Description

Covering device and vehicle with same

Technical Field

The present invention relates to a covering device for covering a charging device of a vehicle, in particular an electric vehicle, having the features of the preamble of claim 1.

Background

The term "charging device" includes any device by which energy or energy carriers can be provided to the vehicle to drive the vehicle. Such a device is in particular a socket for a charging cord for charging an electric vehicle. However, the term "charging device" also includes a fuel filler (Tankstutzen) of a vehicle with an internal combustion engine through which fuel is delivered as an energy carrier to a tank of the vehicle.

A generic type of covering device for a charging device of a vehicle is known from publication DE 102015220484 A1. This publication describes a covering device for a fuel filler opening of a motor vehicle. The covering device comprises a cover bracket with a bearing surface, and the cover is fixed on the bearing surface. The cover bracket is pivotable about a pivot axis and is secured to the bracket of the covering device via the pivot axis. The bracket is provided with a fuel filler. If the covering device is in the open position, the cover is flipped open and pivoted outwards so that the vehicle can be refueled. In the closed position, the lid is folded up. In the closed position, the cover forms part of a visible bodywork cover (karosserieverleidung) of the motor vehicle and closes the filler opening from the outside in an inaccessible manner. In the case of a cover carrier which is locked by the central locking mechanism in the closed position, together with the cover, in the event of a failure of the central locking mechanism, the cover can no longer be opened as planned and thus the vehicle can no longer be refueled, the cover can be released and removed from the cover carrier by a manually translationally movable movement along the bearing surface of the cover carrier. The removal and release of the cover from the cover bracket can be referred to as "emergency unlocking". The cover holder has an opening in the region of the support surface, through which the spout can be inserted when the cover is removed, even if the cover holder is still in the closed position. A disadvantage of the known covering device is that special tools are required for emergency unlocking. Furthermore, the disadvantage is that the cover may be scratched and damaged by the tool during the emergency unlocking.

Disclosure of Invention

The object of the invention is therefore to propose an alternative emergency unlocking for a covering device.

According to the invention, this object is achieved by a covering device having the features of claim 1. The invention also comprises a vehicle, in particular an electric vehicle, having a covering device according to the invention according to claim 15.

The covering device according to the invention is used for covering a charging device of a vehicle, for example a charging socket for charging a battery of an electric vehicle, or for covering a fuel filler opening of a fuel-powered motor vehicle. The covering device comprises a cover, a cover bracket and a bracket. The cover support is mounted on the support in a movable manner, so that the cover can be moved together with the cover support from the closed position into the open position and from the open position into the closed position again. The covering device can be fixed in a position on the body of the vehicle or on the body cover by means of a bracket. Movement of the cover from the closed position to the open position is necessary in particular for refueling or charging of the vehicle, since in the closed position the cover covers the charging device and prevents access to the charging device from the outside. The cover forms part of a visible bodywork cover, in particular in the closed position. However, in the open position the cover is arranged such that the charging device is accessible, in particular from the outside, i.e. from the outside of the vehicle, for charging, so that for example a plug can be plugged into the socket for charging the vehicle battery.

For example, the cover carrier is arranged on the carrier in a rotatable, pivotable and/or movable, in particular translationally movable manner, for example via at least one slotted track as a guide in which the cover carrier is arranged in a translationally movable manner. The cover holder is in particular moved in a motor-driven manner and/or the cover holder is locked or closed in a motor-driven manner relative to the holder, so that unintentional opening, i.e. unintentional movement of the cover holder from the closed position into the open position, is not possible.

If the drive motor or power required for movement or locking is faulty or insufficient, it may happen that the cover together with the cover holder cannot be moved from the closed position into the open position. For example, when the battery of the electric vehicle is overdischarged such that there is no longer sufficient energy for the movement of the lid support together with the lid into the open position and the lid support remains in the closed position, then the battery of the vehicle cannot be charged even when the lid is closed.

In this case, the invention provides that the cover can be moved relative to the cover support and relative to the support from the closed position into the emergency unlocking position. The term "emergency unlocked position" means that the covering device can, but does not have to, have a locking element. Embodiments without a lock are conceivable in which the emergency unlocking position forms an alternative open position that can be reached manually. In the emergency unlocking position, the cover does not cover, at least does not cover, the charging device completely. Furthermore, the cover holder has an opening through which a plug or a spout can be inserted into the charging device through the cover holder when the cover holder is in the closed position and the cover is in the emergency unlocking position.

The opening extends in particular through a support surface of the cover support, against which the cover rests in the closed position.

According to the invention, the cover is pivotably mounted on the cover carrier such that the cover can be pivoted relative to the cover carrier from the closed position into the emergency unlocking position. By pivotable is here meant in particular that the cover is rotatable about a rotational axis by means of which it is firmly connected to the cover holder. However, the term "pivotable" also includes, for example, the placement of the lid on the lid support by means of four links or a combination of a rotational movement and a translational movement of the lid relative to the lid support. By pivotable it is meant in particular that the entire lid or at least a partial region of the lid is moved axially and radially relative to the lid holder, in particular relative to a support surface of the lid holder, against which the lid rests in the closed position. For example, when the cover is pivoted relative to the cover holder about a rotation axis formed by a fixed-position rotation bearing, all parts of the cover-except the parts arranged directly on the rotation axis-move axially and radially relative to the cover holder during pivoting. The cover support is in particular a type of carriage on which the cover is arranged pivotably about a pivot axis and by means of which the cover is movable relative to the support. The advantage of the cover pivoting relative to the cover bracket is that the cover can be moved in a simple manner so that it does not collide with the bodywork cover surrounding it in the closed position, which may result in damage to the cover and/or the bodywork cover.

The cover is in particular not completely released from the cover holder, but is firmly, however movably connected to the cover holder via a pivot axis. The cover is thus also held firmly on the cover holder in the emergency unlocking position. This has the advantage that the cover does not have to be completely removed from the cover holder, wherein it may be scratched or otherwise damaged or lost.

The covering device preferably has a spring element which acts on the lid in the closed position in a manner towards the lid support or away from the lid support. The spring element may be, for example, a torsion spring, which is arranged on a rotation axis about which the cover can pivot in a rotational movement relative to the cover holder.

If the spring element acts on the lid towards the lid support, the spring element holds the lid in the closed position due to the spring force. In this case, the cover can be moved by a person, for example by the driver, from the closed position into the emergency unlocking position against the spring force by hand. In this embodiment, an additional locking means for preventing the transfer into the emergency unlocking position is not absolutely necessary.

If the spring element acts on the lid in a manner remote from the lid support, the lid can also be in an emergency unlocking position if it is not locked to the lid support in the closed position. The cover device according to the invention therefore has, in a preferred embodiment, a locking element which locks the cover in the closed position toward the cover holder and releases the cover after unlocking in order to transfer the cover into the emergency unlocking position. The locking element can be mechanically unlocked, for example, by means of a tool which is arranged externally on the covering device. In addition or alternatively, the unlocking element can be set from the vehicle interior, for example by means of a handle or a button in the passenger compartment. The locking element ensures that the cover is only transferred into the emergency unlocking position when required. Thereby excluding, among other things: when the cover support is not in the closed position but, for example, in the open position, the cover is pivoted into the emergency unlocking position, in which the cover support is moved in such a way that the cover is positioned "sunk" behind the bodywork protection surface. Furthermore, in the open position there is a risk that the cover may strike the bodywork cover when pivoted into the emergency unlocking position and that the cover may be damaged when the cover carrier is moved back into the closed position with the pivoted-open cover.

In order to prevent the lid from being accidentally unlocked when the lid support is in the open position, it is preferred that the first part of the locking member is on the lid and/or on the lid support and the second part of the locking member is firmly connected to the support, wherein said connection can be accomplished directly or indirectly via another member. The second part is arranged in particular in a stationary manner on the support, so that the first part can be moved together with the lid support or the lid relative to the second part when the lid support is moved from the closed position into the open position. The two parts of the locking element are preferably decoupled from the operative connection, so that the locking element can no longer be unlocked and released for transferring the cover into the emergency unlocking position. The two parts of the locking element are preferably disconnected after a short displacement distance of the cover holder, in particular after 20% of the displacement distance traveled by the cover holder from the closed position into the open position, in particular less than 10% of the displacement distance. The cover holder is moved in particular not more than 10 cm, in particular not more than 5 cm, in particular not more than 2.5 cm, in particular less than 1 cm, before the two parts are disconnected. The shorter the travel sufficient to disengage the locking element from the operative connection, the lower the risk of the cover being damaged by accidental upward pivoting (Aufschwenken) into the emergency unlocking position

The covering device according to the invention preferably has an actuating element, preferably a mechanical or electrical actuating element, which is preferably connected to the support such that the actuating element does not act on the locking tongue in the open position in order to unlock the locking tongue. The operating element can be connected directly or indirectly to the support. The actuating element is arranged in particular in a stationary manner on the support. However, the actuating element is also arranged such that it can act on the locking bolt in the closed position for unlocking.

In a preferred embodiment of the covering device according to the invention, the locking element comprises at least one mechanical actuating element which acts on the locking tongue in order to unlock the locking tongue of the locking element. The locking tongue is arranged in particular in a stationary manner on the cover support, and is preferably rotatably mounted. The locking tongue engages in particular in a catch (belle) which is arranged fixedly on the lid and with which the locking tongue locks the lid against upward pivoting into the emergency unlocking position. By actuating the mechanical actuating element, the mechanical actuating element acts on the locking bolt, whereby the locking bolt is moved away from the catch, in particular, so that the cover is pivoted upwards into the emergency unlocking position, in particular, due to the force of the spring element.

The mechanical actuating element is in particular a pivot lever, which is in particular rotatably mounted. The pivot lever is in particular rotatably mounted on a swivel bearing which is fixed in position relative to the support. The swivel bearing is in particular fixed to the support or it is integral with the support.

It is furthermore preferred that a mechanical unlocking element is provided for unlocking, which forms part of the locking element of the covering device according to the invention and which acts on the mechanical operating element. The mechanical unlocking element is in particular a pulling element, such as a rope or a soft sleeve wire (bowden zug), with which the locking element can be operated, for example, from the passenger compartment of a vehicle equipped with the covering device according to the invention for emergency unlocking of the cover.

Alternatively or in combination, the locking element of the covering device according to the invention comprises at least one electrically operated element which acts on the locking tongue to unlock the locking tongue of the locking element. The actuating element is preferably a magnetic switch, in particular a lifting magnet, which moves the locking bolt, in particular when a voltage is applied, so that the locking bolt is unlocked, whereby the cover is released and can be moved into the emergency unlocking position, in particular by a spring element acting on the cover. In this embodiment according to the invention, an electrical line is preferably provided for unlocking, which is connected to the electrical actuating element. A voltage can be applied to the electrically operated element via the wire. The wire, in particular a USB wire, via which a voltage can be applied to the electrically operated element of the locking piece of the covering device according to the invention for unlocking and releasing the cover by means of a mobile power supply or a mobile device, for example a smart phone using USB-OTG.

If the operating element is an electrical operating element, the line preferably has a switch which is closed in the closed position and which is open in the open position, in particular after a short displacement path of the cover holder, so that a voltage can no longer be applied to the electrical operating element via the line for unlocking. Thus, unlocking in the closed position is only possible when the switch is closed.

The covering device according to the invention preferably has a safety element which ensures that the cover holder cannot be moved into the open position when the cover is in the emergency unlocking position. The safety element can be, for example, a locking mechanism which, in the emergency unlocking position of the cover holder, unlocks the drive mechanism of the cover holder and, for example, decouples the coupling, so that the cover holder cannot be moved into the open position. Alternatively and preferably, the covering device according to the invention has a sensor element, in particular a hall sensor, as a safety element. The sensor element monitors whether the cover is in the closed position or in the emergency unlocking position. The sensor element works in such a way that the lid holder can only be moved from the closed position into the open position if the sensor element reports that the lid is not in the emergency unlocking position, which might otherwise lead to damage of the lid in the movement of the lid holder. The sensor element is coupled in particular with an electric drive unit for the cover holder in the following manner: the electric drive unit can be activated only when the lid is in the closed position for moving the lid support into the open position.

In order to return the locking bolt to the position after unlocking the cover, a return spring can be provided, which returns the locking bolt again after unlocking. If, after charging, the cover is moved from the emergency unlocking position into the closing position by the driver manually counter to the force of the spring element, the locking bolt can again be locked in the catch by the return spring and the cover can be locked in the closing position.

Detailed Description

The covering device shown in the figures below is shown in the closed position in fig. 1 to 3 and in fig. 6 and 7, respectively, with the symbol "a", in the open position in the figure with the symbol "b", and in the emergency unlocking position in the figure with the symbol "c".

Fig. 1a to 3c show a first covering device 1 according to the invention. The covering device 1 according to the invention is used for covering a charging device 2 of a vehicle, in the embodiment for covering a socket of an electric vehicle, not specifically shown. The covering device 1 and the charging device 2 are parts of an electric vehicle, wherein in the drawing, apart from the covering device 1 and the charging device 2, only the part of the bodyshell 3 surrounding the covering device 1 is depicted. The covering device 1 comprises a cover 4, a carriage-type cover bracket 5 and a guide 6 arranged on a plate-type bracket 39. In the embodiment of fig. 1a to 3c, the guide 6 is a slotted guide, which is constructed on two webs 40 arranged on the bracket 39. In the tab 40, the guide groove is arranged as a slide groove 27 in a manner known per se. The guide pin 37 of the cover holder 5 engages in the slide groove 27. By this engagement, the cover holder 5 is movably arranged in the guide 6. The cover 4 can be moved together with the cover support 5 in the web 40 and relative to the web 40 or relative to the support 39 from the closed position (fig. 1a, 2a, 3 a) into the open position (fig. 1b, 2b, 3 b), in this case in a carriage-like manner, in which the cover support 5 is moved back under the bodyshell 3, as seen from the outside, together with the cover 4. In the closed position, the cover 4 completely covers the charging device 2, i.e. in the closed position the cover 4 forms a common outer surface together with the bodyshell 3 surrounding the cover 4 in the closed position and is thus part of the vehicle housing in the closed position, as can be seen in fig. 1a, which is a view of the vehicle from the outside. Thus, in the closed position the charging device 2 is not accessible from the outside. However, this also means that when the cover 4 is in the closed position, an external charging plug without a charging station can be plugged into the charging device 2 and thus cannot charge the electric vehicle. The covering device 1 is connected to the body cover 3 via a bracket 39. For the sake of clarity, the bodyshell 3 and the charging device 2 are not shown in fig. 2a to 3c, but only the components of the covering device 1.

If the electric vehicle is to be charged, the cover holder 5 is moved together with the cover 4 fastened to the cover holder 5 by means of a not-shown motor from the closed position into the open position. The cap holder 5 moves together with the cap 4 along a movement stroke w in the guide 6. Thereby, the cover 4 is pushed almost completely under the bodyshell 3 and the opening 24 is released, so that the charging device 2 can now be accessed from the outside for charging, which is shown in fig. 1 b. After charging, the cover holder 5 is again moved motor-driven together with the cover 4 into a closed position in which the cover 4 again covers the opening 24 (fig. 1 a).

In the case of the cover support 5 together with the cover 4 not being movable from the closed position into the open position, for example when the battery of the electric vehicle is dead and thus the cover support 5 cannot be moved motor-driven, the cover 4 can be moved from the closed position into the emergency unlocking position relative to the cover support 5, wherein the cover support 5 cannot be moved and remains in the closed position. The cover holder 5 has a recess 38 which forms an opening 24 when the cover 4 is in the emergency unlocking position, which opening is released by the cover 4 in the emergency unlocking position, so that the charging device 2 can be accessed from the outside and the electric vehicle can be charged.

The cover 4 is pivotably mounted on a cover bracket 5. The pivoting takes place here as a rotation about an axis of rotation 8 which extends perpendicularly to the displacement path w and which is arranged parallel to the bodyshell cover 3. On the rotation axis 8, a spring element 7, i.e. a torsion spring, is arranged, which acts on the lid 4 outwardly away from the lid support 5, i.e. in the direction of the emergency unlocking position, and which enables the lid 4 to be pivoted automatically and outwardly and upwardly about the rotation axis 8 from the closed position into the emergency unlocking position relative to the lid support 5, as can be seen in fig. 1 c.

In order to prevent the cover 4 from being pivoted upwards unintentionally by the spring element 7, the covering device 1 has a locking element 9, which is shown enlarged in fig. 3a to 3 c. The locking member 9 locks the lid 4 in the closed position and also against the lid support 5 in the open position such that the lid 4 cannot move relative to the lid support 5 but can only move therewith. For unlocking, a mechanical unlocking element 18 with a soft sleeve wire 19 and a release lever 20 arranged in the vehicle interior is provided in the embodiment of fig. 1a to 3 c. The locking element 9 in the closed position is unlocked by operating the release lever 20, whereby the locking element releases the cover 4 and the cover is transferred from the closed position into the emergency unlocking position by the spring element 7. The locking element 9 consists of two parts: the first part 10 on the lid 4 and the lid holder 5 and the second part 11 directly on the holder 39 and firmly connected thereto. The first part 10 comprises an L-shaped catch 17 which is integrally and fixedly arranged on the rear side of the cover 4 and in which a first end of an S-shaped locking tongue 15 engages for locking. The locking bolt 15 is rotatable about and is mounted on a rotary bearing 16, by means of which it is arranged in a stationary manner on the lid support 5. For unlocking, a first end of the mechanical actuating element 12, which forms the second part 11 and is formed here as an L-shaped pivot lever 13 and is rotatably mounted on a further swivel bearing 14, acts on a second end of the S-shaped locking tongue 15. The pivot lever 13 is connected to the support 39 by its pivot bearing 14 in a stationary manner. A flexible sleeve wire 19 is secured to the second end of the pivot rod 13. If pulled at the soft sleeve wire 19 via the release lever 20, this results in a rotational movement of the pivot lever 13 about its rotational bearing 14, so that in the closed position shown in fig. 2a and 3a, the first end of the pivot lever 13 is pressed against the second end of the locking bolt 15. Thereby, the lock tongue 15 is rotationally moved around its rotational bearing 16, whereby the first end of the lock tongue 15 is moved away from the catch 17 and disengaged. The movement of the individual components is illustrated by arrows in fig. 3 c. At this point, the cover 4 is unlocked and released, so that it pivots outwards and upwards into the emergency unlocking position due to the force of the spring element 7 and releases the charging device 2, which is shown in fig. 1 c.

In order to prevent the "locking element 9 from being unlocked when the lid carrier 5 is in the open position together with the lid 4 and thus below the bodyshell 3, which can lead to the lid 4 possibly striking from the inside toward the bodyshell 3 and possibly being scratched or otherwise damaged by bearing against the bodyshell 3 when moving into the closed position", the locking element 9 is designed such that the two parts 10, 11 of the locking element 9 are disconnected from the active connection when the lid carrier 5 is moved from the closed position into the open position. As can be seen in fig. 3a and 3b, a short movement of the cover holder 5 in the direction of the displacement path w is sufficient, so that the pivot lever 13 no longer acts on the locking tongue 15 and the locking tongue can be moved away from the catch 17 for unlocking. By the pivot lever 13 being fixedly connected to the bracket 39 and the locking tongue 15 being fixedly connected to the cover bracket 5, a displacement travel w of several centimeters is sufficient to disengage the two parts 10, 11 of the locking element 9 from the operative connection. In the open position, the pivot lever 13 thus no longer acts as a mechanical actuating element 12 on the locking bolt 15.

In order to exclude the case that the cover holder 5 would be moved from the closed position into the open position when the cover 4 is pivoted open in the emergency unlocking position, the covering device 1 has a sensor element 21 as a safety element, which monitors whether the cover 4 is in the closed position or in the emergency unlocking position (see fig. 2a to 2 c). The sensor element 21 comprises a hall sensor 22 and a magnet 23 arranged on the cover 4 such that said magnet moves away from the hall sensor 22 when the cover 4 is pivoted to the emergency unlocking position. The hall sensor 22 detects the magnet 23 in the closed position and, in the emergency unlocking position, no magnet 23 is detected when it has been moved away from the hall sensor 22. The control of the motor for moving the lid support 5 allows the motor to be activated and thus the lid support 5 to be moved from the open position into the closed position only if the hall sensor 22 detects the magnet 23 in the closed position of the lid 4. Thus, unintentional movement of the cover holder 5 with the pivotally opened cover 4 is prevented. The hall sensor 22 is sufficient only for monitoring the position of the cover 4 at the beginning of the movement from the open position to the closed position, since the parts 10, 11 of the locking element 9 are already disconnected after a short displacement travel w and therefore no monitoring of the position of the cover 4 is necessary anymore.

In fig. 4 to 7c, three further embodiments of the covering device 1 according to the invention are shown. To avoid repetition, only the differences will be discussed below. The same reference numerals are used for the same or corresponding parts.

In fig. 4 and 5, a second and a third covering device 1 according to the invention are shown, whose basic structure consisting of a cover 4, a cover holder 5 and a guide 6 corresponds to the kinematic structure of the covering device 1 of the first embodiment of fig. 1a to 3 c. The difference from the first embodiment is that the two covering devices 1 of fig. 4 and 5 have, instead of mechanical operating elements, electrical operating elements 28 for unlocking the cover 4. In both embodiments the electrically operated element 28 comprises a magnetic switch 29 in the form of a lifting magnet 30.

In the second embodiment of fig. 4, the lifting magnet 30 replaces the pivot rod 13 and thus forms the second part 11 of the locking element 9. The pin 41 of the lifting magnet 30 acts on the second end of the bolt 15. If the lifting magnet 30 is activated, the pin 41 moves away so that it presses against the second end of the bolt 15 in the closed position. As in the first embodiment, the bolt 15 is pivoted about its swivel bearing 16 by the pressure exerted on the second end of the bolt 15 by the pin 41 in this case, and the first end of the bolt 15 is moved away from the catch 17 as a result of this swivel movement. After such unlocking, the cover 4 is moved away and due to the force of the spring element 7 into the emergency unlocking position.

In the third embodiment of fig. 5, the lifting magnet 30 not only replaces the pivot lever 13, but the pin 41 of the lifting magnet 30 itself forms the locking tongue 15 which engages in the catch 17 in the closed position and locks the lid 4 to the lid support 5. If the lifting magnet 30 is operated, in this case the pin 41 is pulled back and out of the catch 17, whereby the locking element 9 is unlocked and the cover 4 is released, so that the cover 4 moves into the emergency unlocking position due to the force of the spring element 7.

For operating the lifting magnet 30, electrical leads 31 in the form of USB-OTG wires 32 are provided in both the second and third embodiments, via which the lifting magnet can be connected to an external power source 33, for example a mobile power source or a mobile telephone with a USB interface as shown here and can be supplied with power. Since the lifting magnet 30 only needs to be activated for a short time, only a low power of the external power supply 33 is required for this. For example, in the case of a corresponding selection of the lifting magnet 30, the power of the USB-OTG interface as the external power supply 33 is completely sufficient.

In the second embodiment of the covering device 1 according to the invention shown in fig. 4, the pin 41 of the lifting magnet 30 is no longer able to act on the second end of the locking bolt 15 due to the short movement of the cover bracket 5 in the direction of the displacement travel w, and as in the first embodiment, it is thus ensured that the cover 4 is not unintentionally pivoted upwards into the emergency unlocking position, whereas the third embodiment of fig. 5 has a two-part switch 34 for this purpose. The first portion 35 of the switch 34 together with the catch 17, the lifting magnet 30 and the first section 31a of the electrical conductor 31 form the first portion 10 of the locking element 9. The second portion 36 of the switch 34 and the second section 31b of the electrical conductor 31 together form the second portion 11 of the locking element 9 to which the external power source 33 can be connected. The first portion 35 of the switch 34 is arranged on the lid support 5 and the second portion 36 of the switch 34 is arranged on one of the tabs 40 and is thus fixed in position with respect to the support 39. After the cover holder 5 has been moved a few centimeters in the direction of the movement stroke w, the two parts 35, 36 of the switch 34 no longer contact each other. They are thus disconnected from the operative connection, so that the electrical leads 31 to the lifting magnet 30 are interrupted and the lifting magnet 30 can no longer be supplied with power to unlock the cover 4. If the cover holder 5 is not in the closed position, after a short displacement path w, the cover 4 can no longer be unintentionally unlocked for movement into the emergency unlocking position.

The fourth embodiment shown in fig. 6a to 7c corresponds to the first embodiment of fig. 1a to 3c, except for the following differences: the cover holder 5 is arranged on a pivot arm 25 which is pivotably mounted on a pivot shaft 26 at two tabs 40. Instead of a carriage-like displacement as in the embodiment already described, in this embodiment the cover holder 5 together with the cover 4 is pivoted from the closed position about the pivot axis 26 into the open position, whereby the two parts 10, 11 of the lock are disconnected from the operative connection. The unlocking of the locking element 9 takes place mechanically as in the first embodiment via a mechanical unlocking element 18, which here also comprises a release lever 20 and a soft sleeve wire 19. Alternatively or additionally, an electrically operated element can also be provided here.

In all embodiments, a return spring (not shown) may be provided, for example, for moving the locking tongue 15 back after unlocking the lid 4, so that if the lid 4 is moved from the emergency unlocking position into the closed position after charging by the force of the driver manually counteracting the spring element 7, the locking tongue 15 locks in the catch 17 and the lid locks at the lid holder 5 in the locking position.

The covering device according to the invention is characterized by a simple structure which prevents the cover 4 from being damaged or lost in the event of an emergency unlocking.
