Detailed Description

The optical system of the embodiment of the present invention is explained below. It should be appreciated, however, that the present embodiments provide many suitable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments disclosed are merely illustrative of specific ways to make and use the invention, and do not delimit the scope of the invention.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

Fig. 1 is a schematic diagram of an optical system 1 according to an embodiment of the present invention. The optical system 1 is, for example, a system capable of driving and carrying dual optical elements (e.g., dual lenses), and can be disposed inside an electronic device (e.g., a camera, a tablet computer, or a mobile phone), and mainly includes a first optical module 10, a second optical module 20, and an optical path adjusting mechanism 30, where the optical path adjusting mechanism 30 is disposed between the first and second optical modules 10, 20 (in the Y-axis direction). The optical path adjusting mechanism 30 is used for guiding an incident light to the second optical module 20. As shown in fig. 1, when light (incident light) from the outside enters the optical system 1, the incident light Q1 (Z-axis direction) passes through a first optical element (e.g., a lens, not shown) disposed in the first optical module 10 and reaches a photosensitive element (not shown) disposed on the electronic device; and the incident light Q2 (Z-axis direction) passes through an optical path adjusting unit P (e.g. prism, mirror) of the optical path adjusting mechanism 30, and is reflected to enter the second optical module 20 along the Y-axis direction, so that the light can pass through a second optical component (e.g. lens) L of the second optical module 20 and reach the photosensitive component in the electronic device to obtain an image.

It should be noted that the second optical axis O2 (substantially parallel to the Y axis) of the second optical element L of the second optical module 20 is substantially perpendicular to the incident direction of the incident light Q1, Q2 (and the first optical axis O1 of the first optical element), and the components of the second optical module 20 can be disposed along the direction parallel to the Y axis, so that the thickness of the electronic device in the Z axis direction can be greatly reduced, thereby achieving miniaturization.

The first Optical element and the second Optical element L can move relative to the photosensitive element in the electronic device, and further can properly adjust the focal length thereof, so as to achieve the effect of Auto-Focusing (AF) or Optical Image Stabilization (OIS), and further, by configuring the Optical path adjusting mechanism 30 to adjust or correct the angle of light incident into the second Optical element L, the Image quality can be greatly improved. The structures and arrangements of the first and second

optical modules

10 and 20 and the optical path adjusting mechanism 30 will be described in detail below.

The structure of the first optical module 10 will be described first. Referring to fig. 1 and fig. 2A together, fig. 2A is an exploded view of the first optical module 10 in fig. 1. The first optical module 10 mainly includes: a base 11, a carrier 12, an upper spring 13, a lower spring 14, an outer frame 15 (made of plastic), and a first electromagnetic driving component MC 1. The carrier 12 carries a first optical component (not shown), for example, a carrying groove disposed on the carrier 12, and the carrier 12 is movably connected to the base 11 and the outer frame 15 through upper and lower springs (for example, leaf springs) 13 and 14. The first electromagnetic driving component MC1 includes a first coil C1 (or coil component) and a plurality of first magnetic components M1 (such as magnets) configured to drive the carrier 12 and the first optical component located therein to move relative to the base 11, so as to achieve the purpose of auto-focusing or optical anti-shake. The first coil C1 is disposed on the carrier 12, and the first magnetic element M1 is disposed on the base 11 and surrounding the carrier 12, and faces the first coil C1. A driving signal (e.g., a driving current) is applied to the first coil C1 by an external power source (not shown), so as to generate a magnetic force between the first magnetic assembly M1 and the carrier 12, thereby moving the carrier 12 relative to the base 11. In addition, the upper and

lower springs

13, 14 can hold the carrier 12 in an initial position relative to the base 11 before the driving signal is applied. The first electromagnetic driving component MC1 is a moving coil type in the present embodiment, and can be a moving magnet type in another embodiment.

The mechanism and arrangement of the second optical module 20 and the optical path adjusting mechanism 30 will be described below. Referring to fig. 1 and fig. 2B together, fig. 2B is an exploded view of the second optical module 20 and the optical path adjusting mechanism 30 in fig. 1. The second optical module 20 mainly includes: the second optical assembly L, the base 21, the carrier 22 and the frame 26, wherein the carrier 22 carries the second optical assembly L and is disposed on the base 21 and in the frame 26, and the base 21 is connected and fixed with the frame 26. In some embodiments, the second optical module 20 may be configured with a connection component B and a third electromagnetic driving component MC3 between the base 21 and the carrier 22, as shown in fig. 2B, the connection component B is, for example, a rolling component, and the carrier 22 is movably connected to the base 21, the third electromagnetic driving component MC3 includes a plurality of third coils C3 (or coil components) and a plurality of third magnetic components M3, and by applying a driving signal (for example, a driving current), the third electromagnetic driving component MC3 can drive the carrier 22 and the second optical component L to move (for example, move on the XY plane) relative to the base 21 and the frame 26, so as to achieve the effects of focusing and preventing hand shock.

With reference to fig. 1 and fig. 2B, the aforementioned optical path adjusting mechanism 30 is used to introduce the incident light Q2 into the second optical element L, and mainly includes: the optical path adjusting unit P, a base 31, a supporting member 32, an elastic component 33, a circuit board member F and a second electromagnetic driving component MC 2. Referring to fig. 2B and 3, fig. 3 is a schematic view of the optical path adjusting mechanism 30. The base 31 and the carrier 32 are substantially triangular prism shaped, and the carrier 32 is disposed in the receiving cavity 310 of the base 31 and movably connected to each other by an elastic member (e.g. a spring) 33. In detail, the base 31 and the carrier 32 have inclined

surfaces

311 and 321, respectively, and the elastic element 33 is disposed on the two

inclined surfaces

311 and 321 to connect the base 31 and the carrier 32. The optical path adjusting unit P is also substantially triangular prism-shaped, and the supporting member 32 supports the optical path adjusting unit P (the two are fixed to each other), and in detail, the optical path adjusting unit P is disposed on the

inclined surfaces

311 and 321, wherein the elastic component 33 is interposed between the optical path adjusting unit P and the base 31 and the supporting member 32.

Fig. 4 is a schematic diagram showing the optical path adjustment mechanism 30 with the circuit board member F separated from the base 31. The second electromagnetic driving component MC2 is disposed at the bottom side of the base 31 and the supporting component 32, and specifically, the second electromagnetic driving component MC2 includes a second coil C2 (or called coil component) and a second magnetic component M2, which are corresponding to each other and respectively disposed on the circuit board member F and the bottom surface 322 of the supporting component 32, the second coil C2 and the circuit board member F are fixed to each other, and the second magnetic component M2 and the supporting component 32 are fixed to each other (also fixed to the optical path adjusting unit P). The circuit board member F is disposed on the bottom surface 312 of the base 31, as shown in fig. 4, a groove 312A is formed on the bottom surface 312, and can receive the circuit board member F and fix it with the base 31. When a driving signal is applied to the second coil C2 (for example, an external power supply applies a signal through the circuit board member F), the magnetic force generated between the second coil C2 and the magnetic element M2 causes the supporting element 32 and the optical path adjusting unit P to move together relative to the base 31, so as to adjust the incident angle at which the optical path adjusting unit P guides the incident light Q2 to the second optical element P, thereby achieving the optical anti-shake effect.

It should be noted that the optical path adjusting unit P and the second electromagnetic driving element MC2 are arranged along the Z-axis direction (the incident direction of the incident light Q2), and the second magnetic element M2 and the second coil C2 are also disposed up and down along the Z-axis direction. In one embodiment, the second magnetic element M2 is, for example, a multi-pole magnet, and the magnetic force is more closed and circulates than a single-pole magnet, thereby reducing the magnetic interference problem caused by other circuit elements of the optical system 1. In one embodiment, the second magnetic element M2 may be a combination of two single-pole magnets.

Fig. 5 shows the arrangement of the first magnetic block M1 (belonging to the first optical module 10) of the first electromagnetic drive block MC1 and the second magnetic block M2 (belonging to the optical path adjustment mechanism 30) of the second electromagnetic drive block MC 2. As shown, the magnetic pole of the first magnetic element M1 is oriented along the X or Y axis (perpendicular to the first optical axis O1), and the magnetic pole of the second magnetic element M2 is oriented along the Z axis (parallel to the first optical axis O1 or the incident direction of the incident light Q2), and the two magnetic elements are not parallel, and in one embodiment, the two magnetic elements are perpendicular to each other. Therefore, compared to the way that the first and second magnetic elements M1, M2 are arranged in parallel (the magnetic poles are in the same direction or along the same axis), the present embodiment can effectively reduce the degree of magnetic interference between the two magnetic elements by changing the arrangement positions of the magnetic elements (M1, M2), so as to improve the quality of the whole system. In addition, the first and second magnetic assemblies M1 and M2 do not overlap (i.e., the two magnetic assemblies are at different heights in the Z-axis direction) when viewed in the direction perpendicular to the first optical axis O1 (i.e., the Y-axis direction), thereby reducing or avoiding the problem of mutual electromagnetic interference caused by being along the same plane. In this way, when the magnetic interference is greatly reduced, the optical path adjusting mechanism 30 is disposed closer to the first optical module 10, and the distance D1 (shown in fig. 1) between the two can be further reduced, so that the volume of the optical system 1 in the electronic device is reduced, and the electronic device is miniaturized.

In addition, the optical path adjusting unit P of the present embodiment further includes a magnetic conductive element (permeability element) T and a pair of bit elements U, as shown in fig. 3 and 4. The magnetic conductive component T is disposed between the light path adjusting unit P and the second electromagnetic driving component MC2, and more specifically, between the bottom surface 321 and the second magnetic component M2, so as to concentrate the magnetic force of the second magnetic component M2 in a predetermined direction, so as to enhance the magnetic thrust for driving the supporting component 32 to move and reduce the magnetic interference. In an embodiment, the bottom 321 of the supporting element 32 corresponding to the second magnetic element M2 may be embedded with the magnetic conductive element T to make it have a magnetic conductive material, and the second magnetic element M2 is directly contacted and fixed on the bottom 321, so as to enhance the magnetic force (between the second magnetic element M2 and the second coil C2) in a predetermined direction, and further enhance the overall mechanical strength of the supporting element 32.

The alignment element U is, for example, a position Sensor, such as a Magnetoresistive Sensor (MRS) or an Optical Sensor (Optical Sensor), which is used to sense the position relationship between the carrier 32 and the light path adjusting unit P relative to the base 10, so that a control unit (not shown) can adjust the position therebetween through the second electromagnetic driving element MC 2. It should be noted that the alignment element U is disposed in the hollow portion of the second coil C2 (in other words, the alignment element U is surrounded by the second coil C2), which allows the overall mechanism to be miniaturized. In the present embodiment, the alignment element U and the second coil C2 share the second magnetic element M2.

Fig. 6A is a schematic view of the elastic member 33. The elastic component 33 is disposed on the base 31 and the carrier 32, and is located between the optical path adjusting unit P and the carrier 32 (fig. 2B). Before the driving signal is applied, the elastic component 33 can keep the carrier 32 and the optical path adjusting unit P at an initial position relative to the base 31. It should be noted that the elastic element 33 has a fixed portion 331 and a movable portion 332 (respectively connecting the base 31 and the supporting element 32), taking the left half of the elastic element 33 as an example, the fixed portion 331 has two first string-out ends S1, and the movable portion has two second string-out ends S2, wherein the connection distance between the two first string-out ends S1 is greater than the connection distance between the two second string-out ends S2, so as to enhance the strength of the elastic element 33 fixed on the base 31 and also provide the supporting element 32 with proper mobility (relative to the base 31). In addition, the elastic element 33 further includes a connecting portion 333 substantially perpendicular to the incident direction of the incident light Q2 and having a narrow section R1, as seen in fig. 6B, the width of the narrow section R1 is smaller than the width of the connecting portion 333 (Junction) R2 and R3 at the connection between the fixed portion 331 and the movable portion 332. In other words, the connection points R2 and R3 and the narrow portion R1 have a step difference in width, so that the elastic element 33 has a better stress dispersion effect, and the quality of the device is improved.

Fig. 7 shows another embodiment of the second electromagnetic driving assembly MC2a, and the second electromagnetic driving assembly MC2a in this embodiment is mainly different from the second electromagnetic driving assembly MC2 in that: the second electromagnetic driving component MC2a has a plurality of (two) second coils C2a corresponding to the second magnetic component M2, and the alignment component U is disposed between the two second coils C2 a. Since the alignment unit U is no longer disposed in the hollow position inside the coil, the thickness W (Y-axis direction) of the second coil C2a can be smaller than that of the second coil C2 of embodiment 1. In addition, the two second coils C2a of the present embodiment are electrically independent, and can be independently applied with driving signals, and the external power supply applies a plurality of different driving signals to the second coil C2a, so that the second coil C2a is independently controlled, and generates magnetic forces with the same or different directions and magnitudes as the second magnetic element M2. For example, when driving signals with the same magnitude and direction are input to the two second coils C2a and a magnetic force is generated between the two second coils C2a and the second magnetic element M2, the carrier 32 and the optical path adjusting unit P can be rotated in the X-axis direction relative to the base 31; when driving signals with the same magnitude and different directions are input, the carrier 32 and the optical path adjusting unit P can be rotated in the Z-axis direction relative to the base 31. In this way, the bearing 32 and the optical path adjusting unit P can rotate in different axial directions.

Fig. 8 shows a schematic diagram of a circuit board member F ', an alignment assembly U, U', and a second electromagnetic driving assembly MC2 according to another embodiment. The circuit board member F ' in this embodiment can define a body plate F1 ' and an additional circuit board F2 ', the additional circuit board F2 ' being inclined with respect to the body plate F1 '. The second coil C2 is disposed on the body plate F1 ', and the alignment component U is disposed on the additional circuit board F2' instead of being disposed in the hollow portion of the second coil C2. The main board F1 'is perpendicular (or substantially perpendicular) to the incident direction of the incident light Q2 or the magnetic pole direction (Z axis) of the second magnetic element M2, and the additional circuit board F2' has an oblique angle with respect to the incident direction of the incident light Q2 or the magnetic pole direction (Z axis) of the second magnetic element M2. The aforementioned alignment component U corresponds to another alignment component U' (can be disposed on the carrier 32), and both components can constitute an alignment component. By arranging the alignment component U, U' to have an angle inclination with respect to the magnetic pole direction of the second magnetic component M2 and no longer share the second magnetic component M2 with the second coil C2, the driving force of the second electromagnetic driving component MC2 can be reduced, and the accuracy of the relative position between the sensing carrier 32 (and the optical path adjusting unit P carried by the sensing carrier) and the base 31 can be improved.

In summary, the present invention provides an optical system, which can be disposed in an electronic device, and includes a first optical module, a second optical module, and an optical path adjusting mechanism. The first optical module and the second optical module are respectively used for bearing a first optical component and a second optical component, the first optical component and the second optical component are respectively provided with a first optical axis and a second optical axis which are vertical to each other, and the first optical module is provided with a first electromagnetic driving component. The optical path adjusting mechanism is arranged between the first optical module and the second optical module, guides an incident light to the second optical module, and comprises an optical path adjusting unit and a second electromagnetic driving component, wherein the optical path adjusting unit and the second electromagnetic driving component are arranged along the incident direction of the incident light. In addition, the first electromagnetic driving component and the second electromagnetic driving component are respectively provided with a first magnetic component and a second magnetic component, and the magnetic pole directions of the first magnetic component and the second magnetic component are not parallel. Therefore, through the configuration, the two electromagnetic driving components in the optical system can reduce the mutual interference, not only can the magnetic thrust be effectively improved, but also the optical path adjusting mechanism and the second optical module can be arranged closer to the first optical module (under the condition of reducing the magnetic interference), so that the whole volume of the mirror optical system can be reduced, and the miniaturization can be realized. Furthermore, the light path adjusting unit and the second electromagnetic driving component are arranged along the incident direction of the incident light, so that other components of the electronic device can be elastically arranged.

Ordinal numbers such as "first," "second," etc., in the specification and claims are not necessarily consecutive to each other, but are merely used to identify two different elements having the same name.

The embodiments described above are described in sufficient detail to enable those skilled in the art to practice the disclosed apparatus, and it is to be understood that various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
