Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile lighting accessories, in particular to a brush conductive structure for a hub lamp. Background Art
[0002] One way to set an electric light source on the wheel hub of a car is to use the car's own power supply, which supplies power to the wheel hub either by brush (such as patent CN202220807528X) or by shrapnel (such as patent CN201821207458.4). Regardless of the method, the two electrodes must be fixed on two relatively rotating fixed components (such as the wheel hub and the steering knuckle), and are hard-connected to ensure the position stability between the two electrodes. In fact, due to the working environment of the car itself, it is inevitable that the wheel hub will often be subjected to violent impact. In this case, it is easy to cause the two electrodes to separate instantly, so that the car's own power supply cannot stably supply power to the electric light source set on the car wheel hub, thereby affecting the normal operation of the electric light source. Summary of the invention
[0003] The utility model aims to provide a hub lamp brush conductive structure, which can reliably provide power to an electric light source on a hub through a power line, and has a stable and continuous power supply and will not be interrupted.
[0004] The conductive structure of the hub lamp of the utility model is realized as follows: it includes a slip ring, a conductive ring and a brush. The slip ring includes an insulating ring base, a bearing and an insulating rotating ring. The inner ring of the bearing of the slip ring is clamped on the insulating ring base of the slip ring. The bearing adopts a roller bearing. The insulating rotating ring is clamped on the outer ring of the bearing. The conductive ring is arranged on the insulating ring base beside the bearing. The brush is arranged on the insulating rotating ring beside the bearing, and the brush rests on the conductive ring.
[0005] When in use, the utility model is fixed on the wheel hub, the power input end is connected to the brush, and the power input end of the power circuit that supplies power to the light source is connected to the conductive ring. In this way, as the wheel rotates, the conductive ring also rotates, while the brush remains relatively still. The input power is conducted to the conductive ring by the brush, and the conductive ring introduces the electric energy into the power circuit that supplies power to the light source, so that power is supplied to the electric light source through the power circuit.
[0006] Roller bearings are used. Even if the vehicle vibrates violently during operation, the roller bearings can keep the positional relationship between the insulating ring base and the insulating rotating ring stable, thereby keeping the positional relationship between the conductive ring and the brush stable, making the contact between the conductive ring and the brush reliable and ensuring stable and continuous power supply.
[0007] Preferably, the insulating ring base is connected to the outer surface of the wheel hub, or the insulating ring base is connected to the outer surface of the joint between the wheel hub and the brake disc.
[0008] Preferably, the insulating rotating ring 103 is connected to a fixed part of the car that is fixed relative to the wheel through a flexible connection. The flexible connection ensures that the insulating rotating ring and the insulating ring base can rotate relative to each other. At the same time, even if the car vibrates violently during operation, the flexible connection can adapt to such vibration to ensure that the positional relationship between the conductive ring and the brush remains stable under the action of the bearing.
[0009] Compared with the prior art, the utility model has the advantages that power can be reliably provided to the electric light source on the hub through the power line, the power supply is stable and continuous, and the power supply will not be interrupted. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] like Figure 1 , 2 As shown, the brush conductive structure for the hub lamp of the utility model comprises a slip ring 1, a conductive ring 2, and a brush 3 (conductive needle or carbon brush). The slip ring 1 comprises an insulating ring base 101, a bearing 102, and an insulating rotating ring 103. The bearing 102 adopts a roller bearing. The inner ring of the bearing 102 of the slip ring 1 is clamped on the insulating ring base 101 of the slip ring 1, and the insulating rotating ring 103 is clamped on the outer ring of the bearing 102. The conductive ring 2 is arranged on the insulating ring base 101 next to the bearing, and the brush 3 is arranged on the insulating rotating ring 103 next to the bearing, and the brush 3 rests on the conductive ring 2.
[0016] A guide hole 104 is provided on the insulating rotating ring 103 , and the brush 3 is slidably arranged in the guide hole 104 . A spring 4 is provided between the guide hole 104 and the brush 3 .
[0017] Preferably, the insulating ring base 101 is fixedly connected to the outer surface of the wheel hub A, or the insulating ring base 101 is fixedly connected to the outer surface of the joint between the wheel hub A and the brake disc.
[0018] Preferably, the insulating rotating ring 103 is connected to a fixed part (such as a caliper base or a steering knuckle) of the vehicle that is fixed relative to the wheel through a flexible connection.
[0019] When in use, the utility model is fixed on the wheel hub A, the power input end is connected to the brush 3 through the power line 5, and the power input end of the power circuit that supplies power to the light source is connected to the conductive ring 2 through the power line 5. In this way, as the wheel rotates, the conductive ring 2 also rotates, while the brush 3 remains relatively still. The input power is conducted to the conductive ring 2 by the brush 3, and the conductive ring 2 introduces the electrical energy into the power circuit that supplies power to the light source, so as to supply power to the electric light source through the power circuit.
