Description

Technical Field

[0001] The present invention relates to the technical field of flying cars, and in particular to a foldable fixed wind wing and a flying car. Background Art

[0002] As a car drives, it encounters air resistance, which can be divided into longitudinal, lateral, and vertical resistance. Air resistance is proportional to the square of vehicle speed, so the faster the vehicle, the greater the air resistance. Generally, the effects of air resistance on a car become very noticeable when the vehicle speed exceeds 60 km / h. To effectively reduce the effects of air resistance at high speeds, fixed winglets are designed. Their function is to create a fourth force on the car: adhesion to the ground. These winglets partially offset lift, controlling the car's buoyancy, reducing the effects of wind resistance, and allowing the car to stick closely to the road, thereby improving driving stability.

[0003] Currently, fixed wings are commonly found at the rear of vehicles. These inverted airfoils effectively reduce air resistance and fuel savings at high speeds. They also act as aerodynamic devices, providing downforce during high-speed cornering. However, existing technologies for movable fixed wings primarily employ small-angle movements and retractable systems at the rear of the vehicle, failing to meet the large-area, wide-angle requirements of flying cars. Summary of the Invention

The cam is connected to the control mechanism by a spring, and the cam is connected to the control mechanism by a spring. The cam is connected to the control mechanism by a spring.

[0007] The foldable fixed wind wing provided according to the present invention also includes two mechanism boxes corresponding to the connecting rod assembly, each of the mechanism boxes is fixedly installed in the front box, the load-bearing rod, the active rod and the rocker arm are all arranged in the mechanism box, and a mechanism box opening is provided on the front side of the mechanism box for the front ends of the upper connecting rod and the lower connecting rod to extend out.

[0008] According to the foldable fixed wind vane provided by the present invention, the rotary servo is located between the two mechanism boxes, and the housing of the rotary servo is fixedly installed in the front box.

[0009] According to the foldable fixed wind wing provided by the present invention, the two driving shafts of the rotary servo are respectively connected and fixed to the two connecting shafts through couplings, and the upper ends of the two bearing rods are respectively connected and fixed to the two connecting shafts.

[0010] According to the foldable wind-fixing wing provided by the present invention, a stopper is further fixedly provided in the mechanism box, and the stopper is located at the rear side of the active rod.

[0011] According to the foldable wind-fixing wing provided by the present invention, the lower end of the active rod is connected to the side wall of the mechanism box through a first rotating shaft, and the lower end of the rocker arm is connected to the side wall of the mechanism box through a second rotating shaft.

[0012] According to the foldable fixed wind wing provided by the present invention, a sliding groove is provided on the active rod, and the sliding groove is extended along the length direction of the active rod. A connected locking groove is provided at the lower end of the sliding groove, and an L-shaped limiting groove is formed between the locking groove and the sliding groove; a sliding column adapted to the L-shaped limiting groove is provided at the lower end of the load-bearing rod, and the sliding column can slide along the L-shaped limiting groove, and the sliding column can rotate within the L-shaped limiting groove.

[0013] According to the foldable wind-fixing wing provided by the present invention, a limiting rod extending toward the front end is further connected to the upper end of the load-bearing rod, and a limiting block protruding downward is provided at the end of the limiting rod.

[0014] According to the foldable wind-fixing wing provided by the present invention, a card slot corresponding to each of the lower connecting rods is provided at the lower edge of the wind-fixing wing plate. When the foldable wind-fixing wing is in the unfolded state, the card slot of the wind-fixing wing plate is engaged with the lower connecting rod to form a stable triangular structure between the lower connecting rod, the driven rod and the wind-fixing wing plate.

[0016] The foldable fixed wing provided by the present invention is installed in the front box of a flying car. By controlling the rotation of a rotary servo, it can drive the movement of two sets of connecting rod assemblies, thereby driving the fixed wing panel to expand or fold. When the rotary servo rotates clockwise, it can drive the load-bearing rod to swing forward, thereby causing the active rod, lower connecting rod, driven rod, upper connecting rod and rocker arm to deform, thereby causing the fixed wing panel to reach a predetermined position and achieve the deployment of the foldable fixed wing.

[0018] Therefore, the foldable fixed wing of the present invention is specially used for flying cars. The angle of the fixed wing plate changes greatly, which can provide downforce for the flying car during takeoff, meeting the flying car's requirements for fixed wing with large area and large angle change. It also has a simple structure, low failure rate and high reliability. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. 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.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be a communication between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0032] like Figures 1 to 6 As shown, the foldable fixed airfoil of an embodiment of the present invention is mounted on the front trunk of a flying car and includes a rotary servo 10, a fixed airfoil panel 4, and two connecting rod assemblies. The rotary servo 10 is drivingly connected to the two connecting rod assemblies, and the two connecting rod assemblies are respectively connected to the fixed airfoil panel 4. In other words, by controlling the rotation of the rotary servo 10, the two connecting rod assemblies can be driven to operate, thereby driving the fixed airfoil panel 4 to be deployed or folded.

[0033] Each connecting rod assembly includes a load-bearing rod 8, an active rod 7, a rocker arm 6, an upper connecting rod 2, a lower connecting rod 3, and a driven rod 5. The upper connecting rod 2 is located above the lower connecting rod 3, and the rocker arm 6 is located in front of the active rod 7. The length of the rocker arm 6 is greater than the active rod 7. The drive shaft of the rotary servo 10 is driven and connected to the upper end of the load-bearing rod 8, and the lower end of the load-bearing rod 8 can slide with the active rod 7. The front end of the upper connecting rod 2 is rotatably connected to the upper end of the driven rod 5, and the rear end of the upper connecting rod 2 is rotatably connected to the upper end of the rocker arm 6. The rocker arm 6 and the lower connecting rod 3 are rotatably connected via a rotating shaft. The front end of the lower connecting rod 3 is rotatably connected to the middle part of the driven rod 5, and the rear end of the lower connecting rod 3 is rotatably connected to the upper end of the active rod 7. The lower end of the driven rod 5 is fixedly connected to the wind-fixing wing 4, and a leading edge opening that is compatible with the wind-fixing wing 4 is provided at the leading edge of the flying car.

[0034] When the foldable fixed wind wing is in the stowed state, the angle between the lower connecting rod 3 and the active rod 7 is an acute angle, and the angle between the upper connecting rod 2 and the rocker arm 6 is an acute angle.

[0035] When the rotary servo 10 rotates clockwise, it drives the load-bearing rod 8 to swing forward, which in turn causes the active rod 7, lower connecting rod 3, driven rod 5, upper connecting rod 2, and rocker arm 6 to deform, causing the fixed airfoil 4 to reach the predetermined position. At this point, the angles between the lower connecting rod 3 and the active rod 7 are obtuse, and the angles between the upper connecting rod 2 and the rocker arm 6 are also obtuse, allowing the foldable fixed airfoil to unfold. At this time, the leading edge opening of the flying car opens to form an air intake channel, facilitating heat dissipation for the flying car's internal takeoff equipment or other equipment that requires air. When the foldable fixed airfoil is unfolded, the fixed airfoil 4 is subjected to the downward pressure of the airflow, providing downforce for the flying car during takeoff.

[0036] Conversely, when the rotary servo 10 rotates counterclockwise, it drives the load-bearing rod 8 to swing backward, which in turn causes the active rod 7, lower link 3, driven rod 5, upper link 2, and rocker arm 6 to deform, thereby folding and stowing the foldable fixed airfoil. At this point, the fixed airfoil 4 can block the leading edge opening of the flying car, which is suitable for both driving and flying modes. In other words, the fixed airfoil 4 can serve as the outer contour of the vehicle's leading edge during driving, reducing the weight of the vehicle's outer shell, which would otherwise be located there.

[0037] Therefore, the foldable fixed wing of the embodiment of the present invention is specially used for flying cars. The angle of the fixed wing plate 4 varies greatly, which can provide downforce for the flying car during takeoff, meeting the flying car's requirements for fixed wings with large areas and large angles. It also has a simple structure, low failure rate and high reliability.

[0038] In some embodiments of the present invention, the foldable fixed wing further includes two mechanism boxes 1 corresponding to the connecting rod assemblies. Each mechanism box 1 is fixedly mounted within the front trunk of the flying vehicle. The load-bearing rod 8, active rod 7, and rocker arm 6 are all disposed within the mechanism box 1. A mechanism box opening is provided at the front side of the mechanism box 1, through which the front ends of the upper connecting rod 2 and lower connecting rod 3 extend. When the foldable fixed wing is deployed, the opening at the leading edge creates an air intake channel between the two mechanism boxes 1, facilitating heat dissipation for the takeoff equipment within the flying vehicle or other air-requiring devices.

[0039] Specifically, the rotary servo 10 is located between the two mechanism boxes 1, and the housing of the rotary servo 10 is fixedly installed in the front box of the flying car. The rotary servo 10 has two left and right drive shafts, each of which is connected and fixed to two connecting shafts via a coupling 9. The upper ends of the two load-bearing rods 8 are respectively connected and fixed to the two connecting shafts, and the connecting shafts are rotatably connected to the side walls of the mechanism box 1. By setting up a rotary servo 10, the forward thrust and downward movement path required for the deployment of the wind-fixing vane 4 can be achieved. Due to the setting of the coupling 9 and the load-bearing rod 8, the rotary servo 10 will not be directly affected by the airflow pressure exerted on the wind-fixing vane 4.

[0040] The lower end of the active rod 7 is connected to the side wall of the mechanism box 1 via a first rotation axis, and the lower end of the rocker arm 6 is connected to the side wall of the mechanism box 1 via a second rotation axis.

[0041] Furthermore, a stopper 11 is fixedly provided in the mechanism box 1, and the stopper 11 is located at the rear side of the active rod 7. By providing the stopper 11, the active rod 7 can be stopped from continuing to move backward when the foldable fixed wind vane is folded and stored, thereby limiting the active rod 7.

[0042] Specifically, a slide groove 701 is provided on the active rod 7, and the slide groove 701 extends along the length direction of the active rod 7. A connected locking groove 702 is provided at the lower end of the slide groove 701, and an L-shaped limit groove is formed between the locking groove 702 and the slide groove 701. A sliding column 801 adapted to the L-shaped limit groove is provided at the lower end of the load-bearing rod 8. The sliding column 801 can slide along the L-shaped limit groove, and the sliding column 801 can rotate within the L-shaped limit groove. Through this sliding limit structure between the load-bearing rod 8 and the active rod 7, locking control between the load-bearing rod 8 and the active rod 7 can be achieved, so there is no need to set up other additional locking mechanisms, which reduces the weight of the overall structure.

[0043] Among them, a limiting rod 802 extending toward the front end is also connected to the upper end of the load-bearing rod 8, and a limiting block 803 protruding downward is provided at the end of the limiting rod 802.

[0044] When the foldable fixed wing is in the stowed state, the sliding column 801 is located in the locking groove 702 , and the limiting block 803 on the limiting rod 802 abuts against the lower connecting rod 3 .

[0045] When the rotary servo 10 rotates clockwise, it first drives the sliding column 801 on the load-bearing rod 8 to slide out of the locking groove 702 to release the lock, and then pushes the load-bearing rod 8 to swing forward, thereby driving the active rod 7 to swing forward until it reaches the predetermined position. During this process, the sliding column 801 on the load-bearing rod 8 slides from the lower end of the slide groove 701 to the upper end of the slide groove 701.

[0046] Conversely, when the rotary servo 10 rotates counterclockwise, it drives the load-bearing rod 8 to swing backward, thereby driving the active rod 7 to swing forward until it contacts the stopper 11. During this process, the sliding post 801 on the load-bearing rod 8 slides from the upper end of the slide groove 701 to the lower end of the slide groove 701. The load-bearing rod 8 then continues to swing backward, causing the sliding post 801 to slide to the far right along the locking groove 702, and the limit block 803 on the limit rod 802 presses the lower connecting rod 3.

[0047] According to the foldable wind-fixing wing provided by the present invention, a card slot 401 corresponding to each lower connecting rod 3 is provided at the lower edge of the wind-fixing wing plate 4. When the foldable wind-fixing wing is in the unfolded state, the card slot 401 of the wind-fixing wing plate 4 can be engaged with the lower connecting rod 3 to form a stable triangular structure between the lower connecting rod 3, the driven rod 5 and the wind-fixing wing plate 4.

[0048] The working principle of the foldable fixed wing of this embodiment is as follows:

[0049] During the deployment of the foldable fixed airfoil, the rotary servo 10 first drives the sliding post 801 on the load-bearing rod 8 to slide out of the locking groove 702 to release the lock, and then pushes the load-bearing rod 8 to continue to swing forward, driving the active rod 7 and other rods to deform accordingly, so that the connecting rod assembly reaches the predetermined position. After reaching the predetermined position, the lower edge of the fixed airfoil 4 engages with the lower connecting rod 3 through the locking groove 401, forming a stable triangular structure. Because the airflow pressure on the fixed airfoil 4 is directed obliquely downward, the greater the force, the more stable the triangular structure. At this time, the load-bearing rod 8 is perpendicular to the active rod 7 to support the entire connecting rod assembly. Therefore, through the above-mentioned stable triangular structure and vertical offset method, the stability of the fixed airfoil 4 after deployment can be guaranteed.

[0050] The stowage process of the foldable fixed airfoil is opposite to the above-mentioned deployment process. The rotary servo 10 rotates, driving the bearing rod 8 to swing backward, thereby causing the active rod 7 and other rods to deform accordingly, thereby driving the fixed airfoil 4 to retract. When the bearing rod 8 and the active rod 7 are nearly parallel, the lower block 11 blocks the active rod 7, while the bearing rod 8 continues to swing backward. The sliding post 801 on the bearing rod 8 slides along the locking groove 702 to the far right and locks. The limit block 803 on the limit rod 802 presses the lower connecting rod 3, thereby ensuring that the connecting rod assembly will not shake after stowage.

[0051] like Figure 7 As shown, an embodiment of the present invention further provides a flying car, comprising the foldable fixed wind wing of the above embodiment.

[0052] During takeoff, the foldable fixed wings are deployed, and the fixed wing panels 4 are subjected to downward pressure from the airflow, providing downforce for the vehicle during takeoff. The leading edge of the vehicle is now open, creating an air intake passage between the two mechanism boxes 1, facilitating heat dissipation for the vehicle's takeoff equipment and other air-requiring devices.

[0053] When the flying car is in the driving or flying mode, the foldable fixed airfoil is in the stowed state, and the fixed airfoil panel 4 is sealed at the leading edge opening to ensure the normal driving of the flying car.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
