    Abstract: The present disclosure is for a bicycle pedaling frequency sensor comprising a signal acquisition unit, a data transmission unit, and/or a data conversion unit. Pedaling frequency is obtained by recording and converting periodical changes of acceleration and/or of angular velocity in real time. This can be achieved by further incorporating a two axis, a three axis acceleration sensors, and/or gyroscope sensors. The pedaling frequency sensor communicates wirelessly with a computing terminal. It is powered and housed within the cavity of a shell, wherein the shell's outer surface is in thread fit with an inner surface of an expansion component. The expansion component allows the sensor to be inserted into and secured within hollow spaces on a bicycle's pedals and/or cranks.

    Abstract: The invention discloses a bicycle pedaling frequency sensor, comprising a signal acquisition unit arranged on a circuit board and used for acquiring motion acceleration changes and/or angular velocity changes in different rotation directions of a middle axle in real time, a data transmission unit for transmitting the acquired data to a terminal, and a power supply for supplying power to each unit to work. When in use, the pedaling frequency sensor is fixed on the hollow middle axle of a bicycle, and the middle axle, a crank and pedals of the bicycle rotate synchronously; during riding motion, acceleration change and/or angular velocity change data is acquired in real time and transmitted to the corresponding processing terminal via the data transmission unit for processing, real-time rotating frequency of the middle axle of the bicycle is obtained, and then pedaling frequency data during riding is acquired. Because the pedaling frequency sensor skillfully implements counting through periodical changes of acceleration or/and angular velocity data and other data when the bicycle moves and does not need to carry out counting in a sensing mode through periodical relative motion between two separated components, the pedaling frequency sensor is simple in structure, small in size and works stably and reliably.

    Abstract: The present invention is applicable to the field of bicycle motion protection and safeguard equipment. The present invention discloses a light emitting helmet, including a helmet main body and a light emitting lamp band, a fixing groove is formed in the surface of the helmet main body, a through hole is formed in the fixing groove, the light emitting lamp band is provided with a control line, the light emitting lamp band is fixed in the fixing groove through a fixing mechanism, and when the light emitting lamp band is fixed, the control line is in signal connection with a controller by penetrating through the through hole. As the light emitting lamp band is fixed in the fixing groove, the control line of the light emitting lamp band forms the signal connection with the controller by penetrating through the through hole. Even if damage occurs, the light emitting lamp band can be singly repaired in the production process, thereby avoiding the problems that the light emitting lamp band arranged in the helmet main body cannot be repaired when a fault occurs, and that arrangement of the lead of the light emitting lamp band is complex in the forming process, and reducing the production cost and the forming difficulty of the light emitting helmet.
