Description

Technical Field

[0001] This invention relates to the field of electronic testing technology, and in particular to a multifunctional test fixture for electronic experiments. Background Technology

[0002] To meet the evolving experimental measurement needs in the field of electronic science, researchers have established various experimental environments and set up experimental instruments. The required instrument racks vary widely in size, structure, and materials. However, most instrument racks utilize existing commercial instrument cabinets or are custom-made, limiting their application to specific experimental environments. Furthermore, the large size and weight of most instrument racks lead to high costs and difficulties in installation and relocation. After the instrument rack design is completed, there is usually little space available for later modifications and additions to meet new measurement requirements. Purchasing new instrument racks, on the other hand, incurs additional economic and labor costs.

[0003] Industrial profiles are a type of aluminum alloy material with varying mechanical and chemical properties depending on the proportions of alloys added. Their cross-sectional shapes are typically textured to facilitate the insertion of nuts, and the oxidized surface provides an attractive appearance, resistance to dirt, and easy cleaning. Different profile specifications can be selected based on load-bearing requirements during assembly. Using matching profile accessories, interconnection is achieved via screws and nuts, making it environmentally friendly, easy to install and disassemble, and portable. my country is the world's largest producer of aluminum profiles, thus also possessing advantages such as low price and ample supply.

[0004] In summary, this paper proposes an instrument rack design based on industrial profiles. It boasts advantages such as low cost, environmental friendliness, diverse structures, and high flexibility; it also retains the reliability and robustness of traditional instrument racks. Its high flexibility allows for multiple uses, and the rack can be moved in different environments to save costs. Therefore, it can meet the instrument placement needs in various testing environments and the new demands brought about by technological advancements. Summary of the Invention

[0005] The main objective of this invention is to provide a multifunctional test fixture for electronic experiments, which aims to solve existing technical problems.

[0006] To achieve the above objectives, the present invention provides a multifunctional electronic experimental testing rack, including a frame. The frame is modularly designed and divided into a first space, a second space, a third space, a fourth space, a fifth space, and a sixth space by metal plates. The first space is equipped with a network router, the third space is equipped with an industrial control computer, the fourth space is equipped with testing instruments, and the sixth space is equipped with a power supply.

[0007] Furthermore, the frame is composed of profiles forming the main frame, and these profiles are made of aluminum alloy. Thin metal sheets serve as space partitions and a platform for supporting instruments and equipment.

[0008] Furthermore, the outer frame is preferably a cuboid structure, but other forms such as cylinders can also be used depending on the test results. The various profile frames and metal sheets are connected and fixed using screws and nuts.

[0009] Furthermore, the height of each layer of the frame and the position of the metal space partition can be adjusted in real time according to test requirements by adjusting screws and nuts.

[0010] Furthermore, the bottom of the frame is equipped with four horizontally adjustable and lockable casters, which are preferably made of rubber material.

[0011] Furthermore, the frame is equipped with a power strip, GPIB cable, network cable, etc., which are fixed by screws, nuts, or cable ties.

At the same time, this test rack has sufficient spare space to add functional modules as needed.

[0021] 6. The multi-purpose electronic experimental testing instrument rack proposed in this patent has an industrial control computer and integrates modules such as a data acquisition card and a signal generator. A keyboard tray and a display are also installed on the instrument rack, facilitating real-time program control and data acquisition of various testing instruments via the industrial control computer. Data acquisition and processing can also be achieved by remotely controlling the industrial control computer via a network.

[0022] 7. The modular design method proposed in this patent allows for real-time adjustment of the types and quantities of instruments according to testing needs. Furthermore, the space occupied by each instrument in the instrument rack can be adapted by changing the shelf height, installing / removing partitions, etc., thus achieving optimal resource and space utilization.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1 The present invention provides a multifunctional electronic experimental test rack, including a frame 1.

It can not only adapt to the needs of various functional module sizes, but also facilitates indoor or outdoor use.

[0029] Preferably, using all-metal materials facilitates instrument grounding and static electricity elimination. Further encasing the frame with metal plates or absorbing materials can achieve overall or partial internal electromagnetic compatibility or electromagnetic shielding.

[0030] In one embodiment, the frame 1 preferably adopts a layered rectangular three-dimensional structure, but a cylindrical structure or the like can also be used. The height of each layer can be adjusted according to the height of the instrument or equipment.

[0031] In one embodiment, a cooling fan is integrated on the frame 1. The heat dissipation methods of this invention are divided into passive and active heat dissipation: active heat dissipation uses a fan for air cooling, but liquid cooling such as water cooling or oil cooling should fall within the scope of protection of this invention's patent; passive heat dissipation utilizes the good thermal conductivity of the metal frame and thin metal plate. The combined use of these two methods can meet the heat dissipation needs of multiple devices operating simultaneously.

[0032] In one embodiment, the bottom of the frame 1 is equipped with four horizontally adjustable and lockable casters 6.

However, the use of plastic or metal materials should also be considered within the scope of protection of this invention.

[0033] In one embodiment, a power strip 7 is provided on the frame 1, and the power strip 7 is fixed by cable ties. This facilitates convenient power connection for electronic devices and makes the wiring more organized.

[0034] In one embodiment, the industrial control computer 3 includes an industrial control computer host 31 and a display screen 32 located in the third space c, a mouse and keyboard 33 located in the fifth space e, and computer peripherals including a large-capacity hard disk. General additions or subtractions to specific functions should still be considered within the scope of protection of this invention patent. This facilitates real-time data recording and processing.

[0035] Specifically, the industrial PC 3 integrates a high-speed data acquisition card and a signal generator module. It can achieve real-time program control and data acquisition of various testing instruments, and can also be remotely controlled via network routing devices to achieve data acquisition and processing.

[0036] It should be noted that if the embodiments of the present invention involve directional indicators such as up, down, left, right, front, back, etc., the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicators will also change accordingly.

[0037] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied. Furthermore, "multiple" refers to two or more. Moreover, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent.

[0038] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
