Description

Technical Field

[0001] This utility model relates to the field of vehicle display module technology, and in particular to an aging operation monitoring system for vehicle display modules. Background Technology

[0002] With the development of the automotive industry, the performance stability and reliability of in-vehicle display modules, as core components of vehicle infotainment systems, are receiving increasing attention. To ensure that in-vehicle display modules function properly under various environmental conditions and maintain stable performance during long-term use, aging tests and operational monitoring are crucial.

[0003] The high-quality requirements of automotive display modules place higher demands on product manufacturing and quality control. Most of these issues occur within the first few hours or tens of hours of use. Therefore, in addition to standard testing procedures, an aging-in test is usually required.

[0004] Currently, existing aging operation programs rely solely on regular inspections by personnel, which cannot promptly detect and record various abnormalities occurring during the aging process, making it difficult to determine the root cause of these abnormalities. Furthermore, aging test equipment is typically not equipped with fixed limit switches, posing a risk of the equipment falling off the workbench due to tangled power cords. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an aging operation monitoring system for vehicle display modules to address the shortcomings of existing technologies.

[0006] To achieve the above objectives, this utility model provides an aging operation monitoring system for vehicle display modules, including an information processing module, a network switch, and an aging test machine. The aging test machine is connected to the network switch, and the network switch is connected to the information processing module. The information processing module is used to collect and display test data obtained by the aging test machine from testing the vehicle display module.

[0007] The aging test machine has multiple test positions, each of which houses a vehicle display module. The vehicle display module is connected to the aging test machine. The aging test machine is mounted on a mounting frame, which has a fixing structure for securing the aging test machine to the mounting frame. The fixing structure includes a telescopic spring, a clamping plate, and a pull rod. The mounting frame has a placement groove, and the clamping plate is located within the placement groove. A through groove is formed on the wall of the placement groove. One end of the pull rod passes through the through groove and is connected to the side wall of the clamping plate. One end of the telescopic spring is connected to the middle of the through groove via a retaining ring, and the other end of the telescopic spring is connected to the clamping plate. The telescopic spring is sleeved on the pull rod.

[0008] The beneficial effects of this utility model are as follows: By connecting the aging test machine to a network switch and the network switch to an information processing module, when the aging test machine tests the vehicle display module, the information processing module will collect and display the test data obtained by the aging test machine during the test of the vehicle display module. The staff can view the abnormal data in real time during the aging test operation so as to discover defective products in time. At the same time, it is also helpful for the staff to track the cause of the abnormality. In addition, by opening a placement groove on the mounting bracket, by pulling the pull rod, the pull rod drives the clamping plate to move in the outward direction to expand the space between the placement groove and the clamping plate. Then, the aging test machine is placed in the placement groove, and the pull rod is released. Under the action of the telescopic spring, the clamping plate moves in the inward direction until it abuts against the side wall of the aging test machine, so as to limit and fix the aging test machine and reduce the risk of the aging test machine falling off the mounting bracket.

[0009] Preferably, the information processing module includes a monitoring host, a barcode scanner, and a display, wherein the barcode scanner, the display, and the network switch are respectively connected to the monitoring host.

[0026] Please see Figures 1 to 3 The vehicle display module aging operation monitoring system in this embodiment includes an information processing module, a network switch 20, and an aging test machine 30.

[0027] The aging test machine 30 is connected to the network switch 20 via the first network cable 70. The network switch 20 is connected to the information processing module. The aging test machine 30 is used to test the vehicle display module 60. The aging test machine 30 is equipped with a connection port, which is connected to the vehicle display module 60. It should be noted that the information processing module includes a monitoring host 10, a barcode scanner 50, and a display 40. The barcode scanner 50, the display 40, and the network switch 20 are respectively connected to the monitoring host 10, and the network switch 20 is connected to the monitoring host 10 via the second network cable 80. The barcode scanner is used to scan the QR code of the vehicle display module 60 to obtain the QR code information of the vehicle display module 60. The monitoring host 10 is used to control the start of the aging test machine 30, control the operation of the barcode scanner 50, and also control the start of the display 40. The display 40 is used to display the test data obtained by the aging test machine 30 in testing the vehicle display module 60, so that the staff can directly view it.

[0028] In this embodiment, the monitoring host 10 includes a signal receiving unit and an alarm unit. The signal receiving unit is connected to the alarm unit. The signal receiving unit is used to receive test signals sent by the aging test machine 30. There are two types of test signals: a normal signal and an abnormal signal. Specifically, when the vehicle display module 60 passes the test, the aging test machine 30 sends a normal signal. When the vehicle display module 60 fails the test, the aging test machine 30 sends an abnormal signal. It should be noted that the abnormal signal serves as an alarm signal for the alarm unit, so that the alarm unit can make an alarm response.

[0029] In this embodiment, the aging test machine 30 is provided with multiple partitions 31, which are evenly distributed and form test positions between adjacent partitions 31. Each test position can hold one vehicle display module 60. In other words, multiple vehicle display modules 60 can be placed on one aging test machine 30. The aging test machine 30 is provided with multiple connection ports, and each vehicle display module 60 is connected to the aging test machine 30 through different connection ports.

[0030] In this embodiment, the specific operation of performing aging test on the vehicle display module 60 is as follows: First, turn on the power of the aging test machine 30 and power on the monitoring host 10. The monitoring host 10 sends a command to the barcode scanner 50 through the network. The barcode scanner 50 scans the aging test machine 30 to obtain the number of the aging test machine 30 and the number of each connection port. The barcode scanner 50 scans the QR code of each vehicle display module 60 to obtain the QR code information of each vehicle display module 60. The number of the aging test machine 30, the QR code information of each vehicle display module 60 and the port information of each connection port are all recorded in the monitoring host 10, and the QR code information of each vehicle display module 60 is associated with the corresponding connection port number and the corresponding aging test machine 30.

[0031] At this time, the monitoring host 10 initiates a command to start the aging test machine 30 and begins timing. The aging test machine 30 illuminates all connected vehicle display modules 60 and plays the images in a loop, simultaneously sending the status of each connected port to the monitoring host 10. Afterward, the aging test machine 30 starts the real-time monitoring process:

[0032] The system monitors the operating current of the vehicle display module 60 in real time. If any abnormality occurs, the power supply to the vehicle display module 60 corresponding to the abnormal location is immediately cut off, and abnormal information and abnormal signals are sent to the monitoring host 10.

[0033] The status of the IC register in the vehicle display module 60 is scanned and read sequentially at regular intervals. If any abnormality occurs, abnormal information and abnormal signals are sent to the monitoring host 10.

[0034] The abnormal information includes: the number of the aging test machine 30, the abnormal connection port number, and the abnormal IC register address. After receiving the above information, the monitoring host 10 associates the abnormal information and the occurrence time with the QR code of the vehicle display module 60 and stores the relevant data in the SQL 2000 database.

[0035] When no abnormality occurs, a normal signal is sent to the monitoring host 10 at regular intervals.

[0036] It should be noted that the monitoring host 10 displays the monitoring status in real time and the aging runtime in real time. When it receives an abnormal signal sent by the aging test machine 30, it determines the location of the abnormal vehicle display module 60 based on the abnormal information and the source port, and changes its corresponding status to red. When it receives a normal signal sent by the aging test machine 30, it changes its corresponding status to yellow. According to the set alarm conditions, it promptly issues an alarm signal to prompt relevant personnel to handle the situation and saves the abnormal information record at the same time.

[0037] When the aging process ends, if no abnormalities occur, the product will proceed normally. If abnormalities occur, relevant personnel will analyze the abnormal products, determine the cause of the abnormality by combining the abnormal information saved in the system, and make corresponding improvements.

[0038] In this embodiment, the aging tester 30 is mounted on the mounting frame 90. The mounting frame 90 is provided with a fixing structure that fixes the aging tester 30 to the mounting frame 90. Specifically, the fixing structure includes a telescopic spring 94, a clamping plate 92, and a pull rod 93. The mounting frame 90 has a placement groove 91, and the clamping plate 92 is located in the placement groove 91. A through groove is provided on the groove wall of the placement groove 91. One end of the pull rod 93 passes through the through groove and extends to connect with the side wall of the clamping plate 92. The other end of the pull rod 93 is located on the outside of the mounting frame 90. A retaining ring 95 is provided in the middle of the through groove. The telescopic spring 94 is located between the retaining ring 95 and the clamping plate 92. One end of the telescopic spring 94 is connected to the retaining ring 95, and the other end of the telescopic spring 94 is connected to the retaining ring 95. The telescopic spring 94 is sleeved on the pull rod 93.

[0039] It should be noted that pulling the lever 93 causes the clamping plate 92 to move outward, compressing the telescopic spring 94 and placing the aging test machine 30 into the placement groove 91. Then, the lever 93 is released, and under the action of the telescopic spring 94, the clamping plate 92 moves inward until it abuts against the side wall of the aging test machine 30 to fix the aging test machine 30.

[0040] It should be noted that fixing the aging test machine 30 to the mounting frame 90 by fixing the structural components helps reduce the risk of the aging test machine 30 falling off the mounting frame 90. At the same time, placing multiple aging test machines 30 on the mounting frame 90 at the same time and performing testing operations simultaneously facilitates organization and summarization, and also makes it easier to connect multiple aging test machines 30 in an orderly manner, which helps to avoid the problem of wire tangling.

[0041] In practical implementation, by connecting the aging test machine 30 to the network switch 20, and connecting the network switch 20 to the information processing module, when the aging test machine 30 tests the vehicle display module 60, the information processing module will collect and display the test data obtained by the aging test machine 30 in testing the vehicle display module 60. The staff can view the abnormal data in real time during the aging test operation, so as to discover defective products in time. At the same time, it is also helpful for the staff to track the cause of the abnormality. Meanwhile, by opening a placement groove 91 on the mounting bracket 90, by pulling the pull rod 93, the pull rod 93 drives the clamping plate 92 to move in the outward direction, thereby expanding the space between the placement groove 91 and the clamping plate 92. Then, the aging test machine 30 is placed in the placement groove 91. The pull rod 93 is released, and under the action of the telescopic spring 94, the clamping plate 92 moves in the inward direction until it abuts against the side wall of the aging test machine 30, so as to limit and fix the aging test machine 30, thereby reducing the risk of the aging test machine 30 falling from the mounting bracket 90.

[0042] It should be noted that the above implementation process is only to illustrate the feasibility of this application, but it does not mean that the vehicle display module aging operation monitoring system of this application has only the above-mentioned single implementation process. On the contrary, as long as the vehicle display module aging operation monitoring system of this application can be implemented, it can be included in the feasible implementation scheme of this application.
