The invention discloses a child bicycle brake handle assembly which mainly comprises a stay wire cavity formed by a base and an upper cover and a gear mechanism arranged in the stay wire cavity, the gear mechanism comprises a stay wire gear and a driving gear which are meshed with each other, the driving gear can be driven to rotate by pulling a handle part, and then the stay wire gear is driven to rotate. Therefore, an existing lever transmission mode is replaced with a gear transmission mode, and compared with the lever transmission mode, the gear transmission mode can transmit different torques by adjusting the size and the tooth number ratio of the gear, so that the transmission efficiency of the brake cable is improved, and the service life of the brake cable is prolonged. In this way, tensioning operation of the brake pad can be achieved under the small holding distance, the overall structure of the brake handle assembly is more compact and attractive, the brake handle assembly is more labor-saving, comfortable, flexible and safe to use, and the problem that an existing brake handle based on the lever principle cannot be better suitable for a child bicycle is solved.

    本发明公开了一种儿童自行车刹车手柄总成,该手柄总成主要包含由底座和上盖构成的拉线腔以及设置于拉线腔内的齿轮机构,齿轮机构包含相互啮合的拉线齿轮和驱动齿轮,拉动手柄部可带动驱动齿轮转动,进而驱动拉线齿轮旋转,拉线齿轮旋转即可带动刹车线收卷以对刹车片进行拉紧操作,可见,本申请采用齿轮传动方式代替了现有杠杆传动方式,相比杠杆传动方式,采用齿轮传动方式可以通过调节齿轮大小和齿数比即可传递不同的扭矩,如此不仅可在较小的握动距离下实现刹车片的拉紧操作,且使得刹车手柄总成的整体结构更加紧凑和美观,使用起来更加省力、舒适、灵活和安全,解决了现有基于杠杆原理的刹车手柄无法更好的适用于儿童自行车的问题。
