Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fitness equipment, in particular to fitness equipment with a resistance multiplying structure. Background Art
[0002] At present, with the improvement of people's living standards and the promotion of national fitness, people's pursuit of healthy life is also increasing, and fitness has become an indispensable part of people's daily life. In addition, with the change of fitness concepts, more and more people go to the gym to use special fitness equipment to exercise.
[0003] In a gym, you usually need to use special fitness equipment according to the body parts and exercises you want to exercise, such as Smith machines, seated rowing machines, leg press machines, fly machines, T-pulldown machines, barbell training racks, etc. These fitness equipment usually need to occupy a large area, which is not a burden for large gyms, but is difficult to enter ordinary households.
[0004] In response to this, in order to cater to ordinary families, fitness equipment that uses motors to generate training impedance has appeared on the market at this stage. These fitness equipment replaces traditional physical weight blocks such as barbell plates with digitally controlled resistance. For example, multiple units in the field of traditional equipment can be designed as a swing arm structure to replace them. It can achieve multiple functions in a compact structure, reduce the size of the equipment, and meet people's regular training programs, making it possible for dedicated fitness equipment to enter ordinary families in daily life. Utility Model Content
[0005] Issues to be Solved by Utility Models
[0006] For this kind of fitness equipment that controls resistance digitally, the maximum resistance (pulling force) it can generate is proportional to the output torque of the motor. The greater the output torque of the motor, the greater the maximum resistance (pulling force) the fitness equipment can generate. For strength training equipment, the maximum resistance (pulling force) it can generate determines the user experience to a certain extent, especially for low-position training movements such as deadlifts, squats, bench presses, etc., which usually require the motor to generate a sufficiently large output torque to meet the training resistance of these heavy weight training.
[0007] However, if the resistance requirement of the equipment is to be met by directly increasing the output torque of the motor, the cost and quantity of the motor must be increased. Moreover, not only the cost and quantity of the motor will increase, but also other indirect costs such as structural enhancement and increased driving current will increase accordingly. In addition, the structure of the fitness equipment will become more complicated, resulting in an increase in the overall volume.
[0008] In addition, in strength training, the heaviest movements are generally low-position training movements such as deadlifts and squats. The maximum weight of such movements is generally more than 1.5 times the weight required for most other movements. Although low-position training movements require the heaviest weight, other training movements do not require heavy weights. The motor output of this type of fitness equipment that digitally controls resistance can basically meet the needs of ordinary training. If the output torque of the motor is simply increased just for the needs of low-position training movements, resulting in increased costs, the fitness equipment may not be accepted by ordinary consumers due to excessive costs.
[0009] In addition, sometimes, in order to simplify the overall structure of fitness equipment, a solution is proposed to reduce the number of motors and use only one motor. In this case, if a single motor is needed to perform heavy deadlifts and squats, the output torque of the single motor needs to be further increased, which will lead to a further increase in the cost of the motor and even make it impossible to implement a single motor structure, thereby making it impossible to simplify the overall structure of the fitness equipment.

[0073] Below, Figures 1 to 10 The fitness equipment shown in the figure is taken as an example to illustrate the fitness equipment with resistance multiplying structure of the present invention.
[0074] Figure 1 This is a front perspective view of a fitness device with a resistance multiplying structure in one embodiment of the utility model in a use state; Figure 2 This is a front view of a fitness device with a resistance multiplier structure in one embodiment of the utility model in a use state with some components omitted; Figure 3 It is a perspective view of a fitness device with a resistance multiplying structure in one embodiment of the utility model in a use state with some components omitted; Figure 4 This is a perspective view of a fitness device with a resistance multiplier structure in a storage state with some components omitted. Figure 1 to Figure 3 It is a schematic diagram showing the state of use. Figure 4 It is a schematic diagram in the storage state. Here, the so-called use state refers to, for example, when a swing arm (described later) is provided, the swing arm is in an extended state, and the so-called storage state refers to, for example, when a swing arm (described later) is provided, the swing arm is located on both sides of the main body (described later). In addition, the so-called use state sometimes refers to, for example, when a rack (described later) is provided, the rack is in an unfolded state, and the so-called storage state refers to, for example, when a rack (described later) is provided, the rack is in a folded state. In addition, for the sake of convenience of explanation, the side facing the reader is sometimes referred to as the front side ( Figure 1 Roughly to the right of center, Figure 2 The side opposite to the front side is the back side ( Figure 1 Roughly to the left of center, Figure 2 side of the drawing facing away from the reader).
[0075] like Figure 1 to Figure 4 As shown, in a specific embodiment of the present utility model, the fitness equipment H mainly includes: a main body 1; a motor 2 (specifically, see Figure 3 and Figure 4 , Figure 1 The winding drum 3 connected to the motor 2 (refer to Figure 3 and Figure 4 , Figure 1 for the user to hold during training 4 (specific reference Figure 1 ); relative to the removable training accessories 5 of the fitness equipment (specific reference Figure 1 ); and rope R.
[0076] In a specific embodiment of the present invention, Figure 3 and Figure 4 As shown, the motor 2 and the winding drum 3 are both arranged on the back of the main body 1, one end of the rope R is directly fixed to the winding drum 3 so that the rope R can be wound around the winding drum 3, and the rope R can be guided by a component such as a pulley or a pulley group or a swing arm (described later) so that the other end of the rope R is guided to the outside of the main body 1. In the present utility model, the other end of the rope R guided to the outside of the main body 1 is referred to as the "free end of the rope R". In addition, the motor 2 and the winding drum 3 can also be directly arranged inside the main body 1 as needed, and there is no special limitation on this.
[0077] In addition, in a specific embodiment of the present invention, Figure 3 and Figure 4 As shown, a structure in which two motors 2 are used and a winding drum 3 is installed on each motor 2 and a rope R is wound on each winding drum 3, but the utility model is not limited thereto. Considering the overall volume and compactness of the fitness equipment, it is also possible to design the internal pulley or pulley group of the main body and use only one motor to convert the single-end rope output of the single motor into a double-end rope output at the output end (such as the swing arm end, the free end of the rope) (for example, refer to the later described Fig.14 and Fig.15 In the present invention, for the sake of convenience, the following description takes the case where the fitness equipment has two motors, each motor is equipped with a winding disk, and one end of the rope R is directly fixedly connected to the winding disk as an example, but the present invention is not limited to this.
[0078] Specifically, in one embodiment of the present invention, Figure 1 to Figure 4 As shown, one end of the rope R is fixed to the winding drum 3 so that it can be wound on the winding drum 3, and the other end of the rope R is a free end Rf. The free end Rf of the rope R extends from the inside of the main body 2 and is detachable relative to the training accessory 5.
[0079] In a specific embodiment, an accessory connector Rc is provided at the free end Rf of the rope R, and a rope connector 51 that can be connected to the accessory connector Rc is provided on the training accessory 5 (carrying plate). By connecting the accessory connector Rc with the rope connector 51, the free end Rf of the rope R can be fixedly mounted on the carrying plate as the training accessory 5. The connection method between the accessory connector Rc and the rope connector 51 can be a threaded connection, a snap-on structure, or a hooking structure, and under certain conditions, it can also be set to other connection methods such as magnetic attraction connection.
[0080] In addition, if Figure 1 As shown, in a more specific embodiment of the present invention, the main body 1 is a vertically arranged plate-shaped component, and the training accessory 5 is a plate-shaped component that is independent of the main body 1 and horizontally arranged. More specifically, the training accessory 5 can be set as a horizontally placed loading plate, and the training accessory 5 and the main body 1 are in a relatively vertical spatial position relationship (the plane where the training accessory 5 is located is relatively vertical to the plane where the main body 1 is located).
[0081] In addition, in the present invention, the grip 4 is further provided with a sliding fitting 6. When the free end Rf of the rope R is fixedly mounted on the training accessory 5, the sliding fitting 6 of the grip 4 can be hung on the rope R and relatively slide along the rope R. More specifically, when the free end Rf of the rope R is mounted on the training accessory 5, the sliding fitting 6 of the grip 4 is hung on the rope R. At this time, the rope R is tensioned by the user pulling the grip 4, and the sliding fitting 6 can slide relatively on the rope R by further pulling the grip 4 back and forth. By making such an arrangement, the device can be operated more smoothly with a simple structure.
[0082] In one embodiment of the present invention, Figure 1 As shown, the gripping member 4 is specifically a gripping rod, and the sliding fitting member 6 includes a pulley 61. A sliding fitting member 6 is respectively provided at both ends of the gripping rod as the gripping member 4, wherein the pulley 61 of the sliding fitting member 6 is fixed to both ends of the gripping rod as the gripping member 4 through an axis. Figure 1 As shown, when the free end Rf of the rope R is fixedly mounted on the training accessory 5, the pulley 61 can be hung on the rope R (as an example, the slide groove of the pulley 61 is hung on the rope R), so that the pulley 61 can slide relatively along the rope R, thereby allowing the gripping rod serving as the gripping member 4 to slide relatively along the rope R.
[0083] In addition, in a specific embodiment of the present invention, Figure 1 to Figure 4 As shown, the main body 1 is also provided with a swing arm (or swing arm assembly) 7 through which a rope R can pass. When the rope R passes through the inside of the swing arm 7, the free end Rf of the rope R extends from the front end of the swing arm 7 so that it can be further fixed to the training accessory 5. Here, the swing arm (swing arm assembly) 7 can be moved up and down and rotated in various directions by means of structures such as guide rails, sliders, and rotating shafts, but this is not limited and can also be in other forms. In addition, a pulley or pulley group structure can also be provided inside the main body 1 (for example, refer to Figure 3 , Figure 4 ) or a guide mechanism etc. guides the rope R from the winding drum 3 on which it is wound to the swing arm 7 and passes through the inside of the swing arm 7 and extends from the front end of the swing arm 7, and is further installed on the training accessory 5 by combining the accessory connector Rc of the free end Rf of the rope R with the rope connector 51 of the training accessory 5, which will not be described in detail here. In addition, it is also possible to Fig.14 , Fig.15 As shown, only one motor is used to connect the rope R indirectly to the winding drum via a pulley / pulley block combination (for example, a pulley block and a pulley frame, etc.) provided inside the main body, and the output resistance (tension) generated by the motor is transmitted to the rope R through the rope wound on the winding drum (such as the resistance output side wire described later) and the pulley / pulley block / pulley frame combination provided inside the main body.
[0084] In the above-mentioned Figure 1 to Figure 4 In the embodiment shown, assuming that the output resistance of the motor 2 is F, the force on the rope R is F. If the user directly pulls the free end Rf of the rope R (or pulls the rope R via a handle component (described later)), the pulling force required by the user is the same as the output resistance of the motor, both of which are F. However, in this embodiment, the free end Rf of the rope R can be fixedly mounted on the training accessory 5. When the free end Rf of the rope R has been fixedly mounted on the training accessory 5, the sliding fitting 6 of the grip 4 is hung on the rope R so that it can slide relatively along the rope R. If the user pulls the grip 4 to make the rope R in a tensioned state, according to the movable pulley principle, the force on the grip 4 is twice the force on the rope R, that is, the output resistance F, which is 2F. Compared with when the user directly pulls the rope R, the output resistance can be doubled.
[0085] More specifically, if Figure 1As shown, when the free end Rf of the rope R has been fixedly installed on the training accessory 5, the accessory connector Rc of the free end Rf of the rope R is combined with the rope connector 51 of the training accessory 5 and installed on the training accessory 5, and the slide groove of the pulley 61 of the sliding matching member 6 of the grip 4 is hung on the rope R, so that when the user pulls the grip 4 to tighten the rope R, the slide groove of the pulley 61 can slide along the rope R. According to the principle of the movable pulley, when the user pulls the grip rod as the grip 4, the force of the grip 4 located on the movable pulley is twice the force of the rope R. That is, according to the utility model, the double motor output resistance can be obtained only by a simple structure, so that the increase of the output resistance can be achieved at a low cost.
[0086] Next, refer to Figures 5 to 8 , a fitness device with a resistance multiplication structure according to another embodiment of the utility model is described. Figure 5 It is a front stereoscopic view of a fitness device with a resistance multiplying structure in another embodiment of the utility model in a use state (expanded state);
[0087] Figure 6 It is a front perspective view of a fitness device with a resistance multiplying structure in another embodiment of the utility model in a use state (expanded state) with some components omitted; Figure 7 It is a front perspective view of a fitness device with a resistance multiplying structure in another embodiment of the utility model in a use state (expanded state) with some components omitted; Figure 8 It is a front stereoscopic view of a fitness device with a resistance multiplying structure according to another embodiment of the utility model in a stored state (folded state).
[0088] In the fitness equipment H with resistance multiplication structure of this embodiment, in addition to the above structure, Figures 5 to 8 As shown, the fitness equipment H further comprises a frame 8 rotatably connected to the main body 1 .
[0089] Specifically, if Figures 5 to 8 As shown, a frame 8 is rotatably connected to the bottom of the vertically arranged main body 1. The frame 8 can be switched between a folded state and an unfolded state. In a specific embodiment, the main body 1 is vertically arranged (for example, perpendicular to a horizontal plane or a bottom plane), and at the bottom of the main body 1, the frame 8 is rotatably connected to the main body 1 through a rotating shaft or a hinge. When the frame 8 is rotated to a state parallel to the main body 1 (for example, as shown in FIG. 1 ), the frame 8 can be switched between a folded state and an unfolded state. Figure 8 As shown in FIG. 1 , the frame 8 and the main body 1 are both in a vertical state (perpendicular to the bottom surface or horizontal plane) at this time, and this state is referred to as a "folded state (sometimes also referred to as a "storage state" of the fitness equipment H)"; when the frame 8 is rotated to a state perpendicular to the main body 1 (for example, Figure 5 As shown in the figure, the frame 8 is placed horizontally on the ground), and this state is called the "unfolded state" (sometimes this state is also called the "working state" or "use state" of the fitness equipment H). Here, terms such as "vertical" and "parallel" do not strictly refer to absolute verticality and parallelism in a geometric sense, and can also be a state slightly offset by a certain angle, as long as it is roughly vertical or horizontal.
[0090] In addition, in another embodiment of the utility model, the frame 8 can be switched between a folded state and an unfolded state intersecting with the main body 1. In this other embodiment, the unfolded state is the same as the above embodiment, and the cross-folded state means that the side of the vertically placed frame 8 in the storage state is intersecting with the main body instead of being parallel or overlapping, which will not be described in detail.
[0091] In addition, if Figure 5 to Figure 7 As shown, when the frame 8 is in the unfolded state (the fitness equipment H is in the working state), a loading board for users to use can also be horizontally laid on the frame 8. At this time, the loading board can be used as a training accessory 5. By laying the loading board (training accessory 5) horizontally, the user can, for example, stand on the loading board to train or perform other activities. In this embodiment, the loading board as the training accessory 5 can be composed of a whole piece of material (integral structure) or multiple pieces of material (split structure). In addition, there is no limitation on the material of the loading board, and there is no limitation on the type of loading board, and various design changes can be made to the loading board according to needs. As a result, various accessories can be replaced according to the type of training and the needs of the user, so that the freedom of use is improved.
[0092] In addition, in this embodiment, the frame 8 also includes an outer frame 81 that is roughly in the shape of a Japanese Kana character U (or U-shape) and is rotatably connected to the main body 1 and is arranged around the loading plate when the loading plate (training accessory 5) is placed horizontally. The loading plate (training accessory 5) is removable relative to the outer frame 81.
[0093] In addition, if Figure 6 to Figure 8 As shown, the outer frame 81 is further provided with a guide slide 82, and the rope R can be fixedly mounted on the mounting plate (training accessory 5) after passing through the swing arm 7 through the guidance of the guide slide 82. As an example of the guide slide, for example, a guide pulley, a guide with a slide groove, etc. can be cited, and the guide pulley is taken as an example for explanation in the present invention.
[0094] In addition, in this embodiment, Figure 6 to Figure 8 As shown, a rope connector 51 may be provided on the outer frame 81 to replace the rope connector provided on the mounting plate serving as the training accessory 5, thereby enabling the surface of the mounting plate serving as the training accessory 5 to be simple and flat, and to be well stored even when not in use.
[0095] In a specific embodiment of the present invention, Figure 5 As shown, the gripping member 4 is two handles (pulling rings), and each handle is provided with a sliding fitting 6. In addition, in this embodiment, Figure 5 As shown, the sliding fitting 6 is composed of a pulley 61 and a pulley bracket 62. The pulley bracket 62 is fixed to the handle serving as the holding member 6. The pulley 61 is installed on the pulley bracket 62 in an axially supported manner, for example, by a bearing provided on the pulley bracket 62. The pulley 61 can also be directly installed on the pulley bracket 62 using an axis.
[0096] In this embodiment, Figure 1 to Figure 4 The embodiment shown is the same, assuming that the output resistance of the motor 2 is F, then the force on the rope R is F at this time. If the user directly pulls the free end Rf of the rope R (or pulls the rope R via the handle component (described later)), the pulling force required by the user is the same as the output resistance of the motor, both of which are F. However, in this embodiment, the free end Rf of the rope R can be fixedly installed on the training accessory 5 (loading plate). When the free end Rf of the rope R has been fixedly installed on the training accessory 5, the sliding fitting 6 on the handle of the grip 4 is hung on the rope R so that it can slide relatively along the rope R. If the user pulls the grip 4 to make the rope R in a tensioned state, then according to the movable pulley principle, the force on the grip 4 is twice the force on the rope R, that is, the output resistance F, which is 2F. Compared with when the user directly pulls the rope R, the output resistance can be doubled.
[0097] More specifically, if Figure 5 As shown, the rope R is guided by the guide slide 82 and the accessory connector Rc of the free end Rf thereof is fixedly mounted on the outer frame 81 by combining with the rope connector 51 of the outer frame 81, and the slide groove of the pulley 61 of the sliding fitting 6 of the grip 4 is hung on the rope R. When the user pulls the grip 4 to make the rope R in a tensioned state, the pulley 61 can slide relatively along the rope R as a movable pulley. According to the force analysis of the movable pulley, when the user pulls the handle as the grip 4, the force on the handle (grip 4) on the movable pulley is twice the force on the rope R. In other words, according to the utility model, the double motor output resistance can be obtained only by a simple structure, so that the increase of output resistance can be achieved at a low cost.
[0098] In addition, in this embodiment, Figures 5 to 8 As shown, a swing arm (or swing arm assembly) 7 through which a rope R can pass may also be provided. When the rope R passes through the inside of the swing arm 7, the free end Rf of the rope R extends from the front end of the swing arm 7 so that it can be further fixedly installed on the training accessory 5.
[0099] In addition, in this embodiment, after the free end Rf of the rope R extends from the front end of the swing arm 7, it is first guided by the guide slider 82, and then fixed to the rope connector 51 to be fixedly connected to the outer frame 1 or the mounting plate of the training accessory 5. Therefore, compared with the case where the free end Rf of the rope R is not guided by the guide slider 82, the resistance output can be further smoothed and stabilized, and the rope can be kept stable and not easy to fall out during the training process, so that more complex training items with greater resistance can be handled.
[0100] In addition, if Fig.14 and Fig.15 As shown, in another embodiment, considering the volume and compactness of the entire fitness equipment and the advantage of greatly reduced costs brought by a single motor, only one motor 2 may be used, and a winding drum 3 may be installed on the motor 2. By making design changes to the pulley or pulley group inside the main body 1, the single-end rope output of the single motor can be converted into a double-end rope output at the output end (e.g., the swing arm end).
[0101] For example, refer to Fig.14 In one example, the fitness equipment further includes a first pulley block PB1 having one or more pulleys (pulleys P1, P2, P3), a second pulley block PB2 having one or more pulleys (pulleys P4, P5, P6, P7, P8, P9), and a pulley frame C connecting the first pulley block PB1 and the second pulley block PB2. In other words, the pulley frame C serves as a common pulley frame of the first pulley block PB1 and the second pulley block PB2 to connect the two together. In a specific example, as Fig.14 As shown, the pulley P3 of the first pulley block PB1 is arranged on the pulley frame C, and the pulley P7 of the second pulley block PB2 is arranged on the same pulley frame C, so that the first pulley block PB1 and the second pulley block PB2 can be connected together via the pulley frame C.
[0102] In addition, in the present embodiment, the fitness equipment has only one motor 2, on which a winding drum 3 is mounted, and one end of the resistance output side wire S (the wire that outputs the resistance generated by the motor 2) is fixed to the winding drum 3 and can be wound around the winding drum 3. In addition, the resistance output side wire S is sequentially wound around pulleys P1, P2, and P3 (first pulley group PB1) starting from the motor 2, and the other end thereof is fixed to the fitness equipment (for example, fixed to the housing or other parts of the main body 1). Both ends of the rope R are free ends of the rope (as mentioned above, the free ends of the rope can be connected to training accessories or grips, etc. through connecting components), and the rope R is sequentially wound around pulleys P4, P5, P6, P7, P8, and P9 (second pulley group PB2). In addition, as mentioned above, by connecting the pulley P3 of the first pulley group PB1 and the pulley P7 of the second pulley group PB2 via a common pulley frame C, the first pulley group PB1 and the second pulley group PB2 can be connected together. In other words, the pulley frame C is used as a common pulley frame for the first pulley block PB1 and the second pulley block PB2, and the rope R can be associated with the output of the motor 2 by connecting the first pulley block PB1 and the second pulley block PB2 to the pulley frame C. In the present embodiment, the pulley P3 and the pulley P7 are set as movable pulleys, and the other pulleys are set as fixed pulleys, but the present invention is not limited to this.
[0103] In another example, refer to Fig.15 The fitness equipment also includes a first pulley block PB1 having one or more pulleys (pulleys P1, P2, P3, P4, P5, P6, P7), a second pulley block PB2 having one or more pulleys (pulleys P8, P9, P10, P11, P12, P13, P14, P15, P16), and a pulley frame C connecting the first pulley block PB1 and the second pulley block PB2. In other words, the pulley frame C serves as a common pulley frame of the first pulley block PB1 and the second pulley block PB2 to connect the two together. In a specific example, as Fig.15 As shown, the pulleys P3, P5, and P7 of the first pulley block PB1 are arranged on a pulley frame C, and the pulleys P10, P12, and P14 of the second pulley block PB2 are arranged on the same pulley frame C, so that the first pulley block PB1 and the second pulley block PB2 can be connected together via the pulley frame C.
[0104] In addition, Fig.15In the example shown, the fitness device also has a motor 2, on which a winding drum 3 is mounted, and one end of the resistance output side wire S is fixed to the winding drum 3 so that it can be wound around the winding drum 3. In addition, the resistance output side wire S is sequentially wound around pulleys P1, P2, P3, P4, P5, P6, and P7 (first pulley group PB1) starting from the motor 2, and the other end is fixed to the fitness device (for example, fixed to the housing or other parts of the main body 1). Both ends of the rope R are free ends of the rope, and the rope R is sequentially wound around pulleys P8, P9, P10, P11, P12, P13, P14, P15, and P16 (second pulley group PB2). Furthermore, the pulleys P3, P5, and P7 of the first pulley block PB1 and the pulleys P10, P12, and P14 of the second pulley block PB2 are connected together through the pulley frame C, thereby connecting the first pulley block PB1 and the second pulley block PB2 together. In other words, the pulley frame C is used as a common pulley frame for the first pulley block PB1 and the second pulley block PB2, and the rope R can be associated with the output of the motor 2 through the connection between the first pulley block PB1 and the second pulley block PB2 and the pulley frame C. In this embodiment, the pulleys P3, P5, and P7 of the first pulley block PB1 and the pulleys P10, P12, and P14 of the second pulley block PB2 are set as movable pulleys, and the other pulleys are set as fixed pulleys, but the present invention is not limited to this.
[0105] In the above-mentioned embodiments using a single motor, for example, when the free end of the rope R is pulled, the pulling force is transmitted through the first pulley group PB1, the second pulley group PB2 and the pulley frame C to pull the resistance output side wire S on the winding drum 3 on the motor 2 side, so that the resistance output side wire S is pulled out of the winding drum 3 or has a tendency to be pulled out of the winding drum 3 (wire output). When the tension on the free end of the rope R is weakened or the output of the motor 2 is increased, according to the connection relationship of the above-mentioned pulley group, the resistance output side wire S is wound into the winding drum 3 through the motor or has a tendency to be wound into the winding drum 3 (wire reeling). Thus, the single-end wire output of the single motor is converted into a double-end wire output at the output end (such as the swing arm end) by designing the pulley or pulley group inside the main body 1.
[0106] By adopting a single motor in the fitness equipment of the utility model, the cost can be further reduced and the miniaturization of the device can be further achieved. In particular, the utility model can double the output resistance by improving the structure. Therefore, even in the case of a single motor, it is possible to cope with low-position training movements such as heavy deadlifts and squats with a simple structure without increasing the number of motors and costs, and the overall structure of the equipment can be further simplified.
[0107] In addition, in the above-mentioned embodiment, the example in which both ends of the rope R are free ends is used for explanation, but it is also possible to use a single motor and two ropes by changing the design of the connection relationship between the pulley, the pulley block and the rope. In this case, the output resistance on both sides of the swing arm part can be fed back for control.
[0108] In yet another embodiment of the present invention, Fig. 9 and Fig.10 As shown, the difference from the above embodiment is that the main body 1 is a horizontally arranged plate-shaped component, and the loading plate for the training accessory 5 is horizontally arranged on the upper surface of the main body 1. In addition, the upper surface of the main body 1 can also be directly used as the surface of the training accessory 5 according to the situation, that is, the main body 1 and the training accessory 5 can be formed into one. In this case, the training accessory 5 can be arranged on the surface of the main body 1 by snap-fitting, magnetically attaching, screw-fitting, or bonding.
[0109] Specifically, if Fig. 9 and Fig.10 As shown, in this embodiment, the main body 1 and the mounting plate 5 are both horizontally arranged plate-like components, and actually form an integral structure stacked up and down. Two motors 2 are arranged inside the main body 1, and a winding reel 3 is installed on each motor 2. As a specific example, the holding member 4 is a holding rod, and the sliding fitting member 6 includes a pulley 61. A sliding fitting member 6 is respectively arranged at both ends of the holding rod serving as the holding member 4, wherein the pulley 61 of the sliding fitting member 6 is fixed to the two ends of the holding rod serving as the holding member 4 through an axis. Fig. 9 and Fig.10 As shown, when the free end Rf of the rope R is fixedly installed on the training accessory 5 by connecting the accessory connector Rc with the rope connector 51, the slide groove of the pulley 61 can be hung on the rope R so that when the user pulls the grip 4 to put the rope R in a tensioned state, the pulley 61 can slide along the rope R, thereby allowing the grip rod serving as the grip 4 to slide along the rope R.
[0110] This embodiment is the same as the above embodiment. Fig. 9 and Fig.10As shown, the free end Rf of the rope R at this time is combined with the rope connector 51 of the training accessory 5 through the accessory connector Rc and is installed on the training accessory 5, and the slide groove of the pulley 61 of the sliding matching member 6 of the gripping member 4 is hung on the rope R, so that the pulley 61 can slide along the rope R as a movable pulley. When the user pulls the gripping rod as the gripping member 4 to make it reciprocate, according to the force analysis of the movable pulley, it can be known that the force of the gripping member 4 located on the movable pulley is twice the force of the rope R. In other words, according to the utility model, double the motor output resistance can be obtained only through a simple structure, so that the output resistance can be increased at a low cost. In addition, a single motor can also be used in this embodiment.
[0111] The above describes the specific embodiments of the present invention, but the present invention is not limited thereto. Figure 1 and Fig. 9 The holding rod as the holding member 4 in the embodiment shown is replaced by Figure 5 The handle in the embodiment shown can also be Figure 5 The handle in the embodiment shown is replaced by Figure 1 and Fig. 9 The holding rod as the holding member 4 in the illustrated embodiment is not particularly limited.
[0112] In addition, in each embodiment, there is no limitation on the connection method between the accessory connector and the rope connector. It can be a threaded connection or a snap-on structure, a hook structure, or a magnetic structure as needed.
[0113] In addition, the grip 4 may be provided with a rope connector that can be connected to the accessory connector Rc of the rope R, or the grip 4 may be provided with a rope connector that is the same as the rope connector provided on the training accessories and the outer frame in the above-mentioned embodiments. In this case, the training accessories 5 may not be provided, and the rope connector of the grip 4 may be directly connected to the accessory connector Rc of the rope R. Specifically, Figures 11 to 13 As shown, by directly connecting the rope connector of the grip 4 with the accessory connector Rc of the rope R, the fitness equipment H can be used as a normal exercise equipment. In other words, in this state, when the user pulls the grip, the resistance on the grip is equal to the force on the rope R. Therefore, the utility model can realize the replacement of various accessories in a simple way, and can switch to a larger resistance exercise simply and quickly.
[0114] In addition, in the present invention, an example is given in which the sliding fitting has a pulley, but the present invention is not limited to this. A pulley block or a pulley frame unit can also be provided on the sliding fitting. For example, a plurality of pulleys can be used to clamp the rope, and the rope can be guided from multiple aspects, so that the user can exercise more smoothly.
[0115] Therefore, the utility model can increase the output resistance at a low cost without reducing the basic functions of the fitness equipment.
[0116] In addition, as mentioned above, there is no particular restriction on the number of motors in each embodiment. Figures 1 to 8 In the embodiment of the invention, the dual motor is used as an example to illustrate the advantages of the compactness of the overall structure of the fitness equipment, the simplification of the structure, and the significant cost reduction obtained by reducing the number of motors, the dual motor can be replaced with a single motor according to the actual situation, and only one motor is used by designing the internal pulley or pulley group of the main body, and the single-end rope output of the single motor is converted into a double-end rope output at the output end (such as the swing arm end, the free end of the rope) (for example, refer to Fig.14 and Fig.15 ). By improving the pulley and the pulley group inside the main body of the fitness equipment and designing the output path of the resistance generated by the motor, the structure of the dual motor can be cleverly simplified to the structure of a single motor, which can not only simplify the overall volume of the fitness equipment, but also reduce the number of relatively high-cost motors in the fitness equipment, so that the overall cost can be greatly reduced. However, in the case of a single motor, there may be a situation where the resistance output is insufficient, resulting in the single motor being unable to cope with low-position training movements such as heavy deadlifts and squats. However, in the utility model, by cleverly arranging the training accessories, it is possible to obtain double the motor output resistance through a simple structure, thereby being able to increase the output resistance at a low cost. Even in the case of a single motor, it is possible to cope with low-position training movements such as heavy deadlifts and squats with a simple structure without increasing the cost, and it is also possible to simplify the overall structure of the construction equipment.
[0117] In addition, the fitness equipment with resistance multiplication structure of the present invention can not only realize resistance multiplication, but also can change the multiple of resistance by using pulleys or pulley groups, for example, to realize resistance greater than twice or resistance less than one time.
[0118] The specific embodiments of the present invention are described above. However, those skilled in the art may make various modifications and changes to the embodiments of the present invention without departing from the spirit and scope of the present invention.
