Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of UAV recovery, and particularly relates to a vehicle-mounted UAV recovery device. Background Art
[0002] Existing vehicle-mounted UAV recovery devices generally adopt a top-mounted form, placing the recovery device on the top of the vehicle to facilitate the takeoff and recovery of UAVs. However, this structural form increases the height of the vehicle. In the case of relatively strict height limit scenarios, the vehicle cannot pass through and must detour or remove the recovery device, thus greatly reducing the passing performance of the vehicle. Moreover, existing UAV recovery devices all use hard connections to fix the UAVs. When the vehicle is driving on bumpy roads, vibrations will be transmitted to the inside of the recovery device, and the hard connections are likely to directly transmit the vibrations to the UAVs, causing a certain degree of damage to the UAVs. Summary of the Invention
[0003] The present invention overcomes the deficiencies of the prior art and provides a vehicle-mounted UAV recovery device, solving the problem that the existing vehicle-mounted UAV recovery device must be set on the top of the vehicle and has insufficient vibration buffering.

A driving mechanism is arranged inside the box body. The driving mechanism is connected to the moving mechanism through a first transmission mechanism and is connected to the opening and closing mechanism through a second transmission mechanism. When the driving mechanism acts forward, the opening and closing mechanism controls the opening of the box door, and the moving mechanism controls the moving platform to move to the outside of the box body. When the driving mechanism acts in reverse, the moving mechanism controls the moving platform to return to the inside of the box body, and the opening and closing mechanism controls the closing of the box door. A locking mechanism is arranged on the moving platform. When the moving platform moves to the inside of the box body, the locking mechanism fixes the UAV.

[0013] Further, the locking mechanism includes a locking rope, a sliding seat, a spring, a fixed shaft, a chute, a top contact rod, and a top contact seat; a vertically penetrating chute is provided at each corner of the moving platform, and the chute extends towards the center of the moving platform; a sliding seat is slidably arranged in each chute, and the sliding seat includes a fixed main body, a slider, and an anti - detachment block; the slider is fixedly arranged between the upper fixed main body and the lower anti - detachment block, and the slider is slidably inserted into the chute; the width of the anti - detachment block is greater than the width of the chute, and the upper end surface of the anti - detachment block slidably contacts the lower end surface of the moving platform; the fixed main body is a U - shaped plate - like structure, the opening of the fixed main body faces horizontally towards the center of the moving platform, the lower end surface of the fixed main body slidably contacts the upper end surface of the moving platform, and the top plate and the bottom plate of the fixed main body are both semi - circular arc surface structures at the end towards the center of the moving platform; a vertical driven roller is rotatably arranged between the top plate and the bottom plate of the fixed main body, and the middle part of the outer side surface of the driven roller is a circular arc groove; a vertical fixed shaft is fixedly arranged at each of the four corners of the upper end surface of the moving platform, and the fixed shaft is located on the side of the sliding seat away from the center of the moving platform; a tension spring is fixedly arranged between the fixed shaft and the sliding seat at the same corner of the moving platform; the same locking rope is sleeved outside the driven rollers of the four sliding seats; the unmanned aerial vehicle is located at the center of the upper end surface of the moving platform, and the unmanned aerial vehicle is provided with four support feet arranged in a square array, and the support feet are vertically arranged cylindrical structures; two annular grooves are respectively arranged at the four support feet of the unmanned aerial vehicle, and the two annular grooves respectively correspond to the height of the top plate and the bottom plate of the sliding seat.
[0014] Furthermore, a top contact rod is fixedly arranged on the front inner wall of the box body. The top contact rod is located in the middle of the box body in the left - right direction and is horizontally arranged along the front - back direction; a top contact seat is fixedly arranged at the rear end of the top contact rod, and the height of the top contact seat is the same as that of the sliding seat; the top contact seat is a U - shaped plate - like structure, the opening of the top contact seat faces horizontally backward towards the center of the moving platform, and a driving roller is rotatably arranged between the top plate and the bottom plate of the top contact seat, and the middle part of the outer side surface of the driving roller is a circular arc groove; the driving roller is located in front of the locking rope; when the moving platform is at the front - most side inside the box body, the moving frame moves to the front - most side inside the box body. At this time, the driving roller inside the top contact seat presses the middle part of the front - side region segment of the locking rope forward, so that the middle part of the front - side region segment of the locking rope moves backward. At this time, the locking rope gives a pulling force towards the center of the moving platform to the driven roller inside the sliding seat, so that the sliding seat moves towards the center of the moving platform inside the chute, the tension spring is stretched, until the top plate and the bottom plate of the sliding seat are respectively clamped inside the upper and lower annular grooves of the four support feet of the unmanned aerial vehicle, and the four support feet of the unmanned aerial vehicle are clamped by the four sliding seats to prevent the unmanned aerial vehicle from sliding left and right. At the same time, because the top plate of the sliding seat is clamped inside the annular groove of the support foot of the unmanned aerial vehicle, a vertical limit is applied to the support foot of the unmanned aerial vehicle by the top plate of the sliding seat to prevent the unmanned aerial vehicle from moving up and down.
[0015] The beneficial effects of the present invention compared with the prior art are as follows: (1) For a vehicle-mounted UAV recovery device provided by the present invention, the recovery device is fixed to the rear side of the vehicle, without occupying the top space and the left and right spaces of the vehicle, so that the height and width of the vehicle will not be increased, and the passing performance of the vehicle will not be affected in the case of height limit or width limit scenarios.
[0016] (2) For a vehicle-mounted UAV recovery device provided by the present invention, the UAV in the recovery state is locked by a tension spring and a slidable sliding seat. When the vehicle encounters bumps, the UAV can make a certain amplitude of horizontal shaking under the action of the tension spring and the sliding seat, so as to buffer the UAV and greatly reduce the damage to the UAV caused by vehicle bumps.
[0017] (3) For a vehicle-mounted UAV recovery device provided by the present invention, only one power source, namely an electric push rod, can be used to realize the outward movement of the moving platform and the opening of the box door, saving power and ensuring that the operation logics of the two are always in a stable state without mutual interference.
[0018] (4) For a vehicle-mounted UAV recovery device provided by the present invention, during the process of the moving platform driving the UAV to move outwards or inwards, both the moving platform and the UAV are in a horizontal state, so as to ensure that the UAV will not slide on the moving platform.
[0019] (5) For a vehicle-mounted UAV recovery device provided by the present invention, through a uniquely designed moving mechanism, the moving platform can first move horizontally outwards, gradually lift during the process of moving outwards to the side, and then move horizontally outwards again after the lifting is completed, so that the moving platform can be located above the upper end face of the box body after moving outwards, thus ensuring that the box body will not interfere during the landing process of the UAV.

Detailed implementation manners
[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention will be further described in detail in combination with embodiments and drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. The technical solutions of the present invention will be described in detail below in combination with embodiments and drawings, but the protection scope is not limited by this.
[0022] As Figure 1 —20 shows, the present invention provides a vehicle-mounted UAV recovery device, including a recovery box 1. The recovery box 1 includes a box body 101 and a box door 102. The box body 101 is fixed to the rear end of the vehicle through a fixing frame 103. A moving platform 2 is arranged inside the box body 101 through a moving mechanism 3. The UAV 9 lands on the moving platform 2, and the moving mechanism 3 can move the moving platform 2 to the outside of the box body 101; the box door 102 is connected to the box body 101 through an opening and closing mechanism 4, and the box door 102 can be opened and closed through the opening and closing mechanism 4; a driving mechanism 5 is arranged inside the box body 101. The driving mechanism 5 is connected to the moving mechanism 3 through a first transmission mechanism 6, and the driving mechanism 5 is connected to the opening and closing mechanism 4 through a second transmission mechanism 7; when the driving mechanism 5 acts forward, the opening and closing mechanism 4 controls the box door 102 to open, and the moving mechanism 3 controls the moving platform 2 to move to the outside of the box body 101; when the driving mechanism 5 acts reversely, the moving mechanism 3 controls the moving platform 2 to return to the inside of the box body 101, and the opening and closing mechanism 4 controls the box door 102 to close; a locking mechanism 8 is arranged on the moving platform 2. When the moving platform 2 moves to the inside of the box body 101, the locking mechanism 8 fixes the UAV 9.
[0023] The recycling box 1 is a square box body 101 with an open rear end. A door 102 is provided at the rear end opening of the box body 101. A fixing bracket 103 is fixedly provided at each of the four corners of the front end of the box body 101. The box body 101 is fixedly connected to the rear end of the vehicle via the four fixing brackets 103.
[0024] The movable platform 2 is a horizontally arranged square plate-shaped structure. The movable platform 2 is arranged inside the box 101 and maintains a distance from the inner bottom surface of the box 101 .
[0025] The moving mechanism 3 includes a moving frame 301 , a slide plate, a guide rail 302 , and a first connecting rod 304 .
[0026] The movable frame 301 is arranged on the front side of the movable platform 2, and includes a horizontal plate 3011 and two vertical plates 3012 that are symmetrical on both sides. The horizontal plate 3011 is arranged to extend horizontally from left to right, and the horizontal plate 3011 maintains a distance from the bottom surface of the interior of the box body 101; the two vertical plates 3012 are both located in a vertical plane in the front-to-back direction, and the lower ends of the two vertical plates 3012 are fixedly connected to the left and right ends of the upper end surface of the horizontal plate 3011. Two symmetrical guide rails 302 are fixedly arranged on the left and right inner walls of the box body 101. The guide rails 302 are arranged horizontally in the front-to-back direction, and the two ends of the horizontal plate 3011 are respectively slidably engaged with the inside of the two guide rails 302. The guide rails 302 ensure that the movable frame 301 can only slide in the front-to-back horizontal direction.
[0027] A vertical mounting plate 303 is fixedly mounted at the front edge of the lower end face of the mobile platform 2. The left and right end faces of the mounting plate 303 are connected to the vertical plate 3012 on the same side via two first connecting rods 304. The first connecting rods 304 are located in a vertical plane in the front-to-back direction. The front end of the first connecting rod 304 is higher than the rear end of the first connecting rod 304. The front end of the first connecting rod 304 is hinged to the upper end of the rear edge of the vertical plate 3012, and the rear end of the first connecting rod 304 is hinged to the mounting plate 303. The two first connecting rods 304 are parallel to each other and of equal length. The two ends of the two first connecting rods 304 correspond to each other in the vertical direction, thereby forming a parallelogram-shaped first linkage mechanism between the two first connecting rods 304, the vertical plate 3012, and the mounting plate 303. This ensures that the mobile platform 2 remains level regardless of the movement of the mobile frame 301.
[0028] On the left and right inner walls of the box body 101, two symmetrically arranged sliding plates are fixedly provided. The two sliding plates are located on the left and right sides of the moving frame 301, and the sliding plates are located in the vertical plane in the front-rear direction. On each sliding plate, a slide rail 305 is respectively provided. The slide rail 305 includes a lower horizontal section 3051, a middle inclined section 3052, and an upper horizontal section 3053 that are interconnected. Among them, both the lower horizontal section 3051 and the upper horizontal section 3053 are horizontally arranged in the front-rear direction. The lower horizontal section 3051 is located below the front side of the upper horizontal section 3053. The rear end of the lower horizontal section 3051 and the front end of the upper horizontal section 3053 are transitionally connected by an inclined middle inclined section 3052. The front end height of the middle inclined section 3052 is lower than the rear end height.
[0029] On the outer side surfaces of the first link rods 304 above the left and right sides, a working rod 306 is respectively fixedly provided. The working rod 306 is perpendicular to the first link rod 304. The two working rods 306 are respectively inserted into the front end inside of the lower horizontal sections 3051 of the slide rails 305 of the left and right sliding plates, and the working rod 306 is in contact with the upper and lower inner walls of the lower horizontal section 3051.
[0030] At this time, the moving platform 2 is located at the innermost side of the box body 101. When the moving frame 301 moves along the guide rail 302 towards the rear opening of the box body 101, the working rod 306 on the first link rod 304 moves backward in the lower horizontal section 3051 of the slide rail 305. Under the action of the first link rod 304, the moving platform 2 also moves towards the rear opening of the box body 101.
[0031] When the working rod 306 on the first link rod 304 moves to the connection between the lower horizontal section 3051 and the middle inclined section 3052, the working rod 306 starts to slide inside the middle inclined section 3052, and the height of the working rod 306 gradually increases, causing the first link rod 304 to gradually lift upward. The first link rod 304 drives the moving platform 2 to lift upward. During this process, the moving platform 2 not only moves towards the outside of the rear opening of the box body 101, but also gradually lifts in height, and always remains horizontal during the movement.
[0032] When the working rod 306 on the first link rod 304 moves to the connection between the upper horizontal section 3053 and the middle inclined section 3052, the working rod 306 starts to slide inside the upper horizontal section 3053, and the height of the working rod 306 no longer changes, and the angle of the first link rod 304 also no longer changes. Then the height of the moving platform 2 no longer changes. During this process, the moving platform 2 moves horizontally backward. When the working rod 306 slides to the last end of the upper horizontal section 3053, the moving frame 301, the first link rod 304, and the moving platform 2 all stop moving. At this time, the moving platform 2 completely moves to the outside of the rear opening of the box body 101, and the moving platform 2 remains horizontal.
[0033] The opening and closing mechanism 4 includes a second connecting rod 401 and two third connecting rods 402.
[0034] One end of the second connecting rod 401 is hinged to the middle of the rear edge of the inner bottom surface of the box body 101 through a hinge seat, and the other end of the second connecting rod 401 is hinged to the center of the inner side surface of the box door 102 through a hinge seat. One ends of the two third connecting rods 402 are respectively hinged to the upper ends of the left and right side edges of the inner side surface of the box door 102 through hinge seats, and the other ends of the two third connecting rods 402 are respectively hinged to the middle of the rear edges of the left and right inner side walls of the box body 101 through hinge seats. The hinge axes at both ends of the second connecting rod 401 and the third connecting rods 402 are horizontally arranged along the left and right directions, that is, the second connecting rod 401 and the third connecting rods 402 both move in the front and rear vertical planes.
[0035] The shortest connection line length between the hinge axes at both ends of the second connecting rod 401 is equal to the shortest length between the hinge axes at both ends of the third connecting rod 402, so that a second connecting rod mechanism in the shape of a parallelogram is formed among the second connecting rod 401, the third connecting rods 402, the left and right inner side walls of the box body 101, and the box door 102, thereby ensuring that the box door 102 remains in a vertical state after being opened regardless of how the second connecting rod 401 and the third connecting rods 402 rotate.
[0036] The driving mechanism 5 includes an electric push rod 501 and a moving rod 502.
[0037] The cylinder body of the electric push rod 501 is fixedly arranged on the inner bottom surface of the box body 101 below the moving platform 2, the piston rod of the electric push rod 501 is horizontally forward, and a moving rod 502 is fixedly arranged at the end of the piston rod of the electric push rod 501 through a connecting piece. The moving rod 502 is horizontally arranged along the front and rear directions. A moving groove 503 is arranged at the inner bottom surface of the box body 101, the moving groove 503 is horizontally arranged along the front and rear directions, and the moving rod 502 is slidably arranged inside the moving groove 503, and the electric push rod 501 drives the moving rod 502 to reciprocate back and forth inside the moving groove 503 through telescoping.
[0038] The first transmission mechanism 6 includes a first gear 602, a first rack 606, a rotating shaft 601, a driving rod 604, a connecting rod 605, and a driving groove 603.
[0039] A vertical rotating shaft 601 is rotatably arranged at the inner bottom surface of the box body 101, and the rotating shaft 601 is located below the center of the moving platform 2; a first gear 602 is fixedly arranged outside the rotating shaft 601. A vertically penetrating driving groove 603 is arranged on the horizontal plate 3011 of the moving frame 301, and the driving groove 603 extends along the left - right direction; a vertical driving rod 604 is inserted into the driving groove 603, and the outer side surface of the driving rod 604 is in contact with the front and rear inner walls of the driving groove 603. The upper end of the rotating shaft 601 and the lower end of the driving rod 604 are fixedly connected by a connecting rod 605, and the connecting rod 605 is horizontally arranged along the front - rear direction.
[0040] The moving rod 502 is located on one side of the rotating shaft 601. A first rack 606 is fixedly arranged at the front end of the end face of the moving rod 502 close to the rotating shaft 601, and the first rack 606 is located in front of the first gear 602. At this time, the first rack 606 and the first gear 602 are in a non - meshing state. When the moving rod 502 moves backward a certain distance inside the moving groove 503, the first rack 606 meshes with the first gear 602.
[0041] The second transmission mechanism 7 includes a second rack 704, a second gear 701, a third gear 702, a synchronous belt transmission mechanism 703, and a fourth gear 705.

[0043] The rear end of the moving rod 502 is inserted into the front gear seat, and at this time, the rear end of the moving rod 502 is located below the second gear 701. A second rack 704 is fixedly arranged on the upper end face of the moving rod 502, and the second rack 704 is located behind the first rack 606. At this time, the rear end of the second rack 704 is in a preliminary meshing state with the second gear 701. When the moving rod 502 starts to move backward inside the moving groove 503, the second rack 704 drives the second gear 701 to rotate.
[0044] A fourth gear 705 is fixedly arranged on the hinge shaft between the second connecting rod 401 and the inner bottom surface of the box body 101. The fourth gear 705 is located behind the third gear 702 and meshes with the third gear 702.
[0045] The locking mechanism 8 includes a locking rope 806, a sliding seat 802, a spring, a fixed shaft 804, a chute 801, a top contact rod 807, and a top contact seat 808.
[0046] At each corner of the mobile platform ②, a vertically penetrating chute 801 is provided, and the chute 801 extends towards the center of the mobile platform ②. A sliding seat 802 is slidably arranged in each chute 801. The sliding seat 802 includes a fixed main body, a slider, and an anti - detachment block. The slider is fixedly arranged between the upper fixed main body and the lower anti - detachment block, and the slider is slidably inserted into the chute 801. The width of the anti - detachment block is greater than the width of the chute 801, and the upper end surface of the anti - detachment block is in sliding contact with the lower end surface of the mobile platform ②. The fixed main body is a U - shaped plate - like structure, the opening of the fixed main body faces horizontally towards the center of the mobile platform ②, the lower end surface of the fixed main body is in sliding contact with the upper end surface of the mobile platform ②, and the end portions of the top plate and the bottom plate of the fixed main body towards the center of the mobile platform ② are both semi - circular arc surface structures. A vertical driven roller 803 is rotatably arranged between the top plate and the bottom plate of the fixed main body, and the middle part of the outer side surface of the driven roller 803 is a circular arc groove. At the four corners of the upper end surface of the mobile platform ②, a vertical fixed shaft 804 is fixedly arranged, and the fixed shaft 804 is located on the side of the sliding seat 802 away from the center of the mobile platform ②. A tension spring 805 is fixedly arranged between the fixed shaft 804 and the sliding seat 802 at the same corner of the mobile platform ②. The same locking rope 806 is sleeved outside the driven rollers 803 of the four sliding seats 802.
[0047] A top contact rod 807 is fixedly arranged on the front inner wall of the box body 101. The top contact rod 807 is located in the middle of the box body 101 in the left - right direction, and the top contact rod 807 is horizontally arranged along the front - back direction. A top contact seat 808 is fixedly arranged at the rear end of the top contact rod 807. The top contact seat 808 has the same height as the sliding seat 802. The top contact seat 808 is a U - shaped plate - like structure, the opening of the top contact seat 808 faces horizontally backward towards the center of the mobile platform ②, and a driving roller 809 is rotatably arranged between the top plate and the bottom plate of the top contact seat 808. The middle part of the outer side surface of the driving roller 809 is a circular arc groove. The driving roller 809 is located in front of the locking rope 806.
[0048] The drone 9 is located at the center of the upper end surface of the mobile platform ②. The drone 9 is provided with four support feet 810 arranged in a square array. The support feet 810 are vertically arranged cylindrical structures. At the four support feet 810 of the drone 9, two upper and lower annular grooves 811 are respectively arranged, and the two annular grooves 811 respectively correspond to the height of the top plate and the bottom plate of the sliding seat 802. A landing positioning mark is arranged on the upper end surface of the mobile platform ② to guide the drone 9 to land.
[0049] When the mobile platform 2 is located at the foremost side inside the box body 101, the mobile frame 301 moves to the foremost side inside the box body 101. At this time, the driving roller 809 inside the top contact seat 808 presses forward the middle part of the front region section of the locking rope 806, causing the middle part of the front region section of the locking rope 806 to move backward. At this time, the locking rope 806 gives a pulling force towards the center of the mobile platform 2 to the driven roller 803 inside the sliding seat 802, causing the sliding seat 802 to move towards the center of the mobile platform 2 inside the sliding groove 801. The tension spring 805 is stretched until the top plate and the bottom plate of the sliding seat 802 are respectively clamped inside the annular grooves 811 above and below the four support feet 810 of the unmanned aerial vehicle 9. The four support feet 810 of the unmanned aerial vehicle 9 are clamped by the four sliding seats 802 to prevent the unmanned aerial vehicle 9 from sliding left and right. At the same time, since the top plate of the sliding seat 802 is clamped inside the annular groove 811 of the support foot 810 of the unmanned aerial vehicle 9, a vertical limit is applied to the support foot 810 of the unmanned aerial vehicle 9 by the top plate of the sliding seat 802 to prevent the unmanned aerial vehicle 9 from moving up and down.
[0050] When the mobile platform 2 moves towards the rear opening of the box body 101, the driving roller 809 inside the top contact seat 808 gradually disengages from the locking rope 806. Under the action of the resilient pulling force of the four tension springs 805, the sliding seat 802 slides towards the fixed shaft 804 side inside the sliding groove, and the tension spring 805 gradually contracts until the tension spring 805 returns to the contracted state. At this time, the locking rope 806 is a square ring structure, and the locking rope 806 is stretched to the maximum size by the tension spring 805 and the sliding seat 802. The locking rope 806 no longer clamps the support feet 810 of the unmanned aerial vehicle 9 through the sliding seat 802.
[0051] When the tension spring 805 is in the contracted state, the sliding seat 802 is located on the side of the sliding groove 801 close to the fixed shaft 804, and the distance between the sliding seat 802 and the fixed shaft 804 is the shortest; when the tension spring 805 is in the extended state, the sliding seat 802 is located on the side of the sliding groove 801 away from the fixed shaft 804, and the distance between the sliding seat 802 and the fixed shaft 804 is the longest.
[0052] The operation process of the present invention from the recovery state to the flying state is as follows: When the recycling device is in the recycling state, the mobile platform 2 and the mobile frame 301 are both at the frontmost side inside the box body 101, and the drone 9 is located at the center of the upper end face of the mobile platform 2; at this time, the box door 102 is in the closed state, and the piston rod of the electric push rod 501 is in the forward extended state; the first rack 606 and the first gear 602 are in the unmeshed state. When the moving rod 502 moves backward a certain distance inside the moving groove 503; the first rack 606 and the first gear 602 are meshed. The rear end of the second rack 704 and the second gear 701 are in the preliminary meshed state. When the moving rod 502 starts to move backward inside the moving groove 503, the second rack 704 drives the second gear 701 to rotate; the active roller 809 inside the abutting seat 808 squeezes the middle of the front side area section of the locking rope 806 backward, so that the top plates and bottom plates of the four sliding seats 802 are respectively clamped inside the annular grooves 811 above and below the four support feet 810 of the drone 9, and the four support feet 810 of the drone 9 are clamped by the four sliding seats 802.
[0053] When starting to move towards the flying state, the piston rod of the electric push rod 501 starts to contract backward. The piston rod drives the moving rod 502 to slide backward inside the moving groove 503. At this time, the second rack 704 and the second gear 701 are meshed. As the moving rod 502 slides backward, the second rack 704 drives the second gear 701 to rotate forward. The second gear 701 drives the third gear 702 to rotate forward through the synchronous belt transmission mechanism 703. The third gear 702 drives the fourth gear 705 to rotate backward. The fourth gear 705 drives the second connecting rod 401 to rotate downward. The second connecting rod 401 drives the box door 102 to rotate downward. Through the cooperation of the second connecting rod 401 and the third connecting rod 402, the box door 102 is always kept in the vertical state. When the second rack 704 completely passes by the second gear 701, the second gear 701, the third gear 702, the fourth gear 705, and the second connecting rod 401 all stop rotating. At this time, the box door 102 is located below the rear end opening of the box body 101, and at this time the box door 102 is in the vertical state, ensuring that the opened box door 102 does not occupy too much space.
[0054] As the moving rod 502 continues to slide backward, when the second rack 704 passes by the second gear 701, the first rack 606 and the first gear 602 start to mesh. The first gear 602 drives the rotating shaft 601 to rotate. The rotating shaft 601 drives the driving rod 604 to rotate forward around the rotating shaft 601 through the connecting rod 605. Since the driving rod 604 is in sliding contact with the driving groove 603 of the horizontal plate 3011 of the mobile frame 301, when the driving rod 604 rotates forward, a horizontal backward acting force is given to the mobile frame 301, so that the mobile frame 301 moves horizontally backward inside the guide rails 302 on both sides.
[0055] When the moving frame 301 moves along the guide rail 302 towards the rear opening of the box body 101, the acting rod 306 on the first connecting rod 304 moves rearward in the lower horizontal section 3051 of the sliding rail 305. Under the action of the first connecting rod 304, the moving platform 2 also moves towards the rear opening of the box body 101. As the moving frame 301 drives the moving platform 2 to gradually move backward, the driving roller 809 inside the abutting seat 808 gradually disengages from the locking rope 806. Under the resilient pulling force of the four tension springs 805, the sliding seat 802 slides towards the fixed shaft 804 inside the sliding groove, and the tension springs 805 gradually contract until the tension springs 805 return to the contracted state. At this time, the locking rope 806 is in a square ring structure, and the locking rope 806 is stretched to the maximum size by the tension springs 805 and the sliding seat 802. The locking rope 806 no longer clamps the support feet 810 of the drone 9 through the sliding seat 802, and at this time, the drone 9 is in the unlocked state.
[0056] As Figure 18 shown, when the acting rod 306 on the first connecting rod 304 moves to the connection point of the lower horizontal section 3051 and the middle inclined section 3052, the acting rod 306 begins to slide inside the middle inclined section 3052, and the height of the acting rod 306 gradually increases, causing the first connecting rod 304 to gradually lift upward. The first connecting rod 304 drives the moving platform 2 to lift upward. During this process, the moving platform 2 not only moves towards the outside of the rear opening of the box body 101, but also gradually increases in height and remains horizontal during the movement. The moving platform 2 drives the drone 9 to move towards the upper rear side and keeps the drone 9 in a horizontal state during the movement. [[ID=||]]
[0057] As Figure 19 shown, when the acting rod 306 on the first connecting rod 304 moves to the connection point of the upper horizontal section 3053 and the middle inclined section 3052, the acting rod 306 begins to slide inside the upper horizontal section 3053, the height of the acting rod 306 no longer changes, and the angle of the first connecting rod 304 also no longer changes, then the height of the moving platform 2 no longer changes. During this process, the moving platform 2 moves horizontally backward.
[0058] As Figure 20 shown, when the acting rod 306 slides to the rearmost end of the upper horizontal section 3053, the moving frame 301, the first connecting rod 304, and the moving platform 2 all stop moving. At this time, the moving platform 2 has completely moved to the outside of the rear opening of the box body 101 and remains horizontal. At this time, the drone 9 reaches the release position
[0059] At this time, the drone 9 can perform the release operation.
[0060] The operation process of the present invention from the release state to the recovery state is as follows: After the UAV 9 completes its flight operation, it lands on the mobile platform 2 by means of the landing positioning mark on the mobile platform 2.
[0061] At this time, the piston rod of the electric push rod 501 starts to extend forward. The piston rod drives the moving rod 502 to slide forward inside the moving groove 503, and the moving rod 502 drives the first rack 606 and the second rack 704 to slide forward. The first rack 606 starts to drive the first gear 602 to rotate, the first gear 602 drives the rotating shaft 601 to rotate, and the rotating shaft 601 drives the driving rod 604 to rotate in the reverse direction through the connecting rod 605. The driving rod 604 gives a horizontally forward acting force to the moving frame 301, so that the moving frame 301 moves horizontally forward inside the guide rails 302 on both sides, and the moving frame 301 gradually retracts into the box body 101.
[0062] The mobile platform 2 moves into the box body 101 together with the moving frame 301 through the connecting rod. When the acting rod 306 on the first connecting rod 304 slides inside the middle inclined section 3052, the height of the acting rod 306 gradually decreases, causing the first connecting rod 304 to gradually rotate downward, and the first connecting rod 304 drives the mobile platform 2 to lower. During this process, the mobile platform 2 not only moves forward inside the front side of the box body 101, but also gradually decreases in height, and remains horizontal during the movement. When the acting rod 306 on the first connecting rod 304 slides to the lower horizontal section 3051, the height of the UAV 9 decreases to correspond to the height inside the box body 101. When the acting rod 306 on the first connecting rod 304 slides inside the lower horizontal section 3051, the height of the mobile platform 2 no longer changes, and the UAV 9 gradually retracts into the box body 101 along with the mobile platform 2.
[0063] When the mobile platform 2 drives the drone 9 to slide into the interior of the box body 101, the driving roller 809 inside the abutting seat 808 gradually contacts the middle of the front region section of the locking rope 806, and gradually presses forward the middle of the front region section of the locking rope 806, causing the middle of the front region section of the locking rope 806 to move backward. At this time, the locking rope 806 gives a pulling force towards the center of the mobile platform 2 to the driven roller 803 inside the sliding seat 802, causing the sliding seat 802 to move towards the center of the mobile platform 2 inside the sliding groove 801. The tension spring 805 is stretched until the top plate and the bottom plate of the sliding seat 802 are respectively clamped inside the annular grooves 811 above and below the four support feet 810 of the drone 9. The four support feet 810 of the drone 9 are clamped by the four sliding seats 802 to prevent the drone 9 from sliding left and right. At the same time, since the top plate of the sliding seat 802 is clamped inside the annular groove 811 of the support foot 810 of the drone 9, a vertical limit is applied to the support foot 810 of the drone 9 by the top plate of the sliding seat 802 to prevent the drone 9 from moving up and down. And because tension springs 805 are arranged on the outer sides of the sliding seats 802, during the movement of the vehicle, the support feet 810 of the drone 9 can horizontally shake within a certain range under the action of the tension springs 805 on the outer sides of the sliding seats 802, thereby buffering the drone 9 to ensure that the drone 9 is not damaged.
[0064] When the mobile platform 2 is completely retracted, the first rack 606 is disengaged from the first gear 602, and the moving rod 502 continues to slide forward until the second rack 704 meshes with the second gear 701. The second rack 704 drives the second gear 701 to rotate in the reverse direction. The second gear 701 drives the third gear 702 to rotate in the reverse direction through the synchronous belt transmission mechanism 703. The third gear 702 drives the fourth gear 705 to rotate in the forward direction. The fourth gear 705 drives the second connecting rod 401 to rotate upward. The second connecting rod 401 drives the box door 102 to rotate upward. Through the cooperation of the second connecting rod 401 and the third connecting rod 402, the box door 102 is always kept in a vertical state. When the second rack 704 completely passes by the second gear 701, the second gear 701, the third gear 702, the fourth gear 705, and the second connecting rod 401 all stop rotating. At this time, the box door 102 is located at the rear opening of the box body 101, and the piston rod of the electric push rod 501 stops extending, and the recovery device returns to the initial state.
