Double-platform wave-absorbing sharp cone transverse positioning system

Abstract

This invention provides a dual-platform absorbing tip transverse positioning system, installed on the floor of an anechoic chamber to simulate different radio wave environments. The system consists of two parallel hydraulic platforms with densely arranged absorbing tips on them, and a raised floor is mounted on the hydraulic platforms. The hydraulic platforms are driven by hydraulic cylinders to lift and lower scissor supports. Sprockets are located at both ends of the platforms, driven by chains, and a transverse motor is also provided. The motor drives the sprockets through gear engagement, causing the absorbing tips on the platforms to move laterally. The raised floor, originally a metal reference surface, can be adjusted to a non-reflective environment according to testing requirements. The hydraulic platforms rise, driven by the transverse motor, and the absorbing tips of the two platforms unfold laterally, providing a non-reflective test. The aforementioned actions are reversed, causing the platforms filled with absorbing tips to retract and disappear under the raised floor. This system can flexibly switch between different testing environment conditions to meet the diverse needs of the anechoic chamber.

Description

Technical Field

[0001] This utility model relates to a dual-platform absorbing tip transverse positioning system, and particularly to a dual-platform absorbing tip transverse positioning system applied in an anechoic chamber. Background Technology

[0002] Please refer to Anechoic Chamber. Figure 1 As shown, it is a specially designed enclosed space, mainly used to simulate an environment with "no electromagnetic wave reflection" or "low electromagnetic interference"; its significance and function cover fields such as scientific research, product development, and compliance testing.

[0003] In eliminating external interference, anechoic chambers provide a "clean" testing environment by shielding external electromagnetic waves (such as broadcasts, Wi-Fi, and cell phone signals), ensuring that experimental results are unaffected by external noise. Regarding simulating free space, in real-world environments, electromagnetic waves exhibit multipath effects due to object reflection and ground scattering. Anechoic chambers utilize absorbing materials (such as ferrite or carbon-based materials) to absorb electromagnetic waves, simulating the infinite propagation of electromagnetic waves in free space, making test results closer to theoretical values. In the field of regulatory compliance verification, electronic equipment must comply with international electromagnetic compatibility (EMC) standards (such as FCC and CE); anechoic chambers are crucial facilities for verifying whether equipment generates excessive electromagnetic radiation (EMI) or is susceptible to interference (EMS).

[0004] Anechoic chambers are a fundamental infrastructure for the development of modern electronic technology. Their core value lies in providing a controllable and repeatable electromagnetic environment, ensuring that products meet performance and regulatory requirements from research and development to mass production. With the advancement of high-frequency communication (such as 6G) and autonomous driving technologies, the design and application of anechoic chambers will continue to evolve.

[0005] Commonly known anechoic chambers are divided into fully anechoic chambers and semi-anechoic chambers. Fully anechoic chambers have all six walls covered with absorbing material, completely eliminating reflections, and are suitable for high-precision antenna testing or high-frequency (such as millimeter-wave) applications. Semi-anechoic chambers have a conductive floor to simulate ground reflections in a real environment and are commonly used for EMC testing (such as automotive electronics requiring CISPR compliance). (Standard 25); however, most anechoic chambers are customized to meet specific needs. Large anechoic chambers are expensive to build due to their large size. Considering the cost and testing requirements, existing anechoic chambers often require testers to carry the absorbing cones to their positions themselves (semi-anechoic chambers simulate the conditions of full anechoic chambers), resulting in wasted time in laying absorbing materials and installation positioning errors. In addition, a large amount of absorbing cone material requires a large storage space, causing inconvenience and space pressure. This is not ideal and urgently needs improvement. Therefore, considering cost and many other factors, the designer of this project is actively developing a composite and multi-purpose anechoic chamber that can meet the needs of various experimental conditions.

[0006] Based on the above reasons, it is clear that the existing technology still has shortcomings in use and needs to be improved. In view of this, the designer of this case actively researched and, with many years of experience in the research and development of related products, and through continuous experimentation and improvement, finally came up with the design of this utility model. Utility Model Content

[0007] The purpose of this invention is to provide a dual-platform absorbing cone transverse positioning system to solve the aforementioned technical problems in the prior art.

[0008] To achieve the above objectives, this utility model provides a dual-platform absorbing cone transverse positioning system. The system includes: a pair of hydraulic platforms, each with a hydraulic cylinder at its bottom; the piston shaft of each cylinder is connected to and drives a scissor lift bracket; the scissor lift bracket's scissor angle changes to achieve platform lifting and lowering; a platform is positioned at the upper end of the scissor lift bracket; a sprocket and chain are transversely arranged on the platform, and a transverse motor drives the sprocket and chain to drive the absorbing material on the platform to translate; and a plurality of absorbing cones, shaped like cones, which facilitate... To reduce reflection and scattering and ensure that electromagnetic waves are effectively absorbed from all angles, a pair of raised floors, each in the form of a square frame, are provided with a metal plate on the upper surface of the frame to serve as the raised floor. The platform at the top of the pair of hydraulic platforms supports the pair of raised floors. Between the raised floors and the platform at the top of the hydraulic platform, a plurality of wave-absorbing cones are arranged in an orderly manner. By means of the lifting and lowering of the hydraulic platform and the traverse motor in combination with the sprocket and chain drive, the wave-absorbing cones can be laterally deployed and installed, or converged and stored in an automated switching operation.

[0009] This system is installed on the floor of an anechoic chamber to simulate different radio wave environments. It consists of two parallel hydraulic platforms with densely packed absorbing cones on each platform, and a raised floor is mounted on top of these platforms. The hydraulic platforms are raised and lowered by hydraulic cylinders driving scissor lifts. A sprocket and chain are located at the lateral end of each platform for transmission, and a lateral movement motor is also provided. The motor, through gear engagement with the sprocket, drives the absorbing cones on the platform to move laterally. The raised floor, originally a metal reference surface, can be adjusted to a reflection-free environment according to testing requirements. When this is achieved, the hydraulic platforms rise, driven by the lateral movement motor, and the absorbing cones on both platforms unfold laterally, providing reflection-free testing. The reverse operation retracts the aforementioned action, causing the platforms filled with absorbing cones to retract and disappear beneath the raised floor. This system allows for flexible switching between different testing environment conditions, meeting the diverse needs of the anechoic chamber.

[0010] The transverse motor drives the sprocket and chain through gear meshing to move the wave-absorbing cones in translation.

[0011] The scissor lift bracket consists of two sets of scissor lift links and a connecting rod.

[0012] The sprocket and chain can be connected to the trolley or rollers on the platform.

[0013] This positioning system can be expanded from two platforms to four platforms or other multiples as needed for actual use. The aforementioned dual-platform absorbing cone transverse positioning system uses a pair of hydraulic platforms, and the number of platforms can be increased according to the size of the anechoic chamber and the area of ​​use.

[0014] Furthermore, in this dual-platform absorbing cone transverse positioning system, the raised floor on the hydraulic platform is flush with the ground of the anechoic chamber; that is, the hydraulic platform is installed between the ground floor and the ground of the anechoic chamber.

[0015] The main advantage of this invention is that it provides a dual-platform absorbing cone transverse positioning system that can automatically switch between a metal reflective surface and a non-reflective surface covered with absorbing cones. This combined use can significantly reduce the cost of building an anechoic chamber and significantly improve its utilization rate.

[0016] A secondary advantage of this invention is that it provides a dual-platform absorbing tip cone transverse positioning system, which is designed to improve and reduce the time spent by testers when handling, laying or moving absorbing materials, thereby saving manpower and improving work efficiency.

[0017] Another advantage of this invention is that it provides a dual-platform absorbing tip transverse positioning system. Through the transverse positioning design and precise motion control of this system, the absorbing tip can be accurately placed in the designated position to achieve the best effect.

[0018] Another advantage of this utility model is that it provides a dual-platform absorbing tip transverse positioning system. Through ingenious structural design and precise motion control, the absorbing tip can be stored in an orderly manner in the internal space of the raised floor.

[0030] Please see Figure 2 As shown, this is a schematic diagram of the structure of the dual-platform absorbing cone transverse positioning system of this utility model located on the floor of an anechoic chamber; in the aforementioned prior art, conventional anechoic chambers are divided into "fully anechoic chambers" and "semi-anechoic chambers," the difference being that the floor is either a non-reflective environment covered with absorbing materials, or a conductive floor simulating ground reflection in a real environment; therefore, in Figure 2 The raised floor 20 refers to the "conductive floor". The raised floor 20 is mounted on the hydraulic platform 30 below it. The wave-absorbing cone 50 is housed in the internal space of the raised floor 20. The hydraulic platform 30 is mounted on the ground floor 10. The upper surface of the raised floor 20 is flush with the floor of the anechoic chamber.

[0031] Please see Figure 3 The diagram shows the initial state structure of the dual-platform wave-absorbing cone transverse positioning system of this invention. This invention consists of two parallel hydraulic platforms 30 and a plurality of wave-absorbing cones 50 densely arranged on the platform 34. The raised floor 20 is mounted on the platform 34 of the hydraulic platform 30. The hydraulic platform 30 drives the scissor lift bracket 36 through the hydraulic cylinder 38. The scissor lift bracket 36 is a support body composed of two sets of scissor lift connecting rods and a connecting rod. At each of the transverse ends of the platform 34, there are sprockets 40 and 42 and a chain 44. A transverse motor 46 is also configured. The transverse motor 46 meshes with the sprocket 42 through gears, or can be connected to the trolley or rollers on the platform 34 to drive the wave-absorbing cones 50 on the platform 34 to move laterally, thus performing translational transport of the wave-absorbing cones 50.

[0032] Please see Figure 4 The diagram shows the operation of the left hydraulic platform of the dual-platform wave-absorbing cone lateral positioning system of this invention; the left hydraulic platform 30 drives the scissor lift bracket 36 through the hydraulic cylinder 38 to achieve the lifting action; please refer to... Figure 5 The diagram shows the operation of the left hydraulic platform of the dual-platform wave-absorbing cone transverse positioning system of this invention, where the wave-absorbing cone is transversely moved to the upper surface of the right elevated floor. Driven by the transverse motor 46, the transmission is achieved through gear meshing. The sprocket 42, via the chain 44, drives the sprocket 40, causing the wave-absorbing cone 50 on the platform 34 to move laterally to the right, sliding to the upper surface of the right elevated floor 20.

[0033] Please see Figure 6 The diagram shows the state of the absorbing tip cone after the left hydraulic platform of the dual-platform absorbing tip cone transverse positioning system of this utility model has been reset; when the absorbing tip cone 50 is slid to the right, the originally raised left hydraulic platform 30 falls back to its original position; please also refer to... Figure 7 The diagram shows the operation of the right hydraulic platform of the dual-platform wave-absorbing cone transverse positioning system of this utility model. At this time, the right hydraulic platform 30 performs a lifting action, raising the right elevated floor 20, which is covered with wave-absorbing cones 50 inside and out.

[0034] Please see Figure 8 The diagram illustrates the operation of the right hydraulic platform's wave-absorbing cone lateral movement positioning system of this invention, where the wave-absorbing cone is laterally moved to the upper surface of the left elevated floor. Similarly, the wave-absorbing cone 50 on the upper platform 34 of the right hydraulic platform 30 is driven by the lateral movement motor 46 through gear meshing. The sprocket 42, via the chain 44, drives the sprocket 40, causing the wave-absorbing cone 50 on platform 34 to move laterally to the left, sliding to the upper surface of the left elevated floor 20. Please refer to [further details omitted]. Figure 9 The diagram shows the state of the absorbing tip cone after the right hydraulic platform of the dual-platform absorbing tip cone lateral positioning system of this utility model has been reset. After the absorbing tip cone 50 is moved to the designated position on the left elevated floor 20, the right hydraulic platform 30 performs a descent and reset action, and the installation and deployment of the absorbing tip cone 50 is completed.

[0035] Reverse operation, i.e., the action steps are as follows Figure 9 > Figure 8 > Figure 7 > Figure 6 > Figure 5 > Figure 4 > Figure 3 > Figure 2 The convergence, closing, and storage operations of the absorbing tip 50 are completed.

[0036] This invention relates to a dual-platform absorbing tip transverse positioning system that can automatically switch between a reflective metal surface and a non-reflective surface covered with absorbing tips. This combined approach not only significantly reduces the construction cost of the anechoic chamber but also substantially improves its utilization rate. Furthermore, the system reduces the time spent by testing personnel handling, laying, or removing absorbing materials, thereby saving manpower and increasing work efficiency. Through transverse positioning design and precise motion control, the absorbing tips can be accurately placed in the designated position for optimal results. Moreover, the system's ingenious structural design and precise motion control ensure that the absorbing tips can be stored orderly within the raised floor's internal space.

[0037] The dual-platform absorbing cone transverse positioning system consists of a scissor bracket composed of two sets of scissor rods and a connecting rod. The sprocket and chain can drive the trolley or rollers on one platform to move and transport the absorbing cone. Furthermore, depending on the actual usage range in the darkroom, the dual platform can be expanded into a four-platform or multiple-platform system.

Any modifications and refinements made by those skilled in the art without departing from the spirit and scope of the present invention shall fall within the protection scope of the present invention.
