Description

Technical Field

[0001] The utility model relates to the technical field of vehicle seats, in particular to a rear seat which is convenient to sink after being flipped. Background Art

[0002] Chinese Patent No. CN 117922400 A discloses a rear seat structure which is convenient to sink after being quickly flipped, including a headrest, a backrest and a seat cushion. Rotating shafts are fixedly arranged at both ends of the seat cushion. When the headrest moves down to the lowest position, the headrest can fit with the backrest. When the backrest is flipped forward until it abuts against the seat cushion, the headrest can be received between the backrest and the seat cushion. The seat cushion includes a seat cushion skeleton, which includes an outer frame, transverse branch pipes and longitudinal branch pipes. The floor lock is rotatably installed on the transverse branch pipes. Each floor lock is equipped with a cable mechanism and a compensation spring. One end of the cable in the cable mechanism is connected to the floor lock, and the other end is connected to the compensation spring. The compensation spring is arranged on the rotating shaft. The driving mechanism can drive the rotating shaft to flip backward, so as to drive the compensation spring, the backrest and the seat cushion to flip backward together. When the compensation spring flips, it can drive the cable to move, and further pull the floor lock to flip backward to the received state. Although this structure can reduce the overall external dimension of the whole chair after receiving and improve the overall receiving effect of the rear seat, this structure is provided with an external locking mechanism for locking after the seat returns to the designed position, which has the disadvantages of single function, complex flipping and linkage structure, and requires a large number of components, which is not conducive to popularization and use. Summary of the Utility Model

[0003] Aiming at the problems existing in the above-mentioned prior art, the utility model aims to provide a rear seat which is convenient to sink after being flipped, which can cancel the external locking mechanism at the front end of the seat, simplify the product structure and reduce the number of parts.

[0004] To achieve the above object, the utility model provides a rear seat which is convenient to sink after being flipped, including a seat cushion skeleton and a backrest skeleton which can be flipped flat around the seat cushion skeleton. The lower end of the backrest skeleton is hinged to the rear end of the seat cushion skeleton. A receiving groove is arranged on the vehicle body floor at the rear side of the seat cushion skeleton. The front end of the seat cushion skeleton is movably supported on the vehicle body floor. The rear seat further includes two first angle adjusters and two base brackets arranged at the rear end of the seat cushion skeleton. The two first angle adjusters and the two base brackets are arranged relatively left and right. The first angle adjuster is installed between the seat cushion skeleton and the corresponding base bracket. The lower ends of the two base brackets are fixed on the vehicle body floor. A first synchronous rod is connected between the two first angle adjusters. A first flipping motor is installed on the first synchronous rod. The first flipping motor is fixed on the seat cushion skeleton. The first flipping motor can drive the first synchronous rod to rotate, so as to drive the seat cushion skeleton and the backrest skeleton flipped flat on the seat cushion skeleton to rotate backward together and sink into the receiving groove.

[0005] In the above solution: the front end of the seat cushion frame is movably supported on the vehicle body floor by two support frames. The two support frames are arranged at intervals at the bottom of the front end of the seat cushion frame. A rubber pad is fixedly provided at the bottom of the support frame, and a support point is provided on the vehicle body floor at the position corresponding to the rubber pad. This structure uses a support frame to replace the original folding and locking mechanism, greatly simplifying the part structure and quantity.

[0006] In the above solution: the lower end of the backrest frame is hinged to the rear end of the seat cushion frame by two second angle adjusters arranged oppositely left and right. A second synchronizing rod is provided between the two second angle adjusters. A second flipping motor is installed on the second synchronizing rod. The second flipping motor is fixed to the backrest frame by a sheet metal bracket. The second flipping motor can drive the second synchronizing rod to rotate, thereby driving the backrest frame to flatten around the seat cushion frame. The flipping structure is simple and convenient for assembly.

[0007] In the above solution: the seat cushion frame includes a seat frame. Angle adjuster mounting brackets are welded to the rear sides of both ends of the seat frame. The moving ends of the two first angle adjusters are welded to the two angle adjuster mounting brackets one by one. That is, the angle adjuster mounting brackets are provided to facilitate the installation of the first angle adjusters on the seat frame. Also, since it is difficult to integrally process the seat frame and the angle adjuster mounting brackets, they are processed and installed separately.

[0008] In the above solution: the seat cushion frame further includes two connecting plates. The two angle adjuster mounting brackets are respectively fixed to the lower ends of the two connecting plates. The lower end of the backrest frame is hinged to the upper ends of the two connecting plates by two second angle adjusters one by one, thereby realizing the hinge connection with the seat cushion frame. The connecting plates play a role in connecting the backrest frame and the seat cushion frame up and down. It is difficult to integrally process the connecting plates and the angle adjuster mounting brackets, so they are processed and installed separately. The lower ends of the connecting plates can be specifically fixed to the angle adjuster mounting brackets by two screws.

[0009] In the above solution: a square tube is arranged between the two angle adjuster mounting brackets. The first flipping motor is fixed to the square tube by a sheet metal bracket. The square tube is beneficial to improving the overall stability of the seat cushion frame and can also provide a fixed installation point for the first flipping motor.

[0010] The beneficial effects of the present utility model are:

[0011] 1. The first flipping motor drives the first synchronizing rod to rotate, thereby driving the seat cushion frame and the backrest frame laid flat on the seat cushion frame to rotate backward together until they rotate into the receiving groove, achieving the flatness of the surface of the seat cushion frame with the vehicle body floor, saving space, effectively improving the overall storage effect of the rear seats, and during the entire backward rotation process, there is only one rotating shaft, with a simple overall structure, convenient processing, and easy to promote and use; 2. The front end of the seat cushion frame is directly movably supported on the vehicle body floor, canceling the external locking mechanism at the front end of the seat, and the flipping and locking of the seat cushion frame are completed by the first angle adjuster, simplifying the product structure and reducing the number of parts.
