[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0027] Reference below Figure 1-Figure 3 The battery replacement structure 100 according to the first embodiment of the utility model is described.

[0028] like Figure 1 and Figure 2 As shown, the battery exchange structure 100 according to the first aspect of the embodiment of the utility model includes: a support beam 10, a battery exchange frame 20 and a battery pack 30.

[0029] Specifically, the support beam 10 is suitable for being connected to the bottom of the vehicle body. The support beam 10 is arranged along a first direction (eg Figure 1The battery exchange frame 20 includes a plurality of support frames 21. For example, the support frames 21 may be two, three or four. The plurality of support frames 21 are connected to the support beam 10 in the second direction (for example Figure 1 On both sides of the battery pack 30 (the left and right direction shown in the figure), the first direction, the second direction and the up and down directions are perpendicular to each other, and at least one fixing portion is provided on the support frame 21 (not shown in the figure). For example, the fixing portions may be two, six, eight, twelve or sixteen, and the fixing portions on the multiple support frames 21 are arranged at intervals in the first and second directions. A quick-change frame 31 is provided on the battery pack 30, and a plurality of mating portions 311 are provided on the quick-change frame 31. The fixing portions correspond to the mating portions 311 one by one and are detachably connected.

[0030] After the vehicle is assembled, the support beam 10 is connected to the bottom of the vehicle body. When the battery pack 30 of the vehicle needs to be replaced, the connection between the multiple fixing parts and the matching parts 311 is released, and then the old battery pack 30 is removed. The new battery pack 30 is then moved to the bottom of the vehicle, and the matching part 311 on the quick-change frame 31 is aligned with the fixed part on the battery exchange frame 20, and then the matching part 311 is connected to the fixed part, thereby completing the battery exchange process of the vehicle.

[0031] Among them, it can be understood that the battery pack 30 is connected to the battery exchange frame 20 through the quick-change frame 31, and the operating space is large during the installation and disassembly process, which can reduce the difficulty of connecting the matching part 311 and the fixed part, and the quick-change frame 31 and the battery exchange frame 20 can be deformed within a certain range. When connecting multiple groups of fixed parts and matching parts 311, the requirements for the relative position accuracy of the quick-change frame 31 and the battery exchange frame 20 can be reduced. Thereby, the operating difficulty during the replacement of the battery pack 30 can be reduced and the battery replacement speed can be improved.

[0032] When the battery pack 30 is connected to the battery exchange frame 20 through the quick-change frame 31, the fixing parts on the multiple support frames 21 are arranged at intervals in the first direction and the second direction, and the fixed parts are distributed more evenly. The multiple groups of matching parts 311 and the fixing parts cooperate to limit the battery pack 30 at multiple positions, thereby improving the rigidity of the battery exchange structure 100 and further improving the stability of the battery exchange structure 100 on the vehicle.

[0033] According to the battery swap structure 100 of the first aspect embodiment of the utility model, by setting a quick-change frame 31 on the battery pack 30, the quick-change frame 31 is easier to connect and disassemble on the battery swap frame 20, thereby improving the replacement speed of the battery pack 30, and the connection points between the quick-change frame 31 and the battery swap frame 20 are more evenly distributed, which can improve the stability of the battery swap structure 100.

[0034] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the quick-change frame 31 includes a first frame 312 and a plurality of connecting beams 313. For example, the connecting beams 313 may be two, three or four. The first frame 312 includes four first side beams connected end to end. The connecting beams 313 extend along a first direction. The two ends of the connecting beams 313 are respectively connected between two first side beams opposite to each other in the first direction. The plurality of connecting beams 313 are arranged at intervals in the second direction. The matching parts 311 are arranged on the connecting beams 313 and the two first side beams opposite to each other in the second direction. Thus, the plurality of matching parts 311 can be arranged at intervals on the quick-change frame 31. In the process of product design, the parameters such as the size of the first frame 312, the number of connecting beams 313 or the position of the connecting beams 313 in the first frame 312 can be adjusted to meet more product design requirements.

[0036] When the first side beam and the connecting beam 313 are subjected to a force, the first middle beam 314 can provide support between adjacent first side beams and connecting beams 313, and between two adjacent connecting beams 313, thereby improving the rigidity and strength of the quick-change frame 31, and further improving the rigidity and stability of the battery-swap structure 100. During product design, the number of first middle beams 314 connected between adjacent first side beams and connecting beams 313, the number of first middle beams 314 connected between two adjacent connecting beams 313, or the size of the first middle beam 314 can be adjusted to meet more product design needs.

[0037] In some embodiments of the present invention, Figure 1-Figure 3 As shown, there are two connecting beams 313, and there are two supporting frames 21. The two supporting frames 21 are respectively connected to the two sides of the supporting beam 10 in the second direction. The supporting frame 21 includes a second frame 211. The second frame 211 includes four second side beams connected end to end. The fixing part is arranged on two second side beams arranged relatively in the second direction.

[0038] During assembly, the two second side beams of the support frame 21 that are relatively arranged in the second direction are respectively connected to the adjacent connecting beams 313 and the matching parts 311 on the first side beam through fixing parts, wherein, preferably, two fixing parts are provided on a single second side beam, and two matching parts 311 are provided on a single connecting beam 313 and the first side beam.

[0043] In addition, the space occupied by the battery pack 30 and the quick-change frame 31 in the up and down directions can be reduced, thereby facilitating the arrangement of the battery pack 30 under the vehicle.

[0044] In some embodiments of the utility model, the quick-change frame 31 is connected to the box body 32 by bolts. The bolt connection has high strength and is easy to operate. The connection strength between the quick-change frame 31 and the box body 32 can more easily meet the use requirements and reduce the production difficulty.

[0045] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, in the up-down direction, part of the support beam 10 extends into the first avoidance channel 34 , and part of the support frame 21 extends into the first avoidance channel 34 and the second avoidance channel 35 .

[0047] In some embodiments of the utility model, the support frame 21 is connected to the support beam 10 by bolts. The bolt connection has high strength and is easy to operate. The connection strength between the support frame 21 and the support beam 10 can more easily meet the use requirements and reduce the production difficulty.

[0048] In some embodiments of the present invention, a plurality of fixing parts are symmetrically arranged on both sides of the support beam 10 in the second direction. Thus, the force distribution of the battery pack 30 on the battery exchange frame 20 can be made more uniform, thereby further improving the stability of the battery exchange structure 100.
