1. Product introduction

      The device is based on the physical object of the vehicle's external lighting system to fully display the structure and working process of the car's external lighting system.

It is suitable for the school's teaching needs for car lighting system theory and m--ntenance tr--ning.

2. Functional characteristics

1. Real and operating car external lighting system, fully display the composition of the car's external lighting system.

Manipulate various light switches to truly demonstrate the work process of the external lighting system of the car.

2. The teaching board panel adopts a ** aluminum -plastic plate with strike, pollution resistance, fire prevention, and moisture -proof, and spray primer p--nt on the surface by special crafts; school students can intuitively control the work and analyze the work of the automotive lighting system in accordance with the circuit diagram and physical objects. principle.

3. Detecting terminals are installed on the teaching panel, which can directly detect the electrical signals of the circuit components of the car's external lighting system on the panel, such as resistance, voltage, current, frequency signals, etc.

4. Demonstration panel parts use 1.5mm cold plate stamping and forming structure, beautiful appearance; the ch--n part is welded with steel structure, the surface is treated with spraying process, a self -locking wheel device, and a desktop on the base of the teaching plate. , Easy to place data, light detection instruments, etc.

5. The work of the teaching board adopts a normal 220V AC power supply, which is converted into a 12V DC power supply by transformed by the internal circuit. No battery is required to reduce the trouble of charging. The 12V DC power supply has a short circuit function.

6. Machinery assembly and fitter assembly virtual simulation software: This software is developed based on Unity3D. It can select 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,, institutional resource library, institutional resource bank, institutional resource library, institutional resource library, institutional resource library, institutional resource bank, institutional resource library, and institutional resource library. Typical mechanical institutions (virtual disassembly of gasoline engines), software is an overall software, which cannot be separate resources.
