DETAILED DESCRIPTION

[0024] In order to make the purpose and the advantage of the utility model more clear and obvious, the utility model is specifically explained below in combination with examples.It should be understood that the following text is only used to describe one or several specific implementation modes of the utility model, and does not strictly limit the protection scope specifically requested by the utility model.

[0025] As Figures 1 to 4 shown, an unmanned aerial vehicle anti-collision mechanism, including body 1, body 1 four corners are provided with connecting arm 2, connecting arm 2 other end is provided with anti-collision block 3, anti-collision block 3 other end is provided with multiple groups of connecting support 4, connecting support 4 other end is provided with anti-collision plate 5, connecting arm 2 away from body 1 one end is provided with first anti-collision device 6 and second anti-collision device 7 respectively;

[0026] Among them, first anti-collision device 6 and second anti-collision device 7 are used for buffering the impact force generated by the collision of body 1 respectively.

[0027] In this embodiment, when the body 1 collides with the obstacle, the impact force is generated by the collision between the anti-collision plate 5 and the obstacle, the impact force is generated on the body 1 by the connecting bracket 4 and the anti-collision block 3, the body 1 continues to move towards the obstacle, so that the anti-collision block 3 moves along the through hole 202 in the connecting arm 2 at this time. Due to the movement of the anti-collision block 3, the slider 601 in the first anti-collision device 6 moves along with the anti-collision block 3, and at this time the slider 601 on the first slide rod 602 moves inwards along the sliding groove 203, thereby extruding the first spring 603, so that a part of the impact force is converted into the elastic potential energy of the first spring 603; at the same time, due to the movement of the anti-collision block 3, the connecting rod 701 in the second anti-collision device 7 rotates with the movement of the anti-collision block 3, so that the other end of the connecting rod 701 rotates around the moving block 702, thereby enabling the moving block 702 to slide on the second slide rod 703 and extrude the second spring 704 on the second slide rod 703. At this time, the impact force generated by the collision is converted into the elastic potential energy of the second spring 704. Through the action of the double anti-collision device, the unmanned aerial vehicle body 1 and the propeller can be better protected, and damage to the unmanned aerial vehicle body 1 and the propeller during collision can be prevented, thereby effectively improving the service life of the unmanned aerial vehicle, and a series of work is completed.

[0028] As shown in Figure 4 The first anti-collision device 6 includes a slider 601, the anti-collision block 3 is fixedly connected to the slider 601 on both sides, the slider 601 is slidably connected with a first slide rod 602, the slider 601 is fixedly connected with a first spring 603 on one side, the other end of the first spring 603 is fixedly connected with the connecting arm 2, and the first slide rod 602 is arranged at the center axis of the first spring 603. The first slide rod 602 is fixedly connected with the connecting arm 2 at both ends.

[0029] In the above manner, when a collision occurs, due to the movement of the anti-collision block 3, the slider 601 in the first anti-collision device 6 moves along with the anti-collision block 3, at this time the slider 601 on the first slide rod 602 moves inwards along the sliding groove 203, and extrudes the first spring 603 on the first slide rod 602, so that a part of the impact force is converted into the elastic potential energy of the first spring 603;

[0030] And when the collision is over, the first anti-collision device 6 can be restored to the initial state by the elastic characteristics of the first spring 603.

[0031] As shown in Figure 4 And Figure 5As shown, the second anti-collision device 7 includes two groups of connecting rods 701, and one end of each group of connecting rods 701 is rotatably connected to the inner side of the anti-collision block 3. The other end of the connecting rod 701 is rotatably connected with a moving block 702. The moving block 702 is slidably connected with a second slide rod 703. The moving block 702 is fixedly connected with a second spring 704 on one side. The other end of the second spring 704 is fixedly connected with the connecting arm 2. The second slide rod 703 is arranged at the central axis of the second spring 704. The two ends of the second slide rod 703 are fixedly connected with the connecting arm 2.

[0032] In the above manner, when a collision occurs, the connecting rod 701 in the second anti-collision device 7 rotates with the movement of the anti-collision block 3, so that the other end of the connecting rod 701 rotates around the moving block 702, so that the moving block 702 can slide on the second slide rod 703 and press the second spring 704 on the second slide rod 703. At this time, the impact force generated by the collision is converted into the elastic potential energy of the second spring 704.

[0033] As shown in Figure 6 The end of the connecting arm 2 away from the body 1 is provided with a rectangular groove 201. The outer side of the rectangular groove 201 is provided with a through hole 202. The two sides of the end of the rectangular groove 201 away from the body 1 are respectively provided with a sliding groove 203.

[0034] As shown in Figure 4 and Figure 5 The through hole 202 and the rectangular groove 201 are respectively matched with the anti-collision block 3. The sliding block 601, the first slide rod 602 and the first spring 603 are respectively arranged in the sliding groove 203, and the sliding groove 203 is matched with the sliding block 601. The connecting rod 701, the moving block 702, the second slide rod 703 and the second spring 704 are respectively arranged in the inner side of the rectangular groove 201, and the moving block 702 is matched with the rectangular groove 201.

[0035] In the above manner, when a collision occurs, the sliding block 601 on the first slide rod 602 in the first anti-collision device 6 moves along the sliding groove 203 and presses the first spring 603 in the sliding groove 203, so that part of the impact force generated by the collision is converted into the elastic potential energy of the first spring 603. At the same time, the second anti-collision device 7 works in the rectangular groove 201. The connecting rod 701 in the second anti-collision device 7 is moved inwardly by the movement of the anti-collision block 3 and rotates around the anti-collision block 3 and the moving block 702, so as to drive the moving block 702 to move on the second slide rod 703, so that the moving block 702 presses the second spring 704 at both ends of the second slide rod 703, and converts part of the impact force generated by the collision into the elastic potential energy of the second spring 704.

[0036] As shown in Figure 3As shown, the anti-collision plate 5 is arc-shaped and hollow in the middle.

[0037] In the above manner, the anti-collision plate 5 is arc-shaped and hollow, so that the anti-collision structure of the unmanned aerial vehicle can reduce weight, thereby prolonging the service life of the unmanned aerial vehicle, and the hollow design can make the anti-collision plate 5 have certain toughness, so as to increase the service life of the anti-collision plate 5 during use.

[0038] The working principle of the utility model is as follows: when the machine body 1 collides, the anti-collision plate 5 collides with the obstacle to generate an impact force, so that the connecting bracket 4 and the anti-collision block 3 generate an impact force on the machine body 1, and the machine body 1 continuously moves towards the obstacle, so that the anti-collision block 3 moves in the connecting arm 2 along the through hole 202 at this time. Due to the movement of the anti-collision block 3, the sliding block 601 in the first anti-collision device 6 moves along with the anti-collision block 3, and at this time, the sliding block 601 on the first sliding rod 602 moves inwards along the sliding groove 203, thereby extruding the first spring 603, so that part of the impact force is converted into the elastic potential energy of the first spring 603. At the same time, due to the movement of the anti-collision block 3, the connecting rod 701 in the second anti-collision device 7 rotates along with the movement of the anti-collision block 3, so that the other end of the connecting rod 701 rotates around the moving block 702, thereby enabling the moving block 702 to slide on the second sliding rod 703 and extrude the second spring 704 on the second sliding rod 703. At this time, the impact force generated by the collision is converted into the elastic potential energy of the second spring 704. Through the action of the double anti-collision devices, the unmanned aerial vehicle body 1 and the propeller can be better protected, so as to prevent damage to the unmanned aerial vehicle body 1 and the propeller during collision, effectively improve the service life of the unmanned aerial vehicle, and complete a series of work.

[0039] The above is only the preferred embodiment of the utility model, and it should be pointed out that for ordinary technical personnel in the technical field, without departing from the principle of the utility model, a number of improvements and refinements can be made, and these improvements and refinements should be regarded as the protection range of the utility model. The structures, devices and operation methods not specifically described and explained in the utility model are implemented according to the conventional means in the field, unless otherwise specified and limited.
