Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Embodiment: see Fig. 1-3.
A kind of air bag canopy jettison mechanism, comprise hatchcover 4, left and right fuselage 5,6, be arranged on the air bag 13 of hatchcover 4 upper surface near right fuselage 6 side, the lid mouth down of air bag 13, one end and the left fuselage 5 of hatchcover 4 overlap, and the other end is connected with right fuselage 6 by latch lock unit 3, and described latch lock unit 3 comprises sleeve 7, bolt head is connected with the guide hole longitudinal sliding motion of sleeve 7 bottom, bolt pommel is connected with hatchcover 4 locking bolt 10 and the lock pin 11 be horizontally set in sleeve 7 and pre-tightening apparatus thereof; The side of described locking bolt 10 bolt head is provided with hemispherical groove, and the plunger of lock pin 11 is hemispherical,
When hemispherical plunger inserts the hemispherical groove of locking bolt 10, hatchcover 4 is locking state,
When hemispherical plunger departs from the hemispherical groove of locking bolt 10, hatchcover 4 is released state.
One end of described hatchcover 4 is provided with fixture block 1, and left fuselage 5 madial wall is provided with groove, and fixture block 1 and groove overlap.
The pre-tightening apparatus of described lock pin 11 comprises and is set in lock pin 11 bearing pin spring 8 with it, the forward and backward baffle plate 14,15 spacing with spring 8 two ends;
Described sleeve 7 one end is open design, its inside is longitudinally arranged with two locking boss, front apron 14 is located at locking boss and is kept right the side of fuselage 6, backboard 15 side and right fuselage 6 affixed, opposite side is connected with sleeve 7 open-mouth, lock pin 11 one end is through front apron 14 center affixed, and the middle guide hole of the other end and backboard 15 and right fuselage 6 is slidably connected; It is the extendable room of spring 8 between forward and backward baffle plate 14,15.
The bolt handle of described locking bolt 10 is connected with hatchcover 4 by connector 12.
The connecting plate 2 be connected with hatchcover 4 is provided with in the bottom of described locking bolt 10 bolt handle.
The inwall of described sleeve 7 opening end is provided with the bearing 9 be connected with backboard 15.
Locking process: first connection fixture block 11 is sticked in the groove of fuselage 5, after fixture block 1 sticks into, pull the lock pin 11 in sleeve 7, spring 8 compresses, and inserts locking bolt 10, now unclamp lock pin 11 at the guide hole place, bottom of sleeve 7 opposite side, because the reaction force of spring 8 produces pretightning force to lock pin 11, the spherical plunger clamping of locking bolt 10 hemispherical groove and lock pin 11 is locked, and because hatchcover 4 and air bag are conducted oneself with dignity less, only needs the gravity overcoming air bag 13 and hatchcover after installation.
Releasing process: first air bag lid 16 is opened, air bag starts downward expansion, hatchcover 4 is driven to move down, now, locking bolt 10 moves down, locking bolt 10 bolt head is hemispherical groove structure again, lock pin 11 plunger is spherical, therefore power is decomposed by sphere, and its releasing force is less, under the continuation effect of expansive force, lock pin 11 and locking bolt 10 start to depart from, meanwhile, the fixing point around itself and left fuselage 5 rotates by hatchcover 4, and fixture block 11 departs from fuselage groove, under the continuation effect of bag expansion force, the final and fuselage of hatchcover 4 departs from.
The utility model cancels the unlock drive device of extra hatchcover, directly uses expansive force during airbag deployment that latch lock unit is unlocked, and realizes hatchcover and body departs from airbag deployment motion process.
