Description

Technical Field

[0001] This utility model relates to the field of intelligent storage device technology, and in particular to a multifunctional smartphone storage cabinet with a modular expansion structure. Background Technology

[0002] With the widespread adoption of information management in various settings, schools, examination centers, and enterprises are increasingly demanding centralized mobile phone management. Currently, most common mobile phone storage devices are passive lockers, offering only basic physical storage without real-time monitoring of phone status or data reporting capabilities. Some improved models attempt to incorporate technologies such as button detection, photoelectric sensing, or RFID identification to achieve status awareness; however, these solutions generally suffer from high costs, complex structures, or limited accuracy, making them unsuitable for large-scale, high-reliability centralized management applications.

[0003] In recent years, some smartphone cabinet products have adopted infrared beam detection technology to detect the presence of smartphones and use wireless communication modules to interact with the backend server. However, this technology still has many limitations in centralized smartphone management applications: First, the accuracy of smartphone presence recognition is insufficient, and mainstream detection methods such as infrared beam detection are easily affected by external environmental interference, affecting the accuracy of status judgment. Second, the system communication mechanism is imperfect; some devices lack the ability to automatically reconnect after power failure, resulting in the inability to restore connection and data synchronization in a timely manner after the server restarts. In addition, existing equipment has weak capabilities in multi-cabinet collaborative expansion, making it difficult to support unified deployment and management in large-scale scenarios. In terms of structural design, the internal component layout is chaotic, lacking standardized wiring and modular design, further increasing maintenance difficulty. Finally, the communication link stability is insufficient, and there is a lack of effective retransmission and repair mechanisms after data loss, so the overall system reliability still needs to be improved.

[0004] Therefore, there is an urgent need to provide a multifunctional smartphone storage cabinet with a modular expansion structure to solve the above problems. Utility Model Content

[0005] The technical problem this invention aims to solve is that the system is not yet perfect in terms of multi-device collaborative work and automatic reconnection mechanism after communication interruption. In actual use, it still faces risks such as false alarms, missed alarms, and even data loss.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: It includes a cabinet, multiple mobile phone slots on the cabinet, and a circuit system inside the cabinet. A base plate is fixedly installed at the lower end of the cabinet. A micro switch is installed at the bottom of each mobile phone slot. A switch bracket is fixedly installed on the micro switch. A micro switch mounting plate is installed inside the cabinet. The micro switch is fixedly installed on the micro switch mounting plate via a dedicated switch bracket. An electrical mounting plate is fixedly installed inside the cabinet. A signal acquisition and communication board is fixedly connected to the electrical mounting plate. An OLED display screen is also installed on the front panel of the cabinet.

[0007] With the above technical solution, a micro switch is provided at the bottom of each mobile phone slot. The status is recognized by the mobile phone's gravity. The micro switch is firmly installed on the micro switch mounting plate to ensure long-term stability.

[0008] The present invention is further configured such that a baffle is fixedly installed between the mobile phone slots.

[0009] Through the above technical solution, the mobile phone cabinet adopts a box-type structure with multiple mobile phone slots on the top, and the baffle can divide the internal capacity into spaces of different sizes.

[0010] The present invention is further configured such that: the circuit system includes a signal acquisition and communication board, a power supply module, a display module and a communication module; the signal acquisition and communication board uses an STM32F405 series microcontroller as the core processor; and the input terminal of the signal acquisition and communication board is interconnected with the signal output terminals of multiple microswitches through an optocoupler isolation circuit.

[0011] Through the above technical solution, the signal acquisition and communication board acquires the signal of the micro switch in an optically isolated manner and transmits it to the microcontroller for processing.

[0012] The present invention is further configured such that: the power supply module adopts a DC24V to 5V / 3.3V switching power supply circuit to power the signal acquisition and communication board and the display module; the communication module adopts an Ethernet communication circuit based on the RJ45 interface; and the display module is connected to the main control board through the I2C interface to display the device ID and the number of mobile phones currently stored in real time.

[0013] The present invention is further configured such that: the cabinet body adopts a three-layer modular layout, the upper layer of the cabinet body is a mobile phone slot module, the middle layer of the cabinet body is a circuit module, and the outer layer of the cabinet body is a shell module.

[0014] The present invention is further configured such that: a binding rod is fixedly installed inside the cabinet, a terminal block is provided on one side of the cabinet, a power supply is fixedly installed at the lower end of the electrical mounting plate, a network port and a power interface are respectively installed on one side of the cabinet, and ventilation holes are symmetrically opened on both sides of the cabinet.

[0015] Through the above technical solution, the cabinet interior adopts a three-layer modular layout and standardized wiring with binding rods, resulting in a clear structure that greatly facilitates later maintenance and repair.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention utilizes a mechanical microswitch as the detection element, directly triggered by the weight of the mobile phone, effectively avoiding the interference from ambient light that is common with infrared beam methods. It boasts high accuracy and low false alarm rate. The microswitch is securely and stably mounted using a dedicated bracket. Internally, it employs a three-layer modular layout and standardized wiring with binding rollers, resulting in a clear structure that greatly facilitates future maintenance and repair. When a status change is detected, the signal acquisition and communication board continuously sends multiple data packets at short intervals, ensuring reliable reception by the host computer. It also features a periodic "life message" reporting function, enabling the server to promptly perceive the device's online status and providing an effective disconnection detection and reconnection mechanism. Furthermore, the device ID can be set via an 8-bit DIP switch, supporting a network of up to 256 devices, easily meeting the needs of large-scale deployments. The device's OLED display screen provides real-time and intuitive display of the device ID and the number of mobile phones, facilitating on-site management. The cabinet is coated with anti-static paint and equipped with ventilation holes, balancing aesthetics, safety, and heat dissipation requirements. Attached Figure Description

[0027] Please see Figures 1-4 A multifunctional smartphone storage cabinet with a modular expansion structure includes a cabinet body 1, multiple phone slots on the cabinet body 1, and an internal circuit system. A base plate 2 is fixedly installed at the lower end of the cabinet body 1. A micro switch 6 is installed at the bottom of each phone slot, and a switch bracket 5 is fixedly installed on the micro switch 6. A micro switch mounting plate 4 is installed inside the cabinet body 1, and the micro switch 6 is fixedly installed on the micro switch mounting plate 4 via a dedicated switch bracket 5. An electrical mounting plate 3 is fixedly installed inside the cabinet body 1, and a signal acquisition and communication board 9 is fixedly connected to the electrical mounting plate 3. An OLED display screen 14 is also installed on the front panel of the cabinet body 1. Each phone slot has a micro switch 6 at the bottom, which is triggered by the weight of the phone to achieve status recognition. The micro switch 6 is firmly installed on the micro switch mounting plate 4 to ensure long-term stability.

[0028] A baffle 13 is fixedly installed between the mobile phone slots. The mobile phone cabinet adopts a box-type structure with multiple mobile phone slots on the top. The baffle can divide the internal capacity into spaces of different sizes.

[0029] The circuit system includes a signal acquisition and communication board 9, a power supply module, a display module, and a communication module. The signal acquisition and communication board 9 uses an STM32F405 series microcontroller as its core processor. The input terminal of the signal acquisition and communication board 9 is connected to the signal output terminals of multiple microswitches 6 through an optocoupler isolation circuit. The signal acquisition and communication board 9 acquires the signals of the microswitches 6 in an optocoupler isolation manner and transmits them to the microcontroller for processing.

[0030] The power supply module uses a DC24V to 5V / 3.3V switching power supply circuit to power the signal acquisition and communication board 9 and the display module. The communication module uses an Ethernet communication circuit based on the RJ45 interface. The display module is connected to the main control board through the I2C interface to display the device ID and the number of mobile phones currently stored in real time.

[0031] The cabinet 1 has a three-layer modular layout. The upper layer inside the cabinet 1 is a mobile phone slot module, the middle layer inside the cabinet 1 is a circuit module, and the outer layer inside the cabinet 1 is a shell module.

[0032] The cabinet 1 is equipped with a wire binding rod 7, a terminal block 8 is provided on one side of the cabinet 1, a power supply 12 is fixedly installed at the lower end of the electrical mounting plate 3, a network port 10 and a power interface 11 are respectively installed on one side of the cabinet 1, and ventilation holes are symmetrically opened on both sides of the cabinet 1. The cabinet 1 adopts a three-layer modular layout and standardized wiring with wire binding rods, with a clear structure, which greatly facilitates later maintenance and repair.

[0033] In use, when a mobile phone is placed in or removed from the phone slot, the state of the micro switch 6 changes. The signal acquisition and communication board 9, using an STM32F405 core processor, acquires 30 micro switch signals and communicates with the host computer via UDP protocol messages. It also sends three frames of status data to the host computer at 100ms intervals via Ethernet UDP protocol to ensure reliable communication. Simultaneously, the OLED display 14 updates its display content. The onboard 1.54-inch black-background white-text OLED display 14 can display the number and ID number of mobile phones in real time. Even without status changes, to prevent data loss due to abnormal restarts of the host computer, the phone cabinet sends a periodic information message every 60 seconds. If the server does not receive any messages for three consecutive minutes, it is determined that the phone cabinet is offline, and the OLED display 14 can display a warning message to remind staff to check the device connection status. The device ID set via the DIP switch allows multiple phone cabinets to work collaboratively on the same network without conflict.

[0034] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model.
