DESC:AN INTEGRATED REINFORCEMENT ASSEMBLY FOR A VEHICLE
DESCRIPTION
Technical Field
[001] This disclosure relates generally to automobiles, and more particularly to a sill reinforcement assembly.
Background
[002] With the increase of usage and productivity of the electric vehicles (EVs), there has been a lot of scope in enhancing safety of the structures of EVs, especially where the batteries are placed. The EV batteries are generally placed in the sill portion below the cabin space of vehicle. Apart from the sill portion, there are other locations where the batteries can be placed, but due to the high volume of the batteries and space constraints, the sill portion area is the most preferred location for position the batteries.
[003] In EVs, the batteries may be protected through guarded assemblies. The protecting may include providing reinforcement at the sill portion below the door assembly and the cabin body of the vehicle. FIG. 1 (PRIOR ART) illustrates one of the conventional reinforcements 100 installed in EVs. The conventional reinforcement 100 is provided by coupling or joining two or more longitudinal sheets which are bent in strips and then joined over each other in mirrored positions. However, the longitudinal sheets in the conventional reinforcement 100 may eventually fail as the longitudinal sheets are shaped for reinforcement by bending but the longitudinal sheets are still susceptible to bend in lateral direction easily.
[004] FIG. 2 (PRIOR ART) illustrates another conventional reinforcement 200. The conventional reinforcement 200 may include longitudinal strips (reinforcement strips) 202 extending along the sill area and an Impact Transmission Structure (ITS) 204 mounted to the longitudinal strips. However, these longitudinal sheets 204 may eventually fail as they are not designed to sustain high impact forces and are susceptible to bending laterally.
[005] There is, therefore, a need to develop and introduce a reinforcing assembly which can sustain and absorb high impact forces and should not bend in order to protect the batteries from getting damaged in case of any accidental situation (such as a side collision) of the vehicle.
[006] The present invention is directed to overcome one or more limitations stated above, or any other limitation associated with the known Prior arts.

DETAILED DESCRIPTION
[018] Exemplary embodiments are described with reference to the accompanying drawings. Wherever convenient, the same reference numbers are used throughout the drawings to refer to the same or like parts. While examples and features of disclosed principles are described herein, modifications, adaptations, and other implementations are possible without departing from the spirit and scope of the disclosed embodiments. It is intended that the following detailed description be considered as exemplary only, with the true scope and spirit being indicated by the following claims.
[019] Referring now to FIG. 3, a perspective view of an exemplary sill reinforcement assembly 300 is illustrated, in accordance with some embodiments of the present disclosure. The sill reinforcement assembly 300 may be configured to reinforce a vehicle body against an impact of side collisions. The sill reinforcement assembly 300 herein is also referred to as a composite-sheet metal integrated reinforcement. The sill reinforcement assembly 300 may be installed within a side sill of a vehicle. The side sill may be positioned below a door assembly of the vehicle. This is further explained in greater detail in conjunction with FIGS. 5, 6, and 7. The sill reinforcement assembly 300 may include an elongated member 302. The elongated member 302 may be one of an elongated sheet or an elongated tube. In an embodiment, where the elongated member 302 is the elongated tube, the elongated tube may be of a cylindrical shape (with oval (or elliptical) shaped cross section), a cuboidal shape (with rectangular shaped cross section), or any combination thereof. In a preferred embodiment, the elongated member 302 is of cylindrical shape. The elongated member 302 may be constructed using materials, such as, but not limited to, metal (e.g., aluminum, stainless steel, titanium, alloys thereof, and the like), polymeric material, plastic, a composite of plastic and metal, etc. By way of an example, the elongated member 302 may be a tube with a strength of about 1100 megapascals (MPa).
[020] The elongated member 302 may include a plurality of first locking elements. The locking elements may be, for example, but may not be limited to, a threaded fastener, a key-based locking elements, friction-based locking elements. In an embodiment, the plurality of first locking elements may be embedded on the elongated member 302. For example, the elongated member 302 may include a plurality of externally threaded portions. The plurality of first locking elements in the elongated tube 302 may include a first locking element corresponding to each of a set of cross members in the vehicle. The set of cross members is a structural component of the vehicle that may support the engine and transmission of the vehicle. The vehicle may be, for example, but may not be limited to, Battery Electric Vehicle (BEV), Hybrid Electric Vehicle (HEV), Fuel Cell Electric Vehicle (FCEV), and Solar Electric Vehicles (SEVs). It should be noted that a distance between each of the plurality of first locking elements on the elongated tube 302 is equivalent to a distance between each of the corresponding set of cross members. In an embodiment, a number of the plurality of first locking elements may be equal to a number of the set of cross members in the vehicle.
[021] The sill reinforcement assembly 302 may further include a plurality of reinforcement blocks (e.g., a reinforcement block 304A, a reinforcement block 304B, and a reinforcement block 304C) coupled to the elongated member 302. Each of the plurality of reinforcement blocks may include an insert, a second locking element, and a structural form layer externally adhered to the insert. The insert may include a cavity to facilitate fitting of a reinforcement block around the elongated member 302. It should be noted that the second locking element is configured to engage with a corresponding first locking element of the plurality of the first locking elements to couple an associated reinforcement block on the elongated member 302. Thus, in some embodiments where the plurality of first locking elements may include a plurality of externally threaded portions, the second locking element may include an internally threaded portion located within the insert of each of the plurality of reinforcement blocks. The internally threaded portion is configured to couple to a corresponding externally threaded portion of the plurality of first locking elements. Some other examples of first locking elements and second locking elements may include magnetic locking elements, latch locking elements, etc.
[022] The sill reinforcement assembly 300 may further include at least one mounting bracket (e.g., the mounting bracket 306A and the mounting bracket 306B). The bracket may be constructed using materials such as, metal, plastic, composite of metal and plastic, and the like. The at least one bracket may be, for example, but may not be limited to, an angle bracket, a channel bracket, U-Bracket, Z-Bracket, and a mounting bracket. The at least one mounting bracket 306 is configured to couple the elongated member 302 to an internal surface of the side sill of the vehicle.
[023] It should be noted that when the elongated member 302 is coupled to the internal surface of the side sill, each of the plurality of reinforcement blocks (i.e., 304A, 304B, and 304C) coupled to the elongated member 302 is positioned between the internal surface of the side sill and an external surface of a battery compartment. The battery compartment may include one or more batteries to provide energy for a motor or engine of the vehicle. The plurality of reinforcement blocks may include a reinforcement block corresponding to each of the plurality of first locking elements (or the set of cross members) in the vehicle. Thus, when the elongated member 302 is mounted to the internal surface of the side sill, and when the reinforcement block is coupled to the elongated member 302, the reinforcement block is in line with a corresponding cross member. In some embodiments, each of the plurality of reinforcement blocks is in contact with a corresponding cross member when the reinforcement block is coupled to the elongated member 302 mounted to the internal surface of the side sill.
[024] Referring now to FIG. 4, an exploded view 400 of the sill reinforcement assembly 300 is illustrated, in accordance with some embodiments of the present disclosure. FIG. 4 is explained in conjunction with FIG. 3. The sill reinforcement assembly 300 may include the elongated member 302. The elongated member 302 is of cylindrical shape. The elongated member 302 may include a plurality of first locking elements. The sill reinforcement assembly 300 may further include the plurality of reinforcement blocks (i.e., the reinforcement block 304A, the reinforcement block 304B, and the reinforcement block 304C) and the at least one mounting bracket (i.e., the mounting bracket 306A and the mounting bracket 306B). Each of the reinforcement blocks may include an insert, a second locking element, and a structural form layer externally adhered to the insert. By way of an example, the reinforcement block 304A may include an insert 402A, a second locking element (not shown), and a structural foam layer 404A. Similarly, the reinforcement block 304B and the reinforcement block 304C may include an insert 402B and an insert 402C, respectively, and may include a structural foam layer 404B and a structural foam layer 404C, respectively.
[025] The insert may be constructed using materials, such as metal, plastic, composite of metal and plastic, and the like. The insert may be configured to absorb energy (or force) generated during an impact (such as vehicle accident, side pole collision, and the like) to enhance the vehicle’s safety. The insert is preferably a sheet metal which may enable a smooth absorption and transfer of load. Each structural form layer may be configured to absorb and sustain the forces during the impact. Additionally, each structural foam layer may provide added protection (or defence) to the elongated member 302 again bending or breaking during the impact of a side collision.
[026] By way of an example, Table 1 describes various physical properties of the insert (i.e., carrier) and the structural foam for an exemplary sill reinforcement assembly (such as the sill reinforcement assembly 300), in accordance with an embodiment.

[027] Referring now to FIG. 5, the sill reinforcement assembly 300 installed within a vehicle 500 is illustrated, in accordance with some embodiments of the present disclosure. FIG. 5 is explained in conjunction with FIGS. 3 and 4. The vehicle 500 (e.g., Body-in-White (BIW)) may include a side sill 502. The side sill 502 may be positioned below a door assembly throughout a cabin body of the vehicle 500. The sill reinforcement assembly 300 may be placed within the side sill 502 using the at least one bracket 306 (e.g., U-Brackets). The sill reinforcement assembly 300 may include the elongated member 302. The sill reinforcement assembly 300 may further include the plurality of reinforcement blocks (i.e., the reinforcement block 304A, the reinforcement block 304B, and the reinforcement block 304C). The vehicle 500 may further include a set of cross members (e.g., a cross member 504A, a cross member 504B, and a cross member 504C). The plurality of reinforcement blocks may include the reinforcement block corresponding to each of the set of cross members in the vehicle 500. When the sill reinforcement assembly 300 is installed in the vehicle 500 (i.e., when the elongated member 302 is mounted to the inner surface of the side sill of the vehicle), each reinforcement block is in line with a corresponding cross member. By way of example, the reinforcement block 304A is in line with the cross member 504A. In some embodiments, each of the plurality of reinforcement blocks is in contact with a corresponding cross member when the reinforcement block is coupled to the elongated member 302 mounted to the internal surface of the side sill 502. Similarly, the sill reinforcement assembly 300 may also be placed on the other side sill of the vehicle 500. This may create a side-to-side load path so as to transfer load (i.e., impact) of the side collision to other side of the vehicle. Thus, the load is distributed and impact of the side collision on the battery compartment may be reduced. This is explained in greater detail in conjunction with FIG. 7.
[028] Referring now to FIG. 6, a cross-sectional view 600 of the vehicle 500 is illustrated, in accordance with some embodiments of the present disclosure. FIG. 6 is explained in conjunction with FIG. 5. The sectional view 600 may be represented along the ‘XX’ axis to represent the sill reinforcement assembly 300 integrated within the side sill 502. The vehicle 500 may include the side sill 502. The side sill 502 may include the sill reinforcement assembly 300. The sill reinforcement assembly 300 may include the elongated member 302. The sill reinforcement assembly 300 may further include the reinforcement block 304A. The reinforcement block 304A may correspond to the cross member 504A. The reinforcement block 304A is in line with a corresponding cross member 504A when the reinforcement block 304A is coupled to the elongated member 302 mounted to the internal surface of the side sill 502.
[029] Referring now to FIG. 7, a top sectional view 700 of an exemplary vehicle 500 is illustrated, in accordance with some embodiments of the present disclosure. The vehicle 500 may include a side sill (e.g., a side sill 702A and a side sill 702B). Each of the side sill 702A and the side sill 702B may be analogous to the side sill 502. By way of an example, the side sill 702A may be positioned below a door assembly corresponding to one side (e.g., side A) of the vehicle 500. Similarly, the side sill 702B may be positioned below the door assembly corresponding to the other side (e.g., side B) of the vehicle 500. The vehicle 500 may further include a battery compartment 704. The battery compartment 704 may be positioned between the side sill 702A and the side sill 702B. The battery compartment 704 may include one or more batteries of the vehicle 500. The one or more batteries may be, for example, but may not be limited to, Lithium-ion batteries, Lithium Ferrous Phosphate (LFP) batteries, and Nickel Manganese Cobalt (NMC) batteries.
[030] The vehicle 500 may further include a sill reinforcement assembly (e.g., the sill reinforcement assembly 706A and the sill reinforcement assembly 706B). Each sill reinforcement assembly may be analogous to the sill reinforcement assembly 300. The sill reinforcement assembly is positioned between the side sill and the battery compartment 704. By way of an example, the sill reinforcement assembly 706A is positioned between the side sill 702A and the battery compartment 704. Similarly, the sill reinforcement assembly 706B is positioned between the side sill 702B and the battery compartment 704.
[031] The sill reinforcement assembly may include an elongated member (such as the elongated member 302). By way of an example, both sill reinforcement assemblies (i.e., the sill reinforcement assembly 706A and the sill reinforcement assembly 706B) may include an elongated member (e.g., an elongated member 708A and an elongated member 708B) respectively. Each elongated member (i.e., the elongated member 708A and the elongated member 708B) may include a plurality of first locking elements. It should be noted that each elongated member is an elongated tube. The sill reinforcement assembly may include a plurality of reinforcement blocks. In continuous with the above example, the sill reinforcement assembly 706A may include three reinforcement blocks (e.g., a reinforcement block 710A, a reinforcement block 710B, and a reinforcement block 710C). Similarly, the sill reinforcement assembly 706B may also include three reinforcement blocks (e.g., a reinforcement block 712A, a reinforcement block 712B, and a reinforcement block 712C).
[032] Each of the reinforcement blocks may include an insert, a second locking element, and a structural foam layer externally adhered to the insert. The second locking element is configured to engage with a corresponding first locking element of the plurality of locking elements to couple an associated reinforcement block on the elongated member.
[033] The sill reinforcement assembly may further include at least one mounting bracket (such as the mounting bracket 306). The at least one mounting bracket is configured to couple the elongated member to an internally surface of the side sill. By way of an example, the elongated member 708A is coupled to an internal surface of the side sill 702A using the brackets. In the same manner, the elongated member 708B is coupled to an internal surface of the side sill 702B using the brackets.
[034] Further, when the elongated member is coupled to the internal surface of the side sill, each of the plurality of reinforcement blocks coupled to the elongated member is positioned between the internal surface of the side sill and an external surface of the battery compartment 704. By way of an example, once the elongated member 708A is coupled to the internal surface of the side sill 702A, then each of the three reinforcement blocks (i.e., the reinforcement block 710A, the reinforcement block 710B, and the reinforcement block 710C) coupled to the elongated member 708A is positioned between the internal surface of the side sill 702A and the external surface of the battery compartment 704. Similarly, each of the three reinforcement blocks (i.e., the reinforcement block 712A, the reinforcement block 712B, and the reinforcement block 712C) coupled to the elongated member 708B is positioned between the internal surface of the side sill 702B and the external surface of the battery compartment 704.
[035] The vehicle 500 may further include a set of cross members (e.g., a cross member 714A, a cross member 714B, and a cross member 714C). In an embodiment, the cross member 714A, the cross member 714B, and the cross member 714C may be analogous to the cross member 504A, the cross member 504B, and the cross member 504C, respectively. By way of an example, the cross member 714A may be a front seat cross member, the cross member 714B may be a middle cross member, and the cross member 714C may be a rear seat cross member. It should be noted that the plurality of first locking elements in the elongated tube may include a first locking element corresponding to each of the set of cross members. The distance between each of the plurality of first locking elements on the elongated tube is equivalent to a distance between each of the corresponding set of cross members. By way of an example, both the elongated tubes (i.e., 708A, and 708B) may include the first locking element corresponding to each of the three cross members.
[036] The plurality of reinforcement blocks may include a reinforcement block corresponding to each of the set of cross members. The reinforcement block is in line with a corresponding cross member when the reinforcement block is coupled to the elongated member mounted to the internal surface of the side sill. By way of an example, each reinforcement block (i.e., the reinforcement block 710A, the reinforcement block 710B, and the reinforcement block 710C) is in line with the corresponding cross member (i.e., the cross member 714A, the cross member 714B, and the cross member 714C) when the reinforcement blocks are coupled to the elongated member 708A mounted to the internal surface of the side sill 702A. Similarly, the reinforcement block 712A, the reinforcement block 712B, and the reinforcement block 712C are in line with the cross member 714A, the cross member 714B, and the cross member 714C, respectively when the reinforcement blocks are coupled to the elongated member 708B mounted to the internal surface of the side sill 702B.
[037] In some embodiments, the plurality of reinforcement blocks is in contact with a corresponding cross member when the reinforcement block is coupled with the elongated member mounted to the internal surface of the side sill.
[038] By way of an example, consider a scenario in which the vehicle 500 may be collided with a side pole 516. During the collision, a large amount of force (or load) may be exerted on the side sill 702A of the vehicle 500. In such a scenario, the force may be transferred from the side sill 702A of the vehicle to the reinforcement blocks of the sill reinforcement assembly. Further, the plurality of reinforcement blocks and structural foam layers may partially absorb the forces. Further, the remaining loads may be transferred to the other side sill 702B of the vehicle though the load paths created from the reinforcement blocks to the corresponding set of cross members to reduce the load on the battery compartment 704. Due to transfer of loads from the impacted sill reinforcement assembly to the other sill reinforcement assembly through the set of cross members, the load is equally dissipated throughout the set of cross members and both the side sills of the vehicle. Thus, due to the strategic arrangement of the plurality of reinforcement blocks, the battery compartment is safeguarded from the side pole impact.
[039] By way of an example, Table 2 represents a comparison of the sill reinforcement assembly of the present disclosure (such as the sill reinforcement assembly 300) with a baseline (no sill reinforcement assembly) and other sill reinforcement assemblies for a vehicle, in accordance with an embodiment. The vehicle used is an Eturna® AWD DV0 4x4-Battery pack (76KWH) by Tata Motors®. Experimental samples include baseline (no sill reinforcement assembly installed in the vehicle), a reinforcement assembly of aluminium extrusion (a bare metal elongated member), a reinforcement assembly including an elongated member covered with an insert made up of structural foam throughout the length, and the reinforcement assembly 300 including an elongated member covered with reinforcement blocks (a plastic insert block covered with structural foam). A side collision is simulated for each of the 4 experimental samples. Compared to the baseline which observed a battery cell (i.e., battery compartment) load of 350 kN, the aluminium extrusion observed a battery cell load of 257 kN, the full length structural sill insert observed a battery cell load of 355 kN, and the reinforcement assembly 300 observed a battery cell load of 237 kN and 32 kN.
