DETAILED DESCRIPTION

[0051] The present application is further described in detail below with reference to Figs. 1-22.

[0052] As mentioned in the background, to solve the problems in the prior art, the present application proposes a pneumatic massage system. The pneumatic massage system comprises:

[0053] a gas bag assembly 1 and a control assembly 2.

[0054] The air bag assembly 1 comprises a plurality of serially connected twin air bags 11, each of which comprises a body air bag 111 and a serial air bag 112 arranged in communication with the body air bag 111, which can be connected with adjacent twin air bags 11 or non-adjacent twin air bags 11.

[0055] The control assembly 2 comprises an air source 21, a gas distribution valve 22 and a controller 23. The air source 21 inflates the plurality of twin air bags 11 through the gas distribution valve 22; the gas distribution valve 22 is configured to adjust the gas flow state. The controller 23 controls the air source 21 and the gas distribution valve 22 according to a specific inflation and deflation time sequence to sequentially inflate or deflate the plurality of twin air bags 11, and the specific inflation and deflation time sequence should satisfy: the positions of the plurality of twin air bags 11 inflated and lifted can be serially shifted; it is emphasized that the plurality of twin air bags 11 can be non-serially connected in terms of connection mode, but the inflation and deflation time sequence is serial.

[0056] When the driver needs to be massaged due to fatigue, the massage system is started, and the controller 23 controls the air source 21 and the gas distribution valve 22 according to a specific time sequence to sequentially inflate or deflate the plurality of twin air bags 11, so as to realize the pneumatic pressing of the driver side. Through the serial connection mode between the plurality of twin air bags 11, and in cooperation with the specific time sequence preset by the controller 23, the positions of the plurality of twin air bags 11 inflated and lifted can be serially shifted. In this way, the driver side will feel a rolling and coherent massage, thereby improving the massage effect and bringing a better massage experience to the driver.

[0057] Optionally, taking one of the single twin air bags 11 as an example, the twin air bag 11 comprises one body air bag 111 and at least one serial air bag 112, the body air bag 111 and the serial air bag 112 are arranged in the same plane, and the body air bag 111 and the serial air bag 112 are serially connected and directly communicated, both of which belong to an integral molding structure. Of course, the body air bag 111 and the serial air bag 112 can also not be integrally formed, which is determined according to the actual cost and production situation, and is not limited here.

[0058] Optionally, taking one of the single twin air bags 11 as an example, the body air bag 111 and the serial air bag 112 are arranged in the same plane, and the body air bag 111 and the serial air bag 112 are indirectly communicated through the air pipe 3 arranged therebetween.

[0059] Optionally, taking an example of a certain monomer twin gas bag 11 which is provided with only one connection gas bag 112, the body gas bag 111 and the connection gas bag 112 are the same shape and size, and the shapes of the two can be configured to include but not limited to circular, oval, rectangular or spindle, and can be selected according to actual scenarios.

[0060] Optionally, the body gas bag 111 and the connection gas bag 112 can be any one of a single-layer gas bag, a double-layer gas bag or a multi-layer gas bag, and can be selected according to actual scenarios.

[0061] Optionally, the gas source 21 can select any one of a vehicle body gas source, a gas storage tank or a gas pump, and taking the gas pump as an example, the gas pump fills the plurality of twin gas bags 11 with gas through the gas distribution valve 22.

[0062] Optionally, the gas distribution valve 22 includes an air inlet, a gas filling port, a gas discharge port and a valve core, the air inlet is in communication with the gas pump, the gas filling port is in communication with the twin gas bag 11, and the controller 23 is configured to control the movement of the valve core to control the air inlet to be opened and the gas discharge port to be closed, or the air inlet to be closed and the gas discharge port to be opened. It should be noted that the gas distribution valve 22 is a conventional setting in the art, and therefore the specific structure of the gas distribution valve 22 is not shown in the drawing.

[0063] Optionally, based on the different chain states formed by the connection of the plurality of twin gas bags 11, the gas bag assembly 1 can be divided into a chain-shaped gas bag assembly 4, a ring-shaped gas bag assembly 5 and a branch-shaped gas bag assembly 6, and specifically:

[0064] The chain-shaped gas bag assembly 4 includes a straight chain-shaped gas bag assembly 41 and a curved chain-shaped gas bag assembly 42, and the chain shape of the curved chain-shaped gas bag assembly 42 includes but is not limited to V-shaped, U-shaped and S-shaped. Different chain shapes can achieve different massage modes to meet the diversified massage needs of passengers. Taking an example of the connection mode of the connection gas bag 112 and the adjacent twin gas bag 11, the connection relationship of the chain-shaped gas bag assembly 4 is described as follows (for convenience, the plurality of twin gas bags are numbered in order):

[0065] The connection gas bag 112 of the twin gas bag 1 is superimposed with the body gas bag 111 of the twin gas bag 2, the connection gas bag 112 of the twin gas bag 2 is superimposed with the body gas bag 111 of the twin gas bag 3, and so on. The connection gas bag 112 of the twin gas bag N is superimposed with the body gas bag 111 of the twin gas bag N+1. In this way, when the last twin gas bag 11 is inflated and rises, it can pre-lift the connection height of the next twin gas bag 11. In addition, the combination arrangement mode of such connection relationship includes but is not limited to same side arrangement or left-right staggered arrangement.

[0066] The doublet gas bags 11 at the head and tail ends of the chain-shaped gas bag assembly 4 are each provided with a compensation gas bag 113. Specifically, the compensation gas bag 113 at the head end is specifically arranged on the shaft side of the body gas bag 111, and the compensation gas bag 113 at the tail end is specifically arranged on the shaft side of the connecting gas bag 112. The compensation gas bag 113 is configured to keep the lifting height of the gas bag assembly 1 consistent when the lifting height of the gas bag assembly 1 at the lifting position is continuously shifted. The compensation gas bag 113 can be any one of a single-layer gas bag, a double-layer gas bag or a multi-layer gas bag, and can be specifically selected and used according to actual scenarios.

[0067] The dynamic process of the rolling massage of the chain-shaped gas bag assembly 4 is as follows:

[0068] Taking the A→B direction sequence as an example, at t0, the doublet gas bag 1, the doublet gas bag 2 and the doublet gas bag 3 start to be inflated, the connecting gas bag 112 of the doublet gas bag 1 and the body gas bag 111 of the doublet gas bag 2 are overlapped and lifted, the connecting gas bag 112 of the doublet gas bag 2 and the body gas bag 111 of the doublet gas bag 3 are overlapped and lifted, and the connecting gas bag 112 of the doublet gas bag 3 pre-lifts the body gas bag 111 of the doublet gas bag 4;

[0069] At t1, the doublet gas bag 1 starts to be deflated, the doublet gas bag 2 and the doublet gas bag 3 continue to be inflated, the doublet gas bag 4 starts to be inflated, the body gas bag 111 of the doublet gas bag 4 is inflated and overlapped with the lifting height of the connecting gas bag 112 of the doublet gas bag 3, and the connecting gas bag 112 of the doublet gas bag 4 pre-lifts the body gas bag 111 of the doublet gas bag 5;

[0070] At t2, the doublet gas bag 2 starts to be deflated, the doublet gas bag 3 and the doublet gas bag 4 continue to be inflated, the doublet gas bag 5 starts to be inflated, the body gas bag 111 of the doublet gas bag 5 is inflated and overlapped with the lifting height of the connecting gas bag 112 of the doublet gas bag 4, and the connecting gas bag 112 of the doublet gas bag 5 pre-lifts the compensation gas bag 6 at the tail end;

[0071] At t3, the doublet gas bag 3 starts to be deflated, the doublet gas bag 4 and the doublet gas bag 5 continue to be inflated, the compensation gas bag 6 starts to be inflated (the compensation gas bags 6 at the head and tail ends are inflated at the same time), the compensation gas bag 6 at the tail end is inflated and overlapped with the lifting height of the connecting gas bag 112 of the doublet gas bag 5, and the compensation gas bag 6 at the head end is inflated and pre-lifts the body gas bag 111 of the doublet gas bag 1;

[0072] At t4, the doublet gas bag 4 starts to be deflated, the doublet gas bag 5 and the compensation gas bag 6 continue to be inflated, the doublet gas bag 1 starts to be inflated again, the body gas bag 111 of the doublet gas bag 1 is inflated and overlapped with the lifting height of the compensation gas bag 6 at the head end, and the connecting gas bag 112 of the doublet gas bag 1 pre-lifts the body gas bag 111 of the doublet gas bag 2.

[0073] At time t5, the twin air bag 5 starts to deflate, the compensation air bag 6 and the twin air bag 1 continue to inflate, the twin air bag 2 starts to inflate again, the body air bag 111 of the twin air bag 2 is inflated and superimposed with the lifting height of the successive air bag 112 of the twin air bag 1, and the successive air bag 112 of the twin air bag 2 pre-lifts the body air bag 111 of the twin air bag 3;

[0074] At time t6, the timing starts again, and the cycle is repeated to form a continuous rolling massage for the air bag assembly 1.

[0075] Optionally, the chain-shaped air bag assembly 4 also provides a collapsed rolling massage mode, and the massage dynamic process is as follows:

[0076] Taking the A→B direction sequence as an example, at time t0, the twin air bag 2, the twin air bag 3, the twin air bag 4 and the twin air bag 5 start to inflate, and the twin air bag 1 and the compensation air bag 6 are in a deflated state;

[0077] At time t1, the twin air bag 2 starts to deflate (the deflation starts when the twin air bag 1 is deflated to half saturation), the twin air bag 1 is still in a deflated state, the twin air bag 3, the twin air bag 4 and the twin air bag 5 continue to inflate, and the compensation air bag 6 starts to inflate;

[0078] At time t2, the twin air bag 3 starts to deflate (the deflation starts when the twin air bag 2 is deflated to half saturation), the twin air bag 2 is still in a deflated state, the twin air bag 4, the twin air bag 5 and the compensation air bag 6 continue to inflate, and the twin air bag 1 starts to inflate again;

[0079] At time t3, the twin air bag 4 starts to deflate (the deflation starts when the twin air bag 3 is deflated to half saturation), the twin air bag 3 is still in a deflated state, the twin air bag 5, the compensation air bag 6 and the twin air bag 1 continue to inflate, and the twin air bag 2 starts to inflate again;

[0080] At time t4, the twin air bag 5 starts to deflate (the deflation starts when the twin air bag 4 is deflated to half saturation), the twin air bag 4 is still in a deflated state, the compensation air bag 6, the twin air bag 1 and the twin air bag 2 continue to inflate, and the twin air bag 3 starts to inflate again;

[0081] At time t5, the compensation air bag 6 starts to deflate (the deflation starts when the twin air bag 5 is deflated to half saturation), the twin air bag 5 is still in a deflated state, the twin air bag 1, the twin air bag 2 and the twin air bag 3 continue to inflate, and the twin air bag 4 starts to inflate again;

[0082] At time t6, the track t0 is connected, and the timing starts to execute again. This cycle enables the collapsed area formed by the twin air bags 11 in the deflated state to slide continuously, forming a collapsed rolling massage mode.

[0083] Alternatively, the chain-shaped air bag assembly 4 also provides a palm pressure rolling massage mode. For example, the chain-shaped air bag assembly 4 contains two independent chains. The massage dynamic process of the palm pressure rolling massage mode is as follows:

[0084] For example, in the A→B direction sequence, at time t0, the twin air bags 2, 3, 4, and 5 start to inflate, the twin air bag 1 and the compensation air bag 6 are in the deflated state, the connecting air bag 112 of the twin air bag 2 is overlapped with the body air bag 111 of the twin air bag 3, the connecting air bag 112 of the twin air bag 3 is overlapped with the body air bag 111 of the twin air bag 4, and the connecting air bag 112 of the twin air bag 4 is overlapped with the body air bag 111 of the twin air bag 5. At this time, the chain on one side of the air bag assembly 1 forms three highest massage points, and due to the different inflation times, the height and hardness of the twin air bags 11 being connected and lifted are different, forming a feeling similar to palm pressing; after time t1, the lifted position of the twin air bags 11 slides continuously with the timing, preparing for the intervention of palm pressing on the other side chain. The subsequent massage logic is referred to the massage timing diagram.

[0085] Alternatively, the ring-shaped air bag assembly 5 is a closed loop structure formed by at least three connecting twin air bags 11. The ring-shaped rolling massage dynamic process of the ring-shaped air bag assembly 5 is as follows:

[0086] For example, in the A→B→C→A direction sequence, at time t0, the twin air bags 1 and 2 start to inflate, the body air bag 111 of the twin air bag 2 is overlapped with the connecting air bag 112 of the twin air bag 1, and the connecting air bag 112 of the twin air bag 2 is inflated to pre-lift the body air bag 111 of the twin air bag 3. The twin air bags 3 and 4 are in the deflated state.

[0087] At time t1, the twin air bag 1 starts to deflate, the twin air bag 2 continues to inflate, the twin air bag 3 starts to inflate, and the twin air bag 4 is still in the deflated state. The body air bag 111 of the twin air bag 3 is overlapped with the connecting air bag 112 of the twin air bag 2, and the connecting air bag 112 of the twin air bag 3 is inflated to pre-lift the body air bag 111 of the twin air bag 4.

[0088] From time t2, twin airbag 2 begins to deflate, twin airbag 3 continues to inflate, twin airbag 4 begins to inflate, twin airbag 1 remains deflated, the main airbag 111 of twin airbag 4 and the connecting airbag 112 of twin airbag 3 overlap and lift each other up, the connecting airbag 112 of twin airbag 4 inflates and pre-lifts the main airbag 111 of twin airbag 1;

[0089] At time t3, the twin airbag 3 begins to deflate, the twin airbag 4 continues to inflate, the twin airbag 1 begins to inflate again, and the twin airbag 2 remains deflated. The main airbag 111 of the twin airbag 1 and the connecting airbag 112 of the twin airbag 4 overlap and lift each other up. The connecting airbag 112 of the twin airbag 1 pre-lifts the main airbag 111 of the twin airbag 2.

[0090] At time t4, the timing sequence restarts and repeats, causing the annular airbag assembly 5 to form a circular rolling massage.

[0091] Optionally, the branched airbag assembly 6 includes at least one main chain 61 and at least one secondary chain 62 intersecting the main chain 61. The chain shape formed by the connection of the main chain 61 and the secondary chain 62 includes, but is not limited to, a T-shape, a zigzag shape, a cross shape, an "H" shape, and a bridge shape. The bridge-shaped branched airbag assembly 6 includes two independently arranged main chains 61 and at least one secondary chain 62 bridging the two main chains 61. Of course, the bridge-shaped branched airbag assembly 6 may also include three, four, five, or more independently arranged main chains 61, and one, two, three, four, or more secondary chains 62 may be spaced apart between adjacent main chains 61; this is not limited here.

[0092] Optionally, this application proposes a car seat comprising a foam layer 7 and a cover layer 8, as well as the aforementioned pneumatic massage system.

[0093] The airbag assembly 1 is arranged between the foam layer 7 and the cover layer 8. In practical applications, the airbag assembly 1 can be installed on both the backrest and the seat of the car seat. The control assembly 2 can be flexibly arranged in a position away from the occupant's head according to the seat space. By installing the above-mentioned pneumatic massage system in the car seat to massage the occupant, driving fatigue can be relieved.
