Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a support pad assembly, a seat, and a vehicle. Background Technology

[0002] Vehicle seats in related technologies typically have air springs installed within a foam base layer. By inflating and deflating the air springs, the firmness of the seat cushion can be adjusted to meet the comfort and support needs of different occupants.

[0003] However, in related technologies, the foam base of the seat cushion and the air spring are usually simply stacked or embedded together, with the foam base layer only serving as the basic load-bearing layer. The two lack effective coordination during the load-bearing process, resulting in a lack of comfort and stability in load support, and a poor user experience. Summary of the Invention

[0025] In the description of this invention, "first feature" and "second feature" may include one or more of the features.

[0026] In the description of this invention, "a plurality of" means two or more, and "several" means one or more.

[0027] The support pad assembly 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0028] It should be noted that, as Figures 1-6 As shown in the attached figure, the directions in the figure are taken with reference to the direction of the support pad assembly 1. That is, the length direction in the figure is the length direction of the support pad assembly 1, the width direction is the width direction of the support pad assembly 1, and the thickness direction is the thickness direction of the support pad assembly 1.

[0029] The support pad assembly 1 according to an embodiment of the present invention includes an elastic base 100 and an inflatable member 200. The elastic base 100 is configured with a plurality of mounting cavities 110, and elastic ribs 120 are formed between at least two adjacent mounting cavities 110. The inflatable member 200 is disposed within the mounting cavity 110 and is adapted to be connected to an inflation adjustment device (not shown in the figure). The inflatable member 200 has a deflated state and an inflated state. There can be a plurality of inflatable members 200, and the plurality of inflatable members 200 are disposed one-to-one within the plurality of mounting cavities 110.

[0030] When the inflatable component 200 is in the deflated state, it retracts into the mounting cavity 110, and the elastic base 100 forms a separate support; when the inflatable component 200 is in the inflated state, it fills the mounting cavity 110 and supports the elastic base 100, so as to form a composite support with the elastic base 100.

[0031] The inflatable component 200 can be an inflatable bag, made of a flexible material with good airtightness (such as TPU, thermoplastic polyurethane elastomer). The elastic matrix 100 can be composed of flexible foam, rubber, or other high-resilience materials. The edges of the inflatable component 200 can be connected and fixed to the edges of the mounting cavity 110 to ensure a close fit between the inflatable component 200 and the mounting cavity 110. Furthermore, the elastic matrix 100 can be a single piece of foam structure, which provides a large load-bearing area, helps avoid localized stress concentration, and creates a good sense of envelopment, providing users with a softer and more comfortable riding experience.

[0032] Furthermore, it should be noted that the inflation state of the inflatable component 200 includes both the state in which the gas inside the inflatable component 200 is full and the state in which the gas inside the inflatable component 200 is not full. When the amount of gas filled into the inflatable component 200 reaches a certain amount, the inflatable component 200 can have a certain supporting capacity, and thus can work together with the elastic matrix 100 to provide support.

[0033] According to the support pad assembly 1 of the present invention, when the inflatable component 200 is in the deflated state, the inflatable component 200 can be completely retracted into the mounting cavity 110. That is, the inflatable component 200 occupies less space after deflation and retraction, and the inflatable component 200 does not need to provide support in the deflated state. The elastic substrate 100 can form independent support by relying on its own elastic deformation. Specifically, the elastic substrate 100 can achieve independent load-bearing by utilizing the hollow mounting cavity 110 and the low bending stiffness characteristics of the elastic ribs 120. When a passenger sits down, the mounting cavity 110 can be flattened along the force direction, while the elastic ribs 120 bend and deform and absorb energy. This can convert the impact pressure of the passenger sitting down and the road bumps into elastic deformation energy, thereby enabling the elastic substrate 100 to independently buffer and absorb energy.

[0034] Furthermore, when the inflatable component 200 is inflated, the elastic matrix 100 can work together with the inflatable component 200 to form a composite support. Specifically, after inflation, the inflatable component 200 expands and fits against the inner wall of the mounting cavity 110. In this way, the inflatable component 200 can apply a reverse thrust to the upper and lower walls of the mounting cavity 110 to resist compression deformation, thereby suppressing the bending amplitude of the elastic ribs 120 and significantly improving the overall support stiffness of the support pad assembly 1. At this time, the support pad assembly can provide more stable positioning and support for the driver and passengers, effectively controlling the displacement amplitude of the human body on bumpy roads or during emergency braking, reducing body sway, and thus improving driving safety.

[0035] In other words, compared to the support cushions of traditional seats, the support cushion assembly 1 of this invention can construct two support methods: independent support by the elastic base 100 and collaborative support by the elastic base 100 and the inflatable component 200. The support cushion assembly 1 can have two different support characteristics, thereby enabling the same support cushion assembly 1 to freely switch between soft comfort and high support firmness, resulting in a better user riding experience. Moreover, by forming elastic ribs 120 between at least two adjacent mounting cavities 110, not only can the deformation of the elastic ribs 120 generate support force, but the elastic ribs 120 can also form a constraint structure on the inflatable component 200, preventing the inflatable component 200 from shifting position, thereby ensuring the structural stability of the support cushion assembly 1. Even after long-term use, the inflatable component 200 and the elastic base 100 can still maintain their relative positions, thus preventing irregular deformation of the support cushion assembly 1.

[0036] Thus, the support pad assembly 1 according to the present invention can take into account both the support characteristics of the elastic base 100 bearing alone and the elastic base 100 and the inflatable component 200 bearing together, resulting in a better user experience and higher comfort. It also helps to improve the load-bearing stability of the support pad assembly 1, making the support pad assembly 1 less prone to irregular deformation and more reliable even after long-term use.

[0037] More importantly, the support pad assembly 1 of the present invention not only upgrades the riding comfort, but is also a key part of the intelligent driving ecosystem. By deeply integrating it with the intelligent driving and intelligent cockpit systems, it can link with intelligent driving and intelligent cockpit, and then actively adjust the air pressure of the inflator 200 in real time according to the vehicle's driving status, the size of the occupants, the occupants' sitting posture, or the road conditions, so as to provide more reliable and comfortable underlying support for intelligent driving.

[0038] Specifically, in the intelligent cockpit system, the support pad assembly 1 can be connected to the cockpit occupant sensing module. Based on the occupant's body characteristics, sitting habits, and real-time pressure distribution data output by the sensing module, it can automatically generate independent inflation and deflation strategies for each inflatable component, enabling zoned fine-tuning of the seat support surface to adapt to the personalized comfort needs of different occupants. Simultaneously, the support pad assembly 1 can be linked with the health monitoring system within the intelligent cockpit. When it detects that an occupant has maintained the same sitting posture for an extended period, it can periodically inflate and deflate the inflatable components 200 according to a set sequence, dynamically changing the support point position to proactively manage health by relieving muscle pressure and promoting local blood circulation.

[0039] In addition, in intelligent driving scenarios, the air pressure of each inflatable component 200 can be adjusted in real time according to the vehicle's driving status (such as acceleration, braking, steering, or switching of autonomous driving mode), thereby actively changing the local stiffness and support profile of the support pad assembly 1, so as to provide occupants with lateral support and lumbar support that are adaptive to the vehicle's posture during dynamic driving, thereby improving the safety and comfort of riding during intelligent driving.

[0040] Furthermore, under the coordinated control of intelligent driving and intelligent cockpit, the stiffness and support distribution of the inflatable component 200 can be adjusted in advance based on the road condition prediction information from the navigation system and advanced driver assistance system when it is predicted that the vehicle will be passing through curves, bumpy road sections, or performing automatic lane change operations. This allows the support response of the seat 2 to precede the dynamic movements of the vehicle, realizing an intelligent comfort support strategy of "pre-sensing-pre-adjustment" and further enhancing the overall intelligent experience of the vehicle.

[0041] In some specific embodiments of the present invention, such as Figures 3-5 As shown, an elastic rib 120 is formed between two adjacent mounting cavities 110, and / or an elastic rib 120 is formed between the mounting cavity 110 and the side of the elastic base 100.

[0042] By providing elastic ribs 120 between two adjacent mounting cavities 110 and between the mounting cavity 110 and the side of the elastic base 100, the number of elastic ribs 120 can be large and the distribution relatively uniform. The elastic ribs 120 can serve as connecting and supporting structures. When the support pad assembly 1 is subjected to load, it can provide elastic support force through bending deformation, thereby avoiding excessive compression of the elastic base 100 when the inflatable component 200 is in a deflated state, so as to ensure that the elastic base 100 can provide reliable support force, thereby ensuring that the overall load-bearing capacity of the support pad assembly 1 is relatively stable.

[0043] In some specific embodiments of the present invention, such as Figure 3 As shown, the diameter of the mounting cavity 110 is D, and the distance between the central axes of two adjacent mounting cavities 110 is L, where D and L satisfy: D < L ≤ 2D. In other words, the minimum thickness of the elastic rib 120 can be greater than 0 and not greater than D.

[0044] For example, the distance L between the central axes of two adjacent mounting cavities 110 can be 1.1D, 1.2D, 1.3D, 1.4D, 1.5D, 1.6D, 1.7D, 1.8D, 1.9D, or 2D.

[0045] Preferably, the number of mounting cavities 110 provided on the elastic substrate 100 does not exceed 8.

[0046] It is understandable that since an elastic rib 120 is formed between two adjacent mounting cavities 110, the minimum thickness of the elastic rib 120 is defined by the two adjacent mounting cavities 110. By limiting the distance L between the central axes of the two adjacent mounting cavities 110 to be greater than the diameter D of the mounting cavity 110, it can be ensured that the minimum thickness of the elastic rib 120 is greater than 0. That is, it can be ensured that an elastic rib 120 can be formed between the two adjacent mounting cavities 110, so as to generate elastic support force by utilizing the deformation of the elastic rib 120.

[0047] Preferably, 1.3D≤L, which ensures that the minimum thickness of the elastic rib 120 is not less than 0.3D, so as to avoid the minimum thickness of the elastic rib 120 being too small. The elastic rib 120 itself can have greater support strength and elastic recovery force. When the inflatable component 200 is in the deflated state, the elastic matrix 100 can still provide sufficient support force, thereby avoiding excessive local collapse or complete collapse of the support pad assembly 1, so as to ensure good load-bearing stability and support continuity of the support pad assembly 1.

[0048] In addition, by limiting L≤2D, the minimum thickness of the elastic rib 120 can be avoided from being too large. On the one hand, this can prevent the elastic substrate 100 from becoming too rigid due to excessive thickness of the elastic rib 120. On the other hand, it can prevent the elastic rib 120 from occupying too much space on the elastic substrate 100, so that the elastic substrate 100 can have more space to construct the installation cavity 110, thereby allowing multiple inflatable components 200 to be installed. Multiple inflatable components 200 can work together to provide support, ensuring that the support pad assembly 1 has high support and better support stability.

[0049] In some specific embodiments of the present invention, such as Figures 3-5 As shown, the thickness of the elastic substrate 100 is H, the diameter of the mounting cavity 110 is D, and H and D satisfy: H / 3≤D≤2H / 3.

[0050] For example, the diameter D of the mounting cavity 110 can be H / 3, 4H / 9, 5H / 9 or 2H / 3.

[0051] The thickness H of the elastic substrate 100 can be 30mm to 80mm. This avoids the elastic substrate 100 being too thick and occupying too much installation space, making it easier to arrange. At the same time, it also avoids the elastic substrate 100 being too thin, so as to ensure that the elastic substrate 100 has good elastic recovery ability, thereby ensuring that the support pad assembly 1 has good support ability.

[0052] Furthermore, by limiting H / 3≤D≤2H / 3, this avoids two problems. First, it prevents the diameter of the mounting cavity 110 from being too large, which would cause a significant decrease in the overall hardness of the elastic matrix 100. The elastic matrix 100 can still provide reliable elastic support. Second, it avoids the diameter of the mounting cavity 110 from being too small, which would prevent the volume of the inflatable component 200 installed in the mounting cavity 110 from being too small. This allows the effective inflation volume and support area of ​​the inflatable component 200 to be larger, enabling it to provide sufficient support and better support adjustment. As a result, the inflatable component 200 can form a composite support with the elastic matrix 100.

[0053] In some specific embodiments of the present invention, such as Figures 3-5 As shown, the mounting cavities 110 extend horizontally, and the central axes of the multiple mounting cavities 110 are in the same horizontal plane. This configuration allows the inflatable components 200 disposed within the multiple mounting cavities 110 to be at the same height, and the multiple inflatable components 200 to produce similar support effects at different positions. This improves the deformation consistency and load-bearing balance of the multiple inflatable components 200 under pressure, ensuring that the support effect at different positions of the support pad assembly 1 is the same.

[0054] Furthermore, the multiple mounting cavities 110 are arranged along the length or width of the elastic substrate 100, and the central axes of the multiple mounting cavities 110 are parallel. This allows the support pad assembly 1 to form a regular distribution structure of mounting cavities 110, ensuring that the inflatable components 200 disposed in each mounting cavity 110 have a more consistent arrangement direction and stress deformation trend, thereby facilitating the coordinated load-bearing capacity of multiple inflatable components 200. At the same time, the elastic ribs 120 formed between adjacent mounting cavities 110 can extend in the same or similar directions, which is conducive to forming a continuous or near-continuous elastic load-bearing structure and reducing local stress concentration or uneven deformation caused by irregular cavity arrangement.

[0055] Furthermore, the multiple mounting cavities 110 are evenly spaced, which ensures that the elastic ribs 120 formed between adjacent mounting cavities 110 have consistent or substantially consistent dimensions, thereby making the material distribution and elastic support performance inside the support pad assembly 1 more balanced. At the same time, the inflatable components 200 in each mounting cavity 110 can obtain more consistent installation space and pressure deformation conditions, which is beneficial to improving the consistency of the cooperative bearing capacity between the multiple inflatable components 200 and the multiple elastic ribs 120, and reducing the risk of sudden changes in local stiffness or uneven deformation in the support pad assembly 1.

[0056] In some specific embodiments of the present invention, such as Figure 2As shown, the support pad assembly 1 also includes an inflation line 300, which is adapted to be connected to an inflation adjustment device, and the inflation line 300 is provided with multiple inflation ports 310, with multiple inflation components 200 connected to the multiple inflation ports 310 in a one-to-one correspondence.

[0057] The mounting cavity 110 can penetrate one end of the elastic base 100, or the mounting cavity 110 can penetrate both ends of the elastic base 100, so as to install the inflatable component 200 into the mounting cavity 110, thereby simplifying the assembly steps of the inflatable component 200 and the elastic base 100.

[0058] By setting up an inflation pipe 300 and an inflation interface 310 connected to the inflation component 200, gas can be injected into the inflation component 200 through the inflation pipe 300, or the gas inside the inflation component 200 can be discharged through the inflation pipe 300, thereby adjusting the air pressure of the inflation component 200 to achieve continuous adjustment between soft and hard states of the support pad assembly 1, so that the support pad assembly 1 can adapt to different usage requirements.

[0059] Furthermore, multiple inflatable components 200 are connected in series. For example, an inflation pipe 300 extends along the arrangement direction of multiple mounting cavities 110, and multiple inflation ports 310 can be spaced apart on the inflation pipe 300. The multiple inflatable components 200 are connected to the multiple inflation ports 310 in a one-to-one correspondence, so that the multiple inflatable components 200 can be inflated or deflated through the same inflation pipe 300. With this arrangement, multiple inflatable components 200 can be inflated or deflated through one inflation pipe 300, thereby achieving synchronous inflation or deflation of the inflatable components 200. The air circuit structure is simpler, which helps to simplify the structure of the support pad assembly 1.

[0060] In other embodiments, multiple inflatable elements 200 are arranged in parallel.

[0061] For example, the inflation line 300 may be provided with multiple inflation ports 310 at intervals, and each inflation port 310 is provided with a corresponding control valve. That is, each control valve can control the opening and closing of the corresponding inflation port 310, thereby enabling independent inflation and deflation of multiple inflation components 200.

[0062] Alternatively, the support pad assembly 1 can be provided with multiple inflation lines 300, and the inflation adjustment device can be connected to multiple inflation components 200 one by one through the multiple inflation lines 300, so that the multiple inflation components 200 can also be connected in parallel.

[0063] By connecting multiple inflatable components 200 in parallel, not only can the synchronous inflation or deflation of multiple inflatable components 200 be achieved, but also the inflatable components 200 at different positions can be adjusted independently. This enables zoned control of the support pad assembly 1, that is, the softness and hardness of different positions of the support pad assembly 1 can be adjusted separately, which is beneficial to improving the adjustment flexibility of the support pad assembly 1.

[0064] In some specific embodiments of the present invention, such as Figures 3-5 As shown, the elastic matrix 100 is also provided with a plurality of deformation holes 130, which are correspondingly provided with the elastic ribs 120.

[0065] For example, the multiple deformation holes 130 can be arranged in multiple rows. One row of deformation holes 130 can be disposed adjacent to the upper side of the elastic substrate 100, and another row of deformation holes 130 can be disposed adjacent to the lower side of the elastic substrate 100. Furthermore, the deformation holes 130 can be disposed corresponding to the elastic ribs 120 in the thickness direction of the elastic substrate 100.

[0066] By providing deformation holes 130 on the elastic substrate 100 corresponding to the elastic ribs 120, the structural strength of the elastic substrate 100 at the corresponding positions of the elastic ribs 120 can be further weakened, so as to avoid excessive hardness of the elastic substrate 100 and allow the elastic substrate 100 to undergo greater elastic deformation. Whether the elastic substrate 100 supports the load alone or supports the load in conjunction with the inflatable component 200, the support comfort of the support pad assembly 1 can be improved, and the user's riding comfort can be better.

[0067] The seat 2 according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0068] like Figure 1 As shown, the seat 2 includes at least one support pad assembly 1 and an inflation adjustment device according to the above embodiments of the present invention.

[0069] The support pad assembly 1 is located inside at least one of the seat cushion 400, backrest 410, headrest 420 and leg rest 430. The inflation adjustment device is connected to the inflation component 200 of the support pad assembly 1. The inflation adjustment device is used to inflate and deflate the inflation component 200. The inflation adjustment device can adjust the air pressure of the inflation component 200, thereby adjusting the support stiffness, load-bearing state and elastic deformation performance of the support pad assembly 1.

[0070] In other words, the seat cushion 400, backrest 410, headrest 420 and leg rest 430 can all be equipped with support pad assembly 1 to support the user's buttocks, back, head and neck or legs.

[0071] For example, when the seat cushion 400 is provided with a support pad assembly 1, the seat cushion 400 may have one support pad assembly 1, that is, a whole support pad assembly 1 is used as a support member of the seat cushion 400 to support the user; or, the seat cushion 400 may have multiple support pad assemblies 1, and the multiple support pad assemblies 1 can be arranged horizontally to work together as a support member of the seat cushion 400 to support the user.

[0072] According to the embodiment of the present invention, the seat 2, by utilizing the support pad assembly 1 proposed in the above embodiment of the present invention, can take into account both the support characteristics of the elastic base 100 bearing alone and the elastic base 100 and the inflatable component 200 bearing together, resulting in a better user experience and higher comfort. It also helps to improve the load-bearing stability of the support pad assembly 1, making the support pad assembly 1 less prone to irregular deformation and more reliable even after long-term use.

[0073] In this embodiment of the invention, the seat 2 can form different support modes according to different air pressure states of the inflatable component 200. For example, the seat 2 can have a soft and comfortable mode, a high support and firm mode, and a continuously adjustable soft and firm mode.

[0074] Specifically, when the seat 2 is in the soft and comfortable mode, the inflatable component 200 has no air pressure or only a very low pressure, that is, the inflatable component 200 is in a deflated state, and the elastic matrix 100 remains in its original state. When the passenger sits down, the seat cushion 400 is subjected to vertical pressure, and the elastic matrix 100 is compressed. However, at this time, the inflatable component 200 does not provide additional support. The stiffness of the seat cushion 400 is entirely determined by the material of the elastic matrix 100 and the structure of the elastic ribs 120. Overall, it is relatively soft and has strong cushioning, which can effectively disperse pressure.

[0075] When seat 2 is in the high-support firm mode, the inflation adjustment device injects high-pressure gas into multiple inflation components 200 through the inflation pipe 300. The inflation components 200 expand and fit tightly against the inner wall of the mounting cavity 110, pushing the mounting cavity 110 back to its original circular shape. At this time, when the passenger sits down, the inflation components 200 form rigid support, limiting the amount of compression deformation of the elastic base 100, and the bending amplitude of the elastic ribs 120 is greatly reduced. The mounting cavity 110 is hardly flattened. Under the combined action of the expansion support of the inflation components 200 and the elastic base 100, the overall support stiffness of the seat cushion 400 is significantly improved, exhibiting a firmer and more supportive performance.

[0076] When seat 2 is in the continuously adjustable firmness mode, the user can send adjustment commands to the inflation adjustment device through the control interface (such as the adjustment buttons on seat 2 or the vehicle's infotainment screen). Upon receiving the signal, the inflation adjustment device precisely controls the opening and closing time of the intake / exhaust valves. Specifically, when the seat cushion 400 needs to be softened, the inflation adjustment device slowly releases the gas inside the inflation component 200, gradually reducing the air pressure. Consequently, the support force of the inflation component 200 decreases, the compressibility of the elastic matrix 100 gradually increases, and the stiffness of the seat cushion 400 smoothly decreases. Conversely, when the seat cushion 400 needs to be hardened, the inflation adjustment device slowly inflates the inflation component 200, gradually increasing the air pressure. Consequently, the support force of the inflation component 200 increases, the compressibility of the elastic matrix 100 gradually decreases, and the stiffness of the seat cushion 400 smoothly increases. Furthermore, after adjustment, the inflation adjustment device maintains the target air pressure inside the inflation component 200 through a pressure-holding valve, ensuring that the firmness of the seat cushion 400 remains stable.
