Detailed implementation manners

[0063] The following further illustrates the detailed implementation manners of the present invention with reference to the accompanying drawings. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component, respectively.

[0064] An embodiment of the present invention provides a pneumatic system for a vehicle seat, which includes a left wing and a right wing fixedly connected to the vehicle seat. The left wing includes one or more left airbags, and the right wing includes one or more right airbags. The left airbags are used for the function of flank wrapping and / or steering support, and the right airbags are used for the function of flank wrapping and / or steering support.

[0065] Specifically, each flank includes one or more airbags, which are accommodated in the flank, for example, fixed between the foam and the skeleton inside the flank. At the same time, the airbags are communicated with an air pump, and the air pump supplies air. The airbags can individually realize the function of flank wrapping, or individually realize the function of steering support, or simultaneously realize the functions of flank wrapping and steering support.

[0066] Among them, the flank includes, but is not limited to, a left seat flank fixedly connected to the seat cushion of the vehicle seat, a right seat flank, a left backrest flank fixedly connected to the backrest of the vehicle seat, and a right backrest flank.

[0067] Among them, the function of flank wrapping means that the flanks contract inward or expand outward synchronously to achieve the wrapping of human bodies of different body types.

[0068] The function of steering support means that the left wing or the right wing contracts inward alone to achieve the support for the body roll during vehicle steering.

[0069] For the vehicle seat of the present invention, an airbag capable of being used for the side wing wrapping function or the steering support function is added inside the side wing. Thus, when the vehicle is driving normally, the airbag for the side wing wrapping function wraps the human body to improve comfort. At the same time, when the vehicle is turning, the airbag for the steering support function provides a roll support function for the human body.

[0070] As Figure 1 shown, in one embodiment, the left side wing 8 includes a left first airbag 1 for the side wing wrapping function and a left second airbag 2 for the steering support function, and the right side wing 9 includes a right first airbag 3 for the side wing wrapping function and a right second airbag 4 for the steering support function.

[0071] In this embodiment, each side wing includes two types of airbags, namely a first airbag and a second airbag. The first airbag is used for the side wing wrapping function, and the second airbag is used for the steering support function. Among them, the left side wing may include one or more left first airbags and one or more left second airbags. The right side wing may include one or more right first airbags and one or more right second airbags.

[0072] In one embodiment, the left first airbag 1 is connected in parallel with the right first airbag 3.

[0073] Optionally, the first airbags of the left and right side wings can be connected in parallel to achieve synchronous inflation and deflation.

[0074] In one embodiment, the volume of the left second airbag 2 is smaller than the volume of the left first airbag 1, and the volume of the right second airbag 4 is smaller than the volume of the right first airbag 3.

[0075] Optionally, the volume of the second airbag can be smaller than that of the first airbag to achieve a faster inflation and deflation speed.

[0076] As Figure 4 shown, in one embodiment:

[0077] The left first airbag 1 is connected to an air pump 5 through a left first air pipe 11, and a left first inflation solenoid valve 12 for controlling the on / off of the air pump 5 and the left first airbag 1 is provided on the left first air pipe 11. The left first air pipe 11 is also connected to a left first deflation branch (not shown in the figure) through a left first deflation solenoid valve 13, and the left first deflation solenoid valve 13 controls the on / off of the left first air pipe 11 and the left first deflation branch;

[0078] The second left airbag 2 is connected to the air pump 5 through the second left air tube 21, and a second left inflation solenoid valve 22 for controlling the on / off of the air pump 5 and the second left airbag 2 is provided on the second left air tube 21. The second left air tube 21 is also connected to a second left deflation branch (not shown in the figure) through a second left deflation solenoid valve 23, and the second left deflation solenoid valve 23 controls the on / off of the second left air tube 21 and the second left deflation branch;

[0079] The first right airbag 3 is connected to the air pump 5 through the first right air tube 31, and a first right inflation solenoid valve 32 for controlling the on / off of the air pump 5 and the first right airbag 3 is provided on the first right air tube 31. The first right air tube 31 is also connected to a first right deflation branch (not shown in the figure) through a first right deflation solenoid valve 33, and the first right deflation solenoid valve 33 controls the on / off of the first right air tube 31 and the first right deflation branch;

[0080] The second right airbag 4 is connected to the air pump 5 through the second right air tube 41, and a second right inflation solenoid valve 42 for controlling the on / off of the air pump 5 and the second right airbag 4 is provided on the second right air tube 41. The second right air tube 41 is also connected to a second right deflation branch through a second right deflation solenoid valve 43, and the second right deflation solenoid valve 43 controls the on / off of the second right air tube 41 and the second right deflation branch.

[0081] Specifically, in this embodiment, each wing includes two types of airbags, namely the first airbag and the second airbag. The first airbag is used for the wing wrapping function, and the second airbag is used for the steering support function. Among them, the left wing may include one or more first left airbags and one or more second left airbags. The right wing may include one or more first right airbags and one or more second right airbags.

[0082] The solenoid valve groups of all airbags contain inflation solenoid valves and deflation solenoid valves. When the inflation solenoid valve is opened, the controlled airbag is connected to the air pump 5. When the inflation solenoid valve is closed, the controlled airbag is disconnected from the air pump 5. When the deflation solenoid valve is opened, the controlled airbag deflates through the deflation branch. When the deflation solenoid valve is closed, the controlled airbag stops deflating. At the same time, since multiple airbags are connected to the same air pump, when the inflation solenoid valves of two airbags are opened, the two corresponding airbags will be connected.

[0083] Figure 4 Only one of each type of airbag is shown in the figure. In fact, there can be multiple of each type of airbag, and the same type of airbags can be controlled by the same set of solenoid valve groups or by independent solenoid valve groups.

[0084] In some embodiments, the solenoid valve groups of all airbags are equipped with air pressure sensors to monitor the air pressure of each airbag in real time;

[0085] Optionally, the volume of the second airbag can be smaller than that of the first airbag to achieve a faster inflation and deflation speed.

[0086] As Figure 2 shown, in one of the embodiments, the left wing 8 includes a left third airbag 6 for wing wrapping function and steering support function, and the right wing 9 includes a right third airbag 7 for wing wrapping function and steering support function.

[0087] In this embodiment, both the left and right wings are composed of a type of third airbag, which is used for both wing wrapping function and steering support function.

[0088] In some embodiments, the left third airbag and the right third airbag are respectively connected to the air pump through air pipes, and the air pump inflates and deflates the left third airbag or the right third airbag respectively to achieve the wing wrapping function and the steering support function.

[0089] Specifically, first inflate and deflate the left third airbag and the right third airbag to a certain wing wrapping position. After receiving the steering support entry instruction, the corresponding airbag is inflated to a certain steering support position. After receiving the steering support exit instruction, the airbag is deflated back to the wing wrapping position. Among them, the steering support position and the wing wrapping position are the heights of the airbag. The height of the airbag in the steering support position is greater than that in the wing wrapping position.

[0090] In some embodiments, the wing wrapping position and the steering support position of the airbag can be set by means of sensors, timers, etc.

[0091] As Figure 3 shown, in one of the embodiments, the left third airbag 6 is respectively connected to the air pump through a left third air pipe 61 and a left fourth air pipe 62, and the right third airbag 7 is respectively connected to the air pump through a right third air pipe 71 and a right fourth air pipe 72.

[0092] Specifically, in this embodiment, both the left and right wings are composed of a type of third airbag. The third airbag is connected to two air pipes at the same time. That is, the left third airbag 6 is respectively connected to the air pump through the left third air pipe 61 and the left fourth air pipe 62, and the right third airbag 7 is respectively connected to the air pump through the right third air pipe 71 and the right fourth air pipe 72. Among them, the left third air pipe 61 and the right third air pipe 71 are used for the wing wrapping function, and the left fourth air pipe 62 and the right fourth air pipe 72 are used for the steering support function.

[0093] Among them, the left third airbag 6 and the right third airbag 7 are not in parallel and are inflated and deflated independently.

[0094] In some embodiments, the fourth left trachea and the fourth right trachea can be connected to a high-flow gas source to achieve a faster inflation speed.

[0095] Such as Figure 5 As shown in the flowchart of the working process of a pneumatic control method for a vehicle seat pneumatic system as described above in an embodiment of the present invention, it includes:

[0096] Step S501: Inflate and deflate the left airbag for the flank wrapping function and the right airbag for the flank wrapping function to the flank wrapping position.

[0097] Step S502: In response to the steering support function entry instruction, inflate the left airbag or the right airbag for the steering support function corresponding to the steering support function entry instruction to the steering support position.

[0098] Step S503: In response to the steering support function exit instruction, deflate the left airbag or the right airbag for the steering support function that is inflated to the steering support position.

[0099] Specifically, the present invention can be applied to an electronic device with processing capabilities, such as a vehicle controller. For example, the electronic control unit (ECU) of a vehicle.

[0100] Specifically, first execute step S501 to inflate and deflate the left airbag for the flank wrapping function and the right airbag for the flank wrapping function to the flank wrapping position.

[0101] Among them, the flank wrapping position refers to a preset height of the airbag. At this height, the flanks will achieve wrapping of the human body. Specifically, by inflating and deflating the airbag, the left and right flanks can be synchronously contracted inward or expanded outward to achieve wrapping of human bodies of different body types.

[0102] In some embodiments, it further includes: obtaining occupant body type information and determining the corresponding flank wrapping position according to the occupant body type information.

[0103] The occupant body type information can be captured by an in-vehicle camera, or determined by sensors on the seat, or input by the occupant himself / herself about his / her body type information.

[0104] Then when the vehicle is turning, a steering support function entry instruction is generated, triggering the execution of step S502. In response to the steering support function entry instruction, the left airbag or the right airbag for the steering support function corresponding to the steering support function entry instruction is inflated to the steering support position.

[0105] Specifically, vehicle steering can be detected by various steering sensors. Then, when the vehicle is steering, a steering support function entry instruction is generated to trigger the execution of step S502. The steering support function entry instruction includes a left steering support function entry instruction and a right steering support function entry instruction. When the vehicle turns left and triggers the left steering support function entry instruction, the left airbag for the steering support function is inflated to the steering support position. When the vehicle turns right and triggers the right steering support function entry instruction, the right airbag for the steering support function is inflated to the steering support position.

[0106] Among them, the steering support position refers to another preset height of the airbag. At this height, the side wings will support the body roll when the vehicle is steering. Specifically, by inflating and deflating the airbag, the left and right side wings can be individually contracted inward to achieve wrapping of human bodies of different body types. Among them, the direction in which the airbag height increases is the direction in which the side wings contract inward.

[0107] In one embodiment, the airbag height at the steering support position is greater than the airbag height at the side wing wrapping position.

[0108] Then, when the vehicle returns to straight and exits the steering, a steering support function exit instruction is generated to trigger the execution of step S503. In response to the steering support function exit instruction, the left airbag or the right airbag for the steering support function that is inflated to the steering support position is deflated.

[0109] Specifically, when the vehicle exits the steering, the left airbag or the right airbag for the steering support function that was previously inflated to the steering support position is deflated.

[0110] On the one hand, the present invention inflates and deflates the airbag for the side wing wrapping function to the side wing wrapping position, and on the other hand, by responding to the steering support function, it controls the airbag for the steering support function to be inflated to the steering support position when the vehicle is steering, so as to simultaneously realize the side wing wrapping function and the steering support function of the seat side wings.

[0111] In one embodiment, the left side wing includes a left first airbag for the side wing wrapping function and a left second airbag for the steering support function, and the right side wing includes a right first airbag for the side wing wrapping function and a right second airbag for the steering support function;

[0183] The third airbag is first inflated and deflated to a certain flank wrapping position;

[0184] After receiving the left steering support entry instruction, the left third airbag is inflated to a certain steering support position;
