The aluminum alloy case design of electronic products is an important part of the chassis design. The panel design needs to meet the criteria of the chassis design. After determining the enclosure type and size, determine the size of the panel. The selection and layout of various operating and display devices on the panel should be based on the requirements of the electrical schematic diagram, ergonomics, and comprehensive consideration of factors such as shape and ventilation.

1. Ensure the realization of product technical indicators

During the design process, it is necessary to consider the electromagnetic interference and thermal effects between the internal components of the chassis and the thermal effects to improve the stability of the electrical performance; attention must be paid to the strength and rigidity of the chassis to avoid deformation, resulting in poor electrical contact, doors and connectors After vibration, it is stuck or even damaged; corresponding measures must be taken according to the actual working environment and use conditions to improve the reliability and service life of the equipment and ensure the realization of product technical indicators.

2. To facilitate the operation, use, installation and maintenance of the equipment

In order to operate and use equipment effectively, the structural design of the chassis must conform to the psychological and physiological characteristics of people. At the same time, it is also required to have a simple structure and convenient disassembly and assembly. The controller and display device on the panel must be reasonably selected and arranged, and the personal safety of the operator must be considered.

3. Good structure and workmanship

The structure is closely related to the process. Different structures have different processes, and the quality of chassis structure design must be guaranteed by good process measures. Therefore, designers must consider its structure and manufacturability in combination with actual production.

4. Modular and standardized design

Standardization is an important technical and economic policy and management measure of the country. It plays an important role in improving product quality and productivity, ease of use and maintenance, strengthening enterprise management, and reducing production costs. In chassis structure design, it is necessary to minimize the number of special parts, increase the number of general parts, and use standardized and standardized parts, parts and size series as much as possible (use standard library and national standard parts as much as possible).
