Description

Technical Field

[0001] This invention relates to the field of image stabilization micro-gimbal technology, and particularly to a micro-gimbal camera module and electronic device. Background Technology

[0002] A micro-gimbal camera module, also known as a camera module equipped with a micro-gimbal, has excellent tilt-shift image stabilization capabilities. This means that optical image stabilization is achieved by deflecting the angle of the shooting optical axis. To achieve optical axis deflection, the micro-gimbal camera module mainly includes: a micro-gimbal bracket, a camera module, and a drive mechanism connecting the two. The camera module is rotatably connected to the micro-gimbal bracket, and the drive mechanism drives the camera module to deflect relative to the micro-gimbal bracket, thereby deflecting the angle of the camera module's optical axis and achieving optical image stabilization.

[0003] The aforementioned driving mechanism mainly consists of a magnet, a coil, and a driving circuit. The magnet and the coil are respectively mounted on the camera module and the micro-gimbal bracket, and the coil is connected to the driving circuit. The magnitude and direction of the current applied to the coil are controlled by the anti-shake driving chip and the magnetic field sensor configured on the driving circuit, so as to form an adjustable magnetic force between the coil and the magnet, thereby adjusting the deflection direction and amplitude of the camera module relative to the micro-gimbal bracket.

[0004] The camera module has a complete shooting function structure that is independent of the aforementioned drive mechanism. Each of them is equipped with independent drive and control circuits, and both are integrated flexible printed circuit boards. That is, the camera module is equipped with a module circuit board, and the drive mechanism is equipped with a drive circuit board. Both are independently connected to and communicate with the upstream equipment, and each occupies an independent installation space in the camera module. This undoubtedly leads to a complex external connection structure for the entire micro-gimbal camera module, a large installation space requirement, and is not conducive to its assembly and use in terminal products. Summary of the Invention

[0005] This invention provides a micro-gimbal camera module and electronic device, solving the technical problems of complex structure and large space occupation of existing micro-gimbals.

[0006] To address the aforementioned technical problems, one aspect of the present invention provides a micro-gimbal camera module, comprising: a camera module, a gimbal support, a coil assembly, a magnet assembly, and a gimbal drive control element;

[0015] The coil and the magnetic field sensor are fixed on the camera module, and the coil and the magnetic field sensor are respectively connected to the module circuit board.

[0016] In some embodiments, the gimbal support includes: a housing and a deflection support;

[0017] The deflection support is deflected within the housing about the first direction, and the camera module is deflected within the deflection support about the second direction.

[0018] The magnet assembly is disposed on the housing;

[0019] Wherein, the first direction is perpendicular to the second direction, and both the first direction and the second direction are perpendicular to the optical axis of the camera module.

[0020] In some embodiments, the coil assembly includes a first-direction coil assembly and a second-direction coil assembly, and the magnet assembly includes a first-direction magnet assembly and a second-direction magnet assembly;

[0021] The first direction coil assembly and the first direction magnet assembly are disposed opposite to each other, and when the first direction coil assembly is energized, the force between the first direction coil assembly and the first direction magnet assembly drives the camera module and the deflection support as a whole to deflect about the first direction as an axis.

[0022] The second direction coil assembly and the second direction magnet assembly are arranged opposite to each other, and when the second direction coil assembly is energized, the force between the second direction coil assembly and the second direction magnet assembly drives the camera module to deflect relative to the gimbal support about the second direction as the axis.

[0023] In some embodiments, the gimbal drive control element is integrated onto the module circuit board.

[0026] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0027] The micro-gimbal camera module and electronic device provided in this application embodiment adopt a combined structure of camera module and micro-gimbal. The micro-gimbal is used to achieve deflection-axis stabilization to improve shooting quality. Specifically, the magnetic force between the energized coil assembly and the magnet assembly serves as the driving force for the gimbal's axis-shifting stabilization, causing the camera module to deflect within the gimbal support, thus achieving stabilization compensation. The coil assembly and gimbal drive control element are connected to the camera module's module circuit board as a whole, eliminating the need for a separate control circuit board structure for the gimbal. This simplifies the overall structure of the micro-gimbal camera module, reduces complexity, and decreases space requirements, thereby reducing the installation space requirements for terminal devices and facilitating installation on terminal devices, thus expanding the range of products that can be mounted. Furthermore, by fixing the magnet assembly to the gimbal support and placing the coil assembly on the camera module, the gimbal support becomes a passive structure, simplifying structural forming and assembly operations and improving production efficiency to some extent.

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0046] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0047] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0048] To better understand the above technical solutions, the following will describe the above technical solutions in detail with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solutions of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0049] Micro-gimbal camera modules are typically mounted on product terminals and communicate with upstream devices such as the product terminal's control system to achieve various shooting functions. They can also utilize the deflection and tilt-shift functions of the micro-gimbal to drive the entire camera module to deflect in two perpendicular directions to achieve tilt-shift image stabilization and improve shooting quality. Typically, the micro-gimbal has a driver circuit board that connects to upstream devices to obtain drive control commands to drive the camera module to deflect and implement tilt-shift image stabilization. The camera module has a module circuit board that communicates with upstream devices to perform shooting operations.

[0050] Because the driver circuit board and the module circuit board are functionally and structurally independent and are each housed within the space of the micro-gimbal camera module, the external connection and communication structure of the micro-gimbal camera module is complex and occupies a large space, which is not conducive to its assembly and use on the product terminal.

[0051] Therefore, this application provides a micro-gimbal camera module and electronic device, which to some extent solves the technical problems of complex structure and large space occupation of micro-gimbals in the prior art; thereby achieving the technical effect of simplifying the electrical connection and communication structure of micro-gimbals, reducing space occupation requirements, and expanding the range of products that can be adapted and installed.

[0052] This application is described below with reference to the accompanying drawings and specific embodiments.

[0053] The micro-gimbal camera module and electronic device provided in this application are designed to simplify the structure of the micro-gimbal camera module through structural optimization and layout, reduce the overall structural size and space occupation, thereby expanding its adaptability range to a certain extent, enabling it to be installed and used on terminal devices with smaller specifications and less installation space, and reducing the cost of use and assembly complexity.

[0054] See Figure 1 , Figure 2 and Figure 5 The micro-gimbal camera module involved in this embodiment includes: a camera module 100 and a gimbal support 200. The camera module 100 is rotatably connected to the gimbal support 200 so that the optical axis direction of the camera module 100 can be adjusted by deflecting the camera module 100 as a whole, thereby achieving the effect of image stabilization compensation.

[0055] In order to drive the camera module 100 to deflect, this embodiment of the application adopts a driving principle architecture based on the interaction of an energized coil and a magnet. By arranging the positions of the coil and the magnet and controlling the direction and magnitude of the current in the coil, the magnitude and direction of the thrust are controlled, thereby driving the camera module 100 to rotate around a set axis.

[0056] See Figure 2 , Figure 3 , Figure 7 , Figure 8and Figure 9 The camera module 100 includes a camera module body 110. In order to drive the camera module 100 to deflect, a coil assembly 300 can be provided on the camera module body 110, and a magnet assembly 400 can be provided on the gimbal support. The coil assembly 300 and the magnet assembly 400 are arranged close to each other, so that the coil assembly 300 is located within the magnetic field range of the magnet assembly 400. After a DC current signal is applied to the coil assembly 300, a magnetic force will be generated between the coil assembly 300 and the magnet assembly 400. The magnetic force can drive the camera module body 110 to deflect relative to the gimbal support 200.

[0057] The direction and magnitude of the magnetic force are related to the magnitude and direction of the current applied to the coil assembly 300. Therefore, the deflection amplitude and direction of the camera assembly body 110 relative to the gimbal support 200 can be adjusted by controlling the magnitude and direction of the current applied to the coil assembly 300.

[0058] Correspondingly, after the current signal on the coil assembly 300 disappears, the magnetic force between the coil assembly 300 and the magnet assembly 400 also disappears.

[0059] Typically, the current applied to the coil assembly 300 does not disappear suddenly, but changes linearly, such as gradually increasing or decreasing, to avoid large vibrations during the deflection process caused by drastic changes.

[0060] See Figure 2 , Figure 3 and Figure 4 In order to control and adjust the current signal applied to the coil assembly 300, the gimbal drive control element 130 can be connected to the coil assembly 300 to output a DC current signal with adjustable magnitude and direction to the coil assembly 300.

[0061] The gimbal drive control element 130 can be connected to the module circuit board 111 of the camera module body 110, and the coil assembly 300 is also connected to the module circuit board 111, thereby realizing the connection between the gimbal drive control element 130 and the coil assembly 300 through the transmission circuit of the module circuit board 111. On the other hand, the gimbal drive control element 130 also uses the module circuit board 111 to realize the communication connection with the upstream device, obtain the gimbal action control command, and output the corresponding current signal.

[0062] It is worth noting that the gimbal drive control element 130 can be directly connected to the module circuit board 111, and the coil assembly 300 is fixed on the camera module body 110 and connected to the module circuit board 111 nearby. That is, there is no need to set up a separate gimbal drive circuit board and connector. Instead, the gimbal drive control element 130 and the coil assembly 300 are connected to the module circuit board 111, and the module circuit board 111 is used to communicate directly with the upstream equipment. Thus, while taking into account the deflection control of the gimbal, the micro-gimbal camera module does not need to set up a separate gimbal drive circuit board, nor does it need to reserve installation space for the gimbal drive circuit board. This simplifies the structure of the micro-gimbal camera module and reduces the overall size. During assembly, the assembly process is also simplified to a certain extent.

[0063] See Figure 6 , Figure 7 and Figure 9 The magnet assembly 400 is disposed on the gimbal support 200, and the magnet assembly 400 is opposite to the coil assembly 300. Accordingly, both the magnet assembly 400 and the gimbal support 200 are passive structural components, so they do not require additional circuit components or electrical connections with the camera module body 110. This reduces the overall structural size and allows the gimbal to be installed on smaller carrier terminals, further expanding its installation adaptability and making it easier to install and use.

[0064] In some embodiments, the camera module body 110 has an independent shooting and imaging function, including: a lens and an image sensor chip, which are used to gather and transmit light signals respectively, and are identified and converted into electrical signals by the image sensor chip and transmitted back to the upstream device in the back end to realize imaging conversion.

[0065] The camera module body 110 also includes a main support for housing the image sensor chip, which is connected to the module circuit board 111 for communication with upstream devices. A chip stabilization structure can also be installed within the main support and connected to the module circuit board 111 to drive the image sensor chip to translate or rotate around its optical axis within the main support, achieving chip stabilization. The lens can also be fixed to the main support via a lens bracket and can be configured with a focusing drive mechanism, such as a voice coil motor, connected to the module circuit board 111 for focusing operations. A filter can also be placed between the lens and the image sensor chip to filter interfering light and ensure image quality.

[0066] See Figure 5 and Figure 6In some embodiments, the gimbal support 200 includes a housing 210 and a deflection support 220; wherein, the housing 210 serves as the basis for the micro-gimbal deflection operation, the deflection support 220 deflects within the housing 210 about a set first direction as an axis, and the camera module body 110 deflects within the deflection support 220 about a set second direction as an axis, thereby realizing two independent deflection operations.

[0067] Generally, the first direction and the second direction are two mutually perpendicular directions, and both are perpendicular to the optical axis direction of the camera module body 110.

[0068] See Figure 6 In some embodiments, in order to achieve the deflection of the deflection support 220, a deflection bracket 240 can be fixed on the deflection support 220, and two first deflection arms 241 are respectively provided at both ends of the deflection bracket 240 along the first direction. A first deflection groove 212 adapted to the two first deflection arms 241 is opened on the outer shell 210. The first deflection arms 241 deflect in a plane perpendicular to the first direction by setting a pin along the first direction, so that the deflection support 220 can deflect relative to the outer shell 210 around the first direction.

[0069] Generally, a fixing part 243 can be provided on the deflection bracket 240, and the deflection bracket 240 can be fixed to the deflection support 220 by fasteners at the fixing part 243; specifically, a fixing hole is provided at the fixing part 243, and the deflection bracket 240 is locked and fixed to the deflection support 220 by screws, bolts, etc.

[0070] To facilitate positioning, a fixing slot 222 can be provided on the deflection support 220 to embed the first deflection arm 241, thereby achieving convenient positioning and installation.

[0071] In some embodiments, in order to achieve the deflection of the camera module body 110 within the deflection support 220, two second deflection arms 242 can be provided at both ends of the deflection bracket 240 along the second direction, and a second deflection groove 223 that can accommodate the deflection of the two second deflection arms 242 can be opened on the deflection support 220. Then, two pins are provided on the camera module body 110 along the second direction, and the pins are rotatably embedded in the corresponding pin holes opened in the second deflection arms 242, thereby achieving the deflection of the camera module body 110 around the second direction in the deflection support 220.

[0072] Generally, in order to strengthen the outer shell 210 and protect the internal structure, a snap-on top cover 230 can be provided on the outer shell 210; the top cover 230 can be configured as an annular frame to facilitate the passage of components such as lenses.

[0073] See Figure 2 , Figure 3 , Figure 7 and Figure 8 In some embodiments, in order to achieve deflection anti-shake in two mutually perpendicular directions, at least two vertical deflection drive structures should be provided; for this purpose, the coil assembly 300 may include a first direction coil assembly 310 and a second direction coil assembly 320, and correspondingly, the magnet assembly 400 is also respectively configured as a first magnet assembly 410 and a second magnet assembly 420.

[0074] The first direction coil assembly 310 and the first magnet assembly 410 are opposite each other. When the first direction coil assembly 310 is energized, the magnetic force between the first direction coil assembly 310 and the first direction magnet assembly 410 drives the camera module body 110 and the deflection support 220 connected thereto to deflect relative to the outer shell 210 around the first direction axis.

[0075] The second direction coil assembly 320 is opposite to the second magnet assembly 420. When the second direction coil assembly 320 is energized, the magnetic force between the second direction coil assembly 320 and the second direction magnet assembly 420 drives the camera module body 110 to deflect relative to the outer shell 210 and the deflection support 220 around the second direction axis.

[0076] Therefore, under the control of the gimbal drive control element 130, the magnitude and direction of the current of the first coil assembly 310 and the second coil assembly 320 are controlled, and the deflection stabilization operation of the camera module body 110 is implemented independently.

[0077] It is worth noting that the first coil assembly 310 and the second coil assembly 320 have the same structure, and the first magnet assembly 410 and the second magnet assembly 420 have the same structure. For ease of explanation, the following description will use the first coil assembly 310 and the first magnet assembly 410 as examples to illustrate the specific structure of the coil assembly 300 and the magnet assembly 400.

[0078] See Figure 3In some embodiments, to improve the deflection control accuracy of the camera module body 110, the deflection process of the camera module body 110 can be controlled by feedback. That is, the first direction coil assembly 310 can be set as an independent first direction coil 312 and first direction magnetic field sensor 313, which are connected through the module circuit board 111 respectively. The magnetic field sensor 313 can be set on the camera module body 110 to detect the magnetic field strength of the first direction magnet assembly 410 in real time, as an indicator to determine whether the camera module body 110 has deflected to the correct position in the first direction. This feedback controls the output current of the gimbal drive control element 130 to avoid the camera module body 110 not deflecting to the correct position due to various disturbance factors.

[0079] In some embodiments, the first directional magnetic field sensor 313 can transmit the detection signal to an upstream device through the module circuit board 111, and the upstream device can give a control command to adjust the output current of the gimbal drive control element 130.

[0080] See Figure 4 In some embodiments, the gimbal drive control element 130 may be configured as a current control chip, integrated and connected on the module circuit board 111, as a component of the camera module body 110.

[0081] Correspondingly, the gimbal drive control element 130 communicates with upstream devices through the transmission circuit on the module circuit board 111 and the module circuit board connector 111a.

[0082] The module circuit board 111 is equipped with various functional circuits and components to meet the shooting function requirements of the camera module 100. The gimbal drive control element 130 and its related circuits and electronic components can be flexibly integrated into the module circuit board 111 as a component, thereby simplifying the overall circuit structure of the micro gimbal camera module and making product molding and assembly more convenient and efficient.

[0083] Generally, disturbance factors may include line faults that cause the current loaded on the coil assembly 300 to be diverted, resulting in insufficient actual deflection driving force; or friction of the deflection mechanism; or structural faults, etc.

[0084] See Figure 3 In some embodiments, the first directional magnetic field sensor 313 can be placed at the center of the first directional coil 312 to more accurately reflect the magnetic field situation of the first directional coil 312.

[0085] Generally, for ease of fixing and assembly, the first directional coil 312 and the first directional magnetic field sensor 313 can be glued to the camera module body 110; of course, fasteners, slots and other fixing structures can also be used, and the surface design on the camera module body 110 can be used to meet the assembly requirements, which will not be elaborated here.

[0086] See Figure 3 In some embodiments, for ease of assembly, the first directional coil 312 and the first directional magnetic field sensor 313 can be respectively connected to a printed circuit board, namely the first directional PCB circuit board 311. That is, the first directional coil assembly 310 is configured as an integrated assembly of the first directional PCB circuit board 311, the first directional magnetic field sensor 313 and the first directional PCB circuit board 311, and is assembled onto the camera module body 110. The first directional PCB circuit board 311 can be extended and soldered to the module circuit board 111 through pins, pads or printed circuits, simplifying electrical connection operations, thereby making the overall structure simple, orderly, and easy to install and manage.

[0087] Typically, the first-direction PCB circuit board 311 can be used as a carrier and fixed to the camera module body 110 by snap-fit ​​or adhesive method, which is simple to operate and easy to form a stable fixed state.

[0088] In some embodiments, the PCB circuit boards of the first coil assembly 310 and the second coil assembly 320 can both be configured as flexible printed circuit boards and integrated into one unit, so that the flexible printed circuit board can be bent to adapt to different positions on the camera module body 110, and then the whole assembly is electrically connected to the module circuit board 111 at one or more connection points.

[0089] In some embodiments, the module circuit board 111 may also be fixed inside the camera module body 110 in the form of a PCB integrated circuit board, simplifying electrical connection operations.

[0090] See Figure 8 In some embodiments, the outer casing 210 can be configured as a square structure with closed sides, leaving the top and bottom open for installation and maintenance. Correspondingly, the main body of the camera module 110 can also be roughly square in shape, facilitating assembly and manufacturing. This also facilitates the reference arrangement of the internal structure, improving assembly efficiency.

[0091] See Figure 7 , Figure 8 and Figure 9Since the magnet assembly 400 has a normal magnetic field, in order to reduce its influence on other components outside the gimbal, the first magnet assembly 410 can be configured as a combination structure of a first-direction magnetic shielding base 411 and a first-direction magnet 412.

[0092] Specifically, the first magnetic shielding base 411 is disposed on the gimbal support 210, and the first directional magnet 412 is fixed on the first directional magnetic shielding base 411 to shield the magnetic field toward the outside of the gimbal support 210.

[0093] Of course, the first direction magnetic shielding base 411 can also serve as a component to shield external magnetic fields. Specifically, a shielding space can be formed in the area of ​​the first direction magnet 412 and the first direction coil 312 to prevent external magnetic fields from affecting the anti-shake operation and improve the reliability of gimbal anti-shake.

[0094] The first direction magnet 412 can usually be glued to the first direction magnetic shielding base 411, which is easy to install.

[0095] In some embodiments, the first directional magnetic shielding base 411 can be configured as a sheet-like structure and embedded in the outer shell 210, improving the convenience of molding, preparation, and assembly. The first directional magnetic shielding base 411 can also be configured as a metal sheet.

[0096] See Figure 9 In some embodiments, the first directional magnetic shielding base 411 is embedded in the outer shell 210 of the gimbal support 200 by an insert molding process, which can reduce the thickness of the outer shell 210 to a certain extent.

[0097] Of course, the magnetic shielding base 411 can also be directly glued to the outer shell 210, or a groove 211 can be opened on the outer shell 210 and the outer shell 210 can be embedded in the groove 211 and reinforced by adhesive; other methods are also not excluded.

[0098] See Figure 6 In some embodiments, in order to balance the smoothness of the deflection of the camera module body 110 relative to the deflection support 220 and the simplicity of the structure, the deflection support 220 is provided with a clearance groove 221 for avoiding the coil assembly 300; that is, the clearance groove 221 provides deflection space for the coil assembly 300, which is particularly suitable for application in the mode architecture in which the coil assembly 300 is fixed on the surface of the camera module body 110.

[0099] Accordingly, the magnet assembly 400 is fixed on the housing 210 and can be specifically arranged in the area opposite to the clearance groove 221.

[0100] See Figure 10 The micro-gimbal B provided in this application embodiment optimizes the structure and layout. Compared with the existing micro-gimbal A, it removes the internal gimbal drive circuit board A3 and cloud drive circuit board connector A4, and integrates them with the existing module circuit board A1, sharing the existing module circuit board connector A2, thereby obtaining the module circuit board 111 and the module circuit board connector 111a provided in this application embodiment; and optimizes the layout of the coil assembly 300 and the magnet assembly 400, so that the circuit connection is concentrated on the camera module body 110, and the gimbal support 220 forms a purely mechanical structure, thereby significantly reducing the overall width of the micro-gimbal camera module and the width of the cable tray placement area, greatly reducing the complexity of the space specifications and circuit flow connection structure.

[0101] In some embodiments, an electronic device equipped with the aforementioned micro-gimbal camera module is also provided, which can optimize the spatial layout and utilization of the electronic device.

[0102] Generally, the electronic device can be a mobile phone, a tablet computer, or other electronic devices.

[0103] Alternatively, the aforementioned gimbal drive control element 130 can be directly integrated into the circuit structure of the product, such as a mobile phone or tablet, and the coil assembly 300 can be connected to the module circuit board 111a and the module circuit board 111.

[0104] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0105] The micro-gimbal camera module and electronic device provided in this application embodiment adopt a combined structure of camera module and micro-gimbal. The micro-gimbal is used to achieve deflection-axis stabilization to improve shooting quality. Specifically, the magnetic force between the energized coil assembly and the magnet assembly serves as the driving force for the gimbal's axis-shifting stabilization, causing the camera module to deflect within the gimbal support, thus achieving stabilization compensation. The coil assembly and gimbal drive control element are connected to the camera module's module circuit board as a whole, eliminating the need for a separate control circuit board structure for the gimbal. This simplifies the overall structure of the micro-gimbal camera module, reduces complexity, and decreases space requirements, thereby reducing the installation space requirements for terminal devices and facilitating installation on terminal devices, thus expanding the range of products that can be mounted. Furthermore, by fixing the magnet assembly to the gimbal support and placing the coil assembly on the camera module, the gimbal support becomes a passive structure, simplifying structural forming and assembly operations and improving production efficiency to some extent.
