Abstract
The invention discloses a keyboard which comprises a substrate, a hook structure and a plastic connecting piece. The substrate has a top surface. The clamping hook structure is connected with the substrate and stands up relative to the top surface. The plastic connecting piece is positioned on the top surface and is clamped with at least one part of the clamping hook structure.
Description
Technical Field
The present invention relates to a keyboard.
Background
In order to balance the force applied by the user on each key of the keyboard, a guiding connection structure is usually disposed under the key cap of the key to guide the key cap to move vertically. Therefore, no matter the force is applied to the side edge or the corner of the keycap, the force can be evenly dispersed on the whole keycap surface, so that the whole key is easy to press, and the user can operate the key more easily.
Generally, the guiding connection structure is usually fixed in the keyboard by engaging with a hook formed on the bottom plate. One conventional manufacturing method of the base plate with the hooks is to perform a stamping process on a sheet metal part to stamp out the hooks that can be bent and erected. However, when the guide connecting structure is engaged with the hook, the engaging portion of the guide connecting structure is limited between the hook and the bottom plate, so that the machining precision when the hook is bent may greatly affect the assembly tolerance between the guide connecting structure and the hook, and often cause the problems of key shaking and tilting. Moreover, the bottom plate and the guiding connection structure are generally made of metal, so that when the keyboard is used, metal knocking noise is often generated.
In addition, under the trend of light weight and thin keyboard, the structure of the existing guiding connection structure and metal bottom board is not able to meet the requirement. For example, if the above-mentioned structure is designed to reduce the thickness of the metal base plate to meet the requirement of weight reduction, the strength of the metal base plate is reduced, which results in that the metal base plate cannot be subjected to processing processes such as stamping and bending, and even if the metal base plate is subjected to the processing processes, the mechanical strength cannot be taken into consideration.
Therefore, how to provide a keyboard capable of solving the above problems is one of the problems that the industry needs to invest in research and development resources to solve.
Disclosure of Invention
In view of the above, the present invention is directed to a keyboard that can effectively solve the above problems.
To achieve the above objective, according to one embodiment of the present invention, a keyboard comprises a substrate, a hook structure and a plastic link. The substrate has a top surface. The clamping hook structure is connected with the substrate and stands up relative to the top surface. The plastic connecting piece is positioned on the top surface and is clamped with at least one part of the clamping hook structure.
In one or more embodiments of the present invention, the substrate has a through hole penetrating the top surface. The hook structure is adjacent to the through hole.
In one or more embodiments of the invention, the plastic link extends partially into the through-hole.
In one or more embodiments of the invention, the plastic link is located completely outside the through hole.
In one or more embodiments of the present invention, the keyboard further includes another hook structure. The other hook structure is connected with the substrate and stands up relative to the top surface. The plastic connecting piece is also fixed with the other clamping hook structure.
In one or more embodiments of the present invention, the other hook structure is adjacent to the through hole. The hook structure and the other hook structure are respectively positioned at two sides of the through hole.
In one or more embodiments of the present invention, the substrate further has another through hole penetrating the top surface. The other hook structure is adjacent to the other through hole.
In one or more embodiments of the present invention, the substrate further has ribs. The rib separates the through hole from the other through hole and supports the plastic joint member.
In one or more embodiments of the invention, the hook structure is embedded in the plastic engagement member.
In one or more embodiments of the present invention, the hook structure has a surface. The surface has stop portions facing substantially toward the substrate. A portion of the plastic engaging member is located between the stop portion and the top surface.
In one or more embodiments of the present invention, a normal of the stopper portion passes through the top surface of the substrate and a virtual extension surface of the top surface.
In one or more embodiments of the present invention, the substrate and the hook structure are connected to each other by a single structure.
In one or more embodiments of the present invention, the top surface is flat.
In summary, the keyboard of the present invention utilizes the plastic connecting element disposed on the substrate to connect with the guiding connection structure, instead of the conventional keyboard, which utilizes the hook on the metal bottom plate to connect with the guiding connection structure. The plastic connecting piece arranged on the substrate can increase the structural strength of the substrate, thereby effectively avoiding the problem of substrate deformation caused by compression when the guide connecting structure is assembled or the keycap is pressed, and further thinning the substrate to realize the purposes of light weight and thinning. Moreover, the assembly tolerance between the plastic connecting piece and the guiding connecting structure can be controlled by the manufacturing precision of the plastic connecting piece, and the keyboard can not be influenced by the processing precision when the existing keyboard is bent and clamped, so the assembly precision of the keyboard can be improved.
The foregoing is merely illustrative of the problems to be solved, solutions to problems, and effects produced by the present invention, and specific details thereof are set forth in the following description and the accompanying drawings.

Detailed Description
In the following description, for purposes of explanation, numerous implementation details are set forth in order to provide a thorough understanding of the various embodiments of the invention. It should be understood, however, that these implementation details are not to be interpreted as limiting the invention. That is, in some embodiments of the invention, such implementation details are not necessary. In addition, for the sake of simplicity, certain conventional structures and components are shown in simplified schematic form in the drawings, and the same components in different embodiments are labeled with the same reference numerals.
Please refer to fig. 1 and fig. 2. Fig. 1 is a perspective view illustrating a keyboard 100 according to an embodiment of the invention. Fig. 2 is a partially exploded view of the keyboard 100 according to an embodiment of the invention. As shown in fig. 1 to fig. 2, the keyboard 100 of the present embodiment may be an external keyboard (e.g., a PS2 interface keyboard or a USB interface keyboard) for a desktop computer or an input device including keys (e.g., a touch pad on a notebook computer), but is not limited thereto. In other words, the concept of the keyboard 100 of the present invention can be applied to any electronic product using pressing as an input method. In the present embodiment, the keyboard 100 includes a substrate 110, a plurality of hook structures 120 (only one is representatively shown), a plurality of plastic links 130 (only one is representatively shown), and a plurality of key assemblies 140 (only one is representatively shown), wherein the combination of the substrate 110, the four pairs of hook structures 120, the four plastic links 130, and the key assembly 140 can be regarded as a single key device. The structure and function of each component included in the keyboard 100 and the connection relationship between each component will be described in detail below.
Please refer to fig. 3A and fig. 3B simultaneously. Fig. 3A is a perspective view illustrating a portion of the substrate 110, the hook structures 120 and the plastic connectors 130 according to an embodiment of the invention. Fig. 3B is an exploded view showing the structure in fig. 3A. As shown in fig. 2 to 3B, in the present embodiment, the substrate 110 has a top surface 111. The hook structure 120 is connected to the substrate 110 and stands up with respect to the top surface 111 of the substrate 110. The plastic engagement member 130 is located on the top surface 111 and engages at least a portion of the hook structure 120. For example, the plastic connecting element 130 is formed on the hook structure 120 by, for example, an injection molding process, so that the plastic connecting element 130 abuts against the hook structure 120, and the plastic connecting element 130 is engaged with at least a portion of the hook structure 120, so that the two are firmly combined. The plastic engaging member 130 is retained by the hook structure 120 and is fixedly disposed on the substrate 110. Further, the plastic connecting member 130 may have at least one groove portion 132, at least one portion of the hook structure 120 is disposed in the groove portion 132, the shape of the groove portion 132 corresponds to the shape of at least one portion of the hook structure 120 (for example, the surfaces abutting against each other are complementary or conformal), so that at least one portion of the hook structure 120 is engaged with the plastic connecting member 130, and at least one portion of the hook structure 120 is surrounded and covered by the plastic connecting member 130. The key assembly 140 includes a guiding connection structure 141 and a key cap 142. The keycap 142 is positioned over the substrate 110. The guiding connection structure 141 is connected between the plastic connector 130 and the key cap 142. The guiding connection structure 141 is configured to guide the keycap 142 to move up and down toward and away from the substrate 110.
With the above structure configuration, the conventional keyboard 100 can be replaced by connecting the hooks on the metal base plate with the guiding connection structure 141. Specifically, in the present embodiment, the plastic connecting element 130 disposed on the substrate 110 can increase the structural strength of the substrate 110, so that the problem of deformation of the substrate 110 or the hook structure 120 caused by pressing when the guiding connection structure 141 is assembled or the key cap 142 is pressed can be effectively avoided, thereby allowing the substrate 110 to be further thinned, and achieving the purpose of light weight and thinning of the keyboard 100. Moreover, the assembly tolerance between the plastic connecting element 130 and the guiding connection structure 141 can be controlled by the manufacturing precision of the plastic connecting element 130 itself, and is not affected by the processing precision when the conventional keyboard 100 is bent and hooked, so that the assembly precision of the keyboard 100 of the present embodiment can be improved.
In the embodiment shown in fig. 2, the guiding connection structure 141 is formed by two connecting rods pivotally connected to each other, but the invention is not limited thereto. In practical applications, the guiding connection structure 141 can be replaced by other connection structures with similar functions (i.e. driving the key cap 142 to move up and down relative to the substrate 110), such as a V-shaped, a-shaped or two parallel link structures.
In some embodiments, the keyboard 100 may further comprise a circuit board (not shown). The circuit board may be disposed between the substrate 110 and the key assembly 140, and a key circuit is disposed thereon, so as to generate a corresponding key signal when the key cap 142 of the key assembly 140 is triggered. In some embodiments, the circuit board may be a rigid printed circuit board or a flexible circuit board, but the invention is not limited thereto.
In some embodiments, the key assembly 140 may further include a reset member (not shown). The reset element may be disposed on the substrate 110, between the substrate 110 and the key cap 142, and above the key circuit. When the key cap 142 is pressed down by external force, the reset piece will generate a resistance force to the key cap 142, thereby providing the hand feeling of pressing by the user. The restoring member may provide a restoring force to return the depressed key cap 142 to the original, non-depressed position after the external force applied to the key cap 142 is released. In some embodiments, the restoring member may be an elastic member, such as a rubber dome, a metal dome, or a spring sheet. In other embodiments, the reset element may be other elements with similar functions, such as a magnetic element.
As shown in fig. 3A and 3B, in the present embodiment, the substrate 110 has a through hole 112 penetrating the top surface 111. The hook structure 120 is adjacent to the through hole 112. Specifically, the hook structure 120 is bent from the inner wall of the through hole 112 toward one side of the top surface 111 of the substrate 110. In some embodiments, the substrate 110 and any of the hook structures 120 are connected together as a single structure. For example, a metal plate may be punched by a punching process to simultaneously fabricate the substrate 110 having the through hole 112 and the hook structure 120 extending in the through hole 112. Then, the hook structure 120 is bent toward one side of the top surface 111 of the substrate 110 by a bending process, so that the hook structure 120 can stand up relative to the top surface 111 of the substrate 110.
In the embodiment shown in fig. 3A and 3B, the hook structure 120 is embedded in the plastic link 130 from one side of the plastic link 130. For example, when the plastic link 130 is formed on the hook structure 120 by an injection molding process, the side surface of the plastic link 130 only covers at least a portion of the hook structure 120. The hook structure 120 has a surface. The surface has a stop portion 121. The stopper portion 121 substantially faces the substrate 110. The specific definition of "substantially facing" as used herein refers to, for example, a normal N (see fig. 4) of the stopper portion 121 passing through the top surface 111 of the substrate 110 and a virtual extension plane V of the top surface 111 (i.e., the normal N passing through the through hole 112 also meets the definition). A portion of the plastic link 130 is located between the stop portion 121 and the top surface 111. Therefore, as long as the plastic connecting element 130 has the stopping portion 121 covering the hook structure 120, the stopping portion 121 can prevent the portion of the plastic connecting element 130 between the stopping portion 121 and the top surface 111 from moving away from the top surface 111, so as to prevent the plastic connecting element 130 from being pulled out from the hook structure 120 in a direction away from the substrate 110. In addition, since the plastic connecting element 130 is mainly fixed to the hook structure 120, the top surface 111 of the substrate 110 can be kept flat.
In the embodiment shown in fig. 3A and 3B, two hook structures 120 are adjacent to the through hole 112 and located on two sides of the through hole 112. For example, two hook structures 120 are respectively located at two opposite corners of the through hole 112. And, the plastic engaging member 130 is fixed to the two hook structures 120 at the same time. Therefore, the plastic connecting element 130 can be more firmly fixed on the substrate 110 and can have a stronger pulling resistance, but the invention is not limited thereto. In practical applications, only one hook structure 120 may be adjacent to the through hole 112 and fixed to the plastic connecting element 130, and the purpose of fixing the plastic connecting element 130 to the substrate 110 can still be achieved. In some embodiments, the two hook structures 120 adjacent to the through hole 112 can be located on the same side of the through hole 112, and the plastic connecting member 130 is fixed to the two hook structures 120 at the same time, so as to fix the plastic connecting member 130 to the substrate 110.
In some embodiments, the hook structure 120 may also extend from a bottom surface of the plastic link 130 to be embedded in the plastic link 130, thereby increasing the fixing strength between the hook structure 120 and the plastic link 130.
In the embodiment shown in fig. 3A and 3B, the plastic link 130 has a link 131. The connection portion 131 has a shape of a water drop hole and is configured to be pivotally connected to the rotation shaft of the guide connection structure 141, but the invention is not limited thereto. In some embodiments, the engaging portion 131 of the plastic engaging member 130 may also have a shape of a sliding slot and is configured to slidably engage with a sliding shaft of the guiding connection structure 141.
Referring to FIG. 4, a cross-sectional view of the structure of FIG. 3A along line 4-4 is shown. As shown in fig. 4, in this embodiment, the plastic link 130 extends partially into the through-hole 112. In the embodiment shown in fig. 4, although the plastic connector 130 completely fills the through hole 112, in practical applications, the plastic connector 130 may only partially fill one or more specific locations (e.g., one or more edges or corners) within the through hole 112.
Fig. 5 is a perspective view illustrating a portion of the substrate 110 and the hook structure 120A according to an embodiment of the invention. Compared to the embodiment shown in fig. 3B, the end of the hook structure 120A of the present embodiment has a smooth shape, and still has a stop portion 121a, where the stop portion 121a stops the plastic connecting element 130 and prevents the plastic connecting element 130 from being pulled out from the hook structure 120A in a direction away from the substrate 110.
Fig. 6 is a perspective view illustrating a portion of the substrate 110 and the hook structure 120B according to an embodiment of the invention. Compared to the embodiment shown in fig. 3B, the hook structure 120B of the present embodiment has a shape inclined linearly with respect to the substrate 110, and still has a configuration of a stopping portion 121B, where the stopping portion 121B stops the plastic connecting element 130 and prevents the plastic connecting element 130 from being pulled out from the hook structure 120B in a direction away from the substrate 110.
Fig. 7 is a perspective view illustrating a portion of the substrate 110 and the hook structure 120C according to an embodiment of the invention. Compared to the embodiment shown in fig. 3B, the hook structure 120C of the present embodiment has an arrow shape at the end, and still has a stop portion 121C, the stop portion 121C stops the plastic connecting element 130 and prevents the plastic connecting element 130 from being pulled out of the hook structure 120C in a direction away from the substrate 110. Furthermore, each of the hook structures 120C of the present embodiment has two stop portions 121C respectively located at two opposite sides, so as to increase the area of the stop portions 121C, thereby better preventing the plastic connecting element 130 from being pulled out.
Fig. 8 is a perspective view illustrating a portion of the substrate 110 and the hook structure 120D according to an embodiment of the invention. Compared to the embodiment shown in fig. 3B, the hook structure 120D of the present embodiment still has the stop portion 121D, and the stop portion 121D stops the plastic connecting element 130 and prevents the plastic connecting element 130 from being pulled out of the hook structure 120D in a direction away from the substrate 110. In particular, the hook structure 120D of the present embodiment is adjacent to one side edge of the through hole 112 and stands up relative to the surface of the substrate 110, and extends toward the other side edge of the through hole 112, so as to increase the area of the stopping portion 121D, thereby better preventing the plastic connecting element 130 from being pulled out.
Fig. 9 is a perspective view illustrating a portion of the substrate 110 and the hook structure 120E according to an embodiment of the invention. Compared to the embodiment shown in fig. 3B, the hook structure 120E of the present embodiment still has the stop portion 121E, and the stop portion 121E stops the plastic connecting element 130 and prevents the plastic connecting element 130 from being pulled out of the hook structure 120E in a direction away from the substrate 110. Moreover, compared to the hook structure 120D in the embodiment shown in fig. 8, the hook structure 120E of the present embodiment further includes a portion extending in the through hole 112, so as to increase the fixing area between the hook structure 120E and the plastic connecting element 130, thereby providing better fixing strength for the hook structure 120E and the plastic connecting element. Furthermore, the hook structure 120E of the present embodiment has more bent portions, so the structural strength can be improved (e.g., the stress concentration phenomenon occurs after multiple bending processes).
Referring to fig. 10, a cross-sectional view of a portion of the substrate 110, the hook structure 120 and the plastic link 230 according to an embodiment of the invention is shown. As shown in fig. 10, in the present embodiment, the substrate 110 and the hook structure 120 are the same as or similar to the embodiment shown in fig. 3B, so that the two elements can refer to the related descriptions above, and are not repeated herein. It should be noted that, compared to the embodiment shown in fig. 4, the plastic connecting element 230 of the present embodiment is completely located outside the through hole 112, that is, any portion of the plastic connecting element 230 is not filled in the through hole 112, but the hook structure 120 can still achieve the purpose of fixing the plastic connecting element 230 to each other. Since the plastic connectors 230 are only fixed to the hook structures 120, the top surface 111 of the substrate 110 can be kept flat. In the embodiment shown in fig. 10, the bottom surface of the plastic adaptor 230 is aligned with the top surface 111 of the substrate 110, but the invention is not limited thereto. In practical applications, the bottom surface of the plastic adaptor 230 may also be located above the top surface 111 of the substrate 110. In addition, in the embodiment shown in fig. 10, the plastic connectors 230 and the substrate 110 are not adjacent to each other, but the invention is not limited thereto. In practical applications, the plastic connectors 230 may also abut the top surface 111 of the substrate 110, which may increase the structural stability of the plastic connectors 230 on the substrate 110.
Please refer to fig. 11 and 12. Fig. 11 is an exploded view of a portion of the substrate 310, the hook structure 120 and the plastic link 230 according to an embodiment of the invention. FIG. 12 is a cross-sectional view of the structure of FIG. 11 taken along line 12-12. As shown in fig. 11 and 12, in the present embodiment, the hooking structure 120 is the same as or similar to the embodiment shown in fig. 3B, and the plastic engaging member 230 is the same as or similar to the embodiment shown in fig. 10, so that these two elements can refer to the related descriptions above, and will not be repeated herein. It should be noted that, compared to the embodiment shown in fig. 3B, the substrate 310 of the present embodiment has two through holes 312a and 312B and a rib 314 separating the two through holes 312a and 312B. The two hook structures 120 are respectively adjacent to the two through holes 312a and 312 b. The plastic engaging member 230 is fixed to the two hook structures 120 at the same time. The ribs 314 are configured to support the bottom of the plastic link 230 from below, thereby improving the structural stability of the combination of the base plate 310, the hook structure 120, and the plastic link 230. In this embodiment, the plastic connectors 230 are completely located outside the through holes 312a, 312b, but not limited thereto. In some embodiments, the plastic adaptor 230 may also partially fill one or more specific locations (e.g., one or more edges or corners) within the through holes 312a, 312b, respectively.
As is apparent from the above detailed description of the embodiments of the present invention, the keyboard of the present invention utilizes the plastic connecting member disposed on the substrate to connect with the guiding connection structure, instead of the conventional keyboard, which utilizes the hook on the metal bottom plate to connect with the guiding connection structure. The plastic connecting piece arranged on the substrate can increase the structural strength of the substrate, thereby effectively avoiding the problem of deformation of the substrate and/or the clamping hook caused by compression when the guide connecting structure is assembled or the keycap is pressed, and further thinning the substrate to realize the purposes of light weight and thinning the keyboard. Moreover, the assembly tolerance between the plastic connecting piece and the guiding connecting structure can be controlled by the manufacturing precision of the plastic connecting piece, and the keyboard can not be influenced by the processing precision when the existing keyboard is bent and clamped, so the assembly precision of the keyboard can be improved.
Although the present invention has been described with reference to the above embodiments, it should be understood that the present invention is not limited thereto, and various changes and modifications can be made by those skilled in the art without departing from the spirit and scope of the present invention.
