Description

The invention relates to an opening and closing device for a motor vehicle according to the preamble of claim 1.

Motor vehicles have flaps or covers on the bodywork that cover, for example, a charging recess in electric vehicles or a fuel filler neck in vehicles with combustion engines. The flap can be folded up to the side, for example, when the electric vehicle is to be charged and the charging recess must be accessible. When closed, the flap should shield or insulate the charging recess as well as possible from external and environmental influences. For this purpose, a seal is usually provided on which the flap sits when closed.

To charge an electric vehicle, the charging bay must be accessible at the desired time; in particular, the driver should be able to open the flap without using tools. External influences such as extreme cold, ice or snow can make it very difficult to operate the flap. Icing in particular can make opening and closing the flap difficult. For example, in heavy snowfall, it can be difficult to bypass the seal when closing the flap.

Actuators can be used to assist the user in operating the valve mechanically. EN 10 2013 109 961 A1 discloses a locking mechanism with a link and locking pin for keeping lids in motor vehicles closed.

From the EN 10 2013 212 772 A1 A locking device for a glove compartment of a vehicle is known, which has a motor-driven rotary axis with at least one worm guide.

Also from the EN 10 2022 107 707 B3 A drive device for a vehicle flap is known.

From the EN 10 2021 002 425 A1 A vehicle flap with an opening and closing device is known, which comprises an opening and closing device with a sliding and pivoting device which is coupled to a gear transmission.

The EN 10 2022 107 707 B3 relates to a drive device for a vehicle flap, by means of which an opening in a vehicle body can be closed and opened. In the installed position of the drive device, during an adjustment from a position closing the opening in the direction of a position opening the opening, the vehicle flap first carries out a lifting movement inwards in the transverse direction of the vehicle (y) and then a combined sliding and rotating movement within the vehicle body. The inward-opening vehicle flap can be adjusted by means of a combination of a rotary joint mechanism and a linear guide, wherein the rotary joint mechanism and a carriage of the linear guide can be driven by a drive unit via a lever arrangement.

The invention is based on the object of providing a device for a vehicle with a flap, which supports the user in opening and closing the flap.

This object is achieved with an opening and closing device for a motor vehicle according to claim 1.

The invention relates to an opening and closing device for a motor vehicle, comprising a rotatably and/or pivotably mounted flap, in particular a charging flap for an electric vehicle.

The flap can be adjusted between an open and a closed position by means of a translatory and rotary movement using an electric motor drive.

For this purpose, the flap has at least one driver which is guided in a guide structure of a link arm for adjusting the flap and is connected to the drive via at least one pivot lever which is rotatably coupled to a drive shaft of the drive.

The drive causes the at least one pivot lever to pivot via the drive shaft in order to displace the at least one driver coupled to the at least one pivot lever in order to adjust the flap between the open and closed positions in the guide structure.

In other words, the at least one driver arranged on the flap is displaced in the guide structure in such a way that the flap executes an opening or closing movement. For this purpose, the at least one driver is coupled to the pivot lever, which in turn is coupled to the drive or the drive shaft of the drive. If the drive is activated, ie the electric motor causes the drive shaft to rotate, then the pivot lever is pivoted. As a result, the at least one driver coupled to the pivot lever is displaced in the guide structure. ture of the link arm - which is fixed relative to the flap - is displaced, whereby the flap connected to at least one driver is also moved.

According to a first embodiment of the invention, the guide structure is designed such that the drive acts directly or rigidly on the at least one pivot lever, in particular that the pivot lever is connected directly or rigidly to the drive shaft, preferably by means of a force or form fit, for example a polygon connection, so that when the drive is activated, the drive shaft directly drives the pivot lever.

The structure of the device and its assembly are significantly simplified because the at least one pivot lever is directly or rigidly connected to the drive or drive shaft. A direct connection means that, for example, no gears or other gear parts are arranged in the power flow between the pivot lever and the drive or drive shaft. The drive acts directly on the pivot lever, which means that the kinematics of the device are significantly simplified compared to the prior art, in which gears or transmissions are provided. A self-locking closed flap, in particular a loading flap, is also realized.

According to a further development of the invention, the at least one pivot lever for coupling the at least one driver to the pivot lever has an opening, for example an elongated hole, into which the driver is inserted.

In this way, the components can be easily coupled by plugging the driver together or inserting it into the slot in the pivot lever and, on the other hand, the driver can be flexibly guided in the slot. In addition, the slot ensures that the position of the drive shaft can be freely selected depending on the requirements of the installation space. In particular, the drive shaft can be arranged at different points on the device depending on the geometric design of the slot. Preferably, the drive shaft can be positioned depending on the design of the link arm and the specified installation space due to the play provided by the slot.

At least two drivers can be connected by means of a sliding block, whereby the sliding block can be guided in the guide structure.

In this way, the flap is securely connected to the device via the drivers, as several coupling points (drivers) are provided. Even a defect in a single driver would not immediately lead to a failure of the device. The drivers arranged on the link slide are moved synchronously by their mechanical connection. It can be provided that the link slide is guided in a cavity inside the link arm. This allows the installation space of the entire device to be further optimized.

In particular, it is advantageous that a guide structure is arranged on two opposite sides of the flap, into which a driver engages, wherein a pivoting lever is arranged on both sides of the flap.

The pivot lever can engage a single driver on each side of the flap and additional drivers on each side of the flap can be carried along by the sliding gate. However, it is also conceivable to arrange just one (single) driver on the sliding gate.

For particularly stable and safe guidance of the flap, a pivot lever can be provided on two opposite sides of the flap, into which a driver engages. These drivers can in turn be arranged on a sliding block, each of which has further drivers that are also guided in the guide block for synchronous movement.

In particular, the guide structure can be designed in such a way that it enables the flap to be pivoted in a range of up to 110°, in particular up to approximately 90°.

In this way, due to the shape of the guide structure, the flap can, for example, first perform a (linear) lifting movement and then a rotating or pivoting movement for complete opening, so that the flap is then moved by approximately 110°, in particular 90°, from the closed position into the fully open position. During the closing movement, the flap can then be moved from the open position by approximately 110°, in particular approximately 90°, into the closed position. Here, too, a (linear) lifting movement can be provided for complete closing.

According to an advantageous development of the invention, the drivers for an opening movement of the flap are first guided in a linear section of the guide structure and then in a curved path in the guide structure, so that the flap initially has a lifting movement and then a rotating or swiveling movement.

In a variant of the invention, the drive is arranged on the link arm or on a housing of the device. In this way, the structure of the device can be simplified overall, since no additional holding devices or the like are necessary. The device can be manufactured with comparatively few components. Neither the link arm nor the drive are moved relative to the flap; they are stationary, for example, relative to a vehicle in which this device can be arranged to open a flap.

The at least one driver can be designed as a bolt or pin which penetrates the guide structure, preferably essentially vertically. This advantageous design can also further simplify the structure of the device. This is because the bolts or pins can be easily coupled to the pivot lever by inserting them, for example, into the elongated hole in the pivot lever and guiding them there.

The two pivot levers can be connected to each other by means of the drive shaft for synchronous movement. This also makes the overall structure even simpler. In particular, only a single drive is required for synchronous movement of the drivers or the sliding gate, rather than one drive on each side of the flap.

The flap can be designed as a charging flap for an electric charging trough.

Further aims, advantages, features and possible applications of the present invention will become apparent from the following description of an embodiment with reference to the drawings. All described and/or illustrated features form the subject matter of the present invention, either individually or in any meaningful combination, regardless of their summary in the claims or their reference back to them.

• 3 a side view of another embodiment of the device according to 1 .

In the following figures of the drawing, identical or equivalent components are provided with reference symbols based on an embodiment in order to improve readability.

1 shows an embodiment of an opening and closing device 10 according to the invention for a motor vehicle. In the present case, the device 10 has a rotatably and/or pivotably mounted charging flap 1 for an electric vehicle, which covers a charging recess.

How 1 As further shown, the flap 1 is adjustable between an open and a closed position by means of a translatory and rotary movement using an electric motor drive 2.

In order to realize this adjustability of the flap 1, the flap 1 in the design variant according to 1 In this case, a bolt-shaped driver 3 on the side 13 of the flap 1 with the drive 2 (cf. 3 ) and two drivers 3 on the opposite side 14 of the flap 1 (cf. 2 ) which are guided in a guide structure 5 of a link arm 6 for adjusting the flap 1. A driver 3 per side 13, 14 of the flap 1 is connected to the drive 2 via a pivot lever 8 which is rotatably coupled to a drive shaft 7 of the drive 2. The drive 2 is arranged on the link arm 6 (cf. 1 ), but can alternatively be arranged on a housing or housing part of the device 10.

The 2 shows a side view of the device 10 according to 1 in a partially opened position, with the flap 1 located in front of the cutting plane and therefore not visible in this figure. In 2 The side with the two drivers 3 can be seen. The 3 shows the opposite side of the device 10, in which only one driver 3 is provided. The drive 2 is also arranged on this side.

The drivers 3 are designed as bolts or pins and engage through the guide structure 5 into a guide structure of the sliding block 16 (cf. 2 and 3 ).

The drive 2 causes the pivot lever 8 to pivot via the drive shaft 7 in order to move the driver 3 coupled to the pivot lever 8 to adjust the flap 1 between the opening and closed position in the guide structure 5.

In other words, the driver 3 arranged on the flap 1 is displaced in the guide structure 5 in such a way that the flap 1 executes an opening or closing movement. For this purpose, the driver 3 is coupled to the pivot lever 8, which in turn is coupled to the drive 2 or the drive shaft 7 of the drive 2. If the drive 2 is now activated, i.e. the electric motor causes the drive shaft 7 to rotate, the pivot lever 8 is pivoted. As a result, the driver 3 coupled to the pivot lever 8 is displaced in the guide structure 5 of the link arm 6 - which is fixed relative to the flap 1 - as a result of which the flap 1 connected to the driver 3 is also moved.

How 1 further shows, the drive 2 acts directly or rigidly on the pivot lever 8 in that the pivot lever 8 is connected directly or rigidly to the drive shaft 7 by means of a force or form fit, for example a polygon connection, so that when the drive 2 is activated, the drive shaft 7 directly drives the pivot lever 8.

A direct connection means that, for example, no gears or other gear parts are arranged in the power flow between the pivot lever 8 and the drive 2 or the drive shaft 7. This significantly simplifies the kinematics of the device compared to the prior art, in which gears or gears are provided. A self-locking, closed loading flap is also realized.

The pivot lever 8 has an opening 15 for coupling the driver 3 to the pivot lever 8, in this case an elongated hole into which the driver 3 is inserted. The position of the drive shaft 7 can be freely selected depending on the requirements of the installation space, in particular the drive shaft 7 can be arranged at different points on the device 10 depending on the geometric design of the opening 15.

The 1 further shows that in the present case two drivers 3 are connected by means of a sliding slide 16 (see also 2 ) and the link slide 16 is guided in the guide structure 5. The drivers 3 arranged on the link slide 16 are moved synchronously by their mechanical connection. In the present case, the link slide 16 is guided in a cavity inside the link arm 6. This applies to the link slides 16 on both sides of the flap 1.

In the side views of the 2 and 3 the link carriage 16 can be seen, which in this case is kidney-shaped. This link carriage 16 slides in the link arm 6.

For a secure adjustment of the flap 1, a guide structure 5 is arranged on two opposite sides 13, 14 of the flap 1, into which a driver 3 or a sliding block 16 engages, wherein a pivoting lever 8 is also arranged on both sides 13, 14 of the flap 1.

The two pivoting levers 8 are connected to each other for synchronous movement by means of the drive shaft 7.

In particular, the pivot lever 8 engages a single driver 3 per side 13, 14 of the flap 1 and a further driver 3 on one of the sides 13, 14 of the flap 1 is carried along by the sliding block 16.

In the present embodiment, the guide structure 5 is designed such that it enables the flap 1 to be pivoted in a range of up to 110°, in particular up to approximately 90°.

To enable easy opening of the flap 1, the drivers 3 are initially guided in a linear section of the guide structure and then in a curved path in the guide structure 5, so that the flap 1 initially performs a lifting movement and then a rotating or pivoting movement in the opening direction.

In this way, due to the shape of the guide structure 5, the flap 1 can first perform a (linear) lifting movement and then a rotating or pivoting movement for complete opening, so that the flap 1 is then moved by approximately 110°, in particular 90°, from the closed position into the fully open position. During the closing movement, the flap 1 can then be moved from the open position by approximately 110°, in particular approximately 90°, into the closed position. Here, too, a (linear) lifting movement can be provided for complete closing.
