Embodiment
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
A kind of bistable-state permanent magnet mechanism as shown in Figure 1, comprises magnetic core 3, energy storage device 2, magnetic control means, stopping means 6 and actuating bar 7; Energy storage device 2 is spring; Being enclosed within on actuating bar 7 of spring symmetry; Magnetic core 3 two ends are equipped with actuating bar 7; Magnetic core 3 is arranged in magnetic control means; Magnetic control means comprises operating coil 1, permanent magnet 4 and yoke 5; In yoke 5, be provided with operating coil 1 and permanent magnet 4; Operating coil 1 is arranged on the end positions of magnetic core 3; Permanent magnet 4 is centered around around magnetic core 3; Operating coil 1 comprises the operating coil that two groups of head and the tail lead-in wires join; Magnetic core 3 is length-adjustable magnetic core, wherein magnetic core can be the iron core of scalable adjustment length, maybe can be convenient to the magnetic core of changing, by changing the length of magnetic core, realize the object of this device change stroke, stroke is larger, it is larger that magnetic core starts required magnetic field force, and producing electric current that equal magnetic force twin coil passes into simultaneously, obviously to pass into electric current than single coil little, and due to the use of energy-stored spring, it is less that magnetic core starts required magnetic field force, and the electric current that passes into that passes into coil can be less; Little owing to passing into electric current, variable thin, the number of turn of coil wire diameter can reduce, and corresponding volume can dwindle, thereby realizes the design of integrated model Miniaturizable.Actuating bar 7 leans out outside magnetic control means; Actuating bar 7 ends are provided with stopping means 6;
As shown in Figure 2, arrow represents coil-winding direction.First group of operating coil lead-out wire is defined as 1a, 1b, and second group of operating coil lead-out wire is defined as 2a, 2b, and two groups of operating coil lead-out wires are end to end;
As shown in Figure 3, in the time of sub-gate position, the spring in left side, in compressed energy-storage state, passes into forward dc electricity between 1a, 2b, and two groups of operating coils are simultaneously charged, the magnetic field superposition forming together, produce direction consistent magnetic fields power, for example magnetic fields power is to the right time, and left side spring discharges simultaneously, magnetic fields power and left side spring thrust jointly order about the attraction that magnetic core 3 overcomes permanent magnet 4 and start rapidly, to the separating brake of setting or the motion of closing position direction.In motion process, the spring on right side starts energy storage, produce damping force simultaneously, slow down the speed that moves right of magnetic core 3, i.e. the end speed of motion, magnetic core 3 moves to the position of initial combined floodgate or separating brake, the permanent-magnet attractive power that permanent magnet produces is greater than the thrust that right side spring produces, magnetic core 3 is remained on and closed a floodgate or open position, and also energy storage is complete for the spring on right side simultaneously, for action next time divide/is closed a floodgate ready.
