Key function conversion method, key function conversion device and electronic equipment

A key function conversion device comprising:

• a detecting module, designed to detect a click operation sent by a first key on a keyboard or keypad of a device, wherein the device has corresponding ID information thereof;
• a converting module, designed to search for a second key associated to the first key in a key mapping table and convert the click operation sent by the first key into a click operation sent by the second key, wherein the key mapping table is searched for based on a match with the ID information of the device, and a determination of the existence of the key mapping table matching the device ID information is made, wherein if the key mapping table matching the device ID information exists, the key mapping table matching the device ID information is imported into a memory of the device, and wherein, if the key mapping table matching the device ID information does not exist, the key mapping table is requested from a server through a network connection;
• a generating module, designed to generate a function trigger signal corresponding to the click operation sent by the second key.
