AI Technical Summary
The existing tolerance adjuster has a large reduction in tightening torque, which causes deviations in the surface difference between the door handle and the outer door panel.
It adopts a combination structure of spiral sleeve, fastener and metal part, in which the metal part protrudes from one end of the spiral sleeve. The fastener transmits axial force through the metal part. The spiral sleeve does not bear the compressive force of the fastener. The high creep resistance of the metal part reduces the amount of fastening torque attenuation.
The residual tightening torque of the tolerance adjuster is improved, preventing deviations in the gap surface difference between the door handle and the outer panel of the door. The structure is simple and the cost is low, with the residual tightening torque reaching more than 80% of the initial pre-tightening torque.

The hidden door handle is usually connected with the outer panel of the vehicle door through a tolerance adjuster to effectively absorb the manufacturing tolerances of the door handle mounting plate and the outer panel of the vehicle door.
[0003] In the prior art, the tolerance adjuster includes a spiral sleeve and a bolt, one end of the spiral sleeve is attached to a fixed plate, and the bolt is locked with the mounting plate after passing through one end of the spiral sleeve.
[0004] Since the spiral sleeve is a plastic part, the plastic part has poor creep resistance, which can cause a large fastening torque decay of the tolerance adjuster, resulting in a low residual fastening torque of the tolerance adjuster, which can cause the gap and surface difference between the door handle and the outer panel of the vehicle door to deviate as the vehicle is used.
