[0028] The utility model provides an elliptical fitness equipment.
[0029] In the embodiment of the utility model, please refer to Figure 1 and Figure 2 The elliptical fitness equipment 100 includes a frame 10, a movement module, and a handrail 30. The frame 10 includes a vertical rod 11 extending in the longitudinal direction. The movement module includes two movement assemblies 21 arranged on the left and right sides of the frame 10. The movement assembly 21 includes a crank rocker structure and a footrest 23. The crank rocker structure includes a swing member 221, a connecting rod 222, and a crank 223. The swing member 221 is rotationally connected to the vertical rod 11. The two ends of the connecting rod 222 are rotationally connected to the swing member 221 and the crank 223, respectively. The crank 223 is rotationally connected to the frame 10. The footrest 23 is connected to the connecting rod 222 and is in transmission connection with the swing member 221 or the crank 223. The handrail 30 is rotationally connected to the vertical rod 11, and the lower end of the handrail 30 is in rotational and upward / downward sliding connection with the swing member 221.
[0030] In this embodiment, the frame 10 is the basic frame of the elliptical fitness equipment 100, providing a support structure. The frame 10 can be made of a metal material, such as steel or aluminum alloy, to ensure sufficient strength and stability. The shape of the frame 10 can be L-shaped or other shapes, which is not limited here. The vertical rod 11 extends in the longitudinal direction to ensure the stability of the movement assembly 21 and the handrail 30 and reduce the possibility of shaking or instability of the equipment during movement.
[0031] The movement module / movement assembly 21 is driven by the crank rocker structure to slide the footrest 23 forward and backward, simulating the movement mode of walking or running.
[0032] Specifically, when the user steps on the footrest 23 to rotate the crank 223, the crank 223 transmits the circular motion to the swing 221 through the connecting rod 222. Since the two ends of the connecting rod 222 are respectively rotationally connected with the crank 223 and the swing 221, the circular motion of the crank 223 makes one end of the connecting rod 222 move with the crank 223, and the other end of the connecting rod 222 pushes the swing 221 to swing around the rotationally connected point with the vertical rod 11. At the same time, the swing of the swing 221 makes the footrest 23 move back and forth through the connection of the connecting rod 222 with the footrest 23. At this time, since the crank 223 is continuously rotating, the position and angle of the connecting rod 222 are also changing, which cooperates with the swing of the swing 221 to make the movement trajectory of the footrest 23 form an ellipse. In other words, when the crank 223 rotates to a certain position, the connecting rod 222 pushes the swing 221 to swing in one direction, and at the same time, the footrest 23 moves forward; when the crank 223 continues to rotate, the position of the connecting rod 222 changes, the swing 221 swings in the opposite direction, and the footrest 23 moves backward, and so on, to realize the elliptical movement trajectory.
[0033] The connection mode of the connecting rod 222 and the footrest 23 includes that the footrest 23 is fixedly connected to the connecting rod 222 and that the footrest 23 is slidably connected to the connecting rod 222.
[0034] When the footrest 23 is fixedly connected to the connecting rod 222, one end of the connecting rod 222 is rotationally connected to the swing 221, and the other end is slidably or rollably connected with the crank 223. The footrest 23 moves as a whole with the connecting rod 222, and the movement trajectory of the footrest 23 is determined by the movement of the connecting rod 222, and the position and posture of the footrest 23 in space are fixed, the movement form is relatively single and fixed. Since the footrest 23 and the connecting rod 222 are fixed as a whole, there is no relative sliding between them during movement. This reduces the instability factors such as shaking and jamming that may occur due to sliding, so that the elliptical fitness equipment 100 runs more stably. Users can feel more stable support during use, reducing the safety hazards during movement.
[0035] When the footrest 23 is slidably connected to the connecting rod 222, the footrest 23 not only swings with the connecting rod 222, but also slides forward and backward relative to the connecting rod 222, and the movement trajectory is no longer determined by the connecting rod 222 alone, but also affected by the sliding of the footrest 23 on the connecting rod 222. This makes the movement trajectory of the elliptical fitness equipment 100 more variable, adding an additional movement dimension, and bringing users a novel movement experience. At the same time, the slidable feature of the footrest 23 can better simulate the forward and backward displacement of the feet during natural walking or running, making users feel more natural and comfortable when using the elliptical fitness equipment 100, reducing the risk of body fatigue and injury caused by unnatural movement trajectory.
[0036] The swing member 221 and the crank 223 can be a rod structure or a disc structure, as long as they can be rotationally connected to the frame 10. In order to reduce the weight, simplify the structure, and reduce the occupied space of the elliptical fitness machine 100, the swing member 221 and the crank 223 are in a rod structure. For the convenience of understanding, the swing member 221 and the crank 223 are exemplarily described as a rod structure in the following. One end of the swing member 221 is hingedly connected to the frame 10, so as to rotationally connect the swing member 221 to the frame 10.
[0037] The pedal member 23 is used to provide stable support for the user's feet, and when the user steps on the pedal member 23, the pedal member 23 can realize power transmission to convert the action into the power of the crank rocker structure movement. The pedal member 23 is reciprocally and slidably connected to the connecting rod 222, and specifically can include a pedal seat and a roller assembly connected to the pedal seat, so that the pedal seat is slidably connected to the connecting rod 222 through the roller assembly. The pedal seat can only include a pedal, or can include a pedal, a front baffle, a rear baffle, a side baffle, etc. The structure of the roller assembly can also be various, for example, the roller assembly can include a plurality of groups of rollers arranged on the front and rear sides of the pedal seat, and the plurality of groups of rollers are lapped on the connecting rod 222 to realize the sliding connection between the pedal member 23 and the connecting rod 222. In other embodiments, each group of rollers can include an upper roller and a lower roller, so that the pedal seat clamps the upper and lower sides of the connecting rod 222 through the upper and lower rollers on the side to realize the sliding connection between the pedal member 23 and the connecting rod 222. The specific structure of the pedal member 23 is not limited herein.
[0038] The handrail member 30 provides balance support during user movement, reducing the risk of falling due to excessive or unstable movement amplitude. The handrail member 30 can be made of plastic, rubber or metal composite material, providing a comfortable grip and being strong enough to withstand the constant force during movement. The handrail member 30 is rotationally connected to the vertical rod 11, so that the handrail member 30 rotates according to the movement mode and pace of the user, which can ensure that the handrail member 30 always rotates within a certain stable range, avoiding excessive swing or out-of-control situations.
[0039] The lower end of the handrail member 30 is rotationally and slidably connected to the swing member 221, so that the swing amplitude of the handrail member 30 is inconsistent with the swing amplitude of the swing member 221. In other words, when the swing member 221 has a large swing amplitude, the height of the connection point between the handrail member 30 and the swing member 221 changes due to the up-and-down sliding, thereby causing the handrail member 30 to have a smaller swing amplitude. In this way, the handrail rod of the traditional elliptical fitness machine 100 is prevented from having an excessive swing amplitude due to the large swing amplitude of the swing member 221, ensuring that the handrail rod can always provide the best support during movement, so that the user does not have to frequently adjust the posture or worry about falling.
[0040] Further, please refer toFigure 1 and Figure 2 One of the handrail member 30 and the swing member 221 is provided with a groove 31, and the other is provided with a protrusion 32; the groove 31 extends in a strip shape, and the extension direction of the groove 31 is arranged at an angle with the front-rear direction; the protrusion 32 slides along the extension direction of the groove 31; the left-right direction, the longitudinal direction, and the front-rear direction are perpendicular to each other in pairs.
[0041] In the embodiment, the groove 31 functions to guide and limit the sliding trajectory of the protrusion 32, thereby limiting the swing angle of the handrail member 30. The length of the groove 31 is set to control the up-down sliding range of the handrail within a certain range, avoiding the feeling of instability caused by too large or too small amplitude. Since the extension direction of the groove 31 is arranged at an angle with the front-rear direction, the protrusion 32 will be subject to a certain resistance during sliding, which helps to limit the swing angle of the handrail member 30 and prevent it from swinging excessively. The cooperation between the protrusion 32 and the groove 31 ensures the precise positioning and sliding between the components, preventing misalignment or excessive sliding.
[0042] Further, please refer to Figure 1 and Figure 2 The handrail member 30 is in the shape of a rod, and when the handrail member 30 is provided with the groove 31, the length direction of the groove 31 is arranged in parallel with the length direction of the handrail member 30.
[0043] In the embodiment, the handrail member 30 is in the shape of a rod, making the handrail rod more ergonomic and convenient for users to hold. At the same time, compared with large handrails or handrails of complex shapes, the rod-shaped handrail member 30 can effectively save the occupied space. Parallel means parallel or close to parallel. Since the length direction of the groove 31 is arranged in parallel with the length direction of the handrail member 30, a stable straight sliding path is formed on the groove 31. Compared with a curved sliding path, a straight sliding path is easier to control and predict, thus reducing the shaking or instability of the handrail rod caused by path changes, thereby helping to reduce the fatigue of the arms and wrists and providing a more comfortable and natural holding experience for the user.
[0044] In an embodiment, Figure 1 and Figure 2 The swing member 221 is rotationally connected to the vertical rod 11 at a first connection point 41; the swing member 221 is slidingly connected to the handrail member 30 at a second connection point 42; the second connection point 42 is arranged adjacent to the first connection point 41, and the second connection point 42 is located below the first connection point 41.
[0045] In the embodiment, the first connection point 41 is the rotation center of the swing member 221. The distance between the first connection point 41 and the second connection point 42 determines the maximum distance of the swing of the handrail rod. The second connection point 42 is arranged adjacent to the first connection point 41, which means the distance between the first connection point 41 and the second connection point 42 is relatively small, and thus the swing path of the handrail rod is shortened.
[0046] When the second connection point 42 is above the first connection point 41, the handrail rod may swing and vibrate greatly due to the gravity during the swing. Especially at high speed, the swing may be intensified, which leads to the decrease of the structural stability. In the embodiment, the second connection point 42 is below the first connection point 41, and the overall gravity center of the handrail rod is relatively low, which makes the handrail rod tend to keep stable during the swing due to the gravity.
[0047] Further, referring to Figure 1 or Figure 2 , the first connection point 41 and the second connection point 42 are the first section of the swing member 221; the swing member 221 is rod-shaped, and the ratio of the length of the first section to the length of the swing member 221 is greater than 0 and less than or equal to 0.5.
[0048] In the embodiment, the distance between the first connection point 41 and the second connection point 42 determines the maximum distance of the swing of the handrail rod. If the first section is relatively short (not more than half of the total length), the movement range of the swing member 221 can be effectively limited, so as to improve the stability of the system and avoid the problems of imbalance and excessive movement due to the too large swing range. At the same time, the shorter first section means that the force transmission path from the first connection point 41 to the second connection point 42 is shorter, and thus the loss and dispersion of the force are correspondingly reduced. This enables the user to more directly and effectively control the swing of the handrail rod, and thus realize more accurate range control. The ratio of the length of the first section to the length of the swing member 221 is greater than 0 and less than or equal to 0.5, which can be 0.5, 0.45, 0.42, 0.4, 0.36, 0.3, 0.27, 0.2, 0.23, 0.1, etc., so as to accurately control the swing range of the handrail member 30 and provide a better movement experience.
[0049] In an embodiment, referring to Figure 1 or Figure 2 , one end of the connecting rod 222 is rotationally connected to the crank 223, and the other end is rotationally connected to the swing member 221 at the third connection point 43, and the second connection point 42 is between the first connection point 41 and the third connection point 43.
[0050] In this embodiment, the second connection point 42 is located between the first connection point 41 and the third connection point 43, which limits the swing amplitude of the handrail rod. The first connection point 41 is the rotation center of the swing member 221, the movement of the third connection point 43 is transmitted to the swing member 221 through the connecting rod 222, and the second connection point 42 is located between them, like a "constraint point". When the swing member 221 rotates around the first connection point 41 under the drive of the connecting rod 222, the movement range of the handrail member 30 at the second connection point 42 is limited within a relatively small interval. Compared with the second connection point 42 located at other positions (such as the second connection point 42 close to the edge of the swing member 221), this position relationship can prevent the handrail member 30 from swinging with a large amplitude due to excessive degrees of freedom.
[0051] Further, please refer to Figure 1 or Figure 2 , the movement assembly 21 further comprises an adjusting rod 24; one end of the adjusting rod 24 is fixedly connected to the foot pedal 23, and the other end is rotatably connected to the swing member 221; the foot pedal is slidably connected to the connecting rod. In this embodiment, the user can drive the swing member 221 to swing by applying force to the adjusting rod 24 through the foot pedal 23, thereby increasing the flexibility of movement control. The length of the adjusting rod 24 directly affects the swing radius of the swing member 221. When the length of the adjusting rod 24 is longer, the swing radius increases, and the swing member 221 will swing to a larger angle under the action of the same torque, thereby increasing the swing amplitude. Conversely, when the length of the adjusting rod 24 is shorter, the swing radius decreases, and the swing amplitude will also decrease accordingly.
[0052] Further, please refer to Figure 1 or Figure 2 , the adjusting rod 24 and the swing member 221 are rotatably connected to the fourth connection point 44; the fourth connection point 44 and the first connection point 41 are located at two ends of the swing member 221 in the length direction; 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.
[0053] In this embodiment, the first connection point 41 and the fourth connection point 44 are located at the two ends of the swing member 221, which ensures that the swing member 221 can rotate or adjust evenly between the two end points. The first connection point 41 provides support and rotation function, and the fourth connection point 44 controls the angle or position of the swing member 221, so that the whole swing process is more stable and adjustable.
[0054] The layout of the second connection point 42 and the third connection point 43 between the first connection point 41 and the fourth connection point 44 makes the handrail rod not consistent with the swing amplitude of the lower end of the swing member 221 during the swing process. In other words, the swing amplitude of the handrail rod is smaller than the swing amplitude of the lower end of the swing member 221 during the swing process.
[0055] Meanwhile, the handrail rod can slide up and down on the second connection point 42 and the swing member 221. In this way, in the case that the swing member 221 has a large swing range, the handrail rod can be flexibly adjusted in position to avoid being directly impacted by an excessively large force, thereby reducing the swing range. In other words, in the case that the swing member 221 has a large swing range, the sliding movement ensures that the handrail rod does not rotate excessively at a fixed point, thereby reducing the influence of the moment on the handrail rod and avoiding excessive swing caused by an excessively large moment.
[0056] In an embodiment, referring to Figure 1 or Figure 2 , the swing member 221 is rotationally connected to the upright rod 11 at the first connection point 41, and the swing member 221 is slidingly connected to the handrail member 30 at the second connection point 42. The second connection point 42 is adjacent to the first connection point 41. The handrail member 30 is rotationally connected to the upright rod 11 at the fifth connection point 45. The ratio of the distance between the second connection point 42 and the fifth connection point 45 to the distance between the first connection point 41 and the second connection point 42 is less than or equal to 2.
[0057] The distance between the second connection point 42 and the fifth connection point 45 determines the maximum rotation radius of the handrail rod relative to the upright rod 11 (or the main frame of the elliptical machine). When this distance is reduced, the rotation radius of the handrail rod is reduced, thereby possibly reducing the swing range of the handrail rod. The distance between the first connection point 41 and the second connection point 42 determines the swing space of the handrail rod through the second connection point 42. When this distance is increased, the potential swing range of the handrail rod during the swing process is greater. In the present embodiment, the ratio of the distance between the second connection point 42 and the fifth connection point 45 to the distance between the first connection point 41 and the second connection point 42 is greater than 0 and less than or equal to 4. The ratio can be 4, 4.5, 4.6, 3, 2, 2.32, 1.5, 1, 1.32, 0.5, 0.3, respectively. In this way, the swing range of the handrail rod can be effectively controlled.
[0058] In an embodiment, referring to Figure 1 and Figure 2 , the handrail member 30 includes a connecting member 33, a first connecting segment 34, and a second connecting segment 35. The connecting member 33 is rotationally connected to the upright rod, and the rotation direction of the connecting member 33 is parallel to the left-right direction. The first connecting segment 34 and the second connecting segment 35 are fixedly connected to the two ends of the connecting member 33 in the longitudinal direction, and the first connecting segment 34 and the second connecting segment 35 are arranged at an obtuse angle.
[0059] In the embodiment, the rotating direction of the connecting piece 33 is parallel to the left-right direction, so that the handrail rod can better match the natural action of the user's hand. Compared with the right-angle connection of the first connecting section 34 and the second connecting section 35, the obtuse-angle connection of the first connecting section 34 and the second connecting section 35 to the connecting piece 33 in the embodiment can provide stronger anti-twisting performance, effectively preventing the handrail rod from bending or twisting under stress.
[0060] 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.
