Embodiment
As depicted in figs. 1 and 2, its for an embodiment rotation angle amplification device 10 assembling and split structural representation
Figure.
Rotation angle amplification device 10 includes：Transition piece 110, pressing plate 120 and swing rod 130.
Transition piece 110 include pressing board 111, the rotating part 112 on pressing board 111 and, one end is fixedly connected on pressing board
Two on 111 equidirectional extensions and between leave the tong arm 113 in gap.In the present embodiment, the fixing end point of two tong arms 113
Not Wei Yu rotating part 112 both sides.
Pressing plate 120 includes body 121 and first rotation section 122 of two diameter parallels and second turn on body 121
Dynamic portion 123.First rotation section 122 and the diameter parallel of the second rotation section 123.
Swing rod 130 includes what is be sequentially connected：Revolving part 131, moving part 132 and swing component 133.In the present embodiment, swing
The section of part 133 is circle, and its shape can be spheroidal or cylinder.
Transition piece 110 is coordinated by the first rotation section 122 on its rotating part 112 and pressing plate 120, and rotation is fixed.This reality
Applying example is：The cooperation of rotary shaft and rotation slot.
Swing rod 130 is coordinated by the second rotation section 123 on its revolving part 131 and pressing plate 120, and rotation is abutted.This implementation
Example be：Cambered surface groove and the raised cooperation of cambered surface.
The swing component 133 of swing rod 130 is located between two tong arms 113 of transition piece 110, and is abutted with two tong arms 113.
It should be noted that abutting herein is perfect condition, actual conditions are that the gap allowed between tong arm 113 and swing component 133 is smaller
Better.
The axis of the first rotation section 122 on pressing plate 120 is more than the second rotation section to the distance at the center of swing component 133

Please refer to Fig. 3, it is the rotation angle amplification device 10 shown in Fig. 2 from the axis of the first rotation section 122, the
The axis of two rotation sections 123 and the center of swing component 133 in one plane in the state of, transition piece 110 rotates to an angle
View afterwards.
Wherein, axle center a is the axle center of the first rotation section 122, and axle center b is the axle center of the second rotation section 123, and center c is pendulum
The center of moving part 133, θ1The angle rotated for transition piece 110, θ2The angle rotated for swing component 133.Due to the first rotation section
122 axis to the center of swing component 133 distance be more than the second rotation section 123 axis to the center of swing component 133 away from
From so θ2It is naturally larger than θ1.When the first rotation section 122 axis to the center of swing component 133 distance be equal to the second rotation section
When 123 axis is to two times of the distance at the center of swing component 133, θ2Equal to θ1Twice.That is, if transition piece 110 rotates 3 °,
Swing component 133 can then rotate 6 °.So just realize the amplification of the anglec of rotation.Anglec of rotation enlargement ratio can be by changing first
The axis of rotation section 122 is to the distance at the center of swing component 133 and the axis of the second rotation section 123 to the center of swing component 133
The ratio of distance realize.

Slided on seesaw component 250, after pellet 242 slides past the contact point of seesaw component 250 and support copper sheet 260, spring
241 elongations, pellet 242 withstands seesaw component 250 and is allowed to make electrical contact with the terminal assemblies 270 with contact, or separates.Seesaw
After component 250 makes electrical contact with the terminal assemblies 270 with contact, via support copper sheet 260, two (a pair) terminal assemblies 270
Connect, it is on the contrary then disconnect.
Realized with the low grade of pressing plate 220 when the angle rotatable of transition piece 210 can be rotated by transition piece 210.
Due to swing rod 230 the anglec of rotation be more than transition piece 210 the anglec of rotation (principle the foregoing anglec of rotation amplify fill
Interpreted in putting, it is not repeated herein), for relatively conventional switch, after the anglec of rotation of transition piece 210 is reduced, pendulum
The rotation of bar 230 is still larger so that slide stroke of the pellet 242 on seesaw component 250 remains to disclosure satisfy that requirement.
The above-mentioned structure of switch 20 can keep the angle of swing rod 230 basic while 210 anglec of rotation of transition piece is reduced
It is constant, even more greatly, and seesaw structure can be applicable, it is more stable with respect to swing rod structure.
