Abstract

The utility model is utilized for protecting a connecting structure of an automobile car door block hook and a supporting stand, comprising a supporting stand, a hook and rivets for connecting the supporting stand and the hook. A steel jacket is interference built-in a hole at the end portion of the hook, the rivets rivet-connect the supporting stand and the hook through threading rivet connection holes at two feet of the supporting stand and the steel jacket in the hole at the end portion of the hook, and the steel jacket is transition-engaged with the rivets. In addition, when the steel jacket is built-in a hook hole, the steel jacket is made to step shape and ensured with a certain taper in order to ensure symmetry of the built-in positions. The utility model greatly increases connecting contact face of the hook and the rivets through increasing connecting modes of the steel jacket parts, effectively controls shaking of the hook, and reduces strange noise during moving.

Description

An automobile door stopper hook and a frame connecting structure

Technical field

The utility model relates to the caging system of arrangements for automotive doors.

Background technology

Car door limiter is the main component part of car door caging system, and it can limit the open angle of car door, make simultaneously car door regulation stay on the angle of slope from do not open, not self-closing.Stop normally by the main body combination, form by hook 1 and support 2 three parts.Usually hook 1 all is hinged with rivet 3 with the connected mode of support 2, as shown in Figure 1.Such connected mode is because the arm of hook is thick relatively narrow, and hook is being easy to generate in rivet and the rocking of rivet axis vertical line.In the start process, can produce different sound.Be head it off, common way is control rivet axle center and bracket holes axle center, the three-way concentric requirement in hook hole axle center, guarantees the quality of fit of hook hole and rivet shaft.This way has increased the processing technology requirement of single part, is unfavorable for the assurance of procedure quality.

Summary of the invention

The purpose of this utility model is the shortcoming at the prior art existence, proposes a kind of automobile door stopper support and hook syndeton, the articulated manner of appropriate design hook and support, and the increase contact area reduces the gap.

The technical solution of the utility model is as follows:

An automobile door stopper hook and a frame connecting structure, it includes support, hook and is connected their rivet, interference embeds in the end hole of hook a steel bushing, rivet passes the riveted holes of support bipod and the steel bushing in the hook end hole, with support and hook riveted joint, between steel bushing and the rivet interference fits.

In addition, when steel bushing embedded hook hole, in order to guarantee the symmetry of embedded location, steel bushing was made step-like and is guaranteed certain tapering.

The utility model makes its hook increase greatly with the contact surface that is connected of rivet through increasing the connected mode of steel bushing part, and has controlled the rolling momentum of hook effectively, and the different sound that reduces in the start process takes place.

The specific embodiment

Referring to Fig. 4, this syndeton includes support 2, hook 1 and rivet 3 that is connected them and steel bushing 4, steel bushing 4 interference are embedded in the end hole of hook 1, rivet 3 passes the riveted holes of support 2 bipods and the steel bushing 4 in the hook end hole, with support 2 and hook 1 riveted joint, be interference fits between steel bushing 4 and the rivet 3.Referring to Fig. 3, steel bushing 4 external surfaces are step-like A, and embedded part has tapering B.

Referring to Fig. 2, during assembling, earlier steel bushing 4 interference are embedded the end hole of hook 1, the operation of holing then, ream, dummy rivet 3 is pressed into support 2 and carries out riveted.

Claims

1, an automobile door stopper hook and a frame connecting structure, it includes support, hook and is connected their rivet, it is characterized in that: interference embeds in the end hole of hook a steel bushing, rivet passes the riveted holes of support bipod and the steel bushing in the hook end hole, with support and hook riveted joint, between steel bushing and the rivet interference fits.

2, an automobile door stopper hook according to claim 1 and a frame connecting structure, it is characterized in that: the steel bushing external surface is step-like, and embedded part has tapering.
