Description

Technical Field

[0001] This invention relates to a fitness device, and more particularly to a fitness device suitable for various fitness movements and capable of improving safety. Background Technology

[0002] Generally, fitness equipment can only train a single muscle group, and users need to use a variety of different machines to train more muscle groups. For people who exercise at home, too much equipment can take up limited indoor space and is expensive. Furthermore, traditional fitness equipment typically provides weight through weight plates, requiring users to exert force to overcome the weight to achieve a training effect. However, this type of equipment can easily cause sports injuries when users are physically exhausted and unable to bear the weight. Summary of the Invention

[0003] To address the aforementioned technical problems, one technical solution adopted by this invention is to provide a fitness device comprising a moving component. The moving component includes a first rotary motor and a linear motor. The user operates the moving component by applying a force according to different movement trajectories of multiple training movements, causing the moving component to move linearly along an axis via the linear motor and rotate via the first rotary motor. The first rotary motor outputs a rotational resistance in response to the rotation of the moving component, and the linear motor outputs a linear resistance in response to the movement of the moving component. The rotational resistance and the linear resistance are combined into a resultant resistance, and the applied force is greater than the resultant resistance.

[0004] One of the beneficial effects of this invention is that the fitness device provided by this invention can respond to the rotation and movement of the moving parts through a first rotary motor and a linear motor, respectively, to output rotational resistance and linear resistance, allowing the user to achieve a training effect. Furthermore, the fitness device of this invention can apply resistance (push-pull resistance) tolerable to the trainee, enabling targeted training of specific muscle groups with correct movement posture, thereby achieving optimal exercise efficiency and effect.

Additionally, it should be understood that although terms such as "first," "second," and "third" may be used herein to describe various components, these components should not be limited by these terms. These terms are mainly used to distinguish one component from another. Furthermore, the term "or" as used herein may, depending on the actual situation, include any combination of one or more of the associated listed items.

[0017] See Figure 1 As shown, Figure 1 This is a schematic diagram of a moving component according to an embodiment of the present invention. The present invention provides a fitness device including a moving component 1, which includes at least a linear motor 11 and a first rotary motor 12. A user can operate the moving component 1 according to different movement trajectories of multiple training movements, causing the moving component 1 to move linearly along an axis via the linear motor 11 and to rotate via the first rotary motor 12. It should be noted that the linear motor 11 and the first rotary motor 12 of the present invention are mainly used to provide resistance. When the user operates the moving component 1, the first rotary motor outputs a rotational resistance in response to the rotation of the moving component 1, and the linear motor outputs a linear resistance in response to the movement of the moving component 1. The rotational resistance and the linear resistance are combined into a composite resistance.

[0018] This invention is not limited to the specific embodiment of the moving part 1. Figure 1 This is merely one possible embodiment and is not intended to limit the invention. Furthermore, any use of a combination of a linear motor and a rotary motor to provide resistance for users to exercise is an equivalent variation of the moving part 1 of the present invention.

[0019] Next, refer to Figure 2 and Figure 3 As shown, Figure 2 This is a schematic diagram of a fitness device according to an embodiment of the present invention. Figure 3This is a schematic diagram of a fitness device according to an embodiment of the present invention. The fitness device of the present invention is not limited by the number of moving parts 1. For example, the fitness device D may include two moving parts 1, which are fixed on a base B and spaced apart by a fixed distance. In addition to the linear motor 11 and the first rotary motor 12, the moving parts 1 further include a support body 13, an extension arm 14, and a force-applying accessory 15.

[0020] like Figures 1 to 3 As shown, the support body 13 is fixed to the base B. A first rotary motor 12 is connected between the support body 13 and the extension arm 14. A force-applying accessory 15 is connected to a linear motor 11. The force-applying accessory 15 can be, for example, a handle, a barbell bar, or a leg support roller; the present invention is not limited thereto. The user applies force to the force-applying accessory 15 with their hands or feet to drive the moving part 1. Therefore, more precisely, the aforementioned motion trajectory refers to the movement trajectory of the force-applying accessory 15. The first rotary motor 12 causes the extension arm 14 to rotate relative to the support body 13. The linear motor 11 causes the force-applying accessory 15 to move linearly relative to the extension arm 14.

[0021] like Figure 3 As shown, the fitness device D in this embodiment of the invention may further include a processing module 2 and a display module 3. The display module 3 is electrically connected to the processing module 2. The processing module 2 may be, for example, a microcontroller (MCU), which includes a computing unit 21 and a memory 22. The processing module 2 is disposed inside the fitness device D and electrically connected to the linear motor controller 111 of the linear motor 11 and the first rotation motor controller 121 of the first rotation motor 12. The display module 3 may be, for example, a fitness mirror, disposed on the support body 13, allowing the user to face the display module 3 during exercise to check whether their posture is correct.

[0022] Furthermore, the display module 3 may have a user interface 31. This invention is not limited to the specific form of the user interface 31. For example, the user interface 31 allows the user to select / input the body part to be trained, the training action to be performed on that body part, and the required resistance load. Therefore, the user can input a default composite resistance value through the user interface 31, causing the linear motor 11 and the first rotary motor 12 to output corresponding linear and rotary resistances. Thus, the user achieves the training effect by applying a force greater than this composite resistance, i.e., overcoming the resistance output by the linear motor 11 and the first rotary motor 12.

[0023] The application of the fitness device according to embodiments of the present invention will be further described next. See also... Figures 3 to 5 As shown, Figure 4 and Figure 5This is a schematic diagram illustrating a user operating the fitness device of this embodiment to perform a seated rowing motion. For example, when the user sets a combined resistance R via the display module 3 and begins operating the fitness device D of this invention to perform a seated rowing motion, the user grips the handle (i.e., the force-applying accessory 15) and applies a horizontal force F, pulling the moving part 1 closer to the body. Through the operation of the linear motor 11 and the first rotary motor 12, the force-applying accessory 15 generates a displacement L, and the extended arm 14 rotates by an angle (rotation angle θ). It should be noted that during the user's operation of the moving part 1, the magnitudes of the displacement L and the rotation angle θ will change depending on the position of the force-applying accessory 15.

[0024] More precisely, displacement L is the extension distance of moving part 1, and rotation angle θ is the rotation angle of moving part 1. At this time, the motion trajectory is a straight line in the horizontal direction. In response to the extension and rotation of moving part 1, linear motor 11 outputs linear resistance R1, and the first rotary motor 12 outputs rotational resistance R2. Linear resistance R1 and rotational resistance R2 can be combined into a resultant resistance R, and the linear resistance R1 and rotational resistance R2 satisfy the following relationship:

[0025] R1 = R × sin(θ);

[0026] R² = R × cos(θ);

[0027] See Figure 3 , Figure 6 and Figure 7 As shown, Figure 6 and Figure 7 This is a schematic diagram illustrating a user performing a barbell squat using the fitness device of this embodiment. For example, when a user performs a barbell squat using the fitness device D of this invention, the user uses the muscles between the shoulders and neck to support the barbell (i.e., the force application component 15), squatting down and then standing up. When standing up, the user applies a vertical force F, causing the linear motor 11 to generate a displacement L and the extended arm 14 to rotate by an angle (rotation angle θ). At this time, the trajectory is a straight line in the vertical direction. In response to the extension and rotation of the moving component 1, the linear motor 11 outputs linear resistance R1, and the first rotational motor 12 outputs rotational resistance R2. The linear resistance R1 and the rotational resistance R2 can be combined into a resultant resistance R, and the linear resistance R1 and the rotational resistance R2 satisfy the following relationship:

[0028] R1 = R × cos(θ);

[0029] R² = R × sin(θ);

[0030] Furthermore, considering the movements of seated rows and barbell squats, when the movement trajectory is a straight line, the resultant resistance R is parallel to the movement trajectory.

[0031] Next, refer to Figure 3 and Figure 8 As shown, Figure 8 This is a schematic diagram illustrating a user operating the fitness device of this embodiment to perform a seated thigh extension exercise. For example, when a user operates the fitness device D of this invention to perform a seated thigh extension exercise, the user extends their leg by using their lower leg to press against the roller (i.e., the force application component 15) and straightening their knee. At this time, the movement trajectory is curved, and the user's force direction is the tangential direction of the movement trajectory. In response to the drive of the moving component 1, the linear motor 11 outputs linear resistance R1, and the first rotary motor 12 outputs rotational resistance R2. The linear resistance R1 and the rotational resistance R2 are combined into a resultant resistance R. The resultant resistance R is parallel to the tangential direction of the movement trajectory, and the linear resistance R1 and the rotational resistance R2 conform to the following relationship (same as seated rowing):

[0032] R1 = R × sin(θ);

[0033] R² = R × cos(θ);

[0034] like Figure 3 As shown, the linear motor 11 includes a linear motor controller 111. The first rotary motor 12 includes a first rotary motor controller 121. The processing module 2 is electrically connected to the first rotary motor controller 121 and the linear motor controller 111. The first rotary motor controller 121 is used to detect the rotation angle θ, and the linear motor controller 111 is used to detect the displacement L. Further, the processing module 2 may include a computing unit 21 and a memory 22. The first rotary motor controller 121 and the linear motor controller 111 are used to transmit the detected rotation angle θ and displacement L to the memory 22 of the processing module 2 for storage.

[0035] See Figure 3 and Figure 10 As shown, Figure 10 This is a schematic diagram of the internal information of the processing module of the fitness device according to an embodiment of the present invention. The trajectory of each exercise, such as seated rowing, barbell squat, and seated thigh extension, is composed of multiple coordinate points. Each coordinate point has information on a displacement L and a rotation angle θ. The memory 22 of the processing module 2 stores the coordinate points of multiple different motion trajectories and their displacement and rotation angle information.

[0036] For example, such as Figure 10As shown, the motion trajectory is composed of multiple coordinate points, such as coordinate point a(Xa,Ya,Za), coordinate point b(Xb,Yb,Zb), ..., coordinate point z(Xz,Yz,Zz). Coordinate point a has a rotation angle θ(a) and a displacement L(a), where displacement L(a) is the distance the moving part 1 extends to coordinate point a, and rotation angle θ(a) is the angle by which the moving part 1 rotates to coordinate point a. Similarly, coordinate point b has a rotation angle θ(b) and a displacement L(b), where displacement L(b) is the distance the moving part 1 extends to coordinate point b, and rotation angle θ(b) is the angle by which the moving part 1 rotates to coordinate point b; coordinate point z has a rotation angle θ(z) and a displacement L(z), where displacement L(z) is the distance the moving part 1 extends to coordinate point z, and rotation angle θ(z) is the angle by which the moving part 1 rotates to coordinate point z.

[0037] Furthermore, at different coordinate points, the extension distance and rotation angle of the moving part 1 are different. In addition, due to the different extension distances and rotation angles, the linear resistance output by the linear motor 11 and the rotational resistance output by the first rotary motor 12 at different coordinate points are also different. Furthermore, the memory 22 of the processing module 2 further stores the resistance information corresponding to each coordinate point, namely the linear resistance output by the linear motor 11 for the corresponding extension distance and the rotational resistance output by the first rotary motor 12 for the corresponding rotation angle.

[0038] To further explain the operating mechanism of the fitness device D of the present invention, the following will use... Figure 4 and Figure 5 The example used is a seated rowing motion. Additionally, for clarity, please refer to the [reference needed]. Figure 2 and Figure 3 As shown. For example, a user can initially select the seated rowing motion and set a combined resistance of 10 kg through the user operation interface 31 of the display module 3.

[0039] When the user operates the fitness device D to perform a seated rowing exercise, such as... Figure 4In the stage shown, the displacement L can be, for example, 20cm, and the rotation angle θ can be, for example, 30 degrees. The linear motor controller 111 and the first rotary motor controller 121 respectively feed back the displacement L (20cm) output by the linear motor 11 and the rotation angle θ (30 degrees) output by the first rotary motor 12 to the processing module 2. The calculation unit 21 of the processing module 2 can identify the coordinate point of the user's current action based on the displacement L and rotation angle θ detected by the linear motor controller 111 and the first rotary motor controller 121, and output the resistance information corresponding to the coordinate point to the linear motor controller 111 and the first rotary motor controller 121. Based on this resistance information, the linear motor controller 111 controls the linear motor 11 to output a linear resistance R1 of 5kg, and the first rotary motor controller 121 controls the first rotary motor 12 to output a rotational resistance R2 of 8.66kg, so that the linear resistance R1 and the rotational resistance R2 can be combined into a composite resistance R of 10kg.

[0040] Next, when the user operates the fitness device D to perform seated rowing movements, such as... Figure 5 In the stage shown, the displacement L can be, for example, 80 cm, and the rotation angle θ can be, for example, 60 degrees. The linear motor controller 111 and the first rotary motor controller 121 respectively feed back the displacement L output by the linear motor 11 and the rotation angle θ output by the first rotary motor 12 to the processing module 2. The calculation unit 21 of the processing module 2 can identify the coordinate point of the user's current action based on the displacement L (80 cm) and rotation angle θ (60 degrees) detected by the linear motor controller 111 and the first rotary motor controller 121, and output the resistance information corresponding to the coordinate point to the linear motor controller 111 and the first rotary motor controller 121. Based on this resistance information, the linear motor controller 111 controls the linear motor 11 to output a linear resistance R1 of 8.66 kg, and the first rotary motor controller 121 controls the first rotary motor 12 to output a rotational resistance R2 of 5 kg, so that the linear resistance R1 and the rotational resistance R2 can be combined into a composite resistance R of 10 kg.

[0041] It should be noted that when the user operates the moving part 1 with incorrect movements, the displacement and rotation angle detected by the linear motor controller 111 and the first rotary motor controller 121 will not match the displacement L and rotation angle θ of the coordinate point of the correct movement. As a result, the calculation unit 21 cannot distinguish between them, and therefore the calculation unit 21 will not output the corresponding resistance information to the linear motor controller 111 and the first rotary motor controller 121. In other words, if the user operates the moving part 1 with incorrect movements, the linear motor controller 111 and the first rotary motor controller 121 will not be able to output resistance for the user's training. Alternatively, if the user's movement posture is incorrect and the push or pull is not performed according to the correct movement trajectory, the moving part 1 cannot be moved.

[0042] See Figure 3 and Figure 9 As shown, Figure 9 This is a schematic diagram of a fitness device according to another embodiment of the present invention. (Comparison) Figure 2 and Figure 9 It is understood that the moving part 1 may also include a second rotating motor 16, which can be connected between the support body 13 and the base B. The second rotating motor 16 can cause the support body 13 to rotate relative to the base B.

[0043] For example, when the user operates Figure 9 When the fitness device D shown simulates the chest press movement of a butterfly machine, the user holds the handle (i.e., the force application accessory 15) and applies a force to the moving part 1, causing the moving part 1 to rotate by an angle (azimuth angle) via the second rotary motor 16. The second rotary motor 16 outputs a second rotational resistance in response to the rotation of the moving part 1. It should be noted that the extension direction of the shaft of the second rotary motor 16 is different from that of the shaft of the first rotary motor 12. More precisely, the extension direction of the shaft of the second rotary motor 16 is perpendicular to the extension direction of the shaft of the first rotary motor 12.

[0044] Therefore, the coordinates of the chest-clamping motion trajectory include not only information about displacement L and rotation angle θ, but also azimuth angle. The information, as mentioned above, azimuth angle. This refers to the rotation angle of the moving part 1 via the second rotary motor 16. The second rotary motor 16 includes a second rotary motor controller 161 electrically connected to the processing module 2. The second rotary motor controller 161 is used to detect the azimuth angle. and the detected azimuth angle The data is transmitted to processing module 2 for storage. Furthermore, the resistance information stored in memory 22 of processing module 2 includes not only the linear resistance output by linear motor 11 corresponding to displacement L and rotational resistance output by first rotary motor 12 corresponding to rotation angle θ, but also the azimuth angle of second rotary motor 16. The output is the second rotational resistance.

[0045] Therefore, the calculation unit 21 of the processing module 2 can calculate the displacement L, rotation angle θ, and azimuth angle detected by the linear motor controller 111, the first rotation motor controller 121, and the second rotation motor controller 161. The system identifies the coordinates of the user's current action and outputs the corresponding resistance information to the linear motor controller 111, the first rotary motor controller 121, and the second rotary motor controller 161. The linear motor controller 111, the first rotary motor controller 121, and the second rotary motor controller 161 then control the resistance output of the linear motor 11, the first rotary motor 12, and the second rotary motor 16 based on this resistance information.

[0046] like Figure 3 As shown, the fitness device D in this embodiment of the invention may further include a communication module 4, which is electrically connected to the processing module 2. The communication module 4 is capable of connecting to the user's mobile device E, such as a smartphone, via a network. Thereby, the user can issue commands to the processing module 2 through an application built into the mobile device E, selecting the desired training movements (such as seated rows, barbell squats, seated thigh extensions, and butterfly machine chest presses) and setting the required combined resistance.

[0047] In summary, the fitness device D provided by this invention can simulate various movements, such as bicep curls, deadlifts, leg presses, and bench presses, through a combination of a linear motor 11 and rotary motors (a first rotary motor 12 and a second rotary motor 16), thereby training different body parts. Furthermore, the fitness device provided by this invention allows users to set horizontal or vertical resistance as needed, enabling them to apply horizontal pushing or vertical lifting forces to perform targeted training of specific muscle groups, achieving optimal exercise efficiency and results.

[0048] It should be noted that the fitness device D of this invention only utilizes the resistance output by the motor for exercise, and the resistance of the motor is only generated when the user operates the moving part 1. In other words, if the user releases the moving part 1 due to fatigue during exercise, the motor resistance will disappear. Therefore, the user does not need to worry about putting extra load on the body and causing sports injuries by releasing the moving part 1.

[0049] In addition, users can select / input the body part to be trained, the training movements to be performed on that body part, and the required resistance load through the user interface 31 of the display module 3 of the fitness device D or the built-in application of the mobile device E. When the user is a beginner, the output composite resistance value can be set to 0 to enter a coach mode. In coach mode, when the user operates the motion component 1, the linear motor 11 and the rotary motors (first rotary motor 12 and second rotary motor 16) will not output resistance, so the user can familiarize themselves with the training posture. After the user is familiar with the movements, the appropriate composite resistance value can be gradually set for exercise.

[0050] Therefore, the fitness device D of the present invention can avoid sports injuries caused by incorrect exercise posture, force and accidents, allowing users to exercise in a safe and stable state, thereby improving the motivation and safety of fitness exercise.

[0051] The content disclosed above is only a preferred and feasible embodiment of the present invention, and is not intended to limit the scope of the patent application of the present invention. Therefore, all equivalent technical changes made using the contents of the present invention specification and drawings are included in the scope of the patent application of the present invention.
