The invention discloses a self-heating subway handrail. The self-heating subway handrail comprises a foot plate arranged on the ground and a handrail body arranged underground. The lower side of the ground is provided with a cavity. The foot plate is provided with a groove. A lifting plate is slidably arranged in the groove. The lower sidewall of the lifting plate is fixedly connected with a fixedrod. An expansion spring is fixed between the lower end of the fixed rod and the inner bottom wall of the cavity. A coil is fixed to the end of the fixed rod. A magnet frame located on the outer sideof the coil is fixed to the interior of the cavity. The inner bottom wall of the cavity is provided with a storage capacitor connected with the coil. An electric heating wire is arranged in the handrail body. A trigger mechanism is buried in the ground. Through the self-heating subway handrail, when taking the subway, passengers go across the lifting plate to make the coil do cut magnetic induction line motion to generate electricity to be stored in the storage capacitor, and the electricity required for operation of the electric heating wire is increased. When the air temperature is low, twoelectric contact pieces make contact to drive the electric heating wire to work so that the passengers cannot feel cold and discomfortable when holding the handrail in a cold environment.

    本发明公开了一种自热地铁扶手,包括设置在地面上的踩板和设置在地面下的扶手,所述地面下侧开设有腔体,所述踩板上开设有凹槽,所述凹槽内滑动有升降板,所述升降板的下侧壁固定连接有固定杆,所述固定杆的下端与腔体内底壁之间固定有伸缩弹簧,所述固定杆的端部固定有线圈,所述腔体内固定有位于线圈外侧的磁铁框,所述腔体内底壁设有与线圈连接的蓄电容,所述扶手内设置有电加热丝,所述地面内还埋设有触发机构。本发明通过乘客乘坐地铁时走过升降板使线圈做切割磁感线运动,产生电量储存在蓄电容内,提高电加热丝工作所需电量,当气温较低时两电触片相接触使电加热丝进行工作,避免扶手在寒冷环境中冰凉不适。
