Ford’s latest European Patent Office application describes an innovative hood design tailored for vehicles like EVs, where routine maintenance is less frequent. Unlike traditional hoods with complex hinges, intricate catches, and stays to hold them open, Ford’s design simplifies the process. This hood slides along tracks and can be easily unhooked, eliminating traditional hinges entirely.
Simple, Removable Hood
Anyone remembering the Smart microcar marketed in the States by Mercedes-Benz might recall that the Mk2 Smart had detachable plastic body panels, so you could theoretically swap them out for another color. This included a quick-release hood, which you could detach in a few seconds and remove completely. It made it easier to get to the maintenance points under the hood, such as coolant and brake fluid. The hood had no traditional hinges; it simply unhooked and could then easily be lifted out.
Ford’s proposal for a removable hood comprises a simplified attachment system with a front latch and hinge-like mechanisms at the rear – not actual hinges with pins – that detach easily. It also has guiding surfaces to ensure smooth longitudinal movement and, at the same time, ensure precise lateral location and no undesired lateral movement. Ford says that the mechanism will be easy to use and will incorporate safety features for safe operation. Its simplicity will also make it cheaper to manufacture.
Practical Solution for Cheap and Maintenance-Friendly Vehicles
Ford’s new hood design is most practical for vehicles prioritizing cost-effectiveness, infrequent hood access, or simplified maintenance. It would make the most sense on EVs that have mechanical parts and service points under the hood instead of a frunk. Many modern EVs have frunks in the nose, and therefore require traditionally hinged hoods that stay open automatically via gas struts or springs. It could also appeal to entry-level vehicles for its affordability and commercial vehicles like the Ford Transit EV.
