Technical Field

[0001] This utility model relates to the technical field of air conditioning training platforms, specifically a highly stable air conditioning system diagnostic training platform. Background Technology

[0002] With social development and economic progress, more and more people are using cars, leading to the rise of automotive engineering and other related majors. As a crucial piece of equipment in automobiles, automotive air conditioning plays a vital role in the comfort and quality of the vehicle. Therefore, testing the automotive air conditioning system is directly related to the overall quality of the car.

[0003] The existing Chinese utility model patent with publication number CN208903547U discloses an automatic air conditioning system training platform, including a chassis, a teaching panel, and an automotive air conditioning assembly. The automotive air conditioning assembly includes a compressor, condenser, evaporator, expansion valve, receiver-drier, and air conditioning controller connected according to the air conditioning system of a real vehicle. An electric fan is installed on the condenser, and a blower is installed on the evaporator. The teaching panel is fixed in front of the automotive air conditioning assembly and tilted upwards. The teaching panel displays a colored air conditioning system circuit diagram and an air conditioning control panel, which is connected to the air conditioning controller. It also includes a fault setting module connected to the automotive air conditioning assembly. This utility model features a colored air conditioning system circuit diagram, which, in conjunction with the various components of the air conditioning system assembly, allows students to more easily understand the circuitry of the air conditioning system and master it more firmly. Furthermore, the fault setting module allows students to set various faults, enabling them to understand the causes of these faults and how to resolve them.

[0004] Based on the aforementioned patent searches and the findings of existing equipment, the air conditioning system diagnostic training platform is a student simulation learning device. However, traditional air conditioning system diagnostic training platforms lack any protective structure at the top, leading to damage to components when the platform is bumped or knocked down after use. Furthermore, the absence of any protective structure at the top allows dust to enter the components, causing further damage. Additionally, the poor internal structural stability of the air conditioning system diagnostic training platform during use can result in student injuries due to malfunctions. All these issues affect the usability of the device. Utility Model Content

[0018] Compared with the prior art, the present invention provides a highly stable air conditioning system diagnostic training platform with the following advantages:

[0019] 1. This utility model, through the design of the overall device, features a frame with a base composed of standard steel and aluminum profiles and high-brightness anodized aluminum industrial profiles, encased in an ABS molded outer cover. A movable, freely rotating trolley is mounted at the bottom, complete with ergonomically designed handles. The frame is equipped with casters, a self-locking device, and is flexible, safe, reliable, durable, and convenient for teaching and training. This training platform utilizes the air conditioning system assembly of an E5 pure electric vehicle. The system mainly consists of an electric compressor, condenser, HVAC assembly, refrigeration piping, PTC, warm water pipes, air ducts, and an air conditioning controller, providing four functions: cooling, heating, defrosting / defogging, and ventilation. The system uses PTC water heating and a vapor compression refrigeration cycle for cooling, employing R410a refrigerant and POE refrigeration oil. The control method is button operation. The mode damper, cooling and heating mixing damper, and internal and external circulation damper of the automatic air conditioning unit are all controlled by DC motors.
