Buffer hinge
The invention provides a buffer hinge comprising a fixed base, a cam shaft which is fixedly arranged on the fixed base and comprises a cam part, a movable base which is pivoted on the cam shaft and adamping unit. The cam part is provided with an outer contour surface, the cam shaft is provided with a central point, and a curvature radius can be defined between the outer contour surface and the central point. The damping unit comprises a damping driven piece which is movably arranged on the movable base and abuts against the outer contour surface. When the movable base rotates from the first door opening position to the door closing position, the curvature radius of the contact position of the damping driven piece and the outer contour surface is continuously increased, and the resistancebetween the damping driven piece and the outer contour surface is continuously increased. When the movable base rotates from the first door opening position to the second door opening position, the curvature radius of the contact position of the damping driven piece and the outer contour surface is kept unchanged, and the resistance between the damping driven piece and the outer contour surface iskept unchanged.
一种缓冲铰链，包含固定座、固定地设置于所述固定座并包括凸轮部的凸轮轴、枢设于所述凸轮轴的活动座，及阻尼单元。所述凸轮部具有外轮廓面，所述凸轮轴具有中心点，所述外轮廓面与所述中心点之间能定义出曲率半径。所述阻尼单元包括能移动地设置于所述活动座并与所述外轮廓面抵接的阻尼从动件。当所述活动座从第一开门位置朝关门位置转动时，所述阻尼从动件与所述外轮廓面的接触之处的所述曲率半径持续变大，所述阻尼从动件与所述外轮廓面之间的阻力持续增加。当所述活动座从所述第一开门位置朝第二开门位置转动时，所述阻尼从动件与所述外轮廓面的接触之处的所述曲率半径保持不变，所述阻尼从动件与所述外轮廓面之间的阻力保持不变。
