Description

FIELD The present application relates to the technical field of emergency stop of equipment, and in particular to an emergency stop button assembly and a charging pile. BACKGROUND An emergency stop button is used to cut off the power of the equipment connected to it, so as to protect the life and property of users. A conventional method for mounting the emergency stop button is to provide a mounting hole in the mounting plate of the equipment, and fix the emergency stop button in the mounting hole through nuts, however, with this mounting method, the emergency stop button is apt to be accidentally touched. In the conventional technology, the emergency stop button may be arranged in a mounting base which is welded to the mounting hole, so as to prevent the emergency stop button from being accidentally touched, however, this mounting method by welding requires a large amount of work and is inconvenient to disassemble. The patent of CN207082449U discloses a protection casing for an emergency stop button of a charging pile, including: a protection casing body and a connecting piece or member, the protection casing body is attached to the charging post to prevent the emergency stop button from being accidentally activated. The protection casing body has an urgent destruction piece which may be broken off by a user to reveal the emergency stop button. The patent of DE4101493A1 discloses an electrical emergency switching unit for use on machine systems which has an actuator stage and a contact module that is separate and is latched onto the lower section of the housing. The contact module has a pair of switch elements, one of which is a normally open type and the other normally closed. The actuator has a pin, which, when operated in an axial direction, acts against the switch element pins. The pins are spring biased in the vertical direction. If the actuator pin is damaged the switch elements adopt a failsafe position.
