Damping-variable balance supporting rod for automobile tail door
The invention discloses a variable damping balance supporting rod for an automobile tail door, which comprises a spiral spring and a damping mechanism, the damping mechanism is a variable damping mechanism, the variable damping mechanism comprises a guide rod, an outer sleeve, an inner sleeve and a pair of pressing blocks which are movably arranged relatively, the inner sleeve is positioned in the outer sleeve and is connected with one end of the guide rod, and the other end of the guide rod is connected with the outer sleeve. The pair of pressing blocks can be movably arranged in the inner sleeve in the radial direction, and a compressed elastic element and an electromagnetic induction coil used for generating magnetic force to attract the pressing blocks are arranged between the pair of pressing blocks. Damping is arranged in the balance supporting rod under the power-off working condition, friction damping is also arranged in the electric supporting rod, and the two kinds of damping jointly support the tail door to enable the tail door to hover. Under the power-on working condition, the internal damping of the balance supporting rod is greatly reduced, the electric supporting rod only overcomes the friction damping of the electric supporting rod when working, and the resistance overcome by the electric supporting rod is reduced, that is, the motor power required during working is reduced.
本发明公开了一种汽车尾门用可变阻尼的平衡撑杆，包括螺旋弹簧和阻尼机构，所述阻尼机构为可变阻尼机构，所述可变阻尼机构包括导向杆、外套筒、内套筒以及相对活动设置一对压块，所述内套筒位于外套筒内与导向杆一端相连，一对压块可径向活动的设在内套筒中，所述一对压块之间设有压缩的弹性元件和用于产生磁力吸引压块的电磁感应线圈。在未通电工况下平衡撑杆内部有阻尼，电动撑杆内部也有摩擦阻尼，两种阻尼共同支撑尾门使之悬停；在通电工况下，平衡撑杆内部阻尼大幅减少，电动撑杆工作时仅克服自身的摩擦阻尼即可，电动撑杆克服的阻力减小，即工作时所需的电机功率减小。
