Door handle for a vehicle door
A door handle for a vehicle door of a motor vehicle includes a carrier plate, a handle cavity, and an extendable handle part. At least one lighting device arranged in/on the carrier plate or on the handle part is provided with at least one lighting element and/or a light guide element. The handle part is adjustable between a retracted non-use position, a partially extended intermediate position, and an extended use position. The at least one lighting element and/or the at least one light guide element, when the handle part is in its partially extended intermediate position, at least partially illuminates a gap present between the handle part and the handle cavity. When the handle part is extended, at least one lighting element and/or the at least one light guide element illuminates at least parts of the handle part, of the handle cavity, and/or of an area surrounding the handle part.
1. A door handle for a vehicle door of a motor vehicle, the door handle comprising:
a carrier plate;
a handle cavity;
an extendable handle part; and
at least one lighting device arranged in or on the carrier plate or on the handle part, wherein the at least one lighting device includes at least one lighting element or at least one light guide element,
wherein the handle part is adjustable between a retracted non-use position, a partially extended intermediate position, and an extended use position,
wherein the at least one lighting element or the at least one light guide element, when the handle part is in the partially extended intermediate position, at least partially illuminates a gap between the extendible handle part and the handle cavity, and
wherein, when the extendible handle part is in the extended use position, illuminates at least parts of the extendible handle part, the handle cavity, or an area surrounding the extendible handle part.
2. The door handle of claim 1 , wherein the gap has a gap width between 3 mm and 5 mm when the extendible handle part is in the partially extended intermediate position.
3. The door handle of claim 2 , wherein the gap has a gap width between 5 mm and 10 mm when the extended handle part is in the extended use position.
4. The door handle of claim 1 , wherein the extendible handle part includes at least one edge lighting element or at least one edge light guide element, and when the extendible handle part is in the extended use position, the at least one edge lighting element or the at least one edge light guide element produces an illumination that at least partially surrounds the extendible handle part as a light edge.
5. The door handle of claim 1 , further comprising:
a control device, wherein the control is configured to
set a light intensity of the at least one lighting element depending on a position of the extendible handle part so that the light intensity is increased or reduced based on the position of the extendible handle part, or
adjust a color of light emitted by the at least one lighting element based on the position of the extendible handle part.
6. The door handle of claim 1 , wherein the extendible the handle part is translationally or pivotally adjustable between the extended use position and the retracted non-use position.
7. A motor vehicle, comprising:
a vehicle door;
a door lock;
an electronic key configured to lock and unlock the door lock; and
a door handle, which comprises
a carrier plate;
a handle cavity;
an extendable handle part; and
at least one lighting device arranged in or on the carrier plate or on the handle part, wherein the at least one lighting device includes at least one lighting element or at least one light guide element,
wherein the handle part is adjustable between a retracted non-use position, a partially extended intermediate position, and an extended use position,
wherein the at least one lighting element or the at least one light guide element, when the handle part is in the partially extended intermediate position, at least partially illuminates a gap between the extendible handle part and the handle cavity, and
wherein, when the extendible handle part is in the extended use position, illuminates at least parts of the extendible handle part, the handle cavity, or an area surrounding the extendible handle part.
8. A method for operating a door handle on a motor vehicle, the method comprising:
detecting that an authorized user with an electronic key approaches the motor vehicle;
extending, responsive to the detection, a handle part of the door handle from a retracted non-use position into a partially extended intermediate position,
at least partially illuminating, responsive to the detection, a gap between the handle part and a handle cavity of the door handle by at least one lighting element or at least one light guide element that is part of the door handle;
determining that the authorized user opens a door lock of the motor vehicle with the electronic key;
transferring, responsive to the determination, the handle part from the partially extended intermediate position into an extended use position;
illuminating, responsive to the determination and using the at least one lighting element or the at least one light guide element, at least parts of the handle part, the handle cavity or of an area surrounding the handle part.
9. The method of claim 8 , wherein a light intensity of the at least one lighting element is set depending on a position of the handle part so that the light intensity increases or reduces with increasing state of extension of the handle part.
10. The method of claim 8 , wherein a color of light emitting by the at least one lighting element is adjusted as a function of a position of the handle part.
