As shown in fig. 1 to 7, the mouse 100 includes a mouse body 1, a button 2 and a preload adjustment structure 3. One end of the key 2 is pivoted to a position adjacent to the pre-force adjusting structure 3.

The mouse body 1 has a hinge region 11 and a pressing region 12 adjacent to each other, and the mouse body 1 further has two hinge structures 13 (only one is labeled in the figure) and a pressing column opening 14. The two pivoting structures 13 are disposed in the pivoting region 11 at intervals, and the two pivoting structures 13 are both open-loop structures in this embodiment. The pressing column opening 14 is opened in the pressing area 12. In other embodiments, the pivot region 11 and the pressing region 12 are not necessarily adjacent to each other, and may be offset or spaced from each other.

The key 2 includes a pivoting portion 21 and a pressing piece 22. The pivoting portion 21 has two pivots 211 (only one is labeled in the figure), and the pivoting portion 21 is provided with an avoiding groove 212; the two pivots 211 are respectively pivoted to the two pivoting structures 13, and the avoiding groove 212 is located between the two pivots 211. The pivoting portion 21 of the key 2 and the two pivoting structures 13 are mutually matched to be relatively pivoted, and are not limited to the holes of the shaft (that is, one of the pivoting portion 21 and the pivoting structure 13 may be provided with a pivoting structure, and the other may be provided with a pivoting structure), nor limited to the hole-matching structure of this embodiment.

The pressing piece 22 integrally extends from the pivot portion 21, and the pressing piece 22 includes three

abutting structures

221, 222, 223 and a micro switch prop 224, the

abutting structures

221, 222, 223 are disposed adjacent to the pivot portion 21, the micro switch prop 224 extends toward the mouse body 1 and passes through the pressing pole opening 14 from one end of the

abutting structures

221, 222, 223 away from the pivot portion 21 integrally, and the micro switch prop 224 is used for pressing the micro switch 200 disposed in the mouse body 1.

The pivoting portion 21 is pivoted to the two pivoting structures 13 at a pivoting position (not shown), and the micro switch abutting column 224 extends from a pressing center position (not shown) of the pressing sheet 22 toward the mouse body 1, and an initial height h is formed between the pressing center position and the micro switch 200. The initial height h is a height at which the key 2 is not pressed, and is based on a distance from the pressing piece 22 to the microswitch 200 or from the pressing piece 22 to the upper surface of the mouse body 1.

The preload adjusting mechanism 3 includes a base 31 and a stem 32. The base 31 includes a base body 311 and a fixing frame 312. The base body 311 is integrally connected to the mouse body 1, and the base body 311 is provided with six card holes 3111 (only one is labeled in the figure) and a limit groove 3112.

The fixing frame 312 has six elastic hooks 3121 (only one is labeled) and three through bump holes 3122 (only one is labeled). The six elastic hooks 3121 are respectively connected to the six fastening holes 3111 in a snap manner, so that the fixing frame 312 can be detachably fixed to the base body 311. In addition, since the two pivots 211 are located at two sides of the base 31, in order to make the key 2 rotate relative to the mouse body 1 without contacting the base 31, the key 2 is provided with an escape groove 212 at the pivoting portion 21 to prevent the key 2 from hitting the base 31 during rotation.

The stem 32 includes a stem body 321, three

protrusions

322, 323, 324, and a retainer ring 325. The handle body 321 includes an operation portion 3211 and a rotating shaft portion 3212. The operating portion 3211 is for a user to manually operate, the rotating shaft portion 3212 is formed by extending from the operating portion 3211 along the axial direction D1, and the rotating handle 32 is rotatably disposed between the base body 311 and the fixing frame 312; the rotating shaft 3212 further has an axis X parallel to the axial direction D1.

The

protrusions

322, 323, 324 protrude from the stem body 321 along three radial extension lines d1, d2, d3 perpendicular to the axis X and pass through the corresponding protrusion through hole 3122, respectively, for abutting against one of the abutting

structures

221, 222, 223; the radially extending lines d1, d2, d3 form three different azimuth angles a1, a2, a3 with a reference line BL perpendicular to the axis X, respectively. In short, the

protrusions

322, 323, 324 protrude in the radial direction of the stem body 321, and the

protrusions

322, 323, 324 are arranged at intervals in the axial direction of the stem body 321 and are offset from each other. In other embodiments, the bump through hole 3122 may also be a whole body, and the

bumps

322, 323, and 324 all protrude through the bump through hole, which is not limited by the invention.

More specifically, the protrusion 322 protrudes from the surface of the stem body 321 along the radial extension line d1, the protrusion 323 protrudes from the surface of the stem body 321 along the radial extension line d2, and the protrusion 324 protrudes from the surface of the stem body 321 along the radial extension line d3, and the radial extension line d1 forms an azimuth angle a1 with the reference line BL, the radial extension line d2 forms an azimuth angle a2 with the reference line BL, and the radial extension line d3 forms an azimuth angle a3 with the reference line BL; in the present embodiment, the azimuth angles a1, a2, and a3 are 40 °, 90 °, and 140 °, respectively, that is, the difference between the center line (corresponding to the radially extending line d 1) of the bump 322 and the center line (corresponding to the radially extending line d 2) of the bump 323 is 50 °, the difference between the center line (corresponding to the radially extending line d 3) of the bump 324 and the center line of the bump 323 is 50 °, and the difference between the center line of the bump 324 and the center line of the bump 322 is 100 °.

In addition, the

protrusions

322, 323, 324 are located between the pressing center position and the pivot position of the pressing sheet 22, so that when one of the

protrusions

322, 323, 324 and one of the abutting

structures

221, 222, 223 abut against each other, the abutting parts serve as the fulcrum of the key 2, thereby changing the distance between the pressing center position of the pressing sheet 22 and the micro switch 200. The

bumps

322, 323, and 324 are arranged between the pressing center and the pivot position of the pressing sheet 22, or the projection positions of the

bumps

322, 323, and 324 on the connecting line between the pressing center and the pivot position are different. In other embodiments, the radial height of the

tabs

322, 323, 324 relative to the stem body 321 is different. In other embodiments, the arrangement position (or the projection position on the line between the pressing center position and the pivot position) and the radial height of the

protrusions

322, 323, 324 are different. The retainer ring 325 protrudes from the handle body 321 and is rotatably disposed in the retaining groove 3112, so that the handle 32 is rotatably disposed on the base 31.

As described above, in the present embodiment, since there is an angle difference between the center lines of any two

adjacent bumps

322, 323, and 324, when the user rotates the operating portion 3211 to drive the rotating handle 32 to rotate clockwise from the state of fig. 6B by 50 ° to the state of fig. 7, the rotating handle 32 originally contacting the abutting structure 222 through the bump 323 is switched to contact the abutting structure 221 through the bump 322, at this time, since the contact position of the bump 322 and the abutting structure 221 is closer to the pivot position of the key 2 than the contact position of the bump 323 and the abutting structure 222, the fulcrum corresponding to the key 2 is closer to the rotation axis of the key 2, so that the initial height h between the pressing center position of the pressing piece 22 and the micro switch 200 is relatively increased, and further the pre-pressing force applied to the key 2 is increased, that is, the pressing hand feeling of the key 2 is heavier, and the user needs to apply a larger pressing force to make the micro switch abutting column 224 press the micro switch 200.

On the contrary, when the user rotates the rotating handle 32 of fig. 6B counterclockwise by 50 °, the rotating handle 32 originally contacting the abutting structure 222 through the protrusion 323 is switched to contacting the abutting structure 223 through the protrusion 324, so that the fulcrum of the key 2 is far away from the rotation axis of the key 2, the initial height h between the pressing center of the pressing sheet 22 and the micro switch is relatively reduced, and the pre-stressing of the key 2 is reduced, that is, the pressing hand feeling of the key 2 is lightened.

As can be seen from the above description, the pre-force adjusting structure 3 of the present invention mainly allows the user to switch one of the

protrusions

322, 323, 324 to abut against a corresponding one of the abutting

structures

221, 222, 223 through the rotation operation of the rotating handle 32, so as to adjust the pre-force required to be applied when pressing the touch key 2.

As shown in fig. 8 to 11, the mouse 100a includes a mouse body 1a, a button 2a and a preload adjustment structure 3a.

The mouse body 1a has a hinge region 11a and a pressing region 12a adjacent to each other, and the mouse body 1a further has two hinge structures 13a (only one is labeled in the figure) and a pressing column opening 14a. The two hinge structures 13a are disposed in the hinge area 11a at intervals, and the two hinge structures 13a are both open-loop structures in this embodiment. The pressing column hole 14a is opened in the pressing area 12a. In other embodiments, the pivot area 11a and the pressing area 12a are not necessarily adjacent to each other, and may be offset or spaced from each other.

The push button 2a includes a pivoting portion 21a and a pressing piece 22a. The pivoting portion 21a has two pivots 211a (only one is labeled in the figure), and the pivoting portion 21a is provided with an avoiding groove 212a; the two pivots 211a are respectively pivoted to the two pivoting structures 13a, and the avoiding groove 212a is located between the two pivots 211 a. The pressing piece 22a is integrally formed and extends from the pivot portion 21a, and the pressing piece 22a has a fastening structure 221a.

The preload adjusting mechanism 3a includes a base 31a, an elastic member 32a, and a rotation-driven linear motion assembly 33a.

The base 31a includes a base body 311a, a fixing bracket 312a, and a fixing shaft 313a. The base body 311a is integrally connected to the mouse body 1a, and the base body 311a is opened with four card holes 3111a (only one is labeled in the figure).

The fixing frame 312a includes a stem-limiting portion 3121a and a slider-limiting portion 3122a. The stem-limiting portion 3121a and the base body 311a enclose a stem-limiting space (not shown), and the stem-limiting portion 3121a further has two elastic hooks 31211a (only one is shown).

The sliding block limiting portion 3122a is integrally connected to the stem limiting portion 3121a, and forms a sliding block limiting space (not shown) communicating with the stem limiting space with the base body 311a, and the sliding block limiting portion 3122a further has two elastic hooks 31221a (only one is shown). The two elastic hooks 31211a and the two elastic hooks 31221a are used for being fastened to the four fastening holes 3111a, so that the fixing frame 312a can be detachably fixed to the base body 311a.

In addition, the sliding block limiting portion 3122a further has two pivot fixing portions 31222a (only one is labeled in the figures) and a limiting passage 31223a which are spaced apart from each other. The limiting channel 31223a is configured to enclose a slider limiting space with the base body 311a, and a plurality of guiding rib structures 312231a (only one is shown) are disposed in the limiting channel 31223a, and the guiding rib structures 312231a extend from a position adjacent to the stem limiting portion 3121a along an axial direction D1a (shown in fig. 12) and away from the stem limiting portion 3121a.

The fixed shaft 313a is fixed to the two pivot fixing portions 31222a.

The elastic element 32a includes a torsion spring body 321a, a first end 322a and a second end 323a. The torsion spring body 321a is rotatably disposed on the fixing shaft 313a and disposed between the two pivot fixing portions 31222a, so that the elastic element 32a is rotatably disposed on the fixing frame 312a. The first end 322a and the second end 323a respectively extend from two ends of the torsion spring body 321a, and the first end 322a is configured to abut against the pressing piece 22a and is limited by the fastening structure 221a. In addition, the first end 322a further has a bending positioning structure 3221a corresponding to the fastening structure 221a, so that the bending positioning structure 3221a is limited by the fastening structure 221a and is fixedly abutted against the pressing piece 22a. In the present embodiment, the elastic element 32a is a torsion spring, but is not limited thereto, and may be a spring plate or the like in other embodiments.

The rotary drive linear motion assembly 33a includes a stem 331a and a slider 332a. The stem 331a includes an operation portion 3311a, a rotation shaft portion 3312a, and a stopper ring 3313a. The operating portion 3311a is for the user to manually operate, the rotating shaft portion 3312a is formed by extending from the operating portion 3311a along the axial direction D1a and rotatably disposed through the slider limiting space, and the rotating shaft portion 3312a has an external thread structure 33121a. In this embodiment, since the two pivot structures 13a are disposed on two sides of the rotation shaft 3312a, in order to prevent the pivot portion 21a pivoted to the pivot structure 13a from hitting the rotation shaft 3312a during rotation, the pivot portion 21a is disposed to avoid the recess 212a to prevent the pivot portion 21a from hitting the rotation shaft 3312a during rotation.

The position-limiting ring 3313a is located between the operating portion 3311a and the external thread structure 33121a, and is rotatably disposed in the position-limiting groove 3112a, and further limited by the rotation-handle position-limiting space, so that the position-limiting rotation handle 331a is rotatably disposed between the base body 311a and the fixing frame 312a.

The sliding block 332a is movably disposed along the linear path P (shown in fig. 12) and abuts against the second end 323a in the sliding block spacing space, and the sliding block 332a further has an internal thread structure (not shown), so that the sliding block 332a is screwed to the external thread structure 33121a of the rotating shaft portion 3312a through the internal thread structure.

Referring to fig. 12 and 13, fig. 12 is a cross-sectional view of the cross-section D-D of fig. 8; FIG. 13 is a cross-sectional view of the handle of FIG. 12 rotated to drive the slider against the second end.

As shown in fig. 8 to 13, in the present embodiment, the handle 331a is rotatably disposed in the handle limiting space between the base body 311a and the fixing frame 312a, the sliding block 332a is movably disposed in the sliding block limiting space between the base body 311a and the fixing frame 312a along the linear path P, and the sliding block 332a is screwed to the handle 331a, so that when the handle 331a is rotated in the first rotating direction (not shown, for example, clockwise) by the rotating operation of the user, the screwed sliding block 332a is driven to rotate, but since the sliding block 332a is restricted by the sliding block limiting portion 3122a and cannot rotate, the sliding block 332a moves toward the axial direction D1a along the linear path P and pushes against the second end 323a.

As mentioned above, when the sliding block 332a moves along the linear path P toward the axial direction D1a and pushes the second end 323a, since the first end 322a and the second end 323a are integrally connected to the two ends of the torsion spring body 321a, respectively, the second end 323a pushed by the sliding block 332a drives the torsion spring body 321a to rotate, so that the pushing force of the first end 322a pushing the pressing piece 22a is increased, the initial height ha of the pressing piece 22a is increased, and the pre-force required to be applied when the touch key 2a is pressed is reduced. The initial height ha is a height at which the button 2a is not pressed, and is based on a distance from the pressing piece 22a to the microswitch 200a or from the pressing piece 22a to the upper surface of the mouse body 1a, for example.

On the other hand, when the handle 331a is rotated in a second rotation direction (not shown, for example, counterclockwise) opposite to the first rotation direction by the user, the slider 332a moves along the linear path P in the opposite direction of the axial direction D1a, and the pushing force applied to the second end 323a is relatively reduced, so that the pushing force applied to the pressing piece 22a by the first end 322a is reduced, and the initial height ha of the pressing piece 22a is correspondingly reduced.

As can be seen from the above description, the preload adjustment structure 3a of the present invention is mainly formed by screwing the rotating handle 331a and the sliding block 332a, and limiting the sliding block 332a from rotating through the sliding block limiting portion 3122a, so that when the rotating handle 331a is rotated, the screwed sliding block 332a converts the rotation motion into a linear motion and moves along the linear path P, and thereby the pushing force pushing against the second end 323a is changed, and the force of the first end 322a pushing against the pressing piece 22a is correspondingly changed, so that the initial height ha of the pressing piece 22a is correspondingly adjusted, thereby adjusting the preload required to be applied when the touch key 2a is pressed.

In addition, although in the embodiment, the rotation motion of the rotary handle 331a is converted into the linear motion of the sliding block 332a by the screw connection relationship between the rotary handle 331a and the sliding block 332a and the matching of the sliding block limiting portion 3122a, in other embodiments, the invention is not limited thereto, and the rotary handle 331a may be directly screw-connected to the base 31a, so that the rotary handle 331a itself may generate the linear motion by rotation, and the sliding block 332a may be connected to one end of the rotary handle 331a, so that the sliding block 332a is directly driven by the rotary handle 331a to linearly move.

In summary, the present invention mainly provides a plurality of protrusions on the rotating handle to allow the rotating handle to switch the protrusions abutting against the keys by rotation, so as to adjust the fulcrum positions abutting against the keys, or a screwing structure is used to convert the rotation of the rotating handle into the linear motion of the slider, so as to adjust the force of the elastic element pushing against the keys. Compared with the prior art that the feedback force of the mouse button is fixed, the mouse which meets the requirement can be selected by a user through actual operation, the button and the prestress adjusting structure can ensure that the user can automatically adjust the pressing operation force of the button, so that the user does not need to actually operate different mice to select the mouse which is suitable for the prestress of the button, the button can be freely adjusted to the pressing operation force which meets the requirement of the user, and the convenience in use is effectively improved.

In addition, because the key and the prestress adjusting structure can adjust the prestress force of the key by rotating the rotating handle, even if the mouse is used for a long time and generates elastic fatigue, the prestress can be increased by rotating the rotating handle, the service life of the mouse is effectively prolonged, the cost of a user for purchasing a new mouse is saved, and the waste of resources is relatively reduced. Furthermore, although the foregoing embodiments are exemplified by a mouse, the button and the preload adjusting structure of the present invention can be disposed on any electronic device, and are not limited to a mouse. In addition, in the aforementioned embodiment, the handle body of the preload adjusting structure is not perpendicular to the button, but disposed near the button at an angle and exposed on the upper surface of the mouse body, so that the user can conveniently adjust the preload of the button without flipping the mouse or detaching the button and/or the mouse component.
