[0044] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. To simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present application.

[0045] As the degree of electrification of automobiles increases, the issue of electromagnetic protection for the human body in vehicles has attracted increasing attention. For this reason, most automotive electronic component electromagnetic compatibility tests have added tests for electromagnetic protection of the human body. Most automobile manufacturers use a handheld electromagnetic radiation tester (hereinafter referred to as the tester) to measure electronic components and simulate the electromagnetic field intensity that passengers are exposed to under real vehicle conditions. However, the applicant has found that the tester itself has a certain weight, and it is easy to get fatigued when operating it for a long time on a tested component with a large number of test points. When using the tester for testing, in order to ensure the timeliness and accuracy of the test data (taking the maximum value measured in real time as the test result), it is difficult for one person to operate the tester and record and store the test data at the same time. When testing some tested samples for electromagnetic protection of the human body, one person cannot observe the test phenomenon while testing.

[0046] In view of this, an embodiment of the present application provides an electromagnetic protection test device. Please refer to Figure 1 and Figure 2 , Figure 1 which schematically shows the structural diagram of the electromagnetic protection test device provided by the embodiment of the present application; Figure 2Schematically shows the structural schematic diagram of the displacement component and the attitude adjustment component in the electromagnetic protection test device provided by the embodiment of the present application. An electromagnetic protection test device provided by the present application includes: a base 100, a controller (not shown in the figure), a displacement component 300, an attitude adjustment component 400, and a tester 500. Among them, the displacement component 300 is arranged on the base 100 and is electrically connected to the controller. The attitude adjustment component 400 is connected to the displacement component 300 and is electrically connected to the controller. The tester 500 is connected to one end of the attitude adjustment component 400 away from the displacement component 300. Specifically, the base 100 provides stable support for the entire device, ensuring that during the test, the displacement component 300, the attitude adjustment component 400, and the tester 500 will not affect the test accuracy due to shaking or displacement. The displacement component 300 is arranged on the base 100 and can achieve precise displacement control under the instruction of the controller, enabling the tester 500 to reach different test positions. The attitude adjustment component 400 is connected to the displacement component 300 and is also controlled by the controller, and can flexibly adjust the angle and attitude of the tester 500 to ensure a comprehensive and non-blind-spot electromagnetic protection test on the object under test 600 and obtain more comprehensive and accurate test data. Moreover, the controller is electrically connected to both the displacement component 300 and the attitude adjustment component 400, realizing the automatic control of the entire test process. The tester only needs to set relevant parameters on the controller, such as displacement distance, adjustment angle, and test time, etc., and the electromagnetic protection test device can run automatically without frequent manual operations by the tester, greatly improving the test efficiency and reducing the errors caused by manual operations.

[0047] In this way, in the embodiment of the present application, the direction and angle are flexibly adjusted through the displacement component 300 and the attitude adjustment component 400, and the position and attitude of the tester 500 are precisely controlled, so that the tester 500 can adapt to objects under test 600 with different shapes, sizes, and positions, as well as multiple test points of the object under test 600, ensuring the accuracy and reliability of the test results; secondly, the controller centrally controls the test parameters, realizes automatic control, simplifies the operation process, reduces manual intervention, improves the test efficiency and reduces operation errors; in addition, through automatic control and precise adjustment, it is ensured that the test conditions are consistent, the results are repeatable, which is convenient for comparative analysis and long-term monitoring, and improves the test efficiency.

[0048] Please refer to again Figure 1, in some embodiments, the displacement assembly 300 includes: a first cylinder 310, a second cylinder 320, a third cylinder 330, and a fourth cylinder 340. The first cylinder 310 is connected to the base 100; the second cylinder 320 is connected to the first cylinder 310, and the second cylinder 320 can move relative to the first cylinder 310 along the first direction X; the third cylinder 330 is connected to the second cylinder 320, and the third cylinder 330 can move relative to the second cylinder 320 along the second direction Y; the third cylinder 330 has a rotation axis 331 along the third direction Z, and the third cylinder 330 can rotate about the rotation axis 331. The first direction X, the second direction Y, and the third direction Z intersect pairwise; the fourth cylinder 340 is connected to one end of the third cylinder 330 away from the second cylinder 320, and the fourth cylinder 340 expands and contracts along the third direction Z. Specifically, in this application, the first cylinder 310 is connected to the base 100 to build the basic support for the entire displacement assembly 300 and the attitude adjustment assembly 400. The second cylinder 320 can move relative to the first cylinder 310 along the first direction X, the third cylinder 330 can move relative to the second cylinder 320 along the second direction Y, and the fourth cylinder 340 expands and contracts along the third direction Z. This enables the tester 500 to be accurately positioned in three-dimensional space, meeting the position requirements of different test points in the X, Y, and Z directions, greatly improving the comprehensiveness and accuracy of the test, and ensuring a full-range detection of the electromagnetic protection performance of the object under test 600. Secondly, in electromagnetic protection testing, different test angles may affect the reception and analysis of electromagnetic signals. This flexible angle adjustment ability helps to obtain richer test data and deeply analyze the electromagnetic protection characteristics of the object under test 600. In addition, through the coordinated operation of the first cylinder 310, the second cylinder 320, the third cylinder 330, and the fourth cylinder 340, the displacement assembly 300 can adapt to various complex test scenarios. By adjusting the motion parameters of the first cylinder 310, the second cylinder 320, the third cylinder 330, and the fourth cylinder 340, the tester 500 can reach the ideal test position and angle, improving the versatility and adaptability of the test device. Again, as a common pneumatic actuator, the cylinder has the characteristic of fast response speed. During the test, when it is necessary to quickly switch test points or adjust the attitude of the tester, the first cylinder 310, the second cylinder 320, the third cylinder 330, and the fourth cylinder 340 can quickly respond to the instructions of the controller and quickly complete the corresponding actions, improving the test efficiency and reducing the test time.

[0049] Please refer to again Figure 2, in some embodiments, the first cylinder 310 includes a first cylinder block 311 and a first slider 312. The first slider 312 is slidably connected to the first cylinder block 311. The first cylinder block 311 is disposed on the base 100, and the second cylinder 320 is connected to the first slider 312. Specifically, the first cylinder block 311 is stably disposed on the base 100, providing a solid support foundation for the entire displacement assembly 300. The first slider 312 slides within the first cylinder block 311 and is connected to the second cylinder 320, keeping the second cylinder 320 stable during movement, reducing shaking and deviation, ensuring the stability of the tester 500 during testing at different positions, and avoiding affecting the test results due to unstable structure. Thus, the first slider 312 is slidably connected to the first cylinder block 311, enabling the second cylinder 320 to accurately move along the first direction X under the constraint of the first cylinder block 311. In electromagnetic protection testing, this precise displacement ability can ensure that the tester 500 accurately reaches the predetermined test points, thereby obtaining more accurate test data and improving the accuracy and reliability of the test. Moreover, by adjusting the parameters of the first cylinder 310, such as the stroke length, sliding speed, etc., it can adapt to electromagnetic protection tests of different scales and requirements.

[0050] Please refer again to Figure 2, in some embodiments, the second cylinder 320 includes a second cylinder block 321 and a second slider 322. The second slider 322 is slidably connected to the second cylinder block 321. The second cylinder block 321 is connected to the first slider 312, and the third cylinder 330 is connected to the second slider 322. Specifically, by connecting the second cylinder block 321 to the first slider 312, on the basis of the stable support provided by the first cylinder 310, the structural strength of the entire displacement assembly 300 is further enhanced. The second slider 322 slides within the second cylinder block 321 and is connected to the third cylinder 330, enabling the displacement assembly 300 to remain stable during the multi-level movement process, greatly reducing the shaking and offset of the test device during the test, and providing a solid guarantee for the tester 500 to obtain accurate test results. Secondly, the simple structure of the second slider 322 and the second cylinder block 321 used in the second cylinder 320, similar to the first cylinder 310, enables the entire displacement assembly 300 to maintain a high degree of consistency and convenience in installation and maintenance, further reducing the maintenance cost and time. Thirdly, by adjusting the parameters of the second cylinder 320, such as the stroke length, sliding speed, etc., and coordinating with the parameter adjustment of the first cylinder 310, the adaptability of the test device to electromagnetic protection tests of different scales and requirements can be further expanded. In this way, in the present application, through the sliding connection between the second slider 322 and the second cylinder block 321, the third cylinder 330 can accurately move along the second direction Y under the constraint of the second cylinder block 321. Coupled with the displacement basis provided by the first cylinder 310, the tester 500 can be further positioned more accurately to fine test points, thereby obtaining more comprehensive and accurate test data to assist in in-depth analysis of the electromagnetic protection performance of the object under test 600.

[0051] Please refer to again Figure 2 , and refer to together Figure 3 , Figure 3Schematically shows the structural diagram of the third cylinder in the electromagnetic protection test device provided by the embodiment of the present application; in some embodiments, the third cylinder 330 includes a third cylinder body 332 and a turntable 333 disposed on the third cylinder body 332. The third cylinder body 332 is connected to the second slider 322, and the turntable 333 is connected to the fourth cylinder 340. Specifically, by connecting the third cylinder body 332 to the second slider 322, the movement transmitted by the first cylinder 310 and the second cylinder 320 is stably received, and at the same time, stable support is provided for the turntable 333 and the fourth cylinder 340. During the test, even if the tester 500 rotates and displaces at multiple angles, the test device can still remain stable, reducing the impact of shaking or offset on the test accuracy and ensuring the reliability of the test data. Secondly, through the rotation function of the turntable 333, electromagnetic data in different directions of the object under test 600 can be obtained, so as to more comprehensively evaluate its electromagnetic protection ability, avoid detection loopholes caused by limited test angles, and realize the all-round electromagnetic protection performance detection of the object under test 600. In this way, combined with the linear displacement provided by the first cylinder 310 and the second cylinder 320, the movement mode of the tester 500 in space is more diverse, and the electromagnetic protection test of the object under test 600 can be carried out from different angles, greatly improving the flexibility of the test and meeting the requirements for multi-angle data acquisition in complex test scenarios.

[0052] Please refer to again Figure 2, in some embodiments, the fourth cylinder 340 includes a fourth cylinder block 341 and a telescopic rod 342 disposed inside the fourth cylinder block 341. The fourth cylinder block 341 is connected to the turntable 333, and one end of the telescopic rod 342 away from the third cylinder 330 is connected to the attitude adjustment assembly 400. Specifically, combining the movement functions of the first cylinder 310, the second cylinder 320, and the third cylinder 330, the telescopic movement of the telescopic rod 342 further enriches the movement dimensions of the tester 500 in space. This enables the testing device to not only perform displacement and rotation in different directions but also make precise distance adjustments in the third direction Z, allowing the tester 500 to conduct electromagnetic protection tests on the object under test 600 from more angles and positions, more comprehensively covering the test area, improving the integrity and accuracy of the test, and helping to discover the changes in the electromagnetic protection performance of the object under test 600 at different distances and positions. Secondly, the fourth cylinder 340 can flexibly adjust the extended length of the telescopic rod 342 according to the distance of the test points in the object under test 600, enabling the testing device to adapt to different types and specifications of objects under test 600. In addition, the rapid telescopic function of the telescopic rod 342 can adjust the position of the tester 500 in a short time without the need for manual and cumbersome distance adjustment operations. When conducting tests with multiple test points, it can greatly save the test time, improve the test efficiency, and make the entire electromagnetic protection test process more efficient and smooth, especially suitable for large-scale and multi-test-point test tasks. Thus, through the telescopic movement of the telescopic rod 342 inside the fourth cylinder block 341, the present application can precisely adjust the attitude adjustment assembly 400 and the distance between the tester 500 and the object under test 600. In electromagnetic protection tests, different test items and objects under test 600 may require the tester 500 to collect data at different distances and different test points. This precise distance adjustment function can ensure that the tester 500 is in the best test position, thereby obtaining more accurate and reliable test data.

[0053] In some embodiments, the first cylinder 310 and the second cylinder 320 are mechanical guide rodless cylinders, the third cylinder 330 is a gear rotary cylinder, and the fourth cylinder 340 is a telescopic cylinder. Specifically, a mechanical guide rodless cylinder does not have external components such as a piston rod and a cylinder head of a traditional cylinder, and has a compact structure. Installed in the device, it can effectively save space and make the layout of the entire displacement assembly more concise and reasonable. In addition, the mechanical guide rodless cylinder can provide high-precision linear guidance, ensuring good straightness and stability of the first cylinder 310 and the second cylinder 320 during movement, so that the components connected thereto move more precisely in the first direction X and the second direction Y, which is beneficial to improving the accuracy and reliability of the test. The gear rotary cylinder can achieve precise angle control. Through the internal gear transmission mechanism, the linear motion of the cylinder can be converted into precise rotary motion, enabling the components connected thereto to rotate at a set angle, providing accurate rotary positioning for the tester 500, and meeting the requirements for different angle tests in electromagnetic protection tests. The main function of the telescopic cylinder is to achieve simple and direct telescopic motion, and it can provide stable linear telescopic power for the attitude adjustment assembly 400, enabling the tester to make precise position adjustments in the third direction Z, meeting the adjustment requirements for the height or distance of the tester in different test scenarios.

[0054] Please refer again to Figure 2, in some embodiments, the attitude adjustment assembly 400 includes a first swing cylinder 410 and a second swing cylinder 420; the first swing cylinder 410 is disposed at one end of the fourth cylinder 340 away from the third cylinder 330, and the bending angle of the first swing cylinder 410 is 0 to 90°; the second swing cylinder 420 is disposed at one end of the first swing cylinder 410 away from the fourth cylinder 340, the tester 500 is disposed at one end of the second swing cylinder 420 away from the first swing cylinder 410, and the bending angle of the second swing cylinder 420 is 0 to 90°. Specifically, the bending angles of the first swing cylinder 410 and the second swing cylinder 420 can be any one of 0°, 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90° or the range value between any two of them. In this way, each of the first swing cylinder 410 and the second swing cylinder 420 has the ability to adjust the bending angle of 0 to 90°, and the angle can be flexibly selected, so that the tester 500 can detect the object to be tested 600 from multiple different tilt angles, greatly expanding the test angle range. In actual electromagnetic protection tests, the test point positions of the object to be tested 600 may be different. Through the multi-angle adjustment function of the attitude adjustment assembly 400 in this application, the tester 500 can flexibly adjust its own attitude according to the specific test point, and obtain electromagnetic protection data more accurately. In addition, the first swing cylinder 410 and the second swing cylinder 420 can be automatically controlled by a controller. The operator only needs to set the required bending angle on the controller, and the first swing cylinder 410 and the second swing cylinder 420 can automatically adjust to the corresponding positions, reducing the complexity and error of manual operation, and improving the convenience and efficiency of the test device.

[0055] In some embodiments, the electromagnetic protection test device further includes a plurality of solenoid valves (not shown in the figure), and at least one solenoid valve is provided for each of the first cylinder 310, the second cylinder 320, the third cylinder 330, the fourth cylinder 340, the first swing cylinder 410, and the second swing cylinder 420. The solenoid valve is electrically connected to the controller. Specifically, the controller can independently control each cylinder through the solenoid valve, and can accurately adjust the motion parameters of each cylinder according to the test requirements, such as motion speed, displacement distance, rotation angle, swing amplitude, etc., so as to realize the precise adjustment of the tester 500 in terms of spatial position and attitude, greatly improving the accuracy and reliability of the test. At the same time, through the solenoid valve, the controller can also realize the synchronous coordinated movement of multiple cylinders to complete specific test actions in complex test scenarios. For example, when adjusting the tester 500 to a certain precise test position and attitude, it may be necessary for the first cylinder 310, the second cylinder 320, and the fourth cylinder 340 to move simultaneously in a preset manner, while the first swing cylinder 410 and the second swing cylinder 420 perform corresponding angle adjustments. The solenoid valve can ensure that each cylinder acts in coordination according to an accurate time and sequence, ensuring the smooth progress of the test process. In addition, the solenoid valve has the characteristic of fast response speed and can quickly open or close after receiving the instruction from the controller, thereby quickly controlling the movement of the cylinder, enabling the cylinder to react quickly, reducing the waiting time during the test process, improving the test efficiency, and being particularly suitable for scenarios that require a large number of rapid tests. Again, in combination with the controller, the solenoid valve can realize the automation of the test process. Just preset the test program and parameters in the controller, and the solenoid valve can automatically control the actions of each cylinder according to the program to complete a series of complex test steps without frequent manual operation, further improving the test efficiency and the consistency of the test results.

[0056] Optionally, in the embodiments of the present application, the model of the first cylinder 310 is OSP-P63-2000, the model of the second cylinder 320 is OSP-P40-1, the model of the third cylinder 330 is CDRA1BS50*180°, the model of the fourth cylinder 340 is SC32-1200, and the models of both the first swing cylinder 410 and the second swing cylinder 420 are HC3240L. The solenoid valve uses a three-position five-way double-electric-control solenoid valve, and the model of the solenoid valve is 4V220-08. Each of the first cylinder 310, the second cylinder 320, the third cylinder 330, the fourth cylinder 340, the first swing cylinder 410, and the second swing cylinder 420 is connected to its respective air pump through a separate air pipe, and the solenoid valve is arranged on the corresponding air pipe. The coil of the solenoid valve is electrically connected to the controller, and the controller is a PLC controller with the model YTRC-08.

[0057] Please refer to again Figure 1, in some embodiments, the electromagnetic protection test device further includes a counterweight 200 disposed on the base 100. Specifically, during the test, the test device may be affected by various external forces, such as the reaction force generated by the movement of the cylinder, the vibration of the surrounding environment, etc. The counterweight 200 increases the weight of the base 100, thereby increasing the overall inertia of the device. When subjected to external interference, the greater inertia makes the test device less likely to shake or displace, ensuring that the tester 500 maintains a stable position and posture during the test, and thus improving the accuracy and reliability of the test results. Secondly, setting the counterweight 200 on the base 100 effectively reduces the center of gravity of the device, further improving the balance performance of the test device and making it more stable during operation. Especially when performing some tests that require high-precision positioning and attitude adjustment, a stable device can better ensure that the tester 500 operates according to the preset parameters, reducing errors caused by device shaking. In addition, to further improve the applicability of the test device, pulleys can be provided at the bottom of the base 100 to facilitate the movement of the test device.

[0058] In some embodiments, the electromagnetic protection test device further includes a key device (not shown in the figure), which is electrically connected to the controller. Specifically, the key device provides an intuitive and simple manual control method. During the test, by pressing the corresponding keys, instructions can be directly sent to the controller to quickly adjust the actions of the displacement component 300, the attitude adjustment component 400, etc., such as controlling the telescoping and swinging of each cylinder, or adjusting the position and angle of the tester 500. Compared with complex programming or automated operations, key operations are simpler and easier to understand, reducing the technical threshold for operators and improving the flexibility of operation. In addition, through the key device, the test process can be quickly started or paused. When a new test item needs to be started or the test needs to be interrupted temporarily, just press the corresponding key to start and pause the test device, saving time and improving the test efficiency.

In actual tests, there are often multiple components to be tested, and the components to be tested have multiple test points. Using the test device of the present application, automated testing can be carried out, enabling the test personnel to more attentively observe the test phenomena and record and store the test data.

[0062] Place the test device parallel to the test table 700. A low dielectric constant plate 710 is provided on the test table 700. The object to be tested 600 is placed on the low dielectric constant plate 710.

The object to be tested 600 includes a to-be-tested wire harness 610 and a to-be-tested sample 620 connected to each other. The tester 500 is close to the side to be tested of the target sample and the test points on the target sample. Since the appearance sizes of different objects to be tested 600 are different, it is necessary to manually control the tester 500 to reach each test point first.

[0063] During this process, the working order of the test device is: the solenoid valve of the first cylinder 310 is energized, the first slider 312 slides, and the second cylinder 320 moves to a suitable height.

According to the test point, it is judged whether the first swing cylinder 410 and the second swing cylinder 420 need to be operated. If the tester 500 is not aligned with the test point, the first swing cylinder 410 and the second swing cylinder 420 need to be operated, and the solenoid valves of the first swing cylinder 410 and the second swing cylinder 420 are energized, and the first swing cylinder 410 and the second swing cylinder 420 are each folded to the angle at which the tester 500 is perpendicular to the test point. Determine whether the third cylinder 330 needs to be actuated based on the test point. If the tester 500 is not aligned with the test point, the third cylinder 330 needs to be actuated. The solenoid valve of the third cylinder 330 is energized and the fourth cylinder 340 is rotated to a suitable angle.

[0064] Record the arrival time T of the test device at each test point 1 , T 2 , T 3 , ..., T n , the reset time of the test device is the same as the arrival time of the tester 500, and the timer y corresponding to the controller 1 The countdown time is set to T 1 , timer y 2 The countdown time is set to T 2 , timer y 3 To timer y n The same settings are made in sequence. The time that the probe of the tester 500 stays at each test point is T stop , the controller controls the corresponding timer to be set to y s After the test device is reset, the counter is incremented by 1, and a complete test is a round of testing from the first test point to the completion of testing all test points.

[0065] Finally, the test is repeated until all the objects 600 to be tested have completed the test.
