Problems solved by technology

However, the size of a notebook computer is often several times larger than that of a mobile phone, and when testing, the notebook computer needs to be operated, so it is necessary to open the notebook computer display, which increases its volume.
Also, when the laptop is opened, its center of gravity changes, making it difficult to hold a grip if using a gripping device
Moreover, due to the small size of the mobile phone, various angles need to be constantly changed during the test, so its structure is very complicated, the operation is troublesome, and the cost is high

Abstract

The invention discloses a laptop support with adjustable height for an SAR test. The laptop support is characterized in that: the laptop support comprises a loading plate and a bottom plate; and the loading plate and the bottom plate are connected through a lifting device. The laptop support with the adjustable height for the SAR test has a simple structure and convenient operation, and is suitable for placing a laptop in the SAR test. As a loading area can be enlarged, even if the laptop is placed on the support after being opened, the laptop can be placed on the support stably without a risk of dropping.

Description

technical field [0001] The invention relates to a height-adjustable notebook computer support for SAR testing. Background technique [0002] With the development of information technology, when the public enjoys various conveniences brought by wireless communication equipment, they are increasingly concerned about the impact of electromagnetic radiation from wireless communication terminals on human health; governments of various countries have always attached great importance to this indicator of wireless communication terminals ; Europe, the United States, Australia, New Zealand, Japan, South Korea and Taiwan have all formulated local or national "radio frequency and microwave radiation management" regulations or directives; the United States and Taiwan also require mobile user terminal manufacturers to mark on product packaging "The electromagnetic radiation of this product to the human body is within the safety limit" and other words. Therefore, it is very important to ...
