Vehicle remote OBD diagnosis device

Abstract

The invention relates to the technical field of vehicle remote OBD diagnosis and discloses a vehicle remote OBD diagnosis device comprising an OBD main body. The two side walls of the OBD main body are fixedly connected with connection blocks correspondingly. The ends, away from the OBD main body, of the two connection blocks are slidably connected with a U-shaped base together. First slide grooves matched with the connection blocks are formed in the opposite sides of two vertical parts of the U-shaped base correspondingly. The upper surface of a horizontal part of the U-shaped base is fixedlyconnected with two symmetrically-distributed first telescopic rods. According to the vehicle remote OBD diagnosis device, the situations that the vehicle remote OBD diagnosis device is affected by the jolt of a vehicle, and damaged due to working in the high temperature environment can be avoided; it is ensured that the OBD diagnosis device is not damaged; meanwhile, the diagnosis accuracy of theOBD diagnosis device is improved; normal work of the OBD diagnosis device is guaranteed, and the service life of the OBD diagnosis device is prolonged; and in addition, the OBD diagnosis device can be mounted without being fixed by bolts, so that the time and effort are saved, and the mounting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle remote OBD diagnosis, in particular to a set of vehicle remote OBD diagnosis device. Background technique [0002] OBD is an "on-board diagnostic system". This system monitors the operating status of the engine and the working status of the exhaust after-treatment system at any time. Once it finds that the emission may exceed the standard, it will immediately issue a warning. When the system fails, the fault light or check The engine warning light is on, and the OBD system will store the fault information in the memory at the same time, and the relevant information can be read in the form of fault codes through standard diagnostic instruments and diagnostic interfaces. According to the prompts of the fault codes, the maintenance personnel can quickly and accurately determine the nature of the fault It adopts the original vehicle driving computer detection technology, GPRS data transmission technol...

Problems solved by technology

[0003] The existing OBD diagnostic device is directly installed in the installation slot inside the car, but during the driving process of the car, long-term bumps and shakes will damage the OBD diagnostic device, which will easily lead to inaccurate diagnosis and affect its normal work. In addition, OBD When the diagnostic device is working, the surrounding temperature is high due to the heat emitted by itself and the car. The OBD diagnostic device works in a high temperature environment, which may easily lead to the accuracy of its diagnosis, and it is easy to damage the electronic components in the OBD diagnostic device, affecting its normal operation. work and service life
