FIELD OF THE INVENTION

The present disclosure relates to a power supply device, and more particularly to a charging pile.

BACKGROUND OF THE INVENTION

With the development of the automobile industry, problems such as environmental pollution and energy shortage have gradually become an urgent issue to be addressed. Electric vehicles have the advantages of environmental protection and energy saving, so they have gradually been developed and promoted to replace traditional fuel vehicles. In recent years, the quantity of electric vehicles has increased rapidly, which has led to an increase in the demand for electric charging devices or charging piles. Therefore, charging piles have become a focus of research and development.

At present, a current charging pile for charging an electric vehicle is a single device, which includes a single housing and a circuit board assembly. The housing has an accommodating space, and a plurality of openings are disposed on the two sides of the housing, respectively. The circuit board assembly is mounted through one of the openings and disposed within the accommodating space of the housing. The housing further includes two water repellent mechanisms, which are mounted on the housing and corresponding in position to the corresponding openings of the housing, respectively, for achieving the purposes of waterproofing and ventilation. However, the current charging pile integrates all functional circuits into a circuit board assembly, and the circuit board assembly is installed inside the single housing. If some circuits or electronic components are damaged or malfunction and need to be repaired or replaced, the water repellent mechanisms on both sides of the housing must be disassembled and the circuit board assembly is removed from the housing through the opening. Therefore, the repairing and maintenance process is complicated and takes a long period of time, and the entire circuit board assembly may need to be replaced during maintenance, so that the maintenance cost is increased. In addition, the current charging pile is a single device that cannot be expanded, and the output power and specifications are immutable, so that only a specific level of output power can be provided. The current charging piles are unable to expand according to the practical requirements, which cause the limitation of application of the charging piles.

If another specific level of output power needs to be provided, the housing and the circuit board assembly of the charging pile must be redesigned. Consequently, the cost of molds, fixtures and manufacturing are increased, and the time for product design and production is also increased. Furthermore, since the current charging pile is a single device, it is difficult to disassemble and transport the charging pile, which may result in higher transportation costs.

On the other hand, the current water repellent mechanism of the charging pile includes a plurality of channels and baffles, and it has the disadvantages of complicated structure, high manufacturing costs and poor waterproof efficiency. Moreover, the water repellent mechanism is mounted on the housing and corresponding in position to the opening by means of screws locking, so that not only the time of assembling and producing is increased, but also the time of repairing is increased. Furthermore, additional locking portions and locking holes need to be employed to the corresponding positions of the housing and the water repellent mechanism. Accordingly, the structure of the housing is more complicated, and it is difficult to align and position the components in the assembling process. Moreover, the screw is easily damaged by rust or fatigue after being used for a long period of time, which causes the difficulty in subsequent disassembly operations.

In addition, when the charging pile is in operation, the circuit board assembly generates a large amount of heat energy due to the power conversion. Since the current charging pile lacks an effective heat dissipation mechanism, the heat dissipation efficiency is low. Consequently, the operation efficiency of the charging piles is affected.

Therefore, there is a need of providing an improved charging pile to obviate the drawbacks of the prior art.

SUMMARY OF THE INVENTION

It is an object of the present disclosure to provide a charging pile to address the issues of complex structure, difficult assembly, high production and maintenance costs, longer maintenance operation time, poor efficiency of waterproofing and heat dissipation, and failing to be expanded according to the practical requirements to reach a higher output power, which are encountered by the prior art.

It is another object of the present disclosure to provide a charging pile. The charging pile includes at least one modular power module and a modular control module so that the advantages of simplifying the structure, reducing the cost of production and maintenance, reducing the time of production, assembly and maintenance, and improving the heat dissipation efficiency are achieved. Moreover, the charging pile can be expanded according to requirements of output power, so that additional time and costs of redesigning are avoided and the scope of application is expanded. In addition, the charging pile further includes a waterproof device which is compressed and disposed between the control module and the power module and is surrounding around the periphery of the openings of the control module and the power module, so that the advantages of improving the waterproof efficiency, simplifying the structure and reducing the time of production, assembly and maintenance are achieved.

In accordance with an aspect of the present disclosure, a charging pile is provided. The charging pile includes a supporting device, a control module and at least one power module. The control module is fixed on the supporting device and includes a first housing, a control unit and at least one waterproof device. The first housing has at least one first opening. The control unit is disposed within the first housing. The at least one waterproof device is disposed on the periphery of the at least one first opening. The at least one power module is fixed on the supporting device and is disposed on the top of the control module. The power module includes a second housing and a power supply unit. The second housing has at least one second opening, and the power supply unit is disposed within the second housing. The at least one second opening of the second housing is in communication with the at least one first opening of the first housing. The control unit is electrically coupled with the power supply unit of each power module. The at least one waterproof device is disposed between the first housing and the second housing and surrounding around the periphery of the at least one first opening and the periphery of the at least one second opening.
