[0002] Traditional refrigerator sliding rails only offer basic sliding functionality and cannot achieve intelligent control. Current technologies, such as a single remote control or simple sensors, control door opening and closing, resulting in limited interaction methods, high response delays, and a lack of real-time status feedback. Furthermore, built-in refrigerators have stringent requirements for the dimensional accuracy and noise control of the sliding rails, making it difficult for existing technologies to simultaneously meet aesthetic and functional needs. Regarding sliding rail travel control, current technologies often employ single Hall effect sensors, which are prone to position detection deviations due to signal interference or mechanical wear, leading to over-opening or incomplete closing of the door, impacting user experience and energy efficiency.

[0013] Furthermore, the power module is powered by a rechargeable battery.

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

[0015] 1. This utility model significantly improves the ease of use and intelligence of drawers by integrating multimodal interaction and precise control modules.

[0022] 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.

[0023] like Figure 1 As shown, this utility model proposes a multifunctional drawer control system, including a core control module 1, a power supply module 2, a tapping sensor 3, a Hall sensor 4, an infrared sensor 5, a wireless communication module 6, a voice acquisition and broadcasting module 7, a motor drive module 8, and a touch screen 9. The core control module 1 is electrically connected to the power supply module 2, the tapping sensor 3, the Hall sensor 4, the infrared sensor 5, the wireless communication module 6, the voice acquisition and broadcasting module 7, the motor drive module 8, and the touch screen 9. The motor drive module 8 is electrically connected to the drawer motor 10.

[0024] The core control module 1 is a control circuit based on a single-chip microcomputer, model STM8S003F3P6TR. This microcomputer, as the core of the system, is responsible for receiving and processing signals transmitted from various modules such as the tap sensor and Hall sensor. It controls the drawer motor's movement through the drive motor module, and coordinates the touchscreen operation response, voice acquisition and broadcasting functions. It is the central hub ensuring the stable and efficient operation of the entire drawer control system.

[0025] like Figure 3 As shown, power module 2 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. The AP1501-33 chip has efficient voltage regulation and conversion capabilities, which can accurately convert the 24V DC output from the rechargeable lithium battery to 5V to meet the power supply requirements of some modules; the ME6211C33M5G-N chip further converts 5V to 3.3V to meet the low-voltage power supply requirements of core control modules, etc. The dual conversion circuit ensures stable power supply to each module and avoids voltage fluctuations affecting system operation.

[0026] like Figure 4 As shown, the tap sensor 3 is a surface-mount vibration switch, model HX1210-C06. This sensor is mounted on the drawer door and features a surface-mount design, making it compact and easy to install. It accurately detects user tapping motions on the door, converting the vibration signal into an electrical signal that is transmitted to the core control module. Combined with preset tapping logic, it controls the drawer opening and closing without requiring manual contact with the touchscreen, providing a convenient contactless operation method for users.

[0027] The wireless communication module 6 is a 4G / 5G wireless communication module. This module supports high-speed and stable 4G / 5G network connections, enabling real-time data interaction between the drawer control system and remote terminals. Users can remotely monitor the drawer's open / closed status, receive sensor feedback information, and remotely send control commands to manipulate the drawer's movements via mobile phones and other devices.

[0028] like Figure 5 As shown, the voice acquisition and broadcasting module 7 is a chip with model number HLK-V20-SUIT. This chip integrates voice acquisition and broadcasting functions, and can acquire user voice commands and transmit them to the core control module for recognition and processing, execute corresponding drawer control operations, and broadcast information such as drawer opening and closing status and fault prompts in real time, realizing voice interactive control.

[0029] Motor drive module 8 is a three-phase gate drive chip, such as EG3033.

[0030] like Figure 2 The diagram shows a Hall effect sensor circuit. Hall effect sensor 4 is installed at the start and end points of the drawer's slide rail. When the door opens or closes, the Hall effect sensor detects a change in the magnetic field strength, thereby monitoring the door's position in real time and triggering an automatic closing or manual mode switch.

[0031] A touchscreen 9, a tap sensor 3, and an infrared sensor 5 are installed on the drawer door. The door can be opened and closed by operating the touchscreen, by tapping the door (detected by the tap sensor), or by waving a hand in front of the infrared sensor.

[0032] Power module 2 is powered by a rechargeable battery, such as a lithium battery. The lithium battery outputs a 24V DC voltage, which is converted into 5V DC and 3.3V DC by power module 2 to power various circuit modules.

[0033] The working principle of this multi-functional drawer control system is as follows:

[0034] The power module provides a stable power supply for the entire system, using a rechargeable lithium battery as the power source and outputting 24V DC. A DC circuit based on the AP1501-3.3 chip converts the 24V voltage to 5V to meet the power requirements of modules such as the infrared sensor and touchscreen. Then, a circuit based on the ME6211C33M5G-N chip further converts the 5V to 3.3V to meet the low-voltage power requirements of the core control module and wireless communication module. This dual voltage regulation and conversion design effectively avoids voltage fluctuations from interfering with system operation, ensuring stable operation of all modules.

[0035] Users can issue control commands through various interactive methods: the touchscreen, tap sensor, and infrared sensor are all installed on the drawer door. Users can directly operate the touchscreen to input switch commands, which are transmitted to the core control module via electrical signals. Alternatively, users can tap the door, and the HX1210-C06 surface-mount vibration switch (tapping sensor) detects the vibration signal and converts it into an electrical signal, which is then transmitted to the core control module to trigger the corresponding action. Users can also wave their palm in front of the infrared sensor, which detects the human body signal and transmits it to the core control module for contactless switch control. In addition, the voice acquisition and broadcasting module (HLK-V20-SUIT chip) can collect user voice commands, transmit them to the core control module for recognition and processing, execute corresponding control operations, and simultaneously broadcast real-time information such as drawer open / close status and fault prompts, realizing voice interaction and status feedback.

[0036] After receiving instructions from various interactive modules, the core control module outputs control signals to the motor drive module. The motor drive module uses a three-phase gate driver chip (such as EG3033). Upon receiving signals from the core control module, it drives the drawer motor to operate precisely, enabling smooth opening and closing of the drawer. Hall effect sensors installed at the start and end positions of the drawer slide rails detect the drawer's running position in real time. When a change in magnetic field strength is detected, the position signal is fed back to the core control module. Based on the feedback signal, the core control module determines whether the drawer has reached its limit position and promptly issues a command to stop the motor, preventing over-opening or incomplete closing and ensuring stroke control accuracy.

[0037] The wireless communication module employs 4G / 5G wireless communication to enable real-time data interaction between the system and remote terminals. The core control module transmits information such as drawer operating status and sensor detection data to remote devices like user mobile phones via the wireless communication module, allowing users to remotely monitor the drawer status. Simultaneously, users can also send control commands via remote terminals, which are transmitted to the core control module through the wireless communication module, enabling remote control of the drawers. The entire system achieves multi-mode interaction, precise control, status feedback, and remote monitoring of the drawers.

[0038] In addition, this utility model adds a clutch to the slide rail and further adds a Hall effect device to the slide rail, which can realize the effect of pushing the door to close when the motor stops. The microcontroller receives the signal to assist in closing the door. Moreover, during the motor movement, the dual Hall detection makes the door opening and closing position more accurate, and the microcontroller can also respond more quickly when encountering obstacles.

[0039] 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.
