Description

Technical Field

[0001] This utility model relates to the field of glass lenses, and in particular to a car headlight glass lens with high installation stability. Background Technology

[0002] Automotive headlights, also known as front headlights, are the core lighting device for vehicles at night. They generally consist of a mounting base, a bulb, a reflector, and a glass lens. The glass lens is usually an aspherical convex lens, which can focus the light emitted by the bulb, allowing the light to illuminate the road ahead more effectively.

[0003] When installing a glass lens, the glass lens needs to be pressed into the front end of the mounting base so that the ring-shaped claws on the mounting base hold the glass lens in place. When the glass lens is round, its edges are also round. Relying solely on the pressure of the claws on the glass lens is insufficient to guarantee that the glass lens will not rotate during vehicle use. Furthermore, the focusing effect of an aspherical convex lens will change after rotation, thus affecting the light pattern and illumination effect.

[0004] Therefore, existing circular glass lenses suffer from poor installation stability. Utility Model Content

[0005] The purpose of this invention is to provide an automotive headlight lens with high installation stability. This invention has the advantage of high installation stability.

[0006] The technical solution of this utility model is as follows: A car headlight glass lens with high installation stability includes a mounting base and a circular convex lens body; the front end of the mounting base is provided with a lens hole, and multiple positioning protrusions are provided in a ring evenly distributed manner inside the lens hole; a horizontally extending inward mounting ring is provided on the lens hole, and multiple ring evenly distributed mounting holes are provided on the mounting ring; the edge of the lens body is provided with a horizontally extending outward side, and a positioning notch is provided on the side edge corresponding to the position of each positioning protrusion, and a positioning hole is provided on the side edge corresponding to the position of each mounting hole; a plastic expansion tube is fitted and engaged in the positioning hole, and a screw with its end locked outside the mounting hole is threaded into the plastic expansion tube.

[0007] In the aforementioned automotive headlight glass lens with high installation stability, both the outer side of the side and the side protruding towards the lens body are frosted.

[0008] In the aforementioned automotive headlight glass lens with high installation stability, the positioning hole has a frosted finish.

[0009] In the aforementioned automotive headlight glass lens with high installation stability, the thickness of the side is 5-8 mm; and the thickness of the mounting ring is 10-15 mm.

[0010] Compared with the prior art, this utility model has a horizontally inwardly extending annular mounting ring at the lens hole at the front end of the mounting base, and a horizontally outwardly extending annular side on the edge of the circular convex lens-shaped lens body. The side can be engaged with the rear side of the mounting ring, and the positioning notch and positioning protrusion can cooperate to position the lens body in the mounting base, and the lens body is not easy to rotate relative to the mounting base. Then, by screwing a plastic expansion tube through the mounting hole into the positioning hole, the lens body can be stably fixed on the mounting base, and the installation operation is more convenient.

[0011] In addition, the outer side of the lens body and the side protruding towards the lens body are both frosted, resulting in greater friction between the lens body and the mounting base, which further improves the installation stability of the lens body.

[0012] By setting the positioning hole with frosted material, the friction between the positioning hole and the plastic expansion tube is increased, making it less likely for the plastic expansion tube to rotate relative to the positioning hole when the screw is screwed into it.

[0013] The thickness of the side is 5-8mm, and the thickness of the mounting ring is 10-15mm. It has good structural strength and good durability.

[0014] Therefore, this utility model not only improves installation stability, but also has the advantages of convenient installation and operation and good durability. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0021] Example. A car headlight glass lens with high installation stability, configured as follows: Figures 1 to 4As shown, the lens includes a mounting base 1 and a circular convex lens-shaped lens body 2. The mounting base 1 has a lens hole 3 at its front end, and multiple positioning protrusions 4 are evenly distributed in a ring inside the lens hole 3. A mounting ring 5 extending horizontally inward is provided on the lens hole 3, and multiple mounting holes 6 are evenly distributed in a ring on the mounting ring 5. The edge of the lens body 2 has a side edge extending horizontally outward, and a positioning notch 8 is provided on the side edge 7 corresponding to the position of each positioning protrusion 4. A positioning hole 9 is provided on the side edge 7 corresponding to the position of each mounting hole 6. A plastic expansion tube 10 is fitted and engaged in the positioning hole 9, and a screw 11 with its end locked outside the mounting hole 6 is threaded into the plastic expansion tube 10.

[0022] Both the outer surface of the side 7 and the side facing the lens body 2 are frosted.

[0023] The positioning hole 9 has a frosted finish.

[0024] The thickness of the side 7 is 5-8 mm; the thickness of the mounting ring 5 is 10-15 mm.

[0025] Working principle: Insert the lens body 2 into the lens hole 3 from the mounting base 1 with the protruding side of the lens body 2 protruding from the lens hole 3, and the side edge 7 on the lens body 2 is engaged inside the mounting ring 5; according to the lighting requirements, engage the positioning notch 8 on the side edge 7 with the positioning protrusion 4 at the lens hole 3, so that the lens body 2 is stably assembled at the lens hole 3; then, pass the screw 11 from the outside to the inside through the mounting hole 6 and screw it into the plastic expansion tube 10 in the positioning hole 9, so that the plastic expansion tube 10 is well engaged in the positioning hole 9, and the lens body 2 and the mounting base 1 are stably installed.

[0026] The outer surface of side 7 and the side protruding towards the lens body 2 are both frosted, resulting in greater friction between the lens body 2 and the mounting base 1, thus improving installation stability. The interior of the positioning hole 9 is also frosted, preventing the plastic expansion tube 10 from rotating relative to the positioning hole 9 when the screw 11 is screwed into it, making the screwing operation easier. The thickness of side 7 is 5–8 mm, and the thickness of the mounting ring 5 is 10–15 mm, resulting in good structural strength and durability.
