【Detailed ways】

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Referring to Fig. 1, the utility model discloses a rechargeable suitcase, which includes a suitcase body 10 and a suitcase cover 20 rotatably connected to the side of the suitcase body 10, generally, in The suitcase casing 10 is equipped with handles, locks, pull bars and the like. In this embodiment, as shown in Fig. 2 to Fig. 4, there is an inner box 101 in the suitcase body 10, and the inner box 101 is provided with a placement box 102 made of EVA material soft partition, the placement box 102 There are multiple flexible lining partitions 103 inside, which divide the storage box 102 into multiple separate cavities, which are convenient for placing various digital products. Of course, when not needed, the soft lining partitions 103 can be directly placed take out.

Further, a battery 104 is fixed on one side of the inner box 101, and a switching power supply 105 is fixed on the adjacent side of the inner box 101, and the battery 104 is connected to the switching power supply 105 through wires; the inner box 101 A heat dissipation fan 106 is also installed on the top, and the heat dissipation fan 106 is electrically connected to the switching power supply 105 through wires. One end of the fixed side of the battery 104 extends outward to form an extension edge 1040, and the above-mentioned heat dissipation fan 106 is fixed on the extended side. On the side 1040, there are through holes arranged in an array on the extended side 1040. The cooling fan 106 is installed behind the through holes. 104 operating temperature.
