The lens assembly (210) may collect light emitted from a subject that is a target of image capturing. The lens assembly (210) may include one or more lenses. According to one embodiment, the camera module (180) may include a plurality of lens assemblies (210). In this case, the camera module (180) may form, for example, a dual camera, a 360-degree camera, or a spherical camera.

An image processed by the image signal processor (260) may be stored back in the memory (250) for further processing or provided to an external component of the camera module (180) (e.g., memory (130), display module (160), electronic device (102), electronic device (104), or server (108)). According to one embodiment, the image signal processor (260) may include at least one of the processors (120). It may be configured as a separate processor that is configured as a part of the processor (120) or operates independently of the processor (120). If the image signal processor (260) is configured as a separate processor from the processor (120), at least one image processed by the image signal processor (260) may be displayed through the display module (160) as is or after undergoing additional image processing by the processor (120).
[0051] According to one embodiment, the electronic device (101) may include a plurality of camera modules (180), each having different properties (e.g., angle of view) or functions. In this case, for example, the plurality of camera modules (180) may include at least one of a wide-angle camera, a telephoto camera, or an IR Camera (time of flight camera, structured light camera). For example, a plurality of camera modules including lenses having different angles of view are configured, and the electronic device may be controlled to change the angle of view variably according to a user's selection. According to one embodiment, at least one of the plurality of camera modules (180) may be a front camera, and at least another may be a rear camera.

In one embodiment, the camera module (300) may have a stacked structure of a substrate (380), an image sensor (381), an IR bracket (370) in which an IR filter (360) is arranged, a lower housing (350), a second spring member (SP2), an AF housing (340) in which a lens assembly (310) is accommodated, an upper housing (330), and a shield can (320), as illustrated in FIG. 4.
[0055] According to one embodiment, as illustrated in FIG. 4, the AF housing (340) may be a housing that accommodates the lens assembly (310). The AF housing (340) may be placed inside the lower housing (350) while accommodating the lens assembly (310). In one embodiment, the AF housing (340) may have an open upper surface so that the lens assembly (310) may be placed therein. In one embodiment, the lower housing (350) may have an open upper surface so that the AF housing (340) may be placed therein.
[0056] According to one embodiment, as illustrated in FIG. 4, the upper housing (330) may be coupled with the lower housing (350) to enclose the AF housing (340) and a portion of the lens assembly (310) accommodated in the AF housing (340). In one embodiment, the upper housing (330) may be formed to enclose the lens assembly (310) so as to accommodate at least a portion of the lens assembly (310) accommodated in the AF housing (340). As described below, the upper housing (330) may be coupled with the lower housing (350) such that a side wall (e.g., the second side wall (331) or the second bulkhead of FIG. 5A)) is disposed between side walls formed in the lower housing (350) (e.g., the third side wall (351), the fourth side wall (352) of FIG. 5A). In one embodiment, at least a portion of the second side wall (331) of the upper housing (330) (e.g., a side wall, a partition, a portion of the upper housing (330)) may protrude toward the lower housing (350) so as to cover at least a portion of one or more elastic members (400) disposed in the lower housing (350) when the camera module (300) is viewed from above (e.g., in the -Z direction of FIG. 4). For example, referring to FIG. 5A described below, a portion of the second side wall (331) of the upper housing (330) may extend toward the lens assembly (310). Accordingly, the one or more elastic members (400) may be at least partially covered by the second side wall (331) when the camera module is viewed from above (e.g., in the -Z direction of FIG. 5A).
[0057] According to one embodiment, with reference to FIGS. 3A, 3B, 4, and 5A described below, the lens assembly (310) may include at least one lens (312) and a lens barrel (311) (e.g., a barrel) in which the lens (312) is disposed. In one embodiment, the lens barrel (311) may be a housing that accommodates a plurality of lenses (312). In one embodiment, the plurality of lenses (312) may be arranged inside the lens barrel (311) along an optical axis of the lens (e.g., the Z-axis of FIG. 4).
[0058] In one embodiment, the lens assembly (310) is movable for auto focus (AF) to automatically adjust the focus of the lens (312) on a subject. In one embodiment, the lens assembly (310) can be moved along the optical axis with the AF housing (340) as the AF housing (340) moves along the optical axis (e.g., the Z-axis direction of FIG. 4) relative to the lower housing (350) to adjust the focus of the lens (312). In one embodiment, the camera module (300) can include an AF actuator that provides a driving force necessary to move the AF housing (340) along the optical axis relative to the lower housing (350). In one embodiment, the AF actuator can include an AF magnet (510) (e.g., a first drive magnet or a first magnet) and an AF coil (520) (e.g., a first drive coil or a first coil). In one embodiment, the AF housing (340) may be provided with either an AF magnet (510) or an AF coil (520). The other of the AF magnet (510) and the AF coil (520) may be disposed within the camera module (300) to face one of the AF magnets (510) and the AF coils (520) disposed within the AF housing (340). For example, as illustrated in FIG. 4, the AF coil (520) may be disposed along the periphery of the AF housing (340). The AF magnet (510) may be disposed within the shield can (320) to face the AF coil (520). However, as illustrated in FIG. 11A, the AF coils (620) (e.g., the AF coils (520)) may be configured in plurality and disposed to face each other within the AF housing (340). Similarly, the AF magnet (610) (e.g., the AF magnet (510)) may be configured in multiples to face the AF coil (620). The processor (120) may control the AF coil (520) to induce an electromagnetic phenomenon between the AF magnet (510) and the AF coil (520) and move the AF housing (340) in the optical axis direction relative to the lower housing (350).Accordingly, the camera module (300) can adjust the focus of the lens (312) as the lens assembly (310) disposed in the AF housing (340) moves in the optical axis direction together with the AF housing (340).
[0059] In one embodiment, the lens assembly (310) can be moved for an optical image stabilizer (OIS) to compensate for shake that occurs in the camera module (300) when capturing a subject. In one embodiment, the lower housing (350) can be disposed in a separate optical image stabilizer (OIS) housing (not shown). In one embodiment, the OIS housing can be disposed at least partially between the lower housing (350) and the IR bracket (370). In one embodiment, as the lower housing (350) moves in a direction substantially perpendicular to the optical axis (e.g., the X-axis direction and / or the Y-axis direction of FIG. 3A) relative to the OIS housing for image shake compensation or cancellation, the lens assembly (310) can be moved together with the lower housing (350) in a direction substantially perpendicular to the optical axis. In one embodiment, the camera module (300) may include an OIS actuator that provides a driving force necessary to move the lower housing (350) in a direction substantially perpendicular to the optical axis relative to the OIS housing. In one embodiment, the OIS actuator may include an OIS magnet (e.g., a second drive magnet or a second magnet) and an OIS coil (e.g., a second drive coil or a second coil). In one embodiment, one of the OIS magnet and the OIS coil may be disposed in one of the lower housing (350) and the OIS housing. The other of the OIS magnet and the OIS coil may be disposed in the other of the OIS housing and the lower housing (350) to face one of the OIS magnet and the OIS coil. The processor (120) may control the OIS coil to induce an electromagnetic phenomenon between the OIS magnet and the OIS coil and to move the lower housing (350) in a direction substantially perpendicular to the optical axis relative to the OIS housing.Accordingly, the camera module (300) can compensate for image shake as the lens assembly (310) moves in a direction in which image shake is canceled (e.g., perpendicular to the optical axis) together with the lower housing (350).
[0060] According to one embodiment, as illustrated in FIGS. 3A, 3B, and 4, the shield can (320) may be positioned at the outermost portion of the camera module (300) and at least partially surround the lower housing (350). In one embodiment, the shield can (320) may block or reduce electromagnetic waves generated from the outside of the camera module (300), thereby reducing malfunctions of the camera module (300). In one embodiment, the shield can (320) may be formed of a material that shields electromagnetic waves, such as copper, iron, aluminum, and / or nickel, and may be formed of various materials that can be performed by a person skilled in the art in addition to the materials described above.
[0061] According to one embodiment, as illustrated in FIG. 4, an upper housing (330) and an AF magnet (510) may be disposed inside the shield can (320). In one embodiment, at least a portion of the upper housing (330) may be disposed in the lower housing (350) while being coupled with the shield can (320) inside the shield can (320). For example, when the lower housing (350) containing the AF housing (340) is assembled with the shield can (320), a portion (e.g., the second side wall (331) of FIG. 5A) of the upper housing (330) disposed inside the shield can (320) may be disposed in a portion (e.g., the area between the third side wall (351) and the fourth side wall (352) of FIG. 5A) of the lower housing (350).
[0062] In one embodiment, the AF magnet (510) may be fixed inside the shield can (320). The AF magnet (510) may face the AF coil (520) disposed in the AF housing (340) when the shield can (320) is disposed in the lower housing (350) and a portion of the upper housing (330) is disposed in the lower housing (350). In one embodiment, the AF housing (340) may move in the optical axis direction through an electromagnetic force acting between the AF coil (520) and the AF magnet (510) to perform an AF (auto focus) function that automatically adjusts the focus of the lens (312) on a subject. In one embodiment, the AF magnet (510) may be disposed inside the shield can (320) so that its N pole and S pole face the AF coil (520) disposed in the AF housing (340). In this case, the AF housing (340) can be moved in the optical axis direction with respect to the lower housing (350) while maintaining a vertical distance between the AF coil (520) and the AF magnet (510). However, in the above description, the AF magnet (510) is described as being disposed inside the shield can (320) and the AF coil (520) is disposed in the AF housing (340), but this may not be limited thereto. For example, the AF coil (520) may be disposed inside the shield can (320), and the AF magnet (510) facing the AF coil (520) may be disposed in the AF housing (340). The AF magnet (510) may be disposed in the AF housing (340) so that its N pole and S pole may face the AF coil (520) disposed in the shield can (320). In this case, the AF housing (340) can be moved in the optical axis direction with respect to the lower housing (350) while maintaining a vertical distance between the AF coil (520) and the AF magnet (510).
[0063] In one embodiment not shown in the drawing, one of the AF coil (520) and the AF magnet (510) is disposed on the back surface of the AF housing (340) (e.g., the side facing the -Z direction in FIG. 4), and the other of the AF coil (520) and the AF magnet (510) is disposed on the lower housing (350) so as to face one of the AF coil (520) and the AF magnet (510). For example, when the AF coil (520) is disposed on the back surface of the AF housing (340), the AF magnet (510) may be disposed on the lower housing (350), and vice versa. In one embodiment, the AF magnet (510) may be disposed on the AF housing (340) or the lower housing (350) such that one of the N pole and the S pole faces the AF coil (520). In this case, the vertical distance of the AF magnet (510) to the AF coil (520) can be changed through the electromagnetic force acting on the AF coil (520). Accordingly, the AF housing (340) can perform an AF (auto focus) function that automatically adjusts the focus of the lens (312) on the subject by moving in the direction of the optical axis through the electromagnetic force acting between the AF coil (520) and the AF magnet (510).
[0064] In one embodiment, the camera module (300) may include a flexible printed circuit board (not shown) electrically connected to the AF coil (520) and / or the OIS coil. The processor (120) may be disposed on the main board (not shown) of the electronic device (101) and may supply current to the AF coil (520) through the flexible printed circuit board to provide a driving force in the direction of the optical axis to the AF housing (340). Furthermore, in one embodiment, the processor (120) may supply current to the OIS coil through the flexible printed circuit board to provide a driving force in the direction perpendicular to the optical axis to the lower housing (350).
[0065] According to one embodiment, as illustrated in FIG. 4, the camera module (300) may include a first spring member (SP1) and a second spring member (SP2) connected to the AF housing (340). In one embodiment, the first spring member (SP1) may be fixed to the upper housing (330) and the AF housing (340). For example, at least a portion of the first spring member (SP1) may be disposed in the upper housing (330) and a portion may be bonded to the AF housing (340) by welding or bonding using an adhesive member (e.g., tape, bond). In one embodiment, the second spring member (SP2) may be fixed to the lower housing (350) and the AF housing (340). For example, at least a portion of the second spring member (SP2) may be disposed in the lower housing (350) and a portion may be bonded to the AF housing (340) by welding or bonding using an adhesive member (e.g., tape, bond). In one embodiment, referring to FIG. 7c described below, one end (SP21) of the second spring member (SP2) may be fixed to the lower housing (350) via one or more elastic members (400).
[0066] In one embodiment, the first spring member (SP1) and the second spring member (SP2) can elastically support the movement of the AF housing (340) in the optical axis direction (e.g., the Z-axis direction of FIG. 4). In one embodiment, the AF housing (340) can perform an auto-focus function by moving in the optical axis direction through an electromagnetic force acting between the AF coil (520) and the AF magnet (510). Referring to FIG. 5A described below, when the AF housing (340) moves in the + Z direction of FIG. 5A, the first spring member (SP1) and the second spring member (SP2) can apply a spring force in a direction opposite to the movement of the AF housing (340) (e.g., the - Z direction of FIG. 5A). Conversely, when the AF housing (340) moves in the - Z direction of FIG. 5A, the first spring member (SP1) and the second spring member (SP2) can apply a spring force in a direction opposite to the movement of the AF housing (340) (e.g., the + Z direction of FIG. 5A). The spring members (SP1, SP2) can control the movement of the AF housing (340) due to external shock or vibration by applying a spring force in a direction opposite to the movement direction of the AF housing (340). In one embodiment, the AF housing (340) can be moved by the electromagnetic force between the AF coil (520) and the AF magnet (510), and then returned to the reference position before the movement by the spring force applied from the spring members (SP1, SP2) as the current applied to the AF coil (520) is cut off or reduced. The reference position may be the position of the AF housing (340) within the camera module (300) before the current is applied to the AF coil (520).
[0067] In one embodiment, the first spring member (SP1) and the second spring member (SP2) may be formed in various shapes and / or from various materials. In one embodiment, the first spring member (SP1) and the second spring member (SP2) may be formed as a plate spring. In one embodiment, the first spring member (SP1) may be formed of a metallic material such as stainless steel, beryllium copper, nickel copper, or carbon steel, and may be formed of a non-metallic material such as polyacetal, polycarbonate, carbon fiber, urethane, or rubber.
[0068] According to one embodiment, as illustrated in FIG. 4, an IR bracket (370) having an IR filter (360) disposed thereon and a substrate (380) having an image sensor (381) disposed thereon may be disposed at a lower portion of the lower housing (350). In one embodiment, the image sensor (381) may be disposed at a lower portion of the IR bracket (370) to face the IR filter (360). In one embodiment, the IR filter (360) may be a filter that selectively reflects or absorbs near-infrared wavelengths to block them from entering the image sensor (381). In one embodiment, the IR filter (360) may be disposed at the IR bracket (370) and between a lens (312) of the lens assembly (310) and the image sensor (381). The image sensor (381) can detect light emitted or reflected from a subject and transmitted through the lens assembly (310) - IR filter (360) and convert the light into an electrical signal, thereby obtaining an image corresponding to the subject. In one embodiment, the substrate (380) connected to the image sensor (381) can be electrically connected to a main substrate on which the processor (120) is disposed, which is electrically connected to the processor (120) through a connector.
[0069] FIG. 5A is a cross-sectional view taken along line 5A-5A of FIG. 3B. FIG. 5B is a drawing illustrating the arrangement relationship of the AF housing, elastic member, and lower housing of FIG. 5A. FIG. 6 is a perspective view of a camera module according to one embodiment of the present disclosure, with the upper housing, shield can, and lens assembly located above the AF housing removed.
[0070] According to one embodiment, as illustrated in FIGS. 5A and 5B , the AF housing (340) may include a first sidewall (341) (e.g., a sidewall, a partition, a portion, a first partition, or a first portion). In one embodiment, the first sidewall (341) may be a portion of an edge (e.g., a corner) of the AF housing (340). In one embodiment, the first sidewall (341) may face a portion of the lower housing (350) (e.g., a third sidewall (351)) when the AF housing (340) is disposed in the lower housing (350). In one embodiment, the lower housing (350) may include a third sidewall (351) (e.g., a third bulkhead, a third portion, a first sidewall of the lower housing (350), a first bulkhead of the lower housing (350), or a first portion of the lower housing (350)) and / or a fourth sidewall (352) (e.g., a fourth bulkhead, a fourth portion, a first sidewall of the lower housing (350), a first bulkhead of the lower housing (350), or a first portion of the lower housing (350). In one embodiment, the fourth sidewall (352) may be disposed outward with respect to the third sidewall (351). In one embodiment, the third sidewall (351) and / or the fourth sidewall (352) may be formed to extend in a direction perpendicular to a bottom surface (3511) of the lower housing (350) (e.g., a +Z direction with respect to FIG. 5A). In one embodiment, the third side wall (351) of the lower housing (350) may be formed at a position facing the first side wall (341) located at the corner of the AF housing (340) when the AF housing (340) is placed in the lower housing (350). In one embodiment, the first side wall (341) of the AF housing (340), the third side wall (351) of the lower housing (350), and the fourth side wall (352) of the lower housing (350) may be placed side by side when the AF housing (340) is placed in the lower housing (350).
[0071] According to one embodiment, as illustrated in FIG. 5A, the third side wall (351) and the fourth side wall (352) of the lower housing (350) may be positioned outside the image sensor (381) when the camera module (300) is viewed from above (e.g., in the -Z direction of FIG. 5A). In other words, the third side wall (351) and the fourth side wall (352) of the lower housing (350) may at least partially surround the image sensor (381) when the camera module (300) is viewed from above. In one embodiment, the bottom surface (3511) of the lower housing (350) may include a first support surface (3501) (e.g., the first support surface (3501) of FIG. 9A) positioned between the third sidewall (351) of the lower housing (350) and the first sidewall (341) of the AF housing (340), and a second support surface (3502) (e.g., the second support surface (3502) of FIG. 9A) positioned between the third sidewall (351) and the fourth sidewall (352) of the lower housing (350). In one embodiment, with reference to FIG. 7C described below, at least a portion of the second spring member (SP2) may be disposed on the first support surface (3501) and the second support surface (3502) of the lower housing (350), respectively. For example, a portion (SP22) of the second spring member (SP2) may be disposed on the second support surface (3502), and an end (SP21) extending from the portion (SP22) disposed on the second support surface (3502) may be disposed on the first support surface (3501). In one embodiment, the end (SP21) of the second spring member (SP2) may be in contact with one or more elastic members (400).
[0072] According to one embodiment, as illustrated in FIG. 5A, the upper housing (330) may include a second side wall (331) (e.g., a second partition or a second portion). In one embodiment, the upper housing (330) may be coupled to the lower housing (350) to accommodate the lens assembly (310) and the AF housing (340). In one embodiment, the second side wall (331) of the upper housing (330) may face the first side wall (341) positioned at the edge of the AF housing (340) when coupled with the lower housing (350). In one embodiment, at least a portion of the second side wall (331) of the upper housing (330) may protrude toward the lower housing (350) to cover at least a portion of the second spring member (SP2) disposed in the lower housing (350) when viewed from above the camera module (300). In one embodiment, the second sidewall (331) of the upper housing (330) may be positioned between the third sidewall (351) and the fourth sidewall (352) of the lower housing (350) when the upper housing (330) is coupled to the lower housing (350). In other words, the third sidewall (351) of the lower housing (350) may be positioned between the first sidewall (341) of the AF housing (340) and the second sidewall (331) of the upper housing (330). Accordingly, as illustrated in FIG. 5A, the first sidewall (341) of the AF housing (340) - the third sidewall (351) of the lower housing (350) - the second sidewall (331) of the upper housing (330) - the fourth sidewall (352) of the lower housing (350) may be positioned in this order.
[0073] According to one embodiment, as illustrated in FIGS. 5A, 5B, and 6, the camera module (300) may include one or more elastic members (400) disposed in a space (e.g., a gap) between a first side wall (341) of the AF housing (340) and a third side wall (351) of the lower housing (350). In one embodiment, the gap between the first side wall (341) of the AF housing (340) and the third side wall (351) of the lower housing (350) may be greater than or equal to about 0.2 mm and less than or equal to about 0.5 mm. In one embodiment, the one or more elastic members (400) may not be disposed between the second side wall (331) of the upper housing (330) and the third side wall (351) of the lower housing (350). In one embodiment, one or more elastic members (400) may be bonded to the first side wall (341) and the third side wall (351). In one embodiment, the one or more elastic members (400) may be formed of a soft material and thus may be stretched when the AF housing (340) moves in the optical axis direction. The one or more elastic members (400) may be restored through an elastic restoring force as the AF housing (340) returns to its original position relative to the lower housing (350). Therefore, the deformation of the one or more elastic members (400) may be reversible.
[0074] In one embodiment, one or more elastic members (400) can dampen vibration of the AF housing (340) due to external impact, etc., on the camera module (300). In one embodiment, one or more elastic members (400) can fill a gap between the first side wall (341) of the AF housing (340) and the third side wall (351) of the lower housing (350). Therefore, when an external impact is applied to the camera module (300), the phenomenon of the AF housing (340) vibrating in the X-axis direction or the Y-axis direction of FIG. 6 relative to the lower housing (350) can be alleviated. In one embodiment, when one or more elastic members (400) are disposed between the first side wall (341) and the third side wall (351) as illustrated in FIG. 12b, which will be described later, the rate at which the amplitude of vibration generated in the AF housing (340) is attenuated can increase compared to when one or more elastic members (400) are not disposed between the first side wall (341) and the third side wall (351) as illustrated in FIG. 13a. Accordingly, when vibration occurs in the AF housing (340), the lens assembly (310) accommodated in the AF housing (340) also vibrates, thereby alleviating the image shaking phenomenon that occurs.
[0075] In one embodiment, the one or more elastic members (400) may be formed of various materials. The materials may have a stiffness of from about 1 MPa to about 10 GPa. In one embodiment, a material having a stiffness of from about 10 MPa to 1 GPa may be used. In one embodiment, the one or more elastic members (400) may be formed of a liquid material (e.g., epoxy, polyurethane, silicone) and applied between the first side wall (341) of the AF housing (340) and the third side wall (351) of the lower housing (350). In one embodiment, the one or more elastic members (400) may be formed by applying the liquid material between the first side wall (341) and the third side wall (351) through a dispenser (e.g., an injector) and then curing the liquid material. In one embodiment, one or more elastic members (400) can be converted into a fluid, solid, or semi-solid state through a curing process. In one embodiment, one or more elastic members (400) in a liquid state can be cured through UV curing or thermal curing. In addition, one or more elastic members (400) can be formed into a solid state and bonded to the first side wall (341) of the AF housing (340) and the third side wall (351) of the lower housing (350) through an adhesive member (e.g., double-sided tape, bond).
[0076] FIGS. 7A, 7B, and 7C are drawings illustrating a coupling relationship between an AF housing and a lower housing and a position where an elastic member is arranged, according to one embodiment of the present disclosure.
[0077] According to one embodiment, as illustrated in FIGS. 7A and 7B , the AF housing (340) may be disposed in the lower housing (350) such that the first sidewall (341) and the third sidewall (351) of the lower housing (350) face each other. In one embodiment, the first sidewall (341) of the AF housing (340) may include a first region (341a) of the first sidewall (341) and a second region (341b) of the first sidewall (341). In one embodiment, the first region (341a) of the first sidewall (341) may be substantially perpendicular to the second region (341b) of the first sidewall (341). The third side wall (351) of the lower housing (350) may include a first region (351a) of the third side wall (351) facing the first region (341a) of the first side wall (341) and a second region (351b) of the third side wall (351) facing the second region (341b) of the first side wall (341). The first region (351a) of the third side wall (351) may be substantially perpendicular to the second region (351b) of the third side wall (351).
[0078] According to one embodiment, at least one or more elastic members (400) may be disposed in a space between a first side wall (341) of the AF housing (340) and a third side wall (351) of the lower housing (350), as illustrated in FIGS. 7A and 7B . In one embodiment, the one or more elastic members (400) may include a first elastic member (401) disposed between a first region (341a) of the first side wall (341) and a first region (351a) of the third side wall (351), and a second elastic member (402) disposed between a second region (341b) of the first side wall (341) and a second region (351b) of the third side wall (351). In one embodiment, the first elastic member (401) and the second elastic member (402) may be separated from each other and bonded to the first side wall (341) of the AF housing (340) and the third side wall (351) of the lower housing (350), as illustrated in FIG. 7B. In some embodiments, the first elastic member (401) and the second elastic member (402) may be formed integrally. In such a case, the first elastic member (401) and the second elastic member (402) may be conceptually distinguished according to their positions between the first side wall (341) and the third side wall (351).
[0079] According to one embodiment, as illustrated in FIG. 7c, the first elastic member (401) may cover one end (e.g., one end (SP21) of the second spring member (SP2) of FIG. 7c) of the second spring member (SP2) disposed on the first support surface (3501) of the lower housing (350) (e.g., the first support surface (3501) of FIG. 9a) when the camera module (300) is viewed from above. In one embodiment, the first elastic member (401) may fix one end (SP21) of the second spring member (SP2) disposed on the first support surface (3501) of the lower housing (350) to the lower housing (350). In one embodiment, the first elastic member (401) may be applied in a liquid state between the first region (341a) of the first side wall (341) and the first region (351a) of the third side wall (351) and may be cured through various curing methods (e.g., UV curing or thermal curing). In this case, one end (SP21) of the second spring member (SP2) disposed on the first support surface (3501) may penetrate the first elastic member (401) and be at least partially disposed inside the first elastic member (401). Accordingly, the second spring member (SP2) may be fixed to the lower housing (350) through the first elastic member (401).
[0080] The description of FIG. 7c described above can be equally applied to a case where, when the camera module (300) is viewed from above, the second elastic member (402) covers a portion of the second spring member (SP2) disposed on the first support surface (3501) of the lower housing (350). For example, the second elastic member (402) can secure one end of the second spring member (SP2) disposed on the first support surface (3501) of the lower housing (350) to the lower housing (350).
[0081] In addition, in the embodiment of FIG. 7c, the arrangement relationship of the first elastic member (401), the second elastic member (402), and the second spring member (SP2) disposed between any one of the plurality of first side walls (341) formed in the AF housing (340) and any one of the plurality of third side walls (351) formed in the lower housing (350) is exemplarily described. The description related to FIG. 7c may be equally applied to the first elastic member (401), the second elastic member (402), and the second spring member (SP2) disposed between the remaining side walls of the plurality of first side walls (341) formed in the AF housing (340) and the remaining side walls of the plurality of third side walls (351) formed in the lower housing (350).
[0082] According to one embodiment of the present disclosure, the first elastic member (401) and the second elastic member (402) may be disposed in a space (gap) between the first side wall (341) of the AF housing (340) and the third side wall (351) of the lower housing (350). When an external impact is applied to the camera module (300), vibration of the AF housing (340) relative to the lower housing (350) in the X-axis direction or the Y-axis direction of FIG. 7C may be buffered by one or more elastic members (400). Therefore, when an external force is applied to the camera module (300), the first elastic member (401) and the second elastic member (402) may dampen vibration of the AF housing (340) and alleviate shaking of the lens assembly (310).
[0083] According to one embodiment of the present disclosure, an elastic member (e.g., the first elastic member (401) and the second elastic member (402) of FIG. 7B) may be in contact with the AF housing (340) and the lower housing (350). The AF housing (340) and the lower housing (350) are separate components and may be connected through the elastic member (400).
[0084] FIGS. 8A, 8B, and 8C are drawings illustrating a coupling relationship between an AF housing and a lower housing and a position where an elastic member is arranged according to one embodiment of the present disclosure.
[0085] The description of FIGS. 8A to 8C below may be a description of the first side wall (341) of the AF housing (340) formed in a different shape from the first side wall (341) of the AF housing (340) described in the embodiment of FIGS. 7A to 7C described above. In the description below, the same content as FIGS. 7A to 7C will be omitted.
[0086] According to one embodiment, as illustrated in FIGS. 8A to 8C, the first side wall (341) of the AF housing (340) may include a protrusion (342) protruding toward the third side wall (351) of the lower housing (350). In one embodiment, the protrusion (342) of the AF housing (340) may be in contact with an elastic member (400) (e.g., the first elastic member (401) and / or the second elastic member (402)) disposed between the first side wall (341) and the third side wall (351).
[0087] According to one embodiment, as illustrated in FIGS. 8A to 8C, the first side wall (341) of the AF housing (340) may include a recess (343) formed adjacent to the protrusion (342). In one embodiment, the recess (343) may be formed in an opposite direction from the third side wall (351). For example, the recess (343) may be formed in a first area (341a) of the first side wall (341) facing the first area (351a) of the third side wall (351) (e.g., the first area (341a) of FIG. 7C) and / or in a second area (341b) of the first side wall (341) facing the second area (351b) of the third side wall (351) (e.g., the second area (341b) of FIG. 7C).
[0088] According to one embodiment, as illustrated in FIGS. 8A to 8C, the first elastic member (401) may be at least partially disposed in a recess (343) formed in a first region (341a) of the first side wall (341) and adhered to the protrusion (342) and the first region (351a) of the third side wall (351). The second elastic member (402) may be at least partially disposed in a recess (343) formed in a second region (341b) of the first side wall (341) and adhered to the protrusion (342) and the second region (351b) of the third side wall (351). Therefore, when an external impact is applied to the camera module (300), vibration of the AF housing (340) relative to the lower housing (350) in the X-axis direction or the Y-axis direction of FIG. 8C may be buffered by one or more elastic members (400). Therefore, when an external force is applied to the camera module (300), the first elastic member (401) and the second elastic member (402) can dampen the vibration of the AF housing (340) and alleviate the shaking phenomenon of the lens assembly (310).
[0089] FIGS. 9A and 9B are drawings illustrating the positional relationship of a spring member and an elastic member arranged in a lower housing according to one embodiment of the present disclosure.
[0090] According to one embodiment, as illustrated in FIGS. 9A and 9B , the bottom surface (3511) of the lower housing (350) may include a first support surface (3501) positioned between the third sidewall (351) of the lower housing (350) and the first sidewall (341) of the AF housing (340), and a second support surface (3502) positioned between the third sidewall (351) and the fourth sidewall (352) of the lower housing (350). In one embodiment, the first support surface (3501) may be formed lower than the second support surface (3502). For example, the first support surface (3501) may be positioned in the -Z direction of FIG. 9B with respect to the second support surface (3502) to form a step with the second support surface (3502). However, in some embodiments, the first support surface (3501) and the second support surface (3502) may be positioned substantially on the same plane. Additionally, in some embodiments, the first support surface (3501) may be positioned above the second support surface (3502) to form a step with the second support surface (3502).
[0091] According to one embodiment, as illustrated in FIGS. 9A and 9B , the lower housing (350) may include a third sidewall (351) and a fourth sidewall (352) positioned outwardly relative to the third sidewall (351). In one embodiment, the third sidewall (351) and the fourth sidewall (352) may be formed with different heights (e.g., lengths in the Z-axis direction in FIGS. 9A and 9B ). For example, the height (H1) of the third sidewall (351) with respect to the second support surface (3502) may be formed lower than the height (H2) of the fourth sidewall (352) with respect to the second support surface (3502). In this case, the upper surface of the third sidewall (351) may be positioned lower than the upper surface of the fourth sidewall (352). Conversely, in some embodiments, the height (H1) of the third side wall (351) may be formed higher than the height (H2) of the fourth side wall (352). For example, the height (H1) of the third side wall (351) with respect to the second support surface (3502) may be formed higher than the height (H2) of the fourth side wall (352) with respect to the second support surface (3502). In one embodiment, the height (H1) of the third side wall (351) with respect to the second support surface (3502) may be the same with a constant length. Similarly, the height (H2) of the fourth side wall (352) with respect to the second support surface (3502) may be the same with a constant length. In one embodiment, the fourth side wall (352) may be formed with a length (L2) that surrounds the third side wall (351). For example, the length (L1) in the extension direction of the third side wall (351) (e.g., the length in the direction extending from the first region (351a) to the second region (351b) of the third side wall (351)) may be shorter than the length (L2) in the extension direction of the fourth side wall (352).
[0092] According to one embodiment, as illustrated in FIGS. 9A and 9B , the second spring member (SP2) may be disposed at least partially on the first support surface (3501) and the second support surface (3502) of the lower housing (350), respectively. In one embodiment, the second spring member (SP2) may be partially connected to the AF housing (340), and one end (SP21) (e.g., one end (SP21) of FIG. 7C ) may be disposed on the first support surface (3501) between the first side wall (341) and the third side wall (351) to be adjacent to the elastic member (400) (e.g., the first elastic member (401) and / or the second elastic member (402)). For example, one end (SP21) of the second spring member (SP2) (e.g., one end (SP21) of FIG. 7c) may overlap the first elastic member (401) or the second elastic member (402) when the camera module (300) is viewed from above (e.g., in the -Z direction of FIG. 9b). In one embodiment, one end (SP21) of the second spring member (SP2) (e.g., one end (SP21) of FIG. 7c) may be fixed to the first support surface (3501) of the lower housing (350) or a portion of the lower housing (350) (e.g., the third bulkhead (351)) via the first elastic member (401) and / or the second elastic member (402). In one embodiment, referring to FIGS. 9A and 9B, a portion (SP22) of the second spring member (SP2) may be disposed on a second support surface (3501) of the lower housing (350).
[0093] FIGS. 10A, 10B, 10C and 10D are drawings illustrating the deformability of the arrangement area of the elastic member according to the shape of the spring member, according to one embodiment of the present disclosure.
[0094] According to one embodiment, as illustrated in FIGS. 10A to 10D , at least a portion of the second spring member (SP2) may be disposed on the first support surface (3501) (e.g., the first support surface (3501) of FIG. 9A ) and the second support surface (3502) (e.g., the second support surface (3502) of FIG. 9A ) of the lower housing (350), respectively. In one embodiment, one end (SP21) of the second spring member (SP2) may be disposed on the first support surface (3501) located between the first side wall (341) of the AF housing (340) and the third side wall (351) of the lower housing (350). In one embodiment, one end (SP21) of the second spring member (SP2) may overlap one or more elastic members (400) when the camera module (300) is viewed from above (e.g., in the -Z direction of FIG. 9B described above). In one embodiment, one or more elastic members (400) can secure one end (SP21) of the second spring member (SP2) to the first support surface (3501) of the lower housing (350) or a portion of the lower housing (350) (e.g., the third bulkhead (351)). In one embodiment, referring to FIGS. 10A to 10D , one or more elastic members (400) can be applied along the shape of one end (SP21) of the second spring member (SP2). For example, when sequentially checking FIGS. 10A to 10D , as the shape of one end (SP21) of the second spring member (SP2) expands, an area where one or more elastic members (400) are applied between the first sidewall (341) of the AF housing (340) and the third sidewall (351) of the lower housing (350) can increase. Accordingly, one or more elastic members (400) can have their application area changed based on the extent of expansion of one end (SP21) of the second spring member (SP2).
[0095] FIGS. 11A and 11B are drawings illustrating a camera module including an AF magnet and an AF coil having a different arrangement relationship from the AF magnet and AF coil of FIG. 4.
[0096] The description of FIGS. 11a and 10b below may be a description of a camera module (600) (e.g., the camera module (180) of FIG. 1) including an AF magnet (510) and an AF coil (520) having a different arrangement relationship from the AF magnet (510) and the AF coil (520) of the camera module (300) described through FIGS. 3a to 9b described above. In the description below, descriptions of configurations identical or similar to the configurations described above will be omitted, and may be replaced with the contents described through FIGS. 3a to 9b described above.
[0097] According to one embodiment, as illustrated in FIGS. 11A and 11B , a camera module (600) (e.g., the camera module (180) of FIG. 1 and / or the camera module (300) of FIG. 3A ) may be disposed in an AF housing (340) and include AF magnets (610) (e.g., the AF magnets (510) of FIG. 4 ) that face each other and AF coils (620) (e.g., the AF coils (520) of FIG. 4 ) that face the AF magnets (610). In one embodiment, the AF coils (620) may be disposed in the AF housing (340) and may face each other. In one embodiment, the AF coils (620) may be disposed within a shield can (320) that accommodates the AF housing (340) and covers a portion of the lower housing (350).
[0098] According to one embodiment, as illustrated in FIGS. 11A and 11B , the camera module (600) may include one or more elastic members (400) disposed in a space between a first side wall (341) of the AF housing (340) and a third side wall (351) of the lower housing (350). In one embodiment, the one or more elastic members (400) may include a first elastic member (401) bonded between a first region (341a) of the first side wall (341) and a first region (351a) of the third side wall (351), and a second elastic member (402) bonded between a second region (341b) of the first side wall (341) and a second region (351b) of the third side wall (351), as illustrated in FIGS. 7A to 8C . In one embodiment, the first elastic member (401) and the second elastic member (402) may be physically separated. In some embodiments, the first elastic member (401) and the second elastic member (402) may be formed integrally. Accordingly, when an external impact is applied to the camera module (300), the shaking of the AF housing (340) may be buffered by the elastic member (400) as one or more elastic members (e.g., the first elastic member (401) and / or the second elastic member (402)) are disposed between the first side wall (341) of the AF housing (340) and the third side wall (351) of the lower housing (350).
[0099] FIGS. 12A and 12B are drawings illustrating a camera module including an elastic member positioned at a different location from the elastic member illustrated in FIG. 6 within the camera module, according to one embodiment of the present disclosure.
[0100] The camera module (700) illustrated in FIGS. 12a and 12b below (e.g., the camera module (180) of FIG. 1 and / or the camera module (300) of FIG. 3a) may include the AF magnets (610) and AF coils (620) of the camera module (600) illustrated in FIGS. 11a and 11b.
[0101] The elastic member (800) illustrated in FIGS. 12A and 12B below (e.g., the elastic member (400) of FIG. 6) may be positioned in a region different from one or more of the elastic members (400) described through FIGS. 3A to 11B in the region between the AF housing (340) and the lower housing (350). In the following description, descriptions of configurations identical or similar to the configurations described above will be omitted, and may be replaced with the contents described through FIGS. 3A to 11B above.
[0102] According to one embodiment, as illustrated in FIGS. 12A and 12B, the elastic member (800) may be disposed in a space between a portion of the AF housing (340) where the AF coils (520) are not disposed and the lower housing (350). In one embodiment, the portion where the AF coils (620) are not disposed may be a portion that is substantially perpendicular to the portion where the AF coils (620) are disposed. In one embodiment, the lower housing (350) may include a fifth side wall (353) that faces the portion of the AF housing (340) where the AF coils (620) are not disposed. In one embodiment, the fifth side wall (353) may be formed to extend in a direction that is substantially perpendicular to the bottom surface (3511) of the lower housing (350) (e.g., the +Z direction in FIG. 12A). In one embodiment, a plurality of fifth side walls (353) may be formed to face each other.
[0103] According to one embodiment, as illustrated in FIGS. 12A and 12B, the elastic member (800) may be bonded to the AF housing (340) and the fifth side wall (353) in the space between the portion of the AF housing (340) where the AF coils (520) are not arranged and the fifth side wall (353). In one embodiment, the elastic member (800) may dampen vibration of the AF housing (340) due to external impact, etc., to the camera module (300). For example, when an external impact is applied to the camera module (300), the shaking of the AF housing (340) relative to the lower housing (350) may be cushioned by the elastic member (800) being arranged between the AF housing (340) and the fifth side wall (353). Therefore, when an external force is applied to the camera module (700), the elastic member (800) can dampen the vibration of the AF housing (340) and alleviate the shaking phenomenon of the lens assembly (310).
[0104] FIG. 13a is a graph showing the vibration applied to the AF housing over time when an external impact is applied to a camera module that does not include an elastic member, in a comparative example. FIG. 13b is a graph showing the vibration applied to the AF housing over time when an external impact is applied to a camera module that includes an elastic member of the present disclosure.
[0105] FIG. 13a below is a graph (701) showing the amplitude (μm, micrometer) of vibration applied to the AF housing (340) versus time (ms, millisecond) when no elastic member (400) is placed between the first side wall (341) and the third side wall (351) according to an exemplary simulation. FIG. 13b is a graph (702) showing the amplitude (μm, micrometer) of vibration applied to the AF housing (340) versus time (ms, millisecond) when one or more elastic members (400) are placed between the AF housing (340) and the lower housing (350) illustrated in FIGS. 7a to 8c. This is according to an exemplary simulation.
[0106] In one embodiment, when one or more elastic members (400) are disposed between the first side wall (341) and the third side wall (351), the speed at which vibration occurring in the AF housing (340) is damped may increase compared to when the elastic members (400) are not disposed between the first side wall (341) and the third side wall (351). For example, referring to the graphs (701, 702) of FIGS. 13A and 13B at each time point (t1 to t7), it can be confirmed that the amplitude of vibration of the AF housing (340) according to time shown in the graph (702) of FIG. 13B is lower than the amplitude of vibration of the AF housing (340) according to time shown in the graph (701) of FIG. 13A. In addition, it can be confirmed that the time at which the amplitude of vibration is reduced is faster in the graph (702) of FIG. 13B than in the graph (701) of FIG. 13A. Accordingly, when one or more elastic members (400) are placed between the first side wall (341) of the AF housing (340) and the third side wall (351) of the lower housing (350), vibrations occurring in the AF housing (340) can be attenuated. In addition, when vibrations occur in the AF housing (340), the lens assembly (310) accommodated in the AF housing (340) also vibrates, so that the resulting image shaking phenomenon can be alleviated.
[0107] According to one embodiment, the camera module (180, 300) may include an AF housing (340) used for an AF (auto focus) function that automatically adjusts the focus of the lens (312) on a subject. The AF housing (340) may accommodate a lens assembly (310) including at least one lens (312). The focus of the lens (312) may be adjusted as the AF housing (340) moves in the optical axis direction of the lens (312) (e.g., the Z-axis direction of FIG. 4 described above). The AF housing (340) may be disposed in a lower housing (350) disposed below the AF housing (340) and may move in the optical axis direction of the lens (312) with respect to the lower housing (350). For example, the AF housing (340) can move in the optical axis direction of the lens (312) with respect to the lower housing (350) through an electromagnetic force generated from an AF actuator (e.g., an AF magnet (510, 610) and an AF coil (520, 620)). A certain gap can be formed between the AF housing (340) and the lower housing (350) to facilitate movement of the AF housing (340) in the optical axis direction and to take into account the assembly tolerance of the AF housing (340) with respect to the lower housing (350).
[0108] Meanwhile, when an external impact is applied to the electronic device (101) in which the camera module (180, 300) is disposed, the AF housing (340) may shake relative to the lower housing (350). In this case, the lens assembly (310) disposed in the AF housing (340) may shake together with the AF housing (340). Accordingly, a shaking phenomenon may occur in the image of the subject being photographed by the camera module (180, 300).
[0109] Therefore, including one or more elastic members (400) can contribute to improving image quality because the shaking of the AF housing (340) can be alleviated by the damping of the one or more elastic members (400).
[0110] The technical tasks to be achieved in this document are not limited to the technical tasks mentioned above, and other technical tasks not mentioned can be clearly understood by a person having ordinary knowledge in the technical field to which this document belongs from the description below.
[0111] According to one embodiment of the present disclosure, a camera module (180, 300) may include a lens assembly (310) including one or more lenses (312) substantially aligned along an optical axis, an image sensor (381) configured to detect light acquired through the lens assembly, an auto focus (AF) housing (340) having a first sidewall (341) and configured to at least partially accommodate the lens assembly and move substantially along the optical axis, an upper housing (330) including a second sidewall (331) at least partially surrounding the AF housing and facing the first sidewall and spaced apart from the first sidewall, a lower housing (350) coupled to the upper housing, including a third sidewall (351) at least partially surrounding the image sensor and positioned between the first sidewall and the second sidewall, and an elastic member (400) disposed between the third sidewall of the lower housing and the first sidewall of the AF housing.
[0112] In one embodiment, the lower housing further comprises a spring member (SP2), one ending portion of the spring member being connected to the AF housing and another ending portion of the spring member being extending between the first side wall and the third side wall and positioned adjacent to the elastic member.
[0113] In one embodiment, at least a portion of the other ending portion of the spring member may be arranged to penetrate the elastic member.
[0114] In one embodiment, the third side wall may be formed to substantially face an edge of the AF housing.
[0115] In one embodiment, the third side wall comprises a first region (351a) and a second region (351b) that are substantially perpendicular to each other, and the elastic member may comprise a first elastic member (401) and a second elastic member (402) disposed in the first region and the second region, respectively.
[0116] In one embodiment, the first elastic member and the second elastic member may be spaced apart from each other.
[0117] In one embodiment, the first side wall may include a protrusion (342) protruding toward the third side wall to contact the elastic member.
[0118] In one embodiment, the protrusion includes a recess (343) formed in an opposite direction from the third side wall at one end, and at least a portion of the recess can contact the elastic member.
[0119] In one embodiment, a portion of the second side wall may protrude toward the lower housing so as to cover at least a portion of the elastic member when viewed from above the camera module.
[0120] In one embodiment, the lower housing may include a fourth side wall (352) disposed outside the second side wall of the upper housing.
[0121] In one embodiment, one end of the second sidewall of the upper housing may be positioned between the third sidewall and the fourth sidewall of the lower housing.
[0122] In one embodiment, the height (H1) of the third side wall may be formed lower than the height (H2) of the fourth side wall.
[0123] In one embodiment, the length (L1) of the third side wall may be shorter than the length (L2) of the fourth side wall.
[0124] In one embodiment, the third side wall and the fourth side wall protrude from the bottom surface (3511) of the lower housing, and the bottom surface includes a first support surface (3501) between the third side wall and the first side wall and a second support surface (3502) between the third side wall and the fourth side wall, and the first support surface can be formed lower than the second support surface.
[0125] In one embodiment, the camera module has a height (H1) of the third side wall that is substantially the same throughout its length.
[0126] In one embodiment, no elastic member may be disposed between the second side wall and the third side wall.

Absence (400) may be included.
[0128] In one embodiment, the lower housing further comprises a spring member (SP2), one ending portion of the spring member being connected to the AF housing and another ending portion of the spring member being extending between the first side wall and the third side wall and positioned adjacent to the elastic member.
[0129] In one embodiment, the third side wall is formed to substantially face the edges of the AF housing and includes a first region (351a) and a second region (351b) that are substantially perpendicular to each other, and the elastic member may include a first elastic member (401) and a second elastic member (402) that are respectively (respectively) disposed in the first region and the second region.
[0130] In one embodiment, a portion of the second side wall may protrude toward the lower housing so as to cover at least a portion of the spring member when viewed from above of the camera module.
[0131] According to various embodiments disclosed in this document, an elastic member (400) may be disposed between one side wall (341) of the AF housing (340) and one side wall (351) of the lower housing (350). The elastic member (400) may dampen vibration (e.g., shaking) of the AF housing (340) relative to the lower housing (350) when an external impact is applied to the camera module (180, 300). Accordingly, when vibration occurs in the AF housing (340), the lens assembly (310) accommodated in the AF housing (340) also vibrates, thereby alleviating the image shaking phenomenon that occurs.
[0132] In a comparative example, when the AF housing (340), the lower housing (350), and the upper housing (330) are assembled, an elastic member (400) may be applied between one side wall (341) of the AF housing (340) and one side wall (351) of the lower housing (350). In this case, the elastic member (400) may be applied to an unintended location (e.g., an area other than between one side wall (341) of the AF housing (340) and one side wall (351) of the lower housing (350), and the elastic member (400) may be contaminated by foreign substances. According to one embodiment of the present disclosure, after the elastic member (400) is applied between one side wall (341) of the AF housing (340) and one side wall (351) of the lower housing (350), the upper housing (330) may be assembled to the lower housing (350). Accordingly, the elastic member (400) can be accurately applied to one side wall (341) of the AF housing (340) and one side wall (351) of the lower housing (350), and the possibility of contamination of the elastic member (400) by foreign substances can be reduced.
