摘要： An inertial measurement unit (IMU) device includes a circuit board assembly including a rigid circuit board and a flexible circuit board, an IMU sensor disposed on the rigid circuit board, and a heat preservation system. The IMU sensor is electrically connected to an external element through the flexible circuit board to transmit at least one of a signal or power between the IMU sensor and the external element. The heat preservation system includes a heat source, a heat preservation body with a receiving space to accommodate the IMU sensor, and a heat conductive member configured to transfer heat from the heat source to the IMU sensor to maintain the IMU sensor at a preset temperature. The heat conductive member includes an electrically insulating and thermally conductive silicone.

摘要： 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.
