Description

Technical Field

[0001] This disclosure relates to the technical field of vehicle structures, and more specifically to a mounting assembly for a battery pack for a vehicle and a vehicle including such a mounting assembly. Background Technology

[0002] With increasing global emphasis on environmental protection and sustainable development, the new energy vehicle industry has experienced rapid growth. The battery pack is a core component of electric or hybrid vehicles, and its reliability directly impacts safety and lifespan. Therefore, the battery pack needs to be securely fixed to the vehicle to withstand the complex operating conditions during driving.

[0003] Current battery pack mounting methods use fasteners (e.g., at the central part of the battery pack) to directly secure the battery pack to the vehicle floor. However, this mounting method lacks an effective buffering mechanism. When the vehicle accelerates or decelerates excessively (e.g., in a collision), the load is transferred directly through the vehicle floor to the fasteners, and then to the battery pack. This can easily lead to fastener breakage or even damage to the battery pack (e.g., casing damage, seal failure, or even cell short circuits and thermal runaway), affecting the safety of the vehicle and its occupants.

[0004] Therefore, there is an urgent need to propose a new battery pack fixing solution. Utility Model Content

[0005] The purpose of this disclosure is to provide a mounting assembly for a battery pack in a vehicle to overcome at least one of the aforementioned technical problems.

[0006] According to one aspect of this disclosure, a mounting assembly for a battery pack in a vehicle is provided. The vehicle includes a body floor, a beam member disposed vertically above the body floor, and a battery pack disposed below the body floor, a first surface of the beam member being opposed to and spaced apart from a second surface of the body floor in the vertical direction. The mounting assembly includes: a bracket including a first segment and a second segment, the first segment being fixed to the first surface of the beam member and the second segment being disposed against the second surface of the body floor; and a fastener extending from the battery pack through the body floor and fixedly connected to the second segment of the bracket to secure the battery pack; wherein the bracket is configured to deform as the fastener is displaced relative to the beam member in a first direction perpendicular to the vertical direction, such that the second segment follows the fastener in displaced relative to the first segment in the first direction.

[0007] In some embodiments, the support further includes a third segment that extends along the vertical direction and connects the first segment and the second segment.

[0008] In some embodiments, when viewed in a cross-section parallel to both the vertical direction and the first direction, the support is inverted V-shaped, wherein: the first segment includes a first wing and a second wing spaced apart from each other in the first direction, the first wing and the second wing each being fixed to the first surface of the beam member; and the third segment includes a first support wall and a second support wall that are opposite to and spaced apart from each other in the first direction, the first support wall extending along the vertical direction and connecting the first wing and the second segment, and the second support wall extending along the vertical direction and connecting the second wing and the second segment.

[0009] In some embodiments, when viewed in a cross-section parallel to both the vertical direction and the first direction, the support is I-shaped, wherein: the first segment includes a first end and a second end opposite to each other in the first direction, and a first intermediate portion extending between the first end and the second end; the second segment includes a third end and a fourth end opposite to each other in the first direction, and a second intermediate portion extending between the third end and the fourth end; and the third segment includes a third support wall that extends along the vertical direction and connects the first intermediate portion and the second intermediate portion.

[0010] In some embodiments, when viewed in a cross-section parallel to both the vertical direction and the first direction, the support is rectangular, wherein: the first segment includes a fifth end and a sixth end opposite to each other in the first direction; the second segment includes a seventh end and an eighth end opposite to each other in the first direction; and the third segment includes a fourth support wall and a fifth support wall opposite to each other and spaced apart in the first direction, the fourth support wall extending along the vertical direction and connecting the fifth end and the seventh end, and the fifth support wall extending along the vertical direction and connecting the sixth end and the eighth end.

[0011] In some embodiments, the beam member is a seat crossbeam of the vehicle and is fixedly connected to the vehicle body floor.

[0012] In some embodiments, the beam member defines a cavity recessed in the beam member along the second surface of the vehicle floor away from the vertical direction, and the first surface is the top surface of the cavity; and the second surface is a surface of the vehicle floor facing each other in the vertical direction with the top surface.

[0013] In some embodiments, the vehicle further defines a longitudinal direction and a lateral direction, the longitudinal direction, the lateral direction and the vertical direction being perpendicular to each other, and when the vehicle is on a horizontal surface, the longitudinal direction and the lateral direction are parallel to the horizontal surface, and the vertical direction is perpendicular to the horizontal surface, wherein the first direction is oriented in one of the following ways: (i) the first direction is parallel to the lateral direction; (ii) the first direction is parallel to the longitudinal direction; and (iii) the first direction is inclined relative to the longitudinal direction and the lateral direction.

[0014] In some embodiments, the first segment of the bracket is welded to the first surface of the beam member.

[0015] In some embodiments, the fastener is a bolt, and the second segment of the bracket has a threaded connection portion to which the bolt is fixed by a threaded connection.

[0016] In some embodiments, there is no mechanical connection between the second segment of the bracket and the vehicle floor.

[0017] In some embodiments, the battery pack is rectangular in shape and includes a central portion and a peripheral portion surrounding the central portion. The fastener extends vertically from the bottom side of the battery pack away from the vehicle floor, through the central portion to the top side of the battery pack opposite to the bottom side, and extends through the vehicle floor, and is fixedly connected to the second segment of the bracket.

[0018] According to another aspect of this disclosure, a vehicle is provided.

[0019] According to this disclosure, an effective cushioning mechanism can be provided while ensuring reliable fixation of the battery pack, thereby improving the safety of the battery pack. In other words, the fixing component according to this disclosure can balance the reliability and safety of battery pack fixation.

[0020] These techniques can be used alone or in any suitable combination. The foregoing summary is provided illustratively and is not intended to be restrictive. Attached Figure Description

[0033] Some embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. In the following embodiments, a mounting assembly for a battery pack in a passenger car is used as an example to illustrate the mounting assembly according to the present disclosure. It should be understood that such an example is not intended to limit the present disclosure. Rather, the mounting assembly according to the present disclosure, or variations thereof, is applicable to any other suitable type of vehicle. Furthermore, features in the various embodiments of the present disclosure can be combined with each other without conflict.

[0034] Figure 1 The chassis 2 of a vehicle 1 according to some embodiments of the present disclosure is schematically shown. Figures 2 to 4 The diagram schematically shows a portion of the chassis 2, which includes a body floor 3, two beam members 4 positioned above the body floor 3, a battery pack 5 positioned below the body floor 3, two sill beams 6 connected to the body floor 3, and a fixing assembly 7. Figure 4 The fixing component 7 includes a bracket 10 and a fastener 20. Figures 5A to 7B Details of these components are shown. It should be understood that, in addition to the chassis 2, the vehicle 1 may include any other suitable parts that enable its functionality. These parts are not shown and described in detail in this disclosure to avoid unnecessarily obscuring it. Furthermore, Figure 8 Is and Figure 9 Is with Figure 6 A similar schematic cross-sectional view is shown, and two variations of the fixing component 7 are illustrated respectively.

[0035] For clarity and conciseness, Figures 1 to 9The longitudinal direction X, lateral direction Y, and vertical direction Z of vehicle 1 are defined. The longitudinal direction X, lateral direction Y, and vertical direction Z are perpendicular to each other. The longitudinal direction X typically refers to the longitudinal or longitudinal direction of vehicle 1. The lateral direction Y typically refers to the lateral or width direction of vehicle 1. The longitudinal direction X and lateral direction Y together define a horizontal reference plane for vehicle 1. Alternatively, this horizontal reference plane can refer to a reference plane fixedly associated with the vehicle body, defined by the longitudinal and lateral axes of vehicle 1 when vehicle 1 is on a horizontal surface. When vehicle 1 is on a horizontal surface, this horizontal reference plane is parallel to the horizontal surface and perpendicular to the direction of gravity. As used in this disclosure, a horizontal surface refers to a flat reference plane located below vehicle 1, parallel to the horizontal reference plane of vehicle 1, and perpendicular to the direction of gravity. The vertical direction Z typically refers to the height direction of vehicle 1. When vehicle 1 is on a horizontal surface, the vertical direction Z is parallel to the direction of gravity and perpendicular to the horizontal surface. As shown in the figure, the arrow indicating the longitudinal direction X points from the front to the rear of vehicle 1, the arrow indicating the lateral direction Y points from the driver's side to the passenger side of vehicle 1, and the arrow indicating the vertical direction Z points in the opposite direction to gravity. It should be understood that this is merely illustrative and not intended to limit this disclosure. An exemplary configuration of vehicle 1 will now be described in detail with reference to the case where vehicle 1 is on a level surface.

[0036] like Figures 1 to 4 As shown, the chassis 2 of vehicle 1 may include a body floor 3, two beam members 4 disposed above the body floor 3 in the vertical direction Z, a battery pack 5 disposed below the body floor 3 in the vertical direction Z, two sill beams 6 connected to the body floor 3, and a fixing component 7.

[0037] The vehicle body floor 3 is the bottom load-bearing component of the vehicle 1 and can be a plate-like structure extending generally along both the longitudinal direction X and the lateral direction Y. The vehicle body floor 3 can form a support surface and component mounting surface for the bottom of the vehicle compartment, providing a fixed and load-bearing foundation for the beam component 4, sill beam 6, and battery pack 5, while also serving a space-dividing function. The vehicle body floor 3 has an upper surface 3a and a lower surface 3b that are opposite to each other in the vertical direction Z. When the vehicle 1 is on a horizontal ground, the lower surface 3b faces downwards and towards the horizontal ground, while the upper surface 3a is oriented opposite to the lower surface 3b and faces upwards. It should be understood that the configuration of the vehicle body floor 3 shown in the figures is merely illustrative, and this disclosure is not limited thereto.

[0038] The battery pack 5 is an energy storage component of the vehicle 1, and may be, for example, an integrated component including a battery module, a housing, a heat dissipation structure, and a connection interface. It should be understood that the configuration of the battery pack 5 shown in the figure is merely illustrative, and this disclosure is not limited thereto.

[0039] The sill beam 6 is a load-bearing structure located on the side of the vehicle body 1. Its main functions are to support the vehicle frame, separate the passenger compartment from the outside of the vehicle, and absorb collision energy and resist external load intrusion when the vehicle 1 experiences a side collision (i.e., along the lateral direction Y), thereby ensuring the safety of the occupants and the battery pack 5. Figure 2 and Figure 3 The diagram shows two sill beams 6 positioned on either side of the vehicle body floor 3 in the lateral direction Y. These two sill beams 6 may have a symmetrical structure about the longitudinal axis of the vehicle 1. The sill beams 6 may be fixedly connected to the vehicle body floor 3 and the beam member 4. It should be understood that the configuration of the sill beams 6 shown is merely illustrative, and this disclosure is not limited thereto.

[0040] The beam member 4 can be fixedly connected to the vehicle body floor 3, for example, and can be, for example, a seat crossbeam (two are shown here). The seat crossbeam is a strip-shaped member extending in the lateral direction Y, and can be rigidly connected to the vehicle body floor 3 by means of fixing such as welding and / or bolting. The seat crossbeam provides a fixed and load-bearing base for the seat. Figure 5A and Figure 6 As shown, beam member 4 can define a cavity 40 recessed into beam member 4 along the vertical direction Z away from vehicle floor 3. For example, beam member 4 can be stamped from a strip plate, and when viewed in a cross-section perpendicular to the lateral direction Y, beam member 4 can have a Z-shaped cross-section. Specifically, beam member 4 can include a top wall 41, a first side wall 42 and a second side wall 43 opposite to each other in the longitudinal direction X, and a first bottom wall 44 and a second bottom wall 45 extending from the first side wall 42 and the second side wall 43 along the longitudinal direction X, respectively. The first bottom wall 44 and the second bottom wall 45 extend opposite to each other. The top wall 41, the first side wall 42, the second side wall 43, the first bottom wall 44, and the second bottom wall 45 together form the Z-shaped profile. The cavity 40 is defined by the top wall 41, the first side wall 42, and the second side wall 43. The top wall 41 defines the top surface of the cavity 40. The first bottom wall 44 and the second bottom wall 45 are used to be fixedly connected to the upper surface 3a of the vehicle floor 3 by means such as welding and / or bolting.

[0041] like Figure 6 As best shown, the first surface of the beam member 4 and the second surface of the vehicle body floor 3 are opposite to and spaced apart from each other in the vertical direction Z. Here, the first surface of the beam member 4 is the top wall 41 of the beam member 4 (or, the top surface of the chamber 40), and the second surface of the vehicle body floor 3 is the upper surface 3a of the vehicle body floor 3. The configuration of the fixing assembly 7 according to this disclosure will be specifically described below with reference to the example of the first surface of the beam member 4 being the top wall 41 and the second surface of the vehicle body floor 3 being the upper surface 3a. It should be understood, and as will be specifically described below, that the first surface of the beam member 4 and the second surface of the vehicle body floor 3 are not limited thereto.

[0042] The fixing component 7 is configured to secure the battery pack 5 relative to the vehicle floor 3 and the beam member 4. Specifically, as follows: Figure 4 , Figure 5B and Figure 6 As shown, the fixing assembly 7 includes a bracket 10 and a fastener 20. The bracket 10 includes a first section 11 and a second section 12. The first section 11 is fixed to a first surface of one of the beam members 4 (in this embodiment, the top wall 41, or the top surface of the chamber 40), and the second section 12 is disposed against a second surface of the vehicle body floor 3 (in this embodiment, the upper surface 3a). That is, in the case of... Figure 6In the assembled state shown, the second segment 12 is positioned abutting against the second surface of the vehicle body floor 3. There is no mechanical connection between the second segment 12 of the bracket 10 and the vehicle body floor 3. The fastener 20 is shown as a bolt, and the configuration of the fixing assembly 7 according to this disclosure will be specifically described below with reference to the example of the fastener 20 being a bolt. The fastener 20 (here, a bolt) extends from the battery pack 5 through the vehicle body floor 3 and is fixedly connected to the second segment 12 of the bracket 10 to secure the battery pack 5 relative to the beam member 4 and the vehicle body floor 3. Thus, the fixing assembly 7 is able to hold the battery pack 5 in place relative to the vehicle body floor 3 and the beam member 4. Furthermore, the bracket 10 is configured to deform when the fastener 20 is displaced relative to the beam member 4 along a first direction 51 perpendicular to the vertical direction Z, so that the second segment 12 follows the fastener 20 in displacing relative to the first segment 11 along the first direction 51. In other words, when the fastener 20 is displaced relative to the beam member 4 along the first direction 51, the fastener 20 can cause the bracket 10 to deform so that the second segment 12 follows the fastener 20 in displacement along the first direction 51. In this embodiment, as shown, the first direction 51 may be parallel to the lateral direction Y and is indicated by a double-headed arrow, but it should be understood that this disclosure is not limited thereto. When the acceleration or deceleration of the vehicle 1 along the first direction 51 is too large (e.g., encountering a collision along the lateral direction Y), it will cause the beam member 4 and the vehicle floor 3 to displace relative to the battery pack 5 along the first direction 51, thereby causing the fastener 20 to displace relative to the beam member 4 along the first direction 51. Since the first segment 11 is fixed to the first surface of the beam member 4 and the second segment 12 abuts against the second surface of the vehicle floor 3, and since the bracket 10 can be deformed by the fastener 20 when the fastener 20 is displaced relative to the beam member 4 along the first direction 51, the second segment 12 can follow the fastener 20 in displacement relative to the first segment 11 along the first direction 51. This provides an effective cushioning mechanism for the fastener 20, reducing the shear force along the first direction 51 experienced by the fastener 20, thereby reducing or even eliminating the possibility of fastener 20 breaking, protecting the battery pack 5 from damage, and ensuring the safety of the occupants and vehicle 1. In other words, this configuration of the fixing component 7 provides an effective cushioning mechanism while ensuring reliable fixing of the battery pack 5, thus improving the safety of the battery pack 5. In other words, the fixing component 7 can balance the reliability and safety of the battery pack 5's fixing.

[0043] Furthermore, as described above, in this embodiment, the first surface of the beam member 4 is the top wall 41 and the second surface of the vehicle floor 3 is the upper surface 3a. That is, the first surface of the beam member 4 is the top surface of the chamber 40 (or, the top surface of the chamber 40), and the second surface of the vehicle floor 3 is the surface of the vehicle floor 3 that faces the top surface in the vertical direction Z, i.e., the upper surface 3a. This configuration maximizes the distance between the first surface of the beam member 4 and the second surface of the vehicle floor 3 along the vertical direction Z, thereby maximizing the range by which the second segment 12 can follow the fastener 20 to shift relative to the first segment 11 along the first direction 51. This improves the cushioning capacity of the fixing assembly 7, thereby further enhancing the safety of the battery pack 5.

[0044] like Figures 6 to 7B As shown, the bracket 10 may include a third segment 13. In some embodiments, as shown, the third segment 13 may extend along the vertical direction Z and connect the first segment 11 and the second segment 12. This configuration enables the bracket 10 to provide reliable positioning and support between the beam member 4 and the vehicle floor 3 along the vertical direction Z, thereby further improving the fixation reliability of the battery pack 5.

[0045] In some embodiments, such as Figures 6 to 7BAs shown, when viewed in a cross-section parallel to both the vertical direction Z and the first direction 51, the support 10 can be shaped like an inverted "V". Specifically, the first segment 11 of the support 10 may include a first wing 111 and a second wing 112 spaced apart from each other in the first direction 51. The first wing 111 and the second wing 112 are each fixed to a first surface of the beam member 4 (the top wall 41 in this embodiment). For example, the first wing 111 and the second wing 112 may be fixed to the top wall 41 of the beam member 4, for example, by welding. The third segment 13 of the support 10 may include a first support wall 131 and a second support wall 132 that are opposite to and spaced apart from each other in the first direction 51. The first support wall 131 extends along the vertical direction Z and connects the first wing 111 and the second segment 12, and the second support wall 132 extends along the vertical direction Z and connects the second wing 112 and the second segment 12. The first support wall 131 and the second support wall 132 can extend from the two opposite ends of the first wing 111 and the second wing 112 in the first direction 51, and extend to the two opposite ends of the second segment 12 in the first direction 51. The second segment 12 of the bracket 10 is arranged to abut against the second surface (upper surface 3a in this embodiment) of the vehicle floor 3. Furthermore, it is conceivable that the bracket 10 of the fixing assembly 7 can extend in this cross-sectional shape in a direction perpendicular to this cross-section (i.e., longitudinal direction X). The inverted V-shaped configuration of the bracket 10 can provide an effective cushioning mechanism while ensuring reliable fixation of the battery pack 5, thereby improving the safety of the battery pack 5. The bracket 10 can be made of metal material and formed by stamping and bending. Figure 6 As shown, when the fastener 20 is a bolt, the second section 12 of the bracket 10 has a threaded connection portion 12a. The bolt is fixed to the threaded connection portion 12a by means of a threaded connection.

[0046] In some embodiments, such as Figure 4 As shown, the battery pack 5 can be rectangular in shape and includes a central portion 52 and a peripheral portion 53 surrounding the central portion 52. As... Figure 2 and Figure 3As shown, the fastener 20 extends vertically in the Z direction from the bottom side 54 of the battery pack 5 opposite to the vehicle floor 3, through the central portion 52, to the top side 55 of the battery pack 5 opposite to the bottom side 54, and extends through the vehicle floor 3, and is fixedly connected to the second section 12 of the bracket 10. That is, the fixing component 7 secures the battery pack 5 to the beam member 4 at the central portion 52 of the battery pack 5. This fixing method improves the installation stability of the battery pack 5. It should be understood that this fixing method can be used alone or in combination with a method of fixing the battery pack 5 at the peripheral portion 53 of the battery pack 5. It should also be understood that this fixing method can also be implemented at the peripheral portion 53 of the battery pack 5 or at any other suitable location of the battery pack 5. Furthermore, it should be understood that the fastener 20 can also extend from the inside of the battery pack 5 (e.g., inside the housing) and extend through the vehicle floor 3 to be fixedly connected to the second section 12 of the bracket 10.

[0047] Figure 8 An optional type of fixing component is schematically shown. This optional type is... Figure 8 It is marked as fixed component 7'. Figure 8 The configuration of the fixed component 7' shown can be with Figures 2 to 7B The configuration of the fixed component 7 shown is basically the same. Therefore, in Figure 8 The same reference numerals are used to identify the same parts of the fixing component 7', and for the sake of brevity, the details of these same parts will not be described again.

[0048] Figure 8 The fixed component 7' shown is Figures 2 to 7B The difference in the fixing component 7 shown lies in the shape of the bracket 10. For example... Figure 8As shown, viewed in a cross-section parallel to both the vertical direction Z and the first direction 51, the bracket 10 of the fixing assembly 7' can be I-shaped. Specifically, the first segment 11 of the bracket 10 can include a first end 113 and a second end 114 opposite to each other in the first direction 51, and a first intermediate portion 115 extending between the first end 113 and the second end 114. The first segment 11 can extend along the first direction 51 and be fixed to the first surface of the beam member 4 (top wall 41 in this embodiment), for example, by welding. Similar to the first segment 11, the second segment 12 can include a third end 121 and a fourth end 122 opposite to each other in the first direction 51, and a second intermediate portion 123 extending between the third end 121 and the fourth end 122. The second segment 12 can extend along the first direction 51 and be arranged to abut against the second surface of the vehicle body floor 3 (upper surface 3a in this embodiment). The third segment 13 may include a third support wall 133, which extends along the vertical direction Z and connects the first intermediate portion 115 and the second intermediate portion 123. Furthermore, it is conceivable that the bracket 10 of the fixing assembly 7' can extend in the cross-sectional shape in a direction perpendicular to the cross-section (i.e., the longitudinal direction X). The I-beam configuration of the bracket 10 provides an effective cushioning mechanism while ensuring reliable fixation of the battery pack 5, thereby improving the safety of the battery pack 5. The bracket 10 may be made of a metallic material and formed by casting or welding. Similarly, in the case where the fastener 20 is a bolt, the second segment 12 of the bracket 10 has a threaded connection (not shown in the image). Figure 8 (Pointed out). Bolts are fixed to the threaded connection in a threaded manner. For example, for each I-shaped bracket 10, two threaded connections can be provided on the second intermediate portion 123 of the second section 12, and one threaded connection is provided on each side of the connection between the second intermediate portion 123 and the third support wall 133, and two bolts are provided to fix to these two threaded connections respectively, thereby enhancing the fixation of the battery pack 5.

[0049] Figure 9 This schematically illustrates another optional type of the fixing component. This optional type... Figure 9 It is marked as a fixed component 7''. Figure 9 The configuration of the fixed component 7'' shown can be with Figures 2 to 7B The configuration of the fixed component 7 shown is basically the same. Therefore, in Figure 9 The same reference numerals are used to identify the same parts of the fixing component 7'', and for the sake of brevity, the details of these same parts will not be described again.

[0050] Figure 9 The fixed component 7'' shown is with Figures 2 to 7B The difference in the fixing component 7 shown lies in the shape of the bracket 10. For example... Figure 9 As shown, viewed in a cross-section parallel to both the vertical direction Z and the first direction 51, the bracket 10 of the fixing component 7'' can be rectangular. Rectangular refers to a square or rectangular frame shape. Specifically, the first segment 11 of the bracket 10 can include a fifth end 116 and a sixth end 117 opposite to each other in the first direction 51. The first segment 11 can extend along the first direction 51 and be fixed to the first surface of the beam member 4 (top wall 41 in this embodiment), for example, by welding. Similar to the first segment 11, the second segment 12 can include a seventh end 124 and an eighth end 125 opposite to each other in the first direction 51. The second segment 12 can extend along the first direction 51 and be positioned to abut against the second surface of the vehicle floor 3 (upper surface 3a in this embodiment). The third segment 13 can include a fourth support wall 134 and a fifth support wall 135 opposite to each other and spaced apart in the first direction 51. The fourth support wall 134 extends along the vertical direction Z and connects the fifth end 116 and the seventh end 124, and the second support wall 132 extends along the vertical direction Z and connects the sixth end 117 and the eighth end 125. Furthermore, it is conceivable that the bracket 10 of the fixing assembly 7'' can extend in the cross-sectional shape in a direction perpendicular to the cross-section (i.e., the longitudinal direction X). The box-shaped configuration of the bracket 10 provides an effective cushioning mechanism while ensuring reliable fixation of the battery pack 5, thereby improving the safety of the battery pack 5. The bracket 10 can be made of metallic material and formed by casting, bending, or welding. Similarly, in the case where the fastener 20 is a bolt, the second segment 12 of the bracket 10 has a threaded connection (not shown in the image). Figure 9 (Pointed out). Bolts are fixed to the threaded connection by means of threaded connection.

[0051] Although the foregoing description of the configuration of fixing components 7, 7', and 7'' is based on the example of beam member 4 being a seat crossbeam, it should be understood that this disclosure is not limited thereto. In other embodiments, beam member 4 may be any suitable beam, such as any suitable beam fixed to the vehicle floor 3, and may extend in any suitable direction (e.g., lateral direction Y, longitudinal direction X, or any suitable direction inclined relative to the horizontal reference plane and lateral direction Y and longitudinal direction X), and may have any suitable cross-sectional shape.

[0052] Although the foregoing description of the configuration of fixing components 7, 7', and 7'' is based on the example of the first surface of beam member 4 being the top wall 41 and the second surface of vehicle floor 3 being the upper surface 3a, it should be understood that this disclosure is not limited thereto. In other embodiments, the first surface of beam member 4 and the second surface of vehicle floor 3 can be any suitable surface or portion of beam member 4 and vehicle floor 3 that are opposite and spaced apart from each other in the vertical direction Z, as long as they allow the first segment 11 of bracket 10 to be fixed to beam member 4 and the second segment 12 to be disposed against vehicle floor 3.

[0053] Although the foregoing description of the configuration of fastening components 7, 7', and 7'' is based on the example of fastener 20 being a bolt, it should be understood that this disclosure is not limited thereto. In other embodiments, fastener 20 may be a snap-fit, a riveted fastener, or any other suitable fastener, and the second segment 12 of bracket 10 may be modified accordingly to mate with fastener 20, thereby allowing fastener 20 to be securely connected to the second segment 12.

[0054] Although the foregoing description specifically illustrates the configuration of the fixing components 7, 7', and 7'' using the example of the first segment 11 of the bracket 10 being welded to the first surface of the beam member 4, it should be understood that this disclosure is not limited thereto. In other embodiments, the first segment 11 of the bracket 10 may also be fixed to the first surface of the beam member 4 by riveting, snap-fitting, adhesive bonding, bolting, or any other suitable means.

[0055] Although the foregoing description of the configuration of the fixing components 7, 7', and 7'' is based on the example of the first direction 51 being parallel to the lateral direction Y, it should be understood that this disclosure is not limited thereto. In other embodiments, the first direction 51 can be any suitable direction perpendicular to the vertical direction Z. Specifically, the first direction 51 can be perpendicular to the vertical direction Z and simultaneously be oriented in one of the following ways: (i) the first direction 51 is parallel to the lateral direction Y; (ii) the first direction 51 is parallel to the longitudinal direction X; and (iii) the first direction 51 is inclined relative to both the longitudinal direction X and the lateral direction Y (i.e., intersecting with both the longitudinal direction X and the lateral direction Y). In the first case, the fixing components 7, 7', and 7'' are particularly adapted to act as a buffer in the event of a collision involving the vehicle 1 along the longitudinal direction X, thereby protecting the battery pack 5. In the second case, the fixing components 7, 7', and 7'' are particularly adapted to act as a buffer in the event of a collision involving the vehicle 1 along the lateral direction Y, thereby protecting the battery pack 5. In the third case, the fixing components 7, 7', and 7'' are particularly suitable for acting as a buffer in the event of an oblique collision with vehicle 1, thereby protecting the battery pack 5. It should also be understood that fixing components acting as buffers in different directions can be present simultaneously in the same vehicle.
