Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a flip mechanism for a car seat and a car. Background Art

[0002] A car consists of a floor and a car seat. Some models have a recessed floor pit, allowing the car seat to be flipped into the pit when the interior space needs to be expanded. Related technical solutions include using a monotonic angle adjuster to drive the car seat to flip, but this is slow and provides a poor user experience. To achieve rapid flipping of the car seat into the pit, related technical solutions use a motor to drive the car seat into the floor pit. However, relying solely on the motor to bear the flipping torque requires excessively high motor torque, making this function difficult to implement with motors suitable for automobiles. Designing a motor specifically for the flipping torque requirement would also be costly. Utility Model Content

[0043] In order to enable those skilled in the art to better understand the technical solutions of this application, the present application is further described in detail below with reference to the accompanying drawings and specific embodiments. In the embodiments of this application, the terms "first" and "second" are only used to describe identical or similar features and are not to 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 structural diagram of an embodiment of the present application in which a car seat 200 is connected to a car floor 100 via a flip mechanism 300 .

[0045] The car seat 200 includes a backrest 201 and a seat cushion 202. Figure 1 The backrest 201 and seat cushion 202 shown in the figure are a skeleton structure. It can be seen that the car seat 200 can also include an exterior surface wrapped around the skeleton structure, a soft filler filled in the exterior surface, etc. In addition, the car includes a floor 100, which 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 shows the pit front wall 1021, the pit rear wall 1022 and the pit bottom wall 1023 distributed along the front-to-back direction of the floor pit 102. 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 middle is in a normal state of providing a ride, which can be defined as a first state. In the first state, the car seat 200 is supported on the floor body 101 and is located above the floor body 101 and the floor pit 102. Figure 1 The vertical direction is also the Z direction of the car. The front-back direction of the car seat 200 defined in the embodiment of the present application is the front-back direction of the passengers. Figure 1 The car seat 200 is positioned forward, meaning that the rear-facing side of the seat faces the front of the car seat, with the opposite side being the rear. The front-to-back direction of the car seat 200 can be the same as the front-to-back direction of the car (the Y direction of the car). Alternatively, the front-to-back direction of the car seat 200 can be opposite to the front-to-back direction of the car. For example, the car seat 200 can be positioned toward the rear of the car, with the rear-facing side facing the rear of the car. The intersection of the seat cushion 202 and backrest 201 of the car seat 200 is located near the floor well 102 and can be positioned at the edge of the floor well 102, allowing the seat to be subsequently flipped into the floor well 102 by the flip mechanism 300 to assume the second position.

[0047] The following is a detailed description of the turning mechanism 300 for turning the vehicle seat 200 .

[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 car seat 200 in this embodiment is connected to the floor 100 via a flip mechanism 300. The flip mechanism 300 can drive the car 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, 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 car seat 200 can be symmetrically arranged along the center line extending along the front-to-back direction of the car seat 200, for example, they can also be arranged below the car 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 view of the position of the first flip assembly 301 of the flip mechanism 300; Figure 4 for Figure 3 The structure of the second flip assembly 302 is exactly the same as that of the first flip assembly 301 , and the structure of the second flip assembly 302 can be understood with reference to the first flip assembly 301 , and will not be discussed again.

[0051] The first flip assembly 301 includes a first connector 32, a second connector 34, and a third connector 36. The first connector 32 is used to connect to the vehicle floor 100, and the third connector 36 is used to connect to the vehicle seat 200. In other words, both the first connector 32 and the third connector 36 are connected to the second connector 34, with the second connector 34 serving 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 provide high strength and reduce space usage.

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

[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 structural diagram of the first angle adjuster 33 or the second angle adjuster 35 from another perspective.

[0054] Each of the first and second recliners 33 and 35 includes an inner toothed plate 3a, an outer toothed plate 3b, an eccentric (located inside the recliner, not shown), and a drive member 3d. The inner ring gear of the inner toothed plate 3a cooperates with the outer ring gear of the outer toothed plate 3b. When operating torque is applied to the drive member 3d, the inner toothed plate 3a is driven to rotate via the eccentric and outer toothed plate 3b, thereby enabling relative rotation between the inner and outer toothed plates 3a and 3b. In this embodiment, the inner toothed plate 3a of the second recliner 35 is connected to the second connecting member 34, while the outer toothed plate 3b of the second recliner 35 is connected to the third connecting member 36, thereby enabling relative rotation between the second and third connecting members 34 and 36. Accordingly, the inner toothed plate 3a of the first recliner 33 is connected to the second connecting member 34, while the outer toothed plate 3b of the second recliner 35 is connected to the first connecting member 32, thereby enabling relative rotation between the second and first connecting members 34 and 32.

[0055] It is understood that the structure and operating principle of the recliner are prior art and will not be further discussed in this embodiment. Furthermore, the inner tooth plate 3b and the outer tooth plate 3a are two rotating components that rotate relative to each other. If one of these rotating components is connected to the second connecting member 34 and the other to the first connecting member 32 or the third connecting member 36, relative rotation between the second connecting member 34 and the first connecting member 32 or the third connecting member 36 can be achieved.

[0056] The tilting mechanism 300 in this embodiment also 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, while the second motor 37 drives the driving member 3d of the second recliner 35. In this way, the first motor 31 can drive the inner and outer toothed plates 3a, 3b of the first recliner 33 to rotate relative to each other, while the second motor 37 can drive the inner and outer toothed plates 3a, 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 car seat 200 with a backrest 201 and a seat cushion 202 folded; Figure 8 for Figure 7 FIG. 2 is a schematic diagram of a state in which the car 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 recliner 33 to rotate. Since the first connecting member 32 is connected to the floor 100, specifically fixed relative to the floor 100, the inner tooth plate 3a of the first recliner 33 is fixed to the floor 100, and the outer tooth plate 3b rotates relative to the floor 100, 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 this perspective, the third connector 36 drives the car seat 200 to flip backward counterclockwise relative to the second connector 34. The rotation center of the second recliner 35 can be defined as the second rotation center B. As can be seen, the flip assembly in this embodiment has two rotation centers. The third connector 36 rotates around the second rotation center B while simultaneously revolving around the first rotation center A until the car seat 200 is flipped and placed into the car seat.

[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, and the second joint rotates around the second rotation center B while also revolving around the first rotation center A. When the car seat 200 is connected to the second joint, the flipping speed can be doubled, thereby meeting the requirements of fast flipping. What is particularly important is that the first angle adjuster 33 and the second angle adjuster 35 are introduced in this embodiment. 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. Instead, 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 function. The strength requirements of 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 low. Compared with the motor specially set with high 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] Furthermore, in this embodiment, the first and second flip assemblies 301, 302 are disposed on either side of the car seat 200. However, it is apparent that the second flip assembly 302 can be omitted. For example, the first flip assembly 301 can be disposed in the middle of the car seat 200 in the left-right direction, and a single set of flip assemblies can be used to drive the flipping of the car seat 200. However, it is clear that the provision of two sets of flip assemblies provides more stable support and driving of the flipping of the car seat 200.

[0061] After the car seat 200 in this embodiment is flipped into the pit for storage, the use demand of the space in 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, Figure 9 for Figure 3 A magnified schematic diagram of part A in the middle; Figure 10 for Figure 4 A magnified schematic diagram of part B in the middle; Figure 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 an inner recliner spline 3d1. 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 inner recliner spline 3d1. In addition, the first motor 31 and the second motor 37 are both provided with motor inner splines. Figure 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. Figure 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 with a first motor internal spline.

[0064] At this time, the turnover mechanism 300 further includes a first transmission rod 303 and a second transmission rod 304, and both the first transmission rod 303 and the second transmission rod 304 are 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-fitted with the inner spline 3d1 of the recliner 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-fitted with the inner spline of the second motor spline shaft 371 of the second motor 37. In this way, 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-fitted with the inner spline 3d1 of the recliner of the second recliner 35 of the second flip assembly 302. 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, 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 configured in the same manner. One end of the first transmission rod 303 engages with the internal spline of the first recliner 33 of the first flip assembly 301. This end of the first transmission rod 303 also engages with the internal spline of the first motor spline shaft 311 of the first motor 31. Thus, the first motor 31 can drive the first transmission rod 303 to rotate, which in turn drives the driving member 3d of the first recliner 33 to rotate. The other end of the first transmission rod 303 engages with the internal spline 3d1 of the first recliner 33 of the second flip assembly 302. As the first transmission rod 303 rotates, it also drives the driving member 3d of the first recliner 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 recliners 33 to rotate, and accordingly, can also simultaneously drive the two second connecting members 34 to rotate.

[0066] It can be seen that in this embodiment, the first motor 31 indirectly drives the driving member 3d of the first angle adjuster 33 to rotate through the first transmission rod 303, and the second motor 37 indirectly drives the driving member 3d of the second angle adjuster 35 to rotate through 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 at the same time by a first motor 31, and the driving members 3d of the second angle adjusters 35 on both sides can be driven to rotate at the same time by a second motor 37. On the basis of providing flip 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 Figure 12 , Figure 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 each other around 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 achieve driving connection with the second connecting member 34. Specifically, after the first limiting boss 3a1 is inserted into the second limiting hole 34d, the portion of the second recliner 35 that connects to the second connecting member 34 cannot rotate relative to the second connecting member 34 about the axis of the second recliner 35. In this embodiment, the portion connecting the second recliner 35 to the second connecting member 34 is also the internally toothed plate 3a. The second connecting member 34 and the two recliners are directly plugged into each other, simplifying assembly.

[0070] To ensure the reliability of the connection between the recliner and the second connecting member 34, so that the second connecting member 34 can stably drive the third connecting member 36 for rotation, and the first connecting member 32 can stably drive the second connecting member 34 for rotation, the first limiting boss 3a1 can be inserted into the first limiting hole 34c and the second limiting hole 34d and then welded to secure it. This plug-in connection method provides a larger welding contact area and a more reliable welding effect. However, it can be understood that the connection method of the recliner and the second connecting member 34 is not limited to welding. For example, the first limiting boss 3a1 can also be press-fitted into the first limiting hole 34c and the second limiting hole 34d for securement. For another example, the recliner and the second connecting member 34 can also be connected and secured by a snap connection or by fasteners such as connecting bolts to achieve a transmission connection.

[0071] In addition, if Figure 12As shown, the second connecting member 34 is further 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 tilting assembly are arranged opposite each other, that is, the driving members 3d of the first recliner 33 and the second recliner 35 are arranged opposite each other. The two recliners are located on different sides of the second connecting member 34. This can be defined as the second connecting member 34 having a first side and a second side distributed along the recliner's rotation axis. 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. This arrangement provides two sets of avoidance holes and stop holes with the same structure for secure connection with the first and second recliners 33, 35. Clearly, the rotation axes of the first and second recliners 33, 35 are parallel and staggered, allowing the car seat 200 to have a larger tilting space and reducing tilting interference.

[0072] Furthermore, the first transmission rod 303 can pass through the corresponding first avoidance hole 34a to be spline-connected to the first motor spline shaft 311 of the first motor 31. In this case, 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] Combine Figure 4 and Figure 13 and Figure 14 understand, Figure 13 for Figure 4 A schematic structural diagram of the first connecting member 32; Figure 14 for Figure 13 A 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 provided protruding from the outer tooth plate 3b in a direction parallel to the rotation axis of the recliner. The second limiting boss 3b1 is inserted into the first connecting hole 32a and the second connecting hole 32b. In this embodiment, the first recliner 33 and the second recliner 35 are both provided with six second limiting bosses 3b1. The second connecting holes 32b and the second limiting bosses 3b1 match, that is, the second limiting bosses 3b1 and the second connecting holes 32b are of approximately equal size and can be welded together after insertion. The first connecting hole 32a is a special-shaped hole, and the hole section at each end of the hole mates with two second limiting bosses 3b1, which can match four second limiting bosses 3b1. The two second connecting holes 32b are located on either side of the first connecting hole 32a and mate with the other two second limiting bosses 3b1.

[0075] like Figure 15 As shown, Figure 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. It is used for plugging and matching with the second limiting boss 3b1 of the second adjuster 33. Figure 16 In addition, after the second limiting boss 3b1 is inserted into the first connecting hole 32a, the second connecting hole 32b, the third connecting hole 36a, and the fourth connecting 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 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 Figure 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, which can be a columnar structure. Figure 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 connector 36 is provided with a second connecting portion 361, and the second motor 37 correspondingly has a second motor mounting hole. The second connecting portion 361 can be inserted into the second motor mounting hole to secure the second motor 37 to the third connector 36. It can be seen that the first motor 31 and the second motor 37 can also be secured to other locations. For example, the first motor 31 can be directly secured to the floor 100, and the second motor 37 can be directly secured to the car seat 200. In comparison, securing the first motor 31 to the first connector 32 and the second motor 37 to the third connector 36 is relatively simple, without requiring additional connection structures to the car seat 200 or the floor 100.

[0078] Continue to refer Figure 14 The connecting member body 321 has a flange 322 on one side. The flange 322 and the rotation axis of the recliner can be parallel. The flange 322 is provided with a first fixing hole 32c. The first fixing hole 32c is used to connect with the floor 100. Figure 1 As shown, the flange 322 is abutted against 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. This method is relatively convenient for fixing. It is understood that the first connecting member 32 can also be fixed to the floor 100 by other means, such as welding. Figure 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 passing a fastener such as a connecting bolt 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 Figure 14 , and combined with Figure 16 understand, Figure 16 for Figure 8 FIG. 2 is an enlarged schematic diagram of the position of the second flip assembly 302 after the car seat 200 is flipped into the pit.

[0080] The first connector 32 also includes a first stopper 323 and a second stopper 324. When the car seat 200 is in the second position, the first stopper 323 abuts the third connector 36, and the second stopper 324 abuts the second connector 34. That is, after the second connector 34 and the third connector 36 are rotated to their proper positions, the corresponding stopper acts as a stopper to prevent the car seat 200 from excessively rotating, providing a good support and limit effect. It can be seen that the car seat 200 can also be supported by the pit bottom wall 1023 when rotated to the second position. The connector body 321, flange 322, first stopper 323, and second stopper 324 can be an integrated structure, for example, the first connector 32 can be formed by stamping a single plate structure.

[0081] like Figure 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 362 is adapted to fit the arcuate edge of the floor well 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 arcuate section 362 abuts against the arcuate edge, thereby avoiding flipping interference and providing better support.

[0082] In addition, in some embodiments, the car seat 200 can be provided with a seat lock 24, which is specifically provided at the bottom of the seat cushion 202, and the floor 100 is provided with a lock seat 103, which is specifically provided 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 recliner 2032 and a third transmission rod 2031. The structure of the third recliner 2032 is the same as that of the first and second recliners 33 and 35, and also includes two rotating components: an inner tooth plate and an outer tooth plate. The two rotating components of the third recliner 2032 are connected to the backrest 201 and the seat cushion 202, respectively. When the driving member of the third recliner 2032 rotates, it can drive the backrest 201 and the seat cushion 202 to rotate relative to each other, thereby adjusting the angle of the backrest 202. The angle adjustment mechanism 203 also uses the third transmission rod 2031 to simultaneously drive the third recliners 2032 on both sides. Therefore, the first, second, and third recliners 33, 35, and 2032 in this embodiment have a common structure, eliminating the need for separate recliner designs, thereby improving versatility and reducing processing and design costs.

[0084] The flipping process of the car 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 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 car seat 200 and the lock seat 103 on the floor 100 so that the car 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. The first transmission rod 303 drives the driving member 3d of the first recliner 33 to rotate, which drives 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. 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. As a result, 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. 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 backrest 202 to rotate so that it is 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 again.

[0093] The above is only a preferred embodiment 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.
