    Abstract: Provided is an electronic apparatus capable of suppressing damage to a chassis member even if a battery failure occurs. The electronic apparatus includes a first chassis member and a second chassis member, to which the first chassis member is detachably connected, and a battery. The electronic apparatus further includes a plurality of screws, which are provided along a first edge of the first chassis member and which fasten the first edge to the second chassis member, a first engagement piece provided on one end portion in the longitudinal direction of the second edge of the first chassis member, a second engagement piece provided on the other end portion in the longitudinal direction of the second edge, a first receiving part, which is provided on the second chassis member and with/from which the first engagement piece engages/disengages, and a second receiving part, which is provided on the second chassis member and with/from which the second engagement piece engages/disengages. The battery is placed at a position closer to the second edge than to the first edge in a chassis. The end surface of the first engagement piece and the end surface of the first receiving part each has a first slope surface. The end surface of the second engagement piece and the end surface of the second receiving part each has a second slope surface.

    Abstract: Embodiments of the present disclosure relate to the technical field of batteries, in particular, to a protection board, a battery and an electronic device. The protection board includes a protection board body and a flexible circuit board connected in sequence, where a puller assembly is provided on an end of the flexible circuit board away from the protection board body. In the present disclosure, since the puller assembly is arranged on the protection board, by means of directly grabbing the puller assembly, the battery can be disassembled or replaced, which avoids a safety risk of cracking of or damage to the flexible circuit board and thus seriously affecting the safety performance and service life of the battery due to directly taking the flexible circuit board with hands or devices.

    Abstract: The present application discloses a battery cell, a battery and an electrical device. The battery cell comprises an electrode assembly, a shell, a pressure relief mechanism and a support plate, wherein the shell is used for accommodating the electrode assembly and comprises a first side plate; the pressure relief mechanism is arranged on the first side plate and is configured to be actuated when the internal pressure of the battery cell reaches a first threshold, so as to release the internal pressure; the support plate is arranged between the first side plate and the electrode assembly; the support plate is provided with a weak portion which is opposite to the pressure relief mechanism in the thickness direction of the first side plate; the shape of the weak portion is the same as that of the outline of the pressure relief mechanism, and the external dimension of the weak portion is not greater than the dimension of the outline of the pressure relief mechanism; the support plate is configured to rupture along the weak portion when the internal pressure of the battery cell reaches a second threshold, so as to form a channel for guiding fluid to the pressure relief mechanism. The technical solutions in the embodiments of the present application can effectively improve the safety of battery cells.
