Abstract
The invention provides a permanent-magnet-maintenance bistable execution mechanism which adopts a series magnetic circuit and possesses a three-dimensional turning actuation function. A pedestal of the execution mechanism is made of a magnetic conductive material. Two permanent magnets are installed on inner sides of two vertical walls. A slideway is installed on a boss and an armature is arranged in the slideway. A coil, a change-over switch and a power supply are connected in series so as to form a closed loop. A driving lever is installed on a side wall of the armature and is extended through a through hole slot on the side wall of the slideway. One end of a lever in a turning actuation mechanism is provided with an opening groove. The driving lever can be slide in the opening groove. The other end of the lever is extended out of an opening of a side surface of a sleeve and contacts with a chassis of an axon. The axon can be extended out of a top hoe of the sleeve. The permanent-magnet-maintenance bistable execution mechanism adopts a series magnetic circuit structure. An amount of a permanent magnet is small. A volume is small and the permanent magnet is flattening so that parallel motion of the armature can be converted into other motion modes. An application scope is wide. The mechanism is suitable for an occasion which has a three-dimensional or special motion demand and the occasion in which placing space is restricted.

Embodiment
Below in conjunction with Fig. 1 to 4 embodiment, the present invention will be further described in detail.
Permanent magnetism of the present invention keeps bistable state actuator as shown in figs. 1 and 3, and it comprises base 1, permanent magnet 2, armature 3, coil 4, slideway 5, driving lever 8, travel switch 6, reversing switch 12 and power supply E.Base 1 comprises base plate, two side vertical walls and central boss, and boss is positioned in the middle of two perpendicular walls.Both sides permanent magnet 2 is separately fixed at the inner side of base 1 left right vertical wall, and same polarity in opposite directions.Slideway 5 is fixed on the boss of base 1, and boss is all stretched out at two ends, and center line overlaps substantially with the center line of two permanent magnets 2.Armature 3 is placed in slideway 5.Coil 4 is wound in outside the extension of boss two side slideways 5 in the same way, and is connected with power supply E through reversing switch 12.Armature 3 respectively with two stable states of two permanent magnets, 2 adhesive Shi Weigai actuators, it relies on reversing switch 12 to change the sense of current in coils 4, makes armature 3 change polarity, to another stable position, slides, and realizes two switchings between stable state.Driving lever 8 is cylindrical, is fixedly mounted on the sidewall of armature 3, from the through-hole groove of slideway 5 sides, stretches out.Travel switch 6 left and right each one, all, between the boss and perpendicular wall of base 1, be fixed on base plate, and all access reversing switch 12.When armature 3 approaches arbitrary stable position, all can trigger travel switch 6, deenergization E, enters static often open, stablize self-sustaining condition, no longer consumed energy automatically.Travel switch 6 can adopt mechanical type, photoelectric type, Hall-type etc.
Permanent magnetism of the present invention keeps bistable state actuator also to comprise special break-in actuation mechanism, for the parallel motion of armature being converted to other Arbitrary 3 D forms of motion.As shown in Figures 2 and 4, described break-in actuation mechanism comprises lever 7, aixs cylinder 10, spring 11 and sleeve 9.The parallel motion of armature 3 is converted to moving both vertically of aixs cylinder 10, and aixs cylinder 10 has stretches out and two stable states that bounce back, and also forms aixs cylinder formula clutch.In like manner, also can realize other clutch modes such as friction, dental inlay.Lever 7 is a rigidity pole, its breakover point is balance pivot, there is an open slot one end of lever 7, driving lever 8 is through open slot, and described open slot has a level turnover away from one end of regulations and parameters fulcrum, when driving lever 8 moves to after this return portion, lever is vertically by locked, no longer occur cutting down the horizontal applied force of magnetic pull, in like manner, return portion also can design other lock modes such as ratchet, stage clip; Lever 7 other ends stretch into sleeve 9 and contact with aixs cylinder 10 bottom surfaces.Sleeve 9 is the hood-like object of cylinder of a steel top perforate, and there is opening its side.Aixs cylinder 10 is a band chassis cylinder, and on aixs cylinder 10 cylinders, cover has spring 11, and both are all positioned at sleeve 9, and aixs cylinder 10 can be stretched out from the topped hole of sleeve 9, spring 11 and aixs cylinder 10 chassis and sleeve 9 top butts.Spring force is guaranteed described disengaging type actuation mechanism incision steadily, keeps strong, separated quick.
Permanent magnetism of the present invention keeps the operation principle of bistable state actuator and actuation mechanism thereof as follows: the Fig. 3 and 4 of take is example, if both sides permanent magnet 2 with the N utmost point in opposite directions, armature 3 is pulled on either side permanent magnet, aixs cylinder 10 under magnetic pull effect in stretching out or the stable state that bounces back.Operation reversing switch 12, in coil 4, pass into and the electric current that produces existing stable state opposite direction, armature 3 reversings, with 2 effects of both sides permanent magnet, be subject to pulling force one side to become repulsion, be subject to repulsion one side to become pulling force, make a concerted effort to make armature 3 and driving lever 8 to move round about, order about lever 7 and rotate around fulcrum, aixs cylinder 10 bounces back or stretches out under the acting in conjunction of lever 7 and spring 11; When armature 3 and 2 adhesive of opposite side permanent magnet, driving lever 8 stops mobile, aixs cylinder 10 enters new stable state, meanwhile, with travel switch 6 actions in the same way of armature 3 adhesive sides, power supply E automatically shuts down, go forward side by side into the static electricity condition that often cut-offs, actuator and actuation mechanism rely on permanent magnet magnetic pulling force to control oneself, and no longer consume electric energy, until next operation.
The present invention is not limited to above-mentioned embodiment, and persons skilled in the art, according to content disclosed by the invention, can adopt other multiple embodiment to implement the present invention.Therefore, every employing project organization of the present invention and basic ideas, do some simple designs that change or change, all within protection range of the presently claimed invention.
