[0035] The present application provides an elliptical exercise machine.

[0036] In the embodiments of the present application, please refer to Figures 1 to 5 The elliptical exercise machine 100 includes a support frame 10, a movement module, and a handle module 30. The support frame 10 includes a vertically extending vertical rod 11;

[0037] The movement module includes two movement assemblies arranged on both sides of the support frame 10 in a first direction; the movement assembly 20 includes a crank rocker structure and a stepping piece 212; the crank rocker structure includes a swing piece 2111, a connecting rod 2112, and a crank 2115; the swing piece 2111 is rotationally connected to the vertical rod 11; the two ends of the connecting rod 2112 are respectively rotationally connected to the swing piece 2111 and the crank 2115, and the crank 2115 is rotationally connected to the support frame 10; the stepping piece 212 is slidably connected to the connecting rod 2112 and is in transmission connection with the swing piece 2111 or the crank 2115; and

[0038] The handle module 30 comprises a connecting piece 31 and a handle rod 32, the connecting piece 31 comprises a first sleeve 311 extending in a first direction and a second sleeve 312 extending in a longitudinal direction, the first sleeve 311 is connected to the second sleeve 312; the first sleeve 311 is rotationally connected to the vertical rod 11 about its axis; the handle rod 32 comprises a movable section 321 hingedly connected to the swing piece 2111, and the movable section 321 is slidably inserted into the second sleeve 312;

[0039] The first direction is transverse, and the first direction and the longitudinal direction intersect.

[0040] In combination with the actual use scene of the elliptical exercise machine, the first direction can be understood as the left-right direction, and the longitudinal direction can be understood as the up-down direction. For the convenience of description, hereinafter, the first direction refers to the left-right direction, the longitudinal direction refers to the up-down direction, and the second direction refers to the front-rear direction.

[0041] In the embodiment, the support frame 10 is used to connect and fix other components, such as the movement module and the handle module 30, so as to ensure the stability and structural strength of the entire elliptical exercise machine 100. The vertical rod 11 provides longitudinal support. The support frame 10 is usually a profile structure, which can be made of steel (such as carbon steel or stainless steel) or aluminum alloy material. The shape and material of the support frame 10 or the vertical rod 11 are not limited herein.

[0042] The movement assembly is the core part of the elliptical exercise machine 100, which mainly functions to form an elliptical movement track through the cooperation between the crank rocker structure and the stepping piece 212. Specifically, when the user steps on the stepping piece 212 to rotate the crank 2115, the crank 2115 transmits the circular motion to the swing piece 2111 through the connecting rod 2112. Since the two ends of the connecting rod 2112 are rotationally connected to the crank 2115 and the swing piece 2111 respectively, the circular motion of the crank 2115 makes one end of the connecting rod 2112 move in a circle with the crank 2115, and the other end of the connecting rod 2112 pushes the swing piece 2111 to swing around the rotationally connected point of the swing piece 2111 and the vertical rod 11. At the same time, the swing of the swing piece 2111 will make the stepping piece 212 slide forward and backward along the connecting rod 2112 through the transmission connection between the swing piece 2111 and the stepping piece 212. At this time, since the crank 2115 is continuously rotating, the position and angle of the connecting rod 2112 are also constantly changing, which cooperates with the swing of the swing piece 2111 to make the movement track of the stepping piece 212 form an ellipse. In other words, when the crank 2115 rotates to a certain position, the connecting rod 2112 pushes the swing piece 2111 to swing in one direction, and at the same time, the stepping piece 212 slides forward; when the crank 2115 continues to rotate, the position of the connecting rod 2112 changes, the swing piece 2111 swings in the opposite direction, and the stepping piece 212 slides backward, which is repeated to realize the elliptical movement track.

[0043] The swing piece 2111 and the crank 2115 can be a rod-shaped structure or a disc-shaped structure, as long as they can be rotationally connected to the base, respectively. In order to reduce the weight, simplify the structure, and reduce the occupied space of the elliptical exercise machine 100, the swing piece 2111 and the crank 2115 adopt a rod-shaped structure. For the convenience of understanding, the swing piece 2111 and the crank 2115 are exemplarily described as rod-shaped structures in the following. The stepping piece 212 is used to provide stable support for the user's feet, and when the user steps on the stepping piece 212, the stepping piece 212 can realize power transmission to convert the action into the power of the crank rocker structure movement.

[0044] The handle module 30 is used to adjust and maintain the balance of the user's body by holding the handle, and to enhance the power of the movement. The first sleeve 311 provides a transverse rotation function, so that the handle rod 32 can be transversely rotated relative to the vertical rod 11. In this way, the swinging action of the arm in the front-back direction can be assisted. The second sleeve 312 provides a longitudinal adjustment function and guides and limits the movement of the handle rod 32. The handle rod 32 is generally cylindrical, which is convenient for the user to hold, and the surface thereof can also be treated to prevent slipping. The handle rod 32 can be made of aluminum alloy, plastic-coated metal rod, etc. The specific form and material of the handle rod 32 are not limited herein.

[0045] The movable section 321 can coordinate the movement of the handle rod 32 and the movement assembly, and reasonably guide the movement direction and amplitude of the handle rod 32 according to the swing of the swing piece 2111 and the position of the movable section 321 in the second sleeve 312, so that the swing amplitude of the handle rod 32 conforms to human movement.

[0046] The movable section 321 in the handle rod 32 is slidably inserted into the second sleeve 312, so that the swing amplitude of the handle rod 32 is inconsistent with that of the swing piece 2111. Specifically, when the swing piece has a large swing amplitude, the height and angle of the handle rod 32 are changed and adjusted by sliding up and down, so that the handle rod 32 has a smaller swing amplitude. For example, when the swing piece 2111 moves forward from the neutral position to the maximum step, the movable section 321 moves forward and downward appropriately to avoid the arm holding the handle rod 32 from suddenly having a large swing amplitude; when the swing piece 2111 moves backward from the maximum step position to the neutral position, the movable section 321 moves backward and downward appropriately to avoid the arm holding the handle rod 32 from suddenly having a large swing amplitude. In this way, the swing amplitude of the handle rod 32 is appropriately reduced, the discomfort or risk of falling caused by excessive swing of the arm during movement is avoided, and more stable support is provided for the user.

[0047] In some embodiments, the elliptical exercise machine 100 comprises a support frame 10, a movement module, and a handle module 30. The support frame 10 comprises a vertically extending upright 11. The movement module comprises two movement assemblies arranged on two sides of the support frame 10 in a first direction. Each movement assembly 20 comprises a crank rocker structure and a stepping member 212. The crank rocker structure comprises a swing piece 2111, a connecting rod 2112, and a crank 2115. The swing piece 2111 is rotationally connected to the upright 11. One end of the connecting rod 2112 is rotationally connected to the swing piece 2111, and the other end is slidably or rollably connected to the crank 2115. The crank 2115 is rotationally connected to the support frame 10. The stepping member 212 is fixedly connected to the connecting rod 2112 and drivingly connected to the swing piece 2111 or the crank 2115. The handle module 30 comprises a connecting piece 31 and a handle rod 32. The connecting piece 31 comprises a first sleeve 311 extending in the first direction and a second sleeve 312 extending in the vertical direction. The first sleeve 311 is connected to the second sleeve 312. The first sleeve 311 is rotationally connected to the upright 11 about an axis thereof. The handle rod 32 comprises a movable section 321 hingedly connected to the swing piece 2111. The movable section 321 is slidably inserted into the second sleeve 312. The first direction is transverse, and the first direction intersects the vertical direction.

[0048] Notably, when the stepping member 212 is fixedly connected to the connecting rod 2112, the stepping member 212 moves integrally with the connecting rod 2112. The movement trajectory of the stepping member 212 is determined by the movement of the connecting rod 2112. The position and posture of the stepping member 212 in space are fixed, and the movement form is relatively single and fixed. Since the stepping member 212 and the connecting rod 2112 are fixedly connected, they do not slide relative to each other during movement. This reduces the instability factors such as shaking and jamming that may occur due to sliding, making the elliptical exercise machine 100 more stable during operation. Users can feel more stable support during use, reducing safety hazards during exercise. The combination of the fixed connection of the stepping member 212 to the connecting rod 2112 and the handle module 30 in this embodiment can reduce the movement risk caused by the movable section 321 being slidably inserted into the second sleeve 312.

[0049] Further, please refer to Figures 4 to 6The handle rod 32 further comprises a holding section 322 fixedly connected with the upper end of the second sleeve 312, and the holding section 322 is detachably arranged with the movable section 321; when the swing piece 2111 swings, the movable section 321 can slide up and down along the inner wall surface of the second sleeve 312. In this way, the elliptical exercise machine 100 can still realize a smaller swing range of the handle rod 32 under a larger step range during operation of the elliptical exercise machine 100 through the up-and-down sliding between the movable section 321 and the second sleeve 312. Meanwhile, since the holding section 322 is detachably arranged with the movable section 321, the holding section 322 does not slide up and down with the movable section 321, thus providing a more stable and soft holding feeling for the user, especially under a high-intensity exercise or a larger step range, which can effectively reduce the vibration of the hands and improve the comfort of use.

[0050] In some embodiments, referring to Figures 1 to 3 , the holding section 322 is fixedly connected with or integrally formed with the movable section 321, and the holding section 322 and the movable section 321 simultaneously slide relative to the second sleeve 312 when the swing piece 2111 swings. In this way, the design step of accurately designing the length of the second sleeve 312 is omitted, and the installation is simplified. Meanwhile, since there is no gap or activity space at the connection position, the direction and size of the force can be more accurately controlled during transmission.

[0051] Further, referring to Figure 4 , the end of the swing piece 2111 has a highest point and a lowest point when swinging; and the length of the second sleeve 312 is greater than the height difference between the highest point and the lowest point. This means that when the swing piece 2111 swings to the highest point or the lowest point, the second sleeve 312 has enough space to accommodate the up-and-down sliding of the movable section 321, and prevents the movable section 321 from being detached from the second sleeve 312 due to an excessively large up-and-down sliding range. In other words, the movable section 321 has enough space to slide within the second sleeve 312, so that the movable section 321 and the second sleeve 312 will not collide. In this way, the connection relationship that the movable section 321 can slide up and down along the inner wall surface of the second sleeve 312 can be kept stable, and the violent shaking of the handle rod 32 caused by the large swing of the swing piece 2111 directly transmitted to the holding section 322 can be avoided, so that the user can hold the handle rod 32 more stably during exercise, reduces the risk of body imbalance caused by excessive shaking of the handle rod 32, and improves the stability during exercise.

[0052] In an embodiment, referring to Figures 1 to 4The swing 2111 is rotatably connected to the first connecting point 41, the movable segment 321 is rotatably connected to the swing 2111 at the second connecting point 42, and the connecting rod 2112 is rotatably connected to the swing 2111 at the third connecting point 43. The motion assembly further comprises an adjusting rod 213. One end of the adjusting rod 213 is fixedly connected to the stepping member 212, and the other end is rotatably connected to the lower end of the swing 2111 to form the fourth connecting point 44. The second connecting point 42 and the third connecting point 43 are located between the first connecting point 41 and the fourth connecting point 44.

[0053] In the present embodiment, the adjusting rod 213 can control the forward and backward sliding range of the stepping member 212, thereby adjusting the stride size of the user when using the elliptical exercise machine 100. For example, when the adjusting rod 213 is shortened or the connecting point between the adjusting rod 213 and the swing 2111 is moved upward, the forward and backward sliding range of the stepping member 212 can be reduced, and the stride of the user is correspondingly reduced. Conversely, when the adjusting rod 213 is lengthened or the connecting point between the adjusting rod 213 and the swing 2111 is moved downward, the stride is increased. In the present embodiment, the adjusting rod 213 is rotatably connected to the lower end of the swing 2111, and at this time, the forward and backward sliding range of the stepping member 212 is the largest.

[0054] The first connecting point 41 determines the rotation center of the swing 2111, the fourth connecting point 44 affects the position of the lower end of the swing 2111 through the adjusting rod 213, and the second connecting point 42 and the third connecting point 43 are located in the middle position and cooperate with each other to limit the swing range and movement direction of the swing 2111, thereby limiting the swing amplitude of the handle rod. At the same time, this layout helps to realize more uniform force transmission between various components. When the user steps on the stepping member 212, the force is transmitted from the adjusting rod 213 to the swing 2111 through the fourth connecting point 44, and the positions of the second connecting point 42 and the third connecting point 43 make the force more evenly distributed to the connecting rod 2112 and the movable segment 321, avoiding excessive concentration of force on a certain component. If the second and third connecting points 43 are not between the first and fourth connecting points 44, it may cause a certain component to bear excessive force, thereby affecting the service life of the component and the performance of the entire elliptical exercise machine 100.

[0055] Since the second connection point 42 and the third connection point 43 are located between the first connection point 41 and the fourth connection point 44, they form different lengths of force arms. Specifically, the force exerted on the swing 2111 by the connecting rod 2112 through the third connection point 43, and the force exerted on the swing 2111 by the adjusting rod 213 through the fourth connection point 44, together determine the final swing amplitude of the swing 2111. The handle rod 32 is connected to the swing 2111 only through the movable section 321 at the second connection point 42, and the length of the movable section 321 and its connection position relative to the swing 2111 form a unique force arm. When the swing 2111 swings, the force and motion transmission of the handle rod 32 change due to the different force arms. This is like the principle of leverage, where different force arms result in different motion amplitudes. If the swing of the swing 2111 is considered as a dynamic input, the dynamic transmission of the handle rod 32 will differ from the swing of the swing 2111 itself due to the different positions of the connection points and force arms.

[0056] Further, please refer to Figures 1 to 4 , the second connection point 42 and the third connection point 43 coincide or are spaced apart on the swing 2111.

[0057] In some embodiments, please refer to Figures 2 to 4 , the second connection point 42 and the third connection point 43 are coincidentally arranged. In this way, when the user steps on the stepping member 212 to rotate the crank 2115, the force transmitted through the connecting rod 2112 can more directly affect the motion of the movable section 321 and the handle rod 32, reducing the loss and transmission deviation of the force of the intermediate links. At the same time, this coincidental arrangement can improve the synchronization of the motion between the components, making the motion of the arms and legs more coordinated

[0058] In other embodiments, please refer to Figure 1 , the second connection point 42 and the third connection point 43 are spaced apart on the swing 2111. On the one hand, the spaced-apart connection points can optimize the force arms and moments of different components by adjusting their relative positions. This can achieve precise control of the motion assembly; it can also adjust the difficulty of the motion to meet the needs of different users. On the other hand, the spaced-apart arrangement of the two connection points can improve the stability of the motion assembly to some extent. When the swing 2111 swings, the two connection points can exert force on the swing 2111 at different positions, acting as mutual checks, avoiding the phenomenon of excessive swing or instability of the swing 2111 due to force on a single connection point. This helps to maintain the stability of the entire elliptical exercise machine 100 during the motion process, especially at high speeds or high intensity, preventing imbalance or damage caused by excessive motion of the components.

[0059] Further, please refer to Figures 2 to 4The second connecting point 42 is located between the first connecting point 41 and the third connecting point 43, and the second connecting point 42 is located below the first connecting point 41. Compared with the case that the second connecting point 42 is located between the third connecting point 43 and the fourth connecting point 44 or the case that the second connecting point 42 is located above the first connecting point 41, the second connecting point 42 in the embodiment is closer to the first connecting point 41. In this way, the distance between the first connecting point 41 and the second connecting point 42 is smaller, so that the swing range of the handle rod 32 is smaller. At the same time, the force transmission path is relatively short and direct, and the force transmission from the first connecting point 41 to the movable section 321 through the second connecting point 42 is more efficient. This helps to reduce the loss and deviation of the force in the transmission process, so that the movement of the movable section 321 (connected with the handle rod 32) is more stable and predictable.

[0060] In an embodiment, referring to Figures 1 to 4 The distance between the first connecting point 41 and the second connecting point 42 is less than or equal to 0.5 times the distance between the second connecting point 42 and the fifth connecting point. The ratio can be 0.47, 0.45, 0.4, 0.43, 0.41, 0.3, 0.33, 0.26, 0.2, 0.15, or 0.1. In this way, the second connecting point 42 is closer to the fifth connecting point, and the rotation of the swing piece 2111 at the first connecting point 41 is more strictly limited, so that the movement range of the movable section 321 connected thereto is also reduced, and the swing range of the handle rod 32 is also reduced accordingly. This design can effectively avoid the large swing of the handle rod 32 caused by the excessive swing of the swing piece 2111, so that the swing range of the handle rod 32 is within a reasonable and controllable range, and the stability and safety of the user during movement are improved.

[0061] In an embodiment, referring to Figure 1 The stand rod 11 includes an upper rod member 111 and a lower rod member 112 arranged in the longitudinal direction, and the upper rod member 111 and the lower rod member 112 are arranged in the second direction. The first sleeve 311 is rotationally connected to the upper rod member 111 in the first direction. The swing piece 2111 is rotationally connected to the lower rod member 112.

[0062] When the handle rod 32 swings, corresponding inertial force and reaction force are generated. The staggered arrangement and rotational connection in the embodiment can decompose and offset the inertial force and the reaction force.

[0063] Specifically, when the inertial force and the reaction force are transmitted from the handle bar 32, they are no longer simply transmitted along a straight line to the bottom of the vertical rod 11. In the present embodiment, when the force is transmitted from the handle bar 32 to the upper rod member 111, due to the misalignment of the upper rod member 111 and the lower rod member 112, part of the force is transmitted along the longitudinal direction of the upper rod member 111, while another part generates a horizontal or oblique component force due to the misalignment of the lower rod member 112, which decomposes the originally single-directional force into multiple directional component forces. This achieves the dispersion of the force. Meanwhile, the rotation of the swing member 2111 can generate a tangential force or a centripetal force along the connecting point of the swing member 2111 and the lower rod member 112, which changes the direction and size of the original force, resulting in the change of the size and direction of the force transmitted back to the handle bar 32, so that the handle bar 32 cannot continuously obtain sufficient energy to maintain its unlimited swing, and eventually cannot swing unlimitedly, but moves within a certain range of amplitude, achieving the effect of limiting the swing amplitude of the handle bar 32.

[0064] In an embodiment, please refer to Figures 1 to 4 , the second connecting point 42 and the third connecting point 43 are coincidentally arranged; the connecting rod 2112 comprises a first segment 2113 and a second segment 2114 connected to each other, the first segment 2113 extends along the second direction, and the second segment 2114 is arranged upwardly inclined relative to the first segment 2113; the first segment 2113 is slidingly connected with the stepping member 212; the end surface of the second segment 2114 away from the first segment 2113 has a mounting groove 2116; and the movable segment 321 is rotatably mounted in the mounting groove 2116.

[0065] In the present embodiment, during the movement of the elliptical exercise machine 100, the extension direction of the first segment 2113 matches the forward and backward sliding direction of the stepping member 212, providing certain support and guidance for the movement of the stepping member 212, and ensuring that the stepping member 212 can stably slide along the predetermined second direction. The second segment 2114 is arranged upwardly inclined relative to the first segment 2113. This inclination can change the transmission path and direction of the force, so that the connecting rod 2112 can not only transmit the horizontal force during movement, but also convert part of the force of the user stepping on the stepping member 212 into upward force, so that the movement of the elliptical exercise machine 100 is closer to the natural elliptical movement track.

[0066] During the operation of the elliptical exercise machine 100, the forward and backward sliding of the stepping member 212 drives the movement of the first segment 2113 of the connecting rod 2112, and the inclined structure of the second segment 2114 of the connecting rod 2112 transmits this movement to the movable segment 321, and the rotation of the movable segment 321 transmits the movement to the handle bar 32. Through this cooperation, the leg movement (through the stepping member 212) of the user and the arm movement (through the handle bar 32) can be better coordinated to achieve more smooth and coordinated whole-body movement.

[0067] In an embodiment, referring to Figures 1 to 4 The first sleeve 311 and the second sleeve 312 are arranged along a second direction; the longitudinal direction, the first direction and the second direction are perpendicular to each other. The second direction is the front-rear direction. In this way, the first sleeve 311 and the second sleeve 312 occupy corresponding spaces in the front-rear dimension, facilitating the connection and cooperation with other components (such as the handle rod 32, the connecting rod 2112, etc.), avoiding the conflict and interference between components in space, thereby realizing a more compact and efficient structure design.

[0068] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not drive the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
