Specifically, in this embodiment, the sliding rail 21 is a U-shaped rail, two ends of the sliding rail 21 are bent inwards, the second sliding groove 35 is a U-shaped groove corresponding to the sliding rail 21, and a bending portion matching with the bending of the sliding rail 21 is formed on the second sliding groove 35, so as to achieve the linear movement of the second sliding groove 35 on the sliding rail 21, and it should be noted that the second sliding groove 35 and the sliding rail 21 have smooth surfaces to reduce the friction force between the second sliding groove 35 and the sliding rail 21.

Further, as shown in fig. 2, two sliding seats 20 are provided, the two sliding seats 20 are arranged at intervals along the direction perpendicular to the first direction x, and the moving seat 31 is slidingly connected with the two sliding seats 20 at the same time. It will be appreciated that the two sliding seats 20 are provided to allow smooth linear movement of the movable seat 31 in the fore-and-aft direction, and to ensure that the movable seat 31 does not tilt or rock during movement. In addition, the cooperation of the two sliding seats 20 can balance the weight and load of the moving seat 31, so that the moving seat 31 is more stable and safer.

In an embodiment, a mounting seat 311 is disposed at the bottom of the moving seat 31, the mounting seat 311 is located between the two sliding seats 20, and the driving member 10 is fixed on the mounting seat 311. That is, the driving member 10 is disposed between the two sliding seats 20, thereby fully utilizing the space between the two sliding seats 20; and, after the driving piece 10 is directly installed on the installation seat 311, the power source and the seat 30 can form an integral structure, and an additional accommodating space is not required to be arranged on the vehicle body, so that the integral installation of the automobile rear seat 100 is more convenient, and the space utilization rate is improved.

Specifically, the mounting seat 311 is formed with a mounting groove (not shown) of the driving member 10, which extends in a direction perpendicular to the sliding direction of the moving seat 31. In this way, the driving member 10 is installed in the installation groove, and the output shaft 11 is disposed along the extending direction of the installation groove and connected to the screw 50.

In one embodiment, the end of the pivotal connection between the backrest 32 and the movable seat 31 may be a pivotal or hinged connection. Here, the backrest 32 is connected to the movable seat 31 in a hinged manner.

Further, a fixing seat 36 is provided on a side surface of the backrest 32, and the stop lever 34 is provided on the fixing seat 36. Thereby realizing the installation of the limit rod 34 on the side surface of the backrest 32 through the switching of the fixed seat 36.

As shown in fig. 3, the backrest 32 forms an angle a with a direction perpendicular to the first direction x. The angle a will vary with the movement of the movable seat 31 in the first direction x, and the rotation of the screw 50 will drive the threaded sleeve 33 to move on the screw 50, thereby realizing the movement of the movable seat 31. Here, when the screw 50 is rotated, the stroke of the preset thread bush 33 on the screw 50 is d (unit: mm), and at this time, the following relationship is satisfied between d and a: a=28+0.1×d, where the range of d satisfies: 0. and d is more than or equal to 100. For example, when d=0 mm, the angle a=28°, that is, in the initial state, the backrest 32 forms an angle of 28 ° with the direction perpendicular to the first direction x. When d=100 mm, a=28+0.1×100, i.e. a=38°, this gives an adjustment range of the angle a between 28 ° and 38 °.
