[0010] background

[0011] Multi-aperture digital cameras (or multi-cameras) are standard in today's mobile handheld electronic devices (referred to as "mobile devices", such as smartphones, tablets, etc.). Multi-cameras typically include a wide-angle (or "main") camera, an ultra-wide-angle camera, and a telephoto camera.

[0012] In pursuit of higher image quality (IQ), larger and larger image sensors (in wide-angle cameras) and larger and larger zoom factors (in telephoto cameras) are required. Pop-up cameras (“POCs”) combine the advantages of large image sensors or large zoom factors with the slim thickness of mobile devices (including POCs). Pop-up cameras are described, for example, in the co-owned international patent application PCT / IB2020 / 058697.

[0013] FIG1A schematically shows a mobile device numbered 100, which includes a known POC 110 in a first state (“retracted state”) when the camera is not in use. In the retracted state, the POC 110 has a first TTL (“retracted TTL” or “cTTL”). The cTTL is compatible with the height dimensions of modern mobile devices, i.e., the POC 110 does not exceed the height (or thickness) of the mobile device 100 in its retracted state.

[0014] Figure 1B schematically illustrates a mobile device 100 in which the POC 110 is in a second ("pop-up" or "PO") state, in which the POC is in an active (operable) state. Generally speaking, the POC is only operable as a camera in the pop-up state. In the PO state, the POC 110 has a "regular" PO state TTL (hereinafter referred to as "TTL"). In the PO state, the POC 110 protrudes (or "pops up") from the mobile device 100. Typically, the mobile device has a thickness T of about 5-15 mm. In the PO state, the POC can protrude from the mobile device 100 (i.e., exceed the thickness T of the mobile device 100) by about 1-10 mm. In the PO state, the POC 110 can have a TTL of about 8-25 mm, preferably about 10-20 mm. The ratio cTTL / TTL can be in the range of 0.5-0.95.

[0015] POC 110 may be a wide-angle camera having: a wide-angle camera effective focal length EFL of approximately 8-20 mm W , wide-angle camera field of view FOV of about 60-100 degrees W (diagonal), a wide-angle camera sensor with a sensor diagonal SD of about 12-30 mm and a ratio cTTL / SD<0.8. POC 110 can also be a telephoto camera with: a telephoto camera EFL of about 10-30 mm T , telephoto camera FOV of about 20-50 degrees T , and the ratio TTL / EFL<1.1. POC 110 can also be an ultra-wide angle (UW) camera with a UW camera EFL of about 5mm-15mm UWAnd an ultra-wide-angle camera FOV of about 100-160 degrees UW .

[0016] 1C-1D schematically illustrate a cross-sectional view of a POC 110 in a retracted state and an extended state, respectively. The camera module 110 includes a lens barrel 112, a lens carrier (or simply referred to as a "carrier") 114 configured to receive the lens barrel 112, and an image sensor 116. The camera module 110 may also include a retractable cover window 118. The lens barrel 112 includes an objective lens assembly. The objective lens assembly may coaxially hold a plurality of (e.g., four to ten) lens elements 120, which define the optical axis Z of the camera module 110. The lens barrel 112 may be coaxially positioned on the inner side of the carrier 114. The lens barrel 112 may be coupled to the carrier 114 to allow the lens barrel 112 to be axially displaced relative to the carrier 114. The carrier 114 may not move axially relative to the image sensor 116, that is, it may be fixed relative to the Z axis.

[0017] The lens barrel 112 has a PO (or "activity", "operation" or "operable") state and a contraction or "inactive" state. In the operational state, the image sensor 116 is positioned at the focal plane or imaging plane of the objective lens assembly. The operational state of the lens barrel corresponds to the PO (activity) mode of the camera module 110.

[0018] The camera module 110 also includes a barrel PO assembly 122, which is configured to controllably move the lens barrel 112 from a collapsed state to an operational state, and bias (or push) the lens barrel 112 in the operational state. The PO assembly 122 can be configured to move the lens barrel 112 axially from a collapsed state toward an operational state relative to the carrier 114. The PO assembly 122 can be positioned in the gap (space) between the carrier 114 and the lens barrel 112. Such a gap can be formed by cutting the lens element 120 (i.e., performing D-cutting known in the art). When the lens barrel weight prevents the lens barrel 112 from moving axially from a collapsed state to an operational state, the PO assembly 122 can be configured to generate a PO force that can overcome the lens barrel weight. The retractable cover window 118 can be configured to controllably move axially between a retracted position and an extended position. In the retracted position, the cover window 118 can be positioned to abut the farthest surface (e.g., edge) of the lens barrel 112 in the collapsed state. In the extended position, the cover window 118 may be positioned with axial clearance from the outermost surface of the lens barrel 112 in an operative state.

[0019] The motion of cover window 118 between retracted and extended position and the motion of lens barrel 112 between retracted and extended position can be coordinated.The axial motion of cover window 118 can be driven by cover window PO assembly 124 operated by actuator 126.In the retracted position, cover window 118 can be configured to be maintained at lens barrel 112 in the retracted position.In the extended position, cover window 118 can be configured to have axial clearance with the lens barrel 112 in the operating state.Axial clearance can allow lens barrel 112 to carry out some axial motions from the operating state, thereby realize focusing (or automatic focusing "AF, autofocus"). Cover window 118 can also be configured to make lens barrel 112 move from the operating state to the retracted state when cover window 118 is operated by window cover pop-up assembly 124 to move from the extended position to the retracted position.In other words, when operating window cover PO assembly 124 and cover window 118 is moved from the extended position to the retracted position, window cover 118 can push lens barrel 112 and make lens barrel 112 shrink and be in the retracted state. When the cover window 118 moves from the retracted position to the extended position, the lens barrel 112 is released and the PO force generated by the PO assembly 122 can drive the lens barrel 112 toward the operational state.

[0020] FIG. 1E shows a top view of a known PO lens module (also referred to as an “optical frame”) numbered 130 disclosed in FIG. 18E of PCT / IB2020 / 058697. The PO lens module 130 can be used in a POC such as the POC 110. The PO lens module 130 includes an external component 132, an internal component 134, a lens barrel (not shown) such as the lens barrel 112, a PO assembly 140, and a PO lens (not shown). The PO assembly 140 includes three springs 142, 144, and 146 and three pin-and-slot mechanisms 148, 150, and 152. The pin-and-slot mechanisms 148, 150, and 152 together form a motion coupling mechanism between the external component 132 and the internal component 134. Springs 142 , 144 , and 146 provide an actuation force for PO assembly 140 that moves inner member 134 relative to outer member 132 , and the kinematic coupling mechanism provides mechanical precision and repeatability of PO assembly 140 when switching POC 110 from the PO state to the retracted state and vice versa.

[0021] Each of the springs 142, 144 and 146 has a spring diameter "d Spring As shown, the inner member 134 has an outer diameter ("di Outer ”) and inner diameter (“di Inner ”). The outer member 132 has an inner radius (“ Inner ”, not shown, see Figure 2A-2B). We note that the outer member 132 surrounds (or surrounds) the inner member 134 so that the do Inner Equal to or greater than di Outer .di Inner is limited by springs 142, 144 and 146, and it represents the maximum aperture diameter (“DA Max ”, as marked), i.e. DA Max =di Inner .di Outer and Inner The difference between is called the “diameter penalty” or simply “penalty” or “P”, where di Outer =DA Max +P. In the PO lens module 130, P may be about 1 mm <P<7.5mm。

[0022] In order to achieve a certain Outer For a POC that is compact and still has good performance, minimizing the penalty p is beneficial because it allows the DA Max maximizing the amount of light that can enter the POC and contribute to the POC signal. p is determined by the spring diameter d Spring Add a certain air gap "g" (usually g = 0.05mm-0.75mm) to give, that is, p = d Spring +g. p is produced by incorporating springs 142, 144 and 146 between the outer member 132 and the lens barrel. Springs 142, 144 and 146 are "closing" springs known in the art. Hereinafter, we refer to the actuation provided by the PO lens module 130 as "spring actuation".

[0023] FIG. 1F shows a perspective view and a top view of a known example of a known closing spring 160. Its shape is called a "closed" spring because it resembles a closed circle in a top view. The top view is a view in a direction perpendicular to the XY plane. The closing spring 160 has a spring diameter "d Spring ”.

[0024] FIG. 1G shows a top view of another known PO lens module numbered 170. In lens module 170, all entities and their labels have similar meanings as in lens module 130. PO lens module 170 can be used in a POC such as POC 110. PO lens module 170 includes an outer member 172, an inner member 174, a gap ("G") between inner member 172 and outer member 174, an actuator 176, and a PO lens (not shown). The width of G varies along the diameter of outer member 172 and inner member 174, with the maximum G width marked as "W". G-Max". The actuator 176 is operable to move the outer component 172 and the inner component 174 relative to each other along the PO lens optical axis 178 to switch the POC including the PO lens module 170 from the PO state to the retracted state, and vice versa. The PO lens optical axis 178 is oriented perpendicular to the xy axis defined by the coordinate system shown. The actuator 176 includes two springs 180 and 182. The springs 180 and 182 are "closing" springs. The springs 180 and 182 provide the actuating force of the actuator 176 when switching the POC including the PO lens module 170 from the PO state to the retracted state and from the retracted state to the PO state.

[0025] FIG. 1H schematically shows a cross-sectional view of a known POC numbered 190 disclosed in FIG. 18A-FIG. 18B of the co-owned international patent application PCT / IB2022 / 052194 in a retracted state. POC 190 includes a PO assembly 122, which includes at least one permanent magnet 192 fixed to the lens barrel 112 and a yoke 194 fixed to the carrier 114. PO assembly 122 represents a magnetic spring assembly. PO assembly 122 provides a magnetic force applied to yoke 194 through permanent magnet 192, generating a vertical bias force on lens barrel 112 in a spring manner. Therefore, hereinafter, we refer to the actuation provided by PO assembly 122 as "magnetic spring actuation". In the PO state and in cooperation with a coil (not shown), yoke 194 and magnet 192 provide a force for performing focusing.

[0026] It is advantageous to (1) use spring-actuated POCs that include compact springs, i.e., springs with a small spring diameter (or spring width) so that they only cause a small penalty value p, and (2) use magnetic spring-actuated POCs that have magnetic springs that exert a magnetic spring force that is not just limited by the strength of the magnet and yoke, which can also be operated for focusing. Such springs and their use in POCs are disclosed herein. Summary of the invention

The PO lens module 200 includes an outer component 202 separated from an inner component 204 by a gap G, an actuator 210, and a PO lens (not shown). The actuator 210 is operable to move the outer component 202 and the inner component 204 relative to each other along the PO lens optical axis 212 to switch the POC (and the lens) from a PO (operable) state to a retracted state, and vice versa.

The actuator 210 includes two springs 214 and 216 and three pin-slot mechanisms 218, 220, and 222. The mechanisms 218, 220, and 222 together form a motion coupling mechanism between the outer component 202 and the inner component 204. The springs 214 and 216 provide the actuation force when switching the camera (and lens) from the PO state to the retracted state and vice versa, and the kinematic coupling mechanism provides mechanical precision and repeatability for the actuator 210. The springs 214 and 216 are located within the gap G between the outer member 202 and the inner member 204. The width of the gap G varies along the diameter of the outer member 202 and the inner member 204, with the maximum G width being marked as "W". G-Max ”. G-Max It can be in the range of 0.25-5mm.

[0087] Note that the P-O lens (not shown here) may have a plurality of lens elements (N), which in some examples may be divided into two or more lens groups, as disclosed, for example, in the co-owned international patent applications PCT / IB2020 / 058697, PCT / IB2021 / 057311, PCT / IB2022 / 050575, PCT / IB2021 / 056358, PCT / IB2022 / 052194, PCT / IB2022 / 050594, and PCT / IB2022 / 056646.

[0088] d-o Inner = DA Max + p. In the P-O lens module 200, p may satisfy 0.25 mm < p < 5 mm, preferably 0.25 mm < P < 2.5 mm, or even 0.25 mm < p < 1 mm. As discussed, minimizing the penalty value p is beneficial because this maximizes DA Max The above p range in the lens module 200 is much smaller than the p range in the prior art modules.

[0089] DA Max refers only to the lens elements of the movable lens group. The "movable lens group" is a lens group that moves together with the internal component 204, such as a lens group fixedly coupled to the internal component 204. In other words, the movable lens group is a lens group that moves relative to the image sensor included in the POC when the POC switches between the P-O state and the retracted state. DA Max can be in the range of 3 mm < DA Max < 15 mm. In some examples, 5 mm < DA Max < 12.5 mm or 5 mm < DA Max < 10 mm. p is given by the spring width W Spring plus a certain air gap "a-g", i.e., p = d Spring + a-g. a-g can be, for example, about 0.05 - 0.75 mm. p is generated by combining springs 214 and 216 between the external component 202 and the internal component 204. Springs 214 and 216 can be, for example, springs 300, 400, 500, 600, 700, or 800, see Figure 3- Figure 8 These springs are referred to as "open" springs because in a top view, their shape presents two open ends. The advantage of the open springs over the closed springs (such as in Figure 1F) is that compared to the diameter d Spring of the closed spring, their spring width W Springis relatively small. Therefore, the opening spring allows a smaller penalty value p than the closing spring. Therefore, the PO lens module 200 and the opening springs 300, 400, 500, 600, 700 and 800 disclosed herein are beneficial for use in modern mobile devices such as smartphones.

[0090] In some embodiments, the PO lens module 200 moves perpendicular to the PO lens optical axis 212 (i.e., in the x-direction and / or the y-direction) for optical image stabilization ("OIS"). The movement of the PO lens module 200 is relative to the image sensor. In other embodiments, the image sensor can be moved perpendicular to the PO lens optical axis 212 and relative to the PO lens module 200 for OIS.

[0091] Figure 2B Show Figure 2A 2 is a perspective exploded view of the PO lens module 200. The opening springs 214 and 216 are visible. The slot 224 of the pin-slot mechanism 220, the pin 226 of the pin-slot mechanism 218, and the pin 228 of the pin-slot mechanism 220 are also visible.

[0092] Figure 3A A top view of a first example of an open spring numbered 300 disclosed herein is shown. Figure 3B Show Figure 3A 300 is a perspective view of an open spring 300. Arrow 302 indicates the working direction of the spring 300 along which it applies force (parallel to the Z axis). The spring 300 is shown in a contracted state. The spring 300 is a "1-fold open spring". Spring Can meet 1mm <L Spring <15mm, W Spring Can meet 0.1mm <W Spring <1mm, and cH Spring Can meet 1mm <c-H Spring <15 mm. “Bend” refers to the shape of the spring 300 in a top view, and “1-fold” refers to the number of folds (here 1) of the spring 300 in a direction perpendicular to its working direction.

[0093] 1- The advantage of the folding spring is that it will not buckle. Buckling refers to the unexpected sudden change in shape of a structural member under load.

[0094] The opening spring 300 is operable for use in a PO lens module such as the PO lens module 200. This is also the case for all other opening spring examples disclosed herein, i.e., all springs 300, 400, 500, 600, 700, and 800 are operable for use in such a PO lens module. In a PO module including the opening spring 300, the working direction of the opening spring 300 is oriented parallel to the optical axis of the lens included in the PO module (such as the optical axis 212, see Figure 2A ). This is also the case for all other opening spring examples disclosed herein, i.e., in a PO module comprising an opening spring 300, 400, 500, 600, 700 or 800, respectively, the working direction of the opening spring 300, 400, 500, 600, 700 or 800 is oriented to be parallel to the optical axis of the lens (e.g. 212), respectively.

[0095] Figure 4A A top view of a second example of an open spring numbered 400 disclosed herein is shown. Figure 4B Shows the PO status Figure 4A Two different perspective views of the open spring 400. The height H of the spring 400 in the PO state Spring Can meet 2mm <H Spring <20 mm. Arrow 402 indicates the working direction of spring 400 along which it applies force. Figure 4C Shown in a contracted state Figure 4A and Figure 4B Two different perspective views of the opening spring 400. Spring "Can meet 1mm <c-H Spring <15mm. Ratio H Spring / cH Spring Can meet 1 / 4 <H Spring / cH Spring <3 / 4. Spring 400 is a "1-fold bent conical open spring" and has a spring length "L Spring ” and by the maximum spring width “W1 Spring " and the minimum spring width "W2 Spring ” indicates a continuously varying spring width, as marked. “Tapered” refers to a continuously varying spring width of spring 400, as shown in the top view ( Figure 4A ) is shown in FIG. Compared to a non-tapered open spring such as spring 300, a tapered open spring such as spring 400 has the advantage that the stress acting on the open spring is along L Spring More even distribution makes the open spring more efficient. W2 Spring Can be greater than W1 Spring / 10 and less than W1 Sprin g / 2.W1Spring It can be larger than 0.1 mm and smaller than 2 mm.

[0096] Figure 5A A top view of a third example of an open spring numbered 500 disclosed herein is shown. Figure 5B Show Figure 5A A first perspective view of an opening spring 500 . Figure 5C Show Figure 5A and Figure 5B 500. Arrow 502 indicates the working direction of spring 500 along which it applies force. Spring 500 is a "1-fold 2-snake-bend tapered open spring" and is shown in a contracted state. Spring 500 has a spring length "L Spring "、Contraction spring height (cH Spring ) and by the maximum spring width "W1 Spring " and by the minimum spring width "W2 Spring ” indicates a continuously varying spring width, as marked. “2-Snake” refers to the spring width in the top view ( Figure 5A ) in the two folds of spring 500. An advantage of a serpentine opening spring (such as spring 500) over a non-serpentine opening spring (such as spring 400) is that for a given L Spring , H Spring and W2 Spring , the spring is more elastic, which allows the spring to have a larger PO stroke (i.e. H Spring and cH Spring For example, a 5%-50% greater PO travel may be achieved compared to previous open spring configurations (such as, for example, spring 400).

[0097] Fig. 6A A top view of a fourth example of an open spring disclosed herein and numbered 600 is shown. The open spring 600 is shown in the PO state. Figure 6B Show Fig. 6A Side view of the opening spring 600. Figure 6C Show Figure 6A-6B 600 is a perspective view of an open spring 600. Arrow 602 indicates the working direction of the spring 600 along which it applies force. The spring 600 is a "7-fold straight open spring". "7-fold" refers to the seven folds of the spring 600 as seen in the top view, and "straight" refers to the straight shape of the spring 600 as seen in the top view ( Fig. 6A ). Spring Can be larger than 1mm and smaller than 15mm, W Spring Can be greater than 0.1mm and less than 1mm, and H Spring It can be larger than 1mm and smaller than 20mm.

Arrow 702 indicates the working direction of spring 700 along which force is applied. Spring 700 is a "1-fold 4-serpentine open spring". Spring Can be larger than 1mm and smaller than 15mm, and cH Spring It can be larger than 1mm and smaller than 15mm.

[0099] Figure 8 A perspective view of a seventh example of an open spring disclosed herein, numbered 800, is shown. Arrow 802 indicates the working direction along which spring 800 applies force. Spring 800 is a "1-fold 3-winding bent open spring," as labeled. "3-winding" refers to the number of windings of spring 800 relative to an axis that is perpendicular to the length L along which spring 800 is measured. Spring The axis of L Spring Can be larger than 1mm and smaller than 15mm, and cH Spring It can be larger than 1 mm and smaller than 15 mm. The advantage of the opening spring 800 is that it is relatively simple to manufacture.

[0100] Fig. 9A A cross-sectional view of a POC numbered 900 including a PO assembly 902 disclosed herein in a contracted state is schematically shown. The PO assembly 902 is configured to controllably move the lens barrel 112 from the contracted state to the operational state, and bias the lens barrel 112 in the operational state. The known PO assembly 122 (FIG. 1G), PO assembly 902 includes at least one first permanent magnet 192 fixed to the lens barrel 112 and a yoke 194 fixed to the carrier 114. In addition, the PO assembly 902 includes a second permanent magnet 904 fixed to the lens barrel 112 and a third permanent magnet 906 fixedly coupled to the carrier 114. When the lens barrel 112 moves axially, the second magnet 904 interacts with the third magnet 906. Neither the second magnet 904 nor the third magnet 906 interacts with the magnet 192 and the yoke 194. In other words, two independent forces are used to axially move the lens barrel 112, the first force generated by the interaction of the first magnet 192 and the yoke 194, and the second force generated by the interaction of the second magnet 904 and the third magnet 906. PO assembly 902 represents a first configuration of a "magnetic spring with a repelling magnet" disclosed herein. In some examples and as Fig. 9AAs shown, magnet 904 and magnet 906 are located on the opposite side of lens barrel 112 from magnet 192 and yoke 194, where "opposite side" refers to the position or sequence along the x-axis. In other examples and with reference to magnet 192 and yoke 194, magnet 904 and magnet 906 can be located on different sides of lens barrel 112, for example, they can be located in front of lens barrel 112 or "behind", where "front" and "behind" refer to the position or sequence along the y-axis.

[0101] Fig. 9B A cross-sectional view of a POC numbered 910 including a PO assembly 912 disclosed herein in a retracted state is schematically shown. The PO assembly 912 is configured to controllably move the lens barrel 112 from the retracted state to the operational state, and bias the lens barrel 112 in the operational state. The PO assembly 912 includes a second permanent magnet 914 fixedly coupled to the carrier 114. The magnet 914 is located on the same side of the lens barrel 112 as the first magnet 192 and the yoke 194. The "same side" here refers to the position or sequence along the x-axis. When the lens barrel 112 moves axially, the magnet 914 interacts with the magnet 192. In other words, two independent forces are used to axially move the lens barrel 112, the first force is generated by the interaction of the magnet 192 and the yoke 194, and the second force is generated by the interaction of the magnet 192 and the magnet 914. The PO assembly 912 represents a second configuration of the "magnetic spring with a repelling magnet" disclosed herein.

[0102] For both the first and second configurations of the "magnetic spring with a repelling magnet", in the PO state and in cooperation with a coil (not shown), the yoke 194 and the magnet 192 provide a force for performing focusing of the POC 900 and the POC 910, respectively. When focusing, the lens barrel 112 moves parallel to the z-axis, or in other words, the lens barrel 112 moves parallel to the lens optical axis of the lens (not shown) included in the lens barrel 112. In other examples for focusing, the image sensor included in the POC moves parallel to the z-axis and relative to the lens barrel 112.

[0103] exist Figures 9A-9B , 10A-10B, 11A-11B, 12A-12B and 13A-13B, the lens optical axis of the lens (not shown) is oriented parallel to the z-axis.

[0104] Fig. 10A 1000 is a cross-sectional view of a PO assembly disclosed herein in a collapsed state. PO assembly 1000 represents a first configuration of a "magnetic spring with a repelling magnet" ( Fig. 9A). PO assembly 1000 includes: a barrel 1002, a first permanent magnet 1012 fixedly coupled to the barrel 1002, a second permanent magnet 1016 fixedly coupled to the barrel 1002, a third permanent magnet 1018 fixedly coupled to a carrier (not shown), and a yoke 1006 fixedly coupled to the carrier (not shown). The interaction of the first magnet 1012 and the yoke 1006 produces a first force ("F1") directed parallel to the z-axis and pointing upward, as shown by arrow 1014. The interaction of the second magnet 1016 and the third magnet 1018 produces a second force ("F2") directed parallel to the z-axis and pointing upward, as shown by arrow 1020. In the retracted state, both F1 and F2 are relatively large, as indicated by the relatively large size (or length) of arrows 1014 and 1020. In addition, the PO assembly 1000 includes a printed circuit board (PCB) 1004 and a coil 1008 and a magnetic flux sensor (e.g., a Hall bar sensor) 1010 fixedly coupled to the PCB 1004. The PCB 1004 is fixedly coupled to a carrier (not shown). The magnetization (or "magnetic polarization" or "direction of magnetic flux") of the permanent magnets is indicated by arrows in the corresponding permanent magnets, namely as follows: the upper half (relative to the z-axis) 1012a of the magnet 1012 is magnetized parallel to the x-axis, and the magnetization vector points away from the lens barrel 1002. The lower half (relative to the z-axis) 1012b of the magnet 1012 is magnetized parallel to the x-axis, and the magnetization vector points toward the lens barrel 1002. The second magnet 1016 is magnetized parallel to the z-axis, and the magnetization vector points downward, that is, toward the image sensor (not shown) included in the POC including the PO assembly 1000. The third magnet 1018 is magnetized parallel to the x-axis as shown, with the magnetization vector pointing toward the column 1002 .

[0105] Fig. 10B With Fig. 10A The same view shows the PO assembly 1000 in the PO state. In the PO state, both F1 and F2 are relatively small, as indicated by the relatively small size of arrow 1014 and arrow 1020. For F1, this is caused by the first magnet 1012 and the yoke 1006 being closer to the equilibrium position than in the retracted state. For F2, this is caused by the second magnet 1016 and the third magnet 1018 being further away from each other than in the retracted state.

[0106] Fig.11A 1 shows a cross-sectional view of a PO assembly disclosed herein, numbered 1100, in a contracted state. PO assembly 1100 represents a first configuration of a "magnetic spring with a repelling magnet" ( Fig. 9A). PO assembly 1100 is the same as PO assembly 1000 except for the difference in the second permanent magnet and the third permanent magnet. PO assembly 1100 includes a second permanent magnet 1102 fixedly coupled to the lens barrel 1002 and a third permanent magnet 1104 fixedly coupled to the carrier (not shown). The interaction of the first magnet 1012 and the yoke 1006 produces a first force ("F1"). The interaction of the second magnet 1102 and the third magnet 1104 produces a second force ("F2") directed parallel to the z-axis and pointing upward, as shown by arrow 1106. In the retracted state, both F1 and F2 are relatively large, as indicated by the relatively large size of arrows 1014 and 1106. The second magnet 1102 is magnetized parallel to the z-axis, with the magnetization vector pointing downward, i.e., toward the image sensor (not shown). The third magnet 1104 is magnetized parallel to the z-axis, with the magnetization vector pointing upward, as shown.

[0107] Fig. 11B With Fig.11A The same view shows the PO assembly 1100 in the PO state. In the PO state, both F1 and F2 are relatively small, as indicated by the relatively small size of arrow 1014 and arrow 1106. For F2, this is due to the second magnet 1102 and the third magnet 1104 being further away from each other than in the retracted state.

[0108] Fig. 12A 1 shows a cross-sectional view of a PO assembly disclosed herein, numbered 1200, in a contracted state. PO assembly 1200 represents a second configuration of a "magnetic spring with a repelling magnet" ( Fig. 9B ). In addition to the above components, PO assembly 1200 also includes a second permanent magnet 1202 fixedly coupled to a carrier (not shown). The interaction of second magnet 1202 and first magnet 1012 generates a second force ("F2") directed parallel to the z-axis and pointing upward, as shown by arrow 1204. In the retracted state, both F1 and F2 are relatively large, as indicated by the relatively large size of arrow 1014 and arrow 1204. Second magnet 1202 is magnetized parallel to the x-axis, with the magnetization vector pointing toward barrel 1002.

[0109] Fig. 12B With Fig. 12A The same view shows the PO assembly 1200 in the PO state. In the PO state, both F1 and F2 are relatively small, as indicated by the relatively small size of arrow 1014 and arrow 1204. For F2, this is caused by the second magnet 1202 and the first body 1012 being further away from each other than in the retracted state.

[0110] In a POC including one of the PO assembly 1000, the PO assembly 1100 or the PO assembly 1200, the yoke 1006, the coil 1008, the first magnet 1012 and (optionally) the magnetic flux sensor 1010 may constitute a voice coil motor (VCM). The VCM may be operated to axially move a lens barrel 1002 including a lens (not shown) parallel to the z-axis and relative to a carrier (not shown) for focusing.

[0111] Fig.13A 1300 is a cross-sectional view of the PO assembly disclosed herein in a collapsed state. PO assembly 1300 represents a second configuration of a "magnetic spring with a repelling magnet" ( Fig. 9B ). In addition to the above components, the PO assembly 1200 also includes a first permanent magnet 1302 fixedly coupled to the lens barrel 1002 and a second permanent magnet 1304 fixedly coupled to the carrier (not shown). The interaction between the first magnet 1302 and the yoke 1006 produces a first force ("F1") directed parallel to the z-axis and pointing upward, as shown by arrow 1306. The interaction between the first magnet 1302 and the second magnet 1304 produces a second force ("F2") directed parallel to the z-axis and pointing upward, as shown by arrow 1308. In the retracted state, both F1 and F2 are relatively large, as indicated by the relatively large sizes of arrows 1306 and 1308. The first magnet 1302 is magnetized parallel to the z-axis, with the magnetization vector pointing downward, that is, toward the image sensor (not shown). The second magnet 1304 is magnetized parallel to the z-axis, with the magnetization vector pointing upward.

[0112] Fig. 13B With Fig.13A The same view shows the PO assembly 1300 in the PO state. In the PO state, both F1 and F2 are relatively small, as indicated by the relatively small size of arrow 1306 and arrow 1308. For F1, this is caused by the first magnet 1302 and the yoke 1006 being closer to the equilibrium position than in the retracted state. For F2, this is caused by the first magnet 1302 and the second magnet 1304 being further away from each other than in the retracted state.

[0113] In a POC including the PO assembly 1300, the yoke 1006, the coil 1008, the first magnet 1302 and (optionally) the magnetic flux sensor 1010 may form a VCM. The VCM is operable to move the barrel 1002 including the lens (not shown) axially parallel to the z-axis and relative to the carrier (not shown) for focusing.
