[0050] New energy vehicles are exploring how to maximize the use of space in the vehicle so that more batteries can be arranged, thereby ensuring pure electric range and reducing mileage and charging anxiety. Generally, a battery assembly consists of battery cells / battery modules, battery assembly housings, and high and low voltage components such as BMS and BDU, as well as wiring harnesses. When assembled to a vehicle, related technologies usually design the battery assembly frame as a full frame in order to design components such as the battery assembly's output lines, which results in limited installation space for the battery assembly. Therefore, the present invention aims to provide a technical solution that can facilitate the design of components such as the battery assembly's output lines while ensuring integration and battery layout space.

[0051] Reference below Figure 1-Figure 7 The tray 1 , battery assembly 2 , vehicle frame 3 , vehicle body and vehicle according to an embodiment of the present invention are described.

[0052] In some embodiments, the tray 1 includes: a flat plate body 11, on which the battery cell / battery module 21 is arranged; a convex plate 12, which is protrudingly arranged on the flat plate body 11, and on which one or more of a wiring harness portion 123 and an explosion-proof valve 124 are arranged; wherein, along the first direction, the upper edge of the convex plate 12 is lower than the upper edge of the battery cell / battery module 21; the upper edge of the convex plate 12 is higher than the upper edge of the flat plate body 11.

[0053] Specifically, such as Figure 1As shown, the main portion of the tray 1 is a flat plate 11, typically used to house the battery cells / battery modules 21 of the battery assembly 2. A protruding plate 12 is provided on one side of the flat plate 11, and the wiring harness 123 of the battery assembly 2 is mounted on the protruding plate 12. It is understood that the battery assembly 2 typically contains high-voltage and low-voltage wiring harnesses, which are connected to the vehicle's power supply via connectors on the battery assembly 2. In other words, the battery assembly 2 is typically provided with connectors that connect to its internal wiring harnesses. In the embodiment of the present invention, the wiring harness 123 includes connectors. Because the vehicle body or frame 3 is often equipped with components such as crossbeams to ensure torsional rigidity, when the battery assembly 2 is mounted thereon, to avoid interference with the crossbeams, the frame of the tray 1 is often arranged parallel to the crossbeams along the length of the vehicle or along the height of the vehicle. This reduces the integration of the battery assembly 2 with the vehicle or sacrifices the maximum space available for the battery assembly 2 within the vehicle. Therefore, in this embodiment of the present invention, along the first direction, that is, the direction perpendicular to the straight plate body 11 of the tray 1, the upper edge of the protruding plate 12 is designed to be lower than the upper edge of the battery cell / battery module 21. When the battery assembly 2 is assembled on the vehicle, on the premise of being arranged in parallel with the crossbeam along the length direction, the lower height of the protruding plate 12 is utilized to achieve overlapping assembly with the crossbeam in the vehicle height direction. It can be understood that the edge area of ​​the straight plate body 11 of the tray 1 is directly connected to the lower surface of the frame 3. Compared with the full-frame tray 1 of the prior art, it avoids occupying space and can increase the capacity of the battery. A protruding plate 12 is provided on the straight plate body 11, and the wiring harness part 123 and the explosion-proof valve 124 are arranged on the protruding plate 12. The upper edge of the protruding plate 12 is designed to be lower than the upper edge of the battery cell / battery module 21, so as to facilitate the arrangement of the wires when the battery assembly 2 is installed in the vehicle. It should be explained that the battery assembly 2 usually has a front wire outlet part and a rear pressure wire outlet part, corresponding to the high-voltage connector and the low-voltage connector, such as Figure 1 As shown, there are two protruding plates 12, which are spaced apart in a direction perpendicular to the plate surface of the protruding plates 12. The wire outlet portion on the front protruding plate 12 is the front wire outlet portion, and the wire outlet portion on the rear protruding plate 12 is the rear wire outlet portion.

[0054] In some embodiments, a first flange 121 bent in a second direction is formed on the upper edge of the protruding plate 12 , and the first flange 121 is suitable for connecting with the vehicle body / frame 3 ; wherein the first direction intersects with the second direction.

[0055] Specifically, such as Figure 1 As shown, an embodiment of the present invention is designed with a first flange 121 bent in a second direction on the protruding plate 12, that is, a first flange 121 bent in a direction perpendicular to the plate surface of the protruding plate 12. The first flange 121 is used to assemble the upper cover 22 of the battery assembly 2 and the crossbeam of the vehicle, which helps to achieve sealing at the connection between the battery assembly 2 and the vehicle.

[0056] In some embodiments, along the first direction, the convex plate 12 includes an upper side bar and side side bars connected to the upper side bar, and the connection between the side side bar and the upper side bar is constructed as an arc-shaped connecting segment 122.

[0057] Specifically, such as Figure 1 As shown, the shape of the protruding plate 12 is a trapezoid that is narrow at the top and wide at the bottom. Along the first direction, that is, the direction perpendicular to the surface of the protruding plate 12, the protruding plate 12 includes an upper edge strip, that is, the upper surface of the first flange 121 referred to in the above embodiment, and a side edge strip of the protruding plate 12, that is, the side surface of the first flange 121. The connection between the upper surface and the side surface of the first flange 121 is an arc-shaped connecting section 122. It can be understood that the arc-shaped connecting section 122 is easier to seal than the right-angle connecting section.

[0058] In some embodiments, the tray 1 also includes at least two vertical plates 13 protruding from the flat plate body 11, and at least two vertical plates 13 are spaced apart along the third direction to form a first installation space, and the battery cell / battery module 21 is suitable for being arranged in the first installation space; the vertical plates 13 are suitable for being connected to the upper cover 22 / temperature averaging plate 23 of the battery assembly 2; the first direction intersects with the third direction.

[0059] Specifically, such as Figure 1-Figure 3 As shown, since the battery cell / battery module 21 is prone to outward expansion and deformation when impacted or in an unstable state, one embodiment of the present invention provides two vertical plates 13 protruding from the flat plate body 11 of the tray 1, spaced apart along a third direction. A first installation space is formed between the two vertical plates 13 to provide space for the battery cell / battery module 21. The third direction is also a direction parallel to the surface of the protruding plate 12. The temperature equalizing plate 23 of the battery assembly 2 is arranged above the battery cell / battery module 21, and the vertical plates 13 are connected to the temperature equalizing plate 23 of the battery assembly 2. When the temperature equalizing plate 23 of the battery assembly 2 is arranged below the battery cell / battery module 21, the vertical plates 13 are connected to the upper cover 22 of the battery assembly 82. The connection between the vertical plates 13 and the upper cover 22 or the temperature equalizing plate 23 restricts the outward expansion of the battery cell / battery module 21, thereby improving the anti-expansion reliability of the battery assembly 2.

[0060] In some embodiments, the vertical plate 13 is a hollow plate, and a plurality of cavities are formed in the vertical plate 13 .

[0061] Specifically, such as Figure 3 As shown, the interior of the vertical plate 13 is a hollow structure with multiple cavities formed therein. It can be understood that the energy absorption effect of the hollow plate is better than that of the solid plate.

[0062] In some embodiments, the tray 1 further includes a plurality of battery beams, which are spaced apart along the second direction on the flat plate body 11, and the battery beams and the vertical plates 13 together form a first installation space, and the battery cell / battery module 21 is suitable for being arranged in the first installation space; a smoke exhaust hole 14 is provided on the battery beams and / or the vertical plates 13, and an explosion-proof valve port 15 and an explosion-proof valve 124 are provided on the convex plate 12. When the explosion-proof valve 124 is opened, the smoke exhaust hole 14 is connected to the explosion-proof valve port 15; wherein, the first direction, the second direction and the third direction intersect.

[0063] Specifically, such as Figure 1-Figure 3 and Figure 5 As shown, the flat plate 11 of the tray 1 is provided with multiple battery cross beams spaced perpendicular to the surface of the protruding plate 12. The battery cross beams and the vertical plate 13 together form a first installation space, in which the battery cells / battery modules 21 and the like can be arranged. The battery cross beams enhance the strength of the battery assembly 2, provide a force transmission path for the vehicle, and prevent component damage during a collision. Furthermore, smoke exhaust holes 14 are provided on the battery cross beams and the vertical plate 13. Correspondingly, an explosion-proof valve port 15 is provided on the protruding plate 12. An openable and closable explosion-proof valve 124 is provided at the explosion-proof valve port 15. When the explosion-proof valve 124 is opened, the smoke exhaust hole 14 communicates with the explosion-proof valve port 15. That is, when the battery cells / battery modules 21 malfunction and emit smoke, the smoke in the first installation space is discharged from the battery assembly 2 through the smoke exhaust hole 14 and the explosion-proof valve port 15.

[0064] In some embodiments, the battery beams include a first battery beam 16, a second battery beam 17, and a third battery beam 18 spaced apart along the second direction; a front battery module is disposed between the first battery beam 16 and the second battery beam 17, and a rear battery module is disposed between the second battery beam 17 and the third battery beam 18; wherein the height of the third battery beam 18 is lower than that of the second battery beam 17.

[0065] Specifically, such as Figure 1 As shown, along a direction perpendicular to the surface of the convex plate 12, the flat plate body 11 of the tray 1 is spaced apart with a first battery beam 16, a second battery beam 17, and a third battery beam 18. A front battery module is disposed between the first and second battery beams 16, 17, and a rear battery module is disposed between the second and third battery beams 17, 18. The height of the third battery beam 18 is lower than that of the second battery beam 17. This embodiment of the present invention adopts a single-module isolation design. The front battery module is isolated by the vertical plate 13, the first battery beam 16, and the temperature plate 23. The rear battery module adopts an open semi-isolation design, that is, only one module of the dual-module battery assembly 2 is isolated. The single-module isolation design effectively achieves module isolation and improves the lightweight performance of the battery assembly 2.

[0066] A second aspect of the present invention provides a battery assembly 2 , comprising the tray 1 and a cell / battery module 21 as described in the above embodiment. The cell / battery module 21 is disposed on a flat plate 11 .

[0067] Specifically, such as Figure 2 and Figure 4 As shown, the battery cells / battery modules 21 are arranged on the flat plate 11 of the tray 1 to maximize the battery arrangement space.

[0068] In some embodiments, the battery assembly 2 also includes an upper cover 22, which is arranged on the tray 1 and is combined with the tray 1 to form the outer shell of the battery assembly 2; the upper cover 22 includes a top plate 221 and multiple side plates 222, and a first avoidance portion 2221 is formed on the side plate 222 for avoiding the protruding plate 12.

[0069] Specifically, such as Figure 2 As shown, the upper cover 22 of the battery assembly 2 is buckled on the tray 1, forming the outer shell of the battery assembly 2 and achieving the sealing of the battery cell / battery module 21 inside it; the upper cover 22 is composed of a top plate 221 and a side plate 222. A first avoidance portion 2221 is formed on the side plate 222 opposite to the protruding plate 12, that is, a notch is formed on the side plate 222. The shape of the notch is consistent with the shape of the protruding plate 12, which avoids the outlet of the battery assembly 2 and the explosion-proof valve 124. When the upper cover 22 is installed on the tray 1, it can be assembled tightly. It can be understood that, as in the above embodiment, the tray 1 has two protruding plates 12, which are spaced apart in a direction perpendicular to the plate surface of the protruding plates 12. The outlet portion on the front protruding plate 12 is the front outlet portion, and the outlet portion on the rear protruding plate 12 is the rear outlet portion. Therefore, the corresponding upper cover 22 of the battery assembly 2 is also provided with two first avoidance portions 2221.

[0070] In some embodiments, along the first direction, a distance D is defined between an upper edge of the protruding plate 12 and an upper edge of the cell / battery module 21 , where D satisfies the following relationship: 50 mm ≤ D ≤ 200 mm.

[0071] Specifically, along the direction perpendicular to the surface of the flat plate body 11, the distance between the upper edge of the protruding plate 12 and the upper edge of the battery cell / battery module 21 is D, and D satisfies: 50mm≤D≤200mm. Preferably, D can be, but is not limited to, any value within the range of 60mm-150mm.

[0072] In some embodiments, the tray 1 includes at least two vertical plates 13 protruding from the flat plate body 11, and at least two vertical plates 13 are spaced apart along a third direction to form a first installation space, and the battery cell / battery module 21 is suitable for being arranged in the first installation space; the battery assembly 2 also includes a temperature equalizing plate 23, which is connected to the vertical plate 13, and the temperature equalizing plate 23 is formed with a second flange 231 bent toward the tray 1, and the second flange 231 covers at least a portion of the plate surface of the vertical plate 13.

[0073] Specifically, such as Figure 1-Figure 3 As shown, two vertical plates 13 are protruding from the flat plate body 11 of the tray 1 and are spaced apart in a direction parallel to the surface of the convex plate 12. A first installation space is formed between the two vertical plates 13 to provide a layout space for the battery cell / battery module 21; the temperature equalizing plate 23 of the battery assembly 2 is arranged above the battery cell / battery module 21, and the vertical plate 13 is connected to the temperature equalizing plate 23 of the battery assembly 2. In order to firmly connect the vertical plate 13 with the temperature equalizing plate 23, an embodiment of the present invention is designed with a second flange 231 bent toward the tray 1 on the temperature equalizing plate 23, so that the second flange 231 covers part of the surface of the vertical plate 13, which can effectively avoid disconnection at the connection and better limit the outward expansion of the battery cell / battery assembly 2.

[0074] In some embodiments, a plurality of through holes 2311 are provided on the second flange 231 .

[0075] Specifically, such as Figure 3 As shown, a plurality of through holes 2311 are formed on the second flange 231 of the temperature equalizing plate 23 for assembling with the vertical plate 13 to realize the anti-expansion design of the battery assembly 2.

[0076] A third aspect of the present invention provides a frame 3 for a non-load-bearing vehicle, which is formed with a second installation space for installing the battery assembly 2 as described in the above embodiment; a second avoidance portion 33 is provided on the frame 3 for avoiding the convex plate 12.

[0077] Specifically, such as Figure 5 As shown, a frame 3 for a non-load-bearing vehicle is formed with a second installation space, and the battery assembly 2 of the above embodiment can be arranged in the second installation space. In addition, a second avoidance portion 33 is provided on the frame 3, which can avoid the protruding plate 12 on the tray 1.

[0078] In some embodiments, the vehicle frame 3 includes a left longitudinal beam, a right longitudinal beam, a front cross beam 31 and a rear cross beam 32 , which together form a second installation space.

[0079] Specifically, such as Figure 5 As shown, the second installation space is formed by the left longitudinal beam, the right longitudinal beam, the front cross beam 31 and the rear cross beam 32 of the frame 3. The front cross beam 31 and the rear cross beam 32 can effectively improve the torsional rigidity of the vehicle.

[0080] In some embodiments, the second avoidance portion 33 is formed on the front cross beam 31 and / or the rear cross beam 32 , and along the first direction, the upper surface of the protruding plate 12 is connected to the lower surface of the second avoidance portion 33 .

[0081] Specifically, such as Figure 1 、 Figure 5 and Figure 6 As shown, as in the tray 1 in the above embodiment, there are two protruding plates 12 thereon, which are spaced apart in a direction perpendicular to the plate surface of the protruding plate 12, and the wire outlet portion on the front protruding plate 12 is the front wire outlet portion, and the wire outlet portion on the rear protruding plate 12 is the rear wire outlet portion; therefore, in one embodiment of the present invention, the second avoidance portion 33 is formed on the front cross beam 31 and the rear cross beam 32, and the upper surface of the protruding plate 12 is connected to the lower surface of the second avoidance portion 33 in a direction perpendicular to the flat plate body 11, so that it can be overlapped with the front cross beam 31 and the rear cross beam 32; it can be understood that the edge area of ​​the flat plate body 11 of the tray 1 is directly connected to the lower surface of the frame 3, which avoids occupying space and further increases the capacity of the battery compared with the full-frame tray 1 in the prior art.
