[0076] The following detailed description of the features and advantages of the present disclosure is sufficient to enable any person skilled in the art to understand the technical content of the present disclosure and implement it accordingly. Furthermore, based on the disclosure of this specification, the claims, and the accompanying drawings, any person skilled in the art can easily understand the relevant objectives and advantages of the present disclosure. The following examples further illustrate the concepts of the present disclosure but are not intended to limit the scope of the present disclosure in any way.
[0077] The present disclosure provides an imaging lens module, which includes an optical element, a photosensitive element, a first driving unit, a second driving unit, a third driving unit, and a base.
[0078] The optical element has an optical axis, and the photosensitive element and the optical element are correspondingly arranged on the optical axis. The photosensitive element can be moved relative to the optical element by being driven by the driving element.
[0079] The first driving part is used to drive the photosensitive element to move along a first direction perpendicular to the optical axis. The first driving part includes at least one first coil and at least one first magnet, and the first magnet is correspondingly arranged to the first coil.
[0080] The second driving unit is used to drive the photosensitive element to move in a second direction perpendicular to the optical axis, wherein the second direction is different from the first direction. The second driving unit includes at least one second coil and at least one second magnet, and the second magnet is arranged corresponding to the second coil. In the present disclosure, the first driving unit and the second driving unit enable the photosensitive element to move in a direction perpendicular to the optical axis to achieve the function of optical image stabilization (OIS). In addition, the first driving unit and the second driving unit are also used to cooperate with each other to drive the photosensitive element to rotate around the optical axis. In detail, if the direction of the optical axis is defined as the Z axis, the photosensitive element can move in any direction on an XY plane defined by the X axis and Y axis perpendicular to the optical axis, and rotate on the XY plane. Among them, the number of coils and magnets (that is, the first coil and the first magnet and / or the second coil and the second magnet) of at least one of the first driving part and the second driving part can be at least two respectively; thereby, when the number of coils and magnets of the first driving part and the second driving part increases, it can help to improve the accuracy (Accuracy) of the rotation angle of the photosensitive element in the plane perpendicular to the optical axis.
[0081] The third driving part is used to drive the photosensitive element to move in a direction parallel to the optical axis, and the third driving part includes at least one third coil and at least one third magnet. The third magnet and the third coil are correspondingly arranged in the direction parallel to the optical axis. In the present disclosure, the third driving part enables the photosensitive element to move in the direction parallel to the optical axis to achieve the function of autofocus (AF). Specifically, if the direction of the optical axis is defined as the Z axis, the photosensitive element can move along the direction parallel to the Z axis. Among them, the number of the third coils and the third magnets of the third driving part can be at least two, and the third coils and the third magnets are arranged in pairs; thereby, the collimation of the photosensitive element moving in the direction parallel to the optical axis can be improved. Among them, the third driving part can be farther away from the optical element than the first driving part and the second driving part.
[0082] The base is correspondingly and fixedly arranged with the optical element. The fixed arrangement of the base and the optical element may mean that the optical element is directly or indirectly fixedly arranged on the base, so that a fixed distance is maintained between the optical element and the base. Among them, the third coil can be arranged on the base.
[0083] According to the imaging lens module disclosed in the present disclosure, by fixedly arranging the optical element and the base to maintain a fixed distance, and combining with the movable photosensitive element, the image captured by the imaging lens module can be stabilized, and the imaging lens module can perform autofocus. And by arranging multiple groups of the above driving parts, the movement of the photosensitive element can be controlled more precisely, so that the photosensitive element can be displaced in the direction parallel to the optical axis and displaced and rotated in the direction perpendicular to the optical axis relative to the optical element to further meet the requirements of anti-shake.
[0084] In one embodiment, the imaging lens module may further include a movable plate. Among them, the first magnet, the second magnet and the third magnet can be arranged on the movable plate, and the third driving part can be used to drive the movable plate to move in the direction parallel to the optical axis. The setting positions of the third magnet and the third coil in the present disclosure are not limited to the above. For example, in another embodiment, the third magnet can be arranged on the base, and the third coil can be arranged on the movable plate.
[0085] There is an intersection point between the most image-side surface of the optical element and the optical axis. The distance between the center point of the first magnet and the intersection point in the direction parallel to the optical axis is h1, the distance between the center point of the second magnet and the intersection point in the direction parallel to the optical axis is h2, and the distance between the center point of the third magnet and the intersection point in the direction parallel to the optical axis is h3, which can satisfy the following conditions: 0≤h1 = h2 < h3. Please refer to Figure 4, is a schematic diagram showing the parameters h1, h2, and h3 in the first embodiment of the present disclosure. Among them, the image-side surface of the optical element 102 has an intersection point P0 with the optical axis OL. The distance between the center point M1 of the first magnet 109b and the intersection point P0 in the direction parallel to the optical axis OL is h1, the distance between the center point M2 of the second magnet 110b and the intersection point P0 in the direction parallel to the optical axis is h2, and the distance between the center point M3 of the third magnet 111b and the intersection point P0 in the direction parallel to the optical axis is h3. The image-side surface of the optical element refers to the surface of the optical element closest to the photosensitive element. In addition, it should be noted that the generally referred optical axis can be obtained by simplifying multiple optical axes of the optical element (such as the principal optical axis and the sub-optical axis). Therefore, the present disclosure is not limited to the positions of the optical axis and the intersection point in the drawings. In the present disclosure, the intersection point between the image-side surface of the optical element and the optical axis refers to the intersection point between the image-side surface of the optical element and the principal optical axis of the optical element, where the principal optical axis can pass through the optical center of the optical element, for example, or there may be a slight offset between the principal optical axis and the optical center. Among them, when there is a slight offset between the principal optical axis and the optical center, the intersection point can be located near the optical center of the optical element, for example.
[0086] The distance between the center point of the third magnet and the intersection point in the direction parallel to the optical axis is h3, and the back focal length of the optical element is BFL, which can satisfy the following condition: BFL < h3. The back focal length of the optical element refers to the distance parallel to the optical axis between the intersection point and the photosensitive element. Among them, the optical element, the photosensitive element, and the third magnet can be arranged in sequence from the object side to the image side in the direction parallel to the optical axis. Please refer to Figure 4 , is a schematic diagram showing the parameters BFL and h3 in the first embodiment of the present disclosure. Among them, the image-side surface of the optical element 102 has an intersection point P0 with the optical axis OL, and the distance parallel to the optical axis OL between the intersection point P0 and the photosensitive element 104 is the back focal length BFL of the optical element 102.
[0087] The imaging lens module may further include a frame member. The frame member carries the photosensitive element, and the movable plate is correspondingly arranged with the frame member. Among them, the frame member and the movable plate can be arranged in sequence from the object side to the image side in the direction parallel to the optical axis. In one embodiment, the movable plate can be correspondingly arranged with the frame member and the base. Among them, the movable plate can be arranged between the frame member and the base, and the frame member, the movable plate, and the base can be arranged in sequence from the object side to the image side in the direction parallel to the optical axis. Among them, the first coil and the second coil can be arranged on the frame member. However, the first magnet, the second magnet, the first coil, and the second coil of the present disclosure are not limited to the foregoing arrangement positions. For example, in another embodiment, the first magnet and the second magnet can be arranged on the frame member, and the first coil and the second coil can be arranged on the movable plate.
[0088] The movable plate may have at least one first sidewall, and the first sidewall may include at least one first groove. The base may have at least one second sidewall, and the second sidewall may include at least one second groove. The first groove and the second groove are correspondingly arranged, and together they form a track parallel to the optical axis; thereby, the movable plate can move along the track in a direction parallel to the optical axis. Furthermore, movement along a fixed movement path can prevent the movable plate from deviating in the direction parallel to the optical axis. The number of each of the first groove and the second groove can be at least two, thereby correspondingly forming at least two sets of tracks; thereby, the balance of movement can be improved, and the movable plate is less likely to tilt.
[0089] The third driving unit may further include at least one autofocus roller. The autofocus roller is disposed between the movable plate and the base, enabling the movable plate to move relative to the base. The autofocus roller is movably disposed in a track in a direction parallel to the optical axis, and the third driving unit is configured to drive the movable plate to move relative to the optical element in a direction parallel to the optical axis. This ensures more stable movement of the movable plate in a direction parallel to the optical axis. The autofocus roller may be a ball element, but the present disclosure is not limited thereto.
[0090] The first and second drive units may further include at least one image stabilizing roller. The image stabilizing roller is disposed between the frame member and the movable plate, enabling the frame member to move relative to the movable plate. The first and second drive units are configured to drive the frame member and the photosensitive element to translate and rotate relative to the optical element in a direction perpendicular to the optical axis. This ensures more stable movement of the frame member and the photosensitive element in a direction perpendicular to the optical axis. The image stabilizing roller may be a ball element, but the present disclosure is not limited thereto.
[0091] The frame member may include at least one third groove, and the movable plate may include at least one platform structure, wherein the third groove and the platform structure are correspondingly disposed, and the image stabilization roller is disposed between the third groove and the platform structure, and the image stabilization roller is configured to translate and rotate on the platform structure in a direction perpendicular to the optical axis. The platform structure may not have a fixed track path, and the image stabilization roller is configured to translate and rotate on the platform structure in a direction perpendicular to the optical axis, thereby providing the image stabilization roller with at least three degrees of freedom in directions perpendicular to the optical axis.
[0092] The imaging lens module may further include a lens barrel and a housing. The lens barrel accommodates optical elements. The housing is mechanically fixed to the lens barrel, and the housing is assembled to the base. The housing can be mechanically fixed to the base by screw locking, interlocking, active alignment (AA), etc., and can be fixed by dispensing glue after positioning, but the mechanical fixing method disclosed in this disclosure is not limited to this. Among them, the housing and the lens barrel need to consider whether the mechanical fixing method will affect the imaging quality of the optical elements. In addition, the method of assembling the housing to the base can be a method of assembling the housing in cooperation with each other. In addition, the configuration of assembling the housing to the base can prevent optical elements, photosensitive elements and other components from getting dust, but this disclosure is not limited to this.
[0093] The lens barrel and housing can be integrally formed, thereby simplifying the assembly process and improving production efficiency.
[0094] The imaging lens module may further include a flexible circuit board. The flexible circuit board is electrically connected to the photosensitive element, wherein the flexible circuit board includes at least one bending portion, and at least one bending portion is a bending portion with an angle on the flexible circuit board. The flexible circuit board is configured to cooperate with the movement of the photosensitive element during autofocus or image stabilization, so a partial area of the flexible circuit board has an angled bend to avoid mechanical interference during the movement of the flexible circuit board. The partial area is the bending portion. The bending portion generates a crease due to the angled bend, which gives the appearance of the flexible circuit board a specific shape. Please refer to Figure 2 and Figure 3 , is a schematic diagram illustrating the bent portion 108 a of the flexible printed circuit board 108 according to the first embodiment of the present disclosure.
