[0002] The existing key structure includes a key cap for the user to press. In order to provide a lifting function, the key structure usually includes a lifting mechanism, which is pivotally connected to the base plate and the key cap so that the key cap can be lifted relative to the base plate. However, in assembly, the base plate, the key cap and the lifting mechanism need to be individually configured with a plurality of pivot parts, resulting in a relatively complex structural design. Summary of the invention

[0003] The present invention relates to a key structure and a lifting mechanism thereof, which can improve the above-mentioned conventional problems.

[0004] One embodiment of the present invention provides a lifting mechanism. The lifting mechanism includes a first pivot member and a second pivot member. The first pivot member has a pivot hole and includes a first pivot portion. The second pivot member includes a pivot shaft and a second pivot portion. The pivot shaft is pivoted to the pivot hole, and the first pivot portion and the second pivot portion are used to pivot to the same slide slot.

[0005] Another embodiment of the present invention provides a key structure. The key structure includes a key cap, a carrier, a base, a reset member and a lifting mechanism. The base is disposed on the carrier. The reset member is disposed between the key cap and the carrier. The lifting mechanism pivots the base and the key cap. The lifting mechanism includes a first pivot member and a second pivot member. The first pivot member has a pivot hole and includes a first pivot portion. The second pivot member includes a pivot shaft and a second pivot portion. The pivot shaft is pivoted to the pivot hole, and the first pivot portion and the second pivot portion are used to pivot to the same slide groove.

[0006] It can be seen from the above scheme that the advantages of the present invention are:

[0007] The key structure of the present invention includes a key cap, a base and a lifting mechanism. The lifting mechanism includes a first pivot member and a second pivot member pivotally connected to each other. The first pivot member and the second pivot member can be pivotally connected to the same slide groove of the base. In this way, the assembly structure and assembly process of the lifting mechanism and the pair of members can be simplified.

[0074] Please refer to Figures 1A to 4B , Figure 1A-1B 1 is a three-dimensional diagram of a key structure 100 according to an embodiment of the present invention at different viewing angles. Figure 2A for Figure 1A An exploded view of the key structure 100 is shown in FIG. Figure 2Bfor Figure 1B An exploded view of the key structure 100 is shown in FIG. Figure 3A for Figure 1A An exploded view of the lifting mechanism 120, the base 130A and the base 130B, Figure 3B for Figure 1B An exploded view of the lifting mechanism 120, the base 130A and the base 130B, Figure 4A for Figure 1A The side view of the key structure 100 is shown in FIG. Figure 4B for Figure 1B A side view of the key structure 100.

[0075] like Figure 1A , 2A As shown in FIG. 3A , the key structure 100 includes a keycap 110, a lifting mechanism 120, at least one base (e.g., bases 130A and 130B), a reset member 140, a carrier 150, a limit member 160, and at least one fixing member 170. The bases 130A and 130B are disposed on the carrier 150. The reset member 140 is disposed between the keycap 110 and the carrier 150. The lifting mechanism 120 is pivotally connected to the base (130A and 130B) and the keycap 110. In this embodiment, the lifting mechanism 120 includes at least one first pivot member (e.g., a first pivot member 121A and a first pivot member 121B) and at least one second pivot member (e.g., a second pivot member 122A and a second pivot member 122B). In one embodiment, the combination of the first pivot member and the second pivot member is similar to a scissor mechanism, wherein the first pivot member can be referred to as an "external scissor" and the second pivot member can be referred to as an "internal scissor". The first pivot member 121A is similar or identical to the first pivot member 121B in structure, and the first pivot member 121A is used as an example for description below. The second pivot member 122A is similar or identical to the second pivot member 122B in structure, and the second pivot member 122A is used as an example for description below.

[0076] like Figure 1A , 2A As shown in Figures 3A and 4A, the first pivot member 121A has at least one pivot hole (e.g., pivot holes 121a1 and 121a2) and includes at least one first pivot portion (e.g., first pivot portions 1211A and 1211B). The second pivot member 122A includes at least one pivot shaft (e.g., pivot shafts 1221A and 1221B) and at least one second pivot portion (e.g., second pivot portions 1222A and 1222B). The pivot shafts 1221A and 1221B are pivotally connected to the pivot holes 121a1 and 121a2, respectively, and the first pivot portion 1211A and the second pivot portion 1222A are used to pivotally connect to the same slide slot, such as the same slide slot 130r1 of the base 130A. In this way, the assembly structure and assembly process of the lifting mechanism and the hand member can be simplified.

[0077] like Figure 2B As shown, the keycap 110 includes a body 111, at least one first keycap pivoting portion (e.g., first keycap pivoting portions 112A and 112B) and a triggering portion 113. The first keycap pivoting portions 112A and 112B are connected to the body 111. The keycap 110 has at least one first slide groove to pivotally connect the lifting mechanism 120. For example, the first keycap pivoting portion 112A has a first slide groove 112Ar, and the first keycap pivoting portion 112B has a first slide groove 112Br, wherein the first slide groove 112Ar can be pivotally connected to one of the first pivoting members 121A of the lifting mechanism 120, and the first slide groove 112Br can be pivotally connected to another first pivoting member 121B of the lifting mechanism 120. In addition, the triggering portion 113 is connected to the body 111, and the triggering portion 113 corresponds to the reset member 140 in position. In one embodiment, the trigger portion 113 may frequently abut against the restoring member 140 , which may reduce or even avoid impact noise (for example, when the keycap 110 is pressed).

[0078] In one embodiment, if the first pivot members 121A and 121B and the second pivot members 122A and 122B are made of the same material (e.g., insulating material), such as plastic, the noise generated during the relative movement of the first pivot members 121A and 121B and the second pivot members 122A and 122B can be reduced or avoided. Compared with metal, the impact noise of plastic is smaller.

[0079] like Figure 3A As shown, the first pivot member 121A further includes a first connecting rod 1212 and first pivot rods 1213A and 1213B disposed opposite to each other. The first connecting rod 1212 connects the first pivot rods 1213A and 1213B, and the first pivot portions 1211A and 1211B of the first pivot member 121A are disposed at the ends of the first pivot rod 1213A and the ends of the first pivot rod 1213B, respectively. In one embodiment, the first connecting rod 1212, the first pivot rod 1213A and the first pivot rod 1213B may form a U-shaped structure.

[0080] like Figure 3A As shown, the lifting mechanism 120 further includes a second connecting rod 123, which can connect the first pivot members 121A and 121B. In one embodiment, the second connecting rod 123, the first pivot member 121A and the first pivot member 121B can form an integrally formed pivot member (or called "outer shear"). Since the second connecting rod 123 connects the first pivot members 121A and 121B, the number of pivoting parts of the keycap 110 can be reduced. In addition, since the second connecting rod 123 connects the first pivot members 121A and 121B, the first pivot member 121A and the first pivot member 121B can be moved synchronously.

[0081] like Figure 3AAs shown, the second connecting rod 123 includes a recess 123r, wherein the recess 123r can surround the reset member 140. The recess 123r can avoid the reset member 140 to prevent the second connecting rod 123 from interfering with the reset member 140 during the rotation of the lifting mechanism 120 and the base. Figure 4A As shown, when the key cap 110 is in a released state (not pressed state), the recess 123r surrounds the reset member 140, and the second connecting rod 123 and the reset member 140 are spaced apart from each other, that is, they do not interfere with each other. Figure 4B As shown, when the keycap 110 is in a pressed state, the second connecting rod 123 is located above the reset member 140, but still maintains a distance from the reset member 140, that is, does not interfere with the reset member 140. Since the second connecting rod 123 and the reset member 140 are normally or frequently kept apart, during the rotation process of the lifting mechanism 120 and the base, they will not collide with each other and make noise.

[0082] like Figure 3A As shown, the second connecting rod 123 includes a first sub-rod 1231, a second sub-rod 1232, a third sub-rod 1233, a fourth sub-rod 1234, a fifth sub-rod 1235, a sixth sub-rod 1236 and a seventh sub-rod 1237. The first sub-rod 1231 and the second sub-rod 1232 are respectively connected to the first pivot member 121A and the first pivot member 121B, the third sub-rod 1233 is connected to the first sub-rod 1231 and the fifth sub-rod 1235, and the fourth sub-rod 1234 is connected to the second sub-rod 1232 and the fifth sub-rod 1235. The third sub-rod 1233, the fourth sub-rod 1234 and the fifth sub-rod 1235 can surround the aforementioned recess 123r. In one embodiment, the third sub-rod 1233, the fourth sub-rod 1234 and the fifth sub-rod 1235 can form a U-shaped structure.

[0083] like Figure 3A As shown, the sixth sub-rod 1236 connects the first sub-rod 1231 and the fifth sub-rod 1235, or connects the first sub-rod 1231 and the third sub-rod 1233, so as to increase the strength of the second connecting rod 123. The seventh sub-rod 1237 connects the second sub-rod 1232 and the fifth sub-rod 1235, or connects the second sub-rod 1232 and the fourth sub-rod 1234, so as to increase the strength of the second connecting rod 123.

[0084] like Figure 3A As shown, the lifting mechanism 120 further includes a second pivot rod 1223, and the second pivot rod 1223 has two opposite ends. The second pivot parts 1222A and 1222B are respectively configured at the two ends of the second pivot rod 1223, or the second pivot parts 1222A and 1222B are respectively the two ends of the second pivot rod 1223.

[0085] like Figure 3AAs shown, the second pivot member 122A further includes a third pivot rod 1224 having two opposite ends. The aforementioned pivot shafts 1221A and 1221B are respectively disposed at the two ends of the third pivot rod 1224, or the pivot shafts 1221A and 1221B are respectively the two ends of the third pivot rod 1224.

[0086] like Figure 3A As shown, the second pivot member 122A further includes at least one stopper (e.g., stopper 1225A and 1225B), which are respectively disposed adjacent to the pivot shafts 1221A and 1221B. The stopper 1225A can be stopped by the pivot rod 1213A, thereby preventing the third pivot rod 1224 from being separated from the pivot rod 1213A through the pivot hole 121a1. Similarly, the stopper 1225B can be stopped by the pivot rod 1213B, thereby preventing the third pivot rod 1224 from being separated from the pivot rod 1213A through the pivot hole 121a2. In addition, the stopper portions 1225A and 1225B are located between the pivot rods 1213A and 1213B, and are limited by the stopper portions 1213A and 1213B, so that the displacement of the second pivot member 122A between the pivot rods 1213A and 1213B (for example, along the Y-axis direction) can be reduced or eliminated. Further, in one embodiment, the gap between the stopper portion 1225A and the pivot rod 1213A is almost zero, and the gap between the stopper portion 1225B and the pivot rod 1213B is almost zero, so that the second pivot member 122A can be prevented from moving relative to the first pivot member 121A along the Y-axis direction, thereby reducing or even preventing the occurrence of impact noise.

[0087] like Figure 3A As shown, the second pivot member 122A further includes a third connecting rod 1226. The third connecting rod 1226 can connect the second pivot rod 1223 and the third pivot rod 1224. The third connecting rod 1226, the second pivot rod 1223 and the third pivot rod 1224 can form an "I"-shaped structure, but this is not used to limit the embodiment of the present invention.

[0088] like Figure 3A and 3B As shown, the first pivot member 121A further includes a third pivot portion 121A1, wherein the third pivot portion 121A1 is disposed on a pivot rod 1213A. The first pivot member 121A is pivotally connected to the keycap 110 by the third pivot portion 121A1, such as the first keycap pivot portion 112A of the keycap 110. Similarly, the first pivot member 121B further includes a third pivot portion 121B1, wherein the third pivot portion 121B1 is disposed on a pivot rod 1213A of the first pivot member 121B. The first pivot member 121B is pivotally connected to the keycap 110 by the third pivot portion 121B1, such as the first keycap pivot portion 112B of the keycap 110.

[0089] like Figure 2A and 3A As shown, the base 130A has slide grooves 130r1 and 130r2 ( Figure 3A The base 130A of the present invention does not have the slide groove 130r2, so it is marked on the base 130B), which is respectively pivotally connected to the corresponding first pivot portions 1211A and 1211B of the first pivot member 121A. In this embodiment, the first pivot portions 1211A and 1211B of the first pivot member 121A are not connected, so the flexibility of the pivot rods 1213A and 1213B can be increased, and the assembly of the first pivot portions 1211A and 1211B in the slide grooves 130r1 and 130r2 can be improved (the higher the flexibility, the easier it is to assemble). The base 130B has the same or similar structure as the base 130A, and will not be repeated here.

[0090] like Figure 2A and 3A As shown, the first pivoting portion 1211A of the first pivoting member 121A and the second pivoting portion 1222A of the second pivoting member 122A can be pivoted to the same slide slot 130r1 of the base 130A, and the first pivoting portion 1211B of the first pivoting member 121A and the second pivoting portion 1222B of the second pivoting member 122A can be pivoted to another slide slot 130r2 of the base 130A. A pivoting assembly (e.g., the first pivoting member 121A and the second pivoting member 122A) is pivoted to two opposite slide slots 130r1 and 130r2 of the base 130A at two pivot points, thereby increasing the movement stability of the pivoting assembly and the base 130A.

[0091] like Figure 3A As shown, the reset member 140 is, for example, a switch. The reset member 140 includes a body 141, a trigger portion 142, abutting portion 143 and at least one pin 144. The trigger portion 142 can be movably arranged on the body 141 along the Z-axis direction. Based on an external force acting on the trigger portion 142 along the -Z-axis direction, the trigger portion 142 can move relative to the body 141 along the -Z-axis direction until a circuit (not shown) in the reset member 140 is turned on. In addition, the trigger portion 142 can be elastically arranged on the body 141 along the Z-axis direction, so that based on the release of the aforementioned external force, the trigger portion 142 can be reset relative to the body 141 along the +Z-axis direction. In addition, the trigger portion 113 of the aforementioned keycap 110 can frequently abut against the trigger portion 142 of the reset member 140 to reduce or even avoid impact noise.

[0092] like Figure 1A As shown, the abutting portion 143 of the restoring member 140 can abut against the limiting member 160. In addition, the pin 144 of the restoring member 140 can contact or be inserted into the carrier 150 to be electrically connected to the carrier 150.

[0093] like Figure 3AAs shown, the carrier 150 is, for example, a circuit board, but this is not intended to limit the embodiment of the present invention. The stopper 160 has a first through hole 160a1, a second through hole 160a2, and a third through hole 160a3. The reset member 140 can pass through the first through hole 160a1 to be disposed on the carrier 150, the base 130A can pass through the second through hole 160a2 to be disposed on the carrier 150, and the base 130B can pass through the third through hole 160a3 (the third through hole 160a3 is shown in FIG. Figure 2A ) to be disposed on the carrier 150. In addition, the base 130A can be fixed between the limiting member 160 and the carrier 150. For example, the base 130A includes a supporting portion 130A1, and the limiting member 160 can press the supporting portion 130A1 to press the bases 130A and 130B on the carrier 150. Similarly, the base 130B includes a supporting portion 130B1, and the limiting member 160 can press the supporting portion 130B1 to press the base 130 on the carrier 150. In addition, the limiting member 160 further includes at least one fixing column 161, and the fixing member 170 can be combined with the fixing column 161 to fix the relative positions of the base (130A and 130B), the carrier 150 and the limiting member 160. In one embodiment, the fixing member 170 is, for example, a screw, and the fixing column 161 has, for example, a screw hole. The fixing member 170 is screwed into the screw hole of the fixing column 161 to fix the relative positions of the base ( 130A and 130B), the supporting member 150 and the limiting member 160 .

[0094] Please refer to Figures 5A to 6B , Figure 5A and 5B 2 is a three-dimensional diagram of a key structure 200 according to an embodiment of the present invention at different viewing angles. Fig. 6A for Figure 5A The exploded view of the key structure 200 is shown in FIG. Figure 6B for Figure 5B An exploded view of the key structure 200.

[0095] like Figure 5A and 6A As shown, the key structure 200 includes a keycap 110, a lifting mechanism 220, at least one base (e.g., bases 130A and 130B), a reset member 140, a carrier 150, a stop member 160, and at least one fixing member 170. The bases 130A and 130B are disposed on the carrier 150. The reset member 140 is disposed between the keycap 110 and the carrier 150. The lifting mechanism 120 is pivotally connected to the base (130A and 130B) and the keycap 110. The key structure 200 of this embodiment includes the same or similar technical features (e.g., structure and / or connection relationship) as the aforementioned key structure 100, and one of the differences is that the second connecting rod 223 of the key structure 200 is different from the second connecting rod 123 of the key structure 100 in structure.

[0096] like Figure 5A and 6A As shown, the second connecting rod 223 includes a first sub-rod 1231, a second sub-rod 1232, a third sub-rod 1233, a fourth sub-rod 1234 and a fifth sub-rod 1235. The first sub-rod 1231 and the second sub-rod 1232 are respectively connected to the first pivot member 121A and the first pivot member 121B, the third sub-rod 1233 connects the first sub-rod 1231 and the fifth sub-rod 1235, and the fourth sub-rod 1234 connects the second sub-rod 1232 and the fifth sub-rod 1235. The third sub-rod 1233, the fourth sub-rod 1234 and the fifth sub-rod 1235 surround the aforementioned recess 123r, and the recess 123r can surround the reset member 140. In one embodiment, the third sub-rod 1233, the fourth sub-rod 1234 and the fifth sub-rod 1235 can form a U-shaped structure. Different from the second connecting rod 123 of the key structure 100 , the second connecting rod 223 omits the sixth sub-rod 1236 and the seventh sub-rod 1237 .

[0097] Please refer to Figures 7A to 10 , Figures 7A-7B is a stereoscopic diagram of a key structure 300 according to another embodiment of the present invention at different viewing angles.
