First embodiment

Referring to Fig. 1, the dotted line on the figure neutron arm of force 121 represents the line of demarcation between each section, the shape of each section is simultaneously It is undesired completely with consistent in figure, the shape of each section only plays the effect of signal in figure.In figure between the 2 strip arm of forces 121 Straight dotted line represents the line of symmetry of arm of force component 120, while being also the line of symmetry of inner ring 110.

A kind of spring 100 is present embodiments provided, which is cone spring.The spring 100 mainly applies to polygon In vertical linearity vibrating motor 200.Spring 100 includes inner ring 110 and 2 arm of force components for being connected to 110 periphery of inner ring 120.Arm of force component 120 includes 2 sub- arm of forces 121 being symmetrically set.In this way, 121 quantity of the sub- arm of force of spring 100 is 4 A, 121 quantity of the sub- arm of force is more, and during spring 100 vibrates, the internal stress per the strip arm of force 121 is smaller, the vibrating fatigue longevity Life is longer, the phenomenon that being not susceptible to be broken.

In arm of force component 120, one end of the 2 strip arm of forces 121 is connected on the periphery of inner ring 110, the 2 strip arm of forces 121 The other end be connected.The other end of the 2 strip arm of forces 121 is additionally provided with interconnecting piece 125, can be by the arm of force by interconnecting piece 125 Component 120 is firmly welded on shell 210 or the vibration component 230 of polygon vertical linearity vibrating motor 200.Interconnecting piece 125 length L4 is the one third of L3 to half.The maximum value of the width of interconnecting piece 125 is equal to the thickness of shell 210. Spring 100 during the installation process, on each interconnecting piece 125 setting be provided with 8 welderings evenly and at intervals in inner ring there are one solder joint Point, wherein the sub- arm of force 121 is both provided with solder joint with 110 junction of inner ring.

Width of the sub- arm of force 121 from one end of connection inner ring 110 to the other end：First reduce and increases afterwards.Preferably, the sub- arm of force The width at 121 both ends is more than 2 times of the width at the middle part of the sub- arm of force 121.In this way, stress is smaller everywhere on the sub- arm of force 121, energy The elastic property of the sub- arm of force 121 is enough improved, the vibrating fatigue service life is improved.The width at the both ends of the sub- arm of force 121 is larger to offset Weld the influence to the intensity of spring 100.

Spring 100 is formed by the way of punching molding.One end that the 2 strip arm of forces 121 are connected with each other in arm of force component 120 There are clouts after shaping first cuts away the clout on the sub- arm of force 121, makes 2 strips before spring 100 is mounted in motor The width of one end that the arm of force 121 is connected with each other is less than or equal to the wall thickness of the shell of motor.

There is certain angle between plane where arm of force component 120 and the plane where inner ring 110.The sub- arm of force 121 From one end to the direction of the other end of connection inner ring 110, it is carried out at the same time lateral and vertical extension, the sub- arm of force 121 is vertical On extended distance be spring 100 thickness.The plane mentioned here being transversely parallel to where inner ring 110, it is vertical vertical Plane where inner ring 110.

In arm of force component 120, it is right angle that one end of the 2 strip arm of forces 121, which connect formed angle a with the center of inner ring 110,. In this way, the length of its vertical line of symmetry of arm of force component 120 is larger, the maximum distance between the point on 2 sub- arm of forces 121 in other words Larger, the effective length per the strip arm of force 121 is longer, the elasticity of spring 100 preferably, stroke it is larger, moreover, the 4 strip arm of forces 121 Opposite inner ring 110 is evenly distributed, and more stablizes in vibration processes.

Preferably, in arm of force component 120, the maximum distance between point on the 2 strip arm of forces 121 is more than inner ring 110 most Long length.In this way, being further ensured that the effective length of the sub- arm of force 121 of arm of force component 120 is longer, the elasticity of spring 100 is improved Performance increases stroke.

It please refers to Fig.1 and Fig. 2, distance of the sub- arm of force 121 from one end of connection inner ring 110 to other end relative symmetry line For：The first value L1 is gradually first increased to, then is gradually decrease to second value L2, then gradually increases to third value L3, is finally gradually subtracted As low as zero.

Second value L2 is greater than or equal to maximum value of the point apart from line of symmetry in inner ring 110.In this way, it is ensured that arm of force group The length of its vertical line of symmetry of part 120 is more than the length of 110 vertical symmetrical line of inner ring.

There are many selection, such as circular ring shape, square or other polygons, corresponding, inner ring 110 for the shape of inner ring 110 Middle part open up circular through hole, square through hole or other polygonal through hole.In the present embodiment, inner ring 110 is circular ring shape, second value L2 is greater than or equal to the outer diameter of inner ring 110, and the inner ring 110 of circular ring shape can firmly be welded on polygon vertical linearity vibration horse Up on 200 shell 210 or vibration component 230, uniform force is unlikely to deform, falls off.In other embodiments, inner ring 110 can Corresponding to be square, second value L2 is greater than or equal to the half of the length of side of inner ring 110.

Specifically, on the sub- arm of force 121 from connection inner ring 110 one end to the other end be disposed with the first bending section 122, Second bending section 123 and third bending section 124, the opening direction of the first bending section 122, the opening direction of third bending section 124 Towards line of symmetry, the opening direction of the second bending section 123 deviates from line of symmetry.

The part of one end of the sub- arm of force 121 to the first bending section 122 moves closer to another arm of force component 120, so that sub The arm of force 121 fills the space of 110 surrounding of inner ring as much as possible.

Ranging from 30 °~60 ° of the opening angle b of first bending section 122, the model of the opening angle c of the second bending section 123 Enclose is 120 °~160 °, ranging from 80 °~100 ° of the opening angle d of third bending section 124.In this way, the sub- arm of force 121 is effective Length is as long as possible, and internal stress is as small as possible.The opening angle of bending section refers to the bending section both ends respectively formed by tangent line Angle, the angle that the opening of bending section is unfolded in other words.

Each junction rounding off as possible on spring 100 improves the vibrating fatigue longevity to reduce the internal stress of spring 100 Life is longer.
