DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] The objectives, technical schemes and advantages of the present invention can be more fully understood by reading the following detailed description and examples with reference to the accompanying drawings. It is understood that the present specification is made for the purpose of illustrating the present invention and should not be taken in a limiting sense.

[0017] The first axis direction (or X-axis direction) is a superordinate concept of the first direction X and its opposite direction, i.e., the first axis direction simultaneously includes both the +X direction and the -X direction. Similarly, the second axis direction (or Y-axis direction) is a superordinate concept of the second direction Y and its opposite direction, and the third axis direction (or Z-axis direction) is a superordinate concept of the third direction Z and its opposite direction.

[0018] Please refer to FIG. 1 and FIG. 2. FIG. 1 is a schematic diagram showing the structure of a lens device 100 according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view of the lens device 100 along line II-II in FIG. 1. As shown in the figure, the lens device 100 of this embodiment includes a lens module 101, a support structure 102, a driving device 107, a light path redirecting module 103, an optical filter 104, and an image sensor 105. A light ray from an object side passes through the lens module 101, undergoes multiple reflections in the light path redirecting module 103, changes its traveling direction, reaches the optical filter 104, and then reaches the image sensor 105 through the optical filter 104. The support structure 102 supports the lens module 101 and the driving device 107. The driving device 107 is disposed between the lens module 101 and the support structure 102. The driving device 107 includes at least one driving coil and at least one driving magnet. The driving device 107 drives the lens module 101 along a third axis direction (Z-axis direction) to perform an autofocus (AF) operation, or drives the lens module 101 along a first axis direction (X-axis direction) and a second axis direction (Y-axis direction) to perform an optical image stabilization (OIS) operation.

[0019] In this embodiment, the light path redirecting module 103 is composed of several prisms, the optical filter 104 is an infrared (IR) cut filter, and the image sensor 105 is a charge-coupled device (CCD), but the above elements are merely examples, and the present invention is not limited thereto. Any element having the same function should belong to the category of the present invention. Specifically, the light path redirecting module 103 is composed of one integrally molded prism, or composed of multiple prisms, or the prism can be replaced by a reflecting mirror, and the light from the object side is multi-reflected by the light path redirecting module 103 before reaching the image sensor 105, thereby extending the optical path length, so that the lens device 100 can be equipped with a lens module 101 with a longer effective focal length (EFL) or a longer back focal length (BFL). Therefore, the lens device 100 can be made thin in a limited space, and obtain good optical performance and higher optical magnification. The support structure 102 and the driving device 107 will be described in detail below.

[0020] Please refer to Figures 3 and 4. Figure 3 is a schematic diagram showing the lens module 101 and its support structure 102 of the lens device 100 according to the present embodiment, and Figure 4 is a three-dimensional exploded view of the support structure 102 of Figure 3. As shown in the figure, the support structure 102 has a base 110, a first carrier 111, and a second carrier 114. The first carrier 111 is disposed on the outer periphery of the lens module 101 and mounts the lens module 101. The second carrier 114 is disposed on the outer periphery of the first carrier 111 and mounts the first carrier 111. The base 110 is disposed below the first carrier 111 and the second carrier 114 and mounts the first carrier 111 and the second carrier 114.

[0021] The support structure 102 further includes a plurality of elastic strips 113 and elastic wires 112. The elastic strips 113 extend in a spiral shape on the XY plane and are connected to the first carrier 111 and the second carrier 114. When the first carrier 111 is subjected to an external force (for example, an electromagnetic force from the driving device 107) and moves along the third axial direction Z relative to the second carrier 114, the elastic strips 113 are deformed and curved to move the first carrier 111 along the third axial direction Z, and generate elasticity in the opposite direction to act on the first carrier 111. When the external force is reduced or eliminated, the elasticity of the elastic strips 113 moves the first carrier 111 in the opposite direction to the third axial direction Z to return to the initial position, and no power consumption is required for the return. In a non-operating state without electricity being applied, the elastic strips 113 provide the function of firmly fixing the first carrier 111 to the second carrier 114. In addition, the elastic strip 113 has a helical portion (not shown), and when the lens device 100 is subjected to an external force such as a drop or collision, the helical portion provides a cushioning effect to protect the elastic strip 113 from damage or destruction under excessive tension or stretching force, and the helical portion has the effect of protecting the elastic strip 113, thereby improving the reliability of the lens device 100. The elastic strip 112 extends along the Z-axis direction, and is simultaneously connected to the base 110 and the elastic strip 113, i.e., connected between the base 110 and the second carrier 114. When the second carrier 114 receives an external force (e.g., an electromagnetic force from the driving device 107) and moves along the first axial direction X and / or the second axial direction Y relative to the base 110, the linear elastic body 112 receives the force and bends laterally to move the second carrier 114 in the first axial direction X and / or the second axial direction Y, and generates an elastic force in the opposite direction to act on the second carrier 114, and when the external force decreases or disappears, the elastic force of the linear elastic body 112 moves the second carrier 114 in the opposite direction of the first axial direction X and the second axial direction Y to return to the initial position, and does not require power consumption for the return. In a non-operating state without electricity being applied, the linear elastic body 112 provides an action of firmly fixing the second carrier 114 on the base 110.It can be understood that the driving device 107 can move the first carrier 111 relative to the second carrier 114 along a third axis direction (Z-axis direction) to perform an autofocus (AF) operation, and move the second carrier 114 relative to the base 110 along a first axis direction (X-axis direction) and / or a second axis direction (Y-axis direction) to perform an optical image stabilization (OIS) operation. The first axis direction, the second axis direction, and the third axis direction are perpendicular to each other.

[0022] A first recess 132 is provided on the outer surface of the first carrier 111, a second recess 133 facing the first recess 132 is provided on the inner surface of the second carrier 114, and a guide element 131 extending along a third axis direction (Z-axis direction) is provided between the first carrier 111 and the second carrier 114. The guide element 131 is provided in the first recess 132 and the second recess 133. When the first carrier 111 moves relative to the second carrier 114, the first carrier 111 moves along the extension direction (third axis direction) of the guide element 131. When the lens device 100 performs an autofocus (AF) operation, the guide element 131 ensures the stability of the movement of the first carrier 111 and can avoid the movement amount in other directions when the first carrier 111 moves relative to the second carrier 114.

[0023] 4 and 5, the driving device 107 includes a first driving coil 122, a first driving magnet 121, a second driving coil 123, a second driving magnet 124, a third driving coil 125, and a third driving magnet 126. A flexible circuit board 119 (or other power supply element) is provided on the base 110 to supply power to the first driving coil 122, the second driving coil 123, and the third driving coil 125 of the driving device 107. In particular, the flexible circuit board 119 is installed on the base 110 and located between the base 110 and the second carrier 114. The base 110 is substantially a rectangular frame. The shape of the flexible circuit board 119 corresponds to the base 110. Thus, the flexible circuit board 119 has two second portions opposite to each other in the X-axis direction and two first portions opposite to each other in the Y-axis direction. As shown in FIG. 4, the first portion and the second portion surround the optical axis of the lens module 101. It should be noted that the first portion is located at a low position, the second portion is located at a high position, and the first portion and the second portion are located on different horizontal planes, that is, the first portion is located farther from the object side of the lens module 101 than the second portion. In other words, the base 110 has a step of height difference, and the flexible circuit board 119 located on the base 110 also has a step of height difference. In this embodiment, the step formed by the first portion and the second portion forms a one-level staircase structure, but the present invention is not limited thereto. The step is a multi-level staircase structure, for example, further includes a third portion, a fourth portion, etc., and the step forms a two-level, three-level, or multi-level staircase structure, and at least one level of the staircase structure is located within the same height to accommodate the element, increase the space utilization rate, and achieve a slimming effect. In this embodiment, a first mounting portion 117 is disposed on the first portion and a second mounting portion 116 is disposed on the second portion, as will be described in more detail below.

[0024] The first driving coil 122 is installed in the first mounting portion 117 of the flexible circuit board 119 and electrically connected to the flexible circuit board 119, the first mounting portion 117 is farther from the object side of the lens module 101 than the second mounting portion 116, the position of the first mounting portion 117 is lower, and the position of the second mounting portion 116 is higher, the first mounting portion 117 and the second mounting portion 116 are respectively located on different horizontal planes, and the first mounting portion 117 and the second mounting portion 116 form a step due to the difference in height. The first driving magnet 121 is fixed to the bottom of the second carrier 114 and installed opposite to the first driving coil 122. The first driving coil 122 interacts with the first driving magnet 121 to generate an electromagnetic force to move the second carrier 114 in the first direction X or in the opposite direction, that is, to move the second carrier 114 along the first axial direction (X-axis direction). Referring to FIG. 6, the first drive magnet 121 generates a magnetic field B1 around it, and the magnetic field lines of the magnetic field B1 pass through the first drive coil 122. When power is supplied by the flexible circuit board 119, a current I1 flows through the first drive coil 122. According to Fleming's left-hand rule, the first drive coil 122 is subjected to an electromagnetic force F1, and at the same time, the first drive magnet 121 is subjected to a reaction force F1'. Since the first drive magnet 121 is fixed to the second carrier 114, the reaction force F1' moves the second carrier 114. When the current I1 of the first drive coil 122 flows in the opposite direction, the reaction force F1' on the second carrier 114 also changes direction, so that the second carrier 114 can move along the first direction X or in the opposite direction to cancel the camera shake in the first direction X or in the opposite direction and compensate the vibration shift along the first axis direction (X direction).

[0025] Similarly, the second drive coil 123 is disposed in the second mounting portion 116 of the flexible circuit board 119 and electrically connected to the flexible circuit board 119. The second drive magnet 124 is fixed to the bottom of the second carrier 114 and disposed opposite to the second drive coil 123. The second drive coil 123 interacts with the second drive magnet 124 to generate an electromagnetic force, thereby moving the second carrier 114 in the second direction Y or the opposite direction, that is, moving the second carrier 114 along the second axis direction (Y axis direction). Referring to FIG. 7, the second drive magnet 124 generates a magnetic field B2 around it, and the magnetic field lines of the magnetic field B2 pass through the second drive coil 123. When power is supplied by the flexible circuit board 119, a current I2 flows through the second drive coil 123, and the second drive coil 123 is subjected to the action of an electromagnetic force F2. At the same time, the second drive magnet 124 is also subjected to a reaction force F2'. Since the second drive magnet 124 is fixed to the second carrier 114, the reaction force F2' moves the second carrier 114, and when the current I2 of the second drive coil 123 flows in the opposite direction, the reaction force F2' acting on the second carrier 114 also changes direction, so that the second carrier 114 moves along the second direction Y or moves in the opposite direction to offset the movement in the second direction Y or the camera shake in the opposite direction, and compensate for the vibration shift along the second axis direction (Y axis direction).

[0026] The third driving magnet 126 is placed on the first driving magnet 121 and is fixed to the bottom of the second carrier 114 in the same manner, i.e., the third driving magnet 126 is closer to the second carrier 114 in the third axial direction (Z-axis direction) than the first driving magnet 121. The third driving coil 125 is fixed to the first carrier 111 and electrically connected to the flexible circuit board 119 or a flexible circuit board (not shown) on the first carrier 111, and the third driving coil 125 is installed opposite the third driving magnet 126 and the first driving magnet 121, and as shown in FIG. 5, the third driving coil 125 is located on the same side of the first driving magnet 121 and the third driving magnet 126. The third driving coil 125 acts with the third driving magnet 126 to generate an electromagnetic force, thereby moving the first carrier 111 in the third direction Z or in the opposite direction, i.e., moving the first carrier 111 along the third axial direction (Z-axis direction). 8, the third drive magnet 126 generates a magnetic field B3 in its periphery, and the magnetic field lines of the magnetic field B3 pass through the third drive coil 125. When power is supplied by the flexible circuit board 119, a current I3 flows through the third drive coil 125, and the third drive coil 125 is subjected to an electromagnetic force F3. Since the third drive coil 125 is fixed on the first carrier 111, the electromagnetic force F3 moves the first carrier 111. When the current I3 of the third drive coil 125 flows in the opposite direction, the electromagnetic force F3 also changes direction and acts on the first carrier 111, so that the first carrier 111 can move in the third direction Z or in the opposite direction to perform an autofocus operation.

[0027] As described above, the first carrier 111 is disposed on the outer periphery of the lens module 101 and mounts the lens module 101. The second carrier 114 is disposed on the outer periphery of the first carrier 111 and mounts the first carrier 111. The base 110 is disposed below the first carrier 111 and the second carrier 114 and mounts the first carrier 111 and the second carrier 114. The flexible circuit board 119 is disposed between the base 110 and the second carrier 114. Thus, in the lens device 100, the lens module 101, the second carrier 114 (or the first carrier 111), the flexible circuit board 119, and the base 110 are sequentially arranged along the optical axis, and the base 110 is furthest from the object side. The position of the first portion (first mounting portion 117) on the flexible circuit board 119 is low, and the position of the second portion (second mounting portion 116) is high. That is, the first portion (first mounting portion 117) is farther from the object side, and the second portion (second mounting portion 116) is closer to the object side. The present invention utilizes the upper space created by the low position of the first portion (first mounting portion 117) to install the first drive magnet 121, the third drive magnet 126, and the third drive coil 125. Thus, the lens device 100 of the present invention has a reduced thickness compared to the conventional technology.

[0028] 4, structurally, the position of the first portion (first mounting portion 117) is low, and the position of the second portion (second mounting portion 116) is high. That is, this structural design forms a step on the flexible circuit board 119, and the first portion (first mounting portion 117) and the second portion (second mounting portion 116) are located on different steps. Alternatively, this structural design forms a stair-like structure on the flexible circuit board 119, and the first portion (first mounting portion 117) and the second portion (second mounting portion 116) are located on different steps. This embodiment can also be understood as the first portion (first mounting portion 117) is located on a first plane (no reference numeral), the second portion (second mounting portion 116) extends on a second plane (no reference numeral), the first plane and the second plane are perpendicular to the optical axis of the lens module 101, and the distance between the intersection of the first plane and the second plane with the optical axis is greater than zero. In summary, this structural design can create additional space to accommodate the first driving magnet 121, the third driving magnet 126, and the third driving coil 125 without increasing the thickness, and the thickness of the entire lens device 100 can be reduced compared to the prior art. It can be understood that in this embodiment, a step or stair-like structure is formed on the base 110 or the flexible circuit board 119, but the present invention is not limited thereto. In another embodiment, the step or stair-like structure can be provided on the bottom of the second carrier 114, and the relative arrangement of the driving device 107 can be adjusted accordingly. For example, the driving coil is installed on the bottom of the second carrier 114, and the driving magnet is installed on the base 110, which also achieves the effect of increasing the space utilization rate and reducing the thickness compared to the prior art. In other words, the driving coil is installed on one of the base or the second carrier, and the driving magnet is installed on the other of the base or the second carrier.

[0029] Although preferred embodiments of the present invention have been disclosed as described above, these are by no means intended to limit the present invention, and anyone familiar with the art may make various modifications thereto without departing from the spirit of the present invention.
