Specific embodiment

The various embodiments of the disclosure will only be described in detail by exemplary approach now.

With reference to Fig. 1, it illustrates the switches according to the first embodiment of the disclosure.The switch can be used for various controls In the switching device of connecting and disconnecting of the circuit, such as at least one switch can be mounted in switch panel to constitute and be adapted to mount to Switching device on wall, to control the switch operation of such as electric light.

As shown in Figure 1, the switch includes the shell being made of upper casing 91 and lower casing 92.Button 1 is accommodated in the shell, is driven Moving part 2, can about first axle swing swing component 3, elastic element 4, the first moving contact 81 and second on swing component 3 Moving contact 82, moving contact connecting terminal 83, the first static contact 51 and the second static contact 52.As in Figure 2-4, have on button 1 There is button contact surface 11, and there is actuator contact surface 21 on actuator 2.Fixing groove 23 is additionally provided on actuator, with It is pivotally mounted one end of elastic element 4.When elastic element 4 is connected between actuator 2 and swing component 3, elastic element 4 The actuator contact surface 21 for forcing actuator 2 is resisted against on the button contact surface 11 of button 1 by elastic-restoring force.Elastic element 4 It can be pressure spring, torsional spring or other forms, as long as it can apply elastic-restoring force to actuator 2 and swing component 3 respectively.

In the embodiment shown in Fig. 2-3, button contact surface 11 is convex globoidal, and actuator contact surface 21 is plane, And there is tooth on button contact surface 11 and actuator contact surface 21.In this way, being connect when actuator contact surface 21 is resisted against button When in contacting surface 11, tooth on actuator contact surface 21 by with the tooth engagement on button contact surface 11.Such structure will so that When actuator contact surface 21 moves (not sliding relative to each other) along the button contact surface 11 " rolling " of convex globoidal shape, drive Moving part 2 can be swung relative to button 1.During the swing, on actuator contact surface 21 and 11 the two of button contact surface Between junction will change, especially when actuator 2 swings to left and right two extreme positions, actuator contact Face 21 will engage respectively at the both ends of its lie farthest away with two ends on button contact surface 11.In two pendulum of actuator The variation of the position at dynamic extreme position junction is advantageous the reset of actuator 2, this will be described in detail below.

Intermeshing tooth on actuator contact surface 21 and button contact surface 11 ensure that actuator during the swing Contact surface 21 is only capable of engaging along button contact surface 11 " rolling " and cannot generating sliding between, this is for making actuator 2 Each swing reset be important.Opposite sliding occurs between actuator contact surface 21 and button contact surface 11 in order to prevent, It can also be not provided with tooth, but make that there is enough coefficient of frictions between actuator contact surface 21 and button contact surface 11 and make Actuator 2 is only capable of opposite roll under the action of the restoring force of elastic element 4 between actuator contact surface 21 and button contact surface 11 It moves without sliding.This can be by increasing the surface roughness of actuator contact surface 21 and button contact surface 11 or in the two Apply nonskid coating and realizes.

Driving when in order to make actuator 2 make actuator 2 swing to left and right two extreme positions relative to the swing of button 1 Part contact surface 21 is different from the joint position on button contact surface 11, can also be by actuator contact surface 21 and button contact surface 11 are set as other shapes.For example, convex globoidal can be set by actuator contact surface 21 and set button contact surface 11 to Plane, or actuator contact surface 21 and button contact surface 11 are both configured to convex globoidal.

It can also set button contact surface 11 to abnormal curved surface, and actuator contact surface 21 is set as at least having The part complementary with the shape of two ends of the abnormal curved surface of button contact surface 11.For example, as shown in figure 5, button contact surface 11 is recessed in inward at both ends and middle section is raised, then actuator contact surface 21 at least has and the part to concave at this both ends The part of the convex of shape complementation, thus the rolling to pass through with actuator contact surface 21 along button contact surface 11 It is dynamic, actuator contact surface 21 at least properly cooperate in the extreme position of the left and right of swing two and button contact surface 11 so that Actuator 2 can be in the extreme position that the two swing successfully around different engagement spot wobbles.Of course it is advantageous that driving The middle section of part contact surface 21 is also complementary with the middle section of button contact surface 11, in this way when actuator 2 swings to interposition When setting, the middle section of actuator contact surface 21 is also matched with the middle section of button contact surface 11, to be conducive to actuator 2 Smoothly the other end is swung to from one end.

As shown in fig. 6, button contact surface 11 may be the trapezoidal of indent and have fillet in trapezoidal upper apex, And actuator contact surface 21 then at least has the straight flange and fillet that the trapezoidal shape of bevel edge and fillet with the indent is complementary. This equally may be implemented actuator 2 and successfully swings to the other end from one end.

Fig. 7 shows the swing component 3 in Fig. 1.The swing component 3 includes swinging piece 34 and actuating arm 35.First moving contact 81 It is located on opposite two side for swinging piece 34 with the second moving contact 82.The bottom end for swinging piece 34 is swing support portion 31, Swinging support is on the conductive seat 84 for being electrically connected to moving contact connecting terminal 83, so that swing component 3 can be about first axle string pendulum It is dynamic.Swinging also has protrusion 36 on piece 34, in order to be pivotally supported elastic element 4.Actuating arm 35 it is longitudinally perpendicular in pendulum Movable plate 34, the first contact surface 32 and the second contact surface 33 extend on actuating arm 35 and are symmetrically distributed in about the first axle First axle it is not ipsilateral.34 part of piece that at least swings of swing component 3 is conductive material, thus via piece 34 and conduction is swung The first moving contact 81 swung on piece 34 and the second moving contact 82 are electrically connected to moving contact connecting terminal 83 by seat 84.

In one embodiment, the first contact surface 32 and the second contact surface 33 are remote from one end close each other to it The extending direction at end tilts an angle A towards the side of first axle about the direction perpendicular to the main surface for swinging piece 34, makes The first contact surface 32 and the second contact surface 33 extending direction be no longer normal to swing piece 34 main surface it is (clear in fig. 8 Ground is shown).This is particularly advantageous for reducing the stroke of button 1 and actuator 2 in the operating process of switch, this will be Explained later in detail.Advantageously, the inclined angle is between 0 degree to 20 degree.The inclined angle is, for example, 5 degree.

Fig. 3 is returned to, there is actuating arm 24 on actuator 2, drive surface 22 is formed in the end of actuating arm, to be used for and pendulum The first contact surface 32 and the contact of the second contact surface 33 on moving part 3 is to drive swing component 3 to swing.In one embodiment, Drive surface 22 is formed in the groove of 2 one end of actuator, in order to drive surface 22 drive swing component 3 swing during always It is kept in contact with the first contact surface 32 or the second contact surface 33 without being detached from from it.

In one embodiment, the drive surface 22 on actuator 2 is non-planar, especially about the end of actuating arm 24 Convex surface so that pressing the first contact surface 32 of swing component 3 in drive surface 22 or during the second contact surface 33, drive surface The change in location contacted with first contact surface 32 or the second contact surface 33 on 22.This is in the operating process of switch The stroke for reducing button 1 and actuator 2 is particularly advantageous, this will be described in detail below.

As shown in Fig. 1 and Fig. 9, it is equipped with locating part 6 in the shell.Locating part 6 is located at the two sides of actuator 2 to limit driving Two swing extreme positions of part 2.Additionally or alternatively, as shown in Figure 2 and Figure 9, limit can be equipped on button 1 Face 12, confined planes 12 can also limit the swing extreme position of actuator 2.

Button 1, actuator 2, elastic element 4 and the swing component 3 of switch are assembled together according to state shown in Fig. 9, So that in the nature that button 1 is not pressed, 4 one end of elastic element make it in locating part 6 against actuator 2 and/or It is maintained at the swing extreme position to side (in Fig. 9 for the right) under the constraint of confined planes 12, and the other end of elastic element 4 Swing component 3 is forced to be maintained at the swing extreme position (i.e. first position) to the other side opposite with the swaying direction of actuator 2, So that the first moving contact 81 on the side left side of swing component 3 (in Fig. 9 be) of swing component 3 is in swing position to the left It is contacted with the first static contact 51 (being not shown in Fig. 9) for being located at 3 left side of swing component, and the other side of swing component 3 (is in Fig. 9 The right side of swing component 3) on the second moving contact 82 be also at swing position to the left and be located at 3 right side of swing component it is second quiet Contact 52 (being not shown in Fig. 9) disconnects.Therefore, in this state, the swing component 3 of the switch will be with swing component 3 and conductive seat 84 Associated moving contact connecting terminal 83 and the circuit (i.e. between the associated first static contact connecting terminal of the first static contact 51 One circuit) conducting, while will be closed with swing component 3 and the associated moving contact connecting terminal 83 of conductive seat 84 and with the second static contact 52 Circuit (i.e. second circuit) between second static contact connecting terminal of connection disconnects.At this point, the drive surface 22 of actuator 2 is apart from pendulum Second contact surface 33 on the right side of moving part 3 is not contacted or is just contacted without applying to the second contact surface 33 and swing component 3 Active force.

In the situation of figure 9, since actuator 2 is located at the swing position of its rightmost side, the actuator on actuator 2 Contact surface 21 engages at the point of its rightmost side with the button contact surface 11 of button 1.At this point, the company of elastic element 4 and actuator 2 Contact is located at the company of the tie point of elastic element 4 and swing component 3 and the junction of actuator contact surface 21 and button contact surface 11 The right side of line, and elastic element 4 due to be pivotably attached between actuator 2 and swing component 3 and always along elastic element 4 with The direction of line between the tie point and elastic element 4 and the tie point of actuator 2 of swing component 3 applies to actuator 2 replys Power, therefore, elastic element 4, which acts on the restoring force on actuator 2, to be applied to actuator 2 about the actuator for being located at the rightmost side The anticlockwise torque at the junction of contact surface 21 and button contact surface 11, actuator 2 is resisted against limit by the torque as a result, Actuator 2 is made to be maintained at the swing extreme position on position part 6 and/or confined planes 12.

As shown in Figure 10, when pressing lower button 1, actuator 2 will move down under the action of button 1.Due to by bullet Property element 4 apply anti-clockwise torque and locating part 6 and/or confined planes 12 constraint, actuator 2 is during moving down It will not be swung relative to button 1, then actuator contact surface 21 and the position at the junction of button contact surface 11 will not become Change, and is still located on the right end of actuator contact surface 21 and button contact surface 11.During the pressing, when actuator 2 Drive surface 22, which touches to continue after the second contact surface 33 of swing component 3 to press the second contact surface 33, makes swing component 3 towards right side It swings.Since actuator 2 is not swung during the pressing and swing component 3 is then swung to the right during the pressing, Actuator 2 contacted with swing component 3 after pressing during, the relative attitude between actuator 2 and swing component 3 will become Change, i.e., the position that the drive surface 22 of the driven member 2 on the second contact surface 33 of swing component 3 presses moves closer to the first contact surface 32 and second contact surface 33 one end adjacent to each other, i.e. the center close to swing component 3.

As shown in figure 11, when continuing push button 1, swing component 3 will swing by its middle position relative to shell And it swings to and the swing extreme position (i.e. the second position) on side opposite before (right side in Figure 11).In the process, Once the tie point that swing component 3 swings to swing component 3 and elastic element 4 is located at the right side of elastic element 4 with the tie point of actuator 2 When side, the restoring force of elastic element 4 will drive the acceleration of swing component 3 to swing to right side to the right and swing extreme position.At this point, swing component The second moving contact 82 on 3 right sides contacts with second static contact 52 on 3 right side of swing component and second circuit is connected, and puts simultaneously First static contact 51 of the first moving contact 81 and 3 left side of swing component on 3 left side of moving part disconnects and disconnects the first circuit, from And realize the switch to the on-off handover operation of the first circuit and second circuit.

During above-mentioned push button 1, with the swing of swing component 3, actuator 2 is not swung, so that the second contact The position contacted with drive surface 22 on face 33 gradually changes, and the pendulum of power and swing component 3 that actuator 2 applies swing component 3 Torque arm length between shaft line (i.e. first axle) remains unchanged.In this way, during the whole process of push button 1, driving Part 2, which can be remained, swings same angle with same per stroke driving swing component 3, without with swing component 3 Swing and be gradually distance from the axis of oscillation of swing component 3 so as to cause need with bigger per stroke come drive swing component 3 swing Same angle.1 switching circuit of button that the driving mechanism that the actuator 2 and swing component 3 form as a result, shortens the switch is grasped Pressing stroke needed for making, facilitates the operation of user.

It is closed in the extending direction of the first contact surface 32 and the second contact surface 33 from one end close each other to its distal end In the case where tilting an angle A towards the side of first axle perpendicular to the direction for the main surface for swinging piece 34, with swing The drive surface 22 of the swing of part 3, actuator 2 can be during the second contact surface 33 relative to swing component 3 be mobile faster It is fastly mobile to the center of swing component 3.This makes actuator 2 press down on the mobile relatively smaller stroke of swing component 3 Swing component 3 is set to swing same angle and the operating position of the on-off that reaches switching circuit.Therefore, which further contracts Pressing stroke needed for 1 switching circuit of the button operation of the short switch, facilitates the operation of user.

In the case where the drive surface 22 of actuator 2 is the convex surface of the non-planar end especially about actuating arm 24, With the swing of swing component 3, during the drive surface 22 of actuator 2 is mobile relative to the second contact surface 33 of swing component 3, Side (the drive surface in Figure 10 at the center closer to swing component 3 positioned at drive surface 22 of the second contact surface 33 of swing component 3 22 left side) part will be contacted earlier with the part of the side at the center closer to swing component 3 of drive surface 22.This is into one Step so that actuator 2 press down on the mobile relatively smaller stroke of swing component 3 can just make swing component 3 swing same angle and Reach the operating position of the on-off of switching circuit.Therefore, which further shortens the button 1 of the switch Pressing stroke needed for switching circuit operation, facilitates the operation of user.

When from state release button 1 in Figure 11, since swing component 3 has swung to the swing limit on right side at this time Tie point between position, i.e. elastic element 4 and swing component 3 is deflected to the other side of swing component 3 (being right side in Figure 11), So that the tie point of elastic element 4 and actuator 2 becomes tie point and actuator contact surface in elastic element 4 and swing component 3 21 with the left side of the line at the junction of button contact surface 11, therefore, elastic element 4 acts on the restoring force on actuator 2 will Apply the clockwise direction at the junction about the actuator contact surface 21 and button contact surface 11 for being located at the rightmost side to actuator 2 Torque.The clockwise torque will drive the actuator contact surface 21 of actuator 2 along the button contact surface 11 of button 1 " rolling " and make the side oscillation to the left of actuator 2, as shown in figure 12.During " rolling ", actuator contact surface 21 and button Junction between contact surface 11 will be gradually moved to the left.

Even if when actuator 2 swings to the middle position as shown in Figure 12 about shell, i.e. actuator contact surface 21 With the tie point of the junction of button contact surface 11 and actuator 2 and elastic element 4 all in the middle position about shell When, due to swing component 3 and elastic element 4 tie point always because swing component 3 is maintained at swing extreme position to the right and position In right side, therefore the tie point of elastic element 4 and actuator 2 is still within tie point and the driving of elastic element 4 and swing component 3 The left side of the line at the junction of part contact surface 21 and button contact surface 11.Therefore, elastic element 4 acts on actuator 2 Restoring force will apply the junction about centrally located actuator contact surface 21 and button contact surface 11 to actuator 2 Clockwise torque, and actuator 2 is made to continue to swing to the left and by axis of oscillation (the i.e. first axle of swing component 2 Line), make until on the locating part 6 and/or confined planes 12 that actuator 2 abuts to the left side of the axis of oscillation positioned at swing component 2 It obtains actuator 2 and is maintained at the swing extreme position, as shown in figure 13.At this point, actuator contact surface 21 and button contact surface 11 Junction has been moved into the leftmost side of actuator contact surface 21 and button contact surface 11.

In the swing process of the above actuator 2, since button 1 has been released, the restoring force of elastic element 4 drives in driving While the swing of moving part 2, also driving actuator 2 and button 1 move up and separate swing component 3 together.Therefore, in actuator In 2 swing process, actuator 2 no longer contacts and presses swing component 3.That is, being driven in the swing process of actuator 2 The movement of moving part 2 not will receive the influence of swing component 3, while swing component 3 also will be in the effect of the elastic-restoring force of elastic element 4 Under remain at limit swing position to the right and keep the operation shape of the connection of the disconnection and second circuit to the first circuit State.And actuator 2 will also be kept under the action of the restoring force of the constraint of locating part 6 and/or confined planes 12 and elastic element 4 Swing extreme position in the leftmost side.The homing action of button 1 is completed as a result, and actuator 2 is also button next time 1 pushing operation is got ready.

When pressing lower button 1 again, actuator 2 will be driven by button 1 and move down and contact and press 3 left side of swing component First contact surface 32 of side and swing swing component 3 to the left, while actuator 2 keep relative to button 1 swing so that swing First moving contact 81 in 3 left side of part is contacted again with the first static contact 51, and second moving contact 82 and second on 3 right side of swing component Static contact 52 is again off, and thus switch is again switched on the first circuit and disconnects second circuit, to realize switch to the first electricity The on-off handover operation again on road and second circuit.During the pressing, the drive surface 22 of actuator 2 also will be relative to swing First contact surface 32 of part 3 is mobile and moves closer to the center of swing component 3, and also second will be driven to contact 33 with drive surface 22 When it is the same, realize shorten actuator 2 stroke effect.

When release button 1 again, actuator 2 will be according to the mistake similar with the process described above with respect to Figure 11-Figure 13 Cheng Zaici swings to the swing extreme position of the rightmost side, while actuator contact surface 21 and the junction of button contact surface 11 also will The right end of actuator contact surface 21 and button contact surface 11 is changed to, again for the driving of actuator 2 next time swing The movement of part 3 and the swing reset of actuator 2 are ready.

In the embodiment of switch described above, do not swung during driving swing component 3 due to actuator 2 or Rotation, the distance between actuator 2 and the axis of oscillation of swing component 3 remain constant, and therefore, actuator 2 can be with constant Per stroke driving swing component 3 swing same angle so that the stroke (and stroke of button 1) of actuator 2 can With smaller.Therefore, user can more easily operation button 1 with realize switch reliable handover operation.Moreover, because actuator 2 driving swing components 3 swing the distance between the axis of oscillation that determinant in place is actuator 2 Yu swing component 3, therefore, The switch can be made to obtain desired drive and being simply to set the distance between the axis of oscillation of actuator 2 and swing component 3 The stroke of moving part 2 stroke and button 1.For example, the row of actuator 2 and button 1 can be made by being arranged the distance enough to small Journey becomes smaller.

In the embodiment of switch described above, the direction for the power that actuator 2 acts on swing component 3 with by pressing The direction of the power of button 1 is essentially identical.Therefore, the major part of the power of user's push button 1 can be converted into the drive of actuator 2 Movable pendulum moving part 3 is acted to switch the effective force of the position of moving contact.Therefore, the high conversion efficiency of the power in the switch, to drop The requirement of the low power to user's push button 1.
