AI Technical Summary

⚠Technical Problem

Traditional light glass clip structures are prone to slippage and deformation in their large sloping surface design, leading to unstable installation, positioning deviations, sinking, and glue leakage.

⚗Method used

The design of the lamp housing and lamp glass is such that the positioning points are perpendicular to the pressing direction, and the positioning pin moves linearly along the pressing direction when it is inserted into the groove. Combined with the design of the glue groove, a multi-directional fixing system is formed to enhance installation stability.

🎯Benefits of technology

It effectively avoids plastic deformation of the clips due to non-axial force, improves the installation stability of the large-sloping lamp glass, prevents glue leakage, and ensures a firm connection between the lamp glass and the lamp housing.

Abstract

The application provides a lamp fastening positioning device and a vehicle lamp. The lamp fastening positioning device comprises a lamp shell and a lamp bulb. The lamp shell forms a spaced fastening hole and a groove. The depth direction of the groove is perpendicular to the axial direction of the fastening hole. The tail inclined surface of the lamp bulb forms a positioning clamping point coaxially clamped in the fastening hole and a positioning pin shaft synchronously clamped in the groove. The protruding direction of the positioning clamping point is parallel to the axial direction of the positioning pin shaft. The pressing direction of the lamp bulb is perpendicular to the protruding direction of the positioning clamping point and parallel to the depth direction of the groove. In addition, the application also provides a vehicle lamp comprising the aforementioned lamp fastening positioning device. The application can solve the technical problem of poor installation stability of large inclined surface lamp bulbs in the prior art.
