Abstract
A vehicle lamp includes a lamp housing having an inner space and a welding surface, and a cover that covers the inner space and is joined to the lamp housing by laser welding to be disposed adjacent to another vehicle lamp. The cover includes a design surface portion and a welding leg. An end portion of the outer peripheral portion of the design surface portion on another vehicle lamp side is provided as an adjacent side end portion. The welding leg includes a facing surface portion that protrudes from the adjacent side end portion and faces the other vehicle lamp. The facing surface portion is provided at a position extending from an upper end portion to a lower end portion of the adjacent side end portion.
Claims7
A vehicle lamp comprising:
- a lamp housing having an inner space and an annular frame where a welding surface is formed, and
- a cover configured to cover the inner space and be joined to the lamp housing by laser welding to be disposed adjacent to another vehicle lamp,
- wherein the cover includes a design surface portion that has an outer surface facing an outside of a vehicle and is partially welded to the welding surface, an inner surface facing the inner space, and a welding leg that protrudes from the inner surface adjacent a portion of an outer peripheral portion in the design surface portion and is welded to the welding surface,
- an end portion of the outer peripheral portion in the design surface portion on a side of the another vehicle lamp is provided as an adjacent side end portion, the adjacent side end portion being positioned between an upper end portion of the cover and a lower end portion of the cover opposite the upper end portion,
- the welding leg includes a facing surface that protrudes from the adjacent side end portion and faces the another vehicle lamp, an upper side portion that is continuous with the upper end portion of the cover, and a lower side portion that is continuous with the lower end portion of the cover,
- the facing surface of the welding leg is provided at a position extending from the upper end portion to the lower end portion of the cover along the adjacent side end portion,
- the upper side portion and the lower side portion extend along an upper edge and a lower edge of the cover, respectively, in a direction opposite to the facing surface,
- wherein the upper end portion of the cover comprises an inclined portion and a planar portion and the lower end portion of the cover comprises an inclined portion and a planar portion, respectively,
- wherein the planar portion of the upper end portion is extended along an upper corner of the cover so as to form an L-shape, and the planar portion of the lower end portion is extended along a lower corner of the cover so as to form another L-shape,
- wherein a joining surface of the welding leg facing the welding surface includes a first joining portion, a pair of second joining portions continuous to upper and lower portions of the first joining portion and being inclined relative to the first joining portion, and a pair of third joining portions continuous to the pair of second joining portions and forming upper and lower end portions of the joining surface continuous with the facing surface, and
- wherein the upper side portion and lower side portion include a pair of fourth joining portions continuous to the third joining portions and extending in a direction perpendicular to the third joining portions, the fourth joining portions being positioned in the same plane as the third joining portions.
