Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of automobile seat accessories, and particularly relates to a pneumatic massage mechanism for an automobile seat and the automobile seat. BACKGROUND

[0002] With the increasing demand for high-end and comfort in automobile consumption, seat systems with pneumatic massage and heating functions have gradually become an important part of vehicle configuration. In the prior art, such seats usually include a pneumatic massage unit and a multi-layer cushion structure, such as a soft layer, a heating layer, and a cladding layer, etc., which is arranged between the interface of the pneumatic massage unit and the human body.

[0003] However, while providing seating comfort and heating functions, the multi-layer cushion structure also significantly affects the force transmission efficiency of the pneumatic massage unit. Specifically, when the massage air bag is inflated to form an inflated high point, the concentrated force generated by the inflated high point is affected by the material deformation and stress distribution characteristics during transmission to the human body through the cushion structure, resulting in the peak pressure being buffered and dispersed, thereby weakening the local strength and accuracy of the massage. As a result, the actual massage perception intensity is reduced, the profile of the wave or point massage is blurred, effective muscle stimulation is difficult to achieve, and the overall driving experience is affected.

[0004] Therefore, it is necessary to propose a technical solution that can optimize the cushion structure and enhance the massage force transmission efficiency in view of the above-mentioned problems existing in the force transmission process of the existing pneumatic massage mechanism. SUMMARY

[0005] In order to solve the above-mentioned problems in the prior art, the present application provides a pneumatic massage mechanism for an automobile seat and the automobile seat.

[0006] In order to solve the above-mentioned technical problems, the technical solution provided by the present application is as follows:

[0008] a pneumatic massage unit comprising a massage air bag;

[0009] a force transmission layer arranged on the side of the pneumatic massage unit close to the human body for contacting the human body;

[0025] Further, the through structure is arranged as one or more of a diamond pattern, a wave pattern, a radial pattern, a rice pattern, a cross pattern, a circular hole, and an oblong hole.

[0032] The present solution can achieve the following technical effects:

[0033] Firstly, the weakening zone of the force transmission layer forms a controllable stress release channel.

DETAILED DESCRIPTION

[0049] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

[0050] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative labor are within the scope of protection of the present application.

[0051] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0052] The following will be described in detail Figures 1-13 The pneumatic massage mechanism for an automobile seat provided in the present embodiment will be described in detail.

[0053] Embodiment One

[0054] The present embodiment provides a pneumatic massage mechanism for an automobile seat, comprising a pneumatic massage unit and a force transmission layer, the pneumatic massage unit comprising a massage air bag 110; the force transmission layer is arranged on the side of the pneumatic massage unit close to the human body for contacting the human body; as shown in Figure 1

[0055] The weakening area 20 is arranged on the force transmission layer, and the weakening area 20 corresponds to the area where the massage air bag 110 is acted on for massage, and the force of the weakening area 20 on the high point of the expansion of the massage air bag 110 is less than the force of other areas of the force transmission layer on the massage air bag 110.​

[0056] The core of the above-mentioned pneumatic massage mechanism lies in that a region with weakened mechanical properties is arranged at a position corresponding to the action region of the massage air bag 110 in the force transmission layer. This design optimizes the transmission path of the massage energy by regulating the structural stiffness distribution of the cushion, and produces a number of beneficial technical effects.

[0057] Firstly, the weakened region 20 of the force transmission layer forms a controllable stress release channel. When the massage air bag 110 is inflated and expands, the weakened region 20 becomes the region where deformation is concentrated due to its local stiffness being significantly lower than that of the surrounding region. This design enables the expansion stroke of the massage air bag 110 to be more effectively converted into effective pressing depth on the human body, reducing the dissipation of energy in the cushion material. At the same time, the existence of the weakened region 20 creates a dynamic pressure gradient. The action region of the massage air bag 110 generates concentrated stress due to the reduced stiffness, while the surrounding region maintains the original supporting characteristics. This pressure distribution pattern ensures the stimulation intensity of the massage points, and maintains the comfortable support of the non-massage region. In addition, this scheme exhibits high architectural adaptability. The concept of the weakened region 20 is independent of the specific layered structure of the cushion, and can be applied to a single material layer or a composite layer structure. Engineering practice shows that this design is compatible with a variety of existing seat structures, including polyurethane foam cushions of different thicknesses, various heating unit 220 integrated structures, and various fabric cover layers 230.

[0058] Regarding the force transmission layer, it can be set to various shapes and structures:

[0059] Method one, the force transmission layer includes a soft layer 210 and a cover layer 230. The soft layer 210 is arranged on the side of the pneumatic massage unit close to the human body; the cover layer 230 is used to cover the soft layer 210 and is in contact with the human body; at least one of the cushion and the cover layer 230 is provided with a weakened region 20.

[0060] The force transmission layer of this embodiment adopts a double-layer composite structure, which is composed of a soft layer 210 and a cover layer 230. Preferably, the soft layer 210 is made of polyurethane foam material, and the preferred thickness is 8 mm, and its surface is directly in contact with the massage air bag 110. The cover layer 230 is made of a two-way elastic knitted fabric, which is combined with the edge of the soft layer 210 through a high-frequency welding process.

[0061] The weakened region 20 includes a through structure and / or a non-through structure, specifically:

[0062] When the weakening region 20 is set as a through structure, the through structure is set as one or more of a diamond pattern 201, a wave pattern 202, a radial pattern 203, a rice pattern 204, a cross pattern 205, a circular hole 206, and a long circular hole 207. Preferably, the diamond pattern 201 is mainly arranged in the waist support area, and the long axis of a single diamond cell is 5 mm and the short axis is 3 mm, so as to adapt to the curved surface shape of the waist by virtue of the good multidirectional deformation characteristics thereof. The wave pattern 202 has a peak-to-valley distance of 4 mm, so as to realize soft support by virtue of the continuous wave characteristics thereof. The radial pattern 203 radiates outward from a massage center as a starting point, and is preferably used in the shoulder massage area, with a maximum radial radius of 15 mm, so as to conform to the physiological curve of the shoulder. The rice pattern 204 and the cross pattern 205 are preferably arranged in the main stress area of the seat cushion, so as to provide uniform support performance by virtue of the symmetrical structure thereof.

[0063] When the weakening region 20 is set as a non-through structure, the non-through structure is set as one or more of the diamond pattern 201, the wave pattern 202, the radial pattern 203, the rice pattern 204, the cross pattern 205, the circular hole 206, the long circular hole 207, and the annular groove 208. Preferably, the diamond pattern 201 has a groove depth of 0.6 mm, and is mainly arranged in the non-direct contact area, so as to provide necessary flexibility while maintaining the integrity of the surface. The wave pattern 202 has a groove depth of 0.5 mm, and is preferably arranged along the seat contour line, so as to enhance the fit of the cladding layer 230. The radial pattern 203 has a groove depth of 0.4 mm, and is preferably arranged around the main massage point, so as to play a stress guiding role. The annular groove 208 is preferably arranged in the center area corresponding to the massage air bag 110, has an inner diameter of 3 mm and an outer diameter of 4 mm, and provides a containing space for the massage protrusion.

[0064] Among them, the through structure is applied to the soft layer 210 to better reduce the weakening of the massage effect, and the cladding layer adopts the non-through structure such as the diamond pattern 201, the wave pattern 202, the radial pattern 203, the rice pattern 204, and the cross pattern 205 to avoid impurities from entering.

[0065] The through structure of this mode significantly reduces the local stiffness of the soft layer 210 by removing part of the material, so that the expansion movement of the massage air bag 110 can be more fully converted into effective pressing on the human body. The non-through structure realizes controllable reduction of stiffness while maintaining the continuity of the material by reducing the local thickness. The synergistic effect of the two makes the force transmission layer have excellent deformation ability in the massage area, and maintains sufficient support stiffness in the non-massage area, thereby realizing the best balance between massage intensity and comfort.

[0066] The second mode, the force transmission layer includes a heating unit 220 and a cladding layer 230. The heating unit 220 is arranged on the side of the pneumatic massage unit close to the human body; the cladding layer 230 is used to cover the heating unit 220 and contact the human body; at least one of the heating unit 220 and the cladding layer 230 is provided with a weakening zone 20. The heating unit 220 adopts carbon fiber heating sheet, and the preferred thickness is 1.2 mm; the cladding layer 230 selects leather material and is combined with the heating unit 220 through a special adhesive.

[0067] The weakening zone 20 includes a through structure and / or a non-through structure, in particular:

[0068] When the weakening zone 20 is arranged as a through structure, the through structure is arranged as one or more of a rhombic pattern 201, a wavy pattern 202, a radial pattern 203, a rice pattern 204, a cross pattern 205, a circular hole 206, and a long circular hole 207. Preferably, the rhombic pattern 201 is mainly arranged in the edge area of the heating unit 220, with a unit size of 4 mm x 4 mm, to avoid affecting the integrity of the main heating circuit. The wavy pattern 202 is preferably arranged along the heating wire direction, with a peak-to-valley distance of 3 mm, coordinated with the current path. The radial pattern 203 is preferably arranged with the heating center as the origin, with a maximum radial radius of 20 mm, to ensure uniform diffusion of heat. The circular hole 206 is preferably arranged in a hexagonal close-packed distribution in the non-critical heating area, with a diameter of 3 mm, to reduce stiffness while maintaining heat conduction efficiency.

[0069] When the weakening zone 20 is arranged as a non-through structure, the non-through structure is arranged as one or more of a rhombic pattern 201, a wavy pattern 202, a radial pattern 203, a rice pattern 204, a cross pattern 205, a circular hole 206, a long circular hole 207, and a ring groove 208. The surface of the heating unit 220 is provided with a corresponding groove network according to the thermal field distribution, and the groove network is composed of non-through structures, which can adopt one or more of a rhombic pattern 201, a wavy pattern 202, a radial pattern 203, a rice pattern 204, a cross pattern 205, a circular hole 206, a long circular hole 207, and a ring groove 208. Preferably, the depth of the ring groove 208 is 0.3 mm, and it is mainly arranged around the high-temperature area to play a heat isolation role. The groove depth of the wavy pattern 202 is 0.3 mm, and it is preferably arranged in the area with large temperature gradient to optimize the thermal stress distribution. The groove depth of the rhombic pattern 201 is 0.4 mm, and it is preferably used in large-area heating areas to realize uniform adjustment of stiffness. The grooves formed by all non-through structures avoid the electric heating wire to ensure electrical safety.

[0070] The through structure of the present mode ensures the reliability of electrical connection while reducing the rigidity of the heating unit 220 through careful geometric design. The non-through structure realizes the synergistic optimization of mechanical and thermal properties through precise depth control. This design allows the heating unit 220 to deform appropriately when subjected to massage pressure without affecting its heating function, while avoiding material fatigue damage caused by stress concentration. The heat transfer path and the mechanical transmission path are optimally matched through structural design, ensuring the unity of heating efficiency and massage effect.

[0071] Mode three, the force transmission layer includes a soft layer 210, a heating unit 220, and a cladding layer 230;

[0072] The soft layer 210 is arranged on the side of the pneumatic massage unit close to the human body;

The soft layer 210 adopts a slow-rebound sponge material, preferably with a density of 65 kg / m³ and a thickness of 10 mm. The heating unit 220 is a flexible graphene heating film, preferably with a thickness of 0.8 mm. The cladding layer 230 adopts a three-dimensional mesh cloth material, preferably with a thickness of 1.5 mm and a permeability of 1200 L / m² / s. The three-layer structure is laminated and compounded by an environmentally friendly polyurethane adhesive.

[0077] The weakening area 20 includes a through structure and / or a non-through structure, specifically:

[0078] When the weakening area 20 is set as a through structure, the through structure is set as one or more of diamond pattern 201, wave pattern 202, radial pattern 203, rice pattern 204, cross pattern 205, round hole 206, and long round hole 207. The cross-shaped pattern is mainly arranged in the high-pressure area with an arm length of 6 mm, providing stable support due to its orthogonal characteristics. The radial pattern 203 is preferably used in the stress dispersion area with a maximum radial radius of 25 mm, guiding the natural dispersion of stress. The rice pattern 204 is preferably arranged in areas requiring multidirectional flexibility, with each branch length of 7 mm. The long round hole 207 is preferably arranged along the main stress direction with a long axis of 10 mm, suitable for linear massage areas.

[0079] When the weakening region 20 is set as a non-penetrating structure, the non-penetrating structure is set as one or more of a checkered pattern 201, a wavy pattern 202, a radial pattern 203, a herringbone pattern 204, a cross pattern 205, a circular hole 206, an oblong hole 207, and an annular groove 208.

The cladding layer 230 adopts a composite weakening structure, and preferably, the micro-holes are mainly arranged in the direct contact region to provide good air permeability; the grid grooves are preferably arranged in the non-contact region and have a depth of 0.2 mm to maintain the overall structural stability.

[0080] The weakening structures of the respective layers cooperate with each other in space, the penetrating structure of the soft layer 210 mainly undertakes deformation function, the non-penetrating structure of the heating unit 220 is responsible for stress distribution optimization, and the composite structure of the cladding layer 230 realizes fine adjustment of surface characteristics. This multi-layer coordinated design ensures the effective transmission of massage effect and the realization of comfortable experience.

[0081] It should be noted that the force transmission layer includes the soft layer 210, the heating unit 220, and the cladding layer 230, and also includes pressure pads, thermal insulation layers, reflective layers, and the like, which can be selected as needed. Among them, the pressure pad is used to uniformly disperse the body weight pressure of the driver and passenger, reduce the compression feeling of the stress concentration areas such as the buttocks and back, and relieve fatigue after a long time of driving. The pressure pad can be made of high-density memory foam; the thermal insulation layer is used to block the conduction and penetration of heat, which can prevent the heat generated by exposure to the sun from entering the seat interior and also avoid heat loss of the heating unit 220 due to the heat of the temperature adjustment components inside the seat.
