For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] Reference below Figure 1-Figure 6 A battery tray 100 according to an embodiment of the present invention is described.

[0042] like Figure 1 As shown, a battery tray 100 according to an embodiment of the utility model includes a frame 1, a beam 2 and a jumper assembly 3.

[0043] Specifically, the battery tray 100 is used for a battery pack, and the battery pack includes an upper cover. The crossbeam 2 is arranged in the frame 1, and the two sides of the crossbeam 2 have installation spaces for installing the battery module 200. A plurality of battery modules 200 may be arranged in the battery pack, and the plurality of battery modules 200 are separated by the crossbeam 2. When thermal runaway occurs in one of the battery modules 200, the crossbeam 2 can prevent the spread of the thermal runaway, and try to control the thermal runaway within the space where the battery module 200 with thermal runaway exists, thereby increasing the thermal safety of the battery pack.

[0044] like Figure 1 As shown, a groove 21 is provided on the cross beam 2, and the jumper assembly 3 is arranged in the groove 21 for connecting the battery modules 200 on both sides of the cross beam 2. This can prevent the jumper assembly 3 from being higher than the upper surface of the cross beam 2 and can fully utilize the space inside the battery pack.

[0045] In the prior art, the height of the jumper assembly is lower than the upper surface of the beam, and there is a certain gap between the top of the jumper assembly and the upper cover. After a single battery module thermally runs away, smoke can jump to other battery modules through the cavity above the jumper assembly, easily causing thermal runaway of other battery modules.

[0046] like Figure 1 and Figure 2 As shown, a glue channel 321 is provided on the upper surface of the jumper assembly 3, and the glue channel 321 is suitable for being filled with fixing glue for connection with the upper cover, so that a relatively complete wall is formed between the jumper assembly 3 and the upper cover to isolate the smoke, thereby preventing the smoke from spreading from the top of the jumper assembly 3 to other battery modules 200 on the other side of the beam 2 when a single battery module 200 has thermal runaway, thereby achieving heat diffusion blocking between multiple battery modules 200, which significantly improves the thermal safety of the battery pack.

[0047] According to the battery tray 100 of the embodiment of the utility model, by setting a groove 21 on the crossbeam 2, the jumper assembly 3 is set in the groove 21, and the battery modules 200 installed on both sides of the crossbeam 2 can be connected, which can prevent the jumper assembly 3 from being higher than the upper surface of the crossbeam 2, and can make full use of the space inside the battery pack. In addition, a glue channel 321 is provided on the upper surface of the jumper assembly 3, and the glue channel 321 is suitable for filling with fixing glue for connection with the upper cover, so that a relatively complete wall is formed between the jumper assembly 3 and the upper cover to isolate the smoke, and prevent the smoke from spreading from the top of the jumper assembly 3 to other battery modules 200 on the other side of the crossbeam 2 when a single battery module 200 is thermally runaway, thereby achieving thermal diffusion blocking between multiple battery modules 200, which has a significant improvement in the thermal safety of the battery pack.

[0048] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the jumper assembly 3 includes a jumper connecting piece 31 and an upper insulating bracket 32. The jumper connecting piece 31 is arranged on the groove 21. The length direction of the jumper connecting piece 31 (such as Figure 2 The two ends of the crossbar 2 (in the direction a shown in the figure) are used to connect with the battery modules 200 on both sides of the crossbar 2, so as to realize the electrical connection of the battery modules 200 on both sides of the crossbar 2. The jumper connecting piece 31 is a metal piece, such as a copper nickel-plated connecting piece, a pure nickel connecting piece, a nickel-plated steel connecting piece, etc., which can be selected according to demand and cost.

[0049] The upper insulating bracket 32 ​​is located above the jumper connecting piece 31. The upper insulating bracket 32 ​​has an insulating effect, which can prevent the jumper connecting piece 31 from being connected. The adhesive channel 321 is arranged on the upper surface of the upper insulating bracket 32, so that a relatively complete wall is formed between the upper insulating bracket 32 ​​and the upper cover to isolate the smoke, thereby preventing the smoke from spreading from the top of the jumper assembly 3 to other battery modules 200 on the other side of the beam 2 when a single battery module 200 has thermal runaway, thereby achieving heat diffusion blocking between multiple battery modules 200, which significantly improves the thermal safety of the battery pack.

[0050] In some embodiments of the present invention, the upper insulating bracket 32 ​​is a ceramic bracket. The ceramic bracket has the advantages of insulation and high temperature resistance, which can prevent the upper insulating bracket 32 ​​from melting after the battery thermal runaway, avoid the jumper connecting piece 31 and the upper cover from being connected, and increase the electrical safety of the jumper assembly 3.

[0051] In some embodiments of the present invention, Figure 2 , Figure 4 and Figure 5 As shown, the jumper assembly 3 also includes a lower insulating bracket 33, which is mounted in the groove 21, and the jumper connecting piece 31 is mounted above the lower insulating bracket 33. The lower insulating bracket 33 is spaced between the jumper connecting piece 31 and the cross beam 2, which can prevent the jumper connecting piece 31 from being connected to the cross beam 2, thereby increasing the electrical safety of the battery pack. The lower insulating bracket 33 is snap-connected with the upper insulating bracket 32, and a first buckle 333 is provided on the lower insulating bracket 33. The lower surface of the first buckle 333 abuts against the upper surface of the upper insulating bracket 32, so that the connection between the upper insulating bracket 32 ​​and the lower insulating bracket 33 is relatively simple, and the position of the lower insulating bracket 33 is relatively reliable.

[0052] Furthermore, if Figure 2 , Figure 4 and Figure 5 As shown, the lower insulating bracket 33 includes a first bracket 331 and a second bracket 332. The first bracket 331 is disposed in the groove 21, and the second bracket 332 is disposed above the first bracket 331 and connected to the first bracket 331. Two layers of the first bracket 331 and the second bracket 332 are disposed between the bridging connecting piece 31 and the cross beam 2. When one of the first bracket 331 and the second bracket 332 is damaged, the other can still achieve the insulation effect of the bridging connecting piece 31 and the cross beam 2, so that the insulation between the bridging connecting piece 31 and the cross beam 2 is more reliable.

[0053] In some embodiments of the present invention, the first bracket 331 and the second bracket 332 are connected by snapping, and the connection between the first bracket 331 and the second bracket 332 is relatively simple.

[0054] In some embodiments of the utility model, the first bracket 331 is a plastic bracket, and the second bracket 332 is a ceramic bracket. Both the first bracket 331 and the second bracket 332 have good insulation, and the ceramic bracket has good high temperature resistance, which can prevent the plastic bracket from melting after the battery module 200 in the battery pack is thermally runaway, causing the jumper connecting piece 31 and the crossbeam 2 to be connected. After the plastic bracket melts, the ceramic bracket is still set between the jumper connecting piece 31 and the crossbeam 2, ensuring the insulation effect of the jumper connecting piece 31 and the crossbeam 2.

[0055] In some embodiments of the present invention, Figure 2 As shown, the jumper assembly 3 also includes a sampling assembly 34 , one end of which is connected to the jumper connecting piece 31 . The sampling assembly 34 can collect signals on the jumper connecting piece 31 to monitor the electrical connection between the battery modules 200 .

[0056] Furthermore, the sampling assembly 34 includes a sampling piece 341, a sampling harness 342 and a connector 343. The sampling piece 341 is fixedly connected to the jumper connecting piece 31, and the connection between the sampling piece 341 and the jumper connecting piece 31 is relatively simple. One end of the sampling harness 342 is connected to the sampling piece 341, and the connector 343 is connected to the other end of the sampling harness 342. The connector 343 can improve the production process, simplify the assembly process of the sampling assembly 34, and also simplify the mass production process; and the sampling assembly 34 is easy to maintain, and can be quickly replaced when the sampling assembly 34 fails.

[0057] Furthermore, the sampling piece 341 and the jumper connecting piece 31 are first connected by riveting and then by welding. The sampling piece 341 and the jumper connecting piece 31 are connected twice, and the connection between the sampling piece 341 and the jumper connecting piece 31 is relatively firm, so as to prevent the sampling piece 341 from being separated from the jumper connecting piece 31 after being dragged by the sampling harness 342 when the battery pack is flipped and moved, thereby ensuring the reliability of the sampling component 34 collecting the signal on the jumper connecting piece 31, and realizing the monitoring of the electrical connection between the battery modules 200.

[0058] In some embodiments of the present invention, multiple battery modules 200 are provided on both sides of the beam 2, and the multiple battery modules 200 located on the same side of the beam 2 are arranged along the length direction of the beam 2 (such as Figure 2 The battery modules 200 on one side of the beam 2 are arranged in a one-to-one correspondence with the battery modules 200 on the other side. The jumper components 3 are multiple corresponding to the battery modules 200 on one side of the beam 2, and the jumper components 3 are arranged at intervals along the length direction of the beam 2. Each jumper component 3 can realize the electrical connection of the two corresponding battery modules 200 on both sides of the beam 2, so that the electrical connection between the battery modules 200 on one side of the beam 2 and the battery modules 200 on the other side in the battery pack is relatively reliable.

[0059] Furthermore, if Figure 6 As shown, a longitudinal beam 4 is provided in the installation space, and along the length direction of the cross beam 2, a longitudinal beam 4 is provided between any two adjacent battery modules 200 in the same installation space, which can increase the overall strength of the battery pack and make the structure of the battery pack more reliable. In addition, a plurality of battery modules 200 are separated by the longitudinal beam 4. When thermal runaway occurs in one of the battery modules 200, the cross beam 2 and the longitudinal beam 4 can both block the spread of the thermal runaway and try to control the thermal runaway within the space where the battery module 200 with thermal runaway exists, thereby increasing the thermal safety of the battery pack.

[0060] The battery pack according to the embodiment of the utility model includes the above-mentioned battery tray 100, the upper cover and the battery module 200. The upper cover is arranged on one side of the frame 1 and connected to the frame 1. The jumper assembly 3 and the upper cover are connected by fixing glue, and a battery module 200 is arranged in each installation space. A relatively complete wall is formed between the jumper assembly 3 and the upper cover to isolate the smoke, so as to prevent the smoke from spreading from the top of the jumper assembly 3 to other battery modules 200 on the other side of the beam 2 when a single battery module 200 is thermally runaway, thereby realizing the thermal diffusion blocking between multiple battery modules 200, which has a significant improvement on the thermal safety of the battery pack.
