Abstract

A double-curved-surface headlamp structure is characterized in that: a lampshade is in sealed connection with the lamp body through a sealing rubber ring and screws for fixing the lampshade; a front glass fiber reinforced plastic structure is provided with a leg; the lamp body and the leg are in sealed fixation through the screws for fixing the lamp body and sealant; and two curved surfaces of the lamp body are matched with the curved surfaces of the front glass reinforced plastic structure. According to the double-curved-surface headlamp structure, self sealing of the lamp body is realized through the sealing rubber ring and the fixing screws between the lampshade and the lamp body. Self sealing grade of the lamp body can reach IP65. Sealing of automotive glass fiber reinforced plastic is realized through horizontally equipping the leg on the front glass fiber reinforced plastic structure, performing gluing sealing between the headlamp and the leg and mounting the fixing screws. After a glass fiber reinforced plastic lamp socket mold is produced, the mold is mailed to a lamp manufacturer. The lamp manufacturer manufactures the lamp mold for realizing matching of double curved surfaces and ensuring matching of the two curved surfaces and the glass fiber reinforced plastic according to a curved-surface-shaped line.

Description

The hyperboloid head lamp structure

Technical field

The utility model relates to a kind of railcar hyperboloid head lamp structure.

Background technology

Existing vehicle has only the headlamp of single-curved surface structure; Just need two curved surfaces to cooperate with glass fibre reinforced plastic structure simultaneously after changing into hyperboloid; Present existing headlamp can not satisfy structural requirement, so need the headlamp of a kind of new type double curved-surface structure of exploitation, need consider the water proofing property and the aesthetic property that cooperate front end; Most importantly the space that is provided with of hyperboloid structure lamp is affected, and also will consider the illumination requirement of test vehicle.

The utility model content

The purpose of the utility model provides a kind of satisfy industrial design and user's needs, designs a kind of attractive in appearance, firm, waterproof and is convenient to operation, maintenance again, satisfies the headlamp of illumination requirement simultaneously again.

For realizing above-mentioned purpose; The utility model provides a kind of hyperboloid head lamp structure; It is characterized in that: be tightly connected with screw through O-ring seal and fastening lampshades between lampshade and lamp body; The front glass steel construction is provided with a horse leg, and with screw and fluid sealant sealing and fixing, two curved surfaces of lamp body and front glass steel construction curved surface are identical through fixed lamp body for lamp body and horse leg.

The utility model is realized guaranteeing the sealing of lamp body self can making lamp body self seal grade reach IP65 through the hold-down screw between the O-ring seal between lampshade and lamp body and lampshade and lamp body; Crouch one " horse leg " through the front glass steel construction, headlamp is played the glue sealing and is installed and fixed the sealing that screw is realized car body fiberglass with " horse leg "; After fiberglass socket mould comes out, post to light fixture producer to mould, the light fixture producer tool mould of turning on light is realized bi-curved cooperation, guarantees that two curved surfaces and the glass steel capital coincide by the curved line.
