Description

Automobile door external-open handle resilience mechanism

Technical field

The utility model belongs to automobile door opening mechanism, is specifically related to the heavy door external-open handle resilience mechanism of automobile.

Background technology

Door lock is the important body accessories of collection practicality and ornamental and one in the automobile, is the main anti-theft device of automobile.It has when driving that car door is locked to guarantee the function of occupant safety simultaneously.Its outward open handle mainly can be divided into four classes: rotary, lift pull-type, push button and handle type.The mechanical door lock pull-type handles that lift that use wherein more.Lift the lever resilience mechanism that pull-type handle now adopts, its structure as shown in Figure 1, comprise torsion spring mechanism 11, torsion spring 12, reseting movement piece 13, because outward open handle 14 is to fit with the chute 16 of torque spring mechanism by the outstanding moulding on the handle 15 to rotate, chute becomes U type (see figure 2), elastic force by torsion spring guarantees the interlock of handle and torque spring mechanism fully, thus handle in switch door process, slippage from the chute of torque spring mechanism easily; The movement locus of the outstanding moulding of track and handle that rotatablely moves of torque spring mechanism intersects during assembling, and is relatively more difficult when causing the handle assembling.

Summary of the invention

The purpose of this utility model is at the prior art above shortcomings, and a kind of automobile door external-open handle resilience mechanism is provided, and makes its stable performance, and assembly manipulation is convenient, assemble laborsaving firm.

The technical solution of the utility model is as follows:

Automobile door external-open handle resilience mechanism, it mainly comprises: rotating shaft, pivoted arm, spring and handle bracket.The two end supports of rotating shaft is on handle bracket, be rotationally connected with the handle bracket axis hole, pivoted arm is connected with rotating shaft by the stop square hole, and return spring one end is stuck on the pivoted arm, the other end is stuck in pivoted arm is turned round around the shaft, and handle cooperates by a L type barb and pivoted arm face.When drawing back handle, the drive pivoted arm rotates, under the effect of return spring, pivoted arm is subjected to the effect of two power: first power F1 is that around the shaft rotation makes handle draw back the back resilience, second power F2 is that the axial force along rotating shaft makes pivoted arm move toward the direction of applying handle, prevents that handle and pivoted arm from coming off.The support pivoted arm can axially move among a small circle along shaft axis, can prevent that pivoted arm from big moving axially taking place simultaneously under the effect of return spring again.

In addition, this mechanism has also designed a location structure, mainly is to utilize resilience mechanism to realize that the rotary motion trace of support pivoted arm rotary motion trace and outward open handle L type barb is non-intersect along moving among a small circle of axis, so that the assembling of handle is easy.Location structure is mainly realized by the locating lug in corresponding the snapped in locating slot that is provided with on locating slot on the handle bracket and the pivoted arm.Locating piece can snap in locating slot, stops the axially-movable of pivoted arm under the effect of spring.Can locate after so just can making resilience mechanism move on to rigging position, its rebound performance that can satisfy handle is required and not lose efficacy, the difficult assembling in the time of solving the handle assembling again, and requirements such as structure durability is good, rapid operation.

This utility model has following characteristics:

This resilience mechanism structure is simple, and the installation and removal that make handle are comparatively convenient and can satisfy the force request and the performance requirement of resilience mechanism, and the resilience function is unaffected, and rapid operation is easy.
