Abstract

The utility model relates to the spacing rod profile structure of an automobile door opening spacing device. A spacing rod has the whole shape of a circular arc with the radius of 205mm, the linear distance between two end holes is 108mm, and a spacing rod stopping groove has the width of 5mm and the depth of 1.5mm. The bottom of the spacing rod stopping groove is a circular arc with the radium of 1mm and is smoothly connected with a circumjacent profile through a circular arc with the radius of 10mm, and the linear distance between two grooves is 16mm. The spacing rod profile can match elasticity best to ensure the smoothness and the level during the starting of an automobile door and increases the level of the automobile door.

Description

The spacing rod face structure of automobile door opening stop

Technical field

The utility model belongs to arrangements for automotive doors and opens and closes caging system, is specifically related to the spacing rod face structure design of automobile door opening stop.

Background technology

The commonly used door open limit device of automobile as shown in Figure 1,1 is vehicle body among the figure, the 2nd, car door, the 3rd, elastic body, the 4th, roller, the 5th, block rubber, the 6th, gag lever post, the 7th, housing.Its basic principle is by elastic body elastic force to be affacted on the roller, and roller slides on gag lever post, and the variation by spacing rod face makes car door realize off-position in a certain angle.

The automobile door opening stop has two functions, and the one, the maximum opening of restriction car door, the 2nd, the off-position function during the half-open and standard-sized sheet of door.Because its same frequency of utilization height with door hinge is so require it that very high durability and reliability are arranged.In addition, also require spring force to cooperate and want rationally shift feeling to be arranged, guarantee the smoothness that opens and closes again with spacing rod face.

At present to be that the shape face of gag lever post is difficult mate with spring force the subject matter that occurs of automobile door opening stop, when causing opening the door or comparison painstaking (spacing surplus), perhaps do not have shift feeling (spacing deficiency).Therefore, the shape face of gag lever post is the key point that solves these problems of door open limit device.

Summary of the invention

The purpose of this utility model is the deficiency that exists at prior art, and a kind of spacing rod face structure of automobile door opening stop is provided, and realizes the coupling of spacing rod face and spring force, makes spacing producing a desired effect, and solves the coupling difficult problem of stop.

Design of the present utility model is based on following analysis:

(1) theory analysis of the gag lever post arm of force and opening angle relation

We require stop half-open in the time of 40 °, standard-sized sheet in the time of 70 °, and these two angles must realize the off-position function to car door.At first we have analyzed the moment situation of gag lever post 7, and as shown in Figure 2, wherein F is for keeping the required power of aperture, and 0 is hinge axes, and L is the arm of force of confining force.Moment M=FL then.In car door 2 opening processes, the arm of force is constantly to change.The relation of the arm of force and relevant parameter as shown in Figure 3, wherein 0 is hinge axes, A is an opening angle, β is a start angle, L is the arm of force, I is a fully open position, II is a half-open position, III is a fastening position.Through theory analysis, it is as follows to have obtained the arm of force design formulas in the opening process:

c ²＝g ²+R ²-2gRcos(β+A) (1)

a＝(c ²+g ²-R ²)/2c (2)

L ²＝g ²-a ² (3)

According to theory analysis and experience in the past, we have determined that at first the reasonable numerical value of Several Parameters is:

R＝80mm β＝15.5° g＝98mm

By formula (1)-(3), calculate the theory relation of the gag lever post arm of force and opening angle, and analyze critical relation, as shown in Figure 4, the theory relation curve from Fig. 4 as can be seen, the arm of force in the time of 40 ° should be 75mm, the arm of force in the time of 70 ° should be 64mm.

Therefore when the shape face design of carrying out gag lever post, considered this requirement with resitting an exam.Take all factors into consideration the influence of each side factor, we design spacing rod face, and suitably adjust according to test, final shape face structure design is: the spacing rod face structure of the automobile door opening stop that the utility model adopts is: the gag lever post global shape is the circular arc of radius 205mm, two stomidium air line distance 108mm, gag lever post off-position recess width is 5mm, the degree of depth is 1.5mm, bottom land is the circular arc of radius 1mm, and be that the circular arc of 10mm and peripheral shape face are smooth along connecing by radius, air line distance is 16mm between two grooves.

The effect of invention

This spacing rod face can reach extraordinary coupling with spring force owing to calculate and test and adjust through strict theory, thereby guarantees the smoothness and the shift feeling of car door opening, improves the shift feeling of car door.
