Description

Technical Field

[0001] The invention belongs to the technical field of classroom management, and in particular relates to a mobile phone management device for students in a classroom. Background Art

[0002] With the development of science and technology, smart phones are becoming more and more popular, and are increasingly influencing and changing people's lifestyles and habits. On the subway, on the bus, at work, in meetings, even when walking or driving, you can see people staring at the screen of their mobile phone and sliding their fingers skillfully. Smart phones not only attract adults and make people unable to control themselves, but are also more attractive to students who do not have strong self-control as adults but have higher curiosity than adults. In class, there are always some students who consciously or unconsciously take out the mobile phone in their pockets and play with it attentively. This phenomenon has seriously affected normal teaching.

[0003] According to patent number CN202010198920.4 "Mobile Phone Classroom Manager for College Students", it consists of ten parts, including a double-layer rotating base, a column, an upper, middle and lower rotating disk combination, a sliding ball link combination, a support frame, a hexagonal prism cloth mobile phone bag combination, a dual-screen dual-core command and control device, a multi-section power data connector, a rubber rope and a mobile phone charging device. The circular rail groove and slide rail in the double-layer base complete the rotation between the base Ⅰ and Ⅱ, driving the rotation of the hexagonal prism cloth mobile phone bag combination, making it easier for students to find their respective positions and complete the unified management of mobile phones in the classroom. In order to avoid mobile phone ringtones and notification sounds disturbing the order of the classroom, students are often required to mute their mobile phones or adjust them to vibration mode before putting them in the bag; however, it is impossible to detect in time when the mobile phone receives a call, and it is difficult to judge the urgency when the call is not connected, which is easy to cause unnecessary interference to the teaching.

[0004] Patent No. CN202110485242.4 "A mobile phone management system for university classrooms" uses the socket, human infrared sensor and terminal to detect whether there are students at the desk, and wakes up the wireless signal detector, push switch and current detection module through the central processor. At this time, the student needs to put the mobile phone into the socket and plug the interface into the charging port of the mobile phone, so that the current detection module activates the electromagnetic block through the central processor, sucks the suction block, and the cover on the socket locks the mobile phone; because the socket is transparent, students can check whether the mobile phone has an emergency notification through the socket. If so, they can press the push switch, which is transmitted to the display screen through the central processor to prompt the teacher, so that the teacher can unlock the corresponding socket and let the student take out the mobile phone to operate. However, this method relies on the students' management of their own mobile phones. If the students use irrelevant information or calls to request the teacher to unlock the mobile phone, the teacher needs to go to the desk for re-inspection, which makes it difficult to quantitatively judge the urgency of the mobile phone letter, resulting in a waste of classroom time.

[0005] Therefore, designing a student classroom mobile phone management device that can isolate students from the influence of mobile phones, quantitatively judge the urgency of incoming calls, and promptly return the mobile phones to students to handle urgent matters has become a technical problem that needs to be solved urgently. Summary of the invention

[0006] In order to solve the above problems, the present invention provides a mobile phone management device for students in classroom.

[0007] The technical solution of the present invention is a student classroom mobile phone management device, including a management box, a controller and a plurality of storage compartments. The top surface of the management box is provided with a storage port, the side surface is provided with a machine access port, and the management box is also provided with a protective cushion at the bottom; the access port is provided with a mounting bracket; The storage bin is arranged in the management box, the top of the storage bin is connected to the mounting bracket and is provided with a take-in and put-out opening, the bottom is provided with a drop-out opening, and the outer side is provided with a driver; The drop opening is provided with an openable bottom cover, the bottom cover is made of a transparent material, a trigger cavity is provided inside the bottom cover, a gentle slope is provided at the bottom of the trigger cavity, a slider is placed on the gentle slope, and the slider is provided with a friction layer that fits the gentle slope; the friction coefficient between the friction layer and the gentle slope matches the gravity exerted on the slider on the gentle slope; The driver is provided with an infrared detection sensor and a stepper motor, and the stepper motor is provided with a driving shaft, which is connected to one side of the bottom cover and drives the bottom cover to rotate and open and close, and the positions of the infrared detection sensor and the driving shaft are matched with the bottom end of the gentle slope; The controller is installed on the side of the management box. The controller is electrically connected to the drive box for control and is provided with a switch button and a reset button.

[0008] After adopting the above method, by placing the management box next to the teacher's podium, before class, press the reset button on the controller, the controller sends a signal to start the stepper motor, the stepper motor drives the driving shaft to rotate at a constant speed, drives the bottom cover to flip downward to open the drop opening, and matches the position of the driving shaft with the bottom of the gentle slope. After the bottom cover flips downward, the bottom of the gentle slope that was originally at a low position becomes a high position, and the top of the gentle slope that was originally at a high position becomes a high position. The slider slides down to the original top position of the gentle slope, and then the driving shaft reverses to reset the bottom cover to close the drop opening. By setting the friction layer and The friction coefficient between the gentle slopes can match the gravity exerted on the slider on the gentle slope, so that the static friction exerted on the slider matches the influence of gravity along the direction of the gentle slope, ensuring that the slider will not slide during the resetting process of the bottom cover and will remain at the top of the gentle slope; when students enter the classroom, let the students adjust their mobile phones to vibration mode, and then gently put the mobile phones into each storage compartment from the access port and press them on the bottom cover, and then start teaching, avoiding mobile phone ringtones and prompt sounds disturbing the classroom order. At the same time, teachers manage mobile phones in a unified manner to prevent students from asking teachers for mobile phones with irrelevant calls.

[0009] By pressing the switch button on the controller, the infrared detection sensor is activated. When the mobile phone vibrates due to an incoming call, it is pressed on the bottom cover to transmit the vibration, causing the slider in the trigger cavity to vibrate. The contact area between the friction layer and the gentle slope is reduced, and the friction force on the slider is insufficient. Under the influence of gravity, it slowly slides to the bottom of the gentle slope. When the mobile phone stops vibrating, the slider returns to rest, and the time it takes for the slider to slide to the bottom of the gentle slope matches the total duration of the mobile phone's vibration, thereby quantitatively determining whether the mobile phone has received an emergency call. By matching the position of the infrared detection sensor with the bottom of the gentle slope, the infrared detection sensor can detect through the bottom cover of the transparent material to detect whether there is an obstacle at the bottom of the gentle slope in the trigger cavity. When the mobile phone In case of emergency, if the mobile phone receives calls continuously for a long time or receives multiple calls in a short time, the vibration causes the slider to slide to the bottom of the gentle slope. The infrared detection sensor detects that the slider is blocked and sends a signal to the controller. The controller starts the stepper motor and rotates the bottom cover to open and close the drop opening. During the process, the slider resets to the top of the gentle slope. After the drop opening is opened, the mobile phone naturally falls to the bottom of the management box and falls onto the protective cushion to prevent the phone from breaking. According to the sound made by the phone falling, the teacher can take the phone out of the pick-up port for the student to claim it, preventing the student from missing the emergency contact. By pressing the switch button again after the class, the infrared detection sensor can be turned off to save power consumption.

[0010] As a further improvement of the present invention, the driver is also provided with a positioning assembly, which includes a fixed magnet, a micro-cylinder and a separation push block; the fixed magnet is attached to the side of the bottom cover and corresponds to the top position of the gentle slope, the fixed magnet is connected to an elastic rod, the elastic rod is provided with a shaft sleeve sleeved on the outside of the driving shaft, an insertion gap is provided between the elastic rod and the bottom cover, and the side of the driving shaft is provided with a positioning clamping plate against the two ends of the shaft sleeve; the micro-cylinder is provided with a telescopic rod connected to the push block for vertical lifting, the bottom of the push block is provided with a wedge-shaped head with a narrow end facing downward, the wedge head is correspondingly arranged above the insertion gap, and the wedge head is provided with an extrusion slope on the side facing the elastic rod, and the top of the extrusion slope extends above the elastic rod; the slider is made of magnetic material and the magnetic pole matches the fixed magnet, and the slider is attached to the cavity wall of the trigger cavity and is magnetically fixed to the fixed magnet.

[0011] After adopting the above method, the fixed magnet is attached to the side of the bottom cover and corresponds to the top position of the gentle slope. The slider is made of magnetic material and is attached to the cavity wall of the trigger cavity and is magnetically fixed to the fixed magnet. This can avoid the vibration caused by putting the mobile phone into the storage bin or colliding with the management box, causing the slider to move down along the gentle slope, thereby maintaining the accuracy of quantitative judgment of emergency calls. After pressing the switch button, the controller sends a signal to control the micro cylinder, and the micro cylinder drives the telescopic rod to extend downward, pushing the separation push block down. The wedge-shaped head on the separation push block extends into the insertion interval, and the extrusion inclined surface contacts the elastic rod, which is extruded to bend in the direction away from the bottom cover. Since the positioning clamps on the driving shaft are against the two ends of the shaft sleeve, the shaft sleeve cannot move along the driving shaft. The bending of the elastic rod will drive the fixed magnet at the other end to form a gap away from the bottom cover, so that the slider loses the magnetic fixation of the fixed magnet and can slide down the gentle slope under the influence of the vibration of the mobile phone.

[0012] After the fixed magnet loses its magnetic attraction, the bent elastic rod exerts force to restore itself, and at the same time, under the action of gravity, it moves obliquely downward along the extrusion slope. During the process, the shaft sleeve rotates around the driving shaft until the elastic rod naturally hangs down. The shaft sleeve is sleeved on the outside of the driving shaft to ensure that the fixed magnet and the bottom cover rotate coaxially. When an emergency call occurs, the bottom cover rotates downward to align with the fixed magnet, and the slider falls back to the top of the gentle slope and is adsorbed by the fixed magnet. When the drop opening is closed, the fixed magnet flips upward with the bottom cover to further prevent the slider from sliding to the bottom of the gentle slope, and separates from the bottom cover again after contacting the wedge-shaped head, entering a state where the elastic rod naturally hangs down, and as the switch button is pressed at the end of the course, the micro-cylinder drives the telescopic rod to reset. When the reset button is pressed for operation, the bottom cover opens and closes once, so that the fixed magnet is adsorbed on the slider, and due to the reset of the telescopic rod, the elastic rod loses the extrusion of the wedge-shaped head, and the fixed magnet holds the magnetic attraction slider, restoring the function of keeping the slider in position when the mobile phone is placed in the storage compartment.

[0013] As a further improvement of the present invention, the mounting bracket is provided with a mounting hole corresponding to the storage bin, and the edge of the mounting hole is provided with an inward support plate; the top of the storage bin passes upward through the mounting hole, and a vibration gap is provided between the storage bin and the support plate, and the taking and placing port is provided with a connecting plate arranged above the support plate, and a vertical elastic support member is connected between the support plate and the connecting plate.

[0014] After adopting the above method, the support plate and the connecting plate are vertically connected through the elastic support parts, and a vibration gap is provided between the storage bin and the support plate. Relying on the elastic deformation of the elastic support parts, the storage bin is in a state that is easier to move. When the mobile phone vibrates, it can be better transmitted to the storage bin, ensuring that the slider and the gentle slope slide down relative to the vibration.

[0015] As a further improvement of the present invention, the top surface of the management box is provided with an openable and closable box cover, the box cover and the management box are provided with matching electronic lock components, the controller is electrically connected to the electronic lock component, and the controller is provided with a timer and a display for displaying timing.

[0016] After adopting the above method, by closing the box cover after class, the box cover and the electronic lock assembly on the management box are locked, and the timer on the controller is operated to set the next opening time of the electronic lock assembly to prevent students from taking mobile phones from the management box when the teacher is not paying attention.

[0017] As a further improvement of the present invention, the mounting bracket is provided with a plurality of marking grooves corresponding to the storage bins, and the marking grooves are provided with marking numbers arranged in sequence; the controller is provided with a buzzer and an indicator light for displaying the marking numbers.

[0018] After adopting the above method, a marking groove corresponding to the storage bin is set on the mounting bracket, and a marking number is set in the marking groove, so that when the student puts the mobile phone into the storage bin, the student can remember the corresponding marking number, and at the same time, the marking number can correspond one by one to the stepper motor on the storage bin. When the stepper motor is started to open and close the drop mouth and the mobile phone falls onto the protective cushion, the controller displays the marking number corresponding to the started stepper motor on the indicator light, thereby helping the teacher to return the mobile phone to the student accurately without the student identifying the characteristics of the mobile phone; by starting the buzzer to send a prompt sound while the indicator light displays the marking number, it is avoided that teachers and students fail to notice the sound of the mobile phone falling, causing the students to miss emergency contacts.

DETAILED DESCRIPTION

[0026] like Figure 1-Figure 6 The mobile phone management device for students in the classroom shown in the figure comprises a management box 1, a controller 2 and a plurality of storage compartments 3. The top surface of the management box 1 is provided with a storage port, and the side surface is provided with a machine access port 4. The management box 1 is also provided with a protective cushion 5 at the bottom; the access port 7 is provided with a mounting bracket 6; The storage bin 3 is arranged in the management box 1, the top of the storage bin 3 is connected to the mounting bracket 6 and is provided with a take-in and put-out port 7, the bottom is provided with a drop-out port 8, and the outer side is provided with a driver; The drop opening 8 is provided with an openable bottom cover 9, the bottom cover 9 is made of a transparent material, a trigger chamber 10 is provided inside the bottom cover 9, a gentle slope 11 is provided at the bottom of the trigger chamber 10, a slider 12 is placed on the gentle slope 11, and the slider 12 is provided with a friction layer that fits the gentle slope 11; the friction coefficient between the friction layer and the gentle slope 11 matches the gravity exerted on the slider 12 on the gentle slope 11; The driver is provided with an infrared detection sensor 13 and a stepper motor 14. The stepper motor 14 is provided with a driving shaft 15. The driving shaft 15 is connected to one side of the bottom cover 9 and drives the bottom cover 9 to rotate and open. The positions of the infrared detection sensor 13 and the driving shaft 15 are matched with the bottom end of the gentle slope 11. The controller 2 is installed on the side of the management box 1. The controller 2 is electrically connected to the drive box for control and is provided with a switch button and a reset button.

[0027] By placing the management box 1 next to the teacher's podium, before class, pressing the reset button on the controller 2, the controller 2 sends a signal to start the stepper motor 14, the stepper motor 14 drives the driving shaft 15 to rotate at a constant speed, driving the bottom cover 9 to flip downward to open the drop opening 8, and by matching the position of the driving shaft 15 with the bottom end of the gentle slope 11, after the bottom cover 9 flips downward, the bottom end of the gentle slope 11 that was originally at a low position becomes a high position, and the top of the gentle slope 11 that was originally at a high position becomes a high position, the slider 12 slides down to the original top position of the gentle slope 11, and then the driving shaft 15 is reversed to reset the bottom cover 9 to close the drop opening 8, and by setting a friction layer The friction coefficient between the slider 12 and the gentle slope 11 can match the gravity exerted on the slider 12 on the gentle slope 11, so that the static friction exerted on the slider 12 matches the gravity along the gentle slope 11, ensuring that the slider 12 does not slide during the resetting process of the bottom cover 9 and remains at the top of the gentle slope 11; when students enter the classroom, let the students adjust their mobile phones to vibration mode, then gently put the mobile phones into each storage compartment 3 from the access port 7 and press them on the bottom cover 9, and then start teaching, avoiding mobile phone ringtones and prompt sounds disturbing the classroom order. At the same time, the teachers manage the mobile phones in a unified manner to prevent students from asking the teachers for mobile phones with irrelevant calls.

[0028] By pressing the switch button on the controller 2, the infrared detection sensor 13 is started. When the mobile phone vibrates due to an incoming call, it is pressed on the bottom cover 9 to transmit the vibration, causing the slider 12 in the trigger cavity 10 to vibrate, and the contact area between the friction layer and the gentle slope 11 is reduced. The friction force on the slider 12 is insufficient, and it slowly slides to the bottom of the gentle slope 11 under the influence of gravity. When the mobile phone stops vibrating, the slider 12 returns to rest, and the time taken for the slider 12 to slide down to the bottom of the gentle slope 11 matches the total vibration duration of the mobile phone, thereby quantitatively determining whether the mobile phone has received an emergency call; by matching the position of the infrared detection sensor 13 with the bottom of the gentle slope 11, the infrared detection sensor 13 can detect through the bottom cover 9 of the transparent material whether there is an obstacle at the bottom of the gentle slope 11 in the trigger cavity 10, and when the hand When there is an emergency call, the mobile phone receives calls continuously for a long time or receives multiple calls in a short time. After the vibration causes the slider 12 to slide to the bottom of the gentle slope 11, the infrared detection sensor 13 detects that the slider 12 is blocked and sends a signal to the controller 2. The controller 2 starts the stepper motor 14 and rotates the bottom cover 9 to open and close the drop opening 8. During the process, the slider 12 is reset to the top of the gentle slope 11; after the drop opening 8 is opened, the mobile phone naturally falls to the bottom of the management box 1 and falls on the protective cushion 5 for buffering to prevent the mobile phone from breaking. The teacher can take the mobile phone out of the machine opening 4 according to the sound produced by the mobile phone falling and let the student claim it to prevent the student from missing the emergency call; by pressing the switch button again after the course, the infrared detection sensor 13 is turned off to save power consumption.

[0029] The driver is also provided with a positioning assembly, which includes a fixed magnet 16, a micro cylinder 17 and a separation push block 18; the fixed magnet 16 is attached to the side of the bottom cover 9 and corresponds to the top position of the gentle slope 11, and the fixed magnet 16 is connected to an elastic rod 19, and the elastic rod 19 is provided with a shaft sleeve 20 sleeved on the outside of the driving shaft 15, and an insertion gap is provided between the elastic rod 19 and the bottom cover 9, and the side of the driving shaft 15 is provided with a positioning clamping plate 21 against the two ends of the shaft sleeve 20 ; The micro cylinder 17 is provided with a telescopic rod 22 connected to the push block for vertical lifting and lowering, and the bottom of the push block is provided with a wedge-shaped head 23 with a narrow end facing downward, and the wedge-shaped head 23 is correspondingly arranged above the entry gap, and the wedge-shaped head 23 is provided with an extrusion slope 24 on the side facing the elastic rod 19, and the top of the extrusion slope 24 extends to the top of the elastic rod 19; the slider 12 is made of magnetic material and the magnetic pole matches the fixed magnet 16, and the slider 12 fits the cavity wall of the trigger cavity 10 and is magnetically fixed to the fixed magnet 16.

[0030] By fixing the magnet 16 on the side of the bottom cover 9 and corresponding to the top position of the gentle slope 11, the slider 12 is made of magnetic material and is attached to the cavity wall of the trigger cavity 10 and is fixed by magnetic attraction with the magnet 16, which can prevent the mobile phone from being placed in the storage compartment 3 or the vibration caused by the collision management box 1, causing the slider 12 to move down along the gentle slope 11, thereby maintaining the accuracy of quantitative judgment of emergency calls; after pressing the switch button, the controller 2 sends a signal to control the micro cylinder 17, and the micro cylinder 17 drives the telescopic rod 22 to extend downward, pushing the separation push rod 22 to move downward. The block 18 descends, the wedge-shaped head 23 on the separation push block 18 extends into the insertion gap, the extrusion slope 24 contacts the elastic rod 19, and the elastic rod 19 is extruded to bend in the direction away from the bottom cover 9. Since the positioning clamping plates 21 on the driving shaft 15 abut against the two ends of the shaft sleeve 20, the shaft sleeve 20 cannot move along the driving shaft 15. The bending of the elastic rod 19 will drive the fixed magnet 16 at the other end to form a gap away from the bottom cover 9, so that the slider 12 loses the magnetic fixation of the fixed magnet 16 and can slide down the gentle slope 11 under the influence of the vibration of the mobile phone.

[0031] After the fixed magnet 16 loses its magnetic attraction, the bent elastic rod 19 exerts force to restore, and at the same time, under the action of gravity, moves obliquely downward along the extrusion slope 24. During the process, the shaft sleeve 20 rotates around the driving shaft 15 until the elastic rod 19 naturally hangs down; the shaft sleeve 20 is sleeved on the outside of the driving shaft 15 to ensure that the fixed magnet 16 and the bottom cover 9 rotate coaxially. When an emergency call occurs, the bottom cover 9 rotates downward to align with the fixed magnet 16, and the slider 12 falls back to the top of the gentle slope 11 and is adsorbed by the fixed magnet 16; when the drop opening 8 is closed, the fixed magnet 16 flips upward together with the bottom cover 9. The slider 12 is further prevented from sliding toward the bottom of the gentle slope 11, and is separated from the bottom cover 9 again after contacting the wedge-shaped head 23, entering a state in which the elastic rod 19 naturally hangs down, and as the switch button is pressed at the end of the course, the micro cylinder 17 drives the telescopic rod 22 to reset; and when the reset button is pressed for operation, the bottom cover 9 is opened and closed once, so that the fixed magnet 16 is adsorbed on the slider 12, and because the telescopic rod 22 is reset, the elastic rod 19 loses the squeezing of the wedge-shaped head 23, and the fixed magnet 16 holds the magnetic slider 12, restoring the function of keeping the position of the slider 12 when the mobile phone is placed in the storage compartment 3.

[0032] The mounting bracket 6 is provided with a mounting hole 25 corresponding to the storage bin 3, and the edge of the mounting hole 25 is provided with an inward support plate 26; the top of the storage bin 3 passes through the mounting hole 25 upward, and a vibration gap is provided between the storage bin 3 and the support plate 26, and the access port 7 is provided with a connecting plate 27 arranged above the support plate 26, and a vertical elastic support member 28 is connected between the support plate 26 and the connecting plate 27.

[0033] The support plate 26 and the connecting plate 27 are vertically connected to each other through the elastic support member 28, and a vibration gap is provided between the storage bin 3 and the support plate 26. Relying on the elastic deformation of the elastic support member 28, the storage bin 3 is in a state that is easier to move. When the mobile phone vibrates, it can be better transmitted to the storage bin 3, ensuring that the slider 12 and the gentle slope 11 slide down relative to the vibration.

[0034] The top surface of the management box 1 is provided with an openable and closable box cover 29, and the box cover 29 and the management box 1 are provided with matching electronic lock components 30. The controller 2 is electrically connected to the electronic lock component 30, and the controller 2 is provided with a timer and a display for displaying timing.

[0035] By closing the box cover 29 after class, the box cover 29 and the electronic lock assembly 30 on the management box 1 are locked, and the timer on the controller 2 is operated to set the timing for the next opening of the electronic lock assembly 30, so as to prevent students from taking the mobile phone from the management box 1 when the teacher is not paying attention.

[0036] The mounting bracket 6 is provided with a plurality of marking grooves 31 corresponding to the storage bins 3 , and the marking grooves 31 are provided with marking numbers arranged in sequence; the controller 2 is provided with a buzzer and an indicator light for displaying the marking numbers.

[0037] By setting a marking groove 31 corresponding to the storage bin 3 on the mounting bracket 6, and setting a marking number in the marking groove 31, when the student puts the mobile phone into the storage bin 3, the corresponding marking number can be remembered, and at the same time, the marking number can correspond one by one to the stepper motor 14 on the storage bin 3. When the stepper motor 14 is started to open and close the drop opening 8 and the mobile phone falls onto the protective cushion 5, the controller 2 displays the marking number corresponding to the started stepper motor 14 on the indicator light, so as to help the teacher return the mobile phone to the student accurately without the student identifying the characteristics of the mobile phone; by starting the buzzer to send out a prompt sound while the indicator light displays the marking number, it is avoided that the teacher and the students fail to notice the sound of the mobile phone falling, causing the students to miss the emergency contact.
