In following description, by describing and, having shown specific embodiments of the invention with reference to accompanying drawing.Will be understood that, under the prerequisite that does not break away from the scope of the invention, can make the change of structure and others it, and as other embodiment.And the various aspects of various embodiment and each different embodiment thereof can be used in combination in any suitable manner.Therefore, accompanying drawing and being described in detail in is counted as descriptive and nonrestrictive in essence.In each accompanying drawing, identical parts are to be represented by identical reference encoder.
The embodiment of the invention is usually directed to a kind of lens control device with automatic focusing and motion control function.According to an embodiment, lens control device comprises an imaging len support, and it is used for carrying an imaging len unit; With a plurality of actuators, these a plurality of actuators are set to be driven into as lens carrier in the imaging len control device and move along preset direction.The imaging len support is according to focusing control signal and motion control signal are made motion automatically.For example, when as camera component, the imaging len support can shift near or move dolly-out,s dolly-back the picture target to adjust focal length.And, can move or swing (pivot) imaging len support and compensate any rocking or other motion of taking place when camera uses.For example, the optical axis of considering the imaging len unit is that the imaging len support can be swung horizontally and vertically to handle two motions on the different directions towards the shooting target.
Referring to figs. 1 through 3, shown a lens control device 100.Fig. 1 is the synoptic diagram of lens control device 100, and Fig. 2 is the side view of lens control device 100 shown in Figure 1, and Fig. 3 is the vertical view of lens control device 100 shown in Figure 1.Lens control device 100 comprises a upper shell 102, lower house 104, an imaging len unit 106 and a bearing 116.Upper shell 102 and lower house 104 couple together and form the housing of lens control device 100.According to an embodiment, the service part of lens control device 100 all is installed in this housing.
According to one embodiment of the invention, Fig. 4 is the side cross-sectional, view of lens control device shown in Figure 1.This sectional view is to cut open from A place, Fig. 3 interior lines.In sectional view, show and described lens control device configuration of components and operation, those parts shown in being included in Fig. 1 to 3.Upper shell 102, lower house 104, imaging len unit 106 and automatic focus actuator magnetic part 108 have been shown. Imaging len unit 106 and 110 engagements of imaging len support.In an embodiment, the outside surface of imaging len unit 106 has screw thread, and imaging lens carrier 110 also has screw thread, the screw thread of its corresponding imaging len unit 106, and by screw-threaded engagement, imaging len unit 106 couples together with imaging len support 110.Coil 112 is attached on the imaging len support 110, and wherein the athletic meeting of coil 112 makes imaging len support 110 produce corresponding motion.A plurality of corner posts (corner post) 114 are arranged on lower house 102, a corner post is respectively arranged on each angle of lower house 102, each corner post 114 engages with a corresponding bearing 116.Each bearing 116 is usually located on the position, angle of imaging len control device 100.One group 4 automatic focus actuator magnetic parts 108 are positioned in the housing, and each all is positioned on each angle of lower house 104.The automatic focus actuator magnetic part 108 that each bearing 116 is all corresponding with one engages.Each automatic focus actuator magnetic part 108 can produce interaction force with respect to coil 112.Coil 112 has constituted an automatic focus actuator 119 with automatic focus actuator magnetic part 108.Thereby, a machine-processed automatic focusing campaign that is used to be controlled to picture lens unit 106 of focusing automatically is provided.
One group of actuator magnetic part can produce interact (shown in Figure 5) with first coil 120 and second coil 124.First magnetic part 118 of actuator magnetic part is placed near first coil 120.First magnetic part 118 and first coil 120 constitute first actuator 121.Second magnetic part 122 (shown in Figure 5) of actuator magnetic part group and second coil 124 (shown in Figure 5) constitute second actuator 125.Thereby, provide a motion control mechanism to be used to be controlled to and made oscillating motion (pivoting motion) along both direction as lens unit.
In an embodiment, first actuator 121 and second actuator 125 all are configured to produce transverse movement.But,, therefore between lower spring 126 and upper spring 128, in fact produced a fulcrum along optical axis because lower spring 126 and upper spring 128 are arranged.But, to implement according to difference, fulcrum can be created on the interior diverse location of control device.The motion of imaging len support 110 for convenience of description, fulcrum should be counted as reference standard usually, rather than a physical unit or another parts are around the position of its swing.The position of imaging len support 110 will correspondingly change during lengthwise movement (focusing motion automatically), and therefore the transverse movement of first transverse actuator 121 and second transverse actuator 125 makes imaging len support 110 about fulcrum generation oscillating motion.Because first transverse actuator 121 and second transverse actuator 125 apply acting force on imaging len support 110, no matter be to apply acting force together or separately, all can produce banking motion, make imaging len support 110 swing about fulcrum.In another embodiment, first transverse actuator 121 and second transverse actuator 125 can be on diverse locations with respect to upper spring and lower spring, to increase the moment arm length apart from fulcrum, this can reduce to need to produce the acting force of banking motion, and avoids unnecessary laterally moving.
Lower spring 126 is positioned at lower house 104, and upper spring 128 is positioned at upper shell 102.Lower spring 126 is installed between lower house 104 and the imaging len support 110, and upper spring 128 is positioned between upper shell 102 and the imaging len support 110.Lower spring 126 and upper spring 128 are assisted to be controlled to picture lens carrier 110 and are moved in housing.For example, lower spring 126 and upper spring 128 can each volute springs (coil spring) naturally, and diameter is bigger than the diameter of imaging len support 110.Lower spring 126 and upper spring 128 also can each flat springs (leaf spring) naturally, and perhaps one or more flat springs are placed the associated end near imaging len support 110.Upper spring also can be positioned on the different positions with lower spring.For example, lower spring 126 and upper spring 128 can be mutually near being placed on the end of imaging len support 110.
According to one embodiment of the invention, Fig. 5 is the exploded view of lens control device shown in Figure 1.Lens control device 100 comprises upper shell 102 and lower house 104, the remaining part of its lens control device of packing into.Imaging len unit 106 is positioned in the housing, and upper shell 102 and lower house 104 all have the opening of setting in last lower house 102,104, to allow moving through opening or to allow to use imaging len unit 106 to carry out image capture.Fig. 5 also shown upper spring 128, lower spring 126, imaging len support 110, comprise coil 112 and automatically focus actuator magnetic part 108 automatic focus actuator, comprise first magnetic part 118 and first coil 120 first transverse actuator, comprise second transverse actuator of second magnetic part 122 and second coil 124.
Though " on " and D score be with reference to lens control device 100 as shown in drawings towards being described, when actual operation, optical axis is to align with the direction that lens control device 100 is taken a picture.For example, if optical axis usually and ground level, first transverse axis should with ground level, and usually perpendicular to optical axis.Second transverse axis is usually perpendicular to optical axis, and with first transverse axis in one plane.
