In addition, well-known steps or elements are not described in detail to avoid causing unnecessary limitations to the present invention.

[0012] Please refer to Figures 1 to 2D , Figure 1 FIG1 is a top view of an electronic device 10 according to an embodiment of the present invention. Figure 2A for Figure 1 An exploded view of a key structure K1 of an electronic device, Figure 2B for Figure 1 A cross-sectional view of the key structure K1 along line 2B-2B', Figure 2C for Figure 1 A schematic diagram of the button structure K1 when the cover 150 is lifted. Figure 2D To follow Figure 2C Cross-sectional view along the 2D-2D' line.

[0013] In this embodiment, the electronic device 10 is described by taking a keyboard as an example, but the present invention is not limited thereto. The input structure of the present invention can be used for other electronic devices with input structures (such as buttons or keys), such as touchpads, mice, mobile phones, home appliances, power supplies, switches, etc.

[0014] Please refer to Figure 2A The key structure K1 includes a base plate 110, a flexible layer 120, a support member 130, a connector 140, and a cover 150. The base plate 110 and the support member 130 can be connected. The flexible layer 120 is disposed between the base plate 110 and the support member 130. The connector 140 is disposed between the cover 150 and the support member 130 and connects the cover 150 and the support member 130. The base plate 110 and the support member 130 can be combined, for example, by hooking or snapping, so as to fix the flexible layer 120 between the base plate 110 and the support member 130. Figure 2A and 2BAs shown, the flexible layer 120 is disposed on the first side of the support member 130, and the cover 150 is disposed on the second side of the support member 130 opposite to the first side. In some embodiments, the materials of the bottom plate 110, the support member 130, and the cover 150 may include plastics, metals, or other rigid (non-flexible) materials; the material of the flexible layer 120 may include elastic materials, such as rubber, silicone, or other suitable materials, and the material of the connecting member 140 may include metals or plastics, but the present invention is not limited thereto.

[0015] Please refer to Figure 1 , the electronic device 10 includes a plurality of single keys and a plurality of multi-keys. Since the length of the multi-key is greater than the length of the single key, the multi-key is prone to generate large deformations (such as large shaking or tilting) during pressing and generate large noises. The positions of the multi-keys are, for example, Figure 1 the positions shown in the key structures K1 to K9, but the embodiments of the present invention are not limited thereto. At least one of the key structures K1 to K9 of the present invention includes at least one buffer structure (described later), so the noise during pressing can be reduced. The key structure K1 is, for example, a blank key, and the key structure K1 will be taken as an example for description below. According to some embodiments, the electronic device 10 is a keyboard including a film, but the present invention is not limited thereto.

[0016] As Figure 2A shown, the flexible layer 120 includes a plurality of buffer structures, such as several first buffer structures 122A (see Figure 2A and 2B ), several second buffer structures 122B (see Figure 2A and 2D ), several third buffer structures 122C (see Figure 2A ) and an intermediate buffer structure 122D (see Figure 2A ). As shown in the top view shown in Figure 1 , the key structure K1 has a geometric center point CP (see Figure 1 ), and the key structure K1 has an intermediate region and a peripheral region adjacent to the intermediate region, wherein the intermediate region is closer to the geometric center point CP than the peripheral region. Since the noise generated when pressing the peripheral region of the key structure K1 is greater than the noise generated when pressing the intermediate region of the key structure K1, some of the buffer structures can be disposed in the peripheral region of the key structure K1, but the present invention is not limited thereto. Moreover, the structures of two of these buffer structures can be the same, similar, or different from each other, and can be adjusted according to actual needs.

[0017] In one embodiment, the electronic device 10 further includes a circuit layer disposed below the flexible layer 120, such as a thin film circuit layer, a flexible printed circuit board, a printed circuit board, or an FFC. Pressing the button structure K1 causes one of the protruding portions of the flexible layer 120 (such as the relatively middle buffer structure 122D) to be pressed and deformed (compressed), and triggers a switching element disposed corresponding to the buffer structure 122D in the underlying circuit layer. In some embodiments, the flexible layer 120 can be a thin film circuit layer, a flexible printed circuit board, or an FFC, and the setting positions of some of the buffer structures can be offset from the switching elements.

[0018] As Figures 2A to 2B shown, at least one of these buffer structures, such as the first buffer structure 122A, includes a body portion 122A1, a first protruding portion 122A2, and a second protruding portion 122A3. The first protruding portion 122A2 is connected to the body portion 122A1 and protrudes relative to the surface 122Au of the body portion 122A1. The second protruding portion 122A3 is connected to the body portion 122A1 and protrudes relative to the surface 122Au of the body portion 122A1. The second protruding portion 122A3 surrounds at least a portion of the outer side surface of the first buffer structure 122A. For example, the second protruding portion 122A3 continuously extends and surrounds the entire outer side surface of the first buffer structure 122A.

[0019] As Figures 2A to 2B shown, the first protruding portion 122A2 and the second protruding portion 122A3 of the first buffer structure 122A protrude toward the support member 130. The first protruding portion 122A2 and the second protruding portion 122A3 are separately disposed to allow a portion of the support member 130 (such as the first extension portion 1302) to enter the region between the first protruding portion 122A2 and the second protruding portion 122A3. Since the first buffer structure 122A has elasticity, when the cover body 150 or the connecting member 140 contacts the first buffer structure 122A, the first buffer structure 122A provides buffering or resilience. In one embodiment, the first protruding portion 122A2 of the first buffer structure 122A includes a hollow portion 122Aw (a non-solid structure), but the present invention is not limited thereto. In other embodiments, the first protruding portion 122A2 can be a solid structure. In addition, the hollow portion 122Aw of the foregoing first protruding portion 122A2 is, for example, an open space formed on the side of the first protruding portion 122A2 adjacent to the bottom plate 110 to correspond to the bottom plate 110. That is, the hollow portion 122Aw is located on the opposite side of the cover body 150. In addition, in some embodiments, the material of the flexible layer 120 can be waterproof.

[0020] As Figure 2BAs shown, the first protruding portion 122A2 and the second protruding portion 122A3 protrude towards the support member 130 along the first direction Z. The height H1 of the first protruding portion 122A2 in the first direction Z is greater than the height H2 of the main body portion 122A1 in the first direction Z, and the height H3 of the second protruding portion 122A3 in the first direction Z is greater than the height H2 of the main body portion 122A1 in the first direction Z. In this embodiment, the height H1 of the first protruding portion 122A2 in the first direction Z is greater than the height H3 of the second protruding portion 122A3 in the first direction Z. However, the present utility model is not limited thereto. In other embodiments, the height of the first protruding portion 122A2 in the first direction Z may be equal to or less than the height of the second protruding portion 122A3 in the first direction Z.

[0021] As Figure 2A and 2B shown, the first protruding portion 122A2 overlaps with the hole (e.g., 130HA) of the support member 130 in the first direction Z. The first protruding portion 122A2 protrudes towards the support member 140 corresponding to the hole (e.g., hole 130HA) of the support member 130. In some embodiments, the first protruding portion 122A2 extends into the hole 130HA, for example, extending to a height exceeding half of the height of the hole 130HA along the first direction Z; according to an embodiment, the height of the first protruding portion 122A2 protruding towards the support member 130 in the first direction Z does not exceed the top of the hole (e.g., hole 130HA, which can also be regarded as an opening). However, the present utility model is not limited thereto. In other embodiments, the first protruding portion 122A2 does not extend into the hole 130HA. In some embodiments, the second protruding portion 122A3 surrounds the hole 130HA and does not overlap with the hole 130HA in the first direction Z. The second protruding portion 122A3 of the first buffer structure 122A surrounds a part of the support member 130 (e.g., the first extension portion 1302) in a full-circumference manner, so as to avoid the leakage of the liquid flowing in from the hole 130HA downward, thus preventing the occurrence of a short circuit.

[0022] As Figure 2A and 2B shown, in the second direction X, the first protruding portion 122A2 and the second protruding portion 122A3 of the first buffer structure 122A overlap with a part of the support member 130 (e.g., the first extension portion 1302). The second direction X is perpendicular to the first direction Z, for example.

[0023] As Figure 2A and 2DAs shown, the structure of the second buffer structure 122B can be similar to that of the first buffer structure 122A, and also includes a main body portion 122B1, a first protrusion 122B2, and a second protrusion 122B3. One of the differences between the second buffer structure 122B and the first buffer structure 122A is that the height of the first protrusion 122B2 in the first direction Z is greater than the height of the first protrusion 122A2 in the first direction Z. Other identical or similar parts will not be described in detail. In addition, as Figure 2D shown, the first protrusion 122B2 of the second buffer structure 122B can pass through the hole (for example, hole 130HB) of the support member 130 and contact the connecting member 140. Similarly, the first protrusion 122B2 of the second buffer structure 122B includes a hollow portion 122Bw (a non-solid structure). The hollow portion 122Bw is, for example, on the side of the first protrusion 122B2 adjacent to the bottom plate 110 to form an open space corresponding to the bottom plate 110. In other embodiments, the first protrusion 122B2 can be a solid structure.

[0024] As Figures 2A to 2C shown, the first protrusions (122A2 and 122B2) overlap the connecting member 140 in the first direction Z. Part of the first protrusion (122A2) overlaps a part of the cover 150 (for example, the upper protrusion 1502) in the first direction Z, as Figure 2B shown. When pressing both sides (or edges) of the button structure K1, the first protrusion 122A2 can contact the upper protrusion 1502 of the cover 150, preventing the upper protrusion 1502 from directly hitting the support member 130 and reducing noise.

[0025] As Figure 2C shown, the first buffer structure 122A is disposed at positions P1 to P3, and the second buffer structure 122B is disposed at positions S1 and S2. However, the present invention is not limited thereto, and the buffer structure 122 can be disposed at any position where impact or shaking is likely to occur to reduce noise. Positions S1 and S2 are located on opposite sides of the button structure K1, and greater deformation and greater noise can be generated compared to the middle part of the button structure K1. In some embodiments, the first buffer structure 122A can be further disposed at positions L1 to L3 and / or L4, and the second buffer structure 122B can be further disposed at positions X1, X2, Y1, and / or Y2.

[0026] As Figure 2AAs shown, the third buffer structure 122C is a single solid protruding structure and does not have the structure of the first protruding portion 122A2, the body portion 122A1, and the second protruding portion 122A3 as shown in the first buffer structure 122A. Moreover, the height of the third buffer structure 122C in the first direction Z is greater than the height H2 of the body portion 122A1 in the first direction Z, less than the height H1 of the first protruding portion 122A2 in the first direction Z, and less than the height H3 of the second protruding portion 122A3 in the first direction Z. The middle buffer structure 122D corresponds to the center point CP (for the center point CP, refer to Figure 1 ), and has a protruding structure corresponding to the geometric center point CP. For example, the middle buffer structure 122D protrudes towards the support member 140 corresponding to the hole (e.g., hole 130HD) of the support member 130. The height of the middle buffer structure 122D in the first direction Z can be greater than the height H1 of the first protruding portion 122A2 in the first direction Z. The middle buffer structure 122D may include a hollow portion (non-solid structure). The hollow portion of the middle buffer structure 122D is, for example, on the side of the middle buffer structure 122D adjacent to the bottom plate 110 to form an open space corresponding to the bottom plate 110.

[0027] As Figures 2A to 2B shown, the support member 130 is disposed on the flexible layer 120. For example, the support member 130 is disposed on the surface 122Au facing the body portion 122A1. The support member 130 further includes a plurality of holes 130H (which can also be regarded as openings). The holes 130H may include a plurality of holes 130HA, a plurality of holes 130HB, a plurality of holes 130HC and 130HC', a hole 130HD, and other holes. The shapes and sizes of the holes 130HA, 130HB, 130HC and 130HC', and the hole 130HD may be different from each other. The hole 130HD corresponds to the geometric center point CP, for example, and the holes 130HA, 130HB, 130HC are farther from the geometric center point CP than the hole 130HD. According to some embodiments, the height of the protruding portion (e.g., the protruding portion formed by the middle buffer structure 122D protruding towards the support member 140) corresponding to the first opening (e.g., the hole 130HD) in the first direction Z is greater than the height of the protruding portion (e.g., the first protruding portion 122A2 of the first buffer structure 122A, the first protruding portion 122B2 of the second buffer structure 122B, or the protruding portion formed by the third buffer structure 122C protruding towards the support member 140) corresponding to the second opening (e.g., the holes 130HA, 130HB, 130HC, or 130HC') in the first direction Z.

[0028] As Figure 2BAs shown, the support member 130 further includes a plate portion 1301 and a plurality of first extension portions 1302. The first extension portions 1302 are connected to the plate portion 1301. The first extension portions 1302 protrude toward the main body portion 122A1 of the flexible layer 120 and form a part of a hole 130HA corresponding to one of the first buffer structures 122A. The first protrusion 122A2 is located in the hole (such as the hole 130HA, which can be regarded as an opening). The first protrusion 122A2 and the second protrusion 122A3 are respectively located on opposite sides of a first extension portion 1302. In some embodiments, the support member 130 includes a first extension portion 1302 and a second extension portion 1303 corresponding to a hole (such as the hole 130HC). The first extension portion 1302 and the second extension portion 1303 are connected to the plate portion 1301. The first extension portion 1302 protrudes toward the flexible layer 120 and surrounds to form a part of the hole 130HC, and the second extension portion 1303 protrudes in a direction away from the flexible layer 120 and surrounds to form another part of the hole 130HC. That is, the hole 130HA is surrounded by the first extension portion 1302, and the hole 130HC is surrounded by the first extension portion 1302 and the second extension portion 1303. The protruding directions of the first extension portion 1302 and the second extension portion 1303 are, for example, parallel to the first direction Z.

[0029] As Figures 2A to 2C shown, a part of the second extension portion 1303 may correspond to positions L1 to L4 as Figure 2C shown, for example, to form a card slot structure for supporting and fixing the connecting member 140.

[0030] As Figures 2A to 2C shown, the connecting member 140 is disposed on the support member 130. The connecting member 140 can be used to maintain the balance of the key structure K1 and has a structure similar to an inverted U shape in the top view. Since the connecting member 140 is prone to shaking and generating noise during the process of pressing the key structure K1, a buffer structure 122 (such as the second buffer structure 122B) can be disposed under the connecting member 140 to reduce the shaking of the connecting member 140 and thereby reduce noise. According to some embodiments, a part of the connecting member 140 is located directly above the first protrusion (122A2) or the second protrusion (122A3).

[0031] As Figure 2A and 2BAs shown, the cover 150 is disposed on the support member 130 and the connecting member 140. The cover 150 includes a third body portion 1501 and a plurality of upper protruding portions 1502. The upper protruding portions 1502 are connected to the third body portion 1501 and extend toward the support member 130. At least one of the upper protruding portions 1502 overlaps with the first protruding portion (122A2) of the buffer structure (e.g., buffer structure 122A) in the first direction Z corresponding to the hole (e.g., hole HA). The upper protruding portion 1502 is, for example, a hook structure (corresponding to the hole 130HA), a columnar structure (corresponding to the hole 130HC), a unilateral hook structure (corresponding to the hole 130HC’), or other suitable structures. The upper protruding portions 1502 with different structures can be used for engaging with corresponding structures or positioning. For example, the upper protruding portion 1502 of the hook structure corresponding to the hole 130HA can be used for engaging with the connecting member 140; the upper protruding portion 1502 of the columnar structure corresponding to the hole 130HC can be used for positioning in the hole 130HC; the upper protruding portion 1502 of the unilateral hook structure corresponding to the hole 130HC’ can be used for positioning in the hole 130HC’.

[0032] Figure 3 It is a cross-sectional view of the key structure K21 according to a comparative example of the present utility model. One of the differences between the key structure K21 and the key structure K1 is that the design of the flexible layer 220 is different from the design of the flexible layer 120, and the design of the support member 230 is different from the design of the support member 130. Other identical or similar parts will not be described in detail.

[0033] Please refer to Figure 2B and 3 , the buffer structure 222 in the flexible layer 220 is different from at least one of the buffer structures 122 (e.g., the first buffer structure 122A2 and the second buffer structure 122B2) in the flexible layer 120, and the positions of the support member 230 on the opposite sides corresponding to the key structure K21 (e.g., Figure 2C the positions S1 and S2 shown) are not provided with holes.

[0034] One of the differences between the buffer structure 222 and the first buffer structure 122A2 and the second buffer structure 122B2 is that the buffer structure 222 is a single solid protruding structure, rather than a structure with the middle part corresponding to the first protruding portion and the peripheral part corresponding to the second protruding portion. And the buffer structure 222 is not provided at the positions on the opposite sides of the key structure K21 (e.g., Figure 2C the positions S1 and S2 shown).

[0035] The support member 230 includes a plate portion 2301, a plurality of first extension portions 2302, and a plurality of second extension portions 2303. The first extension portions 2302 and the second extension portions 2303 are connected to the plate portion 2301. The structure of the plate portion 2301 is the same as or similar toFigure 2B the structure of the plate portion 1301 shown. The structure of the second extension portion 2303 is the same as or similar to Figure 2B the structure of the second extension portion 1303 shown. The structure of the first extension portion 2302 is similar to Figure 2B the structure of the first extension portion 1302 shown, with the difference that the first extension portion 2302 forms a closed structure at positions S1 and S2 without forming a hole.

[0036] In Figure 3 the comparative example shown, buffer structures are not provided at the positions on opposite sides of the key structure K21 (for example, Figure 2C the positions S1 and S2 shown). Therefore, as shown in Figures 2A to 2D the embodiment in the figure, compared with Figure 3 the comparative example shown, it can have lower noise (for example, reducing noise through the first protruding portions 122A2 or 122B2). Even if buffer structures 222 are provided at the positions on opposite sides of the key structure K21 (for example, Figure 2C the positions S1 and S2 shown) and holes are provided at the corresponding positions of the support member 230, since the buffer structures 222 do not extend to the first protruding portions in the holes, the buffering provided for the upper protruding portion 1502 is small, so the effect of reducing noise is not good. In addition, the buffer structures 222 do not include second protruding portions, and it is impossible to prevent dust or liquid from flowing downward through the holes, which may increase the risk of short circuit and cause malfunction of the key structure or the entire electronic device.

[0037] In summary, the present utility model provides an input structure. The input structure includes a flexible layer, and a support member, a connecting member, and a cover body sequentially arranged on the flexible layer. The flexible layer includes at least one buffer structure, and the buffer structure includes a first protruding portion and a second protruding portion protruding toward the support member. The first protruding portion corresponds to the middle part of the buffer structure, and the second protruding portion corresponds to the peripheral part of the buffer structure. When the cover body or the connecting member is pressed by a user and contacts the first protruding portion, the first protruding portion can provide buffering to reduce noise. The second protruding portion can prevent liquid from leaking downward and prevent the occurrence of short circuit.

[0038] In conclusion, although the present utility model has been disclosed as above with embodiments, it is not intended to limit the present utility model. Those skilled in the art in the technical field to which the present utility model belongs can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to that defined by the appended claims.
