DETAILED DESCRIPTION

[0032] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0034] With the continuous development of intelligent automotive cockpits, users have an increasing demand for the comfort and functionality of in-car seats. For the seats of existing models on the market, multiple air bags are generally used for seat cushion massage, or for seat cushion massage and hardness adjustment functions at the same time. However, this type of seat cushion that uses multiple air bags to take into account both hardness adjustment and massage cannot achieve simultaneous hardness adjustment and massage, and cannot meet the needs of many users.

[0035] Based on this, the present embodiment provides a massage cushion, a seat and a vehicle, wherein the first air bag is a massage air bag, and the second air bag is a hardness adjustment air bag. When the first air bag is deformed in the first direction, the pressure on the massaged object from the first air bag can be directly changed, thereby achieving a massage effect; wherein the second air bag can adjust its own air pressure without deforming itself, thereby changing its own support strength in the first direction, thereby achieving hardness adjustment, or the second air bag can adjust its own air pressure while deforming in the first direction, thereby changing its own support strength in the first direction, thereby achieving hardness adjustment; by setting the first side of at least part of the first air bag against the second side of the second air bag in the first direction, after the occupant sits on the cushion body, the second air bag can adjust the hardness while also using the first air bag to complete the massage work; and, when the second air bag is inflated and pressure-maintained, that is, after the massage cushion is hardened, the first air bag located on the second air bag can directly obtain the support of the second air bag, thereby making the massage effect more obvious and significantly improving the comfort of the massage cushion. The following is a detailed description of this through specific embodiments:

[0036] Reference Figures 1 to 3As shown in the figure, a massage cushion provided in this embodiment includes a cushion body 1; a plurality of first air bags 11; and a second air bag 12. In the first direction, both the first air bag 11 and the second air bag 12 have a first side and a second side. The first sides of the first air bag 11 and the second air bag 12 are both on the side facing the support surface of the cushion body 1, and the second sides of the first air bag 11 and the second air bag 12 are both on the side facing away from the support surface of the cushion body 1. At least part of the second side of the first air bag 11 abuts against the first side of the second air bag 12; wherein, both the first air bag 11 and the second air bag 12 can undergo inflation and deflation deformation in the first direction; the plurality of first air bags 11 and the second air bag 12 are both arranged in the cushion body 1; the projected area of the second air bag 12 in the first direction is larger than the projected area of the first air bag 11, and at least part of the projection of the second air bag 12 in the first direction overlaps with the projection of the first air bag 11; the first direction refers to the direction perpendicular to the support surface on the cushion body 1.

[0037] In the massage cushion provided in this embodiment, the first air bag 11 is a massage air bag, and the second air bag 12 is a hardness adjustment air bag. When the first air bag 11 undergoes deformation in the first direction, it can directly change the pressure exerted on the object to be massaged by the first air bag 11, thereby achieving the massage effect; wherein, the second air bag 12 can adjust its own air pressure without itself undergoing deformation, thereby changing its own supporting force in the first direction, and thus achieving hardness adjustment. It can also be that the second air bag 12 undergoes deformation in the first direction while adjusting its own air pressure, and can also change the supporting force of the second air bag 12 itself in the first direction, and thus achieve hardness adjustment; by setting at least part of the first side of the first air bag 11 to abut against the second side of the second air bag 12 in the first direction, after the occupant sits on the cushion body 1, while the second air bag 12 adjusts the hardness, it can also use the first air bag 11 to complete the purpose of the massage work; moreover, in the state where the second air bag 12 is inflated and kept under pressure, that is, after the massage cushion is adjusted to be hard, the first air bag 11 located on the second air bag 12 can directly obtain the support of the second air bag 12, thereby making the massage effect more obvious and significantly improving the comfort of the massage cushion.

[0038] Continue to refer to Figure 1 and Figure 2 As shown in the figure, in the first direction, at least part of the second sides of the two first air bags 11 are both in contact with the first side of the second air bag 12; the two first air bags 11 are arranged in the second direction, and the second direction is perpendicular to the first direction; it should be understood that it can also be that at least part of three, four or even more first air bags 11 are all connected to the second air bag 12; thereby, by controlling the change of the inflation and deflation state of each first air bag 11, various massage methods can be formed on the second air bag 12, further improving the comfort and practicality of the massage cushion.

[0039] Continue to refer to Figure 1 and Figure 2 As shown, in the first direction, the projections of the two first airbags 11 are located within the projection of the second airbag 12; that is to say, in the first direction, the two first airbags 11 are completely located within the projection range of the second airbag 12; thus, it can be ensured that these two first airbags 11 can obtain more comprehensive and stable support from the second airbag 12 during the massage operation, and it is not easy to deviate, etc. The massage methods of these two first airbags 11 are also easier to control; it should be understood that there can also be three, four or even more first airbags 11 completely located within the projection range of the second airbag 12 in the first direction, so as to form more massage methods above the second airbag 12.

[0040] Continue to refer to Figure 1 and Figure 2 As shown, the number of the second airbags 12 and the number of the first airbags 11 are both two, and the two second airbags 12 and the two first airbags 11 are arranged in one-to-one correspondence; in the first direction, at least part of the second sides of the two first airbags 11 are in contact with the first sides of the corresponding second airbags 12; the two second airbags 12 are arranged in the second direction, and the second direction is perpendicular to the first direction.

[0041] In some embodiments, an avoidance portion 14 is formed between the two second airbags 12. The avoidance portion 14 is located at the middle position of the seat cushion body 1. A blower 15 is provided in the avoidance portion 14. The blower 15 is communicated with the two first airbags 11 and the two second airbags 12 through at least four valves respectively; that is to say, the blower 15 can independently control the inflation and deflation actions of each first airbag 11 and second airbag 12.

[0042] Continue to refer to Figure 1 As shown, the massage seat cushion further includes at least one third airbag 13 that can undergo inflation and deflation deformation in the first direction. At least one third airbag 13 is arranged with the first airbag 11 in the third direction. The third direction is perpendicular to the second direction, the third direction is perpendicular to the first direction, and the second direction and the third direction can be located in the first plane. The first plane is parallel to the support surface on the seat cushion body 1; wherein, the third airbag 13 has the same function as the first airbag 11, and both are massage airbags. In the first direction, the projection of the third airbag 13 does not intersect with the projection of the second airbag 12. Adding the third airbag 13 can utilize the separate control of the first airbag 11, the second airbag 12 and the third airbag 13 to form more massage methods.

[0043] Continue to refer to Figure 1As shown, at least one third airbag 13 and a plurality of first airbags 11 are arranged in an array in the second direction and the third direction. Specifically, they can be arranged in a rectangular array, or can also be arranged according to patterns such as circular, annular, and fan-shaped; thus, it is possible to provide a more comprehensive coverage of the massage area and ensure a better massage effect.

[0044] Continue to refer to Figure 1 and Figure 2 As shown, one or more of the third airbags 13 can undergo inflation and deflation deformation in the fourth direction, and the fourth direction forms a set angle with the first plane; the third airbag 13 can be inclined with respect to the support surface, as long as it is ensured that the third airbag 13 can change the support force of the support surface at the position where the third airbag 13 is placed during inflation and deflation. That is to say, the third airbag 13 can be arranged obliquely according to the installation position or the frame structure inside the massage cushion, as long as the massage effect is not affected; specifically, the number of the third airbags 13 is four, and the number of the first airbags 11 is two. The two first airbags 11 and the four third airbags 13 are arranged in a matrix of two columns and three rows; the four third airbags 13 are arranged adjacent to each other, and two of the third airbags 13 adjacent to the first airbag 11 are arranged obliquely in the fourth direction; at this time, at least four massage modes can be realized, namely pulse massage, wave massage, cyclic massage, and butterfly massage.

[0045] In some embodiments, it further includes a seat cushion spring 4. After all the airbags are connected into an integrated structure, they can be connected to the seat body 3 through the seat cushion spring 4. The seat cushion spring 4 can provide an elastic force in the first direction for the integrated structure formed by all the airbags, which can not only support the airbags but also further improve the riding comfort of the occupant; specifically, the seat cushion spring 4 can be connected to the seat body 3 through a plurality of hooks around it, so as to facilitate the later maintenance and disassembly work.

[0046] In some embodiments, a limiting frame is provided on the outer side of the first airbag 11 and / or the second airbag 12; through the setting of the limiting frame, it is possible to prevent the first airbag 11 and / or the second airbag 12 from forming excessive deformation, and at the same time, it can also assist the first airbag 11 and / or the second airbag 12 to complete the inflation and deflation actions more gently and evenly, playing a guiding and plastic role in the deformation of the first airbag 11 and / or the second airbag 12.

[0047] In some embodiments, in the first direction, at least a part of the second side of the first airbag 11 is connected to the first of the second airbag 12 through a force transmission medium; wherein, the force transmission medium can be made of materials such as foam, sponge, plastic, rubber, etc., as long as it can enable the first airbag 11 to be supported by the second airbag 12 in an inflated state during massage.

[0048] Continue to refer to Figures 1 to 3As shown, in the first direction, at least a part of the second side of the first airbag 11 is fixedly connected to the first side of the second airbag 12; that is to say, the surface of the first airbag 11 facing the second airbag 12 can be directly connected to the surface of the second airbag 12 facing the first airbag 11, and when they undergo inflation and deflation deformation, they can directly generate a mutual force in the first direction on each other.

[0049] Continue to refer to Figure 3 As shown, the massage cushion further includes a non-woven fabric 2. The non-woven fabric 2 includes a first connecting block 21 and a second connecting block 22. The first airbag 11 is welded to the first connecting block 21, and the second airbag 12 is welded to the second connecting block 22; in the first direction, at least a part of the projection of the first airbag 11 is located within the projection of the second airbag 12; wherein, the non-woven fabric 2 can be sleeved on the outside of the second airbag 12, and then the first airbag 11 is fixed on one side of the non-woven fabric 2; to make the relative positions of the first airbag 11 and the second airbag 12 more stable; the first airbag 11 can also be connected to the second airbag 12 through other media, such as a metal plate, a woven fabric sleeve, etc. As long as the relative positions of the first airbag 11 and the second airbag 12 can be ensured to be stable and the force transmission between the second airbag 12 and the first airbag 11 is not hindered.

[0050] In a second aspect, the present application provides a seat, including the above massage cushion, and further including a seat body 3. The seat body 3 has a first supporting portion 31 for supporting the buttocks, and the massage cushion is provided inside the first supporting portion 31.
