Description

Improved structure of conductive slip ring for hub lamp

Technical Field

The utility model relates to the technical field of automobile light fittings, in particular to an improved structure of an electric conduction slip ring for a hub lamp.

Background

The electric light source is arranged on the automobile hub, one of the modes is to adopt an automobile self-contained power supply, the mode of supplying power to the hub is either in a brush mode (such as patent CN 202220807528X) or in a shrapnel mode (such as patent CN 201821207458.4), and both electrodes are required to be fixed on two relatively rotating fixing members (such as the hub and a knuckle) and are hard-connected to ensure stable positions between the two electrodes, and in fact, the hub is inevitably subjected to intense impact due to the working environment of the automobile, and in this case, the two electrodes are easily separated instantaneously, so that the automobile self-contained power supply cannot stably supply power to the electric light source arranged on the automobile hub, and the normal operation of the electric light source is affected.

Disclosure of Invention

The utility model aims to provide an improved structure of a conductive slip ring for a hub lamp, wherein power is reliably supplied to an electric light source on a hub through a power line, the power supply is stable and continuous, and the power supply cannot jump.

The utility model is realized in the following way: including insulating ring base, the bearing, insulating fixed ring, electrically conductive spring down, electrically conductive spring up, insulating ring base is fixed in the wheel hub inboard, be provided with down the spring blind hole above the insulating ring base, the electrically conductive spring down that is connected with the wire that supplies power to the wheel hub lamp sets up in spring blind hole down, the bearing hoop is on insulating ring base, the bearing inner race of bearing covers down the spring blind hole, make the electrically conductive bearing inner race that leans on the bearing of bearing down, insulating fixed ring hoop is on the bearing outer race of bearing, be provided with the spring blind hole on the medial surface of bearing outer race of insulating fixed ring towards the bearing, the electrically conductive spring up that is connected with the power supply wire sets up in the spring blind hole, electrically conductive spring up is on the bearing outer race of bearing in the bearing of tight.

When the bearing is used, the bearing serving as a conductor is fixed on the inner side of the hub, the bearing inner ring of the bearing rotates along with the rotation of the hub, and the connection between the bearing outer ring of the bearing and a wire is determined by the structure of the bearing and the soft connection, so that even if the hub is frequently subjected to intense impact, the bearing inner ring of the bearing and the bearing outer ring can be tightly connected, and the power supply is stable and continuous, and the power supply cannot jump.

Compared with the prior art, the utility model has the advantages that the power is reliably supplied to the electric light source on the hub through the power line, the power supply is stable and continuous, and the power supply cannot jump.
