Description

Technical Field

[0001] This utility model relates to the field of radar testing technology, specifically to an extended sliding rail type vehicle for radar vehicle light testing. Background Technology

[0002] Traditional radar test fixtures rely on manual product fixing, resulting in low clamping efficiency and susceptibility to signal drift due to operational errors. For example, the curved or irregularly shaped structure of radar headlight housings makes it difficult to perfectly match the fixing grooves, and vibrations during testing can lead to poor contact, affecting signal acquisition stability. In batch testing scenarios for radar headlights, the design of the fixture directly impacts testing efficiency and data reliability. Radar headlights (such as lidar) typically employ high-precision optical elements and special materials (such as glass or polymers) as the viewing surface to achieve accurate detection. However, the hardness and wear resistance of these materials are limited, making them prone to scratches from external forces.

[0003] Traditional test vehicles have significant drawbacks: First, their fixing methods are rigid, and surface damage is easily caused when fixing radar lights to most vehicles. Second, their positioning accuracy is insufficient. Manual placement of traditional vehicles is prone to positional deviations, such as horizontal offsets or angular tilts, causing the radar beam direction to deviate from the preset reflection path, resulting in systematic errors in the test results. Especially in multiple batches of testing, the accumulation of such errors may mask the true performance fluctuations of the product.

[0004] Therefore, there is an urgent need for a radar testing vehicle to solve the above problems. Utility Model Content

[0005] This utility model addresses the technical problems existing in the prior art by providing an extended sliding rail carrier for testing radar vehicle lights, which achieves flexible fixation and precise positioning of radar vehicle lights.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An extended sliding rail type carrier for radar vehicle light testing includes a carrier, the carrier including a fixture fixing seat and a fixture upper cover plate, the fixture fixing seat is provided with a positioning groove that matches the radar product to be tested, the lower surface of the fixture upper cover plate is provided with a pressure block, and the pressure block is connected to the fixture upper cover plate through a plurality of spring pins.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, one end of the fixture fixing base is hinged to one end of the fixture upper cover plate, and the other end is connected to the other end of the fixture upper cover plate through a detachable snap-fit ​​assembly.

[0009] Furthermore, the buckle assembly includes a buckle and a slot provided on the fixture fixing seat. The buckle and the slot are locked or unlocked by elastic deformation. The buckle is located on the lower surface of one end of the upper cover plate of the fixture, and the corresponding upper surface is provided with a locking handle.

[0010] Furthermore, there are four spring pins, which are evenly distributed around the upper surface of the pressure block. The pressure block and the spring pins are made of plastic steel.

[0011] Furthermore, it also includes a sliding drive mechanism, which includes a slide plate, a vehicle slide rail, and a vehicle cylinder. The vehicle cylinder drives the slide plate to move along the direction of the vehicle slide rail, and the vehicle is fixed on the slide plate.

[0012] Furthermore, there are two vehicle slide rails, which are symmetrically and parallelly arranged. Each vehicle slide rail has a V-shaped groove on its inner surface. The two ends of the slide plate are provided with sliders that match the V-shaped grooves. The sliders are embedded in the V-shaped grooves so that the slide plate and the vehicle slide rail form a sliding connection.

[0013] Furthermore, it also includes a first housing, the upper surface of which is provided with the sliding drive mechanism. One end of the slide plate is provided with a carrier, and the other end is provided with a door panel that is perpendicularly connected to it. One side panel of the housing is provided with an opening that matches the shape of the door panel. The door panel is driven to move along the carrier slide rail by a carrier cylinder to realize the opening or closing of the opening.

[0014] Furthermore, the inner wall of the first box is covered with wave-absorbing material, the carrier is located on the upper surface of one end of the slide plate, and the door panel is provided with a drawer handle.

[0015] The beneficial effects of this utility model are:

[0016] 1. The pressure block of this utility model is connected to the upper cover plate by four evenly distributed spring pins, providing uniform elastic pressure, which can effectively fix the product while avoiding surface damage or deformation caused by hard contact. The spring pins and pressure block are made of plastic steel, which combines elasticity and wear resistance, ensuring stable fixing force and long-term durability in high-frequency testing.

[0017] 2. The sliding drive mechanism of this utility model drives the slide plate to move along the double V-shaped slide rail via the carrier cylinder, realizing the automated entry and exit of the carrier into and out of the test position, reducing manual operation time and errors, ensuring smooth movement, and avoiding signal deviation caused by vibration. The two ends of the slide plate are slidably connected to the V-shaped slide rail through sliders, eliminating the possibility of horizontal deviation, so that the carrier always maintains precise alignment during entry and exit, improving the reliability of test results.

[0027] Example

[0028] like Figure 1-3 As shown, an extended sliding rail carrier for testing radar vehicle lights includes a carrier 18. The carrier 18 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. The pressure block 11 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.

[0029] 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.

[0030] 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, creating a sliding connection between the slide plate 6 and 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.

[0031] like Figure 4 As shown, in a preferred embodiment, it further includes a first housing 16, the upper surface of which is provided with the sliding drive mechanism. One end of the slide plate 6 has a carrier 18 on its upper surface, and the other end has a door panel 9 vertically connected to it. One side panel of the housing has an opening 15 matching 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 inner wall of the first housing 16 is lined with absorbing foam (HS-P3 absorbing cone foam). The door panel 9 has a drawer handle. The door panel 9 is vertically connected to the slide plate 6, so that the movement of the carrier 18 synchronously drives the opening and closing of the door panel 9. 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 absorbing foam lining the inner wall further prevents external electromagnetic interference.

[0032] The working process of this utility model is as follows: The operator activates the sliding drive mechanism via the control panel 31. The cylinder 8 of the carrier 18 drives the slide plate 6 to move along the V-shaped slide rail, causing the carrier 18 to move 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 in the positioning groove 14, ensuring that it is completely matched with the positioning groove 14. Subsequently, the operator closes the upper cover plate 2 of the fixture, and the buckle 12 assembly automatically locks through elastic deformation. The sliding drive mechanism is then activated again via the 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 airtightness of the test environment. After the test is completed, the cylinder moves in the reverse direction, and the carrier 18 automatically exits the test position. The operator unlocks the buckle 12 via the locking handle 3, removes the radar headlight, and replaces it with the next product to be tested.

[0033] In summary, this vehicle, through the combination of flexible fixing and sliding drive mechanism, not only avoids deformation or damage to the radar headlights, but also improves testing efficiency and ensures the accuracy and reliability of test results.
