Definitions
- the present invention relates to a key according to the preamble of claim 1.
- one or more batteries are present in the key handle in order to, for. B. to supply an integrated in the key handle transmitter and possibly a lighting device housed in the key handle with voltage.
- the power supply by means of batteries has the disadvantage that the vehicle doors cannot be unlocked and the lighting device cannot be used in the dark when the batteries are empty.
- Key devices have therefore been developed which are equipped with rechargeable energy stores and with charging contacts arranged on the key bit, in order to charge the rechargeable batteries with electrical energy from the vehicle electrical system while the key is in the steering starter lock.
- Such a key device is disclosed, for example, in DE-OS-37 38 568.
- the solution according to the invention is based on the fact that vehicle keys are often equipped with transponders for so-called immobilizers which have a transmitting and receiving part with which the energy of an alternating field can be received (cf. e.g. DE-A 35 36 377 ).
- the transmitting and receiving part is also used to power the transponder itself.
- a great advantage of this invention is that the transponder already contains a memory element and a rectifier circuit for its own energy supply, and this rectifier circuit can be used to rectify the charging current flowing into the energy store for supplying the consumers.
- the key 1 comprises a key handle 2 and a key bit 4.
- a rechargeable energy store 20 In a recess in the handle 2 there is a rechargeable energy store 20, a transponder 22, a transmitter 23, which can be, for example, an infrared transmitter for unlocking the vehicle doors, and a lighting device 27 housed.
- the transponder 22 In order to be able to charge the energy store 20, it is connected to the transponder 22 via lines 24.
- the lighting device 27 is connected to the energy store 20 via lines 28 and the transmitter 23 via lines 29.
- a transmitter coil attached to the vehicle emits an alternating field, which is generated by a coil of a transmitting and receiving part 26 of the Transponders 22 is received.
- the alternating field received by this coil is converted into a rectified voltage or a rectified current by means of a rectifier circuit integrated in the transponder 22.
- the rectified current then flows via lines 24 into the energy store 20 and charges it.
- the invention thus makes it possible that, even if power-intensive consumers are integrated in the key handle, it is not necessary to replace the energy stores. Additional functions, such as a lighting device and a remote control for central locking, can be accommodated in the key without increasing the storage capacity of the energy store 20.
