Detailed Embodiments

[0027] Next, reference is made to Figures 1-3 describe the tray 100 according to the first aspect embodiments of the present utility model.

[0028] As Figures 1-3 shown, the tray 100 according to the embodiment of the first aspect of the present utility model includes a tray body 1 and a plurality of partition beams 2. In the description of the present utility model, the meaning of "a plurality of" is two or more than two.

[0029] Specifically, the tray body 1 includes a bottom plate 11 and a plurality of side beams 12. The plurality of side beams 12 are connected end to end in sequence. The bottom plate 11 is disposed on one side of the plurality of side beams 12 in the first direction (for example, Figure 1 the up and down direction in Figure 1 ). The bottom plate 11 and the plurality of side beams 12 jointly define a receiving cavity 13. The plurality of partition beams 2 are spaced in the receiving cavity 13. The plurality of partition beams 2 divide the receiving cavity 13 into a power distribution cavity 131 and a plurality of battery cell cavities 132. At least two battery cell cavities 132 are arranged in the second direction (for example,

[0030] the front and back direction in Figure 1 ). The power distribution cavity 131 is disposed between at least two battery cell cavities 132. The second direction is perpendicular to the first direction.

[0030] For example, in the examples of Figure 1 and Figure 2 , the tray body 1 includes four side beams 12. The four side beams 12 are connected end to end. The bottom plate 11 is disposed on one side of the side beams 12 in the first direction. Thus, the receiving cavity 13 is defined by the bottom plate 11 and the four side beams 12. Three partition beams 2 are disposed in the receiving cavity 13. The three partition beams 2 divide the receiving cavity 13 into a power distribution cavity 131 and three battery cell cavities 132. A power distribution component 202 is suitable for being installed in the power distribution cavity 131, and a battery cell module 201 is suitable for being installed in the battery cell cavity 132. With such an arrangement, it is beneficial to improve the arrangement regularity of the battery cell module 201 and the power distribution component 202 in the receiving cavity 13, improve the space utilization rate of the receiving cavity 13, improve the assembly efficiency of the battery cell module 201 in the tray 100, and at the same time avoid the mutual influence between the power distribution component 202 in the power distribution cavity 131 and the battery cell module 201 in the adjacent battery cell cavity 132, and / or the battery cell modules 201 in the adjacent two battery cell cavities 132, thereby improving the use safety of the tray 100.

[0031] Two of the three battery cell cavities 132 are arranged in the second direction. A power distribution cavity 131 is spaced between the above two battery cell cavities 132. Even if two battery cell modules 201 are arranged on both sides of the power distribution component 202 in the second direction, so that the power distribution component 202 is protected by the partition beams 2 and the battery cell modules 201 on both sides, which is beneficial to reducing the failure risk of the power distribution component 202.

[0032] According to the tray 100 of the embodiment of the present utility model, the accommodation cavity 13 of the tray body 1 is divided into a power distribution cavity 131 and a plurality of battery cell cavities 132 by the partition beams 2, wherein the power distribution cavity 131 is arranged between at least two battery cell cavities 132, improving the arrangement regularity of the battery cell module 201 and the power distribution component 202 in the accommodation cavity 13, increasing the space utilization rate of the accommodation cavity 13. At the same time, the power distribution component 202 in the power distribution cavity 131 is protected by the partition beams 2 on both sides and the battery cell module 201 in the adjacent battery cell cavity 132, thereby reducing the failure risk of the power distribution component 202.

[0033] In addition, each battery cell module 201 includes a plurality of battery cells 2011, and the length of the battery cells 2011 is less than the length of the tray 100 in the second direction. When the length direction of the battery cells 2011 is arranged along the second direction, it is easy to cause waste of the accommodation cavity 13 of the tray 100, reducing the energy density of the battery pack 200 and unable to meet the voltage and power requirements of the battery pack 200. When the length direction of the battery cells 2011 is arranged along the third direction (for example, Figure 1 the left - right direction in [description]), at least two battery cell modules 201 are arranged along the third direction on the tray 100, and the space of the power distribution cavity 131 is insufficient in the third direction, making it difficult to install the power distribution component 202. Thus, the tray 100 of this embodiment improves the rationality of the arrangement of the battery cell module 201 and the power distribution component 202 in the tray 100, ensuring the energy density of the battery pack 200 and meeting the voltage and power requirements of the battery pack 200.

[0034] According to some embodiments of the present utility model, the plurality of partition beams 2 includes a plurality of first partition beams 21, the plurality of first partition beams 21 are spaced apart along the second direction, each first partition beam 21 extends along the third direction, and the adjacent two first partition beams 21 and the tray body 1 jointly define the power distribution cavity 131, and the third direction, the second direction and the first direction are orthogonal to each other. As Figures 1-3 shown, two first partition beams 21 are arranged in the tray body 1. One ends of the two first partition beams 21 are connected to the side beam 12, and the other ends of the two first partition beams 21 extend towards the center of the accommodation cavity 13 along the third direction, so as to jointly define the power distribution cavity 131 by the two first partition beams 21, the side beam 12 and the bottom plate 11. In the second direction, the two first partition beams 21 protect both sides of the power distribution component 202 in the power distribution cavity 131 and at the same time limit the power distribution component 202, improving the installation stability and use stability of the power distribution component 202 in the accommodation cavity 13.

[0035] Furthermore, as Figures 1-3As shown, a plurality of partition beams 2 include a second partition beam 22. The second partition beam 22 extends along a second direction. The second partition beam 22 is connected to the first partition beam 21. Two adjacent first partition beams 21, the tray body 1 and the second partition beam 22 jointly define a power distribution cavity 131. The second partition beam 22 is provided at one end of two first partition beams 21 away from the side beam 12. The second partition beam 22 and the opposite side beam 12 limit the power distribution component 202 in a third direction, further improving the installation stability and use stability of the power distribution component 202 in the accommodation cavity 13.

[0036] Both ends of the second partition beam 22 in the second direction are respectively connected to the corresponding side beams 12, thereby improving the structural integrity of the battery cell cavity 132 defined by the second partition beam 22 and the first partition beam 21 and / or the tray body 1, limiting the installation of the battery cell module 201 in the tray body 1, and improving the installation and use stability of the battery cell module 201 in the tray body 1.

[0037] According to some embodiments of the present invention, an avoidance notch 23 is formed at the end of each partition beam 2. The avoidance notch 23 is located on the side of the partition beam 2 away from the bottom plate 11. Thus, it is beneficial to pass through the connecting piece at the avoidance notch 23, avoid damaging the connecting piece, and improve the electrical safety of the connection between the battery cell module 201 and the power distribution component 202 in the tray 100. The avoidance notch 23 is at the end of the partition beam 2, which is beneficial to reduce the connection distance between the connecting piece and the power distribution component 202 and the battery cell module 201. At the same time, after installing the connecting piece at the avoidance notch 23, the flatness of the side of the partition beam 2 away from the bottom plate 11 is increased, avoiding interference between the connecting piece and other components.

[0038] Refer to Figure 3 According to the battery pack 200 of the second aspect embodiment of the present invention, it includes a tray 100, a plurality of battery cell modules 201 and a power distribution component 202. The tray 100 is the tray 100 according to the above first aspect embodiment of the present invention. The plurality of battery cell modules 201 are respectively arranged in a plurality of battery cell cavities 132 of the tray 100. The power distribution component 202 is arranged in the power distribution cavity 131 of the tray 100.

[0039] According to the battery pack 200 of the embodiment of the present invention, by adopting the above tray 100, the installation stability and arrangement regularity of the battery cell module 201 and the power distribution component 202 are increased, which is beneficial to reducing the energy density of the battery pack 200, meeting the voltage and power requirements of the battery pack 200, and extending the service life of the battery pack 200.

[0040] Furthermore, refer to Figure 3, a plurality of battery cell modules 201 include a first battery cell module 2012 and a plurality of second battery cell modules 2013. The first battery cell module 2012 and the plurality of second battery cell modules 2013 are arranged along a third direction, the plurality of second battery cell modules 2013 are arranged along a second direction, the power distribution assembly 202 is located between two adjacent second battery cell modules 2013, and the third direction is perpendicular to the second direction. The battery pack 200 includes one first battery cell module 2012 and two second battery cell modules 2013. The two second battery cell modules 2013 and the power distribution cavity 131 are provided on one side of the tray 100 in the third direction, and the second battery cell module 2013, the power distribution assembly 202, and the second battery cell module 2013 are arranged in sequence along the second direction, so as to protect the power distribution assembly 202 by the two second battery cell modules 2013 and reduce the risk of failure of the power distribution assembly 202. The first battery cell module 2012 is provided on the other side of the tray 100 in the third direction to make full use of the space inside the tray 100, increase the space utilization rate of the battery pack 200, and thus minimize the volume of the battery pack 200 while meeting the power usage requirements of the battery pack 200, so as to increase the applicability of the battery pack 200.

[0041] Furthermore, the battery pack 200 further includes a plurality of first connectors 203 and a plurality of second connectors 204. Both ends of each first connector 203 are respectively connected to the power distribution assembly 202 and the second battery cell module 2013, and each first connector 203 is located at the avoidance notch 23 of the first partition beam 21 of the tray 100. Both ends of each second connector 204 are respectively connected to the first battery cell module 2012 and the second battery cell module 2013, and each second connector 204 is located at the avoidance notch 23 of the second partition beam 22 of the tray 100. For example, as Figure 2 and Figure 3 shown, the battery pack 200 includes two first connectors 203 and two second connectors 204. The first connector 203 is arranged in the avoidance notch 23 at one end of the first partition beam 21 adjacent to the second partition beam 22, so as to connect the power distribution assembly 202 and the second battery cell module 2013 by the first connector 203 and complete the electrical connection between the power distribution assembly 202 and the second battery cell modules 2013 on both sides. The second connector 204 is arranged in the avoidance notch 23 at the end of the second partition beam 22 adjacent to the side beam 12, so as to connect the first battery cell module 2012 and the second battery cell module 2013 by the second connector 204 and complete the electrical connection between the first battery cell module 2012 and the second battery cell module 2013. Thus, the electrical connection between the power distribution assembly 202, the first battery cell module 2012, and the two second battery cell modules 2013 is completed, and thus the circuit connection inside the battery pack 200 is completed.

[0042] Among them, the number of the battery cells 2011 in the battery cell module 201 can be odd. Then, the battery cell module 201 further includes electrical connection structures such as long copper bars, so that the electrical connection positions of the battery cell module 201 are opposite to the first connecting member 203 and / or the second connecting member 204. If the number of the battery cells 2011 in the battery cell module 201 is even, it is beneficial to eliminate electrical connection structures such as long copper bars, reduce the space requirement of the tray 100, simplify the assembly of the battery module, improve the assembly efficiency of the battery module, enhance the electrical safety of the battery pack 200, and reduce the cost of the battery pack 200.

[0043] In addition, referring to Figures 1-3 , the battery pack 200 further includes a high-voltage connecting member 205 and a low-voltage connecting member 206. Both the high-voltage connecting member 205 and the low-voltage connecting member 206 pass through the side beam 12 of the tray 100 and are connected to the power distribution component 202. Both the high-voltage connecting member 205 and the low-voltage connecting member 206 are located on the same side of the power distribution component 202 in the third direction, and a plurality of first connecting members 203 are all located on the other side of the power distribution component 202 in the third direction. The high-voltage connecting member 205 and the low-voltage connecting member 206 are spaced apart and penetrate through the side beam 12 connected to the first partition beam 21, so that the high-voltage connecting member 205 and the low-voltage connecting member 206 connect one side of the power distribution component 202 in the third direction, and the first connecting member 203 connects the other side of the power distribution component 202 in the third direction. Thereby, the distance between the high-voltage connecting member 205 and the low-voltage connecting member 206 and the first connecting member 203 is increased, so as to avoid interference between the high-voltage connecting member 205 and the low-voltage connecting member 206 and the first connecting member 203, and improve the installation stability and use stability of the battery pack 200.

[0044] According to some embodiments of the present invention, referring to Figures 1-3 , the battery pack 200 further includes a fast-charging connecting member 207. The fast-charging connecting member 207 is connected to the power distribution component 202. In the third direction, the fast-charging connecting member 207 is opposite to the second battery cell module 2013, and an insulating member is provided between the fast-charging connecting member 207 and the second battery cell module 2013. Among them, the fast-charging connecting member 207 is a charging cable, an adapter (charging head), etc. required to achieve the fast-charging function, so as to ensure that the battery pack 200 can be charged at a speed higher than the normal charging speed.

[0045] With such a setting, the charging speed of the battery pack 200 is improved by using the fast-charging connecting member 207. The fast-charging connecting member 207 is arranged on the side of the tray 100 corresponding to the side of the second battery cell module 2013 adjacent to the side beam 12, so as to reduce the distance between the fast-charging connecting member 207 and the power distribution component 202 and improve the electrical connection efficiency of the battery pack 200. Insulation treatment is performed between the fast-charging connecting member 207 and the second battery cell module 2013 through the insulating member to avoid mutual influence between the fast-charging connecting member 207 and the second battery cell module 2013.

[0046] Further, the insulating member is insulating glue, and a glue filling cavity is formed between the second battery cell module 2013 and the side beam 12 of the tray 100, and the glue filling cavity is filled with insulating glue. Thus, there is a certain distance between the fast charging connector 207 and the power distribution component 202. Filling the insulating glue in the glue filling cavity between the second battery cell module 2013 and the side beam 12 of the tray 100 can achieve the insulation treatment between the fast charging connector 207 and the second battery cell module 2013, simplify the insulation operation, and increase the insulation between the fast charging connector 207 and the second battery cell module 2013.
