An automobile diagnostic interface fixing structure fixed on the electrical box body

Abstract

The invention relates to an automobile diagnosis interface fixing structure fixed on an electric appliance box body. The automobile diagnosis interface fixing structure comprises the electric appliance box body, a diagnosis interface plug-in fixing structure and a diagnosis interface plug-in. The diagnosis interface plug-in fixing structure and the electric appliance box body are formed through injection molding in an integrated mode and form an integrated structure. The diagnosis interface plug-in is movably connected with the diagnosis interface plug-in fixing structure. The diagnosis interface plug-in fixing structure is designed on the electric appliance box, and the technology of integrated forming through injecting molding is adopted, so that diagnosis interface plug-ins can be fixed on the electric appliance box uniformly, and the standardization and uniformity of positions of diagnosis interfaces are realized.

Description

technical field [0001] The invention belongs to the field of automobile electric appliances, in particular to an automobile diagnosis interface fixing structure fixed on the electric box body. Background technique [0002] With the development of automobile technology, the degree of informationization and intelligence of automobiles is getting higher and higher. When a car breaks down, it is necessary to connect the diagnostic interface and external car-specific diagnostic equipment to diagnose the fault of the whole car. [0003] The automobile diagnostic interface is a necessary interface for the whole vehicle above the National III emission level. At present, the fixing method of the vehicle diagnostic interface on the market is basically fixed by bolts and nuts with holes in the body sheet metal or directly tied to the wiring harness. The automotive diagnostic interface plug-in is basically universal on various models, that is, the diagnostic interface plug-in models of ...

AI Technical Summary

Problems solved by technology

[0007] 1. Due to the different body structure and structure of each model, the fixing positions of the diagnostic interface plug-in are different, making it difficult to find

[0008] 2. Because it must be easy to connect an external diagnostic device, the diagnostic interface plug-in is easily limited by the lack of space in the vehicle, so it is necessary to reserve enough space on the sheet metal, and the layout is difficult

[0009] 3. Generally, it is necessary to design a special diagnostic maintenance cover

[0011] 5. Using the fixing method of bolts and nuts, the production and assembly efficiency is low and the cost is high. This kind of assembly method needs to be assembled in the automobile assembly workshop

[0014] 1. Low fixed reliability

[0015] 2. Since the wiring harness is generally arranged in the internal space such as the instrument panel, it is difficult to find the diagnostic interface plug-in

[0016] 3. Need to design a special diagnostic access cover

[0017] 4. The diagnostic interface has a power cord, and the fixing method of the diagnostic interface plug-in bundled on the wiring harness is not safe.
