Description

Treadmill

Technical field

The invention relates to the technical field of fitness equipment, in particular to a treadmill.

Background technique

A treadmill is also called a walking machine. It generally includes a running board, a front roller driven by a driving and transmission mechanism and located at the front end of the running board, a rear roller located at the rear end of the running board, tensioned on the front roller and the rear roller and covering it. The running belt outside the running board.

Although some running boards are divided into front running boards and rear running boards, and hinges are arranged between the front running boards and the rear running boards, the existing treadmills still have a common shortcoming: the manufacturing and manufacturing of the front and rear running boards. There are many assembled components, the installation structure of the front and rear running boards is relatively complicated, the manufacturing and assembly components between the running boards and the front end frame are numerous, the structure is trivial, the installation of the drive mechanism and the control electrical appliances is time-consuming and laborious, and the front end frame and the front running board are different There is always a contradiction in the connection between the two: the frame is welded first, and then the drive mechanism and the control appliance are installed. The installation requires a large space, resulting in a large frame, more consumables, increased volume and cost, and the installation of the drive mechanism and the control appliance is subject to different directions. Space constraints are still very inconvenient; first install the drive mechanism and control electrical appliances and then weld, the high temperature of welding will inevitably cause damage to electrical parts such as the control circuit board, resulting in low product yield of treadmills. The above prior art also has a common shortcoming: the stability and firmness of the simple running board structure are insufficient.

Summary of the invention

The technical problem to be solved by the present invention is to provide a treadmill that can be separately manufactured and then modularly assembled.

The technical solution of the present invention is to provide a treadmill, comprising a front treadmill with a front roller at the front end and a rear treadmill with a rear roller at the rear end, tensioned on the front roller and the rear roller and covering the front roller The front running board of the platform and the running belt outside the rear running board of the rear running platform also include an electrical module that assembles the drive transmission mechanism and the control electrical appliances on the front frame.
