[0002] Magnetic resistance is a common resistance generation mechanism in modern fitness equipment, especially in aerobic fitness equipment such as indoor bicycles, elliptical machines and rowing machines. The working principle of magnetic resistance system is to adjust the resistance by changing the distance between the magnet and the metal flywheel. Magnetic resistance includes magnets and flywheels. Magnets usually use permanent magnets. These magnets can be fixed in position or movable to change their distance from the flywheel. The flywheel is a heavy metal disk used to simulate inertia in real sports. The magnets attract the flywheel, increasing the resistance to the flywheel's rotation. The user drives the flywheel to rotate to achieve the user's exercise.

[0003] During use, the magnetic resistance structure inside the existing fitness equipment is not convenient to combine with elastic ropes to increase the pullback force of the magnetic resistance structure, which affects the fitness equipment's simulation of real sports experience and reduces the user's training efficiency and muscle growth. Utility Model Content

[0004] The purpose of the utility model is to provide a structure combining magnetic resistance and elastic force inside fitness equipment, which has the advantage of good training effect and solves the problem that the magnetic resistance structure inside the existing fitness equipment is not convenient to combine with elastic ropes to increase the pullback force of the magnetic resistance structure during use, which affects the fitness equipment's simulation of real sports experience and reduces the user's training efficiency and muscle growth.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a structure combining magnetic resistance and elastic force inside a fitness equipment, including a magnetic resistance mechanism:

[0006] The magnetic resistance mechanism comprises a drawstring, a lifting member is fixedly installed on the left end of the drawstring, and an elastic rope is fixedly connected to the bottom of the lifting member;

[0007] The bottom of the drawstring is movably connected to a first guide wheel, and the surface of the elastic rope is movably connected to a second guide wheel and a third guide wheel respectively. The first guide wheel guides the drawstring, and the second guide wheel and the third guide wheel guide the elastic rope. The first guide wheel is rotatably connected to a first connecting seat, the second guide wheel is rotatably connected to a second connecting seat, and the third guide wheel is rotatably connected to a third connecting seat.

[0008] As a preferred structure combining magnetic resistance and elastic force inside a fitness equipment of the utility model, the magnetic resistance mechanism also includes two mounting plates, and a magnetic wheel and a flywheel are respectively installed on opposite sides of the two mounting plates, and the right end of the pull belt passes through the first connecting seat and is fixedly connected to the surface of the flywheel.

[0009] As a preferred structure combining magnetic resistance and elastic force inside a fitness equipment of the utility model, the magnetic wheel is fixedly connected to the mounting plate, and the flywheel is rotatably connected to the mounting plate.

[0010] As a preferred structure combining magnetic resistance and elastic force inside a fitness equipment of the utility model, a pull rope is fixedly connected to the top of the lifting member.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model can realize different types of resistance training through the combination of magnetic resistance and elastic rope, providing users with more training options. The magnetic resistance provides stable resistance, while the elastic rope provides dynamic elastic resistance during the pullback process. The two work together to increase the difficulty of training, thereby improving the training effect. In addition, the elastic rope can provide a buffering effect, reduce the impact on the joints during sudden stops or accelerations, and help reduce the risk of injury.

[0015] 2. The utility model uses the stability of the magnetic resistance mechanism and the elastic recovery of the elastic rope to ensure that even if the user suddenly stops during training, the device can safely return to the initial position, reducing the possibility of accidents. The design of the composite resistance makes the training process more interesting, which can attract users to persist in training and improve their enthusiasm for training.

DETAILED DESCRIPTION

[0019] See also Figure 1-Figure 2 , a structure combining magnetic resistance and elastic force inside a fitness equipment, including a magnetic resistance mechanism 1.

[0020] Furthermore, the magnetic resistance mechanism 1 includes a pull belt 104 , a lifting member 3 is fixedly installed on the left end of the pull belt 104 , and an elastic rope 8 is fixedly connected to the bottom of the lifting member 3 .

[0021] Furthermore, a first guide wheel 5 is movably connected to the bottom of the drawstring 104, and a second guide wheel 9 and a third guide wheel 6 are movably connected to the surface of the elastic rope 8 respectively. The first guide wheel 5 guides the drawstring 104, and the second guide wheel 9 and the third guide wheel 6 guide the elastic rope 8. The first guide wheel 5 is rotatably connected to the first connecting seat 2, the second guide wheel 9 is rotatably connected to the second connecting seat 10, and the third guide wheel 6 is rotatably connected to the third connecting seat 7.

[0022] Furthermore, the magnetic resistance mechanism 1 also includes two mounting plates 101 , and a magnetic wheel 102 and a flywheel 103 are respectively mounted on opposite sides of the two mounting plates 101 . The right end of the pull belt 104 passes through the first connecting seat 2 and is fixedly connected to the surface of the flywheel 103 .

[0023] Furthermore, the magnetic wheel 102 is fixedly connected to the mounting plate 101 , and the flywheel 103 is rotationally connected to the mounting plate 101 .

[0024] Furthermore, a pull rope 4 is fixedly connected to the top of the lifting member 3 .

[0025] Furthermore, there are several elastic ropes 8 , which are located at the front and rear sides of the magnetic resistance mechanism 1 .

[0026] Furthermore, the first guide wheel 5 is located on the left side of the magnetic resistance mechanism 1, the second guide wheel 9 is located on the left and right sides of the bottom of the magnetic resistance mechanism 1, and the third guide wheel 6 is located on the right side of the magnetic resistance mechanism 1. The elastic rope 8 first passes through the left side of the first guide wheel 5, and then passes through the bottom of the second guide wheel 9 and the right side of the third guide wheel 6 in turn.

[0027] During use, the user pulls the pull rope 4 to make the lifting member 3 rise. At this time, the pull belt 104 fixed to the bottom of the lifting member 3 will also move accordingly. The first guide wheel 5 guides the pull belt 104 to drive the flywheel 103 to rotate. When the flywheel 103 rotates, due to the presence of the magnetic wheel 102, magnetic resistance will be generated between the flywheel 103 and the magnetic wheel 102, thereby forming resistance.

[0028] Moreover, when the lifting member 3 rises, the elastic rope 8 connected to its bottom is stretched, and the elastic rope 8 is guided by the second guide wheel 9 and the third guide wheel 6 to ensure that it maintains linear motion during the stretching process. The end of the elastic rope 8 away from the lifting member 3 is fixedly connected to the inside of the fitness equipment.

[0029] In the process of pulling the pull rope 4, in addition to the resistance provided by the magnetic resistance, the elastic rope 8 also provides additional elastic resistance. As the pull rope 4 is pulled, the magnetic resistance and the resistance of the elastic rope 8 work together to form a composite resistance, which increases the difficulty of training. When the user releases the pull rope 4, the lifting member 3 descends back to the initial position with the help of the restoring force of the elastic rope 8. At the same time, the pull belt 104 drives the flywheel 103 to rotate in the opposite direction, and the magnetic resistance comes into play again.

[0030] When the magnetic resistance mechanism 1 is working, the user starts to pull the pull cord 4, which will cause the lifting member 3 connected thereto to rise. The rise of the lifting member 3 will drive the pull belt 104 to move. The other end of the pull belt 104 is connected to the flywheel 103, so the flywheel 103 also starts to rotate. As the flywheel 103 rotates, the relative movement between it and the fixed magnetic wheel 102 will generate magnetic resistance. This magnetic resistance is caused by the electromagnetic interaction between the magnet in the magnetic wheel 102 and the flywheel 103. When the user stops pulling the pull cord 4 and gradually releases it, the pull belt 104 will drive the flywheel 103 to rotate in the opposite direction, and the magnetic resistance will come into play again, helping to slow down and smoothly return to the starting state.

[0031] During the process of using the elastic rope 8 to assist, when the lifting member 3 rises, the elastic rope 8 connected thereto is also stretched. The elastic rope 8 provides additional elastic resistance when stretched. The elastic rope 8 is guided by the second guide wheel 9 and the third guide wheel 6 to ensure that it can move smoothly in a straight line during the stretching process. When the user stops pulling the pull rope 4 and gradually releases it, the restoring force of the elastic rope 8 will cause the lifting member 3 to drop back to its initial position, and the elastic rope 8 provides a greater pullback force.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
