Description
Technical field
The present invention relates to unmanned plane undercarriage technical field, in particular to a kind of unmanned plane damping undercarriage.
Background technique
UAV referred to as " unmanned plane ", is manipulated using radio robot and the presetting apparatus provided for oneself
Not manned aircraft, or fully or intermittently automatically operated by car-mounted computer.Compared with manned aircraft, nobody
Machine is often more suitable for the task of those too " slow-witted, dirty or dangerous ".Unmanned plane press application field, can be divided into it is military with it is civilian.
Military aspect, unmanned plane are divided into reconnaissance plane and target drone.Civilian aspect, unmanned plane+industrial application are that unmanned plane has really just needed；
At present take photo by plane, agricultural, plant protection, miniature self-timer, express transportation, disaster relief, observation wild animal, monitoring infectious disease, mapping,
The application in news report, electric inspection process, the disaster relief, movies-making, manufacture romance etc. field, has greatly expanded unmanned plane itself
Purposes, developed country also actively extension industrial application and develop unmanned air vehicle technique.
But the undercarriage material of present unmanned plane is comparatively rigid, poor, landing effect difference hidden danger that there are damping effects,
It even will cause unmanned plane damage, even if normally landing, the damping that effect is not achieved also can be to the accurate instrument carried on unmanned plane
Device causes certain damage.
Summary of the invention
The present invention provides a kind of unmanned plane damping undercarriages, its advantage is that horizontal impact power when can land to unmanned plane
It is buffered with vertical impact force, good damping effect, can effectively protect the equipment carried on unmanned plane.
Above-mentioned purpose of the invention is achieved through the following technical solutions, a kind of unmanned plane damping undercarriage, including with
Perforative center is equipped in the middle part of the connecting plate being mounted on unmanned plane and the bottom plate being arranged in below connecting plate, the bottom plate
Hole, the two sides side wall of the centre bore are equipped with the cushion hole for putting in bottom plate, and the first buffer spring is equipped in the cushion hole, described
The slide post contacted with the first buffer spring is additionally provided in cushion hole, one end that the slide post stretches out cushion hole is rotatably connected to
The other end of connecting rod, connecting rod is rotatably connected on the bottom of connecting plate.
It is different with flight landing angle due to its flying speed through the above technical solutions, when UAV Landing, it has
Impact force on vertical direction and horizontal direction, impact force are transmitted on bottom plate by the first buffer spring, unmanned plane landing
When impact force act directly on connecting plate, slide post is then transferred to by connecting rod, it is sliding in cushion hole after slide post stress
It moves and squeezes the first buffer spring, to play the role of cushion impact forces, reduce vibration, since the both ends of connecting rod are rotation
Connection, thus no matter horizontal impact power on unmanned plane or vertical impact force, can be unloaded by the first buffer spring, therefore
Good damping effect when to UAV Landing can effectively protect the equipment carried on unmanned plane.
The present invention is further arranged to, and the side of the slide post is equipped with sliding slot, and the side wall of the centre bore, which is equipped with, to be put in
The limited block of sliding slot.
Through the above technical solutions, position-limiting action is played in movement of the limited block to slide post in cushion hole, so that slide post
It is not easy to fully slide out cushion hole, improves whole reliability.
The present invention is further arranged to, and one end that the slide post is contacted with the first buffer spring is equipped with and puts in the first buffering
Positioning column in spring.
Through the above technical solutions, on the one hand, positioning column, which is put in, can reinforce the first buffer spring in the first buffer spring
Rigidity, the first buffer spring stress squeeze when be not easy to deform；On the other hand, when the decrement of the first buffer spring is excessive
When, positioning column is contradicted to the bottom of cushion hole, and contradicting the first buffer spring cannot continue to compress, and ensure that spring in large impact
Under be not pressurised failure.
The present invention is further arranged to, and the two sides of the bottom plate are rotatably connected to buffer board, the buffer board and bottom plate it
Between be equipped with the second buffer spring.
Through the above technical solutions, when UAV Landing, buffer board and ground face contact, when buffer board also can be to aircraft landing
Impact force buffered, further increase buffering effect.
The present invention is further arranged to, in the horizontal direction, the telescopic direction of the first buffer spring and the second buffer spring
It is mutually perpendicular to.
Through the above technical solutions, the first buffer spring and the second buffer spring can by the impact force on different directions into
Row buffering, so that the buffering of impact force when this undercarriage lands to unmanned plane is more comprehensive.
The present invention is further arranged to, and the end of the buffer board is set as arc-shaped.
Through the above technical solutions, the position of buffer board and ground face contact is arc-shaped, which delays when being hit
Punching can slide on the ground, to play buffer function.
The present invention is further arranged to, and the connecting plate is equipped with the buckle for connecting unmanned plane.
Through the above technical solutions, snapping connection is one of the most common type mode that unmanned plane is connect with undercarriage, setting
Buckle facilitates the connection with unmanned plane.
In conclusion the beneficial effects of the present invention are as follows:
1. the impact force on multi-direction when the undercarriage in the present invention can be to UAV Landing carries out snubber, can
Horizontal impact power and vertical impact force when to unmanned plane landing carry out absorption buffering, damping effect when to UAV Landing
It is good, it can effectively protect the equipment carried on unmanned plane；
2. structure is simple, manufacture, maintenance are easy；
3. to be detachably connected between unmanned plane, thus can separately fabricated undercarriage carry out assembled or sell, application prospect is wide
It is general.
