[0061] In the following description, embodiments of the present invention that specifically achieve the above objectives will be described with reference to the accompanying drawings.

[0062] In the following description of the embodiments, it will be understood that when an element is referred to as being formed “on” or “below” another element, the element may be directly “on” or “below” the other element, or may be disposed indirectly, wherein there is one or more intermediate elements between the element and the other element. Additionally, it will be understood that “on” or “below” an element may indicate an upward or downward direction based on the element.

[0063] Additionally, relative terms such as “first,” “second,” “upper,” “lower,” and “below” used in the following description may be used to distinguish any substance or element from another substance or element without implying any physical or logical relationship or order between these substances or elements. In all the accompanying drawings, the same reference numerals denote the same elements.

[0064] Unless otherwise defined, the terms “comprising,” “including,” or “having” as used in the above description are used to specify the presence of the features, steps, or combinations thereof described in the specification, and should be understood as not excluding the presence or possibility of one or more different features, steps, or combinations thereof.

[0065] Furthermore, when describing components of this disclosure, terms such as “first,” “second,” “A,” “B,” “(a),” or “(b)” may be used. Since these terms are provided only to distinguish a component from other components, they do not limit the nature, sequence, or order of the components. If a component is described as “connected,” “linked,” or “attached” to another component, it should be understood that although the component may be directly connected, linked, or attached to another component, the component and the other component may also be indirectly “connected,” “linked,” or “attached” via the other component.

[0066] In the following description, a lens moving device according to an embodiment of the present disclosure will be described with reference to the accompanying drawings. For ease of description, although a Cartesian coordinate system (x, y, z) is used to describe the lens moving device, other coordinate systems may also be used, and the embodiments are not limited thereto. In the various drawings, the X-axis and Y-axis refer to directions perpendicular to the optical axis, i.e., the Z-axis, and the direction of the optical axis OA or a direction parallel to the optical axis OA may be referred to as the "first direction," the X-axis direction may be referred to as the "second direction," and the Y-axis direction may be referred to as the "third direction."

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

[0068] An "autofocus device" used in ultra-miniature camera modules of mobile devices such as smartphones or tablets is a device that automatically focuses an image of an object onto the surface of an image sensor. The autofocus device can be constructed in various ways, and according to an embodiment, a lens moving device can move an optical module consisting of at least one lens in a first direction to perform autofocus.

[0069] Figure 1This is a perspective view of the lens moving device 100 according to the embodiment. Figure 2 yes Figure 1 An exploded view of the lens moving device 100 shown. Figure 3 It shows Figure 1 The lens moving device 100 shown is used to remove the cover member 300.

[0070] Reference Figures 1 to 3 The lens moving device 100 may include a cover member 300, a spool 110, a coil 120, a magnet 130, an upper elastic member 150, a lower elastic member 160, and a base 210.

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

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

[0073] The cover member 300 may take the form of a box with an open bottom and including a top plate and side plates. The lower end of the side plate of the cover member 300 may be attached to the top of the base 210. The top plate of the cover member 300 may have a polygonal shape, such as a square or octagonal shape.

[0074] The cover member 300 may have an opening in its upper plate, through which the lens unit 400 connected 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 is made of a non-magnetic material, this embodiment prevents the magnet 130 from attracting 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 may be provided in the lower end of at least one of the side plates of the cover member 300.

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

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

[0079] Figure 4a yes Figure 2 The three-dimensional view of the spool 110 shown. Figure 4b yes Figure 4a A three-dimensional view of the spool 110 and the coil shown.

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

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

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

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

[0084] The spool 110 may include at least one first connecting portion 113 and at least one second connecting portion 117, wherein the at least one first connecting portion 113 is located on the upper surface of the spool 110 and is connected and fixed to the inner frame 151 of the upper elastic member 150, and the at least one second connecting portion 117 is located on the lower surface of the spool 110 and is connected and fixed to the inner frame 161 of the lower elastic member 160.

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

[0086] The spool 110 may have an upper avoidance recess 112a, which is disposed on the upper surface of the spool 110 in a region corresponding to or aligned with the first frame connection portion 153 of the upper elastic member 150.

[0087] In addition, the spool 110 may have a lower avoidance recess 112b, which is disposed on the lower surface of the spool 110 in a region corresponding to or aligned with the second frame connection portions 163-1 and 163-2 of the lower elastic member 160.

[0088] When the spool 110 moves along the first direction, the upper avoidance recess 112a and the lower avoidance recess 112b of the spool 110 can avoid spatial interference between the first frame connecting portion 153 and the spool 110, and between the second frame connecting portions 163-1 and 163-2 and the spool 110. This allows the first frame connecting portion 153 of the upper elastic member 150 and the second frame connecting portions 163-1 and 163-2 of the lower elastic member 160 to easily deform elastically.

[0089] The spool 110 may have at least one mounting recess 105 in its outer surface 110b, and the coil 120 may be placed or mounted in the mounting recess 105 in the spool 110. For example, as Figure 4a As shown, the mounting recess 105 may have a ring shape arranged around the optical axis OA; however, this disclosure is not limited thereto.

[0090] The shape and number of mounting recesses 105 can correspond to the shape and number of coils disposed around the outer surface 110b of the bobbin 110. In another embodiment, the bobbin 110 may not have recesses for mounting coils.

[0091] The spool 110 may include a first outer portion 110b-1 and a second outer portion 110b-2, wherein the first outer portion 110b-1 corresponds to the posts 216a to 216d of the base 210, and the second outer portion 110b-2 corresponds to the region between the posts 216a to 216d.

[0092] Next, coil 120 will be described.

[0093] The outer portion and outer surface of the coil 120 winding spool 110 are provided, and it interacts electromagnetically with the magnet 130 provided at the base 210.

[0094] In order to generate an electromagnetic force due to the electromagnetic interaction with the magnet 130, a driving signal can be applied to the coil 120. This driving signal can be a DC signal, or it can be in the form of a voltage or current.

[0095] The autofocus (AF) operating unit, elastically supported by the upper elastic member 159 and the lower elastic member 160 via the electromagnetic interaction generated between the coil 120 and the magnet 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 the autofocus function.

[0096] The AF operating unit may include a spool 110 elastically supported by an upper elastic member 150 and a lower elastic member 160, and components mounted on the spool 110 and moving together with the spool. For example, the AF operating unit may include the spool 110 and the coil 120.

[0097] Reference Figure 4b The coil 120 can be wound or set around the outer peripheral surface of the coil 110 in a clockwise or counterclockwise direction around the optical axis OA.

[0098] For example, the coil 120 may be disposed or wound in the mounting recess 105 provided on the outer surface of the spool 110.

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

[0100] In another embodiment, coil 120 can be implemented as a coil loop wound around an axis perpendicular to the optical axis OA in a clockwise or counterclockwise direction. Although the number of coil loops can be equal to the number of magnets 130, this 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 may include a first post 216a, a second post 216b, a third post 216c, and a fourth post 216d, which protrude upwards to a predetermined height from the first corner portion 217a to the fourth corner portion 217d.

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

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

[0112] The body 213 of the base 210 may include an upper surface and an outer surface, and may include a first surface positioned inside the first post 216a to the fourth post 216d around the opening and a second surface positioned outside the first surface and above the first surface.

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

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

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

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

[0117] The base 210 may include openings located between two adjacent posts 216a and 216b, between two adjacent posts 216b and 216c, between two adjacent posts 216c and 216d, and between two adjacent posts 216d and 216a, and located on the first step portion 25a and the protrusion 25c.

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

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

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

[0121] The first magnet 130-1 and the second magnet 130-2 can be disposed at the first step portion 25a and the second step portion 25b. The first step portion 25a and the second step portion 25b can be used to support the first magnet 130-1 and the second magnet 130-2 to prevent the first magnet 130-1 and the second magnet 130-2 from tilting inward.

[0122] The first step portion 25a may have a depth DP1 relative to the outer surface of the body 213, and the second step portion 25b may have a depth DP2 relative to the outer surface of the pillars 216a to 216d.

[0123] For example, each of the first step portions 25a may include a first surface 25a1 and a second surface 25a2, wherein the first surface 25a1 is a step surface having a depth relative to a corresponding outer surface of 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 corresponding outer surface of 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 may include a first surface 25b1 and a second surface 25b2, wherein the first surface 25b1 is a step surface having a depth relative to a corresponding outer surface of the outer surfaces 92b of the columns 216a to 216d, and the second surface 25b2 is positioned between the corresponding outer surface of the outer surfaces 92b of the columns 216a to 216d and the first surface 25b1.

[0125] For example, the base 210 may include first stepped portions 25a, each of the first stepped portions 25a having a depth DP1 relative to a first outer surface of the body 213 (e.g., the outer surface of the first side portion 218a of the body 213) and positioned between the first post 216a and the second post 216b. For example, the outer surface of the body 213 may be the outer surface of the side portion of the body 213 where the first magnet 130-1 is disposed.

[0126] For example, each of the first pillar 216a and the second pillar 216b may include a second step portion 25b having a depth DP2 relative to a first outer surface 92b of each of the first pillar 216a and the second pillar 216b. For example, the outer surface 92b of each of the first pillar 216a and the second pillar 216b may be the outer surface between the outer surfaces of the first pillar 216a and the second pillar 216b that is adjacent to a first side portion 218a of the body 213.

[0127] In addition, the base 210 may include a third step portion having a depth relative to the second outer surface of the body 213 (e.g., the outer surface of the third side portion 218c of the body 213) and positioned between the third post 216c and the fourth post 216d.

[0128] Each of the third pillar 216c and the fourth pillar 216d may include a fourth step portion having a depth relative to a first outer surface of each of the third pillar 216c and the fourth pillar 216d. For example, the outer surface of each of the third pillar 216c and the fourth pillar 216d may be the outer surface adjacent to the third side portion 218c of the body 213.

[0129] For example, the first magnet 130-1 can be disposed at the first step portion 25a and the second step portion 25b, and the surface of the first magnet 130-1 can contact the first surface 25a1 of the first step portion 25a and the first surface 25b1 of the second step portion 25b.

[0130] For example, the second magnet 130-2 can be disposed at the third step portion and the fourth step portion, and the surface of the second magnet 130-2 can contact the first surface of the third step portion and the first surface of the fourth step portion.

[0131] For example, the first depth DP1 can be equal to the second depth DP2. For mounting 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 the 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 the 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 step portion 25a and the first surface 25b1 of the second step portion 25b can prevent the adhesive member 75 (see...) Figure 15 The adhesive component 75 flows toward the spool 110 of the lens moving device 100, and the adhesive injection is carried out through the adhesive injection recesses 47a and 47b to attach the first magnet 130-1 and the second magnet 130-2 to the base 210.

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

[0134] For example, the "first protrusion" may be positioned between the first post 216a and the second post 216b and between the third post 216c and the fourth post 216d, and may protrude vertically from the upper surface of the side portion of the body. For example, the vertical direction may be 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" may protrude from the side surface of each of the posts 216a to 216d along a first horizontal direction. For example, the first horizontal direction may be the 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 relative to the side surface 92a of each of the pillars 216a to 216d may be equal to the second height of the second protrusion relative to the side surface 92a of each of the pillars 216a to 216d, this disclosure is not limited thereto. In another embodiment, the first height may be greater than the second height. In another embodiment, the first height may be less than the second height. The side surface 92a of each of the pillars 216a to 216d may be the second surface 25b2 of the second step 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 may be provided with a protrusion 25c, which protrudes from the upper surface of the body 213 of the base 210 in a vertical or optical axis direction. The protrusion 25c may protrude from the upper surface around an 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 also 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 may abut against the side surfaces of two adjacent posts (e.g., 216a and 216d, 216b and 216c), this disclosure is not limited thereto.

[0149] Each of the columns 216a to 216d may also include a side surface 92d positioned between the second step portion 25b and the side surface 92c. This side surface of each of the columns 216a to 216d may be the surface facing the first side portion 110b-1 of the spool 110.

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

[0151] For example, the side surface 92d of each of columns 216a to 216d can be an imaginary plane or line parallel to or parallel to the side surface 92b of each of columns 216a to 216d at a predetermined angle θ1 (see [reference]). Figure 11 ) An inclined surface.

[0152] Although the angle θ1 of the side surface 92d of each of the columns 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 spool 110 corresponding to the side surface 92d of each of the columns 216a to 216d, this disclosure is not limited thereto.

[0153] The angle θ1 of the side surface 92d of each of columns 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 columns 216a to 216d can be in the range of 40 degrees to 50 degrees.

[0154] Each of the columns 216a to 216d may also include a side surface 92e, which is positioned between side surfaces 92c and 92d.

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

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

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

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

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

[0160] The first stop 23 of the base 210 can prevent the lower surface or 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 may include a support protrusion 24 protruding from the upper surface of the body 213.

[0162] Each of the support protrusions 24 can connect the first step portion (or the first protrusion) disposed between two adjacent side portions 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 step portion (or the first protrusion) 25a to the inner surface of the protrusion 25c.

[0164] Each of the support protrusions 24 can be used to support the first step 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 step 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 posts 216a to 216d and the opening in the base 210, and the first stop 23 can be positioned on the support protrusion 24.

[0166] For connection to the upper elastic member 150, the base 210 may include a first protrusion 22, which is disposed on at least one upper portion or upper surface of the posts 216a to 216d.

[0167] For example, the base 210 may include at least one first protrusion 22 projecting from the upper surface of the posts 216a to 216d.

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

[0169] Furthermore, the lower elastic member 160 can be connected to the base 210 between the second post 216b and the third post 216c adjacent to the second post 216b.

[0170] The lower elastic member 160 may not be connected to the base 210 between the first post 216a and the second post 216b, or between the third post 216c and the fourth post 216d.

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

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

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

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

[0175] A guide protrusion 27 may be provided on the fourth side portion 218d of the body 213 of the base 210. The guide protrusion 27 may be provided at the protrusion 25c provided at the fourth side portion 218d of the body 213. The guide protrusion 27 may be used to stably fix the portions of the second outer frames of the lower springs 160-1 and 160-2 adjacent to the connecting terminals 164a and 164b by increasing the contact area with the extensions 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 may be formed in the outer surface of the fourth side portion 218d of the body 213 of the base 210, and the connecting terminals 164a and 164b of the lower springs 160a and 160b are provided in the mounting recess 28.

[0178] The lower end of the outer surface of the body 213 of the base 210 may be provided with a stepped portion 211. The stepped portion 211 may contact the lower end of the side plate of the cover member 300 and may 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 may be fixed to each other in an adhesive and sealing manner and may 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] Reference Figure 6 and Figure 8 The upper elastic member 150 and the lower elastic member 160 can be connected to the spool 110 and the base 210, and can elastically support the spool 110.

[0181] The upper elastic member 150 can be connected to the upper part, upper surface or upper end of the spool 110, and can be connected to the upper part, upper surface or upper end of the posts 216a to 216d of the base 210.

[0182] The lower elastic member 160 can be connected to the lower portion, lower surface or lower end of the spool 110, and can be connected 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, this 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, etc.

[0184] The upper elastic member 150 may include: a first inner frame 151, the first inner frame 151 being connected to a first connecting portion 113 of the bobbin 110; a first outer frame 152, the first outer frame 152 being connected to a first protrusion 22 of the base 210; and a first frame connecting portion 153, the 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 the upper surface of the columns 216a to 216d and on the upper surface of the first magnet 130-1 and the second magnet 130-2.

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

[0187] The first inner frame 151 of the upper elastic member 150 may be provided with a through hole or groove 151a to connect with the first connecting portion 113 of the bobbin 110, and the first outer frame 152 may be provided with a through hole or groove to connect with the first protrusion 22 of the base 210.

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

[0189] Furthermore, the first inner frame 151 of the upper elastic member 150, which is connected to the bobbin 110, can be tilted or bent to be lower than the first outer frame 152 fixed to the posts 216a to 216d.

[0190] The lower elastic member may include a first lower spring 160a and a second lower spring 160b, which are positioned inside the posts 126a to 126d and spaced apart from each other. The first lower spring 160a and the second lower spring 160b may be spaced apart from each other and may be electrically isolated from each other.

[0191] Each of the first lower spring 160a and the second lower spring 160b may include: a second inner frame 161, the second inner frame 161 to be connected to a second connecting portion 117 of the spool 110; second outer frames 162-1 and 162-2; and second frame connecting portions 163-1 and 163-2, the second frame connecting portions 163-1 and 163-2 configured to connect the second inner frame 161 to the second outer frames 162-1 and 162-2.

[0192] For example, the second outer frame 162 may be disposed on the upper surface of the side portions 218b and 218d and / or on 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 may 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 second inner frames, the number of second outer frames, and the number of second frame connecting portions are not limited thereto.

[0194] Each of the two outer frames 162-1 and 162-2 can be connected to a corresponding second protrusion in the second protrusion 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 may be provided with a through hole or groove for connection with the second connecting portion 117 of the spool 110, and the second outer frames 162-1 and 162-2 may be provided with a through hole or groove 162a for connection with the second protrusion 21 of the base 210.

[0196] With the aid of adhesives or heat fusion, the through holes 151a in the first connecting portion 113 and the first inner frame 151 can be joined to each other, the through holes 161a in the second connecting portion 117 and the second inner frame 152 of the bobbin 110 can be joined to each other, the through holes 152a in the first protrusion 22 of the base 210 and the first outer frame 152 can be joined to each other, and the through holes 162a in the second protrusion 21 of the base 210 and the second outer frames 162-1 and 162-2 can be joined 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 folded at least once to define a predetermined pattern.

[0198] By means of the positional changes and slight deformations of the first frame connecting portion 153 and the second frame connecting portion 163, the upward and / or downward movement of the spool 110 in the first direction can be elastically (or flexibly) supported.

[0199] The second frame connection portion 163 may be a portion (or a bent portion) of at least a part of the side surface surrounding the first stop portion 23.

[0200] Although the portion surrounded by the bent portion of the second frame connection portion 163 may include at least one side surface of the side surface of the first stop portion 23, this disclosure is not limited thereto.

[0201] In another embodiment, the portion surrounded by the bent portion of the second frame connection portion 163 may include at least one local area of ​​the side surface of the first stop portion 23.

[0202] For example, the portion surrounded by the bent portion of the second frame connection portion 163 may include at least one side surface of the side surface of the first stop portion 230 and local areas of other side surfaces.

[0203] For example, the bent portion of the second frame connection portion 163 may include the portion that positions the first stop portion 23 between the side surfaces 92d of the posts 216a to 216d.

[0204] For example, the second frame connection portion 163 may include portions (or bends) of the remaining side surfaces surrounding the first stop portion 23, other than the first side surface. The first side surface of the first stop portion 23 may be the side surface facing the opening in the base portion 210.

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

[0206] Reference Figure 6 One end of the second inner frame 161 of the first lower spring 160a may have a first connecting portion 19a on its upper surface, and one end of the coil 120 is connected to the first connecting portion 19a. One end of the second inner frame 161 of the lower spring 160b may have a second connecting portion 19b on its upper surface, and the other end of the coil 120 is connected to the second connecting portion 19b.

[0207] Each of the first connecting portion 19a and the second connecting portion 19b may also 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 component, such as solder. The term "bonding portion" in the first bonding portion 19a and the second bonding portion 19b can be replaced by the terms "pad portion", "connection terminal", "solder portion" or "electrode portion".

[0209] To prevent oscillations when the drum 110 moves, a damper can be provided between the first frame connection portion 153 of the upper elastic member 150 and the upper surface of the drum 110 (e.g., the first avoidance recess 112a).

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

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

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

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

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

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

[0216] For example, the second lower spring 160b may include a second connecting terminal 164b, which is connected to the outer surface of the second outer frame 162-1 and bends toward the outer surface of the protrusion 25c located at the side portion 218d of the body 213 and extends from the outer surface of the protrusion 25c located 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 may be a different surface from the outer surface of the first side portion 218a of the body 213 where the first magnet 130-1 is provided and the outer surface of the third side portion 218c of the body 213 where the second magnet 130-2 is provided. For example, the outer surface of the fourth side portion 218d of the body 213 may 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 connecting terminals 164a and the second connecting terminals 164b of the first lower spring 160a and the second lower spring 160b can be provided in the mounting recess 28 in a spaced-apart state and can contact the mounting recess 28 in the base 210. The mounting recess 28 is formed on the outer surface of the protrusion 25c provided on the fourth side portion 218d of the body 213 of the base 210 and on the outer surface of the fourth side portion 218d of the body 213.

[0219] For example, the first connecting terminal 164a and the second connecting terminal 164b may be provided on the outer surface of the protrusion 25c of the fourth side portion 218d of the body 213 of the base 210. This is to facilitate welding operations for conductive connection to external components. However, this disclosure is not limited thereto. In another embodiment, the first connecting terminals and the second connecting terminals of the first lower spring and the second lower spring may also be provided on the outer surfaces of two different side portions of the base 210.

[0220] Each of the first lower spring 160a and the second lower spring 160b may include a corresponding extension of extensions 62a and 62b extending from the other end 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 on 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 on the outside 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] Furthermore, 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 contact area relative to the guide protrusion 27 to improve the contact force between the second outer frame 162-1 and the base 210 and suppress the displacement of the second outer frame 162-1 of the lower springs 160a and 160b, thereby preventing the second outer frame 162-1 from detaching from the base 210.

[0225] Next, magnet 130 will be described.

[0226] Reference Figure 9 and Figure 10 The 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] Alternatively, for example, magnet 130 can be a bipolar magnetized magnet divided into two parts in a direction perpendicular to the optical axis. In this case, magnet 130 can be made of ferrite, alnico, rare earth magnets, etc.

[0234] The magnet 130 having a bipolar magnetization structure may include: a first magnet portion including an N pole and a S pole; a second magnet portion including an N pole and a S pole; and a non-magnetic separator. The first magnet portion and the second magnet portion may be spaced apart from each other, and the non-magnetic separator may be positioned between the first magnet portion and the second magnet portion. The non-magnetic separator may be a substantially non-magnetic portion, may include segments with a smaller polarity, and may be filled with air or may be made of a non-magnetic material.

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

[0236] A typical lens moving device is constructed to include three injection-molded components: a spool with the lens mounted, a housing with the magnet mounted, and a base.

[0237] In contrast, this embodiment is configured such that the base 210 also functions as a housing, thereby eliminating the need for a housing and simplifying the structure of the lens moving device. Therefore, since the lens moving device does not include a housing component, the number of manufacturing steps and the resources required for processing, such as labor and material costs, can be reduced, thus lowering manufacturing costs.

[0238] Figure 13 This is an exploded perspective view of the base 210-1, the first magnet 130-1, and the second magnet 130-2 according to another embodiment. Figure 14 yes Figure 13 The figure shows an assembled perspective view of the base 210-1, the first magnet 130-1, and the second magnet 130-2. Figure 15 yes Figure 13 An exploded enlarged view of the base 210-1 shown. Figure 16 It is along Figure 3 The cross-sectional view of the lens moving device taken along the AB direction is shown in the figure. Figure 13 The base 210-1 shown is mounted on the lens moving device. Figures 13 to 16 In the accompanying reference numerals shown, the same as... Figures 1 to 12 The same reference numerals are used to describe the figures. Figures 1 to 12 The description published in the document.

[0239] Reference Figures 13 to 16 The base 210-1 may also include a second stop 31, which is disposed on the upper surface or upper end of the posts 216a to 216d.

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

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

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

[0243] For example, one side surface of the second stop portion 31 may be an extension surface of the first surface 25b1 of the second step portion 25b.

[0244] Based on the upper surface 51 of each of the columns 216a to 216d, the height H2 of the second stop 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] Furthermore, the height of the second stop portion 31 on the upper surface 51 of each of the columns 216a to 216d can be greater than the height of the upper elastic member 150 connected to the first protrusion 22.

[0246] The second stop 31 can be used to ensure the space or gap that the spool 110 can move during AF operation.

[0247] The base 210-1 may also include a groove 41a formed in the upper surfaces of the first side portion 218a and the third side portion 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 surface between the first corner portion 217a and the second corner portion 217b of the body 213, and in the upper surface between the third corner portion 217c and the fourth corner portion 217d of the body 213.

[0249] For example, a groove between the first corner portion 217a and the second corner portion 217b can be formed in the second surface 25a2 of the first step 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 step portion to face the second magnet 130-2.

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

[0252] The groove 41b may be provided in the second step portion 25b of each of the first post 216a and the second post 216b, facing the first magnet 130-1. In addition, the groove 41b may be provided in the fourth step portion of each of the third post 216c and the fourth post 216d, facing the second magnet 130-2.

[0253] The groove 41b may 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 be adjacent to the lower end of each of the columns 216a to 216d and the upper end (or step portion 49) of the column.

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

[0255] The groove 41a can be used as a channel to guide the adhesive member 75, so as to allow the adhesive member 75 to flow effectively and be evenly distributed between the upper surface 91 of the side portions 218a and 218c of the body of the base 210-1 and the lower surface of the first magnet 130-1 and the second magnet 130-2.

[0256] The groove 41b can be used as a channel configured to guide the adhesive member 75, allowing the adhesive member 75 to flow effectively and be evenly distributed between the side surfaces 92 of the pillars 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, this 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 14As 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 may be provided in the first outer surface of the body 213 of the base 210, and the first outer surface of the body 213 may be the outer surface of either the first side surface or the third side surface of the body 213. For example, the adhesive injection recess 47a may 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 pillars 216a to 216d may 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 step portion 25a.

[0268] For example, the adhesive injection recess 47a may be adjacent to the upper surface 91 of each of the side portions 218a and 218c of the body 213 of the base 210-1, and may 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 may abut against the side surface of each of the pillars 216a to 216d and may open at the side surface 92a of each of the pillars 216a to 216d.

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

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

[0273] Reference Figures 17a to 18 As Figure 13 The modified base 210-2 of the base 210-1 shown may further include protrusions 71a to 71d provided on the inner surface or side surface 92d of at least one of the columns 216a to 216d.

[0274] Here, the protrusions 71a to 71d can be used to suppress the degree of rotation of the spool 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 part", "stop part", "support step part", etc.

[0275] For example, the base 210-2 may include protrusions 71a to 71d corresponding to the respective posts 216a to 216d. Although in Figure 17a The illustration shows a single protrusion for each column in the column array, but this disclosure is not limited thereto. In another embodiment, protrusions may be provided at at least two columns in the column array.

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

[0277] The distance d1 between the outer surface of the first side portion 110b-1 of the spool 110 and a corresponding protrusion among the protrusions 71a to 71d (see...) Figure 19 The distance d2 (d1 < d2) between the outer surface of the first side portion 110b-1 of the spool 110 and the inner surface or side surface 92d of the corresponding column 216a to 216d can be less than the distance between the outer surface of the first side portion 110b-1 of the spool 110 and the inner surface or side surface 92d of the corresponding column 216a to 216d.

[0278] For example, distance d1 can be the minimum distance between the outer surface of the first side portion 110b-1 of the spool 110 and a corresponding protrusion among the protrusions 71a to 71d. Distance d2 can be the minimum distance between the outer surface of the first side portion 110b-1 of the spool 110 and the inner or side surface of a corresponding post among the posts 216a to 216d.

[0279] The outer surface of the first side portion 110b-1 of the spool 110 may be the outer surface facing one of the corresponding columns 216a to 216d, and the side surface 92d of the corresponding column 216a to 216d may be the inner surface facing the outer surface of the first side portion 110b-1.

[0280] For example, each of the protrusions 71a to 71d of the base 210-2 may be provided at the side surface 92d and side surface 92e of a corresponding one of the columns 216a to 216d, and may extend toward an adjacent side portion of the side portions 218b and 218d of the body 213 of the base 210.

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

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

[0283] Figure 19 yes Figure 18 Enlarged view of the dashed area 11 in the image.

[0284] Reference Figure 19 Each of the protrusions 71a to 71d may 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 bends 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 may be one of the side surfaces of the first post 216a and the fourth post 216d facing each other, and the side surfaces of the second post 216a and the third post 216c facing each other. For example, the side surface 92c may be the side surface facing the protrusion 25c.

[0285] For example, each of the protrusions 71a to 71d in the base 210-2 may include a first portion 81a and a second portion 81b (see...). Figure 19 The first part 81a is located on the side surface 92d of one of the columns 216a to 216d, and the second part 81b is located on the side surface 92e. The second part 81b can be bent from the first part 81a.

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

[0287] Although the bending angle between the first portion 81a and the second portion 81b of each of the protrusions 71a to 71d can be equal to the angle between the side surface 92d and the side surface 92e of each of the columns 216a to 216d, this 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 may be less than the lateral length L1 of the first portion 81a of each of the protrusions 71a to 71d (L2 < L1). However, this disclosure is not limited thereto. In another embodiment, the lateral length L2 of the second portion 81b of each of the protrusions 71a to 71d may also be equal to or less than the lateral length L1 of the first portion 81a of each of the protrusions 71a to 71d.

[0289] Furthermore, for example, the lateral length L1 of the first portion 81a of each of the protrusions 71a to 71d can be less than the lateral length of the side surface 92d of each of the columns 216a to 216d. This is done 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 may come into contact with the spool.

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

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

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

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

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

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

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

[0297] For example, on the upper surface of the body 213 based on the base 210-2, 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 stop 23.

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

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

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

[0301] Therefore, the generation of foreign objects or particles due to the collision between the protrusions 71a to 71d and the spool 110 can be reduced, thereby preventing deformation or breakage of the spool 110 or the base 210.

[0302] The protrusions 71a to 71d can be used to increase the durability of the columns 216a to 216d of the base 210 and to prevent the columns 216a to 216d from bending or deforming due to impact.

[0303] According to this embodiment, the protrusions 71a to 71d can suppress the rotation of the bobbin 110 from exceeding the desired level due to impact, thus reducing the generation of foreign objects caused by the contact between the bobbin 110 and the column of the base 210. In addition, the protrusions 71a to 71d can also serve as stops in the direction perpendicular to the optical axis, and can also be used to prevent the column from bending.

[0304] At the initial position of the spool 110, the outer surface of the first side portion 110-1 of the spool 110 can be spaced apart from one of the corresponding 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 may overlap with the protrusion (e.g., protrusion 71a) in the direction from the first post 216a toward the second post 216b and in the 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 may overlap with the side surface 92e of each of the columns 216a to 216d in the direction from the first column 216a toward the second column 216b.

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

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

[0309] For example, the first corner portion 39a of the spool 110 may be a corner portion where the first outer surface of the spool 110 meets the second outer surface of the spool 110. The first outer surface of the spool 110 may be the outer surface facing one of the corresponding columns 216a to 216d, and the second outer surface of the spool 110 may be the outer surface adjacent to the first outer surface and extending in the direction from the first column 216a toward the fourth column 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 first protrusion) 25a of the base 210-2 in the direction from the first post 216a toward the fourth post 216d.

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

[0312] Figure 19 The dashed line PS shown indicates the position of the spool 110 when it is rotated clockwise by a predetermined angle, for example, at 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 may include a first part, a second part, and a third part, wherein the first part is disposed at the side surface 92d of a corresponding one of the columns 216a to 216d, the second part is disposed at the side surface 92e of the column, and the third part is disposed at the side surface 92c of the column.

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

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

[0325] Based on the upper surface of the body 213 of the base 210-4, 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 pillars 216a to 216d.

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

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

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

[0329] Figure 23 The base 210-5 shown can be Figure 21 The base 210-4 shown is a modified version.

[0330] The base 210-5 may 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 a second corner portion; a third post 216c-1 disposed at a third corner portion; and a fourth post 216d-1 disposed at the fourth corner portion. The description of 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 post 216a-1 to the fourth post 216d-1 may include a first side surface 23a facing the first outer surface of the spool 110 and a second side surface 23b bent from one end of the first side surface 23a.

[0332] At least one of the columns may also include a third side surface 23c, which is bent from the other end of the first side surface 23a.

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

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

[0335] At least one column's side surface 23b may extend into a second outer surface facing the tube 110.

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

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

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

[0339] At the initial position of the coil 110, at least one first side surface 23a of the column may overlap with the coil 120 in the direction from the first corner portion 216a-1 toward the second corner portion 216b-1, and may overlap with the coil 120 in the direction from the first corner portion 216a-1 toward the fourth corner portion 216d-1.

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

[0341] A guide groove 61 may be formed in the outer surface of the pillars 216a to 216d of each of the bases 210-2 to 210-5 and in the outer surface of the side portions 218a to 218d of the body 213. The guide groove 61 is configured to allow the adhesive member to be applied easily and uniformly in the guide groove 61.

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

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

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

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

[0346] Furthermore, the adhesive member injected into the adhesive injection recess 47b can be easily moved to the outer surface of each of the bases 210-2 to 210-5 via the guide groove 61, thereby increasing the bonding force between each of the bases 210-2 to 210-5 and the cover member 300.

[0347] Corresponding to Figures 1 to 23The first protrusion of the first step portion 25a can be described using the term "protrusion" because it protrudes from the upper surface of the body 213, and the second protrusion corresponding to the second step portion 25b can also be described using the term "protrusion" because it protrudes from the side surface 92a of the post. However, this disclosure is not limited thereto. In other words, "protrusion" can alternatively be the term "groove portion". For example, the first slotted portion can be represented 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 slotted portion can be represented as being provided in the side surfaces of the posts 216a to 216d facing the first magnet 130-1 and the second magnet 130-2.

Figure 26 yes Figure 24 The cross-sectional view of the lens moving device 1000 shown is taken along line a-a'. Figure 27 yes Figure 24 The cross-sectional view of the lens moving device 1000 shown is taken along line b-b'. Figure 28 According to one embodiment Figure 26 A cross-sectional view of the camera module observed in the image. Figure 29 According to one embodiment Figure 27 A cross-sectional view of the camera module observed in the image. Figure 30 This is a perspective view of the cover 1100 of the lens moving device 1000. Figure 31 This is a perspective view of the base 1400 of the lens moving device 1000. Figure 32 This is an exploded perspective view of the base 1400 of the magnet 1500 of the lens moving device 1000. Figure 33 This is an exploded perspective view of the spool 1200, coil 1300, upper elastic member 1600, and lower elastic member 1700 of the lens moving device 1000.

[0349] In the lens moving device 1000, the spool 1200 can be elastically supported in the vertical direction by the base 1400, and the spool 1200 can move in the vertical direction through electromagnetic interaction between a first drive unit 1300 disposed at the spool 1200 and a second drive unit 1500 disposed at the base 1400. Here, the lens module can move together with the spool 1200 in the vertical direction (along the optical axis direction). As a result, the AF function can be performed.

[0350] The lens moving device 1000 may include a cover 1100, a spool 1200, a first driving unit 1300, a base 1400, a second driving unit 1500, an upper elastic member 1600, and a lower elastic member 1700.

[0351] The first drive unit 1300 can be either a "magnet" or a "coil" depending on the electromagnetic design conditions. The second drive unit 1500 can also be either a "magnet" or a "coil" depending on the electromagnetic design conditions. If the first drive unit 1300 is a "magnet," then the second drive unit 1500 can be a "coil." If the first drive unit 1300 is a "coil," then the second drive unit 1500 can be a "magnet." Accordingly, although both cases exist, the following description will assume that the first drive unit 1300 is a "coil 1300" and the second drive unit 1500 is a "magnet 1500." In another case, the first drive unit can be a "magnet," and the second drive unit can be a "coil."

[0352] The cover 1100 may be an external component of the lens moving device 1000. A base 1400 may be disposed below the cover 1100. The cover 1100 may be attached to the base to define an internal space between the cover 1100 and the base. A spool 1200, a coil 1300, a magnet 1500, an upper elastic member 1600, and a lower elastic member 1700 may be disposed within the cover 1100.

[0353] The cover 1100 may include a metallic material. The cover 1100 may block the introduction of electromagnetic waves from the outside of the cover 1100 into the inside of the cover 1100 or the radiation of electromagnetic waves from the inside of the cover 1100 to the outside of the cover 1100. Therefore, the cover 1100 may be referred to as a "cover component" or a "shielding can". However, the material of the cover 1100 is not limited to this. In one example, the cover 110 may include plastic.

[0354] The cover may include a top plate 1110, a first side plate 1120, a second side plate 1130, a third side plate 1140, a fourth side plate 1150, a first corner portion C1-1, a second corner portion C1-2, a third corner portion C1-3, and a fourth corner portion C1-4.

The top plate 1110 may include a first side edge S1-1, a second side edge S1-2, a third side edge S1-3, and a fourth side edge S1-4.

[0356] The first side plate 1120, the second side plate 1130, the third side plate 1140 and the fourth side plate 1150 can extend downward from the top plate 1110.

[0357] The first side panel 1120 can be bent or folded at the first side edge S1-1 and can extend downward from the first side edge S1-1. The second side panel 1130 can be bent or folded at the second side edge S1-2 and can extend downward from the second side edge S1-2. The third side panel 1140 can be bent or folded at the third side edge S1-3 and can extend downward from the third side edge S1-3. The fourth side panel 1150 can be bent or folded at the fourth side edge S1-4 and can extend downward from the fourth side edge S1-4.

[0358] Therefore, the cover 1100 can be constructed in the form of a cuboid, in which the upper surface has a hole, the lower surface is open, and the corners are rounded. The lower opening in the cover 1100 can be closed by the base 1400.
