Keyboard structure

The invention relates to a keyboard structure.

Modern people often use computers in daily life. Whether it is a desktop computer or a notebook computer, the keyboard is an important role to provide users with character input or operation control. Generally speaking, the keyboard is composed of many keys, and each key is arranged at a specific position. In addition, many electronic devices or motor-operated equipment are also provided with related keys, which are used as operation interfaces for various specified functions.

In terms of current technology, the design of different types of buttons is classified according to their internal switch type, which can be roughly divided into mechanical type, mechanical type, membrane type, conductive rubber type and conductive rubber type. There are several types of contact electrostatic capacity (Capacitive). Different types of button designs are different in terms of service life, pressure experience or production cost.

Generally speaking, the mechanical keyboard has a strong paragraph feel and sound, and is very popular as an operating tool in e-sports activities. However, for notebook computers, this type of mechanical keyboard requires more use conditions in terms of configuration space or operation, and the price is higher, and it is not easy to implement it in notebook computers. Therefore, in order to make the keyboard of the notebook computer also have the operation feeling brought by the mechanical keyboard, and at the same time, it can meet the light and thin structural space required by the notebook computer, which is a problem that relevant technical personnel need to think about and solve.

The invention provides a keyboard structure for optimizing the user's operating situation.

The keyboard structure of the present invention includes a base, a key cap, a scissor-type connection mechanism, and a sound piece. The scissor-type coupling mechanism is movably connected between the keycap and the base, and the scissor-type coupling mechanism has a pressing portion. The click piece is arranged on the scissors-type coupling mechanism and is located on the moving path of the pressing portion. During the pressing process, the keycap is adapted to be pressed and moved closer to the base to change the state of the scissor-type coupling mechanism, and at the same time, the pressing portion presses and deforms the sound piece to make a sound.

Based on the above, the keyboard structure is provided with the corresponding pressing portion and the sound piece in the scissor-type coupling mechanism, and during the pressing process, as the scissors type coupling mechanism changes state, the pressing portion presses and deforms the sound piece , And then make a sound. According to this, the thin and light keyboard structure can be used to stimulate the senses of the user through the generation of the sound during the pressing process, so as to increase the user's operating environment.

In order to make the above-mentioned features and advantages of the present invention more obvious and understandable, the embodiments are specifically described below in conjunction with the accompanying drawings for detailed description as follows.

1 is an exploded view of some components of a keyboard structure according to an embodiment of the invention. 2A is a schematic diagram of some components of the keyboard structure of FIG. 1. 2B is a cross-sectional view of the keyboard structure of FIG. 2A. Please refer to FIG. 1, FIG. 2A and FIG. 2B at the same time. In this embodiment, the keyboard structure 100 includes a base 150, a key cap 140, a scissor-type coupling mechanism 110, and a loudspeaker 120, wherein the scissor-type coupling mechanism 110 is movably connected to the key Between the cap 140 and the base 150. As shown in FIG. 2B, the keyboard structure 100 of this embodiment is a membrane keyboard structure. The base 150 is provided with a membrane switch 151, and an elastic member 130 (rubber dome) is deformably abutted on the base 150 and the key cap 140. Between and surrounded by the scissors-type connection mechanism 110. During the pressing process, the keycap is adapted to be pressed to move closer to the base and deform the elastic member, so that the membrane switch 151 is triggered to achieve the desired pressing effect. Once the keycap 140 is no longer subjected to an urging force and is pressed, the elastic restoring force of the elastic member 130 resets the driving keycap 140 and the scissor-type coupling mechanism 110.

It should be noted that this embodiment only describes the relevant parts of the technology, and the rest of the unrecited ones can already be known from the related technology of the existing membrane keyboard, and will not be described in detail.

It is worth noting that the scissor-type coupling mechanism 110 of this embodiment has a pressing portion 114a, and the sound piece 120 is disposed on the scissor-type coupling mechanism 110 and is located on the moving path of the pressing portion 114a. During the pressing process, As the state of the scissor-type coupling mechanism 110 changes, the pressing portion 114a presses and deforms the sound piece 120 and thus makes the sound piece 120 sound.

FIG. 3A is a schematic diagram of the keyboard structure of FIG. 2A in another state. 3B is a cross-sectional view of the keyboard structure of FIG. 3A. 4A is a schematic diagram of the keyboard structure of FIG. 2A in another state. 4B is a cross-sectional view of the keyboard structure of FIG. 4A. Please refer to FIGS. 2A to 4B at the same time. The sequence from FIG. 2A to FIG. 3A to FIG. 4A (or from FIG. 2B to FIG. 3B to FIG. 4B in sequence) can represent the process of pressing the keyboard structure 100.

In detail, the scissor-type coupling mechanism 110 includes a first frame 112 and a second frame 114, wherein one side of the first frame 112 is pivotally connected to the key cap 140 along an axis by a pivot structure, The other side is also pivotally connected to the base 150 along the axial direction by its pivot structure. Similarly, one side of the second frame 114 is also pivotally connected to the base 150 along the axial direction by its pivot structure, and the other side of the second frame 114 abuts the keyboard 140. According to this, during the pressing process, the key cap 140 is pressed and can smoothly move up and down relative to the base 150 by the first frame 112 and the second frame 114.

Furthermore, the second frame 114 is provided with a pressing portion 114a on its side arm 114b, and the sound piece 120 has a holding portion 122 and an extending portion 124. The holding portion 122 is disposed on the side arm 112a and the extending portion 124 of the first frame 112 When extending from the holding portion 122 toward the keycap 140, the extending portion 124 and the side arm 112a maintain a gap 121, and as the extending portion 124 (from bottom to top) moves away from the holding portion 122, the gap 121 is gradually expanding.

Based on the above, since the moving paths of the extending portion 124 and the pressing portion 114a intersect each other, and during the pressing process, the extending direction of the extending portion 124 is opposite to the moving direction of the pressing portion 114a, so during the pressing process, the pressing portion The portion 114 a will press the extension portion 124 to deform the extension portion 124 relative to the holding portion 122 and thus change the size of the gap 121. As shown in FIGS. 3B and 4B, the pressing portion 114a on the same side of the scissor-type coupling mechanism 110 and the extending portion 124 of the sound piece 120 interfere with each other during the pressing process, and as shown in partial enlargement in FIG. 4B, the extending The portion 124 is driven by the pressing portion 114a to generate a lateral displacement d1 (the dotted outline shown in FIG. 4B represents the extended portion 124 at the position shown in FIG. 3B), which also means that the gap 121 will shrink due to the deformation of the sound piece 120. In other words, the sound piece 120 is essentially a metal shrapnel structure, which can generate sound due to deformation by force, and restores its original shape according to its elasticity when not stressed. Accordingly, by disposing the pressing portion 114a and the loudspeaker 120 on different parts of the scissor-type coupling mechanism 110 (ie, the first frame 112 and the second frame 114), and allowing the two to meet during the pressing process, The sound piece 120 can be smoothly deformed by the pressing portion 114a to generate sound. In this way, the sound emitted by the sound piece 120 can provide sensory stimulation to the user during the pressing action, thereby enhancing the user's usage situation.

It should be further noted that, since the first frame 112 and the second frame 114 of the scissor-type coupling mechanism 110 are cross-connecting mechanisms with each other, although the above embodiment only uses the loudspeaker 120 on the first frame 112 to allow the second frame 114 has a pressing portion 114a as an example, but does not limit the present invention. In another embodiment not shown, the loudspeaker can be arranged in the first frame, and the second frame has a pressing portion, that is to say, the pressing portion and the extending portion of the loudspeaker can be pressed during the pressing process Those who can interfere with each other and cause the sound piece to deform will also make the sound piece sound and achieve the same effect as the above embodiment.

In summary, in the above-mentioned embodiment of the present invention, the keyboard structure is provided with different pressing parts and loudspeakers corresponding to each other on the different parts of the scissor-type coupling mechanism. During the pressing process, due to the pressing parts and The extensions of the loudspeaker can meet each other, so the loudspeaker can be smoothly deformed by being driven by the pressing part, that is, as the scissors-type coupling mechanism changes state, the pressing part can make the loudspeaker deform by pressing and deforming the loudspeaker The sound of the movie was able to make a sound. In this way, the keyboard structure can produce a sound during the pressing process while maintaining its thin and light structure and limited actuation stroke, thereby stimulating the user's senses to improve the user's operating situation, and with The mechanical keyboard has the same effect.

Although the present invention has been disclosed as above with examples, it is not intended to limit the present invention. Any person with ordinary knowledge in the technical field can make some changes and modifications without departing from the spirit and scope of the present invention. The scope of protection of the present invention shall be subject to the scope defined in the appended patent application.
