[0043] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. In the embodiments of the present application, the terms "first" and "second" are only used to describe the same or similar features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0044] Please refer to Figure 1 , Figure 1 This is a schematic structural diagram of an embodiment of the present application in which a car seat 200 is connected to a floor 100 of a car via a flip mechanism 300 .

[0045] The vehicle seat 200 includes a backrest 201 and a seat cushion 202. Figure 1 The backrest 201 and the seat cushion 202 shown in the figure are skeleton structures. It can be known that the car seat 200 can also include an exterior surface layer wrapped outside the skeleton structure, a soft filler filled in the exterior surface layer, etc. In addition, the car includes a floor 100, and the car floor 100 includes a floor body 101 and a floor pit 102 that is recessed relative to the floor body 101. The floor pit 102 is recessed downward, and the wall of the floor pit 102 encloses a pit cavity 100a. Figure 1 Schematically showing the pit front wall 1021, the pit rear wall 1022 and the pit bottom wall 1023 of the floor pit 102 distributed along the front-to-back direction. Of course, the floor pit 102 also includes pit walls located on the left and right sides.

[0046] Car Seat 200 Figure 1 The posture in the first state is in a normal state of providing a seat, which can be defined as a first state. In the first state, the car seat 200 is supported by the floor body 101, located above the floor body 101 and the floor pit 102, and the upper and lower parts are also in a Figure 1 The vertical direction is also the Z direction of the car. The front-to-back direction of the car seat 200 defined in the embodiment of the present application is the front-to-back direction of the passengers. Figure 1 The car seat 200 is arranged forward, that is, the passenger faces the front of the car seat after sitting, and the opposite side is the rear. The front-to-back direction of the car seat 200 and the front-to-back direction of the car (the Y direction of the car) can be the same. Of course, the front-to-back direction of the car seat 200 and the front-to-back direction of the car can also be opposite. For example, the car seat 200 can also be arranged toward the rear of the car, and the passenger faces the rear of the car after sitting. The position where the seat cushion 202 and the backrest 201 of the car seat 200 are connected is close to the floor pit 102, and can be located at the pit edge of the floor pit 102, so that it can be flipped into the floor pit 102 by the flipping mechanism 300 and be in the second state.

[0047] The flipping mechanism 300 for realizing the flipping of the vehicle seat 200 is described in detail below.

[0048] You can continue to refer to Figure 2 , Figure 2 for Figure 1 An enlarged schematic diagram of the position of the flip mechanism 300.

[0049] The vehicle seat 200 in this embodiment is connected to the floor 100 via a flip mechanism 300, and the flip mechanism 300 can drive the vehicle seat 200 to flip to switch between a first state and a second state. The flip mechanism 300 includes a flip assembly, Figure 2 Two flip assemblies are shown in the figure, which are defined as a first flip assembly 301 and a second flip assembly 302. The first flip assembly 301 and the second flip assembly 302 are arranged on both sides of the car seat 200, specifically, on the left and right sides of the car seat 200. The left and right directions are the left and right directions of the person sitting on the car seat 200. The left side of the car seat 200 is connected to the floor 100 through the first flip assembly 301, and the right side of the car seat 200 is connected to the floor 100 through the second flip assembly 302. This connection is more reliable. The structures of the first flip assembly 301 and the second flip assembly 302 are exactly the same. Specifically, the first flip assembly 301 and the second flip assembly 302 are not limited to being arranged on Figure 2 The left and right sides of the vehicle seat 200 can be symmetrically arranged along the midline extending along the front-rear direction of the vehicle seat 200 , for example, they can also be arranged below the vehicle seat 200 .

[0050] The structure of the first flip assembly 301 can be further referred to Figures 3 to 5 understand, Figure 3 for Figure 2 An exploded schematic diagram of the position of the first flip assembly 301 of the flip mechanism 300; Figure 4 for Figure 3 The exploded view of the first flip assembly 301 in the figure is in the opposite direction. The structure of the second flip assembly 302 is completely the same as that of the first flip assembly 301. The structure of the second flip assembly 302 can be understood by referring to the first flip assembly 301, and will not be discussed repeatedly.

[0051] The first flip assembly 301 includes a first connector 32, a second connector 34 and a third connector 36, wherein the first connector 32 is used to connect to the floor 100 of the car, and the third connector 36 is used to connect to the car seat 200, that is, the first connector 32 and the third connector 36 are both connected to the second connector 34, and the second connector 34 serves as an intermediate connector. In this embodiment, the first connector 32, the second connector 34 and the third connector 36 are all plate structures, such as sheet metal structures, which have high strength and are conducive to reducing space occupation.

[0052] The first flip assembly 301 further includes a first recliner 33 and a second recliner 35. The first connector 32 and the second connector 34 are connected via the first recliner 33, and the third connector 36 and the second connector 34 are connected via the second recliner 35. The structures of the first recliner 33 and the second recliner 35 are also completely the same.

[0053] You can continue to refer to Figure 5 and Figure 6 understand, Figure 5 for Figure 1 A schematic structural diagram of the first angle adjuster 33 or the second angle adjuster 35 of the middle flip mechanism 300; Figure 6 for Figure 5 A schematic diagram of the structure of the first angle adjuster 33 or the second angle adjuster 35 from another perspective.

[0054] The first angle adjuster 33 and the second angle adjuster 35 both include an inner tooth plate 3a, an outer tooth plate 3b, an eccentric wheel (located inside the angle adjuster, not shown in the figure), a driving member 3d, etc. The inner tooth ring of the inner tooth plate 3a cooperates with the outer tooth ring of the outer tooth plate 3b. When the operating torque acts on the driving member 3d, the inner tooth plate 3a is driven to rotate through the eccentric wheel and the outer tooth plate 3b, that is, the inner tooth plate 3a and the outer tooth plate 3b can rotate relative to each other. In this embodiment, the inner tooth plate 3a of the second angle adjuster 35 is connected to the second connecting member 34, and the outer tooth plate 3b of the second angle adjuster 35 is connected to the third connecting member 36, so as to realize the relative rotation of the second connecting member 34 and the third connecting member 36. Correspondingly, the inner tooth plate 3a of the first angle adjuster 33 is connected to the second connecting member 34, and the outer tooth plate 3b of the second angle adjuster 35 is connected to the first connecting member 32, so as to realize the relative rotation of the second connecting member 34 and the first connecting member 32.

[0055] It can be understood that the structure and working principle of the angle adjuster are prior art and will not be discussed in detail in this embodiment. In addition, the inner tooth plate 3b and the outer tooth plate 3a are two rotating parts that rotate relative to each other. Any one of the two rotating parts is connected to the second connecting member 34, and the other is connected to the first connecting member 32 or the third connecting member 36, so that the second connecting member 34 and the first connecting member 32 or the third connecting member 36 can be rotated relative to each other.

[0056] The flip mechanism 300 in this embodiment further includes a first motor 31 and a second motor 37. The first motor 31 is used to drive the first recliner 33, and the second motor 37 is used to drive the second recliner 35. Specifically, the first motor 31 drives the driving member 3d of the first recliner 33 to rotate, and the second motor 37 drives the driving member 3d of the second recliner 35 to rotate. In this way, the first motor 31 can drive the inner tooth plate 3a and the outer tooth plate 3b of the first recliner 33 to rotate relative to each other, and the second motor 37 can drive the inner tooth plate 3a and the outer tooth plate 3b of the second recliner 35 to rotate relative to each other.

[0057] With this setting, you can continue to refer to Figure 7 and Figure 8 understand, Figure 7 for Figure 1 A schematic diagram of a state in which a backrest 201 and a seat cushion 202 of a vehicle seat 200 are folded; Figure 8 for Figure 7 FIG. 2 is a schematic diagram of a state in which the automobile seat 200 is flipped over to the pit cavity 100 a of the floor pit 102 .

[0058] When flipping is required, the first motor 31 drives the driving member 3d of the first angle adjuster 33 to rotate. Since the first connecting member 32 is connected to the floor 100, specifically, it is relatively fixed to the floor 100, the inner tooth plate 3a of the first angle adjuster 33 is fixed to the floor 100, and the outer tooth plate 3b rotates relatively, which drives the second connecting member 34 to rotate. Figure 2 , 7 As the viewing angle, the second connecting member 34 rotates backward counterclockwise, and the entire car seat 200 and the third connecting member 36 also rotate backward counterclockwise accordingly. The rotation center of the first recliner 33 can be defined as the first rotation center A. At the same time, the second motor 37 drives the second recliner 35 to rotate, and the second recliner 35 drives the third connecting member 36 to rotate. Figure 7 From the perspective of the third connecting member 36, the car seat 200 is flipped backward counterclockwise relative to the second connecting member 34, and the rotation center of the second recliner 35 can be defined as the second rotation center B. It can be seen that the flip assembly in this embodiment has two rotation centers, and the third connecting member 36 rotates around the second rotation center B while also revolving around the first rotation center A until the car seat 200 is flipped and put into the pit.

[0059] In this way, the flipping assembly of the flipping mechanism 300 in this embodiment has a double-joint structure, the first connecting member 32, the first angle adjuster 33 and the second connecting member 34 constitute the first joint, the second connecting member 34, the second angle adjuster 35 and the third connecting member 36 constitute the second joint, so that during the flipping process, the first joint rotates around the first rotation center A, the second joint rotates around the second rotation center B while also revolving around the first rotation center A, the car seat 200 is connected to the second joint, and the flipping speed can be doubled, thereby meeting the requirement of fast flipping. What is particularly important is that the first angle adjuster 33 and the second angle adjuster 35 are introduced in the present embodiment, and the first motor 31 and the second motor 37 do not need to directly drive the second connecting member 34 and the third connecting member 36 to rotate, but the corresponding connecting members are driven to rotate by the angle adjuster. The angle adjuster has a self-locking function, so the first motor 31 and the second motor 37 do not need to bear the self-locking, and the strength requirements for the first motor 31 and the second motor 37 are relatively low. The first motor 31 and the second motor 37 can be relatively miniature motors suitable for automobiles, and the cost of the angle adjuster is relatively low. Compared with the motor specially set with large torque mentioned in the background technology, the flipping mechanism 300 equipped with a angle adjuster can reduce the cost while meeting the flipping function requirements.

[0060] In addition, in this embodiment, the first flip assembly 301 and the second flip assembly 302 are arranged on both sides of the car seat 200. It can be seen that the second flip assembly 302 may not be arranged. For example, the first flip assembly 301 is arranged in the middle position of the car seat 200 in the left-right direction, and the flipping is driven by a set of flip assemblies. However, it is obvious that the support and driving flipping of the car seat 200 are more stable when two sets of flip assemblies are arranged.

[0061] After the car seat 200 in this embodiment is flipped into the pit for storage, the use demand of the space inside the car can be improved. The car seat 200 is, for example, the rear seat of the car, and of course it can also be other seats.

[0062] You can continue to refer to Figure 2 , 6 , and combined with Figures 9 to 11 understand, Fig. 9 for Figure 3 A magnified schematic diagram of the middle A area; Fig.10 for Figure 4 A magnified schematic diagram of the B part; Fig.11 for Figure 3 Schematic diagram of the structure of the first motor 31.

[0063] like Figure 6 As shown, the driving member 3d of the first recliner 33 and the second recliner 35 both have a recliner internal spline 3d1, and the driving member 3d can be provided with a hollow recliner spline shaft 3d2, that is, the recliner spline shaft 3d2 has a through hole, and the wall of the through hole is provided with the recliner internal spline 3d1. In addition, the first motor 31 and the second motor 37 are both provided with motor internal splines. Fig. 9 , 10 As shown, the output end of the second motor 37 has a second motor spline shaft 371, and the second motor spline shaft 371 is also a hollow shaft, and the inner wall of the hollow shaft is provided with a second motor internal spline. Fig.11 In the embodiment, the output end of the first motor 31 has a first motor spline shaft 311, and the first motor spline shaft 311 is a hollow shaft and is provided with a first motor internal spline.

[0064] At this time, the flip mechanism 300 also includes a first transmission rod 303 and a second transmission rod 304, and the first transmission rod 303 and the second transmission rod 304 are both provided with external splines, such as Figure 3 , 4As shown in Figures 9 and 10, one end of the second transmission rod 304 is spline-matched with the inner spline 3d1 of the second recliner 35 of the first flip assembly 301, that is, the second transmission rod 304 can pass through the hollow spline shaft of the driving member 3d of the second recliner 35, and the end of the second transmission rod 304 is also spline-matched with the inner spline of the second motor spline shaft 371 of the second motor 37, so that the second motor 37 can drive the second transmission rod 304 to rotate, and the second transmission rod 304 can drive the driving member 3d of the second recliner 35 to rotate. The other end of the second transmission rod 304 is spline-matched with the inner spline 3d1 of the second recliner 35 of the second flip assembly 302, so that when the second transmission rod 304 rotates, it can also drive the driving member 3d of the second recliner 35 of the second flip assembly 302 to rotate, that is, the second motor 37 can simultaneously drive the driving members 3d of the two second recliners 35 to rotate, and accordingly, it can also simultaneously drive the two third connecting members 36 to rotate. That is to say, in this embodiment, the second motor 37 indirectly drives the driving member 3d of the second recliner 35 to rotate via the second transmission rod 304, thereby simultaneously driving the driving member 3d of the second recliner 35 on the other side to rotate.

[0065] Similarly, the first transmission rod 303 and the second transmission rod 304 are arranged in the same principle. One end of the first transmission rod 303 is splined with the internal spline of the first angle adjuster 33 of the first flip assembly 301, and the end of the first transmission rod 303 is splined with the internal spline of the first motor spline shaft 311 of the first motor 31, so that the first motor 31 can drive the first transmission rod 303 to rotate, and the first transmission rod 303 can drive the driving member 3d of the first angle adjuster 33 to rotate. The other end of the first transmission rod 303 is splined with the internal spline 3d1 of the angle adjuster of the first angle adjuster 33 of the second flip assembly 302, so that when the first transmission rod 303 rotates, it can also drive the driving member 3d of the first angle adjuster 33 of the second flip assembly 302 to rotate, that is, the first motor 37 can simultaneously drive the driving members 3d of the two first angle adjusters 33 to rotate, and accordingly, it can also simultaneously drive the two second connecting members 34 to rotate.

[0066] It can be seen that in the present embodiment, the first motor 31 indirectly drives the driving member 3d of the first angle adjuster 33 to rotate via the first transmission rod 303, and the second motor 37 indirectly drives the driving member 3d of the second angle adjuster 35 to rotate via the second transmission rod 304, so that the driving members 3d of the first angle adjusters 33 on both sides can be driven to rotate by a first motor 31 at the same time, and the driving members 3d of the second angle adjusters 35 on both sides can be driven to rotate by a second motor 37 at the same time. On the basis of setting the flipping components on both sides, the number of motors is reduced, and the structure is more compact.

[0067] Can continue to combine Figure 5 , 6Understand and refer to Fig.12 , Fig.12 for Figure 4 Schematic diagram of the structure of the second connecting member 34.

[0068] The second connecting member 34 is provided with a first limiting hole 34c and a second limiting hole 34d, and the first angle adjuster 33 is provided with a first limiting boss 3a1, and the first limiting boss 3a1 is inserted into the first limiting hole 34c to be transmission-connected with the second connecting member 34, that is, after the first limiting boss 3a1 is inserted into the first limiting hole 34c, the part of the first angle adjuster 33 used to connect with the second connecting member 34 will not be able to rotate relative to the axis of the first angle adjuster 33. In this embodiment, the part where the first angle adjuster 33 and the second connecting member 34 are connected is the inner tooth plate 3a, and the first limiting boss 3a1 can be set on the inner tooth plate 3a, and the first limiting boss 3a1 is protruded along a direction parallel to the axis of the first angle adjuster 33.

[0069] The first limiting boss 3a1 of the second recliner 35 is inserted into the second limiting hole 34d to be transmission-connected with the second connecting member 34, that is, after the first limiting boss 3a1 is inserted into the second limiting hole 34d, the part of the second recliner 35 used to connect with the second connecting member 34 and the second connecting member 34 will not be able to rotate relative to each other around the axis of the second recliner 35. In this embodiment, the part of the second recliner 35 connected with the second connecting member 34 is also the inner tooth plate 3a. The second connecting member 34 and the two recliners are directly plugged in, which is simple to assemble.

[0070] In order to ensure the reliability of the connection between the angle adjuster and the second connecting member 34, so that the second connecting member 34 can stably drive the third connecting member 36 to rotate, and the first connecting member 32 can stably drive the second connecting member 34 to rotate, the first limiting boss 3a1 can be inserted into the first limiting hole 34c and the second limiting hole 34d and then welded and fixed. This plug-in method makes the welding contact area larger and the welding effect more reliable. However, it can be seen that the connection method of the angle adjuster and the second connecting member 34 is not limited to welding. For example, the first limiting boss 3a1 can also be pressed into the first limiting hole 34c and the second limiting hole 34d to be fixed. For another example, the angle adjuster and the second connecting member 34 can also be clamped or connected and fixed by fasteners such as connecting bolts to achieve a transmission connection.

[0071] In addition, if Fig.12As shown, the second connecting member 34 is also provided with a first avoidance hole 34a and a second avoidance hole 34b. The first avoidance hole 34a is used to avoid the driving member 3d of the first recliner 33, and the second avoidance hole 34b is used to avoid the driving member 3d of the second recliner 35. The two recliners of the same flip assembly are arranged relative to each other, that is, the driving members 3d of the first recliner 33 and the second recliner 35 are arranged relative to each other. The two recliners are respectively located on different sides of the second connecting member 34. It can be defined that the second connecting member 34 has a first side and a second side distributed along the rotation axis of the recliner. The first recliner 33 is located on the first side of the second connecting member 34, and the second recliner 35 is located on the second side of the second connecting member 34. In this way, the second connecting member 34 is provided with two groups of avoidance holes and limit holes of the same structure, so as to be connected and fixed with the first recliner 33 and the second recliner 35. Obviously, the rotation axes of the first recliner 33 and the second recliner 35 are parallel to each other and staggered with each other, so as to allow the car seat 200 to have a larger flipping space and reduce flipping interference.

[0072] In addition, the first transmission rod 303 can pass through the corresponding first avoidance hole 34a to be spline-connected with the first motor spline shaft 311 of the first motor 31. At this time, the second connecting member 34 can include a plurality of first limiting holes 34c and a plurality of second limiting holes 34d, the plurality of first limiting holes 34c are arranged around the first avoidance hole 34a, and the plurality of second limiting holes 34d can be arranged around the second avoidance hole 34b. Accordingly, the recliner is provided with a plurality of first limiting bosses 3a1, which can make the transmission connection more reliable.

[0073] Combination Figure 4 and Fig.13 and Fig.14 understand, Fig.13 for Figure 4 A schematic structural diagram of the first connecting member 32; Fig.14 for Fig.13 A schematic structural diagram of the first connecting member 32 from another perspective.

[0074] The first connecting member 32 is provided with a first connecting hole 32a and a second connecting hole 32b, and the first angle adjuster 33 is provided with a second limiting boss 3b1. Figure 5As shown, the second limiting boss 3b1 can be set protruding from the outer tooth plate 3b in a direction parallel to the rotation axis of the angle adjuster, and the second limiting boss 3b1 is inserted into the first connection hole 32a and the second connection hole 32b. In this embodiment, the first angle adjuster 33 and the second angle adjuster 35 are both provided with six second limiting bosses 3b1, and the second connection hole 32b and the second limiting boss 3b1 match, that is, the size of the second limiting boss 3b1 and the second connection hole 32b is roughly equal, and can be welded and fixed after insertion. The first connection hole 32a is a special-shaped hole, and the hole section at each end thereof matches with the two second limiting bosses 3b1, and can match with four second limiting bosses 3b1. The two second connection holes 32b are located on both sides of the first connection hole 32a, and match with the other two second limiting bosses 3b1.

[0075] like Fig.15 As shown, Fig.15 for Figure 4 Schematic diagram of the structure of the third connecting member 36.

[0076] The third connecting member 36 is provided with a third connecting hole 36a and a fourth connecting hole 36b. The third connecting hole 36a is the same as the first connecting hole 32a on the first connecting member 32, and the fourth connecting hole 36b is the same as the second connecting hole 32b of the first connecting member 32, and is used for plugging and matching with the second limiting boss 3b1 of the second angle adjuster 33. Fig.16 In addition, after the second limiting boss 3b1 is inserted into the first connection hole 32a, the second connection hole 32b, the third connection hole 36a and the fourth connection hole 36b, it can also be welded and fixed. Its function is the same as that of the first limiting boss 3a1 and the first limiting hole 34c and the second limiting hole 34d mentioned above, which is to facilitate the connection and fixation. The connection between the angle adjuster and the first connecting member 32 or the third connecting member 36 can also be other fixing methods, which will not be listed one by one.

[0077] Please continue to refer to Fig.14 The first connecting member 32 includes a connecting member body 321, the first motor 31 and the first angle adjuster 33 are installed on the connecting member body 321, and illustratively, the connecting member body 321 is provided with a first connecting portion 325, and the first connecting portion 325 can be a columnar structure. Fig.11 The first motor 31 is provided with a first motor mounting hole 312, and the first connecting portion 325 can be inserted into the first motor mounting hole 312 and connected and fixed to the first motor 31. Figure 3As shown, the third connecting member 36 is provided with a second connecting portion 361, and the second motor 37 has a second motor mounting hole accordingly, and the second connecting portion 361 can be inserted into the second motor mounting hole to mount and fix the second motor 37 to the third connecting member 36. It can be seen that the first motor 31 and the second motor 37 can also be fixed to other positions, for example, the first motor 31 can be directly fixed to the floor 100, and the second motor 37 can be directly fixed to the car seat 200. In comparison, the first motor 31 is fixed to the first connecting member 32, and the second motor 37 is fixed to the third connecting member 36, and the fixation is relatively simple, and there is no need to add a connection structure to the car seat 200 and the floor 100.

[0078] Continue to refer Fig.14 The connecting member body 321 has a flange 322 on one side, the flange 322 and the rotation axis of the angle adjuster can be parallel, and the flange 322 is provided with a first fixing hole 32c, and the first fixing hole 32c is used to connect with the floor 100. Figure 1 As shown, the flange 322 is close to the front pit wall 1021 of the floor pit 102, and can be fixed by fasteners such as connecting bolts passing through the first fixing holes 32c and inserted into the front pit wall 1021, which is convenient to implement. It can be seen that the first connecting member 32 can also be fixed to the floor 100 by other means, such as welding. Fig.15 In the figure, the third connecting member 36 is provided with a second fixing hole 36c, which can be fixed to the car seat 200 by connecting bolts or other fasteners passing through the second fixing hole 36c. Specifically, the seat cushion 202 of the car seat 200 has a square tube 2021, and the square tube 2021 is welded with a mounting plate 2022, and the third connecting member 36 is fixed to the mounting plate 2022.

[0079] Continue to refer Fig.14 , and combined with Fig.16 understand, Fig.16 for Figure 8 FIG. 2 is an enlarged schematic diagram of the position of the second flip assembly 302 after the automobile seat 200 is flipped into the pit.

[0080] The first connector 32 also includes a first limit stop 323 and a second limit stop 324. When the car seat 200 is in the second state, the first limit stop 323 abuts against the third connector 36, and the second limit stop 324 abuts against the second connector 34, that is, after the second connector 34 and the third connector 36 are rotated to the right position, there are corresponding limit stops to stop and limit, so as to prevent the car seat 200 from rotating excessively, and play a good supporting and limiting role. It can be seen that the car seat 200 can also be supported on the pit bottom wall 1023 when it is rotated to the second state. The connector body 321, the flange 322, the first limit stop 323, and the second limit stop 324 can be an integrated structure, for example, the entire plate structure is processed by stamping or other methods to form the first connector 32.

[0081] like Fig.15 As shown, the third connecting member 36 may have a side portion, and the side portion includes an arc segment 362. Figure 1 The arc section 362 is adapted to fit the arc-shaped pit edge of the floor pit 102 of the floor 100. When the car seat 200 is in the first state, the third connecting member 36 is flipped so that its arc section 362 is close to the arc-shaped pit edge, so as to avoid flipping interference and play a better supporting role.

[0082] In addition, in some embodiments, the car seat 200 can be provided with a seat lock 24, which is specifically arranged at the bottom of the seat cushion 202, and the floor 100 is provided with a lock seat 103, which is specifically arranged at the floor body 101. When the car seat 200 is in the first state, the lock seat 103 and the seat lock 24 cooperate to lock, which can further stabilize the state of the car seat 200.

[0083] Look again Figure 1 The car seat 200 is also provided with an angle adjustment mechanism 203, which includes a third angle adjuster 2032 and a third transmission rod 2031. The structure of the third angle adjuster 2032 is the same as that of the first angle adjuster 33 and the second angle adjuster 35, and also includes two rotating parts: an inner tooth plate and an outer tooth plate. The two rotating parts of the third angle adjuster 2032, one connected to the backrest 201, and the other connected to the seat cushion 202, when the driving member of the third angle adjuster 2032 rotates, the backrest 201 and the seat cushion 202 can be driven to rotate relative to each other, so as to adjust the angle of the backrest 202, and the angle adjustment mechanism 203 also drives the third angle adjusters 2032 on both sides at the same time through the third transmission rod 2031. It can be seen that the structures of the first angle adjuster 33, the second angle adjuster 35 and the third angle adjuster 2032 in this embodiment are universal, and there is no need to design the angle adjuster separately, which can improve the universality and reduce the processing design cost.

[0084] The flipping process of the automobile seat 200 in the above embodiment is specifically as follows:

[0085] When the car seat 200 is in the first state, the angle adjustment mechanism 203 is used to adjust the backrest 201 to flip relative to the seat cushion 202 of the car seat 200, so that the two are close to each other and folded to the first state. Figure 7 The status shown;

[0086] Unlocking the seat lock 204 of the vehicle seat 200 and the lock seat 103 on the floor 100 , so that the vehicle seat 200 can rotate relative to the floor 100 ;

[0087] After the first motor 31 and the second motor 37 are powered on, the first motor spline shaft 311 of the first motor 31 rotates, driving the first transmission rod 303 to rotate, and the first transmission rod 303 drives the driving member 3d of the first angle adjuster 33 to rotate, thereby driving the second connecting member 34 to rotate around the first rotation center A;

[0088] The second angle adjuster 35 forming the second rotation center B is connected to the second connecting member 34, so that the second rotation center B rotates around the first rotation center A;

[0089] The second motor spline shaft 371 of the second motor 37 rotates, driving the second transmission rod 304 to rotate, and the second transmission rod 304 drives the driving member 3d of the second recliner 35 to rotate, which drives the third connecting member 36 to rotate around the second rotation center B; thus, the third connecting member 36 rotates around the second rotation center B and simultaneously revolves around the first rotation center A until the car seat 200 is flipped over and put into the pit. Figure 8 As shown;

[0090] After the car seat 200 is flipped into the pit, the second connecting member 34 contacts the first limit stop 323 of the first connecting member 32 to prevent the second connecting member 34 from rotating, and the third connecting member 36 contacts the second limit stop 324 of the first connecting member 32 to prevent the third connecting member 36 from rotating. At this point, the flipping into the pit action is completed.

[0091] When the car seat 200 needs to be flipped from the second state to the first state, that is, it needs to be flipped out of the pit, the first motor 31 and the second motor 37 are started in reverse until the car seat 200 returns to the sitting position of the first state, and then the seat lock 204 of the car seat 200 and the lock seat 103 on the floor 100 are locked and fixed. The angle adjustment mechanism 203 can also be used to adjust the rotation of the backrest 202 to make it at a suitable sitting angle.

[0092] The present application also provides a car, which includes a floor 100, a car seat 200 and a flip mechanism 300. The flip mechanism 300 is the flip mechanism 300 described in any of the above embodiments, and the technical effects are the same, so they will not be discussed repeatedly.

[0093] The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
