[0002] In automotive air conditioning systems, the compressor is a core power component, and its performance directly impacts the vehicle's cooling and heating efficiency, energy consumption, and system reliability. With the increasing popularity of new energy vehicles, the demand for electric compressor testing has become increasingly demanding, while the maintenance demand for compressors in traditional fuel vehicles is also growing in the aftermarket.

[0003] In automobile manufacturing production lines and after-sales maintenance scenarios, the detection of compressor pressure and temperature is a key link to ensure the normal operation of the air-conditioning system. Traditional detection equipment usually uses a compressor tester to start the pressure and temperature detection of the compressor with one click. The compression tester consists of a power module, a pipeline module, a compressor tester body and an output module; and the refrigerant analysis function for the refrigerant filling amount and leakage status of the compressor is set independently. The operator is required to use an additional refrigerant filling, recovery and leak detection integrated machine for detection. During the detection process, manual start-up is required according to the steps in sequence. Manual operation is prone to detection errors due to missed steps or parameter setting deviations.

[0017] The following reference Figure 1 and Figure 2 The embodiments of the present invention will be described.

[0018] Example 1: The utility model proposes a one-button compressor detection system 4 that integrates the refrigerant processing process. The specific scheme of the utility model includes: a compressor detector 1, a display unit 2, a control module 3 and a detection system 4, wherein the compressor detector 1 is composed of a power module, a pipeline module, a compressor detector 1 main body and an output module, the power module is electrically connected to the external power socket to power the compressor detector 1 main body, one end of the pipeline module is connected to the compressor detector 1 main body for high and low voltage, and the other end is connected to the high and low voltage of the vehicle to be inspected, and the input end of the output module is connected to the compressor detector 1 main body through communication, and the output end is connected to the display unit 2 for communication, and the information interface of the compressor detector 1 main body is displayed on the display unit 2 through the output module, the input end of the control module 3 is connected to the output end of the display unit 2, wherein the display unit 2 contains a detection selection module, the detection selection module contains pressure detection instructions and temperature detection instructions, and the output end of the detection system 4 is connected to the output module for communication, and the detection system 4 contains a pressure test module and a temperature test module. The above composition is an existing compressor detector 1, and the existing The specific operating steps of the compressor tester 1 are as follows: first, the compressor tester 1 and the vehicle to be tested are connected through the pipeline module to form a detection channel, and then the pressure detection instruction or the temperature detection instruction is clicked in the display unit 2 to feed back the instruction information to the control module 3 through the communication connection, and the control module 3 starts the pressure test module and the temperature test module in the corresponding detection system 4 to detect the vehicle to be tested, and finally the detection system 4 displays the detection result information on the display unit 2 through the output module, wherein the step data of the test process of the pressure test module and the temperature test module in the detection system 4 are all displayed on the display unit 2 through the output module. When it is necessary to perform refrigerant detection on the compressor to be tested, it is necessary to use the refrigerant detection module 52 separately. This process requires additional operating steps and training of relevant personnel in operation level. For this reason, the utility model uses the compressor tester 1 in combination with the refrigerant detection module 52 to perform refrigerant detection on the vehicle to be tested, that is, the refrigerant detection unit 5 (i.e., the refrigerant detection module 52) is integrated into the original compressor tester 1, so that the refrigerant detection unit 5 is added to the original compressor tester 1;

[0019] The refrigerant detection unit 5 specifically includes a refrigerant detection instruction 51 and a refrigerant detection module 52 (the existing refrigerant filling, recycling and leak detection integrated machine will be collectively referred to as the refrigerant detection module 52 in this utility model), wherein the refrigerant detection instruction 51 is integrated into the detection selection module, and the refrigerant detection module 52 is integrated into the detection system 4, which adds the refrigerant detection unit 5 to the original compressor tester 1. There is no need for the operator to additionally add the existing refrigerant filling, recycling and leak detection integrated machine, and the detection process no longer requires manual operation in sequence according to the steps. The refrigerant detection can be completed by selecting the one-button start of the refrigerant detection unit 5 in the compressor tester 1, reducing the steps of manual operation of the refrigerant test. By starting the integrated compressor tester 1 with one button, the control module 3 controls the refrigerant detection module 52 to automatically perform refrigerant detection on the vehicle to be inspected.

[0020] The refrigerant detection module 52 specifically includes a refrigerant extraction module 521, a leakage detection module 522, a vacuum extraction module 523, a refrigerant quantity input module 524, a filling module 525 and an operation test module 526. The input end and one of the output ends of each module contained in the refrigerant detection module 52 are respectively communicated with one of the input ends and the output end of the control module 3, and the other output end of each module is connected to the input end of the output module. The other output end connected to the output module only transmits the operation process data, so that each module contained in the refrigerant detection module 52 is controlled in turn by the control module 3, and the movement process data of each module is fed back to the display unit 2 through the output module, so that the operator can understand the refrigerant replacement process more intuitively. The refrigerant extraction module 521 takes the refrigerant in the vehicle to be inspected. Extraction, the leakage detection module 522 performs leakage scanning detection after the refrigerant in the vehicle to be inspected is extracted to detect whether there is a leakage point, paving the way for the follow-up. Secondly, the vacuum extraction module 523 vacuums the vehicle to be inspected, so that the vehicle to be inspected is in a vacuum state to reduce subsequent environmental impacts. When the refrigerant quantity input module is started by the control module 3, the refrigerant quantity input module will be displayed in the display unit 2 under the action of the output module. By pre-entering the refrigerant quantity on the display unit 2 interface, the control module 3 controls the filling module 525 to pump in the pre-input amount of refrigerant, and the operation test module 526 is subject to the control module 3 for operation test. The old refrigerant is replaced by the above modules, the refrigerant environment is detected, and the standard value refrigerant is added for detection, so as to eliminate the influence of the refrigerant detection process and ensure the accuracy of the refrigerant test results.

[0021] The principle of the above-mentioned refrigerant detection unit 5 is explained as follows: when refrigerant detection is required, the operator first connects the pipeline module to the high and low pressure interfaces of the automobile air-conditioning system, and then only needs to click the refrigerant detection instruction 51 in the detection selection module of the display unit 2 interface. The display unit 2 feeds back the refrigerant detection instruction 51 information to the control module 3, and the control module 3 starts the refrigerant detection module 52. The control module 3 starts the modules included in the refrigerant detection module 52 in turn, and the other output end of each module feeds back the process data to the display unit 2 for real-time feedback. The order of the refrigerant detection module 52 is as follows:

[0022] 1. Start the refrigerant extraction module 521 to extract the original refrigerant from the vehicle to be inspected. The progress of the extraction process is fed back to the display unit 2 in real time, and the completion of the extraction is fed back to the control module 3;

[0023] 2. Control module 3 activates leakage detection module 522. The leakage detection module fills the chamber after the refrigerant is extracted with nitrogen and performs leakage detection with an electronic leak detector to ensure that there are no abnormalities in the refrigerant chamber.

[0024] 3. Control module 3 activates vacuum extraction module 523 to expel moisture and air from the refrigerant chamber, and feedback is sent to control module 3 upon completion of the extraction.

[0025] 4. The control module 3 starts the refrigerant quantity input module 524, wherein the display unit 2 displays the pre-input value instruction. After the pre-input value is input, the display unit 2 feeds back to the control module 3;

[0026] 5. The control module 3 starts the filling module 525, which fills the refrigerant chamber with the amount specified in the pre-input value instruction of the display unit 2;

[0027] 6. The control module 3 starts the operation detection module, which starts the vehicle to run and detects whether the refrigerant meets the standards; the test results are fed back to the display unit 2 through the output module;

[0028] After the above module steps are completed, they are fed back to the control module 3, which starts the control in sequence to complete the replacement of the old refrigerant and add the new standard value refrigerant for testing, thereby reducing the detection error.

[0029] Example 2: For the pre-input refrigerant value quantity, since the standard refrigerant values of different vehicle models are different, different standard refrigerant value quantities need to be input for different vehicle models. The operator needs to be trained to memorize the large number of standard refrigerant values in order to input them accurately and quickly. Based on the above problem, this embodiment proposes a matching module 527. The matching module 527 includes standard refrigerant values for several vehicle models. The input end of the matching module 527 is communicated with the vehicle-mounted system of the vehicle to be inspected, and the output end of the matching module 527 is connected to the control module 3. The matching module 527 matches and identifies the vehicle-mounted system of the vehicle to be inspected, and locks the vehicle model to be inspected and feeds it back to the control module 3. First, the operator connects the pipeline module to the high and low pressure interfaces of the air-conditioning system of the vehicle to be inspected. When the control module 3 starts the refrigerant input module, the control module 3 also obtains the vehicle result identified by the matching module 527 and automatically executes it, which not only realizes the need for manual input of pre-input refrigerant injection instructions, but also can match the corresponding refrigerant quantity value.
