fig. 2 is a schematic structural view of a partial cross section of the present invention.
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 conveniently taking out a SIM card, as shown in fig. 1-2, which includes an apparatus main body 1 and an MCU2 disposed in the apparatus main body 1, wherein the apparatus main body 1 is provided with a cavity 3, an opening of the cavity 3 is hinged with a card cover 4, a card cavity 5 is disposed in the cavity 3, and the card cavity 5 is used for placing the SIM card; a Hall switch 6 in communication connection with the MCU2 is arranged on one side of the cavity 3, and a magnetic component 41 is arranged in the card cover 4; a pressing and elastic device 7 is fixedly connected between the clamping cavity 5 and the cavity 3; the pressing and elastic device 7 is electrically connected with the MCU 2; and after the power is on, the pressing and ejecting device 7 is in a compressed state.
By adopting the structure, when a user needs to take out the SIM card, the user only needs to open the card cover, so that the magnetic component in the card cover is far away from the Hall switch, the Hall switch is triggered to generate a Hall effect, and a low level is output to the MCU, and after receiving the low level, the MCU outputs a high level with a preset time length of seconds (assumed to be 1.5 seconds) to the pressing and ejecting device, so that the pressing and ejecting device generates compression after being electrified and drives the card cavity to move downwards; and after the power is switched on for 1.5 seconds, the pressing and elastic device is powered off, the pressing and elastic device returns to the original shape, the pressing and elastic device rebounds to enable the card cavity to bounce upwards and recover the original height, and the SIM card in the card cavity continues to pop out due to inertia and is separated from the card cavity.
As shown in fig. 2, the pressing and elastic device 7 includes an iron sheet 71, a spring 72 and an electromagnet 73, the iron sheet 71 is fixedly connected with the bottom of the card cavity 5, one end of the spring 72 is connected with the bottom of the iron sheet 71, and the other end of the spring 73 is connected with the electromagnet 73; the electromagnet 73 is electrically connected with the MCU 2; the electromagnet 73 is arranged at the bottom of the cavity 3; after the power is switched on, the electromagnet 73 is attracted with the iron sheet 71.
In the structure, after the MCU and the electromagnet are electrified, the electromagnet generates a large magnetic attraction force to attract the iron sheet and simultaneously drive the clamping cavity to move downwards, and the spring is in a compressed state; after the electromagnet is powered off, the spring rebounds to drive the card cavity to restore to the original height, and the SIM card continues to move upwards due to inertia and is separated from the card cavity.
In this embodiment, as shown in fig. 1-2, the card cover 4 is made of a soft material.
In this embodiment, as shown in fig. 2, the SIM card can be placed in the card cavity 5.
When a user uses the device which is convenient for taking out the SIM card, firstly, the card cover is opened, the Hall switch is triggered to generate a Hall effect, and the MCU outputs a high level with a preset time duration of seconds (assumed to be 1.5 seconds) to the electromagnet, so that the electromagnet is electrified and then the magnetic attraction attracts the iron sheet and drives the card cavity to move downwards; after the power is switched on for 1.5 seconds, the electromagnet is automatically powered off, and the spring returns to the original shape; the spring rebounds to enable the card cavity to bounce upwards and restore the original height, and at the moment, the SIM card in the card cavity continuously pops up due to inertia and is separated from the card cavity.
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.
