Detailed Description
The present invention will be further described with reference to the accompanying drawings, and it should be noted that the present embodiment is based on the technical solution, and the detailed embodiments and the specific operation processes are provided, but the protection scope of the present invention is not limited to the present embodiment.
The embodiment provides a device for taking out a SIM card, as shown in fig. 1, the device includes a mobile device 1, and an MCU and a cavity 2 which are arranged in the mobile device 1, a card cavity 3 is arranged in the cavity 2, a card cover 4 is hinged above the card cavity 3, and a hall switch 5 and a booster circuit are also arranged in the cavity 2; a magnetic component is arranged in the card cover 4; the cavity 2 is also internally provided with a pressing and elastic device 6 and a lever mechanism 7, and the clamping cavity 3 and the pressing and elastic device 6 are respectively positioned above two ends of the lever mechanism 7; the pressing and elastic device 6 is sequentially connected with the booster circuit and the MCU in series; after the power is on, the pressing and elastic device 6 is in a compressed state, and after the power is off, the pressing and elastic device 6 can rebound to impact the lever mechanism 7; the SIM card is arranged in the card cavity 3, and the SIM card penetrates out of the bottom of the card cavity 3.
In the structure, after the card cover is opened, the magnetic component in the card cover is far away from the Hall switch to trigger the Hall switch to generate a Hall effect, the Hall switch generates weak magnetic induction and outputs a low level signal to the MCU, and the MCU receives the low level signal and then powers on the ramming device through the booster circuit; the power-on time of the missile pressing device by the MCU can be preset with a threshold value, and when the power-on time reaches the threshold value, the MCU automatically disconnects the power on of the missile pressing device; when the power is on, the pressing and ejecting device is in a compression state, and after the power is off, the pressing and ejecting device rebounds and instantaneously impacts one end of the lever mechanism, so that the lever mechanism is inclined; at the moment, the other end of the lever mechanism moves upwards and impacts the bottom of the card cavity, the SIM card extends out of the bottom of the card cavity, and the lever mechanism generates large pushing force and then instantaneously impacts the bottom of the SIM card in the card cavity to enable the SIM card to be automatically ejected.
In this embodiment, as shown in fig. 1, the pressing device 6 includes an electromagnet 61, a spring 62 and a striker 63, the electromagnet 61 is electrically connected to the MCU, one end of the spring 62 is fixedly connected to the electromagnet 61, and the other end is fixedly connected to the striker 63; the striking plate 63 is specifically an iron plate, and the electromagnet 61 is attracted to the striking plate 63 after being electrified.
In the structure, when the MCU energizes the electromagnet, the electromagnet generates a large magnetic attraction force to attract the striker to approach, so that the spring is compressed; after the electromagnet is powered off, the spring rebounds, so that the striker impacts the lever mechanism, and the lever mechanism is inclined after being impacted.
In this embodiment, as shown in fig. 1, the lever mechanism 7 includes a lever 71 and a support 72, and a middle portion of the lever 71 is hinged to the support 72; the card cavity 3 and the pressing and elastic device 6 are respectively positioned above two ends of the lever 71. In the structure, after the collision sheet collides one end of the lever, the other end of the lever generates larger thrust through the lever principle and instantaneously collides the bottom of the clamping cavity.
In this embodiment, as shown in fig. 1, an end of the lever 71 near the card cavity 3 is provided with a top block 711. The top block strikes the bottom of the card cavity when the lever is tilted.
The working principle of the SIM card taking-out device is as follows: after the card cover is opened, the magnetic component in the card cover enables the Hall switch to generate a Hall effect, the Hall switch generates weak magnetic induction, and a low level signal is output to the MCU; after the MCU receives the low level signal, the pressing device is electrified through the voltage boosting circuit; an electromagnet on the pressing and elastic device generates a large magnetic attraction force after being electrified to attract the striker to approach, and the spring is compressed when the striker approaches; the MCU controls the automatic power-off of the pressing device after the power-on time reaches a threshold value through presetting the threshold value of the power-on time; at the moment, the spring rebounds and drives the collision sheet to impact the lever instantly, and the other end of the lever generates a larger thrust force through the lever principle and impacts the bottom of the SIM card in the card cavity instantly to enable the SIM card to be ejected automatically.
Various corresponding changes and modifications can be made by those skilled in the art according to the above technical solutions and concepts, and all such changes and modifications should be included in the protection scope of the present invention.
