Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of elliptical machines, in particular to a foldable elliptical machine. BACKGROUND

[0002] As a low-impact, full-body exercise equipment, elliptical machines are widely used in homes and gyms. However, traditional elliptical machines are usually large in size and occupy a lot of space, which is particularly problematic in urban environments where living space is limited. In addition, the transportation and installation of traditional elliptical machines are also relatively inconvenient, limiting their application in certain scenarios.

[0003] Therefore, foldable elliptical machines have appeared on the market, such as the foldable elliptical machine disclosed in Publication No. CN103170097B. The rear frame and the front frame are folded through an oil cylinder assembly and a rotating assembly, and the foot pedal pipe is installed and removed with the rear frame through a clamping assembly, reducing the floor space and the packaging size, improving the cabinet loading capacity, and facilitating movement. The oil cylinder can effectively lock in the current state in the folded state, preventing the rear frame from falling due to accidental touch. However, the use of an oil cylinder assembly is costly and requires electrical adjustment, which requires additional power supply at the bottom of the rear frame. Therefore, how to solve the above problems is the purpose of the present application.

[0004] The above content is only used to assist in understanding the technical solutions of the present application and does not represent the acknowledgement of the above content as the closest prior art to the present application. SUMMARY

In addition, the technical solutions in each embodiment can be combined with each other, but the combination of the technical solutions should be based on the fact that a person of ordinary skill in the art can realize the combination, and when the combination of the technical solutions appears contradictory or unachievable, it should be considered that the combination of the technical solutions does not exist and is not within the protection scope of the application.

[0023] In the embodiments of the application, please refer to Figures 1-5 It is provided that a foldable elliptical machine mainly includes: a chassis 1; a main frame 2 arranged above the chassis 1; a folding mechanism 3 including a folding point capable of rotating along a circular track, the folding point being provided with a connecting pipe 31 capable of rotating, and the folding mechanism 3 being hinged to one end of the chassis 1; a first connecting rod 4 hinged to two sides of the main frame 2; a second connecting rod 5 hinged to one end of the first connecting rod 4 and provided with a clamping pipe 51 and a clamping assembly 52 at the other end for cooperating with the connecting pipe 31, and the second connecting rod 5 being provided with a pedal 53 at the top; and the second connecting rod 5 and the folding mechanism 3 being capable of rotating into a normal state and a folding state.

[0024] In the normal state, the clamping pipe 51 is clamped on the connecting pipe 31 and locked by the clamping assembly 52, so that the second connecting rod 5 can rotate together with the folding point to form a movement track.

[0025] In the folded state, the clamping pipe 51 is no longer connected with the connecting pipe 31, so that the second connecting rod 5 becomes a free state and is folded with the first connecting rod 4, and the winding mechanism 3 is folded with the base frame 1, so that the winding mechanism 3 is located above the base frame 1, thereby reducing the floor space.

[0026] As an illustration, the structure principle that the clamping assembly 52 and the clamping pipe 51 can be temporarily locked on the connecting pipe 31 can refer to a foldable elliptical machine disclosed in CN103170097B, and has no direct relevance to the problem solved by the present application, so it is not necessary to make a detailed description.
