Description

Technical Field

[0001] The utility model relates to the technical field of new energy charging piles, and in particular to a charging pile casing assembly. Background Art

[0002] A charging pile is a device that provides power replenishment for electric vehicles. Its function is similar to that of a gas pump in a gas station. It can be fixed on the ground or on the wall and installed in public buildings (charging stations, shopping malls, public parking lots, etc.) and residential parking lots. It can charge various types of electric vehicles according to the adjusted voltage and current.

[0003] In the prior art, charging piles are usually assembled by directly installing components into the pile body using bolts or other methods. The charging module in the charging pile needs to be connected to the line and maintained regularly, so it must be plugged and unplugged from the line plug many times, causing the interface to loosen or be damaged. The charging module is a high-precision component, and accurate adjustment of voltage and current is required to ensure stable voltage and current for charging the car. Loose and damaged interfaces will inevitably affect the charging accuracy of the charging module, thereby increasing maintenance costs.

[0004] The performance of a charging pile's heat dissipation device directly affects charging efficiency and equipment life. The heat dissipation requirements of a charging pile are closely related to its charging power, and are also affected by factors such as the operating environment temperature and the thermal conductivity of the charging pile material. In existing technologies, since some charging piles need to operate outdoors for long periods of time, and since parked cars bring dust into the surrounding environment, the charging pile's heat dissipation system is easily clogged or accumulates due to large amounts of dust. Furthermore, if there is no filter installed in the charging pile, dust will be introduced into the exhaust due to heat dissipation, thus affecting the heat dissipation effect. Utility Model Content

[0017] Furthermore, since the module bracket includes a mounting base, columns are vertically installed on the four corners of the mounting base, and the columns and the mounting base are fixedly connected to the outer shell of the charging pile and the electrical fixing plate by bolts. A plurality of module support plates supporting the longitudinal sliding placement of the charging module are vertically and evenly installed between the two columns on the longitudinal direction of the mounting base.

[0018] Since the baffle corresponds to the air inlet door and the module fixing plate corresponds to the air outlet door, when the air enters, the baffle can effectively block the airflow, thereby dispersing the airflow so that the airflow can pass through other positions, taking away as much heat as possible and improving the heat dissipation effect.

[0019] Furthermore, since the fixing structure is a module rib on the charging module, the module rib is fixed to the column on one side by bolts, and a module pressure plate is installed on the column on the other side to press the end face of the charging module; the module baffle can further support the end face of the charging module located at the installation inlet and outlet, thereby improving the firmness of the installation of the charging module.

[0022] Furthermore, since the exhaust device includes a fan mounting bracket fixedly mounted on the shutter of the air outlet door, a cooling fan is fixedly mounted on the fan mounting bracket to blow the air in the charging shell out of the air outlet door; the structure is simple, the installation is convenient, and the practicality is improved.

[0023] Furthermore, since the module support plate is an L-shaped structure, comprising a mounting plate portion and a support plate portion, the mounting plate portion is fixed to the column by bolts, and the column is provided with a positioning groove for embedding the support plate portion; the support plate portion can ensure stable and reliable support, the positioning groove can facilitate installation and fixation, and effectively limit the position during installation, thereby improving installation efficiency.
