Definitions

  • the invention relates to a heatable door cylinder, in particular for motor vehicle doors, with an electrical heating device and a switch provided for actuating it.
  • a heating cartridge with an ohmic resistance which is inserted into a recess in the cylinder housing, has been used as the heating element.
  • Such a heating cartridge is inevitably dimensioned large and thus takes up a disadvantageously large proportion of the space available in this area only to a limited extent.
  • the production of correspondingly smaller heating cartridges of sufficient power is difficult and expensive.
  • Resistance heating wires have also already been used as heat-donating components, the heating wire being placed around the cylinder housing, for example. This makes the lock assembly difficult and expensive, among other things.
  • PTC resistors have also already been used, but their space requirement is large for the required heating power while observing the necessary fatigue strength.
  • the invention has for its object to design the door cylinder of the type mentioned so that only a small space requirement is required at high heating power, while the heating element should have good thermal resistance and as a commercially available component for a low price Available.
  • a transistor is provided as the heating element. It is a commercially available power transistor, at the PNP (NPN) junctions of which power drops, which heats up the transistor.
  • the heating power is sufficient to free the lock cylinder from icing within a short time.
  • a resistor is connected between the base and the emitter of the transistor. The heating power of the transistor results from the voltage that is present at the emitter and collector and the current that flows across the emitter-collector path.
  • a heat-dependent resistor in the circuit, which is preferably arranged in the immediate vicinity of the cylinder housing of the locking cylinder.
  • the heating output can thus be adapted to the respective temperature of the locking cylinder.
  • the emitter-collector current is dependent on the current with which the base of the transistor is driven. Because only a small amount of electricity to control the base, it is possible to optimally adapt the heating transistor to the required conditions with the help of electronic components. As a result of the immediate proximity of the heat-dependent resistance to the cylinder housing, very direct temperature control can be achieved and the least possible energy loss can be achieved.
  • the heating element is expediently designed as a plug-in component.
  • the cylinder housing advantageously has an undercut groove in which the transistor can be inserted.
  • a metallic base plate embedded in the transistor preferably protrudes on both sides beyond the transistor body. The protruding edges of the base plate are taken up by the groove of the cylinder housing. So that the base plate lies directly on the cylinder housing, so that a large area good heat transfer is guaranteed.
  • the switch is preferably a non-contact switch, which can be designed as a reed contact switch, for example.
  • the circuit can also comprise a timing relay, by means of which the circuit can be kept closed for a predetermined period of time. It is enough to press the handle of the door handle once to initiate and maintain the heating process until defrosting is complete.
  • the door handle is provided with the reference number 10 in its entirety.
  • the handle 11 is substantially U-shaped. It carries at the front end a fastening tab 12 and at the rear end a fastening tab 13 for permanent fixation of the handle 11 on the motor vehicle door, not shown.
  • a handle button 14 for actuating the lockable cylinder 15 is held pivotably about a pivot pin 16.
  • the cylinder housing 22 carries an undercut Tene groove 23.
  • a metallic base plate 21 is embedded in the transistor 17, which projects on both sides beyond the transistor body.
  • the base plate 21 of the transistor 17 is inserted into the groove 23 of the cylinder housing 23, so that there is a structural unit.
  • the entire surface of the base plate 11 lies against the cylinder housing 22, so that the heating power of the transistor 17 can be delivered to the locking cylinder with the least loss.
  • Fig. 3 shows the circuit diagram of the heating device.
  • the voltage of the car battery 25 is applied between the emitter and the collector of the transistor 17.
  • a resistor 18 is connected between the emitter and the base of transistor 17.
  • the heat-dependent resistor 19 is located in the immediate vicinity of the transistor 17 or the cylinder housing 22.
  • a contactless switch 21 is provided for closing the circuit.
  • the embodiment shown is a reed contact switch which can be actuated by means of a magnet 20.
  • the magnet 20 is located on the handle button 14 of the door handle 10. When the handle button 14 is actuated, the magnet 20 approaches it Switch 21, whereby the switch contact is triggered.
  • the two extreme positions are shown in FIG. 1, the switch position being indicated in dashed lines.
  • the function of the door cylinder heating will be explained below. If the cylinder is iced over, the door lock cannot be unlocked. The lock actuation, i.e. the handle button 14 of the door handle 10 is still pivotable. However, the door does not open because the safe state is still present.
  • the magnet 20 moves towards the reed contact 21 and switches on the current.
  • the heating transistor 17 becomes conductive and heats up the cylinder housing 22 and the temperature-dependent resistor 18.
  • the resistor 18 changes its resistance so that the base current becomes smaller and the emitter-collector current also depends on it.
  • the heating power of transistor 17 decreases and the temperature adjusts itself to a desired value in accordance with the selected temperature-dependent resistance. This value is based on the required heating output e.g. at an object temperature of around 60 ° C.
  • the device is designed without a time relay, the heating remains switched on as long as the handle button 14 of the door handle 10 is held in the pressed state.
  • the device can comprise a time relay, so that only a one-off Actuation - or for safety reasons a double actuation within a predetermined period of time - the handle button 14 is required to initiate the heating process, which is maintained according to the switching time of the relay over a predetermined period.
  • the entire heating system comprises only a few components, which are completely combined to form a heating module. It is cast into a watertight unit 26 or is accommodated in a correspondingly sealed plastic housing and can be prefabricated ready for plug-in.
  • a plug-in coupling 28 is provided at the end of a connecting cable 27.
  • the invention can also be implemented unchanged on other types of handles, for example on handles or also on folding handles.
  • the switch or the magnet of the reed switch is directly or directly assigned to the movable opening element.
