Description

Technical Field

[0001] The utility model relates to the technical field of radar testing, in particular to a radar testing tool. Background Art

[0002] Radar is an electronic device that uses electromagnetic waves to detect targets. Radar emits electromagnetic waves to illuminate the target and receives the echoes, thereby obtaining information such as the distance from the target to the point of emission, the rate of change of distance (radial velocity), direction, and altitude. Commonly used radars in road traffic, such as millimeter-wave radar, are radars that detect in the millimeter-wave band. Millimeter waves typically refer to electromagnetic waves with a frequency range of 30-300 GHz or a wavelength of 1-10 mm. Their short wavelength and wide frequency band enable narrow beams, high radar resolution, and resistance to interference. Millimeter-wave radar can measure the relative distance, velocity, and direction of an object being measured. Initially, it was used in the military. With the development and advancement of radar technology, millimeter-wave radar has been applied to a variety of fields, including automotive electronics, drones, and intelligent transportation.

[0003] With the rapid development of smart transportation, integrated radar and video cameras have emerged, playing a significant role in urban traffic management, highway monitoring, smart parking, and smart public transportation. As the name suggests, integrated radar and video cameras seamlessly integrate radar and video technologies. Combining the long-range detection capabilities of radar with the high-definition recognition capabilities of video, they enable comprehensive, all-weather, and high-precision monitoring of road traffic conditions. This technology not only maintains stable performance in adverse weather conditions but also accurately identifies various traffic participants, providing solid technical support for smart transportation.

[0004] Currently, most of these radar products can only be tested in specific environments using dedicated tooling. However, the existing test tooling is limited by environmental changes, such as the twists and turns, widths, and heights of different road sections, and cannot meet the testing needs of different environments. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a radar test tooling, which is suitable for testing multiple products and covers the testing requirements in various environments.

[0006] This is achieved through the following technical solutions:

[0007] A radar test tooling includes a tripod bracket, a lifting rocker, a common fixed base for equipment, an adapter plate and a clamping tooling. The lifting rocker is connected to the tripod bracket, the common fixed base for equipment is connected to the top of the lifting rocker, the adapter plate is connected to the common fixed base for equipment, the clamping tooling is installed on the adapter plate, and the lifting rocker is used to lift the common fixed base for equipment, the adapter plate and the clamping tooling.

[0008] Further preferably, the triangular bracket has three legs and a sleeve, the three legs are rotatably connected to the sleeve respectively, the lifting rocker includes a lifting rod and a driving member, the lifting rod is movably sleeved in the sleeve, the driving member is connected to the lifting rod, and the driving member is used to lift the lifting rod.

[0009] Further preferably, a spring positioning pin is provided at the connection between the three legs and the sleeve, and a rotating fixing knob is provided at the top of the sleeve.

[0010] Further preferably, the top end of the lifting rod is rotatably connected to a round tube, and the equipment shares a fixed base that is detachably connected to the top end of the round tube.

[0011] Further preferably, the clamping tool comprises a tool base plate and a fixing device clamping push rod, and four fixing device clamping push rods are provided and respectively installed at the four corners of the tool base plate.

[0012] Further preferably, the surface of the tool base of the clamping tool is provided with an anti-static layer to prevent scratches on the product surface.

[0013] Beneficial effects of the utility model:

[0014] 1) This radar test fixture can be raised to different heights via a manual lift lever to accommodate testing in various road gradients. A spring-loaded positioning pin and a manual locking mechanism prevent slipping, ensuring safe testing. The three legs of the tripod support can be rotated and adjusted to accommodate various widths and winding roads. The circular tube and lift lever rotate to adjust the fixture's clamping angle, adapting to diverse testing environments. This covers a wide range of testing requirements, including road testing, traffic light intersections, overpasses, and enclosed areas.

[0015] 2) This new radar test fixture allows different radar products to be tested using an adapter plate that secures the fixture and product to different clamps. Simply replacing the common fixed base and adapter plate allows for multiple configurations to meet testing needs. This reduces the need to raise and lower the tripod for product commissioning, and allows for simultaneous testing of two radar products of the same or different models. This multiple configuration significantly improves testing efficiency.

DETAILED DESCRIPTION

[0021] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0022] refer to Figure 1 and 2 A radar test fixture includes a tripod 1, a lifting joystick 2, a spring positioning pin 3, a rotating and fixing handle 4, a common fixed base 5 for the equipment, an adapter plate 6, and a clamping fixture 7. The tripod 1 can adopt an existing conventional tripod. Before use, the tripod is taken out and unfolded, and the joystick is rotated to the working height. The quick-release plate of the pan-tilt head is removed and the radar is installed on the quick-release plate. The joystick can be used to adjust the height according to the scene to be tested. In this embodiment, the tripod 1 is preferably thickened to improve the stability of the test fixture. The tripod bracket 1 has three legs 8 and a sleeve 9. The three legs 8 are rotatably connected to the sleeve 9 respectively. The three legs 8 support and fix the sleeve 9. The lifting rocker 2 includes a lifting rod 10 and a driving member 11. The lifting rod 10 is movably sleeved in the sleeve 9 of the tripod bracket 1. The lifting rod 10 is raised and lowered by the driving member 11. It can be electric or manual. Preferably, a manual lifting rocker 2 is used, such as the manual type I lifting rod 10 of Shenyang Jiachuang Huizhi Technology Co., Ltd., which can be adjusted to different heights of 3-6 meters. The tripod bracket 1 can bear a load of less than 15kg.

[0023] A round tube 12 is provided at the top of the lifting rod 10 of the lifting rocker 2. The common fixed base 5 of the equipment is detachably connected to the top of the round tube 12. The common fixed base 5 of the equipment is connected to the adapter plate 6. The clamping tool 7 is installed on the adapter plate 6. The preferred round tube 12 is horizontally rotatably connected to the lifting rod 10, and is used to rotate horizontally to adjust the angle of the clamping tool 7.

[0024] The spring locating pin 3 is preferably set at the connection between the three legs 8 and the sleeve 9, and the rotating fixing hand twist 4 is preferably set at the top of the sleeve 9. The lifting rod 10 is locked by the dual fixing method of the spring locating pin 3 and the rotating fixing hand twist 4.

The surface of the tooling bottom plate 13 of the clamping tool 7 is pasted with a 1mm anti-static EVA static layer to prevent scratching the product surface.

[0027] This radar test fixture enables multiple radars to meet various testing needs in multiple scenarios. The specially designed thickened tripod can be adjusted to different heights of 3-6 meters through the manual lifting joystick 2 according to different test scenarios. It is manually locked by the spring positioning pin 3 and the rotating fixed handle 4 to prevent slipping and ensure test safety. The equipment uses a common fixed base 5 fixed to the top of the lifting rod 10 with screws. Different radar products are tested by fixing different clamping fixtures 7 and products through the adapter plate 6, achieving a variety of "deformations" to meet test needs. It reduces the step of debugging the product each time the tripod 1 is lifted. It can also test two radar products of the same model or two different models at the same time. If video is required, a ball camera can also be installed to cooperate with the radar test. The various "deformation" tests greatly improve the efficiency of the test work.

[0028] Test operation of radar test fixture:

[0029] 1. Before testing, adjust the three legs 8 of the specially made thickened triangular bracket 1 to be level.

[0030] 2. Fix the clamping fixture 7 required for the installation test with screws and adjust the angle.

[0031] 3. For products that are fixed with screws for testing, use an angle measuring tool to measure the required angle during initial installation and adjust it accordingly.

[0032] 4. Manually shake the manual lifting rocker 2 to raise the lifting rod 10 to the required height, and fix it firmly through the spring positioning pin 3 and the rotating fixing handle 4.

[0033] 5. Adjust the test direction by fine-tuning the round tube 12 at the top of the lifting rod 10 to meet the test requirements.

[0034] 6. After the adjustment meets the requirements, the test product can be replaced by shaking the manual lifting rocker 2 to lower the lifting rod 10 and continue to complete the test.

[0035] 7. Repeat the above steps to test different products.

[0036] This radar test fixture is suitable for testing a variety of products. Different products with the same mounting method can use the same clamping fixture 7.
