Drawings

Fig. 1 is a block diagram of a screen projecting device of a mobile phone.

In the figure: the system comprises 11-a mobile phone processor, 12-a mobile phone touch screen, 13-a mobile phone NFC module, 14-a mobile phone WIFI module, 21-a car processor, 22-a car display screen, 23-a car NFC module, 24-a car WIFI module and 25-sound equipment.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The embodiment of the utility model provides a screen device is thrown to on-vehicle cell-phone, as shown in figure 1, the device includes: the system comprises a mobile phone processor 11, a mobile phone touch screen 12, a mobile phone NFC module 13 and a mobile phone WIFI module 14 which are connected with the mobile phone processor 11, an in-vehicle processor 21, an in-vehicle display screen 22, an in-vehicle NFC module 23 and an in-vehicle WIFI module 24 which are connected with the in-vehicle processor 21; the mobile phone NFC module 13 is used for receiving the WIFI interconnection information coded by the mobile phone processor 11 and sending the WIFI interconnection information to the vehicle NFC module 23; the vehicle-mounted NFC module 23 is used for receiving the encoded WIFI interconnection information sent by the mobile phone NFC module 13, sending the encoded WIFI interconnection information to the vehicle-mounted processor 21, and decoding the WIFI interconnection information by the vehicle-mounted processor 21 to obtain WIFI interconnection information; the mobile phone WIFI module 14 and the car WIFI module 24 are used for transmitting screen projection data information.

In this embodiment, all hardware modules of the device are existing hardware modules respectively arranged inside the mobile phone and the car machine, and are respectively a mobile phone processor 11, a mobile phone touch screen 12, a mobile phone NFC module 13 and a mobile phone WIFI module 14 arranged inside the mobile phone, and a car machine processor 21, a car machine display screen 22, a car machine NFC module 23 and a car machine WIFI module 24 arranged inside the car machine. As shown in fig. 1. The device is used for carrying (projecting) the picture on the small mobile phone touch screen 12 to the large car machine display screen 22 so as to facilitate the operation and the watching of a user. The mobile phone WIFI module 14 and the car machine WIFI module 24 are used for data communication between a mobile phone and a car machine, namely, after the mobile phone is connected with the car machine, the mobile phone WIFI module 14 transmits screen-throwing data information to the car machine WIFI module 24, so that screen throwing from the mobile phone to the car machine is realized.
