Through the screen rotation structure, sensor detection and gimbal coordinated control, it automatically triggers the horizontal and vertical switching of the lens, realizing intelligent switching of the lens horizontal / vertical shooting mode, reducing reliance on mechanical buttons, improving equipment durability, and ensuring gimbal stability, thereby enhancing the live broadcast and shooting experience.

Figure 4 This is a schematic diagram of a magnet provided in an embodiment of the present application.

[0040] like Figure 1 、 Figure 2 and Figure 3 As shown, a handheld gimbal camera includes: a screen bracket 100, a screen connector 200, a rotating mechanism, a body, a micro switch and a controller; the micro switch includes: a first micro switch 510 and a second micro switch 520; wherein, the screen bracket 100 is fixed to the rotating mechanism through the screen connector 200; a first limiting rib 410 and a second limiting rib 420 are provided on the front shell of the handle of the body, and the first micro switch 510 is provided on the side of the first limiting rib 410 close to the second limiting rib 420, and the second limiting rib 420 close to the first limiting rib 410. A second micro switch 520 is provided on one side of 0; a protrusion structure 310 is provided on the rotating mechanism, and when the rotating mechanism rotates, the protrusion structure 310 is limited between the first limiting rib 410 and the second limiting rib 420; when the protrusion structure 310 moves to the position where the limiting rib is located, the micro switch generates a trigger signal; after receiving the trigger signal, the controller determines the target shooting mode according to the trigger signal; drives the motor to move according to the target shooting mode, so that the lens rotates to the direction corresponding to the target shooting mode; and switches the display interface mode of the screen according to the target shooting mode.

[0041] Furthermore, the handheld gimbal camera also includes a handheld portion.

[0042] In the embodiment of the present application, the screen bracket 100 is used to fix and support the screen 600. The screen bracket 100 has a snap-fit ​​structure, which can fix the screen between the screens.

[0043] The screen connector 200 fixedly connects the screen bracket 100 to the rotating mechanism, so that the screen fixed on the screen bracket 100 can rotate along with the rotating mechanism.

[0044] The rotating mechanism is used to realize multi-directional rotation of the screen, so that the screen can be rotated to different shooting angles. A protruding structure 310 is provided on the rotating mechanism. Generally, the rotating mechanism is set in a ring shape to facilitate rotation.

[0045] The body is the main structure of the gimbal camera. The first limiting rib 410 and the second limiting rib 420 (two raised mechanical blocks) are set on the front shell of the handle of the body. The first limiting rib 410 and the second limiting rib 420 are fixed in the position of the gimbal camera. The two can form an arc of about 90 degrees, such as Figure 5 As shown, A and B are the positions of the first limiting rib 410 and the second limiting rib 420 respectively.

[0046] The first limiting rib 410 and the second limiting rib 420 are used to limit the rotation range of the rotating mechanism, that is, when the rotating mechanism moves, the protruding structure 310 is driven to move between the first limiting rib 410 and the second limiting rib 420 .

[0047] A first micro switch 510 is provided on one side of the first limiting rib 410 close to the second limiting rib 420. Figure 3 As shown, in the direction of the screen, the first microswitch 510 and the plane containing the protruding structure 310 are parallel, so that the first microswitch 510 does not affect the movement of the protruding structure 310. During movement, the protruding structure 310 passes over the first microswitch 510 and reaches the position of the first limiting rib 410, where it is restrained by the first limiting rib 410. Similarly, a second microswitch 520 is provided on the side of the second limiting rib 420 near the first limiting rib 410; in the direction of the screen, the second microswitch 520 and the plane containing the protruding structure 310 are parallel, so that the second microswitch 520 does not affect the movement of the rotating mechanism. Furthermore, when the rotating mechanism rotates, the protruding structure 310 is restrained between the first limiting rib 410 and the second limiting rib 420.

[0048] When the rotating mechanism rotates, the protrusion 310 moves with it. When it reaches the limit position (touches a certain limit rib), it triggers the micro switch (for example, when the protrusion 310 touches the first limit rib 410, it triggers the first micro switch 510; when it touches the second limit rib 420, it triggers the second micro switch 520). The micro switch generates an electrical signal (trigger signal) and sends it to the controller. Figure 2 When the raised structure 310 of the rotating connector 1 is rotated to the 0° and 90° positions, the micro switch is pressed to trigger the IO signal.

[0049] After receiving the trigger signal, the controller determines the target shooting mode according to the trigger signal; drives the motor to move according to the target shooting mode, so that the lens rotates to the direction corresponding to the target shooting mode; and converts the display interface mode of the screen according to the target shooting mode.

[0050] Specifically, after the IO trigger signals are generated at the two positions, the controller determines the target shooting mode to be switched based on the source of the trigger signals. Based on the target shooting mode, the controller drives the motor in the rotation mechanism to rotate the lens to the direction that matches the mode. Simultaneously, the controller controls the synchronous switching of the screen's display interface mode.

[0051] Specifically, when the rotating mechanism rotates, the protruding structure 310 moves with it. When it reaches its limit position (touching a stop rib), it triggers a microswitch (for example, when the protruding structure 310 contacts the first stop rib 410, it triggers the first microswitch 510; when it contacts the second stop rib 420, it triggers the second microswitch 520). The microswitch generates an electrical signal (trigger signal) and transmits it to the controller. Based on the source of the trigger signal (first microswitch 510 or second microswitch 520), the controller determines the current target shooting mode to be switched. For example, triggering the first microswitch 510 corresponds to portrait shooting mode, while triggering the second microswitch 520 corresponds to landscape shooting mode. Based on the target shooting mode, the controller drives the motor in the rotating mechanism to rotate the lens to the orientation that matches the mode. Simultaneously, the controller controls the screen's display interface mode to switch synchronously. That is, if the camera is in landscape shooting mode, the screen's display interface mode will be landscape. This will cause the screen to immediately switch to the corresponding UI interface in landscape or portrait orientation, and the gimbal's R-axis will switch to the corresponding angle position.

[0052] It can be seen that in the embodiment of the present application, when the screen moves, the rotating mechanism drives the protruding mechanism to move between the limit ribs. According to the trigger signal generated by the micro switch, the shooting mode is automatically confirmed and the lens automatically rotates when the motor moves, and the screen display interface automatically switches. The screen switching and lens switching methods are simple, and the lens shooting mode can be switched accurately and quickly.

[0053] Further, such as Figure 1 As shown, the rotating mechanism includes: a first rotating connector 320, a second rotating connector 330, a magnet 340 and a fixing member 350; the magnet 340 includes a first annular magnet 341 and a second annular magnet 342, the first annular magnet 341 and the second annular magnet 342 are nested, and the first annular magnet 341 is located on the inner side of the second annular magnet 342; the first rotating connector 320 and the second rotating connector 330 are arranged relative to each other to form a cavity, and the first annular magnet 341 and the second annular magnet 342 are arranged in the cavity; the first annular magnet 341 and the first rotating connector 320 are fixedly connected, and the second annular magnet 342 and the second rotating connector 330 are fixedly connected; the fixing member is fixed on the first rotating connector 320; the second rotating connector 330 is fixedly connected to the front shell of the handle.

[0054] The second rotating connector 330 can be fixed to the front shell of the handle by screws to keep the second rotating connector 330 fixed and not moving.

[0055] The first rotating connector 320 and the second rotating connector 330 are arranged opposite to each other to form a cavity, in which the first annular magnet 341 and the second annular magnet 342 are mounted. The first annular magnet 341 is closer to the rotating axis than the second annular magnet 342, that is, the first annular magnet 341 is an inner ring magnet.

[0056] The second annular magnet 342 is fixedly connected to the second rotating connector 330, so that the second annular magnet 342 is fixed to the body and does not move. The second annular magnet 342 can be fixed to the second rotating connector 330 by glue.

[0057] The first annular magnet 341 is fixedly connected to the first rotating connector 320. When the screen rotates, the screen connector 200 drives the first rotating structure to rotate, causing the first annular magnet 341 and the first rotating member to move. The first annular magnet 341 can be fixed to the first rotating connector 320 by adhesive. A protrusion structure 310 is fixedly provided on the first rotating connector 320. When the screen moves, the screen connector 200 drives the first rotating connector 320 to move, allowing the protrusion structure 310 on the first rotating connector 320 to move between the first limiting rib 410 and the second limiting rib 420.

[0058] The fixing member is fixed to the first rotating connector 320, and the second rotating connector 330 and the magnet are limited between the first rotating connector 320 and the fixing member 350 through the fixing member 350. Among them, the fixing member 350 is a rotating top cover. Furthermore, the rotating top cover is fixedly connected to the first rotating connector 320 by threads. The rotating top cover is fixed to the first rotating connector 320, limiting the second rotating connector 330 and the magnet to the middle, ensuring the rotation gap while performing the upper and lower limiting functions. The second rotating connector 330 is screwed to the front shell of the handle, and finally the screen is rotated along the center axis with the first rotating connector 320 and the first annular magnet 341.

[0059] like Figure 2 A first limiting rib 410 and a second limiting rib 420 are designed on the front shell of the handle, and a protruding structure 310 is provided on the first rotating connector 320, which is limited by the first limiting rib 410 and the second limiting rib 420 when it reaches the 0° and 90° positions.

[0060] by Figure 2 For example, the vertical screen state is shown, and the relative magnetic pole relationship of the first annular magnet 341 and the second annular magnet 342 can be Figure 4 The relative position of the portrait state shown in .

[0061] Further, yes Figure 4To explain, since the first annular magnet 341 (inner ring magnet) is fixed to the first rotating connector 320, and the second annular magnet 342 (outer ring magnet) is fixed to the second rotating connector 330, the first annular magnet 341 moves through the movement of the first rotating connector 320. The first rotating connector 320 is provided with a protruding structure 310, and the first limiting rib 410 and the second limiting rib 420 are designed on the front shell of the handle, both of which are located outside the first rotating connector 320. For ease of understanding, Figure 4 In the figure, the two large squares are limit ribs and the small square is a protruding structure 310. Figure 4 This diagram is for illustrative purposes only and is not an actual structural diagram. The position of the limiting rib remains unchanged, while the inner ring magnet can move and drive the raised mechanism to move.

[0062] like Figure 4 , using the principle of mutual repulsion between like poles of magnets, the magnets provide an outward repulsive force to achieve hovering in horizontal and vertical positions. Specifically, the magnets are designed with N and S poles distributed on both sides by axial magnetization. Mark the structural parts and also mark the N pole of the magnet. When fixing, the N pole needs to be fixed to a specified angle position. When rotated to the 45-degree position, the two like poles overlap, and both positive and negative rotations provide repulsive force. Hovering is possible after limiting the 0 and 90° positions.

[0063] In one possible scenario, when the screen rotates, a microswitch triggers a mode switch. The microswitch has three stages: an initial position, where the microswitch is pressed and triggered, typically in portrait or landscape mode; a rotation where neither microswitches are triggered; and a final position, where the microswitch is pressed and triggered. The first two stages remain in the initial state. That is, if the initial state is landscape mode, then landscape mode will be displayed from the moment the microswitch is pressed to the second moment when both switches are deactivated. The screen's UI and gimbal will switch to portrait mode after the microswitch is triggered. Alternatively, the screen's UI and gimbal will remain in landscape mode after the microswitch is triggered. Upon receiving the signal, the controller immediately displays the UI for the corresponding mode and controls the motor to rotate the lens to the corresponding orientation (horizontal for landscape mode, vertical for portrait mode).

[0064] The screen switching duration is shorter than the gimbal rotation duration. Furthermore, in one achievable method, the controller can switch the screen's display interface mode based on the target shooting mode and pause the screen's display interface until the lens rotation is complete. For example, a screen switch takes only 100ms, while a gimbal rotation takes 500ms. During the 100ms screen switch, the screen display will briefly freeze, followed by a 400ms display of the real-time gimbal rotation. However, the actual recorded image is the complete 500ms real-time switching process from one mode to another. The 100ms screen switching delay is only reflected in the on-screen UI display. For example, when switching from landscape to portrait mode, the screen displays a brief 100ms switching animation (with a slight pause on the display) followed by a 400ms rotation of the lens. However, when exported and viewed on other devices such as mobile phones or computers, the complete 500ms rotation image is seamless.

[0065] In one feasible way, the present application is provided with an anti-false touch mechanism. After the controller receives the trigger signal generated by the micro switch, if it does not receive a new trigger signal within the preset time interval, the target shooting mode is determined according to the trigger signal. There are two micro switches in the present application, and there are three states: horizontal screen state, vertical screen state and intermediate state (the intermediate state is the same as the initial state). In specific scenarios, such as when the screen is stuck on the clothes and the trigger switch is turned 90° and then manually turned back, the screen switches twice, and the gimbal switches halfway and then switches back, which affects the experience. Furthermore, the present application can add a delayed response (such as switching within 0.5 seconds when the angle is stable) to avoid false triggering due to jitter.

[0066] In one achievable manner, the gimbal of the present application can be fast and stable during the switching process. Furthermore, the controller can also determine the motion information of the motor movement, which includes the acceleration information of each time period; according to the target shooting mode, the motor is driven according to the motion information. Specifically, the motion segmentation feature: the rotation from 0° to 90° is divided into 6 stages: acceleration stage, uniform acceleration stage, deceleration stage, acceleration and deceleration stage, uniform deceleration stage, and deceleration and deceleration stage, to ensure continuous change of acceleration.

[0067] Based on the above, it can be seen that the hardware structure design of this application includes: a structure for connecting the screen to the rotating mechanism, a fixing structure for the screen rotating mechanism, a fixing structure for the magnet, a limiting structure for the rotating mechanism, a mechanism for triggering the micro switch of the rotating mechanism, etc. Among them, the rotatable screen is connected to the body through a hinge, supports 0° (vertical screen) and 90° (horizontal screen) rotation, and can hover in the horizontal and vertical positions. The rotation detection module, the micro switch can detect rotation. The physical trigger switch, when the screen is rotated to a specific angle, press the micro switch to confirm the mode switch. Furthermore, it can also include: a three-axis gimbal system, pitch (Pitch), roll (Roll), and yaw (Yaw) axis motors to adjust the lens direction according to the screen angle.

[0068] The software control logic of this application includes the following: Detection phase: When the screen rotates, the microswitch provides real-time feedback of a trigger signal, triggering the mode switch. Judgment phase: Based on the microswitch signal detection, if the landscape mode trigger switch is triggered, the screen is in landscape mode; if the portrait mode trigger switch is triggered, the screen is in portrait mode. Execution phase: The gimbal controls the motor to rotate the lens to the corresponding orientation (horizontal for landscape mode, vertical for portrait mode).

[0069] Furthermore, the force provided by the magnet is combined with the axial / rotational limit structure to achieve physical rotation and hovering; combined with a simple hardware IO trigger mechanism, it not only meets the low-power trigger function but also prevents accidental touches.

[0070] The present invention provides a method for switching shooting modes of a handheld gimbal camera. Figure 6 As shown, the method provided in the embodiment of the present application can be executed by a controller of a handheld gimbal camera, and the method for switching the shooting mode of the handheld gimbal camera includes:

[0072] When the screen mounted on the screen bracket drives the rotating mechanism to rotate, the raised structure on the rotating mechanism rotates between the first limiting rib and the second limiting rib. A first micro switch is provided on the side of the first limiting rib close to the second limiting rib, and a second micro switch 520 is provided on the side of the second limiting rib close to the first limiting rib. When the raised structure moves to the position where the micro switch is located, the micro switch generates a trigger signal.

[0073] The trigger signal refers to an electrical signal generated by the micro switch, which is used to indicate that the raised structure of the rotating mechanism has reached a specific position.

[0074] In some embodiments, when the user rotates the screen from portrait to landscape, the rotation mechanism drives the raised structure to move from the first limiting rib to the second limiting rib. When the raised structure touches the second micro switch 520 on the side of the second limiting rib, the switch contacts close, generating a high-level trigger signal that is transmitted to the controller.

[0075] S102, determining a target shooting mode according to a trigger signal;

[0076] In one achievable method, the identification information of the micro switch corresponding to the trigger signal is determined; the target shooting mode is determined according to the identification information and a preset corresponding relationship, where the preset corresponding relationship is the corresponding relationship between the identification information and the shooting mode. Figure 2 For example, when the raised structure moves to the first microswitch, the corresponding shooting mode is portrait mode. When the raised structure moves to the second microswitch 520, the corresponding shooting mode is landscape mode. Therefore, based on the identification information of the microswitch corresponding to the trigger signal, it is possible to determine whether the microswitch sending the trigger signal is the microswitch corresponding to the landscape mode or the microswitch corresponding to the portrait mode.

[0077] In one possible scenario, the trigger signal of the micro switch corresponding to the landscape shooting mode is a rising edge, while the trigger signal of the micro switch corresponding to the portrait shooting mode is a falling edge, so that the corresponding identification information can be determined. Other technologies can also be used for implementation, which is not limited here.

[0078] S103 , driving the motor to move according to the target shooting mode, so that the lens rotates to a direction corresponding to the target shooting mode; and switching the display interface mode of the screen according to the target shooting mode.

[0079] It can be seen that in the embodiment of the present application, when the screen moves, the rotating mechanism drives the protruding mechanism to move between the limit ribs. According to the trigger signal generated by the micro switch, the shooting mode is automatically confirmed and the lens automatically rotates when the motor moves, and the screen display interface automatically switches. The screen switching and lens switching methods are simple, and the lens shooting mode can be switched accurately and quickly.

[0080] A possible implementation of an embodiment of the present application is to determine the target shooting mode according to a trigger signal, including: after receiving a trigger signal generated by a micro switch, if no new trigger signal is received within a preset time interval, determining the target shooting mode according to the trigger signal.

[0081] The preset duration is a time window used to determine the validity of the trigger signal, typically 100ms-2s. It distinguishes valid triggers from false triggers. If no new signal is received within the preset duration, it is considered a valid trigger; if signals are continuously received, it is considered a false trigger.

[0082] A possible implementation method of an embodiment of the present application is to convert the display interface mode of the screen according to the target shooting mode, including: converting the display interface mode of the screen according to the target shooting mode, and pausing the image of the display interface of the screen until the lens rotation is completed.

[0083] The screen's display interface is converted to the display interface corresponding to the target shooting mode. At the same time, since the lens needs to be flipped, if the screen displays the image during rotation, the user experience is poor. Therefore, in an embodiment of the present application, the screen freezes the current display content during lens rotation. When the lens rotation is completed, the interface is synchronously displayed according to the updated mode. The screen pause function avoids screen display confusion during lens rotation, and the user perceives a smoother interface switching process.

[0084] One possible implementation of the present invention further includes storing video captured by a handheld gimbal camera, including footage captured during lens rotation. In a real-time display interface, the current display content is frozen during the rotation process, while backend storage continues to calculate and store footage captured during the lens rotation process, allowing users to access information from the entire process and facilitating traceability.

[0085] A possible implementation of the embodiment of the present application is to drive the motor to move according to the target shooting mode, including: determining motion information of the motor movement, the motion information including acceleration information of each time period; and driving the motor to move according to the motion information according to the target shooting mode.

[0086] Motor motion information refers to a set of quantitative parameters that describe how the motor's motion changes over time during lens rotation. This information includes acceleration information for multiple time periods. For example, within the gimbal's 0° to 90° rotation range, the entire rotation process is divided into six stages: acceleration, uniform acceleration, deceleration, acceleration and deceleration, uniform deceleration, and deceleration. This segmented approach allows for continuous acceleration changes, ensuring smooth motor motion.

[0087] In the acceleration phase, acceleration gradually increases from 0, allowing the motor to accelerate smoothly and avoid sudden impact. The rate of acceleration increase can be determined based on the motor's performance parameters (maximum acceleration, starting torque) and the requirements of the rotation process. In the uniform acceleration phase, when the acceleration reaches an appropriate value, the motor enters the uniform acceleration phase, accelerating at a steady rate. In the deceleration phase, acceleration is reduced to ensure a smooth transition to the deceleration phase. In the acceleration / deceleration phase, negative acceleration (i.e., deceleration) is applied, and this negative acceleration gradually increases. In the uniform deceleration phase, when the negative acceleration reaches a certain value, the motor enters the uniform deceleration phase, decelerating at a constant negative acceleration. In the deceleration phase, when approaching the final target position, the negative acceleration is further reduced to allow the motor to stop smoothly. The speeds of each of these phases can be matched to the desired motion duration using pre-stored motor motion information.

[0088] When the motor receives the drive signal, it starts to accelerate, gradually increasing at a preset acceleration rate. During this process, the motor speed slowly increases from 0, and the gimbal also begins to slowly rotate. During the motion process, the encoder can constantly monitor the motor speed and acceleration to ensure accurate acceleration. Furthermore, the entire motion process is evaluated and the motion information is recorded for subsequent optimization and adjustment.
