DETAILED DESCRIPTION

[0041] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used to explain the principles of the present invention together with the present invention.

[0042] Embodiment 1

[0043] This embodiment provides a light UAV recovery device, see Figure 1 to Figure 2 , which comprises: a main housing 1, a front housing 2, a folding arm 3, a sleeve 4, a recovery net 5 and a drum motor 6;

[0044] The main shell 1, the front shell 2 and the side covers arranged at both ends of the main shell 1 can form a sealed space for storing the recovery net 5, which has the function of waterproof and dustproof.

[0045] The sleeve 4 is rotatably arranged in the main shell 1; the recovery net 5 is rolled up on the sleeve 4, and the other end of the recovery net 5 is fixed to the front shell 2; when the recovery net 5 is not in use, the recovery net 5 is rolled up on the sleeve 4 and stored in the sealed space formed by the main shell 1, the front shell 2 and the side cover plate, which is waterproof and dustproof, can well protect the recovery net 5, and extend the service life of the recovery net 5.

[0046] The drum motor 6 is arranged inside the sleeve 4, and the drum motor 6 drives the sleeve to rotate inside the main housing 1. The motor is prevented from being exposed to the air, and is waterproof and dustproof.

[0047] One end of the folding arm 3 is fixed to the main shell 1, and the other end of the folding arm 3 is fixed to the front shell 2; in a natural state, the folding arm 3 is in an extended state, and the two sections of the folding 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 folding arm 3 is in a folded state, and the self-locking force of the drum motor 6 is greater than the stretching force of the folding arm 3. Under the action of the self-locking of the drum motor 6 and the tension of the cloth surface of the recovery net 5, the folding arm 3 is folded, the recovery net 5 is retracted, and the front shell 2 is retracted to the position of the main shell 1.

[0048] The light UAV recovery device described in this embodiment is installed in a car used for UAV recovery. The main housing 1 is fixed on the car. When the UAV is not recovered, the folding arm 3 is under the action of the self-locking force of the drum motor 6 and the pulling force of the recovery net 5 in the retracted state, and the front housing 2 is spliced ​​with the main housing 1 to form a sealed space, and the recovery net 5 and the sleeve 4 are protected inside the sealed space. When the UAV needs to be recovered, the drum motor 6 drives the sleeve 4 to rotate, and the self-locking force of the drum motor 6 is 0. Under the action of the stretching force of the folding arm 3, the other end of the folding arm 3 pushes the front housing 2 to move forward. During the forward movement of the front housing 2, the recovery net 5 rolled on the sleeve is unfolded. While the folding arm 3 unfolds the recovery net 5, it provides a lower support force for the recovery net 5. The unfolded recovery net 5 can achieve the landing and recovery of the UAV.

[0049] In the embodiment, the folding arm 3 is an elastic bracket.

[0050] In the embodiment, the folding arm 3 includes two support arms and an elastic member; the elastic member is arranged inside the two support arms, and the elastic member provides a force to the two support arms to move the two support arms from a bent position to an extended position.

[0051] The elastic member provides an extension force for the folding arm 3 .

[0052] In the embodiment, a groove 41 is formed on the outer wall of the sleeve 4 , and one end of the recovery net 5 is fixed to the groove 41 .

[0053] In the embodiment, sleeve connectors 42 are provided at both ends of the sleeve 4 .

[0054] In the embodiment, Figure 3 and Figure 4 As shown, the drum motor 6 includes a first engaging wheel 61 , a mechanical travel switch 62 , a motor 63 , a controller 65 and a second engaging wheel 64 .

[0055] In the embodiment, the second connecting wheel 64 is connected to the output end of the motor 63, and the outer wall of the second connecting wheel 64 is clamped on the inner wall of the sleeve 4;

[0056] Among them, the motor 63 drives the second connecting wheel 64 to rotate, and then drives the sleeve 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 front shell 2 moves away from the main shell 1, and the recovery net 5 is electrically unfolded.

[0057] The first engaging wheel 61 is disposed on the sleeve connector 42 .

[0058] In the embodiment, the controller 65 includes a brake module 66, a deceleration module 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.

[0059] 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 recovery net 5 in real time. By adding a filter module, the vehicle-mounted electromagnetic compatibility requirements are met.

[0060] In the embodiment, the mechanical switch comprises a planetary gear, one end of the planetary gear is connected to the first connecting wheel 61 , and the other end of the planetary gear is connected to the motor shaft of the motor 63 .

[0061] When the drum motor 6 is used to drive the drone recovery device to unfold, the electric transmission mode is: after receiving the CAN bus signal, the motor rotor is driven to rotate. The motor rotor drives the motor housing, and the second connecting wheel 64 is matched with the sleeve 4, and the rotation power is transmitted to the sleeve 4 through the second connecting wheel 64. After the sleeve 4 rotates, the self-locking force of the motor 63 becomes 0, and the extension force of the folding arm 3 is used as the main force. Under the action of the extension force, the front shell 2 moves away from the main shell 1 to realize the unfolding of the recovery net 5. The unfolded recovery net 5 is used to recover the drone. At the same time, the sleeve 4 controls the rotation of the planetary gear in the mechanical travel switch 62 through the first connecting wheel 61 on the left.

[0062] The planetary gear includes a transmission shaft, a sun gear, a planetary gear and an output shaft; the transmission shaft is connected to the output end of the first connecting wheel 61, the first connecting wheel 61 transmits power to the sun gear through the transmission shaft, the planetary gear is meshed with the sun gear and then transmitted to the planetary gear, a planetary disk is arranged outside the planetary gear, the planetary disk rotates with the planetary gear, and the planetary gear rope is provided with an output shaft. When the recovery net 5 is fully unfolded, the output shaft acts on the controller 65 accordingly, the electromagnetic relay in the controller 65 works, disconnects the circuit, and the motor rotor stops rotating.

[0063] In the embodiment, the light UAV recovery device can also be manually operated to deploy and recover the recovery net 5 in the event of a power outage.

[0064] The drum motor 6 also includes a rocker arm 7, which is arranged on the first connecting wheel 61; the rocker arm 7 is manually rotated to drive the first connecting wheel 61, the mechanical travel switch 62, the motor 63 and the second connecting wheel 64 to rotate in turn, and the second connecting wheel 64 drives the sleeve 4 to rotate. Under the action of the elastic member, the two support arms move toward the straight position, so that the front shell 2 moves away from the main shell 1, and the recovery net 5 is manually unfolded.

[0065] Manually rotating the rocker arm 7 sequentially drives the first connecting wheel 61 and the mechanical travel switch 62, drives the planetary gear in the mechanical travel switch 62 to rotate, drives the motor shaft to rotate, and the motor housing rotates together with the motor shaft, and drives the sleeve 4 to rotate via the second connecting wheel 64. Under the action of the extension force of the folding arm 3, the front housing 2 moves away from the main housing 1, or the front housing 2 moves close to the main housing 1, thereby driving the recovery net 5 to unfold and retract the cloth surface. The manual rotation area and the electric rotation area of ​​the drum motor 6 are not connected, but are both connected to the motor housing, so the electric part also rotates with the motor housing.

[0066] Embodiment 2

[0067] This embodiment provides another light UAV recovery device, which is based on the first embodiment. Figure 5 As shown, a base 8 and an interception assembly 9 are provided.

[0068] The base 8 includes a C-shaped groove, and the main housing 1 is arranged inside the C-shaped groove through a fixed shaft. The base 8 includes a base and side seats arranged at both ends of the bottom plate, and an opening structure 81 is opened on the side seat. The base 8 is fastened to the vehicle by screws or straps, and can be disassembled at any time when not in use. The two ends of the main housing 1 are fixed to the two side seats of the base 8 by a fixed shaft, and the main housing 1 and the side seats are connected by threads. When not in use or maintenance is required, the main housing 1 can be disassembled from the base 8.

[0069] The interception assembly 9 includes two telescopic rods 91, an interception net 92, a drive motor, a worm, a worm wheel and a connecting rod 93; the lower end of the telescopic rod 91 is fixed on a flange 94, the center hole of the flange 94 corresponds to the through hole on the side seat, and the connecting 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 and another through hole on the second side seat arranged in the second side seat opening structure 81, and the connecting rod 93 and the flange 9 4 is an interference fit, and the flange 94 rotates with the rotation of the connecting rod 93; the driving motor, worm and worm wheel are arranged on the side wall of the base 8 as driving components, the worm is arranged at the output end of the driving motor, and the worm wheel is arranged on the connecting rod 93, the worm wheel and the worm are meshed, the driving motor drives the worm to rotate, the worm drives the worm wheel to rotate, the worm wheel drives the connecting rod 93 to rotate, and the connecting rod 93 drives the flange 94 to drive the telescopic rod 91 to reciprocate between the horizontal position and the vertical position in the opening structure 81.

[0070] An interception net 92 is provided on the two telescopic rods 91. The interception net 92 is made of Kevlar fiber and can be detachably tied to the telescopic rods 91 by straps; alternatively, a hook structure is provided on the telescopic rods 91 to hang the interception net 92 on the telescopic rods 91, so as to facilitate the disassembly, maintenance and replacement of the interception net 92.

[0071] The interception assembly 9 is used in conjunction with the recovery 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 recovery net 5, and the drone can fly to the interception net 92, and use the interception effect of the interception net 92 to stop the drone.

[0072] Alternatively, in windy, rainy or snowy weather, although the UAV lands on the recovery net 5, there is also a risk of being blown away or even damaged.

[0073] In addition, the interception net 92 can be set 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. A waterproof layer is arranged on the upper part of the first layer structure. The interception net 92 covers the drone parked on the recovery net 5, which can achieve the functions of windproof and waterproof.

[0074] In the embodiment, when the wind is strong or the rain and snow are heavy, the drone cannot dock on the recovery net 5 or cannot fly to the interception net 92. The interception 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 drive motor 93 drives the telescopic 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 recovery net 5. No matter what the conditions are, the drone can be effectively recovered.

[0075] The recycling 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.

[0076] In the embodiment described, Figures 5 to 10 As shown, it also includes a linkage component.

[0080] During use, when the UAV lands on the recovery net 5, the recovery net 5 is driven to vibrate, and the recovery net 5 moves downward. The lower end surface of the recovery net 5 acts on the starting end 1013, and the starting end 1013 drives the starting column 1012 to move downward, so that the first transmission rope 102 at the lower end of the starting column 1012 moves downward, and the other end of the first transmission rope 102 pulls the other end of the lifting plate 10321 to move downward, and the other end of the lifting plate 10321 moves downward to form a slope, and the ball 1031 rolls from one end of the lifting plate 10321 to the other end of the lifting plate 10321. The ball 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 ball 1031 under the action of the reaction force, so that the interception component 9 rotates from the vertical position to the horizontal position, so that after the UAV lands on the recovery net 5, under the traction of the linkage component, the interception component 9 automatically falls on the recovery net 5 to prevent the strong wind from blowing the UAV away and causing damage to the UAV.

[0081] After use, the handle is turned, and the handle drives the connecting rod 93 to rotate, and the connecting rod 93 drives the interception assembly 9 to rotate from the horizontal position to the vertical position for the next use, or the interception assembly 9 intercepts the drone in the vertical position. When the handle drives the connecting rod 93 to rotate, the first gear 1043 set on the connecting rod 93 is driven to rotate, the first gear 1043 drives the transmission chain 1045 to rotate, the transmission chain 1045 drives the second gear 1044 to rotate, and the second gear 1044 drives the winding column 1042 to rotate, so that the second transmission rope 1041 is wound around the winding, and the second transmission rope 1041 pulls the other end of the lifting plate 10321 upward, and the ball 1031 moves with the lifting plate 10321 to the position against the flange 94.

[0082] The first transmission rope 102 is detachably arranged on the lower end surface of the starting column 1012. When in use, if the external environment is good and the UAV can accurately land on the recovery net 5, the connection between the first transmission rope 102 and the lower end surface of the starting column 1012 can be disconnected, that is, the transmission of the force between the starting member 101 and the action end 103 is disconnected. When the UAV lands on the recovery net 5, the interception component 9 will not automatically change from a vertical position to a horizontal position.

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.
