Description

HOUSING MOUNTING STRUCTURE FOR POWER ELECTRONIC DEVICETECHNICAL FIELD

[0001] The present disclosure relates to a battery housing structure, and more particularly to a mounting member for supporting the battery housing structure.BACKGROUND ART

[0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

[0003] Recently, battery packs or modules are being widely used in vehicles such as hybrid electric vehicles (HEVs) and electric vehicles (EVs). In particular, with the steady exhaustion of carbon energy and increasing interest in the environment, the demand for the hybrid electric vehicles and the electric vehicles is increasing all over the world. In such hybrid electric vehicles or electric vehicles, the most essential component is a battery pack that gives driving power to an automobile motor. Because hybrid electric vehicles or electric vehicles are supplied with power for driving the vehicles through charging / discharging of battery packs, they have higher fuel efficiency and can eliminate or lessen the emission of pollutants, and by this reason, the number of users for driving the hybrid electric vehicle or electric vehicle is now increasing.

[0004] The electrically powered vehicles (i.e. , hybrid electric vehicles or electric vehicles) are typically designed to locate and package battery packs or modules on the vehicle in a manner that protects the battery packs or modules from damage when driving in various climate and environments, and also that protects the battery packs or modules from different types of impacts. Some of these structures are used to control the leak path of the battery housing and also the transmission of the crash energy to the battery compartment. In general, the cross-members of the vehicles include energy absorbing extensions designed to absorb impact loads (e.g., a side impact). Although the variety of structures and components are used to prevent the leak path of the housing and also protect the battery packs or modules during the impact collision, we have discovered that these approaches provide only limited protection. Accordingly, it is desirable that a structure withstands high forces to protect the battery packs or module including other sensitive components, particularly from the impact collisions and also prevents leak path of the housing.SUMMARY OF THE INVENTION

[0005] The present disclosure relates to a mounting member for a housing enclosing a power electronic device such as a battery to secure in a vehicle. According to an exemplary aspect of the present disclosure, the mounting member includes an inner portion coupled to the housing and an outer portion extending outward from the inner portion coupled to the housing. The inner portion includes an internal hole to secure the power electronic device to the housing and an external hole to secure the housing to the vehicle. The outer portion includes at least one mounting hole to secure the housing to the vehicle. The internal hole is open to communicate with an inner side of the housing and the external hole is open to communicate with an outer side of the housing such that the mounting member is configured to prevent a leak path of the housing.

[0006] According to a further aspect of the present disclosure, the inner portion of the mounting member is overmolded into the housing such that the mounting member is integrally combined with the housing. The internal hole and the external hole are each formed with a blind hole and each opening of the internal and external holes is disposed in an opposite side from each other. The inner portion of the mounting member includes a separate area located between the internal hole and the external hole. Further, due to the separate area of the inner portion, the internal hole and the external hole do not communicate with each other such that the inner portion of the mounting member does not allow the leak path through the internal and external holes.

[0007] According to a further aspect of the present disclosure, the internal hole receives a first fastening member passing through a thickness of the power electronic device to fix the power electronic device to the housing. The external hole receives a second fastening member to attach the housing to the vehicle.

[0008] According to a further aspect of the present disclosure, the outer portion of the mounting member includes a first side and a second side formed as an L-shape such that the first side and the second side are substantially perpendicular to each other. The first side of the outer portion is faced to a perimeter wall of the housing and the second side of the outer portion is faced to a floor of the vehicle. The second side of the outer portion includes the mounting hole to receive a third fastening member to attach the housing to the vehicle.

[0009] According to a further aspect of the present disclosure, the mounting member is formed of a metallic material or a thermoplastic material. The mounting member integrally formed with the housing for the power electronic device is used in a hybrid electric vehicle (HEV) or an electro mobility (e-Mobility).

[0010] According to another aspect of the present disclosure, the mounting member includes an inner portion coupled to the housing and an outer portion extending outward from the inner portion. The outer portion includes a plate faced to the floor of the vehicle and formed with at least one mounting hole to attach the housing to the vehicle. The plate of the outer portion has a transition zone configured to direct energy away from the power electronic device enclosed by the housing when a load is transmitted to the mounting member attached to the vehicle during a mis-use of the vehicle.

[0011] According to a further aspect of the present disclosure, the transition zone is defined in a middle portion of the mounting member and located between a stiffness zone defined in the inner portion integrally formed with the housing and a deformation zone defined in the at least one mounting hole attached to a structure of the vehicle. The transition zone of the mounting member is configured to disconnect the stiffness zone including the power electronic device enclosed by the housing from the deformation zone including the structure of the vehicle such that the energy transferred from the load is directed away from the power electronic device. When the vehicle is in the mis-use case such as a shock, or an impact, the deformation zone of the mounting member is configured to absorb the energy transferred from the load.

[0012] According to a further aspect of the present disclosure, the inner portion of the mounting member includes an internal hole to fix the power electronic device to the housing and an external hole to attach the housing to the vehicle.

[0021] The following description is merely exemplary in nature and is in no way intended to limit the present disclosure or its application or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

[0022] FIG. 1 shows a side view of a housing 12 at a mounting location on a vehicle 10 in accordance with an exemplary embodiment of the present disclosure. As shown in FIG. 1 , the power electronic device such as battery packs or modules is enclosed by the housing 12 such that the housing 12 is provided for supporting and protecting the power electronic device for use in the vehicle 10. Recently, the battery packs or modules may be used as a power source for at least one medium- and large-scale device of the power tools: electro mobility (e-mobility) including electric vehicles, hybrid electric vehicles, and plug-in hybrid electric vehicles; electric truck; electric commercial vehicles; and energy storage systems, etc. Further, for using the battery packs or modules in the wide range of applications listed above, the battery packs or modules are generally enclosed by the battery housing 12 to structurally support the battery packs and also to prevent moisture from entering the housing through the life of the electric systems. In addition, the battery packs or modules might be embedded in the coolant flow such that the battery packs are also enclosed by the battery housing 12 to prevent the leakage of the coolant.

[0023] As shown in FIG. 1 , the housing 12 having the power electronic device (i.e., the battery packs or modules) is attached or mounted at or near the vehicle frames (e.g., seat crossmember and / or vehicle floor) or rocker rails (or body sills) of the vehicle 10, so as to locate the contained battery packs or modules generally in a central location on the vehicle10, away from probable impact locations and also in a location that evenly distributes the weight of the batteries and provides the vehicle 10 with a relatively low center of gravity. The battery housing 12 having the battery packs or modules may span below the occupant compartment at a lower portion of the vehicle 10, such as shown in FIG. 1 with a generally thin profile, so as to accommodate various vehicle body types and designs. The battery housing 12 is a substantially rectangular or square shape formed with a battery tray 14 and a battery cover 16. However, in another approach, the battery housing 12 may be formed with other shapes according to the shape of the battery packs or modules or location where the battery housing 12 is placed. Further, it is contemplated that the battery housing 12 may be disengaged or detached from the lower portion of the vehicle 10 for replacing or performing maintenance on the battery packs or related electrical components.

[0024] As shown in FIG. 1 , for example, the battery packs or modules that operate an electric vehicle 10 are generally enclosed in the battery housing 12, which is securely attached to the electric vehicle 10, and the battery packs or modules may be arranged to allow for associated components, such as electrical cables, coolant lines, cold plates, a fire suppression apparatus, or the like, to be arranged and protected within the battery housing 12. To secure and position these items and other conceivable ancillary components (e.g., lighting components, sensors or other vehicle-related accessories) within the battery housing 12, the retention elements are provided and also integrated in the battery housing 12. Moreover, the integrated retention elements serve a dual function of, in addition to retaining or supporting a component, also contributing to the structural performance of the battery housing, such as by functioning as an integrated stiffening feature or load bearing member.

[0025] FIG. 2 shows a perspective view of the housing 12 enclosing the power electronic device 18 (i.e., the battery packs or modules, see FIG. 3). In FIG. 2, the battery tray 14 includes a perimeter wall 15 that extends at least partially around a peripheral portion of the tray base to border a battery containment area. The battery housing 12 as a battery support structure may at least partially support the weight of the battery packs or modules 18 and further provide the structural features or components that offer impact energy management such as to absorb or direct impact force away from or around the battery packs or modules 18 supported in the battery housing 12 having the battery tray 14 and battery cover 16. Generally, the battery tray 14 and cover 16 are each formed of thermoplastic polymer materials such as polyamides, polyolefins, TPU, polyesters, etc. Also, the battery tray 14 and cover 16 formed of multilayer structures of these materials listed above. However, inaccordance with other forms of the present disclosure, the battery tray 14 and cover 16 are each formed of other materials (e.g., bio-based and recycled materials of these materials listed above) to structurally support the battery packs or modules 18.

[0026] In FIG. 2, the battery housing 12 includes a plurality of mounting members 100 coupled to the battery tray 14 along at least one of the perimeter walls 15 to securely locate the battery housing 10 in the vehicle 10 such that the battery housing 12 is securely mounted at the floor 20 of the vehicle 10. In general, as a multi-functional bracket made of a metallic material or a high performance thermoplastic material, the mounting members 100 are each coupled to the battery tray 14 to securely locate the battery housing 12 in the vehicle 10. In particular, each of the mounting members 100 is overmolded into the battery housing 12 such that the battery tray 14 and the mounting members 100 are integrally combined to enclose the battery packs or modules 18 with no leaking issue of the coolant inside the battery housing 12. In accordance with other embodiments of the present disclosure, the battery housing 10 including the battery tray 14, the battery cover 16, and the mounting members 100 as a battery support structure may be formed in multiple configurations with various materials and formation techniques, such as with metal, polymer, or composite components that are formed to provide portions of or the entire battery support structure or with other material configurations or combination thereof.

[0027] In FIG. 2, the battery cover 16 is disposed over the battery tray 14 to cover the battery packs or modules 18 inside the housing 12. For example, the battery cover 16 engages with an upper portion of the battery tray 14 to provide a desired volume for holding the battery packs or modules 18 and associated electrical and cooling components. In addition, the battery cover 16 may include battery bracing elements 22 that are configured to engage the battery packs or modules 18 inside the battery housing 12. For example, the battery bracing elements 22 protrude or extend downward into the battery containment area from the panel portion of the tray cover 16 along a longitudinal (fore and aft) direction X of the vehicle 10 to engage the battery packs or modules 18 at the desired locations inside the housing 12 (not shown). With the tray cover 16 attached over the battery tray 14, the battery bracing elements 22 provide secure engagement of the upper portions of the battery packs or modules 18 relative to the battery tray 14.

[0028] As shown in FIG. 2, the battery housing 12 has a number of mounting members 100, which are each overmolded into the battery tray 14 and arranged to be spaced apart from each other on both sides of the battery tray 14 along the longitudinal direction X of the vehicle 10. However, in another approach, the mounting member 100 may be arranged tobe spaced apart from each other around the whole perimeter of the battery tray 14. The mounting members 100 overmolded into the battery housing 12 are each served as mounting points to the vehicle 10 and coupled to the vehicle structures (e.g., seat crossmember or vehicle floor, etc.) such that due to the mounting members 100, the battery housing 12 having the battery packs or modules 18 is securely located in the vehicle 10.

[0029] FIG. 3 shows a sectional view of the mounting member 100 overmolded into the battery tray 14 having the battery packs or modules 18. In FIG. 3, for example, the mounting member 100 includes an inner portion 102 overmolded into the battery tray 14 and an outer portion 104 extending outward from the perimeter wall 15 of the battery tray 14 in a lateral direction Y. Further, the outer portion 104 of the mounting member 100 is formed with an L- shape bracket having a first side 103 and a second side 105, which is substantially perpendicular to the first side 103. The first side 103 of the outer portion 104 extending from the inner portion 102 in a vertical direction Z of the vehicle is faced to the perimeter wall 15 of the battery tray 14, and the second side 105 (i.e. , a base plate) of the outer portion 104 extending outward from the inner portion 102 in the lateral direction Y is faced to the floor 20 of the vehicle 10. As shown in FIG. 3, the first side 103 is formed with a number of holes (e.g., five holes) to fasten to the perimeter wall 15 of the battery tray 14 and the second side (the base plate) 105 is formed with at least one mounting hole 116 to attach the housing to the floor 20 of the vehicle 10.

[0030] In FIG. 3, the inner portion 102 overmolded into the battery tray 14 includes an internal hole 106, an external hole 108, and a separate area 110 defined between the internal and external holes 106 and 108 such that the internal hole 106 and the external hole 108 are each formed as a blind hole and separated from each other. As shown in FIG. 3, the internal hole 106 and the external hole 108 do not communicate with each other such that the mounting member 100 does not have any leak path through the internal and external holes 106 and 108. Further, because at least the inner portion 102 is overmolded into the battery tray 14 (i.e., the inner portion 102 of the mounting member 100 is integrally combined with the battery tray 14), there is no leak path between the mounting member 100 and the battery housing 14. Accordingly, the mounting member 100 overmolded into the battery housing 12 effectively seals between the inner side and the outer side of the housing such that the leakage of the coolant inside the battery housing 12 and moisture from entering the battery housing 12 are prevented.

[0031] FIG. 3A shows fastening elements, which are each fastened to the internal and external holes 106 and 108, and the at least one mounting hole 116 shown in FIG. 3. In FIG.3A, a first fastening element 112 is fastened to the internal hole 106 of the mounting member 100 by passing through the thickness of the battery packs or modules 18 such that the battery packs or modules 18 are securely attached to the battery housing 12. A second fastening element 114 is also fastened to the external hole 108, which is exposed to the outer bottom surface of the battery tray 14 such that the battery housing 12 is securely mounted at the floor 20 of the vehicle 10. Further, as shown in FIG. 3A, the inner portion 102 of the mounting member 100 has the separate area 110 defined between the internal hole 106 and the external hole 108 such that it prevents any leakage of the coolant through the internal and external holes 106 and 108.

[0032] In FIGS. 3 and 3A, further, the outer portion 104 of the mounting member 100 has the base plate (i.e. the second side) 105 having the mounting hole 116, which is located to be spaced apart from the inner portion 102 in the lateral direction Y of the vehicle 10. The third fastening element 118 is fastened to the vehicle floor 20 through the mounting hole 116 of the base plate 105 such that the battery housing 12 integrally combined with the mounting member 100 is securely attached to the floor 20 of the vehicle 10. Further, the base plate 105 of the mounting member 100 includes a middle portion 120 defined between the at least one mounting hole 116 and the inner portion 102. As shown in FIGS. 3 and 3A, the middle portion 120 of the mounting member 100 is designed to have an integral weak spot such that the middle portion 120 is deformed when any external loads are transmitted to the mounting member 100 during a mis-use of the vehicle 10. Accordingly, the mounting member 100 having the middle portion 120 directs energy transferred by the external loads away from the sensitive elements (i.e., the battery packs or modules 18) in the case of the mis-use such as a side impact, shock, other vehicle collisions, etc., such that the energy is directed to the frame members (e.g., seat crossmember and / or vehicle floor, etc.) of the vehicle 10, which are designed to withstand such loads. The middle portion 120 of the mounting member 100 is configured to disconnect the sensitive components (i.e., battery packs or modules) from being overloaded during the mis-use condition of the vehicle 10 to protect the battery packs or modules 18 enclosed by the housing 12.

[0033] In FIG. 4, when the vehicle 10 has a side collision defined as the mis-use of the vehicle 10, a large impact load F (i.e., an external load) is inputted to a body sill 24 of the vehicle 10. As a result, the side sill 24 plastically deforms while moving to an inner side of the vehicle 10 in the lateral direction Y (i.e., a width direction of the vehicle) and the inputted impact load F is transmitted to the seat crossmember 26 (seat floor), the vehicle floor 20, and also the battery housing 12 (see arrows of FIG. 4). As shown in FIG. 4, the batteryhousing is coupled with a conventional mounting bracket to secure the battery housing in the vehicle, and a side impact load generally transfers some energy to the battery housing, which typically requires a robust mounting bracket to securely attach the battery housing to the vehicle. During the mis-use of the vehicle such as the side collision, the robust mounting bracket may absorb a portion of the inputted load F, which is transmitted directly to the perimeter wall of the battery housing enclosing the battery packs or modules (i.e., the portion of the inputted load is transmitted directly to the battery packs or modules). Due to the inputted load F, accordingly, the battery packs or modules 18 enclosed by the battery housing with the robust mounting bracket could be damaged in case of the mis-use of the vehicle.

[0034] FIG. 5 shows the battery housing 12 integrally combined with the mounting member 100, which is securely attached to the floor 20 of the vehicle 10 according to the present disclosure. As shown in FIG. 5, when the vehicle 10 has a side collision defined as the mis-use of the vehicle, a large impact load F is inputted to the body sill 24 of the vehicle 10. In FIG. 4, the impact load transfers some energy directly to the battery housing 10 by the robust mounting bracket, but as shown in FIG. 5, due to the middle portion 120 of the mounting member 100 defined as the weak spot, the inputted load’s path is changed toward the reinforced vehicle structures such as the seat crossmember 26, the vehicle floor 20, etc. instead of transferring the energy directly to the perimeter wall 15 of the battery housing 12 enclosing the battery packs or modules 18. Accordingly, the middle portion 120 of the mounting member 100 is functioned as a fuse to disconnect the sensitive elements such as the battery packs or modules 18 from being overloaded during the mis-use condition of the vehicle such as impact, shock, side impact, etc. As shown in FIG. 5 of the present disclosure, due to the fuse function of the mounting member 100, the energy transmitted from the inputted load F is directed to the reinforced structures of the vehicle such as the seat crossmember and / or the vehicle floor, which are designed to withstand such loads.

[0035] FIG. 5A shows a detailed view of the mounting member 100 securely attached to the vehicle structure having the floor, side sill, etc. As shown in FIGS. 5 and 5A, when a side collision or any other impact of the vehicle 10 occurs (i.e., the load is inputted to the side sill 24 of the vehicle 10), the inputted impact load F is transmitted toward the reinforced structures of the vehicle such as the seat crossmember and / or the vehicle floor due to the fuse function of the mounting member 100 instead of transmitting directly to the perimeter wall of the housing. Accordingly, the inputted load is efficiently transmitted to the seat crossmember and / or vehicle floor, and the battery packs or modules 18 enclosed by thebattery housing 12 with the mounting member 100 can be protected from the impact load F in the case of the mis-use of the vehicle 10.

[0036] In FIG. 5, the mounting member 100 overmolded into the housing 12 is attached to the vehicle structure and supports the loads between the battery packs or modules 18 and the vehicle structure during the normal use of the vehicle as a connecting member between the battery housing 12 and the vehicle 10. In FIG. 5A, for example, when a side collision of the vehicle occurs, the mounting member 100 attached to the vehicle floor 20 is defined as three different zones such as a stiffness zone 122, a deformation zone 124, and a transition zone 126 between the stiffness zone 122 and the deformation zone 124 along the lateral direction Y of the vehicle 10. The stiffness zone 122 includes an inner portion 102 of the mounting member 100 overmolded into the housing 12 to protect the battery packs or modules 18, and the deformation zone 124 includes the at least one mounting hole 116 of the mounting member 100 attached to the vehicle structure including the vehicle floor and the side sill to absorb the energy transferred by the inputted load F during the mis-use of the vehicle 10. Further, the transition zone 126 includes the middle portion 120 of the mounting member 100, which is defined as a weak spot between the stiffness zone 122 and the deformation zone 124 such that the transition zone 126 is configured to separate the stiffness zone 122 from the deformation zone 124 to protect the battery packs or modules 18 during the mis-use of the vehicle 10 such as a side impact. Accordingly, due to the transition zone 126 of the mounting member 100, the energy transferred by the inputted load F is directed away from the battery packs or modules 18 enclosed by the battery housing 12.

[0037] Further, according to an exemplary embodiment of the present disclosure, the battery housing 12 coupled with the mounting member 100 that directs energy away from the battery packs or modules 18 allows for less metal or highly engineered materials to withstand impact loads during the mis-use of the vehicle, which can lower cost of the components and also weight of the vehicle 10. In addition, the mounting member 100 having the internal and external holes 106 and 108 does not create any leak path through the holes 106 and 108 of the inner portion 102 such that the mounting member 100 does not require any specialized adhesives or seals to be used in the assembly of the battery pack and can save cost in materials and assembly of the battery housing 12. Further, the mounting member 100 formed of a steel material can serve as a grounding path for high voltage batteries enclosed by the battery housing 12 integrally combined with the mounting member100 due to the metal to metal contact between the battery packs 18, the mounting member 100, and vehicle floor 20.

[0038] The mounting member 100 overmolded into the battery housing 12 according to the exemplary embodiment of the present disclosure is suitable to use in the wide range of applications such as the vehicles including electric vehicles and hybrid electric vehicles, etc. Further, in the present disclosure, the mounting member 100 integrally combined with the battery housing 12 may eliminate the need for many fasteners and subsequent sealant / gaskets, which are needed to seal the mounting bracket having thread holes such that it reduces cost and weights of the components and also the battery housing assembly.
