Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an anti-collision unmanned aerial vehicle for teaching. Background Art

[0002] A teaching anti-collision UAV refers to a UAV specially used for teaching purposes and equipped with an anti-collision function, which is used to improve the proficiency of beginners in operating UAVs. However, existing anti-collision UAVs have certain drawbacks. For example, a teaching anti-collision UAV recorded in publication number CN214451818U includes a fuselage and a plurality of wings, wherein the plurality of wings are fixedly connected to the fuselage and are provided with rotors, a support frame is fixedly provided on the top of the fuselage, the support frame is provided with support rods corresponding to the wings, the length of the support rod is greater than the length of the wing, and a protective plate is hingedly provided at one end of the support rod away from the fuselage, and the hinge axis of the protective plate is distributed in the horizontal direction;

[0003] Although the above-mentioned device can transfer the impact force when a collision occurs during the flight of the drone and protect the drone from damage, the protective component lacks a quick-release structure, which makes it impossible to quickly replace the protective component when it is damaged. In addition, the protective component is too complicated, with a large number of spring components used between single components, and a lack of damping parts between some springs, which causes the spring to continue to shake and affects the use effect of the device. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-collision drone for teaching, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A collision-avoiding drone for teaching comprises a drone body, wherein a first mounting frame is nested and connected to the outer surface of the drone body, a second mounting frame is nested and connected to the outer surface of the drone body, connecting ears are fixedly connected to the outer surfaces of the first mounting frame and the second mounting frame, a buffer cylinder is hingedly connected to the outer surface of the connecting ear, a piston is slidably connected to the inside of the buffer cylinder, the outer surface of the piston is embedded and connected to two brackets, a spring is placed inside the buffer cylinder, an inner rod is slidably connected to the inside of the buffer cylinder, and the number of the buffer cylinders is four.

[0007] Furthermore, two ends of the No. 1 mounting frame are fixedly connected with a No. 2 fixing plate, and two ends of the No. 2 mounting frame are fixedly connected with a No. 1 fixing plate. Studs are embedded and connected on the outer surfaces of the No. 1 fixing plate and the No. 2 fixing plate, and nuts are threadedly connected at both ends of the studs.

[0008] Furthermore, the No. 1 mounting frame and the No. 2 mounting frame are detachably connected to the drone body through nuts and studs.

[0009] Furthermore, one end of the buffer cylinder is fixedly connected to a hinge seat, the hinge seat and the outer surface of the connecting ear are both provided with through holes, a pin is inserted into the through hole, and the buffer cylinder and the No. 1 mounting frame and the No. 2 mounting frame are rotationally connected via the pin.

[0010] Preferably, a through groove is provided on the outer surface of the buffer tube, the bracket is slidably connected to the through groove, and the other end of the buffer tube is threadedly connected to a threaded cover.

[0011] Furthermore, the inner rod passes through the threaded cover, and the inner rod and the threaded cover are slidably connected.

[0012] Furthermore, a bolt is threadedly connected to the outer surface of the articulated seat, one end of the bolt is in contact with two brackets, the other end of the inner rod is fixedly connected to a protective frame, one end of the inner rod and the outer surface of the piston are both nested and connected with a rubber sleeve, one end of the spring is in contact with the piston, and the other end of the spring is in contact with the inner rod.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By removing the two nuts, the No. 1 mounting frame and the No. 2 mounting frame can be separated and removed together with the buffer tube and the inner rod to avoid the damaged device from being connected to the drone body, making it easier to replace the new protective components on the drone body and saving the time required to remove the protective components.

[0015] 2. Through the provided buffer cylinder, the buffer cylinder cooperates with the hinge seat and the connecting ear to swing on the No. 1 mounting frame or the No. 2 mounting frame. When the external force is not consistent with the expansion and contraction direction of the buffer cylinder, the buffer cylinder can swing. On the basis of the swing of the buffer cylinder, the piston moves along the inner wall of the buffer cylinder to make the piston squeeze the spring and absorb the external force through the spring. When the external force is consistent with the expansion and contraction direction of the buffer cylinder, the inner rod squeezes the spring and absorbs the external force through the spring. At the same time, the rubber sleeve increases the damping between the inner rod and the piston and the buffer cylinder to avoid repeated swinging of the spring. The spring can absorb forces from different directions, simplifying the buffer structure while ensuring the buffer effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Specifically, when in use, the device is nested in the outer surface of the drone body 1 through the No. 1 mounting frame 2 and the No. 2 mounting frame 201, the inner rod 6 cooperates with the protective frame 601 to protect the drone body 1 to prevent the rotor from being hit by the outside world, and the buffer cylinder 3 is used to absorb the external impact force.

[0024] Embodiment 1

[0025] like Figure 1 As shown, both ends of the No. 1 mounting frame 2 are fixedly connected with the No. 2 fixing plate 204, and both ends of the No. 2 mounting frame 201 are fixedly connected with the No. 1 fixing plate 203, and the outer surfaces of the No. 1 fixing plate 203 and the No. 2 fixing plate 204 are embedded with studs 202, and both ends of the studs 202 are threadedly connected with nuts 205, and the No. 1 mounting frame 2 and the No. 2 mounting frame 201 are detachably connected to the drone body 1 through the nuts 205 and the studs 202.

[0026] In this embodiment, the No. 1 mounting frame 2 and the No. 2 mounting frame 201 can be separated by removing the two nuts 205, and the buffer tube 3 and the inner rod 6 can be removed together to avoid the damaged device from being connected to the drone body 1, making it easier to replace the new protective components of the drone body 1 and saving the time required for disassembling the protective components.

[0027] Embodiment 2

[0028] On the basis of the first embodiment, in order to make up for the problem that the first embodiment does not absorb the external force.

[0029] like Figure 4 As shown, one end of the buffer cylinder 3 is fixedly connected to a hinge seat 301, and the outer surfaces of the hinge seat 301 and the connecting ear 206 are provided with through holes, and a pin shaft 302 is inserted into the through hole. The buffer cylinder 3 and the No. 1 mounting frame 2 and the No. 2 mounting frame 201 are rotatably connected through the pin shaft 302.

[0030] In this embodiment, the buffer tube 3 cooperates with the hinge seat 301 and the connecting ear 206 to swing on the first installation frame 2 or the second installation frame 201. When the external force is not consistent with the expansion and contraction direction of the buffer tube 3, the buffer tube 3 can swing.

[0031] like Figure 3 As shown, a through groove 303 is formed on the outer surface of the buffer tube 3, the bracket 401 is slidably connected to the through groove 303, and a threaded cover 304 is threadedly connected to the other end of the buffer tube 3.

[0032] In this embodiment, the through groove 303 limits the movement of the bracket 401, and the bracket 401 is arranged at an angle. After the buffer cylinder 3 swings, one end of the bracket 401 contacts the No. 1 mounting frame 2 or the No. 2 mounting frame 201, and applies an outward force to the piston 4, so that the piston 4 slides inside the buffer cylinder 3.

[0033] like Figure 4 As shown, the inner rod 6 passes through the threaded cover 304, and the inner rod 6 and the threaded cover 304 are slidably connected.

[0034] In this embodiment, the threaded cover 304 limits the movement of the inner rod 6 and simultaneously installs the inner rod 6 and the spring 5 to achieve a detachable connection between the inner rod 6 and the spring 5 and the buffer tube 3 .

[0035] like Figure 4 As shown, the outer surface of the hinged seat 301 is threadedly connected with a bolt 402, one end of the bolt 402 is in contact with the two brackets 401, the other end of the inner rod 6 is fixedly connected with a protective frame 601, one end of the inner rod 6 and the outer surface of the piston 4 are nested and connected with a rubber sleeve, one end of the spring 5 is in contact with the piston 4, and the other end of the spring 5 is in contact with the inner rod 6.

[0036] In this embodiment, on the basis of the swing of the buffer cylinder 3, the piston 4 moves along the inner wall of the buffer cylinder 3, so that the piston 4 squeezes the spring 5 and absorbs the external force through the spring 5. When the external force is consistent with the expansion and contraction direction of the buffer cylinder 3, the inner rod 6 squeezes the spring 5 and absorbs the external force through the spring 5. At the same time, the rubber sleeve increases the damping between the inner rod 6 and the piston 4 and the buffer cylinder 3 to prevent the spring 5 from swinging repeatedly. That is, the spring 5 can absorb the forces from different directions, simplifying the buffer structure while ensuring the buffer effect.
