Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle (UAV) recovery, and in particular to a damage-resistant and self-depressurizing fixed-wing UAV recovery device. Background Art

[0002] Drones have received widespread attention due to their advantages such as small size, low cost and flexible use. They can be used as platforms in different fields. Among them, fixed-wing drones have the characteristics of fast flight speed, long endurance and high maneuverability. They have been widely used in various industries and directions such as military, reconnaissance and civil. However, there are currently few forms of fixed-wing drone recovery, and the recovery process can easily cause damage to the drone, which brings serious restrictions to the use of fixed-wing drones. Utility Model Content

[0003] The purpose of this utility model is to provide a reasonably designed, easy-to-use, damage-resistant, self-decompression fixed-wing UAV recovery device to address the defects and shortcomings of the existing technology, which can effectively solve the defects of the above-mentioned existing technology.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions: it comprises a recycling box and a partition plate, wherein a plurality of partition plates are fixedly arranged at equal intervals from top to bottom inside the recycling box; it also comprises:

[0005] There are several limit bars, and two of them are symmetrically arranged on the upper side of the partition plate. The limit bars are connected to the side wall of the recycling box through an adjustment mechanism;

[0006] Support plates, wherein there are several support plates, and two of them are symmetrically suspended on the upper side of the partition plate, and the support plates are matched with the inner wall of the recycling box to be in contact with each other;

[0007] There are several extrusion airbags, and they are symmetrically arranged on the upper sides of several support plates. The extrusion airbags are respectively fixed to the lower side walls of the support plates and the partition plates. The uppermost extrusion airbag is fixed to the inner top wall of the recycling box. The extrusion airbag has a built-in air pressure detection sensor;

[0008] There are several rotating rods, and each of them is screwed to the lower surface of the support plate through a hinge seat. After the other end of the rotating rod is tilted downward, a connecting rod is screwed to it through a shaft. The hinge seat on the lower end of the connecting rod is slidably set in a slide groove on the upper surface of the corresponding partition plate;

[0009] There are several bidirectional screw rods, and they are symmetrically embedded in pairs and screwed into the partition plate through bearings. The bidirectional screw rods are screwed into the hinge seat at the lower end of the corresponding connecting rod through threads. The two bidirectional screw rods in the same partition plate are connected by a synchronous wheel transmission assembly. A drive motor is embedded on one side of the interior of the partition plate. The drive motor is fixedly connected to one end of one of the bidirectional screw rods inside the partition plate.

[0010] Through the above technical solution, according to the distance between the two wheels of the rear landing gear of the fixed-wing UAV, the distance between the limit bars on both sides is adjusted by the adjustment mechanism, and then according to the height of the wing, the corresponding drive motor is started, and the drive motor drives the bidirectional screw rod to rotate, and the bidirectional screw rod drives the other bidirectional screw rod connected to it to rotate through the synchronous wheel transmission assembly. The two bidirectional screw rods respectively drive the lower end of the corresponding connecting rod to move, and the upper end of the connecting rod drives the lower end of the rotating rod to rotate, so that the upper end of the rotating rod drives the support plate to move up and down until the support plate moves to a suitable height, and the fixed-wing UAV enters. When recycling the box, the fixed-wing drone enters the upper side of the partition. At this time, the wheels on the rear landing gear of the fixed-wing drone are located between the two limit bars. At the same time, the wings of the fixed-wing drone are located on the upper side of the support plate, and the wings are located between the two corresponding squeezing airbags. The squeezing airbags are then inflated so that the squeezing airbags are squeezed on the upper and lower sides of the wings, thereby fixing the fixed-wing drone. During storage, if shaking occurs and the air pressure in the squeezing airbag changes, the air pressure detection sensor in the squeezing airbag controls the inflation and deflating of the squeezing airbag to avoid damage to the wings.

[0013] A linkage rod, the linkage rod is embedded in the rear side wall of the recycling box and is screwed to the side wall through a bearing. The two ends of the linkage rod are respectively connected to the two internal threaded tubes on the rear side through a synchronous wheel transmission assembly. An adjustment motor is fixed to one end of the linkage rod. The adjustment motor is embedded in and fixed to the side wall of the recycling box.

[0014] Through the above technical solution, the adjusting motor is started, and the adjusting motor drives the linkage rod to rotate. The linkage rod drives the internal threaded tube on the rear side to rotate through the synchronous wheel transmission assembly. The internal threaded tube on the rear side drives the internal threaded tube on the front side to rotate through the synchronous wheel transmission assembly. The internal threaded tubes drive the adjusting screws inside each of them to move, and the adjusting screws drive the limit stop bar to move, thereby adjusting the position of the limit stop bar.

[0015] As a further improvement of the present invention, a sliding block is fixed symmetrically on the side wall of the support plate away from the center of the partition plate, and the sliding block is slidably arranged in a slide groove on the inner wall of the recycling box;

[0016] The above technical solution can increase the stability of the support plate when it moves up and down.

[0017] As a further improvement of the present invention, an arc-shaped contact plate is suspended on the upper side of each partition plate, and a plurality of contact springs are equidistantly arranged on both sides of the outer arc-shaped wall of the arc-shaped contact plate, and the top end of the contact spring is fixed to the bottom wall of the adjacent upper partition plate and the inner top wall of the recycling box;

[0018] Through the above technical solution, the fuselage of the fixed-wing UAV can be limited by the arc-shaped resistance plate.

[0019] As a further improvement of the present invention, a baffle is embedded on the front side of the upper surface of the partition plate, and moving blocks are screwed to both sides of the baffle through a shaft, and the moving blocks are slidably arranged in the moving grooves on the two inner walls of the recycling box, and a limit rod is inserted in both sides of the baffle, and the limit rod is set in an "L" shape. The inner end of the support rod on the rear side of the limit rod is fixedly connected to the inner wall of the partition plate by a return spring, and the outer end of the support rod on the rear side of the limit rod passes through the partition plate and is matched with the limiting hole on the inner wall of the recycling box. The support rod on the front side of the limit rod is movably arranged in the strip groove on the front side wall of the partition plate;

[0020] Through the above technical solution, after the fixed-wing UAV is placed on the partition plate, the baffle is rotated upward while the lower side of the baffle drives the moving block to move forward until the moving block hits the front inner wall of the moving groove. The baffle and the partition plate are in a vertical state. At this time, the limit rod moves toward one side of the inner wall of the recovery box under the elastic force of the return spring until the limit rod is inserted into the corresponding limit hole, thereby limiting the baffle, and the baffle limits the fixed-wing UAV.

[0021] Compared with the existing technology, the beneficial effects of the present invention are as follows: the anti-damage self-decompression fixed-wing UAV recovery device described in the present invention can position the two wheels and wings of the rear landing gear of the fixed-wing UAV respectively, and after positioning, it can automatically release pressure to avoid damage to the wings caused by excessive pressure.
