[0005] In the above technical solution, by arranging a reinforcing beam between the two second beams of the bottom frame, the structural strength of the bottom frame can be improved, and the reinforcing beam can be used to support the batteries arranged between the two second beams, so as to increase the supporting area of ​​the batteries located between the two second beams, thereby improving the supporting strength, stability and reliability of the bottom frame for the batteries between the two second beams, and the batteries located between the two second beams are connected to the reinforcing beam, which can improve the stability and reliability of battery installation, and can improve the overall structural strength and stability of the battery assembly; and by arranging the reinforcing beam to include a mounting beam and a reinforcing cross beam connected to both ends of the mounting beam, the reinforcing beam is formed into an I-beam, so that the overall structural strength of the reinforcing beam is higher, which can better improve the structural strength of the battery supporting bracket, reduce the risk of damage to the battery supporting bracket, provide stable and reliable support for the battery, and the battery assembly has higher overall structural strength and higher stability.

[0006] In some embodiments, the second beam is connected to an adjacent one of the batteries.

[0007] In the above technical solution, connecting the second beam to the adjacent battery can further improve the stability and reliability of battery installation, and can make the overall structural strength and stability of the battery assembly higher.

[0008] In some embodiments, the battery supporting bracket includes a first support beam and a second support beam, the first support beam is connected to the upper surface of the second beam and extends along a first direction, the second support beam is connected to the upper surface of the mounting beam and extends along the first direction, and a storage space for accommodating the battery is defined between the first support beam and the second support beam.

[0009] In the above technical solution, by setting the first support beam and the second support beam, the structural strength of the battery supporting bracket can be further improved, thereby improving the stability and reliability of the battery supporting bracket for the battery; and, the battery is accommodated in the space defined by the first support beam and the second support beam, and the installation of the battery can be limited by the first support beam and the second support beam, which facilitates the installation of the battery and makes the installation of the battery more stable.

[0010] In some embodiments, the first support beam and the second beam are connected by welding or formed as one piece, and the second support beam and the mounting beam are detachably connected.

[0011] In the above technical solution, by making the second support beam and the mounting beam detachably connected, the second support beam can be formed into a detachable movable beam, which is convenient for the installation of the battery and the second support beam, and also convenient for the disassembly and assembly of the battery located between the first support beam and the second support beam; while the second support beam and the mounting beam are detachably connected, the first support beam and the second beam are welded or integrally formed, which can ensure the stability and reliability of the connection between the first support beam and the second beam, thereby facilitating the disassembly and assembly of the battery located between the first support beam and the second support beam, and making the overall structure relatively stable; in addition, the second support beam is located between the two first support beams. Since the second support beam is a movable beam, the amplitude at the second support beam is larger than the amplitude at the first support beam. By setting an I-shaped reinforcement beam, it can be used to limit the amplitude at this location, thereby improving the structural strength of the battery support bracket and reducing the risk of failure of the battery support bracket.

[0012] In some embodiments, a projection of the battery located between the first support beam and the second support beam on a horizontal plane partially overlaps with a projection of the second support beam on a horizontal plane.

[0013] In the above technical solution, the projection of the battery located between the first support beam and the second support beam on the horizontal plane partially overlaps with the projection of the second support beam on the horizontal plane, which can reduce the occupied space in the horizontal direction, make the structure of the battery assembly more compact, reduce space waste, improve space utilization, and help to improve the energy density of the battery assembly.

[0014] In some embodiments, the battery has a mounting portion, the mounting portion is supported on an upper surface of the mounting beam and is detachably connected to the mounting beam, and the second support beam is supported on an upper surface of the mounting portion and is detachably connected to the mounting portion.

[0015] In the above technical solution, the battery is connected to the mounting beam by setting a mounting portion, which facilitates the connection between the battery and the mounting beam, so that the mounting portion of the battery is detachably connected to the mounting beam and the second support beam is located on the upper surface of the mounting portion and is detachably connected to the mounting portion, so that the second support beam is formed into a detachable movable beam, which facilitates the installation of the battery and the second support beam, and also facilitates the disassembly and assembly of the battery located between the first support beam and the second support beam.

Not only can the bottom frame transmit the force it receives to the connecting frame, but the force received by the reinforcing beam and the first support beam can also be transmitted to the connecting frame. In this way, the force received by the entire battery support bracket can be transmitted to the connecting frame through multiple paths, so that the overall force received by the battery support bracket is dispersed, reducing the risk of damage to the battery support bracket.

[0018] In some embodiments, the second support beam is detachably connected to the mounting beam, and an end portion of the second support beam along the first direction is spaced apart from the connecting frame.

Since there is a gap between the end of the second support beam along the first direction and the connecting frame, the interference between the second support beam and the connecting frame during the disassembly and assembly process can also be reduced, which can make the disassembly and assembly of the second support beam more convenient and smooth.

[0020] In some embodiments, the reinforcing beam includes a first angle beam, which is arranged at a first corner between the reinforcing cross beam and the mounting beam, and the first angle beam is connected to both the reinforcing cross beam and the mounting beam; and / or, the reinforcing beam includes a second angle beam, which is arranged at a second corner between the reinforcing cross beam and the second beam, and the second angle beam is connected to both the reinforcing cross beam and the second beam.

[0060] A battery assembly 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0061] Reference Figure 1-Figure 3 In the first aspect, an embodiment of the utility model provides a battery assembly 100, including: batteries 20 and a battery supporting bracket 10, wherein the number of the batteries 20 is at least two, the battery supporting bracket 10 is used to support the batteries 20, and the battery supporting bracket 10 includes a bottom frame 11 and a reinforcing beam 14, and the reinforcing beam 14 is arranged on the bottom frame 11.

[0062] The bottom frame 11 includes two first beams 111 that are opposite to each other in the first direction and extend in the second direction, and two second beams 112 that are opposite to each other in the second direction and extend in the first direction, and both ends of each second beam 112 in the first direction are respectively connected to the two first beams 111. The reinforcing beam 14 is located between the two second beams 112 and includes a mounting beam 141 that extends in the first direction and two reinforcing beams 142 that extend in the second direction, and the two reinforcing beams 142 are respectively connected to both ends of the mounting beam 141 in the first direction, and each reinforcing beam 142 is connected to the adjacent first beam 111 in the first direction, and both ends of each reinforcing beam 142 in the second direction are respectively connected to the two second beams 112, and the first direction intersects with the second direction.

[0063] Among them, at least two batteries 20 are arranged side by side between the two second beams 112 along the second direction and supported on the bottom frame 11 and the reinforcing beam 14, and each battery 20 arranged between the two second beams 112 is connected to the two first beams 111 at both ends along the first direction, and the mounting beam 141 is used to connect with two adjacent batteries 20 arranged between the two second beams 112.

Regardless of whether the battery 20 is directly or indirectly mounted on the bottom frame 11, the weight of the battery 20 is mainly borne by the bottom frame 11, that is, the bottom frame 11 plays a major role in bearing the weight.

[0065] The two ends of each second beam 112 along the first direction are respectively connected to the two first beams 111, one end of each second beam 112 along the first direction is connected to one of the first beams 111, and the other end of each second beam 112 along the first direction is connected to the other first beam 111.

The above connection method between the first beam 111 and the second beam 112 can make the connection between the first beam 111 and the second beam 112 a rigid connection, which is conducive to better transmission of the force on the second beam 112 to the first beam 111.

[0066] The first direction and the second direction intersect, for example, the first direction is perpendicular to the second direction, the first direction is perpendicular to the up-down direction, and the second direction is perpendicular to the up-down direction. For example, the first direction can refer to the e1 direction in the figure, and the second direction can refer to the e2 direction in the figure. For example, one of the first direction and the second direction can extend in the lateral direction of the vehicle body 200, and the other of the first direction and the second direction can extend in the longitudinal direction of the vehicle body 200.

[0067] The two reinforcing beams 142 are respectively connected to both ends of the mounting beam 141 along the first direction, wherein one reinforcing beam 142 is connected to one end of the mounting beam 141 along the first direction, and the other reinforcing beam 142 is connected to the other end of the mounting beam 141 along the first direction.

[0068] The reinforcing cross beam 142 and the mounting beam 141 may be connected by welding to improve the connection rigidity between the reinforcing cross beam 142 and the mounting beam 141 , so that the overall structural strength of the reinforcing beam 14 is higher.

[0069] Optionally, the reinforcing crossbeam 142 and the mounting beam 141 may both be made of profiles, for example, the reinforcing crossbeam 142 and the mounting beam 141 may both be made of rectangular profiles, for example, the reinforcing crossbeam 142 and the mounting beam 141 may be made of rectangular steel or rectangular aluminum alloy.

[0070] Each reinforcing cross beam 142 is connected to an adjacent first beam 111 along a first direction. The reinforcing cross beam 142 and the first beam 111 may be connected by welding or by fasteners.

[0071] Both ends of each reinforcing beam 142 along the second direction are respectively connected to the two second beams 112, one end of each reinforcing beam 142 along the second direction is connected to one of the second beams 112, and the other end of each reinforcing beam 142 along the second direction is connected to the other second beam 112. The reinforcing beam 142 and the second beam 112 may be connected by welding.

[0072] In the above technical solution, by arranging a reinforcing beam 14 between the two second beams 112 of the bottom frame 11, the structural strength of the bottom frame 11 can be improved, and the reinforcing beam 14 can be used to support the battery 20 arranged between the two second beams 112, so as to increase the supporting area of ​​the battery 20 located between the two second beams 112, so as to improve the supporting strength, stability and reliability of the bottom frame 11 for the battery 20 between the two second beams 112, and the battery 20 located between the two second beams 112 is connected to the reinforcing beam 14, which can improve the stability and reliability of the installation of the battery 20, and can improve the overall structural strength and stability of the battery assembly 100; and by arranging the reinforcing beam 14 to include a mounting beam 141 and a reinforcing cross beam 142 connected to both ends of the mounting beam 141, the reinforcing beam 14 is formed into an I-beam, so that the overall structural strength of the reinforcing beam 14 is relatively high, which can better improve the structural strength of the battery supporting bracket 10, reduce the risk of damage to the battery supporting bracket 10, provide stable and reliable support for the battery 20, and the overall structural strength and stability of the battery assembly 100 are relatively high.

[0073] In some embodiments, the second beam 112 is connected to adjacent cells 20 .

[0074] For example, the second beam 112 and the adjacent battery 20 may be connected using fasteners.

[0075] In the above technical solution, connecting the second beam 112 to the adjacent battery 20 can further improve the stability and reliability of the installation of the battery 20, and can make the overall structural strength and stability of the battery assembly 100 higher.

[0076] In some embodiments, reference Figure 3-Figure 6 The battery supporting bracket 10 includes a first support beam 131 and a second support beam 132. The first support beam 131 is connected to the upper surface of the second beam 112 and extends along the first direction. The second support beam 132 is connected to the upper surface of the mounting beam 141 and extends along the first direction. A storage space for accommodating the battery 20 is defined between the first support beam 131 and the second support beam 132.

[0077] In the above technical solution, by setting the first support beam 131 and the second support beam 132, the structural strength of the battery supporting bracket 10 can be further improved, thereby improving the stability and reliability of the battery supporting bracket 10 in supporting the battery 20; and, the battery 20 is accommodated in the space defined by the first support beam 131 and the second support beam 132, and the installation of the battery 20 can be limited by the first support beam 131 and the second support beam 132, so as to facilitate the installation of the battery 20 and make the installation of the battery 20 more stable.

[0078] In some embodiments, the first support beam 131 and the second beam 112 are connected by welding or formed as one piece, and the second support beam 132 and the mounting beam 141 are detachably connected.

[0079] The second support beam 132 and the mounting beam 141 are detachably connected, and the second support beam 132 and the mounting beam 141 may be connected by fasteners.

[0080] In the above technical solution, by making the second support beam 132 and the mounting beam 141 detachably connected, the second support beam 132 can be formed into a detachable movable beam, which is convenient for the installation of the battery 20 and the second support beam 132, and also convenient for the disassembly and assembly of the battery 20 located between the first support beam 131 and the second support beam 132; while the second support beam 132 and the mounting beam 141 are detachably connected, the first support beam 131 and the second beam 112 are welded or integrally formed, so that the connection between the first support beam 131 and the second beam 112 has Higher stability and reliability can facilitate the disassembly and assembly of the battery 20 between the first support beam 131 and the second support beam 132, while making the overall structure more stable; in addition, the second support beam 132 is located between the two first support beams 131. Since the second support beam 132 is a movable beam, the amplitude at the second support beam 132 is larger than the amplitude at the first support beam 131. By setting an I-shaped reinforcement beam 14, it can be used to limit the amplitude at this location, thereby improving the structural strength of the battery support bracket 10 and reducing the risk of failure of the battery support bracket 10.

[0081] In some embodiments, reference Figure 6 and Figure 7 , the projection of the battery 20 located between the first support beam 131 and the second support beam 132 on the horizontal plane partially overlaps with the projection of the second support beam 132 on the horizontal plane.

[0082] In the above technical solution, the projection of the battery 20 located between the first support beam 131 and the second support beam 132 on the horizontal plane partially overlaps with the projection of the second support beam 132 on the horizontal plane, which can reduce the occupied space in the horizontal direction, make the structure of the battery assembly 100 more compact, reduce space waste, improve space utilization, and help to improve the energy density of the battery assembly 100.

[0083] In some embodiments, reference Figure 7 The battery 20 has a mounting portion 21, the mounting portion 21 is supported on the upper surface of the mounting beam 141 and the mounting portion 21 is detachably connected to the mounting beam 141, and the second support beam 132 is supported on the upper surface of the mounting portion 21 and the second support beam 132 is detachably connected to the mounting portion 21.

[0084] The battery 20 has a mounting portion 21 , which may be located at the bottom of the battery 20 to support the battery 20 .

[0085] The mounting portion 21 is detachably connected to the mounting beam 141, which may include the mounting portion 21 being connected to the mounting beam 141 via a fastener. The second support beam 132 is detachably connected to the mounting portion 21, which may include the second support beam 132 being connected to the mounting portion 21 via a fastener.

[0086] Optionally, when the mounting portion 21 is connected to the mounting beam 141 through fasteners and the second support beam 132 is connected to the mounting portion 21 through fasteners, the mounting beam 141 and the second support beam 132 can be connected to the mounting portion 21 through their respective corresponding fasteners, or the mounting beam 141 and the second support beam 132 can be connected to the mounting portion 21 through common fasteners, which can reduce the number of fasteners and the number of mounting holes.

[0087] In the above technical solution, the battery 20 is connected to the mounting beam 141 by setting the mounting portion 21, which facilitates the connection between the battery 20 and the mounting beam 141, so that the mounting portion 21 of the battery 20 is detachably connected to the mounting beam 141 and the second support beam 132 is located on the upper surface of the mounting portion 21 and is detachably connected to the mounting portion 21, so that the second support beam 132 is formed into a detachable movable beam, which facilitates the installation of the battery 20 and the second support beam 132, and also facilitates the disassembly and assembly of the battery 20 located between the first support beam 131 and the second support beam 132.

[0088] In some embodiments, reference Figure 1-Figure 4 The battery supporting bracket 10 also includes a connecting frame 12, which is used to connect to the vehicle body 200. The connecting frame 12 is connected to the upper surface of the first beam 111 and extends along the second direction. The end of the first support beam 131 along the first direction is connected to the connecting frame 12.

[0089] The connecting frame 12 is used to connect to the vehicle body 200, and the connecting frame 12 and the vehicle body 200 may be detachably connected, so that the battery support bracket 10 and the vehicle body 200 are detachably connected. For example, the connecting frame 12 and the vehicle body 200 may be detachably connected by a locking accessory.

[0090] The connecting frame 12 is connected to the upper surface of the first beam 111 . The connecting frame 12 and the first beam 111 may be connected by welding or by fasteners.

[0091] The end of the first support beam 131 along the first direction is connected to the connecting frame 12. The first support beam 131 and the connecting frame 12 can be connected by welding or by fasteners. The first support beam 131 and the connecting frame 12 adopt the above-mentioned connection method, so that the connection between the first support beam 131 and the connecting frame 12 can be a rigid connection, which is conducive to better transmission of the force on the first support beam 131 to the connecting frame 12.

[0092] In the above technical solution, by connecting the end of the first support beam 131 to the connecting frame 12, and the connecting frame 12 is connected to the vehicle body 200, the overall structural strength of the battery supporting bracket 10 can be improved, and the force transmission path on the battery supporting bracket 10 can be optimized. Not only can the bottom frame 11 transmit the force it receives to the connecting frame 12, but the forces received by the reinforcing beam 14 and the first support beam 131 can also be transmitted to the connecting frame 12. In this way, the force received by the entire battery 20 supporting bracket can be transmitted to the connecting frame 12 through multiple paths, so that the overall force received by the battery 20 supporting bracket is dispersed, thereby reducing the risk of damage to the battery supporting bracket 10.

[0093] In some embodiments, the second support beam 132 is detachably connected to the mounting beam 141 , and an end portion of the second support beam 132 along the first direction is spaced apart from the connecting frame 12 .

[0094] The second support beam 132 and the mounting beam 141 are detachably connected, and the second support beam 132 and the mounting beam 141 may be connected by fasteners.

[0095] In the above technical solution, by making the second support beam 132 and the mounting beam 141 detachably connected, the second support beam 132 can be formed into a detachable movable beam, which is convenient for the installation of the battery 20 and the second support beam 132, and also convenient for the disassembly and assembly of the battery 20 located between the first support beam 131 and the second support beam 132; and, a gap is provided between the end of the second support beam 132 along the first direction and the connecting frame 12, so that there is no connection relationship between the second support beam 132 and the connecting frame 12, and there is no connection point between the second support beam 132 and the connecting frame 12, so that the connection points of the second support beam 132 are relatively reduced, so that in the process of disassembling and assembling the second support beam 132, the disassembly and assembly efficiency of the second support beam 132 can be improved, and since there is a gap between the end of the second support beam 132 along the first direction and the connecting frame 12, the interference between the second support beam 132 and the connecting frame 12 during the disassembly and assembly process can also be reduced, which can make the disassembly and assembly of the second support beam 132 more convenient and smooth.

[0096] In some embodiments, reference Figure 3-Figure 5 The reinforcing beam 14 includes a first angle beam 143 . The first angle beam 143 is disposed at a first corner between the reinforcing cross beam 142 and the mounting beam 141 . The first angle beam 143 is connected to both the reinforcing cross beam 142 and the mounting beam 141 .

[0097] The first angle beam 143 may be a triangular beam, so that the first angle beam 143 better matches the shape of the first corner between the reinforcing cross beam 142 and the mounting beam 141 .

[0098] The first angle beam 143 and the reinforcing cross beam 142 may be connected by welding, and the first angle beam 143 and the mounting beam 141 may also be connected by welding.

[0099] In the above technical solution, by setting the first angle beam 143 at the corner between the reinforcing cross beam 142 of the reinforcing beam 14 and the mounting beam 141, not only the structural strength of the reinforcing beam 14 can be further improved, but also the stress concentration at the corner between the reinforcing cross beam 142 of the reinforcing beam 14 and the mounting beam 141 can be reduced. In this way, the overall structural strength of the battery supporting bracket 10 can be higher and the local stress concentration can be reduced.

[0100] In some embodiments, reference Figure 3-Figure 5 The reinforcing beam 14 includes a second angle beam 144 . The second angle beam 144 is disposed at a second corner between the reinforcing cross beam 142 and the second beam 112 . The second angle beam 144 is connected to both the reinforcing cross beam 142 and the second beam 112 .

[0101] The second angle beam 144 may be a triangular beam, so that the second angle beam 144 better matches the shape of the second corner between the reinforcing cross beam 142 and the second beam 112 .

[0102] The second angle beam 144 and the reinforcing cross beam 142 may be connected by welding, and the second angle beam 144 and the second beam 112 may also be connected by welding.

[0103] In the above technical solution, by arranging a second angle beam 144 at the corner between the reinforcing cross beam 142 of the reinforcing beam 14 and the second beam 112, not only the structural strength of the battery supporting bracket 10 can be further improved, but also the stress concentration at the corner between the reinforcing cross beam 142 of the reinforcing beam 14 and the second beam 112 can be reduced. In this way, the overall structural strength of the battery supporting bracket 10 can be higher and the local stress concentration can be reduced.

[0104] Second, refer to Figure 8 , an embodiment of the utility model provides a vehicle 1000, comprising: a battery assembly 100 according to the first aspect of the embodiment of the utility model.

[0105] In the above technical solution, by setting the above-mentioned battery assembly 100, the battery supporting bracket 10 in the battery assembly 100 for supporting the battery 20 has a higher structural strength, reducing the risk of damage to the battery supporting bracket 10, and providing stable and reliable support for the battery 20. The overall structural strength and stability of the battery assembly 100 are relatively high.

[0106] Refer to the following Figure 1-Figure 7 A battery assembly 100 according to some embodiments of the present invention is described.

[0107] In this embodiment, the battery assembly 100 includes a battery support bracket 10 and a battery 20, and the battery support bracket 10 is used to support the battery 20.

[0110] The reinforcing beam 14 also includes a first angle beam 143 and a second angle beam 144. The first angle beam 143 is arranged at a first corner between the reinforcing cross beam 142 and the mounting beam 141, and the first angle beam 143 is connected to both the reinforcing cross beam 142 and the mounting beam 141. The second angle beam 144 is arranged at a second corner between the reinforcing cross beam 142 and the second beam 112, and the second angle beam 144 is connected to both the reinforcing cross beam 142 and the second beam 112.

[0111] The second support beam 132 is mounted on the upper surface of the mounting beam 141 and extends along the second direction, and the second support beam 132 is located between the two first support beams 131. There are two third support beams 133, and the two third support beams 133 are opposite and spaced apart along the first direction, and the two third support beams 133 are both mounted on the upper surface of the side beam and each third support beam 133 extends along the second direction.

[0112] Among them, an accommodation space for accommodating the battery 20 is defined between the adjacent first support beams 131 and the second support beams 132, and an accommodation space for accommodating the battery 20 is also defined between the adjacent first support beams 131 and the third support beams 133. The upper bracket 15 is arranged on the top of the first support beam 131, the second support beam 132 and the third support beam 133, and the upper bracket 15 can be connected to the first support beam 131, the second support beam 132 and the third support beam 133.

[0113] The battery 20 can be mounted on the upper bracket 15, so that the entire battery support bracket 10 can carry the batteries 20 arranged in two layers. Optionally, the upper bracket 15 may include a plurality of sub-brackets 151 arranged at intervals along the second direction, the sub-brackets 151 may extend along the first direction, and each sub-bracket 151 may be connected to the first support beam 131, the second support beam 132, and the third support beam 133.

[0114] The battery 20 located between the first support beam 131 and the second support beam 132 can be supported by the mounting beam 141 , the second beam 112 and the first beam 111 ; the battery 20 located between the first support beam 131 and the third support beam 133 can be supported by the second beam 112 and the first beam 111 .

[0115] The battery 20 has a mounting portion 21, and the battery 20 is connected to the battery supporting bracket 10 through the mounting portion 21.
