Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of target drones, and particularly relates to a crawler-type moving target drone. Background Art
[0002] In the fields of current military training and shooting drills, the target design and performance of moving target drones play a crucial role in enhancing the training effect and cultivating the actual combat ability of trainees. However, traditional moving target drones have many significant limitations in terms of target design and functions.
[0003] The targets of traditional moving target drones usually can only move along a simple and fixed straight trajectory, or operate according to several preset limited motion modes. This monotonous and unchanging motion method is far from the real and complex postures and motion trajectories of targets on the battlefield. In actual combat scenarios, targets may perform actions such as turning around and squatting, while the straight-line motion of most existing moving target drones in the prior art is difficult to meet the above training requirements.
[0004] It is impossible to realistically simulate these complex and random actions, which makes it difficult for trainees to encounter situations close to actual combat during training, resulting in a huge gap between the training effect and the actual combat requirements.
[0005] In summary, in order to effectively meet the strict requirements of modern military training for high actual combatization and significantly improve the response ability and shooting accuracy of trainees in complex and changeable environments, there is an urgent need to develop an innovative crawler-type moving target drone. Content of the Utility Model

By providing the electric lifting rod 6, the target 2 can be driven to rise or fall to simulate squatting and standing up. By providing the first motor 5 and the rotating seat 4, the target 2 can be driven to rotate by a certain angle, so that the size of the impact surface of the target 2 can be adjusted, thereby simulating different impact surface sizes when side-facing and front-facing. During training, by digging some shallow trenches in the length for the crawler drive base 1 to move, on the one hand, it can be used to simulate trench movement, and on the other hand, it can protect the crawler drive base 1 from being exposed and accidentally injured. The protective plates 7 are used to protect the electric lifting rod 6, the rotating seat 4, etc. Active wheels 34, driven wheels 35, crawlers 36 and a tensioning mechanism 37 for tensioning the crawlers 36 are provided on both sides of the crawler drive base 1.

A single-chip microcomputer and necessary power supply circuits and control circuits are provided inside the control module. The first motor 5 and the second motor 14 are both connected to the battery unit through the control module for control.
[0026] A first installation groove 8 is recessed on the upper side of the fixed seat 3. The first motor 5 is installed in the first installation groove 8, and the output shaft is arranged upward. The lower side of the rotating seat 4 is fixedly connected to the output shaft of the first motor 5 through a drive hole 9. By providing the first installation groove 8, the first motor 5 can be stably installed, so that the first motor 5 can drive the rotating seat 4 to rotate.
[0027] A rotating ring 10 is provided around the first installation groove 8 on the upper side of the fixed seat 3, and a rotating ring 10 groove matching the rotating ring 10 is provided on the lower side of the rotating seat 4. By providing the rotating ring 10 and the rotating ring 10 groove, the rotation of the rotating seat 4 can be made more stable and smooth.

When the lead screw 17 rotates, since the driving block 18 is restricted by the limiting round rod 19 and the semi-circular groove and cannot rotate with the lead screw 17, it can only move up and down along the lead screw 17. When the driving block 18 moves upward, it pushes the lifting section 13 to move upward along the lifting hole 16. When the driving block 18 moves downward, the lifting section 13 moves downward along with the driving block 18 by virtue of its own weight.

A first through hole 29 and a second through hole 30 which are aligned with each other are respectively arranged on the left fixing plate 27 and the right fixing plate. A third through hole 31 penetrating the left and right sides is arranged at a position near the lower end of the protection plate 7. When the lower side of the protection plate 7 is clamped in the fixing groove 26, the first through hole 29, the second through hole 30 and the third through hole 31 are aligned, and the first through hole 29, the second through hole 30 and the third through hole 31 are connected by a fixing bolt 32. When installing the protection plate 7, insert the lower side of the protection plate 7 into the fixing groove 26, and then fix the protection plate 7 in the fixing groove 26 by passing the fixing bolt 32 through the first through hole 29, the third through hole 31 and the second through hole 30 in sequence.
