Definitions

  • the invention relates to an electronic key for actuating a lock with the features of the preamble of claim 1.
  • the doors are often equipped with a central locking system, the locks of the doors being remotely controllable by means of an electronic key using infrared or RF radiation to increase comfort.
  • a car door is usually provided with an additional mechanical lock for opening the door, which can be actuated by means of an additional mechanical key. This ensures that at least one lock for opening the door can also be operated if the electronic key fails, for example when the energy store is empty.
  • the older patent application P 44 44 913.5 is based on the task of further developing a key in such a way that the operational security for the emergency key is improved.
  • the emergency key is designed as a separate key and that the housing contains a receptacle for the emergency key, into which the latter can be inserted.
  • the invention is based on the object of creating an electronic key which also has an additional mechanical key bit and in which the key housing is designed to be user-friendly and visually appealing.
  • the position of the active part of the electronic key can be immediately identified by haptic action.
  • the key is visually very appealing. It can be constructed with a small thickness, in particular if the mechanical key is installed in an upright manner in the housing.
  • the key according to the invention has large, uninterrupted surfaces on the sides and thus has only a few or no sharp edges, so that it does not pose any risk of damage to jacket pockets, etc. Operating elements of different sizes and their handling symbols can be clearly displayed on these surfaces. To make it easier to find the individual operating elements in the dark, markings, for example webs, grooves or the like, can be provided on the housing surface between the operating elements. Display elements and setting elements for storing memo data can also be accommodated on the side surfaces. Further refinements and advantages result from the description of exemplary embodiments and the subclaims.
  • Fig. 1 shows a key according to the invention in perspective
  • Fig. 2 is a plan view of the back of the electronic key
  • FIG. 3 and FIG. 4 are perspective representations of further training Fig. 5 and Fig. 6 partial representations of sections through the housing of the electronic key.
  • the housing of the electronic key is shown at 1. It is wedge-shaped.
  • the right narrow end 2 of the wedge is inserted into the lock to be operated e.g. inserted into the ignition lock of a vehicle. You can see the small thickness of the case compared to the other dimensions, which is pleasant when worn.
  • the housing 1 contains a circuit board, not shown. There is an electronic circuit on this circuit board, which is designed, for example, as an integrated circuit. This electronic circuit is fed by an energy store, for example a battery or a rechargeable battery, and is used to operate the electronic key. A transmitting element and a receiving element are arranged on the front side 2 of the housing 1.
  • the transmitting element and the receiving element can work by means of infrared radiation, RF radiation or the like.
  • a code is generated in the electronic circuit of the key, which code is sent out via the transmission element in the manner of a unidirectional communication.
  • This code is picked up by a corresponding receiver on the motor vehicle, decrypted and the user authorization is analyzed. If the user authorization is correct, the corresponding function is carried out on the central locking of the door locks.
  • a code for example in the manner of bidirectional communication, is exchanged with corresponding transmission and reception elements of the ignition lock via the transmission element and the reception element. In this case, the user authorization is again analyzed and, if the key is correct, the ignition lock can be operated, for example in the usual way, and the motor vehicle is started up.
  • a unique identifier for the respective motor vehicle is stored in the electronic circuit of the key as an individual identifier.
  • This individual identifier can be, for example, a unique number assigned by the motor vehicle manufacturer.
  • the same individual identifier is also stored in the ignition lock. If the key is inserted into the ignition lock, the individual identifier is identified.
  • a random number is first determined as a key figure in the ignition lock by means of a random number generator and stored in the ignition lock. From this key figure, a code is formed in the electronics of the ignition lock based on a defined algorithm, which is transmitted as a second operating signal from the transmission element of the ignition lock to the reception element of the key. This received by the receiving element of the key second operating signal is in the electronic circuit of the key decrypted using the algorithm in the key figure. This characteristic number and the individual identifier stored in the electronic circuit of the final ice are now used to form a coded first operating signal in the electronic circuit of the final ice using the specified algorithm. At the same time, the key figure is stored in the electronic circuit of the key. This first operating signal is then transmitted from the transmission element of the key to the ignition lock.
  • the first operating signal is then decrypted in the electronic circuit of the ignition lock in accordance with the specified algorithm, which results in a determined key figure and a determined individual identifier.
  • a comparison is then made between the determined individual identifier and the identified key figure with the individual identifier and key figure stored in the ignition lock. If this comparison is positive, i.e. if it is the correct individual identifier and code, the user authorization is given. This will e.g. the immobilizer is released and the vehicle is put into operation.
  • a third operating signal was formed and sent using a specified algorithm.
  • the third recorded by the receiver on the motor vehicle The operating signal is passed on to electronics, for example those in the ignition lock, and decrypted there using the stored code and the specified algorithm.
  • the result of the decryption results in a determined individual identifier.
  • the determined individual identifier is compared with the individual identifier stored in the electronics and, if there is a match, the central locking is unlocked or locked.
  • Fig. 1 there are further push buttons 4 and 5 and a slide switch 6 for triggering further operating functions, e.g. intended to trigger an alarm. If the vehicle is equipped accordingly, an alarm message by radio can also include the location of the vehicle.
  • the housing 1 also contains a sliding key, which is accommodated in a receptacle 7 on the upper part of the housing 1. It can be pushed out of the receptacle 7 to the right with an actuating lever 8.
  • the housing 1 contains a slot 9 for the actuating lever 8 at the top.
  • the slot 9 can have an elastic lip which normally seals it, but evades the actuating lever when the sliding key is moved.
  • the housing contains stops and catches at the two end positions of the key to secure the mechanical key.
  • the housing 1 is rounded at the left wide end to avoid sharp edges and to make the shape more appealing.
  • the lever 8 contains an opening 10 for hanging the removed (separated) mechanical key on a keychain.
  • the housing 1 can have an eyelet in order to be able to hang up or hang up the entire key.
  • Fig. 1 display elements 12 are still drawn in to indicate any status of the system (e.g. battery charge or location).
  • a movable stop can be removed with an actuating knob 11 in order to be able to remove the key from the receptacle 7.
  • This is of particular interest when designing the key, including a remote control, because in this case the mechanical key, which is (also) suitable for locking the trunk, can be taken by the driver while the workshop or the porter takes the electronic key to move the Vehicle.
  • Fig. 2 shows the back of the key housing 1.
  • two turntables 13 and 14 provided with symbols (numbers, letters) are accommodated under the surface of the housing.
  • the turntables step outwards and can be turned by hand.
  • the set symbols can be seen on windows 16. You can e.g. identify the parking lot number or the room number of the hotel.
  • the housing is designed in appropriate colors and is supplied in different colors for men and women, for example.
  • the housing is preferably formed in two parts.
  • FIG. 3 shows a wedge wrench in which the mechanical key 20 is connected to the housing 21 so that it can be folded out.
  • Fig. 4 again shows a wedge key with a mechanical key, which is designed as a sliding key.
  • the sliding key is arranged upright in the housing, which can be recognized by the correspondingly designed receptacle 23.
  • This solution enables the housing to be made very thin. It is particularly applicable to electronic keys that do not include a remote control and therefore do not require their own energy source (battery) (when used as an ignition key, the energy is transferred from the lock to the key) and for which therefore the space for the active narrow side 24 such an arrangement of the mechanical key is present.
  • battery battery
  • a stop 31 is pulled downwards with the aid of a knob 32 against the force of a spring 33.
  • the mechanical key can now be pulled out to the left.
  • the actuating lever 26 can be made of high-strength plastic.
  • a key ring is indicated at 34, on which the electronic key as a whole or only the mechanical key can be attached.
  • part of the mechanical key 35 is again shown with its actuating lever 36.
  • a displaceable stop 37 is also provided here.
  • the detent is realized by a bulge 38 on the actuating lever 36 and a recess in the housing 39. Through the recess 40, the actuating lever 36 made of plastic is resilient at this point, so that the bulge 38 can be pushed out of the recess.
