The operation principle of the present embodiment is in that:
A. function is pressed down on, moved downward by pressing keys cap 101, power is transmitted to the knob axis of guide 106, the knob axis of guide 106 drives upper circuit board 104, upper electric silica gel 105 and knob body are moved downward along the gathering sill 31 (Fig. 9) on bracing frame 3 by the guiding rib 111 (Fig. 8) on the knob axis of guide 106, owing to bracing frame 3 maintains static, upper electric silica gel 105 can be extruded by bracing frame 3, conductive layer until the conduction carbon plate on upper electric silica gel 105 and upper circuit board 104 contacts, so that circuit is in the conduction state, finally realize the signal output of circuit, realize function.
B. knob spinfunction, the center of the cylinder formed with 8 the rotary steering ribs 110 (Fig. 8) on the knob axis of guide 106 is for rotating shaft, by rotary knob body 108, the centre making the optical pickocff 109 (Fig. 7) on upper circuit board 104 of the barricade 113 (Figure 13) in knob body 108 rotates, barricade 113 on certain angulation knob body 108 can block the light receiver (Fig. 7) that self is sent by the optical pickocff 109 on upper circuit board 104 simultaneously, thus realizing the break-make of circuit, finally realize the signal output of circuit, realize function. in rotary course, knob body 108 is non-interference with the knob axis of guide 106.In the process of rotary knob body 108, sense of touch shell fragment 107 (Figure 12) can be constantly subjected to the extruding of the upper V-groove 112 of the knob axis of guide 106 (Fig. 8), when the lowest point of V-groove 112, the pressure being subject to of sense of touch shell fragment 107 can reach minimum, when the paddy peak of V-groove 112, the pressure being subject to of sense of touch shell fragment 107 can reach maximum, circulation change thereby through the shape formation power of V-groove 112, realize the sense of touch of operation knob, allow user feel the change of gear.The parameter of shape and the sense of touch shell fragment 107 adjusting V-groove 112 can be passed through, it is possible to reach the circulation change of different power simultaneously, and reach the sense of touch of different operation knobs, meet the demand of different clients.
nullC. eight to stirring function,By stirring knob body 108,Power is transmitted on knob assembly 1,Guiding rib 111 (Fig. 8) on the knob axis of guide 106 inside knob assembly 1 transfers force to stir shaft-cup 5 by the gathering sill 31 on bracing frame 3,Transfer force on shifting shaft 10 by stirring shaft-cup 5,Shifting shaft 10 can rotate (Figure 11) around rotation axis 100 (Figure 10) on shifting shaft pallet 12,Transferred force on drive block 15 by the rotation of shifting shaft 10,Owing to main circuit board 13 maintains static,Lower electric silica gel 14 can be subject to from drive block 15 extruding upwards,Conductive layer until the conduction carbon plate on lower electric silica gel 14 and main circuit board 13 contacts,So that circuit is in the conduction state,Finally realize the signal output of circuit,Realize function.Owing to shifting shaft 10 has eight rotation axiss 100, it is possible to stir to eight directions.In the rotary course of shifting shaft 10, spring 8 can be subject to sealing the extruding of lid 6 and metal dish 7, the compression stress of spring 8 can increase along with the stirring angle increase of knob body 108, the operating physical force simultaneously stirring knob body 108 also increases therewith, thus realizing stirring the sense of touch of knob.By adjusting the parameter of spring 8, it is possible to achieve the sense of touch of different operation knobs meets the demand of different client.
D. backlight function, owing to main circuit board 13 is connected with upper circuit board 104 by flexible harness 9, so main circuit board 13 can provide power to circuit board 104.When arranging LED on upper circuit board 104, LED will be luminous under the supply of power supply.By adjusting the color of LED and being supplied to the electric current of LED, client will obtain the backlight of different colours and the backlight of different brightness, improves the comfort property of user.
The benefit and the advantage that adopt technique scheme are in that: the multifunctional steam stopping switch described in the present embodiment, it is possible to realize the integrated of multiple function in limited space, and advantageously reduce enterprise's manufacturing cost.Different backlight demands can be provided for different clients, allow user be easier to operate to switch when driving at night, make driving safer.The present invention can also provide the feel of the operation button of differentiation according to different clients, improves the comfortableness used.In addition electric silica gel wraps up the design of circuit board entirely, makes circuit board be in the environment of sealing, it is also possible to the effectively erosion of exclusion of water gas and dust.
