Description

All-in-one spring for simultaneous support of AF carrier and OIS carrier and camera module with built-in all-in-one spring

[0001] The present invention relates to a camera module mounted on a portable electronic device, and more specifically, to an all-in-one spring for simultaneously supporting an AF carrier and an OIS carrier, and a camera module having the all-in-one spring built in, in which the AF carrier and the OIS carrier are supported by a single all-in-one spring, thereby reducing the number of parts, simplifying the structure and simplifying the assembly process.

[0002] Cameras in recently released smartphones and other portable electronic devices incorporate a variety of cutting-edge technologies. These include features like autofocusing, which automatically focuses the camera more quickly, and image stabilization.

[0003] Image stabilization is a function that helps obtain a relatively good image even when the mobile electronic device shakes when taking a picture. Electronic and optical image stabilization are known.

[0004] Electronic image stabilization technology is a technology that improves the captured image through a process using software, etc., and optical image stabilization (OIS) technology is a technology that prevents shaking from being reflected in the image of the subject generated on the image sensor by physically correcting the position of the lens module or image element caused by hand shaking, etc.

[0005] However, while optical image stabilization technology can be easily applied to digital cameras with relatively ample internal space, its application is limited in devices with limited internal space, such as smartphones. This necessitates the development of smaller image stabilization devices.

[0006] Meanwhile, optical image stabilization devices include springs that elastically support the lens module. These springs help to quickly return the lens module to its original position on the optical axis when it is momentarily dislocated due to an external impact. Various types of springs exist for this purpose. However, conventional springs have the disadvantage that fatigue can easily accumulate and be transmitted due to changes in curvature as the lens module moves repeatedly.

[0007] As a background technology for an invention related to a camera module having an anti-shake function, domestic patent registration No. 10-1543717 (OIS camera module) has been disclosed.

[0008] The disclosed camera module includes a lens bobbin portion on which a lens is mounted; a horizontal actuator that moves the lens bobbin portion in a horizontal direction perpendicular to an optical axis; a sensor portion that detects the amount of horizontal movement of the lens bobbin portion by the horizontal actuator; a main body that surrounds the lens bobbin portion; and an intermediate unit having the vertical actuator that moves the lens bobbin portion in the optical axis direction and the lens bobbin portion, wherein the horizontal actuator is provided with an OIS coil that is installed in one of the intermediate unit and the main body, and an OIS magnet that is installed in the other of the intermediate unit and the main body, and the sensor portion, the OIS coil, and the OIS magnet are provided at different positions in the optical axis direction, and the OIS magnet is provided between the sensor portion and the OIS coil. However, the above-described conventional OIS camera module has the disadvantages of being thick and having a suspension that can be easily separated upon external impact.

[0009] The present invention provides a camera module having an all-in-one spring for supporting both the AF carrier and the OIS carrier simultaneously, which has a reduced number of parts, thus simplifying the structure and simplifying the assembly process.

[0010] As a solution to the problem of achieving the above object, the camera module of the present invention, which has an all-in-one spring for simultaneous support of an AF carrier and an OIS carrier, comprises: a housing having an upper open receiving space and an optical path formed therein; an OIS carrier mounted in the receiving space of the housing and capable of moving in a direction perpendicular to the optical axis direction and having an installation space corresponding to the optical path; an AF carrier accommodated in the installation space and capable of adjusting its position in the optical axis direction; a lens module mounted on the AF carrier; a driving unit that moves the AF carrier in the optical axis direction and moves the OIS carrier when the OIS carrier is eccentric to align the center of the lens module with the center of the optical path of the housing; and an all-in-one spring that is simultaneously coupled to the housing, the OIS carrier, and the AF carrier, and elastically restrains the AF carrier and the OIS carrier so that the central axis of the lens module is parallel to the optical axis and also acts to align with the center of the optical path.

[0011] In addition, the housing, OIS carrier, and AF carrier are provided with first, second, and third fixing parts, respectively, and the all-in-one spring has a housing coupling part coupled to the first fixing part, an OIS carrier coupling part coupled to the second fixing part, and an AF carrier coupling part coupled to the third fixing part, and a bending part that elastically deforms according to the movement of the OIS carrier is formed between the housing coupling part and the OIS carrier coupling part.

[0012] In addition, the housing coupling portion, the OIS carrier coupling portion, and the AF carrier coupling portion take the shape of a thin plate of a certain thickness and are positioned on the same plane, and the bending portion is formed at a position lower than the plane while forming an integral part with both ends of the housing coupling portion and the OIS carrier coupling portion.

[0013] In addition, a bending portion receiving groove for receiving the bending portion is further formed in the OIS carrier.

[0014] In addition, the bending portion takes the shape of a U, V, W, or ring.

[0015] In addition, the AF carrier coupling part has a driving arm that is integrally formed with the OIS carrier coupling part and extends horizontally to provide elasticity to the AF carrier, and a terminal fixing tab formed at an extended end of the driving arm and coupled to a third fixing part of the AF carrier.

[0016] The camera module of the present invention, which is formed as described above and has an all-in-one spring for simultaneous support of the AF carrier and the OIS carrier, has an all-in-one spring that elastically supports the AF carrier and the OIS carrier simultaneously, so the number of parts is reduced, the structure is simple, and the assembly process is simplified.

[0024] Hereinafter, one embodiment according to the present invention will be described in more detail with reference to the attached drawings.

[0025] Basically, the camera module of the present invention, which has an all-in-one spring for simultaneous support of the AF carrier and the OIS carrier, has an optical image stabilization function and has an all-in-one spring built in. The all-in-one spring minimizes the influence of shaking of the camera module by simultaneously providing elasticity to the AF carrier and the OIS carrier. That is, it acts so that the central axis of the lens module (13) aligns with the optical axis. By applying the all-in-one spring, the number of parts can be reduced compared to the conventional camera module, which makes the structure simpler and the assembly process simpler.

[0026] Fig. 1 is a perspective view of a camera module (10) having an all-in-one spring for simultaneous support of an AF carrier and an OIS carrier according to one embodiment of the present invention. Fig. 2 is an exploded perspective view of the camera module illustrated in Fig. 1. In addition, Fig. 3 is an exploded view of the housing, the OIS carrier, the AF carrier, and the all-in-one spring of Fig. 2. Fig. 4 is a plan view illustrating the mounting state of the all-in-one spring illustrated in Fig. 2. In addition, Figs. 5 to 7 are drawings for explaining the operation of the all-in-one spring of Fig. 1.

[0027] As shown, the camera module (10) according to the present embodiment includes a housing (15), an OIS carrier (19), an AF carrier (21), a lens module (13), a driving unit, a pair of all-in-one springs (30), and a shield can (11).

[0028] The housing (15) provides an upper open receiving space (15b) and has an optical passage (15c) in the center of the bottom. The housing (15) has a roughly square frame shape and is wrapped around a circuit board (17) that is part of the driving unit.

[0029] The driving unit is responsible for the basic function of moving the AF carrier (21) in the direction of the optical axis and, when the OIS carrier (19) is eccentric, moving the OIS carrier to align the center of the lens module (13) with the center of the optical path of the housing.

[0030] That is, the OIS carrier (19) may become eccentric, tilted in a direction orthogonal to the optical axis, or rotate around the optical axis due to shaking. When such unnecessary movement occurs, the OIS carrier (19) returns to its normal position (almost instantaneously). This return of the OIS carrier (19) to its normal position is also due to the action of the all-in-one spring (30). In other words, the all-in-one spring (30) assists the driving unit.

[0031] For reference, the driving unit moves the AF carrier (21) in the optical axis direction to focus the camera on the subject.

[0032] The driving part includes a circuit board (17), an X driving coil (17a), a Y driving coil (17b), first and second sensors (17e, 17f), an AF coil (21k), and four magnets (19g).

[0033] The circuit board (17) is a flexible printed circuit board (FPCB) in the form of a band and is tightly fixed to the outer surface of the housing (15). In addition, the circuit board (17) is provided with a terminal portion (not shown). The terminal portion is a portion that receives power from the outside.

[0034] The X drive coil (17a) and the Y drive coil (17b) are connected to the circuit of the circuit board (17) and are exposed toward the inside of the housing (15). The X drive coils (17a) face each other with the optical path (15c) in the middle. The Y drive coils (17b) also face each other with the optical path (15c) in between. The connecting lines connecting the mutually opposing X drive coils (17a) and the connecting lines connecting the Y drive coils (17b) are orthogonal to each other.

[0035] The first and second sensors (17e, 17f) are respectively arranged on the inner side of the X drive coil (17a) and the inner side of the Y drive coil (17b). The first and second sensors (17e, 17f) detect the movement of the OIS carrier (19). That is, the first sensor (17e) detects the X-direction movement of the OIS carrier (19), and the second sensor (17f) detects the Y-direction movement of the OIS carrier (19).

[0036] In addition, the AF coil (21k) is arranged on the outer surface of the AF carrier (21). The AF coil (21k) is connected to a terminal provided within the housing via an all-in-one spring (30). When the AF carrier (21) is mounted in the installation space (19c) of the OIS carrier (19), the AF coil (21k) is arranged opposite to four magnets (19g).

[0037] Finally, when the OIS carrier (19) and the AF carrier (21) are positioned correctly within the housing (15), the AF coil (21k) and the X, Y drive coils (17a, 17b) face each other with the magnet (19g) between them. The AF coil (21k) and the X, Y drive coils (17a, 17b) share the magnet (19g).

[0038] The AF coil (21k), X drive coil (17a), and Y drive coil (17b) output electromagnetic force by power applied through the circuit board (17), and affect the facing magnet (19g).

[0039] That is, when current is applied to the X drive coil (17a), the OIS carrier (19) moves in the X direction, and when current is applied to the Y drive coil (17b), the OIS carrier (19) moves in the Y direction. The application of current to the X drive coil (17a) and the Y drive coil (17b) is performed when the first and second sensors (17e, 17f) detect the movement of the OIS carrier (19) due to the shaking of the camera module (10). In addition, when current is applied to the AF coil (21k), movement in the optical axis direction occurs according to Fleming's left-hand rule.

[0040] The shield can (11) is a cover that is detachably connected to the housing (15) and has a passage (11a) in the center. The shield can (11) serves to protect the components housed in the housing (15).

[0041] Meanwhile, a first protrusion (15a) as a first fixing member is formed on the upper surface of the four corners of the housing (15). The first protrusion (15a) is a cylindrical protrusion protruding upward and is inserted into a fixing hole (31a) provided in the housing coupling part (31) of the all-in-one spring (30). The first protrusion (15a) fixes the housing coupling part (31) to the upper surface of the housing (15) while being inserted into the fixing hole (31a).

[0042] The OIS carrier (19) is capable of moving in a direction orthogonal to the optical axis while mounted within the housing's receiving space, and has an installation space (19c) corresponding to the optical path (15c). The OIS carrier (19) includes a square-shaped carrier body (19a) and four magnets (19g). The magnets (19g) are permanent magnets, and the details thereof are as described above.

[0043] The carrier body (19a) is molded and manufactured from synthetic resin and is inserted into the receiving space (15b) of the housing (15). The installation space (19c) is a space for receiving the AF carrier (21). In addition, two second protrusions (19d) are formed at each of the four corners of the upper surface of the carrier body (19a). The second protrusions (19d) are second fixing parts that are inserted into the fixing holes (35a) formed in the OIS carrier coupling part (35) of the all-in-one spring (30). By inserting the second protrusions (19d) into the fixing holes (35a), the OIS carrier coupling part (35) is maintained in connection with the OIS carrier (19).

[0044] In addition, a bending portion receiving groove (19b) is further formed on the outer side of the second protrusion (19d). The bending portion receiving groove (19b) is a space open upward and, as illustrated in Fig. 2, receives the bending portion (32) of the all-in-one spring (30). The bending portion (32) is received in the bending portion receiving groove (19b), but does not contact the inner surface of the bending portion receiving groove (19b).

[0045] The AF carrier (21) is accommodated within the installation space (19c) and can be positioned in the optical axis direction according to the direction of the current induced in the AF coil (21k). The AF carrier (21) has a carrier body (21a) and an AF coil (21k).

[0046] The carrier body (21a) is molded and manufactured from synthetic resin and has four fixing grooves (21e) on the upper surface. The fixing grooves (21e) are third fixing parts that are respectively combined with the AF carrier coupling parts (37) of the all-in-one spring (30). The four fixing grooves (21e) are arranged at a 90-degree angle. In addition, a lens module fixing space (21b) is provided in the carrier body (21a). The lens module fixing space (21b) is a space for receiving and fixing the lens module (13). The lens module (13) forms one body with the AF carrier (21) and moves together.

[0047] The all-in-one spring (30) is a pair of two, and is symmetrical with respect to the lens module (13). The all-in-one spring (30) is simultaneously coupled to the housing (15), the OIS carrier (19), and the AF carrier (21), and elastically restrains the AF carrier and the OIS carrier so that the central axis of the lens module (13) is parallel to the optical axis and coincides with the center of the optical path.

[0048] The 'optical axis' refers to a straight line component of incident light from a subject to an image sensor (not shown) (installed at the bottom of the optical path (15c) of the housing (15)), and means a direction perpendicular to the image sensor. In addition, the 'central axis' of the lens module is a straight line connecting the centers of multiple lenses built into the lens module. In the standby state (a state in which no external force is applied), the 'central axis' passes through the center point of the optical path (15c). In addition, the 'center point' of the optical path is the center of a circle drawn by the inner surface of the optical path.

[0049] The all-in-one spring (30) can be manufactured from various materials, for example, it can be manufactured from rolled copper foil material or spring material.

[0050] In the all-in-one spring (30), the housing coupling part (31), the OIS carrier coupling part (35), and the AF carrier coupling part (37) are formed integrally.

[0051] Each housing coupling part (31) is mounted on the upper surface of the four corners of the housing (15) and is a part that is coupled to the first fixing part, i.e., the first protrusion (15a). A fixing hole (31a) is formed in the housing coupling part (31) for coupling with the first protrusion (15a). When the fixing hole (31a) is fitted into the first protrusion (15a), the housing coupling part (31) is mounted to the first protrusion (15a).

[0052] The OIS carrier coupling portion (35) is a portion installed on the upper surface of the facing side of the OIS carrier (19) and has two fixing holes (35a) at each end. The fixing holes (35a) are holes for receiving the second protrusion (19d). By inserting the second protrusion (19d) into the fixing holes (35a), the fixing of the OIS carrier coupling portion (35) to the OIS carrier (19) is completed.

[0053] In addition, the AF carrier coupling portion (37) is a portion supported by the third fixed portion formed in the AF carrier (21), i.e., the fixed groove (21e), and has a driving arm (37a) and a terminal fixing tab (37b).

[0054] The drive arm (37a) is an arc-shaped member that is integrally formed with the OIS carrier coupling portion (35), extends horizontally, and provides elasticity to the AF carrier (21). In this drawing, the drive arm (37a) takes the shape of an arc, but is not limited to an arc. For example, it may have a straight line or other shape.

[0055] The terminal fixing tab (37b) is formed at the extended end of the driving arm (37a) and is inserted and fixed into the fixing groove (21e) formed in the AF carrier. The AF carrier coupling portion (37) is elastically deformed up and down as the AF carrier (21) moves in the optical axis direction. The terminal fixing tab (37b) is also connected to the AF coil (21k).

[0056] The above housing coupling part (31), OIS carrier coupling part (35), and AF carrier coupling part (37) take the shape of a thin plate of a certain thickness and are located on the same plane.

[0057] Meanwhile, a bending portion (32) is positioned between the housing coupling portion (31) and the OIS carrier coupling portion (35). The bending portion (32) elastically deforms according to the movement of the OIS carrier (19). For example, when the OIS carrier (19) moves, tilts, or rotates in a direction orthogonal to the optical axis, it elastically changes and applies an elastic restoring force to the OIS carrier (19). The elastic restoring force refers to an elastic force that positions the OIS carrier (19) correctly.

[0058] The bending portion (32) is a wire-shaped member whose ends are integrally connected to the housing coupling portion (31) and the OIS carrier coupling portion (35), and has a shape bent approximately in a U shape. The bending portion (32) is located lower than the plane including the housing coupling portion (31) and the OIS carrier coupling portion (35). In other words, it protrudes downward between the housing coupling portion (31) and the OIS carrier coupling portion (35). As mentioned above, each bending portion (32) is accommodated in the bending portion accommodation groove (19b) of the OIS carrier (19).

[0059] Meanwhile, the drive arm, which is integrally formed with the OIS carrier coupling portion and extends horizontally to provide elasticity to the AF carrier, may have a smaller width than the OIS carrier coupling portion. This is because the drive arm is for the OIS function and may be formed to have a smaller width to provide better elasticity than the AF carrier.

[0060] As described above, the bending portion (32) elastically deforms according to the movement of the OIS carrier (19). FIG. 6 is a drawing showing the elastic deformation of the bending portion (32) when the OIS carrier coupling portion (35) moves in a direction orthogonal to the optical axis. The solid line in FIG. 6 represents the standby state, and the dotted line represents the state when elastically deformed.

[0061] Fig. 7 is a drawing showing an example of deformation of a bending portion in an all-in-one spring according to one embodiment of the present invention.

[0062] The bending portion (32) illustrated in Fig. 7a has a V-shape, and the bending portion (32) illustrated in Fig. 7b has an approximate W-shape. Furthermore, the bending portion (32) illustrated in Fig. 7c has a ring shape. The bending portion (32) illustrated in Fig. 8c is formed by rotating the portion of the all-in-one spring (30) material to be used as the bending portion by 540 degrees.

[0063] The shape of the bending portion (32) can vary as much as possible as long as it can elastically support the AF carrier (21) and the OIS carrier (19). For example, the bending portion (32) in the present embodiment is formed in a single line, but it can also be manufactured in two, three, or four or more lines. In addition, the width of the bending portion (32) can also be manufactured wider.

[0064] The operation of the camera module (10) of this embodiment having the above configuration is as follows.

[0065] First, when a user starts taking a picture using the camera function of a smartphone, the AF carrier (21) moves in the direction of the optical axis according to the distance to the subject. The all-in-one spring (30) also participates in the movement of the AF carrier (21). That is, the AF carrier connecting portion (37) of the all-in-one spring (30) is elastically deformed. While the AF carrier (21) moves, the OIS carrier (50) tries to maintain a fixed position by the action of the all-in-one spring (30). The fixed position means a position where the optical axis line coincides with the central axis of the optical path (15c).

[0066] However, when the camera module (10) shakes while taking a picture, the OIS carrier (19) moves and the bending part (32) of the all-in-one spring (30) is elastically deformed at the same time. In addition, the first and second sensors (17e, 17f) detect the movement of the OIS carrier (19). When the movement of the OIS carrier (19) is detected, the X drive coil (17a) and the Y drive coil (17b) operate at that moment to return the eccentric OIS carrier (19) to its original position. At this time, the bending part (32) is also elastically restored and assists in returning the OIS carrier (19) to its original position. By repeating the above process, the problem caused by the shaking of the camera module (10) is solved.

[0067] Above, the present invention has been described in detail through specific examples, but the present invention is not limited to the above examples, and various modifications are possible by a person of ordinary skill within the scope of the technical idea of ​​the present invention.

[0068] It can be used in portable electronic devices equipped with cameras.
