Abstract:
A luminous wheel hub comprises: a wheel hub body (40), a luminous device (1) disposed on the wheel hub body (40), and an energy transformation device (2) adapted to connect with a power supply. The energy transformation device (2) comprises a first coil (21) adapted to be fixed on a caliper bracket (3) and a second coil (22) configured to rotate with the wheel hub body (40). The energy transformation device (2) is configured to output a current to the luminous device (1) only when the first coil (21) overlaps the second coil (22). A wheel and a vehicle comprising the luminous wheel hub are also provided.
Abstract:
A license plate device comprises: a first shell (110) having a transparent region (111) forming a first predetermined logo pattern and a non transparent region (112); a second shell (150) fixedly connected with the first shell (110), with a sealed accommodating space; a light guide plate (120) disposed between the bottom plate (130) and the first shell (110) which is formed with an accommodating groove (122); and a circuit board (140) disposed between the light guide plate (120) and the second shell (150) which is formed with an illuminating element (141) on a surface thereof facing toward the light guide plate (120) to be accommodated in the accommodating groove (122), in which the light guide plate (120) is formed with a plurality of microprism structures (121) configured to transmit at least a part of light emitted by the illuminating element (141) penetrating through the light guide plate (120) from a face of the light guide plate (120) facing the first shell (110).

Abstract:
A display device, a vehicle, and a method for controlling a vehicle are provided. The display device includes: a beam generator, comprising a display and configured to generate a beam having image information displayed on the display, where a size of the display is a first preset size; and a holographic optical waveguide, configured to display an image of a second preset size at a first preset distance at a position behind the display device based on the beam having the image information, where the second preset size is a preset multiple of the first preset size; and the preset multiple is greater than 1. Through the display device, eye pupils do not need to be kept in a wide-open state that causes discomfort, which avoids fatigue and myopia; experience like watching a TV series at home can be realized; and an image size can be increased without occupying more physical space of an entire vehicle.
