Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a high-temperature durability testing device for ignition coils. Background Technology

[0002] An ignition coil is an engine component that generates pulsed high-voltage electricity. An external signal is transmitted to the ignition coil through pins on the power plug. The ignition trigger module is triggered according to the external signal, thereby causing the ignition coil coil assembly to generate pulsed high voltage. The high-temperature durability test of the ignition coil is the main test to verify whether the reliability and service life of the ignition coil assembly meet the requirements. The closer the test device is to the actual installation and working environment and design service life of the ignition coil assembly, the higher the accuracy of the test results. To facilitate the seizure test, an ignition coil test device is needed.

[0003] However, existing ignition coil testing equipment has the following drawbacks:

[0004] Existing ignition coil testing equipment has weak high-temperature durability. During traditional ignition coil testing, high-voltage arcing and sparking occur between ignition coil assemblies and between the upper and lower discharge needles, which can easily interrupt the test and reduce the durability of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature durability testing device for ignition coils to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature durability testing device for ignition coils, comprising:

[0007] An insulating upper mounting plate has a high-temperature resistant component fitted inside it. The high-temperature resistant component consists of a mounting post, a metal sleeve, a support rod, an upper discharge needle, a lower discharge needle mounting plate, and a lower discharge needle. The outer surface of the metal sleeve is fitted inside the insulating upper mounting plate. A mounting post is provided at the top of the insulating upper mounting plate. A support rod is fixedly connected to the bottom of the insulating upper mounting plate. A lower discharge needle mounting plate is fixedly connected to the bottom of the support rod. A lower discharge needle is fixedly connected to the top of the lower discharge needle mounting plate. Insulating support plates are fixedly connected to both ends of the top of the lower discharge needle mounting plate. An insulating upper discharge needle mounting plate is provided at the top of the insulating support plate.

[0008] The mounting assembly comprises a mounting groove, a mounting slider, a mounting block, a limiting ring, and a handle. The top of the insulating support plate has a mounting groove, and the mounting slider is slidably connected inside the mounting groove. The mounting block is fixedly connected to the side of the mounting slider. The bottom of the insulating upper discharge needle mounting plate is fixedly connected to a limiting ring, and the side of the insulating upper discharge needle mounting plate is fixedly connected to a handle.

[0009] Optionally, the number of support rods is four, and the tops of the four support rods are evenly arranged at the four bottom corners of the insulating upper mounting plate. The four support rods can support and fix the insulating upper mounting plate.

[0010] Optionally, the inner wall of the mounting groove is provided with a mounting slot, and the outer surface of the mounting block is engaged with the inside of the mounting slot. When the mounting block is engaged with the inside of the mounting slot, the mounting slot limits the mounting block, fixing the position of the mounting block inside the mounting slot, thereby stabilizing the position of the insulating discharge needle mounting plate and completing the installation of the insulating discharge needle mounting plate.

[0011] Optionally, the number of upper discharge needles is three, and the number of lower discharge needles is three. With the setting of three upper discharge needles and three lower discharge needles, the installation distance between them is designed to be sufficient to prevent high-voltage arcing.

[0013] Optionally, the upper and lower discharge needles are aligned vertically, which allows for convenient and rapid testing.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This high-temperature durability testing device for ignition coils, through the design of high-temperature resistant components, features mounting posts and metal sleeves. During use, the mounting posts fix the ignition coil's position during the high-temperature durability test, while the metal sleeves ensure the high-voltage connecting pipes on the ignition coil assembly more closely resemble the actual working environment, resulting in higher test accuracy. The device's mounting components consist of a mounting groove, a mounting slider, a mounting clip, a limiting ring, and a handle. During use, the handle is held to slide the mounting slider into the mounting groove, which simultaneously limits its position. When the mounting clip engages with the groove on the inner wall of the mounting groove, it stabilizes the slider's position, thus fixing the mounting plate. The limiting ring then limits the position of the discharge needle, improving installation efficiency and preventing the mounting plate from shifting or loosening during installation, which could affect the test progress and reduce efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4As shown, this utility model provides a technical solution: a high-temperature durability testing device for ignition coils, comprising:

[0023] An insulating upper mounting plate 1 has a high-temperature resistant component 2 sleeved inside it. The high-temperature resistant component 2 consists of a mounting post 201, a metal sleeve 202, a support rod 203, an upper discharge needle 204, a lower discharge needle mounting plate 205, and a lower discharge needle 206. The outer surface of the metal sleeve 202 is fitted inside the insulating upper mounting plate 1. The top of the insulating upper mounting plate 1 is provided with the mounting post 201, and the bottom of the insulating upper mounting plate 1 is fixedly connected to the support rod 203. The bottom of the support rod 203 is fixedly connected to the lower discharge needle mounting plate 205, and the lower discharge needle... The top of the mounting plate 205 is fixedly connected to a lower discharge needle 206. Insulating support plates 207 are fixedly connected to both ends of the top of the lower discharge needle mounting plate 205. An insulating upper discharge needle mounting plate 208 is installed on the top of the insulating support plate 207. The test apparatus is designed with mounting posts 201 and metal sleeves. During the high-temperature durability test of the ignition coil assembly, the mounting posts 201 fix the ignition coil's mounting position, and the metal sleeves make the high-voltage connecting pipe on the ignition coil assembly more closely resemble the actual working environment throughout the test, resulting in higher accuracy of the test results. Since the ignition coil assembly needs to simulate the grounding of the entire vehicle engine during the high-temperature durability test, conductive metal materials are used for the mounting posts 201, metal sleeves, support rods 203, upper discharge needle 204, lower discharge needle 206, and lower discharge needle mounting plate 205. Furthermore, during the high-temperature durability test of the ignition coil assembly, the ignition coil assembly must simulate the working state of high-voltage ignition generated on the vehicle engine. In order to solve the problem of high-voltage arcing and sparking between the three ignition coil assemblies and between the three upper discharge needles 204, which would prevent the test from being carried out or interrupted, the upper mounting plate, upper discharge needle mounting plate, and support plate are made of high-temperature resistant insulating materials. The installation distance between the three ignition coil assemblies and between the three upper discharge needles 204 is designed to be a sufficient safety distance to prevent high-voltage sparking.

[0024] Mounting component 3 consists of mounting groove 301, mounting slider 302, mounting block 303, limiting ring 304, and handle 305. The top of the insulating support plate 207 has mounting groove 301, and mounting slider 302 is slidably connected inside the mounting groove 301. Mounting block 303 is fixedly connected to the side of mounting slider 302. The bottom of the insulating upper discharge needle mounting plate 208 is fixedly connected to the limiting ring 304, and the side of the insulating upper discharge needle mounting plate 208 is fixedly connected to the handle 305. Holding the handle 305, the mounting slider 302 is slid into the mounting groove 301. At the same time, the mounting groove 301 limits the mounting slider 302. When the mounting block 303 is engaged in the slot on the inner wall of the mounting groove 301, the position of the mounting slider 302 can be stabilized, thereby fixing the position of the mounting plate. At this time, the limiting ring 304 can limit the position of the discharge needle.

[0025] There are four support rods 203. The tops of the four support rods 203 are evenly arranged at the four bottom corners of the insulating upper mounting plate 1. The four support rods 203 can support and fix the insulating upper mounting plate 1.

[0026] The inner sidewall of the mounting groove 301 is provided with a mounting slot 4. The outer surface of the mounting block 303 is engaged with the inside of the mounting slot 4. When the mounting block 303 is engaged into the inside of the mounting slot 4, the mounting slot 4 limits the mounting block 303, so that the position of the mounting block 303 is fixed inside the mounting slot 4, thereby stabilizing the position of the insulating upper discharge needle mounting plate 208 and completing the installation of the insulating upper discharge needle mounting plate 208.

[0027] There are three upper discharge needles 204 and three lower discharge needles 206. The installation distance between the three upper discharge needles 204 and the three lower discharge needles 206 is designed to be sufficient to prevent high voltage arcing.

[0028] There are two insulating support plates 207. The two insulating support plates 207 are respectively set at the top ends of the lower discharge needle mounting plate 205. The two insulating support plates 207 can support and limit the insulating upper discharge needle mounting plate 208.

[0029] The upper discharge needle 204 and the lower discharge needle 206 are aligned vertically, which allows for convenient and rapid testing.

[0030] In this invention, the working steps of the device are as follows:

[0031] The first step involves designing a mounting post 201 and a metal sleeve on the test apparatus. These components ensure the ignition coil assembly is in a stable position during the high-temperature durability test. The mounting post 201 fixes the ignition coil's mounting position, while the metal sleeve makes the high-voltage connecting pipe on the ignition coil assembly more closely resemble the actual working environment throughout the test, resulting in higher accuracy of the test results. Since the ignition coil assembly needs to simulate the grounding of the entire vehicle engine during the high-temperature durability test, conductive metal materials are used for the mounting post 201, metal sleeve, support rod 203, upper discharge needle 204, lower discharge needle 206, and lower discharge needle mounting plate 205. Furthermore, during the high-temperature durability testing of the ignition coil assembly, the ignition coil assembly must simulate the working state of high-voltage ignition generated on the vehicle engine. In order to solve the problem of high-voltage arcing and sparking between the three ignition coil assemblies and the three upper discharge needles 204, which would prevent the test from being carried out or interrupted, the upper mounting plate, upper discharge needle mounting plate, and support plate are made of high-temperature resistant insulating materials. The installation distance between the three ignition coil assemblies and the three upper discharge needles 204 is designed to be a sufficient safety distance to prevent high-voltage arcing. By holding the handle 305, the mounting slider 302 is slid into the mounting groove 301. At the same time, the mounting groove 301 limits the mounting slider 302. When the mounting clip 303 is inserted into the slot on the inner wall of the mounting groove 301, the position of the mounting slider 302 can be stabilized, thereby fixing the position of the mounting plate. At this time, the limiting ring 304 can limit the position of the discharge needle.

[0032] The second step: The four support rods 203 support and fix the insulating upper mounting plate 1. When the mounting block 303 is inserted into the mounting slot 4, the mounting slot 4 limits the mounting block 303, fixing its position inside the mounting slot 4, thereby stabilizing the position of the insulating upper discharge needle mounting plate 208 and completing the installation of the insulating upper discharge needle mounting plate 208. The installation distance between the three upper discharge needles 204 and the three lower discharge needles 206 is designed to be sufficient to prevent high voltage arcing. The two insulating support plates 207 support and limit the insulating upper discharge needle mounting plate 208. Because the upper discharge needles 204 and the lower discharge needles 206 are aligned vertically, the test can be carried out conveniently and quickly.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
