[0002] Treadmills are widely used as common fitness equipment. Current treadmills typically include an independent motor fixed to the bottom of the frame. The motor's output shaft drives the drive roller via a belt / gear, and the drive roller, in turn, drives the driven roller through friction with the running belt. The drawbacks of this structure are: 1. Too many transmission components, leading to energy loss during transmission; 2. Complex mechanical structure, resulting in high maintenance costs; 3. The motor occupies extra space, resulting in a bulky size; 4. Significant transmission noise. Utility Model Content

[0003] To solve the above-mentioned technical problems, a treadmill with a geared roller motor is provided.

[0010] According to this utility model, it further includes an adjustable tilt support component connected to the horizontal base. One end of the support component is connected to the running board. The support component can change the angle between the running board and the horizontal bottom surface by telescopic adjustment, thereby changing the tilt angle of the running board.

[0011] According to this utility model, the running belt is an anti-static running belt, and the wrap angle of the reduction roller motor is 220°-240°.

Detailed Implementation

[0024] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0025] like Figures 1 to 6 As shown in the embodiment of this application, a treadmill with a geared roller motor is disclosed, including a frame 100. The frame 100 includes a horizontal base 110 and an adjustable tilt support component 120 connected thereto. One end of the support component 120 is connected to the running board 310. The support component 120 can change the angle between the running board 310 and the horizontal bottom surface by telescopic adjustment, thereby changing the tilt angle of the running board 310 and changing the exercise intensity of the exerciser. The running platform assembly 300 includes the running board 310 and a running belt 320 disposed thereon. The running belt 320 is an anti-static running belt, which wraps the geared roller motor 200 in an Ω-shaped single-layer winding manner, with a wrap angle range of 220°-280°.

[0026] To increase the treadmill's starting torque while changing the inclination angle of the running board 310, a geared roller motor 200 is connected to one end of the horizontal base 110. The two ends of its roller shaft 210 are fixed to the side plates of the horizontal base 110, allowing it to be installed at either the front or rear end of the horizontal base 110. A traditional roller is installed at the other end of the horizontal base 110 opposite to the geared roller motor 200, driving the traditional roller to rotate. The geared roller motor 200 adjusts the reduction ratio, reducing the motor speed while amplifying the torque to meet the treadmill's torque requirements. The driver of the geared roller motor 200 is connected to an external control console (not shown in the figure) via a cable to drive the geared roller motor 200.

[0027] The geared roller motor 200, model DGBLA50A / 60A / 76, includes an external rotor motor, a planetary reducer, and a drive roller. Adjusting the reduction ratio of the planetary reducer increases torque, meeting the high torque requirements of the treadmill during startup. The geared roller motor 200 relies solely on low-voltage drive, reducing control system costs. Furthermore, due to the low inertia of the high-speed rotor in the geared roller motor, it facilitates rapid start-stop, shortening acceleration time and load change recovery time.

[0028] In this embodiment, an external rotor brushless motor is selected, the planetary reducer has a reduction ratio of 3:1-5:1, the drive roller is interference-fitted with the planetary reducer with an interference amount of 0.02-0.04mm, and the running belt has a 320° wrap angle of 240°. The planetary reducer's reduction ratio of 3:1-5:1 reduces the motor speed by 3-5 times while simultaneously amplifying the torque by 3-5 times, effectively improving the treadmill's instantaneous starting torque.

[0029] In this embodiment, a heat dissipation structure is also included, which is integrated on the frame 100 and is positioned corresponding to the geared roller motor 200. The heat dissipation structure includes a housing 400 with multiple microchannels, and a phase change material filling layer is provided inside, with a melting point of 45±2℃. Preferably, the phase change material is a paraffin or expanded graphite composite material, which absorbs or releases latent heat through a phase change process to achieve temperature regulation and energy management, and maintain a good heat dissipation effect.

[0030] In this embodiment, the support component 120 is an electrically adjustable telescopic rod. By adjusting the telescopic length of the rod, the tilt angle of the running board 310 is changed. Furthermore, the telescopic rod includes a first connecting part and a second connecting part connected by threads, which improves the adjustment accuracy of the running board's tilt angle.

[0031] In this embodiment, the running board 310 has a multi-layer composite structure, consisting of a glass fiber reinforced polyurethane layer 311, a honeycomb aluminum core 312, and a damping rubber layer 313 from top to bottom. The glass fiber reinforced polyurethane layer 311 has a thickness of 3±0.2mm, the honeycomb aluminum core 312 has a pore size of Φ5mm, and the damping rubber layer 313 has a loss factor ≥0.3. This design improves the running board's lifespan while enhancing its shock absorption effect, reducing vibration, and increasing exercise comfort.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
