Description

Technical Field

[0001] This invention relates to the field of vehicle manufacturing technology, and more particularly to a seat assembly and a vehicle having the seat assembly. Background Technology

[0002] Vehicle seats come in a wide variety of types, including zero-gravity seats, airline seats, ABTS (Automatic Beam Transit System) seats, and non-ABTS seats. As an important functional component of the vehicle, vehicle seats serve to support passengers, improve the riding experience, and enhance the brand value of the car. Therefore, the functional options available for seats will become a key factor influencing the evaluation of drivers and passengers. Furthermore, with the gradual increase in in-vehicle entertainment facilities, such as in-car TVs and projectors, higher demands are being placed on the riding experience of vehicle seats.

[0003] In related technologies, ordinary ABTS seats do not have a rotation function and have limited functionality. Summary of the Invention

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more. In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] Unless otherwise specified, the front-back direction in this application refers to the longitudinal direction of the vehicle, i.e., the X direction; the left-right direction refers to the lateral direction of the vehicle, i.e., the Y direction; and the up-down direction refers to the vertical direction of the vehicle, i.e., the Z direction.

[0024] The following is for reference. Figures 1-16 A seat assembly 100 according to an embodiment of the present invention is described. The seat assembly 100 has a rotation function and a fore-and-aft sliding function, and has multiple functions, which can effectively improve the comfort of passengers.

[0025] like Figures 1-16 As shown, a seat assembly 100 according to an embodiment of the present invention includes: a seat frame 1, a rotating structure 2, a mounting bracket 3, and a longitudinal slide rail structure 4.

[0026] First, it should be noted that the seat assembly 100 of the present invention can be the second row seat of a vehicle, and the seat type can be an ABTS seat (All-Belt-To-Seat), or other types of seats, such as zero-gravity seats, aviation seats, etc.

[0027] The seat frame 1 is the core support structure of the seat assembly 100, directly supporting the human body and bearing its weight. The seat frame 1 includes a backrest frame 12 and a seat cushion frame 11. The backrest frame 12 supports the seat back and primarily bears the pressure on the occupant's back and head, protecting the occupant from injury in a collision. The seat cushion frame 11 supports the seat cushion and needs to provide sufficient support to ensure passenger comfort while distributing body pressure. The backrest frame 12 and seat cushion frame 11 are rotatably connected by an adjustment mechanism, allowing the backrest frame 12 to rotate relative to the seat cushion frame 11 in the vehicle's fore-and-aft direction to adjust its height. This allows the seat to adapt to different occupant needs, improving seating comfort.

[0028] The rotating structure 2 is used to adjust the direction of the seat frame 1, allowing the seat frame 1 to rotate arbitrarily in the horizontal direction, that is, to rotate left and right around the vertical axis. The rotating structure 2 includes a rotating disk assembly 21 and a fixed disk assembly 22. The rotating disk assembly 21 is a movable component that can rotate, while the fixed disk assembly 22 is a fixed component that is stationary. The seat frame 1 is connected above the rotating disk assembly 21, so that the seat frame 1 and the rotating disk assembly 21 are connected as a whole structure. The seat frame 1 and the rotating disk assembly 21 are relatively fixed and can be connected by means of screwing, riveting, snap-fitting, welding, etc., which can be flexibly set. The rotating disk assembly 21 is rotatably mounted on the fixed disk assembly 22 so that the seat frame 1 can rotate relative to the fixed disk assembly 22. That is, the rotating disk assembly 21 is mounted on the fixed disk assembly 22 to provide a mounting point for the rotating disk assembly 21 and support the rotating disk assembly 21. The rotating disk assembly 21 can rotate relative to the fixed disk assembly 22, and when the rotating disk assembly 21 rotates, it can drive the seat frame 1 to rotate together relative to the fixed disk assembly 22, so that the seat frame 1 can rotate at any angle inside the vehicle to adjust the direction of the seat frame 1 so that the occupant can face any direction.

[0029] Therefore, by setting the rotating structure 2 so that the seat assembly 100 has a rotating function, the rotation of the seat frame 1 can, firstly, free up more passage space, making it easier to load large items and facilitate the entry and exit of rear passengers, and can also utilize the aisle between the second row of seats to improve riding comfort; secondly, it facilitates face-to-face communication among passengers, realizing more possible scenarios.

[0030] Furthermore, the seat assembly 100 also includes a mounting bracket 3 and a longitudinal slide rail structure 4. The longitudinal slide rail structure 4 includes a longitudinal support rail 41 and a longitudinal sliding rail 42. The longitudinal support rail 41 is connected to the rear floor, and the longitudinal sliding rail 42 is slidably mounted on the longitudinal support rail 41. The fixed plate assembly 22 is connected to the longitudinal sliding rail 42 via the mounting bracket 3 so that the seat frame 1 is slidable in the longitudinal direction relative to the longitudinal support rail 41.

[0031] Specifically, the mounting bracket 3 supports the rotating structure 2 and seamlessly connects the rotating structure 2 and the longitudinal slide rail structure 4. The longitudinal slide rail structure 4 is used to adjust the fore-and-aft position of the seat frame 1, allowing the seat frame 1 to slide along the fore-and-aft direction of the vehicle to the desired adjustment position. The longitudinal slide rail structure 4 includes a longitudinal support rail 41 and a longitudinal sliding rail 42. The longitudinal support rail 41 is a fixed component connected to the rear floor and can be connected by screwing, welding, riveting, snap-fitting, etc., thus stably connecting the longitudinal support rail 41 to the rear floor to provide a stable mounting support point for the seat assembly 100, ensuring that the entire seat assembly 100 is firmly installed on the rear floor and preventing it from shaking. Both the longitudinal support rail 41 and the longitudinal sliding rail 42 can extend along the fore-and-aft direction of the vehicle, and the longitudinal length of the longitudinal sliding rail 42 can be set to be less than the longitudinal length of the longitudinal support rail 41. In this way, after the longitudinal sliding rail 42 is installed on the longitudinal support rail 41, the longitudinal sliding rail 42 can slide back and forth along the longitudinal support rail 41. The upper side of the mounting bracket 3 is connected to the fixed plate assembly 22, and the lower side of the mounting bracket 3 is connected to the longitudinal sliding guide rail 42. Thus, the fixed plate assembly 22 is connected to the longitudinal sliding guide rail 42 through the mounting bracket 3. The fixed plate assembly 22, the mounting bracket 3, and the longitudinal sliding guide rail 42 are connected to form a relatively fixed integral structure. When the longitudinal sliding guide rail 42 slides back and forth along the longitudinal support guide rail 41, the longitudinal sliding guide rail 42 can drive the mounting bracket 3, the rotating structure 2, and the seat frame 1 to slide together relative to the longitudinal support guide rail 41 in the front and back direction, thereby realizing the flexible adjustment of the front and back position of the seat frame 1.

[0032] Therefore, by setting the longitudinal sliding rail structure 4 so that the seat assembly 100 has the function of sliding forward and backward, the space of the third row or trunk of the vehicle can be increased by adjusting the position of the seat frame 1 when the second row of seats is not in use, as well as the space of the second row passage, thereby improving the user experience.

[0033] Understandably, the length of the longitudinal support rail 41 limits the maximum position at which the seat frame 1 can slide forward and backward. The maximum position at which the seat frame 1 can move forward or backward can be adjusted by adjusting the length of the longitudinal support rail 41.

[0034] By connecting the fixed plate assembly 22 to the longitudinal sliding guide rail 42 through the mounting bracket 3, the structural strength of the longitudinal sliding guide rail 42 can be enhanced. This allows the reinforced longitudinal sliding guide rail 42 to stably support the seat frame 1 and the rotating structure 2, bear the weight of the seat frame 1 and the rotating structure 2, and reduce the deformation of the longitudinal sliding guide rail 42. This enables the longitudinal sliding guide rail 42 to more stably drive the rotating structure 2 and the seat frame 1 to slide back and forth together. In addition, the mounting bracket 3 can provide a connection point for the fixed plate assembly 22 and the longitudinal sliding guide rail 42, which can smoothly transition and connect the rotating structure 2 and the longitudinal sliding rail structure 4, avoiding the inability of the rotating structure 2 and the longitudinal sliding rail structure 4 to be directly connected, which would prevent the seat assembly 100 from being assembled as a whole.

[0035] According to an embodiment of the present invention, the seat assembly 100, by providing a rotating structure 2, enables the seat assembly 100 to rotate, allowing full utilization of the vehicle's interior space and improving passenger comfort through the rotation of the seat frame 1. By providing a longitudinal slide rail structure 4, the seat assembly 100 enables the seat assembly 100 to slide forward and backward, thereby increasing the space of the third row or trunk, as well as the space of the second row passage, when the second row seats are not in use, by adjusting the forward and backward position of the seat frame 1, thus improving the user experience. By providing a mounting bracket 3 to connect the rotating structure 2 and the longitudinal slide rail structure 4, the reinforced longitudinal slide rail 42 can stably support the seat frame 1 and the rotating structure 2, bear the weight of the seat frame 1 and the rotating structure 2, reduce the deformation of the longitudinal slide rail 42, and enable the longitudinal slide rail 42 to more stably drive the rotating structure 2 and the seat frame 1 to slide longitudinally together. The mounting bracket 3 can provide a connection point for the fixed plate assembly 22 and the longitudinal slide rail 42, allowing for a smooth transition connection between the rotating structure 2 and the longitudinal slide rail structure 4, avoiding the inability to directly connect the rotating structure 2 and the longitudinal slide rail structure 4, which would prevent the seat assembly 100 from being assembled as a whole.

[0036] In some embodiments, such as Figure 8 and Figure 9 As shown, the mounting bracket 3 includes two longitudinal beams 31 and two transverse beams 32. The two longitudinal beams 31 extend longitudinally (front-back direction) and are spaced apart laterally by a certain distance. The two transverse beams 32 extend laterally (left-right direction) and are spaced apart longitudinally by a certain distance. The left end of the two transverse beams 32 is connected to the left longitudinal beam 31, and the right end of the two transverse beams 32 is connected to the right longitudinal beam 31, so that the two transverse beams 32 are connected between the two longitudinal beams 31. Thus, the two longitudinal beams 31 and the two transverse beams 32 together form a stable rectangular frame structure with good stability, high resistance to deformation, and high load-bearing capacity, which can stably support the rotating structure 2 and the seat frame 1.

[0037] Furthermore, the fixed plate assembly 22 is connected to the support crossbeam 32 and the support longitudinal beam 31 respectively. The bottom of the support longitudinal beam 31 is provided with at least one first connecting part 3121, which is connected to the longitudinal sliding guide rail 42.

[0038] In other words, the fixed plate assembly 22 is connected to both the left and right longitudinal beams 31 and the front and rear crossbeams 32. This provides more installation support points for the fixed plate assembly 22 through the left and right longitudinal beams 31 and the front and rear crossbeams 32, ensuring the stable installation of the fixed plate assembly 22, improving the installation stability and reliability of the rotating structure 2, and preventing the longitudinal slide rail structure 4 from being unable to effectively support the fixed plate assembly 22, which would lead to the unstable installation of the rotating structure 2 and the longitudinal slide rail structure 4 bearing excessive load.

[0039] The bottom of the bracket longitudinal beam 31 may be provided with one, two, three or more first connecting parts 3121. The first connecting parts 3121 are used to connect the longitudinal sliding guide rail 42. The first connecting parts 3121 provide mounting points for the longitudinal sliding guide rail 42, so that the mounting bracket 3 and the longitudinal sliding guide rail 42 are stably and reliably connected.

[0040] Thus, the mounting bracket 3 enables a smooth connection between the fixed disk assembly 22 and the longitudinal sliding guide rail 42, that is, a smooth connection between the rotating disk 211 and the longitudinal slide rail structure 4.

[0041] In some embodiments, such as Figure 11 As shown, the fixed plate assembly 22 includes a fixed plate 221 and a fixed bracket 222. The fixed plate 221 can be configured as a disc, and the fixed bracket 222 can be configured as an annular shape. The inner diameter of the fixed bracket 222 can be configured to match the outer diameter of the fixed plate 221, so that the fixed bracket 222 can be connected to the outer periphery of the fixed plate 221 in the inward and outward direction (from the center of the fixed plate 221 outward). This achieves the connection between the fixed bracket 222 and the fixed plate 221, and the fixed bracket 222 is distributed around the fixed plate 221. In actual design, the fixed bracket 222 and the fixed plate 221 can be fixedly connected by screwing, riveting, snap-fitting, or other connection methods, which can be flexibly set. The rotating disk assembly 21 is rotatably engaged with the fixed disk 221, allowing the rotating disk assembly 21 to rotate relative to the fixed disk 221 and the fixed bracket 222. The rotating disk assembly 21 and the fixed disk 221 can achieve the rotatable engagement through axial bearings, shafts, etc. For example, the seat ring of the thrust roller bearing can be connected to the fixed disk 221, and the shaft ring of the thrust roller bearing can be connected to the rotating disk assembly 21. By the rolling elements rolling between the seat ring and the shaft ring, the shaft ring can achieve low-friction rotation relative to the seat ring, thus realizing the rotatable engagement between the rotating disk assembly 21 and the fixed disk 221 and reducing the friction between the rotating disk assembly 21 and the fixed disk 221.

[0042] Furthermore, both support beams 32 and both support longitudinal beams 31 are provided with fixed connection parts 321. Multiple fixed connection parts 321 are distributed around the fixed plate 221, and multiple fixed connection parts 321 are detachably connected to the fixed support 222 through fixed connectors 5.

[0043] Specifically, such as Figure 9 As shown, the front and rear support crossbeams 32 are provided with fixed connection parts 321, and the left and right support longitudinal beams 31 are also provided with fixed connection parts 321, that is, multiple fixed connection parts 321 are provided. The fixed disk 221 is constructed in the shape of a disk, and the multiple fixed connection parts 321 are distributed at intervals along the circumference of the fixed disk 221. That is, the front and rear support crossbeams 32 and the left and right support longitudinal beams 31 are distributed in the peripheral bottom area of ​​the fixed disk 221. The multiple fixed connection parts 321 can be detachably connected to the fixed support 222 through fixed connectors 5, that is, each fixed connection part 321 is detachably connected to the fixed support 222 through a corresponding fixed connector 5, so that the fixed support 222 and the mounting bracket 3 are connected at multiple positions in the circumference of the fixed disk 221, improving the connection stability and reliability of the fixed support 222 and the mounting bracket 3, thereby enabling the rotating disk assembly 21 to rotate stably.

[0044] In actual design, the fixing connector 5 can be set as a bolt, screw or other threaded connector to realize the threaded connection between the fixing bracket 222 and the mounting bracket 3. The fixing connector 5 can also be set as a pin to realize the plug connection between the fixing bracket 222 and the mounting bracket 3. It can also be set as a rivet or the like to realize the non-removable connection.

[0045] In a specific embodiment, such as Figures 8-11 As shown, the fixed connection part 321 can be constructed as a fixed connection hole. The inner peripheral wall of the fixed connection hole can have an internal thread. Multiple fixed connection holes are distributed along the circumference of the fixed plate 221. Multiple first mating holes can be correspondingly provided on the fixed bracket 222. The positions of the multiple fixed connection holes and the multiple first mating holes are corresponding. The fixed connection member 5 is constructed as a connecting bolt. The connecting bolt passes through the first mating hole and the fixed connection hole from top to bottom to realize the fixed connection between the fixed plate assembly 22 and the mounting bracket 3. A connecting nut can also be provided at the lower end of the connecting bolt for tightening to prevent the connection from loosening.

[0046] In some embodiments, the rotating disk assembly 21 includes a rotating disk 211 and a rotating bracket 212. The rotating disk 211 is rotatably engaged with a fixed disk 221. The rotating bracket 212 is connected to the rotating disk 211 and extends upward relative to the rotating disk 211 in at least a portion. At least a portion of the rotating bracket 212 is detachably connected to the seat frame 1. One of the rotating bracket 212 and the fixed bracket 222 is provided with a limiting flange 2121 and the other is provided with a mating flange 22221. The limiting flange 2121 and the mating flange 22221 are circumferentially movable relative to each other and radially limitedly engaged.

[0047] Specifically, the rotating disk 211 is disc-shaped and is adapted to the fixed disk 221. The rotating disk 211 and the fixed disk 221 can be rotated relative to the fixed disk 221 through bearings, shafts, etc. The rotating disk 211 can rotate relative to the fixed disk 221. The rotating bracket 212 can be connected above the fixed disk 221 so that the rotating bracket 212 and the rotating disk 211 are connected as a whole structure. The rotating bracket 212 is used to connect the seat frame 1. At least part of the rotating bracket 212 can extend upward relative to the rotating disk 211 so that at least part of the rotating bracket 212 is directly opposite the seat frame 1. Thus, at least part of the rotating bracket 212 and the seat frame 1 can be detachably connected by snap-fit, screw-fit, plug-in, or other connection methods. Thus, the rotating disk assembly 21 and the seat frame 1 are fixedly connected by the rotating bracket 212. When the rotating disk 211 rotates, the rotating disk 211 can drive the rotating bracket 212 and the seat frame 1 to rotate together.

[0048] Among them, such as Figure 12 As shown, a limiting flange 2121 can be provided on the rotating bracket 212, and a mating flange 22221 can be provided on the fixed bracket 222. The limiting flange 2121 and the mating flange 22221 can move relative to each other in the circumferential direction, so that the rotating bracket 212 can rotate horizontally relative to the fixed bracket 222. The surface of the limiting flange 2121 and the surface of the mating flange 22221 can press against each other radially along the rotating bracket 212 or the fixed bracket 222, so as to achieve radial limiting engagement between the limiting flange 2121 and the mating flange 22221, preventing the rotating bracket 212 from tilting relative to the fixed bracket 222, which would cause the seat to tilt.

[0049] In practical design, such as Figure 12As shown, the rotating bracket 212 is provided with a limiting flange 2121, and the fixed bracket 222 is provided with a mating flange 22221. At least a portion of the limiting flange 2121 extends downward and forms an upwardly open first limiting groove 21211. At least a portion of the mating flange 22221 extends upward and forms a downwardly open second limiting groove 22221a. The second limiting groove 22221a is located above the first limiting groove 21211, and the inner wall of the second limiting groove 22221a is radially aligned with the inner wall of the first limiting groove 21211. Thus, when the rotating bracket 212 is radially offset relative to the fixed bracket 222, the inner wall of the second limiting groove 22221a and the inner wall of the first limiting groove 21211 can be tightly pressed radially to limit the radial offset of the rotating bracket 212.

[0050] In some embodiments, the fixed bracket 222 includes a bracket main board portion 2221 and a bracket flange portion 2222. The bracket main board portion 2221 is snapped into connection with the fixed disk 221, and the bracket main board portion 2221 is connected to the fixed connection portion 321 through a fixed connector 5. The bracket flange portion 2222 is connected to the outer periphery of the bracket main board portion 2221 and is folded upward. At least one of the bracket crossbeam 32 and the bracket longitudinal beam 31 is provided with a limiting abutment surface 322. At least a portion of the bracket flange portion 2222 is radially limited and abutted with the limiting abutment surface 322 along the fixed disk 221.

[0051] Specifically, such as Figure 15 As shown, a buckle or protrusion can be provided in one of the bracket main board 2221 and the fixing plate 221, and a slot can be provided in the other. The buckle or protrusion engages with the slot, thus connecting the bracket main board 2221 and the fixing plate 221, facilitating the installation and removal of the fixing bracket 222 and the fixing plate 221. Figure 14 As shown, the main support portion 2221 is located above the two longitudinal beams 31 and the two transverse beams 32 of the support, so that the fixed connection portion 321 is vertically aligned with the main support portion 2221. The fixed connection member 5 can pass through the main support portion 2221 and the fixed connection portion 321 in the vertical direction, so that the main support portion 2221 and the fixed connection portion 321 are connected by the fixed connection member 5, thereby realizing the fixed connection between the fixed bracket 222 and the mounting bracket 3.

[0052] Among them, such as Figure 13 and 14 As shown, the bracket flange 2222 is connected to the outer periphery of the bracket main plate 2221 and folded upwards. The bracket flange 2222 can enhance the structural strength of the fixed bracket 222, such as... Figure 8As shown, a limiting and pressing surface 322 can be provided on the crossbeam 32 of the support, or a limiting and pressing surface 322 can be provided on the longitudinal beam 31 of the support, or a limiting and pressing surface 322 can be provided on both the crossbeam 32 and the longitudinal beam 31 of the support. Figure 8 The diagram shows that limiting abutment surfaces 322 are provided at the left and right ends of the front and rear support beams 32. The limiting abutment surfaces 322 are adapted to the shape of the support flange 2222. At least part of the outer surface of the support flange 2222 can press against the surface of the limiting abutment surface 322 along the radial direction of the fixing plate 221, so as to realize that at least part of the support flange 2222 and the limiting abutment surface 322 are in a radial limiting abutment fit along the fixing plate 221, thereby making the relative position of the fixed support 222 and the mounting support 3 more stable and preventing the fixed support 222 from radially shifting.

[0053] In some embodiments, each support longitudinal beam 31 is provided with a plurality of fixed connection parts 321, and the plurality of fixed connection parts 321 are spaced apart along the length direction of the support longitudinal beam 31.

[0054] In other words, each of the left and right support longitudinal beams 31 is provided with two, three, four or more fixed connection parts 321. The multiple fixed connection parts 321 are distributed at a certain distance along the length direction of the support longitudinal beam 31, which is the front and rear direction of the vehicle. In this way, interference between the multiple fixed connection parts 321 and insufficient local structural strength can be avoided. Moreover, the support longitudinal beam 31 and the fixed bracket 222 can be connected at multiple positions through multiple fixed connectors 5, thereby improving the connection stability and reliability between the support longitudinal beam 31 and the mounting bracket 3.

[0055] In a specific embodiment, such as Figure 8 As shown, both the left and right support longitudinal beams 31 are provided with four fixed connection parts 321. Two fixed connection parts 321 form a group. One group of fixed connection parts 321 is located at the front of the support longitudinal beam 31, and the other group of fixed connection parts 321 is located at the rear of the support longitudinal beam 31. This allows the support longitudinal beam 31 to be stably connected to the fixed bracket 222. Of course, fixed connection parts 321 can also be provided in the middle of the support longitudinal beam 31 to further improve the connection stability and reliability. If the fixed connector 5 at one of the fixed connection parts 321 fails, the fixed connectors 5 at the other fixed connection parts 321 can still work normally, ensuring the connection between the support longitudinal beam 31 and the mounting bracket 3 and preventing the entire seat assembly 100 from becoming loose.

[0056] In other embodiments, each support beam 32 is provided with at least one reinforcing boss 323, the reinforcing boss 323 is configured to protrude upward relative to the upper surface of the support beam 32 to support the bottom surface of the fixed bracket 222, and the reinforcing boss 323 is provided with a fixed connection portion 321.

[0057] In other words, each of the front and rear support beams 32 is provided with one, two or more reinforcing protrusions 323. The reinforcing protrusions 323 are constructed to protrude upward relative to the upper surface of the support beam 32, so that the upper surface of the reinforcing protrusions 323 fits against the bottom surface of the fixed bracket 222. Thus, the reinforcing protrusions 323 support the bottom surface of the fixed bracket 222. Therefore, by reinforcing the protrusions 323, the local structural strength of the mounting bracket 3 can be improved, and the connection area between the fixed bracket 222 and the support beam 32 can be increased, so that the support beam 32 can support the fixed bracket 222 more stably.

[0058] Among them, the reinforcing boss 323 is provided with a fixed connection part 321, that is, the fixed connection part 321 is provided at the reinforcing boss 323, which can improve the structural strength of the surrounding area of ​​the fixed connector 5, prevent local stress concentration from causing deformation or cracking, and the support beam 32 cannot effectively support the fixed support 222.

[0059] In a specific embodiment, such as Figure 8 As shown, both the front support beam 32 and the rear support beam 32 are provided with two reinforcing protrusions 323. Taking the front support beam 32 as an example, one reinforcing protrusion 323 is located on the left side of the support beam 32, and the other reinforcing protrusion 323 is located on the right side of the support beam 32. The reinforcing protrusion 323 is constructed to protrude upward relative to the upper surface of the support beam 32. The fixed bracket 222 is provided with two spaced-apart cooperating reinforcing protrusions 2223. The cooperating reinforcing protrusions 2223 are constructed to protrude downward relative to the upper surface of the fixed bracket 222. The upper surfaces of the two reinforcing protrusions 323 abut and fit against the bottom surfaces of the corresponding cooperating reinforcing protrusions 2223. The fixed connector 5 is adapted to be sequentially inserted from top to bottom through the cooperating reinforcing protrusions 2223 and the fixed connector 321 to realize the fixed connection between the fixed bracket 222 and the support beam 32. Thus, the support beam 32 can be stably connected to the fixed bracket 222 through the two reinforcing protrusions 323. Among them, the mating reinforcing boss 2223 on the fixed bracket 222 can further improve the local structural strength of the fixed bracket 222. Through the mating of the mating reinforcing boss 2223 and the reinforcing boss 323, the connection strength and rigidity of the fixed connector 5 are greatly improved.

[0060] In some embodiments, such as Figure 16 As shown, the longitudinal support guide rail 41 has an upwardly open support sliding groove 411, and the longitudinal sliding guide rail 42 includes a guide rail body 421 and a guide rail sliding part 422. The guide rail body 421 is used to connect with the mounting bracket 3, and the guide rail sliding part 422 is used to slide with the longitudinal support guide rail 41.

[0061] Furthermore, the guide rail body 421 is detachably connected to the first connecting part 3121. The guide rail body 421 is located above the longitudinal support guide rail 41. The guide rail sliding part 422 is connected to the bottom of the guide rail body 421 and extends into the support sliding groove 411 to slide and support the inner bottom wall of the support sliding groove 411.

[0062] Specifically, the guide rail body 421 and the first connecting part 3121 can be connected in a detachable manner by means of screw connection, snap connection, plug connection or combination connection. This facilitates the installation and disassembly of the guide rail body 421 and the bracket longitudinal beam 31. When the bracket longitudinal beam 31 is damaged, it can be quickly separated from the guide rail body 421 for repair and replacement, reducing maintenance costs. For example, when the first connecting part 3121 is constructed as a first connecting hole, a second mating hole can be provided on the guide rail body 421. The inner circumferential wall of the second mating hole can have internal threads, so that the bolt connector can be sequentially inserted into the first connecting hole and the second mating hole along the longitudinal direction, and then tightened by the connecting nut to realize the bolted connection and fixation between the guide rail body 421 and the support longitudinal beam 31. When the first connecting part 3121 is constructed as a snap or a snap protrusion, a slot can be provided on the guide rail body 421. The snap is inserted into the slot to realize the snap connection and fixation between the guide rail body 421 and the support longitudinal beam 31. Of course, the guide rail body 421 and the support longitudinal beam 31 can also be welded or riveted, which can be flexibly set, and will not be elaborated here.

[0063] Among them, such as Figure 7 and Figure 16 As shown, both the guide rail body 421 and the longitudinal support guide rail 41 extend along the front-rear direction of the vehicle. The guide rail body 421 is located above the longitudinal support guide rail 41. The guide rail body 421 is constructed as a long strip-shaped sliding block. The guide rail sliding part 422 is connected to the bottom of the guide rail body 421. The guide rail sliding part 422 extends downward into the support sliding groove 411. The outer peripheral wall of the guide rail sliding part 422 can press against the inner bottom wall of the support sliding groove 411 to slide along the length direction of the support sliding groove 411. The front-rear sliding can be achieved by rolling friction or rolling friction, thereby realizing the longitudinal sliding guide rail 42 sliding longitudinally along the longitudinal support guide rail 41, and realizing the front-rear sliding of the seat assembly 100.

[0064] In some embodiments, the support longitudinal beam 31 includes a longitudinal beam body 311 and two longitudinal beam support plates 312. The longitudinal beam body 311 is connected to the fixed plate assembly 22. The two longitudinal beam support plates 312 are respectively connected to both ends of the longitudinal beam body 311 and extend downward relative to the longitudinal beam body 311. Each of the two longitudinal beam support plates 312 is provided with a first connecting portion 3121, and the two longitudinal beam support plates 312 extend to both ends of the guide rail body 421 to be detachably connected to the guide rail body 421.

[0065] Specifically, such as Figure 8As shown, the support longitudinal beam 31 includes a longitudinal beam body 311 and two longitudinal beam support plates 312. The longitudinal beam body 311 extends in the front-rear direction. One longitudinal beam support plate 312 is connected to the front end of the longitudinal beam body 311, and the other longitudinal beam support plate 312 is connected to the rear end of the longitudinal beam body 311. A portion of both longitudinal beam support plates 312 extends downward relative to the longitudinal beam body 311. A portion of the longitudinal beam support plate 312 located on the front side can be slightly tilted forward, and at least a portion of the longitudinal beam support plate 312 located on the rear side can be slightly tilted backward to facilitate connection to the guide rail body 421. In actual design, as... Figure 9 As shown, the longitudinal beam support plate 312 can be attached to the lower surface and inner surface of the longitudinal beam body 311, and then welded or connected by other detachable or non-detachable connection methods, which can be flexibly selected.

[0066] In each support longitudinal beam 31, two longitudinal beam support plates 312 are provided with a first connecting part 3121. The front longitudinal beam support plate 312 can extend to the front end of the guide rail body 421, and the rear longitudinal beam support plate 312 can extend to the rear end of the guide rail body 421. Thus, the rear surface of the front longitudinal beam support plate 312 is attached to the front surface of the guide rail body 421, and the front surface of the rear longitudinal beam support plate 312 is attached to the rear surface of the guide rail body 421. This allows the connector to pass through the first connecting part 3121 and the guide rail body 421, or the first connecting part 3121 can be inserted into the guide rail body 421, so that the two longitudinal beam support plates 312 are detachably connected to the guide rail body 421 respectively.

[0067] In some embodiments, the seat assembly 100 further includes a sliding drive member 6, and the longitudinal support rail 41 and the longitudinal sliding rail 42 are two sets that cooperate one-to-one. Both sets of longitudinal sliding rails 42 are poweredly connected to the sliding drive member 6, and the sliding drive member 6 is adapted to drive the two sets of longitudinal sliding rails 42 to slide longitudinally together.

[0068] Specifically, the sliding drive component 6 serves as the power source, providing the power for longitudinal sliding. There are two sets of longitudinal support rails 41 and longitudinal sliding rails 42, each set of longitudinal support rails 41 slidingly engaging with its corresponding longitudinal sliding rail 42. Both sets of longitudinal support rails 41 and sliding rails are distributed laterally spaced below the two support beams 32. Both sets of longitudinal sliding rails 42 are powered by the sliding drive component 6, allowing the sliding drive component 6 to transmit power to the two sets of longitudinal sliding rails 42, driving them to slide longitudinally along their respective longitudinal support rails 41. This ensures the seat frame 1 can slide stably forward and backward, preventing jamming or slippage. Furthermore, using a single sliding drive component 6 to drive both sets of longitudinal sliding rails 42 together reduces the number of drive components, facilitating a lightweight design for the seat assembly 100.

[0069] In practical design, the sliding drive component 6 can be constructed as a bidirectional drive motor, which realizes the forward and backward movement of the seat frame 1 through forward and reverse rotation. The sliding drive component 6 can be connected to a transmission structure composed of a worm gear and a lead screw and nut mechanism. The transmission structure is also connected to the longitudinal sliding guide rail 42. For example, the motor shaft of the bidirectional drive motor is connected to the worm, the worm meshes with the worm wheel and extends laterally, the worm wheel is fixedly connected to the lead screw, the lead screw is fixed to the longitudinal support guide rail 41 and extends longitudinally and is coaxially fixedly connected to the worm wheel, and the nut is connected to the longitudinal sliding guide rail 42 and threadedly engages with the lead screw or the longitudinal sliding guide rail. 42 engages with the lead screw thread. When the bidirectional drive motor rotates forward, it drives the worm gear to rotate, which in turn drives the worm wheel to rotate. The worm wheel then drives the lead screw to rotate, and the lead screw rotation, through the thread engagement, causes the longitudinal sliding guide 42 to move linearly along the axis of the lead screw. This allows the longitudinal sliding guide 42 to slide forward along the longitudinal support guide 41, thus enabling the seat frame 1 to slide forward. Conversely, when the bidirectional drive motor rotates in reverse, the worm gear and lead screw nut mechanism causes the longitudinal sliding guide 42 to slide backward along the longitudinal support guide 41, thus enabling the seat frame 1 to slide backward.

[0070] In other embodiments, the seat assembly 100 further includes a rotation drive 7, which is poweredly connected to the rotating disk assembly 21 to drive the rotating disk assembly 21 to rotate relative to the fixed disk assembly 22.

[0071] Specifically, the rotation drive 7 is a power source that provides the power for rotation. The rotation drive 7 is connected to the rotating disk assembly 21 so that the rotation drive 7 can transmit power to the rotating disk assembly 21, driving the rotating disk assembly 21 to rotate relative to the fixed disk assembly 22. When the rotating disk assembly 21 rotates, it drives the seat frame 1 to rotate synchronously, thereby realizing the rotation of the seat frame 1.

[0072] In practical design, the rotation drive component 7 can be configured as a bidirectional drive motor. The motor shaft of the drive motor is connected to a drive gear via a reduction gear transmission structure. A large gear can be mounted on the rotating disk 211, meshing with the drive gear. This drives the drive motor to rotate the drive gear, which in turn drives the large gear. The large gear then drives the rotating disk 211 to rotate relative to the fixed disk assembly 22, thus achieving the rotation function of the seat assembly 100. Alternatively, the large gear can be mounted on the fixed bracket 222. The drive motor then drives the drive gear to rotate, but the drive gear cannot rotate the large gear. Instead, the drive gear rotates around the large gear, thus achieving both rotation and revolution of the drive gear. This transmits power to the motor bracket fixed on the rotating disk 211, which in turn drives the rotating disk 211 to rotate relative to the fixed disk assembly 22, achieving the rotation function of the seat assembly 100.

[0073] The present invention also proposes a vehicle.

[0074] The vehicle according to an embodiment of the present invention includes the seat assembly 100 of any of the above embodiments.

[0075] The design incorporates several key features. The rotating structure 2 enables the seat assembly 100 to rotate, maximizing interior space and enhancing passenger comfort. The longitudinal sliding rail structure 4 allows the seat assembly 100 to slide forward and backward, increasing space in the third row or trunk, and expanding the second-row aisle, even when the second-row seats are not in use. The mounting bracket 3 connects the rotating structure 2 to the longitudinal sliding rail structure 4, ensuring stable support for both the seat frame 1 and the rotating structure 2, reducing deformation, and facilitating stable longitudinal sliding of both structures. The mounting bracket 3 also provides a connection point between the fixed plate assembly 22 and the longitudinal sliding rail structure 42, ensuring a smooth transition and preventing the seat assembly 100 from being unable to connect directly.

[0076] According to an embodiment of the present invention, by providing the aforementioned seat assembly 100, the vehicle can effectively improve the riding comfort of passengers and optimize the utilization of interior space.
