[0029] Please continue to refer to Figure 2 , the connection unit further includes: a first support box 12, a second support box 13 and a third support box 14; the first crossbeam 1 includes: a first frame 11; the first support box 12, the second support box 13 and the third support box 14 are welded on the first frame 11 in sequence. Here, the support box can also be called a support seat. Here, the first support box 12 is arranged in the middle of the first frame 11, and the second support box 13 and the third support box 14 are arranged on one side of the first support box 12.

[0030] Please continue to refer to Figure 2 , the connection unit further includes: a fourth support box 22, a fifth support box 23 and a sixth support box 24; the second crossbeam 2 includes: a second frame 21; the second frame is welded with the fourth support box 22, the fifth support box 23 and the sixth support box 24 in sequence. Here, the fourth support box 22 is arranged in the middle of the second frame 21, and the fifth support box 23 and the sixth support box 24 are arranged on one side of the fourth support box 22.

[0031] Please continue to refer to Figure 2 The battery frame also includes: a fixedly connected plug support seat 3 and a socket support frame 4; the plug support seat 3 is welded on the first longitudinal beam 51, and the socket support frame 4 is welded on the side of the first longitudinal beam 51 facing the second longitudinal beam 52; the plug support seat 3 is used to provide a position for placing the plug of the micro-van battery pack placed in the battery exchange frame; the socket support frame 4 is used to support the plug support seat.

[0032] Specifically, the plug support seat 3 includes: a bottom plate 31, a first side plate 321 and a second side plate 322; the first side plate 321 and the second side plate 322 are symmetrically arranged on both sides of the bottom plate 31. The first side plate 321 and the second side plate 322 form the side plate 32. The socket support frame 4 includes: a first support frame 41, a second support frame 42 and a harness bracket 43; the first support frame 41 and the second support frame 32 are stacked and welded on the side of the first longitudinal beam 51 facing the second longitudinal beam 52; the harness bracket 43 is welded on the second support frame 42 for placing the harness of the micro-van battery pack.

[0033] Here, a plurality of positioning pin sleeves 20 are evenly arranged on the first cross beam 1 and the second cross beam 2. Specifically, the number of positioning pin sleeves 20 is 2, one positioning pin sleeve 20 is assembled in the first frame 11 of the first cross beam 1, and the other positioning pin sleeve 20 is assembled in the second frame 21 of the second cross beam 2. It should be noted that the number of positioning pin sleeves 20 can be increased according to actual needs.

[0034] Here, the positioning pin (not shown in the figure) set on the micro-van battery pack is accurately inserted into the positioning pin sleeve 20 to ensure accurate positioning between the micro-van battery pack and the battery swap frame. When swapping batteries, the connection between the positioning pin and the positioning pin sleeve 20 is released through the unlocking device of the battery swap station, and the battery frame can be quickly separated from the micro-van battery pack.

[0035] See also Figure 2 , multiple locking mechanisms 10 are evenly arranged on the first crossbeam 1 and the second crossbeam 2, and are spaced a preset distance from multiple positioning pin sleeves 20. Specifically, the locking mechanism 10 includes a support box and a protrusion, and multiple support boxes are evenly arranged on the first crossbeam 1 and the second crossbeam 2. Multiple protrusions are fixedly arranged in each support box, and the protrusions can be inserted into the grooves (i.e., locking mechanisms) provided on the micro-van battery pack. The number of locking mechanisms 10 can be 2, one locking mechanism 10 is arranged at one end of the first skeleton 11 away from the third support box 14, and the other locking mechanism 10 is arranged at one end of the second skeleton 21 away from the sixth support box 24. In addition, on the first crossbeam 1, the positioning pin sleeve 20 is arranged between the locking mechanism 10 and the first support box 12; on the second crossbeam 2, the positioning pin sleeve 20 is arranged between the locking mechanism 10 and the fourth support box 22. Here, the locking mechanism 10 matches the locking mechanism (not shown) provided on the micro-van battery pack. When replacing the battery, the locking mechanism 10 is precisely inserted into the locking mechanism to strengthen the connection between the battery frame and the micro-van battery pack. When replacing the battery, only the connection between the locking mechanism 10 and the locking mechanism needs to be unlocked to quickly release the connection between the battery frame and the micro-van battery pack, which is convenient for the battery replacement equipment to quickly complete the disassembly and replacement of the battery pack, and has the effect of speeding up the battery replacement. It should be noted that the number of locking mechanisms 10 can be increased according to actual needs.

[0036] Depend on Figure 2 It can be found that by making the structure arrangement on the first crossbeam 1 and the second crossbeam 2 symmetrical, the installation stability of the micro-faceted battery pack can be strengthened, and the same setting on both sides is also easier to disassemble when replacing the battery. In addition, in order to avoid the problem of excessive weight of the battery frame, increased production costs, and difficulty in handling, while ensuring the reliability of the support, the entire battery replacement frame adopts a pattern hollowing method to reduce weight. The hollow pattern can be triangular, circular, rectangular, etc.

[0037] Here, after the battery frame is fixed to the bottom of the electric vehicle's frame through a connecting unit, it will not be removed during the battery replacement process. When replacing the battery, the battery replacement equipment separates the micro-van battery pack from the battery frame by unlocking the connection between the locking mechanism and the locking mechanism, as well as the connection between the locating pin sleeve and the locating pin. The old micro-van battery pack is then taken out and the new micro-van battery pack is placed in the battery frame. Again, the locking mechanism 10 is accurately inserted into the locking mechanism, and the locating pin is accurately inserted into the locating pin sleeve 20 to fix the new micro-van battery pack to the bottom of the electric vehicle, and an electrical connection is established between the new micro-van battery pack and the electric vehicle to complete the battery replacement.

[0038] In view of the problem that the existing battery frame has low supporting strength, is prone to structural deformation during battery replacement, and is extremely difficult to disassemble, resulting in an extremely long disassembly time, the utility model proposes a battery frame for microvan battery replacement, which is fixed to the bottom of the electric vehicle through a connecting unit, and uses a battery replacement frame with extremely high bending resistance as the main frame of the battery frame to avoid structural deformation caused by external forces during driving or battery replacement; and the multiple locking mechanisms and positioning pin sleeves on the battery frame can accurately cooperate with the corresponding locking mechanisms and positioning pins on the microvan battery pack, and is easy to load and unload and firmly fixed. Especially in the scenario of microvan battery replacement, the connection between the battery frame and the microvan battery pack can be quickly released through the unlocking mechanism of the battery replacement equipment, which greatly improves the battery replacement speed, shortens the battery replacement time, and effectively improves the battery replacement efficiency.
