The 7-inch LCD screen and the PCB board are connected by a cable and fixed together on the PCB fixing bracket. A CAN communication module and a Bluetooth module are added to the PCB board to realize the customer's multimedia functions such as Bluetooth music, Bluetooth calls, charging information display, reversing interface information display and reversing trajectory line display. The instrument front shell and the instrument back shell The instrument glass cover is located on the outside of the front shell of the instrument and is fixed with sealant to protect the internal 7-inch LCD screen. Reinforcement ribs are arranged at the bottom of the rear shell of the instrument and are evenly distributed in a mesh to ensure the strength of the rear shell of the instrument. The instrument communication plug-in, buzzer, and microphone are all welded to the PCB board as one to meet the information prompts and voice input functions of the instrument and multimedia. The front mounting foot of the instrument, the rear left mounting foot of the instrument, and the rear right mounting foot of the instrument are integrated with the rear shell of the instrument and are distributed on the front and rear sides of the rear shell of the instrument. Holes are opened on the mounting feet and are equipped with instrument mounting springs. Three bolts are used to fix the front and back to ensure installation reliability and convenience.

[0006] The beneficial effects of the present invention are: it adopts the form of a full liquid crystal combination instrument, which can display the necessary information of new energy vehicles and integrate the basic information of multimedia at the same time; the overall structure is simple, the installation is reliable, the size is small, the layout of the whole vehicle is more concise and effective, and the production cost of parts is low and the installation is simple, which can effectively reduce the cost of parts and manufacturing costs of the whole vehicle.
