Description

A miniature training device suitable for the teaching of automobile body electrical appliances

technical field

The invention belongs to the field of teaching appliances, and in particular relates to a miniature training device suitable for the teaching of automobile body electrical appliances.

Background technique

In the current field of auto repair vocational teaching, teachers generally divide the teaching process of "removing electrical faults of automobile body" into eight teaching steps as shown in Table 1:

Table 1 Teaching steps to eliminate electrical faults in automobile body

serial number step learning carrier 1 Observe the normal operation of the car body circuit system Vehicle 2 Observing the working phenomenon of the faulty circuit system of the automobile body Vehicle 3 Analyze the working principle of the automobile body circuit system car circuit diagram 4 Predicting the location of faults in automotive body circuit systems car circuit diagram 5 Detect technical parameters of automobile body circuit system Vehicle 6 Judging the fault location of the automobile body circuit system Vehicle 7 Repair car body circuit system failure Vehicle 8 The test run confirms that the fault of the car body circuit system has been eliminated Vehicle

According to the above-mentioned teaching steps, it can be found that the whole vehicle is the core learning carrier for carrying out troubleshooting training teaching.

However, there will be the following problems with the vehicle as a whole as an on-site teaching entity:

(1) Only very few students can observe and learn the teacher's practical training operation at the same time, that is, due to the partial non-essential body (they do not need to be equipped with car body electrical appliances) and the small space in the car, only 2-3 students can At the same time, observe and learn the teacher's operation process, which seriously reduces the efficiency of teaching;

(2) It is difficult for teachers to observe and guide students’ practical training operations, that is, due to the small and crowded space in the car, and the hidden installation position of electrical components in the car body, teachers must use special positions or from special angles to observe and guide students in time. The process is very hard;

(3) The cost of the whole car is high, the utilization rate is low, and the hidden danger of teaching safety is great, that is, the whole car is equipped with a large number of systematic equipment (such as engine system and chassis system) that have nothing to do with the teaching of car body electrical appliances, and the cost is relatively high, but these The equipment not only cannot serve the teaching of automobile body electrical appliances, and has no utilization rate at all, but also often leads to component damage and unintentional work due to the touch of students, which increases the safety hazards and management costs of teaching;

(4) The transfer and parking requirements of the whole car are high, that is, the whole car, as a single device with a size of at least 4.6*1.7*1.5m, is relatively large in terms of volume, dead weight, and floor space. In the process, it puts forward higher requirements on lifting equipment, training room passage, training room door width, training room area and shape, which greatly limits the flexibility of teaching.
