Switching device for instrument panels and dashboards, in particular for setting and switching the air conditioning in car interiors

SWITCHING DEVICE PUR INSTRUMENT OR AHMATURE BOARDS, IN PARTICULAR FOR SETTING TFD SWITCHING OF AIR CONDITIONING IN CAR INTERIORS.

The present invention relates to a switching device which is attached to instrument panels or dashboards can be attached and especially for setting and switching the air conditioning in car interiors suitable is.

It is known that currently in automobiles a ICLxmatisierungsanlage is provided, which is more or less complicated depending on the type of motor vehicle itself is built. This air conditioning system is essentially used for the interior of the car on a for to keep the passengers at a comfortable temperature, to renew the air in such a way that it always remains fresh,

.8th·

and to always keep the window panes completely transparent.

These functions are obviously subject to special circuits using push buttons, switches and the like, which are arranged in various ways on the dashboard and / or the instrument panel.

The object of the present invention is to provide a switching device that is in a compact Construction includes all of the above switch-on devices.

Within the scope of the above-mentioned object, a particular object of the present invention is to provide a switching device for setting and switching the air conditioning in motor vehicles that Has instruments that are suitable to give the user a complete overview of the operating status to give to the plant.

Another object of the present invention is to provide a switching device for the circuit and setting the air conditioning in motor vehicles, which is able to function independently and while inside the vehicle a predetermined, maintain the temperature selected in advance by the user.

The above-mentioned task as well as the goals indicated above and other goals, which may subsequently be will appear more clearly, will be shown with an on instrument panels or dashboards of motor vehicles.

testify attachable switching device for switching the air conditioning yellow or achieved, according to the invention is characterized in that it has snap fasteners of the normal type and toggle snap fasteners, which are suitable for special, to act on a printed circuit led tracks in such a way that impulses to a central processing unit (or a microprocessor unit (MPU)) capable of interacting with a sensor, the temperature - the value of which can be predetermined and can be determined via a display - in the interior room by acting on air currents flowing out of conventional ventilation nozzles, whereby furthermore, the flow rate, which is displayed via a corresponding barographic device, can be set is and where further push buttons to effect the air supply even with different types of flow to one or more of the aforementioned nozzles are provided, in particular the aforementioned push buttons are provided with appropriately lit ideograms and equipped with indicator lights that are suitable are to indicate the activation of the special punctures controlled by the same push buttons.

Further features and advantages of the invention, Switching device for adjustment that can be attached to instrument panels or dashboards of motor vehicles and switching of the air conditioning can be done with the help of the the following description of a preferred embodiment of the device itself can be better understood, purely for example in the various figures

• / O ·

of the accompanying drawings, in which:

in Fig. 1 this device is shown in an end view is;

in Fig. 2 is a horizontal section of the lower part of the the same device is partially shown according to two different parallel planes;

in Fig. 3 a horizontal section of the present device according to two successive intermediate levels is illustrated.

With particular reference to the reference numerals of the various figures of the accompanying drawings the switching device for switching the air conditioning in the interior of motor vehicles according to the invention a central processing unit (not shown) which is able to process information from a rigid printed circuit (1) whose conductor tracks are interconnected by a large number of push buttons can be connected, and supplied by a temperature sensor (2), select, coordinate and process.

More precisely, the device is installed in a housing 3, on the end wall of which there are three parallel strips can be seen, which are denoted by 4, 4 'and 4 ". In the middle strip 4' there is a first toggle button 5, a first push button 6 normal type and a second toggle push button 7 stored.

In particular, the first toggle push button allows through Acting on an electric door mi I; mohroron oonchwin-

to change the total amount of air supplied to the various open air vents, whereby this amount of air can be determined by the user via a barograph 8.

The second toggle button 7, on the other hand, enables the temperature to be set that is maintained in the motor vehicle should be, between a lower and a higher value, the value on a display 9 is displayed and both in Celsius degrees and in Pahrenheitgrad by acting on a corresponding Toggle switch 10 can be expressed.

The push button 6 in turn enables the temperature set on the aforementioned display to be stored, so that the setting of the same depends on the possible deviations caused by the probe 2 can be determined automatically.

In the lower strip 4 ″ of the end wall a series of push buttons 11 of normal type is mounted, one of which controls the operation of the electric fan mentioned, while the others are able to supply the air against one or more ventilation nozzles arranged inside the motor vehicle, possibly also with one Control differentiation of the amount of air supplied to the individual nozzles.

The operating buttons of the mentioned push buttons are made of completely transparent material, preferably methacrylate, so that they can be seen from below corresponding lighting by individual lamps 12, the luminous flux of which easily changes from one key to the other

is transmitted, can receive.

The latter buttons are attached to terminal boards 13, which are also made of methacrylate and which are provided with centering pins 14 which are suitable for being connected to the printed circuit 1 in FIG To get intervention and to commit to this.

The same keys are elastically urged by elastomeric members 15 to equate the suction heads and the cylindrical bumps 16 of conductive material carry coaxially. This cylindrical Elevations are suitable for interruption points in the conductor tracks formed on the printed circuit to connect, these preferably by spiral-shaped sections that run coaxially and in the Area of the ends are separated from each other, are realized.

On the visible surface of the said buttons is also attached a polycarbonate film 17, applied to the corresponding ideograms in the screen printing process that invoke the special functions of the same keys.

The snap fasteners 11 mounted in the lower strip 4 ″ of the front wall are in particular just as many Associated with light-emitting diodes 18, which are suitable for switching on the with the corresponding push button associated function.

From the above statements and from consideration of the various figures and the accompanying drawings

. / 13.

the great expediency and practical applicability clearly show that the switching device according to & 3s of the present invention.
