The adjusting member 160 is provided corresponding to the positioning part 151, and the adjusting member 160 can be moved to drive the positioning part 151 to move, so that the hand-elastic member 150 has a first deformation or a second deformation, thereby changing the key shaft 130 toward the base 110 and driving The portion 131 passes the required pressing force of the extension arm 152.

In addition, the key structure 10 may further include an electrode module 170, a light source unit 180, a circuit board, a bottom plate, and the like. The electrode module 170 is disposed on the base 110 corresponding to the key shaft 130 as a switch component. When the key shaft 130 moves toward the base 110, the electrode module 170 is triggered to generate a trigger signal. The light source unit 180 includes a light source 181 and a light guide column 182 for generating light to form a light-emitting button.

Specifically, the base 110 may be disposed on a bottom plate or a printed circuit board. In this embodiment, the base 110 is disposed on the circuit board 190 as an example, but not limited thereto. In other embodiments, when the base 110 is disposed on the bottom plate, the circuit board may be selectively disposed above or below the bottom plate according to actual applications. In one embodiment, the base 110 and the circuit board 190 are preferably positioned by a positioning mechanism. For example, the base 110 may have a positioning post 112, and the circuit board 190 may have a socket 191 corresponding to the positioning post 112, so that the base 110 can be fixed to the circuit board 190 by inserting the positioning post 112 into the socket 191, but not Limited. In other embodiments, the positions of the positioning posts and the jacks can be interchanged, or the base 110 can be positioned on the lower board (such as the circuit board 190 or the bottom board) by other methods such as locking, adhering, and bearing.

The base 110 is preferably a lower housing extending in the X-axis, Y-axis, and Z-axis directions, and the cover 120 is an upper housing corresponding to the base 110. The base 110 is preferably combined with the cover 120 to form a housing with an accommodating space for accommodating the recovery unit 140, the handle elastic member 150, the electrode module 170, the light source unit 180 and the like. For example, the base 110 may have a buckle portion 119, and the cover 120 has a buckle hole portion 121, so that the base 110 and the cover body 120 are buckled with each other by the buckle portion 119 and the buckle hole portion 121 along the Z-axis direction.

The cover 120 has an opening 122 corresponding to the top shape of the key shaft 130, so that the key shaft 130 can be movably penetrated through the opening 122 of the cover 120 from below the cover 120, and the top of the key shaft 130 protrudes from the opening 122. The key shaft 130 preferably has an actuating portion 131, an actuating portion 132, a limiting portion 133, and an engaging portion 134. For example, the key shaft 130 is preferably a cylindrical cap, the actuating portion 131, the actuating portion 132 and the limiting portion 133 are preferably provided along the periphery of the lower end of the key shaft 130, and the engaging portion 134 is preferably provided on the key shaft 130 top.

Specifically, the actuating portion 131 includes a protrusion extending downward, and the protrusion has a lower contact surface 1311, an upper contact surface 1312, and a vertex 1313, and the vertex 1313 is located between the lower contact surface 1311 and the upper contact surface 1312. For example, the convex block may be an angular block, so that the lower contact surface 1311 and the upper contact surface 1312 preferably extend diagonally toward each other and are connected to the vertex or 1313, that is, the vertex 1313 faces the lower contact surface 1311 and the upper contact surface 1312 The outside (for example, Y-axis direction) protrudes. The actuating portion 132 is provided corresponding to the electrode module 170, and the actuating portion 132 is preferably in the form of a bump (such as an angular block) for selectively triggering the electrode module 170 to generate a trigger signal. The limiting portion 133 is preferably a cylinder protruding radially from both sides of the key shaft 130 so that the distance between the two cylinders is greater than the diameter of the opening 122 of the cover 120, thereby preventing the key shaft 130 from moving relative to the base 110 When detached from the cover 120. The engaging portion 134 may be, for example, a cross-shaped engaging post formed on the top of the key shaft 130 for engaging with a key cap (not shown), but not limited thereto. In other embodiments, the engaging portion 134 may be in other forms (such as an engaging hole) to engage with the keycap.

Hereinafter, referring to FIGS. 2A to 2C, the arrangement of each element on the base 110 will be described in detail. In this embodiment, the recovery unit 140 is preferably a spring, and the base 110 has a positioning portion 113 so that the recovery unit 140 can be positioned on the positioning portion 113. For example, the positioning portion 113 is an annular wall extending from the bottom of the base 110 toward the cover 120, so that one end of the spring (ie, the recovery unit 140) can be sleeved on the annular wall, and the other end of the spring abuts the key shaft 130 The bottom surface of the key shaft 130 protrudes from the opening 122 of the cover 120. Thereby, when the key cap is pressed to move the key shaft 130 toward the base 110, the key shaft 130 compresses the spring, and when the pressing force is released, the spring can provide an elastic restoring force to move the key shaft 130 away from the base 110 to the position before pressing position. Furthermore, corresponding to the light source unit 180, the base 110 preferably has an accommodating portion 1131. For example, the accommodating portion 1131 may be a space surrounded by the annular wall as the positioning portion 113 for accommodating the light guide column 182. That is, the light guide column 182 is disposed inside the positioning portion 113, and the spring is sheathed outside the positioning portion 113. Furthermore, the bottom of the base 110 corresponding to the accommodating portion 1131 preferably forms an opening, and the light source 181 is correspondingly disposed below the light guide post 182 to emit light toward the light guide post 182. In this embodiment, the light source 181 is preferably a light emitting diode, but it is not limited thereto.

The electrode module 170 includes a first electrode sheet 171 and a second electrode sheet 172, and the first electrode sheet 171 and the second electrode sheet 172 are respectively inserted into the base 110 correspondingly, and then electrically connected to the circuit board 190. For example, the base 110 has a first electrode hole 114 and a second electrode hole 115, and the circuit board 190 has a first contact hole 192 and a second contact hole 193, respectively corresponding to the first electrode hole 114 and the second electrode hole 115. Specifically, the first electrode piece 171 and the second electrode piece 172 are preferably inserted into the first electrode hole 114 and the second electrode hole 115 respectively, and then protrude below the base 110 and are connected to the first contact hole 192 and the second contact hole 193 Electrical connection, but not limited to this. In other embodiments, the circuit board 190 may not have a contact hole, and the first electrode piece 171 and the second electrode piece 172 may be electrically connected to the surface contact area of the circuit board 190. In this embodiment, the first electrode sheet 171 preferably abuts the inner wall surface of the base 110, and the second electrode sheet 172 is disposed corresponding to the first electrode sheet 171. The first electrode sheet 171 has an elastic portion 1711, and the elastic portion 1711 is disposed corresponding to the actuation portion 132 of the key shaft 130, so that the first electrode sheet 171 and the second electrode sheet 712 are selectively contacted according to the movement of the actuation portion 132, and Triggered to generate a trigger signal. For example, when the key structure 10 is in the unpressed position, the apex of the bump of the actuating portion 132 pushes outward against the elastic portion 1711 away from the second electrode sheet 172, so that the first electrode sheet 171 and the second electrode sheet 172 are not in contact Or it is not turned on, and no trigger signal is generated. When the key shaft 130 is pressed and moves toward the base 110, the key shaft 130 drives the actuating portion 132 to move downward so that the apex of the bump passes over the elastic portion 1711, so that the elastic portion 1711 rebounds toward the second electrode sheet 172, thereby causing the first An electrode sheet 171 contacts or conducts with the second electrode sheet 172 to generate a trigger signal.

It should be noted here that although the key structure 10 takes the electrode module 170 as a switch component for example, it is not limited thereto. In other embodiments, the key structure 10 can selectively generate a trigger signal in response to the movement of the key shaft 130 through other types of switch components. For example, the key structure 10 may include a light emitter and a light receiver electrically connected to the circuit board 190 as switching components (ie, optical axis switches), so that the key structure 10 can change light when the key shaft 130 moves toward the base 110 The amount of light received by the receiver from the optical transmitter generates a trigger signal.

In this embodiment, the elastic handle 150 is preferably a torsion spring. The positioning portion 151 and the extending arm 152 of the handle elastic member 150 extend from opposite ends of the torsion spring, and there is an angle between the extending direction of the positioning portion 151 and the extending direction of the extending arm 152, and the included angle is preferably not greater than 120 degrees. For example, the positioning portion 151 and the extension arm 152 are rods extending from opposite ends of the torsion spring body 153, and the angle between the extension directions of the two rods is preferably not greater than 120 degrees.

As shown in the figure, corresponding to the elastic handle 150, the base 110 has a positioning hole 111 for inserting the positioning portion 151 to position the elastic handle 150. In one embodiment, the positioning hole 111 is preferably an elongated hole formed at the bottom of the base 110 along the X-axis direction to allow the positioning portion 151 of the handle elastic 150 to be displaced in the positioning hole 111. Furthermore, corresponding to the positioning hole 111, the base 110 further has an opening 116 for the adjustment member 160 to be provided. For example, the opening 116 is preferably a notch partially hollowed from the side wall adjacent to the positioning hole 111 toward the bottom of the base 110, and the opening 116 communicates with the positioning hole 111, so that when the adjustment member 160 moves in the opening 116, The positioning portion 151 can be pushed to move along the positioning hole 111, but not limited to this. In another embodiment, the opening 116 may be an opening formed at the bottom of the base 110 and communicating with the positioning hole 111. Furthermore, the base 110 preferably further has an accommodating area 117 for setting the torsion spring body 153 of the handle elastic member 150. For example, the accommodating area 117 may be a space partitioned by the base 110 using a plurality of wall areas to limit the movement range of the elastic handle 150. When the adjusting member 160 pushes the positioning portion 151, the torsion spring body 153 can be confined in the accommodating area 117, so that the handle elastic member 150 is deformed differently. Furthermore, the base 110 may further have an impact portion 118 for the extension arm 152 to strike to generate a sound. For example, the impact portion 118 may be a convex wall protruding from the bottom of the base 110 toward the cover 120, and the wall surface of the convex wall facing the extension arm 152 is the impact surface 1181. When the feel elastic member 150 is disposed on the base 110, the positioning portion 151 is inserted into the positioning hole 111, the torsion spring body 153 is positioned in the accommodating area 117, and the extending arm 152 extends through the moving path of the actuating portion 131 of the key shaft 130. That is, the positioning portion 151 is substantially inserted into the positioning hole 111 in the Z-axis direction and is at least partially located in the opening portion 116, and the extending arm 152 substantially extends below the actuating portion 131 in the X-axis direction.

In one embodiment, the adjusting member 160 is preferably provided corresponding to the handle elastic member 150, and the adjusting member 160 preferably includes an adjusting rod 161 and a connecting portion 162. The connecting portion 162 is provided below the circuit board 190, and the adjusting lever 161 is connected to the connecting portion 162 and protrudes in the direction of the cover 120 (for example, the Z-axis direction). For example, the circuit board 190 has a moving groove 194 corresponding to the opening 116, and the adjusting rod 161 is inserted into the moving groove 194 upward from below the circuit board 190, and then extends into the opening 116 to correspond to the positioning portion 151 protruding from below the positioning hole 111 . When the adjusting member 160 moves, the adjusting rod 161 can drive the positioning portion 111 to move, so that the feel-elastic member 150 has different deformations. In one embodiment, the adjusting rod 161 preferably has a limiting groove 1611, and the limiting groove 1611 is preferably disposed along the length of the adjusting rod 161 (eg, Z-axis direction) to correspond to the long axis direction of the positioning portion 151. For example, the limiting groove 1611 may be an open channel opened on the wall surface of the adjusting rod 161 facing the positioning portion 151 (for example, parallel to the XZ plane), for the positioning portion 151 to be inserted into the positioning hole 111 and at least partially accommodated in the limiting portion The positioning groove 1611 further strengthens the coordinated positioning of the adjustment rod 161 and the positioning part 151, and reduces the chance of the adjustment rod 161 slipping off when the positioning part 151 moves, but it is not limited to this. In other embodiments, the limiting groove 1611 may be a hole formed downward from the top surface of the adjustment rod 161 (for example, parallel to the XY plane) for the positioning portion 151 to be inserted into the adjustment rod 161. In addition, according to actual application, the adjusting rod 161 may not have the limiting groove 1611, but the wall surface of the adjusting rod 161 abuts the positioning portion 151.

3A and 3B, the operation of the key structure 10 of the present invention using the adjusting member 160 to adjust the feel of pressing is described. FIG. 3A and FIG. 3B are schematic cross-sectional views along the tangent line AA of FIG. 1C. As shown in FIG. 3A, when the feel elastic member 150 is disposed on the base 110, the torsion spring body 153 is located in the accommodating area 117, the positioning portion 151 is downwardly inserted into the positioning hole 111 and at least partially abuts the adjustment rod 161 (eg, at least partially inserted The limiting groove 1611), and the extending arm 152 extends below the actuating portion 131. In this embodiment, the adjusting member 160 is preferably movable toward the extending direction of the extending arm 152 (for example, the X-axis direction), so as to change the deformation of the handle elastic member 150, and thereby change the preload of the handle elastic member 150. As shown in FIG. 3B, when the adjustment lever 161 moves in the X-axis direction, the adjustment lever 161 drives the positioning portion 151 in the positioning hole 111 to move in the X-axis direction, so that the positioning portion 151 and the extension arm 152 are relative to the torsion spring body 153 The position changes (that is, produces different deformations), that is, the preload of the torsion spring changes, which can change the actuation relationship between the actuating portion 131 and the handle elastic member 150, so as to provide different pressing feels, such as different pressing pressures, and frustrating feelings , Linear feel. In other words, when the adjustment member 160 moves different distances in the X-axis direction, the torsion spring can have different preloads, or the position of the extension arm 152 relative to the moving path of the actuating portion 131 can be different to provide different pressing Feel.

Hereinafter, referring to the drawings, the moving position of the adjusting member 160 in the X-axis direction and the corresponding hand feeling provided by the key structure 10 will be described in detail. 4A and 4B are a top view of the key structure 10 of FIG. 1A in a first state and a cross-sectional view along a tangent line BB. As shown in FIGS. 4A and 4B, when the key structure 10 is in the first state, the adjusting member 160 abuts the positioning portion 151 and is located at the first position in the X-axis direction. At this time, the feel-elastic member 150 has a first deformation, so that the pressing force required for the key shaft 130 to move toward the base 110 and drive the moving portion 131 over the extension arm 152 is the first pressing force. For example, the first position may be the position of the adjusting member 160 when the key structure 10 is in the preset state, so that the first pressing force is the preset pressing force. When the adjusting member 160 is located at the first position, the extension arm 152 preferably moves downward through the actuating portion 131 (ie, the movement path is parallel to the Z-axis direction), and the extension arm 152 is located at the first position relative to the movement path. When the adjusting member 160 is in the first position, when the first pressing force is applied to the key shaft 130, the key shaft 130 is moved toward the base 110 and the moving part 131 is moved, and the extension arm 152 first moves downward and slides along the lower contact surface 1311 After reaching the apex 1313, and after passing the apex 1313, it moves upward to strike the base 110 or the cover 120 to generate a sound (for example, a first sound). In other words, when the feel elastic member 150 has the first deformation and presses the key shaft 130, the extension arm 152 first slides along the lower contact surface 1311 to the apex 1313, and the extension arm 152 reaches the vertex 1313 after sliding the first contact surface 1311 a first distance, extending After the arm 152 crosses the apex 1313 later, it moves away from the bump and moves upward. It should be noted here that when the extension arm 152 reaches the apex 1313, the impact surface of the extension arm 152 and the base 110 or the cover body 120 has a first utterance distance, and the extension arm 152 strikes the impact surface to generate a first sound. In this embodiment, the impact surface may be the wall surface of the cover body 120 or the base 110 corresponding to the extension arm 152, for example, the impact surface 1181 of the impact portion 118 of the base 110.

5A and 5B are a top view and a cross-sectional view of the key structure 10 of FIG. 1A in the second state. As shown in FIGS. 5A and 5B, when the key structure 10 is in the second state, the adjusting member 160 abuts the positioning portion 151 and is located at the second position in the X-axis direction. At this time, the feel elastic member 150 has a second deformation, so that the pressing force required for the key shaft 130 to move toward the base 110 and to move the moving portion 131 over the extension arm 152 is the second pressing force. For example, the second position of the adjusting member 160 may be closer to the actuating portion 131 than the first position, that is, the adjusting lever 161 moves toward the inside of the base 110 to push the positioning portion 151 inward, so that the preload of the feel-elastic member 150 increases . When the adjusting member 160 is located at the second position, the extending arm 152 preferably moves downward through the moving portion 131, and the extending arm 152 is located at the second position relative to the moving path. Specifically, the second position of the extension arm 152 is closer to the outer side of the base 110 than the first position, that is, to the apex 1313 of the actuating portion 131 in the Y-axis direction. When the adjusting member 160 is in the second position, when the second pressing force is applied to the key shaft 130, the key shaft 130 is moved toward the base 110 and the moving portion 131 is moved, and the extension arm 152 first moves downward and slides along the lower contact surface 1311 After reaching the apex 1313, and after passing the apex 1313, it moves upward to strike the impact surface of the base 110 or the cover 120 to generate a sound (for example, a second sound). In other words, when the feel-elastic member 150 has the second deformation, the extension arm 152 first slides along the lower contact surface 1311 to the apex 1313, and the extension arm 152 reaches the vertex 1313 after sliding the second contact surface 1311 a second distance, and the extension arm 152 later After crossing the apex 1313, it moves away from the bump and moves upward. In this embodiment, since the extension arm 152 is closer to the apex 1313 than the first position in the second position, the first distance is greater than the second distance. It should be noted here that when the extension arm 152 reaches the apex 1313, the extension arm 152 and the impact surface have a second utterance distance, and the extension arm 152 strikes the impact surface to generate a second sound.

Specifically, when the adjusting member 160 is in the first position or the second position, the pre-pressure caused by the deformation of the feel-elastic member 150 is preferably still within the range where the actuating portion 131 can push the extension arm 152 downward. Therefore, when sufficient pressing force (such as the first pressing force or the second pressing force) is applied to the key shaft 130, the extending arm 152 will be pushed downward by the actuating portion 131 to move downward first and slide along the lower contact surface 1311 to The apex 1313, and after passing the apex 1313, is moved upwards by the resilience to hit the impact surface (for example, 1181) of the base 110 or the cover 120 to generate a sound. It should be noted here that in this embodiment, when the adjusting member 160 is in the second position, the position of the extending arm 152 relative to the moving path is different from that when the adjusting member 160 is in the first position, the extending arm 152 is relatively moving The location of the path. That is, when the adjustment member 160 is in the first position, the first sounding distance between the extension arm 152 and the impact surface 1181 is different from that between the extension arm 152 and the impact surface 1181 when the adjustment member 160 is in the second position Second utterance distance. For example, when the adjustment member 160 moves from the first position to the second position, the positioning portion 151 of the handle elastic member 150 is pushed and displaced by the adjustment rod 161, so that the handle elastic member 150 changes from the first deformation to the second position The deformation further increases the pre-pressure of the feel elastic member 150 from the first pre-pressure to the second pre-pressure. Therefore, the extension arm 152 is moved downward by the actuation portion 131 in the first position more than the extension arm 152 is moved downward by the actuation portion 131 in the second position, that is, the first utterance interval is greater than the second utterance interval, The volume of the first sound is greater than the volume of the second sound. In other words, when the preload caused by the deformation of the feel elastic member 150 is large, the displacement of the extending arm 152 relative to the impact surface 1181 is small, so the generated sound is small.

Furthermore, as the adjustment member 160 moves toward the inner side of the base 110 in the X-axis direction, the relative displacement of the positioning portion 151 increases, so that the preload of the torsion spring increases. When the preload of the torsion spring reaches a certain level, the force of the torsion spring is too large, the key shaft 130 cannot press the torsion spring, and the extension arm 152 is pushed out from the side, thereby creating a frustrating feel. 6A and 6B are a top view and a cross-sectional view along the tangent line BB of the key structure 10 of FIG. 1A in the third state. As shown in FIGS. 6A and 6B, when the key structure 10 is in the third state, the adjusting member 160 abuts the positioning portion 151 and is located at a third position in the X-axis direction. At this time, the feel elastic member 150 has a third deformation so that the extending arm 152 is located at a third position relative to the moving path. Specifically, the third position of the adjusting member 160 can be deeper inside the base 110 than the second position, so that the extension arm 152 preferably corresponds substantially to the apex 1313 of the actuating portion 131 when it is in the third position. In other words, the adjustment rod 161 further moves toward the base 110 and pushes the positioning portion 151 further inward, so that the preload of the feel elastic member 150 increases, and the actuating portion 131 cannot push the extension arm 152 downward. Therefore, when the adjusting member 160 is located at the third position and pressing force is applied to the key shaft 130, the key shaft 130 moves toward the base 110 and drives the moving portion 131 to push the extension arm 152 out of the moving path in the Y-axis direction, causing a setback Feel. At this time, since the actuating portion 131 does not press down the extension arm 152, the extension arm 152 is only displaced laterally, and does not press down and hit the impact surface 1181, so no sound is generated.

Furthermore, when the moving distance of the adjusting member 160 in the X-axis direction is large enough to deform the handle elastic member 150 and the position is shifted, and the extension arm 152 is located outside the moving path of the actuating portion 131, the key structure 10 can provide a linear feel. 7A and 7B are a top view and a cross-sectional view along the tangent line BB of the key structure 10 of FIG. 1A in the fourth state. As shown in FIGS. 7A and 7B, when the key structure 10 is in the fourth state, the adjusting member 160 abuts the positioning portion 151 and is located at the fourth position in the X-axis direction. At this time, the feel elastic member 150 has a fourth deformation so that the extending arm 152 is located at a fourth position outside the moving path of the actuating portion 131. For example, the fourth position of the adjustment member 160 may be deeper inside the base 110 than the third position, that is, the adjustment rod 161 moves further toward the base 110 and pushes the positioning portion 151 further inward, so that the elastic member 150 feels The preload increases, and the extension arm 152 is displaced in the Y-axis direction and is separated from the movement path of the actuation portion 131. Specifically, when the adjusting member 160 is located at the fourth position, the extending arm 152 is located at the fourth position outside the moving path of the actuating portion 131, so when pressing force is applied to the key shaft 130, the key shaft 130 moves toward the base 110 and drives The actuating portion 131 moves along the moving path without interfering with the extension arm 152 to produce a linear feel.

It should be noted here that although the embodiments of FIGS. 4A to 7B sequentially show that the adjustment member 160 moves in different positions along the X-axis direction toward the inside of the base 110, the adjustment member 160 may also move differently toward the outside of the base 110 along the X-axis direction. The positioning portion 151 can move along with the adjustment member 160 toward the outside of the base 110 by the elastic restoring force of the deformation, so as to have a deformation corresponding to the position of the adjustment member 160 in the X-axis direction, and thus provide a corresponding pressing feel. Specifically, according to the actual application, the key structure 10 can selectively provide two or more pressing feelings by controlling the position of the adjusting member 160 in the X-axis direction. In other words, the adjustment member 160 can be moved toward the inside or outside of the base 110 in the X-axis direction to selectively control the position of the adjustment member 160 at (1) to make the deformation (or pre-pressure) of the feel elastic member 150 on the key shaft When 130 moves toward the base 110 and moves the moving part 131, the moving part 131 can press down the extension arm 152, thereby displacing the extension arm 152 in the Z-axis direction and striking the position of the impact surface 1181 (such as the first in the X-axis direction) Position, second position, or any suitable position before reaching the third position), and can provide a variety of different feelings of pressing force, and can emit sounds of different volumes; (2) deform the elastic member 150 (or (Preload) When the key shaft 130 moves toward the base 110 and drives the moving part 131, the moving part 131 pushes the position of the extension arm 152 toward the outside of the moving path (for example, the third position in the X-axis direction), thereby providing a silent Frustration; or (3) the deformation (or pre-pressure) of the elastic member 150 makes the extension arm 152 located outside the moving path. When the key shaft 130 moves toward the base 110 and moves the moving part 131, the moving part 131 will not Interference with the extension arm 152 (for example, the fourth position in the X-axis direction) can provide a silent linear feel.

In the above embodiment, the recovery unit and the touch elastic member are separate components, but not limited to this. In another embodiment, the spring as the restoring unit and the touch elastic member can be integrated into a single component that is integrally formed. 8A and 8B are respectively explosion schematic diagrams of a key structure at different viewing angles according to another embodiment of the present invention, and FIG. 8C is a schematic assembly view of the key structure of FIG. 8A without a cover. As shown in FIGS. 8A to 8C, the key structure 20 of the present invention includes a base 210, a cover 120, a key shaft 130, a composite elastic member 240 and an adjusting member 260. In addition, the key structure 20 may further include an electrode module 170, a light source unit 180, a circuit board (for example, 290), a bottom plate, and the like. In this embodiment, the cover 120, the key shaft 130, the electrode module 170, and the light source unit 180 have similar or similar structural details and connection relationships as the embodiment of FIG. 1A. For example, the cover 120 has a button hole portion 121 and an opening 122; the key shaft 130 has an actuating portion 131, an actuating portion 132, a limiting portion 133, and an engaging portion 134; the electrode module 170 includes a first electrode sheet 171 and a Two electrode pieces 172, and the first electrode piece 171 has an elastic portion 1711; the light source unit 180 includes a light source 181 and a light guide column 182. It should be noted here that for the structural details and connection relationships of the cover 120, the key shaft 130, the electrode module 170, and the light source unit 180, reference may be made to the related description in the embodiment of FIG. 1A, and details are not repeated herein. In addition, in this embodiment, the electrode module 170 can also be replaced by other switching components, such as an optical axis switch, which will not be repeated here. Furthermore, similar to the embodiment of FIG. 1A, corresponding to the cover 120, the electrode module 170, and the light source unit 180, the base 210 may have a positioning post 112, a positioning portion 113, an accommodating portion 1131, a first electrode hole 114, and a second For the electrode hole 115, the impact portion 118, the buckle portion 119, etc., and for the structural details, reference may be made to the relevant description of the embodiment of FIG. 1A, and details are not described herein again. The differences between the base 210, the composite elastic member 240, the adjustment member 260, and the circuit board 290 are different from the embodiment of FIG. 1A.

In this embodiment, the composite elastic member 240 includes a spring body 243, a positioning portion 241, and an extension arm 242. The spring body 243 is disposed between the base 210 and the key shaft 130 to provide a restoring force to move the key shaft 130 away from the base 210. The positioning portion 241 is connected to the spring body 243 and the extending arm 242. The positioning portion 241 is positioned at the positioning hole 211 of the base 210, and the extending arm 242 extends corresponding to the actuating portion 131. Furthermore, the adjusting member 260 is preferably disposed corresponding to the feel-elastic member formed by the positioning portion 241 and the extending arm 242. The adjustment member 260 includes an X-axis adjustment member 261 and a Y-axis adjustment member 262. The X-axis adjuster 261 is provided corresponding to the positioning portion 241, and the Y-axis adjuster 262 is provided corresponding to the extension arm 242.

Specifically, the spring body 243 is similar to the recovery unit 140 of the embodiment of FIG. 1A, and may be in the form of a spring. The positioning portion 241 and the extension arm 242 are preferably formed by bending a rod body extending from one end (for example, the lower end) of the spring body 243, and the positioning portion 241 and the extension arm 242 are used as the handle elastic members of the key structure 20. In this embodiment, the positioning portion 241 preferably includes a horizontal portion 2411 and an upright portion 2412. The horizontal portion 2411 is connected between the upright portion 2412 and the spring body 243, and the horizontal portion 2411 preferably extends from one end of the spring body 243 to the positioning hole 211 of the base 210. The upright portion 2412 is substantially bent upward in the Z-axis direction relative to the horizontal portion 2411, and the extension arm 242 is bent and extended in the X-axis direction relative to the upright portion 2412. In this embodiment, the angle between the extension arm 242 and the upright portion 2412 is preferably not greater than 120 degrees.

Corresponding to the composite elastic member 240 and the adjusting member 260, the base 210 has a positioning hole 211, a channel portion 212, an opening portion 216, and a limiting portion 217. In this embodiment, the positioning hole 211 is a through hole opened at the bottom of the base 210, and the opening 216 is preferably a notch partially hollowed from the side wall adjacent to the positioning hole 211 toward the bottom of the base 210, and the opening 216 communicates with the positioning hole 211, to allow the positioning portion 241 to move in the positioning hole 211 in response to the movement of the adjustment member 260. The limiting portion 217 preferably corresponds to the upper section of the positioning portion 241 (that is, the portion of the upright portion 2412 adjacent to the extending arm 242) to limit the displacement of the positioning portion 241. Specifically, when the spring body 243 is sleeved on the positioning portion 113 of the base 210, the horizontal portion 2411 of the positioning portion 241 extends to the positioning hole 211, and the lower portion of the upright portion 2412 is exposed in the opening portion 216 to correspond to the X-axis adjustment member 261, And the upper part of the upright portion 2412 is positioned by the limiting portion 217, and the extending arm 242 extends below the actuating portion 131 in the X-axis direction and spans above the channel portion 212. For example, the limiting portion 217 can be a groove formed on the wall surface of the base 210, or a wall surface where the connection between the upright portion 2412 and the extension arm 242 can bear. The channel portion 212 may be a through hole opened in the Y-axis direction to allow the Y-axis adjusting member 262 to move in the channel portion 212 to change the position of the extension arm 242 relative to the moving path of the actuating portion 131.

In one embodiment, the X-axis adjusting member 261 includes an X-axis adjusting lever 2611 and an X-axis connecting portion 2612. The X-axis connecting portion 2612 is provided below the circuit board 290, and the X-axis adjusting lever 2611 is connected to the X-axis connecting portion 2612 and protrudes in the direction of the cover 120 (for example, the Z-axis direction). For example, the circuit board 290 has an X-axis moving groove 294 corresponding to the opening 216, and the X-axis adjusting lever 2611 is inserted upward from the bottom of the circuit board 290 into the X-axis moving groove 294, and then extends into the opening 216 to correspond to the exposed hole The positioning portion 241 in 211 (that is, the lower section of the upright portion 2412). When the X-axis adjusting member 261 moves, the X-axis adjusting lever 2611 can drive the positioning portion 241 to change the deformation of the positioning portion 241 and the extension arm 242 relative to the spring body 243, thereby changing the key shaft 130 toward the base 210 and driving The pressing force required for the movement portion 131 to move relative to the extension arm 242.

In addition, the Y-axis adjuster 262 includes a Y-axis adjuster 2621 and a Y-axis connecting portion 2622. The Y-axis connecting portion 2622 is provided below the circuit board 290, and the Y-axis adjusting lever 2621 is connected to the Y-axis connecting portion 2622 and protrudes in the direction of the cover 120 (for example, the Z-axis direction). For example, the circuit board 290 has a Y-axis moving groove 295 corresponding to the channel portion 212, and the Y-axis adjusting lever 2621 is inserted into the Y-axis moving groove 295 upward from below the circuit board 290 to protrude the channel portion 212 upward to correspond to the extending arm 242. When the Y-axis adjusting member 262 moves, the Y-axis adjusting lever 2621 can drive the extension arm 242 to move in the Y-axis direction, thereby changing the position of the extension arm 242 relative to the moving path of the actuating portion 131.

In this embodiment, the Y-axis adjustment lever 2621 preferably has a notch portion 2623, and the notch portion 2623 is preferably recessed inwardly from the wall surface facing the extension arm 242 to correspond to the long axis direction of the extension arm 242. For example, the notch portion 2623 may be an L-shaped notch, that is, the Y-axis adjustment rod 2621 has a stepped top surface for the extension arm 242 to straddle the notch portion 2623 of the Y-axis adjustment rod 2621, thereby strengthening the Y The coordinated positioning of the shaft adjusting lever 2621 and the extension arm 242 is not limited thereto. In other embodiments, the Y-axis adjustment lever 2621 may not have the notch portion 2623, and the wall surface of the Y-axis adjustment lever 2621 abuts the extension arm 242. In addition, although not shown, in another embodiment, the X-axis adjusting lever 2611 may optionally have a limiting groove 1611 similar to the adjusting lever 161 of the embodiment of FIG. 1A to accommodate the upright portion 2412 of the positioning portion 241 The next paragraph will not be repeated here.

Next, referring to FIGS. 10A to 10C, the operation of the key structure 20 of the present invention using the X-axis adjustment member 261 to adjust the feel of pressing is illustrated. FIG. 10A is a schematic view of the key structure of FIG. 8A without a cover, FIGS. 10B and 10C. These are schematic cross-sectional views along the tangent line CC of FIG. 10A when the X-axis adjusting member is at different positions. As shown in FIG. 10B, when the X-axis adjustment member 261 is located at the first position in the X-axis direction, the X-axis adjustment lever 2611 abuts the lower end of the upright portion 2412 of the positioning portion 241, and the positioning portion 241 and the extension arm 242 are relative to the spring body 243 has a first deformation, that is, there is a first pre-pressure between the positioning portion 241 and the extension arm 242, which further moves the key shaft 130 toward the base 210 and drives the moving portion 131 to move relative to the extension arm 242. One-touch pressure. Specifically, when the X-axis adjustment member 261 is located at the first position, the extension arm 242 preferably moves downward through the actuating portion 131 (that is, the movement path is parallel to the Z-axis direction). When the X-axis adjusting member 261 is in the first position, when the first pressing force is applied to the key shaft 130, the key shaft 130 is moved toward the base 210 and the moving part 131 is moved, and the extension arm 242 first moves downward and moves downward along the contact surface 1311 slides to the apex 1313, and after crossing the apex 1313, moves upward to strike the base 210 or the cover 120 to generate a sound (for example, a first sound). In other words, when there is a first deformation between the positioning portion 241 and the extending arm 242 (that is, the feel elastic member has the first X-axis deformation), the extending arm 242 first slides along the lower contact surface 1311 to the apex 1313, and the extending arm 242 is below The sliding surface 1313 slides the first distance and reaches the apex 1313. After the extension arm 242 passes the apex 1313 later, it moves away from the bump and moves upward. It should be noted here that when the extension arm 242 reaches the apex 1313, the impact surface of the extension arm 242 and the base 210 or the cover body 120 has a first utterance distance, and the extension arm 242 strikes the impact surface to generate a first sound. In this embodiment, the impact surface may be the wall surface of the cover body 120 or the base 210 corresponding to the extension arm 242, for example, the impact surface 1181 of the impact portion 118 of the base 210.

As shown in FIG. 10C, when the X-axis adjustment member 261 moves in the X-axis direction, for example, toward the inside of the base 210, the X-axis adjustment lever 2611 pushes the lower end of the positioning portion 241 in the positioning hole 211 along X The displacement in the axial direction changes the positions of the positioning portion 241 and the extension arm 242 relative to the spring body 243 (that is, produces different deformations), that is, the preload changes. Specifically, when the X-axis adjuster 261 is located at the second position in the X-axis direction, the X-axis adjuster 2611 abuts the lower end of the upright portion 2412 of the positioning portion 241, and the positioning portion 241 and the extension arm 242 have relative to the spring body 243 The second deformation, that is, there is a second pre-pressure between the positioning portion 241 and the extension arm 242, and then the key shaft 130 is moved toward the base 210 and the pressing force required to move the moving portion 131 relative to the extension arm 242 is the second pressure pressure. Specifically, when the X-axis adjuster 261 is located at the second position in the X-axis direction, the extension arm 242 preferably moves downward through the actuating portion 131 (that is, the movement path is parallel to the Z-axis direction). When the X-axis adjusting member 261 is located at the second position in the X-axis direction, and the second pressing force is applied to the key shaft 130, the key shaft 130 is moved toward the base 210 and the moving part 131 is moved, and the extension arm 242 first moves downward And slide along the lower contact surface 1311 to the apex 1313, and after passing the apex 1313, move upward to strike the base 210 or the cover 120 to generate a sound (for example, a second sound). In other words, when there is a second deformation between the positioning portion 241 and the extension arm 242 (that is, the feel elastic member has a second X-axis deformation), the extension arm 242 first slides along the lower contact surface 1311 to the apex 1313, and the extension arm 242 is below The sliding surface 1311 slides a second distance to reach the apex 1313, and the extension arm 242 later passes the apex 1313, and then moves away from the bump and moves upward. In this embodiment, since the extension arm 242 is closer to the apex 1313 than the first position in the second position, the first distance is greater than the second distance. It should be noted here that when the extension arm 242 reaches the apex 1313, the impact surface (for example, 1181) of the extension arm 242 and the base 210 or the cover 120 has a second utterance distance, and the extension arm 242 strikes the impact surface to generate a second sound.

In this embodiment, when the X-axis adjustment member 261 moves from the first position to the second position in the X-axis direction, the positioning portion 241 is pushed and displaced by the X-axis adjustment lever 2611, and the first deformation is transformed into the second deformation And the first pre-pressure increases to the second pre-pressure. Therefore, the distance that the extension arm 242 is moved downward by the actuating portion 131 in the first position is greater than the distance that the extension arm 242 is moved downward by the actuating portion 131 in the second position, that is, the first utterance interval is greater than the second utterance interval, The volume of the first sound is greater than the volume of the second sound. In other words, when the preload due to deformation between the positioning portion 241 and the extension arm 242 is large, the displacement of the extension arm 242 relative to the impact surface 1181 is small, so the generated sound is small.

Hereinafter, referring to the drawings, the operation of the key structure 20 of the present invention to adjust the feel of pressing using the Y-axis adjusting member 262 will be described. 11A and 11B are a top view and a cross-sectional view along the tangent line DD when the Y-axis adjusting member 262 of the key structure 20 of FIG. 8A is in the first position. As shown in FIGS. 11A and 11B, when the Y-axis adjusting member 262 is in the first position in the Y-axis direction, the positioning portion 241 and the extension arm 242 have a first deformation relative to the spring body 243, and the extension arm 242 is relative to the actuating portion The movement path of 131 is located at the first position in the Y-axis direction. For example, when the Y-axis adjusting member 262 is at the first position in the Y-axis direction, the extension arm 242 preferably moves downward through the actuating portion 131 (that is, the movement path is parallel to the Z-axis direction), and the key shaft The pressing force required for 130 to move toward the base 210 and drive the moving part 131 to cross the extension arm 242 is the first pressing force. When the Y-axis adjusting member 262 is located at the first position and the first pressing force is applied to the key shaft 130, the key shaft 130 is moved toward the base 210 and the moving part 131 is moved, and the extension arm 242 first moves downward and moves downward along the contact surface 1311 slides to the apex 1313, and after crossing the apex 1313, moves upward to strike the base 210 or the cover 120 to generate a sound (for example, a first sound). In other words, when there is a first deformation between the positioning portion 241 and the extension arm 242 (that is, the feel elastic member has a first Y-axis deformation), the extension arm 242 first slides along the lower contact surface 1311 to the apex 1313, and the extension arm 1311 is below The sliding surface 1311 slides the first distance and reaches the apex 1313. After the extension arm 242 passes the apex 1313 later, it moves away from the bump and moves upward. It should be noted here that when the extension arm 242 reaches the apex 1313, the impact surface of the extension arm 242 and the base 210 or the cover 120 (for example, the impact surface 1181 of the impact portion 118 of the base 210) has the first utterance distance, and the extension arm 242 knocks Hit the impact surface to produce the first sound.

12A and 12B are a top view and a cross-sectional view along the tangent line DD when the Y-axis adjustment member 262 of the key structure 20 of FIG. 8A is in the second position. As shown in FIGS. 12A and 12B, when the Y-axis adjuster 262 is in the second position in the Y-axis direction, the positioning portion 241 and the extension arm 242 have a second deformation relative to the spring body 243, and the extension arm 242 is opposite to the actuating portion The movement path of 131 is located at the second position in the Y-axis direction. For example, when the Y-axis adjusting member 262 is at the second position in the Y-axis direction, the extension arm 242 preferably moves downward through the actuating portion 131 (that is, the movement path is parallel to the Z-axis direction), and the key shaft The pressing force required for 130 to move toward the base 210 and drive the moving part 131 over the extension arm 152 is the second pressing force. In this embodiment, when the Y-axis adjusting member 262 is located at the second position in the Y-axis direction, the second position of the Y-axis adjusting member 262 in the Y-axis direction may be closer to the outside of the base 210 than the first position, for example, closer to the actuator The apex 1313 of 131. In other words, the Y-axis adjustment lever 2621 moves toward the outside of the base 210 in the Y-axis direction and pushes the extension arm 242 outward, so that the preload between the extension arm 242 and the positioning portion 241 increases. When the Y-axis adjusting member 262 is located at the second position, and the second pressing force is applied to the key shaft 130, the key shaft 130 is moved toward the base 210 and the moving part 131 is moved, and the extension arm 242 first moves downward and moves downward along the contact surface 1311 slides to the apex 1313, and after passing the apex 1313, moves upward to strike the impact surface of the base 210 or the cover 120 to generate a sound (for example, a second sound). In other words, when there is a second deformation between the positioning portion 241 and the extension arm 242 (that is, the feel elastic member has a second Y-axis deformation), the extension arm 242 first slides along the lower contact surface 1311 to the apex 1313, and the extension arm 242 is below The sliding surface 1311 slides a second distance to reach the apex 1313, and the extension arm 242 later passes the apex 1313, and then moves away from the bump and moves upward. In this embodiment, since the extension arm 242 is closer to the apex 1313 than the first position in the second position, the first distance is greater than the second distance. It should be noted here that when the extension arm 242 reaches the apex 1313, the extension arm 242 and the impact surface (for example, the impact surface 1181 of the impact portion 118 of the base 210) have a second utterance distance, and the extension arm 242 strikes the impact surface to generate a second sound.

Specifically, when the Y-axis adjusting member 262 is located at the first position or the second position in the Y-axis direction, the preload caused by the deformation of the positioning portion 241 and the extension arm 242 is still in the actuating portion 131 and can move the extension arm 242 downward Within range. Therefore, when sufficient pressing force (such as the first pressing force or the second pressing force) is applied to the key shaft 130, the extending arm 242 will be downwardly pushed by the actuating portion 131 to move downward first and slide along the lower contact surface 1311 to The apex 1313, and after passing the apex 1313, is moved upwards by the resilience to hit the impact surface (eg, 1181) of the base 210 or the cover 120 to generate a sound. It should be noted here that in this embodiment, when the Y-axis adjustment member 262 moves from the first position to the second position in the Y-axis direction, the extension arm 242 is pressed and displaced by the Y-axis adjustment lever 221 and changes relative to the actuating portion The position of the movement path of 131 causes the first deformation to change into the second deformation, and the first pre-pressure increases to the second pre-pressure. Therefore, the distance that the extension arm 242 is moved downward by the actuating portion 131 in the first position is greater than the distance that the extension arm 242 is moved downward by the actuating portion 131 in the second position, that is, the first utterance interval is greater than the second utterance interval, The volume of the first sound is greater than the volume of the second sound. In other words, when the preload due to deformation between the positioning portion 241 and the extension arm 242 is large, the displacement of the extension arm 242 relative to the impact surface 1181 is small, so the generated sound is small.

Furthermore, as the Y-axis adjuster 262 moves toward the outside of the base 210 in the Y-axis direction, the greater the displacement of the extension arm 242 with respect to the moving path of the actuating portion 131. For example, when the extension arm 242 is substantially at a position corresponding to the apex 1313 of the actuating portion 131 with respect to the moving path, the preload caused by the deformation between the positioning portion 241 and the extension arm 242 is too large, and the key shaft 130 cannot press the torsion spring, thereby extending the extension arm 242 is pushed out from the side, and a feeling of frustration is produced. 13A and 13B are a top view of the Y-axis adjusting member 262 of the key structure 20 of FIG. 8A at a third position and a cross-sectional view along the tangent line DD. As shown in FIGS. 13A and 13B, when the Y-axis adjustment member 262 is in the third position in the Y-axis direction, the positioning portion 241 and the extension arm 242 have a third deformation relative to the spring body 243 (that is, the feel elastic member has a third Y (The axial direction is deformed), and the extension arm 242 is located at the third position in the Y-axis direction relative to the movement path of the actuating portion 131. Specifically, the third position of the Y-axis adjuster 262 in the Y-axis direction can be closer to the outside of the base 210 than the second position, that is, substantially corresponds to the apex 1313 of the actuating portion 131. In other words, the Y-axis adjustment lever 2621 further moves toward the outside of the base 210 in the Y-axis direction and pushes the extension arm 242 further outward, so that the preload between the extension arm 242 and the positioning portion 241 increases, and the extension arm 242 in the Z-axis direction The position substantially corresponds to the apex 1313 of the actuator 131. Therefore, when the Y-axis adjusting member 262 is located at the third position and the pressing force is applied to the key shaft 130, the key shaft 130 moves toward the base 210 and drives the moving portion 131 to push the extension arm 242 out of the moving path in the Y-axis direction, resulting in Frustrated feel. At this time, since the actuating portion 131 does not press down the extension arm 242, the extension arm 242 is only laterally displaced, and does not press down and hit the impact surface 1181, so no sound is generated.

Furthermore, when the movement distance of the Y-axis adjusting member 262 in the Y-axis direction is so large that the extension arm 242 is deviated out of the moving path of the actuating portion 131, the key structure 20 can provide a linear feel. 14A and 14B are a top view and a cross-sectional view along the tangent line DD when the Y-axis adjusting member 262 of the key structure 20 of FIG. 8A is in the fourth position. As shown in FIGS. 14A and 14B, when the Y-axis adjusting member 262 is in the fourth position in the Y-axis direction, the positioning portion 241 and the extending arm 242 have a fourth deformation relative to the spring body 243 (that is, the feel elastic member has the fourth Y (The axial direction is deformed), and the extending arm 242 is located at a fourth position in the Y-axis direction relative to the moving path of the actuating portion 131, that is, a position outside the moving path. For example, the fourth position of the Y-axis adjusting member 262 in the Y-axis direction may be closer to the outside of the base 210 than the third position, that is, the Y-axis adjusting lever 2621 moves further toward the outside of the base 210 along the Y-axis direction and further outward The extension arm 242 is pushed so that the preload between the extension arm 242 and the positioning portion 241 increases, and the extension arm 242 is displaced toward the outside of the base 210 in the Y-axis direction to be separated from the moving path of the actuating portion 131. Therefore, when the Y-axis adjustment member 262 is located at the fourth position and pressing force is applied to the key shaft 130, the key shaft 130 moves toward the base 210 and drives the moving portion 131 downward without interfering with the extension arm 242 to produce a linear feel .

It should be noted here that although the embodiments of FIGS. 10B and 10C sequentially show that the X-axis adjustment member 261 moves to different positions along the X-axis direction toward the inside of the base 210, the X-axis adjustment member 261 may also move toward the base 210 along the X-axis direction The outer side moves to different positions, and the positioning portion 241 can move toward the outer side of the base 210 with the X-axis adjustment member 261 by the elastic recovery force of the deformation, and has a deformation corresponding to the position of the X-axis adjustment member 261 in the X-axis direction, thereby providing corresponding The feeling of pressing. In addition, although the embodiments of FIGS. 11A to 14B sequentially show that the Y-axis adjusting member 262 moves in different positions along the Y-axis direction toward the outside of the base 210, the Y-axis adjusting member 262 can also move toward the inside of the base 210 along the Y-axis direction. At different positions, the extension arm 242 can move along with the Y-axis adjustment member 262 toward the inside of the base 210 by the elastic recovery force of the deformation, and has a deformation corresponding to the position of the Y-axis adjustment member 262 in the Y-axis direction to be located at the corresponding The position of the moving path of the actuating portion 131 provides a corresponding pressing feel. Specifically, according to the actual application, the key structure 20 can selectively provide two or more pressing feelings by controlling the position of the X-axis adjusting member 261 in the X-axis direction or the position of the Y-axis adjusting member 262 in the Y-axis direction. In other words, the X-axis adjusting member 261 can move toward the inside or outside of the base 210 in the X-axis direction to selectively control the position of the X-axis adjusting member 261, (1) deform the positioning portion 241 and the extension arm 242 (Or preload) When the key shaft 130 moves toward the base 210 and moves the moving part 131, the moving part 131 can press down the extension arm 242, so that the extension arm 242 is displaced in the Z-axis direction and strikes the position of the impact surface 1181 ( For example, the first position or the second position in the X-axis direction), and can provide a variety of different pressing feeling, but also can emit sounds of different volume. Furthermore, the Y-axis adjusting member 262 can be moved toward the outside or inside of the base 210 in the Y-axis direction to selectively control the position of the Y-axis adjusting member 262 at (1) the extension arm 242 moves through the actuating portion 131 Path, and the deformation (or preload) between the positioning portion 241 and the extension arm 242 when the key shaft 130 moves toward the base 210 and drives the moving portion 131, the actuating portion 131 can press down the extension arm 242, causing the extension arm 242 to generate The displacement in the Z-axis direction strikes the position of the impact surface 1181 (such as the first position in the Y-axis direction, the second position, or any suitable position before reaching the third position), (2) makes the extension arm 242 substantially correspond The apex 1313 of the actuating portion 131, and the deformation (or preload) between the positioning portion 241 and the extension arm 242 when the key shaft 130 moves toward the base 210 and drives the actuation portion 131 to move, the actuation portion 131 pushes the extension arm outward from the movement path The position of 242 (such as the third position in the Y-axis direction), which can provide a silent feeling of frustration; or (3) The extension arm 242 is located outside the moving path, and the key shaft 130 moves toward the base 210 and drives the moving part When 131 moves, the actuating portion 131 does not interfere with the extension arm 242 (for example, the fourth position in the X-axis direction), and can provide a silent linear feel.

It should be noted here that the button structure 20 of the present invention can be adjusted by the X-axis adjustment member 261 or the Y-axis adjustment member 262 to achieve the desired pressing feel, or by the X-axis adjustment member 261 and the Y-axis adjustment member The adjustment of 262 can achieve the desired pressing feel. In other words, in other embodiments, the key structure 20 of the present invention may only include the X-axis adjustment member 261 or the Y-axis adjustment member 262, and is not limited to the X-axis adjustment member 261 and the Y-axis adjustment member 262 as shown in the embodiment. Furthermore, when adjusted by the X-axis adjustment member 261, the first position or the second position of the extension arm 242 may be the same as or different from the first position of the extension arm 242 when adjusted by the Y-axis adjustment member 262 One position or second position. Therefore, when the X-axis adjustment member 261 moves to the first position or the second position, the key shaft 130 moves toward the base 210 and drives the moving portion 131 to cross the extension arm 242. The pressing force required may be the same or different by Y When the shaft adjusting member 262 moves to the first position or the second position, the key shaft 130 moves toward the base 210 and drives the moving portion 131 to pass the pressing force required by the extending arm 242.

Furthermore, in the present invention, the design of the positioning part can be changed to enhance the positioning of the touch elastic member and the base. In one embodiment, as shown in FIGS. 15A to 15C, the feel elastic member 410 is implemented as a torsion spring, and includes a positioning portion 412, an extension arm 414, and a torsion spring body 416, wherein the positioning portion 412 and the extension arm 414 are self-torsion springs The main body 416 extends from opposite ends, and the extending direction of the positioning portion 412 and the extending direction of the extending arm 414 have an included angle. The included angle is preferably not greater than 120 degrees. It should be noted here that the handle elastic member 410 and the base 510 are similar to the handle elastic member 150 and the base 110 in the embodiment of FIG. 1A, and the related structural details and the positional relationship or connection relationship with other key structure elements can refer to FIG. 1A Relevant instructions will not be repeated here. In the following, only the positioning of the base 510 and the elastic handle 410 will be described.

In this embodiment, the handle elastic member 410 is positioned on the base 510 by the positioning portion 412, and the positioning portion 412 has a curved section 413. The curved section 413 preferably abuts the base 510 to limit the displacement of the positioning portion 412, thereby increasing assembly efficiency and reset accuracy during operation. Specifically, the base 510 has a coupling surface 518, and the curved section 413 preferably abuts the coupling surface 518. Specifically, the base 510 preferably has a positioning hole 511, a locking portion 512, and an opening 516, wherein the opening 516 communicates with the positioning hole 511, and the coupling surface 518 is a wall surface on the opening 516. The bonding surface 518 is preferably parallel to the bending path of the curved section 413, so that the curved section 413 has a curved line segment acting surface when abutting the bonding surface 518, that is, the vertical projection range of the curved section 413 on the bonding surface 518 preferably covers the surface area. One of the two-dimensional extension directions of the bonding surface 518 is preferably parallel to the extension direction of the extension arm 414, for example, the X-axis direction. For example, the bonding surface 518 of the base 510 preferably extends along the XZ axis plane, and the curved section 413 preferably extends along the XZ axis plane, so that the curved line segment acting surface is the curved section 413 projected vertically on the surface surrounded by the bonding surface 518 Zone, where the XZ axis plane is parallel to the X axis and the Z axis, and the X axis, Z axis, and Y axis are perpendicular to each other. The locking portion 512 is disposed in the opening portion 516 and corresponds to the positioning hole 511 for engaging the curved section 413. That is, the curved section 413 extends into the positioning hole 511 of the base 510 and interferes with the buckling portion 512 of the base 510, so that the positioning portion 412 can be restricted from coming out of the positioning hole 511. For example, the locking portion 512 is preferably a protruding column that protrudes from the base 510 defining the side wall of the opening 516 (that is, the coupling surface 518) toward the opening 516, and the portion of the locking portion 512 connected to the coupling surface 518 preferably has A groove 513 partially recessed in the radial direction to accommodate a portion of the positioning portion 412. That is, the buckle portion 512 preferably has a cross section with a wide head and a narrow neck, and the head is farther from the neck than the base coupling surface 518, so that the portion of the neck retracted relative to the head is the groove 513. In an embodiment, the base 510 preferably further has a stopper 514, and the stopper 514 is disposed corresponding to the positioning portion 412, so that the positioning portion 412 partially abuts the stopper 514. For example, the blocking block 514 is disposed adjacent to the positioning hole 511, and is preferably disposed on the coupling surface 518 to be located at the side of the locking portion 512, so that the positioning portion 412 is positioned at the positioning hole 511 and leans against the blocking block 514 to restrict the positioning portion 412 displacement.

In this embodiment, the curved section 413 is preferably ring-shaped, so that the curved section 413 can be sleeved on the buckle portion 512 to strengthen the positioning of the base 510 and the handle elastic member 410. For example, the positioning portion 412 is a rod body extending downward from one end of the torsion spring body 416 and bent to form an annular curved section 413, and the curved section 413 preferably has an open ring structure to increase the number of curved sections 413 The elasticity of the buckling portion 512, that is, the end of the curved section 413 is preferably a free end. For example, the annular diameter of the bending section 413 is preferably substantially equal to or smaller than the diameter of the buckling portion 512. When the bending section 413 is sleeved on the buckling portion 512, the bending section 413 can be elastically deformed to be partially accommodated in the groove 513 is in contact with the coupling surface 518, so that the positioning portion 412 is engaged with the locking portion 513 of the base 510. In this way, the positioning of the elastic member 410 and the base 510 can be strengthened, and during the assembly process, the detachment of the elastic member 410 from the base 510 can be prevented, and the assembly efficiency can be improved. Furthermore, during the operation, when the Y-axis adjusting member (for example, 262) protrudes upward from the channel portion 517 of the base 510 to adjust the relative position of the moving path of the extending arm 414 and the actuating portion 131 in the Y-axis direction, The bending section 413 of the positioning section 412 and the buckling section 512 can be positioned and abut the joint surface 518, so that the curved line segment acting surface formed between the bending section 413 and the joint surface 518 prevents the positioning section 412 from rotating around the Z axis And the positioning portion 412 partially (for example, a straight section connected to the curved section 413) leans against the blocking block 514 to effectively control the displacement of the extending arm 414 to increase the accuracy of the feel elastic member 410 returning to the preset position, and it is easier to maintain the feel .

In other embodiments, the curved section of the positioning portion may have different forms to enhance the positioning of the elastic handle 410 and the base 510. As shown in FIGS. 16A and 16B, in another embodiment, the curved section 413' is U-shaped, wherein one end (eg, 4132) of the curved section 413' leans against the blocking block 514, and the other end of the curved section 413' is the free end (For example, 4131), the free end 4131 abuts the bottom surface 515 of the base 510 adjacent to the positioning hole 511. In this embodiment, the bottom surface 515 may be the top surface of the opening 516. Specifically, the positioning portion 412 is a rod body that extends downward from one end of the torsion spring body 416 and is bent along the extending direction of the extending arm 414 (for example, the X-axis direction) to form a U-shaped curved section 413 ′, and the U-shaped opening is Towards the Z-axis direction (for example, upward). That is, one end 4132 of the U-shaped curved section 413' is connected to the torsion spring body 416, and the end of the U-shaped curved section 413' is a free end 4131, so that the positioning portion 412 extends into the positioning hole 511 of the base 510 into the opening portion 516 The end 4132 of the U-shaped curved section 413' connected to the torsion spring body 416 abuts against the stopper 514 of the base 510, and the free end 5131 of the U-shaped curved section 413' is bent upward to abut the bottom surface 515 of the adjacent positioning hole 511. As a result, the positioning portion 412 and the base 510 can be parallel to the bonding surface 518 by the bending path of the U-shaped bending section 413' and abut against each other to have a surface limit (relative to the linear positioning portion 151 of FIG. 1A) for assembly During the operation, it is possible to prevent the touch elastic member 410 from detaching from the base 510 and increase the accuracy of the touch elastic member 410 returning to the preset position.

In yet another embodiment, as shown in FIGS. 17A and 17B, the curved section 413" is U-shaped, and the U-shaped opening faces laterally (for example, toward the X-axis direction or the Y-axis direction). In this embodiment, the curved section 413 The U-shaped opening of "" is preferably oriented in the X-axis direction. Specifically, relative to the embodiment of FIG. 16A, one end of the bending section 413 ″ of this embodiment is connected to the torsion spring body 416, and the other end of the bending section 413 ″ is a free end and extends away from the positioning hole 511. In this embodiment, the bending section 413" has a bending width D, and the bending width D is preferably larger than the width of the positioning hole 511 in the U-shaped opening direction (eg, X-axis direction).
