In today’s popular new energy vehicles, electric vehicle charging piles are not only charging tools, but also “technology symbols” and brand touchpoints on urban streets. This article will dismantle the design logic of the six typical charging piles in the diagram, from the source of appearance inspiration to the realization of sheet metal parts, and take you to establish a complete industrial design thinking system.
1. Appearance design: use visual language to convey functions and brands
1. Future technology wind (Figures 1, 3, 6)
• Inspiration: Cyberpunk aesthetics and capsule design
• Visual logic:
◦ Color: Dark gray / black base + fluorescent (orange, cyan) lines, simulating the energy flow in science fiction movies, hinting at the core function of “fast charging“.
◦ Form: The angular cutting surface + arc transition not only retains the sense of power of industrial equipment, but also weakens the cold feeling through curved surfaces, which is in line with the technological tonality of future travel.
◦ Ambient lights: LED strips throughout the body not only improve night recognition, but also provide intuitive feedback on the charging status (e.g., green for full, orange for charging) through breathing lighting effects.
2. Minimalist urban style (Figures 2 and 4)
• Source of inspiration: the minimalism of modern architecture and the sophistication of high-end appliances
• Visual logic:
◦ Color: Pure white/light gray as the main color, with thin green decorative bands, conveying the brand concept of “environmental protection and cleanliness”, suitable for commercial buildings, high-end communities and other scenarios.
◦ Form: Vertically integrated shape + hidden interface to reduce visual redundancy and allow the device to naturally integrate into the urban landscape.
◦ Details: Flush seams without screws and matte sheet metal finishes enhance overall sophistication.
3. Stabilize industrial style (Figure 5)
• Inspiration: The reliability of heavy construction machinery and the durability of outdoor facilities
• Visual logic:
◦ Color: Dark gray + black heavy color scheme, with orange warning signs, clearly distinguishing the operating area, in line with the safety specifications of outdoor equipment.
◦ Shape: Square cabin structure + widened base to enhance visual stability and cope with complex outdoor wind and collision risks.
◦ Material: Adopts wear-resistant fluorocarbon spraying process to improve UV resistance and corrosion resistance.
2. Structural parts: let the idea land into a manufacturable sheet metal product
1. Future technology wind charging station (take Figure 3 as an example)
• Segmentation logic: Modular splitting by functional area, taking into account both aesthetics and maintainability
1. Front panel module: adopts double-layer sheet metal structure, the outer layer is a decorative panel with dot matrix texture, the inner layer is a functional back panel, and the charging interface and control screen are integrated; The dot matrix hole not only meets the heat dissipation needs, but also becomes a visual highlight.
2. Side guard module: symmetrical curved sheet metal parts, formed by bending, embedded with LED light strips, and light guide grooves are reserved during the design stage.
3. Base module: independent sheet metal frame, internal installation of counterweight block and grounding device, and bolted connection with the main body, easy to level and maintain on site.
4. Top Decorative Cover: Stamped curved sheet metal to cover the equipment’s electrical component compartment and quickly disassemble through a snap structure.
• Process points: The fluorescent color lines adopt the “secondary spraying + high-temperature curing” process to ensure color adhesion; The arc corners are bent once with a special mold to avoid splicing welds.
2. Minimalist urban style charging Charging Hub (take Figure 4 as an example)
• Piece logic: With “hidden” as the core, visual integration is realized
1. Main cabin: Sheet metal frame with integrated bending molding, matte spraying on the surface, and stepped design at the joints to avoid misalignment.
2. EV Charging interface hatch: with hidden hinge design, flush with the panel when closed; The interior of the hatch has an integrated waterproof rubber strip that meets IP54 protection.
3. Control screen bracket: tilting design, connected with the main body through a damping shaft, adjustable angle to improve operating comfort; The wire path is reserved inside the bracket.
4. Bottom guard: Detachable design, covering the grounding and cable interface, fixed with hidden screws to keep the vision tidy.
• Key points of the process: the green decorative tape is anodized aluminum profile, which is spliced with the sheet metal panel through the card slot, which is more durable than glue; The strip is embedded within the sheet metal groove, allowing for uniform light through the light guide plate.
3. Stable industrial wind charging options (take Figure 5 as an example)
• Piecework logic: With “durability” as the core, it adapts to complex outdoor environments
1. Main frame: welded by square tube, covered with sheet metal guard; The guard adopts the “internal stiffener + outer skin” structure to improve the ability to resist deformation.
2. Charging gun mount: independent parts, thickened sheet metal stamping and forming, and the surface is treated with anti-slip texture to ensure that the charging gun is placed firmly.
3. Heat dissipation system: The top and bottom are designed with louvered heat dissipation holes to achieve natural heat dissipation through air convection; The hole is designed with a waterproof inclination angle to avoid rainwater entering.
4. Warning sign area: Reflective film screen printing process is adopted, which is more wear-resistant than traditional painting and can still maintain high recognition under strong light.
• Process points: corrosion protection should be considered for outdoor installation, and all sheet metal parts are protected by hot-dip galvanizing + fluorocarbon spraying; The base is fixed with expansion bolts to the ground to ensure wind resistance level 12.
3. Advanced design thinking: the core principles of charging pile design
1. Scenario adaptation: Different scenarios (such as business districts, residential areas, and high-speed service areas) have different requirements for appearance and function, so it is necessary to fully investigate the user behavior and environmental characteristics of the target scenario before designing.
2. Protection first: As outdoor electrical equipment, the electric car charging pile has IP protection level (waterproof, dustproof), impact resistance, and UV resistance as the bottom line of structural design.
3. Modular reuse: The same product line should use the same component logic and process standards as much as possible to reduce production costs and maintenance difficulties.
4. User experience: The height of the operating area, the angle of the screen, and the plugging and unplugging force of the charging cable directly affect user satisfaction and need to be simulated and verified during the design stage.
