[0051] In the present embodiment, as shown in Figure 2 , the interface assembly 50 can further include a second interface 52 and a third interface 53.

[0053] In some embodiments, as shown in Figure 2 As shown, the battery box further includes a fixing assembly 30; the fixing assembly 30 is detachably connected to one side of the second box body 12.
[0054] In this embodiment, as shown in Figure 2 As shown, the battery box can further include a fixing assembly 30; the fixing assembly 30 can be detachably connected to one side of the second box body 12, so that when the battery box is installed on the vehicle, the fixing assembly 30 can cooperate with the locking device of the vehicle to fix the relative position of the battery box and the vehicle, preventing the vehicle and the battery box from being separated during the driving process of the vehicle.
[0055] In some embodiments, as shown in Figure 2 , Figure 3 , Figure 4 As shown, the fixing assembly 30 includes a first lock 31 and a second lock 32; the first lock 31 is detachably connected to the second box body 12; the second lock 32 is detachably connected to the second box body 12; the first lock 31 and the second lock 32 are spaced apart along the width direction of the second box body 12.
[0056] In this embodiment, as shown in Figure 2 , Figure 3 , Figure 4 As shown, the fixing assembly 30 can include a first lock 31 and a second lock 32; the first lock 31 can be detachably connected to the second box body 12; the second lock 32 can be detachably connected to the second box body 12; the first lock 31 and the second lock 32 can be spaced apart along the width direction of the second box body 12. Due to the inevitable jolting of the vehicle during driving, especially for commercial new energy vehicles with high center of gravity, the jolting in the width direction of the vehicle body is more intense. After the battery box is installed on the vehicle, the width direction of the battery box is parallel to the width direction of the vehicle body, and when the vehicle body jolts, this arrangement can keep the battery box and the vehicle body relatively fixed.
[0057] In some embodiments, as shown in Figure 2 , Figure 3 ,Figure 4 As shown in the figure, the first lock 31 can include two first rods 311 and a second rod 312. The first rod 311 can be detachably connected to the second box 12 at one end and extend away from the second box 12 at the other end. The two first rods 311 can be spaced apart along the length direction of the second box 12. The second rod 312 can be fixedly connected to one end of one of the first rods 311 away from the second box 12 at one end and fixedly connected to one end of the other first rod 311 away from the second box 12 at the other end. The second lock 32 can include two third rods 321 and a fourth rod 322. The third rod 321 can be detachably connected to the second box 12 at one end and extend away from the second box 12 at the other end. The two third rods 321 can be spaced apart along the width direction of the second box 12. The fourth rod 322 can be fixedly connected to one end of one of the third rods 321 away from the second box 12 at one end and fixedly connected to one end of the other third rod 321 away from the second box 12 at the other end.
[0058] In this embodiment, as shown in the figure, Figure 2 , Figure 3 , Figure 4 The first lock 31 can include two first rods 311 and a second rod 312. The first rod 311 can be detachably connected to the second box 12 at one end and extend away from the second box 12 at the other end. The two first rods 311 can be spaced apart along the length direction of the second box 12. The second rod 312 can be fixedly connected to one end of one of the first rods 311 away from the second box 12 at one end and fixedly connected to one end of the other first rod 311 away from the second box 12 at the other end. When the battery box is assembled with the vehicle, the first lock 31 is closer to the outside of the vehicle in the width direction than the second lock 32, and the fluctuation degree of the outside of the vehicle when jolted is greater than that of the inside of the vehicle when jolted. This arrangement can make the first lock 31 have a better effect in resisting jolt in the width direction of the vehicle and can effectively prevent the connection between the battery box and the vehicle from loosening.
[0059] The second lock buckle 32 comprises two third rods 321 and a fourth rod 322. One end of the third rod 321 is detachably connected to the second box body 12, and the other end extends away from the second box body 12. The two third rods 321 are spaced apart along the width direction of the second box body 12. One end of the fourth rod 322 is fixedly connected to one end of one of the third rods 321 away from the second box body 12, and the other end is fixedly connected to one end of the other third rod 321 away from the second box body 12. After the battery box is assembled with the vehicle, the second lock buckle 32 is closer to the inner side in the width direction of the vehicle than the first lock buckle 31, and the fluctuation degree of the outer side of the vehicle when jolted is greater than that of the inner side of the vehicle when jolted. In this way, the second lock buckle 32 has sufficient strength to resist jolting in the width direction of the vehicle, and at the same time, the second lock buckle 32 resists jolting in the length direction of the vehicle. The first lock buckle 31 and the second lock buckle 32 act simultaneously, which can further prevent the connection between the battery box and the vehicle from loosening.
[0060] In some embodiments, as shown in Figure 2 、 Figure 3 、 Figure 4 The fixing assembly 30 comprises a plug 33. One end of the plug 33 is detachably connected to the second box body 12, and the other end extends away from the second box body 12.
[0061] In the present embodiment, as shown in Figure 2 、 Figure 3 、 Figure 4 The fixing assembly 30 can comprise a plug 33. One end of the plug 33 is detachably connected to the second box body 12, and the other end extends away from the second box body 12. The cross-sectional area of the end of the plug 33 away from the second box body 12 can be smaller than that of the end of the plug 33 close to the second box body 12. When the battery box is assembled with the vehicle, the end of the plug 33 away from the second box body 12 can first abut against the plug hole of the vehicle and enter the plug hole of the vehicle that matches the plug 33. Even if there is a certain relative misalignment between the battery box and the plug hole of the vehicle, the plug 33 can be guided by the inclined outer circumferential surface to accurately complete the installation.
[0062] In some embodiments, as shown in Figure 2 、 Figure 3 、 Figure 4 The battery box comprises two fixing assemblies 30. The two fixing assemblies 30 are spaced apart along the length direction of the second box body 12.
[0063] In the present embodiment, as shown in 、 、 As shown, the battery box can include two fixing assemblies 30. The two fixing assemblies 30 can be arranged at intervals along the length direction of the second box body 12, can effectively resist the inclination of the vehicle in the length direction of the vehicle during driving, and ensure the stability of the connection between the battery box and the vehicle.
