DE19930861A1 - Vehicle door handle has pivot lever on actuating lever extending into interior of vehicle door to actuate switch and functional element when actuating element pivoted into switching position - Google Patents

Abstract

The door handle has an actuating element (3) that can be pivoted in a first direction from an initial position (0) into an opening position (I) against the force of a first spring (5) and in the opposite direction against the force of a second spring (6) from the initial position to a switching position (II). A first pivot lever (8) on the actuating lever reaches into the interior of the vehicle door to actuate a second switch (12) and a functional element (13) when the actuating element is pivoted into the switching position.

Description

The invention relates to a door handle for a vehicle door according to the features of the preamble of claim 1.

Door handles for vehicle doors usually include one each Actuator designed as a flap or handle ment with at least one protruding into the door interior Swivel lever is connected. This pivot lever then acts either mechanically via a linkage or a Bowden cable or via an electrical switch with a downstream electronic control device on the door lock.

DE 196 17 038 A1 describes a motor vehicle with a electronic monitoring device for identification of persons authorized to open (passive entry system) known. In this case, when approaching the vehicle via a contactlessly arranged on the vehicle door Sensor generates a signal, which in the vehicle via a electronic control device activates a transmitter. This sends corresponding signals and via an antenna  automatically queries an identity giver who is concerned with the Person approaching the vehicle. Are the dates correct of the identity provider with the corresponding stored Data of the control device, so the respective Door lock unlocked and can then z. B. about a sensor or micro arranged on the outside door handle switches are opened.

As far as the applicant is aware, the electronic monitoring device usually by the authorized user This activates the person after leaving the vehicle ("Armed") that one on the bottom of the handle flap or the handle arranged switch operated becomes.

The arrangement of such an additional switch in the loading The outside door handle is rich with a relatively complex Attachment of the switch to the actuator verbun the, as it must be protected against the ingress of moisture got to. The switch also requires additional space in the Area of the grip area.

The present application is based on the task To specify door handle of the type mentioned, with the in addition to opening the lock in a simple way white tere functional elements are actuated.

This object is achieved by the features of characterizing part of claim 1 solved. Further, esp disclose advantageous embodiments of the invention the subclaims.

The invention is essentially based on the idea that the actuating element of the door handle against the pressure  corresponding springs from a starting position two sides of the opposite direction are pivoted is arranged. The swiveling movement into one Direction of the actuator in a conventional manner in the opening position swivels and leads to a corresponding appropriate actuation of the door lock. Through the swivel movement supply of the actuator in the opposite direction tion, the actuator is in a switch position pivoted at a in the interior of the vehicle door reaching first lever actuates a switch. This then in turn activates corresponding functional elements (e.g. the monitoring device of the passive entry system).

Such a door handle has the advantage, among other things, that in the area of the handle space no additional space for a switch is needed. It is also an additional one Sealing the inside of the vehicle door Switch against moisture is not necessary because of the Interior of the vehicle door in the area of the door handle anyway is sealed against moisture coming from outside.

Further details and advantages of the invention emerge from the following embodiment explained with reference to a figure example.

The figure schematically shows a vehicle door 1 with an outer door handle 2 designed as a flap handle. The outside door handle 2 comprises a handle flap 3 , which from a starting position labeled "0" about an axis 4 both upwards into an open position I and downwards into a switch position II against the pressure of a first or second spring 5 or dashed line indicated by dashed lines 6 is pivotable. On the handle flap 3 in the interior 7 of the vehicle door 1 projecting pivot lever 8 is attached. When the opening position I is reached, this actuates a first microswitch 9 , which activates the electric motor (not shown) of an electric door lock 11 via an electronic control device 10 and thus opens the vehicle door 1 .

However, if the handle flap 3 is pivoted downward into the switching position II, the pivoting lever 8 actuates a second microswitch 12 , which activates a known electronic monitoring device 13 for identifying the persons authorized to open the vehicle door 1 ("armed" switch ).

The invention is of course not limited to the embodiment described above. Thus, for example, an apron lighting can also be switched on with the second microswitch 12 instead of "arming" a monitoring device 13 for identifying people approaching the vehicle. In this case, the lighting of the vehicle is switched on for a predetermined period of time when the handle flap of the door handle is switched to the switching position II. It is also conceivable to switch on a warning system of the vehicle by means of the handle flap 3 etc.

Furthermore, the pivot lever 8 does not directly actuate the corresponding microscale ter, but it can also be arranged on the pivot lever, for example, additional switching cams, which then act on the switch.

In addition - depending on the specific spatial conditions and the functional elements to be switched - with the handle  fold several swiveling levers instead of just one bel connected, each on one or more switches Act.

Finally, the control device 10 and the monitoring device 13 can also be combined in a single electronic unit which is arranged inside or outside the vehicle door.
