Detailed implementation manners

[0028] The present invention will be specifically described below with reference to the accompanying drawings.

[0029] An extended storage device for an in-vehicle drone, as Figure 1 and Figure 2 shown, includes a lifting platform 1, telescopic plates 2, flipping plates 3, a first double-acting cylinder 4, and a lifting mechanism 5. Telescopic plates 2 that are symmetric front and back are slidably connected to the upper part of the lifting platform 1. Flipping plates 3 are rotatably connected to both telescopic plates 2. Flipping plates 3 are also rotatably connected to both the left and right sides of the upper part of the lifting platform 1. First double-acting cylinders 4 are connected to both the left and right parts of the lifting platform 1. The expansion rods of the first double-acting cylinders 4 are all arranged in the front and back directions. The expansion rods of the first double-acting cylinders 4 are all connected to the corresponding telescopic plates 2. A lifting mechanism 5 for driving the flipping plates 3 to automatically close is provided on the lifting platform 1.

[0030] It should be noted that this device is used for storing and placing in-vehicle drones. When placing the drone, it only needs to be placed on the top of the lifting platform 1. After the placement is completed, the lifting platform 1 is controlled to descend, so that the lifting mechanism 5 works in synchronization, causing the flipping plates 3 to flip upward. When the flipping plate 3 flips 90 degrees, the telescopic rods of the first double-acting cylinders 4 are controlled to start contracting according to the specifications and models of the drones, so that the telescopic plates 2 contract along the lifting platform 1, achieving the effect of adapting to drones of different specifications.

[0031] As Figure 1 , Figure 3 and Figure 4 shown, the lifting mechanism 5 includes a first fixed seat 51, a first wire reel 52, a first pulling rope 53, a second wire reel 54, a second pulling rope 55, a connecting member 56, a reset plate 57, a rotating plate 58, a gear 59, a rack 510 and a first torsion spring 511. Two first fixed seats 51 are connected to the lower part of the lifting platform 1, and two first wire reels 52 are rotatably connected to each of the first fixed seats 51. The first pulling ropes 53 are connected to the first wire reels 52, and the first pulling ropes 53 are all connected to the lifting platform 1. First torsion springs 511 are connected between the first wire reels 52 and the adjacent first fixed seats 51. Second wire reels 54 are rotatably connected to the middle positions of the first fixed seats 51, and the second pulling ropes 55 are wound around the second wire reels 54. Connecting members 56 are connected to the bottoms of the left and right flipping plates 3, and the second pulling ropes 55 are all connected to the adjacent connecting members 56. Four reset plates 57 for pushing the left and right flipping plates 3 to automatically flip upward are rotatably connected to the upper part of the lifting platform 1, and first torsion springs 511 are also connected between the reset plates 57 and the lifting platform 1. Rotating plates 58 for pushing the front and back flipping plates 3 to automatically flip upward are rotatably connected to the bottoms of the telescopic plates 2. The reset plates 57 and the rotating plates 58 are both L-shaped structures. Gears 59 are connected to the left and right sides of the rotating plate 58, and racks 510 meshing with the adjacent gears 59 are connected to the upper part of the lifting platform 1.

[0032] It should be noted that in the initial state, the first torsion springs 511 are all in a deformed state under force. As the lifting platform 1 starts to descend in height, the first wire reels 52 will start to wind up the first pulling ropes 53 under the action of the first torsion springs 511. At the same time, the second wire reels 54 will start to release the second pulling ropes 55. In this state, the first torsion springs 511 will also push the reset plates 57 to flip upward, thereby pushing the adjacent flip plates 3 to flip upward, causing the left and right flip plates 3 to flip upward and close. At the same time, as the telescopic plates 2 start to contract, the gears 59 will contact the corresponding racks 510, causing the corresponding gears 59 to start rotating, and further causing the front and rear flip plates 3 to flip upward. At this time, the four flip plates 3 have all completed the automatic upward flipping to automatically protect the drones on the lifting platform 1. Similarly, when the lifting platform 1 starts to rise, the first wire reels 52 will release the first pulling ropes 53, the first torsion springs 511 will return to the deformed state under force, and the second wire reels 54 will start to wind up the second pulling ropes 55, causing the left and right flip plates 3 to automatically flip open. And under the mutual cooperation of the gears 59 and the racks 510, the front and rear flip plates 3 will also automatically flip downward and open, so that the drones are no longer blocked and can take off freely. To sum up, by controlling the descent of the lifting platform 1, the first wire reels 52 and the second wire reels 54 start to work correspondingly, and then the flip plates 3 can automatically flip upward to automatically enclose and protect the drones on the lifting platform 1, improving the convenience during use.

[0033] As Figure 1 and Figure 5 shown, it further includes a stabilizing mechanism 6. The stabilizing mechanism 6 includes a hydraulic component 61, a placement plate 62, a second fixing seat 63, a dual-axis motor 64, and a stabilizing plate 65. Hydraulic components 61 are connected to the four corners of the top of the lifting platform 1. A placement plate 62 for placing the drones is connected between the top ends of the telescopic ends of the hydraulic components 61. The placement plate 62 is provided with a limiting groove for limiting the drones. Four second fixing seats 63 are connected to the upper sides of the left and right parts of the placement plate 62. A dual-axis motor 64 is connected between the adjacent front and rear second fixing seats 63. The output shafts of the dual-axis motors 64 are all arranged in the front-rear direction. Stabilizing plates 65 for pressing and limiting the landing gears of the drones are connected to the output shafts of the dual-axis motors 64. The stabilizing plates 65 are all provided with soft pads.

[0034] It should be noted that when placing and storing the drone, the drone can be directly placed on the placement board 62. The drone is initially placed and positioned by relying on the limit slots on the placement board 62. Then, control the output shaft of the biaxial motor 64 to rotate, so that the stabilizing plates 65 all flip upward and open. After the drone is placed, control the output shaft of the biaxial motor 64 to rotate in the reverse direction, so that the stabilizing plates 65 can all contact the landing gear of the drone and press and limit the landing gear of the drone, improving the stability during the placement process of the drone. When the drone needs to take off, the telescopic end of the hydraulic cylinder can be synchronously controlled to move upward, thereby increasing the takeoff height of the drone. In summary, by positioning and placing the drone through the placement board 62, the placement of the drone is made more convenient. After the placement is completed, the cooperation between the biaxial motor 64 and the stabilizing plates 65 is relied on to complete the pressing and limiting of the landing gear of the drone, improving the stability of the drone during the placement and storage process.

[0035] As Figure 1 and Figure 6 shown, it further includes a hemming mechanism 7. The hemming mechanism 7 includes a third fixing seat 71, a hemming plate 72, and a second torsion spring 73. The lower sides of the front and rear parts of the left and right flip plates 3 are both connected with a third fixing seat 71. A hemming plate 72 for blocking the gap between the flip plates 3 is rotatably connected to each third fixing seat 71. Two left and right second torsion springs 73 are connected between the hemming plate 72 and the adjacent third fixing seat 71.

[0036] It should be noted that after the flip plates 3 all start to flip upward and close, there will be a gap between the flip plates 3. In order to prevent air flow from entering the inside between the flip plates 3 through the gap and impacting the drone, at this time, the cooperation between the hemming plate 72 and the second torsion spring 73 is relied on to block the gap, so that after the flip plates 3 all flip upward and are completed, the drone can be in a state with relatively stable air flow. In summary, after the flip plates 3 all flip upward and close, the cooperation between the hemming plate 72 and the corresponding second torsion spring 73 is relied on to block the gap between the flip plates 3, preventing air flow from passing through the gap and affecting the normal placement of the drone.

[0037] As Figure 1 and Figure 7As shown in the figure, it further includes a limiting mechanism 8. The limiting mechanism 8 includes a driving component 81, a guide rod 82, and a limiting plate 83. A driving component 81 is connected to the lower left side of the placing plate 62. The driving component 81 includes a bidirectional motor, a motor base, a lead screw, and a mounting member. The motor base is connected to the lower left side of the placing plate 62, and a bidirectional motor is connected to the motor base. The output shaft of the bidirectional motor is arranged in the front-back direction, and lead screws are connected to both output shafts of the bidirectional motor. Two symmetrically arranged mounting members are connected to the lower left side of the placing plate 62 by bolts, and the mounting members are rotatably connected to the adjacent lead screws respectively. A guide rod 82 is connected to the lower right side of the placing plate 62, and two symmetrically arranged limiting plates 83 for limiting and stabilizing the fuselage of the drone are slidably connected to the guide rod 82. The limiting plates 83 are threadedly connected to the driving component 81 respectively.

[0038] It should be noted that after the drone is placed, control the driving component 81 to operate, so that the limiting plates 83 slide close to each other along the guide rod 82, thereby clamping and limiting the fuselage of the drone on the placing plate 62, avoiding severe shaking caused by the overweight of the drone fuselage, and further improving the placing stability of the drone.

[0039] As Figure 1 and Figure 8 As shown in the figure, it further includes a clamping mechanism 9. The clamping mechanism 9 includes a second bidirectional cylinder 91 and a clamping member 92. The second bidirectional cylinders 91 are connected to the upper sides of the front and rear parts of the placing plate 62 respectively. The telescopic rods of the second bidirectional cylinders 91 are arranged in the left-right direction, and clamping members 92 for cooperating with the adjacent stabilizing plates 65 to press and limit the carbon tube frame of the drone are connected to the telescopic rods of the second cylinders respectively.

[0040] It should be noted that when the drone needs to be placed, first control the telescopic rods of the second bidirectional cylinders 91 to start contracting, so that the clamping members 92 no longer engage with the adjacent stabilizing plates 65. Then, normally control the stabilizing plates 65 to flip to press and limit the landing gear of the drone. After the pressing is completed, control the telescopic rods of the second bidirectional cylinders 91 to start extending, so that the clamping members 92 engage with the adjacent stabilizing plates 65 respectively. On the one hand, further lock the stabilizing plates 65, and on the other hand, cooperate with the stabilizing plates 65 to press and limit the carbon tube of the drone.

[0041] As Figure 1 and Figure 9 As shown in the figure, it further includes a buffer mechanism 10. The buffer mechanism 10 includes a spring 101 and a buffer plate 102. Four springs 101 are connected to the tops of the left and right turning plates 3, and a buffer plate 102 is connected between the tops of the adjacent four springs 101.

[0042] It should be noted that when both the left and right flip plates 3 are flipped upward, the cooperation between the buffer plate 102 and the spring 101 is relied on to perform a certain buffering and limiting on both sides of the drone, avoiding direct collision between the drone and the flip plate 3 and causing damage to the drone.
