Description

Wheel hub lamp circuit structure

Technical Field

The utility model relates to a light fitting technology for an automobile, in particular to a wheel hub light circuit technology.

Background

The automobile hub is provided with an electric light source which is provided with a power supply in two modes, wherein one mode is a self-contained generator which generates electricity by utilizing the rotation of the hub, the mode needs to install power generation equipment on the rotating hub and is determined by the structure of the power generation equipment, the power generation equipment has certain weight, and the wheel of the automobile needs to rotate at high speed, so the dynamic balance requirement is high, the power generation equipment is required to be corrected after the hub is provided with the power generation equipment, therefore, the use is inconvenient, and the power generation equipment has heavier weight, so the correction of the dynamic balance is not easy, moreover, the cost is high by adopting the power generation equipment, the quality of the generated electricity is unstable, and the requirements of various light-emitting forms of various electric light sources are not easy to meet; the other mode is that the automobile is adopted and is provided with a power supply, as disclosed in patent CN201821207458.4, two circles of circle circuit boards 5 are arranged on a brake disc 7 linked with a hub, a positive metal elastic sheet 3 and a negative metal elastic sheet 4 are fixed on an automobile body sheet metal part 9 through a metal elastic sheet support 2, the free end of the positive metal elastic sheet 3 and the free end of the negative metal elastic sheet 4 lean against the two circles of circle circuit boards 5 respectively, thus, the power supply of the automobile with a storage battery transmits the power supply to the two circles of circle circuit boards 5 through the free end of the positive metal elastic sheet 3 and the negative metal elastic sheet 4, and the upper side of the two circles of circle circuit boards 5 transmits the power supply to an electric light source arranged on the hub. In the power supply technology, the two circles of circular circuit boards 5 must supply power to the electric light source on the hub through the power line, which is determined by the rotation of the brake disc 7 relative to the caliper 8, and the power line must also rotate relative to the caliper 8, so that the power line is easily damaged by touching the caliper 8, and the power supply failure is caused.

Disclosure of Invention

The utility model aims to provide a hubcap circuit structure which is provided with a power supply reliably supplied to an electric light source on a hubcap through a power supply wire, is not easy to damage the power supply wire and is stable and continuous in power supply without jumping off. The utility model is realized by the following steps: the electric brush comprises a circular ring-shaped power transmission ring member, an electric brush base and an electric brush, wherein the circular ring-shaped power transmission ring member is fixed on a spoke of a hub and supplies power to an electric light source arranged on the hub through a wire, the electric brush base is fixed on a caliper base, and the electric brush is arranged on the electric brush base and is supplied with power by a vehicle-mounted power supply.

Because the annular electricity transmission ring component is arranged on the spoke of the hub, and the spoke of the hub and the hub are far away from the caliper on the brake disc, even if the hub rotates relative to the caliper, a lead arranged on the hub cannot interfere with the caliper to cause damage. When power is supplied, the conducting ring is used for supplying a positive power supply, and the hub is used as a negative electrode, so that the power supply to the electric light source on the hub is realized only by the annular conducting ring member and the electric brush, and the structure is simplified.

Here, the conductive ring contact surface of the annular power transmission ring member is located on the side surface, and the brush is abutted against the conductive ring contact surface from the side surface. The automobile wheel jolts up and down to generate high-strength high-frequency up-and-down vibration, and if the electric brush is contacted with the contact surface of the conducting ring from the vertical direction, the electric brush is easily in poor contact with the contact surface of the conducting ring due to vibration to frequently cut off the power supply, so that the normal work of the electric light source is influenced. The problem is solved by adopting the contact from the side surface, and the diameter of the contacted conducting ring is smaller and the linear velocity is small by adopting the side surface contact, so that the abrasion of the electric brush is effectively reduced.

The annular electricity transmission ring component is arranged at the root of the spoke of the hub, so that the diameter of the electricity transmission ring is reduced to the maximum extent, the linear velocity is reduced, and the abrasion of the electric brush is reduced.

The annular electricity transmission ring component comprises an insulating ring and a conducting ring arranged on the insulating ring.

The electric brush base is provided with a hole, the electric brush is inserted into the hole, and a spring is arranged between the hole and the electric brush. Thus, the brush is abutted against the conductive ring by the elastic force of the spring.

The electric brush comprises a guide post and a graphite rod arranged on an embedding hole at the front end of the guide post.

Here, a PLC control device is provided, which controls the manner in which the on-board power supply supplies power to the electric light source.

Compared with the prior art, the utility model has the beneficial effects that: the hub has the advantages that the power supply is reliably provided for the electric light source on the hub through the power line, the power line is not easy to be damaged, and the power supply is stable and continuous without tripping.
