Description
Technical field
The invention belongs to field of aerospace technology, especially a kind of drag-line drives anti-singular point hinge.
Background technology
With the development of space technology, space development agency such as solar energy sailboard, Large deployable antenna etc. navigate in aviation
Its field is widely used.Hinge directly affects the extensibility of mechanism as the articulating component of development agency
Can, or even decide the success or failure of space mission.By continuing to optimize to structure, material etc., space development agency gradually towards
Large scale, light-weighted direction are developed, and then higher requirement is proposed in terms of rigidity, quality, reliability to hinge.
Hinge typically completes expansion motion as the joint component of development agency by drag-line or Spring driving.For
The high storage rate requirement of space development agency is met, has rod member axially in parallel at hinge during mechanism rounding state.This will cause
When being driven by drag-line merely, hinge is allowed to deploy, i.e. the singular point (dead point) of hinge is asked only by axial force without radial load
Topic.
The method for overcoming hinge singular point at present is the method combined using Spring driving and drag-line driving, attached at hinge
Plus torsion spring structure, the elastic potential energy for deforming storage by torsion spring drives hinge expansion to overcome dead point, then again by drag-line come
Control the expansion of hinge.Such a method can efficiently solve the dead unit problem of hinge, complete hinge expansion, but be the increase in bullet
Spring driving structure, makes hinge arrangement is more complicated, become large-sized, quality increases, deploy reliability to reduce；The unexpected exhibition of torsion spring
Open, larger impact is caused to overall structure；, will due to the difference of torsion spring parameter for there is the deployable structure of multiple hinges
Introduce expansion error.
The content of the invention
Instant invention overcomes shortcoming of the prior art anti-singular point hinge is driven there is provided a kind of drag-line.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions：
A kind of drag-line drives anti-singular point hinge, including T-shaped hinge, synchronising hinge, horizontal tappet, vertical tappet and

Bar and vertical tappet, drag-line is provided with expansion link and T-shaped hinge；
It is servo-actuated that the T-shaped hinge includes hinge mount, zip commutating structure, drag-line tensioning wheel, flexible joint element for bar and level
Joint element for bar, hinge mount is bilateral symmetry, and the centre position of hinge mount is provided with zip commutating structure, in hinge mount side
Drag-line tensioning wheel, flexible joint element for bar and horizontal tappet are respectively symmetrically provided with by middle part to both sides on plate；Drag-line tensioning wheel
By erect straight arranged top sheave constituted with lower sheave, for drag-line between flexible joint element for bar and zip commutating structure transition and to
Push and strain at rope, first pulley and second pulley are provided with flexible joint element for bar；
Moreover, the zip commutating structure is made up of support member and reversing shaft, reversing shaft is arranged on support member, support member
It is fixed in by screw on hinge mount, zip commutating structure is used for the commutation for realizing zip, and can prevent from departing from hinge when drag-line from commutating
Chain mid-plane, influences the unobstructed of drag-line；
Moreover, in the flexible joint element for bar, first pulley is located at the top of second pulley, first pulley is slided by first
Wheel fixing axle is installed on flexible joint element for bar, and second pulley is installed on hinge mount side plate by second pulley fixing axle；
Moreover, the horizontal tappet is arranged at the outermost of hinge mount side plate, the company for tappet and T-shaped hinge
Connect, tappet is deployed under the drive of expansion link.
Overcome the initial singular point principle of hinge：In T-shaped hinge, drag-line sequentially passes through flexible joint element for bar, drag-line tensioning
Wheel and zip commutating structure, are set as two fixing points by the second pulley in drag-line tensioning wheel, flexible joint element for bar, stretch
First pulley in joint element for bar is set as free point.Initial time, when drag-line pass through T-shaped hinge after, two fixing points and from
One acute triangle will be formed by point.Torque, which will be produced, under the effect of free point both sides cable-tension, at free point carrys out band
Its rotation is moved, that is, solves the problems, such as initial singular point.
Compared with prior art, the beneficial effects of the invention are as follows：
(1) the expansion torque at expansion link is formd by the effect of stretch joint element for bar and drag-line tensioning wheel, effectively
Initial singular point of the hinge in the case of drag-line driving is solved the problems, such as, the expansion reliability of hinge is improved and reduces energy
Consumption；
(2) by simplifying hinge arrangement, complexity is instead of with the pulley added in drag-line tensioning wheel and flexible joint element for bar
Spring driving structure, efficiently reduce the volume and quality of hinge；
(3) hinge drives the controllability and stationarity for improving expansion process only with drag-line without Spring driving.
