[0039] The utility model provides a path simulation mechanism of elliptical machine for connecting in base.

[0040] In the embodiments of the utility model, please refer to 1, Figure 4 And Figure 7 The path simulation mechanism of elliptical machine 100 includes crank rocker assembly 110 and slider linkage assembly 120.

[0041] Crank rocker assembly 110 includes crank rocker assembly 110, crank rocker assembly 110 includes crank member 111, swing piece 112 and connecting rod 113;Swing piece 112 one end is used for rotatable connection in base 200, the other end is hinged in the front end of connecting rod 113;Crank member 111 one end is used for hinged in base 200, the other end is hinged in the position of connecting rod 113 in the rear side of swing piece 112;And

[0042] Slider linkage assembly 120, slider linkage assembly 120 includes foot pedal module 140 and step length extension mechanism 130, foot pedal module 140 slidably connected in connecting rod 113;Step length extension mechanism 130 includes first linkage 131, second linkage 133 and transmission member 132, foot pedal module 140 is sequentially transmission connection swing piece 112 through first linkage 131, transmission member 132 and second linkage 133;Transmission member 132 is rotatably connected with connecting rod 113, or, transmission member 132 is used for rotatably connected with base 200;The connecting point of second linkage 133 and transmission member 132 and the connecting point of first linkage 131 and transmission member 132 are spaced apart on transmission member 132, to push first linkage 131 linkage transmission member 132, second linkage 133 pushes swing piece 112 to swing relative to base 200 when foot pedal module 140 slides.

[0043] In the embodiment, the swing piece 112 and the curved piece 111 can be a rod structure or a disc structure, as long as they can be hingedly connected to the base 200 and the connecting rod 113, respectively. In order to reduce the weight and simplify the structure, and at the same time reduce the occupied space of the elliptical machine, the curved piece 111 and the swing piece 112 are rod structures. For the convenience of understanding, the curved piece 111 and the swing piece 112 are rod structures in the following exemplary description. The upper end of the swing piece 112 can be hingedly connected to the base 200, so that the whole swing rod is hung on the base 200. The curved piece 111, the base and the connecting rod 113, and the swing piece 112 and the connecting rod 113 can be hingedly connected through a rotating shaft.

[0044] The connecting rod 113 can be a straight rod, an arc-shaped rod with a concave middle part, or a bent rod with a front end bent upward, which is not limited here. The length and width of the connecting rod 113 can also be selected and designed according to actual needs. One end of the curved piece 111 is hingedly connected to the connecting rod 113 at a position behind the swing piece 112, so that the one end of the curved piece 111 can be hingedly connected to the rear end of the connecting rod 113 or the middle position of the connecting rod 113. Optionally, one end of the curved piece 111 is hingedly connected to the connecting rod 113 near the middle position, so that the connecting rod 113 has a connecting segment and an extension segment on the front and rear sides of the hinged position of the curved piece 111 and the connecting rod 113, and the foot pedal module 140 can reciprocate between the connecting segment and the extension segment. In this way, the foot pedal module 140 reciprocates on the front and rear sides of the hinged position of the curved piece 111 and the connecting rod 113, compared with the way that the foot pedal module 140 can only reciprocate on the connecting rod 113 between the swing piece 112 and the curved piece 111, the curved piece 111 is moved forward to make the structure of the whole elliptical machine more compact while achieving the same stride; and under the premise of the same occupied space (front and rear direction), the extension segment increases the front and rear reciprocating path of the foot pedal module 140, thereby increasing the stride of the whole elliptical machine.

[0045] The pedal module 140 is used to provide stable support for the user's feet, and when the user pedals the pedal module 140, the pedal module 140 can realize power transmission to convert the action into the power of the crank rocker assembly 110 movement. The pedal module 140 can be reciprocally and slidably connected to the connecting rod 113, and then the pedal and the connecting rod 113 can be slidably connected through the roller assembly or in the form of a linear guide rail, which is not specifically limited here. It can be understood that when the pedal module 140 and the connecting rod 113 are slidably connected through the roller assembly, the pedal is provided with at least two groups of rollers, which can be arranged between the pedal and the connecting rod 113 in the front and rear directions. The two groups of rollers can also be arranged at the front end of the pedal, respectively on the upper and lower sides of the connecting rod 113, and one of the rollers can also be arranged at the front end of the pedal and above the connecting rod 113, and the other roller can be arranged at the rear end of the pedal and below the connecting rod 113. Of course, the upper and lower rollers can also be arranged at the front and rear ends or the middle of the pedal, which is not specifically limited here. The pedal can only include a pedal plate, or can include a pedal plate, a front baffle, a rear baffle, a side baffle, etc., and the specific structure of the pedal module 140 is not limited here.

[0046] It can be understood that when the crank member 111, the swing member 112 and the connecting rod 113 are connected to the base 200, they form a structure similar to a crank rocker mechanism. The distance between the two hinge points of the crank member 111 is less than the distance between the two hinge points of the swing member 112 and the distance between the two hinge points of the connecting rod 113. In this way, the crank member 111 can make a circular motion around its hinge point with the base 200, and the swing member 112 can make a swing motion around its hinge point with the base 200. The stride lengthening mechanism 130 is drivingly connected to the pedal module 140 and the swing member 112. The first linkage 131, the transmission member 132 and the second linkage 133 are drivingly connected in sequence, and they can be connected by hinges or other transmission connections. The first linkage 131, the transmission member 132 and the second linkage 133 can be rod-shaped structures, so that they are hinged. Of course, one of the first linkage 131, the transmission member 132 and the second linkage 133 can be a disc-shaped member, and the other two can be rod-shaped structures. The structure and form of the first linkage 131, the transmission member 132 and the second linkage 133 can be many, which are not specifically limited here. It should be noted that the transmission member 132 is rotatably connected to the connecting rod 113 or the support, which is to avoid the overall displacement of the transmission member 132 without restraint, which causes the pedal module 140 to be unable to accurately push and pull the swing member 112 through the stride lengthening mechanism 130.

[0047] In actual use, the user steps on the foot pedal module 140 to push the foot pedal module 140 to reciprocate on the connecting rod 113, the foot pedal module 140 pushes the swing piece 112 to swing through the stride lengthening mechanism 130, so that the swing piece 112 can push and pull the connecting rod 113 to drive the crank piece 111 to make a circular motion, so that the movement track of the foot pedal module 140 is an ellipse after the crank piece 111 moves one circle, so as to make the movement track of the elliptical machine coincide with the ankle movement track of the human body when running naturally.

[0048] It can be understood that if the foot pedal module 140 is hinged to the swing piece 112 through a rod, the stride length of the foot pedal module 140 is basically equal to the swing amplitude of the swing piece 112. The stride lengthening mechanism 130 is provided, so that the stride lengthening mechanism 130 has three components of the first linkage 131, the second linkage 133 and the transmission piece 132, and the transmission piece 132 is rotationally connected to the machine base 200 or the connecting rod 113. When the foot pedal module 140 pushes the transmission piece 132 through the first linkage 131, the transmission piece 132 swings a certain amplitude relative to the connecting rod 113 or the machine base 200, and then pushes the swing piece 112 to swing through the second linkage 133. Therefore, the movement amplitude of the foot pedal module 140 is basically the swing amplitude of the transmission piece 132 plus the swing amplitude of the swing piece 112. Therefore, the foot pedal module 140 is drivingly connected to the swing piece 112 through the stride lengthening mechanism 130, which can greatly increase the movement amplitude without increasing the occupied space in the front-rear direction of the elliptical machine, thereby improving the exercise effect of the user using the elliptical machine.

[0049] The path simulation mechanism 100 of the elliptical machine comprises the crank rocker assembly 110 and the slider linkage assembly 120. The foot pedal module 140 is slidably connected to the connecting rod 113, and the foot pedal module 140 swings the swing piece 112 through the stride lengthening mechanism 130. The crank rocker mechanism and the slider mechanism are combined to make the foot pedal module 140 not only reciprocate but also make a circular motion with the crank piece 111, thereby realizing the elliptical track motion of the foot pedal module 140. The overall movement amplitude is large, the number of components of the path simulation mechanism 100 of the entire elliptical machine is small, the structure is compact, the overall volume and weight of the elliptical machine can be effectively reduced, the miniaturization and light weight of the elliptical machine are realized, the elliptical machine is more convenient for the user to place at home, and the storage space required when the elliptical machine is not used is smaller.

[0050] And by making the foot pedal module 140 sequentially driving connection swing piece 112 through the first linkage 131, transmission 132 and the second linkage 133 of stride lengthening mechanism 130, and making transmission 132 and connecting rod 113 rotationally connected or rotationally connected with base 200, the movement range of foot pedal module 140 is approximately the swing range of transmission 132 plus the swing range of swing piece 112. Thus, compared with the way that foot pedal module 140 directly drives swing piece 112 to swing through a push rod, the stride length of the entire elliptical machine can be greatly increased without additional space occupation in the front and rear directions, thereby improving the exercise effect of users using the elliptical machine. Therefore, the elliptical machine with the path simulation mechanism of the utility model can realize large stride length movement in a smaller use space, greatly improving the use performance of the product, and thereby effectively improving the product competitiveness.

[0051] Further, the first linkage 131, the transmission 132 and the second linkage 133 are all rod-shaped structures, the first linkage 131 and the second linkage 133 are rotationally connected with the transmission 132, and the first linkage 131 is rotationally connected with the foot pedal module 140, and the second linkage 133 is rotationally connected with the swing piece 112.

[0052] In the embodiment, the rotational connection between the two structures can be a shaft hinge. By making the first linkage 131, the transmission 132 and the second linkage 133 all rod-shaped structures, the volume and the occupied space of the entire stride lengthening mechanism 130 can be reduced, thereby more favorably reducing the weight of the entire elliptical machine. And by making the first linkage 131, the transmission 132 and the second linkage 133 all rotationally connected, the entire stride lengthening mechanism 130 is a connecting rod 113 mechanism, which can effectively reduce the manufacturing cost while making the transmission more reliable.

[0053] In the first embodiment, as shown in Figures 1 to 3 The stride lengthening mechanism 130 is arranged below the connecting rod 113; the two ends of the transmission 132 are rotationally connected with the connecting rod 113 and the first linkage 131, respectively, one end of the second linkage 133 is rotationally connected with the swing piece 112 at a position below the connecting rod 113, and the other end of the second linkage 133 is rotationally connected between the two end hinge points of the transmission 132.

[0054] In the embodiment, the transmission member 132 is arranged to rotate relative to the link rod 113, so as to prolong the moving path of the first linkage member 131 to push and pull the rocker 112, and increase the stride of the whole foot pedal module 140. The transmission member 132 is arranged to rotate relative to the link rod 113, which is more convenient than connecting the transmission member 132 to the frame. The whole stride lengthening mechanism 130 is arranged below the link rod 113, so that the stride lengthening mechanism 130 does not occupy the space above the link rod 113, and the foot pedal module 140 can move closer to the rocker 112, so as to make the whole machine mechanism more compact in the transverse direction and occupy less space.

[0055] Further, please refer to Figure 3 , the second linkage member 133 and the transmission member 132 are connected at point A, the transmission member 132 and the link rod 113 are connected at point B, and the transmission member 132 and the first linkage member 131 are connected at point C, wherein the distance between B and C is greater than the distance between A and B.

[0056] In the embodiment, since the point A is located between B and C, the closer the point A is to the point B (the connection point of the transmission member 132 and the link rod 113), the greater the distance between B and C, and the longer the force arm of the first linkage member 131 to the second linkage member 133 through the transmission member 132, so as to increase the stride of the whole stride lengthening mechanism 130 to the foot pedal module 140. Therefore, by making the distance between B and C greater than the distance between A and B, the connection point of the second linkage member 133 and the transmission member 132 is closer to the connection point of the transmission member 132 and the link rod 113, so as to increase the stride of the whole stride lengthening mechanism 130, to realize large stride without increasing the length of the link rod 113, and to make the whole elliptical machine meet the large stride movement while being miniaturized, and to improve the core competitiveness of the product.

[0057] Optionally, the distance between A and B is less than half of the distance between A and C. In this way, the distance between A and B is less than one third of the length of B and C, so that the transmission force arm of the transmission member 132 is close to the length of the whole transmission member 132, and the stride lengthening effect of the transmission member 132 is maximized.

[0058] In the second embodiment, as shown in Figures 4 to 6 , the first linkage member 131 is arranged below the link rod 113, and the second linkage member 133 is arranged above the link rod 113; the transmission member 132 is arranged to rotate relative to the link rod 113, the upper end of the transmission member 132 is arranged to rotate relative to one end of the second linkage member 133, and the lower end of the transmission member 132 is arranged to rotate relative to the first linkage member 131; the other end of the second linkage member 133 is arranged to rotate relative to the part of the rocker 112 above the link rod 113, and the other end of the first linkage member 131 is arranged to rotate relative to the part of the foot pedal module 140 below the link rod 113.

[0059] In the embodiment, the first linkage 131 is arranged below the link 113, so as to avoid the first linkage 131 occupying the space above the link 113 and affecting the movement of the foot pedal module 140, thereby making the overall structure more compact. A through hole can be formed in the link 113, so as to allow the transmission member 132 to pass through and rotate, and the transmission member 132 can be connected to the through hole in the link 113 in a rotatable manner by a rotating shaft. Alternatively, the transmission member 132 can be rotatably connected to the side wall of the link 113. By rotating the transmission member 132 relative to the link 113, the movement path of the first linkage 131 pushing and pulling the swing member 112 can be extended, thereby increasing the stride of the entire foot pedal module 140. By rotatably connecting the transmission member 132 to the link 113, the extension length of the transmission member 132 can be effectively shortened compared to connecting the transmission member 132 to the frame, thereby reducing the occupied space of the transmission member 132 above the link 113, and making the overall structure more compact.

[0060] In addition, the middle part of the transmission member 132 is rotatably connected to the link 113, and the upper and lower ends of the transmission member 132 are rotatably connected to the second linkage 133 and the first linkage 131, respectively. In this way, the transmission arm of the entire transmission member 132 is maximized (almost equal to the length of the transmission member 132), thereby maximizing the stride increasing effect of the transmission member 132, and maximizing the stride that can be extended by the stride extension mechanism 130 without increasing the length of the transmission member 132.

[0061] Further, please refer to Figure 6 , the second linkage 133 and the transmission member 132 are connected at point A, the transmission member 132 and the link 113 are connected at point B, and the transmission member 132 and the first linkage 131 are connected at point C, wherein the distance between B and C is greater than the distance between A and B. It can be understood that since the AB segment is above the link 113, if the AB segment is too long, it will occupy too much space above the link 113, and even may collide with the user's knees. By making the distance between B and C greater than the distance between A and B, the most space below the link 113 and the small part of the space above the link 113 are fully utilized, without increasing the height of the elliptical machine and without occupying too much space above the link 113, thereby avoiding the knees of the user colliding with the part of the transmission member 132 extending above the link 113 during movement, to improve the safety of the product in use.

[0062] Optionally, the ratio of BC to AB is greater than or equal to 2 and less than or equal to 3. In this way, nearly two-thirds of the transmission member 132 is located below the connecting rod 113 and nearly one-third of the transmission member 132 is located above the connecting rod 113, which reduces the space occupied by the transmission member 132 above the connecting rod 113 as much as possible without increasing the height of the elliptical machine, which makes the structure above the connecting rod 113 more simple while improving the safety of the product.

[0063] In a third embodiment, as shown in FIG. 3, the first linkage member 131 is arranged below the connecting rod 113, the second linkage member 133 is arranged above the connecting rod 113, the upper end of the transmission member 132 is rotatably connected to the machine base 200, the lower end of the transmission member 132 is rotatably connected to the first linkage member 131, and one end of the second linkage member 133 is rotatably connected between the two end hinge points of the transmission member 132. Figures 7 to 9

[0064] In this embodiment, the first linkage member 131 is arranged below the connecting rod 113, which avoids the first linkage member 131 occupying space above the connecting rod 113 and affecting the movement of the foot pedal module 140, so that the overall structure is more compact. A through hole can be formed in the connecting rod 113 for the transmission member 132 to pass through and swing.

[0065] By rotating the transmission member 132 relative to the machine base 200, the movement path of the first linkage member 131 pushing and pulling the swing member 112 can be extended, so that the stride of the entire foot pedal module 140 can be increased. The first linkage member 131 is arranged below the connecting rod 113 and the second linkage member 133 is arranged above the connecting rod 113. In this way, the space occupied by the entire stride extension mechanism 130 below the connecting rod 113 can be reduced, so that the entire elliptical machine is more compact in the longitudinal direction and occupies less height space.

[0066] In addition, since the upper end of the transmission member 132 is connected to the machine base 200, the overall length of the transmission member 132 is relatively long, so that the length of the transmission member 132 can be fully utilized, the distance between the hinge point of the first linkage member 131 and the hinge point of the second linkage member 133 to the transmission member 132 can be set to be larger, so that the transmission arm of the entire transmission member 132 can be set to be larger, so that the stride of the entire stride extension mechanism 130 can be extended more. The position of the second linkage member 133 hinged to the transmission member 132 can be designed and adjusted according to the actual required stride, which is not specifically limited here.

[0067] ​Furthermore, one end of the second linkage 133 is rotatably connected to the connection between the rocker 112 and the connecting rod 113. In this way, the second linkage 133, the rocker 112 and the connecting rod 113 are rotatably connected at the same point, which simplifies the connection structure and the number of parts, and makes the entire elliptical machine path simulation mechanism 100 more concise.

[0068] Furthermore, such as Figure 9 As shown, the rocker arm 112 and the transmission arm 132 are arranged side by side along the length of the connecting rod 113. The first linkage arm 131 and the transmission arm 132 are hinged at point D, the transmission arm 132 and the second linkage arm 133 are hinged at point E, and the second linkage arm 133 and the rocker arm 112 are hinged at point F. The distance between E and F is greater than or equal to half the distance between DE and D, and less than or equal to twice the distance between DE and D.

[0069] Understandably, the rocker element 112 is positioned side-by-side in front of the transmission element 132. By making the distance EF between the two hinge points of the second linkage element 133 smaller than the distance DE between the hinge points of the first linkage element 131 and the transmission element 132 and the hinge points of the second linkage element 133, the length of the first linkage element 131 can be set shorter. This allows the stride extension mechanism 130 to effectively extend the stride of the elliptical machine while making the rocker element 112 and the transmission element 132 more compact, thus facilitating the miniaturization of the elliptical machine. At the same time, the distance between EF can also be greater than the distance between DE, but by constraining the distance between EF to be less than or equal to twice the distance between DE, the pedal module 140 can achieve a relatively ideal elliptical trajectory.

[0070] In another embodiment, the upper end of the transmission member 132 is rotatably connected to the base 200, and the lower end of the transmission member 132 is rotatably connected to the first linkage member 131. When the rocker member 112 and the transmission member 132 are in a vertical state, they are arranged overlapping in the length direction of the connecting rod 113. The rocker member 112 and the transmission member 132 are slidably connected between the hinge points at both ends of the transmission member 132.

[0071] In this embodiment, the rocker element 112 and the transmission element 132 overlap in a vertical state, that is, the rocker element 112 and the transmission element 132 are arranged side by side. This reduces the space occupied by the rocker element 112 and the transmission element 132 along the length of the connecting rod 113, resulting in a smaller front-to-back space occupied by the entire stride extension mechanism, thus making the entire elliptical machine structure more compact and smaller in size. It is understood that the hinge point between the rocker element 112 and the transmission element 132 can slide between the two hinge points of the transmission element 132. In this case, the second linkage element 133 is a sliding pin that enables the sliding connection between the rocker element 112 and the transmission element 132.

[0072] The utility model also proposes an elliptical machine, please refer to Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 、 Figures 8 to 9 The elliptical machine includes a base 200 and two sets of path simulation mechanisms 100 of the elliptical machine, the specific structure of the path simulation mechanism 100 of the elliptical machine refers to the above embodiment, the two sets of path simulation mechanisms 100 of the elliptical machine are arranged on opposite sides of the base 200 transversely, one end of the swing piece 112 of the path simulation mechanism 100 of the elliptical machine is rotatably connected to the front end of the base 200, and one end of the bending piece 111 is hingedly connected to the rear end of the base 200, since the elliptical machine adopts all the technical solutions of the above embodiments, at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. The foot pedal module 140 of the two sets of path simulation mechanisms 100 of the elliptical machine is used for the user's two feet to step on respectively. Generally, the bending piece 111 of the two sets of path simulation mechanisms 100 of the elliptical machine is fixedly connected. In this way, the user can perform continuous and cyclic stepping actions through the elliptical machine, achieving the exercise effect.

[0073] In an embodiment, the elliptical machine further includes a handrail 300 and an amplitude reduction mechanism 400, the amplitude reduction mechanism 400 has a connecting point that can move up and down, the handrail 300 is drivingly connected to the swing piece 112 through the amplitude reduction mechanism 400, and the swing piece 112 pushes the connecting point of the amplitude reduction mechanism 400 to move up and down, so that the swing amplitude of the handrail 300 is smaller than that of the swing piece 112.

[0074] It can be understood that the elliptical machine of the above embodiment can also not be provided with the handrail 300, only realizing leg movement, and the overall occupied space will be smaller. In the embodiment, the elliptical machine includes the handrail 300, and the handrail 300 is linked with the swing piece 112, so that the user can perform synchronous movement of the arms through the handrail 300 while moving the legs, realizing full-body movement and improving the movement effect of the user.

[0075] In the embodiment, the embodiment of the reduction mechanism 400 can have many, for example, the reduction mechanism 400 can be various connecting rod 113 mechanism, at this time the connecting point that can move up and down is the hinge point between the connecting rod 113. The reduction mechanism 400 can also be a pin shaft and a waist hole structure arranged between the handrail 300 and the swing piece 112 to cooperate with each other, at this time the connecting point is located on the pin shaft or the waist hole that can move up and down. The reduction mechanism 400 can also be a gear structure, a belt pulley structure, and the connecting point is a certain point on the gear structure and a certain point on the belt. By setting the reduction mechanism 400, the handrail 300 is not directly connected with the swing piece 112, so that the swing piece 112 first pushes the connecting point on the reduction mechanism 400 to move upward or downward, and then drives the handrail 300 to swing, so that the swing amplitude of the handrail 300 is smaller than the swing amplitude of the swing piece 112 through the reduction mechanism 400, so that the elliptical machine effectively reduces the swing amplitude of the handrail 300 while realizing large amplitude, so as to improve the user's comfort.
