4The place finishes its whole displacement range.
In the following description, with using common Reference numeral to refer to parts common or that be equal to, unless the other requirement of context.
In Fig. 2 to Fig. 9, show first preferred implementation of push button rocker switch 10.Electric switch 10 comprises rocker switch mechanism 100, comprises the button parts of button boundary cap 200, resiliency urged assembly 300, drive conversion member 400 and main casing 500.Though the different parts in the switch of this embodiment are contained in the main casing 500 and install and isolation with convenient, should understand the part that this switch can be mounted to device or equipment.
Spring assembly is set in rocker switch usually.This spring assembly is arranged for the electrical contact member that promotes rocker component and makes it in a single day move to the stable operation position just to remain on this position.Spring assembly also plays in case just make contact member move to the dual-use function of next operating position when rocker component moves to critical threshold position.Usually, spring assembly comprises helical spring 140, this helical spring be assemblied in the ducted body of rocker component and its axis vertical substantially with rocker arm shaft 130.Certainly, other resiliency urged parts also can provide purposes identical or that be equal to.
Button parts comprises button member and button boundary cap 200.Button boundary cap 200 comprises the main body with contact surface 210.The upside of contact surface 210 and downside are respectively applied for the button member reciprocation and are used for moving downward of button member is passed to rocker component.The main body of button boundary cap 200 provides distributed contact surface, and this distributed contact surface is used for resiliency urged assembly 300 reciprocations and is used to provide the pivot to the pivoting action of the driving conversion member that will be described below to support.The main casing 500 that it should be noted that the main body of button boundary cap 200 and switch forms the cooperation guide member together, thereby button can change operating period along the predetermined direction turnover main casing that slides in pattern, that is, towards with away from the rocker component linear slide.
The elastic pushing device of present embodiment comprises the resiliency urged assembly 300 that is arranged between button boundary cap 200 and the rocker component 110.The resiliency urged assembly comprises first elastic device 320 and second elastic device 330.First elastic device 320 is used to provide the elastic recovery motive force, thereby button or button boundary cap will return initial spring neutral position or zero displacement position d from depressing position after released
0This first elastic pushing device is also by advancing towards rocker component at button but introduce the incremental resistive force of opposing button motion before running into rocker component, and help to alleviate the user in the process of actuation button formula rocker switch since the actuation force characteristics of rocker switch experience suddenly and coarse.By when rocker component moves, increasing resistance gradually at button, the height of resistive force step, promptly the unexpected step at d1 place will reduce, and the user will experience preferably " sensation ".
Thereby first elastic pushing device of this resiliency urged assembly 300 provides multiple use in the present invention.At first, the incremental resistive force that this first elastic pushing device provides opposing can cause the button motion that operator scheme changes, for example adjustable resistance.Specifically, the existence of this resistance makes the user all can feel resistance along the whole displacement range of button basically.Secondly, the first resiliency urged parts are provided for making button to return the elastomeric spring bias voltage of its zero displacement position when released.Additional incremental resistive force is provided the three, the first elastic pushing device so that the step gap turn narrow of rocking arm actuation force is as described below.Fig. 2 A, 2B, 2C and 2D show the embodiment of suitable resiliency urged assembly.Certainly, can adopt the resiliency urged assembly of other suitable form and not lose generality.And, when describing assembly in this manual, should be understood that and use this term just for convenience.Certainly, the resiliency urged assembly can form individual unit or distributed elements.
Second elastic pushing device 330 is used for moving towards rocker component at button but the additional elastic resistance of resisting button is provided before running into rocker component.This resistance is an increment, thereby the required additional actuation force of the inertia that overcomes rocker component or the step height of differential actuation force are reduced.
In order when still keeping compact design, from additional incremental resistive force, to be benefited, between button boundary cap 200 and rocker component 100, arrange to comprise the driving reforming unit that is used for the linear movement of button is changed into the driving conversion member 400 of rotation or pivot driver motion.
Shown in Fig. 2 A, an embodiment of resiliency urged assembly 300 comprises platform member 310 and a pair of spring member 320.This is arranged on the cross side of platform member below spring member.Each spring member all is a helical spring, and axle of spring is substantially parallel with the direction of actuation force, thereby when button down, helical spring is compressed.When button unclamped, the stored energy in the spring member can provide back stretch so that button return spring zero position.Certainly, can revise spring member stretches them rather than compresses during press-button actuated.Fig. 2 B represents the modification of resiliency urged assembly 300A, and the single helical spring that this modification has a center arrangement replaces the spring member of the lateral shift (laterally displaced) of Fig. 2 A.Helical spring can have the square-section rather than shown in circular cross-section.Fig. 2 C represents that example resilient promotes another modification of assembly 300B, and is wherein symmetrical and replace the spring member of Fig. 2 A from the flexible feet of metallic plate bifurcated with a pair of center about metallic plate.Fig. 2 D represents that the another example resilient that comprises platform member and a pair of flexible feet promotes assembly.In this design, described platform member and a pair of flexible feet are separable, and this helps adjusting separately the elastic force of two parts to strengthen flexibility.
For thereby the additional incremental resistive force that the opposing button is provided in the process of the operator scheme that changes rocker switch makes above-mentioned resistive force step or differential narrowing down, resiliency urged assembly 300 provides the additional springs device.This additional springs device is suitable for satisfying the requirement of the above-mentioned second elastic resistance device, and is called second spring assembly for convenience here.In this embodiment, platform member 310 is formed by the elastomeric material such as steel plate, and is made for metal sheet.Second spring assembly comprises that a pair of and metallic plate are integrally formed and is suspended in spring arm 330 on the metallic plate.As can be seen from Figure 2A, spring arm 330 engages with metallic plate at an one longitudinal end place and extends towards another longitudinal end of metallic plate.The free end of described a pair of spring arm is also approaching toward each other.In other words, the basic conllinear of described a pair of spring arm and parallel with the longitudinal axis of metallic plate.
Drive reforming unit and comprise that thereby the linear movement that is applicable to button changes into the driving conversion member (or being called for short pendulum shape member) 400 of pendulum shape that rotation or pivoting action help changing the operator scheme of rocker switch.Pendulum shape driving conversion member 400 comprises the main body 410 on the housing that is pivoted on button boundary cap 200.Form the shoulder 420 of a pair of chamfering slightly at the far-end away from pivot axis of main body 410.Shoulder 420 is carried out chamfering, make the far-end of main body tilt, thereby the external side of main body edge is shorter than the middle part of main body 410 away from the center line of main body.Shoulder is from the center line lateral shift of main body and always substantially about the pivot axis symmetry.This lateral symmetry helps having the symmetry operation of rocker switch of the type shown in Figure 1 of two operator schemes.
