Abstract: An end cover assembly, an energy-storage apparatus, and an electricity-consumption device are provided. The end cover assembly includes an end cover, an insulating member, a positive pole, a negative pole, a first connecting member, and a second connecting member. The insulating member and the end cover are stacked in a first direction. The insulating member includes a first separate member, a second separate member, a third separate member, and a fourth separate member. The third separate member, the first separate member, and the second separate member cooperatively define a first accommodating space. The fourth separate member, the first separate member, and the second separate member cooperatively define a second accommodating space. The positive pole penetrates through the third separate member and the end cover. The negative pole penetrates through the fourth separate member and the end cover.

Abstract: An adapter assembly, an energy storage device and a power consuming apparatus are provided. The adapter assembly includes an adapter and a limiting member. The adapter includes a first connecting portion, a second connecting portion, and a bendable connecting portion connected between the first connecting portion and the second connecting portion. The limiting member is located between the first connecting portion and the second connecting portion foldable with respect to each other, and is insulated from the adapter. The limiting member has a limiting face configured to abut against the bendable connecting portion, and the bendable connecting portion is configured to rotate and bend around the limiting face.

Abstract: A motor, including: a rotational shaft, a rotor, a stator, a housing, a first end cover, and a second end cover. The first end cover includes: a cover body including a bottom surface and a top surface, a bearing cavity, and a plurality of first bosses. The rotor is mounted on the rotational shaft; the stator is nested and installed inside the housing. The rotor is nested inside the stator; the first end cover and the second end cover are disposed on a rear end and a front end of the housing, respectively. The bearing cavity is disposed in the middle of the bottom surface of the cover body. The first bosses are circumferentially disposed at intervals on the top surface of the cover body. Outer side surfaces of the first bosses are located on a circle having a circle center coincident with the center of the cover body.

Abstract: A Montgomery modular multiplication device and an embedded security chip. The Montgomery modular multiplication device includes a first Montgomery modular multiplication module, a power calculation module and a second Montgomery modular multiplication module. The first Montgomery modular multiplication module obtains a first operation result A according to two first preset parameters. The power calculation module obtains a second operation result B according to the first operation result A output by the first Montgomery modular multiplication module, the first preset parameters, the second preset parameter and a power calculation function. The first Montgomery modular multiplication module further obtains a Montgomery modular multiplication conversion coefficient according to the first operation result A and the second operation result B.
