DE102011018576A1 - Flap i.e. tailgate, for temporarily closing e.g. engine compartment of car, has control device electromechanically driving flap, where flap is opened up to intermediate position when air guiding device is in operational position - Google Patents

Abstract

The flap (2) has an adjustable air guiding device (3) adjustable between a rest position and a driven out operational position, where the flap is pivotable between a closed position (A) and an open position (B). A control device (4) electromechanically drives the flap based on a position of the air guiding device, where the flap is opened up to an intermediate position (C) when the air guiding device is in the operational position. The flap lies lower in the intermediate position than that in the open position around an adjusting path (D) of the air guiding device.

Description

Vehicle flap with adjustable louver, wherein the vehicle door between a closed position and an open position is pivotable and the louver is adjustable between a rest position and an extended operating position.

Such vehicle flaps are used in vehicle construction for temporarily closing body openings, for example a trunk or engine compartment. For aerodynamic reasons, these vehicle doors partly carry an adjustable air deflector (so-called "spoiler"), to increase the contact pressure as needed. However, this usually poses the problem that when the air guide device is extended, it is possible to strike it at relatively low ceilings, which would result in corresponding damage.

Such a vehicle flap with adjustable louver is in the generic EP 2 080 694 A2 disclosed. The louver is arranged on a movable between a closed position and an open position cover of a vehicle and has an air guide, and a storage and adjustment. By means of the storage and adjustment device, the air guide element between a rest position and an extended operating position is adjustable, wherein the air guide is supported with the lid closed on a body structure and / or releasably locked by a locking device. As a result, the lid can only open with the air guide in the rest position, which can lead to significant loss of comfort. If the vehicle is extended, for example, with the spoiler in the operating position, then the driver is the opening of the lid denied until it spends the spoiler again in the rest position.

Object of the present invention is therefore to provide a vehicle flap with adjustable louver, which ensures a safe and yet comfortable operation of the vehicle door, regardless of the position of the louver.

This object is solved by the features of patent claim 1.

A vehicle with a vehicle door according to the invention is claimed in claim 10.

Vehicle flap with adjustable louver, wherein the vehicle door between a closed position and an open position is pivotable and the louver between a rest position and an extended operating position is adjustable and wherein the vehicle door can be opened when in the operating position louver only up to an intermediate position.

By the vehicle door can be pivoted at a befindliches in operating position air deflector only to the intermediate position, which is between the open position and the closed position, the risk of a beating of the louver is banned on low ceilings, without the user has to accept comfort losses. The vehicle flap still opens in the usual way, but not over the full swing range.

In a preferred embodiment, the vehicle door is lower in the intermediate position by an adjustment of the air guide, as in the open position. The intermediate position is preferably determined so that the adjustment of the louver, so the extent to which the louver in the operating position, the vehicle door in the vertical projects, determined and deducted from the open position. In this way, a maximum pivoting range of the vehicle door remains.

In a preferred embodiment, the open position can be variably determined. In particular, the user can manually set a desired open position, which is oriented, for example, to the ceiling height in the domestic garage. The intermediate position is then generated dynamically after deduction of the adjustment of the louver.

In a preferred embodiment, the vehicle door can be operated by external power. In power-operated vehicle doors, there are special advantages, since the vehicle doors here can usually be remotely unlocked and the risk of unintentional striking the louver is correspondingly high. In addition, the external force of the vehicle flap gives a higher torque than in a conventional opening via gas springs.

In a preferred embodiment, the vehicle flap can be driven electromechanically, wherein a control device, depending on the position of the louver, can approach the intermediate position or open position. The electromechanical drive of the vehicle door is currently the most widespread type of drive. Here, an electric motor with rotating output shaft is coupled to a reduction gear, which is coupled via a mechanism with the vehicle door. The electric motor is powered by a Controlled control device, wherein in an idle air guide the open position and at an operating position located in the air guide means the intermediate position is approached.

In a preferred embodiment, the air guiding device has a drive, an adjusting mechanism and a planar air guiding element. The air guiding device is actuated by the drive with the assistance of an external power, whereby an automatic or manually manually adjustable adjustment is possible. The air guide element preferably has a wing profile for increasing the output in the operating position.

In a preferred embodiment, the air guide element is arranged in the rest position Strkbündig. The air guide is so that it is flush with the surrounding body parts and accordingly provides little air resistance.

In a preferred embodiment, the louver is arranged in the region of a flow separation edge of the vehicle door. In the area of a stall edge, the spoiler has a particularly advantageous aerodynamic effect, but is particularly high in the operating position when the vehicle door is in the open position.

In a preferred embodiment, the vehicle door is designed as a tailgate. The tailgate can cover a trunk or engine compartment underneath and is located in the rear of the vehicle. The attachment of a louver on the tailgate increases according to the output on the rear axle.

If the vehicle flap according to the invention is used in a vehicle with a variable-height chassis (for example air suspension), then the intermediate position can additionally be adjusted taking into account the chassis height currently available.

Further details and advantages of the invention will become apparent from the following description of a preferred embodiment with reference to the drawings.

Therein, the figure shows a side view of a vehicle with vehicle flap and adjustable louver.

According to the figure has a vehicle 1 a vehicle flap designed as a tailgate 2 which is pivotable between a closed position A and an open position B. In the area of a stall edge 2a is a Luftieiteinrichtung 3 arranged, which is adjustable between a straight-line rest position and an extended operating position. The Luftielteinrichtung 3 consists of one inside the vehicle door 2 arranged drive 3c that is on an adjustment mechanism 3b acts so that the aerodynamically effective and flat trained air guide 3a can be adjusted. The drive 3c is from a controller 7 automatically or manually influenced. The vehicle flap 2 is from a body-side drive 5 by means of a coupling rod 6 pivotable. The drive 5 is by means of a control device 4 controllable. Between the controller 7 for the louver 3 and the controller 4 there is a data exchange, the vehicle door 2 from the drive 5 can only be spent in the open position B, if the louver 3 at rest. Is the louver 3 as shown in the figure, but in the operating position, so the vehicle door 2 from the drive 5 only pivoted to an intermediate position C. The intermediate position C is chosen so that of the open position B is an adjustment D to the the air guide 3a in the operating position via the vehicle flap 2 protrudes, deducted.
