Description
Technical field
The utility model relates to a kind of mobile phone cam, the voice coil motor mobile phone cam of the guide tracked operation of particularly a kind of lens group.
Background technology
At present, the ultimate principle of voice coil motor is an electromagnetic induction, and coil is subjected to magneticaction and carries out rectilinear motion in magnetic field.Magnetic force that produces behind the coil electricity and magnetite effect promote to carry out rectilinear motion with the carrier of lens group.
In voice coil motor mode automatic focusing mobile phone cam, though the spring leaf that both sides are provided with about carrier can play the effect of certain prop carrier, but because mobile phone is not to work under level conditions all the time, and stability was poor slightly when the magnetic force that magnetite and coil produce promoted carrier, lens group often occurs tilting, the phenomenon of perk, focus on instability, easily cause portrait bad.In order to obtain good portrait effect, must guarantee the stationarity of lens group, avoid, the phenomenon of perk takes place.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point, provides a kind of simple in structure, the voice coil motor mobile phone cam of the guide tracked operation of lens group of dependable performance.
The technical scheme that the utility model adopted is for achieving the above object: the voice coil motor mobile phone cam of the guide tracked operation of a kind of lens group, this mobile phone cam comprise coil and are used for fixing carrier, radome, support and some magnetites of lens group; Described coil is wrapped in the carrier outside, and magnetite is arranged on four limits of support outer symmetrical, and the fixing inside that is placed on radome of magnetite; Magnetic force that produces behind the coil electricity and magnetite effect promote to carry out rectilinear motion with the carrier of lens group, and the upper and lower surface at carrier is provided with the spring leaf that is used for limiting the carrier movement position simultaneously; It is characterized in that described carrier inside and lens group threaded engagement; Carrier is outside to form that 120 ° three limits are equidistant to be arranged with three boss, or equidistantly is provided with three with convex platform, and the boss support coils is circular uniformly at interval twines; In coil perpendicular to equidistant coaxial three slide rails that are symmetrical arranged in three limits that form 120 ° on the plane of lens group optical axis, or equidistant three above slide rails are set, slide rail and radome are connected to form one, and carrier drives lens group and moved up and down according to the direction of lens group optical axis by the spacing cooperation of slide rail.
The beneficial effects of the utility model are: because the voice coil motor mobile phone cam adopts the structure based on the motion of camera lens rail, the carrier of fixed lens group according to orbital motion, reaches desirable portrait effect in the automatic focusing process.This structure has following some advantage:
(1) camera size constancy: though set up three slide rails in it, slide rail all is arranged in the inner space of voice coil motor, can not have influence on the overall dimensions of camera.
(2) manufacture craft is simple: three slide rails and radome integrated design, the technological process of manufacturing during with existing no slide rail is identical, can so not increase technology difficulty.
(3) producing cost is saved: use the voice coil motor of slide rail type can reduce the bad goods that lens group tilts, perk caused to greatest extent, save production cost effectively, improved reliability of products.
Description of drawings
Fig. 1 is the structural representation of existing voice coil motor;
Fig. 2 is that the utility model is based on lens group rail motion voice coil motor structure vertical view;
Fig. 3 is the utility model carrier, coil and slide rail relative position synoptic diagram.
Among the figure: 1 lens group, 2 magnetites, 3 carriers, 4 radomes, 5 coils, 6 supports, 7 slide rails.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, details are as follows to embodiment, structure, feature that foundation the utility model provides:
As shown in Figure 1, existing mobile phone cam comprises coil 5 and carrier 3, radome 4, support 6 and some magnetites 2 of being used for fixing lens group 1.Coil 5 is wrapped in carrier 3 outsides, and magnetite 2 is arranged on four limits of support 6 outer symmetrical, and fixedly the support 6 of magnetite 2 places the inside of radome 4.Magnetic force that coil 5 energising backs produce and magnetite 2 effects promote to carry out rectilinear motion with the carrier 3 of lens group 1, and the upper and lower surface at carrier 3 is provided with the spring leaf that is used for limiting carrier 3 movement positions simultaneously.
As shown in Figure 2, be provided with screw thread in the described carrier 3, carry out threaded engagement with lens group 1; Carrier 3 is outside to form that 120 ° three limits are equidistant to be arranged with three boss, or equidistantly is provided with three with convex platform, and boss support coils 5 circular windings uniformly at interval; Idle loop of coil 5 inner formation, correspondence is provided with slide rail 7 in it.
As shown in Figure 3, in coil 5, be symmetrical arranged three slide rails 7, or equidistant three above slide rails 7 be set perpendicular to three limits that respectively become 120 ° on the plane of lens group 1 optical axis are equidistant; Slide rail 7 and radome 4 are connected to form one, and carrier 3 drives lens group 1 and moved up and down according to the direction of lens group 1 optical axis by slide rail 7 spacing cooperations, to reach the purpose of automatic focusing.
When coil 5 energisings, coil 5 is at the magnetic field force effect lower stress of magnetite 2, and the carrier 3 of fixed lens group 1 moves up and down in slide rail 7 directions, until reaching satisfied portrait.In order to guarantee carrier 3 at slide rail 7 direction proper motions, carrier 3 inside and slide rail 7 should guarantee the smoothness on surface and adopt the little material of friction factor.
Above-mentioned detailed description of the voice coil motor mobile phone cam of the guide tracked operation of lens group being carried out with reference to embodiment; be illustrative rather than determinate; therefore in the variation and the modification that do not break away under the utility model general plotting, should belong within the protection domain of the present utility model.
