摘要： A latch housing for a carriage latch in a disc drive comprising a cantilever beam and a buckling beam. The cantilever beam and the buckling beam are so oriented in relation to each other and the path of the carriage that contact between a latching feature on the moving carriage and the carriage latch occurs with the beams at an original position and causes the cantilever beam to deflect in a cantilever mode and the buckling beam to deflect in a buckling mode until the kinetic energy of the moving carriage is converted to internal stresses in the material of the beams. Reactive motion of the beams due to these internal stresses is limited to a return to the original position by leashing action of the buckling beam. In a preferred embodiment, the latch housing is realized as a one-piece molded component, and the material of the component as well as the dimensions and shapes of the cantilever beam and buckling beam are all selected to limit the motion caused by contact between the moving latch feature and the latch to a single excursion from the original position to a maximum deflected position and back to the original position.
摘要翻译：一种用于在盘驱动器中的滑架闩锁的闩锁壳体，其包括悬臂梁和屈曲梁。悬臂梁和弯曲梁相对于彼此定向，并且在移动的托架上的闩锁特征与托架闩锁之间接触的托架的路径在梁处于原始位置时发生，并使悬臂梁偏转在悬臂模式中，屈曲梁以弯曲模式偏转，直到移动滑架的动能转换为梁的材料中的内部应力。由于这些内部应力，梁的反应运动被限制为通过屈曲梁的牵引作用返回到原始位置。在优选实施例中，闩锁壳体被实现为单件模制部件，并且部件的材料以及悬臂梁和弯曲梁的尺寸和形状都被选择以限制由于移动闩锁特征和闩锁到从原始位置到最大偏转位置的单个偏移并且返回到原始位置。
