Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle teaching, and in particular to a new energy vehicle teaching theory and practice testing platform. Background Art

[0002] With the continuous development of technology, new energy vehicles have been widely used in countries around the world with their advantages of high efficiency, environmental protection, and low carbon. At present, new energy vehicles have occupied 30% to 60% of the automobile market. In addition, with the support of the state's subsidies for the purchase of new energy vehicles, it has also greatly promoted the rapid development of new energy vehicles. However, new energy vehicles are emerging things after all. There are problems such as immature automobile manufacturing technology, low electricity and battery technology, and backward fault diagnosis and detection equipment for new energy vehicles. Therefore, the probability of failure of new energy vehicles is relatively high. Whether it is drive or energy, any problem will have a great impact on the stability and safety of vehicle operation, thereby posing a threat to the personal safety of the owner. Therefore, on-time vehicle inspection is an indispensable link, which can not only detect problems in time, but also prevent them before they happen. However, with the innovation of new energy technology, the inspection of new energy vehicles also tests the ability of inspection personnel. The professional and technical personnel of new energy vehicles lag behind, and various vocational colleges have successively opened automobile professional courses. Therefore, it is necessary to set up new energy vehicle teaching aids to assist in improving the quality and ability of inspection personnel.

[0003] At present, the production of new energy vehicle teaching aids in China is in the initial development stage. The finished teaching aids sold on the market have a single function and cannot meet the needs of various practical training. Many new energy teaching aids only take out one of the subsystems on the car body to make teaching aid training benches, which have limitations in the practical training process and can only realize the demonstration teaching of a certain function. The practical training projects that can be carried out are single and limited in function. They cannot meet the students' various practical training needs at the same time. In addition, the production cost of the teaching aid bench that realizes a single function demonstration is too high, and the investment in consumables is too large. It is only ornamental and lacks practicality. When students use teaching aids for practical training, they cannot master the integrity and comprehensiveness of professional skills training well, and are largely separated from the real situation of actual car repair, resulting in the inability of the technology they have learned to be truly used in production.

[0004] After searching, the Chinese patent with application number "201922268873.1" discloses a new energy vehicle teaching theory and practice integrated platform device, including a base, a display teaching device and a supporting device, a telescopic rod is provided between the base and the supporting device, the base and the supporting device are connected by the telescopic rod, and an axial hole is provided in the vertical direction of the center position of the base, and the display teaching device is rotatably connected with the base through the axial hole. The utility model adopts a supporting device and a display teaching device. When in use, the corresponding vehicle can be placed on the supporting device for practical operation. At the same time, the display teaching device can display the theoretical knowledge of the vehicle, combining practice and theory for simultaneous teaching, which greatly improves the teaching effect; the use of the telescopic rod and the rotating shaft can enable the platform device to perform practical operations on vehicles of different models. At the same time, the coordinated use of the first support rod, the second support rod and the third support rod can make the use of the display screen more flexible.

[0005] However, the above-mentioned new energy vehicle teaching theory-practice integrated platform device cannot effectively combine the content to be explained on new energy vehicles with the video explanation, and cannot highlight the components to be explained, resulting in the problem of great learning difficulty, poor understanding and low teaching quality for students during the explanation process.
