Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] See also Figure 1-Figure 3As shown, the portable charging tail box includes:

[0026] A storage box 1, a box cover 2 is rotatably mounted on the top of the storage box 1;

[0027] The solar charging structure is arranged on the top of the box cover 2. The solar charging structure includes four stacked track groups. Each track group includes two sliding tracks 3. A solar panel 4 is slidably installed between the two sliding tracks 3. The outlets of each track group are staggered. Two adjacent sliding tracks 3 are fixedly connected by welding.

[0028] The mounting structure is arranged at the bottom of the storage box 1 and is used for fixing the storage box 1 to the electric vehicle.

[0029] Depend on Figure 1-Figure 3 It can be seen that the power connection point of the solar panel 4 and the power connection point inside the storage box 1 are connected to each other through an insulating spring sheet;

[0030] The mounting structure includes a support plate 5 fixedly mounted on the bottom of the storage box 1, and two rotation grooves 6 are provided on both sides of the support plate 5;

[0031] An extension plate 7 is rotatably mounted inside each rotation slot 6, a sliding slot 8 is provided inside each extension plate 7, and a limit block 9 is slidably mounted inside each sliding slot 8;
