Description

Technical Field

[0001] This application relates to the field of training equipment technology, and in particular to an elliptical machine. Background Technology

[0002] The elliptical trainer is a comprehensive aerobic exercise device that simulates the natural movements of walking or running, but avoids the high impact of running, thus gaining popularity among fitness enthusiasts. An elliptical trainer includes a foot pedal mechanism, a swing arm, a crank arm, and a connecting rod linking the swing arm and crank arm. The swing arm oscillates around a pivot point, and the crank arm performs circular motions around the pivot point. The foot pedal mechanism is mounted on the connecting rod. To enhance the exercise effect, current elliptical trainers also feature handrails fixedly connected to the swing arm, allowing users to swing their arms synchronously while using the trainer. However, because elliptical trainers aim for a large stride to improve fitness results, the current structure of elliptical trainers requires increasing the swing amplitude of the swing arm to achieve this. This results in a larger overall usable space for the elliptical trainer and a larger swing angle for the handrails, significantly reducing user comfort.

[0042] The utility model provides an elliptical machine.

[0043] In the embodiments of the utility model, please refer to Figures 1-2 , 5-6, 9-10, the elliptical machine includes machine body 100, transmission mechanism 300, foot pedal assembly 400 and switching mechanism 500;

[0044] Transmission mechanism 300 includes first swing piece 310, support connecting rod 320, crank member 330 and gyro wheel 340, one end of first swing piece 310 is rotatably connected with machine body 100, the other end of first swing piece 310 is rotatably connected with the front end of support connecting rod 320, and the rear part of support connecting rod 320 is circumferentially rotatably connected to machine body 100 through crank member 330;Gyro wheel 340 is connected to support connecting rod 320;

[0045] The pedal assembly 400 comprises a second swing piece 410, a pedal connecting rod 420, and a pedal plate 430 fixedly mounted on the pedal connecting rod 420, one end of the second swing piece 410 is connected with the front end of the pedal connecting rod 420, and the second swing piece 410 is rotatably connected to the machine body 100 or the supporting connecting rod 320, and the second swing piece 410 is arranged side by side with the first swing piece 310 in the front-back direction; the pedal connecting rod 420 is slidably connected to the roller 340;

[0046] The switching mechanism 500 is drivingly connected with the first swing piece 310 and the second swing piece 410.

[0047] In the embodiment, the machine body 100 is used to provide installation and support for the transmission mechanism 300, the pedal assembly 400, and the like, and the overall frame of the machine body 100 can be various, which can be designed according to actual needs, for example, the machine body 100 can be designed in the form of a bicycle frame or a scooter frame, and the shape and structure of the machine body 100 are not limited here. It can be understood that the transmission mechanism 300, the pedal assembly 400, and the switching mechanism 500 each have two groups to correspond to the left and right feet of the user exercising.

[0048] It should be noted that the first swing piece 310, the supporting connecting rod 320, and the crank piece 330 form a crank rocker mechanism as a whole with the machine body 100. Then the definition of the crank piece 330 is that in the crank rocker mechanism, it can make a whole rotation. The definition of the swing piece is that it can only make a swing movement within a certain range, and cannot make a whole rotation. The crank piece 330, the first swing piece 310, and the second swing piece 410 can be a rod-shaped structure or a disc-shaped structure. In order to reduce the weight, simplify the structure, and reduce the occupied space of the elliptical machine, the crank piece 330, the first swing piece 310, and the second swing piece 410 can be rod-shaped structures. For the convenience of understanding, the crank piece 330, the first swing piece 310, and the second swing piece 410 are exemplarily described as rod-shaped structures in the following.

[0049] The pedal assembly 400 comprises the second swing piece 410 and the pedal connecting rod 420, and the pedal connecting rod 420 is slidably connected to the roller 340 arranged on the supporting connecting rod 320. Then the second swing piece 410 and the pedal connecting rod 420 form a rocker slider mechanism as a whole with the supporting connecting rod 320 (the machine body 100) through the roller 340. That is, the second swing piece 410 can make a front-back swing movement relative to the connecting rod and the machine body 100, and the pedal connecting rod 420 provided with the pedal plate 430 can make a front-back sliding movement relative to the supporting connecting rod 320 through the roller 340. In this way, the pedal assembly 400 can make a crank rocker movement with the transmission mechanism 300, and the pedal plate 430 can also make a rocker slider movement relative to the connecting rod.

[0050] The first swing piece 310 and the second swing piece 410 are arranged side by side in the front-rear direction, and when the first swing piece 310 and the second swing piece 410 are in a rod-shaped structure, the first swing piece 310 and the second swing piece 410 extend substantially in the up-down direction. The lower end of the first swing piece 310 is rotatably connected to the support link 320, and the lower end of the second swing piece 410 is connected to the front end of the foot pedal link 420. Since the foot pedal link 420 extends substantially in the front-rear direction, the lower end of the second swing piece 410 and the front end of the foot pedal link 420 can be connected by additionally arranging an inclined rod, or the front end of the foot pedal link 420 can be bent downward to be connected to the lower end of the second swing piece 410.

[0051] The rotatable connection between each of the above components can be a hinged connection through a rotating shaft and a shaft hole. The support link 320 and the foot pedal link 420 can be straight rods, or can be designed as bent rods or the like according to actual needs, and are not specifically limited herein. The length and width of the support link 320 and the foot pedal link 420 can also be selected and designed according to actual needs. The rear part of the support link 320 is rotatably connected to the curved piece 330, and the rear end of the support link 320 or a position adjacent to the rear end of the support link 320 can be rotatably connected to the curved piece 330. The roller 340 can be fixedly connected to the support link 320, so that the foot pedal link 420 slides forward and backward on the rolling surface of the roller 340; of course, the roller 340 can also be rotatably connected to the support link 320, so that the foot pedal link 420 slides forward and backward on the rolling surface of the roller 340 while driving the roller 340 to roll, and the sliding of the foot pedal link 420 relative to the support link 320 is more flexible and smooth.

[0052] By arranging the roller 340 on the support link 320, the foot pedal 430 slides forward and backward on the roller 340 through the foot pedal link 420, and compared with the mode in which the foot pedal 430 directly slides on the support link 320 through the roller 340, the foot pedal 430 is not limited by the connecting point of the support link 320 and the curved piece 330, so that the foot pedal 430 can slide on both sides of the curved piece 330, rather than only on the front side of the curved piece 330, and thus the curved piece 330 can be moved forward while achieving the same stride, so that the structure of the entire elliptical machine is more compact; and under the premise of the same occupied space (in the front-rear direction), since the foot pedal link 420 can drive the foot pedal 430 to move on the rear side of the roller 340, the forward and backward reciprocating sliding path of the foot pedal 430 is increased, and thus the stride of the entire elliptical machine is increased. The elliptical machine of the present application can realize large-stride movement while occupying less space, greatly improving the use performance of the product, and thus effectively improving the competitiveness of the product.

[0053] The transmission mechanism 500 is used to drive connect the first swing piece 310 and the second swing piece 410, and the structure of the transmission mechanism 500 can be various, for example, the transmission mechanism 500 can be a single connecting rod, a plurality of connecting rods or other transmission members, etc., as long as the second swing piece 410 can drive push and pull the first swing piece 310, and the specific structure of the transmission mechanism 500 is not limited here. The foot pedal 430 is used to provide stable support for the user's feet, and when the user steps on the foot pedal 430, the foot pedal 430 can realize power transmission to convert the action into the power of the movement of the transmission mechanism 300. The foot pedal 430 can be fixedly installed on the foot pedal connecting rod 420 by screws, welding or the like, and compared with the mode that the foot pedal 430 is directly connected to the support connecting rod 320 through the rollers 340 or the linear guide rails, the foot pedal 430 fixedly installed on the foot pedal connecting rod 420 can simplify the structure and installation of the foot pedal 430. The foot pedal 430 can only include a pedal, or can include a pedal, a front baffle, a rear baffle, a side baffle, etc., and the specific structure of the foot pedal 430 is not limited here.

[0054] It should be noted that when the foot pedal connecting rod 420 is directly connected to the first swing piece 310, if the stride of the foot pedal 430 is to be increased, the swing range of the first swing piece 310 needs to be increased, so that on the one hand, the front and rear use space of the entire elliptical machine is increased, and on the other hand, when the first swing piece 310 is connected to the handrail 200, the front and rear swing range of the entire handrail 200 is too large, resulting in reduced user comfort. By arranging the second swing piece 410, the first swing piece 310 and the second swing piece 410 are arranged side by side in the front and rear direction, and the first swing piece 310 and the second swing piece 410 are driving connected through the transmission mechanism 500, so when the user's foot steps on the foot pedal 430 and an initial force is applied to the foot pedal 430, the foot pedal connecting rod 420 first drives the second swing piece 410 to swing, and then drives the first swing piece 310 to rotate through the transmission mechanism 500, thereby realizing the circumferential movement of the crank member 330; the movement range of the foot pedal 430 is approximately the swing range of the second swing piece 410 plus the swing range of the transmission mechanism 500. In other words, compared with the mode that the foot pedal connecting rod 420 is directly connected to the first swing piece 310, the movement path of the foot pedal 430 can be effectively lengthened without additional or excessive increase in the swing range of the first swing piece 310, so that the elliptical machine can increase the stride while reducing the front and rear movement space occupied by the entire elliptical machine, and reducing the swing range of the handrail 200 fixedly connected to the first swing piece 310.

[0055] The utility model elliptical machine through setting up gyro wheel 340 on support connecting rod 320, make footboard 430 through footboard connecting rod 420 can be connected in roll wheel 340 before and after sliding, compared with the mode of footboard 430 direct sliding connection in support connecting rod 320, will not be limited by the connecting point of support connecting rod 320 and bending member 330, thereby make footboard 430 can slide in the front and back sides of bending member 330, not only in the front side of bending member 330, so, under the premise of same occupied space (front and back direction), since footboard connecting rod 420 can drive footboard 430 move in gyro wheel 340 and the rear side of bending member 330, then increase the front and back reciprocating sliding path of footboard 430, and then increase the stride of whole elliptical machine.

[0056] Meanwhile, make footboard connecting rod 420 rotatable connection with machine body 100 or support connecting rod 320 through second swing piece 410, and make second swing piece 410 and first swing piece 310 set up side by side in front and back direction, second swing piece 410 drive connection first swing piece 310 through adapter mechanism 500, when the foot of user steps on footboard 430 and gives footboard 430 an initial force to the front or rear, footboard connecting rod 420 first drive second swing piece 410 swing, then drive first swing piece 310 rotate through adapter mechanism 500, and then realize the circumferential motion of bending member 330, and the movement amplitude of footboard 430 is approximately the swing of second swing piece 410 plus the swing of adapter mechanism 500. Thus, compared with the mode that footboard connecting rod 420 is directly connected to first swing piece 310, while not additional increase the occupied space of elliptical machine in front and back direction, effectively prolong the moving path of footboard 430, that is, effectively increase the movement stride of whole elliptical machine, thereby can improve the exercise effect of user using elliptical machine. In addition, in the scheme that elliptical machine has handrail 200 fixedly connected with first swing piece 310, while not excessively increase the swing of handrail 200 when increase the movement stride of elliptical machine, thereby make the user's use comfort and exercise effect better.

[0057] Further, the second swing member 410 is arranged behind the first swing member 310. It can be understood that the human body has a comfortable range of motion stride. In actual use, since the support link 320 has a long enough distance, and the foot pedal 430 reciprocates on the front and back sides of the crank member 330, the foot pedal 430 almost cannot move to the position where the front end of the support link 320 is close to the first swing member 310, so that the second swing member 410 is arranged behind the first swing member 310, the space of the front end of the support link 320 can be fully utilized for the swing of the second swing member 410, so that the overall structure is more compact, the use of materials can be reduced, and the weight of the entire elliptical machine can be avoided. In another embodiment, the second swing member 410 can also be arranged in front of the first swing member 310. In this way, the first swing member 310 and the second swing member 410 are arranged side by side in the front-back direction, and the operation reliability of the entire elliptical machine movement mechanism can be ensured.

[0058] Further, the connecting point of the crank member 330 and the support link 320 and the axis of the roller 340 are arranged in the front-back direction. That is, the roller 340 is arranged eccentrically relative to the connecting point of the crank member 330 and the support link 320, and the roller 340 can be arranged on the front side of the connecting point of the crank member 330 and the support link 320, or on the rear side of the connecting point of the crank member 330 and the support link 320.

[0059] It can be understood that the connecting point of the crank member 330 and the support link 320 and the axis of the roller 340 are arranged in the front-back direction, so that the distance from the connecting point of the crank member 330 and the machine body 100 to the axis of the roller 340 is greater than the distance between the connecting point of the crank member 330 and the machine body 100 and the connecting point of the crank member 330 and the support link 320. In this way, the rotating radius of the axis of the roller 340 can be increased, and compared with the scheme in which the connecting point of the roller 340 and the support link 320 and the connecting point of the crank member 330 and the support link are coaxial, the front-back moving distance of the entire foot pedal 430 relative to the ground can be increased, and thus the motion stride of the foot pedal 430 can be increased to a certain extent.

[0060] Further, as shown in Figures 5-12 The support link 320 has a main body segment 321 on the front side of the crank member 330 and an extension segment 322 on the rear side of the crank member 330, and the roller 340 is connected to the rear end of the extension segment 322.

[0061] In the embodiment, the support link 320 has an extension 322 at the rear side of the curved member 330. Compared with the mode that the rear end of the support link 320 is connected with the curved member 330, the curved member 330 is moved forward in the same stride, the structure of the whole elliptical machine is more compact. Under the premise of the same space (front and back direction), the extension increases the front and back reciprocating sliding path of the pedal module, and further increases the stride of the whole elliptical machine. Therefore, the elliptical machine with the path simulation mechanism of the utility model can realize large stride movement in smaller space, greatly improves the use performance of the product, and further effectively improves the product competitiveness.

[0062] In an embodiment, please refer to Figure 1 , Figure 5 and Figure 9 The roller 340 is installed on the outer side wall of the support link 320, and the second swing member 410 is located on the outer side of the support link 320. The roller 340 and the second swing member 410 are located on the outer side of the support link 320, compared with the mode that the roller 340 is installed on the top wall of the support link 320, the second swing member 410 does not need to be provided with a hole on the support link 320, which can simplify the forming manufacturing process of the elliptical machine and reduce the overall production cost. Compared with the mode that the roller 340 and the second swing member 410 are arranged on the inner side of the support link 320, the pedal plate 430 is far away from the swing member, which can effectively avoid the collision or interference during movement and improve the use safety.

[0063] In an embodiment, as shown in Figures 1-12 The pedal link 420 includes a first section 421 and a second section 422 connected with each other, the front end of the first section 421 is rotatably connected with the lower end of the second swing member 410, and the first section 421 is inclined from front to back and upward, the pedal plate 430 is fixedly connected with the second section 422, and the second section 422 is slidably connected with the roller 340.

[0064] In the embodiment, the second section 422 of the pedal link 420 extends in the front and back direction, and the first section 421 is inclined from front to back and upward, so that the pedal link 420 as a whole has a front end downwardly bent rod structure. Compared with the mode that the pedal link 420 is a straight rod, the additional inclined link is not needed, the distance between the connection point of the second swing member 410 and the pedal link 420 and the connection point of the second swing member 410 and the adapter mechanism 500 can be increased in the structure more compact and the space occupied is smaller, and the requirement of stride extension can be met.

[0065] In an embodiment, please refer to Figure 1 , Figure 5 and Figure 9The switching mechanism 500 is a linkage, and two ends of the linkage are rotatably connected with the first swing 310 and the second swing 410 respectively. The switching mechanism is the linkage, which simplifies the switching mechanism 500 under the premise of meeting the linkage requirement, and thus effectively reduces the cost of the whole elliptical machine. It can be understood that when the user's foot moves up and down on the foot pedal 430, the foot pedal linkage 420 slides forward and backward relative to the support linkage 320 through the roller 340, the foot pedal linkage 420 drives the second swing 410 to swing relative to the machine body 100 or the linkage, and then drives the linkage to swing to push and pull the first swing 310 to swing forward and backward, and thus drives the support linkage 320 to drive the crank member 330 to move in a circle, so as to realize the elliptical trajectory movement.

[0066] In the first embodiment, as shown in Figures 1-4 , the upper end of the second swing 410 is rotatably connected with the machine body 100, and specifically as shown in Figure 3 , the connection point of the second swing 410 with the machine body is point A, the connection point of the linkage with the second swing 410 is point B, and the connection point of the foot pedal linkage 420 with the second swing 410 is point C, and the distance between A and B is less than the distance between B and C.

[0067] In the first embodiment, the upper end of the second swing 410 is rotatably connected with the machine body 100, and thus the second swing 410 is equivalent to a rocker. The second swing 410 and the first swing 310 form a double rocker structure as a whole, which can ensure the stability of the whole linkage system. By making the distance between A and B less than the distance between B and C, that is, the distance between the connection point of the linkage with the second swing 410 and the connection point of the foot pedal linkage 420 with the second swing 410 is greater than the distance between the connection point of the linkage with the second swing 410 and the connection point of the second swing 410 with the machine body 100. In this way, the distance between the connection point of the linkage with the second swing 410 and the connection point of the foot pedal linkage 420 with the second swing 410 can be lengthened, and the force arm of the foot pedal linkage 420 to the switching mechanism 500 is longer. The second swing 410 only swings to a large amplitude when the switching mechanism 500 drives the first swing 310 to swing, so that the stride of the whole elliptical machine is increased.

[0068] In the second embodiment, please refer to Figures 5-8 , the middle part of the second swing 410 is rotatably connected with the support linkage 320 at point D, the upper end of the second swing 410 is rotatably connected with one end of the linkage at point E, and the lower end of the second swing 410 is rotatably connected with the foot pedal linkage 420 at point F, and the distance between D and F is greater than the distance between D and E.

[0069] In the embodiment, the second swing 410 is rotatably connected to the support link 320, which is more convenient than connecting the second swing 410 to the body 100. The middle part of the second swing 410 is rotatably connected to the support link 320, one end of the linkage rod is connected to the upper end of the second swing 410, and the linkage rod is above the support link 320, so that the space occupied by the second swing 410 and the linkage rod below the support link 320 is reduced, and the whole elliptical machine is more compact in the longitudinal direction and occupies less space in the height direction. The distance DE is greater than the distance DF, so that the distance between the connection point of the linkage rod and the second swing 410 and the connection point of the foot pedal link 420 and the second swing 410 is extended, and the force arm of the foot pedal link 420 to the switching mechanism 500 is longer. The first swing 310 is swung only when the second swing 410 swings to a large amplitude, so that the stride of the whole elliptical machine is increased.

[0070] Alternatively, the hinge points between the linkage rod, the first swing 310, the support link 320, and the second swing 320 form a non-parallelogram, so that the dead point of the second swing 410 and the linkage rod during movement is avoided, and the movement reliability of the whole elliptical machine is ensured.

[0071] In the third embodiment, please refer to Figures 9-12 The upper end of the second swing 410 is rotatably connected to the support link 320 at the point D', one end of the linkage rod is rotatably connected to the middle part of the second swing 410 at the point E', and the lower end of the second swing 410 and the front end of the foot pedal link 420 are rotatably connected at the point F', wherein the distance E'F' is greater than the distance D'E'.

[0072] In this way, the second swing 410 and the linkage rod are arranged below the support link 320, so that the second swing 410 and the linkage rod do not occupy the space above the support link 320, and the whole machine mechanism is more compact in the transverse direction and occupies less space. The second swing 410 is rotatably connected to the support link 320, which is more convenient than connecting the second swing 410 to the body 100. The distance E'F' is greater than the distance D'E', so that the distance between the connection point of the linkage rod and the second swing 410 and the connection point of the foot pedal link 420 and the second swing 410 is extended, and the force arm of the foot pedal link 420 to the switching mechanism 500 is longer. The first swing 310 is swung only when the second swing 410 swings to a large amplitude, so that the stride of the whole elliptical machine is increased.

[0073] In an embodiment, as Figures 1-4As shown, the elliptical machine further comprises a handrail 200, which is detachably and fixedly connected to the first swing piece 310. By arranging the handrail 200 fixedly connected to the first swing piece 310, the user can perform synchronous movement of the arms through the handrail 200 while performing leg movement, so as to realize full-body movement and improve the movement effect of the user.

[0074] Moreover, since the foot pedal connecting rod 420 is rotatably connected to the machine body 100 or the supporting connecting rod 320 through the second swing piece 410, and the second swing piece 410 is arranged side by side with the first swing piece 310 in the front-rear direction, the second swing piece 410 is drivingly connected to the first swing piece 310 through the adapter mechanism 500. Compared with the mode that the foot pedal connecting rod 420 is directly connected to the first swing piece 310, the movement stride of the elliptical machine is increased without additional or excessive increase of the swing range of the first swing piece 310, so as to avoid excessive increase of the swing range of the handrail 200, thereby making the user's use comfort and exercise effect better.

[0075] The handrail 200 is detachably connected to the first swing piece 310 through plug-in, screw fixation or other modes. Moreover, since the above-mentioned structure can increase the movement stride of the elliptical machine without excessive increase of the swing range of the handrail 200. Thus, when the handrail 200 is connected to the first swing piece 310, the dismounting point of the handrail 200 is lowered, thereby reducing the storage size and packaging size of the elliptical machine with the handrail 200, and further reducing the storage and transportation cost.

[0076] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but 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 that: 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.
