As mentioned in the background section above, the present inventors have realized that there is room for improvement in the prior art battery pack solutions for achieving torsional force isolation. There is a need for a battery pack assembly and a motor vehicle that achieve better battery pack connection strength, provide better support for the battery cells, and improve the overall structural stability of the battery pack, thereby improving user satisfaction. Based on these problems and room for improvement in the art, the inventors of the present application have provided, in one or more embodiments, a battery pack assembly and a motor vehicle, which are believed to solve one or more of the problems in the prior art.

First, FIG. 1 presents a schematic view of a vehicle 10 including a battery pack assembly 100 according to one or more embodiments of the utility model. It should be appreciated that in the context of the present utility model, a vehicle 10 embodying the present utility model may refer to any vehicle that includes a battery pack assembly, and may include, for example, but not limited to, fossil fuel vehicles, electric vehicles (such as a plug-in hybrid electric vehicle (PHEV), full Hybrid Electric Vehicle (FHEV), mild Hybrid Electric Vehicle (MHEV), or Battery Electric Vehicle (BEV), etc.), and may even include marine vessels, aircraft, etc. The vehicle 10 may include mobility-related components such as an engine, electric motor, transmission, suspension, drive shaft, wheels, and/or the like. The vehicle 10 may be non-autonomous, semi-autonomous (e.g., some conventional locomotion functions are autonomously controlled by the vehicle) or autonomous (e.g., locomotion functions are autonomously controlled by the vehicle, without direct input from a user).

In view of the foregoing background, and referring to fig. 2-16, an aspect of the present utility model provides a battery pack assembly 100, which includes a battery support bracket 104, a battery pack 106, a support connection 108, and a buffer 110. Wherein the battery support bracket 104 is configured to be coupled to a vehicle body, which in one embodiment may be coupled to the frame 102, for example. The battery support rack 104 supports the battery packs 106, for example, the battery packs 106 may be supported above the battery support rack 104, although this is not precluded from being supported either laterally or below the battery support rack 104 in some battery configurations. The battery pack 106 further includes a battery array 112, a first beam 114, and a second beam 116, with particular reference to fig. 6, 7, and 8. The first beam 114 and the second beam 116 are angled with respect to each other, such as at 90 degrees from each other, although other angles, such as greater or less than 90 degrees, may be employed depending on the different battery pack configuration; and the first beam 114 and the second beam 116 together support the battery array 112, with particular reference to fig. 4 and 5. The support connection 108 extends into and is secured to the first beam 114 and/or the second beam 116. In the depicted embodiment, the first beam 114 is configured as a plurality of cross beams and/or battery tray lateral frames extending along the vehicle lateral direction X in the installed position, while the second beam 116 forms a battery tray longitudinal frame, it being understood that there may be a plurality of second beams 116, for example extending along the vehicle longitudinal direction Y in a mid-package position. In one or more embodiments, the first beam 114 and the second beam 116 may be configured as a frame or tray edge surrounding the battery array. The support connection 108 is illustrated as being secured to the first beam 114, but it should be understood that the support connection 108 could equally be secured to the second beam 116, or both the first beam 114 and the second beam 116. The buffer 110 is connected to both the support connection 108 and the battery support bracket 104 and spaces the battery pack 106 from the battery support bracket 104, with particular reference to fig. 2, 3 and 4, that is, the buffer 110 provides a gap between the battery pack 106 and the battery support bracket 10. In one or more embodiments, the battery support bracket 104 has a support fixture 170 corresponding to the first beam 114 and/or the second beam 116 described above in the installed position, see fig. 2, the support fixture 170 being used to fixedly connect the first beam 114 and/or the second beam 116 via the bumper 110, thereby connecting the battery pack to the battery support bracket 104. The battery support bracket 104 may include only a skeleton constituted by the support fixtures 170, and may also include a shielding layer 172 between the skeletons, as shown in fig. 3, wherein the support fixtures 170 are configured to have a reinforced structure.

In the embodiment shown in the drawings, the first beam 114 may extend in a transverse direction X and the second beam 116 may extend in a longitudinal direction Y, see fig. 8. The battery support bracket 104 may be attached to the underside of the frame 102, such as by fasteners or welding, such that the battery pack 106 is disposed between the two stringers of the frame 102 and spaced apart from the frame 102 to isolate the torsional forces experienced by the vehicle body. It will be appreciated by those skilled in the art that the foregoing orientation and positional relationship may be varied and adjusted depending upon the configuration of the battery pack without affecting the scope of the present disclosure.

In the context of the present utility model, the directional expressions "lateral direction X", "longitudinal direction Y", "vertical direction", "above", "below", "front", "rear", "side", "top side", and "bottom side", etc., mentioned in the foregoing and in the following disclosure, relate to the battery pack assembly 100 in the mounted state and the vehicle 10 to which it is mounted, for example, the "lateral direction X" may generally correspond to the left-right direction of the vehicle 10 to which the battery pack assembly 100 is mounted, or the lateral direction of the vehicle; the "longitudinal direction Y" may generally correspond to the fore-aft direction of the vehicle 10, and so on. Further, the battery array 112 in the battery pack 106 of the battery pack assembly 100 may be of a single-layer structure, a multi-layer structure, or a partially-positioned single-layer, partially-positioned multi-layer structure as shown in the drawings, which may be adjusted according to the specific battery pack structure.

In the embodiment of the present utility model, the above-described structural features enable better connection strength of the battery pack 106 with the battery support frame 10 and provide better supporting force for the battery cells, further improving overall structural stability of the battery pack, and thus improving user satisfaction, by providing the support connection 108 and extending the support connection 108 into and securing the first beam 114 and/or the second beam 116 for supporting the battery array 112, and connecting and isolating the buffer 110 from both the support connection 108 and the battery support frame 104.

Referring next to fig. 8 and 11, the battery pack 106 further includes a cooling plate 130 and a bottom plate 132 according to some embodiments of the utility model. The cooling plate 130 is used to provide heat dissipation for the battery array 112 within the battery pack 106, and fluid lines may be included within the cooling plate 130 for the passage of cooling fluid to carry away heat generated by the battery array 112 during operation. The bottom plate 132 is positioned below the cooling plate 130 and provides some protection to the cooling plate 130 and the battery array 112. The support connection 108 may include a post 134, a flange 136, and a tab 138. The flange 136 surrounds the cylindrical portion 134 and extends radially from the cylindrical portion 134. In the installed state, the flange 136 is disposed between the base plate 132 and the cooling plate 130. The tab 138 is removably attached, such as by threading, to the post 134 and clamps the base plate 132 between the tab 138 itself and the flange 136, as shown in FIGS. 11 and 12. In this structure, the flange 136 and the connection piece 138 are provided, and the bottom plate 132 and the cooling plate 130 are clamped in layers by the flange 136 and the connection piece 138, so that the stability of the whole structure is better and the tightness is better. In some further embodiments of the present utility model, a bumper 174 may be provided between the cooling plate 130 and the bottom plate 132, shown in phantom in fig. 7, to avoid the cooling plate 130 and the bottom plate 132 from colliding with each other during movement of the vehicle 10, thereby improving the NVH (noise, vibration, harshness) performance of the battery pack as a whole and providing further protection for the cooling plate 130 and the battery array 112.

Further, the base plate 132 may include a plurality of reinforcing structures 176 thereon, and as shown in fig. 7, a unit of the reinforcing structures 176 may take the shape of four elliptical lobes around a cross lobe, with the reinforcing structures 176 including, for example and without limitation, a protrusion formed by stamping on the base plate 132. Of course, two or three elliptical protrusions may take the shape of surrounding the T-shaped protrusion depending on the position. This structure may further enhance the protective effect of the bottom plate 132 on the internal cooling plate 130 and the battery array 112.

Referring now to fig. 11, in several embodiments of the present utility model, the battery assembly 100 further includes a first seal 140 and a second seal 142, the first seal 140 being disposed between the base plate 132 and the flange 136 and surrounding the post 134, and the second seal 142 being disposed between the cooling plate 130 and the flange 136 and surrounding the post 134. The flange 136 of the support connection 108 includes a first groove 144 and a second groove 146, the first seal 140 being disposed within the first groove 144 and the second seal 142 being disposed within the second groove 146. In this structure, by providing the first sealing ring 140 and the second sealing ring 142, and the first groove 144 and the second groove 146, the space inside the cooling plate 130 and between the cooling plate 130 and the bottom plate 132 is independently closed, providing a better and more stable sealing effect for the position where the support connection 108 penetrates.

With continued reference to fig. 11, in some embodiments of the utility model, the support connection 108 includes a first connection 118 and a second connection 120, and is secured to the first beam 114 and/or the second beam 116 by both the first connection 118 and the second connection 120. By providing two connection points, first connection 118 and second connection 120, support connection 108 may be more firmly coupled to first beam 114 and/or second beam 116, improving the overall structural stability of battery pack assembly 100.

Further, as can be seen in fig. 10 and 11, in several embodiments of the present utility model, the first connection 118 is located at an end of the support connection 108 in a first direction and the second connection 120 is located at a side of the support connection 108 in a second direction, wherein the first direction has a first angle with respect to the second direction. The first direction may be, for example, a vertical direction and the second direction may be, for example, a longitudinal direction of the vehicle, and it will be appreciated by those skilled in the art that other directions may be adopted depending on the battery configuration, so long as the first angle formed is not 0 degrees or 180 degrees. In this configuration, the placement of the first connection portion 118 at the first directional end of the support connection portion 108 and the placement of the second connection portion 120 at the second directional side of the support connection portion 108 may first be secured in place at the first connection portion 118 during assembly, thereby allowing the support connection portion 108 to compress the bottom structure (e.g., cooling plate 130) of the battery pack 106, followed by the location of the second connection portion 120, which provides for better positional accuracy and tightness of the components. In a further embodiment of the present utility model, at least three connection points of the first and second connection portions 118 and 120 form a triangle in a section along the first direction, see fig. 11, thereby further enhancing structural stability.

As shown in fig. 11, in the embodiment including the first seal ring 140 and the second seal ring 142, the first connection portion 118 is connected to compress the second seal ring 142 between the cooling plate 130 and the flange 136, and the first seal ring 140 is compressed between the bottom plate 132 and the flange 136 via the connection piece 138, so that the second connection portion 120 is connected with better tightness between the components, and the position accuracy and tightness are further improved.

Referring back to fig. 9, 10 and 11, in some embodiments of the utility model, the first connection 118 includes a fastener 122, and the first beam 114 and/or the second beam 116 (here first beam 114 is exemplified) includes opposing first and second sidewalls 126, 128, with the second connection 120 being welded to both the first and second sidewalls 126, 128. In this configuration, the first attachment portion 118 is secured in place by the fastener 122, allowing the support attachment portion 108 to compress the bottom structure of the battery pack 106 (e.g., the cooling plate 130) to a suitable degree, further improving the sealing; and the second connection 120 of the support connection 108 is connected to the first beam 114 and/or the second beam 116 by opposite sidewalls, making the connection of the support connection 108 more stable and stressed more uniform, improving structural stability.

With continued reference to fig. 9, 10 and 11, in several further embodiments of the present utility model, the first and second sidewalls 126 and 128 include third and fourth openings 158 and 160, respectively, and the second connection 120 is welded to both the first and second sidewalls 126 and 128 through the third and fourth openings 158 and 160. In this structure, the third and fourth openings 158 and 160 are provided on the first and second sidewalls 126 and 128, respectively, which provides a convenient operating position for welding the second connection portion 120 of the support connection portion 108, thereby improving production assembly efficiency.

Referring to fig. 10 and 11, according to some embodiments of the present disclosure, the first beam 114 and/or the second beam 116 (here, the first beam 114 is exemplified) further includes a top wall 148 and ribs 150 located inside. The top wall 148 has a first opening 152 and the rib 150 has a second opening 154 aligned with the first opening 152. The first opening 152 serves as a relief opening during installation, and the fastener 122 connects the first connection 118 to the rib 150 through the second opening 154. The battery pack 106 also includes a closure 156, such as, but not limited to, a rubber closure, for closing the first opening 152, see fig. 10. By providing the first opening 152 and the closure member 156, metal chips generated during processing and welding can be enclosed inside the beam from contacting the battery array 112. To further enhance the foregoing, in several other embodiments, a closure or seal cap similar to closure 156 described above may be provided at each opening or aperture machined into first beam 114 and/or second beam 116 to enclose the metal chips created during machining and welding within the beam to avoid contact with cell array 112.

Referring to fig. 11, according to some embodiments of the present utility model, the post 134 includes a first connection hole 162 that extends axially. The bumper 110 includes a first rigid connection 164, a second rigid connection 166, and a flexible connection 168. The flexible connection 168 connects and spaces apart both the first rigid connection 164 and the second rigid connection 166. The first rigid connection 164 is connected to the battery support bracket 104 and the second rigid connection 166 is connected to the first connection hole 162, such as by fasteners. The torsion force experienced by the vehicle body can be separated from the battery pack 106 by providing the buffer 110, and the connection with the first connection hole 162 through the second rigid connection portion 166 provides better connection force and stability.

Referring now to fig. 13, at a side frame location of the battery pack 106, such as a rear side frame, the first beam 114 may have a generally L-shaped cross-sectional shape, where a second support connection 178 may be provided, the second support connection 178 extending upwardly through a horizontally extending portion of the L-shape and including an end connection 180 at the top. The end connection 180 may be connected to the frame by, for example, fastening nuts 182, thereby allowing the second support connection 178 to compress the bottom structure of the battery pack 106 (e.g., the cooling plate 130) to an appropriate degree to enhance sealability. Other configurations and shape arrangements of the second support link 178 can be referred to the support link 108 described above, and will not be described in detail herein.

Referring now to fig. 14, a first seal 184 and a second seal 186 may be provided at the edge of the battery pack 106, the first seal 184 being located between the base plate 132 and the cooling plate 130, the second seal 186 being located between the cooling plate 130 and the battery pack frame (which may be the first beam 114 or the second beam 116). The first and second sealing structures 184, 186 may include, but are not limited to, rubber seals or foam seals, etc. The first seal 184 and the second seal 186 may be located in the inboard direction of the battery pack of peripheral fasteners (e.g., bolts 188 and blind rivet nuts 192, stream drill screws 190, etc.). This structure can provide the battery pack 106 with better sealing performance as a whole.

With further reference to fig. 14 and 15, a number of peripheral fasteners may be provided between the first and second seal structures 184, 186 and the edges of the battery pack 106, including bolts 188 and blind rivet nuts 192, flow drilling screws 190, and the like. In this position, a sealant layer 194 may be provided between the cooling plate 130 and the battery pack frame (which may be the first beam 114 or the second beam 116) to further improve sealability. The blind rivet nut 192 is secured to the battery pack frame (which may be the first beam 114 or the second beam 116), and the bolt 188 is attached to the blind rivet nut 192 through the base plate 132, where the cooling plate 130 may form a relief notch 196. The stream drill screws 190 may be secured to the battery pack frame (which may be the first beam 114 or the second beam 116) through only the cooling plate 130. In this structure, better connection performance and sealing can be achieved by the staggered fit of the two connection modes.

Referring finally to fig. 6 and 16, a grounding member 198 is provided on the battery pack frame (which may be either the first beam 114 or the second beam 116). The ground member 198 may be T-shaped in cross-section and have holes for ground wires to pass through, as shown in fig. 16, and the outer perimeter of the ground member 198 may be attached to the frame of the battery pack by welding (e.g., inert gas welding) to form-fit openings therein to provide better sealing.
