[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0027] like Figures 1 to 5 As shown, a rotating retractable mechanism for a drone pod includes a mounting plate 1, a pod body 2 arranged inside the mounting plate 1, a retractable mechanism 31 provided on the mounting plate 1, an auxiliary retractable mechanism 32 provided on the retractable mechanism 31, and the retractable mechanism 31 includes a fixing plate 311 fixedly connected to the outer wall of the mounting plate 1, a motor 312 fixedly connected to the inner outer wall of the fixing plate 311, a screw rod 313 fixedly connected to the output end of the motor 312, a threaded sleeve 314 threadedly connected to the outer wall of the screw rod 313, and a protective cover 31 fixedly connected to the outer wall of the threaded sleeve 314 away from the outer wall of the screw rod 313. 5. A push plate 316 is fixedly connected to the outer wall of one side of the protective cover 315, and a limiting slide groove 317 is provided at the bottom end of the mounting plate 1. The inner wall of the limiting slide groove 317 is slidably connected to the limiting slider 318. The outer wall of the limiting slider 318 is fixedly connected to the outer wall of the protective cover 315. A receiving groove is provided at the bottom end of the mounting plate 1, and a rotating hole is provided on the inner wall of the receiving groove. A torsion spring 319 is fixedly connected to the inner wall of the rotating hole. The torsion spring 319 is fixedly connected to the rotating shaft 3110 at one end away from the inner wall of the rotating hole. The outer wall of the rotating shaft 3110 is rotatably set on the inner wall of the rotating hole, and the outer wall of the rotating shaft 3110 is fixedly connected to the support plate 3111.

[0028] Furthermore, a limiting hole is opened at the bottom end of the mounting plate 1, and the end of the screw rod 313 away from the motor 312 is rotatably connected to the inner wall of the limiting hole through a bearing, and the outer wall of the threaded sleeve 314 is slidably set on the inner wall of the limiting hole and fits in place with the inner wall of the limiting hole, so that the threaded sleeve 314 can be limited by the limiting hole.

[0029] Furthermore, the push plate 316 is made of rubber, so that after the pod body 2 is pushed into the storage groove, it can pass over the pod body 2 due to its flexible properties to ensure that the protective cover 315 can protect and store the pod body 2.

[0030] Furthermore, the inner wall of the rotating hole opened on the inner wall of the receiving groove on the mounting plate 1 fits snugly with the outer wall of the rotating shaft 3110, thereby ensuring a close fit between the outer wall of the rotating shaft 3110 and the inner wall of the rotating hole, thereby improving the stability of the rotating shaft 3110 during rotation.

[0031] The auxiliary retracting and extending mechanism 32 includes a connecting plate 321 fixedly connected to the outer wall of one side of the support plate 3111, and a sliding hole is opened on the outer wall of the connecting plate 321 away from the support plate 3111, and a spring 322 is fixedly connected to the inner wall of the sliding hole, and the spring 322 is fixedly connected to the sliding rod 323 at one end away from the inner wall of the sliding hole. The outer wall of the sliding rod 323 is slidably arranged on the inner wall of the sliding hole, and the sliding rod 323 is fixedly connected to the outer wall of one side of the pod body 2 at one end away from the spring 322. A force-bearing rod 324 is fixedly connected to the outer wall of one side of the pod body 2, and an extrusion block 325 is fixedly connected to the bottom end of the mounting plate 1.

[0032] Furthermore, there are two slide bars 323 , which are distributed on the outer wall of one end of the pod body 2 in a left-right symmetrical structure, thereby evenly supporting the left and right sides of the pod body 2 to improve the stability of the pod body 2 .

[0033] Furthermore, the outer wall of the sliding rod 323 fits snugly against the inner wall of the sliding hole, and a slope is provided on the outer wall of one side of the extrusion block 325, thereby ensuring the stability of the sliding rod 323 during movement on the inner wall of the sliding hole. At the same time, the inclined surface on the outer wall of the extrusion block 325 can be used to squeeze the force-bearing rod 324.

[0034] The implementation principle of the rotating and retracting mechanism of the drone pod of this embodiment is as follows: when the pod body 2 needs to be retracted, the motor 312 is first started, and its output end will drive the screw rod 313 to rotate. The rotation of the screw rod 313 can drive the threaded sleeve 314 to move to the left, and the movement of the threaded sleeve 314 can drive the protective cover 315 to move to the left. At the same time, the protective cover 315 will drive the limiting slider 318 on the other side to slide on the inner wall of the limiting slide groove 317, so as to improve the moving support stability of the protective cover 315. During the movement of the protective cover 315, the push plate 316 will be driven to move. During the movement of the push plate 316, it can contact and move the vertical pod body 2. The pod body 2 is squeezed and rotated upward in a clockwise direction by the rotation of the rotating shaft 3110. At the same time, the rotation of the rotating shaft 3110 will drive the torsion spring 319 to rotate. As the protective cover 315 continues to move, the pod body 2 can be squeezed and pushed continuously until the pod body 2 is pushed and stored in the storage groove at the center of the mounting plate 1. When releasing, the motor 312 can be reversed to drive the protective cover 315 to move to the right, so that the pod body 2 loses its limiting effect. Then, the pod body 2 can be pushed downward by the rebound rotation of the torsion spring 319 to complete the release. In this way, it can be ensured that the drone will not collide with the pod body 2 and cause damage during landing.

[0035] When the pod body 2 is rotated upward for storage, the connecting plate 321 will be driven to rotate upward, thereby driving the force-bearing rod 324 to move. At this time, the force-bearing rod 324 will contact and be squeezed by the squeezing block 325 during the upward rotation process. The force-bearing rod 324 will drive the pod body 2 to move to the right through the sliding of the slide bar 323. The sliding of the slide bar 323 will squeeze the spring 322, which can shorten the overall length of the pod body 2 and reduce the overall volume, thereby reducing the storage space of the pod body 2 and making it easier to store.
