The present disclosure relates to a portable electronic device, in particular to a portable electronic device with a battery protection structure.

With the development of science and technology, many electronic devices (such as tablet computers or notebook computers) are quite popular nowadays. Since they can perform various functions, such electronic devices are gradually becoming popular among the public.

Generally speaking, a notebook computer is equipped with one or more battery modules for the normal operation of the notebook computer. In order to effectively utilize the internal space of the notebook computer casing, the battery module is generally arranged under the keyboard module or the touch panel. However, the thickness design of today's notebook computers tends to be thinner and lighter, resulting in that when the user presses the keyboard or touchpad, the casing of the notebook computer bends due to flexibility, so that the keyboard or touchpad flexes with the casing. The battery module is touched by bending, resulting in damage to the battery module.

Therefore, how to design a portable electronic device that prevents the battery module from being damaged is an issue worth discussing and solving.
