Description

Technical Field

[0001] This invention relates to the field of automotive sub-instrument panel technology, and in particular to a positioning structure for automotive sub-instrument panels. Background Technology

[0002] Currently, the front end of the automotive sub-instrument panel is mostly fitted to the instrument panel with screws, which only provides positioning in the X and Z directions and cannot guarantee the Y-direction clearance between the sub-instrument panel and the instrument panel after installation. The rear of the sub-instrument panel is positioned onto the sheet metal bracket by drilling small holes. Due to the large size of the sub-instrument panel and its easy deformation, it is difficult to quickly assemble it in place during the actual assembly process, which affects the assembly rhythm.

[0003] For example, Chinese patent CN208498247U discloses a mating structure between a sub-instrument panel and an instrument panel, including a sub-instrument panel and an instrument panel, which are fixedly connected by screws; the instrument panel has a positioning groove at the position corresponding to the sub-instrument panel, and the front end of the sub-instrument panel is embedded in the positioning groove. Through the positioning groove, the mating between the sub-instrument panel and the instrument panel is transformed from a surface contact to a "hidden" concept, concealing the gaps in the direct fit. Thus, the gaps and surface differences between the two are hidden; however, it does not completely solve the problem of mating gaps, only making them invisible. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a positioning structure for automotive sub-instrument panels, which can accurately fix and assemble the sub-instrument panels into place, thereby improving the assembly effect.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] The automotive sub-instrument panel positioning structure has the front end of the sub-instrument panel cooperating with the lower instrument panel for positioning, and the rear end of the sub-instrument panel cooperating with the sheet metal bracket on the vehicle body for positioning. The front end of the sub-instrument panel and the lower instrument panel are positioned by a positioning pin hole structure and a front-end positioning surface, and the rear end of the sub-instrument panel and the sheet metal bracket are positioned by a protruding positioning structure and a rear-end positioning surface.

[0007] Further:

[0008] The positioning pin hole structure includes a set of guide positioning pins located at the front end of the sub-instrument panel and positioning holes located on the lower guard plate of the instrument panel that are adapted to the guide positioning pins.

[0009] The front-end mating positioning surface includes a front-end positioning surface located at the front of the sub-instrument panel and a front-end X-direction positioning surface located on the lower panel of the instrument panel that is adapted to the front-end positioning surface.

[0010] The sub-instrument panel has a central positioning hole in the middle of its body.

[0011] The raised positioning structure includes a rear Y-direction positioning boss located at the rear end of the sub-instrument panel and a rear Y-direction positioning hole located on the sheet metal bracket. The rear Y-direction positioning boss and the rear Y-direction positioning hole cooperate for positioning.

[0012] The rear-end mating positioning surface includes a sheet metal positioning surface on the sheet metal bracket and a rear-end Z-direction positioning surface at the rear of the sub-instrument panel, and the sheet metal positioning surface and the rear-end Z-direction positioning surface are mated for positioning.

[0013] The set of guide positioning pins are arranged side by side in a horizontal direction.

[0014] The front positioning surface is provided with a fastening screw, and the front X-direction positioning surface is provided with a nut that matches the fastening screw.

[0015] The rear Y-direction positioning hole is a square hole, and the rear Y-direction positioning boss is a pair of protrusions arranged side by side. One protrusion mates with one side of the square hole, and the other protrusion mates with the other side of the square hole.

[0016] The rear Z-axis positioning surfaces are a group distributed at the four corners, and each rear Z-axis positioning surface is provided with bolt holes. The sheet metal positioning surface is provided with welded fixing nuts corresponding to the bolt holes.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] The automotive sub-instrument panel positioning structure is reasonably designed. Through the positioning structures at the front and rear of the sub-instrument panel, it can be accurately fixed to the vehicle, ensuring the fit clearance between the sub-instrument panel and the lower structure of the instrument panel, and can be quickly and accurately assembled, thus improving production efficiency.
