Its purpose is to ensure that the electronic systems in a vehicle can maintain stable operation when subjected to external electromagnetic interference, thereby guaranteeing the vehicle's safety and reliability. In EMS testing of headlights, it is necessary to monitor changes in headlight intensity at different angles and positions. However, in current testing systems, the position of the light intensity monitoring probe is usually fixed and cannot be flexibly adjusted. Utility Model Content

[0004] This application provides an adjustment bracket. The adjustment bracket includes a base. The adjustment bracket also includes a bamboo-joint tube connected to the base. The adjustment bracket also includes a clamp connected to the bamboo-joint tube. The clamp is used to hold a light intensity monitoring probe. The bamboo-joint tube is used to adjust the position and orientation of the light intensity monitoring probe during electromagnetic susceptibility testing of vehicle lights. The light intensity monitoring probe is used to monitor the luminous intensity of vehicle lights.

[0005] In one embodiment of this application, the bamboo-joint pipe includes a main pipe section and a branch pipe section, the branch pipe section being connected to the main pipe section, and the main pipe section and the branch pipe section being respectively connected to a clamp.

[0006] In one embodiment of this application, the diameter of the main pipeline section is larger than the diameter of the branch pipeline section.

[0007] In one embodiment of this application, the clamp includes: a main body connected to a bamboo tube, the main body having a clamping groove; and a clamping member movably disposed on the main body and embedded in the clamping groove, the clamping member being configured to cooperate with the groove wall of the clamping groove to clamp the light intensity monitoring probe.

[0008] In one embodiment of this application, the clamping member is threadedly connected to the body to adjust the length of the portion of the clamping member embedded in the clamping groove.

[0009] In one embodiment of this application, the clamp further includes: a first pad disposed at the end of the clamping member that is embedded in the clamping groove; and a second pad disposed on the groove wall of the clamping groove facing the clamping member, the first pad and the second pad being used to cooperate in clamping the light intensity monitoring probe.

[0010] In one embodiment of this application, the main body includes a first main body portion, a second main body portion, and a third main body portion.

It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0025] To address the technical problem that the position of light intensity monitoring probes in existing technologies is typically fixed and cannot be flexibly adjusted, one embodiment of this application provides an adjustment bracket. The adjustment bracket includes a base. It also includes a bamboo-joint tube connected to the base. Furthermore, it includes a clamp connected to the bamboo-joint tube, used to hold the light intensity monitoring probe. The bamboo-joint tube is used to adjust the position and orientation of the light intensity monitoring probe during electromagnetic susceptibility testing of vehicle lights. The light intensity monitoring probe is used to monitor the luminous intensity of the vehicle lights. This will be described in detail below.

[0026] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of an embodiment of the adjustment bracket of this application.

[0027] In one embodiment, the adjustment bracket 10 can be applied to electromagnetic susceptibility (EMS) testing of vehicle lamps. Specifically, the adjustment bracket 10 includes a base 11. The base 11 is the basic carrier of the adjustment bracket 10, and the adjustment bracket 10 is mounted on a testing system (such as the test table 21 mentioned below) via the base 11. The adjustment bracket 10 also includes a bamboo tube 12, which is connected to the base 11. The adjustment bracket 10 also includes a clamp 13, which is connected to the bamboo tube 12. The clamp 13 is used to hold a light intensity monitoring probe, and the bamboo tube 12 is used to adjust the pose (including angle and position) of the light intensity monitoring probe during the electromagnetic susceptibility testing of the vehicle lamp. The light intensity monitoring probe is used to monitor the luminous intensity of the vehicle lamp.

[0028] In electromagnetic susceptibility testing of vehicle headlights, it is necessary to monitor changes in light intensity at different angles and positions. In this embodiment, the bamboo-joint tube 12 of the adjusting bracket 10 enables multi-degree-of-freedom adjustment of the light intensity monitoring probe, including movement and rotation in the up-down, left-right, and forward-backward directions. This flexibility allows the light intensity monitoring probe to be quickly adjusted to the optimal position to adapt to different testing scenarios and headlight configurations. The adjusting bracket 10 can precisely adjust the angle and position of the light intensity monitoring probe, ensuring that it is accurately aligned with the headlight's light intensity measurement point. This precise positioning capability helps improve the accuracy of light intensity measurement, thus providing more reliable light intensity data for electromagnetic susceptibility testing. Since headlight designs may vary significantly across different vehicle models, the versatility and adjustability of the adjusting bracket 10 in this embodiment allow it to adapt to the installation requirements of various headlights. Whether it's a traditional halogen lamp, xenon lamp, or a modern LED headlight or matrix headlight, the light intensity monitoring probe can be stably fixed using the adjusting bracket. In electromagnetic susceptibility testing, it may be necessary to adjust the position of the light intensity monitoring probe multiple times to verify changes in light intensity under different conditions. The rapid adjustment capability of the adjustment bracket 10 in this embodiment can significantly reduce test preparation time and improve overall test efficiency. The stability of the adjustment bracket 10 ensures that the light intensity monitoring probe remains fixed during testing, avoiding measurement errors caused by positional shifts. This stability is crucial for obtaining accurate light intensity data, especially in high-precision electromagnetic susceptibility testing. In complex test scenarios, such as simulating dynamic light intensity changes during vehicle movement, the bamboo-joint tube 12 of the adjustment bracket 10 can flexibly adjust the position and orientation of the light intensity monitoring probe to adapt to the dynamic illumination range of the vehicle headlight. This capability is critical for evaluating the performance of the vehicle headlight under different operating conditions.

[0029] It should be noted that the bamboo-joint tube 12 in this embodiment is bendable and adjustable at multiple angles. The bamboo-joint tube 12, in conjunction with the clamp 13, can flexibly adjust the position and orientation of the light intensity monitoring probe, and can allow the light intensity monitoring probe to hover at any angle and position. The structural principle of the bamboo-joint tube 12 is within the understanding of those skilled in the art, and will not be elaborated here.

[0030] Please refer to the following: Figure 2 , Figure 2 This is a schematic diagram of the structure of one embodiment of the fixture of this application.

[0031] In one embodiment, the clamp 13 includes a main body 131 and a clamping member 133. The main body 131 is connected to the bamboo tube 12 and has a clamping groove 132. The clamping member 133 is movably disposed on the main body 131 and is embedded in the clamping groove 132. The clamping member 133 is configured to cooperate with the groove wall of the clamping groove 132 to clamp the light intensity monitoring probe.

[0032] In this embodiment, the clamping groove 132 and the movable clamping member 133 cooperate to reliably clamp the light intensity monitoring probe. The fit between the clamping member 133 and the groove wall of the clamping groove 132 can accommodate light intensity monitoring probes of different sizes. By adjusting the position (e.g., the embedding depth) of the clamping member 133, light intensity monitoring probes of different specifications can be clamped, improving the versatility of the fixture 13. At the same time, the movable clamping member 133 facilitates quick installation and removal of the light intensity monitoring probe, enhancing the convenience of testing operations.

[0033] Specifically, the clamping member 133 is threadedly connected to the main body 131 to adjust the length of the portion of the clamping member 133 embedded in the clamping groove 132, thereby precisely controlling the clamping force and clamping position of the light intensity monitoring probe. This structure not only ensures the stability of the light intensity monitoring probe, minimizing the possibility of it loosening or falling off, but also adapts to light intensity monitoring probes of different sizes, further improving the versatility and adjustment accuracy of the clamp 13, and ensuring the stability of the light intensity monitoring probe during complex pose adjustments.

[0034] For example, the main body 131 includes a first main body portion 136, a second main body portion 137, and a third main body portion 138. The second main body portion 137 and the third main body portion 138 are respectively disposed at opposite ends of the first main body portion 136, and the first main body portion 136, the second main body portion 137, and the third main body portion 138 cooperate to form a clamping groove 132. The first main body portion 136 is connected to the bamboo joint tube 12. The first main body portion 136 and the bamboo joint tube 12 can be connected by a threaded connection. For example, a fixing hole 1361 is provided on the first main body portion 136, and a stud is provided at the end of the bamboo joint tube 12. The first main body portion 136 and the bamboo joint tube 12 are connected and fixed by the fixing hole 1361 and the stud. The other end of the bamboo joint tube 12 can also have a stud, and the bamboo joint tube 12 is locked in the threaded hole of the base 11 by the stud thereon. The clamping member 133 is movably disposed on the second main body 137, and is configured to cooperate with the third main body 138 to clamp the light intensity monitoring probe. A threaded hole may be provided on the second main body 137, through which the clamping member 133 is threadedly connected to the second main body 137 to adjust the length of the portion of the clamping member 133 embedded in the clamping groove 132. The clamping member 133 can be a screw made of plastic, etc. On the one hand, the clamping member 133 can be threadedly connected to the main body 131; on the other hand, the clamping member 133 is made of non-metallic material, avoiding interference from metallic materials on the electromagnetic environment (such as electromagnetic shielding or signal reflection), ensuring the authenticity of electromagnetic interference signals and the accuracy of monitoring data in vehicle headlight EMS testing. Non-metallic materials also have the advantages of being lightweight and highly corrosion-resistant, facilitating long-term use, and are especially suitable for testing scenarios with extremely high electromagnetic sensitivity requirements.

[0035] It should be noted that the adjustment bracket 10 can be made entirely of non-metallic material to avoid interference from metallic materials on the electromagnetic environment (such as electromagnetic shielding or signal reflection), ensuring the authenticity of electromagnetic interference signals and the accuracy of monitoring data in vehicle headlight EMS testing. Non-metallic materials also have the advantages of being lightweight and highly corrosion-resistant, facilitating long-term use, and are especially suitable for testing scenarios with extremely high electromagnetic sensitivity requirements.

[0036] In one embodiment, the clamp 13 further includes a first pad 134 and a second pad 135. The first pad 134 is disposed at the end of the clamping member 133 that is embedded in the clamping groove 132. The second pad 135 is disposed on the groove wall of the clamping groove 132 facing the clamping member 133, specifically, the second pad 135 may be disposed on the surface of the third main body 138 facing the clamping groove 132. The first pad 134 and the second pad 135 are used to cooperate in clamping the light intensity monitoring probe.

[0037] By using the above method, the first shim 134 and the second shim 135 increase the friction between the clamping member 133 and the light intensity monitoring probe, as well as between the groove wall and the light intensity monitoring probe, preventing the light intensity monitoring probe from sliding due to vibration or posture adjustment during the test. On the other hand, the first shim 134 and the second shim 135 can buffer the clamping force, avoiding damage (such as scratches or extrusion deformation) to the surface of the light intensity monitoring probe caused by rigid clamping, protecting the integrity of the light intensity monitoring probe, and ensuring the reliability of the monitoring data.

[0038] Please refer to the following: Figure 3 , Figure 3 This is a schematic diagram of another embodiment of the adjustment bracket of this application.

[0039] In an alternative embodiment, the difference between this embodiment and the above embodiment is that the bamboo joint pipe 12 in this embodiment includes a main pipe section 121 and a branch pipe section 122. The branch pipe section 122 is connected to the main pipe section 121, and the main pipe section 121 and the branch pipe section 122 are respectively connected to clamps 13.

[0040] Through the above-described method, this embodiment, with its main road section 121 and branch road section 122 design, allows the adjusting bracket 10 to simultaneously connect to multiple clamps 13 (i.e., multiple light intensity monitoring probes). This enables synchronous monitoring of vehicle headlight light intensity changes from different locations (corresponding positions / angles on the main road and branch road), improving the comprehensiveness and richness of the test data. It is particularly suitable for complex test scenarios requiring multi-dimensional, multi-point synchronous monitoring, avoiding the time-consuming problem of repeatedly adjusting a single probe and further improving test efficiency.

[0041] Furthermore, the diameter of the main pipeline section 121 is larger than that of the branch pipeline section 122, giving the main pipeline section 121 stronger structural support and stability (for example, to support heavy light intensity monitoring probes), while the branch pipeline section 122 has a smaller diameter and is more flexible, facilitating precise adjustment of the position of local light intensity monitoring probes. This design balances the overall stability of the adjustment bracket 10 with the flexibility of local adjustments, ensuring a reasonable division of labor between primary and secondary probes during installation, and avoiding the problems of "excessive rigidity in the main pipeline" or "insufficient rigidity in the branch pipeline" caused by uniform pipe diameter.

[0042] Please refer to the following: Figure 4 , Figure 4 This is a schematic diagram of the structure of one embodiment of the test system of this application.

[0043] In one embodiment, the testing system includes a light intensity monitoring probe and an adjustment bracket 10, with the light intensity monitoring probe clamped in a fixture 13 of the adjustment bracket 10. Specifically, the testing system also includes a test table 21, a support 22, a power supply 23, a power network 24, and an optical fiber 25. The sample under test 31 (e.g., a vehicle headlight) and the wiring harness 32 under test are arranged on the support 22 (e.g., a 50mm thick low-dielectric-constant insulating support), and the positive and negative terminals of the power supply 23 supply power to the sample under test 31 through the power network 24. The light intensity monitoring probe is fixed in the fixture 13 of the adjustment bracket 10, with the light intensity monitoring probe close to the sample under test 31. The adjustment bracket 10 is placed on the test table 21, and the light intensity monitoring probe is connected to the back-end processing equipment through the optical fiber 25.

[0044] In summary, this application provides an adjustment bracket and a testing system. A clamp is connected to a bamboo-joint tube, which holds a light intensity monitoring probe. The bamboo-joint tube is used to adjust the orientation of the light intensity monitoring probe during electromagnetic susceptibility testing of vehicle lights. The light intensity monitoring probe monitors the luminous intensity of the vehicle lights. In other words, by using a bamboo-joint tube, this application can flexibly adjust the orientation of the light intensity monitoring probe, thereby meeting the requirement of monitoring light intensity changes at different angles and positions during EMS testing of vehicle lights. The flexibility in adjusting the orientation of the light intensity monitoring probe allows it to be quickly adjusted to the optimal position to adapt to different testing scenarios and vehicle light configurations. The adjustment method provided by the bamboo-joint tube in this application allows for rapid adjustment of the light intensity monitoring probe's orientation, significantly reducing test preparation time and improving overall testing efficiency. Especially in complex testing scenarios, such as simulating dynamic light intensity changes during vehicle movement, the bamboo-joint tube can flexibly adjust the orientation of the light intensity monitoring probe to adapt to the dynamic illumination range of the vehicle lights. This capability is crucial for evaluating the performance of vehicle lights under different operating conditions. The adjustment bracket of this application has low manufacturing cost and convenient parts procurement.
