The invention relates to the technical field of electric vehicles, and discloses an electric vehicle stall protection device capable of automatically decelerating. The device comprises a rotating shaft, a shell fixedly sleeves the rotating shaft, a connecting pipe is fixedly connected to the interior of the shell, a connecting rod is movably connected to the interior of the connecting pipe, and abalancing weight is fixedly connected to the exterior of the connecting rod. A copper rod is fixedly connected to the interior of the balancing weight, an N pole is fixedly connected to the interior of the shell, an S pole is fixedly connected to the interior of the shell, and a second spring is movably connected to the interior of the shell. When the rotating shaft is in a normal rotating speed state, through the interaction among the rotating shaft, an electric wire, a spring I, a movable block and an electrorheological body, the rotating shaft does not influence the normal use of the electric vehicle when being in a normal rotating speed range, so that the situation that the use of a stall protection device limits the normal use of the electric vehicle is avoided, and the electric vehicle can meet the requirement of daily use.

    本发明涉及电动汽车技术领域,且公开了一种能够自动减速的电动汽车失速保护装置,包括转轴,所述转轴的外部固定套接有外壳,外壳的内部固定连接有连接管,连接管的内部活动连接有连接杆,连接杆的外部固定连接有配重块,配重块的内部固定连接有铜棒,外壳的内部固定连接有N极,外壳的内部固定连接有S极,外壳的内部活动连接有弹簧二,转轴处于正常转速状态时;通过转轴、电线、弹簧一、活动块、电流变体之间的相互作用,可以使得转轴在正常转速范围内时不会对电动汽车的正常使用产生任何影响,避免了失速保护装置的使用给电动汽车的正常使用带来限制的情况发生,从而使得电动汽车能够符合日常使用的需要。
