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 1-20 The present invention describes a seat assembly 100 having lateral and longitudinal sliding functions, which facilitates occupants to make full use of the vehicle interior space and improves riding comfort. The longitudinal slide rail structure 3 has a simple, stable and reliable overall structure and can stably support the seat frame 1 and the lateral slide rail structure 2 to slide stably in the longitudinal direction.

[0025] like Figures 1-20 As shown, a seat assembly 100 according to an embodiment of the present invention includes: a seat frame 1, a transverse slide rail structure 2, and a longitudinal slide rail structure 3.

[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 11 and a seat cushion frame 12. The backrest frame 11 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 12 supports the seat cushion and needs to provide sufficient support to ensure passenger comfort while distributing body pressure. The backrest frame 11 and seat cushion frame 12 are rotatably connected by an adjustment mechanism, allowing the backrest frame 11 to rotate relative to the seat cushion frame 12 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] Both the transverse slide rail structure 2 and the longitudinal slide rail structure 3 are used to move the seat frame 1. The transverse slide rail structure 2 is used to adjust the left and right position of the seat frame 1, and the longitudinal slide rail structure 3 is used to adjust the front and back position of the seat frame 1. The seat frame 1 is mounted on the transverse slide rail structure 2 and is movable laterally via the transverse slide rail structure 2. The transverse slide rail structure 2 is mounted on the longitudinal slide rail structure 3 and is movable longitudinally via the longitudinal slide rail structure 3. That is to say, the seat frame 1 is mounted on the transverse slide rail structure 2, which provides a support mounting point for the seat frame 1, ensuring the stability of the seat frame 1. When the transverse slide rail structure 2 slides laterally, i.e., in the left-right direction of the vehicle, it can drive the seat frame 1 to slide laterally as well, thereby realizing the lateral sliding function of the seat assembly 100. Similarly, the transverse slide rail structure 2 is mounted on the longitudinal slide rail structure 3, which provides a support mounting point for the transverse slide rail structure 2, ensuring the stability of the transverse slide rail structure 2. When the longitudinal slide rail structure 3 slides longitudinally, i.e., in the front-back direction of the vehicle, it can drive the transverse slide rail structure 2 and the seat frame 1 to slide longitudinally as well, thereby realizing the longitudinal sliding function of the seat assembly 100.

[0029] Furthermore, the longitudinal slide rail structure 3 includes a longitudinal support rail 31 and a longitudinal sliding rail 32. The longitudinal support rail 31 is adapted to be positioned and connected to the vehicle floor. The longitudinal sliding rail 32 is connected to the transverse slide rail structure 2. The longitudinal sliding rail 32 is slidably mounted on the longitudinal support rail 31. The longitudinal support rail 31 forms an upwardly open first support groove 314. At least a portion of the longitudinal sliding rail 32 extends downward into the first support groove 314 and is slidably supported on the inner wall of the first support groove 314.

[0030] Specifically, the vehicle floor has a fixed mounting position for the seat assembly 100. The longitudinal support guide rail 31 can be precisely positioned and installed at the fixed mounting position on the vehicle floor to ensure the relative position between the two is stable, avoiding tilting, shaking, or interference with surrounding components due to installation errors, thereby ensuring that all functions of the seat assembly 100 can be performed normally. For example, a positioning part 31111 can be provided on the longitudinal slide rail structure 3, and a positioning mating part can be provided on the vehicle floor. The positioning part 31111 and the positioning mating part are positioned and installed on the vehicle floor through the positioning and mating of the positioning part 31111 and the positioning mating part. The positioning part 31111 can be constructed as a positioning hole, and the positioning mating part can be constructed as a positioning mating hole. The positioning member 72 passes through the positioning hole and the positioning mating hole to achieve the positioning and connection of the longitudinal support guide rail 31 to the vehicle floor. The vehicle floor can be the rear floor of the vehicle.

[0031] The longitudinal support rail 31 supports and guides the longitudinal sliding rail 32. Both the longitudinal sliding rail 32 and the longitudinal support rail 31 extend longitudinally, i.e., in the front-to-back direction of the vehicle. The length of the longitudinal sliding rail 32 can be set to be less than the length of the longitudinal support rail 31. Thus, after the longitudinal sliding rail 32 is installed on the longitudinal support rail 31, the longitudinal sliding rail 32 can slide back and forth along the length of the longitudinal support rail 31. The longitudinal sliding rail 32 is connected to the transverse slide rail structure 2, forming a single integrated structure. When the longitudinal sliding rail 32 slides longitudinally along the longitudinal support rail 31, it can carry the transverse slide rail structure 2 and the seat frame 1 together in a longitudinal motion relative to the longitudinal support rail 31, thereby enabling flexible adjustment of the front-to-back position of the seat frame 1.

[0032] The longitudinal support guide rail 31 is hollow inside and open on the upper side to form an upward-opening first support groove 314. The lower end of the longitudinal sliding guide rail 32 can extend downward and into the first support groove 314, and the outer peripheral wall of the lower end of the longitudinal sliding guide rail 32 can press against the inner wall of the first support groove 314 to slide along the inner wall of the first support groove 314 in the front-back direction. In other words, the inner wall of the first support groove 314 supports the lower end of the longitudinal sliding guide rail 32 so that the longitudinal sliding guide rail 32 can slide stably in the front-back direction.

[0033] Therefore, by setting the transverse slide rail structure 2 and the longitudinal slide rail structure 3, the seat assembly 100 has the functions of transverse sliding and forward and backward sliding, which increases the functionality of the seat assembly 100 and increases the adjustability of the seat assembly 100. It can improve the use of space in the vehicle and make it easier for passengers to make full use of the space in the vehicle. The overall structure of the seat assembly 100 is simple, low in cost, easy to install, and highly integrated.

[0034] Understandably, by setting the longitudinal sliding rail structure 3 to enable the seat assembly 100 to slide forward and backward, the legroom for second-row passengers and the space in the central aisle of the second row can be adjusted by changing the fore-and-aft position of the seat frame 1 when the second-row seats are not in use. This adapts to different needs and improves passenger comfort and convenience. For example, in practice, when passengers are large, the seat frame 1 can be slid backward to increase legroom for second-row passengers, while when passengers are small, the seat frame 1 can be slid forward to reduce legroom for second-row passengers, adapting to different passenger sizes and seating needs. Sliding the seat frame 1 backward can also increase the space in the central aisle of the second row, facilitating passenger entry and exit. When it is necessary to increase the space in the third row or trunk, the seat frame 1 can be slid forward to allow the vehicle to load large items or increase seating space for third-row passengers. Furthermore, by setting the transverse sliding rail structure 2 to enable the seat assembly 100 to slide left and right, the width of the second-row central aisle can be adjusted by adjusting the left and right position of the seat frame 1, thereby changing the size of the second-row central aisle space to adapt to the needs of different scenarios and improve passenger comfort and convenience. For example, in practice, when passengers need to pass through the second row, the seat frame 1 can be slid laterally to both sides of the door to increase the space of the second-row central aisle and facilitate the passage of passengers.

[0035] In addition, by setting the longitudinal slide rail structure 3 to include a longitudinal support guide rail 31 and a longitudinal sliding guide rail 32, with at least a portion of the longitudinal sliding guide rail 32 extending downward into the first support groove 314 and slidably supported on the inner wall of the first support groove 314, the longitudinal support guide rail 31 can stably support the longitudinal sliding guide rail 32 to slide longitudinally, thereby improving the front-to-back sliding stability and reliability of the longitudinal slide rail structure 3. At the same time, the longitudinal sliding guide rail 32 is connected to the transverse slide rail structure 2, and the longitudinal sliding guide rail 32 can drive the transverse slide rail structure 2 and the seat frame 1 to slide stably longitudinally together, preventing the seat assembly 100 from shaking or tilting when sliding back and forth.

[0036] According to an embodiment of the present invention, the seat assembly 100, by providing a transverse slide rail structure 2 and a longitudinal slide rail structure 3, enables the seat assembly 100 to have the functions of lateral sliding and forward and backward sliding, thereby increasing the functionality of the seat assembly 100 and increasing the adjustability of the seat assembly 100. This can improve the use of space in the vehicle, making it easier for occupants to make full use of the interior space and improving riding comfort. By setting the longitudinal slide rail structure 3 to include a longitudinal support guide rail 31 and a longitudinal sliding guide rail 32, with at least a portion of the longitudinal sliding guide rail 32 extending downward into the first support groove 314 and slidably supported on the inner wall of the first support groove 314, the longitudinal support guide rail 31 can stably support the longitudinal sliding guide rail 32 to slide longitudinally, improving the forward and backward sliding stability and reliability of the longitudinal slide rail structure 3. The seat assembly 100 has a simple overall structure, low cost, convenient installation, and high integration.

[0037] In some embodiments, such as Figure 15 and Figure 20 As shown, the longitudinal sliding guide rail 32 includes a longitudinal slide rail body 321 and a longitudinal sliding part 322. The longitudinal sliding part 322 extends along the front-rear direction of the vehicle and is connected to the bottom of the longitudinal slide rail body 321. In actual design, the longitudinal slide rail body 321 can be integrally formed with the longitudinal sliding part 322 or welded together.

[0038] Among them, such as Figure 19 and Figure 20 As shown, the top of the first support groove 314 is open to form a sliding opening 3141, that is, the sliding opening 3141 is open upward. The longitudinal slide rail body 321 is located above the longitudinal support guide rail 31. The longitudinal sliding part 322 is adapted to the shape and size of the sliding opening 3141, so that the longitudinal sliding part 322 can extend downward from the sliding opening 3141 into the first support groove 314, so that the outer peripheral surface of the longitudinal sliding part 322 can press against the inner wall of the first support groove 314 and can slide along the length direction of the first support groove 314, thereby realizing the sliding engagement between the longitudinal sliding part 322 and the longitudinal support guide rail 31.

[0039] In some embodiments, the bottom of the first support groove 314 has two spaced-apart rolling support surfaces, the longitudinal sliding part 322 is connected to two sets of rolling elements 3221, and the longitudinal sliding part 322 is rolled and supported on the two rolling support surfaces in a one-to-one correspondence by the two sets of rolling elements 3221.

[0040] Specifically, such as Figure 19 and Figure 20As shown, the bottom of the first support groove 314 has two rolling support surfaces spaced apart in the left-right direction. One rolling support surface is located on the left side of the bottom of the first support groove 314, and the other rolling support surface is located on the right side of the bottom of the first support groove 314. A set of rolling elements 3221 is connected to the left side of the longitudinal sliding part 322, and another set of rolling elements 3221 is connected to the right side of the longitudinal sliding part 322. The rolling elements 3221 can be constructed as rollers. The set of rolling elements 3221 on the left side contacts the rolling support surface on the left side and can roll along the rolling support surface on the left side. The set of rolling elements 3221 on the right side contacts the rolling support surface on the right side and can roll along the rolling support surface on the right side. Thus, the longitudinal sliding part 322 is supported by the two rolling elements 3221 in a one-to-one correspondence on the two rolling support surfaces. This can convert the sliding friction of direct contact into rolling friction, reduce the friction between the longitudinal sliding part 322 and the first support groove 314, and make the longitudinal sliding part 322 more stable and with less sliding noise.

[0041] In some embodiments, the longitudinal support guide rail 31 includes a groove bottom plate 311 configured as the bottom wall of a first support groove 314. The groove bottom plate 311 includes a mounting plate portion 3111 and two support plate portions 3112. The mounting plate portion 3111 is connected between the two support plate portions 3112 and protrudes downward relative to the support plate portions 3112. The mounting plate portion 3111 is used for positioning connection with the vehicle floor. The upper surfaces of the two support plate portions 3112 are both configured as rolling support surfaces.

[0042] Specifically, such as Figure 19 As shown, the longitudinal support guide rail 31 includes a slide bottom plate 311, which is configured as the bottom wall of the first support slide 314. The slide bottom plate 311 includes a mounting plate portion 3111 and two support plate portions 3112. The mounting plate portion 3111 and the two support plate portions 3112 are both arranged longitudinally. The left end of the mounting plate portion 3111 is connected to one support plate portion 3112, and the right end of the mounting plate portion 3111 is connected to the other support plate portion 3112. Thus, the mounting plate portion 3111 is connected between the two support plate portions 3112. The mounting plate portion 3111 and the two support plate portions 3112 are connected as a whole and together constitute the bottom wall of the first support slide 314. The mounting plate portion 3111 protrudes downwards relative to the surfaces of the two support plates 3112. This increases the local structural strength at the mounting plate portion 3111 and disperses stress. The mounting plate portion 3111 is used for positioning and connecting with the vehicle floor, thereby increasing the connection strength and rigidity between the mounting plate portion 3111 and the vehicle floor, preventing stress concentration that could lead to cracking. Simultaneously, it avoids interference between the rolling element 3221 and the connecting or positioning elements of the longitudinal support guide rail 31 on the vehicle floor.

[0043] The upper surfaces of both support plate portions 3112 are constructed as rolling support surfaces, that is, two sets of rolling elements 3221 are respectively rolled and supported on the upper surfaces of the two support plate portions 3112.

[0044] In some embodiments, the mounting plate portion 3111 is provided with at least one positioning portion 31111 and at least one connecting portion 31112. The at least one positioning portion 31111 and the at least one connecting portion 31112 are distributed longitudinally spaced apart on the mounting plate portion 3111. The positioning portion 31111 is used to position and cooperate with the vehicle floor, and the connecting portion 31112 is used to be detachably connected to the vehicle floor through the connector 71.

[0045] Specifically, the mounting plate 3111 may be provided with one, two, three or more positioning parts 31111 and connecting parts 31112. The positioning parts 31111 are used to install and position the longitudinal support guide rail 31 to ensure that the longitudinal support guide rail 31 is installed accurately and to prevent misalignment. The connecting parts 31112 are used to fasten the longitudinal support guide rail 31 and the vehicle floor to make the connection between the longitudinal support guide rail 31 and the vehicle floor stable and to prevent wobbling or displacement between the two.

[0046] By providing multiple positioning parts 31111, the mounting plate 3111 can be positioned and engaged with the vehicle floor at multiple locations, thereby improving the positioning accuracy of the longitudinal support guide rail 31 and making the seat assembly 100 more precisely installed on the vehicle floor. Furthermore, by providing multiple connecting parts 31112, the mounting plate 3111 can be connected to the vehicle floor at multiple locations, thereby improving the connection stability and reliability between the longitudinal support guide rail 31 and the vehicle floor, ensuring a more secure installation of the longitudinal support guide rail 31 and preventing loosening.

[0047] Furthermore, the positioning part 31111 can be configured as a positioning hole, and the connecting part 31112 can be configured as a connecting hole. The positioning member 72 can be inserted from top to bottom through the positioning part 31111 and the vehicle floor to achieve the positioning engagement between the positioning part 31111 and the vehicle floor, and to achieve the positioning connection between the vehicle floor and the longitudinal support guide rail 31. The connecting member 71 can be inserted from top to bottom through the connecting part 31112 and the vehicle floor to achieve the detachable connection between the connecting part 31112 and the vehicle floor. In actual design, the connecting member 71 can be configured as a connecting bolt to achieve the threaded connection between the connecting part 31112 and the vehicle floor. The connecting member 71 can also be configured as a rivet, screw, etc., which can be flexibly set. The positioning part 31111 can be a positioning pin. The positioning part 31111 can also be configured as a buckle, and a buckle groove can be set on the vehicle floor. The buckle is inserted into the buckle groove to achieve the snap-fit ​​positioning engagement.

[0048] In a specific embodiment, such as Figure 9 As shown, a positioning part 31111 can be provided at the front end of the mounting plate part 3111 and a positioning part 31111 at the rear end of the mounting plate part 3111, thereby achieving overall positioning of the longitudinal support guide rail 31 through the two positioning parts 31111 at the front and rear ends. Furthermore, a connecting part 31112 can be provided at the front end of the mounting plate part 3111, two connecting parts 31112 at the rear end of the mounting plate part 3111, and a connecting part 31112 in the middle of the mounting plate part 3111, thereby achieving a firm connection between the longitudinal support guide rail 31 and the vehicle floor through the four connecting parts 31112.

[0049] In some embodiments, such as Figure 19 As shown, the longitudinal support guide rail 31 includes two transversely spaced and relatively distributed slide side plates 312. The two slide side plates 312 are respectively connected to the ends of the two support plate portions 3112 and extend upward relative to the support plate portions 3112, so that the two slide side plates 312 and the slide bottom plate 311 are connected to form an integral structure and jointly define the first support slide 314. The surfaces of the two slide side plates 312 respectively form the inner sidewalls of the first support slide 314.

[0050] Among them, such as Figure 19 and Figure 20 As shown, the longitudinal sliding part 322 is located between two slide rail side plates 312, and the top of the two slide rail side plates 312 is provided with support flanges 3121 protruding towards each other. The two support flanges 3121 are spaced apart by a certain distance to form a sliding opening 3141. The longitudinal slide rail main body 321 is located above the two support flanges 3121. A part of the longitudinal sliding part 322 is located at the sliding opening 3141 and the other part extends downward into the first support slide rail 314.

[0051] In some embodiments, such as Figure 19 and Figure 20 As shown, the longitudinal support guide rail 31 includes a top cover plate 313, which covers the two slide side plates 312. The top cover plate 313 has a clearance opening 3131 that is vertically opposite to the sliding opening 3141. The clearance opening 3131 is used to pass through the longitudinal sliding part 322. That is, the longitudinal sliding part 322 can pass through the clearance opening 3131 from top to bottom, and then pass through the sliding opening 3141 to extend into the first support slide groove 314.

[0052] The top cover plate 313 can close the sliding opening 3141 and the first support groove 314, preventing dust and other foreign objects from entering the first support groove 314 and causing sliding jamming or blockage. The top cover plate 313 can also enhance the overall structural strength and rigidity of the longitudinal support guide rail 31, so that the longitudinal support guide rail 31 can support the longitudinal sliding guide rail 32 more stably.

[0053] Furthermore, the longitudinal slide rail structure 3 also includes at least one snap-fit ​​fastener 33, which is sleeved on the bottom of the longitudinal support guide rail 31. Both ends of the snap-fit ​​fastener 33 are formed with snap-fit ​​portions 331. The top cover plate 313 is also provided with two downward protruding hook portions 3132, which are snap-fitted and engaged with the two snap-fit ​​portions 331 on both sides of the longitudinal support guide rail 31.

[0054] Specifically, the longitudinal slide rail structure 3 may include one, two, three, or more snap-fit ​​fasteners 33, the shape of which is adapted to the shape and size of the longitudinal support guide rail 31. For example, Figures 18-20 As shown, the snap-fit ​​fastener 33 can be constructed in a U-shape, and the snap-fit ​​fastener 33 has an upwardly open snap-fit ​​interface 332. The snap-fit ​​fastener 33 is suitable for being fitted from bottom to top onto the bottom of the longitudinal support guide rail 31 through the snap-fit ​​interface 332. Both the left and right ends of the snap-fit ​​fastener 33 have snap-fit ​​portions 331, which are constructed as snap-fit ​​grooves. The left and right sides of the top cover plate 313 are also provided with two downwardly protruding snap-fit ​​portions 3132. At least a portion of the snap-fit ​​portions 3132 protrudes outward, so that the two snap-fit ​​portions 3132 respectively snap into the snap-fit ​​portions 331, thereby realizing the snap-fit ​​cooperation between the two snap-fit ​​portions 332 and the two snap-fit ​​portions 331, thereby achieving the relative fixation of the top cover plate 313 and the longitudinal support guide rail 31.

[0055] Among them, such as Figure 19 As shown, the upper surface of the hook portion 3132 and the inner surface of the latch portion 331 are tightly pressed together, thereby achieving the upper and lower limit fixation of the top cover plate 313 and the longitudinal support guide rail 31, and restricting the top cover plate 313 from falling out upward.

[0056] In some embodiments, such as Figure 11 As shown, the transverse slide rail structure 2 includes a transverse support guide rail 21 and a transverse sliding guide rail 22, as follows: Figure 14 As shown, the transverse support rail 21 is connected to the longitudinal sliding rail 32. They can be connected by screwing, riveting, welding, snap-fitting or combination connection, so that the transverse support rail 21 and the longitudinal sliding rail 32 are connected into an integral structure.

[0057] The transverse sliding guide rail 22 is connected to the seat frame 1. It can be connected by means of screwing, riveting, welding, snap-fitting or combination connection, so that the transverse sliding guide rail 22 and the seat frame 1 are connected as an integral structure.

[0058] The transverse sliding guide rail 22 is slidably mounted on the transverse support guide rail 21 along the longitudinal direction. That is, both the transverse sliding guide rail 22 and the transverse support guide rail 21 extend along the left and right direction of the vehicle. The transverse support guide rail 21 is used to support and guide the transverse sliding guide rail 22. The transverse sliding guide rail 22 is mounted on the transverse support guide rail 21 and can slide left and right along the length direction of the transverse support guide rail 21. When the transverse sliding guide rail 22 slides laterally, it can drive the seat frame 1 to slide laterally relative to the transverse support guide rail 21, thereby realizing the flexible adjustment of the left and right position of the seat frame 1.

[0059] Among them, such as Figure 16 and Figure 17 As shown, the interior of the transverse support guide 21 is hollow and forms an upward-opening second support groove 2111. The lower end of the transverse sliding guide 22 can extend downward into the second support groove 2111, and the outer peripheral wall of the lower end of the transverse sliding guide 22 can press against the inner wall of the second support groove 2111 to slide in the left and right directions along the inner wall of the second support groove 2111. In other words, the inner wall of the second support groove 2111 supports the lower end of the transverse sliding guide 22 so that the transverse sliding guide 22 is slidably supported on the inner wall of the second support groove 2111 and can slide stably in the left and right directions.

[0060] In practical design, such as Figure 16 and Figure 17 As shown, the top of the second support groove 2111 has an opening 21111, and two horizontally distributed first sliding flanges 21112 extending downward are formed at the opening 21111 of the second support groove 2111. The lower end of the horizontal sliding guide rail 22 has a second sliding flange 221 that is folded outward and upward. The horizontal sliding part extends from the sliding opening 3141 into the second support groove 2111, and the first sliding flange 21112 and the second sliding flange 221 are pressed together in a horizontal limiting manner to achieve the sliding engagement between the second support groove 2111 and the horizontal sliding guide rail 22, so that the horizontal sliding guide rail 22 can slide stably along the length direction of the second support groove 2111 and prevent misalignment.

[0061] In some embodiments, the longitudinal support rail 31 and the longitudinal sliding rail 32 are two sets that are matched one-to-one, and the two sets of longitudinal sliding rails 32 are connected to the same longitudinal drive member 4. The longitudinal drive member 4 is adapted to drive the two sets of longitudinal sliding rails 32 to slide longitudinally together.

[0062] Specifically, the longitudinal drive component 4 serves as the power source, providing the power for longitudinal sliding. There are two sets of longitudinal support rails 31 and longitudinal sliding rails 32. Each set of longitudinal support rails 31 slides in conjunction with its corresponding longitudinal sliding rail 32. One set of longitudinal support rails 31 and its corresponding longitudinal sliding rail 32 can be spaced apart laterally from the other set. Both sets of longitudinal sliding rails 32 are powered by the longitudinal drive component 4, allowing the drive component 4 to transmit power to the two sets of longitudinal sliding rails 32, driving them to slide longitudinally along their respective longitudinal support rails 31. This ensures the seat frame 1 can slide stably forward and backward, preventing jamming or slippage. Furthermore, using a single longitudinal drive component 4 to drive both sets of longitudinal sliding rails 32 together reduces the number of drive components, facilitating a lightweight design for the seat assembly 100.

[0063] In practical design, the longitudinal drive component 4 can be constructed as a bidirectional drive motor, which realizes the forward and backward sliding of the seat frame 1 through forward and reverse rotation. The longitudinal drive component 4 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 32. 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 31 and extends longitudinally and is coaxially fixedly connected to the worm wheel, and the nut is connected to the longitudinal sliding guide rail 32 and threadedly engages with the lead screw or the longitudinal sliding guide rail. The screw thread 32 engages with the lead screw, so that when the bidirectional drive motor rotates forward, it drives the worm gear to rotate, which in turn drives the worm wheel to rotate, which in turn drives the lead screw to rotate. The rotation of the lead screw, through the thread engagement, drives the longitudinal sliding guide 32 to move linearly along the axis of the lead screw, thus causing the longitudinal sliding guide 32 to slide forward along the longitudinal support guide 31, thereby realizing the forward sliding of the seat frame 1. Correspondingly, when the bidirectional drive motor rotates in reverse, the worm gear and lead screw nut mechanism drives the longitudinal sliding guide 32 to slide backward along the longitudinal support guide 31, thereby realizing the backward sliding of the seat frame 1.

[0064] In some embodiments, the transverse support rail 21 and the transverse sliding rail 22 are two sets that cooperate one-to-one, and the two sets of transverse sliding rails 22 are connected to the same transverse drive member 5. The transverse drive member 5 is adapted to drive the two sets of transverse sliding rails 22 to slide laterally together.

[0065] Specifically, the lateral drive component 5 serves as the power source, providing the power for lateral sliding. There are two sets of lateral support rails 21 and lateral sliding rails 22. Each set of lateral support rails 21 slides in conjunction with its corresponding lateral sliding rail 22. One set of lateral support rails 21 and its corresponding lateral sliding rail 22 can be longitudinally spaced from the other set. Both sets of lateral sliding rails 22 are powered by the lateral drive component 5, allowing the lateral drive component 5 to transmit power to the two sets of lateral sliding rails 22, driving them to slide laterally along their respective lateral support rails 21. This ensures the seat frame 1 can slide stably left and right, preventing jamming or slippage. Furthermore, using a single lateral drive component 5 to drive both sets of lateral sliding rails 22 also reduces the number of drive components, facilitating a lightweight design for the seat assembly 100.

[0066] In actual design, the lateral drive component 5 can be constructed as a bidirectional drive motor, which realizes the left and right sliding of the seat frame 1 by forward and reverse rotation. The lateral drive component 5 can be connected to the transmission structure composed of worm gear and lead screw nut mechanism. The transmission structure is also connected to the lateral sliding guide rail 22. The driving principle is the same as that of the longitudinal slide rail structure 3, which will not be described in detail here.

[0067] And such as Figure 16 As shown, the rear transverse support rail 21 may include a main guide rail 211, a bottom support plate 212, and at least one first bracket 213. The bottom support plate 212 is connected to the bottom of the main guide rail 211. The bottom support plate 212 has a first limiting flange 2121, and the first bracket 213 has a second limiting flange 2131. The first limiting flange 2121 and the second limiting flange 2131 press against each other in the transverse direction to achieve transverse limiting cooperation between the first bracket 213 and the bottom support plate 212. The seat frame 1 is connected to a second bracket 121. The second bracket 121, the first bracket 213, and the transverse sliding rail 22 can be detachably connected by bolts, screws, pins, or other connectors 71. The lower side of the second bracket 121 can be connected to the longitudinal sliding rail 32. Thus, when the rear transverse sliding rail 22 slides laterally along the rear transverse support rail 21, it can drive the first bracket 213 to slide laterally along the bottom support plate 212. At the same time, the second bracket 121 drives the seat frame 1 to slide laterally. This design enhances the strength of the seat assembly 100 at this location, resulting in higher overall strength, greater structural stability, and improved load-bearing capacity.

[0068] like Figure 17 As shown, the front lateral support rail 21 can be detachably connected to the seat frame 1 via at least one third bracket 122.

[0069] In some embodiments, such as Figure 5 As shown, the longitudinal sliding guide rail 32 and the transverse support guide rail 21 are connected by the mounting bracket 6. This further enhances the overall stability and load-bearing capacity of the seat assembly 100.

[0070] In some embodiments, such as Figure 11 As shown, the transverse slide rail structure 2 also includes an intermediate bracket 23, which extends longitudinally. The front end of the intermediate bracket 23 is connected to the front transverse support rail 21, and the rear end of the intermediate bracket 23 is connected to the rear transverse support rail 21. The transverse drive component 5 is supported and installed on the intermediate bracket 23 to protect the transverse drive component 5.

[0071] The present invention also proposes a vehicle.

[0072] The vehicle according to an embodiment of the present invention includes the seat assembly 100 of any of the above embodiments.

[0073] By setting the transverse slide rail structure 2 and the longitudinal slide rail structure 3, the seat assembly 100 has the functions of lateral sliding and front-back sliding, which increases the functionality of the seat assembly 100 and the adjustability of the seat assembly 100. It can improve the use of space in the vehicle and make it easier for passengers to make full use of the space. By setting the longitudinal slide rail structure 3 to include a longitudinal support guide rail 31 and a longitudinal sliding guide rail 32, at least a portion of the longitudinal sliding guide rail 32 extends downward into the first support slide groove 314 and is slidably supported on the inner wall of the first support slide groove 314. This allows the longitudinal support guide rail 31 to stably support the longitudinal sliding guide rail 32 to slide longitudinally, improving the front-back sliding stability and reliability of the longitudinal slide rail structure 3. The overall structure of the seat assembly 100 is simple, low-cost, easy to install, and highly integrated.

[0074] 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.
