Description

Technical Field

[0001] This utility model relates to the field of smart home equipment technology, specifically to a smart door opening and closing electrical control system for a wine cabinet hinge. Background Technology

[0002] As specialized storage equipment for wines, wine cabinets require a balance between convenience and safety in their door opening and closing operations. They must prevent damage to bottles from excessive force when manually closing the door, while also preventing the door from being partially closed and affecting the internal temperature and humidity environment. Most existing wine cabinets use a purely manual door opening and closing design. While some smart wine cabinets offer electric door opening and closing, they have significant drawbacks: First, door position detection relies solely on a magnetic door sensor, which has low accuracy and cannot detect a half-open door, easily leading to a compromised storage environment due to an incompletely closed door. Second, they lack auxiliary closing functions, requiring users to manually close the door completely, resulting in poor operational convenience. Third, triggering methods are limited, often only supporting touchscreens or single-language voice control, making it difficult to adapt to different user habits. Fourth, the integration of anti-pinch functions is low, failing to meet the dual protection needs of fragile wine bottles inside the cabinet and the user's hands. Therefore, there is an urgent need for a wine cabinet door opening and closing electronic control system with high-precision position detection, auxiliary closing, multiple triggering methods, and reliable protection. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an intelligent opening and closing electrical control system for wine cabinet hinges, which, combined with the characteristics of wine storage scenarios, solves the shortcomings of existing technologies through dual position detection, multiple triggering methods and functional integration.

[0004] To solve the above-mentioned technical problems, the embodiments of this utility model provide the following technical solution: an intelligent hinged door control system for a wine cabinet, comprising a microprocessor, a hand gesture sensing unit, a touch screen unit, a voice interaction unit, a remote communication unit, a power module, a pressure sensor, a door magnetic sensor, a brushless motor drive module, and a brushless motor. The microprocessor is electrically connected to the hand gesture sensing unit, the touch screen unit, the voice interaction unit, the remote communication unit, the power module, the pressure sensor, the door magnetic sensor, and the brushless motor drive module. The brushless motor drive module and the brushless motor are electrically connected. The brushless motor is mechanically connected to the hinge mechanism of the wine cabinet.

[0005] Furthermore, the microprocessor uses a single-chip microcontroller of model STM32F103C8T6.

[0006] Furthermore, the hand gesture sensing unit uses the HY18037 chip.

[0007] Furthermore, the touchscreen unit adopts an anti-fingerprint capacitive touch panel.

[0008] Furthermore, the voice interaction unit uses a voice module of model HLK-V20-SUIT.

[0009] Furthermore, the remote communication unit adopts an ESP8266 Wi-Fi module.

[0010] Furthermore, the power module includes a 24V to 5V DC circuit based on the AP1501-3.3 chip, and a 5V to 3.3V DC circuit based on the ME6211C33M5G-N chip.

[0011] Furthermore, the pressure sensor is selected as a flexible thin-film pressure sensor.

[0012] Furthermore, the door magnetic sensor is a reed switch door magnetic sensor, installed at the upper right corner where the cabinet and the door meet.

[0013] Furthermore, the brushless motor drive module includes a MOS driver chip of model SA6188 and a MOSFET chip of model AGM312M2, and the output terminal of the SA6188 chip is electrically connected to the AGM312M2 chip.

[0014] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0015] This invention combines a pressure sensor with a door magnetic sensor to accurately identify the fully open, half-open, and fully closed states of the door, solving the problem of insufficient accuracy of traditional single sensors. The pressure sensor can detect whether the door is half-open, and in this state, it controls a brushless motor to slowly close the door at a low speed, preventing the door from affecting the temperature and humidity of the wine cabinet. It integrates multiple triggering methods to adapt to different user habits, and uses a Hall effect circuit integrated into the motor to achieve anti-pinch protection. Attached Figure Description

[0021] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figure 1 As shown, this utility model proposes an intelligent hinged door control system for a wine cabinet, including a microprocessor 1, a hand gesture sensing unit 2, a touch screen unit 3, a voice interaction unit 4, a remote communication unit 5, a power module 6, a pressure sensor 7, a door magnetic sensor 8, a brushless motor drive module 9, and a brushless motor 10. The microprocessor 1 is electrically connected to the hand gesture sensing unit 2, the touch screen unit 3, the voice interaction unit 4, the remote communication unit 5, the power module 6, the pressure sensor 7, the door magnetic sensor 8, and the brushless motor drive module 9. The brushless motor drive module 9 and the brushless motor 10 are electrically connected, and the brushless motor 10 is mechanically connected to the hinge mechanism of the wine cabinet.

[0023] like Figure 2 As shown, microprocessor 1 uses the STM32F103C8T6 microcontroller chip. The STM32F103C8T6 chip is selected as the core controller. This chip features high performance and low power consumption, and has built-in interfaces such as ADC, UART, and SPI. It can simultaneously connect to multiple trigger modules and detection modules to achieve rapid signal processing and instruction output, ensuring stable operation of the system in the low-power operating environment of the wine cabinet.

[0024] The hand gesture sensing unit 2 uses the HY18037 chip. The infrared sensor is installed on the top or front of the wine cabinet in an unobstructed area. When the user waves their hand within 10-20cm in front of the sensor, the HY18037 chip filters and amplifies the collected motion signal and outputs a digital signal to the main control module to trigger the door to open or close, thus avoiding fingerprint residue caused by hand contact with the surface of the wine cabinet.

[0025] Touchscreen unit 3 uses an anti-fingerprint capacitive touch panel. It is located in a concealed position on the side of the wine cabinet. Commands are input via touch-sensitive "open door", "close door", and "hover" buttons. The signals are converted by the touch chip and transmitted to the main control module. The operation is intuitive and does not affect the appearance of the wine cabinet.

[0026] like Figure 5 As shown, the voice interaction unit 4 uses a voice module of model HLK-V20-SUIT. This module integrates a high-performance speech recognition and synthesis chip, supporting contactless control by users through specific Chinese commands (such as "open the wine cabinet" or "close the cabinet door"). Simultaneously, the module can also provide voice feedback through a speaker to confirm the command execution status.

[0027] The remote communication unit 5 uses an ESP8266 Wi-Fi module, which is connected to the main control module via a UART interface. Users can wirelessly send door opening and closing commands via mobile phone and view the door's opening and closing status (fully open / half open / fully closed) in real time. When the door is not fully closed, an alarm is pushed to remind users to ensure a stable wine storage environment.

[0028] like Figure 4 As shown, the power module 6 includes a 24V to 5V DC circuit based on the AP1501-3.3 chip and a 5V to 3.3V DC circuit based on the ME6211C33M5G-N chip.

[0029] Pressure sensor 7 is a flexible thin-film pressure sensor. Three sensors are evenly distributed along the edge where the door and cabinet meet, corresponding to the left, center, and right positions of the door, respectively. When the door is closed, the pressure sensor contacts the cabinet and generates a pressure signal. The main control module collects the magnitude and distribution of the pressure value to accurately determine the degree of door closure. When the pressure value is <5N, it is determined to be in a half-open state, triggering auxiliary door closing; when the pressure value is ≥10N and the door magnetic sensor detects a fully closed signal, it is determined to be fully closed, and the motor stops running.

[0030] The door magnetic sensor 8 uses a reed switch door magnet, which is installed at the upper right corner where the cabinet and the door meet. When the door is fully closed, the magnet approaches the reed switch to close it, outputting a low level; when the door is fully open, it outputs a high level. It cross-verifies with the pressure sensor data to avoid misjudgment of position due to the failure of a single sensor.

[0031] like Figure 3 As shown, the brushless motor drive module 9 includes an SA6188 MOS driver chip and an AGM312M2 MOSFET chip. The output of the SA6188 chip is electrically connected to the AGM312M2 chip. The PWM control signal output by the microprocessor is first sent to the SA6188 MOS driver chip, which converts the low-voltage logic signal into a high-current gate signal that can quickly drive the MOSFET. The output of the SA6188 is directly connected to the gate of the AGM312M2 MOSFET. By adjusting the gate voltage and timing, the MOSFET is controlled to turn on and off, thereby regulating the magnitude and direction of the current flowing through the brushless motor windings.

[0032] The brushless motor 10 is composed of a hinge mechanism. The brushless motor 10 is mechanically connected to the hinge through a reduction gear set. The motor drives the hinge to open and close the door by rotating forward and backward. The motor adopts a low-noise design (operating noise ≤35dB) to meet the quiet use requirements of wine cabinets. It also has an adjustable speed function to meet the different speed requirements of normal door opening and closing (150-200rpm) and auxiliary door closing (50-80rpm).

[0033] The working principle of this utility model is as follows:

[0034] The main control chip is soldered to the main control board and fixed in the reserved space at the back of the wine cabinet. The brushless motor is mounted inside the left side of the cabinet via a bracket; the motor output shaft meshes with the hinge mechanism through a reduction gear set, and the hinge is fixed to the door. A pressure sensor is attached to the right edge of the door and connected to the main control board via a wire. Door magnetic sensors are installed at the upper right corner of the cabinet, corresponding to the door position. The HY18037 hand gesture sensor, touchscreen panel, microphone, and speaker are installed at preset positions on the top and sides of the wine cabinet; the ESP8266 Wi-Fi module is soldered to the main control board.

[0035] System operation process:

[0036] 1. Trigger Operation: Users can send door opening and closing commands via hand gesture, touch screen, voice, or ESP8266 Wi-Fi module. After receiving the command, the main control module outputs a PWM signal to control the brushless motor to drive the door to open and close.

[0037] 2. Position detection: The pressure sensor and the door magnetic sensor provide real-time feedback of position data, and the main control module determines the door status. When the pressure sensor detects that the door is in a half-open state (opening angle < 30°) and has not been fully closed for 5 seconds, the brushless motor is controlled to drive the door to close slowly at a low speed until the pressure sensor detects the rated pressure and the door magnetic sensor outputs a fully closed signal, so as to avoid the door not closing and affecting the temperature and humidity of the wine cabinet.

[0038] 3. Anti-pinch protection: During the operation of the door, the Hall circuit integrated in the motor collects the change signal of the motor rotor magnetic field in real time. When the door encounters an obstacle (such as pinching a hand or contacting a wine bottle), the motor load increases, the Hall signal frequency changes abruptly, and the main control module outputs a reverse command to control the motor to rotate in the opposite direction for 3-5cm and then stop until the obstacle is removed, protecting the user's hand and the wine bottle.

[0039] 4. Hovering and Switching: When the user initiates the door opening and closing action through any triggering method, and then triggers the same command again (such as waving the hand again), the main control module controls the brushless motor to maintain the current output torque based on the position data of the pressure sensor and the door magnetic sensor, so that the door stays at any opening and closing angle (30°-90°), making it convenient to pick up and put down wine bottles.

[0040] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
