Description

Technical Field

[0001] The utility model relates to the field of fitness, in particular to an elliptical machine. Background Art

[0002] Chinese patent document with publication number CN118236671A discloses a waist-twisting stepper, which includes a bottom plate and a movable plate rotatably arranged on the bottom plate. Two pedals capable of reciprocatingly swinging are movably arranged on the movable plate. The pedals are movably arranged on the movable plate through eccentric wheels. A driving mechanism for driving the eccentric wheels to rotate is arranged on the movable plate. The driving mechanism drives the movable plate to reciprocate horizontally through a transmission mechanism. A housing is buckled on the bottom plate. A display panel for displaying speed is arranged on the housing. The housing is buckled above the bottom plate and the driving mechanism. The speed of the driving mechanism is adjusted through a controller to adjust the gear, and data information is displayed through the display panel. The controller can be adjusted through a remote control. The operation is relatively convenient. The whole machine is started by the remote control or the physical buttons on the display panel, and the speed is adjusted by the remote control or the physical buttons to realize more exercise modes. A fork for driving the second bevel gear to move along the length direction of the driving shaft is arranged in the housing. After the second bevel gear is driven by the fork to move, it meshes with or disengages from the first bevel gear, so that the stepper can perform the stepping function alone or twist while stepping.

[0003] In the above solution, the gear can be adjusted by adjusting the speed of the driving mechanism through the controller, but the usage process of the user cannot be counted, and the user cannot intuitively feel the exercise data. Moreover, only the kinetic energy is transmitted through the first bevel gear and the second bevel gear. In this way, when assembling the motor, it is necessary to consider whether the kinetic energy provided by the motor can meet the requirement of driving the movable plate. When using a high-power motor, the cost will undoubtedly increase. When using an ordinary motor, the stepper may not be fully driven to operate. Therefore, there is still a large room for improvement in this stepper. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an elliptical machine with reasonable structure and counting function.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] An elliptical machine includes two foot pedals and a power mechanism for providing power to the two foot pedals. It is characterized in that it further includes a counting mechanism. The power mechanism includes a power shaft, a gearbox, a motor, and a transmission mechanism. The front end of the output shaft of the motor extends into the gearbox, and the transmission mechanism is arranged in the gearbox to realize the transmission connection between the output shaft and the power shaft. The counting mechanism includes a counter, a Hall sensor, and a magnet. The magnet is eccentrically arranged at the rear end of the output shaft of the motor. The Hall sensor can sense the position change signal of the magnet and feedback it to the counter, and the counter generates exercise data according to the signal feedback by the Hall sensor.

[0007] By adopting the above scheme, during use, the Hall sensor in the counting mechanism can sense the magnet, and the sensed result is output and feedback to the counter. The counter can generate corresponding exercise data according to the output result, so as to facilitate recording the exercise times of the user, enabling the user to accurately formulate a training plan according to their own situation.

[0008] The motor is fixedly arranged outside the gearbox, and a housing is fixedly arranged outside the motor. The Hall sensor is arranged on the housing.

[0009] By adopting the above scheme, arranging a housing outside the motor can facilitate the assembly of the Hall sensor, and arranging the motor outside the gearbox can make better use of the space.

[0010] A mounting seat is fixedly arranged at the rear end of the output shaft of the motor. At least one mounting hole is arranged on the end face of the mounting seat, and the magnet is arranged in the mounting hole.

[0011] By adopting the above scheme, during installation, only by placing the magnet in the mounting hole, the assembly of the magnet can be completed, which can make the assembly of the magnet more convenient.

[0012] The housing includes an annular side plate and a rear end plate. The annular side plate surrounds the outer peripheral surface of the motor, and the rear end plate is arranged opposite to the rear end of the motor at an interval and closes the rear port of the annular side plate.

[0013] By adopting the above scheme, surrounding the motor in the annular side plate can facilitate the assembly of the motor. The rear end plate is arranged opposite to the rear end of the motor at an interval and closes the rear port of the annular side plate, which can prevent foreign objects from entering the motor.

[0014] The housing is divided into two half shells along its central axis. One side of the two half shells is connected to each other, and the other side is connected to each other by fasteners so that the two half shells are clamped on the outer peripheral surface of the motor.

[0015] By adopting the above - mentioned solution, the housing is divided into two half - shells along the central axis, and one side of the two half - shells is connected to each other. In this way, when assembling the motor, the motor can be simply installed from the other side of the two half - shells and locked with fasteners, which greatly facilitates the assembly of the motor.

[0016] A circuit board for carrying the Hall sensor is arranged on the outer side of the rear end plate.

[0017] By adopting the above - mentioned solution, arranging a circuit board for carrying the Hall sensor on the outer side of the rear end can save space and increase the accuracy of the Hall sensor.

[0018] The front end face of the motor is locked to the gearbox by bolts.

[0019] By adopting the above - mentioned solution, the position of the motor can be further fixed to prevent the motor from displacing during use.

[0020] The power shaft is rotatably arranged on the gearbox through a first bearing, and both ends of the power shaft extend outward from both sides of the gearbox. The two foot - stepping components are respectively connected to both ends of the power shaft through a first rod and a second rod. One end of the first rod is connected to the power shaft, and the other end is connected to the second rod, and the second rod is perpendicular to the first rod. The transmission mechanism includes a worm wheel, a worm, a first gear, and a second gear. The worm is fixedly arranged on the output shaft of the motor, the worm wheel is rotatably arranged in the gearbox and meshes with the worm, the first gear is coaxially arranged with and connected to the worm wheel, and the second gear is fixedly arranged on the power shaft and meshes with the first gear.

[0021] By adopting the above - mentioned solution, when in use, the motor drives the worm wheel and the worm, and the kinetic energy is transmitted from the first gear and the second gear to the first rod and the second rod to drive the foot - stepping component by the second rod. In this way, only a relatively ordinary motor can be used to achieve the effect of driving the foot - stepping component, which will undoubtedly greatly save costs.

[0022] The worm wheel and the worm are in non - self - locking meshing.

[0023] By adopting the above - mentioned solution, the worm wheel and the worm can operate more smoothly, avoiding the self - locking of the turbine and the worm when rotating in the reverse direction, which may cause the elliptical machine to malfunction.

[0024] The diameter of the first gear is smaller than that of the second gear.

[0025] By adopting the above - mentioned solution, the transmission ratio between the first gear and the second gear can be increased to reduce the rotational speed of the first gear, making it more suitable for the exercise rhythm of the user.

[0026] The gearbox includes two side plates that are parallel and spaced relatively, and an enclosing plate connected between the two side plates. The power shaft is rotatably supported on the two side plates through two first bearings.

[0027] By adopting the above scheme, the gearbox is arranged between the two side plates, and the power shaft is rotatably supported on the two side plates through two first bearings, which can facilitate the fixing and installation of the gearbox.

[0028] It further includes a frame. The frame includes a main beam extending forward and backward. Two mounting plates are arranged in parallel and spaced on the top of the main beam. The gearbox is located between the two mounting plates, and the two side plates are respectively locked and fixed to the two mounting plates through fasteners.

[0029] By adopting the above scheme, the gearbox is locked and fixed to the frame through the two side plates and the two mounting plates respectively through fasteners, which can make the gearbox more stably fixed on the frame and also facilitate the installation of the gearbox.

[0040] The power mechanism 2 includes a motor 21, a power shaft 22, a gearbox 23, and a transmission mechanism 24. The front end of the output shaft 211 of the motor 21 extends into the gearbox 23. The gearbox 23 is formed with a limiting portion 235 adapted to the end of the output shaft 211 for restricting the end of the output shaft 211. The transmission mechanism 24 is disposed in the gearbox 23 for realizing the transmission connection between the output shaft 211 and the power shaft 22. A screw hole 212 is provided on the front end face of the motor 21. An installation surface 231 is formed on the contact surface of the gearbox 23 with the front end face of the motor 21. The motor 21 is fixed to the installation surface 231 of the gearbox 23 through a bolt 232 and the screw hole 212 and is located outside the gearbox 231. A housing 213 is disposed outside the motor 21. The housing 213 includes an annular side plate 214 and a rear end plate 215. The annular side plate 214 surrounds the outer peripheral surface of the motor 21.

The rear end plate 215 is disposed opposite to the rear end of the motor 21 at an interval and closes the rear port of the annular side plate 214. A wire passing hole 2143 is formed on the rear end face of the motor 21, and a heat dissipation hole 2144 is further formed on the rear end of the annular side plate 214. The annular side plate 214 is divided into two half shells along its central axis. One side of the two half shells can deform and rotate without being disassembled, and the other side is connected to each other through a locking member 2142 to clamp the two half shells around the outer peripheral surface of the motor 21.

The worm wheel 242 is rotatably arranged in the gearbox 23 and meshes with the worm 241. The first gear 243 is coaxially arranged with and connected to the worm wheel 242. The second gear 244 is fixedly arranged on the power shaft 22 and meshes with the first gear 243. The diameter of the first gear 243 is smaller than that of the second gear 244, and the worm wheel 242 and the worm 241 are in non-self-locking meshing. During use, the motor 21 outputs power to drive the worm 241 to rotate, and the worm 241 drives the worm wheel 242 to rotate. The worm wheel 242 is coaxially arranged with and connected to the first gear 243, and they rotate together, so that the first gear 243 drives the second gear 244 to rotate, and then drives the first rod 31 and the second rod 32 of the foot pedal part 3 to rotate through the power shaft 22, enabling the foot pedal part 3 to move under the drive of the motor 21. A second bearing 33 is also arranged between the front end of the foot pedal part 3 and the first rod 31, and a pulley 34 is arranged at the rear end of the foot pedal part 3. A chute 12 adapted to the pulley 34 is formed on the housing 1, which can make the rotation of the foot pedal part 3 smoother. One end of the first rod 31 connected to the power shaft 22 also forms two fixing rods 34. The two fixing rods 34 are arranged concentrically with the first rod 31 and are used to fix the circular dust cover 11 on the housing 1. The dust cover 11 can prevent foreign objects from entering the interior of the elliptical machine.

[0043] The counting mechanism 4 includes a counter 41, a Hall sensor 42 and a magnet 43. A mounting seat 216 is fixedly arranged at the rear end of the motor 22.

Two magnets 43 are respectively placed in the two mounting holes 217 and are fixed on the mounting seat 216 through a limiting plate 44. The Hall sensor 42 is fixed on the outside of the rear end plate 215. The Hall sensor 42 can sense the position change signal of the magnet 43 and feedback it to the counter 41 arranged on the housing 1. The counter 41 generates exercise data according to the signal feedback by the Hall sensor 42.

[0044] It further includes a frame 5 arranged in the housing 1. The frame 5 includes a main beam 51 extending forward and backward. Two parallel and spaced mounting plates 52 are arranged at the top of the main beam 51. The gearbox 23 is located between the two mounting plates 52. The two side plates 233 are respectively locked and fixed to the two mounting plates 52 through fasteners 53.

[0045] When in use, the user can first stand both feet on the two-foot pedals 3, and the counting mechanism 4 controls the motor 21 to start and drive the two-foot pedals 3 to move through the transmission mechanism 24. The Hall sensor 42 can monitor the position change signal of the magnet 43 arranged on the motor 21 and feedback it to the counter 41. The counter 41 generates exercise data according to the signal feedback by the Hall sensor 42 and displays it on the display screen of the counter 41.

[0046] The above are only the preferred embodiments of the present invention, and thus the scope of implementation of the present invention cannot be limited thereby. That is, equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the specification should still fall within the scope covered by the patent of the present invention.
