Description

Technical Field

[0001] This utility model relates to the field of storage cabinet technology, specifically to an intelligent classroom mobile phone centralized storage cabinet. Background Technology

[0002] With the widespread use of smartphones, mobile phones have become an indispensable part of students' daily lives. How students should use mobile phones reasonably on campus and how colleges can effectively manage mobile phones in the classroom are important issues of concern to both colleges and parents. While colleges are fully implementing paperless office practices, students still need to use their own mobile phones to complete tasks such as requesting leave, engaging in extracurricular learning, selecting courses online, evaluating courses, receiving learning assignments, and accessing relevant learning materials. Clearly, simply prohibiting students from using mobile phones is no longer feasible.

[0003] However, the improper use of mobile phones also has negative impacts on students' learning and lives. Especially during class, using mobile phones distracts students, making it difficult for them to focus on the lesson content and causing them to lose interest in learning. Furthermore, using mobile phones during class violates school rules and regulations, disrupting not only the teacher's instruction but also the learning of other students. Therefore, effective mobile phone management in the classroom is crucial for maintaining classroom order and improving teaching quality.

[0004] Current classroom phone management boxes only have a simple placement function. Students need teachers to supervise the process of handing in their phones, and teachers cannot easily count the names of students who have not handed in their phones. The functions are limited and the intelligence is low. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an intelligent classroom mobile phone centralized storage cabinet, which solves the problems of current mobile phone storage boxes being unable to statistically reflect students' mobile phone storage status and having limited functionality.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] An intelligent classroom mobile phone centralized storage cabinet includes a cabinet body, a camera installed on the upper front of the cabinet body, several independent compartments located below the camera on the front of the cabinet body, each compartment having a hinged door that locks to the compartment via an automatic lock, a groove at the bottom of the compartment containing a photoelectric sensor, a transparent plate connected to the top of the groove, a cable hole on the rear wall of the compartment for inserting a three-pronged charging cable, a touch display and a QR code scanner on one side of the front of the cabinet body, and a signal jammer on the inner side of the lower end of the cabinet body.

[0008] Preferably, the automatic lock includes a positioning block connected to one side wall of the cabinet compartment. The positioning block has a lock hole. A locking rod that mates with the lock hole is connected to the inside of the cabinet door. A first spring is connected inside the lock hole. A positioning hole is opened on the top surface of the locking rod. A sliding cavity is provided in the positioning hole. A positioning rod is slidably connected in the sliding cavity. A limit plate is connected to the periphery of the positioning rod in the sliding cavity. A second spring is connected to the bottom surface of the limit plate. The lower end of the second spring is connected to the bottom surface of the sliding cavity. A cover is connected to the upper part of the positioning block. A micro motor is provided inside the cover. A drive shaft is connected to the micro motor. A cam is connected to the drive shaft. The rotation of the cam can squeeze the positioning rod to move downward and insert it into the positioning hole.

[0009] In the above technical solution, when storing a mobile phone, the user enters the phone's storage information, such as class and name. If there is an empty cabinet, the motor works, driving the cam to rotate and causing the cam to move away from the positioning rod. Under the action of the second spring, the positioning rod moves upward, causing it to move away from the positioning hole. Meanwhile, under the action of the first spring, the locking rod pops outward, thereby opening the cabinet door.

[0010] Preferably, the upper part of the cabinet is equipped with a PLC controller, and the touch display, photoelectric sensor, camera, signal jammer, and micro motor are all electrically connected to the PLC controller.

[0011] The above technical solution uses a touch screen for manually inputting information such as class and name, a photoelectric sensor for detecting whether a mobile phone is stored in the cabinet, a camera for monitoring people in front of the cabinet to prevent theft, and a signal jammer for blocking mobile phone signals.

[0012] Preferably, the PLC controller is equipped with an information collection module and a 4G transmission module. The information collection module is used to collect information stored in the mobile phone, and the 4G transmission module is used to transmit the mobile phone status and the information stored in the mobile phone to the terminal.

[0013] In the above technical solution, the information collection module collects information stored on the mobile phone and transmits this information to the teacher's terminal. The 4G transmission module can transmit the mobile phone status to the learning platform, allowing students to check at any time whether their phones are still in the locker.

[0014] Preferably, the cabinet is also equipped with a temperature sensor, and a cooling fan is installed on the rear wall of the cabinet. The cooling fan is electrically connected to the PLC controller.

[0015] The above technical solution involves the phone generating high temperatures during charging. When the temperature sensor detects that the temperature is too high, the cooling fan will start and blow air into the compartment to dissipate heat.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The cabinets are used to store mobile phones, and the mobile phone signal jammer is used to block mobile phone signals to prevent mobile phones from interfering with the class. The photoelectric sensor is used to sense the storage status of mobile phones and whether there is a mobile phone in the cabinet. The touch display is connected to the cabinet signal and is used to manually input mobile phone storage information. It can also display the name of the corresponding student and whether the mobile phone is stored. If the mobile phone is not stored, the displayed status can be identified at a glance by the teacher, accurately count the list of students who have not handed in their mobile phones, and help the teacher intervene in management in a timely manner.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figure 1 and Figure 2An intelligent classroom mobile phone centralized storage cabinet includes a cabinet body 1. A PLC controller 13 is installed inside the upper part of the cabinet body 1. A camera 2 is installed on the upper front side of the cabinet body 1. Below the camera on the front side of the cabinet body 1, there are several independent compartments 3. Each compartment 3 is hinged with a door 4, which is locked to the compartment 3 by an automatic lock 5. A groove 6 is provided at the bottom of the compartment 3, and a photoelectric sensor 7 is installed in the groove 6. Each door is marked with a serial number, which corresponds one-to-one with the photoelectric sensor 7. The photoelectric sensor 7 is connected to the PLC controller 13 to transmit information about whether a mobile phone is in the corresponding compartment 3. A transparent plate 8 is connected to the top of the groove 6. A cable hole is provided on the rear wall of the compartment 3, through which a three-pronged charging cable 9 is inserted for charging different types of mobile phones. A touch display 10 and a QR code scanner 11 are provided on one side of the front of the cabinet body 1. A signal jammer 12 is provided on the inner side of the lower end of the cabinet body 1. The touch display 10, camera 2, and signal jammer 12 are all electrically connected to the PLC controller 13. Cabinet 3 is used to store mobile phones, and signal jammer 12 is used to block mobile phone signals to prevent interference with the class. Photoelectric sensor 7 is used to sense the storage status of mobile phones and whether a mobile phone is stored in the cabinet. The touch display 10 is connected to the cabinet signal and is used for manually inputting mobile phone storage information, and can also display the corresponding student's name and whether a mobile phone is stored. Mobile phone storage information can also be entered on the mobile phone by scanning a QR code.

[0027] like Figure 3 , Figure 4As shown, the automatic lock 5 includes a positioning block 501 connected to one side wall of the cabinet compartment. The positioning block 501 has a lock hole 502. The inner side of the cabinet door 4 is connected to a locking rod 503 that cooperates with the lock hole. A first spring 504 is connected inside the lock hole 502. A positioning hole 505 is opened on the top surface of the locking rod 503. A sliding cavity is provided inside the positioning hole 505. A positioning rod 506 is slidably connected inside the sliding cavity. A limit plate 507 is connected to the periphery of the positioning rod 506. A second spring 508 is connected to the bottom surface of the limit plate 507. The lower end of the second spring 508 is connected to the bottom surface of the sliding cavity. A cover is connected to the upper part of the positioning block 501. A micro motor 509 is provided inside the cover. The micro motor is electrically connected to the PLC controller 13. A drive shaft is connected to the micro motor 509. A cam 510 is connected to the drive shaft. The rotation of the cam 510 can squeeze the positioning rod 506 to move downward and insert it into the positioning hole 505. When cabinet door 4 is closed, locking rod 503 compresses first spring 504, causing first spring 504 to be in a contracted state. This activates micro motor 509, driving cam 510 to rotate. Cam 510 compresses positioning rod 506, causing positioning rod 506 to insert into positioning hole 505, thereby locking cabinet door 4 onto cabinet compartment 3. At this time, limiting plate 507 compresses second spring 508, causing second spring 508 to be in a contracted state. When cabinet door 4 needs to be opened, micro motor 509 rotates, driving cam 510 to rotate, causing the protrusion of cam 510 to move away from positioning rod 506. Positioning rod 506 bounces upward under the action of second spring 508, causing positioning rod 506 to pop out of positioning hole 505. At this time, under the action of first spring 504, locking rod 503 is pushed outward, thereby opening cabinet door.

[0028] The PLC controller 13 is equipped with an information collection module and a 4G transmission module. The information collection module is used to collect information stored in the mobile phones, and the 4G transmission module is used to transmit the mobile phone status and stored information to the terminal. Specifically, the information collection module collects the stored information from the mobile phones and transmits it to the teacher's terminal, allowing the teacher to remotely view the student mobile phone management status and the list of classes using the mobile phone storage rack, forming data that can be used as a basis for student performance evaluation.

[0029] Users can manually enter their phone's storage information, such as class and name, via a touchscreen display, or scan a QR code to enter information via their phone. If there is an available locker, the locker door will open automatically, allowing the phone to be placed inside. A photoelectric sensor will then transmit a signal to the PLC controller to detect the phone's status.

[0030] The touch display can also show the student's name and whether their phone is stored. If the phone is not stored, the displayed status allows the teacher to identify the student at a glance, accurately compile a list of students who have not handed in their phones, and help the teacher intervene in management in a timely manner.

[0031] Example 2

[0032] The difference between this embodiment and Embodiment 1 is that a temperature sensor is also provided inside the cabinet 3, and a cooling fan 14 is installed on the rear wall inside the cabinet 3. The cooling fan 14 is electrically connected to the PLC controller 13. When the mobile phone is charging, it will generate high temperature. When the temperature sensor detects that the temperature is too high, the cooling fan 14 will work to blow air into the cabinet to dissipate heat.
