Abstract

The utility model relates to a sedan inner door handle including a base, wherein, a knob is arranged in the base, a pin is connected with the knob, a spline is connected between the knob and the pin for force transmission, and a torsion spring is sleeved on the pin. The sedan inner door handle is characterized in that the knob includes an L-shaped handle and a connecting part positioned below the handle; a spline slot matched with the spline is arranged on the connecting part, and a plurality of I-shaped small slots are formed at the location of the joint between the connecting part and the handle for increasing structural strength; the handle is transmitted to the connecting part in a manner that an arc is formed in the length direction of the handle between the handle and the connecting part thereunder, and a triangular slot is formed in the arc; the spline is a triangular spline which is connected with the pin into an integration; and during installation, one key of the spline is exposed to a handle face for shifting the maximum stress point to the location of the strongest point on the knob. The utility model enhances production efficiency, effectively reduces the weight of the knob, cuts manufacturing cost, reduces pollution during the manufacture process, and is consistent with the advanced concept of automotive lightweight construction.

Description

Handle in the car door

Technical field

The utility model relates to a kind of auto parts machinery, especially relates to a kind of interior handle that is used for the car door.

Background technology

Handle adopts the zinc alloy diecasting manufacturing mostly in the door of existing domestic and international automobile, adopts electroplating processes then.Its advantage is that structure is compact, intensity is high; But kirsite also exists objective defective:

1, its product weight is bigger, and the handle of kirsite has 200g approximately, and is heavy more over half than plastic products, so the cost of raw material is higher relatively.

2, owing to the process characteristic of zinc alloy casting, surface quality is poor, and die parting line is big, must carry out subsequent handling polishing processing and just can meet customer need, and the time is long, consumes cost of labor more, and polishing can generation powder contaminated environment.

3, in the kirsite manufacture process, at first must melt kirsite, have bigger energy consumption.

4, handle weight is big, can strengthen the oil consumption of automobile, does not meet the light-weighted trend of Automobile Design.

Summary of the invention

The utility model mainly is that the weight of handle in the solution existing in prior technology is big, the energy consumption height, and environment pollution, defectives such as cost height, thus develop a kind of interior handle of car door that adopts plastic production.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: handle in a kind of car door, has base, jug in the base, connecting pin on the handle, pass through the spline power transmission between handle and the pin, be with torsion spring on the pin, it is characterized in that: described handle comprises L-shaped handle and is positioned at connecting portion below the handle; Described connecting portion is provided with the spline with spline fitted, and the spline of handle connecting portion is widened, overstriking, simultaneously for fear of producing shrink mark, the part of thickening, promptly the junction of connecting portion and handle has the sulculus of some formation I-beam, to increase structural strength; Described sulculus and spline be arranged in parallel; Adopt arc transition on the length direction below the handle and between the connecting portion, be provided with vee gutter in the circular arc, described vee gutter and spline are arranged in parallel; Described spline is the triangle key, is linked to be integral body with pin; When installment state, a wherein key of spline makes its stress point with maximum adjust to the strongest place of handle towards handle surface.

As preferably, because leverage, the arm place of handle produces big shear stress, and intensity can't increase again herein, so handle afterbody bottom surface adds a salient point, with stress transfer on main body.

As preferably, handle body is partly thickeied, for preventing shrink mark, the centre at the back side is recessed, and both sides are " worker " word structure.

As preferably, described handle adopts the plastics one-shot forming.

Therefore, the beneficial effects of the utility model are: satisfying the Internal handle outward appearance, strength test, on life test and the reliability test basis, what make the grip material success makes plastics into from kirsite, has improved production efficiency, reduced handle weight effectively, reduce production costs, reduce in the manufacture process and pollute, meet the light-weighted advanced theory of Automobile Design.

The specific embodiment

Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.

Embodiment:

Shake hands in a kind of car door shown in Fig. 1-5, have base 3, the one-time formed handle 1 of the plastics of employing is arranged in the base, connecting pin 71 on the handle by spline 7 power transmissions, is with torsion spring 6 between handle and the pin on the pin 71.

As Fig. 6-handle shown in Figure 8, handle 1 comprises L-shaped handle 15 and is positioned at connecting portion 16 below the handle; Connecting portion 16 is provided with the spline 12 with spline fitted, with the spline 12 of handle 1 widen, overstriking, simultaneously for fear of producing shrink mark, the part of thickening, be the sulculuses 11 that the connecting portion 16 and the junction of handle 15 have 3 formation I-beam, increase structural strength.Because leverage, the arm place of handle 15 produces big shear stress, and intensity can't increase again herein, so handle 15 afterbody bottom surfaces add a salient point 17, with stress transfer on main body.With the main part thickening of handle 15, for preventing shrink mark, the centre at the back side is recessed, and both sides are " worker " word girder construction.On the length direction below the handle 15 and adopt arc transition between the connecting portion 16, be provided with triangular groove 14 in the circular arc, described triangular groove 14 is arranged in parallel with spline 12.The spline 7 that links to each other with pin 71 is housed in spline 12, and spline 7 is the triangle key, and when installment state, a wherein key of spline is transferred to the strongest place of handle towards handle surface with the stress point of maximum.Damper 8 is housed on pin 71.

During assembling, LED lamp 4 is buckled into base 3, again damper 8 is inserted pins 71, after base 3, spline 7, handle 1, spring 6 usefulness are riveted riveting by machine together, with spring card 5 spline 12 of packing into, at last cover plate 2 is buckled into assembly with special tool.
