Saddle having laser projection direction-indicating device and bicycle equipped with the saddle

A bicycle including a saddle having a base plate and a saddle body supported on the base plate, the saddle being mounted to a seat post of the bicycle, said saddle body having a recessed receiving space formed inside the saddle body at a rear portion of the saddle, wherein the bicycle is provided with a laser projection direction-indicating device, the laser projection direction-indicating device comprising:

• a module housing inserted in flush manner within the recessed receiving space of the saddle body, thereby the module housing being substantially isolated from an external environment, and a left laser projection port and a right laser projection port are formed on the module housing to project in a direction away from the module housing and through the recessed receiving space;
• a left laser element disposed in the left laser projection port of the module housing;
• a right laser element disposed in the right laser projection port of the module housing;
• a control unit mounted inside the module housing and connected with the left laser element and the right laser element, wherein the control unit is fully enclosed within the saddle body of the saddle;
• and
• a direction signal generation unit connected with the control unit and operable to selectively generate either one of a left turn signal or a right turn signal, the left turn signal and the right turn signal being selectively sent by the direction signal generation unit to the control unit;
• wherein upon receiving the left turn signal, the control unit responsively generates a left-turning driving signal to thereby drive the left laser element to generate a left-side laser projection pattern, the left-side laser projection pattern being projected towards a ground surface at a predetermined distance from a left side of the bicycle;
• and
• wherein upon receiving the right turn signal, the control unit responsively generates a right-turning driving signal to thereby drive the right laser element to generate a right-side laser projection pattern, the right-side laser projection pattern being projected towards a ground surface at a predetermined distance from a right side of the bicycle.
