An experimental bed for automatic control system mechanical properties

Abstract

The invention relates to an experimental bed capable of automatically controlling system mechanical properties. The experimental bed comprises a mattress and a bedstead, wherein the mattress consists of a bed core, a fabric composite layer (11), a latex foam bedding layer (12) and a spring substrate plate (15), and the bed core consists of evenly arranged independent bagged springs (13); the bagged springs (13) are independently and fixedly arranged on the spring substrate plate (15) and are provided with linear displacement transducers (14), and the mattress is provided with an adjustable comfort region (8) capable of detecting the morphological changes in human spine; the spring substrate plate consists of a plurality of independent small substrate plates, and each small substrate plate is used for supporting two horizontal rows of independent bagged springs (13); and a linear permanent magnet reciprocating motor (21) is respectively arranged under each small substrate plate. The bagged spring compression amount information collected by an information collector is transmitted to a data processor to obtain the human-bed interface indentation amount. The quantitative research on the human-bed interface shape and pressure in real sleeping and natural prone position states is realized.

Description

technical field [0001] The invention relates to an ergonomic experiment bed. Background technique [0002] The purpose of the ergonomic design of a bed or mattress is to provide optimal support conditions for the human body through the optimized design of the bed or mattress performance for people to rest, so that people's energy and physical strength can be maximized during rest or sleep. degree of recovery. However, the support of the bed or mattress to the human body is the result of the complex biomechanical relationship between the person and the bed. It mainly includes two aspects: one is the matching relationship between the surface deformation of the mattress and the shape of the human body; Interaction of "forces" between beds, both of which are related to sleep disturbance and comfort in the lying position. Therefore, quantitative research on these two aspects is of great significance to the humanized design and customized production of mattresses. In addition, ...

Therefore, a scientific and reasonable bed or mattress support design should be based on the personalized human body, that is, to establish the best matching relationship between the person and the bed based on the characteristics of the personalized human body, and if this is done according to the traditional method (using a commercial bed furniture or mattress) to study, it needs to consume a lot of manpower, material and financial resources, and it is very difficult to realize

At present, the experimental bed used for the study of the matching relationship between human and bed only has some specific devices for quantitative testing of spine morphology, but this device requires the human body to maintain a specific posture and position during the test, so that the spine morphology It just falls on the linearly arranged sensors, so it cannot truly reflect the natural sleeping position, and can only quantitatively reflect the shape of the interface between the person and the bed from the perspective of a one-dimensional curve, and cannot truly reflect the person-bed from the three-dimensional space At the same time, it cannot reflect the pressure relationship between the person and the bed

In addition, although there are some adjustable fluid mattresses such as water mattresses and air mattresses on the market, these mattresses are inherently deficient in terms of stability, support, and air permeability, which leads to the market for such products. At the same time, because the quantitative adjustment of the mechanical properties of mattresses cannot be realized, it is not suitable for quantitative research on the matching relationship between people and beds.
