Description

Technical Field

[0001] The present application relates to the technical field of beds, and in particular to an airbag, an airbag assembly, a mattress, a bed, and a massage device. Background Art

[0002] With the improvement of people's living standards and the development of network technology, the concept of smart home has become more and more mature, including various home appliances or smart home products such as air conditioners, refrigerators, televisions, mobile phones, rice cookers, smart gateways, etc. Smart home products all have WiFi modules, temperature and humidity sensors, etc., which constitute the overall ecological environment of smart home.

[0003] As a core component of furniture, beds are gradually evolving towards intelligent functionality. Modules like smart Bluetooth modules and speakers are being integrated into smart beds. One of the hottest features of smart beds is the inclusion of airbag components to achieve various functions.

[0004] The airbag components on smart beds on the market are mainly divided into several types. The first type of airbags are arranged individually, and the airbags are separated from each other and do not affect each other. The functions of this type of airbags are relatively simple and less innovative. The second type is stacked to achieve the effect of pushing and stroking, and has relatively more functions.

[0005] In the prior art, if the height of the airbag push needs to be increased, the width of the airbag needs to be increased. In this way, when the airbag changes from an uninflated flat rectangular state to a three-dimensional cylindrical shape after inflation, the diameter of the cylinder, that is, the height of the airbag push-up, can be increased. In this way, the height of the cylinder increases, but the horizontal direction also increases synchronously. This requires that a larger amount of gas needs to be injected to adjust the height of the airbag push-up, which will lead to the problem of slow adjustment speed. Summary of the Invention

[0006] The present application provides an airbag, an airbag assembly, a mattress, a bed and a massage device to solve the problem in the prior art that when the airbag increases the massage height, a large amount of gas needs to be injected, resulting in a slow adjustment speed.

[0012] Furthermore, the distance between the connecting portion and the first side of the airbag is greater than or equal to the distance between the connecting portion and the second side of the airbag.

[0013] Furthermore, the length from the connecting portion to the second side of the airbag accounts for 1 / 8 to 1 / 2 of the length from the first side of the airbag to the second side of the airbag.

[0014] Furthermore, the plurality of sub-airbags include a first sub-airbag and a second sub-airbag, and the connecting portion is located between the first sub-airbag and the second sub-airbag.

[0015] Furthermore, the side surface of the second sub-airbag away from the first sub-airbag has a curved surface.

[0016] Furthermore, the vertical projection area of the first sub-airbag is larger than the vertical projection area of the second sub-airbag, or the vertical projection area of the first sub-airbag is equal to the vertical projection area of the second sub-airbag, or the vertical projection area of the first sub-airbag is smaller than the vertical projection area of the second sub-airbag.

[0017] Furthermore, the connecting portion is one connecting pipeline or multiple connecting pipelines.

[0018] Furthermore, when the connecting portion is one connecting pipeline, the distance between the connecting pipeline and the left and right sides of the airbag is the same; or when the connecting portion is multiple connecting pipelines, the multiple connecting pipelines are evenly spaced in the direction along the left and right sides of the airbag.

[0019] In the second aspect, the present application provides an airbag assembly, comprising multiple airbags, which are the above-mentioned airbags, the airbags are stacked, and the length of the airbag assembly in the direction from the first side of the airbag to the second side of the airbag is greater than the length of a single airbag from the first side edge of the airbag to the second side edge of the airbag; and / or the airbags are clamped, and the length of the airbag assembly in the direction from the first side of the airbag to the second side of the airbag is greater than the length of a single airbag from the first side edge of the airbag to the second side edge of the airbag.

[0020] Furthermore, in the airbag assembly, in a direction from the first side of the airbag to the second side of the airbag, the overlapping length of adjacent airbags is between 1 / 4 and 2 / 3.

[0021] Furthermore, when the airbags are stacked, adjacent rear airbags are stacked on top of the front airbags, and / or adjacent front airbags are stacked on top of the rear airbags.

[0022] Furthermore, the multiple airbags are flexibly connected.

[0023] In a third aspect, the present application provides a mattress, which includes an airbag assembly, and the airbag assembly is the above-mentioned airbag assembly.

[0037] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0038] like Figures 1 to 5 As shown, an airbag of this embodiment includes: a plurality of sub-airbags 10 and a connecting portion 20. The sub-airbags 10 are stacked, and a connecting portion 20 is provided between adjacent sub-airbags 10 to connect the sub-airbags 10.

[0039] The technical solution of this embodiment is that the airbag includes multiple sub-airbags 10, and each sub-airbag 10 is connected by a connecting portion 20. In this way, when one sub-airbag 10 is inflated, the remaining sub-airbags 10 can also be filled with gas. The sub-airbags 10 are stacked in a stacked manner. Such an airbag structure can increase the height of the airbag after inflation, without increasing the width of the airbag to increase the height of the airbag. The above structure can increase the pushing and stroking height of the airbag without changing the structure of the mattress or bed. The technical solution of this embodiment effectively solves the problem in the prior art that the airbag needs to be injected with a large amount of gas when increasing the pushing and stroking height, resulting in a slow adjustment speed.

[0040] It should be noted that the airbags 10 are stacked in the thickness direction of the bed. In this embodiment, the stacking is on top of each other. The connecting portion 20 has a preset extension distance in the thickness direction of the bed. This facilitates the arrangement and combination of the airbags when used in combination, such as the use of multiple airbags in a clamped combination. The airbags 10 of this embodiment are not simply stacked. The airbags 10 and the connecting portion 20 of this embodiment are integrally formed, or are connected and fixed by bonding, riveting, sewing, welding, or other methods.

[0041] like Figure 1As shown, in the technical solution of this embodiment, when the airbag is inflated, the height of the first side of the airbag is greater than the height of the second side of the airbag. This facilitates subsequent combination configurations, such as stacking multiple airbags, clamping arrangements, and other structures. This combination of airbags can improve human comfort and provide greater flexibility, meeting the needs of people of different weights, genders, and heights. There are various ways to achieve a greater height of the first side of the airbag than the second side, such as by having the second sub-airbag 12 tilt upward.

[0042] like Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, the length of the first side of the connecting portion 20 is greater than the length of the second side of the connecting portion 20, the first side of the connecting portion 20 is consistent with the first side of the airbag, and the second side of the connecting portion 20 is consistent with the second side of the airbag. There are many ways to implement that the height of the first side of the airbag is greater than the height of the second side of the airbag. This embodiment satisfies the requirement that the height of the first side of the airbag is greater than the height of the second side of the airbag by setting the length of the first side of the connecting portion 20 to be greater than the length of the second side of the connecting portion 20. Such a structure facilitates the combination of multiple airbags, such as placing the airbags in the gaps between the sub-airbags. The first side of the connecting portion 20 here specifically refers to the front of the connecting portion 20, and the second side of the connecting portion 20 specifically refers to the rear of the connecting portion 20. The distance from the front of the connecting portion 20 to the rear of the connecting portion 20 decreases linearly. As those skilled in the art can understand, when the number of the multiple sub-airbags 10 is two, there is one connecting portion 20, and when the number of the multiple sub-airbags 10 is three, there are two connecting portions 20, such as Figure 3 As shown, when the number of the plurality of sub-airbags 10 is four, the number of the connecting portions 20 is three, and so on, which will not be repeated here.

[0043] like Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, the distance between the connecting portion 20 and the first side of the airbag is greater than or equal to the distance between the connecting portion 20 and the second side of the airbag. This structure allows the airbags to have a larger mating area when assembled, and the mating between the airbags is stable.

[0044] like Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, the length from the connecting portion 20 to the second side of the airbag accounts for 1 / 8 to 1 / 2 of the length from the first side of the airbag to the second side. This allows for a more stable fit during assembly; for example, when the airbags are clamped together, the fit area is larger. As a more preferred embodiment, the length from the connecting portion 20 to the second side of the airbag accounts for 1 / 4 to 1 / 3 of the length from the first side of the airbag to the second side.

[0045] like Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, the multiple sub-airbags 10 include a first sub-airbag 11 and a second sub-airbag 12, and the connecting portion 20 is located between the first sub-airbag 11 and the second sub-airbag 12. The structure of the two sub-airbags is not prone to misalignment when combined, has low processing costs, and is easy to set up.

[0046] like Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, the side of the second sub-airbag 12 facing away from the first sub-airbag 11 has a curved surface. The smooth curved transition enhances the human body feel. Specifically, the second sub-airbag 12 gradually contracts and thins from a certain position in the middle to the first side of the second sub-airbag 12, and then gradually contracts and thins from a corresponding position in the middle of the second sub-airbag 12 to the second side of the second sub-airbag 12.

[0047] like Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, the vertical projection area of the first sub-airbag 11 is equal to the vertical projection area of the second sub-airbag 12. The area of the first sub-airbag 11 is the same as the area of the second sub-airbag. Such a structure has strong adaptability. Generally speaking, it can meet the requirements of stability and the requirements of pushing and stroking. As other feasible implementation methods, the vertical projection area of the first sub-airbag 11 is larger than the vertical projection area of the second sub-airbag 12, that is, the area of the lower sub-airbag is larger. Such an airbag is more stable, that is, the first sub-airbag 11 is set to be larger than the second sub-airbag 12. This is because the bottom support of the airbag is stable, and the top airbag is smaller at this time, which will give the human body greater pressure, and the pushing and stroking force experienced will be greater. Other implementations may also be that the projection area of the first sub-airbag 11 in the vertical direction is smaller than the projection area of the second sub-airbag 12 in the vertical direction. Such a structure makes the pushing and stroking area of the airbag larger. The first sub-airbag 11 is set to be smaller than the second sub-airbag 12, so that the bottom airbag can form a structure similar to a seesaw. At this time, when the human body lies on top of the airbag, the airbag can move in one direction together according to the body position adjustment of the human body.

[0048] like Figure 1 and Figure 2As shown, in the technical solution of this embodiment, the connecting portion 20 is a connecting pipe or multiple connecting pipes. This structure is convenient to set up. The connecting portion 20, the first sub-airbag 11, and the second sub-airbag 12 are made of the same material and are an integrally molded structure in this embodiment. In the technical solution of this embodiment, the first sub-airbag 11, the second sub-airbag 12, and the connecting portion 20 can be made of TPU (thermoplastic polyurethane elastomer rubber) material, rubber material, etc.

[0049] like Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, when the connecting portion 20 is a connecting pipe, the connecting pipe is at the same distance from the left and right sides of the airbag. This structure ensures that the airbag is subjected to relatively uniform force. The connecting pipe can be arranged so that it runs from the left side of the airbag to the right side. This structure makes the connecting pipe structure more robust, allows the airbag to withstand relatively large forces, and distributes the forces more evenly, making the connecting pipe less susceptible to clogging. For example, when a person presses on the airbag, the connecting pipe is prone to clogging due to pressure, requiring a higher gas pressure. Of course, the connecting pipe can also be arranged so that the distance from the left side of the airbag to the right side of the airbag is the same, which ensures balanced force on the airbag. It should be noted that if the distance from the left side of the airbag to the right side of the airbag is larger than the distance from the right side of the airbag, a larger gap will appear at the edge, reducing comfort. The shape of the connecting pipe is similar to a rectangle. The first sub-airbag 11 and the second sub-airbag 12 also have a similar rectangular shape when there is no gas. When the connecting portion 20 is a plurality of connecting pipes, the plurality of connecting pipes are evenly spaced from the left side to the right side of the airbag.

[0050] In the technical solution of this embodiment, the first side of the airbag is the front of the airbag, and the second side of the airbag is the rear of the airbag. The first side of the airbag, the first side of the first sub-airbag 11, and the first side of the second sub-airbag 12 are oriented in the same direction. The second side of the airbag, the second side of the first sub-airbag 11, and the second side of the second sub-airbag 12 are oriented in the same direction. The inflation port of the airbag is located on the side of the first sub-airbag 11 away from the second sub-airbag 12. When the airbag is not inflated, the first sub-airbag 11 and the second sub-airbag 12 overlap.

[0051] like Figure 4 and Figure 5 As shown, the present application also provides an airbag assembly 100 comprising multiple airbags. The airbags are the aforementioned airbags, stacked one on top of the other, and the length of the airbag assembly 100 from the first side to the second side of the airbag is greater than that of a single airbag from the first side to the second side of the airbag. This combination of airbags allows for a more coherent and smooth massage, without any sense of interruption or fragmentation.

[0052] It should be noted that the left and right sides of each airbag are flush in the vertical direction, and the airbags can be stacked in such a way that there are two airbags stacked in the vertical direction, or three airbags stacked in the vertical direction, or four airbags stacked in the vertical direction, or even more.

[0053] The airbag assembly 100 is stacked, with the front portion stacked and the back portion pressed. For example, the second airbag is placed on top of the first airbag, with the front portion of the second airbag overlapping the rear portion of the first airbag; the third airbag is placed on top of the second airbag, with the rear portion of the second airbag overlapped and pressed by the third airbag. The second airbag is thus "stacked on top of the first airbag and pressed by the third airbag," and the arrangement continues in this manner. Alternatively, the second airbag can be placed below the first airbag, with the front portion of the second airbag overlapping and the rear portion of the first airbag; the third airbag is placed below the second airbag, with the rear portion of the second airbag overlapped and pressed by the third airbag. This arrangement is also within the scope of protection of this patent. The stacked airbags form a stepped structure, with the front and rear airbags offset and the left and right sides of the airbags flush.

[0054] It should be noted that the airbag of this embodiment can be used alone if necessary, that is, the structure of one airbag forms an airbag assembly.

[0055] As another embodiment, the airbag is clamped, and the length of the airbag assembly 100 in the direction from the first side of the airbag to the second side of the airbag is greater than the length of a single airbag from the first side of the airbag to the second side of the airbag. The specific structure of the airbag clamping arrangement can be: taking a plurality of sub-airbags including a first sub-airbag 11 and a second sub-airbag 12 as an example, the connecting portion 20 is arranged between the first sub-airbag 11 and the second sub-airbag 12, the portion of the connecting portion 20 to the first sub-airbag 11 on the first side of the airbag is the front section of the first sub-airbag, the portion of the connecting portion 20 to the first sub-airbag 11 on the second side of the airbag is the rear section of the first sub-airbag, the portion of the connecting portion 20 to the second sub-airbag 12 on the first side of the airbag is the front section of the second sub-airbag, and the portion of the connecting portion 20 to the second sub-airbag 12 on the second side of the airbag is the rear section of the second sub-airbag. The connecting portion 20 divides the first sub-airbag 11 and the second sub-airbag 12 into two parts, front and back, which facilitates the combination of the airbags into the combination form of the airbag assembly 100. The front section of the first sub-airbag and the front section of the second sub-airbag clamp the adjacent airbags. The front section of the first sub-airbag and the front section of the second sub-airbag overlap in the vertical direction of space to form a clamping arm. The adjacent airbag located on the first side of the airbag is inserted into the clamping arm formed by the front section of the first sub-airbag and the front section of the second sub-airbag (that is, except for the first airbag, the airbags in the middle are all in the form of inner containment and outer packaging). Such a matching structure makes the combination of the airbags more stable. The upper surface of the front section of the first sub-airbag and the outer wall surface of the adjacent airbag form a friction surface, and the lower surface of the front section of the second sub-airbag and the outer wall surface of the adjacent airbag form a friction surface. In this way, the two airbags are not prone to misalignment, detachment, etc. The front section of the first sub-airbag and the front section of the second sub-airbag clamp the two side surfaces of the adjacent airbag. The two side surfaces refer to the upper and lower side surfaces. Such a matching structure makes the matching between the airbags more stable.

[0056] Of course, other embodiments may include the first and second sub-airbag front segments clamping the first sub-airbag rear segment of an adjacent airbag, or the first and second sub-airbag front segments clamping the second sub-airbag rear segment of an adjacent airbag. Alternatively, any two-by-two combinations or any combination of the three aforementioned coordination methods may be used. This structural combination is more flexible, allowing for appropriate combinations based on the varying sensitivity of various parts of the human body. In other embodiments, both stacking and clamping airbags may be used together within the same airbag assembly.

[0057] like Figure 4 and Figure 5 As shown, in the technical solution of this embodiment, the airbag assembly 100 has an overlap length of between 1 / 4 and 2 / 3 of the length along the direction from the first side of the airbag to the second side of the airbag. This stacking of the airbags ensures both the consistency of the airbag push and stroke and the stability and integrity of the airbag.

[0058] like Figure 4 and Figure 5 As shown, in the technical solution of this embodiment, when the airbags are stacked, the adjacent rear airbags are stacked on top of the front airbags, and / or the adjacent front airbags are stacked on top of the rear airbags. The above structure is convenient to set up and can achieve various pushing and stroking forms.

[0059] In the technical solution of this embodiment (not shown), multiple airbags are flexibly connected. This makes the structure of the airbag assembly 100 more stable and less prone to problems such as misalignment and deformation. The flexible connection provides a better sense of comfort.

[0060] This application also provides a mattress comprising an airbag assembly 100, which is the aforementioned airbag assembly 100. Such a mattress provides more consistent massage, better integrity, and greater stability. The airbag has a fixing portion for securing the airbag to the airbag support fabric.

[0061] The present application also provides a bed, including a mattress, such as the aforementioned mattress. The bed of the present application provides a relatively consistent massage. Its multifunctionality is primarily reflected in its ability to massage different parts of the body from head to toe, creating a wave-like floating massage sensation. It can also individually massage the waist and neck, legs, and buttocks.

[0062] The present application also provides a massage device, comprising an airbag, wherein the airbag is the above-mentioned airbag.
