[0002] As user demands increase, the performance of camera modules in electronic devices on the market is becoming more and more powerful. For example, some camera modules have image stabilization. Image stabilization is achieved by driving the camera module or a part of the camera module to move, thereby compensating for shooting errors caused by shaking. The camera module is usually electrically connected to the circuit board of the electronic device through a flexible circuit board, thereby realizing data transmission and circuit conduction between the camera module and the electronic device.

[0003] However, flexible circuit boards require the installation of numerous communication lines, resulting in a wider circuit board and a heavier weight. Consequently, during motion stabilization operations, the weight of the flexible circuit board exerts a significant pulling force on the camera module, creating considerable resistance to its movement and consequently reducing its stabilization accuracy, thus affecting its overall stabilization performance.

[0018] The electronic device and its control method and control device provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0019] Please refer to Figures 1 to 7 This application discloses an electronic device 100, which includes a device body 110 and a camera module 120.

[0020] The main body 110 is the main component of the electronic device 100, and includes, but is not limited to, components such as a housing, display module, and motherboard. The main body 110 is equipped with a control chip 111 and a first wireless transmission module 112. The control chip 111 is a system-on-a-chip (SoC), which integrates a central processing unit, graphics processor, communication unit, power management unit, and various interface circuits. It is a single-chip integrated circuit capable of independently performing data processing, signal transmission and reception, and system control. The first wireless transmission module 112 is used for wireless transmission of electrical signals. The control chip 111 and the first wireless transmission module 112 are electrically connected. Since both the first wireless transmission module 112 and the control chip 111 are housed within the housing of the main body 110, the first wireless transmission module 112 can be electrically connected to the control chip 111 via wires or a circuit board.

[0021] The camera module 120 is used to realize the shooting function of the electronic device 100. The camera module 120 is located in the inner cavity of the device body 110. This can be understood as the camera module 120 being located inside the housing of the device body 110. The housing has a light-transmitting area, through which external light enters the camera module 120. The incoming light is received by the image sensor 1221a of the camera module 120, thereby realizing the shooting function.

[0022] The camera module 120 includes a module housing 121 and a camera body 122. The module housing 121 provides a mounting base for other components of the camera module 120. The camera body 122 includes, but is not limited to, a lens, an image sensor 1221a, a circuit board, and other components. The camera body 122 is movably connected to the module housing 121. The module housing 121 is fixedly connected to the device body 110. In this case, the camera body 122 can move within the module housing 121, thus the camera module 120 has a micro-gimbal structure. Optionally, the camera body 122 can be slidably and / or rotatably connected to the module housing 121. During actual shooting, the camera body 122 moves relative to the module housing 121, thereby achieving image stabilization. In one embodiment, the camera body 122 can be rotatably connected to the module housing 121 via a pivot. Alternatively, in another embodiment, the camera body 122 can be slidably connected to the module body via a slide rail. Other movable connections are also possible, and this document does not limit these methods.

[0023] In this application, the camera module 120 can drive the camera body 122 to move relative to the module housing 121 via power components such as magnets and drive motors. The specific structure and driving method of the camera body 122 are known technologies and will not be described in detail here.

[0024] The camera body 122 includes a functional device 1221 and a second wireless transmission module 1222. The functional device 1221 refers to the device in the camera body 122 that enables the camera to perform its imaging function. The functional device 1221 includes, but is not limited to, components such as a circuit board, an image sensor 1221a, and a lens. The functional device 1221 and the second wireless transmission module 1222 are electrically connected. The second wireless transmission module 1222 is used to transmit electrical signals, and therefore is typically electrically connected to electronic devices. Thus, the second wireless transmission module 1222 can be electrically connected to components such as the circuit board and the image sensor 1221a of the camera body 122. The first wireless transmission module 112 and the second wireless transmission module 1222 can perform wireless transmission, establishing a wireless transmission path between them.

[0025] The main body of the device 110 and the camera module 120 transmit electrical signals through the first wireless transmission module 112 and the second wireless transmission module 1222.

[0026] In one embodiment, a wireless communication link can be established between the first wireless transmission module 112 and the second wireless transmission module 1222. In this case, the first wireless transmission module 112 and the second wireless transmission module 1222 are used to transmit data signals, such as image signals and control signals. The first wireless transmission module 112 and the control chip 111 can use signal transmission protocols such as DPHY or CPHY. The second wireless transmission module 1222 and the functional device 1221 can also use signal transmission protocols such as DPHY or CPHY.

[0027] Optionally, the first wireless transmission module 112 and the second wireless transmission module 1222 can establish a wireless communication link through communication protocols such as Bluetooth, near-field wireless communication, 2.4GHz wireless radio frequency communication, ultra-short-range wireless transmission, and dedicated short-range wireless communication. Specifically, the control chip 111 of the device body 110 compresses and modulates the control commands, configuration parameters, and other data signals to be transmitted into radio frequency signals, which are then transmitted outward by the first wireless transmission module 112 through its antenna. The second wireless transmission module 1222 receives the radio frequency signals through its antenna and transmits them to the functional device 1221. After decompression, demodulation, signal amplification, and shaping, the signals are restored to their original form. Conversely, the image data and status feedback data collected by the camera body 122 are compressed, modulated, and transmitted by the second wireless transmission module 1222. The first wireless transmission module 112 receives the data and transmits it to the control chip 111 for decompression, demodulation, signal amplification, and shaping, thereby completing the bidirectional, real-time data interaction between the device body 110 and the camera module 120.

[0028] In the above scheme, signal compression and decompression on the main body 110 can be achieved through the control chip 111, or a dedicated decompression and compression chip can be used. Signal compression and decompression on the camera module 120 can be achieved through the image sensor 1221a, or a dedicated decompression and compression chip can be used.

[0029] In one specific scheme, the first wireless transmission module 112 and the second wireless transmission module 1222 can communicate via Bluetooth to transmit data. In this scheme, based on the data transmission requirements of the image sensor 1221a, the transmission rate is greater than or equal to 1Gbps, power consumption is less than 100mW, and latency is less than or equal to 10ms. Compressed data transmission is used, so an excessively high rate is not required; only low power consumption and low latency are needed. Bluetooth communication features high transmission rate, low communication latency, and low power consumption, thus enabling rapid interaction of control commands, image stabilization parameters, and focus commands between the device body 110 and the camera body 122. This ensures the real-time performance of the image stabilization closed-loop control, avoids image stabilization response lag due to data delay, and improves image stabilization accuracy.

[0030] In another embodiment, power can be transferred between the first wireless transmission module 112 and the second wireless transmission module 1222. In this case, the device body 110 can power the camera module 120 via the first wireless transmission module 112 and the second wireless transmission module 1222. Specifically, the first wireless transmission module 112 is equipped with a transmitting coil, and the second wireless transmission module 1222 is equipped with a receiving coil. The control chip 111 of the device body 110 modulates electrical energy into an alternating electrical signal, which generates an alternating magnetic field through the transmitting coil. The receiving coil generates an induced current under the coupling induction of the alternating magnetic field, thereby providing operating power to the functional devices 1221 and the second wireless transmission module 1222 in the camera module 120, thus realizing contactless wireless power supply from the device body 110 to the camera module 120.

[0031] In another alternative embodiment, the first wireless transmission module 112 and the second wireless transmission module 1222 can perform both data transmission and power transmission.

[0032] In the embodiments disclosed in this application, some or all of the electrical signals between the camera module 120 and the device body 110 can be wirelessly transmitted through the first wireless transmission module 112 and the second wireless transmission module 1222. This reduces the amount of physical wiring between the camera body 122 and the device body 110, thereby reducing the wiring width of the flexible circuit board and consequently reducing the pulling force exerted by the flexible circuit board on the camera body 122 in motion, thus improving the motion accuracy of the camera body 122. Alternatively, the flexible circuit board can be completely eliminated, thereby completely eliminating the pulling force exerted by the flexible circuit board on the camera body 122 in motion, as well as the motion resistance caused by circuit deformation. Therefore, the electronic device 100 disclosed in this application enables the camera body 122 to experience purer force and more precise motion trajectory during image stabilization, effectively avoiding image stabilization deviations caused by interference from the flexible circuit board, and thus significantly improving the image stabilization accuracy of the camera module 120, thereby effectively improving the stability of the captured image.

[0033] In addition, reducing or eliminating physical wiring reduces or eliminates the need for wiring and bending space on flexible circuit boards, thereby reducing the installation space occupied by flexible circuit boards and thus reducing the overall size of the camera module 120, which is in line with the design trend of miniaturization and thinning of equipment.

[0034] In another optional embodiment, both the first wireless transmission module 112 and the second wireless transmission module 1222 can be wireless communication modules. These wireless communication modules include, but are not limited to, a radio frequency communication unit, an antenna unit, and a control interface unit. The radio frequency communication unit is responsible for signal modulation, demodulation, and wireless transmission and reception; the antenna unit is used to radiate and receive radio electromagnetic wave signals; and the control interface unit interacts with the control chip 111 or the functional device 1221 via electrical signals. The device body 110 and the camera module 120 achieve data transmission through the first wireless transmission module 112 and the second wireless transmission module 1222. The camera module 120 also includes a flexible circuit board, one end of which is electrically connected to the device body 110, and the other end of which is electrically connected to the camera body 122. The device body 110 supplies power to the camera body 122 through the flexible circuit board.

[0035] In this solution, the flexible circuit board is retained for wired power supply, which can provide a continuous, stable and high-power power supply to the functional components 1221 of the camera body 122, ensuring the working stability of the power supply of the camera body 122. At the same time, by stripping the data transmission function of the flexible circuit board, the flexible circuit board 123 is made lighter. Therefore, this solution takes into account both power supply reliability and image stabilization performance, thus balancing the power supply and motion performance of the camera module 120.

[0036] Furthermore, the flexible circuit board 123 may be provided with independent analog power lines and digital power lines. The analog power lines are used to power the analog circuitry of the camera body 122, and the digital power lines are used to power the digital circuitry of the camera body 122.

[0037] In this solution, the analog circuits of the camera module 122, such as the image sensor and signal amplification circuit, are highly sensitive to power supply noise, while the digital circuits, such as the control processing circuit and storage circuit, are prone to generating high-frequency pulse noise and ripple during operation. By using independent wiring, noise generated by the digital circuits is prevented from coupling to the analog circuits through the power lines, thus preventing problems such as image noise, color distortion, and signal distortion. Therefore, the purity of image signal acquisition is guaranteed from the power supply level, significantly improving the imaging quality of the camera module 120.

[0038] In another optional embodiment, the first wireless transmission module 112 may include a first wireless communication unit 1121 and a wireless charging transmitter unit 1122, both of which can be electrically connected to the control chip 111.

[0039] The second wireless transmission module 1222 may include a second wireless communication unit 1222a and a wireless charging receiver unit 1222b, both of which can be electrically connected to the functional device 1221.

[0040] The device body 110 and the camera module 120 can transmit data through the first wireless communication unit 1121 and the second wireless communication unit 1222a. Specifically, the control chip 111 of the device body 110 compresses and modulates the control commands, configuration parameters, and other data signals to be transmitted into radio frequency signals, which are then transmitted outward by the first wireless communication unit 1121 through its antenna. The second wireless communication unit 1222a receives the radio frequency signals through its antenna and transmits them to the functional device 1221. After decompression, demodulation, signal amplification, and shaping, the signals are restored to their original form. Conversely, the image data and status feedback data collected by the camera body 122 are compressed and modulated and transmitted by the second wireless communication unit 1222a. After being received by the first wireless communication unit 1121, the data is transmitted to the control chip 111 for decompression, demodulation, signal amplification, and shaping. This completes the bidirectional, real-time data interaction between the device body 110 and the camera module 120.

[0041] The power supply for the camera module 122 is provided by the wireless charging transmitter 1122 and the wireless charging receiver 1222b. Specifically, the wireless charging transmitter 1122 is equipped with a transmitting coil, and the wireless charging receiver 1222b is equipped with a receiving coil. The control chip 111 of the device module 110 modulates electrical energy into an alternating electrical energy signal, which generates an alternating magnetic field through the transmitting coil. The receiving coil generates an induced current under the coupling induction of the alternating magnetic field, thereby providing working power to the functional devices 1221 and the second wireless transmission module 1222 in the camera module 120, thus realizing non-contact wireless power supply from the device module 110 to the camera module 120.

[0042] In this solution, power supply and data transmission between the camera module 120 and the main body 110 are both wireless. Therefore, the flexible circuit board between the camera module 120 and the main body 110 can be completely eliminated, thereby further improving the image stabilization accuracy of the camera module 120 and thus further improving the stability of the captured image.

[0043] In addition, the flexible circuit board has been eliminated, and there is no need to reserve space inside the main body 110 for the flexible circuit board. This is conducive to further reducing the size of the electronic device 100, which in turn is conducive to the development of the electronic device 100 in a thinner and lighter form.

[0044] In another embodiment, the camera module 120 may further include a power signal processing element 124, which is electrically connected to the wireless charging receiver unit 1222b. The power signal processing element 124 includes, but is not limited to, rectifiers, filters, voltage regulators, protection devices, and power management chips. The power signal processing element 124 receives the raw power signal output from the wireless charging receiver unit 1222, performs rectification, filtering, and voltage regulation; subsequently, according to the power supply requirements of each circuit in the camera body 122, it outputs a stable and clean adaptive voltage, and also provides overvoltage and overcurrent protection, ultimately providing stable power to components such as the analog power supply, digital power supply, and the second wireless communication unit 1222a.

[0045] In this solution, the power signal processing element 124 can perform voltage stabilization, filtering, rectification, and noise reduction on the voltage and current output by the wireless charging receiver unit 1222b, thereby eliminating voltage fluctuations, ripples, and noise interference generated during wireless power transmission. This makes the power output to the camera body 122 cleaner and more stable, avoiding problems such as image jitter, abnormal focusing, and restart of functional device 1221 caused by voltage instability. Therefore, it improves the overall stability and safety of the camera module 120.

[0046] In another optional embodiment, the camera module 120 may further include a power storage module, which can be electrically connected to both the wireless charging receiver unit 1222 and the functional device 1221. In this solution, wireless power transmission is prone to voltage instability due to the camera body 122's anti-shake movement and coupling position shift. The power storage module can dynamically store and release energy, replenishing power in time when the wireless power supply drops or fluctuates instantaneously; and storing surplus energy when the wireless power supply is sufficient, thereby ensuring that the camera body 122 receives uninterrupted and stable power supply, avoiding screen flickering, focusing abnormalities, or functional device 1221 reset due to voltage fluctuations. Therefore, it helps to improve the overall stability and safety of the camera module 120. In addition, by using the power storage module for energy buffering, the long-term high-load operation of the wireless charging receiver unit 1222b is reduced, heat generation and losses are reduced, device aging is delayed, and the reliability and service life of the entire power supply link are improved.

[0047] In one specific scheme, the electrical energy output by the wireless charging receiver unit 1222b is regulated and filtered by the power signal processing element 124. Part of it can be directly supplied to the functional device 1221, and the other part can be stored in the energy storage module. When the instantaneous power consumption of the functional device 1221 increases or the wireless power output is insufficient, the energy storage module releases the stored electrical energy to replenish the power, realizing energy buffering and dynamic energy replenishment, and ensuring continuous and stable power supply.

[0048] Optionally, the energy storage module can be a micro battery, button battery, supercapacitor, lithium-ion capacitor, etc.; supercapacitors are preferred because they have the characteristics of fast charging and discharging, small size, and long cycle life, which are suitable for the 120 instantaneous high power requirements of the camera module.

[0049] In one embodiment, the wireless charging transmitter 1122 can be fixed inside the device body 110, specifically on the main board of the device body 110.

[0050] In another optional embodiment, the wireless charging transmitter 1122 can be fixed to the module housing 121. In this case, fixing the wireless charging transmitter 1122 to the module housing 121 makes the relative distance between the wireless charging transmitter 1122 and the wireless charging receiver 1222b closer, the position more fixed, and the coupling angle more stable. This significantly improves the magnetic field coupling efficiency between the coils, reduces energy transmission loss, and results in higher wireless power and better transmission efficiency.

[0051] In addition, the wireless charging transmitter 1122 is directly fixed on the module housing 121, eliminating the need to reserve space for long-distance installation, thus making the layout of the electronic device 100 more compact and helping to further reduce the size of the electronic device 100.

[0052] In another embodiment, the main body 110 may also include a first circuit board 113, which can be the motherboard of the main body 110. Both the control chip 111 and the first wireless transmission module 112 can be located on the first circuit board 113. In this embodiment, the control chip 111 and the first wireless transmission module 112 are located on the same circuit board, thereby further optimizing the internal layout of the electronic device 100 and thus contributing to the thinner and lighter design of the electronic device 100.

[0053] In one embodiment, the aforementioned wireless charging transmitter 1122 can also be disposed on the first circuit board 113.

[0054] In one embodiment, the functional device 1221 may include an image sensor 1221a and a second circuit board 1221b, both of which may be disposed on the second circuit board 1221b. In this solution, the image sensor 1221a and the second wireless transmission module 1222 are both disposed on the same circuit board, thereby further optimizing the internal layout of the camera module 120, which in turn helps to reduce the size of the camera module 120, and consequently, further reduces the size of the electronic device 100.

[0055] Based on the electronic device 100 disclosed in the embodiments of this application, this application discloses a control method for the electronic device 100. The disclosed control method is executed by the electronic device 100 described above, such as... Figure 8 As shown, the disclosed control method includes: S101, Obtain the first electrical signal.

[0056] The first electrical signal here can be an electrical energy transmission signal, or a control or feedback signal.

[0057] S102 transmits the first electrical signal to the first wireless transmission module 112.

[0058] The control chip 111 can transmit the first signal to the first wireless transmission module 112. When the first signal is an electrical signal, the control chip 111 modulates the electrical energy into an alternating electrical signal and then transmits it to the first wireless transmission module 112. When the first signal is a data signal, the control chip 111 compresses and modulates the control commands, configuration parameters, and other data signals to be transmitted into radio frequency signals, and transmits them to the first wireless transmission module 112 through a corresponding signal transmission protocol. For example, the transmission protocol between the control chip 111 and the first wireless transmission module 112 can be DPHY / CPHY.

[0059] S103, The first electrical signal is sent to the second wireless transmission module 1222 through the first wireless transmission module 112.

[0060] When the first signal is an electrical signal, the first wireless transmission module 112 and the second wireless transmission module 1222 are coupled together. When the first signal is a data signal, the first wireless transmission module 112 and the second wireless transmission module 1222 can establish a wireless communication link through communication protocols such as Bluetooth, near-field wireless communication, 2.4GHz wireless radio frequency communication, ultra-short-range wireless transmission, and dedicated short-range wireless communication.

[0061] S104, Receive the first electrical signal through the second wireless transmission module 1222.

[0062] At this time, the second wireless transmission module 1222 receives the first electrical signal transmitted by the first wireless transmission module 112.

[0063] S105, The first electrical signal is transmitted to the functional device 1221.

[0064] When the first signal is an electrical signal, the second wireless transmission module 1222 generates an induced current under the coupling induction of the alternating magnetic field, thereby providing operating power to the functional device 1221 and the second wireless transmission module 1222 in the camera module 120. When the first signal is a data signal, the second wireless transmission module 1222 receives the radio frequency signal through its antenna and transmits the radio frequency signal to the functional device 1221. After decompression, demodulation, signal amplification, and shaping, the signal is restored to the original data signal.

[0065] In the embodiments disclosed in this application, some or all of the electrical signals between the camera module 120 and the device body 110 can be wirelessly transmitted through the first wireless transmission module 112 and the second wireless transmission module 1222. This reduces the amount of physical wiring between the camera body 122 and the device body 110, thereby reducing the wiring width of the flexible circuit board and consequently reducing the pulling force exerted by the flexible circuit board on the camera body 122 in motion, thus improving the motion accuracy of the camera body 122. Alternatively, the flexible circuit board can be completely eliminated, thereby completely eliminating the pulling force exerted by the flexible circuit board on the camera body 122 in motion, as well as the motion resistance caused by circuit deformation. Therefore, the electronic device 100 disclosed in this application enables the camera body 122 to experience purer force and more precise motion trajectory during image stabilization, effectively avoiding image stabilization deviations caused by interference from the flexible circuit board, and thus significantly improving the image stabilization accuracy of the camera module 120, thereby effectively improving the stability of the captured image.
