Abstract
The utility model relates to a multimedia switching box used for an automobile. Two PCBs which are arranged at an upper layer and a lower layer respectively are arranged in the switching box. One of the PCB is a power control panel which is provided with USB input ports, an SD-card input port, an AUX input port, an Earphone output port, a Mini USB output port and a power input port. The USB input ports and the SD-card input port are connected with the Mini USB output port through a USB concentrator. The AUX input port is directly connected with the Earphone output port. The power input port is connected with an external power supply and signal wires of the AUX input port and the Earphone output port. The other of the PCB is a video control board which is provided with an HDMI input port, an RCA input port and an LVDS output port. The HDMI input port and the RCA input port are connected with the LVDS output port respectively. Compared with the prior art, the multimedia switching box used for the automobile has the advantages of being reasonable in structure, convenient to use and stable in signal transmission and the like.
