Description

Technical Field

[0001] The invention relates to a keyboard, in particular to a bottom plate of a keyboard. Background Art

[0002] In terms of current computer usage habits, the keyboard is one of the indispensable input devices. Generally speaking, the main structure of the keyboard includes a base plate, a circuit board and multiple key structures. Common key structures include keycaps and connecting components. Among them, the most common connecting component is a scissor-type connector. The keycap and the base plate are connected by a scissor-type connector to drive the keycap to rise and fall relative to the base plate.

[0003] Specifically, the scissor-type connector includes an outer frame and an inner frame pivotally connected to each other. A common structure is that one end of the outer frame is movably disposed on the bottom side of the keycap, and the other end is restricted by a hook on the bottom plate. Similarly, one end of the inner frame is pivotally connected to the bottom side of the keycap, and the other end is movably disposed on another hook on the bottom plate. Through the above structure, the scissor-type connector can drive the keycap to move up and down relative to the bottom plate.

[0004] When the keycap moves up and down relative to the base plate, the hook needs to withstand the force from the scissor-type connector. However, computer peripherals are now also developing towards the design concept of light, thin, short and small. In order to reduce the weight of the keyboard, some designs replace the base plate with a lightweight material, such as aluminum. If the hook on the base plate is changed to a lightweight material, the strength of the hook will be weakened, and it will not be able to withstand the force from the scissor-type connector, which is necessary for improvement. Summary of the invention

[0005] In view of the above problems, the main purpose of the present invention is to provide a keyboard, which solves the problem of weak strength of the conventional lightweight base plate by designing a lightweight body and a reinforcing member included in a base plate assembly.

[0006] To achieve the above-mentioned purpose, the present invention provides a keyboard, which includes at least one key structure and a base plate assembly. The key structure includes a connecting assembly. The base plate assembly includes a lightweight body and at least one reinforcement member. The lightweight body includes at least one supporting portion. The supporting portion protrudes from the lightweight body toward the key structure. The reinforcement member includes at least one fixing portion and at least one first hook. The fixing portion is arranged on the lightweight body, and the first hook protrudes from the fixing portion toward the key structure. The supporting portion is arranged on a side wall of the first hook, and the connecting assembly is assembled to the first hook.

[0007] According to an embodiment of the present invention, the configuration of the supporting portion is substantially the same as the configuration of the first hook.

[0008] According to an embodiment of the present invention, the first hook includes a first part and a second part. One end of the first part is connected to the fixing part, and the second part is connected to the other end of the first part. Moreover, the second part protrudes from the first part. The supporting part is arranged on the first part.

[0009] According to an embodiment of the present invention, the connecting component is limited by the supporting portion and the second portion.

[0010] According to an embodiment of the present invention, the fixing portion is disposed on a surface of the lightweight body facing the key structure.

[0011] According to an embodiment of the present invention, the lightweight body is an aluminum plate.

[0012] According to an embodiment of the present invention, the reinforcing piece includes a plurality of fixing portions, and the reinforcing piece further includes at least one connecting portion, wherein the connecting portion connects two adjacent fixing portions.

[0013] According to an embodiment of the present invention, the connecting assembly includes a first frame and a second frame pivotally connected to each other. The lightweight body includes at least one second hook. One end of the first frame is connected to the first hook, and one end of the second frame is connected to the second hook.

[0014] According to an embodiment of the present invention, the end of the first frame is pivotally connected to the first hook, and the end of the second frame is movably connected to the second hook.

[0015] According to one embodiment of the present invention, the connecting assembly includes a first frame and a second frame pivotally connected to each other. The reinforcing member includes at least one third hook. The lightweight body includes a plurality of supporting portions. The supporting portions are respectively arranged on a side wall of the first hook and a side wall of the third hook.

[0052] In order to better understand the technical content of the present invention, preferred specific embodiments are described below.

[0053] Figure 1 is an exploded schematic diagram of a keyboard according to a first embodiment of the present invention, Figure 2 for Figure 1 A side view of the keyboard is shown. Figure 3 for Figure 1 For a schematic diagram of the base plate assembly shown, refer to Figure 1 , Figure 2 and Figure 3 In this embodiment, the keyboard 1 includes at least one key structure 10 and a bottom plate assembly 20. It should be noted that the keyboard 1 of this embodiment includes a plurality of key structures 10. For the sake of clarity, Figure 1 and Figure 2Only one of the key structures 10 is drawn, and only part of the bottom plate assembly 20 is drawn, for example, part of the bottom plate assembly 20 corresponding to six key structures 10. Each key structure 10 includes a connecting assembly 11 and a key cap 12. The connecting assembly 11 is connected to the key cap 12 and the bottom plate assembly 20 respectively. The connecting assembly 11 of this embodiment is a scissor-type connecting member, which includes a first frame 111 and a second frame 112 pivotally connected to each other. One end of the first frame 111 is pivotally connected to the bottom plate assembly 20, and the other end is movably connected to the key cap 12. The second frame 112 is pivotally connected to the key cap 12 at one end, and movably connected to the bottom plate assembly 20 at the other end. Through the aforementioned connection relationship, the connecting assembly 11 can drive the key cap 12 to rise and fall relative to the bottom plate assembly 20. The first frame 111 of this embodiment is an outer frame, and the second frame 112 is an inner frame. In other embodiments, the second frame 112 can also be an outer frame, and the first frame 111 can be an inner frame, and the present invention is not limited.

[0054] In this embodiment, the bottom plate assembly 20 includes a lightweight body 21 and at least one reinforcing member 22. The lightweight body 21 is a bottom plate structure made of lightweight material. This embodiment takes an aluminum plate as an example, but the present invention is not limited thereto. The lightweight body 21 includes at least one supporting portion 211. This embodiment takes multiple supporting portions 211 as an example. Figure 1 and Figure 3 As shown, the support portion 211 protrudes from the lightweight body 21 toward the key structure 10. Preferably, the support portion 211 is perpendicular to the lightweight body 21. Specifically, the lightweight body 21 has a hollow structure corresponding to each key structure 10 to reduce the overall weight of the bottom plate assembly 20. The hollow structure of the lightweight body 21 can be formed by punching, and the planar support portion 211 structure can be formed first, such as Figure 4 shown. Figure 4 for Figure 3 The bottom plate assembly is shown as an enlarged schematic diagram of the part after stamping. Next, it is bent upward to form a support portion 211 protruding toward the key structure 10, as shown in FIG. Figure 1 , Figure 3 and Figure 5 shown. Figure 5 for Figure 3 A partial enlarged schematic diagram of the bottom plate assembly is shown. In this embodiment, corresponding to each key structure 10, the lightweight body 21 has two supporting portions 211. It should also be noted that the lightweight body 21 may or may not have a hook, and the details will be further described later.

[0055] In the present embodiment, the bottom plate assembly 20 includes a plurality of reinforcing members 22, and the hardness of the reinforcing members 22 is higher than that of the lightweight body 21. The following first takes one of the reinforcing members 22 as an example. The reinforcing member 22 includes at least one fixing portion 221 and at least one first hook 222. The reinforcing member 22 of the present embodiment takes a plurality of fixing portions 221 and a plurality of first hooks 222 as an example. The structure of the fixing portion 221 and the first hook 222 is first described below, and the quantitative relationship thereof is described in detail later. The fixing portion 221 is disposed on the lightweight body 21, and the first hook 222 protrudes from the fixing portion 221 toward the direction of the key structure 10. In other words, the supporting portion 211 and the first hook 222 are structures that protrude toward the direction of the key structure 10. Specifically, the reinforcing member 22 of the present embodiment is preferably made of stainless steel. In other embodiments, the reinforcing member 22 may also be made of iron plate or other materials having a strength higher than that of the lightweight body 21 (i.e., aluminum plate). The reinforcing member 22 may also be firstly punched to form a fixing portion 221 and a planar first hook 222 (eg Figure 4 ), and then bends upward to form a first hook 222 protruding toward the key structure 10 (as shown in FIG. Figure 1 , Figure 3 and Figure 5 shown).

[0056] Furthermore, the position of the support portion 211 corresponds to the first hook 222, so that the support portion 211 can be disposed on the side wall of the first hook 222. In the present embodiment, the support portion 211 is disposed on the outer side wall of the first hook 222. It should be noted that the side of the first hook 222 facing the fixing portion 221 is called the inner side wall, and conversely, the side of the first hook 222 away from the fixing portion 221 is called the outer side wall. Furthermore, in the present embodiment, the fixing portion 221 refers to a portion disposed on the lightweight body 21 and close to the first hook 222. In other words, the fixing portion 221 is disposed on the upper surface of the lightweight body 21 and close to the first hook 222.

[0057] Preferably, the lightweight body 21 and the reinforcing member 22 also have at least one positioning hole 212, 223, respectively. Figure 1 As shown. The positioning hole 212 is close to the supporting portion 211, and the positioning hole 223 is located at the fixing portion 221. When manufacturing the bottom plate assembly 20, the stamped reinforcement member 22 (such as Figure 4 As shown, the first hook 222 having a plane and the lightweight body 21 after stamping (as shown Figure 4 As shown, the support portion 211 with a plane is placed together in a mold with a positioning pin. The reinforcing member 22 is placed on the upper surface of the lightweight body 21, and the two positioning holes 212, 223 are positioned with each other by the positioning pin.

[0058] Next, the lightweight body 21 and the reinforcing member 22 are joined by welding or gluing. Finally, the support portion 211 and the first hook 222 are bent so that the support portion 211 and the first hook 222 are both protruded toward the key structure 10. Since the lightweight body 21 is located on the lower surface of the reinforcing member 22, when the support portion 211 and the first hook 222 are bent, the support portion 211 can be located on the outer side wall of the first hook 222, such as Figure 1 , Figure 3 and Figure 5 The support portion 211 can support the first hook 222 , thereby increasing the strength of the first hook 222 .

[0059] In other embodiments, the aluminum plate and the stainless steel plate may be first joined and then punched at the same time, so that the lightweight body 21 forms the aforementioned hollow structure, the (planar) support portion 211 and the positioning hole 212 and other structures, and the reinforcing member 22 forms the fixing portion 221 and the (planar) first hook 222 and other structures. Finally, the support portion 211 and the first hook 222 are bent to protrude toward the direction of the key structure 10. In other words, the present invention does not limit the process sequence of the bottom plate assembly 20.

[0060] After the base plate assembly 20 is prepared, the connecting assembly 11 of the button structure 10 is assembled to the base plate assembly 20. Among them, the connecting assembly 11 is assembled to the first hook 222. In the present embodiment, one end of the first frame 111 is connected to the first hook 222, and the first frame 111 is connected to the lightweight body 21. Specifically, the lightweight body 21 of the present embodiment includes at least one second hook 213, and multiple second hooks 213 are used as an example here. In addition to forming a planar support portion 211, the lightweight body 21 after the aforementioned stamping can also form a planar second hook 213. Subsequently, it is bent to form a support portion 211 and a second hook 213 protruding toward the button structure 10. In the present embodiment, one end of the first frame 111 is connected to the first hook 222 of the reinforcement 22, and one end of the second frame 112 is connected to the second hook 213 of the lightweight body 21.

[0061] Preferably, one end of the first frame 111 is pivotally connected to the first hook 222, and one end of the second frame 112 is movably connected to the second hook 213. Figure 2In other words, the first frame 111 is connected to the first hook 222 at a pivot end (hereinafter referred to as the pivot shaft 1111), and the second frame 112 is connected to the second hook 213 at a movable end. Generally speaking, when the keycap 12 is assembled to the base plate assembly 20, the sliding shaft 1112 is first positioned, and then the pivot shaft 1111 is installed to the hook (i.e., the first hook 222). Therefore, the hook connected to the pivot shaft 1111 (i.e., the first hook 222) is more easily damaged during the assembly process. In this embodiment, the first hook 222 is a reinforcing member 22 with higher strength, and the support portion 211 is disposed on the side wall of the first hook 222, so the aforementioned easy damage situation can be avoided.

[0062] like Figure 4 and Figure 5 As shown, the first hook 222 includes a first part 2221 and a second part 2222. Among them, one end of the first part 2221 is connected to the fixing part 221, and the second part 2222 is connected to the other end of the first part 2221. In addition, the second part 2222 protrudes from the first part 2221 in a direction parallel to the fixing part 221 to form a hook-shaped structure. In other words, the first hook 222 is sequentially composed of the first part 2221 and the second part 2222 in the direction from the fixing part 221 to the key structure 10, and the upper hook-shaped part is the second part 2222. In this embodiment, the support part 211 is disposed on the side wall of the first part 2221, and is located on the outer side wall of the first part 2221, as shown in FIG. Figure 5 It should be noted that Figure 4 The support portion 211 and the first hook 222 are shown before being bent, so the support portion 211 and the second portion 2222 partially overlap. Figure 5 As shown in FIG. 2 , the support portion 211 will move downward and be located on the outer side wall of the first portion 2221 .

[0063] In this embodiment, the width W1 of the support portion 211 is greater than the width W2 of the first portion 2221. Therefore, the pivot shaft 1111 of the first frame 111 is located outside the support portion 211. Figure 2 That is, the support portion 211 can limit the pivot axis 1111 of the first frame 111. In this embodiment, the connecting component 11 is limited by the support portion 211 and the second portion 2222. Please also refer to Figure 2 and Figure 4As shown, the pivot shaft 1111 of the first frame 111 is connected to the first hook 222, the top edge of the pivot shaft 1111 is limited by the second portion 2222 of the first hook 222, and the left side of the pivot shaft 1111 is limited by the support portion 211. In addition, since the support portion 211 can limit the left side of the pivot shaft 1111, the span of movement of the connecting component 11 can be defined by the distance between the support portion 211 and the second hook 213. In other embodiments, the width W1 of the support portion 211 can be smaller than the width W2 of the first portion 2221. At this time, the pivot shaft 1111 of the first frame 111 is located outside the first portion 2221 of the first hook 222. Therefore, the span of movement of the connecting component 11 can be defined by the distance between the first hook 222 and the second hook 213.

[0064] In other embodiments, the width W1 of the support portion 211 may also be equal to the width W2 of the first portion 2221, and the present invention is not limited thereto. In this case, the pivot axis 1111 of the first frame 111 is located outside the support portion 211 and the first portion 2221 of the first hook 222. The moving span of the connecting component 11 may be defined by the distance between the support portion 211 or the first hook 222 and the second hook 213. It should be noted that the support portion 211 and the second hook 213 are both located on the lightweight body 21, and both are formed by stamping the same mold with high precision. Therefore, defining the moving span of the connecting component 11 by the distance between the support portion 211 and the second hook 213 can avoid the tolerance generated when the reinforcing member 22 is assembled with the lightweight body 21 and affecting the moving span of the connecting component 11. When implementing the present invention, the span may be defined by the first hook 222 or the support portion 211 according to the requirements of the assembly equipment and the product, and the present invention is not limited thereto.

[0065] As mentioned above, the bottom plate assembly 20 of this embodiment includes a plurality of reinforcing members 22. The number of reinforcing members 22 of this embodiment is less than the number of key structures 10. In one embodiment, the number of reinforcing members 22 may be equal to the number of rows of key structures 10 of the keyboard 1. For example, a common keyboard 1 is configured with six rows of key structures 10, and six reinforcing members 22 may be provided. Figure 1 and Figure 2 Only a partial structure of the keyboard 1 is shown, and thus the configuration of two reinforcing members 22 corresponding to three key structures 10 is taken as an example for explanation.

[0066] In addition, each reinforcing member 22 of the present embodiment also includes a plurality of fixing portions 221 and a plurality of first hooks 222. The number of the first hooks 222 can be defined according to the number of the pivot shafts 1111 of the first frame 111. For example, if each reinforcing member 22 corresponds to three key structures 10, and the first frame 111 has two pivot shafts 1111, each reinforcing member 22 can have six first hooks 222. Similarly, the number of the second hooks 213 of the lightweight body 21 can be defined according to the number of the moving ends of the second frame 112.

[0067] Since the fixing portion 221 is close to the first hook 222, the number of the fixing portions 221 may be less than or equal to the number of the first hooks 222. In this embodiment, there is a fixing portion 221 between two adjacent first hooks 222, so the number of the fixing portions 221 is less than the number of the first hooks 222. In addition, the reinforcing member 22 also includes at least one connecting portion 224, and this embodiment takes a plurality of connecting portions 224 as an example. The connecting portion 224 connects two adjacent fixing portions 221, so that one reinforcing member 22 can correspond to a plurality of key structures 10. In this embodiment, the connecting portion 224 connects two adjacent fixing portions 221 located in the same row.

[0068] Figure 6 is a schematic diagram of a base plate assembly 20a according to a second embodiment of the present invention, Figure 7 for Figure 6 Please refer to the enlarged schematic diagram of the bottom plate assembly shown in Figure 6 and Figure 7 As shown. The bottom plate assembly 20a of the present embodiment also includes a lightweight body 21a and two reinforcing members 22. Among them, the configuration of the reinforcing member 22 is the same as that of the first embodiment, so its label is used. The difference between the lightweight body 21a of the present embodiment and the lightweight body 21 of the first embodiment is that the support portion 211a of the lightweight body 21a has a convex step extending into a hook, so that the configuration of the support portion 211a is substantially the same as the configuration of the first hook 222 of the reinforcing member 22. Therefore, the support portion 211a of the present embodiment can be connected to the pivot shaft 1111 of the first frame 111 together with the first hook 222 (please refer to Figure 1 and Figure 2 shown).

[0069] In this embodiment, the bottom plate assembly 20a can be prepared by first joining an aluminum plate and a stainless steel plate and then punching holes at the same time, so that the lightweight body 21a forms a (planar) support portion 211a, and the reinforcing member 22 forms a (planar) first hook 222. Finally, the support portion 211a and the first hook 222 are bent to ensure that the size of the support portion 211a and the first hook 222 are consistent.

[0070] Figure 8 This is a schematic diagram of a base plate assembly according to a third embodiment of the present invention. Figure 8 As shown. The bottom plate assembly 20b of this embodiment also includes a lightweight body 21 and a reinforcement piece 22b. Among them, the configuration of the lightweight body 21 is the same as that of the first embodiment, so its label is used. The difference between the reinforcement piece 22b of this embodiment and the reinforcement piece 22 of the first embodiment is that the reinforcement piece 22b has both a transverse and a longitudinal connection portion 224b. The transverse and longitudinal connection portions 224b can connect two adjacent fixing portions 221b located in the same row and different rows, thereby reducing the number of reinforcement pieces 22b. For example, the bottom plate assembly 20b of this embodiment has only one reinforcement piece 22b. Among them, regarding the structure of the first hook 222b of the reinforcement piece 22b and its connection relationship with the support portion 211, reference can be made to the aforementioned embodiment and no further details are given here.

[0071] Fig. 9 FIG. 1 is a schematic diagram of a base plate assembly according to a fourth embodiment of the present invention. Fig. 9 As shown. The bottom plate assembly 20c of this embodiment also includes a lightweight body 21 and a reinforcing member 22c. Among them, the configuration of the lightweight body 21 is the same as that of the first embodiment, so its number is used. The reinforcing member 22c of this embodiment also includes a fixing portion 221c, a first hook 222c and a connecting portion 224c. The difference from the first embodiment is that the number of reinforcing members 22c of this embodiment is equal to the number of key structures 10 (please refer to the key structure 10). Figure 1 ). Specifically, each reinforcing member 22c includes two fixing portions 221c and two first hooks 222c, and a connecting portion 224c connects two adjacent fixing portions 221c. Adjacent fixing portions 221c corresponding to two key structures 10 are not connected to each other, so that each reinforcing member 22c can correspond to one key structure 10 respectively. Similarly, regarding the structure of the first hook 222c and its connection relationship with the supporting portion 211, reference can be made to the aforementioned embodiment, and no further description is given here.

[0072] Fig.10 FIG. 1 is a schematic diagram of a base plate assembly according to a fifth embodiment of the present invention. Fig.10 As shown. The bottom plate assembly 20d of this embodiment also includes a light body 21 and a reinforcing member 22d. The configuration of the light body 21 is the same as that of the first embodiment, so the same reference numeral is used. The difference from the first embodiment is that the reinforcing member 22d of this embodiment includes a fixing portion 221d and a first hook 222d, but does not have a connecting portion 224. In other words, the first frame 111 (see FIG. 11 ) of the connecting assembly 11 can be connected to the reinforcing member 22d. Figure 1 or Figure 2The reinforcing member 22d is arranged at the position of the first frame 111 (as shown in FIG. 1 ), so that the first frame 111 can be pivotally connected to the first hook 222d. Since the single first frame 111 of this embodiment needs to connect two first hooks 222d, the bottom plate assembly 20d includes a plurality of reinforcing members 22d, and the number of reinforcing members 22d is greater than twice the number of the key structures 10. In addition, the structure of the first hook 222d and its connection relationship with the support portion 211 can be referred to the aforementioned embodiment, and no further description is given here.

[0073] Fig.11 FIG. 1 is a schematic diagram of a bottom plate assembly according to a sixth embodiment of the present invention. Fig.11 The bottom plate assembly 20e of this embodiment also includes a lightweight body 21e and a reinforcing member 22e. The lightweight body 21e of this embodiment does not have the second hook 213 of the aforementioned embodiment (please refer to Figure 1 , Figure 3 and Figure 5 ), but a support portion 211e is provided at the position of the original second hook 213. In other words, compared with the first embodiment, the number of support portions 211e in this embodiment is twice that of the first embodiment. Correspondingly, the reinforcing member 22e includes at least one third hook 225e in addition to the fixing portion 221e, the first hook 222e and the connecting portion 224e. The support portions 211e are respectively provided on the side walls of the first hook 222e and the side walls of the third hook 225e.
