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.
A kind of spring 100 is present embodiments provided, which is coach spring.The spring 100 mainly applies to polygon
In vertical linearity vibrating motor 200.Spring 100 includes inner ring 110 and the multiple arm of force components for being connected to 110 periphery of inner ring
120.In the present embodiment, the quantity of arm of force component 120 is 4.4 arm of force components 120 are connected to inner ring 110 evenly and at intervals
Periphery.
Arm of force component 120 is symmetrical structure, the center of the line of symmetry of arm of force component 120 Jing Guo inner ring 110, specifically, power
Arm component 120 includes that one end of 2 121,2 strip arm of forces 121 of the sub- arm of force being symmetrically set is connected to the periphery of inner ring 110
On, the other end of the 2 strip arm of forces 121 is connected.In this way, spring 100 has the 8 strip arm of forces 121,121 quantity of the sub- arm of force is more,
During spring 100 vibrates, the internal stress per the strip arm of force 121 is smaller, and vibrating fatigue lasts a long time, and is not susceptible to fracture
Phenomenon.
In other embodiments, the quantity of arm of force component 120 can also be N number of, and N is the integer more than or equal to 2, sub- power
The quantity of arm 121 is then 2N, and the quantity of the sub- arm of force 121 is at least 4.
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 offer circular through hole, square through hole or other polygonal through hole.In the present embodiment, inner ring 110 is circular ring shape, annulus
The inner ring 110 of shape can be firmly welded on the vibration component 230 of polygon vertical linearity vibrating motor 200, uniform force,
It is unlikely to deform, falls off.
Referring to Fig. 2, the sub- arm of force 121 includes sequentially connected first bending section 122, changeover portion 129 and extended segment 128.
First bending section 122 is connected in inner ring 110, and the extended segment 128 of the 2 strip arm of forces 121 is connected.Extended segment 128 is far from inner ring
110 one end is interconnecting piece 130, and for interconnecting piece 130 for being welded to shell 210, the width of interconnecting piece 130 is the sub- arm of force 121
Middle width the best part.
Changeover portion 129 includes recess portion 123 and the second bending section 127.Wherein, the opening of recess portion 123 deviates from arm of force component 120
Line of symmetry.Recess portion 123 is preferably shaped to U-shaped, in this way, the effective length of recess portion 123 is longer and internal stress is smaller.It is recessed
The direction of the opening in portion 123 then deviates from line of symmetry.
Recess portion 123 includes bottom 124 and is connected to first side 125 and the second side 126 at 124 both ends of bottom, the
Two sides, 126 opposite first center of the side 125 far from inner ring 110.First side 125 is from one end of connection inner ring 110 to another
One end is gradually distance from the center of inner ring 110, and the second side 126 moves closer to inner ring from one end of connection inner ring 110 to the other end
110 center.In other words, the direction of the opening of 2 recess portions 123 on arm of force component 120 is partial to inner ring 110.In this way, energy
Enough effective lengths for increasing the sub- arm of force 121 as much as possible.
Second bending section 127 is arranged between extended segment 128 and recess portion 123, the first bending section 122 and the second bending section
127 opening is towards line of symmetry.Preferably, the opening angle of the first bending section 122 is obtuse angle, and the second bending section 127 is opened
Bicker degree is acute angle.In such manner, it is possible to increase the effective length of the sub- arm of force 121 as much as possible, and the internal stress of the sub- arm of force 121 compared with
It is small.Here opening angle refers to bending section both ends tangent line angulation, the angle that the opening of bending section is unfolded in other words.
Extended segment 128 is connected to second one end of bending section 127 far from recess portion 123, and extended segment 128 is from close to recess portion 123
One end be gradually distance from the center of inner ring 110 to the other end and move closer to line of symmetry until distance be zero.That is, sub
The extended segment 128 of the arm of force 121 and the extended segment 128 of another strip arm of force 121 connect on line of symmetry.Extended segment 128 is from close
One end of recess portion 123 gradually increases to other end width.In this way, the junction wider width of 2 extended segments 128, for it is more
The shell 210 of side shape vertical linearity vibrating motor 200 welds, to improve bonding strength.
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.
The sub- arm of force 121 is from the distance of line of symmetry of one end to the other end relative to force arm component 120 of connection inner ring 110：
First gradually increase, then be gradually reduced, then gradually increases, be finally gradually decrease to zero.The sub- arm of force 121 is from connection inner ring 110
Distance of the one end to the other end with respect to the center of inner ring 110 be：First gradually increase, then be gradually reduced, finally gradually increases to most
Big value.The sub- arm of force 121 can make full use of the space of 110 surrounding of inner ring according to such extension form, make the sub- arm of force 121
Effective length is as maximum as possible, the elasticity of spring 100 preferably, stroke it is larger, the internal stress of spring 100 is smaller, the vibrating fatigue longevity
Life is longer, moreover, will not be interfered with each other between the sub- arm of force 121, abrasion is few, and noise is small, and the service life of spring 100 is more
It is long.
Fig. 3 and Fig. 4 are please referred to, the present embodiment also provides a kind of polygon vertical linearity vibrating motor 200, and polygon is vertical
Linear vibration motor 200 is quadrangle vertical linearity vibrating motor (square shaped vertical linear vibration motor).Polygon vertical linearity
Vibrating motor 200 includes shell 210 and the stator module 220, vibration component 230 and the spring 100 that are arranged in shell 210.
Stator module 220 is fixedly mounted on the inner wall of shell 210, and the arm of force component 120 of spring 100 is welded on shell
On 210 inner wall, inner ring 110 and the vibration component 230 of spring 100 weld, and enable vibration component 230 with respect to 210 He of shell
Stator module 220 vibrates.
The number of edges of polygon vertical linearity vibrating motor 200 is equal with the quantity of arm of force component 120 of spring 100, sub- power
The quantity of arm 121 is 2 times of the number of edges of polygon vertical linearity vibrating motor 200.Spring 100 has foot to vibration component 230
Enough support forces and uniform force, vibration are stablized.
Polygon vertical linearity vibrating motor 200 provided in this embodiment uses above-mentioned spring 100, and the course of work is made an uproar
Sound is small, and vibration is stablized, and service life is longer.
