Description

Technical Field

[0001] This utility model relates to the field of vehicle modification products technology, specifically to a multifunctional rooftop luggage rack rotating sunshade. Background Technology

[0002] With the rise and development of self-driving tours, the vehicle modification industry is also booming. The core requirements for vehicle modification are lightweighting, quick assembly and disassembly, and multi-functional reuse, mainly focusing on modifications to the vehicle's space, energy system, comfort, and safety. Different vehicle models have different specific requirements. Vehicle modification needs to be tailored to the spatial structure, chassis characteristics, functional positioning, and daily usage scenarios of different models, with the core idea being to maximize the inherent advantages of the vehicle and minimize its weaknesses. All modification plans must adhere to the principles of compliance and non-destructive design to ensure that they do not affect the vehicle's annual inspection and driving safety.

[0003] Rooftop storage boxes and related accessories are often a focus of vehicle modifications, with various types and forms of modifications. However, overall, modifications to these structures suffer from the following key drawbacks: ① The decentralized layout of the various functional modules on the roof requires independent installation and fixation, which not only results in a bulky overall size and large space occupation, but also significantly increases the vehicle's drag coefficient, affecting driving stability and fuel efficiency. At the same time, the decentralized installation mode lacks a unified structural coordination design, resulting in poor compatibility between modules, making it difficult to maximize space utilization. Furthermore, the stacking of multiple modules can easily increase the load on the roof, posing a safety hazard.

[0004] ② The shading system lacks functional stability. The shading curtains are bulky, have cumbersome opening and closing mechanisms, and lack a targeted windproof structure design. When parked outdoors, they are easily affected by wind, resulting in unstable shading and heat insulation effects. Most importantly, their functions are relatively limited.

[0005] ③ Photovoltaic charging systems are limited by the installation angle, resulting in poor power adaptability. They cannot meet the power needs of vehicle electrical appliances and outdoor electrical equipment. In addition, together with integrated display devices, they rely on traditional wired transmission and control structures, resulting in low installation and usage flexibility.

[0006] Therefore, there is an urgent need for an integrated device that combines automatic wind and sun protection, high-efficiency charging, remote control, and customized size to address the shortcomings of existing technologies. Utility Model Content

[0007] To address the problems existing in the background technology, this application provides a multifunctional rooftop luggage rack rotating sunshade, which integrates the sunshade mechanism, photovoltaic charging mechanism, storage space and display mechanism into a whole, providing a multifunctional vehicle auxiliary device while ensuring driving safety.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a multi-functional roof rack rotating sunshade, mounted on the roof rack of a vehicle, characterized in that it includes a supporting body, a storage body, a photovoltaic charging mechanism, a multi-functional sunshade component, and an integrated display component; The supporting body is fixedly installed on the luggage rack via detachable components, providing a stable installation support base. The storage body is connected above the supporting body, and a rotating connection device is set between the two, enabling 0-360° rotation. The frame and panels of the storage body are interconnected to form a cuboid-shaped luggage storage space, and a photovoltaic charging mechanism is set on the top of the storage space as a space cover, while being connected to the vehicle-mounted energy storage device through a rotating conductive mechanism. In addition, the multi-functional sunshade component and the integrated display component are respectively installed on the outside of the side panel and end panel of the storage space. The vehicle-mounted energy storage device serves as the energy storage carrier for the photovoltaic charging mechanism through the conductive mechanism and supplies power to the integrated display component.

[0009] The supporting body is a rectangular frame with a crossbeam, which is horizontally mounted on the luggage racks at the front and rear ends of the roof and locked at the perpendicular intersection of the two by a buckle; a recessed cylindrical lower turntable is set at the geometric center of the rectangular frame, and a connecting hole is opened at the center of the lower turntable; a rolling bearing is installed in the connecting hole, and the rotating shaft passes through the rolling bearing and extends upward and downward respectively.

[0010] The base plate of the storage body is positioned opposite to the supporting body. It has a downwardly protruding cylindrical upper turntable that matches the concave cylindrical lower turntable, and a connection hole at its geometric center that is opposite to the lower rectangular frame. The part of the rotating shaft extending upward passes through the entire base plate and is fixed thereto, driving the entire storage body to rotate around the rotating shaft at any angle. A gap is left between the two turntables, and a positioning ring is provided at the connection between the rotating shaft and the base plate of the storage body to prevent direct contact with the base plate.

[0011] The photovoltaic charging mechanism is positioned above the main storage unit, conforming to the top size and shape of the storage space. It includes a bracket and a photovoltaic charging panel covering it, which serves as both a charging component and a cover for the storage space. One side of the bracket is hinged to the top outer side of any side panel of the storage space. Gas springs are installed at the bottom of both ends of the bracket, with the other end of each gas spring connected to the side of the main storage unit. The bracket also features a latch, allowing it to be retracted by the gas springs and integrated with the storage space. Wires are connected to the photovoltaic charging panel and to the vehicle-mounted energy storage device via conductive slip rings mounted on a rotating shaft, ensuring that the electrical connection of the circuit is not affected while the device is rotating.

[0012] The multi-functional sunshade assembly includes a sunshade curtain with a retractable shaft and a housing, which are respectively installed on the outer side of the front and rear end panels of the storage space, and a fixing device installed on the outer edge of the sunshade curtain; after the sunshade curtain is pulled out and unfolded, it is connected to the fixing point on the vehicle body or external device through the fixing device on the edge to achieve shading of the vehicle or the outer area of ​​the vehicle body.

[0013] Preferably, the fixing device for the edge of the sunshade is a magnetic fixing end or a mechanical hook that cooperates with the vehicle body fixing point.

[0014] The integrated display component includes two sets of LED displays fixed to the upper part of the two side plates of the storage body, as well as corresponding power supply lines, controllers, and editors; a heat insulation plate is set between the LED displays and the side plates to prevent heat from being transferred to the storage space; the power supply wires of the LED displays are connected to the vehicle-mounted energy storage device through conductive slip rings installed on the rotating shaft to supply power to it.

[0015] Preferably, at least two hooks and latches that cooperate with the supporting body are installed on the lower sides of the two side plates of the storage body; similarly, at least one hook and latch is provided on the crossbeam inside the supporting body to cooperate with the two side plates of the storage body; when the storage body is at 0° and rotated to 180° and 360°, the hooks and latches on the side plates are fastened to fix it to the supporting body and achieve limiting and locking; when the storage body is rotated to 90° and 270°, the hooks and latches on the crossbeam inside the supporting body cooperate with the hooks and latches on the two side plates of the storage body to fix it, which also achieves limiting and locking.

[0016] Preferably, the sunshade curtain is provided with a windproof structure, that is, according to the length and width of the sunshade curtain, several rows of ventilation holes are evenly arranged on its surface, and an air guide curtain is laid on the surface of the sunshade curtain in the area where the ventilation holes are set. The ventilation holes and the air guide curtain are combined to form an air leakage channel. The size of the air guide curtain should be able to block all the ventilation holes in the same row. The upper horizontal edge of the air guide curtain is connected to the sunshade curtain itself, while the lower horizontal edge remains separate. The ventilation holes and the air guide curtain are combined to form an air leakage channel. When the outside wind force is large, some of the wind blowing from below the sunshade curtain can flow out along the air leakage channel, reducing the force on the overall sunshade curtain and playing a windproof role.

[0017] Preferably, the air guide curtain has vertical connection points with the sunshade curtain at both sides and at the middle equidistant positions.

[0018] Preferably, a speed change mechanism and a corresponding micro drive motor are provided at the end of the downward extension of the rotating shaft, and the rotating shaft is driven and limited in position by the drive motor and the speed change mechanism.

[0019] In summary, this device is a multi-functional in-vehicle integrated device, with its core consisting of a supporting body, a storage body, a photovoltaic charging mechanism, a multi-functional sunshade component, and an integrated display component. It is mounted on the roof rack and follows the principle of compliance and non-destruction.

[0020] The main support is a rectangular frame, fixed to the luggage rack with buckles, and equipped with a turntable and rolling bearings for the rotating shaft to pass through. The storage body is also a rectangular frame, which can rotate 0-360° with the main support via a rotating connection device, forming a cuboid storage space. Hooks, buckles, and limiting gears are used between the two to achieve multi-angle limiting and locking. The photovoltaic charging mechanism serves as the cover of the storage space, including a photovoltaic charging panel and a bracket. It is retracted and extended by a gas spring and fixed with buckles, and connected to the vehicle's energy storage device via a conductive slip ring connector. The multi-functional sunshade assembly includes sunshade curtains and fixing devices on the outer sides of the front and rear end panels. The integrated display assembly consists of two sets of LED displays with heat insulation plates, both of which are powered by the vehicle's energy storage device via conductive slip ring connectors.

[0021] When the vehicle is in use, the storage body and the supporting body are locked together, the photovoltaic charging mechanism is retracted and locked, and the sunshade is retracted. The overall structure is compact, reducing wind resistance and not affecting driving safety. At the same time, the photovoltaic charging panel can charge the vehicle's energy storage device. After parking, the rotation angle of the storage body can be adjusted manually or by a micro drive motor, and it can be fixed by hooks or limit gears. The sunshade can be pulled out and fixed by a fixing device to provide sunshade for the front and rear windshields or the outer side areas of the vehicle. The LED display screen can display information through the controller and editor. The photovoltaic charging panel can be deployed by a gas spring to efficiently charge and power electrical appliances.

[0022] This device also has a significant effect on reducing energy consumption.

[0023] In scenarios involving sunlight exposure and idling with the air conditioning on, the fuel consumption of a typical family-owned 1.5L-3.0L vehicle idling with the air conditioning on for half an hour is 0.85-2.1L, and the CO emission is approximately 8-28g. Using the device described in this application, the interior temperature can be maintained at a suitable level under sunlight exposure, which can significantly reduce the air conditioning time, thereby saving fuel and reducing emissions. Beneficial effects

[0024] This technical solution integrates sunshade, photovoltaic charging, luggage storage, and information display functions into one unit. Adhering to the principle of compliance and non-destructive operation, it is mounted on the roof rack. The compact and rotatable structure, along with a multi-angle limiting and locking design, ensures stability during use. While driving, it reduces wind resistance, ensures driving safety, and provides continuous charging. When parked, the angle can be flexibly adjusted for precise sunshade. The photovoltaic charging panel provides efficient power supply when deployed, and the LED display can show various information. This solution solves the problems of traditional vehicle modification modules being scattered, having poor compatibility, and limited functionality, while also improving space utilization, flexibility, and practicality. Furthermore, when providing sunshade for the front and rear windshields, it can significantly reduce the interior temperature, reducing the use of air conditioning and other equipment. This reduces energy consumption, slows down the aging of interior facilities, and extends the vehicle's lifespan. Attached Figure Description
