Description

Technical Field

[0001] The invention relates to an aircraft, an unmanned aerial propulsion device, an unmanned aerial vehicle, and a radio-controlled powered paraglider, and in particular to a detachable portable wing parachute canopy power propulsion device and a use method thereof. Background Art

[0002] The existing powered paraglider consists of an umbrella structure (wing), umbrella lines, a driving unit and a control unit (hereinafter referred to as a driving control unit). The umbrella structure is made of cloth and connected to the umbrella line, and the umbrella line is connected to the driving control unit. The driving control unit consists of a motor, a control device, a communication module, a battery, etc.

[0003] Powered paragliders have the following advantages: they are equipped with electric motors to operate and have a longer time in the air; their umbrella-like structure can act as a parachute, and compared to drones, they have a greater range of load capacity; and in an emergency situation where the drive control unit does not work, they will not fall at a free fall speed, so the possibility of damage to the fuselage is small.

[0004] However, existing powered paragliders have the following disadvantages: (1) Since the cloth umbrella-like structure may be folded in crosswinds and strong winds and cannot maintain the shape of the wings, it may fall or become uncontrollable. (2) The umbrella-like structure is connected to the drive control unit by a flexible umbrella line, and the umbrella-like structure cannot be located at the upper end of the drive control unit. This connection method makes it difficult to take off. (3) Traditional powered wing paragliders install the propeller at the load, and the driving controller pulls the traditional parachute rope to turn in the air, which has a certain response lag in control. (4) The rope can easily get entangled with the drive motor or propeller, thereby damaging the umbrella-like structure, and the maintenance and manufacturing costs are high. Therefore, it is very necessary to design a universal, portable, and detachable wing parachute canopy propulsion power device. Summary of the invention

[0005] Purpose of the invention: In view of the problems existing in the above-mentioned background technology, the present invention provides a detachable portable paraglider power propulsion device and a method of using the same.

[0006] Technical solution: To achieve the above purpose, the technical solution adopted by the present invention is:

[0007] A detachable portable parafoil power propulsion device includes two symmetrical propulsion units, characterized in that the propulsion units include a bottom guide plate, a top cover plate, a jet propeller, a motor, a propeller and a locking structure:

[0008] The bottom guide plate comprises a cylindrical connecting rod, two bottom guide plate transverse connecting pieces, a transverse umbrella-like structure frame, three guide plates, and front and rear locking connecting pieces of the bottom guide plate; wherein the cylindrical connecting rod is connected to the two bottom guide plate transverse connecting pieces, the two bottom guide plate transverse connecting pieces are connected to the transverse umbrella-like structure frame, the three guide plates are connected to the transverse umbrella-like structure frame, and the front and rear locking connecting pieces of the bottom guide plate are connected to the transverse umbrella-like structure frame;

[0009] The top cover plate includes a cover plate body, two top cover plate transverse connectors, and front and rear top cover plate lock connectors; wherein the two top cover plate transverse connectors are connected to the cover plate body, and the two top cover plate transverse connectors are connected to the cylindrical connecting rod;

[0010] The jet propeller comprises a shell, one side of which is connected to the cylindrical connecting rod, and the inside of the shell is provided with an air inlet, an air inlet duct, a propeller, a motor, a dust screen, an air compression chamber, and an air outlet in sequence from front to back: wherein the propeller is connected to the motor, and the motor is connected to a buckle on the dust screen;

[0011] The locking structure includes four U-shaped locking bodies, which are respectively located on the front and back of the umbrella power propulsion device, and fix the top cover plate and the bottom guide plate by connecting two bottom guide plate transverse connectors and two top cover plate transverse connectors in series.

[0012] A method for using a detachable portable paraglider power propulsion device comprises the following specific steps:

[0013] Step S1, inserting the circular connecting rod of the bottom guide plate into the auxiliary mounting hole on the jet thruster housing, and connecting two bottom guide plate transverse connecting pieces to the bottom guide plate and the circular connecting rod respectively;

[0014] Step S2, connecting the two top cover plate transverse connectors to the top cover plate and the circular connecting rod respectively, and fixing the motor and the propeller at the buckle of the dustproof net in the air inlet of the jet propulsion device;

[0015] Step S3, insert the parafoil between the top cover plate and the bottom guide plate, and connect the locking structure; as the motor starts, the parafoil is unfolded, and the two motors are driven simultaneously to realize the rise and advance of the parafoil, and the angle of the parafoil is changed by changing the driving speed of the single-side motor.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1) The device adopts a detachable and portable structure. Under the premise of ensuring that the parafoil canopy is not damaged, it is suitable for small and medium-sized powered parafoils of various specifications and sizes that take off from the ground; the overall design of the device is simple, which is easier to process in kind and has a low cost; the entire device can be made of composite materials, which is lighter and also ensures a certain structural strength. 2) The device is installed on both sides of the parafoil canopy. The symmetrical structural design ensures that the center of gravity of the parafoil canopy is always centered. During the flight, the two ends of the canopy can be regarded as rigid bodies, so that the shape of the wing can be maintained in crosswinds and strong winds, which improves the situation that the traditional flexible material canopy may fall or be out of control.

[0018] 3) Traditional powered paragliders install propellers at the load position. When landing, the parachute ropes are prone to collision with the drive motor or propeller, causing entanglement and damage to the parachute structure, resulting in high maintenance and manufacturing costs. This device uses an independent connection with the parachute surface and an embedded propeller structure to eliminate damage to the parachute ropes from the source, thereby reducing costs.

[0019] 4) After repeated use, traditional powered paragliders will experience varying degrees of wear and tear, resulting in a reduction in service life. The power propulsion device of the present invention adopts a split structure, and components in the power propulsion device can be replaced according to the degree of wear of the components, thereby ensuring the service life of the power propulsion device.

DETAILED DESCRIPTION

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0029] In the drawings, components are enlarged for clarity.

[0030] A detachable portable paraglider power propulsion device comprises a bottom guide plate, a top cover plate, a jet propeller and a locking structure.

[0031] The bottom deflector includes a cylindrical connecting rod, two transverse connecting pieces, a transverse umbrella-like structural frame, three fin-shaped deflectors, and front and rear locking connecting pieces. The cylindrical connecting rod is combined with the connecting piece, the transverse connecting piece is combined with the transverse umbrella-like structural frame, the fin-shaped deflector is combined with the transverse umbrella-like structural frame, and the locking connecting piece is combined with the transverse umbrella-like structural frame;

[0032] The top cover plate includes a cover plate body, two transverse connectors, and front and rear locking connectors. The two transverse connectors are combined with the cover plate body and then combined with the cylindrical connecting rod part, so that the top cover plate and the bottom guide plate form an openable hinge structure, through which the parafoil canopy can be inserted into the structure and the lock can be fastened, so that the propulsion auxiliary device body is connected to the parafoil.

[0033] The jet propeller comprises a cylindrical main body, the interior of which is composed of an air inlet, an air inlet duct, a propeller, a motor, a dust screen, an air compression chamber, and an air outlet from front to back, wherein the propeller is connected to the motor, and the motor is connected to the buckle on the dust screen.

[0034] The lock structure includes four pairs of lock connectors on both sides of the umbrella, and four U-shaped lock bodies. The two pairs of lock connectors on one side of the umbrella are respectively fixed to the top cover plate and the bottom guide plate, and the U-shaped lock body itself is combined with the lock connector fixed on the bottom guide plate to form a coaxial rotation connection. When in use, it is buckled into the lock connector fixed on the top cover plate. The above lock structure is located on both sides, with a total of four pairs.

[0035] The above-mentioned detachable portable parafoil propulsion device is composed of two pairs of parafoil surfaces, which are located on the parafoil surfaces on both sides of the parafoil to form a symmetrical structure. When the motor starts to unfold the parafoil surface, the two motors are driven at the same time to realize the parafoil's rise and advance, and the angle of the parafoil can be changed by changing the driving speed of the motor on one side.

[0036] Furthermore, it also includes a drive controller, a jet power structure, and a hidden propeller design, which improves safety while ensuring power.

[0037] Furthermore, compared with the traditional powered parafoil that installs the propeller at the load, this structure installs the power device on both sides of the parafoil, which greatly reduces the relative rotation between the parafoil and the load, and reduces the response lag of the parafoil to the control.

[0038] Furthermore, the introduction of the fin-type guide plate can greatly reduce the influence of the vortex at the tail of the umbrella, reduce the apparent mass of the umbrella, and reduce the nonlinearity of the apparent mass.

[0039] Furthermore, as a detachable portable paraglider power propulsion device of the present invention, it is characterized in that the mounting holes of the bottom guide plate and the top cover plate are provided with a 60° slide groove, which allows the device to rotate 60°. The detachable structure can also be adapted to paragliders of certain models, and has a certain universality.

[0040] A method for using the above-mentioned parafoil propulsion device comprises the following steps:

[0041] Step S1, inserting the circular connecting rod of the bottom guide plate into the auxiliary mounting hole of the jet propulsion system, and connecting two transverse connecting pieces to the bottom guide plate and the circular connecting rod respectively;

[0042] Step S2, connecting the two transverse connecting members to the top cover plate and the circular connecting rod respectively, and fixing the motor and the propeller to the dust screen buckle in the air inlet of the jet propulsion device;

[0043] Step S3, insert the parafoil between the top cover plate and the bottom guide plate, and fasten the lock device. As the motor starts to unfold the parafoil, the two motors are driven simultaneously to realize the rise and advance of the parafoil, and the angle of the parafoil is changed by changing the driving speed of the single-side motor.

[0044] The present invention provides a detachable portable paraglider power propulsion device, the specific structure of which is as follows: Figure 1 As shown, it consists of a bottom guide plate, a top cover plate, a jet propeller and a locking structure.

[0045] The bottom guide plate includes a cylindrical connecting rod, two transverse connecting pieces, a transverse umbrella-like structural frame, three fin-shaped guide plates, and front and rear locking connectors. The cylindrical connecting rod is combined with the connecting piece to ensure the stability and firmness of the guide plate, and the transverse connecting piece is combined with the transverse umbrella-like structural frame to form a whole. The transverse umbrella-like structural frame is the skeleton of the guide plate and provides a stable support structure for the guide plate. The fin-shaped guide plate is combined with the transverse umbrella-like structural frame to change the flow direction and flow rate of the airflow. The presence of the fin-shaped guide plate can effectively guide the airflow, so that it flows close to the surface of the guide plate, reduce the turbulence and resistance of the airflow, and improve the diversion effect. The locking connector is combined with the transverse umbrella-like structural frame. The above components cooperate with each other to form a stable and firm bottom guide plate structure, which provides important support for the normal operation of the entire device.

[0046] The top cover plate is composed of a cover plate body, two transverse connectors, and front and rear lock connectors. The cover plate body has a load-bearing function and can withstand pressure and vibration from the external environment. After the cover plate body is combined with the two transverse connectors, it is combined with the cylindrical connecting rod in the bottom guide plate to form an openable hinge structure. Through this structure, the parafoil canopy can be inserted into the structure and the lock can be fastened to achieve the connection between the propulsion auxiliary device body and the parafoil, which is a key part of the device function.

[0047] The jet thruster includes a cylindrical body, which is the main supporting structure of the jet thruster and accommodates other components. The interior of the cylindrical body is composed of an air inlet, an air inlet duct, a propeller, a motor, a dust screen, an air compression chamber, and an air outlet from front to back. The propeller is connected to the motor, and the motor is connected to the buckle on the dust screen. These components cooperate with each other to compress and discharge the air to generate thrust.

[0048] The locking structure is a device for connecting the umbrella surface, including four pairs of locking connections on both sides of the umbrella surface.

[0049] Connectors, four U-shaped locking bodies. Two pairs of locking connectors on one side of the umbrella are fixed to the top cover plate and the bottom guide plate respectively. The U-shaped locking body itself is combined with the locking connector fixed on the bottom guide plate to form a coaxial rotation mechanism, which is buckled into the locking connector fixed on the top cover plate when in use. The locking structure is located on both sides, front and back, with a total of four pairs. In actual use, when the umbrella needs to be connected to the top cover plate, the U-shaped locking body will be buckled into the locking connector fixed on the top cover plate. This structure can ensure a firm connection between the umbrella and the top cover plate, while allowing it to be rotated and adjusted when needed.

[0050] The above-mentioned features form a portable, detachable parafoil power propulsion device, which consists of two devices, located on the parafoil on both sides of the parafoil, forming a symmetrical structure. This design allows the motor to be evenly distributed throughout the parafoil, thereby improving the stability and controllability of the parafoil in the air. At the same time, it makes the parafoil more stable and flexible in the air, and is also convenient for disassembly and replacement. Driven by the motor, the parafoil can be controlled in terms of rise, advance and angle, and precise control of flight can be achieved.

[0051] like Figure 2 As shown, the specific method of using the above-mentioned wing parachute canopy power propulsion device is as follows:

[0052] Step S1, inserting the circular connecting rod of the bottom guide plate into the auxiliary mounting hole of the jet propulsion system, and connecting two transverse connecting pieces to the bottom guide plate and the circular connecting rod respectively;

[0053] Step S2, connecting the two transverse connecting members to the top cover plate and the circular connecting rod respectively, and fixing the motor and the propeller to the dust screen buckle in the air inlet of the jet propulsion device;

[0054] Step S3, insert the parafoil between the top cover plate and the bottom guide plate, and fasten the lock device. As the motor starts to unfold the parafoil, the two motors are driven simultaneously to realize the rise and advance of the parafoil, and the angle of the parafoil is changed by changing the driving speed of the single-side motor.

[0055] The cross-section of the jet propulsion system is shown in Figure 3 The jet propulsion system has a reasonable structure design. Air flows in from the air inlet, flows into the dust screen through the air inlet duct, and the propeller generates power under the drive of the motor, sending the air into the conical air compression chamber for compression, and finally flows out from the air outlet. The whole set of equipment conforms to a certain aerodynamic structure design.

[0056] The present invention also includes the ability to further adapt different types of bottom guide plates and top cover plate structures according to the sizes of different wing parachute canopies; a signal acquisition circuit board can also be embedded in the bottom guide plates and top cover plate structures to collect data on changes in the canopy during the operation of the wing parachute.

[0057] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
