Embodiment
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As shown in Fig. 1 ~ Fig. 2: as described in the switching mechanism of automatic transfer switching electric appliance comprise fixed core 1, cushion pad 2, coil 3, dynamic 4, first axle 5, first connecting rod 6, rotating shaft 7, second axle 8, spring 9, housing 10, second connecting rod 11, third connecting rod 12, main power source bus 13, stand-by power supply bus 14, load bus 15, rocking arm 16, double leval jib 17, the 5th connecting rod 18, moving contact 19, arc-extinguish chamber 20 unshakable in one's determination etc.
As shown in Figure 1, the utility model comprises housing 10, symmetrical installation coil 3, dynamic iron core 4 and fixed core 1 in housing 10, and it is inner that dynamic iron core 4 and fixed core 1 are positioned at coil 3, arranges cushion pad 2 between dynamic iron core 4 and fixed core 1; Dynamic unshakable in one's determination 4 of described housing 10 left and right sides is connected by second connecting rod 11, second connecting rod 11 is rotationally connected with one end of first connecting rod 6 and one end of third connecting rod 12 respectively by the first axle 5, the other end of first connecting rod 6 is connected with rotating shaft 7, rotating shaft 7 is connected with contact system, the other end of third connecting rod 12 is rotationally connected with housing 10 by the second axle 8, between housing 10 and the second axle 8, spring 9 is set, spring 9 can give linkage confining force by the second axle 8, ensures that linkage action does not rebound after putting in place.Operationally, when the left side coil 3 electric time, dynamic unshakable in one's determination 4 can to fixed core 1 toward move left, and dynamic unshakable in one's determination 4 when being expressed to cushion pad 2, coil 3 power-off; When dynamic iron core 4 is moved to the left, the first axle 5 also can and then be moved to the left, thus drives first connecting rod 6 to turn left, and first connecting rod 6 drives rotating shaft 7 to rotate clockwise; After first axle 5, first connecting rod 6, rotating shaft 7 rotate in place, spring 9 can give their confining forces by the second axle 8, ensures that mechanism action does not rebound after putting in place.On the contrary, when the right coil 3 electric time, dynamic unshakable in one's determination 4 can to fixed core 1 toward move right, and dynamic unshakable in one's determination 4 when being expressed to cushion pad 2, coil 3 power-off; When dynamic iron core 4 moves right, the first axle 5 also can and then move right, thus drives first connecting rod 6 to turn right, and first connecting rod 6 drives rotating shaft 7 to rotate counterclockwise; After first axle 5, first connecting rod 6, rotating shaft 7 rotate in place, spring 9 can give their confining forces by the second axle 8, ensures that mechanism action does not rebound after putting in place.This completes an actuation cycle.When rotating shaft 7 is rotated, the action of contact system can be driven, thus complete load supplying power supply and be transformed into B-source from a-power supply or B-source is transformed into a-power supply.
As shown in Figure 2, described contact system comprises the main power source bus 13 be arranged on the left of housing 10, installs stand-by power supply bus 14 on the right side of housing 10, installation load bus 15 below stand-by power supply bus 14; In the middle of described housing 10, install rocking arm 16; both sides of rocking arm 16 bottom are rotationally connected respectively by bearing pin and double leval jib 17 and the 5th connecting rod 18; double leval jib 17 and the 5th connecting rod 18 are rotationally connected with the moving contact 19 of the left and right sides respectively; lower end and the housing 10 of moving contact 19 are rotationally connected, corresponding main power source bus 13 and stand-by power supply bus 14 are distinguished in the upper end of moving contact 19.The lower end of described moving contact 19 is respectively in circular arc-shaped end, and two arc surfaces that this circular arc-shaped end and load bus 15 are formed match.During work, when rocking arm 16 turns left, the upper end of the moving contact 19 on the left side contacts with main power source bus 13, and lower end arc surface rotates in the arc surface of load bus 15, and the moving contact 19 on the right is away from stand-by power supply bus 14; Contrary to rocking arm 16 turns right, the upper end of the moving contact 19 on the right contacts with stand-by power supply bus 14, and lower end arc surface rotates in the arc surface of load bus 15, and the moving contact 19 on the left side is away from main power source bus 13.
Outside described moving contact 19, wrap up arc-extinguish chamber 20, form independently arc control device.
The switching mechanism of automatic transfer switching electric appliance described in the utility model is that the power supply of powering load and fast speed (within 50ms) are transformed into B road from A road, can ensure the continuity of the power supply of important load like this.What this mechanism adopted is symmetrical general layout, and respectively there are a coil, fixed core, dynamic unshakable in one's determination a, cushion pad in left and right, and middle connecting rod, rotating shaft pivot pin link together the dynamic iron core on both sides, the spring of bottom to mechanism with confining force.This mechanism owing to being symmetrical design, so most of parts can be general; What this mechanism adopted is the mode of twin coil in the independent adhesive in mechanism both sides, controls dynamic unshakable in one's determination side-to-side movement, thus mechanism " dead-centre position " that produce this can substantially neglect, and coil is all instantaneous work, as long as iron core moves into place, coil auto-breaking, so power consumption is very little; Between sound iron core, rubber buffer is installed, has alleviated vibrations during action unshakable in one's determination greatly.
