[0024] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] refer to Figures 1 to 3 A gimbal shooting device 200 according to an embodiment of the present invention is used to capture images of a subject and can adjust the shooting azimuth angle during the shooting process to optimize the image quality caused by shaking deviation during the shooting process. This gimbal shooting device 200 can be used directly or applied to a shooting terminal 10, meaning the shooting terminal 10 has an image stabilization function. In one embodiment, the shooting terminal 10 includes a main body 100 and the gimbal shooting device 200 disposed within the main body 100. In one embodiment, the shooting terminal 10 is a camera (e.g., a digital still camera). It is understood that in other embodiments, the shooting terminal 10 can also be a smart terminal with a camera function, such as a smartphone, laptop, tablet, portable telephone, video phone, e-book reader, portable multimedia player (PMP), mobile medical device, or wearable device.

[0028] In existing technologies, most shooting terminals are clamped onto a gimbal and driven to rotate by a motor to achieve physical image stabilization, thereby ensuring the stability of the images captured by the shooting terminal. However, the gimbal and shooting terminal are independently set up, occupying a large volume and being complex to install and use. The gimbal shooting device 200 of the present invention is integrated into the shooting terminal 10, which can reduce the overall size of the gimbal shooting device 200. Furthermore, the user can directly use the shooting terminal 10 to adjust the shooting azimuth angle changes during the shooting process through the gimbal shooting device 200 inside the shooting terminal 10, thereby optimizing the image quality problems caused by shake deviations during the shooting process.

[0029] The main body 100 is the mounting carrier of the gimbal shooting device 200. The main body 100 can be made of a metallic material, such as aluminum, aluminum alloy, or stainless steel. Alternatively, it can be made of a non-metallic material such as plastic. The main body 100 includes a first mounting surface 110, a second mounting surface 120, and a side surface 130 connecting the first mounting surface 110 and the second mounting surface 120, all arranged opposite to each other. The opposite arrangement can be understood as follows: for example, along the thickness direction of the side surface 130 (…). Figure 1 In the Y-axis direction, assuming a reference plane parallel to the XZ plane is defined at a point in the middle of the side 130, all points on the first mounting surface 110 are located on one side of the reference plane, and all points on the second mounting surface 120 are located on the other opposite side of the reference plane.

[0030] The first mounting surface 110 of the body 100 may have a light-transmitting hole 111 for light to be received by the camera module 220 of the gimbal shooting device 200. In one embodiment, the first mounting surface 110 of the body 100 is provided with an optical lens 112 covering the light-transmitting hole 111. The optical lens 112 protrudes toward the side away from the camera module 220, that is, the optical lens 112 protrudes from the body 100, thereby sufficiently expanding the light-receiving range of the camera module 220 in the gimbal shooting device 200. In one embodiment, the shooting terminal 10 also includes a display screen 300, which is mounted on the second mounting surface 120 of the body 100. The display screen 300 may be a liquid crystal display (LCD) or an organic light-emitting diode (OLED) display screen. In one embodiment, the display screen 300 is a touch screen, allowing users to manipulate the information displayed on the screen via touch. For example, a touch operation can trigger a shooting command from the camera module 220 in the gimbal shooting device 200. In other embodiments, the display screen 300 may be a non-touch screen, used only for information display. In other embodiments, the display screen 300 may be omitted. The side surface 130 of the main body 100 may have slots, holes, or other structures for mounting peripheral components that implement specific elements to form a detachable connection with the shooting terminal 10, or for serving as a channel for input / output of signals such as sound, or as a channel for heat dissipation of internal components of the shooting terminal 10. In one embodiment, the side surface 130 of the main body 100 has a battery mounting slot 131 for mounting the battery 400.

[0031] In one embodiment, the body 100 includes a front shell 101, a rear shell 102, and a middle frame 103. The front shell 101 and the rear shell 102 are connected to form a receiving cavity. The middle frame 103 is disposed within the receiving cavity. The gimbal shooting device 200 is connected to the middle frame 103. The front shell 101 and the rear shell 102 are used to seal and mount the gimbal shooting device 200 mounted on the middle frame 103. In this case, the end face of the front shell 101 away from the middle frame 103 is the first mounting surface 110, the outer wall surface of the front shell 101 is the side surface 130 of the body 100, and the end face of the rear shell 102 away from the middle frame 103 is the second mounting surface 120.

[0032] Please refer to Figure 4 and Figure 5In one embodiment, the gimbal shooting device 200 includes a drive module 210 and a camera module 220. The drive module 210 is used to control the shooting position of the camera module 220 so that the camera module 220 can achieve optical image stabilization during shooting. That is, when the camera module 220 shakes during shooting, in order to eliminate the displacement deviation caused by the shaking during shooting, the drive module 210 can act on the camera module 220 to generate a force to counteract the displacement deviation, so as to realize the stabilization function of the gimbal shooting device 200.

[0033] In one embodiment, the drive module 210 includes a first drive member 230, a second drive member 240, and a third drive member 250. The first drive member 230, the second drive member 240, and the third drive member 250 work together to achieve stabilization of the shooting terminal 10 and multi-angle shooting (three-axis stabilization).

[0034] The first driving member 230 includes a first fixed part 231 and a first rotating part 232 connected to each other. The first rotating part 232 is rotatable relative to the first fixed part 231. The rotation axis of the first rotating part 232 extends along a first direction, which can be understood as being perpendicular to the first fixed part 231. Figure 4 The direction is parallel to the Y-axis. The camera module 220 is connected to the first rotating part 232 and can rotate together with the first rotating part 232.

[0035] The second driving member 240 includes a second fixed part 241 and a second rotating part 242 connected to each other. The second rotating part 242 is rotatable relative to the second fixed part 241. The rotation axis of the second rotating part 242 extends along a second direction, which can be understood as being perpendicular to the second fixed part 241. Figure 4 The direction is parallel to the X-axis. The second rotating part 242 is connected to the first fixed part 231, meaning the first driving member 230 can rotate together with the second rotating part 242. In one embodiment (not shown), the gimbal shooting device 200 includes a first arm, which includes a first free end and a first movable end. The first free end is connected to the housing 231a, and the first movable end is connected to the first rotating part 242. The first arm, as an intermediate component, avoids interference caused by direct connection between the first driving member 240 and the second driving member 250, which would hinder adjustment of the shooting position of the camera module 220. It also facilitates the assembly and disassembly of the first driving member 240 and the second driving member 250, and makes the gimbal shooting device 200 more aesthetically pleasing.

[0036] The third driving member 250 includes a third fixed part 251 and a third rotating part 252 connected to each other. The third rotating part 252 is rotatable relative to the third fixed part 251. The rotation axis of the third rotating part 252 extends along a third direction, which can be understood as being relative to... Figure 4The direction is parallel to the Z-axis. The third rotating part 252 is connected to the second fixed part 241, meaning the second driving member 240 can rotate together with the third rotating part 252. In one embodiment, the gimbal shooting device 200 includes a second arm 260, which includes a second free end 261 and a second movable end 262. The second free end 261 is connected to the second fixed part 241, and the second movable end 262 is connected to the third rotating part 252. Thus, the second arm 260, as an intermediate connecting member, avoids interference caused by direct connection between the second driving member 240 and the third driving member 250, which would hinder adjustment of the shooting position of the camera module 220. It also facilitates the assembly and disassembly of the second driving member 240 and the third driving member 250, and makes the gimbal shooting device 200 more aesthetically pleasing.

[0037] It should be noted that the first direction is perpendicular to the second direction, the second direction is perpendicular to the third direction, and when the gimbal shooting device 200 is in a balanced state, the first direction is perpendicular to the third direction. That is, when the gimbal shooting device 200 is in a balanced state, the first, second, and third directions are perpendicular to each other in pairs. Furthermore, all three driving components mentioned above are motors, the fixed parts are the stators of the motors (including the motor housing), and the rotating parts are the rotors of the motors. Each rotating part can rotate 360 ​​degrees relative to the fixed part. Moreover, the rotating part can rotate automatically under electronic control, or it can be driven to rotate by external force (such as manual operation) when the motor is off.

[0038] In other embodiments, the gimbal shooting device 200 can also achieve dual-axis stabilization, in which case the third drive member 250 can be omitted. Alternatively, when the gimbal shooting device 200 only needs to achieve single-axis stabilization, both the second drive member 240 and the third drive member 250 can be omitted, and the first drive member 230 and the camera module 220 form a drive mechanism assembly for achieving single-axis stabilization.

[0039] In one embodiment, the first driving member 230 includes a housing 231a, a stator 231b, and a rotor. The housing 231a and stator 231b constitute the first fixed part 231, and the rotor constitutes the first rotating part 232. The stator 231b is disposed within the housing 231a, and the rotor has a hollow structure and is rotatably disposed within the stator 231b. In one embodiment, the stator 231b includes an enameled wire 233 (equivalent to an outer magnet) and a stator core 234 sleeved on the enameled wire 233. The rotor includes an inner magnet disposed inside the enameled wire 233. Thus, the rotor can be driven to rotate through the magnetic interaction between the inner magnet and the outer magnet.

[0040] The camera module 220 is disposed within and fixedly connected to the rotor. In one embodiment, the camera module 220 includes a photosensitive component 221 and a lens assembly 222. The lens assembly 222 is disposed in the photosensitive path of the photosensitive component 221. The lens assembly 222 includes a lens mount 223 and a lens 224 disposed within the lens mount 223. The rotor is fitted onto the lens mount 223. Thus, the rotation of the rotor can drive the rotation of the lens mount 223, thereby achieving synchronous rotation of the camera module 220 and the rotor. The lens mount 223 and even the lens 224 disposed within the lens mount 223 are equivalent to the output shaft of the first driving member 230. The camera module 220 being built into the first driving member 230 reduces the thickness of the entire device. In one embodiment, the photosensitive component 221 includes a circuit board 221a and a photosensitive chip 221b. The photosensitive chip 221b is disposed on and electrically connected to the circuit board 221a. The lens mount 223 includes a base body 223a and a barrel body 223b. The base body 223a is connected to the circuit board 221a and surrounds the photosensitive chip 221b. The barrel body 223b is disposed at the end of the base body 223a away from the circuit board 221a. A rotor is sleeved on the barrel body 223b. In one embodiment, the central axis of the lens 224 coincides with the rotation axis of the rotor, that is, the camera module 220 and the rotor rotate coaxially.

[0041] In one embodiment, the first driving member 230 includes bushings 235 connected to both ends of the housing 231a, and bearings 236 connected to the inner rings of the bushings 235, with the cylinder 223b passing through the bearings 236. Thus, the bearings 236 can support the cylinder 233b and reduce the coefficient of friction of the cylinder 223b during rotation, ensuring its rotational accuracy. The bearings 236 can be sliding bearings or rolling bearings.

[0042] In one embodiment, the drive mechanism assembly includes a washer 237, which is sleeved on the cylinder 223b and sandwiched between the rotor and the base 223a to reduce wear on the cylinder 223b during rotation and to achieve shock absorption. The washer 237 can be, but is not limited to, elastic washers such as plastic washers or silicone washers.

[0043] In the aforementioned gimbal shooting device 200, the camera module 220 is housed within the rotor and fixedly connected to it. This allows the camera module 220 to rotate synchronously under the rotor's drive, achieving physical image stabilization and improving the stability of the images captured by the camera module 220. Since the camera module 220 is integrated into the first driving component 230 (e.g., a motor), compared to the prior art where the motor and camera module are separate, the overall thickness of the device is reduced, resulting in a smaller size and easier portability.

[0044] In one embodiment, the gimbal shooting device 200 includes a motion detection module and a processor. The motion detection module can be a gyroscope, which can be mounted on a lens mount to rotate synchronously with the lens mount. The motion detection module is connected to the processor and can send the azimuth angle change of the camera module to the processor. The processor is connected to the first drive unit 230, the second drive unit 240, and the third drive unit 250 respectively, and can control the rotation angle of the first drive unit 230, the second drive unit 240, and the third drive unit 250 according to the detection result of the motion detection module.

[0045] When using the gimbal shooting device 200 or the shooting terminal 10, if the user changes the shooting orientation, the azimuth angle of the motion detection module's own axis will change accordingly. Simultaneously, the motion detection module sends the azimuth angle change signal to the processor. The processor can calculate the required rotation angles for the first rotating part 232, the second rotating part 242, and the third rotating part 252 based on an algorithm. The rotation directions of the first rotating part 232, the second rotating part 242, and the third rotating part 252 are all opposite to the directions corresponding to the azimuth angle of the motion detection module's own axis. Thus, even if the gimbal shooting device 200 or the shooting terminal 10 is moving, the camera module 220 remains in its initial position, ensuring shooting stability.

[0046] In one embodiment, the gimbal shooting device 200 further includes a motherboard 270 and a button assembly (not shown). The button assembly can be disposed on the outer surface of the body 100. The button assembly is connected to the motherboard 270 and can send action commands to the motherboard 270. The motherboard 270 is connected to the first drive unit 230, the second drive unit 240, and the third drive unit 250 respectively, and can control the rotation angle of the first rotating part 232, the rotation angle of the second rotating part 242, and the rotation angle of the third rotating part 252 according to the action commands.

[0047] In one embodiment, the button assembly may include a power button, a joystick, and function buttons. The power button controls the on / off state of the gimbal shooting device 200 and switches between the photo and video recording functions of the camera module 220. The joystick controls the orientation of the camera module 220, such as its roll (driven by the first drive member 230), pitch (driven by the second drive member 240), and yaw (driven by the third drive member 250). Multiple function buttons may be provided; some may be used to adjust the shooting focal length of the camera module 220, while others may be used to control the operating modes of various drive members, such as lock and follow modes. It should be noted that the number of buttons included in the button assembly and the functions of each button can be determined according to actual usage requirements and are not limited here.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
