The invention provides a vibration energy collecting device, a train running state monitoring system and a train, and relates to the technical field of vehicles. The device is used for collecting transverse vibration energy, the vibration energy collecting device comprises an outer sleeve, an inner sleeve, a fixed magnet, a coil and elastic mechanisms, the fixed magnet is fixed to the outer sleeve, the coil is fixed to the inner portion of the inner sleeve, the inner sleeve is installed on the outer sleeve in a sliding mode, and the elastic mechanisms are arranged between the same side ends of the inner sleeve and the outer sleeve respectively. The elastic mechanism comprises a magnetic spring and a linear spring. Wherein the two ends of the inner sleeve are each provided with an elastic mechanism, and under external vibration, the elastic mechanisms drive the inner sleeve to slide in the outer sleeve, so that the coil cuts magnetic induction lines and collects electric energy in a fixed magnetic field generated by the fixed magnet. Therefore, low-frequency vibration energy can be collected, and the low-frequency energy collection requirement of self vibration in the train running process is met.
本发明提供一种振动能量收集装置、列车运行状态监测系统及列车,涉及车辆技术领域。该装置用于收集横向振动能量,振动能量收集装置包括外套筒、内套筒、固定磁铁、线圈及弹性机构,固定磁铁固定于外套筒,线圈固定于内套筒的内部,内套筒可滑动安装于外套筒,内套筒和外套筒的同侧端之间分别设有弹性机构,其中,弹性机构包括磁力弹簧及线性弹簧。其中,内套筒的两端均设有弹性机构,在外部振动下,弹性机构带动内套筒在外套筒内滑动,从而使线圈在固定磁铁产生的固定磁场内切割磁感线,收集电能,相比于现有的能量收集装置,弹性机构包括磁力弹簧和线性弹簧,从而能够收集低频振动能量,满足列车运行过程中自身振动的低频能量收集要求。
