Description

Technical Field

[0001] The utility model relates to the technical field of tolerance adjustment connectors, in particular to a bolt centering tolerance adjuster. Background Art

[0002] With the development of society and the improvement of people's living standards, electric vehicles have become an indispensable means of transportation for people's daily travel, and hidden handles are a characteristic product of electric vehicle intelligence.

[0003] Currently, hidden handles on cars are installed on the outer door sheet metal through tolerance adjusters. The existing adjusters include a sleeve, studs, bolts and end caps. The bolts have a large amount of movement inside, especially when the head is lowered, which makes it difficult for the bolts to find the center hole of the nut during installation. At the same time, the sleeve causes the adjuster to be large in size, and the installation strength with the handle base is low, which increases the installation risk.

[0004] Therefore, how to design a bolt centering tolerance adjuster that is simple in structure, easy to operate, accurate in hole finding, and not easy to fall out is a problem that technical personnel in this field urgently need to solve. Utility Model Content

[0005] The utility model provides a bolt centering tolerance adjuster, which solves the technical problems of the existing adjuster in that the bolt has a large amount of movement, is difficult to find a hole and is easy to come out.

[0006] The utility model solves the above technical problems with the following technical solutions: a bolt centering tolerance adjuster, comprising: a hollow stud, a connecting tube and a bolt,

[0007] The hollow stud is threadedly connected to the threaded hole of the handle base and a limiting ring is fixed on the inner wall of its lower end; the connecting tube is inserted into the hollow stud and at least three elastic clips are fixed on the inner wall of its lower end, and the at least three elastic clips are symmetrically distributed around the origin of the connecting tube and define a deformation area between them; a flange is fixed on the screw rod of the bolt near its nut end, the screw rod of the bolt is inserted into the deformation area and its nut end is in contact with at least three elastic clips respectively, and the bottom end of the flange presses on the top end of the limiting ring.

[0008] The beneficial effects of the present invention are as follows: the hollow stud is first threadedly connected to the threaded hole of the handle base, and then at least three elastic clips are used to form a deformation area in the connecting tube. Since the connecting tube is inserted into the hollow stud and the bolt is inserted into the deformation area, the movement of the bolt can be reduced after the bolt is drooped, thereby improving the accuracy and convenience of bolt hole finding.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Further, the deformation region is circular or quadrilateral.

[0011] Further, it further includes an upper limit bump and a lower limit bump. A hanging groove is provided at the top edge of the hollow stud, and the hanging groove penetrates the inner side wall and the outer side wall of the hollow stud; the upper limit bump is fixed on the outer side wall of the connecting cylinder and can be adaptively inserted into the hanging groove to limit the further upward movement of the handle base; the lower limit bump is fixed in the gap between the corresponding teeth at the bottom end of the bolt to limit the further downward movement of the handle base.

[0012] The beneficial effect of the above further measure is: First, fix the upper limit bump on the outer side wall of the connecting cylinder and insert it into the hanging groove, which can limit the further upward movement of the handle base; then fix the lower limit bump in the gap between the corresponding teeth at the bottom end of the bolt, which can limit the further downward movement of the handle base.

[0013] Further, it further includes a positioning strip. A positioning groove is provided on the inner side wall of the hollow stud along its axial direction; the positioning strip is fixed on the outer side wall of the connecting cylinder along the axial direction of the connecting cylinder and is slidably inserted into the positioning groove.

[0014] The beneficial effect of the above further measure is: By inserting the positioning strip into the positioning groove, since the positioning strip is fixed on the outer side wall of the hollow stud and the positioning groove is provided on the inner side wall of the hollow stud, the connecting cylinder can be positioned and inserted into the hollow stud to prevent the connecting cylinder from rotating.
