Detailed Description

As shown in fig. 1 to 4, the utility model relates to a damping type handrail structure of automobile rear seat belt, which comprises a handrail 1, a limiting plate 3 and a handrail mounting bracket 2. In fig. 1, the position a is the designed state of the armrest, and the position B is the state of the armrest 1 after being turned downward.

The two sides of the armrest 1 are respectively connected with the middle of the backrests (not shown in the figure) of the two seats through armrest mounting brackets 2. The limiting plate 3 is connected to the inner side of one handrail mounting bracket 2 and is simultaneously connected with the rotating shaft 8 and the limiting shaft 7 of the handrail 1. The limiting plate 3 is formed by integral injection molding, and the limiting plate 3 is made of PP material in the embodiment. The stopper plate 3 is provided with a rotation shaft mounting hole 14 and a handrail rotation damping groove 4 provided on the side of the rotation shaft mounting hole 14. One side of the rotating shaft mounting hole 14 is connected with a rotating shaft sleeve 15, and the rotating shaft sleeve 15 is an integral component which is integrally injection-molded with the limiting plate 3. The handrail rotation damping slot 4 comprises an upper limiting slot 13 positioned on the upper side, a lower limiting slot 9 positioned on the lower side and an arc-shaped excess damping slot 11 connected between the upper limiting slot 13 and the lower limiting slot 9, wherein the upper limiting slot 13 and the lower limiting slot 9 are respectively circular. A damping bump I12 is arranged at the joint of the upper limiting groove 13 and the excessive damping groove 11 in a protruding mode, and the arrangement of the damping bump I12 enables the groove width of the joint of the upper limiting groove 13 and the excessive damping groove 11 to be narrow. A damping salient point II 10 is convexly arranged at the joint of the lower limiting groove 9 and the excessive damping groove 11, and the arrangement of the damping salient point II 10 enables the groove width at the joint of the lower limiting groove 9 and the excessive damping groove 11 to be narrowed. The end of the stopper shaft 7 of the armrest 1 is positioned in the rotation shaft mounting hole 14 and the rotation shaft bushing 15, and the rotation shaft 8 is positioned in the armrest rotation damping groove 4. The both sides of the rotatory damping slot 4 of handrail of limiting plate 3 are outstanding respectively and are equipped with buckle 5 that can mutually support with handrail installing support 2, are equipped with the positioning hole 6 of mutually supporting with buckle 5 on the handrail installing support 2, and the position of limiting plate 3 and handrail installing support 2 can effectively be fixed a position in buckle 5 and the 6 cooperation of positioning hole.

In this embodiment, the armrest 1 includes an armrest frame and an armrest foam, and the armrest 1 is an integrated armrest in which the armrest frame and the armrest foam are integrally formed by foaming. The handrail framework comprises a handrail framework pipe 16, a handrail transverse steel wire 17, a rotating shaft 8 and a limiting shaft 7, wherein the handrail framework pipe 16 is formed by bending a metal pipe, the handrail transverse steel wire 17 is connected to the inner side of the handrail framework pipe 16, and the rotating shaft 8 and the limiting shaft 7 are connected to one end of the handrail framework pipe 16 in parallel.
