A tolerance adjusting device and an installation structure for concealing a door handle

Abstract

The invention discloses a tolerance adjustment device and an installation structure for concealing a door handle. The tolerance adjustment device comprises a stud, a fixing bracket and a locking assembly; the outer wall of the stud is provided with a first thread and a flange surface; The flange surface is an annular structure surrounding the stud, and there is a preset distance between the flange surface and the end surface of the stud, and the flange surface is used to abut the stud for positioning The fixing bracket is provided with a first through hole, and the inner wall of the first through hole is provided with a second thread; the stud and the fixing bracket pass through the first thread and the second thread. Two threaded connections; the locking assembly is used for fixing the stud and the fixing bracket to the mounting surface. The tolerance adjustment device and the installation structure of the hidden door handle of the present invention can effectively solve the problem of preventing the tolerance adjuster from rotating in the prior art, improve the positioning accuracy, and effectively improve the qualified rate of one-time assembly of the hidden door handle.

Description

technical field [0001] The invention relates to the field of automobile parts manufacturing, in particular to a tolerance adjustment device and an installation structure for concealing a door handle. Background technique [0002] With the development trend of lightweight automobiles, the application of closed-section or non-closed-section thin-walled profiles in automobile and other manufacturing industries is increasing. It is mainly used to fix other components. There are generally holes on the wall plate parts. When installing other parts, connect bolts or rivets and other connecting parts through the parts to be installed and the holes of the two thin-walled plate parts, and use nuts to tighten or rivet rivets. The components to be installed are fastened to the thin-walled profile. Since the wall thickness of the thin-walled plates is generally thin, it is easy to squeeze the two thin-walled plates after tightening the bolts or riveting the rivets, causing the two thin-...

Problems solved by technology

[0003] When the tolerance absorber in the prior art is used, it is fixed and clamped on the thin-walled plate through the claws at the lower part of the nut sleeve. However, the deformability of the claws of this structure is poor, so it consumes a lot of effort when clamping. , cannot be snapped into place at one time, and it is easy to cause damage to the claws or thin-walled panels, and the claw structure of this structure is relatively complicated, and the injection molding process is difficult, which increases the manufacturing cost

[0004] The car door includes the outer sheet metal of the car door and the inner sheet metal of the car door. The existing conventional door handle is divided into an outer handle and an inner handle structure. The inner and outer handles are separated by the outer sheet metal of the car door, so that the handle has more fixing points ;The hidden door handle is slotted on the outer sheet metal of the car door as a whole, and the hidden handle is embedded in the outer sheet metal as a whole. Since the hidden door handle needs to complete the function of turning and opening the door, it is usually installed on the car door through a base with a tolerance absorber Yes, due to the defects of the tolerance absorber in the prior art mentioned above, in practical applications, it is difficult to control the flatness of the outer surface of the hidden door handle and the surface of the door panel, which often causes the outer surface of the hidden door handle to cooperate with the surface of the door panel Unsmoothness and mounting screws drive the door handle base to protrude and deform the door panel, which seriously affects the appearance of the vehicle
