The invention relates to the technical field of electric vehicles. The invention further discloses an electric vehicle anti-collision speed reduction device based on the piezoresistor. The device comprises a shell I and a shell II, the outer part of the shell I is movably connected with a soft shell; an ejector rod is fixedly connected to the exterior of the soft shell, a clamping block is fixedlyconnected to the exterior of the ejector rod, a clamping rod is movably connected to the exterior of the clamping block, a first spring is movably connected to the exterior of the clamping rod, a dielectric plate is movably connected to the interior of the ejector rod, a positive plate is movably connected to the interior of the first shell, and a negative plate is movably connected to the interior of the first shell; under the interaction of the shell I, the soft shell, the ejector rod, the clamping block, the clamping rod, the spring I, a dielectric plate, a positive plate, a negative plate, an electromagnet I and a piezoresistor, when the electric vehicle is subjected to large external acting force in the running process, the speed limiting device can be controlled to be started later,and therefore body injuries, caused by large inertia speed, of a driver can be reduced.

    本发明涉及电动车的技术领域,且公开了一种基于压敏电阻的电动车防撞减速装置,包括外壳一和外壳二,所述外壳一的外部活动连接有软壳,软壳的外部固定连接有顶杆,顶杆的外部固定连接有卡块,卡块的外部活动连接有卡杆,卡杆的外部活动连接有弹簧一,顶杆的内部活动连接有电介质板,外壳一的内部活动连接有正极板,外壳一内部活动连接有负极板;通过外壳一、软壳、顶杆、卡块、卡杆、弹簧一、电介质板、正极板、负极板、电磁铁一、压敏电阻之间的相互作用下,可以使得电动车在行驶过程中遭受到外界较大的作用力时,会控制之后的限速装置启动,这样就可以降低驾驶者由于受到较大的惯性速度造成的身体伤害。
