The invention relates to a baby carriage with a flashing function. The baby carriage comprises a carriage body and a flashing device arranged on the carriage body. The flashing device comprises multiple light-emitting elements, a control unit, a vibration sensing unit, a light sensing unit, a change-over switch and a power supply unit. The vibration sensing unit is used for receiving a vibration signal of the carriage body, converting the vibration signal into a corresponding electrical signal and transmitting the electrical signal to the control unit. The control unit controls the light-emitting elements to emit light according to the electrical signal. The light sensing unit is used for detecting the intensity of ambient light and transmitting a detection signal to the control unit, and the control unit controls the light-emitting elements to emit the light or not according to the detection signal. The change-over switch is used for performing switching between the vibration sensing unit and the light sensing unit. Vehicle drivers on the road can conveniently take notice of the baby carriage when people push the baby carriage for traveling at night, and it can be prevented that because the vehicle drivers can not see the baby carriage clearly, traffic safety accidents are generated.

The invention aims to provide an intelligent identification safe driving early warning system and a working method thereof. The system is composed of an advancing induction module, a signal transmission module and a data collection and analysis module. The advancing induction module is composed of a plurality of motor vehicles, wherein each motor vehicle is provided with eight monitors, two pedestrian recognition devices and an automatic brake device, and each monitor is composed of a shell, a suction cup piece, a camera, a circuit board, a power source, a data processor, a signal sending device and an indicator lamp. According to the whole system, eight monitors are arranged on each motor vehicle; the transmission of a wireless network and the data analysis and output of a server are matched. ,The pedestrians pass through two static vehicles can be monitored in real time, so that an early warning signal is sent to a driver who finds abnormal conditions, the automatic braking functionis activated in time, driving risks caused by visual blind areas and misunderstanding are avoided, emergency protection is achieved on the pedestrians, and then traffic safety accidents are avoided.

The invention discloses a gear reversing device for motorcycle engine transmission. The input end of a main shaft of a transmission in a crankcase passes through a right crankcase and fixes a reverse driving gear on the cover-closing side of the right crankcase in the circumferential direction; a reverse gear is fixed on a countershaft of the transmission in the circumferential direction; the cover-closing side of the right crankcase is provided with an intermediate gear mechanism; a first gear of the intermediate gear mechanism meshes with the reverse driving gear on the main shaft; a second gear is corresponding to the reverse gear on the countershaft; a limit boss for preventing from entering reverse gear is arranged on the end face of a star-shaped shift wheel; and the cover-closing side of the right crankcase is provided with a reverse gear protection mechanism in constant contact with the limit boss on the star-shaped shift wheel.
