Abstract: The present disclosure provides a pressure relief valve configured to adjust a pressure of a vehicle cabin. The pressure relief valve includes: a housing, a passage opening cover, and an implementing mechanism. The housing is provided with a passage therein, the passage is configured to be capable of bringing the vehicle cabin into fluid communication with an outside atmosphere, and the passage has a passage opening. The passage opening cover is configured to be movable between an open position and a closed position, the passage opening is open when the passage opening cover is in the open position, and the passage opening is closed when the passage opening cover is in the closed position. The implementing mechanism is configured to drive the passage opening cover such that the passage opening cover is movable between the open position and the closed position.

Abstract: A mounting seat for a pressure relief device. The mounting seat comprises a main body portion, a blocking portion and a lug. The main body portion has a circular cross section. The blocking portion is circumferentially arranged on an outer surface of the main body portion and is formed by extending outward from the outer surface of the main body portion. The lug is located below the blocking portion and is separated from the blocking portion by a distance, and the lug extends outward from the outer surface of the main body portion. The pressure relief device of the present application, through its rotation, may be securely mounted to a housing of the battery pack, without requiring additional mounting parts and tools, which greatly simplifies the mounting process of the battery pack.

Abstract: A pressure relief device includes a mounting seat, a valve core, and a pressure relief member. The mounting seat is internally provided with a fluid channel, and the fluid channel is capable of communicating with an internal space of a component to be subject to pressure relief. The valve core is arranged to be aligned with the fluid channel in the mounting seat, and a pressure relief channel is formed between an outer edge of the valve core and an inner wall of the fluid channel of the mounting seat. The pressure relief member is sleeved on the outer edge of the valve core and is deformable and configured to open and close the pressure relief channel by means of its deformation. The pressure relief device of the present application utilizes the deformable property of the pressure relief member to achieve the effect of repeated use and multiple pressure reliefs of the pressure relief device.
