Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a seat flipping mechanism and a seat. Background Technology

[0002] When using the rear seats of a car, the seat backs often need to be flipped forward to make it easier to store and hide the seats, expand the space behind the seats, and make it convenient to place goods in the space behind the seats.

[0003] Currently, existing seat flip mechanisms generally work by pressing down on the seat back, causing it to flip and lie flat against the seat cushion. This then rotates the seat relative to the vehicle body, transforming it from a seating position to a stowed position. These mechanisms typically include a locking mechanism that locks the seat in the stowed state. However, the locking mechanism in existing mechanisms only locks the seat in the stowed position. While this frees up the rear space previously occupied by the seat, the stowed seat also occupies front space, resulting in a relatively small increase in cargo space within the vehicle. Utility Model Content

[0004] The purpose of this utility model is to provide a seat flipping mechanism and a seat to solve the problem in the prior art where the seat is locked in the storage state, occupying the front space and resulting in a small increase in the usable space inside the vehicle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The locking member has a first position and a second position. In the first position, the second engaging portion engages with the first engaging portion, and the second locking surface abuts against the first locking surface to lock the turntable and the rotating shaft. In the second position, the second engaging portion separates from the first engaging portion, and the second locking surface separates from the first locking surface to unlock the turntable and the rotating shaft.

[0013] A driving member is connected to the pawl drive, and the driving member is used to drive the pawl to rotate so that the locking member switches between the first position and the second position.

[0014] In some embodiments, a first elastic member is further included, the first elastic member connecting the mounting bracket and the locking member, the first elastic member being used to rotate the locking member to move the second engaging portion away from the first engaging portion.

[0015] In some embodiments, a second elastic element is further included, which connects the mounting bracket to the pawl, and the second elastic element is used to rotate the pawl so that the first locking surface moves away from the second locking surface.

[0016] In some embodiments, the device further includes a lever and a cable, one end of which is connected to the drive member and the other end of which is connected to the lever. The drive member is used to tighten or loosen the cable. The lever is rotatably mounted on the mounting bracket, and the pawl is connected to the lever.

[0017] In some embodiments, the paddle block has a first insertion portion, and the pawl has a second insertion portion, the second insertion portion being inserted into and connected to the first insertion portion.

[0018] In some embodiments, the first engaging portion is a first tooth located on the edge of the turntable, and the second engaging portion is a second tooth located on the locking member. When the locking member is in the first position, the second tooth meshes with the first tooth.

[0019] In some embodiments, a flipping assist component is further included, which is mounted on the mounting bracket and connected to the rotating shaft.

[0020] In some embodiments, the flipping assist component includes a third elastic element, which is sleeved on the rotating shaft. The third elastic element has a first working arm and a second working arm. When the locking member is in the first position, the first working arm and the second working arm respectively abut against the mounting bracket.

[0021] The turntable is sleeved on the rotating shaft, and the turntable has a first limiting arm and a second limiting arm extending along the central axis of the rotating shaft. The first limiting arm is used to abut against the first actuating arm, and the second limiting arm is used to abut against the second actuating arm.

[0022] In some embodiments, the flipping assist component further includes:

[0023] A drive motor is connected to a connector, the drive motor having a power output shaft, the power output shaft being rotatably mounted on the connector and one end of the power output shaft extending out of the connector;

[0024] The first transmission gear is connected to one end of the power output shaft that extends out of the connector;

[0025] The second transmission gear is connected to the mounting bracket and meshes with the first transmission gear.

[0026] This utility model also provides a seat, including a seat body and a seat flipping mechanism as described above, wherein the connecting member of the seat flipping mechanism is connected to the seat body.

[0027] Compared with the prior art, the advantages of this utility model embodiment of a seat flipping mechanism and seat are as follows:

[0028] The seat flipping mechanism of this utility model embodiment includes a mounting frame, a connecting member, a rotating shaft, a pawl, a locking member, and a driving member. One end of the rotating shaft is rotatably connected to the mounting frame, and the other end is fixedly connected to the connecting member. A turntable is connected to the rotating shaft and has a first engaging portion. The pawl and the locking member are rotatably connected to the mounting frame. The pawl has a first locking surface, and the locking member has a second engaging portion and a second locking surface. The driving member is connected to the pawl and drives the pawl to rotate, causing the locking member to switch between a first position and a second position. In the first position, the second engaging portion engages with the first engaging portion, and the second locking surface abuts against the first locking surface, locking the turntable and the rotating shaft, thus locking the seat body. In the second position, the second engaging portion separates from the first engaging portion, and the second locking surface separates from the first locking surface, unlocking the turntable and the rotating shaft, thereby unlocking the seat body and allowing the seat body to rotate. When the drive unit rotates the pawl, the first locking surface abuts against the second locking surface. During the rotation of the pawl, the pawl pushes the locking member to rotate through the abutment of the first and second locking surfaces, causing the second engaging portion of the locking member to gradually approach the first engaging portion until the second engaging portion engages with the first engaging portion, thus locking the locking member and the turntable, thereby locking the rotating shaft and the seat body. When the pawl rotates in the opposite direction, the first locking surface gradually moves away from the second locking surface, the locking member loses the pushing action of the pawl, and the locking member sinks, causing the second engaging portion of the locking member to move away from the first engaging portion until the second engaging portion separates from the first engaging portion, unlocking the connection between the locking member and the turntable, thereby unlocking the rotating shaft and the seat body. This utility model uses a drive unit to rotate the pawl, allowing the locking member to switch between a first position and a second position, making locking and unlocking the turntable and rotating shaft more convenient. This facilitates locking and unlocking the seat body according to usage needs, and makes it easy to lock the seat body in a set position. When the seat body is flipped from the sitting position to the upright position, the pawl is driven by the drive component to rotate, causing the locking component to switch from the second position to the first position. This locks the seat body in the upright position, so that the seat body does not occupy the rear space and frees up the front space, significantly increasing the usable space inside the vehicle.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0043] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0045] See Figures 1-4As shown, this utility model embodiment provides a seat flipping mechanism, including a mounting bracket 10, a connector 20, a rotating shaft 30, a turntable 40, a pawl 50, a locking member 60, and a driving member 70. The mounting bracket 10 is used to connect to the vehicle body; the connector 20 is used to connect to the seat body 100, and the connector 20 and the seat body 100 can be connected by bolts; one end of the rotating shaft 30 is rotatably connected to the mounting bracket 10, so that the rotating shaft 30 can rotate relative to the mounting bracket 10; the other end of the rotating shaft 30 is fixedly connected to the connector 20, so that the rotating shaft 30 can rotate synchronously with the connector 20, and the rotating shaft 30 and the connector 20 can be welded and fixed; the turntable 40 is connected to the rotating shaft 30, and the turntable 40 is provided with a first locking part 401; the pawl 50 is rotatably connected to the mounting bracket 10, and the pawl 50... The locking member 60 has a first locking surface 501; it is rotatably connected to the mounting bracket 10, and has a second engaging portion 601 and a second locking surface 602; the locking member 60 has a first position and a second position. In the first position, the second engaging portion 601 engages with the first engaging portion 401, and the second locking surface 602 abuts against the first locking surface 501 to lock the turntable 40 and the rotating shaft 30; in the second position, the second engaging portion 601 separates from the first engaging portion 401, and the second locking surface 602 separates from the first locking surface 501 to unlock the turntable 40 and the rotating shaft 30; the driving member 70 is connected to the pawl 50 for transmission, and the driving member 70 is used to drive the pawl 50 to rotate so that the locking member 60 switches between the first position and the second position.

[0046] When the drive member 70 drives the pawl 50 to rotate, the first locking surface 501 abuts against the second locking surface 602. During the rotation of the pawl 50, the pawl 50 pushes the locking member 60 to rotate through the abutment of the first locking surface 501 and the second locking surface 602, so that the second engaging part 601 of the locking member 60 gradually moves closer to the first engaging part 401 until the second engaging part 601 engages with the first engaging part 401, thereby locking the locking member 60 and the turntable 40, and thus locking the rotating shaft 30 and the seat body 100. When the pawl 50 rotates in the reverse direction, the first locking surface 501 gradually moves away from the second locking surface 602. The locking member 60 loses the pushing action of the pawl 50, and the locking member 60 sinks, causing the second engaging portion 601 of the locking member 60 to move away from the first engaging portion 401 until the second engaging portion 601 separates from the first engaging portion 401, thus unlocking the connection between the locking member 60 and the turntable 40, thereby unlocking the rotating shaft 30 and the seat body 100. This utility model uses the driving component 70 to drive the pawl 50 to rotate, causing the locking member 60 to switch between the first and second positions, making it more convenient to lock and unlock the turntable 40 and the rotating shaft 30. This facilitates locking and unlocking the seat body 100 according to usage needs, and makes it easy to lock the seat body 100 in a set position. When the seat body 100 is flipped from the sitting position to the upright position, the pawl 50 is driven to rotate by the drive component 70, so that the locking component 60 is switched from the second position to the first position, which can lock the seat body 100 in the upright position. This allows the seat body 100 to not occupy the rear space and free up the front space, thus significantly increasing the usable space inside the vehicle.

[0047] The turntable 40 is locked by engaging the first engaging part 401 and the second engaging part 601. By setting the position of the first engaging part 401 on the turntable 40, the first engaging part 401 can engage with the second engaging part 601 when the turntable 40 rotates to a certain position, thus locking the turntable 40. This makes it convenient to preset the locking position of the turntable 40 and to lock the seat body 100 in the set position.

[0048] See Figure 4 As shown, in some embodiments, the first locking surface 501 is curved and protrudes in a direction away from the center of the pawl 50. The second locking surface 602 is curved and fits the first locking surface 501, and is recessed in a direction close to the locking member 60.

[0049] See Figures 1-4As shown, in some embodiments, the seat flipping mechanism further includes a first elastic element 61. The first elastic element 61 connects the mounting bracket 10 and the locking element 60. The first elastic element 61 is used to rotate the locking element 60, causing the second engaging portion 601 to move away from the first engaging portion 401, thus assisting the locking element 60 in switching from the first position to the second position. When the locking element 60 separates from the first locking surface 501 and the second locking surface 602, and loses the pushing action of the pawl 50, the first elastic element 61 provides assistance for the reset of the locking element 60. Under the elastic force of the first elastic element 61, the locking element 60 rotates and resets relative to the mounting bracket 10, causing the second engaging portion 601 to separate from the first engaging portion 401, thereby unlocking the turntable 40. The first elastic element 61 ensures the smooth reset of the locking element 60, making it convenient for the pawl 50 to rotate again, and for the locking element 60 to be pushed back by the cooperation of the first locking surface 501 and the second locking surface 602. The first elastic element 61 is a torsion spring.

[0050] See Figure 3 As shown, in some embodiments, a first rotating shaft 611 is mounted on the mounting bracket 10. The central axis of the first rotating shaft 611 is parallel to the axial direction of the rotating shaft 30, and the first rotating shaft 611 is rotatable relative to the mounting bracket 10. A first elastic member 61 is sleeved on the first rotating shaft 611. Optionally, the first rotating shaft 611 is a riveting shaft.

[0051] See Figures 1-4 As shown, in some embodiments, the seat flipping mechanism further includes a second elastic element 51. The second elastic element 51 connects the mounting bracket 10 and the pawl 50. The second elastic element 51 is used to rotate the pawl 50 so that the first locking surface 501 moves away from the second locking surface 602. When the drive member 70 drives the pawl 50 to rotate, the second elastic element 51 accumulates elastic potential energy. When it is necessary to unlock the turntable 40 and the shaft 30, the drive member 70 stops providing driving force to the pawl 50, and the pawl 50 rotates in the opposite direction to reset under the elastic force of the second elastic element 51 until the first locking surface 501 separates from the second locking surface 602. By providing the reset force for the pawl 50 through the second elastic element 51, the power loss of the drive member 70 is reduced, saving energy. The second elastic element 51 is a torsion spring.

[0052] See Figure 3 As shown, in some embodiments, a second rotating shaft 511 is mounted on the mounting bracket 10. The central axis of the second rotating shaft 511 is parallel to the axial direction of the rotating shaft 30, and the second rotating shaft 511 is rotatable relative to the mounting bracket 10. A second elastic member 51 is sleeved on the second rotating shaft 511. Optionally, the second rotating shaft 511 is a riveting shaft.

[0053] See Figures 1-4As shown, in some embodiments, the seat flipping mechanism further includes a lever 52 and a cable 53. One end of the cable 53 is connected to the drive member 70, and the other end is connected to the lever 52. The drive member 70 is used to tighten or loosen the cable 53. The lever 52 is rotatably mounted on the mounting bracket 10, and a pawl 50 is connected to the lever 52. When the drive member 70 tightens the cable 53, the cable 53 drives the lever 52 to rotate, and the pawl 50 rotates synchronously with the lever 52, causing the first locking surface 501 to abut against the second locking surface 602. When the pawl 50 rotates, through the cooperation of the first locking surface 501 and the second locking surface 602, it pushes the locking member 60 to rotate, causing the second engaging part 601 to engage with the first engaging part 401, locking the turntable 40. The drive member 70 is a motor. When the drive member 70 releases the cable 53, the lever 52 loses the driving force of the drive member 70. Under the elastic force of the second elastic member 51, the lever 52 rotates in the opposite direction. The lever 52 drives the pawl 50 to rotate synchronously, causing the first locking surface 501 to move away from the second locking surface 602 until the first locking surface 501 and the second locking surface 602 are separated. This causes the locking member 60 to lose the pushing action of the pawl 50. The locking member 60 can then rotate in the opposite direction to reset under the elastic force of the first elastic member 61, causing the first locking part 401 to separate from the second locking part 601, thus unlocking the turntable 40. The lever 52 and the pawl 50 can both be sleeved on the second rotating shaft 511.

[0054] See Figure 5 As shown, in some embodiments, the toggle block 52 has a first insertion portion 5211, and the pawl 50 has a second insertion portion 502. The second insertion portion 502 is inserted into and connected to the first insertion portion 5211, so that the toggle block 52 and the pawl 50 are connected to each other, ensuring that the toggle block 52 and the pawl 50 rotate synchronously. Connecting the toggle block 52 and the pawl 50 by inserting the first insertion portion 5211 and the second insertion portion 502 facilitates the installation and removal of the toggle block 52 and the pawl 50 within the mounting bracket 10. Furthermore, when the pawl 50 wears out due to prolonged use, only the pawl 50 needs to be removed and replaced, reducing maintenance costs. The first insertion portion 5211 is one of a slot or a plug, and the second insertion portion 502 is the other of a slot or a plug, with the slot and plug being compatible.

[0055] See Figure 5As shown, in some embodiments, the lever 52 includes a lever body 521, a first connecting portion 522, and a second connecting portion 523. The lever body 521 is rotatably connected to the frame, specifically, the lever body 521 is sleeved on the second rotating shaft 511. One end of the first connecting portion 522 is connected to the lever body 521, and the other end of the first connecting portion 522 is connected to the second connecting portion 523. The cable 53 is connected to the second connecting portion 523. A first insertion portion 5211 is provided on the lever body 521. The first connecting portion 522 extends along a direction parallel to the rotation axis of the lever body 521, and the second connecting portion 523 extends along a direction perpendicular to the rotation axis of the lever body 521. This connection between the first connecting portion 522 and the second connecting portion 523 forms a clearance space for the pawl 50, facilitating the connection between the cable 53 and the second connecting portion 523 and avoiding interference with the rotation of the pawl 50.

[0056] See Figure 3 and Figure 4 As shown, in some embodiments, the first engaging portion 401 is a first tooth 402 located on the edge of the turntable 40, and the second engaging portion 601 is a second tooth 603 located on the locking member 60. When the locking member 60 is in the first position, the second tooth 603 meshes with the first tooth 402. Through the meshing of the first tooth 402 and the second tooth 603, the locking member 60 and the turntable 40 are locked, thereby locking the rotating shaft 30 and the seat body 100. Using tooth meshing to lock the locking member 60 and the turntable 40 facilitates the engagement of the second engaging portion 601 with the first engaging portion 401 and ensures the stability of the turntable 40 locking. By setting the position of the first gear 402 in the circumferential direction of the turntable 40, when the turntable 40 rotates to a certain position, the first gear 402 can engage with the second gear 603 to lock the turntable 40. This facilitates pre-setting the locking position of the turntable 40 and locking the seat body 100 in the set position. The central angle corresponding to the first gear 402 on the turntable 40 is an acute angle, so that the second gear 603 will only engage with the first gear 402 when the turntable 40 rotates to the point where the first gear 402 is located on the lower side of the turntable 40, by rotating the pawl 50 and the locking member 60. In other embodiments, the first gear 402 can also be evenly distributed along the circumferential direction of the turntable 40 to facilitate locking the turntable 40 according to usage requirements.

[0057] See Figure 6 and Figure 7As shown, in some embodiments, the seat flipping mechanism further includes a flipping assist component 80, which is connected to the rotating shaft 30. The flipping assist component 80 provides assistance for flipping the seat body 100, which can both offset part of the weight of the seat body 100 when the seat body 100 changes from the sitting state to the storage state, so that the seat body 100 can be put into the pit more smoothly, and offset part of the weight of the seat body 100 when the seat body 100 changes from the storage state to the sitting state, thereby reducing the external force required to flip the seat body 100.

[0058] See Figure 6 and Figure 7 As shown, in some embodiments, the flipping assist assembly 80 includes a third elastic element 81, which is sleeved on the rotating shaft 30. The third elastic element 81 has a first actuating arm 811 and a second actuating arm 812. When the locking member 60 is in the first position, the first actuating arm 811 and the second actuating arm 812 abut against the mounting bracket 10, respectively. When the seat body 100 is in a vertical state, the center of gravity of the seat passes vertically through the axis of the rotating shaft 30. At this time, the first actuating arm 811 and the second actuating arm 812 abut against the mounting bracket 10, and the third elastic element 81 does not provide assistance. At this time, the driving member 70 drives the pawl 50 to rotate, and the pawl 50 pushes the locking member 60, so that the second engaging part 601 of the locking member 60 engages with the first engaging part 401, locking the turntable 40, and locking the seat body 100 in a vertical state. The third elastic element 81 is a spring.

[0059] See Figure 6 and Figure 7 As shown, in some embodiments, there are two third elastic elements 81, and correspondingly, there are two first actuating arms 811 and two second actuating arms 812. The first third elastic element 81 is sleeved on the rotating shaft 30, and the second third elastic element 81 is sleeved on the first third elastic element 81.

[0060] See Figure 6 and Figure 7As shown, in some embodiments, the turntable 40 is sleeved on the rotating shaft 30 and rotates synchronously with the rotating shaft 30. The turntable 40 has a first limiting arm 41 and a second limiting arm 42, which extend along the central axis of the rotating shaft 30. The first limiting arm 41 abuts against the first actuating arm 811, and the second limiting arm 42 abuts against the second actuating arm 812. When the seat body 100 is in the sitting state, the first actuating arm 811 abuts against the first limiting arm 41, and the second actuating arm 812 abuts against the mounting bracket 10; when the seat body 100 is in the folded state, the first actuating arm 811 abuts against the mounting bracket 10, and the second actuating arm 812 abuts against the second limiting arm 42. During the seat flipping process, when the seat's center of gravity is not perpendicular to the axis of the rotating shaft 30, the seat body 100 rotates, causing the turntable 40 to rotate via the rotating shaft 30. The turntable 40, through the first limiting arm 41 or the second limiting arm 42, pushes the third elastic element 81 to rotate in the tightening direction, causing the third elastic element 81 to generate a torque in the opposite direction. Thus, during the seat body 100 flipping process, the third elastic element 81 provides the seat body 100 with a torque opposite to the direction of gravity. When flipping the seat body 100 upwards, it assists in the rotation of the seat body 100; when flipping the seat body 100 downwards, it ensures a smooth flipping. A fixing nut is provided at one end of the rotating shaft 30, which prevents the turntable 40 from moving axially along the rotating shaft 30.

[0061] See Figure 6 and Figure 7 As shown, in some embodiments, the mounting bracket 10 includes a mounting base 11 and a mounting frame 12. The mounting base 11 is used to connect to the vehicle body, and the mounting frame 12 is fixed to the mounting base 11. A rotating shaft 30 is rotatably connected to the mounting frame 12. A turntable 40 is located within the mounting frame 12 and is sleeved on the rotating shaft 30. (See reference...) Figures 6-8 As shown, the mounting frame 12 has a first abutment portion 121 and a second abutment portion 122. The first abutment portion 121 abuts against the first abutment arm 811, and the second abutment portion 122 abuts against the second abutment arm 812. The first abutment portion 121 and the second abutment portion 122 are respectively located on opposite sides of the mounting frame 12. The first abutment portion 121 and the second abutment portion 122 are integrally formed with the mounting frame 12. Optionally, the first abutment portion 121 and the second abutment portion 122 can also be components independent of the mounting frame 12. Alternatively, the first abutment portion 121 is integrally formed with the mounting frame 12, and the second abutment portion 122 is fixedly connected to the mounting frame 12.

[0062] See Figure 6 and Figure 7As shown, in some embodiments, the flipping assist assembly 80 further includes a drive motor 82, a first transmission gear 83, and a second transmission gear 84. The drive motor 82 is connected to the connector 20 and has a power output shaft 821. The power output shaft 821 is rotatably mounted on the connector 20, with one end of the power output shaft 821 extending out of the connector 20. The first transmission gear 83 is connected to the end of the power output shaft 821 that extends out of the connector 20. The second transmission gear 84 is connected to the mounting bracket 10, and the first transmission gear 83 meshes with the second transmission gear 84. The drive motor 82 drives the power output shaft 821 to rotate, which in turn drives the first transmission gear 83 to rotate around the second transmission gear 84. The first transmission gear 83 drives the connector 20 to rotate, causing the rotating shaft 30 and the turntable 40 to rotate synchronously with the connector 20. The drive motor 82 provides electric assistance for the flipping of the seat body 100, reducing the external force required for flipping. Furthermore, the drive motor 82 is connected to the connector 20, which facilitates the installation of the drive motor 82 and reduces the space occupied by the drive motor 82 inside the vehicle. For easy disassembly and assembly, the drive motor 82 can be connected to the connector 20 with bolts.

[0063] In some embodiments, the power output shaft 821 is mounted on the connector 20 via a bushing 822, which reduces wear, vibration and noise during the rotation of the power output shaft 821.

[0064] See Figure 1 and Figure 2 As shown, in some embodiments, the seat flipping mechanism further includes a bracket 90, one end of which is connected to the mounting frame 10, and the second transmission gear 84 is fixed to the other end of the bracket 90. The bracket 90 facilitates the connection between the second transmission gear 84 and the mounting frame 10. The bracket 90 is sleeve-shaped, and the second transmission gear 84 is coaxially arranged with the bracket 90. The second transmission gear 84 and the bracket 90 can be welded together, and the bracket 90 and the mounting frame 10 can be welded together to enhance connection stability.

[0065] See Figure 1 and Figure 2 As shown, in some embodiments, the bracket 90 is provided with a retractable wheel 91, which is used to retract the cable of the seat floor lock bracket, facilitating the extension and locking of the seat floor lock bracket and its retraction and concealment. It should be noted that when the seat body 100 is in the seated position, the floor lock locks the seat body 100 to the vehicle floor.

[0066] This utility model also provides a seat, including a seat body 100 and the above-mentioned seat flipping mechanism, wherein the connecting member 20 of the seat flipping mechanism is connected to the seat body 100.

[0067] The working process of this utility model is as follows:

[0068] See Figures 9-11 As shown, when the seat body 100 is changed from a sitting position to an upright position, the seat body 100 is flipped upwards. During the flipping process, the flipping assist component 80 provides flipping assistance to the seat body 100. When the seat body 100 is turned into an upright position, the drive member 70 tightens the pull cable 53. The pull cable 53 pulls the lever 52 and the pawl 50 to rotate against the elastic force of the second elastic member 51, so that the first locking surface 501 abuts against the second locking surface 602. The pawl 50 continues to rotate, and the pawl 50 pushes the locking member 60 to rotate against the elastic force of the first elastic member 61, so that the second engaging part 601 moves closer to the first engaging part 401 until the second engaging part 601 engages with the first engaging part 401, and the drive member 70 stops operating. Locking the turntable 40 by locking the pivot 30 locks the seat body 100 in a vertical position, so that the seat body 100 does not occupy the rear space and frees up the front space, thus significantly increasing the usable space inside the vehicle.

[0069] When the seat body 100 needs to be stored, the pull cable 53 is released in the opposite direction by the drive component 70. The pawl 50 rotates in the opposite direction under the elastic force of the second elastic component 51, causing the first locking surface 501 to move away from the second locking surface 602. The locking component 60 loses the pushing action of the pawl 50 and rotates in the opposite direction under the elastic force of the first elastic component 61, causing the second locking part 601 to move away from the first locking part 401 until the second locking part 601 separates from the first locking part 401. The unlocking turntable 40 is then unlocked, allowing the turntable 40 and the rotating shaft 30 to rotate and the seat body 100 to be flipped over, so that the seat body 100 can be stored in the pit.

[0070] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
