Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

A battery shell comprises an upper shell 1 and a lower shell 2 which are connected together, wherein a base 3 is arranged on the bottom surface of the lower shell 2, an integrally formed structure is formed between the base 3 and the lower shell 2, a handle 4 is hinged to the upper end surface of the upper shell 1, a first groove 5 is formed in one side of the upper shell 1, a charging port 6 is formed in one side surface close to the handle 4 of the first groove 5, cavities 10 are formed in four corners of the base 3, one side surface close to the edge of the base 3 is obliquely arranged, rollers 15 are rotatably arranged in one side close to an inclined surface of the cavity 10, two grooves 11 communicated with the cavities 10 and corresponding to the rollers 15 are formed in four corners of the bottom surface of the base 3, a horizontally-arranged telescopic groove 12 is formed in one side far away from the inclined surface of the cavity 10, and a limiting plate 13 located below the rollers 15 is inserted in the telescopic groove 12, a spring 14 is fixedly connected between one end of the limiting plate 13 and the bottom surface of the telescopic groove 12, the other end of the limiting plate 13 extends to one side of the cavity 10 provided with an inclined surface, and a slot 16 corresponding to the limiting plate 15 is formed in the roller 15.

The middle part of the upper shell 1 is provided with a placing groove 8 corresponding to the handle 4, and the handle 4 is hinged in the placing groove 8.

And fins 7 are arranged on the upper end surface of the upper shell 1 at positions avoiding the placing grooves 8 and the first grooves 5.

Screw grooves 9 are formed in the four corners of the upper shell 1 and the four corners of the upper portion of the lower shell 2, and the upper shell 1 and the lower shell 2 are fixedly connected through screws.

In the specific implementation of the invention, as shown in fig. 4 and 5, the roller 15 is composed of a bracket and a wheel, a groove corresponding to the wheel is formed at the lower end of the bracket, two sides of the wheel are rotatably connected between two side walls of the groove through bearings, two sides of the upper part of the bracket are also rotatably connected between two side walls of the cavity 10 through bearings, after the bracket is rotated out of the cavity 10, a slot 16 is formed on one side surface close to the limiting plate 13, in the initial state, as shown in fig. 4, the roller 15 is accommodated in the cavity 10, and the limiting plate is positioned below the cavity 10 under the thrust of a spring and limits the roller 15 to naturally rotate out of the cavity 10;

as shown in fig. 5, when the roller is in use, the limit plate 13 is pushed into the telescopic slot 12, the limit plate 13 compresses the spring to move into the telescopic slot 12, when the limit plate is completely separated from the cavity 10, the roller 15 automatically rotates downwards out of the cavity 10, then when the limit plate 13 is released, under the thrust of the spring, the limit plate 13 extends out of the telescopic slot 12 and moves towards the roller 15, when the limit plate is contacted with the roller 15, the roller 15 is pushed to move together, when the bracket on the roller 15 is contacted with the inclined surface of the cavity 10, the roller 15 stops moving, and the end of the limit plate 13 is inserted into the slot on the bracket of the roller 15, thereby limiting the roller 15, so that the roller 15 can not rotate towards the direction opposite to the advancing direction due to the advancing resistance when moving, when the roller 15 is not used, the limit plate 13 is pushed into the telescopic slot 12, then the roller 15 rotates upwards and is stored in the cavity, when the limiting plate 13 is loosened, the limiting plate 13 blocks the roller 15.
