Description

Technical Field

[0001] The utility model relates to a hidden electric exterior door handle tolerance adjuster. Background Art

[0002] In the automotive field, tolerance adjusters are used to automatically compensate for the accumulated tolerances between the door handle mounting point and the door sheet metal stamping and welding. If the tolerance adjuster is not used, the gap and surface difference between the handle and the outer sheet metal need to be checked back and forth during installation.

[0003] A Chinese patent application with application number 202310463671.0 discloses a tolerance adjuster, comprising an adjuster body and a base cooperatedly connected to its outer surface, and also comprising a limit ring plate and a mounting screw arranged in the lower end of the adjuster body; the adjuster body is formed by a first semi-cylindrical component and a second semi-cylindrical component being matched and connected, and an intermittent external spiral structure is provided on its outer surface; a transverse hook is provided on both sides of the matching part of the first semi-cylindrical component, and a clamping hole is provided on both sides of the matching part of the second semi-cylindrical component, and the two transverse hooks are respectively connected with the two clamping holes to match and connect the first semi-cylindrical component and the second semi-cylindrical component together; the mounting screw passes through the limit ring plate and extends from the lower end of the adjuster body. A boss is provided in the middle part of the lower part of the limiting ring plate and a circular hole is provided in the center. The circumferential edge of the lower part of the limiting ring plate cooperates with the circular limiting step formed by the first step of the first semi-cylindrical component and the second step of the second semi-cylindrical component. When the screw is tightened, the first semi-cylindrical component and the second semi-cylindrical component are flattened, thereby eliminating the gap between the regulator body and the base.

[0004] The following problems exist during the installation of this type of tolerance adjuster:

[0005] 1. Since the regulator body is a split two-piece structure with low structural rigidity and poor locking firmness, the two components of the body may be forced to be dislocated after its mounting screws are tightened, resulting in the two components of the body being subjected to opposite forces in the Y direction, causing torsion and the regulator being in an unstable state.

[0006] 2. There is a gap between the two pieces of the regulator body. When locked, the two pieces are squeezed against each other in the X / Z direction, resulting in elastic deformation and insufficient positioning reliability.

[0007] 3. The regulator body is divided into two pieces, which will cause the wall thickness of the body to be inconsistent. There will be a height difference when locking, resulting in uneven force, insufficient strength, and insufficient positioning reliability. Utility Model Content

[0008] The utility model provides a hidden electric exterior door handle tolerance adjuster, which has high structural strength, uniform force, firmness, reliability and accurate positioning.

[0009] The cam is an angular channel that is formed on a pair of camming links of different types, and the cam is abutted against the center of the button bars by the spring, and the cam is engaged with the button bars by the spring, so that the cam can be engaged with the button bars by the spring, thereby preventing the cam from engaging with the button bars.

[0010] The tolerance adjuster of the utility model is suitable for the installation of automobile exterior door handles, and the base is a matching part on the door handle mechanism. The tolerance adjuster can bear lateral and vertical forces as a whole, has small elastic deformation, accurate positioning, and is less affected by ambient temperature. The fixing ring is confined between the first elastic clip and the outer protrusion, so that it and the mounting bolt will not separate from the adjuster body. At the same time, the mounting bolt is centered under the retention of the second elastic clip, which can improve the installation accuracy and prevent the mounting bolt from falling out. When the tolerance adjuster of the utility model is assembled with automobile sheet metal, the operation of finding holes and locking the mounting bolts is quick and simple.

[0011] The utility model also has the following preferred designs:

[0012] The lower end of the regulator body of the utility model is provided with a limiting boss to prevent the base from escaping from the lower end of the regulator body.

[0013] The regulator body of the utility model is threadedly connected with the base through a double thread structure, which can reduce the time for installing the tolerance regulator and improve assembly efficiency.

[0014] The regulator body of the utility model is provided with a back-stop structure for engaging with the base, which can prevent the base from falling out. Specifically, a back-stop groove is provided on the regulator body.

[0015] A washer is arranged between the outer protrusion of the mounting bolt and the limiting structure on the regulator body of the utility model.

[0016] Preferably, the gasket is a stepped gasket, a first portion of the stepped gasket is located between the outer protrusion and the upper end surface of the limiting structure, and a second portion of the stepped gasket is located in the through hole of the limiting structure.

[0017] The utility model adds a washer to improve the mechanical bearing capacity of the tolerance adjuster and enhance the product's anti-extrusion ability. When installing the bolt, the torque borne by the bolt will not be directly transmitted to the adjuster body, thereby protecting the adjuster body structure.

[0018] The beneficial effects of the utility model are:

[0019] 1. The regulator body of the tolerance regulator of the utility model is an integrated structure, which can bear the lateral and vertical forces as a whole, has small elastic deformation, accurate positioning, and is less affected by the ambient temperature.

[0020] 2. When the tolerance adjuster of the utility model is assembled with the automobile sheet metal, the operation of finding the hole and locking the mounting bolt is quick and simple, and the fixing ring is restricted between the first elastic clip and the outer protrusion, so that the fixing ring and the mounting bolt will not separate from the adjuster body.

[0021] 3. The second elastic clip provided on the fixing ring of the utility model serves as an elastic retaining structure, which can keep the mounting bolt centered and prevent the mounting bolt from falling out.

[0022] 4. The utility model can also add washers to improve the mechanical bearing capacity of the tolerance adjuster and enhance the product's anti-extrusion ability. When installing the bolts, the torque borne by the bolts will not be directly transmitted to the adjuster body, thereby protecting the adjuster body structure.

[0023] 5. The regulator body of the utility model can reduce the time required for installing the tolerance adjuster and improve assembly efficiency through a double-threaded connection structure.

[0024] 6. The utility model reduces the number of parts, which is beneficial to reducing the manufacturing cost of parts. BRIEF DESCRIPTION OF THE DRAWINGS
