First, the sitting state is detected by the sitting detection device 2, the air pressure detection device 3 detects a plurality of actual air pressure data corresponding to each cushion air bag in the air bag device 1, then, the control device 4 determines a plurality of air pressure control signals according to the detected sitting state and each actual air pressure data, and the air path distribution device 5 performs air pressure adjustment on the corresponding cushion air bag in the air bag device 1 according to each air pressure control signal to adjust the sitting posture of the seat. This application can take a seat the actual atmospheric pressure data of state and cushion gasbag through automated inspection to adjust the realization automatically regulated position of sitting according to this to the atmospheric pressure of each cushion gasbag, thereby solve the influence that a position of sitting brought of maintaining for a long time.

In a practical application scenario, when the sitting detection device 2 detects that a person sits on the seat, that is, the sitting state is sitting, the air pressure detection device 3 can detect actual air pressure data of a plurality of cushion airbags, the control device 4 generates corresponding air pressure control signals according to the detected actual air pressure data and sends the corresponding air pressure control signals to the air path distribution device 5, and the air path distribution device 5 adjusts the air pressure of the corresponding cushion airbags according to the air pressure control signals to realize sitting posture adjustment.
It should be noted that, in some embodiments, the air path distribution device 5 is connected to the airbag device 1 and the air pressure detection device 3 through air pipes, so that the air path distribution device 5 can achieve the effect of adjusting the air pressure by adjusting the air in and out of the airbag device 1, and at the same time, the air pressure detection device 3 is convenient to detect the actual air pressure data of the cushion airbag in the airbag device 1. It is understood that the air pressure detecting means 3 is an air pressure sensor.
In some embodiments, when the seating state detected by the seating detection device 2 is seated, the control device 4 compares each actual air pressure data of the cushion airbag with a preset pressure threshold to obtain a magnitude relationship, and generates an air pressure control signal according to the magnitude relationship, so that the subsequent air path distribution device 5 can control the air pressure of the corresponding cushion airbag according to the air pressure control signal. It is understood that the seating detection device 2 is an infrared sensor.
In some embodiments, when the seating state detected by the seating detection device 2 is not seated, the control device 4 controls the cushion airbag to adjust to the initial position, for example, the control device 4 sends a corresponding air pressure control signal to the air path distribution device 5, so that the air path distribution device 5 adjusts the air pressure of the cushion airbag to the initial state according to the air pressure control signal, and the cushion airbag returns to the initial position; or the control device 4 generates a pause adjusting signal to stop adjusting the air pressure inside the cushion air bag, so as to stop adjusting the position of the cushion air bag, and at the moment, the sitting posture adjustment is also stopped.
In some embodiments, the air pressure control signal includes a first control signal, when the seated state is a seated state, and the detected actual air pressure data is smaller than a preset pressure threshold, the control device 4 generates the first control signal and sends the first control signal to the air path distribution device 5, and the air path distribution device 5 increases the air pressure inside the corresponding cushion airbag according to the first control signal. For example, if the control device 4 determines that the air pressure data of the first air bag 111 detected by the air pressure detecting device 3 is smaller than the preset pressure threshold for the first air bag 111, the control device generates and sends a first control signal to the air path distribution device 5, and the air path distribution device 5 increases the air pressure inside the first air bag 111 according to the first control signal to make the air pressure equal to the preset pressure threshold. It should be noted that the air path distribution device 5 adjusts the air pressure inside the cushion airbag to be equal to the corresponding preset pressure threshold, which means that the air pressure is not completely equal, but a deviation within a certain preset range is allowed to exist, so that the air pressure inside the cushion airbag is close to the corresponding preset pressure threshold.
In some embodiments, the sitting posture adjusting system further includes an inflator 6, the inflator 6 is respectively connected to the air path distribution device 5 and the control device 4, the control device 4 generates a first control signal to send to the air path distribution device 5 and simultaneously sends the first control signal to the inflator 6, the inflator 6 controls the corresponding cushion airbag to increase air pressure according to the first control signal, the corresponding cushion airbag is inflated to increase the air pressure inside the cushion airbag, and thus the shape of the cushion airbag is changed, and the sitting posture adjusting effect is achieved. Specifically, when the first control signal is generated by the control device 4 according to the fact that the actual air pressure data inside the lumbar support airbag 12 is smaller than the preset pressure threshold, the inflator 6 inflates the lumbar support airbag 12 according to the first control signal, so that the lumbar cushion moves forward; when the first control signal is generated by the control device 4 according to the fact that the actual air pressure data inside the bottom air bag 11 is smaller than the preset pressure threshold, the inflator 6 inflates the corresponding bottom air bag 11 according to the first control signal, and the bottom cushion moves upwards.

In some embodiments, the air pressure control signal includes a second control signal, when the sitting state is a seated state, and the detected actual air pressure data is greater than the preset pressure threshold, the control device 4 generates the second control signal and sends the second control signal to the air path distribution device 5, and the air path distribution device 5 reduces the air pressure inside the corresponding cushion airbag according to the second control signal. For example, if the control device 4 determines that the air pressure data of the first airbag 111 detected by the air pressure detecting device 3 is greater than the preset pressure threshold for the first airbag 111, the control device generates and sends a second control signal to the air path distribution device 5, and the air path distribution device 5 reduces the air pressure inside the first airbag 111 according to the second control signal so as to make the air pressure equal to the preset pressure threshold. It should be noted that the air path distribution device 5 adjusts the air pressure inside the cushion airbag to be equal to the corresponding preset pressure threshold, which means that the air pressure is not completely equal, but a deviation within a certain preset range is allowed to exist, so that the air pressure inside the cushion airbag is close to the corresponding preset pressure threshold.
In some embodiments, the sitting posture adjusting system further includes an exhaust valve 7, the exhaust valve 7 is respectively connected with the air path distribution device 5 and the control device 4, the control device 4 generates a second control signal to send to the air path distribution device 5 and simultaneously sends the second control signal to the exhaust valve 7, the exhaust valve 7 controls the corresponding cushion airbag to perform air pressure reduction processing according to the second control signal, the gas inside the corresponding cushion airbag is discharged, the air pressure inside the cushion airbag is reduced, the shape of the cushion airbag is changed accordingly, and the sitting posture adjusting effect is achieved. Specifically, when the second control signal is generated by the control device 4 according to the fact that the actual air pressure data inside the lumbar support airbag 12 is larger than the preset pressure threshold, the exhaust valve 7 exhausts the air inside the lumbar support airbag 12 according to the second control signal, so that the lumbar cushion moves backwards; when the second control signal is generated by the control device 4 according to the fact that the actual air pressure data inside the bottom air bag 11 is larger than the preset pressure threshold, the exhaust valve 7 exhausts the air inside the corresponding bottom air bag 11 according to the second control signal, so that the bottom cushion moves downwards.
In some embodiments, when the seated state is seated, the control device 4 compares the magnitude relationship between the actual air pressure data corresponding to each bottom air bag 11 and the corresponding air pressure expected value, which is a random value within the preset air pressure range, every preset period, and generates the air pressure control signal according to the magnitude relationship. In practical application, when the sitting detection device 2 detects that the sitting state is sitting, the control device 4 compares the magnitude relation between the actual air pressure data of the bottom air bags 11 and the expected air pressure value every five minutes, and adjusts the air pressure inside each corresponding bottom air bag 11 according to the magnitude relation, so as to adjust all the bottom air bags 11, thereby realizing the deformation of the bottom cushion and achieving the effect of adjusting the sitting posture. Wherein, atmospheric pressure expected value is the random value of predetermineeing the atmospheric pressure within range, is not the fixed value, every time carries out the comparison, atmospheric pressure expected value will change to this atmospheric pressure of guaranteeing every bottom gasbag 11 after the adjustment is inconsistent, therefore also can take place deformation for the bottom cushion, also consequently can guarantee that the deformation of the bottom cushion after adjusting at every turn is different with the deformation after last adjustment, reaches the purpose of timing automatically regulated position of sitting.
