Description
Technical field
The present invention relates to separation, release unit technical field, dress is automatically disengaged more particularly, to a kind of unmanned plane parachute
Put.
Background technology
Unmanned plane is the abbreviation of UAV, is to utilize radio robot and the presetting apparatus provided for oneself behaviour
Vertical not manned aircraft.The recorery parachute that unmanned plane parachute belongs in parachute, the effect of recorery parachute is to ensure that unmanned plane
Ground is returned securely back to after aerial mission is completed.
The structural representation for the unmanned plane parachute automatic releasing device that Fig. 1 provides for prior art.
At present, unmanned plane parachute automatic releasing device is to land moment in unmanned plane, makes parachute smooth with unmanned plane
The device of separation.Specifically, as described in Figure 1, unmanned plane parachute automatic releasing device of the prior art can include：Shell
11st, inner casing 12, spring 13, safety pin 14, spheroid 15 and connecting rod 16, limiting plate 17 and cylinder 18；Wherein, shell 11
Inside is provided with upper and lower two chambers, and the bottom of the top of epicoele provided with opening, cavity of resorption is provided with opening, inner casing 12 by cavity of resorption opening
Place loads the lower intracavitary of shell 11, and connecting rod 16 vertically loads inside the epicoele of shell 11 by the opening of epicoele, shell 11 with
Connecting rod 16 is provided with corresponding safe pin-and-hole, and safety pin 14 is inserted in safe pin-and-hole, and spring 13 is set with connecting rod 16, on
The limiting stand coordinated with limiting plate 17 is provided between chamber and cavity of resorption, the lower cavity wall of shell 11 is provided with groove, the shell wall of inner casing 12
On be provided with circular hole, the space of groove and circular hole formation is built with spheroid 15, and the bottom of cylinder 18 is cylinder, cylindrical side and spheroid

The distance between the bottom land of arc groove 19 and the inwall of inner casing 12 are more than the diameter of spheroid 15.
The course of work of above-mentioned unmanned plane parachute automatic releasing device of the prior art is：First, parachute is being opened
The moment of umbrella can produce larger impact tension to unmanned plane, in the presence of the impact tension, connecting rod 16 and shell 11
Safety pin 14 can be cut；Then, when unmanned plane lands, the work of connecting rod 16, limiting plate 17 and cylinder 18 in spring 13
With the lower lower motion along axis to inner casing 12；Finally, when arc groove 19 is displaced downwardly at spheroid 15, spheroid 15 is in arc groove 19
Place comes off, so as to promote shell 11 to be automatically separated with inner casing 12, and then drives parachute to be smoothly detached with unmanned plane.
However, when present inventor is had found using above-mentioned unmanned plane parachute automatic releasing device of the prior art,
Because the impact tension that Parachute Opening moment produces is larger, therefore the impact tension is same promote that safety pin 14 cut
When, equally easily cause the damage of unmanned machine equipment；If being avoided damage to by installing buffer unit with reducing impact tension,
Then safety pin 14 again possibly can not be cut so that connecting rod 16, limiting plate 17 and cylinder 18 just can not spring 13 effect
The lower lower motion along axis to inner casing 12, causes parachute can not complete to separate with unmanned plane, in turn results in UAV Landing
Still pulled and slide by parachute afterwards, while unmanned plane scratches the damage that collision still easily causes equipment during dragging with ground
Wound.
