Embodiment
Reach technological means and the effect that predetermined goal of the invention is taked for further setting forth the present invention, below in conjunction with accompanying drawing and preferred embodiment, flat elastic piece that foundation the present invention is proposed and its embodiment of voice coil motor, structure, feature and the effect thereof that adopts this flat elastic piece, describe in detail as after.
Seeing also shown in Figure 3ly, is the exploded perspective schematic diagram of the voice coil motor of the present invention's first preferred embodiment.This voice coil motor comprises a loam cake 200, a bottom 205, an outside framework 210, a moving part 220 and two flat elastic pieces 230.
Two above-mentioned flat elastic pieces 230 are fixedly set in the two ends of outside framework 210, are used for moving part 220 is defined in the outside framework 210.
Above-mentioned outside framework 210, four jiaos on the one end are respectively equipped with one first Connection Block 211;
Above-mentioned moving part 220, on the one end four jiaos are respectively equipped with one second Connection Block, 221, the first Connection Blocks 211 and second Connection Block 221 can be respectively a protruded stigma or Screw hole structure (not shown).This moving part 220 can be a camera lens, a camera lens support or a magnetic head etc.
Be provided with magnet 215 around this outside framework 210, be fixed with a coil 225 on this moving part 220, when coil 225 is led to the electric current of different directions, the magnetic field that coil 225 produces attracts mutually with the magnetic field of magnet 215 or repels mutually, moves up or down in outside framework 210 and with respect to outside framework 210 thereby drive moving part 220.
Seeing also shown in Figure 4ly, is the structural representation of Fig. 3 middle plateform shell fragment 230.This flat elastic piece 230 comprises a square fixed frame 231 and four elastic arms 232.
Above-mentioned fixed frame 231, itself and this four elastic arms 232 are positioned at same plane substantially.Four jiaos of this fixed frame 231 respectively are provided with one first connecting portion 2311, and this first connecting portion 2311 can be a circular hole, screw or Screw hole structure (not shown).
Above-mentioned elastic arm 232 comprises an elastic arm body 2321 and is positioned at the first volume pars convoluta 2322 and second curled portion 2323 at elastic arm body 2321 two ends.
This elastic arm body 2321 is rectilinear form, and itself and first volume pars convoluta 2322 and second curled portion 2323 are connected smoothly, and the three is formed in one.
This first volume pars convoluta 2322, its bending direction with second curled portion 2323 is opposite;
This each second curled portion 2323 is connected in one second connecting portion 2324, and this second connecting portion 2324 can be a circular hole, screw or Screw hole structure (not shown).
All corresponding one of them first connecting portion 2311 that is wire-wrapped in fixed frame 231 of the first volume pars convoluta 2322 of each elastic arm 232, each first connecting portion 2311 is to be fixed on one of them first Connection Block 211 of outside framework 210, and all corresponding one of them second Connection Block 221 that is fixed in moving part 220 of each second connecting portion 2324, above-mentioned connected mode is to comprise screw and screw to lock mutually or glued joint.
When moving part 220 moved with respect to outside framework 210, second curled portion 2323 of flat elastic piece 230 was also being followed together and is being moved, thereby made elastic arm 232 that elastic deformation take place.At this moment, because second curled portion 2323 of elastic arm 232 is a curved shape, its stress that is connected the place generation with elastic arm body 2321 will be born a part by its crimping portion, and therefore, this flat elastic piece 230 can bear bigger stress, and have preferable flexible.When coil 225 did not have electric current to pass through, the active force that 215 pairs of moving parts of magnet 220 produce disappeared, and this moving part 220 is owing to the elastic force of elastic arm 232 is got back to original position.
Compared to previous prior art, elastic arm 232 two ends of flat elastic piece 230 of the present invention have included a curled portion, be used for being connected with this fixed frame 231 and this moving part 220, this curled portion can share a part because the stress that elastic deformation produced takes place this elastic arm 232, thereby make this elastic arm 232 can bear bigger stress, increased the flexible of this flat elastic piece 230, wherein, the bending direction of first volume pars convoluta 2322 and second curled portion 2323 is opposite or identical all to have similar effects.
In addition, in the above embodiment of the present invention, one of elastic arm 232 two ends of flat elastic piece 230 only need comprise that a curled portion can also implement, curled portion can be arranged at an end of elastic arm body 2321 and with after first connecting portion 2311 of fixed frame 231 is connected, be connected with first Connection Block 211 of outside framework 210 by first connecting portion 2311, or be arranged at the end that in fixed frame 231, extends from elastic arm body 2321 and be connected with second Connection Block 2324.
Seeing also shown in Figure 5ly, is the floor map of second preferred embodiment of flat elastic piece of the present invention.The difference of the flat elastic piece 230 of flat elastic piece second embodiment of the present invention and first embodiment is: the elastic arm body 3321 of this flat elastic piece 330 is the curling bellows-shaped of rule.
Seeing also shown in Figure 6ly, is the floor map of the 3rd preferred embodiment of flat elastic piece of the present invention.The difference of the flat elastic piece 230 of flat elastic piece the 3rd embodiment of the present invention and first embodiment is: the elastic arm body 4321 of this flat elastic piece 430 is the square-wave form of rule.
Seeing also shown in Figure 7ly, is the floor map of the 4th preferred embodiment of flat elastic piece of the present invention.The difference of the flat elastic piece 230 of flat elastic piece the 4th embodiment of the present invention and first embodiment is: the elastic arm body 5321 of this flat elastic piece 530 is irregular bellows-shaped.
The present invention is not limited to above embodiment, and for example, the shape of this fixed frame can also be other shapes such as circle, rectangle; The quantity of this elastic arm also is not limited to 4, can also as long as in design during flat elastic piece, its elastic arm can make moving part 220 produce when mobile with respect to outside framework 210 with first-class for 1, and elastic arm can produce has buffering and the needed elastic force of playback, promptly can implement.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, though the present invention discloses as above with preferred embodiment, yet be not in order to limit the present invention, any those skilled in the art, in not breaking away from the technical solution of the present invention scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be not break away from the technical solution of the present invention content, according to technical spirit of the present invention to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solution of the present invention.
