Description

Automatic ejection device and method for SIM card of intelligent communication device Technical Field

[0001] The present invention belongs to the technical field of intelligent communication equipment, and in particular relates to an automatic ejection device and an automatic ejection method for a SIM card of an intelligent communication equipment. Background Art

[0002] As smart communication devices, especially smartphones, become increasingly closely connected with modern people's lives, they have even become an indispensable part of many people's daily lives. They are not only communication devices, but also many work tools, which store a large amount of important data. Therefore, protecting smart communication devices and the important data stored in them is becoming more and more important. The existing common technology is to use physical methods, using a SIM card eject needle to poke the card through the pinhole next to the SIM card tray to remove the card. This method is a simple physical method and most people can complete this operation. Most existing smartphones also have the function of remotely finding the phone through software. These various technologies for finding the phone require the premise that the smartphone maintains communication.

[0003] However, the current SIM card management method for smart devices has serious flaws. It cannot guarantee the safe management of the SIM card of a smart communication device after it is lost or stolen, and cannot ensure that the smart communication device can maintain communication after it is lost or stolen, making various technologies for retrieving smart communication devices meaningless, causing serious troubles for the retrieval of smart communication devices. At the same time, due to the existence of a pinhole, and this pinhole inevitably passes directly through the cavity of the smart device, once the smart device falls into water, water will enter most of the internal areas of the smart communication device through the pinhole, including but not limited to the circuit board, battery pack and other parts. This makes it possible for the smart device to fall into water and damage the smart communication device, especially the important data stored therein. Therefore, we need to propose an automatic ejection device and automatic ejection method for the SIM card of a smart communication device to solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic ejection device and method for a SIM card of an intelligent communication device. The present invention can greatly improve the security of mobile phone SIM card management and enhance the waterproof performance of the mobile phone, thereby more effectively protecting the mobile phone and the important data stored therein, thereby solving the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A SIM card automatic ejection device for an intelligent communication device comprises a PCB board and a SIM card holder welded to the PCB board. A card tray is movably inserted into the SIM card holder, and a locking spring is provided inside the SIM card holder for locking the card tray. A push rod is slidably connected to one side of the SIM card holder, and one end of the push rod passes through a notch in the SIM card holder and extends to the outside of the SIM card holder. A card tray ejection mechanism for pushing the push rod is fixed to the PCB board.

[0007] The card tray ejection mechanism includes a stepper motor, a screw rod and a push plate. The push plate is slidably connected to the PCB board, and the push plate is threadedly connected to the screw rod. The screw rod is fixed to the PCB board through a bracket. The stepper motor is installed at one end of the screw rod, and one end of the push plate is in contact with one end of the push rod.

[0008] Preferably, the bracket includes two fixing plates, both of which are fixed in parallel on the PCB board, and both ends of the screw rod are rotatably connected to the two fixing plates respectively, and the base of the stepper motor is fixed on one side of one of the fixing plates.

[0009] Preferably, a protrusion is fixed to the lower end of the push plate, and a sliding groove for the protrusion to slide is provided on the PCB board.

[0010] Preferably, the card tray includes a support plate and a fixing block, the fixing block is fixed to one end of the support plate, the other end of the support plate is symmetrically provided with locking notches on two opposite sides, and the upper surface of the support plate is provided with a placement slot for placing the SIM card.

[0011] Preferably, a clearance hole is provided inside the placement slot for the SIM card metal PAD to contact the contact PIN in the SIM card holder, and a sealing ring is sleeved on one end of the support plate close to the fixing block.

[0012] Preferably, when the support plate is inserted into the SIM card holder, the raised portion of the locking spring is located inside the locking notch to lock the SIM card; when the push rod is pushed into the SIM card holder by the push plate, the raised portion of the locking spring moves out of the locking notch, causing the SIM card to automatically pop out of the SIM card holder.

[0013] Preferably, a plurality of solder pins are equidistantly arranged at the lower end of the SIM card holder, and a soldering PAD for soldering the plurality of solder pins is provided on the PCB board.

[0014] Based on the above-described device for automatically ejecting a SIM card of an intelligent communication device, the present invention further provides a method for automatically ejecting a SIM card of an intelligent communication device, comprising the following steps:

[0015] S1. When the smart communication device is turned on and unlocked, find the corresponding SIM card management software. When using the software for the first time, you will be prompted to preset the authentication information. After the preset information is saved, select the corresponding card removal operation;

[0016] S2. The SIM card management software pops up an identity authentication window, prompting you to complete the identity authentication.

[0017] S3. Enter the authentication information. After successful authentication, proceed to the next step.

[0018] S4. After the SIM card management software passes the identity verification, the mobile phone power supply is connected to the circuit of the stepper motor. The stepper motor drives the push plate to provide a thrust to the ejector rod to move into the SIM card holder, causing the ejector rod to move into the SIM card holder and the stepper motor to immediately return to its initial state.

[0021] Preferably, in step S3, when the identity authentication information is entered incorrectly, you are prompted to re-enter it. If you enter the information incorrectly three times in a row, the phone will enter the lock screen state; after the smart communication device is locked, enter the unlocking information. If the unlocking is successful, you will continue to enter the SIM card management software and jump to the password retrieval prompt and password reset interface. If the unlocking cannot be successful, please contact the seller of this smart communication device for after-sales support.

[0022] The automatic ejection device and method for ejecting a SIM card of an intelligent communication device proposed in the present invention have the following advantages over the prior art:

[0023] 1. The present invention drives the screw to rotate by a stepping motor, so that the screw drives the push plate to move. When the push plate moves, it provides a force for the push rod to move toward the inside of the SIM card holder. The push rod moves toward the inside of the SIM card holder, and the card tray is automatically ejected from the SIM card holder through the push of the push rod. The stepping motor drives the push rod to move toward the inside of the SIM card holder and immediately returns to its initial state, thereby completely replacing the action of manually poking with a needle to eject the card tray so that the user can complete the subsequent SIM card removal and replacement operation. There is no need to open a pinhole on the device, which can greatly improve the security of mobile phone SIM card management and improve the waterproof performance of the mobile phone, thereby more effectively protecting the mobile phone and the important data stored therein.

[0024] 2. This invention uses more intelligent SIM card management to achieve safer SIM card usage, preventing unidentified individuals from maliciously replacing the SIM card of a smart communication device. This more effectively ensures the rationality of SIM card communication. In particular, after a smart communication device is lost or stolen, it can effectively protect the network status of the smart communication device and provide network security for more timely recovery of the lost or stolen smart communication device. Through intelligent management, the owner only needs to pass identity verification to manage the SIM card, eliminating the need to worry about finding a card removal pin, making card retrieval easier and more convenient.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] The present invention provides an automatic SIM card ejection device for an intelligent communication device, as shown in Figures 1-4. The device comprises a PCB board 1 and a SIM card holder 2 welded to the PCB board 1. A card tray is movably inserted into the interior of the SIM card holder 2, and a locking spring is provided inside the SIM card holder 2 for locking the card tray. A push rod 7 is slidably connected to the interior of one side of the SIM card holder 2, and one end of the push rod 7 passes through a notch in the SIM card holder 2 and extends to the outside of the SIM card holder 2. A card tray ejection mechanism for pushing the push rod 7 is fixed to the PCB board 1.

[0032] When installing the card tray, insert the card tray into the notch of the SIM card holder 2. When the protrusion of the locking spring is located inside the locking notch 10, the card tray is fixed to the SIM card holder 2, so as to fix the SIM card inside the SIM card holder 2.

[0033] The card tray ejection mechanism includes a stepper motor 3, a screw rod 4 and a push plate 6. The push plate 6 is slidably connected to the PCB board 1, and the push plate 6 is threadedly connected to the screw rod 4. The screw rod 4 is fixed to the PCB board 1 through a bracket. The stepper motor 3 is installed at one end of the screw rod 4, and one end of the push plate 6 is in contact with one end of the push rod 7.

[0034] When the card tray is pulled out, the stepper motor 3 drives the screw rod 4 to rotate, so that the screw rod 4 drives the push plate 6 to move. When moving, the push plate 6 provides a force for the ejector rod 7 to move toward the inside of the SIM card holder 2. The ejector rod 7 moves toward the inside of the SIM card holder 2 and the card tray is automatically ejected from the SIM card holder 2 by the push of the ejector rod 7. The stepper motor 3 drives the ejector rod 7 to move toward the inside of the SIM card holder 2 and immediately returns to its initial state, thereby completely replacing the action of manually poking with a needle, so that the card tray is ejected so that the user can complete the subsequent SIM card removal and replacement operation. There is no need to open a pinhole on the device, which can greatly improve the security of mobile phone SIM card management and improve the waterproof performance of the mobile phone, thereby more effectively protecting the mobile phone and the important data stored therein.

[0035] The bracket includes two fixing plates 5, both of which are fixed in parallel on the PCB board 1, and the two ends of the screw rod 4 are rotatably connected to the two fixing plates 5 respectively. The base of the stepping motor 3 is fixed on one side of one of the fixing plates 5. The two fixing plates 5 are used to facilitate fixing the screw rod 4 to one side of the SIM card holder 2, so that one side of the push plate 6 contacts one end of the ejector rod 7, so that the push plate 6 applies a force to the ejector rod 7 to move toward the inside of the SIM card holder 2, thereby causing the ejector rod 7 to drive the internal locking spring to deform, so as to eject the card tray.

[0036] A protrusion 15 is fixed to the lower end of the push plate 6, and a slide groove 16 for the protrusion 15 to slide is provided on the PCB board 1. Through the sliding cooperation between the protrusion 15 and the slide groove 16, the push plate 6 can move horizontally on the PCB board 1 while the stepping motor 3 drives the screw rod 4 to rotate.

[0037] The card tray includes a support plate 8 and a fixing block 11. The fixing block 11 is fixed to one end of the support plate 8. The other end of the support plate 8 is symmetrically provided with locking notches 10 on both sides. The upper surface of the support plate 8 is provided with a placement slot 9 for placing the SIM card. The placement slot 9 is used to limit the installation of the SIM card. The locking notch 10 is used to lock the installed card tray to connect and fix the card tray to the SIM card holder 2.

[0038] The interior of the placement slot 9 is provided with a clearance hole 13 for the SIM card metal PAD to contact the contact PIN in the SIM card holder 2. The support plate 8 is sleeved with a sealing ring 12 on one end close to the fixed block 11. Through the setting of the sealing ring 12, when the card tray is inserted into the SIM card holder 2, the sealing between the card tray and the device socket can be improved, thereby improving the waterproof effect of the device.

[0039] When the support plate 8 is inserted into the SIM card holder 2, the raised portion of the locking spring is located inside the locking notch 10 to lock the SIM card. When the push rod 7 is pushed into the SIM card holder 2 by the push plate 6, the raised portion of the locking spring moves out of the locking notch 10, causing the SIM card to automatically pop out of the SIM card holder 2.

[0040] The lower end of the SIM card holder 2 is equidistantly provided with a plurality of solder pins, and the PCB board 1 is provided with a soldering pad 14 for soldering the plurality of solder pins. The soldering pad 14 facilitates soldering and fixing the SIM card holder 2 to the PCB board 1;

[0041] Based on the above-described device for automatically ejecting a SIM card of an intelligent communication device, the present invention further provides a method for automatically ejecting a SIM card of an intelligent communication device, comprising the following steps:

[0042] S1. When the smart communication device is powered on and unlocked, the corresponding SIM card management software is found. When using the software for the first time, it will prompt you to preset the identity verification information. After the preset information is saved, the corresponding card retrieval operation is selected; wherein, the identity verification information is set to one of a string of characters, a fingerprint, a graphic, and information that is consistent with the unlock verification information in the locked state of the mobile phone.

[0043] S2. The SIM card management software pops up an identity authentication window, prompting you to complete the identity authentication.

[0044] S3. Enter the authentication information. After successful authentication, proceed to the next step.

[0045] If you enter the authentication information incorrectly, you will be prompted to re-enter it. If you enter the incorrect information three times in a row, the phone will enter the lock screen state. After the smart communication device is locked, enter the unlock information. If the unlock is successful, you will continue to enter the SIM card management software and jump to the password retrieval prompt and password reset interface. If the unlock is unsuccessful, please contact the seller of this smart communication device for after-sales support.

[0046] S4. After the SIM card management software passes the identity verification, the mobile phone power supply is connected to the circuit of the stepper motor 3. The stepper motor 3 drives the push plate 6 to provide a thrust to the ejector 7 to move into the SIM card holder 2, causing the ejector 7 to move into the SIM card holder 2 and the stepper motor 3 to immediately return to its initial state. The stepper motor 3 is disconnected from the power circuit, thus completely replacing the manual needle-poking action, causing the card tray to pop out so that the user can complete the subsequent SIM card removal and replacement operation.

[0047] S5. After the SIM card replacement operation is completed normally, insert the SIM card tray into the SIM card holder 2 in the correct way and push it firmly into place.

[0048] In summary, using more intelligent SIM card management makes SIM usage safer, prevents unidentified persons from maliciously replacing the SIM cards of smart communication devices, and more effectively ensures the communication rationality of the SIM card. Especially after the smart communication device is lost or stolen, it can effectively protect the network status of the smart communication device and provide network security for more timely recovery of lost or stolen smart communication devices. Through intelligent management, the owner only needs to pass the identity verification to manage the SIM card, and no longer needs to worry about finding the card removal pin, making card removal and replacement easier and more convenient.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
