The present invention in general relates to a vehicle roof assembly and, more particularly to a removable vehicle roof with a water management system and improved sealing to prevent water and moisture infiltration.
Vehicles are generally constructed around a frame, where a vehicle's finished surface panels are secured or bonded to substructures to form body panels that are designed for attachment to the irregular surfaces of the frame. These structures typically include a finished surface outer panel bonded at multiple points to a structural inner panel that may be stamped from sheet metal or formed from composite materials such as SMC. The periphery of outer panel (outer skin) and structural inner panel are typically bonded together at the edges.
Vehicles with removable hard top panels, especially for sport utility vehicles (SUV) and jeeps have become increasingly popular. The removable nature of the hard top panels requires weather-stripping and a water management system with a discharge path to direct water to a vehicles' exterior thereby ensuring the vehicles occupants remain dry from rain and snow.
However, existing designs for sealing removable vehicle hardtop panels are not always affective and are prone to failure overtime, thereby leading to incursion of moisture to a vehicle interior. The moisture incursion is pronounced where the removable panels join together with each other and with the non-removable portion of a vehicle roof. Furthermore, existing designs for removable vehicles roof tops are cumbersome, often requiring tools and/or more than one user to install and remove the roof, and only provide a single installation configuration, thereby limiting customization and utility of the roof system.
Thus, there exists a need for an improved removable roof system that is easily configurable by a single user and that provides a seal that prevents incursion of moisture to a vehicle interior.
The present disclosure provides a vehicle removable roof system that includes a fixed vehicle structure, one or more removable panels configured to engage with the fixed vehicle structure, and a water management system positioned between the one or more removable panels and the fixed vehicle structure. The removable panels may be formed of a composite sandwich panel assembly, which may include an open area core defining a plurality of pores, a high gloss surface sheet adhered to a first face of said open area core by a first adhesive layer, and a structural skin adhered to a second side of said open area core by a second adhesive layer. The removable panels are configured for installation to and removal from the fixed vehicle structure by a single user and without the use of tools.
The present invention is further detailed with respect to the following drawings that are intended to show certain aspects of the present invention, but should not be construed as a limit on the practice of the present invention.
The present invention has utility as improved removable roof system that is easily configurable by a single user and that provides a seal with improved moisture resistance and edges suitable for sealing the removable roof assembly to other vehicle components. Embodiments of the inventive vehicle removable roof system offer improved manufacture and long term performance reliability over previous designs.
