[0026] The utility model will be further described below in combination with the embodiments and the drawings.

[0027] As shown in Figure 1 and Figure 4 , a seat armrest mounting structure comprises a seat body and a driving mechanism, the seat body has a seat support assembly A and armrest supports 4 arranged on both sides of the seat support assembly A in the width direction. The armrest supports 4 and the seat support assembly A are provided with a first connecting rod 2 and a transmission arm 3, wherein the two ends of the first connecting rod 2 are respectively rotatably connected to the armrest supports 4 and the rear part of the seat support assembly A, the two ends of the transmission arm 3 are respectively rotatably connected to the armrest supports 4 and the front part of the seat support assembly A, the armrest supports 4, the first connecting rod 2, the seat support assembly A and the transmission arm 3 constitute a four-connecting-rod mechanism. The driving mechanism can drive the four-connecting-rod mechanism to move.

[0028] Based on the above structural design, since the armrest supports 4, the first connecting rod 2, the seat support assembly A and the transmission arm 3 constitute a four-connecting-rod mechanism, therefore, by Figure 5It can be seen that when the seat body posture changes, the four-bar linkage mechanism can be driven to move by the driving mechanism to adjust the support angle of the armrest support 4, so that the user's elbow can be comfortably supported in different sitting postures, and the touch screen or button on the armrest can also be easily controlled in the lying posture. The different postures described in this paragraph mainly refer to the reclining state of the backrest alone. Of course, it can also refer to the zero-gravity state in which the backrest and the cushion are both inclined. The following will be further described taking the armrest applied to a zero-gravity seat as an example.

[0029] As shown in Figure 1 and 4 , the seat is a zero-gravity seat, and the seat support assembly A includes a base A2 for mounting to the floor of the vehicle and a seat frame A1 located above the base A2. The rear end of the seat frame A1 is rotatably connected to the base A2, and the rear end of the seat frame A1 is rotatably connected to the backrest 9. In combination with Figure 2 , an upper linkage piece 51 and a lower linkage piece 52 are provided between the front end of the seat frame A1 and the base A2. One end of the upper linkage piece 51 is rotatably connected to the seat frame A1, and the other end is hingedly connected to the lower linkage piece 52. The end of the lower linkage piece 52 away from the upper linkage piece 51 is rotatably connected to the base A2. The end of the transmission arm 3 away from the armrest support 4 is fixedly connected to the lower linkage piece 52, and the driving mechanism can drive the lower linkage piece 52 to rotate relative to the base A2.

[0030] Based on this, referring to Figure 4 and 5 , the armrest support 4, the transmission arm 3, and the lower linkage piece 52 form a four-bar linkage mechanism, and the base A2 and the first linkage 2. During the process of converting the seat from a sitting posture to a zero-gravity state, the driving mechanism drives the lower linkage piece 52 to rotate upward, and the forward end of the lower linkage piece 52 moves upward to drive the rear end of the upper linkage piece 51 to lift upward, thereby realizing the upward rotation of the front part of the seat frame A1. Therefore, by fixing the transmission arm 3 and the lower linkage piece 52 or designing them as a whole, without adding an additional driving source, the lower linkage piece 52 can be rotated upward, and the armrest support 4 can be moved backward and upward relative to the base A2.

[0031] As shown in Figure 1 and 2 , in this embodiment, the lower linkage piece 52 is rotatably installed on both sides of the seat frame A1 in the width direction through the angle adjuster c. The driving mechanism includes a motor 61 and a synchronous rod 62 driven to rotate by the motor 61, and the two ends of the synchronous rod 62 are in transmission connection with the angle adjuster c. The motor 61 drives the synchronous rod 62 to rotate, which can drive the lower linkage pieces 52 on both sides to rotate relative to the base A2.

[0032] Please refer to Figure 2The lower end of the transmission arm 3 is fixed to the outer side of the lower linkage piece 52 through the transition support 8, so that the handrail support 4 can be installed outwardly and translationally, the distance between the two groups of handrail supports 4 is increased, and the seat space is ensured.

[0033] As shown in Figure 4 , the front lower side of the handrail support 4 is provided with a cantilever 41 extending to the base A2, and the end of the transmission arm 3 away from the base A2 is hinged to the end of the cantilever 41.

[0034] Further referring to Figure 4 , the seat support assembly A is provided with the transition frame 1 extending upwardly at the position corresponding to the handrail support 4, in the embodiment, the transition frame 1 is fixed to the base A2, and the upper end of the transition frame 1 is located on the inner side of the corresponding handrail support 4. Figure 3 As shown in , the handrail support 4 is provided with the arc-shaped slot 4a, and the transition frame 1 is provided with the guide pillar a slidingly supported in the arc-shaped slot 4a. In the embodiment, the arc-shaped slot 4a is inclined. Through the transition frame 1, the guide pillar a and the arc-shaped slot 4a, the rotation angle and the moving range of the handrail support 4 can be limited when the lower linkage piece 52 rotates, and the shaking amount of the handrail support 4 in the Y direction can also be limited, that is, the left and right shaking of the handrail support 4 is limited, and the stability of the seat handrail is improved.

[0035] Figure 4 Further, as shown in , the transition frame 1 is provided with the adapter plate 1b at the lower part, and the end of the first connecting rod 2 away from the handrail support 4 is hinged to the rear end of the adapter plate 1b.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present application, and those skilled in the art can make various similar modifications under the inspiration of the present application without departing from the purpose and claims of the present application, and such modifications fall within the protection scope of the present application.
