Description

Technical Field

[0001] This utility model relates to the field of charging piles, and more specifically, to a wall-mounted DC charging pile. Background Technology

[0002] With the increasing popularity of electric vehicles, the demand for DC charging stations is growing. Wall-mounted DC charging stations are widely used in parking lots, garages, and other locations due to their space-saving design and flexible installation. However, the limited installation space for wall-mounted DC charging stations means they are generally small in size. As the power of wall-mounted DC charging stations increases while their size decreases, electromagnetic interference between the power module and control module becomes more likely, and the large amount of heat generated by the power module can easily damage the control components of the control module. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a wall-mounted DC charging pile that not only has a compact structure but also has less electromagnetic interference and good heat dissipation performance, in view of the above-mentioned defects of the prior art.

[0006] In the wall-mounted DC charging pile of this utility model, the fan assembly includes a first fan unit and a second fan unit; The first fan unit and the second fan unit are positioned adjacent to the heat sink of the charging module.

[0007] In the wall-mounted DC charging pile of this utility model, the first fan unit and the second fan unit each include a plurality of fans arranged sequentially and at intervals along the first side of the charging module.

[0008] In the wall-mounted DC charging pile of this utility model, a display component is installed in the center of the panel; the control module is installed on the first side of the substrate, directly opposite the display component, and is electrically connected to the display component.

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0014] Figure 1 This is a three-dimensional structural diagram of a preferred embodiment of the wall-mounted DC charging pile of this utility model. Figure 2 This is an exploded structural diagram of a preferred embodiment of the wall-mounted DC charging pile of this utility model. Figure 3 This is a cross-sectional view of the internal cavity structure of a preferred embodiment of the wall-mounted DC charging pile of this utility model. Figure 4 This is a schematic diagram of the heat dissipation duct of a preferred embodiment of the wall-mounted DC charging pile of this utility model.

[0015] like Figure 1-4 As shown, the wall-mounted DC charging pile includes a housing 10, a panel 20, a back plate 40, a control module 60, and a charging module 30. The first side of the housing 10 and the panel 20 form a control module cavity 100, and the second side of the housing 10 and the back plate 40 form a charging module cavity 90. The control module 60 is installed in the control module cavity 100, and the charging module 30 is installed in the charging module cavity 90. The first side and the second side of the housing 10 are arranged opposite to each other, and the first side and the second side of the housing 10 are different sides.

[0016] In this invention, since the charging module and the control module are located in different cavities, no electromagnetic inductance is generated. Moreover, the heat generated by the charging module is confined within the charging module cavity, which has a smaller impact on the control module and therefore is less likely to damage the device.

[0017] In a further preferred embodiment of the present invention, the housing 10 includes a substrate 11, a first peripheral wall 12 extending perpendicularly to the substrate 11 along the periphery of a first side surface 111 of the substrate 11, and a second peripheral wall 13 extending perpendicularly to the substrate 11 along the periphery of a second side surface 112 of the substrate 11; the first side surface 111 of the substrate 11 faces the panel 20, and the second side surface 112 of the substrate 11 faces the back plate 40; the first side surface 111 of the substrate 11, the first peripheral wall 12, and the panel 20 form the control module cavity 100; the second side surface 112 of the substrate 11, the second peripheral wall 13, and the back plate 40 form the charging module cavity 90.

[0018] A fan assembly is mounted on the first side of the charging module 30; an air inlet 70 is mounted on the first side of the second peripheral wall 13 near the fan assembly; the air inlet 70 faces the fan assembly; an air outlet 70 is mounted on the second side of the second peripheral wall 13 away from the fan assembly; the first side and the second side of the second peripheral wall 13 are parallel to each other. The fan assembly includes a first fan unit 31 and a second fan unit 32; the first fan unit 31 and the second fan unit 32 are disposed adjacent to the heat sink of the charging module 30. The first fan unit 31 and the second fan unit 32 each include a plurality of fans arranged sequentially and at intervals along the first side of the charging module 30. Figure 4 As shown, the air inlet 70 and the air outlet can form a vertical heat dissipation channel that runs through the charging module cavity 90 but is isolated from the control module cavity 100. This not only improves the heat dissipation efficiency of the charging module but also prevents external dust from affecting the control module.

[0019] In a further preferred embodiment of the present invention, a display component 21 is mounted in the center of the panel 20; the control module is mounted on the first side 111 of the substrate 11, directly opposite the display component 21, and is electrically connected to the display component 21.

[0020] In a further preferred embodiment of this utility model, the housing 10, the panel 20, and the back plate 40 are all rectangular, and the control module cavity 100 and the charging module cavity 90 are rectangular cavities. The first fan unit 31 and the second fan unit 32 are disposed on the long side of the rectangular housing.

[0021] In a further preferred embodiment of the present invention, the device further includes a mounting plate 50, expansion screws, and fixing screws; the mounting plate 50 is provided with mounting holes; the box 10 is fixed to the wall by the expansion screws through the mounting holes on the mounting plate 50, and the two sides of the panel 20 are fixed to the two sides of the box 10 by screws.

[0022] In a further preferred embodiment of the present invention, a charging gun 81 and a charging gun bracket 80 are further included; a charging gun interface is provided at the bottom of the housing 10, the charging gun wire of the charging gun 81 is connected to the charging gun interface, and the charging gun bracket 80 is installed on the wall adjacent to the mounting plate 50.

[0023] The casing 10, panel 20, and back panel 40 of this wall-mounted DC charging pile are preferably manufactured using sheet metal technology. The casing 10 is fixed to the wall with expansion screws through the mounting holes on the mounting plate 50. The interior of the casing 10 is divided into a charging module cavity 90 and a control module cavity 100. This layout makes the internal wiring clear, reduces electromagnetic interference, and optimizes space utilization. The control module cavity 100 houses the control module 60. A fan assembly is installed on the left side of the aluminum heat sink of the charging module 30, and an air inlet 70 is opened on the side of the control module cavity 100. When the charging module is working, cool air enters from the bottom (i.e., the side of the charging module cavity 90) of the casing 10 of the wall-mounted DC charging pile (i.e., the left side, i.e., the air inlet 70), carrying away the heat from the heat sink. Hot air is exhausted from the bottom right side under the action of the fan assembly, forming an independent vertical heat dissipation channel isolated from the electronic components. This effectively avoids dust contamination of the electronic components of the control module and improves heat dissipation efficiency. The panel 20 serves as the maintenance door for the charging pile, secured to the housing 10 by screws on both sides. Loosening the screws allows the maintenance door to be opened upwards, enabling direct maintenance and replacement of the internal modules. The charging gun bracket 80 can be independently installed on one side of the charging pile. When the charging gun cable is not in use, it can be wound around the charging gun bracket 80 to maintain a clean environment.

Furthermore, various modifications can be made to this utility model for specific situations or materials without departing from its scope. Therefore, this utility model is not limited to the specific embodiments disclosed, but should include all embodiments falling within the scope of the claims of this utility model.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
