Abstract

The invention discloses a mounting structure of an automobile back door lamp. The mounting structure comprises the back door lamp, a back door outer plate and a back door inner plate. The back door outer plate and the back door inner plate are buckled; an inward-concave box body formed by integral punching is arranged on the back door outer plate, the shape of the edge of the inward-concave box body is consistent with the shape of the edge of the back door lamp, and a back door lamp positioning mounting plate is arranged on the edge of one side of the inward-concave box body. The edge of one side of the back door lamp is fixedly connected with the back door outer plate and the back door inner plate at the back door lamp positioning mounting plate through bolts, and the edge of the back door lamp is matched with the edge of the inward-concave box body. According to the mounting structure of the automobile back door lamp, the phenomenon that rainwater permeates into the position between the back door outer plate and the back door inner plate can be avoided, and meanwhile the matched appearance of the position between the back door lamp and the back door outer plate is improved.

Description

Automobile back door lamp-mounting structure

Technical field

The present invention relates to the mounting structure between automobile body components, be specifically related to the mounting structure between automobile back door light fixture and the inside and outside plate of tailgate.

Background technology

Mounting structure between existing automobile back door light fixture and the inside and outside plate of automobile back door as shown in Figure 3, comprise tailgate light fixture 1, tailgate outside plate 2, backdoor inner plate 3 and independently lamp installation box 5, tailgate outside plate 2 has a tailgate outside plate light fixture coupling face 24, lamp installation box 5 has a lamp installation box face of weld 51 and a mounting box lamp installation face 52, lamp installation box 5 and tailgate outside plate 2 to mate face 24 by mounting box face of weld 51 and to be welded tailgate outside plate assembly with tailgate outside plate light fixture, then fasten with backdoor inner plate 3 assembly.One lateral edge portion of described tailgate light fixture 1 is fixedly connected on mounting box lamp installation face 52 and backdoor inner plate 3 by bolt 4.Because the Forming depth of this independently lamp installation box is deep, mounting box face of weld is at close mounting box port edge place, therefore the Pressing Deformation rebound amount of mounting box face of weld 51 is large, if weld part rack of fusion, easily cause the welding region that mounting box face of weld 51 and tailgate outside plate light fixture mate face 21 to produce gap, and then cause welding region to leak and infiltrate between tailgate outside plate and backdoor inner plate.

In addition, owing to adopting this independently lamp installation box structure, tailgate light fixture is positioned on lamp installation box, and the edge of tailgate light fixture will connect with tailgate outside plate and mates, because tailgate light fixture location and coupling are respectively on different parts, the accumulation of tolerance cannot ensure causing the gap offset between tailgate light fixture and tailgate outside plate, and then affects the presentation quality of vehicle body.

Summary of the invention

The object of this invention is to provide a kind of automobile back door lamp-mounting structure, to avoid infiltrating rainwater between tailgate outside plate and backdoor inner plate, improve simultaneously and coordinate outward appearance between tailgate light fixture with tailgate outside plate.

Automobile back door lamp-mounting structure of the present invention, comprise tailgate light fixture, tailgate outside plate and backdoor inner plate, tailgate outside plate and backdoor inner plate fasten, tailgate outside plate is provided with the indent box body that integrated punching is shaping, the shape at indent box body edge is consistent with the marginate shape of tailgate lamp, the side edge of indent box body has tailgate light fixture location and installation plate, at this tailgate light fixture location and installation plate place, one lateral edge portion of tailgate light fixture is fixedly connected with backdoor inner plate with tailgate outside plate by bolt, and the edge of the edge of tailgate light fixture and indent box body is matched.

The lamp installation box of the present invention owing to will weld with tailgate outside plate in existing automobile back door lamp-mounting structure, be improved to the shaping indent box body of integrated punching on tailgate outside plate to hold tailgate light fixture, make to no longer include solder joint between lamp installation box and tailgate outside plate, thus avoid between rainwater infiltration tailgate outside plate and backdoor inner plate; And, because tailgate outside plate and lamp installation box are the same parts combined as a whole, tailgate light fixture location and installation can not make the uneven or gap length in the gap between tailgate light fixture edge and indent box body edge not easily ensure on tailgate outside plate situation because of cumulative limit occurs, thus improves and coordinate outward appearance between automobile back door light fixture with tailgate outside plate.
