Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a roof decorative cover, including a frame 1, a plurality of fixing holes are provided inside the frame 1, the fixing holes are threadedly connected with fixing nails 2, the bottom of the fixing nails 2 is fixedly connected with a fixing block 3, the frame 1 is fixedly connected with a sliding component 4, the top of the sliding component 4 is fixedly connected with a connecting member 5, the surface of the connecting member 5 is provided with a threaded hole, the top of the threaded hole is fixedly connected with a plastic sun visor 7 by a bolt 6, one end of the plastic sun visor 7 is rotatably connected with a shrinking component 8, the outside of the shrinking component 8 is provided with a baffle 9, the inside of the baffle 9 is fixedly connected with a support rod 10, the surface of the support rod 10 is rotatably connected with a heat insulation component 11, and the top of the heat insulation component 11 is fixedly connected with a positioning block 12.

[0025] like Figure 2 As shown, the surface of the fixing block 3 is provided with a threaded hole, and the internal thread of the threaded hole is connected to the roof;

[0026] By matching the threaded holes on the surface of the fixing block 3 with the preset threaded structure of the roof and tightly screwing them together, a stable connection between the fixing block and the roof is achieved. This connection method not only simplifies the installation steps, but also enhances the stability and reliability of the connection, enhances the safety of the frame 1, and reduces loosening caused by vibration or bumps. The design of the threaded holes must accurately match the thread specifications of the roof to ensure sealing and load-bearing capacity, and the surface must be rust-proofed to extend the service life;

[0027] like Figure 3 As shown, the sliding assembly 4 includes two sets of sliding rods 401 fixedly connected to the inside of the frame 1, one side of the sliding rod 401 is fixedly connected to a screw rod 402, and one end of the screw rod 402 is rotatably connected to a drive motor 403;

[0028] Guided by the slide bar 401, the drive motor 403 drives the screw rod 402 to rotate, achieving precise linear motion, ensuring accurate control, improving stability and efficient power transmission. The appropriate screw rod 402 model and material should be selected according to the load size, movement speed and accuracy requirements in the actual application scenario to ensure the stability and durability of the system. Lubricant should be applied regularly or an automatic lubrication device should be installed to reduce friction between the screw rod 402 and the nut.

[0029] like Figure 3 As shown, the surface of the screw rod 402 is rotatably connected to the slider 404, and the top of the slider 404 is fixedly connected to the connecting member 5;

[0034] The reflective layer 1101 reflects sunlight to reduce heat absorption, the thermal insulation layer 1102 further isolates heat transfer, and the protective layer 1103 protects the internal materials and extends service life. This design effectively reduces the temperature inside the vehicle, improves riding comfort, and enhances the durability of the roof structure. The various layers of material must fit tightly to ensure thermal insulation. The reflective layer 1101 requires a high reflectivity material, and the thermal insulation layer 1102 requires good thermal insulation performance.

[0035] like Figure 5 As shown, the surface of the positioning block 12 is fixedly connected to a lifting ring 13, the interior of the lifting ring 13 is sleeved with a hook 14, and the bottom of the hook 14 is fixedly connected to the surface of the car.

[0036] The connection between the eye 13 and hook 14 secures the roof assembly to the vehicle's surface. This allows for easy installation and removal, while maintaining a secure connection and ensuring the assembly's stability during driving. Hook 14 must precisely align with the pre-determined hole on the vehicle's surface to ensure a reliable and secure connection. The surface of eye 13 should be treated with rust-proofing to enhance its weather resistance and extend its service life.

[0037] Working principle: through the setting of the sliding component 4, the driving motor 403 is started, the screw rod 402 rotates, and the surface of the screw rod 402 is connected to the slider 404, and the slider 404 drives the connecting part 5 to move back and forth. The surface of the connecting part 5 is fixedly connected to the plastic sun visor 7 by a thread, so as to flexibly control the extension and contraction of the sun visor. The user can easily adjust the expansion or contraction degree of the sun visor according to actual needs to adapt to the sunshade needs under different lighting conditions. The electric operation greatly simplifies the operation process and improves the convenience of use. The sun visor is made of plastic material, which is not only light and durable, but also can effectively block direct sunlight, thereby improving driving and riding comfort; through the setting of the heat insulation component 11, the surface of the positioning block 12 is pulled Hook 14 allows the heat insulation assembly 11 to cover the front windshield of the automobile. The reflective layer 1101 is made of a high-reflectivity material (such as an aluminum-coated film) and can effectively reflect infrared and visible light from sunlight back to reduce the amount of heat entering the vehicle. The heat insulation layer 1102 is located below the reflective layer 1101. Its main function is to absorb and block excess heat to prevent further heat transfer into the vehicle. This layer is made of a low-thermal-conductivity material (such as foam plastic) with good heat insulation properties. The protective layer 1103 is located at the innermost layer of the heat insulation assembly and is in direct contact with the front windshield of the automobile. Its main function is to protect the heat insulation assembly and the front windshield of the automobile from erosion and damage from the external environment, such as rain, wind, sand, bird droppings, etc. The protective layer is made of a wear-resistant and corrosion-resistant material (such as PVC). The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art known to professionals in this field.
