Description

Technical Field

[0001] This utility model relates to the technical field of vehicle fault OBD detection instruments, specifically a vehicle fault OBD detection instrument. Background Technology

[0002] An OBD (On-Board Diagnostics) diagnostic tool is a device used to detect vehicle malfunctions. It can read fault codes stored in the vehicle's electronic control unit (ECU), which are information recorded by various electronic systems of the vehicle (such as the engine, transmission, anti-lock braking system, etc.) when abnormal conditions occur.

[0003] Existing vehicle fault OBD diagnostic tools require plugging them into the vehicle for testing. After testing, the plug is unplugged, leaving it exposed to the air. Over time, dust accumulates on the exposed plug surface, affecting the connection stability between the OBD diagnostic tool and the vehicle, leading to inaccurate detection results. Utility Model Content

[0004] The purpose of this utility model is to provide a vehicle fault OBD detector that has the advantage of stable connection between the vehicle fault OBD detector and the vehicle, and solves the problem that the plug of the current vehicle fault OBD detector is exposed when not in use, which is prone to dust accumulation and affects the connection stability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vehicle fault OBD detector, including a detector, a transmission line is provided at the top of the detector, a winding mechanism is provided on the back, a connecting mechanism is provided at the end of the transmission line, the connecting mechanism includes a plug, two flip covers are symmetrically rotated and installed on the plug, each flip cover has a first groove on the side facing the plug, a second groove is provided in the first groove, and a magnetic strip is provided at the contact part of the two flip covers.

[0006] Preferably, the flip cover has a hollow cavity structure, and the two flip covers together form a rectangular protective shell. The flip cover has a chamfering structure on the side near the rotation axis.

[0007] Preferably, the winding mechanism includes a short column, one end of which is attached to the back of the detector, and the other end is provided with a circular plate. A protruding post is provided on the side of the circular plate away from the short column, and the length of the circular plate is greater than the diameter of the transmission line.

[0008] Preferably, the top of the circular plate is provided with a take-up groove, the width of the take-up groove is greater than the diameter of the transmission line, and both ends of the take-up groove are provided with rounded corners.

[0009] Preferably, the length of the protruding post is equal to the thickness of the connecting mechanism.

[0010] Preferably, a rotating plate is elastically connected to the end of the protruding post away from the short post, and a limit block is provided at the end of the rotating plate away from the protruding post, and the length of the rotating plate is equal to the width of the connecting mechanism.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting a plug, flip cover, first groove, second groove, magnetic strip and chamfering structure, allows the two flip covers to rotate with the plug. During rotation, the chamfering structure can prevent the two flip covers from getting stuck. The magnetic strip on the flip cover can fix the two flip covers and protect the plug when it is not in use, preventing dust from sticking to the pins of the plug and affecting the stability of the transmission connection.

[0013] 2. This utility model, by setting up a short column, a circular plate, a take-up groove, a protruding column, a rotating plate, and a limiting block, uses a take-up reel composed of the short column and the circular plate to wind the transmission line around the outer edge of the short column. The take-up groove flips the connecting mechanism to the side of the circular plate away from the short column. The rotating plate on the protruding column rotates and fits the connecting mechanism, and the limiting block locks it in place, thus fixing the connecting mechanism. When not in use, the wiring harness of the vehicle fault OBD detector can be stored, improving aesthetics. Attached Figure Description
