Embodiment
As depicted in figs. 1 and 2, it is assembling and the fractionation structural representation of the anglec of rotation amplifying device 10 of an embodiment.
Anglec of rotation amplifying device 10 comprises: transition piece 110, pressing plate 120 and fork 130.
Two the first rotation section 122 and the second rotation sections 123 that axis is parallel on pressing plate 120 comprises body 121 and is positioned at body 121.The first rotation section 122 is parallel with the axis of the second rotation section 123.
The swing component 133 of fork 130 between two tong arms 113 of transition piece 110, and with two tong arm 113 butts.Need to prove that butt herein is perfect condition, actual conditions are to make the gap of 133 of tong arm 113 and swing components the smaller the better.
The axis of the first rotation section 122 on the pressing plate 120 to the distance at the center of swing component 133 greater than the axis of the second rotation section 123 distance to the center of swing component 133.
In the present embodiment, the axis of the first rotation section 122 equals the second rotation section 123 to the distance at the center of swing component 133 axis is to two times of the distance at the center of swing component 133.
Please consult simultaneously Fig. 3, it is anglec of rotation amplifying device 10 shown in Figure 2 under the center state in one plane of the axis of the axis of the first rotation section 122, the second rotation section 123 and swing component 133, the view after transition piece 110 rotates to an angle.
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 the center of swing component 133, θ
1Be the angle of transition piece 110 rotations, θ
2Angle for swing component 133 rotations.Since the axis of the first rotation section 122 to the distance at the center of swing component 133 greater than the axis of the second rotation section 123 distance to the center of swing component 133, so θ
2Inevitable greater than θ
1The axis that equals the second rotation section 123 to the distance at the center of swing component 133 when the axis of the first rotation section 122 is during to two times of the distance at the center of swing component 133, θ
2Equal θ
1Twice.That is, if transition piece 110 rotates 3 °, 133 of swing components can rotate 6 °.So just realized the amplification of the anglec of rotation.Anglec of rotation enlargement ratio can be realized to the ratio of the distance at the center of swing component 133 to the distance at the center of swing component 133 and the axis of the second rotation section 123 by the axis that changes the first rotation section 122.
As shown in Figure 4 and Figure 5, it is solid and the decomposition texture schematic diagram of the switch 20 of the above-mentioned anglec of rotation amplifying device of use.
Please consult simultaneously Fig. 6, it is the enlarged drawing of transition piece 210 among Fig. 5, pressing plate 220, fork 230.
Pressing plate 220 comprises main body 221, is positioned at rotating shaft 222 and groove 223 on the main body.Rotating shaft 222 is parallel with the axis of groove 223.Main body offers through hole 224 on 221 middle parts.
Supporting copper sheet 260 is bending structure, and has elasticity.
Please consult simultaneously Fig. 7 and Fig. 8, it is respectively switch 20 shown in Figure 4 along the cross-sectional view of housing piece 234 positions and swing component 233 positions again.
The rotation slot 212 of transition piece 210 and 222 rotations of the rotating shaft on the pressing plate 220 are fixing, and two tong arms 213 of transition piece 210 pass the through hole 224 on the main body 221.
The revolving part 231 of fork 230 is globoidal structure, and with pressing plate 220 on groove 223 rotation butts.Cylindric swing component 233 between two tong arms 213 of transition piece 210, swing component 233 circular arc outer surfaces and two tong arm 213 butts.
The axis of rotating shaft 222 to swing component 233 centers the distance of (being the axis of cylindric swing component 233) greater than the axis (being the axis of the revolving part 231 of fork 230) of groove 223 distance to swing component 233 centers.
Supporting copper sheet 260 has two, and terminal assemblies 270 has two pairs, all is fixed in the back seat 280.An end that supports copper sheet 260 is connected with the terminal assemblies 270 that does not have the contact.One side middle part and the free end butt, the another side of seesaw assembly 250 and pellet 242 butts that support copper sheet 260 of seesaw assembly 250.
In the fork 230 rotary oscillation processes (be transition piece 210 be pressed process in), spring 241 compresses first, pellet 242 slides at seesaw assembly 250, after pellet 242 slides past seesaw assembly 250 and supports the contact point of copper sheet 260, spring 241 elongations, pellet 242 withstands seesaw assembly 250 and makes it to electrically contact with the terminal assemblies 270 with contact, perhaps separates.After seesaw assembly 250 electrically contacts with the terminal assemblies 270 with contact, namely be communicated with via supporting 260, two (a pair of) terminal assemblies 270 of copper sheet, otherwise then disconnect.
When the angle rotatable of transition piece 210 can rotate by transition piece 210 and the low grade of pressing plate 220 realize.
(principle is explained in aforementioned anglec of rotation amplifying device because the anglec of rotation of fork 230 is greater than the anglec of rotation of transition piece 210, no longer repeat) herein, relatively traditional switch, after the anglec of rotation of dwindling transition piece 210, the rotation of fork 230 is still larger, so that pellet 242 sliding stroke and still can meet the demands on seesaw assembly 250.
Above-mentioned switch 20 structures can keep the angle of fork 230 substantially constant when reducing transition piece 210 anglecs of rotation, even larger, and can be suitable for the seesaw structure, and swing rod structure is more stable relatively.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
