For example, the existing bicycles are installed for driving at night. In order to prevent getting lost in the field, the GPS installed; the mobile power supply provided for MP3 and other electronic devices, in order to realize the above functions, a larger storage battery is required to realize the following problems: 1. There is no Use new energy to achieve the purpose of energy saving and environmental protection; 2. In order to achieve long-term battery life, the battery is large in size and weight, which is not easy to carry; 3. It is impossible to supply power to electronic equipment outdoors or when it is disconnected from the power supply for a long time. It is inconvenient for people to use it.

SUMMARY OF THE INVENTION The purpose of this utility model is to address the deficiencies in the prior art and provide a self-powered multifunctional bicycle based on piezoelectricity, so that the piezoelectric energy can be used to power the bicycle when riding away from the power supply for a long time Power supply for various electronic devices, realize various functions such as car lighting, GPS navigation, MP3 music playback, electric gloves and hand warming, etc. It has the advantages of energy saving, environmental protection, practicality and strong fun.

The utility model is composed of a bicycle, a piezoelectric material, a storage battery, a miniature GPS navigator, a USB interface module, an electric heating glove and an LED lighting lamp. The piezoelectric material adopts an organic piezoelectric film, and the organic piezoelectric film is installed on In the front and rear tires of the bicycle, the electrode leads are connected to the axle along the spokes, and then the leads from the axle are connected to the input end of the piezoelectric energy harvesting circuit board, and the output end of the circuit board is connected to the battery. The battery and the USB interface module are installed on the handlebar Inside, electric heating gloves and a miniature GPS navigator are installed on the handlebar, and LED lights are installed on the front end of the bicycle; the piezoelectric energy harvesting circuit board includes a power conditioning circuit module, a DC-DC circuit module and a supercapacitor.

The USB module, the electric heating gloves and the micro GPS are connected to the storage battery through wires; the USB interface module is a mobile device charging interface and an MP3 player interface; the LED lighting is connected to the storage battery through a switch circuit; The electric heating gloves are detachable.

After adopting the above structure, during the riding process, the piezoelectric film is mechanically deformed to generate a large amount of electric charges. The piezo film electrodes are connected to a piezo energy harvesting circuit, which collects the charge and charges the battery. The storage battery is connected with various electronic devices to supply power to them, and can also charge mobile phones, MP3 and other devices through the USB interface.

The beneficial effects of the utility model are: in the case of long-distance riding, the utility model can use the piezoelectric energy to charge the storage battery, thereby supplying the electronic equipment installed on the bicycle, and can charge the mobile phone, MP3, etc. It has the ability of self-power supply. And compared with the existing technology, installing a miniature GPS navigator can prevent getting lost in long-distance riding; installing a USB interface to charge mobile phones, MP3 and other devices can increase the fun of riding; installing electric heating gloves can prevent long-distance riding in winter The cold during driving; the installation of LED lighting provides the possibility for night riding. The utility model has the advantages of energy saving, environmental protection, powerful function and self-power supply.
