Description
Technical field
The present invention relates to separation, disconnecting gear technical field, especially relate to a kind of unmanned plane parachute automatic releasing device.
Background technology
Unmanned plane is the abbreviation of robot airplane, is the not manned aircraft utilizing radio robot to handle with the process controller provided for oneself.Unmanned plane parachute belongs to the recorery parachute in parachute, and the effect of recorery parachute to ensure that unmanned plane gets back to ground safely after completing aerial mission.
The structural representation of the unmanned plane parachute automatic releasing device that Fig. 1 provides for prior art.
At present, unmanned plane parachute automatic releasing device lands moment at unmanned plane, makes the device that parachute and unmanned plane are separated smoothly.Particularly, as described in Figure 1, unmanned plane parachute automatic releasing device of the prior art can comprise: shell 11, inner casing 12, spring 13, safety pin 14, spheroid 15 and pipe link 16, positioning plate 17 and cylinder 18, wherein, the inside of shell 11 is provided with, lower two chambeies, the top of epicoele is provided with opening, the bottom of cavity of resorption is provided with opening, inner casing 12 loads in the cavity of resorption of shell 11 by the opening part of cavity of resorption, the epicoele that pipe link 16 vertically loads shell 11 by the opening part of epicoele is inner, shell 11 and pipe link 16 are provided with corresponding safe pin-and-hole, safety pin 14 inserts in safe pin-and-hole, pipe link 16 is set with spring 13, the limit dais coordinated with positioning plate 17 is provided with between epicoele and cavity of resorption, the cavity of resorption wall of shell 11 is provided with groove, the shell wall of inner casing 12 has circular hole, the space that groove and circular hole are formed is built with spheroid 15, the bottom of cylinder 18 is cylinder, cylindrical side contacts with spheroid 15, cylindrical tip is connected with round platform, round platform top is connected with positioning plate 17, the side face of round platform has arc groove 19, and the distance between the inwall of the bottom land of arc groove 19 and inner casing 12 is greater than the diameter of spheroid 15.
The working process of above-mentioned unmanned plane parachute automatic releasing device of the prior art is: first, parachute can produce larger impact tension to unmanned plane in the moment of parachute-opening, under the effect of this impact tension, safety pin 14 can be cut off by pipe link 16 and shell 11; Then, when unmanned plane lands, pipe link 16, positioning plate 17 and the lower motion of cylinder 18 along axis to inner casing 12 under the effect of spring 13; Finally, when arc groove 19 is displaced downwardly to spheroid 15 place, spheroid 15 comes off at arc groove 19 place, thus impels shell 11 to be automatically separated with inner casing 12, and then drives parachute to be separated smoothly with unmanned plane.
But, when present inventor finds to use above-mentioned unmanned plane parachute automatic releasing device of the prior art, the impact tension produced instantaneously due to Parachute Opening is comparatively large, and therefore this impact tension is while impelling safety pin 14 to be cut off, and equally easily causes the damage of unmanned plane equipment; If avoid damage to reduce impact tension by installing shock absorber, then safety pin 14 possibly cannot be cut off again, thus pipe link 16, positioning plate 17 and cylinder 18 just cannot lower motion along axis to inner casing 12 under the effect of spring 13, cause parachute cannot complete with unmanned plane to be separated, and then still pulled slip by parachute after causing UAV Landing, simultaneously unmanned plane collides with ground scratching the damage still easily causing equipment pulling in process.
