Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobiles, in particular to a rear lamp with a narrow-size split decorative ring for an automobile. Background Art
[0002] When the exposed surface of the rear lamp is small, the internal space is insufficient to arrange the light source. Usually, the shell is enlarged and the excess part is hidden inside the car body. This makes it impossible to install the lamp directly from the front. The car body needs to be disassembled into multiple parts to accommodate the installation of the lamp, which makes the cost of the car body very high. There are two ways to combine thick-walled parts and decorative rings.
[0003] 1. The thick wall is directly inserted into the decorative ring. This combination requires an increased safety gap to prevent the two parts from contacting and rubbing to produce plastic powder. This gap is generally 1-1.5mm. The value is determined according to the position of the thick wall fixing point and the length of the cantilever. The longer the cantilever, the larger the safety gap needs to be. This kind of matching method can see an obvious installation gap, and the appearance is not delicate enough. 2. Thick wall and decorative ring two-color injection molding. This combination makes the two parts into a whole without installation matching gap, but the mold has restrictions on the size of the thick wall. If the thick wall is too long, it may cause the thick wall to shrink and affect the appearance and optical performance. Two-color injection molding cannot control shrinkage by increasing mold pressure, so usually the thick wall length is smaller when these two are combined (usually around 7mm). The thick wall uniform light length usually needs to be more than 40mm to meet uniformity, which leads to the need to add other parts to compensate. The increase in parts will cause the price of the entire lamp to rise. Utility Model Content
[0004] The utility model aims to provide a rear lamp with a narrow-size split bezel for an automobile, so as to solve the problems raised in the above-mentioned background technology.
