Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to a cushion mechanism, a seat, and a vehicle. Background Art

[0002] With the rapid development of the new energy vehicle industry, users' requirements for vehicle quality are constantly increasing. Among them, seats are the most direct and high-frequency contact points between drivers and passengers and vehicles. Their comfort, safety and long-term impact on human health have gradually become important reference factors for measuring the comfort performance and ergonomic level of the vehicle.

[0003] However, existing car seats still lack ride comfort in practice. This is particularly true during extended driving or frequent starting and braking, which can lead to driver discomfort and fatigue. To alleviate this discomfort, drivers often adjust the contact position of their buttocks on the seat to redistribute pressure and improve the ride experience. However, these adjustments can cause a brief distraction, potentially compromising driving safety. Summary of the Invention

[0052] In some embodiments, when the vehicle is in an emergency state, the speed at which the charging and discharging module drives the fluid to be discharged from the first bladder is faster than the speed at which the charging and discharging module drives the fluid to be injected into the first bladder.

[0053] In some embodiments, when the vehicle is in an emergency state, the time it takes for the charging and discharging module to drive the first bag to empty is less than or equal to 4 seconds.

[0054] In some embodiments, the seat cushion mechanism further includes a second sensor, the second sensor being configured to detect an emergency state of the vehicle;

[0061] According to a third aspect of the present application, a vehicle is also provided, comprising the cushion mechanism described in the above technical solution, or the seat described in the above technical solution.

[0062] The seat cushion mechanism of this embodiment of the present application, through the provision of a first bladder, provides flexible support in multiple directions for the buttocks. When compressed, the first bladder generates an elastic support reaction force, creating a multi-directional restraining effect on the buttocks, thereby stabilizing the relative position of the buttocks on the seat to a certain extent. This stability helps reduce changes in the support area caused by buttocks movement, reducing the likelihood of ride discomfort during dynamic driving.

[0063] The first bladder forms a horizontally enclosing and restricting structure, providing a snug, restraining, and supporting effect on the user's buttocks. This continuously applies a corresponding flexible guiding force to the user's buttocks during use, keeping them within a relatively reasonable seating area. This helps the user maintain a stable and comfortable sitting posture, reducing the need for frequent posture adjustments due to sitting deviations, and thus improving posture retention during long rides.

[0064] In addition, by controlling the charging and discharging module through the control module, the filling degree of the first bladder can be adjusted, so that the fitting effect of the first bladder is better, thereby achieving an adaptive distribution of support force, which helps to alleviate the fatigue risk caused by local high-pressure areas and is suitable for alleviating physical fatigue caused by uneven support distribution during long-term riding.

[0065] Since the limiting effect provided by the first bladder can inhibit the free displacement of the buttocks on the seat and prevent the buttocks from sliding and causing the sitting posture to drift, it can reduce the driver's attention distraction caused by frequent body movements to adjust the posture, which to a certain extent helps to reduce the safety hazards caused by the ride.

[0066] Other features and advantages of the present application will be described in detail in the subsequent detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0084] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0085] According to the first aspect of the present application, the present application provides a cushion mechanism 11, which is applied to a seat 10. Figure 1 、 Figure 8, for example, it can be applied to a car seat 10 or a massage seat 10. It is understood that the cushion mechanism 11 can be integrated into the frame of the seat 10, or can be assembled with the seat 10 body in a modular structure in a detachable manner, thereby having a certain degree of installation flexibility and facilitating the adaptation of different types of seats 10.

[0086] In some embodiments, reference Figure 2 、 Figure 3 The cushion mechanism 11 includes a cushion body 11a, a first capsule 100, a charging and discharging module 200 and a control module 300 (combined with Figure 5 ). The seat cushion body 11a has a seating surface 11a1, which is suitable for contacting the buttocks of the seated person after the seat is seated, thereby providing support for the seated person. The control module 300 is connected to the charging and discharging module 200, and is used to control the charging and discharging module 200 to adjust the first bladder 100 so that the first bladder 100 supports the buttocks of the seated person and limits the position of the buttocks relative to the seat cushion body 11a in multiple directions on the seating surface 11a1. In some examples, the first bladder 100 can be disposed within the seat cushion body 11a, and the seat cushion body 11a is used to provide a mounting base for the first bladder 100.

[0087] In some examples, the first bladder 100 can be constructed as a flexible air bladder or a flexible liquid bladder. For example, the flexible air bladder can be constructed from multiple layers of elastic material, at least one of which is a thermoplastic polyurethane film to provide airtightness. Liquid bladders can also adopt a similar structure, using corrosion-resistant materials to accommodate the storage requirements of different liquid types. Through the inflation and deformation of the flexible material, the first bladder 100 can produce a certain degree of compliant deformation under load, generating a reaction force, thereby providing flexible support for the occupant.

[0088] Specifically, the gas or liquid carried by the first bladder 100 can be a medium with a certain temperature. For example, in cold weather, the first bladder 100 can be filled with higher-temperature air or liquid. When the first bladder 100 is in contact with the occupant, a certain degree of heating effect is achieved, alleviating the discomfort caused by the low temperature. In hot weather, a relatively low-temperature medium can be filled to form a cooling area, thereby reducing the stuffy feeling during riding.

[0089] In some examples, the first bladder 100 is movably mounted on the seat 10 (not shown). For example, the first bladder 100 is mounted within a guide rail structure, a guide slot, or a flexible sliding cavity, and can be adjusted in a predetermined direction. The first bladder 100 is a flexible support structure, and its outer shell can be made of a flexible material such as rubber, a thermoplastic elastomer, or a flexible composite film. This allows for a certain degree of elastic deformation after being filled or released, thereby providing a flexible and conformable support force for the seated person's buttocks.

[0090] During use, the control module 300 can pre-adjust the first bladder 100 before the passenger takes the seat, for example, by automatically initiating a pre-filling process through a seating sensor or based on user-set data, so that the first bladder 100 moves forward to the appropriate position. In this way, when the passenger actually takes the seat, the first bladder 100 can immediately provide a snug support for the buttocks.

[0091] This method of adjusting the position of the first bladder 100 by moving it helps achieve more stable positioning of the buttocks. On the one hand, it can reduce the tendency of the buttocks to slip under dynamic driving conditions, thereby improving sitting stability. On the other hand, by adjusting the position of the bladder to adapt to the sitting posture of users of different body shapes, it also helps to improve the targeted support and comfort.

[0092] In some examples, the first bag 100 is movably provided on the seat 10 (not shown in the figure), and the first bag 100 is an inflatable bag. The charging and discharging module 200 can inflate the first bag 100 or drive it to move within a preset range, so that the first bag 100 is close to the user's buttocks to provide flexible support and multi-directional limitation, which helps to improve the wrapping feeling of the buttocks and the sitting stability.

[0093] As can be understood, the first bladder 100 is used to provide flexible support for the seated person's buttocks and to constrain the position of the buttocks relative to the seat cushion body 11a in multiple directions on the seating surface 11a1. Specifically, when inflated, the first bladder 100 conforms to the buttocks and is structurally located on or near the seat cushion surface of the seat 10 to achieve both support and position limiting functions.

[0094] The "multiple directions" may include at least the direction toward the front of the seat 10, and the left and right directions of the seat 10. In other words, the first bladder 100 may be configured to partially cover the buttocks. After expansion and deformation, it can provide a certain degree of reactive support force when the user deviates forward, left, or right, thereby preventing the buttocks from sliding or deviating significantly relative to each other.

[0095] Through this arrangement, the first bladder 100 provides stable support for the seated occupant's buttocks while also minimizing any changes in sitting posture caused by buttock displacement during vehicle operation or posture adjustments. This maintains a certain degree of seating consistency and enhances both stability and comfort. This multi-directional retaining structure effectively mitigates inertial shifts during acceleration, steering, or deceleration, improving the support and wrapping performance of the seat 10.

[0096] It should be noted that the "restriction" here should be understood as a deformable support constraint generated by the flexible structure. It is neither a rigid limit nor does it completely inhibit all hip movement. Instead, it uses the elastic structure to generate a certain reaction force in multiple directions to inhibit relative displacement, thereby achieving the goal of supporting and stabilizing posture. This structural design is beneficial for improving the seat 10's ability to support the hip area without interfering with the user's natural posture changes.

[0097] In some embodiments, the first bladder 100 is configured to expand after fluid is injected, and the filling state is adjustable. The charging and discharging module 200 is configured to drive the fluid to be injected into or discharged from the first bladder 100 to adjust the filling state of the first bladder 100.

[0098] In some examples, the first bladder 100 can be a sealed cavity made of a flexible material. This structure can deform and expand when a fluid (including gas or liquid) is injected into it, thereby providing flexible support for the contact area. The first bladder 100 can be positioned on the seat cushion surface of the chair 10 or in an area near the seat cushion surface. Its location can be designed to be close to the user's buttocks area to improve the fit and effectiveness of the support.

[0099] Exemplarily, the charging and discharging module 200 is connected to the first bladder 100 and is used to control the injection or discharge of gas or liquid into the first bladder 100 to adjust the filling state of the first bladder 100. The charging and discharging module 200 may include a pump body, a valve body, and related fluid connection pipelines. The pump body can be an air pump or a liquid pump, and the specific configuration can be based on the usage scenario. For example, using a micro air pump can simplify the structure and improve the response speed.

[0100] When a user sits in the seat 10, the control module 300 triggers the charging and discharging module 200 based on a preset program or sensor signal, causing the first bladder 100 to expand to a set degree, forming a resilient support surface that can locally deform according to the user's body shape and posture, thereby achieving multi-directional support for the hip area and a certain degree of position limiting effect. Because the inflated first bladder 100 has a certain degree of rigidity, it can generate a counter-support force against the horizontal or tilted displacement trend of the hip, thereby limiting the free displacement of the hip relative to the seat 10 to a certain extent, thereby helping to maintain the stability of the sitting posture and reducing the discomfort or driving interference caused by frequent adjustments to the sitting posture.

[0101] Furthermore, the filling level of the first bladder 100 can be adjusted in real time based on user preferences or driving conditions to accommodate different body shapes and comfort needs. During dynamic driving, adjusting the bladder's filling level can improve the support's compliance and wrapping properties, thereby mitigating vibration transmission and enhancing the overall ride experience.

[0102] In some embodiments, reference Figure 2 、 Figure 3 When the first bladder 100 is inflated, a side of the first bladder 100 forms an accommodation space 120 for accommodating at least a portion of the buttocks. Specifically, the first bladder 100 is at least partially arranged around the accommodation space 120 and restricts the position of the buttocks relative to the seat cushion body 11a in multiple directions to provide stable support for the buttocks.

[0103] It will be appreciated that the provision of the accommodating space 120 provides a certain degree of restraint and support for the buttocks when they enter the accommodating space 120, thereby reducing unnecessary displacement of the buttocks on the seat 10. The first bladder 100 is arranged around the accommodating space 120 and can be inflated with air or liquid to form a flexible support structure, supporting the buttocks and restricting their relative movement in multiple directions. These multiple directions may include at least directions toward the front, left, and right sides of the seat 10.

[0104] In some examples, reference Figure 2 、 Figure 3The first bladder 100 can independently enclose the accommodation space 120, for example, by forming the boundary of the accommodation space 120 through the expansion shape of the inflatable bladder, thereby achieving the functions of support and limitation. In other examples, the first bladder 100 is jointly enclosed with other components of the seat 10 to form the accommodation space 120. For example, the first bladder 100 is arranged in the front and left and right directions of the seat 10, and together with the back of the seat 10, forms the accommodation space 120, thereby achieving support and limitation for the buttocks. The arrangement of the first bladder 100 and its combination with other components of the seat 10 can be flexibly adjusted according to actual needs to achieve the best support effect.

[0105] It is further understood that the physical structure formed around the accommodating space 120 can be continuous or discontinuous. For example, the accommodating space 120 can be surrounded by two opposing first airbags. Such a structural design can provide partial or full support as needed and limit the sliding and displacement of the buttocks to a certain extent, thereby enhancing the stability and comfort of the seat 10.

[0106] The presence of the accommodating space 120 and the arrangement of the first sac 100 provide the seat 10 with better buttocks support and limiting effects, which is beneficial to improving comfort under long-term sitting, reducing discomfort and improving riding stability, especially in dynamic driving conditions, and can effectively reduce the frequency of sitting posture adjustment caused by buttocks displacement.

[0107] In some embodiments, reference Figure 2 、 Figure 3 The first bladder 100 encloses and forms an accommodation space 120. This approach creates a simple and compact structural design, making the overall layout of the seat cushion mechanism 11 more compact and easier to control. The first bladder 100, acting as a flexible support structure, can precisely adjust the size and shape of the accommodation space 120 by expanding or contracting, effectively controlling the support and positioning of the buttocks.

[0108] In some embodiments, there are at least two first sacs 100, and at least two first sacs 100 form a ring. The accommodation space 120 of the cushion mechanism 11 is located on the inner side of the ring formed by the at least two first sacs 100. Through this design, the first sacs 100 can be adjusted separately, so that different first sacs 100 have different filling states. The multiple first sacs 100 form an annular structure, which can effectively provide more uniform and comprehensive support and limiting effects. The arrangement of multiple first sacs 100 can not only support the buttocks in multiple directions, but also form a more stable accommodation space 120 through the annular enclosure structure, thereby effectively limiting the position of the buttocks relative to the cushion body 11a.

[0109] Specifically, the annular design of at least two first bladders 100 can form a more precise support area based on the contours of the user's buttocks, improving the comfort and stability of the seat 10. The annular structure can evenly distribute pressure on the buttocks through multiple points of support, effectively avoiding pressure concentration in a single direction and reducing fatigue caused by long-term riding.

[0110] Furthermore, because the multiple first bladders 100 form a ring, the structure is more flexible, allowing the expansion state of the first bladders 100 to be adjusted as needed, enabling fine-tuning of the size and support strength of the accommodating space 120. This design further enhances the adaptability and comfort of the seat 10, especially during dynamic driving and long rides, effectively stabilizing the hip position and avoiding the discomfort caused by frequent adjustments to the sitting position.

[0111] In some embodiments, reference Figure 2 、 Figure 3 The ring formed by at least two first bladders 100 is an open-loop structure. As will be appreciated, the open-loop structure takes into account the varying support requirements of different areas of the buttocks. Therefore, the ring formed by at least two first bladders 100 is designed as an open-loop structure, with the open-loop areas located in areas not requiring contact with the first bladders 100. This allows the first bladders 100 to provide effective support in areas requiring support while avoiding unnecessary contact or pressure with areas of the buttocks that do not require contact.

[0112] Specifically, the open-loop structure makes the seat 10 more ergonomically designed for support, particularly by providing more precise support areas to accommodate the varying hip contours of different users. By designing open-loop areas where contact is not necessary, discomfort or pressure points caused by excessive contact are avoided, enhancing ride comfort.

[0113] In some embodiments, reference Figure 2 、 Figure 3 There are two first bladders 100, both of which are open-loop structures. The open loops of the two first bladders 100 are arranged opposite each other, forming a ring. This design corresponds to the left and right buttocks respectively, which can better meet the needs of ergonomics.

[0114] Specifically, the open-loop design allows each first bladder 100 to provide support in the appropriate area, while the open loop prevents pressure from being applied to areas that do not require contact. By positioning the open loops of the two first bladders 100 opposite each other, more balanced support for the buttocks is achieved, avoiding undue pressure on the buttocks. The ring-shaped design further enhances support stability, allowing the seat 10 to effectively restrict the buttocks' position in multiple directions.

[0115] Another advantage of this design is the ease of adjusting hip support for each side. Because the left and right hip support are provided by two separate bladders, each side can be adjusted individually, ensuring optimal hip height and support. This independent adjustment not only improves comfort but also adapts to users of varying body shapes, enhancing the adaptability and flexibility of chair 10.

[0116] In some embodiments, the accommodating space 120 includes a first space 123 and a second space 124. One first capsule 100 is arranged to form the first space 123, and another first capsule 100 is arranged to form the second space 124. The first space 123 is used to correspond to one side of the buttocks of the seated person, and the second space 124 is used to correspond to the other side of the buttocks of the seated person.

[0117] Specifically, although the first space 123 and the second space 124 are enclosed by the first bladder 100, they are not completely isolated from each other but are interconnected, so that the two spaces form a unified support area to a certain extent. This design is more ergonomic, helps to fit the overall shape of the buttocks, and provides more balanced and comfortable support.

[0118] This interconnected design allows for a better transition of support forces on both sides, thereby avoiding localized over-support or uneven support. Furthermore, the design of the accommodation space 120 allows the buttocks to fit more naturally into the seat 10 during different sitting posture adjustments, improving overall comfort.

[0119] In some embodiments, reference Figure 2 、 Figure 4 The first bladder 100 includes a first bag 130 and a second bag 140. Along a first direction, at least a portion of the second bag 140 is located below the first bag 130. The control module 300 is configured to control the charging and discharging module 200 to adjust the second bag 140 so that the second bag 140 pushes the first bag 130 in the first direction. Specifically, the second bag 140 is positioned on a side of the first bladder 100 near the bottom of the seat 10. When inflated, the second bag 140 effectively changes the height of the first bladder 100. This prevents the first bladder 100 from being able to effectively support the seat when solely controlling the height.

[0120] The first bag 130 limits the position of the buttocks in the horizontal plane of the seat 10, effectively preventing the buttocks from sliding extensively on the seat 10, thereby reducing support failure caused by buttocks displacement. The second bag 140 can be adjusted to further change the height of the first bag 100, allowing it to better fit the buttocks and provide support.

[0121] Here, the “horizontal direction” should be understood as a direction parallel to the plane of the seat 10 , that is, the plane direction of the seat cushion; and the “first direction” is a direction perpendicular to and parallel to the plane of the seat 10 .

[0122] It can be understood that, in view of the differences in the size of the buttocks of different passengers, the first bag body 130 can be adjusted by controlling the charging and discharging module 200 to achieve precise control of the filling degree of the first bag body 130. When a person with a larger buttocks rides, due to the larger contact area with the first bag body 130, even if less fluid is filled in, the first bag body 130 can still provide good support and multi-directional limiting effects. For passengers with smaller buttocks, when less fluid is filled in, the first bag body 130 may not be able to effectively support the buttocks, and the limiting effect on the buttocks is weak. To this end, the charging and discharging module 200 can adjust the filling degree of the first bag body 130 according to the size of the buttocks or personal circumstances of the passengers, so as to provide appropriate support and limiting effects, ensuring that different users can get a good sitting experience and comfort.

[0123] In some embodiments, reference Figure 3 、 Figure 4 When the first bag 100 is in a filled state, a storage space 120 is formed on one side of the first bag 100. The storage space 120 is the inner area of ​​the first bag 130. In the projection of the first bag 130 and the second bag 140 along the first direction, at least part of the projection of the second bag 140 is located in the inner area of ​​the projection of the first bag 130. The first bag 130 mainly provides better support and positioning for the buttocks of different body shapes by changing its filling state, while the second bag 140 plays an auxiliary role, enhancing the contact effect between the first bag 130 and the buttocks. Specifically, the second bag 140 can adjust the position of the first bag 130 by expanding or contracting, so that the first bag 130 is closer to or farther away from the buttocks, thereby optimizing the support and positioning effects. Through this structural design, the comfort and adaptability of the chair 10 can be adjusted according to the user's body shape, ensuring that the experience of different users on the chair 10 is more ergonomic.

[0124] Positioning at least a portion of the projection of the second bag 140 inward of the projection of the first bag 130 within the seating structure's accommodating space 120 provides auxiliary support for the buttocks and prevents excessive forces between the buttocks and the first bag 130. Specifically, the presence of the second bag 140 prevents excessive localized pressure concentration when the first bag 130 contacts the buttocks, thereby improving the adaptability and comfort of the seat 10.

[0125] In some embodiments, reference Figure 2 、 Figure 4The projections of the first bag 130 and the second bag 140 along a direction perpendicular to the first direction at least partially overlap. It can be understood that the first bag 130 at least partially serves as the sidewall of the accommodating space 120. A transition zone 122 is formed between the first bag 130 and the bottom area 121 of the accommodating space 120 (i.e., the area of ​​the accommodating space 120 away from the occupants). The structure of this area is similar to the angle between the sidewall and bottom wall of a water cup. The presence of this transition zone 122 may cause the support effect of this area to be lost, resulting in discomfort.

[0126] Therefore, the projections of the first bag 130 and the second bag 140 along the first direction perpendicular to the first side at least partially overlap, effectively reducing or completely filling the transition zone 122, thereby providing more comprehensive support for the buttocks within the accommodation space 120. Adjusting the inflation or deflation of the second bag 140 provides a more uniform support force within the transition zone 122, avoiding insufficient support in certain areas and thereby improving the comfort and adaptability of the support structure of the entire seat 10. This ensures that the user's buttocks receive comprehensive support, improving the comfort of the seat 10 and preventing discomfort.

[0127] It can be understood that “at least partially overlap” means that the portion of the second bag body 140 in the accommodating space 120 overlaps with the area of ​​the first bag body 130 projected along the first direction, so that the two have a spatial correspondence in this direction.

[0128] In some embodiments, reference Figure 2 、 Figure 3 The seat cushion mechanism 11 includes a first sensor 110, which is used to collect biometrics of the seated person and / or the contact state between the seated person and the seat cushion body 11a.

[0129] The control module 300 is configured to receive signals from the first sensor 110 and control the charging / discharging module 200 to adjust the first bladder 100 based on the signals from the first sensor 110. Specifically, the biometric data of people of different body types can be pre-entered into the control module 300. When a person takes a seat, the first sensor 110 collects their biometric information, such as fingerprints and facial information, to identify the person based on this information. Based on this information, the charging / discharging module 200 is then controlled to adjust the first bladder 100 to better fit the shape of the buttocks, achieving better support and positioning.

[0130] In addition, the control module 300 can also judge the body characteristics of the current seated person based on the contact status information (such as contact area, pressure distribution, etc.) collected in real time by the first sensor 110, and dynamically adjust the filling level of the first bladder 100 accordingly to achieve adaptive support for different users, thereby improving the intelligence and comfort experience of the use of the seat 10.

[0131] In some embodiments, when a seated person applies a first pressure to the seat cushion body 11a, the control module 300 controls the charging / discharging module 200 to fill the first bladder 100 with a first amount of fluid. When a seated person applies a second pressure to the seat cushion body 11a, the control module 300 controls the charging / discharging module 200 to fill the first bladder 100 with a second amount of fluid. The first pressure is less than the second pressure, and the first amount of fluid is greater than the second amount of fluid. In other words, when a seated person is heavier, the pressure they apply to the seat cushion body 11a is greater, and accordingly, the amount of fluid filled into the first bladder 100 is reduced. This helps prevent the first bladder 100 from exerting a significant supporting reaction force on the seated person's buttocks, thereby alleviating a certain degree of localized pressure.

[0132] The first amount of fluid and the second amount of fluid refer to the volume or mass of fluid injected into the first bladder 100 by the control module 300 instructing the charging and discharging module 200. This control method dynamically adjusts the support strength of the first bladder 100 based on the different pressures generated by the different weights of seated users, thereby achieving a more balanced support distribution among different users.

[0133] In some embodiments, the first sensor 110 includes at least one of a pressure sensor, a weight sensor, a shape sensor, and a strain sensor.

[0134] By placing the aforementioned types of sensors at the contact point of the first bladder 100, the contact state between the seated person and the seat 10 can be accurately monitored. For example, a pressure sensor can be used to detect local or overall force distribution, a weight sensor can sense the seated person's overall weight, a shape sensor can sense changes in the contour of the buttocks, and a strain sensor can reflect the deformation of the bladder under stress. This information can be transmitted in real time to the control module 300, which then makes a comprehensive judgment based on the data from multiple sensors to intelligently control the inflation and deflation state of the first bladder 100. This allows the first bladder 100 to dynamically change according to different body shapes or sitting postures, providing adaptive support, thereby improving the comfort and ergonomics of the seat 10 to a certain extent.

[0135] In some embodiments, the first sensor 110 is positioned on the side of the first bladder 100 closest to the seated person's buttocks. It is understood that the first sensor 110 can alternatively be positioned on the side of the first bladder 100 away from the seated person, or within the interior space of the first bladder 100. Different positioning locations are selected based on the specific structural layout or measurement accuracy requirements, thereby effectively sensing the stress state of the seat cushion.

[0136] In some embodiments, reference Figure 4 、 Figure 5 , the first sensor 110 is arranged on the first capsule 100. By directly arranging the first sensor 110 on the first capsule 100, the contact information between the seated person and the first capsule 100, such as pressure distribution, deformation state or shape change, can be obtained more directly. Such an arrangement helps to improve the sensitivity and response speed of sensing, so that the control module 300 can quickly adjust the inflation and discharge state of the first capsule 100 based on the sensing data, thereby more accurately adapting to people of different body shapes or sitting postures, and improving the overall performance of the cushion mechanism 11 in terms of support and comfort. In specific applications, the first sensor 110 can be embedded in the outer surface, internal structure or key pressure-bearing parts of the capsule to meet different sensing needs.

[0137] In some embodiments, reference Figure 2 、 Figure 3 , the number of the first capsules 100 is at least two, and at least two first capsules 100 form an annular structure; the maximum size of the first capsule 100 in the first direction (z-axis direction in the figure) is 1-7 mm. The maximum size of the annular structure in the second direction (y-axis direction in the figure) is 350-450 mm. The maximum size of the annular structure in the third direction (x-axis direction in the figure) is 400-500 mm. Among them, the first direction, the second direction and the third direction are perpendicular to each other. Such a size setting makes the first capsule 100 present a flat structural feature. The first direction is the thickness direction, and its size is relatively small, which is convenient for achieving effective support function while keeping the overall structure compact. The second direction and the third direction correspond to the front and rear extension directions and the left and right extension directions of the seat 10, respectively, so that the annular structure surrounded by the first capsule 100 can cover the main contact area of ​​the buttocks and meet the support and limitation requirements for the buttocks. The above-mentioned size design facilitates the installation and integration of the first capsule 100 without causing major changes to the original seat 10 structure. It has good compatibility and is suitable for structural improvement or functional upgrade scenarios of existing seat 10 products.

[0138] It can be understood that the "maximum size" referred to here refers to the ultimate external size reached under structural constraints after the first sac 100 is filled with the maximum allowable amount of fluid.

[0139] Reference Figure 2 、 Figure 3 , as shown, the first direction is the z direction, the second direction is the y direction, and the third direction is the x direction.

[0140] In some embodiments, reference Figure 2 、 Figure 3 The seat cushion mechanism 11 also includes a mounting frame 400, on which at least one of the first bladder 100, the charging and discharging module 200, and the control module 300 is mounted. The provision of mounting frame 400 facilitates the unified arrangement and fixation of the multiple functional modules within the seat cushion mechanism 11, improving the coordinated stability between the modules. Furthermore, the use of mounting frame 400 facilitates the modular design of the structure, making the assembly, disassembly, maintenance, and replacement of the various components more convenient, thereby improving overall assembly efficiency and reducing subsequent maintenance costs.

[0141] In some embodiments, reference Figure 2 、 Figure 3 The seat cushion mechanism 11 further includes a massage assembly 500. When the first bladder 100 is inflated, a side of the first bladder 100 forms an accommodating space 120. The massage assembly 500 is disposed within the accommodating space 120 and is configured to massage the buttocks. The massage assembly 500 provides massage stimulation to the buttocks during seating, promoting blood circulation, relieving fatigue, and, to a certain extent, improving buttock contour and achieving a beautiful buttocks appearance.

[0142] Furthermore, because the massage component 500 is located within the accommodating space 120, it maintains a relatively stable contact with the buttocks, preventing the buttocks from slipping during the massage process and causing the massage position to shift. This facilitates targeted massage of specific areas of the buttocks, improving the effectiveness and comfort of the massage. Furthermore, the accommodating space 120 itself provides a certain positioning function for the buttocks, helping to ensure that the buttocks remain relatively stationary in the desired position. This provides structural support for the directional drive and regular control of the massage component 500, further enhancing the targeted and precise massage effect.

[0143] In some embodiments, reference Figure 2 、 Figure 3 The massage component 500 includes: a tapping component 510, which is used to tap the buttocks to simulate the patting action in manual massage, which helps to promote local blood circulation in the buttocks, relieve muscle tension, and enhance the user's massage experience.

[0144] In some embodiments, a vibration assembly 520 is used to drive at least one of the massage assembly 500 and the first bladder 100 to vibrate. This enhances the rhythmic and penetrating nature of the tapping action while achieving a dynamic massage effect, contributing to deep tissue stimulation. Specifically, the vibration assembly 520 can independently act on the first bladder 100, causing it to coordinate with the dynamic deformation of the buttocks to a certain extent, or it can work in conjunction with the tapping assembly 510 to produce a complex massage stimulation, enhancing the diversity and comfort of the overall massage.

[0145] In some embodiments, the tapping assembly 510 includes at least two tapping members 511, each of which is configured to tap the buttocks. Specifically, the at least two tapping members 511 can coordinate movements according to a predetermined pattern or rhythm to mimic the natural motion of a human hand tapping the buttocks. This design can enhance the massage effect, providing a more manual massage experience, thereby increasing the user's comfort and relaxation.

[0146] In some embodiments, at least two tapping members 511 are used to alternately tap the user's buttocks. Specifically, the two tapping members 511 can perform alternating tapping movements at a predetermined rhythm and frequency, simulating the natural alternating tapping movements of a hand massage. This alternating tapping method effectively simulates the effects of manual massage, stimulating different areas of the buttocks, helping to relax muscles and relieve fatigue. Furthermore, the alternating tapping design avoids localized overstimulation caused by a single tapping method, thereby improving comfort and massage effectiveness.

[0147] In some embodiments, reference Figure 2 、 Figure 3 The knocking member 511 includes a third bag body 511a, which is connected to the charging and discharging module 200. The control module 300 is used to control the charging and discharging module 200 to adjust the third bag body 511a so that the third bag body 511a contacts or separates from the buttocks.

[0148] In some embodiments, the charging and discharging module 200 is used to drive the injection or discharge of fluid into or out of the third bag body 511a. The third bag body 511a is configured to expand and contact the user's buttocks when the fluid is injected, and collapse and detach from the user's buttocks when the fluid is discharged. This design can provide a highly flexible massage experience, so that the tapping action can not only accurately simulate the movement of the hand, but also be adjusted according to the needs of the user, meeting the different requirements of different users for massage intensity and rhythm. Through the expansion and contraction of the third bag body 511a, the control module 300 can accurately adjust the effect of the massage, improving the comfort and effectiveness of the massage process.

[0149] In some embodiments, the charging and discharging module 200 is configured to inject the fluid into the third bag body 511 a at a speed greater than the speed at which the charging and discharging module 200 injects the fluid into the first bag body 100 .

[0150] In some embodiments, the charging / discharging module 200 is configured to expel fluid from the third bag 511a at a faster rate than the charging / discharging module 200 expel fluid from the first bladder 100. A faster rate simulates a tapping motion, resulting in a better massage effect. By increasing the rate of fluid injection or discharge, a more rapid and forceful tapping motion can be simulated, thereby enhancing the massage effect. A faster fluid flow rate enables the third bag 511a to rapidly expand and contract, simulating the tapping motion of a hand and providing a more realistic, rhythmic massage experience for the buttocks.

[0151] In some embodiments, reference Figure 3 、 Figure 7 The first bladder 100 includes a raised structure 150, which is designed to contact the buttocks. The raised structure 150 enhances the localized support provided by the first bladder 100 on the buttocks, simulating a massage effect or providing a more targeted sense of comfort. The shape and size of the raised structure 150 can be designed based on ergonomics to ensure comfortable and effective contact with the buttocks.

[0152] In some embodiments, the raised structure 150 is configured to correspond to at least one acupuncture point on the buttocks. By arranging the raised structure 150 at a specific location, specific acupuncture points on the buttocks can be stimulated, simulating the effect of massage, thereby relieving fatigue and improving blood circulation.

[0153] In some embodiments, reference Figure 3 、 Figure 7 The number of the raised structures 150 is multiple and is spaced apart on the first capsule 100. The multiple raised structures 150 are evenly distributed on the first capsule 100, which can provide more uniform support and massage effects, and can be adjusted according to needs, thereby improving comfort and effectiveness.

[0154] In some embodiments, reference Figure 3 、 Figure 7 The raised structure 150 is a hollow structure. The hollow structure can make the raised structure 150 lighter and reduce the pressure on the user, thereby better adapting to the overall design and comfort requirements of the seat 10.

[0155] In some embodiments, the raised structure 150 is elastic. The elastic raised structure 150 can provide appropriate pressure and support when contacting the buttocks, and can make corresponding adjustments with the movement of the buttocks to ensure continuous comfort and support.

[0156] In some embodiments, reference Figure 3 、 Figure 7At least the portion of the raised structure 150 that contacts the buttocks is provided with a functional layer 151. The provision of the functional layer 151 not only improves the comfort of the first bladder 100 when in contact with the buttocks, but also enhances its multifunctionality, thereby improving the overall user experience.

[0157] For example, the functional layer 151 may be a layer structure capable of heating or cooling. By adjusting the heating or cooling function of the functional layer 151, different temperature experiences can be provided according to the user's needs, helping to soothe hip muscles, promote blood circulation, or provide a cool feeling in hot weather.

[0158] In addition, the functional layer 151 can also be a massage-capable raised structure 150. These raised structures 150 can simulate a massage effect through appropriate design and layout, massaging specific areas of the buttocks to relieve fatigue and relax muscles. At the same time, when used in combination with the first capsule 100, the massage effect is more concentrated and precise.

[0159] In some embodiments, the functional layer 151 is detachably mounted on the protruding structure 150. Removing the functional layer 151 facilitates cleaning and maintenance, and different types of functional layers 151 can be replaced according to different usage requirements to meet the needs of different users.

[0160] In some embodiments, the functional layer 151 is used to apply heat or cold to the buttocks. The heat or cold compress function can provide soothing effects according to different needs. Heat can promote blood circulation, while cold can help relieve fatigue or reduce inflammation, providing users with more comprehensive care effects.

[0161] In some embodiments, the first bladder 100 has a working state and an emptying state. When the first bladder 100 is in the working state, the first bladder 100 is used to support the buttocks and limit the position of the buttocks relative to the seat cushion body 11a in multiple directions. When the first bladder 100 is in the emptying state, the first bladder 100 releases the support and restriction on the buttocks. The control module 300 is used to control the charging and discharging module 200 to discharge the fluid from the first bladder 100 when the vehicle is in an emergency state. It can be understood that in an emergency, the fluid in the first bladder 100 needs to be quickly discharged, so that the first bladder 100 can be switched to the emptying state in a short time.

[0162] In some embodiments, when the vehicle is in an emergency state, the speed at which the charging and discharging module 200 drives the fluid to be discharged from the first bladder 100 is greater than the speed at which the charging and discharging module 200 drives the fluid to be injected into the first bladder 100 .

[0163] In some embodiments, when the vehicle is in an emergency state, the time it takes for the charging and discharging module 200 to drive the first capsule 100 to empty is less than or equal to 4 seconds. For example, when the vehicle is in an emergency state, the time it takes for the charging and discharging module 200 to drive the first capsule 100 to empty is less than or equal to 3 seconds. It should be noted that the "emptying time" refers to the time required for the internal fluid of the first capsule 100 to be completely discharged after the emergency state is triggered, that is, the time period corresponding to the first capsule 100 reaching a state with basically no effective gas remaining. It should be understood that "emptying" of the first capsule 100 does not mean that its interior reaches an absolute vacuum state, but rather means that by discharging the gas therein, the volume of the first capsule 100 is significantly reduced, thereby avoiding interference with the safety function of the seat 10 when the vehicle is in an emergency state, thereby helping to reduce safety risks during use.

[0164] In some embodiments, when the vehicle is in an emergency state, the time for the charging and discharging module 200 to drive the fluid to completely discharge the first bladder 100 is equal to 3 seconds. For example, when the vehicle is in a normal state, the inflation time of the first bladder 100 is 10-12 seconds, the exhaust time is 8-10 seconds, and the inflation rate of the first bladder 100 is 1.4*10 5 mm 3 / s, the exhaust rate is 1.7*10 5 mm 3 / s. When the vehicle is in an emergency state, the inflation rate of the first bladder 100 is 4.67*10 5 mm 3 / s.

[0165] This design is particularly helpful in improving riding safety. In the event of an emergency, the fluid inside the first bladder 100 can be quickly discharged or the first bladder 100 can be removed, causing the first bladder 100 to lose its support and limit function for the buttocks. The purpose of this design is to ensure the safety of passengers in emergency situations, avoid accidental interference caused by bladder inflation or unnecessary restraint on the passenger's body, and thus reduce the potential risk of injury. In this way, the seat 10 can quickly adapt to the situation after an emergency occurs, ensuring optimal responsiveness in safety testing or actual collision accidents.

[0166] In some embodiments, reference Figure 3 、 Figure 6 The seat cushion mechanism 11 further includes a second sensor 600 for detecting a vehicle emergency state. The second sensor 600 is signal-connected to the control module 300. Upon receiving an emergency signal from the second sensor 600, the control module 300 controls the charging and discharging module 200 to adjust the first bladder 100 to an empty state. It will be appreciated that the emergency signal corresponds to a vehicle emergency state, but the emergency signal is generated when the vehicle is in an emergency state.

[0167] For example, a vehicle emergency state includes, but is not limited to, a collision, system failure, fire risk, engine stalling due to water, rollover, brake system abnormality, or other abnormal conditions that may endanger vehicle safety or the safety of occupants. It should be understood that the term "vehicle emergency state" in this embodiment refers to any of the above situations that may pose a safety risk.

[0168] This design allows the seat 10 to quickly deflate the first bladder 100 upon detecting an emergency, thereby releasing the support and restraint on the occupant's buttocks and avoiding the additional danger or interference caused by bladder inflation. This helps improve safety and reduce the risk of injury during an accident. This switching mechanism can be precisely controlled based on actual conditions, ensuring that the seat cushion mechanism 11 can quickly adapt to changing needs in the event of an accident, providing maximum protection.

[0169] For example, the second sensor 600 can output an emergency signal upon detecting that the vehicle is in an emergency state, which is used to trigger the control module 300 to respond to control related components of the seat cushion mechanism 11. The second sensor 600 can be any one of an acceleration sensor, a pressure sensor, an impact sensor, or a combination of sensors, and can detect an abnormal state when the vehicle is in an emergency state and output a corresponding emergency signal.

[0170] In some embodiments, reference Figure 3 、 Figure 6 The cushion mechanism 11 also includes a second bag 700, which is arranged in the side area of ​​the seat 10 where the cushion mechanism 11 is located. The control module 300 is used to control the charging and discharging module 200 to adjust the second bag 700 so that the second bag 700 provides support for the buttocks and / or back of the seated person.

[0171] The coordination of the first bladder 100 and the second bladder 700 provides comprehensive support for the seated occupant's buttocks and back. In certain situations, such as during turns and acceleration, dynamic real-time adjustments to the first and second bladders 100 and 700 provide enhanced dynamic support, enhancing the ride experience and improving comfort. Furthermore, the second bladder 700 can further enhance occupant stability and comfort based on the different angles of the seat 10 or usage scenarios. In particular, during driving, the support for the back and buttocks is adjusted to prevent discomfort caused by inertia during turns and acceleration.

[0172] It is understood that the "wing area" described in this embodiment refers to the location on the back, rear side, or other edge extension area relative to the main body of the seat 10. The specific definition of the wing area can be adjusted according to the actual structural layout to adapt to the installation or layout requirements of functional components.

[0173] In some embodiments, the control module 300 is connected to at least one of an accelerometer, a gyroscope, and a pressure sensor, and the control module 300 is configured to control the charging and discharging module 200 to adjust the first bladder 100 according to the signals from the accelerometer, the gyroscope, and / or the pressure sensor to provide support for the buttocks and / or back of the seated person.

[0174] As can be understood, through the accelerometer and gyroscope, the control module 300 can detect the motion state of the seat 10 (such as acceleration, braking, or turning) in real time and adjust the filling level of the bladder according to the dynamic changes of the vehicle, thereby providing more precise support for the occupant. At the same time, the pressure sensor can monitor the contact state of the occupant, ensuring that the first bladder 100 and the second bladder 700 can provide optimal support in different situations. This integrated dynamic adjustment mechanism can optimize occupant comfort and enhance the adaptability and safety of the seat 10, especially during various driving operations.

[0175] In some embodiments, reference Figure 3 、 Figure 5 The charging and discharging module 200 includes a fluid pump 210 and a silencer pot 220. The fluid pump 210 is connected to the silencer pot 220, and the silencer pot 220 is used to reduce the working noise of the fluid pump 210. By providing the silencer pot 220, the noise generated by the fluid pump 210 during the process of charging and discharging the fluid can be effectively reduced, thereby improving the comfort of the seat cushion mechanism 11. The fluid pump 210 is used to drive the injection and discharge of the fluid to ensure the rapid inflation and exhaust of the bladder, while the silencer pot 220 absorbs and attenuates the noise generated when the fluid pump 210 is working, thereby reducing its interference to the occupants and providing a quieter riding experience. The design of the silencer pot 220 enables the seat cushion mechanism 11 to maintain a low noise level when dynamically adjusting the state of the bladder, which meets the requirements of modern seat 10 design for comfort and low noise.

[0176] In some embodiments, reference Figure 3 、 Figure 6The seat cushion mechanism 11 also includes at least one of a heating module 800 and a ventilation module 900. The heating module 800 provides a warm seat 10 experience, especially in cold environments, which can enhance comfort. The ventilation module 900 provides air circulation in hot weather or during long rides, helping to regulate the surface temperature of the seat 10 and reduce occupant discomfort caused by high temperatures. By combining the heating module 800 and the ventilation module 900, the seat 10 can dynamically adjust the temperature of the seat 10 according to different environmental conditions and occupant needs, further enhancing the comfort and user experience of the seat 10.

[0177] In some examples, the heating module 800 and ventilation module 900 can provide various functional supports based on different application requirements and environmental conditions. The heating module 800 may include electric heating wires, heat-conductive materials, or other heating elements, and is positioned in the seat cushion and backrest areas of the seat 10. It uses electricity to heat the seat 10, providing a warm experience. The temperature of the seat 10 can be adjusted using temperature control switches, temperature sensors, and other means to adapt to cold weather or environments, enhancing passenger comfort.

[0178] In some examples, the ventilation module 900 may include a built-in small fan, air circulation ducts, and an air filtration system connected to the seat 10 structure. The fan directs airflow, helping to dissipate heat and maintain a dry feel. The ventilation module 900 is suitable for hot climates, reducing the surface temperature of the seat 10 by enhancing air flow, alleviating moisture and discomfort caused by prolonged sitting. The two can be used independently or in combination, automatically adjusting to the external environment and personal needs to ensure a comfortable seat 10 experience in various climates.
