Technical Feild
The innovation patent belongs to the technical field of furniture, and particularly relates
to a self-powered intelligent chair.
Background
Nowadays, people's sedentary time gradually increases, which brings a series of health
problems, such as myopia, obesity, varicose veins of the lower extremities, lumbar disc
herniation, and cervical spondylosis. By maintaining a good sitting posture, avoiding sitting
for a long time, and timely exercise, we can avoid the above health problems.
The ergonomic chair can help maintain the user's good sitting posture by reasonably
designing the structure of the seat cushion and the back of the chair, but taking the back of the
chair as an example, in actual work, the user may not lean on the back of the chair. By
integrating a pressure sensor in the seat, the user's sitting posture and sitting time can be
sensed. Based on the integrated embedded system and speaker module, the user can be
reminded to change the sitting posture. At the same time, a small generator is provided in front
of the seat, and the user can rotate the rollers by the feet to provide power for the seat and
exercise at the same time.
Summary of the Invention
The innovation patent proposes a self-powered intelligent chair. The user can use the
rotary pedal at the front of the seat to drive the generator to generate electrical energy while
working, which can help exercise the lower limb muscles. At the same time, the electrical
energy generated by the generator is input into the intelligent chair to supply power for the
included microprocessor, sensor, speaker, and vibration module to realize sitting posture
monitoring, sedentary reminder and massage functions, thereby avoiding health problems
caused by sedentary sitting.

above 40N, it starts timing. The sedentary reminder time can be set to 30 minutes, 45 minutes, 60 minutes, etc., depending on user's needs, when the user's sedentary time is above the set
reminder value, the microprocessor 5 drives the speaker 7 to remind the user that "your
sedentary time has reached 30/40/60 minutes, please pay attention to rest", when the user
ignores the speaker reminder to continue sitting for a long time, the microprocessor 5 drives the first vibration module 8-1 and the second vibration module 8-2 to remind the user to pay
attention to rest and massage the user's thigh and the back muscles to promote blood
circulation; the second pressure sensor 6-2 in the back of the chair is used to monitor the sitting posture, and the threshold can be set to 1ON, when the pressure monitored by the
second pressure sensor 6-2 is abovelON, the micro-processing 5 drives the speaker 8 to
remind the user "please pay attention to sitting position". This innovative patent provides a preferred solution. The microprocessor records the
user's overall sedentary time of the day and of the week. When the user's sedentary time per
day> 6 hours, or a week's sedentary time> 42 hours, the speaker reminds the user that "your sedentary time today is more than 6 hours, please exercise properly" or "your sedentary time of the week is more than 42 hours, please exercise properly". At the same time, the above historical usage information can be transmitted to the mobile phone APP using Bluetooth or
USB cable, which is convenient for the user to grasp the recent sedentary situation so as to reasonably arrange work and rest.
The above embodiments do not limit the innovation patent in any form, and any technical
solution obtained by adopting the form of equivalent replacement or equivalent transformation
falls within the protection scope of the innovation patent.
