[0079] Figure 1 This is a schematic diagram of an input device according to an embodiment of the present invention. Figure 2A yes Figure 1 A schematic diagram of the button structure. Figure 2BShow Figure 2A The keycaps and scissor-switch components of the key structure are actuated. To clearly illustrate the structure of key structure 100, Figure 2A and Figure 2B The keycap 110 is shown in perspective. Please refer to... Figures 1 to 2B In this embodiment, the input device 10 is, for example, a keyboard. The input device 10 includes a key structure 100 and a housing 200. The key structure 100 consists of long keys, such as a space bar, and is disposed within the housing 200. The key structure 100 includes keycaps 110, scissor-switch components 120, and a base plate 130. The user can press the keycaps 110 and scissor-switch components 120 to engage / disengage them as follows: Figure 2A Move to the position shown. Figure 2B The location shown.

[0080] Figure 3A and Figure 3B They are Figure 2A and Figure 2B A side view of the button structure. Figure 4 yes Figure 3A The top view of the button structure. For details, please refer to... Figures 2A to 4 In this embodiment, the keycap 110 includes a first long side 111 extending along a first direction D1 and a second long side 112 opposite to the first long side 111. The scissor-switch assembly 120 includes a first scissor-switch leg 121 and a second scissor-switch leg 122. The first scissor-switch leg 121 includes a first long side 1211 extending along the first direction D1 and a plurality of first protrusions 1212 protruding from the first long side 1211 toward a second direction D2. The first long side 1211 is movably connected to the first long side 111 of the keycap 110. The second scissor-switch leg 122 includes a second long side 1221 extending along the first direction D1 and a plurality of second protrusions 1222 protruding from the second long side 1221 toward a second direction D2. The second long side 1221 is movably connected to the second long side 112 of the keycap 110. The plurality of first protrusions 1212 and the plurality of second protrusions 1222 are arranged adjacent to each other along the first direction D1 and are pivotally connected to each other. The second direction D2 is perpendicular to the first direction D1. Multiple first protrusions 1212 and multiple second protrusions 1222 are movably connected to the base plate 130.

[0081] It is worth mentioning that, in this invention, the first scissor-switch leg 121 has multiple first protrusions 1212 protruding relative to the first long side 1211, and the second scissor-switch leg 122 has multiple second protrusions 1222 protruding relative to the second long side 1221. The first scissor-switch leg 121 and the second scissor-switch leg 122 are connected to the keycap 110 via the first long side 1211 and the second long side 1221, and are pivotally connected to each other via the first protrusions 1212 and the second protrusions 1222. When the keycap 110 is pressed and descends, the first scissor-switch leg 121 and the second scissor-switch leg 122 can move synchronously relative to the keycap 110 and the base plate 130. Accordingly, the input device 10 and the key structure 100 of this invention, through the above configuration, can reduce noise during use and assembly time.

[0082] In this embodiment, the number of first protrusions 1212 is shown to be four and the number of second protrusions 1222 is shown to be six. However, the present invention does not limit the number of first protrusions 1212 and second protrusions 1222. Users can adjust them according to the length of different button structures.

[0083] The structure of the scissor-leg assembly 120 in this embodiment is described in detail below.

[0084] Figure 5A and Figure 5B yes Figure 4 The button structure is shown in exploded view from different angles. Please refer to the following: Figure 5A and Figure 5B The plurality of first protrusions 1212 include a pivot 1212a extending along a first direction D1, and a plurality of second protrusions 1222 include a pivot groove 1222a corresponding to the pivot 1212a. A receiving space S1 is provided between adjacent pairs of the plurality of second protrusions 1222, and each first protrusion 1212 is located within its corresponding receiving space S1. By connecting the pivot 1212a to the pivot groove 1222a, the first scissor legs 121 and the second scissor legs 122 are adapted to rotate along a rotation axis R parallel to the first direction D1. Accordingly, the scissor leg assembly 120 of this embodiment can rotate relative to each other through the above configuration. In other embodiments, the pivot may also be provided in the second protrusion, and the pivot groove may also be provided in the first protrusion; the present invention does not limit the arrangement and position of the pivot structure between the two.

[0085] Please refer to Figure 4Preferably, the first scissor-switch leg 121 further includes a first reinforcing portion 1213 extending from the first long side 1211 in the second direction D2, and the second scissor-switch leg 122 further includes a second reinforcing portion 1223 extending from the second long side 1221 in the second direction D2. The first reinforcing portion 1213 and the second reinforcing portion 1223 correspond to each other and are located between two of the plurality of second protrusions 1222. Accordingly, the first scissor-switch leg 121 and the second scissor-switch leg 122 of this embodiment can have strong structural strength, and when the user presses the corner of the button structure 100, the pressing force can still be transmitted to the center of the button structure 100.

[0086] Please refer to Figure 4 Preferably, the first reinforcing part 1213 has a first extension length L1 in the second direction D2 that is shorter than each of the first protrusions 1212, and the second reinforcing part 1223 has a second extension length L2 in the second direction D2 that is shorter than the plurality of second protrusions 1222, so that there is a gap between the first reinforcing part 1213 and the second reinforcing part 1223, and the two will not interfere with each other during operation. At the same time, the shorter extension lengths of the first reinforcing part 1213 and the second reinforcing part 1223 can prevent them from colliding with the component below.

[0087] In this embodiment, the first scissor legs 121 and the second scissor legs 122 are made of plastic, which can further reduce the noise during use and also reduce the carbon footprint, cost and overall weight. However, this utility model does not limit the material of the first scissor legs 121 and the second scissor legs 122.

[0088] Please refer to Figure 3A Preferably, the first thickness T1 of the first scissor leg 121 is approximately the same as the second thickness T2 of the second scissor leg 122, so that the first scissor leg 121 and the second scissor leg 122 have better overall structural strength when they are combined, and when the button structure 100 is pressed ( Figure 3B The keycaps 110 can be stored together, allowing for a greater range of motion.

[0089] Figure 5C yes Figure 4 The key structure is shown in a cross-sectional view along line AA. Please refer to... Figure 5C Preferably, the thickness T3 of the first reinforcing portion 1213 is less than the thickness T4 of the first protrusion 1212 and / or the thickness T5 of the second reinforcing portion 1223 is less than the thickness T6 of the second protrusion 1222. In this way, the scissor-leg assembly 120 not only provides stable force transmission but also reduces overall weight. Please refer to... Figure 4The length L4 of the second scissor pin 122 is greater than the length L3 of the first scissor pin 121. In other embodiments, the button structure 100 may also have the length L3 of the first scissor pin 121 greater than the length L4 of the second scissor pin 122. This utility model does not limit the lengths of the first scissor pin 121 and the second scissor pin 122.

[0090] The connection structure between the keycap 110 and the scissor-switch assembly 120 in this embodiment is described in detail below.

[0091] Please refer to Figure 5B The keycap 110 includes a pivot 113 and a slider 114. The pivot 113 is located near the first long side 111, and the slider 114 is located near the second long side 112. The first long side 1211 of the first scissor-switch leg 121 is connected to the pivot 113, and the second long side 1221 of the second scissor-switch leg 122 is movably connected to the slider 114. The second long side 1221 can move in the slider 114 in the second direction D2, so that the scissor-switch assembly 120 can operate smoothly when the keycap 110 is pressed. Preferably, the slider 114 is a hook-type groove. This invention does not limit the form of the pivot 113 and the slider 114, as long as they can be used to rotate the scissor-switch assembly 120 and move in the second direction D2.

[0092] The connection structure between the scissor-foot assembly 120 and the base plate 130 in this embodiment is described in detail below.

[0093] Please refer to Figure 4 and Figure 5A The base plate 130 includes a plurality of latching portions 131, which extend from the base plate 130 toward the keycap 110 and have bent portions 1311 extending in the second direction D2. The ends of a plurality of first protrusions 1212 and a plurality of second protrusions 1222 are provided with retaining pins SH, which are engaged with the base plate 130 via the plurality of latching portions 131. Figure 5A The dashed lines indicate the corresponding locking pins (SH) of the hook portions 131 on both sides. At least one of the hook portions 131 has a bent portion 1311 that points in a different direction than the other bent portions 1311. Preferably, the bent portion 1311 of the hook portion 131 that engages the first protrusion 1212 has a different direction than the bent portion 1311 of the hook portion 131 that engages the second protrusion 1222 (for example, such as...). Figure 5AThe rightmost hook portion 131 shown is used to engage the second protrusion 1222, with its bent portion 1311 oriented in the direction of paper injection. The second hook portion 131 from the right is used to engage the first protrusion 1212, with its bent portion 1311 oriented in the direction of paper ejection, thus reducing the possibility of detachment from the base plate 130. The base plate 130 has at least one opening 132, and the hook portions 131 can be disposed adjacent to the opening 132, allowing the ends of the first protrusion 1212 and the second protrusion 1222 to move within the opening 132, thereby reducing the size of the button structure 100 in the mounting direction. Preferably, the hook portion 131 is integrally formed with the base plate 130, and the hook portion 131 is formed by bending a portion of the base plate 130 at the opening 132. In other embodiments, the hook portion 131 can be a separate component disposed on the base plate 130. The scissor-leg assembly 120 can be securely connected to the base plate 130 via the hook portion 131.

[0094] Please refer to Figure 4 and Figure 5A Preferably, at least one of the plurality of first protrusions 1212 in this embodiment has an opening 1212b. In this embodiment, as... Figure 4 The rightmost and leftmost first protrusions 1212 shown have openings 1212b. The base plate 130 has a stop 133 extending toward the keycap 110, at least a portion of which is located in the opening 1212b. Accordingly, the key structure 100 of this embodiment, through the configuration of the opening 1212b and the stop 133, can further prevent the scissor-switch assembly 120 from falling off between the keycap 110 and the base plate 130. Preferably, one side of the stop 133 has a bevel 1331 to avoid interference with the first protrusion 1212 during operation. In this embodiment, the opening 1212b is rectangular, but this is not a limitation of the present invention. Furthermore, in other embodiments, the opening may also be provided in at least one of the plurality of second protrusions 1222, and this is not a limitation of the present invention either.

[0095] Please refer to Figure 5A The key structure 100 also includes a diaphragm 140, which is disposed between the base plate 130 and the keycap 110. The diaphragm 140 has at least one through hole 141 for the hook portion 131 to pass through and connect with the key axis SH. Figure 5AThe diagram shows four perforations 141, allowing the corresponding hook portion 131, or even multiple first protrusions 1212 and multiple second protrusions 1222, to pass through the corresponding perforations 141. The areas of the diaphragm 140 without perforations 141 can be used for circuit layout or to house other components, such as switches or elastic elements 150, or to prevent components such as the first reinforcing part 1213 and the second reinforcing part 1223 from directly contacting the base plate 130, thereby reducing noise during use. Accordingly, the position and number of perforations 141 on the diaphragm 140 can be designed according to the needs of circuit and component layout. In other embodiments, the circuitry can be arranged on the base plate 130.

[0096] Please refer to Figure 4 and Figure 5A The button structure 100 also includes an elastic element 150. The two closest to the center of the plurality of first protrusions 1212, together with the second long side 1221, surround an elastic element receiving space S2. The elastic element 150 is disposed between the base plate 130 and the keycap 110 and is located within the elastic element receiving space S2. Through the configuration of the elastic element 150, the button structure 100 of this embodiment allows the scissor-switch assembly 120 to... Figure 2B The pressed position shown is reset to as follows: Figure 2A The free position shown.

[0097] Figure 6 This is a schematic diagram of a button structure according to another embodiment of the present invention. Please refer to it. Figure 6 The difference between the button structure 100a in this embodiment and the button structure 100 in the above embodiment is that the elastic element accommodating space S2 in this embodiment can be formed by a through hole provided thereon by either the first protrusion 1212 or the second protrusion 1222 near the center. Furthermore, the opening 1212b in this embodiment is square in shape. Figure 6 The remaining configuration and operation of the button structure 100a in the illustrated embodiment are the same as or similar to those of the button structure 100 in the foregoing embodiment, and will not be described again here.

[0098] Figure 7 This is a schematic diagram of a button structure according to another embodiment of the present invention. Please refer to it. Figure 7 The difference between the button structure 100b in this embodiment and the button structure 100 in the above embodiment is that the button structure 100b in this embodiment further includes a light-emitting element 160, which is disposed on the base plate 130. In this embodiment, the length of one of the first scissor legs 121 and the second scissor legs 122 is designed to be greater than the length of the other, so that there is space next to the other to arrange the light-emitting element 160. Figure 7 The length L4 of the second scissor leg 122 is greater than the length L3 of the first scissor leg 121, so that the light-emitting element 160 is located in one of the plurality of second protrusions 1222 (e.g., Figure 7Next to the rightmost one shown. Accordingly, the button structure 100b of this embodiment can be used in the dark by means of the configuration of the light-emitting element 160. In other embodiments, the button structure 100 may also have a first scissor leg 121 with a length L3 greater than the second scissor leg 122 with a length L4, so that the light-emitting element 160 is located next to one of the plurality of first protrusions 1212.

[0099] Furthermore, this embodiment reduces the width of several of the first protrusions 1212 and reduces the number of second protrusions 1222 to four, making this embodiment applicable to button structures 100b with shorter lengths in the first direction D1. Accordingly, in this embodiment, the first reinforcing portion 1213 and the second reinforcing portion 1223 are located between a first protrusion 1212 and a second protrusion 1222. Figure 7 The remaining configuration and operation of the button structure 100b in the illustrated embodiment are the same as or similar to those of the button structure 100 in the foregoing embodiment, and will not be described again here.

[0100] In summary, the input device and key structure of this utility model include a keycap, a scissor-switch assembly, and a base plate. The first scissor-switch includes a first long side and a plurality of first protrusions extending from the first long side; the second scissor-switch includes a second long side and a plurality of second protrusions extending from the second long side. The first and second scissor-switch are connected to the keycap via the first and second long sides and pivotally connected to each other via the first and second protrusions. When the keycap is pressed and descends, the first and second scissor-switch can move synchronously relative to the base plate. Therefore, the input device and key structure of this utility model can reduce noise during use and the number of parts and time required for assembly.

[0101] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it.
