Description

Technical Field

[0001] This utility model relates to the field of radar signal technology, specifically to a radar vehicle headlight detection 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.

[0003] However, in existing technologies, the performance testing of vehicle lights and radar systems is usually conducted independently on each radar chip, requiring dedicated testing sites and rooms for evaluation, lacking a comprehensive assessment of the finished product's performance parameters. In practical use, the operating environment of vehicle lights may interfere with radar signals, leading to a decrease in detection accuracy; simultaneously, extreme environmental conditions (such as rain, snow, and fog) may further affect the performance of vehicle lights and radar. Furthermore, existing testing methods often fail to accurately detect product performance, making it difficult to comprehensively evaluate the reliability and durability of vehicle light and radar systems. Currently, radar vehicle lights are all manufactured by radar chip manufacturers without undergoing systematic testing after leaving the factory, and systematic radar testing shielding boxes are expensive and far from commercially available. Without the assistance of testing equipment, cyclists can only rely on experience and cautious riding to avoid other vehicles, posing a high risk to cycling safety.

[0004] Therefore, there is an urgent need to develop a miniaturized, low-cost radar headlight detection device. Utility Model Content

[0038] Example

[0039] A radar vehicle headlight detection device, such as Figure 1 As shown, the system includes a first housing 16, a second housing 30, a window 25, a shielding mechanism, a corner reflector 19, and an antenna 23. The first housing 16 and the second housing 30 share the same surface for connection. 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 of 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 antenna 23 is located inside the first housing 16 and extends out of the first housing 16 to connect to external testing equipment. The radar product under test 5 is connected to the external testing equipment via the antenna 23.

[0040] The device constructs a closed electromagnetic shielding environment through a layered design of upper and lower enclosures. 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-world scenario, 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-world scenario. The external testing equipment uses a test tablet computer with a built-in test app, which can calculate the signal-to-noise ratio (SNR) by comparing the noise (without shielding) and signal (without shielding) strengths using algorithms.

[0041] Specifically, the blocking mechanism includes a blocking block 20, a blocking cylinder 26, and a slide rail. The blocking cylinder 26 drives the blocking block 20 to move along the slide rail to open or close the window 25.

[0042] like Figure 3-4As shown: In a preferred embodiment, the second housing 30 is equipped with a mounting bracket 29 and the corner reflector 19. The surface of the mounting bracket 29 is provided with 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.

[0043] Furthermore, the first housing 16 contains a carrier 18, which includes a fixture fixing base 1 and a fixture upper cover plate 2. The fixture fixing base 1 has a positioning groove 14 that matches the radar product 5 under test. The lower surface of the fixture upper cover plate 2 has a pressure block 11, which is connected to the fixture upper cover plate 2 by four spring pins 4. The four spring pins 4 are evenly distributed around the upper surface of the pressure block 11. The pressure block 11 and the spring pins 4 are made of plastic steel. Through the combined design of the fixture fixing base 1 and the fixture upper cover plate 2, the carrier 18 can accurately fix the radar product 5 under test. The pressure block 11 is connected to the upper cover plate by the spring pins 4, providing uniform elastic pressure, which can effectively fix the product and avoid surface damage caused by hard contact. The four spring pins 4 are evenly distributed around the pressure block 11 to ensure uniform pressure distribution and avoid product deformation or damage caused by local stress concentration. The spring pin 4 and the pressure block 11 are made of plastic steel, which combines elasticity and wear resistance. They can provide stable fixing force and maintain long-term durability in high-frequency testing.

[0044] In a preferred embodiment, one end of the fixture fixing base 1 is hinged to one end of the fixture upper cover plate 2, and the other end is connected to the other end of the fixture upper cover plate 2 via a detachable snap-fit ​​assembly 12. The snap-fit ​​assembly 12 includes a snap-fit ​​12 and a slot 13 located on the fixture fixing base 1. The snap-fit ​​12 and the slot 13 are locked or unlocked through elastic deformation. The snap-fit ​​12 is located on the lower surface of one end of the fixture upper cover plate 2, and a locking handle 3 is provided on the corresponding upper surface. The combination of the hinge and the snap-fit ​​assembly 12 makes the opening and closing of the cover plate simple, significantly improving installation efficiency. The snap-fit ​​assembly 12 achieves locking and unlocking through elastic deformation, which is simple to operate and highly reliable. Furthermore, pressure can be easily applied through the locking handle 3 to lock or unlock.

[0045] like Figure 5-7As shown, in a preferred embodiment, a sliding drive mechanism is further included. This mechanism comprises a slide plate 6, a carrier 18 slide rail 7, and a carrier 18 cylinder 8. The carrier 18 cylinder 8 drives the slide plate 6 to move along the carrier 18 slide rail 7. The carrier 18 is fixed on the slide plate 6. There are two carrier 18 slide rails 7, symmetrically and parallelly arranged. Each carrier 18 slide rail 7 has a V-shaped groove on its inward-facing surface. The slide plate 6 has sliders at both ends that match the V-shaped grooves. These sliders are embedded in the V-shaped grooves, allowing the slide plate 6 to slide smoothly against the carrier 18 slide rail 7. This design of double V-shaped slide rails and sliders ensures high-precision positioning of the slide plate 6 during movement. The sliding connection between the slide plate 6 and the V-shaped slide rails at both ends via sliders eliminates the possibility of horizontal offset, ensuring that the carrier 18 maintains precise alignment during entry and exit, thus improving the reliability of the test results.

[0046] like Figure 8 As shown, in a preferred embodiment, the sliding drive mechanism is provided on the upper surface of the bottom plate of the first housing 16. A carrier 18 is provided on the upper surface of one end of the slide plate 6, and a door panel 9 is vertically connected to the other end. One side panel of the housing has an opening 15 that matches the shape of the door panel 9. The door panel 9 is driven to move along the slide rail 7 of the carrier 18 by a cylinder 8, thus opening or closing the opening 15. The door panel 9 is provided with a drawer handle. The door panel 9 is vertically connected to the slide plate 6, so that the door panel 9 opens and closes synchronously when the carrier 18 moves. The drawer handle facilitates operation, and the door panel 9 cooperates with the opening 15 of the housing to ensure a sealed testing environment. The inner wall is lined with absorbing sponge to further prevent external electromagnetic interference.

[0047] like Figure 2 As shown, in a preferred embodiment, the outer surface of the first housing 16 is provided with a storage area 24 for external testing equipment, and the second housing 30 is provided with a pressure gauge 21, a vacuum valve 22, and a control board 31. The control board 31 controls the cylinder 8 of the carrier 18 to drive the carrier 18 to move along the slide rail 7 of the carrier 18, and the control board 31 also controls the shielding cylinder 26 to drive the shielding block 20 to move along the slide rail. The design of the pressure gauge 21, vacuum valve 22, and control board 31 realizes the automated control of the shielding mechanism and the carrier 18. Closed-loop control is formed through air pressure feedback to ensure the accuracy and stability of the movement of the shielding block 20 and the carrier 18.

[0048] The working process of this utility model is as follows:

[0049] The operator activates the sliding drive mechanism via control panel 31. Cylinder 8 of the carrier 18 drives the slide plate 6 to move along the V-shaped slide rail, moving the carrier 18 out of the first housing 16. The door panel 9 moves synchronously with the slide plate 6, opening the opening 15 and placing the radar headlight into the positioning groove 14, ensuring a perfect match. The upper cover plate 2 of the fixture is then closed, and the latch assembly 12 automatically locks through elastic deformation. The sliding drive mechanism is then activated again via control panel 31, and the carrier 18 smoothly enters the first housing 16. The door panel 9 moves synchronously with the slide plate 6, closing the opening 15 and ensuring the sealing of the testing environment.

[0050] Subsequently, the operator activates the shielding mechanism via control panel 31. Shielding cylinder 26 drives shielding block 20 to move along the slide rail, closing window 25 to block external signals. At this time, the radar headlights only receive ambient noise data. Next, shielding block 20 moves away, window 25 opens, and the radar signal emitted by the headlights is reflected by corner reflector 19, with the echo signal captured by the headlights. The signal received by the radar headlights is transmitted via antenna 23 to external testing equipment. The external testing equipment is a test tablet computer with a built-in test app. This app uses algorithms to compare noise (when shielded) and signal (when unshielded) strengths to calculate the signal-to-noise ratio (SNR). This allows for the evaluation of the radar headlights' core performance indicators, such as detection sensitivity and anti-interference capability.

[0051] During testing, the height of the corner reflector 19 can be adjusted via the mounting bracket 29 to simulate reflection scenarios at different distances. After testing, the door panel 9 is opened, allowing operators to quickly replace the next product under test.
