Description
Technical field
The invention belongs to beanpod pole technology fields, and in particular to a kind of storage of beanpod bar and expanding unit.
Background technique
Carbon fibre composite beanpod bar, abbreviation beanpod bar is a kind of light weight, rigidity is larger, gathering is high-efficient, expansion
The reliable deployable tubulose rod structure of process, it generallys use carbon fibre composite and is made, and is that one kind can flatten volume
The thin-walled tubular rod structure that song collapses.When gathering, beanpod bar can be wound on flattened on roller or itself is rolled into cylinder and is formed
Rounding state；And when being unfolded, it is long that beanpod bar can revert to monosymmetric bis- " Ω " shapes from flat volume state by natural resiliency
Tubulose.Therefore, beanpod bar efficiently solve common support structure storage efficiency it is lower, collapse volume it is larger, structure is complicated, expansion
The problems such as stability and reliability are low provide new technology hand for the development of the deployable support construction of large scale spacecraft
Section is a kind of fundamental space unfolded structure for having and value being widely applied.
Beanpod bar is developed by German Aerospace Center (DLR) at first, later US National Aeronautics and Space Administration (NASA), Russia sieve
This, Japan Aerospace Exploration and Development Agency (JAXA) etc. also all developed this class formation.This kind of beanpod rod structure is before transmission
Coil and collapse, molding is unfolded after entering the orbit, thus needs to design a set of suitable storage and expanding unit, realize its efficiently storage and
The function being smoothly unfolded.Document " Gossamer-1:Mission concept and technology for a
controlled deployment of gossamer spacecraft》(Advances in Space Research,
2017, Vol.59, pp.434-456, doi:10.1016/j.asr.2016.09.022) report a kind of beans researched and developed by DLR
The storage of pod bar and expanding unit (unit is unfolded in referred to as Boom and Sail Deployment Unit, bar sail), the work of the device
It is as principle: the stainless steel strip of a 0.03mm thickness is crimped together with the beanpod bar after flattening be collected in device in advance
It is interior, which is recycled by driving motor, frictional traction is formed to beanpod bar, to realize the exhibition of beanpod bar.The device
Structure is complex, needs whole process to be assisted manually when storing beanpod bar, and to realize between metal tape and beanpod bar
Good fit curling is more difficult, additionally due to beanpod bar collection reel and driving motor be not in same position, there is also height
Relatively large sized deficiency on direction.
Document CN 106527499A (application number: 201611107560.2, denomination of invention: a kind of variation rigidity development agency and
Its investigating method) it also proposed a kind of beanpod unfolding mechanism, it is rotated by motor driven roller, makes the beanpod being wrapped on roller
Bar travels forward and is unfolded, but is acted in beanpod bar by guide roller and become flat place by compression, due to needing what is overcome to rub
It is larger to wipe power, and motor can not provide effective tractive force, thus the exhibition of actually beanpod bar is very difficult, is easy to appear card

Motor 31 is allowed to work in co-rotating mode, motor output shaft 33 is rotated in the clockwise direction at this time.In this case, expansion transmission
Component 50 will not be driven by reverse driving pawl mechanism 60, i.e., rolling shaft 42 will not the exhibition of active drive beanpod bar 80；But motor
Output shaft 33 can be occurred clockwise by the transmission of the second ratchet 71 in forward driving ratchet mechanism 70 come band movable reel 21
Rotation, and then realize beanpod bar 80 is accommodated on reel 21.
It is worth noting that, as the active of reel 21 rotates, rolling shaft 42 is also realized beanpod bar during storage
80 functions of flattening, during this, rolling shaft 42 can also occur passively to rotate.
2, process is unfolded
Operating voltage is connected, allows motor 31 to work in reversing mode, motor output shaft 33 rotates in the counterclockwise direction at this time.
In this case, reel 21 will not be positively driven the driving of ratchet mechanism 70, i.e., the rotation of active will not occur for reel, but inverse
To driving pawl mechanism can by drive driving wheel rotation, driving wheel so drive expansion transmission component in driven wheel and
Rolling shaft gear rotates, so that rolling shaft be driven to rotate.The specific rotation direction of four rolling shafts is as shown in figure 14, and two
Lower rolling shaft will be rotated in the clockwise direction, and two upper rolling shafts will rotate in the counterclockwise direction.Pass through four rolling shafts
It is rotatably assorted and provides expansion tractive force for beanpod bar, gradually put on display beanpod bar from reel to realize.
The design that the present invention is arranged due to using motor along the central axes of the reel for storing beanpod bar, device
Overall volume it is smaller, be especially reduction of the size of short transverse；The present invention also passes through driving while can flatten beanpod bar
Rolling shaft rotation drive beanpod bar to put on display, effective exhibition tractive force can be provided for beanpod bar, avoid the stuck feelings of beanpod bar
The generation of condition；In addition, the present invention realizes that the torque by the same motor is output to expansion by the way that two sets of ratchet mechanisms are arranged respectively
On rolling shaft and on the reel of storage, so that designed device is provided simultaneously with the function of electric stowing Yu electronic expansion
Energy.
The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all at this
Under the inventive concept of invention, using equivalent structure transformation made by description of the invention and accompanying drawing content, or directly/use indirectly
It is included in other related technical areas in scope of patent protection of the invention.
