Abstract
The utility model provides a keyswitch and a keyboard using the same. The keyswitch includes a key cap which can move up and down and is provided with a space on the bottom; a support plate which is provided with two positioning holes; a switch which is arranged below the support plate; connecting bars; a magnetic element; a first metal plate which is arranged below the magnetic element; and a second metal plate. The second metal plate is arranged below the first metal plate, and is rotatingly connected with the first metal plate. The magnetic element uses a magnetic force to attract the second metal plate in a first state, and the first state makes the keyswitch in an off state. When a central force bearing end is pressed downward, the first metal plate and the second metal plate are pressed to resist the attraction of the magnetic force, and then the second metal plate actuates the switch, and finally the keyswitch is in an on state. Through the keyswitch, a key which uses the magnetic force as the driving force which is required in key cap reset is realized.
Description
Technical field
The utility model is relevant for key combination (keyswitch) and keyboard, refers to that especially a kind of magnetic attraction that utilizes is with as the key combination of keycap reset drives power and the keyboard of using this key combination.
Background technology
Except the portable apparatus that uses contact panel, with regard to the use habit of laptop, keyboard still is one of indispensable input equipment.But because the trend of laptop slimming, be applied to the demand that keyboard on the laptop also has slimming thereupon.

Embodiment
For making purpose, structure, characteristic and function thereof that further understanding arranged, cooperate embodiment to specify as follows now to the utility model.
With reference to the explosive view of figure 1, the key combination 10 of one of the utility model embodiment comprises the keycap 100 that can move up and down, and its bottom surface has space 103; Supporting bracket 105, it has two location hole 105b and opening 105a; Switch 107 is positioned at this supporting bracket 105 belows; Connecting rod (containing 109a and 109b) and pair of balanced connecting rod 119; Magnetic element 110; The first metallic plate 113a is positioned at magnetic element 110 belows; With the second metallic plate 113b.
Can embed printing inscription plate 101 on the keycap 100, after combination is accomplished, push printing inscription plate 101, can make keycap 100 to coming downwards to dead point, and the function of actuation switch 107 and this key combination 10.
Connecting rod (containing 109a and 109b) have two ends 109a be inserted in respectively these two location hole 105b (or be called axle bed, bearing) in, these two ends 109a is connected in central force side 109b, wholely becomes the shape shown in Fig. 1.
After the combination, magnetic element 110 is to embed to be placed in the space 103 of this keycap 100, therefore can be along with keycap 100 upper and lower motions.
All diagram institute's exposure like other, the second metallic plate 113b is positioned at below the first metallic plate 113a, with rotating mode and first metallic plate 113a binding.When key combination 10 was not stressed, this magnetic element 110 mats one magnetic force attracted this second metallic plate 113b to be in first state, and this first state makes this key combination 10 be in off-state (OFF).But when key combination 10 is stressed, cause central force side 109b stressed when downward; Then push this first metallic plate 113a and this second metallic plate 113b to the absorption of coercive force and away from; Make the second metallic plate 113b activate this switch 107, and make this key combination 10 be in conducting state (ON).
As shown in Figure 2 this first state makes this key combination 10 be in off-state (OFF), and this moment, all movable elements all were in a top dead-centre.As shown in Figure 3 this second state makes this key combination 10 be in conducting state (On), and this moment, all movable elements all were in a bottom dead centre.
In order to disclose the relation of element under the top dead-centre state of keycap 100 belows, Fig. 2 be key combination 10 shown in Figure 1 when keycap 100 is not stressed, all the other combination of elements state diagrams (that is element 100,101 do not omit show).What must explain is that under any state after the combination, magnetic element 110 is to be embedded in the space 103 of keycap 100.Like Fig. 2; The two ends of balanced connecting rod 119 are inserted respectively in the hole of axle bed on the supporting seat 105 (bearing); The two ends of connecting rod 109 are inserted respectively in the hole of location hole 105b; Magnetic element 110 is adsorbed with the first metallic plate 113a, and the first metallic plate 113a then becomes rotating mode to link with the second metallic plate 113b.
When external force applies pressure to keycap 100 or printing inscription plate 101; In order to disclose the relation of keycap 100 lower element under the bottom dead centre state; Fig. 3 is a key combination 10 shown in Figure 1 when keycap 100 is stressed, all the other combination of elements state diagrams (that is element 100,101 does not show).What must explain is that this moment, magnetic element 110 was to be still in the space 103 that is embedded in keycap 100.Like Fig. 3, different with Fig. 2, be to be parallel to supporting bracket 105 approximately under balanced connecting rod 119 these states, the central force side 109b of connecting rod 109 is stressed downward at this moment, the first metallic plate 113a and magnetic element 110 break away from.Relation is like Fig. 4, shown in Figure 5 in detail.
Fig. 4 is the profile of each critical elements (element 100,101, the 119 does not show) relation under the state shown in Figure 2, must explanation be, this moment, magnetic element 110 was to be embedded in the space 103 of keycap 100, key combination is in disconnection (Off).Like Fig. 4, the two ends 109a of connecting rod 109 inserts respectively in the hole of location hole 105b, the magnetic element 110 absorption first metallic plate 113a, and the first metallic plate 113a then becomes rotating mode to link with the second metallic plate 113b.Under this state, the end 113bb of the second metallic plate 113b does not pass this opening 105a, and fails to activate the switch 107 of its below.
Fig. 5 is the profile of each the critical elements relation under the state shown in Figure 3; Like Fig. 5; Stressed to coming downwards to bottom dead centre because of printing inscription plate 101 with keycap 100; The central force side 109b of connecting rod 109 thereby move downward to bottom dead centre makes the tail end of the first metallic plate 113a and the absorption that the bottom surface breaks away from magnetic element 110.Under this state, the first metallic plate 113a interlock, the second metallic plate 113b makes the end 113bb of the second metallic plate 113b pass this opening 105a, and activates the switch 107 below it.What must explain is that no matter be under the state of Fig. 4 or Fig. 5, magnetic element 110 all is to be in the space 103 of keycap 100, goes up or motion down with keycap 100.
Can be known that by above-mentioned narration the force side 109b of these central authorities is placed on the first metallic plate 113a, stressed when downward as central force side 109b, the first metallic plate 113a rotates an angle with respect to this magnetic element 110, and both are broken away from.
Under the variation of isotropism, the metallic plate that the first above-mentioned metallic plate 113a, the second metallic plate 113b are able to an individualism replaces, as long as this metallic plate can interact with magnetic element 110, the effect that reaches creation gets final product.Therefore, the key combination of this type of isotropism variation also is the protection range of the utility model.
Use above-mentioned key combination 10, another embodiment of the utility model is the keyboard that comprises this kind key combination 10, and this keyboard comprises a plurality of this kind key combination 10.
Cooperating diagram can understand the utility model by above-mentioned explanation can reach the purpose that creation sets really, therefore have practicality.
The utility model is described by above-mentioned related embodiment, yet the foregoing description is merely the example of implementing the utility model.Must be pointed out that the embodiment that has disclosed does not limit the scope of the utility model.On the contrary, change and the retouching in spirit that does not break away from the utility model and scope, done all belong to the scope of patent protection of the utility model.
