Abstract

PURPOSE: To ensure functions even under extreme outside conditions such as a temperature condition by providing at least one switch which can be operated magnetically. CONSTITUTION: When an operation magnet 3 is brought close to a reed relay 2 that is installed on the back side of a glass board and the distance between the operation magnet 3 and the reed relay 2 reaches a fixed set distance, a contact operation becomes effective. That is, two contacts 7, 8 capable of being magnetized are closed as long as the operation magnet 3 is maintained at the position. As a result, since a heating resistance 5 is supplied with a current by a storage battery 13, a base material 6 which conducts heat and a lock cylinder portion 14 are heated adequately, and defrosting or defrosting of a door lock are performed. Therefore, functions are ensured even under extreme outside conditions such as a temperature condition.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electrical system for one or more electrically actuatable or operable or current consuming components or units in a vehicle, such as an automobile. The present invention relates to a switching device for switching (turning on/off) a current circuit.

PRIOR ART In a device for, for example, a door lock of a vehicle or a house, in which the frozen lock cylinder is melted by a heating element, a key is used for the purpose of supplying current to the heating element and thereby injecting the heating current. It is known that by inserting a lock into the locking barrel of the lock, a separate switch provided for this purpose is actuated.

However, such known switching devices for switching on the heating current are susceptible to disturbances, e.g. under extreme environmental conditions, for example when the lock is completely frozen, actuating the switch using the key is no longer possible. It has the disadvantage that it is no longer completely possible.

OBJECT OF THE INVENTION It is therefore an object of the invention to provide an improved switching device, with which a contactless and controllable actuating connection of a current circuit is possible, in which case The object of the present invention is to provide a switching device whose functionality is guaranteed even under extreme external conditions, such as temperature conditions.

Means for Solving the Problem According to the present invention, this problem is solved by combining the configurations described in the characteristic part of claim 1 based on the switching device described in the generic concept of claim 1. be done.

Advantageous embodiments of the invention are described in the subclaims.

Advantages of the invention In switching devices of the type described, manually actuatable switches, for example actuatable by means of a key, are completely abandoned, and instead at least one magnetically actuatable switch is provided, which As an example,
The central idea of the invention is that the switch is mounted, for example, directly on the back side of the glass pane of a vehicle door, so that it can be started and stopped from the outside by means of an associated actuating magnet.

The operation of a magnetic switch of this type is virtually independent of environmental influences, so that the operation of the switch can be realized under practically all conceivable conditions.

Advantageously, the switching device according to the invention has at least one switch in the form of a reed relay.

Further embodiments of the invention are provided, for example, when a plurality of elements or units are used, in which the current circuit can be turned on and off when necessary, and which can be turned on and off, for example, separately and independently of each other. The switching device is preferably constructed in such a way that it has a corresponding number of mutually modified switches, the switches being arranged together approximately in the form of a matrix and having assigned actuations. Each can be actuated individually by magnets. In such a case, too, a matrix with individually magnetically actuatable switches can be arranged visible on the back side of the glass pane of a vehicle, for example a car, so that each desired switch can be directly connected to the vehicle. Guaranteed to operate from outside.

In order to prevent an unauthorized third party from triggering the switch operation using any suitable permanent magnet,
According to a further embodiment of the invention, a coded mutual correspondence is provided between each individual switch on the matrix and each correspondingly assigned actuating magnet. Therefore, only a person who knows the respective coded correspondence can magnetically actuate the desired switch in each case and thereby supply current to the desired component or unit in each case. This can be done, inter alia, by means of a switching device constructed according to the invention, for example for door lock de-icing devices, central locking devices, vehicle auxiliary heaters, anti-theft or vehicle This is very important when starting and stopping different units in a vehicle, such as an anti-pry alarm system, a de-icing system for a trunk lid lock, a car radio anti-theft system, etc., independently of each other. .

Furthermore, within the scope of the invention it is also provided that the switching device according to the invention is used for activating a coded trunk lid lock or for activating a coded glove conversion lock. There are also some configurations.

In the last mentioned case, the locks on the luggage compartment lid or the glove compartment locks can be individually and magnetically actuated in each case, such that they can only be actuated by one encoding method with the aid of an assigned magnet. An integrated switch means that the luggage compartment lid lock or the glove compartment can only be opened using the correct magnet.

As a result, if a car is parked, for example, in a guarded parking lot or, for example, in a hotel's underground parking lot, the parking lot guard will be able to lock the key to his vehicle without having to handle the luggage in the luggage compartment. The following description of an advantageous embodiment, based on the accompanying drawings, which can be handed over to the parking lot warden or other appropriate person without any problems, serves as a detailed explanation of the invention and its detailed features and advantages, in which: In the drawings, like reference numbers consistently represent like parts and parts.

DESCRIPTION OF THE EMBODIMENTS As is clear from FIG. 1, a switching device 1 for switching on a current circuit for an electric de-icing device for a doorway ivy by non-contact control basically has a reed relay 2.
In this case, two movable magnetizable contacts 7 are provided in the glass capillary 9, as is already known per se in the case of reed relays.
and 8 are welded.

The connecting line 10 is led from the first contact 7 to one terminal of the heating resistor 5, whereas the line 11 is led from the other terminal of said heating resistor to the accumulator 13. A further line 12 is provided from this accumulator 13 to the second contact 8 of the reed relay 2 . A heating resistor 5, which can for example be a resistor with a positive temperature coefficient, is embedded in a support 6 which has good thermal conductivity but is electrically non-conductive, and which supports a car door lock. It is in direct contact with the side surface of the locking cylindrical portion 14. For example, in Figure 2,
A vehicle body 15 of a motor vehicle with a vehicle door is shown in a partial side view, the vehicle door having a glass pane 16 and a door handle 17 with a door lock to which the locking cylinder 14 belongs, as is known in the art. and has. A reed relay 2 is arranged directly on the inner surface of the glass pane 16 of the vehicle door in the upper region of the door lock. The switching device for the door lock de-icing device furthermore has a device, as shown in FIG. 1, for example in the form of a permanent magnet, which is individually assigned to the reed relay 2 and which triggers the switching process in a known manner. An actuating magnet 3 is included for this purpose. Advantageously, this actuating magnet 3 can also be mounted on the key head of the vehicle door or, although not shown in detail in the drawing, on the key holder of the vehicle door key. .

When the user wants to start the doorway de-icing device, he brings the actuating magnet 3 close to the reed relay 2 provided on the back side of the glass plate 16, thereby reducing the distance between the actuating magnet 3 and the reed relay 2. When a predetermined set distance is reached, contact operation becomes effective, ie the two magnetizable contacts 7 and 8 are closed as long as the actuating magnet 3 is held in its position.

As a result, the heating resistance 5 of the door lock deicing device is
3, the heat-conducting support 6 is accordingly heated, which ultimately leads to a corresponding heating of the locking cylinder 14, so that it is possible to de-ice the locking cylinder or remove door ivy. De-icing is carried out.

According to experimental values, this type of deicing process takes about 30 seconds.
The heating resistor 5 must then be supplied with current from the current circuit assigned to it, as already explained above with reference to FIG. Then actuating magnet 3
can be moved away from lead relay 2 again, so
Both magnetizable and resilient contacts 7 of a reed relay
and 8 are again pulled apart from each other, thereby opening the reed relay and interrupting the current circuit again.

Furthermore, FIG. 3 shows an embodiment of a switching device according to the invention, in which case a type of switch board 1
A predetermined number of switches 2 are arranged in the form of a matrix on 8, each switch being provided with a reed relay 2 as shown in FIG. In practice, these reed relays 2 are preferably mutually modified in such a way that the individual reed relays 2 can be operated separately, with a correspondingly assigned actuating magnet 3 However, this is not shown in FIG. 3 for convenience.

This kind of switch matrix or switch board 18 is
For example, it can likewise be mounted directly on the back side of the glass pane of a motor vehicle, so that in this case a corresponding number of different parts or units in the motor vehicle can be turned on and off individually by means of an actuating magnet assigned to each one. In this case, it is advantageous to provide a coded correlation between the individual reed relays 2 and the individual actuating magnets on the matrix 18.

Magnetically operable switching devices of this type are protected against tampering by unauthorized third parties.

By means of the switching device shown in FIG. 3, the user can, by means of the respective actuating magnet, control a current circuit for, by way of example, a door lock de-icing device 19, an alarm device 20 or, for example, a car radio anti-theft device 21. can be selectively dosed in a controllable manner without contact.

Of course, by using the switch matrix 18 according to FIG. 3, further different units can be activated or driven by switching in the corresponding current circuits, with the door lock de-icing As already explained in detail above with reference to FIG. 1 in connection with the device 4, each individually actuated magnet 3 is used.

Additionally, the switching device according to the invention can be installed very generally in vehicle door locks and house door locks, for example, in addition to car door lock de-icing devices.

Effects of the Invention The invention makes it possible to switch on electrical current circuits in a contactless manner, in such a way that the functionality of the switching device is guaranteed even under extreme external conditions, e.g. temperature conditions. A switching device is provided.
