Description

Technical Field

[0001] The utility model relates to the field of rowing machines, in particular to a magnetically controlled resistance rowing machine. Background Art

[0002] A rowing machine is a fitness equipment that imitates the action of rowing. It achieves a certain exercise effect by pulling an impeller set in a liquid through a rope. In the existing technology, there are two types of rowing machines. One uses liquid and impellers to provide a certain resistance, and the other provides a certain resistance through a magnetic control structure. When using a magnetic control structure to provide resistance, an aluminum layer is generally used to cut the magnetic lines of force to generate eddy currents, thereby forming resistance. In the existing technology, the aluminum layer is generally directly set on the rotating structure, such as the outside of the rope reel, or an aluminum ring is set separately. At this time, resistance is only provided by the aluminum ring and the magnetic control structure. During use, the resistance stability is poor, which affects the user experience.

[0022] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time. In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only."

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] like Figures 1 to 3As shown, a magnetically controlled resistance rowing machine is characterized in that it includes a bracket 1, the bracket 1 is provided with a resistor 2, the resistor 2 includes an axis 21, and is rotatably connected to the bracket 1 through a bearing, a small wheel 22 is provided on the outer side of the axis 21 through a bearing, a large wheel 23 is provided on the side of the bracket 1 through a rotating shaft and a bearing, the large wheel 23 and the small wheel 22 are connected by a conveyor belt, a spring structure 24 and a rope fixing wheel 25 are provided on the outer side of the rotating shaft, a flywheel 26 is provided at the end of the axis 21, an aluminum ring 27 is provided on the edge of the flywheel 26, and a corresponding magnetic control component is provided on the outer side of the aluminum ring 27.

[0026] After the flywheel 26 is combined with the magnetic control component, the rotation speed of the flywheel 26 can be controlled under the action of the magnetic control component. At this time, the flywheel 26 can provide a certain resistance, thereby affecting the rotation of the rope fixing wheel 25. At the same time, during the rotation of the flywheel 26, the rotational inertia is large. The flywheel 26 can make the rope fixing wheel 25 more stable during the rotation process, thereby making the rowing machine more stable during use.

[0027] At this time, in order to fix the pull rope fixing wheel 25, in this embodiment, the bracket 1 includes a first fixing plate 11 and a second fixing plate 12 arranged at intervals, and the rotating shaft is rotatably connected to the first fixing plate 11 and the second fixing plate 12 through a bearing. The pull rope fixing wheel 25 is located between the first fixing plate 11 and the second fixing plate 12, and the clockwork structure 24 and the large wheel 23 are fixed on the outside of the rotating shaft. The first fixing plate 11 and the second fixing plate 12 are arranged in parallel and spaced apart. A spring structure 24 is provided at the position of the first fixing plate 11 through a bearing seat and a bearing, and a large wheel 23 is provided at the position of the second fixing plate 12 through a bearing seat and a bearing. In this way, the spring structure 24 and the large wheel 23 are respectively arranged at the outer positions of the first fixing plate 11 and the second fixing plate 12, and are connected by a rotating shaft. At the same time, the rope fixing wheel 25 is located between the first fixing plate 11 and the second fixing plate 12. The rope fixing wheel 25, the spring structure 24 and the large wheel 23 on the outer side of the rotating shaft are basically symmetrically distributed. During the rotation of the rotating shaft, the rope fixing wheel 25, the spring structure 24 and the large wheel 23, the rotation will be relatively smooth, so that the rowing machine will shake less during use and the overall stability is relatively good. At the same time, the rope fixing wheel 25 is fixed to the rope fixing wheel 25 at the outer position of the rotating shaft between the first fixing plate 11 and the second fixing plate 12. During the rotation of the rope fixing wheel 25, the rotating shaft rotates synchronously.

[0028] At this time, the clockwork structure 24 adopts the existing technical solution, which mainly drives the mechanical device to operate by storing and releasing elastic potential energy, that is, after pulling the rope outside and making the rope fixing wheel 25 rotate a certain circle, the clockwork structure 24 can restore the rope fixing wheel 25 to its original position.

[0029] Furthermore, in order to connect the drawstring to the drawstring fixing wheel 25, in this embodiment, the rowing machine further includes a housing 3. A pulley 251 is provided on the upper side of the drawstring fixing wheel 25. The pulley 251 is rotatably fixed to the inner side of the housing 3. The housing 3 has an opening corresponding to the position of the pulley 251. The drawstring wrapped around the outer side of the drawstring fixing wheel 25 extends to the outside of the housing 3 at the opening. The drawstring wrapped around the outer side of the drawstring fixing wheel 25 passes around the pulley 251 and extends to the outside of the housing 3. It is then fixed to the handle outside the housing 3. During use, the drawstring is pulled by the handle, thereby rotating the drawstring fixing wheel 25 and the rotating shaft, thereby achieving the corresponding movement.

[0030] To generate electricity during exercise, the rowing machine, in this embodiment, also includes a power generation structure 4. This structure comprises an annular magnetic ring 41 positioned inside the flywheel 26. A coil assembly 42 is fixed to the side of the bracket 1, positioned inside the annular magnetic ring 41, with a gap between the annular magnetic ring 41 and the coil assembly 42. The large wheel 23 is connected to the small wheel 22 via a conveyor belt. As the large wheel 23 rotates, the small wheel 22 and its corresponding shaft 21 also rotate synchronously, driving the flywheel 26. This in turn also rotates the annular magnetic ring 41 fixed to the side of the flywheel 26. As the annular magnetic ring 41 rotates, the coil assembly 42 remains stationary, resulting in relative motion, which generates current and generates electricity. Because the annular magnetic ring 41 is fixed to the side of the flywheel, it acts as a component, increasing the overall weight of the flywheel and thereby increasing its moment of inertia during rotation.

[0031] To ensure stability during use, the rowing machine is equipped with two flywheels 26 in this embodiment, one located outside the first fixing plate 11 and the other outside the second fixing plate 12. Two power generation structures 4 are also provided, one corresponding to each of the two flywheels 26. This ensures that the rowing machine's motion structure is substantially symmetrical, ensuring overall stability during use.

[0032] Regarding the support structure of the bracket 1, in this embodiment, the bracket 1 further comprises a first bracket 13, a second bracket 14, a third bracket 15, and a fourth bracket 16. The first bracket 13 and the second bracket 14 are fixed at their ends, forming a V-shape as a whole, forming a first obtuse angle. The third bracket 15 and the fourth bracket 16 are fixed at their ends, forming a V-shape as a whole, forming a second obtuse angle. The first and second obtuse angles have the same opening direction. The first bracket 13 and the third bracket 15 are fixed at their ends, forming a V-shape as a whole, and the second bracket 14 and the fourth bracket 16 are fixed at their ends, forming a V-shape as a whole. The first fixing plate 11 and the second fixing plate 12 are fixed within the openings of the second bracket 14 and the fourth bracket 16. Support feet are provided at the ends of the first bracket 13 to form an overall support structure. At the same time, the first obtuse angle formed by the first bracket 13 and the second bracket 14, and the second obtuse angle formed by the third bracket 15 and the fourth bracket 16, and the first fixing plate 11 and the second fixing plate 12 are fixed between the inner side of the first obtuse angle and the outer side of the second obtuse angle, thereby forming a triangular support structure. This provides a more stable overall structure for the rowing machine.

[0033] During use of the rowing machine, the user needs to sit and slide. Therefore, in this embodiment, a track piece 5 is provided on the upper side of the third bracket 15. The track piece 5 is wider than the third bracket 15. A seat 6 is provided on the upper side of the track piece 5. A seat fixing piece 61 is provided on the lower side of the seat 6. The seat fixing piece 61 includes a left fixing piece 611 and a right fixing piece 612 on both sides of the third bracket 15. A roller 7 rotates between the left fixing piece 611 and the right fixing piece 612, and the roller 7 rolls on the upper side of the track piece 5. The seat 6 slides on the track piece 5 on the upper side of the third bracket 15 via the roller 7, thereby facilitating the user's use.

[0034] During the movement of the seat 6 and the rolling of the roller 7, in order to keep the seat 6 moving along the direction of the third bracket 15, in this embodiment, a limiting sleeve 71 is provided at the end of the roller 7. The limiting sleeve 71 is provided with a limiting step 711. The limiting step 711 is engaged with the outer side of the track piece 5 to limit the sliding of the roller 7 along the track piece 5. At this time, the limiting steps 711 at both ends of the roller 7 are engaged with the outer side of the track piece 5, so that the roller 7 is engaged with the upper side of the track piece 5. During the rotation of the roller 7, under the action of the limiting steps 711, the roller 7 moves along the direction of the third bracket 15.

[0035] During the movement of the seat 6, in order to prevent the seat 6 from detaching from the third bracket 15, in this embodiment, a limiting shaft 613 is provided on the lower side of the left fixing plate 611 and the right fixing plate 612, and the limiting shaft 613 is clamped at the lower side of the track plate 5. The third bracket 15 is also provided with a first limiting pad and a second limiting pad, which are respectively located at both ends of the third bracket 15. The end of the limiting shaft 613 is clamped in the lower side position of the track piece 5, which can prevent the seat 6 from being separated from the third bracket 15. Furthermore, a small roller 7 is rotatably set at the end of the limiting shaft 613. At this time, the small roller 7 is connected to the lower side of the track piece 5 (the track piece 5 protrudes from the side of the third bracket 15), which can ensure that the seat 6 is not easily flipped or fallen off when the track piece 5 moves to the upper side of the third bracket 15. At the same time, a first limiting pad and a second limiting pad are set at the end of the third bracket 15. The first limiting pad and the second limiting pad are elastic pads, which can be used to limit the moving position of the seat 6 and prevent the seat 6 from sliding out from the two ends of the third bracket 15. At the same time, when the seat 6 hits the first limiting pad and the second limiting pad, loud noise can be avoided and a certain buffer can be formed.

[0036] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
