Description

Technical Field

[0001] This utility model relates to the field of radar testing technology, and specifically to a radar signal acquisition device. Background Technology

[0002] With the rapid development of intelligent cycling technology, the role of cycling radar lights in cycling safety is becoming increasingly prominent. They not only provide lighting cues but also handle signal transmission and environmental interaction. As a core auxiliary technology for advanced cycling, radar systems can detect the approach of surrounding vehicles in real time, suitable for both daytime and nighttime riding. For cycling enthusiasts and competitive athletes, radar-integrated lights are essential equipment, effectively mitigating cycling risks. However, most current radar lights do not undergo systematic testing before leaving the factory, and capturing radar signals from finished products requires dedicated spaces and large-scale environmental simulation equipment, which cannot meet the needs of online testing.

[0003] Existing testing methods rely on individual radar chips for detection or expensive large shielding boxes (costing tens of thousands of yuan), making it difficult to simulate the comprehensive impact of real-world riding scenarios on finished bicycle lights. For example, the material of the light housing, the installation angle, and environmental interference may cause radar signal attenuation or misjudgment. Furthermore, existing technologies lack the ability to dynamically test the integrated state of the finished product, leading to risks of decreased detection accuracy and insufficient anti-interference capabilities for users in actual use.

[0004] Therefore, there is an urgent need to develop a miniaturized, low-cost, and efficient radar signal acquisition device. Utility Model Content

[0033] Example

[0034] A radar signal acquisition device, such as Figure 1 As shown, the device includes a first housing 16, a second housing 30, a window 25, a shielding mechanism, and a corner reflector 19. The first housing 16 and the second housing 30 share a common connecting surface. The first housing 16 is located directly below the second housing 30, and both have HS-P3 absorbing cone sponge attached to their inner walls. The window 25 is located on the connecting surface between the first housing 16 and the second housing 30. The shielding mechanism is located at the window 25 and is used to open or close the window 25. The radar signal acquisition device, through its layered design of upper and lower housings, constructs a closed electromagnetic shielding environment. The absorbing material 17 effectively absorbs stray electromagnetic waves, ensuring the purity of the test environment; the corner reflector 19 simulates the signal reflection path in a real scene, enhancing the intensity of the echo signal; the shielding mechanism controls the automatic opening and closing of the window 25, simulating dynamic signal changes in a real scene.

[0035] Specifically, such as Figure 3 As shown, the blocking mechanism includes a blocking block 20, a blocking cylinder 26, and a carrier 18 slide rail 7. The blocking cylinder 26 drives the blocking block 20 to move along the blocking slide rail 27 to open or close the window 25.

[0036] In a preferred embodiment, such as Figure 3-4As shown, the second housing 30 contains a mounting bracket 29 and the corner reflector 19. The surface of the mounting bracket 29 has a scale marking 28 for recording height. The corner reflector 19 is slidably connected to the mounting bracket 29 and its height is adjustable. The corner reflector 19 is located above the window 25, and its reflection path can pass through the window 25. The reflector's height is adjustable through its slidable connection to the mounting bracket 29, which can simulate reflection scenarios at different distances and heights, enhancing the diversity and coverage of the test. The scale marking 28 on the surface of the mounting bracket 29 provides a quantitative basis for height adjustment, making the position adjustment of the corner reflector 19 more precise and repeatable, further improving the reliability of the test results.

[0037] like Figure 5 As shown, in a preferred embodiment, the first housing 16 contains a carrier 18, and the carrier 18 contains a positioning groove 14 that matches the shape of the radar product 5 under test. One side panel of the first housing 16 has an opening 15, and a door panel 9 is provided at the opening 15 for opening or closing. The door panel 9 has a handle 10. The opening 15 on the side panel of the first housing 16 is designed to facilitate quick clamping and replacement of the product under test. The door panel 9 cooperates with the opening 15 to ensure a sealed testing environment, and the inner wall is lined with absorbing sponge to further prevent external electromagnetic interference.

[0038] like Figure 2 As shown, in a preferred embodiment, the system further includes a pressure gauge 21, a vacuum valve 22, and a control board 31. The control board 31 controls the blocking cylinder 26 to drive the blocking block 20 to move along the blocking slide rail 27. The pressure gauge 21, vacuum valve 22, and control board 31 are designed to achieve automated control of the blocking mechanism. Closed-loop control is formed through pressure feedback to ensure the accuracy and stability of the movement of the blocking block 20.

[0039] The working process of this utility model is as follows: Open the door panel 9, place the radar headlight in the positioning groove 14, and close the door panel 9 after ensuring its position is fixed. Then, the operator activates the shielding mechanism via the control panel 31. The shielding cylinder 26 drives the shielding block 20 to move along the slide rail, closing the window 25 to block external signals. At this time, the radar headlight only receives ambient noise data. Next, the shielding block 20 is moved away, the window 25 is opened, and the radar signal emitted by the radar headlight is reflected by the corner reflector 19, with the echo signal captured by the radar headlight. During the test, the height of the corner reflector 19 can be adjusted via the mounting bracket 29 to simulate reflection scenarios at different distances. After the test is completed, the door panel 9 is opened, and the operator can quickly replace the next product to be tested.
