Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an automotive sunroof air guide bracket. Background Technology

[0002] During vehicle operation, especially at high speeds, opening the sunroof generates significant wind noise due to air turbulence. When the vehicle reaches a certain speed, airflow rapidly enters the cabin through the sunroof opening, creating strong pressure fluctuations and eddies. This aerodynamic effect not only results in an uncomfortable high-frequency whistling sound but also causes a feeling of pressure on the eardrums of occupants due to the pressure difference. Wind noise intensity increases non-linearly with vehicle speed, becoming a significant factor affecting driving comfort.

[0003] To mitigate this issue, the traditional solution is to install an air deflector bracket at the leading edge of the sunroof frame. This component, typically made of engineering plastics or lightweight metal, uses a specific arc design to guide and divert oncoming airflow, causing some of the airflow to escape upwards along the windshield surface, thereby reducing the speed of the airflow directly entering the passenger compartment. This structure effectively reduces the peak intensity of wind noise, but the bracket itself is still exposed to the impact of high-speed airflow, and its fixing method has a mechanical linkage with the sunroof system.

[0004] Traditional air deflector brackets maintain constant physical friction with the sunroof glass or frame. Under vehicle bumps or high-speed vibrations, this contact causes continuous wear due to movement, leading to a decrease in the structural strength of the air deflector bracket, peeling of the surface coating, and consequently affecting the accuracy of airflow guidance. More seriously, wear debris may intrude into the sunroof sliding rail mechanism, interfering with the opening and closing function and ultimately shortening the overall lifespan of the sunroof system. Utility Model Content

[0005] The purpose of this utility model is to provide a car sunroof air guide bracket that solves the problem of wear and tear caused by long-term contact between the traditional air guide bracket and the sunroof.

[0006] To achieve the above objectives, this utility model provides an automotive sunroof air guide bracket, including a base, a movable frame rotatably mounted on the upper end of the base, rotating shafts fixedly mounted on the left and right ends of the movable frame, a torsion spring fixedly mounted between the rotating shaft and the inner side of the base, an inclined surface fixedly mounted on the front end of the movable frame, and two symmetrical guide mechanisms fixedly mounted on the upper end of the movable frame.

[0007] The guiding mechanism includes a connecting piece, and the connecting piece is fixedly installed on the upper side of the movable frame.

[0008] A damper is fixedly installed between the connecting piece and the upper surface of the movable frame, and a shaft is fixedly installed at the upper end of the connecting piece.

[0009] The lower end of the shaft frame is fixedly provided with a movable wheel, and a bearing is fixedly provided between the movable wheel and the shaft frame.

[0010] An air guide net is fixedly installed between the movable frame and the base, and a first connecting rod is rotatably installed on the rear side of the air guide net. The upper end of the first connecting rod is fixed to the bottom of the movable frame.

[0011] The lower end of the first connecting rod is rotatably connected to a second connecting rod, and the lower end of the second connecting rod is fixed inside the base.

[0012] The first connecting rod and the second connecting rod are connected by a rotating shaft, and a connecting rope is fixedly installed between the rotating shaft and the air guide net.

[0013] Mounting plates are fixedly installed at both ends of the base, and the mounting plates are connected to the vehicle body by fastening bolts.

[0014] Without requiring an external power supply, it achieves fully automated mechanical operation, significantly reducing system complexity and cost. By cleverly utilizing torsion springs to store and release energy, it provides reliable driving force to propel the movable frame upwards to the working position the moment the sunroof opens. During the sunroof closing process, when the sunroof cover contacts the movable wheel, the contact force is directly transmitted to the axle and presses down the connecting piece. The connecting piece overcomes the damper resistance, thereby driving the entire movable frame to rotate and fold downwards smoothly. This process is entirely triggered and driven by the sunroof's own opening and closing action, requiring no additional sensors or controllers. The structure is simple and efficient, and the operation is stable and reliable, greatly simplifying the installation and maintenance process. At the same time, it avoids the risk of failure from the electrical system and improves overall durability. Attached Figure Description

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Please see Figures 1-5 A car sunroof air guide bracket includes a base 1, a movable frame 2 rotatably mounted on the upper end of the base 1, rotating shafts 3 fixedly mounted on the left and right ends of the movable frame 2, a torsion spring 4 fixedly mounted between the rotating shafts 3 and the inner side of the base 1, an inclined surface 5 fixedly mounted on the front end of the movable frame 2, and two symmetrical guide mechanisms 6 fixedly mounted on the upper end of the movable frame 2. Each guide mechanism 6 includes a connecting piece 601, and the connecting piece 601 is fixedly mounted on the upper side of the movable frame 2. The base 1 serves as the mounting foundation and fixing platform for the entire device, providing support for other components. The movable frame 2 is the main frame for opening, closing, and flipping, bearing the guide mechanisms 6 and the air guide net 7, and rotating around the rotating shafts 3 under the drive of the torsion springs 4. The rotating shaft 3 is the rotation center between the movable frame 2 and the base 1, allowing the movable frame 2 to rotate smoothly. The torsion spring 4 is sleeved on the rotating shaft 3, and its two ends are fixed to the movable frame 2 and the base 1 respectively. When the movable frame 2 is pressed down, the torsion spring 4 is twisted and stores energy. When the external force is released, the torsion spring 4 releases its elastic force to drive the movable frame 2 to flip upward and unfold. The inclined surface 5 is located at the front end of the movable frame 2. When the movable frame 2 flips upward to the limit position, it contacts the internal structure of the base 1 and plays a role in limiting and stabilizing support. The guide mechanism 6 is fixed to the upper end of the movable frame 2. Its function is to contact the sunroof cover and receive the downward pressure when the sunroof is closed. The connecting piece 601 is the base of the guide mechanism 6 and is fixed to the movable frame 2.

[0024] A damper 602 is fixedly installed between the connecting plate 601 and the upper surface of the movable frame 2. A shaft bracket 603 is fixedly installed at the upper end of the connecting plate 601, and a movable wheel 604 is fixedly installed at the lower end of the shaft bracket 603. A bearing 605 is fixedly installed between the movable wheel 604 and the shaft bracket 603. An air guide net 7 is fixedly installed between the movable frame 2 and the base 1. A first connecting rod 8 is rotatably installed on the rear side of the air guide net 7. The upper end of the first connecting rod 8 is fixed to the bottom of the movable frame 2. The damper 602 is connected between the connecting plate 601 and the movable frame 2, providing damping resistance when the connecting plate 601 is pressed down, buffering the impact and controlling the downward pressing speed of the movable frame 2 to make it smooth. The shaft bracket 603 is fixed to the upper end of the connecting plate 601 and is the shaft bracket 604 for the movable wheel 604. The mounting bracket of 4 transmits the pressure borne by the movable wheel 604 to the connecting piece 601. The movable wheel 604 is mounted on the axle bracket 603 and directly rolls in contact with the closed sunroof cover, converting the linear closing motion of the sunroof cover into its own rolling motion, greatly reducing frictional resistance and wear. The bearing 605 is built between the movable wheel 604 and the axle bracket 603, ensuring that the movable wheel 604 can rotate around its own axis with extremely smooth low resistance. The air guide net 7 is a core functional component. One side of it is rotatably connected to the base 1. When unfolded, it guides and sorts the airflow entering from the sunroof, reducing wind noise and turbulence. When folded, it reduces its volume for storage. The upper end of the first connecting rod 8 is hinged to the bottom of the movable frame 2, and the lower end is connected to the second connecting rod 9 through the rotating shaft 10.

[0025] A second link 9 is rotatably mounted at the lower end of the first link 8. The lower end of the second link 9 is fixed inside the base 1. The first link 8 and the second link 9 are connected by a rotating shaft 10. A connecting rope 11 is fixed between the rotating shaft 10 and the air guide net 7. Mounting plates 12 are fixed at both ends of the base 1 and are connected to the vehicle body by fastening bolts 13. The upper end of the second link 9 is connected to the first link 8 via the rotating shaft 10, and the lower end is hinged inside the base 1. Together with the first link 8, it forms part of a four-bar linkage. The angle between the two links changes as the first link 8 moves. The rotating shaft 10 is the hinge between the first link 8 and the second link 9. The connection point allows the two to rotate relative to each other and change the included angle. One end of the connecting rope 11 is fixed to the rotating shaft 10, and the other end is fixed to the air guide net 7. When the movable frame 2 is pressed down, causing the first connecting rod 8 and the second connecting rod 9 to move and reduce the included angle between them on the side closer to the air guide net 7, the rotating shaft 10 is displaced, and the connecting rope 11 is pulled, thereby forcibly pulling the air guide net 7 to fold orderly towards the base 1 (rear). The mounting plate 12 is fixed on the left and right sides of the base 1, providing an interface plane for connection with the vehicle body. The fastening bolt 13 passes through the hole on the mounting plate 12, and finally locks the mounting plate 12 and the entire device firmly in the predetermined installation position on the vehicle body to resist driving vibration.

[0026] Working Principle: This device requires no power supply. Its operation relies primarily on the torsion spring 4 to provide driving force, enabling the automatic opening and closing of the movable frame 2. When the sunroof is open, the torsion spring 4 acts on the rotating shaft 3, pushing the movable frame 2 upwards, thus extending the entire device. The guide mechanism 6, including a connecting piece 601, a damper 602, a shaft bracket 603, a movable wheel 604, and a bearing 605, is fixedly installed on the upper end of the movable frame 2. The damper 602 ensures smooth movement, and the movable wheel 604 rotates flexibly through the bearing 605. At this time, the air guide net 7 is fully extended, acting as a guide to prevent high-speed wind from directly entering the vehicle, effectively reducing wind noise. When the sunroof is closed, the sunroof contacts the movable wheel 604, pushing the shaft bracket 603 downwards. The shaft bracket 603 drives the connecting piece 601 to compress the damper 602, thereby pressing down on the movable frame 2. During the compression process, the angle between the first link 8 and the second link 9 decreases, especially near the side of the air guide net 7. Connected by the rotating shaft 10, the connecting rope 11 pulls the air guide net 7 to fold backward, preventing it from folding forward, thus completing the storage of the air guide net 7. During this process, the torsion spring 4 is compressed and stores energy, preparing for the next opening. The mounting plate 12 is fixed to the vehicle body by the fastening bolts 13, ensuring the overall stability of the device. The entire opening and closing process is completed by the coordinated mechanical structure, requiring no external energy. In the open state, the air guide net 7 continuously optimizes airflow and improves comfort. When closed, the device folds compactly without affecting the normal operation of the sunroof. This design is simple and reliable, suitable for various automotive sunroof environments. It achieves efficient air guiding and noise reduction functions through component linkage, meeting user needs. The entire process is smooth and seamless, without any jamming, improving the practicality and durability of the sunroof system.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
