Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary only for explaining the present application and are not to be construed as limiting the present application.

The following disclosure provides many different embodiments or examples for implementing different features of the application. To simplify the disclosure of the present application, specific example components and arrangements are described below. Of course, they are merely examples and are not intended to limit the present application. Further, the present application may repeat reference numerals and/or reference letters in the various examples for simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or arrangements discussed.

Referring to fig. 1, an embodiment of the present application provides a flying device 200, where the flying device 200 may be a flying car, a flying backpack, an unmanned aerial vehicle, and the like, the flying device 200 is mounted with a parachute apparatus 100, and the parachute apparatus 100 may be disposed on the top of the flying device 200 for safe landing of the flying device 200. The following description will be given taking the flying device 200 as an example of a flying car:

referring to fig. 2 and 3, the parachute apparatus 100 includes a parachute bay 110, a parachute pack 120, a parachute throwing mechanism 130 and a controller 140, the parachute pack 120 is accommodated in the parachute bay 110, and the parachute throwing mechanism 130 is used for pulling the parachute pack 120 out of the parachute bay 110, so that the parachute pack 120 is opened in the sky. When the flying device 200 needs to be dropped, for example, when the flying device 200 malfunctions, the controller 140 of the parachute apparatus 100 controls the parachute throwing mechanism 130 to pull the parachute package 120 out of the parachute bay 110 in response to the parachute opening instruction, so that the parachute of the parachute package 120 is opened in the air. The parachute is a deployable aerodynamic speed reducer that is inflated and deployed with respect to the movement of air by using the principle of air resistance, and slows down the falling speed of the flying device 200 by means of the air resistance, so that the flying device 200 falls stably and safely at a low falling speed.

With continued reference to fig. 2 and 3, the umbrella chamber 110 includes a chamber body 111 and a cap 112, the chamber body 111 is provided with an umbrella outlet 1111, and the cap 112 is provided with the umbrella outlet 1111. In the present embodiment, the parachute bay main body 111 may have a hollow cylindrical structure, for example, a cylindrical structure having a circular cylindrical shape, a rectangular cylindrical shape, a rhombic cylindrical shape, or another shape, the parachute bay main body 111 is used to house the parachute pack 120, and the parachute in the parachute pack 120 disposed in the parachute bay main body 111 is in a collapsed state.

When the cap 112 receives the separating force from the parachute-throwing mechanism 130, the cap 112 can be separated from the parachute outlet 1111 in a direction away from the parachute outlet 1111 and rapidly pull out the parachute pack 120 from the parachute bay main body 111, enabling the parachute of the parachute pack 120 to be opened. The outer surface of the cap 112 is streamlined so that its resistance to air can be reduced. As an example, the outer surface of the cap 112 may be a cambered surface, such as a hemispherical surface or a conical surface, so that when the cap 112 is separated from the parachute outlet 1111 by a separating force during the parachute opening process of the parachute apparatus 100, the resistance generated between the cap 112 and the air is small, which can ensure that the cap 112 has a large separation speed, so that the cap 112 can rapidly pull the parachute pack 120 out of the parachute bay main body 111, thereby achieving the rapid parachute opening of the parachute pack 120.

In this embodiment, the parachute device 100 may further include a protection cabin 113, the parachute cabin 110 is disposed in the protection cabin 113, the cap 112 is movably covered on an outlet of the protection cabin 113 and covers the parachute outlet 1111 of the parachute cabin main body 111, and the cap 112 and the protection cabin 113 together form a part of an appearance surface of the parachute device 100. When the cap 112 is subjected to the separating force, the cap 112 is directly separated from the protection cabin 113. In this embodiment, the protection cabin 113 may be fixedly connected to the umbrella cabin main body 111, the protection cabin 113 is provided with a connection portion 1131 for connecting with the flight device 200, and the connection portion 1131 may be a connection structure such as a thread structure and a buckle. Illustratively, the protection cabin 113 may have a substantially cylindrical structure, the inner space of the protection cabin 113 may be adapted to the structure of the umbrella cabin 110, and the protection cabin 113 may be detachably connected to the umbrella cabin 110. By disposing the umbrella bay 110 in the protection bay 113, the umbrella bay body 111 and the electronic devices (e.g., a battery, a control board, etc.) disposed on the umbrella bay 110 can be protected from damage.

Referring to fig. 3 and 4, the parachute bag 120 is accommodated in the parachute bay main body 111, and one end of the parachute bag 120 is connected to the cap 112 through the first parachute cord 151 and the other end is connected to the parachute bay main body 111 through the second parachute cord 152. Specifically, in the present embodiment, the parachute pack 120 includes a guide parachute 121 and a main parachute 122, the main parachute 122 is connected to the parachute bay body 111 by a second parachute cord 152, the guide parachute 121 is connected to the top of the main parachute 122 by a first parachute cord 151, and the cap 112 is connected to the top of the guide parachute 121 by a third parachute cord 153.

In the present embodiment, the number of the first umbrella strings 151, the second umbrella strings 152, and the third umbrella strings 153 is plural. Specifically, a plurality of first umbrella strings 151 are disposed at intervals along the edge of the guide umbrella 121, one end of each first umbrella string 151 is connected to the edge of the guide umbrella 121, and the other end is connected to the top of the main umbrella 122, and the plurality of first umbrella strings 151 are located in substantially the same annular region. A plurality of second umbrella strings 152 are disposed at intervals along the edge of the main umbrella 122, one end of each second umbrella string 152 is connected to the edge of the main umbrella 122, the other end is connected to the umbrella cabin body 111, and the plurality of second umbrella strings 152 are substantially located in the same annular region. Specifically, the other end of each second umbrella rope 152 may be connected to the umbrella cabin body 111 through a connection structure, and may be close to each other. When guide umbrella 121 and main umbrella 122 are in the normal open state, the outer diameter of main umbrella 122 is larger than the outer diameter of guide umbrella 121, for example, the outer diameter of main umbrella 122 is 2 times or more larger than the outer diameter of guide umbrella 121. Parachute device 100 is at the parachute-opening in-process, and cap 112 pulls out main umbrella 122 through guide umbrella 121, because the external diameter size of guide umbrella 121 is less than the external diameter size of main umbrella 122, the parachute-opening time of guide umbrella 121 is shorter, can open the umbrella fast, guide umbrella 121 provides the power of opening for main umbrella 122, and simultaneously, guide umbrella 121 can also play the effect of buffering, prevents that the initial velocity of flight device 200 when descending is too fast.

The controller 140 is communicatively connected to the parachute mechanism 130, and the controller 140 is configured to control the parachute mechanism 130 to drive the cap 112 away from the outlet 1111 in response to an parachute opening instruction to pull the parachute package 120 out of the pod body 111. The controller 140 may be mounted to the canopy body 111.

In this embodiment, the parachute apparatus 100 further includes a power module 142 and a communication module 143 coupled to the controller 140, the communication module 143 is used for communicating with the flying device 200, the power module 142 is electrically connected to the communication module 143 and the controller 140, and the power module 142 is installed on the parachute bay main body 111.

Exemplarily, the number of the power modules 142 may be two, the two power modules 142 are respectively disposed on two sides of the parachute bay main body 111 and are approximately symmetrically disposed with respect to the parachute bay main body 111, the power modules 142 may be installed between the parachute bay main body 111 and the protection bay 113, a space between the parachute bay main body 111 and the protection bay 113 may be effectively utilized, it is avoided that heat generated by the power modules 142 is concentrated to cause an over-high temperature, meanwhile, it is ensured that the two sides of the parachute apparatus 100 are uniformly stressed, and it is avoided that the opposite sides of the parachute apparatus 100 are unevenly stressed to tilt in the landing process.

Further, the controller 140 may be disposed between two power modules 142, the two power modules 142 being symmetrically disposed about the controller 140. The controller 140 may receive a control command sent by the flying device 200 through the communication module 143, and when the flying device 200 is normal, the control command of the flying device 200 may be prior to the control command of the controller 140, that is, the control command of the flying device 200 may directly control the working state of the parachute apparatus 100.

In some embodiments, the power module 142 and the controller 140 can be disposed on opposite sides of the canopy body 111, such that the power module 142 and the controller 140 can be separated from each other, thereby preventing the power module 142 and the controller 140 from concentrating heat and causing excessive temperature

Referring to fig. 4 and 5, the parachute opening mechanism 130 includes first and second

parachute opening devices

131 and 132 connected to the nacelle body 111, and the first and second

parachute opening devices

131 and 132 are respectively used to apply separating forces to both sides of the cap 112. The controller 140 of the parachute apparatus 100 controls the first and

second parachute ejectors

131 and 132 to open in response to the parachute opening command, and when the first and

second parachute ejectors

131 and 132 are opened, the first and

second parachute ejectors

131 and 132 respectively apply separating forces to both sides of the cap 112, and the direction of the application of the separating forces may substantially coincide with the axial direction of the parachute outlet 111. The cap 112 is separated from the parachute outlet 1111 to rapidly pull out the parachute bag 120, so that the parachute of the parachute bag 120 is opened, and when one of the parachute bags fails, the parachute throwing mechanism 130 can still finish the parachute opening of the parachute bag 120, thereby improving the safety. The amount of separation force applied by each of the first and

second umbrella ejectors

131 and 132 to the cap 112 may be substantially uniform.

Specifically, in the present embodiment, the first and

second parachute ejectors

131 and 132 may be a kind of initiating explosive device, and the interiors of the ejectors are filled with gunpowder and fuze, and have piston columns. When the fuse is electrified to ignite the gunpowder, the piston column generates impact force on the separation structure of the parachute thrower under the action of explosive impact, the impact force enables the separation structure of the parachute thrower to break, the parachute thrower generates larger impact force towards the cover cap 112, the cover cap 112 generates accelerated motion under the action of impact of the parachute thrower, so that the separation force is rapidly separated from the parachute bay main body 111, the cover cap 112 pulls out the guide parachute 121, the guide parachute 121 is opened in the air, and the first-stage deceleration of the parachute device 100 is realized; the guide parachute 121 pulls out the main parachute 122, and the main parachute 122 opens in the air, thereby realizing the secondary deceleration of the parachute apparatus 100.

In some embodiments, the first and

second ejectors

131 and 132 may also be automatic ejectors, which may use compressed air or hydraulic pressure as an ejection power to rapidly eject the cap 112 from the canopy body 111.

In some embodiments, as shown in fig. 5, the first and

second umbrella ejectors

131 and 132 are respectively disposed at opposite sides of the umbrella outlet 1111, and the controller 140 is configured to control the first and

second umbrella ejectors

131 and 132 to be opened simultaneously in response to an umbrella opening command. Illustratively, the first and

second parachute ejectors

131 and 132 may be disposed outside the nacelle body 111 and may be disposed substantially symmetrically about a radial direction of the outlet 1111.

In the process of falling the parachute device 100, the controller 140 can control the first and

second parachute throwers

131 and 132 to open simultaneously, so as to simultaneously act on the separating force to both sides of the cap 112, because both sides of the cap 112 simultaneously receive the separating force, both sides of the cap 112 can be separated from the parachute outlet 1111 substantially towards the direction that the cap 112 is far away from the parachute outlet 1111 simultaneously, the cap 112 can pull the guide parachute 121 open uniformly through the first parachute cord 151, ensuring the complete parachute opening of the guide parachute 121, when one of them breaks down, the parachute opening mechanism 130 can still complete the parachute opening of the parachute pack 120, and the safety is improved. Further, in some embodiments, the parachute throwing mechanism 130 can include a plurality of parachutors, which can be spaced around the exit 1111.

In some embodiments, as shown in fig. 4, the parachute apparatus 100 includes a connection mechanism 170 and a state detection sensor 160, the state detection sensor 160 is disposed on at least one of the canopy of the parachute pack 120 and the second parachute cord 152, the connection mechanism 170 is connected to the parachute bay main body 111, the connection mechanism 170 includes a parachute tray 171 and an adjustment member 172, the adjustment member 172 is connected to the parachute tray 171, the parachute tray 171 may be of a substantially disc-sheet structure, the parachute tray 171 is connected between the adjustment member 172 and the second parachute cord 152, specifically, the other end of the second parachute cord 152, which is far away from the main parachute 122, is connected to the parachute tray 171, and the controller 140 is configured to control the adjustment member 172 to tighten the second parachute cord 152 when a detection signal of the state detection sensor 160 corresponds to a preset change. When the canopy of the main umbrella 122 breathes, the adjusting assembly 172 may tighten the second umbrella string 152 to apply an inward pulling force to the outer circumference of the umbrella bag 120, and the outer circumference of the main umbrella 122 may be appropriately closed, thereby suppressing the breathing of the main umbrella 122, so that the parachute apparatus 100 may be smoothly dropped.

The 'breathing phenomenon' means that when the parachute is in a landing state, the canopy of the parachute is filled with gas, the canopy still continues to expand outwards, the surface of the canopy is tensioned, the surface tension of the canopy is increased, the outer diameter of the canopy continues to increase, the canopy rope connected with the canopy is tensioned, and therefore the tension of the canopy rope connected with the canopy is also increased; then the umbrella is contracted, the outer diameter of the umbrella is reduced, the surface of the umbrella is contracted, the surface tension is reduced, the umbrella rope connected with the umbrella is loosened, and the tension of the umbrella rope connected with the umbrella is reduced. In the whole process, the canopy is repeatedly expanded and contracted. The main reason for breathing phenomenon of the canopy is usually caused by the problem of flexible material of the canopy, and as the flexible material cannot keep the shape of the canopy unchanged like a rigid material, the canopy usually fluctuates in the periodic repeated fluctuation period, however, the breathing phenomenon can cause the "surge" or resonance phenomenon of the canopy.

In some embodiments, the condition detecting sensor 160 may include at least one of a flexibility sensor, a tension sensor 161, and a vibration sensor 162. Illustratively, the flexible sensor may comprise a piezoresistive flexible pressure sensor, a capacitive flexible pressure sensor, or a piezoelectric flexible pressure sensor, for example, which may be disposed on a surface of a canopy. When the flexible sensor deforms, the deformation quantity is different, the output voltage of the flexible sensor is also different, and the output voltage increases along with the increase of the deformation quantity, wherein the deformation can comprise multiple types, for example, the flexible sensing device can be bent or stretched, so that bending deformation or stretching deformation occurs; the flexible sensor outputs voltage signals under the action of external force, when the bending degree of the surface of the canopy or the umbrella rope is larger, the voltage signals output by the flexible sensor are larger, and when the change of the detected voltage signals accords with the preset voltage change, the canopy is determined to generate a breathing phenomenon; the tension sensor 161 may be a strain gauge type, in which a tension strain gauge and a compression strain gauge are connected together in a bridge manner, and a resistance value of the strain gauge changes when external pressure is applied, and when a bending degree of the surface of the canopy or the umbrella cord is larger, the resistance value is larger, and when a detected resistance value meets a preset resistance change, it is determined that the canopy generates a breathing phenomenon; the vibration sensor 162 may include an eddy current type vibration sensor 162, an inductive type vibration sensor 162, a capacitive type vibration sensor 162, a piezoelectric type vibration sensor 162, or a resistance strain type vibration sensor 162, when the vibration sensor 162 performs vibration measurement on the canopy, the vibration sensor can convert the vibration parameter of the canopy into an electrical parameter signal (output voltage or output current, etc.), when the vibration quantity is large, the output voltage or output current is larger, and when it is detected that the change of the output voltage corresponds to the change of the preset voltage, or the change of the output current corresponds to the change of the preset current, it is determined that the canopy generates a breathing phenomenon.

In some embodiments, as shown in fig. 4 and 6, the adjustment assembly 172 may include a drive portion 1721 and a telescoping rod 1722. The driving part 1721 is connected with the umbrella disc 171 through an expansion rod 1722, and the driving part 1721 drives the expansion rod 1722 to expand and contract. The state detecting sensor 160 may include a tension sensor 161, and the tension sensor 161 is disposed at the second parachute cord 152 or the canopy, and for example, the tension sensor 161 may be disposed at a canopy surface of the main parachute 122 for detecting a tension of the surface of the main parachute 122. When the tension sensor 161 detects that the tension value is changed according to the preset tension value, the adjusting assembly 172 may tighten the second umbrella rope 152, and the second umbrella rope 152 applies an inward pulling force to the outer circumference of the umbrella bag 120, so as to suppress the breathing phenomenon of the main umbrella 122.

Illustratively, in the process of falling, when it is detected that the tension value of the main parachute 122 is increased and then decreased, and meets the preset variation rule, the parachute device 100 determines that the canopy breathes. When the canopy breathes, the outer diameter of the canopy is continuously increased, the surface of the canopy is in a more tensioned state, the surface tension of the canopy is increased, and meanwhile, the canopy tightens the second umbrella cord 152 more, so that the tension value of the second umbrella cord 152 is also increased, when the canopy, which breathes, contracts, the surface tension value of the canopy is reduced, and at the same time, the tightened second umbrella cord 152 is released, so that the second umbrella cord 152 is tightened, and the tension value of the second umbrella cord 152 is also reduced, so that when the canopy breathes, the tension values of the canopy and the second umbrella cord 152 are substantially changed in a substantially same regular manner, and therefore, the tension sensor 161 can detect the change of the tension values of the canopy and the second umbrella cord 152, and when the detected tension value is increased to the value a and is reduced to the value b, the value a is greater than the value b, the controller 140 controls the driving part 1721 to shorten downwards, and the telescopic rod 1722 tightens the second umbrella cord 152 to apply the tension to the outer periphery of the umbrella 120, thereby inhibiting the breathing phenomenon.

In other embodiments, the adjustment assembly 172 may include a winding portion, the other end of the second umbrella cord 152, which is away from the main umbrella 122, is wound around the winding portion, and when the tension sensor 161 detects that the tension value changes according to the preset tension value, the controller 140 controls the winding portion to rotate in a forward direction to wind a portion of the length of the second umbrella cord 152, such that the second umbrella cord 152 is tightened, and the second umbrella cord 152 applies an inward pulling force to the outer circumference of the umbrella bag 120, such that the breathing phenomenon of the main umbrella 122 is suppressed.

As another example, the state detection sensor 160 further includes a vibration sensor 162, the vibration sensor 162 is disposed on the canopy of the parachute pack 120 or the second parachute harness 152, and when the vibration frequency detected by the vibration sensor 162 is changed according to a preset frequency, the controller 140 controls the driving part 1721 to drive the telescopic rod 1722 to be shortened. When the canopy is breathing, the canopy is regularly expanded outward and then contracted inward, and therefore, under the action of the airflow, the surface of the canopy generates regular vibration, and the vibration frequencies of the canopy and the second canopy cord 152 basically show approximately the same regular change, so that when the vibration sensor 162 detects that the vibration frequency of the canopy or the second canopy cord 152 conforms to the preset frequency change, it is determined that the canopy is breathing, and therefore, the controller 140 may control the driving portion 1721 to shorten the telescopic rod 1722 to inhibit the breathing phenomenon of the canopy.

In some embodiments, the state detection sensor 160 may further include an image sensor (not shown), the image sensor may be disposed outside the umbrella chamber main body 111, and a camera of the image sensor may be disposed toward the side where the umbrella outlet 1111 is located. When the parachute apparatus 100 is landed, the image sensor is used to acquire the outer circumferential profile of the main parachute 122 in real time, and the controller 140 determines the radius change of the outer circumferential profile of the main parachute 122 in real time according to the outer circumferential profile acquired by the image sensor in real time. When the canopy breathes, the canopy can be outwards expanded regularly and then contracts inwards, the radius of the peripheral outline of the canopy is increased and then reduced, and the change is regular. If the radius change of the outer circumference profile conforms to the preset radius change, it is determined that the canopy has a breathing phenomenon, and the controller 140 controls the driving part 1721 to shorten the telescopic rod 1722, so that the second umbrella cord 152 is tightened, and the second umbrella cord 152 applies an inward pulling force to the outer circumference of the umbrella pack 120 to suppress the breathing phenomenon of the canopy. The image sensor can accurately acquire the change of the peripheral contour of the canopy in real time, and determine whether the canopy is in a breathing state by measuring the change of the radius of the peripheral contour in real time, so that the adjusting component 172 can tighten the second canopy rope 152 in time, the breathing phenomenon of the canopy is effectively inhibited, and the stable landing of the flight device 200 is realized.

In some applications, as shown in fig. 4 and 6, the parachute apparatus 100 further comprises a height detection sensor 193, the connection mechanism 170 may comprise a mounting member 173 and a self-separating member 174, the parachute tray 171 is adapted to be connected to the flying device 200 carrying the parachute apparatus 100, and the second parachute line 152, the mounting member 173, the self-separating member 174 and the parachute tray 171 are sequentially connected. When the height detection sensor 193 detects that the height at which the parachute device 100 is located is less than or equal to the preset height, the preset height is a safe height at which the parachute device 100 is landed. The controller 140 is used to control the automatic release 174 to release the attachment 173 from its connection with the umbrella shaft 171. When the height detection sensor 193 detects that the flying device 200 is about to land, the controller 140 is used for controlling the automatic separating piece 174 to automatically separate the mounting piece 173 from the parachute tray 171, so that the parachute is separated from the flying device 200, the phenomenon that the flying device 200 is dragged by the parachute due to the body of the flying device 200 pulled by the parachute is effectively avoided, the flying device 200 can land stably, the flying device 200 is not easy to collide with the ground, and the landing safety is improved.

Illustratively, the automatic separating member 174 may be an explosion bolt, both ends of which are provided with screw coupling parts, and the mounting member 173 may be a mounting ring, which may be screw-coupled with one end of the explosion bolt, and the flying device 200 is coupled with the other end of the explosion bolt by a bolt. The explosion bolt 22 is an initiating explosive device, has a shape structure similar to a bolt, is filled with gunpowder and a fuse, and after the fuse is electrified and detonates the gunpowder, the weak position of the explosion bolt 22 is broken, so that the parachute pack 120 connected with the explosion bolt 22 is separated from the flight device 200. When the flying device 200 is about to land, the controller 140 may control the explosion bolt to be powered on for detonation, and the weak position of the explosion bolt 22 is disconnected, so that the mounting member 173 is separated from the umbrella disc 171, and after the flying device 200 lands, since the parachute is already separated from the flying device 200, the parachute does not generate drag force on the flying device 200, thereby effectively ensuring the safety of the flying device 200 when landing.

In addition, in some embodiments, the automatic separating element 174 may also be an electromagnetic locking mechanism, the electromagnetic locking mechanism may lock the mounting element 173 on the umbrella disc 171, and when the height of the parachute apparatus 100 is less than or equal to the preset height, the controller 140 may control the electromagnetic locking mechanism to release the locking of the mounting element 173, so as to achieve the rapid separation of the parachute from the flying device 200.

Further, when the flight device breaks down in the air, for example, when the power supply device and the control device of the flight device break down, the parachute device can provide electric energy for the controller through the power supply module of the parachute device, and the controller sends out a parachute opening instruction to the parachute throwing mechanism to control the parachute package to open the parachute; when the flight device descends to the preset height, the controller can also send a control instruction to the automatic separating piece to enable the automatic separating piece to be automatically separated, so that separation between the parachute and the flight device is achieved, the flight device is prevented from being dragged by the parachute, and safety is improved.
