Abstract
The invention discloses a novel camera drive motor. The novel camera drive motor comprises a magnetic housing, a carrier, at least one elastic element, one or more actuators and a base, wherein the carrier is at least partially arranged in the housing; the elastic element is arranged at one end or two ends of the carrier for providing restoring force to the carrier to control the carrier to move relative to the housing; the actuators can be directly or indirectly arranged on the carrier, and can be electrified to generate linear motion relative to the housing, so that the carrier drives a camera lens to perform linear motion relative to the housing, and a focusing function is realized; the base is in locking connection with the housing. The structure of the drive motor is greatly simplified by the magnetic housing, so that the quantity of forming parts is reduced, the assembly difficulty is reduced, and the production cost is reduced.

Further, described elastic component comprises elastic component and lower elastic component, and described upper elastic component and described lower elastic component are arranged at the two ends of described carrier.
Further, described elastic component is set to flat spring, and comprises multiple conducting element.
Further, also comprise terminal, described terminal is fixedly connected with described base.
Further, described shell is set to metallic alloy shell.
Further, described shell is set to plastic metal mixed injection molding body case.
Further, described shell is set to injection casing.
Beneficial effect of the present invention is: the magnetic shell of tool has greatly simplified the structure of drive motors, decreases the quantity of building block and reduces assembling difficulty, reducing production cost.
Accompanying drawing explanation
With accompanying drawing, the invention will be further described, but the embodiment in accompanying drawing does not form any limitation of the invention.
Fig. 1 is the three-dimensional exploded view of a kind of novel camera drive motors of the present invention;
Fig. 2 is the cutaway view of a kind of novel camera drive motors of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated, and this is preferred embodiment of the present invention.
Embodiment
As shown in Figure 1 and Figure 2, a kind of novel camera drive motors 10 of the present invention, comprising:
The magnetic shell 100 of tool, upper flat spring 130, carrier 12 0, actuator 121, lower flat spring 140, base 110 and terminal 111, wherein, carrier 12 0 is arranged in described shell 100 at least in part, carrier 12 0 can along the axial linear movement of carrier 12 0 in shell 100, described actuator 121 is arranged on described carrier 12 0 directly or indirectly, when actuator 121 is energized, the linear movement of opposite shell 100 can be produced, thus carrier 12 0 can be made to drive camera lens to do the linear movement of opposite shell 100, realize focus function thus, in the present embodiment, actuator 121 is coil 121, upper flat spring 130 and lower flat spring 140 are arranged at the two ends of described carrier 12 0, upper flat spring 130 and lower flat spring 140 provide restoring force or support force for carrier 12 0, to control the movement of carrier 12 0 relative to shell 100, described shell 100 fastens with described base 110, specifically, shell 100 has magnetic, shell 100 is stator, coil 121 is mover, after coil 121 is energized, coil 121 is by the axial motion of Loulun magnetism zone of action mobile carrier 120 along carrier 12 0, it should be understood that, shell 100 instead of traditional magnetite assembly, drive motors 10 in the present embodiment achieves the function of stator without the need to magnetite assembly, simplify the internal structure of drive motors 10, decrease assembly.
Particularly, as shown in Figure 2, the inwall top of shell 100 is connected to flat spring 130, is fastened and is directly fixed with carrier 12 0 by upper flat spring 130, thus decrease this assembly of pad, simplify the structure of drive motors 10 further by shell 100 and base 110.
Described shell 100 is set to magnetisable material shell 100, as metal alloy, and for example plastic metal mixed injection molding body, or plastic cement magnet, as alnico alloy, specifically, metallic alloy shell 100 becomes permanent magnet by adding magnetic, add magnetism method to comprise direct current and add magnetic or pulse adds magnetic, the magnetic shell 100 of tool provides stationary magnetic field for the coil 121 in drive motors 10, drives carrier 12 0 to move with this.
It is worth mentioning that, as shown in Figure 1 and Figure 2, terminal 111 is fixed on bottom base 110 or is plugged on bottom base 110, certainly, terminal 111 also can with base 110 integrated injection molding, lower flat spring 140 has multiple conducting element, terminal 111 and external power source are electrically connected, terminal 111 is also electrically connected with coil 121, lower flat spring 140, and external power source makes coil 121 and lower flat spring 140 be energized by terminal 111, thus forms electric loop.
Finally should be noted that; above embodiment is only in order to illustrate technical scheme of the present invention; but not limiting the scope of the invention; although done to explain to the present invention with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to technical scheme of the present invention or equivalent replacement, and not depart from essence and the scope of technical solution of the present invention.
