[0002] A selfie device is a device used to hold a mobile phone or other shooting equipment in place and allows for adjustment of the shooting angle as needed. Currently, most selfie devices are used by users who manually adjust the shooting angle before taking the picture. For example, the phone is placed on the clip of the selfie device, and the selfie stick is swung to a suitable angle before the camera is activated manually or remotely. However, in special situations, such as when users are live streaming, they need to interact with fans and may need to change their posture or move around, leaving no time to adjust the shooting angle.

[0003] In addition, focusing currently relies on operating the shooting equipment, but in special situations such as live streaming, it is not convenient to directly operate the shooting equipment to focus. Utility Model Content

[0024] Please see Figure 1 and Figure 2 This embodiment illustrates a selfie device capable of automatic face tracking and focusing, including a handheld component 1, a clamping component 2, a motorized gimbal 3, an automatic tracking module 4, a focus knob 5, and a main controller. The handheld component 1 is rod-shaped and designed for the user to grip. The clamping component 2 is used to clamp the shooting device and is located at the top of the handheld component 1. The motorized gimbal 3 is installed between the handheld component 1 and the clamping component 2 and is used to drive the clamping component 2 and the shooting device thereon to move or rotate, thereby adjusting the orientation of the shooting device.

[0025] The automatic tracking module 4 is installed on the outer side of the clamping component 2, the focusing knob 5 is rotatably installed on the outer side of the handheld component 1, and the main controller is installed on the circuit board inside the handheld component 1. The electric gimbal 3, the automatic tracking module 4 and the focusing knob 5 are all electrically connected to the main controller.

[0026] Specifically, the automatic tracking module 4 includes a module housing 41, a camera 42, a light panel, and a light cover 43. The camera 42 is used to acquire image information in real time and feed it back to the main controller. After processing the image information, the main controller controls the motorized gimbal 3 to work based on the processing results to achieve automatic face tracking. The main controller can receive the rotation angle information of the focus knob 5, and after signal conversion and processing, control the shooting equipment to achieve focusing operation.

[0027] The light panel is installed inside the module housing 41, and the lamp cover 43 covers the side of the module housing 41 facing the user. The lamp cover 43 has a clearance hole corresponding to the position of the camera 42. Through the above design, the automatic tracking module can have an illumination function and provide supplementary lighting in dim environments.

[0028] In this embodiment, please refer to Figure 3 One end face of the module housing 41 is provided with a connection hole 411, and one end face of the clamping component 2 is equipped with a rotating shaft 6. The rotating shaft 6 passes through the connection hole 411, and the outer periphery of the rotating shaft 6 is connected to the inner wall of the connection hole 411 by an interference fit. When it is necessary to adjust the shooting angle of the camera 42 or the illumination angle of the supplementary light, the user can manually rotate the automatic tracking module 4. The automatic tracking module 4 can rotate relative to the clamping component 1 and can maintain the current posture after stopping the rotation.

[0029] In this embodiment, the rotation angle range of the automatic tracking module 4 is limited to 0 to 180 degrees. Therefore, the module housing 41 is provided with a guide protrusion 412 in the area corresponding to the outer periphery of the connection hole 411, and the clamping component 2 is provided with an arc-shaped slide rail 21 in the area corresponding to the outer periphery of the rotating shaft 6.

The guide protrusions 22 can slide within the arc-shaped slide rail 21, and the range of motion is limited by the limiting protrusions 22 at both ends.

[0030] In order to facilitate the relative rotation of the automatic tracking module 4 and the clamping component 2 without affecting the wired connection, the rotating shaft 6 in this embodiment is hollow. The circuit board inside the automatic tracking module 4 is electrically connected to the circuit board inside the clamping component 2 through the cable 7, and the cable 7 passes through the hollow rotating shaft 6.

[0031] Furthermore, in order to improve the heat dissipation speed, this embodiment also provides a plurality of heat dissipation holes 44 arranged in an array on the side of the module housing 41 facing away from the lampshade, so that the heat inside the module 4 can be quickly dissipated to the outside through the heat dissipation holes.

The stator of the Z-axis rotary motor 31 is fixedly mounted on the top of the handheld component 1. The rotor of the Z-axis rotary motor 31 is hinged to one end of the first swing arm 32, and the rotor of the Z-axis rotary motor 31 can rotate 360 ​​degrees around the Z-axis. The other end of the first swing arm 32 is connected to the stator of the X-axis rotary motor 33, and the rotor of the X-axis rotary motor 33 is connected to one end of the second swing arm 34, and the rotor of the X-axis rotary motor 33 can rotate 360 ​​degrees around the X-axis. The other end of the second swing arm 34 is connected to the stator of the Y-axis rotary motor 35, and the rotor clamping component 2 of the Y-axis rotary motor 35 is connected, allowing the rotor of the Y-axis rotary motor 35 to rotate 360 ​​degrees around the Y-axis. Through the above structural design, the electric gimbal 3 can drive the shooting device to position or rotate to the required angle, thereby achieving precise face tracking.

[0033] Please see Figure 4In this embodiment, the focus knob 5 includes a rotating wheel 51, an adjustment shaft 52, and a sensor 53. The adjustment shaft 52 is connected to the rotating wheel 51, and the sensor 53 is located at the end of the adjustment shaft 52 to sense the rotation angle of the adjustment shaft 52. By manually rotating the rotating wheel 51, the user can send the rotation angle signal to the main controller, which will convert and process the signal to control the shooting device to perform focusing operations.
