Wherein, in hinge arms 32 by external force and when opposite from hinge seat 31 is rotated, by 322 He of the first supporting surface The junction 324 of second supporting surface 323 pushes supporting element 34 to overcome the elastic biasing of elastic component 35 and move backward, so that Third supporting surface 341 from one of the first supporting surface 322 and the second supporting surface 323 elasticity abuts be switched to and first support The other of face 322 and the second supporting surface 323 elasticity abut.

In an application scenarios, elastic component 35 is arranged in towards one end of hinge arms 32 in the connection of supporting element 34, and makes Third supporting surface 341 is towards 32 side of hinge arms, in by external force and around the shaft 31 turns of the 33 opposite from hinge seat of hinge arms 32 In dynamic process, third supporting surface 341 can be pushed and supporting element 34 is made to oppress elastic component 35, and further in elastic component 35 Under the action of elastic biasing occurs.Certainly, supporting element 34 can also be not connected to elastic component 35, and be only to be connected to supporting element 34 side, as long as supporting element 34 is enabled to realize above-mentioned elastic biasing.

Wherein, the first supporting surface 322 and the second supporting surface 323 be respectively the adjacent of hinge arms 32 and at least partly with turn Two sides of the axis parallel of axis 33 or a part of two sides are rotated in 32 opposite from hinge seat 31 of hinge arms When, the first supporting surface 322 and the second supporting surface 323 rotate with hinge arms 32 around shaft 33, so that hinge arms 32 Not ipsilateral towards hinge seat 31 so that hinge arms 32 can have different relative positions to close relative to hinge seat 31 System.

In addition, elastic component 35 is to be capable of providing elastic force and can compress on elastic force direction to provide certain compression space Component.For example, elastic component 35 can be spring, one end of spring abuts supporting element 34, in the third supporting surface of supporting element 34 341 by impetus towards elastic component 35 when, elastic component 35 revolts supporting element 34 and compression occurs simultaneously to be supporting element 34 341 directions of third supporting surface direction on space is provided so that when the relative position of shaft 33 is constant, still have enough The space side that makes hinge arms 32 different turn between shaft 33 and third supporting surface 341.

Specifically, when hinge arms 32 are rotated relative to hinge seat 31, the relative position of shaft 33 does not change, hinge Arm 32 and the contact position of the third supporting surface 341 of hinge seat 31 change, and since the different positions of hinge arms 32 are arrived The distance of shaft 33 is different, therefore, such as the first supporting surface 322 and the second supporting surface 323 in the different positions of hinge arms 32 When different location and third supporting surface 341 contact, the contact of the shaft 33 of the needs to hinge arms 32 and third supporting surface 341 Space between point is different.And limited by elastic force effect and space etc., the space that elastic component 35 is compressed and provided may be It is limited.Therefore, during hinge arms 32 are rotated relative to hinge seat 31, in the section of the central axes perpendicular to shaft 33 If a certain position is excessive at a distance from shaft 33 in upper hinge arms 32, which will be fastened in third support during rotation Another location on face and hinge arms 32 can not be made to continue to rotate so that hinge arms 32 and hinge seat 31 only can be one It is relatively rotated in fixed range.In an application scenarios, 33 relatively rotated around the shaft between hinge arms 32 and hinge seat 31 During, the only company of the first supporting surface 322 and the second supporting surface 323 and the first supporting surface 322 and the second supporting surface 323 Connecing region corresponding to place 324 can abut with third supporting surface 341.

Further, in present embodiment, the first supporting surface 322 and the second supporting surface 323 can be plane, shaft 33 Distance to the junction of the two 324 be all larger than the 33 to the first supporting surface of shaft 322 distance and to second supporting surface 323 away from Can have that third supporting surface 341 is connected to the first supporting surface 322 and third supporting surface 341 is connected to second from, hinge 30 323 two kinds of support face relatively steady state.

Certainly, in the present embodiment, the first supporting surface 322 and the second supporting surface 323 are also likely to be with certain radian Curved surface, even may also include different sub- supporting surfaces, as long as the position between hinge arms 32 and hinge seat 31 is enabled to close System has corresponding at least two relatively steady state, is not specifically limited herein.In addition, can be in hinge arms 32 Other more supporting surfaces are set, to be relatively rotated between 33 and hinge seat 31 around the shaft in hinge arms 32 by external force When, elasticity is occurred with third supporting surface 341 by supporting surface different in hinge arms 32 and is abutted so that hinge arms 32 and hinge There are a variety of different relative positional relationships between seat 31, be not specifically limited herein.

It specifically, is for the first supporting surface 322 is abutted with the third supporting surface 341 of supporting element 34, to have by original state Body is as shown in Figures 10 and 11.Elastic component 35 can have elastic compression deformation at this time, also may be at original natural shape State, herein without limitation.Occur that hinge arms 32 33 relatively with hinge seat 31 around the shaft in hinge 30 When being rotated such that the second supporting surface 323 moves closer to third supporting surface 341, the first supporting surface 322 and the second supporting surface 323 Junction 324 is contacted with third supporting surface 341, is turned since the distance of junction 324 to shaft 33 is arrived greater than the first supporting surface 322 The distance of axis 33, so that junction 324 abuts supporting element 34 and the mobile direction towards elastic component 35 of supporting element 34 is pushed to move It is dynamic, so that elastic component 35 overcomes thrust and generates compression.And in 32 further stress of hinge arms, junction 324 is gradually Close to the region between third supporting surface 341 of shaft 33, in the process, between shaft 33 to third supporting surface 341 Distance is gradually increased；Ground is readily appreciated that, when the line of junction 324 and shaft 33 is perpendicular to third supporting surface 341, vertical In on the section of the central axes of shaft 33, the distance of shaft 33 to third supporting surface 341 be equal to shaft 33 to junction 324 away from From shaft 33 is farthest apart from third supporting surface 341 at this time；And at this moment, if continuing to exert a force to hinge 30, shaft 33 arrives third The distance of supporting surface 341 will gradually become smaller, so that the space that required elastic component 35 compresses reduces, and so that elasticity Part 35 gradually discharges elastic force and replys, and until third supporting surface 341 is left in junction 324 and makes the second supporting surface 323 and Three supporting surfaces 341 abut, and abut to the second supporting surface 323 and the to realize from the first supporting surface 322 and third supporting surface 341 Switching between three supporting surfaces 341 abutting.

Similarly, original state for the second supporting surface 323 is abutted with the third supporting surface 341 of supporting element 34 and to first Supporting surface 322 abutted with the third supporting surface 341 of supporting element 34 conversion process (specifically as shown in figure 13 and figure 14) with it is upper It is similar to state process.

It should be pointed out that the hinge 30 in present embodiment can be applied to the hinge set in the application glasses embodiment In part 122.In an application scenarios, functor 20 is osteoacusis loudspeaker mechanism 21, in third supporting surface 341 from first One of supporting surface 322 and the second supporting surface 323 elasticity, which abut, to be switched to and the first supporting surface 322 and the second supporting surface 323 The other of elasticity when abutting, hinge component 122 drives osteoacusis loudspeaker mechanism 21 can be the relative to temple main body 121 It is switched between one fixed position relative and the second fixed position relative, and is in first relatively in osteoacusis loudspeaker mechanism 21 The auricle back side of user can be fitted in when fixed position.

Specifically, first fixed position relative such as in Figure 15 institute of the osteoacusis loudspeaker mechanism 21 relative to temple main body 121 Show, the second fixed position relative relative to temple main body 121 is as shown in fig. 1.

Wherein, auricle is a part of external ear, is mainly made of cartilage.In present embodiment, loudspeaker mechanism is conformed to The auricle back side, and then bond-conduction sound/vibration is transmitted using the cartilage of auricle.Loudspeaker mechanism is closed in dorsum auriculae face paste, While improving sound quality, additionally it is possible to reduce the influence in sound transmittance process to ear canal.

It should be pointed out that the distance of shaft 33 to junction 324 is all larger than to the first supporting surface 322 and the second supporting surface 323 vertical range so that third supporting surface 341 from one of the first supporting surface 322 and the second supporting surface 323 Elasticity abut be switched to the other of the first supporting surface 322 and the second supporting surface 323 elasticity abut during hinge 30 State a degree of jump occurs.

It is abutted with the first supporting surface 322 with 341 elasticity of third supporting surface and is switched to the second supporting surface 323 and third supporting surface For 341 elasticity abut, shaft 33 arrives the maximum distance h of junction 324₁With the most short distance of the 33 to the first supporting surface of shaft 322 From h₂Between ratio difference when, the degree of the jump generated in handoff procedure is different.

In one embodiment, on the section of the central axes perpendicular to shaft 33, shaft 33 arrives the maximum of junction 324 Distance h₁With the shortest distance h of the 33 to the first supporting surface of shaft 322₂Between ratio between 1.1 and 1.5.

Specifically, can and by shaft 33 far from the second supporting surface 323 the close hinge opposite with the second supporting surface 323 The one side of chain arm 32 is arranged, and Lai Shixian shaft 33 arrives the maximum distance h of junction 324₁Greater than the 33 to the first supporting surface of shaft 322 shortest distance h₂, and then meet aforementioned proportion.

It is pointed out that h₁With h₂Between ratio it is excessive when, jump is obvious, but may need to apply biggish power First supporting surface 322 can be abutted with 341 elasticity of third supporting surface and be switched to the second supporting surface 323 and third supporting surface by degree 341 elasticity abut, to make troubles to a certain extent for use；And h₁With h₂Between ratio it is too small when, although state Switching is relatively easy to, but it is smaller to jump degree, such as does not have apparent sense of touch when user pulls hinge 30, thus It can make troubles.In present embodiment by h₁With h₂Ratio setting be between 1.1 and 1.5, enable to third to support Face 341 from is abutted with the elasticity of the first supporting surface 322 be switched to abutted with 323 elasticity of the second supporting surface when, hinge 30 with compared with Significantly to jump, so that in use, user has more apparent feel when pulling hinge 30, while also not It is too lofty as transitional states and user is made to be difficult to switch the state of hinge 30.

In an application scenarios, h₁With h₂Ratio can also be between 1.2 and 1.4, specifically, h₁With h₂Ratio Example can also be 1.1,1.2,1.3,1.4,1.5 etc., be not specifically limited herein.

In addition, the setting of the position of the first supporting surface 322 and the second supporting surface 323 in hinge arms 32 will affect third branch Folder when support face 341 is abutted with one of the first supporting surface 322 or the second supporting surface 323 between hinge arms 32 and hinge seat 31 The angle at angle therefore can be according to specific use demand, and to the first supporting surface 322 and the second supporting surface 323 in hinge arms 32 On position carry out different settings.Wherein, the angle between hinge arms 32 and hinge seat 31 specifically as depicted in figure 10 and figure 13, ω₁Angle when being abutted for third supporting surface 341 with the first supporting surface 322 between hinge arms 32 and hinge seat 31, ω₂For third Angle when supporting surface 341 is abutted with the second supporting surface 323 between hinge arms 32 and hinge seat 31.In one embodiment, it cuts with scissors Chain arm 32 and hinge seat 31 all have certain length, and the end one on the length direction of hinge seat 31 is arranged in hinge arms 32 Side, the end on 32 length direction of hinge arms close to hinge seat 31 is arranged in the first supporting surface 322, and the second supporting surface 323 is set One end in 32 width direction of hinge arms is set, and is arranged each parallel to the central axes of shaft 33.At this point, working as third supporting surface 341 with the elasticity of the first supporting surface 322 when abutting, the angle maximum between hinge arms 32 and hinge seat 31, and in third supporting surface 341 with the elasticity of the second supporting surface 323 when abutting, and the angle between hinge arms 32 and hinge seat 31 is minimum, thus in third support Face 341 from is abutted with the elasticity of the first supporting surface 322 be switched to the second supporting surface 323 is elastic abut when, hinge seat 31 and hinge Angle between arm 12 is by ω₁Become ω₂And become smaller.

It is further noted that if third supporting surface 341 is switched to from abutting with the elasticity of the first supporting surface 322 and The direction for the power that hinge arms 32 are applied when second supporting surface, 323 elasticity abuts and the direction one of 32 self gravity of hinge arms Cause, then when the switching meeting of the state is so that the angle between hinge seat 31 and hinge arms 12 becomes smaller, in present embodiment on State h₁With h₂Between the setting of ratio be also possible that when 322 elasticity of third supporting surface 341 and the first supporting surface abuts, cut with scissors Chain arm 32 will not or be difficult to spontaneous because of self gravity must reduce its angle between hinge seat 31.

Wherein, in one embodiment of the application hinge, Figure 12 is please referred to, in the section of the central axes perpendicular to shaft 33 On, the angle ω between the first supporting surface 322 and the second supporting surface 323₃For obtuse angle.

Wherein, hinge 30 is from the state that 341 elasticity of the first supporting surface 322 and third supporting surface abuts to the second supporting surface When 323 states abutted with 341 elasticity of third supporting surface switch, the angle between the first supporting surface 322 and the second supporting surface 323 ω₃It is smaller, then it is bigger relative to the angle for needing to rotate between hinge seat 31 and hinge arms 32 when state switches, that is to say, that When hinge seat 31 is fixed, user, which needs to pull hinge arms 32 biggish angle, to cut 30 carry out state of hinge It changes, so that user is laborious to use, makes troubles to user's use.

And since hinge arms 32 have certain length, and the first supporting surface 322 is set to the length direction of hinge arms 32 On one end, and the second supporting surface 323 is disposed adjacent with the first supporting surface 322 in the width direction of hinge arms 32.Usual feelings Under condition, the first supporting surface 322 is vertically arranged with the second supporting surface 323, at this point, carrying out between above two state in hinge 30 When switching, need hinge arms 32 and hinge seat 31 pulling 90 ° relatively.

And in present embodiment, on the section of the central axes perpendicular to shaft 33, the first supporting surface 322 and the second support Angle ω between face 323₃For obtuse angle, thus when hinge 30 switches between two states, institute's hinge arms 32 and hinge seat The opposite angle pulled is less than 90 ° required for 31, so as to provide convenience to a certain extent for user.

Specifically, when hinge 30 in the present embodiment is in the application glasses embodiment, hinge 30 is for connecting Temple main body 121 and osteoacusis loudspeaker mechanism 21 are connect, is in the second supporting surface 323 and 341 elasticity of third supporting surface in hinge 30 When the second state abutted, osteoacusis loudspeaker mechanism 21 is in the first fixed position relative to fit in the auricle back side of user, Therefore when user needs the function using the osteoacusis loudspeaker mechanism 21 of glasses, it is only necessary to rotate osteoacusis loudspeaker mechanism 21 Angle less than 90 ° can be fitted in the auricle back side of user；In addition, being in the first supporting surface 322 and in hinge 30 When the first state that three supporting surfaces, 341 elasticity abuts, the osteoacusis loudspeaker mechanism 21 of hinge arms 32 and connection forms certain angle Degree, so that the osteoacusis loudspeaker mechanism 21 of hinge arms 32 and connection can be located at after user's ear and court in user's wearing spectacles It is arranged to the direction of user's ear, so as to play certain obstruction, fixed function to glasses, is not easy to fall from user's head It falls.

It should be pointed out that the angle ω between the first supporting surface 322 and the second supporting surface 323₃Specific angle can be with It is set according to actual needs.When the angle of the angle is excessive, hinge arms 32 and hinge arms 32 are connected to far from hinge seat Angle between the functor 20 and hinge seat 31 of 31 end will be smaller, thus when user wears, hinge arms 32 and function Part 20 can cause to oppress due to too close to user's ear to user's ear, reduce the comfort level of user；And if the angle of angle It is too small, one side user pull osteoacusis loudspeaker mechanism 21 and make its between the first relative position and the second relative position into When row switching, the required angle pulled is excessive, and user is inconvenient to use, on the other hand, temple main body 121 and hinge 30 and bone It is smaller and be difficult to play the role of obstruction, the fixation to glasses that angle is formed by between conduction loudspeaker mechanism 21, so that When user's wearing spectacles, glasses are easy to fall on front side of user's head.Specifically, first can be arranged according to the head dummy of user The specific angle of angle between support face 322 and the second supporting surface 323.

Specifically, in an application scenarios, on the section of the central axes perpendicular to shaft 33, the first supporting surface 322 And the second angle ω between supporting surface 323₃Angle between 100 ° and 120 °, be specifically as follows 100 °, 110 °, 120 ° Deng.The setting of the angle, enables to user in wearing spectacles and osteoacusis loudspeaker mechanism 21 is in the first fixed position relative When, osteoacusis loudspeaker mechanism 21 will not cause discomfort too close to user's ear and to user's ear, and to osteoacusis loudspeaking Without hinge to be rotated to excessive angle when two kinds of relative positions of mechanism 21 switch over, thus user-friendly.

Wherein, it is abutted in third supporting surface 341 from one of the first supporting surface 322 and the second supporting surface 323 elasticity It is switched in the process abutted with the other of the first supporting surface 322 and the second supporting surface 323 elasticity, the first supporting surface 322 and the second junction 324 between supporting surface 323 abut third supporting surface 341, and supporting element 34 is pushed to overcome elastic component 35 Elastic biasing and move backward.For switching preceding third supporting surface 341 and be abutted with 322 elasticity of the first supporting surface, initial When switching, while the first supporting surface 322 is gradually distance from third supporting surface 341, junction 324 gradually abuts third supporting surface 341, and in handoff procedure, the other side of third supporting surface 341 is slid by the side of third supporting surface 341, most laggard one Step, which is transitted to, to be abutted by the second supporting surface 323 with 341 elasticity of third supporting surface.In stateful switchover process, junction 324 is always It abuts and interacts with third supporting surface 341, and the shape of junction 324 can generate certain shadow to stateful switchover process It rings.For example, if line connects between the first supporting surface 322 and the second supporting surface 323, then, junction 324 has more sharp Angle, to be pulled in the stateful switchover process of hinge seat 31 and/or hinge arms 32 to carry out hinge 30 in user, on the one hand, Junction 324 abut with third supporting surface 341 abutted with junction 324 with the first supporting surface 322 and the second supporting surface 323 into When row switching, buffering is smaller, and switching is lofty, so that the feel for pulling hinge 30 is poor；On the other hand, junction 324 is more sharp, Certain abrasion can be caused to third supporting surface 341 in handoff procedure repeatedly.

And in one embodiment of the application, on the section of the central axes perpendicular to shaft 33, junction 324 is arc-shaped to be set It sets.So that the first supporting surface 322 is that cambered surface is connect, and then is cut in the state of hinge 30 with the connection of the second supporting surface 323 In the process changed, the junction 324 abutted with third supporting surface 341 is more smooth, so that user has when pulling hinge 30 Preferable feel, and the damage in handoff procedure repeatedly to third supporting surface 341 can be reduced.

Specifically, in one embodiment, junction 324 is arranged in circular arc, and the curvature of circular arc is different, brought by Effect is also different, and specific curvature value needs that actual use situation is combined to be configured.The curvature of circular arc is situated between in present embodiment It specifically can also be 5,10,15,20,25,30 etc., herein without limitation between 5 and 30.

It should be pointed out that when hinge 30 in the present embodiment is applied to the glasses in above-mentioned glasses embodiment, The curvature of the junction 324 of circular arc setting enables to user pulling hinge 30 so that bone-conduction speaker is opposite first When switching between fixed position and the second fixed position relative, there is preferable feel.

In one embodiment, third supporting surface 341 be arranged so that third supporting surface 341 from the first supporting surface 322 elasticity abut be switched to external force required when being abutted with the elasticity of the second supporting surface 323 different from third supporting surface 341 from Second supporting surface, 323 elasticity, which abuts, is switched to external force required when abutting with 322 elasticity of the first supporting surface.

It should be pointed out that in specific usage scenario, hinge 30 corresponding to the different state of hinge 30 or The function of the structure that hinge 30 is connected is different, or due to the position problems that hinge 30 is arranged, and make a certain state to Another state is not easy to the reasons such as user's force, and needs when state of the user to hinge 30 switches over when switching over It is distinguished in the dynamics for pulling hinge 30, to facilitate user to exert a force, or distinguishes two kinds of hinge states for user and provide directly The impression etc. of sight.

Specifically, when hinge 30 in the present embodiment is applied in above-mentioned glasses, the switching of 30 state of hinge can band Dynamic osteoacusis loudspeaker mechanism 21 relative to temple main body 121 between the first fixed position relative and the second fixed position relative into Row switching.Accordingly, two kinds of fixed position relatives respectively correspond user using osteoacusis loudspeaker mechanism 21 and user without using bone 21 two kinds of situations of loudspeaker mechanism are conducted, and user is in wearing spectacles, hand is applied when back head exerts a force to switch two states The complexity of power is not identical, is accordingly the external force being necessary to apply different by the switched design of different conditions therefore, can Aspect user uses.

Specifically, in one embodiment, when third supporting surface 341 is switched to from elastic abut of the first supporting surface 322 When being abutted with the elasticity of the second supporting surface 323, pulled by the second fixed position relative to the corresponding to by osteoacusis loudspeaker mechanism 21 One fixed position relative is to fit in the auricle back side of user.

Further, in present embodiment, third supporting surface 341 is arranged so that in third supporting surface 341 from first 322 elasticity of supporting surface, which abuts, is switched to external force required when abutting with 323 elasticity of the second supporting surface less than in third supporting surface 341 From is abutted with the elasticity of the second supporting surface 323 be switched to the first supporting surface 322 is elastic abut when required external force.

It should be pointed out that when using osteoacusis loudspeaker mechanism 21, being needed third branch when being applied to above-mentioned glasses Support face 341 is abutted with 323 elasticity of the second supporting surface from abutting to be switched to the elasticity of the first supporting surface 322, and is not using bone biography When leading loudspeaker mechanism 21, need for third supporting surface 341 to be switched to and third supporting surface from elastic abut of the second supporting surface 323 341 elasticity abut, and according to the present embodiment, when user is using osteoacusis loudspeaker mechanism 21, the power of required application is less than and is not required to The power applied required for osteoacusis loudspeaker mechanism 21 is used, so as to the bone of user-friendly glasses to a certain extent Conduct the function of loudspeaker mechanism 21.

Specifically, also referring to Figure 12 and Figure 14, in an application scenarios, in third supporting surface 341 from first 322 elasticity of supporting surface is abutted to when abutting switching with 323 elasticity of the second supporting surface, and the initial contact of junction 324 is supported in third The first position 3411 in face 341, third supporting surface 341 from abutted with 323 elasticity of the second supporting surface to the first supporting surface 322 Elasticity abut switching when, junction 324 initially contact in the second position of third supporting surface 341 3412, wherein perpendicular to turn On the section of the central axes of axis 33, first position 3411 is with the contact point of elastic component 35 and supporting element 34 along the elasticity of elastic component 35 Distance d in biased direction₁Less than the second position 3412 with contact point the distance d along elastic biasing direction₂。

It should be pointed out that when third supporting surface 341 and 322 elasticity of the first supporting surface are supported, junction 324 is located at close to the The position of one end of three supporting surfaces 341, and when third supporting surface 341 is abutted with 323 elasticity of the second supporting surface, junction 324 Positioned at the position of the other end close to third supporting surface 341.Therefore, above-mentioned first position 3411 and the second position 3412 are distinguished Positioned at the both ends of third supporting surface 341.That is, in present embodiment, the third supporting surface 341 of supporting element 34 By the position of two close end at a distance from the contact point of elastic component 35 and supporting element 34 is on the elastic biasing direction of elastic component 35 not Together, and the corresponding distance in the second position 3412 is less than the corresponding distance in first position 3411.At this point, third supporting surface 341 from It is abutted with 322 elasticity of the first supporting surface to when abutting switching with the elasticity of the second supporting surface 323, junction 324 is initially not immediately Third supporting surface 341 and the reaction force by elastic component 35 are abutted, but gradually abuts third support during switching Face 341 and the reaction force by elastic component 35；And third supporting surface 341 from abutted with 322 elasticity of the first supporting surface to When the elasticity of second supporting surface 323 abuts switching, junction 324 is initial just abut third supporting surface 341 and by elastic component 35 Reaction force, or at least relative to third supporting surface 341 from abutted with 323 elasticity of the second supporting surface to the first supporting surface 322 elasticity abut switchings will early by elastic component 35 reaction force.Therefore, in this case, hinge 30 is by with first 322 elasticity of supporting surface abut to is abutted with the elasticity of the second supporting surface 323 switch when required active force it is smaller so that with The power of family application required for pulled osteoacusis loudspeaker mechanism 21 when using osteoacusis loudspeaker mechanism 21 is smaller, to facilitate use Family uses.

Further, third supporting surface 341 includes the first sub- supporting surface 3413 and the second sub- supporting surface 3414, wherein first Position 3411 is set to the first sub- supporting surface 3413, and the second position 3412 is set to the second sub- supporting surface 3414.I.e. first son branch Support face 3413 and the second sub- supporting surface 3414 are respectively arranged at the position close to the both ends of third supporting surface 341.

Wherein, the second sub- supporting surface 3414 can be plane, specifically, in the first supporting surface 322 or the second supporting surface 323 When abutting with 341 elasticity of third supporting surface, the second sub- supporting surface 3414 can be flat with the first supporting surface 322 or the second supporting surface 323 Row.And the first sub- supporting surface 3413 can be plane, or cambered surface, herein without limitation.

Further, the first sub- supporting surface 3413 and the second sub- supporting surface 3414 be not in the same plane, the first son branch Support face 3413 is obliquely installed relative to the second sub- supporting surface 3414, and angle between the two can be not more than 10 °, such as can be No more than 2 °, 4 °, 6 °, 8 °, 10 ° etc..Specifically, the first sub- supporting surface 3413 is directed away from the direction setting of hinge arms 32, from And make on the section of the central axes perpendicular to shaft 33, the contact point of first position 3411 and elastic component 35 and supporting element 34 Distance on the elastic biasing direction of elastic component 35 be less than the second position 3412 and contact point on elastic biasing direction away from From.Wherein, the first sub- supporting surface 3413 be cambered surface and the second sub- supporting surface 3414 be plane when, the first sub- supporting surface 3413 with Angle between second sub- supporting surface 3414 is the intersection and the tangent plane and second of the first sub- supporting surface 3413 in the two Angle between sub- supporting surface 3414.

It is the detonation configuration figure of one embodiment of the application hinge further referring to Figure 16, Figure 16.In present embodiment, Hinge seat 31 includes seat ontology 313 and from the protrusion of seat ontology 313 and the first lug 314 being intervally installed and the second lug 315, hinge arms 32 include that arm body 325 and the third lug 326 from the protrusion setting of arm body 325, third lug 326 are inserted into Interval region to first lug 314 and the second lug 315, and pass through shaft 33 and first lug 314 and the second lug 315 rotation connections, the first supporting surface 322 and the second supporting surface 323 are set on third lug 326, and supporting element 34 is at least partly It is set in interval region and is located at third lug 326 towards the side of seat ontology 313, be provided with and be spaced on seat ontology 313 The accommodating cavity 3121 of regional connectivity, elastic component 35 are set in accommodating cavity 3121, and by supporting element 34 towards third lug 326 into Row elastic biasing.

Specifically, the corresponding position of first lug 314, the second lug 315 and third lug 326 can be respectively arranged with position In first through hole, the second through-hole and third through-hole in same axial direction, the internal diameter of three through-holes can be outer not less than shaft 33 Diameter, thus 31 energy of hinge seat when shaft 33 is arranged in corresponding through-hole, where first lug 314 and the second lug 315 Enough hinge arms 32 with where third lug 326 are rotatably connected.
