Description

A kind of assembly that prevents that automobile C post from leaking

Technical field

The utility model relates to a kind of automobile back door guide groove C column assembly, specifically a kind of assembly that prevents that automobile back door guide groove C post from leaking.

Background technology

Respectively there are three columns general motorcar body both sides, are followed successively by front pillar (A post), center pillar (B post), rear pillar (C post) from front to back.Wherein " A " post is exactly the batter post on front windshield both sides; " B " post is exactly the perpendicular fine strain of millet (post) in the middle of the front and back door; " C " post is exactly the adjacent back door of an automobile side column backward; For car, column also plays the effect of doorframe except supporting role.And C post and A post, B post different a bit be exactly not exist sight line to block and problem such as the obstacle of getting on or off the bus, so construction size is also harmless greatly a bit, key is that the leak tightness of C post and vehicle body wants reliable.In the prior art for the moulding of body side wall non-integral and behind the C post, also be provided with the automobile of back door quarter window, frame and being connected of C post after-frame are to connect as one by sulfidization molding technology between the end face of end face by frame before the C post and C post after-frame before its C post, the centre is played and has been complemented each other to form a cavity that inserts for the C post between the end face of the end face of frame before bonded assembly sulfuration part and the C post and C post after-frame, the centre is played on the bonded assembly sulfuration part and is also formed holding tank, is connected with the holding tank of frame before the C post and the holding tank on the C post after-frame and communicates.Frame and C post after-frame are behind the over cure global formation before the C post, send into the assembling of carrying out the C post on the car load factory manufacturing line, after the C post inserts cavity, finished final assembling between frame, C post after-frame and the C post three before the C post, after the three of assembling one installs to car load, only be the relation of inserting between the cavity that frame, C post after-frame form before C post on the car load and the C post.Though the lip limit of the C post in the insertion cavity near the C post before the end face setting of frame, but because back door guide groove C post is a stand-alone product, only insert during assembling in the cavity not do not carry out with each contact surface of cavity that entity is connected and also the cross section on the lip limit of C post for being similar to the U type, when the opening portion of U type contacts with frame end face before the C post, thereby owing to be connected the formation slit with the preceding frame end face incorporeity of C post in the opening portion of U type, in addition, the intersection location place, lip limit of frame before the lip limit of C post and C post, the two intersection, lip limit is misfitted and is not sternly had the slit with glass gluing, therefore, when rainy day or high Pressure-washing apparatus, often occur drainage easily, the car load sealing property is impacted at this two place.The C post is a stand-alone product in addition, and supply of material back is inserted assembling separately by the workman of car load factory, and such fit has increased workman's work capacity widely.

The utility model content

For this reason, technical problem to be solved in the utility model is that the assembling of back door of the prior art guide groove C post and guide groove fore-set can't reach seamless combination and the seepy question that exists, provide frame before a kind of C post, back door quarter window and back door guide groove C post sulfidization molding be one can prevent the assembly that back door guide groove C post leaks.

For solving the problems of the technologies described above, a kind of assembly that prevents that automobile C post from leaking of the present utility model, comprise frame before the C post that is arranged on the car roof left and right sides, be arranged on the quarter light glass of back door with described C post before the C post after-frame that intersects of frame, and before the described C post frame and the C post after-frame intersection C post that side bar extends under automobile, it is characterized in that: before described C post between frame, described C post after-frame and described C post three's the end face infall sulfidization molding one joint with described C post before frame, described C post after-frame and described C post moulding one.

Above-mentioned prevent the assembly that automobile C post leaks, described joint with described C post before form on the frame bonded assembly end face one with the C post before frame lip side post before the bonded assembly C post of frame lip limit, with form on the described C post bonded assembly end face one with described C post lip limit bonded assembly C post lip side post, described joint before described C post, also form between frame lip side post and the described C post lip side post one section transition cambered surface with described C post before frame lip side post and described C post lip side post be connected.

Above-mentioned prevent the assembly that automobile C post leaks, also form the joint holding tank on the described joint, frame holding tank and described C post after-frame holding tank are communicated with before described joint holding tank and the described C post.

Technique scheme of the present utility model has the following advantages compared to existing technology, 1, the utility model is frame before the C post, between C post after-frame and C post three's the end face infall sulfidization molding one joint with the C post before frame, C post after-frame and C post moulding one, shaping integrated assembly is delivered to and is directly carried out the car load assembling on the manufacturing line, the assembly error that causes owing to artificial assembling C post and the work capacity of assembling have so not only been reduced, can make simultaneously the preceding frame of C post, exist good entity to connect between C post after-frame and the C post, can reach and prevent the purpose of leaking between the frame and C post before the C post; 2, frame lip side post before the C post on the joint of the present utility model, C post lip side post and with the setting of frame lip side post before the C post and C post lip side post bonded assembly transition cambered surface, can with frame lip limit before C post lip limit and the C post well transition be connected, not only can eliminate when directly intersect on frame lip limit before C post lip limit and the C post because of cross surface mutually misfits and have the slit, and the setting of transition cambered surface avoided frame end face direct contact causes before C post lip limit and the C post contact surface to misfit and the slit that produces, thereby reached good waterproof effect; 3, also form the joint holding tank on the joint, be arranged so that before the C post frame holding tank and the C post after-frame holding tank of joint holding tank interconnect, and are convenient to like this before the C post on frame and the C post after-frame other parts to be installed.
