[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a UAV carrying device, including a carrying platform 1, which is a prior art. The carrying platform 1 can be used to carry a UAV and can bring the UAV to a designated area. A UAV is provided on the upper part of the carrying platform 1. The UAV includes a landing bracket 3. The upper end of the landing bracket 3 is fixedly connected to a UAV body 2. The UAV is a prior art. The UAV body 2 includes a spiral blade, a drive motor, a control device, etc. The lower end of the landing bracket 3 contacts the upper end of the carrying platform 1, so that the landing bracket 3 is raised when the UAV lands. To provide a supporting effect, a slide groove 11 is provided on the inner wall of the carrying platform 1, and a sliding block 5 is slidably connected to the inner wall of the slide groove 11. The slide groove 11 is engaged with the rear end protrusion of the sliding block 5 and can slide on the inner wall of the slide groove 11 to provide a guiding effect. The outer wall of the sliding block 5 is fixedly connected to the sliding arm 4. The sliding block 5 moves inward to tighten the sliding arms 4 on both sides. The tightening of the sliding arms 4 will adjust the drone to a horizontal state after landing on the carrying platform 1. The outer wall of the sliding arm 4 is slidably connected to the connecting block 7. The retracting rod 8 and the extending rod 12 are relatively fixed to the sliding arm 4 through the connecting block 7 to provide a fixing effect.

[0034] Reference Figure 2 、 Figure 5 , there are two groups of connecting blocks 7. The lower end of one group of connecting blocks 7 is fixedly connected to the retracting rod 8, and the lower end of the other group of connecting blocks 7 is fixedly connected to the extending rod 12. The inner wall of the retracting rod 8 is slidably connected to the outer wall of the extending rod 12. When the sliding arms 4 on both sides move inward, the extending rod 12 will be driven to retract and retract on the inner wall of the retracting rod 8. The connecting block 7 drives the extending rod 12 and the retracting rod 8 to move inward, so that the drone moves to the designated position after landing. The outer walls of the retracting rod 8 and the extending rod 12 are both provided with a self-locking mechanism. The self-locking mechanism will self-lock when the connecting block 7 moves to make the self-locking block 15 contact the landing bracket 3, thereby providing a fixing effect for the drone.

[0035] Reference Figure 2 、 Figure 4 The outer wall of the connecting block 7 is fixedly connected to the motor 6. The motor 6 and the motor 6 are the existing technology and can drive the output end connection part to rotate. The inner wall of the connecting block 7 is rotatably connected to the pulley 9. The outer wall of the pulley 9 is made of rubber material with large friction, so that the pulley 9 will not slip and idle when sliding on the sliding arm 4. The output end of the motor 6 is fixedly connected to the outer wall of the pulley 9, so that the motor 6 drives the pulley 9 to rotate. The outer wall of the pulley 9 is slidably connected to the outer wall of the sliding arm 4, so that the rotation of the pulley 9 will drive the connecting block 7 to move on the sliding arm 4.

[0036] refer to Figure 3 The outer wall of the sliding block 5 is fixedly connected to a rack 10. The rack 10 has two groups, an upper group and an lower group, and the two groups of racks 10 are in opposite directions. The outer wall of the rack 10 is engaged with a gear 19. The rotation of the gear 19 will cause the upper and lower racks 10 to move in opposite directions, causing the sliding block 5 to shrink. The outer wall of the gear 19 is rotatably connected to the outer wall of the carrying platform 1. The output end of another group of motors 6 is fixedly connected to the gear 19, and the motor 6 will drive the gear to rotate.

[0037] refer to Figure 2 、 Figure 6The self-locking mechanism includes a protrusion 13, which is provided with two groups. The outer wall of one group of protrusions 13 is fixedly connected to the outer wall of the retracted rod 8, and the outer wall of the other group of protrusions 13 is fixedly connected to the outer wall of the extension rod 12, so that the extension rod 12 and the retracted rod 8 provide a fixing effect for the protrusion 13, and the inner wall of the protrusion 13 is rotatably connected with a locking plate 14. When the lock plate 14 is rotated to a vertical position, it will be stuck with the protrusion 13 to provide a fixing effect for the landing bracket 3, and the lock plate 14 is elastically connected to the protrusion 13 by a spring 18. One end of the spring 18 is fixedly connected to the outer wall of the lock plate 14, and the other end of the spring 18 is fixedly connected to the inner wall of the protrusion 13 when no external force is applied. The spring 18 will cause the lock plate 14 to rotate to a horizontal position. When the lock plate 14 is pulled by the pull rope 16, the lock plate 14 will be vertical, and the inner wall of the protrusion 13 is slidably connected with a self-locking block 15, which is on the inner wall of the protrusion 13 The sliding movement laterally causes the protrusion 13 to provide a guiding effect on the self-locking block 15. The inner wall of the protrusion 13 is fixedly connected to a steering shaft 17. The steering shaft 17 is provided with multiple groups. The steering shaft 17 can change the force direction of the pull rope 16, so that the pulling effect on the lock plate 14 is more stable when the pull rope 16 is pulled. The steering shaft 17 prevents the pull rope 16 from directly contacting and wearing the inner wall of the protrusion 13. The outer wall of the pull rope 16 is slidably connected to the outer wall of the steering shaft 17. The lock plate 14 is connected to the self-locking block 15 through the pull rope 16. One end of the pull rope 16 is fixedly connected to the outer wall of the lock plate 14, and the other end of the pull rope 16 is fixedly connected to the right outer wall of the self-locking block 15. After the self-locking block 15 contacts the landing bracket 3, it will cause the self-locking block 15 to slide toward the inside of the protrusion 13, and the outer wall of the landing bracket 3 contacts the left outer wall of the self-locking block 15. The inward movement of the self-locking block 15 will pull the pull rope 16, and the pull rope 16 will pull the lock plate 14 to rotate.

[0038] Working principle: After the drone lands, if the drone is fixed on the carrying platform 1, after the drone lands on the carrying platform 1, the motor 6 drives the gear 19 to rotate, causing the upper and lower racks 10 to contract and drive the sliding block 5 to move, while driving the sliding arm 4 to contract inward, and at the same time causing the extension rod 12 to contract toward the inner wall of the retracted rod 8. The sliding arm 4 will correct the drone to make it parallel, and then the motor 6 will drive the pulley 9 to rotate, causing the connecting block 7 to move inward, which will drive the extension rod 12 and the retracted rod 8 to move. When it contacts the landing bracket 3, it will drive the drone to the center and fix the drone.

[0039] After the drone reaches the designated position, it needs to be fixed. When the landing bracket 3 at the bottom of the drone contacts the self-locking block 15, it will push the self-locking block 15 to slide inward of the protrusion 13. The self-locking block 15 will pull the pull rope 16, and the guidance of the steering shaft 17 can more stably drive the locking plate 14 to rotate. When the locking plate 14 rotates to a vertical position, it will be stuck with the protrusion 13 to fix the landing bracket 3.

[0040] When the drone is to be used, the motor 6 is rotated in the reverse direction, at which time the self-locking block 15 will release its contact with the landing bracket 3 , and the locking plate 14 will return to a horizontal position driven by the spring 18 to release the fixing effect.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
