Description

Technical Field

[0001] This invention relates to a pedal power connection structure for a treadmill. Background Technology

[0002] Treadmills are leg exercise devices primarily designed to simulate the leg movements of climbing stairs and mountains. Traditional treadmills use hydraulic actuators for force control, offering multiple intensity levels to create different exercise conditions. Users simply need to hold the handles naturally and pedal. However, this type of treadmill has limited functionality and cannot meet the daily needs of users. To address this issue, we designed a multi-functional treadmill with massage and heating functions on the pedals, requiring a corresponding electrical connection. Summary of the Invention

The treadmill body has an installation cavity. The drive mechanism includes a drive motor, a drive gear, and a drive linkage. The drive gear connects to the drive motor and the drive linkage. The drive linkage is located on the left and right sides of the treadmill body, and each drive linkage connects to one end of the foot pedal. The other end of the foot pedal has a roller. The drive mechanism drives the foot pedal to move in a forward and backward direction. A circuit board is installed in the installation cavity. A massage mechanism is installed on the foot pedal. The circuit board is electrically connected to the drive motor and the massage mechanism. A first electrical contact block and a second electrical contact block are provided on the drive linkage. A first electrical contact portion and a second electrical contact portion are provided on the foot pedal drive rod. The first electrical contact portion and the first electrical contact block cooperate, and the second electrical contact portion and the second electrical contact block cooperate.
