Description

Pull-up training components and strength training equipment suitable for strength training equipment Technical Field

[0001] This invention relates to the field of strength training, and in particular to a tension training component and a strength training device suitable for strength training equipment. Background Technology

[0002] As people's living standards improve, the pace of life accelerates. Against this backdrop, more and more people are focusing on strength training, hoping to build a healthier and more energetic physique. Rope strength training, in particular, has garnered significant attention. Common rope strength training equipment includes double-arm flyes, lat pulldowns, power stations, and rowing machines. Furthermore, the emergence of motor-driven resistance training equipment has effectively solved the problem of traditional anaerobic strength equipment being purely mechanical and difficult to install at home. For example, our company's CN115888029A and CN219149132U eliminate the need for counterweights, significantly reducing the size and weight of the equipment and enabling its rapid adoption in homes.

[0003] However, current rope strength training equipment that uses motors as the resistance source often connects the rope directly to the resistance motor. While this method allows the tension to be directly applied to the motor, in actual training, because the trainee's movements are not perfectly standard and have a certain degree of dynamism, it is difficult to guarantee that the tension is transmitted smoothly and accurately to the motor with each connection. This may result in the trainee not receiving precise and stable resistance feedback, affecting training effectiveness. Furthermore, rope training is generally based on double-ended ropes, and most products on the market achieve this through two motor resistance systems. This also leads to issues such as inconsistent force at both ends of the two motors and poor rope durability. Specifically, different parts of the rope will experience inconsistent forces due to differences in stretching speed, angle, and other factors. Moreover, when the force output from the motor is transmitted through the rope, the elasticity of the rope itself and the stability of the motor operation may cause fluctuations in the magnitude of the force between the two motors. This not only affects the trainee's accurate perception of resistance but may also distort the training movements, failing to achieve the desired training effect. Meanwhile, the rope is prone to wear and tear when it is connected to the motor and subjected to tension for a long time, especially when it is used frequently or when performing heavy weight or high-frequency tension training. This causes the rope fibers to wear down gradually, reducing its strength and service life. Once the rope wears down and breaks, the dual-motor system will not only interrupt training but may also cause accidental injury to the trainee due to the complexity of abnormal judgment by the control of the two sets of motors. Summary of the Invention

[0004] The purpose of this invention is to provide a tension training component and a strength training device suitable for rope electronic strength training equipment. The tension training component uses a single motor resistance as the resistance source and achieves double-end rope output through a flexible guide rail and a movable pulley system. The deviation that occurs in the pulley system during reciprocating motion is reduced by the deformation of the flexible guide rail to reduce swaying and jamming, and provides natural double-end force balance tension transmission performance in a low-cost manner.

[0005] To achieve the above objectives, this technical solution provides a tension training component suitable for strength training equipment, installed on the main body of the strength training equipment, including: a movable pulley transmission structure, wherein the movable pulley transmission structure includes a flexible guide rail and a movable pulley assembly slidably fitted on the flexible guide rail, the two ends of the flexible guide rail being fixed to the main body of the strength training equipment to define a sliding stroke area for the movable pulley assembly to slide; a pull cable connected to the movable pulley assembly for pulling the movable pulley assembly to slide along the flexible guide rail within the sliding stroke area; and a resistance motor, wherein the winding shaft of the resistance motor is drivenly connected to the movable pulley assembly through a resistance source pull rope, for providing adjustable resistance to the pull cable through the movable pulley transmission structure.

[0006] This solution provides a power training station, including: a power training station body; a tension training component as described above placed on the power training station body; and a puller, wherein the puller connects to one end of a pull line that is not connected to the movable pulley block, for providing tension to the pull line.

[0007] This solution provides a full-function electronic dumbbell bench, including: a footboard, a standing area on top, and an extension mounting structure at at least one end of the standing area along its length for mounting extension functional components; a resistance training component as described above, fixed to the footboard; and a handle connected to the resistance training component.

[0008] This solution provides a full-function electronic dumbbell bench, including: a footboard, a standing area on top, and extension mounting structures at both ends of the standing area along its length for mounting extension functional components;

[0009] A tension training assembly as shown above, fixed to the pedal; a handle connected to the tension training assembly;

[0010] The extended functional component is a bench press accessory set, which includes: a bench with a flat surface at the top for the user to lie down on, and bench legs at the bottom for mounting on the footrest and supporting the user on the ground; a support bar with an extended mounting structure at the bottom that can be installed on the footrest, and an adjustable bracket at the top for holding dumbbell bars, the adjustable bracket and support bar being telescopically coordinated and locked by an adjustable rotating component; dumbbell bars with connectors at both ends along their length; and a connecting cable with one end detachably connected to the connector and the other end detachably connected to the pull ring of the footrest.

[0011] This solution provides a high-pull electronic dumbbell bench, comprising: a footboard with a standing area at the top, both ends of which have extension installation structures for mounting extension functional components; a resistance training component fixed to the footboard as shown above; and a pull handle connected to the resistance training component; wherein the extension functional component is a high-pull accessory assembly, which includes: an extension base connected to the front or rear end of the footboard; a high-pull bracket fixed to the extension base at the bottom and equipped with a fixed pulley at the top; a high-pull connecting cable, one end of which is connected to a cable connecting block, and the other end which engages with the fixed pulley and connects to the pull rod; and a pull rod located above the footboard.

[0012] This solution provides a rowing machine, including: a foot pedal with a standing area at the top, and extension mounting structures at both ends of the standing area along its length for mounting extension functional components; a resistance training component fixed to the foot pedal as shown above; and a handle connected to the resistance training component. The extension functional components are rowing machine accessory sets, which include: a support frame with a connecting part at the bottom for connecting the foot pedal, and a pull rod and a mounting seat for mounting a guide slider at the top; a guide slider mounted on the mounting seat with a cable hole for the cable of an electronic dumbbell bench to pass through, and a cable groove at the edge of the cable hole for the cable to enter; a foot pedal, one end of which is movably connected to the support frame, and the other end of which has a mounting groove for mounting a slide rail; a slide rail, one end of which engages with the mounting groove, and the other end of which is supported on the ground by a bottom bracket, forming a track for moving a seat; and a seat mounted on the slide rail, capable of moving back and forth along the length of the slide rail.

[0013] Compared with existing technologies, this technical solution has the following characteristics and beneficial effects:

[0014] 1. The unique design of the flexible guide rail in this application's resistance training component allows it to better adapt to different movement trajectory requirements. During training, the trainee pulls the movable pulley system along the sliding stroke area limited by the flexible guide rail using a suspension cable, overcoming the resistance of the resistance cable to achieve the effect of strength training. Whether it's straight stretching, curved stretching, or complex multi-angle stretching movements, the flexible guide rail provides smooth guidance, ensuring the accuracy and stability of force transmission. In other words, any deviation in the movable pulley system during reciprocating motion is reduced by the deformation of the flexible guide rail, minimizing wobbling and jamming. This solution's combination of movable pulleys and flexible guide rails perfectly solves the inherent difficulties of traditional movable pulley metal guide rails, such as high cost and uncomfortable left-right guide rail jamming during reciprocating motion. Compared to traditional rigid guide rails, it avoids the jamming sensation caused by asynchronous ends of rigid guide rails, allowing users to perform various resistance training movements more naturally, thereby better activating target muscle groups and improving training effectiveness.

[0015] 2. This application's resistance training component uses only a single motor to achieve double-end rope output, solving the problems of high cost, poor force balance, and poor safety associated with traditional dual-motor solutions. In other words, by employing flexible guide rails and movable pulley systems, a low-cost single-motor resistance source device can achieve double-end rope output, significantly reducing equipment costs and improving ease of use compared to solutions on the market. Furthermore, the advantage of using a single motor is that if the motor's cable breaks, the absence of a single cable ensures no retraction force on the trainee's hand, minimizing the probability of injury and further enhancing the safety of the resistance training component.

[0016] 3. The resistance training component of this application can be assembled onto various rope-output strength training devices, including single-hand and double-hand rope retraction and release training devices, barbell bar retraction and release electronic barbell devices with ropes at both ends, high-position cable lat pulldown training machines, electronic power stations, electronic dumbbell benches, electronic resistance rowing machines, and all other equipment that uses rope retraction and release training, providing low-cost electronic strength training devices.

[0017] 4. The electronic dumbbell bench applicable to this application improves upon the pedal design by eliminating the folding structure and reducing the size of the pedal, leaving only sufficient standing and mounting areas. The handles are positioned at both ends of the standing area's length, and the resistance motor is located in the mounting area, ensuring that the axes of the resistance motor and the winding shaft are parallel to the pedal's length. This further shortens the pedal width, allowing the pedal's width and length to reach a minimum size while meeting fitness needs, significantly reducing costs. Furthermore, a groove at the bottom of the pedal is used to install a pulley system, enabling the winding and unwinding of the cable, providing adjustable resistance training suitable for various fitness needs.

[0018] 5. This application reserves an extension installation structure in the standing area of ​​the pedal, which can install various extension functional components, such as bench press accessory groups, high pull accessory groups, rowing machine accessory groups, etc. This application uses the resistance source rope as the resistance source. When one or both pull handles are pulled by the user at the same time, they will drive the movable pulley group to move on the flexible guide rail (from front to back). The movable pulley group moves back to pull the resistance source rope. Since the resistance source rope is connected to the resistance source, the resistance can be adjusted by adjusting the resistance of the resistance source, thereby achieving the purpose of strength training. It can be used for training in various body positions to meet the various needs of fitness enthusiasts. Moreover, it can be arbitrarily combined, replaced and assembled. It is easy to operate, inexpensive, and easy to popularize.

[0019] 6. In this application, the axial direction of the winding shaft of the resistance motor is set perpendicular to the axial direction of the first fixed pulley, and the position of the first fixed pulley is adjusted to one side below the winding shaft. This ensures that the resistance source pull rope will not contact the side of the central groove of the first fixed pulley during winding or unwinding, thereby avoiding wear on the resistance source pull rope. This not only prevents the resistance source pull rope from breaking due to wear, but also improves the smoothness of use.

[0020] 7. In use, the extension base is first installed at the front or rear of the pedal of the electronic dumbbell bench, mainly to be close to the original location of the handle. The handle is then removed (from the cable connector). Next, the high-pull bracket is installed on the extension base, the high-pull connecting cable is installed, and then connected to the cable connector and pull rod of the electronic dumbbell bench respectively, thus completing the assembly. The user can then stand on the original electronic dumbbell bench and use the built-in resistance source of the bench to perform high-pull exercises. When high-pull exercises are not needed, the high-pull accessory assembly can be removed, restoring the bench to its original state. This design offers advantages such as simple structure, easy assembly and disassembly, and low cost.

[0021] 8. When using this application, first install the support rod on the extended mounting structure of the electronic dumbbell bench's pedals. Remove the handle of the electronic dumbbell bench from the cable connector. Then, position the bench so that it is perpendicular to the pedals and does not contact them, reducing damage to the pedals. Finally, place the dumbbell bars on the adjustment frame, adjust the height of the adjustment frame, and then connect the pull ring of the electronic dumbbell bench to the dumbbell bars using the connecting cable. Bench press exercises can then be performed. When bench press exercises are not needed, the bench press accessory assembly of this application can be disassembled, restoring the electronic dumbbell bench. This design offers advantages such as simple structure, easy assembly and disassembly, and low cost. Alternatively, only the bench can be removed for standing strength training. Due to the support rod and adjustment frame, even if the dumbbell bars fall, they will be stopped by the adjustment frame, preventing injury to the user and significantly improving safety.

[0022] 9. This application allows the device to be installed on the footrest of an electronic dumbbell bench via the connecting part of the support frame. The handle of the electronic dumbbell bench is removed, and the cable is inserted from the cable threading groove into the guide slider. The guide slider is then installed on the mounting base and connected to the handle (or the guide slider can be installed first, followed by the cable). The footrest is then placed on the footrest of the electronic dumbbell bench, and one end of the slide rail is installed in the mounting groove of the footrest, with the other end supported on the ground. This completes the assembly of the rowing machine. Then, simply turn on the motor or magnetic powder controller of the electronic dumbbell bench to adjust the resistance for rowing training. When the rowing machine is not in use, the rowing machine accessory assembly of this application can be disassembled, restoring it to its original state as an electronic dumbbell bench. This design offers advantages such as simple structure, easy assembly and disassembly, and low cost. The way the slide rail and footrest work together greatly facilitates the assembly and disassembly of the slide rail without affecting its stability, significantly reducing the difficulty of assembling and disassembling the rowing machine accessory assembly.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0048] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0049] Example 1: Pull training component suitable for strength training equipment

[0050] As shown in Figure 1, this solution provides a resistance training component suitable for strength training equipment, which is installed on the main body of the strength training equipment and includes:

[0051] The movable pulley system transmission structure 3 includes a flexible guide rail 32 and a movable pulley system 31 that is slidably fitted on the flexible guide rail 32. The two ends of the flexible guide rail 32 are fixed to the main body of the strength training equipment and define a sliding stroke area for the movable pulley system 31 to slide.

[0052] The pull wire 5 connected to the movable pulley block 31 is used to pull the movable pulley block 31 to slide along the flexible guide rail 32 within the sliding stroke area;

[0053] The resistance motor 2, wherein the winding shaft 26 of the resistance motor 2 is driven to the pulley block 31 via the resistance source pull rope 4, and is used to provide adjustable resistance to the pull rope 5 through the pulley block transmission structure 3.

[0054] The tension training component provided in this solution offers adjustable resistance via a resistance motor 2. The pull cable 5 and the resistance source rope 4 are connected to opposite sides of a movable pulley system 31. This ensures that when the trainee pulls the movable pulley system 31 using the pull cable 5, they must overcome the resistance of the resistance source rope 4, thus achieving the effect of strength training. Unlike the traditional method of directly applying the pull cable to the resistance motor, this solution uses the movable pulley system 31 to transmit the force of the pull cable 5. This allows for a more even distribution of the tension among the components connected to the movable pulley system 31, especially on the resistance source rope 4. When the trainee pulls the pull cable 5, the tension is evenly applied to the resistance source rope 4 through the movable pulley system 31, avoiding the potential for excessive or insufficient localized force as in direct connection methods. This helps maintain the stability of force transmission, allowing the trainee to more accurately feel the resistance during the pulling process and to train according to the expected movement trajectory, thereby improving training effectiveness. Meanwhile, the force transmitted through the movable pulley system 31 reduces the stress on the resistance source rope 4, thereby extending its service life. When the trainee pulls the cable 5, the movable pulley system 31 shares part of the tension, reducing the actual tension borne by the resistance source rope 4. In long-term strength training, this reduces the risk of wear and breakage of the resistance source rope 4 due to frequent exposure to large tensions.

[0055] It is particularly important to note that the flexible guide rail 32 in the tension training component is a non-rigid guide rail; that is, the flexible guide rail 32 is a deformable guide rail. The biggest difference between the flexible guide rail 32 provided in this solution and traditional rigid metal guide rails is its deformability. Specifically, the flexible guide rail 32 is a deformable rope-like guide rail, made of a material selected from metal wire, various fiber materials, stainless steel wire, or any combination thereof. Because the flexible guide rail 32 is a flexible material, it can be used to provide a flexible guide rail for the movable pulley system 31. Specifically, both ends of the flexible guide rail 32 are fixed to the ends of the sliding stroke area of ​​the movable pulley system 31 to provide flexible guidance for the movable pulley system 31 within the sliding stroke area, allowing the movable pulley system 31 to slide along the flexible guide rail 32.

[0056] It should be noted that the resistance training component of this solution for strength training equipment has only one resistance motor 2. This single resistance motor 2 is connected to a single movable pulley system via a resistance source rope 4, thus achieving a single-motor, double-end output design. However, this single-motor, double-output design means that the force exerted by both ends pulling the rope 30 acts on the same single motor. To avoid instability of the movable pulley system due to the imbalance of forces at both ends, this solution further selects a flexible guide rail 32 instead of a rigid guide rail. This is because when the movable pulley system 31 changes its stroke relative to the resistance motor 4 under the action of the rope 5, the direction of the force exerted by the rope 5 deviates from the axial direction of the movable pulley system 31 and the resistance motor 4. If a rigid guide rail were used, it would cause strong collisions and friction between the movable pulley system and the rigid guide rail, which would not only cause instability for the trainee... Overcoming the resistance of the resistance source, the adjusting resistance of the pull rope 4, also requires overcoming the resistance between the movable pulley block 31 and the rigid guide rail. This approach would severely damage both the movable pulley block 31 and the rigid guide rail. In contrast, this solution prioritizes the use of the flexible guide rail 32. This provides guidance to the movable pulley block 31 while avoiding damage to it. Furthermore, the flexible guide rail 32 significantly reduces the cost and portability of the strength training components. It also allows the single-motor pulley system to operate more smoothly and stably. Compared to metal pulley guide rails, it is much cheaper and offers a significant improvement in smoothness.

[0057] In addition, it is worth mentioning that because this solution uses a single motor with dual outputs, it can avoid the situation where the trainee's hand is injured by the retraction force of the cable when the cable breaks. This solves the problems of high cost, poor force balance at both ends, and poor safety of the dual motor dual output method.

[0058] In some embodiments, the two ends of the flexible guide rail 32 are fixed to the two ends of the sliding stroke area of ​​the movable pulley group 31, and at least one end of the flexible guide rail 32 is provided with a tension adjustment structure 321, which is used to adjust the tightness of the flexible guide rail 32. Since this solution provides a flexible guide rail 32, the tightness of the flexible guide rail 32 is adjustable. The tighter the flexible guide rail 32 is, the stronger the guiding and limiting force on the movable pulley group 31 is; conversely, the looser the flexible guide rail 32 is, the weaker the guiding and limiting force on the movable pulley group 31 is.

[0059] Specifically, in some embodiments, the tension adjustment structure 321 is selected as a threaded structure. In this case, the tension adjustment structure 321 includes an external thread provided at one end of the flexible guide rail 32, and a nut that mates with the external thread. The tightness of the flexible guide rail 32 is adjusted by screwing the nut onto the external thread. At this time, the flexible guide rail with the external nut at one end acts as a screw. The nut moves along the screw towards the flexible guide rail, and the movement of the nut directly tightens the flexible guide rail, thereby strengthening the guiding and limiting force on the movable pulley assembly 31. Conversely, when the screw is rotated counterclockwise, the nut moves in the opposite direction along the screw, which relaxes the tension on the flexible guide rail 32, making the flexible guide rail looser. Correspondingly, the guiding and limiting force on the movable pulley assembly 31 is weakened.

[0060] In other embodiments, the tension adjustment structure 321 is selected as a spring structure. In this case, the tension adjustment structure 321 includes a spring connector disposed at one section of the flexible guide rail, and an active spring assembly connected to the spring connector. The tension of the flexible guide rail 32 is adjusted by adjusting the tension of the active spring assembly. In some embodiments, the active spring assembly is a gas spring filled with high-pressure gas. It consists of a cylinder, a piston rod, a control valve, and a sealing device. One end of the piston rod extends from the cylinder and is connected to the flexible guide rail via the spring connector. When it is necessary to actively adjust the tension of the flexible guide rail, the control valve is opened to increase or decrease the pressure of the gas inside the gas spring as needed. If the gas pressure is increased, the piston rod of the gas spring will extend, applying tension to the flexible guide rail to tighten it. When the gas pressure is decreased, the piston rod will retract, causing the flexible guide rail to loosen. In some embodiments, the active spring assembly includes a butterfly spring and an adjusting bolt connected to the butterfly spring. The butterfly spring is connected to the flexible guide rail 32. When it is necessary to actively adjust the tension of the flexible guide rail, the adjusting bolt is rotated. When the adjusting bolt is screwed in, its head applies pressure to the disc spring, causing the disc spring to deform and compress. The reaction force generated by the disc spring is transmitted to the flexible guide rail through the connection point with the flexible guide rail, tightening it and thus adjusting the tightness of the flexible guide rail. When the adjusting bolt is screwed out, the pressure on the disc spring decreases, and it will rebound according to its own elasticity, causing the flexible guide rail to loosen.

[0061] In some embodiments, the tension training component includes one flexible guide rail 32. Preferably, the flexible guide rail 32 passes through the center of the movable pulley group 31 to serve as the flexible guide rail of the movable pulley group 31. In other embodiments, the tension training component includes two flexible guide rails 32 located at the left and right ends of the movable pulley group 31. Preferably, the flexible guide rails 32 are symmetrically arranged and pass through the center of the movable pulley group 31 to serve as the flexible guide rail of the movable pulley group 31.

[0062] As shown in Figure 2, the movable pulley block 31 provided in this solution includes a movable pulley fixing block 311 and a movable pulley 312 disposed inside the movable pulley fixing block 311. The pull wire 5 is wrapped around the outer periphery of the movable pulley 312 to cooperate with the movable pulley 312. The pull wire 5 pulls the movable pulley fixing block 311 along the flexible guide rail 5 by acting on the movable pulley 312.

[0063] In some embodiments, the movable pulley assembly 31 has one and only one movable pulley 312. The same pull cable 5 is wound around the outer periphery of the movable pulley 312 to cooperate with it. Both ends of the pull cable 5 are connected to the handle to achieve a dual-output end effect. In this case, preferably, the movable pulley 312 is positioned at the center of the movable pulley fixing block 311 so that the pull cable 5 can apply force evenly to the movable pulley assembly 31.

[0064] In other embodiments, the movable pulley block 31 is provided with two or more movable pulleys 312, and the same pull wire 5 is sequentially wrapped around the outer periphery of the multiple movable pulleys 312 to cooperate with the movable pulleys 312. Preferably, if the movable pulley block 31 has only two movable pulleys 312, the two movable pulleys 312 are symmetrically arranged.

[0065] In some embodiments, the movable pulley fixing block 311 has at least one through hole through which the flexible guide rail 32 passes. In some embodiments, at least one end of the through hole of the movable pulley fixing block 311 is provided with a sliding bushing 313, in which case the sliding bushing 313 is located at the end of the through hole of the movable pulley fixing block 311. The shape and size of the sliding bushing 313 match the shape and size of the flexible guide rail 32, and are used to allow the flexible guide rail to pass through the sliding bushing 313 so that the movable pulley fixing block 311 can slide along the flexible guide rail 32.

[0066] Preferably, the movable pulley fixing block 311 has symmetrical through holes at both ends, and each through hole has a sliding bushing 313 on its end side. The sliding bushing 313 and the through hole slide in cooperation with the flexible guide rail 32. The advantage of this arrangement is to ensure the stability of the sliding of the movable pulley fixing block 311.

[0067] Preferably, the inner surface of the sliding bushing 313 in this solution is a smooth surface.

[0068] In other embodiments, the middle end of the through hole of the movable pulley fixing block 311 is provided with an inner bushing whose inner diameter matches that of the flexible guide rail. The inner diameter of the inner bushing matches the diameter of the flexible guide rail to facilitate the relative sliding movement of the flexible guide rail and the movable pulley assembly. In some embodiments, the end side of the inner bushing abuts against the end side of the sliding bushing 313 at both ends.

[0069] In addition, to avoid unnecessary collisions during the movement of the movable pulley block 31, the movable pulley block transmission structure 3 of this solution includes a limiting component 36, wherein the limiting component 36 is set in the sliding stroke area defined by the hanging rope 32 and is set relative to the movable pulley block 31, and is used to limit the movement stroke of the movable pulley block 31.

[0070] Preferably, the limiting component 36 is positioned between the movable pulley block 31 and the resistance motor 2 to prevent the movable pulley block 31 from moving further toward the resistance motor 2. In other words, when the pull cable 5 does not apply tension to the movable pulley block 31, the resistance source pull rope 4 tends to coil under the action of the resistance motor 2. At this time, the resistance source pull rope 4 pulls the movable pulley block 31 toward the resistance motor 2, and the limiting component 36 is positioned between the movable pulley block 31 and the resistance motor 2 to prevent the movable pulley block 31 from colliding with the resistance motor 2.

[0071] Of course, in some embodiments, the limiting component 36 is located at the end of the movable pulley group 31 away from the resistance motor 2. In this case, the limiting component 36 can prevent the movable pulley group 31 from colliding with other parts of the strength training device and causing unnecessary damage when the force of the pull wire 5 is too large.

[0072] In some embodiments, the limiting component 36 is designed as a limiting platform fixed at the end position of the sliding stroke area, and the limiting platform is arranged relative to the movable pulley group 31 to prevent the movable pulley group 31 from having further movement stroke.

[0073] Preferably, a flexible buffer block 314, such as a rubber pad, is placed on the side of the movable pulley fixing block 311 near the limiting component 36. In particular, the flexible buffer block 314 on the side of the movable pulley fixing block 311 connected to the resistance source pull rope 4 causes the movable pulley fixing block 311 to move towards the resistance motor due to the winding action of the resistance source. The flexible buffer block 314 provides a good buffering effect, thereby reducing impact noise and protecting the movable pulley fixing block 311.

[0074] In other embodiments, the movable pulley block transmission structure 3 includes a position sensing control component 37, which is disposed within the sliding stroke area of ​​the movable pulley block 31 and is used to sense the position of the movable pulley block 31.

[0075] The position sensing control component 37 of this solution includes a position sensor 371 for sensing the position of the movable pulley assembly 31 and a sensing control board 372 that is communicatively connected to the sensor 371. The position sensor 371 is set within the sliding stroke area of ​​the movable pulley assembly 31 to sense the position of the movable pulley assembly 31 and transmits the sensed position to the sensing control board 372 to respond. The response method includes, but is not limited to, controlling the movable pulley assembly 31 to stop the stroke change. The advantage of this is that the movable pulley assembly 31 can be stopped by electronic control during rapid descent, avoiding severe impact.

[0076] Specifically, in this solution, the position sensor 371 is positioned near the end of the sliding travel area to detect when the movable pulley assembly 31 is about to approach the end of the sliding travel area. The position sensor 371 in this solution is an infrared sensor with a specific infrared travel range. When the movable pulley assembly 31 slides down or rises within the specific infrared travel range of the position sensor 371, the position sensor 371 detects the position of the movable pulley assembly 31 and transmits the information to the sensing control board 372.

[0077] In some embodiments, the position sensor 371 is disposed on the limiting component 36. In other embodiments, the position sensor 371 is disposed on the side of the limiting component 36 near the movable pulley assembly 31. In this case, the position sensor 371 can provide a timely warning when the movable pulley assembly 31 approaches the limiting component 36.

[0078] In this design, the pull line 5 and the resistance source pull rope 4 are respectively connected to both ends of the movable pulley fixing block 311. The movable pulley fixing block 311 is provided with a connecting ring on one end near the resistance source pull rope 4. One end of the resistance source pull rope 4 is connected to the connecting ring, and the other end is connected to the resistance motor 2, so that when the pull line 5 pulls the movable pulley group 31 to move, it needs to overcome the resistance provided by the resistance motor 2, thus achieving the purpose of strength training.

[0079] It should be noted that in some embodiments, the resistance source rope 4 is connected to the central axis of the movable pulley system 31. This has the advantage of making the movement trajectory of the movable pulley system 31 more stable when moving along the suspension rope 32. Unlike the slight swaying and deviation that may occur with non-central axis connections, the central axis connection allows the movable pulley system 31 to maintain a relatively regular straight-line movement. This is very important for trainees because a stable movement trajectory helps them better control the standardization of their training movements, enabling them to pull according to the expected movement path, thereby improving training effectiveness and reducing the risk of injury due to unstable movements. Furthermore, when the force is evenly distributed on both sides of the central axis, the pressure on each pulley, connection point, and other parts is relatively balanced. Compared to the localized excessive wear that may be caused by uneven force, this connection method can extend the service life of the movable pulley system and its connected components such as the suspension rope 32 and the resistance source rope 4.

[0080] As shown in Figure 3, the resistance motor 2 of this scheme includes a motor part 21 and a single-stage gear reducer 22 located at the output end of the motor part 21. The output end of the single-stage gear reducer 22 is directly driven and connected to the winding shaft 26. The resistance source pull rope 4 is wound on the winding shaft 26 so that the resistance source pull rope 4 is wound or unwound by the winding shaft 26.

[0081] Example 2: Power Bird Station

[0082] As shown in Embodiment 1 of this solution, the resistance training component suitable for strength training equipment can be used on a strength fly station. In this case, the strength training equipment is a strength fly station. Embodiment 2 provides an embodiment of a strength fly station, as shown in Figure 4. The strength fly station provided by this solution includes:

[0083] Power Bird Station Main Building 1A;

[0084] A tension training component is placed on the main body 1A of the power bird station, wherein the structure of the tension training component is as described in Example 1;

[0085] Pulling component 2A connects to one end of the pull wire 5 that is not connected to the movable pulley block 31, and is used to provide tension to the pull wire 5.

[0086] The structure of the resistance training component is the same as that described in Example 1, and will not be repeated here. The following will focus on the structure of the strength bird station in conjunction with the resistance training component.

[0087] Specifically, the main body 1A of the power training station includes a main frame 10A vertically arranged in the horizontal plane, a tension training component placed on the main frame 10A, and a flexible guide rail 32 fixed to the main frame 10A to form a vertically arranged sliding stroke area. In other words, the movable pulley group 31 makes vertical linear motion within the sliding stroke area. In some embodiments, a wall fixing structure is provided on the main frame 10A to fix the main frame 10A to a wall for use, which can minimize the footprint of the power training station.

[0088] Additionally, the main body 1A of the Power Bird Station includes a fixed pulley assembly 11A mounted on the main frame 10A. The fixed pulley assembly 11A is located on the side of the movable pulley assembly 31 away from the resistance motor 2, and is used to adjust the pulling direction of the pull cable 5. Correspondingly, the pull cable 5, which is wound around the movable pulley 312 mounted on the movable pulley assembly 31, is wound around the fixed pulley assembly 11A and then connected to the pulling member 2A.

[0089] In a specific embodiment, as shown in Figure 5, the fixed pulley group 11A of this solution includes a first high-position fixed pulley group 111A, a second high-position fixed pulley group 112A, and a low-position fixed pulley group 113A. The first high-position fixed pulley group 111A and the movable pulley group 31 are placed on the same vertical axis and located on the side of the movable pulley group 31 away from the resistance motor 2. The second high-position fixed pulley group 112A and the first high-position fixed pulley group 111A are located on the same horizontal axis. The first high-position fixed pulley group 111A is set at intervals, and the low-position fixed pulley group 113A and the second high-position fixed pulley group 112A are placed on the same vertical axis. The pull wire 5, which is placed on the movable pulley group 31, passes through the first high-position fixed pulley group 111A, the second high-position fixed pulley group 112A and the low-position fixed pulley group 113A in sequence before connecting to the pull-out member 2A. The setting of the fixed pulley group 11A can change the direction of the pulling force of the movable pulley group 31 in the sliding stroke area.

[0090] More specifically, the first high-position fixed pulley group 111A includes two first high-position fixed pulleys, the second high-position fixed pulley group 112A includes two second high-position fixed pulleys, and the low-position fixed pulley group 113A includes one low-position fixed pulley. One end of the pull wire 5, which is slidably fitted on the movable pulley group 1, passes through the corresponding first high-position fixed pulley, second high-position fixed pulley, and low-position fixed pulley and is connected to the puller 2A. The other end of the pull wire 5 passes through the corresponding first high-position fixed pulley, second high-position fixed pulley, and puller 2A and is connected to the puller 2A.

[0091] To accommodate the training needs of trainees at different heights, the main frame 10A is equipped with an adjusting rod 13A for adjusting the height of the pull member 2A. An adjusting sleeve 14A is fitted onto the adjusting rod 13A and slides onto it. The pull cable 3 passes through the adjusting sleeve 14A and connects to the pull member 2A. The advantage of this design is that the height of the pull member 2A can be adjusted to meet the pulling force training needs at different heights, and it can also be used to fix the pull member 2A.

[0092] Specifically, the adjusting rod 13A is provided with multiple adjusting holes, and the corresponding adjusting sleeve 14A is provided with a pull pin that matches the adjusting hole. When the adjusting sleeve 14A slides to a specific position, the adjusting sleeve 14A can be fixed by the cooperation of the pull pin and the adjusting hole, which can meet different movement actions such as high pull, low pull, foot pull, etc.

[0093] To facilitate the sliding of the adjusting sleeve 14A, pulley sets 15A are provided on both sides of the adjusting sleeve 14A. The pulleys on the pulley sets 15A slide relative to the adjusting rod 13A. In addition, the pulley sets 15A contain rotating bushings and are installed in a rotating shaft, so that the pulleys can rotate around the rotating shaft to meet the needs of the trainee for movement at different angles.

[0094] Example 3: Full-Function Electronic Dumbbell Bench

[0095] As shown in Embodiment 1 of this solution, the resistance training component suitable for strength training equipment can be used on a full-function electronic dumbbell bench. In this case, the strength training equipment is a full-function electronic dumbbell bench. Embodiment 3 provides an embodiment of a full-function electronic dumbbell bench, as shown in Figure 6. The full-function electronic dumbbell bench provided by this solution includes:

[0096] The pedal 1 has a standing area at the top, and at least one end of the standing area in the length direction has an extension mounting structure for installing extension functional components;

[0097] A tension training assembly as shown in Example 1, fixed to pedal 1;

[0098] The handle 6 is connected to the tension training component.

[0099] Specifically, one end of the standing area at the top of the pedal 1 is provided with an installation area, and the bottom of the pedal 1 is provided with a groove. The resistance motor 2 of the tension training component is set in the installation area, and the movable pulley group transmission structure 3 of the tension training component is set in the groove. The flexible guide rail 32 is set along the length direction of the pedal to form the sliding stroke area of ​​the movable pulley group 31. Correspondingly, the movable pulley group 31 moves back and forth along the sliding stroke area under the drive of the pull line 5 to realize the winding and unfolding of the resistance source pull rope.

[0100] Regarding the pedal 1 in this design, in order to further reduce the size of the pedal 1, the installation area is set at one end of the standing area. The advantage of this setting is that the resistance motor 2 can be installed at the top of the installation area, which can further reduce the volume of the electronic dumbbell bench.

[0101] In some embodiments, the bottom of the pedal 1 is a frame piece, which is assembled from multiple metal parts. The control panel 14 and the instrument 15 on the pedal 1 are prior art and will not be described in detail here. When in use, pressing the instrument 15 when the full-function electronic dumbbell bench is powered on will start the machine, rotating the instrument 15 will adjust the load weight, and pulling the front and rear handles 6 will allow you to perform various fitness movements.

[0102] To enable extended functionality, extension mounting structures 11 are provided at both ends of the standing area along its length for installing extended functional components. Figures 6 and 7 show two types of extension mounting structures 11, both designed to achieve installation of the extended components through simple structures, such as plug-in mechanisms and screw fixing, resulting in low operational and manufacturing difficulty. Other structural forms are not excluded and are not limited here. Alternatively, the extension holes 13 shown in Figures 6 and 7 could also be used.

[0103] As shown in Figure 8-10, the axes of the resistance motor 2 and the winding shaft 26 are both parallel to the length direction of the pedal 1. The resistance motor 2 includes a motor part 21 and a single-stage gear reducer 22 located at the output end of the motor part 21. The output end of the single-stage gear reducer 22 directly drives the winding shaft 26. Furthermore, for better heat dissipation, a cooling fan 27 is provided on one side of the resistance motor 2. Multiple ventilation holes 25 are provided on the end face of the resistance motor 2 facing the cooling fan 27, and multiple heat dissipation fins 24 are provided on the outer casing of the resistance motor 2. Compared to traditional planetary gear reducers, the single-stage gear reducer 22 has lower cost, higher transmission efficiency, lower maintenance costs, and higher reliability and stability under long-term operation.

[0104] Preferably, the resistance motor 2 serves as the resistance source, with its output directly driving the winding shaft 26 to rotate. The winding shaft 26 is positioned above the first fixed pulley 33, and its axial direction is perpendicular to the axial direction of the first fixed pulley 33 in the movable pulley transmission structure 3. The first fixed pulley 33 is located on one side below the winding shaft 26, ensuring that the resistance source rope 4 maintains a gap with the side of the central groove of the first fixed pulley 33 during winding or unwinding by the winding shaft 26. This prevents the resistance source rope 4 from contacting the side of the central groove of the first fixed pulley 33 during winding or unwinding, thus avoiding wear and tear on the resistance source rope 4. This not only prevents breakage due to wear but also improves the smoothness of use of the strength training equipment.

[0105] Preferably, the winding shaft 26 starts winding the resistance source rope 4 from the end closest to the resistance motor 2. The section of the resistance source rope 4 located between the first fixed pulley 33 and the winding shaft 26 is situated on the axial centerline of the first fixed pulley 33. When the winding shaft 26 winds the resistance source rope 4, the section of the resistance source rope 4 located between the first fixed pulley 33 and the winding shaft 26 changes from an inclined state towards the resistance motor 2 at the top to a vertical state, and then back to an inclined state towards the end away from the resistance motor 2 at the top. During the entire winding and unwinding process, the resistance source rope 4 located between the first fixed pulley 33 and the winding shaft 26 only switches between a vertical state and an inclined state. That is, if the two ends of the axial direction of the winding shaft 26 are taken as left and right, the resistance source rope 4 will only switch between tilting to the left, being vertical, and tilting to the right, and will not tilt in the axial direction of the first fixed pulley 33, that is, in the direction of the front and rear sides of the winding shaft 26.

[0106] Preferably, the winding shaft 26 is provided with retaining rings 261 at both ends of the axial direction. Each retaining ring 261 has a threading hole 262 on the side near the first fixed pulley 33 for fixing the resistance source pull rope 4. Each retaining ring 261 has two threading holes 262. The two threading holes 262 can hold the resistance source pull rope 4 in place, thereby distributing the force on the head of the resistance source pull rope 4 to the resistance source pull rope 4 between the two threading holes 262. This makes it less likely for the head of the resistance source pull rope 4 to be pulled off, resulting in a more stable effect.

[0107] In this embodiment, as shown in Figures 11-13, the movable pulley group transmission structure 3 includes: a movable pulley group 31, one end of which is connected to the resistance source pull rope 4, and the other end is connected to the pull line 5 through the movable pulley 312; a flexible guide rail 32, which is installed at the bottom of the pedal 1 and slides in cooperation with the movable pulley group 31 to allow the movable pulley group 31 to move back and forth along the length direction of the pedal 1; a first fixed pulley 33, which cooperates with the resistance source pull rope 4 and is used to convert the resistance source pull rope 4 from longitudinal to transverse; a second fixed pulley group 34, which cooperates with the pull line 5 and is used to convert one end of the pull line 5 from transverse to longitudinal; and a third fixed pulley group 35, which cooperates with the pull line 5 and is used to convert the remaining end of the pull line 5 from transverse to longitudinal.

[0108] Specifically, the second fixed pulley group 34 includes a first horizontal pulley 341 and a first longitudinal pulley 342. The pull cable 5 is connected to the first horizontal pulley 341 and the first longitudinal pulley 342 respectively, changing from being parallel to the length direction of the pedal 1 to being parallel to the height direction of the pedal 1. The third fixed pulley group 35 includes a second horizontal pulley 351 and a second longitudinal pulley 352. The pull cable 5 is connected to the second horizontal pulley 351 and the second longitudinal pulley 352 respectively, changing from being parallel to the length direction of the pedal 1 to being parallel to the height direction of the pedal 1. In this way, the structure of the movable pulley group 31 is significantly simplified. One pull cable 5 is connected to two movable pulleys 312 in sequence, instead of multiple turns of the cable to connect to two movable pulleys 312 separately. The structure is more stable and simpler, especially suitable for the narrower pedal 1.

[0109] One end of the resistance source pull rope 4 is wound around the winding shaft of the resistance motor 2, and the other end is connected to the movable pulley fixing block 311 through a first fixed pulley 33. The pull line 5 passes through the movable pulley 312, passes through the first horizontal pulley 341 and the first longitudinal pulley 342 and is connected to the rear handle 6. The other end of the pull line 5 passes around the rear second horizontal pulley 351 and then passes through the front second longitudinal pulley 352 and is connected to the front handle 6. Pulling the front handle 6 or the rear handle 6 (single or double pull, the principle is the same) causes the pull line 5 to rotate through two fixed pulley groups, pulling the movable pulley group. The movable pulley group 31 moves from front to back along the flexible guide rail 32. The resistance source pull rope 4 connected to the movable pulley group 31 is released from the winding shaft 26 of the resistance motor 2 under the action of the pulling force. After releasing the force on the front handle 6 or the rear handle 6, the winding shaft 26 of the resistance motor 2 rotates clockwise and winds the resistance source pull rope 4 onto the winding shaft 26 of the resistance motor 2. The resistance source pull rope 4 moves the movable pulley group 31 from back to front along the flexible guide rail 32 back to the initial state to form the winding (winding, winding, etc. all mean winding the resistance source pull rope 4 onto the winding shaft 26).

[0110] In this embodiment, one end of the pull cable 5 is detachably connected to a handle 6 via a pull cable connecting block 61, and the other end is detachably connected to another handle 6 via the pull cable connecting block 61. In this embodiment, the end of the pull cable 5 is mounted on the pull cable connecting block 61, which is provided with a pull ring 62. The pull ring 62 can be connected to the handle 6 using a common carabiner method, or other connection methods, which are not limited here, with the aim of achieving a quick-release function.

[0111] In some embodiments, the handle 6 is located at both ends or one end of the standing area along its length. In this embodiment, the handle 6 is prior art and is not limited here. It could also be a component with a similar function to the handle 6.

[0112] Example 4: Electronic dumbbell bench for bench press

[0113] Based on Embodiment 3, the pull training component suitable for strength training equipment shown in Embodiment 1 of this solution can be used on a bench press electronic dumbbell bench. In this case, the strength training equipment is a bench press electronic dumbbell bench. Embodiment 4 provides an embodiment of a bench press electronic dumbbell bench, as shown in Figures 14-16. The extended functional component of the bench press electronic dumbbell bench provided in this solution is a bench press accessory group 7, which includes:

[0114] The stool body 10 has a flat surface at the top for the user to lie down, and stool legs 102 at the bottom, which can be placed on the footboard 1 and supported on the ground by the stool legs 102;

[0115] The support rod 71 has an extension mounting structure 11 at the bottom that can be mounted on the pedal 1, and an adjustment bracket 72 at the top for holding dumbbell bars 73. The adjustment bracket 72 is telescopically engaged with the support rod 71 and locked by the adjustment and rotation component 74.

[0116] The dumbbell bar 73 has connectors 731 at both ends along its length.

[0117] The connecting wire 75 is detachably connected at one end to the connector 731 and detachably connected at the other end to the pull ring 62 of the pedal 1.

[0118] In this embodiment, the extended mounting structure 11 has a vertically arranged pipe opening as shown in Figure 6 or Figure 7. The pipe opening may have holes or threaded holes for mating with the connecting part 912 of the support frame 91 of this application. The style of the extended mounting structure 11 is not limited. The rowing machine accessory group 9 of this embodiment can expand the function of the electronic dumbbell bench of Embodiment 1. Preferably, the structure of the bench body 10 is not limited here; its main purpose is to provide a platform for the user to lie down, and it is best to avoid applying weight to the pedal 1, thereby reducing the burden on the pedal 1. The length of the bench body 10 is at least 80cm, and the width is at least 30cm. Of course, the bench body 10 can also be made of soft materials, such as genuine leather with sponge, silicone, or latex inside, and the outer surface can be made of artificial leather or other materials besides genuine leather; there are no limitations here. The bench legs 102 can adjust the height of the bench body 10 and increase friction with the ground.

[0119] In this embodiment, each support rod 71 has a tube and a mounting hole at its bottom. The tube is inserted into or outside the extension mounting structure 11 and secured with a threaded fastener in the mounting hole. Preferably, the tube is directly inserted into the pipe opening (extension mounting structure 11), and then the mounting hole is aligned with the hole on the side of the pipe opening and locked with a screw. Threads can be provided on the mounting hole or the hole on the side of the pipe opening. Preferably, both the support rod 71 and the adjusting bracket 72 are made of aluminum alloy, but they can also be made of high-strength plastic, as long as the strength is guaranteed.

[0120] Preferably, to facilitate height adjustment of the adjustable frame 72, each adjustable frame 72 or support rod 71 is provided with multiple adjustment holes. The height of the adjustable frame 72 is adjusted by cooperating with the positioning block and the adjusting rotating component 74. When the adjustable frame 72 is at its lowest height, the height of the dumbbell bar 73 is at least 30cm higher than the top of the bench 101. This ensures that the dumbbell bar 73 will not fall onto the user.

[0121] In this embodiment, the dumbbell bar 73 can be made of aluminum alloy, high-strength plastic, wood, etc., without limitation. The dumbbell bar 73 includes an inner tube 732, an outer tube 733, and end tubes 734 located at both ends of the outer tube 733. The connector 731, the outer tube 733, and the end tubes 734 are all installed outside the inner tube 732, and the connector 731 is located between the outer tube 733 and the end tubes 734. The connector 731 can be easily processed and installed on the dumbbell bar 73, and the distance between the two connectors 731 can be adjusted by changing the length of the outer tube 733. Especially when the connector 731 is damaged, only the end tubes 734 need to be removed to remove the connector 731 for replacement, resulting in low maintenance costs. More importantly, it can increase the overall strength of the dumbbell bar 73. That is, the inner tube 732 can be made of aluminum alloy, while the outer tube 733 and the end tubes 734 can be made of other decorative materials or materials with a better feel, thereby improving aesthetics and comfort.

[0122] Preferably, a limiting sleeve 735 is provided between the connector 731 and the outer tube 733, and between the connector 731 and the end tube 734. The limiting sleeve 735 limits the position of the connector 731 on the inner tube 732, preventing displacement without affecting the rotation of the connector 731, thus making the user's bench press smoother. Preferably, the length of the dumbbell bar 73 is more than 20cm greater than the distance between the two adjustment racks 72. This ensures that one end of the dumbbell bar 73 will not fall off the adjustment rack 72, ensuring that the dumbbell bar 73 can always be placed on both adjustment racks 72. Moreover, due to the connection line 75 and the connector 731, there is virtually no possibility that the dumbbell bar 73 will fall off the adjustment rack 72 due to displacement.

[0123] In this embodiment, fasteners 63 are provided at both ends of the connecting wire 75. The fasteners 63 are in the form of carabiners, which can easily connect the pull ring 62 and the connector 731. The connection is easy to install and remove, and is safe, stable and secure. The connector 731 is also provided with a pull ring 62 that cooperates with the fastener 63.

[0124] Example 5: High-Pull Electronic Dumbbell Bench

[0125] Based on Embodiment 3, the pull training component suitable for strength training equipment shown in Embodiment 1 of this solution can be used on a high-pull electronic dumbbell bench. In this case, the strength training equipment is a high-pull electronic dumbbell bench. Embodiment 5 provides an embodiment of a high-pull electronic dumbbell bench, as shown in Figures 17-20. The extended functional component of the bench press electronic dumbbell bench provided in this solution is a high-pull accessory group 8, which includes:

[0126] The extension base 81 is connected to the front or rear end of the pedal 1 of the electronic dumbbell bench in Embodiment 1;

[0127] The high-strength bracket 82 is fixedly connected to the extension base 81 at the bottom and has a fixed pulley 83 at the top;

[0128] The high-tension connecting line 84 is connected at one end to the pull line connecting block 61, and at the other end to the fixed pulley 83 and the pull rod 85.

[0129] The pull rod 85 is located above the pedal 1.

[0130] In this embodiment, the extended mounting structure 11 has a connection hole 811 on the inner side wall of the extended base 81, and an extension hole 13 corresponding to the connection hole 811 is provided on the front and / or rear side of the pedal 1. The connection hole 811 and the extension hole 13 are connected and fixed by threaded fasteners to fix the extended base 81 to the pedal 1. The extended base 81 can be fixed to the pedal 1 by connecting the front end to the rear side, without occupying space on the upper and lower surfaces of the pedal 1, and without affecting the use of the pedal 1. At the same time, disassembly and assembly are extremely convenient, without the need to lift or flip the pedal 1, significantly reducing the difficulty of operation. Of course, the connection method here is not limited to the above; it can also be a snap-fit ​​or plug-in operation, as long as there is sufficient connection strength.

[0131] The extension base 81 is equipped with multiple mounting structures 812 for mounting the high-tension bracket 82. These mounting structures 812 can be divided into parts for inserting and connecting the main rod 821 and parts for inserting the auxiliary rod 822. After insertion, they can be secured with screws, making operation convenient.

[0132] In this embodiment, the high-tension bracket 82 includes a main rod 821 and a plurality of auxiliary rods 822 connected to the main rod 821. The bottom of the main rod 821 and the bottom of the auxiliary rods 822 are detachably connected to the extension base 81 through the mounting structure 812. The main rod 821 is in the middle and the auxiliary rods 822 are on both sides, forming a triangle between the three.

[0133] Preferably, the top of the main rod 821 is curved and faces upwards towards the center of the pedal 1. This positions the pull rod 85 above or above the user's chest, allowing for easy access. Simultaneously, the main rod 821 cooperates with the auxiliary rod 822 so that when the user pulls downwards, the main load is concentrated on the auxiliary rod 822, reducing the burden on the main rod 821. Furthermore, the auxiliary rod's top bends towards the main rod 821, opposite to the main rod 821's bend direction, further increasing strength. Preferably, the curved portion at the top of the main rod 821 is a separate component, fixed to the top of the main rod 821 with screws. This reduces the manufacturing difficulty of the main rod 821 and facilitates subsequent packaging and transportation.

[0134] Preferably, both the main rod 821 and the auxiliary rod 822 can be made of aluminum alloy or stainless steel, although high-strength plastic with sufficient strength can also be used.

[0135] In this embodiment, the high-tension connecting cable 84 is connected to the cable connecting block 61 by a fastener 63, and the other end of the high-tension connecting cable 84 is connected to the cable connecting block 61. Preferably, the fastener 63 is a carabiner for easy operation. Each cable connecting block 61 is provided with a pull ring 62 for easy engagement with the fastener 63.

[0136] In this embodiment, the pull rod 85 is also connected to the pull cable connecting block 61 via the fastener 63, which facilitates operation.

[0137] The stool body 10 has a flat surface at the top for the user to lie down and stool legs 102 at the bottom. The stool legs 102 of the stool body 10 have plugs 101 that cooperate with the extension installation structure 11 to limit the position of the stool body 10 on the footboard 1.

[0138] In this embodiment, by placing the stool 10 on the pedal 1, it can be extended to operations such as pull-up exercises, expanding its application scenarios. The plug 101 connects the stool 10 to the pedal 1, preventing displacement of the stool 10, making it safer, more reliable, and simple to operate. Of course, the stool 10 can also be made of soft materials, such as genuine leather with sponge, silicone, or latex inside, and the outer surface can be made of artificial leather or other materials; there are no limitations here. The stool legs 102 can adjust the height of the stool 10 and increase friction with the pedal 1. The stool 10 is the same part as in Embodiment 2.

[0139] To achieve the mid-pull operation, as shown in Figure 14, a sliding assembly 813 is provided on the high-pull bracket 82. This sliding assembly 813 has a guide slider 86, which has a wiring hole 861 and a wire groove 862. The sliding assembly 813 has a notch 8131 corresponding to the wire groove 862. The sliding assembly 813 can move back and forth along the height direction of the high-pull bracket 82 and be fixed. The high-pull bracket 82 has multiple positioning holes. The sliding assembly 813 is adjusted in height by engaging with the positioning holes via a pull pin 863. The high-pull connecting wire 84 is removed from the fixed pulley 83 and the wire connecting block 61. The wire 5 is then inserted from the notch 8131 and the wire groove 862 into the wiring hole 861 of the guide slider 86, and then connected to the pull rod 85 via the wire connecting block 61. At this point, the high-pull action is no longer performed. After adjusting the height position of the sliding assembly 813, the mid-pull movement is achieved.

[0140] Preferably, the guide slider 86 is rotatably connected to the sliding assembly 813. After the pull wire 5 enters the wiring hole 861 of the sliding assembly 813 through the notch 8131 and the wire groove 862, simply rotating the guide slider 86 misaligns the notch 8131 and the wire groove 862, thus preventing the pull wire 5 from coming out and ensuring greater safety and reliability. Alternatively, the notch 8131 and the wire groove 862 can be positioned at the end or side away from the pull rod 85. This way, when the user operates the pull rod 85, the pull wire 5 is close to the end of the wire groove 861 closest to the user and will not come out of the notch 8131 and the wire groove 862.

[0141] Example 6: Rowing Machine

[0142] Based on Embodiment 3, the pull training component suitable for strength training equipment shown in Embodiment 1 of this solution can be used on a rowing machine. In this case, the strength training equipment is a rowing machine. Embodiment 6 provides an embodiment of a rowing machine, as shown in Figures 21-23. The extended functional component of the bench press electronic dumbbell bench provided in this solution is rowing machine accessory group 9, which includes:

[0143] The support frame 91 has a connecting part 912 at the bottom for connecting the pedal 1, and a pull rod 85 and a mounting seat 911 for mounting the guide slider 86 at the top;

[0144] The guide slider 86 is mounted on the mounting base 911 and has a cable hole 861 through which the cable 5 of the electronic dumbbell bench passes. The edge of the cable hole 861 has a cable groove 862 for the cable 5 to enter.

[0145] The foot pedal 931 is movably connected to the support frame 91 at one end and has a mounting groove 933 for mounting the slide rail 94 at the other end.

[0146] The slide rail 94 has one end bottom that mates with the mounting groove 933, and the other end bottom that can be supported on the ground by the bottom bracket 942, forming a track for the stool 95 to move.

[0147] The stool 95 is mounted on the slide rail 94 and can move back and forth along the length of the slide rail 94.

[0148] In this embodiment, the extended mounting structure 11 has a vertically arranged pipe opening as shown in Figure 1. The pipe opening may have holes or threaded holes for mating with the connecting part 912 of the support frame 91 of this application. Two types of extended mounting structures 11 are shown in Figure 1, and no limitation is made here. The rowing machine accessory group 9 of this embodiment can expand the functionality of the electronic dumbbell bench of Embodiment 1. The pull rod 85 of this embodiment is the same part as the pull rod 85 of Embodiment 3.

[0149] Preferably, the connecting part 912 has one or more positioning holes on its side wall. When there is only one positioning hole, the connecting part 912 can be installed on the footplate 1 of the electronic dumbbell bench using threaded fasteners or the like. When there are multiple positioning holes, the height of the support frame 91 can be adjusted by selecting different positioning holes. That is, in this embodiment, the connecting part 912 of this application is a tubular structure, which is inserted into or outside the tube opening of the electronic dumbbell bench and fixed by screws or knobs passing through the positioning holes.

[0150] The positioning hole can be a through hole without threads, while a threaded hole can be provided on the tube opening (extension mounting structure 11) of the electronic dumbbell bench, allowing the connecting part 912 and the tube opening to be fixed with screws or other threaded fasteners. Alternatively, the positioning hole can be threaded, eliminating the need for threads on the tube opening. Preferably, the support frame 91 can be a gate-shaped or T-shaped structure, etc., without limitation.

[0151] The guide slider 86 is horizontally embedded in the mounting base 911. The pull cable 5 is connected to the pull rod 85 through the pull cable connecting block 61, and the pull rod 85 and the pull cable connecting block 61 are movably connected. The pull cable 5 can be directly inserted into the cable hole 861 through the cable groove 862. The pull rod 85 has a through hole, and the pull ring 62 on the pull cable connecting block 61 (this pull ring 62 is detachable and fixed by means of pins, bolts, and buckles) was originally connected to the handle 6 by a carabiner. Here, it can be directly threaded through the through hole, thus quickly connecting to the pull rod 85. Of course, it is preferable that the pull rod 85 originally has a pull ring 62. The original pull ring 62 on the pull cable connecting block 61 is removed, and the pull ring 62 on the pull rod 85 is installed, which can quickly complete the installation. When disassembling, the pull ring 62 can be replaced, which can achieve quick disassembly and higher disassembly and assembly efficiency. Furthermore, the cable connector 61, being an integral part of the original electronic dumbbell bench, is located between the handle 6 and the guide slider 86. This prevents the handle 6 from directly impacting the guide slider 86 due to the retraction force of the cable 5, thus preventing injury to the user. The same effect is achieved when used on the pull rod 85, making it even safer and more reliable. The guide slider 86 here has the same structure as the guide slider 86 in Embodiment 3; they are the same type of part, differing only in their installation position.

[0152] Preferably, the guide slider 86 of the original electronic dumbbell bench has a structure and principle that are basically the same as the guide slider 86 of this application. The difference is that the guide slider 86 of this application has a wire groove 862, while the guide slider 86 of the original electronic dumbbell bench does not need to be disassembled when using this application. Furthermore, in order to prevent jamming, a chamfer or rounded corner is provided at the edge of the opening of the guide slider 86, that is, the use of a smooth transition surface can significantly reduce the occurrence of jamming.

[0153] In this embodiment, the support frame 91 has a connecting seat 913 on its side that mates with the foot pedal 931. The foot pedal 931 is rotatably connected to the support frame 91 via the connecting seat 913. The foot pedal 931 includes a connecting frame 931 movably connected to the support frame 91 and a pedal portion 932 on the connecting frame 931. The pedal portion 932 has a mounting groove 933, and the bottom of the slide rail 94 facing the foot pedal 931 has a mounting portion 941 that mates with the mounting groove 933. The connecting seat 913 allows for easy installation of the foot pedal 931, enabling rotation and quick assembly / disassembly. Alternatively, the foot pedal 931 can be fixed to the support frame 91 via the connecting seat 913 (without affecting its rotation), reducing subsequent assembly / disassembly steps.

[0154] In this embodiment, the mounting part 941 is rotatably connected to the slide rail 94. The angle between the slide rail 94 and the ground or the pedal 1 of the electronic dumbbell bench can be adjusted by adjusting the angle between the mounting part 941 and the slide rail 94.

[0155] Preferably, the slide rail 94 is provided with a movably connected clamping bracket 943, which is used to clamp mobile devices. The main purpose of the clamping bracket 943 is to mount mobile devices such as mobile phones or tablets, allowing users to train while exercising using an app on the mobile device. Alternatively, the mobile device can wirelessly connect to an electronic dumbbell bench, allowing users to adjust resistance and perform other operations via the app. Preferably, the clamping bracket 943 operates on the same principle as existing mobile phone or tablet holders, allowing for multi-angle adjustment and rotation. It can be fixed to the slide rail 94 and not detachable, or it can be detachable from the slide rail 94; this is not limited here.

[0156] Preferably, the bottom bracket 942 is fixed to the slide rail 94 with screws, so it can be disassembled. There is also a support foot 9421 under the bottom bracket 942, which can adjust the height and provide a good anti-slip effect.

[0157] In this embodiment, the bottom of the stool 95 is provided with a guide portion 951, which has a notch 8131 that mates with the slide rail 94. A pulley 952 that mates with the slide rail 94 is located within the notch 8131. The slide rail 94 has multiple adjustment holes 944, and the stool 95 has an adjustment switch 953 that mates with each adjustment hole 944. By inserting the adjustment switch 953 into the corresponding adjustment hole 944, the stool 95 can be locked onto the slide rail 94, thus enabling individual stretching strength training. Preferably, the adjustment switch 953 can be a rotary telescopic type, meaning it moves in and out of the adjustment hole 944 by rotating, or it can be a press type, meaning it moves in and out of the adjustment hole 944 by pressing; neither is limited here.

[0158] Preferably, the comfort of the seat 95 can be improved by using flexible materials such as silicone, sponge, and latex.

[0159] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0160] This invention is not limited to the preferred embodiments described above. Anyone can derive other products in various forms under the guidance of this invention. However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
