In this present embodiment, there is the first spring 142 first spring constant, second spring 144 to have second spring constant, First spring constant is different from second spring constant, therefore, when receiving identical pressing force, the first spring 142 and the second bullet Spring 144 has different deflections, passes through the deformable amount of the first spring of design 142 and second spring 144 so that in keycap 122 When squeezing spring assembly, one of spring is first compacted.In this present embodiment, the first spring 142 with second spring 144 with phase With metal line footpath be made, the first spring 142 has a first external diameter 142a, and second spring 144 has a second external diameter 144a, first Outer diameter 142a is less than second external diameter 144a, the first spring 142 and 144 pitch having the same of second spring and length, therefore second Spring constant is less than the first spring constant, and second spring 144 will be first compacted.In addition, spring assembly includes connecting spring 146, the first spring 142 is connect with second spring 144 via connecting spring 146, and connecting spring 146 has the outer diameter of gradual change, makes It obtains the first spring 142 in 144 structure of second spring to be smoothly connected, and the power between the first spring 142 and second spring 144 Amount can be transmitted smoothly.In principle, the outer diameter of 146 gradual change of connecting spring is i.e. from first external diameter 142a gradual changes to second external diameter 144a Variation.In addition, in specific implementation, connecting spring 146 with for connector, such as a metal wire sections are in the side of spring assembly The both ends or two metal wire sections for connecting the first spring 142 and second spring 144 symmetrically connect the first bullet in two sides of spring assembly The both ends of spring 142 and second spring 144, and or a metal wire sections simultaneously across the first spring 142 and the end of second spring 144 Coil.In addition, in this present embodiment, the first spring 142 is coaxially disposed with second spring 144, i.e. the extension of the two structure is axial Overlapping, but invention is not limited thereto.Such as when the first spring 142 and 144 eccentric setting of second spring so that the first spring 142 can be directly connected to the both ends of second spring 144, that is, be not necessarily to connect through connecting spring 146, connecting spring 146 can at this time It omits.

In addition, before keycap 12 reaches conversion position, the whole coefficient of elasticity of spring assembly is the first spring constant Inverse and second spring constant reciprocal and inverse, so when whole coefficient of elasticity be less than the first spring constant and the Two spring constants, user can feel lighter feel i.e. smaller feedback force when pressing keycap 12, can be easily and rapidly Press keycap 12.It is postponed more than translation bit in keycap 12, because second spring 144 has been compacted, therefore whole coefficient of elasticity is equal to First spring constant；In other words, whole coefficient of elasticity increases.At this point, user can feel when pressing keycap 12 compared with The feel of weight, that is, larger feedback force, screen resilience are big.Therefore, during user presses keycap 12, user will feel To the feel of first light rear weight.In addition, in this present embodiment, the outer diameter 108a of pillar 108 is less than the second internal diameter of second spring 144 144b, the outer diameter 180a of pillar 108 are more than the first internal diameter 142b of the first spring 142, and the size of light source hole 1082 is less than first First internal diameter 142b of spring 142 so that pillar 108 can effectively the first spring of block 142 move down.When 12 rotation of keycap When change place to pressing position moves, that is, keycap 12 towards pedestal 10 movement be more than conversion position after, although second spring 144 Pillar 108 (as shown in Figure 7) is slightly protruded from relative to bottom plate 102 after being compacted, but the first spring 142 connects with second spring 144 The one end connect also can be against pillar 108, this contributes to the stability of 142 shell-shaped deformation of the first spring；But the present invention not as Limit.For example, 108 height of pillar is greatly reduced or is apparently higher than after so that second spring 144 is compacted pillar 108, the first spring 142 In principle would not be against pillar 108, but remain to move and flexible deformation towards bottom plate 102 with keycap 12.In addition, in specific In implementation, avoiding space can be formed on pillar 108, to avoid pillar 108 and 146 constructive interference of connecting spring, thereby, the second bullet Spring 144 can be less than pillar 108 after being compacted, and the first spring 142 remains to steadily against pillar 108.

In addition, based on the foregoing description, in specific implementation, spring assembly also can be changed so that the first spring 142 is in keycap During 12 are pressed, first reach compaction state, the same pressing feel that can realize first light rear weight.Such as by previous embodiment In spring assembly be inverted, you can the spring constant of the second spring 144 after making the spring of top be inverted is smaller, and first reaches Compaction state.Again or change length, line footpath, the pitch etc. of each spring, so that the spring of top is first reached compaction state, and not It is limited by first compacting with the spring with smaller spring constant；Similarly, this change means is equally applicable for aforementioned groups of springs Force mechanisms 14 are replied in conjunction so that second spring 144 can first reach the i.e. aforementioned compacting height H1 of compaction state.

In addition, in previous embodiment, the first spring 142 is concatenated with second spring 144 by the first spring 142 and second Spring 144 sequentially alinement and is connected, therefore keycap 12 is towards pedestal 10 when moving, to the force of spring assembly so that First spring 142 and second spring 144 are compressed；But invention is not limited thereto.As shown in figure 9, according to another implementation Example, the first spring 142 and second spring 144 side by side, but are still concatenation in structure, that is, the force of keycap 12 is still by the first bullet Spring 142 is transferred to second spring 144, then is transferred to pedestal 10.In in specific implementation, the first spring 142 in Fig. 9 and the second bullet Spring 144 is also able to nestable mode and is arranged, such as the first spring 142 has smaller outer diameter and can stretch into second spring 144, But concatenation must be still kept in structure.In Fig. 9, when keycap 12 is moved from initial position towards pedestal 10, the first spring 142 is Stretcher strain, second spring 144 are contracting compressive strains and can be depressed into its compression height by contracting.Likewise, being inverted about spring assembly Explanation, it is also applicable in this, do not repeat separately.

In press-key structure 1, the spring that spring assembly is concatenated with two is i.e. for example：First spring 142 and second of concatenation Spring 144, but invention is not limited thereto.In in specific implementation, spring assembly may include the spring of more concatenations so that bullet Multistage variation is presented in the coefficient of elasticity of spring composite entity, and each section of coefficient of elasticity is constant, and with compressed spring The coefficient of elasticity of the increase of quantity, spring assembly entirety also increases.In addition, the spring of each concatenation is not with single structure body Spring is limited, such as two and the spring that connects integrally can also be used as a spring concatenate herein in.In addition, in press-key structure 1 In, the second spring constant of second spring 144 is less than the first spring constant of the first spring 142, therefore in second spring 144 not by Before compacting, the coefficient of elasticity of spring assembly entirety is less than the second spring constant of second spring 144, and not in second spring 144 After being compacted, the coefficient of elasticity of spring assembly entirety is equal to the first spring constant of the first spring 142, and the first spring constant is more than The second spring constant of second spring 144, therefore user can feel that apparent feel difference pushes arrival in keycap 12 and turns Before change place and later.This feel difference also contributes to press-key structure 1 to provide position residing for user's keycap 12 by feedback force The information set, such as user can thereby know whether keycap 12 is effectively pressed generally, such as whether switch 18 is effective Triggering.

Please refer to Fig. 2, Fig. 4, Fig. 7 and Fig. 8.In this present embodiment, movable contact part 184 has fixing end 1842, freedom End 1844 and contact portion 1846, movable contact part 184 are fixed on bottom plate 102 via fixing end 1842, and contact portion 1846 is located at solid Between fixed end 1842 and free end 1844 and in electrical contact with fixed contact part 182.Trigger unit 1248 is via free end 1844 push movable contact part 184.

As shown in figure 4, when keycap 12 is not pressed and is located at initial position, movable contact part 184 is by trigger unit at this time 1248 push and flexible deformation have occurred, and such trigger unit 1248 pushes the free end 1844 of movable contact part 184, and to live The contact portion 1846 of movable contact part 184 and fixed contact part 182 separate, i.e., switch 18 keeps open circuit at this time.

As shown in fig. 6, when keycap 12 be pressed towards pedestal 10 and it is mobile be more than trigger position after, trigger unit 1248 with The free end 1844 of movable contact part 184 separately so that movable contact part 184 move because of screen resilience so that contact portion 1846 and Fixed contact part 182 contacts, i.e., switch 18 is connected at this time.In this present embodiment, trigger position is located at initial position (such as Fig. 4 institutes The person of showing) conversion position (person as shown in Figure 7) between so that after switch 18 be connected be in keycap 12 arrival trigger position it When, the contact portion 1846 of movable contact part 184 contacts fixed contact part 182, and keycap 12 still can not yet be pressed in second spring 144 Under real state, continue to be moved down into conversion position (person as shown in Figure 7).Such as it can design：The trigger bit for making switch 18 be connected Keycap 12 is set to from place of initial position moves downward 1.8~2.0mm, and the translation bit for making second spring 144 be compacted is set to Keycap 12 is from place of initial position moves downward 3.0~3.5mm.In this example, after the conducting of switch 18, keycap 12 may continue to After moving down at least 1mm, second spring 144 can be just compacted.

In this way, in keycap 12 from during initial position is moved to conversion position, spring assembly is replied force mechanisms 14 and is carried For smaller spring constant, therefore user's sense can be by lighter feel, and can quickly press keycap 12 and trigger switch 18； Also, when keycap 12 continues to move down up to pressing position, spring assembly, which changes, provides larger spring constant, and spring assembly is back Multiple force mechanisms 14 also provide larger screen resilience；User can be changed by the press sense of switch 18 by feel at this time, also Understand switch 18 to have been turned on, and finger is moved away from keycap 12 to stop applying pressing force so that keycap 12 can be rapidly back to In situ is initial position.This keystroke driving characteristic is unique：(1) before switch conduction, 14 spring constant of spring assembly is smaller, therefore makes User's finger experiences lighter resistance, and switch can comparatively fast be connected easily；(2) after switch conduction, more precisely, Yu Jian Cap 12 is more than the spring constant increasing of spring assembly after conversion position, therefore after user stops pressing, keycap 12 can be quickly Ground is back to initial position.So contribute to user with higher frequency pressing keys cap 12, such as in the computer of e-sports It in game, and is avoided that user's finger is excessively contributed again and rapid tired out, prolonged computer game manipulation can not be carried out.

In addition, in this present embodiment, movable contact part 184 is in opening up U-shaped structure, therefore cantilever design is substantially parallel Extend in 12 start direction of keycap, therefore movable contact part 184 there can be longer jib-length；In other words, movable contact part 184 Smaller trigger force is able to push.Also, for the centring point that movable contact part 184 deflects, 1248 contact terminal of trigger unit The position that the position (relative to distance L1) in portion 1846 contacts free end 1844 compared with fixed contact part 182 is (relative to distance L2) Far, that is, distance L1 is more than distance L2, therefore keycap 12 can penetrate lever principle, be touched with smaller via trigger unit 1248 It has an effect and opens the switch 18 of short circuit.In addition, even if there is a little variation in the position that trigger unit 1248 is contacted with movable contact part 184, Such as plunger 124 slightly has and is moved up and down on the bias relative to direction D1, this is changed to movable contact part 184 and fixed contact part The influence of 182 contact position will also be reduced, therefore fixed contact part 182 remains to connecing for effective movable contact part 184 in electrical contact Point portion 1846.In other words, the switch 18 of the present embodiment and the configuration of trigger unit 1248 help to promote the assembling to press-key structure 1 Or the tolerance of start error.In addition, in this present embodiment, when movable contact 184 start of part is substantially in horizontal deflection, trigger force Also it is in principle horizontal lateral force, helps to reduce the influence to keycap 12 relative to about 10 start of pedestal.

Please refer to Fig.1, Fig. 2, Fig. 5, Fig. 7 (or Fig. 8), Figure 10 and Figure 11, wherein in Figure 11, sliding connected structure 106, 1246, the profile of trigger unit 1248 and switch 18 is painted with dotted line.In this present embodiment, pedestal 10 has rectangular projection profile, Sequentially there is pedestal 10 first corner 10a, the second corner 10b, third corner 10c and fourth corner 10d, the sliding of pedestal 10 to hold in the mouth Binding structure 106 includes 2 first sliding components 1062, is shaped by taking sliding groove structure as an example, and with 104 structural integrity of upper cover.2 first Sliding component 1062 is located at the first corner 10a and third corner 10c.The sliding connected structure 1246 of keycap 12 includes 2 the Two sliding components 12462 correspond to the first corner 10a and third corner 10c respectively by taking slide block structure as an example.2 first sliding structures Part 1062 is combined slidably engaged with one another with 2 second sliding components 12462 so that keycap 12 is between initial position and pressing position Movement be linear movement or one-dimensional movement.Switch 18 is located at the second corner 10b, and trigger unit 1248 corresponds to the second corner 10b.Cause This, corner 10a, 10b, 10c that sliding connected structure 106,1246, trigger unit 1248 and switch 18 correspond to pedestal 10 respectively are set It sets, compared with other positions, such as side portion of the pedestal 10 between corner 10a, 10b, larger space setting can be enjoyed, into And provide the reliability and stability of structure start.In addition, in this present embodiment, the first sliding component 1062 with sliding groove structure and Second sliding component 12462 is illustrated by taking slide block structure as an example, but in specific implementation, can also exchanging setting, that is, first Sliding component 1062 by taking sliding groove structure as an example, can equally be combined slidably engaged with one another by slide block structure and the second sliding component 12462 And have effects that guide keycap 12 is moved up and down relative to pedestal 10.

As indicated above, in press-key structure 1, spring assembly is the process replied force mechanisms 14 and be used in flexible deformation In, so that one of spring i.e. second spring 144 is compacted and change its whole coefficient of elasticity, but the present invention not as Limit.2 to Figure 14 are please referred to Fig.1, for according to the continuous start section of pressing of a press-key structure 3 of another embodiment of the present invention Schematic diagram.Press-key structure 3 is roughly the same with 1 structure of press-key structure, therefore press-key structure 3 continues to use the component symbol of press-key structure 1, phase With the element function having the same of component symbol.Other than following the description, about other explanations of press-key structure 3, it please join The related description for readding press-key structure 1, does not repeat separately.Press-key structure 3 is with one of in place of 1 main difference of press-key structure by bond Structure 3 using stop part 109, (such as scheme certainly when keycap 12 is moved to conversion position from initial position towards pedestal 10 by press-key structure 3 The state that the state of 12 displays is shown to Figure 13), 14 constructive interference of force mechanisms is replied with spring assembly to prevent second spring 144 continue flexible deformations, rather than prevent the second spring 144 from continuing elastic change by way of so that second spring 144 is compacted Shape.Therefore, after keycap 12 is more than conversion position from initial position towards the movement of pedestal 10, stop part 109 and spring assembly Between generate constructive interference so that one of them can not be deformed for the first spring 142 and second spring 144, and the first spring 142 and Second spring 144 wherein it is another still can with keycap 12 towards pedestal 10 move and flexible deformation.Thereby, press-key structure 3 Spring assembly also can provide the lighter feel of user i.e. smaller feedback force, and in key before keycap 12 reaches conversion position Cap 12 is postponed more than translation bit, provides the heavier feel of user i.e. larger feedback force.In press-key structure 3, stop part 109 It is set to the bottom plate 102 of pedestal 10 and is equivalent to the pillar 108 of press-key structure 1, stop part 109 also has pillar 108 in button Effect in structure 1.In addition, furthermore, it is understood that in press-key structure 3, when keycap 12 is moved from initial position towards pedestal 10 More than conversion position after (state that such as press-key structure 3 is shown from the state that Figure 13 is shown to Figure 14), the first spring 142 against Stop part 109, this i.e. generate stop part 109 and spring assembly constructive interference effect so that second spring 144 can not again with Keycap 12 moves down and continues flexible deformation, but the first spring 142 is remained to as keycap 12 moves down and continues elastic change Shape.In addition, escape groove can be formed in specific implementation, on stop part 109 to accommodate connecting spring 146 so that the first spring 142 It can be more stably against stop part 109.In addition, in specific implementation, stop part 109 also can be by resisting connecting spring 146 Mode come prevent second spring 144 continue flexible deformation.As shown in figure 15, connecting spring 146 is against stop part 109 so that Two springs 144 do not continue to flexible deformation, but the first spring 142 remains to continue flexible deformation.Also, in Figure 15, connecting spring 146 can connect the both ends of the first spring 142 and second spring 144 for a metal wire sections in the side of spring assembly, or can be two Metal wire sections symmetrically connect the both ends of the first spring 142 and second spring 144 in two sides of spring assembly, and or can be a metal Line segment is simultaneously across the first spring 142 and the end coil of second spring 144.

In this present embodiment, stop part 109 is set to pedestal 10 with block second spring 144；But the present invention not as Limit.Such as be inverted the spring assembly of press-key structure 3, stop part 109, which changes, is set to plunger 124, at this point, this stop part 109 is It is the second spring 144 after being inverted for the spring above block.In another example as shown in figure 16, stop part 109' is set to key Cap 12 is provided between first spring 142 and second spring 144 for the supporting piece 143 with stop part 109' interactions, when keycap 12 When being moved downward to conversion position, stop part 109' is against supporting piece 143 so that the first spring 142 no longer with keycap 12 to Lower movement and deform, but second spring 144 is continued to as keycap 12 moves down and deforms.In in specific implementation, stop part 109', which can also change, to be set on pedestal 10 (person as shown in phantom in Figure 16)；At this point, when keycap 12 is moved downward to conversion position When, stop part 109' is against supporting piece 143 so that and second spring 144 is no longer as keycap 12 moves down and deforms, but first Spring 142 is continued to as keycap 12 moves down and deforms.In another example as shown in figure 17, stop part 109 " is set to keycap 12, when keycap 12 is moved down from initial position, the first spring 142 is stretcher strain, and second spring 144 is contracting compressive strain. When keycap 12 is moved downward to conversion position, stop part 109 is " against spring assembly or the first spring 142 and second spring 144 Junction so that the first spring 142 no longer as keycap 12 moves down and deforms, but second spring 144 continue to Keycap 12 is moved down and is deformed.In in specific implementation, stop part 109 " can also change and be set on pedestal 10 (dotted line in such as Figure 17 Those shown)；At this point, when keycap 12 is moved downward to conversion position, stop part 109 is " against spring assembly or the first spring 142 With the junction of second spring 144 so that second spring 144 is no longer as keycap 12 moves down and deforms, but the first spring 142 continue to as keycap 12 moves down and deforms.

Such as the explanation of aforementioned keys structure 1,3, either using makes the means that spring is compacted, or is kept off using stop part Only spring continues the means of deformation, and the two is that a spring in spring assembly is made to reach specific position such as in keycap in logic And flexible deformation mobile towards pedestal with keycap is not continued to when the conversion position, and then changes the whole elasticity system of groups of springs Number changes from small to big so that user can experience the feel of first light rear weight during pressing keycap.In keycap from beginning initial position When setting to conversion position, user experiences lighter feel, therefore user can quick pressing keys.It, can in specific implementation The switch triggering of press-key structure is set to be designed in this section of rank so that switch can be triggered rapidly.When keycap is more than conversion position, User experiences heavier feel, that is, keycap is at this time by larger screen resilience.When user no longer presses keycap, key Cap can promptly be sprung back, and keycap is pressed again with sharp user.In addition, in specific implementation, cooperation aforementioned switches triggering Design, when user experiences heavier feel, also can be known switch has been triggered, without excessively pressing keycap.

In addition, shrapnel 60 is slideably positioned in the shrapnel bearing 5024 of bottom plate 502, shrapnel bearing 5024 is located at accommodating space In 510, wherein shrapnel 60 includes sliding part 602, is connected to the elastic portion 604 of sliding part 602 and is set in elastic portion 604 There is sliding slot 5024a and upper surface 5024b, upper surface 5024b to be located at sliding slot 5024a's for protruding portion 604a, shrapnel bearing 5024 One end, shrapnel 60 are slidably disposed in sliding slot 5024a via sliding part 602 to be slideably positioned in shrapnel bearing 5024 (as shown in figure 19).Sliding part 602 has upper limb 602a and stop section 602b, the lower surface of upper limb 602a faces upper cover 504 5046, lower surface 5046 can block upper limb 602a to prevent sliding part 602 from continuing to slide up, stop section 602b faces upper surface 5024, upper surface 5024 can block stop section 602b with prevent sliding part 602 continue slide downward.Plunger 524 also includes to stir Portion 5246, selectively to push or stir the protruding portion 604a of shrapnel 60；When keycap 52 is moved up and down relative to pedestal 50 When, clicking section 5246 pushes protruding portion 604a so that 604 flexible deformation of elastic portion.

In this present embodiment, there is pedestal 50 rectangular projection profile (as shown in figure 20), pedestal 50 sequentially to have first jiao Fall 50a, the second corner 50b, third corner 50c and fourth corner 50d.The sliding connected structure 506 of pedestal 50 is located at first jiao 50a and third corner 50c is fallen, switch 58 is located at the second corner 50b, and shrapnel 60 is located at fourth corner 50d；The sliding of plunger 524 Connected structure 5242 corresponds to the first corner 50a and third corner 50c, and trigger unit 5244 corresponds to the second corner 50b, clicking section 5246 Corresponding fourth corner 50d.In this present embodiment, the movable contact part 584 of shrapnel 60 and switch 58 is oppositely arranged and is in cantilever Structure, therefore contribute to 524 stress balance of plunger.

Furthermore, it is understood that as shown in figure 21, keycap 52 is not pressed and is located at initial position.At this point, trigger unit 5244 passes through Movable contact part 584 is pushed by free end 5844 so that the contact portion 5846 of movable contact part 584 is divided with fixed contact part 582 It opens, protruding portion 604a of the clicking section 5246 not in contact with shrapnel 60.

As shown in figure 22, when keycap 52 is pressed and is moved downward to contact position, clicking section 5246 is with its lower inclined plane The top of the protruding portion 604a of 5246b contact flat springs 60.At this point, trigger unit 5244 still keeps pushing activity via free end 5844 Contact part 584 so that the contact portion 5846 of movable contact part 584 is still the state separated with fixed contact part 582.In addition, working as Keycap 52 is pressed and continues when moving down, and clicking section 5246 can be to the protruding portion 604a of shrapnel 60 via lower inclined plane 5246b It is power obliquely downwards to apply active force, that is, clicking section 5246 pushes protruding portion 604a obliquely downwards.But because of shrapnel 60 at this time The stop section 602b of sliding part 602 be resisted against on the upper surface 5024b of shrapnel bearing 5024, so active force is vertically downward Component will not be such that sliding part 602 is moved down relative to shrapnel bearing 5024, but this active force will make the elastic portion 604 of shrapnel 60 Flexible deformation due to pushings of the protruding portion 604a by clicking section 5246.

As shown in figure 23, when keycap 52 is pressed and continues to be moved downward to trigger position, contact portion 5846 just starts Contact fixed contact part 582；That is, keycap 52 is via 5244 trigger switch 58 of trigger unit.At this point, clicking section 5246 is under The protruding portion 604a that inclined-plane 5246b pushes shrapnel 60 makes the elastic portion 604 of shrapnel 60 generate flexible deformation, the top of clicking section 5246 Correct the top for pushing protruding portion 604a.In other words, (1) when keycap 52 be pressed decline reach the trigger position before, shrapnel 60 contact and push the lower inclined plane 5246b of clicking section 5246, and shrapnel 60 generates flexible deformation to a certain degree and via lower inclined plane 5246b applies active force, as oblique upward power, the component vertically upward of this active force to clicking section 5246；In principle will Keycap 52 is transferred to via plunger 524 to move downward to resist keycap 52, therefore can to experience one larger by pressure drag for user's finger Before power contacts protruding portion 604a compared to clicking section 5246.(2) continue to be less than trigger bit to movement when keycap 52 is pressed It postpones, clicking section 5246, which will change, to be pushed by its ramp 5246a below the protruding portion 604a of shrapnel 60；At this point, the bullet of shrapnel 60 Though property portion 604 is gradually replied, but still has flexible deformation, therefore shrapnel 60 can apply clicking section 5246 via ramp 5246a The vertical downward component of active force, i.e., power obliquely downwards, this active force in principle will be via plunger 524 to keycap 52 to assist Keycap 52 moves downward, and user's finger can be experienced smaller by pressure resistance.Such keycap 52 makes before and after by trigger position User's keycap to be pressed moves downward, and user's finger can experience pressing drag size significant change moment, and so providing makes User confirms the haptic feedback of the triggering and conducting of switch 58.

In addition, when clicking section 5246 is contacted with the protruding portion 604a of its ramp 5246a and shrapnel 60, clicking section 5246 Also active force, as oblique upward power, the component vertically upward of this active force are applied to shrapnel 60 via its ramp 5246a Drive the sliding part 602 of shrapnel 60 relative to 5024 upward sliding of shrapnel bearing.In this present embodiment, as shown in figure 24, it slides The upper limb 602a in portion 602 is against the lower surface 5046 of upper cover 504, even if clicking section 5246 is continued on through by 5246a pairs of its ramp Shrapnel 60 applies active force, will not also make 602 upward sliding of sliding part again.In other words, clicking section 5246 is oblique at this time supports upwards Push away protruding portion 604a so that sliding part 602 is moved up relative to sliding slot 5024a, and when upper limb 602a is against under upper cover 504 When surface 5046, the stopping of sliding part 602 moves up.Also, in this present embodiment, when the upper limb 602a of sliding part 602 is against upper When the lower surface 5046 of lid 504, clicking section 5246 will be disengaged from protruding portion 604a, therefore be detached from protruding portion 604a in clicking section 5246 Before, it is ensured that sliding part 602 can contact upper cover 504.And consider dynamically to interact start, principle between clicking section 5246 and shrapnel 60 On, sliding part 602 is to be resisted against the following table of upper cover 504 in such a way that its upper limb 602a hits the lower surface 5046 of upper cover 504 Face 5046, therefore can generate the sound, this sound are also available for users to the sense of hearing feedback for confirming the triggering and conducting of switch 58.In specific In implementation, it may be designed to when lower surfaces 5046 of the upper limb 602a of sliding part 602 against upper cover 504, elastic portion 604 still has Elastic deformation, that is, clicking section 5246 still exerts a force to shrapnel 60 via protruding portion 604a at this time, this can make the upper limb of sliding part 602 602a hits the lower surface 5046 of upper cover 504 with the strength of bigger, generates the sound of bigger.But the present invention is not limited. Such as if the sliding slot 5024a of the sliding part 602 of shrapnel 60 and shrapnel bearing 5024 is clearance cooperation, sliding part 602 can be easily It is slided in sliding slot 5024a, clicking section 5246 can accelerate sliding part 602 via ramp 5246a to the force of protruding portion 604a, So that sliding part 602 can have kinetic energy and can continue to upward sliding after clicking section 5246 is detached from protruding portion 604a on hitting The lower surface 5046 of lid 504, this can equally generate the sound, as sense of hearing feedback.

Then, as shown in figure 25, when keycap 52, which is pressed, to be continued to be moved downward to conversion position, clicking section 5246 is It is detached from 60 segment distance of shrapnel, shrapnel 60 hit the lower surface 5046 of upper cover 504 and send out the sound upwards by rebound.In other words, in Keycap 52 leaves trigger position before reaching conversion position, springs back shock upper cover 504 by shrapnel 60 and sends out the sound, so User can change through the thus sound, and obtain the sense of hearing feedback for confirming the triggering and conducting of switch 58.

Therefore, i.e. primary by trigger position via 5244 trigger switch 58 of trigger unit when keycap 52, by clicking section 5246 with the reciprocation of shrapnel 60, it is possible to provide drag size of user changes haptic feedback, with the sound at least once Sense of hearing feedback.

In addition, during 52 rotation change place of keycap returns to initial position, clicking section 5246 will also push prominent again Go out portion 604a, and power obliquely downwards can be applied to protruding portion 604a via lower inclined plane 5246b so that sliding part 602 can be opposite In sliding slot 5024a slide downwards.After keycap 52 returns to initial position, no matter at this time whether the stop section 602b of sliding part 602 Against the upper surface 5024b of shrapnel bearing 5024, when being pressed and moving down in next keycap 52,5246 equal energy of clicking section Power obliquely downwards is applied to protruding portion 604a with its lower inclined plane 5246b, the stop section 602b of sliding part 602 is made to be held against shrapnel The upper surface 5024b of seat 5024, and the aforementioned start of overline；It does not repeat separately.In addition, in this present embodiment, clicking section 5246 it is oblique Face 5246a, 5246b and protruding portion 604a itself can provide the force surface of skew force in cambered surface, therefore in specific implementation, it selects One design.Also, supplementary explanation, in the diagram about the present embodiment, bullet is touched on the top of clicking section 5246 just Property portion 604 surface, be considered as in principle do not make shrapnel 60 generate flexible deformation may be designed to clicking section in specific implementation Always retention gap between 5246 top and the surface of elastic portion 604, but invention is not limited thereto.In principle, the present embodiment The main driving force moved as shrapnel 60 with the interference generated when the relative movement of clicking section 5246 using protruding portion 604a, therefore in In specific implementation, even if clicking section 5246 does not include the part of protruding portion 604a also via elastic portion 604 itself, generate Perhaps deformation remains to make the upper limb 602a of sliding part 602 effectively to hit the lower surface 5046 of upper cover 504 and generate the sound.Such as To be configured to refer to shown in Figure 24, when clicking section 5246 be detached from protruding portion 604a when, upper limb 602a against or hit following table Face 5046, whether clicking section 5246 also pushes the part that elastic portion 604 does not include protruding portion 604a at this time, and shrapnel 60 generates bullet Property deformation, do not influence the fact that the sound has generated.

In addition, in this present embodiment, shrapnel 60 is cantilever design, the part of suspension substantially extends in vertical direction, but this Invention is not limited；For example, shrapnel changes for being horizontally inserted into the metal plate of pedestal 50, the part of horizontal suspended can It is interactive to generate feel variation and the sound with clicking section 5246.

Keycap is set on the pedestal, which there are two second sliding components, two second sliding component to correspond to respectively First corner and the third corner, the keycap include trigger unit and clicking section, which corresponds to second corner, this is stirred Portion corresponds to the fourth corner, which is combined slidably engaged with one another with second sliding component so that the keycap is in first Beginning position and pressing position between movement be linear movement；

Spring is connected between the keycap and the pedestal so that when the keycap does not bear pressing force, which is positively retained at The initial position；

Switch, is fixedly installed on the pedestal, which includes fixed contact part and the movable contact part being oppositely arranged, this is opened Off-position is in second corner；And

Shrapnel corresponds to the fourth corner and is set to the pedestal；

Wherein when the keycap is located at the initial position, which pushes the movable contact part and makes the movable contact part and be somebody's turn to do Fixed contact part separates；

Wherein when the keycap bears pressing force it is mobile towards the pedestal and before reaching trigger position, the clicking section it is oblique to Under push the shrapnel；

Wherein after the keycap continues to move down and move more than the trigger position, which separates with the movable contact part So that movable contact part movement is with the fixed contact part to contact, and the clicking section is oblique pushes the shrapnel upwards.

34. press-key structure as claimed in claim 33, which is characterized in that the shrapnel includes sliding part, is connected to the sliding part Elastic portion and be set to the protruding portion of the elastic portion, which includes shrapnel bearing, which has sliding slot and upper table Face, the shrapnel are slidably disposed in the sliding slot via the sliding part to be slideably positioned in the shrapnel bearing, the sliding part With upper limb, which, which corresponds to the upper limb, has lower surface, and when the keycap is moved up and down relative to the pedestal, which supports The protruding portion is pushed away so that the elastic portion flexible deformation.

35. press-key structure as claimed in claim 34, which is characterized in that when the keycap continues to move down from the trigger position When, the clicking section is oblique to push the protruding portion upwards so that the sliding part is moved up relative to the sliding slot, and when the upper limb supports When by the lower surface of the pedestal, sliding part stopping moves up.

36. press-key structure as claimed in claim 35, which is characterized in that when the upper limb being somebody's turn to do against the pedestal of the sliding part When lower surface, the upper limb of the sliding part hits the lower surface of the pedestal and sends out the sound.
