Embodiment Construction

[0092] The present invention is further described below in conjunction with accompanying drawing:

[0093] The main function of this structure is mainly composed of three different modules, namely: 1. Pressure analysis module (only the seat back part is included in the figure); 2. Push rod module with dynamic hydraulic pressure; 3. Unpowered rotation module;

[0094] The implementation process is as follows:

[0095] Before the patient sits down, the elongation of 1 push rod is x0=0, which is horizontal to the ground, and the seat starts to enter the start-up phase.

[0096] After the patient sits down, the body lies back, leaning against the back of the chair (not shown in the figure), and the buttocks are close to the rear end of the seat. The seat is activated.

[0097] 1 (including 1 on the foot rest and the back of the chair) obtain data through pressure feeling, obtain the pressure distribution data of the person at this time, and fit the space vector of the center of ...

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...
