It has the important functions of supporting the aircraft, reducing the landing impact, and providing a suspension device. When a vehicle-mounted drone takes off and lands, it needs to rely on a carrier vehicle as a carrier. The existing vehicle-mounted drone landing gear lifting and stabilization device generally drives the drone to a high altitude through simple lifting, allowing the drone to move to a suitable take-off altitude and avoid the drone being restricted by the carrier vehicle. However, the existing device is difficult to ensure the stability of the drone during the lifting process.

DETAILED DESCRIPTION

[0029] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] A vehicle-mounted UAV landing gear lifting and stabilization device, such as Figure 1 and Figure 2 As shown, it includes a base 1, a multi-stage cylinder 2, a connecting frame 3, a placement frame 4, a lifting component 5, a lifting and stabilizing mechanism 6 and a lifting mechanism 7. The multi-stage cylinder 2 is connected to the upper left side of the base 1, and the telescopic rod of the multi-stage cylinder 2 is set to face upward. The upper end of the telescopic rod of the multi-stage cylinder 2 is connected to the connecting frame 3. The placement frame 4 for placing the drone is slidably connected to the connecting frame 3. The right part of the connecting frame 3 is connected to a lifting component 5 for driving the placement frame 4 to automatically lift and lower. The lifting component 5 includes a driving motor and a screw rod. The driving motor is connected to the lower right side of the connecting frame 3. The output shaft of the driving motor is set to face upward. The output shaft of the driving motor is connected to the screw rod, and the screw rod is rotatably connected to the connecting frame 3. The connecting frame 3 is provided with a lifting and stabilizing mechanism 6 for stabilizing the lifting of the placement frame 4. The lifting and stabilizing mechanism 6 is provided with a lifting mechanism 7 for lifting and reinforcing the suspended position on the right side of the placement frame 4.

[0031] When the lifting frame 4 is lifted up, the lifting stabilization mechanism 6 will stabilize the connecting frame 3 in the front and rear directions, and the lifting mechanism 7 will pull the suspended position on the right side of the placing frame 4 to ensure the overall stability of the placing frame 4, avoid violent shaking during the lifting of the placing frame 4, and improve the stability of the drone's take-off operation.

[0032] like Figure 1 and Figure 3 As shown, the lifting and stabilizing mechanism 6 includes a lifting kit 61, a mounting frame 62 and a connecting plate 63. The upper left side of the base 1 is connected to the front and rear symmetrical lifting kits 61, the tops of the lifting kits 61 are connected to the mounting frames 62, and the connecting plates 63 are connected between the tops of the mounting frames 62. The connecting plates 63 are connected to the top of the connecting frame 3.

[0033] It should be noted that when the multi-stage cylinder 2 is started and the connecting frame 3 begins to lift upward, as the connecting frame 3 moves upward, the connecting frame 3 will drive the connecting plate 63 to move upward synchronously. At this time, the connecting plate 63 will drive the front and rear mounting frames 62 to move upward, thereby causing the lifting kit 61 to begin to extend, and the mounting frame 62 is supported by the extension movement of the lifting kit 61, so that the connecting frame 3 can maintain stability during the lifting process. In summary, the upward movement of the connecting frame 3 drives the connecting plate 63 to move, so that the mounting frame 62 drives the adjacent lifting kits 61 to extend synchronously, so that both the front and rear sides of the connecting frame 3 can be supported, reducing the shaking amplitude of the connecting frame 3 during the lifting process, and improving the stability of the lifting of the connecting frame 3.

[0034] like Figure 1 and Figure 4As shown, the lifting mechanism 7 includes a rack rack 71, a first mounting seat 72, a take-up wheel 73, a gear 74, a pull rope 75 and a lifting ear 76. The left side of the placement frame 4 is connected to a front-to-back symmetrical rack rack 71, and a rib is connected to the rack rack 71. The outer side of the upper part of the mounting frame 62 is connected to the first mounting seat 72, and the first mounting seat 72 is rotatably connected to the take-up wheel 73. The inner side of the take-up wheel 73 is connected to a gear 74 that meshes with the adjacent rack rack 71. The take-up wheel 73 is wound with a pull rope 75 for lifting and reinforcing the placement frame 4. The upper right side of the placement frame 4 is connected to a front-to-back symmetrical lifting ear 76, and the pull rope 75 is connected to the adjacent lifting ear 76.

[0035] When the lifting lever 74 is in the upright position, the pull rope 75 is pulled up to lift the lifting eye 76, thereby providing support for the right side of the lifting lever 4, thereby preventing the right side of the lifting lever 4 from floating and causing a decrease in stability. At the same time, as the lifting lever 4 begins to lift up, the lifting lever 4 drives the rack rack 71 to move upward, thereby causing the rack rack 71 to contact with the gear 74. After the rack rack 71 contacts with the gear 74, as the rack rack 71 moves upward, the gear 74 begins to rotate, thereby causing the take-up wheel 73 to start rotating synchronously. When the take-up wheels 73 start rotating, the pull rope 75 is reeled in, so that the pull rope 75 is always kept taut, thereby preventing the pull rope 75 from loosening and causing the right side of the lifting lever 4 to lose its support. When the lifting lever 4 is lifted to more than half the height of the connecting frame 3, the drone is about to enter the take-off position, and the rack rack 71 is When the lifting assembly 5 is controlled, the rack 4 starts to slide downward and reset. At this time, with the cooperation of the rack 71 and the gear 74, the reeled rope 75 will be released, so that the rope 75 returns to the taut state. In summary, the lifting assembly 5 drives the rack 4 to move upward and lift, so that the rack 71 drives the gear 74 to rotate, and the rotation of the gear 74 drives the take-up wheel 73 to rotate, so that the take-up wheel 73 rewinds the rope 75, thereby maintaining the lifting and reinforcement of the rack 4 for a period of time during the upward lifting of the rack 4, making the drone more stable during the ascent.

[0036] like Figure 1 、 Figure 5 and Figure 6As shown, a buffer mechanism 8 is also included, which includes a mounting plate 81, a sleeve rod 82, a sliding rod 83, a spring 84, a fixed seat 85 and a push rod 86.

The upper right side of the mounting plate 81 is rotatably connected to the fixed seat 85, and the lower part of the fixed seat 85 is connected to the push rod 86 for pushing the sliding rod 83. The right side of the push rod 86 is a curved surface structure, and the left side of the push rod 86 is in contact with the right side of the adjacent sliding rod 83.

[0037] The cam 85 is pressed against the bottom edge of the support 83, and the cam 86 is pressed against the bottom edge of the support 83, and the cam 86 is pressed against the bottom edge of the support 83, and the cam 86 is pressed against the bottom edge of the support 83, and the cam 86 is pressed against the bottom edge of the support 83, and the cam 86 is pressed against the bottom edge of the support 83, and the cam 86 is pressed against the bottom edge of the support 83, and the cam 86 is pressed against the bottom edge of the support 83, and the cam 86 is pressed against the bottom edge of the support 83, and the cam 86 is pressed against the bottom edge of the support 83, and the cam 86 is pressed against the bottom edge of the support 83, and the cam 86 is pressed against the bottom edge of the support 83, and the cam 86 is pressed against the bottom edge of the support 83, and the cam 86 is pressed against the bottom edge of the support 83, and the cam 86 is pressed against the bottom edge of the support 83,

[0038] like Figure 1 and Figure 7 As shown, it also includes a support mechanism 9, which includes a fixed frame 91, a fixed oblique frame 92 and a sliding member 93. The lower sides of the front and rear parts of the placement frame 4 are connected to the fixed oblique frame 92 for improving the bearing capacity of the placement frame 4. The outer side of the mounting frame 62 is connected to the fixed frame 91, and the left side of the fixed oblique frame 92 is connected to the sliding member 93. The sliding member 93 is slidably connected to the adjacent fixed frame 91.

[0039] It should be noted that when the placement rack 4 is raised or lowered, it will drive the fixed inclined rack 92 to move synchronously, so that the sliding members 93 all slide along the adjacent fixed racks 91, and during the raising and lowering process of the placement rack 4, the placement rack 4 is supported by the fixed inclined rack 92.

[0040] like Figure 1 and Figure 8As shown, it also includes a bracket mechanism 10, the bracket mechanism 10 includes a second mounting seat 101, an adjusting screw rod 102 and a limiting rod 103, the front and rear upper sides of the base 1 are connected to the second mounting seat 101, the left and right upper sides of the second mounting seat 101 are connected to the limiting rod 103, and the left and right symmetrical limiting rods 103 are slidably connected with the second mounting seat 101, the upper second mounting seat 101 is used to support the mounting plate 81, and the middle upper side of the lower second mounting seat 101 is rotatably connected to the adjusting screw rod 102, the adjusting screw rod 102 is provided with a screw handle, and the adjusting screw rod 102 is threadedly connected to the adjacent upper second mounting seat 101.

[0041] It should be noted that in order to avoid the right part of the mounting plate 81 being in a suspended state without support, the second mounting seat 101 on the upper side is adjusted by rotating the adjusting screw 102, so that the second mounting seat 101 on the upper side can adjust the support position to ensure that the second mounting seat 101 on the upper side can be fitted with the mounting plate 81, thereby achieving the supporting effect on the mounting plate 81.

[0042] like Figure 1 、 Figure 9 and Figure 10 As shown, it also includes a wire pressing mechanism 11, which includes a mounting frame 111 and a pressing member 112. The right side of the first mounting seat 72 is connected to the mounting frame 111, and the mounting frame 111 is slidably connected to the pressing member 112 for pressing the adjacent pull rope 75.

[0043] It should be noted that by sliding the pressing member 112 to squeeze the adjacent pull ropes 75, the corresponding pull ropes 75 can always be kept taut, preventing the pull ropes 75 from loosening due to unexpected reasons, resulting in a weakening of the pulling and reinforcing ability of the placement rack 4.
