Sliding rotating shaft mechanism and armrest box armrest

Abstract

The invention relates to a sliding rotating shaft mechanism and an armrest box armrest. The sliding rotating shaft mechanism comprises a sliding rotating cantilever, a sliding rotating rail support, a straight tooth one-way ratchet wheel, a left spiral spring, a check spring piece, a right spiral spring, a straight tooth coil spring protective cover, a coil spring and a two-way ratchet wheel protective cover, wherein one end of the sliding rotating cantilever is integrated onto an armrest cover plate part, the sliding rotating cantilever comprises a left arm and a right arm, the left arm and the right arm are arranged in a left-and-right spaced mode, the sliding rotating rail support comprises a left sliding rotating rail and a right sliding rotating rail, and the left sliding rotating rail and the right sliding rotating rail are arranged in a left-and-right spaced mode. Linear rails and rotary rails are adopted, the armrest slides linearly and then move rotatably through matching of the ratchet wheel, gears, toothed rails, springs and the like, and therefore limits of the mechanism on armrest modeling and spatial arrangement are reduced; the armrest achieves the functions of damping and stagnation close to any position, and can achieve the function of automatic returning of the mechanism.

Description

technical field [0001] The invention relates to a turning device for an armrest of an auxiliary instrument panel of an automobile, in particular to a sliding and rotating shaft mechanism and an armrest of an armrest box. Background technique [0002] According to the requirements of different configurations, the sub-dashboard of the car will be equipped with armrest assembly parts to provide a comfortable elbow position for the driver or passenger. At the same time, most armrest assemblies have the function of flipping and opening. To design a storage space, the armrest is equivalent to a storage box cover. However, under normal circumstances, as far as the armrest function is concerned, most armrests can only provide the support function of the occupant's elbow when they are closed, and they cannot support the force after they are opened. Therefore, such an armrest assembly has a single position and cannot Meet the body size or needs of as many occupants as possible. [0...

Problems solved by technology

[0004] However, because the rotation of the above-mentioned existing handrails is realized only by one fixed rotation axis, that is, the trajectories of the handrails are all circular trajectories, and the single rotation axis is relatively limited by the space, and the part structure can only be arranged in a small range , therefore, there will be specific restrictions on the shape of the surrounding parts or the space required by the mechanism
