Description

Technical Field

[0001] This application relates to the field of autofocus technology, and in particular to a camera module and electronic device. Background Technology

[0002] In related technologies, the camera module inside electronic devices achieves focusing through AF (Auto Focus). It typically uses Hall effect sensors to measure changes in the magnetic flux density of moving parts to detect changes in the position of the camera module lens, thereby completing the closed-loop focusing function.

[0003] However, Hall devices require Hall magnets to be placed in corresponding positions when they are working, which leads to an increase in the number of magnets in the camera module. In multi-camera scenarios, the magnetic interference problem between adjacent camera modules needs to be considered. The presence of Hall magnets is not conducive to solving the magnetic interference problem and limits the design freedom of electronic devices in multi-camera scenarios. Summary of the Invention

When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0047] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the appendix. Figure 1The orientations or positional relationships shown are for the purpose of facilitating and simplifying the description of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0048] It should be understood that in this application, "electrical connection" can be understood as physical contact and electrical conduction between components; it can also be understood as a form of connection between different components in a circuit structure through physical lines that can transmit electrical signals, such as copper foil or wires on a printed circuit board (PCB). "Communication connection" can refer to the transmission of electrical signals, including wireless communication connections and wired communication connections. Wireless communication connections do not require a physical medium and are not a connection relationship that limits the product structure. "Connection" and "connected" can both refer to a mechanical or physical connection relationship, that is, A and B being connected or connected can mean that there are fastening components (such as screws, bolts, rivets, etc.) between A and B, or that A and B are in contact with each other and are difficult to separate.

[0049] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0050] A Hall effect device is a solid-state electronic device that utilizes the Hall effect. It uses a magnetic field as its working medium to convert the motion parameters of an object into a digital voltage output, enabling it to perform sensing and switching functions.

[0051] Focal length, also known as focal length, is a measure in optical systems of the convergence or divergence of light; it refers to the distance from the center of the lens to the focal point where light converges. Focusing, also called focusing the light or focusing the image, is the process of adjusting the position of the camera's focusing mechanism to make the subject appear sharp.

[0052] In the camera modules of mobile phones and other electronic devices, in order to make the image of the subject clear, it is necessary to adjust the distance between the lens and the photosensitive element. However, the camera module cannot be manually adjusted like a digital camera. It can only be automatically adjusted through structures such as voice coil motors. In order to achieve closed-loop focusing of the camera module, Hall effect devices are usually used to measure the change in magnetic induction intensity of the moving parts to detect the change in the position of the camera module lens, thereby completing the closed-loop focusing function.

[0053] However, since Hall devices require Hall magnets to be placed at corresponding positions to operate, this leads to an increase in the number of magnets in the camera module. In multi-camera scenarios, the magnetic interference problem between adjacent camera modules needs to be considered. The presence of Hall magnets is not conducive to solving the magnetic interference problem and limits the design freedom of electronic devices in multi-camera scenarios.

[0054] Therefore, this application provides a camera module that reduces the number of magnets in the camera module, so that the two sides of the camera module form a non-magnetic area, which is conducive to enriching the arrangement and combination of adjacent camera modules in multi-camera scenarios and improving the design freedom of electronic devices in multi-camera scenarios.

[0055] The electronic devices in this application embodiment can be mobile phones, tablets, laptops, smart bracelets, smartwatches, smart helmets, smart glasses, etc. Electronic devices can also be cellular phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), handheld devices with wireless communication capabilities, computing devices or other processing devices connected to a wireless modem, in-vehicle devices, electronic devices in 5G networks, or electronic devices in future evolved Public Land Mobile Networks (PLMNs), etc., and this application embodiment is not limited to these categories.

[0056] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0057] Combination Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a camera module. In some embodiments, the camera module includes: an actuator 1, an optical lens 2, and a photosensitive component 3.

[0058] The actuator 1 includes a mover part 11, a stator part 12, and a detection component 13.

[0059] The optical lens 2 is connected to the moving part 11, and the photosensitive component 3 is connected to the stator part 12. The moving part 11 and the stator part 12 are movably connected along the light path of the optical lens 2. The moving part 11 includes two drive coils 111, which are arranged along the first direction B. The stator part 12 includes two magnet components 121, which are arranged along the first direction B, and each magnet component 121 corresponds to one drive coil 111.

[0060] The detection component 13 includes at least one moving electrode 131 and at least one fixed electrode 132. The at least one moving electrode 131 is located on the side of the moving part 11 along the second direction C, and the at least one fixed electrode 132 is located on the side of the stator part 12 along the second direction C. The positions of the at least one moving electrode 131 and the at least one fixed electrode 132 are spaced apart from each other.

[0061] In this configuration, the first direction B and the second direction C are perpendicular to each other, and the first direction B and the second direction C are perpendicular to each other with respect to the ray path.

[0062] The camera module of this embodiment includes an actuator 1, an optical lens 2, and a photosensitive component 3. The optical lens 2 is connected to the moving part 11 of the actuator 1 and can move along the light path with the moving part 11 to achieve zooming of the camera module. The photosensitive component 3 is connected to the stator part 12 and receives the light entering through the optical lens 2 to perform imaging tasks. The detection component 13 includes a moving electrode 131 and a fixed electrode 132 arranged at relative intervals. The moving electrode 131 can move with the moving part 11 and the optical lens 2, thereby changing the relative position between the moving electrode 131 and the fixed electrode 132. The change in relative position will cause the facing area between the moving electrode 131 and the fixed electrode 132 to change. The change in facing area will cause the capacitance value between the moving electrode 131 and the fixed electrode 132 to change. By measuring the capacitance value between the moving electrode 131 and the fixed electrode 132, the position of the moving electrode 131, the moving part, and the optical lens 2 can be determined, thereby realizing closed-loop focusing of the camera module.

[0063] The detection component 13 has a simple structure and does not require magnetic components, which reduces the number of magnets in the camera module and makes the two sides of the camera module form a non-magnetic area. This is beneficial to enrich the arrangement and combination of adjacent camera modules in multi-camera scenarios and improves the design freedom of electronic devices in multi-camera scenarios.

[0064] Compared to Hall devices in related technologies, the detection component 13 in this embodiment does not require the arrangement of Hall magnets, which can reduce the number of magnets in the camera module and reduce magnetic interference in the camera module in multi-camera scenarios.

[0065] In multi-camera scenarios, electronic devices need to place camera modules on the non-magnetic side of adjacent camera modules to avoid magnetic interference. However, camera modules using Hall effect devices typically have only one non-magnetic side, which limits the number of possible permutations and combinations of adjacent camera modules.

[0066] In this embodiment, the camera module has drive coils 111 or magnet components 121 arranged on both sides along the first direction B, and no magnets or coils on both sides along the second direction C, so that the camera module has two non-magnetic sides. In multi-camera scenarios, the camera module can utilize the arrangement of adjacent camera modules on both sides along the second direction C, thereby enriching the number of arrangements of adjacent camera modules and improving the design freedom of electronic devices in multi-camera scenarios.

[0067] Combination Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, the axis of the drive coil 111 is arranged along a first direction B, thereby enabling the drive coil 111 to generate a coil magnetic field extending along the first direction B. This coil magnetic field interacts with the magnetic field generated by the magnet assembly 121, which is also arranged in the first direction B, thereby generating a force that drives the mover portion 11 to move along the light path.

[0068] Combination Figure 4 and Figure 5 As shown, in some embodiments, the magnet assembly 121 includes at least two magnet bodies 1211, which are arranged along the direction of the light path; the magnetic poles of the magnet bodies 1211 are arranged along a first direction B, and the magnetic poles of at least one magnet body 1211 are opposite to the magnetic poles of the other magnet bodies 1211.

[0069] With the above arrangement, the magnet component 121 can form at least two magnet magnetic fields in opposite directions in the light path. When the coil magnetic field generated by the drive coil 111 interacts with the at least two magnet magnetic fields, it can generate a repulsive force with the like magnetic field and an attractive force with the opposite magnetic field. By changing the direction or value of the current in the drive coil 111, the interaction force between the drive coil 111 and different magnet components 121 can be adjusted, thereby realizing the relative position adjustment of the mover part 11 and the stator part 12.

[0070] Combination Figure 4 and Figure 5 As shown, in some embodiments, the mover portion 11 further includes a carrier 112, with two drive coils 111 located on two outer sides of the carrier 112 along the first direction B.

[0071] The stator part 12 also includes a housing part 122, a carrier part 112 located inside the housing part 122, and two magnet components 121 located on two inner sides of the housing part 122 along the first direction B, and each magnet component 121 corresponds to a drive coil 111.

[0072] The moving part 11 in this embodiment includes a carrier 112 and a drive coil 111. The optical lens 2 is installed in the mounting hole 1121 of the carrier 112. The drive coil 111 is wound around the circumferential outer side of the carrier 112. When the drive coil 111 is energized, it can generate a magnetic force with the magnetic structure of the stator part 12, thereby pushing the carrier 112 to move along the light path A. The carrier 112 drives the optical lens 2 to move closer to or away from the photosensitive component 3 along the direction of the light path A, thereby realizing the focal length adjustment of the camera module.

[0073] In some possible implementations, the carrier 112 has a mounting hole 1121 in the middle for connecting the optical lens 2, and the housing 122 has a clearance hole 1221 in the middle for avoiding the optical lens 2. The axis of the mounting hole 1121 coincides with the light path A, and the axes of the mounting hole 1121 of the carrier 112 and the clearance hole 1221 of the housing 122 coincide. The top of the optical lens 2 extends to the outside of the stator portion 12 through the clearance hole 1221.

[0074] In some possible implementations, the carrier 112 has a winding portion 1122 on its outer side along the first direction B, and the drive coil 111 is wound and arranged on the winding portion 1122, thereby realizing a reliable connection between the drive coil 111 and the carrier 112.

[0075] Combination Figure 4 and Figure 5 As shown, in some embodiments, at least one moving electrode 131 is located on the outer side of the carrier member 112 along the second direction C, and at least one fixed electrode 132 is located on the inner side of the housing member 122 along the second direction C, and the positions of at least one moving electrode 131 and at least one fixed electrode 132 are spaced apart from each other.

[0076] In this embodiment, the movable electrode 131 is located on the outer surface of the carrier 112, opposite to the fixed electrode 132 of the stator portion 12. The movable electrode 131 moves with the carrier 112, changing the facing area between the movable electrode 131 and the fixed electrode 132. The facing area has a linear relationship with the capacitance value, thereby determining the relative position of the stator portion 12 and the movable portion 11 in the direction of the light path, thus realizing closed-loop focusing of the camera module.

[0077] Combination Figure 4 , 5 As shown, in some possible implementations, there are two fixed electrode plates 132, which are arranged at intervals on the inner side of the housing 122 along the direction of the light path A, and one moving electrode plate 131.

[0078] With the above arrangement, two fixed electrode plates 132 are spaced apart on the inner side of the housing 122 along the direction of the light path A. When the movable electrode plate 131 moves along the direction of the light path A, different parts of the movable electrode plate 131 can form two capacitor structures with the two fixed electrode plates 132 respectively. The detection unit 133 detects the capacitance value of the two capacitor structures respectively, which can more accurately determine the relative position of the movable electrode plate 131 and the fixed electrode plate 132, thereby improving the positional accuracy of the optical lens 2 and the focusing accuracy of the camera module.

[0079] Combination Figure 6As shown, in some embodiments, the detection component 13 further includes a detection unit 133, which is electrically connected to at least one moving electrode 131 and at least one fixed electrode 132 respectively; the detection unit 133 is used to detect the change in capacitance between at least one moving electrode 131 and at least one fixed electrode 132, and to determine the relative position of the moving part 11 and the stator part 12 based on the change in capacitance.

[0080] The formula for determining the capacitance is: C = εS / 4πkd (C is the capacitance value, ε is a constant, S is the area of ​​the capacitor plates facing each other, d is the distance between the capacitor plates, and k is the electrostatic constant). When the distance d between the capacitor plates is a constant, the capacitance value of the capacitor is only proportional to the area S facing each other. Therefore, the position change of the moving part 11 can be detected by the change in capacitance value caused by the change in the area facing each other.

[0081] In this embodiment, the moving electrode 131 simply moves along the light path with the moving part 11. The distance between the moving electrode 131 and the fixed electrode 132 is a constant, but the facing area of ​​the moving electrode 131 and the fixed electrode 132 changes with the degree of movement of the moving part 11. According to the formula for determining the capacitor, the facing area and the capacitance value are linearly related. The detection unit 133 is electrically connected to the moving electrode 131 and the fixed electrode 132 respectively. After detecting the capacitance value between the moving electrode 131 and the fixed electrode 132, the facing area between the moving electrode 131 and the fixed electrode 132 can be determined based on the capacitance value. Since the area of ​​the moving electrode 131 and the fixed electrode 132 is a regular shape (e.g., a square, a rectangle, etc.), the relative position of the moving electrode 131 and the fixed electrode 132 in the direction of the light path can be easily calculated. Thus, the relative position of the stator part 12 and the moving part 11 in the direction of the light path can be determined, thereby realizing the closed-loop focusing of the camera module.

[0082] In some possible implementations, the detection unit 133 is integrated into an integrated circuit that is electrically connected to the moving electrode 131 and the fixed electrode 132 respectively, applies a voltage between the moving electrode 131 and the fixed electrode 132, and determines the capacitance value between the moving electrode 131 and the fixed electrode 132 based on the voltage change.

[0083] Combination Figure 4 and Figure 5 As shown, in some embodiments, the actuator 1 further includes at least one elastic element 14, which is located at one end of the mover portion 11 along the light path and is connected between the mover portion 11 and the stator portion 12.

[0084] Optionally, the elastic element 14 includes an upper spring sheet 141 and a lower spring sheet 142. The upper spring sheet 141 is connected between the upper end of the carrier element 112 and the upper end of the housing element 122, and the lower spring sheet 142 is connected between the lower end of the carrier element 112 and the lower end of the housing element 122.

[0085] With the above arrangement, the moving part 11 is elastically and movably connected to the stator part 12 via the upper spring 141 and the lower spring 142. When the drive coil 111 is energized, the drive coil 111 generates a coil magnetic field. The coil magnetic field and the magnetic field generated by the magnet assembly 121 interact, and the drive coil 111 moves along the light path A. The optical lens 2 mounted on the carrier 112 moves together. When the drive coil 111 is de-energized, the moving part 11 returns under the elastic force of the upper spring 141 and the lower spring 142, thereby realizing the automatic focusing function of the camera module.

[0086] Combination Figure 2 As shown, in some embodiments, the photosensitive assembly 3 includes a circuit board 31 and a photosensitive element 32, the photosensitive element 32 being electrically connected to the circuit board 31, and the optical lens 2 being located on the photosensitive path of the photosensitive element 32.

[0087] The camera module in this embodiment is used to capture images or videos.

[0088] In some possible implementations, the photosensitive element 32, also known as an image sensor, can be a complementary metal-oxide-semiconductor (CMOS) or a charge-coupled device (CCD). It can also be other types of image sensors besides CMOS or CCD, such as a charge-injection device (CID) sensor.

[0089] Understandably, CMOS allows for the integration of digital signal processors (DSPs). CMOS offers advantages such as high integration density, low power consumption, and low cost, making it well-suited for electronic devices with limited installation space, such as mobile phones.

[0090] In some possible implementations, the surface of the circuit board 31 is provided with printed circuits, and the circuit board 31 includes a printed circuit board (PCB), a flexible printed circuit board (FPC), a rigid-flex board, etc.

[0091] In some possible implementations, the camera module may also include a flash. The flash can be a single-color temperature flash or a dual-color temperature flash. A dual-color temperature flash is a combination of a warm-light flash and a cool-light flash, which can be used for light compensation at different color temperatures.

[0092] In some embodiments, the camera module includes a front-facing camera and a rear-facing camera. Typically, the front-facing camera is located on the front panel of the electronic device, and the rear-facing camera is located on the back of the electronic device. Exemplarily, there are at least two rear-facing cameras, which are any one of a main camera, a depth-sensing camera, a wide-angle camera, and a telephoto camera, to achieve background blurring by merging the main camera and the depth-sensing camera, panoramic shooting by merging the main camera and the wide-angle camera, virtual reality (VR) shooting, or other fusion shooting functions.

[0093] Combination Figure 2 As shown, in some embodiments, the actuator 1 further includes a base portion 15, which is connected to the stator portion 12. The base portion 15 is connected to the lower end of the housing 122 of the stator portion 12, enclosing the mover portion 11 and thus integrating the actuator 1.

[0094] In this embodiment, the camera module is formed as two non-magnetic sides along the second direction. When other camera modules are arranged on these two non-magnetic sides, the two camera modules will not experience magnetic interference. (Refer to...) Figure 7 As shown, the camera module in this embodiment can be arbitrarily combined with the magnetic or non-magnetic sides of other camera modules using two non-magnetic sides, resulting in a wider range of arrangement and combination methods, which can improve the design freedom of electronic devices in multi-camera scenarios.

[0095] On the other hand, this embodiment provides an electronic device, which includes at least one camera module of this application.

[0096] The electronic device in this embodiment uses the camera module of this application and has all the beneficial technical effects of all embodiments herein.

[0097] In some possible implementations, the electronic device includes a motherboard.

[0098] In the camera module provided in this embodiment, during the shooting process, the imaging light of the object being photographed enters the optical lens and then reaches the photosensitive element 32. The photons in the imaging light hit the image sensor and generate movable charges. This is the internal photoelectric effect. The movable charges collect to form an electrical signal.

[0099] The aforementioned electrical signals are transmitted to the motherboard via a flexible circuit board. The motherboard houses an analog-to-digital converter (A / D converter) and a digital signal processor (DSP). The A / D converter converts the electrical signals into digital signals, which are then processed by the DSP. Finally, the images are displayed on the screen of the electronic device, thus enabling the photographing of the subject.

[0100] In some possible implementations, the terminal device may also include radio frequency (RF) circuitry, a memory including one or more computer-readable storage media, an input unit, a display unit, a sensor, an audio circuit, a Wi-Fi module, a processor including one or more processing cores, and a power supply, among other components.

[0101] The detection unit is electrically connected to the processor. The processor is the control center of the terminal device, connecting various parts of the phone via various interfaces and lines. It performs various functions and processes data by running or executing software programs and / or modules stored in the memory, and by calling data stored in the memory, thereby monitoring the phone as a whole. Optionally, the processor may include one or more processing cores; preferably, the processor may integrate an application processor and a modem processor, wherein the application processor mainly handles the operation of the storage medium, user interface, and applications, while the modem processor mainly handles wireless communication. It is understood that the modem processor may also not be integrated into the processor.

[0102] It should be noted that in this article, "several" and "at least one" refer to one or more, while "multiple" and "at least two" refer to two or more.
