Description

The invention relates to a battery arrangement for a hybrid motor vehicle, in particular a partially electrified hybrid motor vehicle, wherein the vehicle battery is or can be arranged below a seat surface of a vehicle seat and above the vehicle floor, according to the preamble of claim 1.

A widely used variant of a hybrid motor vehicle is the so-called partially electrified or mild hybrid. In so-called partially electrified hybrid vehicles (called “mild hybrid” or “mHEV”), an electric motor is also used, but its torque and battery power are not sufficient to drive the vehicle alone. The electric drive only supports the combustion engine to increase performance. The partially electrified hybrid still has good fuel-saving potential and can also be integrated into existing vehicle concepts with little effort, whereas more development effort is required for full hybrids. The vehicle battery for such partially electrified hybrids is typically designed as a 48-volt battery.

The storage space in such a hybrid motor vehicle for the 48-volt battery, which is safe and at the same time practical, is limited. Studies have shown that there is a suitable place for the vehicle battery under the driver's seat. Typically, however, this entails further restrictions because there is then no longer any space below the driver's seat for the servomotors that enable the driver's seat to be adjusted automatically. The arrangement of the vehicle battery under the driver's seat therefore typically restricts the adjustability of the driver's seat to mechanical devices.

An important aspect of motor vehicles is the safety for the occupants in the event of an accident, which is largely determined by the design and effectiveness of the existing deformation zone or crumple zone. An effective crumple zone not only serves to protect the occupants from direct mechanical impact, but also to protect the vehicle electronics and, in the case of a hybrid vehicle, in particular to protect the vehicle battery. The safety of the driver and the vehicle battery in the area of the driver's seat is typically checked with the side impact test. A side collision is simulated in which the vehicle is thrown sideways against rigid objects such as trees or stakes or moving objects such as other vehicles.

A desired deformation of the body should minimize the effects on the driver and the vehicle battery underneath. With this desired deformation, the vehicle floor bends down below the driver's seat. If the vehicle battery were to rest on the vehicle floor, it would also sink or be pulled down, which increases the risk of deformation or damage to the vehicle battery. Furthermore, to protect the driver, stiffened cross members are provided in a transverse direction of the vehicle in the area of the driver's seat and the vehicle floor.

Various solutions for protecting the driver and / or the vehicle battery in the event of a collision with the vehicle are proposed in the prior art.

The JP 2014-88068 A discloses a battery arrangement in which a vehicle battery is arranged in an elevated position below the driver's seat, so that the battery is protected from liquid, for example spilled beverages. As a result, a waterproof battery housing can be dispensed with, which means that the production costs for the vehicle battery can be reduced. For this purpose, the lower side of the vehicle battery rests flat on a holding section of a holding device, which can be designed with a U-shaped cross section as a bent sheet metal or cast from hard plastic. The leg ends of the U-shape hang as a fastening section for fastening to an underside of the vehicle seat or to the seat rails. The vibrations and shocks while driving are absorbed by cushioning material, which is arranged between the holding section and the battery housing.

The DE 10 2010 045 997 A1 discloses a battery arrangement in which a vehicle battery is trapezoidal, that is to say with lateral bevels, arranged in the center tunnel of the vehicle. A beveled reinforcement is provided on the top of the vehicle battery, whereby the vehicle battery, together with the reinforcement, is adapted to the geometry in the interior in the center tunnel. Supported in this way from the inside, in the event of a side impact, the center tunnel forms a support or an abutment against a cross member of the vehicle seat, which has a predetermined breaking point. The crossmember bends upwards through the predetermined breaking point and lifts or pushes the seat frame of the vehicle seat over the center tunnel.

According to the US 2014/0136863 A1 three battery modules of a battery unit are placed under the driver's seat, with the battery modules resting on a support plate. The battery unit is also connected to a longitudinal strut of the vehicle body by means of lateral fastening flanges. Above the vehicle battery is a bracket-like Support device for the driver's seat provided, which is screwed on the front and rear of the vehicle battery, with respect to the vehicle direction, on cross struts of the vehicle body.

In the US 8,556,016 B2 A vehicle battery is arranged lying on the vehicle floor in an intermediate space which is delimited on the top by the driver's seat, to the front with respect to the direction of travel by a cross strut and to the rear by an elevation of the vehicle floor. The fuel tank is located in the rear elevation. Alternatively, the vehicle battery rests in a recess in the vehicle floor.

In view of the state of the art shown, securing the vehicle battery in the event of a vehicle collision therefore still offers room for improvement. Rigid boxes or struts can protect the vehicle battery from direct mechanical impact, but at the same time reduce the effectiveness of the deformation zone, which has a negative effect on the safety of the vehicle occupants. Nevertheless, the deformation process must not risk damaging the vehicle battery.

The invention is based on the object of protecting the vehicle battery of a hybrid motor vehicle and at the same time optimizing the deformation zone of the motor vehicle in order to improve occupant safety, in particular in the event of a side impact.

According to the invention, the object is achieved by a battery arrangement for a hybrid motor vehicle, in particular for a partially electrified hybrid motor vehicle, wherein the vehicle battery is or can be arranged below the vehicle seat and above the vehicle floor, with the features of claim 1. Further, particularly advantageous embodiments of the invention are disclosed in the dependent subclaims.

It should be pointed out that the features and measures listed individually in the following description can be combined with one another in any technically meaningful manner and show further embodiments of the invention. The description additionally characterizes and specifies the invention, particularly in connection with the figures. The terms “above” and “below” or “on top” and “below” are to be understood in relation to an operating position of the vehicle. “Vehicle longitudinal direction” or X-direction means a substantially horizontal direction along the vehicle longitudinal axis. “Transverse direction of the vehicle” or Y-direction is to be understood as an essentially horizontal direction transverse to the longitudinal axis of the vehicle. A “vehicle vertical” or Z-direction means a direction essentially perpendicular to the ground. The invention preferably relates to the driver's seat, but according to the invention the vehicle battery can also be arranged below any other vehicle seat in the vehicle. When the term vehicle battery is usually referred to in a simplified manner, it is always to be understood as a battery unit consisting of at least one battery housing and battery modules, battery cells or other battery sub-units arranged therein.

The invention relates to a battery arrangement for fastening a vehicle battery below a seat surface of a vehicle seat and above a vehicle floor of a hybrid motor vehicle, in particular a partially electrified hybrid motor vehicle, the battery arrangement having a vehicle battery and a battery cage at least partially surrounding the vehicle battery, and the vehicle battery by means of a guide arrangement along a transverse direction of the vehicle is attached to the vehicle seat such that it can slide relative to the battery cage and / or to the vehicle seat.

Due to the mobility of the vehicle battery along a transverse direction of the vehicle, kinetic energy can be dissipated in the event of a side impact of the hybrid vehicle against a tree or another obstacle without the vehicle battery being deformed or damaged. The center tunnel of the vehicle body or the area around the center tunnel is available for such a compensating movement of the vehicle battery. The vehicle battery can therefore be moved in the event of a side impact through the slidingly movable fastening or suspension of the vehicle battery to the center tunnel, that is to say in a positive Y direction of the vehicle. As an alternative or in addition, the vehicle battery can be attached so that it can be moved in the opposite negative Y direction of the vehicle, that is to say away from the center tunnel. As a result, the battery can perform a compensating movement even if the vehicle crashes on the opposite side of the vehicle.

In an optional advantageous further development, the vehicle battery can be displaced along a transverse direction of the vehicle, in particular towards a center tunnel, by a distance that essentially corresponds to a distance between the vehicle battery and the center tunnel.

On the one hand, the vehicle battery can be mounted within the battery cage so as to be movable relative to the battery cage. In addition, the battery cage can be moved relative to the vehicle seat or the motor vehicle, so that the distance of the Displacement of the vehicle battery as the sum of the displacement of the battery cage and the vehicle battery relative to the battery cage results.

In a preferred embodiment of the battery arrangement, the battery cage or protective cage or protective battery cage is designed or has an impact protection for protecting the vehicle battery in a stop area in the event of a side impact of the hybrid motor vehicle.

In the event of a side impact of the hybrid motor vehicle, this side impulse can transmit a shock to a side wall of the vehicle battery or the battery cage, for example due to the movement of the door sill. On the side wall of the vehicle battery facing the door sill, the battery cage is therefore designed with an impact protection or as an impact protection. The impact protection prevents damage to the vehicle battery or the battery housing. Due to the local restriction of the impact protection to the points that are actually exposed to mechanical stress in the event of a side impact, the battery cage does not have to completely surround the entire vehicle battery. Areas that do not experience any stress in the event of an impact do not have to be continuously developed. In addition to the impact area, the corners and edges in particular must be additionally protected. Depending on the vehicle type, the protection area can also be enlarged. By limiting it to locally endangered areas, material can be saved and the additional weight required for the vehicle can be minimized.

In particular, the guide arrangement can advantageously be designed between the vehicle battery and the battery cage for a relative movement between the vehicle battery and the battery cage.

In the event of a side impact against the battery cage, it is deformed, but remains essentially stationary. At the same time, the battery cage releases the vehicle battery for movement along the transverse direction of the vehicle towards the center tunnel. As a result, the vehicle battery gains additional distance compared to the area that is subject to severe deformation. Damage to the battery housing itself and the vehicle battery located therein can thus be avoided.

The guide arrangement preferably has at least one guide groove or guide rail formed on the vehicle battery and at least one tab on the battery cage that is designed to be complementary thereto for a sliding engagement in the guide groove or guide rail.

Such a guide arrangement can be manufactured particularly easily. In the event of a side impact, the tab or some other projection on the battery cage slides into engagement with the guide groove and / or the guide rail. Both the tab and the guide groove are aligned parallel to the vehicle transverse direction in order to enable the sliding movement in said direction. In addition, the guide arrangement can have a locking device or a safety device to prevent unintentional displacement.

In an optional development, the battery cage is arranged on a holding device, the holding device being able to be connected in a stationary manner to the vehicle seat.

Preferably, the holding device is or can be connected to the cross members of the vehicle seat and / or the seat rails of the vehicle seat. In order to keep the effects of a side impact away from the occupant of the vehicle seat, the cross members and the seat rails themselves or are designed to be stiffened in one position with respect to one another. For this purpose, the holding device for the battery cage to be fixed in place is particularly preferably connected to these vehicle components.

The vehicle battery is preferably held suspended above the vehicle floor by means of the battery cage.

“Hanging” means, among other things, that the vehicle battery is either arranged at a distance from the vehicle floor or is in direct or indirect contact with it. The fastening arrangement is thus quasi a hanging device. By means of such a hanging device, the vehicle battery is not only secured against slipping, but rather the total weight of the vehicle battery is borne completely or essentially completely by the fastening device designed as a hanging device. Suspension devices are typically characterized by the fact that they have a certain amount of movement in the event of vibration or other shocks in order to compensate for the vibration. This prevents the vibration or other shocks from being transmitted, for example while driving over cobblestones, which means that additional padding of the vehicle battery or around the vehicle battery is unnecessary and complexity is reduced. The battery is attached so as to be movable.

In a particularly preferred embodiment of the invention, the holding device has two first sections for connection to the battery cage and two second sections for connection with a first or front cross member and with a second or rear cross member.

Furthermore, the vehicle battery is preferably held on two opposite side walls and / or on an upper side and / or on a lower side by fastening the holding device to a connecting section. The first cross member is preferably designed to be additionally stiffened with respect to the second cross member. In an optional development of the invention, the holding device has two first sections for connecting to the vehicle battery and two second sections for connecting to a first cross support of the first cross member and / or a second cross support of the second cross member. The transverse support is also to be understood as the upper boundary wall of the transverse beam. During assembly, the second connecting section can simply be placed on the cross support of the cross member and then fixed with all known fastening means used in vehicle construction. This enables a particularly simple and quick assembly of the battery arrangement. The connection area located between the first section and the second section is elongated, preferably designed as a resilient connecting strand or as a resilient connecting sheet and runs on the top or on an upper side of the vehicle battery.

Furthermore, for improved safety of the vehicle battery, the vehicle battery can be provided by means of a deflecting bevel attached on the top or in an upper region of the vehicle battery.

In particular, it is provided that a housing surrounding the vehicle battery has this deflecting bevel. The deflecting bevel can prevent damage to the vehicle battery or the battery housing from hitting or impacting or knocking a seat rail adjacent to the vehicle battery. Instead of hitting a side wall of the battery housing, the seat rail would slide along the deflecting slope over the vehicle battery or the battery housing. In the event of a side impact with the vehicle (e.g. barrier, pole, other vehicle ...), corresponding kinetic energy can be transferred to the seat rails of the vehicle seat, whereupon the seat rails move in the direction of the center tunnel in the area of the vehicle's longitudinal axis. If necessary, transverse reinforcements are provided between the two seat rails adjacent to the vehicle battery, which keep the seat rails at a fixed distance from one another. In this case, both rails move at a fixed distance and relative to the vehicle battery. However, due to the deflecting bevel in the area of the seat rail, no stop is formed which could, for example, lead to deformation or damage to the battery housing. Instead, the kinetic energy dissipates because the seat rail slides along the deflection slope above or on the top of the battery housing of the vehicle battery and the structure of the vehicle can use the space gained for additional deformation or reduction of kinetic energy through structural deformation without damaging the battery. The vehicle battery and the seat rail move or nest in one another, also due to the sliding movement of the vehicle battery in the battery cage. The integration of the deflecting bevel in the battery housing means that no additional components are required, which saves vehicle weight and reduces the complexity of parts.

In the different figures, the same parts are always provided with the same reference numerals, which is why they are usually only described once. In particular, the figures are to be understood to the effect that various components are masked out or shown in a simplified manner for better clarity.

The front view of the 1 Figure 11 shows a battery assembly 100 , which is a vehicle battery 200 and a vehicle seat 300 having. The effect of a side vehicle impact is shown 500 , i.e. an impact in a transverse direction of the vehicle, on the vehicle battery 200 that is between the vehicle floor 350a , 350b and the vehicle seat 300 is arranged, according to the prior art. The undeformed vehicle floor is shown in dashed lines 350a on which the position of the vehicle battery 200a before impact 500 is shown in dashed lines. In the event of a side impact 500 becomes the vehicle body 400 (see. 2 ) and thus also the vehicle floor 350b deformed, on which the vehicle battery 200 rests on or is attached to this. The vehicle floor 350b bends downwards, which also affects the vehicle battery 200 a downward movement in a direction of movement shown with an arrow 120 carries out. The vehicle battery 200 is due to its own weight and / or due to the attachment to the sagging vehicle floor 350b pulled down. This carries the risk that the vehicle battery 200 or the housing surrounding it is deformed or otherwise damaged.

2 however, shows a battery arrangement according to the invention 100 for fastening the vehicle battery 200 with the vehicle body 400 , the vehicle seat 300 (see. 1 ) is hidden. The vehicle battery 200 is arranged in a battery housing, which in turn is supported by a battery cage 160 is surrounded in partial areas. This applies particularly to the sub-areas that occur in the event of a vehicle impact 500 (see. 1 ) from mechanical effects of the deforming vehicle body 400 are affected. Therefore, a side wall of the vehicle battery facing the rocker has 200 an impact protection 161 on, whereby not the entire side wall of the impact protection 161 is covered, but only the edge areas of the side wall. Essentially is the battery cage 160 as edge protection 162 for the side edges of the vehicle battery 200 educated. In addition to the side edges facing the sill, there are in particular those on the underside 230 (see. 3 ) the side edges of the vehicle battery to protect against a deforming vehicle floor 350b (see. 1 ) with edge protection 162 Mistake. The battery cage 160 has a fastening portion 163 for connection to the holding device 111 on. The holding device 111 has two first sections 111a on that in two places with the mounting section 163 of the battery cage 160 are firmly connected. The holding device 111 also has two second sections 111b at one point each with the first or front cross member 390 and the second or rear cross member 380 are firmly connected. The vehicle battery 200 is through the holding device 111 , and in the battery cage 160 , hanging between the first cross member 390 and the second cross member 380 held. The holding device 111 is with a one-piece connecting plate 112 formed, which in a central area on the top 210 the vehicle battery 200 flat and on the side of the vehicle battery 200 is bent, so that two second sections, preferably designed as flat end sections 111b flat on the first or front cross support 391 and the second or rear cross support 381 rest. The holding device is in the operational mode of the hybrid motor vehicle 111 stationary with the battery cage 160 and the vehicle body 400 connected. On the other hand is between the vehicle battery 200 and the battery cage 160 a guide arrangement 110 provided, the functioning of which is explained in more detail below.

3 shows a side view of the battery arrangement according to the invention 100 . The guide arrangement 110 consists of at least one guide groove 113 on an outer wall in the battery housing. The guide groove 113 is along the vehicle transverse direction for movement of the vehicle battery 200 aligned in a vehicle transverse direction. In this guide groove 113 one engages as a protrusion on the battery cage 160 formed tab 114 a. So that is the vehicle battery 200 for a movement in a + Y direction 164, i.e. to the center tunnel 420 of the vehicle and in a - Y-direction 165, that is, in a direction towards the rocker panel, mounted so as to be slidable. In normal operation of the motor vehicle, it is not mandatory that the vehicle battery 200 in the guide arrangement 110 moved back and forth. Therefore, for example. Securing devices between the guide groove 113 and the tab 114 be provided which allows movement between the vehicle battery 200 and the battery cage 160 prevented in the event of simple vibrations while driving. For a sliding movement of the vehicle battery 200 to the center tunnel 420 (see. 2 ) towards the center tunnel 420 facing side of the vehicle battery 200 with a bevel 250 provided so that, for example, a rigid seat rail does not come against the vehicle battery 200 hits, but slides over the battery housing. It should be noted that the guide arrangement 110 not just on the side of the vehicle battery 200 but also at the top 210 and / or bottom 230 can be arranged.

4a shows the battery arrangement 100 and the center tunnel 420 in a static starting position 430 before a side impact 500 (see. 4b) of the vehicle in which the vehicle battery 200 is placed in a position defined by the cross member 380 , 390 (see. 2 ) and the holding device 111 is determined. The vehicle battery 200 is possibly at a short distance above a non-deformed vehicle floor 350a arranged without burdening it. By the starting position 430 remains a distance 431 to the center tunnel 420 so that this distance 420 for a deformation space for a movement of the vehicle battery 200 in a + Y direction 164 in the event of a side impact 500 of the vehicle is available. The stop area 220 the vehicle battery 200 is for an impact, e.g. of the door sill through an impact protection 161 of the battery cage 160 specially secured.

4b shows the battery arrangement 100 and the center tunnel 420 in an end position 440 after a side impact 500 of the vehicle with the vehicle battery 200 opposite the battery cage 160 has moved dynamically. Finds out the vehicle battery 200 a load due to the load path due to the lateral intrusion of the vehicle in the vehicle transverse direction (Y direction) slides the vehicle battery 200 inside the battery cage 160 in a + Y direction 164. The shift takes place in a controlled manner, so that the individual components shift into one another and utilize free deformation space without in particular the battery housing of the vehicle battery 200 undergoes additional mechanical action. This can reduce the risk of deformation of the vehicle battery case 200 be reduced. In a preferred embodiment of the invention, the one with the battery cage 160 connected holding device 111 , especially the connecting plate 112 , deformable in a predetermined manner. In addition, the vehicle battery slides 200 in the battery cage 160 by the amount of the relative displacement shown in dashed lines 441 . In particular, the second sections are not shown 111b with the cross members 380 , 390 connected, with one or both of the cross members 380 , 390 (see. 2 ) can be made stiffened. The connecting plate 112 itself, however, is upon movement of the battery cage 160 deformable, in particular elastically deformable In cooperation with the impact protection 161 and the edge protection 162 of the battery case 200 through the battery cage 160 can damage the vehicle battery 200 in the event of a side impact 500 be kept low.
