Detailed Description
The utility model is further described below with reference to the following figures and specific examples.
As shown in fig. 1, which is a schematic view of a usage state of the charging and discharging base for replacing the battery of the electric truck according to the present invention, the battery pack is lifted by the lifting system and falls on the charging and discharging base of the present invention, and a circuit interface of the battery pack is butted with the charging and discharging interface 5 on the base, so that the battery pack is discharged to the outside for the use of the electric truck, or the battery pack is charged in a charging station. Therefore, the charging and discharging base for replacing the electric power of the electric truck can be installed and fixed on the electric truck or installed in a charging station and used as an independent component.
The charging and discharging base structure for replacing the battery of the electric truck is further shown in fig. 2, 3 and 4, and comprises a base platform 1, wherein the size of the base platform is similar to or consistent with the size of the cross section of the rectangular frame of the battery pack.
A high guide block 2 and a low guide block 3 on the base platform 1. Compared with the prior art which only adopts one guide block, the utility model adopts the guide blocks with two heights, namely high and low. The height of the high guide block 2 is higher than that of the low guide block 3, and the width of the high guide block 2 is greater than that of the low guide block 3.
The high guide block 2 is installed on the outer side of the base platform 1, a first guide inclined plane 21 arranged inwards is arranged at the top of the high guide block 2, and guides the bottom outer frame of the battery pack frame, so that the battery pack firstly contacts with the high guide block 2 in the falling process to perform first butt joint guide.
The low guide block 3 is arranged on the inner side of the base platform 2, the top of the low guide block 3 is provided with a second guide inclined surface 31 which is arranged outwards and used for guiding the inner frame at the bottom of the battery pack frame, so that the battery pack is contacted with the low guide block 3 immediately in the falling process to perform second butt joint guide.
