[0028] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1

[0030] A vehicle-mounted drone lifting and expansion nest, such as Figures 1-10 As shown, it includes a mounting base 1, a multi-stage hydraulic cylinder 3 is arranged on the upper left side of the mounting base 1, the telescopic end of the multi-stage hydraulic cylinder 3 is arranged to face upward, and a lifting frame 2 is connected to the telescopic end of the multi-stage hydraulic cylinder 3, and the lifting frame 2 is used to place the fixed-wing UAV. The bottom of the lifting frame 2 is in contact connection with the mounting base 1, and also includes: a clamping mechanism 4, the clamping mechanism 4 is arranged on the lifting frame 2, and the clamping mechanism 4 is used to adaptively clamp and stabilize the fixed-wing UAV; a supporting mechanism 5, the supporting mechanism 5 is arranged between the mounting base 1 and the lifting frame 2, and the supporting mechanism 5 is used to pull the clamping mechanism 4 to maintain overall stability.

[0031] It should be noted that this device can be used to assist in placing a vehicle-mounted drone. First, the mounting base 1 is placed and installed, and then the fixed-wing drone is placed and clamped by relying on the clamping mechanism 4 to maintain the stability of the fixed-wing drone. When the drone needs to take off, first rely on the vehicle-mounted device to push out the mounting base 1, and then rely on the telescopic end of the multi-stage hydraulic cylinder 3 to drive the lifting frame 2 to move upward. At this time, the support mechanism 5 will undergo adaptive changes, and then release the clamping mechanism 4. In the process of loosening the clamping mechanism 4, the support mechanism 5 will relax its pull on the clamping mechanism 4, so that the clamping mechanism 4 can shake to a certain extent, thereby providing a buffer condition for the fixed-wing drone to take off.

[0032] The clamping mechanism 4 includes a mounting seat 41. Two mounting seats 41 are provided on the lifting frame 2. Two sliding seats 43 symmetrical on the left and right are slidably connected to the mounting seat 41. The sliding seats 43 are both slidably connected to the lifting frame 2. Two rotating frames 44 are rotatably connected to the sliding seat 43 on the right. Elastic fittings 42 are provided on the upper part of the rotating frame 44 and the upper part of the sliding seat 43 on the left. The elastic fittings 42 are used to protect the fixed-wing UAV. Adjustment motors 45 are provided on the front and rear sides of the sliding seat 43 on the right. The output shaft of the adjustment motor 45 is connected to the adjacent rotating frame 44. A first drive motor 46 is provided on the upper right side of the lifting frame 2. The output shaft of the first drive motor 46 is set to the left. A first screw rod 47 is connected to the output shaft of the first drive motor 46. The first screw rod 47 is rotatably connected to the lifting frame 2 and the sliding seat 43 on the left. The first screw rod 47 is threadedly connected to the sliding seat 43 on the right.

[0033] It should be noted that when placing the fixed-wing UAV, it is first necessary to control the output shaft of the first drive motor 46 to drive the first screw rod 47 to rotate, so that the sliding seat 43 on the right moves to the right to open the distance, thereby providing a placement space for the fixed-wing UAV, and then the fixed-wing UAV is placed vertically between the two sliding seats 43, and then the output shaft of the first drive motor 46 is controlled to rotate so that the first screw rod 47 starts to rotate. The rotation of the first screw rod 47 will drive the sliding seat 43 on the right to move to the left and reset. When the sliding seat 43 on the right is about to approach the fixed-wing UAV, the first drive motor 46 is turned off, and then the adjustment motor 45 is started. The rotation of the output shaft of the adjustment motor 45 will drive the rotating frame 44 to rotate, so that the elastic fitting 42 on the right is in contact with the fixed-wing UAV, and then the adjustment motor 45 is turned off, and the first drive motor 46 is controlled to adjust the position of the right sliding seat 43 so that the elastic fittings 42 on the left and right sides can cooperate to complete the clamping and stabilization of the fixed-wing UAV. This clamping method is more adaptable and has stronger adjustability, and can adapt to the placement of fixed-wing UAVs of different sizes.

[0034] The support mechanism 5 includes a limited slide groove 51, a limited slide groove 51 is provided on the upper left side of the mounting base 41, and two multi-stage sleeves 52 are provided on the upper left side of the mounting base 1, which are symmetrical in front and back. The top of the multi-stage sleeve 52 is provided with an L-shaped mounting member, which is connected to the lifting frame 2. A take-up motor 53 is installed on the mounting member, and a pulling assembly 54 is provided between the take-up motor 53 and the limited slide groove 51 on the same side. The pulling assembly 54 consists of a winding wheel, a pull rope and a sliding frame. The winding wheels are connected to the adjacent take-up motor 53 output. The shaft is connected, and the sliding frames are slidably connected to the adjacent limiting slide grooves 51. The pull ropes are wound around the corresponding winding wheels and connected to the top of the sliding frames. The sliding frames are provided with a first rack rack 55. The front and rear sides of the sliding seat 43 on the right are connected to the second rack rack 56. The outer side of the mounting seat 41 is provided with a cover plate 57. The outer side of the mounting seat 41 is rotatably connected with a gear 58. The gears 58 are located between the adjacent cover plates 57 and the mounting seat 41. The gears 58 are meshed with the adjacent first rack racks 55 and the second rack racks 56.

[0035] It should be noted that when it is necessary to control the right sliding seat 43 to move to the right to clamp and stabilize the fixed-wing UAV, the take-up motor 53 is first started to release the pull rope, and then the right sliding seat 43 is controlled to move normally. As the right sliding seat 43 moves to the left, the second rack 56 will move to the left synchronously. At this time, the gear 58 will be rotated by the force of the second rack 56, so that the first rack 55 will move to the right. As the first rack 55 moves to the right, the sliding frame will also move to the right, thereby causing the released The pulled rope is straightened, and the pulling component 54 is used to pull the mounting seat 41 near the center to avoid the device from tilting and deforming due to the weight of the fixed-wing UAV when the lifting frame 2 and the mounting seat 41 are lifted upward, thereby further improving the stability of the device. It should be noted that when the lifting frame 2 and the mounting seat 41 are lifted upward, the wire-reeling motor 53 will be driven by the lifting frame 2 to move upward synchronously. At this time, the multi-stage sleeve 52 will extend and unfold, so that the pulling component 54 can move synchronously with the mounting seat 41 and the lifting frame 2 to ensure normal traction.

[0036] Example 2

[0037] On the basis of Example 1, a positioning and placement mechanism 6 is also included. The positioning and placement mechanism 6 includes a mounting groove 61. A mounting groove 61 is provided between the upper and middle parts of the mounting seat 41. Two first positioning columns 62 that are symmetrical front and back are connected to the inner side of the mounting seat 41. Two sliding blocks 63 that are symmetrical front and back are slidably connected to the mounting groove 61. The sliding blocks 63 are rotatably connected to the second positioning columns 64. Two torsion springs 65 are connected between the second positioning columns and the adjacent sliding blocks 63. The torsion springs 65 are used to provide adaptive buffering capacity for the adjacent second positioning columns 64. A second drive motor 66 is installed on the front mounting seat 41. The output shaft of the second drive motor 66 is set to face backward. A second screw rod 68 is connected to the output shaft of the second drive motor 66. A mounting liner 67 is provided on the right side of the mounting groove 61. The mounting liner 67 is rotatably connected to the second screw rod 68, and the second screw rod 68 is threadedly connected to the sliding block 63.

[0038] It should be noted that when placing a fixed-wing UAV, in order to improve the efficiency of placing the fixed-wing UAV, a positioning security mechanism can be relied upon to adapt and guide the fixed-wing UAV. At this time, the output shaft of the second drive motor 66 can be controlled to rotate according to the model of different fixed-wing UAVs, so that the second screw 68 rotates, and then the position of the sliding block 63 is adjusted. As the position of the sliding block 63 is adjusted, the second positioning column 64 will be adjusted to move. Then, the fixed-wing UAV will be placed according to the guidance of the first positioning column 62 and the second positioning column 64. On the one hand, the placement efficiency of the fixed-wing UAV is improved. On the other hand, relying on the first positioning column 62 and the second positioning column 64, the fixed-wing UAV can also be stabilized in advance to avoid the UAV from tipping over and rolling over during the clamping process.

[0039] It also includes a first buffer mechanism 7, which includes a limiting rubber sleeve 71. The limiting rubber sleeve 71 is arranged in the installation groove 61 and on the sliding seat 43. A second contact plate 73 is slidably connected between the limiting rubber sleeves 71 on the sliding seat 43, and a second contact plate 73 is slidably connected between the limiting rubber sleeves 71 in the installation groove 61. The first contact plate 72 and the second contact plate 73 are connected by a connecting rod, and a first spring 74 is connected between the first contact plate 72, the second contact plate 73 and the adjacent limiting rubber sleeves 71.

[0040] It should be noted that when placing a fixed-wing UAV, the first contact plate 72 and the second contact plate 73 are in contact with the fixed-wing UAV, so that the gravity of the fixed-wing UAV generates a downward force, causing the first spring 74 to begin to be compressed, which plays a certain protective and guiding role in the placement of the fixed-wing UAV.

[0041] It also includes a dust removal mechanism 8, which includes a limit frame 83. Two limit frames 83 are connected to the sliding seat 43. Adjacent limit frames 83 are slidably connected with electric guide rails 81. Two second springs 84 are connected between the electric guide rails 81 and the adjacent limit frames 83. The electric guide rails 81 are slidably connected with air outlet components 82. The air outlet components 82 are used to remove dust from the fixed-wing UAV.

[0042] It should be noted that when the fixed-wing UAV is placed, the electric guide rail 81 can adapt to the specifications of the fixed-wing UAV by relying on the force of the second spring 84. When the fixed-wing UAV is placed, the electric guide rail 81 is started to control the movement of the air outlet component 82 to perform dust removal operations on the fixed-wing UAV.

[0043] It also includes a second buffer mechanism 9, which includes a first fixing sleeve 91. Two groups of first fixing sleeves 91 are symmetrical front and back provided on the upper right side of the mounting base 1. Second fixing sleeves 92 are slidably connected to the inside of the first fixing sleeves 91. The second fixing sleeves 92 are in contact with the bottom of the mounting seat 41. A third spring 93 is connected between the second fixing sleeve 92 and the adjacent first fixing sleeve 91.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
