TECHNICAL FIELD

[0001] The present application relates to the technical field of automotive accessories, in particular to a super-thin intelligent zero-gravity seat for top new energy vehicles and aviation. BACKGROUND

[0002] The existing zero-gravity seats mainly rely on angle adjustment mechanisms to adjust the angle between the cushion and the backrest to form a relaxed posture with the legs raised; the comfort and the wrapping effect are generally achieved by thick sponge fillers combined with skin layers in an integrated or zoned manner.

[0003] Such traditional structures have the following limitations: first, in order to achieve sufficient static lateral support, the side wings are usually designed to be more protruding, which will continuously press the body on both sides in the normal riding state without lateral inclination, affecting the comfort; Secondly, when the vehicle is dynamically running, such as turning or changing lanes, the fixed side wing structure cannot actively enhance the support force according to the real-time lateral force, which has the potential safety hazard of support lag or deficiency. SUMMARY

[0004] Therefore, the present application aims to solve the above problems.

[0005] To achieve the above technical purposes, the present application provides a super-thin intelligent zero-gravity seat for top new energy vehicles and aviation, which comprises a seat framework and a wrapping assembly, the seat framework comprises a fixed seat, a cushion framework and a backrest framework, and the wrapping assembly covers the outer sides of the cushion framework and the backrest framework. Each side of the backrest framework is provided with a set of linkage support mechanisms, and the linkage support mechanisms comprise a side wing support frame, a connecting frame and a second support spring. The end of the side wing support frame towards the inner side of the backrest framework is provided with an inwardly bent pressure-touching part, one end of the pressure-touching part is hinged to the backrest framework, the other end is fixedly connected to the end of the connecting frame, and the other end of the connecting frame is fixedly connected to the end of the second support spring.

[0008] Preferably, the STF core body is composed of a shear thickening liquid impregnated in a porous flexible foam substrate; and the flexible packaging layer is a thermoplastic polyurethane film.

[0009] Preferably, the ACF shock absorption layer of the side wing functional area has a thickness smaller than that of the ACF shock absorption layer of the middle supporting area.

[0010] Preferably, the three-dimensional spacer fabric ventilation layer is formed by compounding the surface fabric, the inner fabric and the warp-knitted spacer yarns connecting the two by means of a hot melt adhesive film, and vertical air channels are formed inside.

[0011] Preferably, the ACF shock absorption layer is a high-damping shock absorption foam layer attached to the surface of the seat cushion framework, the backrest framework and the side wing support frame.

[0012] Preferably, the second support spring is a flat S-shaped spring, and in a natural state, the elastic force of the second support spring keeps the side wing support frame at a first embracing angle through the connecting frame; when the connecting frame is pushed by a lateral force, the side wing support frame is driven to rotate to a second embracing angle smaller than the first embracing angle.

The addition of the STF support layer in the side wing functional area makes it shear thickening and hardening under dynamic impact, thereby providing dynamic material support in real time in response to the impact strength while providing basic support through mechanical linkage, and the dual response mechanism of the mechanical and material cooperatively realizes more timely and more firm lateral posture constraint, improving the dynamic safety; 3. The adoption of the three-dimensional spacer fabric ventilation layer as the main supporting surface, combined with the ultra-thin ACF shock absorption layer and the STF support layer which hardens only under dynamic conditions, replaces most of the traditional thick sponge, and this structure significantly reduces the total thickness of the cladding assembly, realizes the ultra-thin design of the whole seat, and realizes efficient passive convection heat dissipation through the vertical air channels of the spacer fabric, improving the thermal comfort of the ride.

[0019] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0020] For examples, see Figures 1-12 As shown, an ultra-thin intelligent zero-gravity seat for top-tier new energy vehicles and aviation includes a seat frame 10 and a covering component 20 covering the outside of the seat frame 10. The seat frame 10 includes a fixed seat 11, a seat cushion frame 12, and a backrest frame 13. Both the seat cushion frame 12 and the backrest frame 13 are hinged to the fixed seat 11 through an angle adjuster, so that the backrest frame 13 can be reclined backward, while the front end of the seat cushion frame 12 can be raised upward, together forming a zero-gravity posture.

[0021] An adjustable seat is a standard component widely used in this field. Its core function is to allow relative rotation between two connected components within a certain angle range and to reliably lock at any angle. In this invention, a mechanical type, such as a worm gear self-locking type, pneumatic type, or electric type, can be used. Taking a commonly used electric adjustable seat as an example, it typically includes a small motor, a set of reduction gears, and a clutch mechanism with a self-locking function. After receiving a signal from the seat control unit, the motor drives the gears, thereby causing the seat cushion frame 12 or backrest frame 13 to rotate around the hinge axis. When the preset angle is reached or the power supply is stopped, the clutch mechanism locks, fixing the frame in that position. Through the action of the adjustable seat, the seat can be adjusted from a normal sitting posture to a zero-gravity posture. The specific structure of the adjustable seat is a known and disclosed technology, and its internal mechanical details will not be described in detail here.

[0022] Specifically, the fixed seat 11 consists of side plates on both sides and a first connecting rod 111 connecting the two side plates, forming a sturdy "U"-shaped or box-shaped frame structure. The bottom of the fixed seat 11 is installed on the chassis of a vehicle or aircraft via a sliding rail mechanism to achieve the front and rear adjustment of the seat.

[0023] The seat cushion frame 12 is a component that supports the occupant's buttocks and thighs. Its front end is supported by a first connecting rod 111, and its rear end is connected to the side plate of the fixed seat 11 through an angle adjuster. The seat cushion frame 12 includes a seat cushion side plate 121, a second connecting rod 122, and a first support spring 123. There are two seat cushion side plates 121, one on the left and one on the right, which are the longitudinal load-bearing bodies of the seat cushion frame 12. The two seat cushion side plates 121 are supported by two second connecting rods 122 distributed at the front and rear ends of the seat cushion side plates 121. The second connecting rods 122 are transverse reinforcements of the seat cushion frame 12, ensuring that the two seat cushion side plates 121 deform together when bearing load. Furthermore, the first support spring 123 is a flat "S"-shaped elastic metal component, with its two ends fixed to two second connecting rods 122 respectively. The purpose is to provide elastic support for the middle of the seat cushion area, forming an ergonomic support surface together with the covering component 20. When the seat is adjusted to a zero-gravity posture, it helps to support the additional load caused by the lifting of the front of the seat cushion, preventing the middle of the seat cushion from collapsing excessively.

[0024] The backrest frame 13 is a component that supports the back and waist of the occupant. Its lower end is connected to the side plate of the fixed base 11 through an angle adjuster. The backrest frame 13 includes a backrest side plate 131, a third connecting rod 132, and a U-shaped rod 133. There are two backrest side plates 131, one on the left and one on the right, which are the longitudinal load-bearing bodies of the backrest frame 13. The two backrest side plates 131 are connected by the third connecting rod 132 and the U-shaped rod 133. The third connecting rod 132 is a key lateral reinforcement. The two ends of the U-shaped rod 133 are respectively fixed to the top of the two backrest side plates 131, forming the upper frame of the backrest frame 13, which enhances the rigidity of the top structure and provides support for the shoulder area.

[0025] In order to achieve adaptive adjustment of lateral support, a set of linkage support mechanism is provided on each of the left and right sides of the backrest frame 13. The linkage support mechanism includes a side wing support frame 14, a connecting frame 141 and a second support spring 15. The side wing support frame 14 is connected to both sides of the second support spring 15 through the connecting frame 141. Specifically, the side wing support frame 14 has an inwardly bent pressing part at one end facing the inside of the backrest frame 13. One end of the pressing part is hinged to the backrest side plate 131, allowing it to rotate around the hinge point within a certain angle range. The other end of the pressing part is fixedly connected to the end of the connecting frame 141, which is a rigid connecting rod. The other end of the connecting frame 141 is fixedly connected to the end of the second support spring 15.

[0026] The second support spring 15 has the same structure as the first support spring 123. In the natural state, i.e., when the occupant is not tilting to the side, the elastic force of the second support spring 15 acts on the pressing part of the side wing support frame 14 through the connecting frame 141, so that the side wing support frame 14 is maintained in a large angle of unfolding position. At this time, the angle between the side wing support frame 14 and the main plane of the backrest is large, and the pressing part at the front end of the side wing support frame 14 is far away from the occupant's body, so that the covering component 20 is relatively flat overall, avoiding the continuous pressure on the occupant's ribs by traditional fixed high side wings; providing the occupant with a loose wrapping feeling; when the vehicle begins to turn, the occupant's body tilts to the side, squeezing the side wing area of ​​the seat. The pressure is transmitted to the connecting frame 141 through the covering component 20, pushing the connecting frame 141 to move and drive the side wing support frame 14 to rotate inward around the hinge axis, reducing the wrapping angle and providing enhanced rigid support from a mechanical structure perspective.

[0027] The covering component 20 covers the outer side of the seat frame 10. The covering component 20 is divided into a central support area and a side wing functional area according to the different functions of the area. The covering component 20 of the side wing functional area has an additional STF support layer 21 compared with the covering component 20 of the central support area.

[0028] For details, please refer to Figure 8As shown, the central support area covering component 20 includes an ACF shock-absorbing layer 201, a three-dimensional spacer fabric ventilation layer 202, and an outer covering surface 203 that are sequentially attached from the inside to the outside. For further details, please refer to [link / reference]. Figure 9 As shown, the wing functional area covering assembly 20 includes, from the inside out, an ACF shock-absorbing layer 201, an STF support layer 21, a three-dimensional spacer fabric ventilation layer 202, and an outer covering surface 203.

[0029] The ACF damping layer 201 is the innermost layer. ACF here refers to high-damping shock-absorbing foam. This layer is directly attached to the surface of the seat frame 12, backrest frame 13 and side wing support frame 14. The ACF damping layer 201 is made of modified polyurethane foam with a high damping loss factor. Its function is to convert the high-frequency fine vibration mechanical energy transmitted from the seat frame 10 in the range of 10-100Hz into heat energy through the friction of the polymer chains inside the material and dissipate it, thereby effectively attenuating the vibration transmitted to the occupant's body.

[0030] The three-dimensional spacer fabric ventilation layer 202 directly covers the ACF shock-absorbing layer 201 in the central support area and covers the STF support layer 21 in the side functional areas. The three-dimensional spacer fabric ventilation layer 202 is composed of an outer fabric, an inner fabric, and warp-knitted spacer yarns connecting the two through a hot melt adhesive web, forming a three-dimensional structure with a large number of vertically penetrating air channels. The three-dimensional spacer fabric ventilation layer 202 utilizes its elastic structure and vertical air channels to achieve ergonomic pressure distribution and achieve passive convection heat dissipation through airflow caused by changes in sitting posture.

[0031] The outermost layer of the covering component 20 is the outer covering surface 203, which is made of leather or high-performance textile fabric and serves both decorative and protective functions.

[0032] Since the three-dimensional spacer fabric ventilation layer 202 serves as the main support surface, it provides elastic support and heat dissipation while being thinner and lighter than traditional thick sponges. Furthermore, the STF support layer 21 only becomes rigid under dynamic conditions, allowing its static thickness to be controlled. As a result, the total thickness of the entire covering assembly 20 is significantly lower than the thickness of the sponge filling layer required in traditional seats to achieve the same comfort and support performance. The specific thicknesses of the ACF shock-absorbing layer 201, the STF support layer 21, the three-dimensional spacer fabric ventilation layer 202, and the outer covering surface 203 are determined by those skilled in the art based on actual needs and are not specifically limited here.

[0033] Furthermore, in the side functional area, an STF support layer 21 is provided above the ACF filtering layer 201; the STF support layer 21 is composed of an inner STF core 211 and an outer flexible encapsulation layer 212; the STF core 211 is formed by fully impregnating an open-cell flexible foam substrate with a shear thickening fluid; the shear thickening fluid is STF, which is a non-Newtonian fluid made by dispersing nano-sized rigid particles in a polymer base liquid. It is in a fluid state at low shear rates and thickens and hardens instantaneously at high shear rates; the flexible encapsulation layer 212 is a thermoplastic polyurethane film, which completely wraps the STF core 211 through a sealing process to prevent liquid leakage; The purpose is to provide immediate and effective lateral material support by adding an STF support layer 21 to the side wing functional area. When the vehicle's dynamic movement causes the occupant's body to quickly compress the side wing, the shear thickening fluid inside the layer hardens instantly due to the high shear rate, while in a natural state, the shear thickening fluid in the STF support layer 21 is in a liquid state, providing soft support for the occupant and ensuring comfort.

[0034] Working principle: In normal riding conditions, the second support spring 15 of the linkage support mechanism keeps the side wing support frame 14 extended, the side wing area is generally flat, and the STF support layer 21 is in a soft state, providing a comfortable wrap. When the vehicle turns, causing the occupants to lean to the side, their bodies compress the side wing functional area. The pressure is transmitted to the connecting frame 141 through the covering component 20, which pushes the connecting frame 141 to move and drive the side wing support frame 14 to rotate inward around the hinge axis, reducing the circumferential angle and providing enhanced rigid support from the mechanical structure. At the same time, the rapid compression of the body causes the shear thickening fluid in the STF support layer 21 to undergo high shear rate and harden instantly, providing additional dynamic support from the material level. When the dynamic driving ends and the lateral force disappears, the second support spring 15 pushes the mechanism to reset, and the STF support layer 21 also returns to a soft state. Throughout the process, the ACF vibration filtering layer 201 continuously filters vibration, and the three-dimensional spaced fabric ventilation layer 202 continuously dissipates heat.

[0035] The exemplary implementation of the solution proposed in this disclosure has been described in detail above with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
