Matching structure of automobile diagnosis interface plug-in

Abstract

The invention discloses a matching structure of an automobile diagnosis interface plug-in. The structure comprises a box body, the diagnosis interface plug-in and a locking structure. The box body comprises an open containing cavity; the diagnosis interface plug-in is contained in the containing cavity in a sliding mode; the locking structure comprises a fixing part and a locking part, wherein thefixing part is arranged in the diagnosis interface plug-in, and the locking part is arranged in the containing cavity; when the diagnosis interface plug-in slides to a preset position, the diagnosisinterface plug-in is locked in the containing cavity. Compared with the prior art, the matching structure is fixed in the box body through the diagnosis interface plug-in, and the box body and an electric appliance box body are integrally designed, so that the fixing positions of diagnosis interfaces are easily unified, the occupied space is small, the matching structure is not limited by the overall automobile structure and distribution space, the technical problems that diagnosis interface plug-ins corresponding to a traditional structure are different from one another and difficult to findare solved, and the diagnosis interface plug-in is safe and reliable to fix, convenient to use and good in protection effect.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a matching structure of an auto diagnostic interface plug-in. Background technique [0002] With the development of automobile technology, the degree of informatization and intelligence of automobiles is getting higher and higher. When a car breaks down, it is necessary to connect an external car-specific diagnostic device through the diagnostic interface to diagnose the fault of the whole car. [0003] The car diagnostic interface is a necessary interface for the whole vehicle. At present, the fixing method of the vehicle diagnostic interface on the market is basically fixed by bolts and nuts in the body sheet metal or directly tied to the wiring harness. [0004] refer to figure 1 , is a schematic diagram of an assembly state of the diagnostic interface plug-in in the prior art. The diagnostic interface plug-in 1001 is fixed by means of bolts and nuts. The fixed position of...

AI Technical Summary

Problems solved by technology

[0006] 1. Due to the different vehicle body structures and structures, the fixing positions of the diagnostic interface plug-in 1001 are different, making it difficult to find

[0007] 2. The diagnostic interface plug-in 1001 lacks effective protection, and is generally exposed to the external environment, and cannot effectively prevent dust, water, and foreign objects from damage

[0008] 3. The diagnostic interface has a power line, and the power-taking part is a fuse box. This kind of fixing method is generally far away from the fuse box. The farther the diagnostic interface plug-in is from the fuse box, the greater the risk of short circuit of the diagnostic power line.

[0009] 4. 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

[0012] 1. Low fixed reliability

[0013] 2. Since the wiring harness 1004 is generally arranged in the inner space of the instrument panel, it is difficult to find the diagnostic interface plug-in 1001

[0014] 3. The diagnostic interface has a power cord, and the fixing method of the diagnostic interface plug-in 1001 bundled on the wiring harness 1004 is not safe.
