When the battery is pushed into the battery compartment, the swing arm slides from a first inclined surface to an adjacent lower second inclined surface and the battery is pressed against the at least one elastic member, and the at least one elastic member occurs when the external thrust disappears. The deformation generates an elastic force, so that the swing arm continues to slide from the second inclined surface to the adjacent lower third inclined surface, and the swing arm slides to the apex angle of the convex portion of more than 180 degrees to catch the battery in the battery compartment; When the stuck battery is pushed again, the battery is pressed against the at least one elastic member to generate an elastic force, and the swing arm is further pushed to slide from the third inclined surface to the adjacent lower fourth inclined surface, and the battery is automatically driven from the battery compartment. pop up.

The invention relates to an electronic device for automatically loading and unloading a battery. When the battery is inserted into the battery compartment, the swing arm slides along a sliding slope to a vertex of a bump, thereby automatically clamping the battery. The battery is in the battery compartment; when the battery is unloaded, as long as the outside pushes the battery stuck in the battery compartment, the spring deformation generates a spring force to push the swing arm away from the apex, and continues to slide to the lower slope, so that the battery automatically pops out from the battery compartment. . The battery compartment of the electronic device of the invention has a simple structure and is relatively simple to operate when the user handles the battery.
