[0026] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0027] It will be understood that, although the terms “first”, “second”, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another.

[0028] Embodiment 1

[0029] Combination Figures 1 to 5As shown, a multi-rotor drone carrying platform and a drone having such a multi-rotor drone carrying platform are disclosed in this embodiment. The multi-rotor drone carrying platform includes a bearing frame 1, a bearing substrate 2, four machine arms 3 and four tripods 4. The bearing frame 1 of this embodiment is annular as a whole. The bearing frame 1 of this embodiment includes two bearing units 11, four connecting shafts 12 and four connecting brackets 13. The two bearing units 11 are arranged coaxially up and down, and the four connecting shafts 12 connect the two bearing units 11 to form a whole. Specifically, each bearing unit 11 includes four connecting rods 111 and connecting elbows 112, and the four connecting rods 111 and the four connecting elbows 112 are staggered and connected in sequence to form a closed rectangular ring, that is, every two connected connecting rods 111 are fixedly connected by a connecting elbow 112. The connecting elbows 112 of the two bearing units 11 arranged up and down are arranged one by one, and every two corresponding connecting elbows 112 are connected by a connecting shaft 12. It is easy to understand that by changing the length of the connecting shaft 12, the height of the load-bearing frame 1 can be changed, which is equivalent to changing the capacity of the load-bearing frame 1 to load the equipment. Of course, changing the length of the four connecting rods 111 can also change the capacity of the load-bearing frame 1. It is easy to understand that the currently commonly used drones are all four-axis flight, so in this embodiment, four arms 3 are provided to install four drive motors and corresponding rotors. In other words, when the drone has six axes or more drive motors, the number of connecting rods 111 and connecting elbows 112 in a load-bearing unit 11 and the number of arms 3 can be changed accordingly.

[0030] A connecting bracket 13 is connected to every two adjacent connecting rods 111 of the two bearing units 11 of this embodiment; each connecting bracket 13 is L-shaped, and two connecting holes are provided on one arm of the connecting bracket 13. The connecting bracket 13 is slidably mounted on the two corresponding connecting rods 111 through the two connecting holes, and the other arm of the connecting bracket 13 faces the bearing substrate 2 and is detachably connected to the lower surface of the substrate. The connecting bracket 13 can make the structure of the bearing frame 1 more stable, and at the same time, it can facilitate the fixing and installation of the bearing substrate 2. Of course, the installation form of the bearing substrate 2 is not limited to being fixed by the connecting bracket 13. The bearing substrate 2 is installed inside the bearing frame 1, and a plurality of mounting holes are provided on the bearing substrate 2. The mounting holes are not only used for installing test equipment, but also for bolting the bearing substrate 2 to the bearing frame 1.

[0031] The four arms 3 of this embodiment are respectively hinged to the four connecting shafts 12 in a one-to-one correspondence, that is, the four arms 3 are arranged at equal angles around the center of the supporting frame 1. And when the arms 3 are unfolded, two opposite arms 3 are located on the same straight line and are perpendicular to the connecting line of the other two arms 3. A rotating drum is installed at one end of the arm 3, and the rotating drum is sleeved on the corresponding connecting shaft 12, and the other end of the arm 3 is fixedly connected to a motor seat 5, and the motor seat 5 is used to install a drive motor. The motor seat 5 of this embodiment has two mounting surfaces, which is convenient for installing drive motors of different specifications.

[0032] It is worth noting that the arm 3 can rotate on the connecting shaft 12, so the arm 3 needs to be fixed during the test. Therefore, the load-bearing frame 1 of this embodiment also includes a U-shaped block 6, a rubber stopper 7 and a stopper rod 8, and the number of the U-shaped block 6, the rubber stopper 7 and the stopper rod 8 corresponds to the number of the connecting elbows 112 in a load-bearing unit 11. A U-shaped block 6 is fixedly installed between every two corresponding connecting elbows 112, that is, the U-shaped block 6 is transversely fixed between the two corresponding connecting elbows 112 and is located outside the connecting shaft 12, and the opening of the U-shaped block 6 faces the arm 3, and the arm 3 can be clamped in the U-shaped block 6 during the rotation process. It is worth noting that a slide groove is provided on the two side walls of each U-shaped block 6, and a limit groove is formed at the bottom of each slide groove, the width of the limit groove is greater than the width of the slide groove, and a limit rod 8 is connected to each side of the rubber limit block 7, and the rubber limit block 7 is operably slidably set between the two side walls of the U-shaped block 6, and the two limit rods 8 are respectively slidably set in the slide groove and the limit groove in a one-to-one correspondence. Then, when the machine arm 3 rotates on the connecting shaft 12 to be clamped in the U-shaped block 6, the rubber limit block 7 can be abutted against the machine arm 3 and slid between the two side walls of the U-shaped block 6, and at the same time, the two limit rods 8 slide in the slide groove in a one-to-one correspondence. It is easy to understand that the rubber limit block 7 is compressed when it abuts the arm 3. When it slides to the limit groove, the limit rod 8 has a certain movable space. Therefore, the limit rod 8 can retreat to the limit groove under the action of the elastic force of the rubber limit block 7, and the limit groove can limit the further sliding of the limit rod 8, thereby tightly fixing the rubber limit block 7 between the two side plates of the U-shaped block 6. At the same time, the rubber limit block 7 prevents the arm 3 from rotating, so that the arm 3 can be stably unfolded when in use.

[0033] It is easy to understand that after the limit rod 8 is pushed toward the direction of the machine arm 3 and the limit rod 8 overcomes the elastic force of the rubber limit block 7 and reaches the slide slot, the rubber limit block 7 can be taken out along the slide slot. At this time, the machine arm 3 can be rotated to be parallel to the connecting rod 111 of the carrying unit 11. At this time, a C-shaped clamp is formed on the end face of one arm of each corresponding connecting bracket 13 facing away from the carrying substrate 2, and the four machine arms 3 can be operably clamped in the four C-shaped clamps respectively, so that the machine arms 3 are folded and fixed when not in use.

[0034] Furthermore, the four legs 4 are connected to the four connecting elbows 112 in a one-to-one correspondence, and the legs 4 include a first leg arm 41 and a second leg arm 42. One end of the first leg arm 41 is rotatably connected to the connecting elbow 112, and the other end is rotatably connected to the second leg arm 42. Specifically, in this embodiment, the first leg arm 41 includes two clamping plates 411, two rotating shafts 412, a pull rod 413 and a spring 414. The two rotating shafts 412 are respectively connected to the two ends of the two clamping plates 411, one rotating shaft 412 is rotatably connected to the connecting elbow 112, and the other rotating shaft 412 is rotatably connected to the second leg arm 42; the pull rod 413 is connected to the middle of the two clamping plates 411, and one end of the spring 414 is fixedly connected to the pull rod 413, and the other end is fixedly connected to one end of the second leg arm 42 facing the first leg arm 41. It is worth noting that the two clamping plates 411 have a limiting hole formed at one end facing the connecting elbow 112, and a screw hole is formed on the connecting elbow 112. The clamping plates 411 and the connecting elbow 112 are fixedly connected by screws passing through the limiting hole and the screw hole. The first leg arm 41 can also be rotated and folded by loosening the screw, so as to minimize the space occupied by the platform when not in use, and facilitate storage.

[0035] The drone of this embodiment includes the multi-rotor drone carrying platform of this embodiment, and the electronic equipment of the drone is integrated on the multi-rotor drone carrying platform, which is convenient and quick to install and convenient to debug the drone.

[0036] The above are only preferred specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
