Description
Technical field
The present invention relates to a kind of hinge that locking is impacted that slows down, specifically, described hinge is mainly applicable to boatDeployable structure on it device, the one dimension straight line with interlock requirement as solar wing, antenna etc. launches,Can realize in ensureing that deployable structure launches synchronism, slow down it and launch the impact in rear locking momentLoad, after locking, rigidity is higher; Also can be applicable to civilian mechanical field.
Background technology
Deployable structure is in gathering impaction state in emission process, and what be fixedly mounted on delivery vehicle hasIn effect load cabin, volume minimum. To be launched enter the orbit after, by ground command center's control structure by designing requirementDischarge and launch gradually, become an aerospace works, then lock and remain operation duty. Along withThe develop rapidly of spacecraft, also more and more higher to the requirement of deployable structure, both required deployable structureThe synchronism of expansion process is good, requires again the shock loading in locking moment after launching little, locking will be ensured simultaneouslyAfter rigidity want high. The Spring driving linkage of applying on hinged development agency in existing space deployable structure,Only possess the requirement that ensures expansion process synchronism, can not play and slow down the shock loading of launching the rear locking momentFunction, the rigidity after the linkage of traditional locking slot type launches locking can not meeting spatial deployed configurationThe demand of higher stiffness.
Summary of the invention
Can not meet in guarantee space in order to solve the linkage of deployable structure on existing spacecraft simultaneouslyWhen deployable structure launches synchronism, slow down it and launch the shock loading in rear locking moment, and tool after lockingThere is the defect that higher stiffness requires, the object of the present invention is to provide a kind of hinge that locking is impacted, institute of slowing downState hinge to be mainly applicable on spacecraft launching synchronism and launching that locking shock loading all has higher requirementsDeployable structure, as solar wing, antenna etc., can realize and to ensure that deployable structure launches synchronismMeanwhile, after slowing down its shock loading of launching the rear locking moment and locking, rigidity is higher.
The object of the invention is to be achieved through the following technical solutions.
Slow down the hinge that locking is impacted, described hinge is primarily of centre drawer hinge bracket, centre drawer hinge, shift fork, lockingFork, coupled wheel, scroll spring, shift fork push rod, lock hook, hinge rotating shaft, locking fork locking post,Shift fork locking post, locking groove, coupled wheel lug, lock hook rotating shaft, shift fork rotating shaft and scroll spring outer ringFixed axis composition.
Wherein, centrally the plane of symmetry is symmetrical installs and be connected by hinge rotating shaft for centre drawer hinge bracket and centre drawer hinge, can be aroundHinge rotating shaft relatively rotates, and hinge rotating shaft is fixedly connected with centre drawer hinge.
Centre drawer hinge bracket inner side is provided with lock hook, and the Central Symmetry face of lock hook and centre drawer hinge bracket is coplanar, and lock hook passes throughLock hook rotating shaft is connected with centre drawer hinge bracket, and front end is hook-shaped; Lock hook can be relative around lock hook rotating shaft with centre drawer hinge bracketRotate, lock hook rotating shaft is provided with lock hook torsion spring, to retrain lock hook around lock hook rotating shaft with respect to public affairsThe rotation of hinge; Shift fork push rod tail end is fixedly connected on centre drawer hinge bracket outside on one side; Scroll spring is fixedly mounted onAnother side outside centre drawer hinge bracket, the inner ring of scroll spring is fixedly connected with hinge rotating shaft, outside outer ring and scroll springCircle fixed axis is fixedly connected with, and scroll spring outer ring fixed axis is fixedly connected with centre drawer hinge bracket.
Centre drawer hinge inner side is provided with locking fork, and the Central Symmetry face of locking fork and centre drawer hinge is coplanar, locking pendulumBar is fixedly connected with hinge rotating shaft, and front end is provided with locking fork locking post. Shift fork is by shift fork rotating shaft and female hingeChain outside is connection on one side, and shift fork rotating shaft is provided with shift fork torsion spring, with retrain shift fork around shift fork rotating shaft with respect toThe rotation of centre drawer hinge, shift fork front end is provided with shift fork locking post; Shift fork and shift fork push rod are at grade. ConnectionDriving wheel is positioned at shift fork outside, is enclosed within hinge rotating shaft by axle sleeve, and coupled wheel part edge protrudes and forms interlockWheel lug, coupled wheel lug is provided with locking groove; When described hinge is in gathering impaction state, shift forkUnder the effect of shift fork torsion spring, the fork locking post of its front end can insert in locking groove and lock, and makes coupled wheel with femaleHinge is fixedly connected to form interlock.
Preferably be fixedly connected with adjusting screw(rod) in locking fork inner side.
The further relative position relation of hinge each several part of the present invention can be soft by ADAMS motion simulationPart designs according to demand.
In the described hinge course of work, when being in draw impaction state in, centre drawer hinge bracket is relative with centre drawer hinge to be turned overCertain angle, makes scroll spring have certain predeformation with storage elasticity potential energy, for described hinge provides expansionDriving moment; The shift fork locking post of shift fork its front end under the effect of shift fork torsion spring inserts in locking groove locks,Coupled wheel and centre drawer hinge is made to be fixedly connected to form interlock. After hinge draws compression releasing in, described scroll springThe elastic potential energy storing discharges, and drives centre drawer hinge bracket and centre drawer hinge to relatively rotate and launches, in expansion process,Before locking fork contact lock hook, shift fork push rod contacts and promotes shift fork with shift fork, make shift fork lock post fromIn locking groove, deviate from release, remove the linkage function of coupled wheel and centre drawer hinge, thus make to launch locking belowTime the hinge impact energy that is subject to can not to other hinge transmission of coupled wheel connection, thus slow down other hingesThe shock loading being subject to. After shift fork locking post is deviate from release from locking groove, hinge continues to launch, and makesLocking fork contact lock hook also promotes lock hook around lock hook axis of rotation, and locking fork is transported along lock hookDynamic, until locking fork enters the hook-shaped position locking of lock hook front end, the lock hook torsion spring of lock hook produces simultaneouslyRaw moment of torsion limits the motion in described hinge gathering direction, and the two acts on the final lock that achieves hinge simultaneouslyFixed.
Adjusting screw(rod) front end contacts with centre drawer hinge bracket, limits the motion of expansion direction, described in can ensureing furtherThe expansion locking of hinge.
Beneficial effect
