Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] As described in the background section, existing T-beams have mounting holes at both ends. Steel sleeves are pressed into these holes with an interference fit, and then bolts are used to fasten the module end plate to the steel sleeves. However, conventional T-beams are made of extruded aluminum alloy profiles, which have low tensile strength. Furthermore, during bolt tightening, the steel sleeves are prone to stripping, which not only affects the reliability of the connection between the T-beam and the module end plate but also reduces the overall installation stability of the battery cell.

[0029] Based on this, please refer to Figures 1-6 This utility model provides a cell support beam 100, a battery module 110, a battery pack 1100, and a new energy vehicle 1000, which can effectively improve the aforementioned technical problems. Specifically, the beam has high tensile strength and can improve the connection reliability between the support beam and the module end plate, thereby enhancing the overall installation stability of the cell. The cell support beam 100, battery module 110, battery pack 1100, and new energy vehicle 1000 will be described in detail below.

[0030] Please refer to Figure 1 , Figure 1 This is a structural schematic diagram of the new energy vehicle 1000 provided in this embodiment, combined with... Figure 1 The new energy vehicle 1000 includes a battery pack 1100 and a vehicle body 1200. The battery pack 1100 is installed on the vehicle body 1200 to provide electrical energy to the vehicle body 1200 so as to realize the various functions of the vehicle body 1200.

[0031] Specifically, the battery pack 1100 includes a battery casing and a battery module 110, with the battery module 110 disposed within the battery casing. It should be noted that, as will be readily apparent to those skilled in the art, the battery pack 1100 may also include other structures such as a battery management system and a liquid cooling system; these will not be elaborated upon in this embodiment.

[0032] Please refer to Figure 2 , Figure 2 This is a structural schematic diagram of the battery module 110 provided in this embodiment, combined with... Figure 2 The battery module 110 includes a cell support beam 100, a first module end plate 200, a second module end plate 300, and multiple battery packs 400. The multiple battery packs 400 are arranged in sequence at intervals. A cell support beam 100 is provided between two adjacent battery packs 400. The first module end plate 200 and the second module end plate 300 are respectively connected and fixed to the two ends of the cell support beam 100, so that the multiple battery packs 400 are stably installed as a whole.

[0033] It should be noted that each battery pack 400 includes multiple cells, which are arranged sequentially.

[0034] Please refer to Figure 3 , Figure 3 This is a first-view structural schematic diagram of the cell support beam 100 provided in the embodiment, combined with... Figure 2 and Figure 3 The battery cell support beam 100 includes a roll-formed steel beam 10, a first threaded sleeve 30, and a second threaded sleeve 40. The roll-formed steel beam 10 has a first mounting space 21 and a second mounting space 22 at its two ends, respectively. The first threaded sleeve 30 is disposed in the first mounting space 21, and the second threaded sleeve 40 is disposed in the second mounting space 22. Both the first threaded sleeve 30 and the second threaded sleeve 40 are welded to the roll-formed steel beam 10.

[0035] As is easily understood, the roll-formed steel beam 10 is a steel beam body manufactured by a roll forming process. Compared with beam bodies made of aluminum alloy extruded profiles in the prior art, it can be directly welded to the first threaded sleeve 30 and the second threaded sleeve 40, thereby improving the tensile strength of the beam body. Furthermore, the first module end plate 200 can be directly connected to the first threaded sleeve 30, and the second module end plate 300 can be directly connected to the second threaded sleeve 40 using bolts, eliminating the possibility of stripping the threads when tightening the bolts. This improves the connection reliability between the support beam and the module end plate, enhancing the overall installation stability of the battery cell. In addition, by providing the first installation space 21 and the second installation space 22, the installation and welding of the first threaded sleeve 30 and the second threaded sleeve 40 can be facilitated, thereby improving assembly efficiency.

[0036] Further, please refer to Figures 4-6 , Figure 4 for Figure 3 A magnified view of a portion of point A in the middle. Figure 5 This is a second-view structural schematic diagram of the cell support beam 100 provided in this embodiment. Figure 6 for Figure 5 A magnified view of a section at point B. (Combined with...) Figures 3-6 The roll-formed steel beam 10 includes a first side plate 11, a second side plate 12, and a base plate 15. The first side plate 11 and the second side plate 12 are spaced apart from the base plate 15, and an installation space 20 is formed between the first side plate 11, the second side plate 12, and the base plate 15. The installation space 20 includes a first installation space 21 and a second installation space 22. A first threaded sleeve 30 is welded to one end of both the first side plate 11 and the second side plate 12, and a second threaded sleeve 40 is welded to the other ends of both the first side plate 11 and the second side plate 12.

[0037] By simultaneously welding the first threaded sleeve 30 and the second threaded sleeve 40 to the first side plate 11 and the second side plate 12, the connection stability of the threaded sleeves can be improved, thereby enhancing the overall tensile strength of the battery cell support beam 100 and correspondingly increasing its axial resistance to battery cell expansion.

[0038] Specifically, the first side plate 11 includes a first vertical segment 111, a first horizontal segment 112, a second vertical segment 113, and a second horizontal segment 114 connected in sequence. The first horizontal segment 112 extends away from the second side plate 12, the second horizontal segment 114 extends towards the second side plate 12, and the second vertical segment 113 is located on the side of the first horizontal segment 112 away from the first vertical segment 111.

[0039] The second side plate 12 includes a third vertical segment 121, a third horizontal segment 122, a fourth vertical segment 123, and a fourth horizontal segment 124 connected in sequence. The third horizontal segment 122 extends away from the first side plate 11, the fourth horizontal segment 124 extends towards the first side plate 11, and the fourth vertical segment 123 is located on the side of the third horizontal segment 122 away from the third vertical segment 121.

[0040] The first threaded sleeve 30 is simultaneously welded to one end of the first vertical section 111, one end of the second horizontal section 114, one end of the third vertical section 121, and one end of the fourth horizontal section 124. The second threaded sleeve 40 is simultaneously welded to the other end of the first vertical section 111, the other end of the second horizontal section 114, the other end of the third vertical section 121, and the other end of the fourth horizontal section 124.

[0041] like Figure 4 and Figure 6 As shown, it can be understood that the first threaded sleeve 30 and the roll-formed steel beam 10 have four welding points, and similarly, the second threaded sleeve 40 and the roll-formed steel beam 10 also have four welding points. That is, the circumferential parts of the two threaded sleeves can be welded to four parts of the roll-formed steel beam 10, thereby further improving the welding strength of the first threaded sleeve 30 and the second threaded sleeve 40, which in turn further improves the overall tensile strength of the battery cell support beam 100 and the connection reliability with the module end plate, and enhances the overall installation stability of the battery cell.

[0042] Please continue to combine Figure 4 and Figure 6 The first side plate 11 further includes a fifth horizontal segment 115, which connects to the side of the first vertical segment 111 away from the first horizontal segment 112, and extends in a direction away from the second side plate 12. The second side plate 12 further includes a sixth horizontal segment 125, which connects to the side of the third vertical segment 121 away from the third horizontal segment 122, and extends in a direction away from the first side plate 11. By providing the fifth horizontal segment 115 and the sixth horizontal segment 125, the axial expansion resistance of the cell support beam 100 can be further improved.

[0043] It should be noted that, from Figure 4 or Figure 6 As can be seen, the sequential connection of the fifth horizontal segment 115, the first vertical segment 111, the first horizontal segment 112, the second vertical segment 113, and the second horizontal segment 114 forms a structure resembling the shape of a "2" or a "5". Similarly, the sequential connection of the sixth horizontal segment 125, the third vertical segment 121, the third horizontal segment 122, the fourth vertical segment 123, and the fourth horizontal segment 124 forms a structure resembling the shape of a "2" or a "5". The first threaded sleeve 30 or the second threaded sleeve 40 is positioned between the "2" and "5" shaped structures, resulting in a symmetrical distribution and uniform stress distribution. This further improves the overall tensile strength of the cell support beam 100, the reliability of its connection with the module end plate, and ultimately enhances the overall installation stability of the cell.

[0044] Please continue to combine Figures 3-6 The roll-formed steel beam 10 also includes a third side plate 13 and a fourth side plate 14. The first side plate 11, the third side plate 13, and the bottom plate 15 are connected in sequence, and the second side plate 12, the fourth side plate 14, and the bottom plate 15 are connected in sequence. The third side plate 13 has a first heating groove 131 on the side away from the fourth side plate 14, and the fourth side plate 14 has a second heating groove 141 on the side away from the third side plate 13.

[0045] As is easily understood, the battery module 110 also includes a first heating wire and a second heating wire (not shown in the figure). The first heating wire is disposed in the first heating groove 131, and the second heating wire is disposed in the second heating groove 141. That is to say, the first heating wire and the second heating wire can heat the entire cell support beam 100, thereby transferring heat to the battery packs 400 on both sides. This facilitates the heating of the battery packs 400 located on both sides of the cell support beam 100, ensuring that the battery module 110 operates at a suitable temperature.

[0046] It should be noted that in this embodiment, the first heating groove 131 and the second heating groove 141 are arranged at intervals, that is, the two heating grooves are not on the same horizontal line, which can heat different parts of the battery cell support beam 100, thereby improving the heating uniformity of the battery cell support beam 100 and thus improving the heating effect on the battery cell.

[0047] To further improve the overall structural strength of the cell support beam 100, the bottom wall of the first heating groove 131 is connected to the fourth side plate 14, and the bottom wall of the second heating groove 141 is connected to the third side plate 13.

[0048] In addition, to facilitate the installation or removal of the first and second heating wires, in this embodiment, the third side plate 13 is provided with a first assembly groove 132 and a second assembly groove 133 at both ends, and the two ends of the first heating groove 131 are respectively connected to the first assembly groove 132 and the second assembly groove 133. The fourth side plate 14 is provided with a third assembly groove 142 and a fourth assembly groove 143 at both ends, and the two ends of the second heating groove 141 are respectively connected to the third assembly groove 142 and the fourth assembly groove 143. The dimensions of the first assembly groove 132 and the second assembly groove 133 are larger than the dimension of the first heating groove 131, and the dimensions of the third assembly groove 142 and the fourth assembly groove 143 are larger than the dimension of the second heating groove 141.

[0049] In summary, embodiments of this utility model provide a cell support beam 100, a battery module 110, a battery pack 1100, and a new energy vehicle 1000. The cell support beam 100 includes a roll-formed steel beam 10, a first threaded sleeve 30, and a second threaded sleeve 40. The roll-formed steel beam 10 has a first mounting space 21 and a second mounting space 22 at both ends. The first threaded sleeve 30 is disposed in the first mounting space 21, and the second threaded sleeve 40 is disposed in the second mounting space 22. Both the first threaded sleeve 30 and the second threaded sleeve 40 are welded to the roll-formed steel beam 10. It is easily understood that the roll-formed steel beam 10 is a steel beam body manufactured by a roll forming process. Compared to beam bodies made of aluminum alloy extruded profiles in the prior art, it can be directly welded to the first threaded sleeve 30 and the second threaded sleeve 40, thereby improving the tensile strength of the beam body. Furthermore, the first module end plate 200 can be directly connected to the first threaded sleeve 30 and the second module end plate 300 can be directly connected to the second threaded sleeve 40 by bolts. There will be no stripping of the sleeve when tightening the bolts, thereby improving the connection reliability between the support beam and the module end plate and enhancing the overall installation stability of the battery cell.
