Description

Technical Field

[0001] The present invention relates to the technical field of aircraft, and in particular to a foldable twin-rotor aircraft and a working method thereof. Background Art

[0002] As the number of cars increases, traffic congestion becomes increasingly problematic, and the low-altitude economy is rapidly developing.

[0012] Based on the above-mentioned working method of a foldable twin-rotor aircraft, a foldable twin-rotor aircraft includes a driving state, a flight state, a take-off state and a landing state; When in motion, the propeller is stopped and the tail wing is inside the vehicle body; the vehicle body is driven by a driving device of the vehicle body, the foldable rotor is parallel to the direction of the vehicle body, the lift wing is in a retracted state, and the various connecting parts are separated and arranged in the vehicle body fixing grooves.

The top of the clamping rod is set in the positioning hole, the reinforced telescopic cylinder extends, and the driving column contacts the top plate. The reinforced telescopic cylinder continues to extend, and the driving column moves into the accommodating groove, driving the driving gear to rotate, so that the reinforcement arm rotates. When the spring connected to the driving column reaches the maximum compression amount, the reinforcement arm rotates to be perpendicular to the driving column and fits with the inner wall of the connecting part, so that the foldable rotor is transformed from a folded state that fits the vehicle body to a linear state; the rotating disk is started, and the foldable rotor is unfolded to 60°-120° with the direction of the vehicle body, the lift wing plate is transformed from a retracted state to an extended state, and the tail wing is raised under the action of the elevator and extends out of the vehicle body, and the vehicle body moves.

After the vehicle body stops in contact with the ground, the rotating disk is started to drive the foldable rotor to fold and rotate, so that the foldable rotor is parallel to the direction of the vehicle body. At the same time, the lift wing panel changes from the extended state to the retracted state, and the direction of the lift wing panel is adjusted to be consistent with the direction of the vehicle body fixing groove. The winch is started to loosen the connecting wire rope. Under the action of the spring, the active wedge block disengages from the passive wedge block, so that the clamping rod moves away from the fixed clamping ring, so that the various connecting parts are separated and set in the vehicle body fixing groove. After the buffer plate is subjected to the pressure of the connecting part, the top column squeezes the clamping plate, so that the two clamping plates clamp the connecting part, and the positioning ball head plunger is stuck in the positioning groove, so that the foldable rotor is converted from a linear state to a folding state that fits the vehicle body.

[0013] Preferably, when the vehicle body driving mechanism is a front-wheel drive, the vehicle body driving mechanism stops running after the vehicle body takes off, and the propulsion driving device drives the propeller to run. When in the driving state, the vehicle body driving mechanism runs to achieve front-wheel drive driving; When the vehicle body drive mechanism is a four-wheel drive, after the vehicle body takes off, the front drive part of the vehicle body drive mechanism stops running, and the rear drive part of the vehicle body drive mechanism continues to drive the propeller to run.

[0021] In order to reduce the resistance in the driving state, the foldable rotor 2 is in a linear state in the flying state and in a folded state that fits the vehicle body in the driving state. The foldable rotor 2 includes a plurality of connecting parts 21 connected in sequence. Figure 1Only three connection parts 21 are shown. The number of connection parts 21 can be increased according to actual design requirements to increase the extended length of the foldable rotor 2. A double connection mechanism is provided between adjacent connection parts 21. The connection part 21 at one end is installed on the vehicle body through a rotating folding mechanism, and a lift component is provided on the connection part 21 at the other end.

[0022] The double connection mechanism includes at least two circumferentially distributed hoists 23 and fixed connection components 24, such as Figure 2 and Figure 3 As shown, the hoist 23 is fixed in the connection part 21, and the free end of the connecting wire rope 231 of the hoist 23 is fixed in the adjacent connection part 21, realizing the conversion between the flexible state and the rigid state of the adjacent connection parts 21. The fixed connection assembly 24 realizes the reinforced connection of the adjacent connection parts 21 in the rigid state (linear state). The fixed connection assembly 24 includes a plurality of clamping rods 241 slidably arranged in the connection part 21, and a fixed clamping ring 245 is provided in the adjacent connection part 21. The circumferential side of the fixed clamping ring 245 is provided with a positioning hole 246. A slider 242 is provided on the side of the clamping rod 241. The slider 242 is arranged in the slide groove 211 of the connection part 21. The slider 242 is connected to the connection part 21 by a spring. A passive wedge block 243 is provided on the top of the clamping rod 241, and an active wedge block 244 is provided on the adjacent connection part 21, which is arranged opposite to the passive wedge block 243. When the winch 23 tightens the connecting wire rope 231, the active wedge 244 passes through the docking hole on the end face of the connecting part 21 to squeeze the passive wedge 243, so that the clamping rod 241 moves downward to fix the clamping ring 245 and enter the positioning hole 246 to achieve a reinforced connection between the two connecting parts 21.

[0023] In order to enhance the overall strength in flight, a telescopic reinforcement mechanism 5 is provided in the connecting portion 21. Figure 4 and Figure 5 As shown, the telescopic reinforcement mechanism 5 includes a reinforced telescopic cylinder 51 fixed in the connecting part 21, and a receiving groove 52 is provided at the top of the telescopic end of the reinforced telescopic cylinder 51, and a driving column 53 is connected to the receiving groove 52 through a spring. A top plate 54 is provided in the connecting part 21 and is arranged opposite to the driving column 53, and a plurality of circumferentially distributed driving racks 55 are provided on the circumferential side of the driving column 53. A plurality of circumferentially distributed connecting grooves 56 are provided on the circumferential side of the telescopic end of the reinforced telescopic cylinder 51 and communicated with the receiving groove 52, and a driving gear 57 is rotatably connected in the connecting groove 56, and the driving gear 57 is connected to the reinforcement arm 58, and the free end of the reinforcement arm 58 is semicircular.

[0024] The rotary folding mechanism includes a rotary disk 25 to achieve angle adjustment and height adjustment of the foldable rotor 2 .

[0025] In order to reduce the impact of the vehicle body 1 when the linear state is converted into the fitted state, a fixing mechanism 4 is provided on the vehicle body. Figure 6As shown, the fixing mechanism 4 includes a buffer plate 42 disposed within the vehicle body fixing slot 11 via a buffer spring 41. The vehicle body fixing slot 11 is configured based on the total length of the multiple connecting parts in an actual linear state and is not limited to the top of the vehicle body. The vehicle body fixing slot 11 can also extend to the rear of the vehicle. A top post 43 is provided at each end of the buffer plate 42. The top post 43 is disposed opposite one end of a clamping plate 44, which is hinged to the vehicle body. The other end of the clamping plate 44 is provided with a positioning ball plunger 45. The positioning ball plunger 45 is disposed opposite a positioning slot 212 on the side of the connecting part 21. When the connecting part 21 enters the vehicle body fixing slot 11, gravity forces it downward, causing the clamping plate 44 to approach the connecting part 21 and position the positioning ball plunger 45 within the positioning slot 212, thereby securing the connecting part 21 and preventing vibration of the connecting part 21 due to bumps during vehicle driving.

[0026] The propulsion mechanism 3 of this embodiment includes a propeller 31 installed at the rear of the vehicle body 1. The vehicle body is a front-wheel drive vehicle body. The rotating shaft of the propeller is connected to a propulsion drive device, and the propulsion drive device is independently provided with the driving mechanism of the vehicle body.

[0027] The lift component includes two lift wing panels 22 , which are telescopic wing panels. The lift wing panels 222 all adopt the existing telescopic wing panel structure.

[0028] The tail wing 6 is mounted on the vehicle body 1 via a lift (not shown). When the vehicle is moving, the tail wing 6 is inside the vehicle body 1. When the vehicle is flying, the tail wing 6 is extended to the outside of the vehicle body 1 by the lift.

[0029] This embodiment is based on the working method of the foldable twin-rotor aircraft described above, and the specific process is as follows: a foldable twin-rotor aircraft includes a driving state, a flight state, a take-off state, and a landing state; When in driving state, the propeller 31 is in a stopped state and the tail wing 6 is inside the vehicle body 1; the driving device of the vehicle body 1 is used to drive the vehicle body to move, the foldable rotor 2 is parallel to the direction of the vehicle body 1 and the lift wing panel 22 is in a retracted state, and each connecting part 21 is separated and arranged in the vehicle body fixing groove 11 of the vehicle body 1, the buffer plate 42 is subjected to the pressure of the connecting part 21, the top column 43 squeezes the clamping plate 44, so that the two clamping plates 44 clamp the connecting part 21, and the positioning ball head plunger 45 is stuck in the positioning groove 212, so that the foldable rotor 2 is in a folded state that fits the vehicle body 1.

[0030] When in take-off state, the winch 23 is started to tighten the connecting wire rope 231, so that each connecting part 21 overcomes the restriction of the positioning ball head plunger 45 and docks with the adjacent connecting part 21. During docking, the active wedge 244 squeezes the passive wedge 243, so that the clamping rod 241 moves toward the fixed clamping ring 245. The top of the clamping rod 241 is set in the positioning hole 246, and the reinforced telescopic cylinder 51 is extended. After the driving column 53 contacts the top plate 54, the reinforced telescopic cylinder 51 continues to extend, and the driving column 53 moves into the accommodating groove 52, driving the driving gear 57 to rotate, so that the reinforcement arm 58 rotates. When the spring connected to the driving column 53 reaches the maximum pressure When shrinking, the reinforcement arm 58 rotates to be vertically arranged on the drive column 53 and fits against the inner wall of the connecting part 21, so that the foldable rotor 2 is transformed from a folded state that fits the vehicle body 1 to a linear state; the rotating disk 25 is started, and the foldable rotor 2 is unfolded to an angle of 60°-120° with the direction of the vehicle body 1, and the lift wing panel 22 is transformed from a retracted state to an extended state, and the tail wing 6 is raised under the action of the elevator and extends out of the vehicle body 1, and the vehicle body 1 moves. At the same time, the propeller 31 is transformed from a stopped state to a running state. During the movement of the vehicle body 1, the lift wing panel 22 on the foldable rotor 2 rotates under the action of the airflow, providing lifting force to achieve take-off.

[0031] In the flight state, the propeller 31 is in operation, the tail wing 6 is outside the vehicle body 1 ; the foldable rotor 2 is in a linear state, and the foldable rotor 2 is at an angle of 60°-120° to the vehicle body 1 .

[0032] When the vehicle body 1 is in the landing state, the propeller 31 is changed from the running state to the stopping state. After the vehicle body 1 touches the ground and stops, the rotating disk 25 is started to drive the foldable rotor 2 to fold and rotate, so that the foldable rotor 2 is parallel to the direction of the vehicle body 1. At the same time, the lift wing 22 is changed from the extended state to the retracted state, the direction of the lift wing 22 is adjusted to be consistent with the direction of the vehicle body fixing groove 11, and the winch 23 is started to loosen the connecting wire rope 231. Under the action of the spring, the active wedge 244 disengages from the passive wedge 243, so that the clamping rod 241 moves away from the fixing clamping ring 245, so that each connecting part 21 is separated and set in the vehicle body fixing groove 11 of the vehicle body 1. After the buffer plate 42 is subjected to the pressure of the connecting part 21, the top column 43 squeezes the clamping plate 44, so that the two clamping plates 44 clamp the connecting part 21, and the positioning ball head plunger 45 is stuck in the positioning groove 212, so that the foldable rotor 2 is converted from the linear state to the folded state that fits the vehicle body 1.

[0033] After the vehicle body 1 takes off, the vehicle body driving mechanism stops running, and the propulsion driving device drives the propeller 31 to run. When in the driving state, the vehicle body driving mechanism runs to achieve front-wheel drive.

[0034] Example 2 The difference between this embodiment and embodiment 1 is that the vehicle body driving mechanism of this embodiment is four-wheel drive, and the propeller 31 is connected to the rear drive mechanism through a clutch mechanism; Figure 7 As shown, the clutch mechanism includes a conversion telescopic cylinder 38, and the output end of the conversion telescopic cylinder 38 is sequentially provided with a propulsion driving bevel gear 37 and a travel driving bevel gear 39. The propeller's rotating drive shaft 32 is meshed with the second bevel gear 35 through the first bevel gear 33. The second bevel gear 35 is installed at one end of the propulsion transmission shaft 34, and the other end of the propulsion transmission shaft 34 is installed with a meshing bevel gear 36. The meshing bevel gear 36 is arranged opposite to the propulsion driving bevel gear 37, and the travel driving bevel gear 39 is arranged opposite to the differential.

[0035] The difference in working method is as follows: after the vehicle body 1 takes off, the front drive part of the vehicle body drive mechanism stops running, and the rear drive part of the vehicle body drive mechanism continues to drive the propeller to run. When in the driving state, the vehicle body drive mechanism runs in four-wheel drive mode; The vehicle body drive mechanism and the propeller 31 are separated and engaged by controlling the extension and contraction of the conversion telescopic cylinder 38 , and the vehicle body drive mechanism and the vehicle body differential are engaged and separated.

[0036] 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 the same. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solutions of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.

At the same time, the lift wing panel changes from the extended state to the retracted state, and the direction of the lift wing panel is adjusted to be consistent with the direction of the vehicle body fixing groove. The winch is started to loosen the connecting wire rope. Under the action of the spring, the active wedge block disengages from the passive wedge block, so that the clamping rod moves away from the fixed clamping ring, so that the various connecting parts are separated and set in the vehicle body fixing groove. After the buffer plate is subjected to the pressure of the connecting part, the top column squeezes the clamping plate, so that the two clamping plates clamp the connecting part, and the positioning ball head plunger is stuck in the positioning groove, so that the foldable rotor is converted from a linear state to a folding state that fits the vehicle body.

10. The operating method of a foldable twin-rotor aircraft according to claim 9, characterized in that: When the vehicle body drive mechanism is front-wheel drive, the vehicle body drive mechanism stops running after the vehicle body takes off, and the propulsion drive device drives the propeller to run. When in the driving state, the vehicle body drive mechanism runs to achieve front-wheel drive driving; When the vehicle body drive mechanism is a four-wheel drive, after the vehicle body takes off, the front drive part of the vehicle body drive mechanism stops running, and the rear drive part of the vehicle body drive mechanism continues to drive the propeller to run. When in the driving state, the vehicle body drive mechanism runs in a four-wheel drive mode; The separation and engagement of the vehicle body drive mechanism and the propeller, as well as the engagement and separation of the vehicle body drive mechanism and the vehicle body differential are achieved by controlling the extension and contraction of the conversion telescopic cylinder.
