DETAILED DESCRIPTION

[0028] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0029] like Figure 1-3 As shown, a self-generating elliptical machine includes a base 100 for placement on a horizontal surface and a frame 200 connected to the base 100. The frame 200 is a vertically upward tubular structure with a control panel 300 connected to its top. The control panel 300 is symmetrically connected to first handles 400 on either side. Connectors 500 are rotatably connected to opposite sides of the middle portion of the frame 200. Pedal structures 600 are connected to the opposite outer sides of the two connectors 500. By alternately stepping on the pedal structures 600 up and down, the connectors 500 rotate relative to the connection with the frame 200, achieving a pedaling motion of the driving pedal structures 600 of the connectors 500. Preferably, the upper half of the connector 500 is connected to the frame 200, and the lower half is connected to the pedal structure 600. A driving pulley 700 is connected between the connector 500 and the frame 200 on one side. The driving pulley 700 is connected to a magnetically controlled pulley 800 via a belt. The magnetically controlled pulley 800 is coaxially connected to a driven pulley 900. Preferably, the circumference of the driven wheel 900 is smaller than the circumference of the magnetic control wheel 800. The frame 200 is a telescopic structure, and the height of the frame 200 can be adjusted according to the height of the user, making it suitable for people of various heights to operate the control panel 300, thereby improving its wide applicability. By alternately stepping on the pedal structure 600, the driving wheel 700 rotates, and the rotational motion is transmitted to the magnetic control wheel 800 through the belt, and then rotates together with the coaxial driven wheel 900 to realize the movement of the whole machine. The control panel 300 can be provided with a display screen for easy observation of exercise parameters, and can also play music or videos, etc., to make the exercise process less boring. A cup placement cavity can also be provided in the upper part of the frame 200, which is convenient for drinking water during exercise, providing convenience to the user.

[0030] The rocker arm of the pedal structure 600, after connecting to the connector 500, extends upward to form a second handle 610. The second handle 610 is pivotally connected to the upper portion of the frame 200 via a pivoting member. This not only defines the longitudinal position of the second handle 610 but also allows it to swing with the pedal structure 600. The pivoting member can be a rotating shaft, a rotating pin, or a rotating rod. The dual-handle configuration allows users to choose to hold either the first handle 400 or the second handle 610, providing multiple options to accommodate users with varying needs.

[0031] Specifically, driven wheel 900 is connected to the input shaft of brushless generator 1000 via a belt. The brushless generator 1000 is secured to base 100 via a fixing member. Driven wheel 900 rotates, transmitting power to brushless generator 1000, causing it to generate electricity. Controller 1300, electrically connected to brushless generator 1000, is also mounted on frame 200. Brushless generator 1000 supplies power to controller 1300, which is electrically connected to it. Controller 1300 is then electrically connected to a hollow rotary encoder 310 mounted on control panel 300, enabling self-generated power.

[0032] The first handle 400 or the second handle 610 is provided with a damping adjustment button 1100 electrically connected to the hollow rotary encoder 310. The damping adjustment button 1100 is a toggle button for increasing or decreasing the damping. When used in a liftable elliptical machine, an angle adjustment button 1200 can be provided on the other side handle. The angle adjustment button 1200 is a toggle button for increasing or decreasing the angle. The first handle 400 or the second handle 610 can also be provided with a heart rate monitoring unit electrically connected to the hollow rotary encoder 310 for monitoring the user's real-time heart rate and transmitting the data to the mobile terminal APP 1600, which will be described in detail below.

[0033] In this embodiment, the controller 1300 is connected to a lithium battery 1400, which is used to store the electricity generated by the brushless generator 1000. The electricity is used to power the training vehicle to start, allowing it to be used without being plugged in. The base 100 is also connected to a resistance motor 1500 that adjusts the training resistance of the training vehicle. The controller 1300 is electrically connected to the resistance motor 1500. The elliptical machine relies on the electricity in the lithium battery 1400 to start. As the pedals of the pedal structure 600 are continuously stepped on, the wheel transmission movement drives the brushless generator 1000 to generate electricity, continuously supplying the components that need electricity, allowing riding without plugging in a power cord. The controller 1300 also has a power socket for plugging in an external power supply. This realizes the dual power supply mode of the elliptical machine.

[0034] The angle increase toggle button, resistance increase toggle button, angle decrease toggle button, and resistance decrease toggle button are electrically connected to the hollow rotary encoder 310. When the corresponding button is toggled, the hollow rotary encoder 310 transmits a signal to the controller 1300, which then transmits the signal to the corresponding resistance motor 1500 to change the damping.

[0035] In this embodiment, the mobile terminal app 1600 is wirelessly connected to the adjustment button or hollow rotary encoder 310. This allows for resistance adjustment via the mobile terminal app 1600. For use with a liftable elliptical trainer, the angle can also be adjusted. Bluetooth is preferred for wireless connection.

[0036] In order to facilitate the movement of the training vehicle, a pulley 1700 is set on the end face of the base 100. When the elliptical machine is in use, there is a gap between the bottom of the outer peripheral surface of the pulley 1700 and the horizontal plane. When not in use, the rear side of the base 100 is raised, and the pulley 1700 contacts and slides on the ground and is moved to the desired position, which is easy to carry and saves time and effort.

[0037] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed for the present invention is defined by the appended claims and their equivalents.
