Described herein are brake assemblies that can be used in window shades including spring-balanced window shades, such as spring-balanced motorized window shades. The brake assembly includes a wire brake spring forming a plurality of coils. The plurality of coils may terminate in a tang assembly having a tang and a support portion. The support portion supports the tang when a force (e.g., a spring tightening force or a spring loosening force) acts on the tang. Since the tang is supported at each of its ends, the support portion greatly reduces the risk of bending of the tang. The brake spring may use a smaller wire diameter with a smaller likelihood of bending of the tang, which results in a smaller resistance when the brake spring is rotated in a driven state. In the case of a battery-driven window shade, the battery life is saved with less resistance.
本文中描述制动组件，所述制动组件可用于包括弹簧平衡式遮光帘的窗帘，诸如弹簧平衡式电动窗帘。所述制动组件包括形成多个线圈的线材制制动弹簧。所述多个线圈可终止于柄脚组件，所述柄脚组件具有柄脚和支撑部分。当力(例如，弹簧收紧力或弹簧松开力)作用于所述柄脚时，支撑部分支撑所述柄脚。由于所述柄脚支撑在其端部中的每一者处，因此所述支撑部分极大地减小所述柄脚弯曲的风险。在所述柄脚弯曲的可能性较小的情况下，所述制动弹簧可使用较小的线材直径，这会在所述制动弹簧在受驱动状态下旋转时产生较小的阻力。在电池驱动遮光帘的情形下，较小的阻力节省电池寿命。
