Description

Technical Field

[0001] This invention relates to the field of electric or hybrid motor transport vehicles, and more particularly to a battery holder designed to house all or part of a battery supported by the battery holder.

[0002] More specifically, the present invention relates to components for such battery holders. Background Technology

[0003] The prior art described below presents applications in the field of electric or hybrid vehicles, but it may also apply to other fields or applications that require the use of battery holders.

[0004] According to existing technology, a battery casing is known to have a structural frame designed to support the battery and ultimately protect the battery cells or modules from damage and environmental intrusion in the event of a collision or impact. The battery casing typically includes the following components:

[0005] - A circumferential structural frame, which is typically fastened to the vehicle body structure using a bolted connection system;

[0006] - A base plate, which encloses the bottom of the frame and is configured to house all or part of the battery cells or modules;

[0007] - A cover, made of plastic, steel or aluminum, is placed on top of the aforementioned structure to completely seal the battery casing.

[0008] The purpose of the casing is to house and protect the battery cells or modules. However, the overall shape of the frame can vary significantly depending on requirements and the type of battery cells or modules intended to be supported by the battery holder. In fact, the battery system of an electric vehicle is constructed from a combination of multiple individual cells. There are generally three main cell types, which determine the geometry, size, driving range, and damage resistance of the energy storage system. Therefore, the type of cell chosen will influence the final design and shape of the battery casing.

[0009] The first primary characteristic a battery casing should possess is sufficient robustness to reduce the likelihood of deformation in the event of improper vehicle use or an accident. For this reason, the battery casing must be strong enough to minimize the possibility of damage to its internal components, which could ultimately cause serious harm to the vehicle and its surrounding environment. To achieve the required structural rigidity, internal components are used to create connections between the various parts of the structural frame. Typical components used in this way are crossbeams. These crossbeams allow for the housing of battery cells or modules, along with increasing the overall mechanical resistance of the battery pack.

[0010] The second primary characteristic that a battery casing must possess is that it must meet mandatory standards, such as airtightness. That is, water or any other foreign matter must not seep into or enter the battery casing.

[0011] The third important technical feature that the battery casing should have is light weight, in order to reduce the overall energy consumption and cost of the vehicle.

[0012] In some applications, it is necessary to reduce the overall space of the battery holder. Reducing the size of the battery holder allows for adaptation to tighter spaces within a vehicle and can help reduce the weight of the battery holder, thereby reducing the weight of the vehicle. To this end, a battery holder can be designed in which individual battery cells or modules are directly fixed to the housing. However, this configuration exacerbates space constraints, making bracket-based external bonding methods challenging or impossible. In cases where the battery holder includes crossbeams, one approach is to weld the crossbeams. However, welding introduces a cascading effect, namely, introducing tolerance constraints to the outer frame of the housing.

[0013] Therefore, there is an urgent need to find a solution that can increase space for accommodating the largest number of battery cells or battery modules without increasing the overall size of the battery holder, while maintaining good mechanical strength of the battery holder. Summary of the Invention

[0014] The present invention aims to solve the above-mentioned problems. To this end, the present invention relates to an assembly for a battery holder, the battery holder comprising a frame and a base plate defining a housing therebetween for accommodating all or part of a battery, the assembly comprising:

[0015] - A structural profile, the structural profile being designed to form at least a portion of the frame of the battery holder, the structural profile extending along a primary direction;

[0016] - A connection node, which is fixed to the structural profile and abuts against the structural profile along a mating surface, the mating surface being generally planar and generally parallel to the main direction;

[0017] - A reinforcing beam, the reinforcing beam including at least one connecting housing configured to allow the reinforcing beam to slide relative to the connecting node in a sliding direction, the reinforcing beam being configured to change configuration between an unassembled configuration and an assembled configuration, in the unassembled configuration the reinforcing beam being separated from the connecting node, and in the assembled configuration the connecting node being at least partially inserted into the connecting housing of the reinforcing beam.

[0018] The arrangement described above allows for the provision of an assembly for a battery holder, in which individual batteries can be directly bonded to the frame of the battery holder. In effect, the connection nodes inserted into the connecting housing allow for a robust connection between the side structural profiles and the reinforcing beams, while also allowing for increased battery packaging space without increasing the overall internal perimeter of the frame.

[0019] According to one implementation, the component includes one or more of the following features, either individually or in combination.

[0020] According to one embodiment, the battery intended to be supported by the battery holder can be any type of battery, including, for example, cylindrical cells, prismatic cells, pouch cells and / or battery modules.

[0021] According to one implementation, the main direction is the longitudinal direction, for example, the direction in which the electric vehicle travels.

[0022] According to one embodiment, the connecting housing is a hollow cavity.

[0023] According to one embodiment, at least one element selected from the reinforcing beam, the structural profile, and the connection node is a solid profile.

[0024] According to one embodiment, when the reinforcing beam is in an assembled configuration, the reinforcing beam extends along a secondary direction that is substantially perpendicular to the primary direction.

[0025] Therefore, quadrilateral battery cells or modules can be housed within a housing defined by the frame of the battery holder.

[0026] "Approximately perpendicular" means that the angle between the primary direction X and the secondary direction Y is between 85° and 95°.

[0027] According to one implementation scheme, the angle formed between the primary direction X and the secondary direction Y is between 70° and 110°.

[0028] According to one implementation, the secondary direction is a lateral direction, for example, a direction perpendicular to the direction of travel of the electric vehicle.

[0029] According to one embodiment, the secondary direction is perpendicular to the primary direction and perpendicular to the sliding direction.

[0030] According to one embodiment, when the reinforcing beam is in an assembled configuration, the distance between the reinforcing beam and the structural profile is less than 10 mm, preferably less than 2 mm, and particularly approximately equal to 0 mm.

[0031] In other words, when the stiffening beam is in an assembled configuration, it can be in contact with or close to the structural profiles. It should be understood that the stiffening beam is configured to fit the separated lengths of two opposing structural profiles of the frame.

[0032] According to one embodiment, when the reinforcing beam is in the assembled configuration, the distance between the reinforcing beam and the structural profile is less than 5 mm, preferably less than 1 mm.

[0033] Therefore, the reinforcing beams and structural profiles can be fixed without welding. Furthermore, using smaller gaps to assemble the reinforcing beams and structural profiles allows for better impact resistance. In practice, direct welding between the reinforcing beams and structural profiles requires much stricter gap control and could potentially over-constrain the frame structure.

[0034] According to one embodiment, when the reinforcing beam is in an assembled configuration, the connection node is completely contained within a cylinder defined by the reinforcing beam.

[0035] A "cylinder" refers to a volume defined by a cylindrical surface. The cylindrical surface is generated by straight lines called generatrices, which move in a given direction based on closed curves called directrixes. In this example, the directrix corresponds to the profile of the cross-section of the reinforcing beam at the level connecting the outer shell, and the generatrices are parallel to the secondary direction.

[0036] In other words, the connection node is entirely contained within the footprint of the connection shell on the structural profile.

[0037] According to one embodiment, the connecting node has an external adhesive surface on the outside, and the reinforcing beam has an internal adhesive surface facing the external adhesive surface of the connecting node on the inside. The assembly further includes an adhesive element disposed between the external adhesive surface and the internal adhesive surface, the adhesive element being configured to adhesive the connecting node to the reinforcing beam at the level of the external adhesive surface and the internal adhesive surface when the reinforcing beam is in an assembled configuration.

[0038] Therefore, when the reinforcing beam is in an assembled configuration, the mechanical strength of the component is greater.

[0039] Advantageously, the use of adhesive bonding allows for the manufacture of components with larger clearance tolerances separating the reinforcing beams from the structural profiles compared to traditional clearance compensation methods such as welding.

[0040] According to one embodiment, the adhesive element may include an adhesive selected from epoxy resins, methyl methacrylates, acrylates, polyurethanes, silane-terminated polymers, or equivalents.

[0041] According to one embodiment, the reinforcing beam includes a connecting end, the connecting end including at least two walls that internally define the connecting housing, the connecting end being configured to allow the reinforcing beam to slide relative to the connecting node.

[0042] This facilitates the sliding of the beam around the connection node.

[0043] According to one embodiment, the connecting end has an internal abutment surface, and when the reinforcing beam is in an assembled configuration, the connecting node is configured to abut against the abutment surface.

[0044] This prevents the reinforcing beam from sliding in the sliding direction.

[0045] According to one embodiment, the connecting node has a supporting surface facing the abutting surface of the reinforcing beam, and the connecting node includes at least one insertion corner adjacent to the supporting surface, the at least one insertion corner being arc-shaped.

[0046] This guides and facilitates the insertion of the beam at the horizontal position of the insertion corner.

[0047] According to one embodiment, at least two walls of the connecting end include a central wall and two opposing transverse sidewalls extending from the central wall; each transverse sidewall includes a proximal end attached to the central wall and a distal end opposite to the proximal end.

[0048] Therefore, the shape of the connecting end is adapted to fit the connecting node.

[0049] According to one embodiment, the connecting end has a hollow U-shape, a hollow H-shape, or a hollow C-shape.

[0050] According to one embodiment, the distance between the two opposing sidewalls at the horizontal level of the proximal end is strictly less than the distance between the two opposing sidewalls at the horizontal level of the distal end.

[0051] This facilitates the insertion of the reinforcing beam along the sliding direction.

[0052] In other words, the opposite sidewalls are slightly tapered.

[0053] According to one embodiment, the connection node includes two opposing adhesive surfaces on two opposing sidewalls facing the connection end of the reinforcing beam, wherein the distance between the two opposing adhesive surfaces at the horizontal level of the proximal end is strictly less than the distance between the two opposing adhesive surfaces at the horizontal level of the distal end.

[0054] In other words, the opposing adhesive surfaces of the connecting nodes are slightly tapered.

[0055] In conjunction with this, the slight tapering allows for the avoidance of scraping off the adhesive elements when the connecting nodes are bonded to the reinforcing beams.

[0056] According to one embodiment, the connection node is formed from an extruded profile.

[0057] This reduces the manufacturing cost of the connection nodes.

[0058] According to one embodiment, at least one element selected from the structural profile, the connection node, and the reinforcing beam is made of aluminum alloy.

[0059] According to one embodiment, the component includes at least one fixing element configured to allow the connection node to be secured to the structural profile.

[0060] This improves the mechanical strength of the connection between the structural profile and the connection node.

[0061] According to one embodiment, the at least one fixing element is configured to allow reversible fixing between the connection node and the structural profile.

[0062] According to one embodiment, the at least one fixing element includes a bolt configured to be fixed to a blind hole nut disposed in the structural profile.

[0063] According to one embodiment, the connection node is fixed to the structural profile by at least one bolt.

[0064] For example, each bolt can be connected to the structural profile via a sealed blind-hole rivet nut. The blind-hole rivet nut can be placed within the inner wall of the structural profile. This bolted connection ensures adequate support when the connection node is subjected to shear loads.

[0065] Alternatively, each bolt can be connected to the structural profile via a sealing element (such as a sealing ring) through a threaded hole arranged in the structural profile. This allows the connection point to be secured to the structural profile while maintaining a tight seal.

[0066] The object of the present invention can also be achieved by implementing a battery holder for a transport vehicle, the battery holder comprising a frame and a base plate defining a housing therebetween intended to accommodate all or part of a battery, the frame comprising at least one component as described above.

[0067] The object of the present invention can also be achieved by implementing an electric or hybrid motor transport vehicle, which includes a battery holder as described above. Attached Figure Description

[0074] Figure 6 This indicates different variations at the connection ends of the reinforced beam. Detailed Implementation

[0075] In the remainder of the accompanying drawings and description, the same reference numerals denote the same or similar elements. Furthermore, for clarity, the elements are not shown to scale. Additionally, different embodiments and variations are not mutually exclusive and can be combined with each other.

[0076] As illustrated in the figure, the present invention relates to an assembly 10 for a battery holder 1. The invention also relates to a battery holder 1 for a transport vehicle, the battery holder including such an assembly 10. Furthermore, the invention relates to an electric or hybrid electric transport vehicle including such a battery holder 1.

[0077] Typically, the battery holder 1 includes a frame 2 and a base plate 3, which define a housing between them designed to accommodate all or part of the battery. The battery intended to be supported by the battery holder 1 can be any type of battery, including, for example, cylindrical cells, prismatic cells, pouch cells, and / or battery modules.

[0078] The battery holder 1 typically includes a cover (not shown), preferably made of plastic, which is attached to the frame 3 to close the housing. Figure 1 and Figure 2An embodiment of the battery holder 1 is illustrated, wherein the frame 2 includes two lateral structural profiles 11, a front profile 4, and a rear profile 5, the two lateral structural profiles extending along a main direction referred to as "X" (which corresponds to the direction of travel of the electric vehicle). In this embodiment, the frame 2 has a generally quadrilateral shape. However, this shape is not limiting, and the frame 2 may have any other shape depending on the battery to be supported. A reinforcing beam 13 is also shown in the figure, which is disposed inside the frame 2 and fixed to the two lateral structural profiles 11. The component 10 according to the invention is intended to be part of such a battery holder 1.

[0079] In fact, according to the present invention and Figures 3 to 5 The illustrated component 10 includes a structural profile 11 designed to form at least a portion of the frame 2 of the battery holder 1. The structural profile 11 extends along a primary direction X. Typically, the primary direction X is a longitudinal direction, for example, corresponding to the direction of travel of an electric vehicle.

[0080] The component 10 also includes a connecting node 30, which is fixed to the structural profile 11 and abuts against the structural profile 11 along a mating surface si30. The mating surface si30 is generally planar and substantially parallel to the principal direction X.

[0081] The component 10 also includes a reinforcing beam 13, which includes at least one connecting housing 15 (e.g., a hollow cavity) and is configured to allow the reinforcing beam 13 to slide relative to the connecting node 30 in a sliding direction referred to as "S". The reinforcing beam 13 is configured to change configuration between an unassembled configuration C1 and an assembled configuration C2, in which the reinforcing beam 13 is separated from the connecting node 30, and in the assembled configuration C2, the connecting node 30 is at least partially inserted into the connecting housing 15 of the reinforcing beam 13.

[0082] According to one embodiment, at least one element selected from the reinforcing beam 13, structural profile 11, and connecting node 30 is a solid profile. Alternatively, at least one element selected from the reinforcing beam 13, structural profile 11, and connecting node 30 is a hollow profile. Using a hollow profile can help reduce the overall weight of the assembly 10. More specifically, the connecting node 30 can be formed from an extruded profile. Therefore, the manufacturing cost of the connecting node 30 is reduced. Furthermore, at least one element selected from the structural profile 11, connecting node 30, and reinforcing beam 13 is made of aluminum alloy.

[0083] like Figures 3 to 5As illustrated, when the reinforcing beam 13 is in the assembly configuration C2, the reinforcing beam 13 can extend along a secondary direction referred to as "Y," which is approximately perpendicular to the primary direction X. Therefore, a quadrilateral battery cell or module can be housed within a casing defined by the frame 2 of the battery holder 1. "Approximately perpendicular" means that the angle formed between the primary direction X and the secondary direction Y is between 85° and 95°. However, this configuration is not limiting, and it is also possible for the angle formed between the primary direction X and the secondary direction Y to be between 70° and 110°.

[0084] When the secondary direction Y is approximately perpendicular to the primary direction X, it is possible that the secondary direction Y is a lateral direction, for example, corresponding to a direction perpendicular to the direction of travel of the electric vehicle. Furthermore, the secondary direction Y can be perpendicular to the primary direction X and perpendicular to the sliding direction S. The sliding direction S can be parallel to or coincide with a vertical direction referred to as "Z," which is defined laterally to the plane formed by the primary direction X and the secondary direction, and particularly perpendicular to this plane. Therefore, a spatial reference associated with the battery holder 1 can be defined, for example, attached to the base plate 5. This spatial reference may include the following three axes:

[0085] - The main direction X is designed to extend longitudinally along the vehicle's direction of travel;

[0086] - Secondary direction Y, which extends laterally in the plane of the base plate 5 and is approximately perpendicular to the axis X;

[0087] - Vertical direction Z, which extends laterally relative to the plane of the base plate 5.

[0088] Despite Figures 3 to 5 as well as Figure 6 A to Figure 6 As can be seen from C, the sliding direction S can be perpendicular to the main direction X, but it is also possible that the sliding direction is parallel to or coincides with the main direction X, such as... Figure 6 D is an example.

[0089] like Figure 3 and Figure 4 As illustrated, the reinforcing beam 13 includes connecting ends 16. More specifically, the reinforcing beam 13 may include two opposing connecting ends 16, each connecting end 16 facing its respective opposing structural profile 11. The connecting ends 16 may include at least two walls 17, 18 internally defining a connecting housing 15. The connecting ends 16 are configured to allow the reinforcing beam 13 to slide relative to the connecting node 30. Thus, sliding of the reinforcing beam 13 around the connecting node 30 is facilitated.

[0090] Figure 6 Different variations of the cross-section of the connecting end 16 are illustrated. Figure 6C depicts a connecting end 16 with two transverse sidewalls 18 extending from the remainder of the reinforcing beam 13. The transverse sidewalls 18 are offset from each other relative to the sliding direction S, which extends perpendicular to the primary direction X and the secondary direction Y.

[0091] Figure 6 A, Figure 6 B and Figure 6 D represents the connecting end 16, wherein at least two walls 17, 18 of the connecting end 16 include a central wall 17 and two opposing transverse sidewalls 18 extending from the central wall 17. Each transverse sidewall 18 includes a proximal end p18 attached to the central wall 17 and a distal end d18 opposite to the proximal end p18. Therefore, the shape of the connecting end 16 is adapted to mate with the connecting node 30. For example, the connecting end 16 may be hollow U-shaped ( Figure 6 A) Hollow H-shaped ( Figure 6 B) or hollow C-shaped ( Figure 6 D).

[0092] It may be advantageous that the distance between the two opposing sidewalls 18 at the proximal p18 level is strictly smaller than the distance between the two opposing sidewalls 18 at the distal d18 level. In other words, the opposing sidewalls 18 are slightly tapered. This facilitates the insertion of the reinforcing beam 13 along the sliding direction S.

[0093] like Figure 6 A and Figure 6 As depicted in B, the connecting end 16 may have an internal abutment surface s16, on which the connecting node 30 is configured to abut when the reinforcing beam 13 is in the assembly configuration C2. This prevents the reinforcing beam 13 from sliding in the sliding direction S.

[0094] It may be advantageous that the connecting node 30 has a supporting surface ss30 facing the abutting surface s16 of the reinforcing beam 13, and the connecting node 30 includes at least one insertion corner 32 adjacent to the supporting surface ss30, the at least one insertion corner 32 being rounded. This guides and facilitates the insertion of the reinforcing beam 13 at the level of the insertion corner 32.

[0095] The connecting node 30 may include two opposing adhesive surfaces facing two opposing sidewalls 18 of the connecting end 16 of the reinforcing beam 13. Furthermore, it is possible that the distance between the two opposing adhesive surfaces at the proximal end p18 level is strictly less than the distance between them at the distal end d18 level. In other words, the opposing adhesive surfaces of the connecting node 30 are slightly tapered. Thus, the tapering of the adhesive surfaces matches the tapering of the transverse sidewalls 18 of the connecting end 16. Collaboratively, when the connecting node 30 is bonded to the reinforcing beam 13, this slight tapering allows for the avoidance of scraping of the adhesive element 20, as described below.

[0096] Typically, when the reinforcing beam 13 is in assembly configuration C2, the connecting node 30 is entirely contained within the cylinder defined by the reinforcing beam 13. A "cylinder" refers to a volume defined by a cylindrical surface. This cylindrical surface is generated by a straight line called a generatrix, which moves in a given direction based on a closed curve called a directrix. In this example, the directrix corresponds to the profile of the cut section of the reinforcing beam 13 at the level of the connecting housing 15, and the generatrix is ​​parallel to the secondary direction Y. In other words, the connecting node 30 is entirely contained within the footprint of the connecting housing 15 of the structural profile 11. A variation of the invention with the connecting end 16 described above allows the connecting node 30 to be entirely contained within the footprint of the connecting housing 15.

[0097] Reference Figures 3 to 5 The connecting node 30 may have an external adhesive surface se30 on its outer side, and the reinforcing beam 13 may have an internal adhesive surface si13 on its inner side facing the external adhesive surface se30 of the connecting node 30. In that case, the assembly 10 may include an adhesive element 20 disposed between the external adhesive surface se30 and the internal adhesive surface si13. The adhesive element 20 is configured to bond the connecting node 30 to the reinforcing beam 13 at the level of the external adhesive surface se30 and the internal adhesive surface si13 when the reinforcing beam 13 is in the assembly configuration C2. Thus, the mechanical strength of the assembly 10 is greater when the reinforcing beam 13 is in the assembly configuration C2. Typically, the adhesive element may include an adhesive selected from epoxy resins, methyl methacrylates, acrylates, polyurethanes, silane-terminated polymers, or equivalents. Advantageously, the use of adhesive bonding allows the assembly 1 to be manufactured with a larger gap tolerance separating the reinforcing beam 13 from the structural profile 11 compared to conventional gap compensation methods such as welding.

[0098] Advantageously, when the reinforcing beam 13 is in the assembly configuration C2, the distance between the reinforcing beam 13 and the structural profile 11 is less than 10 mm, preferably less than 2 mm, and particularly approximately equal to 0 mm. In other words, when the reinforcing beam 13 is in the assembly configuration C2, the reinforcing beam 13 can contact or be close to the structural profile 11. It can be understood that the reinforcing beam 13 is configured to fit the length separating the two opposing structural profiles 11 of the frame 2.

[0099] According to one embodiment, when the reinforcing beam 13 is in assembly configuration C2, the distance between the reinforcing beam 13 and the structural profile 11 is less than 5 mm, preferably less than 1 mm. This allows for the fixation of the reinforcing beam 13 and the structural profile 11 without welding. Furthermore, using a smaller gap to assemble the reinforcing beam 13 and the structural profile 11 allows for better impact resistance. In practice, direct welding between the reinforcing beam 13 and the structural profile 11 would require stricter gap control and could potentially cause excessive constraint on the frame 2 structure.

[0100] Reference Figure 5 Component 10 may further include at least one fixing element 36, which is configured to allow the connection node 30 to be secured to the structural profile 11. This improves the mechanical strength of the connection between the structural profile 11 and the connection node 30. The at least one fixing element 36 is typically configured to allow reversible securing of the connection node 30 to the structural profile 11. Figure 5 One variation is illustrated, wherein the at least one fixing element 36 includes a bolt 37 configured to be secured to a blind rivet nut 38 disposed in the structural profile 11. The blind rivet nut may be placed within the inner wall of the structural profile 11. The blind rivet nut may be a sealing type. This bolted connection ensures proper support when the connection node 30 is subjected to shear loads. Alternatively, each bolt 37 may be connected to the structural profile 11 via a sealing element (such as a sealing ring) through a threaded hole arranged in the structural profile 11. Thus, the connection node 30 can be secured to the structural profile 11 while maintaining a seal.

[0101] The arrangement described above allows for the provision of an assembly 10 for the battery holder 1, in which a single battery can be directly bonded to the frame 2 of the battery holder 1. In effect, the insertion of the connection node 30 into the connection housing 15 allows for both a strong connection between the lateral structural profile 11 and the reinforcing beam 13, and an increase in battery packaging space without increasing the overall inner perimeter of the frame 2.
