Self-adaptive smooth adjustment system and method for seat surface

Abstract

The invention discloses a self-adaptive smooth adjustment system and method for a seat surface. The system comprises a pressure distribution analysis module, an unpowered rotating module and a powered hydraulic push rod module; the unpowered rotating module is of a rotating structure fixed at the tail end of the chair back, the powered hydraulic push rod module is installed at the center below the chair seat and close to the joint of the chair back, and the joint of the chair seat and the powered hydraulic push rod module is of a hinge structure; the pressure distribution analysis module comprises three sets of flexible film pressure sensors, a gravity sensing module and a calculation analysis module, the gravity sensing module is arranged on the chair seat, and the three sets of flexible film pressure sensors are respectively distributed on the chair seat, the chair back and the foot support; and the three sets of flexible film pressure sensors and the gravity sensing module are all connected to the calculation and analysis module. According to the invention, the pressure sensors and pressure data analysis are combined, and the elongation of the push rod is dynamically adjusted, so that the rotation amount of the chair seat is controlled, and the most comfortable angle is set.

Description

technical field [0001] The invention belongs to the technical field of self-adaptive adjustment of a seat surface, in particular to a system and method for self-adaptive smooth adjustment of a seat surface. Background technique [0002] At present, the thickness of the force sensing gasket has reached the thickness of the film, and the accuracy is extremely high. For distributed sensors, a single scanner can support up to 2288 points of sensing unit detection, which can completely pass the analysis surface. Pressure data, use the pressure data as a guide for further operations. [0003] Various hydraulic shafts and hydraulic push rods driven by motors have been widely used in the industry, and the related motion research related technologies are also very mature, and can be dynamically adjusted according to the data through a microcomputer to achieve smooth transition of various motion states . [0004] At present, in view of the current problems that the user is easy to s...

Problems solved by technology

However, the essence of this adjustment method is that it is still difficult for the user to grasp the best comfortable position through blind exploration, and it will not make adaptive adjustments due to changes in the user's physiological characteristics, but simply remember the user's The parameter result after the operation, and then repeat the execution to get this result

And at present, most of the automatic adaptation and force analysis are based on scalars, and the comfort is analyzed only through flattened data.
