Referring to Fig. 2, Fig. 4, Fig. 7 and Fig. 8.In the present embodiment, the first spring 142 and second spring 144 are straight line Contact and be arranged in accommodation space 110, as shown in Figure 4 by precompressed；Now, keycap 12 be located at initial position, keycap 12 not by Pressing.When keycap 12 bears pressing force via cap body 122 and moves towards base 10 from initial position, for example user is with handss Refer to pressing cap body 122, keycap 12 is replied force mechanisms 14 applying pressing force and is depicted with arrows in figure, pressing force to spring assembly Sequentially it is transferred to base 10 via the first spring 142 and second spring 144.Reach dislocation in keycap 12 (as shown in Figure 7 Person) before, the first spring 142 and second spring 144 all can with keycap 12 with respect to the movement of base 10 and elastic deformation.Work as key Cap 12 moves to during dislocation, and second spring 144 is compressed into corresponding compacting height h1, as shown in Figure 7.Now, second The a plurality of elastic ring substantial orthogonality stacking of spring 144, that is, adjacent elastic ring contact make between the two no can ammunition feed Property deformation gap, even if therefore second spring 144 bears bigger power again, also cannot produce elastic deformation, that is, second spring 144 cannot be again by compressive deformation.In the present embodiment, in second spring 144, adjacent elastic ring is pressed in vertical direction It is in close contact in contracting, flexible direction and make between the two tight.Therefore, when keycap 122 movement exceed dislocation it Afterwards, second spring 144 no longer deformation, the first spring 142 then still can move and elastic deformation towards base 10 with keycap 12.In In the present embodiment, when keycap 122 continuously moves to pressing position, the first spring 142 is also compressed into corresponding compacting height, As shown in Figure 8；But the present invention is not limited, such as press-key structure 1 also may be designed to when keycap 122 is located at pressing position, First spring 142 is not compacted and elastically deformable.

In the present embodiment, the first spring 142 has the first spring constant, and second spring 144 has 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, by designing the deformable amount of the first spring 142 and second spring 144 so that in keycap 122 During extrusion spring combination, one of spring is first compacted.In the present embodiment, the first spring 142 and second spring 144 are with phase Same metal line footpath is made, and the first spring 142 has first external diameter 142a, and second spring 144 has second external diameter 144a, and first External diameter 142a is less than second external diameter 144a, and the first spring 142 has identical pitch and length with second spring 144, therefore second Spring constant is less than the first spring constant, and second spring 144 is first compacted.Additionally, spring assembly comprises connecting spring 146, the first spring 142 is connected via connecting spring 146 with second spring 144, and connecting spring 146 has the external diameter of gradual change, makes Obtain the first spring 142 can smoothly be connected with second spring 144 structure, and the power between the first spring 142 and second spring 144 Amount can smoothly be transmitted.In principle, the external diameter of connecting spring 146 gradual change is i.e. from the gradual change of first external diameter 142a to second external diameter 144a Change.In addition, on being embodied as, connecting spring 146 must think connector, such as one metal wire sections are in the side of spring assembly Connect the two ends of the first spring 142 and second spring 144, or two metal wire sections are in the symmetrical connection in two sides first bullet of spring assembly Spring 142 and the two ends of second spring 144, and or metal wire sections simultaneously across the end of the first spring 142 and second spring 144 Coil.In addition, in the present embodiment, the first spring 142 and second spring 144 are coaxially disposed, i.e. the extension axial direction of both structures Overlap, but the present invention is not limited.For example when the first spring 142 with second spring 144 eccentric setting so that the first spring 142 can be directly connected to the two ends of second spring 144, need not connect through connecting spring 146, now connecting spring 146 can Omit.

Additionally, reaching before dislocation in keycap 12, the coefficient of elasticity of the entirety of spring assembly is the first spring constant Inverse and second spring constant inverse and inverse, so when overall coefficient of elasticity be less than the first spring constant and the Two spring constants, user can feel that lighter feel is less feedback force when pressing keycap 12, can be easily and rapidly Pressing keycap 12.After keycap 12 exceedes dislocation, because second spring 144 is compacted, therefore the coefficient of elasticity of entirety is equal to First spring constant；In other words, overall coefficient of elasticity increased.Now, user can be felt relatively when pressing keycap 12 The feel of weight is larger feedback force, and resilience force is big.Therefore, during user presses keycap 12, user will be felt To the feel first gently weighing afterwards.In addition, in the present embodiment, the external diameter 108a of projection 108 is less than the second internal diameter of second spring 144 144b, the external diameter 180a of projection 108 are more than the first internal diameter 142b of the first spring 142, light source hole 1082 be smaller in size than first First internal diameter 142b of spring 142 is so that projection 108 can block the first spring 142 move down effectively.When keycap 12 rotation Change place to pressing position mobile when be after keycap 12 exceedes dislocation towards base 10 movement although second spring 144 Slightly protrude from projection 108 (as shown in Figure 7) with respect to base plate 102 after being compacted, but the first spring 142 is with second spring 144 even The one end connecing also can be against projection 108, and this contributes to the degree of stability of the first spring 142 shell-shaped deformation；But the present invention not as Limit.For example, apparently higher than projection 108 after projection 108 height is greatly reduced or so that second spring 144 is compacted, the first spring 142 Would not against projection 108, but remain to move and elastic deformation towards base plate 102 with keycap 12 in principle.In addition, in concrete In enforcement, projection 108 can form avoidance space, to avoid projection 108 and connecting spring 146 constructive interference, thereby, the second bullet Spring 144 can be less than projection 108 after being compacted, and the first spring 142 remains to stably against projection 108.

In addition, being based on preceding description, on being embodied as, also spring assembly can be changed so that the first spring 142 is in keycap During 12 are pressed, first reach compaction state, equally enable the pressing feel first gently weighing afterwards.For example 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 less, and first reaches Compaction state.Again or change the length of each spring, line footpath, pitch etc., the spring of top also can be made first to reach compaction state, and not It is limited by first compacting with the spring with less spring constant；Similarly, this change means is equally applicable for aforementioned groups of springs Force mechanisms 14 are replied so that it is aforementioned compacting height h1 that second spring 144 can first reach compaction state in conjunction.

In addition, in previous embodiment, the first spring 142 is concatenated the first spring 142 and second with second spring 144 Spring 144 sequentially alinement being connected, thus keycap 12 in towards base 10 mobile when, the force to spring assembly so that First spring 142 and second spring 144 are all compressed；But the present invention is not limited.As shown in figure 9, according to another enforcement Example, the first spring 142 with second spring 144 side by side, but is 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 base 10.On being embodied as, the first spring 142 in Fig. 9 and the second bullet Spring 144 is also able to nestable mode and arranges, and the such as first spring 142 has less external diameter and can stretch in second spring 144, But still must keep in structure concatenating.In Fig. 9, when keycap 12 moves from initial position towards base 10, the first spring 142 is Stretcher strain, second spring 144 be contractive pressure deformation and can be by contractive pressure to its compression height.Likewise, being inverted with regard to spring assembly Explanation, also applicable in this, separately do not repeat.

In press-key structure 1, spring assembly with two concatenation springs i.e. for example: the first spring 142 and second of concatenation Spring 144, but the present invention is not limited.On being embodied as, spring assembly can comprise the spring of more concatenations so that bullet The coefficient of elasticity of spring composite entity assumes multistage change, and each section of coefficient of elasticity is all constant, and with the spring being compressed The increase of quantity, the overall coefficient of elasticity of spring assembly also increases.Additionally, the spring of each concatenation is not with single structure body Spring is limited, one of such as two and the spring that connects integrally can act also as concatenating herein spring.Additionally, 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 overall coefficient of elasticity of spring assembly is less than the second spring constant of second spring 144, and in second spring 144 not After being compacted, the overall coefficient of elasticity of spring assembly 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 obvious feel difference pushes arrival in keycap 12 and turns Before change place and afterwards.This feel difference also contributes to press-key structure 1 provides position residing for user keycap 12 by feedback force The information put, such as user thereby can know whether keycap 12 is effectively pressed generally, and for example whether switch 18 is effective Triggering.

Refer to Fig. 2, Fig. 4, Fig. 7 and Fig. 8.In the present embodiment, movable contact part 184 has fixing end 1842, freedom End 1844 and contact portion 1846, movable contact part 184 is fixed on base 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 promotion movable contact parts 184.

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

As shown in fig. 6, after keycap 12 is pressed towards base 10 and movement exceedes trigger position, trigger unit 1248 with The free end 1844 of movable contact part 184 so that movable contact part 184 is moved because of resilience force so that contact portion 1846 with Fixed contact part 182 contacts, i.e. now switch 18 conducting.In the present embodiment, trigger position is located at initial position (as Fig. 4 institute The person of showing) and dislocation (person as shown in Figure 7) between so that when switch 18 conducting after i.e. in keycap 12 reach trigger position it When, the contact portion 1846 contact fixed contact part 182 of movable contact part 184, keycap 12 still not yet can be pressed in second spring 144 Under real state, continue to be moved down into dislocation (person as shown in Figure 7).For example can design: make the trigger bit that switch 18 turns on It is set in place of keycap 12 moves downward 1.8～2.0mm from initial position, and make the dislocation that second spring 144 is compacted be In place of keycap 12 moves downward 3.0～3.5mm from initial position.In this example, after switch 18 conducting, keycap 12 may continue to After moving down at least 1mm, second spring 144 just can be compacted.

So, during keycap 12 is from initial position movement to dislocation, spring assembly is replied force mechanisms 14 and is carried For less spring constant, therefore user sense can be subject to lighter feel, and can quickly press keycap 12 trigger switch 18； Also, when keycap 12 continues to move down and reaches pressing position, spring assembly changes provides larger spring constant, spring assembly returns Multiple force mechanisms 14 also provide larger resilience force；Now user can be changed by feel, also by switching 18 press sense Understand that switch 18 has been turned on, and finger is moved apart keycap 12 to stop applying pressing force so that keycap 12 can rapidly be back to Original position is initial position.This keystroke driving characteristic is unique: (1), before switch conduction, spring assembly 14 spring constant is less, therefore makes User's finger experiences lighter resistance, comparatively fast can turn on switch easily；(2) after switch conduction, more precisely, Yu Jian After cap 12 exceedes dislocation, the spring constant of spring assembly increases, therefore after user stops pressing, keycap 12 can be quick Be back to initial position.So help to user is with higher frequency pressing keys cap 12, such as in the computer of e-sports In game, and be avoided that user finger excessively to exert oneself again and tired out rapidly it is impossible to carry out long computer game manipulation.

Additionally, in the present embodiment, movable contact part 184 is in opening up u shape structure, therefore cantilever design is almost parallel Extend in keycap 12 start direction, therefore movable contact part 184 can have longer jib-length；In other words, movable contact part 184 It is able to less trigger force to promote.Also, for the centring point of movable contact part 184 deflection, trigger unit 1248 contact terminal The position (with respect to apart from l2) that the position (with respect to apart from l1) in portion 1846 contacts free end 1844 compared with fixed contact part 182 is Far, that is, be equivalent to and be more than apart from l2 apart from l1, therefore keycap 12 can pass through lever principle, touched with less via trigger unit 1248 Have an effect and open the switch 18 of short circuit.Even if additionally, there is a little variation the position that trigger unit 1248 is contacted with movable contact part 184, Such as plunger 124 slightly has and moves up and down with respect to direction d1 on the bias, and this changes to movable contact part 184 and fixed contact part The impact of 182 contact position also will be reduced, therefore fixed contact part 182 remains to connecing of 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 contribute to lifting the assembling to press-key structure 1 Or the tolerance of start error.In addition, in the present embodiment, being in substantially horizontal deflection during movable contact part 184 start, trigger force In principle also be horizontal side force, contribute to reduce to keycap 12 with respect to base start about 10 impact.

Refer to Fig. 1, Fig. 2, Fig. 5, Fig. 7 (or Fig. 8), Figure 10 and Figure 11, wherein in Figure 11, slip connected structure 106, 1246th, the profile of trigger unit 1248 and switch 18 is illustrated with dotted line.In the present embodiment, base 10 has rectangular projection profile, Base 10 sequentially has the first corner 10a, the second corner 10b, the third angle fall 10c and fourth corner 10d, the slip rank of base 10 Access node structure 106 comprises 2 first sliding components 1062, and shapes with upper lid 104 structural integrity taking sliding groove structure as a example.2 first Sliding component 1062 is located at the first corner 10a and the third angle respectively and falls 10c.The slip connected structure 1246 of keycap 12 comprises 2 Two sliding components 12462, correspond to the first corner 10a and the third angle respectively and fall 10c taking slide block structure as a example.2 first slip structures Part 1062 is combined so that keycap 12 is between initial position and pressing position slidably engaged with one another with 2 second sliding components 12462 Motion 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 slip connected structure 106,1246, trigger unit 1248 and switch 18 correspond to base 10 respectively set Put, compared with other positions, such as side portion between corner 10a, 10b for the base 10, larger space setting can be enjoyed, enter And reliability and the degree of stability of structure start are provided.In addition, in the present embodiment, the first sliding component 1062 with sliding groove structure and Second sliding component 12462 illustrates taking slide block structure as a example, but on being embodied as, also can exchange setting, that is, first Sliding component 1062, equally can be combined by slide block structure and the second sliding component 12462 taking sliding groove structure as a example slidably engaged with one another And have functions that guide keycap 12 moves up and down with respect to base 10.

As indicated above, in press-key structure 1, spring assembly replys the process that force mechanisms 14 are used in elastic deformation In so as in a spring be that second spring 144 is compacted and changes its overall coefficient of elasticity, but the present invention not as Limit.Refer to Figure 12 to Figure 14, it is the pressing continuous start section of the press-key structure 3 according to another embodiment of the present invention Schematic diagram.Press-key structure 3 is roughly the same with press-key structure 1 structure, therefore press-key structure 3 continues to use the component symbol of press-key structure 1, phase With the element of component symbol, there is identical function.In addition to the description below, with regard to other explanation of press-key structure 3, please join Read the related description of press-key structure 1, separately do not repeat.It is by bond one of in place of press-key structure 3 and press-key structure 1 main difference Structure 3 utilizes stop part 109 (if press-key structure 3 is from figure when keycap 12 moves to dislocation from initial position towards base 10 The state that the state of 12 displays shows to Figure 13), reply force mechanisms 14 constructive interference to stop second spring with spring assembly 144 continuation elastic deformations, rather than to stop second spring 144 to continue elasticity change by way of making second spring 144 and being compacted Shape.Therefore, when keycap 12 is from after initial position exceedes dislocation towards base 10 movement, stop part 109 and spring assembly Between produce constructive interference so that the first spring 142 and second spring 144 one of them cannot deform, and the first spring 142 and Second spring 144 is wherein another still can be moved and elastic deformation towards base 10 with keycap 12.Thereby, press-key structure 3 Spring assembly also can reach before dislocation in keycap 12, and the feel providing user lighter is less feedback force, and in key After cap 12 exceedes dislocation, the feel providing user heavier is larger feedback force.In press-key structure 3, stop part 109 The base plate 102 being arranged at base 10 and the projection 108 being equivalent to press-key structure 1, stop part 109 also has projection 108 in button Effect in structure 1.Additionally, furthermore, it is understood that in press-key structure 3, when keycap 12 is mobile towards base 10 from initial position After exceeding dislocation (state showing from the state that Figure 13 shows to Figure 14 as press-key structure 3), the first spring 142 against Stop part 109, this produce stop part 109 and spring assembly constructive interference effect so that second spring 144 cannot again with Keycap 12 moves down and continues elastic deformation, but the first spring 142 remains to move down with keycap 12 and continues elasticity change Shape.Additionally, on being embodied as, stop part 109 can form escape groove to accommodate connecting spring 146 so that the first spring 142 Can be more stably against stop part 109.In addition, on being embodied as, stop part 109 also can be by propping up connecting spring 146 Mode come to stop second spring 144 continue elastic deformation.As shown in figure 15, connecting spring 146 is against stop part 109 so that Two springs 144 do not continue to elastic deformation, but the first spring 142 remains to continue elastic deformation.Also, in Figure 15, connecting spring 146 two ends that can connect the first spring 142 and second spring 144 for metal wire sections in the side of spring assembly, or can be two Metal wire sections are in the symmetrical two ends connecting 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 end coil of the first spring 142 and second spring 144.

In the present embodiment, stop part 109 is arranged at base 10 with block second spring 144；But the present invention not as Limit.For example the spring assembly of press-key structure 3 is inverted, stop part 109 changes and is arranged at plunger 124, and now, this stop part 109 is Second spring 144 after being inverted for the spring above block.Again for example, as shown in figure 16, stop part 109' is arranged at key Cap 12, is provided with for the supporting piece 143 interactive with stop part 109', when keycap 12 between the first spring 142 and second spring 144 When being moved downward to dislocation, stop part 109' against supporting piece 143 so that the first spring 142 no longer with keycap 12 to Lower movement and deform, but second spring 144 continues to move down with keycap 12 and deforms.On being embodied as, stop part 109' also can change and is arranged at (as shown in phantom in Figure 16) on base 10；Now, when keycap 12 is moved downward to dislocation When, stop part 109' against supporting piece 143 so that second spring 144 no longer moves down with keycap 12 and deforms, but first Spring 142 continues to move down with keycap 12 and deforms.Again for example, as shown in figure 17, stop part 109 " is arranged at keycap 12, when keycap 12 moves down from initial position, the first spring 142 is stretcher strain, and second spring 144 is contractive pressure deformation. When keycap 12 is moved downward to dislocation, 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 moves down with keycap 12 and deforms, but second spring 144 continue to Keycap 12 moves down and deforms.On being embodied as, stop part 109 " also can change and be arranged on base 10 (as dotted line in Figure 17 Those shown)；Now, when keycap 12 is moved downward to dislocation, stop part 109 is " against spring assembly or the first spring 142 With the junction of second spring 144 so that second spring 144 no longer moves down with keycap 12 and deforms, but the first spring 142 continue to move down with keycap 12 and deform.

As the explanation of aforementioned keys structure 1,3, either using the means making spring be compacted, or kept off using stop part Only spring continues the means of deformation, and both are all to make one of spring assembly spring reach ad-hoc location such as in keycap in logic Do not continue to during this dislocation move and elastic deformation towards base with keycap, and then change the overall elasticity system of groups of springs Number changes from small to big so that user, during pressing keycap, can experience the feel first gently weighing afterwards.In keycap ad initio initial position Put to during dislocation, user experiences lighter feel, therefore user can quick pressing keys.On being embodied as, can The switch triggering of press-key structure is made to be designed in this section of rank being triggered rapidly so that switching.When keycap exceedes dislocation, User experiences heavier feel, that is, keycap is now subject to larger resilience force.When user no longer presses keycap, key Cap can promptly resilience, keycap is pressed again with sharp user.Additionally, on being embodied as, cooperation aforementioned switches triggering Design, when user experiences heavier feel, also can be known switch is triggered, and need not excessively press keycap.

Additionally, shell fragment 60 is slideably positioned in the shell fragment bearing 5024 of base plate 502, shell fragment bearing 5024 is located at accommodation space In 510, wherein shell fragment 60 comprises sliding part 602, connects to the elastic 604 of sliding part 602 and be arranged in elastic 604 Protuberance 604a, shell fragment bearing 5024 has chute 5024a and upper surface 5024b, and upper surface 5024b is located at chute 5024a's One side, shell fragment 60 is slidably disposed in chute 5024a via sliding part 602 to be slideably positioned in shell fragment bearing 5024 (as shown in figure 19).Sliding part 602 has upper limb 602a and stop section 602b, the lower surface just to upper lid 504 for the upper limb 602a 5046, lower surface 5046 can block upper limb 602a to stop sliding part 602 from continuing to slide up, stop section 602b is just to upper surface 5024, upper surface 5024 can block stop section 602b with stop sliding part 602 continue slide downward.Plunger 524 also comprises to stir Portion 5246, in order to optionally to push or to stir the protuberance 604a of shell fragment 60；When keycap 52 moves up and down with respect to base 50 When, clicking section 5246 pushes protuberance 604a so that elastic 604 elastic deformation.

In the present embodiment, base 50 has rectangular projection profile (as shown in figure 20), and base 50 sequentially has first jiao 50a, the second corner 50b, the third angle of falling falls 50c and fourth corner 50d.The slip connected structure 506 of base 50 is located at first jiao Fall 50a and the third angle falls 50c, switch 58 is located at the second corner 50b, and shell fragment 60 is located at fourth corner 50d；The slip of plunger 524 The corresponding first corner 50a of connected structure 5242 and the third angle fall 50c, and trigger unit 5244 corresponds to the second corner 50b, clicking section 5246 Corresponding fourth corner 50d.In the present embodiment, shell fragment 60 is oppositely arranged and all in cantilever with the movable contact part 584 of switch 58 Structure, therefore contribute to plunger 524 stress balance.

Furthermore, it is understood that as shown in figure 21, keycap 52 is not pressed and is located at initial position.Now, trigger unit 5244 warp Movable contact part 584 is pushed by free end 5844 so that the contact portion 5846 of movable contact part 584 and 582 points of fixed contact part Open, clicking section 5246 is not in contact with the protuberance 604a of shell fragment 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 protuberance 604a of 5246b contact flat spring 60.Now, trigger unit 5244 still keeps pushing activity via free end 5844 Contact part 584 is so that the contact portion 5846 of movable contact part 584 and fixed contact part 582 are still the state separated.Additionally, working as Keycap 52 be pressed and continuous continue when moving down, clicking section 5246 can be to the protuberance 604a of shell fragment 60 via lower inclined plane 5246b To apply active force i.e. power obliquely downwards, that is, clicking section 5246 pushes protuberance 604a obliquely downwards.But shell fragment 60 when therefore The stop section 602b of sliding part 602 be resisted against on the upper surface 5024b of shell fragment bearing 5024, so active force is vertically downward Component will not make sliding part 602 move down with respect to shell fragment bearing 5024, but this active force will make the elastic 604 of shell fragment 60 The elastic deformation because protuberance 604a is subject to the pushing of 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 trigger unit 5244 trigger switch 58.Now, clicking section 5246 by under The protuberance 604a that inclined-plane 5246b pushes shell fragment 60 makes the elastic 604 of shell fragment 60 produce elastic deformation, the top of clicking section 5246 Correct the top pushing protuberance 604a.In other words, (1) when keycap 52 be pressed decline reach this trigger position before, shell fragment 60 contact and push the lower inclined plane 5246b of clicking section 5246, and shell fragment 60 produces to a certain degree elastic deformation via lower inclined plane 5246b is to clicking section 5246 to apply active force, as oblique power upwards, the component vertically upward of this active force；In principle will Be transferred to keycap 52 via plunger 524 to move downward to resist keycap 52, thus user finger can experience one larger by pressure drag Before power is compared to clicking section 5246 contact protuberance 604a.(2) continue to mobile and be less than trigger bit when keycap 52 is pressed Postpone, clicking section 5246 is pushed changing below the protuberance 604a of shell fragment 60 by its ramp 5246a；Now, the bullet of shell fragment 60 Though property portion 604 is gradually replied, but still has elastic deformation, therefore shell fragment 60 can apply to clicking section 5246 via ramp 5246a Active force, i.e. power obliquely downwards, the vertical downward component of this active force in principle will be via plunger 524 to keycap 52 to assist Keycap 52 moves downward, user finger can experience less by pressure resistance.So keycap 52, before and after by trigger position, makes User's keycap to be pressed moves downward, and user finger can experience pressing drag size significant change moment, and so providing makes User confirms the haptic feedback of switch 58 triggering and conducting.

Additionally, when clicking section 5246 is contacted with the protuberance 604a of shell fragment 60 with its ramp 5246a, clicking section 5246 Also via its ramp 5246a to shell fragment 60 to apply active force, as oblique power upwards, the component vertically upward of this active force The sliding part 602 ordering about shell fragment 60 is with respect to shell fragment bearing 5024 upward sliding.In the present embodiment, as shown in figure 24, slide The upper limb 602a in portion 602 is against the lower surface 5046 of upper lid 504, even if clicking section 5246 continues on through by its ramp 5246a pair Shell fragment 60 to apply active force, also will not make sliding part 602 upward sliding again.In other words, now clicking section 5246 is oblique supports upwards Push away protuberance 604a so that sliding part 602 moves up with respect to chute 5024a, and under upper limb 602a is against upper lid 504 During surface 5046, sliding part 602 stops moving up.Also, in the present embodiment, when the upper limb 602a of sliding part 602 is against upper During the lower surface 5046 of lid 504, clicking section 5246 will be disengaged from protuberance 604a, therefore departs from protuberance 604a in clicking section 5246 Front it is ensured that sliding part 602 can contact lid 504.And consider dynamically to interact start, principle between clicking section 5246 and shell fragment 60 On, sliding part 602 is the following table being resisted against upper lid 504 in the way of the lower surface 5046 of lid 504 on its upper limb 602a shock Face 5046, therefore can produce the sound, this sound is also available for users to the audition feedback confirming switch 58 triggering and conducting.In concrete In enforcement, may be designed to upper limb 602a when sliding part 602 against upper lid 504 lower surface 5046 when, elastic 604 still has Elastic deformation, that is, now clicking section 5246 still exerts a force to shell fragment 60 via protuberance 604a, this can make the upper limb of sliding part 602 602a clashes into the lower surface 5046 of lid 504 with bigger strength, produces the bigger sound.But the present invention is all not limited. If the sliding part of such as shell fragment 60 602 is clearance cooperation with the chute 5024a of shell fragment bearing 5024, sliding part 602 can be easily Slide in chute 5024a, clicking section 5246 can accelerate sliding part 602 via ramp 5246a to the force of protuberance 604a, So that sliding part 602 can be had kinetic energy and upward sliding can be continued to on clash into after clicking section 5246 departs from protuberance 604a The lower surface 5046 of lid 504, this equally can produce the sound, as audition feedback.

Then, as shown in figure 25, when keycap 52 is pressed and continues to be moved downward to dislocation, clicking section 5246 is Depart from shell fragment 60 segment distance, shell fragment 60 upwards resilience clash on lid 504 lower surface 5046 and send the sound.In other words, in Keycap 52 leaves trigger position and before reaching dislocation, clashing into lid 504 by shell fragment 60 resilience sends the sound, so User through being changed by this sound, and can obtain the audition feedback confirming switch 58 triggering and conducting.

Therefore, when keycap 52 via trigger unit 5244 trigger switch 58 i.e. through trigger position once, by clicking section 5246 with the reciprocal action of shell fragment 60, it is possible to provide drag size of user changes haptic feedback, with the sound at least one times Audition feedback.

In addition, during keycap 52 returns to initial position from dislocation, clicking section 5246 also will push prominent again Go out portion 604a, and via lower inclined plane 5246b, power obliquely downwards can be applied so that sliding part 602 can be relatively to protuberance 604a In chute 5024a slide downward.After keycap 52 returns to initial position, no matter now whether the stop section 602b of sliding part 602 Against the upper surface 5024b of shell fragment bearing 5024, when next keycap 52 is pressed and moves down, all can in clicking section 5246 Power obliquely downwards is applied to protuberance 604a with its lower inclined plane 5246b, so that the stop section 602b of sliding part 602 is held against shell fragment The upper surface 5024b of seat 5024, and the aforementioned start of overline；Separately do not repeat.In addition, in the present embodiment, clicking section 5246 oblique Face 5246a, 5246b and protuberance 604a itself all can provide the force surface of skew force in cambered surface, therefore on being embodied as, select One designs.Also, supplementary notes, in the diagram with regard to the present embodiment, bullet is touched on the top of clicking section 5246 just Property portion 604 surface, be considered as not making shell fragment 60 to produce elastic deformation in principle, on being embodied as, may be designed to clicking section All the time retention gap between the surface of 5246 top and elastic 604, but the present invention is not limited.In principle, the present embodiment Main by the use of protuberance 604a with clicking section 5246 relative movement when the driving force interfered as shell fragment 60 movement that produces, therefore in It is embodied as, even if clicking section 5246, also via elastic 604 itself, does not include the part of protuberance 604a, produces The deformation permitted, remains to make the effective lower surface 5046 clashing into lid 504 of upper limb 602a of sliding part 602 and produces the sound.For example To be configured to reference shown in Figure 24, when clicking section 5246 departs from protuberance 604a, upper limb 602a against or clash into following table Face 5046, now clicking section 5246 whether also push the part that elastic 604 does not include protuberance 604a, and shell fragment 60 produce bullet Property deformation, the fact that all do not affect the sound and produce.

In addition, in the present embodiment, shell fragment 60 is cantilever design, the part of suspension substantially extends in vertical direction, but this Invention is not limited；For example, as a example shell fragment changes the metal plate to be horizontally inserted base 50, the part of its horizontal suspended can With clicking section 5246 interaction to produce feel change and the sound.

The foregoing is only present pre-ferred embodiments, all impartial changes done according to scope of the present invention patent with repair Decorations, all should belong to the covering scope of the present invention.
