AI Technical Summary

Technical Problem

Conventional vehicle light-emitting emblems face design constraints due to visible burrs formed during the welding of the lens and housing components, which are integrated to prevent water and dust intrusion, necessitating an ornamental part to conceal these burrs, thereby reducing design freedom.

Method used

A vehicle light-emitting emblem design where the housing has an accommodation space at its outer edge to contain resin overflow from the welding joint, and the welding regions have a tapered protrusion shape to facilitate easier integration and suppress burr formation, eliminating the need for a separate ornamental part.

Benefits of technology

The design enhances aesthetic appeal by preventing burrs from being visible and increasing design freedom, allowing for more creative emblem configurations without additional covering elements.

Abstract

To provide technology that can further improve the design aesthetics of illuminated emblems for vehicles. [Solution] It comprises a light-emitting device 8 having a light source 80 that emits light forward, a resin lens 2 having light-transmitting properties and positioned in front of the light-emitting device 8, and a resin housing 3 positioned behind the light-emitting device 8. The lens 2 and the housing 3 are integrated by welding with the first welding region 21 of the lens 2 and the second welding region 32 of the housing 3 facing each other. The vehicle light-emitting emblem 1 has a housing 3 having a receiving space 36 on its outer edge that is connected to the joint between the first welding region 21 and the second welding region 32.
