[0002] With the increasing awareness of health, fitness equipment is being used more and more widely in homes and gyms. Many fitness equipment are equipped with drive devices to help users exercise, such as treadmills. As a common type of fitness equipment, treadmills are a staple in homes and gyms, and are the simplest type of home fitness equipment today, making them the best choice for home fitness equipment.

[0003] Traditional treadmills consist of a motor and a transmission mechanism. The motor acts as the power source, providing power to the treadmill, while the transmission mechanism is responsible for transmitting the motor's driving force to the treadmill belt, thus enabling the belt to move. However, this traditional drive structure has several problems. First, the combination of the motor and transmission mechanism results in the drive structure occupying a significant amount of space. Since the motor is usually mounted at the front of the running platform, this occupies a large portion of the front space, limiting the installation space for other components. Furthermore, to protect the motor and transmission mechanism, the size of the front protective cover also needs to be increased, which not only increases the size of the treadmill but also leads to higher production and transportation costs.
