Description
Technical Field
The present invention relates to a key, and more particularly, to a key which provides a key reset force by interference of supporting plates.
Background
In terms of the current usage habit of personal computers, a keyboard is one of the indispensable input devices for inputting characters, symbols or numbers. Moreover, for example, consumer electronic products in contact with daily life or large processing equipment used in the industry, a key structure is required to be provided as an input device for operating the electronic products and the processing equipment.
Generally, the conventional keyboard adopts a pressing design in which an assembly structure of the scissor-foot supporting device and the elastic member is disposed between the key cap and the bottom plate, so that when the key cap is pressed by a user, the elastic member provides an elastic restoring force to the key cap to drive the key cap to return to a position before pressing along with the mechanism of the scissor-foot supporting device. However, the design of the scissor mechanism adopted by the scissor support device causes the keys to require a large height space, which is not favorable for the application of thinning the keyboard. In addition, since the elastic member is usually made of rubber, the rubber will be fatigued after long-term use, and the service life of the key is shortened.

Detailed Description
The foregoing and other aspects, features and advantages of the invention will be apparent from the following more particular description of a preferred embodiment, as illustrated in the accompanying drawings. Directional terms as referred to in the following examples, for example: up, down, left, right, front or rear, etc., are referred to only in the direction of the attached drawings. Accordingly, the directional terminology is used for purposes of illustration and is in no way limiting.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic partial exploded view of a key 10 according to an embodiment of the present invention, fig. 2 is a schematic exploded view of the key 10 in fig. 1, and the key 10 can be preferably applied to a general portable electronic device (such as a notebook computer) having an opening and closing mechanism composed of an upper cover and a lower housing, but not limited thereto. As shown in fig. 1 and 2, the key 10 includes a base 12, a key cap 14, and a supporting device 16. The base 12 has at least one first pivot portion 18 and at least one second pivot portion 20 (two are shown in fig. 1, but not limited thereto), and the keycap 14 is disposed above the base 12. The supporting device 16 is disposed on the bottom plate 12 and supports against the key cap 14, the supporting device 16 includes a first supporting plate 22 and a second supporting plate 24, the first supporting plate 22 and the second supporting plate 24 can be made of a metal material and have substantially the same supporting plate structure (but not limited thereto) to facilitate the manufacture of the supporting device 16, the first supporting plate 22 and the second supporting plate 24 are opposite to each other and have a first bottom edge 26 and a second bottom edge 28, respectively, the first supporting plate 22 is pivotally connected to the first pivot portion 18, the second supporting plate 24 is pivotally connected to the second pivot portion 20, the first supporting sheet 30 extends from the first bottom edge 26 to the second supporting plate 24 to support against the second bottom edge 28, and the second supporting sheet 32 extends from the second bottom edge 28 to the first supporting plate 22 to support against the first bottom edge 26 and is offset from the first supporting sheet 30, thereby, the key cap 14 can move up and down between the non-pressed position and the pressed position along with the supporting device 16 through the pivoting of the first supporting plate 22 and the second supporting plate 24 relative to the base plate 12, respectively.
In more detail, in this embodiment, the first pivot portion 18 may preferably be a bent hook protruding upward from the base plate 12, the first support plate 22 may form a receiving hole 34 corresponding to the bent hook, and the first pivot portion 18 may be snapped into the receiving hole 34 to pivotally connect the first support plate 22 to the base plate 12. Furthermore, the first supporting plate 22 can be recessed downward toward the first pivot portion 18 at the portion corresponding to the receiving opening 34 to form a concave structure 36 (e.g., formed by stamping and punching), so that the present invention not only can increase the structural rigidity of the first supporting plate 22, but also can reduce the assembly height of the first supporting plate 22 pivoted on the bottom plate 12 to facilitate the slim design of the key 10.
As for the switch triggering design, the invention can adopt a convex hull structure to press against the triggering switch, for example, as shown in fig. 1 and fig. 2, the bottom plate 12 can be protruded to form a convex hull elastic body 38 at a position between the first supporting plate 22 and the second supporting plate 24, and the key 10 further comprises a triggering switch 40, wherein the triggering switch 40 is connected to the keycap 14 at a position corresponding to the convex hull elastic body 38. In this way, when the key cap 14 is pressed to the pressing position by an external force, the convex hull elastic body 38 can press the trigger switch 40, so that the key 10 performs the corresponding input function; on the other hand, when the external force is released, the compressed convex hull elastic body 38 can provide an elastic force to drive the keycap 14 to return to the non-pressed position to generate a self-returning effect, so that the user can perform a subsequent key pressing operation.
In addition, as shown in fig. 2, the bottom plate 12 is bent toward the first supporting plate 22 to form at least one folding structure 42 (four are shown in fig. 2, but not limited thereto), so that when an external force presses the key cap 14 to the pressing position, the folding structure 42 can stop the first supporting plate 22 from pivoting relative to the first pivot portion 18, so as to prevent the first supporting plate 22 from being excessively pivoted to damage the internal components of the key 10. In addition, in order to prevent the supporting plate from excessively pivoting downward under the influence of gravity when the supporting plate is not pressed by force, the first supporting plate 30 may extend laterally to form a stopping ear 44, and the supporting plate 46 may be formed at a position of the bottom plate 12 corresponding to the stopping ear 44, whereby, when the key cap 14 is located at the non-pressed position as shown in fig. 1, the supporting plate 46 may support the stopping ear 44 to limit the first supporting plate 22 from pivoting downward relative to the bottom plate 12, thereby preventing the first supporting plate 22 from colliding with other components (such as the bottom plate 12) of the key 10 to generate structural noise or damage to the components. It should be noted that the above-mentioned configurations of the receiving openings, the recessed structures, the folding structures and the supporting and limiting designs of the stopping ears and the supporting pieces can also be applied to the second supporting plate 24, and the related description can be analogized from the above description, and will not be described herein again.
In practical applications, as shown in fig. 1, the bottom plate 12 may extend outward to form at least one bending hole piece 48 (four are shown in fig. 1, but not limited thereto), and the key cap 14 may protrude outward to form a limiting ear 50 corresponding to one side of the bending hole piece 48, so that the limiting ear 50 is detachably inserted into the bending hole piece 48 to limit the key cap 14 to support on the first supporting plate 22 and the second supporting plate 24, thereby reliably preventing the key cap 14 from shaking during the pressing operation or from accidentally falling off from the first supporting plate 22 and the second supporting plate 24.
Referring to fig. 3, fig. 4, fig. 5, and fig. 6, fig. 3 is a schematic cross-sectional view of the key 10 along a section line a-a in fig. 1, fig. 4 is a schematic cross-sectional view of the key 10 along a section line B-B in fig. 1, fig. 5 is a schematic cross-sectional view of the key cap 14 in fig. 3 pressed to a pressed position, and fig. 6 is a schematic cross-sectional view of the key cap 14 in fig. 4 pressed to the pressed position. When the key cap 14 is not pressed, the first supporting sheet 30 supports against the second bottom edge 28 of the second supporting plate 24 and the second supporting sheet 32 supports against the first bottom edge 26 of the first supporting plate 22, so that the key cap 14 is maintained at the non-pressed position as shown in fig. 3 and 4. When the key cap 14 is pressed to the pressing position by an external force, the first supporting plate 22 pivots relative to the base plate 12 with the first pivot portion 18 as a fulcrum, and the second supporting plate 24 pivots relative to the base plate 12 with the second pivot portion 20 as a fulcrum, in the process, the first supporting sheet 30 swings upward against the second bottom edge 28 with the pivot of the first supporting plate 22, and the second supporting sheet 32 swings upward against the first bottom edge 26 with the pivot of the second supporting plate 24 (at the same time, the first supporting sheet 30 interferes with the second bottom edge 28 to bias the second supporting plate 24 to flex and deform to generate an elastic restoring force, and the second supporting sheet 32 interferes with the first bottom edge 26 to bias the first supporting plate 22 to flex and deform to generate an elastic restoring force), so that the key cap 14 can move downward from the non-pressing position shown in fig. 3 and 4 to the pressing position shown in fig. 5 and 6 with the pivot of the first supporting plate 22 and the pivot of the second supporting plate 24, so that the trigger switch 40 is pressed by the convex hull elastic body 38 to trigger to execute the corresponding input function.
On the other hand, when the external force is released, the first supporting plate 22 and the second supporting plate 24, which are correspondingly deformed by the interference of the first supporting plate 30 and the second supporting plate 32 with the second bottom edge 28 and the first bottom edge 26, can provide elastic restoring force to drive the first supporting plate 22 to pivot around the first pivot portion 18 as a fulcrum and the second supporting plate 24 to pivot around the second pivot portion 20 as a fulcrum (meanwhile, the convex elastic body 38 can also provide elastic force to drive the key cap 14 to move upwards), so as to drive the key cap 14 to move from the pressed position shown in fig. 5 and 6 back to the non-pressed position shown in fig. 3 and 4, thereby generating the effect of self-returning.
It should be noted that the design of the bottom edge of the supporting plate is not limited to the above embodiments, for example, please refer to fig. 7, which is a partially enlarged schematic view of a supporting device 16' according to another embodiment of the present invention, wherein the elements in this embodiment and those in the above embodiments have the same numbers, which represent that the elements have the same structures or functions, and the related description thereof is not repeated herein. As shown in fig. 7, the supporting device 16 ' includes a first supporting plate 22 ' and a second supporting plate 24, the first supporting plate 22 ' and the second supporting plate 24 are opposite to each other and respectively have a first bottom edge 26 ' and a second bottom edge 28, a first supporting sheet 30 extends from the first bottom edge 26 ' to the second supporting plate 24 to support under the second bottom edge 28, and a second supporting sheet 32 extends from the second bottom edge 28 to the first supporting plate 22 ' to support under the first bottom edge 26 ' and is offset from the first supporting sheet 30. In this embodiment, the first bottom edge 26 ' may preferably be an outwardly protruding arc (but not limited thereto, other bottom edge shape designs that can reduce the supporting length between the first bottom edge 26 ' and the second supporting sheet 32, such as a convex or wavy bottom edge, etc.), so as to reduce the supporting length between the first bottom edge 26 ' and the second supporting sheet 32, thereby reducing the contact friction between the first bottom edge 26 ' and the second supporting sheet 32, and thus ensuring that the pivoting of the first supporting plate 22 ' and the second supporting plate 24 can be smoother. Similarly, the above bottom edge design can also be applied to the second supporting plate, and the related description can be analogized with reference to the above description, and will not be described herein.
Therefore, under the design that the supporting plate parts are mutually interfered to provide the key resetting force, the configuration of the scissor-leg supporting device and the elastic part can be omitted for the key provided by the invention, so that the space occupied by the whole key is effectively reduced, the subsequent thinning application of a keyboard is facilitated, and the service life of the key is effectively prolonged.
The above detailed description of the preferred embodiments is intended to more clearly illustrate the features and spirit of the present invention, and is not intended to limit the scope of the present invention by the preferred embodiments disclosed above. On the contrary, it is intended to cover various modifications and equivalent arrangements included within the scope of the appended claims. The scope of the invention is therefore to be accorded the broadest interpretation so as to encompass all such modifications and equivalent arrangements as is within the scope of the appended claims.
