Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, specifically an elliptical car with manually adjustable track slope. Background Technology

[0002] Currently, most elliptical bikes use a motor to drive the track up and down, thereby changing the movement trajectory and meeting the fitness needs of different users.

[0003] However, the motor-driven structure requires matching control components, which are susceptible to voltage fluctuations or component aging, resulting in a high risk of failure and difficult maintenance. This not only affects the user experience but also limits the use of elliptical bikes in damp, dusty, or unreliable locations such as outdoor gyms and basements. Meanwhile, the older manual track adjustment mechanism is difficult and time-consuming to adjust.

[0004] In addition, the high cost of motors and their components keeps the overall cost of elliptical bikes high, limiting their popularity in the low-to-mid-end market and among home users.

[0005] Therefore, it is necessary to design an elliptical train with manually adjustable track incline, which can quickly adjust the track incline in multiple levels manually to meet the fitness needs of different exercise intensities, reduce costs, and meet diverse market demands and application scenarios. Summary of the Invention

[0006] To overcome the shortcomings of the prior art, this utility model provides an elliptical bike with manually adjustable track incline. It enables rapid adjustment of the track incline in multiple levels through manual means, meeting the fitness needs of different exercise intensities, reducing costs, and satisfying diverse market demands and application scenarios.

[0007] To achieve the above objectives, this utility model designs an elliptical cart with manually adjustable track slope, comprising a frame, an adjusting sleeve, an adjusting tube, a pneumatic cylinder, a pin, a lifting rod, rollers, a lifting mechanism, a track, a transmission rod, a crank, a large flywheel, pedals, a support rod, and a movable handle. The adjusting sleeve is installed inside the frame, with one end rotatably connected to the frame. A pneumatic cylinder is installed inside the adjusting sleeve, and the other end of the adjusting sleeve is fitted over the adjusting tube. The piston rod of the pneumatic cylinder is connected to the adjusting tube. A pin is installed at the top of the adjusting sleeve, with the end of the pin passing through the adjusting sleeve and the adjusting tube. The end of the adjusting tube is connected to one end of the lifting rod. The lifting mechanism is rotatably connected to the adjusting tube and the lifting rod. Roller 1 is installed in the slide rail on the side of the frame. The other end of the lifting rod is rotatably connected to the connecting piece on the side of the lifting mechanism. The end of the lifting mechanism is rotatably connected to the frame. The top of the lifting mechanism is equipped with a track. Roller 2 at the end of the transmission rod is slidably connected to the track. The other end of the transmission rod is connected to the connecting rod of the crank. The center of the crank is coaxial with the center of the large flywheel. The middle part of the transmission rod is rotatably connected to the end of the pedal. The side of the pedal is connected to one end of the support rod. The other end of the support rod is connected to the bottom of the movable handle. The middle part of the movable handle is rotatably mounted on the frame.

[0008] The crank and the large flywheel are mounted on a rotating shaft one. The rotating shaft one and the rotating shaft two are connected by a transmission belt. A small flywheel is installed at the end of the rotating shaft two. The small flywheel is connected to the motor shaft of the self-generator by a multi-tight belt. The power output terminal of the self-generator is connected to the power input terminal of the instrument.

[0009] The self-generator is fixed to the end of the frame, and a pressure wheel frame is installed on the side of the self-generator.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figure 1 As shown, this utility model is an elliptical cart with manually adjustable track slope, including a frame, an adjusting sleeve 16, an adjusting tube, a pneumatic cylinder, a pin, a lifting rod, rollers, a lifting mechanism, a track, a transmission rod, a crank, a large flywheel, pedals, a support rod, and a movable handle. The adjusting sleeve 16 is installed inside the frame 10, and its end is rotatably connected to the frame 10. A pneumatic cylinder 23 is installed inside the adjusting sleeve 16, and its other end is sleeved on the adjusting tube 24. The piston rod of the pneumatic cylinder 23 is connected to the adjusting tube 24. A pin 15 is installed on the top of the adjusting sleeve 16, and its end passes through the adjusting sleeve 16 and the adjusting tube 24. The end of the adjusting tube 24 is rotatably connected to one end of the lifting rod 17. A roller 19 is provided at the connection between the tube 24 and the lifting rod 17. The roller 19 is installed in the slide rail on the side of the frame 10. The other end of the lifting rod 17 is rotatably connected to the connecting piece on the side of the lifting mechanism 18. The end of the lifting mechanism 18 is rotatably connected to the frame 10. The top of the lifting mechanism 18 is provided with a track 21. The roller 20 at the end of the transmission rod 4 is slidably connected to the track 21. The other end of the transmission rod 4 is connected to the connecting rod of the crank 6. The center of the crank 6 is coaxial with the center of the large flywheel. The middle part of the transmission rod 4 is rotatably connected to the end of the pedal 14. The side of the pedal 14 is connected to one end of the support rod 13. The other end of the support rod 13 is connected to the bottom end of the movable handle 2. The middle part of the movable handle 2 is rotatably installed on the frame 10.

[0020] Preferably, crank 6 and the large flywheel are mounted on rotating shaft one. Rotating shaft one and rotating shaft two 12 are connected by a transmission belt. A small flywheel 11 is installed at the end of rotating shaft two 12. The small flywheel 11 is connected to the motor shaft of the self-generator 7 by a multi-belt 8. The power output terminal of the self-generator 7 is connected to the power input terminal of instrument 1 to supply power to instrument 1. Instrument 1 allows technicians or customers to intuitively understand information such as the heat consumed during use, the usage time, and the slope of the lifting track 21.

[0021] The generator 7 is fixed to the end of the frame 10, and a pressure wheel frame 9 is installed on the side of the generator 7 to increase the tension.

[0022] Instrument 1 is mounted on the top of frame 10. Fixed handles 3 are mounted on both sides below instrument 1, providing users with static grip points and enhancing safety and stability during movement. A drive board 22 is also mounted on frame 10, which centralizes electronic components for easy maintenance by technicians.

[0023] Frame 10 includes an upper frame and a lower frame.

[0024] During the use of this utility model, see Figure 2 When the slope of track 21 needs to be increased, the piston rod of the pneumatic cylinder 23 extends, causing the adjusting tube 24 to extend out of the adjusting tube sleeve 16. Roller 19 slides along the slide rail towards the tail of the frame 10. The lifting rod 17 rotates counterclockwise with the connection point of the connecting piece as the center, and the lifting mechanism 18 is lifted. The track 21 at the top of the lifting mechanism 18 also increases in slope accordingly. After adjustment, the pin 15 is inserted into the pin holes of the adjusting tube sleeve 16 and the adjusting tube 24 to fix the relative positions of the adjusting tube sleeve 16 and the adjusting tube 24.

[0025] See Figure 2 When the slope of track 21 needs to be reduced, the piston rod of pneumatic cylinder 23 retracts, causing adjusting tube 24 to retract adjusting tube sleeve 16. Roller 19 slides along the slide towards the head of frame 10, and lifting rod 17 rotates clockwise around the connection point of connecting piece, lowering lifting mechanism 18. The slope of track 21 at the top of lifting mechanism 18 is also reduced accordingly. After adjustment, pin 15 is inserted into the pin holes of adjusting tube sleeve 16 and adjusting tube 24 to fix the relative position of adjusting tube sleeve 16 and adjusting tube 24. This utility model achieves better hip force by adjusting the starting height of pedal 14 when it is stepped on, thereby changing the movement trajectory.

[0026] The user places one foot in front of the other on the left and right pedals 14, and holds the corresponding movable handles 2 with both hands. By stepping on the pedals 14, the user drives the corresponding transmission rod 4, and by pushing and pulling the movable handles 2 with both arms, the transmission rod 4 moves back and forth in a crisscross motion. Alternatively, the user can hold the corresponding fixed handles 3 with both hands to move the rod. The transmission rod 4 drives the large flywheel through the crank 6, and transmits the power to the small flywheel 11 through the first rotating shaft, the transmission belt, and the second rotating shaft 12. The flywheel 11 is then driven by the multi-belt 8 to power the generator 7, which in turn supplies power to the instrument 1.

[0027] After testing, the results showed that this invention and the elliptical bike with motor-driven adjustable foot pedal incline provide the same effect on exercising the thigh and gluteal muscles.

[0028] This invention, through the coordinated operation of the lifting mechanism and the pneumatic cylinder, can quickly and accurately adjust the track slope to achieve different training intensities in different training scenarios such as climbing slopes and flat ground, meeting the fitness needs of different exercise intensities; it provides a more economical and practical choice of exercise equipment, improves the user experience, and meets diverse market demands and application scenarios.
