Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing systems, specifically a radar aperture testing system. Background Technology

[0002] In the process of automobile manufacturing and intelligent upgrading, sensors such as millimeter-wave radar and lidar need to be fixed through pre-set mounting holes on the vehicle body (i.e., "radar holes"). Their position (three-dimensional coordinates) and angular parameters (tilt angle, azimuth angle) directly affect the sensor's detection performance and the overall vehicle's functional safety. However, due to vehicle model iterations, multi-brand compatibility, and differences in sensor types, the design parameters of radar holes are highly non-standardized. This leads to problems in the testing process, such as insufficient compatibility of testing equipment due to the diversity of radar hole parameters, and low accuracy of automated identification of non-standard hole positions and angles. In particular, existing mechanical positioning methods have limitations.

[0003] 1. The mechanical positioning method uses probe contact measurement, which is prone to probe jamming or collision damage due to deviation in the hole position angle;

[0004] 2. When the probe of the mechanical positioning method causes damage to the orifice, it is often not very obvious and therefore difficult to detect. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0032] Please see Figures 1 to 6 This utility model provides a technical solution: a radar hole detection system, including a base 1, a lifting frame 2, a transverse frame 3, and a radar hole detection component 4. The bottom of the lifting frame 2 is fixedly installed on the base 1, the transverse frame 3 is installed on the lifting frame 2, and the radar hole detection component 4 is installed on the transverse frame 3. The radar hole detection component 4, driven by the lifting frame 2 and the transverse frame 3, can move up and down and left and right, so that the radar hole detection component 4 can meet the radar hole detection of different models and types of vehicles.

[0033] The lifting frame 2 includes a hydraulic cylinder 21 and a guide column 22. The output shaft of the hydraulic cylinder 21 is connected to the connecting frame 23. The connecting frame 23 is connected to the guide column 22 through a guide wheel 24. The hydraulic cylinder 21 is used to drive the connecting frame 23 to move vertically along the guide column 22.

[0034] The transverse frame 3 includes a connecting beam 31 and a mounting plate 32. One end of the connecting beam 31 is connected to the connecting frame 23, and the other end is connected to the mounting plate 32. A transverse rod 33 is provided below the mounting plate 32. The transverse rod 33 can drive the mounting plate 32 to move laterally. The transverse rod 33 is used to drive the mounting plate 32 to move laterally.

[0035] The radar hole detection assembly 4 includes a detection rod 41. The root of the detection rod 41 is detachably connected to the output shaft of the electric actuator 42. The detection rod 41 is used to insert into the radar hole to detect the diameter and depth of the radar hole. At the same time, the detachable connection means that the detection rod 41 can be replaced when needed to meet the detection requirements of radar holes with different diameters.

[0036] In this embodiment, the base 1 is provided with a fixing seat 11. The fixing seat 11 is used to fix and install the hydraulic cylinder 21, and also to facilitate the base to be placed on the ground and provide support.

[0037] In this embodiment, the bottom of the hydraulic cylinder 21 is fixedly connected to the fixed base 11.

[0038] In this embodiment, the connecting frame 23 includes a crossbeam 231 and a roller frame 232. Both ends of the crossbeam 231 are provided with roller frames 232. The roller frames 232 are used to install guide wheels 24. The guide wheels 24 can reduce friction and increase the service life of the guide column 22.

[0039] In this embodiment, the transverse rod 33 is a threaded rod, and both ends of the transverse rod 33 are rotatably installed in the rod frame 331. One end of the transverse rod 33 is equipped with a motor, and the rotation of the transverse rod 33 driven by the motor drives the mounting plate 32 to move laterally.

[0040] In this embodiment, a guide groove rod 35 is provided above the rod frame 331. The guide groove rod 35 has a T-shaped guide groove inside. The guide groove is connected to the moving block 36 through a T-shaped block. The moving block 36 is installed on the transverse rod 33 through a threaded sleeve. The connection between the guide groove and the T-shaped block can both limit the movement of the moving block 36 and prevent the moving block 36 from rotating on the transverse rod 33, and also guide the lateral movement of the moving block 33.

[0041] In this embodiment, the detection rod 41 includes a guide head 411, a light-transmitting shell 412, and an inner core 413. The light-transmitting shell 412 is detachably sleeved on the inner core 413. The guide head 411 is installed on the top of the inner core 413. The inner core 413 is provided with a light strip 414. The guide head 411 provides guidance for the insertion of the detection rod 41 into the radar hole. The outer diameter of the light-transmitting shell 412 matches the aperture of the radar hole for detecting the aperture. The light strip 414 emits strong light, which can determine whether there is a gap between the detection rod 41 and the radar hole by checking for light leakage after the detection rod 41 is inserted into the radar hole, and can also observe whether there is any damage to the opening of the radar hole by supplementing the light.

[0042] In this embodiment, the electric push rod 42 is fixedly mounted on the electric turntable 44 below, and the electric turntable 44 is fixedly mounted on the mounting plate 32. By rotating the electric turntable 44, the detection rod 41 is driven to complete the rotation at any angle, which satisfies the detection of radar holes with different orientation angles.

[0043] Working principle: First, the vehicle component with radar hole to be tested is fixedly placed. Based on the position of the radar hole, the detection rod 41 is positioned at the radar hole by adjusting the lifting frame 2 and the transverse frame 3. If the radar hole has different angles, the electric turntable 44 is used to drive the detection rod to be inserted into the detection hole.

[0044] Based on the above, the lifting frame and the transverse frame of this utility model, along with the electric push rod, enable the detection rod to move in the x, y, and z axes, satisfying the detection of radar holes in different positions on different vehicle models. The electric turntable, which can be manually controlled to rotate, allows the detection rod to rotate at any angle, enabling the detection rod to be inserted into radar holes facing different directions for direct insertion detection. The light strip located on the inner core of this utility model provides sufficient illumination, facilitating observation and timely results when minor hole damage occurs during detection.

[0045] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
