 profiles, enhancing the modularity and adaptability of the product.

[0046] According to some embodiments of this utility model, refer to Figure 4The elastic block 510 has a through hole 511. The elastic component 500 also includes a second bolt 520 and a second nut 530. The second bolt 520 passes through the through hole 511 and is inserted into the second vertical plate 221. The nut of the second bolt 520 is located inside the through hole 511 and presses the elastic block 510 forward. The second nut 530 is located on the front side of the second vertical plate 221. The second bolt 520 and the second nut 530 are threaded together. The elastic block 510 is made of a material with good elasticity and durability, such as EPDM rubber, polyurethane foam, or silicone. The through hole 511 has a stepped portion. During installation, the second bolt 520 is inserted forward from the rear side of the elastic block 510, and its nut abuts against the stepped portion, thus being confined within the through hole 511. The bolt shank passes through a hole on the second vertical plate 221 and is threadedly connected to and tightened with the second nut 530 located on the front side of the second vertical plate 221. When the second nut 530 is tightened, the nut of the second bolt 520 presses forward inside the elastic block 510, thereby firmly clamping the elastic block 510 onto the second vertical plate 221. The elastic block 510, the second vertical plate 221, and the curtain 200 are fixedly connected by the second bolt 520.

[0047] According to some embodiments of this utility model, refer to Figure 5 The second insert 410 includes a third fold 411 and a fourth fold 412. One end of the third fold 411 is fixedly connected to the upper end of the fourth fold 412, and the fourth fold 412 is fixedly connected to the curtain body 200 by bolts. The other end of the third fold 411 is inserted into the gap 120 between the skylight 110 and the ceiling 100. The second insert 410 is L-shaped. The fourth fold 412 serves as a mounting base and is connected to the side of the curtain body 200 by bolts, ensuring the stability of the connection. The third fold 411 serves as an insertion part, and its direction is perpendicular to the fourth fold 412, facilitating horizontal insertion into the gap 120.

[0048] According to some embodiments of this utility model, refer to Figure 5 The second insert 410 also includes a second elastic protective sleeve 420, which is fitted onto the third fold 411, meaning the third fold 411 is inserted into the inner cavity of the second elastic protective sleeve 420. The second elastic protective sleeve 420 has the same material and effect as the first elastic protective sleeve 330, and will not be described further here. This achieves protection of the original vehicle interior, suppression of vibration and noise, and compensation for fit tolerances, collectively contributing to improving the product's quietness, safety, and installation quality.

[0049] According to some embodiments of this utility model, refer to Figure 5The curtain body 200 is provided with a positioning groove 430, and the lower end of the fourth fold 412 is provided with a positioning protrusion 440, which is inserted into the positioning groove 430. The positioning protrusion 440 is a square post, and the positioning groove 430 is a square slot. During installation, the positioning protrusion 440 is first aligned and inserted into the positioning groove 430, and then the bolts are tightened. This prevents the fourth fold 412 from rotating relative to the curtain body 200, ensuring that the third fold 411 always maintains the correct design angle after the second insert 410 is installed and during long-term use, thus ensuring that it can play a maximum lateral support role within the gap 120. Moreover, the cooperation between the positioning protrusion 440 and the positioning groove 430 provides the installer with a clear positioning reference, avoiding the tedious operation of repeatedly adjusting the angle, realizing fast and accurate blind operation assembly, and improving production efficiency and installation convenience.
