[0026] According to one embodiment of the present invention, in conjunction with Figure 1-8A vehicle-mounted refrigerator performance testing mechanism 100 includes: a frame 10, a guide rail 20 disposed within the frame 10, a support plate 30 slidably disposed on the guide rail 20, a door opening and closing detection station 40 disposed within the frame 10, and an electrical performance testing station 50 slidably disposed on the guide rail 20.

[0027] The frame 10 serves as the mounting base for the remaining structural components of the entire testing mechanism. The frame 10 can be constructed by connecting aluminum profiles of appropriate specifications and dimensions, for example, by using various angle brackets and screws to connect the profiles together. Alternatively, in other embodiments, it can be directly constructed by welding angle irons together. The former offers sufficient flexibility, allowing for the replacement of profiles of different lengths to form frames of different sizes; while the latter, although lacking assembly flexibility, features a more stable welded structure due to the welding method used to fix the angle iron members, preventing wobbling during use.

[0028] The guide rail 20 is installed on the frame 10. Through the cooperation between the guide rail 20 and the tray 30, the tray 30 can slide on the frame 10. Since the vehicle refrigerator to be tested can be placed on the tray 30, the vehicle refrigerator can be moved to an appropriate position in the entire testing mechanism so as to carry out various performance tests, such as the electrical performance test and structural performance (mechanical performance) test of this utility model.

[0029] It should be noted that the guide rail 20 can take various forms, such as a dovetail groove structure guide rail or a T-shaped guide rail, and can even use a ball screw to realize the sliding of the tray 30. In this case, the drag bar 30 is fixed on the sliding nut of the ball screw, and the sliding nut is driven by the motor to move axially back and forth on the ball screw, thereby realizing the movement of the tray 30 and the vehicle refrigerator supported on the tray 30.

[0030] Here, the door opening and closing test station 40 is used to repeatedly open and close the door of the vehicle refrigerator at multiple frequencies in order to test the fatigue resistance of the door.

[0031] The electrical performance testing station 50 includes a platform 502, a mounting frame 504 disposed on the platform 502, a lifting mechanism 80, an automatic insertion module 90, and a barcode scanner 506 located on the mounting frame 504.

[0032] The following describes the testing process of the vehicle refrigerator performance testing organization.

[0033] First, the tray 30 moves from the outside to the inside of the frame 10 on the guide rail 20, specifically to the electrical performance testing station 50. Then, the vehicle refrigerator 200 to be tested is moved onto the platform 502 of the electrical performance testing station 50 via the tray 30. The barcode scanner 506 then scans the barcode on the vehicle refrigerator 200 to determine its specific identification data, such as model and type, ultimately locking in the product model. The lifting mechanism 80 lifts the tray 30 along with the vehicle refrigerator 200, allowing the automatic connection module 90 to electrically connect with the corresponding interface on the vehicle refrigerator 200, thus enabling the testing of various electrical performance parameters of the vehicle refrigerator 200. After testing, the vehicle refrigerator 200, along with the tray 30, moves along the guide rail 20 to the door opening / closing testing station 40. If the test result is satisfactory, the vehicle refrigerator 200 is moved out of the testing station and into the next testing station. If it fails, manual verification continues.

[0034] When mechanical performance testing of the vehicle refrigerator 200 is required, the model of the vehicle refrigerator 200 is first confirmed by scanning the vehicle refrigerator 200 with the barcode scanner 506. Then, the lifting mechanism 80 lifts the pallet 30 together with the vehicle refrigerator 200 on the pallet 30. The vehicle refrigerator 200 moves along with the pallet 30 to the door opening and closing detection station 40 on the guide rail 20. The door opening and closing detection station 40 is used to test the door opening stroke and the external force required to open the door of the vehicle refrigerator 200.

[0035] Preferably, the frame 10 includes an upper frame 12, a lower frame 14 longitudinally opposite to the upper frame 12, an electrical control box 16 located within the lower frame 14, a pneumatic circuit board 11, and a maintenance door 13 located within the upper frame 12. Here, the electrical control box 16 controls and drives the aforementioned components. By setting the frame 10 in a two-section structure, the production and installation of the entire frame 10 are greatly facilitated, and it is also convenient to assemble the remaining components within it. Multiple maintenance doors 13 are respectively located at different positions on the frame 10, so that when the vehicle refrigerator 200 needs maintenance, the maintenance doors at different positions can be directly opened to operate the refrigerator 200 with the aid of tools or equipment. It should be noted that the number and position of the maintenance doors can be flexibly adjusted according to the specific size and model of different vehicle refrigerators to be tested, and are not limited by this embodiment of the utility model.

[0036] Preferably, the frame 10 is further provided with a test module 104, a height adjustment module 106, and a moving module 108. After the barcode scanner scans the vehicle refrigerator 200 to determine its model, the height adjustment module 106 automatically adjusts the height of the tray 30 according to the model and external dimensions of the vehicle refrigerator 200, so that the height of the vehicle refrigerator 200 supported on the tray 30 is appropriately adjusted to a certain position, thereby matching the position of the test module 104, allowing the test module 104 to test the vehicle refrigerator 200. In addition, the moving module 108 is used to move the horizontal position of the tray 30, thereby adjusting the horizontal position of the vehicle refrigerator 200. More preferably, the tray 30 is further provided with a stop device 101, which functions similarly to a limit switch, to stop further movement after the tray 30 has moved to an appropriate horizontal position, thereby achieving a precise limiting function.

[0037] In one embodiment of this utility model, such as Figure 7 As shown, the mobile module 108 includes a slide plate 1082, a column 1084 disposed on the slide plate 1082, and a cross arm 1086 disposed on the top of the column 1084; the end of the cross arm 1086 is provided with a laser displacement sensor 1099, a pressure sensor 109, a pull pin 103, and a slide cylinder 105.

[0038] In this embodiment, the slide plate 1082 can move a distance in the horizontal direction. During testing, the slide cylinder 105 is activated first to complete the movement of the entire testing mechanism, and then the servo electric cylinder drives the test head to perform the test; the height of the Z-axis is automatically adjusted according to the product category switching in the program; a quick-change structure is formed by using a pull pin 103 and a slide groove, and the test fixture needs to be installed and disassembled when switching between manual and automatic products; an electric / pneumatic connection is used to facilitate the switching of fixtures when changing models.

[0039] In one embodiment, the specific process flow for testing the electrical performance of the vehicle-mounted refrigerator 200 is described as follows: The vehicle refrigerator under test moves to the electrical performance testing station (electrical performance testing station 50) along with the pallet, and the pallet 30 is automatically stopped by the stopper 101; then the lifting mechanism 80 moves upward, inserts the positioning pin into the positioning hole of the pallet 30, and lifts the pallet 30. The station automatically scans the product barcode (or reads the RFID of the accompanying tooling) and retrieves the test program; the equipment interacts with the HES system to verify the current status of the product under test (previous OK / NG); the equipment automatically extends the male connector (with XYZ three-way floating, which can float about 5mm) and connects with the female connector of the pallet 30; the equipment powers on the product, sends test instructions, and tests each item according to the "Test Item List": Detects software and hardware version numbers, heating current and power, cooling current and power, power consumption, and other parameters (depending on different customer needs).

[0040] After the test is completed, if NG is received, a prompt will be made asking whether to retest; if 0K is received, proceed to the next step. The test data and results are uploaded to the HES system, the device automatically retracts the male connector back to its original position, the lifting mechanism descends by 80 degrees, and the tray is released by 30 degrees.

[0041] In another embodiment, the specific process flow for testing the force performance of the vehicle-mounted refrigerator 200 is as follows: The product flows into the force performance testing station along with the pallet 30, which automatically stops. The lifting mechanism 30 moves upward, inserting the positioning pin into the positioning hole of the pallet 30, thereby lifting the pallet 30. The workstation automatically scans the product barcode (or reads the RFID of the accompanying tooling), retrieves the test program, and interacts with the MIS system to verify the current status of the product under test (previous OK / NG). The equipment automatically extends the male connector (with XY7 three-way floating, which can float about 5mm) to mate with the female connector of the pallet 30. The equipment powers on the product, sends test instructions, and tests each item according to the "Test Item List": testing the color of the door cover, comparing and verifying it with the product's MES code (error prevention), testing the door opening stroke + time, testing the closing force, testing the resistance + light push closing force, testing the anti-pinch force, and testing others (according to different customer needs).

[0042] After the test is completed, if NG is received, a prompt will be made asking whether to retest; if 0K is received, the next step will be performed, the test data and results will be uploaded to the MES system, the equipment will automatically retract the male connector back to its original position, the lifting mechanism 80 will descend, the pallet 30 will be released, the blocking cylinder will release, and the product will flow into the next station with the pallet 30.

[0043] The overall structure of the vehicle refrigerator performance testing mechanism provided by this utility model is relatively simple compared to the prior art, and the cost is low. The clamping and testing process of the workpiece (vehicle refrigerator) is simple and efficient.

Furthermore, other steps, measures, and solutions in the various operations, methods, and processes discussed in this application can also be alternated, modified, rearranged, decomposed, combined, or deleted. Furthermore, steps, measures, and solutions in the prior art that are similar to those disclosed in this application can also be alternated, modified, rearranged, decomposed, combined, or deleted.
