Abstract

The invention relates to the technical field of electric vehicle instruments, and discloses an instrument circuit module with a GPRS communication interface. The instrument circuit module comprises ashell, a display screen, a circuit board, a processor, a liquid crystal display circuit, a power supply module, a backlight driving circuit, a speed sensor receiving end, a distance sensor receiving end and an electric quantity recording meter; the display screen is fixedly embedded on the upper surface of the shell, the circuit board is arranged inside the shell, the circuit board is horizontallyarranged, protection mechanisms are arranged on the left side and the right side of the circuit board, the processor, the liquid crystal display circuit, the power supply module, the backlight driving circuit, the speed sensor receiving end, the distance sensor receiving end and the electric quantity recording meter are all fixedly arranged on the upper surface of the circuit board, a through hole is formed in the right side wall of the shell, and the GPRS communication interface is fixedly arranged in the through hole. According to the instrument circuit module with the GPRS communication interface, the vehicle condition of an electric vehicle can be quickly and accurately known by a rider, and the using safety of the electric vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicle instruments, in particular to an instrument circuit module with a GPRS communication interface. Background technique [0002] Electric vehicles, including electric scooters and electric bicycles, refer to mechatronic personal vehicles that use batteries as auxiliary energy on the basis of ordinary vehicles and are equipped with motors, controllers, batteries and other components. [0003] The wheels of electric vehicles are driven by electric motors, and the power supply of electric motors comes from batteries. Many states in the driving of electric bicycles are not perceived by users, such as the driving speed of electric bicycles, current mileage, total mileage, battery charging and discharging current, battery remaining power, etc., and these are the information that users are very concerned about. Users need to understand the information of electric vehicles more comprehensively and ...
