Description

Technical Field

[0001] The utility model relates to the technical field of air tightness detection for heavy truck inspection workshops, in particular to a whole vehicle air tightness detection device. Background Art

[0002] At present, heavy trucks must test the brake and non-brake air pressure before leaving the factory. In order to meet the requirements, improve the detection efficiency and accuracy, and ensure the quality of the whole vehicle, the manufacturer analyzed the whole vehicle air tightness detection method in the inspection workshop and found the following problems:

[0003] ① Currently, there is no air tightness testing equipment in the heavy truck inspection workshop. The air tightness test is completed by applying soap solution using the vehicle's own power source to supply air. This consumes fuel and produces gas slowly. It takes an average of about 30 minutes to complete the air tightness test of a heavy truck.

[0004] ② The vehicle's central console cannot detect and display the specific value of the brake system air pressure drop, which does not meet the specified requirements;

[0005] ③ Manually applying soap solution is time-consuming and laborious, and the test results are inaccurate and the quality cannot be guaranteed. Utility Model Content

[0006] The purpose of the utility model is to overcome the defects of the prior art and provide a vehicle air tightness testing device that can avoid the testing workshop using the vehicle's own power source to supply air and apply soap solution to test the air tightness of the vehicle.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] The vehicle air tightness detection device disclosed in the utility model comprises:

[0009] A control box, and a back plate fixedly connected to one side of the control box;

[0010] The top of the control box has a work surface, and an emergency stop button, a detection button, an air source switch, and a power switch are installed on the work surface away from the back panel, and an alarm is installed in the middle of the work surface;

[0011] The back plate is fixedly connected with a solenoid valve and a connecting pipeline;

[0012] The input end of the solenoid valve is connected to the connecting pipeline, the output end of the solenoid valve is connected to the vehicle air circuit, the connecting pipeline is also connected with a filter and a transmitter in sequence, and the connecting pipeline is connected to the gas supply station away from the solenoid valve end.

[0013] Furthermore, the control box is in the form of a box structure, with legs at the bottom and a door panel at one side.

[0014] Furthermore, the back plate structure extends vertically upward.

[0015] In the above technical solution, the vehicle air tightness detection equipment provided by the utility model is compared with the prior art:

[0016] The vehicle air tightness testing equipment, first of all, does not need to use the vehicle power source to supply air for air tightness testing, so that the workshop can centrally supply air, reduce fuel consumption, and be more energy-saving and environmentally friendly;

[0017] Secondly, there is no need to manually apply soap liquid, automatic detection is achieved, and the pressure value is accurate and visible, meeting regulatory requirements;

[0018] In addition, the inspection time is reduced from 30 minutes per unit to 6 minutes per unit, improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
