Description

Technical Field

[0001] The utility model generally relates to the technical field of automobile seat air bags, and in particular to a low-noise massage air bag with a plastic support structure. Background Art

[0002] Airbags are an important component of car seat massage systems, providing massage functions for seats. With the gradual expansion of the automotive consumer market and increasing demand for comfort, users' demands for car seat comfort are also gradually increasing.

[0003] To enhance the massage effect, current massage airbag designs often feature a massage bump on the side closest to the passenger. When the airbag deflates, the massage bump is susceptible to significant collapse due to the force exerted by the passenger. During further inflation, the collapsed massage bump rapidly expands due to its own resilience and air pressure, generating noticeable noise. This repetitive noise significantly impacts the user experience, particularly during repeated inflation and deflation. To reduce this noise, sponges and other contents are often placed within the massage bumps, which are then sealed within the protrusions with a coating to prevent them from collapsing and reduce the noise from the inflation and rebound of the massage bumps. However, this approach is relatively costly. Utility Model Content

[0040] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are intended only to illustrate the relevant utility model and are not intended to limit the scope of the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.

[0041] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0042] Please refer to Figure 1-2 The utility model provides a low-noise massage air bag with a plastic support structure, comprising:

[0043] An airbag body 1 is provided with an air port for exchanging gas with an external air source; the airbag body 1 has an inflated state and a deflated state; the air port is inflated and deflated to switch the airbag body 1 between the inflated state and the deflated state;

[0044] The top of the airbag mother body 1 has at least one protrusion 2 protruding from the airbag mother body 1; a support mechanism for replacing the contents is provided inside the airbag mother body 1 corresponding to the protrusion 2;

[0045] The support mechanism is used to replace the original sponge and other contents, reducing the rebound noise of the bumps while saving costs. The support mechanism can be integrally processed with the airbag diaphragm, or it can be processed separately and then processed on the inner surface of the airbag diaphragm by high-frequency welding or hot pressing;

[0046] The support mechanism has a first air hole 3 for connecting the internal space of the air bag body 1 with the internal space of the protrusion 2;

[0047] When the air bag mother body 1 is in a deflated state, the support mechanism abuts against the inner wall of the protrusion 2, so that an air channel 4 is formed between the support mechanism and the protrusion 2; the air channel 4 connects the first air hole 3 and the internal space of the protrusion 2.

[0048] Specifically, refer to Figure 14 and 15 , the air bag mother body 1 is a single-layer air bag, or a multi-layer air bag connected to each other; Figure 3 and 5 The air bag body 1 has an inflated state and a deflated state.

[0049] This method can prevent the protrusion 2 from being subjected to external forces and causing a large depression when the massage air bag is deflated, so that when the massage air bag is inflated again, gas can enter the protrusion 2 through the first air hole 3 and the airway 4, avoiding the protrusion 2 from expanding rapidly and generating noise.

[0050] refer to Figure 4 , protrusion 2 is subjected to Figure 4 The force in the direction of the arrow in the middle creates a depression. Under the action of the support protrusion 5, an airway 4 is formed. When it is necessary to inflate again, refer to Figure 6 , the gas can enter the interior of the protrusion 2 through the air channel 4. During this process, the rebound amount of the protrusion 2 becomes smaller, and the gas gradually fills the protrusion 2 through the air channel 4; the protrusion 2 is not quickly filled from a completely collapsed state, thus avoiding vibration and noise.

[0051] Furthermore, the support mechanism includes:

[0052] A support plate 5, the support plate 5 being installed inside the airbag body 1 near the protrusion 2;

[0053] A supporting protrusion 6 is provided on the surface of the supporting plate 5 close to the protrusion 2;

[0054] When the airbag mother body 1 is in a deflated state, the supporting protrusion 6 abuts against the inner side wall of the protrusion 2 , so that the air channel 4 is formed between the supporting plate 5 and the protrusion 2 .

[0055] Specifically, the plurality of support protrusions have various arrangements. In this embodiment, the support protrusion portion 6 includes a plurality of support protrusions evenly distributed along the circumference of the first air hole 3. There is a gap between the support protrusion and the edge of the first air hole 3.

[0056] Furthermore, the support protrusions are columnar structures with a certain height, and the heights of the multiple support protrusions can be all equal, partially equal, or completely unequal, and can be set according to actual conditions; Figure 11The heights of the multiple supporting protrusions are not all equal, which is used to expand the airway 4.

[0057] Specifically, the height differences between the different support protrusions make the air channel 4 formed between adjacent support protrusions more stable. When the protrusion 2 is subjected to external force, its inner surface abuts against the support protrusions of different heights, creating additional hollow areas due to the height differences, thereby increasing the cross-section of the air channel 4.

[0058] In some embodiments, reference Figure 7-13 The cross section of the supporting protrusion in the horizontal direction is of any shape, such as rectangle, square, circle, oval, flower, cross or heart shape, etc., which can be processed and formed. It can be used alone or in combination.

[0059] The extending direction of the supporting protrusion may be parallel to the radial direction of the first air hole 3 , or may be perpendicular to the radial direction of the first air hole 3 .

[0060] Specifically, the arrangement of the supporting protrusions in different directions can form a plurality of interconnected air passages 4 on the side of the supporting plate 5 close to the protrusion 2 .

[0061] Furthermore, the plurality of support protrusions are arranged in a single-layer annular array or a multi-layer annular array along the circumference of the first air hole 3. The single-layer annular array is more suitable for air bags with smaller protrusions 2, while the multi-layer annular array is more suitable for air bags with larger protrusions 2.

[0062] This method can provide sufficient support for the protrusion 2 while making the cross-section of the air channel 4 larger, facilitating rapid inflation of more gas, and allowing the protrusion 2 and the inner surface of the airbag mother body 1 to separate from each other without generating noise during the inflation process.

[0063] In order to make the airway 4 less likely to be squeezed and closed, the present invention also makes the following design to the supporting protrusion:

[0064] Some of the supporting protrusions have multiple first protrusions 7 on their side walls, and multiple first grooves 9 are formed between the multiple first protrusions 7. The lengths of two adjacent first protrusions 7 along the extension direction of the support plate 5 surface are equal, so that the cross-section of the supporting protrusion in the horizontal direction forms a flower shape.

[0065] Preferably, the number of the first protrusions may be four or five, so that the cross-section of the supporting protrusion in the horizontal direction forms a four-petal flower shape or a five-petal flower shape; the first groove 9 is connected to the airway 4 for expanding the airway 4.

[0066] Some of the supporting protrusions have multiple second protrusions 8 on their side walls, and second grooves 10 are formed between the multiple second protrusions 8. The lengths of two adjacent second protrusions 8 along the extension direction of the surface of the support plate 5 are not equal, and the lengths of the relatively arranged second protrusions 8 are equal, so that the cross-section of the supporting protrusion in the horizontal direction forms a cross shape; the second groove 10 is connected to the airway 4 and is used to expand the airway 4.

[0067] The above structural design forms a relatively stable air passage 4 on the side of the support plate 5 close to the protrusion 2, and also increases the cross-section of the air passage 4. When the protrusion 2 is subjected to external forces, the air passage 4 will not be squeezed and closed, ensuring that gas can smoothly enter the protrusion 2 during inflation and preventing noise.

[0068] The above description is merely a preferred embodiment of the present invention and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the present invention is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the concept of the present invention. For example, a technical solution formed by replacing the above-mentioned features with (but not limited to) technical features with similar functions disclosed in the present invention.
