[0046] Specifically, the embodiment of the present application adopts a dual-axis design, that is, two motors are used to control different rotation axes, one for the horizontal direction (left and right rotation) and the other for the vertical direction (forward and backward direction, nodding action). The motor is a precision stepper motor or servo motor, which can provide accurate angle control, making the rotation of the holographic display screen more precise and smooth.

[0047] Among them, the control module is a microcontroller (MCU), that is, a single-chip computer. The microcontroller is used to control the operating status of the motor, including speed, direction and stop position. The MCU can also implement complex control algorithms, such as PID control, to optimize performance.

[0048] The embodiment of the present application also includes a position sensor, which is installed (such as an optical encoder) to monitor the angular position of the holographic display screen in real time to ensure precise control of the rotation angle.

[0049] The pluggable display device provided in the embodiment of the present application is a combination of a display device (head component) and a multi-functional base (base component). The display device can be a holographic display mode or a naked-eye 3D display mode, or an ordinary display screen is not limited to a holographic display.

[0050] The pluggable display device provided in the embodiment of the present application needs to have sufficient structural strength and stability to support the holographic display screen and ensure stability during rotation, and have a flexible connection mechanism. A flexible connection mechanism (such as a ball joint or a universal joint) is designed to support free rotation while reducing structural restrictions.

[0051] In addition, the base can identify the type of connected device and automatically switch to the appropriate working mode, that is, intelligent mode switching, whether it is providing navigation information in car mode or providing entertainment content in home mode.

[0053] In the above implementation process, by connecting the head component and the base component by magnetic attraction, it is not only easy to install and move quickly, but also greatly improves the portability and flexibility of use of the device. At the same time, motors are installed in the head component and the base component respectively to control the head component to nod or turn left and right, respectively, providing users with rich interaction methods and personalized services, and improving users' immersion and satisfaction.

[0059] In some embodiments of the present application, a rotating pan-tilt head is provided in the base assembly and connected to the head assembly, and the first data transmission interface in the rotating pan-tilt head is connected to the first data transmission interface of the head assembly through an elastic mechanism or a slide rail structure in the rotating pan-tilt head, power supply and data transmission are realized through a single interface, and advanced encryption technology is used to protect the data transmission process, thereby ensuring that the user's privacy and information security are fully guaranteed.

[0060] like Figure 4 As shown, optionally, a magnet 10 is arranged on the top of the rotating pan-tilt head, and a metal sheet or magnet 09 is arranged on the bottom of the head assembly, corresponding to the magnet of the rotating pan-tilt head.

[0069] like Figure 8 As shown, in some embodiments of the present application, when the position of the notch 15 on the rotating gimbal moves to the position of the inductive limit switch, the inductive limit switch will trigger a signal, and the angular position of the gimbal can be known, thereby controlling the rotation angle of the entire head assembly.

[0070] Specifically, the base assembly adopts an advanced motor structure, which not only supports the left and right rotation of the holographic display, but also adds a nodding action. This structure allows the holographic display to be dynamically adjusted in both vertical and horizontal directions, covering a certain angle, bringing users a more flexible and more humanized interactive experience.

[0071] With the introduction of the "nod" function, the holographic display can now realize similar "nod" actions, which increases the fun and intuitiveness of the interaction.

[0078] Optionally, the first motor 04 or the second motor 05 at least includes a stepper motor or a servo motor.

[0079] Optionally, a camera 20 is also provided on the head component, and the camera 20 is used to obtain the user's expression information.

[0080] The top camera in this application supports advanced visual tracking capabilities, which can capture the user's facial and eye movements in real time to achieve natural and humanized interaction. This dynamic interaction method not only allows the device to respond more accurately to the user's viewing direction and focus, but also brings revolutionary improvements to the interactive experience, making the user's interaction with the device more natural and intuitive.

[0081] Optionally, the head assembly is further provided with an ambient light sensor 19, which is used to obtain lighting information.

[0082] The head assembly is also equipped with an ambient light sensor that can automatically adjust the display brightness according to the surrounding light conditions to ensure clear visual effects in different lighting environments.
