The first pressure sensing module 16 includes a plurality of first pressure sensing units 161, and the second pressure sensing module 17 includes a plurality of second pressure sensing units 171.

Likewise, when the included angle between the seat module 11 and the back support module 13 of the chair device 1 is less than a predetermined angle, the control module 18 adjusts the plurality of first pressure adjustment units 141 of the first pressure adjustment module 14 in the seat module 11 and the plurality of second pressure adjustment units 151 of the second pressure adjustment module 15 in the back support module 13 separately. In this case, the control module 18 mainly adjusts the plurality of first pressure adjustment units 141 of the first pressure adjustment module 14 in the seat module 11, so as to improve user experience.


Moreover, a time measurement module 24 of the chair device 1 is a timer, and is electrically connected to the control module 18. After receiving the plurality of first sensed pressure signals from the first pressure sensing module 16 and the plurality of second sensed pressure signals from the second pressure sensing module 17 for a predetermined period of time, the control module 18 provides a plurality of pressure adjustment signals to the plurality of first pressure adjustment units 141 of the first pressure adjustment module 14 and the plurality of second pressure adjustment units 151 of the second pressure adjustment module 15, so as to adjust pressure values provided by the plurality of first pressure adjustment units 141 and the plurality of second pressure adjustment units 151 onto the seat module 11 and the back support module 13, respectively.

When the included angle θ is greater than the predetermined angle, the control module 18 simultaneously controls the plurality of first pressure adjustment units 141 of the first pressure adjustment module 14 and the plurality of second pressure adjustment units 151 of the second pressure adjustment module 15. That is, when the included angle θ is greater than the predetermined angle, the control module 18 determines that the chair device 1 is presently in a chair device status, and the user on the chair device 1 at this time should be lying on the chair device 1. Therefore, the control module 18 simultaneously controls the plurality of first pressure adjustment units 141 of the first pressure adjustment module 14 and the plurality of second pressure adjustment units 151 of the second pressure adjustment module 15, so that the chair device 1 in this case has a pressure adjustment function and can be adjusted in terms of pressure. In this case, the control module 18 may specifically adjust the pressure of the multiple adjacent first pressure adjustment units 141 and second pressure adjustment units 151 (corresponding to the user's waist and back), so as to enhance the support for the user's waist and back and to further improve user experience.

Referring to FIG. 12, description is made below by using the first pressure adjustment module 14″ as an example. The status of the second pressure adjustment module 15″ is similar to that of the first pressure adjustment module 14″, and will not be reiterated herein. FIG. 12 is a schematic view showing that a plurality of spherical objects is disposed on the plurality of airbag units 14A of the pressure adjustment module 14″.


This embodiment involves two types of spherical objects, one of which being a big first spherical object 14A1 and the other one being a small second spherical object 14A2. The big first spherical objects 14A1 are disposed in gaps between the airbag units 14A, and the small second spherical objects 14A2 are disposed on the surfaces of the airbag units 14A. The first spherical objects 14A1 and the second spherical objects 14A2 are both connected in series via a steel wire or plastic wire, so that the first spherical objects 14A1 and the second spherical objects 14A2 can be disposed on the pressure adjustment module 14″. The first spherical objects 14A1 and the second spherical objects 14A2 are steel beads, ceramic beads, plastic beads, or the like, and are in contact with the comfortable seat material layer 110A in a point contact mode.


As shown in FIG. 12, the first spherical objects 14A1 and the second spherical objects 14A2 in this embodiment are both arranged in a matrix, and may be arranged in the shape of a triangle, quadrangle, hexagon, or polygon in other embodiments.


In this embodiment, the sensor module 20 is mainly used to detect first environmental parameters of the seat module 11 or second environmental parameters of the seat module 11 and the back support module 13.


When the included angle θ between the seat module 11 and the back support module 13 is less than the predetermined angle, the sensor module 20 detects the first environmental parameters of the seat module 11.


When the included angle θ between the seat module 11 and the back support module 13 is greater than the predetermined angle, the sensor module 20 detects the second environmental parameters of the seat module 11 and the back support module 13.


The sensor module 20 includes at least a gyro sensor or a vibration sensor. Mattress environmental parameters include at least a vibration status of a mattress module 10.


In addition, the sensor module 20 further includes a temperature sensor or a humidity sensor used to detect the temperature or humidity of the surface of the mattress module.


The sensor module 20 may further include an image sensor, an infrared sensor, a laser ranging sensor, an optical sensor, an olfactory gas sensor, or a weight sensor.


The comfort level analysis module 21 receives the first environmental parameters, the second environmental parameters, the plurality of first sensed pressure signals, and the plurality of second sensed pressure signals from the sensor module 20, so as to determine a comfort level parameter when a user sits in the chair device 1. In this embodiment, the comfort level analysis module 21 uses software for analysis, and may also use hardware or firmware in other embodiments.


In other embodiments, the chair device 1 may also use an optical sensor (not shown in the figure) of the sensor module 20 to detect the comfort level parameter of the user. When the user sits comfortably, his/her body movements are more stable, and there will be fewer movements. Therefore, based on such a feature, the designer may use the vibration sensor, gyro sensor, or optical sensor to detect whether there is constant movement of the user's body when being in the chair device 1, so as to further determine the comfort level parameter when the user sits in the chair device 1.


That is, when the included angle θ between the seat module 11 and the back support module 13 is less than a predetermined angle, the plurality of first pressure sensing units 161 of the first pressure sensing module 16 in the seat module 11 detect a pressure value which is applied by the user on the comfortable seat material layer 110A of the seat module 11, and transmit sensed pressure signals obtained after detection to the control module 18. The control module 18 then transmits these first sensed pressure signals to the comfort level analysis module 21. In addition, the first environmental parameters detected by the sensor module 20 are also transmitted to the comfort level analysis module 21 for analysis.


The comfort level analysis module 21 first makes analysis according to the first environmental parameters. When a vibration status in the first environmental parameters is greater than a first vibration default value, it is determined that the comfort level is low. Further, the comfort level analysis module 21 analyzes the plurality of first sensed pressure signals, and searches for a region that has a high pressure value. When a maximum pressure value of a region is greater than N times of a surrounding pressure value, the comfort level analysis module 21 provides a low-comfort pressure adjustment signal to the control module 18, so that the control module 18 adjusts corresponding pressure adjustment units 121 of the pressure adjustment module 12 to reduce a pressure difference value of a region that has a large pressure difference. N is greater than or equal to 1, and is a rational number. That is, the control module 18 adjusts the region that has a large pressure difference in the sensed pressure signals according to the low-comfort pressure adjustment signal. Afterwards, the comfort level analysis module may continuously monitor a lying status of the user according to the mattress environmental parameters.


That is, when the included angle θ between the seat module 11 and the back support module 13 is greater than the predetermined angle, the user should be in the chair device 1 in a lying down position in this case. The plurality of first pressure sensing units 161 of the first pressure sensing module 16 in the seat module 11 detects a pressure value which is applied by the user on the comfortable back-support material layer 110A of the back support module 13, and transmits sensed pressure signals obtained after detection to the control module 18. The plurality of second pressure sensing units 171 of the second pressure sensing module 17 in the back support module 13 detects a pressure value which is applied by the user on the comfortable back-support material layer 130A of the back support module 13, and transmits second sensed pressure signals obtained after detection to the control module 18.


The control module 18 transmits these first sensed pressure signals and second sensed pressure signals to the comfort level analysis module 21. In addition, the second environmental parameters detected by the sensor module 20 are also transmitted to the comfort level analysis module 21 for analysis.


The comfort level analysis module 21 first makes analysis according to the first environmental parameters. When a vibration status in the first environmental parameters is greater than a first vibration default value, it is determined that the comfort level is low. Further, the comfort level analysis module 21 analyzes the plurality of first sensed pressure signals, and searches for a region that has a high pressure value. When a maximum pressure value of a region is greater than N times of a surrounding pressure value, the comfort level analysis module 21 provides a low-comfort pressure adjustment signal to the control module 18, so that the control module 18 adjusts corresponding pressure adjustment units 121 of the pressure adjustment module 12 to reduce a pressure difference value of a region that has a large pressure difference. N is greater than or equal to 1 and is a rational number. That is, the control module 18 adjusts the region that has a large pressure difference in the sensed pressure signals according to the low-comfort pressure adjustment signal. Afterwards, the comfort level analysis module may continuously monitor a lying status of the user according to the mattress environmental parameters.


The chair device 1 may be communicatively connected to a server 9 or a mobile device 8 via a communication module 22. The user may be communicatively connected to the communication module 22 in the chair device 1 via an application program (APP) in the mobile device 9, so as to send a pressure adjustment signal for pressure adjustment.


In this embodiment, the communication module 22 includes a wired communication unit (not shown in the figure) and a wireless communication unit (not shown in the figure). The wired communication unit (not shown in the figure) may also be independently disposed so as to establish a communicative connection with the server 9, and to receive a control signal from the server 9 or data in a database (not shown in the figure).

When the chair device 1 of the present disclosure is mounted in a movable carrier VH, the first pressure adjustment module 14 in the seat module 11 and the second pressure adjustment module 15 in the back support module 13 of the chair device 1 are continuously on standby.


When the movable carrier VH receives an impact, the control module 18 may adjust and control the first pressure adjustment module 14 and the second pressure adjustment module 15 to disperse the impact force. The micro motors in FIGS. 7 to 10 retract the stroke to the minimum, that is, retract towards the seat propping material layer 110B and the back support propping material layer 130B. In this way, the impact force on the user can be dispersed through the plurality of first pressure adjustment units 141 and the plurality of second pressure adjustment units 151, so as to reduce an impact injury to the user's body. The movable carrier VH may be a car, a van, a sports car, a truck, a bus, a train, or an airplane.

Referring to FIG. 32, FIG. 32 is a schematic view showing that a plurality of spherical objects is disposed on the plurality of airbag units 32A of the pressure adjustment module 32′.


This embodiment involves two types of spherical objects, one of which being a big first spherical object 32A1 and the other one being a small second spherical object 32A2. The big first spherical objects 32A1 are disposed in gaps between the airbag units 32A, and the small second spherical objects 32A2 are disposed on the surfaces of the airbag units 32A.

In this embodiment, the sensor module 34 is mainly used to detect mattress environmental parameters of the mattress module 30. The sensor module 34 includes at least a gyro sensor or a vibration sensor. The mattress environmental parameters include at least a vibration status of a mattress module 30.


In addition, the sensor module 34 may further include a temperature sensor or a humidity sensor used to detect the temperature or humidity of the surface of the mattress module.


The sensor module 34 may further include an image sensor, an infrared sensor, a laser ranging sensor, an optical sensor, an olfactory gas sensor, or a weight sensor.


The comfort level analysis module 36 receives the mattress environmental parameters from the sensor module 34 and the plurality of sensed pressure signals from the plurality of pressure sensing units 331 of the pressure sensing module 33, so as to determine a comfort level when the user lies on the mattress device 3.


That is, when the user lies on the mattress device 3, the plurality of pressure sensing units 331 of the pressure sensing module 33 detects a pressure value which is applied by the user on the comfortable material layer 301 of the mattress module 30, and transmits sensed pressure signals obtained after detection to the control module 30. The control module 30 then transmits these sensed pressure signals to the comfort level analysis module 36. In addition, the mattress environmental parameters detected by the sensor module 14 are also transmitted to the comfort level analysis module 36 for analysis.


The comfort level analysis module 36 first makes analysis according to the mattress environmental parameters. When a vibration status in the mattress environmental parameters is greater than a vibration default value, it is determined that the comfort level is low. Further, the comfort level analysis module 36 analyzes the plurality of sensed pressure signals, and searches for a region that has a high pressure value. When a maximum pressure value of a region is greater than N times of a surrounding pressure value, the comfort level analysis module 36 provides a low-comfort pressure adjustment signal to the control module 30, so that the control module 30 adjusts corresponding pressure adjustment units 321 of the pressure adjustment module 32 to reduce a pressure difference value of a region that has a large pressure difference. N is greater than or equal to 1, and is a rational number. That is, the control module 10 adjusts the region that has a large pressure difference in the sensed pressure signals according to the low-comfort pressure adjustment signal. Afterwards, the comfort level analysis module may continuously monitor a lying status of the user according to the mattress environmental parameters.

Moreover, the first bed body raising module 37 and the second bed body raising module 38 are electrically connected to the control module 31, so as to receive a bed body raising signal from the control module 31.


In this embodiment, after the user lies down for a period of time, the control module 31 may send a bed body raising signal to the first bed body raising module 37, so as to increase the height of the first bed body raising module 37. Thus, the first mattress unit 305 of the mattress module 30 is raised from a first height D1 to a second height D2 to form a tilted curve, so that the user can turn over in this case. When detecting a sensed pressure distribution information that indicates the user has turned over, the control module 11 sends a reply signal to the first bed body raising module 17, so as to restore the first bed body raising module 17 to the first height D1. In this way, the mattress module 30 returns to a flat state. The second height D2 can be changed, and is greater than the first height D1.


Moreover, the mattress device 3 further includes a time measurement module 39 which is electrically connected to the control module 31 and is a timer. After receiving the plurality of sensed pressure signals from the pressure sensing module 33 for a predetermined period of time, the control module 31 provides a plurality of pressure adjustment signals to the plurality of pressure adjustment units 321 of the pressure adjustment module 32, so as to adjust pressure values supplied by the pressure adjustment units 321 to the mattress module 30. The predetermined time may be 5 or 10 minutes, and be set by the user personally.


The mattress device 3 further includes a communication module 40, which is electrically connected to the control module 31.


The mattress device 3 may be communicatively connected to a server 9 or a mobile device 8 via the communication module 20.
