Technical Field

[0001] This invention relates to the field of dance practice cabinet technology, and in particular to an intelligent dance practice cabinet with audio-visual playback and projection mirror functions, and its usage method. Background Technology

[0002] Dance students need to practice repeatedly after class to solidify their learned movements. Traditional practice methods usually require finding a large enough mirror at home and preparing additional devices such as TVs, tablets, or mobile phones to play instructional videos and music. This method has several obvious drawbacks: First, the mirror and playback device are separate, taking up a lot of space and being inconvenient to arrange; second, ordinary wall-mounted or floor-standing mirrors do not have folding or expansion functions, still occupying indoor space when not in use, affecting the aesthetics and space utilization of the room; finally, existing multi-functional mirror cabinet products are mostly single-function, with the mirror being non-adjustable or having a limited adjustment range, failing to provide dancers with a multi-angle observation field of view, and lacking an intelligent interactive experience. Therefore, this invention proposes an intelligent dance practice cabinet with audio-visual playback and mirror expansion functions, along with its usage method, to solve the above problems.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-6 The intelligent dance practice cabinet with audio-visual playback and mirror display functions includes cabinet body 1, mirror component 2, audio-visual playback module 3 and control module 4; Among them, cabinet 1 is a rectangular structure, and the material is high-density board or metal alloy to ensure structural stability and durability; The mirror assembly 2 includes a main mirror 201 and at least two secondary mirrors 202. The main mirror 201 is connected to the top of the cabinet 1 via a flipping mechanism 5. The secondary mirrors 202 are connected to the two sides of the cabinet 1 via double-axis hinges 6. When the main mirror 201 is folded, it is close to the bottom surface of the top plate of the cabinet 1. When the secondary mirrors 202 are closed, they cover the sides of the cabinet 1 like cabinet doors. The outer surface is the same color as the cabinet 1, forming a unified appearance. This arrangement makes the device look simple when stored and does not take up extra space. When unfolded, it provides all-round mirror reflection and multimedia support, which is beneficial to the convenience and efficiency of dance practice. The audio-visual playback module 3 includes a display screen 301, a USB interface, and an audio output device; Among them, the display screen 301 is an LCD display screen 301, which is embedded in the center of the front of the cabinet 1 and is used to display videos, music lists and operation interfaces. The USB interface is located on the side of the cabinet 1 and is used to import external content. The control module 4 includes a controller and an operation panel 401. The controller is used to control the unfolding and folding of the main mirror 201 of the mirror assembly 2 and the playback and switching of audio-visual content of the audio-visual playback module 3. The controller is an STM32 microcontroller.

[0019] In this embodiment, the flipping mechanism 5 includes a rotating shaft 501 set on the top of the main mirror 201, a bushing 502 set on the bottom of the top plate of the cabinet 1, and a stepper motor 503 set on the top of the top plate of the cabinet 1 for driving the rotating shaft 501 to rotate. Two bushings 502 are provided. A rotating shaft 501 is inserted into the bushing 502. A first synchronous pulley 504 is provided at one end of the rotating shaft 501. A second synchronous pulley 505 is provided on the output shaft of the stepper motor 503. A synchronous belt 506 is fitted on the first synchronous pulley 504 and the second synchronous pulley 505. The first synchronous pulley 504 and the second synchronous pulley 505 rotate synchronously through the synchronous belt 506. The flipping mechanism 5 also includes a position encoder 507, an electromagnetic brake, and a damper 508. The position encoder 507 and the damper 508 are located at the other end of the rotating shaft 501 away from the first synchronous pulley 504. Specifically, the position encoder 507 and the damper 508 are mounted on the top plate side of the cabinet 1 via a support plate, and the electromagnetic brake is located on the output shaft of the stepper motor 503. The stepper motor 503, position encoder 507, electromagnetic brake and damper 508 are electrically connected to the controller. The damper 508 is used to provide damping force to the rotating shaft 501, so that the rotating shaft 501 can move smoothly and avoid damage caused by sudden movement. At the same time, the electronically adjustable damping coefficient allows users to adjust the unfolding speed as needed, improving the safety and comfort of operation. The position encoder 507 is used to monitor the unfolding angle of the main mirror 201, and the electromagnetic brake is used to lock the position when the main mirror 201 unfolds to the required angle. The damping coefficient of the damper 508 can be electronically adjusted by an STM32 microcontroller, for example, by adjusting the current to achieve a damping range of 0-5 N·m. The position encoder 507 is used to monitor the unfolding angle of the main mirror 201 in real time and transmit the data to the display screen 301 for display.

[0020] When the main mirror 201 unfolds to a preset value, such as a 90-degree vertical position, the angle sensor sends a stop signal to the STM32 microcontroller, the stepper motor 503 stops rotating and locks the current position through the electromagnetic brake; The electromagnetic brake is a disc brake, controlled by an STM32 microcontroller, which ensures that the main mirror 201 is stably positioned after unfolding and is not easy to shake, which is beneficial to the stability of the mirror during dance practice.

[0021] In this embodiment, vertical shafts 7 are provided on both sides of the cabinet 1, one side of the double-axis hinge 6 is rotatably connected to the vertical shaft 7, and the other side of the double-axis hinge 6 is rotatably connected to the horizontal shaft 8. The double-axis hinge 6 is connected to the secondary mirror 202 through the horizontal shaft 8. The dual-axis hinge 6 rotates along the vertical axis 7, allowing the secondary mirror 202 to unfold horizontally by 180 degrees. The horizontal axis 8 of the dual-axis hinge 6 rotates, allowing the secondary mirror 202 to tilt vertically by ±30 degrees; A limit bolt 9 is provided on the dual-axis hinge 6, and the dual-axis hinge 6 is locked by the limit bolt 9 when the secondary mirror 202 is unfolded to the required angle. An angle sensor, which is a Hall sensor, can be installed on the dual-axis hinge 6 and is electrically connected to the STM32 microcontroller to display the unfolding angle of the secondary mirror 202.

[0022] This structure allows the secondary mirror 202 to open and close like a door, forming a three-sided mirror system when unfolded. This provides multi-angle reflections, which is beneficial for dance students to observe the details of their own movements. At the same time, the limiting buckle prevents accidental closure and improves the safety of use.

[0023] In this embodiment, the cabinet 1 is provided with several adjustable partitions 10. Two parallel guide rails 11 are provided on both sides of the inner wall of the cabinet 1. Two sliders 12 are provided on both sides of the partitions 10. The sliders 12 of the partitions 10 are slidably mounted on the guide rails 11. The slider 12 of the partition 10 is equipped with a latching mechanism, which locks the slider 12 to position the partition 10. The latching mechanism is a spring-loaded latch, which can release the partition 10 after pressing. Users can adjust the space inside the cabinet as needed to store dance supplies or other items. When the mirror is not in use, it can be used as a storage cabinet, which is beneficial to the efficiency of space utilization.

[0024] In this embodiment, the display screen 301, USB interface, audio output device and operation panel 401 are all electrically connected to the controller. The operation panel 401 includes a power button, a video playback button, a music playback button, an up button and a down button. The operation panel 401 is also equipped with an infrared sensing module. The power button is electrically connected to the infrared sensing module and is used to automatically trigger the power-on when a human body is detected approaching. The display screen 301 integrates touch function to replace some physical button operations. For example, you can directly select videos or adjust the volume through the touch screen. The STM32 microcontroller is installed in a hidden position at the bottom of the cabinet 1 and is integrated with the circuit board. The circuit board is connected to a USB interface to read the contents of the memory and ensure that the audio-visual functions and mechanical unfolding are coordinated. For example, after powering on, the unfolding of the main mirror 201 can be controlled through the touch screen. The position encoder 507 feeds back data to the display screen 301 to realize closed-loop control. This integration improves the interactivity of the device and helps users seamlessly switch dance content during practice. The infrared sensing module, comprising a transmitter and a receiver, is located in the center of the front of cabinet 1. When a human body is detected approaching at a distance of less than 50 centimeters, the power button is automatically triggered, enabling contactless startup. The STM32 microcontroller controls the speed of the stepper motor 503 via a PWM signal, achieving smooth adjustment of the unfolding speed of the main mirror 201, gradually changing from 0 to maximum speed. This collaborative approach allows the device to automatically prepare when the user approaches. Combined with button operations such as video and music playback buttons, imported USB videos and music can be played. Up and down buttons are used to switch content. This mechanism improves the device's intelligence level, reduces manual operation, and facilitates quick entry into practice.

[0025] In this embodiment, four casters 13 are provided at the bottom of the cabinet 1 to facilitate overall movement and allow 360-degree rotation. The casters 13 are equipped with a braking device to lock the wheels and prevent slippage, ensuring stability during use and improving the safety of dance practice.

[0026] The method of using the intelligent dance practice cabinet with audio-visual playback and projection functions of this invention includes the following steps: S1. When the power is connected, the infrared sensor module detects the proximity signal and automatically triggers the power button, and the controller starts up. S2. Select the video imported via USB interface using the touch screen or video playback button, and the controller will control the main mirror 201 to unfold. S3. Start the stepper motor 503 through the controller, so that the output shaft of the stepper motor 503 drives the second synchronous pulley 505, the synchronous belt 506 and the first synchronous pulley 504 to rotate, thereby driving the rotating shaft 501 and the main mirror 201 to rotate. S4. The position encoder 507 records the unfolding angle of the main mirror 201. When the main mirror 201 unfolds to the required angle, the controller locks the rotating shaft 501 through the electromagnetic brake to lock the position of the main mirror 201. S5. Manually open the secondary mirrors 202 on both sides of cabinet 1, adjust the horizontal and vertical angles of the secondary mirrors 202 and lock them; S6. Play the accompaniment via the touchscreen or music playback button, switch the dance content using the up and down buttons, and practice in front of the three-sided mirror; S7. After the practice session, fold the main mirror 201 and the secondary mirror 202 to restore the practice cabinet to its storage state, and use the partition 10 inside the cabinet to store items.
