Description

Technical Field

[0001] The utility model relates to the technical field of automobile interior decoration structure, in particular to a double-door handrail, a box body and an automobile. Background Art

[0002] At present, there are two common styles of armrests in the auxiliary instrument and glove box of automobile interior parts, namely, the rear-flip armrest and the double-door armrest. The double-door armrest is a double-door form in which the left door and the right door are flipped separately. The opening time of this double-door armrest is the time required for the driving force to overcome the resistance and produce displacement to reach the specified stroke. The existing functional styles of this armrest on the market generally use the pre-stress angle and elastic coefficient of the torsion spring as the driving force to overcome the gravity of the armrest cover, the rotational resistance of the damping, and the axial and radial friction of the shaft hole matching, so that the left and right doors of the armrest can be flipped to reach the set stroke.

[0003] Usually, due to the differences in torsion spring manufacturing accuracy, injection molded parts dimensional accuracy (affecting friction), damping torque, etc., the left torsion spring driving force is ≠ the right torsion spring driving force, and the left opening resistance is ≠ the right opening resistance. In this way, it is difficult to ensure that the opening time of the left and right doors is completely consistent, which will cause the problem of asynchronous opening of the left and right doors. Or in the early stage of production, a large number of manual adjustments are used to make the opening time of the left and right doors consistent, but after long-term use by users, the mechanical properties and friction of springs, dimensional matching, dampers, etc. will decay accordingly, and there will still be differences between the left and right. This causes a decline in user experience and a lack of high-end and refined feeling. Utility Model Content
