Description
Technical field
The present invention relates to scissor mechanism field, particularly relate to a kind of mechanical deployable structure having radian.
Background technology
Scissor mechanism has at present and is widely applied very much and develops, as folding tent, contractile door curtain,
Elevator, foldable desk lamp or mechanical arm etc..Its feature is that magnification is big, and extensible distance is with big
Span, and it is the least to be taken up space after it shrinks, and is therefore applied in many industries.
The application of current most of scissor mechanism uses the scissors machine of one side scissor mechanism or double flat row
Structure, as door curtain uses one side scissor mechanism, elevator uses the scissor mechanism of double flat row.Mostly
The major defect of scissor mechanism of number is by under multi-direction power effect, the intensity of the structure on its Impact direction
Being not enough to bear the load-bearing effect of this power with rigidity, be susceptible to askew folding, safety is the highest.Additionally, mesh
The load-carrying ability of front scissor mechanism is the highest, and existing scissor mechanism seldom has the scissors machine of radian
Structure, even if there being radian these weakness the least to limit its wider application.
Summary of the invention
It is an object of the invention to propose a kind of mechanical deployable structure having radian, expand the radian of development agency,
Thus expand it should scope.
For reaching this purpose, the present invention by the following technical solutions:
A kind of mechanical deployable structure having radian, its deployable structure being made up of connecting rod assembly；Described connection
Bar assembly is made up of many secondary straight V shape rod members and the alternately head and the tail pivot joint of bent fork formula rod member；Described head and the tail pivot points
The first articulated section for described connecting rod；Every secondary described straight V shape rod member is by two straight connecting rods intersection pivot joints
Become；Every secondary described bent fork formula rod member is formed by two curved connecting rods intersection pivot joints；Described intersection pivot points is
Second articulated section.
Preferably, two groups or more described connecting rod assembly is connected by connector and can form one and be cased with radian
Telescopic development agency；Two overlap described connecting rod member parallel lays, middle by connector pivot joint；
When described deployable structure stretches, the path of walking is curve.
Preferably, two overlap described connecting rod member parallel lays, and described first articulated section of relevant position is by even
Fitting pivot joint.
Preferably, two overlap described connecting rod member parallel lays, and described second articulated section of relevant position is by even
Fitting pivot joint.
It is further preferred that described connector is straight rod member.
Preferably, same described connecting rod, the connecting rod part on described second both sides, articulated section is symmetrical.
Preferably, the described connecting rod length of described development agency is equal.
The present invention, by utilizing straight V shape rod member and the deployable structure having radian of bent fork formula rod member composition, expands
The radian of development agency, the range making development agency is wider, and by overlapping connecting rod assembly and company more
Development agency rigidity and the intensity of fitting composition are more preferable, and safety in utilization is more preferably.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the present of invention；
Fig. 2 is the structural representation of one of which development agency of the present invention；
Wherein: 1 is straight V shape rod member, 2 is bent fork formula rod member, and 10 is straight connecting rods, and 20 is curved connecting rod,
3 is the first articulated section, and 4 is the second articulated section, and 5 is connector.
Detailed description of the invention
Further illustrate technical scheme below in conjunction with the accompanying drawings and by detailed description of the invention.
As it is shown in figure 1, a kind of mechanical deployable structure having radian, its knot opened up being made up of connecting rod assembly
Structure；Described connecting rod assembly is made up of many secondary straight V shape rod members 1 and bent fork formula rod member 2 alternately head and the tail pivot joint；
Described head and the tail pivot points is the first articulated section 3 of V shape rod member；Every secondary described straight V shape rod member is direct-connected by two
Extension bar 10 intersects pivot joint and forms；Every secondary described bent fork formula rod member is intersected pivot joint by two curved connecting rods 20 and forms；
Described intersection pivot points is the second articulated section 4.
Described straight V shape rod member and described bent fork formula rod member constitute the development agency with radian, such can
The radian of the development agency that the radian of exhibition mechanism forms compared with whole bent fork formula rod members is big, so just can expand
The range of application of big development agency.
As in figure 2 it is shown, two groups or more described connecting rod assembly is connected by connector 5 can form one
It is cased with the telescopic development agency of radian；Two overlap described connecting rod member parallel lays, middle by connecting
Part 5 pivot joint；When described development agency stretches, the path of walking is curve.
Described development agency is under the regulation of extraneous drive system, toward a direction simultaneous retractable and development agency
The path of stretching operation is curve, and the machinery support being suitably for having certain altitude level uses；And so
Development agency can adapt to that different levels are flexible to be used for greater flexibility, and the radian of curve is relatively big, all enhances
While the two set rigidity of development agency, intensity and safety in utilization, expand the range of development agency.
Preferably, two overlap described connecting rod member parallel lays, and described first articulated section 3 of relevant position leads to
Cross connector 5 pivot joint.In two set development agencies, the quantity of the first articulated section 3 is more than the second articulated section 4
Quantity, is fixed by the first articulated section 3, and structure is more stable, and rigidity is bigger.
Certainly, also having another scheme, two overlap described connecting rod member parallel lays, relevant position described
Second articulated section 4 is by connector 5 pivot joint；Being connected by the second articulated section 4, the structure of package unit is more
Simply, it is adaptable to the load of some lightweights.
Further, described connector 5 is straight rod member, and simple in construction, cost is the highest.
Further, same described connecting rod, the connecting rod part on described second both sides, articulated section 4 is mutual
Symmetry, structural stability is more preferable.
The know-why of the present invention is described above in association with specific embodiment.These describe and are intended merely to explain this
The principle of invention, and limiting the scope of the invention can not be construed to by any way.Based on herein
Explaining, those skilled in the art need not pay performing creative labour can associate other tool of the present invention
Body embodiment, within these modes fall within protection scope of the present invention.
