Embodiment Construction

[0033] The following description of preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention and its application or uses.

[0034] Referring generally to the drawings, the present invention generally provides an assembly comprising at least one localized reinforcement attached to at least one reinforcement, wherein infrared welding of the at least one reinforcement to at least one panels combined. The at least one panel is attachable to at least one other panel, preferably the at least one other panel comprises a Class A surface. The invention also typically provides a combination of local reinforcement to reinforcement overmoulding and infrared welding of the components. This application relates to components and methods of making the same.

[0035]Although a liftgate assembly is depicted throughout the drawings and described herein, it should be understood that an exterior body panel assembly that is any type of vehicle component...

Abstract

A liftgate assembly having finished show surfaces, and process of manufacturing same are disclosed. The liftgate assembly includes local reinforcements that are overmolded to first reinforcements, andthe first reinforcements are infrared welding to a first panel. Second and third reinforcements are also infrared welded to the first panel. To infrared weld the respective reinforcements to the first panel in predetermined locations with respect to the first panel, nesting structures are provided to hold the respective reinforcements and first panel. At least one infrared heating fixture heats various predetermined surfaces on the reinforcements and first panel, and the parts are then pressed together for joining the predetermined surfaces of the respective parts together. The process is repeated, if needed, until all of the reinforcements are infrared welded to the first panel. Outer panels are bonded to the second and third reinforcements.

Description

[0001] Cross References to Related Applications [0002] This application is a PCT International Patent Application claiming priority to US Provisional Application No. 62 / 459,928, filed February 16, 2017. The disclosures of the above applications are incorporated herein by reference. technical field [0003] The present invention relates to an exterior panel assembly for a vehicle and a method of manufacturing the exterior panel assembly. More particularly, it relates to liftgate assemblies and methods of manufacture for vehicles. Background technique [0004] Depending on the application, the automotive industry sets predetermined performance criteria such as fuel economy, durability, strength, crash performance, tension requirements, noise, vibration, or harshness, among others. One of the current trends in the automotive industry is to try to reduce quality and investment costs. However, many existing lift doors use metal reinforcements that are either mechanically att...
