It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] like Figures 1 to 5 As shown, this utility model provides a seat pneumatic control system 100, comprising:

[0029] The chair back control module 110 includes a first air tube assembly 111, at least one first controller 112, and a plurality of first pneumatic actuators 113, all mounted on the chair back 200. The first pneumatic actuators 113 are connected to the first controller 112 via the first air tube assembly 111. Understandably, the first controller 112 controls the input or output of gas to the first pneumatic actuators 113 via the first air tube assembly 111, thereby enabling the first pneumatic actuators 113 to perform operations such as support, cushioning, or massage. Specifically, the first pneumatic actuators 113 are located on the side of the chair back 200 facing the user, i.e., on the backrest surface of the seat, facilitating direct application of support, cushioning, or massage operations to the user. The first controller 112 can be located on the side of the chair back 200 away from the user, thus avoiding affecting the user's seating experience. The first air tube assembly 111 can pass through the chair back 200, thereby connecting the first pneumatic actuators 113 and the first controller 112 located on opposite sides of the chair back 200. The number of the first controllers 112 can be set according to the actual situation. If there are multiple first controllers 112, they can communicate with each other, so that the multiple first pneumatic actuators 113 connected to the multiple first controllers 112 can achieve synchronized operation.

[0030] The seat cushion control module 120 includes a second air tube assembly 121, at least one second controller 122, and a plurality of second pneumatic actuators 123, all mounted on the seat cushion 300. The second pneumatic actuators 123 are connected to the second controller 122 via the second air tube assembly 121. Specifically, the second controller 122 controls the input or output of gas to the second pneumatic actuators 123 via the second air tube assembly 121, thereby enabling the second pneumatic actuators 123 to perform operations such as support, cushioning, or massage. The second pneumatic actuators 123 are positioned on the side of the seat cushion 300 facing the user, facilitating direct application of support, cushioning, or massage to the user. The second controller 122 can be positioned on the side of the seat cushion 300 away from the user, thus avoiding affecting the user's riding experience. The second air tube assembly 121 can pass through the seat cushion 300, thereby connecting the second pneumatic actuators 123 and the second controller 122 located on opposite sides of the seat cushion 300. The number of the second controllers 122 can be set according to the actual situation. If there are multiple second controllers 122, they can communicate with each other, so that the multiple second pneumatic actuators 123 connected to the multiple second controllers 122 can achieve synchronized operation.

[0031] The first controller 112 is communicatively connected to the second controller 122. This communication connection enables synchronized and coordinated operation between the backrest control module 110 and the seat cushion control module 120. Understandably, both the first controller 112 and the second controller 122 can be ECUs (electronic control units).

[0032] In this invention, by setting a first controller 112 on the backrest 200 and a second controller 122 on the seat cushion 300, the first pneumatic actuator 113 on the backrest 200 can be connected to the first controller 112 on the backrest 200 via the first air pipe assembly 111, and the second pneumatic actuator 123 on the seat cushion 300 can be connected to the second controller 122 on the seat cushion 300 via the second air pipe assembly 121. This simplifies the arrangement of the seat pneumatic control system 100. Furthermore, even with a large number of pneumatic actuators, complex air pipes are not required, avoiding damage or blockage caused by mutual compression between air pipes. Simultaneously, the communication connection between the first controller 112 and the second controller 122 enables coordinated action control and time synchronization between the first pneumatic actuator 113 and the second pneumatic actuator 123, improving the control effect of the seat pneumatic control system 100 with multiple controllers.

[0033] like Figures 1 to 3 As shown, in one embodiment, the seat pneumatic control system 100 further includes a communication bus 130, through which all the first controllers 112 and all the second controllers 122 are connected. Understandably, the communication bus 130 can be a CAN (Controller Area Network) bus or a LIN (Local Interconnect Network) bus, etc. In this embodiment, all the first controllers 112 and all the second controllers 122 are connected to the communication bus 130 to form a communication network. The topology of the communication network can be a bus topology or a star topology. Since the first controllers 112 and all the second controllers 122 are connected through the communication bus 130, the communication bus 130 can transmit control signals to all the first controllers 112 and all the second controllers 122 to control the actions of each controller. Simultaneously, the communication bus 130 can also be used to transmit synchronization signals, enabling the actions of all the first controllers 112 and all the second controllers 122 to be synchronized in time.

[0034] likeFigure 2 As shown, in one embodiment, the seat pneumatic control system 100 further includes a first main controller 140, which is connected to the communication bus 130. Understandably, the first main controller 140 can be a host computer (e.g., a vehicle infotainment system or on-board computer) or an ECU. In this embodiment, after the first main controller 140 is connected to the communication bus 130, it joins the aforementioned communication network (i.e., the communication network formed by connecting the first controller 112 and the second controller 122 to the communication bus 130). At this time, the first main controller 140 acts as the master node in the communication network, sending communication frames to all first controllers 112 and all second controllers 122 in the communication network. The communication frames include synchronization frames and control frames. The synchronization frames can be sent cyclically according to a preset time interval. After receiving the synchronization frames, the first controllers 112 and 122 can synchronize the time on the communication network. The control frames can be sent according to actual conditions. After receiving the control frames, the first controllers 112 and 122 can perform actions according to the content of the control frames.

[0035] like Figure 3 As shown, in one embodiment, the seat pneumatic control system 100 further includes a second main controller 150, which is communicatively connected to any one of the first controllers 112 or the second controller 122. Understandably, the second main controller 150 can be a host computer. After the second main controller 150 is communicatively connected to any one of the first controllers 112 or the second controller 122, the second main controller 150 can send communication frames to the connected first controller 112 or second controller 122 to achieve coordinated motion control and time synchronization.

The third controller 171 is connected to a communication bus 130. It is understood that the side wing control module can be located on the seat back 200, on the seat cushion 300, or simultaneously on both. The third controller 171 controls the input or output of gas to the third pneumatic actuators via the third air pipe assembly, thereby enabling the third pneumatic actuators to perform operations such as support, cushioning, or massage. Multiple third pneumatic actuators can be respectively disposed on opposite sides of the chair back 200 and / or seat cushion 300 to form a clamping shape for directly performing operations such as pressing on the user. The third controller 171 can be disposed on the side of the chair back 200 and / or seat cushion 300 away from the user to avoid affecting the user's riding experience. The third air tube assembly can be inserted into the chair back 200 and / or seat cushion 300 to connect the third pneumatic actuators and the third controller 171 located on opposite sides of the chair back 200 and / or seat cushion 300, respectively. The number of third controllers 171 can be set according to actual needs. If there are multiple third controllers 171, they are communicatively connected to each other, so that the multiple third pneumatic actuators connected to the multiple third controllers 171 can achieve synchronized operation. The third controller 171 is connected to the communication bus 130 to communicate with the first controller 112 and the second controller 122 through the communication bus 130, so that the side wing control module, the backrest control module 110 and the seat cushion control module 120 can achieve synchronized operation.
