New description: [New technical field] This is a kind of bicycle power generation device, especially one that drives the gear of the power generation device to generate electric energy when the bicycle is traveling, and can store the gear by linear motion of the chain. It is used in the battery for the lighting unit or peripheral electronic products. [Prior Art] According to the global warming and energy reduction, energy conservation and carbon reduction have become the goal of the world. The "bicycle" has become the most popular means of transportation because it is light and environmentally friendly and can be used as a sports and fitness tool. After pressing, since bicycles are a kind of light vehicles, the necessary lighting devices for steam locomotives are always paid for. However, in recent years, the proportion of bicycle traffic accidents has increased day by day. According to the investigation, the main reason is the lack of bicycles. Active lighting and warning devices cause them to be neglected by the locomotives during the journey, and accidents such as collisions occur. Therefore, in order to improve driving safety, the Ministry of Communications has stipulated that bicycles must be equipped with active lighting equipment. However, there are many different ways to use the active lighting equipment currently used in bicycles. They are explained as follows: 1. The most common system is to have a battery inside, or to lock the card directly with the lighting device of the mains charging. On the front frame of the bicycle or the rear frame, the switch is controlled by the switch on the light-emitting device to control the ΟΝ/OFF or flashing of the light; however, if the battery is used as the power source, the battery must be replaced frequently during use, which not only costs High and does not meet environmental protection needs. Furthermore, if the illuminating device is charged by the commercial power supply, the -3- M373312 is not convenient to use, so it is not practical. Second, another method uses the bicycle to travel as a power source for power generation, which is connected to a driving wheel outside the small generator, and the driving wheel is used to abut the tire or the shaft of the telecentric to the tire. Or the revolving motion of the heavenly heart drives the driving wheel of the generator to rotate. However, it is checked that the driving wheel of the generator is in contact with the tire, and the driving wheel is driven by friction. This is easy to cause friction and reduce the service life of the tire. In addition, by using a driving wheel on the shaft of the Tianxin, and then driving the wheel to drive the driving wheel of the generator, it is necessary to add a driving wheel on the center of the sky, so the assembly is complicated, which is not conducive to the user DIY; The driving wheel installed in Tianxin is limited by the space, so the diameter cannot be too large, so that the rotation speed ratio cannot be improved, resulting in poor power generation efficiency and lack of it. [New content] The main purpose of this creation is to provide a bicycle power generation device that utilizes the linear displacement of the chain when the bicycle travels, and then drives a driving gear that is coupled with it to rotate, thereby driving the generator to generate electric energy. The electric energy can be stored in the electric storage unit, and the illuminating unit or the external electronic product can be connected and used to achieve the self-power supply effect. Another object of the present invention is to provide a bicycle power generating device which is designed to be user-friendly (DIY) and has an improved assembly efficiency. A further object of the present invention is to provide a bicycle power generating device which is driven by a linear displacement of a chain, so that when the user steps on a revolution, the chain can drive the number of rotations of the driving gear Ten laps, with improved efficiency in power generation efficiency. M373312 For the above purposes, the technical means adopted in this creation include: a bicycle, with a frame, front and rear wheels, a stepping unit and a transmission chain; characterized in that: the transmission chain is combined with an active power generation unit, The utility model comprises: a casing, wherein a small generator is arranged, the bottom edge is provided with a slot, a driving gear, and the wide distance of the tooth portion is matched with the pitch of the transmission chain, and the button is Mounted in the housing, only partially protruding the notch, coupled to the transmission chain, a gear set is disposed in the housing, which is driven by the driving gear, thereby driving the small generator Operating to generate electrical energy; a fixed frame, the lower end portion of which is locked on the bicycle frame by a positioning piece, and the upper end portion is positioned for the housing so that the driving gear can be accurately located in the bicycle transmission An electric storage unit is electrically connected to the small generator by a first cable, and has a casing and a battery for storing electric energy generated by the small generator; Emitting means electrically connected to the system storage unit.
