Specific embodiments

[0034] In order to more clearly understand the above-mentioned objectives, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application can also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present application, not all of the embodiments.

[0036] With the continuous development of intelligent cockpits in cars, users have an increasing demand for the comfort and functionality of car seats. For the seats of existing models on the market, multiple air bags are generally used for seat massage, or for both seat massage and hardness adjustment functions. However, this type of seat cushion that uses multiple air bags for both hardness adjustment and massage cannot achieve simultaneous hardness adjustment and massage, and cannot meet the needs of many users.

[0037] Based on this, this embodiment provides a massage cushion, seat, and vehicle, wherein the first airbag is a massage airbag and the second airbag is a hardness adjustment airbag. When the first airbag deforms in a first direction, it can directly change the pressure exerted on the massaged object by the first airbag, thereby achieving a massage effect. The second airbag can adjust its own air pressure without deforming itself, thereby changing its own support strength in the first direction, thereby achieving hardness adjustment. Alternatively, the second airbag can adjust its own air pressure while deforming in the first direction, thereby also changing its own support strength in the first direction, thereby achieving hardness adjustment. By arranging at least part of the first side of the first airbag against the second side of the second airbag in the first direction, after the occupant sits on the seat cushion body, the second airbag can adjust the hardness while also utilizing the first airbag to achieve the purpose of massage. Moreover, when the second airbag is inflated and pressure-maintaining, that is, when the massage cushion is adjusted to hardness, the first airbag located on the second airbag can directly receive support from the second airbag, 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:

[0038] 1 to 3 , 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 a first direction, the first air bag 11 and the second air bag 12 both have a first side and a second side. The first side of the first air bag 11 and the first side of the second air bag 12 are both sides facing the support surface of the cushion body 1, and the second side of the first air bag 11 and the second side of the second air bag 12 are both sides facing away from the support surface of the cushion body 1. At least part of the second side of the first air bag 11 is in contact with the first side of the second air bag 12. The first air bag 11 and the second air bag 12 can both be deformed by inflation and deflation in the first direction. The plurality of first air bags 11 and the second air bags 12 are all arranged in the cushion body 1. The projection area of ​​the second air bag 12 in the first direction is larger than the projection area of ​​the first air bag 11, and the projection of at least part 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.

[0039] The massage cushion provided by this embodiment has the first air bag 11 as a massage air bag and the second air bag 12 as a hardness adjustment air bag. When the first air bag 11 is deformed in the first direction, it can directly change the pressure on the object being massaged from the first air bag 11, thereby achieving a massage effect; wherein, the second air bag 12 can change its own supporting force in the first direction by adjusting its own air pressure without deforming itself, thereby achieving hardness adjustment, or the second air bag 12 can also change its own support force in the first direction by adjusting its own air pressure while deforming in the first direction, thereby achieving hardness adjustment. The supporting force in one direction is realized, thereby realizing hardness adjustment; by making the first side of at least part of the first air bag 11 counteract the second side of the second air bag 12 in the first direction, after the occupant sits on the seat cushion body 1, the second air bag 12 can use the first air bag 11 to complete the massage purpose while adjusting the hardness; moreover, when the second air bag 12 is inflated and pressure-maintained, that is, after the massage cushion is hardened, 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.

[0040] Continuing with reference to Figures 1 and 2, in the first direction, at least portions of the second sides of the two first air bags 11 abut against 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 at least portions of three, four or even more first air bags 11 may be connected to the second air bags 12; thereby, by controlling the changes in the inflation and deflation states of each first air bag 11, a variety of massage modes are formed on the second air bag 12, further improving the comfort and practicality of the massage cushion.

[0041] Continuing with reference to Figures 1 and 2, in the first direction, the projection of the two first air bags 11 is located within the projection of the second air bag 12; that is, in the first direction, the two first air bags 11 are completely located within the projection range of the second air bag 12; thereby ensuring that the two first air bags 11 can obtain more comprehensive and stable support from the second air bag 12 during massage work, and are less likely to be offset, etc., and the massage method of the two first air bags 11 is also easier to control; it should be understood that three, four or even more first air bags 11 can be completely located within the projection range of the second air bag 12 in the first direction, thereby forming more massage methods above the second air bag 12.

[0042] Continuing with reference to Figures 1 and 2, the number of second air bags 12 and the number of first air bags 11 are both two, and the two second air bags 12 and the two first air bags 11 are arranged in one-to-one correspondence; in the first direction, at least part of the second sides of the two first air bags 11 are in contact with the first sides of the corresponding second air bags 12; the two second air bags 12 are arranged in the second direction, and the second direction is perpendicular to the first direction.

[0043] In some embodiments, an avoidance portion 14 is formed between the two second air bags 12, and the avoidance portion 14 is located in the middle position of the seat cushion body 1. A fan 15 is provided in the avoidance portion 14, and the fan 15 is connected to the two first air bags 11 and the two second air bags 12 respectively through at least four valves; that is, the fan 15 can individually control the inflation and deflation actions of each first air bag 11 and the second air bag 12.

[0044] Continuing with reference to Figure 1, the massage cushion also includes at least one third air bag 13 that can be inflated and deflated in a first direction. At least one third air bag 13 is arranged in a third direction with the first air bag 11. The third direction is perpendicular to the second direction, and the third direction is perpendicular to the first direction. The second direction and the third direction can be located in a first plane, and the first plane is parallel to the support surface on the cushion body 1. Among them, the third air bag 13 has the same function as the first air bag 11, and both are massage air bags. In the first direction, the projection of the third air bag 13 does not intersect with the projection of the second air bag 12. Adding the third air bag 13 can utilize the separate control of the first air bag 11, the second air bag 12 and the third air bag 13 to form more massage methods.

[0045] Continuing with FIG1 , at least one third air bag 13 and a plurality of first air bags 11 are arranged in an array in the second and third directions. Specifically, they can be arranged in a rectangular array, or in a circular, annular, fan-shaped or other pattern; thereby enabling more comprehensive coverage of the massage area and ensuring a better massage effect.

[0046] Continuing with reference to Figures 1 and 2, one or more third air bags 13 can be deformed by inflation and deflation in the fourth direction, and the fourth direction forms a set angle with the first plane; the third air bag 13 can be arranged at an angle to the support surface, as long as the third air bag 13 can change the supporting force of the support surface at the position where the third air bag 13 is placed when inflating and deflation. In other words, the third air bag 13 can be arranged at an angle according to the installation position or the frame structure inside the massage cushion, as long as it does not affect the massage effect; specifically, there are four third air bags 13 and two first air bags 11, and the two first air bags 11 and the four third air bags 13 are arranged in a matrix of two columns and three rows; the four third air bags 13 are arranged adjacent to each other, and two of the third air bags 13 adjacent to the first air bag 11 are arranged at an angle along the fourth direction; at this time, at least four massage modes can be achieved, namely pulse massage, wave massage, circular massage and butterfly massage.

[0047] In some embodiments, a seat cushion suspension spring 4 is also included. After all the air bags are connected into an assembly structure, they can be connected to the seat body 3 through the seat cushion suspension spring 4. The seat cushion suspension spring 4 can provide elastic force in the first direction for the assembly structure formed by all the air bags, which can not only support the air bags, but also further improve the riding comfort of the passengers; the seat cushion suspension spring 4 can be specifically connected to the seat body 3 through multiple hooks around it, which can make subsequent maintenance and disassembly work more convenient.

[0048] In some embodiments, a limit frame is provided on the outer side of the first airbag 11 and / or the second airbag 12; the setting of the limit frame can prevent the first airbag 11 and / or the second airbag 12 from excessive deformation, and can also assist the first airbag 11 and / or the second airbag 12 to complete the inflation and deflation action more smoothly and evenly, and play a guiding and plastic role in the deformation of the first airbag 11 and / or the second airbag 12.

[0049] In some embodiments, in the first direction, the second side of at least a portion of the first air bag 11 is first connected to the second air bag 12 through a force transmission medium; wherein the force transmission medium can be made of foam, sponge, plastic, rubber or other materials, as long as the first air bag 11 can be supported by the inflated second air bag 12 during massage.

[0050] Continuing with reference to Figures 1 to 3, in the first direction, at least a portion of the second side of the first airbag 11 is fixedly connected to the first side of the second airbag 12; that is, 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 the two can directly generate an interaction force in the first direction on each other when inflation and deflation deformation occur.

[0051] Continuing with reference to Figure 3, the massage cushion also includes a non-woven fabric 2, which includes a first connecting block 21 and a second connecting block 22. The first air bag 11 is welded to the first connecting block 21, and the second air bag 12 is welded to the second connecting block 22. In the first direction, at least part of the projection of the first air bag 11 is located within the projection of the second air bag 12. The non-woven fabric 2 can be sleeved on the outside of the second air bag 12, and then the first air bag 11 is fixed on one of the side surfaces of the non-woven fabric 2, so that the relative position of the first air bag 11 and the second air bag 12 is more stable. The first air bag 11 can also be connected to the second air bag 12 through other media, such as metal plates, woven covers and other structures, as long as the relative position of the first air bag 11 and the second air bag 12 can be guaranteed to be stable, and the force transmission between the second air bag 12 and the first air bag 11 can be prevented.
