Description

Technical Field

[0001] This application relates to the field of elliptical machine technology, and in particular to an elliptical machine capable of adjusting positive and negative inclines. Background Technology

[0002] As people place greater emphasis on exercise, they are increasingly purchasing elliptical trainers for daily workouts. These trainers are popular because they can prevent, reduce, and alleviate pain in the neck, shoulder, and upper back, while also avoiding the impact of running, thus better protecting the joints and providing a higher safety factor.

[0003] Some users require training at different inclines, so some elliptical trainers are equipped with an incline adjustment device. However, existing incline adjustment devices, such as the folding elliptical trainer stabilization system proposed in announcement number CN105407981B, directly raise the height of one end of the elliptical trainer through an actuator. However, this adjustment method can only adjust the positive or negative angle. It is quite troublesome to install actuators at both ends of the elliptical trainer. Therefore, how to solve the above problems is the purpose of this application.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0007] In some embodiments, the slope seat includes a support rod, a telescopic rod, and a telescopic device. The support rod is fixedly installed and hinged to the rotating block. One end of the telescopic rod is hinged to the rotating block, and the other end can extend and retract within the telescopic device. The telescopic device drives the rotating block to rotate around the hinge point of the support rod.

[0008] In some embodiments, the rolling element is a cylinder with two flanges, and the top of the rotating block is provided with a cylindrical portion that mates with the rolling element.

[0009] In some embodiments, a pedal shaft is mounted on one side of the second connecting rod, the pedal is rotatably mounted on the pedal shaft, and a torsion spring is mounted on the pedal shaft.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0019] In the embodiments of this application, please refer to Figure 1-3 As shown, this application provides an elliptical machine capable of adjusting positive and negative inclines, mainly comprising: a base frame 1; an incline assembly 2, fixedly mounted on the base frame 1, the incline assembly 2 including an incline seat 21 and a rotating block 22, the rotating block 22 being rotatable on the incline seat 21 and temporarily fixed, the rotating block 22 being able to adjust the incline of the elliptical machine by rotation; a return mechanism 3, having a return point that can move on a circular trajectory, disposed above the base frame 1; a main frame 4, fixedly mounted above the base frame 1; and a first connecting rod 5, rotatably mounted on the base frame 1. The first connecting rod 5 is located on both sides of the main frame 4. One end of the first connecting rod 5, which is connected to the main frame 4, extends to form a swing arm 51. The second connecting rod 6 is hinged to the first connecting rod 5 at one end, and a pedal 61 is provided on one side of the other end. The third connecting rod 7 is hinged to the winding point of the winding mechanism 3 at one end, and a rolling element 71 is provided on the other end to abut against the rotating block 22. The rolling element 71 can roll along the length direction of the rotating block 22. Both the second connecting rod 6 and the third connecting rod 7 are provided with connecting parts, and the two connecting parts can rotate relative to each other.

[0020] Specifically, when the user exercises on the elliptical machine, the first connecting rod 5, the second connecting rod 6, and the third connecting rod 7 will all move synchronously under the action of the rewinding mechanism 3. Since the rolling element 71 can only roll on the rotating block 22, the movement trajectory of the slope of the pedal 61 will change when the rotating block 22 is at different angles. The rotating plate can rotate a large range, so that the elliptical machine can adjust the positive and negative slope.

[0021] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0022] Reference Figure 2 As shown, in order to drive the rotating block 22 to rotate, the slope seat 21 includes a support rod 211, a telescopic rod 212, and a telescopic device 213. The support rod 211 is fixedly set and hinged to the rotating block 22. One end of the telescopic rod 212 is hinged to the rotating block 22, and the other end can extend and retract within the telescopic device 213. The telescopic device 213 drives the rotating block 22 to rotate around the hinge point of the support rod 211.

[0023] Specifically, the rolling element 71 is a cylinder with two flanges 711. The top of the rotating block 22 is provided with a cylindrical part 221 that cooperates with the rolling element 71. The flanges 711 can prevent the rolling key from being misaligned and falling off when it rolls on the cylindrical part 221, thus preventing personal safety hazards.

[0024] Reference Figure 3 As shown, a pedal shaft 62 is installed on one side of the second connecting rod 6. The pedal 61 is rotatably mounted on the pedal shaft 62, and a torsion spring 63 is provided on the pedal shaft 62 to prevent the pedal 61 from being misaligned. An abutment plate 64 is rotatably mounted on the other end of the second connecting rod 6, which is connected to the first connecting rod 5. The abutment plate 64 is positioned below the pedal 61 and includes three protruding edges 641 of different sizes. The torsion spring 63 enables the pedal 61 to always drive towards the abutment plate 64. The abutment plate 64 serves as a rear support for the pedal 61 and is supported by two of the protruding edges 641. By rotating the abutment plate 64, the two different protruding edges 641 abut against the bottom of the pedal 61, allowing the abutment plate 64 to have different support heights to adapt to different slopes or user habits.

[0025] Preferably, the telescopic device 213 drives the telescopic rod 212 to move through any one of the following: motor screw drive, electric push rod, and hydraulic push rod. Specifically, in this embodiment, motor screw drive is used. A receiving tube is also provided below the telescopic device 213 to accommodate the retracted telescopic rod 212.
