Description

Charging device

[0001] The present invention relates to a charging device capable of improving the assembly of a power module mounted in a case in a charging device for charging an electric vehicle.

[0002] Generally, electric vehicles (EVs) have not been commercialized for a long time due to issues such as the heavy weight of the batteries mounted on the vehicle and the time required for charging, compared to gasoline or diesel cars. However, with the recent depletion of fossil fuels and environmental pollution, interest in EVs that utilize electric energy instead of fossil fuels has intensified, leading to active research and development in this area.

[0003] As a result, the adoption of electric vehicles (EVs) has been increasing recently. EVs are equipped with batteries that supply power for propulsion and store electricity within them. Therefore, to operate an EV continuously, the battery must be charged. Accordingly, infrastructure for EV charging is required, and to meet the growing demand for EVs, fixed, standing charging facilities are being installed in various locations.

[0004] Here, electrical stability and the maintenance of a long-term lifespan are key factors for establishing a stable charging infrastructure for electric vehicles. This is because charging facilities are primarily installed outdoors, such as in public buildings, park parking lots, highway rest areas, and apartment complexes.

[0005] Charging facilities for electric vehicles include separate charging facilities and integrated charging facilities. A separate charging facility includes a power cabinet in which a number of electronic components, including a power module, are mounted in a box-shaped case, and a dispenser that receives power from the power cabinet to perform charging of the electric vehicle. An integrated charging facility is formed integrally in which the aforementioned dispenser and power cabinet form a single main body shape to perform charging of the electric vehicle.

[0006] At this stage, securing space for installing electric vehicle charging facilities is required. To achieve this, structural means are needed to reduce the size of the case housing multiple electronic components. For example, one can consider a method to efficiently utilize the space occupied by electronic components by modifying the arrangement structure of the components mounted within the case. Furthermore, electric vehicle charging facilities vary in case size depending on their application and specifications, requiring an electronic component arrangement structure that corresponds to these variations.

[0007] In particular, for power modules that perform the role of converting supplied alternating current (AC) power into direct current (DC) power, which is the charging power for electric vehicles, measures are required to improve assembly compatibility in response to various case sizes.

[0008] The present invention relates to a charging device, and more specifically, aims to provide a charging device capable of improving the assembly of a power module mounted in a case.

[0009] In addition, the purpose is to provide a charging device that allows a power module to be easily mounted through a support member that forms an opening and a receiving space on one side of the case and guides the movement path of the power module.

[0010] In addition, the purpose is to provide a charging device that facilitates wiring connection inside the case.

[0054] A support member (130) can be coupled to the inner surface of a case (110) to form a receiving space (111) in which a power module (120) is mounted, and can serve to support the mounted power module (120). Additionally, a PCB (Printed Circuit Board) assembly (140) can be coupled to the support member (130) and positioned in front (z-axis direction) of the receiving space (111).

[0055] Additionally, the charging cable (150) can serve to transmit power supplied from the power module (120) to the outside.

Additionally, the flat portion (1411) of the coupling plate (141) can be coupled to the guide portion (1311) of the upper support (131) and the guide portion (1321) of the lower support (132) described above through FIG. 5.

[0073] And through this, the charging device (100) according to one embodiment of the present invention has the effect of efficiently securing a space in which a plurality of electronic components, including a printed circuit board, are mounted inside the case (110).

[0074] In addition, a charging device (100) according to one embodiment of the present invention may include a cable bracket (142) coupled to a flat portion (1411) to form a wiring space (1421). Wiring, such as cables or wires, can be efficiently organized inside the case (110) through the wiring space (1421) formed in the cable bracket (142). Furthermore, this facilitates maintenance of the charging device (100) of the present invention and has the effect of ensuring electrical stability.

[0075] Furthermore, in a charging device (100) according to one embodiment of the present invention, a plurality of cable brackets (142) may be arranged in an intersecting manner, perpendicular to each other, on the front surface of a flat portion (1411). Through this, a space for mounting a plurality of electronic components on the front surface of the flat portion (1411) can be efficiently secured, while simultaneously organizing the wiring more efficiently.

[0076] Additionally, in a charging device (100) according to one embodiment of the present invention, the area of ​​the flat portion (1411) of the coupling plate (141) may be formed to be wider than the area of ​​the support member (130) supporting the power module (120).
