the second setting mode is as follows: the locking sheet 13 and the positioning nut 12 are integrated by injection molding and are fixedly arranged in a groove 121 of the positioning nut 12;

the third setting mode is as follows: the locking piece 13 and the handle base positioning structure 41 are molded into a whole and are fixedly arranged on the bottom end face of the handle base positioning structure 41. The first arrangement is the least expensive; the second and third arrangements reduce the number of installation steps, and the locking tab is not easy to lose, but the investment cost is increased.

The embodiment also provides an installation method of the installation structure of the hidden handle, which comprises the installation of the tolerance adjuster 1 and the hidden handle 4, and the installation of the hidden handle 4 and the inner metal plate 3 and the outer metal plate 5; and the tolerance adjuster 1 and the hidden handle 4 adopt a lateral push-in mounting mode, and the hidden handle 4, the inner metal plate 3 and the outer metal plate 5 adopt a three-point positioning tolerance automatic adjustment mounting mode.

Further, the installation of the tolerance adjuster 1 and the hidden handle 4 comprises the following steps:

step one, after the tolerance regulator 1 is assembled, the elastic sheet regulating nut 11, the positioning nut 12 and the locking sheet 13 are assembled into a complete component, the tolerance regulator 1 is pushed in from an opening of a sliding groove 412 on the side surface of the outer edge of the bottom of the handle base positioning structure 41, after the tolerance regulator 1 slides through a stop clamping foot 413, the stop clamping foot 413 is popped out, and the tolerance regulator 1 is limited in a space formed by the stop column 411, the sliding groove 412 and the stop clamping foot 413 at the bottom of the handle base positioning structure 41;

and step two, referring to the step one, sequentially installing the 3 tolerance adjusters 1 on the 3 handle positioning structures 41 of the hidden handle 4, namely completing the integral installation of the tolerance adjusters 1 and the hidden handle 4. The tolerance regulator 1 is used as a sub-part of the hidden handle 4, and the tolerance regulator 1 is installed on the hidden handle 9 to form a complete part which can enter the installation procedure of the inner metal plate 3, so that the subsequent assembly process of the inner metal plate 3 is ensured to be convenient to install without interference; the hidden handle 9 is installed with 3 tolerance adjusters 1, and the 3 tolerance adjusters 1 can move freely in the limited space at the bottom of the handle holder positioning structure 41, and the moving range is the tolerance adjusting range of the X/Z direction of the plane to be adjusted. The tolerance regulator 1 is installed, namely the locking sheet 13 is placed in the groove 121 of the positioning nut 12, and the spring sheet regulating stud 11 is inserted into the accommodating cavity 122 of the positioning nut 12.

Further, the installation of hiding handle 4 and interior panel beating 3, outer panel beating 5 includes following step:

step one, pushing a movable handle 42 of the hidden handle 4 to sequentially pass through a first slot 32 on an inner metal plate 3 and a second slot 51 on an outer metal plate 5;

secondly, positioning the gap and height between the movable handle 42 and the outer metal plate 5, further restricting the hidden handle 4 and the handle base positioning structure 41 at a fixed position, and positioning the spatial positions of 3 handle

base positioning structures

41 and 3 bolt mounting through holes of the inner metal plate 3; the difference in the positions of the handle base positioning structure 41 and the 3 mounting points of the inner metal plate 3 is the working range of the tolerance regulator 1; the movable handle 42 can be positioned by a tool to determine a gap on the outer metal plate side, or can be positioned by other methods for the movable handle in the outer metal plate direction, and the hidden handle 4 is an assembly whole, so that the relative position of the handle base positioning structure 41 is determined accordingly.

Thirdly, the fastening bolt 21 sequentially penetrates through the fixing gasket 22, the handle base positioning structure 41 and the tolerance regulator 1, after the fastening bolt 21 reaches the elastic sheet 111 of the elastic sheet regulating stud 11, the fastening bolt 21 which rotates forwards is tightly held by the elastic sheet 111, the friction force of the tightly held fastening bolt 21 generates friction torque to drive the elastic sheet regulating stud 11 to rotate, the elastic sheet regulating stud 11 rotates and then rises, the fourth regulating gap 9 is continuously reduced, and after the end surface of the first boss 113 of the elastic sheet regulating stud 11 is contacted with the plane of the inner metal plate 3, the elastic sheet regulating stud 11 stops moving forwards to complete tolerance regulation in the axial Y direction; after the first boss 113 contacts the inner metal plate 3 and is blocked, the fastening bolt 21 passes through the elastic sheet 111 to continue to advance, a bolt mounting through hole of the inner metal plate 3 is found and passes through the through hole to enter a screw hole of the fixing nut 31, and in the process of entering the fixing nut 31, the fastening bolt 21 drives the fixing gasket 22 and the tolerance regulator 1 to move to the position in the same axial direction with the fixing nut 31, so that tolerance regulation in X/Z2 directions of a plane is completed; the rotating fastening bolt 21 continues to advance and is locked with the fixing nut 31, and the hidden handle 4 can be fixedly installed on the inner metal plate 3 after being locked;

and step four, referring to the three steps, sequentially locking the 3 fixing nuts 31 on the inner metal plate 3, namely completing the installation of the whole hidden handle 4, the inner metal plate 3 and the outer metal plate 5.

The movable handle 42 of the hidden handle 4 is embedded in the second slot 51, and a gap is arranged between the periphery of the movable handle 42 and the outer metal plate 5, the gap needs to be uniform and symmetrical, and the outer end surface of the movable handle 42 of the hidden handle 4 is flush with the outer end surface of the outer metal plate 5, so that the hidden handle is more attractive; the first slot 32 is to ensure that the movable handle 42 of the hidden handle 4 and other structures to be arranged can pass through, cannot interfere and obstruct the installation action of the hidden handle 4, and keeps reasonable clearance to increase the strength of the sheet metal.

The working principle of the invention is as follows:

the working principle is as follows: the arrangement of the first adjusting gap 6 and the second adjusting gap 7 enables the hidden handle 4 to be positioned by an external tool, when the fastening bolt 21 aligns the inner metal plate 3 and the fixing nut 31, the fixing gasket 22, the locking sheet 13 and the thread group assembly can move freely, the mounting position can be found without external force on the fastening bolt 21, automatic adjustment of zero external force XZ to tolerance is achieved, and mounting work is more convenient and smoother;

the third adjusting gap 8 and the fourth adjusting gap 9 are arranged so that in the screwing process of the fastening bolt 21, the elastic sheet adjusting stud 11 is driven by the fastening bolt 21 to rotate by the holding friction force of the elastic sheet 111 to form height change and realize automatic adjustment of Y-direction tolerance;

the fastening bolt 21 finally realizes locking and fixing after X/Y/Z position adjustment through the locking fixing gasket 22, the handle base positioning structure 41, the locking sheet 13, the positioning nut 12, the elastic sheet adjusting stud 11 and the fixing nut 31.
