The operating frequency of automotive radar is generally 24GHz or 77GHz, and the working principle is mostly based on the Doppler effect. At present, although the best installation position of the automotive radar is expected in the early stage of design, the appearance of the car is often changed in the mud mold stage, so it is necessary to move the radar to adapt to the new design or test the impact of different positions on performance.

[0003] When conducting vehicle model tests, engineers mainly conduct multiple tests on the vehicle model under test track conditions to fine-tune the radar position and angle and observe its performance in different driving conditions.

If necessary, a telescopic rod and a universal joint are set to adjust the radar's posture to meet the radar's adjustment to the angle and position required for the test, thereby simulating the perception of the vehicle radar, so as to verify whether the vehicle radar has omissions and feedback interference at a specific position. If there are several parallel selection positions for the radar, repetitive tests are usually carried out and more application scenarios are tested, such as simulating special situations such as vehicle jitter and object reflection characteristics. Although the telescopic rod and universal joint have high adaptability, it is not easy to reset and adjust to the same position during repeated tests, which may affect the accuracy of the test results; therefore, it is worth studying how to better optimize the adjustment of the vehicle radar in the existing vehicle radar test process.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] refer to Figure 1 As shown, one embodiment of the utility model is a calibration device based on intelligent networked car radar testing, including a carrier 1, an angle adjuster 2 and a travel seat 3, wherein the carrier 1 is used to be fixed on a car model frame and form a test point reference. Among them, the carrier 1, as a reference point, provides a radar installation reference point for the entire test process, so that during the repeatability test process, a relative position can be referenced. Through the fixed reference point, it can be ensured that the position, angle and other conditions of the radar are kept as consistent as possible during each test. Reducing the risk of inconsistent data from multiple tests is beneficial to the repeated setting of the radar position, which is beneficial to the accuracy and repeatability of the data. The reference point allows the radar to have a relative relationship with the car model frame, which is beneficial to ensuring the consistency of the test conditions and reducing the risk of deviation, especially when conducting long-term performance evaluations and multiple measurements.

[0027] The angle adjuster 2 is fixed on the carrier 1, and a travel plate 4 is installed on the movable end of the angle adjuster 2, wherein the angle adjuster 2 is fixed on the carrier 1 and stably supports the travel plate 4, and the central axis of the travel plate 4 is in the same plane as the carrier 1.

[0028] The travel plate 4 is provided with a first guide rail 401, and the cross-sectional profile of the travel seat 3 is consistent with the cross-sectional profile of the inner cavity of the first guide rail 401. In order to ensure the smooth sliding of the travel seat 3 in the first guide rail 401, the outer wall of the travel seat 3 and the inner wall of the first guide rail 401 are relatively smooth, thereby reducing the friction between the first guide rail 401 and the travel seat 3, so that the travel seat 3 moves smoothly and accurately in the guide rail, effectively reducing friction and mechanical wear.

[0029] The travel seat 3 is slidably arranged in the first guide rail 401 of the travel plate 4, so that the moving path of the travel seat 3 in the first guide rail 401 is determined. The travel seat 3 moves precisely along the first guide rail 401, so that the test position of the travel seat 3 can be constrained and limited.

[0030] In order to better control the movement of the travel seat 3, a lead screw 402 is provided in the first guide rail 401, and the travel seat 3 is sleeved on the lead screw 402, and the lead screw 402 rotates to drive the travel seat 3 to move in the first guide rail 401; wherein, bearing seats 901 are provided at both ends of the first guide rail 401, wherein the bearing seats 901 are fixed to the inner wall of the first guide rail 401, and the lead screw 402 is fixed to the travel plate 4 through the bearing seats 901, so that the lead screw 402 can rotate on the travel plate 4, thereby driving the travel seat 3 in the first guide rail 401 to move. wherein, the central axis of the bearing of the bearing seat 901 overlaps with the central axis of the lead screw 402, and a handle 9 is provided on the side of the travel plate 4 away from the angle adjuster 2, and the lead screw 402 passes through the travel plate 4 to connect the handle 9, and the handle 9 drives the lead screw 402 to rotate.

[0031] For reference, a driving gear can be welded to the center axis of the handle 9, and the driving gear is used for an external reduction motor. A gear meshing with the driving gear is arranged on the output shaft of the reduction motor, so that the handle 9 can be driven by the reduction motor under the drive gear.

[0032] When considering adjustment, it is necessary to provide a stable and flexible platform to install and fix the car radar. The travel seat 3 is provided with a bearing plate 5, and one side of the travel plate 4 is provided with a clamp 6, which is installed on the bearing plate 5; the clamp 6 is used to install the car radar. The clamp 6 is installed on the bearing plate 5 outside the travel plate 4, so that the fixation of the car radar will not be directly affected by the travel plate 4. Under the premise of ensuring the stability of the travel plate 4, the vibration during the test or the risk of collision during movement can be reduced.

[0033] Among them, the side wall of the first guide rail 401 is provided with an opening for the carrier plate 5 to pass through, so as to facilitate the carrier plate 5 to pass through it. The above-mentioned angle adjuster 2 is used to drive the travel plate 4 to rotate in the horizontal direction and form a test angle with the carrier 1, and the travel seat 3 is used to drive the clamper 6 to move to the test position on the first guide rail 401, so that the carrier plate 5 and the clamper 6 and radar installed thereon can move along the predetermined path on the first guide rail 401 to the required test position, thereby obtaining higher test flexibility.

[0034] Based on the above embodiment, in order to control the angle state of the angle adjuster 2, refer to Figure 2 and Figure 3As shown, another embodiment of the utility model is that the angle adjuster 2 includes a reference seat 201 and a pendulum 202, the reference seat 201 is fixed on the carrier 1, wherein the reference seat 201 and the carrier 1 are in constant position, a first rotating shaft 203 is provided on the reference seat 201, the relative position of the first rotating shaft 203 and the reference seat 201 is unchanged, and the pendulum 202 is connected to the first rotating shaft 203, and the pendulum 202 rotates on the first rotating shaft 203. Through the design of the first rotating shaft 203, the pendulum 202 is limited by the first rotating shaft 203 and rotates around the first rotating shaft 203. The pendulum 202 is connected to the stroke plate 4, and the pendulum 202 and the stroke plate 4 are on the same straight line. When the pendulum 202 forms an angle with the reference seat 201, the stroke plate 4 and the carrier 1 also form an angle.

[0035] For reference, the reference seat 201 adopts a concave metal block structure, and one end of the reference seat 201 is in contact with the outer wall of the carrier 1. If necessary, the connection between the reference seat 201 and the carrier 1 can be welded or bolted, so as to ensure that the angle adjuster has good stability after being fixed. At the same time, in order for the reference seat 201 to better bear the load, the reference seat 201 adopts a metal material with sufficient hardness, such as an alloy material or a polycarbon material, to ensure that the mechanical strength of the reference seat 201 meets the support requirements.

[0036] Furthermore, in order to better limit the adjustment range of the pendulum column 202, an arc groove 204 is provided at the end of the above-mentioned reference seat 201, and the above-mentioned first rotating shaft 203 is vertically installed in the arc groove 204. The arc groove 204 is a fan-shaped structure. The above-mentioned pendulum column 202 is inserted into the arc groove 204 to connect the first rotating shaft 203. The inner walls at both ends of the above-mentioned arc groove 204 are used to resist the pendulum column 202, and the rotation angle of the pendulum column 202 is limited between the inner walls at both ends of the arc groove 204, so that the physical boundary of the arc groove 204 corresponds to the rotation angle of the pendulum column 202. The arc groove 204 at the end of the reference seat 201 is mainly used to limit the movement range of the pendulum 202. Specifically, the first rotating shaft 203 is vertically installed in the arc groove 204, and the pendulum 202 extends into the arc groove 204. The rotation of the pendulum 202 is limited by the curvature of the inner wall of the arc groove 204. For example, if the angle between the two ends of the arc groove 204 is 90 degrees, the movement range of the pendulum 202 is limited to 90 degrees. The physical limitation of the rotation range of the pendulum 202 by the arc groove 204 is conducive to better setting the detection angle of the radar. The rotation range setting of the pendulum 202 can also reduce operational errors and avoid equipment impact caused by excessive rotation.

[0037] For reference, the inner cavity height of the arc groove 204 is consistent with the outer wall height of the pendulum column 202. The inner wall of the arc groove 204 is in smooth contact with the upper surface or the lower surface of the pendulum column 202, which reduces the friction coefficient on the one hand, and reduces the risk of swinging and vibration of the pendulum column 202 during rotation on the other hand, which helps to maintain the stability of the entire device, thereby improving the reliability and accuracy of the test.

[0038] Furthermore, in order to better determine the angle state of the pendulum column 202 and facilitate the accuracy of the angle adjustment during the secondary repeated test, a scale is provided on the upper end of the reference seat 201, wherein the scale on the reference seat 201 is distributed on the upper end of the reference seat 201 with the first rotating shaft 203 as the center, thereby providing a user with an intuitive method to read the angle state between the pendulum column 202 and the reference seat 201. An extension column 205 is provided on the upper end of the pendulum column 202, the height of the top end of the extension column 205 is greater than the height of the upper end of the reference seat 201, and a pointer 206 pointing to the scale is provided on the top of the extension column 205.

[0039] For reference, the pointer 206 on the top of the extension column 205 is made of a material with a certain hardness and toughness, such as a manganese steel sheet. The extension column 205 is vertically arranged, and the pointer 206 is raised to a sufficiently high position by the extension column 205, so that the pointer 206 is away from the reference seat 201, and at the same time, the pointer 206 is conducive to pointing to the scale of the reference seat 201.

[0040] When adjusting the angle, the pointer 206 and the extension column 205 move synchronously with the pendulum column 202, and there is a gap between the pendulum column 202 and the reference seat 201, thereby ensuring that the pointer 206 does not touch the reference seat 201 when moving, which is beneficial to the stability and continuity of the reading. In particular, when performing repeated tests, the specific angle set before can be quickly found through the scale and the pointer 206, ensuring the consistency of the test conditions, thereby improving the comparability of the data and the effectiveness of the test.

[0041] Based on the above embodiments, reference Figure 2 and Figure 3As shown, another embodiment of the utility model is that, in order to adjust the rotation angle of the clamp 6, a bearing 7 is provided between the pendulum column 202 and the stroke plate 4, wherein the bearing 7 can be an existing product, and the inner ring and the outer ring of the bearing 7 are respectively connected to the stroke plate 4 and the pendulum column 202, and the stroke plate 4 rotates on the pendulum column 202, so that the stroke plate 4 and the pendulum column 202 can rotate relative to each other. The bearing 7 allows the stroke plate 4 to rotate smoothly on the pendulum column 202, and in order to position at a specific rotation angle, a mounting block 701 is provided at the upper end of the stroke plate 4, and a limiting circular plate 702 is provided at the end of the pendulum column 202, and a limiting screw hole is provided on the mounting block 701, and a limiting hole 703 corresponding to the limiting screw hole is provided on the limiting circular plate 702, wherein the limiting screw hole and the limiting hole 703 have the same aperture, the limiting screw hole is a through hole, and the limiting hole 703 is a countersunk hole. Through multiple limiting holes 703 distributed around the bearing axis on the limiting circular plate 702, the limiting holes 703 cooperate with the limiting screw holes on the mounting block 701. When fixing is required, the limiting pin 704 can be inserted into the limiting hole 703 and the limiting screw hole, so that the limiting pin 704 limits the relative rotation of the stroke plate 4 and the limiting circular plate 702, ensuring that the stroke plate 4 will not rotate relative to the pendulum column 202, so that the limiting circular plate 702 cooperates with the mounting block 701 to fix the stroke plate 4 at a specific angular position.

[0042] There are multiple limiting holes 703, and through the setting of multiple limiting holes, multiple locking points of corresponding angles are obtained on the limiting circular plate 702, wherein the limiting holes 703 are distributed around the limiting circular plate 702 with the axis of the bearing 7 as the center, so that the position of the limiting holes 703 corresponds to the moving path of the mounting block 701, and the limiting holes 703 are used to cooperate with the limiting screw holes to insert the limiting pins 704, which greatly improves the convenience and repeatability of the operation. That is, on the basis of the bearing 7 being set between the pendulum column 202 and the stroke plate 4 to realize rotation, the limiting screw holes and the limiting pins 704 on the limiting circular plate 702 and the mounting block 701 are used to lock the rotation, so as to adjust the vertical rotation angle of the stroke plate 4 and the pendulum column 202, so as to facilitate the adjustment of the rotation angle of the clamp 6.

[0043] Based on the above embodiments, reference Figure 1 and Figure 5As shown, another embodiment of the utility model is that in order to adjust the position of the clamp 6 relative to the stroke plate 4, the clamp 6 includes a support rod 601, which is vertically arranged on the bearing plate 5. The support rod 601 is arranged on the bearing plate 5, so that the support rod 601 serves as a bearing structure of the vehicle-mounted radar, avoiding the vehicle-mounted radar from contacting the stroke plate 4 during the position adjustment process. At the same time, the bearing plate 5 serves as a reference platform. If necessary, the existing simple level can be installed on the bearing plate 5. The simple level is mainly to place a liquid in a transparent pipe, and bubbles are left in the pipe. When the liquid is stable, the bubble will naturally be in the center of the pipe. If the object is not in a horizontal state, the bubble will move to the high side, indicating the degree of inclination of the object. By arranging a simple level in the horizontal and vertical directions of the bearing plate 5, it is convenient to determine the current posture of the bearing plate 5.

[0044] Among them, the upper and lower ends of the above-mentioned support rod 601 are respectively provided with mounting ears 602, and the above-mentioned ears 602 are provided with pull-out plugs 8, and the pull-out plugs 8 on the two ears 602 are arranged oppositely. During installation, the automobile radar housing is directly connected to the ears 602 on the support rod 601 through the pull-out plugs 8. The above-mentioned pull-out plugs 8 are used to connect the housing of the automobile radar externally, wherein the pull-out plug 8 is a quick-release head of the existing radar sensor, and the pull-out plug 8 is used to be directly connected to the automobile radar housing, thereby realizing the rapid disassembly and installation of the automobile radar.

[0045] Furthermore, in order to flexibly adjust the vertical position of the automobile radar installed on the carrying plate 5, a through hole is provided on the carrying plate 5 for the support rod 601 to pass through, and the inner contour of the through hole matches the outer contour of the support rod 601, so that the support rod 601 can slide on the carrying plate 5. It is convenient for the support rod 601 to move in the vertical direction of the carrying plate 5.

[0046] In order to fix the support rod after it is moved to the position required for the test, the support rod 601 is provided with a second guide rail 603, and the support plate 5 is provided with a fixing bolt 501. The fixing bolt 501 is used to pass through the support plate 5 and extend into the bottom of the second guide rail 603, and the bottom of the second guide rail 603 is provided with an anti-skid pad that resists the fixing bolt 501. When the support rod 601 is adjusted to a suitable height, the fixing bolt 501 passes through the support plate 5 and extends into the bottom of the second guide rail 603, and the fixing bolt 501 resists the anti-skid pad at the bottom of the second guide rail 603 to limit the position of the support rod. The anti-skid pad increases the fixed friction and ensures the stability of the support rod during the test.

[0047] It should be noted that the anti-slip pad is usually limited to simulation tests in a static state. If the supporting plate 5 is required to nod, the bottom of the second guide rail 603 can also have screw holes corresponding to the fixing bolts 501, and there are multiple screw holes, and the gaps between two adjacent screw holes are the same.

[0048] Furthermore, in order to reduce the risk of deviation of the support rod 601 after being subjected to a load, a guide column 604 is provided on one side of the support rod 601, wherein the guide column 604 is parallel to the support rod 601, and a through hole is provided on the bearing plate 5 for the guide column 604 to pass through; the guide column 604 is mainly used to cooperate with the support rod 601 for vertical movement. Since the support rod 601 may be affected by force after the car radar is installed, the guide column 604 is assisted by the setting of the guide column 604, so that the support rod 601 will not deviate during the movement on the bearing plate 5, thereby preventing the guide column 604 from accidentally detaching from the bearing plate 5, and the two ends of the guide column 604 are respectively connected to the support ears 602.

[0049] Furthermore, there are more than two guide posts 604, and the guide posts 604 are distributed on both sides of the support rod 601; the side wall of the support rod 601 has an arc portion 605, and the vertical length of the arc portion 605 is the same as that of the guide post 604. The arc portion 605 mainly improves the mutual restraint between the support rod 601 and the bearing plate 5, and avoids the risk of greater shaking caused by the superposition of tolerances on both sides of the support rod 601 and the bearing plate 5 when the clearance between the support rod 601 and the bearing plate 5 is reduced due to machining tolerances in different areas.

[0050] The "one embodiment", "another embodiment", "embodiment", "preferred embodiment" and the like mentioned in this specification refer to the specific features, structures or characteristics described in conjunction with the embodiment included in at least one embodiment generally described in this application.
