[0001] The present invention relates to the technical field of unmanned aerial vehicle (UAV) landing gear, and in particular to a vehicle-mounted UAV landing gear that can be flexibly positioned. Background Art

[0002] The landing gear of a drone refers to the structure that supports and takes off and lands the drone. The landing gear supports the entire structure of the drone and is responsible for bearing the static load on the ground and the dynamic load during flight. At the same time, it enables the drone to take off and land safely on the ground. Existing drone landing gear is generally fixed, making it difficult to adjust the angle and fold it, which can easily cause the gimbal's field of view to be affected by the landing gear.

[0003] Therefore, in order to solve the above problems, a vehicle-mounted UAV landing gear with flexible positioning that can fold the landing gear and avoid obstruction of the gimbal's field of view is now developed. Summary of the Invention

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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.

[0028] A vehicle-mounted UAV landing gear with flexible positioning, such as Figure 1 and Figure 2As shown, it includes a mounting plate 1, a folding mechanism 4 and a telescopic mechanism 5. Mounting holes 2 are provided on the four corners of the mounting plate 1. A gimbal hole 3 for positioning the UAV gimbal is provided in the middle of the mounting plate 1. The inner sides of the gimbal holes 3 are all curved structures to avoid damage and scratches to the UAV gimbal. The mounting plate 1 is provided with a folding mechanism 4 for automatically folding, unfolding and adjusting the UAV landing gear. The folding mechanism 4 is provided with a telescopic mechanism 5 for overall adjustment and support of the UAV.

[0029] It should be noted that this device is installed on the bottom of the drone, and the gimbal is aligned with the gimbal hole 3 to complete the positioning. After the positioning process is completed, the bolt is inserted into the mounting hole 2 to complete the fixed connection between the mounting plate 1 and the drone, thereby achieving the effect of overall support for the drone. The telescopic mechanism 5 is in contact with the ground, and the telescopic mechanism 5 is adjusted according to the ground conditions to achieve the effect of adaptive support. When the drone needs to take off, the folding mechanism 4 is controlled to operate so that the landing gear is unfolded to avoid the landing gear blocking the gimbal's field of view.

[0030] like Figure 1 and Figure 3 As shown, the folding mechanism 4 includes a fixed seat 41, a rotating member 42, a bevel gear set 43 and a dual-axis motor 44. The lower sides of the front and rear parts of the mounting plate 1 are connected to the fixed seat 41 by bolts. The rotating member 42 is rotatably connected to the fixed seat 41. The lower left side of the mounting plate 1 is connected to the dual-axis motor 44 by bolts. The output shaft of the dual-axis motor 44 is arranged in a front-to-rear direction. A bevel gear set 43 is connected between the left side of the rotating member 42 and the adjacent output shaft of the dual-axis motor 44. The bevel gear set 43 is composed of two bevel gears of the same specification. A bevel gear is connected to the left side of the rotating member 42, and another bevel gear is connected to the output shaft of the dual-axis motor 44. The adjacent bevel gears are meshed with each other.

[0031] It should be noted that when the UAV needs to take off, the output shaft of the dual-axis motor 44 is controlled to rotate. The rotation of the output shaft of the dual-axis motor 44 will drive the bevel gear set 43 to enter a rotating state, so that the rotating parts 42 start to rotate and lift, thereby achieving the effect of folding the landing gear, avoiding the landing gear from blocking the field of view of the gimbal, and at the same time reducing the overall thickness of the UAV to avoid affecting the flight operation of the UAV. In summary, by controlling the rotation of the output shaft of the dual-axis motor 44, the bevel gear set 43 drives the rotating part 42 to rotate synchronously, so that the landing gear as a whole can be flipped and folded, avoiding the landing gear from blocking the field of view of the gimbal.

[0032] like Figure 1 and Figure 4As shown, a telescopic mechanism 5 is also included, and the telescopic mechanism 5 includes a first telescopic rod 51, a cross bar 52, an electric push rod 53 and a connecting member 54. The rotating member 42 is connected to the first telescopic rod 51, and the bottom end of the first telescopic rod 51 is connected to the cross bar 52 for overall support. Two connecting members 54 are connected to the outside of the first telescopic rod 51, and electric push rods 53 are connected between adjacent connecting members 54. The telescopic end of the electric push rod 53 is connected to the adjacent cross bar 52.

[0033] It should be noted that when the UAV is in a ground state, the overall side support function is completed by relying on the contact between the cross bar 52 and the ground. At the same time, during the support process, due to different ground conditions, different heights are likely to occur. At this time, in order to improve the placement stability, the electric push rod 53 can be controlled to operate, so that the telescopic end of the electric push rod 53 is extended, and then the cross bar 52 is pushed downward, so that the position of the cross bar 52 can be adapted to the ground, thereby enhancing the support stability of the UAV. In summary, by adjusting the extension of the telescopic end of the electric push rod 53, the telescopic end of the electric push rod 53 can push the corresponding cross bar 52 to move, so that the cross bar 52 can adapt to different ground conditions, thereby improving the stability of the cross bar 52 during support.

[0034] like Figure 1 and Figure 5 As shown, a stabilizing mechanism 6 is also included, and the stabilizing mechanism 6 includes a fixing frame 61, a guide frame 62 and a stabilizing rod 63. The lower right side of the mounting plate 1 is connected to the front and rear symmetrical fixing frames 61, and the right side of the connecting member 54 is connected to the stabilizing rod 63. The fixing frames 61 are connected to the guide frames 62 for guiding the movement of the stabilizing rod 63 by bolts, and the stabilizing rod 63 is slidably connected to the adjacent guide frames 62.

[0035] It should be noted that when the rotating member 42 starts to rotate and drives the first telescopic rod 51 to move, the connecting member 54 will move synchronously with the first telescopic rod 51, so that the stabilizing rod 63 will move along the guide frame 62, so that the first telescopic rod 51 can move and unfold stably, thereby improving the stability of the movement of the first telescopic rod 51 and avoiding the first telescopic rod 51 from shaking during the movement. In summary, the stabilizing rod 63 is slidably guided by the guide frame 62, so that the first telescopic rod 51 can slide stably when moving and unfolding, avoiding the first telescopic rod 51 from shaking violently when unfolding, and improving the stability of the first telescopic rod 51 when unfolding.

[0036] like Figure 1 and Figure 6As shown, a buffer mechanism 7 is also included, which includes a connecting ring 71, a second telescopic rod 72, a spring 73 and a buffer plate 74. Four connecting rings 71 are connected to the cross bar 52, and the bottom of the connecting ring 71 is connected to the second telescopic rod 72. Buffer plates 74 for buffering the landing of the drone are connected between the bottom ends of adjacent second telescopic rods 72. Four springs 73 are connected between the buffer plates 74 and the adjacent cross bars 52. The buffer plates 74 are all curved structures, which can improve the buffering effect of impact force. The bottom of the buffer plates 74 are connected with anti-slip strips, which can increase the friction between the buffer plates 74 and the ground.

[0037] It should be noted that after the drone takes off, it will start to fly back to the ground. When the drone touches the ground, the bottom of the buffer plate 74 will touch the ground. As a result, under the squeezing effect of the drone's gravity, the buffer plate 74 will push the second telescopic rod 72 to contract, and then the spring 73 will be compressed, thereby achieving the effect of buffering the impact force of the drone's landing, and avoiding the impact of the drone's direct landing on the internal parts.

[0038] like Figure 1 and Figure 7 As shown, it also includes a counterweight mechanism 8, which includes a fixing part 81, a screw rod 82 and a counterweight block 83. The fixing part 81 is connected to the lower right side of the mounting plate 1, and the screw rod 82 is connected to the fixing part 81. The front and rear parts of the screw rod 82 are both threadedly connected to the counterweight block 83 for balancing the weight of the drone.

[0039] It should be noted that when the UAV is taking off, in order to ensure the smooth flight of the UAV, the overall balance of the UAV needs to be maintained. At this time, the counterweight block 83 can be added according to the weight of the dual-axis motor 44, so that the counterweight block 83 is threadedly connected to the screw rod 82, thereby achieving the effect of increasing the counterweight and thus achieving the effect of overall balance of the UAV.

[0040] like Figure 1 and Figure 8 As shown, it also includes a fixing mechanism 9, which includes a sliding rod 91, a protrusion 92 and an insertion rod 93. The left and right parts of the cross bar 52 are both slidably connected to the sliding rod 91, and the upper side of the sliding rod 91 is connected to a protrusion 92 for easy manipulation. The outer side of the sliding rod 91 is rotatably connected to an insertion rod 93 for inserting into the ground, and the bottom end of the insertion rod 93 is a conical structure.

[0041] It should be noted that when the UAV takes off, it is necessary to rotate the insertion rods 93 to a state parallel to the sliding rods 91. When they are completely parallel, the protrusions 92 are pushed inward so that the sliding rods 91 drive the adjacent insertion rods 93 to be retracted into the cross bar 52, completing the quick storage and preventing the expansion of the insertion rods 93 from affecting the normal flight of the UAV. Similarly, when the UAV lands on the ground, the protrusions 92 are pushed so that the sliding rods 91 drive the insertion rods 93 to slide out, and then the insertion rods 93 are flipped over and inserted into the soil to complete the fixation of the UAV.

[0042] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications may be made to the present invention without departing from the principles and spirit of the invention as defined in the claims. Therefore, the detailed description of the disclosed embodiments is intended to be illustrative only and not to limit the present invention, which is to be defined by the claims.
