The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0041] The present application will be further described in conjunction with the accompanying drawings and specific embodiments.

[0042] Embodiment 1

[0043] As Figures 2-10As shown, this embodiment provides a trainer 100 with a guiding device, including a trainer body 60, a resistance mechanism 10, a force-applying component 50, a pull-end rope 30, a pulley system 40, a resistance-end rope 101, and a guiding device 20. The force-applying component 50 is disposed on the trainer body 60. The resistance mechanism 10 is connected to the force-applying component 50 through the resistance-end rope 101, the guiding device 20, the pull-end rope 30, and the pulley system 40, for providing training resistance in the trainer. The force-applying component 50 can be, for example, a handle, a straight pull bar, a curved pull bar, a bench press handle, etc. The pull-end rope 30 and the resistance-end rope 101 can typically be ropes with an inner steel cable and an outer plastic sheath.

[0044] A guide device 20 is mounted on the main body 60 of the trainer. The main body 60 of the trainer includes an upper support 62 and a lower support 61, and the guide device 20 is mounted between the upper support 62 and the lower support 61. The guide device 20 includes a guide rod 23, a sliding seat 22, a guide rod sleeve 21, an upper limit device 24, and a protective cover 25. There are two guide rods 23 arranged in parallel, and the two ends of the guide rods 23 are respectively mounted to the upper support 62 and the lower support 61. The sliding seat 22 is slidably sleeved on the guide rod 23. The side of the sliding seat 22 away from the resistance mechanism 10 is defined as the first side, and the side of the sliding seat 22 closer to the resistance mechanism 10 is defined as the second side. The resistance end rope 101 is connected to the second side of the sliding seat 22. The first side of the sliding seat 22 is connected to one end of the pulling end rope 30, and the other end of the pulling end rope 30 is connected to the force application member 50 through the pulley group 40. When a user trains with the device, a force is applied to the force-applying component 50, causing the pulling end rope 30 to move. The sliding seat 22 slides up and down along the guide rod 23 under the influence of the pulling end rope 30. One side of the sliding seat 22 is connected to the resistance end rope 101. Thus, the resistance end rope 101 moves under the guidance of the sliding seat 22 and the guide rod 23, preventing the rope from rubbing against the edges of other components and greatly improving rope durability. Compared to existing fitness equipment with motor-driven resistance mechanisms that guide the rope through guide rings or guide wheels, this embodiment prevents relative friction between the rope and the guide rings or guide wheels, preventing wear on the outer plastic sleeve of the rope and affecting its lifespan, further improving rope durability.

[0045] In this embodiment, there are two guide rods 23. In other embodiments, there may be one, three, or more guide rods, which are also feasible technical solutions.

[0046] Reference Figures 3-4 as well as Figures 5-6In this embodiment, a first connecting portion 222 is provided on the first side of the sliding seat body 221, which is used to fixally connect to one end of the pulling end rope 30. A second connecting portion 223 is provided on the second side of the sliding seat body 221, which is used to fixally connect to one end of the resistance end rope 101. For example, threaded joints can be provided at one end of the resistance end rope 101 and one end of the pulling end rope 30, and threaded mating structures corresponding to the threaded joints can be provided on the first connecting portion 222 and the second connecting portion 223 to achieve connection.

[0047] The guide rod 23 is a round rod, offering good guiding performance, low resistance, and easy installation. The guide rod 23 is made of metal, such as steel, providing high structural strength. The sliding seat 22 includes a sliding seat body 221, which has two guide holes 225 for the guide rod 23 to pass through. The sliding seat 22 also includes a guide sleeve 224, which is connected to the sliding seat body 221. Alternatively, the guide sleeve 224 and the sliding seat body 221 can be integrally formed. The guide holes 225 extend into the guide sleeve 224, providing a longer guiding distance for the movement of the sliding seat 22, thus achieving a more stable guiding effect.

[0048] The first connecting part 222 and the second connecting part 223 are located between the two guide holes 225, and the resistance mechanism 10 is located between the two guide rods 23, with the resistance mechanism 10 positioned below the two guide rods 23. The outlet 111 of the resistance mechanism 10 is positioned opposite to the second connecting part 223, thereby enabling better guidance. The width of the housing 11 of the resistance mechanism 10 is the same as the width of the gap between the two guide rods 23, resulting in a more compact size and easier installation and positioning.

[0049] A guide rod sleeve 21 is fitted over the lower part of the guide rod 23. The guide rod sleeve 21 protects the lower part of the guide rod 23 and also serves as a lower limiting device. The upper end face of the guide rod sleeve 21 abuts against the sliding seat 22, thereby limiting the lower travel of the sliding seat 22. The lower limiting device allows the lower limit position of the sliding seat 22 to be aligned with the lower limit position of the sliding seat 22. Figure 1 The lower limit position of the sliding seat of the trainer using counterweights shown is consistent, thus maximizing compatibility with the traditional counterweight trainer architecture, eliminating the need for additional development and design, and greatly reducing hardware development costs.

[0050] In addition, refer to Figures 1-3The height design of the guide sleeve 21 ensures that the upper end of the guide sleeve 21 after installation with the guide rod 23 is at the same height as the upper end of the topmost piece of the counterweight 2. Thus, the lower limit position of the sliding seat 22 in this embodiment is at the same height as the lower limit position of the sliding seat 3 of the trainer 1 using the counterweight 2. Consequently, the length of the pulling end rope 30 is consistent. There is no need to readjust the pulling end rope and its pulley group and other parts and installation structure of the traditional counterweight trainer architecture. The parts are more interchangeable, the installation and debugging are more convenient, and the production cost is reduced.

[0051] A protective cover 25 connects the two guide rod sleeves 21. The protective cover 25 has a cross-section in the shape of an "[" and has high structural strength. The protective cover 25 can protect the resistance end rope 101 of the resistance mechanism 10, preventing accidental contact and injury by the user. The protective cover 25 includes at least the side surfaces 252 of the cover body surrounding the two guide rod sleeves 21 and the front surface 251 of the cover body facing the user. The upper end surface of the protective cover 25 is flush with the upper end surface of the guide rod sleeves 21, so the protective cover 25 can also serve as a lower limit device to limit the downward movement of the sliding seat 22. A mounting base plate 611 is provided on the lower support 61. The mounting base plate 611 is used to support the installation of the resistance mechanism 10, which not only makes the installation of the resistance mechanism 10 more stable, but also improves the appearance of the equipment during use.

[0052] Reference Figures 3-4 as well as Figures 7-8 An upper limit device 24 is provided on the upper part of the guide rod 23 to limit the upper travel of the sliding seat 22. The upper limit device 24 includes a cylindrical body 241 and a limiting plate 242 connected to each other. The cylindrical body 241 is a hollow tubular structure, and the limiting plate 242 has a through hole. The guide rod 23 passes through the cylindrical body 241 and the limiting plate 242, and the limiting plate 242 is located at the end of the cylindrical body 241 facing the sliding seat 22. A threaded structure 244 is provided on the side wall of the cylindrical body 241. The threaded structure 244 can be a nut or an internal thread formed directly on the side wall of the cylindrical body 241. The upper limit device 24 also includes a fastening screw 243, which cooperates with the threaded structure 244 so that one end of the fastening screw 243 can be screwed into the inner cavity of the cylindrical body 241 and press against the guide rod 23, thereby fixing the upper limit device 24 to the guide rod 23.

[0053] Reference Figures 1-4The components of the trainer 100 in this embodiment have a high degree of commonality with those of the trainer 1 using counterweights 2. Therefore, it is easy to convert between the two configurations. This helps the factory to produce according to customer needs or facilitates users to replace and upgrade their existing trainers. For example, if the trainer 100 using the resistance mechanism 10 in this embodiment is to be converted into the trainer 1 using counterweights 2, two guide rods 23 can be installed on the lower support 61. Then, multiple layers of counterweights 2 and their accessories can be fitted onto the two guide rods 23 from top to bottom. After the required number of layers of counterweights 2 are reached, a sliding seat 22 is fitted on top of the counterweights 2. Then, a limiting device and a device for fixing and connecting to the upper support 62 are installed, and a rope assembly is connected. The installation and replacement can be completed. The installation is very convenient and efficient.

[0054] The resistance mechanism 10 includes a housing 11, a motor 18, a self-locking drive mechanism 14, a controller 16, a hoisting mechanism 19, and a guide roller 17. The motor 18 is used to provide motion resistance in the trainer, for example, as a resistance source for a stretching trainer. The controller 16 is electrically connected to the motor 18 and is used to control the magnitude or direction of the resistance provided by the motor 18.

[0055] The motor 18, the self-locking drive mechanism 14, and the controller 16 are mounted inside the housing 11. The housing 11 has heat dissipation holes 12 and a cooling fan 13 is fixedly installed to enhance heat dissipation for the motor 18, the self-locking drive mechanism 14, and the controller 16. The motor 18 includes a stator assembly 181 and a rotor assembly 182. The stator assembly 181 is fixedly mounted to the housing 11. The rotor assembly 182 is rotatable relative to the stator assembly 181.

[0056] The winch mechanism 19 is used to wind the rope at the force-applying end of the fitness equipment. The winch mechanism 19 is drive-connected to the rotor assembly 182 of the motor 18. The winch mechanism 19 can be directly connected to the rotor assembly 182, or it can be connected to the rotor assembly 182 via a speed-changing assembly, allowing the winch mechanism 19 to rotate with the rotor assembly 182. The winch mechanism 19 is used to wind the rope at the force-applying end of the fitness equipment, thereby providing resistance to the equipment. Figures 9-10 As shown, a cable outlet hole 111 is provided on the top of the housing 11 for the cable to pass through. Preferably, the motor 18 is a servo motor, which allows for more precise control over resistance adjustment. The self-locking drive mechanism 14 is used to perform locking and unlocking operations on the rotation of the hoisting mechanism 19.

[0057] Reference Figures 9-10A guide roller 17 is provided between the cable outlet 111 and the hoisting mechanism 19. The rope passes over the guide roller 17 and then exits the housing 11 through the cable outlet 111. The guide roller 17 guides the rope on the hoisting mechanism 19 as it exits the housing 11, ensuring that the rope is accurately aligned with the cable outlet 111 and preventing it from scraping against the housing 11 and causing wear that could affect its service life.

[0058] In this embodiment, the self-locking drive mechanism 14 is electrically connected to the controller 16. Upon receiving a control signal from the controller 16, the self-locking drive mechanism 14 can also perform locking and unlocking operations on the rotation of the hoisting mechanism 19. When the fitness equipment is set to at least one of the following states, the controller 16 sends a control signal to lock the rotation of the hoisting mechanism: temporary departure state, power-off state, or transport state. Thus, when a user needs to temporarily leave or needs to turn off the fitness equipment, they can actively lock the resistance mechanism to prevent children from touching the equipment and causing safety risks. Furthermore, during transport, the resistance mechanism of the fitness equipment can also be actively locked to prevent damage to the resistance mechanism caused by continuous vibration during transport.

[0059] Reference Figures 9-10 The resistance mechanism 10 also includes a human-machine interface device 15, which is mounted on the housing 11. The human-machine interface device 15 is used to adjust and display the operating parameters of the resistance mechanism 10. Specifically, the human-machine interface device 15 is a rotary knob display assembly 15, which is electrically connected to the controller 16. The rotary knob display assembly 15 includes a rotary knob and a display device on the front of the rotary knob. The rotary knob can be used to adjust various operating parameters of the resistance mechanism 10, such as resistance, number of repetitions, and power. The display device on the front of the rotary knob, such as an electronic watch, can display multiple data such as resistance, number of repetitions, power, and maximum explosive force. The rotary knob display assembly 15 may include a processing chip and a memory, making it easy to use. It can record previous data and settings and save each exercise record, allowing users to download data without complicated operations, facilitating future analysis and research.

[0060] In this embodiment, the guide device 20 is used as an example in a resistance mechanism 10 with a motor. Of course, in other embodiments, the guide device 20 can also be used in other types of resistance mechanisms, such as resistance mechanisms with fan blades.

The force-applying component 50a is disposed on the trainer body 60a. The resistance mechanism 10 is connected to the force-applying component 50a through the resistance-end rope 101, the guiding device 20a, the pull-end rope 30a, and the pulley system 40a, for providing training resistance in the trainer. The force-applying component 50a can be, for example, a handle, a straight pull bar, a curved pull bar, a bench press handle, etc. The pull-end rope 30a and the resistance-end rope 101 can typically be ropes with an inner steel cable and an outer plastic sheath.

[0063] The guide device 20a is mounted on the main body 60a of the trainer. The guide device 20a includes guide rods 23, sliding seats 22, upper limit devices 24a, and lower limit devices 26. There are two guide rods 23 arranged in parallel, and the sliding seats 22 are slidably sleeved on the guide rods 23. The structure of the sliding seats 22 and the guide rods 23 is the same as in Embodiment 1, and will not be described again here.

[0064] The lower limit device 26 is a limiting plate structure, with both ends connected to the trainer body 60a. The lower end of the guide rod 23 can be mounted on the lower limit device 26, thus the lower end of the guide rod 23 is mounted to the trainer body 60a through the lower limit device 26. The upper end face of the lower limit device 26 can abut against the sliding seat 22, thereby limiting the downward movement of the sliding seat 22. The resistance mechanism 10 is located below the lower limit device 26, and the lower limit device 26 has a through hole for the resistance end rope 101 to pass through. The protective cover 27 is arranged around the periphery of the resistance mechanism 10, thereby protecting the resistance mechanism 10. The lower limit device 26 can serve as the upper plate of the protective cover 27, thus simplifying the structure and making the product more compact.
