Abstract

The invention discloses a key structure and a switch structure using a magnetic attraction force as a restoring force, and a key structure combination method. According to the key structure and the switch structure, a bracket providing a keycap support and actuation mechanism and another bracket interacting with the bracket through a magnetic attraction force are arranged between a base and a keycap. When the keycap is not subject to external pressure, the magnetic attraction force drives the two brackets to be arranged on the base stably to form a stable support structure, and the keycap is in a farther position relative to the base. When the keycap moves to the base under external pressure, the magnetic attraction force is overcome by the external pressure, and the two brackets are separated. After the keycap is pressed, a pair of switch contacts of the base is switched on by the other bracket. Once the external force is gone, the two brackets can form a stable support structure again under a magnetic attraction force.

Additionally, both ends 842a, 842b of first support 842, that is, the top and bottom of first support 842 difference is rotatable Be connected to the connecting portion 802 of keycap 80, its hiding profile be illustrated in Figure 20 with dotted line and base 82 connecting portion 826, Positioned at the inner surface of upper cover part 824, its hiding profile is illustrated in Figure 20 with dotted line, the both ends 844a of second support 844, 844b that is, the top and bottom of second support 844, are respectively rotatably connected to the connecting portion 804 of keycap 80, and connecting portion 804 is hidden The profile of Tibetan be illustrated in Figure 20 with dotted line and base 82 connecting portion 828；Wherein, connecting portion 828 is directly arranged at upper cover part 824 outer surface, and strictly speaking connecting portion 826 is by the inside structure of upper cover part 824 and lower board unit 822 or circuit board 8224 It is collectively forming, but also can be alone formed by upper cover part 824 on being embodied as.First support 842 includes the first magnetic part 8422, Such as first support 842 is embedded in plastic cement support body 8420 and is formed by Magnet as the first magnetic part 8422.3rd support 86 is included The second magnetic part 862, supporting part 864 and the adjutage 866 being connected with each other, the 3rd support 86 also includes trigger unit 866a, and it sets The free end of adjutage 866 is placed in, supporting part 864 and trigger unit 866a are respectively positioned at the two opposite sides of the 3rd support 86.3rd Support 86 is rotationally arranged on base 82 with supporting part 864, and the second magnetic part 862 is located at the magnetic part of keycap 80 and first Magnetic attraction F3 (being shown in Figure 21 with double-head arrow) is produced between 8422 and between the first magnetic part 8422.In the present embodiment In, the 3rd support 86 and the first magnetic part 8422 are respectively positioned in accommodation space 820, first switch contact 8224a and second switch Contact 8224b is also located in accommodation space 820, and the upper end of first support 842 is extended in upper cover part 824 equivalent to end 842a Just connect keycap 80.So upper cover part 824 can reduce extraneous magnetic conductivity foreign body, for example：Steel wire or iron filings, by magnetic attraction F3 Attract and enter the chance between the second magnetic part 862 and the first magnetic part 8422 so that between the support 86 of first support 842 and the 3rd Lifted as dynamic stability, and then make between the 3rd support 86 and first switch contact 8224a and second switch contact 8224b Reliability in electrical contact also lifted.

In addition, on being embodied as, if press-key structure 8 has extra dust-proof mechanism, for example：When press-key structure 8 is applied In keyboard, there is keyboard elastic film to be pasted onto keycap 80 and keyboard case upper surface, and elastic film extends over key Both cap 80 and housing gap, then upper cover part 824 also can omit；So first support 842 and second support 844 also can directly connect Lower board unit 822 or base plate 8222 are connected to, such as base plate 8222 is metallic plate, and direct punching press folds upwards the He of similar connecting portion 826 There is 828 attachment structure, circuit board 8224 corresponding through hole to pass through by attachment structure, in order to first support 842 and second Support 844 is connected with base plate 8222.

In the present embodiment, the adjutage 866 of the 3rd support 86 is located between keycap 80 and base 82 and positioned at keycap 80 Between first support 842, when keycap 80 is pressed by external force F0 (being depicted with arrows in Figure 22) and moved towards base 82, First support 842 is subject to the gearing of keycap 80 and moves towards base 82, and the 3rd support 86 is subject to magnetic attraction F3 to the second magnetic The sucking action in portion 862 is also moved down, as shown in Figure 21 to Figure 23.In other words, magnetic attraction F3 orders about the direction of the 3rd support 86 Base 82 is moved and keeps being connected to first support 842, i.e., the 3rd support 86 is forced in first support 842.Wherein, in concrete In enforcement, press-key structure 8 is typically perpendicular to be put, therefore the 3rd support 86 also receives in principle own wt and has what is moved down to become Gesture.

Additionally, referring to shown in Figure 24, in the present embodiment, the 3rd support 86 also includes two force sections 868 and two Individual gap 870, two force sections 868 are located at respectively the two opposite sides of the 3rd support 86, and adjutage 866 is located at two force sections 868 Between and with two force sections 868 be respectively separated a gap 870.As shown in figure 20, in the present embodiment, first support 842 U-shaped breach 842c and two ends, i.e. end 842b are further included, in other words the lower end of first support 842, aforementioned two ends are located at respectively U-shaped Breach 842c two opposite sides.Adjutage 866 is extended in U-shaped breach 842c and downwardly second switch contact 8224b prolongs Stretch；Two force sections 868 are respectively extended from the center line two opposite sides of first support 842, and can more fifty-fifty force in first On frame 842.

As shown in figure 21, when keycap 80 by external force F0 press when, keycap 80 positioned at non-pressing position be initial position when, Magnetic attraction F3 causes the first magnetic part 8422 and the second magnetic part 862 to keep trend close to each other so that first support 842 and 3rd support 86 is stably arranged on base 82, and makes keycap 80 be maintained at non-pressing position.When keycap 80 is pressed by external force F0 And from non-pressing position (as shown in figure 21) move downwardly toward trigger position is (as shown in figure 22) when, the first magnetic part 8422 and the Two magnetic parts 862 are located remotely from each other, and magnetic attraction F3 orders about the 3rd support 86 and rotates around supporting part 864, and trigger unit 866a direction Base 82 is moved；Wherein, the second magnetic part 862 is located between supporting part 864 and trigger unit 866a, therefore in keycap 80 towards base During 82 movement, the 3rd support 16 rotates generally centered on supporting part 864, and then trigger unit 866a is opened towards second Coila 8422b is moved.

In the present embodiment, the 3rd support 86 is made with single metal plate part, therefore both trigger unit 866a and supporting part 864 Between electrically conduct；And supporting part 864 keeps being connected to first switch contact 8224a, that is, supporting part 864 keeps in electrical contact the One make and break contact 8224a.As shown in figure 22, when keycap 80 drops to trigger position, order about trigger unit 866a move down and Second switch contact 8224b in electrical contact so that first switch contact 8224a and second switch contact 8224b electrically conduct.

As shown in figure 22, keycap 80 moves to trigger position.Though contact second switch contact 8224b in trigger unit 866a Afterwards, first support 842 can continue to be rotated with moving down for keycap 80, but the two ends of the 3rd support 86 or so are supported respectively Second switch contact 8224a, 8224b are met, therefore the 3rd support 86 is no longer accompanied by principle the synchronous rotary of first support 842, makes Adjutage 866 separates with first support 842；Therefore in keycap 80 by external force F0 from trigger position continuation (as shown in figure 22) bottom of towards Seat 82 is moved to during pressing position (as shown in figure 23), with the first magnetic part 8422 and the second magnetic part 862 between the two Distance increases so that magnetic attraction F3 can be gradually reduced.Therefore the first enough magnetic part 8422 of magnetic attraction and the second magnetic to be selected Suction portion 862, during guaranteeing that keycap 80 is located at pressing position, still has enough magnetic attraction F3 to be enough to make on keycap 80 between two magnetic parts Rise and be returned to non-pressing position.

When downward external force F0 of pressing keycap 80 disappears, such as user finger is moved away from keycap 80, and magnetic attraction F3 is ordered about First magnetic part 8422 is close with the second magnetic part 862 so that keycap 80 is replied from relatively low pressing position, through trigger position To higher initial position, i.e., the position that keycap 80 is not pressed, that is, the non-pressing position and first support 842 and the 3rd Support 86 contacts and is stably arranged on base 82, as shown in figure 21.

In principle, when keycap 80 is located between non-pressing position and trigger position, the 3rd support 86 is by two forces Portion 868 and force in first support 842；On being embodied as, because adjutage 866 can be with two by two gaps 870 Force section 868 has different deflections, or that sag curve (deflection curve), therefore can be by designing adjutage 866 with the structure of force section 868 so that when trigger unit 866a has just contacted second switch contact 8224b, there is provided one section of strength is delayed Punching is interval so that when keycap 80 continues to move down, and two force sections 868 still keep being connected to first support 842, but while Adjutage 866 deforms relatively upward, and then to second switch contact during mitigation trigger unit 866a contact second switch contact 8224b The shock force of 8224b triggers force, therefore can increase the fatigue durability of adjutage 866, that is, lift adjutage 866 elastic Flexural deformation is so that the durability of trigger unit 866a contact second switch contact 8224b, also can maintain second switch contact simultaneously The naked copper layer of the surface texture of 8224b, such as weld pad or thereon possible coating, can extend making for second switch contact 8224b Use the life-span；For example according to beam theory (Timoshenko beam theory), will prolong relative to the moment of inertia of two force sections 868 The moment of inertia of semi-girder 866 or two secondary axes squares are designed to relatively small, you can realize object defined above easily.

In addition, referring to Figure 25；Wherein, the 3rd support 86 its profile is illustrated in figure with dotted line, to show the 3rd The syntagmatic of frame 86 and upper cover part 824.In the present embodiment, the inner face of upper cover part 824 has the first snap-in structure 830, supports Portion 864 has the second snap-in structure 8642 (being shown in Figure 24 with dotted line frame), and the 3rd support 86 is around the first snap-in structure 830 and the The junction of two snap-in structure 8642 rotates.Furthermore, it is understood that in the present embodiment, the first snap-in structure 830 includes groove 830a And the protruded stigma 830b in groove 830a, the second snap-in structure 8642 is comprising hole 8642a and positioned at the two of the both sides of supporting part 864 Individual kink 8642b.Supporting part 864 is resisted against on first switch contact 8224a so that the second snap-in structure 8642 is overall can be protected Hold in groove 830a, wherein protruded stigma 830b passes through hole 8642a, remove in kink 8642b structures and coordinate with groove 830a, also Coordinate with first switch contact 8224a, be respectively provided with spacing effect, also contribute to lifting the degree of stability of the start of the 3rd support 86, its In, first switch contact 8224a is in integrally a zigzag structure.

As indicated above, the actuation mechanism of press-key structure 8 is substantially the same with press-key structure 1, especially with respect to first Interaction between the support 86 of frame 842 and the 3rd, based on magnetic attraction F3, therefore with regard to other explanations and its change of press-key structure 8, can join The explanation previously with regard to press-key structure 1 and its change case is read, is not separately repeated.For example previously for fourth embodiment, i.e. elevator Structure 14 is not separately repeated by illustrating also there is applicable in this only by taking first support 14 as an example.

In addition, in the present embodiment, first switch contact 8224a and second switch contact 8224b are via the 3rd support 86 integrally turn on, non-only to be realized by trigger unit 866a, but the present invention is not limited.Referring to Figure 26, according to Figure 26 The explosive view of the press-key structure of another embodiment.For purposes of illustration only, the press-key structure shown in Figure 26 is roughly the same with press-key structure 8 And the component symbol of press-key structure 8 is continued to use, therefore illustrate with regard to the press-key structure shown in Figure 26 other, comprising the 3rd support 86 Start, refers to the related description of press-key structure 8, does not separately repeat.Additionally, to simplify and the difference in structure of press-key structure 8, The present embodiment still retains the Z-shaped support 832 being welded on circuit board 8224, its only for the 3rd support 86 supporting part 864 against, Itself is without electrical purposes.Press-key structure shown in Figure 26 is with the Main Differences of press-key structure 8, first switch contact 8224a and Second switch contact 8224b is respectively positioned on the same side of the 3rd support 86 and is directly formed by the weld pad on circuit board 8224, therefore works as When keycap 80 reaches trigger position, trigger unit 866a is while first switch contact 8224a in electrical contact and second switch contact 8224b, can equally turn on first switch contact 8224a and second switch contact 8224b.In the present embodiment, the 3rd support 86 The surface that only first switch contact 8224a and second switch contact 8224b need to be contacted in trigger unit 866a has electric conductivity, 3rd support 86 can use non-metallic material, and such as macromolecular material makes, and its second magnetic part 862 can be another gold of adhesion Category piece or Magnet.
