DETAILED DESCRIPTION

[0033] The application will be further described in detail below in combination with Figs. 1-8.

[0034] As mentioned in the background, in view of the problems in the prior art, the embodiment of the application proposes a pneumatic pulse valve assembly, which is arranged between the air source body 1 and the gas using assembly 2 of the massage system, and specifically, the valve assembly 6 comprises:

[0035] The first valve body 3 and the second valve body 4 are arranged in combination and have different switching frequencies, and the switching frequency of the first valve body 3 is greater than that of the second valve body 4;

[0036] The first valve body 3 is provided at least one, and the first valve body 3 comprises a first air inlet end 31 and a first air outlet end 32, and the first air inlet end 31 is in communication with the air source body 1;

[0037] The second valve body 4 comprises a second air inlet end 44, an air charging end 42 and an air discharging end 45, the air charging end 42 is in communication with the gas using assembly 2, and the second air inlet end 44 is in communication with the first air outlet end 32.

[0038] The gas assembly 2 is configured to realize the pneumatic adjustment of the seat air bag 21.

[0039] When the gas source body 1 inflates the air bag 21, the first valve body 3 performs high-frequency and rapid switching operation to control the gas flow state into the second valve body 4, and the gas flow is controlled to pulse inflate the air bag 21 through the second valve body 4, so that the air bag 21 is sequentially lifted to bring the "puff puff puff" pressing feeling to the passenger's body, thereby bringing a better massage experience to the passenger.

[0040] Optionally, the first valve body 3 is configured as a gas source pulse generator with a rapid switching function, which can pulse the gas flow into the second valve body 4, and the selection of the gas source pulse generator can be a quick-acting valve, a staggered switching valve or a pneumatic hammer, but is not limited thereto. It should be noted that a general electromagnetic valve can also be selected as one of the gas source pulse generators.

[0041] Optionally, the gas source body 1 can be configured as a gas pump, and the first valve body 3 can be a pump valve integrated structure. The advantage of this arrangement is that the structure is compact and occupies less space. In addition, a gas storage tank 8 can be additionally arranged between the gas source body 1 and the first valve body 3 to store gas. Of course, the first valve body 3 can also be arranged as a separate structure with the pump valve of the gas pump, which is not limited herein.

[0042] Optionally, the first valve body 3 can be configured in multiple groups, and each group of the first valve body 3 has the same switching frequency. The multiple groups of the first valve body 3 can be configured to cyclically alternate the air supply to the second valve body 4, which can shorten the working time of each group of the first valve body 3 in unit time, thereby prolonging the service life of the first valve body 3.

[0043] Optionally, the first valve body 3 can be configured in multiple groups, and at least one group of the first valve body 3 has a switching frequency different from that of the remaining first valve body 3, so that the air bag 21 can have different lifting frequencies to realize multiple massage modes of the massage system. Further explanation, if the passenger wants to experience a softer massage lifting pressure, the first valve body 3 with a moderate switching frequency can be switched to indirectly inflate the air bag 21; if the passenger wants to experience a more urgent massage lifting pressure, the first valve body 3 with a faster switching frequency can be switched to indirectly inflate the air bag 21. As for the switching mode of the first valve body 3 with different frequencies, it can be manually switched or switched in a certain order according to the program to realize different modes of massage.

[0044] Optionally, the second valve body 4 is configured as at least one memory alloy valve 41, a second gas inlet end 44 of the memory alloy valve 41 being in communication with the first gas outlet end 32 of the first valve body 3, and a gas charging end 42 of the memory alloy valve 41 being in communication with the air bag 21, and in the case of charging the air bag 21 through the first valve body 3, the gas charging passage of the memory alloy valve 41 corresponding to the air bag 21 is always in an open state.

[0045] The memory alloy valve 41 has the characteristics of simple structure and low cost, and the memory alloy wire 43 also has good elasticity and damping property, which can reduce vibration and noise. The specific structure of the memory alloy valve 41 is a routine technical means in the art, and will not be described here. In the following, only the process of the memory alloy valve 41 acting on the air bag 21 is further explained:

[0046] In the case of charging the air bag 21, the gas charging passage of the memory alloy valve 41 is open, and the gas discharging passage of the memory alloy valve 41 is closed; in the case of maintaining the pressure of the air bag 21, both the gas charging passage and the gas discharging passage of the memory alloy valve 41 are in a closed state; in the case of discharging the air bag 21, the gas charging passage of the memory alloy valve 41 is closed, and the gas discharging passage of the memory alloy valve 41 is open; due to the existence of the pressure maintaining state, this operation process is mainly suitable for use on a seat waist support, and the specific selection of the memory alloy valve 41 can be a combination of a two-position three-way valve and a two-position two-way valve (also known as a waist support valve), as shown in FIG. 3.

[0047] In a conventional seat massage system, such as waist and back massage or leg massage, only continuous charging and discharging of the air bag 21 is usually required to reciprocally press and massage the body of the occupant, so the memory alloy valve 41 only needs to have a charging state and a discharging state. The memory alloy valve 41 in the present embodiment is selected as a two-position two-way valve, as shown in FIGS. 1 and 2. In addition, in addition to using the memory alloy valve 41, valves made of other materials can also be used, which are determined according to actual use requirements and cost requirements, and are not limited here.

[0048] Optionally, the present application also proposes a massage system, which is mainly suitable for use on a car seat, including but not limited to realizing waist massage, back massage or leg massage. The massage system includes a gas using assembly 2, a gas source body 1, a control module 5 and the valve body assembly 6 described in the above embodiments, wherein:

[0049] The gas using assembly 2 is in communication with the valve body assembly 6 through a gas path, and the gas using assembly 2 is configured as an air bag 21 capable of realizing pneumatic adjustment of a seat. The air bag 21 is provided in multiple groups, and the arrangement position and arrangement mode of the multiple groups of air bags 21 can be configured according to actual requirements, wherein the arrangement mode of the multiple groups of air bags 21 includes but is not limited to linear arrangement, S-shaped arrangement or annular arrangement, etc.

[0050] The gas source body 1 inflates the air bag 21 through the valve body assembly 6;

[0051] The controller 5 is connected with the air bag 21 and the gas source body 1 respectively, and the gas source body 1 and the valve body assembly 6 are controlled by the controller 5 to inflate or deflate the air bag 21.

[0052] Optionally, the controller 5 can control the gas source body 1 and the valve body assembly 6 to inflate or deflate the air bags 21 in sequence according to a specific timing sequence, and the specific timing sequence should satisfy that the air bags 21 can be lifted in turn; based on the specific timing sequence, when the air bags 21 are arranged in a ring shape, the air bags 21 lifted in turn in sequence can cooperate with the pulse pressing frequency of the valve body assembly 6, so that the passengers can feel the pressing massage feeling of continuous sliding in a certain direction, and the massage effect of seat kneading vibration is realized.

[0053] Further refinement, based on the specific timing sequence, in the case that the current sequence air bag 21 starts to deflate from the saturated state, the next consecutive air bag 21 adjacent to the current sequence air bag 21 continues to inflate; in the case that the deflation amount of the current sequence air bag 21 reaches 20%, the next consecutive air bag 21 continues to inflate to the saturated state and starts to deflate from the saturated state, so that the air bags 21 are inflated and deflated in circulation, and the kneading vibration massage mode with the turn-by-turn trailing effect is realized between the air bags 21.

[0054] Optionally, the gas source body 1 can also be directly connected with a common on-off valve such as an electromagnetic valve 7, the electromagnetic valve 7 can be a combination of a two-position three-way valve and a two-position two-way valve (mainly suitable for a waist support), or a two-position two-way valve (mainly suitable for waist and back massage or leg massage), but is not limited thereto, and the controller 5 controls the gas source body 1 and the electromagnetic valve 7 to inflate or deflate the air bag 21, so that the traditional pneumatic massage is realized, that is, the pneumatic massage mode realized by the valve body assembly 6 in the embodiment can be applied in the automobile seat massage system in combination with the traditional pneumatic massage mode.

[0055] In addition, the embodiment of the application further provides an automobile seat, which comprises a seat body and the above-mentioned massage system, and the massage system is installed on the seat body.
