[0031] By setting the transmission assembly 8, which includes a housing 15, a gear transmission component 16 inside the housing 15, and a transmission motor 17, one end of the housing 15 is sleeved on the top of the screw 12 and hinged to the front end of the inclined pedal 6, the motor drives the gear transmission component 16 to drive the screw 12 to move, providing power for angle adjustment, and the housing 15 protects the internal components and extends the service life.

[0032] The gear transmission component 16 drives the transmission gear 13 to drive the screw 12 to move up and down along the sleeve 11 through the threaded interface 14.

[0033] By setting a gear transmission component 16 to drive the transmission gear 13, the screw 12 moves up and down along the sleeve 11 through the threaded interface 14. The screw 12 moves up and down along the sleeve through the rotation of the thread, realizing the flexible adjustment of the tilt pedal 6 angle. The operation is convenient and the adjustment accuracy is high.

[0034] The body 2 is provided with a rotating seat 18, which is hinged to the tail end of the tilting pedal 6.

[0035] By setting a rotating base 18 on the body 2, the rotating base 18 is hinged to the tail end of the tilt pedal 6, providing a stable rotation fulcrum for the tilt pedal 6, ensuring structural stability during angle adjustment and avoiding shaking.

[0036] A connecting rod 19 is provided between the rocker arm assembly 3 and the foot pedal assembly 4, and the two ends of the connecting rod 19 are respectively connected to the rocker arm assembly 3 and the foot pedal assembly 4.

[0037] By setting a connecting rod 19 between the rocker arm assembly 3 and the foot pedal assembly 4, with the two ends of the connecting rod 19 connecting the two respectively, the linkage movement of the rocker arm assembly 3 and the foot pedal assembly 4 is realized, making the movement trajectory more ergonomic and improving the comfort of exercise.

[0038] The foot pedal assembly 4 reciprocates along the guide groove 9 via the pulley 10.

[0039] By setting the foot pedal assembly 4 to reciprocate along the guide groove 9 via the pulley component 10, the frictional resistance during the movement is reduced, making the foot pedal action smoother, reducing exercise noise, and improving the user experience.

[0040] In this embodiment 2, like Figures 1 to 3 As shown, by setting up the elliptical machine body 1, the rocker arm assembly 3 at the front end of the machine body 2 and the foot pedal assembly 4 at the rear end are linked together, and the connecting rod 19 between the two achieves coordinated movement, improving the continuity of the movement; in the foot pedal adjustment assembly 5, the guide grooves 9 on both sides of the tilt pedal 6 cooperate with the pulley 10 to reduce friction and make the pedaling action smoother; the screw 12 assembly 7 and the transmission assembly 8 work together, and the transmission motor 17 drives the gear transmission component 16 to move the screw 12 up and down along the sleeve 11, precisely adjusting the angle of the tilt pedal 6 to meet the exercise intensity and posture needs of different users; the rotating seat 18 is hinged to the tail end of the tilt pedal 6, providing a stable fulcrum for the pedal angle adjustment and ensuring structural stability. The overall design takes into account the smoothness of the movement, the precision of the adjustment, and the adaptability of use, which can effectively improve the user's exercise experience and training effect.

[0041] In this embodiment 3, like Figures 1 to 3As shown, in this invention, the transmission motor 17 drives the gear transmission component 16 in the transmission assembly 8 to rotate. The gear transmission component 16 drives the transmission gear 13 of the screw 12 assembly 7 to rotate, causing the screw 12 to move up and down along the sleeve 11 through the threaded interface 14. Since the top of the screw 12 is hinged to the front end of the tilting pedal 6, the extension and retraction of the screw 12 directly pushes the tilting pedal 6 with the rotating seat 18 at the tail end as the fulcrum, realizing the precise adjustment of the tilt angle of the tilting pedal 6. Thus, the movement trajectory of the pedal assembly is adjusted by the tilt angle to achieve the user's desired exercise experience, meeting the needs of different users for exercise intensity and pedaling posture. During the exercise, the rocker arm assembly 3 and the foot pedal assembly 4 are linked by the connecting rod 19. When the user holds the rocker arm assembly 3 and swings it, the connecting rod 19 drives the foot pedal assembly 4 to move synchronously. The pulley component 10 at the bottom of the foot pedal assembly 4 slides back and forth along the guide grooves 9 on both sides of the tilting pedal 6, reducing frictional resistance while ensuring that the pedaling action and the rocker arm swing are coordinated and consistent, forming an ergonomic elliptical trajectory movement that simulates the smooth posture of natural walking and running.

[0042] In the overall structure, the mechanical cooperation of each component (such as the threaded transmission between the screw 12 and the sleeve 11, the sliding cooperation between the pulley and the guide groove 9, and the linkage of the connecting rod 19) ensures the stability of the equipment operation and the continuity of movement, which not only realizes the flexible angle adjustment of the tilting pedal 6, but also ensures the smooth experience of the user during movement.
