[0061] The first shell 1, the second shell 2 and the side covers arranged at both ends of the first shell 1 can form a sealed space for storing the unfolded net 5, which has the function of waterproof and dustproof.

[0062] The cylinder 4 is rotatably arranged in the first shell 1; the unfolding net 5 is rolled up on the cylinder 4, and the other end of the unfolding net 5 is fixed to the second shell 2; when the unfolding net 5 is not in use, the unfolding net 5 is rolled up on the cylinder 4 and stored in a sealed space formed by the first shell 1, the second shell 2 and the side cover plate, which is waterproof and dustproof, can well protect the unfolding net 5, and extend the service life of the unfolding net 5.

[0063] The driving device 6 is arranged inside the cylinder 4, and the driving device 6 drives the cylinder to rotate inside the first housing 1. The motor is prevented from being exposed to the air, and is waterproof and dustproof.

[0064] One end of the extension arm 3 is fixed to the first shell 1, and the other end of the extension arm 3 is fixed to the second shell 2; in a natural state, the extension arm 3 is in an extended state, and the two sections of the extension arm 3 are at an obtuse angle to prevent the force arms from being collinear and forming mechanical self-locking; in the retracted state, the extension arm 3 is in a folded state, and the self-locking force of the driving device 6 is greater than the extension force of the extension arm 3. Under the action of the self-locking of the driving device 6 and the tension of the fabric surface of the unfolding net 5, the extension arm 3 is folded, the unfolding net 5 is retracted, and the second shell 2 is recovered to the position of the first shell 1.

[0065] The integrated test stand described in this embodiment is installed in a car for recovering drones. The first shell 1 is fixed on the car. When the drone is not recovered, the extension arm 3 is under the action of the self-locking force of the drive device 6 and the tension of the unfolding net 5 in the retracted state. The second shell 2 is spliced ​​into one with the first shell 1 to form a sealed space, and the unfolding net 5 and the cylinder 4 are protected inside the sealed space. When the drone needs to be recovered, the drive device 6 drives the rotation, driving the cylinder 4 to rotate. The self-locking force of the drive device 6 is 0. Under the action of the extension force of the extension arm 3, the other end of the extension arm 3 pushes the second shell 2 to move forward. During the forward movement of the second shell 2, the unfolding net 5 rolled on the cylinder is unfolded. The extension arm 3 unfolds the unfolding net 5 while providing the lower support force for the unfolding net 5. The unfolded unfolding net 5 can achieve the landing and recovery of the drone.

[0066] In the embodiment, the extension arm 3 is an elastic bracket.

[0067] In the embodiment, the extension arm 3 includes two support arms and an elastic member; the elastic member is arranged inside the two support arms, and when the net retracting device is unfolded, the two support arms are in a bent position, and when the unfolding net is unfolded, the elastic member provides a force to the two support arms to move the two support arms to a straight position.

[0068] The elastic member provides an extension force for the extension arm 3 .

[0069] In the embodiment, a fixing groove 41 is formed on the outer wall of the cylinder 4 , and one end of the unfolding net 5 is fixed to the fixing groove 41 .

[0070] In the embodiment, connecting pieces 42 are provided at both ends of the cylinder 4 .

[0071] In the embodiment, Figure 3 and Figure 4 As shown, the driving device 6 includes a left connecting wheel 61 , a switch assembly 62 , a motor 63 , a controller 65 and a right connecting wheel 64 .

[0072] In the embodiment, the right connecting wheel 64 is connected to the output end of the motor 63, and the outer wall of the right connecting wheel 64 is clamped on the inner wall of the cylinder 4;

[0073] Among them, the motor 63 drives the right connecting wheel 64 to rotate, and then drives the cylinder 4 to rotate. Under the action of the elastic member, the two support arms move from the bent position to the straight position, so that the second shell 2 moves away from the first shell 1, and the unfolding net 5 is electrically unfolded.

[0074] The left connecting wheel 61 is arranged on the connecting member 42 .

[0075] In the embodiment, the controller 65 includes a brake assembly 66, a reducer 67, a drive module, a filter module and a power supply module, which are used to supply power to the device and adapt to the special electromagnetic compatibility environment required for the test.

[0076] In the embodiment, the drone recovery device communicates via the vehicle-mounted CAN bus, and the controller 65 can transmit CAN signals to monitor and control the deployment, suspension, and retraction of the deployment net 5 in real time. By adding a filtering module, the vehicle-mounted electromagnetic compatibility requirements are met.

[0077] In the embodiment, the mechanical switch includes a planetary gear, one end of the planetary gear is connected to the left connecting wheel 61 , and the other end of the planetary gear is connected to the motor shaft of the motor 63 .

[0078] When the driving device 6 is used to drive the unmanned aerial vehicle recovery device to unfold, the electric transmission mode is: after receiving the CAN bus signal, the rotor of the power device rotates. The motor rotor drives the motor housing, and the right connecting wheel 64 cooperates with the barrel 4 through the clamping, and the rotational power is transmitted to the barrel 4 through the right connecting wheel 64. After the barrel 4 rotates, the self-locking force of the motor 63 becomes 0, and the extension force of the extension arm 3 serves as the main force. Under the action of the extension force, the second shell 2 moves away from the first shell 1 to realize the unfolding of the unfolding net 5. The unfolded unfolding net 5 is used to recover the unmanned aerial vehicle. At the same time, the barrel 4 controls the rotation of the planetary gear in the switch assembly 62 through the left connecting wheel 61 on the left side.

Under the action of the elastic member, the two support arms move from the bent position to the straight position, so that the second shell 2 moves away from the first shell 1, and the unfolding net 5 is manually unfolded.

[0082] Manually rotating the manual lever 7 drives the left connecting wheel 61 and the switch assembly 62 in turn, drives the planetary gear in the switch assembly 62 to rotate, drives the motor shaft to rotate, and the motor housing rotates together with the motor shaft, and drives the cylinder 4 to rotate via the right connecting wheel 64. Under the action of the extension force of the extension arm 3, the second housing 2 moves away from the first housing 1, or the second housing 2 moves close to the first housing 1, thereby driving the unfolding net 5 to unfold and retract. The manual rotation area and the electric rotation area of ​​the driving device 6 are not connected, but are both connected to the motor housing, so the electric part also rotates with the motor housing.

[0083] Embodiment 3

[0084] This embodiment provides an integrated test stand, which is based on the second embodiment, in order to better simulate the complex and changeable outdoor environment, especially in strong winds, rain and snow, to ensure that the drone can accurately land on the recovery component.

When not in use or maintenance is required, the first shell 1 can be removed from the base 8.

[0086] The capture assembly 9 includes two lifting rods 91, a capture net 92, a power device, a transmission rod, a transmission wheel and a fixing rod 93; the lower end of the lifting rod 91 is fixed on a flange 94, the center hole of the flange 94 corresponds to the through hole on the side seat, the fixing rod 93 passes from the through hole on the first side seat, the center hole of the flange 94 and another through hole on the first side seat from left to right, and then passes through the through hole on the second side seat, the center hole of the flange 94 arranged in the second side seat groove structure 81 and another through hole on the second side seat, the fixing rod 93 and the center hole of the flange 94 are interference fit, and the flange 94 rotates with the rotation of the fixing rod 93;

[0087] A power assembly is also arranged on the side wall of the side seat. When the capture assembly 9 needs to be electrically driven to rotate, the power assembly is started. The power assembly includes a power device, a transmission rod and a transmission wheel. The output end of the power device is provided with a transmission rod; one end of the fixed rod 93 is provided with a transmission wheel at a position corresponding to the transmission rod; the power device drives the transmission rod to rotate, the transmission rod drives the transmission wheel to rotate, the transmission wheel drives the fixed rod 93 to rotate, and the fixed rod 93 drives the flange 94 to drive the lifting rod 91 to reciprocate between the horizontal position and the vertical position in the groove structure 81.

[0088] A capture net 92 is provided on the two lifting rods 91. The capture net 92 is made of Kevlar fiber and can be detachably tied to the lifting rods 91 by straps; alternatively, a hook structure is provided on the lifting rods 91 to hang the capture net 92 on the lifting rods 91, so as to facilitate the disassembly, maintenance and replacement of the capture net 92.

[0089] The capture assembly 9 is used in conjunction with the deployment net 5. When the outdoor environment is relatively bad, such as encountering strong winds, heavy fog or other bad weather, the drone cannot accurately land on the deployment net 5, and the drone can fly to the capture net 92, and the capture net 92 can be used to intercept the drone.

[0090] Alternatively, in windy, rainy or snowy weather, although the UAV lands on the deployment net 5, there is also a risk of being blown away or even damaged. At this time, the power device is started, the power device drives the screw to rotate, the transmission rod drives the transmission wheel to rotate, the transmission wheel drives the fixing rod 93 to rotate, the fixing rod 93 drives the flange 94 to rotate, and the flange 94 drives the lifting rod 91 to rotate from a vertical position to a horizontal position, that is, the lifting rod 91 is located at both ends of the deployment net 5, so that the capture net 92 is covered on the upper part of the deployment net 5, thereby preventing the UAV from being blown away.

[0091] In addition, the capture net 92 can be set up as a multi-layer structure, the first layer structure is an interception rope made of Kevlar fiber, a fire-retardant coating is coated on the outside of the interception rope, and a waterproof layer is arranged on the upper part of the first layer structure. The capture net 92 covers the drone parked on the unfolding net 5, which can achieve the functions of windproof and waterproof.

[0092] In the embodiment, when the wind is strong or the rain and snow are heavy, the drone cannot dock on the deployment net 5 or cannot fly to the capture net 92. The capture net 92 is within the range of reciprocating motion between the vertical position and the horizontal position. As long as the drone is within the above range, the power device 93 drives the lifting rod 91 from the vertical position to the horizontal position, and the drone still in flight within the range is forced to land on the deployment net 5. No matter what the conditions are, the drone can be effectively recovered.

[0093] The unfolded net 5 comprises a base layer and a buffer layer, wherein the base layer is a layer woven from elastic ropes, and the buffer layer is a sponge layer arranged on the upper end surface of the base layer.

[0094] Embodiment 4

[0095] This embodiment provides an integrated test bracket, which is based on the third embodiment. Figures 6 to 10 As shown, it also includes a linkage component. When the UAV lands on the unfolded net 5, under the action of the linkage component, the capture component 9 adaptively rotates from a vertical position to a horizontal position, and the capture net 92 covers the UAV to prevent the UAV from being blown away by strong winds or damaged by bad weather.

[0096] The linkage assembly includes a trigger member 101, a first connecting rope 102, an action end 103 and a reset end 104; the trigger member 101 includes a first damping member 1011, a column 1012 and a trigger end 1013; the trigger end 1013 is arranged at the upper end of the column 1012, and the column 1012 is inserted in the first damping member 1011; a through hole is opened on the extension arm 3, the first damping member 1011 is arranged on the through hole, and the column 1012 extends through the through hole to the bottom of the extension arm 3; when the deployment net 5 is normally deployed and the drone has not landed on the deployment net 5, the trigger end 1013 is against the lower end surface of the deployment net 5, or the trigger end 1013 and the lower end surface of the deployment net 5 have a very small gap, and the vibration of the deployment net 5 caused by the drone falling on the deployment net 5 can act on the trigger end 1013.

[0097] like Figure 6 and Figure 7As shown, the action end 103 includes a rolling member 1031 and a lifting unit 1032 that are set against the flange 94; an L-shaped groove structure is provided on the lower end surface of the groove structure 81; the lifting unit 1032 includes a plate body 10321, a second damping member 10322 and a baffle, and one end of the plate body 10321 is hinged to the L-shaped groove structure; the lower end of the second damping member 10322 is set on the upper end surface of the L-shaped groove structure, and the upper end of the second damping member 10322 is set against the lower end surface of the plate body 10321; the rolling member 1031 is located on the plate body 10321 Above one end of the plate body 10321, under the support of the second damping member 10322, the other end of the plate body 10321 is slightly higher than or one end of the plate body 10321, or the height of the other end of the plate body 10321 is equal to the height of one end of the plate body 10321, so that the rolling element 1031 is maintained at the position where it is against the flange 94; the baffle is arranged at the other end of the plate body 10321, and the baffle is arranged vertically to the plate body 10321, and when the rolling element 1031 rolls from one end of the plate body 10321 to the other end, the baffle can prevent the rolling element 1031 from falling.

[0098] like Figure 8 and Fig. 9 As shown, the reset end 104 includes a second connecting rope 1041, a rotating column 1042, a driving wheel 1043, a driven wheel 1044, a transmission chain 1045 and a rotating rod 1046; the rotating column 1042 is rotatably arranged on the inner side wall of the groove structure 81, and the rotating column 1042 is located above the other end of the plate body 10321; one end of the second connecting rope 1041 is arranged on the other end of the plate body 10321, and the other end of the second connecting rope 1041 is fixed on the rotating column 1042; the groove structure 81 On the side wall, through holes are opened at positions corresponding to the fixed rod 93 and the rotating column 1042, and the fixed rod 93 and the rotating column 1042 extend through the through holes to the outside of the groove structure 81; the driving wheel 1043 and the passive wheel 1044 are both arranged on the outer side wall of the groove structure 81, and are respectively sleeved on the fixed rod 93 and the rotating column 1042; the transmission chain 1045 is meshed on the driving wheel 1043 and the passive wheel 1044; the rotating rod 1046 is arranged on the fixed rod 93.

[0099] During use, when the drone lands on the deployment net 5, the deployment net 5 is driven to vibrate, and the deployment net 5 moves downward. The lower end surface of the deployment net 5 acts on the trigger end 1013, and the trigger end 1013 drives the column 1012 to move downward, so that the first connecting rope 102 at the lower end of the column 1012 moves downward, and the other end of the first connecting rope 102 pulls the other end of the plate 10321 to move downward. The other end of the plate 10321 moves downward to form a slope, and the rolling element 1031 rolls from one end of the plate 10321 to the other end of the plate 10321. The rolling element 1031 is no longer set to resist the flange 94, and after the resisting force disappears, the flange 94 rotates in the direction of the rolling element 1031 under the action of the reaction force, so that the capture component 9 rotates from the vertical position to the horizontal position, so that after the drone lands on the deployment net 5, under the traction of the linkage component, the capture component 9 automatically falls on the deployment net 5 to prevent the drone from being blown away by strong wind and causing damage to the drone.

[0100] After use, the handle is turned, and the handle drives the fixed rod 93 to rotate, and the fixed rod 93 drives the capture assembly 9 to rotate from the horizontal position to the vertical position for the next use, or the capture assembly 9 intercepts the drone in the vertical position. When the handle drives the fixed rod 93 to rotate, the driving wheel 1043 set on the fixed rod 93 is driven to rotate, the driving wheel 1043 drives the transmission chain 1045 to rotate, the transmission chain 1045 drives the passive wheel 1044 to rotate, and the passive wheel 1044 drives the rotating column 1042 to rotate, so that the second connecting rope 1041 is wound around the winding, and the second connecting rope 1041 pulls the other end of the plate body 10321 upward, and the rolling element 1031 moves with the plate body 10321 to the position against the flange 94.

[0101] The first connecting rope 102 is detachably arranged on the lower end surface of the column 1012. When in use, if the external environment is good and the drone can accurately land on the deployment net 5, the connection between the first connecting rope 102 and the lower end surface of the column 1012 can be disconnected, that is, the transmission of the force between the trigger member 101 and the action end 103 is disconnected. When the drone lands on the deployment net 5, the capture component 9 will not automatically change from a vertical position to a horizontal position.

[0102] In this embodiment, the power device 93, the transmission rod 94 and the transmission wheel 95 are arranged on the side seat of the base 8. The specific positions of the power device 93, the transmission rod 94 and the transmission wheel 95 are not on the side wall of the same side seat as the reset end 104, so that the operation of the power device 93 and the operation of the reset end 104 do not affect each other. In actual operation, the capture component 9 can be driven by the power device 93 to reciprocate between the vertical position and the horizontal position.

[0103] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
