For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] Reference Figures 1 to 10 , shows a schematic structural diagram of a seat cushion assembly according to an embodiment of the present application, wherein the seat cushion assembly may specifically include: a bracket 10, a rotating connecting rod 20, a seat belt buckle 30 and a connecting member 40;

[0042] The rotating link 20 and the safety belt buckle 30 are respectively arranged on the bracket 10, and the rotating link 20 and the safety belt buckle 30 are respectively rotatably connected to the bracket 10, one end of the connecting member 40 is connected to the rotating link 20, and the other end of the connecting member 40 is rotatably connected to the safety belt buckle 30;

[0043] The rotating link 20 rotates relative to the bracket 10 to drive the connecting member 40 to move, and the connecting member 40 drives the safety belt buckle 30 to rotate relative to the bracket 10 .

[0044] In the embodiments of the present application, Figure 3As shown, when the seat is flipped and adjusted, the rotating link 20 rotates. Since one end of the connecting member 40 is connected to the rotating link 20, the other end of the connecting member 40 is rotationally connected to the safety belt buckle 30, that is, the connecting member 40 is connected between the rotating link 20 and the safety belt buckle 30. Therefore, the rotation of the rotating link 20 drives one end of the connecting member 40 to move, and the other end of the connecting member 40 drives the safety belt buckle 30 to rotate, so that the rotation of the rotating link 20 drives the safety belt buckle 30 to rotate at the same or similar angle through the connecting member 40, and realizes the synchronous linkage between the rotating link 20 and the safety belt buckle 30. In this way, since the safety belt buckle 30 realizes synchronous rotation when the seat is flipped, specifically, the backrest of the seat can be connected to the rotating link 20, and the rotating link 20 drives the rotating link 20 to rotate when the backrest is flipped, and the rotating link 20 drives the safety belt buckle 30 to rotate through the connecting member 40. In addition, the backrest can also be connected to the rotating connecting rod 20 through other structures such as a rotating shaft, etc. There are many relatively mature methods in the prior art, and the embodiments of the present application are not limited to this. In this way, the backrest is prevented from abutting against the safety belt buckle 30 when folded, reducing the wear on the outer surface of the safety belt buckle 30 and the backrest, increasing the service life of the safety belt buckle 30, and also making the backrest have a better appearance.

[0045] Specifically, in the embodiment of the present application, when the seat needs to be flipped and adjusted, the rotating link 20 of the seat cushion assembly rotates relative to the bracket 10, and cooperates with the rotation of the seat back relative to the seat cushion assembly to realize the flipping function of the seat. For example, the rotating link 20 can include a first link 21 and a second link 22, one end of the first link 21 can be rotatably connected to the bracket 10 through a rotating shaft, and the other end of the first link 21 can be rotatably connected to one end of the second link 22 through a transverse tube 23. Specifically, the sleeve can be covered on the outer periphery of the first link 21, the second link 22 and the transverse tube 23, so that the sleeve is supported by the first link 21, the second link 22 and the transverse tube 23. When the seat is flipped and adjusted, the backrest rotates relative to the seat cushion assembly, and the first link 21 rotates and drives the second link 22 to rotate, so that the seat cushion assembly cooperates with the backrest to realize the flipping adjustment of the seat.

[0046] For example, in an embodiment of the present application, the other end of the second connecting rod 21 can be slidably connected to the bracket 10 via an adapter plate 24, that is, one end of the adapter plate 24 is rotatably connected to the other end of the second connecting rod 22, and the bracket 10 can be provided with a slide groove, and the other end of the adapter plate 24 can be slidably connected to the slide groove of the bracket 10 via a slider, so that the first connecting rod 21, the second connecting rod 22, the adapter plate 24 and the bracket 10 form a four-bar linkage to realize the rotation adjustment of the seat cushion assembly.

[0047] In the embodiment of the present application, specifically, the bracket 10 can be fixedly installed on the bottom structure of the vehicle body. For example, the bracket 10 can be provided with an opening so that according to the specific setting positions of the connecting member 40, the rotating link 20 and the seat belt buckle 30, the connecting member 40 can be connected to the rotating link 20 and the seat belt buckle 30 by passing through the opening.

[0048] For example, in an embodiment of the present application, the bracket 10 may include a first side panel and a second side panel that are arranged in opposite directions, the rotating link 20 may be connected to a side of the first side panel away from the second side panel, the safety belt buckle 30 may be connected to a side of the second side panel away from the first side panel, the first side panel may be provided with a first opening, the second side panel may be provided with a second opening, one end of the connecting member 40 is passed through the first opening and connected to the rotating link 20, and the other end of the connecting member 40 is passed through the second opening and connected to the safety belt buckle 30.

[0049] In addition, the rotating link 20 may be connected to a side of the first side panel close to the second side panel, the safety belt buckle 30 may be connected to a side of the second side panel close to the first side panel, the connecting member 40 may be connected between the rotating link 20 and the safety belt buckle 30, and the connecting member 40 may be located between the first side panel and the second side panel, and there is no need to set openings on the first side panel and the second side panel. The specific arrangement of the bracket 10, the rotating link 20, and the safety belt buckle 30 may not be limited in the embodiment of the present application.

[0050] Optionally, in the embodiment of the present application, Figure 3 As shown, the seat cushion assembly may also include a plurality of transverse tubes 23, which are arranged at intervals and may be connected to the bracket 10 and the rotating connecting rod 20 respectively, and the transverse tubes 23 extend in the horizontal direction, which may provide a good support to the cushion sleeve wrapped around the periphery of the seat cushion assembly, so that the seat cushion assembly has a good structural stability. In this way, the transverse tubes 23 also provide a good support to the seat cushion assembly along the width direction of the vehicle. It should be noted that the transverse tubes 23 belong to the prior art, and the specific type of the transverse tubes 23 may not be limited in the embodiments of the present application.

[0051] In the embodiment of the present application, for example, the connecting member 40 can be a steel rope or a steel wire, so that the connecting member 40 has a good pulling force on the safety belt buckle 30, and it is also convenient to bend and wrap the connecting member 40 according to the actual spatial layout to facilitate installation, thereby improving the convenience of assembly.

[0052] Optionally, in some embodiments of the present application, the seat cushion assembly may further include a compensator, which is connected to the connecting member 40. For example, the compensator is sleeved on the outer periphery of a portion of the connecting member 40, and the compensator may be fixed to the bracket 10 by a fixing member (such as a mushroom buckle or a snap buckle, etc.). The compensator may amplify or reduce or delay the transmission of the connecting member 40 from the rotating link 20 to the safety belt buckle 30, etc., so that the rotation of the safety belt buckle 30 and the rotating link 20 has a better synchronization effect. The compensator has a relatively wide and mature application in the prior art and has a variety of types. The working principle and structure of the compensator are not described in detail in this application.

[0053] In the embodiment of the present application, optionally, the cushion assembly further comprises a connecting block 50, and the rotating connecting rod 20 is provided with a protruding stopper 51; the connecting block 50 is connected to the bracket 10 by rotation close to the rotating connecting rod 20, the stopper 51 protrudes toward the connecting block 50 and abuts against the connecting block 50, and one end of the connecting member 40 is connected to the connecting block 50; the rotating connecting rod 20 rotates, so that the stopper 51 drives the connecting block 50 to rotate, and the connecting block 50 drives the connecting member 40 to move. In this way, a relatively reliable connection between the rotating connecting rod 20 and the connecting member 40 is achieved through the connecting block 50, and there is no need to make a major change to the original structure of the rotating connecting rod 20. When the rotating connecting rod 20 rotates, the stopper 51 on the rotating connecting rod 20 moves simultaneously, and because the stopper 51 abuts against the connecting block 50, the stopper 51 drives the connecting block 50 to rotate relative to the bracket 10, and then the connecting block 50 drives the connecting member 40 to move. For example, in the embodiment of the present application, a card slot can be provided on the connecting block 50, and the stopper 51 can abut against the card slot. A snap-fit ​​hole may also be provided on the connection block 50 , and the stopper 51 may be embedded in the snap-fit ​​hole. The embodiment of the present application does not limit the specific connection method between the connection block 50 and the stopper 51 .

[0054] Optionally, in the embodiment of the present application, Figure 5As shown, the connecting member 40 is a connecting strip, and the connecting block 50 is provided with a fixing groove and a guide groove 52 connected to the fixing groove; one end of the connecting strip is provided with a first fixing portion 41 and a first transition portion 42 connected to the first fixing portion 41, the first fixing portion 41 is clamped in the fixing groove, and the first transition portion 42 is embedded in the guide groove 52. In this way, by clamping the first fixing portion 41 in the fixing groove, a more reliable connection between the connecting member 40 and the connecting block 50 is achieved, and the first transition portion 42 is embedded in the guide groove 52, so that one end of the connecting strip is extended along the guide groove 52, so that the connecting member 40 and the connecting block 50 have a larger connection area, and a better fitting effect is achieved. It is avoided that the connecting strip is directly connected to the connecting block 50, which is easy to cause fracture damage due to stress concentration during movement. In this way, the connecting block 50 and the rotating connecting rod 20 can be rotatably connected to the bracket 10 of the seat cushion assembly through the rotating shaft, and the connecting block 50 is driven by the stop block 51, which is easy to assemble. There is no need to connect the connecting block 50 to the rotating connecting rod 20 through welding or other processes, which also simplifies the manufacturing process of the seat cushion assembly.

[0055] In the embodiment of the present application, optionally, Figure 5 and Figure 6 as well as Figure 7 As shown, the seat cushion assembly further includes a first fixing plate 60 and a fixing tube 61. The first fixing plate 60 is connected to a position on the bracket 10 close to the connecting block 50. The fixing tube 61 is clamped to the first fixing plate 60, and the connecting member 40 is slidably connected to the fixing tube 61. That is, the connecting strip can extend from the fixing tube 61, and then be wound around the guide groove 52 of the connecting block 50, and the first fixing portion 41 at the end of the connecting strip is clamped in the fixing groove, so as to achieve a more reliable connection between the connecting member 40 and the connecting block 50. In this way, the position of the connecting member 40 close to the connecting block 50 is fixed by the first fixing plate 60, so that the connecting member 40 is better supported while moving along the axial direction of the fixing tube 61, avoiding interference between the connecting member 40 and other components in the vehicle, such as the cross tube 23, so that the end of the connecting member 40 close to the connecting block 50 has better connection stability.

[0056] Optionally, in the embodiment of the present application, the cushion assembly further comprises a rotating shaft, the rotating shaft is connected to the bracket 10, and the rotating connecting rod 20 and the connecting block 50 are both rotatably connected to the rotating shaft. In this way, the rotating connecting rod 20 and the connecting block 50 are rotatably connected to the bracket 10 more flexibly through the rotating shaft, and the stopper 51 of the rotating connecting rod 20 drives the connecting block 50 to rotate, which can achieve a better synchronization effect.

[0057] In the embodiment of the present application, optionally, Figure 4As shown, the safety belt buckle 30 includes a buckle 31 and a mounting plate 32 connected to the buckle 31, the mounting plate 32 is rotatably connected to the bracket 10, the mounting plate 32 is provided with a mounting hole 33, and the other end of the connecting member 40 is connected to the mounting hole 33. In this way, the safety belt buckle 30 fixes the safety belt through the buckle 31, the safety belt buckle 30 and the bracket 10 are rotatably connected through the mounting plate 32, and the mounting plate 32 is provided with the mounting hole 33, and the other end of the connecting member 40 and the safety belt buckle 30 are more reliably connected through the mounting hole 33.

[0058] For example, in the embodiment of the present application, a protrusion may be provided at one end of the mounting plate 32 away from the buckle 31, and the mounting hole 33 may be provided at the protrusion, and the protrusion provides a setting space for the mounting hole 33. The other end of the connector 40 may be inserted into the mounting hole 33, and the other end of the connector 40 may also be snap-connected to the mounting hole 33 to achieve a relatively stable and reliable connection between the connector 40 and the mounting plate 32. The embodiment of the present application does not limit the specific connection method between the other end of the connector 40 and the mounting hole 33.

[0059] Optionally, in the embodiment of the present application, Figure 8 As shown, the seat cushion assembly further includes a second fixing plate 70 and a guide member 80. The second fixing plate 70 is connected to the bracket 10 at a position close to the mounting plate 32, and the guide member 80 is connected to the second fixing plate 70. The connecting member 40 is a connecting strip, and the other end of the connecting strip is provided with a second fixing portion 43 and a second transition portion 44 connected to the second fixing portion 43. The second fixing portion 43 is connected to the mounting hole 33, and the second transition portion 44 passes through the guide member 80 and is clamped to the second fixing plate 70. In this way, the second fixing plate 70 is used to fix the position of the connecting member 40 close to the mounting plate 32 of the safety belt buckle 30, so that the position of the connecting member 40 close to the mounting plate 32 is better supported, and the interference between the connecting member 40 and other components in the vehicle is avoided, so that the end of the connecting member 40 close to the safety belt buckle 30 has better connection stability.

[0060] Furthermore, the installation of the second transition portion 44 of the connecting member 40 is guided by the guide member 80, so that the other end of the connecting member 40 is smoothly connected to the mounting plate 32 of the safety belt buckle 30. In addition, the second transition portion 44 is embedded in the guide member 80, so that the guide member 80 covers at least part of the second transition portion 44, and also protects the second transition portion 44, so as to prevent the second transition portion 44 of the connecting member 40 from being easily damaged by collision and friction of other structures. For example, the guide member 80 can be made of plastic or metal, and the specific material of the guide member 80 is not limited in the embodiment of the present application.

[0061] In the embodiment of the present application, optionally, Figure 6As shown, the seat cushion assembly also includes a reset elastic member 90, one end of which is connected to the mounting plate 32, and the other end of which is connected to the bracket 10. In this way, the reset elastic member 90 can provide a more reliable return driving force for the reset movement of the seat belt buckle 30. Specifically, when the seat is flipped and folded, the connecting member 40 can drive the mounting plate 32 to rotate counterclockwise relative to the bracket 10, and the reset elastic member 90 is respectively connected to the mounting plate 32 and the bracket 10. The mounting plate 32 drives the reset elastic member 90 to rotate, and the reset elastic member 90 is subjected to compression force or tension force to generate elastic force, which has a tendency to drive the mounting plate 32 to rotate clockwise relative to the bracket 10. Then, when the seat is switched from the folded state to the opened state, the compression force on the reset elastic member 90 disappears, and the reset elastic member 90 drives the mounting plate 32 to rotate clockwise relative to the bracket 10 under the action of the elastic force, so that the mounting plate 32 returns to the initial position. For example, the reset elastic member 90 can be a torsion spring, and the specific type of the reset elastic member 90 is not limited in the embodiment of the present application.

[0062] In addition, in the embodiment of the present application, when the seat is switched from a folded state to an open state, the connection position of the connector 40 and the seat belt buckle 30 can be set according to the force requirements so that the connector 40 can also drive the mounting plate 32 to rotate counterclockwise relative to the bracket 10.

[0063] Optionally, in the embodiment of the present application, Figure 3 and Fig. 9 as well as Fig.10 As shown, the bracket 10 includes a first base frame 11 and a second base frame 12 connected to each other, the rotating link 20 is rotatably connected to the first base frame 11, and the safety belt buckle 30 is rotatably connected to the second base frame 12; the first base frame 11 and the second base frame 12 are enclosed to form a receiving groove 13, and the connecting member 40 is at least partially received in the receiving groove 13. In this way, the connection between the bracket 10 and the rotating link 20 is realized through the first base frame 11, and the connection between the bracket 10 and the safety belt buckle 30 is realized through the second base frame 12, and the receiving groove 13 enclosed by the first base frame 11 and the second base frame 12 provides a receiving space for the connecting member 40, thereby improving the space utilization rate, preventing the connecting member 40 from being exposed, and preventing the connecting member 40 from being easily damaged by friction during the assembly process.

[0064] For example, in an embodiment of the present application, the seat cushion assembly may further include a fixing frame, the bracket 10 may be connected to the fixing frame, the first base frame 11 and the second base frame 12 are both fixedly connected to the fixing frame, and the fixing frame may be used to connect to the vehicle body, so that the seat cushion assembly has a more stable connection with the vehicle body.

[0065] In summary, the seat cushion assembly described in the embodiment of the present application can at least include the following advantages:

[0066] In the embodiment of the present application, the seat cushion assembly includes: a bracket, a rotating link, a safety belt buckle and a connecting member; the rotating link and the safety belt buckle are respectively arranged on the bracket, and the rotating link and the safety belt buckle are respectively connected to the bracket, one end of the connecting member is connected to the rotating link, and the other end of the connecting member is connected to the safety belt buckle; the rotating link rotates relative to the bracket to drive the connecting member to move, and the connecting member drives the safety belt buckle to rotate relative to the bracket. In this way, when the seat is flipped and adjusted, the rotating link rotates, and since one end of the connecting member is connected to the rotating link, the other end of the connecting member is connected to the safety belt buckle, that is, the connecting member is connected between the rotating link and the safety belt buckle. Therefore, the rotation of the rotating link drives one end of the connecting member to move, and the other end of the connecting member drives the safety belt buckle to rotate, so that the rotation of the rotating link drives the safety belt buckle to rotate at the same or similar angle through the connecting member, and realizes the synchronous linkage between the rotating link and the safety belt buckle. In this way, since the seat is flipped, the seat belt buckle rotates synchronously, the backrest is prevented from abutting against the seat belt buckle when folded, the wear on the outer surfaces of the seat belt buckle and the backrest is reduced, the service life of the seat belt buckle is increased, and the backrest has a better appearance.
