Description

The invention relates to an electrical operating unit with a shaft for receiving an emergency key, wherein the emergency key stored in the control unit and can be pulled out as needed. Such control units are known, for example, as a remote key or radio remote control for the central locking of a vehicle.

In addition to the embodiments with a separate, removable emergency key (cf., for example. DE 19943498 A1 ) are also embodiments with an attached to the control unit emergency key (see, eg. DE 4238042 A1 ), in which the emergency key is pushed or swiveled into the use position.

The DE 102004026164 A1 shows an embodiment in which the emergency key is located in the key housing in a slot through which it is performed when putting in and out. When pulling out the emergency key is pulled to a use position to stop. To prevent it from being pushed back into the shaft during use, this must be prevented. This is at the DE 102004026164 A1 provided on the emergency key, a button which cooperates with corresponding retaining apertures and pushed by pressing the respective key from the retaining hole and the emergency key can be moved. Such a button is a design effort.

Such electrical control units (cf., for example. DE 42 26 579 A1 ) have for electrical power supply usually a battery, which is arranged interchangeably in a battery compartment. However, the battery compartment and the emergency key slot increase the required installation space. For moisture protection, the battery compartment must be closed by a removable battery compartment cover. However, there is the risk of loss of the battery compartment lid.

The object of the invention is therefore to introduce an operating unit with an emergency key, in which a simple way of securing the emergency key in use against being pushed back into the shaft. In addition, an embodiment of an operating unit with an emergency key slot and a battery compartment is to be presented, in which a space-saving layout is ensured, and a provided for a battery compartment battery cover is particularly easy to secure against losing.

This object is solved by the features of the independent claim. Advantageous developments can be found in the dependent claims.

The pushing back of the key is inventively prevented by the battery compartment cover or a mechanically connected locking element by automatically jumping into a second, the emergency key locking position or manually moved. The battery compartment cover is usually movable for changing the battery, for example, designed to be rotatable. This movement of the battery compartment cover is used to move the battery compartment cover or a locking element configured thereon between the locking and unlocking position. The locking position of the battery compartment cover preferably corresponds to the locking position of the emergency key.

Preferably, a jumping movement of the battery compartment cover is provided, which causes the locked position of the battery compartment cover and the emergency key. This can ideally be done by the battery contact, which is, for example, under the battery and advantageously has spring property. The battery in turn is pushed through the battery compartment cover onto the battery contact.

The shaft for the emergency key passes through the battery compartment. In this case, the emergency key acts as a captive for the battery compartment cover, which is considered to be an independent inventive aspect of this particularly preferred embodiment.

To be pushed back into the housing after use, the battery cover must be pressed back into the starting position or rotated.

The invention will now be explained in more detail by means of exemplary embodiments with the aid of the figures.
