Technical Field

[0001] The present invention relates to the technical field of office chairs, and in particular to an ergonomic office chair structure with good fatigue-relieving effect and a use method thereof. Background Art

[0002] Office chairs refer to chairs used by general office staff. According to the needs of different industries, the office chair series is diversified. Among them, the most prominent industry series is the doctor's office chair. The doctor's office chair is mainly used by internal hospital staff. The materials and designs are strictly designed and configured according to the working habits and operating procedures of medical staff. From the material point of view, it can be divided into panel office chairs, steel office chairs, metal office chairs, soft office chairs, etc.

[0003] Existing office chairs are usually ordinary chairs that do not conform to ergonomic design, causing workers to suffer from back pain and fatigue after sitting for a long time. They cannot be adjusted according to the user's body shape, resulting in the user's waist being suspended or overly squeezed. In addition, existing office chairs are usually not intelligent enough and cannot perform shoulder, neck and waist massage according to the user's needs, which cannot effectively relieve fatigue and is very inconvenient to use. Therefore, an ergonomic office chair structure with good fatigue relief effect and its use method are proposed to solve the above problems. Summary of the Invention

[0005] In response to the deficiencies in the prior art, the present invention provides an ergonomic office chair structure with good fatigue-relieving effect and a method for using the same. The structure has the advantage of good fatigue-relieving effect and solves the problem that existing office chairs are usually ordinary chairs that are not ergonomically designed, causing workers to suffer from back pain and fatigue after sitting for a long time, and cannot be adjusted according to the user's body shape, resulting in the user's waist being suspended or over-squeezed. In addition, existing office chairs are usually not intelligent enough and cannot perform shoulder, neck and waist massage according to the needs of the user, thus failing to effectively relieve fatigue and being very inconvenient to use.

[0006] Technical Solution

[0007] To achieve the above-mentioned purpose of achieving a good fatigue-relieving effect, the present invention provides the following technical solution: an ergonomic office chair structure with a good fatigue-relieving effect, comprising an office chair body, a chair back hingedly connected to the right side of the office chair body, a sliding seat provided at the bottom of the office chair body, auxiliary mechanisms provided both inside and outside the office chair body, and an intelligent control system provided inside the office chair body;

[0020] Step 2: The PLC controller drives the motor to start, causing the chair back to rotate and fit the user's back to prevent the waist and back from hanging in the air;

[0021] Step 3: The second electric push rod drives the camera down to the specified height to collect the user's movements and expressions, and uses the expression recognition module and the movement recognition module to identify fatigue expressions, and the fatigue judgment module makes a comprehensive judgment;

[0022] Step 4: When the user is judged to be in a fatigue state, the early warning module issues a warning. At this time, the PLC controller drives the motor to start fine-tuning the chair back to ensure that the user's neck and waist fit closely with the first and second electric massagers. At this time, the PLC controller drives the two-way valve to start, exhausting air through the exhaust pipe to soften the office chair body.

[0023] Step 5: At this time, the PLC controller drives the first electric massager and the second electric massager to massage the user to relieve fatigue. At the same time, the timing module starts timing. When the massage is completed, the fatigue judgment module judges the user's status for the second time.
