Description

Technical Field

[0001] This utility model relates to the field of flying car technology, and in particular to a foldable windshield and a flying car. Background Technology

[0002] Cars encounter air resistance while driving. This resistance can be categorized into longitudinal drag, lateral drag, and vertical drag. Air resistance is directly proportional to the square of the vehicle's speed; therefore, the faster the speed, the greater the air resistance. Generally, the impact of air resistance becomes very noticeable when the speed exceeds 60 km / h. To effectively reduce the impact of air resistance at high speeds, a wing has been designed. Its function is to generate a fourth force on the car: adhesion to the ground. It can counteract some lift, control the car's upward movement, reduce the impact of wind resistance, and allow the car to stay close to the road, thereby improving driving stability.

[0003] Currently, winglets are commonly found at the rear of vehicles. The inverted airfoil effectively reduces air resistance and saves fuel at high speeds. As an aerodynamic device, the winglet also provides downforce for race cars during high-speed cornering. However, existing technologies primarily utilize small-angle adjustments and retractable winglets at the rear of the vehicle, which cannot meet the needs of flying cars for large-area, large-angle winglets. Utility Model Content

[0004] The primary objective of this invention is to provide a foldable windshield that can solve the problem that existing windshields cannot meet the needs of flying cars for large-area and large-angle changes.

[0005] The second objective of this invention is to provide a flying car.

[0006] This invention provides a foldable wing stabilizer installed in the front compartment of a flying car. It includes a rotary servo, a wing stabilizer, and two sets of linkage assemblies. The rotary servo is driven by both sets of linkage assemblies, and the two sets of linkage assemblies are driven by the wing stabilizer. Each linkage assembly includes a support rod, a drive rod, a rocker arm, an upper linkage, a lower linkage, and a driven rod. The upper linkage is located above the lower linkage, and the rocker arm is located in front of the drive rod. The drive shaft of the rotary servo is connected to the upper end of the support rod. The driving connection includes a lower end of the load-bearing rod that can slide with the active rod; the front end of the upper connecting rod is rotatably connected to the upper end of the driven rod, and the rear end of the upper connecting rod is rotatably connected to the upper end of the rocker arm, which is rotatably connected to the lower connecting rod; the front end of the lower connecting rod is rotatably connected to the middle of the driven rod, and the rear end of the lower connecting rod is rotatably connected to the upper end of the active rod; the lower end of the driven rod is fixedly connected to the wind-stabilizing wingplate, and a leading edge opening adapted to the wind-stabilizing wingplate is provided at the leading edge of the flying car.

[0007] The foldable wind vane provided by this utility model also includes two mechanism boxes corresponding to the connecting rod assembly. Each mechanism box 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. An 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 wind-stabilized wing provided by this utility model, the rotating servo is located between the two mechanism boxes, and the housing of the rotating servo is fixedly installed in the front box.

[0009] According to the foldable wind-stabilized wing provided by this utility model, the two drive shafts of the rotating servo are respectively connected and fixed to the two connecting shafts through couplings, and the upper ends of the two load-bearing rods are respectively connected and fixed to the two connecting shafts.

[0010] According to the foldable wind vane provided by this utility model, a stop block is also fixed inside the mechanism box, and the stop block is located on the rear side of the active rod.

[0011] According to the foldable wind-stabilizing wing provided by this utility model, 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 wind vane provided by this utility model, a sliding groove is provided on the active rod, the sliding groove extends along the length direction of the active rod, and a locking groove is provided at the lower end of the sliding groove, forming an L-shaped limiting groove 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, 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-stabilizing wing provided by this utility model, a limiting rod extending towards the front end is also 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 stabilizer provided by this utility model, the lower edge of the wind stabilizer plate is provided with a slot corresponding to each of the lower connecting rods. When the foldable wind stabilizer is in the unfolded state, the slot of the wind stabilizer plate engages with the lower connecting rod, so that a stable triangular structure is formed between the lower connecting rod, the driven rod and the wind stabilizer plate.

[0015] This utility model also provides a flying car, including the aforementioned foldable fixed wing; when the flying car takes off, the foldable fixed wing is in an unfolded state, and the leading edge opening of the flying car is open; when the flying car is in driving or flight mode, the foldable fixed wing is in a retracted state, and the fixed wing plate seals the leading edge opening.

[0016] The foldable wing provided by this invention is installed in the front compartment of a flying car. By controlling the rotation of a rotary servo, two sets of linkage assemblies can be driven to move, thereby causing the wing panel to unfold or fold away. When the rotary servo rotates clockwise, it drives the load-bearing rod to swing forward, which in turn causes the active rod, lower linkage, driven rod, upper linkage, and rocker arm to deform, thus bringing the wing panel to a predetermined position and unfolding the foldable wing. At this time, the leading edge opening of the flying car opens to form an air intake channel, facilitating the heat dissipation of the flying car's internal takeoff equipment or other equipment requiring air. In the unfolded state, the wing panel is subjected to downward airflow pressure, which can provide downforce for the flying car during takeoff.

[0017] Conversely, when the rotary servo rotates counterclockwise, it can drive the load-bearing rod to swing backward, thereby causing the active rod, lower connecting rod, driven rod, upper connecting rod and rocker arm to deform accordingly, realizing the folding and storage of the foldable windshield.

[0018] Therefore, the foldable wind-stabilized wing of this utility model is specifically designed for flying cars. The angle of the wind-stabilized wing plate can change significantly, which can provide downforce for the flying car during takeoff. This meets the flying car's requirement for a wind-stabilized wing with a large area and large angle change. Furthermore, the structure is simple, the failure rate is low, and the reliability is high. Attached Figure Description

[0029] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] like Figures 1 to 6 As shown, the foldable wing of this utility model embodiment is installed in the front box of a flying car. It includes a rotary servo 10, a wing plate 4, and two sets of linkage assemblies. The rotary servo 10 is driven to the two sets of linkage assemblies, and the two sets of linkage assemblies are transmitted to the wing plate 4. That is, by controlling the rotation of the rotary servo 10, the two sets of linkage assemblies can be driven to move, thereby causing the wing plate 4 to unfold or fold into storage.

[0033] Each linkage assembly includes a support rod 8, a drive rod 7, a rocker arm 6, an upper link 2, a lower link 3, and a driven rod 5. The upper link 2 is located above the lower link 3, and the rocker arm 6 is located in front of the drive rod 7. The length of the rocker arm 6 is greater than that of the drive rod 7. The drive shaft of the rotary servo 10 is driven and connected to the upper end of the support rod 8, and the lower end of the support rod 8 can slide with the drive rod 7. The front end of the upper link 2 is rotatably connected to the upper end of the driven rod 5, and the rear end of the upper link 2 is rotatably connected to the upper end of the rocker arm 6. The rocker arm 6 and the lower link 3 are rotatably connected via a pivot. The front end of the lower link 3 is rotatably connected to the middle of the driven rod 5, and the rear end of the lower link 3 is rotatably connected to the upper end of the drive rod 7. The lower end of the driven rod 5 is fixedly connected to the windshield 4, and a leading edge opening adapted to the windshield 4 is provided at the leading edge of the flying car.

[0034] When the foldable windshield 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, thereby causing the active rod 7, lower connecting rod 3, driven rod 5, upper connecting rod 2, and rocker arm 6 to deform accordingly. This allows the wind-stabilizing wing 4 to reach a predetermined position. At this time, the angle between the lower connecting rod 3 and the active rod 7 is obtuse, and the angle between the upper connecting rod 2 and the rocker arm 6 is also obtuse, realizing the deployment of the foldable wind-stabilizing wing. Simultaneously, the leading edge opening of the flying car opens, forming an air intake channel, facilitating heat dissipation for the flying car's internal takeoff equipment or other equipment requiring air. In the deployed state, the wind-stabilizing wing 4 is subjected to downward airflow pressure, 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, thereby causing the active rod 7, lower connecting rod 3, driven rod 5, upper connecting rod 2, and rocker arm 6 to deform, achieving the folding and storage of the foldable wing. At this time, the wing plate 4 can block the leading edge opening of the flying car, a state suitable for both driving and flight modes. That is, the wing plate 4 can act as the outer contour of the car's leading edge during driving, reducing the weight of the car shell that would otherwise be located there.

[0037] Therefore, the foldable wind-stabilized wing of this utility model embodiment is specifically designed for flying cars. The wind-stabilized wing plate 4 has a large angle change, which can provide downforce for the flying car during takeoff, meet the flying car's requirement for a wind-stabilized wing with a large area and large angle change, and has a simple structure, low failure rate and high reliability.

[0038] In some embodiments of this invention, the foldable wind-stabilized wing also includes two mechanism boxes 1 corresponding to the linkage assembly. Each mechanism box 1 is fixedly installed inside the front box of the flying car. The load-bearing rod 8, the active rod 7, and the rocker arm 6 are all disposed inside the mechanism box 1. An opening is provided on the front side of the mechanism box 1 for the front ends of the upper linkage 2 and the lower linkage 3 to extend out. When the foldable wind-stabilized wing is unfolded, an air intake channel can be formed between the two mechanism boxes 1 through the opened leading edge opening, facilitating the heat dissipation of the takeoff equipment or other equipment requiring air inside the flying car.

[0039] Specifically, the rotary servo 10 is located between the two mechanism housings 1, and its housing is fixedly installed inside the front housing of the flying vehicle. The rotary servo 10 has two drive shafts, left and right, each connected and fixed to two connecting shafts via couplings 9. The upper ends of two support 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 housings 1. By setting up a single rotary servo 10, the forward thrust and descent motion paths required for the deployment of the windshield 4 can be achieved. Due to the couplings 9 and support rods 8, the rotary servo 10 is not directly subjected to the airflow pressure of the windshield 4.

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

[0041] Furthermore, a stop 11 is fixed inside the mechanism housing 1, located behind the drive rod 7. By setting the stop 11, the drive rod 7 can be prevented from moving further backward when the foldable wind vane is folded and stored, thus limiting the movement of the drive rod 7.

[0042] Furthermore, a sliding groove 701 is provided on the active rod 7, extending along the length of the active rod 7. A connecting locking groove 702 is provided at the lower end of the sliding groove 701, forming an L-shaped limiting groove between the locking groove 702 and the sliding groove 701. A sliding post 801, adapted to the L-shaped limiting groove, is provided at the lower end of the support rod 8. The sliding post 801 can slide along the L-shaped limiting groove and rotate within it. This sliding limiting structure between the support rod 8 and the active rod 7 achieves locking control between them, eliminating the need for additional locking mechanisms and reducing the overall structural weight.

[0043] Among them, a limiting rod 802 extending towards the front end is 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 wind vane is in the stowed state, the sliding post 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 pin 801 on the support rod 8 to slide out of the locking groove 702 to release the lock, and then pushes the support rod 8 to swing forward, so as to drive the active rod 7 to swing forward until it reaches the predetermined position. During this process, the sliding pin 801 on the support 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 support rod 8 to swing backward, causing the drive rod 7 to swing forward until it contacts the stop block 11. During this process, the sliding column 801 on the support rod 8 slides from the upper end of the slide groove 701 to the lower end of the slide groove 701. Then the support rod 8 continues to swing backward, so that the sliding column 801 slides along the locking groove 702 to the far right, and the limiting block 803 on the limiting rod 802 presses down on the lower connecting rod 3.

[0047] According to the foldable wind stabilizer provided by this utility model, a slot 401 corresponding to each lower connecting rod 3 is provided on the lower edge of the wind stabilizer plate 4. When the foldable wind stabilizer is in the unfolded state, the slot 401 of the wind stabilizer plate 4 can engage with the lower connecting rod 3 so that a stable triangular structure is formed between the lower connecting rod 3, the driven rod 5 and the wind stabilizer plate 4.

[0048] The working principle of the foldable windshield in this embodiment is as follows:

[0049] During the deployment of the foldable wing, the rotation of the servo motor 10 first causes the sliding column 801 on the support rod 8 to slide out of the locking groove 702 and release the lock. Then, it pushes the support rod 8 to continue swinging forward, causing the active rod 7 and other rods to deform together, so that the linkage assembly reaches the predetermined position. After reaching the predetermined position, the lower edge of the wing plate 4 engages with the lower connecting rod 3 through the slot 401, forming a stable triangular structure. Since the airflow pressure on the wing plate 4 is obliquely downward, the greater the force, the more stable the triangular structure. Moreover, at this time, the support rod 8 is perpendicular to the active rod 7 to hold the entire linkage assembly in place. Thus, through the aforementioned stable triangular structure and the perpendicular abutment, the stability of the wing plate 4 after deployment can be guaranteed.

[0050] The folding wing's retraction process: Reversing the deployment process described above, the rotary servo 10 rotates, causing the support rod 8 to swing backward, which in turn deforms the drive rod 7 and other rods, thereby retracting the wing plate 4. When the support rod 8 is nearly parallel to the drive rod 7, the lower stop block 11 blocks the drive rod 7, while the support rod 8 continues to swing backward. The sliding column 801 on the support rod 8 slides along the locking groove 702 to the rightmost position and locks. The limiting block 803 on the limiting rod 802 presses down on the lower connecting rod 3, ensuring that the connecting rod assembly does not shake after retraction.

[0051] like Figure 7 As shown, this utility model embodiment also provides a flying car, including the foldable fixed wing of the above embodiment.

[0052] When the flying car takes off, the foldable wing is in the deployed state, and the wing plate 4 is subjected to downward airflow pressure, providing downforce for the flying car during takeoff. At this time, the leading edge opening of the flying car opens, forming an air intake channel between the two sets of mechanism boxes 1, which facilitates the heat dissipation of the takeoff equipment or other equipment that requires air inside the flying car.

[0053] When the flying car is in driving or flight mode, the foldable wing is in a stowed state, and the wing plate 4 is sealed at the leading edge opening to ensure that the flying car can drive normally.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
