In embodiment of the present utility model, described damping is piston type shock-absorbing mechanism, described shell is piston cylinder, described movable part is piston bar portion, described sheathed part is pistons end, thus described movable part and described sheathed part collectively constitute piston, described shock ring is formed along the effect that flexibly supports radially of described piston cylinder between described pistons end and described piston cylinder, described elastic component formed between described pistons end and described piston cylinder along described piston cylinder axial flexibly support effect.Being appreciated that in other implementations, described piston bar portion and described pistons end can be formed in one structure.It is appreciated that in other implementations, host cavity can be formed in described piston cylinder, can arrange in described host cavity or be filled with buffer medium, to improve the damping effect of described damping further.Described buffer medium can be at least one in liquid, solid and gas.
Above-mentioned damping, described shock ring is used flexibly to support on the sidewall of described housing piece, power is flexibly supported with form the width/radial direction along described housing piece between described movable part and described housing piece, so that described movable part can produce the swing of the width/radial direction along described housing piece, or produce the length direction/axially move along described housing piece, so that described damping is when being subject to the external impacts along described housing piece width/radial direction, it is possible to buffer the vibrations produced between described housing piece and described movable part.Meanwhile, meanwhile, described elastic component forms the resist force along described housing piece length direction/axial between described movable part and described housing piece, vibrations therebetween when sliding with the most described housing piece of movable part described in snubber.In sum, above-mentioned damping, it is possible to the jerk of buffering multiple directions, its buffering and damping effect is preferable.
In sum, above-mentioned damping, its elastic component, damping shock absorption part and bolster are arranged on the housing, being formed along the axially arranged axial damping structure of described shell, what described axial damping structure formed the length direction along described shell/axial between described movable part and described shell flexibly supports effect；Meanwhile, described shock ring is arranged on described sheathed part, and forms the radial direction shock-damping structure being radially arranged along described shell, and what described sheathed part formed the width/radial direction along described shell between described movable part and described shell flexibly supports effect；Due to the existence of described axial damping structure Yu described radial direction shock-damping structure, enabling described damping to buffer the jerk of multiple directions, its buffering and damping effect is preferable.And the part of described shell one end of stretching out described shell near described movable part is rigid material, within described movable part can being limited to preset range along the amplitude of fluctuation of the width/radial direction of described shell, thus quickly the positioning and stably of the parts realizing being connected with described damping.
It addition, the buffering dynamics of above-mentioned damping can be controlled by the coefficient of elasticity arranging described damping shock absorption part, described shock ring, described elastic component and/or described bolster, its impulsive force that can carry and buffer is relatively large.In the case of described unmanned vehicle has relatively large load, described damping still can effectively damping.
In the utility model embodiment, described unmanned vehicle is rotor unmanned aircraft, and it is used for carrying the filming apparatus such as camera, video camera and carries out taking photo by plane operation.It is appreciated that described unmanned vehicle can be also used for the work such as ground mapping, Investigating and rescue, aerial monitoring, polling transmission line.It can also be appreciated that described unmanned vehicle can also be fixed-wing unmanned vehicle.
Being appreciated that described damping is not limited in described unmanned vehicle in application, its movable equipment that can also be applied to other or remote-controlled movement device such as automatic driving vehicle, unmanned boats and ships, this specification repeats the most one by one.
Embodiment of above is only in order to illustrate the technical solution of the utility model and unrestricted, although the utility model being described in detail with reference to above better embodiment, it will be understood by those within the art that, the technical solution of the utility model can be modified or equivalent the most should not depart from the spirit and scope of technical solutions of the utility model.Those skilled in the art also can do other change etc. in the utility model spirit and be used in design of the present utility model, without departing from technique effect of the present utility model.These are according to the utility model changes of being done of spirit, all should be included in the utility model claimed within the scope of.
