Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model. In the utility model, unless otherwise stated, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0032] In the related art, in order to increase the capacity of the battery pack, the battery pack includes multiple battery modules, and the multiple battery modules are stacked and installed in a frame. Among them, the battery module is usually supported in the frame by a liquid cooling plate, and the liquid cooling plate has low strength and is easy to deform under the gravity of the battery module, thereby affecting the connection stability between the battery module and the frame. Moreover, the deformation of the liquid cooling plate may cause the internal cooling pipe to bend or even break, thereby affecting the performance of the liquid cooling plate, and may even cause the liquid cooling plate to leak.

[0033] In order to avoid the above problems, an embodiment of the present application provides a battery pack and a vehicle, which are described in detail as follows.

[0034] Figure 1 It is a structural schematic diagram of an embodiment of a battery pack provided in an embodiment of the present application. Figure 2 yes Figure 1 Cross-sectional view along AA direction. Figure 3 yes Figure 2 Enlarged view of point A in the middle. Figure 4 yes Figure 1 Cross-sectional view along direction BB. Figure 5 Schematic diagram of the decomposed structure of the frame and multiple battery modules provided in the embodiment of the present application. Figure 1 and Figure 2 As shown, the battery pack 100 includes a frame 110 and a plurality of battery modules 120, the frame 110 includes an installation cavity 1100, and the plurality of battery modules 120 are arranged in the installation cavity 1100 of the frame 110 along the height direction Z of the frame 110. Among them, the frame 110 includes a plurality of support structures, and the plurality of support structures are arranged along the height direction Z of the frame 110. The plurality of support structures are connected to the plurality of battery modules 120 in a one-to-one correspondence to support the plurality of battery modules 120. The plurality of support structures can be arranged in sequence along the height direction Z of the frame 110, or can be staggered along the height direction Z of the frame 110.

[0035] Continue to refer to Figure 2 The battery module 120 includes a frame 121 and a plurality of battery cells 122, and the plurality of battery cells 122 are installed in the frame 121. The plurality of battery cells 122 can be stacked along the first direction X. In some embodiments, a connection structure can be provided on the frame 121 of the battery module 120, and the connection structures of the plurality of frames 121 are connected to the plurality of support structures in a one-to-one correspondence, so that the plurality of support structures are connected to the plurality of battery modules 120 in a one-to-one correspondence.

[0036] The battery pack 100 provided in the embodiment of the present application is provided with a connection structure on the frame 121 of the battery module 120, and a plurality of support structures are provided in the frame 110 along the height direction Z of the frame 110, and the connection structures of the plurality of frames 121 are connected to the plurality of support structures one by one, so that the plurality of battery modules 120 are supported in the installation cavity 1100 of the frame 121. Since the frame 121 of the battery module 120 is stronger, it is not easy to deform under the action of the gravity of the battery module 120 itself, which is beneficial to improve the connection stability between the battery module 120 and the frame 110. Moreover, the battery module 120 is supported on the frame 110 by the frame 121, and the pressure on the liquid cooling plate of the battery module 120 is reduced, and the risk of deformation is also reduced, which is beneficial to improve the stability of the liquid cooling plate.

[0037] In some embodiments, Figures 2 to 4 As shown, the support structure provided on the frame 110 may include two support portions 1131 distributed on both sides of the installation cavity 1100 along a first direction X, and the first direction X forms an angle with the height direction Z of the frame 110. The angle formed by the first direction X and the height direction Z of the frame 110 may be a right angle or an acute angle.

[0038] Correspondingly, the connection structure provided on the frame 121 may include two connection parts 1213 distributed on both sides of the frame 121 along the first direction X, and the two connection parts 1213 of the connection structure are connected to the two support parts 1131 of the corresponding support structure in a one-to-one correspondence. Thus, the support structure supports both ends of the frame 121 along the first direction X, which is conducive to improving the connection stability between the support structure and the frame 121.

[0039] like Figures 2 to 4 As shown, the frame 121 includes two end plates 1211 disposed opposite to each other, and the two end plates 1211 are located on both sides of the plurality of battery cells 122 along the first direction X. The battery module 120 includes a plurality of battery cells 122 , and the plurality of battery cells 122 are disposed along the first direction X between the two end plates 1211 .

[0040] Among them, the battery module 120 also includes a cooling plate 123 and a cover plate 124, and the cooling plate 123 and the cover plate 124 are distributed on both sides of the multiple battery cells 122 along the height Z direction of the frame 110, and the cooling plate 123 is used to cool down the multiple battery cells 122. Among them, the two ends of the cooling plate 123 along the first direction X are connected to the two end plates 1211 in a one-to-one manner. The cooling plate 123 and the end plate 1211 can be connected by welding, or by screws or other methods. The cover plate 124 and the two end plates 1211 are connected in a one-to-one manner along the first direction X. The cover plate 124 and the end plate 1211 can be connected by welding, or by screws or other methods.

[0041] In other embodiments, the frame 121 may also include two side panels (not shown) arranged opposite to each other along the second direction Y, and the first direction X and the height direction Z of the frame 110 are respectively at an angle with the second direction Y. One end of the two side panels is connected to the two ends of one end plate 1211, and the other ends of the two side panels are connected to the two ends of another end plate 1211, so that the two side panels and the two end panels 1211 enclose a cavity for accommodating the battery cell 122.

[0042] In some embodiments, the connection portion 1213 of the connection structure can be protruded on the side of the end plate 1211 away from the battery cell 122. It can be understood that the strength of the end plate 1211 of the frame 121 is higher than that of other parts of the frame 121 and is less likely to deform. By protruding the connection portion 1213 of the connection structure on the side of the end plate 1211 away from the battery cell 122, the connection stability between the battery module 120 and the frame 110 can be further improved.

[0043] The connection portion 1213 and the end plate 1211 can be connected as one piece, thereby further improving the connection stability between the connection portion 1213 and the end plate 1211, making the connection portion 1213 and the end plate 1211 stronger, and making the connection between the battery module 120 and the frame 110 more stable. The connection portion 1213 and the end plate 1211 can be connected as one piece by welding, or the end plate 1211 and the connection portion 1213 can be formed at one time. Of course, the connection portion 1213 and the end plate 1211 can also be fixedly connected together by bolting, clamping, etc.

[0044] Specifically, the connection portion 1213 includes a plurality of connection protrusions 1214 protruding from the side of the end plate 1211 away from the battery cell 122 , and the plurality of connection protrusions 1214 are arranged along the second direction Y. The plurality of connection protrusions 1214 may be arranged in sequence along the second direction Y or distributed in a staggered manner.

[0045] Correspondingly, the frame 110 includes a support beam 111 extending along the second direction Y, and the support portion 1131 is arranged on the side of the support beam 111 facing the installation cavity 1100, and the first direction X and the height direction Z of the frame 110 are respectively at an angle with the second direction Y. The angles formed by the first direction X and the height direction Z of the frame 110 and the second direction Y can be a right angle or an acute angle. The support portion 1131 includes a plurality of support protrusions 1132 protruding from the side of the support beam 111 facing the installation cavity 1100, and the plurality of support protrusions 1132 are arranged along the second direction Y. Among them, the plurality of support protrusions 1132 are arranged in sequence or staggered along the second direction Y. The number of the plurality of connecting protrusions 1214 is equal to the number of the plurality of supporting protrusions 1132, and they are connected one by one, so that the connecting portion 1213 is connected to the supporting portion 1131.

[0046] The support part 1131 can be integrally connected with the support beam 111, or the support part 1131 can be installed on the support beam 111 by bolting, clamping, etc. Of course, the former can further improve the connection stability between the support part 1131 and the support beam 111 and the strength of the support part 1131.

[0047] In the embodiment of the present application, the connection structure can be arranged above the supporting structure, or below the supporting structure, or the connection structure and the supporting structure can be distributed along the first direction X or the second direction Y, as long as the connection structure can be stably connected to the supporting structure. Of course, by arranging the connection structure above or below the supporting structure, it is helpful to reduce the width of the frame 110 in the first direction X.

[0048] In some embodiments, Figures 2 to 4 As shown, the connection portion 1213 of the connection structure can be located above or below the support portion 1131 of the support structure, and a locking member can pass through the connection portion 1213 and the support portion 1131 to fix the connection portion 1213 and the support portion 1131 together.

[0049] In some embodiments, the frame 110 may include a plurality of limiting structures 114, and the plurality of limiting structures 114 may be arranged in sequence along the height direction Z of the frame 110. The plurality of limiting structures 114 are arranged one-to-one correspondingly to the plurality of battery modules 120, and the limiting structure 114 includes two limiting portions 1141 distributed on both sides of the frame 121 along the first direction X, and the two limiting portions 1141 are used to abut against both sides of the frame 121 along the first direction X, thereby limiting the deformation of the frame 121 in the first direction X, and further limiting the expansion deformation of the battery cell 122 in the first direction X.

[0050] The two end plates 1211 of the frame 110 are arranged opposite to each other along the first direction X. The two stoppers 1141 are used to abut against the two end plates 1211 in a one-to-one correspondence, so as to prevent the battery cells 122 from expanding and deforming and squeezing the end plates 1211, causing the end plates 1211 to be greatly bent and deformed.

[0051] In some embodiments, the limiting portion 1141 can be used to abut against the middle portion of the end plate 1211 along the second direction Y, so as to further improve the limiting effect of the limiting portion 1141 on the deformation of the end plate 1211. Specifically, the limiting portion 1141 is arranged on the side of the support beam 111 facing the installation cavity 1100, and the limiting portion 1141 is located in the middle portion of the support beam 111 along the second direction Y, so that the limiting portion 1141 can abut against the middle portion of the end plate 1211 along the second direction Y. Among them, the limiting portion 1141 and the support beam 111 can be connected as a whole, or they can be fixedly connected by bolt fixing, clamping, etc. Of course, the former can further improve the connection stability between the limiting portion 1141 and the support beam 111 and the strength of the support portion 1131, thereby further improving the limiting effect of the limiting portion 1141 on the end plate 1211.

[0052] In some embodiments, Figure 5 As shown, a first mounting opening 1101 connected to the mounting cavity 1100 can be opened at the top of the frame 110, and the first mounting opening 1101 is used for allowing the battery module 120 located at the top among the multiple battery modules 120 to be installed in the mounting cavity 1100, so as to facilitate the installation of the battery module 120 located at the top among the multiple battery modules 120 in the mounting cavity 1100.

[0053] It is understandable that, due to the presence of the cross beams 112 around the top of the frame 110, if the battery module 120 located at the top among the multiple battery modules 120 is installed in the installation space of the frame 110 along the first direction X or the second direction Y, it will be interfered by the cross beams 112, resulting in inconvenience in the installation of the battery module 120. However, by providing a first installation opening 1101 connected to the installation cavity 1100 at the top of the frame 110, the battery module 120 located at the top among the multiple battery modules 120 will not be interfered by the cross beams 112 when it is installed into the installation cavity 1100 from the first installation opening 1101 at the top of the frame 110, thereby making it more convenient to install the battery module 120 located at the top among the multiple battery modules 120.

[0054] Among them, the connection structure of the battery module 120 located at the top can be supported on the top of the corresponding support structure. Therefore, when the battery module 120 located at the top of the multiple battery modules 120 is installed from the first installation port 1101 at the top of the frame 110 into the installation cavity 1100, the connection structure of the battery module 120 located at the top can be directly supported on the top of the corresponding support structure, and the battery module 120 does not need to be positioned by other tools, and the connection structure can be easily connected to the corresponding support structure, which is very convenient to operate.

[0055] In some embodiments, a second mounting opening 1102 connected to the mounting cavity 1100 may be provided at the bottom of the frame 110. The second mounting opening 1102 is used for allowing the battery module 120 located at the bottom to be installed in the mounting cavity 1100, so as to facilitate installing the battery module 120 located at the bottom among multiple battery modules 120 in the mounting cavity 1100.

[0056] It is understandable that, due to the presence of the cross beams 112 around the bottom of the frame 110, when the battery module 120 located at the bottom among the multiple battery modules 120 is installed in the installation space of the frame 110 along the first direction X or the second direction Y, it will be interfered by the cross beams 112, resulting in inconvenience in installing the battery module 120. However, by providing a second installation opening 1102 connected to the installation cavity 1100 at the bottom of the frame 110, when the battery module 120 located at the bottom among the multiple battery modules 120 is installed into the installation cavity 1100 from the second installation opening 1102 at the bottom of the frame 110, it will not be interfered by the cross beams 112, thereby making it more convenient to install the battery module 120 located at the bottom among the multiple battery modules 120.

[0057] The connection structure of the battery module 120 at the bottom can be connected to the bottom of the corresponding support structure. Therefore, when the battery module 120 at the bottom of the plurality of battery modules 120 is installed into the installation cavity 1100 from the second installation opening 1102 at the bottom of the frame 110, the connection structure of the battery module 120 at the bottom can be directly connected to the bottom of the corresponding support structure, and the connection structure can be easily connected to the corresponding support structure without positioning the battery module 120 using other tools, which is very convenient to operate.

[0058] In some embodiments, Figure 5As shown, the frame 110 may be provided with a third installation opening 1103 in communication with the installation cavity 1100 on one side along the second direction Y, and the third installation opening 1103 is used for the battery module 120 to be installed in the installation cavity 1100. Thus, other battery modules 120 located outside the top and bottom battery modules 120 among the multiple battery modules 120 may be conveniently installed in the installation cavity 1100 from the third installation opening 1103. The connection structure of the battery module 120 installed in the installation cavity 1100 from the third installation opening 1103 may be connected to the bottom of the corresponding support structure, or may be supported on the top of the corresponding support structure, which is not limited here.

[0059] In some embodiments, Figure 1 and Figure 2 As shown, a sealing plate 130 can be provided on each side of the frame 110. The sealing plates 130 on each side of the frame 110 can enclose a space with good sealing properties to protect the water pipes, wiring harnesses and other components in the frame 110, reduce the exposure of the water pipes, wiring harnesses and other components, and reduce the risks of corrosion, loosening or leakage of the components.

[0060] In some embodiments, the battery pack 100 may include a connector (not shown in the figure) for electrically connecting to an electrical device. The connector is electrically connected to multiple battery modules 120, so that multiple battery modules 120 share a set of connectors, which is beneficial to reducing the cost of the battery pack. Among them, the electrical components (not shown in the figure) of multiple battery modules 120 can be connected in series and then electrically connected to the connector, or the electrical components of multiple battery modules 120 can be connected in parallel and then electrically connected to the connector. The connector can be provided on the sealing plate 130 to facilitate the electrical connection of the electrical device to the connector.

[0061] An embodiment of the present application also provides a vehicle, which includes a battery pack. The specific structure of the battery pack refers to the various embodiments of the above-mentioned battery pack. Since the vehicle adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0062] The vehicle provided in the embodiment of the present application is provided with a connection structure on the frame 121 of the battery module 120 of the battery pack 100, and a plurality of support structures are provided in the frame 110 along the height direction Z of the frame 110, and the connection structures of the plurality of frames 121 are connected to the plurality of support structures in a one-to-one correspondence, so that the plurality of battery modules 120 are supported in the installation cavity 1100 of the frame 121. Since the frame 121 of the battery module 120 is stronger, it is not easy to deform under the action of the gravity of the battery module 120 itself, which is beneficial to improve the connection stability between the battery module 120 and the frame 110. Moreover, the battery module 120 is supported on the frame 110 by the frame 121, and the pressure on the liquid cooling plate of the battery module 120 is reduced, and the risk of deformation is also reduced, which is beneficial to improve the stability of the liquid cooling plate.
