Furthermore, the invention relates to a loading device for a motor vehicle with such a loading flap device, as well as to a motor vehicle with such a loading device. In addition, the invention relates to an arrangement of a loading flap device on a component of a motor vehicle according to the preamble of claim 8, and to a method for operating a loading flap device for a motor vehicle according to the preamble of claim 9.
[0003] DE 102020 120242 A1 discloses a mechanism for pivoting a loading flap on a loading recess received or receptacle received in a body component of a motor vehicle, wherein the mechanism is designed to pivot the loading flap reversibly between a first orientation and a second orientation by superposition of at least two circular rotational movements with different radii of rotation, at least temporarily occurring simultaneously, or at least one circular rotational movement and at least one linear movement.
[0004] The object of the invention is to provide a loading flap device for a motor vehicle, a loading device for a motor vehicle, a motor vehicle, an arrangement of a loading flap device on a component of a motor vehicle, and a method for operating a loading flap device for a motor vehicle, in such a way that wear of the loading flap device can be kept particularly low.
[0005] This problem is solved according to the invention by a loading flap device for a motor vehicle with the features of claim 1, by a loading device for a motor vehicle with the features of claim 6, by a motor vehicle with a loading device with the features of claim 7, by an arrangement of a loading flap device on a component of a motor vehicle with the features of claim 8, and by a method for operating a loading flap device for a motor vehicle with the features of claim 9. Advantageous embodiments of the invention are the subject of the dependent claims and the description.
[0006] A first aspect of the invention relates to a loading flap device for a motor vehicle. The motor vehicle is, for example, a car, in particular a passenger car. Preferably, the motor vehicle, especially in its fully manufactured state, has the loading flap device. The loading flap device can also be referred to as a loading flap system.
[0007] The loading flap device comprises at least one loading flap. The loading flap can also be referred to as a cover element or simply as a flap. Furthermore, the loading flap device comprises at least one fastening device, in particular one designed separately from the loading flap, by means of which the loading flap can be pivoted about a pivot axis between a closed position and at least one open position, and in particular can be held or is held, at least indirectly or directly, on a component of the motor vehicle. This means that the loading flap can be attached or is attached to the component by means of the fastening device, whereby the loading flap can be displaced or is displaced about the pivot axis between the closed position and the open position.In other words, the loading flap is held or secured by the fastening device between the closed and open positions around the pivot axis on an outer surface, particularly on the outside, of the vehicle. Thus, the component is, for example, a component of the vehicle located on the outside. The component is, for example, a loading trough, which can also be referred to as a loading pot or loading compartment. Alternatively, the component is, for example, a body component of the vehicle. In particular, the component is designed separately from the loading flap device. Pivoting can be understood, in particular, as pivoting the loading flap relative to the component around the pivot axis.Furthermore, pivoting the loading flap can be understood to mean, in particular, pivoting the loading flap from the open position to the closed position and / or from the closed position to the open position.
[0008] Furthermore, the loading flap device has at least one drive unit, for example an electric one, by means of which the loading flap can be driven or is driven to pivot about the pivot axis, for example to pivot between the closed and open positions. This means that the pivoting of the loading flap about the pivot axis, for example, the pivoting of the loading flap between the closed and open positions, can be effected or is effected by means of the drive unit. In other words, it is provided that the loading flap can be pivoted or is pivoted about the pivot axis, for example, between the closed and open positions, by means of the drive unit.
[0009] In the closed position, a charging port, particularly an electrical one, for the vehicle's electrical energy storage device can be covered, in particular completely, by means of the charging flap. In other words, and specifically referring to the closed and open positions only, an opening can be covered in the closed position through which a charging element, particularly an electrical one, for the electrical energy storage device can be connected, preferably directly, to the charging port, can be connected, or is connected. This means that, and specifically referring to the open and closed positions only, the charging port or the opening can be closed, or is closed, by means of the charging flap in the closed position. Thus, in the closed position, the charging flap is closed.For example, the opening is limited or formed by the loading flap device and / or by a charging device of the vehicle. The connection device is, for example, part of the vehicle's charging device.
[0010] In the open position, the connection device of the loading flap can be, in particular completely, released. In other words, specifically with regard to the open and closed positions, the opening of the loading flap is, in particular completely, released in the open position. This means that in the open position, the connection device is not covered, nor is the opening covered. Thus, in the open position, the loading flap is, in particular, open.
[0011] The charging element is, for example, part of an external, particularly electrical, energy supply device related to the motor vehicle, which can also be referred to as an external charging device. The energy supply device is, for example, a charging station, a wallbox, or the like. The charging element is, for example, a charging plug. Charging the electrical energy storage device can be understood, in particular, as making the electrical energy storage device capable of being supplied with, or receiving, electrical energy via the connection device, especially through the charging element, in particular to recharge the electrical energy storage device. The term "electrical energy storage device" refers, in particular, to a battery or accumulator. Preferably, the electrical energy storage device is designed as an electrical traction storage device.This means that an electric machine can be supplied with energy, particularly energy stored or chemically bound in the electrical energy storage device, to power the motor vehicle. Therefore, the motor vehicle is, in particular, an electrically powered motor vehicle. In other words, the motor vehicle is preferably designed as a battery-electric vehicle or as a hybrid vehicle.
[0012] To minimize wear on the loading flap device, the loading flap device, according to the invention, comprises at least one position control device, in particular a data-transmitting, electrically or electronically and / or mechanically coupled to the drive unit, for example at least indirectly or directly, by means of which a protective position, which is an intermediate position with respect to the closed and open positions, into which the loading flap is to pivot, can be determined or is determined as a random position. In other words, it is provided that a target position for the loading flap can be determined or is determined as a random position, i.e., randomly, by means of the position control device, wherein the target position is or characterizes the intermediate position.The term "position control device" can therefore be understood to mean, in particular, a random number generator, or the position control device can incorporate a random number generator. The position control device can also be referred to as a position generation device or a position determination device. Determining the random position or the protective position can be understood, in particular, as specifying, defining, or determining the random position or the protective position. Determining the protective position or the intermediate position as a random position can be understood, in particular, as randomly determining the protective position or determining the protective position by means of a random number generator. This means, in particular, that at least one parameter required for determining the protective position can be generated, or is generated, by the position control device by random means, for example, by a random number.The random position can also be referred to as a random setting. Preferably, the protective position is a weather protection position, which can also be referred to as a weatherproof position.
[0013] Furthermore, it is provided that the loading flap can be pivoted, or is pivoted, around the pivot axis by means of the drive unit, for example, from the open position and / or from the closed position, into a specific, i.e., in particular, a previously determined, protective position or intermediate position. In other words, it is provided that the drive unit allows the loading flap to be adjusted to the specific or determined target position. This means that the loading flap, in its current position, i.e., to adjust or change the current position, can be pivoted, or is pivoted, around the pivot axis by means of the drive unit.Thus, the drive unit can actually move or pivot the loading flap into the previously determined protective position, especially as a random position.
[0014] The invention is based in particular on the following findings and considerations: Electric vehicles can typically be left outdoors for several hours while charging, i.e., during a charging process, and can therefore be exposed to the elements. To limit the effects of these elements, a weather protection position can be activated, especially with vertically opening charging flap systems, preferably as soon as the charging plug is connected to the vehicle, particularly to the charging port. For this purpose, it is conceivable to move the charging flap to an intermediate position, which is permanently stored in a memory unit and depends on the charging plug. The protective position to be moved to, or already moved to, can thus always be predefined.Alternatively, it is theoretically possible to have the charging flap move towards the charging plug in the closing direction, with a fixed position stored in the storage unit. This could be achieved, for example, by detecting a collision by means of an increase in the current consumption of the drive unit (also known as the actuator) at the moment it encounters an obstacle such as the charging plug. However, when using identical charging plugs, the same protective position can always be reached. Furthermore, the movement of the charging flap towards the charging plug, especially in charging flap systems without metal-reinforced hinge arms, can lead to an unsightly twisting of the flap system.
[0015] In contrast, the charging flap device according to the invention allows the pivoting, and in particular the approach, of the charging flap into the protective position by means of a random generator, by defining the protective position as a random position. The random generator can generate an absolute position which the charging flap, in particular an electric one, is to be approached, or is approached, subsequently. This ensures that the charging flap is not always moved into the same protective position when pivoting into it. This allows different protective positions to be approached particularly frequently. Therefore, due to the random position, the pivoting of the charging flap into the protective position always, or at least very frequently, occurs differently, that is, in different ways.This allows for particularly low wear, especially on one side, of the loading flap mechanism, for example, a moving part of the flap. Wear can be especially consistent, thus reliably preventing local wear peaks that could lead to failures and / or damage. Furthermore, the random positioning ensures that dirt accumulation is always, or at least very frequently, varied, since different, especially random, positions can be used for the protective position, which can be particularly susceptible to dirt ingress. This minimizes the ingress of dirt into the loading flap mechanism or at least reliably prevents the accumulation of a particularly high local concentration of dirt.This prevents, for example, the charging flap from jamming due to dirt. Furthermore, the particularly low level of soiling also significantly reduces wear on the charging flap mechanism.
[0016] In a further embodiment, the position control device is designed as an electronic computing device. This means that the protective position can be determined as a random position by means of the position control device or the electronic computing device, whereby at least one control signal can be transmitted to the drive device by means of the electronic computing device, in particular depending on the specific intermediate position or the specific random position, whereby the loading flap can be pivoted or moved about the pivot axis into the specific protective position or specific random position by means of the drive device, in particular depending on the transmitted control signal.In other words, it is intended that the electronic computing device can be used to determine the target position, and that at least one control signal can be transmitted to the drive unit by means of the electronic computing device, particularly depending on the determined target position, in order to pivot the loading flap into the determined target position by means of the drive unit, that is, to change the actual position of the loading flap according to the determined target position. This allows the random position to be determined in a particularly cost-effective manner, thereby enabling the loading flap to be pivoted into the random protective position in a particularly cost-effective manner. This allows wear reduction to be achieved in a particularly cost-effective manner.
[0017] In a further embodiment, it is provided that the random position, intermediate position, or protective position is a position to be randomly selected from several predetermined or predefined positions. This means that, by means of the position control device, a position can be determined, specifically by means of the position control device, as the protective position, specifically a position to be randomly selected from several predetermined or predefined positions. In other words, the random position is a selection, particularly a random one, from a predetermined range of values.Thus, by means of the position control device, one of the predefined positions, stored, for example, in the electronic computing device, particularly in a memory, can be selected, particularly randomly, and thereby determined as the protective position into which the loading flap can subsequently be pivoted about the pivot axis. In this way, the intermediate position is not permanently stored in the memory of the electronic computing device, which is also referred to as the memory area. Instead, the random number generator can be implemented in an algorithm executed on the electronic computing device, thereby generating a random absolute position within the defined value range as the protective position.Position information generated in this way can then be sent to the drive unit, also known as the loading flap actuator, particularly when the weather protection position is to be reached. The drive unit can then initiate a movement of the loading flap into this weather protection position. This ensures that the random position is not left to "pure chance" but is a random selection, meaning that all potentially possible weather protection positions can be particularly well-suited for weather protection.
[0018] In a further embodiment, it is provided that the loading flap, for pivoting from the closed to the open position, is to be pivoted upwards around the pivot axis in the vehicle's vertical direction, particularly when the loading flap device is installed in the vehicle. In other words, at least a portion of the loading flap is positioned lower in the vehicle's vertical direction when closed than when open. Thus, the loading flap is a vertically opening and closing flap. Therefore, the approach to the weather protection position using the random generator can be achieved in a particularly wear-friendly manner with a vertically opening loading flap system.
[0019] In a further embodiment, it is provided that, in the protective position, the charging element connected to the connection device, particularly electrically, is at least partially, and in particular predominantly or completely, preferably upwards in the vehicle direction, covered by the charging flap. In other words, in the protective position, the charging element connected to the connection device is at least partially, and in particular predominantly or completely, covered by the charging flap when the charging element is connected to the connection device, preferably directly, and in particular when the electrical energy storage device is supplied with electrical energy via the charging element and the connection device. This allows the connection device and / or the charging element to be particularly well protected against weather influences.
[0020] A second aspect of the invention relates to a charging device for a motor vehicle, wherein the charging device comprises at least one charging flap device according to the first aspect of the invention. Advantages and advantageous embodiments of the first aspect of the invention are to be regarded as advantages and advantageous embodiments of the second aspect of the invention, and vice versa. A third aspect of the invention relates to a motor vehicle, in particular an electrically powered one, which comprises at least one charging device according to the second aspect of the invention. Thus, the motor vehicle comprises, in particular, the charging flap device according to the first aspect of the invention. Advantages and advantageous embodiments of the first and second aspects of the invention are to be regarded as advantages and advantageous embodiments of the third aspect of the invention, and vice versa.
[0021] A fourth aspect of the invention relates to an arrangement of a loading flap device, particularly according to the first aspect of the invention, on a component of a motor vehicle, particularly according to the third aspect of the invention. Advantages and advantageous embodiments of the first, second, and third aspects of the invention are to be regarded as advantages and advantageous embodiments of the fourth aspect of the invention, and vice versa.
[0022] The charging flap device comprises a charging flap and a fastening device by which the charging flap is pivotably held on the vehicle component about a pivot axis between a closed position and at least one open position, which is in particular different from the closed position. Furthermore, the charging flap device comprises at least one drive device by means of which the charging flap can be driven or is driven to pivot about the pivot axis, for example, between the closed position and the open position. In the closed position, a connection device provided or designed for charging an electrical energy storage device of the vehicle is covered by the charging flap, in particular completely, and in the open position, the connection device is at least partially or completely exposed by the charging flap.
[0023] To minimize wear on the loading flap device, at least one position control device coupled to the drive unit is provided, by means of which a protective position, distinct from the open and closed positions and representing an intermediate position relative to the open and closed positions, into which the loading flap is to pivot, can be determined or is determined as a random position, wherein the loading flap can be pivoted or is pivoted into the determined protective position about the pivot axis by means of the drive unit. A fifth aspect of the invention relates to a method for operating a loading flap device, particularly according to the first aspect of the invention, for a motor vehicle, and particularly according to the third aspect of the invention.Advantages and advantageous embodiments of the first, second, third and fourth aspects of the invention are to be regarded as advantages and advantageous embodiments of the fifth aspect of the invention and vice versa.
[0024] The charging flap device comprises a charging flap and a fastening device by which the charging flap is pivotably held on a component of the motor vehicle about a pivot axis between a closed position and at least one open position. The charging flap is driven by at least one drive device, in particular electrically, whereby the charging flap is pivoted, for example, by means of the drive device, between the open position and the closed position, in particular automatically. In the closed position, a charging port for an electrical energy storage device of the motor vehicle is covered by the charging flap, and in the open position, the charging port is exposed by the charging flap.
[0025] In order to keep wear on the loading flap device particularly low, according to the invention a protective position, which is an intermediate position with respect to the closed position and the open position, into which the loading flap is to be pivoted, is determined as a random position by means of a position control device coupled with the drive device, wherein the loading flap is pivoted about the pivot axis into the determined protective position by means of the drive device.
[0026] Further features of the invention will become apparent from the claims, the figures, and the description of the figures. The features and combinations of features mentioned above in the description, as well as the features or combinations of features mentioned below in the description of the figures and / or shown in the figures alone, are not only usable in the combinations specified, but also in other combinations or on their own.
[0027] The invention will now be explained in more detail with reference to a preferred embodiment and the drawing. Figure 1 shows a schematic front view of a charging device according to the invention for a motor vehicle; and
[0028] Fig. 2 shows a schematic side view of a charging device according to the invention for a motor vehicle; and
[0029] Fig. 3 shows a schematic side view of a charging device according to the invention for a motor vehicle, wherein a charging plug is connected to a connection device of the charging device.
[0030] In the figures, compare or functionally equivalent elements and assign them the same reference symbol.
[0031] Fig. 1 shows a schematic front view of a loading device 1 for a motor vehicle. Preferably, the motor vehicle, particularly in its fully manufactured state, includes the loading device. The loading device 1 has a loading flap assembly 2. Thus, Fig. 1 shows, in particular, a schematic front view of an arrangement of the loading flap assembly 2 on a component 3 of the motor vehicle. The component 3 is, in this case, a component of the loading device 1, for example, a loading hopper 4, which can also be referred to as a loading recess. Fig. 2 shows a schematic side view of the loading device 1 or the arrangement.
[0032] The charging device 1 has a connection device 5 for charging an electrical energy storage device of the motor vehicle, which is designed separately from the charging flap device 2. The connection device 5 can be understood to be, in particular, a charging port. In this case, the connection device 5 is designed for connection, in particular electrical connection, with a charging element 6, which is designed separately from the charging device 1, and in particular from the motor vehicle. This charging element 6 is, for example, a charging plug, in particular a charging plug comprising a charging cable. The charging element 6 can be plugged into the connection device 5 for electrical charging of the electrical energy storage device and is thereby electrically connected to the connection device 5.The charging element 6 is, for example, part of an external energy supply device related to the motor vehicle, such as a charging station, a wallbox, or the like. For electrical connection of the charging element 6 to the connection device 5, a connecting part 7, for example a plug, of the charging element 6 can be inserted into the connection device 5. In this case, the charging element 6 has a charging cable which can be connected, for example, to an electrical energy source of the energy supply device, in particular electrically. The charging element 6 is illustrated in Fig. 3, which shows a schematic side view of the charging device 1 or the arrangement and the charging element 6.
[0033] The loading flap device 2 comprises a loading flap 9 and a fastening device 10, which is formed separately from the loading flap 9, by means of which the loading flap 9 is pivotably held or pivoted on the component 3, for example directly, between a closed position and at least one open position 11 about a pivot axis 12. The fastening device 10 is, for example, designed as a hinge arm or, for example, has at least the hinge arm. Furthermore, the loading device 1, in particular the loading flap device 2, comprises a drive device 13 by means of which the loading flap 9 can be driven or is driven to pivot, for example, between the closed position and the open position 11, about the pivot axis 12. The drive device 13 can be referred to as an actuator. For example, the drive device 13 is designed as an electric machine. In Fig. 1 and in Fig.In Fig. 2, the charging flap device 2 is in the open position 11. The closed position is illustrated in Fig. 2 by means of a dashed line 14. In the closed position, the connection device 5 can be covered by the charging flap 9, or in particular completely, by the charging flap 9. As shown in Fig. 1, the component 3 at least partially, and in particular completely, limits an opening 3a in which the connection device 5 is arranged. In the closed position, this opening 3a is closed by means of the charging flap 9, in particular completely. Therefore, the charging element 6, in particular the connecting part 7, cannot be connected or coupled to the connection device 5 in the closed position, which in turn makes charging the electrical energy storage device impossible, in particular in the closed position.This means that in the closed position, the charging element 6 is not connected to the connection device 5, and thus the electrical energy storage device is not charged. In the open position 11, the connection device 5, or rather the opening 3a, can be released, in particular at least partially or completely, by the charging flap 9. Thus, in the open position 11, the opening 3a is not closed by the charging flap 9. In the open position 11, the charging element 6 can be connected to the connection device 5, in particular electrically, via the connecting part 7, in order to charge the electrical energy storage device. Thus, the electrical energy storage device can be charged in the open position 11.
[0034] To minimize wear on the loading device 1, in particular the loading flap assembly 2, the loading device 1, in particular the loading flap assembly 2, has a position control device 15 coupled to the drive unit 13. This device allows a protective position 16, which is an intermediate position between the closed and open positions 11, into which the loading flap 9 is to pivot, to be determined or randomly selected. Furthermore, it is provided that the loading flap 9 can be pivoted or is pivoted by means of the drive unit 13 about the pivot axis 12 into the protective position 16, which is determined in particular as previously specified.This allows the pivoting of the loading flap 9, for example from the open position 11 to the protective position 16, to occur at least partially stochastically and thus, in particular, with a particularly varied motion. This results in a particularly varied load on the fastening device 10, especially on any movement mechanism effected or effected by the fastening device 10 for pivoting. In this way, one-sided or monotonous wear can be avoided. Thus, the durability of the loading flap device 2 can be significantly increased. In particular, the safety against damage to the loading flap device 2 can be significantly enhanced.
[0035] The term "random position" in this context does not mean, in particular, that the protective position 16 and the pivoting of the loading flap 9 into the protective position 16 are completely arbitrary. Rather, there are specific boundary conditions that limit the random determination of the intermediate position. As already mentioned, the protective position 16 is always an intermediate position relative to the open position 11 and the closed position. This means that in the protective position 16, the loading flap 9 is open less than in the open position 11. Furthermore, in the protective position 16, the loading device 1, in particular the connecting device 5, or the loading element 6 connected to the connecting device 5, is protected, especially from the elements.These boundary conditions ensure that the pivoting into the protective position 16, while somewhat stochastic and therefore particularly varied, can nevertheless be carried out in a feasible manner. In particular, in the protective position 16, the charging element 6 can be connected to the connection device 5, thus enabling the electrical energy storage device to be charged, especially in the protective position 16.
[0036] In this embodiment, it is provided that the position control device
[0037] 15 is configured as an electronic computing device 17. The electronic computing device 17 is configured, for example, as a control unit. This control unit is, for example, a control unit that performs a charging function of the motor vehicle, in particular of the electrical energy storage device, i.e., is responsible for this charging function. Furthermore, the random position or the protective position 16 is a randomly selectable or selected position from several predefined positions.Thus, for example, several potential protective positions 16 are stored in a memory of the electronic computing devices 17, whereby one of these stored protective positions 16 can be selected randomly, i.e. as a random position, by means of the electronic computing device 17, into which the loading flap 9 can be pivoted by means of the drive device 13 about the pivot axis 12, for example from the open position 11, and for example after the loading element 6 has been connected to the connection device 5, into the selected protective position 16.
[0038] For example, the position control device 15, in particular the electronic computing device 17, comprises at least one random number generator. For example, each of the respective protective positions 16 stored in the memory is assigned a number. For example, a random number is determined by means of the random number generator to select the protective position 16. Thus, depending on the determined random number, one of the stored protective positions 16 can be selected, in particular if the determined random number corresponds to the number assigned to the respective stored protective position 16. Thus, the protective position
[0039] The charging device 1 has at least one detection device by which the charging element 6 connected by the connection device 5, and in particular the connection of the charging element 6 to the connection device 5, can be detected or is detected. For example, the detection device is coupled to the position control device 15, whereby the determination of the protective position 16 can be carried out when the charging element 6 is detected or when the connection of the charging element 6 is detected by the position control device 15. Thus, as soon as the charging element 6 is plugged into the vehicle, the electronic computing device 17 can, in particular in the next step, move to a position in the form of the protective position 16 within the specific value range.
[0040] In the protective position 16, the charging element 6 connected to the connecting device 5 can be at least partially, and in particular predominantly or completely, covered by the charging flap 9. This is particularly evident in Fig. 3. In this embodiment, the covering is achieved from above in the upward direction of the vehicle. This provides particularly effective weather protection.
[0041] In this embodiment, the loading flap 9 is pivoted upwards about the pivot axis 12 in the vehicle's vertical direction 18 to move from the closed position to the open position 11. Thus, when pivoting the loading flap 9 from the closed position to the open position 11, the direction of movement has at least one component pointing upwards in the vehicle's vertical direction 18, in particular a vectorial component. Therefore, the loading flap device 2 in this case is a vertically opening loading flap system.
[0042] In this embodiment, a stop element 19 is arranged on the loading flap 9, via which the loading flap 9 strikes the loading element 6 in the event of a collision. This prevents damage to the loading flap 9 and / or the loading element 6 in such a collision. In this instance, the stop element 19 is arranged on the side of the loading flap 9 facing away from the fastening device 10. Reference numeral list
