DETAILED DESCRIPTION

[0063] The present application is further described in detail below in conjunction with FIG. 1-FIG. 14, and in conjunction with FIG. 15-FIG. 23.

[0064] As mentioned in the background, in view of the problems in the prior art, the present application proposes a ring-shaped kneading massage system. The ring-shaped kneading massage system comprises:

[0065] The air bag assembly 1 and the control assembly 2, specifically:

[0066] The air bag assembly 1 comprises massage air bags 11 and a supporting air bag 12, the massage air bags 11 are arranged in a closed loop structure, and the supporting air bag 12 is arranged on the side of the central axis of the supporting air bag 12.

[0067] The control assembly 2 comprises an air source 21, an air distribution valve 22, and a controller 23,

[0068] The air source 21 inflates the supporting air bag 12 and the massage air bags 11 through the air distribution valve 22;

[0069] The air distribution valve 22 is configured to adjust the flow state of the gas;

[0070] The controller 23 controls the air source 21 and the air distribution valve 22 to inflate or deflate the support air bag 12 and the massage air bag 11 in sequence according to a specific timing. According to the specific timing, at least one of the massage air bags 11 is in a full inflation state, and at least one of the massage air bags 11 adjacent to the massage air bag 11 in the full inflation state is in a non-full inflation state (excluding the deflation state). The positions of the massage air bags 11 inflated according to the specific timing can sequentially shift. The non-full inflation state includes all states other than the full inflation state and the deflation state, such as a 30% inflation state, a 50% inflation state, or a 70% inflation state.

[0071] When the occupant needs to be massaged due to driving fatigue, the massage system is started, and the controller 23 controls the air pump and the air distribution valve 22 to inflate or deflate the support air bag 12 and the massage air bag 11 in sequence according to a specific timing to achieve pneumatic pressing on the occupant side. According to the specific timing preset by the controller 23, at least two adjacent massage air bags 11 are inflated at each specific time period, and the positions of the massage air bags 11 inflated according to the specific timing can sequentially shift. As the specific timing is repeatedly executed, the occupant side can feel a ring-shaped kneading massage, thereby improving the massage effect and providing a better massage experience for the occupant. In addition, the support air bag 12 can also lift the initial height of the massage air bag 11, support the massage air bag 11, and improve the massage intensity of the massage air bag 11, thereby further improving the massage effect.

[0072] Optionally, the air source 21 can be any one of a vehicle body air source 21, an air tank, or an air pump. Taking the air pump as an example, the air pump inflates the massage air bag 11 and the support air bag 12 through the air distribution valve 22.

[0073] Optionally, the air distribution valve 22 includes an air inlet 221, an inflation port 222, a deflation port 223, and a valve core 224. The air inlet 221 is in communication with the air pump, the inflation port 222 is in communication with the support air bag 12 and the massage air bag 11, and the controller 23 is configured to control the movement of the valve core 224 to control the opening of the air inlet 221 and the closing of the deflation port 223, or the closing of the air inlet 221 and the opening of the deflation port 223. It should be noted that the air distribution valve 22 is a conventional configuration in the art, and therefore the specific structure of the air distribution valve 22 is not shown in the drawings.

[0074] Optionally, based on a specific timing, the inflation and deflation state of the support air bag 12 can be full inflation saturation state, non-full inflation non-saturation state and deflation state. After the massage starts, the controller 23 will first control the air source 21 to inflate the support air bag 12 through the air distribution valve 22 until the support air bag 12 reaches a stable state. When the support air bag 12 is in a full inflation saturation state or a non-full inflation non-saturation state, the support air bag 12 will lift the initial height of the massage air bag 11, and at the same time, it can also increase the massage intensity of the massage air bag 11. In actual application scenarios, the inflation and deflation state of the support air bag 12 can be set as needed.

[0075] Optionally, the support air bag 12 can be a single-capsule air bag 3 formed by integral molding, or a spliced multi-capsule air bag 4 formed by splicing a plurality of sub-air bags in the circumferential direction. In actual application scenarios, the arrangement mode of the support air bag 12 can be selected as needed, and in addition, in order to ensure good massage effect, the area of the support air bag 12 should not be less than the area of the closed loop structure formed by the plurality of massage air bags 11.

[0076] Optionally, the support air bag 12 can be any one of a single-layer air bag, a double-layer air bag or a multi-layer air bag, which can be selected for use according to actual scenarios.

[0077] Optionally, the support air bag 12 can be arranged as a ring-shaped air bag, a circular air bag, a square air bag or other polygonal air bags, but all should meet the requirement that the plurality of massage air bags 11 can be arranged and enclosed on the support air bag 12.

[0078] Optionally, the support air bag 12 is configured as a ring-shaped air bag with a tire-like shape, and the plurality of massage air bags 11 are arranged and enclosed closer to the central axis of the support air bag 12. Due to the effect of the shape of the support air bag 12, when the support air bag 12 is inflated and bulges, the plurality of massage air bags 11 will simultaneously gather towards the direction closer to the central axis of the support air bag 12. From the appearance, the included angle between the central axis of the massage air bag 11 and the central axis of the support air bag 12 is an acute angle. Such arrangement enables the massage air bag 11 to give the occupant a stronger squeezing feeling during massage, further improving the massage effect.

[0079] Optionally, the massage air bag 11 can be configured in a shape including but not limited to a fan shape, a circular shape, an elliptical shape, an oblong shape, a spindle shape or a shuttle shape, which can be selected for use according to actual scenarios.

[0080] Optionally, the massage air bag 11 can be any one of a single-layer air bag, a double-layer air bag or a multi-layer air bag, which can be selected for use according to actual scenarios.

[0081] Optionally, when the massage air bag 11 is configured as a double-layer air bag or a multi-layer air bag, the top pneumatic layer of the massage air bag 11 can be designed as a layer with smaller volume compared with other pneumatic layers, so that when the massage air bag 11 is inflated, the inflation speed of the massage air bag 11 can be accelerated, the inflation speed of the top starting layer is accelerated, and the massage air bag 11 can respond to the massage stimulus more quickly.

[0082] Optionally, the arrangement forms of the plurality of massage air bags 11 arranged in a surrounding manner include but are not limited to Y-shaped, circular, plum blossom-shaped or snowflake-shaped, and can be selected according to actual scenes.

[0083] Optionally, for the convenience of description, the plurality of massage air bags are numbered in sequence, and the dynamic process of the circular kneading massage is as follows:

[0084] At t0, the massage air bag 1 is continuously inflated, the massage air bag 1 reaches a full inflation saturation state at t1 (the massage air bag 1 has started to be inflated at t3 described below, and the inflation is connected to t0 at t4), the massage air bag 2 starts to be inflated and reaches a non-full inflation non-saturation state at t1, the massage air bag 3 continuously deflates and reaches a deflation state at t1 (the massage air bag 3 has started to deflate at t3 described below, and the deflation is connected to t0 at t4), and the massage air bag 4 starts to deflate and reaches a non-full inflation non-saturation state at t1.

[0085] At t1, the massage air bag 1 starts to deflate and reaches a non-full inflation non-saturation state at t2, the massage air bag 2 continuously inflates and reaches a full inflation saturation state at t2, the massage air bag 3 starts to inflate and reaches a non-full inflation non-saturation state at t2, and the massage air bag 4 continuously deflates and reaches a deflation state at t2.

[0086] At t2, the massage air bag 1 continuously deflates and reaches a deflation state at t3, the massage air bag 2 starts to deflate and reaches a non-full inflation non-saturation state at t3, the massage air bag 3 continuously inflates and reaches a full inflation saturation state at t3, and the massage air bag 4 starts to inflate and reaches a non-full inflation non-saturation state at t3.

[0087] At t3, the massage air bag 1 starts to inflate again and reaches a non-full inflation non-saturation state at t4, the massage air bag 2 continuously deflates and reaches a deflation state at t4, the massage air bag 3 starts to deflate and reaches a non-full inflation non-saturation state at t4, and the massage air bag 4 continuously inflates and reaches a full inflation saturation state at t4.

[0088] From t4 to t0, the timing is restarted, and thus, in each specific time period, at least two adjacent massage air bags are inflated and inflated, the position of the inflated and inflated massage air bags is controlled to be shifted in succession, and with the cyclic execution of the specific timing, the passenger side will feel the circular kneading massage.

[0089] Optionally, a collapsed annular kneading massage mode is also provided. For the convenience of description, the plurality of massage air bags are numbered in sequence. The dynamic process of the collapsed annular kneading massage mode is as follows:

[0090] In the t0-t1 time period, the massage air bag 1 and the massage air bag 2 are inflated to reach the full inflation saturation state, the massage air bag 3 is inflated to reach the non-full inflation non-saturation state in the t0-t1 time period, and the massage air bag 4 is in the deflation state; in the t1-t2 time period, the massage air bag 1 is in the deflation state, the massage air bag 2 and the massage air bag 3 are inflated to reach the full inflation saturation state, and the massage air bag 4 is inflated to reach the non-full inflation non-saturation state; in the t2-t3 time period, the massage air bag 2 is in the deflation state, the massage air bag 3 and the massage air bag 4 are inflated to reach the full inflation saturation state, and the massage air bag 1 is in the non-full inflation non-saturation state; in the t3-t4 time period, the massage air bag 3 is in the deflation state, the massage air bag 4 and the massage air bag 1 are inflated to reach the full inflation saturation state, and the massage air bag 2 is in the non-full inflation non-saturation state; with the time sequence cycle, the collapsed regions of the massage air bags sequentially slide in a direction, thereby forming the collapsed annular kneading massage mode.

[0091] Optionally, through specific time sequence configuration, the plurality of massage air bags can also be divided into a first air bag unit and a second air bag unit. In the first air bag unit, at least one of the massage air bags is in the full inflation saturation state, at least one of the massage air bags adjacent to the full inflation saturation state is in the non-full inflation non-saturation state, and at least one of the massage air bags adjacent to the non-full inflation non-saturation state is in the deflation state. The second air bag unit is consistent with the inflation and deflation state of the first air bag unit. The massage air bag in the deflation state in the first air bag unit is adjacent to the massage air bag in the full inflation saturation state in the second air bag unit. The massage air bag in the full inflation saturation state in the first air bag unit is adjacent to the massage air bag in the deflation state in the second air bag unit. The positions of the plurality of massage air bags inflated and inflated by the specific time sequence can sequentially slide;

[0092] Based on the above configuration, through specific time sequence cycle control, a central symmetric annular kneading massage mode can be formed. For the convenience of description, the plurality of massage air bags are numbered in sequence. The dynamic process of the central symmetric annular kneading massage mode is as follows:

[0093] t0-t1 time period, massage air bag 1 and massage air bag 4 are inflated to full inflation full saturation state, massage air bag 2 and massage air bag 5 are inflated to non-full inflation non-saturation state, massage air bag 3 and massage air bag 6 are in deflated state; t1-t2 time period, massage air bag 2 and massage air bag 5 are inflated to full inflation saturation state, massage air bag 3 and massage air bag 6 are inflated to non-full inflation non-saturation state, massage air bag 1 and massage air bag 4 are in deflated state; t2-t3 time period, massage air bag 3 and massage air bag 6 are inflated to full inflation full saturation state, massage air bag 1 and massage air bag 4 are inflated to non-full inflation non-saturation state, massage air bag 2 and massage air bag 5 are in deflated state; t3 moment to t0 moment, the timing starts again, the position of the plurality of massage air bags inflated and inflated by the specific timing is sequentially shifted, thereby forming a central symmetric ring type kneading massage mode, bringing better massage experience to the passenger.

[0094] Optionally, the ring type soft pressure massage system further comprises a limiting assembly 8, which is arranged in the support air bag 12 and corresponds to the massage air bag 11, and has an elastic deformation function. When the support air bag 12 is inflated, the limiting assembly 8 axially pulls the support air bag 12, so that a local recess 121 is formed on the surface of the support air bag 12, and the massage air bag 11 is located at the local recess 121.

[0095] When the passenger needs massage due to driving fatigue, the massage system is started, and the controller 23 controls the air source 21 and the gas distribution valve 22 to act, so as to inflate or deflate the support air bag 12 and the massage air bag 11, and realize the starting pressing of the passenger side. During the process, when the support air bag 12 is inflated, the limiting assembly 8 axially pulls the support air bag 12, so that a local recess 121 is formed on the surface of the support air bag 12, and the massage air bag 11 is located at the local recess 121. The local recess 121 can stably support the massage air bag 11, avoid the phenomenon of shaking, scattering and deviation of the massage air bag 11 in the process of being lifted, and make the massage air bag 11 more stably concentrated for massage, so as to improve the massage effect and further bring better massage experience to the passenger.

[0096] Optionally, the limiting assembly 8 is a tension belt 81 made of flexible material, which is fixedly installed between the upper film and the lower film of the support air bag 12. The number of the tension belt 81 is consistent with and corresponds to the number of the massage air bag 11. When the support air bag 12 is inflated, the surface of the support air bag 12 will form a pit-shaped recess 7 through the tension of the tension belt 81. The massage air bag 11 is located in the pit-shaped recess 7, and the pit-shaped recess 7 can stably support the massage air bag 11, avoid the phenomenon of shaking, scattering and deviation of the massage air bag 11 in the process of being lifted.

In this way, the plurality of massage air bags 11 are further inclined towards the central axis of the support air bag 12 when stably supported by the crater-shaped recess 7, and the plurality of massage air bags 11 are more concentrated, thereby providing better massage effect. It should be noted that the size of the massage air bag 11 should be accurately selected according to actual needs to avoid interference between the air bags.

[0098] Optionally, the support air bag 12 is configured as an annular air bag, and the limiting assembly 8 is an annular tightening belt 5 made of flexible material, which is fixedly installed between the upper film and the lower film of the support air bag 12 and separates the support air bag 12 into two chambers. When the support air bag 12 is inflated, a ring-shaped recess 6 is formed on the surface of the support air bag 12. The two chambers are communicated by opening a vent hole on the annular tightening belt 5. The plurality of massage air bags 11 fall into the ring-shaped recess 6, and the existence of the ring-shaped recess 6 allows more massage air bags 11 to be arranged on the support air bag 12, and the annular tightening belt 5 can ensure the connection strength between the annular tightening belt 5 and the support air bag 12.

[0099] A plurality of the massage air bags 11 are arranged in a closed manner closer to the central axis of the support air bag 12, and a plurality of the annular tightening belts 5 are arranged in a closed manner closer to the central axis of the support air bag 12.

It should be noted that the size of the massage air bag 11 should be accurately selected according to actual needs to avoid interference between the air bags.

[0100] Optionally, the support air bag 12 is first inflated to lift the initial height of the massage air bag 11, and the massage air bag 11 can be inflated or deflated according to a specific time sequence by the controller 23. For example, each massage air bag 11 acts independently, a plurality of massage air bags 11 are inflated or deflated at the same time, and a dot matrix massage is formed as a whole. Alternatively, at least one of the plurality of massage air bags 11 is in a saturated state, and at least one of the massage air bags 11 adjacent to the at least one massage air bag 11 is in a non-saturated state (not including a deflated state).

[0102] In actual application scenarios, the backrest and the seat of the car seat can be provided with the air bag assembly 1 described above, and the number of air bag assemblies 1 can be set to multiple groups. The multiple groups of air bag assemblies 1 can be arranged on the seat close to the human body's meridians to bring better massage experience to the passenger. The control assembly 2 can be flexibly arranged away from the head of the passenger according to the space of the seat. By setting the kneading massage system described above in the car seat, the driver fatigue can be relieved.

[0103] The following will be further described in detail in combination with FIG. 15-FIG. 23 and in combination with FIG. 1-FIG. 14.

[0104] As mentioned in the background, in view of the problems in the prior art, the application provides a pneumatic massage system for enhancing massage stability. The pneumatic massage system comprises:

[0105] The air bag assembly 1, the limiting assembly 8 and the control assembly 2.

[0106] The air bag assembly 1 comprises a supporting air bag 12 and a plurality of massage air bags 11 arranged around the supporting air bag 12; the limiting assembly 8 is arranged in the supporting air bag 122 and corresponds to the massage air bags 11. The limiting assembly 8 has an elastic deformation function. When the supporting air bag 12 is inflated, the limiting assembly 8 will axially pull the supporting air bag 12, so that the surface of the supporting air bag 12 forms a local concave part 121, and the massage air bags 11 are located at the local concave part 121.

[0107] The control assembly 2 comprises a gas source 21, a gas distribution valve group 32 and a controller 23. The gas source 21 inflates the air bag assembly 1 through the gas distribution valve group 32. The gas source 21 is configured to adjust the gas flow state. The controller 23 controls the gas source 21 and the gas distribution valve group 32 to act, so as to inflate or deflate the air bag assembly 1.

[0108] When the occupant needs to be massaged due to driving fatigue, the massage system is started, and the controller 23 controls the air source 21 and the air distribution valve 22 to act to inflate or deflate the supporting air bag 12 and the massage air bag 11, so as to achieve the starting pressing of the occupant side. During the process, when the supporting air bag 11 is inflated and bulges, the limiting assembly 8 will axially pull the supporting air bag 12, so that a local recessed part 121 is formed on the surface of the supporting air bag 12, and the massage air bag 11 is located at the local recessed part 121. The local recessed part 121 can stably support the massage air bag 11, avoid the phenomenon that the massage air bag 11 shakes and deviates during being lifted, and make the massage air bag 11 more stably concentrated for massage, so as to improve the massage effect and further bring better massage experience to the occupant.

[0109] Optionally, the air source 21 can select any one of a vehicle body air source, an air tank or an air pump. Taking the air pump as an example, the air pump inflates the massage air bag 11 and the supporting air bag 12 through the air distribution valve group 32.

[0110] Optionally, the air distribution valve group 32 includes an air inlet 221, an inflation port 222, a deflation port 223 and a valve core 224. The air inlet 221 is in communication with the air pump, the inflation port 222 is in communication with the supporting air bag 12 and the massage air bag 11, and the controller 23 is configured to control the movement of the valve core 224 to control the air inlet 221 to be opened and the deflation port 223 to be closed, or the air inlet 221 to be closed and the deflation port 223 to be opened. It should be noted that the air distribution valve group 32 is a conventional setting in the field, and therefore the specific structure of the air distribution valve group 32 is not shown in the drawing.

[0111] Optionally, the limiting assembly 8 is a tension belt 81 made of flexible material, which is fixedly installed between the upper film and the lower film of the supporting air bag 12, specifically by welding. The number of the tension belt 81 is consistent with and corresponds to the number of the massage air bag 11. When the supporting air bag 12 is inflated and bulges, the surface of the supporting air bag 12 will form a pit-shaped recessed part 7, and the massage air bag 11 is located in the pit-shaped recessed part 7. The pit-shaped recessed part 7 can stably support the massage air bag 11, avoid the phenomenon that the massage air bag 11 shakes and deviates during being lifted.

[0112] It should be noted that the tensioning belt 81 itself has elastic deformation function, more specifically, the tensioning belt 81 is flexible, that is, the tensioning belt 81 will be stretched axially with the bulging of the supporting air bag 12. Specifically, the tensioning belt 81 can be axially stretched or axially deformed, which occurs when the supporting air bag 12 is close to saturation or has been completely saturated. When the tensioning belt 81 is stretched, the reaction force of the tensioning belt 81 on the supporting air bag 12 is considered as the larger side of the force, and under this reaction force, the tensioning belt 81 will axially pull the supporting air bag 12. The selection of the tensioning belt 81 can be selected according to actual needs.

[0113] Optionally, the supporting air bag 12 is configured as an annular air bag, a plurality of the massage air bags 11 are arranged to be closer to the central axis of the supporting air bag 12, and a plurality of the tensioning belts 81 are arranged to be closer to the central axis of the supporting air bag 12, each of the tensioning belts 81 corresponds to one massage air bag 11. By this arrangement, the plurality of massage air bags 11 are more inclined to the central axis of the supporting air bag 12 when stably supported by the pit-shaped recess 7, and the plurality of massage air bags 11 are more concentrated, thereby providing better massage effect. It should be noted that the size of the massage air bag 11 needs to be accurately selected according to actual needs to avoid interference between the air bags.

[0114] Optionally, the supporting air bag 12 is configured as an annular air bag, the limiting assembly 8 is a ring-shaped tensioning belt 5 made of flexible material, and the ring-shaped tensioning belt 5 is coaxially arranged with the supporting air bag 12. The ring-shaped tensioning belt 5 is fixedly installed between the upper film and the lower film of the supporting air bag 12, specifically by welding. The ring-shaped tensioning belt 5 divides the supporting air bag 12 into two chambers (the two chambers are communicated by opening a vent hole on the ring-shaped tensioning belt 5), and the supporting air bag 12 is inflated and bulged when pulled by the ring-shaped tensioning belt 5. A plurality of the massage air bags 11 fall into the ring-shaped recess 6. The existence of the ring-shaped recess 6 allows more massage air bags 11 to be arranged on the supporting air bag 12, and the ring-shaped tensioning belt 5 can also ensure the connection strength between the ring-shaped tensioning belt 5 and the supporting air bag 12.

[0115] Optionally, the plurality of massage air bags 11 are arranged in a closed manner closer to the central axis of the supporting air bag 12, and the corresponding annular tension belt 5 is also arranged closer to the central axis of the supporting air bag 12. Through this arrangement, the plurality of massage air bags 11 are further inclined towards the central axis of the supporting air bag 11 when stably supported by the annular recess 6, and the plurality of massage air bags 11 can be more concentrated, thereby providing better massage effect. It should be noted that the size of the massage air bag 11 should be accurately selected according to actual needs to avoid interference between the air bags.

[0116] Optionally, the supporting air bag 12 is first inflated to lift the initial height of the massage air bag 11, and the massage air bag 11 can be inflated or deflated by the controller 23 according to a specific timing. For example, each massage air bag 11 acts independently, and a plurality of massage air bags 11 are inflated or deflated simultaneously to form a dot matrix massage. Alternatively, among the plurality of massage air bags 11, at least one massage air bag 11 is in a saturated state, and at least one adjacent massage air bag 11 is in a non-saturated state (excluding deflated state). The positions of the plurality of massage air bags 11 inflated according to the specific timing can be sequentially shifted, thereby forming a continuous massage with a trailing effect.

[0117] Optionally, the gas distribution valve group 32 includes a plurality of gas distribution valves 22, which are arranged one-to-one with the plurality of massage air bags 11, and the gas distribution valve 22 is configured to adjust the gas flow state. The controller 23 controls the gas source 21 and the gas distribution valve 22 to act according to a specific timing to sequentially inflate or deflate the supporting air bag 12 and the massage air bag 11. According to the specific timing, among the plurality of massage air bags 11, at least one massage air bag 11 is in a full-saturated state, and at least one adjacent massage air bag 11 is in a non-full-saturated state (excluding deflated state). The positions of the plurality of massage air bags 11 inflated according to the specific timing can be sequentially shifted.

[0118] When the occupant needs to be massaged due to driving fatigue, the massage system is started, and the controller 23 controls the air pump and the air distribution valve 22 to act in accordance with a specific timing sequence to inflate or deflate the support air bag 12 and the massage air bag 11 in sequence to achieve the pneumatic pressing of the occupant side. Based on the specific timing sequence preset by the controller 23, at least two adjacent massage air bags 11 are inflated in each specific time period, and the position of the inflated massage air bags 11 will sequentially shift under the control of the specific timing sequence. As the specific timing sequence is repeatedly executed, the occupant side will feel a circular kneading massage, thereby improving the massage effect and providing the occupant with a better massage experience. Moreover, the support air bag 12 can also lift the initial height of the massage air bag 11, support the massage air bag 11, and also increase the massage intensity of the massage air bag 11, thereby further improving the massage effect.

[0119] Optionally, based on the specific timing sequence, the inflation and deflation state of the support air bag 12 can be full inflation saturation state, non-full inflation non-saturation state, and deflation state. When the support air bag 12 is in the full inflation saturation state or the non-full inflation non-saturation state, the support air bag 12 will be inflated and lift the initial height of the massage air bag 11, support the massage air bag 11, and also increase the massage intensity of the massage air bag 11. In actual application scenarios, the inflation and deflation state of the support air bag 12 can be set as needed.
