Detailed description of the invention
The present invention is further described below in conjunction with specific embodiment and accompanying drawing.
A kind of automobile back door snap close mounting structure as described in Fig. 1-6, it comprises the threshold portion 1 being in automobile rear floor back segment and the rear door lock reinforcement 9 fitted tightly in this threshold portion 1 lower end, have in threshold portion 1 centre position can locate lift tailgate snap close 12 lift tailgate locating location hole 6, this lifts tailgate locating location hole 6 and runs through the tailgate door bolt nutplate 7 of rear door lock reinforcement 9 and this rear door lock reinforcement 9 lower end locating; The threshold portion 1 of lifting both sides, tailgate locating location hole 6 has lock pin locating hole 31 respectively under the clamshell doors can locating lock pin 4 under clamshell doors, and under this clamshell doors, lock pin locating hole 31 runs through the tailgate locking nut plate 10 that rear door lock reinforcement 9 and this rear door lock reinforcement 9 lower end are located.
The present invention is when snap close mounting points position and structure do not change, and the threshold portion 1 for automobile rear floor back segment is carried out design and improved.According to the characteristic of lifting tailgate and clamshell doors, to lift tailgate snap close 12 is installed in the middle part of threshold portion 1, lock pin under clamshell doors 4 is installed on the both sides in threshold portion 1 centre position, namely the both sides of tailgate snap close 12 position are lifted, accordingly, installing this structure of lifting lock pin 4 under tailgate snap close 12, clamshell doors can be non-interference, and it also by lifting tailgate threshold backplate 11 or clamshell doors threshold backplate 2 is covered the locating hole not needing to use, ensures the appearance design of whole car body.
Concrete as Fig. 4-6, tailgate door bolt nutplate 7 is positioned rear door lock reinforcement 9 lower end by tailgate door bolt nutplate fixed head 8, this tailgate door bolt straight centre, nutplate fixed head 8 two ends structure in the form of slot, tailgate door bolt nutplate 7 is limited in this channel-shaped structure, and the nutplate fixed head 8 two ends welding of this tailgate door bolt is positioned on rear door lock reinforcement 9 lower surface.And narrow two ends are wide in the middle of tailgate door bolt nutplate 7, lift tailgate locating location hole 6 through on this tailgate door bolt nutplate 7 two ends, and be provided with and the strengthening stud lifting the concentricity axis in tailgate locating location hole 6 in this tailgate door bolt nutplate 7 lower end.
Coordinating between part narrow in the middle of nutplate 7 is fastened with a bolt or latch with tailgate by the channel-shaped structure in the middle of tailgate door bolt nutplate fixed head 8, make tailgate fasten nutplate 7 with a bolt or latch and can fasten a formation adjustable scope of activities in nutplate fixed head 8 with a bolt or latch in tailgate, to ensure to avoid occurring because of error filling the situation unmatched when installing and lifting tailgate snap close 12.The effect of strengthening stud is the local strength increasing the structural strength of tailgate door bolt nutplate 7 self, bonding strength when being connected with bolt thread and this hole site.In addition, be equipped with lock hole in the centre of tailgate door bolt nutplate 7 and tailgate door bolt nutplate fixed head 8, for fastening the fastening location of nutplate 7 after lifting tailgate snap close 12 and having assembled with a bolt or latch to tailgate, ensure that whole snap close is installed stable, firm.
As in Fig. 1-3, tailgate locking nut plate 10 is positioned on rear door lock reinforcement 9 lower surface by a solder joint welding, is provided with the strengthening stud with the concentricity axis of lock pin locating hole 31 under clamshell doors in tailgate locking nut plate 10 lower end.Same, by a welding location, make tailgate locking nut plate 10 form an adjustable scope of activities in rear door lock reinforcement 9 lower end, to ensure to avoid occurring because of error filling the situation unmatched when installing lock pin 4 under clamshell doors.The effect of strengthening stud is the local strength increasing the structural strength of tailgate locking nut plate 10 self, bonding strength when being connected with bolt thread and this hole site.
In this example, tailgate door bolt nutplate 7, on tailgate locking nut plate 10 corresponding run through lift tailgate locating location hole 6, clamshell doors under lock pin locating hole 31 be two, under cost effectively controls, in case of exceptional circumstances or mounting structure requirement of strength is higher time suitably can increase the quantity of each locating hole.In order to ensure positioning requirements and car load appearance requirement, threshold portion 1, rear door lock reinforcement 9 bottom being equipped with the tailgate of to fasten nutplate 7, tailgate locking nut plate 10 with a bolt or latch with tailgate corresponding and fastening nutplate concave station portion 5, tailgate locking nut plate concave station portion 3 with a bolt or latch.
Finally, threshold portion 1 and rear door lock reinforcement 9 are fitted to weld by multiple solder joint and are connected, and make it fit tightly, and strengthen the mounting points intensity of tailgate snap close.
During assembling, in threshold portion 1 by screw thread run through lift tailgate locating location hole 6 location lift tailgate snap close 12, this threshold portion 1 upper end is established and is lifted tailgate threshold backplate 11 with what lift rear door lock padlock hole 111, namely forming the installation to lifting tailgate snap close 12, can complete and lift tailgate structure; And threshold portion 1 runs through lock pin locating hole 31 under clamshell doors by screw thread locate lock pin 4 under clamshell doors, this threshold portion upper end is with the clamshell doors threshold backplate 2 of lock pin lockhole 21 under clamshell doors, namely form the installation to lock pin under clamshell doors 4, can door structure be completed.In installation process, lift tailgate threshold backplate 11, clamshell doors threshold backplate 2 after completing respective main purpose, also may correspond to lock pin locating hole 31 under clamshell doors, lift tailgate locating location hole 6 and effectively hide, ensure the clean appearance of whole body construction, very practical.
Above the technical scheme that the embodiment of the present invention provides is described in detail, apply specific case herein to set forth the principle of the embodiment of the present invention and embodiment, the explanation of above embodiment is only applicable to the principle helping to understand the embodiment of the present invention; Meanwhile, for one of ordinary skill in the art, according to the embodiment of the present invention, detailed description of the invention and range of application all will change, and in sum, this description should not be construed as limitation of the present invention.
