Description

Key structure improvement

This creation is related to a pressing element, especially a button structure improvement that reduces knocking noise.

Pressing, for example, the keys on the keyboard generally include a substrate, a keycap, and a scissor structure that is movably coupled between the substrate and the keycap, and is generally referred to as a blank key, a Shift key, an Enter key, etc. on the keyboard. "Multiple keys", because the width of the key cap itself is wider than the width of the general "double key", when the pressure is unbalanced, it is easy to cause the keycap to be less incompletely displaced, so that the key cap cannot be made. Provide a more complete compression stroke, so it is often necessary to add a so-called "balance bar" to maintain its balance.

However, since the conventional push button is added with the balance bar, it is easy to generate noise when the strike bar collides with the substrate of the keyboard when striking, which causes inconvenience to the user.

In view of this, the creator is trying to improve and solve the above-mentioned shortcomings, and he has devoted himself to researching and cooperating with the application of theory, and finally proposed a creation that is reasonable in design and effective in improving the above-mentioned defects.

The main purpose of the present invention is to provide a button structure improvement, which is provided with a reinforcing member for replacing the traditional balance bar on the scissors structure of the button, so as to maintain the strength of the scissors structure by the position of the reinforcing member to ensure the button The balance of the press is also able to avoid noise.

In order to achieve the above object, the present invention provides a button structure improvement, comprising a substrate, a keycap, and a scissors assembly, the key cap is disposed on the substrate, and the scissors assembly has two link members interdigitated and pivoted, and the scissors The component is connected between the substrate and the keycap; wherein a reinforcing member is horizontally disposed at an end of each of the connecting rod members connected to the keycap.取代 Replacing the traditional balance bar with a reinforcing member while reducing the noise generated when the key cap is struck.

In order to further disclose the features and technical contents of the present invention, please refer to the following detailed description and drawings of the present invention. However, the drawings are only for reference and description, and are not intended to limit the creation.

Please refer to FIG. 1 , FIG. 2 and FIG. 3 , which are respectively an exploded perspective view, a three-dimensional combination diagram and a combined sectional view of the creation. The present invention provides a button structure improvement, comprising a substrate 1, a keycap 2, and a scissors assembly 3; wherein:

The substrate 1 is used to carry the components such as the key cap 2 and the scissors assembly 3, and may be laminated on each other by a metal plate (hard plate) and a circuit layer, and is provided with a lower connecting portion 10 connected to the scissors assembly 3, and connected below. The portion 10 includes, for example, two pivoting members and two limiting members.

The key cap 2 is used for pressing by a human hand, and can be a key cap of a double key, or a multiple key such as a blank key, a Shift key, an Enter key, a caps lock key, a backspace key, a tab key, an alter key, etc. on a keyboard. The key cap is connected to the base plate 1 via the scissors assembly 3, and the upper cover portion 20 is connected to the scissor assembly 3, and the upper connecting portion 20 includes, for example, two pivoting members and two Limiter.

The scissors assembly 3 is connected between the substrate 1 and the keycap 2 to drive the keycap 2 to reciprocate up and down on the substrate 1, thereby enabling the human hand to strike the keycap 2 to achieve the purpose of inputting the key command. The scissors assembly 3 has a two-link member 30 connected between the substrate 1 and the keycap 2. In the present embodiment, the two link members 30 are mutually pivotally connected and one of the two link members 30 is framed to surround the other of the two link members 30. Each of the link members 30 may have a first connecting portion 300 connected to the lower connecting portion 10 of the substrate 1 and a second connecting portion 301 connected to the connecting portion 20 above the key cap 2. For example, the second connecting portion 301 is located at one end of each link member 30 and is pivotally or slidably connected to the upper connecting portion 20 of the keycap 2, and the first connecting portion 300 is located at each connecting rod member. The other end of the 30 is pivotally or slidably connected to the lower connecting portion 10 of the substrate 1, wherein one end of each link member 30 is opposite to the other end, and when the key cap 2 is not pressed, the other end One end is farther away from the keycap 2 than the one end. Furthermore, the scissors assembly 3 can be provided with a through hole 302 in one of the link members 30 for further providing an elastic body 31 between the substrate 1 and the keycap 2, and the scissors assembly 3 can be provided to push the keycap 2 for the upper and lower reciprocating motion.

As shown in FIG. 4 , the present invention mainly applies a reinforcing member 4 to the end edge 303 of the connecting rod assembly 3 at one end of the connecting rod assembly 3 and the key cap 2 to pass through the reinforcing member 4 . It replaces the traditional balance bar to avoid the noise caused by the traditional balance bar during tapping. Specifically, in the embodiment shown in the drawing, the reinforcing member 4 is provided at the edge of one end of each of the link members 30. Further, the reinforcing member 4 is provided at the outer side of the end edge 303 of the link member 30 and covers the surface of the end edge 303 of the connecting member 30. Therefore, the reinforcing member 4 as a whole can be exposed. In the present embodiment, the reinforcing member 4 may be made of metal or other steel material and joined to the outer surface of the end edge 303 of the link member 30 in a sheet shape. In this embodiment, the end edge 303 of the link member 30 may be provided with a plurality of bumps 304. The reinforcing member 4 may be provided with a corresponding plurality of riveting holes 40, and by, for example, riveting or mutually engaging the bumps 304. The reinforcing member 4 is coupled to the end edge 303 of the link member 30 in a manner similar to the rivet hole 40. In other embodiments, the reinforcing member 4 can be integrally wrapped and projected on the end edge 303 of the link member 30 when the link member 30 is formed of a plastic material.

Since the present invention replaces the conventional balance bar with the reinforcing member 4 provided on the end edge 303 of the link member 30, the key cap 2 does not have the noise caused by the previous balance bar striking the substrate 1 when struck, and at the same time reinforces Since the member 4 is disposed on the end edge 303 of the link member 30, especially at the outer side of the end edge 303, the keycap 2 does not cause the reinforcing member 4 to sound due to impact on the substrate 1 when struck, thereby reducing The noise generated during the tapping can still maintain the balance of the keycap 2 when it is actuated.

Therefore, the structure of the present button can be improved by the above-described structural composition.

In addition, as shown in FIG. 5, it is a schematic cross-sectional view of another embodiment of the original reinforcing member 4; wherein the cross-section of the reinforcing member 4 can also be an "L" shape, that is, having a coating on the connecting rod. The outer side portion 41 of the outer side surface of the end edge 303 of the member 30, and an upper side portion 42 covering the upper surface of the end edge 303 of the connector member 30. Moreover, as shown in FIG. 6 , it is an exploded view of another embodiment of the creative link member 30 and the reinforcing member 4; wherein the reinforcing member 4 further has a plurality of lower side portions 43 disposed at intervals to be relatively covered The lower edge of the end edge 303 of the connector 30. The lower side portion 43 can prevent the sound from striking the substrate 1 when the keycap 2 is struck, and can further increase the strength of the scissors assembly 3, based on the manner in which it is spaced apart.

In summary, this creation is a rare new creative product, which can achieve the intended use, but solve the lack of knowledge, and because of its novelty and progress, it fully meets the requirements of new patent applications.
