Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Below in conjunction with accompanying drawing, the capacitive type touch pad parameter adjustment control of a conductive slider module and a "T"-shaped gathering sill of only establishing that the embodiment of the present invention provides is described in detail:
The present invention realizes like this, as shown in Figure 1, Figure 2 and Figure 3, capacitive type touch pad parameter adjustment control, comprise capacitance touch plate module 4, the circuit board 42 that described capacitance touch plate module 4 comprises fender 41 and is bonded in below fender 41, is provided with lower bolster 3, conductive slider module and upper padding plate 1 successively above described capacitance touch plate module 4; Wherein said lower bolster 3 is provided with a "T"-shaped gathering sill slidably reciprocated along described lower bolster 3 fore-and-aft direction for described conductive slider module, for single injection-molded structure, comprise middle groove 1, the left slideway 32 being positioned at described groove about 1 and right slideway 33; Described upper padding plate 1 is provided with the groove two 11 corresponding with groove 1 position on described lower bolster 3; Upper padding plate 1 is the fender towards user direction of this device, is made of plastics.Groove 1 and groove 2 11 position, size are corresponding, jointly form a "T"-shaped gathering sill, reciprocatingly slide back and forth for conductive slider module with left slip 32 and right slideway 33.
Described conductive slider module comprises conductive slider 21, metal clips 22 and PVC sheet 23; Described conductive slider 21 comprises interconnective head 211, neck 212 and bottom 213, and the head 211 of described conductive slider 21 is arranged in the groove 2 11 of described upper padding plate 1; Described neck 212 to the left and right direction extends a left flange and a right flange respectively, and the lower surface of described left flange and right flange is the movable upper surface fitting in left slideway 32 on described lower bolster 3 and right slideway 33 respectively; The bottom 213 of described conductive slider 21 is contained in the groove 1 of described lower bolster 3, and bottom 213 end face slightly contacts at the upper surface of the fender 41 of described capacitance touch plate module 4; Conductive slider 21 is made up of conductive material plastics, mixes the powder of conductive material during injection moulding, and the present embodiment is carbon dust, and these conductive powders are uniformly distributed in the plastic, thus makes slide block have good electric conductivity.The integrally-built design of conductive slider 21, echoes mutually with the structural design of "T"-shaped gathering sill, and both can coordinate well, and mating surface all does polishing, realizes the smooth and easy slip of conductive slider 21.
Be provided with hole in the middle of described metal clips 22 and PVC sheet 23, be sheathed on the head 211 of described conductive slider 21 respectively from top to bottom, the center section of described metal clips 22 is protruding upward to overarch.The disposable impact briquetting of metal clips 22, is between PVC sheet and conductive slider 21.When assembling, upper padding plate 1 gives metal clips 22 1 pressure by PVC sheet 23, and it is slightly out of shape, thus produces an elastic force by PVC sheet 23 to upper padding plate 1 direction jack-up, makes PVC sheet 23 and Upper gasket 1 close contact.Meanwhile, by conductive slider 21 to the pressure of lower bolster 3 direction, ensure that conductive slider 21 has certain resistance when sliding, forming good feel, also ensure that conductive slider can not rock in sliding process.
Particularly, as shown in Figure 1, the head 211 of described conductive slider 21 and the cross section of bottom 213 are in square, rectangle, ellipse or circular, and the cross section of neck 212 is rectangle or oval arc.The each several part shape of conductive slider 21 contributes to the slip in gathering sill.
Particularly; as shown in Figure 1; described fender 41 is made up of the plastic plate insulating; play the effect of isolation and protection circuit board 42; circuit board 42 is the sensing circuit plates 42 of the pattern being printed on capacitive type touch pad function; it has the control circuit of capacitance touch, material is conventional printed circuit board (PCB), as FR4.
Particularly; as shown in Figures 2 and 3, conductive slider 21 and fender 41 can gentle touchdown, in the distance that also can be able to sense at touch pad; have few distance from fender slightly, bottom described conductive slider 21 with the spacing of fender 41 for being not more than 2 millimeters.Described PVC sheet 23 thickness is not more than 0.5 millimeter, and described metal clips 22 is become by stainless steel or copper, and thickness is not more than 0.3 millimeter.Ensure the light and good touch-sensitive properties of total, slidably reciprocating by conductive slider 21 during operation, is delivered to circuit board 42 by sense of touch by fender 41, has good sensitivity and precision.
Particularly, as shown in Figure 1, the surface smear that neck 212 lower surface of described conductive slider 21 and the left slideway 32 of described lower bolster 3 contact with right slideway 33 has lubricating oil.The surface smear that the lower surface of described upper padding plate 1 contacts with PVC sheet 23 has lubricating oil.Ensure that conductive slider 21 slidably reciprocates smooth and easy in the "T"-shaped gathering sill of lower bolster 3, flexible operation and precision is high.
Principle of work and the effect of sliding damper of the present invention are as follows:
Conductive slider 21 is placed in the "T"-shaped gathering sill of lower bolster 3, slidably reciprocates along "T"-shaped gathering sill.Conductive slider 21 is moving components unique in capacitive type touch pad parameter adjustment control, when user press...withes one's finger conductive slider 21, staff is worked by conductive slider 21 pairs of capacitance touch plate module 4, just as with finger contact capacitance touch plate module 4, capacitance touch plate module 4 just can detect the position of conductive slider 21, and different positions correspond to different regulating parameter.Position coordinates is calculated by the chip of circuit board 42, and by communication interface as SPI or I2C gives the microprocessor of system.Thus make microprocessor can process corresponding parameter value further, reach the effect of adjustment.
When reality uses this device, when conductive slider 21 or fender 41 having steam or slight water mark, the material due to both is plastics, so can not go bad easily, also can not affect the use of this device.Relatively traditional slide rheostat will greatly extend its serviceable life.
Because the material of this device is cheap, structure is simple.After the size of capacitance touch plate module 4 is determined, often increase a conductive slider module of the present invention, only need to reserve a "T"-shaped gathering sill and groove 2 11, the increase of cost is only the plastics of formation conductive slider 21, PVC sheet 23 and metal clips 22 more.The conductive slider module needed when an equipment is more, and advantage of low cost of the present invention is more outstanding.
In conjunction with the state-of-the-art technology of capacitive type touch pad, the ability that its multiple spot can be utilized simultaneously to respond to, realizes multiple slide block and regulates simultaneously.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
