Abstract: The present disclosure proposes a keybed device, including: a keybed support; a keybed arranged on the keybed support; a key height limiting column arranged in one-to-one correspondence with each key in the keybed, and an end of the key height limiting column is fixed on a bottom surface of the corresponding key; a pressure detecting device arranged in one-to-one correspondence under each key height limiting column to detect a pressing strength of each key height limiting column; and a flexible support structure arranged below each key height limiting column and located on at least one side of each pressure detection device. The keybed device includes a flexible support structure, which can avoid false triggering of the Aftertouch effect. A same depth is pressed down from the flexible support structure to obtain a consistent Aftertouch effect, and the performance effect is controllable.

Abstract: The present disclosure discloses a shoe with charging function, including a shoe body, an electricity generating apparatus, a battery, and an output interface, wherein: the electricity generating apparatus is configured to convert work done by a pressure applied to the apparatus into electrical energy, is mounted at the heel of the shoe body and electrically connected to the battery; and the battery is mounted at the counter of the shoe body and configured to connect the output interface for connecting a charging wire. In a process of running or walking, the shoe with charging function converts work done by a pressure applied to the apparatus into electrical energy stored by a battery, thereby eliminating certain defects of conventional charging manners, and meantime charging a mobile terminal. In periods of not being charged, surplus electrical energy is stored in the battery, environment-friendly, safe, and convenient.
