Abstract
The application relates to an energy accumulator and a vehicle, the energy accumulator comprising a shell with an inner cavity, a diaphragm, a snap ring and a limiting piece which are arranged in the inner cavity; the diaphragm divides the inner cavity into a first cavity and a second cavity, and the diaphragm has a peripheral edge part close to the peripheral line of the diaphragm; a part of the outer peripheral surface of the snap ring is connected with the shell, and the other part of the outer peripheral surface of the snap ring is clamped with the shell to clamp the peripheral edge part; the limiting piece is located at the end of the snap ring away from the second cavity and is in contact with the end surface of the snap ring away from the second cavity; the snap ring has a first inner peripheral surface, the shell has a first surface for defining the first cavity, the limiting piece has a limiting surface away from the first surface, and the first inner peripheral surface is smoothly connected to the limiting surface. According to the above scheme, the corner space between the snap ring and the shell can be eliminated, the deformation of the diaphragm to the corner space between the snap ring and the shell can be avoided, the stretching degree of the diaphragm can be limited, and the excessive stretching of the diaphragm can be avoided. In this way, the service life of the diaphragm can be prolonged.
