Description

The invention relates to a door handle arrangement of a vehicle door and a vehicle with such a door handle arrangement.

The DE 20 2014 010 524 U1 relates to a door handle arrangement for a motor vehicle.

The object of the invention is to provide an aerodynamically favorable, user-friendly and at the same time simply constructed door handle arrangement.

The invention results from the features of the independent claims. Advantageous further developments and refinements are the subject of the dependent claims.

A first aspect of the invention relates to a door handle arrangement of a vehicle door, wherein a handle of the door handle arrangement is connected at a first end of the handle to a first holding arm mounted in the vehicle door and at a second end of the handle is connected to a second holding arm mounted in the vehicle door, wherein the second holding arm is connected to a locking mechanism of the vehicle door and is displaceable by an imaginary local tangential plane lying against the vehicle door, so that the handle can be moved between a latching position and an actuating position, the first holding arm being a spring element for generating a restoring force against rotation and / or moving the handle in a direction directed away from the tangential plane outward from the vehicle door, the handle being at least partially recessed in the locked position in the vehicle door and in the actuating position is at least at its second end spaced from the vehicle door to form a grip space for inserting the fingers between the grip piece and the vehicle door, and the closing mechanism being opened by actuating the grip piece in the actuating position.

The vehicle door is in particular a door of a vehicle such as a car, truck, bus, rail vehicle, watercraft (for example a ship), underwater vehicle, or an aircraft.
The locking mechanism is preferably connected to the lock of the vehicle via a Bowden cable in order to bring about a movement in the locking mechanism by actuating the handle in the actuating position, which in turn brings about a mechanical opening of the lock.

The handle is actuated in the actuating position in particular after the handle has been moved from the latching position into the actuating position. The movement of the handle from the locking position into the actuating position is preferably carried out with a corresponding signal for opening a locking of the vehicle by a key for the vehicle.

The first holding arm is preferably mounted immovably in relation to the vehicle door of the vehicle.

It is an advantageous effect of the invention that the door handle arrangement of the vehicle door causes only a minimal air resistance force and at the same time can be opened ergonomically and is inexpensive to manufacture due to the small number of components.

According to an advantageous embodiment, the second holding arm can be moved through the tangential plane by means of an actuator-driven adjusting element.

The second holding arm can preferably be moved through the tangential plane by means of an electrically driven adjusting element.

The expression “movable through the tangential plane” means a movement which has at least one kinematic component perpendicular to the tangential plane, the direction of movement coming from the vehicle door being directed outward out of the vehicle door in the case of the movement of the handle from the latching position into the Actuating position and in the opposite direction in the case of movement of the handle from the actuating position to the locking position.

Furthermore, during a movement “through the tangential plane”, the tangential plane lying on the surface of the vehicle door is pierced.

According to a further advantageous embodiment, the first holding arm is displaceably supported through the tangential plane, so that the grip piece can be moved between a latching position and an actuating position in a position parallel to the tangential plane and in a direction perpendicular to the tangential plane. There is no rotational movement of the handle piece relative to the vehicle door.

According to a further advantageous embodiment, the first holding arm is fixed to the vehicle door and the handle is rotatably connected to the first holding arm by a mechanical joint at its first end, and the spring element generates a spring torque against rotation about the mechanical joint.

The spring torque against twisting around the mechanical joint is preferably oriented such that twisting the handle, in particular twisting the second end of the handle, around the mechanical joint as a pole leads from the detent position into the actuating position to an increasing restoring moment by the spring element.

According to a further advantageous embodiment, the first holding arm is fixed to the vehicle door, the spring element being an elastic, flexible zone at the first end of the handle and / or on the first holding arm at the connection point of the first end of the handle with the first holding arm, so that the handle is opposite the first holding arm is rotatable against a spring moment.

This spring torque against twisting around the flexible zone is preferably oriented such that twisting the handle, in particular twisting the second end of the handle, leads from the latching position into the actuating position to an increasing restoring moment through the flexible zone. The elastic, flexible zone advantageously combines the function of the mechanical joint and the spring element in one and the same component, in particular as a predefined zone in the handle and / or in the first holding arm.

According to a further advantageous embodiment, the second holding arm has a flexible zone at the connection point to the second end of the handle.

If the handle is rotated relative to the vehicle door, an angular compensation is necessary to geometrically compensate for the translatory movement of the second holding arm resulting from the vehicle door, in particular in the case of a straight second holding arm. This angle compensation is advantageously realized by an elastically deformable, flexible zone in the second holding arm and / or at the second end of the handle.
According to a further advantageous embodiment, the second holding arm has a curved course in a longitudinal direction of the second holding arm, the vehicle door having a guide with a curved course in the longitudinal direction of the guide that matches the curved course of the second holding arm.

According to this embodiment, the necessary geometric compensation described above is made possible by a circular guide and a circular shape of the second holding arm. Regardless of whether the grip piece rotates around a mechanical joint or around a flexible zone around the connection point between the first end of the grip piece and the first holding arm, the second end of the grip piece executes at least approximately an arcuate path with respect to the vehicle door. If the second holding arm is designed in the form of a segment of an arc of a circle, it can follow the arc-shaped path when the handle is moved between the detent position and the actuation position without collision.

According to a further advantageous embodiment, the second holding arm has a restoring spring for generating a restoring force against displacement of the second holding arm in a direction directed away from the vehicle door from the tangential plane.

According to a further advantageous embodiment, the grip piece borders on the tangential plane in the latching position.

In particular, the handle is then at least partially sunk into the vehicle door in the locked position and the handle borders in the locked position on the tangential plane. This means in particular that the grip piece in the latching position is adjacent to the tangential plane from a half space on the vehicle door side, which is defined by the tangential plane, to the tangential plane. In other words, the handle is then recessed so deeply in the vehicle door that the handle does not protrude beyond the tangential plane in its latching position and does not protrude from the tangential plane. This advantageously reduces the aerodynamic drag of the vehicle to a minimum.

Another aspect of the invention relates to a vehicle with at least one door handle arrangement as described above and below.

Further advantages, features and details result from the following description, in which - if necessary with reference to the drawing - at least one exemplary embodiment is described in detail. Identical, similar and / or functionally identical parts are provided with the same reference symbols.
