[0083] This disclosure provides an imaging lens module including an optical reversing element and a driving module, wherein the driving module is used to rotate the optical reversing element. The optical reversing element has a reflective surface. A light ray is incident on the optical reversing element along a first optical axis, reflected by the reflective surface, and exits the optical reversing element along a second optical axis. The first and second optical axes intersect at a point on the reflective surface. The driving module includes a first carrier, a first magnet, at least two first ball bearings, a second carrier, and a second ball bearing. The first carrier is disposed on a frame and is rotatable relative to the frame around a first rotation axis, which is perpendicular to the first optical axis and passes through the point of intersection. The first magnet generates a driving force with a first coil, driving the first carrier. The first ball bearing is disposed between the frame and the first carrier to support the rotation of the first carrier. The second carrier is disposed on the first carrier, and the optical reversing element is disposed on the second carrier. The second ball bearing is disposed between the first and second carriers to support the rotation of the second carrier. The second carrier rotates relative to the first carrier around a second rotation axis, which is perpendicular to the first rotation axis. In this way, the first carrier can be pitched, and the second carrier can be yawed relative to the first carrier, giving the optical switching element two degrees of freedom of rotation.

[0084] Since the first carrier simultaneously supports the second carrier and the optical deflector, it has a high load. A 1-degree pitch rotation of the reflective surface around the first rotation axis causes a 2-degree deflection of the optical axis. Therefore, the pitch rotation performed by the heavily loaded first carrier can reduce the rotation angle compared to yaw rotation, thereby achieving energy savings. Specifically, the intersection point of the optical axes of the first and second carriers serves as the center of rotation.

[0085] The intersection point of the first ball bearing element and the optical axis can be coaxially arranged along the first rotation axis. This ensures that the position of the intersection point remains unchanged during pitch rotation of the drive module, helping to reduce the difficulty of drive control.

[0086] The intersection point of the second ball bearing element and the optical axis can be coaxially arranged along the second rotation axis. This ensures that the position of the intersection point remains unchanged during the yaw rotation of the drive module, helping to reduce the difficulty of drive control.

[0087] Viewed along the first axis of rotation, the first ball element and the first magnet are positioned along the second axis of rotation. This allows the driving force of the first magnet to effectively generate rotational torque.

[0088] The drive module may further include a first magnetic attracting element. The first magnetic attracting element is fixed to the frame and correspondingly positioned with respect to a first magnet. The first magnetic attracting element and the first magnet attract each other to provide a preload force to the first carrier. Viewed along the first rotation axis, the first ball element, the first magnet, and the first magnetic attracting element are sequentially arranged along the second rotation axis. Thus, the first magnet simultaneously provides both driving force and assembly preload force. Furthermore, the first magnet and the first magnetic attracting element are arranged along the first optical axis, which helps to prevent the preload force from generating torque, allowing the first carrier to maintain a stable posture when not powered. Specifically, the preload force is the assembly bonding force between the first carrier and the frame, ensuring that the first carrier and the frame remain in a bonded state.

[0089] Viewed along the first axis of rotation, the first ball element, the second ball element, and the first magnet can be sequentially arranged along the second axis of rotation. This helps the drive module maintain a stable posture.

[0090] Viewed along the first axis of rotation, the first ball element is farther away from the first magnet relative to the second ball element. This gives the first magnet a longer driving arm.

[0091] The drive module may further include at least two third ball bearing elements, which are disposed between the first carrier and the second carrier to support the rotation of the second carrier, and are arranged around the second ball bearing element as the center. This assists in the rotation of the second carrier and helps improve rotational stability.

[0092] Each third ball bearing element can have two-point contact with the second carrier. This avoids over-positioning that could affect rotational accuracy.

[0093] Each third ball bearing element can have three-point contact with the first carrier. This allows for a balance between positioning and rotational accuracy.

[0094] The distance between the first, second, and third ball elements can be fixed. This helps maintain the structural stability of the drive module during the drive process.

[0095] The drive module may also include a second magnet for driving the second carrier to rotate, wherein the second magnet has four poles. This helps to improve the stability of the magnetic field.

[0096] The second magnet can be arc-shaped, with the first rotation axis as its center. This helps maintain the magnetic field distribution between the second magnet and the second coil after the first carrier rotates, thereby improving the stability of the driving force.

[0097] The drive module may further include a second magnetic element disposed on the second carrier and attracting the first magnet to provide a preload force to the second carrier. Thus, the first magnet, in addition to providing the driving force for the first carrier, also provides the function of providing the assembly preload force between the first and second carriers.

[0098] Alternatively, a second magnetic element is disposed on the second carrier and attracts a third magnet to provide a preload force to the second carrier. This allows the second carrier to remain in a coupled state with the first carrier.

[0099] The second magnetic element can be disposed inside the second carrier. This saves space and helps to improve the structural strength of the second carrier. Specifically, the second magnetic element can be embedded inside the second carrier by embedding and ejection, but this disclosure is not limited thereto.

[0100] The imaging lens module may also include a lens group disposed on the frame and movable relative to the frame along a second optical axis. This allows the frame to simultaneously house the drive module and the lens group, helping to reduce assembly procedures.

[0101] The imaging lens module may also include at least two fourth ball bearing elements for supporting the movement of the lens group. This enables the lens group to have focusing or zooming capabilities.

[0102] This disclosure provides an electronic device that includes the aforementioned imaging lens module.

Figures 1A to 1CAs can be seen, the imaging lens module 100 includes a frame 101, an optical reversing element 110, a lens group 120, a driving module (not otherwise indicated), and a photosensitive element 102. The optical reversing element 110, the lens group 120, and the photosensitive element 102 are disposed on the frame 101 from the object side to the image side of the imaging lens module 100. The driving module is disposed on the frame 101 and is used to rotate the optical reversing element 110. The optical reversing element 110 has a reflecting surface 111. A ray of light enters the optical reversing element 110 along a first optical axis X1, is reflected by the reflecting surface 111, and exits the optical reversing element 110 along a second optical axis X2. The first optical axis X1 and the second optical axis X2 intersect at an optical axis intersection point IP on the reflecting surface 111. After entering the optical reversing element 110 along the first optical axis X1, the ray is reversed by the reflecting surface 111 and passes through the lens group 120 along the second optical axis X2 before entering the photosensitive element 102.

Figure 1E Drawing according to Figure 1A Another exploded view of the drive module, optical transition element 110, and frame 101 of the first embodiment. Figures 1B to 1D It is understood that the drive module includes a first carrier 131, a first magnet 141, two first ball bearing elements 151, a second carrier 132, and a second ball bearing element 152. The first carrier 131 is disposed on the frame 101, the second carrier 132 is disposed on the first carrier 131, and the optical deflection element 110 is disposed on the second carrier 132. The first magnet 141 is disposed on the frame 101, and the first ball bearing element 151 is disposed between the frame 101 and the first carrier 131.

[0106] Please refer to the following: Figure 1F , Figure 1G as well as Figure 1H ,in Figure 1F Drawing according to Figure 1A A schematic diagram of the first carrier 131 rotating around the first rotation axis R1 in the first embodiment. Figure 1G Drawing according to Figure 1F sectional view, Figure 1HA schematic diagram is shown, viewed along the first rotation axis R1, comprising the first ball element 151, the second ball element 152, the first magnet 141, and the first magnetizing element 171. The first carrier 131 can pitch and rotate relative to the frame 101 about the first rotation axis R1, thus causing the optical deflection element 110 to rotate about the first rotation axis R1. The first rotation axis R1 is perpendicular to the first optical axis X1 and passes through the intersection point IP of the optical axes. The first magnet 141 generates a driving force with the first coil 161, driving the first carrier 131. The first ball element 151 supports the rotation of the first carrier 131.

[0107] The drive module may further include a first magnetic element 171, which is fixed to the frame 101 and correspondingly arranged with the first magnet 141. The first magnetic element 171 and the first magnet 141 attract each other to provide a preload force for the first carrier 131.

[0108] Reference Figure 1I , Figure 1J as well as Figure 1K ,in Figure 1I Drawing according to Figure 1F Another sectional view, Figure 1J Drawing according to Figure 1A A schematic diagram of the second carrier 132 rotating around the second rotation axis R2 in the first embodiment. Figure 1K Drawing according to Figure 1J A cross-sectional view. The second carrier 132 oscillates relative to the first carrier 131 about the second rotation axis R2 (i.e., the first optical axis X1), thus causing the optical deflection element 110 to rotate about the second rotation axis R2, wherein the second rotation axis R2 is perpendicular to the first rotation axis R1. The second ball bearing element 152 is disposed between the first carrier 131 and the second carrier 132 to support the rotation of the second carrier 132.

[0109] The drive module may further include two second magnets 142, which are disposed on both sides of the second carrier 132 and respectively opposite to the second coils 162 disposed on the frame 101, for driving the second carrier 132 to rotate. (See reference) Figure 1L Its drawing is based on Figure 1A A schematic diagram of the second magnet 142 in the first embodiment. Figure 1L It can be seen that the second magnet 142 has four polarities 142a, 142b, 142c, and 142d. The adjacent polarities 142a, 142b, 142c, and 142d are different to form the second magnet 142.

[0110] Depend on Figure 1H as well as Figure 1IAs can be seen, when viewed along the first rotation axis R1, the first ball element 151, the second ball element 152, and the first magnet 141 are arranged sequentially along a direction parallel to the first optical axis X1 (i.e., parallel to the second rotation axis R2), and the first ball element 151 is farther away from the first magnet 141 relative to the second ball element 152. The intersection point IP of the first ball element 151 and the optical axis is coaxially arranged along the first rotation axis R1. The intersection point IP of the second ball element 152 and the optical axis is coaxially arranged along the second rotation axis R2.

[0111] Reference Figure 1M as well as Figure 1N ,in Figure 1M Drawing according to Figure 1K A schematic diagram of the contact point 1531 between the first carrier 131 and the third ball element 153. Figure 1N Drawing according to Figure 1A A schematic diagram of the second magnetic element 172 and the third magnet 143 in the first embodiment. The drive module may further include two third ball bearing elements 153, the second magnetic element 172, and the third magnet 143. The third ball bearing element 153 is disposed between the first carrier 131 and the second carrier 132 to support the rotation of the second carrier 132, and the third ball bearing element 153 is arranged around the second ball bearing element 152 as the center. The second magnetic element 172 is disposed on the second carrier 132 and attracts the third magnet 143 disposed on the first carrier 131 to provide a preload force for the second carrier 132. Accordingly, the second carrier 132 can be assembled and combined with the first carrier 131 by the attraction between the second magnetic element 172 and the third magnet 143. Specifically, the second magnetic element 172 is disposed inside the second carrier 132, and Figure 1N In the first embodiment, the second magnetic element 172 is embedded inside the second carrier 132 by embedding and ejection, but the content of this disclosure is not limited thereto.

[0112] In addition, by Figure 1K as well as Figure 1M It can be seen that each third ball element 153 has three-point contact with the first carrier 131 (i.e., has three contact points 1531), and each third ball element 153 has two-point contact with the second carrier 132 (i.e., has two contact points 1532).

[0113] Furthermore, by Figure 1C It is understood that the imaging lens module 100 may also include a fourth ball bearing element 154, which is disposed between the lens group 120 and the frame 101 to support the movement of the lens group 120.

[0114] <Second Embodiment>

[0115] Please refer to Figures 2A to 2C ,in Figure 2AAn exploded view of the driving module (not shown), optical transition element 110, and frame 101 of the imaging lens module (not shown) according to the second embodiment of this disclosure is shown. Figure 2B Drawing according to Figure 2A A three-dimensional diagram of the second magnet 242 in the middle. Figure 2C Drawing according to Figure 2A A schematic diagram of the second coil 162, the second magnet 242, and the first rotating shaft R1 of the imaging lens module.

[0116] Depend on Figures 2A to 2C As can be seen, the main difference between the imaging lens module of the second embodiment and the imaging lens module 100 of the first embodiment is that the second magnet 242 of the second embodiment is different from the second magnet 142 of the first embodiment. Specifically, in the second embodiment, the second magnet 242 is arc-shaped, with the first rotation axis R1 as its center. Because the second magnet 242 is arc-shaped with the first rotation axis R1 as its center, the second magnet 242 can maintain the magnetic field distribution with the second coil 162 after pitch rotation. Figure 2B It can be seen that the second magnet 242 has four polarities 242a, 242b, 242c, and 242d. The adjacent polarities 242a, 242b, 242c, and 242d are different to form the second magnet 242.

[0117] It must be noted that the shape and configuration of other components in the second embodiment are the same as or similar to those in the first embodiment. Figure 2A and Figure 2C In this embodiment, elements that are the same as or similar to those in the first embodiment are indicated by the same reference numerals, and their connections and actuation relationships will not be described again.

Figure 3 As can be seen, the main difference between the imaging lens module of the third embodiment and the imaging lens module 100 of the first embodiment is that the second carrier 332 of the third embodiment attracts the first magnet 341 disposed on the first carrier 331 through the second magnetizing element 372 disposed therein to provide preload force for the second carrier 332, thereby making the second carrier 332 and the first carrier 331 combine.

[0120] Specifically, the second magnetic element 372 is embedded inside the second carrier 332 by means of embedding and ejection, but the content of this disclosure is not limited thereto.

[0121] It should be noted that the shape and configuration of other components in the third embodiment are the same as or similar to those in the first embodiment, and their connection and operation relationship will not be described again.

[0122] <Fourth Embodiment>

[0123] Please refer to Figure 4A and Figure 4B ,in Figure 4A A schematic diagram of the electronic device 400 according to the fourth embodiment of this disclosure is shown. Figure 4B Drawing according to Figure 4A Another schematic diagram of the electronic device 400 in the fourth embodiment. Figure 4A and Figure 4B As can be seen, the electronic device 400 is a smartphone. The electronic device 400 includes multiple camera modules and a user interface 401. Each camera module may include an imaging lens module of any of the aforementioned first to third embodiments, but the present disclosure is not limited thereto. Furthermore, the camera modules are a high-pixel camera module 410, an ultra-wide-angle camera module 420, and dual telephoto camera modules 430 and 440, and the user interface 401 is a touch screen, but is not limited thereto.

[0124] The user enters the shooting mode through the user interface 401, which displays the screen and allows manual adjustment of the shooting angle to switch between different camera modules. At this time, the camera module focuses the imaging light onto the electronic image sensor and outputs electronic signals related to the image to the image signal processor (ISP) 450.

[0125] Depend on Figure 4AAs can be seen, depending on the camera specifications of the electronic device 400, the electronic device 400 may also include an optical image stabilization component (not shown in the figure). Furthermore, the electronic device 400 may also include at least one focus assist module (not shown in the figure) and at least one sensing element (not shown in the figure). The focus assist module may be a color temperature compensated flash module, an infrared rangefinder, a laser focus module, etc. The sensing element may have the function of sensing physical momentum and kinetic energy, such as an accelerometer, a gyroscope, or a Hall effect element, to sense the shaking and tremors caused by the user's hand or the external environment. This is beneficial to the autofocus function and optical image stabilization component configured in the camera module of the electronic device 400, so as to obtain good image quality and help the electronic device 400 according to the present disclosure to have multiple shooting modes, such as optimized Selfie, low light HDR (High Dynamic Range) imaging, and high resolution 4K video recording. In addition, users can directly view the camera's shooting screen through the user interface 401 and manually operate the framing range on the user interface 401 to achieve the WYSIWYG autofocus function.

[0126] Furthermore, the camera module, optical image stabilization component, sensing element, and focus assist module can be mounted on a flexible printed circuit board (FPC) (not shown), and electrically connected to the imaging signal processing element 450 and other related components via a connector (not shown) to execute the shooting process. Current electronic devices, such as smartphones, tend to be thinner and lighter.

This also allows for more flexible control of the camera module's autofocus function through the electronic device's touchscreen. In the fourth embodiment, the electronic device 400 may include multiple sensing elements and multiple focus assist modules. The sensing elements and focus assist modules are mounted on a flexible printed circuit board and at least one other flexible printed circuit board (not shown), and electrically connected to the imaging signal processing element 450 and other related components via corresponding connectors to execute the shooting process. In other embodiments (not shown), the sensing element and auxiliary optical element may also be mounted on the motherboard of the electronic device or other types of carrier boards, depending on the mechanical design and circuit layout requirements.
