Description

Technical Field

With the increasing penetration rate of electric-driven new energy in the passenger car and engineering machinery industries, the demand for timely energy replenishment is also gradually increasing. Different from the characteristics of the passenger car industry with large product volume and relatively uniform power, the engineering machinery industry develops products of different powers and types according to various needs, so the required energy replenishment power is also different. Therefore, the charging piles of new energy products in the engineering machinery industry need to take into account the charging needs of different powers.

[0003] Existing charging piles are all designed with a fixed single power, which cannot take into account the wide variety of new energy products required by the engineering machinery industry.

The second fixing member 16 and the third fixing member 17 are respectively connected to the box body 11. The second fixing member 16 is provided with two and symmetrically arranged on both sides of the power module 14. The distance between the two second fixing members 16 can be adjusted to position power modules 14 of different specifications. The two fixing members 16 are respectively against the power module 14, and the two second fixing members 16 can move in the horizontal direction (i.e., along the Y-axis direction) to adjust the distance between the two second fixing members 16. By adjusting the distance between the two second fixing members 16, power modules 14 of different specifications can be installed. Since the accommodating cavity is divided into a first cavity 101 and a second cavity 102 by the partition 12, the electrical module 13 and the power module 14 are separately arranged. In order to obtain a more compact charging pile structure, the adjustment mode of the second fixing member 16 is set to move along the Y direction to adjust the distance, which can reduce the height of the second cavity 102 in the Z direction, thereby reducing the thickness of the charging pile in the Z direction, and obtaining a compact charging pile. There are two third fixing members 17. The third fixing members 17 can fix and support power modules 14 of different specifications by changing different sizes. Each third fixing member 17 is arranged close to the air inlet 103, and the third fixing member 17 is detachably connected to the box body 11 to support the bottom of the power module 14. In this embodiment, the charging pile with replaceable power module is compatible with wall-mounted installation and column-mounted installation.

In the cavity 102, the first fixing member 15 has a first adjustable space to adapt to power modules 14 of different specifications and sizes. The distance between the two second fixing members 16 can be adjusted to position and fix power modules 14 of different specifications. The third fixing member 17 is detachably connected to the box to support the bottom of the power module 14. By replacing the third fixing members 17 of different sizes, power modules 14 of different specifications can be adapted to change the power of the charging pile. The cooperation of the first fixing member 15, the second fixing member 16 and the third fixing member 17 can make the disassembly and assembly of the power module 14 more convenient, thereby realizing the quick maintenance function.
