Lamp housing assembly with high sealing performance

Abstract

The invention discloses a lamp shell assembly with high sealing performance. The lamp shell assembly comprises a shell with an opening in the outer end and a lampshade for sealing the shell; the lampshade comprises a body and a welding portion which is located at the edge of the body and welded to the outer end face of the shell; the body is provided with a lampshade outer wall and a lampshade side wall extending towards the shell from the lampshade outer wall; the welding portion comprises a first welding side and a second welding side, wherein the first welding side extends outwards from the lampshade side wall in the radial direction and is totally in an annular shape, and the second welding side extends towards the shell from the first welding side; and after the first welding side is attached to the outer end face of the side wall of the shell, ultrasonic welding is adopted; and after the second welding side is attached to the outer side face of the side wall of the shell, ultrasonic welding is adopted. The lamp shell assembly with the high sealing performance is better in sealing performance, and the service life of an automobile ground lighting lamp is prolonged.

Description

technical field [0001] The invention relates to a lamp housing assembly with high sealing performance. Background technique [0002] Car floor lamps, as the name suggests, are used to illuminate the ground around the car when the owner is not in the car, and its function is to facilitate the owner to observe the surrounding environment of the car. Existing automobile floor lamps are generally located on the bottom surface of the car door. When the car owner opened the door, the automobile floor lamp was on, and when the car door was closed, the automobile floor lamp went out. In this way, the ground clearance of the floor lamp is small, and the illumination area of ​​the floor lamp is very narrow, which can only illuminate the position below the car door, and cannot effectively illuminate other places around the car. The structures of floor lamps are relatively complicated, resulting in longer assembly time and higher manufacturing costs. Moreover, the sealing performance ...

AI Technical Summary

Problems solved by technology

In this way, the ground clearance of the floor lamp is small, and the illumination area of ​​the floor lamp is very narrow, which can only illuminate the position below the car door, and cannot effectively illuminate other places around the car. The structure of floor lamps is relatively complex, resulting in longer assembly time and higher manufacturing costs

Moreover, the sealing performance between the lamp housings of the existing automotive floor lamps is poor. When it rains, the use time will be unbalanced at any time, and the sealing performance of the lamp housing will gradually decrease. Rainwater may enter the lamp housing and damage the internal circuit.
