Description

Technical Field

[0001] This utility model relates to charging piles, and more particularly to the outer shell of an electric vehicle charging pile and the charging pile itself. Background Technology

[0002] With the booming development of the electric vehicle industry, the design and performance of the charging pile's casing are crucial as a key supporting facility. As the application scenarios for electric vehicles become increasingly diverse and widespread, higher demands are being placed on the charging pile casing in terms of functional integration, ease of use, and safety.

[0003] Currently, various designs exist for the casing of electric vehicle charging stations. For example, Chinese utility model patent application number 201120216787.7 and authorization announcement number CN 202159987 U discloses a casing for an electric vehicle charging station. This casing consists of an aluminum alloy front panel and a C-shaped barrel connected by a plug-in mechanism, offering advantages such as rust resistance, corrosion resistance, moisture resistance, and impact resistance, thus meeting the basic needs of outdoor charging stations to a certain extent. However, its functional design is relatively simple, focusing only on optimizing the casing material and structural connection method, without fully considering the convenience of storing and placing the charging gun and charging cable during charging. In actual use, users often need to organize the charging cable themselves, and the charging gun lacks a dedicated and stable placement location, easily leading to tangled and worn charging cables, and damage caused by careless placement of the charging gun, affecting the lifespan of the charging station and the user's charging experience.

[0004] Furthermore, existing charging pile casings have shortcomings in internal space layout and cable channel design. The lack of rational planning for cable routing and storage space results in cluttered internal wiring, increasing installation and maintenance difficulty and posing safety hazards such as an increased risk of short circuits. With the trend towards intelligent charging piles, more functional modules need to be integrated into the casing, a requirement that current casing designs cannot meet, thus limiting further upgrades to charging pile technology. Therefore, developing an electric vehicle charging pile casing with superior functional integration, ease of use, and safety is of significant practical importance. Utility Model Content

[0030] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described in detail with reference to the embodiments.

[0031] Example 1

[0032] The electric vehicle charging pile housing includes a front housing 1 and a rear housing 2. The front housing 1 and the rear housing 2 are fixedly connected by fasteners, which are screws.

[0033] The housing has a strip-shaped hole 10 that runs through the front housing 1 and the rear housing 2. A left channel 11 and a right channel 12 are respectively provided on both sides of the housing. The left channel 11 is used for signal lines, and the right channel 12 is used for charging lines. The strip-shaped hole 10 is located between the left channel 11 and the right channel 12. The strip-shaped hole 10 divides the housing into two channels and also reduces the weight of the housing. A chamber is located at the top of the housing, and both the left channel 11 and the right channel 12 communicate with the chamber. The left channel 11 and the right channel 12 extend through the bottom of the housing.

[0034] The top side wall of the strip-shaped hole 10 is provided with a mounting part 13 for mounting the charging gun. The lower end face of the mounting part 13 is provided with a wire hole 131 with an opening facing downward for the charging cable to enter and exit. The charging cable passes through the right channel 12 and extends into the wire hole 131 and connects to the charging gun. The side of the mounting part 13 is provided with a gun hole 132 for placing the charging gun. Both the wire hole 131 and the gun hole 132 are connected to the chamber. When not charging, the charging head of the charging gun is placed in the gun hole 132. When charging, the charging gun is taken out from the gun hole 132.

[0035] The strip-shaped hole 10 on the housing connects the front housing 1 and the rear housing 2, dividing the housing into a left channel 11 for signal lines and a right channel 12 for charging lines, thus enabling categorized wiring arrangement and reducing the weight of the housing. A chamber is located at the top of the housing, connecting both the left and right channels 11 and extending through the bottom of the housing, facilitating overall wiring layout. The mounting portion 13 on the top side wall of the strip-shaped hole 10 has a wire hole 131 on its lower end face and a gun hole 132 on its side, both communicating with the chamber. The charging line passes through the right channel 12 and extends into the wire hole 131 to connect to the charging gun. When not charging, the charging head of the charging gun is placed in the gun hole 132; when charging, it is removed from the gun hole 132. This design facilitates the placement and retrieval of the charging gun, improving the convenience and practicality of the charging station.

[0036] The mounting part 13 is hidden inside the strip hole 10. The upper end of the mounting part 13 is provided with an inclined surface 130, and the gun hole 132 is provided on the inclined surface 130. The opening of the gun hole 132 faces downward, and the gun head of the charging gun can be installed in the strip hole 10. When the gun head of the charging gun is installed in the mounting part 13, the gun head is hidden in the gun hole 132 and is in the highest position, which prevents rain and snow from wetting the gun head of the charging gun and enhances the protective performance of the charging gun. At the same time, the hidden design also makes the appearance of the charging pile more concise and beautiful, and improves the convenience and practicality of the charging pile.

[0037] The mounting part 13 is partially integrally formed on the front housing 1 and partially integrally formed on the rear housing 2. Half of the wire hole 131 is located on the front housing 1 and the other half on the rear housing 2. The plate surface containing the inclined surface 130 is integrally formed on the front housing 1. The integral forming of one part on the front housing 1 and the other part on the rear housing 2 makes the connection between the mounting part 13 and the housing more stable, effectively reducing assembly steps, significantly improving production efficiency, and lowering production costs. The wire holes 131 are evenly distributed on the front and rear housings, allowing for better fit during charging cable installation, ensuring stable cable entry and exit, and reducing the risk of line failure due to improper installation.

[0038] The top front surface of the front housing 1 has mounting holes 14 for installing a display screen, which communicate with the cavity. The mounting holes 14 provide precise positioning for the display screen installation, simplifying the installation process, reducing installation difficulty, and improving assembly efficiency. Functionally, the communication between the mounting holes 14 and the cavity facilitates wiring between the display screen and the internal circuitry of the charging pile, ensuring stable signal transmission and enabling the display screen to correctly display key data such as charging status, power information, and cost, providing users with a clear and intuitive interactive interface and enhancing user experience. Furthermore, this design maintains the integrity of the overall structure of the charging pile's casing, preventing damage to the casing's appearance due to additional display screen installation methods, thus contributing to improved overall aesthetics and practicality of the charging pile.

[0039] A number of heat dissipation holes 15 are provided on one side wall of the strip-shaped hole 10, and all heat dissipation holes 15 are connected to the right channel 12. This design, with its numerous heat dissipation holes 15 on the side wall of the strip-shaped hole 10 and connection to the right channel 12, offers significant advantages. The heat dissipation holes 15 provide additional heat dissipation pathways, allowing the internal heat of the charging pile to be quickly dissipated to the external environment, effectively preventing equipment failure due to overheating and significantly improving the stability and lifespan of the charging pile. The connection to the right channel 12 cleverly utilizes the space of the charging cable channel, achieving an organic combination of heat dissipation and wiring layout, and optimizing the internal structure of the charging pile. Simultaneously, this design avoids the impact on the structural strength of the casing caused by separately opening heat dissipation holes in other locations, ensuring the overall robustness of the charging pile's outer shell. It satisfies heat dissipation requirements while maintaining the stability and aesthetic integrity of the equipment, improving the practicality and reliability of the charging pile.

[0040] The inner walls of the rear housing 2 are provided with a number of positioning units on both sides, with a total of 20 positioning units. The positioning units include a first column 21 and a second column 22. The inner walls of the front housing 1 are provided with bolt holes and positioning grooves on both sides. The screws are threadedly connected to the first column 21 through the bolt holes, and the second column 22 is engaged in the positioning groove, thereby fastening the front housing 1 to the rear housing 2.

[0041] The rear housing 2 has 20 positioning units around its perimeter. Each positioning unit includes a first column 21 and a second column 22, which, in conjunction with the corresponding bolt holes and positioning grooves on both sides of the inner wall of the front housing 1, offer significant advantages in connection design. Regarding connection stability, the screws are threaded into the first column 21 through the bolt holes, and the second column 22 engages with the positioning groove, forming a double fastening that ensures a tight connection between the front housing 1 and the rear housing 2. This effectively prevents loosening during use and significantly improves the overall structural stability of the charging pile. From an installation convenience perspective, the positioning units and corresponding structures provide precise positioning for installation, allowing installers to quickly align components, reducing installation difficulty and improving assembly efficiency. Furthermore, this structural design distributes the stress points, enhancing the overall structural strength of the housing. While ensuring the charging pile's outer shell is robust and durable, it also helps maintain the equipment's appearance integrity, extends the charging pile's lifespan, and improves its practicality and reliability.

[0042] Example 2

[0043] Example 2 is essentially the same as Example 1, except that both the front housing 1 and the rear housing 2 have a number of grooves 20, all distributed around the strip-shaped hole 10. This clever distribution of grooves 20 enhances the strength of the housing in the relatively weak area around the strip-shaped hole 10, effectively dispersing stress and reducing the risk of deformation due to external impact or long-term use, ensuring the overall structural stability of the charging pile. In terms of heat dissipation, the grooves 20 increase the surface area of ​​the housing, helping heat dissipate more quickly. Working in conjunction with the heat dissipation holes 15 on the sidewalls of the strip-shaped hole 10, this further improves the heat dissipation efficiency of the charging pile, reducing the possibility of overheating and subsequent malfunctions. In terms of appearance design, the regularly distributed grooves 20 give the charging pile casing a more layered and stylish look. While maintaining the integrity of the device's appearance, they add a unique visual effect, enhancing the overall quality of the product, balancing practicality and aesthetics, and strengthening the charging pile's competitiveness in the market.
