[0033] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0034] Please see Figure 1-5This utility model provides a technical solution: a split-integrated sunroof frame, which is located on the inner and outer sides of the car roof sheet metal, respectively, along with the sunroof system on the car roof. This split-integrated sunroof frame integrates functional modules such as a drainage system, insect screen, armrests, and roof light installation into a split-type structure. Specifically, the structure includes three core components: an inner panel assembly 1, an outer panel assembly 2, and an insect screen assembly 3.

[0035] Both the inner panel assembly 1 and the outer panel assembly 2 are square structures, and the center of each assembly has an opening for the inner panel assembly and an opening for the outer panel assembly adapted to the sunroof system. The inner panel assembly 1 has multiple first pre-clamping structures, second pre-clamping structures 12 and first threaded holes 14 on its edge. The first pre-clamping structures are clamped to the inner sheet metal of the vehicle body roof. The first threaded holes 14 are used to connect with bolts to the inner sheet metal of the vehicle body roof. As a core component, the inner panel assembly 1 is clamped to the vehicle body sheet metal through the pre-clamping structures and then fastened in place with bolts, providing a stable foundation support for the entire sunroof system.

[0036] The outer panel assembly 2 also has multiple third pre-clamping structures 21 and second threaded holes 22 on its edge; the first and third pre-clamping structures are compatible, so that after the outer panel assembly is pre-connected to the bottom of the inner panel assembly 1, the outer panel assembly is connected to the inner sheet metal bolts of the vehicle roof through the second threaded holes; this close fit between the inner panel assembly and the outer panel assembly not only improves the overall rigidity of the roof, but also enhances the sealing of the interior system, effectively preventing external debris from entering the cab.

[0037] The insect-proof net assembly 3 is sandwiched between the inner panel assembly and the outer panel assembly. The inner panel assembly and the outer panel assembly, together with the roof and the insect-proof net assembly 3, form a sandwich structure to prevent the roof from shifting and to improve the overall rigidity of the roof and the overall sealing performance of the interior system.

[0038] In some specific embodiments, the inner panel assembly 1 has a ring of water guide channels 11 arranged around its perimeter, adapted to the shape of the sunroof. The rear of the water guide channel 11 is higher than the front, forming a natural drainage slope to ensure that water can flow smoothly towards the front water guide channel. A drain outlet 12 is provided on each of the left and right sides of the front end of the water guide channel 11, and the drain outlet 12 is connected to the sunroof water pipe 4. When rainwater intrudes into the cab from the outside, or when condensation occurs inside the roof in wet and cold weather, this moisture is collected by the water guide channel 11 and discharged to the outside of the cab in a timely manner through the drain outlet 12 and the sunroof water pipe 4. This design effectively prevents moisture from penetrating into the roof and the cab, protecting the dryness of the cab and interior components, avoiding problems such as roof leakage and sheet metal corrosion caused by water leaks, and providing a dry and comfortable environment inside the cab.

[0039] In some specific embodiments, a sunroof grab handle 5 is integrated on the inner panel assembly 1. This grab handle is bolted to the vehicle body sheet metal via left and right through holes in the inner panel assembly. When the user opens or closes the sunroof, they can hold the grab handle to maintain balance and prevent falls due to instability while operating the sunroof, thus improving ease of operation and safety.

[0040] In some specific embodiments, the insect net assembly 3 includes a pair of parallel guide rails 31, with one side of the two guide rails 31 connected by a roller 32. The roller 32 is equipped with a spring assembly 33 connected to the two guide rails 31 to provide a closing force for the extension and retraction of the roller. An insect net 34 is provided between the spring assemblies. The side of the insect net 34 away from the roller is provided with a grooved operating frame 35 for manually pulling the insect net. The length of the operating frame 35 is adapted to the spacing between the guide rails, and both ends of the operating frame 35 are designed with locking buckles so that the insect net 33 can be locked and positioned with the ends of the guide rails 31 after being stretched into place. When the user manually pulls the operating frame 35, the insect net 32 ​​is slowly pulled out from the roller 34. Under the guidance of the two guide rails 33, the insect net 32 ​​gradually unfolds and covers the entire skylight ventilation opening. During this process, the retraction springs at both ends of the roller are stretched, generating a rebound force. After the operating frame 35 engages with the end of the guide rail 33, the unfolded state of the insect net 32 ​​is fixed, completely covering the sunroof vent and forming an effective physical barrier. This effectively prevents external insects, willow catkins, leaves, and other debris from entering the cabin, ensuring clean air inside the vehicle. When the insect net needs to be retracted, the engagement between the operating frame 35 and the end of the guide rail 33 is released. The spring assembly uses its own elastic potential energy to drive the roller 34 to rotate, rewinding the insect net 32 ​​back onto the roller 34, achieving automatic retraction of the insect net and restoring the sunroof to its normal closed state. This operation is convenient and highly practical.

[0041] More preferably, the insect-proof net assembly 3 is integrated with the inner panel assembly 1 and then connected to the outer panel assembly; specifically, the guide rail 31 is provided with mounting holes, and the inner panel assembly is provided with matching Boss columns; integrating the insect-proof net assembly with the inner panel assembly can provide frame support for the guide rail of the insect-proof net.

[0042] In some specific embodiments, the outer panel assembly 2 integrates the mounting structure of the cab interior light 6, effectively improving component integration, reducing layout space, and saving more living space for the user. Specifically, the outer panel assembly 2 is designed with mounting grooves for the interior light 6, the depth of which matches the thickness of the interior light, allowing the interior light 6 to be mounted on the grooves. This design effectively reduces the longitudinal height of the interior light 6, saving space occupied by the components and providing more interior living space for the user. It also facilitates component disassembly and repair during later market maintenance, reducing vehicle maintenance costs. The outer panel assembly 2 can be adjusted in size and shape to match different interior styles and the shapes of different interior lights 6, thus adjusting the exterior style.

[0043] During assembly, the inner panel assembly 1 is installed first and connected to the sunroof water pipe 4 to prevent malfunctions such as bends or blockages in the drain pipe during assembly. Then, the headliner and other interior trim products are installed. This assembly sequence effectively avoids malfunctions such as bends or loosening of the sunroof water pipe 4 during assembly, ensuring smooth drainage. When maintenance is required, the modular structure also makes disassembly and assembly of parts more convenient, reducing the user's vehicle maintenance costs.
