Detailed Implementation

[0062] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0063] According to the first aspect of this application, referring to Figures 1 to 7 This disclosure provides a seat cushion for use in a seat structure. Exemplarily, it is applicable to an automotive seat, which includes a seat cushion and a seat back. The seat cushion is disposed at the lower part of the seat structure to provide support for the buttocks of the occupant, while the seat back is disposed above it to provide support for the occupant's back. Through the coordinated arrangement of the seat cushion and seat back, overall stable support can be provided for the occupant during vehicle operation, which helps maintain a good riding posture and experience under different driving conditions. This, to a certain extent, helps to mitigate the transmission of impacts during driving, improving riding comfort and stability.

[0064] It should be noted that the term "stable support" used in this manual should be understood as the ability of the seat cushion and seat back to adapt to the inertial forces exerted on the body of the passenger under different driving conditions during vehicle operation, thereby maintaining or guiding the seating posture to a certain extent. It does not mean that there is no deformation or shape change at all, but rather that the support function is achieved within a reasonable deformation range.

[0065] In some embodiments, refer to Figure 1 , Figure 2The seat cushion includes a base plate 100 and multiple seat cushion modules 200. The multiple seat cushion modules 200 are mounted on the base plate 100; that is, the base plate 100 serves as a load-bearing structure, providing a mounting base for the multiple seat cushion modules 200, thus forming a structurally integrated support relationship between the base plate 100 and the seat cushion modules 200. This modular assembly structure facilitates targeted configuration of the seat cushion modules 200 according to different functional areas, adapting to the support needs of different seating areas, and also contributes to modular design and subsequent maintenance.

[0066] Specifically, the substrate 100 and the cushion module 200 can be fixedly connected, for example, by welding, gluing, or screw fastening for unintended disassembly, to achieve structural integration. Taking welding as an example, a pre-set positioning point can be provided on the surface of the substrate 100, and the bottom of the cushion module 200 can be positioned accordingly. Welding achieves partial fusion, forming a stable bond at the connection point, which improves connection strength and is suitable for withstanding dynamic loads during long-term use. Alternatively, when using screw fastening, threaded holes can be provided on the substrate 100, and through holes 121 can be provided on the corresponding part of the cushion module 200. Screws are inserted and tightened, forming a reliable fixed relationship. This method facilitates mass assembly and offers high connection stability.

[0067] In other embodiments, the base plate 100 and the seat cushion module 200 can also be detachably connected. This connection method facilitates the replacement of damaged or worn seat cushion modules 200 and also helps to customize the seat comfort according to specific usage needs. Detachable connection methods can include snap-fit ​​connections, bolt connections, etc. Among them, the snap-fit ​​structure, which enables quick assembly and disassembly, has high convenience.

[0068] Specifically, the base plate 100 has a slot structure, and the seat cushion module 200 has a protrusion structure that mates with the slot. The protrusion structure has a certain degree of elasticity or taper. When the seat cushion module 200 is pressed downwards for installation, the protrusion structure can deform to a certain extent and enter the slot, forming a limiting fit at the edge of the slot. This structure allows for the installation and removal of the module without tools, improving installation efficiency and facilitating the replacement of partial modules during maintenance. To enhance connection reliability, the slot and the protrusion structure can be designed as a multi-point distributed structure, thereby providing shear resistance in multiple directions at the connection points and ensuring the stability of the seat cushion module 200 during use.

[0069] For example, when using bolted connections, pre-embedded nuts or limiting holes can be provided on the base plate 100, and corresponding through holes 121 can be provided at the bottom of the seat module 200. After the bolts are inserted and connected, a strong tension effect can be formed, which is suitable for use in scenarios requiring greater installation strength or high load. Bolted connections facilitate repeated disassembly and assembly, and also have high structural reliability.

[0070] In some embodiments, refer to Figure 1 , Figure 2 Multiple seat cushion modules 200 are combined to form hip support. By distributing seat cushion modules 200 with different functional positions, more targeted support can be provided to the buttocks and their surrounding areas, which helps to alleviate the local pressure caused by long-term sitting to a certain extent.

[0071] In one embodiment, reference is made to... Figure 2 , Figure 4 The seat cushion module 200 comprises five modules. The first module is located in the center of the seat cushion, providing direct support to the main pressure-bearing area of ​​the buttocks. The second and third modules are located on the left and right sides of the central module, respectively, conforming to the contours of the buttocks and providing lateral support, which helps improve lateral stability during riding. The fourth module is located at the front of the central module, designed to fit the natural curvature of the occupant's legs, thereby reducing the contact pressure on the front edge of the legs to some extent. The fifth module is located at the rear of the central module, corresponding to the area where the occupant's coccyx is located. Its independent arrangement helps to disperse the contact stress in the coccyx area, improving riding comfort.

[0072] In another embodiment, refer to Figure 3 As shown, there are four seat cushion modules 200. The first seat cushion module 200 is located in the middle and is used to support the main pressure area of ​​the buttocks. The second and third seat cushion modules 200 are located on the left and right sides of the middle seat cushion module 200, respectively, to conform to the contours of the buttocks and provide lateral support, thus playing a certain role in stability. The fourth seat cushion module 200 is located at the front of the middle seat cushion module 200 and is used to conform to the natural bending part of the legs, thereby providing local support and playing a certain role in cushioning to improve the riding experience.

[0073] In another embodiment, refer to Figure 4As shown, there are three seat cushion modules 200. The first seat cushion module 200 is located in the middle and provides the main support for the core pressure area of ​​the buttocks. The second seat cushion module 200 is located at the front of the middle seat cushion module 200 and is used to cooperate with the naturally bent part of the legs to provide a certain degree of support and cushioning. The third seat cushion module 200 is located at the rear of the middle seat cushion module 200 and is arranged corresponding to the coccyx area to provide support and reduce the pressure intensity on the coccyx to a certain extent.

[0074] It is understood that the specific number of seat cushion modules 200 can be flexibly configured according to different usage needs and application scenarios. This application does not limit the number of seat cushion modules 200 to a specific value, but covers design schemes with various quantity configurations. In different embodiments, three, four, five, or more seat cushion modules 200 can be selected according to the required support distribution accuracy, seat type, or ergonomic requirements, thereby adapting to the body characteristics and comfort needs of different users.

[0075] For example, increasing the number of seat cushion modules 200 facilitates a more detailed regional support arrangement to adapt to the pressure distribution characteristics of different areas. In applications with limited space or cost constraints, a smaller number of seat cushion modules 200 can be combined to achieve structural simplicity and ease of module replacement. Therefore, the number of seat cushion modules 200 is not a necessary limitation of the technical solution of this application, but can be selected and adjusted according to actual design requirements.

[0076] This application is intended to protect all configuration schemes including but not limited to the specific number of cushion modules 200 mentioned above. Any design that uses multiple cushion modules 200 to form a support structure to achieve a regional support effect should be considered to fall within the protection scope of this application.

[0077] In some embodiments, the substrate 100 is at least partially elastic, and at least one seat cushion module 200 adjusts its posture according to the elastic deformation of the substrate 100. It is understood that at least one seat cushion module 200 is arranged corresponding to the elastic region of the substrate 100, enabling the seat cushion module 200 to adjust its posture according to the elastic deformation of the substrate 100. Specifically, because the substrate 100 has an elastic region, when a passenger sits down, the seat cushion module 200 is subjected to a force from the buttocks. This force is transmitted through the seat cushion module 200 to the corresponding elastic region 120 of the substrate 100, causing local elastic deformation of the substrate 100. During this process, the seat cushion module 200 arranged in this region also undergoes corresponding displacement or posture adjustment, thereby making the seat cushion module 200 more conform to the actual shape of the buttocks to a certain extent.

[0078] This structural design offers several technical advantages. Firstly, the elastic region 120 of the substrate 100 acts as a buffer against passenger loads. When vibrations or impacts occur during vehicle operation, this elastic region 120 absorbs some energy, thereby reducing the direct transmission of vibration to the passenger's buttocks and improving ride comfort. Secondly, the seat cushion module 200 adapts to the different buttock curves of various passengers during its elastic response, creating a smoother contact surface and achieving more targeted support distribution. This helps reduce pressure concentration in localized areas of the buttocks, enhancing support and body stability.

[0079] It should be noted that the structure of the substrate 100 can be made of an elastic material, or a flexible region of a specific shape can be formed in the rigid substrate 100 (e.g., by setting cutouts, through holes 121, or corrugated structures) to achieve the desired elastic response capability. This application does not limit the specific implementation of the elastic structure.

[0080] It is understandable that, among other things, reference Figure 8 , Figure 9 and Figure 10 The substrate 100 is at least partially elastic; that is, the substrate 100 may be entirely elastic or only partially elastic. It should be noted that "the substrate 100 is elastic" in this application means that the substrate 100 can undergo elastic deformation, i.e., the substrate 100 can deform after a certain force is applied, and can return to its original shape after the applied force is removed. Furthermore, the elasticity mentioned here refers to elasticity that meets the cushioning requirements of a seat cushion, and not merely minor elasticity.

[0081] For example, refer to Figure 9 , Figure 10 Multiple elastic regions 120 can be formed on the substrate 100, or only one elastic region 120 can be formed. Specifically, the multiple elastic regions 120 can be distributed at different positions on the substrate 100, such as the positions corresponding to the buttock pressure area, the tailbone area, or the leg support area, so that the multiple seat cushion modules 200 can achieve independent posture adjustment on their respective corresponding elastic regions 120, thereby providing differentiated elastic responses for different support positions during riding, which helps to improve the overall seat cushion's fit and cushioning performance.

[0082] In another example, only one elastic region 120 is formed on the substrate 100 (see reference). Figure 7 , Figure 8The elastic region 120 can be located in the middle region of the base plate 100 to cooperate with the seat cushion module 200 located in the middle. When the middle seat cushion module 200 bears the force from the main support area of ​​the buttocks, the elastic region 120 can deform to a certain extent, thereby causing the middle seat cushion module 200 to change its posture to adapt to different shapes and pressure distributions of the buttocks, thus achieving a more compliant and dynamic support process.

[0083] It should be noted that the elastic region 120 can be formed by means of local thinning, providing through holes 121, introducing a corrugated structure, embedding an elastic element or a flexible connection structure on the substrate 100. This application does not limit the specific implementation of the elastic region 120.

[0084] In some embodiments, multiple seat cushion modules 200 are detachably mounted on the base plate 100. This detachable connection allows the seat cushion modules 200 to be removed from the base plate 100 without affecting the overall structural stability, thus providing replaceability and expandability. On the one hand, when a seat cushion module 200 experiences aging, damage, or functional decline, maintenance can be performed by replacing the corresponding module, facilitating later use and management. On the other hand, it also allows for customized configuration of the seat cushion modules 200 according to different usage needs or passenger preferences, thereby improving adaptability and comfort.

[0085] Specifically, the structure or parameters of the seat cushion module 200 can be customized according to the shape, body characteristics, or pressure distribution of the user's buttocks to achieve a more fitting human body support state. By installing the customized module in a preset position, it is beneficial to improve the overall seat cushion's fit to the occupant's body curves, thereby enhancing the support effect and riding comfort to a certain extent.

[0086] In addition, depending on aesthetics or user preferences, the seat module 200 can also be designed differently in terms of color, shape, surface texture or firmness. Passengers can flexibly replace it according to usage scenarios (such as long-distance driving, short-distance commuting, sports mode, etc.) or personal habits, thereby achieving a certain degree of functional expansion and style customization.

[0087] It should be noted that the detachable nature of the aforementioned seat cushion module 200 can be achieved through snap-fit, bolt connection, magnetic components, guide rail sliding structure, etc. This application does not limit the specific connection mechanism, and multiple different structures can achieve the detachable installation function of the seat cushion module 200 within the protection scope of this application.

[0088] In some embodiments, at least a portion of the substrate 100 can deform away from the seat cushion, so that at least one seat cushion module 200 adjusts its posture according to the deformation of the substrate 100. Specifically, under external load, this portion of the substrate 100 undergoes downward elastic deformation relative to the overall structure of the seat cushion in the vertical direction. When a passenger sits on the seat cushion, the buttocks area presses against the seat cushion module 200, and this pressure is transmitted through the seat cushion module 200 to the elastic region 120 of the mounting base substrate 100, causing the substrate 100 to undergo downward elastic deformation.

[0089] Since the seat cushion module 200 is connected to or assembled on the substrate 100, the seat cushion module 200 located in the elastic region 120 also changes its spatial posture as the substrate 100 deforms. Through this structural design, the seat cushion module 200 can adapt to the local shape characteristics of the occupant's buttocks to a certain extent, thereby improving fit and support.

[0090] Through the above structural design, the seat cushion module 200 can adapt to changes in the local contour of the buttocks to a certain extent according to the occupant's body shape, weight, or dynamic center of gravity distribution, thereby providing more effective localized support. At the same time, the local deformation of the base plate 100 also helps to achieve a certain degree of buffering and energy absorption. When the occupant sits down or the vehicle vibrates during travel, the deformation process can disperse and absorb some of the impact force, reducing the stress directly acting on the occupant's body.

[0091] In some embodiments, refer to Figure 8 , Figure 9 and Figure 10 The substrate 100 includes an elastic region 120. Figure 8 , Figure 9 , Figure 10 The portion within the dashed box) and rigid region 110 ( Figure 8 , Figure 9 , Figure 10 (The portion outside the dashed frame) has a lower elastic modulus in the elastic region 120 than in the rigid region 110. By partitioning the substrate 100, while meeting the overall support strength requirements, local areas of the substrate 100 can be made to have good elastic deformation capabilities, which is beneficial to improving the overall performance of the seat cushion.

[0092] Specifically, the rigid region 110 provides stable support for the overall structure, maintaining the basic stability of the relative position of the seat cushion module 200 and preventing excessive deformation of the overall structure. The elastic region 120, on the other hand, enables localized controllable elastic deformation, allowing the seat cushion module 200 installed in this region to adjust its posture to some extent according to the user's hip pressure, thereby better conforming to the hip curve and improving local support.

[0093] For example, the elastic region 120 can be formed by using a material with a low elastic modulus, or by achieving a low local stiffness through structural design, such as by providing deformation grooves, corrugated structures, or hole arrays, so that it has good deformability under external force. The rigid region 110 can be made of a material with high strength and a high elastic modulus, or its structural rigidity can be enhanced by reinforcing ribs, increased thickness, etc.

[0094] Through the above-mentioned structural design that combines rigidity and flexibility, on the one hand, the overall structure can maintain high strength and deformation control capabilities, and on the other hand, it can achieve more flexible response capabilities in local areas, thereby improving the support adaptability and cushioning comfort during riding.

[0095] It should be noted that the specific distribution, shape, and quantity of the elastic region 120 and the rigid region 110 can be flexibly set according to design needs, and this application is not limited to a specific division method. The setting of the elastic region 120 can be achieved through material selection (such as elastic material, composite soft elastic structure), geometric design (such as slotting, corrugated structure, thinning area) or structural partitioning (such as setting multiple functional module areas). This application does not limit the specific implementation method of the deformation structure of the substrate 100. Different deformation structure methods can achieve the purpose of adjusting the posture of the cushion module 200 with the deformation of the substrate 100.

[0096] In some embodiments, refer to Figure 8 , Figure 9 The rigid region 110 is arranged along the edge of the substrate 100. By setting the rigid region 110 at the edge of the substrate 100, it is beneficial to improve the edge support capacity of the entire substrate 100 and enhance its overall structural stability, thereby providing a certain degree of boundary constraint and positioning effect on the seat cushion during use.

[0097] Specifically, since the edge portion of the substrate 100 plays the role of boundary sealing in the structure, if it is set as a rigid area 110, it can effectively limit the deformation range of the edge of the substrate 100, prevent the corners from warping or deforming excessively during use, and help maintain the shape integrity of the entire cushion structure and the installation stability of the cushion module 200.

[0098] Furthermore, the edge rigid region 110 also helps to support the weight and external forces borne by the entire substrate 100 to a certain extent, thereby improving the durability and load-bearing capacity of the substrate 100. For example, the rigid region 110 can be made of high-strength materials (such as high-modulus plastics, metal sheets, etc.), or it can be formed by adding reinforcing ribs or thickening the edge portion at the edge of the substrate 100 to improve the local rigidity of the edge region.

[0099] This structural design also facilitates the setting of an elastic region 120 in the middle of the substrate 100, giving the middle region better deformation capabilities to adapt to the shape changes of the occupant's buttocks, thereby achieving a synergistic combination of flexible support and stable support, and improving the overall comfort and functionality of the seat cushion.

[0100] It should be noted that the specific arrangement of the rigid area 110 is not limited to a continuous closed edge structure. It can also be a discontinuous distribution of rigid segments, or be arranged symmetrically or asymmetrically at the periphery of the substrate 100, in order to meet the actual needs of different types of seat cushion designs.

[0101] In some embodiments, refer to Figure 7 , Figure 8 The rigid region 110 surrounds the elastic region 120. Specifically, the elastic region 120 is provided in the middle of the substrate 100 to undergo elastic deformation under the action of riding load, so that the seat cushion module 200 installed in this region can adjust its posture with the deformation to better fit the contour of the occupant's buttocks; while the rigid region 110 is arranged around the elastic region 120 to form a structural surrounding support.

[0102] By setting the rigid region 110 as an enclosing structure, on the one hand, it can provide structural constraints on the elastic region 120 to a certain extent, making its elastic deformation more controllable and avoiding the impact on the overall support stability of the seat cushion due to excessive deformation; on the other hand, the rigid region 110 plays the role of transmitting and distributing external forces during the stress process, which helps to evenly transfer concentrated loads to the entire substrate 100, reduce the local stress intensity of the elastic region 120, and extend its service life.

[0103] Furthermore, this enclosed arrangement also helps to divide the substrate 100 into different functional areas, achieving a synergistic effect between rigid support and flexible buffering. For example, in vehicle seats or long-term seating scenarios, the central elastic area 120 provides dynamic support, improving fit and comfort; at the same time, the outer rigid area 110 maintains the structural shape and installation stability, helping to improve the overall support performance and safety performance.

[0104] It should be noted that the rigid region 110 can be a complete ring structure or a multi-segment rigid structure with intervals, depending on the structural form of the substrate 100 and the layout of the cushion module 200; the shape of the elastic region 120 is not limited to circles, ellipses or rectangles, etc., and can be set as polygons or irregular regions as needed to achieve greater adaptability and diversity.

[0105] In some embodiments, refer to Figure 6 , Figure 7The elastic region 120 has multiple through holes 121 penetrating the substrate 100 to enhance its deformation capability. By providing through holes 121 in the elastic region 120, the local rigidity of the region can be weakened to a certain extent, making it easier to undergo elastic deformation under stress. Specifically, these through holes 121 extend through the thickness direction of the substrate 100 and are distributed at different positions in the elastic region 120, which can effectively reduce the overall bending stiffness of the elastic region 120, enabling it to generate greater deflection under external force, thereby allowing the seat cushion module 200 installed in this region to obtain a more significant posture adjustment capability.

[0106] The above structural design improves the adaptability of the elastic area 120, allowing the seat cushion module 200 to deform according to the different contours of the buttocks during seating, thereby improving fit and comfort to a certain extent. On the other hand, the through hole 121 can also reduce material usage and lighten the overall weight of the substrate 100, which is beneficial to the lightweight design requirements of the seat system.

[0107] It should be noted that the shape, number, and distribution of the through holes 121 can be designed according to actual usage requirements. For example, the through holes 121 can be circular, elliptical, or strip-shaped; their distribution can be a regular array or an asymmetrical distribution to adapt to deformation requirements in a specific direction. In addition, in some embodiments, the edges of the through holes 121 can be provided with flexible rounded corners or reinforcing edges to improve their structural stability during long-term repeated deformation.

[0108] In some embodiments, at least one seat cushion module 200 is connected to the elastic region 120. Specifically, the seat cushion module 200 is disposed on the elastic region 120 by a fixed connection or a detachable connection, so that the seat cushion module 200 can change posture with the local deformation of the elastic region 120 when pressure is applied to the buttocks of the occupant. This structural configuration is beneficial for effectively transmitting external loads to the elastic region 120, causing the substrate 100 to elastically flex in the vertical or local direction, thereby adapting to the contour characteristics of the occupant's buttocks and providing a certain degree of cushioning effect.

[0109] This connection method allows the cushion module 200 located in the elastic region 120 to automatically adapt its posture through the structural response characteristics of the base plate 100 itself, without adding a complex transmission mechanism. Compared to the rigid region 110, the elastic region 120 can undergo controllable deformation after being subjected to force, thereby enabling the cushion module 200 connected thereto to achieve a certain range of angle adjustment or position fine adjustment, so as to improve the fit between the cushion module 200 and the human body contact area.

[0110] It should be noted that the number of seat cushion modules 200 connected to the elastic area 120 can be one or more, and their specific arrangement can be optimized according to the anatomical structure of the human body or the pressure distribution requirements. For example, seat cushion modules 200 corresponding to the main pressure area of ​​the buttocks or the tailbone area can be set in the elastic area 120 to improve local cushioning and support performance.

[0111] In some embodiments, refer to Figure 5 , Figure 6 At least one seat cushion module 200 is connected to the rigid region 110. Since the rigid region 110 has higher structural strength and a larger elastic modulus than the elastic region 120, the seat cushion module 200 located in this region has a more stable installation position under riding loads and can play a stronger supporting and limiting role.

[0112] Specifically, the rigid region 110 is suitable for use as an edge positioning support. For example, a seat cushion module 200 located at the edge of the seat cushion is connected to the rigid region 110 to limit the lateral or longitudinal range of movement of the occupant's buttocks. This structural design helps to constrain the position of the buttocks, preventing them from sliding or swaying excessively on the seat cushion surface during vehicle movement or vibrations, thereby improving riding stability and safety.

[0113] Furthermore, connecting the seat cushion module 200 to the rigid region 110 helps to form a relatively fixed support boundary, complementing the seat cushion module 200 located in the elastic region 120. That is, the rigid region 110 provides boundary support and stability, while the elastic region 120 provides adaptation and cushioning, thereby improving the overall support performance and comfort of the seat cushion for the buttocks.

[0114] It should be noted that the number and specific distribution of the seat cushion modules 200 connected to the rigid area 110 can be flexibly configured according to the actual usage scenario. For example, multiple seat cushion modules 200 can be set on the left and right sides, rear end or front edge to form a wraparound support structure to further stabilize the sitting posture of the passenger.

[0115] In some embodiments, refer to Figure 3 , Figure 4 The seat cushion also includes a seat cushion frame 300, to which the base plate 100 is fixed, thus forming a stable support structure. The seat cushion frame 300, as the structural foundation of the seat cushion, is usually made of metal or high-strength composite materials, and has high rigidity and overall load-bearing capacity, serving as a bottom support frame for the base plate 100 and multiple seat cushion modules 200.

[0116] By fixing the substrate 100 to the seat cushion frame 300, the structural stability of the substrate 100 during use is ensured, preventing undesirable displacement or deformation under repeated pressure or vibration, thereby ensuring the consistency of the installation position and function of the multiple seat cushion modules 200. The fixing method can include structural connection methods such as screw connection, snap-fit, riveting or bonding, and the specific selection can be adjusted according to the material characteristics and manufacturing process.

[0117] Furthermore, the fixing relationship between the substrate 100 and the seat cushion frame 300 also helps to rationally divide the structural functional areas. For example, in some embodiments, a certain distance is reserved between the elastic area 120 and the seat cushion frame 300 or a flexible connection part is provided, thereby giving the elastic area 120 sufficient deformation space; while the rigid area 110 can be directly fastened to the seat cushion frame 300 to enhance its load-bearing capacity. Through the above structural cooperation, the synergistic effect of flexibility and rigidity in the overall seat cushion structure can be achieved, which to a certain extent helps to improve support stability and riding comfort.

[0118] It should be noted that the structural form, material type, and connection method between the seat frame 300 and the substrate 100 do not constitute a limitation on this application and can be adapted according to specific application scenarios and process requirements.

[0119] In some embodiments, at least a portion of the rigid region 110 of the substrate 100 is connected to the seat cushion frame 300. Since the rigid region 110 has high structural strength and resistance to deformation, connecting it to the seat cushion frame 300 helps to form a stable support base in the structure, thereby improving the mechanical properties of the entire seat cushion.

[0120] Specifically, the rigid region 110 can be connected to the seat cushion frame 300 by means of screws, clips, riveting, or bonding. The connection method can be selected according to the specific material properties and assembly process, and is not limited to a specific form. In actual use, by firmly connecting the rigid region 110 to the seat cushion frame 300, the relative displacement of this region under stress can be effectively limited, making it a stable platform supporting multiple seat cushion modules 200.

[0121] It should be noted that the connection between the rigid region 110 and the seat frame 300 can be an integral connection or a distributed connection, that is, multiple rigid regions 110 are respectively disposed at different positions on the base plate 100 and partially connected to the frame to adapt to different structural design schemes. Therefore, this application does not limit the connection position and connection method, and all equivalent structures based on this concept should fall within the protection scope of this application.

[0122] In some embodiments, refer to Figure 2 , Figure 5The multiple seat cushion modules 200 include a first side wing support pad 210 and a second side wing support pad 220. The first side wing support pad 210 is mounted on one side of the base plate 100 along a first axis, and the second side wing support pad 220 is mounted on the other side of the base plate 100 along the first axis. The first axis can be understood as a reference axis extending along the front-back direction of the occupant's body. Figure 2 and Figure 3 The dotted line in the diagram represents the first axis, which is usually aligned with the longitudinal centerline of the seat cushion. Based on this arrangement, the first side wing support pad 210 and the second side wing support pad 220 correspond to the left and right sides of the occupant's buttocks, respectively, enabling adaptation and support for the lateral contour of the buttocks.

[0123] Specifically, the first side wing support pad 210 and the second side wing support pad 220 can be fixedly or detachably installed on the base plate 100, and their connection points can be located in the elastic region 120, the rigid region 110, or a transition region between the two, to meet the support needs of different parts. By setting these two side support pads, the lateral movement of the buttocks can be restricted to a certain extent, which helps to improve stability and comfort during riding.

[0124] Furthermore, the shape, firmness, and size of the side support pads can be designed and optimized according to different usage needs. For example, by adopting a gradient soft material structure or a composite support layer structure, a more ergonomic support effect can be provided. In addition, the side support pads can also be equipped with an adjustment mechanism to achieve adaptive adjustment for users of different body types, further improving riding comfort and personalized adaptability.

[0125] It should be noted that the setting of the first axis does not constitute a limitation on the technical solution of this application. It can be a reference axis defined as needed in the actual seat structure, and all left and right arrangement schemes based on this axis should fall within the protection scope of this application.

[0126] In some embodiments, refer to Figure 5 , Figure 6 The substrate 100 includes a first side plate 130 and a second side plate 140. A first side wing support pad 210 is mounted on the first side plate 130, and a second side wing support pad 220 is mounted on the second side plate 140. The first side plate 130 and the second side plate 140 are inclined towards the center of the substrate 100 to provide support and wrap around the buttocks of the occupant. Specifically, the side of the first side plate 130 and the second side plate 140 away from the center of the substrate 100 is inclined towards the upper part of the seat cushion at a certain angle, so that the first side wing support pad 210 and the second side wing support pad 220 are in an inward wrapping posture.

[0127] Specifically, the first side plate 130 and the second side plate 140 can be integrally formed on the base plate 100 body, or fixed to both sides of the base plate 100 by mechanical connection; the tilt angle of the side plates can be optimized according to the contour structure of the human buttocks, usually set to an inward tilt angle of 5° to 45°, to enhance the fit and coverage of the outer side of the buttocks. Through the above structural design, during the riding process, the sides of the buttocks of the passenger can form flexible contact with the side wing support pads, thereby limiting the lateral swaying of the buttocks, improving the stability of the sitting posture and enhancing the riding comfort to a certain extent.

[0128] Furthermore, the side panel body can be made of rigid material to form a stable support structure, or elastic buffer layers or elastic connection structures can be set in local areas to absorb external impacts while maintaining the covering shape and improving the overall shock absorption performance. Correspondingly, the side wing support pads installed on the side panel can also be designed with angle matching according to the side panel tilt angle to ensure that they form an effective support surface facing the center of the base plate 100 after installation.

[0129] It should be noted that the specific structure, material and tilt angle of the first side plate 130 and the second side plate 140 can be flexibly adjusted according to the usage requirements, and do not constitute a limitation on the scope of protection of this application. All side support structures formed based on the principle of central covering support should be regarded as technical solutions of this application.

[0130] In some embodiments, refer to Figure 1 , Figure 2 The multiple seat cushion modules 200 also include a first end support pad 230. The first end support pad 230 is mounted on a first end of the base plate 100 along a first axis. Exemplarily, the first end support pad 230 is disposed at the front end of the seat cushion.

[0131] The first end support pad 230 can conform to the natural bending part of the occupant's legs, providing appropriate support and cushioning to reduce local pressure in the front area of ​​the legs, thereby improving riding comfort to a certain extent. In addition, the size, shape and material of the first end support pad 230 can be adjusted according to specific application needs to adapt to different body types and usage scenarios.

[0132] The first end support pad 230 can be fixedly or detachably connected to the base plate 100 to facilitate maintenance, replacement, or customization according to user needs. The first end support pad 230 can form a more complete support system in the overall seat cushion module 200 assembly, working synergistically for the buttocks and legs, which helps to improve the applicability and functional versatility of the seat cushion.

[0133] In some embodiments, refer to Figure 1 , Figure 2The first end support pad 230 includes a first segment 231 and a second segment 232 that are inclined to each other. The first segment 231 is located on the surface of the substrate 100, and the second segment 232 extends to the first end of the substrate 100 to cover the first end of the substrate 100. This structural design is beneficial for achieving a smooth curve transition from the hip area to the leg area, which is suitable for the natural shape of the occupant's legs and helps to improve the continuity and comfort of the support.

[0134] The first segment 231 and the second segment 232 can adopt a one-piece molded structural design to reduce the structural complexity and potential fatigue points at the connection points, thereby improving the overall structural stability and durability. Alternatively, the first segment 231 and the second segment 232 can be set separately, achieving a relatively independent structural layout through connectors or flexible interfaces, facilitating modular design and easy replacement. Preferably, an integrated design is used to achieve a consistent and coordinated support effect.

[0135] This covering structure can limit excessive deformation at the first end of the substrate 100 to a certain extent, while also helping to stabilize the leg position of the passenger, reduce local stress concentration, and improve the overall support performance and riding comfort of the seat cushion.

[0136] In some embodiments, refer to Figure 5 The substrate 100 is provided with a mounting groove, and the first end support pad 230 is provided with a structure that mates with the mounting groove, so as to facilitate the mounting of the first end support pad 230 onto the substrate 100. By cooperating with the mounting groove and the mating structure, the mounting position of the first end support pad 230 can be defined, thereby improving its fixed stability on the substrate 100 and preventing installation misalignment or loosening.

[0137] The mounting slot simplifies the installation process of the first end support pad 230, enabling it to be accurately and quickly positioned and fixed in the predetermined location, thus improving production and assembly efficiency. Simultaneously, this structural design can also, to a certain extent, withstand and disperse the force from the first end support pad 230, reducing the risk of loosening due to localized stress.

[0138] The specific shape, size, and materials of the mounting groove and mating structure can be designed and adjusted according to actual needs to adapt to different application environments and installation requirements. Other equivalent structural design schemes are also included within the scope of protection of this application.

[0139] In some embodiments, refer to Figure 1 , Figure 2 The multiple seat cushion modules 200 also include a second end support pad 240. The second end support pad 240 is mounted on the second end of the base plate 100 along the first axis. Exemplarily, the second end support pad 240 is disposed at the rear end of the seat cushion to provide support and protection for the coccyx region of the occupant.

[0140] The structure and material of the second end support pad 240 can be selected from elastomers, foam materials, or other materials with cushioning properties as needed to alleviate pressure concentration in the coccyx area to a certain extent and improve riding comfort. By setting the second end support pad 240, the force on the coccyx area can be effectively distributed, reducing the discomfort caused by pressure on the coccyx during long-term sitting, which is conducive to improving the overall ergonomic performance and user experience of the seat cushion.

[0141] In some embodiments, refer to Figure 1 , Figure 2 The multiple seat cushion modules 200 also include a main support pad 250. The main support pad 250 is mounted in the central region of the base plate 100. The main support pad 250 is used to provide direct support to the main pressure-bearing areas of the buttocks, thereby helping to distribute the pressure in this area and improve riding comfort and support.

[0142] The main support pad 250 can be constructed using materials with a certain degree of elasticity, such as foam, elastomer, or multi-layer composite structures, to cushion the pressure on the occupant and adapt to the shape of the buttocks. The main support pad 250 works in conjunction with other seat cushion modules 200, and through a reasonable distribution layout, it helps to provide stable support to the core area of ​​the buttocks. Simultaneously, in conjunction with the elastic deformation of the base plate 100, it can better adapt to the differences in body shape among different occupants, improving overall support performance and comfort.

[0143] In some embodiments, refer to Figure 1 , Figure 2 The first side wing support pad 210 of the seat cushion module 200 is located on one side of the main support pad 250, and the second side wing support pad 220 of the seat cushion module 200 is located on the other side of the main support pad 250. Both are distributed along the width direction of the main support pad 250, thereby providing effective lateral support to both sides of the buttocks. This arrangement helps improve the stability of the buttocks, reduces lateral slippage during seating, and enhances the sense of security and comfort while riding.

[0144] In some embodiments, the first end support pad 230 of the seat cushion module 200 is located at the first end of the main support pad 250. It typically corresponds to the position where the occupant's legs are naturally bent, thereby providing appropriate support and cushioning to that area and improving the riding experience.

[0145] In some embodiments, the second end support pad 240 of the seat cushion module 200 is located at the second end of the main support pad 250, typically corresponding to the rear end of the seat, and located at the coccyx area. The second end support pad 240 helps to provide support and protection to the coccyx region, alleviates stress concentration in this area, and improves safety and comfort during riding.

[0146] In some embodiments, refer to Figure 2 , Figure 5 The first side wing support pad 210 and the second side wing support pad 220 of the seat cushion module 200 are mounted on the rigid area 110 of the base plate 100. This provides better restraint and lateral support through the rigid area 110, thereby stabilizing the hip position and preventing large-scale lateral displacement of the occupant.

[0147] In some embodiments, the first end support pad 230 of the seat cushion module 200 is mounted on the rigid region 110 of the base plate 100. The structural characteristics of the rigid region 110 provide stable support for the bent leg area, promoting riding comfort and stability.

[0148] In some embodiments, the second end support pad 240 of the seat cushion module 200 is mounted on the rigid region 110 of the base plate 100. The supporting effect of the rigid region 110 helps to provide effective protection and restraint to the coccyx, reducing the stress concentration on the coccyx.

[0149] In some embodiments, the main support pad 250 of the seat cushion module 200 is mounted on the elastic region 120 of the base plate 100. The presence of the elastic region 120 is beneficial for cushioning sitting pressure and can adjust to a certain extent according to the changes in the shape of the occupant's buttocks, thereby improving the adaptability and comfort of the support.

[0150] By rationally distributing and coordinating the rigid region 110 and the elastic region 120, the seat cushion module 200 can achieve a balance between support stability and cushioning adaptability, thereby better meeting the needs of passengers.

[0151] In some embodiments, refer to Figure 5 , Figure 6 The seat cushion also includes a cooling device 400 for ventilating and / or cooling at least one seat cushion module 200. The cooling device 400 promotes airflow, which is beneficial for improving comfort during seating by helping to reduce the temperature and humidity of the seat cushion surface, thereby alleviating discomfort that may be caused by prolonged seating. Exemplarily, the cooling device 400 may include a fan, an air conditioning system, or other devices suitable for cooling the seat cushion module 200.

[0152] In some embodiments, refer to Figure 3 , Figure 5 At least one seat cushion module 200 is provided with a ventilation hole 251, and a cooling device 400 is used to ventilate the ventilation hole 251. The ventilation hole 251 is used to promote air circulation, thereby improving riding comfort and heat dissipation.

[0153] In some embodiments, the main support pad 250 of the seat cushion module 200 is provided with ventilation holes 251. The main support pad 250 is located in the middle position, and ventilation at this position can achieve a better cooling effect. The main support pad 250 is located in the middle position of the seat cushion, and ventilation at this position is beneficial to achieving a more effective cooling effect, further improving the comfort experience of the occupants.

[0154] In some embodiments, refer to Figure 11 The seat cushion module 200 includes a seat cushion plate 260, which is connected to the base plate 100. The seat cushion plate 260 enables an effective connection between the seat cushion module 200 and the base plate 100, thereby improving the stability of the connection. Simultaneously, the seat cushion plate 260 helps to effectively transfer the forces borne by the seat cushion module 200 to the base plate 100, which is beneficial for ensuring the coordinated operation and support effect of the overall structure.

[0155] In some embodiments, the seat cushion module 200 includes a foam body 270. The foam body 270 can provide good cushioning performance to a certain extent, which is beneficial to improving the contact feeling of the buttocks and legs, thereby enhancing the comfort of riding.

[0156] In some embodiments, refer to Figure 11 The foam body 270 is connected to the seat cushion plate 260. The combination of the foam body 270 and the seat cushion plate 260 can improve the overall stability of the seat cushion module 200 to a certain extent, while also improving the riding experience and enhancing the cushioning effect and support performance.
