Description

Optical assembly, camera module and intelligent equipment with camera module

Technical Field

The application relates to an optical assembly, a camera module with the optical assembly and intelligent equipment with the camera module.

Background

The camera module on the existing intelligent equipment basically drives the lens to longitudinally move to realize automatic focusing through the motor mechanism, but the motor carrier drives the lens to longitudinally move to a certain movement stroke, so that a reserved space is required to be reserved for the longitudinal movement of the lens in the intelligent equipment. Taking a smart phone as an example, along with the fact that the smart phone is thinner, the available space which can be reserved for a camera module in the smart phone is smaller and smaller, and a motor carrier needs a magnet driving coil to generate certain thrust to drive a lens to realize longitudinal movement, wherein the magnet occupies a larger volume inside a motor, and the volume of the magnet is difficult to reduce again for the thrust to reach a certain value, so that the motor structure is improved on the premise that the volume of the magnet is not reduced, the volume of the motor is reduced, and the volume of the camera module of the smart phone is further reduced.

The Shape Memory Alloy (SMA) wire can eliminate deformation at a lower temperature after heating and restore the original shape before deformation, so that the SMA wire can replace a motor to drive a lens to move. Compared with the traditional motor, the SMA wire has smaller volume, can effectively reduce the overall size of the module, and is beneficial to the miniaturization development of the module.

Fig. 1A illustrates a perspective view of an optical assembly according to an exemplary embodiment of the present application when SMA wires are provided.

As shown in fig. 1A, an optical assembly according to an exemplary embodiment of the present application includes a lens module 10, a mount 20, and a fixture 30. The SMA wire 40 is also mounted to the optical assembly before the optical assembly is assembled to the smart device.

The lens module 10 includes a lens 11 and a rectangular outer frame 12 surrounding the lens 11. The rectangular outer frame 12 has four sides. In the perspective view shown in fig. 1A, the structural arrangement of both sides of the outer frame 12 can be seen. It should be understood that there are also similar structural arrangements on the other two sides of the outer frame 12, which are not shown in fig. 1A.

The outer frame 12 includes two wire winding portions, i.e., a first wire winding portion 13 and a second wire winding portion 14, on each side, the first wire winding portion 13 and the second wire winding portion 14 of each side being located in a set of diagonal areas 12A of the outer frame 12. The first and second wire winding portions 13 and 14 may be integrally formed on the outer frame 12 of the lens module 10.

The base 20 is disposed below the lens module 10 for supporting the lens module 10. The lens module 10 is disposed substantially centrally on the mount 20. When driven, the lens module 10 is movable along the optical axis of the lens 11 under the support of the mount 20, and on a plane perpendicular to the optical axis. Hereinafter, the driving and the movement under the driving thereof will be described in detail in connection with the structure of the optical assembly of the present application.

The fixing devices 30 are disposed at the other set of diagonal areas 12B of the outer frame 12 of the lens module 10. The fixing device 30 is fixed to the base 20. As shown, the fixing device 30 has fixing surfaces corresponding to each side of the outer frame 12, that is, the fixing device 30 has four fixing surfaces corresponding to four sides of the outer frame 12, respectively. At each diagonal region 12B there are two fixation faces. Although the two fixation surfaces at each diagonal region 12B are shown as being integrally formed in an L-shape, the two fixation surfaces at each diagonal region 12B may alternatively be completely or partially separated.

The fixing device 30 includes a first power supply fixing end 31, a ground wire fixing end 32, and a second power supply fixing end 33 on fixing surfaces respectively corresponding to each side surface of the outer frame 12. The first power fixing portion 311 corresponding to the first winding portion 13 is provided on the first power fixing end 31, and the second power fixing portion 331 corresponding to the second winding portion 14 is provided on the second power fixing end 33. The first ground fixing portion 321 corresponding to the first winding portion 13 and the second ground fixing portion 322 corresponding to the second winding portion 14 are provided on the ground fixing end 32. The fixing device 30 including the first power fixing end 31, the ground wire fixing end 22, and the second power fixing end 33 is fixed to the base 20, and each of the first power fixing end 31, the ground wire fixing end 22, and the second power fixing end 33 has an electrical connection with the base 20. The first power fixing end 31, the ground fixing end 32 and the second power fixing end 33 are spaced apart from each other to form electrical isolation from each other, and the first power fixing end 31 and the second power fixing end 33 are respectively supplied with power. The power and ground fixing portions may be fixing points on the power and ground fixing ends or fixing elements at the fixing points.

It should be understood that although the first ground fixing portion 321 corresponding to the first winding portion 13 and the second ground fixing portion 322 corresponding to the second winding portion 14 are both provided on the same ground fixing end 32 in fig. 1A, they may be provided on different ground fixing ends, respectively.

Fig. 2 is a partial enlarged view of the fixing device 30 in the embodiment shown in fig. 1A, which corresponds to one fixing surface of the fixing device 30. As can be seen from fig. 2, the ground fixed end 32 is located between the first power fixed end 31 and the second power fixed end 33, so that the first ground fixed portion 321 corresponding to the first winding portion 13 and the second ground fixed portion 322 corresponding to the second winding portion 14 are sharably provided on the same ground fixed end 32. The first power fixing end 31, the ground fixing end 32 and the second power fixing end 33 are spaced apart from each other by a certain distance to ensure electrical isolation from each other. As described above, the fixing device 30 may also include two ground fixing ends on which the first ground fixing portion 321 corresponding to the first winding portion 13 and the second ground fixing portion 322 corresponding to the second winding portion 14 are respectively provided. It should be understood that the power and ground terminals may be provided and disposed in other ways than as illustrated.

Fig. 1A and 2 also show SMA wires 40 disposed on the outside of the lens module 10 and the fixture 30. In the illustrated embodiment, each SMA wire 40 has two fixed ends and one movable end. The two fixed ends (at the two ends) of each SMA wire 40 are fixed to a set of power and ground fixing portions, respectively, and one movable end (at the middle portion) is wound around the winding portion corresponding to the set of power and ground fixing portions.

The first winding portion 13, the first power supply fixing portion 311, and the first ground fixing portion 321 are provided such that: the SMA wire 40 having both ends fixed to the first power supply fixing portion 311, the first ground wire fixing portion 321, and the movable end wound around the first winding portion 13 is formed into two substantially parallel wire segments after winding. The first winding portion 13 has positions to be brought into contact with two substantially parallel SMA wire segments, respectively, and is referred to as a first winding position and a second winding position, respectively. That is, the first wire between the first wire winding position on the first wire winding portion 13 and the fixed position on the first power supply fixing portion 311 and the second wire between the second wire winding position on the first wire winding portion 13 and the fixed position on the first ground wire fixing portion 321 are parallel to each other. The second winding portion 14, the second power supply fixing portion 331, and the second ground fixing portion 322 are provided such that: the two line segments formed by the SMA wire 40 with two ends respectively fixed on the second power supply fixing part 331, the second ground wire fixing part 322 and the movable end wound on the second winding part 14 after winding are approximately parallel; that is, the third wire between the third wire winding position on the second wire winding portion 14 and the fixed position on the second power supply fixing portion 331 and the second wire between the fourth wire winding position on the second wire winding portion 14 and the fixed position on the second ground wire fixing portion 322 are parallel to each other. The winding part and the fixing part are further arranged such that the first and second wires parallel to each other cross the third and fourth wires parallel to each other but do not contact each other, thereby fixing and winding the two SMA wires of the two sets of winding part and fixing part to cross each other but do not contact each other.

For example, on each side face of the outer frame 12, the first winding position and the second winding position of the first winding portion 13 are the same or approximately the same distance from the corresponding side face of the outer frame 12. The third and fourth winding positions of the second winding portion 14 are also the same or approximately the same distance from the corresponding side of the outer frame 12. The first and second winding positions of the first winding portion 13 are different from the corresponding side surfaces of the outer frame 12 in distance from the third and fourth winding positions of the second winding portion 14.

For another example, on each fixing surface of the fixing device 30, the fixing position on the first power fixing portion 311 and the fixing position on the first ground fixing portion 321 are separated from the fixing surface by the same or approximately the same distance. The fixed position on the second power supply fixing portion 331 and the fixed position on the second ground wire fixing portion 322 are separated from the fixed surface by the same or approximately the same distance. The fixed position on the first power fixing portion 311 and the fixed position on the first ground fixing portion 321 are separated from the fixed surface by a distance different from the fixed position on the second power fixing portion 331 and the fixed position on the second ground fixing portion 322.

By arranging the winding position and/or the fixing position at different distances from the side surface or the fixing surface, the two SMA wires fixed and wound on the two groups of winding parts and the fixing part are crossed but are not contacted with each other. In the case where two SMA wires fixed and wound on the two sets of the winding portion and the fixing portion are formed to intersect but not contact each other, the lens 11 can be made to move along the optical axis and move on a plane perpendicular to the optical axis in the case where different SMA wires are driven by power supply.

In the embodiment shown in fig. 1A, the first and second winding portions 13 and 14 are disposed perpendicular to the optical axis of the lens 11 and have a winding structure parallel to the optical axis. Alternatively, the winding portion itself may be not perpendicular to the optical axis, but a plane formed by the first wire and the second wire after winding may be parallel to the optical axis, that is, a center of the first winding structure 131 and a center of the second winding structure 141 described later are perpendicular to the optical axis.

It should be understood that although the outer frame 12 is shown as rectangular in the drawings, the outer frame may be any other suitable shape than rectangular, as long as the positions and structures of the wire winding portions and the fixing portions are set so that the SMA wire can be formed to be wound in a quadrangle (preferably, rectangular), four sides of the quadrangle corresponding to sides of the outer frame in four directions, respectively, and thereby the lens module can be moved in a manner described below. For example, the outer frame may be arc-shaped, the outer surface of the arc-shaped is provided with a winder, and the winder can form a quadrangle, preferably a rectangle, with a power supply fixed end and a ground wire fixed end which are arranged on the fixing device; for another example, the fixing device may be an arc, and the power fixing end and the ground fixing end are disposed on the outer surface of the arc, and the shapes and the sizes of the power fixing end and the ground fixing end are correspondingly changed, so that a quadrilateral similar to a rectangle can be formed together with the winder.

In fact, the outer frame of the lens module may have four sides divided by angular ranges, and the winding portion and the corresponding fixing portion on each side may be provided so as to be able to form the above-described quadrangle. Four sides divided by angular range should be understood as four quadrants divided by the center position of the outer frame as a center point (center), the angular range of each quadrant corresponding to one side. For example, for a rectangular outer frame, the four sides thus divided correspond to the four sides of the rectangle; for a circular outer frame, the four sides thus divided correspond to four quarter arcs. That is, the outer frame of the lens module may be of any shape as long as the winding portion provided on each side divided by the angle is fitted with the corresponding fixing portion on the fixing device to form a desired quadrangular structure.

It should also be understood that the mounts in the above embodiments are not required for the optical assemblies of the present application. For example, the bottom of the fixture may extend laterally beyond a support portion in place of the base.

Fig. 3A shows a schematic view of the winding portion in the embodiment shown in fig. 1A. As shown in fig. 3A, the first wire winding portion 13 and the second wire winding portion 14 extend perpendicularly from the side surface of the outer frame 12, thereby being perpendicular to the optical axis of the lens 11. On the first and second winding portions 13 and 14, a first and second winding structure 131 and 141, respectively, are provided in parallel to the optical axis. For example, the first winding structure 131 and the second winding structure 141 are groove structures respectively disposed on the first winding portion 13 and the second winding portion 14 for winding SMA wires. As shown, the first and second wire winding structures 131 and 141 are respectively disposed at different distances from the side surfaces of the outer frame 12, whereby when the fixing portions on the fixing device 30 are disposed at the same distance from the fixing surface, the two SMA wires 40 fixed and wound as described above cross without contact. The first and second winding portions 13 and 14 shown in fig. 3A have substantially the same length, and the first and second winding structures 131 and 141 are formed at different positions from the head or distal end portions of the first and second winding portions 13 and 14, respectively. It should be understood that the structure of the wire winding portions is not limited thereto, and for example, the first wire winding portion 13 and the second wire winding portion 14 having different lengths may be used, and the first wire winding structure 131 and the second wire winding structure 141 may be formed at the same positions from the head or the distal end portions of the first wire winding portion and the second wire winding portion, respectively, as long as the first wire winding structure and the second wire winding structure are formed at different distances from the side surfaces of the outer frame 12, respectively. In different embodiments, the first winding structure 131 and the second winding structure 141 may also be formed at the same distance from the side of the outer frame 12, and the corresponding fixing portions on the fixing device are formed at different distances from the corresponding fixing surfaces.

Fig. 1B shows a perspective view of an optical assembly according to another exemplary embodiment of the present application when SMA wires are provided. The main difference of the embodiment shown in fig. 1B compared to the embodiment shown in fig. 1A is the structure of the winding portion. The first and second winding portions 15 and 16 in fig. 1B have a structure similar to an L shape, and a body having a winding structure is disposed parallel to an optical axis of the lens 11 and has winding structures 151 and 161 perpendicular to the optical axis.

In the above-described embodiment, in order to facilitate installation of the SMA wire, the heights of the power supply fixing end and the corresponding ground wire fixing end may be set to be different from each other, that is, the fixed positions on the first power supply fixing portion and the fixed positions on the first ground wire fixing portion are different from the distance of the corresponding side of the outer frame, and the fixed positions on the second power supply fixing portion and the fixed positions on the second ground wire fixing portion are different from the distance of the corresponding side of the outer frame. At this time, the overall heights of the power supply fixing end and the ground wire fixing end may be different, or the fixing positions on the power supply fixing end and the ground wire fixing end may be set at different heights.

It should be understood that the shape and configuration of the wire wrap portion itself may not be perpendicular or parallel to the optical axis, as long as the wire wrap structure thereon is parallel or perpendicular to the optical axis as described in the above embodiments. Furthermore, the winding structure can be arranged to form an included angle with the optical axis according to actual needs, and the SMA has higher consistency when contracting due to the existence of the included angle.

Fig. 3B shows a schematic view of the winding portion in the embodiment shown in fig. 1B. As shown in fig. 3B, the main bodies of the first and second wire winding portions 15 and 16 are parallel to the optical axis of the lens 11, and the first and second wire winding portions 15 and 16 have a connection structure extending from the main bodies thereof to the side surfaces of the outer frame 12. Alternatively, the first and second wire winding portions 15 and 16 parallel to the optical axis may be connected to the side surfaces of the outer frame 12 by additional connection members. On the side surfaces of the outer frame 12, a first winding structure 151 and a second winding structure 161 perpendicular to the optical axis are provided, respectively. As shown, the first and second wire winding structures 151 and 161 are respectively disposed at different distances from the side surfaces of the outer frame 12, whereby when the fixing portions on the fixing device 30 are disposed at the same distance from the fixing surface, the two SMA wires 40 fixed and wound as described above intersect without contact. In different embodiments, the first and second wire winding structures may also be formed at the same distance from the side of the outer frame 12, while the corresponding fixing portions on the fixing device are formed at different distances from the corresponding fixing surfaces.

The winding structures shown in fig. 3A and 3B are both i-shaped, i.e., a structure having wider ends and a middle having a certain concave distance with respect to the ends. The recess distance constitutes a recess for receiving the SMA wire and limiting undesired movement of the SMA wire during actuation. Alternatively, a T-shaped winding structure may be used to prevent the SMA wire from falling off during driving. Furthermore, a mushroom head-like structure can be added on the winding structure for limiting the position of the SMA wire and preventing the SMA wire from falling off the winder, and the structure can be similar to screwing a screw into a screw hole or inserting a locating pin into a locating hole. An annular gap exists between the last screw hole and the screw, and the annular gap is used for installing the SMA wire. Because the head of the screw is bigger, the limiting effect on the SMA wire is enhanced.

Fig. 4A and 4B illustrate two winding shapes according to an exemplary embodiment of the present application. Specifically, fig. 4A shows a schematic of the SMA wire 40 wound in a U-shaped configuration, and fig. 4B shows a schematic of the SMA wire wound in an O/α -shaped configuration.

In the illustrated embodiment, each SMA wire is formed into a double-layered wire structure of a U-shape or an O/a-shape after winding, which has better structural strength, higher stability, smaller posture difference, higher focusing accuracy, and the like, than the existing single-wire structure. The structural strength of the SMA wire is enhanced through the double-layer wire structure, and the SMA wire can also bear heavier lenses, such as glass lenses, or lenses with more lenses compared with the existing lenses, so that the quality of the whole module is further improved.

Fig. 5 illustrates a top view of an optical assembly when SMA wires are provided according to an exemplary embodiment of the application. Next, the movement of the optical assembly according to the present application in various directions by the SMA wire will be described with reference to fig. 5.

As shown in fig. 5, the optical assembly according to the present application provides SMA wires on each side. Although not shown in fig. 5, it will be appreciated from the above description that there are two SMA wires on each side that intersect each other but do not contact each other, rather than just one SMA wire. Fig. 5 shows the winding portions 13, 14 provided in the diagonal region 12A of the outer frame 12, and the fixing device 30 provided in the diagonal region 12B. Although fig. 5 shows the wire wrapping portion parallel to the optical axis, it should be understood that the wire wrapping portion may also be perpendicular to the optical axis. For convenience of description, four sides of the outer frame of the optical assembly are respectively numbered as a first side 1, a second side 2, a third side 3, and a fourth side 4 counterclockwise as shown in fig. 5. Meanwhile, as shown in fig. 5, a plane perpendicular to the optical axis is expressed in a rectangular coordinate system, and x and y axes are shown in fig. 5. Based on the coordinate system shown in fig. 5, a direction perpendicular to the xy plane can be regarded as the z-axis, an upward direction perpendicular to the plane is the z+ direction, and a downward direction perpendicular to the plane is the z-direction.

As shown in fig. 5, four sides are divided into two groups, and two opposite sides are one group. Specifically, the first side 1 and the third side 3 are a set for controlling the movement of the lens 11 in the x-direction. The second side 2 and the fourth side 4 are a set for controlling the movement of the lens 11 in the y-direction.

As described above, in the image capturing module of the present application, the fixing device 30 is fixed to the base 20, and therefore, the fixing device 30 and the fixing portion thereon maintain the position unchanged during the movement of the lens 11. When the lens needs to be driven to move in the x+ direction, current is applied to the two SMA wires of the third side face, and the SMA wires of the third side face rise to a preset amount of temperature after being electrified, so that the preset amount of length is contracted. Because both ends of the SMA wire are fixed to the fixing device 30, the positions of both ends of the SMA wire are kept unchanged. When the two SMA wires shrink in length, the movable ends wound around the winding portions apply a force in the x+ direction to the winding portions in common, and the lens 11 is moved a predetermined distance in the x+ direction. Under the condition that the SMA wire of the third side face applies force in the x+ direction and drives the lens to move in the x+ direction, the SMA wire of the first side face is stretched along with the movement of the lens module in the x+ direction. And after the lens module reaches the expected position and keeps a stable state, cooling the SMA wire on the third side surface, so that the lens module is stably kept at the expected position and a corresponding focusing or zooming function is realized.

Similarly, when the lens module needs to be driven to move in the x-direction, current is applied to the SMA wire of the first side surface, so that the SMA wire of the first side surface contracts to drive the lens to move in the x-direction. At this time, the SMA wire of the third side is stretched as the lens module moves in the x-direction.

When the lens needs to be driven to move in the y+ direction, current is applied to the two SMA wires on the fourth side face, and the SMA wires on the fourth side face rise to a preset amount of temperature after being electrified, so that the preset amount of length is contracted. Because both ends of the SMA wire are fixed to the fixing device 30, the positions of both ends of the SMA wire are kept unchanged. When the two SMA wires shrink in length, the movable ends wound around the winding portions apply a force in the y+ direction to the winding portions in common, and the lens 11 is moved a predetermined distance in the y+ direction. Under the condition that the SMA wire of the fourth side face applies force in the y+ direction and drives the lens to move in the y+ direction, the SMA wire of the second side face is stretched along with the movement of the lens module in the y+ direction. And after the lens module reaches the expected position and keeps a stable state, cooling the SMA wire on the fourth side surface, so that the lens module is stably kept at the expected position and a corresponding focusing or zooming function is realized.

Similarly, when the lens module needs to be driven to move in the y-direction, current is applied to the SMA wire of the second side surface, so that the SMA wire of the second side surface contracts to drive the lens to move in the y-direction. At this time, the SMA wire of the fourth side is stretched as the lens module moves in the y-direction.

It should be appreciated that although not shown in fig. 5, the edge of the lens module supported on the base is spaced from the fixture by an appropriate distance so that the lens module can be moved in the x and y directions by the SMA wires by an appropriate distance to achieve an optical anti-shake function.

In order to maintain the axial position of the lens module on the optical axis unchanged when moving in the x-direction and the y-direction, the two SMA wires of each side surface may be arranged to be substantially symmetrical with respect to the crossing position of the two, so that when substantially the same current is applied, the forces applied to the winding portions are also substantially the same, whereby the axial components of the forces applied by the two are substantially cancelled.

The above describes that the wire winding portion and the fixing portion are arranged such that the two SMA wires of each side face intersect but do not contact. That is, one of the two SMA wires of each side is disposed corresponding to the upper fixing portion and the lower winding portion, and the other is disposed corresponding to the lower fixing portion and the upper winding portion, thereby forming a crossing relationship of the two SMA wires.

When the lens needs to be driven to move in the z+ direction, current is applied to one of the two SMA wires on each side, wherein the one SMA wire is located above the fixing part. That is, the SMA wire on the four fixing portions in total is applied with current, and the SMA wire energized is warmed up and thereby contracted by a predetermined amount in length. When the four SMA wires shrink in length, the movable ends wound around the winding portions apply a force in the z+ direction to the winding portions in common, and the lens 11 is moved a predetermined distance in the z+ direction. And after the lens module reaches the expected position and keeps a stable state, cooling the SMA wire on the fourth side surface, so that the lens module is stably kept at the expected position and a corresponding focusing or zooming function is realized.

Similarly, when the lens module needs to be driven to move in the z-direction, current is applied to one of the two SMA wires on each side, wherein the fixed part of the one SMA wire is lower than the fixed part of the other SMA wire, so that the electrified SMA wires shrink to jointly drive the lens to move in the z-direction. Thus, the automatic focusing function of the lens can be realized.

In order to maintain the lens module at a constant position in the x-direction and the y-direction when moving in the z-direction, SMA wires of adjacent sides may be arranged to be substantially symmetrical with respect to the boundary line of the adjacent sides, so that components of forces applied to the winding portion in the x-direction and the y-direction are substantially cancelled out when substantially the same current is applied.

Fig. 6A illustrates a perspective view of a camera module according to yet another exemplary embodiment of the present application when SMA wires are provided. The difference from the embodiment shown in fig. 1A is that a movable end fixing portion is provided on the outer frame 12 of the lens module 10 instead of the winding portion. As shown in fig. 6A, on the outer frame of the lens module 10, a first movable end fixing portion 17 and a second movable end fixing portion 18 are provided to clamp and fix the U-shaped structure of the SMA wire, thereby avoiding friction between the SMA wire and the winder when the lens moves.

FIG. 6B shows a close-up view of the movable end mount in the embodiment shown in FIG. 6A; fig. 6C shows a schematic view of the internal structure of the movable end mount in the embodiment shown in fig. 6A.

In the case of using the movable end fixing portion instead of the winding portion, each of two parallel SMA wire segments corresponding to the U-shaped winding structure is fixed to the movable end fixing portion at least one point in the vicinity of the winding structure. In this case, the first winding position and the second winding position of the winding portion described above may be the first fixing position and the second fixing position of the movable end fixing portion.

At this time, since deformation occurring when the SMA wire fixed inside by the movable end fixing portion is energized does not directly or positively affect the movement of the lens, the SMA wire may alternatively be a split structure at the U-shaped structure, that is, a portion of the SMA wire fixed inside by the movable end fixing portion may be removed. In fact, such a structure corresponds to the embodiment of fig. 1A to 4 in which one SMA wire is provided as two SMA wires, each of which has one end connected to the movable end fixing portion and the other end connected to the power supply fixing portion and the ground fixing portion, respectively, corresponding to the movable end fixing portion.

Under the condition, the two SMA wires are connected between the two end parts of the movable end fixing part and can be electrically connected by the common conductive element, and as the resistance of the common conductive element is smaller than that of the SMA wires, the voltage separated by the SMA wires fixed at the movable end fixing part can be reduced, the electric energy loss is reduced, and the electric energy utilization rate is improved by realizing the electrical connection by the common conductive element.

In this embodiment, the first SMA wire and the second SMA wire are two wires, and two ends of the first SMA wire are fixed at the movable end and the fixed end respectively, and the second SMA wire is also the same.

In one embodiment, two SMA wires may be installed simultaneously and a slightly larger length reserved. The needed line length can be cut out according to actual needs at the movable end fixing part. The position inside the fixed part of the movable end and the SMA wire contact can be a metal structure capable of conducting electricity, so that the wire clamped inside the fixed part of the movable end can be directly short-circuited, and current directly flows from the fixed part of the movable end, thereby realizing the electric connection between the two SMA wires, forming a loop and enabling the SMA wires to work normally.

In the solution shown in fig. 6A, in which the U-shaped structure is fixed by the movable end fixing portion, the two SMA wires fixed to the same movable end fixing portion may be separated from each other by a distance of only about one wire diameter, so that the two SMA wires can move in synchronization better. Alternatively, two SMA wires fixed to the same movable end fixing portion may be spaced a greater distance from each other so as not to contact each other, avoiding friction therebetween.

As shown in fig. 6A, the two movable-end fixing portions of the same side face have different sizes, so that the distance separating the movable-end fixing position on one movable-end fixing portion from the side face is different from the distance separating the movable-end fixing position on the other movable-end fixing portion from the side face.

Fig. 7 illustrates a perspective view of a camera module according to still another exemplary embodiment of the present application when SMA wires are provided. Similar to the embodiment shown in fig. 6A, the movable end fixing portion is also employed in the embodiment of fig. 7 instead of the winding portion. Unlike the embodiment of fig. 6A, in the embodiment of fig. 7, similar fastening components are also employed on the fastening device 30. As shown in fig. 7, the fixing device 30 no longer includes a power fixing end and a ground fixing end electrically isolated from each other, but a first fixing member 34 and a second fixing member 35 are provided on the fixing device. The first power supply fixing portion 311 and the first ground fixing portion 312 are fixed in the first fixing member 34 electrically insulated from each other. The second power supply fixing portion 331 and the second ground wire fixing portion 322 are fixed in the second fixing member 35 electrically insulated from each other. That is, the two ends of each SMA wire whose movable end is fixed to the movable end fixing portion are fixed by the same insulating fixing member, and the distance between the two ends of the wire fixed by the fixing member may be equal to or greater than the diameter of the wire, and the two ends of the SMA wire are led out respectively and electrically connected to the circuit board, instead of directly electrically connected to the circuit board through the fixed end. The SMA wire and the fixing device can be fixed to the fixing device through glue adhesion, the conductive element is arranged in the fixing device, the electrical connection between the SMA wire and the circuit board is realized through the conductive element, and the electrical connection between the SMA wire and the circuit board can be realized through other modes.

In the embodiment shown in fig. 7, the two SMA wires that intersect have equal or approximately equal lengths to avoid mutual friction of the SMA wires when the lens is in motion. When the fixed end is directly electrically connected with the circuit board through the SMA wire, the route of the SMA wire extending downwards above the fixed end is not limited to the one shown in the figure.

Alternatively, the two SMA wires that intersect may also have different lengths. As shown in fig. 8, the two SMA wires that intersect may also have different lengths. In this case, the SMA wire led out through the fixing member on the fixing device may extend directly downward and be electrically connected to the circuit board.

In the embodiments shown in fig. 7 and 8, the SMA wire led out through the fixing piece on the fixing device is connected with the circuit board, and because the SMA wire has the characteristic of thermal shrinkage, a certain length needs to be reserved when the SMA wire is installed, so as to prevent the wire from being broken. Alternatively, the SMA wires may also terminate in a mount and make electrical connection by conventional wire or insert molding.

FIG. 9A illustrates a perspective view of a camera module when SMA wires are provided according to yet another exemplary embodiment of the present application; and fig. 9B shows a side view on one side according to the embodiment shown in fig. 9A.

The embodiment shown in fig. 9A and 9B differs from the embodiment shown in fig. 1A in that the first and second wire winding portions are formed of two parts on the same shaft member 19 parallel to the optical axis, and the shaft members forming the first and second wire winding portions are provided in the support pieces 191 extending outward from the corresponding sides of the outer frame. When the first and second wire winding portions are formed in this way, the shaft member 19 and the support 191 can be integrally formed with the lens and the outer frame 12 of the camera module by an injection molding process, thereby simplifying the manufacturing process.

It should be understood that the winding portion and the movable end fixing portion in the above embodiments may be implemented as other supporting members, as long as the supporting function can be provided to the movable end of the SMA wire, and the lens module is driven to move along with the contraction of the SMA wire in the case that the SMA wire exerts a force due to the contraction.

In the case of using a support portion that has a supporting effect on the movable end of the SMA and is movable by the SMA when the SMA wire contracts, the support position corresponds to the winding position in the above-described embodiment. Thus, in some embodiments, the first line between the first support position on the first support portion and the fixing position on the first power supply fixing portion and the second line between the second support position on the first support portion and the fixing position on the first ground wire fixing portion are parallel to each other, and the third line between the third support position on the second support portion and the fixing position on the second power supply fixing portion and the fourth line between the fourth support position on the second support portion and the fixing position on the second ground wire fixing portion are parallel to each other, and the first line and the second line parallel to each other intersect the third line and the fourth line parallel to each other but do not contact each other. In some embodiments, the first and second support locations are spaced apart from the corresponding side of the outer frame by a different distance than the third and fourth support locations are spaced apart from the corresponding side of the outer frame on each side of the outer frame.

Fig. 10 schematically illustrates a perspective view of an optical assembly according to an embodiment of the present application when SMA wire is wound. Specifically, fig. 10 shows that two SMA wires 40 are provided on four sides of the outer frame 12, respectively, each SMA wire having a fixed end fixed to the fixing device 30 and a movable end supported on the supporting portions 13, 14.

According to the structure described above and shown in the drawings, the present application also provides camera module embodiments with SMA wires.

According to one embodiment, the camera module may include: the lens module is provided with an outer frame, a base which is arranged below the lens module and is used for supporting the lens module, and an SMA wire which is arranged around the outer frame of the lens module in a quadrilateral mode, wherein four sides of the quadrilateral correspond to the sides of the outer frame in four directions respectively, and on each side of the outer frame, the SMA wire comprises a first SMA wire and a second SMA wire, and the first SMA wire and the second SMA wire are arranged to cross each other but are not in contact. In this embodiment, the structure and the position of the fixing device and the supporting portion (including the winding portion and the movable end fixing portion) in the above embodiment may not be particularly limited, as long as the SMA disposed on the side of the outer frame of the lens module is disposed in a quadrilateral shape around the outer frame of the lens module, and the two SMA wires on each side of the quadrilateral can intersect each other but do not contact each other, so that the lens can be driven to move in a desired direction under different driving forces, so that the object of the present application can be achieved.

In one embodiment, the quadrangle is rectangular.

In one embodiment, the first SMA wire and the second SMA wire each have a fixed end and a movable end on each side of the outer frame, the fixed ends being disposed at positions corresponding to one end of each side of the outer frame, the movable ends being supported at the other end of each side of the outer frame, the fixed ends being fixed relative to the base, the movable ends being fixed relative to the outer frame, the movable ends moving the lens module relative to the base upon deformation of the SMA wires. The specific case of what the SMA wires on the outer frame side of the lens module are contracted and moved in different driving modes, respectively, to achieve optical anti-shake and auto-focusing has been described above in detail, and thus a description thereof will not be repeated here. All technical features of the various embodiments described above in connection with the figures are applicable to camera module embodiments with SMA wires without conflict.

For example, in one embodiment, at least one of the first SMA wire and the second SMA wire is folded so as to have two fixed ends and one movable end, the two fixed ends of the at least one of the first SMA wire and the second SMA wire being disposed in a fixed and adjacent position relative to the base. Thereby, the folded two ends SMA wires are formed substantially parallel to each other.

In one embodiment, the movable end of at least one of the first SMA wire and the second SMA wire is supported on an outer frame of the lens module. As described above, the movable end may be supported on the outer frame of the lens module by winding or fixing, and the manner of supporting the movable end on the outer frame is not limited to winding and fixing.

In one embodiment, at least one of the first SMA wire and the second SMA wire is folded into two SMA wire segments, the two SMA wire segments being parallel to each other and having the same length. In different embodiments, the two SMA wire segments may also have different lengths.

In one embodiment, the SMA wires on adjacent sides of the outer frame are symmetrically arranged so that, when substantially the same current is applied to achieve optical anti-shake, the components of the forces applied by the bearings or the support portions on the outer frame in the x-direction and the y-direction substantially cancel. In one embodiment, the first SMA wire and the second SMA wire are arranged symmetrically to each other and have the same length on each side of the outer frame such that, when substantially the same current is applied during focusing, the forces applied to the support or the support on the outer frame are also substantially the same, whereby the axial components of the forces applied by the two are substantially cancelled. In one embodiment, the first SMA wire and the second SMA wire are arranged to have at least a portion that is symmetrical to each other on each side of the outer frame.

In one embodiment, the active ends of the first SMA wire and the second SMA wire are spaced a different distance from each side of the outer frame. In one embodiment, on each side of the outer frame, the fixed ends of the first SMA wire and the second SMA wire are at different distances from each side. Thereby, it is ensured that the two SMA wires of each side face do not rub against each other during movement due to shrinkage, thereby adversely affecting the position of the lens module.

In one embodiment, the lens module has a first support portion and a second support portion on each side of the outer frame, the first support portion and the second support portion supporting the first SMA wire and the second SMA wire, respectively.

In one embodiment, at least a first support portion of the first support portion and the second support portion is a wound portion on which the first SMA wire is wound.

In one embodiment, the winding portion is disposed perpendicular to the optical axis of the lens module and has a winding structure parallel to the optical axis such that the first SMA wire is wound on the winding structure parallel to the optical axis. In one embodiment, the winding portion is disposed parallel to the optical axis of the lens module and has a winding structure perpendicular to the optical axis, such that the first SMA wire is wound on the winding structure perpendicular to the optical axis. In one embodiment, the winding portion has a T-shaped or i-shaped winding structure, and the first SMA wire is wound on the T-shaped or i-shaped winding structure of the winding portion.

In one embodiment, at least a first support portion of the first support portion and the second support portion is a movable end fixing portion, and the first SMA wire is fixed on the movable end fixing portion. In one embodiment, the first SMA wire comprises two separate SMA wire segments, and the interior of the movable end fixing portion further comprises a conductive element disposed between the two separate SMA wire segments. Because the resistivity of the common conductive element is larger than that of the SMA, the SMA wire can divide more voltage, and the electric energy utilization rate is improved. In various embodiments, the first SMA wire may also comprise an entire SMA wire, rather than two separate SMA wires; in this case, no additional conductive element is required in the movable end fixing portion.

It should be understood that the technical features described in any of the above embodiments may be used in whole or in part in other embodiments without conflict. For example, in the embodiment depicted in fig. 1A, one of the wire winding portions may be replaced with a movable end fixed portion, while the other wire winding portion remains with the wire winding portion shown in fig. 1A or other configuration.

The above description is only illustrative of the preferred embodiments of the present application and of the principles of the technology employed. It should be understood by those skilled in the art that the scope of protection referred to in this application is not limited to the specific combination of the above technical features, but also encompasses other technical solutions formed by any combination of the above technical features or their equivalents without departing from the spirit of the application. Such as the above-described features and technical features having similar functions (but not limited to) disclosed in the present application are replaced with each other.
