Electronic key, in particular, for vehicles

摘要

The invention relates to an electronic key (10), in which coded signals (20) are transmitted and optionally received. In order to achieve this, it is necessary to provide suitable electronic components which are supplied with electric energy by a current reservoir in the housing interior (21). A mass (22) is kinetically mounted (24) in the housing interior (21), in order to ensure that the electronic key (10) is continuously operational. The kinetic energy (23) of said mass (22) which is generated when the key is moved, is converted into electric energy by an electric generator (26), provided in the housing interior (21). The electric energy is subsequently used to continuously recharge the current reservoir.
