[001] The present subject matter described herein, relates to a vehicle construction and more particularly, relates to a mounting structure of an electromotive vehicle configured to receive a battery and an auxiliary component.
BACKGROUND AND PRIOR ART:
[002] Vehicles include one or more batteries for storing and providing electrical power. These batteries often fail or have reduced performance due to excessive vibrations and shocks generated or transmitted by the vehicles and/or the operating environment. This is especially true for batteries used in vehicles that operate in rough water or uneven terrain. All types of batteries are expensive, difficult to replace, and difficult to safely dispose and recycle.
[003] Conventional battery holders such as battery boxes or trays secure their batteries to the vehicles but often do not absorb vibrations and shocks transmitted or generated by the vehicles and/or the operating environment. Further, various other auxiliary components like CNG controller, or an ECU controller, are also sometimes mounted proximally to the battery trays. Such an attachment results in additional load and bending stresses on the battery trays, and undesirable risk of failure or deformation of conventional battery trays increases under such loading conditions. Further, major weight distribution of the battery and any auxiliary component is on one side of the conventional battery tray, thereby making the battery tray unstable, and excessive bending phenomena is observed in the battery tray and auxiliary component bracket. Further, multiple high stress locations / zones develop on conventional battery tray under the weight of battery and the auxiliary component.
[004] Further, in existing design of the battery tray, plate type of structure is primarily mounted on an engine mount top face to maximize the space utilization in the engine room and to position the battery assembly away from the front end

crash energy absorption region, and the remaining portion of battery tray is mounted on secondary support battery mounting bracket. However, the current structure has several disadvantages, for example, the height of the battery mounting bracket design is governed by the height of engine mount top face. As the engine mount height increases from the vehicle structure, the height of the battery mounting bracket needs to be increased to raise it to the same level of engine mount top face. This results into taller mounting bracket design which deteriorates the battery mounting stability and durability performance.
[005] Further, as the battery tray assembly is directly mounted on engine mount, there is a chance of transferring engine vibrations directly to battery assembly through battery tray. Further, in the existing design, auxiliary components are mounted above the level of the battery tray. This causes excessive bending at the mounting location of the auxiliary component which leads to failure. Therefore, an improved solution is needed to overcome above drawbacks and to increase the overall functionality of battery tray, and the battery tray and auxiliary component mount bracket needs to be designed with increased stiffness to withstand dynamic loads generated during different driving conditions.
[006] Chinese Patent publication CN105667287A provides an ECU (Electronic Control Unit) and storage battery mounting bracket assembly with convenience in mounting and operating for an automobile. The ECU and storage battery mounting bracket assembly comprises an ECU mounting bracket panel (1), a storage battery tray (12) arranged in an engine compartment and a storage battery pressing plate (13) of which two ends are provided with connecting holes; screw holes (4) for mounting an ECU body (10) are formed in the ECU mounting bracket panel (1); the ECU mounting bracket panel (1) is mutually perpendicular to the storage battery tray (12); the lower end of the ECU mounting bracket panel (1) is connected with the right end of the storage battery tray (12); a first connecting screw (15) which is connected with the storage battery tray (12) and upwards extends is arranged in the middle of the left end of the storage battery tray (12); a second connecting screw (3) corresponding to the first connecting

screw (15) is arranged on the ECU mounting bracket panel (1); and two ends of the storage battery pressing plate (13) are detachably connected with the top of the first connecting screw (15) and the top of the second connecting screw (3) by adopting nuts (16).

[0024] Figs. 1-2 illustrate different perspective views of a mounting structure 100 for battery and an auxiliary component of a vehicle in accordance with an

embodiment of the present disclosure. In an embodiment, the mounting structure 100 includes increased stiffness, and is configured to sustain a weight associated with the battery and the auxiliary component in static as well as dynamic conditions, and without getting deformed under the bending stresses acting on the mounting structure 100.
[0025] Further, the mounting structure 100 includes a battery tray 102 for supporting the battery, and an auxiliary component mount bracket 120 secured to the battery tray 102 for supporting the auxiliary component. Alternatively, the mount bracket 120 may be utilized to secure any auxiliary components like an ECU controller, or CNG controller, or the like. In an embodiment, the mounting structure 100 allows the battery tray 102 to mount on two different levels, thereby increasing the mounting compatibility with vehicle structure. Further, in another embodiment, the battery tray 102 can also be mounted at same level.
[0026] Fig. 3 illustrates a top view of the battery tray 102 in accordance with an embodiment of the present disclosure. As shown, with combined reference to Figs. 1-3, the battery tray 102 includes a rectilinear base 104 defined by a width W of a first short edge 106 and a second short edge 108. Further, the width W separates a first long edge 110 and a second long edge 112. In an embodiment, the first short edge 106, the second short edge 108, the first long edge 110, and the second long edge 112 being provided with flanges 114. In an example, the flanges 114 provide support and stability to the battery, and further eliminate a probability of slipping of the battery during a crash like situation. Further, the flanges 114 of the first short edge 106 and the second short edge 108 include smooth bends. In an example, the battery tray 102 is mounted on the vehicle body at four bolting points. The four bolting points include two rear mounting points on left-hand engine mount, and two front mounting points on a battery bracket (not shown in figs. 1-2). The battery bracket and the left-hand engine mount are connected to long member through spot welds and bolts respectively. The auxiliary component mount bracket 120 is spot welded on the battery tray 102. The battery is placed on

the battery tray 102 using battery bands, and the auxiliary component is mounted on the auxiliary component mount bracket 120.
[0027] Further in an embodiment, the battery tray 102 includes a plurality of beads 116a, 116b, 116cdisposed on the base 104 in an I-shaped bead pattern. In an embodiment, the I-shaped bead pattern provides strength to the battery tray 102 to withstand weight of the battery and the auxiliary component. The I-shaped bead pattern further eliminates the excessive bending phenomena. Further, the bead 116a is proximal to the first short edge 106 and is contained within the width W of the battery tray 102. The bead 116b is proximal to the second short edge 108 and is substantially along the width W of the battery tray 102. Next, the bead 116c is provided intermediate to the bead 116a and 116b. In an example, the bead 116c defines a transverse portion 117a along a central axis O-O' of the base 104 and a lateral member 117b extending towards the second long edge 112. In an example, the lateral member 117b includes a dendritic bead design and provides strength to the battery tray 102 and eliminates excessive bending phenomena under weight of the battery and the auxiliary component.
[0028] Fig. 4a illustrates an enlarged view of a portion of the battery tray 102 of Fig. 3, depicting the bead 116b. Fig. 4b provides a sectional view of the bead 116b about a plane A-A' of Fig. 4a. In an example, the Section A-A' improves the localized strength of the battery tray 102 and eliminates the stress concentration completely. In an example, the bead 116b includes a stepped profile with an increased section height, the stepped profile being provided with two battery tray mounting points.
[0029] Fig. 5a illustrates another enlarged view of a portion of the battery tray 102 of Fig. 3, depicting the bead 116a. In an embodiment, the bead 116a defines a rectilinear profile with large edges 118a and small edges 118b. Further in an embodiment, the small edges 118b of the bead 116a includes octagonal shape beads 119. In an example, provision of the octagonal shape beads 119 is for countering high stress concentration zones developing near the bead 116a. Further, the octagonal shape beads 119 are provided on the battery tray 102 for

increasing localized strength in view of a constrained space situation. Fig. 5b provides a sectional view of the bead 116a about a plane B-B' of Fig. 5a. As shown, section B-B' includes an increased angle of slant that makes the slope more gradual and decreases the flat region. In an example, section B-B' helps in reducing the excessive bending phenomena, and a vertical height associated with Section B-B' eliminates probability of the battery slipping forward in case of crash scenario. Further, section B-B' improve the stability of the battery tray 102. In an example, the sections A-A' and B-B' may include similar or different depths.
[0030] Referring to Figs. 1-2, the mounting structure 100 further includes the auxiliary component mount bracket 120. In an example, the auxiliary component mount bracket 120 is secured to the battery tray 102 through one of spot welding and bolts. In an embodiment, the auxiliary component mount bracket 120 includes a central member 122 disposed on the flange 114 of the second long edge 112, and the auxiliary component mount bracket 120 is secured to the battery tray 102 about the central member 122. The auxiliary component mount bracket 120 further includes a plurality of extensions 124 extending upward and downward from the central member 122, the central member 122 being in a reference plane "RP", and protruding in a first plane "FP" away from the base 104 and the reference plane "RP". The auxiliary component mount bracket 120 further includes a plurality of auxiliary component mounting points 130 extending upward and downward from the plurality of extensions 124 and protruding in a second plane "SP" away from the first plane "FP", the base 104, and the reference plane "RP". In an example, the auxiliary component mount bracket 120 includes the aforementioned three planes concept that increases the strength of the auxiliary component mount bracket 120 to withstand the loads, as the three planes provide a discontinuous bending axis along the auxiliary component mount bracket 120, as against a straight bending axis. Such a discontinuous bending axis provides effective distribution of load, thereby enabling less deformation.

[0031] Further in an embodiment, the auxiliary component mount bracket 120 includes a continuous flange 126 extending arcuately across the central member 122 and the plurality of extensions 124. In an example, the continuous flange 126 is secured to the flange of the short edge 108. The auxiliary component mount bracket 120 further includes a vertical arcuate flange 128 opposite to the continuous flange 126 and extending across the central member 122 and the plurality of extensions 124. In an embodiment, an orientation and structure of the auxiliary component mount bracket 120 is such that a cross-section F-F of Fig. 1, along the central member 122, the continuous flange 126, and the vertical arcuate flange 128 defines an S-shape section (Shown in Fig. 6b). Further in an embodiment, the continuous flange 126, the vertical arcuate flange 128, and the associated S-section provides strength to the auxiliary component mount bracket 120 against excessive bending deformation, as the S-shape section provides a discontinuous bending axis across different planes, as against a straight bending axis. Such a discontinuous bending axis provides effective distribution of load, thereby enabling less deformation.
[0032] Figs. 6a and 6b, provides respective sectional views of the auxiliary component mount bracket 120 about the planes C-C and F-F of Fig. 1. In an example, a U-shape of sections C-C of the auxiliary component mounting points 130, and the S-shape of section F-F improve the strength of the auxiliary component mount bracket 120. In an example, the auxiliary component mount bracket 120 includes less weight and a decreased length as compared to conventional mounting brackets.
[0033] Fig. 7 illustrates a sectional view of the auxiliary component mount bracket 120 about the plane E-E of Fig. 1. As described earlier, the auxiliary component mount bracket 120 is structured in the three planes with the plurality of extensions 124 extending upward and downward from the central member 122 and protruding in the first plane "FP" away from the base 104, and the plurality of auxiliary component mounting points 130 extending upward and downward from

the plurality of extensions 124 and protruding in the second plane "SP" away from the first plane "FP", and the base 104.
[0034] Although embodiments for the present subject matter have been described in language specific to structural features, it is to be understood that the present subject matter is not necessarily limited to the specific features described. Rather, the specific features and methods are disclosed as embodiments for the present subject matter. Numerous modifications and adaptations of the system/component of the present invention will be apparent to those skilled in the art, and thus it is intended by the appended claims to cover all such modifications and adaptations which fall within the scope of the present subject matter.
