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.

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

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
