The invention relates to an automatic return safety handle assembly which comprises a handle body, a support, a circuit board, a driving mechanism and a transmission mechanism. The handle body can rotate relative to the support, the circuit board comprises a microcontroller module and a three-axis acceleration sensor module, and the three-axis acceleration sensor module is used for detecting the acceleration condition in the three-dimensional direction when the vehicle moves; when it is detected that the acceleration change meets the preset condition, the microcontroller module controls the driving mechanism to start working, and the driving mechanism drives the transmission mechanism to move and drives the handle body to rotate outwards so that the handle body can be in an unfolded state. According to the safety handle, whether the situation that a passenger is likely to be unbalanced occurs in the vehicle or not can be detected by detecting the acceleration change, when it is detected that the acceleration change meets the preset condition, namely the situation that the passenger is likely to be unbalanced occurs, the handle body is automatically unfolded, and the passenger holds the handle body at the first time to keep balance; and the passenger injury probability is reduced.

    本发明涉及一种自动回位安全拉手总成,包括拉手本体、支架、电路板、驱动机构、传动机构;拉手本体可相对支架转动,电路板包括微控制器模块以及三轴加速度传感器模块,三轴加速度传感器模块用于检测所在交通工具运动时三维方向的加速度情况;当检测到加速度变化符合预设条件时,微控制器模块控制驱动机构启动工作,驱动机构驱动传动机构运动并带动拉手本体向外旋转使拉手本体处于展开状态。本发明安全拉手可通过检测加速度变化来检测所在交通工具是否出现可能使乘客失衡的情况,当检测到加速度变化符合预设条件时,也即出现可能使乘客失衡的情况时,拉手本体自动展开,供乘客第一时间握持拉手本体以保持平衡,减少乘客受伤的几率。
