Description

Technical Field

[0001] This utility model relates to a recreational fitness equipment, specifically a recreational fitness equipment with a biomimetic flapping wing flight structure. Background Technology

[0002] Being able to fly freely in the sky like a bird and enjoy the beautiful scenery overlooking the earth from high altitude is a dream pursued by many people. In order to obtain such an experience, some people choose to achieve it through paragliding, wingsuit flying, and other methods. However, these methods require a high level of expertise from the operator and have poor safety, making them unsuitable for the general public.

[0003] In recent years, the application of rotary-wing drones has become increasingly widespread. Rotary-wing drones have many advantages, such as simple mechanical structure, excellent vertical takeoff and landing and hovering performance, low requirements for takeoff sites, and simple and convenient operation. Currently, some large rotary-wing drones used for cargo can carry a payload of over 200 kg. Some operators fix a frame-type seat under the large rotary-wing drone, allowing them to sit in the seat and control the drone, thus achieving manned flight. This method does not require high levels of expertise from the operator and is relatively safe. However, with this modification, the operator can only experience the feeling of looking down at the earth from the air while sitting in the seat, and cannot personally experience the feeling of soaring through the air. Moreover, these large rotary-wing drones have limited endurance when carrying a large load of passengers, resulting in insufficient flight time and distance. Utility Model Content

[0004] The purpose of this invention is to provide an entertainment and fitness equipment with a biomimetic flapping wing flight structure. The equipment is suspended below a large rotary-wing drone. The operator, sitting in the equipment seat, controls the drone to lift the entire equipment to a certain height. Then, the operator manually controls the flapping wings of the equipment to achieve biomimetic flight. This allows users to experience the feeling of soaring and looking down at the earth from the sky while enjoying entertainment and fitness. In addition, it can reduce the drone's load and increase its endurance.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A recreational fitness device with a biomimetic flapping wing flight structure includes a main frame with a seat for the operator positioned in the center. Flapping wings extending outwards are hinged to the left and right sides of the main frame above the seat via horizontally longitudinal side wing shafts. Each flapping wing is composed of a center plate and a tail plate. The inner edge of the center plate is hinged to the side wing shafts of the main frame via bushings, allowing the center plate to pivot around the side wing shafts. The outer edge of the center plate is connected to the inner edge of the tail plate via a lower... The square hinges are connected together, allowing the wingtip to swing around the outer edge of the wing center plate. When the wingtip swings upward to its maximum angle, it is flush with the wing center plate. Both the wing center plate and the wingtip have multiple air vents on their surfaces. The bottom surfaces of both plates have one-way valves that open downwards in one direction and resiliently return to seal the air vents at the corresponding positions. The top and bottom surfaces of the wingtip are fixedly connected to upper and lower lugs near the inner edge of the wingtip, respectively. The main frame is on the left... Two upper fixed pulleys are mounted on the upper inner sides of the right wing shafts via upper brackets. Each upper fixed pulley is equipped with two upper pull ropes, one end of which is fixedly connected to the upper lug of the tail plate on the same side. The other end of the rope passes upwards over the upper fixed pulley on the same side and extends vertically downwards, where a hand-held hook is fixedly connected. The two hand-held hooks are suspended above the front of the seat for the operator to grasp with both hands. The main frame is mounted on the lower inner sides of the left and right wing shafts via lower brackets. The frame is equipped with two lower fixed pulleys on the left and right, and each lower fixed pulley is equipped with two pull ropes on the left and right. One end of the pull rope is fixedly connected to the lower hanging lug of the tail plate on the same side, and the other end of the pull rope passes down around the lower fixed pulley on the same side and extends vertically downward, and is fixedly connected to a foot pedal ring at the end. The two foot pedal rings are suspended below the front side of the seat for the operator's dangling feet to pass through. The main frame is also equipped with a main lifting lug at the top center of its upper support for lifting the equipment as a whole.

[0007] This equipment is suspended from a large rotary-wing drone by ropes. The operator, seated in the equipment's seat, controls the drone to lift the entire device to a certain altitude, then switches the drone to auto-follow mode. The operator then grasps the handrails on the left and right sides above the seat and the footrests on the left and right sides below the seat. By alternately contracting and extending their limbs, the operator moves the flapping wings up and down. When the wings move upwards, the wing center plate and tail plate contract and bend, and the one-way valves on the flapping wings automatically open, reducing airflow resistance and decreasing the drag of the flapping wings. When the wings move downwards, the wing center plate and tail plate expand and flatten, and the one-way valves on the flapping wings automatically close, increasing airflow resistance and generating greater lift. This mimics the flapping motion of birds, providing the equipment with a certain degree of flight assistance. While using their hands and feet to control the flapping wings for entertainment and fitness, operators can personally experience the feeling of spreading their wings and looking down at the earth from high above. In addition, it can reduce the drone's payload and increase its battery life. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings. In the description of the present invention, the directional terms "front," "rear," "left," and "right" are based on the accompanying drawings. Figure 1 and Figure 3 The orientation shown is defined from the perspective of the operator of this equipment.

[0017] like Figures 1-7 As shown, this equipment has a main frame 1, and a seat 2 for the operator is mounted in the center of the main frame 1. On the left and right sides of the main frame 1 above the seat 2, outwardly extending flapping wings 3 are respectively hinged via horizontal longitudinal side wing shafts 1.1. Each flapping wing 3 is composed of a center plate 4 and a tail plate 5. The inner edge of the center plate 4 is hinged to the side wing shafts 1.1 of the main frame 1 via bushings 4.1, allowing the center plate 4 to rotate around the side wing shafts 1.1 of the main frame 1. The outer edge of the center plate 4 is hinged to the inner edge of the tail plate 5 via a lower hinge 6, allowing... The wingtip 5 can rotate around the outer edge of the wing center plate 4. When the wingtip 5 rotates upward to its maximum angle, it is flush with the wing center plate 4. Both the wing center plate 4 and the wingtip 5 have multiple air holes 7 on their surfaces. The bottom surfaces of the wing center plate 4 and the wingtip 5 are provided with one-way valves 8 at the positions corresponding to each air hole 7. These valves can open downward in one direction and can elastically return to their original position to seal the air holes 7. The top and bottom surfaces of the wingtip 5 are fixedly connected to an upper lug 5.1 and a lower lug 5.2 near the inner edge of the wingtip 5, respectively. The main frame 1 is located above the inner side of the left and right wing shafts 1.1. Two upper fixed pulleys 9 are mounted on the upper bracket 1.2, and each upper fixed pulley 9 is equipped with two upper pull ropes 10. One end of the upper pull rope 10 is fixedly connected to the upper hanging lug 5.1 of the tail plate 5 on the same side. The other end of the upper pull rope 10 passes upward over the upper fixed pulley 9 on the same side and extends vertically downward, where a hand-held hanging ring 11 is fixedly connected. The two hand-held hanging rings 11 are suspended above the front of the seat 2 for the operator on the seat 2 to grab with both hands. The main frame 1 is supported by the lower bracket 1.3 on the inner side of the left and right wing shafts 1.1. The right side has two lower fixed pulleys 12, each equipped with a left and right pull rope 13. One end of the pull rope 13 is fixedly connected to the lower hanging lug 5.2 of the tail plate 5 on the same side. The other end of the pull rope 13 passes down around the lower fixed pulley 12 on the same side and extends vertically downward, where a foot pedal hanging ring 14 is fixedly connected. The left and right foot pedal hanging rings 14 are suspended below the front side of the seat 2 for the operator's dangling feet to slip through. The main frame 1 also has a main lifting lug 1.4 at the top center of its upper bracket 1.2 for lifting the equipment as a whole.

[0018] Furthermore, the seat 2 is a double-sided hanging seat made of soft rope to facilitate the operator's hand and foot extension movements when operating the flapping wing 3.

[0019] Furthermore, the hinge between the bushing 4.1 of the wing midplate 4 and the side wing shaft 1.1 of the main frame 1 adopts a large clearance fit of more than 40mm, and the upper hanger 5.1 and lower hanger 5.2 of the wing tail plate 5 are located near the front end of the wing tail plate 5. When the upper pull rope 10 pulls the entire flapping wing 3 upward, the leading edge of the flapping wing 3 is slightly higher than the trailing edge, which raises the flight pitch angle. When the lower pull rope 13 pulls the entire flapping wing 3 downward, the leading edge of the flapping wing 3 is slightly lower than the trailing edge, which lowers the flight pitch angle. Thus, the flight direction can be changed by adjusting the pull force to change the pitch angle of the two flapping wings 3.

[0020] Furthermore, the one-way valve plate 8 is provided with a fixed seat 8.1, a valve plate 8.2, and a torsion spring 8.3. The fixed seat 8.1 is installed on the side of the bottom surface of each air hole 7 of the wing midplate 4 and the wing tailplate 5. The valve plate 8.2 is hinged to the fixed seat 8.1 through a hinge shaft. The torsion spring 8.3 is fitted on the hinge shaft. The tension of the torsion spring 8.3 pushes the valve plate 8.2 to elastically block the air hole 7 from the bottom.

[0021] Furthermore, the leading corner of the outer edge of the tailplate 5 is set with a large rounded corner to reduce the wind resistance of the flapping wing 3 when moving forward.

[0022] Furthermore, the main frame 1 and the flapping wing 3 are both made of carbon fiber material to reduce the overall weight of the equipment.

[0023] This equipment is used by being suspended from a large rotary-wing drone via ropes. The operator sits on seat 2 of the equipment and is secured to the main frame 1 with a safety harness. The operator controls the drone to lift the entire equipment to a certain altitude, then switches the drone to auto-follow mode. The operator then grasps the handrails 11 on both sides above seat 2 and places their feet on the footrests 14 on both sides below seat 2. The operator first retracts their limbs to manipulate the upper pull rope 10, causing the flapping wing 3 to swing upwards. Figure 3 and Figure 4 As shown, at this time, the wing center plate 4 swings upward around the side wing axis of the main frame 1, while the wing tail plate 5 swings downward around the outer edge of the wing center plate 4. The wing center plate 4 and the wing tail plate 5 form a contracted bending state, and the one-way valves 8 on each wind hole 7 of the wing center plate 4 and the wing tail plate 5 automatically open, reducing airflow resistance and decreasing the resistance of the flapping wing 3 swinging upward, thus mimicking the bending shape of a bird's flapping wing and the situation where feathers separate to reduce wind resistance. Then the operator extends their limbs to manipulate the pull rope 13 to pull the flapping wing 3 downward, as... Figure 1 and Figure 2As shown, at this time, the wing center plate 4 swings downward around the side wing axis of the main frame 1, while the wing tail plate 5 swings upward around the outer edge of the wing center plate 4. The wing center plate 4 and the wing tail plate 5 form an unfolded planar state, and the one-way valves 8 on each wind hole 7 of the wing center plate 4 and the wing tail plate 5 automatically close, increasing airflow resistance and giving the flapping wing 3 greater lift. This mimics the unfolded shape of a bird's flapping wing and the way its feathers fold together to increase wind resistance and lift. The operator can alternately contract and extend their limbs to pull the flapping wings 3 up and down, which can provide some flight assistance to the equipment, loosen the ropes suspending the equipment, reduce the load of the drone, increase the drone's endurance, and allow the operator to personally experience the feeling of spreading wings and looking down at the earth from high altitude while controlling the flapping wings with both hands and feet for entertainment and fitness.

[0024] The above illustrations are merely typical embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
