Specific embodiment

In order to which the technical features, objects and effects of invention are more clearly understood, the Detailed description of the invention present invention is now compareed Specific embodiment, identical label indicates identical part in the various figures.

A kind of switch operating device is disclosed in Chinese patent application CN102468077A, compact-sized and stabilization can It leans on, occupies little space.Based on the switch operating device, it is easy to manipulate switching device (such as from side the present invention provides one kind Switch in CN102468077A) to switch the operating unit of the switching device of different conditions.

As depicted in figs. 1 and 2, operating unit has a shell 16, and shell 16 has a through-hole 17, and operating shaft 11 is then It can be placed in the through-hole 17, a part of operating shaft 11 stretches to the inside of shell 16, some is protruded in shell 16 outsides are used as operation portion, consequently facilitating user carries out correspondingly rotating operation in hull outside by handle etc..

Operating shaft 11 stretches to one end inside shell 16 with an operating head 18, and operating shaft 11 can be in through-hole 17 Rotation, so that operating head 18 be driven to rotate, specifically, operating head 18 can cooperate with the handle hole 22 on switch operating device 20, That is, when operating head 18 is embedded into handle hole 22, since operating head 18 has the shape being adapted with handle hole 22, To which the rotation of operating head 18 can drive the movement of handle hole 22, so that the state of switch operating device 20 be driven to switch.

Since in switch operating device 20, from OFF state, into the handoff procedure of ON state, there are certain idle runnings, such as The not additional design of fruit, operating head 18 also will appear identical idle running, in order to avoid idle running influences the feel of operator, together When also avoid operating shaft 11 from shaking in this process, in conjunction with Fig. 3, also have in operating shaft 11 close to the side of operating head 18 One cam 15, in this way, operating shaft 11 rotation when also will drive cam 15 rotate, meanwhile, the two sides of operating shaft 18 also The elastic mechanism 123 of a pair of opposing, elastic mechanism 123 may include a sliding block 12 and the bullet that is nested in sliding block 12 One end of spring 13, elastic mechanism 123 abuts against cam 15 by sliding block 12, and certainly, elastic mechanism 123 can also have other shapes Formula, such as an outer cover are equipped with the top etc. of spring.This pair of of elastic mechanism arranges along the axisymmetrical of operating shaft 11, thus Cam 15 can be abutted against better, so that the movement of cam is steadily to carry out in elastic mechanism against lower always, made Feel when obtaining user's operation is preferable, will not be because shaking caused by the reasons such as idle running.

In addition, also having the position-limit mechanism 14 and 19 of limitation 15 motion range of cam on housing 16.As shown in figure 3, limit Position mechanism 14 and position-limit mechanism 19 are arranged along the axisymmetrical of operating shaft 11, and perpendicular to elastic mechanism 123, that is to say, that limit Position mechanism and elastic mechanism are at 90 degree of angles.In this way, operating shaft can realize the position ON and OFF in 90 degree of slewing area Switching between position, when switching device reaches OFF position or reaches the position ON, the presence of position-limit mechanism to continue by Become impossible according to former direction rotation operating shaft, and change state can only be rotated according to opposite direction, in this way, can be more easily The current accurate status of switching device is indicated to operator.

Illustrate the process of state switching in conjunction with Fig. 3 to Fig. 6.

In Fig. 3, switching device is in OFF state, and cam 15 is resisted against centre by the sliding block 12 of a pair of of elastic mechanism, and The confined planes 192 on confined planes 141 and position-limit mechanism 19 being limited in mechanism 14 limit clockwise movement tendency.

If necessary to which the state of switching device is switched to ON state manually, the operation of operating shaft 11 at this moment can be operated Portion, so that operating shaft rotates counterclockwise, cam 15 can then compress sliding block 12 and then elasticity of compression mechanism 123, so that spring-compressed Reach maximum, it is corresponding at this time as shown in figure 4, elastic mechanism is located at dead-centre position, in switch operating device 20, this When spring be also at dead-centre position, that is to say, that now with the storage power of two dead-centre positions of operating unit and switch operating device.

In Fig. 5, operating shaft 11 continues to rotate counterclockwise, and the sliding block 12 of elastic mechanism then continues to abut against cam 15, from And even if there is idle running appearance in switch operating device 20, operator, which will not feel, to be significantly present of, moreover, by dead The storage power of point position, operating shaft 11 more can be continued to rotate easily until ON state shown in fig. 6, at this point, sliding block 12 according to Cam 15 so is abutted against, moreover, confined planes 191 of the cam 15 also by the confined planes 142 of position-limit mechanism 14 and position-limit mechanism 19 Blocking, to will not further rotate counterclockwise.

The present invention also provides a kind of switching device groups, as shown in fig. 7, the switching device group includes a plurality of switching dresses It sets, 3 switching devices 31,32 and 33 is shown in FIG. 7, in addition, further including a switch operating mechanism 20 and an operation Unit 10, switch operating mechanism 20 is connect with operating unit 10, in this way, there is two manipulation directions of a front surface and a side surface, in Fig. 7 In, the drive shaft 21 by switching operating mechanism 20 switches the state of switching device 31,32 and 33 in positive side, passes through behaviour The operating shaft 11 for making unit 10 switches the state of switching device 31,32 and 33 in side side, and the two axis 11 and 21 one-tenth Plumbness.In this way, can be provided the user with a kind of in side progress state by increasing an individual operating unit 10 The possibility of switching provides the additional usage scenario of switching device group.

Specifically, operating unit 10 can be regard as an independent marketable product, the side wall of operating unit 10 is torn open It unloads down, it can be fixed together with switch operating mechanism 20 by fasteners such as bolts.

Herein, " schematic " expression " serving as examplea, instances, or illustrations " should not will be described herein as " showing Any diagram, the embodiment of meaning property " are construed to technical solution that is a kind of preferred or more having advantages.

The series of detailed descriptions listed above are illustrated only for possible embodiments of the invention, The protection scope that they are not intended to limit the invention, it is all without departing from equivalent embodiment made by technical spirit of the present invention or change It should all be included in the protection scope of the present invention.
