Description

Technical Field

[0001] The utility model relates to the technical field of battery compartments, in particular to a battery compartment for preventing upper and lower double-layer batteries from short circuiting. Background Art

[0002] The battery compartment structure has been widely used in various fields. The current battery compartment basically places the battery directly into the corresponding battery compartment in the machine body, and then installs the battery cover to seal the battery.

[0003] The above method generally marks the positive and negative poles on the battery compartment to tell the user the direction of installing the battery.

[0004] If the user installs both the upper and lower batteries upside down and then presses the power button, the internal components of the device may burn out.
