[0003] In batteries, the base plate of the battery frame assembly is usually set as a liquid cooling plate. The liquid cooling plate has heat exchange channels, in which the heat exchange medium flows and exchanges heat with the battery cells to achieve battery temperature control.

[0004] To facilitate the input and output of the heat exchange medium, the frame assembly is also equipped with a liquid inlet and a liquid outlet. The liquid inlet is connected to the liquid inlet, which communicates with the heat exchange channel, and the liquid outlet is connected to the liquid outlet, which also communicates with the heat exchange channel. Since the liquid inlet, liquid outlet, liquid inlet connector, and liquid outlet connector are all located within the housing cavity of the frame assembly, the external input connector and external output connector need to be connected to the liquid inlet connector and liquid outlet connector respectively through additional pipelines. This increased pipeline design increases the risk of heat exchange medium leakage. Utility Model Content

[0054] Currently, judging from market trends, battery applications are becoming increasingly widespread. Batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also extensively in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. With the continuous expansion of battery applications, market demand is also constantly increasing.

[0055] In batteries, the base plate of the battery frame assembly is usually set as a liquid cooling plate. The liquid cooling plate has heat exchange channels, in which the heat exchange medium flows and exchanges heat with the battery cells to achieve battery temperature control.

[0056] To facilitate the input and output of the heat exchange medium, the frame assembly is also equipped with a liquid inlet and a liquid outlet. The liquid inlet is connected to the liquid inlet, which communicates with the heat exchange channel, and the liquid outlet is connected to the liquid outlet, which also communicates with the heat exchange channel. Since the liquid inlet, liquid outlet, liquid inlet connector, and liquid outlet connector are all located within the housing cavity of the frame assembly, the external input connector and external output connector need to be connected to the liquid inlet connector and liquid outlet connector respectively through additional pipelines. This increased pipeline design increases the risk of heat exchange medium leakage.

[0057] Please see Figures 1 to 5To alleviate the aforementioned problems, this application provides a frame assembly 100, which includes a base plate 10, a frame 20, and a cover plate. The frame 20 is a hollow structure with openings at both ends. The base plate 10 and the cover plate cover the openings at both ends of the frame 20, and together with the frame 20, define a cavity for accommodating a battery cell. The base plate 10 includes a connected main body 11 and an inlet / outlet liquid section 12, which are arranged along the length direction X or the width direction Y of the base plate 10. A heat exchange channel 13 for supplying heat exchange fluid is provided in both the main body 11 and the inlet / outlet liquid section 12. The inlet / outlet liquid section 12 is provided with an inlet 121 and an outlet 122, and the heat exchange channel 13 connects the inlet 121 and the outlet 122. The frame 20 is arranged circumferentially around the main body 11. At least a portion of the inlet / outlet liquid section 12 with an inlet 121 and an outlet 122 is exposed outside the frame 20.

[0058] The base plate 10 includes an upper base plate 14 and a lower base plate 15 disposed opposite each other along its thickness direction Z. The upper base plate 14 and the lower base plate 15 are combined to form the main body 11 and the liquid inlet / outlet section 12. The upper base plate 14 and the lower base plate 15 have approximately the same outline and can both be formed of aluminum sheet. For example, the upper base plate 14 is an aluminum sheet with a thickness of 1.5 mm, and the lower base plate 15 is an aluminum sheet with a thickness of 1.0 mm. The lower base plate 15 has a stamping feature, and the upper base plate 14 covers the lower base plate 15 and is welded to the lower base plate 15 by a brazing process to define a heat exchange channel 13 with the stamping feature. The heat exchange channel 13 is used to flow the heat exchange medium, which can be water, alcohol, or a liquid capable of heat exchange.

[0059] The upper base plate 14 has a first connecting hole 141 in the non-edge area, and the lower base plate 15 has a second connecting hole 151 in the non-edge area. The first connecting hole 141 and the second connecting hole 151 are positioned to avoid stamping features. Both the first connecting hole 141 and the second connecting hole 151 are located in the main body 11. The inner beam 23 of the frame 20 has a third connecting hole. The frame assembly 100 also includes connectors. The first connecting hole 141, the second connecting hole 151, and the third connecting hole correspond one-to-one with the connectors. The connectors pass through the corresponding first connecting hole 141, second connecting hole 151, and third connecting hole to achieve the connection between the frame 20 and the main body 11. Furthermore, to improve sealing, the edge area of ​​the frame 20 and the main body 11 can also be sealed together using processes such as brazing or friction welding.

[0060] Specifically, the first connecting hole 141, the second connecting hole 151, and the third connecting hole can be, but are not limited to, rivet screw holes, and the connector can be, but is not limited to, a rivet screw. The specific configuration can be determined according to requirements.

[0061] It can be understood that the non-edge area of ​​the upper base plate 14 is the area formed by the edge area of ​​the upper base plate 14, and the non-edge area of ​​the lower base plate 15 is the area formed by the lower base plate 15.

[0062] The frame 20 may be, but is not limited to, made of aluminum alloy. The frame 20 typically includes side beams and inner beams 23. The side beams are beam structures surrounding the outer contour of the frame 20, typically including two transverse side beams 21 and two longitudinal side beams 22. The two transverse side beams 21 are spaced apart along the length direction X of the base plate 10, and the two longitudinal side beams 22 are spaced apart along the width direction Y of the base plate 10. The inner beams 23 are beam structures located within the area formed by the two transverse side beams 21 and the two longitudinal side beams 22. The inner beams 23 serve to divide space, enhance mechanical strength, and install components. The number and arrangement of the inner beams 23 can be determined according to requirements. For example, ... Figure 1 For example, there are two inner beams 23, which are spaced apart along the length direction X of the bottom plate 10, and both inner beams 23 are connected between the two longitudinal side beams 22.

[0063] The arrangement of the first connecting hole 141 in the upper base plate 14 and the second connecting hole 151 in the lower base plate 15 is the same as that of the inner beam 23. Figure 1 There are two inner beams 23, which are spaced apart along the length direction X of the bottom plate 10. For example, both inner beams 23 are connected between the two longitudinal side beams 22. Each inner beam 23 is provided with a row of third connecting holes arranged along its extension direction. The upper bottom plate 14 has two rows of first connecting holes 141 and the lower bottom plate 15 has two rows of second connecting holes 151. The two rows of first connecting holes 141 and the two rows of second connecting holes 151 correspond one-to-one with the two rows of third connecting holes of the two inner beams 23.

[0064] Taking the main body 11 and the liquid inlet / outlet 12 as an example arranged along the length direction X of the base plate 10, the liquid inlet / outlet 12 extends out of the frame 20 along the length direction X of the base plate 10. Taking the main body 11 and the liquid inlet / outlet 12 as an example arranged along the width direction Y of the base plate 10, the liquid inlet / outlet 12 extends out of the frame 20 along the width direction Y of the base plate 10.

[0065] The liquid inlet / outlet section 12 has at least a liquid inlet 121 and a liquid outlet 122 exposed outside the frame 20. As an example, the liquid inlet / outlet section 12 may be completely exposed outside the frame 20, or the liquid inlet / outlet section 12 may only have a liquid inlet 121 and a liquid outlet 122 exposed outside the frame 20, with the rest located inside the frame 20.

[0066] The liquid inlet / outlet section 12, with at least an inlet 121 and an outlet 122, is exposed outside the frame 20, and thus the inlet 121 and outlet 122 are also exposed outside the frame 20. Therefore, the external input connector 200 can be directly connected to and communicate with the inlet 121, or it can be connected to and communicate with the inlet 121 via an external inlet connector 30. Similarly, the external output connector 300 can be directly connected to and communicate with the outlet 122, or it can be connected to and communicate with the outlet 122 via an external outlet connector 40. With this design, no additional piping is required between the inlet 121 and the external input connector 200, or between the outlet 122 and the external output connector 300, reducing the piping layout within the frame assembly 100, improving the space utilization of the frame assembly 100, and reducing the number of piping connection paths, thereby reducing the risk of heat exchange medium leakage and contamination of the battery interior.

[0067] In some embodiments, the frame assembly 100 includes an inlet connector 30 and an outlet connector 40, which are exposed outside the frame 20. The inlet connector 30 is fitted to and communicates with the inlet port 121, and the outlet connector 40 is fitted to and communicates with the outlet port 122.

[0068] As an example, both the inlet connector 30 and the outlet connector 40 can be, but are not limited to, aluminum connectors.

[0069] By setting up the inlet connector 30 and the outlet connector 40, it is convenient to directly connect the external input connector 200 to the inlet connector 30 and the external output connector 300 to the outlet connector 40, thereby improving the installation efficiency of the external input connector 200 and the external output connector 300.

[0070] Please see Figures 3 to 9 In some embodiments, the frame assembly 100 further includes a connector beam 50, which is exposed outside the frame 20 and connected to the inlet / outlet liquid section 12. The inlet connector 30, the outlet connector 40, the connector beam 50 and the frame 20 all protrude from the top side of the base plate 10 along the thickness direction Z, so that the space occupied by the inlet connector 30, the outlet connector 40, the connector beam 50 and the frame 20 in the thickness direction Z of the base plate 10 overlaps, which helps to reduce the space occupied by the frame assembly 100 in the thickness direction Z of the base plate 10 and improve the space utilization rate of the frame assembly 100. The connector beam 50 has a through-hole inlet mounting hole 51 and an outlet mounting hole 52. The inlet connector 30 and the external input connector 200 are installed facing each other in the inlet mounting hole 51, and the external input connector 200 is connected and communicates with the inlet connector 30. The outlet connector 40 and the external output connector 300 are installed facing each other in the outlet mounting hole 52, and the external output connector 300 is connected and communicates with the outlet connector 40.

[0071] The joint beam 50 and the inlet / outlet liquid section 12 can be connected by brazing, friction welding or other methods.

[0072] The connector beam 50 is provided with an inlet mounting hole 51 and an outlet mounting hole 52. The inlet connector 30 and the external input connector 200 can be positioned and limited through the inlet mounting hole 51 to facilitate the connection between the inlet connector 30 and the external input connector 200. The outlet connector 40 and the external output connector 300 can be positioned and limited through the outlet mounting hole 52 to facilitate the connection between the outlet connector 40 and the external output connector 300.

[0073] In addition, to reduce the weight of the frame assembly 100, the joint beam 50 can be configured as a hollow beam structure with a cavity 56 inside.

[0074] Please see Figure 5 , Figures 8 to 12 In some embodiments, the connector beam 50 includes a first section 53 and a second section 54. The second section 54 is disposed away from the main body 11 relative to the first section 53, and the second section 54 protrudes from the bottom side of the first section 53 along the thickness direction Z of the bottom plate 10, and defines a groove 55 with the first section 53. The liquid inlet / outlet section 12 is disposed in the groove 55.

[0075] Taking the main body 11 and the liquid inlet / outlet section 12 as arranged along the length direction X of the base plate 10 as an example, the first section 53 and the second section 54 are also arranged along the length direction X of the base plate 10, and the second section 54 is arranged away from the main body 11 in this direction relative to the first section 53. The liquid inlet / outlet section 12 is inserted into the groove 55 along the length direction X of the base plate 10, and when it abuts against the second section 54 in this direction, the positioning and installation of the liquid inlet / outlet section 12 and the connector beam 50 are realized.

[0076] Taking the main body 11 and the liquid inlet / outlet section 12 as arranged along the width direction Y of the base plate 10 as an example, the first section 53 and the second section 54 are also arranged along the width direction Y of the base plate 10, and the second section 54 is arranged away from the main body 11 in this direction relative to the first section 53. The liquid inlet / outlet section 12 is inserted into the groove 55 along the width direction Y of the base plate 10, and when it abuts against the second section 54 in this direction, the positioning and installation of the liquid inlet / outlet section 12 and the connector beam 50 are realized.

[0077] By providing the groove 55, it is convenient to position and install the liquid inlet / outlet section 12 and the connector beam 50, so as to facilitate subsequent connection of the liquid inlet / outlet section 12 and the connector beam 50. In addition, the groove 55 can also achieve at least partial overlap of the liquid inlet / outlet section 12 and the connector beam 50 in the thickness direction Z of the base plate 10, saving space design of the frame assembly 100 and improving the space utilization of the frame assembly 100.

[0078] In some embodiments, the liquid inlet / outlet section 12 is positioned opposite to the bottom surface of the first section 53 in the thickness direction Z of the base plate 10, and protrudes from the second section 54 and is flush with the bottom surface of the first section 53.

[0079] The liquid inlet / outlet section 12 faces away from the bottom surface of the first section 53 in the thickness direction Z of the base plate 10, which is the bottom surface of the lower base plate 15 facing away from the bottom surface of the upper base plate 14.

[0080] The liquid inlet / outlet section 12 faces away from the bottom surface of the first segment 53 in the thickness direction Z of the base plate 10, and is flush with the bottom surface of the second segment 54, which protrudes from and is away from the bottom surface of the first segment 53. That is, the thickness of the base plate 10 is equal to the depth of the groove 55, which is also the sum of the thicknesses of the upper base plate 14 and the lower base plate 15 (e.g., Figure 8 (as shown in H1) and the depth of groove 55 (as shown in H1) Figure 12 (As shown in H2) is equal. It is worth mentioning that the thickness mentioned here refers to the thickness of the part without stamping features. For example, the height of the groove 55 is 2.5mm, the thickness of the upper base plate 14 is 1.5mm, the thickness of the lower base plate 15 is 1.0mm, and the sum of the thicknesses of the base plate 10 formed by brazing the upper base plate 14 and the lower base plate 15 is 2.5mm. Similarly, the thickness of the liquid inlet / outlet part 12 is also 2.5mm. The liquid inlet / outlet part 12 extends into the groove 55. When the liquid inlet / outlet part 12 faces away from the bottom surface of the first section 53 in the thickness direction Z of the base plate 10 and is flush with the bottom surface of the second section 54 that protrudes away from the bottom surface of the first section 53, the space between the liquid inlet / outlet part 12 and the joint beam 50 in the thickness direction Z of the base plate 10 completely overlaps, further improving the space utilization of the frame assembly 100. Furthermore, this design makes the bottom sides of both the liquid inlet / outlet section 12 and the connector beam 50 relatively flat, so that other components, such as the bottom guard plate 60, can be installed on the bottom sides of the liquid inlet / outlet section 12 and the connector beam 50.

[0081] Please see Figure 1 and Figure 3 ,as well as Figures 6 to 8 In some embodiments, the frame assembly 100 further includes a bottom guard plate 60, which is disposed on the bottom side of the frame 20 and the bottom plate 10 along the thickness direction Z of the bottom plate 10, and the bottom guard plate 60 is fastened to the frame 20 and the second segment 54.

[0082] As an example, the bottom guard plate 60 may be formed using, but is not limited to, high-strength steel of 0.8 mm.

[0083] The bottom protective plate 60 completely covers the bottom plate 10. The bottom protective plate 60 can support and protect the bottom plate 10, reducing the risk of deformation of the bottom plate 10 due to pressure from battery cells or external impact.

[0084] In some embodiments, a cushioning foam 70 may be provided between the bottom protective plate 60 and the bottom plate 10. The cushioning foam 70 serves a cushioning function, providing cushioning and force support for the bottom plate 10 to prevent it from bulging and deforming outward under the pressure of the battery cells. In addition, the cushioning foam 70 usually also has a heat insulation function. The low thermal conductivity of the cushioning foam 70 can also improve the heat preservation effect of the bottom plate 10 to adapt to low-temperature operating conditions.

[0085] In some embodiments, the bottom protective plate 60 is coated with a 1.0mm PVC (polyvinyl chloride) coating on the bottom surface facing away from the bottom plate 10, which serves to prevent corrosion, prevent stone impact, and reduce noise.

[0086] Please see Figure 1 and Figure 3 , Figures 6 to 12 As shown, in some embodiments, the top surface of the first segment 53 facing away from the liquid inlet / outlet section 12 is provided with a first fastening hole 531 and a second fastening hole 532. The first fastening hole 531 is located on the periphery of the liquid inlet mounting hole 51, and the second fastening hole 532 is located on the periphery of the liquid outlet mounting hole 52.

The specific settings can be made according to the requirements.

[0088] The first fastening hole 531 and the second fastening hole 532 can be configured in various ways. For example, the first fastening hole 531 can be two holes arranged along the length direction X or width direction Y of the base plate 10 on opposite sides of the liquid inlet mounting hole 51; or, the first fastening hole 531 can be multiple holes spaced apart along the periphery of the liquid inlet mounting hole 51. The second fastening hole 532 can be two holes arranged along the length direction X or width direction Y of the base plate 10 on opposite sides of the liquid outlet mounting hole 52; or, the second fastening hole 532 can be multiple holes spaced apart along the periphery of the liquid outlet mounting hole 52. By providing the first fastening hole 531, the second fastening hole 532, the first fastener 90, and the second fastener 110, the external input connector 200 and the external output connector 300 can be easily installed and fixed. By providing the third fastening hole 541, the fourth fastening hole 61, and the third fastener 120, the bottom guard plate 60 and the frame 20 can be easily installed and fixed.

[0089] To improve the stability of the installation between the bottom guard plate 60 and the frame 20, multiple fifth fastening holes 24 are provided on the transverse beam 21 and longitudinal beam 22 of the frame 20. All the fifth fastening holes 24 are arranged around the circumference of the frame 20. Multiple sixth fastening holes 62 are provided on the bottom guard plate 60.

[0090] Please see Figure 2 In some embodiments, a sealing gasket 80 is also provided between the bottom protective plate 60 and the frame 20. The sealing gasket 80 abuts against the bottom protective plate 60 and the frame 20 and is used to seal the gap between the bottom protective plate 60 and the frame 20 to reduce the risk of external moisture entering the frame 20 and coming into contact with the battery cells.

[0091] Please see Figures 1 to 5 ,as well as Figures 13 to 15 In some embodiments, the side beams of the frame 20 are provided with outlet grooves 211, the liquid inlet / outlet section 12 and the connector beam 50 are engaged with the outlet grooves 211 and extend out of the frame 20 through the outlet grooves 211.

[0092] Taking the main body 11 and the liquid inlet / outlet 12 as an example, which are arranged and connected along the length direction X of the base plate 10, a lead-out groove 211 is provided on a horizontal side beam 21. In the width direction Y of the base plate 10, the dimensions of the lead-out groove 211, the dimensions of the liquid inlet / outlet 12, and the dimensions of the connector beam 50 are the same, so as to realize the snap-fit ​​between the liquid inlet / outlet 12 and the connector beam 50 and the lead-out groove 211.

[0093] In some other embodiments, taking the main body 11 and the liquid inlet / outlet 12 as an example, which are arranged and connected along the width direction Y of the base plate 10, an outlet groove 211 is provided on a longitudinal side beam 22. In the length direction X of the base plate 10, the dimensions of the outlet groove 211, the liquid inlet / outlet 12 and the connector beam 50 are the same, so as to realize the snap-fit ​​between the liquid inlet / outlet 12 and the connector beam 50 and the outlet groove 211.

[0094] The setting of the outlet groove 211 helps to achieve the avoidance design between the liquid inlet / outlet section 12 and the connector beam 50 and the frame 20, and avoids interference between the liquid inlet / outlet section 12 and the connector beam 50 and the frame 20, which would hinder the installation of the liquid inlet / outlet section 12, the connector beam 50 and the frame 20.

[0095] In addition, to improve sealing, the gap between the joint beam 50 and the wall of the outlet groove 211, as well as the gap between the inlet / outlet liquid section 12 and the wall of the outlet groove 211, can be sealed by welding.

[0096] Please see Figure 5 In some embodiments, the main body 11 and the liquid inlet / outlet section 12 are arranged and connected along the length direction X of the base plate 10, and the dimensions of the liquid inlet / outlet section 12 in the width direction Y of the base plate 10 are (e.g., ... Figure 5 (As shown in H4) is smaller than the size of the main body 11 (e.g.) Figure 5 As shown in H3, this reduces the design of the base plate 10 material and lowers the manufacturing cost of the frame assembly 100.

[0097] Of course, in some other embodiments, the main body 11 and the liquid inlet / outlet 12 may be arranged and connected along the width direction Y of the base plate 10, and the size of the liquid inlet / outlet 12 is smaller than the size of the main body 11 in the length direction X of the base plate 10.

[0098] This application also provides a battery, which includes a plurality of battery cells and a frame assembly 100 as described in any of the above embodiments. The frame assembly 100 further includes a cover plate, a bottom plate 10, the cover plate and the frame 20 defining a receiving cavity, in which all battery cells are disposed.

[0099] The battery in this application has the effects of any of the above embodiments, so it will not be described again here.

[0100] In the aforementioned frame assembly 100 and the battery including it, the portion of the liquid inlet / outlet section 12, which has at least an inlet 121 and an outlet 122, is exposed outside the frame 20. Therefore, the inlet 121 and outlet 122 are also exposed outside the frame 20. Thus, the external input connector 200 can be directly connected to and communicate with the inlet 121, or it can be connected to and communicate with the inlet 121 via an external liquid inlet connector 30. Similarly, the external output connector 300 can be directly connected to and communicate with the outlet 122, or it can be connected to and communicate with the outlet 122 via an external liquid outlet connector 40. With this design, no additional piping is required between the inlet 121 and the external input connector 200, or between the outlet 122 and the external output connector 300, reducing the piping layout within the frame assembly 100, improving the space utilization of the frame assembly 100, and reducing the risk of heat exchange medium leakage and contamination of the battery interior.

[0101] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
