Detailed description of the invention
Below in conjunction with specific embodiments and accompanying drawing, the utility model is further described in detail.It is intended to elaborate specific embodiments of the present utility model, the utility model is not produced to any restriction, and protection domain of the present utility model is as the criterion with claims.
With reference to Fig. 2, show a kind of automobile tail light of the present utility model, comprise a lamp housing 1, a locate lamp area bolt 2, described locate lamp area bolt 2 upper ends are connected with lamp housing 1 integrated injection molding, and described locate lamp area bolt 2 lower ends are plugged in a seal cap 7, described locate lamp area bolt 2 is inserted 7 by seal cap and is connected on vehicle body 3, described seal cap 7 is divided into be in contact with one another two-layer, this two-layer plastic layer 5 and rubber layer 6 of being respectively, wherein, plastic layer 5 contacts locate lamp area bolt 2, and rubber layer 6 contacts vehicle body 3.Because seal cap 7 is composited by inner plastic layer 5 and outside rubber layer 6, making seal cap 7 inside have rigidity can combine closely with locate lamp area bolt 2, outside rubber layer 6 has certain rigidity due to what the enhancing of plastic layer 5 also became, not yielding.Thereby location and the sealing problem taken into account between lamp housing 1 and vehicle body 3 are solved.
Below in conjunction with Fig. 3, describe the detailed structure of the seal cap 7 of the utility model automobile tail light in detail.Automobile tail light of the present utility model shown in it adopt plastic injection-moulded one-tenth one substantial cylindrical of high-modulus the plastic-substrates part 18 of upper end open, and the edge of these plastic-substrates part 18 upper end open extends to form an anchor ring 8 to surrounding, this upper end open extends to form a chamber 17 downwards, the chamber wall of described chamber 17 forms four sections from top to bottom successively, be respectively the first plastics sections 9, the second plastics sections 10, the 3rd plastics sections 11, the 4th plastics sections 12, described the first plastics sections 9 is outward-dipping with respect to the axis of chamber 17 from the bottom to top, the axis that described the first plastics sections 9 upper end edges are parallel to chamber 17 upwards extends to form the second plastics sections 10, the upper end of described the second plastics sections 10 upwards extends to form the 3rd plastics sections 11 along the direction that slopes inwardly with respect to the axis of chamber 17, the upper end of described the 3rd plastics sections 11 is upwards along extending into the 4th plastics sections 12 with respect to the outward-dipping direction of axis of chamber 17, the height of four sections that this chamber 17 forms is from top to bottom identical, and the first plastics sections 9, the second plastics sections 10, the 3rd plastics sections 11 is identical with the angle of the angle of the axis of chamber 17, those of ordinary skill in the art are clear, this chamber 17 just coordinates and holds locate lamp area bolt 2 use, all other simple variant that meet this thought play the effect of fixing locate lamp area bolt 2 and sealing car light, so all should belong in protection domain of the present utility model.
Described plastic-substrates part 18 outside faces form the rubber layer 6 of a low modulus by quadric injection mould.The chamber portion of described rubber layer 6 coating plastic base parts 18 is divided into four sections from bottom to top, be respectively the first rubber sections 13, the second rubber sections 14, the 3rd rubber sections 15, the 4th rubber sections 16, the first rubber sections 13 is outward-dipping with respect to the axis of chamber 17 from the bottom to top, the first rubber sections 13 upper ends upwards extend into the second rubber sections 14 along the axis direction that is parallel to chamber 17, the second rubber sections 14 upper ends are upwards along extending into the 3rd rubber sections 15 with respect to the outward-dipping direction of axis of chamber 17, the 3rd rubber sections 15 upper ends extend to after crossing with the extended line of the second rubber sections 14 and extend to straight up the 4th rubber sections 16 near chamber 17 directions along level, described the first rubber sections 13, the second rubber sections 14, the 3rd rubber sections 15, the 4th rubber sections 16 is contacted with respectively described the first plastics sections 9, the second plastics sections 10, the 3rd plastics sections 11, the 4th plastics sections 12.The height of described the 4th rubber sections 16 is identical with automobile case thickness.And described the first rubber sections 13, the first plastics sections 9 are identical with the angle of described chamber 17 axis respectively, and described the first rubber sections 13 is identical with the length of described the first plastics sections 9; Described the second rubber sections is identical with the length of described the second plastics sections, because described seal cap 7 is divided into the plastic layer 5 and the rubber layer 6 that are in contact with one another, this is two-layer forms by quadric injection mould means, plastic layer 5 contacts locate lamp area bolt 2, rubber layer 6 contacts vehicle body 3, and owing to having used the sealing of two-layer compound, 7 make sealing cap 7 inside have the rigidity of plastics, play locate lamp area bolt 2 and combined closely with vehicle body 3, be difficult for the positioning action in use coming off; Make again sealing cap 7 outsides there is the leak tightness of rubber, play the sealing function of vehicle body 3 and car light.Because the hierarchy of plastic layer 5 and rubber layer 6 also makes plastic layer 5 more firm with the combination of rubber layer 6.This rubber layer 6 just coordinates being tightly connected of vehicle body 3 and automobile tail light seal cap 7, plays the effect of fixing locate lamp area bolt 2 and sealing car light, so all other simple variant that meet this thought all should belong in protection domain of the present utility model.
These automobile tail light seal cap 7 diameters are 16-20mm, and sealing cap height is 10-20mm, and these plastic-substrates part 18 wall thickness are 1-2mm, and these rubber layer 6 wall thickness are 1-3mm.In the present embodiment, sealing cap 7 diameters are 17mm, and the height of described seal cap 7 is 17mm, and described plastic-substrates part 18 wall thickness are 1mm, and the wall thickness of first, second rubber sections of described rubber layer 6 is 1mm, and the wall thickness of described the 3rd rubber sections is 3mm.Those of ordinary skill in the art are clear, and those of ordinary skill in the art are clear, and this size is only for coordinating the leak tightness of locate lamp area bolt 2 and automobile tail light seal cap 7, not as limit.
This high-modulus plastic can be selected from PA, PBT, PET, POM, PPO etc.; This low modulus rubber can be selected from NBR, EPDM, PU etc.
When use, by top layer injection moulding the seal cap 7 of rubber layer 6 be fixed on vehicle body 3 by pressing, because the height of the 4th rubber sections 16 in the rubber layer 6 on seal cap 7 top layers is identical with the thickness of vehicle body 3 shells, therefore steam packing sealing cap 7 and the problem that has ensured leak tightness being connected of vehicle body 3.Locate lamp area bolt 2 and lamp housing 1 integrated injection molding, when lamp housing 1 is installed on vehicle body 3, locate lamp area bolt 2 contacts with seal cap 7, lamp housing 1 is produced to the effect of location, this kind of mounting structure do not need accessory appliances to install, there is easy installation and removal feature efficiently, and ensured the leak tightness of car light and stablizing of car light.
Above-described embodiment is only for illustration of the utility model; and be not to restriction of the present utility model; the those of ordinary skill in relevant technologies field; in the situation that not departing from the utility model scope; can also make various variations and modification; therefore all technical schemes that are equal to also should belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
