Lower direction offers a through-hole, the eyeglass for assembling camera；The upper surface bonding connection of the pedestal positions the upper bullet
Second elastic tip of piece；The lower face bonding connection of the pedestal positions the first elastic tip of the lower shrapnel, and the of lower shrapnel
Two elastic tips are then positioned at the top of the pedestal；The periphery of the pedestal is arranged with coil, the coil and is positioned at the yoke
The magnetite in iron is correspondingly arranged；Also, when the coil is not powered on, the upper shrapnel and the lower shrapnel are in water
It is flat planar deformation to may be not present；
The yoke is positioned with pedestal assembly, defines to form an assembly space between the two；The carrier is existed by two shrapnels
It is flexibly positioned in the assembly space on the thickness direction of voice coil motor.
Related content in above-mentioned technical proposal is explained as follows：
1. in said program, by the combination assembling form of the first assembly and this two assembly of the second assembly, can be improved
The efficiency of assembling of voice coil motor and the yields for improving product.
2. in said program, " when the coil is not powered on, the upper shrapnel and the lower shrapnel are in horizontal put down
Deformation may be not present in planar ", therefore shrapnel is without precompression, it, can be upward by the effect of electromagnetic force on the one hand after motor energization
Or move downward, another aspect motor is not necessarily to that the precompression of shrapnel is overcome to do work during exercise, so as to reach rapid focus
Effect.
3. in said program, the contact site of the lower face of the pedestal and the first elastic tip of the lower shrapnel is plane,
There is no the structures that such as boss makes lower shrapnel generation predeformation in this way.
4. in said program, there is a gap between the magnetite and the lower shrapnel.
The operation principle and advantage of the present invention is as follows：
A kind of voice coil motor with new function of the present invention, positioning is assembled by the first assembly and the second assembly in above-below direction
It forms；First assembly includes yoke, magnetite and upper shrapnel；Second assembly includes carrier, coil, lower shrapnel and bottom
Seat；Through-hole, the second elastic tip of the upper shrapnel of pedestal upper surface bonding positioning are equipped in the pedestal of carrier；The bonding of pedestal lower face is fixed
First elastic tip of the lower shrapnel in position, the second elastic tip of lower shrapnel are positioned at pedestal top；Carrier periphery is arranged with coil, coil
It is correspondingly arranged with magnetite；When coil is not powered on, upper shrapnel and lower shrapnel are in that horizontal planar deformation may be not present.
Compared to existing technologies, the present invention is by designing a novel voice coil motor, and shrapnel is without precompression, on the one hand
It after motor energization, can be moved upwardly or downwardly by the effect of electromagnetic force, another aspect motor is not necessarily to overcome bullet during exercise
The precompression of piece does work, so as to achieve the effect that rapid focus.
Therefore, the present invention preferably meets the requirement of user, improves the use feeling of user, and more power saving, prolongs
The stand-by time of equipment is grown.

Specific implementation mode
The invention will be further described with reference to the accompanying drawings and embodiments：
Embodiment：Shown in attached drawing 1~6, a kind of voice coil motor with new function, by the first assembly and the second assembly
Assembling positions in above-below direction；By the combination assembling form of two assemblies, the efficiency of assembling of voice coil motor can be improved simultaneously
Improve the yields of product.
First assembly includes yoke 1, magnetite 2 and upper shrapnel 3；The magnetite 2 is fixedly arranged on described in the circumferential
Inside yoke 1, the first elastic tip of the upper shrapnel 3 is positioned at below the head cover of the yoke 1；
Second assembly includes carrier 4, coil 5, lower shrapnel 6 and pedestal 7；The carrier 4 includes a pedestal 8, pedestal 8
In offer a through-hole 9, the eyeglass for assembling camera along the vertical direction；The upper surface bonding connection positioning of the pedestal 8
Second elastic tip of the upper shrapnel 3；The lower face bonding connection of the pedestal 8 positions the first elastic tip of the lower shrapnel 6,
Second elastic tip of lower shrapnel 6 is then positioned at the top of the pedestal 7；The periphery of the pedestal 8 is arranged with coil 5, the coil 5
It is correspondingly arranged with the magnetite 2 being positioned in the yoke 1；Also, when the coil 5 is not powered on, the upper shrapnel 3 with
And the lower shrapnel 6 be in it is horizontal it is planar may be not present deformation, therefore shrapnel is without precompression, on the one hand in motor energization
Afterwards, it can be moved upwardly or downwardly by the effect of electromagnetic force, another aspect motor is not necessarily to overcome the precompression of shrapnel during exercise
Acting, so as to achieve the effect that rapid focus.
The yoke 1 is positioned with the assembly of the pedestal 7, defines to form an assembly space 10 between the two；The carrier 4 passes through
Two shrapnels are flexibly positioned in the assembly space 10 on the thickness direction of voice coil motor.Also, the magnetite 2 with it is described under
There is a gap a between shrapnel 6.
Wherein, the lower face of the pedestal 8 and the contact site of the first elastic tip of the lower shrapnel 6 are plane, are not present
Such as boss makes the structure of the generation predeformation of lower shrapnel 6 in this way.
Compared to existing technologies, the present invention is by designing a novel voice coil motor, and shrapnel is without precompression, on the one hand
It after motor energization, can be moved upwardly or downwardly by the effect of electromagnetic force, another aspect motor is not necessarily to overcome bullet during exercise
The precompression of piece does work, so as to achieve the effect that rapid focus.Therefore, the present invention preferably meets the requirement of user,
The use feeling of user, and more power saving are improved, the stand-by time of equipment is extended.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all according to the present invention
Equivalent change or modification made by Spirit Essence, should be covered by the protection scope of the present invention.
