Description

Technical Field

[0001] The present invention belongs to the technical field of fitness equipment, and in particular to a fitness equipment with a compact drive module. Background Art

[0002] With the continuous improvement of people's health awareness, fitness equipment is more and more widely used in families and gyms. Many fitness equipment are equipped with drive devices to drive users to exercise. For example, a treadmill, as a common fitness equipment, is a necessary fitness equipment in families and gyms, and it is also the simplest one among current home fitness equipment, and is the best choice for home fitness equipment.

[0003] Traditional treadmills are composed of a motor and a transfer mechanism. The motor serves as a power source to provide power for the treadmill, and the transfer mechanism is responsible for transmitting the driving force of the motor to the treadmill belt to achieve the movement of the running belt. However, this traditional drive structure has some problems. First, the combination of the motor and the transfer mechanism results in a relatively large occupied space for the drive structure. Since the motor is usually installed at the front end of the running platform, a large amount of space at the front end of the running platform is occupied, restricting the installation space for other accessories. In addition, in order to protect the motor and the transfer mechanism, the size of the front protective cover also needs to be increased, which not only increases the volume of the treadmill but also leads to an increase in production and transportation costs. Summary of the Invention

[0004] In view of this, the present invention provides a fitness equipment with a compact drive module that can save installation space to meet industrial requirements.

[0005] A fitness equipment with a compact drive module includes a drive shaft, a drive device disposed on one side of the drive shaft, and a belt connected between the drive shaft and the drive device.

[0023] It should be noted that the fitness equipment can be a treadmill, a stair climber, an elliptical machine, etc., and these devices all include a track driven by a motor. When people stand on the track, in order to keep their positions unchanged, they must walk or run in the direction opposite to the movement direction of the track, so as to achieve the purpose of fitness.

[0024] The drive shaft 1 is used to transmit the power generated by the drive device 2 to the track, so as to drive the track to move. It can be imagined that the drive shaft 1 can be mounted on a frame, and the drive shaft 1 is slidably connected to both sides of the frame through a bearing respectively.
