DETAILED DESCRIPTION OF THE DRAWINGS
[0025] In FIGS. 1 and 2, a front chamber 10 is depicted in the region of a motor vehicle nose of a passenger vehicle. In the present case, the passenger vehicle is designed as a fully electrically driven passenger vehicle (BEV) or as a hybrid vehicle (PHEV). Thus, in the front chamber 10 of the passenger vehicle, space for a cargo hold 12 is correspondingly present, which is delimited on the side of the outer periphery and downwards by a trough-shaped cargo hold box 14 arranged immovably/stationarily in this exemplary embodiment. The cargo hold box 14 has a loading opening upwards, is presently formed at least substantially rectangularly in the clear cross-section and comprises respective walls 16, 18, 20, 22 running peripherally on the side of the outer periphery and extending at least substantially in the vertical direction of the vehicle, and a base 24. On its upper edge region 29, the cargo hold box 14 is provided with an outwardly offset peripheral frame 26, which has an end face side 28 facing towards a front bonnet 30. That is to say, the offset that is similar to a flange when seen in cross-section through the cargo hold box 14 on its upper edge region 29 has the end face side 29, the surface normal of which runs in principle, i.e., even when it encloses an angle of more than 0° and less than 180° with the vertical axis of the vehicle (z-axis), in the vertical direction of the vehicle.
[0026] The front chamber 10 can be closed by the front bonnet 30 arranged in its closed position in FIG. 1, which can be shifted from this closed position, for example in a rear end region, into an open position by means of corresponding mounting elements, in which the front bonnet 30 is positioned with a front end upwards. In FIG. 2, the front bonnet 30 has been left out for the sake of clarity.
[0027] FIG. 3 shows a schematic sectional view of the cargo hold arrangement according to FIGS. 1 and 2 along a longitudinal plane of the motor vehicle running in the longitudinal direction of the vehicle (x-axis) or in the vertical direction of the vehicle (z-axis). A cover 32 emerges from FIG. 3, by means of which the cargo hold box 14 is closed in the closed position of the front bonnet 30. The cover 32 of the or for the cargo hold box 14 is here arranged below the front bonnet 30 in the closed position and, in the exemplary embodiment depicted here, is fixed on an underside of the front bonnet 30 via respective brackets 34. When the front bonnet 30 is shifted between its closed position shown in FIGS. 1 and 3 and an open position, the cover 32 is accordingly also able to be shifted between its closed position shown in FIGS. 1 and 3 and an open position. After opening the front bonnet 30, the cargo hold 12 of the cargo hold box 14 is thus directly accessible, that is to say for a person standing in front of the motor vehicle, since the cover 32 is also automatically in its open position.
[0028] Furthermore, it can also be seen from FIG. 3 that the cover 32 has an upper cover wall, which runs substantially in parallel to the underside of the front bonnet 30. A collar 40 protruding downwards in the vertical direction of the vehicle is formed peripherally around the cover wall on the side of the outer periphery, such that the cover is overall formed to be substantially box-shaped or trough-shaped.
[0029] Here, a substantial feature of the present cargo hold arrangement is that the cover 32 is formed to be smaller or to bounce back in relation to a clear cross-section of the cargo hold box 14, here substantially rectangular, and the collar 40 either already projects into the interior chamber of the cargo hold box in its closed position or, in the event of a reshaping of the front bonnet caused by an impact with a pedestrian and, accordingly, a corresponding shifting of the cover 32 in the direction of the base 24 of the cargo hold box 14 can quasi immerse/extend, whereby this can be moved into the cargo hold 12 of the cargo hold box 14 with a shift of the cover 32, caused by an accident, downwardly in the vertical direction of the vehicle, as is shown in FIG. 4 in a sectional view substantially analogous to FIG. 3. Accordingly, the cargo hold box 14 is formed to be larger in terms of cross-section than the cover 32 at least in an upper region in relation to a horizontal plane running in the longitudinal direction of the vehicle in the transverse direction of the vehicle, such that a gap s emerges at least substantially peripherally between the collar 40 of the cover 32 and the respective wall 16, 18, 20, 22 of the cargo hold box 14.
[0030] Furthermore, it can be seen from FIG. 3 that a seal is presently provided between the collar 40 of the cover 32 and the cargo hold box 14, such that the cargo hold box 14 is tightly sealed in the closed position of the cover 32. In the present case, its seal 42 running peripherally around on the collar 40 on the peripheral side is sealed both off from the upper end face side 28 of the cargo hold box 14 and to the respective wall 16, 18, 20, 22 of the cargo hold box 14 oriented in the vertical direction of the vehicle by means of respective sealing lips 44 or 46 and 48. It is clear that the seal 42 can optionally also only be carried out in relation to the end face side 28 or in relation to the walls 16, 18, 20 22 of the cargo hold box 14. Additionally, it is clear that the sealing lips 44, 46, 48 are formed correspondingly resiliently, such that the cover 32 can be moved downwards in the vertical direction of the vehicle in the event of an impact with a head impact of a head 50, schematically indicated in FIG. 4, of a pedestrian as a result of a frontal accident with them. It should be noted that at least the sealing lips 44 to 48 are formed to be resiliently elastic and, with a front bonnet arranged in the closed position and, accordingly, the cover 32 in the closed position, they are automatically sealingly applied to the corresponding wall 16 to 22 or the end face side 28 due to the restoring forces caused by the material.
[0031] Furthermore, it can be seen from FIG. 3 that a clearance for spacing is provided between the cover wall and the front bonnet 30, such that in the event of a pedestrian impact onto or on the front bonnet 30 in the covering region with the cargo hold box 14, the front bonnet 30 can additionally be deformed without it directly and immediately coming into contact with the upper wall of the cover. In combination with the shifting of the cover 32 into the cargo hold 12 of the cargo hold box 14, this resilience of the front bonnet 30 thus provides for a corresponding mitigation of the consequences of an impact of a pedestrian with their head 50 on the front bonnet 30 as a result of a frontal collision with the motor vehicle.
[0032] In a sectional view in each case, FIGS. 5 and 6 in turn show the cargo hold arrangement according to FIGS. 1 and 2 along a sectional plane running in the vertical direction of the vehicle or in the longitudinal direction of the vehicle. In particular, here the cargo hold box 14 and a concrete exemplary embodiment of the cover 32 and a further exemplary embodiment of the seal 42, which, in the present case, also seals with a sealing lip 52 to the upper end face side 29 and with a bead-shaped sealing portion 54 to the walls 16, 18, 20, 22 of the cargo hold box 14, can once again be seen. Here, FIG. 6 shows in which way the cover 32 with the seal 42 can be shifted into the cargo hold 12 of the cargo hold box 14. Here, the sealing portion 54 slides along the respective wall 16 to 22 of the cargo hold box 14 in the direction of the base 24. The sealing lip 52 here remains in continuous contact with the cargo hold box 14 and slides adjacently to thus via the rounded transition region between the end face side 28 and the walls 16 to 22.
[0033] Furthermore, it can be seen from FIGS. 5 and 6 that a lower part 56 of the front bonnet 30 has a recess or elevation 58, which is adjusted to the shape of the cover 32 or vice versa, i.e., the shape of the cover 32 is adjusted to the indentation on the inside of the front bonnet 30.
[0034] It is clear that, in the event of the cover 32 being shifted into the cargo hold 12 of the cargo hold box 14 due to an accident, a corresponding clearance must be provided in its upper region, into which the cover 32 can be moved. This clearance can preferably be kept free of goods.
[0035] It is also to be seen as included in the scope of the invention that the cover 32 does not necessarily have to be fixedly held on the underside of the front bonnet 30. A bracket on the underside of the front bonnet 30 in the sense of a mount would also be conceivable. This could be necessary, for example, if the front bonnet 30 has to be shifted in a more laborious movement mechanism between the closed position and the open position, which makes it necessary for the cover 32 to also carry out a more complicated movement.
