Problems solved by technology

However, when parts made of resin materials are joined to each other by ultrasonic welding, the resin melted at the interface remains at the interface, making it difficult to control the thickness of the interface, or the joint strength may become unstable.

Embodiment Construction

[0042] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In addition, in this specification and drawings, the same code|symbol is attached|subjected to the structural element which has substantially the same function structure, and a repeated description is abbreviate|omitted. In addition, in the present specification and the drawings, a plurality of constituent elements having substantially the same functional configuration may be distinguished by attaching different letters to the same symbol. However, when there is no need to particularly distinguish a plurality of components having substantially the same functional configuration, only the same symbols are attached.

[0043]

[0044] First, the configuration of a resin member according to an embodiment of the present invention will be described. The resin component is a component to be joined to a joining target component by ultrasonic welding. Ultras...

Abstract

The present invention provides a resin member capable of controlling a position and an amount of molten resin produced during the ultrasonic welding, and stabilizing the thickness of the interface so as to stabilize the bonding strength. A resin member contains a thermoplastic resin and is bonded to another resin member by ultrasonic welding. The resin member includes projections that are projected from a surface of a bonding target section of the resin member and melted by application of contact pressure during the ultrasonic welding. The projections include projections having different projection heights from the surface of the bonding target section.

Description

technical field [0001] The present invention relates to resin parts comprising a thermoplastic resin and joined to each other by ultrasonic welding. Background technique [0002] Conventionally, structural parts of automobile bodies are made of metal materials such as steel. In recent years, in order to reduce the weight of the vehicle body, the use of structural parts made of resin materials such as carbon fiber mixed fiber reinforced resin (CFRP) has gradually been realized. As a joining method for joining members made of metal materials, there are basically three methods. One is outfitting joining using bolts or the like, the other is bonding using an adhesive, and the other is fusion joining by melting metals. When a component is made of a resin material, the same strong joint as that of a member made of a metal material is required. In particular, in the case of components made of a resin material including a thermoplastic resin, a welding technique of melting and jo...
