[0032] Example 1

[0033] Please refer to Figures 1-6 The first embodiment of the present invention provides a frame protection structure 100, including a body 110, a connecting frame 120 and a protective frame 130; the connecting frame 120 includes a connecting plate 121 and a mounting seat 122, the connecting plate 121 is connected to the body 110, the mounting seat 122 is connected to the connecting plate 121, a support portion 1221 is provided on the periphery of the mounting seat 122, a limiting body 12211 is protruded at the end of the support portion 1221, a positioning groove 1222 and a buckling groove 1223 are formed at intervals on the periphery of the mounting seat 122, and the support portion 1221 is located between the positioning groove 1222 and the buckling groove 1223; the protective frame 130 includes an annular body 1 31. A first baffle portion 132, a second baffle portion 133 and a hollow cover 134. The first baffle portion 132 and the second baffle portion 133 are spaced apart and connected to one side of the annular body 131. The hollow cover 134 is connected to the other side of the annular body 131. The first baffle portion 132 and the second baffle portion 133 are located on the same side of the annular body 131. The first baffle portion 132 is inserted into the positioning groove 1222, the supporting portion 1221 elastically abuts against the annular body 131, and the limiting body 12211 abuts against the side of the annular body 131. The second baffle portion 133 is inserted into the snap-fit ​​groove 1223 to enable the protective frame 130 to be detachably connected to the connecting frame 120. In a specific application, since the first baffle portion 132 is inserted into the positioning groove 1222, the support portion 1221 elastically abuts against the annular body 131, and the limiting body 12211 abuts against the side of the annular body 131, the second baffle portion 133 is inserted into the buckling groove 1223, so that the protective frame 130 and the connecting frame 120 are detachably connected, wherein the protective frame 130 includes the annular body 131, the first baffle portion 132, the second baffle portion 133 and the hollow cover 134, and the hollow cover 134 is connected to one side of the annular body 131, thereby 00 is provided above the hollow cover 134, which overcomes the difficulty faced by the UAV 10 in the prior art in setting up a protective structure to ensure aerodynamic balance above the propeller 300. It is worth noting that the hollow cover 134 is provided on the annular body 131 without affecting the flow of air intake of the propeller 300, which is beneficial to reducing the potential safety hazards during the flight of the UAV 10, and the hollow cover 134 and the annular body 131 are integrally formed into a protective frame 130, so that when the UAV 10 is transported and carried, the occupied storage space can be reduced by disassembling and assembling the protective frame 130.

[0034] In one possible embodiment, the hollow cover 134 is formed with a first inclined curved bar 1341, a second inclined curved bar 1342, a third inclined curved bar 1343, a first inclined curved frame 1344 and a second inclined curved frame 1345, wherein the first inclined curved frame 1344 and the second inclined curved frame 1345 are bent and connected, the first inclined curved bar 1341 is connected between the annular body 131 and the first inclined curved frame 1344, the second inclined curved bar 1342 is connected between the annular body 131 and the second inclined curved frame 1345, and the third inclined curved bar 1343 is connected between the first inclined curved bar 1341 and the second inclined curved bar 1342, so that an inclined hollow surface 1346 is formed between the first inclined curved frame 1344 and the second inclined curved frame 1345 and the annular body 131 respectively. In a specific application, the hollow cover 134 is formed with a first oblique curved strip 1341, a second oblique curved strip 1342, a third oblique curved strip 1343, a first oblique curved frame 1344 and a second oblique curved frame 1345, and there is no limit on the number. Among them, the first oblique curved frame 1344 and the second oblique curved frame 1345 are bent and connected above the propeller 300. The first oblique curved frame 1344 and the second oblique curved frame 1345 are respectively curved tripods, and the material has the characteristics of light weight and high strength, thereby reducing the air resistance above the propeller 300. In addition, the first oblique curved strip 1341 forms a certain arc and is connected between the annular body 131 and the first oblique curved frame 1344. The second oblique curved strip 1342 forms a certain arc and is connected between the annular body 131 and the second oblique curved frame 1345. The third oblique curved strip 1343 is adapted to be connected between the first oblique curved strip 1341 and the second oblique curved strip 1342 to increase the overall strength of the hollow cover 134, so that an oblique hollow surface 1346 is formed between the first oblique curved frame 1344 and the second oblique curved frame 1345 and the annular body 131 respectively. It is worth noting that the oblique hollow surface 1346 is hollow and is located obliquely above the propeller 300, which can greatly reduce the air resistance of the propeller 300 when taking in air at the upper side, so that the hollow cover 134 reduces the aerodynamic impact on the drone 10.

[0035] In one possible embodiment, the radius of curvature of the obliquely curved hollow surface 1346 is positively correlated with the blade angle of the propeller 300. In specific applications, to optimize the effect of the hollow cover 134 on the aerodynamics of the drone 10, research has found that the radius of curvature of the obliquely curved hollow surface 1346 can be designed based on the blade angle of the propeller 300. Consequently, the curvature of the first obliquely curved strip 1341, the second obliquely curved strip 1342, the third obliquely curved strip 1343, the first obliquely curved frame 1344, and the second obliquely curved frame 1345 can be designed based on the curvature radius of the obliquely curved hollow surface 1346.

[0036] In one possible embodiment, the thickness of the first oblique curved strip 1341 gradually decreases from the annular body 131 to the first oblique curved frame 1344; and the thickness of the second oblique curved strip 1342 gradually decreases from the annular body 131 to the second oblique curved frame 1345. In a specific application, to reduce the load of the drone 10 and improve the structural strength of the hollow cover 134, the thickness of the first oblique curved strip 1341 gradually decreases from the annular body 131 to the first oblique curved frame 1344. Similarly, the thickness of the second oblique curved strip 1342 gradually decreases from the annular body 131 to the second oblique curved frame 1345, thereby improving the structural strength of the hollow cover 134 and lowering its center of gravity.

[0037] In one possible embodiment, the second baffle portion 133 includes a second baffle body 1331, a adapter body 1332 and an inclined wedge block 1333. The adapter body 1332 is connected between the second baffle body 1331 and the inclined wedge block 1333. When the second baffle portion 133 is inserted into the snap-fit ​​groove 1223, the adapter body 1332 is inserted into the snap-fit ​​groove 1223, and the inclined wedge block 1333 is snapped into the snap-fit ​​groove 1223. In specific applications, since the adapter body 1332 is connected between the second baffle body 1331 and the inclined wedge block 1333, when the second baffle part 133 is inserted into the snap-fit ​​groove 1223, the adapter body 1332 is inserted into the snap-fit ​​groove 1223, and the inclined wedge block 1333 is snapped into the snap-fit ​​groove 1223. In the absence of intervention by external human force, the second baffle part 133 is firmly snapped into the snap-fit ​​groove 1223, thereby firmly connecting the protective frame 130 to the connecting frame 120.

[0038] In one possible embodiment, a gap is formed between the adapter body 1332 and the engaging groove 1223, and the adapter body 1332 elastically deforms relative to the second baffle body 1331, thereby disengaging the inclined wedge block 1333 from the engaging groove 1223. In a specific application, due to the gap between the adapter body 1332 and the engaging groove 1223, when the protective frame 130 is manually disassembled, the adapter body 1332 elastically deforms relative to the second baffle body 1331 in the gap, thereby disengaging the inclined wedge block 1333 from the engaging groove 1223, thereby improving the portability of the disassembly operation.

[0039] In one possible embodiment, reinforcing ribs 1334 are formed on both sides of the second baffle body 1331, and the ribs 1334 gradually decrease in size from the annular body 131 toward the oblique wedge block 1333. In a specific application, the formation of the reinforcing ribs 1334 on both sides of the second baffle body 1331 improves the strength of the elastic deformation of the second baffle body 1331. In addition, it can be understood that the deformation of the second baffle body 1331 is equivalent to the elastic deformation process of the suspension, that is, the deformation is small near the snap-fit ​​groove 1223 and large away from the snap-fit ​​groove 1223. Therefore, the gradual reduction of the reinforcing ribs 1334 from the annular body 131 toward the oblique wedge block 1333 can ensure uniform force distribution during the deformation of the baffle.

[0040] In one possible embodiment, the first baffle portion 132 includes a first baffle body 1321, a connecting post 1322, and a lug 1323. The lug 1323 is connected to the end of the first baffle body 1321, the connecting post 1322 is located in the middle of the lug 1323, the mounting base 122 is located in the center of the positioning slot 1222 and has a connecting hole 1224 formed therein. The lug 1323 is snap-fitted into the positioning slot 1222 so that the connecting post 1322 is aligned and connected with the connecting hole 1224. In a specific application, since the lug 1323 is connected to the end of the first baffle body 1321, the connecting post 1322 is located in the middle of the lug 1323, and the mounting base 122 is located in the center of the positioning slot 1222 and has a connecting hole 1224 formed therein, the lug 1323 can be guided and snap-fitted into the positioning slot 1222, so that the connecting post 1322 is aligned with the connecting hole 1224 and then securely connected.

[0041] Example 2

[0042] The subject matter protected in this embodiment is different from that in the first embodiment, and the specific differences are as follows:

[0043] Please refer to Figure 7-Figure 9 Embodiment 2 of the present invention provides a drone 10, including the above-mentioned frame protection structure 100, a brushless motor 200, a propeller 300, a controller 400 and a power supply 500. The brushless motor 200 is installed on the mounting seat 122 to drive the propeller 300 to rotate. The propeller 300 is located between the hollow cover 134 and the mounting seat 122. The controller 400 is electrically connected to the brushless motor 200, and the power supply 500 distributes electrical energy to the brushless motor 200 according to the controller 400. In a specific application, the brushless motor 200 is installed on four mounting seats 122, and four propellers 300 are distributed and fixed on the rotating shaft of the brushless motor 200, so that the brushless motor 200 drives the propeller 300 to rotate. Since the propeller 300 is located between the hollow cover 134 and the mounting seat 122, the hollow cover 134 is located directly above the propeller 300, and effectively protects the top of the propeller 300 without affecting the aerodynamics of the propeller 300. The controller 400 is electrically connected to the brushless motor 200 to control the speed of the propeller 300, and the power supply 500 distributes current to the brushless motor 200 according to the signal of the controller 400, thereby adjusting the speed of the propeller 300 to enable the drone 10 to fly normally.

[0044] In one possible embodiment, the drone 10 further includes a camera module 600, which includes a camera 610, a drive motor 620, a support frame 630, and a shock absorber 640. The camera 610 is connected to the fuselage 110 of the drive motor 620, the rotation shaft of the drive motor 620 is rotatably connected to the support frame 630, and the shock absorber 640 is connected between the support frame 630 and the mounting base 122. In a specific application, since the camera 610 is connected to the fuselage 110 of the drive motor 620 and the rotation shaft of the drive motor 620 is rotatably connected to the support frame 630, when the drive motor 620 rotates, it drives the rotation of the camera 610. The shock absorber 640 is connected between the support frame 630 and the mounting base 122. In this way, the impact of high-frequency vibration of the air on the mounting base 122 on the shaking of the camera 610 can be reduced.

[0045] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
