Description

Technical Field

[0002] A pneumatic seat massage system is often installed on vehicle seats. The pneumatic seat massage system generally includes an air pump, a valve body group, a control unit, and several air bags between the face cover and the foam. The control unit controls the working status of different valve bodies in the valve body group to control the inflation and deflation status and inflation and deflation sequence of each air bag. Each air bag is lifted up and dropped down in a different order and frequency, acting on the body surface of the passenger to produce a comfortable massage effect.

[0003] In order to enhance the massage intensity, multi-stage air bags are usually used to increase the lifting height. However, due to the increase in the relative volume of the multi-stage air bags, the time it takes for the air bags to be inflated to reach the maximum height increases, and the interval from lifting to falling back to the next lifting increases, which reduces the overall massage effect.

DETAILED DESCRIPTION

[0054] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0055] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0056] Example 1

[0057] As the technical problem mentioned in the background technology, the present application proposes a novel pneumatic massage system, including at least one airbag group structure, which is arranged between the seat foam 200 and the face cover, the airbag group structure 100 includes at least one extended-range airbag body 110 and at least one quick-acting airbag body 120, the extended-range airbag body 110 is connected to the first air pipeline 310, the quick-acting airbag body 120 is connected to the second air pipeline 320, the extended-range airbag body 110 and the quick-acting airbag body 120 are arranged adjacent to each other, and the quick-acting airbag body 120 can accommodate a gas volume that is less than half of the gas volume that the extended-range airbag body 110 can accommodate;

[0058] It also includes a gas source 400, at least one valve body group 500 and a control unit 600;

[0059] The valve body group 500 includes at least one first valve body 510 and at least one second valve body 520 that are independently controlled. The first valve body 510 is connected to the first air pipeline 310, and the second valve body 520 is connected to the second air pipeline 320. The control unit 600 can control the actuation of the air source 400, the first valve body 510, and the second valve body 520. When the extended-range airbag body 110 maintains pressure, the quick-acting airbag body 120 performs at least one inflation and deflation action.

[0060] Specifically, the first valve body 510 is connected to the range-extending airbag body 110 through the first air pipeline 310, the second valve body 520 is connected to the quick-acting airbag body 120 through the second air pipeline 320, and the air source 400 and the valve body group 500 are connected by air pipes; the control unit 600 can control the air source 400 to output high-pressure gas, and independently control the first valve body 510 and the second valve body 520. When the control unit 600 controls the air source 400 to work, output high-pressure gas, and control the first valve body 510 to open the charging passage, the high-pressure gas is input to the range-extending airbag body 110 through the first valve body 510 and the first air pipeline 310, and the range-extending airbag body 110 expands and rises. When the range-extending airbag body 110 is quickly filled, the control unit 600 can control the first valve body to close the charging passage, so that the amount of gas in the range-extending airbag body 110 is in a pressure-maintaining state. The control unit 600 can control the second valve body 520 to open the inflation passage during the pressure maintaining period of the extended-range airbag 110, and the high-pressure gas is input to the quick-acting airbag 120 through the second valve body 520 and the second air pipeline 320; since the quick-acting airbag 120 is configured to accommodate a gas volume that is smaller than half of the gas volume that the extended-range airbag 110 can accommodate, under the same high-pressure gas, the quick-acting airbag 120 is filled in a shorter time and the altitude is quickly increased; the control unit 600 can control the second valve body 520 to switch to the deflation passage, since the quick-acting airbag 120 is configured to accommodate a gas volume that is smaller than half of the gas volume that the extended-range airbag 110 can accommodate, the quick-acting airbag 120 is deflated in a shorter time and the altitude is quickly lowered. On the basis of the height of the extended-range airbag 110, the height of the quick-acting airbag 120 when inflated can increase the maximum lifting height of the entire massage airbag group structure; the quick-acting airbag 120 quickly inflates, quickly reaches the lifting height, and quickly deflates, quickly reaches the deflated state; the extended-range airbag 110 and the quick-acting airbag 120 cooperate to increase the maximum lifting height of the massage, and realize the speed and frequency of massage switching; thereby improving the comfort of the massage, such as Figure 1-2 shown.

[0061] Of course, in order to save the time for the airbag group structure 100 to reach the highest height, it is more reasonable that the control unit 600 controls the inflation action of the extended-range airbag 110 while the quick-acting airbag also enters the inflation action; or, after a period of time has passed since the extended-range airbag 110 starts to inflate, the quick-acting airbag also starts to inflate; after the extended-range support body 110 is full and starts to maintain pressure, the quick-acting airbag 120 starts to inflate. This setting is not necessary; the time when the quick-acting airbag starts to inflate can be set according to actual needs.

[0062] Specifically, the control unit 600 and the valve body assembly 500 may be separately and independently provided, or may be integrated in a housing, such as Figure 2 shown.

[0063] Specifically, the amount of gas that the extended-range airbag 110 can accommodate refers to the amount of gas when the extended-range airbag 110 is filled with gas of a certain pressure value Pa, and usually at this time the extended-range airbag 110 reaches the maximum lifting height; the amount of gas that the quick-acting airbag 120 can accommodate refers to the amount of gas when the extended-range airbag 120 is filled with gas of the same pressure value Pa or close to the pressure value Pa.

[0064] Furthermore, in order to achieve a higher lifting height of the quick-acting airbag 120 , the quick-acting airbag 120 is also configured to accommodate a gas volume that is one tenth of the gas volume that the range-extending airbag 110 can accommodate.

[0065] Specifically, the control unit 600 can control the extended-range airbag 110 to perform two or more inflation and deflation actions during the pressure maintenance period, which will cause the entire airbag group structure 100 to act on the passenger's back, buttocks or other areas for two or more massage actions, giving the human back a feeling similar to that of rapid tapping by human hands, so as to enhance the comfort of the massage.

[0066] Specifically, the control unit 600 may first control the first valve body 510 to fill the range-extending airbag 110 with air, and then control the second valve body 520 to switch between the inflation path and the deflation path to inflate and deflate the quick-acting airbag 120; or, the control unit 600 may control the first valve body 510 to start inflating the range-extending airbag 110, and before the range-extending airbag 110 is filled, control the second valve body 520 to start switching between the inflation path and the deflation path to inflate and deflate the quick-acting airbag 120. 0 inflation and deflation, the quick-acting airbag body 120 enters the inflation stage earlier, which is beneficial for the entire airbag group structure 100 to quickly reach a higher lifting height; alternatively, the control unit 600 can control the first valve body 510 to inflate the extended-range airbag body 110 while starting to control the second valve body 520 to switch between the inflation passage and the deflation passage to inflate and deflate the quick-acting airbag body 120, and the quick-acting airbag body 120 enters the inflation stage earlier, which is beneficial for the entire airbag group structure 100 to quickly reach a higher lifting height.

[0067] Specifically, the air source 400 is an air pump, or a vehicle body air source, or is composed of an air pump and an air storage device.

[0068] Specifically, the passage states of the first valve body 510 include an inflation passage, an exhaust passage, and a closed passage; when in the inflation passage, the gas source 400 is connected to the range-extending airbag 110, and the high-pressure gas of the gas source 400 enters the range-extending airbag 110 through the inflation passage of the first valve body 510. Figure 7a When the air leakage passage is in the state, the range-extending airbag 110 is connected to the outside air through the air leakage passage of the first valve body 510, and the gas in the range-extending airbag 110 is discharged to the outside air through the air leakage passage of the first valve body 110, as shown Figure 7cWhen the passage is closed, the extended-range airbag 110 is disconnected from the external air and the air source 400, and the extended-range airbag 110 is pressurized, as shown. Figure 7b As shown; the control unit 600 can control the first valve body 510 to switch between the inflation passage, the deflation passage, and the closing passage; the first valve body 110 can be implemented by a combination of a two-position two-way valve body and a two-position three-way valve body, or by a combination of a one-way valve and a two-position three-way valve body.

[0069] Specifically, the second valve body 120 has an inflation passage including an inflation passage and an air release passage; when the inflation passage is inflated, the gas source 400 is connected to the quick-acting airbag 120, and the high-pressure gas of the gas source 400 enters the quick-acting airbag 120 through the inflation passage of the second valve body 520, such as Figure 7a As shown; when the deflation passage is opened, the quick-acting airbag 120 is connected to the outside air through the deflation passage of the second valve body 520, and the gas in the quick-acting airbag 120 is discharged to the outside air through the deflation passage of the second valve body 520; the control unit 600 can control the second valve body 520 to switch between the inflation passage and the deflation passage; the second valve body 120 can adopt a two-position three-way valve body.

[0070] Specifically, the first valve body 510 and the second valve body 520 may be electromagnetic valve bodies or valve bodies driven by memory alloy wires.

[0071] Specifically, the range-extending airbag 110 and the quick-acting airbag 120 are formed of a film material to form an airbag structure. The range-extending airbag 110 is connected to the first valve body 510 through the first air pipeline 310 , and the quick-acting airbag 120 is connected to the second valve body 520 through the second air pipeline 320 .

[0072] Specifically, the first air pipeline 110 and the second air pipeline 120 can use common air pipes on the market, such as PU air pipes.

[0073] Furthermore, the extended-range airbag body 110 and the quick-acting airbag body 120 are fixedly connected together, for example, by hot-melt connection (high-frequency welding or ultrasonic welding) or adhesive connection, etc. Figure 3a-3f As shown, the constraint of the positions of the two is conducive to the effective superposition of height during inflation, and is conducive to the lifting height of the airbag group structure 100 accurately acting on the back or buttocks or other areas of the human body in a specified direction, which is conducive to improving the massage effect.

[0074] Furthermore, the airbag assembly structure 100 is provided with one or more quick-acting airbag bodies 120, such as Figure 3a-3c shown.

[0075] Specifically, each quick-acting airbag body 120 is connected to a different second valve body 520, and the control unit 600 can independently control each second valve body, thereby realizing a variety of different massage height combinations and providing more types of massage modes.

[0076] Specifically, the airbag group structure 100 is provided with one or more range-extending airbags for increasing the height of massage.

[0077] Furthermore, the extended-range airbag 110 is a first-level or higher airbag; the quick-acting airbag 120 is a first-level or higher airbag, such as Figure 3a-3f shown.

[0078] Specifically, the primary airbag body refers to an airbag structure consisting of only one upper membrane and one lower membrane, such as Figure 3b As shown, the extended-range airbag 110 and the quick-acting airbag 120 are both primary airbag structures; the secondary airbag refers to an airbag structure formed by two adjacent side membranes of the primary airbag being sealed and connected together and having an air path connected, such as Figure 3a As shown in , the extended-range airbag 110 is a second-stage airbag, and the quick-acting airbag is a first-stage airbag; the same applies to airbags of more stages, which will not be described in detail.

[0079] Further, the inflation and deflation actions include an inflation action 810 and a deflation action 820. The control unit 600 can control the inflation action 810 of the quick-acting airbag 120 to perform at least one sub-inflation and deflation action 830. The control unit 600 can control the actuation of the second valve body 520 so that the quick-acting airbag 120 performs at least one sub-inflation and deflation action 830 after the inflation action 810. The sub-inflation and deflation actions 830 include a sub-deflation action 832 and a sub-inflation action 831. The amount of gas filled in when the quick-acting airbag 120 performs the sub-inflation action 831 is the sub-inflation amount, and the amount of gas discharged when the quick-acting airbag 120 performs the sub-deflation action 832 is the sub-deflation amount. The sub-inflation amount and the sub-deflation amount are less than the total gas volume of the quick-acting airbag 120 when it is in the fullest state, as shown in FIG. Figure 4a-4d and Figure 5a-5d shown.

[0080] Specifically, the control unit 600 can control the second valve body 520 to be in the inflation path, the gas source 400 is connected to the quick-acting airbag 120, and the high-pressure gas enters the quick-acting airbag until the quick-acting airbag 120 is full. At this time, the amount of gas in the quick-acting airbag 120 is the total amount of gas, and the lifting height of the quick-acting airbag 120 reaches the maximum value, such as Figure 4b and 5bAs shown; the control unit 600 can control the second valve body 520 to switch to the deflation passage, and the quick-acting airbag 120 is connected to the external air to perform this as a sub-deflation action 832, and part of the gas volume in the quick-acting airbag 120 (measured according to the air pressure value P1) is discharged to the external air, which promotes the height of the quick-acting airbag 120 to drop partially, such as Figure 4c and 5c As shown; the control unit 600 can control the second valve body 520 to switch to the inflation channel to perform the sub-inflation action 831, the quick-acting airbag 120 is connected to the gas source 400, and the high-pressure gas quickly enters the quick-acting airbag 120, and the quick-acting airbag height quickly returns to the height before the sub-deflation action 830, such as Figure 4d and 5d Since the air volume of the sub-inflation action 831 and the sub-deflation action 832 is less than the total air volume at the highest height of the quick-acting airbag 120, the height descent and height recovery of the quick-acting airbag 120 can be achieved at a faster speed. At the extended-range height of the extended-range airbag 110, the sub-inflation and deflation actions of the quick-acting airbag 120 increase the speed and frequency of the massage action, giving the back, buttocks or other areas of the human body a feeling similar to that of rapid tapping by human hands, so as to enhance the comfort of the massage.

[0081] Specifically, when the quick-acting airbag 120 is set to the inflation action 810 and reaches the full state, the control unit 600 can control the second valve body 520 so that the quick-acting airbag 120 first performs the sub-deflation action 832 and then performs the sub-inflation action 831; or, when the quick-acting airbag 120 is set to the inflation action 810 and does not reach the full state, the control unit 600 can control the second valve body 520 so that the actuator cavity 120 first performs the sub-inflation action 831 and then performs the sub-deflation action 832.

[0082] Furthermore, the height of the quick-acting airbag 120 after the sub-deflation action 832 is between 30% and 90% of the height after the sub-inflation action 831. The massage effect of such height difference and the speed of height difference change is relatively comfortable for the human body.

[0083] Furthermore, the control unit 600 may control the duration of the sub-inflation action 831 and the sub-deflation action 832 of the fast-acting airbag 120 to be between 150 ms and 650 ms.

[0084] Furthermore, the control unit 600 may control the duration of the sub-inflation action 831 in a sub-inflation and deflation action 830 of the quick-acting airbag 120 to be the same as the duration of the sub-deflation action 832 .

[0085] Specifically, the control unit 600 can control the quick-acting airbag 120 to perform a sub-deflation action 832. After the control unit 600 controls the second valve body 520 to be in the deflation channel for any time value within the range of 150ms-650ms, part of the gas in the quick-acting airbag 120 is discharged into the external air, and the height of the quick-acting airbag is reduced. Then, a sub-inflation action 831 is performed, and the control unit 600 controls the second valve body 520 to switch to the inflation channel and maintain the same time length. The high-pressure gas of the air source 400 is filled into the quick-acting airbag 120, and the quick-acting airbag returns to the height before the sub-deflation action 832. The quick-acting airbag's rapid sub-inflation and deflation action 830 and rapid height change act on the back, buttocks or other areas of the human body, thereby increasing the speed of massage and improving the comfort of massage. When the extended-range airbag body 110 maintains the extended-range lifting height, the quick-acting airbag body continuously performs two or more sub-inflation and deflation actions. The overall lifting height of the airbag group structure 100 becomes higher, and the height difference changes rapidly. The airbag group structure 100 replaces human hands to quickly tap the back, buttocks or other areas of the human body, and the massage effect is more comfortable.

[0086] Specifically, as described above, when the quick-acting airbag 120 is set to the inflation action 810, that is, it reaches the full state, the control unit 600 can control the second valve body 520 so that the quick-acting airbag 120 first performs a sub-deflation action 832 for a certain duration, and then performs a sub-inflation action 831 for a certain duration; or, when the quick-acting airbag 120 is set to the inflation action 810 and does not reach the full state, the control unit 600 can control the second valve body 520 so that the quick-acting airbag 120 first performs a sub-inflation action 831 for a certain duration, and then performs a sub-deflation action 832 for a certain duration.

[0087] Further, the control unit 600 can control the quick-acting airbag 120 to perform at least two sub-inflation and deflation actions 830 after the inflation action 810, and then perform the deflation action 820 to the deflated state, and the sub-inflation amounts of all the sub-inflation actions 831 are the same, or the durations of all the sub-inflation actions 831 are the same, such as Figure 6a shown.

[0088] Specifically, the quick-acting airbag 120 performs two consecutive sub-inflation and deflation actions 830 within the sub-inflation and deflation time period 840 (referring to the period of performing one or more sub-inflation and deflation actions). In the first sub-inflation and deflation action 830, the volume of the sub-deflation amount or the sub-inflation amount is V1; in the second sub-inflation and deflation action 830, the volume of the sub-deflation amount or the sub-inflation amount is also V1. Alternatively, in the first sub-inflation and deflation action 830, the time of the sub-inflation action 831 or the sub-deflation action 832 is T1; in the second sub-inflation and deflation action 830, the time of the sub-deflation action 832 or the sub-inflation action 831 is also T1. Therefore, during the two sub-inflation actions 830, the height difference of the quick-acting airbag body changes in the same or approximately the same way, and the force of lifting the human body is the same or approximately the same; the speed of the height change of the quick-acting airbag body 120 is different, and the speed of lifting and massaging the human body is the same; the force and speed of the airbag group structure 100 hitting the back, buttocks or other areas of the human body are almost the same, and the back, buttocks or other areas of the human body feel a relatively consistent massage and knocking feeling. Of course, here we only use two sub-inflation and deflation actions 830 as an example for explanation, and do not limit the number of sub-inflation and deflation actions 830 of the quick-acting airbag body 120 within the sub-inflation and deflation time period 840, and there can also be three or more sub-inflation and deflation actions 830.

[0089] Furthermore, the control unit 600 can control the quick-acting airbag 120 to perform at least two sub-inflation actions after the inflation action and before the deflation action, and the sub-inflation amounts of at least two sub-inflation actions are different, or the sub-inflation durations of at least two sub-inflation actions are different.

[0090] Specifically, the fast-acting airbag 120 performs two consecutive sub-inflation and deflation actions 830 within the sub-inflation and deflation time period 840 (referring to the period during which one or more sub-inflation and deflation actions are performed). In the first sub-inflation and deflation action 830, the volume of the sub-deflation amount or the sub-inflation amount is V1; in the second sub-inflation and deflation action 830, the volume of the sub-deflation amount or the sub-inflation amount is V2, and the two volumes V1 and V2 are different at the same air pressure value. Alternatively, in the first sub-inflation and deflation action 830, the duration of the sub-inflation action 831 or the sub-deflation action 832 is T1; in the second sub-inflation and deflation action 830, the duration of the sub-deflation action 832 or the sub-inflation action 831 is also T2, and T1 and T2 are different, such as Figure 6b and 6cAs shown. Therefore, during the two sub-inflation actions 830, the height difference of the quick-acting airbag body 120 changes differently, and the force of lifting the human body is different; the speed of the height change of the quick-acting airbag body 120 is also different, and the speed of lifting and massaging the human body is different; the force and speed of the airbag group structure 100 striking the back, buttocks or other areas of the human body are different, and the back, buttocks or other areas of the human body feel more diverse massage strikes. Of course, here only two sub-inflation action examples are used for explanation, and the number of sub-inflation and deflation actions 830 is not limited. There can also be three or more sub-inflation and deflation actions 830, and the sub-inflation amounts between two sub-inflation and deflation actions 830 are different, or there can be three or more sub-inflation amounts that are different, all of which fall within the protection scope of this application.

[0091] Specifically, as described above, the inflation action 810 and the sub-inflation action 831 of the quick-acting airbag 120 are accompanied by the switching of the second valve body 520 to the inflation path, and the deflation action 820 and the sub-deflation action 832 are accompanied by the switching of the second valve body 520 to the deflation path, and the action of the second valve body 120 is accompanied by the coordination, so Figure 6a-6c The curve of the second valve body 120 switching represents the state of the quick-acting airbag 120. The higher position line in the curve indicates that the second valve body 520 switches to the inflation path; the lower position line indicates that the second valve body 520 switches to the deflation path. The same principles of the extended-range airbag 110 and the first valve body 510 are not repeated here. After the inflation action 810, the extended-range airbag 110 maintains a pressure-maintaining state 850 during the inflation and deflation time period 840 of the quick-acting airbag 120. The first valve body 510 is in a state as shown in FIG. Figure 7b Status shown.

[0092] In a specific embodiment, for example, the fast-acting airbag 120 performs two consecutive sub-inflation and deflation actions during the inflation and deflation action. In the first sub-inflation and deflation action, the duration of the sub-deflation action and the sub-inflation action is T1, for example, 200ms; in the second sub-inflation and deflation action, the duration of the sub-deflation action or the sub-inflation action is T2, for example, 400ms.

[0093] Furthermore, the same quick-acting airbag 120 can be connected to the air source 400 via one or more second valve bodies 520. When multiple second valve bodies 520 are arranged in parallel and are in the inflation path or deflation path at the same time, it is beneficial to expand the total cross-sectional area of ​​the inflation path or deflation path, and improve the inflation speed or deflation speed of the quick-acting airbag 120. Figure 7d shown.

[0094] Furthermore, a plurality of quick-acting airbags 120 are arranged on the range-extending airbag 110. The control unit 600 can control the range-extending airbag 110 to perform the inflating and deflation actions and the sub-inflating and deflation actions 830 in a certain order during the pressure-maintaining and range-extending period, thereby improving the massage effect. Figure 8 shown.

[0095] Furthermore, the control unit 600 can control the quick-acting airbag 120 to perform an inflating and deflation action when the range-extending airbag 110 is in a deflated and collapsed state, such as Fig. 9 As shown, to provide a massage mode with a lower height.

[0096] Furthermore, the control unit 600 may control the range-extending airbag 110 to be in a partially inflated state, and the quick-acting airbag 120 to perform an inflating and deflating action, so as to provide a massage mode with a transitional height.

[0097] Furthermore, the control unit 600 can control different inflation and deflation states of the airbag group structure 100 to achieve multi-modal massage height, massage intensity, and massage speed.

[0098] Furthermore, at least one flexible protrusion 130 is provided on one side of the airbag assembly structure 100 close to the face cover, and an elastic filler 131 is provided in the flexible protrusion 130. Figure 3f , 5a As shown in Figure 5-5d, when the airbag group structure 100 is lifted up, its lifting force is transmitted to the back of the human body through the flexible protrusion 130. During massage, the effective area and force are more concentrated, and a certain area of ​​the human body can feel a stronger massage squeezing feeling. The elastic filler 131 is conducive to maintaining the shape of the flexible protrusion 130, such as a sponge or a multi-porous rubber silicone material. When the airbag group structure 100 changes from a flattened state to an inflated state, the flexible protrusion 130 is quickly changed to an effective protrusion shape by the elastic restoring force of the elastic filler 131.

[0099] Furthermore, the quick-acting airbag 120 is close to the face cover, the extended-range airbag 110 is placed away from the foaming 200 side, the flexible protrusion 130 is arranged on the side of the quick-acting airbag 120 close to the face cover, and the flexible protrusion 130 is connected with the air path of the quick-acting airbag 120, the quick-acting airbag 120 is close to the back or buttocks or other areas of the human body, and when the quick-acting airbag 120 is inflated and deflated and the sub-inflated and deflated action, the massage feeling or massage knocking feeling transmitted to the back or buttocks or other areas of the human body through the face cover or the face cover and the seat heater is relatively obvious; or, the quick-acting airbag 120 is far away from the face cover On the side, the extended-range airbag 110 is placed close to the foaming side, the flexible protrusion 130 is arranged on the side of the extended-range airbag 110 close to the face cover, and the flexible protrusion 130 is connected with the air path of the extended-range airbag 110. In this way, the extended-range airbag 110 is close to the back of the human body, and the inflation and deflation actions and sub-inflation and deflation actions of the fast-acting airbag 120 are transmitted to the back or buttocks or other areas of the human body through the extended-range airbag 120, the face cover or the face cover and the seat heater. The transmission path is increased, the medium increases, and the force transmission loss is relatively large. The massage effect can also be achieved, but the massage effect is good in the aforementioned placement position.

[0100] Specifically, the flexible protrusion 130 is made of the same film material as the airbag group structure 100, and is fixedly connected to the airbag group structure. It is inflated and deflated as the extended-range airbag body 110 or the quick-acting airbag body 120 is inflated and deflated. When it is filled with high-pressure gas, it acts on the back, buttocks or other areas of the human body to transmit a stronger massage force.

If the inflation and deflation actions of two or more airbag group structures 100 are completely consistent, a valve body group 500 can be shared.

[0104] Furthermore, the plurality of airbag group structures 100 are arranged along the positions of the human meridians 701, such as Fig. 9 As shown, it is arranged along the bladder meridian 701 of the human body to achieve a more comfortable massage and relaxation effect on human muscles.
