[0065] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0066] In the description of this invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., used to indicate orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. The terms "first," "second," "third," and "fourth," used in this invention, are for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0067] In the description of this invention, it should be understood that the terms "connected," "linked," and "fixed," etc., used in this invention should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or a welded connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly defined. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0068] like Figure 1 , Figure 11 and Figure 16As shown, a preferred embodiment of the present invention provides a car folding seat, comprising: a backrest assembly 1 and a seat cushion assembly 2, wherein the backrest assembly 1 is rotatably mounted on the seat cushion assembly 2 and its relative angle with the seat cushion assembly 2 can be adjusted by an angle adjustment structure 3; and a leg assembly, comprising a first support member 4 and a second support member 5, wherein one end of the first support member 4 is rotatably connected to one end of the seat cushion assembly 2 and the other end is rotatably disposed on the car floor; one end of the second support member 5 is rotatably connected to the other end of the seat cushion assembly 2, and the second support member 5 is provided with a means for contact with the car floor. The second locking structure is hinged to the first support member 4 and the second support member 5 via the first linkage rod 7; the unlocking device 8 includes a drive assembly 81 and an unlocking assembly 82. The drive assembly 81 is installed on the backrest assembly 1, and the unlocking assembly 82 is installed on the seat cushion assembly 2. The unlocking assembly 82 is connected to the second locking structure via a floor lock cable; wherein, when the backrest assembly 1 is folded relative to the seat cushion assembly 2, the drive assembly 81 can drive the unlocking assembly 82 to pull the floor lock cable to release the second locking structure from the car floor.

[0069] In the automobile and its folding seat of the present invention, when the seat needs to be folded and stored, the angle adjustment structure 3 causes the backrest assembly 1 to rotate and fold towards the seat cushion assembly 2. During the folding process, the drive component 81 can drive the unlocking component 82 to pull the floor lock cable to release the lock between the second support member 5 and the car floor, facilitating the storage of the second support member 5. In addition, during the folding process, the seat cushion assembly 2 rotates around one end of the first support member 4, and under the action of the first linkage rod 7, the second support member 5 rotates towards the seat cushion assembly 2 for storage. After folding, it rotates along the other end of the first support member 4 and is stored in the storage pit. The automobile folding seat of the present invention can unlock the second locking structure and release the lock between the second support member 5 and the car floor during the folding and storage process of the backrest assembly 1, making the seat storage process convenient and smooth.

[0070] Furthermore, such as Figure 1 and Figure 2 As shown, the system also includes a headrest assembly 9, which includes a first cable, a headrest 91, and a first locking structure 92. The headrest 91 is rotatably mounted on the backrest assembly 1. One end of the first cable is connected to the first locking structure 92, and the other end is connected to the seat cushion assembly 2. When the backrest assembly 1 is folded relative to the seat cushion assembly 2, the first cable can pull the first locking structure 92 to allow the headrest 91 to fold relative to the backrest assembly 1. By connecting one end of the first cable to the seat cushion assembly 2, the headrest 91 can be folded when the backrest assembly 1 is folded relative to the seat cushion assembly 2, eliminating the need for separate operation of the headrest 91 folding process and making the seat folding process simpler.

[0071] Furthermore, such as Figure 2As shown, the first locking structure 92 further includes a mounting bracket 921, a stop member 922, and a first elastic member. The headrest 91 is provided with at least one support member 911, which is rotatably mounted on the mounting bracket 921. The stop member 922 is movably mounted on the mounting bracket 921. The support member 911 abuts against the stop member 922 and can prevent the support member 911 from rotating. One end of the first elastic member is connected to the stop member 922, and the other end of the first elastic member is connected to the mounting bracket 921. One end of the first cable is connected to the stop member 922. Specifically, there are two support members 911, one of which abuts against the stop member 922 and is rotatably connected to the mounting bracket 921 through the second elastic member. The mounting bracket 921 has two snap-fit ​​plates 923. Mounting holes 924 are provided on both side plates of the mounting bracket 921. Two support members 911 are rotatably mounted by passing through the snap-fit ​​plates 923 and mounting holes 924 via rotating shafts 925. An overlapping pin 926 is provided on the outer side of the side plate of the mounting bracket 921. One end of the second elastic member overlaps with the overlapping pin 926, and the other end overlaps with the end of the rotating shaft 925 protruding from the outer side of the side plate of the mounting bracket 921. A mounting shell 927 is also provided between the two snap-fit ​​plates 923. A stop member 922 has a mounting groove 9221 and a stop member located away from the mounting groove 9221. One end is provided with a cable connection hole 9222, the stop member 922 passes through the mounting shell 927, and the mounting groove 9221 and the cable connection hole 9222 are located on both sides of the mounting shell 927. One end of the first elastic member is connected to the mounting groove 9221, and the other end of the first elastic member is connected to the mounting shell 927. The end of the stop member 922 near the mounting groove 9221 is provided with an abutment surface 9223. When the headrest 91 is unfolded, the support member 911 abuts against the abutment surface 9223. The side plate of the mounting frame 921 is also provided with a cable through hole 9211. One end of the first cable passes through the cable through hole 9211 and connects to the cable connection hole 9222. When the backrest assembly 1 is folded towards the seat cushion assembly 2, the first cable is pulled, causing the stop 922 to move towards the mounting housing 927, compressing the first elastic element. This prevents the support 911 from contacting the contact surface 9223. Under the action of the second elastic element, the support 911 rotates towards the backrest assembly 1, achieving folding. When the backrest assembly 1 is unfolded, the first cable is released, freeing the stop 922 from the tension of the first cable. When the headrest 91 is opened by hand, the stop 922 returns to its original position under the action of the first elastic element, causing one of the support 911 to contact the contact surface 9223, thus completing the opening of the headrest 91. The first elastic element is a spring, and the second elastic element is a flat wire spring.

[0072] Furthermore, such as Figures 3 to 7As shown, the seat cushion assembly 2 includes a cushion support assembly 21, a mounting base 22, a sliding assembly 23, and a fourth elastic member 24. The cushion support assembly 21 is slidably mounted on the mounting base 22 via the sliding assembly 23 and can move towards the direction of the first support member 4. The backrest assembly 1 is rotatably mounted on the cushion support assembly 21. One end of the fourth elastic member 24 is connected to the mounting base 22, and the other end is connected to the cushion support assembly 21. The first support member 4 and the second support member 5 are rotatably connected to the mounting base 22. To shorten the turning radius after the seat is folded, the sliding assembly 23, under the action of the fourth elastic member 24, drives the cushion support assembly 21 to move towards the direction of the first support member 4. This reduces the distance between the connection point of the second support member 5 and the mounting base 22 and the pivot point of the first support member 4 when the seat cushion assembly 2 rotates and folds around the end of the first support member 4 connected to the mounting base 22. This shortens the distance between the connection point of the second support member 5 and the mounting base 22 and the pivot point of the first support member 4 when it is rotated and stored to the car floor, allowing the rear seats to be stored without being affected by the front seats.

[0073] Specifically, such as Figure 4 , Figure 5 and Figure 7 As shown, the soft cushion support assembly 21 includes a first support plate 211, two brackets 212, two plate connecting rods 213, and two second support plates 214. Fixing holes 2141 are provided at both ends of the second support plate 214. The two ends of the two plate connecting rods 213 are inserted into the fixing holes 2141 and fixed by welding. One of the plate connecting rods 213 is located below the first support plate 211. The two ends of the brackets 212 are fixedly connected to the two plate connecting rods 213 respectively. The connection between the brackets 212 and the plate connecting rods 213 away from the first support plate 211 is provided with a positioning groove 2121 corresponding to the contour of the plate connecting rods 213. The plate connecting rods 213 are engaged in the positioning grooves 2121 and fixed by welding. One end of the fourth elastic member 24 is connected to the bracket 212. The bracket 212 is provided with a first slot 215. The second cable is engaged in the first slot 215.

[0074] Further, such as Figure 3 and Figure 6As shown, the sliding assembly 23 includes a sliding plate 231, a slide rail 232, and a third locking structure for locking the sliding plate 231 and the slide rail 232. The slide rail 232 is fixedly installed on the mounting base 22, and the soft pad support assembly 21 is fixedly installed on the sliding plate 231. The sliding plate 231 is slidably connected to the slide rail 232. The unlocking assembly 82 is connected to the third locking structure via a second cable to drive the third locking structure to unlock the sliding plate 231 and the slide rail 232. The mounting base 22 includes a connecting rod 221 and two third support plates 222. The two ends of the connecting rod 221 are fixedly connected to the two third support plates 222 respectively. There are two slide rails 232 and two sliding plates 231. The slide rail 232 is fixedly installed on the third support plates 222. The bracket 212 is detachably connected to the sliding plate 231. The first support member 4 and the second support member 5 are rotatably connected to the two ends of the third support plate 222 respectively. During the folding and storage of the backrest assembly 1, the unlocking component 82 pulls the second cable to unlock the third locking structure. Under the action of the fourth elastic element, the slide plate 231 moves on the slide rail 232. Since the bracket 212 and the slide plate 231 are detachably connected, the slide plate 231 can drive the soft cushion support component 21 to move towards the first support component 4, thereby reducing the turning radius of the seat around the end of the first support component 4 that connects to the car floor. This is not affected by the front seats and makes the seat folding more convenient.

[0075] Furthermore, such as Figure 8As shown, the third locking structure includes a pull rod 233 and a fifth elastic element. The slide rail 232 is provided with a third slot 2321, which extends along the length of the slide rail 232. The pull rod 233 is rotatably connected to the slide plate 231 through a connector 234. The connector 234 is engaged in the third slot 2321 under the action of the fifth elastic element. The second pull cable is connected to the pull rod 233. The unlocking component 82 pulls the second pull cable, causing the pull rod 233 to rotate so that the connector 234 is disengaged from the restriction of the third slot 2321. Specifically, the longitudinal projection shape of the pull rod 233 is U-shaped. Both ends of the pull rod 233 are rotatably connected to two sliding plates 231. The pull rod 233 can simultaneously disengage the connecting pieces 234 at both ends from the third slot 2321. Furthermore, the sliding plate 231 is provided with a guide groove 2311, and the third locking structure is rotatably connected to the guide groove 2311. That is, the pull rod 233 is rotatably connected to the guide groove 2311 via the connecting piece 234, and the connecting piece 234 is engaged in the third slot 2321 under the action of the fifth elastic member. The pull rod 233 and the sliding plate 231 are also provided with a connecting hole 2312, connected by a pin. During the rotation and folding of the backrest assembly 1, the unlocking component 82 pulls the first... The second cable pulls the lever 233, which rotates and is limited by the guide groove 2311. The connector 234 disengages from the third slot 2321. Under the action of the fourth elastic member 24, the slide plate 231 slides along the slide rail 232, and the length of the third slot 2321 determines the movement distance, thereby driving the soft cushion support assembly 21 to move towards the first support member 4. When the seat is unfolded, the lever 233 can be manually rotated, and the connector 234 disengages from the third slot 2321. The soft cushion support assembly 21 can be manually pushed back away from the first support member 4 to reset. When the lever 233 is released, under the action of the fifth elastic member, the connector 234 engages with the third slot 2321 to lock the sliding assembly 23.

[0076] Furthermore, such as Figure 3 and Figure 16As shown, the outrigger assembly also includes a space rod 10 and a movable component 20 fixed to the vehicle floor. The space rod 10 includes a first end 101 and a second end 102. The first end 101 is rotatably connected to the movable component 20 via a ball pin, and the second end 102 is rotatably connected to the seat assembly 2 via a ball pin. The second end 102 is eccentrically positioned on the axis of rotation of the first support member 4 relative to the seat assembly 2. The end of the first support member 4 away from the seat assembly 2 is rotatably connected to the movable component 20 and forms a rotation axis. The first support member 4 can move along the extension direction of the rotation axis via the movable component 20. When the mounting base 22 rotates around the first support member 4, the second end 102 of the space rod 10 is connected to the seat assembly 2 through a ball pin, and can therefore rotate in multiple directions. Since the distance between the second end 102 and the axis of rotation remains unchanged, and the space rod 10 is not telescopic, the first support member 4 and the moving part 20 move in the extension direction of the axis of rotation. The entire seat moves with the first support member 4, making it convenient to put the seat into the placement pit when the placement pit is set on one side in front of the seat.

[0077] Specifically, such as Figure 9 , Figure 10 and Figure 16 As shown, the moving component 20 includes a rotating plate 201, a sliding member 202, and a pneumatic damper 203. One end of the sliding member 202 and the first support member 4 are slidably connected to the rotating plate 201. One end of the pneumatic damper 203 is connected to the sliding member 202, and the other end of the pneumatic damper 203 is connected to the first support member 4. The rotating plate 201 is rotatably connected to the car floor. The rotating plate 201 has a sliding area 2011, where the sliding member 202 and the first support member 4 are slidably connected. A roller 30 is provided on the side of the first support member 4 near the second support member 5, and is rotatably connected to the first support member 4. The roller 30 rolls in the sliding area 2011 during the movement of the first support member 4. A protrusion 2021 is provided on the contact surface between the sliding member 202 and the rotating plate 201, which facilitates smoother sliding between the sliding member 202 and the first support member 4. Both ends of the pneumatic damper 203 are connected to the first support member 4 and the sliding member 202 respectively via ball pins. When the first support member 4 rotates around the end connected to the rotating plate 201 toward the car floor, it can prevent the rotation speed from being too fast, which would cause the entire seat to crash into the car floor and be damaged.

[0078] Furthermore, such as Figures 11 to 13As shown, it also includes a second reset component. The seat cushion assembly 2 includes a fixed bracket 25. The backrest assembly 1 is rotatably mounted on the fixed bracket 25. The drive assembly 81 includes a pusher 811, a rotating component 812, and a first reset component. The pusher 811 is fixedly connected to the backrest assembly 1. The rotating component 812 and the unlocking assembly 82 are rotatably mounted on the fixed bracket 25 and located in the gap between the fixed bracket 25 and the backrest assembly 1. The pusher 811 abuts against the rotating component 812. The output end of the rotating component 812 is drivenly connected to the unlocking assembly 82. The two ends of the first reset component are respectively connected to the rotating component 812 and the fixed bracket 25. The two ends of the second reset component are respectively connected to the fixed bracket 25 and the unlocking assembly 82. The unlocking assembly 82 is provided with a plurality of connecting parts 821 for connecting the pull cable. One end of the floor lock cable and the second cable are connected to the connecting part 821. When the backrest assembly 1 rotates and folds towards the seat cushion assembly 2, the pusher 811, which is fixedly connected to the backrest assembly 1, rotates with the backrest assembly 1 and pushes the rotating part 812 to rotate. The output end of the rotating part 812 drives the unlocking assembly 82 to rotate, thereby pulling the floor lock cable and the second cable connected to the unlocking assembly 82, unlocking the second locking structure and the third locking structure, which facilitates seat folding. In addition, since the rotation axis of the rotating part 812 is parallel to the rotation axis of the unlocking assembly 82 and has a gap... Thus, when the rotating component 812 drives the unlocking component 82 to rotate to the preset position, the unlocking component 82 can disengage from the constraint of the rotating component 812. Under the action of the second reset component, the unlocking component 82 resets, and the ground lock cable and the second cable are no longer stretched, thereby automatically resetting the second locking structure and the third locking structure, automatically locking the second support component 5 and the sliding component 23 without requiring repeated operation by the user. When the seat is unfolded, the pushing component 811 rotates with the backrest assembly 1 and no longer pushes the rotating component 812. The rotating component 812 resets under the action of the first reset component. The unlocking device 8 can unlock the second locking structure and the third locking structure simultaneously without unlocking them one by one, making the seat folding smooth and quick. Under the action of the second reset component, the unlocking component 82 automatically resets during the folding process, no longer stretching the ground lock cable and the second cable, and resetting the second locking structure and the third locking structure, preventing the sliding component 23 from loosening after the seat is folded, which would affect storage. Specifically, the fixed bracket 25 includes a bracket 251 and a fixed frame 252. The bracket 251 is fixedly connected to the fixed frame 252, and the rotating member 812 is rotatably mounted on the bracket 251. The two ends of the first reset member are respectively connected to the bracket 251 and the rotating member 812. The fixed frame 252 is fixedly mounted on the soft cushion support assembly 21. The bracket 251 is also provided with a limiting block 2511 to limit the rotation angle of the rotating member 812, so as to facilitate the reset of the rotating member 812. In addition, the unlocking assembly 82 is also provided with an isolation groove 822 for isolating the ground lock cable and the second cable to prevent entanglement during the pulling of the ground lock cable and the second cable, which would affect the folding of the seat.

[0079] Furthermore, the drive assembly 81 also includes a push rod 813 and a third reset member. The push rod 813 is rotatably mounted on the side of the rotating member 812 away from the push member 811. The rotating member 812 is provided with a limiting member 8121 for limiting the rotation direction of the push rod 813. The unlocking assembly 82 is provided with a protrusion 823. The push rod 813 is drivenly connected to the protrusion 823. The third reset member is used to reset the push rod 813. When the backrest assembly 1 is folded toward the seat cushion assembly 2, the pusher 811 pushes the rotating member 812 to rotate, thereby driving the push rod 813 to rotate. The push rod 813 then pushes the protrusion 823 to rotate the unlocking component 82. When the push rod 813 pushes the unlocking component 82 to a preset position, the push rod 813 disengages from the protrusion 823, and the unlocking component 82 resets under the action of the second reset member. When the backrest assembly 1 is unfolded, the pusher 811 no longer applies force to the rotating member 812. Under the action of the first reset member, the rotating member 812 resets and drives the push rod 813 to rotate. When the rotating member 812 reaches the preset position, the push rod 813 contacts the protrusion 823. Under the action of the protrusion 823 and the limiting member 8121, the push rod 813 rotates in the opposite direction to the rotating member 812 until the push rod 813 no longer contacts the protrusion 823. Under the action of the third reset member, the push rod 813 resets, making it easier to push the unlocking component 82 to rotate again. By setting the limiting member 8121 and the third reset member, it is possible to prevent the push rod 813 from failing to drive the unlocking component 82 due to the reaction force of the unlocking component 82 when it drives the unlocking component 82. Specifically, the first reset member, the second reset member, and the third reset member are all torsion springs, the unlocking component 82 is a rotating body, and the rotating member 812 is provided with a stepped groove 8122 that abuts against the push member 811.

[0080] Furthermore, the unlocking component 82 has a limiting groove 824, and the bracket 251 has a limiting post 2512, which is inserted into the limiting groove 824. When the protrusion 823 is no longer in contact with the push rod 813, the unlocking component 82 resets under the action of the second reset member. To ensure that the backrest assembly 1 rotates to the seat cushion assembly 2 to a preset angle next time, the push rod 813 pushes the protrusion 823, which is inserted into the limiting groove 824 through the limiting post 2512, thus limiting the rotation angle of the unlocking component 82 when it resets.

[0081] Furthermore, such as Figure 14As shown, the angle adjustment structure 3 includes an angle adjuster 31 and a connecting rod assembly 32. The angle adjuster 31 is connected to the rotating shaft 11 of the backrest assembly 1. The connecting rod assembly 32 includes a first connecting rod 321, a second connecting rod 322, a third connecting rod 323, and a third elastic member. The first connecting rod 321 is rotatably mounted on the seat cushion assembly 2. The second connecting rod 322 is rotatably connected to the first connecting rod 321. The third connecting rod 323 is rotatably connected to the second connecting rod 322 and the rotating shaft 11 of the backrest assembly 1. The two ends of the third elastic member are respectively connected to the first connecting rod 321 and the seat cushion assembly 2. The first connecting rod 321 is provided with a gripping end 3211 for hand gripping. Specifically, the angle adjuster 31 is located on one side of the backrest assembly 1 and between the backrest assembly 1 and the fixing frame 252. The connecting rod component 32 is located on the side of the fixing frame 252 away from the backrest assembly 1. The first connecting rod 321 has a mounting part 3212, through which the first connecting rod 321 is rotatably mounted to the fixing frame 252. One end of the third elastic member is connected to the mounting part 3212, and the other end of the third elastic member is connected to the fixing frame 252. The first connecting rod 321 has a guide hole 3213, and the fixing frame 252 has a limiting protrusion 2521 that is inserted into the guide hole. 3213 is used to limit the rotation range of the first link 321. The connection end of the second link 322 and the third link 323 is provided with a push groove 3221. The third link 323 is provided with a connecting post 3231, which is inserted into the push groove 3221. When it is necessary to fold or unfold the backrest assembly 1, pull the grip end 3211 upward to rotate the first link 321, thereby driving the second link 322 to rotate. The push groove 3221 pushes the connecting post 3231 to rotate the third link 323, thereby unlocking the angle adjuster 31 and facilitating the rotation of the backrest assembly 1.

[0082] Among them, such as Figure 15 As shown, the backrest assembly 1 includes a backrest bracket 12, a pivot 11 and two auxiliary mounting plates 13. The two auxiliary mounting plates 13 are respectively mounted on both sides of the backrest bracket 12, and the two ends of the pivot 11 pass through the two auxiliary mounting plates 13 and are rotatably connected to the fixing frame 252.

[0083] Furthermore, such as Figure 3As shown, it also includes a second linkage rod 40, which includes a first rod 401 and a second rod 402 with a sliding groove 4021. One end of the first rod 401 is rotatably connected to the end of the first support 4 that is connected to the seat cushion assembly 2, and the other end of the first rod 401 is slidably connected to the sliding groove 4021. One end of the second rod 402 is rotatably connected to the end of the second support 5 that is away from the seat cushion assembly 2. When the backrest assembly 1 rotates and folds towards the seat cushion assembly 2, the unlocking device 8 pulls the floor lock cable to unlock the second locking structure, thereby releasing the second support member 5 from the lock. When the seat cushion assembly 2 rotates and folds around the first support member 4, since the length of the first linkage rod 7 remains unchanged, the second support member 5 rotates and retracts towards the seat cushion assembly 2 under the action of the first linkage rod 7. The first linkage rod 7 is provided with a limiting hole 71. Through the action of the limiting hole 71, the second support member 5 is well hidden in the seat cushion assembly 2, while the second rod 402 overlaps with the first rod 401 as the second support member 5 rotates. When the seat cushion assembly 2 rotates and unfolds around the first support member 4, under the action of the first linkage rod 7, the second support member 5 rotates and unfolds from the seat cushion assembly 2, and unfolds to the designated position under the limitation of the first rod 401 and the second rod 402, and is locked by the second locking structure.

[0084] Specifically, such as Figure 6 As shown, the second locking structure includes an unlocking rod 6 and a floor lock. The unlocking rod 6 is rotatably connected to the second support member 5. The floor lock cable is connected to the unlocking rod 6 and the floor lock, and the floor lock is used to lock the second support member 5. The floor lock cable pulls the unlocking rod 6 to rotate, thereby releasing the floor lock from the second support member 5. A second slot 223 is provided on the connecting rod 221. The floor lock cable is engaged in the second slot 223, and one end of the floor lock cable is connected to the unlocking rod 6. When the backrest assembly 1 rotates towards the seat cushion assembly 2, the unlocking component 82 pulls the floor lock cable with the rotation of the backrest assembly 1, causing the unlocking rod 6 to rotate, thereby unlocking the second support member 5 from the floor lock.

[0085] The present invention also provides an automobile, including an automobile floor and the aforementioned automobile folding seat, wherein the end of the first support member 4 away from the seat cushion assembly 2 is rotatably disposed on the automobile floor, and the end of the second support member 5 away from the seat cushion assembly 2 can be locked to the automobile floor by a second locking structure.

[0086] The working process of this invention is as follows: Figure 1 , Figures 16 to 18As shown, when the seat is folded and stored, pulling the first link 321 rotates, driving the second link 322, which in turn drives the third link 323 to rotate, thereby unlocking the angle adjuster 31. The backrest assembly 1 begins to rotate towards the seat cushion assembly 2. During this process, the first cable is pulled. When the angle between the backrest assembly 1 and the seat cushion assembly 2 is 80°, the stop 922 moves towards the mounting housing 927, the support 911 loses its support, and rotates towards the backrest assembly 1 under the action of the second elastic element, thus realizing the rotation of the headrest 91. When the headrest assembly 9 is stowed, the pusher 811 contacts and presses the rotating member 812, causing the rotating member 812 to rotate and drive the push rod 813 to rotate. The push rod 813 pushes the protrusion 823 to make the unlocking assembly 82 rotate. When the angle between the backrest assembly 1 and the seat cushion assembly 2 is 45°, the second cable is pulled, causing the pull rod 233 to rotate and disengage the connector 234 from the third slot 2321. Under the action of the fourth elastic member 24, the slide plate 231 slides along the slide rail 232, driving the soft cushion support. The support assembly 21 moves toward the first support member 4; when the angle between the backrest assembly 1 and the seat cushion assembly 2 is 14°, the floor lock cable is pulled, the unlocking lever 6 rotates, thereby unlocking the floor lock, the second support member 5 pops out of the floor lock, and the lock is released. When the push rod 813 rotates to the preset position, the push rod 813 and the protrusion 823 no longer contact each other. Under the action of the second reset member, the unlocking assembly 82 resets, the pull rod 233 is no longer pulled, and under the action of the fifth elastic member, the pull rod 233 resets, and the connecting member 234 is engaged with the third... The slot 2321 and the sliding component 23 are locked. When the angle between the backrest assembly 1 and the seat cushion assembly 2 is 0°, the angle adjuster 31 is locked, and the mounting base 22 rotates around the first support member 4. During the rotation, due to the action of the space rod 10, the entire seat moves in the direction of the rotation axis of the first support member 4 relative to the moving part 20. At the same time, under the action of the first linkage rod 7, the second support member 5 rotates and folds in the direction of the seat cushion assembly 2. When the seat cushion assembly 2 and the first support member 4 coincide, they rotate around the rotation axis and are retracted into the placement pit.

[0087] When unfolding the seat, the entire seat is rotated around the rotation axis and removed from the storage pit. The seat cushion assembly 2 is unfolded around one end of the first support member 4, and under the action of the space rod 10, the entire seat moves in the opposite direction to the direction of movement during storage. Under the action of the first linkage rod 7 and the second linkage rod 40, the second support member 5 moves away from the seat cushion assembly 2. The floor lock is unlocked, locking the second support member 5 and keeping the seat cushion assembly 2 stationary. The first linkage rod 321 is pulled to unlock the angle adjuster 31, and the backrest assembly 1 is rotated and unfolded away from the seat cushion assembly 2. The force applied by the pushing member 811 to the rotating member 812 gradually decreases, and the rotating member 812 is reset under the action of the first reset member. The push rod 813 rotates with the rotating member 812. When the angle between the backrest assembly 1 and the seat cushion assembly 2 is 60°, the push rod 813 and the convex When part 823 contacts, due to the action of the limiting member 8121, the push rod 813 rotates in the opposite direction to the rotation direction of the rotating member 812 until it no longer contacts the protrusion 823 and is reset under the action of the third reset member; when the angle between the backrest assembly 1 and the seat cushion assembly 2 is not less than 80°, the push member 811 no longer applies force to the rotating member 812, and due to the action of the limiting block 2511, the rotating member 812 stops rotating. At this time, the first cable is no longer pulled. The headrest 91 is opened by hand, and the stop member 922 is reset under the action of the first elastic member and abuts against the support member 911 to fix the headrest 91. The pull rod 233 is rotated to disengage the connecting member 234 from the third slot 2321. The soft cushion support assembly 21 is pushed by hand to move away from the first support member 4 to reset. The pull rod 233 is released to lock, and the seat unfolding process is completed.

[0088] In summary, the embodiments of the present invention provide an automobile and its folding seat. When the backrest assembly is rotated towards the seat cushion assembly for storage, the first locking structure, the second locking structure, and the third locking structure can be unlocked. This facilitates the storage of the headrest assembly, the movement of the seat cushion assembly towards the first support member to shorten the turning radius, and the unlocking of the second support member from the floor lock. It also causes the unlocking component to automatically reset and the sliding component to lock, preventing the seat cushion assembly from moving during storage and affecting the storage. Under the action of the space rod and the moving component, the entire seat can be moved to one side, which can accommodate situations where the storage pit is located on one side in front of the seat.

[0089] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several improvements and substitutions without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
