The specific embodiment

See also Figure 1 and Figure 2, find out that by knowing in figure automobile back door lockset of the present invention has the moving device 1 of lock, and the moving device 1 of this lock is provided with pedestal 11, buckle spare 12, lock plate 13 and jam plate relay 14, wherein:

These pedestal 11 1 sides are concaved with short slot 111, and pedestal 11 is provided with the through hole 112 that is communicated with pedestal 11 upper and lower surfaces in short slot 111 1 sides, and be provided with connecting rod 113 in through hole 112, and connecting rod 113 two ends are the upper and lower surface of exposing pedestal 11, and connecting rod 113 outsides are because of being provided with elastic parts 114 in through hole 112, and make elastic parts 114 1 ends be fixed in the inwall of through hole 112.

This buckle spare 12 is hubbed at pedestal 11 bottom surfaces away from the opposite side of through hole 112, and buckle spare 12 outer rims are concaved with locating slot 121, and is provided with support division 122 on locating slot 121 1 sidewalls.

This lock plate 13 is connected in connecting rod 113 in the side of pedestal 11 soffits, and one side is provided with stopper section 131 to lock plate 13 in the junction, and 131 1 side ends are provided with stop surface 132 in the stopper section, and the other end that aforementioned elastic parts 114 is fixed in through hole 112 is held in lock plate 13.

This jam plate relay 14 is connected in connecting rod 113 in the side of pedestal 11 upper surfaces, so that jam plate relay 14 relies on connecting rod 113 to form the interlock state with lock plate 13, and can be respectively at the upper and lower surface of pedestal 11 pivotable simultaneously, and jam plate relay 14 one lateral buckling has pushing part 141 in the junction.

See also Fig. 3 and shown in Figure 4, find out that by knowing in figure automobile back door lockset of the present invention has relay gear 2, and relay gear 2 is provided with release relay 21 and press part 22, wherein:

This release relay 21 is arranged at the upper side of pedestal 11, and release relay 21 1 ends are provided with driving rod 211, and is arranged with torsion spring 212 on driving rod 211, and torsion spring 212 1 ends are for being held in release relay 21.

This press part 22 is articulated in the outer rim of aforementioned driving rod 211, one side is provided with pressure section 221 and press part 22 is in the articulated section, and pressure section 221 is near pushing part 141, and be provided with pushing part 222 in the opposite side of pressure section 221, and pushing part 222 is bent with promotion face 2221, and this pressure section 211 to the arm of force of press part 12 articulated sections less than the arm of force of pushing part 212 to press part 12 articulated sections, and the other end that makes torsion spring 212 be held in release relay 21 is held in press part 22.

see also Fig. 5 to shown in Figure 7, find out by knowing in figure, as the present invention when using, it is installed in tailgate 31 lower side of vehicle 3, and allow the promotion face 2221 of press part 22 be right against the set open-work 311 of tailgate 31 inner surfaces, and when the tailgate 31 of vehicle 3 is closed condition, the reference column 32 of this vehicle 3 can be positioned at the short slot 111 of pedestal 1, and the locating slot 121 of buckle spare 12 can be placed in reference column 32 outer rims, and the stopper section 131 of lock plate 13 is held in the support division 122 of locating slot 121 1 sides, so that buckle spare 12 can't turn, allow in the firm short slot that is positioned pedestal 11 111 of reference column 32, tailgate 31 can't be opened.

see also Fig. 6, Fig. 8 is to shown in Figure 10, when the user wants to open tailgate 31 by tailgate 31 is inboard, it is first promotion face 2221 by the interior promotion press part 22 of open-work 311, so that press part 22 produces pivotable, and when press part 22 pivotable, this pressure section 221 can promote the pushing part 141 of jam plate relay 14, make jam plate relay 14 produce pivotable according to connecting rod 113, due to pressure section 221 to the arm of force of driving rod 211 less than the arm of force of pushing part 222 to driving rod 211, and pushing part 222 bends out promotion face 2221, therefore the user can rely on promotion press part 22 pivotables easily, and allow press part 22 promote jam plate relay 14 pivotables, and when jam plate relay 14 pivotable, this connecting rod 113 can drive lock plate 13 pivotables simultaneously, so that the stopper section 131 of lock plate 13 breaks away from the support division 122 of buckle spare 12, and allow the stroke of buckle spare 12 be state that can free pivotable, at this moment, the user can push tailgate 31 open, tailgate 31 is opened, and in tailgate 31 in opening process, because the present invention is installed in tailgate 31, therefore the present invention opens displacement for meeting with tailgate 31, move past in journey and buckle spare 12 is in place, can be subject to supporting and pivotable of reference column 32, make the opening direction of locating slot 121 towards the opening direction of short slot 111, and disengaging reference column 32, tailgate 31 can be opened smoothly.

Above explanation is just illustrative for the purpose of the present invention; and nonrestrictive, those of ordinary skills understand, in the situation that do not break away from the spirit and scope that claim limits; can make many modifications, variation or equivalence, but within all will falling into protection scope of the present invention.
