Background technique

With the development of the times and the progress of society, people's work is increasingly dependent on computers, so there are more and more workers in the office. However, workers in the office are usually sedentary. Studies in the medical field have shown that prolonged sitting can easily lead to skeletal diseases such as lumbar disc herniation, spine deformation, and shoulder and neck stiffness, especially when the sitting posture is not standard enough. Will accelerate the induction of related diseases. For example, long-term sitting with legs crossed can easily lead to diseases such as spinal deformity.

At present, the widely used office chairs only have the basic functions of a chair. Therefore, most office workers put a cushion between the backrest of the office chair and the waist of the seated person in order to enhance the support of the waist. However, the supporting force of the cushion is relatively limited, it can only share part of the pressure on the waist, and cannot achieve the effect of correcting the human sitting posture. In addition, the existing office chair cannot limit the sitting time of the seated person, and the seated person is likely to remain in a sitting state for a long time because of too much work and forgetting the time, which is not conducive to the personal health of the seated person.

The lumbar support frame 22 and the scapula support frame 23 are both located on one side of the main support plate 21 and connected to the main support plate 21; the lumbar support frame 22 and The shoulder blade support frame 23 can support the lumbar spine and shoulder blades of the seated person, and the seated person can completely lean the waist and back on the lumbar spine support frame 22 and the shoulder blade support frame 23. One end of the main support plate 21 is fixedly connected to the cushion 1, a lumbar spine mesh pressure sensor group 221 is provided in the lumbar support frame 22, and a scapular mesh pressure sensor group 231 is provided in the scapular support frame 23. The armrests 3 are located on both sides of the seat cushion 1. The supporting leg 4 and the armrest 3 are arranged opposite to the seat cushion 1, and the supporting leg 4 and the seat cushion 1 are fixedly connected. The supporting leg 4 may be a fixed supporting leg as shown in FIG. 1, or a pulley may be installed to realize free sliding, which is not specifically limited in this application. The alarm device 5 is installed on the armrest 3, and can be embedded on the side of the armrest 3 facing upward. The timer 6 is located on the side of the main support board 21 away from the lumbar support frame 22, and the controller 7 is located on the side of the main support board 21 away from the lumbar support frame 22. The controller 7 is electrically connected to the timer 6, the alarm device 5, the cushion mesh pressure sensor group 11, the lumbar vertebra mesh pressure sensor group 221, and the scapular mesh pressure sensor group 231 (the electrical connection cable is not shown in Figure 2) . The seat cushion mesh pressure sensor group 11, the lumbar vertebra mesh pressure sensor group 221, and the scapular mesh pressure sensor group 231 are used to sense the pressure exerted by the seated person on the seat cushion 1, the lumbar support frame 22, and the shoulder blade support frame 23, respectively. The mesh pressure sensor group 11, the lumbar spine mesh pressure sensor group 221, and the scapular mesh pressure sensor group 231 are all grid pressure sensor groups constructed from multiple pressure sensors. The grid density of the grid pressure sensor group It can be designed according to specific needs and is not specifically limited in this application; the cushion mesh pressure sensor group 11, the lumbar vertebra mesh pressure sensor group 221, and the scapular mesh pressure sensor group 231 send the sensed pressure value to the controller 7 in real time.

With reference to Figures 1 and 2, the working process of the office chair capable of correcting sitting posture provided by this embodiment is briefly described as follows:

When a person sits on an office chair with a correctable sitting posture provided in this embodiment, the lumbar spine of the seated person can rest on the lumbar support frame 22, the shoulder blades of the seated person can rest on the shoulder blade support frame 23, or A related control program is written in the controller 7, and when the seated person is seated in a standard sitting posture, both the lumbar spine network pressure sensor group 221 and the shoulder blade network pressure sensor group 231 can sense a certain pressure. When the sitting posture of the seated person becomes non-standard, such as a hunchback, the pressure sensed by the scapular mesh pressure sensor group 231 will be greatly reduced, and the pressure sensed by the lumbar mesh pressure sensor group 221 will increase to a certain extent. , The timer 6 counts the pressure change; when the pressure decrease sensed by the scapular mesh pressure sensor group 231 exceeds the first preset value and lasts for more than the first set time period, at the same time, the lumbar mesh pressure sensor When the pressure increase sensed by group 221 exceeds the second preset value and lasts for more than the first preset time period, the controller 7 can determine that the sitting posture of the seated person is in a hump state. At this time, the controller 7 sends an alarm to the alarm device. 5 Send out the sitting posture alarm instruction, and the alarm device 5 indicates the corresponding warning information. For another example, when a seated person lifts his legs, the pressure distribution sensed by the seat cushion mesh pressure sensor group 11 will change. When the seat cushion mesh pressure sensor group 11 detects a pressure distribution change area that exceeds the preset area and continues When the second preset time period is longer than, the controller 7 can determine that the sitting posture of the seated person is in a state of jogging. At this time, the controller 7 sends a sitting posture warning instruction to the alarm device 5, and the alarm device 5 indicates corresponding warning information. In addition, the controller 7 can also determine whether the sitting posture of the seated person is standard by monitoring changes in the pressure distribution of the lumbar spine mesh pressure sensor group 221 and the scapular mesh pressure sensor group 231. For another example, the timer 6 can also count the time that the seated person sits on the office chair. When the seated person sits on the office chair for more than the third preset time period, the controller 7 can determine The seated person takes too long to sit, and the seated person needs to get up and move for good health. At this time, the controller 7 sends a sedentary alarm instruction to the alarm device 5, and the alarm device 5 indicates corresponding warning information. The timing rule for sedentary sitting can be set as follows: when the time when the pressure value sensed by the cushion mesh pressure sensor group 11 reaches zero reaches the fourth preset time period, the timer 6 is in the cushion mesh pressure sensor group 11 Re-measure the time after the pressure is sensed again. The first preset value, the second preset value, the preset area, the first preset time period, the second preset time period, the third preset time period and the fourth preset time period can all be based on the occupant's Weight, figure, and specific needs are set accordingly. The third preset time period can usually be set to 1 hour, and the fourth preset time period can be set to 5 minutes or 10 minutes, which can flexibly match different seated people. Body shape and personal habits enhance the applicability of the office chair provided in the embodiments of the present application.

The alarm device 5 may include one or more of a voice alarm, a light alarm, and a display, so that the warning information may be voice, indicator light, and display text or image. The voice alarm can send out corresponding warning voices, for example, "You are hunched, please sit upright", "You have your legs up, please sit down", "You should get up and exercise", etc., not listed here. The light alarm can cooperate with the corresponding warning light. A display can also be installed on the armrest 3, and when the alarm device 5 receives an alarm instruction, the corresponding warning text or image can be displayed on the display.
