Description
Technical Field
The invention relates to the technical field of contact surface control, in particular to a wireless-control adjustable self-adaptive surface.
Background
Sitting, lying and lying are common behaviors of people, diseases of vertebra and cervical vertebra can be caused by long-time sitting or incorrect sitting, and some patients with vertebra also need external force to keep specific sleeping positions, so that the comfort level of people who lean on sitting and lying can be well improved by adaptively adjusting the contact surfaces of a chair back, a cushion, a mattress and the like, and the sitting and sleeping positions can be assisted to be corrected.
At present, the shape control of the contact surface is mainly realized by elastic materials such as sponge, spring and the like. In addition to the use of elastic materials, some mechanical-based control techniques have emerged for the control of the reclining surface of the back of the chair, due to the limited shape changes of the material, which do not adapt well to all users, such as:
the first scheme is as follows: the bulge part protruding forwards in an arc shape is arranged at the position, corresponding to the waist of a human body, on the backrest, so that when a user uses the seat, the legs cannot be pressed down, blood vessels can be kept smooth, and muscles of the leg lack part cannot be anoxic; meanwhile, the convex part is pressed against the human body, so that the back of the human body is required to be straight, the spine keeps natural bending, and the sitting posture of the human body is corrected.
Scheme II: the sitting posture is adjusted through the ball head hinge which can incline in any direction, when the sitting posture of a person is incorrect, discomfort can be generated, and the discomfort can 'urge' the person to automatically adjust the sitting posture, so that the aim of correcting is fulfilled. The scheme can also adjust the pre-tightening spring pressure of the sitting posture correction chair, the height of the back plate, the front position and the rear position of the back plate and the height of the panel, so that the sitting posture correction chair is suitable for people of different body types.
Above scheme only can realize correcting the position of sitting, can not adjust the comfort level of using, carries out the position of sitting adjustment through reducing the comfort level to a certain extent, and the function is single. The control of the bed surface is similar to the condition of the chair back, and at present, the control is mainly based on the characteristics of the leaning material, such as latex material, sponge material and the like. Of course, there are also zonal controls of the mattress, such as:
the first scheme is as follows: the inner core of the mattress is formed with a plurality of pocket springs, each pocket spring being arranged in two lateral groups and one central group. The central group is disposed between the two lateral groups and extends in a direction parallel to the long sides of the mattress. The springs in each lateral group are compressed independently of the springs in the other lateral groups.
Scheme II: a plurality of small chambers having fluid chambers are provided on the upper surface of a base for supporting a human body, and the lying comfort is improved when a user performs a back-raising action.
The third scheme is as follows: the mattress is provided with a plurality of sensors, each sensor is used for detecting the force born by the corresponding elastic unit so as to generate a corresponding measured value and analyze the measured data, but the analyzed data is only used for analyzing the sleep state and cannot control the contact surface. The contact surface of the mattress can not adjust the ideal mode required by the user, and the application range is limited.
