Detailed implementation manners

[0035] The following will describe in detail the specific implementation manners of the present disclosure with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for explaining and illustrating the present disclosure, and are not used to limit the present disclosure.

[0036] In the present disclosure, unless otherwise stated, the orientation terms such as "upper, lower" are defined according to the installation habit of the battery pack, and can be specifically understood in combination with the accompanying drawings. "Inner, outer" refer to the inside and outside of the contour of the corresponding component itself. The terms "first, second" used in the present disclosure are used to distinguish one element from another, and do not have sequence and importance.

[0037] Referring to Figure 4 and Figure 5 , an embodiment of the present disclosure provides a partition beam assembly 300 of a battery pack for dividing the battery pack into multiple regions. Referring to Figure 1 and Figure 2 , the partition beam assembly 300 includes a first beam 1. A first accommodation cavity 111 is formed inside the first beam 1, and the accommodation cavity 111 can extend in the same direction as the first beam 1. A first insulating part 121 is arranged in the first accommodation cavity 111. The first insulating part 121 divides the first accommodation cavity 111 into a first sub - cavity 1111 and a second sub - cavity 1112. One of the first sub - cavity 1111 and the second sub - cavity 1112 is used to accommodate the high - voltage conductive part 101 connected to the battery pack 100, and the other is used to accommodate the low - voltage conductive part 102 connected to the battery pack 100. For example, the first sub - cavity 1111 is used to accommodate the low - voltage conductive part 102, and the second sub - cavity 1112 is used to accommodate the high - voltage conductive part 101. Among them, the high - voltage conductive part 101 can be a high - voltage wire harness or a high - voltage busbar (such as a high - voltage copper busbar), and the low - voltage conductive part 102 can be a low - voltage wire harness. Since the first sub - cavity 1111 and the second sub - cavity 1112 here are used to arrange the high - voltage and low - voltage circuits of the battery pack, the extension directions of the two sub - cavities conform to the arrangement directions of the high - voltage and low - voltage circuits, that is, they are determined according to the distribution of the battery pack 100.

[0038] Through the above technical solution, the high-voltage conductive member 101 and the low-voltage conductive member 102 of the battery pack are arranged in the first accommodating cavity 111 of the first beam 1, so that while the strength of the battery pack is improved through the first beam 1, it can also play an accommodating role. This structure is compact, improving the space utilization rate of the battery pack, thereby increasing the energy density of the battery pack. Moreover, the high-voltage conductive member 101 and the low-voltage conductive member 102 can be separated by the first insulating member 121 and accommodated in the corresponding sub-cavities to play a role in limiting and fixing the two, preventing entanglement and shaking friction to protect the conductive members. In addition, the insulating member 121 can enhance the insulation effect and avoid the risk of arc short circuit.

[0039] Among them, the first beam 1 may include a structural beam 13 for forming one side wall of the first accommodating cavity 111, and the other side walls of the first accommodating cavity 111 may be formed by the side walls of the first beam 1. The structural beam 13 may include a protrusion 131 and at least one recess 132. The first insulating member 121 may be lapped on the protrusion 131 to be limited and fixed by the protrusion 131. The area between the first insulating member 121 and the recess 132 may form a first sub-cavity 1111. In the embodiment of the present disclosure, by providing the structural beam 13 with protrusions and recesses, it can provide installation for the first insulating member 121 and also provide a suitable installation space for the conductive members. For example, the low-voltage conductive member 102, such as a low-voltage wire harness, may be accommodated in the first sub-cavity 1111, and the protrusion height of the protrusion 131 (i.e., the recess height of the recess 132) and other dimensions of the recess 132 may be designed according to the size of the low-voltage wire harness. Among them, the number of the protrusion 131 and the recess 132 may be adaptively adjusted according to the number of conductive members to be accommodated. In the embodiment of the present disclosure, even if the number of conductive members to be accommodated is one, one protrusion 131 and two recesses 132 may be provided so that the protrusion 131 supports the first insulating member 121 in the middle to ensure the fixing effect. And setting two recesses 132 can also reserve an accommodating space, so that the product has a wider range of applications. In the embodiment of the present disclosure, the first insulating member 121 may also be installed on the first beam 1 by a buckle to further improve the fixing effect on the conductive members.

[0040] In the embodiment of the present disclosure, a second insulating member 122 may be provided in the first accommodating cavity 111. The area between the second insulating member 122 and the first insulating member 121 may form a second sub-cavity 1112. In this way, the conductive members can be arranged and fixed in the sub-cavities surrounded by the two insulating members. Among them, the second sub-cavity 1112 may be used to accommodate a high-voltage busbar, and the second insulating member 122 further plays an insulating effect. The second insulating member 122 may be installed on the first beam 1. Specifically, the second insulating member 122 may be located above the first insulating member 121, so that the upper components can all be supported by the protrusion 131.

[0041] The first beam 1 can be a hollow beam with an open side, and thus the first accommodating cavity 111 can be constructed as an open cavity. The opening of the first accommodating cavity 111 can be covered by a second insulating member 122 to prevent the components in the first accommodating cavity 111 from contacting and wearing against other structures outside the first beam 1, and to protect the components in the first accommodating cavity 111.

[0042] Both the first insulating member 121 and the second insulating member 122 can be made of plastic material, which has low cost, good insulation property, and still ensures good rigidity in the case of large size to ensure the supporting or limiting effect on the conductive member.

[0043] The first insulating member 121 or the second insulating member 122 can be formed with a ribbed structure, or both can be formed with a ribbed structure. By setting the ribbed structure, the self-strength of the insulating member is enhanced, and the fixing and limiting effect on the conductive member is improved.

[0044] In the embodiment of the present disclosure, a second accommodating cavity 112 can be formed inside the first beam 1, and the second accommodating cavity 112 is used to arrange a reinforcing member to ensure the structural strength enhancement effect of the first beam 1 on the battery pack.

[0045] The reinforcing member can be constructed as a reinforcing beam 14, and the reinforcing beam 14 extends in the same direction as the first beam 1. To ensure the insulation effect on the conductive member, the first beam 1 can be made of an insulating material, such as a glass fiber composite material, which has high strength, good insulation property, and high temperature resistance. Based on this, the structural strength of the first beam 1 made of insulating material can be improved by arranging the reinforcing beam 14 extending in the same direction as the first beam 1 in the second accommodating cavity 112.

[0046] Furthermore, the cross-section of the reinforcing beam 14 can be constructed as a "day" shape, so that the reinforcing beam 14 has high structural strength, thereby improving the structural strength of the battery pack.

[0047] Among them, the reinforcing beam 14 can be constructed as a metal beam, for example, a beam made of aluminum material, to achieve a high-strength and lightweight structure. Both ends of the metal beam can be connected to the first beam 1 through insulating blocks 141. Since the first beam 1 is made of insulating material, the insulating blocks 141 are connected between the first beam 1 and the reinforcing beam 14 to isolate the reinforcing beam 14 and the conductive member in the first accommodating cavity 111 through the insulating blocks 141, so that the conductive member is in an insulating environment and the risk of arc short circuit is avoided.

[0048] In the embodiments of the present disclosure, the first accommodation cavity 111 and the second accommodation cavity 112 are vertically separated along the thickness direction of the battery pack, and the second accommodation cavity 112 can be located below the first accommodation cavity 111. Since the weight of the reinforcing beam 14 accommodated in the second accommodation cavity 112 is heavier than the weights of the components accommodated in the first accommodation cavity 111, the heavier part is arranged below to ensure stability and avoid the situation of "top-heavy and bottom-light". Moreover, the reinforcing beam 14 is closer to the bottom of the tray of the battery pack, which can ensure the structural strengthening effect on the battery pack.

[0049] According to an embodiment of the present disclosure, with reference to Figure 3 and Figure 4 , the partition beam assembly may further include a second beam 2. The second beam 2 is used to divide the accommodation cavity of the battery tray into two parts separated along the first direction. The first beam 1 extends along the first direction, and a set of the first beams 1 is arranged on each side of the second beam 2 along the first direction. For example, the second beam 2 can be a cross beam, and the first beam 1 can be a longitudinal beam. A set of longitudinal beams can be arranged on each side of the cross beam, so that the interior of the battery pack is divided into four regions. The conductive parts in the longitudinal beams on both sides can be configured as the same conductive part, that is, a high-voltage conductive part 101 extends into the two longitudinal beams at the same time, and a low-voltage conductive part 102 extends into the two longitudinal beams at the same time. The high-voltage conductive part 101 and the low-voltage conductive part 102 will cross the cross beam.

[0050] Specifically, a accommodation notch 21 can be formed on the second beam 2 for the high-voltage conductive part 101 and the low-voltage conductive part 102 in the first beams 1 on both sides to pass through. In this way, the conductive parts can be accommodated in the accommodation notch 21 without additionally occupying other spaces of the battery pack. The size of the accommodation notch 21 can be adapted to the components to be accommodated to avoid being too large and affecting the strength of the second beam 2.

[0051] When the second beam 2 needs to ensure strength, it can be made of a metal material. Therefore, an insulating bracket 22 can be accommodated and installed in the accommodation notch 21 for arranging the high-voltage conductive part 101 and the low-voltage conductive part 102 to play an insulating and protective role.

[0052] The accommodation notch 21 can also accommodate a first insulating partition 231, a second insulating partition 232, and a third insulating partition 233. The first insulating partition 231, the second insulating partition 232, and the third insulating partition 233 can be directly or indirectly installed on the insulating bracket 22. For example, the first insulating partition 231 can be installed on the insulating bracket 22, and the second insulating partition 232 and the third insulating partition 233 can be connected to the insulating bracket 22 through the first insulating partition 231. Wherein, intervals are formed between the first insulating partition 231 and the second insulating partition 232, and between the second insulating partition 232 and the third insulating partition 233, respectively for the high-voltage conductive member 101 and the low-voltage conductive member 102 to pass through. For example, the high-voltage conductive member 101 can be accommodated in the interval between the second insulating partition 232 and the third insulating partition 233, and the low-voltage conductive member 102 can be accommodated in the interval between the first insulating partition 231 and the second insulating partition 232, so that the two conductive members straddling the second beam 2 can also be insulated and separated and limited in position.

[0053] Wherein, the structure of each insulating partition can be adaptively adjusted according to the number, shape, and size of the conductive members to be accommodated. The uppermost third insulating partition 233 can include a shielding portion extending towards the first beam 1 to shield the conductive members extending from the first beam 1 above, thereby providing insulating protection for the conductive members.

[0054] In the embodiments of the present disclosure, the first insulating partition 231, the second insulating partition 232, and the third insulating partition 233 can all be made of ceramic materials. Ceramic materials have the characteristic of high temperature resistance. Since the second beam 2 divides the battery pack into two parts, in order to avoid the gas leakage between the two parts of the battery pack 100 separated by the second beam 2, a high-temperature resistant material is provided to ensure the effect of the second beam 2 intercepting the hot-diffused high-temperature gas.

[0055] The outer contour of the insulating bracket 22 can match the shape of the accommodation notch 21, so that the insulating bracket 22 is just arranged in the accommodation notch 21, for example, it can be inserted into the accommodation notch 21. Structural adhesive can be filled in the voids of the insulating bracket 22. The voids here refer to the remaining space inside the insulating bracket 22 after installing the insulating partitions and the high-voltage conductive member 101 and the low-voltage conductive member 102. By filling the remaining space with structural adhesive, the accommodation notch 21 can be sealed and the insulating bracket 22 can be fixed. Thus, the position where the first beam 1 and the second beam 2 intersect has good insulation and sealing effects, effectively avoiding the flow of high-temperature gas when the battery packs 100 on both sides of the second beam 2 are thermally out of control, thereby reducing the risk of thermal diffusion and improving the overall safety of the battery pack.

[0056] According to the second aspect of the embodiments of the present disclosure, refer to Figure 4, a battery tray is provided, which includes a tray body 200 and a partition beam assembly 300. The tray body 200 forms a receiving cavity, and the partition beam assembly 300 is disposed in the receiving cavity. The partition beam assembly 300 is the partition beam assembly of the above-mentioned battery pack. This battery tray has all the beneficial effects of the above-mentioned partition beam assembly, which will not be elaborated here.

[0057] Among them, the bottom of the partition beam assembly 300 can be bonded to the tray body 200. For example, when having the above-mentioned first beam 1 and second beam 2, the bottom of the first beam 1 or the second beam 2 is bonded to the tray body 200, or both are bonded to the tray body 200. The bonding has good sealing performance and can avoid the thermal diffusion of the battery pack.

[0058] The tray body 200 includes side beams 201. When the partition beam assembly 300 includes the above-mentioned second beam 2, both ends of the second beam 2 in the extending direction can be welded to the side beams 201, making the connection reliable, with higher strength and stronger integrity.

[0059] According to the third aspect of the embodiments of the present disclosure, a battery pack is provided, which includes the above-mentioned battery tray and a plurality of battery groups 100 disposed on the battery tray. The plurality of battery groups 100 can be respectively disposed on both sides of the first beam 1. This battery pack has all the beneficial effects of the above-mentioned battery tray, which will not be elaborated here.

[0060] Furthermore, referring to Figure 4 , the battery pack can include an upper cover 400 covering the battery tray, and the top of the partition beam assembly 300 can be bonded to the upper cover 400. The upper cover 400 and the battery tray enclose a closed space for accommodating the battery groups 100. The bonding method can ensure the sealing effect and avoid the thermal diffusion of the battery groups 100.

[0061] In the embodiments of the present disclosure, the battery groups 100 can also be bonded between the upper cover 400 and the battery tray for fastening installation and ensuring the sealing effect. In addition, fasteners can penetrate the upper cover 400, the partition beam assembly, and the battery tray in the thickness direction of the battery pack to make the connection of the battery pack reliable and stable.

[0062] When the partition beam assembly 300 includes the second beam 2, the second beam 2 divides the battery pack into two parts separated along the first direction, and the battery groups 100 in each part can be spaced apart from the second beam 2, so that there is an electrical gap between the second beam 2 and the battery groups 100, reducing the high-voltage safety risk. Here, the explosion-proof valves of the battery groups 100 are set for the second beam 2, so the electrical gap is used to achieve the insulation effect and improve the safety of the battery pack during use. This electrical gap can be set to 10 mm to 20 mm.

[0063] When the second beam 2 is a metal beam, an insulating film can be attached to its outer side to ensure the insulation effect and avoid the high-voltage safety risk.

[0064] According to the fourth aspect of the embodiments of the present disclosure, there is provided an electrical device, which includes the above-mentioned battery pack and has all the beneficial effects of the above-mentioned battery pack, which will not be elaborated here. Among them, the electrical device includes, but is not limited to, vehicles, aircraft, ships, computers, energy storage cabinets, etc.

[0065] The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0066] In addition, it should be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination methods.

[0067] Furthermore, any combination can be made between various different embodiments of the present disclosure as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
