DETAILED DESCRIPTION

[0005] Streamlined housing The streamlined shell (1) is directly attached to the roof of the vehicle, and its design is inspired by the principles of aerodynamics. With its streamlined appearance, the shell can effectively reduce the wind resistance of the vehicle during driving. A multifunctional flat platform (5) is provided on the shell, providing a user with a spacious flat space for placing luggage or installing equipment. An airflow evacuation bulge (11) is provided at the front end of the shell. The bulge can be designed as an integral part of the shell or installed separately, and its internal cavity can be used to store oil and other substances. The flat platform adjusts the front and rear height difference by connecting and fastening devices, further optimizing the air flow path, thereby reducing wind resistance and wind noise. After the shell is 3D modeled by software, the mold is made by CNC equipment processing, 3D printing or foam molding. In terms of material selection, plastic, carbon fiber, glass fiber and resin are used in combination, which not only ensures the high strength of the shell, but also realizes a lightweight design. The shell is firmly and reliably connected to the vehicle body, and is hard-connected to the vehicle through the connecting and fastening device. At the same time, a paint-resistant colloid similar to silicone structural adhesive is used to glue the shell to the vehicle body, ensuring the stability and durability of the platform.

[0006] Modular Link Fastening System The modular link fastening system is a key component of the roof platform, which is equipped with a cross bar (3) inside to ensure a stable connection between the platform and the roof. The rest of the cross bar adopts a hollow structure design and can serve as a storage compartment (2) or a liquid storage cavity. The cross bar is integrated with the roof through a hard link and is connected to the streamlined shell, serving as the internal support base of the shell, effectively improving the structural strength and stability of the entire platform. The modular link fastening system includes but is not limited to components such as adjustable hooks, clamps and quick-release screws, and has front and rear height adjustability, overall detachability, and reserved screw holes or rods for external mounting, so that users can flexibly adjust and expand according to actual needs.

[0007] Multifunctional flat platform The multifunctional flat platform (5) is the core functional area of ​​the roof platform, and is provided with an openable hole (4). The hole and the roof skylight form a passage, so that the user can directly reach the flat platform in the car, which is convenient for loading and unloading or entering and exiting the tent. The platform is pre-equipped with interfaces (51, 53, 13), which can be used for lifting or externally connecting solar panels, building tents outside the car when parking and camping, etc., greatly expanding the use scenarios and functions of the platform. The platform meets the roof luggage rack review specifications, the height does not exceed 30 cm, and the length and width do not exceed the car box, ensuring the driving safety and stability of the vehicle.

[0008] Storage compartment and liquid storage chamber When the hollow part of the crossbar is used as a storage compartment (2), a storage battery and a control and inverter device can be installed inside it, and it has functions such as emergency power supply or peak-shaving energy storage, providing convenience for outdoor electricity use. When it is used as a liquid storage cavity, it is equipped with a water inlet and outlet, a thermal insulation layer, and a removable filter. The streamlined shell (1) serves as the container shell, and the multifunctional flat platform (5) serves as the cover of the container. A baffle is arranged inside the reserved hole (4), which has a lower contact surface waterproof structural adhesive seal and an upper opening rubber strip seal together with the streamlined shell (1), and can be used to store drinking water or other liquids to meet outdoor water needs.

[0009] Standardized interface and quick installation The platform is equipped with standardized interfaces, which can be used to quickly install and disassemble solar panels and tent brackets without the need for complex tools, significantly improving the convenience of use. Specifically, the solar panel is fixed to the reserved interface of the platform through an adjustable bracket, and the bracket angle can be flexibly adjusted within the range of 0°-45°. The solar panel output power is 700 watts and is connected to the energy storage battery through a controller, thereby achieving efficient use of energy.

[0010] Multiple interfaces cooperate with each other In addition, the platform has a reserved equipment installation interface (51) and a reserved expansion equipment interface (53), which work together to connect the tent bracket or wall panel to ensure that the tent remains stable during use and will not shake or fall off. The materials used for the tent have good waterproof and windproof properties and are all high-performance fabrics that can fully meet the needs of outdoor use. In the normal state without expansion, the size of the tent is 2.4 meters long and 1.2 meters wide.

[0011] The multifunctional low wind resistance roof platform of the present invention realizes low wind resistance, multifunctional storage and convenient use through innovative design, meets the diverse needs of users in outdoor travel and camping, and has broad market prospects and application value.
