Abstract
Description
Technical Field
[0001] The present application relates to the technical field of battery production, and in particular, to a battery module and a battery pack including the same. Background Art
[0002] A battery pack is the core energy source of a new energy electric vehicle and is formed by encapsulating multiple battery modules. A battery module includes a module upper cover, a busbar, a housing, and battery cells. Among them, multiple battery cells are encapsulated in the space surrounded by the module upper cover and the housing and are connected in series through the busbar. The busbar is connected to the module upper cover through a busbar bracket. The module upper cover plays a role in protecting the internal structure of the battery module and preventing foreign objects from entering the inside of the battery module and causing insulation failure.
[0003] The module upper cover is generally made of plastic material, but the plastic module upper cover cannot play a role in preventing thermal runaway. With the increasing requirements for the thermal runaway prevention performance of the battery pack, some battery manufacturers will replace the entire plastic module upper cover with mica material, which has advantages such as high temperature resistance, high voltage insulation strength, and low gas permeability. Existing busbar brackets are usually injection-molded parts or vacuum-formed parts. Compared with injection-molded busbar brackets, vacuum-formed busbar brackets have the advantages of light weight and high strength, and gradually replace traditional injection-molded busbar brackets and are applied to battery modules. However, the texture of the vacuum-formed busbar bracket is relatively soft and the thickness is relatively thin. After it is assembled with the mica module upper cover, it is prone to tearing or cracking of the busbar bracket and the module upper cover during vibration tests, and the reliability of their assembly cannot be guaranteed.
[0004] In view of this, the present application is specifically proposed. Utility Model Content

Detailed Embodiments
[0032] The technical solution of the present application will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.
[0033] In an embodiment of the present application, a battery module 100 is provided. For the specific structure of the battery module 100, please refer to Figures 1 to 6 , which includes a module upper cover 110 and a busbar assembly 120. Among them, the busbar assembly 120 includes a busbar 121 and a busbar bracket 122 for fixing the busbar 121. The busbar bracket 122 is provided with a clamping member 123 protruding upward. The clamping member 123 forms a clamping space for clamping the module upper cover 110. The battery module 100 is configured such that the module upper cover 110 can move in a first direction to be limited in the clamping space, and the first direction is parallel to the plane where the module upper cover 110 is located.
[0034] According to the battery module 100 of the present application, by clamping the module upper cover 110 with the clamping member 123, not only can the quick assembly of the module upper cover 110 and the busbar bracket 122 be ensured, improving the assembly efficiency of the battery module 100, but also the module upper cover 110 can be limited and fixed to prevent the module upper cover 110 from moving relative to the busbar bracket 122, enhancing the reliability of the assembly of the module upper cover 110 and the busbar bracket 122.
[0035] As Figure 1 , Figure 3 and Figure 5 shown, the first direction is substantially perpendicular to the height direction of the battery module 100, that is, the first direction is substantially perpendicular to the z-axis direction. The first direction can be substantially parallel to the length direction of the battery module 100, that is, the first direction can be the x-axis direction. Of course, the first direction can also be substantially parallel to the width direction of the battery module 100, that is, the first direction can also be the y-axis direction. For the convenience of description, in this embodiment, the first direction is substantially parallel to the length direction of the battery module 100, that is, the first direction is the x-axis direction. The module upper cover 110 can move in the x-axis direction to be limited in the clamping space, realizing the limitation and fixation of the module upper cover 110 in the x-axis direction, so that the battery module 100 can withstand the vibration and shock in the x-axis direction.
[0036] As Figure 1 and Figure 5As shown, the busbar bracket 122 is formed by a thermoforming process. At least two clamping members 123 are arranged at one end of the busbar bracket 122 along the first direction at intervals in a second direction perpendicular to the first direction, and are used to clamp different positions of the module upper cover 110. The structure is simple and the limiting effect is good, which can make the assembly of the module upper cover 110 and the busbar bracket 122 more reliable.
[0037] As Figure 1 , Figure 3 and Figure 5 shown, the second direction is substantially perpendicular to the height direction of the battery module 100, that is, the second direction is substantially perpendicular to the z-axis direction. In this embodiment, the first direction is substantially parallel to the length direction of the battery module 100, that is, the first direction is the x-axis direction, and the second direction is substantially perpendicular to the first direction, then the second direction is substantially parallel to the width direction of the battery module 100, that is, the second direction is the y-axis direction.
[0038] As Figure 2 and Figure 6 shown, the clamping member 123 has a first clamping surface 12321 and a second clamping surface 12331 arranged vertically. The space between the first clamping surface 12321 and the second clamping surface 12331 forms a clamping space. The top surface of the module upper cover 110 is arranged opposite to the first clamping surface 12321, and the bottom surface of the module upper cover 110 is arranged opposite to the second clamping surface 12331, that is, the first clamping surface 12321 and the second clamping surface 12331 are arranged opposite to both ends of the module upper cover 110 along the z-axis direction, so as to realize the limiting and fixing of the module upper cover 110 along the z-axis direction, so that the battery module 100 can withstand the vibration and shock in the z-axis direction.
[0039] For the specific structure of the clamping member 123, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6, which includes a limiting wall 1231, a hook 1232 and a support block 1233. Among them, the limiting wall 1231 extends upward from one end of the busbar bracket 122 in the first direction. The limiting wall 1231 has a first side surface 12311 that limits and abuts against the upper cover 110 of the module. When the upper cover 110 of the module is quickly assembled in place with the busbar bracket 122, one end of the upper cover 110 of the module in the first direction can limit and abut against the first side surface 12311; the hook 1232 protrudes inward from the first side surface 12311, and the hook 1232 is clamped with the upper cover 110 of the module, that is, the bottom of the hook 1232 has a first clamping surface 12321, so that the first clamping surface 12321 abuts against the top surface of the upper cover 110 of the module; the support block 1233 is arranged below the hook 1232 and is used to support the bottom surface of the upper cover 110 of the module, that is, the top of the support block 1233 has a second clamping surface 12331, so that the second clamping surface 12331 abuts against the bottom surface of the upper cover 110 of the module.
[0040] As Figures 1 to 6 shown, the limiting wall 1231 has a first side surface 12311 and a second side surface 12312 that are oppositely arranged in the first direction. The first side surface 12311 faces the upper cover 110 of the module, and the hook 1232 protrudes from the first side surface 12311 in a direction away from the second side surface 12312, realizing the clamping fit between the hook 1232 and the upper cover 110 of the module and preventing the upper cover 110 of the module from moving upward.
[0041] As Figure 3 and Figure 4 shown, one end of the upper cover 110 of the module in the first direction is provided with an avoidance notch 111, so that the limiting wall 1231 is inserted and loaded into the avoidance notch 111 along the first direction. The limiting wall 1231 can limit and abut against the edge of the avoidance notch 111 to prevent the hook 1232 from shaking at the avoidance notch 111, ensure the reliable clamping of the hook 1232 and the upper cover 110 of the module, and the stable support of the support block 1233 for the upper cover 110 of the module. At the same time, the second side surface 12312 does not protrude from the end surface of the upper cover 110 of the module in the first direction to prevent the vibration impact from clamping the member 123 and causing its damage.
[0042] As Figure 2 and Figure 6 shown, the hook 1232 is in a wedge shape or a conical shape with a smaller upper part and a larger lower part and gradually widening inward, which is more conducive to the movement of the hook 1232 relative to the avoidance notch 111 in the first direction to realize the clamping of the hook 1232 with the top surface of the upper cover 110 of the module at the edge of the avoidance notch 111, so that the upper cover 110 of the module is stably connected to the busbar bracket 122, improving the reliability of the connection. The inner surface of the hook 1232 is provided with an arc-shaped guiding surface 12322, making it easier for the upper cover 110 of the module to move into the clamping space, and the operation is convenient and labor-saving.
[0043] AsFigures 1 to 6 As shown, a clamping member 124 protruding upward and extending is provided on the bus bar bracket 122, and an assembly hole 112 for inserting and loading the clamping member 124 is formed on the upper cover 110 of the module, so that the upper cover 110 of the module and the bus bar bracket 122 are detachably connected through the insertion structure, which can not only firmly assemble the bus bar bracket 122 and the upper cover 110 of the module together, but also improve the assembly efficiency of the battery module 100.
[0044] Preferably, the clamping member 124 and the assembly hole 112 are in interference fit to prevent the upper cover 110 of the module from moving up and down along the z-axis direction, realizing multiple limit fixing of the upper cover 110 of the module along the z-axis direction, enhancing the reliability of the assembly of the upper cover 110 of the module and the bus bar bracket 122, and thus improving the working stability of the entire battery module 100.
[0045] As Figure 1 、 Figure 3 and Figure 5 shown, a plurality of clamping members 124 are arranged at intervals on the bus bar bracket 122 along the first direction, and assembly holes 112 for inserting and loading the corresponding clamping members 124 are formed at the corresponding positions on the upper cover 110 of the module, so that a plurality of insertion structures are arranged at intervals along the length direction of the battery module 100, ensuring that the connection strength between the upper cover 110 of the module and the bus bar bracket 122 is basically consistent along the length direction of the battery module 100.
[0046] As Figure 1 、 Figure 3 and Figure 5 shown, a plurality of clamping members 124 are arranged at intervals on the bus bar bracket 122 along the second direction, and assembly holes 112 for inserting and loading the corresponding clamping members 124 are formed at the corresponding positions on the upper cover 110 of the module, so that a plurality of insertion structures are arranged at intervals along the width direction of the battery module 100, ensuring that the connection strength between the upper cover 110 of the module and the bus bar bracket 122 is basically consistent along the width direction of the battery module 100.
[0047] As Figure 4 and Figure 6 shown, a limiting tooth 113 is formed by the edge of the assembly hole 112 extending towards the inside of the assembly hole 112, and a limiting hole 1243 for inserting and loading the limiting tooth 113 is formed on the clamping member 124, preventing the upper cover 110 of the module and the bus bar bracket 122 from moving relative to each other and causing them to separate, and further improving the limiting effect.
[0048] As Figure 2 and Figure 6As shown, the snap-in part 124 has a snap-in portion 1241 and a support portion 1242 arranged vertically. The snap-in portion 1241 is inserted into the assembly hole 112, the support portion 1242 protrudes outward from the snap-in portion 1241, and the cross-sectional area of the support portion 1242 is larger than the cross-sectional area of the assembly hole 112 for supporting on the bottom surface of the module upper cover 110.
[0049] As Figure 2 and Figure 6 shown, the bus bar bracket 122 is provided with a positioning post 125 protruding upward and extending. The module upper cover 110 is provided with a positioning hole for the positioning post 125 to be inserted into. Before the snap-in portion 1241 is inserted into the assembly hole 112, pre-positioning between the module upper cover 110 and the bus bar bracket 122 is achieved, further improving the assembly efficiency of the battery module 100.
[0050] Preferably, the second clamping surface 12331 of the support block 1233 and the top surface of the support portion 1242 are on the same horizontal plane, so that the module upper cover 110 is kept in a horizontal state, reducing the impact of vibration on the battery module 100 and ensuring the electrical safety of the battery module 100 during assembly, transportation, and normal operation.
[0051] As Figures 3 to 6 shown, at least two limiting teeth 113 are arranged oppositely in the second direction. The limiting hole 1243 penetrates through both ends of the snap-in part 124 in the second direction for at least two limiting teeth 113 to be inserted into the limiting hole 1243 in the second direction, preventing the module upper cover 110 from moving in the y-axis direction and achieving limiting and fixing of the module upper cover 110 in the y-axis direction, so that the battery module 100 can withstand vibration and impact in the y direction.
[0052] As Figure 5 and Figure 6 shown, the bus bar bracket 122 is provided with a buffer groove 1221 that is recessed downward and open upward. A plurality of buffer grooves 1221 are spaced along the first direction and / or the second direction, having the function of absorbing vibration and impact.
[0053] Preferably, the module upper cover 110 is provided with a sink that is recessed downward and open upward. A plurality of sinks are spaced along the first direction and / or the second direction on the module upper cover 110. The bottom of each sink is provided with an assembly hole 112 for the corresponding snap-in part 124 to be inserted into. By providing a sink on the module upper cover 110, the reliability of the assembly of the module upper cover 110 and the bus bar bracket 122 can be improved, and when producing the module upper cover 110, the thickness of the module upper cover 110 can be reduced, thereby avoiding restricting the increase in the height of the battery cell and further improving the energy density of the battery module 100.
[0054] As an embodiment not shown, a clamping member 124 protruding upward is provided on the bus bar bracket 122, and an upwardly recessed and downwardly open assembly groove is provided on the upper cover 110 of the module. The clamping member 124 is inserted into the assembly groove, so that the upper cover 110 of the module is detachably connected to the bus bar bracket 122 through the insertion structure, and the upper cover 110 of the module covers the surface of the clamping member 124 through the assembly groove, which not only helps to improve the assembly efficiency of the battery module 100, but also can protect the clamping member 124 from being damaged due to vibration and impact, thereby ensuring the stability of the battery module 100.
[0055] Preferably, a first limiting portion and a second limiting portion are provided on the side wall of the assembly groove and are oppositely arranged in the second direction. A through hole penetrating through both ends of the clamping member 124 in the second direction is formed on the clamping member 124, so that the first limiting portion and the second limiting portion are respectively inserted into the through hole to form a double limiting structure, preventing the upper cover 110 of the module from moving in the y-axis direction, realizing the limiting and fixing of the upper cover 110 of the module in the y-axis direction, so that the battery module 100 can withstand the vibration and impact in the y direction.
[0056] The disassembly and assembly process of the installation structure of the battery pack according to the embodiment of the present application will be described below with reference to the accompanying drawings.
[0057] As Figures 1 to 6 shown, when the upper cover 110 of the module is assembled with the bus bar bracket 122, first move the upper cover 110 of the module in the first direction so that the upper cover 110 of the module is limited in the clamping space, that is, one end of the upper cover 110 of the module in the first direction is in limiting contact with the support wall, realizing the limiting and fixing of the upper cover 110 of the module in the x-axis direction. The first clamping surface 12321 of the hook 1232 is in contact with the top surface of the upper cover 110 of the module, and the second sizing of the support block 1233 is in contact with the bottom surface of the upper cover 110 of the module, realizing the limiting and fixing of the upper cover 110 of the module in the x-axis direction. Then, the positioning post 125 penetrates through the upper cover 110 of the module to realize the pre-positioning between the upper cover 110 of the module and the bus bar bracket 122. Then, an external force is applied to the top surface of the upper cover 110 of the module, and the clamping member 124 is inserted into the assembly hole 112 and the limiting tooth 113 is inserted into the limiting hole 1243, realizing the limiting and fixing of the upper cover 110 of the module in the y-axis direction, so that the battery module 100 can be limited in three directions and is not prone to vibration failure problems in actual working conditions.
