1. A toy vehicle comprising:
- a chassis comprising an upper surface and a lower surface opposite to the upper surface;
at least one light guide plate comprising a first portion embedded into the chassis from the upper surface and projecting from the lower suface, and a second portion connected to the first portion;
at least one sensor unit attached to the second portion of the light guide plate, the at least one sensor unit comprising an emitter for emitting light at certain wavelength and a detector for receiving the certain wavelength light emitted by the emitter and sending a signal according to a propagation delay of a light of certain wavelength emitted from the emitter and received by the detector; and
a driving unit mounted on the chassis and electrically connected to the at least one sensor unit, the driving unit being configured for controlling the toy vehicle according to the signals outputted from the detector of the at least one sensor unit.

Abstract
A toy vehicle includes a chassis, at least one light guide plate, at least one sensor unit and a driving unit. The at least one light guide plate includes a first portion and a second portion and is embedded into the chassis by the first portion. The at least one sensor unit is attached on the second portion of the at least one light guide plate and includes an emitter for emitting light, and a detector for receiving the reflected light and sending a signal according to a propagation delay of a light emitted from the emitter and received by the detector. The driving unit is configured for controlling the motion of the toy vehicle according to the signal outputted from the at least one sensor unit.
