AI Technical Summary

Problems solved by technology

[0008] The system has the disadvantages of high opening forces (preload of strong springs, sealing force) and high locking noise, since the cover has to be dropped from a height of at least 20 cm in order to fall reliably into the lock
[0009] Purely electric systems are comfortable, but can cause large damage due to control commands (eg unintentional opening commands)
To avoid this, a particularly complex electronic system is required
Due to the lack of mechanical redundancy, an emergency opening concept via emergency power supply is additionally required

Embodiment Construction

[0022] exist figure 1 shows the first level of the control panel 1 together with the associated movable components. The control disc 1 is rotatable about its axis 2 . The approximately triangular control contour 3 for pivoting the ejector lever 4 is located above the gear wheel 12 in the first layer. The control contour 3 likewise extends in an arc in the region adjoining the edge region of the gear wheel 12 in order to be able to hold the ejector lever 4 in the lowered position and the control disk 1 to still be able to rotate for a controlled movement of the other components. The ejector rod 4 can swing around the axis 5 . When the corresponding cover is closed, the catch or stop 6 of the cover finally abuts against the free end 7 of the lever arm 8 of the ejector lever 4 . If the catch 6 rests against the free end 7, the cover can be lifted or lowered by swiveling the ejector rod 5 in the following way: If the control disc 1 is turned counterclockwise, the control profil...

Abstract

The invention relates to a closing device, comprising a locking mechanism, which has a rotary latch and at least one pawl for locking the rotary latch. The closing device comprises an electric drive for moving components of the closing device. The present invention is especially advantageous for front hoods or front flaps, which are located in the front as viewed in the typical direction of travel of a motor vehicle. The invention further relates to a method for closing a hood by means of a closing device according to the corresponding claims. The present invention aim to be able to suitably move and control a plurality of components in such a closing device without having to make an excessive technical effort therefor. The invention should preferably enable a purely electrically operated hood lock having locking, opening, and closing functions. In order to achieve the aim, a closing device having a locking mechanism comprises a control disk, by means of which at least two components, preferably at least three components, of the closing device can be moved by means of rotation of the control disk. Thus, for suitable movement of a plurality of components, it is only necessary to rotate the control disk by rotation by means of an electric drive in order to be able to close and/or open a door or flap.

Description

technical field [0001] The invention relates to a locking device with a locking mechanism comprising a rotary locking fork and at least one pawl for locking the rotary locking fork. The locking device includes an electric drive for moving components of the locking device. The invention is particularly advantageous for a front hood or bonnet which is located at the front as viewed in the usual direction of travel of the motor vehicle. The invention also relates to a method for closing a cover. Background technique [0002] Locking devices are used to temporarily lock openings in motor vehicles or buildings by means of doors or flaps. In the locked state, the rotary locking fork engages with two arms an in particular arc-shaped stop / bolt (also referred to as catch) and is locked by means of the pawl. At this time, the stopper cannot leave the locking mechanism. For opening, the pawl must be moved out of its locked position. The rotary latch can be pivoted towards the open...
