Description

Method and structure for adjusting regional elasticity of mattress

Technical Field

The invention relates to furniture, in particular to a mattress of a bed, and particularly relates to a method and a structure for adjusting the elasticity of the mattress in different regions.

Background

In the prior art, a bed is a necessity of people's life, nearly one third of the life of a person is read on the bed, a mattress is a product for improving the sleep quality of the human body, the comfort level of the people can be improved, simultaneously, the physiological natural form of the human body in sleep can be maintained, the natural physiological bend of the human vertebra generated by evolution is a natural physiological form which needs to be kept by the human body all the time, when the natural physiological bend of the vertebra is changed by external force for a long time, the vertebra can not keep a natural vertical state on the middle section of the human body, the vertebra of the human body generates pathological abnormality, and various problems occur to the human body, therefore, the human body always keeps the natural physiological form in sleep, and the mattress is very significant for protecting the health of the human body. At present, although the mattress with multiple materials and structural forms can maintain the natural physiological form of the human body during sleeping to a certain extent through the design of materials and structures, the height, the weight, the fat and the like of each individual of a person are greatly different, the maintenance to a certain extent is a rough one-to-many adaptation, and cannot really meet the individual of each person, so that a mattress is necessary to be designed, the natural physiological form of each person is maintained to the maximum extent through adjusting the specific parameters of the mattress according to the specific physiological form of the individual body of each person, and the mattress plays a good role in protecting the body of the person while providing good sleeping comfort. This technology is awaiting development.

For example, application No. 201710113395. X discloses a technical solution entitled "an intelligent mattress adjustable according to sleeping posture" which is: the upper surface of the mattress body is provided with a movable groove, a plurality of fixed boxes are arranged in the movable groove, a driver and a push rod connected with the driver are arranged in each fixed box, the top end of each push rod is connected with a fixed plate, and a first inductor is arranged on each fixed plate; the driver can drive the push rod to vertically extend or retract; the fixing plate is provided with a plurality of first sensors; the first pressure sensor is used for acquiring the pressure born by the fixing plate, the processor is used for matching the pressure with the sleeping posture model so as to determine the sleeping posture of the user, the pressure parameters of the fixing plates mapped by the sleeping posture of the user are determined according to the preset mapping relation, and the driver is used for driving the push rod to extend or contract according to the pressure parameters of the fixing plates until the pressure born by the fixing plates reaches the pressure limited by the pressure parameters.

Analyzing the technical solution of this patent results in: because the hydraulic machine is adopted to drive each hydraulic cylinder, each hydraulic cylinder needs to be driven independently, so that mechanical equipment below the whole mattress is very complicated, the power consumption is a matter which needs to be considered, secondly, each hydraulic cylinder needs an electric driving circuit, each first sensor needs an A/D conversion circuit, although an input and output circuit can be simplified in a scanning mode, the number of the second sensors is more, therefore, I/O ports of the MCU are enough, and the two problems are not a problem in the technical sense, but the following problems are important: failure rate and life. The technical scheme is so numerous and complicated that faults are inevitable, and once a certain unit is in a high convex or deep concave fault, the sleep of a user is directly influenced, so that the mattress cannot be applied. Therefore, it is the goal we pursued to simplify the technical solution to achieve the design goal.
