Abstract
The invention discloses a key, which comprises a base, an upper cover, a key cap, a sleeve part and a sounding part. The upper cover is arranged on the base and provided with a side slotted hole. The key cap extends to the base to form a connecting column, and the convex rib protrudes outwards from the connecting column to form. The sleeve member is movably arranged in the base and penetrates out of the upper cover to be detachably connected to the connecting column. The sounding piece is arranged outside the base and provided with a flexible rod part so as to be positioned below the convex rib. When the key cap drives the sleeve member to move downwards to enable the convex rib to move downwards along the side slotted hole, and the flexible rod portion is not enough to enable the flexible rod portion to pass over the convex rib due to the bending deformation generated by the fact that the convex rib is pressed by the flexible rod portion, the flexible rod portion bends downwards along with the convex rib. When the flexible rod portion is sufficiently deformed to allow the flexible rod portion to pass over the rib, the flexible rod portion is released and moves upward to strike the upper cover to make a sound. The invention can solve the problem of complex assembly flow in the prior art.

Background
In the current usage practice of personal computers, a keyboard is one of the indispensable input devices for inputting characters, symbols or numbers. Moreover, in order to operate consumer electronic products in daily life or large processing equipment used in industry, a key structure is required to be provided as an input device for operating the electronic products and the processing equipment.
In practical applications, in order to provide different key pressing handfeel (tactile feedback) for users, a key switch with different specifications must be designed for users to purchase; for example: the electronic competition keyboard can indicate that the used key switches are red shafts, brown shafts, black shafts or other color shafts on the packaging box; the method for informing the user of the pressing hand feeling of the keyboard key by using different colors can comprise: the connection position between the trigger spring arm and the trigger contact is high or low, a key press stroke (travel distance), a press section sense (tap or linear), a press sound feedback (click or non-click), and the like.
In terms of pressing sound feedback and pressing paragraph sense design, it is generally required to additionally add a sounding elastic member at a position in the key switch, which can be in interference fit with a rib on the sleeve member of the key, so that when a user presses the key downwards, the sounding elastic member can be pressed down by the rib in the pressing process to deform flexibly, and then pass over the rib to generate paragraph sense or further strike the internal components of the key switch to generate sound. However, the above design of adding the sounding elastic member to the inside of the key switch often results in time-consuming and labor-consuming key manufacturing and assembling processes, and also causes unnecessary design restrictions on the internal configuration of the key switch.

Detailed Description
The following description of the embodiments refers to the accompanying drawings, which illustrate specific embodiments in which the invention may be practiced. The terms of directions used in the present invention, such as "up", "down", "front", "back", "left", "right", "side", etc., refer only to the directions of the attached drawings. Accordingly, directional terminology is used to describe and understand the invention and is not limiting of the invention.
In the following embodiments, like parts are denoted by like reference numerals in different drawings.
Referring to fig. 1 and 2, fig. 1 is a schematic exploded view of a portion of a key 10 according to an embodiment of the present invention, and fig. 2 is an enlarged schematic view of a key cap 16 of fig. 1 from another perspective, as shown in fig. 1 and 2, the key 10 includes a base 12, a top cover 14, a key cap 16, a sleeve member 18 and a sounding member 20. The upper cover 14 is disposed on the base 12 and the upper cover 14 has side slotted holes 22. The key cap 16 is formed with a connecting post 24 extending toward the base 12, and a rib 26 is formed to protrude outward from a position of the connecting post 24 corresponding to the side slotted hole 22. The sleeve member 18 is movably disposed through the base 12 and the sleeve member 18 extends out of the upper cover 14 to be detachably connected to the connecting post 24 of the key cap 16, so that the key cap 16 can move up and down between a higher position (or referred to as a release position, hereinafter the same) and a lower position (or referred to as a pressing position, hereinafter the same). The sounding member 20 is disposed outside the base 12, and the sounding member 20 has a flexible rod portion 28, and when the keycap 16 is in the release position, the flexible rod portion 28 is located below the rib 26, in more detail, in this embodiment, the upper cover 14 may have a post 30, and the upper cover 14 protrudes outwards to form a stop block 32, and the sounding member 20 may further have a spring portion 34, where the flexible rod portion 28 extends from the spring portion 34 to the stop block 32, and the spring portion 34 is sleeved on the post 30 and the stop block 32 pre-presses the flexible rod portion 28.
In practical applications, in order to enhance the convenience of assembly, the sleeve member 18 may preferably extend toward the connecting post 24 to form a protruding shaft 19 (preferably, but not limited to, cross-shaped), and the connecting post 24 may have a recess 25 at a position corresponding to the protruding shaft 19, such that the protruding shaft 19 may be inserted into the recess 25 to detachably connect the key cap 16 to the sleeve member 18. In addition, the key 10 may further include an elastic member 36, and the elastic member 36 may preferably be a spring (but is not limited thereto), and the elastic member 36 is disposed between the sleeve member 18 and the base 12, so that when the key cap 16 is not pressed by an external force, the elastic member 36 drives the key cap 16 to return to the higher position via the sleeve member 18, thereby generating the effect that the key cap 16 can return automatically, so that the user can perform the subsequent key cap pressing operation.
With the above design, after the key cap 16 is connected to the sleeve member 18, the key 10 provides a pressing feeling with a feel of a bump and a pressing sound during the pressing of the key cap 16 by a user, and more particularly, referring to fig. 3, 4 and 5, fig. 3 is a front view of the key 10 of fig. 1 when the key cap 16 is assembled to the sleeve member 18, fig. 4 is a front view of the rib 26 of fig. 3 bending downward by pressing the flexible rod 28 with the downward movement of the key cap 16, and fig. 5 is a front view of the key 10 of fig. 4 when the key cap 16 is pressed to a lower position, wherein the key cap 16 is schematically shown by a dotted line in fig. 3 to 5 for clearly showing the structural actuation relationship between the flexible rod 28 and the rib 26. When the key cap 16 is in the upper position as shown in fig. 3 (at this time, the rib 26 is located above the flexible rod portion 28) and the key cap 16 receives an external force to drive the sleeve member 18 to move downward and move the rib 26 downward along the side slot hole 22, the flexible rod portion 28 correspondingly passes over the rib 26 during the downward movement of the key cap 16.
In the above process, when the key cap 16 moves downward and the flexible rod 28 is not sufficiently deflected by the abutment of the rib 26 to cause the flexible rod 28 to pass over the rib 26, the flexible rod 28 deflects downward with the rib 26 and away from the stop 32 (as shown in fig. 4). Then, the key cap 16 continues to move downward, and when the upward restoring force generated by the deflection of the flexible rod 28 increases enough to cause the flexible rod 28 to pass over the rib 26, the flexible rod 28 can be correspondingly released because the deflected flexible rod 28 is no longer pressed down by the rib 26, and further moves upward to the position shown in fig. 5 and impacts the stop block 32 of the upper cover 14 to make a sound, so that the key 10 can provide a feeling of jerk generated when the rib 26 presses the flexible rod 28 to deflect and then the flexible rod 28 is released and a pressing feel of a pressing sound when the flexible rod 28 impacts the stop block 32 of the upper cover 14. Finally, when the key cap 16 is moved to the lower position as shown in fig. 5, the sleeve member 18 can perform the switch triggering operation of the key 10 (the related description of the key switch triggering design and principle is common in the prior art, and will not be described herein), so that the key 10 can perform the function desired by the user.
Therefore, the invention adopts the configuration that the sounding piece is directly arranged outside the base without additionally arranging the sounding piece inside the key switch, so that the invention not only can effectively solve the problem of time-consuming and labor-consuming key manufacturing and assembling processes caused by additionally arranging the sounding elastic piece inside the key switch in the prior art, but also can improve the component arrangement elasticity of the key on the internal space between the upper cover and the base, thereby being beneficial to the thinned design of the key.
It should be noted that, since the key cap 16 is detachably connected to the sleeve member 18, the key 10 allows the user to adjust the pressing feeling of the key 10 by replacing the key cap, for example, when the user wants to switch the key 10 to a pressing feeling that can provide no feeling of frustration and no pressing sound during the pressing of the key cap by the user, the user only needs to detach the key cap 16 from the sleeve member 18 by using an adjusting jig or a pliers hand tool, and then assemble a conventional standard key cap without the rib 26 to the sleeve member 18, so that the pressing feeling without frustration and no pressing sound is provided by the key 10 because the flexible rod 28 is not pressed by the rib 26 during the pressing of the replaced key cap by the user and then passes over the rib 26 to strike the stop block 32.
In addition, the structural design of the sounding member is not limited to the above embodiment, for example, please refer to fig. 6, which is a front view of a key 10 'according to another embodiment of the present invention, wherein the key cap 16 is schematically shown in fig. 6 with a dotted line for clearly showing the structural design and configuration of the sounding member 20', and the components in this embodiment and the components in the above embodiment have the same numbers, which means that they have the same structure or function, and their related descriptions are not repeated herein. As can be seen from fig. 6, the key 10 'includes a base 12, an upper cover 14, a keycap 16, a sleeve member 18 and a sounding member 20', the sounding member 20 'is disposed outside the base 12, the sounding member 20' may have a flexible rod portion 28 and a torsion spring portion 38, the flexible rod portion 28 may extend from the torsion spring portion 38 to the stop block 32, the torsion spring portion 38 may be connected to the upper cover 14 (for example, the torsion spring portion 38 is sleeved on a lateral bump of the upper cover 14 and one end of the torsion spring portion 38 is abutted against a bottom edge of the upper cover 14 (as shown in fig. 6), but the present invention is not limited thereto). As for other related descriptions of the key 10' (e.g. connection design between the key cap and the sleeve member, structural actuation relationship between the rib and the flexible shaft portion, configuration of the elastic member, etc.), reference should be made to the above-mentioned embodiments, and the description thereof will be omitted.
It should be noted that the configuration of the ribs is not limited to the above embodiment, for example, please refer to fig. 7, 8, 9 and 10, fig. 7 is a partially exploded schematic view of the key 100 according to another embodiment of the present invention, fig. 8 is a front view of the rib 106 of fig. 7 above the flexible rod portion 28, fig. 9 is a front view of the rib 106 of fig. 8 for depressing the flexible rod portion 28 for bending deformation, fig. 10 is a front view of the flexible rod portion 28 of fig. 9 for releasing the rib 106, wherein the structural relationship between the flexible rod portion 28 and the rib 106 is omitted from fig. 8 to 10, and the components of this embodiment and the components of the above embodiment have the same numerals, which represent the same structure or function, and their related descriptions will not be repeated herein. As can be seen from fig. 7 to 10, the key 100 includes a base 12, an upper cover 14, a key cap 102, a sleeve member 104 and a sounding member 20, in this embodiment, the key cap 102 extends toward the base 12 to form a connecting post 24, a rib 106 protrudes from a position of a slot 22 on a corresponding side of the sleeve member 104, the sleeve member 104 preferably extends toward the connecting post 24 to form a protruding shaft 19 (preferably, but not limited to, a cross shape), and the connecting post 24 may have a groove 25 corresponding to the protruding shaft 19, whereby the protruding shaft 19 of the sleeve member 104 may be inserted into the groove 25 of the key cap 102 to detachably connect the key cap 102 to the sleeve member 104.
With the above design, after the key cap 102 is connected to the sleeve member 104, the key 100 provides a pressing feeling with a feeling of a bump and a pressing sound during the pressing of the key cap 102 by the user, more specifically, as shown in fig. 7 to 10, when the sleeve member 104 moves downward along with the key cap 102 and the rib 106 moves downward along the side slot hole 22, the flexible rod portion 28 correspondingly passes over the rib 106 during the downward movement of the sleeve member 104.
In the above process, when the deflection of the flexible rod 28 due to the abutment of the rib 106 is insufficient to cause the flexible rod 28 to pass over the rib 106, the flexible rod 28 deflects downward with the rib 106 and away from the stop block 32 (as shown in fig. 9). Then, when the flexible lever 28 is deflected sufficiently to allow the flexible lever 28 to pass over the rib 106, the flexible lever 28 is correspondingly released and then moves upward back to the position shown in fig. 10 and impacts the stop 32 of the upper cover 14, thereby making a sound, such that the key 100 provides a clicking feel as the rib 106 presses down on the flexible lever 28 and then releases the flexible lever 28 and a pressing feel as the flexible lever 28 impacts the stop 32 of the upper cover 14.
In this way, by the design that the ribs 106 are directly formed on the sleeve member 104, the key 100 allows the user to adjust the pressing feeling of the key 100 by directly replacing the key switch (i.e. the pressing switch device formed by the upper cover, the sleeve member and the base together), for example, when the user wants to switch the key 100 to a pressing feeling that can provide no feeling of a bump and no pressing sound during the process of pressing the key cap by the user, the user only needs to detach the key cap 102 from the sleeve member 104 by using an adjusting tool or a pliers hand tool, and then replace the pressing switch device comprising the sleeve member 104 with the ribs 106 with the pressing switch device without the ribs 106 and the sounding member 20, thereby the key 100 can provide a pressing feeling that can provide no feeling of a bump and no pressing sound. As for other related descriptions (such as the configuration of the elastic element, the design of the sounding element, etc.) of the key 100, reference may be made to the above-mentioned embodiments, and thus, the description thereof will not be repeated.
The invention adopts the configuration that the sounding piece is directly arranged outside the base without additionally arranging the sounding piece in the key switch, thus the invention not only can effectively solve the problem of time and labor consuming key manufacturing and assembling flow caused by additionally arranging the sounding elastic piece in the key switch in the prior art, but also can improve the component configuration elasticity of the key on the application of the inner space between the upper cover and the base so as to be beneficial to the thinned design of the key.
The above detailed description of the preferred embodiments is intended to more clearly describe the features and spirit of the present invention, but is not intended to limit the scope of the present invention by the above disclosed preferred embodiments. On the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the scope of the invention as defined by the appended claims. The scope of the invention is therefore to be construed in its broadest sense in view of the foregoing description and is instead intended to cover all possible modifications and equivalent arrangements.
