Multifunctional intelligent electric vehicle instrument

Abstract

The invention discloses a multifunctional intelligent electric vehicle instrument which comprises an instrument panel case and a formaldehyde detecting device, wherein an engine tachometer, a speedometer and an electricity meter are sequentially arranged from left to right inside the instrument panel case; the engine tachometer and the speedometer are separately and electrically connected to an engine of an electric vehicle; the electricity meter is electrically connected to an electricity detector inside the electric vehicle; a display screen and an alarm trigger switch are sequentially arranged from top to bottom inside the instrument panel case and between the engine tachometer and the speedometer; the formaldehyde detecting device comprises a formaldehyde detecting sensor, a data comparator and a feedback module; and the output end of the formaldehyde detecting sensor and the output end of an electric vehicle processor are separately and electrically connected to the input end of the data comparator. The multifunctional intelligent electric vehicle instrument of the invention effectively monitors the formaldehyde content value in the electric vehicle in real time by virtue of the design of the formaldehyde detecting device, so that measured value can be more accurate.

Description

technical field [0001] The invention relates to the technical field of electric vehicle instrument panels, in particular to a multifunctional intelligent electric vehicle instrument. Background technique [0002] An electric vehicle (BEV) refers to a vehicle that is powered by a vehicle-mounted power supply, drives the wheels with a motor, and meets the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional vehicles, its prospects are widely optimistic, but the current technology is not yet mature; pure electric vehicles, compared with fuel vehicles, the main difference (difference) lies in the four major components, drive motor, speed controller , power battery, car charger. Compared with gas stations, it consists of public ultra-fast charging stations. The quality difference of pure electric vehicles depends on these four components, and its value also depends on the quality of these four components. The use of...

Problems solved by technology

[0003] The dashboards of existing pure electric vehicles only display the speed, speed and power of the vehicle, and the functions are relatively limited; the dashboards of existing pure electric vehicles do not yet display the formaldehyde content inside the car body. When knowing the formaldehyde value in the car, it is necessary to provide other formaldehyde detection equipment to detect the formaldehyde content. It is not only cumbersome to operate, but also increases the cost of formaldehyde detection, and is not conducive to real-time detection of the formaldehyde value in the car. The use has limitations At the same time, there is no emergency alarm device on the instrument panel of the existing pure electric vehicle, and the owner needs to call the police through mobile phones and other equipment in case of emergency, which not only prolongs the alarm time, but also is not conducive to the operation of the owner. limited use
