As shown in FIG. 1 and FIG. 2 , an embodiment of the present invention provides a seat hinge assembly, which includes a bracket 1, a connecting rod 2 and a connecting shaft 3. The bracket 1 is used to be installed on the seat guide rail 50, and the connecting rod 2 One end of the connecting rod 2 is rotatably connected to the connecting shaft 3, and the other end of the connecting rod 2 is used to be hinged to the seat frame 60. The bracket 1 is provided with a chute 11. The chute 11 extends along the preset trajectory of the connecting shaft 3, and the connecting shaft 3 is inserted into the chute 11 and is used to slide along the chute 11. The preset trajectory of the connecting shaft 3 is the movement trajectory of the connecting shaft 3 when the seat is adjusted up and down.

Specifically, a seat hinge assembly is usually provided on the left and right sides of the front end of the seat frame 60, and a seat rail 50 and a seat guide groove assembly 40 are provided on the left and right sides below the seat frame 60. The seat The guide rail 50 slides forward and backward on the seat guide channel assembly 40, and the seat guide rail 50 and the seat guide channel assembly 40 are arranged corresponding to the seat hinge assembly. In addition, driving mechanisms 70 are respectively provided on the left and right sides of the front end of the seat frame 60. and the driven rod 90, and the driving mechanism 70 and the driven rod 90 are respectively connected to the left and right ends of the seat rotating shaft 80. Among them, the bracket 1 of the seat hinge assembly is usually fixed on the corresponding seat rail 50 by, for example, welding or clamping, and one end of the connecting shaft 3 is rotationally connected to one end of the connecting rod 2, and the other end of the connecting rod 2 is usually The pin is hinged to one side of the seat frame 60, and the other end of the connecting shaft 3 passes through the chute 11 and is connected to the driving mechanism 70 or the driven rod 90. For example, as shown in Figure 2, for the left side of the seat frame 60 For the seat hinge assembly on the side, the connecting shaft 3 is connected to the driving mechanism 70. The driving mechanism 70 is used to drive the seat rotating shaft 80 to rotate and drive the connecting shaft 3 to slide in the chute 11. The connecting shaft 3 drives the connecting rod 2 While rotating around its hinge with the seat frame 60, it also moves up and down, thereby driving the seat up and down. For the seat hinge assembly located on the right side of the seat frame 60, its connecting shaft 3 is connected to the seat frame 60 through the driven rod 90. The seat rotating shaft 80 is connected, and the driving mechanism 70 drives the seat rotating shaft 80 to rotate and also drives the connecting shaft 3 to slide along the chute 11 , so that the connecting shaft 3 on the right side can also move along the preset trajectory under the action of the driving mechanism 70 , to realize the lifting and lowering of the seat.

More specifically, the bracket 1 may have a fan-shaped structure as shown in FIG. 3 , a trapezoidal structure as shown in FIG. 4 , or a special-shaped structure as shown in FIG. 6 , which is not specifically limited here. The shape of the chute 11 matches the movement trajectory of the connecting shaft 3 when it moves under the action of the driving mechanism 70 or the driven rod 90 , that is, the chute 11 extends along the preset trajectory of the connecting shaft 3 , and normally, The connecting shaft 3 rotates around the seat rotation axis 80 under the action of the driving mechanism 70 or the driven rod 90, that is, the movement trajectory/preset trajectory of the connecting shaft 3 is arc-shaped, so the chute 11 is usually arc-shaped. Moreover, when the connecting shaft 3 slides along the chute 11 in the chute 11, the connecting shaft 3 always fits the groove wall of the chute 11, that is, the connecting shaft 3 is always in contact with the groove wall of the chute 11. It should be noted that , it can be that the two radial surfaces of the connecting shaft 3 are in contact with the two groove walls arranged opposite to the chute 11, as shown in Figure 1.
