The invention discloses an adjustable brake system of an electric bicycle trailer. The adjustable brake system comprises a shell, a spring shock absorber is fixed to the rear end of the shell, an oil pressure brake device located in front of the spring shock absorber is fixed in the shell, a universal joint is fixed to the front end of the shell, and the oil pressure brake device is connected with a brake caliper installed on a wheel of the trailer through an oil pipe. The spring shock absorber is composed of an end cover, a spring, a middle shaft and a fixing sleeve, the middle shaft is sleeved with the spring, a through hole allowing the front end of the middle shaft to stretch out is formed in the center of the end cover, the oil pressure brake device comprises a piston and a piston rod connected with the piston, the piston rod extends front and back, and the rear end of the piston rod is connected with the front end of the middle shaft. After the electric bicycle is braked, the trailer continues to move forwards through inertia, the trailer pushes the middle shaft to move forwards, the spring is compressed, the oil pressure brake device is triggered after the middle shaft moves forwards, brake calipers installed on wheels of the trailer work to generate brake force, and the trailer is braked.

    本发明公开了一种可调节电动自行车拖车刹车系统,包括外壳,外壳后端固定有一弹簧减震器,外壳内固定有一位于弹簧减震器前方的油压刹车装置,外壳前端固定有一万向节,油压刹车装置通过油管连接有安装在拖车车轮上的刹车钳;弹簧减震器由端盖、弹簧、中轴、固定套组成,弹簧套在中轴外,端盖中心具有供中轴前端伸出的通孔,油压刹车装置包括活塞以及与活塞相连的活塞杆,活塞杆前后延伸且其后端与中轴前端连接。当电动自行车刹车之后,拖车通过惯性继续向前移动,拖车推动中轴向前移动,弹簧被压缩,中轴向前移动后会触发油压刹车装置,使得安装在拖车车轮上的刹车钳工作产生制动力,将拖车刹住。
