Description

Technical Field

[0001] This utility model relates to the technical field of car charging pile equipment, and in particular to a wall-mounted DC charging pile. Background Technology

[0002] Electric vehicles rely on charging systems for energy support; these systems are the cornerstone of normal operation and a core element in promoting the commercialization and large-scale development of the electric vehicle industry. Among various charging facilities, AC charging stations play a crucial role, serving not only as the foundation for electric vehicle development but also as a key to improving social and economic benefits. The construction and development level of AC charging stations directly affects the popularity of electric vehicles and the overall development trend of the industry.

[0003] However, existing outdoor AC charging stations using spiral cables suffer from problems after long-term outdoor use, such as the spiral cables becoming covered in dirt and dust, making them difficult to clean, and the daily storage of the spiral cables becomes a challenge. Utility Model Content

[0004] The purpose of this invention is to provide a wall-mounted DC charging station to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wall-mounted DC charging station includes: a wall-mounted charging station, a charging gun, and a cable connecting the wall-mounted charging station and the charging gun.

[0007] The cable includes a front cable segment suitable for concealed installation and a coiled cable segment.

[0008] The helical spring cable segment is equipped with a portable cleaning and storage component.

[0009] The portable cleaning and storage assembly includes a cable storage tube that runs vertically through the top and bottom, and a gun head locking seat for securing the charging gun. The gun head locking seat is fixedly connected to the top of the cable storage tube.

[0010] The cable storage cylinder has a through-type cleaning groove on its wall for high-pressure water gun cleaning, and a drainage structure at the bottom. During cleaning, the helical spring cable segment retracts into the cable storage cylinder, facilitating concentrated cleaning by the high-pressure water gun. The cable segment can be rinsed from top to bottom through the cable storage cylinder, or horizontally through the through-type cleaning groove on the side. The cable storage cylinder provides neat storage and, compared to rinsing cables in an open environment, effectively prevents water splashing during cleaning, improves cable rinsing efficiency, and saves water.

[0011] Preferably, the gun head connector is fixedly connected to the top of the cable storage tube via an L-shaped connector.

[0012] Preferably, the L-shaped connector includes an integrally formed horizontal support platform and a vertical support platform; the vertical support platform is provided with the gun head latch; and the horizontal support platform is fixedly connected to the top of the cable storage tube.

[0013] Preferably, the top of the vertical support platform is also fixedly provided with a U-shaped rain cover extending towards the gun head mounting seat.

[0014] Preferably, the cable storage tube includes a main body, an opening detachably connected to the top of the main body, and a chassis detachably connected to the bottom of the main body; the drainage structure consists of a plurality of drainage holes formed on the chassis.

[0015] Preferably, the opening has a funnel-shaped structure.

[0016] Preferably, the main body, the opening, and the chassis are connected by threads.

[0017] Preferably, the outer wall of the cable storage tube is also provided with no less than two connecting beams for fixing to the wall.

[0018] Preferably, the front-end cable segment is configured as a conduit that can be buried in a wall or underground.

[0019] Compared with the prior art, the wall-mounted DC charging pile of this application has the following advantages:

[0020] 1. Easy to clean and maintain: With a cable storage tube featuring a through-type cleaning tank and a bottom drainage structure, users can quickly and centrally clean the helical spring cable section using a high-pressure water gun. During cleaning, the water flow can penetrate the cleaning tank from top to bottom or horizontally, effectively washing away dirt and dust adhering to the cable surface. The cleaning efficiency is high, and it avoids water splashing everywhere, saving water. It is especially suitable for daily maintenance in dusty and muddy outdoor environments.

[0021] 2. Neat Storage and Space Optimization: The cable storage tube provides a dedicated space for the spiral spring cable segment, and the charging gun can be securely placed through the gun head connector, preventing the cable from being dragged, tangled, or piled up on the ground, improving the neatness and safety of the equipment, while saving installation space.

[0022] 3. Rational structure and flexible installation: The detachable cylindrical structure (e.g., the main body, opening, and chassis are connected by threads) and the wall-mounted connecting beam design facilitate transportation, on-site assembly, and adjustment of the installation position. The front-end cable section can be concealed in the wall or underground, further maintaining an aesthetically pleasing environment.

[0023] 4. Enhanced outdoor durability and ease of use: The U-shaped rain cover effectively prevents rainwater from directly wetting the charging gun interface, improving the long-term durability of the equipment in outdoor environments. The funnel-shaped opening helps guide the cable smoothly when extending and retracting, reducing friction loss and extending cable life.

[0024] 5. Overall functionality is well-coordinated and highly practical: The charging gun socket and cleaning and storage structure are integrated into one unit, which not only realizes the functions of cable storage and cleaning, but also makes it easy for users to plug and unplug the charging gun, improving the convenience of operation and the overall integration of the equipment.
