I. Overview

This device can display the automotive electric power system, simulating the starting, low -speed driving, general driving, full -speed driving, decelerating driving, and parking state of the vehicle and the operating status of the motor. System work conditions.

It is suitable for the teaching needs of the pure electric vehicle power driving system of "New Energy Vehicle and Electronics Technology".

Second, structure composition

The device is launched by start switch, throttle pedal, gear switch, brake switch, digital speed meter, current indicator table, etc., and supplemented by the dynamic indicator of the system flow with the light emitting diode. Figures, control panels, mobile tables, use operation manuals, etc.

Third, functional characteristics

1. The device fully demonstrates the automotive electric power system, which can dynamically simulate the energy flow direction of the power flow in the start, low -speed driving, general driving, full -speed driving, deceleration and parking of parking and the running status of the motor.

2. Install a ignition switch, work condition switch, throttle pedal, gear switch, brake switch, digital speed meter, current indicator table, etc., supplemented by the dynamic instructions for system flowing in the light -emitting diode, and set it up. There is an analog motor to demonstrate the working state of the motor.

3. The appearance of the teaching plate panel is beautiful; the bottom part is welded with steel structure, the surface is treated with spraying process, a self -locking wheel device, and a desktop of about 30cm on the profile base, which is convenient for placing data and light detection instruments.

4. Machinery assembly and fitter assembly virtual simulation software: This software is developed based on Unity3D, which can choose 6 -level image quality. It has the design and virtual disassembly of the reducer and shaft structure, the design and simulation of common mechanical institutions, institutional resource libraries, institutional resource libraries. Typical mechanical institutions (virtual disassembly of gasoline engines), software is an overall software, which cannot be separate resources.

A. Turbine design and virtual disassembly interface can be selected from turbine sn--l pole cone gear reducer, second -level pilot gear reducer, conical cylindrical gear reducer, coaxial cylindrical gear reducer, cone gear reducer, first -class cylindrical, first -class cylindrical, Gear reducer.

The turbine sn--l tapered gear reducer: automatically play the assembly content after entering the software. Each step in the video has text description

Second -level unfolding cylindrical gear reducer: After entering the software, use the video to play content in the form of video. The video content should include: the name of the parts (scanning the QR code can see the part of the parts), the disassembly presentation (including disassembly, assembly), virtual disassembly Installation (including overall, low -speed shaft, mid -speed axis, high -speed shaft, box cover, box seat)
