Description

Technical Field

[0001] The utility model relates to the technical field of vehicle battery trays, and in particular to a tray, a battery pack and a vehicle. Background Art

[0002] New energy vehicles have gradually separated from the oil-to-electric platform. Improving the driving range and increasing the space inside the car are the fundamental purposes of the pure electric platform. In order to ensure the safety of passengers and the electrical safety of the battery distribution management system (distribution component), the battery distribution management system is generally installed inside the battery pack to meet the requirements of waterproofing, heat insulation, electromagnetic isolation, etc. As the integration of the battery distribution management system continues to increase, the number of components increases, the electrical gap between components decreases, and the possibility of electrical insulation failure and arcing increases. In the existing arrangement of battery cells, since the distribution area is not isolated from the battery cell area, when the battery cell produces smoke, the smoke will enter the battery distribution area, posing a major safety hazard. At the same time, during the charge and discharge cycle of the battery cell, in order to prevent the spread of thermal runaway, the battery cell explosion-proof valve will discharge the smoke generated in the battery cell, thereby affecting the battery distribution of the high-voltage part.

[0003] In the prior art, most trays do not have a barrier device for the distribution components and the battery cells, which means that when any area of ​​the battery cells or distribution components fails and smokes, it will affect the operation of another area. In addition, the battery pack tray is made of non-metallic materials and cannot isolate high-temperature smoke. Alternatively, in order to electrically connect the distribution components and the battery cells, a battery pack with a barrier device will have a gap in the barrier device (such as a beam) for passing electrical connectors (such as wires, copper bars, etc.). This will still cause the adjacent area to be affected when any area of ​​the battery cells or distribution components fails. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there can be a central component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there can be a central component at the same time.

[0033] Unless otherwise defined, all technical and scientific terms used in this utility model have the same meaning as those commonly understood by technicians in the technical field of this utility model. The terms used in the specification of this utility model are only for the purpose of describing specific embodiments and are not intended to limit this utility model. The term "and / or" used in this utility model includes any and all combinations of one or more related listed items.

[0034] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0035] The utility model provides a battery pack, which includes a tray, a battery cell, a power distribution assembly and a connection assembly, wherein the battery cell, the power distribution assembly and the connection assembly are all arranged in the tray, and the battery cell and the power distribution assembly are electrically connected through the connection assembly.

[0036] In one embodiment, the connection assembly includes a first connection assembly and a second connection assembly, wherein the first connection assembly may be a positive connection assembly and the second connection assembly may be a negative connection assembly. Of course, the first connection assembly may also be a negative connection assembly and the second connection assembly may be a positive connection assembly.

[0037] In one implementation, please refer to Figures 1 to 3 The tray includes a tray body 12, an upper cover 11 and a sealing block 111; wherein the tray body 12 encloses a battery cell cavity and a power distribution cavity, the tray body 12 includes a partition beam 121, and the two opposite sides of the partition beam 121 are the battery cell cavity and the power distribution cavity respectively, and the partition beam 121 has a gap; the upper cover 11 is covered on the tray body 12; and the sealing block 111 is connected to the upper cover 11 and closes the gap.

[0038] Specifically, Figure 1 As shown, the tray includes a length direction X, a width direction Y and a thickness direction Z. All directions mentioned below are based on the directions of the tray. The tray body 12 and the upper cover 11 are connected in the thickness direction Z of the tray. After the tray body 12 and the upper cover 11 are connected, the internal space thereof is independent from the outside. The above-mentioned battery cells, power distribution components and connection components are all installed in the internal space of the tray.

[0039] Optional, such as Figure 1 As shown, the tray further includes a protective plate 13, which is connected to the side of the tray body 12 facing away from the upper cover 11. Figure 1 As shown, the exploded view of the tray includes from top to bottom: an upper cover 11 , a tray body 12 and a protective plate 13 .

[0040] Optional, such as Figure 2 As shown, the tray body 12 is the bottom plate of the tray, and includes a main body and a partition beam 121 arranged on the main body. The partition beam 121 divides the interior of the tray body 12 to form a battery cell cavity and a distribution cavity, and the battery cell cavity and the distribution cavity are arranged in sequence in the length direction X.

[0041] Optionally, the partition beam 121 may be an Al6061 extruded aluminum part, and the partition beam 121 is connected to the main body of the disk body 12 by welding.

[0042] Optionally, the tray body 12 further includes other cross beams, and the other cross beams are used to separate the battery cell cavities.

[0043] Optional, such as Figure 3 and Figure 4As shown, the upper cover 11 is the cover of the tray. The upper cover 11 can be formed by one-time stamping of DP590 steel plate. The upper cover 11 is provided with a maintenance window, which is used to install a maintenance sheet metal. The maintenance sheet metal and the upper cover 11 are detachably connected. Rivet nuts are installed around the maintenance window. By opening the maintenance sheet metal, the power distribution module can be taken out for maintenance without opening the upper cover 11 and avoiding damage to the sealant between the plates of the upper tray body 12.

[0044] The upper cover 11 of the utility model is a steel punched top plate, and the plate body 12 is an aluminum punched bottom plate, so that the entire battery pack has the characteristics of high strength, corrosion resistance, high temperature resistance, etc.

[0045] Furthermore, a notch may be formed at the end of the partition beam 121 in the width direction Y. In the prior art, the notch on the partition beam 121 is used to pass through the electrical connection assembly to connect the battery cell and the distribution assembly. However, the notch results in poor sealing between the battery cell cavity and the distribution cavity. Therefore, the utility model is provided with a sealing block 111 at the notch, and the sealing block 111 is connected to the partition beam 121, so that the sealing block 111 and the partition beam 121 jointly separate the battery cell cavity and the distribution cavity. By using the combination of the partition beam 121 and the sealing block 111 as a barrier, the high-temperature smoke released by the battery cell can be blocked, and there is no need to add an independent isolation assembly, thereby reducing the use space inside and outside the battery pack and improving the volume utilization of the battery pack.

[0046] Optionally, the sealing block 111 can be connected to the upper cover 11, and after the upper cover 11 and the tray body 12 are assembled, the sealing block 111 extends into the gap. Alternatively, the sealing block 111 is directly connected to the partition beam 121, and after the upper cover 11 and the tray body 12 are assembled, the shapes of the sealing block 111 and the sheet metal of the upper cover 11 match, so that the sealing block 111 abuts against the upper cover 11.

[0047] In the prior art, most trays do not have a barrier device for the distribution components and the battery cells, which means that when any area of ​​the battery cells or distribution components fails and smokes, it will affect the operation of another area. In addition, the battery pack tray is made of non-metallic materials and cannot isolate high-temperature smoke. Alternatively, in order to electrically connect the distribution components and the battery cells, a battery pack with a barrier device will have a gap in the barrier device (such as a beam) for passing electrical connectors (such as wires, copper bars, etc.). This will still cause the adjacent area to be affected when any area of ​​the battery cells or distribution components fails.

[0048] Therefore, based on the above problems, the utility model provides a tray that can completely separate the battery cell cavity and the distribution cavity, the tray includes an upper cover 11 and a tray body 12, wherein the tray body 12 includes a partition beam 121 for separating the battery cell cavity and the distribution cavity, the partition beam 121 can adopt the existing cross beam design, retaining a gap, and by arranging a sealing block 111 at the gap to seal the gap, the combination of the partition beam 121 and the sealing block 111 serves as a barrier device, the battery cell cavity and the distribution cavity are independent of each other, and when any electrical device in the two cavities fails, they can avoid mutual influence, and can also avoid the influence of temperature changes of the distribution components on the performance of the battery cells, which can reduce the heat entering the battery cell area.

[0049] In one implementation, please refer to Figure 5 The sealing block 111 is made of metal, and the sealing block 111 is welded on the upper cover 11. Specifically, the sealing block 111 can be made of steel, and is connected to the inner wall surface of the upper cover 11 by laser welding.

[0050] like Figure 5 or Figure 6 As shown, the partition beam 121 can be fixed to the disk body 12 by welding or gluing, and then the sealing block 111 connected to the upper cover 11 forms a complete trapezoidal sealing surface and supporting structure, which increases the structural strength compared to the incompletely closed beam structure in the prior art.

[0051] In one implementation, please refer to Figure 6 The sealing block 111 is made of non-metallic material, and the sealing block 111 is bonded or injection molded on the partition beam 121. Specifically, the sealing block 111 can be made of rubber material, and is connected to the notch of the partition beam 121 by bonding or injection molding.

[0052] Different from the above-mentioned embodiment, in this embodiment, the steel sealing block 111 having a sealing function is replaced with a rubber sealing block 111 which is bonded or injected. Figure 6 As shown, after the upper cover 11 is installed, the sealing surface formed with the disc body 12 presents an arc-shaped surface at the sealing block 111.

[0053] In one implementation, please refer to Figure 2 and Figure 7 The sealing block 111 includes a first sealing block and a second sealing block. The partition beam 121 has a first notch and a second notch at both ends in the width direction Y. The first sealing block closes the first notch and is clamped with the partition beam 121. The second sealing block closes the second notch and is clamped with the partition beam 121.

[0054] Specifically, the number of the gaps may be two, namely the first gap and the second gap, which are located at opposite ends of the partition beam 121. Therefore, the number of the sealing blocks 111 may also be two, namely the first sealing block and the second sealing block.

[0055] Optionally, the sealing block 111 may be clamped with the partition beam 121 , that is, the sealing block 111 and the partition beam 121 are clamped with each other to be connected and fixed.

[0056] In one implementation, please refer to Figure 2 and Figure 7 The partition beam 121 includes a top edge and a bottom edge facing each other, the bottom edge is connected to the disk body 12, the length of the top edge is smaller than the length of the bottom edge, and in the width direction Y, the two ends of the bottom edge protrude from the two ends of the top edge respectively.

[0057] Specifically, the shape of the partition beam 121 can be a trapezoid, that is, the top side is short and the bottom side is long, and the oblique sides opposite to each other in the width direction Y form an acute angle with the bottom side. Therefore, the first notch and the second notch mentioned above are formed by the oblique sides at both ends of the trapezoid. Among them, the top side is the side where the partition beam 121 connects to the upper cover 11, and the bottom side is the side where the partition beam 121 connects to the disk body 12.

[0058] In one implementation, please refer to Figure 7 A first groove 1211 is provided on the top edge, the opening of the first groove 1211 faces away from the bottom edge, and the first groove 1211 is used to receive the sealant.

[0059] Specifically, the first groove 1211 extends along the width direction Y, and the opening of the first groove 1211 faces the upper cover 11 . The first groove 1211 is used for injecting sealant to improve the sealing performance.

[0060] By opening a first groove 1211 at the top edge of the partition beam 121 between the upper cover 11 and the disk body 12, and pouring sealant or pasting a sealing strip (not limited to these two sealing methods) in the first groove 1211, when the upper cover 11 and the disk body 12 are closed, the partition beam 121 is sealed with the upper cover 11 through the strip, thereby increasing the airtightness between the distribution cavity and the battery cell cavity.

[0061] In one implementation, please refer to Figure 7 The disc body 12 further includes a fitting member 126, which is disposed at the notch and connected to the partition beam. The fitting member 126 defines a second groove 1261, which is communicated with the first groove 1211, and is used to receive the sealant.

[0062] Specifically, the fitting member 126 includes a first fitting member and a second fitting member, wherein the first fitting member is disposed at the first notch and connects the hypotenuse of the partition beam 121 , and the second fitting member is disposed at the second notch and connects the other hypotenuse of the partition beam 121 .

[0063] Optionally, the partition beam 121 is clamped with the sealing block 111 through a fitting 126 . Furthermore, the fitting 126 is welded to the partition beam 121 .

[0064] Furthermore, a second groove 1261 is formed on a side of the fitting 126 facing the upper cover 11, and the second groove 1261 is connected to the first groove 1211. Therefore, the second groove 1261 is also used to contain the sealant.

[0065] It needs to be explained that before the upper cover 11 and the disk body 12 are installed, a sealant can be applied to the first groove 1211 and the second groove 1261, or a sealing strip can be pasted to improve the sealing of the two cavities after the upper cover 11 and the disk body 12 are installed.

[0066] In one implementation, please refer to Figure 8 An electrode slot 1251 is provided on the partition beam 121. The electrode slot 1251 is provided on a side of the partition beam 121 facing the power distribution cavity. The electrode slot 1251 is used to install the first connection component.

[0067] Specifically, the electrode slot 1251 is connected to the first groove 1211. The electrode slot 1251 is located on a side of the partition beam 121 facing the power distribution cavity, and the electrode slot 1251 extends downward from the top edge of the partition beam 121.

[0068] In one implementation, please refer to Figure 8 An electrode socket 1252 is provided on the partition beam 121 , and the electrode socket 1252 passes through the partition beam 121 . The electrode socket 1252 is used for installing the second connection component.

[0069] Specifically, the partition beam 121 is provided with an electrode insertion hole 1252 , and the electrode insertion hole 1252 passes through two opposite sides of the partition beam 121 in the length direction X.

[0070] In one implementation, please refer to Figure 8 The first connection assembly includes a positive copper bar 123 and a sealing plug-in 122 . The positive copper bar 123 is connected to the sealing plug-in 122 , and the sealing plug-in 122 is snapped into the electrode slot 1251 .

[0071] Specifically, the positive copper bar 123 is used to electrically connect to the positive electrode of the battery cell. The positive copper bar 123 extends along the length direction X. One end of the positive copper bar 123 is connected to the tail of the disk body 12 (i.e., the end of the disk body 12 away from the partition beam 121), and the other end extends to the partition beam 121.

[0072] Optionally, one end of the positive copper busbar 123 is led out from the positive electrode of the battery cell, and then the positive copper busbar 123 extends above the battery cell so that the other end passes through the partition beam 121 and is connected to the relay of the power distribution assembly.

[0073] Furthermore, the sealing plug-in 122 is connected to the end of the positive copper bar 123 away from the rear of the disk body 12, and the sealing plug-in 122 is snapped into the electrode slot 1251. In addition, the positive copper bar 123 also extends from the sealing plug-in 122 to be connected to the power distribution assembly.

[0074] Optionally, the sealing plug-in 122 may be a snap-fit ​​structure, so as to be snap-fitted into the electrode slot 1251. Furthermore, the sealing plug-in 122 is installed into the electrode slot 1251 from top to bottom (from the top edge to the bottom edge). The sealing plug-in 122 may be a plastic part made of plastic material.

[0075] Optionally, a sealing ring 1221 is further provided on the surface of the positive copper busbar 123 , and the sealing ring 1221 can be manufactured by injection molding.

[0076] It needs to be explained that before the upper cover 11 and the disk body 12 are installed, the positive copper busbar 123 is first installed in the electrode slot 1251, and then sealant is applied to the electrode slot 1251 and the first groove 1211. Finally, the sealing plug-in 122 is installed from top to bottom into the electrode slot 1251. The sealing plug-in 122 is clamped in the sealing ring 1221, so that the positive copper busbar 123 forms a seal with the side wall of the partition beam 121.

[0077] In one implementation, please refer to Figure 8 The second connecting component includes a connector 127, a sealing cover 128 and a negative copper busbar 124. An electrode socket 1252 is provided on the partition beam 121. The connector 127 is arranged on a side of the partition beam 121 facing the distribution cavity. The sealing cover 128 is arranged on a side of the partition beam 121 facing the battery cell cavity. The connector 127 is passed through the electrode socket 1252 and connected to the sealing cover 128. The negative copper busbar 124 is passed through the connector 127 and the sealing cover 128.

[0078] Specifically, the connector 127 is arranged on the side of the partition beam 121 facing the distribution cavity, and the sealing cover 128 is arranged on the side of the partition beam 121 facing the battery cell cavity. The connector 127 at least partially extends into the electrode socket 1252, and the sealing cover 128 also at least partially extends into the electrode socket 1252, so that the connector 127 and the sealing cover 128 are matched and connected in the electrode socket 1252.

[0079] Optionally, the connector 127 and the sealing cover 128 are fixed to the partition beam 121 by the same set of fixing bolts. Preferably, the connector 127 and the sealing cover 128 are locked to the partition beam 121 by two bolts, so that the second connection assembly forms a seal with the side wall of the partition beam 121.

[0080] Optionally, the negative copper busbar 124 is passed through the connector 127, and after the connector 127 and the sealing cover 128 are connected, the negative copper busbar 124 also passes through the sealing cover 128, so that at least a portion of the negative copper busbar 124 is exposed in the battery cell cavity and connected to the battery cell in the battery cell cavity; the negative copper busbar 124 is also at least partially exposed in the distribution cavity and connected to the distribution assembly in the battery cell cavity.

[0081] like Figure 8 As shown, the negative copper bar 124 can be embedded in the connector 127, and then combined with the connector 127 to form a component, and thus installed together on the partition beam 121. The negative copper bar 124 is connected to the negative electrode of the battery cell by laser welding near the battery cell side, and is connected to the copper bar on the power distribution side by bolts near the power distribution side.

[0082] Optionally, the connector 127 and the sealing cover 128 are both made of ceramic material, so that the negative copper bus 124 is wrapped with the connector 127 and the sealing cover 128 made of ceramic material and installed on the partition beam 121, which can play the role of insulation and sealing the flue gas.

[0083] The second connecting assembly provided by the utility model directly installs the negative copper busbar 124 and the connector 127 in combination on the partition beam 121, which can fix the copper busbar and the partition beam 121 while ensuring the insulation; compared with the prior art, the structure provided by the utility model is more solid and reliable, and has good sealing performance; at the same time, the negative copper busbar 124 passes through the partition beam 121 and is fixed, which can reduce a copper busbar bracket in the distribution cavity, saving the distribution cavity space.
