DETAILED DESCRIPTION

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] A vehicle-mounted UAV landing gear sliding adjustment and positioning device, such as Figure 1 As shown, it includes base plates 1, 1 and 2, a sliding member 2 is slidably connected to the base plate 1, the upper part of the sliding member 2 is rotatably connected to a mounting plate 3, the upper left side of the mounting plate 3 is rotatably connected to a placement plate 4 for placing and supporting the drone, and the sliding member 2 is provided with an adjustment mechanism 5 for adjusting the placement plate 4 at multiple angles.

[0030] It should be noted that after the drone takes off, it needs to return to the original take-off position. However, for existing drones to land, it is difficult to return to the initial position accurately. Therefore, when the drone is landing, this device can be used to receive the drone. First, the sliding part 2 sliding on the bottom plate 1 is used to adjust the overall position of the placement plate 4. Then, the adjustment mechanism 5 is controlled to operate according to the landing state of the drone, so that the adjustment mechanism 5 drives the placement plate 4 to perform corresponding rotation adjustment, so that the position of the placement plate 4 can match the final landing position of the drone, thereby achieving the effect of automatically adjusting the receiving position.

[0031] like Figure 1-Figure 3 As shown, the adjusting mechanism 5 includes a gear 51, a rotating shaft 52 is rotatably connected to the left part of the mounting plate 3, and a driving motor 53 is connected to the right part of the mounting plate 3. The output shaft of the driving motor 53 is set to face downward. There are four gears 51, two of which are fixedly mounted on the sliding member 2 and the placement plate 4 respectively, and the other two gears 51 are respectively mounted on the rotating shaft 52 and the output shaft of the driving motor 53. A pulley assembly 54 is connected between the rotating shaft 52 and the output shaft of the driving motor 53. The pulley assembly 54 includes two pulleys and a transmission belt. Pulleys are connected to the lower part of the rotating shaft 52 and the output shaft of the driving motor 53, and a transmission belt is wound around the pulleys.

[0032] It should be noted that when the drone is landing, in order to ensure that the placement plate 4 can be accurately aligned with the final landing point of the drone, the drive motor 53 can be controlled so that the output shaft of the drive motor 53 starts to rotate, thereby causing the output shaft of the drive motor 53 to drive the pulley assembly 54 to operate. At this time, the two gears 51 on the right will begin to interact with each other, so that the mounting plate 3 starts to move in a circular motion with the sliding member 2 as the center. At the same time, under the action of the pulley assembly 54, the two gears 51 on the left will also begin to interact with each other, so that the placement plate 4 rotates accordingly. During this rotation process, the placement plate 4 can always remain relatively stationary, so that the display angle of the placement plate 4 will not change, which is convenient for matching and docking with the landing point of the drone.

[0033] like Figure 1 and Figure 4 As shown, the mobile mechanism 6 is also included. The mobile mechanism 6 includes a landing gear 61. The landing gear 61 is placed on the placement plate 4. The four parts of the landing gear 61, front, back, left, and right, are connected to distance sensors 62 for sensing distance data. Corresponding convex plates are also provided at corresponding positions on the placement plate 4. The front and back parts of the landing gear 61 are connected to four left-right symmetrical first fixing members 63. The first fixing members 63 are rotatably connected to a moving rod 65 for assisting the landing gear 61 to move. The moving rod 65 is connected to the adjacent first fixing member 63. The rotating assembly 64 and the front and rear sides of the landing gear 61 are connected with left-right symmetrical second fixing parts 66, and the second fixing parts 66 are located on the outside of the adjacent first fixing parts 63. The front and rear symmetrical second fixing parts 66 are also rotatably connected with a moving rod 65, and the moving rod 65 and the adjacent second fixing parts 66 are also connected with a rotating assembly 64. The rotating assembly 64 includes a motor and a transmission wheel. The motor is installed on the inner side of the first fixing part 63 by means of a connecting plate, and the corresponding positions of the motor output shaft and the moving rod 65 are connected with mutually meshing transmission wheels.

[0034] It should be noted that the landing gear 61 is directly installed on the drone. After the drone completes landing, the distance sensor 62 is used to detect the corresponding protruding plate on the placement plate 4 to calculate whether the drone landing gear 61 is in the correct position. When the distance sensor 62 detects that there is a certain error in the data information, the distance sensors 62 on the left and right sides will correspondingly start the rotating components 64 on the first fixing part 63, and the sensors on the front and rear sides will correspondingly start the rotating components 64 on the second fixing part 66. After the rotating components 64 on the first fixing part 63 are started, they will drive the front and rear moving rods 65 to rotate, thereby causing the landing gear 61 to move in the left and right directions. After the transmission components on the second fixing part 66 are started, they will drive the left and right moving rods 65 to rotate, thereby causing the landing gear 61 to move in the front and rear directions. In this way, the final position of the landing gear 61 is automatically adjusted so that the landing gear 61 can be located in the correct parking position, thereby improving the convenience of operation.

[0035] Example 2

[0036] On the basis of Example 1, Figure 1 and Figure 5 As shown, it also includes a return mechanism 7, which includes a drive motor 71. The drive motor 71 is connected to the lower left side of the base plate 1 by bolts. The output shaft of the drive motor 71 is set to face right. The output shaft of the drive motor 71 is connected to a screw rod 72. The lower side and the right side of the base plate 1 are both connected to a bearing seat 73. The screw rod 72 is rotatably connected to the bearing seat 73, and the screw rod 72 is threadedly connected to the sliding member 2. The left and right parts of the screw rod 72 are both provided with limit rings for limiting the sliding member 2.

[0037] It should be noted that when the drone operation is completed, in order to effectively store the placement plate 4, the drive motor 71 can be started. The rotation of the output shaft of the drive motor 71 will drive the screw 72 to rotate, so that the sliding member 2 slides along the bottom plate 1, thereby achieving the effect of driving the placement plate 4 back to the original position.

[0038] like Figure 1 and Figure 6 As shown, an anti-skid mechanism 8 is also included, and the anti-skid mechanism 8 includes a rotating frame 81. The left and right parts of the landing gear 61 are rotatably connected to the rotating frame 81. The left and right parts of the landing gear 61 are correspondingly connected to fixed rings 82. The fixed rings 82 are located in front of adjacent rotating frames 81. Torsion springs 83 are connected between the rotating frames 81 and the adjacent fixed rings 82. Two left-right symmetrical conical parts 85 are connected to the placement plate 4, and the rotating frames 81 are connected to fixed columns 84 pushed by adjacent conical parts 85.

[0039] It should be noted that when the drone drives the landing gear 61 to stop on the placement plate 4, the position of the landing gear 61 may not be the exact position at this time, so the landing gear 61 will start to automatically adjust its position. During the adjustment process, the fixed column 84 will be affected by the adjacent conical part 85, thereby causing the rotating frame 81 to begin to flip outward, and the torsion spring 83 will be deformed under force, thereby causing the outer side of the rotating frame 81 to contact the placement plate 4, increasing the friction between the landing gear 61 and the placement plate 4, and preventing the drone from accidentally sliding after docking.

[0040] like Figure 1 and Figure 7 As shown, it also includes a support mechanism 9, which includes a support frame 91. The support frame 91 is connected to the mounting plate 3, and two rolling rods 92 in contact with the base plate 1 are rotatably connected to the front and rear sides of the support frame 91.

[0041] It should be noted that as the mounting plate 3 begins to move in a circle with the sliding member 2 as the center, the support frame 91 will drive the rolling rod 92 to move continuously, so that the rolling rod 92 can continuously adjust the contact position with the base plate 1, so that the mounting plate 3 can always be supported, thereby improving the load-bearing stability of the mounting plate 3.

[0042] like Figure 1 and Figure 8 As shown, a blocking component 10 is also included, and each rotating component 64 is connected to a blocking component 10 for dust protection.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
