Description

The invention relates to an air supply device for a motor vehicle body of a motor vehicle according to the preamble of claim 1. Air supply devices for influencing the airflow around and/or through the vehicle body are known. For example, air supply devices are used in the front area of the vehicle body, where they create a defined airflow, which, for instance, serves to supply air to a cooling unit. The air supply device has a pivotable closing element that can open or close a body opening in the vehicle body, thus making the opening in the front area adjustable. The body opening is usually curved, so the closing element for completely closing the opening is also curved. From the disclosure document DE 10 2019 112 440 A1 An air supply device with a closing element divided into several closing element components adjustable between a closed position and an open position is shown, wherein the closing element components form a closed plane in the closed position, and wherein the closing element components are translationally adjustable between the closed position and the open position. The patent specification FR 3 038 550 B1 Disclosing an air supply device with a closing element which is moved translationally and rotationally when adjusted between a closed position and an open position. The patent specification FR 3 048 646 B1 A locking element for a body opening can be removed from a front element of a motor vehicle, whereby the locking element is swung upwards using a cam kinematic system. From the disclosure document KR 10 2021 0 122 537 A A closing element for a body opening on the front element of a motor vehicle is known, wherein the closing element is flush with a motor vehicle body that limits the body opening in a closed position and is arranged at 90° to the closed position in an open position. The disclosure document DE 10 2004 056 328 A1 and the patent specification DE 37 31 980 C1 Each discloses a closing element for a body opening on the front element of a motor vehicle, with a guide device for changing the shape of the closing element from a curved shape in the closed position to a flat shape in the open position, wherein the closing element is designed to perform a positioning movement from the closed position to the open position, which has a translational and a rotational movement. The object of the present invention is to provide an improved air supply device for a motor vehicle body. This problem is solved according to the invention by means of an air supply device for a motor vehicle body with the features of claim 1. Advantageous embodiments with expedient and non-trivial further developments of the invention are specified in the respective dependent claims. An air supply device according to the invention for a motor vehicle body has a locking system with a locking element which is connected to a guide device of the air supply device for guiding the locking element by means of movement elements, wherein the locking element can be moved into a closed position and into an open position for closing or opening a body opening of the motor vehicle body. The locking element has at least two element parts. The guide device has a positive guide for changing the shape of the locking element from a curved shape in the closed position to a flat shape in the open position, wherein the locking element is designed to perform a positioning movement from the closed position to the open position, which includes a translational and a rotational movement. According to the invention, adjacent element parts are movably connected to one another, wherein a relative movement of the element parts to each other is formed transverse to a positional movement of the locking element. In other words, the locking element, with the aid of the guide device, is designed to change shape from a curved to a flat shape and vice versa. The advantage is that the curved shape, especially a highly curved one, can adapt to the vehicle body, particularly forming a flush seal when the body opening is closed, and that the locking element can be fully, due to Its flat shape, achieved with the aid of the guide device, can be removed from the body opening, leaving the opening completely uncovered and thus allowing improved airflow into the opening. The closing element is divided into component parts, allowing each component to be assigned its own rail for secure shape change, and enabling the closing element to be manufactured from an inflexible and rigid material. To form a closed closing element, the adjacent component parts are movably connected, allowing them to move relative to each other. This relative movement of the component parts is transverse, and in particular orthogonal, to any positioning movement of the closing element. With the help of the translational movement, the locking element is moved from the closed position and thus out of the body opening, and with the help of the rotational movement it is pivoted so that it can
