Electric car instrument assembly

Abstract

The invention discloses an electric car instrument assembly. The electric car instrument assembly comprises a shell, a plurality of instruments, indicator lamps, an indicator lamp control unit, an instrument control unit and a power module which is used for power supply, wherein the instruments and the indicator lamps are arranged on the upper surface of the shell, and the indicator lamp control unit, the instrument control unit and the power module are arranged in the shell. The shell comprises an upper shell body and a lower shell body, buckles and buckle grooves are formed in the upper shell body and the lower shell body, the buckles correspond to the buckle grooves, and the upper shell body and the lower shell body are combined and installed together through the cooperation of the buckles and the buckle grooves. The instrument control unit comprises an MCU module, a CAN bus module connected with the input end of the MCU module, a speedometer stepping motor connected with the output end of the MCU module, an LED current display and an LED electric quantity display. The electric car instrument assembly has the advantages of being easy to assemble, clear and accurate in information displaying, good in communication real-time performance, low in cost and the like.

Description

technical field [0001] The invention relates to an electric vehicle instrument assembly, which belongs to the technical field of vehicle instruments. Background technique [0002] An electric vehicle refers to a vehicle powered by a vehicle-mounted power supply, driven by a motor to drive the wheels, and conforming to the requirements of road traffic and safety regulations. [0003] The traditional electric vehicle instrument assembly mainly has the following defects: [0004] 1. At present, electric vehicle instrumentation communication generally adopts the wiring method of one line for one lamp and one line for one meter, which leads to troublesome and prone to problems in wiring harness wiring; [0005] 2. The traditional instrument shell is fixed by screws, which will increase the quality hazards on the circuit board and reduce the equipment efficiency; [0006] 3. Ammeters and electricity meters generally use pointers to indicate, and the error is large. [0007] In ...
