The invention discloses a safety device, a motor controller, a motor assembly and a vehicle, the safety device comprises a first conducting strip, the first conducting strip is provided with a first through hole penetrating through the first conducting strip in the thickness direction of the first conducting strip, and the first conducting strip forms a first weak part at the first through hole, the first weak part is configured to be broken when being impacted; a circuit board; and the Hall chip is arranged on the circuit board, a part of the Hall chip is arranged opposite to at least a part of the first through hole, or a part of the Hall chip is at least partially inserted into the first through hole. According to the safety device, the first through hole can serve as a broken hole of the first conducting strip to facilitate disconnection of the first conducting strip when current is abnormal, and the first through hole can serve as a sampling hole of the Hall chip to achieve dual purposes of the first through hole, so that the number of the first through holes is reduced, the first conducting strip is easy to machine, and the cost is reduced. The machining and production efficiency of the safety device is improved, and the production cost is reduced.

    本发明公开了一种保险装置、电机控制器、电机组件和车辆,所述保险装置包括:第一导电片,第一导电片上具有在第一导电片厚度方向贯穿第一导电片的第一通孔,第一导电片在第一通孔处形成为第一薄弱部,第一薄弱部被构造成在受到撞击时断开;电路板;霍尔芯片,霍尔芯片设于电路板上,部分霍尔芯片与至少部分第一通孔相对设置,或部分霍尔芯片至少部分插入第一通孔中。根据本发明的保险装置,使得第一通孔既可以成为第一导电片的断孔,便于电流异常时第一导电片的断开,且第一通孔又可以作为霍尔芯片的采样孔,实现第一通孔的一孔两用,从而减少第一通孔的设置,从而使得第一导电片加工简单,提高了保险装置的加工和生产效率,降低了生产成本。
