TECHNICAL FIELD

The present disclosure relates to a training device and a utilizing method thereof, and more particularly, to a training device for assisting a user and a utilizing method thereof.

BACKGROUND

Conventional training apparatuses have large volumes that may be disadvantageous to users (including both non-disabled users and users with disabilities). Moreover, conventional training apparatuses are mostly passive; that is, the weight of the apparatus itself needs to be used to produce a resistive force in order to achieve the objective of training. However, when a user trains using different weights, the number of training apparatuses increases, leading to inconvenience of the user.

In addition, when a user trains alone using a conventional training apparatus, because such conventional training apparatus lacks the function of feedback assistance, the user may frequently suffer from poor training results or even be injured due to incorrect form. Moreover, conventional training apparatuses cannot provide additional training-related information according to training results for further references for the user.

The main assembly includes a housing and a driving component disposed in the housing. The first attachment assembly includes a first rod, one end of the first rod being connected to the driving component. The driving component drives the first rod to rotate. The accessory includes a handle and a grip disposed on another end of the first rod. The handle is slidable relative to the grip.

The present disclosure further provides a utilizing method of the training device. The method includes detecting, by the driver, an external force applied by a user through the first rod and the accessory, calculating, by the controller, the auxiliary force based on a gain according to the detection of the external force, and controlling, by the controller, the driver to drive the first rod with the auxiliary force.

The main assembly 11 includes a housing 111, a driving component 113 and an engaging component 115. In some embodiments, the driving component 113 and the engaging component 115 are disposed in the housing 111. In some embodiments, the housing 111 defines an internal accommodating space, and the driving component 113 is disposed partially inside the housing 111 (as shown by dotted lines in FIG. 1). In some embodiments, the housing 111 is in an open form, and the driving component 113 is disposed on the housing 111. In some embodiments, the driving component 113 includes a releasable fastening structure 1132 that is used to fix the attachment assembly 13.

In some embodiments, the attachment assembly 13 includes a rod 131 and an attachment component 133. One end of the rod 131 is connected to the driving component 113, and the attachment component 133 is disposed on the rod 131 and is configured to attach to (for example, to be worn by) a user (not shown). In some embodiments, the attachment component 133 includes a first fixing unit 1331 and a second fixing unit 1333. The first fixing unit 1331 is used to dispose the attachment component 133 on the rod 131, and the second fixing unit 1333 is used to attach to a user. In some embodiments, the first fixing unit 1331 includes a releasable fastening structure used to adjust a position at which the attachment component 133 is disposed on the rod 131, so as to match a body size of the user.

When the attachment component 133 is attached to the user, the driving component 113 can be used to drive the rod 131 to rotate (as shown by rotation R10 in FIG. 1). By means of rotating the rod 131 to drive the attachment component 133, the user is provided with an associated auxiliary force (e.g., an assisting force in a same direction as, or a resistive force in a direction opposite to, an operating direction of the user), so as to achieve a training effect. In some embodiments, a position at which the attachment component 133 is disposed on the rod 131 is adjustable so as to match a body size of the user. In some embodiments, the training device 1 further includes an accessory having a handle can be configured on the first attachment component 133 to facilitate holding and operations of the user. The accessory is described later.

FIG. 2 is a block diagram of the driving component 113 of FIG. 1, in accordance with some embodiments of the present disclosure. The driving component 113 includes a driver 1131 and a controller 1133. The driver 1131 is electrically connected to the controller 1133, and the electrical signals can be transmitted between the driver 1131 and the controller 1133. The driver 1131 may include a motor, and the controller 1133 may include a micro control unit (MCU) used to control the motor of the driver 1131. Furthermore, the driver 1131 is used to provide an auxiliary force so as to drive the rod 131. The controller 1133 is used to control at least one of a strength, a time period and an operating range of the auxiliary force provided by the driver 1131.

In some embodiments, the driver 1131 can detect an external force applied by a user through the rod 131, that is, the force by which the user operates the training device 1. Based on the detected external force, the controller 1133 can calculate the required auxiliary force based on a gain and control the driver 1131 to drive the rod 131 with the auxiliary force.

In some embodiments, the training device 1 can provide several different training modes. The controller 1133 can calculate the required auxiliary force based on different training modes, and can control the driver 1131 to provide the required auxiliary force to the user. The training device 1 can provide an isokinetic mode, an isotonic mode or an isometric mode.

In some embodiments, when the training device 1 provides the isokinetic mode, the driver 1131 detects an operating speed produced when the user operates the rod 131 through the accessory. The controller 1133 determines whether the operating speed exceeds a threshold. When the operating speed exceeds the threshold, the controller 1133 controls the driver 1131 to dynamically adjust the strength of the auxiliary force, so that the operating speed does not become greater than the threshold.

In some embodiments, when the training device 1 provides the isotonic mode, the controller 1133 controls the driver 1131 to provide a fixed auxiliary force to the user.

In some embodiments, when the training device 1 provides the isometric mode, the controller 1133 locks the driver 1131, such that the strength of the auxiliary force provided by the driver 1131 cancels the external force generated by the user operating the rod 131.

In some embodiments, the driver 1131 detects a rotation amount produced when the rod 131 is operated. When the rotation amount exceeds a predetermined operating range, the controller 1133 controls the driver 1131 to stop operating.

In some embodiments, the first attachment assembly 33 includes a first rod 331 and a first attachment component 333. Specifically, one end of the first rod 331 is connected to the driving component 313, and the first attachment component 333 includes a first fixing unit 3331 and a second fixing unit 3333. The first fixing unit 3331 is used to dispose the first attachment component 333 on the first rod 331, and the second fixing unit 3333 is used to attach to (for example, to be worn by) a user (not shown). In some embodiments, the first fixing unit 3331 includes a releasable fastening structure used to adjust a position at which the first attachment component 333 is disposed on the first rod 331, so as to match a body size of the user.

In some embodiments, when the first attachment component 333 is attached to a user, the driving component 313 can be used to drive the first rod 331 to rotate. By means of rotating the first rod 331 to drive the first attachment component 333, the user is provided with an associated auxiliary force (e.g., an assisting force in a same direction as, or a resistive force in an opposite direction to, an operating direction of the user), so as to achieve a training effect.

In some embodiments, the second attachment assembly 35 includes a second rod 351 and a second attachment component 353. One end of the second rod 351 is connected to the movable component 37, and the second attachment component 353 is disposed on the second rod 351.

The position at which the second attachment component 353 needs to be secured on the second rod 351 is adjustable, and the second attachment component 353 is secured by a fastening device 3531. Thus, the structure can match body sizes of different users.

FIG. 4 is an enlarged diagram of the movable component 37 of FIG. 3, in accordance with some embodiments of the present disclosure. The movable component 37 includes a first rotating unit 371 and a second rotating unit 373. The first rotating unit 371 is rotatable about a first rotating axis Y1, and the second rotating unit 373 is rotatable about a second rotating axis Y2. In some embodiments, the first rotating axis Y1 is different from the second rotating axis Y2, so as to increase the degree of freedom for operating the training device 3 by the user. In some embodiments, the first rotating unit 371 and the second rotating unit 373 can rotate 360 degrees.

In some embodiments, the engaging component 315 of the main assembly 31 protrudes outward and extends from the housing 311, and is used to engage with the first rotating unit 371.

In some embodiments, the first rotating unit 371 includes two clamping pieces 3711 and a turn button 3713. When the two clamping pieces 3711 are joined, a groove formed thereon defines the slot 3710. The turn button 3713 is used to adjust a joining tightness of the two clamping pieces 3711. For example, when the turn button 3713 is rotated clockwise (or counterclockwise), the joining level of the two clamping pieces 3711 is looser, and the engaging component 315 can be inserted into the slot 3710 at such time. Next, the turn button 3713 is rotated counterclockwise (or clockwise), and the joining tightness of the two clamping pieces 3711 is increased so as to securely sandwich the engaging component 315 in the slot 3710.

In some embodiments, the movable component 37 includes a ring structure 375 having an adjustable level of tightness, wherein the ring structure 375 encircles the second rod 351 and is capable of sliding along a length of the second rod 351.

The training system 100 includes a training device 110 (e.g., the training device 1 or 3), a server 120 and a user device 130. When the training device 110 is configured to perform the related user operations of the foregoing embodiments, a driver (e.g., the driver 1131) of the training device 110 can detect operation data 112 of the training device 110 during an operation process. Next, a controller (e.g., the controller 1133) of the training device 110 can provide the operation data 112 to the server 120 through a network 140 using a transmission unit (not shown) of the training device 110.

Next, the server 120 can determine at least one training data 122 based on the operation data 112. In some embodiments, the operation data 112 can at least include related data such as external force which a user applies to the training device 110, an auxiliary force provided by the training device 110, and an operating range of a rod of the training device 110. According to the operation data 112, the server 120 can determine the training data 122, such as (1) whether the user encounters an obstacle while operating the training device 110, (2) whether a training amount of the user is excessive or inadequate, and (3) whether the training form of the user is appropriate. Next, the server 120 can provide the at least one training data 122 to the user device 130 through the network 140, for the user to determine whether training conditions thereof meet requirements.

It should be noted that, during the process in which the server 120 determines the at least one training data 122 based on the operation data 112, technologies such as big data, artificial intelligence (AI) and machine learning can be used. Specifically, the server 120 can first collect data such as various types of operation data and corresponding training data, and create a determination module based on the data by means of AI and machine learning. Thus, when the server 120 subsequently receives related operation data, the operation data can be input to the determination module to directly acquire the training data.

In some embodiments, the server 120 can determine, based on the training data 122, at least one item 124 corresponding to the training data 122, and provide the at least one item 124 to the user device 130 through the network 140, for the user to refer to the related item 124. For example, when the training data 122 points out that the user may need certain instruction or equipment, the server 120 can determine at least one item 124 (for example, a network link or picture of a course or piece of equipment) satisfying the course or commodity based on the training data 122. Next, the server 120 can provide the at least one item 124 to the user device 130 through the network 140, and the user device 130 can display the training data 122 and the item 124 on a graphical user interface (for example, the graphical user interface shown in FIG. 16B) using a display unit. The item 124 may include a quick response (QR) code.

The terminology used in the description of the present disclosure is for the purpose of describing particular embodiments only, and is not intended to limit the disclosure. As used in the description of the disclosure and the appended claims, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

It shall be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. The use of directional adjectives “above,” “under,” “upper,” “lower,” “below,” “left,” “right,” “up,” “down,” “top,” “bottom,” “vertical,” “horizontal,” and like terms, are meant to assist with understanding relative relationships among design elements and should not be construed as meaning an absolute direction in space nor regarded as limiting. For example, in some embodiments, “a first component is on a second component” describes the first component being on the second component (the first component is directly on the second component), some other components between the first and second components.

Terms such as “approximately,” “substantially,” or “about” are applied to describe a small variation of a structural unit of an apparatus. When a term is used in conjunction with another term to describe a particular characteristic of the claimed disclosure, such term can indicate the exact events or circumstances, and similar exact events or circumstances.

Obviously, numerous modifications and variations of the present disclosure are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the present disclosure may be practiced otherwise than as specifically described herein.
