[0061] Hereinafter, embodiments of the present application capable of achieving the above object will be described with reference to the accompanying drawings.

[0062] In the following description of the embodiments, it will be understood that, when a component is referred to as being "formed on" or "under" another component, the component can be directly on or under the other component, or can be indirectly disposed with one or more intermediate components therebetween. In addition, it will also be understood that "on" or "under" can indicate a direction upward or downward based on the component.

[0063] In addition, relative terms such as "first", "second", "upper / upper portion / upper side" and "lower / lower portion / lower side" used in the following description can be used to distinguish any one substance or component from another substance or component, without implying or implying any physical or logical relationship or order between the substances or components. In all the drawings, the same reference numerals represent the same elements.

[0064] Unless otherwise defined, the terms "comprise", "include" or "have" used in the above description are used to specify the presence of features, steps or combinations thereof described in the specification, and it should be understood that one or more different features, steps or combinations thereof are not excluded or possible.

[0065] In addition, when describing the components of the present disclosure, terms such as "first", "second", "A", "B", "(a)" or "(b)" can be used. Since these terms are provided only to distinguish the components from other components, these terms do not limit the nature, sequence or order of the components. If a component is described as being "joined", "coupled" or "connected" to another component, it should be understood that, although the component can be directly joined, coupled or connected to the other component, the component and the other component can also be indirectly "joined", "coupled" or "connected" via another component.

[0066] Hereinafter, a lens moving apparatus according to an embodiment of the disclosure will be described with reference to the accompanying drawings. For convenience of description, although a right-angled coordinate system (x, y, z) is used to describe the lens moving apparatus, the lens moving apparatus can be described using some other coordinate system, and the embodiments are not limited thereto. In the respective drawings, the X-axis and the Y-axis refer to directions perpendicular to the optical axis, i.e., the Z-axis, and the optical axis OA direction or a direction parallel to the optical axis OA can be referred to as a "first direction", the X-axis direction can be referred to as a "second direction", and the Y-axis direction can be referred to as a "third direction".

[0067] The term "optical axis direction" is defined as the optical axis direction of a lens or a lens module in a state in which the lens or the lens module is coupled to the lens moving apparatus. Here, the term "optical axis direction" can also be used to indicate the up-down direction or the vertical direction.

[0069] Figure 1 is a perspective view of a lens moving apparatus 100 according to an embodiment. Figure 2 is Figure 1 is an exploded view of the lens moving apparatus 100 shown in Figure 3 is shown Figure 1 is the lens moving apparatus 100 shown in

[0070] Referring to Figures 1 to 3 , the lens moving apparatus 100 can include a cover member 300, a bobbin 110, a coil 120, a magnet 130, an upper elastic member 150, a lower elastic member 160, and a base 210.

[0071] The cover member 300 will be described first.

[0072] The cover member 300 accommodates the components 110, 120, 130, 140, 150, 160, and 400 in a space defined between the cover member 300 and the base 210.

[0073] The cover member 300 can take the form of a box having an open bottom and including a top plate and side plates. Lower ends of the side plates of the cover member 300 can be coupled to a top of the base 210. The top plate of the cover member 300 can have a polygonal shape, such as a square or an octagonal shape.

[0074] The cover member 300 can be provided with an opening in an upper plate of the cover member 300 through which the lens unit 400 coupled to the spool 110 is exposed to external light.

[0075] For example, the cover member 300 can be made of a non-magnetic material such as SUS, aluminum (Al), copper (Cu), tin (Sn), or platinum. Because the cover member 300 made of a non-magnetic material is used, this embodiment can prevent the phenomenon in which the magnet 130 attracts the cover member 300. In another embodiment, the cover member 300 can be made of a magnetic material or a plastic material.

[0076] An adhesive injection recess 305 can be provided in a lower end portion of at least one of the side plates of the cover member 300.

[0077] A groove 306 through which the first and second connection terminals 164a and 164b of the lower springs 160a and 160b are exposed can be formed in a lower end portion of one of the side plates of the cover member 300.

[0078] Next, the spool 110 will be described.

[0079] Figure 4a is Figure 2 a perspective view of the spool 110. Figure 4b is Figure 4a a perspective view of the spool 110 and the coil.

[0080] Referring to Figure 4a and Figure 4b , the spool 110 can be positioned inside the posts 216a to 216d of the base 210 and can move in a first direction (for example, in the Z-axis direction) by electromagnetic interaction between the coil 120 and the magnet 130.

[0081] For example, the spool 110 can move in two directions, for example, in an upward direction (+Z-axis direction) or a downward direction (-Z-axis direction), from an initial position of the spool 110. In another embodiment, the spool 110 can move in one direction, for example, in an upward direction, from an initial position of the spool 110.

[0082] The spool 110 can have an opening in which a lens or a lens barrel is mounted.

[0083] The shape of the opening in the spool 110 can correspond to the shape of the lens and the lens barrel mounted in the spool. For example, the shape of the opening can be circular, elliptical, or polygonal. However, the present disclosure is not limited thereto.

[0084] The bobbin 110 can include at least one first coupling portion 113 located at an upper surface of the bobbin 110 and coupled and fixed to the inner frame 151 of the upper elastic member 150, and at least one second coupling portion 117 located at a lower surface of the bobbin 110 and coupled and fixed to the inner frame 161 of the lower elastic member 160.

[0085] Although the first coupling portion 113 of the bobbin 110 can have, for example, a flat surface, the present disclosure is not limited thereto. In another embodiment, the first coupling portion 113 can have the form of a protrusion or a groove. Although the second coupling portion 117 of the bobbin 110 can have the form of a protrusion, the present disclosure is not limited thereto. In another embodiment, the second coupling portion can have the form of a groove or a flat surface.

[0086] The bobbin 110 can have an upper avoidance recess 112a provided in a region of an upper surface of the bobbin 110 corresponding to or aligned with the first frame connection portion 153 of the upper elastic member 150.

[0087] Further, the bobbin 110 can have a lower avoidance recess 112b provided in a region of a lower surface of the bobbin 110 corresponding to or aligned with the second frame connection portions 163-1 and 163-2 of the lower elastic member 160.

[0088] When the bobbin 110 moves in the first direction, the space interference between the first frame connection portion 153 and the bobbin 110 and between the second frame connection portions 163-1 and 163-2 and the bobbin 110 can be avoided by the upper avoidance recess 112a and the lower avoidance recess 112b of the bobbin 110, so that the first frame connection portion 153 of the upper elastic member 150 and the second frame connection portions 163-1 and 163-2 of the lower elastic member 160 can be easily elastically deformed.

[0089] The bobbin 110 can be provided with at least one mounting recess 105 in an outer surface 110b thereof, and the coil 120 can be placed or mounted in the mounting recess 105 in the bobbin 110. For example, as shown in FIG. 1B, the mounting recess 105 can have the shape of a ring provided about the optical axis OA; however, the present disclosure is not limited thereto. Figure 4a The shape and number of the mounting recess 105 can correspond to the shape and number of the coil provided about the outer surface 110b of the bobbin 110. In another embodiment, the bobbin 110 can not have a recess for mounting the coil.

[0090] The shape and number of the mounting recess 105 can correspond to the shape and number of the coil provided about the outer surface 110b of the bobbin 110. In another embodiment, the bobbin 110 can not have a recess for mounting the coil.

[0091] The bobbin 110 can include a first outer portion 110b-1 corresponding to the columns 216a to 216d of the base 210 and a second outer portion 110b-2 corresponding to an area between the columns 216a to 216d.

[0092] Next, the coil 120 will be described.

[0093] The coil 120 is disposed around the outer portion and the outer surface of the bobbin 110 and electromagnetically interacts with the magnets 130 disposed at the base 210.

[0094] In order to generate an electromagnetic force due to the electromagnetic interaction with the magnets 130, a driving signal can be applied to the coil 120. At this time, the driving signal can be a direct current signal, or can be in the form of a voltage or a current.

[0095] An auto focus (AF) operation unit elastically supported by the upper elastic member 159 and the lower elastic member 160 by means of the electromagnetic interaction between the coil 120 and the magnets 130 can move in a first direction. By controlling the electromagnetic force, the movement of the bobbin 110 in the first direction can be controlled, thereby performing an auto focus function.

[0096] The AF operation unit can include the bobbin 110 elastically supported by the upper elastic member 150 and the lower elastic member 160 and a component mounted on the bobbin 110 and moving together with the bobbin. For example, the AF operation unit can include the bobbin 110 and the coil 120.

[0097] Referring to Figure 4b , the coil 120 can be wound or disposed around the outer peripheral surface of the bobbin 110 in a clockwise or counterclockwise direction around the optical axis OA.

[0098] For example, the coil 120 can be disposed or wound in the mounting recess 105 disposed in the outer surface of the bobbin 110.

[0099] For example, the coil 120 can have a shape of a ring surrounding the outer surface of the bobbin 110 in a clockwise direction or a counterclockwise direction around the optical axis OA. In Figure 4b , the coil 120 can have a shape of a single ring; however, the disclosure is not limited thereto.

[0100] In another embodiment, the coil 120 can be implemented as a coil ring wound in a clockwise or counterclockwise direction around an axis perpendicular to the optical axis OA. Although the number of coil rings can be equal to the number of magnets 130, the disclosure is not limited thereto.

[0101] The coil 120 may be electrically connected to at least one of the upper elastic member 150 or the lower elastic member 160. For example, the coil 120 may be electrically connected to the lower springs 160a and 160b, and a drive signal may be applied to the coil 120 through the lower springs 160a and 160b.

[0102] Next, the base 210 will be described.

[0103] Figure 5a yes Figure 2 The first perspective view of the base 210 shown. Figure 5b yes Figure 2 The second perspective view of the base 210 shown. Figure 5c yes Figure 2 The third perspective view of the base 210 shown. Figure 6 yes Figure 2 The perspective view of the lower elastic member 160 shown. Figure 7 Magnets 130-1 and 130-2 connected to the base 210 and the lower elastic member 160 are shown. Figure 8 The upper elastic member 150 connected to the base 210 is shown. Figure 9 This is an exploded perspective view of the base 210 and the magnet 130. Figure 10 This is a three-dimensional view of the assembly of the base 210 and the magnet 130. Figure 11 This is an exploded enlarged view of the base 210, in which the lower elastic member 160 is connected to the base 210. Figure 12 yes Figure 3 The cross-sectional view of the lens moving device shown is taken along the AB direction.

[0104] Reference Figures 5a to 5c The base 210 can be connected to the cover member 300 and can cooperate with the cover member 300 to define a space for accommodating the spool 110.

[0105] The base 210 may have an opening corresponding to the opening in the cover member and / or the opening in the spool 110. The base 210 may have a shape that coincides with or corresponds to the cover member 300, such as a square shape.

[0106] The base 210 may include a body 213 with an opening and posts 216a to 216d protruding from the body 213.

[0107] The body 213 may include corner portions 217a to 217d and side portions 218a to 218d located between the corner portions 217a to 217d.

[0108] Each of the columns 216a to 216d can be located at a corresponding corner of the corner portions 217a to 217d of the body 213.

[0109] For example, the base 210 can include a first pillar 216a, a second pillar 216b, a third pillar 216c, and a fourth pillar 216d protruding upward from a first corner portion 217a to a fourth corner portion 217d by a predetermined height.

[0110] The term "pillar" of the base 210 can be used interchangeably with the term "protrusion".

[0111] Although each of the pillars 216a to 216d can have a polygonal shape protruding vertically from an upper surface of the body 213 of the base 210, for example, the present disclosure is not limited thereto. Although the pillars 216a to 216d can have a cross-section of, for example, an "L" shape or a polygonal shape, the present disclosure is not limited thereto.

[0112] The body 213 of the base 210 can include an upper surface and an outer lateral surface, and can include a first surface positioned inside the first pillar 216a to the fourth pillar 216d around the opening and a second surface positioned outside the first surface and higher than the first surface.

[0113] For example, the first surface of the upper surface of the body 213 of the base 210 can be a surface serving as a reference surface for a protrusion height of the pillars 216a to 216d or a height of the first step portion 25a.

[0114] For example, the second surface of the body 213 of the base 210 can be an upper surface of the protrusion 25c, and the lower elastic member 160 can be coupled to the second surface of the upper surface of the body 213.

[0115] Each of the lateral portion 218a to 218d of the body 213 of the base 210 can be disposed between two adjacent corner portions 217a to 217d among the corner portions 217a to 217d.

[0116] Although a length of each of the lateral portion 218a to 218d of the body 213 of the base 210 in a transverse direction can be greater than a length of each of the corner portions 217a to 217d of the body 213 of the base 210, the present disclosure is not limited thereto.

[0117] The base 210 can include the opening positioned between two adjacent pillars 216a and 216b, between two adjacent pillars 216b and 216c, between two adjacent pillars 216c and 216d, and between two adjacent pillars 216d and 216a, and on the first step portion 25a and the protrusion 25c.

[0118] The first magnet 130-1 can be disposed between the first and second posts 216a and 216b, and the second magnet 130-2 can be disposed between the third and fourth posts 216c and 216d.

[0119] For example, the first magnet 130-1 can be disposed on the first side portion 218a, and the second magnet 130-2 can be disposed on the third side portion 218c.

[0120] Each of the first and third side portions 210a and 218c of the base 210 can be provided with a first step portion 25a, and each of the posts 216a to 216d of the base 210 can be provided with a second step portion 25b.

[0121] The first and second magnets 130-1 and 130-2 can be disposed at the first and second step portions 25a and 25b. The first and second step portions 25a and 25b can function to support the first and second magnets 130-1 and 130-2 to prevent the first and second magnets 130-1 and 130-2 from being inclined inward.

[0122] The first step portion 25a can have a depth DP1 with respect to an outer surface of the body 213, and the second step portion 25b can have a depth DP2 with respect to an outer surface of the posts 216a to 216d.

[0123] For example, each of the first step portions 25a can include a first surface 25a1 and a second surface 25a2, wherein the first surface 25a1 is a stepped surface having a depth with respect to a corresponding one of the outer surfaces 29a of the side portions 218a and 218c of the body 213, and the second surface 25a2 is disposed between the respective one of the outer surfaces 29a of the side portions 218a and 218c of the body 213 and the first surface 25a1.

[0124] For example, each of the second step portions 25b can include a first surface 25b1 and a second surface 25b2, wherein the first surface 25b1 is a stepped surface having a depth with respect to a respective one of the outer surfaces 92b of the posts 216a to 216d, and the second surface 25b2 is positioned between the respective one of the outer surfaces 92b of the posts 216a to 216d and the first surface 25b1.

[0125] For example, the base 210 can include first stepped portions 25a each having a depth DP1 with respect to a first outer surface of the body 213 (e.g., an outer surface of the first side portion 218a of the body 213) and positioned between the first and second posts 216a and 216b. For example, the outer surface of the body 213 can be an outer surface of a side portion provided with the first magnet 130-1 between outer surfaces of the body 213.

[0126] For example, each of the first and second posts 216a and 216b can include second stepped portions 25b having a depth DP2 with respect to a first outer surface 92b of each of the first and second posts 216a and 216b. For example, the outer surface 92b of each of the first and second posts 216a and 216b can be an outer surface contiguous with the first side portion 218a of the body 213 between outer surfaces of the first and second posts 216a and 216b.

[0127] Further, the base 210 can include third stepped portions having a depth with respect to a second outer surface of the body 213 (e.g., an outer surface of the third side portion 218c of the body 213) and positioned between the third and fourth posts 216c and 216d.

[0128] Each of the third and fourth posts 216c and 216d can include fourth stepped portions having a depth with respect to a first outer surface of each of the third and fourth posts 216c and 216d. For example, the outer surface of each of the third and fourth posts 216c and 216d can be an outer surface contiguous with the third side portion 218c of the body 213.

[0129] For example, the first magnet 130-1 can be provided at the first and second stepped portions 25a and 25b, and a surface of the first magnet 130-1 can be in contact with a first surface 25a1 of the first stepped portion 25a and a first surface 25b1 of the second stepped portion 25b.

[0130] For example, the second magnet 130-2 can be provided at the third and fourth stepped portions, and a surface of the second magnet 130-2 can be in contact with a first surface of the third stepped portion and a first surface of the fourth stepped portion.

[0131] For example, the first depth DP1 can be equal to the second depth DP2. To mount the first magnet 130-1 and the second magnet 130-2, the first depth DP1 and the second depth DP2 can be equal to or greater than a length of each of the first magnet 130-1 and the second magnet 130-2. Here, the length of each of the first magnet and the second magnet can be a length of each of the first depth DP1 and the second depth DP2 in the step direction.

[0132] The first surface 25a1 of the first stepped portion 25a and the first surface 25b1 of the second stepped portion 25b can prevent the adhesive member 75 (see Figure 15 ) from flowing toward the bobbin 110 of the lens moving device 100, which is injected through the adhesive injection recesses 47a and 47b in order to attach the first magnet 130-1 and the second magnet 130-2 to the base 210.

[0133] The term "first protrusion (or first stepped portion)" can be used to refer to the first stepped portion 25a, and the term "second protrusion (or second stepped portion)" can be used to refer to the second stepped portion 25b.

[0134] For example, the "first protrusion" can be positioned between the first post 216a and the second post 216b and between the third post 216c and the fourth post 216d, and can vertically protrude from the upper surface of the side portion of the body. For example, the vertical direction can be a direction from the lower surface of the base 210 (e.g., the lower surface of the body 213) toward the upper surface of the base 210 (e.g., the upper surface of the body 213).

[0135] The "second protrusion" can protrude in a first horizontal direction from the side surface of each of the posts 216a to 216d. For example, the first horizontal direction can be a direction from each of the posts 216a to 216d toward the first magnet 130-1 or the second magnet 130-2.

[0136] Although the first height of the first protrusion with respect to the side surface 92a of each of the posts 216a to 216d can be equal to the second height of the second protrusion with respect to the side surface 92a of each of the posts 216a to 216d, the present disclosure is not limited thereto. In another embodiment, the first height can be greater than the second height. In another embodiment, the first height can be less than the second height. The side surface 92a of each of the posts 216a to 216d can be the second surface 25b2 of the second stepped portion 25b.

[0137] The first length or thickness D1 of the first protrusion in the direction of the first depth DP1 may be less than the first depth DP1. The thickness D1 of the first protrusion may be different from the length or thickness D2 of the second protrusion in the direction of the second depth DP2. For example, D1 may be less than D2.

[0138] The thickness D2 of the second protrusion can gradually decrease along the protruding direction of the second protrusion. This is done to avoid spatial interference between the bobbin 110 and the posts 216a to 216d of the base 210 during the movement of the bobbin 110.

[0139] For example, the side surface 92a of the column (e.g., 216a and 216b, 216c and 216d) can be the side surface of two adjacent columns (e.g., 216a and 216b, 216c and 216d) facing each other.

[0140] The side surface 92b of each of the columns 216a to 216d can be one of the outer surfaces of the column, and can be a side surface that is perpendicular to the side surface 92a of each of the columns 216a to 216d and parallel to the outer surface of the first side portion or the third side portion of the base 210.

[0141] For example, the first protrusion may abut against the side surfaces of the first post 216a and the second post 216b, and may abut against the side surfaces 92a of the third post and the fourth post. However, this disclosure is not limited thereto. In another embodiment, the first protrusion may be spaced apart from the side surfaces 92a of two adjacent posts.

[0142] Although the first protrusion may be adjacent to the second protrusion, this disclosure is not limited thereto. In another embodiment, the first protrusion and the second protrusion may be spaced apart from each other.

[0143] Despite Figures 5a to 5c A first protrusion is shown as being disposed at each of the first side portion 218a and the third side portion 218c of the base 210, and a second protrusion is shown as being disposed at each of the side surfaces 92a of each of the pillars 216a to 216d, but the present disclosure is not limited thereto.

[0144] In another embodiment, two or more first protrusions spaced apart from each other may be provided at each of the first side portion 218a and the third side portion 218c of the base 210, and two or more second protrusions spaced apart from each other may be provided at the side surface 92a of each of the posts 218a to 218d.

[0145] Based on the upper surface of the body 213 of the base 210, the height of the pillars 216a to 216d can be greater than the height of the first protrusion.

[0146] Each of the second side portion 218b and the fourth side portion 218d of the body 213 of the base 210 can be provided with a protrusion 25c protruding in a vertical direction or an optical axis direction from the upper surface of the body 213 of the base 210. The protrusion 25c can protrude from the upper surface around the opening in the body 213.

[0147] For example, the protrusion 25c can be positioned between the second post 216b and the third post 216c, and can be positioned between the first post 216a and the fourth post 216d. The upper surface of the protrusion 25c can be positioned higher than the upper surface of the body.

[0148] Although the protrusion 25c can be contiguous with the side surfaces of two adjacent posts (e.g., 216a and 216d, 216b and 216c), the present disclosure is not limited thereto.

[0149] Each of the posts 216a to 216d can further include a side surface 92d positioned between the second step portion 25b and the side surface 92c. The side surface of each of the posts 216a to 216d can be a surface facing the first side portion 110b-1 of the bobbin 110.

[0150] The surface of the second protrusion can be positioned flush with the side surface 92d of each of the posts 216a to 216d, and the side surface 92d of each of the posts 216a to 216d can be positioned to face the first stopper 23.

[0151] For example, the side surface 92d of each of the posts 216a to 216d can be a surface inclined at a predetermined angle θ1 (see FIG. 10) with respect to or parallel to an imaginary plane or line of the side surface 92b of each of the posts 216a to 216d. Figure 11 ) of the bobbin 110.

[0152] Although the angle θ1 of the side surface 92d of each of the posts 216a to 216d can be, for example, equal to the angle θ2 of the outer surface of the first side portion 110b-1 of the bobbin 110 corresponding to the side surface 92d of each of the posts 216a to 216d, the present disclosure is not limited thereto.

[0153] The angle θ1 of the side surface 92d of each of the posts 216a to 216d can be in the range of 25 degrees to 60 degrees. For example, the angle θ1 of the side surface 92d of each of the posts 216a to 216d can be in the range of 40 degrees to 50 degrees.

[0154] Each of the columns 216a to 216d can further include a side surface 92e positioned between the side surface 92c and the side surface 92d.

[0155] Although the side surface 92e of each of the columns 216a to 216d can be parallel to the side surface 92b of each of the columns 216a to 216d, for example, the present disclosure is not limited thereto.

[0156] For example, each of the columns 216a to 216d can include a bent surface defined by the side surface 92d and the side surface 92e.

[0157] The base 210 can include first stoppers 23 protruding from the upper surface of the body 213. Although the stoppers 23 can be respectively provided at the columns 216a to 216d, the present disclosure is not limited thereto. The first stoppers 23 can also be referred to as "lower stoppers".

[0158] For example, the first stoppers 23 can be provided to respectively correspond to the second frame connection portions 163-1 and 163-2 of the lower elastic members 160.

[0159] In order to avoid spatial interference between the spool 110 and the lower elastic member 160, the first stoppers 23 can be positioned higher than the second frame connection portions 163-1 and 163-2 of the lower springs 160a and 160b coupled to the base 210.

[0160] The first stoppers 23 of the base 210 can prevent the lower surface or the lower end of the spool 210 from directly colliding with the body 213 of the base 210 when an external impact is applied.

[0161] The base 210 can include support protrusions 24 protruding from the upper surface of the body 213.

[0162] Each of the support protrusions 24 can connect the first stepped portion (or the first protrusion) provided between two adjacent side portion of the body 213 to the protrusion 25c.

[0163] For example, each of the support protrusions 24 can connect the inner surface of the first stepped portion (or the first protrusion) 25a to the inner surface of the protrusion 25c.

[0164] Each of the support protrusions 24 can function to support the first stepped portion (or the first protrusion) 25a to the protrusion 25c. Based on the upper surface of the body of the base 210, the height of the support protrusion 24 can be smaller than the height of the first surface 25a1 of the first stepped portion 25a (or the height of the first protrusion) and the height of the protrusion 25c.

[0165] The support protrusion 24 can be positioned between the columns 216a to 216d and the opening in the base 210, and the first stopper 23 can be positioned on the support protrusion 24, respectively.

[0166] To be coupled to the upper elastic member 150, the base 210 can include the first protrusion 22 disposed on at least one upper portion or upper surface of the columns 216a to 216d.

[0167] For example, the base 210 can include at least one first protrusion 22 protruding from the upper surfaces of the columns 216a to 216d.

[0168] The lower elastic member 160 can be coupled to the base 210 between the first column 216a and the fourth column 216d adjacent to the first column 216a.

[0169] In addition, the lower elastic member 160 can be coupled to the base 210 between the second column 216b and the third column 216c adjacent to the second column 216b.

[0170] The lower elastic member 160 can not be coupled to the base 210 between the first column 216a and the second column 216b and between the third column 216c and the fourth column 216d.

[0171] The base 210 can include a protrusion 25c positioned between the first column 216a and the fourth column 216d and between the second column 216b and the third column 216c and protruding from the body 213, and at least one second protrusion 21 disposed on the upper surface of the protrusion 25c.

[0172] Although the number of the second protrusions 21 is two in the present embodiment, the disclosure is not limited thereto. The number of the second protrusions 21 can be one or more.

[0173] For example, two second protrusions 21 can be disposed at the protrusion 25c of the base 210 to be spaced apart from each other, and each of the second protrusions 21 can protrude from the upper surface of the protrusion 25c.

[0174] For example, to avoid spatial interference with the magnets 130-1 and 130-2, the second protrusions 21 can be disposed at the second side portion 218b and the fourth side portion 218d of the body 213 where the magnets 130-1 and 130-2 are not disposed.

[0175] A guide protrusion 27 can be provided on the fourth side portion 218d of the body 213 of the base 210. The guide protrusion 27 can be provided at the protrusion 25c provided at the fourth side portion 218d of the body 213. The guide protrusion 27 can be used to stably fix portions of the second outer frames of the lower springs 160-1 and 160-2 adjacent to the connection terminals 164a and 164b by increasing the contact area with the extension portions 62a and 62b of the second outer frames of the lower springs 160-1 and 160-2.

[0176] For example, the guide protrusion 27 can be provided between the protrusions 21 provided on the protrusion 25c.

[0177] A mounting recess 28 in which the connection terminals 164a and 164b of the lower springs 160a and 160b are disposed can be formed in the outer surface of the fourth side portion 218d of the body 213 of the base 210.

[0178] A stepped portion 211 can be provided at a lower end of the outer surface of the body 213 of the base 210. The stepped portion 211 can be in contact with a lower end of a side plate of the cover member 300 and can guide the cover member 300. The stepped portion 211 of the base 210 and the lower end of the side plate of the cover member 300 can be fixed to each other in an adhesive and sealable manner and can be sealed using an adhesive or the like.

[0179] Next, the lower elastic member 160 and the upper elastic member 150 will be described.

[0180] Referring to Figure 6 and Figure 8 The upper elastic member 150 and the lower elastic member 160 can be coupled to the bobbin 110 and the base 210 and can elastically support the bobbin 110.

[0181] The upper elastic member 150 can be coupled to an upper portion, an upper surface, or an upper end of the bobbin 110 and can be coupled to an upper portion, an upper surface, or an upper end of the columns 216a to 216d of the base 210.

[0182] The lower elastic member 160 can be coupled to a lower portion, a lower surface, or a lower end of the bobbin 110 and can be coupled to the side portions 218b and 218d of the base 210.

[0183] Although each of the upper elastic member 150 and the lower elastic member 160 can be implemented as a leaf spring, the present disclosure is not limited thereto. Each of the upper elastic member 150 and the lower elastic member 160 can be implemented as a coil spring, a suspension wire, or the like.

[0184] The upper elastic member 150 can include a first inner frame 151 coupled to the first coupling portion 113 of the bobbin 110, a first outer frame 152 coupled to the first protrusion 22 of the base 210, and a first frame connecting portion 153 connecting the first inner frame 151 to the first outer frame 152.

[0185] The first outer frame 152 can be disposed on upper surfaces of the columns 216a to 216d and upper surfaces of the first magnet 130-1 and the second magnet 130-2.

[0186] Although the upper elastic member 150 is implemented as a single upper spring in Figure 8 the disclosure is not limited thereto. In another embodiment, the upper elastic member can include a plurality of upper springs spaced apart or separated from each other.

[0187] The first inner frame 151 of the upper elastic member 150 can be provided with a through-hole or a groove 151a so as to be coupled with the first coupling portion 113 of the bobbin 110, and the first outer frame 152 can be provided with a through-hole or a groove so as to facilitate coupling of the first protrusion 22 of the base 210.

[0188] The upper elastic member 150 coupled to the base 210 can be spaced apart from an inner surface of the cover member 300.

[0189] In addition, the first inner frame 151 of the upper elastic member 150 coupled to the bobbin 110 can be inclined or bent lower than the first outer frame 152 fixed to the columns 216a to 216d.

[0190] The lower elastic member can include a first lower spring 160a and a second lower spring 160b positioned on the inner sides of the columns 126a to 126d and spaced apart from each other. The first lower spring 160a and the second lower spring 160b can be spaced apart from each other and can be electrically isolated from each other.

[0191] Each of the first lower spring 160a and the second lower spring 160b can include a second inner frame 161 to be coupled to the second coupling portion 117 of the bobbin 110, a second outer frame 162-1 and 162-2, and a second frame connecting portion 163-1 and 163-2 configured to connect the second inner frame 161 to the second outer frame 162-1 and 162-2.

[0192] For example, the second outer frame 162 can be disposed on upper surfaces of the side portion 218b and 218d and / or the upper surface 25c of the body 213 of the base 210.

[0193] Although each of the first lower spring 160a and the second lower spring 160b can include, for example, a single second inner frame 161, two second outer frames 162-1 and 162-2, and two second frame connecting portions 163-1 and 163-2, the number of the second inner frames, the number of the second outer frames, and the number of the second frame connecting portions are not limited thereto.

[0194] Each of the two outer frames 162-1 and 162-2 can be coupled to a respective one of the second protrusions 21 provided on the protrusion 25c of the base 210.

[0195] For example, the second inner frame 161 of each of the first lower spring 160a and the second lower spring 160b can be provided with a through-hole or a groove so as to be coupled with the second coupling portion 117 of the wire drum 110, and the second outer frames 162-1 and 162-2 can be provided with through-holes or grooves 162a so as to be coupled with the second protrusions 21 of the base 210.

[0196] By means of an adhesive or heat fusion, the first coupling portion 113 and the through-hole 151a in the first inner frame 151 can be bonded to each other, the second coupling portion 117 of the wire drum 110 and the through-hole 161a in the second inner frame 152 can be bonded to each other, the first protrusion 22 of the base 210 and the through-hole 152a in the first outer frame 152 can be bonded to each other, and the second protrusion 21 of the base 210 and the through-holes 162a in the second outer frames 162-1 and 162-2 can be bonded to each other.

[0197] Each of the first frame connecting portion 153 and the second frame connecting portions 163-1 and 163-2 can be bent or curved at least once to define a predetermined pattern.

[0198] By means of a change in position and a slight deformation of the first frame connecting portion 153 and the second frame connecting portions 163, upward and / or downward movement of the wire drum 110 in the first direction can be elastically (or flexibly) supported.

[0199] The second frame connecting portion 163 can be a portion (or a bent portion) that surrounds at least a portion of a side surface of the first stopper 23.

[0200] Although the portion surrounded by the bent portion of the second frame connecting portion 163 can include at least one of the side surfaces of the first stopper 23, the present disclosure is not limited thereto.

[0201] In another embodiment, the portion surrounded by the bent portion of the second frame connecting portion 163 can include at least a partial region of the side surface of the first stopper 23.

[0202] For example, the portion surrounded by the bent portion of the second frame connecting portion 163 can include at least one of the side surfaces of the first stopper 230 and a partial region of the other side surface.

[0203] For example, the bent portion of the second frame connecting portion 163 can include a portion positioned between the first stopper 23 and the side surface 92d of the post 216a to 216d.

[0204] For example, the second frame connecting portion 163 can include a portion (or a bent portion) surrounding the remaining side surfaces except for the first side surface of the first stopper 23. The first side surface of the first stopper 23 can be a side surface facing the opening in the base 210.

[0205] The coil 120 can be coupled to the inner frame 161 of the first lower spring 160a and the second lower spring 160b, and can be conductively connected to the first lower spring 160a and the second lower spring 160b.

[0206] Referring to Figure 6 One end of the second inner frame 161 of the first lower spring 160a can be provided with a first bonding portion 19a on an upper surface thereof, to which one end of the coil 120 is bonded, and one end of the second inner frame 161 of the lower spring 160b can be provided with a second bonding portion 19b on an upper surface thereof, to which the other end of the coil 120 is bonded.

[0207] Each of the first bonding portion 19a and the second bonding portion 19b can further have a groove (not shown) configured to guide the coil 120.

[0208] The coil 120 can be bonded to the first bonding portion 19a and the second bonding portion 19b by means of a conductive adhesive member such as solder. The term "bonding portion" in the first bonding portion 19a and the second bonding portion 19b can be replaced with the term "soldering pad portion", "connection terminal", "soldering portion", or "electrode portion".

[0209] In order to prevent an oscillation phenomenon when the bobbin 110 moves, a damper can be provided between the first frame connecting portion 153 of the upper elastic member 150 and the upper surface of the bobbin 110 (for example, the first avoiding recess 112a).

[0210] In addition, a damper (not shown) can also be provided between the second frame connecting portions 163-1 and 163-2 of the lower elastic member 160 and the lower surface of the bobbin 110, for example, the second avoiding recess 112b.

[0211] In addition, a damper can be applied to a coupling portion between the upper elastic member 150 and each of the bobbin 110 and the base 210 and / or a coupling portion between the lower elastic member 160 and each of the bobbin 110 and the base 210. Although the damper can be, for example, a gel-type silicon, the present disclosure is not limited thereto.

[0212] Each of the first lower spring 160a and the second lower spring 160b can be disposed on an upper surface of the base 210.

[0213] Each of the first lower spring 160a and the second lower spring 160b can include a respective one of first and second connection terminals 164a and 164b for electrically connecting to an external component. The term "connection terminal" in the first and second connection terminals 164a and 164b can be used interchangeably with the terms "soldering pad portion", "bonding portion", "soldering portion", or "electrode portion".

[0214] Each of the first lower spring 160-1 and the second lower spring 160-2 can include a respective one of the connection terminals 164a and 164b that is connected to the second outer frame 162 and is bent toward and extends from an outer surface of the side portion 218d of the body 213 of the base 210.

[0215] For example, the first lower spring 160a can include the first connection terminal 164a that is connected to the outer surface of the second outer frame 162-1 and is bent toward and extends from the outer surface of the protrusion 25c positioned at the side portion 218d of the body 213.

[0216] For example, the second lower spring 160b can include the second connection terminal 164b that is connected to the outer surface of the second outer frame 162-1 and is bent toward and extends from the outer surface of the protrusion 25c positioned at the side portion 218d of the body 213.

[0217] For example, the outer surface of the fourth side portion 218d of the body 213 can be a different surface from the outer surface of the first side portion 218a of the body 213 provided with the first magnet 130-1 and the outer surface of the third side portion 218c of the body 213 provided with the second magnet 130-2. For example, the outer surface of the fourth side portion 218d of the body 213 can be perpendicular to the outer surface of the first side portion 218a or the third side portion 218c of the body 213.

[0218] The first and second connection terminals 164a and 164b of the first and second lower springs 160a and 160b can be disposed in the mounting recess 28 in a state spaced apart from each other and can be in contact with the mounting recess 28 in the base 210, which is formed in the outer surface of the protrusion 25c provided at the fourth side portion 218d of the body 213 of the base 210 and the outer surface of the fourth side portion 218d of the body 213.

[0219] For example, the first and second connection terminals 164a and 164b can be disposed at the outer surface of the protrusion 25c of the fourth side portion 218d of the body 213 of the base 210. The reason for this is to easily perform a soldering operation for conductive connection to an external component. However, the present disclosure is not limited thereto. In another embodiment, the first and second connection terminals of the first and second lower springs can also be disposed at the outer surfaces of two different side portions of the base 210.

[0220] Each of the first and second lower springs 160a and 160b can include a respective one of the extensions 62a and 62b extending from the other end portion of the second outer frame 162-1 toward the guide protrusion 27.

[0221] The second outer frame of the first lower spring 160a can be disposed at one side of the guide protrusion 27 of the base 210, and the second outer frame of the second lower spring 160b can be disposed at the outer side of the guide protrusion 27 of the base 210.

[0222] The extension 62a of the second outer frame of the first lower spring 160a can extend from the second outer frame of the first lower spring 160a toward the second outer frame of the second lower spring 160b.

[0223] In addition, the extension 62b of the second outer frame of the second lower spring 160b can extend from the second outer frame of the second lower spring 160b toward the second outer frame of the first lower spring 160a. An adhesive member can be disposed between the guide protrusion 27 and the extensions 62a and 62b.

[0224] The extensions 62a and 62b can increase the bonding area with respect to the guide protrusion 27 to improve the bonding force between the second outer frame 162-1 and the base 210 and inhibit displacement of the second outer frame 162-1 of the lower springs 160a and 160b, thereby preventing the second outer frame 162-1 from being detached from the base 210.

[0225] Next, the magnet 130 will be described.

[0226] Referring to Figure 9 and Figure 10The magnet 130 may be disposed at at least one of the side portions 218a to 218d of the body 213 of the base 210, and the spool 110 may be moved in a first direction by electromagnetic interaction with the coil 120.

[0227] For example, magnet 130 may include a first magnet 130-1 and a second magnet 130-2 facing each other, wherein the first magnet 130-1 is disposed at one of the two side portions 218a and 218c of the body 213 of the base 210, and the second magnet 130-2 is disposed at the other side portion of the two side portions 218a and 218c.

[0228] At the initial position of the AF operating unit, such as the spool 110, the first magnet 130-1 and the second magnet 130-2 disposed at the base 210 may overlap with at least a portion of the coil 120 in a direction perpendicular to the optical axis. Here, the initial position of the AF operating unit, such as the spool 110, may be the initial position of the AF operating unit when no power is applied to the coil 120, or the position where the upper elastic member 150 and the lower elastic member 160 are elastically deformed solely due to the weight of the AF operating unit.

[0229] In addition, the initial position of the AF operating unit can be the position of the AF operating unit when gravity acts in the direction from the spool 110 to the base 210 or when gravity acts in the direction from the base 210 to the spool 110.

[0230] Although each of the first magnet 130 and the second magnet 130 may have a shape corresponding to the shape of each of the side portions 218a and 218c of the body 213 of the base 210, such as a cuboid shape, this disclosure is not limited thereto.

[0231] For example, each of the first magnet 130-1 and the second magnet 130-2 may be a unipolar magnetized magnet, which is configured such that a first surface of the unipolar magnetized magnet facing the coil 120 has an S pole, and a second surface opposite to the first surface has an N pole. In another embodiment, the first surface of each of the first magnet 130-1 and the second magnet 130-2 may have an N pole, and the second surface may have an S pole.

[0232] like Figure 10 As shown, the upper surfaces of the first magnet 130-1 and the second magnet 130-2, which are respectively provided at the first side portion 218a and the third side portion 218c of the body 213 of the base 210, can be positioned below the upper surfaces of the pillars 216a to 216d or flush with the upper surfaces of the pillars 216a to 216d.

[0233] In addition, for example, the magnet 130 can be a bipolar magnetization magnet that is divided into two parts in a direction perpendicular to the optical axis. At this time, the magnet 130 can be implemented by ferrite, alnico, a rare earth magnet, or the like.

[0234] The magnet 130 having a bipolar magnetization structure can include a first magnet portion including N and S poles, a second magnet portion including N and S poles, and a non-magnetic separation portion. The first magnet portion and the second magnet portion can be spaced apart from each other, and the non-magnetic separation portion can be positioned between the first magnet portion and the second magnet portion. The non-magnetic separation portion can be a portion that is substantially free of magnetism, can include a section having a smaller polarity, and can be filled with air or can be made of a non-magnetic material.

[0235] Although the number of magnets 130 is two in this embodiment, the present disclosure is not limited thereto. In another embodiment, the number of magnets 130 can be at least two. Although the surface of each of the magnets 130 facing the coil 120 can be flat, the present disclosure is not limited thereto. The surface of each magnet can be curved.

[0236] A typical lens moving device is configured to include three injection-molded parts, i.e., a bobbin on which a lens is mounted, a housing on which a magnet is mounted, and a base.

[0237] In contrast, this embodiment is configured such that the base 210 also has the functions and roles of the housing, thereby omitting the housing and simplifying the structure of the lens moving device. Accordingly, since the lens moving device does not include a housing part, the number of manufacturing processes and resources required for processing, such as labor and material costs, can be reduced, thereby reducing manufacturing costs.

[0238] Figure 13 is an exploded perspective view of the base 210-1 and first and second magnets 130-1 and 130-2 according to another embodiment. Figure 14 is Figure 13 is an assembled perspective view of the base 210-1 and first and second magnets 130-1 and 130-2 shown in FIG. 10A. Figure 15 is Figure 13 is an enlarged view of the base 210-1 shown in FIG. 10A. Figure 16 is a cross-sectional view of a lens moving device taken along Figure 3 is a cross-sectional view of a lens moving device taken along Figure 13 the base 210-1 shown in FIG. 10A is mounted on the lens moving device. In Figures 13 to 16 the same as those in FIG. 10A can also be used to describe Figures 1 to 12 in FIG. 10A. In Figures 1 to 12The description disclosed in the specification.

[0239] Referring to Figures 13 to 16 The base 210-1 can further include second stoppers 31 provided on upper surfaces or upper end portions of the posts 216a to 216d.

[0240] The term "second stopper 31" can also be used interchangeably with the term "upper stopper".

[0241] The second stopper 31 can be positioned on the second stepped portion 25b (or the upper surface of the second protrusion).

[0242] For example, each of the second stoppers 31 can be configured such that one end or upper end of the second stepped portion 25b protrudes vertically or in the optical axis direction from the upper surface 51 of the post 216a to 216d, and a cross section of the second stopper 31 in a direction perpendicular to the optical axis direction can be the same as that of the protrusion (or the second protrusion) of the first stepped portion 25b. However, the disclosure is not limited thereto, and in another embodiment, the two cross sections can be different from each other.

[0243] For example, one side surface of the second stopper 31 can be an extended surface of the first surface 25b1 of the second stepped portion 25b.

[0244] Based on the upper surface 51 of each of the posts 216a to 216d, the height H2 of the second stopper 31 can be greater than the height H1 of each of the first protrusions 22 (H2 > H1). In another embodiment, the height H2 can also be equal to the height H1.

[0245] In addition, from the upper surface 51 of each of the posts 216a to 216d, the height of the second stopper 31 can be greater than the height of the upper elastic member 150 coupled to the first protrusion 22.

[0246] The second stopper 31 can serve to secure a space or gap in which the line barrel 110 can move during the AF operation.

[0247] The base 210-1 can further include a groove 41a formed in the upper surfaces of the first and third side portion 218a and 218c, and a groove 41b formed or provided in the side surfaces 92a of the posts 216a to 216d.

[0248] The groove 41a can be provided in the upper surfaces between the first and second corner portions 217a and 217b of the body 213, and between the third and fourth corner portions 217c and 217d of the body 213.

[0249] For example, the groove between the first corner portion 217a and the second corner portion 217b can be formed in the second surface 25a2 of the first stepped portion 25a to face the first magnet 130-1.

[0250] For example, the groove 41a between the third corner portion 217c and the fourth corner portion 217d can be formed in the second surface of the third stepped portion to face the second magnet 130-2.

[0251] The groove 41a can extend from one of two adjacent posts (e.g., 216a and 216b, 216c and 216d) to the other and can abut the two posts (e.g., 216a and 216b, 216c and 216d).

[0252] The groove 41b can be provided in the second stepped portion 25b of each of the first post 216a and the second post 216b to face the first magnet 130-1. Also, the groove 41b can be provided in the fourth stepped portion of each of the third post 216c and the fourth post 216d to face the second magnet 130-2.

[0253] The groove 41b can extend from the lower end of each of the posts 216a to 216d to the upper end of the post (or the stepped portion 49 (see Figure 15 )) and can abut the lower end of each of the posts 216a to 216d and the upper end of the post (or the stepped portion 49).

[0254] For example, each of the groove 41a and the groove 41b can be linear, and the grooves 41a and 41b can be directly connected to each other. Although the groove 41a can be perpendicular to the groove 41b, the disclosure is not limited thereto.

[0255] The groove 41a can function as a channel configured to guide the adhesive member 75 to allow the adhesive member 75 to effectively flow and be uniformly distributed between the upper surfaces 91 of the side portion 218a and 218c of the body of the base 210-1 and the lower surfaces of the first magnet 130-1 and the second magnet 130-2.

[0256] The groove 41b can function as a channel configured to guide the adhesive member 75 to allow the adhesive member 75 to effectively flow and be uniformly distributed between the side surfaces 92 of the posts 216a to 216d and the first magnet 130-1 and the second magnet 130-2. Although the adhesive member 75 can be, for example, a UV-adhesive member, the disclosure is not limited thereto.

[0257] The adhesive member 75 can be disposed in the grooves 41a and 41b. In other words, since the adhesive member 75 can be uniformly supplied to the upper surfaces 91 of the side portions 218a and 218c and the side surfaces 92a of the pillars 216a to 216d, the bonding force between the base 210-1 and the first magnet 130-1 and the second magnet 130-2 can be increased.

[0258] For example, the groove 41a can be positioned to align with the center (or centerline) between the first surface 25a1 of the upper surface 91 in the first step portion 25a (or the first protrusion) and each of the side portions 218a and 218c of the body 213 of the base 210-1.

[0259] The groove 41b can be positioned to align with the center (or centerline) of the center surface 92a of the side surface 92a of each of the columns 216a to 216d or the center surface 25b2 of the second step portion 25b.

[0260] The base 210-1 may include a stepped portion 49 having a depth DP3 from the upper surface 51 of each of the columns 216a to 216d toward the lower surface.

[0261] The upper end of each of the columns 216a to 216d in the base 210-1 may have a double-step structure due to the step portion 49. The step portion 49 may be positioned below the upper surface 51 of each of the columns 216a to 216d.

[0262] For example, the upper surface of the step portion 49 may be parallel to the upper surface of each of the columns 216a to 216d. The groove 41b may be adjacent to the upper surface of the step portion 49.

[0263] like Figure 14 As shown, the upper surface of the second stop portion 31 can be positioned higher than the upper end or upper surface of each of the first magnet 130-1 and the second magnet 130-2 mounted on the base 210-1. The upper end or upper surface of each of the first magnet 130-1 and the second magnet 130-2 can be positioned above the upper surface of the step portion 49.

[0264] An adhesive member 75, intended to bond each of the first magnet 130-1 and the second magnet 130-2 to the base 210-1, may be provided or supplied to the stepped portion 49. Here, the stepped portion 49 may be used to facilitate the supply or application of the adhesive member 75.

[0265] The base 210-1 may also include an adhesive injection recess 47a provided in the outer surface of the side portions 218a and 218c of the body 213, and an adhesive injection recess 47b provided in the side surfaces 92b of the pillars 216a to 216d.

[0266] The adhesive injection recess 47a can be provided in the first outer surface of the body 213 of the base 210, and the first outer surface of the body 213 can be an outer surface of the first side surface or the third side surface of the body 213. For example, the adhesive injection recess 47a can be formed in the outer surface of the body 213 adjacent to the upper surface of the body 213 in which the groove 41a is formed. The side surface 92b of each of the posts 216a to 216d can be a side surface parallel to the first outer surface of the body 213.

[0267] The adhesive injection recess 47a can be connected to the first stepped portion 25a.

[0268] For example, the adhesive injection recess 47a can be contiguous with the upper surface 91 of each of the side portions 218a and 218c of the body 213 of the base 210-1, and can be open at the upper surface of each of the side portions 218a and 218c of the body 213.

[0269] The adhesive injection recess 47b can be connected to the second stepped portion 25b. For example, the adhesive injection recess 47b can be connected to the second surface 25b2 of the second stepped portion 25b.

[0270] The adhesive injection recess 47b can be contiguous with the side surface of each of the posts 216a to 216d, and can be open at the side surface 92a of each of the posts 216a to 216d.

[0271] By fixing the first and second magnets 130-1 and 130-2 to the base 210-1 and then applying the adhesive member 75 via the adhesive injection recesses 47a and 47b, the binding force between the base 210-1 and the first and second magnets 130-1 and 130-2 can be further increased.

[0272] Figure 17a is a perspective view of a base 210-2 according to another embodiment. Figure 17b is Figure 17a is a plan view of the base 210-2 shown in Figure 18 is Figure 17a is a plan view of the base 210-2 and the spool 110 shown in

[0273] Referring to Figures 17a to 18 , as Figure 13 The base 210-2, which is a modification of the base 210-1 shown in, can further include the protrusions 71a to 71d provided at the inner surface or the side surface 92d of at least one of the posts 216a to 216d.

[0274] Here, the protrusions 71a to 71d can function to suppress the degree of rotation of the bobbin 110 about the optical axis. The term "protrusion" used with reference to the protrusions 71a to 71d can be used interchangeably with the terms "suppression portion", "stopper", "support step portion", and the like.

[0275] For example, the base 210-2 can include protrusions 71a to 71d corresponding to the respective columns 216a to 216d. Although a single protrusion is provided for each of the columns in Figure 17a the disclosure is not limited thereto. In another embodiment, the protrusions can be provided at at least two of the columns.

[0276] Each of the protrusions 71a to 71d provided at the base 210-2 can protrude from the inner surface or the side surface 92d of each of the columns 216a to 216d toward the outer surface of the first side portion 110b-1 of the bobbin 110.

[0277] The distance d1 (see FIG. 6) between the outer surface of the first side portion 110b-1 of the bobbin 110 and a respective one of the protrusions 71a to 71d can be smaller than the distance d2 between the outer surface of the first side portion 110b-1 of the bobbin 110 and the inner surface or the side surface 92d of a respective one of the columns 216a to 216d (d1 < d2). Figure 19 For example, the distance d1 can be the minimum distance between the outer surface of the first side portion 110b-1 of the bobbin 110 and a respective one of the protrusions 71a to 71d. The distance d2 can be the minimum distance between the outer surface of the first side portion 110b-1 of the bobbin 110 and the inner surface or the side surface of a respective one of the columns 216a to 216d.

[0278] The outer surface of the first side portion 110b-1 of the bobbin 110 can be an outer surface facing a respective one of the columns 216a to 216d, and the side surface 92d of the respective one of the columns 216a to 216d can be an inner surface facing the outer surface of the first side portion 110b-1.

[0279] For example, each of the protrusions 71a to 71d of the base 210-2 can be provided at the side surface 92d and the side surface 92e of a respective one of the columns 216a to 216d, and can extend toward an adjacent one of the side portions 218b and 218d of the body 213 of the base 210.

[0280]

[0281] ​For example, each of the protrusions 71a to 71d of the base 210-2 can protrude from the side surface 92c of a corresponding one of the posts 216a to 216d toward a corresponding one of the side portion 218b and 218d of the body 213.

[0282] For example, each of the protrusions 71a to 71d of the base 210-2 can be in a bent form.

[0283] Figure 19 is Figure 18 an enlarged view of the dotted area 11 in FIG.

[0284] Referring to Figure 19 , each of the protrusions 71a to 71d can include a first portion 81a and a second portion 81b, wherein the first portion is disposed on the side surface 92d of each of the posts 216a to 216d, the second portion 81b is bent from and extends from the first portion 81a, and the second portion 81b protrudes from the side surface 92c of each of the posts 216a to 216d. For example, the side surface 92c of each of the posts 216a to 216d can be one of side surfaces of the first and fourth posts 216a and 216d facing each other and side surfaces of the second and third posts 216b and 216c facing each other. For example, the side surface 92c can be a side surface facing the protrusion 25c.

[0285] For example, each of the protrusions 71a to 71d of the base 210-2 can include a first portion 81a and a second portion 81b (see Figure 19 ), wherein the first portion 81a is disposed at the side surface 92d of a corresponding one of the posts 216a to 216d, and the second portion 81b is disposed at the side surface 92e. The second portion 81b can be bent from the first portion 81a.

[0286] Although each of the protrusions 71a to 71d can be spaced apart from the side surface 92a and / or the first stepped portion 25a of a corresponding one of the posts 216a to 216d to avoid spatial interference with a corresponding one of the first and second magnets 130-1 and 130-2, the present disclosure is not limited thereto.

[0287] Although a bending angle between the first portion 81a and the second portion 81b of each of the protrusions 71a to 71d can be equal to an angle between the side surface 92d and the side surface 92e of each of the posts 216a to 216d, the present disclosure is not limited thereto. For example, the bending angle between the first portion 81a and the second portion 81b of each of the protrusions 71a to 71d can be an obtuse angle.

[0288] For example, the lateral length L2 of the second portion 81b of each of the protrusions 71a to 71d can be smaller than the lateral length L1 of the first portion 81a of each of the protrusions 71a to 71d (L2 < L1). However, the present disclosure is not limited to this. In another embodiment, the lateral length L2 of the second portion 81b of each of the protrusions 71a to 71d can also be equal to or smaller than the lateral length L1 of the first portion 81a of each of the protrusions 71a to 71d.

[0289] Further, for example, the lateral length L1 of the first portion 81a of each of the protrusions 71a to 71d can be smaller than the lateral length of the side surface 92d of each of the posts 216a to 216d. The reason for this is to reduce foreign matter or particles generated due to contact or collision with the spool 110 by reducing the surface area of the protrusions 71a to 71d that can come into contact with the spool.

[0290] Although the thickness of the first portion 81a of each of the protrusions 71a to 71d can be equal to the thickness of the second portion 81b, the present disclosure is not limited to this. In another embodiment, the thickness of the first portion can be greater than or smaller than the thickness of the second portion.

[0291] Although in the embodiment shown in Figure 17a , each of the protrusions 71a to 71d includes both the first portion 81a and the second portion 81b, the present disclosure is not limited to this. In another embodiment, each of the protrusions can include only one of the first portion and the second portion.

[0292] The protrusions 71a to 71d can abut the upper surface of the body 213 of the base 210-2, and can be connected to the protrusions 25c of the base 210-2.

[0293] For example, the second portion 81b of the protrusions 71a to 71d can be connected to the protrusions 25c of the base 210-2.

[0294] For example, the second portion 81b of the protrusions 71a to 71d can abut the inner surface of the protrusions 25c of the base 210.

[0295] Each of the protrusions 71a to 72d can be spaced apart from a corresponding one of the support protrusions 24, and can be positioned between the support protrusions 24 and the side surface 92d of each of the posts 216a to 216d.

[0296] The height of the protrusions 71a to 71d can be greater than the height of the protrusion 25c of the base 210-2 based on the upper surface of the body 213 of the base 210-2, but can be less than the height of the upper surface of the posts 216a to 216d.

[0297] For example, the height of the protrusions 71a to 71d can be greater than the height of the second protrusion 21 and the height of the first stopper 23 based on the upper surface of the body 213 of the base 210-2.

[0298] At the initial position of the bobbin 110, the protrusions 71a to 71d can overlap the coil 120 in a direction from the first corner portion toward the second corner portion and in a direction from the first corner portion toward the fourth corner portion.

[0299] Because the protrusions 71a to 71d overlap the coil 120, the coil 120 mounted on the bobbin 110 comes into contact with the protrusions 71a to 71d due to the rotation of the bobbin 110, thereby inhibiting the rotation of the bobbin 110 beyond a predetermined angle.

[0300] In another embodiment, one of the outer surfaces of the bobbin 110 comes into contact with the protrusions 71a to 71d due to the rotation of the bobbin 110, thereby inhibiting the rotation of the bobbin 110 beyond a predetermined angle.

[0301] Accordingly, the generation of foreign matter or particles due to the collision of the protrusions 71a to 71d with the bobbin 110 can be reduced, thereby preventing the deformation or breakage of the bobbin 110 or the base 210.

[0302] The protrusions 71a to 71d can serve to increase the durability of the posts 216a to 216d of the base 210, and can prevent the bending or deformation of the posts 216a to 216d due to the collision.

[0303] According to the present embodiment, the protrusions 71a to 71d are capable of inhibiting the rotation of the bobbin 110 beyond a desired degree due to the impact, and thus are capable of reducing the generation of foreign matter due to the contact of the bobbin 110 with the posts of the base 210. In addition, the protrusions 71a to 71d can also serve as stoppers in a direction perpendicular to the optical axis, and can also serve to prevent the bending of the posts.

[0304] At the initial position of the bobbin 110, the outer surface of the first side portion 110-1 of the bobbin 110 can be spaced apart from a corresponding one of the protrusions 71a to 71d of the base 210-2.

[0305] At the initial position of the spool 110, the first corner portion 39a of the spool 110 can overlap with the protrusion (e.g., the protrusion 71a) in a direction from the first post 216a toward the second post 216b and in a direction from the second post 216b toward the third post 216c.

[0306] At the initial position of the spool 110, the first corner portion 39a of the spool 110 can overlap with the side surface 92e of each of the posts 216a to 216d in a direction from the first post 216a toward the second post 216b.

[0307] At the initial position of the spool 110, the first corner portion 39a of the spool 110 can overlap with the side surface 92d of each of the posts 216a to 216d in a direction from the first post 216a toward the fourth post 216d.

[0308] The first corner portion 39a of the spool 110 can be a corner portion at which an outer surface of the first side portion portion 110b-1 of the spool 110 meets an outer surface of the second side portion portion 110b-2 of the spool 110.

[0309] For example, the first corner portion 39a of the spool 110 can be a corner portion at which a first outer surface of the spool 110 meets a second outer surface of the spool 110, the first outer surface of the spool 110 can be an outer surface facing a respective one of the posts 216a to 216d, and the second outer surface of the spool 110 can be an outer surface that is adjacent to the first outer surface and extends in a direction from the first post 216a toward the fourth post 216d.

[0310] At the initial position of the spool 110, the second corner portion 39b of the spool 110 can overlap with the first step portion (or the first protrusion) 25a of the base 210-2 in a direction from the first post 216a toward the fourth post 216d.

[0311] The second corner portion 39b of the spool 110 can be a corner portion at which the first side portion portion 110b-1 of the spool 110 meets the second side portion portion 110b-2 of the spool 110, the second side portion portion 110b-2 corresponding to each of the side portion portions 218a and 218c of the base 210-2.

[0312] Figure 19 The dashed line PS shown in FIG. 13 indicates a position of the spool 110 when the spool 110 is rotated clockwise by a predetermined angle, e.g., an angle of 2 degrees from the initial position of the spool 110.

[0313] When the spool 110 rotates clockwise by a predetermined angle, for example, 2 degrees, the second side portion 110b-2 of the spool 110 contacts the protrusion 71a of the base 210-2, thus the protrusion 71a inhibits further clockwise rotation of the spool 110.

[0314] For example, the protrusions 71a to 71d can prevent the spool 110 from rotating clockwise or counterclockwise from its initial position beyond a predetermined angle.

[0315] The predetermined angle can be, for example, between 2 and 5 degrees. The predetermined angle can be, for example, 2 degrees.

[0316] The second frame connection portion 163 may include a bent portion surrounding three side surfaces of the first stop portion 23. The bent portion may include a portion positioned between the first stop portion 23 and a corresponding one of the protrusions 71a to 71d, and may be spaced apart from the first stop portion 23 and the corresponding one of the protrusions 71a to 71d.

[0317] Figure 20 This is a perspective view of the base 210-3 according to another embodiment.

[0318] Figure 20 The base 210-3 shown is Figure 17a The base 210-2 shown is a modification. In this embodiment, based on the upper surface of the body 213 of the base 210-3, the height of the protrusion 72 can be greater than the height of the protrusion 25c, and can be equal to the height of the upper surfaces of the pillars 216a to 216d.

[0319] At the initial position of the tube 110, the protrusion 72 can overlap with the coil 120 in a direction perpendicular to the optical axis.

[0320] Figure 21 This is a perspective view of the base 210-4 according to another embodiment. Figure 22 yes Figure 21 The plan view of the base 210-4 shown.

[0321] Figure 21 and Figure 22 The base 210-4 shown is Figure 17a Another modification of the base 210-2 shown. Each of the protrusions 73 in the base 210-4 may be provided on the side surface 92d, side surface 92e, and side surface 92c of a corresponding one of the columns 216a to 216d. The protrusion 73 may have a portion positioned on the second stepped portion 25b of the column.

[0322] For example, the protrusion 73 can include a first portion, a second portion, and a third portion, where the first portion is disposed at the side surface 92d of a respective one of the posts 216a to 216d, the second portion is disposed at the side surface 92e of the post, and the third portion is disposed at the side surface 92c of the post.

[0323] The second portion of the protrusion 73 can be bent from one end of the first portion of the protrusion 73, and the third portion of the protrusion 73 can be bent from the other end of the first portion of the protrusion 73.

[0324] For example, the lateral length of the first portion of the protrusion 73 can be equal to the lateral length of the side surface 92d of each of the posts 216a to 216d.

[0325] The height of the protrusion 73 can be greater than the height of the protrusion 25c of the base 210-4, but can be less than the height of the upper surface of the posts 216a to 216d, based on the upper surface of the body 213 of the base 210-4.

[0326] For example, the height of the protrusion 73 can be greater than the height of the second protrusion 21 and the height of the first stopper 23, based on the upper surface of the body 213 of the base 210-4.

[0327] At the initial position of the bobbin 110, the protrusion 73 can overlap the coil 120 in a direction perpendicular to the optical axis.

[0328] Figure 23 FIG. 18 is a perspective view of a base 210-5 according to another embodiment.

[0329] Figure 23 The base 210-5 shown in FIG. 18 can be a modification of the base 210-4 shown in FIG. 17. Figure 21 The base 210-5 shown in FIG. 18 can be a modification of the base 210-4 shown in FIG. 17.

[0330] The base 210-5 can include a body including an opening and first to fourth corner portions positioned around the opening, a first post 216a-1 disposed at the first corner portion, a second post 216-b disposed at the second corner portion, a third post 216c-1 disposed at the third corner portion, and a fourth post 216d-1 disposed at the fourth corner portion. The description regarding the body of the base 210-2 can be applied to the body of the base 210-5.

[0331] At least one of the first to fourth posts 216a-1 to 216d-1 can include a first side surface 23a facing a first outer surface of the bobbin 110 and a second side surface 23b bent from one end of the first side surface 23a.

[0332] At least one of the posts can further include a third side surface 23c bent from the other end of the first side surface 23a.

[0333] The second side surface 23b can extend in a direction parallel or opposite to a direction from the first post 216a-1 toward the fourth post 216d-1.

[0334] For example, the second side surface 23b can protrude from the side surface 92c of the at least one post. The side surface of the post can be one of side surfaces of the first post 216a-1 and the fourth post 216d-1 facing each other and side surfaces of the second post 216b-1 and the third post 216c-1 facing each other.

[0335] The side surface 23b of the at least one post can extend to face the second outer surface of the bobbin 110.

[0336] The first outer surface of the bobbin 110 can be an outer surface of the bobbin 110 facing the at least one post or an outer surface of the first side portion 110b-1 of the bobbin 110.

[0337] The second outer surface of the bobbin 110 can be an outer surface adjacent to the first outer surface of the bobbin 110 and parallel to a direction from the first post 216a-1 toward the fourth post 216d-1.

[0338] A lateral length of the second side surface 23b can be less than a lateral length of the first side surface 23a.

[0339] In an initial position of the bobbin 110, the first side surface 23a of the at least one post can overlap the coil 120 in a direction from the first corner portion 216a-1 toward the second corner portion 216b-1 and can overlap the coil 120 in a direction from the first corner portion 216a-1 toward the fourth corner portion 216d-1.

[0340] The outer surfaces of the posts 216a to 216d and the outer surfaces of the side portions 218a to 218d of the body 213 of each of the bases 210-2 to 210-5 and the inner surfaces of the side plates of the cover member 300 can be bonded or fixed to each other by means of an adhesive member, for example, a UV-adhesive member.

[0341] In the outer surfaces of the posts 216a to 216d and the outer surfaces of the side portions 218a to 218d of each of the bases 210-2 to 210-5, a guide groove 61 configured to allow easy and uniform application of an adhesive member therein can be formed.

[0342] Each of the guide grooves 61 can include a first guide groove 61a horizontally extending and a second guide groove 61b vertically extending. The first guide groove 61a and the second guide groove 61b can be adjacent to each other and can each have a strip shape.

[0343] For example, the first guide groove 61a can include two or more linear grooves spaced apart from and parallel to each other.

[0344] For example, the second guide groove 61b can include two or more linear grooves spaced apart from and parallel to each other.

[0345] At least one of the first guide groove 61a and the second guide groove 61b can be adjacent to the adhesive injection recess 47b. The adhesive member injected into the adhesive injection recess 47b can easily move to the side portion 218a and 218c of the body 213 of the base 210-2 to 210-5 through the grooves 41a and 41b, thereby increasing the coupling force between the first magnet 130-1 and the second magnet 130-2 and each of the bases 210-2 to 210-5.

[0346] In addition, the adhesive member injected into the adhesive injection recess 47b can easily move to the outer surface of each of the bases 210-2 to 210-5 through the guide grooves 61, thereby increasing the coupling force between each of the bases 210-2 to 210-5 and the cover member 300.

[0347] The first protrusion portion corresponding to the first stepped portion 25a of Figures 1 to 23 The first protrusion portion corresponding to the first stepped portion 25a of the body 213 can be described in the term of "protrusion portion" since it protrudes from the upper surface of the body 213, and the second protrusion portion corresponding to the second stepped portion 25b can be described in the term of "protrusion portion" since it protrudes from the side surface 92a of the post. However, the disclosure is not limited thereto. In other words, the "protrusion portion" can be alternatively the term of "groove portion". For example, the first grooving portion can be denoted as being provided in the upper surface of the body 213 between the first post 216a and the second post 216b and between the third post 216c and the fourth post 216d, and the second grooving portion can be denoted as being provided in the side surface of the post 216a to 216d facing the first magnet 130-1 and the second magnet 130-2.
