[0004] In the related art, the support airbag is inflated to lift up the massage airbag. During this process, the massage airbag will sway and shake, causing the massage airbag to deviate from the ideal massage position, thereby affecting the massage effect and giving the occupants a poor massage experience.

When the support air bag is inflated, the limit assembly will axially pull the support air bag to form a local depression on the surface of the support air bag, and the massage air bag is located in the local depression; the control assembly includes an air source, an air distribution valve group and a controller, the air source inflates the air bag assembly through the air distribution valve group; the air source is used to adjust the gas flow state; the controller controls the action of the air source and the air distribution valve group to inflate or deflate the air bag assembly.

[0007] Furthermore, the limiting assembly is a tensioning belt made of a flexible material, and the tensioning belt is fixedly installed between the upper film and the lower film of the supporting air bag. The number of the tensioning belts is consistent with the number of the massage air bags and corresponds one-to-one with the massage air bags. When the supporting air bags are inflated and bulged, a pit-shaped depression will be formed on their surface after being pulled by the tensioning belt.

[0008] Furthermore, the support airbag is configured as an annular airbag, a plurality of the massage airbags are arranged in an enclosed manner at a position closer to the central axis of the support airbag, and a corresponding plurality of the tensioning belts are also arranged at a position closer to the central axis of the support airbag.

[0009] Furthermore, the support air bag is configured as an annular air bag, and the limiting assembly is an annular tension belt made of flexible material. The annular tension belt is fixedly installed between the upper film and the lower film of the support air bag, and divides the support air bag into two chambers. When the support air bag is inflated and bulged, an annular depression will be formed on its surface by being pulled by the annular tension belt.

[0010] Furthermore, the plurality of massage air bags are arranged in an enclosed manner at positions closer to the central axis of the support air bag, and the corresponding annular tension belts are also arranged at positions closer to the central axis of the support air bag.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-Figure 10 Provide further details.

[0030] Example 1

[0031] As mentioned in the background technology, in view of the problems in the prior art, the present application proposes a pneumatic massage system for enhancing massage stability. The pneumatic massage system comprises:

[0032] Air bag assembly 1, limit assembly 2 and control assembly 3;

[0033] The airbag assembly 1 includes a support airbag 11 and a plurality of massage airbags 12 arranged around the support airbag 11; the limit assembly 2 is arranged in the support airbag 11 and corresponds to the massage airbag 12, and the limit assembly 2 has an elastic deformation function. When the support airbag 11 is inflated, the limit assembly 2 will axially pull the support airbag 11, so that a local depression 13 is formed on the surface of the support airbag 11, and the massage airbag 12 is located in the local depression 13;

[0034] The control assembly 3 includes an air source 31, an air distribution valve group 32 and a controller 33. The air source 31 inflates the airbag assembly 1 through the air distribution valve group 32; the air source 31 is used to adjust the gas flow state; the controller 33 controls the operation of the air source 31 and the air distribution valve group 32 to inflate or deflate the airbag assembly 1.

[0035] When the occupant needs a massage due to driving fatigue, the massage system is started, and the controller 33 controls the air source 31 and the air distribution valve to inflate or deflate the support air bag 11 and the massage air bag 12 to achieve the starting pressure on the occupant side. During this process, when the support air bag 11 is inflated, the limit assembly 2 will axially pull the support air bag 11 to form a local depression 13 on the surface of the support air bag 11, and the massage air bag 12 is located in the local depression 13. This local depression 13 can play a stable supporting role for the massage air bag 12, avoiding the massage air bag 12 from swaying, shaking, and dispersing and deviating during the process of being lifted, so that the massage air bag 12 can perform massage more stably and concentratedly, improve the massage effect, and thus bring a better massage experience to the occupant.

[0036] In a preferred embodiment, the air source 31 can be any one of a vehicle body air source 31 , an air tank or an air pump. Taking the air pump as an example, the air pump inflates the massage air bag 12 and the support air bag 11 through the air distribution valve group 32 .

[0037] In a preferred embodiment, the air distribution valve group 32 includes an air inlet 321, an inflation port 322, an air deflation port 323 and a valve core 324. The air inlet 321 is connected to the air pump, and the inflation port 322 is connected to the support air bag 11 and the massage air bag 12. The controller 33 is used to control the movement of the valve core 324 to achieve control of the opening of the air inlet 321 and the closing of the air deflation port 323, or the closing of the air inlet 321 and the opening of the air deflation port 323. It should be noted that the air distribution valve group 32 is a conventional setting in this field, so the attached drawings do not provide a clear diagram of the specific structure of the air distribution valve group 32.

[0038] In a preferred embodiment, the limiting assembly 2 is a tensioning belt 21 made of a flexible material, and the tensioning belt 21 is fixedly installed between the upper film and the lower film of the supporting air bag 11, specifically connected and fixed by welding. The number of the tensioning belts 21 is consistent with the number of the massage air bags 12 and corresponds to the massage air bags 12 one by one. When the supporting air bag 11 is inflated and bulged, a pit-shaped depression 4 is formed on its surface by pulling the tensioning belt 21. The massage air bag 12 is located in the pit-shaped depression 4. The pit-shaped depression 4 can play a stable supporting role for the massage air bag 12, thereby preventing the massage air bag 12 from swaying, shaking, and deviating during the process of being lifted up.

[0039] It should also be noted that the tensioning band 21 itself has an elastic deformation function. More specifically, the tensioning band 21 is tough, that is, the tensioning band 21 will be axially stretched as the support air bag 11 bulges. Specifically, the tensioning band 21 can be axially stretched or axially deformed, which mainly occurs when the support air bag 11 is close to saturation or is completely saturated. When the tensioning band 21 is stretched, the reaction force of the tensioning band 21 on the support air bag 11 is regarded as the greater force. Under this reaction force, the tensioning band 21 will axially pull the support air bag 11. The selection of the tensioning band 21 can be targeted according to actual needs.

[0040] In a preferred embodiment, the support air bag 11 is configured as an annular air bag, and the plurality of massage air bags 12 are enclosed and arranged at a position closer to the central axis of the support air bag 11. The corresponding plurality of tension belts 21 are also arranged at a position closer to the central axis of the support air bag 11. Each tension belt 21 corresponds to a massage air bag 12. Through this arrangement, the plurality of massage air bags 12 are more inclined toward the direction closer to the central axis of the support air bag 11 while being stably supported by the pit-shaped recessed portion 4, so that the plurality of massage air bags 12 can be more gathered and concentrated, thereby providing a better massage effect. It should also be noted that the size of the massage air bag 12 needs to be accurately selected according to actual needs to avoid interference between the air bags.

[0041] In a preferred embodiment, the support airbag 11 is configured as an annular airbag, and the limiting assembly 2 is an annular tension belt 5 made of a flexible material, the annular tension belt 5 is coaxially arranged with the support airbag 11, and the annular tension belt 5 is fixedly installed between the upper membrane and the lower membrane of the support airbag 11, specifically connected and fixed by welding, the annular tension belt 5 divides the support airbag 11 into two chambers (the two chambers can be connected by providing a vent hole on the annular tension belt 5), and when the support airbag 11 is inflated and bulged, an annular recess 6 is formed on its surface by pulling by the annular tension belt 5, and a plurality of the massage airbags 12 fall into the annular recess 6. The existence of the annular recess 6 allows more massage airbags 12 to be arranged on the support airbag 11. In addition, the annular tension belt 5 can also ensure the connection strength between it and the support airbag 11.

[0042] In a preferred embodiment, the plurality of massage air bags 12 are enclosed and arranged at a position closer to the central axis of the support air bag 11, and the corresponding annular tension belt 5 is also arranged at a position closer to the central axis of the support air bag 11. Through this arrangement, the plurality of massage air bags 12 are more inclined toward the direction closer to the central axis of the support air bag 11 while being stably supported by the annular recess 6, so that the plurality of massage air bags 12 can be more gathered and concentrated, thereby providing a better massage effect. It should also be noted that the size of the massage air bag 12 needs to be accurately selected according to actual needs to avoid interference between the air bags.

[0043] In a preferred embodiment, the support airbag 11 is first inflated to raise the initial height of the massage airbag 12. The massage airbag 12 can be inflated or deflated by the controller 33 according to a specific timing. For example, each massage airbag 12 operates independently, and multiple massage airbags 12 are inflated or deflated at the same time, forming a dot matrix massage as a whole. It can also be that among the multiple massage airbags 12, at least one massage airbag 12 is in a saturated state, and at least one of the adjacent massage airbags 12 is in an unsaturated state (not including a deflated state), and the positions of the multiple massage airbags 12 that are inflated and bulged according to a specific timing can slide continuously, thereby forming a continuous massage with a trailing effect.

[0044] In a preferred embodiment, the multiple massage air bags 12 are arranged in a closed manner to present an arrangement shape including but not limited to a Y-shape, a circle, a plum blossom shape or a snowflake shape, which can be selected according to the actual scenario.

[0045] In a preferred embodiment, the massage airbag 12 may be configured in a shape including but not limited to a fan-shaped, circular, elliptical, oblong, spindle-shaped or shuttle-shaped shape, which may be selected according to the actual scenario.

[0046] In a preferred embodiment, the massage airbag 12 can be any one of a single-layer airbag, a double-layer airbag or a multi-layer airbag, and can be selected and used according to the actual scenario.
