Definitions

  • the invention relates to a switching device with the features of the preamble of patent claim 1.
  • this known switching device for switching on the heating current has the disadvantage that it is susceptible to faults and that, for example, under extreme environmental conditions, for example in the case of completely iced locks, a switch actuation using the key is no longer possible at all.
  • the invention has for its object to provide an improved switching device by means of which a contactless, controllable switching of electrical circuits is made possible, in particular a function of this switching device itself extreme external conditions, especially temperature conditions, should be guaranteed.
  • a switching device of the type in question on a manually operable, in particular actuatable with the aid of a key, switch and instead provide at least one magnetically actuated switch which, for example, directly behind a glass pane, e.g. B. a vehicle door, arranged and then can be set from the outside with the help of the associated actuating magnet in or out of function.
  • a glass pane e.g. B. a vehicle door
  • the switching device preferably has at least one switch in the manner of a reed relay.
  • the switching device has a corresponding number, preferably one below the other modified switches, which are arranged together quasi in the form of a matrix and each can be actuated individually by an associated actuating magnet.
  • the matrix with the individual, magnetically actuated switches can be arranged in a visible manner, for example directly behind a glass pane, for example a vehicle, in particular a motor vehicle, so that the desired switch actuation is easily ensured from outside the vehicle.
  • a special magnetically operable switch is integrated in the trunk lid lock or glove box lock, which can only be actuated in a coded manner with the aid of an associated magnet, which means nothing more than that only when the correct magnet is used the trunk lid lock or the glove box lock can also be opened.
  • the associated vehicle keys can easily be handed over to the corresponding parking attendant or a corresponding person, without the possibility that the parking attendant has access to the luggage in the trunk or the like.
  • a switching device 1 shown in FIG. 1 for contactless, controllable switching of a circuit for an electric door lock deicing system essentially has a reed relay 2, in which two magnetizable, movable contacts 7 and 8 are melted within a glass tube 9, as is the case with this is already known in a reed relay.
  • a connecting line 10 leads from one contact 7 to a connection of a heating resistor 5, while a line leads from the other connection of this heating resistor 11 leads to an accumulator 13. From this accumulator 13, a further line 12 to the second contact 8 of the reed relay 2 is provided.
  • the heating resistor 5, which can be a PTC thermistor, for example, is embedded within a heat-conducting, but electrically non-conductive body 6 which is in direct contact with a partial surface area of a locking cylinder 14 of a motor vehicle door lock.
  • 2 shows, for example in a partial side view, a motor vehicle body 15 with a vehicle door which has a glass pane 16 in a known manner and a door handle 17 with a door lock, to which the locking cylinder 14 belongs.
  • the reed relay 2 is arranged directly on the inside of the vehicle door glass pane 16 in an area above the door lock.
  • the switching device for the door lock deicing system also includes an actuating magnet 3, in particular in the form of a permanent magnet, which is specifically assigned to the reed relay 2 and is used in a known manner to trigger the switching process.
  • this actuating magnet 3 can either be accommodated in a key head of the vehicle door key or else in a vehicle door key tag, as is not shown in detail in the drawing.
  • the user now wants to put the door lock deicing system into operation he approaches the actuating magnet 3 to the reed relay 2 located behind the glass pane 16, so that when a certain, predetermined distance between the actuating magnet 3 and the reed relay 2 is reached, a contact actuation is effected host, ie a closing of the two magnetizable contacts 7 and 8 as long as the actuating magnet 3 is held in this position will.
  • the accumulator 13 supplies the heating resistor 5 of the door lock de-icing system with current, so that there is a corresponding heating of the heat-conducting body 6, which ultimately leads to a corresponding heating of the locking cylinder 14 and thus to its de-icing or de-icing Door lock leads.
  • FIG. 3 shows an embodiment of the switching device according to the invention, in which a predetermined number of switches 2 are arranged in the form of a matrix on a type of switch panel 18, each switch being a reed relay 2, as in FIG Fig. 1 shown.
  • these reed relays 2 are preferably modified with respect to one another in such a way that each individual reed relay 2 can be actuated individually, for which purpose corresponding actuating magnets 3 must be provided, as is not shown in FIG. 3 for the sake of simplicity.
  • Such a switch matrix or switch panel 18 can, for example, also be attached directly behind a glass pane of a motor vehicle, so that in In this case, a corresponding number of different elements or units within the motor vehicle can be switched on and off individually with the aid of the respectively assigned actuating magnet, preferably a coded mutual assignment between each individual reed relay 2 on the matrix 18 and each individual actuating magnet 3 is provided.
  • Such a magnetically actuated switchgear is secured against unauthorized interference by third parties.
  • the switching device according to the invention except z. B. in motor vehicle door lock deicing systems can also be installed in general for vehicle and front door locks.
