DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] The core of the utility model is to provide a multifunctional rowing machine, which can perform not only rowing action training but also oar paddling action training, is easy to use and does not require the purchase of a rowing machine and an oar paddling machine separately.

[0034] It should be noted that the directions or positional relationships indicated by “upper”, “lower”, “front”, “back”, etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present application.

[0035] The present application provides a multifunctional rowing machine, comprising: a guide rail 4, a seat cushion 7, a frame 1, a rowing handle 2 and a paddle handle 3;

[0036] The guide rail 4 is a strip-shaped member, and a support seat is provided at one end of the guide rail 4;

[0037] The seat cushion 7 is slidably disposed above the guide rail 4, and the seat cushion 7 can be disposed at any position in the extending direction of the guide rail 4;

[0038] The rack 1 is connected to the guide rail 4. A support assembly is provided on the side of the rack 1 away from the guide rail 4. The guide rail 4 and the rack 1 can be kept in an empty state through the support seat and the support assembly.

[0039] The rowing handle 2 is connected to the resistance mechanism 6 through the first transmission mechanism. The resistance mechanism 6 is arranged on the frame 1. When the rowing handle 2 is pulled, the resistance mechanism 6 can be driven to rotate.

[0040] The two ends of the rowing handle 3 are respectively connected to a left paddle rope 12 and a right paddle rope 13, which are connected to the resistance mechanism 6 through a second transmission mechanism. Pulling the left paddle rope 12 or the right paddle rope 13 can drive the resistance mechanism 6 to rotate.

[0041] For details, please refer to the attached Figure 1 With attached Figure 2 The guide rail 4 is fixedly connected to the frame 1, and a certain distance is maintained between the support seat and the support assembly and the ground. The user can sit directly on the cushion 7, and the position of the cushion 7 can be adaptively adjusted by the user. The user pulls the rowing handle 2 in the direction away from the frame 1. The rowing handle 2 is connected to the resistance mechanism 6 through the first transmission mechanism. When the rowing handle 2 is pulled, a certain resistance will be encountered, and pulling the rowing handle 2 can drive the resistance mechanism 6 to rotate to achieve rowing action training. When the rowing handle 3 is pulled, the resistance mechanism 6 can also be driven to rotate by driving one or more of the left paddle rope 12 and the right paddle rope 13. In this process, a certain resistance will also be encountered to achieve rowing action training. It is very convenient to use and there is no need to purchase a rowing machine and a rowing machine separately, which can reduce costs and save space.

[0042] On the basis of the above embodiment, the resistance mechanism 6 includes a fan and a fan shaft 23, and the rowing handle 2 and the paddle handle 3 transmit torque to the fan shaft 23 through the first transmission mechanism and the second transmission mechanism respectively, so that the fan shaft 23 drives the fan to rotate.

[0043] Specifically, taking the cost into consideration, a fan is generally selected as the resistance mechanism 6. The fan blades are all arranged on the fan shaft 23. By rotating the fan shaft 23, the fan blades can be driven to rotate on a fixed axis. The rowing handle 2 and the paddle handle 3 are respectively connected to the fan shaft 23 through the first transmission mechanism and the second transmission mechanism and transmit torque to the fan shaft 23, so that there can be a certain resistance during rowing and paddle training.

[0044] Optionally, the resistance mechanism 6 can also use a magnetic resistance system or a combination of a magnetic resistance system and a wind resistance system, and can be selectively set according to customer needs.

[0045] On the basis of the above embodiment, the first transmission mechanism includes the second one-way bearing 24 , and the second transmission mechanism includes the first one-way bearing 21 .

[0046] Specifically, the arrangement of the first one-way bearing 21 and the second one-way bearing 24 can ensure that during the process of rowing or paddling, when the rowing handle 2 or the paddling handle 3 is pulled, the resistance mechanism 6 can be driven to rotate in one direction, and no reverse power will be generated during the rotation of the resistance mechanism 6, and the rowing motion and the paddling motion can be made not to interfere with each other. That is, during the paddling process, due to the arrangement of the second one-way bearing 24, the fan shaft 23 will not be driven, so the rowing handle 2 and related transmission structure related to the rowing action will not be affected or interfered. During the rowing process, due to the arrangement of the first one-way bearing 21, part of the structure of the second transmission mechanism will not be driven, that is, the left paddle rope wheel 18 and the right paddle rope wheel 17 connected to the main shaft 27 below will not be driven, so the left paddle rope 12 and the right paddle rope 13 related to the paddling action will not be affected or interfered.

[0047] On the basis of the above embodiment, the first transmission mechanism also includes a first connecting member 26, a first rotating wheel 25 and a first reset mechanism. One end of the first connecting member 26 is connected to the rowing handle 2, and the other end of the first connecting member 26 bypasses the first rotating wheel 25 and is connected to the first reset mechanism. The first connecting member 26 can drive the first rotating wheel 25 to rotate. The first rotating wheel 25 is fixed to the fan shaft 23. The second one-way bearing 24 is arranged at the end of the fan shaft 23 away from the first rotating wheel 25 and is used to drive the fan shaft 23 to rotate in one direction.

[0048] For details, please refer to the attached Figure 3 The first connecting member 26 is preferably a chain, and the first rotating wheel 25 is preferably a sprocket. The first connecting member 26 is wound around the first rotating wheel 25, and the first connecting member 26 can drive the first rotating wheel 25 to rotate. The first rotating wheel 25 is fixed to the fan shaft 23, so when the first rotating wheel 25 rotates, it drives the fan shaft 23 to rotate. The entire rowing process is: the user sits on the cushion 7, pulls the rowing handle 2 to drive the first connecting member 26 to do the rowing action, and the first connecting member 26 drives the first rotating wheel 25 to rotate. Because the first rotating wheel 25 is fixed on the fan shaft 23, the fan shaft 23 will drive the fan to rotate in one direction through the second one-way bearing 24, generating wind resistance. After completing a rowing action, the first reset mechanism drives the rowing handle 2 to reset, so as to facilitate the next rowing action. Due to the setting of the second one-way bearing 24, it can prevent the fan shaft 23 from transmitting reverse torque during the reset process.

[0049] Optionally, the first reset mechanism may be a spring or an elastic rope.

[0050] Based on the above embodiment, the first reset mechanism includes a sliding member 8 and an elastic member 9. The sliding member 8 is connected between the first connecting member 26 and the elastic member 9. The elastic member 9 is arranged on the frame 1. The elastic member 9 is retractable and is used to pull the sliding member 8 and the first connecting member 26 in a stretched state.

[0051] For details, please refer to the attached Figure 2 In the process of pulling the first connecting member 26, the first connecting member 26 will drive the sliding member 8 to move in the direction away from the user and tighten the elastic member 9. When the user stops exerting force, the elastic member 9 will drive the first connecting member 26 and the rowing handle 2 to move in the direction of the frame 1 to complete the return action. Due to the action of the second one-way bearing 24, the fan will not stop rotating or rotate in the opposite direction during the process of the first connecting member 26 and the rowing handle 2 moving in the direction of the frame 1.

[0052] Optionally, the elastic member 9 may be a rope with a certain elasticity, so that the elastic member 9 can be installed on the frame 1 and connected to the sliding member 8 .

[0053] Optionally, the sliding member 8 may be a movable pulley, which may increase the pulling stroke of the rowing handle 2 .

[0054] In some embodiments, the second transmission mechanism also includes a main shaft 27, a right paddle pulley 17, a left paddle pulley 18, a resistance adjustment mechanism and a second reset mechanism. The resistance adjustment mechanism is arranged on the main shaft 27 on the resistance mechanism 6, and the second reset mechanism is arranged on the main shaft 27 on the frame 1. The resistance adjustment mechanism is used to match the resistance required for rowing and paddling. The right paddle rope 13 is wound around the right paddle pulley 17 and can drive the right paddle pulley 17 to rotate. The left paddle rope 12 is wound around the left paddle pulley 18 and can drive the left paddle pulley 18 to rotate. The left paddle pulley 18 and the right paddle pulley 17 are both arranged on the first one-way bearing 21.

[0055] Specifically, the resistance required for rowing and paddling is different. Usually, the resistance required for rowing is large, and the resistance required for paddling is small. When rowing and paddling share a set of resistance mechanism 6, the resistance adjustment mechanism can reduce the resistance generated by the resistance mechanism and transmitted to the paddling handle 3 to meet the resistance requirement of paddling. The resistance required for rowing is the same as the resistance generated by the resistance mechanism 6. The first one-way bearing 21 is set on the main shaft 27 to drive the main shaft 27 to rotate in one direction to avoid generating reverse torque on the main shaft 27 when the paddling handle 3 is reset after each paddling action.

[0056] Based on the above embodiment, the resistance adjustment mechanism includes a first pulley 14, a transmission belt 15 and a second pulley 16. The first one-way bearing 21 is connected to the right paddle pulley 17. The first pulley 14 is provided on the main shaft 27. The first pulley 14 is connected to the second pulley 16 through the transmission belt 15, and the second pulley 16 is connected to the resistance mechanism 6.

[0057] It can be understood that the diameter of the first pulley 14 is greater than the diameter of the second pulley 16, so that the transmission ratio of the resistance adjustment mechanism can be adjusted to reduce the resistance transmitted to the paddling motion part.

[0058] For details, please refer to the attached Figure 4 , Attachment Figure 5 With attached Figure 6 The right paddle pulley 17 is arranged below the frame 1 and is connected to the right paddle pulley 17 with a first one-way bearing 21. The first one-way bearing 21 is arranged on the main shaft 27. The main shaft 27 is provided with a first pulley 14. The first pulley 14 is connected to the second pulley 16 through a transmission belt 15. The user sits on the seat cushion 7 and pulls the rowing handle 3 to drive the left paddle rope 12 and the right paddle rope 13 to perform rowing movements. The right paddle rope 13 is wound around the right paddle pulley 17 in advance. When the user pulls the right paddle rope 13, the right paddle pulley 17 rotates and drives the main shaft 27 to rotate through the first one-way bearing 21 fixed on the right paddle pulley 17. The main shaft 27 will drive the first pulley 14 to rotate and then drive the second pulley 16 to rotate through the transmission belt 15. The second pulley 16 is installed on the fan, so it will drive the fan to rotate and generate wind resistance. A needle bearing 22 is also provided in the second pulley 16 for supporting the second pulley 16. During the rowing process, due to the provision of the second one-way bearing 24, the fan shaft 23 will not be driven, so the transmission structure related to the rowing action will not be affected or interfered.

[0059] Optionally, both the first pulley 14 and the second pulley 16 may be belt pulleys, which are low in cost and easy to maintain and replace.

[0060] On the basis of the above embodiment, a left paddle elastic rope wheel 28 and a right paddle elastic rope wheel 29 are also provided on the main shaft 27, the left paddle elastic rope wheel 28 is connected to the left paddle rope wheel 18 and rotates synchronously, the right paddle elastic rope wheel 29 is connected to the right paddle rope wheel 17 and rotates synchronously, the second reset mechanism includes a left paddle elastic rope 20 and a right paddle elastic rope 19, one end of the left paddle elastic rope 20 and the right paddle elastic rope 19 are both connected to the frame 1, the other end of the left paddle elastic rope 20 is wound around the left paddle elastic rope wheel 28, and the other end of the right paddle elastic rope 19 is wound around the right paddle elastic rope wheel 29.

[0061] Specifically, the main shaft 27 is also provided with a left paddle elastic rope wheel 28 and a right paddle elastic rope wheel 29. The left paddle elastic rope wheel 28 and the left paddle rope wheel 18 rotate synchronously, and the right paddle elastic rope wheel 29 rotates synchronously with the right paddle rope wheel 17. The left paddle elastic rope 20 and the right paddle elastic rope 19 are both arranged below the frame 1, and one end of both is connected to the frame 1. Taking the left paddle elastic rope 20 as an example, the other end of the left paddle elastic rope 20 is wound around the left paddle elastic rope wheel 28. When the user pulls the left side of the rowing handle 3, the left paddle rope 12 can drive the left paddle rope wheel 18 to rotate, and the left paddle elastic rope wheel 28 also rotates synchronously, and the left paddle elastic rope 20 is wound around the left paddle elastic rope wheel 28. When the user stops applying force, the left paddle elastic rope 20 pulls the left paddle elastic rope wheel 28 to rotate in the opposite direction, and the left paddle rope wheel 18 also rotates in the opposite direction synchronously, and the left paddle rope 12 is reset. During the resetting process of the paddling movement, the first one-way bearing 21 will not transmit a torque in the opposite direction of the current movement process to the main shaft 27 .

[0062] Optionally, the right paddle elastic rope 19 and the left paddle elastic rope 20 may be made of other elastic parts, such as springs, elastic ropes, etc., and may be adjusted and replaced according to the resistance required for training.

[0063] On the basis of the above embodiment, a left rotating seat 10 and a right rotating seat 11 are further provided on the frame 1, and the left rotating seat 10 and the right rotating seat 11 are both rotatable. The left paddle rope 12 is wound around the left rotating seat 10, and the right paddle rope 13 is wound around the right rotating seat 11.

[0064] Specifically, a left rotating seat 10 and a right rotating seat 11 are arranged on the frame 1, and a left paddle rope 12 and a right paddle rope 13 are wound around them respectively. The left rotating seat 10 and the right rotating seat 11 can rotate around a fixed axis to prevent additional friction or stress from being generated between the rotating seat and the rope, thereby reducing the burden on the user during paddling action training.

[0065] In some embodiments, an electronic meter 5 is provided on the frame 1 , and the electronic meter 5 is connected to a power supply device and a resistance mechanism 6 .

[0066] Specifically, the electronic meter 5 provided on the frame 1 is used to detect the rotation time, output power and other data of the fan and display them on the screen. After conversion according to relevant formulas, the user can intuitively understand the specific training time and training intensity. A music playing function can also be added to facilitate relaxation for the user.

[0067] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
