Description

[Technical field]

[0001] The present invention relates to a training device and a method of using the same, and more particularly to a training device that assists a user and a method of using the same. [Background technology]

[0002] Conventional training machines are bulky, which is disadvantageous for users (general users or users with disabilities) to use. Furthermore, most of the conventional training machines are passive, that is, they need to generate resistance by using the weight of the machine itself to achieve the purpose of training. However, when a user needs to train through different weights, the number of training machines increases accordingly, which causes inconvenience to the user.

[0003] In addition, when a user trains alone using a conventional training machine, the user often fails to obtain training effects due to incorrect posture due to the lack of a feedback support function, and often ends up getting injured. Furthermore, conventional training machines cannot provide additional training-related information based on training results for the user to further refer to. Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention has been made in consideration of the above circumstances, and an object of the present invention is to provide a training device and a method for using the same. [Means for solving the problem]

The body assembly includes a housing and a drive element. The drive element is mounted on the housing. The first attachment assembly includes a first rod and a first mounting element. One end of the first rod is coupled to the drive element. The drive element drives the first rod to rotate.

[0006] The present invention further provides a method for using a training device, including the steps of: a drive device of the drive element detecting an external force provided by a user through a first rod; upon detection of the external force, a controller of the drive element calculating an assisting force for driving the first rod based on a gain value; and the controller of the drive element controlling the drive device to drive the first rod with the assisting force.

[0011] 1, a three-dimensional view of a training device 1 according to some embodiments of the present invention is shown. Specifically, the training device 1 includes a body assembly 11 and an attachment assembly 13. The body assembly 11 includes a housing 111 and a drive element 113.

In some embodiments, the position of the attachment element 133 provided on the rod 131 can be adjusted to fit different user body types.

[0013] 2A, a three-dimensional view of a training device 2 according to some embodiments of the present invention is shown. Specifically, the training device 2 includes a body assembly 21 and an attachment assembly 23. The body assembly 21 includes a housing 211, a driving element 213, and an interface element 215. The driving element 213 and the interface element 215 are provided in the housing 211. In some embodiments, the housing 211 defines an internal accommodation space, and the driving element 213 is partially provided inside the housing 211 (as shown by the dashed line in FIG. 2A). In some embodiments, the housing 211 may be open type, and the driving element 213 is provided on the housing 211.

[0014] In some embodiments, the attachment assembly 23 includes a rod 231 and an attachment element 233. In particular, one end of the rod 231 is coupled to the driving element 213, and the attachment element 233 includes a first fastening means 2331 and a second fastening means 2333. The first fastening means 2331 is used to mount the attachment element 233 on the rod 231, and the second fastening means 2333 is used to mount (e.g., wear) on a user (not shown). In some embodiments, the first fastening means 2331 includes a releasable snap-fit ​​coupling structure and is used to adjust the position of the attachment element 233 mounted on the rod 231 to accommodate different body types of users.

[0015] In some embodiments, when the attachment element 233 is attached to a user, the drive element 213 can be used to drive the rod 231 in rotation (rotation R20 shown in FIG. 2A ), and by rotating the rod 231 to move the attachment element 233, an associated assistive force (e.g., an assistive force in the same direction as the user's manipulation direction or a resistive force in the opposite direction) is provided to the user to achieve a training effect.

[0016] 2B together, a schematic diagram of the use of the training device 2 according to some embodiments of the present invention. Specifically, the interface element 215 of the body assembly 21 protrudes outward from the housing 211 and is used to interface with an external device 9 (e.g., a chair). The external device 9 includes a structure for receiving and fixing the interface element 215, and after the training device 2 is fixed to the external device 9 via the interface element 215, the user can lean on the external device 9 (e.g., sit on a chair), wear the second fixing means 2333 on the user's calves, and move the calves to operate the training device 2. In some embodiments, the interface element 215 includes a pin for inserting into and fixing to the structure 91 of the external device 9.

[0017] 2C, which is an enlarged view of the corresponding structure 91 of the external device 9 of the present invention. In detail, the structure 91 corresponds to the number of pins of the connecting element 215 and has holes 910 for receiving the connecting element 215. The structure 91 includes a releasable snap-fit ​​coupling structure 913, and when the snap-fit ​​coupling structure 913 is released, the connecting element 215 can be inserted into the corresponding hole 910, and then the snap-fit ​​coupling structure 913 can be firmly locked to fix the connecting element 215 in the hole 910.

[0018] 2D together, a block diagram of the driving element 213 of some embodiments of the present invention is shown. Specifically, the driving element 213 includes a driving device 2131 and a controller 2133, and the driving device 2131 is electrically connected to the controller 2133 and can transmit an electric signal between the two. The driving device 2131 may include a motor, and the controller 2133 may include a micro control unit (MCU) for controlling the motor of the driving device 2131. More specifically, the driving device 2131 is used to provide an auxiliary force for driving the rod 231. The controller 2133 is used to control at least one of the strength, period, and operation range of the auxiliary force provided by the driving device 2131.

[0019] In some embodiments, the driving device 2131 can detect an external force provided by the user through the rod 231, i.e., a force with which the user operates the training apparatus 2. Upon detecting the external force, the controller 2133 can calculate an assist force based on a gain value and control the driving device 2131 to drive the rod 231 with the assist force.

[0020] In some embodiments, the training apparatus 2 can provide different training modes. The controller 2133 can calculate an assist force based on the different training modes and control the drive device 2131 to provide the assist force to the user. Here, the training apparatus 2 can provide an isokinetic mode, an isotonic mode, or an isometric mode.

[0021] In some embodiments, when the training apparatus 2 provides a constant velocity mode, the driving device 2131 detects the operation speed generated when the user operates the rod 231. The controller 2133 determines whether the operation speed exceeds a threshold. If the operation speed exceeds the threshold, the controller 2133 controls the driving device 2131 to dynamically adjust the strength of the assist force so that the operation speed does not exceed the threshold.

[0022] In some embodiments, when the training device 2 provides an isotonic mode, the controller 2133 controls the driver 2131 to provide a constant strength of assistive force to the user.

[0023] In some embodiments, when the training apparatus 2 provides an isometric mode, the controller 2133 locks the driver 2131 so that the strength of the assistive force provided by the driver 2131 is used to offset the strength of the external force generated by the user manipulating the rod 231.

[0024] In some embodiments, the driver 2131 detects the amount of rotation that occurs when the rod 231 is operated. If the amount of rotation exceeds a certain operating range, the controller 2133 controls the driver 2131 to stop operation.

[0025] 3A, a three-dimensional view of a training device 3 according to some embodiments of the present invention. Specifically, the training device 3 includes a body assembly 31, a first attachment assembly 33, a second attachment assembly 35, and a movable element 37. The body assembly 31 includes a housing 311, a driving element 313, and a joint element 315. The driving element 313 and the joint element 315 are provided in the housing 311. In some embodiments, the housing 311 defines an internal accommodation space, and the driving element 313 is partially provided inside the housing 311 (as shown by the dashed line in FIG. 3A). In some embodiments, the housing 311 may be open type, and the driving element 313 is provided on the housing 311.

[0026] In some embodiments, the first attachment assembly 33 includes a first rod 331 and a first mounting element 333. More specifically, one end of the first rod 331 is coupled to the driving element 313, and the first mounting element 333 includes a first fastening means 3331 and a second fastening means 3333. The first fastening means 3331 is used to mount the first mounting element 333 on the first rod 331, and the second fastening means 3333 is used to mount (e.g., wear) on a user (not shown). In some embodiments, the first fastening means 3331 includes a releasable snap-fit ​​coupling structure, and is used to adjust the position of the first mounting element 333 mounted on the first rod 331 to accommodate different body types of users.

[0027] In some embodiments, when the first attachment element 333 is attached to a user, the drive element 313 can be used to drive the first rod 331 to rotate (rotation R30 shown in FIG. 3A ), and by rotating the first rod 331 to move the first attachment element 333, an associated assistive force (e.g., an assistive force in the same direction as the user's operation direction or a resistive force in the opposite direction) is provided to the user to achieve a training effect.

[0028] 3B, which is an enlarged view of the movable element 37 of the present invention. In some embodiments, the movable element 37 includes a first rotating means 371 and a second rotating means 373. Specifically, the first rotating means 371 can rotate about a first rotation axis Y1, and the second rotating means 373 can also rotate about a second rotation axis Y2. In some embodiments, the first rotation axis Y1 is different from the second rotation axis Y2, which increases the user's freedom to operate the training apparatus 3.

[0029] The interface element 315 of the body assembly 31 protrudes outward from the housing 311 and is used to interface with the first rotating means 371. The first rotating means 371 includes a hole 3710 for receiving and securing the interface element 315. In some embodiments, the interface element 215 includes a pin for inserting into and securing in the hole 3710 of the first rotating means 371.

[0030] In some embodiments, the first rotating means 371 includes two clamping pieces 3711 and a rotating knob 3713. When the two clamping pieces 3711 are coupled together, a groove formed thereon identifies the hole 3710. The rotating knob 3713 is used to adjust the tightness of the coupling of the two clamping pieces 3711. For example, when the rotating knob 3713 is rotated in a clockwise (or counterclockwise) direction, the coupling of the two clamping pieces 3711 becomes loose, and at this time, the joining element 315 can be inserted into the hole 3710. Next, the rotating knob 3713 is rotated in a counterclockwise (or clockwise) direction to increase the tightness of the coupling of the two clamping pieces 3711, and the joining element 315 is clamped in the hole 3710.

[0031] In some embodiments, the second attachment assembly 35 includes a second rod 351 and a second mounting element 353. In particular, one end of the second rod 351 is connected to the movable element 37, and the second mounting element 353 is provided on the second rod 351. In some embodiments, the movable element 37 includes a ring-like structure 375 for fitting the second rod 351 to an adjustable tightening condition. Through this structure, the movable element 37 can adjust the position that needs to be fixed on the second rod 351 and can rotate around the axis Y3 of the second rod 351.

[0032] In some embodiments, the second mounting element 353 includes an adjustable through hole for fitting the second rod 351 from one end of the second rod 351. The second mounting element 353 adjusts the position that needs to be fixed on the second rod 351 and is fixed via a snap-fit ​​coupling device 3531. Therefore, it can be adapted to different body types of users through the installation of the above structure.

[0033] Please refer to Figures 3C, 3D and 3E together. Figures 3C and 3D are schematic diagrams of the use of the training device 3 according to some embodiments of the present invention, and Figure 3E is a three-dimensional diagram of the attachment 3335 of the training device 3 according to some embodiments of the present invention. Specifically, the second attachment element 353 of the second attachment assembly 35 is used to join to the external device 8 (e.g., a table). In some embodiments, in order to improve the flexibility of the use of the training device 3, the second attachment element 353 further includes a clamping fixture 3533 for clamping and fixing at different positions of the external device 8. After the training device 3 is fixed to the external device 8 via the second attachment assembly 35, the user 7 can operate the training device 3 by wearing the second fixing means 3333 (e.g., worn on the forearm) near the external device 8 (e.g., sitting on a chair beside the table). In some embodiments, in order to allow the user 7 to operate the training device 3 more conveniently, an attachment 3335 having a handle can be disposed on the first attachment element 333 to make it easy for the user 7 to hold and operate it.

[0034] Therefore, through (1) the installation of the first rotating means 371 and the second rotating means 373 of the movable element 37, (2) the position of the movable element 37 on the second rod 351, (3) the position of the second mounting element 353 on the second rod 351, and (4) the position of the second mounting element 353 clamped and fixed to the external device 8, the training device 3 has more freedom of operation and can effectively adapt to various body types of users.

[0035] Referring to FIG. 3F, a block diagram of the driving element 313 according to some embodiments of the present invention is shown. Specifically, the driving element 313 includes a driving device 3131 and a controller 3133, and the driving device 3131 is electrically connected to the controller 3133 and can transmit an electrical signal between the two. The driving device 3131 may include a motor, and the controller 3133 may include an MCU for controlling the motor of the driving device 3131. More specifically, the driving device 3131 is used to provide an auxiliary force for driving the first rod 331. The controller 3133 is used to control at least one of the strength, period, and operation range of the auxiliary force provided by the driving device 3131.

[0036] In some embodiments, the driving device 3131 can detect an external force provided by the user through the first rod 331, i.e., a force with which the user operates the training apparatus 3. Upon detecting the external force, the controller 3133 can calculate an assist force based on a gain value and control the driving device 3131 to drive the first rod 331 with the assist force.

[0037] In some embodiments, the training device 3 can provide different training modes. The controller 3133 can calculate an assist force based on the different training modes and control the drive device 3131 to provide the assist force to the user. Here, the training device 3 can provide an isokinetic mode, an isotonic mode, or an isometric mode.

[0038] In some embodiments, when the training apparatus 3 provides a constant velocity mode, the driving device 3131 detects the operation speed generated when the user operates the first rod 331. The controller 3133 determines whether the operation speed exceeds a threshold. If the operation speed exceeds the threshold, the controller 3133 controls the driving device 3131 to dynamically adjust the strength of the assist force so that the operation speed does not exceed the threshold.

[0039] In some embodiments, when the training device 3 provides an isotonic mode, the controller 3133 controls the driver 3131 to provide a constant strength of assistive force to the user.

[0040] In some embodiments, when the training device 3 provides an isometric mode, the controller 3133 locks the drive device 3131 so that the strength of the assistive force provided by the drive device 3131 is used to offset the strength of the external force generated by the user manipulating the first rod 331.

[0041] In some embodiments, the driver 3131 detects the amount of rotation caused when the first rod 331 is operated. If the amount of rotation exceeds a certain operating range, the controller 3133 controls the driver 3131 to stop operation.

[0042] Referring to FIG. 4A, it is a schematic diagram of a training system 4 according to some embodiments of the present invention. Specifically, the training system 4 includes a training device 41 (e.g., the above-mentioned training device 1, 2 or 3), a server 43, and a client device 45. When the training device 41 performs the relevant user's operation of the above-mentioned embodiment, the driving device (e.g., the above-mentioned driving device 2131 or 3131) of the training device 41 can detect the operation data 410 of the training device 41 during the operation process. Then, the controller (e.g., the above-mentioned controller 2133 or 3133) of the training device 41 can transmit the operation data 410 to the server 43 through a network using a transmission means (not shown) of the training device 41.

[0043] Next, the server 43 can determine at least one piece of training information 430 based on the operation data 410. In detail, the operation data 410 may include at least relevant data such as the external force with which the user operates the training device 41, the assisting force provided by the training device 41, the range of rod operation of the training device 41, etc., and the server 43 can determine training information such as (1) whether the user encounters a problem when operating the training device 41, (2) whether the user's training amount is excessive or insufficient, and (3) whether the user's training posture is appropriate, based on these operation data. Then, the server 43 can provide at least one piece of training information 430 to the client device 45 through the network, and the user can check whether the training situation meets his or her needs.

[0044] It is worth noting that the process of the server 43 determining at least one piece of training information 430 based on the operation data 410 may utilize technologies such as big data, artificial intelligence, and machine learning. Specifically, the server 43 first collects various operation data and corresponding training information data, and establishes a judgment module based on the data through the methods of artificial intelligence and machine learning. Therefore, when the server 43 receives related operation data at a later date, the operation data can be input into the judgment module to directly obtain the training information.

[0045] In some embodiments, the server 43 determines at least one item 432 corresponding to the training information 430 based on the training information 430, and provides the at least one item 432 to the client device 45 through a network, so that the user can conveniently refer to the related item 432. For example, if the training information 430 indicates that the user may need a specific course or product, the server 43 can determine at least one item 432 (e.g., a network link or image of the course or product) corresponding to the course or product based on the training information 430. The server 43 can then provide the at least one item 432 to the client device 45 through a network, and the client device 45 can use the display means 451 to display the training information 430 and the item 432 in a graphical user interface (e.g., the graphical user interface shown in FIG. 4B ). Here, the item 432 can include a quick response code (QR code).

[0046] Some embodiments of the present invention include a method of using a training device (such as the training device of the previous embodiments), and a flow chart is shown in FIG. 5. The detailed operations of the method are as follows: First, the driving device of the training device performs step S501 of detecting an external force provided by a user through a first rod. Upon detecting the external force, the controller performs step S502 of calculating an auxiliary force for driving the first rod based on a gain value. The controller performs step S503 of controlling the driving device to drive the first rod with the auxiliary force.

[0047] Some embodiments of the present invention include a method of using a training device (such as the training device of the previous embodiments), the flow chart of which is shown in Figures 6A-6C. The detailed operation of the method is as follows.

[0048] First, the driving device of the training device performs step S601 of detecting an external force provided by a user through a first rod. Upon detecting the external force, the controller performs step S602 of calculating an auxiliary force for driving the first rod based on a gain value. The controller performs step S603 of controlling the driving device to drive the first rod with the auxiliary force. It is noteworthy that in some embodiments, the training device may provide different training modes. The controller may calculate an auxiliary force based on the different training modes and control the driving device to provide the auxiliary force to the user. Here, the training device may provide an isokinetic mode, an isotonic mode, or an isometric mode.

[0049] In some embodiments, if the training device provides a constant-kinetic mode, the drive device further executes step S604 of detecting an operation speed occurring when the user operates the training device. The controller executes step S605 of determining whether the operation speed exceeds a threshold. If the operation speed exceeds the threshold, the controller executes step S606 of controlling the drive device to dynamically adjust the strength of the assist force so as not to cause the operation speed to exceed the threshold. If the operation speed does not exceed the threshold, step S604 is repeatedly executed.

[0050] In some embodiments, if the training device provides an isotonic mode, step S603 further includes the step of the controller controlling the driver to provide a constant intensity of assist force to the user.

[0051] In some embodiments, if the training device provides an isometric mode, step S603 further includes the step of the controller locking the actuator so that the strength of the assistive force provided by the actuator is used to offset the strength of the user's operating force.

[0052] In some embodiments, the method includes detecting the operation range. Specifically, the actuator performs step S607 to detect the amount of rotation caused when the first rod is operated. The controller performs step S608 to determine whether the amount of rotation exceeds the operation range. If it does, the controller performs step S609 to control the actuator to stop operation. If it does not, step S607 is repeated.

[0053] Some embodiments of the present invention include a method of using a training device (such as the training device of the previous embodiments), the flow chart of which is shown in Figures 7A-7B. The detailed operation of the method is as follows.

[0054] First, the driving device of the training device executes step S701 of detecting an external force provided by a user through the first rod. Upon detecting the external force, the controller executes step S702 of calculating an auxiliary force for driving the first rod based on a gain value. The controller executes step S703 of controlling the driving device to drive the first rod with the auxiliary force.

[0055] Next, the driving device performs step S704 of detecting operation data of the training device. The controller performs step S705 of transmitting the operation data to the server through the network using the transmission means of the training device. The server performs step S706 of determining at least one training information based on the operation data. The server performs step S707 of providing the at least one training information to the client device through the network. The client device performs step S708 of displaying the at least one training information in a graphical user interface through the display means.

[0056] In some embodiments, after step S706, the server optionally performs step S709 of determining at least one item corresponding to the at least one training information based on the at least one training information. After step S709, the server performs step S710 of providing the at least one item to the client device through a network. After step S710, the client device performs step S711 of displaying the at least one training information and the at least one item in a graphical user interface via a display means, where the at least one item includes a QR code.

[0057] Although the specification contains many specific implementation details, these should not be construed as limiting the scope of any feature or subject matter that may be claimed, but rather as describing features specific to particular embodiments. Certain features described in the specification in the context of separate embodiments may also be implemented in combination in a single embodiment.
