The carousel drives the rotating components through a built-in drive mechanism, and works with a movable transparent paper-cutting fixing plate to realize the dynamic display of paper-cutting patterns. Its innovation lies in replacing the traditional candle light source with electric power, avoiding fire hazards. At the same time, it supports users to change the paper-cutting patterns themselves, combining safety and fun.

[0003] However, the existing technology has the following technical defects: First, the display function is limited to static pattern rotation and there is no information explanation device corresponding to the paper-cutting content. When displaying traditional paper-cutting themes that the audience is not familiar with, it is difficult to convey the historical stories and cultural connotations behind the picture, resulting in limited artistic expression. Second, it uses a single light as the background light source and lacks dynamic dimming and color changing functions, which leaves room for improvement in terms of the technological feel and artistic diversity of the display form.

[0004] To address the shortcomings of the existing technology, this utility model provides a multimedia carousel that integrates a human body induction activation device, an EL backlight system, and a voice narration module. Through the combination of intelligent interactive design and diversified display technology, it effectively solves the technical problems of existing carousels in content interpretation and visual presentation, and realizes the organic integration of traditional paper-cutting art and modern technology.

[0005] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0032] See attached document Figure 1-6A human-sensor-activated carousel includes a light box 5, a geared motor 3, a base 1, and a controller. The base 1 is a housing, and the controller is installed inside the base 1. The four sides of the light box 5 are composed of EL light-emitting panels 6 of different colors, using red, green, blue, and yellow. Paper-cut or cut-out text can be pasted on the EL light-emitting panels 6. The bottom of the light box 5 is connected to a geared motor 3 via a coupling 4. The geared motor is a commercially available 3V micro geared motor with a speed of 3000 rpm and a reduction ratio of 100:1. The geared motor 3 is fixed to the base 1 via a motor base 2. The rotation of the geared motor 3 will drive the light box 5 to rotate. Five light-shielding plates are installed at the bottom of the light box 5, of which the second light-shielding plate 11, the third light-shielding plate 12, the fourth light-shielding plate 13, and the fifth light-shielding plate 14 are distributed in four mutually perpendicular directions within the same circumferential plane. Another first light-shielding plate 10 is installed in the same direction as the above. Within the same circumferential plane of the four light-shielding plates, at the position with the larger diameter, i.e., the first light-shielding plate 10 is located outside the other four light-shielding plates; below the position corresponding to the first light-shielding plate 10, the optical coupler bracket 7 is equipped with a first slot-type optical coupler 8 and a second slot-type optical coupler 9. The first slot-type optical coupler 8 is used in conjunction with the first light-shielding plate 10. When the light box rotates one revolution, at a certain moment, the first light-shielding plate 10 will pass through the center of the slot of the first slot-type optical coupler 8, blocking the light from the first slot-type optical coupler 8, and providing the controller with the start and end signal for the rotation of the light box 5. Below the circumference of the other four light-shielding plates, the second slot-type optical coupler 9 is used in conjunction. When the light box 5 rotates 90 degrees, one of the four light-shielding plates will pass through the center of the slot of the second slot-type optical coupler 9, blocking the light from the second slot-type optical coupler 9, and providing the controller with the start and end signal for the rotation of the light box 5 by 1 / 4 revolution, determining the stopping position of the light box 5 after each 90-degree rotation.

[0033] The controller consists of a microcontroller 15, a voice recording and playback module 16, an audio amplifier board module 22, a relay module 21, an EL board driver module 18, a human body sensor module 19, and a motor driver module 20. In this embodiment, the microcontroller 15 is an Arduino Nano, programmed using Mind+ graphical programming software. The programming steps can be found in [reference needed]. Figure 3 The block diagram and the Arduino port settings, loops, conditional statements, and interrupt routines on the Mind+ website are used.

[0034] The voice recording and playback module 16 in this embodiment is model ISD1760. The user can control the segmented recording through the recording button of the voice recording and playback module 16, and can record the required promotional language in 4 segments into the chip of the voice recording and playback module 16.

[0035] In this embodiment, the audio amplifier board module 22 is a mini amplifier module of model HXJ8002. The speaker 17 connected to it is a 4-ohm speaker, which can provide 2.5W of audio output. The audio input terminal of the audio amplifier board module 22 is connected to the speaker 17 output terminal of the voice recording and playback module 16.

[0036] The two I / O ports of the microcontroller 15 are connected to the playback control terminal PLAY and the fast forward terminal FWD of the voice recording and playback module 16 through two diodes respectively. The negative terminal of the diode is connected to the I / O port of the microcontroller 15. When the I / O port connected to the PLAY terminal outputs a low level, the voice recording and playback module 16 is triggered to play sound. When the I / O port connected to the fast forward terminal FWD outputs a low level, the playback pointer of the voice recording and playback module 16 points to the next recording segment.

[0037] The relay module 21 consists of four relays. The relays are powered by VCC. The control terminals of the four relays are connected to the four I / O ports of the microcontroller 15, respectively, to control the connection of the four EL light-emitting boards 6 to the EL driver module 18 in different time periods, so as to light up and turn off the corresponding EL light-emitting boards 6. The EL driver module 18 uses a commercially available EL driver with a working voltage of 3V, and its power supply is a separate 3.2V lithium iron phosphate battery.

[0038] The pyroelectric sensor module 19 uses a pyroelectric infrared sensor, model SR602. Its output terminal is connected to one I / O port of the microcontroller 15. When human movement is detected, it outputs a high level.

[0039] The motor drive module 20 is model L9110. Its two control terminals are connected to the two I / O ports of the microcontroller 15 respectively, and are used to control the forward and reverse rotation of the geared motor 3. The output terminals of the two slot-type optocouplers are connected to the two external interrupt input ports of the microcontroller 15 respectively. In this embodiment, the controller is powered by two lithium iron phosphate batteries, and the positive and negative terminals are connected to the Vin pin of the Arduino Nano and ground respectively.

[0040] The working process of this embodiment is as follows:

[0041] I. Main Components and Their Functions

[0042] Arduino Nano Module: Includes a microcontroller and main control unit.

[0043] Motor drive module: amplifies current and drives the motor.

[0044] Audio amplifier module: amplifies the audio signal from the voice recording and playback module to drive the speaker.

[0045] Pyroelectric sensor: detects moving human bodies.

[0046] Outer slot type optocoupler: determines the zero position of the light box.

[0047] Inner slot type optocoupler: determines the position of each light-emitting surface of the light box.

[0048] EL driver module: Provides high-voltage power to the EL light-emitting panel.

[0049] Audio recording and playback module: Records and plays narration.

[0050] Relay module: Switches the power supply to the EL LED panel.

[0051] Four EL light-emitting panels of different colors: provide backlighting for the lightbox.

[0052] II. Work Process

[0053] First, record the narration for the four screens in sequence in the recording and playback module;

[0054] After power-on, the microcontroller 15 in the Arduino Nano module detects the first slotted optocoupler 8 on the outside to determine if the light box 5 is in the zero position. If it is not in the zero position, it sends a reverse rotation signal to the motor drive module 20 to make the motor rotate in the opposite direction until the first slotted optocoupler 8 on the outside is blocked by the first light-shielding plate 10 on the outside (outputting a low level), and stops rotating. Then, it detects human movement through the pyroelectric sensor module 19. If human movement is detected, the current position (first EL light-emitting board 6) is lit up (by controlling the relay module 21), and the voice recording and playback module 16 is triggered to play the first recording (narration). If the pyroelectric sensor module 19 does not detect human movement, it continues to detect.

[0055] The microcontroller 15 continues to determine if there is human movement. If so, the microcontroller 15 sends a signal to the motor drive module 20 again to drive the motor to rotate and detect the second slot-type optocoupler 9 on the inner side until the second slot-type optocoupler 9 on the inner side is blocked by the light-shielding sheet on the inner side (outputting a low level; there are 4 light-shielding sheets on the inner side, distributed at 90 degrees). At this time, the current position (second EL light-emitting board) 6 is lit up (by controlling the relay module 21), and the voice recording and playback module 16 is triggered to play the second recording (narration). Then, the microcontroller 15 continues to determine if there is human movement... and so on, until the 4th screen is completed. If the microcontroller 15 detects human movement again, the microcontroller 15 sends a reverse signal to the motor drive module 20 to return the light box 5 to zero and start from the beginning, preparing for a new round of rotation, display, and playback.

[0056] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
