Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for testing the far magnetic field of automotive parts. Background Technology

[0002] Currently, regarding the setup of far-field transmission antennas, most international standards refer to SAE J551-5 Rev MAY2012, while the relevant national standard in China is GB / T 18387. Both standards clearly require testing the antenna in multiple directions.

[0003] Since the far-field antenna (ETS-Lindgren 6502) itself does not come with an antenna bracket, and no company has been found that specializes in researching and manufacturing such far-field antenna brackets, the lack of a dedicated testing bracket can lead to antenna height errors and inconsistent antenna placement during testing. This, in turn, affects the validity and reproducibility of the test results, resulting in significant discrepancies in the existing test results.

[0004] As is well known, laboratories must pursue quality, accuracy, and efficiency during testing. This is especially true for electromagnetic compatibility (EMC) testing of automotive electronic components, which places extremely stringent requirements on test setup. In far-field testing, there are very specific requirements regarding the placement and height of the far-field antenna; most automotive manufacturers even specify in their standards that the antenna must be tested in three directions. To meet these stringent testing conditions as much as possible, applicants currently have to expend considerable time and effort on antenna placement, measuring antenna height and distance, and changing antenna orientation. Even so, it is impossible to guarantee that this on-site setup will ensure precise consistency in antenna height and distance for every test.

[0005] Therefore, there is an urgent need for a unified and fixed antenna support and steering device that can meet the stringent testing conditions of the far magnetic field. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned limitations of the prior art by providing an antenna bracket for testing the far magnetic field of automotive parts, which enables error-free placement and movement of the antenna, thus providing precise testing conditions.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] An antenna bracket for testing the far magnetic field of automotive parts includes a support platform, a fixing plate, and a slot. The support platform has vertically intersecting cross-shaped grooves, and the center of each of the four directions of the cross-shaped grooves has the same first screw hole. The fixing plate is composed of a long rectangular plate and a short rectangular plate. The short rectangular plate is adapted to the straight groove of the cross-shaped groove, and the outer side of the long rectangular plate has a fixing groove for mounting the antenna base. The fixing plate has multiple second screw holes, located on opposite sides of the fixing groove. The slot is a concave slot, vertically fixed to the support platform, for inserting the long side of the fixing plate.

[0009] Furthermore, when the short rectangular plate of the fixing plate is placed in the straight groove of the cross-shaped groove, the central axes of the first screw hole and the second screw hole overlap. The first screw hole and the second screw hole are of the same type.

[0010] Furthermore, the slot has multiple screw holes at different heights on both sides of its side walls for adjusting the height of the locking plate.

[0011] The aforementioned antenna bracket for testing the far magnetic field of automotive parts further includes a column, an upper connecting plate, and a lower connecting plate. The upper connecting plate is connected to the top of the column, and the lower connecting plate is connected to the bottom of the column. The upper connecting plate has a groove with the same configuration as the cross-shaped groove on its upper surface for supporting a short rectangular plate. The bottom surface of the lower connecting plate is a boss, the size of which is adapted to the straight groove of the cross-shaped groove.

[0012] Furthermore, the bottom panel of the lower connecting plate is a boss, the size of which is adapted to the straight groove of the cross-shaped groove. The connecting plate is provided with a fourth screw hole. When the boss of the connecting plate is located in the straight groove of the cross-shaped groove, the central axis of the third screw hole and the first screw hole overlaps, and the third screw hole and the first screw hole have the same model.

[0013] The aforementioned antenna bracket for testing the far magnetic field of automotive parts also includes multiple bolt fasteners, which are used to lock the antenna mount on the mounting plate, the mounting plate on the support platform, the mounting plate on the slot, and the lower connecting plate on the support platform.

[0014] Furthermore, the vertical dimensions of the support platform, fixing plate, slot, column, upper connecting plate, and lower connecting plate are precisely consistent with the antenna placement requirements in the automotive parts far magnetic field testing standard after the connection, fixing, and adjustment of each part.

[0015] Furthermore, the support platform is equipped with pulleys with locking mechanisms at its bottom, allowing for free movement and positioning of the antenna sample.

[0016] The beneficial effects of this utility model are:

[0017] The antenna bracket for testing the far magnetic field of automotive parts provided by this utility model allows for convenient and quick switching of the antenna's direction and placement during the testing process, eliminating the need to measure the height of the far magnetic field antenna after each switch; it also ensures that the height of the antenna sample remains accurate and consistent during each test, greatly improving testing efficiency and accuracy.

[0018] The special bracket of this utility model is not only simple and convenient to use, but also reduces and avoids damage to the antenna during transportation, and can be transported freely between multiple test sites.

[0019] At the same time, this utility model has a simple structure, low manufacturing cost, and strong applicability.

[0031] The specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosed technical solutions. It should also be noted that, for ease of description, the accompanying drawings show only the parts relevant to the technical solutions of this application, not the entire structure.

[0032] Before discussing the exemplary embodiments in more detail, it should be mentioned that the structure of the device components and / or modules mentioned in the embodiments, unless otherwise described in detail, is something that can be understood by those skilled in the art based on existing public technologies or is a commercially available product.

[0033] refer to Figures 1-3 This embodiment provides an antenna bracket for testing the far magnetic field of automotive components, including a support platform 1, a fixing plate 2, and a slot 3. The support platform 1 has vertically intersecting cross-shaped grooves 101, and the same first screw hole 102 is provided at the center of each of the four directions of the cross-shaped grooves 101. The fixing plate 2 is composed of a long rectangular plate 201 and a short rectangular plate 202. The short rectangular plate 202 is adapted to the straight groove of the cross-shaped groove 101. The outer side panel of the long rectangular plate 201 has a fixing groove 201a for mounting the antenna base. The fixing plate 2 has a plurality of second screw holes 203, which are located on the opposite side of the fixing groove 201a. The slot 3 is a concave slot, vertically fixed to the support platform 1, for inserting the long side of the fixing plate 2.

[0034] When the short rectangular plate 202 of the fixing plate 2 is placed in the straight groove of the cross-shaped groove 101, the central axis of the first screw hole 102 and the second screw hole 203 overlaps, making it easier to lock them directly and simultaneously with bolt fasteners. At this time, the first screw hole 102 and the second screw hole 203 need to be the same model.

[0035] A preferred solution is to also provide multiple screw holes at different heights on both sides of the slot 3, so that the insertion height of the fixing plate 2 can be adjusted and then locked with bolt fittings.

[0036] refer to Figure 4 To further adapt to different standard requirements in various regions, a preferred solution is to set up a height adjustment mechanism, including a column 4, an upper connecting plate 5, and a lower connecting plate 6. The upper connecting plate 5 is connected to the top of the column 4, and the lower connecting plate 6 is connected to the bottom of the column 4. The upper connecting plate 5 has a groove with the same configuration as the cross-shaped groove 101 on its upper surface, which is used to support the short rectangular plate 202. The bottom surface of the lower connecting plate 6 is a boss, and the size of the boss is adapted to the straight groove of the cross-shaped groove 101.

[0037] The bottom panel of the lower connecting plate 6 is a boss, the size of which matches the straight groove of the cross-shaped groove 101. A fourth screw hole 601 is provided on the connecting plate 6. When the boss of the connecting plate 6 is located in the straight groove of the cross-shaped groove 101, the central axis of the third screw hole 601 and the first screw hole 102 overlaps. The third screw hole 601 and the first screw hole 102 are of the same type.

[0038] In addition, multiple bolt fasteners can be configured to lock the antenna mount on the mounting plate 2, the mounting plate 2 on the support platform 1, the mounting plate 2 on the slot 3, and the lower connecting plate 6 on the support platform 1 when needed.

[0039] The vertical dimensions of the support platform 1, fixing plate 2, slot 3, column 4, upper connecting plate 5, and lower connecting plate 6 are precisely consistent with the antenna placement requirements in the automotive parts far magnetic field testing standard after the connection, fixing, and adjustment of each part.

[0040] For example, the fixed plate height of 556.95mm meets the antenna centerline testing requirement of 1000mm, allowing testing of the antenna in both the X and Y directions. The column and connecting plate, being additional height components, are 305mm high and can be used to meet the antenna centerline testing requirement of 1300mm, also allowing testing of the antenna in both the X and Y directions. The slot height of 496.05mm meets the antenna Z-direction requirement and is adjustable vertically.

[0041] Furthermore, pulleys with locking mechanisms are installed at the bottom of the support platform 1 to facilitate free transfer and positioning of the antenna sample.

[0042] During testing, refer to Figure 1 The antennas are positioned and installed along the three axes. For example, after the antenna is initially fixed to the mounting plate, if a 90-degree rotation is required for testing (from position C to position B), simply install the mounting plate into the straight slot in the other 90-degree direction. When rotation to the Z direction is required, simply insert the mounting plate into the slot with a defined height.
