DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0034] Please refer to Figures 1-5 , an embodiment of the present invention provides a technical solution: a split integrated skylight frame, the frame and the skylight system on the top of the vehicle are respectively located inside and outside the body roof sheet metal; the split integrated skylight frame of the present invention integrates functional modules such as a drainage system, an insect screen, an armrest, and ceiling lamp installation into the split structure of the skylight frame. The specific structure includes three core components: an inner plate assembly 1, an outer plate assembly 2, and an insect screen assembly 3;

[0035] The inner panel assembly 1 and the outer panel assembly 2 are both square structures as a whole, and an inner panel assembly opening and an outer panel assembly opening adapted to the skylight system are respectively provided at the centers; a plurality of first pre - clamping structures, second pre - clamping structures 12 and first threaded holes 14 are provided at the edge of the inner panel assembly 1. The first pre - clamping structures are clamped with the inner sheet metal of the vehicle body roof; the first threaded holes 14 are used for bolt connection with the inner sheet metal of the vehicle body roof. As the core component, the inner panel assembly 1 is clamped on the vehicle body sheet metal through the pre - clamping structures and then fastened in place by bolts, providing a stable basic support for the entire skylight system.

[0036] A plurality of third pre - clamping structures 21 and second threaded holes 22 are also provided at the edge of the outer panel assembly 2; the first and third pre - clamping structures are adapted to each other. Thus, after the outer panel assembly is pre - connected to the bottom of the inner panel assembly 1, the outer panel assembly is bolt - connected to the inner sheet metal of the vehicle body roof through the second threaded holes; this close cooperation between the inner panel assembly and the outer panel assembly not only improves the overall stiffness of the roof but also enhances the sealing performance of the interior system, effectively preventing foreign objects from entering the cab.

[0037] The insect - proof net assembly 3 is clamped between the inner panel assembly and the outer panel assembly. The cooperation between the inner panel assembly and the outer panel assembly, together with the roof and the insect - proof net assembly 3, forms a sandwich structure, preventing the roof from moving and improving the overall stiffness of the roof and the overall sealing performance of the interior system.

[0038] In some specific embodiments, a water guide groove 11 is annularly arranged around the four - week edge of the inner panel assembly 1, which is adapted to the shape of the skylight; the rear part of the water guide groove 11 is higher than the front part, forming a natural drainage slope to ensure that the water flow can smoothly flow forward along the water guide groove; a drainage port 12 is provided on each of the left and right sides at the front end of the water guide groove 11, and the drainage port 12 is in plug - in fit with the skylight water pipe 4. When rainwater invades the cab from the outside or condensate water is generated inside the roof in wet and cold weather, these moisture will be collected by the water guide groove 11 and discharged to the outside of the cab in time through the drainage port 12 and the skylight water pipe 4. This design effectively prevents moisture from penetrating into the interior of the roof and the cab, protects the dryness of the cab and interior parts, and avoids problems such as roof water seepage and sheet metal corrosion caused by water leakage, providing a dry and comfortable environment inside the cab.

[0039] In some specific embodiments, a skylight armrest 5 is integrated on the inner panel assembly 1. The armrest is fixed to the vehicle body sheet metal by bolts through the left - right through - holes of the inner panel assembly. When the user opens or closes the skylight, the armrest can be held to maintain body balance, preventing the user from falling due to unstable body center of gravity during the operation of the skylight, improving the convenience and safety of the operation.

[0040] In some specific embodiments, the insect-proof net assembly 3 includes a pair of parallel guide rails 31. One side of the two guide rails 31 is connected by a reel 32. A spring group 33 connected to the two side guide rails 31 is installed on the reel 32 to provide a closing force for the expansion and contraction of the reel. An insect-proof net 34 is provided between the spring groups. On the side of the insect-proof net 34 away from the reel, there is an operation frame 35 with grooves for manually pulling the insect-proof net. The length of the operation frame 35 is adapted to the distance between the guide rails, and locking buckles are respectively designed at both ends of the operation frame 35 so that the insect-proof net 33 can be clamped and positioned with the ends of the guide rails 31 after being stretched in place. When the user can manually pull the operation frame 35 to drive the insect-proof net 32 to slowly withdraw from the reel 34, under the guiding action of the two side guide rails 33, the insect-proof net 32 gradually unfolds and covers the entire skylight ventilation opening. The spring groups for winding and unwinding at both ends of the reel are stretched during this process to generate a restoring force. After the operation frame 35 is clamped with the ends of the guide rails 33, the unfolded state of the insect-proof net 32 is fixed and completely covers the skylight ventilation opening, forming an effective physical barrier to effectively prevent foreign objects such as mosquitoes, catkins, and leaves from entering the cab, ensuring the cleanliness of the air inside the vehicle. When the insect-proof net needs to be retracted, the clamping connection between the operation frame 35 and the ends of the guide rails 33 is released, and the spring group drives the reel 34 to rotate back by virtue of its own elastic potential energy, rewinding the insect-proof net 32 back onto the reel 34 to realize the automatic retraction of the insect-proof net and restore the normal closed state of the skylight. The operation is convenient and the practicability is strong.

[0041] Further preferably, after the insect-proof net assembly 3 and the inner panel assembly 1 are integrated into one body, they are then connected to the outer panel assembly. Specifically, mounting through holes are provided on the guide rails 31, and the inner panel assembly is provided with matching Boss columns. Integrating the insect-proof net assembly with the inner panel assembly can provide a frame support for the guide rails of the insect-proof net.

[0042] In some specific embodiments, the outer panel assembly 2 integrates the installation structure of the cab interior lamp 6, effectively improving the part integration degree, reducing the layout space, and saving more activity space for the user. Specifically, an installation groove for the interior lamp is designed on the outer panel assembly 2, and the depth of the installation groove for the interior lamp matches the thickness of the interior lamp 6. The interior lamp 6 can be assembled on the groove. This design effectively reduces the longitudinal height of the interior lamp 6, saves the space occupied by the part, and provides more interior activity space for the user. During the later market user maintenance and repair, it is convenient for part disassembly and repair, reducing the vehicle use and maintenance cost. The outer panel assembly 2 can adjust the size and surface of the outer panel assembly according to different interior styles, and cooperate with the shapes of different interior lamps 6 to adjust the appearance style.

[0043] During the assembly process, first install the inner panel assembly 1 and connect it to the sunroof water pipe 4 to rule out failures such as kinking and blockage of the drain pipe during the assembly process. Then install the ceiling and other interior products. This assembly sequence can effectively avoid failure factors such as kinking and slack of the sunroof water pipe 4 during the assembly process and ensure smooth drainage. When maintenance is required, the split structure also makes it more convenient to disassemble and assemble parts, reducing the vehicle use and maintenance costs for users.
