Abstract

The utility model provides a BOSS post structure for it is fixed between part. BOSS post integrated into one piece is on the part body, the cylinder part of BOSS post and the back that the brace rod all is located the part body, expose in part body surface the upper end of cylinder part, play the guiding orientation effect, the part body is as the flange face, with compressed tightly by retaining element laminating, ensure when the fastening, the part body is laminated as the flange face with by the retaining element completely, compress tightly, do not sink, the possibility of dislocation, thereby can avoid the not enough problem of intensity that traditional BOSS post brace rod appears as the flange face.

Description

A kind of for BOSS rod structure fixing between part

Technical field

This utility model relates to the BOSS rod structure connecting two parts.

Background technology

Automobile interior exterior decorations part provides comfortable environment of taking for passenger, and plays decoration interior space and improve the effect of automotive quality sense, and fastening between each part under interior exterior trim assembly part, the reliability of assembling, concordance are just particularly important.

BOSS post, formal name used at school projection, open tubular column, be the cylinder with connecting hole on product, is commonly used to connect two parts, and supports a part on the face-piece of another part, makes part more can bear from extraneous pressure.

BOSS post is one of attachment structure mode between two common at present parts, existing common BOSS rod structure is such as shown in Fig. 4, Fig. 5, Fig. 6, BOSS post is on part noumenon 2, centered by cylinder 1 with screw, a plurality of brace rod 7 is had around cylinder, top one plane of composition of all brace rods, as brace rod flange face 3, another is fitted on BOSS post by retaining element 5 by brace rod flange face 3, realized the connection of two parts by the fastening of fixing screw 4, above BOSS rod structure exists following not enough:

1, each brace rod 7 is too high, wall thickness is thin, intensity is not enough, flange face 3 limited strength at brace rod top, it is easy to occur that brace rod subsides problem.

2, when the flange face of fixing screw 4 with had included angle A ° by the flange face of retaining element 5 time, when screw 4 fastens, cause that glass retaining element 5 even doubles with the increase of BOSS intercolumniation local pressure, again because of brace rod flange face 3 limited strength, very easily occur subsiding, the problem such as dislocation, and then the reliability of impact fastening, concordance.

Utility model content

This utility model is a kind of for BOSS rod structure fixing between part, effectively solves what traditional B OSS rod structure occurred the problem that brace rod intensity deficiency is easily subsided, subject range is limited.

For solving above-mentioned technical problem, this utility model takes following technical proposals:

A kind of for BOSS rod structure fixing between part, BOSS post is one-body molded on part noumenon, the columnar part of BOSS post and brace rod are respectively positioned on the back side of part noumenon, the upper end of columnar part is exposed to part noumenon surface, playing guide-localization effect, part noumenon is as the flange face with compression of being fitted by retaining element.

This utility model is owing to all designing the behind at part noumenon by BOSS post main part and brace rod, only fraction plays guide-localization effect in the front end of body, so when fastening, part noumenon is fitted completely as flange face with by retaining element, is compressed, the probability do not subside, misplaced, such that it is able to evade the relevant issues that traditional B OSS post brace rod occurs as flange face intensity deficiency, it is especially applicable in screw flange face and the occasion being had included angle A ° by the flange face of retaining element, effectively makes up the deficiency of traditional B OSS post.

This utility model is particularly well-suited to the connection fastening of automobile interior exterior decorations part.

Accompanying drawing explanation

Fig. 1 is BOSS rod structure schematic diagram of the present utility model.

Fig. 2 is the part annexation figure using this utility model BOSS rod structure.

Fig. 3 is the B-B profile of Fig. 2.

Fig. 4 is the schematic diagram of traditional B OSS rod structure.

Fig. 5 is the part annexation figure using traditional B OSS rod structure.

Fig. 6 is the A-A profile of Fig. 5.

In figure, 1 BOSS post cylinder, 2 part noumenons, 3 brace rod flange faces, 4 fixing screws, 5 by retaining element, 6 part noumenon flange faces, 7 brace rods.

Detailed description of the invention

Carry out a step below in conjunction with accompanying drawing and describe structure of the present utility model in detail:

The connection fastening of part is adornd for automobile interior exterior, BOSS rod structure of the present utility model is as shown in Figure 1, BOSS post cylinder 1 and brace rod 7 are arranged at the part noumenon back side, the surface of part noumenon is as flange face 6, namely flange face 6 is a part for part noumenon, therefore is absent from, during assembling, the problem that intensity is weak, subside.BOSS post cylinder 1 only upper end is a bit of exposes in flange face 6 front end, play guide-localization effect.

Referring to Fig. 2 and Fig. 3, when using this BOSS rod structure to carry out part connection, it is that flange face 6 is in being fitted by the flange face of retaining element 5, compressing by part noumenon, when fixing screw 4 flange face with had included angle A ° by the flange face of retaining element 5 time, even if local pressure strengthens, even doubles, pressure is transmitted to part noumenon flange face 6 by connected part, born by part noumenon flange face 6, will not all be applied on BOSS post brace rod 7, so there is no that intensity risk occurs subside, the problem such as dislocation.

Claims

1. the BOSS rod structure for fixing between part, BOSS post is one-body molded on part noumenon, it is characterized in that: the columnar part of BOSS post and brace rod are respectively positioned on the back side of part noumenon, the upper end of columnar part is exposed to part noumenon surface, plays guide-localization effect, and part noumenon surface compresses with by retaining element laminating as flange face.
