Description

Technical Field

DETAILED DESCRIPTION

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0030] like Figures 1 to 6 A foldable drone with a shock-absorbing structure is shown, characterized in that it includes: a first frame 1, a second frame 2 is movably hinged on one side of which, buckles 11 are symmetrically fixed on the first frame 1 and the second frame 2, respectively, and the support rod 52 is engaged with the buckle 11 when flipping upward, the second frame 2 is movably hinged on the first frame 1, and swing rods 3 are symmetrically sleeved and inserted on the first frame 1 and the first frame 1, and blades 6 are provided at the ends of the swing rods 3, and a camera 4 is provided on the first frame 1; a plurality of support parts 5 are respectively arranged on the first frame 1 and the second frame 2, and are used to support the first frame 1 and the second frame 2; a shock-absorbing mechanism 100, which is respectively connected to the first frame 1 and the second frame 2, and is used to shock the first frame 1 and the second frame 2 when the support part 5 contacts the ground; a linkage mechanism 200, which is arranged in the second frame 2, and is used to flip the first frame 1 to the second frame 2 and fold each swing rod 3 to the first frame 1 and the second frame 2; a driving mechanism 300, which is arranged on the right side of the second frame 2, and is used to drive the linkage mechanism 200 to operate.

[0031] A foldable drone with a shock-absorbing structure of the above structure, when in use, the blades 6 on the swing rod 3 rotate to push the airflow, so that the first frame 1 and the second frame 2 are suspended, and the camera 4 on the first frame 1 is used to shoot or record. When the drone lands, the support parts 5 on the first frame 1 and the second frame 2 first contact the ground. At this time, the first frame 1 and the second frame 2 are shock-absorbing by the shock-absorbing mechanism 100. After the drone is used, the driving mechanism 300 is started to start the linkage mechanism 200. At this time, the linkage mechanism 200 flips the first frame 1 to the second frame 2 and folds each swing rod 3 to the first frame 1 and the second frame 2. Compared with the existing technology, the shock-absorbing effect of the drone is improved, and the simple and complex structure reduces the weight of the drone. At the same time, the drone body and blades can be automatically folded to reduce the occupied area of ​​the drone, which is convenient to carry.

[0032] like Figure 3 As shown, in some embodiments of the present invention, the support portion 5 includes a fixed plate 51 fixed on opposite sides of the first frame 1 and the second frame 2, and support rods 52 are symmetrically and movably hinged on the fixed plate 51, and support feet 53 are movably inserted in the support rods 52, and the lower part of the support feet 53 is placed horizontally on the ground, wherein the support rods 52 are movably hinged on the fixed plate 51, and at the same time, the support feet 53 are movably inserted in the fixed plate 51, so that the shock absorbing mechanism 100 has enough space and distance to operate during shock absorption, and when the support rods 52 are flipped upwards, they are clamped and fixed to the first frame 1 and the second frame 2 through the buckle 11.

[0033] like Figure 3 and 4 As shown, in some embodiments of the present invention, in order to achieve the effect of cushioning the first frame 1 and the second frame 2 when the support portion 5 contacts the ground, the cushioning mechanism 100 includes a plurality of through slots 101 provided on the support rods 52, a first connecting rod 102 is movably hinged on the support rod 52 and passes through the through slots 101, a cross plate 103 is laterally fixed above the first frame 1, a second connecting rod 104 is symmetrically movably hinged on the cross plate 103, the first connecting rod 102 and the second connecting rod 104 are movably hinged to each other, connecting plates 105 are movably hinged at the ends of the first connecting rod 102 and the second connecting rod 104, and a spring 106 is connected between every two connecting plates 105.

[0034] When a foldable drone with a shock-absorbing structure using the above structure is in operation, the support foot 53 is in contact with the ground. At this time, the first connecting rod 102 on the support foot 53 and the second connecting rod 104 on the cross plate 103 swing with each other. At the same time, a spring 106 connected between the two connecting plates 105 generates an elastic force downward on the support foot 53, and the support foot 53 moves along the support rod 52 to prevent the first frame 1 and the second frame 2 from vibrating directly when the drone lands.

[0035] like Figure 2 and 4 As shown, in some embodiments of the present invention, in order to achieve the effect of flipping the first frame 1 toward the second frame 2 and folding each swing rod 3 toward the first frame 1 and the second frame 2, the linkage mechanism 200 includes a T-shaped plate 201 fixed above the second frame 2, and a moving rod 202 is symmetrically sleeved on the T-shaped plate 201. One end of the moving rod 202 is movably sleeved on the front and rear sides above the second frame 2, and a guide groove 203 is fixed below the moving rod 202. The guide groove 203 is connected to the driving mechanism 300, and a through hole 204 is provided on one side of one of the fixed plates 51 close to the second frame 2, and a guide rail 206 is fixed below the T-shaped plate 201. The guide rail 206 has a right side extending obliquely downward, and the left side of the guide rail 206 is arc-shaped. The center of the arc of the guide rail 206 is the hinge between the hook 205 and the through slot 101. The through hole 204 is provided with a hook 205, and the hook 205 is arc-shaped. The middle part of the hook 205 extends upward and protrudes. The right side of the hook 205 is movably arranged in the guide rail 206, and the left end of the hook 205 is movably hinged in the through slot 101. The hook 205 is connected to the driving mechanism 300. The guide rail 206 has a right side extending obliquely downward, and the left side of the guide rail 206 is arc-shaped, and the center of the arc of the guide rail 206 is the hook 205.

[0036] When a foldable drone with a shock-absorbing structure using the above structure is in operation, the driving mechanism drives the hook 205 to move, and at the same time, the guide groove 203 moves. The hook 205 first moves along the guide rail 206 below the T-shaped plate 201, and the right side of the guide rail 206 extends obliquely downward, so that the end of the hook 205 drives the first frame 1 to flip upward through the through hole 204, and the center of the arc on the left side of the guide rail 206 is the hinge between the hook 205 and the through groove 101, so that the end of the hook 205 drives the first frame 1 to cover the second frame 2 through the through hole 204, and at the same time, the guide groove 203 drives the moving rod 202 to move. When the moving rod 202 moves, it drives two of the swing rods 3 to flip toward the second frame 2. When covering, the other two swing rods 3 are flipped toward the first frame 1 through the driving mechanism.

[0037] like Figure 2 and4 As shown, in some embodiments of the present invention, in order to achieve the effect of driving the linkage mechanism 200, the driving mechanism 300 includes a motor seat 301 movably hinged under the T-shaped plate 201, a motor 302 is fixed on the motor seat 301, a screw 303 is fixed at the output end of the motor 302, a threaded sleeve 304 is sleeved on the screw 303, a connecting portion 305 is provided at the end of the threaded sleeve 304, the hook 205 is movably hinged on the connecting portion 305, levers 306 are movably hinged between two of the swing rods 3 and each moving rod 202, and a first straight Gear 307, a rotating shaft 308 is symmetrically sleeved on the left side of the first frame 1, and a second spur gear 309 and a first bevel gear 310 are respectively fixed at the upper and lower ends of the rotating shaft 308, and the second spur gear 309 is meshed with the first spur gear 307, and an insertion shaft 311 is movably inserted on the first frame 1 near the rotating shaft 308, and a second bevel gear 312 and a third spur gear 313 are respectively fixed at the left and right ends of the insertion shaft 311, and the second bevel gear 312 is meshed with the first bevel gear 310, and an arc rack 314 is symmetrically fixed at the lower right side of the second frame 2, and the arc rack 314 is meshed with the third spur gear 313.

[0038] When a foldable drone with a shock-absorbing structure using the above structure is in operation, the power supply is connected to the motor 302 on the motor seat 301, so that the motor 302 and the screw 303 rotate. When the screw 303 rotates, the threaded sleeve 304 of the screw 303 moves toward the hook 205, thereby driving the hook 205 to move along the guide rail 206 through the connecting part 305. When the hook 205 moves along the guide rail 206, because the motor seat 301 is movably hinged under the T-shaped plate 201, the motor seat 301 will swing to different angles with the movement of the hook 205. When the left end of the hook moves to the end of the guide rail 206, the first frame 1 completely covers and is in the first On the second frame 2, the guide groove 203 is driven to move by the threaded sleeve 304, so that the movement 202 moves two of the swing rods 3 toward the second frame 2 through the lever 306. When the first frame 1 is covered, the arc rack 314 on the second frame 2 contacts the third spur gear 313, so that the third spur gear 313 rotates and the second bevel gear 312 rotates through the plug shaft 311. The second bevel gear 312 drives the first bevel gear 310 to rotate. The first bevel gear 310 drives the second spur gear 309 to rotate through the rotating shaft 308. The second spur gear 309 rotates the first spur gear 307, thereby achieving the effect of the other two swing rods 3 swinging toward the first frame.

[0039] like Figure 6As shown, in some embodiments of the present invention, a foldable drone with a shock-absorbing structure is characterized in that the connecting part 305 includes a sleeve rod 3051 movably inserted into the left end of the threaded sleeve 304, and a pressure spring 3052 is wound on the sleeve rod 3051. The end of the sleeve rod 3051 is movably hinged to the hook 205, and the hook 205 is hinged through the sleeve rod 3051. When the hook 205 moves to the end of the guide rail 206, the pressure spring 3052 presses the hook 205 to prevent the hook 205 from loosening. When the hook 205 moves to the head end of the guide rail 206, the sleeve rod 305 is fully extended in the threaded sleeve 304 and the inner end of the threaded sleeve 304 blocks the end of the sleeve rod 305, so that the sleeve rod 305 tightens the hook 205 to prevent it from loosening.
