Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

The utility model discloses an unmanned aerial vehicle is shock attenuation buffer gear for descending of some embodiments is described below with reference to fig. 1 to 3.

As shown in fig. 1, the utility model discloses an unmanned aerial vehicle descends and uses shock attenuation buffer gear, including setting up the shank in organism 1 bottom surface, and the shank sets up for bilateral symmetry in organism 1's bottom surface. And the support of unmanned aerial vehicle organism 1 can be regarded as in the setting of shank, and the shank has replaced the support in the frame to reduce the heavy burden to unmanned aerial vehicle. Carry out swing joint through buffering subassembly 6 between the front and back both ends of two shank, buffering subassembly 6 can cushion the impact force that unmanned aerial vehicle produced with ground when descending, reduces unmanned aerial vehicle and sends the relative subaerial impact force of shank to play the protection effect who sends the shank to unmanned aerial vehicle.

In the above, the supporting legs include the symmetrical supporting lugs 3 arranged on the front side and the rear side of the bottom surface of the machine body 1, the rotating plates 4 are rotatably connected to the outer sides of the supporting lugs 3 through the rotating shafts, the bottom ends of the two rotating plates 4 are connected through the rollers 5, the rollers 5 are rotatably arranged between the two rotating plates 4, and rubber wheels can be sleeved on the rollers 5 to increase the friction force between the rollers 5 and the bottom surface. Specifically, each rotating plate 4 is arranged obliquely outwards relative to the machine body 1, so that when the unmanned aerial vehicle lands, the rollers 5 contact the ground and start to rotate. Simultaneously, rotor plate 4 can revolute the rotation on journal stirrup 3 to gravity when making unmanned aerial vehicle descending process can be followed its whereabouts enlarges the effective area of exerting oneself of shank subaerial, with the stability of increase unmanned aerial vehicle after falling.

Of course, the baffles 2 are symmetrically arranged on the bottom surface of the machine body 1, each baffle 2 is arranged corresponding to each leg, and each baffle 2 is arranged at the inner side of each leg. The baffle plate 2 can limit the rotating plate 4, so that the rotating plate 4 can only rotate outwards on the support lug 3.

Preferably, the buffer assembly 6 includes tension springs 601 rotatably provided on the rotation plates 4, a first screw 602 is hung on the tension spring 601 of each rotation plate 4 on the left leg portion, and a second screw 604 is hung on the tension spring 601 of the rotation plate 4 on the right leg portion. The first screw 602 is connected with the second screw 604 through the screw threads of the drum 603, and the screw threads of the first screw 602 are opposite to those of the second screw 604.

Specifically, the first screw 602 and the second screw 604 can be moved outward or inward in opposition to each other by rotating the drum 603. If want to adjust the extension spring 601 pulling force on the buffering subassembly 6, rotatory rotary drum 603 realizes that first screw 602 and second screw 604 move towards the inside of rotary drum 603 for extension spring 601 on first screw 602 and the second screw 604 is stretched, causes the pulling force of buffering subassembly 6 bigger, uses to the unmanned aerial vehicle that the specification is great. Of course, the counter-rotation rotary drum 603 alright make the pulling force of buffering subassembly 6 diminish, the pulling force of buffering subassembly 6 adjust to the unmanned aerial vehicle of different specifications use can, increased shock attenuation buffer gear's practicality.

When unmanned aerial vehicle descends, unmanned aerial vehicle's organism 1 pushes down roller 5 on the rotation board 4, and roller 5 begins to rotate after contacting with ground for rotation board 4 revolutes the axle and rotates outward, and is located the extension spring 601 in the buffering subassembly 6 of two leg parts and under the effect of rotation board 4, begins to be stretched. At extension spring 601 by tensile in-process, alright disperse and cushion the impact force that unmanned aerial vehicle produced relative ground for unmanned aerial vehicle organism and shank can be protected under the effect of buffering subassembly 6, have alleviateed the impact force that unmanned aerial vehicle shank suffered when descending, have increased the life of unmanned aerial vehicle shank.

As a further improvement, telescopic rods 7 are arranged at two ends of each roller 5, each telescopic rod 7 penetrates through the corresponding rotating plate 4, a through hole for the telescopic rod 7 to penetrate through is formed in the rotating plate 4, and the telescopic rods 7 penetrate through the rotating plate 4 and extend outwards. Each roller 5 is in threaded connection with the telescopic rods 7 at the two ends of the roller, a groove 9 is formed in each telescopic rod 7, a convex block 8 is arranged in each through hole, and the convex block 8 is matched with the groove 9. The setting of recess 9 can be to its limiting displacement of telescopic link 7, and when roller 5 drove telescopic link 7 and stretches out and draws back, telescopic link 7 does not carry out the pivoted on rotor plate 4, and telescopic link 7 can to stretching out and drawing back.

Of course, it is also possible to install an electric push rod inside the roller 5 to drive the telescopic rod 7 to extend, but considering that the battery load of the unmanned aerial vehicle is increased, the threaded connection between the telescopic rod 7 and the roller 5 is not good.

Wherein the threads of the two telescopic rods 7 on the same roller 5 are opposite, so that when the roller 5 starts to rotate, the telescopic rods 7 on both ends of the roller 5 can simultaneously extend and retract in the roller 5. What need explain is, when the rotor plate 4 on two shank rotated outwards, roller 5 rotated, and later telescopic link 7 on each roller 5 begins to outwards extend, and at this moment, the impact force that explains unmanned aerial vehicle relative ground is great, and telescopic link 7 stretches out the back outwards, can prevent that unmanned aerial vehicle from because of too big to the impact force on ground, leads to unmanned aerial vehicle to appear empting the problem, causes the accident of unmanned aerial vehicle organism 1 destruction even.

The using method comprises the following steps: at first, adjust its pulling force with rotary drum 603 on the buffering subassembly 6 according to unmanned aerial vehicle's specification, later during unmanned aerial vehicle whereabouts, according to the impact force of unmanned aerial vehicle and ground, the rotor plate 4 begins to revolve the axle and outwards rotates, roller 5 and ground contact begin to rotate, and each telescopic link 7 that is located roller 5 can order about the length of telescopic link 7 outside removal along with the number of turns of rotation of roller 5. And extension spring 601 in the buffering subassembly 6 is stretched by rotor plate 4, plays the effect of buffering and inhaling to the impact force on unmanned aerial vehicle shank and ground by tensile extension spring 601, plays the effect of protection to unmanned aerial vehicle shank.
