The invention discloses a carbon fiber bicycle frame damage alarm device and circuit, comprising a frame, a metal woven net embedded between the inner and outer walls of the frame, the metal woven net being equivalent to a resistor R1, the resistor R1 being electrically connected with a resistor R2, the resistor R3 being electrically connected with a resistor R4, and an alarm assembly for warning the damage state of the frame, the alarm assembly comprises an alarm lamp and a triode. According to the scheme, real-time alarming can be achieved, a user is facilitated to avoid dangers, a detection alarming circuit adopts a comparison circuit without a sampling measurement link, the cost is lower, the detection alarming circuit is simple and more reliable in structure, easy to miniaturize and capable of being directly fused with a frame, the influence on the pneumatic design of the frame is extremely small, meanwhile, the weight of the frame is slightly increased, and the cost is reduced. The strength of the frame is basically not affected, the intrinsic conductivity of the frame fluctuates greatly, standardized evaluation can be established by adopting an evaluation layer mode of the scheme, and industrial production is facilitated.

    本发明公开了一种碳纤维自行车架损伤告警装置及电路,包括车架,金属织网嵌设于车架内外壁之间,金属织网等效为R1电阻,R1电阻与R2电阻之间相互电性连接,R3电阻与R4电阻之间相互电性连接,报警组件,用于对车架的损伤状态进行警示,报警组件包括警示灯与三极管。本方案可以实现实时报警,有利于用户避免危险,检测告警电路采用对比电路,不经过采样测量环节,成本更低,检测告警电路结构简单更加可靠且易于小型化,可直接与车架融合,对车架自身的气动设计影响极小,同时很少增加车架重量,基本不影响车架强度,车架本生电导率波动很大,采用本方案的评估层方式可建立标准化评估,便于工业生产。
