[0021] The following is based on the appendix Figure 1-4 Further explanation of this utility model:

[0022] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figures 1-3As shown, the first embodiment of this utility model provides a battery tray assembly based on the prior art, including: a tray frame 10, the tray frame 10 including a first frame connecting rod 104, a second frame connecting rod 105, a third frame connecting rod 106 and a frame connecting assembly connected in series, the third frame connecting rod 106 being parallel to and spaced apart from the first frame connecting rod 104, and the frame connecting assembly being spaced apart from the second frame connecting rod 105; a liquid cooling plate 30, the liquid cooling plate 30 having a cooling channel 301, the liquid cooling plate 30 being connected to the tray frame 10; and a support frame 20, the support frame 20 including at least one cross connecting bracket 201 and at least two support rods 202, the first ends of the two support rods 202 being connected to the first frame. One of the first frame connecting rod 104 and the third frame connecting rod 106 abuts against each other. The second end of each of the two support rods 202 abuts against the other of the first frame connecting rod 104 and the third frame connecting rod 106. The two support rods 202 are spaced apart. A cross connecting frame 201 is disposed between the two support rods 202. The first end of the cross connecting frame 201 abuts against one of the first frame connecting rod 104 and the third frame connecting rod 106. The second end of the cross connecting frame 201 abuts against the other of the first frame connecting rod 104 and the third frame connecting rod 106. The third end of the cross connecting frame 201 abuts against one of the two support rods 202. The fourth end of the cross connecting frame 201 abuts against the other of the two support rods 202.

[0026] Applying the technical solution of this embodiment, the tray frame 10 forms a stable foundation through a first frame connecting rod 104, a second frame connecting rod 105, a third frame connecting rod 106, and a frame connecting assembly connected in series. The third frame connecting rod 106 is arranged parallel to and spaced apart from the first frame connecting rod 104, and the frame connecting assembly is arranged spaced apart from the second frame connecting rod 105. This, combined with the layout of at least one cross connecting frame 201 and at least two support rods 202 in the support frame 20—the two support rods 202 abut against the first frame connecting rod 104 and the third frame connecting rod 106 at their ends and are spaced apart, and the cross connecting frame 201 is placed between the two support rods 202 with its four ends abutting against the first frame connecting rod 104, the third frame connecting rod 106, and the two support rods 202, respectively—significantly improves the stability and support strength of the overall structure. At the same time, the liquid cooling plate 30 is connected to the tray frame 10 through its own cooling channel 301, which can efficiently dissipate battery heat, taking into account both structural stability and heat dissipation performance.

[0027] Furthermore, the battery tray assembly also includes: a plurality of circumferential mounting beams 40, which are circumferentially spaced on the outside of the tray frame 10 and connected to the tray frame 10 respectively. The circumferential mounting beams 40 are also spaced apart from the liquid cooling plate 30 and the support frame 20. By adding multiple circumferential mounting beams 40, which are circumferentially spaced on the outside of the tray frame 10 and connected to it respectively, and spaced apart from the liquid cooling plate 30 and the support frame 20, not only is the overall structural strength and circumferential support stability of the tray frame 10 increased, providing a more reliable installation and fixing structure for the battery tray assembly, but also mutual interference with the liquid cooling plate 30 and the support frame 20 is effectively avoided, ensuring that each component functions independently and improving the overall structural rationality and operational reliability of the assembly.

[0028] In one exemplary embodiment, the frame connection assembly includes: a fourth frame connecting rod 101, which is spaced apart from the support frame 20 and the second frame connecting rod 105, with a first end connected to one end of a third frame connecting rod 106, and the fourth frame connecting rod 101 connected to a portion of the peripheral mounting beam 40; a fifth frame connecting rod 102, which is spaced apart from the support frame 20 and the second frame connecting rod 105, with a first end connected to the second end of the fourth frame connecting rod 101, and the fifth frame connecting rod 102 connected to a portion of the peripheral mounting beam 40; and a sixth frame connecting rod 103, which is spaced apart from the support frame 20 and the second frame connecting rod 105, with a first end connected to the second end of the fifth frame connecting rod 102, the second end of the sixth frame connecting rod 103 connected to one end of a first frame connecting rod 104, and the sixth frame connecting rod 103 connected to a portion of the peripheral mounting beam 40.

[0029] In this embodiment, a complete structure is formed by sequentially connecting the fourth frame connecting rod 101, the fifth frame connecting rod 102, and the sixth frame connecting rod 103. The first end of the fourth frame connecting rod 101 is connected to one end of the third frame connecting rod 106 and is spaced apart from the support frame 20 and the second frame connecting rod 105, connecting a portion of the perimeter hanging beam 40. The first end of the fifth frame connecting rod 102 is connected to the second end of the fourth frame connecting rod 101 and is also spaced apart from the support frame 20 and the second frame connecting rod 105, connecting a portion of the perimeter hanging beam 40. Both ends of the sixth frame connecting rod 103 are connected to the second end of the fifth frame connecting rod 102 and one end of the first frame connecting rod 104, respectively, maintaining a spaced distance and connecting a portion of the perimeter hanging beam 40. This layout enhances the overall connection strength and structural stability of the pallet frame 10, avoids mutual interference between components through the spaced arrangement with the support frame 20 and the second frame connecting rod 105, and further improves the overall load-bearing capacity and reliability of the structure in conjunction with the perimeter hanging beam 40.

[0030] In this embodiment, as Figure 4 As shown, the edge profile of at least one of the first frame connecting rod 104, the second frame connecting rod 105, the third frame connecting rod 106, the fourth frame connecting rod 101, the fifth frame connecting rod 102, and the sixth frame connecting rod 103 includes a first straight segment and a second straight segment, which are interlocked. By adopting the design of the first straight segment and the second straight segment interlocking, the structural strength and deformation resistance of the corresponding frame connecting rods can be enhanced. Simultaneously, the interlocking structure facilitates precise docking and stable connection between the frame connecting rods or with other components, improving overall assembly accuracy and structural stability. It also provides a more reasonable transition method for combining different materials or structural parts, helping to optimize the overall mechanical property distribution of the frame.

[0031] Furthermore, the first straight segment includes: a first component segment 603, which connects to the second straight segment; a second component segment 605, which is adjacent to the first component segment 603; and a third component segment 607, which is spaced apart from the first component segment 603, adjacent to the second component segment 605, and connected to the second straight segment; wherein adjacent component segments are connected by a circular arc transition. This segmented design, combined with the circular arc transition, not only enhances the structural strength and bending resistance of the frame connecting rod edges through the multi-segment structure, but also disperses stress concentration through the circular arc transition, avoiding structural damage caused by excessive local stress. Furthermore, it optimizes the fitting effect between each component segment and the second straight segment, improving the overall connection stability and assembly compatibility.

[0032] Further, the second straight segment includes: a fourth component segment 608, which is spaced apart from the second component segment 605 and the first component segment 603, and connected to the third component segment 607; a fifth component segment 601, which is adjacent to the fourth component segment 608, parallel to the first component segment 603, and spaced apart from the second component segment 605 and the first component segment 603; and a sixth component segment 602, which is adjacent to the fifth component segment 601, and connected to the fourth component segment 607. Segment 608, the third segment 607, and the second segment 605 are spaced apart; the sixth segment 602 is connected to the first segment 603; the seventh segment 604 is adjacent to the sixth segment 602 and parallel to the first segment 603, positioned between the fifth segment 601 and the first segment 603; the eighth segment 606 is adjacent to the seventh segment 604 and connected to the third segment 607; adjacent segments are connected by a rounded transition. This multi-segment layout, combined with the rounded transition design, not only achieves precise fitting with the segments of the first straight segment, enhancing the structural integrity and connection strength of the overall edge profile, but also distributes stress through reasonable spacing and parallel arrangement, avoiding stress concentration with the rounded transition, further improving the deformation resistance and structural stability of the frame connecting rods, while optimizing assembly compatibility with other components.

[0033] In this embodiment, the battery tray assembly further includes: a plurality of plug-in components 50, which are circumferentially spaced on the outside of the tray frame 10. The plurality of plug-in components 50 are connected to the tray frame 10 respectively. The plug-in components 50 are spaced apart from the circumferential mounting beam 40, the liquid cooling plate 30 and the support frame 20 respectively. At least one circumferential mounting beam 40 is provided between two adjacent plug-in components 50.

[0034] In this embodiment, by adding multiple connectors 50, which are circumferentially spaced on the outside of the tray frame 10 and connected to the tray frame 10 respectively, and by spacedly arranging the connectors 50 with the peripheral mounting beams 40, the liquid cooling plate 30 and the support frame 20 respectively, and by providing at least one peripheral mounting beam 40 between two adjacent connectors 50, not only are additional connection and fixing points provided for the tray frame 10, enhancing the flexibility and reliability of the connection between the component and the external structure, but also by avoiding mutual interference between components through the spaced arrangement with other components and the orderly layout with the peripheral mounting beams 40, ensuring that each component works independently and efficiently, and further improving the overall structural rationality and assembly adaptability of the battery tray assembly.

[0035] The second embodiment of this utility model provides a vehicle based on the first embodiment, including a vehicle body and a battery tray assembly of the first embodiment.

[0036] By applying this embodiment and configuring the battery tray assembly of the first embodiment on the vehicle body, the synergistic effect of components such as the tray frame 10, support frame 20, liquid cooling plate 30, peripheral mounting beam 40, and connector 50 in the battery tray assembly can be achieved. For example, the tray frame 10 forms a stable foundation through multiple frame connecting rods (including the first frame connecting rod 104 to the sixth frame connecting rod 103), the support frame 20 enhances the support strength with cross connecting brackets 201 and support rods 202, the liquid cooling plate 30 ensures battery heat dissipation through cooling channels 301, the peripheral mounting beam 40 improves circumferential stability, and the connector 50 optimizes external connection adaptability. This effectively improves the installation stability, structural safety, and heat dissipation reliability of the vehicle battery system, thereby providing strong support for the overall performance of the vehicle (such as range and safety protection). At the same time, the reasonable structural design of the battery tray assembly can also better adapt to the layout requirements of the vehicle body, helping the vehicle to achieve better space utilization and operating efficiency.
