[0020] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0022] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0023] The specific embodiments are as follows:

[0024] like Figure 1-3 The utility model provides an elliptical machine with a variable motion trajectory, comprising a frame 100, a pedal mechanism 200, a rotating mechanism 300, a swing arm rod 400, a crank 500 and a trajectory adjustment mechanism 600, wherein the pedal mechanism 200 comprises a pedal 210 and a pedal rod 220;

[0025] The swing arm rod 400 is symmetrically arranged on both sides of the frame 100, the upper end of the swing arm rod 400 is rotatably connected to the frame 100, and the lower end of the swing arm rod 400 is rotatably connected to the front end of the pedal rod 220; the rear end of the pedal rod 220 is rotatably connected to the free end of the crank 500 through a linkage mechanism; the fixed end of the crank 500 is fixedly connected to the rotating shaft of the rotating mechanism, so that the crank 500 drives the rotating shaft of the rotating mechanism to rotate;

[0026] The trajectory adjustment mechanism 600 includes a fixed block 610, a locking piece 620, and an adjusting rod 630 arranged on the swing arm rod 400. The fixed block 610 is provided with an adjustment groove in the length direction of the swing arm rod 400. At least two groups of adjustment holes are provided on the groove wall of the adjustment groove. A positioning hole is provided at one end of the adjusting rod 630. The locking piece 620 passes through the positioning hole and the adjustment hole to connect one end of the adjusting rod 630 with the fixed block 610, and the other end of the adjusting rod 630 is connected to the linkage mechanism.

[0027] When in use, the user applies force to the pedal 220 to change the position of the pedal rod 210, and at the same time drives the free end of the crank 500 to move, thereby driving the fixed end of the crank 500 to rotate along the axis of the rotating shaft of the rotating mechanism, thereby driving the rotating mechanism to rotate to form resistance, thereby achieving the purpose of movement, and the crank 500 is used to link the pedal rod 210 to produce reciprocating swing, which can perform pedaling movement, and the swing arm rod 400 can also produce reciprocating swing in cooperation with the pedal rod 200.

[0028] Furthermore, an adjustment rod 630 is provided between the swing arm 200 and the rotating linkage mechanism (i.e., the free end of the crank 500), and the distance and relative position between the swing arm 400 and the linkage mechanism (i.e., the free end of the crank 500) are controlled by the adjustment rod 630;

[0029] The adjusting rod 630 is detachably fixed to the fixing block 610 on the swing arm rod 400 via a locking piece 620. The user can quickly and conveniently install the end of the adjusting rod 630 connected to the fixing block 610 at different positions, thereby realizing rapid replacement of the adjusting rod 630, so that the distance and relative orientation between the swing arm rod 400 and the linkage mechanism can be adjusted quickly and conveniently, thereby allowing people to quickly and conveniently adjust the motion trajectory of the elliptical machine.

[0030] In this embodiment, a locking nut 611 is fixed outside the adjustment hole, and the locking member 620 includes an operating knob 621 and a screw rod 622. The screw rod 622 is provided with an external thread that matches the internal thread of the locking nut 611, thereby fixing it.

[0031] In this embodiment, the linkage mechanism includes a fixed shaft (not shown) and a roller 700; the fixed shaft is fixedly connected to the free end of the crank 500, and the roller 700 is rotatably sleeved outside the fixed shaft and can rotate around its own axis; the adjustment rod 630 is fixedly connected to the outer wall of the fixed shaft, and the pedal rod 210 is embedded in the annular groove of the roller 700. With the above structural design, the roller 700 can rotate around its axis, and the free end of the crank 500 and one end of the adjustment rod 630 can rotate around the axis of the rotating mechanism. Such a design makes the stride of the elliptical machine large.

[0032] In this embodiment, the fixing block 610 includes a support plate 612 and an enclosure plate 613, which enclose the adjustment groove. The support plate 612 has a support foot 6121 extending outward, and the support foot 6121 reserves an assembly space between the fixing block 610 and the swing arm rod 4001, which facilitates the extension of the screw 622 or the assembly of the fixing lock nut 611, thereby enhancing the fixing effect.

[0033] In this embodiment, the end of the adjusting rod 630 embedded in the adjusting groove is provided with an arc chamfer to avoid getting stuck during the adjustment process and causing the positioning hole and the adjusting hole to be unable to align.

[0034] In this embodiment, a barrier is arranged around the outer side of the pedal, and an anti-slip pattern is arranged on the top surface of the pedal.

[0035] In this embodiment, a plurality of anti-slip protrusions are arranged around the periphery of the operating knob 621 to enhance the anti-slip effect.

[0036] In this embodiment, the fixing block 610 is fixedly connected to the swing arm 400 or detachably connected.

[0037] In this embodiment, a display screen and an electronic device support seat are provided on the top of the rack 100 to facilitate displaying data and placing electronic devices; a cup holder 110 is fixedly connected to the middle of the rack 100 for placing cups.

[0038] In this embodiment, a handle is connected to the upper end of the frame 100 and / or the swing arm 400, so that people can hold the handle and follow the swing arm 400 to swing.

[0039] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
