Detailed description of the invention
As shown in Figure 7, on the keyboard switch that the utility model proposes switchs based on existing common keyboard, in being located at pedestal 2 including: pedestal 2, fixing upper cover 22 on the base 2, bottom and moving up and down lead core 3, be arranged on the spring 4 led between core 3 and pedestal 2 and cover at the keycap 1 leading core 3 top.
As shown in Figure 8,9, leading and be provided with lower mounting post 33 in the middle of the end face of core 3, lower mounting post 33 is cross column, the bottom surface of keycap 1 is provided with mounting post 11, the profile of upper mounting post 11 is cross column or cylinder, and upper mounting post 11 bottom surface is provided with mounting groove, and mounting groove is the cross recess coordinated with cross column.The end face of upper cover 22 is provided with sliding eye 21, leading stretches in pedestal through sliding eye 21 bottom core 3, lead core 3 during pressing keycap 1 to move up and down along sliding eye 21, sliding eye 21 generally slot, it is horizontal for being perpendicular to the direction of two relative hole walls close together on sliding eye 21, being perpendicular to the direction of two distant relative hole walls on sliding eye 21 is longitudinally, the transverse width of upper mounting post 11 is (when upper mounting post is cross column, its transverse width is the length of straight flange that length is shorter, when upper mounting post is cylinder, its transverse width is the diameter of cylinder) and the transverse width matched in clearance of sliding eye 21, the longitudinal length of upper mounting post 11 is less than the longitudinal length of sliding eye 21.Seeing Fig. 5 of prior art, when leading core 3 and being in pressed state, upper mounting post 11 is filled in sliding eye 21, but still suffers from bigger cavity between two ends and the upper mounting post 11 of length direction in sliding eye 21, and dust is easily collected in this cavity and falls in pedestal 2.
Said structure is identical with common keyboard construction of switch on the market.
Such as Figure 10, shown in 11, this utility model is provided with a pair dust excluding plate 34 in the end face lateral symmetry leading core 3, as shown in Figure 12,13, cavity between dust excluding plate 34 and lower mounting post 33 can accommodate mounting post 11 grafting, the outermost distance of dust excluding plate 34 is coordinated by this with the length space of sliding eye 21, and the width of dust excluding plate 34 coordinates with the width gaps of sliding eye 21.Such as Figure 14, shown in 15, lead core 3 when being in pressed state, dust excluding plate 34 fills upper mounting post 11 and the cavity at length direction two ends in sliding eye 21, dust is prevented to be collected in the cavity between mounting post 11 and sliding eye 21, dust is effectively stoped to enter in pedestal 2, the end face of dust excluding plate 34 is not less than the end face of sliding eye 21, and dust cannot fall in sliding eye 21 when pressing, and anti-dust performance is more preferable.
In one embodiment, as shown in figure 16, this is the arc surface of indent to dust excluding plate 34 towards relative wall, dust excluding plate 34 thickness of this structure is big, intensity is high, dustproof construction is stablized firm, but shrinking deformation easily occurs during injection molding, and dust excluding plate 34 is poor with the fitness of sliding eye 21.In another embodiment, as shown in figure 17, the two ends of dust excluding plate 34 form opening along the direction bending being perpendicular to interlude, this to the opening of dust excluding plate 34 towards relatively, dust excluding plate 34 thickness of this structure is uniform, being not susceptible to shrinking deformation during injection molding, dust excluding plate 34 is higher with the fitness of sliding eye 21.
Being provided with spring stack 31 bottom core 3 as it is shown in fig. 7, lead, the inner bottom surface of pedestal 2 is provided with lower spring post 23, and the two ends of spring 4 are respectively fitted on spring stack 31 and lower spring post 23.The both sides, top leading core 3 are provided with spacing block set 32, and spacing block set 32 is positioned at upper cover 22, and when keycap 1 is in releasing orientation, spacing block set 32 abuts with sliding eye 21, limit and lead the upper limit that core 3 is upspring.Lead the movable block that the both sides outer wall of core 3 protrudes above, be provided with in pedestal 2 and can accommodate the stopper slot 24 that movable block moves up and down, make the up and down motion leading core 3 more accurate.
Lead core 3 top to be not provided with the side of spacing block set 32 and be provided with the outwardly directed sloping platform of bottom angled 35, the shell fragment 5 relative with this sloping platform 35 position it is provided with in pedestal 2, shell fragment 5 two ends doubling, the junction at two ends is transition arc, one end of shell fragment 5 is fixing on the base 2, sloping platform 35 is arranged by other end, on shell fragment 5, this face towards sloping platform 35 is provided with the bending part 51 of protrusion, leads core 3 when moving up and down in pedestal 2, and sloping platform 35 contacts with bending part 51 and promotes shell fragment 5.
Such as Figure 13, shown in 15, being additionally provided with stator 6 in pedestal 2, stator 6 is located at the lower section of sloping platform 35 and staggers with sloping platform 35 in position, interferes with stator 6 avoiding leading sloping platform 35 when core 3 moves.Stator 6 is provided with boss 61, boss 61 is provided with stationary contact, shell fragment 5 is provided with movable contact 52, when sloping platform 35 does not contacts with the bending part 51 on shell fragment, this stationary contact abuts with movable contact 52, by the stationary contact on stator and the contacting or disconnection of movable contact on shell fragment, the output signal of telecommunication is to keyboard, it is achieved being turned on and off of keyboard switch.
As shown in figure 18, in order to make keyboard switch more have feel when pressing, the middle part of sloping platform 35 is provided with the recess 39 coordinated with bending part 51, lead core 3 when being in original state, bending part 51 is positioned at this recess 39, sloping platform 35 is during moving downward, and the amplitude of variation that recess 39 pushes bending part 51 open is relatively big, makes staff experience keycap 1 by the change of surging.
Such as Figure 19, shown in 23, in order to make keyboard switch not only have feel and have sound, leading core 3 and led core 37 by leading core 36 and the pair that is enclosed within leading core 36 and constitute, pair leads core 37, and in lid and Open Side Down, such as Figure 20, shown in 21, sloping platform 35 is arranged on pair and leads on the outer wall of core 37.The both sides, top of leading core 36 are additionally provided with the buckle 38 being positioned at below spacing block set 32, and pair leads the end face of core 37 between spacing block set 32 and buckle 38, and pair is led the both sides inwall of core 37 and is provided with and can accommodate the chute that buckle 38 moves up and down.
As shown in Figure 22,23,24, leading core 36 is pressed down on during use, spacing block set 32 on leading core 36 moves down and promotes pair to lead core 37 and moves down, after the recess 39 of sloping platform 35 pushes bending part 51 open, sloping platform 35 continues to move downward, the bending part 51 of shell fragment resets under the effect of restoring force, and promotes sloping platform 35 sharp downward movement, and now the inner top surface of chute clashes into buckle 38 and sends sound.
Further optimizing, as it is shown in fig. 7, the position, outer ring of pedestal 2 is also equipped with a light-emitting component 7, keycap 1 covers the top of light-emitting component 7, and the profile not only making keyboard switch is more attractive, moreover it is possible to facilitate keyboard switch to use at night.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
