Description

Technical Field

[0001] The present invention relates to the technical field of optical anti - shake, and particularly to an image sensor anti - shake motor with a larger stroke range and a smaller volume. Background Art

[0002] In existing camera modules with anti - shake functions, an anti - shake motor is used to drive the lens assembly or / and the image sensor to move, so as to adjust the relative position between the lens assembly and the image sensor, thereby achieving anti - shake. Among them, since the volume of the image sensor is smaller than that of the lens assembly, the space reserved for the method of driving the image sensor to move for anti - shake is relatively small, which can reduce the thickness of the camera module, reduce the volume of the camera module, and reduce the occupied space.

[0003] In existing camera modules that drive the image sensor for anti - shake, the image sensor is generally mounted on a fixed part through an elastic component, and the anti - shake motor is used to drive the image sensor to move. At the same time, the image sensor is electrically connected to the main board through a flexible circuit board, on the one hand, supplying power to the image sensor, and on the other hand, transmitting the image signal to the main board. Therefore, the flexible circuit board will inevitably affect the movement of the image sensor, thereby affecting the anti - shake effect.

[0004] To improve the foregoing defects, the existing method generally folds the flexible circuit board multiple times continuously to reduce the stiffness of the flexible circuit board. For example, the flexible circuit board is folded into an S - shape, a "ji" shape, etc., so as to obtain good deformation ability and reduce the influence of the flexible circuit board on the movement of the image sensor; or the flexible circuit board is folded into a frame shape and surrounded around the image sensor to reduce the occupied space. In existing anti - shake motors, due to the structural settings of the elastic component and the flexible circuit board, there is a problem of large occupied space, which is not conducive to the miniaturization of the overall structure of the anti - shake device; in addition, there is still room for improvement in the movement stroke of the existing image sensor to obtain a larger movement stroke and improve the anti - shake accuracy.

[0005] Therefore, it is necessary to provide an image sensor anti - shake motor with a larger stroke range and a smaller volume to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide an image sensor anti - shake motor with a larger stroke range and a smaller volume.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: An image sensor image stabilization motor is provided, comprising a base plate, an elastic circuit board, a mounting frame, a drive mechanism, and an image sensor; wherein, the elastic circuit board includes a first fixing part, a second fixing part disposed around the first fixing part, and a plurality of elastic arms connected between the two; the first fixing part is mounted on the base plate via a planar bearing, and the second fixing part is fixed to the base plate to pre-deform the elastic arms; the mounting frame is fixed to the second fixing part and located above the elastic circuit board; the image sensor is mounted on the first fixing part and electrically connected thereto, and the image sensor is movably housed within the mounting frame; the drive mechanism includes at least two drive units, each drive unit being mounted on the mounting frame and having a single-point drive structure, driving the image sensor to translate or rotate via each drive unit.

[0008] Preferably, the flexible circuit board includes a metal layer and a circuit layer disposed on the metal layer, the image sensor and the mounting frame are both located above the circuit layer, and the image sensor is electrically connected to the circuit layer.

[0009] Preferably, the mounting frame has a conductive insert embedded therein, one electrical connection end of the conductive insert is exposed in the mounting frame and electrically connected to the circuit layer, and the other electrical connection end of the conductive insert is exposed in the mounting frame and electrically connected to the drive unit.

[0010] Preferably, the elastic arm includes at least a first connecting arm, a second connecting arm, and a bending portion, wherein the first connecting arm and the second connecting arm are connected through the bending portion, and the first connecting arm and the second connecting arm are respectively connected to the first fixing portion and the second fixing portion.

[0011] Preferably, the first fixing part has a first connecting end protruding from its edge, and the second fixing part has a second connecting end protruding from its edge. The first connecting end and the second connecting end are staggered, and the first connecting arm and the second connecting arm are respectively connected to the first connecting end and the second connecting end.

[0012] Preferably, the driving unit has four units, each of which includes a movable end. The movable ends of the four driving units are located at two vertices on the first diagonal of the mounting frame. When the movable ends move, they can drive the image sensor to translate or rotate.

[0013] Preferably, each of the drive units includes a fixed end, and the fixed ends of the four drive units are fixed to the two vertices of the second diagonal of the mounting frame that intersects the first diagonal.

[0014] Preferably, each of the driving units further includes an SMA line, the two ends of which are respectively connected to the fixed end and the movable end. When the SMA line is energized and contracts, it drives the movable end to move so as to act on the image sensor.

[0015] Preferably, each of the drive units further includes a push block connected to the movable end and protruding toward the image sensor, and the push block is insulated from the side of the image sensor. When the SMA line is energized and retracted, the movable end can be moved to allow the push block to push the image sensor.

[0016] Preferably, each of the drive units includes a spring with an elastic structure, one end of which is fixed to the mounting frame, and the other end of which forms the movable end.

[0017] Compared with the prior art, the image sensor image stabilization motor of the present invention, firstly, includes a flexible circuit board comprising a first fixing part spaced apart from each other, a second fixing part surrounding the first fixing part, and a plurality of flexible arms connecting the two. The first fixing part is mounted on the base plate via a planar bearing, and the second fixing part is fixed to the base plate to pre-deform the flexible arms. Therefore, the flexible circuit board not only provides elastic support for the image sensor but also enables electrical connection to the image sensor, reducing the number of components in the image sensor image stabilization motor compared to the prior art, thus simplifying its structure. Furthermore, the flexible circuit board has a planar structure, occupying little space, which is beneficial for image processing. The reduction in the overall size of the sensor stabilization motor further enables device miniaturization. Secondly, the use of planar bearings reduces the elastic stiffness requirements of the elastic arm, lowering design complexity. The pre-deformed installation of the elastic arm prevents the elastic circuit board from tilting or flipping during pulling, thus preventing the image sensor mounted on the first fixed part from tilting or flipping during movement and improving stabilization accuracy. Furthermore, the drive unit is a single-point drive structure, meaning that each drive unit has only one point of contact with the image sensor. When the image sensor is driven to translate or rotate by each drive unit, the stroke range of the image sensor is increased, further improving stabilization accuracy. Attached Figure Description

[0029] First, combine Figures 1-10 As shown, the image sensor image stabilization motor 100 provided by the present invention includes a base plate 110, a planar bearing 120, an elastic circuit board 130, a mounting frame 140, a drive mechanism 150, and an image sensor 160. The elastic circuit board 130 has an elastic structure and a circuit layer. The middle part of the elastic circuit board 130 is mounted to the base plate 110 via the planar bearing 120. The periphery of the elastic circuit board 130 is pressed down and fixed to the base plate 110, thereby causing the elastic circuit board 130 to undergo pre-deformation. (See attached diagram.) Figure 10As shown, this prevents the elastic circuit board 130 from tilting or flipping during pulling. The mounting frame 140 is fixed above the elastic circuit board 130. The image sensor 160 is fixed to the middle of the elastic circuit board 130 and movably housed within the mounting frame 140. The image sensor 160 is also electrically connected to the elastic circuit board 130; that is, the image sensor 160 is elastically supported within the mounting frame 140 and electrically connected via the elastic circuit board 130. The drive mechanism 150 includes at least two drive units mounted on the mounting frame 140. Each drive unit is a single-point drive structure, driving the image sensor 160 to translate or rotate. During movement in either direction, the image sensor 160 deforms, and when the elastic circuit board 130 returns to its original shape, it resets the image sensor 160.

[0030] The following is combined Figures 2-4 , Figure 10 As shown, in this invention, the elastic circuit board 130 includes a first fixing part 131 and a second fixing part 132 arranged at intervals, and a plurality of elastic arms 133 connected between the two. The second fixing part 132 is arranged around the first fixing part 131, and the plurality of elastic arms 133 are connected to the first fixing part 131 and the second fixing part 132 at intervals. During installation, the first fixing part 131 is mounted on the base plate 110 via a plane bearing 120, and the second fixing part 132 is fixed to the base plate 110 after being pressed down. (See figure) Figure 10 As shown, this causes the elastic arm 133 to pre-deform, preventing the elastic circuit board 130 from tilting or flipping during the pulling process, thereby preventing the image sensor 160 mounted on the first fixed part 131 from tilting or flipping during the movement, thus improving the anti-shake accuracy; and through the setting of the plane bearing 120, the elastic arm 133 only needs to be able to twist elastically, without having to overcome rotation in all directions, so that the stiffness of the elastic arm 133 in all directions does not need to be considered in the design process, thus reducing the stiffness design requirements of the elastic arm 133 and reducing the design cost.

[0031] The following is combined Figure 4-5 , Figure 7 , Figure 10As shown, in this invention, the elastic circuit board 130 includes a metal layer 130a and a circuit layer 130b disposed on the metal layer 130a. The metal layer 130a and the circuit layer 130b have the same shape. The metal layer 130a provides elastic support, and the circuit layer 130b provides wiring. The circuit layer 130b also has pins for electrical connection with external circuitry, enabling electrical connection between the image sensor 160 and the external circuitry. Furthermore, after the mounting frame 140 is mounted on top of the elastic circuit board 130, it is fixed to the second fixing part 132, and the conductive insert 170 embedded in the mounting frame 140 is also electrically connected to the circuit layer 130b to provide power to the drive mechanism 150 (see later description). Therefore, this invention, through the arrangement of the elastic circuit board 130, not only achieves electrical connection but also enables multiple degrees of freedom of movement for the image sensor 160. The elastic circuit board 130 is designed entirely within a plane, requiring no folding, resulting in a simple structure and small space occupation.

[0032] Continue reading Figure 4 As shown, in one embodiment of the present invention, each elastic arm 133 includes at least a first connecting arm 1331, a second connecting arm 1332, and a bending portion 1333. The first connecting arm 1331 and the second connecting arm 1332 are connected by the bending portion 1333. The first connecting arm 1331 is connected to the first fixing portion 131, and the second connecting arm 1332 is connected to the second fixing portion 132.

[0033] In this embodiment, both the first connecting arm 1331 and the second connecting arm 1332 are rod-shaped structures, while the bent portion 1333 is arc-shaped. The included angle between the first connecting arm 1331 and the second connecting arm 1332 is approximately 90°. The mutually perpendicular first connecting arm 1331 and the second connecting arm 1332 enable multiple degrees of freedom of movement for the first fixing portion 131, providing the elasticity and deformation required for the movement of the first fixing portion 131. Of course, the first connecting arm 1331 and the second connecting arm 1332 are not limited to the aforementioned shapes; for example, they can also be arc-shaped, wavy, etc.

[0034] Continue to combine Figures 3-5As shown, in this embodiment, the edge of the first fixing part 131 is provided with a first connecting end 1311, and the edge of the second fixing part 132 is provided with a second connecting end 1321. The first connecting ends 1311 and the second connecting ends 1321 are staggered. Specifically, the first connecting ends 1311 have two and protrude along a first direction, that is, the two first connecting ends 1311 protrude in opposite directions, and the second connecting ends 1321 protrude along a second direction, that is, the two second connecting ends 1321 protrude towards each other. A plurality of spaced elastic arms 133 are connected between adjacent first connecting ends 1311 and second connecting ends 1321, and the first connecting arm 1331 of each elastic arm 133 is connected to the first connecting end 1311 and the second connecting arm 1332 is connected to the second connecting end 1321, thereby forming an elastic arm group. The inner and outer sides of each elastic arm group are spaced apart from the first fixing part 131 and the second fixing part 132, respectively. Thus, the elastic circuit board 130 has a total of four elastic arm groups, such as Figure 4 As shown. Understandably, the number of elastic arm assemblies and elastic arms is not limited to that shown in this embodiment, and other forms are also possible.

[0035] The following is combined Figure 4 , Figures 6-7 , Figure 10 As shown, in this invention, the mounting frame 140 is fixed to the second fixing part 132 and located above the elastic circuit board 130. A conductive insert 170 is embedded within the mounting frame 140. The first electrical connection end 171 of the conductive insert 170 protrudes from the bottom of the mounting frame 140 and is electrically connected to the circuit layer 130b. The second electrical connection end 172 of the conductive insert 170 protrudes from the side wall of the mounting frame 140 and is used for electrical connection with the drive unit (described later) to supply power to the drive unit. The arrangement of the conductive insert 170 is conventional in the art and will not be described in detail further.

[0036] The following is combined Figure 1-3 , Figure 6 , Figure 8-9 As shown, in one embodiment of the present invention, the driving mechanism 150 includes four driving units 150a to 150d. These four driving units 150a to 150d are respectively mounted on the four side walls of the mounting frame 140, and each driving unit 150a to 150d is a single-point driving structure, meaning that each driving unit 150a to 150d has only one point of action with the image sensor 160. Furthermore, the points of action of the four driving units 150a to 150d are located at the two apex positions on the first diagonal L1 of the mounting frame 140, driving the image sensor 160 to translate or rotate.

[0037] Understandably, the number of drive units is not limited to four, nor is it limited to the above arrangement. The image sensor 160 can also be driven to translate or rotate through other arrangements.

[0038] The following is combined Figure 6 , Figure 8-9 As shown, in this invention, the four drive units 150a-150d have identical structures and are respectively mounted on the four side walls of the mounting frame 140. Each of the four drive units 150a-150d includes a fixed end 151 and a movable end 152. The movable end 152 of each drive unit 150a-150d is located at two vertices on the first diagonal L1 of the mounting frame 140, and the fixed end 151 of each drive unit 150a-150d is fixed at two vertices on the second diagonal L2 of the mounting frame 140. The first diagonal L1 and the second diagonal L2 intersect, as shown... Figure 6 As shown.

[0039] Continue reading Figure 6 As shown, when the movable ends 152 of the two diagonally opposite drive units at the two vertices of the first diagonal L1 simultaneously act on the image sensor 160, the image sensor 160 will be driven to rotate. Specifically, when the movable ends 152 of drive units 150a and 150c simultaneously act on the image sensor 160, the image sensor 160 will be driven to rotate counterclockwise, and when the movable ends 152 of drive units 150b and 150d simultaneously act on the image sensor 160, the image sensor 160 will be driven to rotate clockwise.

[0040] Continue reading Figure 6 As shown, when the movable end 152 of one of the driving units acts on the image sensor 160, and the movable ends 152 of the other two adjacent driving units simultaneously act on the image sensor 160 with a slightly smaller force to clamp the image sensor 160, the image sensor 160 can be pushed to translate. Specifically, when the driving unit 150a needs to push the image sensor 160 to translate, the driving units 150b and 150d act on the image sensor 160 with a force smaller than that of the driving unit 150a. The driving units 150b and 150d generate opposite forces on the image sensor 160 to clamp the image sensor 160. At this time, when the movable end 152 of the driving unit 150a pushes the image sensor 160, it can be translated.

[0041] The following is combined Figure 8-9As shown, in this invention, each drive unit 150a-150d further includes an SMA line 153. The two ends of the SMA line 153 are connected to a fixed end 151 and a movable end 152, respectively. The SMA line 153 extends along the side wall of the mounting frame 140. The fixed end 151 and the movable end 152 respectively contact the conductive insert 170 embedded in the mounting frame 140, thereby supplying power to the SMA line 153. When the SMA line 153 is energized and retracts, it drives the movable end 152 to move and act on the image sensor 160, while the fixed end 151 remains stationary, thus forming a single-point drive structure. The stroke of the single-point drive method is twice that of the two-point drive method, thus enabling the image sensor 160 to obtain a larger travel distance and improving the image stabilization performance of the image stabilization motor 100.

[0042] Continue to combine Figure 8-9 As shown, in this invention, each drive unit 150a-150d includes at least one elastic spring sheet, which forms the movable end 152. See details... Figure 9 As shown, the spring 152 includes a bent functional part 1521 and a fixing part 1522. The spring 152 is snapped onto the mounting frame 140, and the fixing part 1522 of the spring 152 is fixed to the mounting frame 140 and electrically connected to the conductive insert 170. The functional part 1521 of the spring 152 extends into the mounting frame 140 for interacting with the image sensor 160.

[0043] More preferably, the stiffness of the action portion 1521 of the spring 152 along the Z-axis is greater than its stiffness perpendicular to the Z-axis. When the SMA cable 153 is energized and contracts, it can pull the action portion 1521 of the spring 152 to deform and move. The action portion 1521 acts on the image sensor 160 to push it to move or rotate. The displacement of the image sensor 160 caused by the movement of the action portion 1521 is greater than the amount of contraction of the SMA cable 153, thereby giving the image sensor 160 a larger travel distance and improving the anti-shake performance of the image stabilization motor 100. After the SMA cable 153 is de-energized and relaxed, the action portion 1521 of the spring 152 recovers its deformation and automatically resets, thereby disengaging from the image sensor 160. In addition, it can also prevent the image stabilization motor 100 from being subjected to a large impact force, which could cause the SMA cable 153 to be stretched too much and break.

[0044] Continue to combine Figure 8-9 As shown, in one embodiment, each drive unit 150a-150d includes two spring clips with identical structures. One spring clip is fixed to the mounting frame 140 to form the aforementioned fixed end 151, and the other spring clip forms the aforementioned movable end 152. It is understood that the fixed end 151 is not limited to being fixed by the aforementioned spring clips; other structural arrangements do not affect the function of the drive units 150a-150d.

[0045] See Figure 6-9 As shown, in one embodiment, each of the drive units 150a to 150d further includes two reinforcing plates 154, each reinforcing plate 154 being fixed to a spring sheet, and the reinforcing plate 154 contacting the conductive insert 170 (see...). Figure 6 The SMA line 153 is powered through the reinforcing plate 154 and the spring plate.

[0046] Combination Figure 6-7 As shown, the mounting frame 140 has mounting grooves 141 on its sidewalls, identical to the aforementioned spring clip structure. Specifically, each sidewall of the mounting frame 140 has two mounting grooves 141. Two spring clips are fitted into the mounting grooves 141 and arranged symmetrically. The two ends of the SMA wire 153 are connected to the far ends of the two spring clips. Simultaneously, the aforementioned reinforcing piece 154 is fixed to the near end of each spring clip, and conductivity is achieved through the reinforcing piece 154 contacting the second electrical connection terminal 172 of the conductive insert 170.

[0047] Understandably, the two springs can also be designed as an integral structure, that is, the two springs can be fixedly connected or integrally formed at their close ends or the reinforcing plate 154, which does not affect the realization of the function of the drive unit 150a to 150d.

[0048] Continue reading Figure 6 , Figure 9 As shown, in this invention, each drive unit 150a-150d further includes an insulating block 155, which is formed of insulating material. The insulating block 155 also has a groove formed on it, and a push block 1551 is integrally formed on one side of the insulating block 155. The push block 1551 has an arc-shaped structure. During connection, the insulating block 155 is clamped to the movable end 152, and the push block 1551 is positioned facing the image sensor 160. By pushing the image sensor 160 with the push block 1551, insulation and wear prevention functions can be achieved. Of course, the insulating block 155 is not limited to the aforementioned structure and connection method; for example, the insulating block 155 can also be directly pasted onto the movable end 152.

[0049] Understandably, the insulating block 155 and the push block 1551 are not limited to the aforementioned arrangement. For example, in other embodiments, the push block 1551 can be integrally formed on the movable end 152, protruding towards the image sensor 160, and an insulating layer can be correspondingly provided on the side of the push block 1551 or / and the image sensor 160 to achieve an insulation effect. In addition, the push block 1551 is not limited to being arc-shaped; it can also be set to any other arbitrary shape.

[0050] Let's combine them again below. Figures 1-10 The working principle of the image sensor anti-shake motor 100 of the present invention will be explained as shown.

[0051] Combination Figure 1 , Figure 6 , Figure 8-9 As shown, when the image sensor 160 needs to send... Figure 1 When the Y-axis moves in the positive direction, the SMA line 153 of the drive unit 150a is energized, causing the SMA line 153 to contract, thereby pulling the movable end 152 of the drive unit 150a to deform and move towards the image sensor 160. The push block 1551 on the movable end 152 pushes the image sensor 160 to move it.

[0052] Simultaneously, the SMA lines 153 of drive units 150b and 150d are energized, and the current in both is less than that in drive unit 150a. Therefore, the contraction of the SMA lines 153 in drive units 150b and 150d is less than that in drive unit 150a. The contraction of the SMA lines 153 in drive units 150b and 150d pulls their movable ends 152 towards the image sensor 160. The movable ends 152 act on the two apex corners of the image sensor 160, generating opposing forces that clamp the image sensor 160. Thus, drive unit 150a can push the image sensor 160 to translate. When the image sensor 160 needs to translate in other directions, the principle is the same as described above, and therefore will not be repeated.

[0053] When the image sensor 160 needs to be driven to rotate, for example, when it needs to rotate along... Figure 1 , Figure 6 When rotating clockwise (as indicated by the arrow), the SMA lines 153 of drive units 150b and 150d are energized, causing the SMA lines 153 to contract. This pulls their movable ends 152, deforming them and moving them toward the image sensor 160. The push blocks 1551 on the movable ends 152 push against the two apex corners of the image sensor 160, i.e., generating opposite forces on the image sensor 160 at the two apex corners on the first diagonal L1, thereby pushing the image sensor 160 to rotate clockwise. Correspondingly, when the image sensor 160 needs to rotate counterclockwise, the SMA lines 153 of drive units 150a and 150c are energized.

[0054] During the translation or rotation of the image sensor 160, the elastic arms 133 of the elastic circuit board 130 deform to meet the requirements of translation or rotation, enabling multi-degree-of-freedom movement of the image sensor 160 and achieving good image stabilization. Furthermore, when the elastic arms 133 recover their deformation, they can drive the image sensor 160 to reset. The elastic circuit board 130 has a planar structure, occupies little space, and while providing elastic support for the image sensor 160, it does not affect the movement of the image sensor 160, thereby improving image stabilization accuracy.

[0055] In summary, the image sensor stabilization motor 100 of the present invention, firstly, includes a flexible circuit board 130 comprising a first fixing part 131 spaced apart from each other, a second fixing part 132 surrounding the first fixing part 131, and a plurality of flexible arms 133 connected between the two. The first fixing part 131 is mounted on the base plate 110 via a planar bearing 120, and the second fixing part 132 is fixed to the base plate 110, causing the flexible arms 133 to pre-deform. Therefore, the flexible circuit board 130 not only provides elastic support for the image sensor 160 but also simultaneously provides electrical connection to the image sensor 160, reducing the number of components in the image sensor stabilization motor 100 compared to the prior art, thus simplifying its structure. Furthermore, the flexible circuit board 130 has a planar structure, occupying a small area... The small footprint allows for a reduction in the overall size of the image sensor stabilization motor 100, further miniaturizing the device. Secondly, the planar bearing 120 reduces the elastic stiffness requirement of the elastic arm 133, lowering the design complexity. The pre-deformed installation of the elastic arm 133 prevents the elastic circuit board 130 from tilting or flipping during pulling, thus preventing the image sensor 160 mounted on the first fixed part 131 from tilting or flipping during movement, improving stabilization accuracy. Furthermore, all drive units are single-point drive structures, meaning that each drive unit has only one point of contact with the image sensor 160. When the image sensor 160 is driven to translate or rotate by each drive unit, the stroke range of the image sensor 160 is increased, further improving stabilization accuracy.

[0056] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
