[0022] Unless otherwise specified, the front-back direction in this invention 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.

[0023] The following is for reference. Figures 1-14 The seat assembly 100 according to an embodiment of the present invention allows the zero-gravity seat to slide left and right and forward and backward, improving the convenience of seat adjustment and user experience.

[0024] like Figures 1-6 As shown, the seat assembly 100 according to an embodiment of the present invention includes: a seat frame 1, a leg support structure 2, a transverse slide rail structure 3, a slide rail connecting bracket 4, and a longitudinal slide rail structure 5.

[0025] The seat frame 1 includes a seat cushion frame 11 and a backrest frame 12. The seat cushion frame 11 includes a seat cushion body 111 and a seat cushion mounting base 112. The seat cushion body 111 is located above the seat cushion mounting base 112. The rear end of the seat cushion body 111 is rotatably connected to the seat cushion mounting base 112, allowing the front end of the seat cushion body 111 to rise or fall relative to the rear end. The backrest frame 12 is rotatably connected to the rear end of the seat cushion body 111. In other words, by rotatably connecting the rear end of the seat cushion body 111 to the seat cushion mounting base 112, the seat cushion body 111 can rotate relative to the seat cushion mounting base 112, thereby allowing the front end of the seat cushion body 111 to rise or fall. The backrest frame 12 can also rotate relative to the seat cushion body 111, thus enabling adjustment of the seat back and seat cushion.

[0026] Specifically, the rear end of the seat cushion body 111 is rotatably connected to the seat cushion mounting base 112, and the backrest frame 12 is connected to the rear end of the seat cushion body 111, so that the front end of the seat cushion body 111 can rise or fall relative to the seat cushion mounting base 112, and the backrest frame 12 is rotatably connected to the rear end of the seat cushion body 111, so that the backrest frame 12 can rotate relative to the seat cushion frame 11.

[0027] Furthermore, the leg support structure 2 is movably connected to the front end of the seat cushion frame 11 to selectively raise or lower. In other words, the leg support structure 2 can be provided at the front end of the seat cushion frame 11, so that the leg support structure 2 can support the passenger's lower legs and improve the passenger's riding comfort.

[0028] When the seat assembly 100 is in the folded-down state, the backrest frame 12 rotates forward, and the seat cushion body 111 rotates downward around the rear end of the seat cushion mounting seat 112 to lower the front end. The leg support structure 2 can also lower at the front end of the seat cushion frame 11, which reduces the space occupied by the seat assembly 100 in the vehicle. When the seat assembly 100 is fully opened, the backrest frame 12 rotates backward, and the seat cushion body 111 rotates upward around the rear end of the seat cushion mounting seat 112 to raise the front end. The leg support structure 2 can also be raised at the front end of the seat cushion frame 11. At this time, the backrest frame 12, the seat cushion frame 11, and the leg support structure 2 can cooperate with each other to achieve the zero-gravity seat function.

[0029] The transverse slide rail structure 3 includes a transverse sliding guide rail 31 and a transverse support guide rail 32. The longitudinal slide rail structure 5 includes a longitudinal sliding guide rail 52 and a longitudinal support guide rail 51. The seat cushion mounting base 112 is mounted on the transverse sliding guide rail 31. The transverse sliding guide rail 31 is slidably mounted on the transverse support guide rail 32 in the transverse direction. The transverse support guide rail 32 is mounted on the longitudinal sliding guide rail 52 through the slide rail connecting bracket 4. The longitudinal sliding guide rail 52 is slidably mounted on the longitudinal support guide rail 51 in the longitudinal direction.

[0030] In other words, the transverse slide rail structure 3 and the longitudinal slide rail structure 5 can be installed and fixed through the slide rail connecting bracket 4, so that the seat frame 1 and the leg support structure 2 can slide laterally through the transverse slide rail structure 3 and longitudinally through the longitudinal slide rail structure 5, thereby flexibly adjusting the position of the seat assembly 100 in the vehicle.

[0031] Specifically, the seat cushion mounting base 112 is mounted on the transverse sliding guide rail 31. The slide rail connecting bracket 4 fixes the transverse support guide rail 32 and the longitudinal sliding guide rail 52, thereby enabling the seat cushion mounting base 112 to slide laterally via the transverse sliding guide rail 31 and longitudinally via the longitudinal sliding guide rail 52, thus realizing the transverse and longitudinal sliding of the seat assembly 100. When the seat assembly 100 needs to slide laterally, it can be pushed laterally by manual, motor drive, or other driving methods, so that the transverse sliding guide rail 31 moves laterally along the transverse support guide rail 32, thereby driving the seat frame 1 and leg support structure 2 connected to the transverse sliding guide rail 31 to move laterally, thus realizing the transverse movement of the seat assembly 100. When the seat assembly 100 needs to move longitudinally, it can be pushed longitudinally by manual, motor drive, or other driving methods, so that the longitudinal sliding guide rail 52 moves longitudinally along the longitudinal support guide rail 51. At this time, the seat frame 1, leg support structure 2, transverse sliding rail structure 3, and sliding rail connecting bracket 4 can all move longitudinally along the longitudinal support guide rail 51 under the drive of the longitudinal sliding guide rail 52. When the seat assembly 100 needs to move longitudinally and laterally at the same time, the seat assembly 100 can be driven to move laterally along the transverse support guide rail 32 via the transverse sliding guide rail 31, and move longitudinally along the longitudinal support guide rail 51 via the longitudinal sliding guide rail 52, so as to realize the flexible movement of the seat assembly 100 in the vehicle space.

[0032] Therefore, the leg support structure 2, backrest frame 12, seat cushion body 111, and seat cushion mounting base 112 enable the seat assembly 100 to function as a zero-gravity seat. Furthermore, the seat assembly 100 can slide laterally and longitudinally via the lateral slide rail structure 3 and the longitudinal slide rail structure 5, facilitating adjustment of its position within the vehicle interior. Moreover, compared to traditional vehicle seats, it features a simpler structure, easier installation, and reduced costs.

[0033] According to an embodiment of the present invention, the seat assembly 100 can realize the function of a zero-gravity seat through the cooperation of the leg support structure 2 and the seat frame 1. The seat can slide forward and backward and slide left and right through the transverse slide rail structure 3 and the longitudinal slide rail structure 5, thereby improving the convenience of seat adjustment and user experience. The transverse support guide rail 32 and the longitudinal slide rail 52 are connected and supported by the slide rail connecting bracket 4, which can realize the stable connection between the transverse slide rail structure 3 and the longitudinal slide rail structure 5, and at the same time increase the overall structural height of the seat assembly 100.

[0034] In some embodiments, the slide rail connecting bracket 4 includes two longitudinal support beams 41 and two transverse support beams 42. The two longitudinal support beams 41 extend longitudinally and are spaced apart laterally, and the two transverse support beams 42 are spaced apart longitudinally and respectively connected between the two longitudinal support beams 41. That is, the slide rail connecting bracket 4 is formed by connecting the two longitudinal support beams 41 and the two transverse support beams 42 together.

[0035] Specifically, such as Figure 2 and Figure 8 As shown, two longitudinal support beams 41 extend longitudinally and are spaced apart laterally. Two transverse support beams 42 are spaced apart longitudinally and connected to the two longitudinal support beams 41 respectively. That is, one transverse support beam 42 is connected to one end of the two longitudinal support beams 41 respectively, and the other transverse support beam 42 is connected to the other end of the two longitudinal support beams 41 respectively, thereby realizing the mutual connection between the two transverse support beams 42 and the two longitudinal support beams 41.

[0036] Among them, there are two transverse sliding guide rails 31 and two transverse support guide rails 32, which are slidably connected in a one-to-one manner. The two transverse support guide rails 32 are connected to the two support beams 42 in a one-to-one manner. There are two longitudinal sliding guide rails 52 and two longitudinal support guide rails 51, which are slidably connected in a one-to-one manner. The two longitudinal sliding guide rails 52 are connected to the two support beams 41 in a one-to-one manner.

[0037] Specifically, the two transverse support rails 32 are connected one-to-one with the two bracket beams 42, allowing the transverse sliding rail 31 to slide laterally on the slide rail connecting bracket 4, thereby driving the seat frame 1 and leg support structure 2 to move laterally. The two longitudinal sliding rails 52 are connected one-to-one with the two bracket beams 41, so that the slide rail connecting bracket 4 can move along the longitudinal support rail 51 under the drive of the longitudinal sliding rail 52, thereby driving the transverse slide rail structure 3, seat frame 1 and leg support structure 2 to move longitudinally.

[0038] Therefore, the support beam 42 and support longitudinal beam 41 on the slide rail connecting bracket 4 can be connected to the transverse slide rail structure 3 and the longitudinal slide rail structure 5 respectively, thereby realizing the transverse and longitudinal movement of the seat frame 1 and the leg support structure 2.

[0039] In some embodiments, each support longitudinal beam 41 includes a longitudinal beam body 411 and two support plates 412. The longitudinal beam body 411 is connected to the support crossbeam 42. The two support plates 412 are connected to both ends of the longitudinal beam body 411 and extend downward relative to the longitudinal beam body 411 in at least a portion. The two support plates 412 extend to both ends of the longitudinal sliding guide rail 52. The support plates 412 and the longitudinal sliding guide rail 52 are connected longitudinally via a first connector. That is, the longitudinal sliding guide rail 52 can be connected to the support longitudinal beam 41 through the support plates 412, thereby realizing the longitudinal sliding of the slide rail connecting bracket 4. The slide rail connecting bracket 4 can drive the transverse slide rail structure 3, the seat frame 1, and the leg support structure 2 to slide longitudinally.

[0040] Specifically, such as Figure 8 As shown, the main body 411 of the two support beams 41 is connected to the support beam 42. The support plate 412 is set on both sides of the main body 411 of the beam and extends downward, so that the support plate 412 can extend to the longitudinal sliding guide rail 52. Then the support plate 412 and the longitudinal sliding guide rail 52 can be connected by the first connector, such as the first connector can be constructed as a bolt, so that the support plate 412 and the longitudinal sliding guide rail 52 are bolted together, so that the slide rail connecting bracket 4 and the longitudinal sliding guide rail 52 are relatively fixed, and the slide rail connecting bracket 4 slides longitudinally on the longitudinal support guide rail 51 along with the longitudinal sliding guide rail 52.

[0041] The bracket plate 412 may be provided with a first through hole 4121, and the first connector may be provided through the first through hole 4121 to be fixedly connected with the longitudinal sliding guide rail 52, thereby realizing the installation and fixation of the bracket longitudinal beam 41 and the longitudinal sliding guide rail 52. The first connector may be constructed as a bolt, screw, or other connector.

[0042] Therefore, the slide rail connecting bracket 4 and the longitudinal sliding guide rail 52 can be fixedly connected through the bracket plate 412, so that the transverse slide rail structure 3, seat frame 1 and leg support structure 2 can slide longitudinally, and the installation is convenient and the connection strength is high.

[0043] In some embodiments, one of the support longitudinal beam 41 and the support transverse beam 42 is provided with an overlapping flange 43, and the other of the support longitudinal beam 41 and the support transverse beam 42 is vertically overlapped with the overlapping flange 43. That is, the overlapping flange 43 can be provided on the support longitudinal beam 41 or on the support transverse beam 42, so that the support transverse beam 42 and the support longitudinal beam 41 can be overlapped and connected.

[0044] Specifically, such as Figure 8As shown, the support beam 42 has downwardly extending overlapping flanges 43 at both ends. The two ends of the support beam 42 are respectively connected to the ends of the two support longitudinal beams 41. At this time, the overlapping flanges 43 on the support beam 42 overlap with the ends of the support longitudinal beams 41, which can increase the contact area between the support beam 42 and the support longitudinal beams 41. The support beam 42 and the support longitudinal beams 41 can be bolted, welded or otherwise connected through the overlapping flanges 43, so that the support beam 42 and the support longitudinal beams 41 are installed and fixed with high connection strength.

[0045] And / or, in other embodiments, the transverse support rail 32 is connected to the support beam 42 by a plurality of second connectors, which are spaced apart laterally on the transverse support rail 32. That is, the transverse support rail 32 and the support beam 42 can be connected by two, three, or more second connectors, and the specific number can be flexibly selected.

[0046] Specifically, the number of second connecting members can be set to two, that is, one support beam 42 can be connected to the transverse support guide rail 32 through two second connecting members. For example, two second through holes 421 can be provided at both ends near the support beam 42, and the two second connecting members can pass through the two second through holes 421 respectively to connect the support beam 42 to the transverse support guide rail 32, thereby realizing the installation and fixation of the slide rail connecting bracket 4 and the transverse slide rail structure 3. The second connecting members can be constructed as bolts, screws, or other connecting members.

[0047] Therefore, by overlapping the flange 43 and the second connector, the relative fixation between the slide rail connecting bracket 4 and the transverse slide rail structure 3, and between the bracket crossbeam 42 and the bracket longitudinal beam 41 can be achieved, and the connection strength is high.

[0048] In some embodiments, there are two seat cushion mounting seats 112, which are distributed laterally at the bottom of the seat cushion body 111. The front ends of the two seat cushion mounting seats 112 are detachably connected to both ends of a transverse sliding guide rail 31, and the rear ends of the two seat cushion mounting seats 112 are detachably connected to both ends of another transverse sliding guide rail 31. That is, the seat frame 1 and the transverse sliding rail structure 3 can be installed and fixed by connecting the two seat cushion mounting seats 112 with the two transverse sliding guide rails 31.

[0049] Specifically, such as Figure 2 , Figure 11 and Figure 14As shown, two seat cushion mounting bases 112 are provided, and the two seat cushion mounting bases 112 are distributed laterally spaced apart. The front ends of the two seat cushion mounting bases 112 are respectively connected to both ends of one of the transverse sliding guide rails 31, and the rear ends of the two seat cushion mounting bases 112 are respectively connected to both ends of the other transverse sliding guide rail 31, thereby realizing the installation and fixation of the seat cushion mounting bases 112 and the transverse sliding guide rails 31. When the seat frame 1 and the leg support structure 2 need to slide laterally, the seat frame 1 can be driven laterally, so that the transverse sliding guide rail 31 can slide and engage with the transverse support guide rail 32, realizing the transverse sliding of the seat assembly 100.

[0050] Therefore, by fixing the seat cushion mounting base 112 to the transverse sliding guide rail 31, the seat frame 1 and the transverse sliding rail structure 3 can be installed and fixed, thereby enabling the seat frame 1 and the leg support structure 2 to slide laterally through the transverse sliding rail structure 3.

[0051] In some embodiments, the seat cushion frame 11 further includes a drive rocker arm 113 and a transmission link 114. One end of the drive rocker arm 113 is rotatably connected to the front end of the seat cushion mounting base 112, and the other end of the drive rocker arm 113 is rotatably connected to one end of the transmission link 114. The other end of the transmission link 114 is rotatably connected to the front end of the seat cushion body 111. That is, the seat cushion body 111 and the front end of the seat cushion mounting base 112 can be movably connected by the drive rocker arm 113 and the transmission link 114.

[0052] Specifically, such as Figure 2 and Figure 4 As shown, the lower end of the drive rocker arm 113 is rotatably connected to the front end of the seat cushion mounting base 112, such as by a pin connection. The other end of the drive rocker arm 113 is rotatably connected to one end of the transmission link 114, and the other end of the transmission link 114 is rotatably connected to the front end of the seat cushion body 111. In other words, the drive rocker arm 113 and the transmission link 114, the drive rocker arm 113 and the seat cushion mounting base 112, and the transmission link 114 and the seat cushion body 111 are all rotatably connected.

[0053] The system also includes a seat cushion drive structure 115. The power output end 1151 of the seat cushion drive structure 115 is connected to a drive rocker arm 113 to drive the drive rocker arm 113 to rotate relative to the seat cushion mounting base 112. The drive rocker arm 113 is adapted to push the front end of the seat cushion body 111 to rise or fall relative to the rear end through a transmission link 114 when rotating. In other words, the drive rocker arm 113 can be driven by the seat cushion drive structure 115, thereby realizing the raising or falling of the front end of the seat cushion body 111.

[0054] Specifically, such as Figures 2-4 , Figure 9 , Figure 12 and Figure 13 As shown, the seat cushion drive structure 115 can be disposed within the seat cushion mounting base 112. The output end of the seat cushion drive structure 115 is connected to the drive rocker arm 113, thereby enabling the seat cushion drive structure 115 to output power to the drive rocker arm 113 to rotate relative to the seat cushion mounting base 112. For example, if it can rotate upward, the end of the drive rocker arm 113 connected to the transmission link 114 drives the transmission link 114 to move, and the transmission link 114 can continue to drive the front end of the seat cushion body 111 to move upward, thereby realizing the upward lifting of the front end of the seat cushion body 111 relative to the rear end. When the seat cushion drive structure 115 causes the drive rocker arm 113 to rotate downward, the end of the drive rocker arm 113 connected to the transmission link 114 can drive the transmission link 114 to move, and the transmission link 114 continues to drive the front end of the seat cushion body 111 to move downward, thereby realizing the downward lowering of the front end of the seat cushion body 111 relative to the rear end.

[0055] Therefore, through the cooperation of the seat cushion drive structure 115, the drive rocker arm 113 and the transmission link 114, the front end of the seat cushion body 111 can be controlled to rise or fall, thereby facilitating the realization of the zero-gravity seat function.

[0056] In some embodiments, the seat cushion mounting base 112, the drive rocker arm 113, and the transmission link 114 are all in two sets and connected in a one-to-one correspondence. The seat cushion drive structure 115 is poweredly connected to the two sets of drive rocker arms 113 to drive the lateral ends of the seat cushion body 111 to rise and fall synchronously. That is to say, the lateral ends of the seat cushion body 111 can be driven to rise or fall synchronously through the two sets of seat cushion mounting bases 112, drive rocker arms 113, and transmission links 114, thereby realizing the function of a zero-gravity seat.

[0057] Specifically, such as Figure 2 and Figure 11 As shown, the seat cushion mounting base 112, drive rocker arms 113, and transmission links 114 are all configured in two sets and connected one-to-one to the lateral ends of the seat cushion frame 11. When the front end of the seat cushion body 111 needs to rise, the seat cushion drive structure 115 can simultaneously drive the two sets of drive rocker arms 113 to rotate upwards. The two sets of drive rocker arms 113 then drive the two sets of transmission links 114 to move, thereby pushing the lateral ends of the seat cushion body 111 upwards. When the front end of the seat cushion body 111 needs to descend, the seat cushion drive structure 115 can simultaneously drive the two sets of drive rocker arms 113 to rotate downwards. The two sets of drive rocker arms 113 then drive the two sets of transmission links 114 to move, thereby lowering the lateral ends of the seat cushion body 111. The two sets of drive rocker arms 113 are rotatably connected one-to-one with the two sets of seat cushion mounting bases 112, so that the two sets of drive rocker arms 113 can rotate upwards or downwards respectively.

[0058] Therefore, by setting the seat cushion mounting base 112, the drive rocker arm 113 and the transmission link 114 into two sets, the lateral ends of the seat cushion body 111 can be driven, that is, the seat cushion body 111 can be raised or lowered, and it has good stability.

[0059] In some embodiments, the leg support structure 2 includes a leg support plate 21 and a linkage assembly 22. The leg support plate 21 is movably connected to the front end of the seat cushion body 111 via the linkage assembly 22. The leg support plate 21 is adapted to be rotated and unfolded to be higher than the seat cushion body 111 and extend horizontally via the linkage assembly 22, or the leg support plate 21 is adapted to be rotated and retracted to be lower than the seat cushion body 111 and extend vertically via the linkage assembly 22. That is, the leg support plate 21 can be rotated relative to the seat cushion body 111 via the linkage assembly 22, thereby realizing the retraction of the leg support plate 21 or the support of the passenger's lower legs.

[0060] Specifically, such as Figures 2-6 As shown, the leg support plate 21 is rotatably connected to the front end of the seat cushion body 111 via the linkage assembly 22. When the seat frame 1 is fully extended, the leg support plate 21 can be rotated and extended via the linkage assembly 22. At this time, the leg support plate 21 is higher than the seat cushion body 111 and extends in the horizontal direction, so that the leg support plate 21 can support the passenger's lower legs. This allows the leg support structure 2 to cooperate with the seat frame 1 to achieve the function of a zero-gravity seat. When the seat frame 1 is folded and stored, the leg support plate 21 can be rotated and stored via the linkage assembly 22. The upper end of the leg support plate 21 is lower than the seat cushion body 111 and extends in the vertical direction, which can reduce the space occupied in the vehicle.

[0061] The linkage assembly 22 includes a first linkage 221 and a second linkage 222. The first linkage 221 and the second linkage 222 are rotatably connected. For example, one end of the first linkage 221 can be rotatably connected to the front end of the seat body 111, and the other end of the first linkage 221 can be rotatably connected to one end of the second linkage 222. The other end of the second linkage 222 is rotatably connected to the leg support plate 21, so that the first linkage 221 and the second linkage 222 can cooperate with each other to drive the leg support plate 21 to rise or fall.

[0062] Thus, the leg support structure 2 can be unfolded and folded up through the leg support plate 21 and the linkage assembly 22, thereby enabling the leg support structure 2 to cooperate with the seat frame 1 to achieve the folding and folding up of the seat assembly 100 or the zero-gravity seat function.

[0063] In some embodiments, the longitudinal support guide 51 is formed with a sliding support groove 513 that is at least partially open upwards, at least a portion of the longitudinal sliding guide 52 extends into the sliding support groove 513, and the longitudinal sliding guide 52 is rolled and supported in the sliding support groove 513 by a rolling element.

[0064] Specifically, such as Figure 7 As shown, the sliding support groove 513 on the longitudinal support guide rail 51 is open upwards, and the longitudinal sliding guide rail 52 extends into the sliding support groove 513 so that the longitudinal sliding guide rail 52 can slide longitudinally within the sliding support groove 513. A rolling element can be disposed between the sliding support groove 513 and the longitudinal sliding guide rail 52, and the rolling element can convert the sliding friction between the longitudinal sliding guide rail 52 and the sliding support groove 513 into rolling friction, which can reduce the sliding resistance when the longitudinal sliding guide rail 52 slides longitudinally, thus facilitating the longitudinal sliding of the seat assembly 100. The rolling element can be constructed as a roller, a wheel, or other circular structural component suitable for rolling.

[0065] And / or, in other embodiments, the longitudinal support guide rail 51 is provided with at least one positioning part 511 and at least one connecting part 512. The positioning part 511 is used for positioning and engaging with the vehicle floor, and the connecting part 512 is used for detachably connecting with the vehicle floor after the positioning part 511 is positioned and engaged with the vehicle floor. That is, the number of positioning parts 511 and the number of connecting parts 512 can be set to two, three, or more, and the specific number can be flexibly selected.

[0066] like Figure 7 As shown, the number of positioning parts 511 can be set to four, and the number of connecting parts 512 can be set to eight. The four positioning parts 511 can be respectively set at both ends near the two longitudinal support guide rails 51. When the longitudinal support guide rails 51 are installed and fixed to the vehicle floor, the four positioning parts 511 can realize the positioning and cooperation between the two longitudinal support guide rails 51 and the vehicle floor. Then, the eight connecting parts 512 can pass through the two longitudinal support guide rails 51 to fix and connect with the vehicle floor. If the connecting parts 512 can be constructed as bolts, the bolt connection between the longitudinal support guide rails 51 and the vehicle floor can be realized, and the connection strength is high.

[0067] Thus, the longitudinal sliding guide rail 52 can slide longitudinally within the sliding support groove 513 via the sliding support groove 513 and the rolling element, and the longitudinal support guide rail 51 can be connected and fixed to the vehicle floor via the positioning part 511 and the connecting part 512, thereby realizing the installation and fixation of the seat assembly 100 in the vehicle with high installation strength.

[0068] The present invention also proposes a vehicle.

[0069] The vehicle according to an embodiment of the present invention includes a seat assembly 100 of any of the above embodiments. The leg rest structure 2 and the seat frame 1 work together to achieve the function of a zero-gravity seat, and the seat can slide forward and backward and left and right via the transverse slide rail structure 3 and the longitudinal slide rail structure 5, thereby improving the convenience of seat adjustment and the user experience.

[0070] The seat assembly 100 can be driven by an electric motor, allowing users to directly adjust the position of the seat assembly 100 through control buttons, the vehicle system, or other means, improving the convenience of user operation. It can also move the second-row seats of the vehicle towards the door, making it easier for users to pass through the second-row seats.
