[0002] The engine ignition coil seal plays a crucial role in the engine system. It is mainly used to prevent water and other impurities from entering the engine through the gap between the upper cover and the ignition coil, thus affecting the normal operation of the engine. However, when the engine is subjected to endurance testing on a test bench or when it is running with the vehicle for a long time, there is a risk that the ignition coil seal may detach from the upper cover, which may damage the engine's sealing and affect its performance. Therefore, it is essential to measure the pull-out force of the ignition coil seal.
[0003] In related technologies, specialized tooling is typically used to simulate the assembly of the engine cover and the sealing ring for pull-out force measurement.
[0004] However, the above methods cannot fully replicate real-world working conditions and environments, which can lead to errors in the test data during the testing process. As a result, it is impossible to effectively monitor the difference in pull-out force before and after the sealing ring rubber ages, thereby reducing the reliability of the verified parts. Summary of the Invention

[0026] The judgment subunit is used to determine whether the difference between the pull-out force data of the ignition coil seal ring and the preset design data is within a preset threshold range. If the difference between the pull-out force data of the ignition coil seal ring and the preset design data is within the preset threshold range, the reason for the detachment of the ignition coil seal ring is determined to be the aging of the ignition coil seal ring; otherwise, the reason for the detachment of the ignition coil seal ring is determined to be the deformation of the engine cover.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.
[0042] The following description, with reference to the accompanying drawings, illustrates an ignition coil seal pull-out force measurement system and method according to embodiments of this application. Addressing the issues mentioned in the background art regarding the inability of pull-out force measurement to fully replicate real-world operating conditions and effectively monitor the difference in pull-out force before and after seal rubber aging, thereby reducing the reliability of verified components, this application provides an ignition coil seal pull-out force measurement system. In this system, a pull-out force measurement assembly is mounted on an engine cover; a pressure sensing unit, also mounted on the pull-out force measurement assembly, measures the pressure signal when the ignition coil seal detaches; and a data acquisition unit is connected to the pressure sensing unit to convert the pressure signal into pressure data when the ignition coil seal detaches, thereby obtaining the pull-out force data of the ignition coil seal based on the pressure data. This solves the problems in the related art regarding the inability of pull-out force measurement to fully replicate real-world operating conditions and effectively monitor the difference in pull-out force before and after seal rubber aging, thereby reducing the reliability of verified components. By using a new ignition coil and a real engine cover for pull-out force measurement, the difference in pull-out force before and after seal rubber aging can be accurately monitored to verify the reliability of the components.
[0043] Specifically, Figure 1 This is a block diagram of an ignition coil seal pull-out force measurement system provided in an embodiment of this application.
[0044] like Figure 1 As shown, the ignition coil seal pull-out force measurement system 10 includes: a pull-out force measurement component 100, a pressure sensing unit 200, and a data acquisition unit 300.
[0045] The pull-out force measuring component 100 is mounted on the engine cover; the pressure sensing unit 200 is mounted in the pull-out force measuring component 100 and is used to measure the pressure signal when the ignition coil seal ring falls off; the data acquisition unit 300 is connected to the pressure sensing unit 200 and is used to convert the pressure signal into pressure data when the ignition coil seal ring falls off, so as to obtain the pull-out force data of the ignition coil seal ring based on the pressure data.
[0046] Optionally, the pull-out force measuring assembly 100 includes: a pull-out force measuring cylinder, which is connected to the pressure sensing unit 200 and contacts the inner side of the ignition coil sealing ring, for controlling the pressure signal generated by the pressure sensing unit 200 to meet the uniform distribution condition; a pull-out force measuring disc, which is connected to the pull-out force measuring cylinder and contacts the outer side of the ignition coil sealing ring, for cooperating with the pull-out force measuring cylinder to control the pressure signal generated by the pressure sensing unit 200 to meet the uniform distribution condition; and a pull-out force measuring plate, which is mounted on the engine cover for mounting and fixing at least one component to be measured.
[0047] Optionally, the ignition coil seal pull-out force measuring system 10 described above further includes: an ignition coil seal, which is connected to the engine cover and is used to control the pressure signal to be in a preset stable state.
[0048] Specifically, to address the risk of engine ignition coil seals detaching from the upper cover during durability tests or long-term operation, which could lead to decreased engine sealing performance, starting difficulties, insufficient power, and increased fuel consumption, this application uses a novel ignition coil seal and a real engine upper cover to measure the pull-out force. This replicates real-world operating conditions and environments, accurately monitoring the aging of the ignition coil seal rubber and the difference in pull-out force before and after aging. This verifies the reliability of the parts and significantly reduces the failure rate of engine sealing problems.
[0049] Specifically, such as Figure 2 As shown, the ignition coil seal pull-out force measurement system 10 of this application embodiment mainly includes an engine cover 1, a pull-out force measurement component 100, and an ignition coil seal 8. The pull-out force measurement component 100 is mounted on the engine cover 1, and the ignition coil seal 8 is connected to the engine cover 1 to control the pressure signal to be in a preset stable state. The pull-out force measurement component 100 includes a pull-out force measuring plate 2, a pull-out force measuring cylinder 6, a pull-out force measuring disc 7, a bolt assembly (i.e., long bolts 3, 4, and 9), and a pressure sensing unit 200 (i.e., a force sensor 5).
[0050] Furthermore, in this embodiment, the force sensing unit 200, the pull-out force measuring cylinder 6, the pull-out force measuring disc 7, and the ignition coil sealing ring 8 are assembled from the bottom of the engine cover 1 upwards. The pressure sensing unit 200 is assembled in the pull-out force measuring assembly 100, and a brand and model with a suitable range needs to be selected to measure the pressure signal when the ignition coil sealing ring 8 falls off. The pull-out force measuring cylinder 6 is connected to the pressure sensing unit 200 and contacts the inner side of the ignition coil sealing ring 8, used to control the pressure signal generated by the pressure sensing unit 200 to meet the uniform distribution condition. The pull-out force measuring disc 7 is connected to the pull-out force measuring cylinder 6 and contacts the outer side of the ignition coil sealing ring 8, used to cooperate with the pull-out force measuring cylinder 6 to control the pressure signal generated by the pressure sensing unit 200 to meet the uniform distribution condition. The pull-out force measuring disc 2 is assembled on the engine cover 1, used to install and fix other components to be measured in the ignition coil sealing ring pull-out force measuring system 10, and to maintain stability and consistency during measurement.
[0051] Optionally, the above-mentioned ignition coil seal pull-out force measuring system 10 further includes: a bolt assembly, which is fixedly assembled with the pull-out force measuring assembly 100 for fixing the pull-out force measuring assembly 100.
[0052] Optionally, the bolt assembly includes: a first bolt assembly, which is mounted on the engine cover to fix the pull-out force measuring plate horizontally aligned with the engine cover; and a second bolt assembly, which is vertically mounted at the center of the pull-out force measuring plate to apply pressure to the pressure sensing unit 200.
[0053] Optionally, the second bolt assembly further includes an adjustment unit connected to the second bolt assembly, used to adjust the screw-in depth of the second bolt assembly when the screw-in depth of the second bolt assembly does not meet the preset screw-in conditions.
[0054] The preset screw-in conditions can be set by those skilled in the art according to actual measurement needs, or they can be obtained through a limited number of computer simulation measurements, and are not specifically limited here.
[0055] Specifically, in this embodiment, the first bolt assembly (i.e., long bolts 3 and 4) is mounted on the engine cover 1 to fix the pull-out force measuring plate 2 on the engine cover 1, making the pull-out force measuring plate 2 horizontally aligned with the engine cover 1. The second bolt assembly (i.e., short bolt 9) is vertically mounted at the center of the pull-out force measuring plate 2, that is, the short bolt 9 is screwed into contact with the pressure sensing unit 200 through the pull-out force measuring plate 2, applying pressure to the pressure sensing unit 200. At this time, the pressure sensing unit 200 generates a pressure signal after receiving the force applied by the short bolt 9. At this time, the force is evenly transmitted to the ignition through the pull-out force measuring cylinder 6 and the pull-out force measuring disc 7. To avoid localized stress concentration, the pressure signal is not directly displayed. Therefore, the data acquisition unit 300 needs to convert the pressure signal into displayable and recordable pressure data. As the second bolt assembly is continuously screwed in, the force received by the pressure sensing unit 200 continuously increases, indicating that the pressure applied to the ignition coil seal 8 is continuously increasing. At this time, the pressure sensing unit 200 monitors and measures the pressure signal in real time until the ignition coil seal 8 is removed from the engine cover 1. The data acquisition unit 300 then collects the pressure signal generated by the pressure sensing unit 200 at this time, converts the pressure signal into pressure data, and records the pressure data as the pull-out force data of the ignition coil seal 8.
[0056] Furthermore, in order to accurately measure the pull-out force data of the ignition coil sealing ring 8, this embodiment also requires real-time monitoring of the screw-in position and screw-in depth of the bolt. When the screw-in position or screw-in depth of the second bolt assembly does not meet the preset screw-in conditions, the screw-in position and screw-in depth of the second bolt assembly are adjusted by the adjustment unit. For example, the screw-in position is adjusted by the adjustment components such as the positioning pin or positioning plate, the screw-in depth is adjusted by the components such as the stop ring or depth control device, or it is automatically adjusted by the position sensor. No specific limitation is made here. This avoids the misalignment of the second bolt assembly or abnormal screw-in force, thereby ensuring precise control.
[0057] Optionally, the above-mentioned ignition coil seal pull-out force measurement system 10 further includes: a data analysis unit, used to compare and analyze the pull-out force data of the ignition coil seal with historical data, and to obtain the cause of the ignition coil seal detachment based on the analysis results.
[0058] Optionally, the data analysis unit further includes: a judgment subunit, used to judge whether the difference between the pull-out force data of the ignition coil seal ring and the preset design data is within a preset threshold range. If the difference between the pull-out force data of the ignition coil seal ring and the preset design data is within the preset threshold range, the reason for the detachment of the ignition coil seal ring is determined to be the aging of the ignition coil seal ring; otherwise, the reason for the detachment of the ignition coil seal ring is determined to be the deformation of the engine cover.
[0059] The preset design data and preset threshold range can be set by those skilled in the art according to actual measurement needs, or obtained through a limited number of computer simulations, and are not specifically limited here.
[0060] Specifically, in this embodiment of the application, after obtaining the pull-out force data of the ignition coil sealing ring 8, it is necessary to compare and analyze the pull-out force data of the ignition coil sealing ring 8 with historical data, and obtain the cause of the ignition coil sealing ring falling off based on the analysis results.
[0061] Specifically, this application embodiment uses a novel ignition coil sealing ring 8 for pull-out force measurement tests. After obtaining pull-out force data from the novel ignition coil sealing ring 8, this pull-out force data is compared and analyzed with preset design data, such as R&D design values, to determine whether the difference between the pull-out force data of the ignition coil sealing ring 8 and the preset design data is within a preset threshold range, that is, whether the pull-out force data of the ignition coil sealing ring 8 closely matches the preset design data. If the difference between the pull-out force data of the ignition coil sealing ring 8 and the preset design data is within the preset threshold range, that is, the ignition coil sealing ring... If the pull-out force data of ignition coil seal 8 is close to the preset design data, it means that the engine cover 1 meets the usage requirements. At this time, it can be determined that the reason for the detachment of ignition coil seal 8 is that the ignition coil seal 8 is aging, which leads to the loosening of the frame and eventual detachment. If the difference between the pull-out force data of ignition coil seal 8 and the preset design data is not within the preset threshold range, that is, the pull-out force data of ignition coil seal 8 is much smaller than the preset design data, it means that the engine cover 1 does not meet the usage requirements. At this time, it can be determined that the reason for the detachment of ignition coil seal 8 is that the engine cover 1 is deformed, which leads to the detachment of ignition coil seal 8.
[0062] In summary, the ignition coil seal pull-out force measurement system 10 designed in this application is fully fitted with the seal rubber skeleton and the force is uniform, resulting in more accurate measured data and less risk of damaging the seal. Furthermore, the pull-out force measurement is based on a real engine cover, which replicates the actual working conditions and environment. The measured data is closer to the actual usage scenario, which helps to optimize the design and development of the seal rubber skeleton, define more applicable standards, and thus reduce production costs.
[0063] According to the ignition coil seal pull-out force measurement system of this application embodiment, a pull-out force measurement component is mounted on the engine cover; a pressure sensing unit mounted on the pull-out force measurement component is used to measure the pressure signal when the ignition coil seal falls off; a data acquisition unit is connected to the pressure sensing unit and is used to convert the pressure signal into pressure data when the ignition coil seal falls off, so as to obtain the pull-out force data of the ignition coil seal based on the pressure data. This solves the problems in related technologies where pull-out force measurement cannot completely reproduce real-world operating conditions, and effectively monitor the difference in pull-out force before and after seal rubber aging, thereby reducing the reliability of the verified parts. By using a new ignition coil and a real engine cover for pull-out force measurement, the difference in pull-out force before and after seal rubber aging can be accurately monitored to verify the reliability of the parts.
[0064] Next, referring to the accompanying drawings, a method for measuring the pull-out force of the ignition coil sealing ring according to an embodiment of this application is described.

[0071] If the difference between the pull-out force data of the ignition coil seal and the preset design data is within the preset threshold range, the cause of the ignition coil seal falling off is determined to be aging of the ignition coil seal; otherwise, the cause of the ignition coil seal falling off is determined to be deformation of the engine cover.
