Definitions
- the invention relates to an energy storage housing arrangement for a motor vehicle, comprising an energy storage housing and an underrun protection attached to the underside of the energy storage housing.
- the invention also relates to an underrun protection for an energy storage housing arrangement and a motor vehicle.
- Underride guards are typically monolithic or one-piece components, in particular made of metal or plastic, whereby in electric or hybrid vehicles these are often attached to an energy storage housing of an underfloor battery.
- Underrun contactors serve to protect energy stores or HV modules accommodated in the energy store housing, in particular with regard to any mechanical loads in the event of accidents or the like.
- energy storage devices in the motor vehicle pose a high risk of fire in the event of damage, which is why they should be protected from mechanical loads and damage that may result from this.
- Underride guards are also used in motor vehicles in order to prevent that in the event of a collision with another traffic participant, in particular with another motor vehicle or a pedestrian, the latter gets under the motor vehicle.
- Underride guards are therefore used to avoid potentially serious injuries to the other road user and / or damage to the motor vehicle.
- the object on which the invention is based can be seen in specifying an improved concept for an underrun protection, in particular with regard to an improvement in the mechanical properties.
- the underrun protection comprises a sandwich arrangement with an upper cover plate on its upper side facing the Energy Grandege housing and a lower cover plate on its underside, with between the upper cover plate and the lower deck plate a filler is arranged and the top of the Sandwichanord voltage is profiled via webs or ribs.
- the energy storage housing typically has a base plate or a housing bottom, to which, preferably four, side walls of the energy storage housing are connected, which are typically perpendicular to the base plate and can be attached to the base plate via screws or other suitable fastening means.
- the energy storage housing is preferably closed via a housing cover which, like the base plate, is preferably screwed to the side walls.
- energy storage or accumulators are added, which are used to store the to drive the, in particular designed as an electric or hybrid vehicle, motor vehicle.
- the underrun protection is designed in at least three layers, the filler being provided between the upper cover plate and the lower cover plate, which preferably limit the underrun protection towards the outside.
- the webs or ribs represent, as it were, reinforced elongated areas of the underrun protection, which ultimately increases the flexural strength of the underrun protection. This optimization of the topology of the underrun protection or the energy storage housing arrangement results in improved energy absorption in the event of sudden load cases, in particular in crash situations or accidents.
- the webs or ribs can be implemented by a corresponding geometric shape of the upper cover plate, it being possible for this shape and the geometric shape of the filler to be adapted to one another.
- the upper cover plate at least in sections, for example, have elongated or channel-like bulges which face the energy storage housing or, more precisely, the base plate of the energy storage housing and which form the webs or ribs.
- the lower cover plate is preferably flat in order to optimize the aerodynamic properties of the energy storage housing arrangement or of the associated motor vehicle, in particular in order to reduce the c value.
- the upper cover plate is particularly preferably provided as a one-piece workpiece, also with regard to the webs or ribs. Furthermore, the sandwich arrangement comprising the upper cover plate, the filler and the lower cover plate can be provided as a component that does not come from a tool, that is, this component can be produced in a single step using appropriately shaped tools.
- the underrun protection in the area of the webs or ribs is attached to at least one reinforcement element arranged within the energy storage housing and intended to increase the mechanical stability of the energy storage housing and / or on at least one side wall of the energy storage housing.
- the topology of the energy storage housing and that of the underrun protection can therefore be adapted to one another in such a way that the underrun protection is better supported on the support structure of the energy storage housing.
- the at least one reinforcement element can be a carrier of the energy storage housing that runs at least in sections along the base plate of the energy storage housing, in particular extending between two opposite side walls of the energy storage housing.
- the support which can be a longitudinal and / or transverse support, for example, serves to increase the strength of the energy storage housing and thus protect the energy storage devices accommodated in the housing from mechanical loads and damage resulting from this in the event of a crash or accident.
- the carrier preferably extends over the entire height of the energy storage housing, that is to say from the base plate to the housing cover, and is attached to it. Furthermore, the carrier preferably extends completely between two opposite side walls of the energy storage housing and is optionally also attached to these.
- the carrier can have a rectangular cross section with a solid or hollow profile. Furthermore, the carrier can be made of metal, in particular of steel or aluminum, alternatively also of plastic or other suitable materials.
- a plurality of carriers is preferably provided which form rectangular or cuboid receiving areas for the energy storage devices received in the energy storage housing.
- Each web or each rib can be attached to a respectively different carrier of the energy storage housing.
- the longitudinal axes of the webs or ribs preferably run essentially parallel to the longitudinal axes of the supports when these are attached to one another.
- the carrier can have bores with corresponding threads, in which the screws engage in the fastened state.
- the underrun protection can therefore ultimately be attached to the Trä only by means of the screws, sockets and / or rivets.
- the lower cover plate can have countersunk holes for receiving the heads of the screws and / or rivets.
- the underrun protection and the energy storage housing at least one cooling device which is in thermal contact with at least one energy storage device accommodated in the energy storage housing, including in particular at least one cooling plate, is arranged.
- the energy stores generate heat that has to be dissipated, in particular during charging or ferry operation of the motor vehicle.
- the cooling device can be in thermal contact with the base plate of the energy storage housing, the base plate typically being made of metal and thus having good thermal conductivity, the base plate in turn being able to be in thermal contact with the energy storage device.
- the underrun protection of the energy storage housing arrangement according to the invention also protects the cooling device, as well as the energy storage, from damage in the event of a crash, especially since leakage of the possibly environmentally harmful cooling fluid should be avoided.
- the cooling device can be arranged at a distance from the underrun protection or the upper cover plate of the underrun protection, an air cushion preferably being formed as thermal insulation between these components. This has the effect, particularly at high outside temperatures, that the cooling power provided by the cooling device is not unnecessarily released to the outside via the underrun protection.
- screw connections or the like can be provided for fastening the cooling plates to the energy storage housing.
- the distance between the cooling plates and the sandwich arrangement can be equally constant if the sandwich arrangement between the webs or ribs each has a constant height.
- the sandwich arrangement is designed to be curved in the areas between two webs or ribs, that is to say has a bridge-like structure in a sectional view.
- the cooling device in particular the at least one cooling plate, is preferably part of a cooling circuit or cooling system in which a cooling fluid circulates.
- the cooling device can be connected to cooling lines carrying the cooling fluid, wherein the underrun protection can have corresponding recesses for the passage of the cooling lines.
- the cooling lines preferably run parallel to the underrun protection or the sandwich arrangement.
- the sandwich arrangement can alswei sen at least two webs or ribs, wherein the cooling device is net angeord between two webs or ribs and extends at least over half, preferably over two thirds, of the distance between the webs or ribs.
- the free installation space that is already present between two webs or ribs is used extremely efficiently.
- the cooling device or the cooling plates should be in thermal contact with the largest possible area of the energy storage housing in order to ensure the most efficient possible heat flow between the energy storage and the cooling device.
- a cooling device can be arranged before given between two adjacent webs or ribs.
- the filler is a thermal insulation material, in particular a filler foam.
- the filler not only makes a contribution to the improvement of the mechanical properties of the energy storage housing arrangement already explained, but also serves in a synergetic manner to ensure that specific further measures which cause a thermal decoupling between the energy storage housing and the underrun protection are omitted.
- insulation means or components are no longer required in this embodiment. This is particularly advantageous at comparatively high outside temperatures, in which a heat transfer from the outside via the underrun protection to the energy storage housing should be kept as low as possible.
- the filling material can for example be a plastic, in particular a polyethylene terephthalate (PET), a polyurethane (PUR) or a polymethacrylamide (PMI) or the like.
- PET polyethylene terephthalate
- PUR polyurethane
- PMI polymethacrylamide
- the filler can be a molded component or it can be in the form of sheets.
- the sheet goods can be provided with a local overpressing, which was impressed by the tool used for the filling position of the filler, whereby, for example, recesses of the filler for the screw heads of the cooling plates or the like are realized.
- the upper cover plate and / or the lower cover plate can be made of a plastic and / or fiber-reinforced.
- plastics In contrast to, for example, metallic materials, plastics have a lower density, as a result of which a lighter construction of the energy storage housing arrangement can be realized.
- the energy storage housing arrangement can be mechanically reinforced by the fiber reinforcement.
- Plastics can be provided as materials for the upper cover plate and / or the lower cover plate.
- thermoplastic plastics are used for this purpose, an injection molding process, flint spraying of thermoplastic sheet metal (organic sheets or the like) or extrusion of long-fiber reinforced thermoplastics can be provided as the manufacturing process.
- the upper cover plate and / or the lower cover plate can also be made of a thermosetting plastic, the production method here being wet pressing, an injection method. Ren, pultrusion or extrusion of an SMC (Sheet Molding Compound) can be provided.
- SMC Sheet Molding Compound
- the fibers can for example be glass fibers, carbon fibers or natural fibers.
- the fibers can be seen as flat textile products, in particular scrims, fabrics, nonwovens, or in the form of sheet molding compound molding compounds.
- the fibers can be continuous or discontinuous fibers.
- the cover plates can also be reinforced by flat reinforcement elements, so-called patches. It is also conceivable that at least some of the fibers are aligned unidirectionally.
- the filler is arranged only in the area of the sandwich arrangement adjacent to the energy storage housing between the upper cover plate and the lower cover plate, and otherwise, in particular in an area protruding laterally beyond the energy storage housing, the upper cover plate and the lower one Cover plate are in direct contact with one another or the sandwich arrangement only includes the upper cover plate or the lower cover plate.
- the advantageous effects of the sandwich structure in particular the improved power transmission or the thermal insulation, are mainly required in the contact area of the underrun protection with the battery housing. Outside this area, for economic reasons, in particular to save weight and material, the filler material can be omitted, in which case the upper cover plate is preferably in direct contact with the lower cover plate and these are attached to one another there.
- only the upper cover plate or the lower cover plate can be provided in the area protruding laterally beyond the energy storage housing (that is, in the area that is a continuation of the sandwich level), with the respective other cover plate at the front on the level of the respective cover plate bumps.
- the invention also relates to an underrun protection for an energy storage housing arrangement according to the above description, wherein, based on its state attached to an energy storage housing, the underrun protection comprises a sandwich arrangement with an upper cover plate on its upper side facing the energy storage housing and a lower cover plate on its underside, a filler being arranged between the upper cover plate and the lower cover plate and the upper side the sandwich arrangement is profiled via webs or ribs.
- the filler is a thermal insulation material, in particular a filler foam.
- the upper cover plate and / or the lower cover plate can be made of a plastic and / or fiber-reinforced.
- the filler is only arranged in the area of the sandwich arrangement adjacent to the energy storage housing between the upper cover plate and the lower cover plate, and otherwise, in particular in an area protruding laterally beyond the energy storage housing, the upper cover plate and the lower cover plate are in direct contact with one another or the sandwich arrangement only comprises the upper cover plate or the lower cover plate.
- the invention also relates to a motor vehicle, comprising a Energyspei chergephaseusean extract according to the above description. All the advantages and features relating to the energy storage housing arrangement and the underrun protection can be applied to the underrun protection and vice versa.
- FIG. 1 shows a side view of a motor vehicle according to the invention
- Fig. 2 is a sectional view of an energy storage housing arrangement according to the invention
- FIG 3 shows an exploded view of a sandwich arrangement of an underrun protection according to the invention.
- the motor vehicle 1 shown in Fig. 1 has an energy storage housing arrangement 2, comprising an energy storage housing 3, a plurality of energy storage devices 4 accommodated in the energy storage housing 3 and an underrun protection 5 fastened on the underside of the energy storage housing 3.
- the energy storage 4 accommodated in the interior of the energy storage housing 3 are connected via electrical connection means to a drive motor 22 of the motor vehicle 1 designed as an electric motor.
- the coordinate system shown in Fig. 1 defines the x-axis as the vehicle's longitudinal axis, the y-axis as the vehicle transverse axis and the z-axis as the vehicle's vertical axis.
- Fig. 2 shows a sectional view through the energy storage housing arrangement 2, the cutting plane running in the yz plane.
- the energy storage housing 3 comprises a housing base 6, on which four ten walls 21 extend vertically upwards, that is, in the z-direction.
- the energy storage housing 3 is completed by the housing cover 7, which is screwed to the side walls 21 and several reinforcing elements 9 of the energy storage housing 3, which are designed as carriers 8, for this purpose.
- the carriers 8 are, for example, longitudinal members of the vehicle, i.e. longitudinal members running in the x direction, which extend over the entire height of the energy storage housing 3, i.e. between the housing base 6 and the housing cover 7 and between two opposing side walls 21 of the energy storage housing 3.
- the carriers 8 are screwed to the housing base 6, the underrun protection 5, which will be discussed in detail later, and to the housing cover 7.
- the carrier 8 form a cuboid receiving structure for the energy storage 4, which is in the resulting receptacle rather used during assembly and also screwed to the supports 8.
- the mechanical strength of the energy storage housing 3 is thus ultimately reinforced by the carrier 8.
- the underrun protection 5 has a sandwich arrangement 10 with an upper cover plate 11 and a lower cover plate 12.
- the upper cover plate 11 is on the side facing the energy storage housing 3 or the housing base 6, ie the top, of the underrun protection 5.
- a filler 13 exemplarily designed as a thermal insulation material, in particular a filler foam.
- the upper side of the sandwich arrangement 10 has a profiling formed via webs or ribs 14. The webs or ribs 14 run, in the same way as the carriers 8, for example in the vehicle longitudinal direction, that is to say in the x direction.
- the sandwich arrangement 10 therefore has in the area of the webs or ribs 14 a larger flea in relation to the z-direction than in the remaining area.
- the channel-like geometric structure of the upper cover plate 11 thus realizes the webs or ribs 14 of the sandwich arrangement 10.
- the lower cover plate 12 is designed as a flat plate. An exploded view of the sandwich arrangement 10 is shown in FIG.
- the underrun protection 5 serves to protect the energy storage 4 received in the energy storage housing 3 from mechanical loads and any damage resulting therefrom, in particular in loading cases such as accidents.
- the underrun protection 5 also serves to ensure that in the event of a collision of the motor vehicle 1 with an object, in particular with another motor vehicle, a pedestrian or an animal, the object does not come under the motor vehicle 1, which means that serious injuries can be avoided.
- the underrun protection 5 is not monolithically or in one piece, in particular as a metal sheet, as in previous systems, but instead comprises the sandwich arrangement 10 with the webs or ribs 14, this increases the flexural strength of the underrun protection 5 or the energy storage arrangement 2 causes. This opti- The topology of the underrun protection 5 therefore results in improved energy consumption in the event of sudden load cases, in particular in the event of crashes or accidents.
- the underrun protection 5 is fastened in the region of the webs or ribs 14 to the reinforcing elements 9 formed as carriers 8. Furthermore, the underrun protection 5 is attached to its two lateral webs or ribs 14, not shown in FIG. 2, on the side walls 21 of the energy storage housing 3. The longitudinal axes of the respective webs or ribs 14 run parallel to the longitudinal axes of the associated carrier 8 or side walls 21. This improves the support of the underrun protection 5 on the carriers 8 or the wall structure of the energy storage housing 3.
- the fastening of the underrun protection 5 to the supports 8 is carried out exempla risch by means of several screws 15.
- the screws 15 for this purpose penetrate the sandwich arrangement 10 and are attached to the supports 8.
- the carriers 8, which can be designed as solid or hollow profiles, have for this purpose a plurality of bores, each provided with a thread, into which the corresponding screws 15 engage.
- the sandwich arrangement 10, that is to say the cover plates 11, 12 and the filler 30, and the base plate 6 have corresponding holes or bores for the screws 15.
- the fastening of the underrun protection 5 by means of the lateral webs or ribs 14 on the side walls 21 of the energy storage housing 3 takes place according to the same principle as the fastening of the underrun protection 5 to the supports 8.
- the lower cover plate 12 designed as a flat plate in its central area, has several screw-on points 16 arranged along the webs or ribs 14 or carrier 8, which can be provided as cylindrical or conical countersunk holes or the like, for example, to avoid protrusions of the heads of the screws 15.
- the underrun protection 5 is therefore completely held by the screws 15 on the housing 3 Energy acknowledgedge.
- the motor vehicle 1 also has, by way of example, a cooling system or a cooling circuit in which a cooling fluid circulates, where cooling devices 18 comprising several cooling plates 17 through which the cooling fluid flows are provided.
- cooling devices 18 comprising several cooling plates 17 through which the cooling fluid flows are provided.
- the energy stores 4 heat up, in particular while the motor vehicle 1 is being driven or charged, the heat generated in this case being dissipated by the cooling devices 18.
- the cooling plates 17 are in thermal contact with the, in particular metallic, base plate 6, which in turn is in thermal contact with the energy stores 4.
- the cooling devices 18 comprising several cooling plates 17 are each arranged between two webs or ribs 14 of the sandwich arrangement 10 and extends over as large an area as possible, in particular more than two thirds, of the distance between these two webs or ribs 14 Lines are integrated into the cooling system via the cooling fluid, whereby these lines (not shown) are preferably led out of the sandwich arrangement 10 laterally or downwards, whereby the sandwich arrangement 10 can have corresponding openings or recesses for this purpose through which these lines are led.
- the cooling plates 17 can be fastened to the housing base 6 of the energy storage housing 3 by way of example with further screws (not shown).
- the cooling plates 17 are spaced apart from the sandwich arrangement 10, that is, a thermally insulating layer of air or an air cushion 19 remains between the cooling plates 17 and the sandwich arrangement 10.
- the distance between the cooling plates 17 and the sandwich arrangement 10 is here, since the sandwich arrangement 10 between the Ste gene or ribs 14 each has a constant height, equally constant.
- the sandwich arrangement 10 it is also possible for the sandwich arrangement 10 to be curved, that is to say in the manner of a bridge, in the areas between two webs or ribs 14.
- the filler 13 is explained in more detail below.
- the filler 13 is designed as a filler foam, hence as a thermal insulation material.
- the filler 13 can consist of polyethylene terephthalate, polyurethane or polymethacrylimide. It can ent neither be formed or provided as sheet goods, where appropriate by means of a local overpressing by a tool Ausneh provisions of the filler 13 for z. B. screw heads of the cooling plates 17 or the like can be realized.
- the filler 13 is therefore not only used to increase the mechanical stability of the energy storage housing arrangement 2, but also serves, in addition to the air cushion 19, as a thermal insulation for the energy storage 4 and for the cooling plates 17.
- the upper cover plate 1 1 and the lower cover plate 12 consist of a fiber-reinforced plastic.
- fibers made of glass and / or carbon and / or natural fibers are used here, which are in the form of texti len semi-finished products such as fabrics or the like.
- the filler 13 is only provided in the region of the sandwich arrangement 10 which is adjacent to the energy storage housing 3.
- the upper cover plate 11 is located in the region 20 of the sandwich arrangement 10 protruding laterally beyond the energy storage housing 3 attached directly to the lower cover plate 12.
- the thermally insulating effect of the filler 13 is no longer required in this area, which is why the sandwich arrangement 10 can have a correspondingly simplified structure in its lateral areas 20.
