Description

Technical Field

[0001] This utility model belongs to the field of treadmill technology, and specifically relates to a treadmill tilt angle adjustment mechanism. Background Technology

[0002] Existing treadmill platforms typically feature incline adjustment feet to allow for easy adjustment of the platform's incline, thus allowing the treadmill to be set to different usage positions to meet the needs of different users. These incline adjustment feet generally include a rotatable foot mounted at one end of the frame, along with a locking pin. The rotatable foot is adjusted and then secured by the pin, raising or lowering one end of the platform. The drawback of this design is that adjustment requires manually lifting one end of the treadmill and rotating the rotatable foot, a process that usually requires two people and is therefore cumbersome. Utility Model Content

[0003] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a treadmill tilt angle adjustment mechanism to solve the problems mentioned in the background art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A treadmill tilt angle adjustment mechanism includes a running platform frame and two rotating arms rotatably connected to the front end of the running platform frame. The two rotating arms are arranged opposite to each other. Each rotating arm includes an arm body with a support portion formed on the arm body. The support portion forms a variable tilt angle with the running platform frame through a rotating connection structure. The rotating connection structure includes a rotating shaft connected between the two rotating arms. The rotating shaft is connected to a rotating shaft rotation drive. The rotating shaft is driven to rotate by the rotating shaft rotation drive, which in turn drives the support portion to rotate to adjust the angle between the support portion and the running platform frame, thereby raising or lowering the front end of the running platform frame.

[0006] In this application, a variable tilt angle is formed between the support part and the treadmill frame to raise or lower the front end of the treadmill frame, thereby adjusting the tilt angle of the treadmill frame.

[0007] Preferably, the arm body includes a connecting part, the bottom end of which is bent to form the supporting part, and a supporting wheel is provided on the supporting part.

[0008] Preferably, the support wheel is rotatably connected to the bottom end of the support portion.

[0009] Preferably, in the initial state, the tilt angle between the support and the running platform frame is 0 degrees, meaning they remain parallel. This is the stowed-in state.

[0010] Preferably, the rotary shaft rotation drive includes a telescopic rod hinged to the rotary shaft. The telescopic rod is connected to the telescopic drive, which drives the telescopic rod to extend and retract. The extension and retraction of the telescopic rod simultaneously propels the rotary shaft to rotate. The rotation of the rotary shaft then drives the rotary arm to rotate.

[0011] Preferably, the telescopic rod includes a telescopic rod body, with a nut integrally formed inside the telescopic rod body. A screw is connected to the nut by an internal thread. A first gear is fixedly connected to the bottom of the screw. A second gear is driven by the first gear. The telescopic drive includes a drive motor, and the second gear is fixed on the output shaft of the drive motor.

[0012] The drive motor is fixed to the running platform frame. The fixing structure is existing technology and will not be described in detail here.

[0013] Preferably, a connecting shaft is provided on the inner side wall of the running platform frame, and a rotating hole is provided on the connecting part. The arm body is rotatably connected to the connecting shaft by passing a nut through the rotating hole.

[0014] Preferably, a hinge seat is welded to the rotating shaft, and a crossbar is provided through the hinge seat. The crossbar passes through the top end of the telescopic rod body and hinges the telescopic rod body to the hinge seat.

[0015] In summary, the present invention has the following main advantages:

[0016] This application solves the problem of requiring multiple people to adjust the inclination of the running platform by setting up a rotating arm and a rotating shaft driven by the rotating arm. This electrically driven mechanism rotates the arm, thus raising and lowering the running platform frame. Operation is now much more convenient. Attached Figure Description

[0022] refer to Figures 1 to 5This embodiment of a treadmill tilt angle adjustment mechanism includes a running platform frame 1 and two rotating arms 2 rotatably connected to the front end of the running platform frame. The two rotating arms are arranged opposite to each other. Each rotating arm includes an arm body with a support portion 4 formed on the arm body. The support portion forms a variable tilt angle with the running platform frame through a rotating connection structure. The rotating connection structure includes a rotating shaft 5 connected between the two rotating arms. The rotating shaft is connected to a rotating shaft rotation drive component. The rotating shaft is driven to rotate by the rotating shaft rotation drive component, which in turn drives the support portion to rotate to adjust the angle between the support portion and the running platform frame, thereby raising or lowering the front end of the running platform frame.

[0023] In this application, a variable tilt angle is formed between the support part and the treadmill frame to raise or lower the front end of the treadmill frame, thereby adjusting the tilt angle of the treadmill frame.

[0024] Specifically, the arm body includes a connecting part 6, the bottom end of which is bent to form the support part. A support wheel 7 is mounted on the support part and is rotatably connected to the bottom end of the support part. The support wheel reduces the resistance generated during the rotation of the arm. In the initial state, the tilt angle between the support part and the running platform frame is 0 degrees, meaning they remain parallel. This is the stowed state.

[0025] The rotating shaft drive includes a telescopic rod 8 hinged to the rotating shaft. The telescopic rod is connected to the telescopic drive, which drives the telescopic rod to extend and retract. The telescopic rod's extension and retraction simultaneously propels the rotating shaft. The rotation of the rotating shaft drives the rotating arm to rotate. The telescopic rod includes a telescopic rod body 9, with a nut 10 integrally formed inside. A screw 11 is threaded onto the nut, and a first gear (not shown) is fixedly connected to the bottom of the screw. The first gear is driven by a second gear (not shown). The telescopic drive includes a drive motor, and the second gear is fixed to the output shaft of the drive motor. This is prior art and will not be described further.
