Technical Field

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

[0002] The indoor rowing machine is an innovative piece of fitness equipment inspired by canoeing competitions. It trains athletes in a sport similar to rowing, bringing the sport indoors. Recognizing the impact of weather and other factors on outdoor rowing, a more convenient device was developed, unrestricted by location or weather. When it was invented, it was embraced by rowers and fitness enthusiasts alike.

[0003] Current rowing machines use a lever to drive a sleeve assembly to rotate, thus achieving the rowing motion. The machine also contains a motor that provides auxiliary power and allows for adjustment of exercise intensity during training. When the lever is pulled, the motor rotates forward; on the return stroke, the motor rotates in reverse to pull the athlete back to the starting position. However, existing motors experience a lull during the transition from forward to reverse rotation, resulting in an uneven movement. Utility Model Content

[0016] An outer sleeve is disposed on one side of the force generating assembly and is connected to the rotor;

[0017] A locking element is provided, through which the outer sleeve is rotatably connected to the connecting shaft.

[0018] In one embodiment, the first elastic element is made of an elastic rope, with a first end connected to the outer sleeve and a second end connected to the frame.

When the pull rod is pulled along the first direction, the second elastic element deforms to generate a driving force to drive the sleeve assembly to wind the pull rope.

[0033] Compared to existing technologies, when the user pulls the lever outward in the first direction, the sleeve assembly rotates synchronously. At this time, the drive component within the force-generating assembly rotates forward, and the first elastic element deforms, generating a driving force that propels the sleeve assembly to wind the rope. When the user stops pulling the lever, the drive component switches from forward to reverse rotation. During the interval between the forward and reverse rotation, the first elastic element drives the sleeve assembly to wind the rope, thereby improving the stability of the rowing machine during operation.

[0050] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0051] Existing rowing machines have a technical problem where the motor experiences a lull during the transition from forward to reverse rotation, resulting in uneven movement.

[0052] Therefore, this application provides a rowing machine, characterized in that the rowing machine includes,

[0053] A rowing machine body, the rowing machine body including a force generating component, the force generating component being used to provide rowing resistance;

[0054] A sleeve assembly, wherein the sleeve assembly is drively connected to the force generating assembly;

[0055] A frame, the frame being arranged along a first direction, with the rowing machine body fixedly connected to one side of the frame;

[0056] A pull rod and a pull rope are provided. The pull rod is connected to the sleeve assembly via the pull rope. When the pull rod is pulled in the first direction, the force generating assembly and the sleeve assembly rotate synchronously.

[0057] A first elastic element is connected to the sleeve assembly. When the pull rod is pulled along the first direction, the first elastic element generates a driving force that drives the sleeve assembly to wind the pull rope.

[0058] Example 1:

[0059] Please refer to the attached document. Figure 1 To be continued Figure 3As shown, a specific embodiment of the rowing machine of this application is presented. The rowing machine of this application enables indoor rowing practice. When the user pulls the lever outward in a first direction, the sleeve assembly rotates synchronously. At this time, the driving component within the force generating component simultaneously rotates forward, and the first elastic element generates and forms a driving force to drive the sleeve assembly to wind the rope. When the user stops pulling the lever, the driving component switches from forward to reverse rotation. During the interval between the forward and reverse rotation, the first elastic element drives the sleeve assembly to wind the rope, thereby improving the stability of the rowing machine during exercise. In the prior art, the indoor rowing machine is an innovative fitness device inspired by canoeing competitions, exercising a sport similar to rowing. Its invention brought rowing from the outdoors to the indoors. Considering the influence of weather and other factors on outdoor rowing, a more convenient device for trainees was developed, unrestricted by any venue or weather conditions. When the machine was invented, it was favored by many rowers and fitness enthusiasts. Existing rowing machines include a rowing machine body, a pull rod, a pull rope, and a sleeve assembly. The drive unit, located within the rowing machine body, drives the force-generating component within the machine to rotate. The sleeve assembly is connected to the force-generating component via a transmission connection. The pull rod is connected to the sleeve assembly via the pull rope. The user pulls the pull rod to drive the sleeve assembly to rotate, thus achieving the rowing motion. The drive unit within the rowing machine can provide a certain amount of assistance based on settings during the user's rowing, helping them easily complete the rowing motion. It can also control changes in resistance to more accurately simulate different scenarios. However, existing drive units experience a lull during the transition from forward to reverse rotation; this lull refers to the period during which the drive unit does not rotate.

[0060] Please refer to the attached document. Figure 1 To be continued Figure 3 As shown, the first direction X of this application refers to the length direction of the rowing machine 10, that is, the direction from front to back or from back to front. In this application, the rowing machine body 100 is positioned forward relative to the seat 430, and the seat 430 is positioned backward relative to the rowing machine body 100. The second direction Y of this application refers to the width direction of the rowing machine 10, that is, the direction from left to right or from right to left. The third direction Z of this application refers to the height direction of the rowing machine 10, that is, the direction from top to bottom or from bottom to top. In this application, the rowing machine body 100 is positioned higher relative to the frame 300, and the frame 300 is positioned lower relative to the rowing machine body 100.

[0061] Appendix Figure 1 This is a schematic diagram of one possible structure of the rowing machine 10 of this application. Figure 2 This is another structural schematic diagram of the rowing machine 10 of this application. Please refer to the attached diagram. Figure 1 and appendix Figure 2As shown, the rowing machine 10 of this application includes a frame 300 and a base 310, with the frame 300 arranged along a first direction X. In this application, the frame 300 is a plate-like structure or a rod-like structure.

[0062] In one embodiment, the frame 300 is a long, rod-shaped structure.

[0063] In one embodiment, the frame 300 is an integrated structure.

[0064] In one embodiment, the frame 300 is a segmented structure, and the segmented frame 300 needs to be assembled before use. The segmented frame 300 is convenient for transportation and storage.

[0065] The frame 300 has bases 310 at both ends along the first direction X. The bases 310 are located at the bottom of the frame 300 and are fixedly connected to the frame 300 to achieve stable placement of the frame 300. Furthermore, the bases 310 are rod-shaped structures arranged along the second direction Y.

[0066] Furthermore, the frame 300 of this application is provided with a first fixed position 320, which is used to connect the second elastic member 900. The first fixed position 320 and the seat 430 are spaced apart on the frame 300 along the first direction X. The first fixed position 320 is located closer to the rowing machine body 100 relative to the seat 430.

[0067] Please refer to the attached document. Figure 1 and appendix Figure 2 As shown, the rowing machine 10 of this application also includes a rowing machine body 100, which is fixedly connected to one side of the frame 300. Furthermore, the rowing machine body 100 is positioned above the frame 300. The rowing machine body 100 includes a force generating assembly 110, which provides rowing resistance by rotation.

[0068] Please refer to the attached document. Figure 1 and appendix Figure 2 As shown, the rowing machine 10 of this application also includes a pull rod 410 and a pull rope 420. The pull rod 410 is connected to the force generating component 110 through the pull rope 420. When the pull rod 410 is pulled in the first direction X, the force generating component 110 rotates synchronously to realize the rowing motion.

[0069] In one embodiment, the pull rope 420 includes a winding section 421 and a straight pull section 422. The winding section 421 is wound around the force generating component 110 and rotates synchronously with the force generating component 110. The straight pull section 422 is straightened along a first direction X. The first end of the straight pull section 422 is connected to the pull rod 410, and the second end of the straight pull section 422 is connected to the winding section 421. The straight pull section 422 moves along the first direction X under the pull of the pull rod 410.

[0070] In one embodiment, the pull rod 410 is arranged along the second direction Y. The pull rod 410 includes a connecting section and a handle section. Both ends of the connecting section are provided with handle sections, and the connecting section is connected to the pull rope 420. The exerciser holds the handle sections with both hands and pulls along the first direction X to realize the rotation of the force generating component 110.

[0071] Please refer to the attached document. Figure 1 and appendix Figure 2 As shown, the rowing machine 10 of this application includes a guide assembly 800 and guide positions. Several guide positions are spaced along the third direction Z between the pull rod 410 and the force generating assembly 110. The distance between different guide positions and the frame 300 along the third direction Z is different, meaning different guide positions have different heights. The guide positions are used to arrange the guide assembly 800, which is rotatably connected to the pull rope 420. Furthermore, the pull rope 420 passes through the guide assemblies 800 at different positions to adjust the initial height of the pull rod 410 in the third direction Z. The initial height of the pull rod 410 in the third direction Z refers to the distance between the pull rod 410 and the frame 300 when the exerciser is not pulling the pull rod 410. When the initial height can be adjusted, exercisers of different heights can find a suitable initial height to ensure standardized exercise movements and further facilitate exercise for people of different heights.

[0072] In this application, the guide components 800 can be arranged such that guide components 800 are arranged at all guide positions. Alternatively, the guide components 800 can be detachably connected to the guide positions, that is, the guide components 800 are installed in the currently used guide positions, and the guide components 800 are not installed in the unused guide positions.

[0073] In one embodiment, the rowing machine 10 includes three guide positions. These three guide positions are merely one specific implementation of this application, and the application may also include other numbers of guide positions.

[0074] Please refer to the attached document. Figure 1 and appendix Figure 2 As shown, the rowing machine 10 of this application also includes a seat 430. The seat 430 is provided on the side of the guide assembly 800 away from the rowing machine body 100. The exerciser sits on the seat 430 and pulls the lever 410 with both hands to perform rowing exercises. Furthermore, the seat 430 is slidably connected to the frame 300 along the first direction X.

[0075] Please refer to the attached document. Figure 1 and appendix Figure 2As shown, the rowing machine 10 of this application also includes a pedal 440. The pedal 440 is mounted on the frame 300 between the seat 430 and the guide assembly 800, and the pedal 440 is connected to the frame 300. Furthermore, the frame 300 and the pedal 440 are either fixedly connected or rotatably connected. With the rotatable connection between the frame 300 and the pedal 440, the rotation angle of the pedal 440 is adjustable to accommodate different exercisers. When exercising, the user's feet rest against the pedal 440 for support.

[0076] In one embodiment, an angle is formed between the pedal 440 and the frame 300.

[0077] Please refer to the attached document. Figure 1 and appendix Figure 2 As shown, the rowing machine 10 of this application also includes a vertical rod, which is used to arrange guide positions. The vertical rod is disposed on one side of the rowing machine body 100 and is arranged along the third direction Z. Further, the vertical rod is disposed on the side of the rowing machine body 100 near the seat 430. The vertical rod is provided with a plurality of guide positions along the third direction Z, and adjacent guide positions are spaced apart.

[0078] In one embodiment, the vertical rod is a rod-like component.

[0079] Please refer to the attached document. Figure 1 and appendix Figure 2 As shown, the rowing machine 10 of this application also includes a first elastic element 500, which can be made of elastic rope. The first elastic element 500 includes a first end and a second end. The first end of the first elastic element 500 is connected to the outer sleeve 210 in the force generating assembly 110, and the second end of the first elastic element 500 is connected to the frame 300. The second end of the first elastic element 500 can also be connected to the bottom of the rowing machine body 100. When the user pulls the lever 410 in the first direction X, the outer sleeve 210 in the force generating assembly 110 rotates simultaneously and winds the first elastic element 500 around the outer sleeve 210. The first elastic element 500 simultaneously stretches and deforms to generate a driving force for the drive sleeve assembly 200 to wind the pull rope 420. When the exerciser cancels the pull on the lever 410, the driving force of the first elastic element 500 drives the sleeve assembly 200 to wind the pull rope 420, and pulls the exerciser and the seat 430 towards the rowing machine body 100 at the same time, so as to reduce the impact of the drive component being in neutral when switching the rotation direction, making the entire movement process of the rowing machine 10 smoother.

[0080] Please refer to the attached document. Figure 1 and appendix Figure 2As shown, the rowing machine 10 of this application also includes a second elastic element 900, which is also made of elastic rope. The second elastic element 900 is arranged along a first direction X. The first end of the second elastic element 900 along the first direction X is connected to the seat 430, and the second end of the second elastic element 900 along the first direction X is also connected to the seat 430. When the lever 410 is pulled along the first direction X, the seat 430 moves away from the rowing machine body 100 at the same time, and the second elastic element 900 is simultaneously stretched and deformed, forming a driving force that drives the seat 430 to move toward the rowing machine body 100. When the user releases the pull on the lever 410, the driving force of the second elastic element 900 further pulls the seat, allowing the user to return to the initial position more quickly.

[0081] In this application, the rowing machine 10 can be used with or without electricity. When used without electricity, if the power is supplied only by the energy storage system inside the rowing machine 10, it will put a lot of pressure on the energy storage system and further reduce the life of the energy storage system. The first elastic element 500 and the second elastic element 900 can further reduce the pressure on the energy storage system.

[0082] Appendix Figure 3 This is a structural schematic diagram of the rowing machine body 100 of this application. Please refer to the attached diagram. Figure 3 As shown, the force generating assembly 110 of this application includes a rotor 111 and a stator 112. The stator 112 is located inside the rotor 111 and is rotatably connected to the rotor 111. A magnet is further provided on the rotor 111, and a copper wire is provided on the stator 112. The resistance to relative rotation between the rotor 111 and the stator 112 is adjusted by controlling the current flowing through the copper wire. The force generating assembly 110 of this application also includes a connecting shaft 113, which passes through the stator 112 along a second direction Y and is fixedly connected to the stator 112. The connecting shaft 113 extends along the second direction Y to the outside of the rotor 111, with the portion extending beyond the rotor 111 positioned near the sleeve assembly 200. The force generating assembly 110 of this application also includes a driving member for driving the rotor 111 to rotate around the stator 112. Furthermore, a through hole is provided radially through the connecting shaft 113, and the through hole is connected to the first intermediate member 600 through the first connecting member 610.

[0083] Please refer to the attached document. Figure 3As shown, the force generating component 110 is connected to the pull rope 420 via the sleeve assembly 200. The sleeve assembly 200 includes an outer sleeve 210, which is a hollow structure. The outer sleeve 210 has several diameters, and the output resistance value of the force generating component 110 can be adjusted by replacing the outer sleeve 210 with different diameters. The sleeve assembly 200 also includes a connecting post, which is disposed on the outer sleeve 210 and connected to the rotor 111 via the connecting post. The sleeve assembly 200 also includes a locking element 220, through which the outer sleeve is connected to the connecting shaft 113.

[0084] Please refer to the attached document. Figure 3 As shown, the first elastic element 500 of this application can also be made of a coil spring. A first receiving space 510 is formed inside the coil spring along the second direction Y. The connecting shaft 113 is located inside the first receiving space 510. The first elastic element 500 includes a first end and a second end from the inside to the outside. The first end of the first elastic element 500 is connected to the connecting shaft 113, and the second end of the first elastic element 500 is connected to the outer sleeve 210. When the user pulls the lever 410 along the first direction X, the outer sleeve 210 in the force generating assembly 110 rotates simultaneously, and the first elastic element 500 undergoes a winding deformation to generate a driving force for the drive sleeve assembly 200 to wind the pull rope 420. When the user cancels the pull on the lever 410, the driving force of the first elastic element 500 drives the sleeve to wind the pull rope 420, and pulls the user and the seat 430 simultaneously toward the rowing machine body 100, so as to reduce the impact of the drive component being in a neutral position when switching rotation directions, making the entire movement of the rowing machine 10 smoother.

[0085] Please refer to the attached document. Figure 3 As shown, the rowing machine 10 of this application also includes a first intermediate component 600, which is a sleeve-shaped structure. The first intermediate component 600 is provided to further provide a limiting groove 620. Because other components need to be connected to the connecting shaft 113 for different exercise modes, the limiting groove 620 cannot be directly provided on the connecting shaft 113. The first intermediate component 600 has a second cavity through it along the first direction X. The first intermediate component 600 is sleeved on the outside of the connecting shaft 113 and is fixed to the connecting shaft 113 by the first connector 610. A limiting groove 620 is formed on the first intermediate component 600 along the second direction Y. The limiting groove 620 communicates with the second cavity. An opening is provided on the side of the limiting groove 620 near the outer sleeve 210.

[0086] In one embodiment, the first connector 610 is a fixing pin or a fixing bolt.

[0087] Please refer to the attached document. Figure 3As shown, the rowing machine 10 of this application also includes a second intermediate component 700, which is a sleeve-shaped structure. The second intermediate component 700 is provided to further limit and fix the first intermediate component 600 and the first elastic component 500. The second intermediate component 700 has a third cavity extending through it along the second direction Y. The second intermediate component 700 is sleeved outside the first intermediate component 600. The second intermediate component 700 has a first connecting position and a second connecting position, and both the second connecting position and the second connecting position have connecting holes. The rowing machine 10 of this application also includes a second connecting component 710 and a limiting component. The first end of the first elastic component 500 is fixedly connected to the first connecting position through the second connecting component 710. The first limiting component 720 passes through the second connecting component 710 and extends into the limiting groove 620 to form a circumferential limiting of the second intermediate component 700. Furthermore, multiple first limiting components 720 are provided along the second direction Y. In this application, the locking member 220 is connected to the connecting shaft 113 to restrict the second intermediate member 700 between the rotor 111 and the locking member 220, and to form an axial limit for the second intermediate member 700.

[0088] In one embodiment, the second connector 710 and the first limiting member 720 are fixing pins or fixing bolts.
