Description

Technical Field

[0001] This utility model relates to the field of automotive sunshades, specifically to a sunshade device. Background Technology

[0002] Traditional sunshade systems have significant drawbacks and are no longer suitable for the demands of modern vehicle bodies for maximum space utilization and performance upgrades. In terms of space occupancy, their curtain support relies entirely on plastic beams, and the rear beams (5 and...) in the diagram... Figure 6 The second crossbeam serves as the core support and is designed as an integral structure, which, when combined with the sunshade assembly, occupies a large space, conflicting with the current requirements for maximizing vehicle space. In new energy vehicles or compact models, this can easily lead to insufficient space and incompatibility, and it can also overlap with surrounding components such as the sunroof mechanism and roof electrical wiring harness.

[0003] In the assembly and maintenance process, the integrated design of the rear beam makes the assembly process complex and requires extremely high precision. Even a slight error can cause the curtain to jam, increasing the production line debugging cost. In the later maintenance, a large number of peripheral components (such as the roof and skylight frame) need to be disassembled before the work can be carried out, and the plastic parts often need to be replaced as a whole after damage, which is time-consuming and uneconomical.

[0004] Furthermore, vibrations and bumps during vehicle operation, as well as the repeated unfolding and rewinding of the curtain, can easily cause loosening and cracking at the connection points, leading to abnormal noises, curtain misalignment, and even overall structural failure. Simultaneously, the plastic beams themselves have limited resistance to deformation; after prolonged exposure to curtain tension and vehicle operating conditions, they are prone to creep, resulting in decreased curtain flatness. This affects both the sunshade effect and the interior aesthetics. There is an urgent need to develop a sunshade device that requires minimal space and has high structural strength. Utility Model Content

[0005] The purpose of this utility model is to provide a sunshade curtain device that solves the problems of space occupation and structural strength of sunshade curtain devices.

[0006] To achieve the above objectives, this utility model provides a sunshade curtain device, including a sunshade curtain assembly, a first guide rail, a second guide rail, and a support device;

[0007] The support device includes a support beam, a first support block, and a second support block;

[0008] The sunshade assembly includes a curtain fabric, a pull panel, and a roller.

[0009] The support beam is arched, with a first support block and a second support block connected to its two ends respectively. The first support block and the second support block are respectively located at one end of the first guide rail and the second guide rail.

[0010] The roller is positioned between the first support block and the second support block. A curtain is wound on the roller, and a pull plate is provided at one end of the curtain. The two ends of the pull plate are slidably connected to the first guide rail and the second guide rail, respectively.

[0011] The support beam can support the curtain fabric.

[0012] Preferably, the support beam is made of aluminum and tensions and supports the curtain fabric through its arched top.

[0013] Preferably, the support beam has an internally hollow structure.

[0014] Preferably, the top of the arched support beam is positioned higher than the position of the scroll.

[0015] Preferably, the support beam is disposed on the side of the reel close to the first guide rail and the second guide rail.

[0016] Preferably, it also includes a second crossbeam, the two ends of which are respectively connected to the other end of the first guide rail and the other end of the second guide rail;

[0017] The support beam is arranged parallel to the second crossbeam, and together they provide lateral support for the first guide rail and the second guide rail.

[0018] Preferably, both the first support block and the second support block are integrally injection molded from reinforced plastic and have a multi-dimensional reinforcing rib network structure.

[0019] Preferably, the first guide rail and the second guide rail are arranged in parallel, and both the first guide rail and the second guide rail are provided with buckles for connecting to the top trim panel.

[0020] Preferably, the pull plate is connected to the first guide rail and the second guide rail via a slider.

[0021] Preferably, the slider is a silent slider.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. This utility model adopts an arched support beam and a split support block structure to replace the traditional integral plastic rear beam support. The overall structure is divided into multiple modules, which reduces the space occupied and adapts to the space optimization requirements of new energy and compact models. On the other hand, the modular structure facilitates seamless integration and quick installation with the vehicle interior. At the same time, the split design avoids the problem of space overlap of the overall structure.

[0024] 2. This utility model uses the top of the arched support beam to tension and support the curtain fabric. The support beam and the curtain fabric form a bridge-like stress structure, which significantly improves rigidity and resistance to torsional deformation, and enhances support stability. The arched support beam is made of aluminum, which has significantly improved resistance to deformation and creep compared to traditional plastic beams. Combined with the mechanical advantages of the arched structure, it enhances the overall strength of the structure. The hollow design of the arched support beam reduces weight while ensuring strength.

[0025] 3. This utility model adopts a separate assembly structure of the first support block, the second support block, and the roller. The support block is integrally injection molded from reinforced plastic and has a multi-dimensional reinforcing rib network structure. The separate assembly simplifies the complex process of the traditional integral rear beam, reduces the assembly accuracy requirements, and reduces production line debugging costs. The reinforcing rib support block improves the connection strength, and subsequent maintenance does not require disassembling a large number of peripheral parts. Damaged parts can be replaced individually, improving the economic efficiency of operation and maintenance. Attached Figure Description

[0034] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0035] Example 1:

[0036] A sunshade device, such as Figure 1-4 As shown, the device includes a sunshade assembly 7, a first guide rail 3, a second guide rail 5, and a support device. The support device includes a support beam 2, a first support block 1, and a second support block 6. The sunshade assembly 7 includes a curtain fabric 8, a pull plate 9, and a roller 10. The support beam 2 is arched, with its two ends connected to the first support block 1 and the second support block 6, respectively. The first support block 1 and the second support block 6 are respectively located at one end of the first guide rail 3 and the second guide rail 5. The roller 10 is located between the first support block 1 and the second support block 6, and the curtain fabric 8 is wound on the roller 10. One end of the curtain fabric 8 is provided with a pull plate 9, and the two ends of the pull plate 9 are slidably connected to the first guide rail 3 and the second guide rail 5, respectively. The support beam 2 can support the curtain fabric 8.

[0037] The arched support beam 2 and the split support block structure are used to replace the traditional integral plastic rear beam support. The overall structure is divided into multiple modules, which reduces the space occupied and adapts to the space optimization requirements of new energy and compact models. On the other hand, the modular structure makes it easy to be seamlessly embedded and quickly installed with the vehicle interior. At the same time, the split design avoids the problem of space overlap of the overall structure.

[0038] like Figure 4 As shown, the top of the arched support beam 2 provides tension support for the curtain fabric 8, preventing wrinkles. The support beam 2 and the curtain fabric 8 form a bridge-like load-bearing structure. The arch shape is a recognized efficient load-bearing form, effectively converting external loads into pressure along the internal structure, thus achieving maximum load-bearing capacity with minimal self-weight. This significantly improves rigidity and resistance to torsional deformation, enhancing support stability. This ensures that the support device remains stable and quiet during repeated opening and closing of the sunshade device, with the curtain fabric 8 always maintaining uniform tension, ensuring smooth and reliable operation.

[0039] Furthermore, to improve the overall strength of the device, the material and structure of the support beam 2 and support block 6 are optimized. The support beam 2 is made of aluminum and tensions and supports the curtain 8 through its arched top. The support beam 2 has a hollow internal structure, increasing strength while reducing weight. Both the first support block 1 and the second support block 6 are integrally injection molded from reinforced plastic and have a multi-dimensional reinforcing rib network structure; for example, PP+LGF40 material is used. Compared with traditional curtain devices ( Figure 5 and Figure 6 Compared to traditional support devices, it features smaller footprint, lighter weight, and wider compatibility. Its core dimensions are 20% smaller and its total weight is reduced by approximately 18%.

[0040] Employing a highly integrated modular design, the traditional main frame support is replaced with a modular design of support beams and blocks for separate support. Furthermore, the headliner fixing clips can also be set as independent modules. This modular design significantly reduces the size of parts and assembly processes that are difficult to control, lowering the overall weight, complexity, and manufacturing costs. At the same time, the modular structure facilitates seamless integration and rapid installation with vehicle interior components (such as headliners and door panels). This achieves a high degree of integration and aesthetics between the sunshade device and the overall vehicle interior, enhancing the product's perceived quality and reliability.

[0041] Example 2:

[0042] This embodiment is an improvement upon Embodiment 1. Specifically, it includes a second crossbeam 4, with both ends connected to the other ends of the first guide rail 3 and the second guide rail 5, respectively. The support beam 2 is arranged parallel to the second crossbeam 4, jointly providing lateral support to the first guide rail 3 and the second guide rail 5. The first guide rail 3 and the second guide rail 5 are arranged parallel to each other, and both the first guide rail 3 and the second guide rail 5 are equipped with buckles for connection to the top trim panel.

[0043] The system employs a double transverse support structure with the support beam 2 and the second crossbeam 4 arranged in parallel. The double crossbeams provide stable transverse support for the guide rail, and the precise positioning of the guide rail buckles prevents misalignment and abnormal noise of the curtain caused by vehicle vibration and bumps. At the same time, the reliable connection between the guide rail and the top trim panel further optimizes the overall structural stability and solves the problems of easy failure under stress and reduced sunshade effect of traditional devices.

[0044] Support beam 2 effectively replaces the traditional front beam ( Figure 5 The first crossbeam 11) structure not only provides support for the front beam but also tensions and supports the curtain fabric 8, thus achieving a dual function. This eliminates the need for both front beam and curtain fabric support devices, further reducing the space occupied by the device.

[0045] Example 3:

[0046] This embodiment is an improvement on embodiment 1 or embodiment 2: the arched top of the support beam 2 is positioned higher than the roller 10, facilitating tension support for the curtain 8. The support beam 2 is positioned on the side of the roller 10 closest to the first guide rail 3 and the second guide rail 5, avoiding interference with the movement of the pull plate 9. The pull plate 9 is connected to the first guide rail 3 and the second guide rail 5 via a slider. The slider is a silent slider, which effectively reduces mechanical friction noise.

[0047] Furthermore, to address the stress concentration caused by the tension of the curtain fabric 8 and frequent opening and closing expansion and contraction, local thickening and topology optimization are carried out at key stress-bearing parts (such as the connection between the pull plate 9 and the slider, the connection between the slider and the two guide rails, and the connection between the roller 10 and the two support blocks) to effectively avoid the risk of fatigue fracture under long-term use.
