Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
Embodiment 1
As shown in Figure 1, 2, a kind of base for voice coil motor, it comprises base body 11 and is arranged at least one compressible PIN 12 in base body 11; Described compressible PIN 12 embeds described base body 11 preferably by its placing mould technique, also can adopt other process Installation in described base body 11.The contact pin one 22 that described compressible PIN 12 comprises a guide cylinder 121 and is set in this guide cylinder 121, the relatively described guide cylinder 121 of this contact pin one 22 moves up and down, and being connected, removing welding process from for being pressed on pcb board with PCB; And because PIN 12 can be compressed voluntarily, also eliminate PIN 12 oversize time subtract the trouble of PIN 12.
Make further improvements, described base preferably but be not defined as square structure, a light hole 111 is provided with in the middle of it, four angles are respectively arranged with fixing hole, the edge of light hole 111 is provided with the first protruding dust ring 112, the arranged outside of the first dust ring 112 has between the second protruding dust ring 113, first dust ring 112 and the second dust ring 113 and forms an annular groove 114.The design of two dust rings increases dust or foreign object enters the path of camera by voice coil motor; dust-proof effect is more excellent; base to the location of carrier and anti-tilt capability stronger; solve in prior art; be arranged on the dust ring on the light hole 111 of motor base; dirt exclusion capabilities is slightly better than the motor not having dust ring, but effect unconspicuous problem.
Embodiment 2
As shown in Figure 3,4, a kind of voice coil motor, comprising: the base 1 of securing part, and this base 1 adopts the base 1 described in embodiment 1, its at least one compressible PIN 12 had for being electrically connected with PCB, to import electric current; The carrier 2 of carrying camera lens, this carrier 2 is arranged on base 1, and is provided with the hollow structure corresponding with the light hole 111 on base 1 in carrier 2; Produce the coil 3 of moment, this coil 3 is arranged on the outside of carrier 2, and described electric current imports through PIN 12 and is energized to coil 3; Produce the magnetite 4 in eternal magnetic field, this magnetite 4 is arranged on the outside of coil 3.The inwall of carrier 2 is circular, and for holding camera lens, outer wall is octagon or other shape; Better base 1 is adapted in order to make carrier 2, support portion, carrier 2 lower end is provided with an annular protrusion 21, the annular protrusion 21 of carrier 2 lower end is clipped in the annular groove 114 that the first dust ring 112 on base 1 and the second dust ring 113 formed, further lengthening motor enters dirt path, reduce camera enter dirt risk, can also make the location of base 1 pair of carrier 2 and anti-tilt capability stronger.Coil 3 is octagon or other shape according to carrier 2 outer wall profile design.Magnetite 4 has four pieces, lays respectively at the outside of coil 3, and corresponding with base 1 four angles.In order to the moment that balance coil 3 is better operationally produced, can be provided with lower shell fragment 6 between coil 3 and base 1, it is electrically connected with PIN 12 and coil 3 respectively, imports electric current be energized through lower shell fragment 6 pairs of coils 3 to realize PIN 12; And shell fragment 5 is provided with on coil 3.Outside magnetite 4 and carrier 2 top is provided with the yoke 8 of integration, for the magnetic line of force that concentrated magnetite 4 produces, and plays protection fixation to the parts of voice coil motor.In order to fix upper shell fragment 5 better, shell fragment lid 7 can be provided with on upper shell fragment 5.When voice coil motor works, the obstructed electric current of upper shell fragment 5, lower shell fragment 6 electric current imports through PIN 12, the eternal magnetic field interaction of magnetic field and magnetite 4 is produced after energising in coil 3, thus coil 3 moves up and down with mobile carrier 2 and camera lens wherein, changed the size of interaction force by the size of current changed in coil 3, wherein descend shell fragment 6 and upper shell fragment 5 to obey Hooke's law.
During specific implementation, adopt the voice coil motor with the base 1 of compressible PIN 12, when assembling, PIN 12 directly can be pressed on pcb board and be connected with PCB, remove welding process from; And because PIN 12 can be compressed voluntarily, also eliminate PIN 12 oversize time subtract the trouble of PIN 12.Generally, dust invades motor internal from the gap between yoke 8 and carrier 2, and then invade camera by the gap between base 1 and carrier 2.The voice coil motor being provided with twice dust ring base 1 can increase the path that dust invades camera, plays better dust-proof effect.When dust invades camera from the gap between base 1 and carrier 2, first can suffer the stop of the second dust ring 113, the dust of part can be blocked; When entering into the annular groove 114 between the first dust ring 112 and the second dust ring 113 again, the stop of the annular protrusion 21 of carrier 2 lower end can be suffered, and enter the turnover that dirt path can produce 90 °; Finally stopped by the first dust ring 112 again by the dust of annular groove 114 on a small quantity, and enter the turnover that dirt path produces 90 ° again.
The above embodiment only have expressed execution mode of the present utility model; it describes comparatively concrete and detailed; but therefore can not be interpreted as the restriction to the utility model the scope of the claims; in every case the technical scheme adopting the form of equivalent replacement or equivalent transformation to obtain, all should drop within protection range of the present utility model.
