[0046] like Figure 1As shown, the seat 100 may specifically include: a backrest assembly, a seat cushion assembly and a slide rail assembly; wherein the seat cushion assembly includes a seat cushion frame 21 and a seat cushion bracket 22, and the slide rail assembly includes a first track 31 and a second track 32; the backrest assembly is connected to the seat cushion frame 21, the seat cushion frame 21 is rotatably connected to the seat cushion bracket 22, the seat cushion bracket 22 is fixedly connected to the first track 31, and the first track 31 is slidably connected to the second track 32.

[0047] Specifically, the cushion frame 21 of the cushion assembly is a component for mounting the cushion of the seat 100, and the cushion bracket 22 is a component fixedly connected to the slide rail assembly and supports the entire seat 100. One end of the cushion frame 21 is connected to the backrest assembly, and the other end is also rotatably connected to the cushion bracket 22. In actual application, when the user tilts the backrest assembly of the seat 100 in a first direction to facilitate entering the rear seat 100, the cushion frame 21 can rotate around the cushion bracket 22 in the first direction.

[0048] Furthermore, the slide rail assembly includes a first rail 31 and a second rail 32 that are slidably connected to each other, wherein the second rail 32 is fixed to the vehicle floor, the first rail 31 is slidably connected to the second rail 32, and the first rail 31 is also locked to the second rail 32 by a slide rail locking mechanism. Therefore, when the user needs to adjust the position of the seat 100, the first rail 31 can slide in the first direction or the second direction relative to the second rail 32 by unlocking the slide rail locking mechanism. When the user does not need to adjust the position of the seat 100, the first rail 31 is fixedly connected to the second rail 32 by the slide rail locking mechanism.

[0049] In actual application, the backrest assembly of the seat 100 may also include an unlocking handle 14 and a backrest tilting mechanism, wherein the unlocking handle 14 and the backrest tilting mechanism are arranged on the backrest frame 11 of the backrest assembly, and the unlocking handle 14 is used to control the tilting of the backrest tilting mechanism; when the user needs to enter the rear seat 100, the unlocking handle 14 can be pressed, so that the backrest tilting mechanism drives the backrest frame 11 to tilt forward, and after the backrest frame 11 tilts forward, the seat cushion frame 21 will be driven to rotate forward around the seat cushion bracket 22, thereby driving the backrest frame 11 to rotate forward, and when the first track 31 is released from the locking connection with the second track 32 and slides forward, the rotation and the sliding of the first track 31 can be superimposed on each other, so that the sliding stroke of the first track 31 can be reduced while satisfying the user's need to easily enter the rear seat 100.

[0050] In the embodiment of the present application, the seat cushion assembly further includes a first driving mechanism 23 , and the first driving mechanism 23 is respectively connected to the seat cushion bracket 22 and the seat cushion frame 21 .

[0051] Specifically, the seat cushion frame 21 is rotatably connected to the seat cushion bracket 22, and the two ends of the first driving mechanism 23 are respectively connected to the seat cushion bracket 22 and the seat cushion frame 21, so that when the first driving mechanism 23 releases the driving force, the driving force can be transmitted between the seat cushion frame 21 and the seat cushion bracket 22. In actual application, when the user needs to adjust the angle and position of the seat 100, when the user tilts the backrest assembly toward the first direction, the first driving mechanism 23 can be used to drive the seat cushion frame 21 to rotate around the seat cushion bracket 22, thereby driving the backrest assembly to rotate together and move forward, thereby increasing the space for the user to enter the rear seat 100.

[0052] In the embodiment of the present application, the seat cushion bracket 22 includes a lower plate 221 and a cross tube 222, and the seat cushion frame 21 includes an upper plate 211; the lower plate 221 is fixedly connected to the first track 31, and the cross tube 222 is fixedly connected to the lower plate 221; the first driving mechanism 23 is a seat cushion lifting torsion rod 231 with one end fixedly connected to the cross tube 222 and the other end fixedly connected to the upper plate 211.

[0053] Specifically, the lower side panel 221 can be arranged at the front end of the first track 31 and fixed on the first track 31. A lower side panel 221 is arranged on both sides of the left and right sides of the seat 100. The upper side panel 211 is provided with a mounting hole 2111 for passing through the cross tube 222. The two ends of the cross tube 222 are respectively connected to the two lower side panels 221 and pass through the mounting holes 2111 of the upper side panels 211 on both sides. The cross tube 222 and the upper side panel 211 are also connected by a connecting piece 2112 to enhance the structural stability of the seat cushion assembly. A limiting hole 2113 is also arranged on the side of the upper side panel 211 close to the front end. One end of the seat cushion lifting torsion rod 231 is connected to the cross tube 222, and the other end is exposed to the cross tube 222 and is torsionally connected to the limiting hole 2113 of the upper side panel 211.

[0054] In actual application, when the backrest assembly is tilted toward the first direction, the seat cushion lifting torsion bar 231 is torsionally connected to the seat cushion frame 21 and the seat cushion bracket 22, so the seat cushion lifting torsion bar 231 can release its own restoring force to drive the seat cushion frame 21 to rotate around the seat cushion bracket 22.

[0055] In the embodiment of the present application, the seat cushion frame 21 is also provided with a first locking mechanism 212, and the first locking mechanism 212 is movably connected to the first rail 31, and the first locking mechanism 212 and the first rail 31 have a first connection state and a second connection state; in the first connection state, the first locking mechanism 212 is locked and connected to the first rail 31, and in the second connection state, the first locking mechanism 212 is disconnected from the first rail 31, so that the seat cushion lifts the torsion bar 231 to release its own restoring force.

[0056] Specifically, the first locking mechanism 212 is arranged between the seat cushion frame 21 and the first rail 31, and is configured to be locked and connected with the first rail 31. A first locking mechanism 212 is arranged on both sides of the seat cushion frame 21, so as to strengthen the connection effect between the seat cushion assembly and the slide rail assembly and prevent the seat cushion assembly from shifting. By way of example, the structure of the first locking mechanism 212 can be selected from one of an embedded nose hanging structure, an external detachable nose hanging structure, and a press-type unlocking nose structure.

[0057] In actual application, when the first locking mechanism 212 is connected to the first track 31, the seat cushion frame 21 is locked to the first track 31 and cannot rotate around the seat cushion bracket 22; when the user needs to enter the rear seat 100, the first locking mechanism 212 and the first track 31 are disconnected. At the same time, the seat cushion lifting torsion bar 231 twistedly connected between the seat cushion bracket 22 and the seat cushion frame 21 can release its own restoring force, thereby driving the seat cushion frame 21 to rotate around the seat cushion bracket 22.

[0058] In the embodiment of the present application, the seat 100 further includes a linkage adjustment mechanism, which is respectively connected to the seat cushion frame 21 and the backrest assembly.

[0059] Specifically, the linkage adjustment mechanism is disposed on one of the left and right sides of the seat 100, and the seat cushion frame 21 and the backrest assembly are connected through the linkage adjustment mechanism. In actual application, when the backrest assembly is tilted toward the first direction, the linkage adjustment mechanism can drive the first locking mechanism 212 to disconnect from the first track 31, thereby triggering the first driving mechanism 23 to release its own restoring force to drive the seat cushion frame 21 to rotate around the seat cushion bracket 22.

[0060] Reference Figures 2 to 3 In the embodiment of the present application, the linkage adjustment mechanism includes a lower connecting plate 41, a rotating adjustment member 42 and a first unlocking member, and the backrest assembly includes a backrest frame 11 and a follower 12; wherein the rotating adjustment member 42 is rotatably connected to the lower connecting plate 41, one end of the first unlocking member is connected to the rotating adjustment member 42, and the other end is connected to the first locking mechanism 212, the lower connecting plate 41 connects the backrest frame 11 and the seat cushion frame 21, and the follower 12 is fixedly connected to the backrest frame 11 and rotates with the backrest frame 11.

[0061] Specifically, the front end of the seat cushion frame 21 is rotatably connected to the seat cushion bracket 22, and the rear end of the seat cushion frame 21 is connected to the backrest assembly through the lower connecting plate 41; the backrest frame 11 also includes an upper connecting plate 13, and the follower 12 is fixedly connected to the backrest frame 11 through the upper connecting plate 13. In actual application, the follower 12 is used to drive the rotary adjustment member 42 to rotate around the lower connecting plate 41, so as to pull the first unlocking member to release the connection between the first locking mechanism 212 and the first track 31.

[0062] In the embodiment of the present application, a first axle pin 421 and a limiting groove 412 are provided on the lower connecting plate 41, and the rotary adjustment member 42 is rotatably connected to the lower connecting plate 41 through the first axle pin 421, and the first axle pin 421 passes through the limiting groove 412 so that the follower 12 can abut against the first axle pin 421.

[0063] Specifically, the lower connecting plate 41 and the rotating adjusting member 42 are rotationally connected via the rotating adjusting member shaft 411. After the rotating adjusting member 42 is connected to the lower connecting plate 41, the first axle pin 421 passes through the limiting groove 412 on the lower connecting plate 41, and the length of the first axle pin 421 is sufficient to abut against the follower 12, so that when the backrest frame 11 tilts in the first direction, the follower 12 can push the first axle pin 421 to rotate in the second direction along the limiting groove 412, and drive the rotating adjusting member 42 to rotate in the second direction. The rotation of the rotating adjusting member 42 pulls the first unlocking member, and the first unlocking member unlocks the first locking mechanism 212.

[0064] It should be noted that the limiting groove 412 is configured as a crescent groove structure. When the backrest frame 11 tilts forward, when the first axle pin 421 moves to abut the limiting groove 412, the backrest frame 11 no longer tilts forward. In practical applications, the forward tilt angle of the backrest frame 11 can be adjusted by adjusting the size of the limiting groove 412 of the lower connecting plate 41, so as to match the interior space of different vehicle models.

[0065] Reference Figure 4 The first unlocking member includes a first cable 43, an unlocking link 44, an unlocking link shaft 45 and a second cable 46; wherein the unlocking link 44 includes a first end and a second end, and the unlocking link shaft is connected between the first end and the second end so that the unlocking link 44 rotates around the unlocking link shaft 45; one end of the first cable 43 is connected to the rotation adjustment member 42, and the other end is connected to the first end of the unlocking link 44; one end of the second cable 46 is connected to the second end of the unlocking link 44, and the other end is connected to the first locking mechanism 212.

[0066] Specifically, the first cable 43 is located at the bottom of the unlocking link 44. The rotation of the rotary adjustment member 42 drives the first cable 43 to rotate the first end of the unlocking link 44 downward, and the second end of the unlocking link 44 upward. Thus, the third cable 15 can pull the first locking mechanism 212 to rotate upward to unlock the first locking mechanism 212.

[0067] It should be noted that the third cable 15 is divided into a third cable first branch and a third cable second branch through a cable splitter, so as to be used to pull the first locking mechanism on the left and right sides of the seat respectively. In practical applications, by adjusting the length of the two ends of the unlocking link 44, the small-stroke cable can unlock the large-stroke cable, so that the unlocking has a linkage sequence.

[0068] In the embodiment of the present application, the seat cushion assembly also includes a seat cushion lifting mechanism, the two ends of which are rotatably connected to the upper plate 211 and the lower plate 221 respectively, and the seat cushion lifting mechanism is rotatably connected to the upper plate 211.

[0069] In actual application, when the seat cushion frame 21 rotates around the seat cushion bracket 22, since the two ends of the seat cushion lifting mechanism are respectively connected to the upper plate 211 and the lower plate 221 of the seat cushion frame 21, they can rotate along with the rotation of the seat cushion frame 21, providing further driving force for the seat cushion frame 21 to rotate forward.

[0070] In an embodiment of the present application, the seat cushion lifting mechanism includes a seat cushion lifting link 24 and a plurality of seat cushion lifting link shafts 25; wherein, among the plurality of seat cushion lifting link shafts 25, at least one is fixedly connected to the lower side plate 221, and at least one is fixedly connected to the upper side plate 211, and the seat cushion lifting link 24 is rotatably connected to the plurality of seat cushion lifting link shafts 25.

[0071] Specifically, the upper side panel 211, the lower side panel 221, and the seat cushion lifting link 24 are all made of metal materials. In actual applications, the rear lifting angle of the seat 100 required by different vehicle spaces can be matched by changing the structural lengths of the lower side panel 221 and the seat cushion lifting link 24.

[0072] Further, refer to Figure 7 The first track 31 is provided with a slide rail unlocking axle pin 311, and the slide rail locking mechanism includes an unlocking sheet metal 33 and an unlocking sheet metal rotating shaft 34. The seat cushion lifting link 24 is also provided with a second axle pin 241, and the second axle pin 241 is arranged along the width direction of the seat 100 and extends to abut against the slide rail unlocking sheet metal 33; when the seat cushion lifting link 24 rotates forward, the second axle pin 241 abuts against the unlocking sheet metal 33 and pushes the unlocking sheet metal 33 to rotate forward around the unlocking sheet metal rotating shaft 34 until the unlocking sheet metal 33 presses the slide rail unlocking axle pin 311 to release the locking connection between the first track 31 and the second track 32.

[0073] In the embodiment of the present application, the seat 100 also includes a recliner 50 and a second unlocking mechanism, the backrest assembly also includes a backrest tilting mechanism and an upper connecting plate 13, the recliner 50 is connected to the upper connecting plate 13 and is linked to the backrest tilting mechanism, one end of the second unlocking mechanism is fixed to the backrest frame 11, and the other end is connected to the recliner 50; in actual application, the second unlocking mechanism is used to unlock the recliner 50 to trigger the backrest tilting mechanism to release its own restoring force to drive the backrest frame 11 to tilt in the first direction.

[0074] Specifically, the second unlocking mechanism includes an unlocking handle 14 and a third cable 15. The unlocking handle 14 is fixedly connected to the backrest frame 11. One end of the third cable 15 is connected to the unlocking handle 14, and the other end is connected to the recliner 50. When the unlocking handle 14 is pulled, the third cable 15 pulls the recliner 50 to unlock the recliner 50.

[0075] Further, refer to Figure 6 The backrest tilting mechanism includes a backrest tilting torsion bar 16, a torsion bar fixing sheet metal 17, a torsion bar pressing plate 18 and a torsion bar fixing bolt 19; wherein, one end of the backrest tilting torsion bar 16 is bent into a U-shape and clamped to the lower connecting plate 41 on the right side of the backrest frame 11, and one end is pressed on the torsion bar fixing sheet metal 17 by the torsion bar pressing plate 18 through the torsion bar fixing bolt 19, and the deformation restoring force of the material itself is used to provide the backrest with an automatic tilting force, and these parts are all made of metal materials. In practical applications, in order to achieve different backrest tilting forces, the backrest tilting torsion bar 16 can be changed in diameter, material, and bending shape.

[0076] In practical applications, when a user needs to enter the rear seat 100, the user can easily enter the rear seat 100 by pressing the unlocking handle 14 of the seat 100. The working process of the seat 100 provided in the embodiment of the present application is described below:

[0077] The unlocking handle 14 of the second unlocking mechanism is pulled, and the unlocking handle 14 pulls the third cable 15 to unlock the recliner 50, so that the backrest frame 11 is unlocked, and the backrest forward tilting torsion bar 16 of the backrest forward tilting mechanism releases its own restoring force, driving the backrest frame 11 to tilt forward;

[0078] The follower 12 of the backrest frame 11 rotates forward accordingly until it abuts against the first shaft pin 421 on the rotation adjustment member 42, and pushes the first shaft pin 421 to rotate backward along the limiting groove 412 until the first shaft pin 421 abuts against the rear end of the limiting groove 412, and the backrest frame 11 stops tilting forward; while the first shaft pin 421 rotates backward, the rotation adjustment piece rotates backward synchronously, thereby pulling the first cable 43 backward, and the first cable 43 pulls the first end of the unlocking link 44 downward, so that the second end of the unlocking link 44 tilts up, and at the same time, the second end of the unlocking link 44 pulls the third cable 15 to unlock the first locking mechanism 212, thereby releasing the locking connection between the seat cushion frame 21 and the first track 31;

[0079] When the seat cushion frame 21 is disconnected from the first track 31, the seat cushion lifting torsion bar 231 releases its restoring force to drive the seat cushion frame 21 to rotate forward around the cross tube 222, and the rear end of the seat cushion frame 21 is lifted. At the same time, the seat cushion lifting connecting rod 24 rotates around the seat cushion lifting connecting rod rotating shaft 25 until the rotation stops. The rear end of the seat cushion frame 21 is lifted to the highest height, and the forward movement distance reaches the maximum.

[0080] While the seat cushion lifting link 24 rotates around the seat cushion lifting link shaft 25, the second axle pin 241 of the seat cushion lifting link 24 abuts against the unlocking sheet metal 33 and pushes the unlocking sheet metal 33 to rotate forward around the unlocking sheet metal shaft 34 until the unlocking sheet metal 33 presses the slide rail unlocking axle pin 311 to release the locking connection between the first track 31 and the second track 32, and the entire seat 100 can move freely forward and backward.

[0081] In summary, in the embodiment of the present application, the seat cushion assembly includes a seat cushion frame and a seat cushion bracket that are rotatably connected. When the backrest assembly is tilted toward a first direction, the seat cushion frame can rotate relative to the seat cushion bracket and drive the backrest assembly to rotate toward the first direction, so that the seat can have a moving stroke toward the first direction. When the first track slides toward the first direction relative to the second track, the moving stroke and the sliding stroke of the first track can be superimposed. While meeting the user's need to easily enter the rear seat, it is also beneficial to reduce the sliding stroke of the first track, thereby reducing the size of the slide rail assembly along the length direction of the vehicle body, providing the user with a more spacious foot moving space, and improving the user experience.

[0082] An embodiment of the present application also discloses a vehicle, which includes the seat as described above.

[0083] It should be noted that the vehicle disclosed in the embodiment of the present application has the same or similar beneficial effects as the seat described above, which will not be repeated here.
