[0002] As passengers pay more attention to vehicle comfort, some vehicles' seating assemblies include seats and leg rests. The reasonable design of seats and leg rests can provide good support for passengers' waist and legs, greatly improving passenger comfort. Especially in situations where passengers need to sit for a long time, such as long-distance driving, seats and leg rests can alleviate passenger fatigue to a certain extent and provide passengers with a good riding experience.
[0003] Currently, most leg rests in vehicles are movable relative to the seat. They extend from under the seat when needed to provide leg support and can be hidden under the seat when not in use to avoid taking up interior space.

Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or terminal device that includes said element.
[0030] The following detailed description of a seat assembly and vehicle provided in this application is illustrated with specific embodiments.
[0031] Reference Figures 1 to 5 This application provides a seat assembly including a base 1, a seat basin 2, a leg rest 3, a connecting rod 4, and a drive assembly 5. The seat basin 2, the leg rest 3, and the drive assembly 5 are all disposed on the base 1. One end of the connecting rod 4 is movably connected to the leg rest 3, and the other end of the connecting rod 4 is movably connected to the seat basin 2. The drive assembly 5 is connected to the leg rest 3 and is used to drive the leg rest 3 to lift or lower. The leg rest 3 drives the seat basin 2 to move in conjunction with the connecting rod 4 to adjust the posture of the seat basin 2.
[0032] Specifically, the seat assembly includes a base 1, a seat basin 2, a leg rest 3, a connecting rod 4, and a drive assembly 5. The base 1 forms the bottom structure of the seat assembly. The base 1 is typically made of steel or other alloy materials with good strength and rigidity, and can provide stable support for the seat basin 2, the leg rest 3, and other components of the seat assembly. In the embodiments of this application, as... Figure 4 As shown, the base 1 includes a support base 13, which is the main body of the base 1 and is used to fix it to the floor of the vehicle. Specifically, the structure of the support base 13 is similar to a rectangle or a square, and the four corners of the support base 13 have feet 14, which are fixedly connected to the floor of the vehicle, thereby realizing the installation and fixation of the seat assembly inside the vehicle.
[0033] The seat cushion (2) is located at the bottom of the seat, mainly referring to the seat pad area. It not only affects the comfort of the seat but also has a significant impact on its support, stability, and safety. For example... Figure 4 As shown, the seat basin 2 includes a main body 20 and side panels 21. The side panels 21 are located on both sides of the main body 20 and are fixedly connected to the main body 20. The main body 20 and the side panels 21 can be manufactured into a single piece using an integral molding process, or they can be assembled from independent components. In some embodiments, the main body 20 can be made of materials such as sponge, foam, or fabric, possessing sufficient flexibility and adaptability to the human sitting posture. The side panels 21 can be made of metal, alloy, or composite material with a certain degree of hardness. The connection between the connecting rod 4 and the seat basin 2 is essentially the connection between the connecting rod 4 and the side panels 21.
[0034] Leg rest 3 can support or elevate the passenger's legs, reducing leg fatigue and improving passenger comfort during long journeys. Figure 4 and Figure 5 As shown, the leg support 3 includes a horizontal tube 31 and two brackets 32. The horizontal tube 31 is arranged along the width direction of the vehicle, and the two brackets 32 are located on both sides of the horizontal tube 31. The horizontal tube 31 and the two brackets 32 are used together to support the passenger's leg. One end of the two brackets 32 is hinged to the horizontal tube 31, and the other end of the two brackets 32 is connected to the connecting rod 4.
[0035] One end of the connecting rod 4 is connected to the bracket 32 of the leg rest 3, and the other end is connected to the side wall 21 of the seat 2. The drive component 5 is connected to the bracket 32 of the leg rest 3. The drive component 5 can drive the bracket 32 to rotate relative to the horizontal tube 31, thereby raising or lowering the leg rest 3. During the process of raising or lowering the leg rest 3, the end of the bracket 32 away from the horizontal tube 31 drives the connecting rod 4 to move. The connecting rod 4 drives the seat 2 to move, so that the leg rest 3 drives the seat 2 to move in conjunction with the connecting rod 4. This enables the adjustment of the seat 2's posture, allowing the seat 2 to be in a sitting or lying position, providing a more comfortable riding environment for passengers.
[0036] Figure 2 A side view of a seat assembly with the leg rest 3 in a stowed position is shown, as... Figure 2 As shown, when the leg rest 3 is in the retracted state, the leg rest 3 is placed vertically at the bottom of the seat 2, occupying less space inside the vehicle. Passengers can freely place their legs on the vehicle floor. At this time, the seat 2 is close to a horizontal position, which is suitable for passengers to be in a normal sitting position. Figure 3 A side view of a seat assembly with the leg rest 3 extended is shown, as follows. Figure 3As shown, when the leg rest 3 is extended, it extends beyond the edge of the seat 2, allowing the passenger's legs to rest on it, which helps reduce leg fatigue. At this time, the side of the seat 2 closest to the leg rest 3 tilts upward, making it more suitable for the passenger to lie down.
[0037] In the prior art, the number of components required for adjusting the seat and leg rest 3 in a seat assembly is relatively large, resulting in a complex overall structure and high production costs. However, in this embodiment, the drive assembly 5 and the connecting rod 4 are used. One end of the connecting rod 4 is connected to the leg rest 3, and the other end is connected to the seat basin 2. When the drive assembly 5 drives the leg rest 3 to lift or lower, the leg rest 3 can drive the seat basin 2 in conjunction with the connecting rod 4, thereby adjusting the posture of the seat basin 2. This effectively reduces the number of components in the seat assembly, simplifies the overall structure of the seat assembly, and lowers its production costs.
[0038] Optionally, refer to Figures 1 to 5 In some embodiments of this application, the base 1 includes a first support beam 11 and a second support beam 12; there are at least two first support beams 11, which are arranged along a first direction, and the second support beam 12 is arranged along a second direction. Each end of the second support beam 12 is connected to a first support beam 11, wherein the first direction and the second direction intersect; each first support beam 11 is connected to the seat 2 and the leg rest 3, and the second support beam 12 is connected to the drive assembly 5.
[0039] Specifically, such as Figure 4 As shown, the base 1 also includes a first support beam 11 and a second support beam 12. The first support beam 11 and the second support beam 12 are fixedly connected to the support base 13. The fixed connection can be achieved by fastener assembly or welding. In this embodiment, the support base 13 has multiple connection holes for fasteners such as bolts, screws, and rivets to pass through. The first support beam 11 and the second support beam 12 are fixedly connected to the support base 13 by fasteners. This arrangement facilitates the disassembly and maintenance of the first support beam 11 and the second support beam 12 in the future, ensuring the reliability of the connection between the first support beam 11 and the second support beam 12 and the seat basin 2 and the leg rest 3, respectively. The first support beam 11 and the second support beam 12 are made of steel or alloy materials with good strength and rigidity, which can provide good support for the seat basin 2 and the leg rest 3.
[0040] The first support beam 11 is arranged along a first direction, and the second support beam 12 is arranged along a second direction. The first and second directions intersect. In practical applications, the first direction corresponds to the length direction of the vehicle, and the second direction corresponds to the width direction of the vehicle. There are at least two first support beams 11. Figure 4The exploded view of the seat assembly shows that the base 1 includes two first support beams 11, and a second support beam 12 is disposed between the two first support beams 11. Each end of the second support beam 12 is connected to one of the first support beams 11. The first support beams 11 and the second support beam 12 can be fixedly connected by fasteners such as bolts and screws, or by laser welding, to ensure the reliability of the connection between the first support beams 11 and the second support beam 12. Figure 5 The diagram shows the second support beam 12 fixedly connected to two first support beams 11. This fixed connection effectively improves the structural stability of the base 1, thereby enhancing the stability and durability of the seat assembly. Of course, there can be multiple first support beams 11. For example, there can be three first support beams 11, with one first support beam 11 connected to each end of the second support beam 12, and another first support beam 11 connected to the middle of the second support beam 12. Alternatively, there can be four or more first support beams 11, with each second support beam 12 fixedly connected to multiple first support beams 11. The connection method will not be elaborated here. Multiple first support beams 11 further enhance the stability of the base 1.
[0041] Each first support beam 11 is connected to the seat 2 and the leg rest 3. Taking two first support beams 11 as an example, the seat 2 is connected to one end of the two first support beams 11, and the leg rest 3 is connected to the other end of the two first support beams 11. The drive assembly 5 is connected to the second support beam 12 to realize the installation and fixation of the drive assembly 5. At the same time, the drive assembly 5 is also connected to the leg rest 3 to drive the leg rest 3 to move relative to the first support beam 11, so as to realize the lifting or lowering of the leg rest 3.
[0042] Optionally, refer to Figure 1 and Figure 5 In some embodiments of this application, the first support beam 11 includes a first end 111 and a second end 112, and the second support beam 12 is connected to the first end 111; the leg support 3 is hinged to the first end 111, and the seat 2 is hinged to the second end 112; the drive assembly 5 is used to drive the leg support 3 to rotate relative to the first end 111 so that the leg support 3 is raised or lowered.
[0043] Specifically, the first end 111 and the second end 112 are the two ends of the first support beam 11 along its length. The leg support 3 is hinged to the first end 111, and the seat 2 is hinged to the second end 112. The drive assembly 5 drives the leg support 3 to rotate relative to the first end 111. The leg support 3 is raised when it rotates upward relative to the first end 111, and it is lowered when it rotates downward relative to the first end 111. When the leg support 3 is raised, it drives the seat 2 through the connecting rod 4, causing the seat 2 to move in tandem. The side of the seat away from the leg support 3 rotates upward relative to the second end 112. At this time, the side of the seat 2 closest to the leg support 3 tilts upward. This posture of the seat 2 and the leg support 3 is more suitable for passengers to lie down. When the leg support 3 falls down, the leg support 3 drives the seat 2 to rotate downward relative to the second end 112 through the connecting rod 4, so that the side of the seat 2 away from the leg support 3 rotates downward relative to the second end 112, so that the side of the seat 2 closest to the leg support 3 tilts downward. The seat 2 gradually returns to a horizontal posture. This posture of the seat 2 and the leg support 3 is more suitable for passengers to be in a normal sitting position.
[0044] Optionally, refer to Figure 1 and Figure 5 In some embodiments of this application, the first end 111 is provided with a connecting plate 113, which extends along a third direction, wherein the third direction intersects with the first direction and the second direction respectively; the connecting plate 113 is provided with a hinge portion, the height of the hinge portion in the third direction is higher than the height of the second end 112 in the third direction, and the leg support 3 is hinged to the hinge portion.
[0045] Specifically, the third direction intersects with the first direction and the second direction respectively. In conjunction with the aforementioned embodiments, the first direction corresponds to the length direction of the vehicle, the second direction corresponds to the width direction of the vehicle, and the third direction corresponds to the height direction of the vehicle. The first end 111 is provided with a connecting plate 113, which extends along the height direction of the vehicle. The connecting plate 113 has a flat plate structure. One end of the connecting plate 113 is fixedly connected to the first end 111 of the first support beam 11, and the other end of the connecting plate 113 is provided with a hinge. The connecting plate 113 and the first support beam 11 can be two independent parts, which are assembled or welded together. Alternatively, the connecting plate 113 and the first support beam 11 can be processed into a single piece by an integral molding process, that is, the connecting plate 113 is part of the first end 111.
[0046] The hinge section is higher in the third-order direction than the second end 112 of the first support beam 11 in the third-order direction. The leg rest 3 is hinged to the hinge section, and the seat 2 is hinged to the second end 112. This makes the hinge position of the leg rest 3 higher than the hinge position of the seat 2, so that the position where the leg rest 3 is raised or lowered is closer to the occupant's legs, which is more ergonomic and allows the seat 2 and leg rest 3 to provide the occupant with a more comfortable reclining posture. The end of the connecting plate 113 near the hinge section can be set as a slope, and the inclination of the slope is adapted to the inclination of the seat 2 to reduce the probability of the end of the connecting plate 113 scratching the bottom of the seat 2 and protect the structural integrity of the seat 2.
[0047] Alternatively, the second support beam 12 can be connected to the connecting plate 113 of the two first support beams 11 to increase the height of the second support beam 12, thereby increasing the installation height of the drive assembly 5 and reducing the probability of the drive assembly 5 scraping against the vehicle floor.
[0048] Optionally, in some embodiments of this application, one end of the connecting rod 4 is hinged to the leg support 3, and the other end of the connecting rod 4 is slidably connected to the seat 2. When the driving assembly 5 drives the leg support 3 to lift, one end of the connecting rod 4 is lifted by the leg support 3 and rotates relative to the leg support 3. The other end of the connecting rod 4 slides upward relative to the seat 2, so that the side of the seat 2 closest to the leg support 3 is lifted.
[0049] Optionally, in some embodiments of this application, the seat 2 is provided with a guide rail 22 on at least one side along the second direction, and the connecting rod 4 is slidably connected to the guide rail 22. The second direction is the width direction of the vehicle, and the seat 2 has side panels 21 on both sides along the second direction. The side panels 21 are arranged along the height direction of the vehicle, and the guide rail 22 is provided on one or both side panels 21.
[0050] The number of guide rails 22 is determined by the number of connecting rods 4. The seat assembly in this embodiment includes two connecting rods 4, which are arranged along the second direction on opposite sides of the seat basin 2. The two connecting rods 4 have the same shape and structure to ensure that the lifting height of both sides of the seat basin 2 is consistent. Correspondingly, guide rails 22 are provided on the side walls 21 on both sides of the seat basin 2. The guide rails 22 on both sides are symmetrically arranged. Each connecting rod 4 is slidably connected to one guide rail 22. The guide rails 22 can guide the movement of the connecting rods 4 and restrict the sliding of the connecting rods 4 in a straight line, thereby helping to achieve a smooth lifting of the seat basin 2.
[0051] Furthermore, such as Figure 1As shown, strip-shaped perforations are formed on the side circumferences 21 on both sides of the seat basin 2, forming guide rails 22. A slider 43 is provided at the end of the connecting rod 4. The slider 43 passes through the strip-shaped perforations and can slide along them, thereby achieving a sliding connection between the connecting rod 4 and the guide rail 22. Of course, in other embodiments, the guide rail 22 can also be a groove or similar feature on the seat basin 2; the specific type is not limited in this application.
[0052] Optionally, refer to Figure 2 and Figure 3 In some embodiments of this application, the drive component 5 is a worm gear mechanism, in which the worm 51 is fixedly connected to the leg support 3.
[0053] Specifically, the worm gear mechanism includes a motor, a turbine, and a worm 51. The motor housing is fixed to the second support beam 12 by fasteners. The motor's output shaft is fixedly connected to the turbine, driving the turbine to rotate. The worm 51 meshes with the turbine. The worm gear 51 mechanism can convert the rotational motion of the motor into the linear motion of the worm 51. The end of the worm 51 is fixedly connected to the leg support 3. The forward and reverse rotation of the motor drives the turbine to rotate forward and reverse, causing the turbine to drive the worm 51 to reciprocate. During the movement of the worm 51, it causes the leg support 3 to lift or fall. The worm gear 51 mechanism has high transmission stability and a large transmission ratio, which helps to achieve smooth lifting or falling of the leg support 3, and also helps to meet the driving requirements of the heavy leg support 3.
[0054] Optionally, refer to Figure 1 and Figure 4 In some embodiments of this application, the seat assembly further includes a reinforcing rod 6, which is disposed between two connecting rods 4. The two ends of the reinforcing rod 6 are connected to the two connecting rods 4 in a one-to-one correspondence. The reinforcing rod 6 and the connecting rods 4 can be assembled together using fasteners. The reinforcing rod 6 establishes a connection between the two connecting rods 4, which can improve the stability of the connected movement to a certain extent. Simultaneously, the reinforcing rod 6 enables the synchronous movement of the two connecting rods 4, thereby ensuring that the two sides of the seat basin 2 are raised to the same height, improving passenger comfort. Furthermore, the reinforcing rod 6 also provides a certain degree of constraint on the two connecting rods 4, reducing the probability of the two connecting rods 4 tilting inward or outward. Inward tilting refers to the two connecting rods 4 tilting towards each other, while outward tilting refers to the two connecting rods 4 tilting towards each other. Reducing the probability of the two connecting rods 4 tilting inward or outward helps to ensure the connection between the connecting rods 4, the leg rest 3, and the seat basin 2, thereby ensuring the linkage between the leg rest 3 and the seat basin 2.
[0055] Optionally, refer to Figure 1 and Figure 4In some embodiments of this application, the connecting rod 4 includes a first bent portion 41 and a second bent portion 42. The included angle between the first bent portion 41 and the second bent portion 42 is an obtuse angle. Specifically, the included angle between the first bent portion 41 and the second bent portion 42 refers to the angle formed by the side of the first bent portion 41 facing the basin 2 and the side of the second bent portion 42 facing the basin 2. In some embodiments, the included angle between the first bent portion 41 and the second bent portion 42 can be set to 120° to 150°, forming the bent design of the connecting rod 4. The end of the first bent portion 41 away from the second bent portion 42 is connected to the leg rest 3, and the end of the second bent portion 42 away from the first bent portion 41 is connected to the basin 2.
[0056] The bending design of link 4 helps reduce the probability of interference between link 4 and other components of the seat assembly when connecting link 4 to the seat basin 2 and leg rest 3, making it easier to achieve a smooth connection between link 4, leg rest 3, and seat basin 2. Additionally, as... Figure 2 As shown, the linkage 4 with this structural form allows the first bend 41 to be in a horizontal position when the leg support 3 is in the retracted state. The first bend 41 and the leg support 3 are in a mutually perpendicular state, which helps to distribute the force and maintain the stability of the linkage 4.
[0057] In other embodiments, the connecting rod 4 adopts a three-section bending structure, including a first bending section, a second bending section, and a third bending section. The second bending section is located between the first bending section and the third bending section. One end of the second bending section is connected to the first bending section, and the other end of the second bending section is connected to the third bending section. The included angle between the second bending section and the first bending section is approximately 90° to 120°, and the included angle between the second bending section and the third bending section is approximately 210° to 240°. All of the above included angles refer to the included angles facing the seat basin 2. The end of the first bending section away from the second bending section is connected to the leg rest 3, and the end of the third bending section away from the second bending section is connected to the seat basin 2. This application embodiment also provides a vehicle including the seat assembly of any of the foregoing embodiments. The seat assembly, through the arrangement of the drive component 5 and the connecting rod 4, enables the leg rest 3 to drive the seat basin 2 in conjunction with the connecting rod 4, thereby realizing the adjustment of the seat basin 2's posture. The overall structure of the seat assembly is simple, and the production cost is low, thus helping to control vehicle manufacturing costs.
[0058] It should be understood that the phrase "some embodiments" throughout the specification means that a specific feature, structure, or characteristic related to an embodiment is included in at least one embodiment of this application. Therefore, "some embodiments" appearing throughout the specification does not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.
[0059] Finally, it should be noted that the above description is only a preferred embodiment of this application and is not intended to limit this application.
