detailed description

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the mobile terminal generally includes a housing 110, a printed circuit board (PCB) 120, a power supply unit (for example, a battery 130), a function card 140 (for example, a SIM card or an SD card or an NFC card, etc.), and the like. Various functional modules are integrated on the printed circuit board 120, and the battery 130 provides power to the various functional modules integrated by the printed circuit board 120. The battery 130 shown in Figure 1 is designed to be non-removable, in this case Next, the battery 130 is not detached and the function card 140 disposed inside the mobile terminal is taken out, so the function card 140 is usually disposed at the side of the mobile terminal to facilitate exiting from the mobile terminal. The function card 140 can be withdrawn from the mobile terminal in the action of an external force. The user can press the function card with a finger to cause the function card to exit from the mobile terminal. As an example, the function card 140 can be withdrawn from the mobile terminal by inserting a card ejecting mechanism or the like attached to the function card attached to the mobile terminal into a hole provided in the vicinity of the function card 140. In addition, a card holder for accommodating the function card 140 may be provided so that the user can press the card holder with a finger to eject the card tray together with the function card 140, or use the card ejecting mechanism to eject the card tray together with the function card 140.

The battery integrated design of the above mobile terminal can enhance the anti-theft function of the mobile terminal, and can make the mobile terminal look more beautiful, but this design may cause the mobile terminal to have insufficient system memory, improper operation, incompatible software and operating system, etc. In the event of a crash, the battery cannot be removed and reloaded to re-power it to solve the problem of the mobile terminal crashing.

In order to solve the above problem, a power switching mechanism is needed to quickly and effectively restart the mobile terminal when the mobile terminal crashes.

2 is a schematic diagram of an essential part of a mobile terminal including a power switching mechanism according to an embodiment of the present invention. Referring to FIG. 2, a mobile terminal according to an embodiment of the present invention includes a battery 210, a function module 230, and a power switching mechanism 220. The power switching mechanism 220 according to the present invention includes a switching unit 221. As shown in FIG. 2, the switch unit 221 is disposed on the power supply line of the battery 210 and the function module 230. The energization line can be turned on by turning on the switch unit 221 by the operation of the function card 222 to be installed and used, and the power-on line can be disconnected by the operation of withdrawing the function card 222 from the mobile terminal, wherein the function The card 222 may include a SIM card or an SD card or an NFC card or the like. Alternatively, the switch unit 221 may be a trigger or a commonly used flexible switch. For example, if the switch unit 221 is a trigger, when the function card 222 is inserted, the bottom edge (or any portion) of the function card 222 abuts the trigger switch unit 221, thereby turning on the power-on line, and when the function card 222 is exited, The switching unit 221 is triggered again, thereby disconnecting the energized line. Alternatively, when the switch unit 221 is a flexible switch, when the function card 222 is inserted, the bottom edge (or any part) of the function card 222 can abut against the switch unit 221, press the switch unit 221, and the switch unit 221 is turned on, thereby The energizing line is turned on, and when the function card 222 is withdrawn, so that the external force applied to the switching unit 221 is removed, the switching unit 221 can be automatically turned off, thereby disconnecting the energizing line. The switch unit 221 is switched by the function card 222 in FIG. 2, but this is merely an example, and the switch of the switch unit 221 can also be realized by using the card tray matched with the function card 222, and the principle is the same as the foregoing, Duplicate descriptions are omitted.
