Description

An adjustable wave transmission performance testing device Technical Field

[0001] This utility model relates to the field of automobile production equipment, and in particular to an adjustable wave transmission performance testing device. Background Technology

[0002] With societal development, more and more families are choosing to own private cars. To ensure vehicle safety during driving, multiple radars are typically installed around the vehicle for obstacle detection. To maintain the vehicle's aesthetics and overall strength, existing radar installations usually do not involve opening holes in the car body. Instead, a metallic coating is sprayed onto the car body surface, allowing the radar to be directly installed inside. The metallic coating reduces radar band obstruction, improving aesthetics without affecting radar operation. However, it is difficult to achieve a uniform thickness of the metallic coating when spraying it onto the car body. To ensure the radar functions properly after the metallic coating is applied, the radar's wave transmission performance needs to be tested. Existing testing equipment is typically installed in a fixed position, and testing is performed by adjusting the angle and position of the sample to be tested. This has limitations, and the thickness of the car body varies between different parts or models, making it difficult for existing testing equipment to adjust the distance between the radiating and receiving components. Summary of the Invention

[0003] To overcome the shortcomings of the existing devices mentioned above, this invention provides an adjustable wave transmission performance testing device.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: an adjustable wave transmission performance testing device, including a robotic arm, with a fixed component rotatably connected to the end of the robotic arm. A bidirectional lead screw is mounted in the middle of the fixed component, and a rotating shaft is arranged horizontally in the fixed component and perpendicular to the bidirectional lead screw. The rotating shaft and the bidirectional lead screw are rotatably connected by a bevel gear. A radiating component and a receiving component are symmetrically arranged at both ends of the bidirectional lead screw. The radiating component includes a base and a radiating end, with the radiating end located at the inner end of the base. A movable sleeve that cooperates with the bidirectional lead screw is fixedly connected to the side of the base near the fixed component. Guide rods are fixedly connected to both sides of the movable sleeve and on the base. Guide holes that fit with the guide rods are opened on the side wall of the fixed component. The receiving component has a structure that is largely the same as the radiating component, except that the end located at the inner end of the base of the receiving component is the receiving end. The center lines of the receiving end and the radiating end are located on the same straight line. In use, rotating the rotating shaft drives the bidirectional lead screw to rotate, causing the receiving components and radiating components on both sides to move linearly along the direction of the guide rods.

[0005] Preferably, a limit block is fixedly connected to one end of the guide rod inside the fixing member to prevent excessive displacement of the receiving and radiating components during use.

[0006] Preferably, the base includes a fixing plate and an end fixing block. The fixing plate is located between the end fixing block and the fixing member. The fixing plate has a plurality of mounting holes for fixing the end fixing block. The detection range of the detection head can be improved by adjusting the installation position of the end fixing block.

[0007] Preferably, one end of the rotating shaft extends out of the fixing member and is fixedly connected to a handwheel, making it convenient for the operator to rotate the rotating shaft.

[0008] Preferably, an angle adjustment device is provided between the robotic arm and the fixed component. The angle adjustment device includes a U-shaped arc end at the end of the robotic arm, and a rotating component fixedly connected to the fixed component is provided in the middle of the U-shaped arc end. The rotating component and the arc end are rotatably connected by an adjusting shaft. An adjustment hole is formed on the surface of the arc end. Several fixing holes are formed on the rotating component to cooperate with the adjustment holes. In use, the rotating component is rotated to adjust the radiating component and the receiving component to the required angle, and the bolts are screwed into the fixing holes and the adjustment holes to complete the fixation.

[0009] The beneficial effects of this invention are that the robotic arm enables the detection equipment to detect samples of different angles and shapes, providing high adaptability. Furthermore, the distance between the radiating and receiving components can be adjusted according to the thickness of the object being detected to improve detection accuracy.

[0018] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0019] As shown in Figures 1-4, an adjustable wave transmission performance testing device includes a robotic arm 1. A fixing member 2 is rotatably connected to the end of the robotic arm 1. A bidirectional lead screw 3 is mounted in the middle of the fixing member 2. A rotating shaft 12, perpendicular to the bidirectional lead screw 3, is horizontally arranged within the fixing member 2. The rotating shaft 12 and the bidirectional lead screw 3 are rotatably connected via a bevel gear. A radiating component 4 and a receiving component 5 are symmetrically arranged at both ends of the bidirectional lead screw 3. The radiating component 4 includes a base 6 and a radiating end 7. The radiating end 7 is located on the inner end of the base 6, near the fixing member 2. A movable sleeve 9 is fixedly connected to the movable sleeve 9 and used in conjunction with the bidirectional lead screw 3. Guide rods 10 are fixedly connected to the base 6 on both sides of the movable sleeve 9. The side wall of the fixing part 2 is provided with guide holes 11 that fit with the guide rods 10. The receiving part 5 and the radiating part 4 have roughly the same structure, except that the end provided on the inner end of the base 6 of the receiving part 5 is a receiving end 8. The center lines of the receiving end 8 and the radiating end 7 are located on the same straight line. In use, rotating the shaft 12 drives the bidirectional lead screw 3 to rotate, which drives the receiving parts 5 and the radiating parts 4 on both sides to move linearly along the direction of the guide rods 10.

[0020] The guide rod 10 is fixedly connected to a limiting block 13 at one end inside the fixing member 2, which prevents the receiving component 5 and the radiating component 4 from excessive displacement during use.

[0021] The base 6 includes a fixing plate 14 and an end fixing block 15. The fixing plate 14 is located between the end fixing block 15 and the fixing member 2. The fixing plate 14 has a plurality of mounting holes 16 for fixing the end fixing block 15. The detection range of the detection head can be improved by adjusting the installation position of the end fixing block 15.

[0022] One end of the rotating shaft 12 extends out of the fixing member 2 and is fixedly connected to the handwheel 17, which makes it convenient for the operator to rotate the rotating shaft 12.

[0023] An angle adjustment device is provided between the robotic arm 1 and the fixed component 2. The angle adjustment device includes a U-shaped arc end 18 at the end of the robotic arm 1. A rotating component 19 fixedly connected to the fixed component 2 is provided in the middle of the U-shaped arc end 18. The rotating component 19 and the arc end 18 are rotatably connected by an adjusting shaft 20. An adjustment hole 21 is formed on the surface of the arc end 18. Several fixing holes 22 are formed on the rotating component 19 to cooperate with the adjustment holes 21. In use, the rotating component 19 is rotated to adjust the radiating component 4 and the receiving component 5 to the required angle, and the bolts are screwed into the fixing holes 22 and the adjustment holes 21 to complete the fixation.

[0024] During installation, the receiving component 5 and the mounting component 4 are installed into the appropriate mounting holes 16 according to the required width of the plate for wave transmission performance testing. Then, the handwheel 17 is turned to drive the rotating shaft 12 and the bidirectional lead screw 3 to rotate. The receiving component 5 and the emitting component 4 on both sides of the bidirectional lead screw 3 move linearly along the direction of the guide rod 10 under the action of the bidirectional lead screw 3 and the moving sleeve 9. When the appropriate spacing is adjusted, the rotation is stopped. The rotating component 19 is rotated to adjust the emitting component 4 and the receiving component 5 to the required angle, and the bolts are screwed into the fixing holes 22 and 21 to complete the fixing. In use, the item to be tested is located between the emitting end 7 and the receiving end 8. The emitting end 7 releases waves of a fixed frequency band, and the receiving end receives the waves remaining after passing through the item, thereby testing the wave transmission performance of the item.

[0025] This design is ingenious. The robotic arm enables the detection equipment to detect samples of different angles and shapes, giving it high adaptability. Furthermore, the distance between the radiating and receiving components can be adjusted according to the thickness of the object being detected to improve detection accuracy. Additionally, the mounting position of the end fixing block can be adjusted via the fixing plate and mounting holes to increase the detection range of the detection head. Moreover, the angle adjustment device can be used to adjust the angle between the radiating and receiving components.

[0026] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
