Description
Technical field
The present invention relates to a kind of latent apparatus of the inflatable balance of change born of the same parents that is applied to microminiature underwater robot.
Technical background
Because when robot moves under water, be in three dimensional space, adjust in its attitude, run into unstable environment, as rapid current, stormy waves, and for the under-water robot that manipulator is arranged, when manipulator grasps load, because the influence of antagonistic force, robot is easy to lack of equilibrium and influences its underwater operation, research in the past is attitude adjustment and the balance that realizes robot by propelling unit or the rudder wing, but its control system is very complicated, and the adjustment time is long, and need manual intervention usually, can't accomplish Adjustable real-time.
Traditional theory of mechanisms theory is based on member and the kinematic pair of fixed number, and mechanism has only fixing degree of freedom.Become oneself's combination and self-reconstruct that born of the same parents mechanism is based on mechanism, compare with the fixing traditional mechanism of degree of freedom with having only the fixed number member, but change born of the same parents mechanism has variable freedom and variable number of components.Become born of the same parents mechanism and be the key concept that scholar in recent years proposes, it is defined as, and is in service continuously in mechanism, is changed by effective rod member number or kinematic pair type and geometric relationship and causes the change in topology of mechanism, and cause mechanism's mobility to change; In service continuously in mechanism, have at least a mobility to change, and after mobility changed, mechanism still kept operation.
Becoming born of the same parents mechanism is a kind of novel mechanism that presents different degree of freedom and number of components in different phase, flexible change born of the same parents mechanism has more flexibly, deformable super performance, thereby will become born of the same parents mechanism and be applied to under-water robot, realize the autonomic balance of robot, will have excellent research and be worth and realistic meaning.
Summary of the invention
The objective of the invention is to propose the latent apparatus of the inflatable balance of a kind of change born of the same parents, the external interference situation that it can be subjected to according to under-water robot inflation and bleeding in the elastic bag, realize expansion and the contraction of elastic bag, the position of gas transfer, thereby change the under-water robot part and be subjected to the buoyancy size, produce different moments, the impact of opposing external environment is disturbed, and realizes the autonomic balance of under-water robot.
For realizing above purpose, the present invention is achieved through the following technical solutions:
The inflatable balance of a kind of change born of the same parents apparatus of diving, comprise inflator mechanism, four expansion links, become born of the same parents' slide block mechanism, umbrella shape mechanism, elastic bag, inflator mechanism is by inflator, piston, piston push rod, air cylinder cover constitutes up and down, and air cylinder cover is separately fixed at the two ends of inflator up and down, piston is installed in the inflator, can slide up and down in inflator, piston push rod one end is fixed on the piston, and the other end passes down air cylinder cover and is connected with actuating device-slider-crank mechanism; Four telescopic rods are made of an arm and an elongate rod respectively, similar " fishing rod " structure, arm one end has four well-distributed sulculuses, be convenient to gas communication, elongate rod can relative motion in arm, when expansion link is elongated to extreme length, can transmit pulling force between elongate rod and the arm; Become born of the same parents' slide block mechanism by slide block, main shaft, spring and four bows constitute up and down, four bows hinge in twos are connected to form two pairs of curved rods, the two pairs of curved rod two ends form hinge with slide block up and down respectively and are connected, being 180 degree is symmetrically distributed, slide block is installed on the main shaft up and down, all can slide up and down along main shaft, spring housing freely is positioned over up and down between the slide block on main shaft; Umbrella shape mechanism is made of limiting stopper, four arc struts and four connecting rods, and four arc strut one ends are connected with the limiting stopper hinge, is 90 degree and arranges that evenly four connecting rods are connected with a bow hinge separately, constitutes umbrella frame frame shape structure; Elastic bag is covered on four arc struts, captives joint with sliding block with limiting stopper, constitutes the sphere structure of a sealing.
Four elongate rod one ends of four expansion links are captiveed joint with piston, are 90 degree and evenly distribute, and four arms pass air cylinder cover captives joint with sliding block, are 90 degree and evenly distribute; Main shaft one end that becomes born of the same parents' slide block mechanism is fixed on the air cylinder cover its axis and inflator dead in line; The limiting stopper of umbrella shape mechanism is threaded fixing with the other end of main shaft, (hinge is connected, and is 90 degree and evenly distributes with top shoe in four companies; The length of elongate rod is less than the length of arm, and the elongate rod diameter is convenient to gas and is circulated by arm less than a bore.
During work, actuating device driven plunger push rod promotes the piston upward movement, piston promotes slide block upward movement up and down by four expansion links, begin simultaneously to inflate to elastic bag, beveled structure launches, when top shoe touched limiting stopper, top shoe stopped upwards to slide, and became born of the same parents' slide block mechanism and became born of the same parents, become one degree of freedom by before two degree of freedom, the effective exercise member becomes three by two, when piston continues upward movement, promotes top shoe by expansion link and upwards slides, the spring of slide down interblock is compressed, curved rod outwards launches, up to the elastic bag inflation, and the piston stop motion.In motion process, gas is transferred in the elastic bag in inflator, and elastic bag is from being retracted to abundant expansion, and buoyancy moment increases.Expansion link can make the stroke of piston greater than the stroke of sliding block, thereby the gas in the inflator is fully transferred in the elastic bag, and elastic bag is fully expanded.
The present invention compares with present technology, has following apparent outstanding substantive distinguishing features and remarkable technological advance:
1 compares with traditional under-water robot balancing technique, and this structure adopts mechanical mechanism, and is simple in structure, and the control system of no very complicated is more easy to control, the stability height.
2, will become born of the same parents mechanism and apply to under-water robot, because under-water robot works under water, be subjected to the hydraulic pressure effect, and become born of the same parents mechanism and can make mechanism present different motion process orders at stroke during with backhaul, thereby satisfy the balance underwater actual demand of apparatus of diving.
