Abstract

The invention provides an assembly structure of an automobile instrument panel assembly and an automobile body front wall metal plate. The instrument panel assembly is formed by integrally welding a defrosting air pipe body subjected to injection molding and an instrument panel body, wherein positioning structures with Y-shaped sections are integrally formed on one side of the left end and one side of the right end of the defrosting air pipe body facing the automobile body front wall metal plate through injection molding; and a seam allowance edge of the automobile body front wall metal plate matched with the Y-shaped positioning structures is directly inserted into the Y-shaped positioning structures at the left and right ends of the defrosting air pipe body. The positioning structures with the Y-shaped sections are directly formed at the left and right ends of the defrosting air pipe body and are matched with the seam allowance edge of the automobile body front wall metal plate to position an instrument panel in a Z direction and an X direction, and the assembly structure is simple and can effectively solve the problem that the front end of the instrument panel is wavelike deformed.

Description

The mounting structure of a kind of automobile instrument panel assembly and body front wall panel beating

Technical field

The present invention relates to the automobile instrument panel assembly of automobile.

Background technology

The Defroster device for vehicle airduct provides front windshield glass and side window glass defrosting-defogging air-flow usefulness, to satisfy the requirement of automobile air window glass defrosting-defogging rules.Referring to Fig. 1, the more and more employing injection mo(u)ldings of defrosting air pipe 1 now, and friction welding is vibrated in employing and instrument carrier panel body 2 is integrally welded, form panel assembly, referring to Fig. 2 and Fig. 3, like this front of dash is played obvious booster action, certain improvement effect has also been played in distortion to the front of dash waveform.But because panel assembly is with the assembling of body front wall panel beating the time, the front of dash orientation problem does not solve, and still there is bigger waveform distortion in front of dash.

Summary of the invention

The present invention proposes the mounting structure of a kind of automobile instrument panel assembly and body front wall panel beating, the defrosting air pipe main body structure is improved, self have front of dash both sides location structure thereon, need not installing and locating guide finger on the instrument carrier panel body again, this kind infrastructure cost is cheap, and can solve the front of dash orientation problem well.

Purpose of the present invention is achieved through the following technical solutions:

The mounting structure of a kind of automobile instrument panel assembly and body front wall panel beating, described panel assembly is that one constitutes by the defrosting air pipe body and the weldering of instrument carrier panel body of injection mo(u)lding; It is characterized in that: be formed with the location structure of cross section for " Y " font at the two ends, the left and right sides of described defrosting air pipe body towards the one side one injection moulding of body front wall panel beating, directly insert in the location structure of " Y " font at two ends, the defrosting air pipe body left and right sides on described body front wall panel beating seam with matching limit.

Further, the bottom of the location structure of described " Y " font is provided with spacing muscle, and push up on the spacing muscle of location structure on the seam limit of body front wall panel beating; The seam limit of described body front wall panel beating is provided with positioning bar, on the location structure of " Y " font locating notch is arranged, and positioning bar snaps in the locating notch on the location structure of " Y " font, to front of dash Z to X to the location.

The present invention is by directly making the location structure of cross section for " Y " font at the two ends, the left and right sides of defrosting air pipe body, by cooperating with the seam limit of body front wall panel beating, to instrument carrier panel carry out Z to X to the location, simple in structure, can effectively solve front of dash waveform problem on deformation.

The specific embodiment

Describe specific embodiments of the present invention in detail below in conjunction with accompanying drawing:

As Fig. 3, Fig. 4 and shown in Figure 5, the defrosting air pipe body 3 after the improvement is injection mo(u)lding, and the two ends, the left and right sides of defrosting air pipe body 3 directly have the location structure 4 of cross section for " Y " font after the injection mo(u)lding.

Referring to Fig. 6, Fig. 7 and Fig. 8, defrosting air pipe body 3 adopts the weldering of vibration friction welding to be one with instrument carrier panel body 2, forms panel assembly.After defrosting air pipe body 3 was one with 2 welderings of instrument carrier panel body, the front end intensity of instrument carrier panel body 2 was obviously strengthened, and distortion can be played good improvement effect to the front of dash waveform.

When panel assembly that is welded as a whole and body assembling, with defrosting air pipe body about 3 two end sections is the location structure 4 aligning body front wall panel beatings 8 seam with matching limits 7 of " Y " font, push away panel assembly forward, make the seam limit 7 of body front wall panel beating insert defrosting air pipe body about 3 two end sections in the location structure 2 of " Y " font, the location structure 4 of " Y " font has the assembling directional tagging, when Y is pushed up on the seam limit 7 of body front wall panel beating " during the spacing muscle 6 of location structure 4 bottoms of font; 5 of the positioning bars on the seam limit 7 of body front wall panel beating snap in breach limit on the location structure 4 of " Y " font, so just can realize reliably front of dash Z to X to the location.

Claims
