Definitions
- the invention relates to a drone frame.
- UAVs on the market will be equipped with a buffer structure.
- the existing UAV buffer is generally equipped with a rubber pad on the drone frame. The rubber pad is wrapped on the landing gear of the unmanned home.
- the buffer structure has a poor buffering effect. The use is not ideal.
- the present invention provides an unmanned aerial vehicle frame in order to solve the above-mentioned problems in the prior art.
- a drone frame including a frame body, a buffer rod, a guide rod, a first spring, a second spring, a first sliding block, a second sliding block, a mounting block and a connection Rods, a number of guide rods are fixed on the upper and lower end faces of the frame body, and the guide rods on the upper end face of the frame body and the guide rods on the lower end face of the frame body are arranged in the form of spokes;
- the first spring, the second spring, the first sliding block and the second sliding block are slidably connected, the mounting block is fixedly connected to the guide rod, and the first sliding block and the second sliding block are placed on both sides of the mounting block.
- Both ends of the first slider and the second slider are provided with a first spring and a second spring, and the first spring and the second spring correspond to the first slider and the second slider; the buffer rod
- the top ends of the two connecting rods are all hinged on the buffer rod, and the bottom ends of the two connecting rods are correspondingly hinged on the first sliding block and the second sliding block.
- the end of the guide rod is provided with a limiting protrusion, and the first spring abuts on the limiting protrusion.
- the buffer bar is inclined outwards on the frame body, and the inclination angle is 20-35°.
- a rubber sleeve is sleeved on the buffer rod.
- the frame body is made of aluminum.
- At least four guide rods are provided on each end surface of the frame body.
- the invention integrates the landing gear and the buffer of the drone into one body, ensuring a good buffer effect while not occupying space, with simple structure and reasonable design.
- the weight of the drone is pressed on the buffer rod Above, the buffer rod 2 compresses the spring to play a buffer role.
- the spring rebounds, which can give the UAV a force to facilitate the UAV to take off.
- Figure 1 is a front view of the present invention.
- Figure 2 is a top view of the present invention.
- Fig. 3 is a diagram of the installation structure of the buffer rod in the present invention.
- an unmanned aerial vehicle frame of the present invention includes a frame body 1, a buffer rod 2, a guide rod 3, a first spring 4, a second spring 5, a first sliding block 6, and a second sliding block.
- a number of guide rods 3 are fixed on the upper and lower end surfaces of the frame body 1, and the guide rods 3 on the upper end of the frame body 1 and the guide rods 3 on the lower end of the frame body 1 are both arranged in a spoke shape.
- the first spring 4, the second spring 5, the first slider 6 and the second slider 7 are slidably connected to each guide rod 3, and the mounting block 8 is fixedly connected to the guide rod 3, wherein the first slider 6
- the second and second sliding blocks 7 are placed on both sides of the mounting block 8.
- a first spring 4 and a second spring 5 are provided at both ends of the first sliding block 6 and both ends of the second sliding block 7. The first spring 4 and the second spring 5 abut on the first slider 6 and the second slider 7 correspondingly.
- the buffer rod 2 is obliquely and fixedly connected to the mounting block 8. All the buffer rods 2 on the upper end surface of the frame body 1 and all the buffer rods 2 on the lower end surface form an outwardly expanding landing gear structure.
- Two connecting rods 9 are hinged on each buffer rod 2, the top ends of the two connecting rods 9 are hinged to the buffer rod 2, and the bottom ends of the two connecting rods 9 are correspondingly hinged to the first slider 6 and the second slider 7 on.
- a limit protrusion 31 is provided at the end of the guide rod 3, and the first spring 4 abuts on the limit protrusion 31.
- the buffer bar 2 in the present invention is inclined outward on the frame body 1, and the inclination angle is 20-35°.
- a rubber sleeve is sleeved on the buffer rod 2.
- the rubber sleeve can better protect the buffer rod, and on the other hand, the rubber sleeve can also play a buffer role.
- the frame body 1 in the present invention is made of aluminum and has high strength.
- At least four guide rods 3 are provided on each end surface of the frame body 1.
- the invention integrates the landing gear and the buffer of the drone into one body, ensuring a good buffer effect while not occupying space.
- the structure is simple and the design is reasonable.
- the weight of the drone is pressed on the buffer rod.
- the buffer rod 2 compresses the spring to play a buffer role.
- the spring rebounds, which can give the UAV a force to facilitate the UAV to take off.
