In embodiment, draft arm 104 can also be set and be hinged to actuating arm 103, it is small to allow draft arm 104 to make during translational motion
Angular turn.The upper end of driving lever 105 is hinged to the end of draft arm 104.In the hinged place, draft arm 104, which can have, to be used for
The retainer that driving lever 105 rotates is limited, to limit the maximum rotation angle of driving lever 105.Rotating member 101 has turntable 101
Form is provided at least one protruded stigma 106.It can be resisted against by the driving lever 105 of limitation rotation prominent on rotating member 101
The right side of column 106, and drive rotating member 101 to rotate by stirring protruded stigma 106.As shown in Figure 1B, when driving lever 105
When upper end is against this retainer, the angle between draft arm 104 is defined as substantially 90 degree.In other embodiments,
Other maximum rotation angles are also feasible, are greater than 90 degree or are less than 90 degree, as long as by 105 energy of driving lever of limitation rotation
Enough driving rotating members 101 rotate.In addition, the hinged place of driving lever 105 and draft arm 104 is additionally provided with torsional spring, which is dialling
Apply spring bias between bar 105 and draft arm 104, to promote driving lever 105 to be at the position of maximum rotation angle.
As shown, in double power supply automatic transfer switch, two groups of identical electromagnetic drive mechanisms, the two mirror can be set
The upper side and lower side as being symmetrically disposed in rotating member 101.The driving lever 105 of the electromagnetic drive mechanism 101 of upside can stir rotation
Part 101 rotates counterclockwise, and the driving lever of the second electromagnetic drive mechanism of downside can stir rotating member 101 and rotate clockwise.Rotating member
There are four protruded stigmas for setting on 101, are symmetrical arranged about shaft, and each two protruded stigma is used for same group of electromagnetic drive mechanism,
For example, the first protruded stigma 106A and the second protruded stigma 106B in figure are used for the driving lever 105 of the first electromagnetic drive mechanism 101.The two
The angle of protruded stigma can be 60 degree, can be other angles in other embodiments, to realize desired rotational angle.Below with
Illustrate operation principle for the electromagnetic drive mechanism 100 of upside, it should be appreciated that these explanations are equally applicable to another electricity of downside
Magnetic driving mechanism.
As shown in Figure 1A, for electromagnet 102 without being energized, actuating arm 103 is simultaneously in the right lateral position far from electromagnet 102
It sets.At this point, the maximum distance of the shaft due to protruded stigma 106A and 106B apart from rotating member 101 is less than draft arm 104 and driving lever 105
Therefore minimum range apart from shaft when rotating member 101 is driven and rotated clockwise by another driving mechanism of downside, is driven
Swing arm 104 and driving lever 105 will not be interfered with protruded stigma 106A or 106B, to allow another driving mechanism to work independently, instead
It is as the same.
When electromagnet 102 must be electric, actuating arm 103 is moved to from right positions shown in figure 1A shown in Figure 1B by driving
Close electromagnet leftward position.Meanwhile actuating arm 103 drives driving lever 105 to translate via the draft arm 104 of linkage.When dial
When edge is against the first neighbouring protruded stigma 106A to the left, driving lever 105 keeps being in maximum rotation angle position bar 105,
And it stirs the first protruded stigma 106A to move along arc track, so that rotating member 101 turns over first angle.During this period, protruded stigma
106A slides along the left side edge of driving lever 105, without being interfered with draft arm 104.With the rotation of rotating member 101,
The movable contact of switch switches to double point positions from the first position of source.
When 102 dead electricity of electromagnet, actuating arm 103 is under the action of resetting spring to right translation.With actuating arm 103
Mobile, the right side edge of driving lever 105 contacts the left side of the second protruded stigma 106B.Since the rotation stop torque of rotating member 101 is more than driving lever
105 rotation stop torque, therefore, rotating member 101 will not rotate clockwise, also, the second protruded stigma 106B can push driving lever to
Left side is swung so that the angle between driving lever 105 and draft arm 104 is gradually reduced, meanwhile, the right side edge of driving lever 105 close to
The periphery of second protruded stigma 106B is slided, until driving lever 105 is whole to cross the second protruded stigma 106B, as shown in Figure 1 C.Once crossing
Second protruded stigma 106B, under the bias effect of torsional spring, driving lever 105 springs back to the initial position perpendicular to draft arm 104.With drive
Swing arm 103 continues to move right, and driving lever 105 finally returns back to its initial position, as shown in figure iD.The phase is acted in this reply
Between, rotating member 101 and its equal remains stationary of protruded stigma, moving contact are maintained at double point positions.
When electromagnet 102 again it is electric when, actuating arm 103 by driving and another ground is moved to the left so that driving lever
105 against the right side of the second protruded stigma 106B, as referring to figure 1E.With the pulling function of actuating arm 103, driving lever 105 stirs second
Protruded stigma 106B rotations so that rotating member 101 turns over second angle counterclockwise, as shown in fig. 1F.At this point, moving contact divides position from double
Switch to second source position.In drive actions twice, the stroke of actuating arm 103 is identical, the angle of rotation twice of rotating member 101
Degree is also identical.
When dead electricity, actuating arm 103 can drive driving lever 105 directly to return back to it and be initially position electromagnet 102 again.This
When, another electromagnetic drive mechanism work of downside can be operated.Similar to the above processly, another electromagnetic drive mechanism can drive
Rotating member rotates clockwise, and to drive moving contact to switch to double point positions from second source position, or switches from double points of positions
To the first position of source.
By the way that the excitation sequence of the electromagnet 102 of upside and another electromagnet of downside is arranged, may be implemented any desired
The sequence of switches.It should be noted that two electromagnet cannot be encouraged simultaneously, occur to avoid the movement of two sets of electromagnetic drive mechanisms
Interfere and damages parts.
Second embodiment
Fig. 2A to Fig. 2 F shows the schematic diagram of the electromagnetic drive mechanism 200 of second embodiment.Electromagnetic drive mechanism 200 wraps
Include the hook arm 205 for being hinged to actuating arm 203.The end of hook arm 205 has towards 201 hook portion 205A outstanding of rotating member.Rotation
Part 201 is set as the form of ratchet, at least one ratchet 206 that periphery is provided with.The right side of each ratchet 206 is stop

As shown, in double power supply automatic transfer switch, two groups of identical electromagnetic drive mechanisms, the two mirror can be set
The upper side and lower side as being symmetrically disposed in ratchet 201.The hook arm 205 of upside can pull ratchet 201 to rotate counterclockwise, downside
Another hook arm can pull the ratchet to rotate clockwise.Ratchet there are four being arranged on ratchet 201, about in ratchet
The heart is symmetrical arranged, and each two ratchet is used for the same hook arm, is conducive to the first ratchet 206A and the second ratchet 206B of upside
It is engaged for the hook arm 205 with upside.It can be 30 degree the angle between two ratchets 206A and 206B, in other embodiments
In can be other angles, to realize desired rotational angle.Illustrate work by taking the electromagnetic drive mechanism of upside 200 as an example below
Make principle, it should be appreciated that these explanations are equally applicable to another electromagnetic drive mechanism of downside.
As shown in Figure 2 A, electromagnet 202 is not driven, and actuating arm 203 is simultaneously in the right lateral position far from electromagnet 202
It sets, hook arm 205 is between the first ratchet 206A and the second ratchet 206B.When electromagnet 202 must be electric, actuating arm 203 is driven
It is dynamic so that the hook portion 205A of hook arm 205 is moved to the right side motion-stopping surface against the first ratchet 206A, as shown in Figure 2 B.Continue to drive
Dynamic actuating arm 203 is to left, and hook arm 205 can pull ratchet 201 to turn over an angle, such as 30 degree, as shown in Figure 2 C.At this point,
Movable contact switches to double point positions from the first position of source.
During this period, actuating arm 203 drives a blocking lever 207 to rotate, to push the hook arm of downside far from ratchet
201.It is pivoted as shown, blocking lever 207 can surround its shaft 207A.The upper end of blocking lever 207 has the section projected upwards
207B, this protrusion section 207B can unilaterally be attached to the raised 203A being arranged on actuating arm 203；Latch lever 207
Lower end can unilaterally be attached to another protrusion being arranged in another hook arm of downside.With reference to figure 2A and Fig. 2 B, when actuating arm 203
When being moved to the left, the raised 203A of actuating arm 203 is moved along prominent section 207B, to apply in the upper end of blocking lever 207
One torque so that latch lever 207 turns over an angle counterclockwise, and at the same time, the lower end of blocking lever 207 deflects down and is pressed against
Another protrusion in another hook arm, to drive another hook arm of downside to deflect down.As a result, the hook portion of another hook arm is de-
From corresponding ratchet.As a result, during subsequent drive arm 205 pulls ratchet 201 to rotate, ratchet 201 will not be by downside
Another hook arm interference, as shown in Figure 2 C.Similarly, another electromagnetic drive mechanism of downside also has similar second chain
Bar may insure that the operation of the electromagnetic drive mechanism of downside will not be interfered by the electromagnetic drive mechanism of upside.On as a result,
Lower two electromagnetic drive mechanisms can act independently of one another, and will not interfere with each other.
When 202 dead electricity of electromagnet, actuating arm 203 under the action of resetting spring to right translation, and drive hook arm 205 to
It moves right.With the movement of actuating arm 203, hook arm 205 is deflected outward in the outer peripheral edge of ratchet 201 under, meanwhile, hook arm
205 hook portion 205A is slided along the left side slide surface of the second ratchet 206B, until crossing the second ratchet 206B and falling into its right side
