Description

Technical Field

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

[0002] A rowing machine is a machine used for training to simulate the sport of water rowing. Indoor rowing competitions have become a professional sport. Indoor rowing machines are also commonly known as ergometers, which measure the power consumed by the exerciser during exercise.

[0003] A Chinese patent application document with the publication number CN116474313A discloses a rowing machine, which includes a horizontally placed bracket and water tanks located at one end of the bracket and distributed on both sides of the bracket. When the bracket is in a horizontally placed state, the water tanks are mounted above the bracket. The water tank includes an inner cover fixed to the side of the bracket and an outer cover hermetically covering the outside of the inner cover. The outer cover is recessed away from the inner cover to form a water storage cavity. A screw rod assembly is provided above the bracket. Both ends of the screw rod assembly are respectively rotatably passed through the inner covers on both sides, and the part of the screw rod assembly passing through the inner cover is connected with a paddle. The paddle cooperates with the liquid in the water storage cavity to simulate the damping of rowing motion. A retractable scroll spring box, a driving belt pulley, a driven belt pulley, a transmission belt and a magnetic control flywheel are also provided above the bracket and between the two water tanks. The screw rod assembly is arranged on the driven belt pulley. The retractable scroll spring box is pulled by an external webbing, and a handle for facilitating people to pull the webbing is also provided on the webbing.

[0004] When people need to use the above rowing machine for exercise, they can pull the handle, so that the webbing on the handle drives the retractable scroll spring box to rotate. At this time, the retractable scroll spring box will drive the driving belt pulley to rotate, and the driving belt pulley will drive the electromagnetic flywheel and the driven belt pulley to rotate through the transmission belt. The rotation of the electromagnetic flywheel will transmit damping to the pulling of the webbing. At the same time, because the driven belt pulley is arranged on the screw rod assembly, when the driven belt pulley rotates, the paddles arranged at both ends of the screw rod assembly will rotate in the water storage cavity, thereby transmitting damping to the pulling of the webbing, so as to achieve the exercise effect. An electronic watch for displaying exercise details is usually provided on the rowing machine. Using the electronic watch requires an additional connection to a power source equipped with a battery, and the battery has limited power and needs to be replaced frequently, thus increasing the cost required for long-term use of the rowing machine. Summary of the Utility Model

[0005] Aiming at the shortcomings of the prior art that an electronic watch for displaying exercise details is usually provided on a rowing machine, and using the electronic watch requires an additional connection to a power source equipped with a battery, and the battery has limited power and needs to be replaced frequently, thus increasing the cost required for long-term use of the rowing machine, the utility model provides a rowing machine with a self-power generation structure.

[0006] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0007] A rowing machine includes a rowing machine body and an electronic watch provided on the rowing machine body. The rowing machine body includes an exercise component and a first driven pulley driven by the exercise component. A self-power generation structure for powering the electronic watch when people use the exercise component to exercise is provided inside the rowing machine body. The self-power generation structure includes a generator electrically connected to the electronic watch, and the generator is driven by the first driven pulley to generate electricity.

[0008] With the above solution, when people use the exercise component on the rowing machine body to exercise, the exercise component will drive the first driven pulley to rotate. When the first driven pulley rotates, it can drive the generator to generate electricity. Since the generator is electrically connected to the electronic watch, when people use the exercise component to exercise, it can power the electronic watch, thereby reducing the cost required for long-term use of the rowing machine.

[0009] Preferably, the first driven pulley is provided on the input shaft of the generator.

[0010] With the above solution, directly setting the first driven pulley on the input shaft of the generator enables the first driven pulley to directly drive the input shaft of the generator to rotate, thereby generating electricity for the electronic watch.

[0011] Preferably, at least one set of pulley assemblies for driving the input shaft of the generator to rotate is further provided between the first driven pulley and the input shaft of the generator.

[0012] Preferably, the pulley assembly includes a second driving pulley connected to the first driven pulley through a rotating shaft and rotating simultaneously, a second driven pulley provided on the input shaft of the generator, and a second transmission belt for driving the second driven pulley to rotate following the second driving pulley. The diameter of the second driving pulley is larger than that of the first driven pulley.

[0013] With the above solution, the provided second driving pulley can rotate together when the first driven pulley rotates. When the second driving pulley rotates, the second driven pulley provided on the input shaft of the generator will rotate following the second driving pulley through the second transmission belt. Since the diameter of the second driving pulley is larger than that of the second driven pulley, the input shaft of the generator will accelerate under the belt of the second driven pulley, thereby improving the power generation efficiency of the generator.

[0014] Preferably, a power storage component electrically connected to the generator and capable of storing the electricity generated by the generator is further provided on the bracket.

[0015] Preferably, the power storage component includes an electronic control board electrically connected to the generator. A storage battery for storing electricity is electrically connected to the electronic control board, and the storage battery is electrically connected to the electronic watch.

[0016] With the above solution, the electric control board can be used to control the charging and discharging of the storage battery thereon, and the storage battery arranged on the electric control board can store the electricity generated by the generator. At the same time, since the storage battery is electrically connected to the electronic watch, the storage battery can also provide power for the electronic watch, so that the electronic watch can display the exercise parameters of a person when using the rowing machine.

[0017] Since the utility model adopts the above technical solution, it has remarkable technical effects: when people exercise with the exercise component on the rowing machine body, the exercise component will drive the first driven pulley to rotate, and when the first driven pulley rotates, it can drive the generator to generate electricity. Since the generator is electrically connected to the electronic watch, when people exercise with the exercise component, it can supply power to the electronic watch, thereby reducing the cost required for long-term use of the rowing machine.

The rowing machine body includes an exercise component and a first driven pulley 701 driven by the exercise component. The exercise component includes a webbing 3, a rewinding scroll spring box 5 for winding the webbing 3, a first driving pulley 601 provided on one side of the rewinding scroll spring box 5 and rotating together with the rewinding scroll spring box 5, and an electromagnetic flywheel 13 for providing damping for the pulling of the webbing 3. The first driving pulley 601 drives the first driven pulley 701 to rotate together through a first transmission belt 801. A handle 4 for facilitating the user to pull the webbing 3 is provided at one end of the webbing 3 away from the rewinding scroll spring box 5. A self-power generation structure for powering the electronic watch 1 when people use the exercise component to exercise is provided inside the rowing machine body. The self-power generation structure includes a generator 9 electrically connected to the electronic watch 1. The generator 9 in this embodiment is a permanent magnet direct current brushless generator, and the generator 9 is driven by the first driven pulley 701 to generate electricity.

[0026] Reference Figures 2 - 3 , the first driven pulley 701 is provided on the input shaft 14 of the generator 9, or at least one set of pulley components for driving the input shaft 14 of the generator 9 to rotate is further provided between the first driven pulley 701 and the input shaft 14 of the generator 9. In this embodiment, one set of pulley components is provided between the first driven pulley 701 and the generator 9. The pulley components include a second driving pulley 602 connected to the first driven pulley 701 through a rotating shaft 10 and rotating simultaneously, a second driven pulley 702 provided on the input shaft 14 of the generator 9, and a second transmission belt 802 for driving the second driven pulley 702 to follow the second driving pulley 602 to rotate. The diameter of the second driving pulley 602 is larger than the diameter of the first driven pulley 701.

[0027] Reference Figure 1 , Figure 4 , a power storage component electrically connected to the generator 9 and capable of storing the electricity generated by the generator 9 is further provided on the bracket 2. The power storage component includes an electronic control board 11 electrically connected to the generator 9. A storage battery 12 for storing electricity is electrically connected to the electronic control board 11, and the storage battery 12 is electrically connected to the electronic watch 1.

[0028] In this embodiment, the diameter D1 of the first driving pulley 601 = 136, the diameter D2 of the first driven pulley 701 = 70, the diameter D3 of the second driving pulley 602 = 76, and the diameter D4 of the second driven pulley 702 = 15. Therefore, the transmission ratio That is, when the first driving pulley 601 rotates one circle, the second driven pulley 702 rotates about 10 circles.

[0029] Specific power generation process: When the user pulls the webbing 3 through the handle 4, the webbing 3 will drive the rewinding volute spring box 5 to rotate. When the rewinding volute spring box 5 rotates, it will drive the first driving pulley 601 to rotate together. Since the first driving pulley 601 is connected to the first driven pulley 701 through the first transmission belt 801, the first driven pulley 701 will follow the first driving pulley 601 to rotate. Since the first driven pulley 701 is connected to the second driving pulley 602 through rotation, when the first driven pulley 701 rotates, the second driving pulley 602 will rotate together. When the second driving pulley 602 rotates, it will drive the second driven pulley 702 to rotate through the second transmission belt 802. Since the second driven pulley 702 is arranged on the input shaft 14 of the generator 9, the second driven pulley 702 will drive the generator 9 to generate electricity. Since the generator 9 is electrically connected to the electronic control board 11, the electricity generated by the generator 9 will be transmitted to the storage battery 12 on the electronic control board 11. And the storage battery 12 is electrically connected to the electronic watch 1, so the storage battery 12 will output the electricity to the electronic watch 1 to supply power to the electronic watch 1, thereby reducing the cost required for long-term use of the rowing machine.
