Description

Technical Field

[0001] The present application relates to the field of target drone technology, and in particular to a device for recovering a target drone and reducing wing surface damage. Background Art

[0002] A target drone is a type of military aircraft used as a target for shooting training. This type of aircraft uses remote control or pre-set flight paths and modes to simulate enemy aircraft or incoming missiles during military exercises or weapon tests, providing imaginary targets and shooting opportunities for various types of artillery or missile systems. It is a type of unmanned aircraft.

[0003] The target drone will be subject to collision and friction during the landing process, which may cause damage to the wing surface of the target drone, thereby reducing the service life of the target drone and increasing maintenance costs.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the wing surface should be protected during the landing of the target drone, so as to increase the service life of the target drone and reduce its maintenance cost. Utility Model Content

[0005] In order to solve the above technical problems, the present application provides a device for recovering a target drone and reducing wing surface damage.

[0006] The present application provides a device for recovering a target drone and reducing wing surface damage, which adopts the following technical solution:

[0007] A device for recovering a target drone and reducing wing surface damage comprises a wing, a connecting ear arranged on the wing root, a connecting plate connected to the connecting ear, and connecting bolts and shear bolts for connecting the connecting ear and the connecting plate; the shear bolt is provided with a first shear groove, and the connecting bolt and the shear bolt are both provided with anti-loosening components at one end close to a nut.

[0008] By adopting the above technical solution, during the landing process of the target drone, when the wing surface is subjected to a large impact force, the shear bolt can be sheared off at the first shear groove, thereby playing a role in kinetic energy absorption and buffering, protecting the wing surface from damage, thereby increasing the service life of the target drone and reducing the maintenance cost of the target drone. At the same time, in order to enhance the stability of the connection and prevent the bolts from loosening, an anti-loosening component is provided at one end of the connecting bolt and the shear bolt close to the nut.

[0009] Preferably, a second shearing groove is formed on the shearing bolt, and the second shearing groove is arranged parallel to the first shearing groove.

[0010] By adopting the above technical solution, the second shearing groove is arranged in parallel with the first shearing groove, so that the shearing bolt has more shearing options when subjected to impact force, thereby flexibly absorbing impact energy.

[0011] Preferably, the first shear groove is located at the center of the screw rod of the shear bolt on one side close to the nut of the shear bolt, the second shear groove is located between the first shear groove and the nut of the shear bolt, and the distance between the second shear groove and the first shear groove is one quarter of the length of the screw rod of the shear bolt.

[0012] By adopting the above technical solution, the position design of the first shear groove and the second shear groove enables the shear bolt to effectively absorb kinetic energy when subjected to different impact forces, thereby achieving buffering and protection of the wing surface through shearing.

[0013] Preferably, the shear bolts are aluminum bolts.

[0014] By adopting the above technical solution, the aluminum bolts have lighter weight and better shearing properties than traditional steel bolts. During the landing of the target drone, the aluminum shear bolts can be more easily broken at the first shear groove and the second shear groove, thereby effectively absorbing the impact energy and reducing the damage to the wing surface.

[0015] Preferably, a polymer wear-resistant coating is provided on the wing surface of the wing.

[0016] By adopting the above technical solution, the provision of the polymer wear-resistant coating improves the wear resistance of the wing surface and reduces the friction damage to the wing surface, thereby increasing the service life of the target drone and reducing the maintenance cost of the target drone.

[0017] Preferably, a limiting hole is provided on the screw rod of the shear bolt, and a limiting slot is provided on the nut of the shear bolt, and the limiting slots are multiple in number, and the anti-loosening component includes a limiting pin inserted in the limiting hole and the limiting slot.

[0018] By adopting the above technical solution, the limit pin cooperates closely with the limit hole and the limit groove, which significantly enhances the stability of the connection between the connecting bolts and the shear bolts, and reduces the phenomenon of loosening of the connecting bolts and the shear bolts due to vibration or impact, thereby ensuring the safety performance of the target drone during the recovery process.

[0019] Preferably, a limiting protrusion is provided at one end of the limiting pin, and a limiting strip is provided at the other end. The limiting strip passes through the limiting hole and the limiting groove corresponding to the limiting hole. The limiting strip is bent and inserted into the limiting groove adjacent to the limiting hole.

[0020] By adopting the above technical solution, the setting of the limiting protrusion and the limiting strip enables the limiting latch to be firmly locked on the shear bolt, thereby improving the anti-loosening effect of the limiting latch.

[0021] Preferably, an anti-skid groove is provided on the nut of the shear bolt, and the number of the anti-skid grooves is multiple, and the multiple anti-skid grooves are evenly distributed on the nut of the shear bolt.

[0022] By adopting the above technical solution, the anti-skid groove increases the friction coefficient of the nut of the shear bolt and provides a better grip. During the installation or removal of the shear bolt, the anti-skid groove can effectively prevent the tool or hand from slipping, thereby improving the convenience and safety of the operation.

[0023] In summary, this application has the following beneficial technical effects:

[0024] 1. The present application adopts an aluminum shear bolt, and a first shear groove and a second shear groove are opened on the bolt, so that when the target aircraft is landing, the wing surface is subjected to force to the connection point, and the shear bolt will be sheared at a specific position, thereby playing the role of kinetic energy absorption, buffering and protection, and effectively protecting the wing surface from damage;

[0025] 2. The present application adopts a polymer wear-resistant layer coated on the wing surface, which improves the wear resistance of the wing, thereby extending the service life of the target drone and reducing the maintenance cost of the target drone;

[0026] 3. The setting of the anti-loosening component reduces the phenomenon of loosening of the connecting bolts and shear bolts due to vibration or impact, thereby ensuring the safety performance of the target drone during the recovery process. BRIEF DESCRIPTION OF THE DRAWINGS

The connecting bolt 3 is threadedly connected to the connecting ear 11 and the connecting plate 2, respectively, and the shear bolt 4 is threadedly connected to the connecting ear 11 and the connecting plate 2, respectively. The shear bolt 4 is provided with a first shearing groove 41 and a second shearing groove 42, the second shearing groove 42 is arranged parallel to the first shearing groove 41, and the first shearing groove 41 and the second shearing groove 42 are parallel to the nut of the shear bolt 4.

The connecting bolt 3 and the shear bolt 4 are both equipped with a gasket 6.

[0034] The first shearing groove 41 is located at the center of the screw rod of the shearing bolt 4 on one side close to the nut of the shearing bolt 4, and the second shearing groove 42 is located between the first shearing groove 41 and the nut of the shearing bolt 4, and the distance between the second shearing groove 42 and the first shearing groove 41 is one quarter of the length of the screw rod of the shearing bolt 4. In the embodiment of the present application, the screw rod of the shearing bolt 4 has a diameter of 5 mm, wherein the diameters of the positions where the first shearing groove 41 and the second shearing groove 42 are opened on the screw rod are both 4.5 mm.

[0035] The shear bolt 4 is an aluminum bolt, and the shear bolt 4 is made of aluminum alloy.

[0036] A limiting hole 43 is provided on the screw rod of the shear bolt 4, and the limiting hole 43 is arranged at the end of the screw rod away from the nut. A limiting groove 44 is provided on the nut of the shear bolt 4, and the number of the limiting grooves 44 is six, and the six limiting grooves 44 are arranged in a circular array, and the six limiting grooves 44 are evenly distributed on the nut of the shear bolt 4.
