Description

Keyboard

The present invention relates to a keyboard, and in particular to a bottom plate of a keyboard.

In terms of current computer usage habits, the keyboard is one of the indispensable input devices. Generally speaking, the main structure of a keyboard includes a base plate, a circuit board, and a plurality of key structures. Common key structures include key caps and connection components. Among them, the most common connection component is a scissor-type connector. The scissor-type connector connects the key cap and the base plate to drive the key cap to rise and fall relative to the base plate.

Specifically, the scissor-type connector includes an outer frame and an inner frame that are 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 key cap, and the other end is limited to a hook on the bottom plate. Similarly, one end of the inner frame is pivotally connected to the bottom side of the key cap, and the other end is movably disposed on another hook on the bottom plate. With the aforementioned structure, the scissor-type connector can drive the key cap to move up and down relative to the bottom plate.

When the keycap moves up and down relative to the base, the hook needs to bear 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 with a lightweight material, such as aluminum. If the hook on the base is changed to a lightweight material, the strength of the hook will be weakened, and it will not be able to bear the force from the scissor-type connector, which is necessary for improvement.

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 base plate made of lightweight material by designing a base plate assembly including a lightweight body and a reinforcing member.

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. The lightweight body includes at least one supporting portion. The supporting portion protrudes from the lightweight body toward the key structure. The reinforcement 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.

According to one embodiment of the present invention, the configuration of the supporting portion is substantially the same as the configuration of the first hook.

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.

According to one embodiment of the present invention, the connecting assembly is limited by the supporting portion and the second portion.

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

According to one embodiment of the present invention, the lightweight body is an aluminum plate.

According to an embodiment of the present invention, the reinforcing member includes a plurality of fixing portions, and the reinforcing member further includes at least one connecting portion. The connecting portion connects two adjacent fixing portions.

According to an embodiment of the present invention, the connection 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.

According to one 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.

According to an embodiment of the present invention, the connection assembly includes a first frame and a second frame pivotally connected to each other. The reinforcement includes at least one third hook. The lightweight body includes a plurality of supporting parts. The supporting parts are respectively arranged on a side wall of the first hook and a side wall of the third hook.

According to one 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 third hook.

As described above, according to the keyboard of the present invention, the bottom plate assembly includes a lightweight body and at least one reinforcement member. The lightweight body includes at least one supporting portion, and the reinforcement member includes at least one first hook. The supporting portion is arranged on a side wall of the first hook, and the connecting assembly is assembled to the first hook. The first hook is a reinforcement member with high strength, which can achieve the effect of improving the bottom plate assembly. In addition, the supporting portion is arranged on the side wall of the first hook, which can increase the strength of the first hook, thereby improving the durability of the first hook.

In order to better understand the technical content of the present invention, the preferred specific embodiments are described as follows.

FIG1 is an exploded schematic diagram of the keyboard of the first embodiment of the present invention, FIG2 is a side view of the keyboard shown in FIG1, and FIG3 is a schematic diagram of the bottom plate assembly shown in FIG1. Please refer to FIG1, FIG2 and FIG3. 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 of the drawings, FIG1 and FIG2 only depict one of the key structures 10, and only depict a portion of the bottom plate assembly 20, for example, a portion 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 the present embodiment is a scissor-type connecting member, which includes a first frame 111 and a second frame 112 pivoted to each other. One end of the first frame 111 is pivoted to the bottom plate assembly 20, and the other end is movably connected to the key cap 12. One end of the second frame 112 is pivoted to the key cap 12, and the other end is movably connected to the bottom plate assembly 20. 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 the present 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 thereto.

In the present embodiment, the base plate assembly 20 includes a lightweight body 21 and at least one reinforcement member 22. The lightweight body 21 is a base plate structure made of lightweight material. The present 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. The present embodiment takes a plurality of supporting portions 211 as an example. As shown in FIGS. 1 and 3 , the supporting portion 211 protrudes from the lightweight body 21 toward the key structure 10. Preferably, the supporting portion 211 is perpendicular to the lightweight body 21. Specifically, the lightweight body 21 has a hollowed-out structure corresponding to each key structure 10 to reduce the overall weight of the base plate assembly 20. The hollow structure of the lightweight body 21 is formed by punching, and the planar support portion 211 structure can be formed first, as shown in FIG4. FIG4 is a partially enlarged schematic diagram of the bottom plate assembly shown in FIG3 after punching. Then, it is bent upward to form a support portion 211 protruding toward the key structure 10, as shown in FIG1, FIG3 and FIG5. FIG5 is a partially enlarged schematic diagram of the bottom plate assembly shown in FIG3. In this embodiment, corresponding to each key structure 10, the lightweight body 21 has two support 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.

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. One of the reinforcing members 22 is first used as an example for explanation below. 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 is taken as an example of a plurality of fixing portions 221 and a plurality of first hooks 222. The structure of the fixing portions 221 and the first hooks 222 is first described below, and the relationship of their quantities 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 both structures that protrude toward the direction of the key structure 10. Specifically, the reinforcing member 22 of this embodiment is preferably made of stainless steel. In other embodiments, the reinforcing member 22 may also be made of iron plate or other materials with higher strength than the lightweight body 21 (i.e., aluminum plate). The reinforcing member 22 may also be first stamped to form a fixing portion 221 and a planar first hook 222 (as shown in FIG. 4 ), and then bent upward to form a first hook 222 protruding toward the key structure 10 (as shown in FIG. 1 , FIG. 3 , and FIG. 5 ).

Furthermore, the position of the supporting portion 211 corresponds to the first hook 222, so that the supporting portion 211 can be disposed on the side wall of the first hook 222. In this embodiment, the supporting 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 this 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.

Preferably, the lightweight body 21 and the reinforcement 22 also have at least one positioning hole 212, 223, respectively, as shown in FIG1. The positioning hole 212 is close to the support portion 211, and the positioning hole 223 is located at the fixing portion 221. When manufacturing the bottom plate assembly 20, the punched reinforcement 22 (as shown in FIG4, having a planar first hook 222) and the punched lightweight body 21 (as shown in FIG4, having a planar support portion 211) can be placed together in a mold with a positioning pin. The reinforcement 22 is placed on the upper surface of the lightweight body 21, and the two positioning holes 212, 223 are mutually positioned by the positioning pin.

Next, the lightweight body 21 and the reinforcement 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 both protrude toward the key structure 10. Since the lightweight body 21 is located on the lower surface of the reinforcement 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, as shown in Figures 1, 3 and 5. The support portion 211 can support the first hook 222, thereby increasing the strength of the first hook 222.

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 hollowed-out 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 manufacturing process sequence of the bottom plate assembly 20.

After the base plate assembly 20 is prepared, the connecting assembly 11 of the key structure 10 is assembled to the base plate assembly 20. The connecting assembly 11 is assembled to the first hook 222. In this 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 this embodiment includes at least one second hook 213, and a plurality of second hooks 213 are used as an example for explanation. In addition to forming a planar supporting portion 211, the lightweight body 21 after the aforementioned stamping can also form a planar second hook 213. It is then bent to form the supporting portion 211 and the second hook 213 protruding toward the key structure 10. In this 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 .

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, as shown in FIG2. In 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 key cap 12 is assembled to the bottom 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 (i.e., the first hook 222) connected to the pivot shaft 1111 is more easily damaged during the assembly process. In this embodiment, the first hook 222 is a reinforcing member 22 with high strength, and the supporting portion 211 is disposed on the side wall of the first hook 222, so the aforementioned easy damage situation can be avoided.

As shown in FIG. 4 and FIG. 5 , the first hook 222 includes a first portion 2221 and a second portion 2222. One end of the first portion 2221 is connected to the fixing portion 221, and the second portion 2222 is connected to the other end of the first portion 2221. Moreover, the second portion 2222 protrudes from the first portion 2221 in a direction parallel to the fixing portion 221 to form a hook-shaped structure. In other words, the first hook 222 is sequentially the first portion 2221 and the second portion 2222 in the direction from the fixing portion 221 to the key structure 10, and the upper hook-shaped portion is the second portion 2222. In this embodiment, the supporting portion 211 is disposed on the side wall of the first portion 2221 and is located on the outer side wall of the first portion 2221, as shown in FIG. 5 . It should be noted that FIG4 shows the support portion 211 and the first hook 222 before bending, so the support portion 211 partially overlaps with the second portion 2222. After the support portion 211 and the first hook 222 are bent (as shown in FIG5), the support portion 211 moves downward and is located on the outer side wall of the first portion 2221.

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 axis 1111 of the first frame 111 is located outside the support portion 211, as shown in FIG. 2. That is, the support portion 211 can limit the pivot axis 1111 of the first frame 111. In this embodiment, the connection assembly 11 is limited by the support portion 211 and the second portion 2222. Please refer to FIG. 2 and FIG. 4 , the pivot axis 1111 of the first frame 111 is connected to the first hook 222, the top edge of the pivot axis 1111 is limited by the second portion 2222 of the first hook 222, and the left side of the pivot axis 1111 is limited by the support portion 211. In addition, since the support portion 211 can limit the left side of the pivot axis 1111, the span of movement of the connecting assembly 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 axis 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 assembly 11 can be defined by the distance between the first hook 222 and the second hook 213.

In other embodiments, the width W1 of the support portion 211 may 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 span of movement of the connecting assembly 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, by defining the distance between the support portion 211 and the second hook 213 to define the moving span of the connecting component 11, it is possible to avoid the tolerance generated when assembling the reinforcement 22 and the lightweight body 21 and affecting the moving span of the connecting component 11. When implementing the present invention, the span can 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.

As mentioned above, the bottom plate assembly 20 of the present embodiment includes a plurality of reinforcing members 22. The number of reinforcing members 22 of the present 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. Since FIG. 1 and FIG. 2 only depict a partial structure of the keyboard 1, two reinforcing members 22 corresponding to a configuration of three key structures 10 are used as an example for explanation.

In addition, each reinforcement 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 pivots 1111 of the first frame 111. For example, if each reinforcement member 22 corresponds to three key structures 10 and the first frame 111 has two pivots 1111, each reinforcement 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.

Since the fixing portion 221 is close to the first hook 222, the number of the fixing portions 221 can be less than or equal to the number of the first hooks 222. In this embodiment, there is one 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 reinforcement member 22 further 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 reinforcement member 22 can correspond to multiple key structures 10. In this embodiment, the connecting portion 224 connects two adjacent fixing portions 221 located in the same row.

FIG6 is a schematic diagram of a bottom plate assembly 20a of the second embodiment of the present invention, and FIG7 is a partially enlarged schematic diagram of the bottom plate assembly shown in FIG6 , please refer to FIG6 and FIG7 . The bottom plate assembly 20a of this 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 number is used. The difference between the lightweight body 21a of this 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 supporting portion 211a of this embodiment can be connected to the pivot axis 1111 of the first frame 111 together with the first hook 222 (please refer to FIG. 1 and FIG. 2 ).

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 reinforcement 22 forms a (planar) first hook 222. Finally, the support portion 211a and the first hook 222 are bent to ensure that the sizes of the support portion 211a and the first hook 222 are consistent.

FIG8 is a schematic diagram of the bottom plate assembly of the third embodiment of the present invention, please refer to FIG8. The bottom plate assembly 20b of this embodiment also includes a lightweight body 21 and a reinforcement 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 22b of this embodiment and the reinforcement 22 of the first embodiment is that the reinforcement 22b has both transverse and longitudinal connecting portions 224b. The transverse and longitudinal connecting portions 224b can connect two adjacent fixing portions 221b located in the same row and different rows, thereby reducing the number of reinforcements 22b. For example, the bottom plate assembly 20b of this embodiment has only one reinforcement 22b. The structure of the first hook 222b of the reinforcing member 22b and its connection with the supporting portion 211 can be found in the aforementioned embodiments and will not be elaborated herein.

FIG9 is a schematic diagram of the bottom plate assembly of the fourth embodiment of the present invention, please refer to FIG9. 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 FIG1 for the key structure 10). 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. The 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. Similarly, the structure of the first hook 222c and its connection relationship with the supporting portion 211 can be referred to the aforementioned embodiment, and no further description is given here.

FIG. 10 is a schematic diagram of the bottom plate assembly of the fifth embodiment of the present invention, please refer to FIG. 10. The bottom plate assembly 20d of this embodiment also includes a lightweight body 21 and a reinforcing member 22d. Among them, the configuration of the lightweight body 21 is the same as that of the first embodiment, so its number 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 reinforcing member 22d can be set at the position where the first frame 111 (please refer to FIG. 1 or FIG. 2) of the connecting assembly 11 needs to be connected, so that the first frame 111 can be pivoted on 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 key structures 10. In addition, the structure of the first hook 222d and its connection relationship with the supporting portion 211 can be referred to the aforementioned embodiment, and will not be described in detail here.

FIG11 is a schematic diagram of the bottom plate assembly of the sixth embodiment of the present invention, please refer to FIG11. 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 FIG1, FIG3 and FIG5), but a supporting portion 211e is provided at the position of the original second hook 213. In other words, compared with the first embodiment, the number of supporting portions 211e of 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 supporting portion 211e is disposed on the side wall of the first hook 222e and the side wall of the third hook 225e respectively. The supporting portion 211e of this embodiment is disposed on the outer side wall of the first hook 222e and the outer side wall of the third hook 225e.

As in the above-mentioned embodiment, one end of the first frame 111 (please refer to FIG. 1 and FIG. 2 ) of the connecting assembly 11 is connected to the first hook 222e. In this embodiment, one end of the second frame 112 (please refer to FIG. 1 and FIG. 2 ) is connected to the third hook 225e. Preferably, one end of the first frame 111 is pivotally connected to the first hook 222e, and one end of the second frame 112 is movably connected to the third hook 225e. In this embodiment, the first frame 111 and the second frame 112 of the connecting assembly 11 are both connected to the hooks (i.e., the first hook 222e and the third hook 225e) on the stronger reinforcing member 22e.

In addition, the reinforcing member 22e of this embodiment corresponds to a single key structure 10. The reinforcing member 22e has a transverse and longitudinal connecting portion 224e to connect the fixing portion 221e close to the first hook 222e and the third hook 225e.

In summary, according to the keyboard of the present invention, the bottom plate assembly includes a lightweight body and at least one reinforcement member. The lightweight body includes at least one supporting portion, and the reinforcement member includes at least one first hook. The supporting portion is disposed on a side wall of the first hook, and the connecting assembly is assembled to the first hook. The first hook is a reinforcement member with high strength, which can achieve the effect of improving the bottom plate assembly. In addition, the supporting portion is disposed on the side wall of the first hook, which can increase the strength of the first hook, thereby improving the durability of the first hook.

It should be noted that the above embodiments are given for the purpose of illustration only, and the scope of rights claimed by the present invention should be based on the scope of the patent application, rather than being limited to the above embodiments.
