Specifically, a gear 250 is coaxially arranged on the output shaft 221 of the inner motor 220, the gear 250 is arranged in the groove 233 and meshes with the arc-shaped teeth 234, so that the inner motor 220 drives the gear 250 to rotate in the groove 233 , and then through the meshing of the gear 250 and the arc-shaped tooth 234, the inner cantilever 232 is driven and thus the entire inner armrest 230 is driven to rotate around the rotating shaft 240 or around the axis B, thereby realizing that the inner armrest 230 is relative to the inner bracket 210 and thus relative to the seat. Rotation of pad 300 .

Slot 233 has at least one end 233b, and this end 233b is in order to define the second position of inner armrest (that is, the position of inner armrest 230 in Fig. When the end 233b of the groove 233 is reached, the further rotation of the inner cantilever 232 in this direction is limited, that is, the inner armrest 230 is limited to continue to rotate in the corresponding direction, so the end 233b of the groove 233 defines the limit to which the inner armrest 230 faces downward. The angle of rotation, that is, the inner armrest 230 is limited to the second position of the inner armrest by the end 233b.

Referring to Fig. 5, a stop portion 2121a is also provided on the rear support plate 2121, and a corresponding stop portion 232a is provided on the inner cantilever 232, the stop portion 2121a cooperates with the corresponding stop portion 232a to define the inner armrest The first position (that is, the position where the inner armrest 230 is located in FIG. When in contact with the corresponding stop portion 232a provided on the inner cantilever 232, the further rotation of the inner armrest 230 in this direction is restricted. Therefore, the stop portion 2121a and the corresponding stop portion 232a limit the upward limit of the inner armrest 230. The rotation angle defines the first position of the inner armrest 230 (the position of the inner armrest 230 in FIG. 8 a ).

In some embodiments, the stop portion 2121a and the corresponding stop portion 232a may include any one of protrusions, steps, and flanges. As shown in FIG. 5 , the corresponding stop portion 232 a may be the other end of the slot 233 opposite to the end 233 b.

The rear support plate 2122 is provided with a shaft hole 214 for accommodating the output shaft 221 of the inner motor 220 (of course, when the inner electrode 220 is installed on the rear support plate 2122, the rear support plate 2121 may also be provided with a shaft hole 214 for the shaft hole of the output shaft 221 of the inner motor 220), a shaft sleeve (similar to the shaft sleeve in the embodiment shown in Fig. 2 ) is arranged in the shaft hole 214, and the output shaft 221 of the inner motor 220 passes through the shaft sleeve . A torsion spring 270 is wound on the sleeve. The first end of the torsion spring 270 is connected with the rear support plate 2122 (of course, when the shaft hole for accommodating the output shaft 221 of the inner motor 220 is arranged on the rear support plate 2121, the first end of the torsion spring can also be connected with the rear support plate 2121. rear support plate 2121), the second end of the torsion spring 270 is connected with the inner cantilever 232, so that the arc-shaped teeth 234 of the inner cantilever 232 can always keep meshing with the gear 250.

In some embodiments, in order to better ensure the synchronization between the inner armrest 230 and the outer armrest 130 during rotation, the rotation axis 240 or axis B of the inner armrest 230 and the rotation axis 140 or axis A of the outer armrest 130 can be coaxial ground setting.

In some embodiments, the inner armrest 230 may be integrated with functional parts that require a use angle, such as a cup holder or a display screen.

Referring to Fig. 7a to Fig. 7c, the outer armrest 130 shown in Fig. 1 and Fig. 2 can be moved between the first position shown in Fig. 7a and the second position shown in Fig. 7c under the drive of the outer motor 120 Turn over, and make the outer armrest 130 stay in any position between the first position and the second position. For example, FIG. 7 b shows the horizontal position of the outer armrest 130 in its horizontal state, wherein the outer armrest 130 , in particular the outer support panel 131 , is in the horizontal state. Here, the first position of the outer armrest 130 may be a position where the outer armrest 130 points upward, and the first position may be defined as a welcoming position or/and a seeing-off position of the outer armrest. In the first position of the outside armrest shown in Figure 7a, the outside armrest 130 may be oriented vertically at an angle of 90° relative to the horizontal position of the outside armrest shown in Figure 7b (of course, the armrest angle in the first position It is not limited to 90°, preferably, the angle of the armrest can be 90°-120°), and when the outer armrest is in the first position, it is convenient for the occupant to sit on the seat or leave the seat. The second position of the outer armrest may be that the outer armrest 130 is inclined forward and downward (as shown in FIG. 7c ) and at an angle of 15° (more precisely -15°) relative to the horizontal position of the outer armrest shown in FIG. 7b , which is mainly to facilitate the occupant's arms to be supported obliquely downward on the outer armrest.

Referring to Figures 8a to 8c, the inner armrest 230 shown in Figures 3 and 4 can be turned over between the first position shown in Figure 8a and the second position shown in Figure 8c under the drive of the inner motor, and The inner armrest 230 may be left in any position between the first position of the inner armrest and the second position of the inner armrest. For example, Fig. 8b shows the horizontal position of the inner armrest 230 in its horizontal state, wherein the inner armrest 230, in particular the first part 2311 of the inner support panel 231, is in the horizontal state. In the first position of the inner armrest 230, the inner armrest 230 is inclined forward and upward (as shown in Fig. 8a), and the angle relative to the horizontal position shown in Fig. 8b is 5°.
