The invention discloses an electric scooter hub brake. The electric scooter hub brake comprises a shoe block set, a rocker arm set and a hub cover set, wherein a crank throw is arranged to be of a hidden honeycomb drop-shaped structure, a rotating shaft is arranged at one end of the crank throw, a wire pressing plate assembly is arranged at the other end of the crank throw, the end of a crank throw body is an annular cylinder supporting piece, the tail of the crank throw body is a semi-surrounding type stress receding piece, the crank throw is sequentially arranged from wide to narrow from the end of the main body to the tail of the main body, the wire pressing plate assembly is arranged at one end of the semi-surrounding type stress receding piece, at least three special-shaped grooves are formed in a crank throw main body, the crank throw is fixed to the end face of a brake box body through a rotating shaft, a rotating hole is formed in the rotating shaft, the rotating angle of the crank throw is not exposed out of the brake box aluminum body within an allowable range, so that the crank throw is not easy to damage, and an anti-collision effect is achieved; and in the stretching process, a wire pressing block and a through shaft are not prone to colliding, a gap is small, space is saved, the space is compact, the appearance is attractive, the applicability is wider, a brake cable is pulled more smoothly, stress is even, strength is high, the braking effect is better, and brake reset is flexible and free.
本发明公开一种电动滑板车毂闸,它包括蹄块组、摇臂组和毂盖组,曲拐设置为隐藏型蜂窝滴状结构,曲拐一端设有转动轴,另一端设有压线板组件,曲拐主体端部为环形圆筒支撑件,曲拐主体尾部为半包围式受力让位件,曲拐从主体端部到主体尾部依次由宽到窄设置,压线板组件设置于半包围式受力让位件一端,曲拐主体开设有至少三个异型槽,曲拐通过转动轴固定在闸盒本体端面,转动轴上设有转动孔,曲拐转动角度在允许范围内不外露于闸盒铝本体外部,使得曲拐不易损坏,起到防撞的作用;在拉伸过程中压线块与通轴不易碰撞,间隙小,节约空间,空间紧凑,外形美观,适用性更广,刹车线拉动更为顺畅,受力均匀,强度高,制动效果更好,刹车复位灵活自如。
