[0005] A sleeve is provided at one end of the lifting assembly close to the track lifting assembly, and a fastener passes through the sleeve to connect the lifting assembly with the track lifting assembly.
[0006] The connecting shaft 2 is sleeved with the guide component 1, and the bottom frame is provided with the guide component 2 which matches with the guide component 1 structure.
[0007] The output shaft of the driving mechanism is connected to the transmission member via a threaded transmission structure.

[0015] The utility model is further described below with reference to the accompanying drawings.
[0016] like Figures 1 to 3 As shown, a driving mechanism 201 is provided on the base frame 101, and an output shaft 202 of the driving mechanism 201 is connected to one end of a transmission member 301, and the other end of the transmission member 301 is connected to a connecting shaft 1 401, and one end of a connecting plate 402 is respectively sleeved on the left and right sides of the connecting shaft 1 401, and the other end of the connecting plate 402 is sleeved on a connecting shaft 2 403, and a lifting assembly 501 is respectively provided on the left and right sides of the connecting shaft 2 403, and the lifting assemblies 501 on the left and right sides are respectively connected to the track lifting assembly 601.
[0017] A sleeve 502 is provided at one end of the lifting component 501 close to the track lifting component 601 , and a fastener 503 passes through the sleeve 502 to connect the lifting component 501 with the track lifting component 601 .
[0018] The connecting shaft 403 is sleeved with a guide assembly 701, and the bottom frame 101 is provided with a guide assembly 702 that matches the structure of the guide assembly 701. When used specifically, the guide assembly 701 is a roller, and the guide assembly 702 is a roller plate, and the roller moves along the roller plate to play a guiding role.
[0019] The output shaft 202 of the driving mechanism 201 is connected to the transmission member 301 via a threaded transmission structure to push the transmission member 301 .
[0020] A track 602 is disposed at the upper end of the track lifting assembly 601. The track 602 is matched with an elliptical car pulley 603.
[0021] One end of the driving mechanism 201 is fixed to the base frame 101 via a fixing plate 801 .
[0022] When the utility model is used, Figure 4As shown, the driving mechanism 201 is in motion, and the output shaft 202 of the driving mechanism 201 pushes the transmission member 301 through the threaded transmission structure, thereby pushing the lifting component 501 and the guide component 1 701 to roll in the guide component 2 702, and the lifting component 501 is continuously raised to lift the end of the track lifting component 601, so that the track lifting component 601 is raised to a corresponding slope, changing the starting position height of the elliptical vehicle pedal 901, thereby changing the motion trajectory and achieving a better motion effect.
[0023] like Figure 3 As shown, in the present invention, the number of connecting plates 402 and lifting components 501 is two. Through the cooperation of the two lifting components 501 and the track lifting component 601, the track lifting component 601 is lifted from two positions, which increases the width and reduces the shaking, ensuring more stability during lifting and use, thereby improving safety performance.
[0024] When used specifically, the driving mechanism 201 is a lifting motor, and the lifting component 501 is a lifting tube.
