Description

[0001] The invention relates to a storage compartment device for a passenger car according to the preamble of claim 1. Furthermore, the invention relates to a passenger car with such a storage compartment device.

[0002] DE 10 2023 001 757 B3 discloses a front trunk compartment for an electrically powered motor vehicle, with a housing which defines a trunk volume with a housing wall, wherein at least within a partial area of ​​the housing wall a cavity for a liquid is formed.

[0003] German patent DE 10 2020 106 560 A1 discloses a vehicle with a front-end structure that includes a front-mounted trunk and a pivoting front hood mounted above the trunk. The trunk is a support formed in the shape of a trunk recess, the support being made of a plastic material with a plastic film on its surface. Due to the heat-insulating properties of the support, the trunk recess is passively cooled.

[0004] Furthermore, DE 20 2016 000 950 U1 discloses a heat-insulating transport box comprising a container with an opening and a corresponding lid, wherein the container is at least partially made of foam plastic. It is proposed that the container and the lid be manufactured from foam plastic, in particular from expanded polypropylene (EPP). This material is cost-effective and relatively easy to process, and in addition to good thermal insulation due to gas inclusions, it also exhibits advantageous structural properties.

[0005] Finally, US patent 2004 / 0135390 A1 shows a vehicle load management system in which a storage compartment is provided under a trunk floor cover, which is used as a cooler by means of a temperature-insulating layer.

[0006] The object of the present invention is to create a storage compartment device for a passenger car and a passenger car, such that a temperature in a front storage compartment of the passenger car can be kept particularly low.

[0007] This problem is solved according to the invention by a storage compartment device for a passenger car with the features of claim 1 and by a passenger car with the features of claim 10. Advantageous embodiments with expedient further developments of the invention are specified in the remaining claims.

[0008] A first aspect of the invention relates to a storage compartment device for a passenger car, in particular for a front storage compartment of the passenger car. Preferably, the passenger car, especially in its fully manufactured state, has the storage compartment device, and in particular the front storage compartment.

[0009] The passenger car is, for example, designed as an electrically powered passenger car. In other words, the passenger car is, for example, designed as a battery-electric vehicle or as a hybrid vehicle.

[0010] The storage device comprises at least one storage element having at least one outer wall and at least one inner wall. In other words, the storage element includes at least the outer wall and the inner wall. The storage element, in particular the inner wall, at least partially, and in particular predominantly or completely, defines the front storage space of the passenger car. In other words, the front storage space is at least partially, and in particular predominantly or completely, formed by the storage element, in particular by the inner wall.

[0011] The front storage compartment is commonly referred to as the frunk. The word "frunk" is a portmanteau of the English words "front" and "trunk." The front storage compartment is thus located in or at the front of the passenger vehicle. The front section, particularly in relation to the vehicle's longitudinal direction, can be understood as the front part of the vehicle. This front section can also be referred to as the front of the vehicle.

[0012] The storage element can be designed, at least in its essential form, as a trough. Thus, the front storage space, for example, is designed as a storage tray, which can be specifically referred to as a frunk tray. In particular, the storage element can be a rigid, for example, self-supporting solid body.

[0013] The front storage compartment preferably has at least one opening through which, for example, the storage compartment itself, considered on its own, opens into or onto its surroundings. Thus, for example, an item to be transported, such as a bag or suitcase, can be moved through the opening and thereby into the storage compartment, where it can be arranged, and in particular, stowed. Furthermore, it is possible to move the item arranged in the storage compartment through the opening and thereby out of the storage compartment, i.e., to remove it from the storage compartment or to move it onto or into its surroundings. The opening is preferably formed by the storage compartment element, i.e., in particular, directly bounded by it.

[0014] The passenger car preferably also has a front hood, which can be referred to as a front flap or engine hood. The front hood is preferably movable between at least one closed position that closes the opening and at least one open position that releases at least a portion of the opening, and in particular pivotable about at least one pivot axis. This means that, preferably in the closed position, the front hood closes the opening and thus the storage compartment, so that, for example, objects located in the storage compartment cannot unintentionally fall out of the storage compartment through the opening while the passenger car is driving.In the open position, the front hood preferably releases at least the partial area of ​​the opening, so that, for example, the aforementioned object can be moved through the partial area in the open position and thus placed in or removed from the storage space.

[0015] In particular, the passenger car has a structure, also referred to as a body, preferably designed as a self-supporting body, which forms the interior of the passenger car, also referred to as the passenger compartment or passenger space. During the aforementioned journey of the passenger car, persons, such as the driver, may be present in this interior. For example, the hood is movable, in particular pivotable, and attached to the structure so that it can be moved relative to the structure between the closed and / or open positions, in particular pivoted about at least one pivot axis. It may be provided that the storage compartment element is attached to the structure, at least indirectly, in particular directly, or is an integral part of the structure.

[0016] To maintain a particularly low temperature in the front storage compartment, the storage compartment element has at least one thermal insulation element, separate from both the outer and inner walls, which is arranged between the outer and inner walls. This thermal insulation element provides thermal insulation to the storage unit and / or the front storage compartment. In other words, the thermal insulation element extends at least partially, and in particular predominantly or completely, between the outer and inner walls. This means that the thermal insulation element is located within the storage unit, specifically within the storage compartment element itself; that is, it is integrated into the storage unit, and in particular into the storage compartment element.The thermal insulation element significantly reduces heat flow from the environment through the storage unit into the front storage compartment, meaning it is considerably lower than if the storage unit did not have the thermal insulation element. In other words, the heat flow from the environment into the front storage compartment is routed through the thermal insulation element, thus providing thermal insulation to the front storage compartment, particularly against the environment.

[0017] The invention is based in particular on the following findings and considerations: In a conventional passenger car, for example, a radiator is located near the front storage compartment, whereby the front storage compartment or the storage compartment device is exposed to the radiator, and in particular to the heat emitted by the radiator. For example, the radiator blows hot, and in particular very hot, air, especially directly, onto the storage compartment device or the front storage compartment. Furthermore, during fast charging, a front area in the longitudinal direction of the vehicle, in which the front storage compartment is located, can become particularly hot. Fast charging can be understood in particular as the particularly rapid charging of an electrical energy storage device of the passenger car. Furthermore, there are, for example, some challenges regarding excessive noise, especially concerning noise pollution, emanating from this front area.NHV is an abbreviation which means "Noise Vibration Harshness" in English.

[0018] The storage device according to the invention overcomes the aforementioned disadvantages. The thermal insulation element prevents, for example, the inner wall from heating up excessively, thus keeping the front storage space, and in particular the at least one item stored therein, particularly cool. This means that the temperature in the front storage space, and especially the temperature of the at least one item stored therein, can be kept particularly low. It prevents the temperature in the front storage space from heating up excessively, for example to 76°C, thereby reliably preventing, for example, a person (also referred to as a customer) from burning their fingers if some metal parts are stored in the front storage space.In other words, burns to the fingers caused by contact with hot metal objects, such as those stored in the front storage compartment, can be particularly reliably prevented. This means that safety against such burns can be significantly increased. The invention thus provides a solution to reliably prevent overheating of the front storage compartment, and especially overheating of the objects stored therein. The objects stored in the front storage compartment, which can also be referred to as internal items, can also help to cool the compartment. Furthermore, the storage compartment design allows for more weight to be placed in the front area, thereby solving or significantly improving the aforementioned problem of excessive noise (NVH).Overall, it is evident that a concept for preventing frunk overheating can be created.

[0019] The thermal insulation element preferably extends continuously, i.e. without interruption, between the outer wall and the inner wall.

[0020] To minimize heat transfer from the surroundings via the storage unit into the front storage compartment, a further embodiment provides for the outer and inner walls to be constructed separately. This allows the temperature of the front storage compartment to be kept particularly low. Furthermore, the storage unit can be manufactured with minimal effort.

[0021] To enable particularly cost-effective production of the storage unit, the outer and inner walls are welded together, especially directly, in a further embodiment. This means that the outer and inner walls are or will be joined by welding. Furthermore, welding significantly increases the mechanical strength of the storage unit.

[0022] To achieve particularly effective thermal insulation of the front storage compartment, the thermal insulation element is designed as a solid. In other words, the thermal insulation element is a solid. This means that the thermal insulation element is in a solid state, especially when installed in the storage compartment of the passenger vehicle and / or during operation of the passenger vehicle. Therefore, the thermal insulation element is not a fluid. This significantly reduces heat transfer from the surroundings through the storage compartment into the front storage space.

[0023] To provide particularly good thermal insulation for the front storage compartment, the thermal insulation element is, in a further embodiment, made at least partially, predominantly, or entirely of cotton wool and / or cork. In other words, one of the materials used in the thermal insulation element is cotton wool and / or cork.

[0024] To achieve particularly good thermal insulation of the front storage compartment, a further embodiment provides for at least one gap between the outer and inner walls, which is filled at least predominantly, and in particular completely, by the thermal insulation element. In other words, the gap between the outer and inner walls is arranged in such a way that it is filled at least predominantly, and in particular completely, with the thermal insulation element. The term "at least predominantly" here refers to more than 50%, preferably more than 75% or more than 90%, and in particular 95%. The gap is, for example, any space extending between the outer and inner walls. This means that the thermal insulation element fills, for example, any space between the outer and inner walls.

[0025] In a further embodiment, the outer wall is formed from at least one first material, and the inner wall is formed from at least one second material different from the first. In other words, the outer and inner walls are made of different materials. This allows heat transfer from the environment via the outer wall to the inner wall, and thus to the storage space at the front, to be kept particularly low. The outer and inner walls can therefore be thermally insulated from each other very effectively.

[0026] To achieve particularly good thermal insulation of the front storage compartment, the first material in this design has a lower thermal conductivity than the second material. In other words, the outer wall has a lower thermal conductivity than the inner wall. This allows the inner wall to be thermally insulated from the outer wall, thus minimizing heat transfer from the environment to the inner wall via the outer wall. This, in turn, keeps the temperature of the inner wall particularly low, thus keeping the temperature of the front storage compartment especially low.

[0027] To achieve particularly good thermal insulation of the front storage compartment, the inner wall is made of plastic. In other words, the second material is plastic. The plastic allows, for example, the temperature of the inner wall to be kept particularly low. Furthermore, the plastic allows the front storage compartment to be lined or covered. Additionally, the weight of the storage unit or front storage compartment can be kept very low. Finally, the manufacturing costs for the storage unit or front storage compartment can be significantly reduced.

[0028] A second aspect of the invention relates to a passenger car which has at least one storage compartment according to the first aspect of the invention. In particular, the passenger car has a front storage compartment. 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.

[0029] Further advantages, features, and details of the invention will become apparent from the following description of a preferred embodiment and from the drawings. The features and combinations of features mentioned above in the description, as well as those mentioned below in the figure description and / or shown in the figures alone, can be used not only in the combinations specified, but also in other combinations or individually, without departing from the scope of the invention.

[0030] This shows: Fig. 1 a schematic partial sectional view of a passenger car according to the invention; and Fig. 2 another schematic partial sectional view of a passenger car according to the invention.

[0031] In the figures, identical or functionally equivalent elements are provided with the same reference symbols.

[0032] Fig. Figure 1 shows a schematic partial sectional view of a passenger car 10, which has a front storage compartment 12, located in the front area of ​​the passenger car 10. The front storage compartment 12 can also be referred to as a "frunk". In this case, the front storage compartment 12 is formed by a storage device 14 of the passenger car 10. Thus, the passenger car 10 has the storage device 14.

[0033] The storage unit 14 is in Fig. Figure 2 shows a further schematic partial sectional view of the passenger car 10. The storage compartment device 14 has at least one storage compartment element 16, which has at least one outer wall 18 and at least one inner wall 20, which is formed separately from the outer wall 18. The storage compartment element 16, and in particular at least the inner wall 20, at least partially, and in particular predominantly or completely, limits the front storage compartment 12. For example, the storage compartment element 16, and in particular the inner wall 20, limits the front storage compartment 12, for example, in the longitudinal direction 24 of the vehicle, in particular forwards and / or backwards, and / or in the vertical direction 26, in particular downwards, and / or in the transverse direction 28 of the passenger car 10.The storage element 16 can be understood in particular as a storage housing for the front storage space 12. For example, the storage element 16 is designed in a trough shape, that is, as a storage trough.

[0034] The front storage compartment 12 is designed for storing at least one object, for example, luggage. For this purpose, the front storage compartment 12, in particular at least its inner wall 20, has, for example, at least one loading platform 30 on which the object, in particular the luggage, can be arranged or is arranged, in order to store the object 32, in particular the luggage, in the front storage compartment 12. The loading platform 30 is thus formed, for example, at least partially, in particular predominantly or completely, by the storage element 16, in particular by the inner wall 20.

[0035] In particular, the outer wall 18 is positioned further outwards than the inner wall 20 with respect to the front storage compartment 12, for example in the longitudinal direction 24, the vertical direction 26, and / or the transverse direction 28 of the vehicle. In other words, the inner wall 20, particularly in the vertical direction 26, the longitudinal direction 24, and / or the transverse direction 28, is covered or lined by the outer wall 18, especially towards the outside. The outer wall 18 and the inner wall 20 are preferably formed separately from each other. The outer wall 18 is, for example, designed as an outer shell, and the inner wall 20 is, for example, designed as an inner shell. Thus, the storage compartment element 16 has, for example, at least two shells in the form of the aforementioned outer shell and the inner shell. For example, the storage compartment element 16 consists of these two shells.

[0036] The passenger car 10, in particular the front storage compartment 12, has, for example, an opening 34 which, for example, points upwards in the vehicle's vertical direction 26 26. Furthermore, the passenger car 10 preferably has a front hood 36 which is movable or is movable between a closed position 40 that closes the opening 34, i.e., the front storage compartment 12, and at least one open position that releases at least a partial area 38 of the opening 34. Fig. 1 and Fig. 2 In the present case, the front hood 36 is in the closed position 40. In particular, in the closed position 40, the opening 34 is, in particular completely, covered by the front hood 36. In the open position, the closing or covering of at least part 38 of the opening 34 is omitted.

[0037] As in Fig. 1 and in Fig. As shown in Figure 2, the passenger car 10 has, for example, at least one sealing element 42 which, in this case, surrounds the opening 34 at least partially, and in particular predominantly or completely. The sealing element 42 is, for example, arranged, and in particular attached, to the storage compartment element 16, and in particular attached to it. The sealing element 42 is, for example, part of the storage compartment device 14. For example, in the closed position 40, the front hood 36 rests, in particular directly, against the sealing element 42, whereby, for example, the front storage compartment 12 is sealed fluid-tight, in particular liquid-tight, and / or gas-tight in the closed position 40. In the open position, the front hood 36 preferably does not rest against the sealing element 42, whereby, in particular, the front hood 36 is at least partially, and in particular predominantly or completely, separated from the sealing element 42 in the open position.

[0038] For example, the passenger car 10 has at least one locking device 44 by means of which, in the closed position 40, the hood 36 is secured against movement, in particular unintentional movement, especially pivoting, from the closed position 40, for example into the open position. The locking device 44 has, for example, at least one locking bar.

[0039] In the exemplary embodiment, the passenger car 10 has at least one cooling device 46, which can also simply be referred to as a radiator. In this case, the cooling device 46 is arranged in the front area of ​​the passenger car 10, in particular in the longitudinal direction 24 in front of the front storage compartment 12. Preferably, at least one component of the passenger car 10 can be cooled by means of the cooling device 46. For example, the cooling device 46 is designed as a heat exchanger, whereby heat can be dissipated from the cooling device 46, for example into an environment 48 of the passenger car 10, particularly for cooling the aforementioned component. For example, the cooling device 46 is arranged near the front storage compartment 12 or the storage compartment device 14, whereby heat can be transferred from the cooling device 46 to the storage compartment device 14. This is in Fig. 1 illustrated by means of arrows 50. Thus, for example, the storage device 14, in particular the storage element 16, for example at least the outer wall 18, is thermally exposed to the cooling device 46, in particular to its emitted heat, whereby the storage device 14, in particular the storage element 16, can be heated by the cooling device 46, in particular unintentionally.

[0040] In order to keep the temperature of the front storage compartment 12, and in particular the temperature of the object 32 arranged or stored in the front storage compartment 12, especially low, the storage compartment device 14 has at least one thermal insulation element 52, which is separate from the outer wall 18 and the inner wall 20 and which is arranged, for example, in the longitudinal direction 24 of the vehicle, in the vertical direction 26 and / or in the transverse direction 28 of the vehicle, between the outer wall 18 and the inner wall 20, whereby, for example, the front storage compartment 12 is thermally insulated from the cooling device 46 by means of the thermal insulation element 52. In particular, the inner wall 20 is thermally insulated from the outer wall 18 by means of the thermal insulation element 52.By means of the thermal insulation element 52, heat transfer from the surroundings of the storage device 14, in particular from the cooling device 46, via the storage device 14 into the front storage space 12, and thus in particular into the object 32, can be significantly reduced, and in particular avoided. This allows the object 32 to be kept particularly cool. This means that the object 32 can remain particularly cool, especially while it is stored in the front storage space 12.

[0041] Preferably, the thermal insulation element 52 is designed as a solid body 54. This solid body 54 is, for example, cotton wool and / or cork. Thus, the thermal insulation element 52 is, for example, at least partially, and in particular at least predominantly or completely, made of cotton wool and / or cork. Accordingly, materials with poor thermal conductivity, such as cork, cotton wool, or the like, are located between the two aforementioned layers.

[0042] As in Fig.As shown in Figure 2, a space 55 extends between the outer wall 18 and the inner wall 20, which is preferably at least predominantly, and in particular at least substantially completely, filled by the thermal insulation element 52, especially the solid body 54. Thus, for example, the storage compartment element 16, in particular the inner wall 20 and the outer wall 18, is lined at least predominantly, and in particular completely, by means of the thermal insulation element 52. In particular, the thermal insulation element 52 is arranged, and in particular attached, preferably directly to the outer wall 18 and / or to the inner wall 20. For example, the thermal insulation element 52 covers the inner wall 20 in the longitudinal direction 24 of the vehicle, in the vertical direction 26 of the vehicle, and / or in the transverse direction 28, in particular at least predominantly or completely.Thus, for example, the inner wall 20 is thermally insulated over a large area, in particular over a large area, preferably at least predominantly, in particular completely, against the outer wall 18 by means of the thermal insulation element 52.

[0043] The storage element 16 thus has, for example, several layers. A first of these layers is the outer wall 18. A second of these layers is the inner wall 20. A third of these layers is an intermediate layer, which is arranged between the outer wall 18 and the inner wall 20. In this case, this intermediate layer is the thermal insulation element 52. Thus, for example, the storage device 14, in particular the storage element 16, has at least one layered structure comprising the aforementioned layers.

[0044] The gap 55 is preferably the only gap 55 between the inner wall 20 and the outer wall 18, meaning that, for example, no further gaps 55 are provided between the outer wall 18 and the inner wall 20. This allows the storage element 16 to be, for example, completely filled or lined with the thermal insulation element 52.

[0045] For example, the thermal insulation element 52 surrounds the front storage space 12 and / or the inner wall 20 in the circumferential direction of the front storage space 12, in particular without interruption, at least predominantly, in particular completely.

[0046] The outer wall 18 is formed, for example, from a first material 56. The inner wall 20 is formed, for example, from a second material 58 that differs from the first material 56. The first material 56 preferably has a lower thermal conductivity than the second material 58. The outer shell, also referred to as the outer casing, can therefore be formed from a material with lower thermal conductivity than the inner shell. In particular, the outer shell can consist of the material with lower thermal conductivity, especially in the form of the first material. The inner wall 20 is formed, for example, from plastic. Thus, the second material 58 can be the plastic. In particular, the inner shell can therefore be made of the plastic, and especially consist of the plastic.

[0047] For example, the outer wall 18 and the inner wall 20 are or will be welded together, in particular directly, that is, preferably bypassing or avoiding the thermal insulation element 52. This means that, for example, the two shells mentioned are joined together by welding.
