Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to a connection structure for lightweight automotive lighting aluminum components. Background Technology

[0002] As the automotive industry rapidly develops towards lightweighting, energy conservation, environmental protection, and intelligentization, the structural design of headlights, as a core component of a car's appearance and function, has an increasingly significant impact on overall vehicle performance. Traditional headlight housings are mostly made of plastic, which, while offering advantages such as low cost and ease of molding, suffers from poor weather resistance and insufficient strength in long-term use, making it difficult to meet the dual requirements of durability and lightweight design for high-end models.

[0003] While there are existing technologies that use aluminum components to manufacture vehicle headlight connection structures, these still suffer from issues such as poor quality, low assembly efficiency, and difficulty in positioning, thus necessitating improvements. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a lightweight connection structure for aluminum automotive lamp components, so as to solve the problems of the above-mentioned aluminum automotive lamp connection structures.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a lightweight automotive lamp aluminum component connection structure, including an aluminum connecting seat and a lamp head. The connecting seat is designed as a thin sheet, with a circular assembly opening stamped at the center. The edge of the assembly opening is formed with a downwardly bent connecting ring. The lamp head is used to assemble the automotive lamp glass cover and electrical contacts. The lamp head includes a top cover and a connecting sleeve. The top cover is located at the top opening of the connecting sleeve and is airtightly connected by welding. The top cover has an opening at its center for assembling the automotive lamp glass. The connecting sleeve is filled with waterproof insulating glue. The bottom of the connecting sleeve has multiple contact pieces. After the contact pieces are cured with waterproof insulating glue, they are firmly installed on the bottom surface of the connecting sleeve and protrude from the bottom surface of the connecting sleeve for external power supply to the lamp core inside the automotive lamp glass. The connecting sleeve is inserted into the inner ring of the connecting ring, and the two are interference-fitted and connected by soldering.

[0006] In a further technical solution, the thickness of the connector is 0.3mm-0.7mm.

[0007] In a further technical solution, the central part of the connecting seat is stamped to form an arched portion, and the assembly opening is formed at the center of the supply portion; a circular connecting side is formed on the outer side of the arched portion.

[0008] In a further technical solution, the bottom surface of the arched portion and the outer surface of the connecting ring surround each other to form a positioning groove for sleeve installation.

[0009] In a further technical solution, a flat angle is formed on one side of the arched portion, which is used as the positioning and installation angle for the headlights.

[0010] In a further technical solution, two connecting holes are punched on the side of the connecting side near the flat corner, and external flaps for bending and fastening installation are left on the outside of the connecting holes.

[0011] In a further technical solution, the connecting hole is rectangular; the outer flap matches the connecting hole.

[0012] In a further technical solution, the periphery of the connecting side is formed by punching outwardly protruding positioning fins. There are three positioning fins, which are distributed at intervals along the circumference.

[0013] In a further technical solution, the projection shape of the positioning fin is set in a rectangle.

[0014] In a further technical solution, the protruding length of the positioning fin is 5mm-8mm and the width is 3mm-5mm.

[0015] The advantages of this invention compared to the prior art after adopting the above structure are: 1. The connector adopts a thin sheet design and uses a stamping process to integrally form the arched part, connecting ring and positioning fins, which greatly reduces the amount of material used, significantly reduces weight, and improves the level of lightweighting.

[0016] 2. The connecting sleeve and the connecting ring are connected by soldering after being inserted with an interference fit. The assembly steps are simplified to two steps: insertion and soldering, which shortens the assembly time. Furthermore, the connecting sleeve and the connecting ring are pre-fixed by an interference fit before being soldered together.

[0017] 3. The pre-set positioning fins and flat-angled positioning structure on the connector enable quick and precise alignment of the headlights, avoiding the need for repeated angle or position adjustments required by traditional structures, thus further improving assembly efficiency. 4. The connector is integrally formed using a stamping process, eliminating the need for additional machining or welding pretreatment. This keeps mold costs under control and increases production efficiency. The design of the outward-flaring tabs and rectangular connecting holes facilitates bending and fastening installation, further simplifying the fixing process with the headlight bracket.
