Large armrest of rear-row seat

Abstract

The invention discloses a large armrest of a rear seat. The large armrest comprises a support and a large armrest framework, a fixed shaft component is fixedly assembled on the support, and the fixed shaft component is provided with a folding limiting part and a use supporting part; a movable support is fixedly connected to the side wall of one end of the large armrest framework, the movable support is assembled on the fixed shaft component in a rotatable mode, a positioning shaft is arranged on the movable support, and the rotating stroke of the movable support is limited between the folding limiting part and the using supporting part through the positioning shaft; the main locking block is rotationally installed on the movable support, a first elastic element is arranged between the main locking block and the movable support, and when the positioning shaft moves to the inner side position of the folding limiting part, the first elastic element enables the main locking block to apply thrust to the folding limiting part so as to force the positioning shaft to be tightly attached to the folding limiting part; an inhaul cable is connected between the unlocking assembly and the main locking block and used for pulling the main locking block to leave the folding limiting part. The large armrest has the beneficial effect that it can be guaranteed that no shaking gap exists in the locking position of the large handrail.

Description

technical field [0001] The invention relates to a car armrest, in particular to a large armrest of a rear seat. Background technique [0002] In some models, the middle part of the rear seat is equipped with an armrest, that is: a large armrest. In addition to the hand support function, the large armrests of the rear seats are also integrated with cup holders, control panels and other components on some high-end models. Therefore, the assembly accuracy of the large rear armrests should have more stringent requirements. [0003] However, in the prior art, the locking of the large armrest in the folded state is achieved by means of a limit pin. In order to ensure that the limit pin can be locked into the corresponding hole, there should be a clearance fit between the limit pin and the hole. , and due to the influence of manufacturing precision and assembly precision, there will be a certain amount of sway in the limit pin. Although the sway gap is small, when it is refracted ...

[0003] However, in the prior art, the locking of the large armrest in the folded state is achieved by means of a limit pin. In order to ensure that the limit pin can be locked into the corresponding hole, there should be a clearance fit between the limit pin and the hole. , and due to the influence of manufacturing precision and assembly precision, there will be a certain amount of sway in the limit pin. Although the sway gap is small, when it is refracted to the far end of the large armrest, the amount of sway will be significantly amplified, which seriously reduces the The installation quality of the armrest, which in turn affects the ride experience of the rear passengers
