摘要:
A wireless communication system and a wireless network accessing device are disclosed. The wireless communication system comprises an intelligent terminal and a wireless network accessing device. The intelligent terminal comprises a first card holder and a first interface. The first card holder is configured to receive a first SIM card, and the first interface is electrically connected to the first card holder. The wireless network accessing device comprises a second card holder, a second interface, a baseband chip and a switch module. The second card holder is configured to receive a second SIM card, the second interface is removably electrically connected to the first interface, and the switch module is electrically connected to the second card holder, the second interface and the baseband chip so that the baseband chip is selectively electrically connected to the first card holder or the second card holder for purpose of wireless network accessing through the first SIM card or the second SIM card. In this way, the baseband chip can be electrically connected to the first card holder or the second card holder selectively by means of the switch module, thereby making the wireless communication system compatible with two different cases in which an SIM card is disposed in the intelligent terminal and in which an SIM card is disposed in the wireless network accessing device.

An intelligent terminal that allows for replacement of a wireless communication device by a user is disclosed, which comprises an intelligent terminal body and the wireless communication device having a SIM card installed therein. A slot for accommodating the wireless communication device is disposed at a side of the intelligent terminal body, the wireless communication device is detachably inserted in the slot and connected to the intelligent terminal body via an interface, and the outer surface of the wireless communication device matches with the outer surface of the intelligent terminal body. Because the intelligent terminal adopts a wireless communication device whose outer surface matches with the outer surface of the body of the intelligent terminal the wireless network accessing function of the ultra-thin intelligent terminal (e.g., a tablet computer) is ensured even when no WiFi or 4G network resources are available. Meanwhile, comparing with the external wireless network accessing devices which has protruding part, this intelligent terminal can prevent the wireless network accessing device from being subjected to external impact and the consequent damage on the interface, so the availability and the reliability of the product in use are greatly improved. Moreover, the detachable wireless communication device also makes it convenient for the user to choose different kinds of wireless network accessing devices freely.

A fast charging terminal is provided, which includes a battery, a USB interface, a switch module, a supply voltage detecting unit, a central processor, and a charging management unit. After the USB interface is connected to an intelligent charger, the switch module is switched on when the supply voltage outputted by the USB interface is within a safe supply voltage range such that the charging management unit converts the supply voltage and the supply current. The charging management unit decreases the supply voltage and increases the supply current to charge the battery.

The present invention relates to a casing apparatus having the wireless communication function for a mobile terminal, comprising a casing apparatus body, and an antenna, a communication PCBA, and a battery supplying power to the communication PCBA that are arranged in the casing apparatus body; the communication PCBA is integrated with a digital communication module and a WIFI communication module, and the antenna and the battery are respectively connected to the communication PCBA. The casing apparatus according to the present invention transmits a WIFI signal from a tablet computer through the antenna to the WIFI communication module for processing, then transmits the processed signal to the digital communication module for modulation, and finally radiates the modulated signal through the antenna to access a wireless communication network. In this way, the WIFI signal from the tablet computer gets to access the network, thereby realizing the wireless access to the network even though there is no WIFI hotspot available.
