This application provides a fireproof component, a battery pack, and a device using the battery pack as a power supply. The fireproof component includes a main body and a frame. The frame includes a body portion, an extension portion, and an opening defined by an inner peripheral face of the body portion. The extension portion is located circumferentially outside the body portion and connected to the body portion. The extension portion extends along a third direction that is perpendicular to a plane defined by the frame and protrudes beyond the body portion. The main body covers the opening of the frame and is connected to the body portion. The main body and the frame of the fireproof component are parts independent of each other, and therefore, can be made of different materials and in different molding processes.

Fireproof component, battery pack, and device using battery as power supply

The embodiments of the present application provide a frame body, a battery pack, and a device. The frame body used for a battery pack includes a first bracket comprising a first mold chamber; a second bracket connected end to end with the first bracket to form a receiving cavity, the second bracket comprising a second mold chamber; and a block comprising a first reinforcement portion and a second reinforcement portion, wherein the first reinforcement portion received in the first mold chamber and the second reinforcement portion received in the second mold chamber, and the block is adapted to connect the first bracket with the second bracket. The frame body is provided with a block at a connecting portion of the first bracket and the second bracket, thereby improving a connection strength and rigidity of the frame body and the overall bearing capacity of the lower housing including the frame body.
