[0022] The present disclosure will now be described in detail with reference to the drawings illustrating several embodiments of the present disclosure.

[0023] 1a and 1b are respectively a front view and a cross-sectional view of a training device according to some embodiments of the present disclosure. As shown in FIGS. 1a and 1b, the training device according to some embodiments of the present disclosure includes a top member 101, a bottom member 102, and a traction member 103 disposed between the top member 101 and the bottom member 102. The traction member 103 is arranged to be extendable and contractible along the axial direction of the top member 101 or the bottom member 102 to realize relative movement between the top member 101 and the bottom member 102. In the training device according to some embodiments of the present disclosure, the axial extension and contraction of the traction member 103 achieves the purpose of assisting activity of areas requiring activity, such as the neck or joints. For example, the training device according to some embodiments can assist neck activity in healthy individuals or assist the activity of patients with cervical spondylosis to relieve or treat pain. Furthermore, the training device described above has a simple structure, is lightweight, portable, and low-cost, making it suitable for home training and rehabilitation therapy.

[0024] In some embodiments of the training device of the present disclosure, the top and bottom members may be annular structures, and the traction member may be annular structures that fit the top and bottom members, and when the training target area protrudes into the annular structure, an assisting force can be obtained in a state in which the traction member expands and contracts in the axial direction.

[0025] A training device according to some embodiments of the present disclosure may be a training device used for a specific active position of a training subject, such as a training device used for joints of the neck, arms, legs, etc. of a human or animal. In the following description of the present disclosure, a neck training device will be mainly described as an example.

[0026] In some embodiments of the training device according to the present disclosure, the traction member has a plurality of traction sub-members, each of which is arranged to be independently extendable and retractable in the axial direction. Because the traction sub-members are independently controllable, they can adapt to the autonomous activity of the trainee. For example, when the trainee moves in a certain direction, the traction sub-members are each controlled to adapt to the direction of the trainee's movement, thereby enhancing the positive effects of training and reducing the negative effects of training. In some embodiments, the training device according to the present disclosure further includes a top support disposed between the top member and the traction member, and a bottom support disposed between the bottom member and the traction member.

[0027] 1a and 1b, according to some embodiments, the training device further comprises a top support 104 disposed between the top member 101 and the traction member 102 to receive and secure the top member 101, and a bottom support 105 disposed between the bottom member 102 and the traction member 103 to secure the bottom member 102. The traction member 103 may be removably connected between the top support 104 and the bottom support 105.

[0028] 2a to 2e are perspective views each showing a schematic representation of each component of a training device according to some embodiments of the present disclosure.

[0029] 2a-2d are diagrams illustrating a top part 101 and a bottom part 102, respectively, of a training device according to some embodiments of the present disclosure. In some embodiments of the present disclosure, the top part 101 and the bottom part 102 may be flexible members, such as annular airbags, i.e., top and bottom airbags, as shown in FIGS. 2a and 2d. Because the top part 101 and the bottom part 102 must be in direct contact with the trainee (e.g., the human body), using members such as airbags can improve comfort. The top and bottom airbags may be in the form of inflatable airbags. As shown in FIGS. 2a and 2d, the top and bottom airbags may have a toroidal shape like a tire after inflation.

[0030] Because the airbags have a small volume before inflation, the top and bottom airbags of the training device can be kept uninflated before wearing, making them easy to wear, store, and carry; after inflation, the airbags have a certain degree of elasticity and flexibility, making the training device comfortable to wear when operating. Furthermore, because the top airbag has excellent flexibility and toughness when inflated, it makes sufficient contact with the wearer's head to support the weight of the wearer's head and also serves as the direct point of force when traction is performed on the neck. Inflation and deflation of the top and bottom airbags can be performed using an external electric or manual air pump, or can be controlled by a dedicated control device.

[0031] In some embodiments of the present disclosure, as shown in FIG. 2a, the top member 101 is provided with a notch 101a positioned corresponding to the position of the wearer's lower jaw (commonly referred to as the chin) when worn, so as to fit the lower jaw, thereby improving wearing comfort. Also, as shown in FIG. 2a, the top member 101 may further include at least one protrusion 101b positioned to support the wearer's neck and / or head (two protrusions 101b corresponding to the positions of the human shoulders are shown in FIG. 2a). The at least one protrusion 101b is primarily used to contact and support the neck and / or head of the human body when worn, so its structure fits the contours of the corresponding parts of the neck and / or head, further improving wearing comfort. Optionally, when the top member 101 is a circular airbag, the at least one protrusion 101b is an inflatable structure designed integrally with the circular airbag.

[0032] FIG. 2b shows a top support 104 of a training device according to some embodiments of the present disclosure. As shown in FIGS. 2b and 1b, the top support 104 may have a first groove 104c for receiving the top member 101. In some embodiments, the top support 104 may have a notch 104b that fits into the notch 101a of the top airbag 101, as shown in FIG. 2a, that is supported by the top support 104. Optionally, as shown in FIG. 1b, the bottom of the top support 104 may have a first locking groove 104a (not shown in FIG. 2b) for connecting to the traction member 103.

[0033] FIG. 2c shows a bottom support 105 of a training device according to some embodiments of the present disclosure. As shown in FIGS. 2c and 1b, the bottom support 105 may be annular, and a second locking groove 105b for connecting to the traction member 103 is provided at the top thereof. As shown in FIG. 2c, the bottom support 105 may further include a recess 105c for accommodating a connecting member for connecting to an external device. For example, if the device, for example, the top member 101 or the bottom member 102, is an airbag, the recess 105c may accommodate a connecting wire for connecting an inflation pump for inflating the airbag. Furthermore, as shown in FIG. 1b, a lower portion of the bottom support 105 may include a second groove 105d (not shown in FIG. 2c) for accommodating the bottom member 102, similar to the first groove 104c of the top support 104.

[0034] In some embodiments of the training device according to the present disclosure, as shown in Figures 1a and 1b, the first groove 104c of the top support 104 and the second groove 105d of the bottom support 105 may be annular grooves, and their opening directions may be opposite, i.e., the first groove 104c faces upward and the second groove 105d faces downward. The top member 101 and the bottom member 102 may be detachably connected to the top support 104 and the bottom support 105, respectively, by a fastening method. For example, as shown in Figure 1b, if the top member 101 and the bottom member 102 are annular inflatable airbags, in an inflated state, the top member 101 and the bottom member 102 are fastened within the first groove 104c of the top support 104 and the second groove 105d of the bottom support 105, respectively.

[0035] In some embodiments, FIG. 1b As shown in FIG. 1, the first groove 104c in the upper part of the top support 104 Arc shape The inner diameter of the cross section is the same as the outer diameter of the circular cross section of the top member 101, thereby realizing a tight fit between the two. DepthThe value of exceeds the inner diameter value of its circular cross section, and is bent inward at a certain angle on both sides of the tail of the first groove 104c, so that when the top member 101 is in an inflated state, it is more firmly engaged in the first groove 104c of the top support 104 and is integrated so that it does not easily separate, thereby fulfilling the role of fixing the top member 101 to the top support 104.

[0036] In some embodiments, FIG. 1b As shown in FIG. 1, the second groove 105d in the lower part of the bottom support 105 Arc shape The inner diameter of the cross section is the same as the outer diameter of the circular cross section of the bottom member 102, thereby realizing a tight fit between the two. Depth The value of exceeds the inner diameter value of its circular cross section, and both sides of the tail of the second groove 105d are bent inward at a certain angle, so that the bottom member 102 is more firmly engaged in the second groove 105d of the bottom support 105 when in an inflated state, and is integrated in an inseparable manner, thereby playing the role of fixing the bottom member 102 to the bottom support 105.

[0037] In some embodiments, FIG. 1b As shown in Fig. 1, the traction member 103 may be an expandable structure, such as an inflatable laminated structure. The traction member 103 has an upper groove 103a and a lower groove 103b, which are respectively arranged to fit into a first locking groove 104a at the bottom of the top support 104 and a second locking groove 105b at the top of the bottom support 105. Therefore, when connected, the upper groove 103a of the traction member 103 is directly engaged in the first locking groove 104a of the top support 104, and the lower groove 103b of the traction member 103 is directly engaged in the second locking groove 105b of the bottom support 105.

[0038] 2e illustrates a plurality of traction sub-members 1031-1038 of the traction member 103 of a training device according to the present disclosure. In some embodiments, as shown in FIG. 2e, the traction member 103 of the training device can have a plurality of traction sub-members 1031-1038, Multiple Towing sub-members 1031~1038 Each ofmay be independently arranged to be telescopic along the axial direction of the top member 101 or the bottom member 102. As shown in Figures 1a and 2e, the top support 104 and the bottom support 105 are annular structures, and the plurality of traction sub-members 1031-1038 are provided on the bottom support 105 to connect to the top support 104, and the plurality of traction sub-members 1031-1038 are spaced apart in sequence along the annular structure.

[0039] According to the physiological principles of the human body, the movement of the human neck is mainly achieved by the contraction and extension of the musculature distributed around the neck, which completes the multi-degree-of-freedom activity of the human neck. Based on the degrees of freedom of the movement of the human neck and the configuration of the musculature that drives neck movement, the musculature that produces the effect of traction in movement can be simplified to a few major musculature, ignoring the complex and minute musculature. For example, this can be simplified to eight musculature around the neck: the erector spinae muscle located at the rear, the left trapezius muscle located at the rear left, the left sternocleidomastoid muscle located at the left side, the left platysma muscle located at the front left, the sternohyoid muscle located at the front right, the right platysma muscle located at the front right, the right sternocleidomastoid muscle located at the right side, and the right trapezius muscle located at the rear right. Therefore, according to the principles of bionics, Figure 2e The multiple traction sub-members 1031 to 1038, which can be individually stretched and contracted in the axial direction shown in FIG. 1, are arranged to correspond to the positions of different muscle tissues around the neck when worn by the wearer, and by imitating the contraction and extension of each major muscle tissue that brings about the movement traction effect around the neck of the human body, the top member 101 can be driven to complete a multi-directional, multi-angle, and multi-dimensional traction action around the neck of the human body.

[0040] In mathematical and physical terms, "axial direction" typically refers to a cylindrical object, i.e., the direction of the cylinder's central axis of rotation, i.e., the direction common to the central axis. Therefore, "axial movement" refers to movement along the axial direction, i.e., movement along the central axis of rotation. In this disclosure, the top member, bottom member, and traction member are typically annular, as shown in FIG. 2e, to fit the contours of the human neck and head. Therefore, these objects are cylindrical objects with symmetrical centers of rotation. Therefore, the "axial extension and contraction or axial movement" of the traction member or traction sub-member described herein refers to movement along the central axis of rotation of the top member, bottom member, or traction member, i.e., movement along a substantially vertical direction, thereby driving the top member to traction the neck. Generally, the axial extension and contraction movement of each of the multiple traction sub-members 1031-1038 can be performed individually or independently to drive the top member to achieve flexible traction on the neck. Of course, some or all of the plurality of traction sub-members 1031 to 1038 can also cooperate to axially expand and contract so as to achieve diversified cervical traction.

[0041] For example, the traction sub-members 1031-1038 shown in Fig. 2e are arranged to correspond to the erector spinae muscle located immediately behind the neck, the left trapezius muscle located behind the left, the left sternocleidomastoid muscle located on the left, the left platysma muscle located on the left anterior, the sternohyoid muscle located immediately anterior, the right platysma muscle located on the right anterior, the right sternocleidomastoid muscle located on the right, and the right trapezius muscle located on the right posterior, respectively, around the neck as described above, and can mimic the contraction and / or extension movements of the corresponding muscle tissues. The extension and contraction movements of the traction sub-members 1031-1038 can cooperate with each other to realize, for example, at least four degrees of freedom of traction movement, including, but not limited to, forward bending / retroflexion in the sagittal plane, leftward bending / rightward bending in the coronal plane, rotation in the horizontal plane, and vertical extension / traction movement.

[0042] Hereinafter, with reference to FIG. 2e, the principle of realizing a traction operation with multiple degrees of freedom (here, four degrees of freedom is taken as an example) using a plurality of extendable traction sub-members 1031 to 1038 will be described.

[0043] 1. Sagittal plane forward bending / retroflexion movement: The first traction sub-member 1031 corresponding to the erector spinae muscle is extended in the vertical axis direction, while the fifth traction sub-member 1035 corresponding to the sternohyoid muscle is contracted in the vertical axis direction, thereby pushing the top member 101 to perform sagittal plane forward bending movement and driving the wearer's neck to complete the sagittal plane forward bending movement; conversely, the fifth traction sub-member 1035 corresponding to the sternohyoid muscle is extended in the vertical axis direction, while the first traction sub-member 1031 corresponding to the erector spinae muscle is contracted in the vertical axis direction, thereby pushing the top member 101 to perform sagittal plane retroflexion movement and driving the wearer's neck to complete the sagittal plane retroflexion movement.

[0044] 2. Left flexion / right flexion movement in the coronal plane: The third traction sub-member 1033 corresponding to the left sternocleidomastoid muscle is extended in the vertical axis direction, and at the same time, the seventh traction sub-member 1037 corresponding to the right sternocleidomastoid muscle is contracted in the vertical axis direction, thereby driving the wearer's neck to complete the right flexion movement in the coronal plane; conversely, the seventh traction sub-member 1037 is extended in the vertical axis direction, and at the same time, the third traction sub-member 1033 By contracting the arm in the vertical axis direction, the wearer's neck is driven to complete a left flexion movement in the coronal plane.

[0045] Similarly, the fourth traction sub-member 1034 corresponding to the left platysma muscle is extended in the vertical axis direction while the eighth traction sub-member 1038 corresponding to the right trapezius muscle is contracted in the vertical axis direction, thereby realizing right backward flexion of the neck; conversely, the eighth traction sub-member 1038 is extended in the vertical axis direction while the fourth traction sub-member 1034 is contracted in the vertical axis direction, thereby realizing left forward flexion of the neck. Furthermore, the sixth traction sub-member 1036 corresponding to the right platysma muscle is extended in the vertical axis direction while the second traction sub-member 1036 corresponding to the left trapezius muscle is contracted in the vertical axis direction. Sub-member 1032By contracting the second traction sub-member 1032 in the vertical axis direction, the neck of the human body can be bent backward to the left; conversely, by extending the second traction sub-member 1032 in the vertical axis direction and simultaneously contracting the sixth traction sub-member 1036 in the vertical axis direction, the neck of the human body can be bent forward to the right.

[0046] 3. Horizontal plane rotational movement: The first, second, third, fourth, fifth, sixth, seventh, and eighth traction sub-members 1031 to 1038, which correspond to the erector spinae, left trapezius, left sternocleidomastoid, left platysma, sternohyoid, right platysma, right sternocleidomastoid, and right trapezius muscles, respectively, are sequentially extended in the vertical axis direction in a clockwise order, and at the same time, the traction sub-member opposite to the traction sub-member undergoing the extension / contraction movement is contracted in the vertical axis direction. That is, the first pulling sub-member 1031 extends, and at the same time, the opposing fifth pulling sub-member 1035 contracts in the vertical axis direction; the second pulling sub-member 1032 extends, and at the same time, the opposing sixth pulling sub-member 1036 contracts in the vertical axis direction; the third pulling sub-member 1033 extends, and at the same time, the opposing seventh pulling sub-member 1037 contracts in the vertical axis direction; the fourth pulling sub-member 1034 extends, and at the same time, the opposing eighth pulling sub-member 1038 contracts in the vertical axis direction. The fifth traction sub-member 1035 extends, while the opposing first traction sub-member 1031 contracts in the vertical direction; the sixth traction sub-member 1036 extends, while the opposing second traction sub-member 1032 contracts in the vertical direction; the seventh traction sub-member 1037 extends, while the opposing third traction sub-member 1033 contracts in the vertical direction; the eighth traction sub-member 1038 extends, while the opposing fourth traction sub-member 1034 contracts in the vertical direction. In this way, the wearer's neck can be driven to complete a clockwise rotational movement in a horizontal plane. Conversely, by extending the eight traction sub-members 1031 to 1038 in the vertical axis direction in a counterclockwise order while simultaneously contracting the traction sub-member opposite the extending traction sub-member, the wearer's neck can be driven to complete a counterclockwise rotational movement in the horizontal plane.

[0047] 4. Vertical (i.e., axial) stretching and traction movement: The eight traction sub-members 1031 to 1038 are simultaneously stretched in the vertical axial direction, driving the wearer's neck to complete the vertical stretching and traction movement.

[0048] As described above, the training device according to the present disclosure uses a plurality of extendable traction sub-members 1031-1038, each corresponding to a plurality of major muscle tissues that produce a traction effect around the neck, to mimic the contraction and contraction of the corresponding muscle tissues, thereby realizing multi-degree-of-freedom (i.e., multi-angle, multi-directional, multi-dimensional) traction and pulling movements of the neck to achieve the goal of cervical rehabilitation training. The above-mentioned four-degree-of-freedom traction movements are exemplary or predetermined traction movement modes that realize basic traction and stretching of the neck, and users can design multiple personalized traction movement modes according to their needs and actual situations.

[0049] Alternatively, each traction sub-member can be controlled cooperatively or independently. In some embodiments, the control of each traction sub-member can be performed simultaneously or with a time lag between them. In this way, each traction sub-member can cooperate with each other to complete the drive to the top support and the top member, thereby achieving the rehabilitation training task of the user's (i.e., wearer's) neck.

[0050] The training device disclosed herein uses a bionic design and expandable traction member to mimic the neck musculature, thereby achieving traction on the wearer's neck, thereby reducing head pressure on the neck, alleviating neck muscle spasms, increasing the distance between vertebrae, and relieving pressure or irritation on the cervical nerve roots, muscles, and cervical vertebrae, thereby strengthening the neck muscles and treating cervical spondylosis. Furthermore, the cervical spine rehabilitation training device disclosed herein provides comfortable wearing and traction by allowing the top and bottom members to directly contact the neck and / or head and the surrounding skin. Therefore, the training device disclosed herein has advantages such as simple structure, excellent portability and flexibility, comfortable wearing, and low cost, making it suitable for wide application in the field of home rehabilitation medical services.

[0051] 3a-3b show cross-sectional views of traction sub-members of training devices according to some embodiments of the present disclosure in an uninflated state and an inflated state, respectively. The traction sub-members may be inflatable as shown, i.e., expand when inflated and contract when deflated. For clarity, only one traction sub-member 1031 is shown in FIGS. 3a and 3b.

[0052] As shown in FIGS. 3a and 3b, the expandable traction sub-member 1031 may be, for example, an inflatable laminated structure 1031. Each laminated layer in the laminated structure 1031 is stacked along the bottom member toward the top member. The laminated structure 1031 is flat when uninflated and expands when inflated, allowing relative movement between the top and bottom members upon inflation and deflation. The laminated structure 1031 may have an internal cavity. When the internal cavity is uninflated (as shown in FIG. 3a), the laminated structure 1031 is flat. When the internal cavity is inflated (as shown in FIG. 3b), the internal cavity is inflated and pressure increases, causing the laminated structure to expand and elongate vertically, i.e., axially. This generates an axial driving force, which drives the top support and the top airbag to push the wearer's neck and move axially, thereby achieving cervical or cervical spine rehabilitation training. Thus, when an inflatable structure, particularly an inflatable laminate structure 1031, is used as an expandable traction sub-member, axial traction of the neck can be easily achieved by inflating and releasing air. In some embodiments, the length of axial extension of the inflatable laminate structure 1031 can be controlled by controlling the amount of air filled in the laminate structure 1031. Optionally, the number of the plurality of traction sub-members can be 7 to 9, for example, 8 as shown in FIG. 2e. In some embodiments of the present disclosure, the upper and lower ends of the lumen of the laminate structure 1031 extend to the positions of the upper slot 103a and the lower slot 103b, respectively. 1b, in an inflated state, the internal air pressure of the laminated structure 1031 increases, causing the upper and lower ends of the lumen to expand and press against the upper slot 103a and the lower slot 103b on both sides, respectively, causing them to tightly and firmly engage with the wall of the first locking groove 104a of the top support 104 and the wall of the second locking groove 105b of the bottom support 105, thereby achieving tight contact and preventing loosening.More generally, in addition to an expandable structure that is configured by inflation and deflation, the traction sub-member 1031 may also employ a structure that can be expanded and contracted under control based on mechanical principles, such as a spring or a structure similar to a firefighting elevator.

[0053] In some embodiments of the present disclosure, the laminated structures 1031-1038 may be fabricated from rubber tubing, since the low ductility of the rubber tubing can prevent uncontrollable expansion elastic deformation and its toughness can increase its pressure-bearing capacity. Optionally, the laminated structures 1031-1038 may include multiple rubber tubings stacked and communicating with each other.

[0054] In some embodiments of the present disclosure, as shown in FIGS. 3a and 3b, in the laminated structures 1031-1038, the top rubber tube and the bottom rubber tube each have one opening, the rubber tube between the top rubber tube and the bottom rubber tube has two openings, one above the other, and adjacent rubber tubes are connected via adjacent openings.

[0055] In some embodiments of the present disclosure, the top rubber tube and the bottom rubber tube each have two slots 103a, 103b on the side adjacent to the adjacent rubber tube, the two slots 103a, 103b being located on both sides of the opening and extending along the opening direction, and the top support has two slots 103a, 103b on the side adjacent to the rubber tube, the top rubber tube Top slot a first locking groove 104a that fits into and connects with the bottom rubber tube; and a second locking groove 104b that fits into and connects with the bottom rubber tube on the side of the bottom support that is adjacent to the rubber tube. Top slot A second locking groove 105b is provided to fit into 103b.

[0056] In some embodiments of the training device according to the present disclosure, when the traction sub-members 1031-1038 are inflatable laminate structures, each laminate structure 1031-1038 can be connected to an inflating / deflating means (e.g., an air pump) through a plurality of air tubes to inflate and deflate the laminate structure. Here, the air tubes can be air passages for inflating and deflating the inflatable laminate structures 1031-1038. Optionally, as shown in FIG. 2c, outer end portions of the plurality of air tubes can be positioned in recesses 105c of the bottom support 105.

[0057] 4a and 4b are front and side views schematically illustrating the three-dimensional wearing effect of a training device according to some embodiments of the present disclosure. As can be seen from the figures, in some embodiments of the training device according to the present disclosure, the top support and the bottom support may be circular in shape so that the user's neck can enter inside, and may be set to a diameter slightly larger than the size of a human head to make it easier for the user to wear the training device. As shown in FIGS. 4a and 4b, in an inflated state, the notch 101a and the protrusion 101b of the top member 101 fit well around the lower jaw and neck of the human body, making the device comfortable to wear.

[0058] Fig. 5 is a perspective view schematically illustrating a training device according to some other embodiments of the present disclosure. Compared to Fig. 1a, the training device illustrated in Fig. 5 may further include a driving means 200 that controls the axial extension and contraction of the traction member 103. The driving means 200 may be detachably connected to the traction member 103 via, for example, a connecting member 300. Such a detachable connection method allows the traction member 103 and the driving means 200 to be integrally connected only when in use and to be relatively independent when not in use, thereby improving portability.

[0059] 6 is a block diagram showing the hardware configuration of the driving means of a training apparatus according to some embodiments of the present disclosure, with arrows in the diagram indicating signal flow. As shown in FIG. 6, the driving means of a training apparatus according to some embodiments of the present disclosure includes an inflation mechanism 201 arranged to inflate the laminated structure, a plurality of on-off valve pairs 202 arranged to control inflation and deflation of each laminated structure, and a control mechanism 203 for controlling the inflation mechanism 201 and the plurality of on-off valve pairs 202. Each on-off valve pair 202 is connectable to a corresponding laminated structure via a corresponding air pipe and includes an inflation valve 202a and a deflation valve 202b for controlling inflation and deflation of the corresponding laminated structure, respectively.

[0060] 6 , the inflation mechanism 201 may include an air pump 204, an air pocket 205 connected to the exhaust end of the air pump 204 for storing the generated source gas, a first air pressure sensor 206 for detecting the air pressure in the air pocket 205, and an intake valve 207 connected between the exhaust end of the air pocket 205 and the intake end of the pair of on-off valves 202. The intake valve 207 may be automatically controlled by a control mechanism 203 in response to a user's command or may be manually controlled. The inflation mechanism 201 may further include a three-point air set 208 connected between the intake valve 207 and the pair of on-off valves 202 for controlling (reducing) the maximum pressure value of the source gas flowing into the plurality of stacked structures before reaching the pair of on-off valves. In air drive technology, the air three-piece set (FRL) is a combination of three source gas processing elements: a filter (F), a regulator (R), and a lubricator (L), which are used to purify, filter, and reduce the pressure of the source gas to supply the rated source gas pressure. The regulator stabilizes the pressure of the source gas, keeping it constant and reducing damage to the on-off valve 202 when the pressure of the source gas changes suddenly. The filter is used to purify the source gas, filtering out moisture in the compressed air so that the moisture is not absorbed along with the gas. Laminated structure This can avoid intrusion into the

[0061] In some embodiments of the present disclosure, as shown in FIG. 6, the on-off valve pair 202 may further include a second air pressure sensor 202c disposed at the exhaust end of the inflatable valve 202a for detecting the air pressure in the traction member (e.g., the laminated structure) in real time. The control mechanism 203 may include the second air pressure sensor 202c. cDepending on the air pressure detected by the pressure sensor, the pressure sensor may determine whether to turn off the inflatable laminated structure's inflatable valve 202a or the release valve 202b to stop the inflation or release process. For example, first, the limit of the laminated structure's extension or contraction (e.g., the distance of axial extension or contraction) is determined depending on the target traction motion (e.g., traction motion of the neck back and forth, side to side, or up and down). Then, the internal air pressure measured when the laminated structure reaches the limit of extension or contraction is set as the inflation threshold and the release threshold. After the threshold is determined, the internal air pressure determined in real time by the second air pressure sensor 202c during the inflation or release process may be compared with the inflation threshold or the release threshold. If the detected threshold reaches or exceeds the inflation or release threshold, the pressure sensor may turn off the inflatable valve 202a or the release valve 202b to stop the inflation or release process. In this way, the opening and closing of the fill valve 202a and the release valve 202b can be more precisely controlled, thereby allowing the filling and release process to be precisely controlled to avoid excessive or insufficient air pressure within the laminate structure.

[0062] In some embodiments of the present disclosure, as shown in Figure 6, the driving means 200 may further include a memory 210 for storing predetermined operation methods or steps for realizing a predetermined traction action on the neck. By Memory 210 The control unit 202 is configured to control the pair of on-off valves 202 according to the stored predetermined operation method or step for the neck. This allows the user to control the opening and closing of each inlet valve and outlet valve of the on-off valve group according to the predetermined operation method, thereby controlling the inlet and outlet of each traction sub-member, i.e., driving the top member to achieve various predetermined traction movements for the neck. For example, as described above, predetermined traction movements for the neck include forward bending / rearward extension movements in the sagittal plane, leftward bending / rightward bending movements in the coronal plane, rotation movements in the horizontal plane, and vertical extension traction movements.

[0063] In some embodiments of the present disclosure, as shown in FIG. 6 , the driving means 200 may further include a control panel 211 provided on its outer surface for receiving commands from a user. The control mechanism 203 may be configured to control the on-off valve pairs 202 in response to the user's commands. The control panel 211 may include a power switch button for energizing, and may further include a predetermined traction operation selection interface (e.g., a corresponding physical button or a touch panel) connected to the control mechanism 203 and the memory 210 for selecting a predetermined traction operation. Furthermore, the control panel 211 may include individual interfaces (e.g., physical buttons or a touch panel) connected to each on-off valve pair, allowing the user to freely control the contraction and extension of each traction sub-member according to individual needs and achieve personalized traction operations on the cervical region.

[0064] 7 shows the air drive circuit and control principle diagram of a training device according to some embodiments of the present disclosure, where the thick arrow indicates the direction of airflow and the thin solid arrow indicates the flow of signals. As shown in FIG. 7, in the training device according to the present disclosure, the drive means controls the inflation mechanism 201 and the on-off valve pair 202 by the control mechanism 203 to inflate and deflate the traction member 103. The specific operation process of the drive means is, for example, Control mechanismWhen the air pump 204 is turned on by the control mechanism 203, the gas from the air pump 204 first flows into the gas pocket 205 and then reaches the intake valve 207 (which can be considered as the main switch of the air drive circuit system and controls the flow of source gas into the subsequent circuits). For example, when the control mechanism 203 turns on the intake valve 207, the gas flows into the air three-point set 208. The air three-point set 208 reduces the pressure of the source gas and controls the maximum air pressure flowing into the subsequent circuits. After the pressure reduction, the gas reaches a group of on-off valve pairs, i.e., a plurality of on-off valve pairs 202 (including an inlet valve 202a and an outlet valve 202b) corresponding to each of the traction sub-members of the traction member 103. At this time, each on-off valve pair cooperates with each other to control the inlet and outlet of the corresponding traction sub-member, thereby realizing the corresponding traction operation. Furthermore, in the above process, the first and second air pressure sensors 206, 202c respectively detect the air pressure in the air pocket 205 and the traction member 103, and transmit the detected results in real time to the control mechanism 203. The control mechanism 203 can control the opening and closing of the air pump 204 and / or the on-off valve pair 202 accordingly based on the pressure detected by the first and / or second air pressure sensors 206, 202c.

[0065] In some embodiments of the present disclosure, As shown in Figure 7, The drive means may further comprise a silencer 209 disposed at the exhaust end of the air release valve 202b to reduce exhaust noise when the air release valve 202b is opened to vent the traction member 103.

[0066] FIG. 8 shows a physical connection diagram of each component of a training device according to some embodiments of the present disclosure. As shown in FIG. 8, the air pump 204 includes one or more micropumps. To ensure sufficient generation of source gas, the number of micropumps that simultaneously supply gas can be determined according to the flow rate of the gas generated by the micropumps 204. One or more micropumps 204 (two are shown in the figure) can be connected to the air pocket 205 via an air tube and a three-way valve. The air pump 204 may be an electric pump or a manual pump.

[0067] As shown in FIG. 8 , the first air pressure sensor 206 is connected between the micro air pump 204 and the air pocket 205 via a three-way joint to detect the pressure value inside the air pocket 205 in real time. At the same time, a pressure gauge is installed at the end of the air pocket 205 to intuitively display the pressure value of the source gas inside the air pocket 205 to the user. The first air pressure sensor 206 can transmit the detected data to the control mechanism in real time, so that the control mechanism can control the on / off of the air pump 204 based on the pressure value inside the air pocket 205 detected by the first air pressure sensor 206. For example, if the detected pressure value is higher than the upper pressure limit set in the controller, the control mechanism can issue a stop command to stop the operation of the micro pump; on the other hand, if the pressure value is lower than the lower pressure limit set in the controller, the control mechanism can issue a start command to start the operation of the micro pump. The introduction of the first air pressure sensor 206 can control the pressure of the source gas in the air pocket 205 within a relatively reasonable range (between upper and lower limits) to avoid problems caused by excessive or insufficient pressure. For example, if the pressure in the air pocket 205 is too high, it may be unable to withstand and may be destroyed; if the pressure is too low, it may not be enough to drive the extension of the laminated structure.

[0068] In some embodiments of the training device of the present disclosure, the pair of on-off valves 202 may be a group of solenoid valves. Compared to other types of valves, solenoid valves have a more sensitive response, a shorter response time (e.g., as short as several milliseconds), and a relatively fast on-off speed. This allows for rapid adjustment of the gas pressure within the laminated structure, thereby enabling flexible and diverse control of traction movements on the neck and easily realizing relatively complex traction movements, such as rotational movements on a horizontal plane. Furthermore, solenoid valves are highly suitable for use in the portable training device of the present disclosure due to their simple structure, small size, and low power consumption. Of course, the pair of on-off valves 202 may also be a group of motorized valves or other types of actuated valves, as long as they meet the requirements of sensitive (high-speed) control and portability.

[0069] The inlet valve 202a and the outlet valve 202b of the on-off valve pair 202 may be connected to the air passage via a three-way joint, with the inlet end of the inlet valve 202a connected to the inlet mechanism 201 (i.e., the air three-piece set 208) and the outlet end connected to the three-way joint; the inlet end of the outlet valve 202b connected to the three-way joint and the outlet end connected to the outside environment, i.e., the outlet port of the corresponding laminated structure 1031-1038. It should be noted that for clarity, only one on-off valve pair, i.e., one set of inlet valve and outlet valve, is shown in FIGS. 6 and 7. In practice, however, each towing sub-member or laminated structure 1031-1038 can correspond to one on-off valve pair, i.e., one inlet valve and one outlet valve, as shown in FIG. 8. Therefore, the total number of on-off valves is twice the number of laminated structures 1031-1038. For example, Fig. 8 shows eight stacked structures, and the corresponding on-off valve pairs have eight pairs of on-off valves, for a total of 16 single on-off valves, including eight inflating valves and eight releasing valves. The control mechanism individually controls each on-off valve pair in the on-off valve group, and makes them cooperate with each other to inflate or release (i.e., pressurize or depressurize) the corresponding stacked structure, thereby forming axial expansion and contraction, and driving the top airbag to realize multi-degree-of-freedom traction movement of the neck.

[0070] In some embodiments of the present disclosure, as shown in FIG. 8, a silencer 209 is disposed at the exhaust end of the air release valve 202b to reduce exhaust noise when the air release valve 202b is opened to release air from the laminated structures 1031-1038.

[0071] 9 shows an operation flowchart of the training device according to some embodiments of the present disclosure. For the purpose of explanation, eight traction sub-members will be described as an example below, and their positions on the main body structure correspond to the eight muscle tissues around the neck of the human body: the erector spinae muscle located at the rear, the left trapezius muscle located at the rear left, the left sternocleidomastoid muscle located at the left side, the left platysma muscle located at the front left, the sternohyoid muscle located at the front anterior, the right platysma muscle located at the front right, the right sternocleidomastoid muscle located at the right side, and the right trapezius muscle located at the rear right.

[0072] Generally, the operational flow of the training device according to some embodiments of the present disclosure includes the following steps: first, pre-inflate the eight traction sub-members, then extend them to activate the top airbag to support the wearer's head and keep the wearer's neck upright; then, by controlling the inflation and deflation of each traction sub-member, multi-degree-of-freedom traction movements, such as forward and backward bending in the sagittal plane, left and right bending in the coronal plane, rotation in the horizontal plane, and vertical extension traction movements, are realized.

[0073] In one example, as shown in the flowchart of FIG. 9, after a user puts on the training device, in step S901, the user turns on the training device, for example, by triggering a power switch on a control panel.

[0074] Next, in step S902, the control mechanism opens the intake valve of the inflation mechanism. At the same time, in step S902', the control mechanism turns on the air pump; thereafter, the control mechanism controls the on / off of the air pump according to the pressure value Λ in the air pocket detected in real time by the first air pressure sensor. Specifically, in step S903', the control mechanism compares the real-time detected pressure value with a predetermined threshold; if the detected pressure value is greater than the predetermined upper threshold, the control mechanism turns off the air pump in step S904'; if the detected pressure value is less than the predetermined lower threshold, the control mechanism keeps the air pump on to control the pressure in the air pocket within a reasonable range. The upper and lower thresholds can be preset as needed.

[0075] After step S902, the operation flow proceeds to the pre-inflation stage. Specifically, in step S903, the control mechanism controls the on-off valve pairs to turn on all inflation valves and inflate and pressurize the traction sub-member. During the inflation process, in step S904, the second air pressure sensor detects in real time whether the gas pressure inside the traction sub-member reaches a predetermined pre-inflation pressure threshold. If yes, in step S905, the inflation valve is turned off, terminating the pre-inflation stage. If no, the inflation valve is kept on until the predetermined value is reached, and inflation continues. Here, the predetermined value of air pressure used to determine whether the pre-inflation process is complete can be set in the following way: first, the traction sub-member is pre-inflated until the extension of the traction member brings the top member into contact with the wearer's head and holds the wearer's neck in an upright position; then, the pressure value of the gas inside the traction member at this time is measured, and this pressure value is set as the pre-inflation pressure threshold.

[0076] After the pre-inflation is completed, in step S906, the control mechanism can receive a user's input command. For example, the user can input a specific control command through the control panel or touch panel of the driving means. The command can include, for example, a predetermined cervical traction operation mode selected from the memory by the user through a selection interface on the control panel or touch panel, or a specific traction operation specified through an individual interface (e.g., a physical button or touch button) corresponding to each pair of on-off valves arranged on the panel, thereby forming a personalized traction / pulling action on the cervical area. The control command can also include, for example, a command to turn off the training device using a power switch.

[0077] Then, in steps S907 and S907', ​​the control mechanism judges the received user input command and performs different operations according to different commands. First, in step S907, it determines whether the command is to end the cervical training, i.e., to turn off the training device (or power off). If the answer is YES, the operation flow proceeds to end step S911; if the answer is NO, the operation flow proceeds to the next judgment step S907'. In step S907', ​​if the received command is a predetermined traction mode selected by the user, the operation flow proceeds to step S908, where the control mechanism controls the opening and closing of the on-off valve pair based on the specific procedure of the predetermined traction operation stored in memory. If the command is a personalized traction operation input by the user, the operation flow proceeds to step S909, where the control mechanism controls the opening and closing of the on-off valve pair based on the specific operation of each traction sub-component input by the user. In end step S911, the control mechanism controls the on-off valve pair to completely vent each traction sub-component, and turns off the power switch, the main intake valve, and the on-off valve pair.

[0078] After the above-mentioned traction operation step S908 or S909 is completed, the control mechanism proceeds to step S910, where the control mechanism controls the traction sub-member to restore or maintain the pre-filled state, and waits for the next operation command, i.e., proceeds to step S906. Thereafter, the control mechanism determines whether to perform the traction exercise again (S908 or S909) or to completely end the neck training (S911) according to the command input again by the user.

[0079] Hereinafter, using a first traction sub-member corresponding to the erector spinae muscles and its corresponding solenoid valve pair as an example, we will explain how the on-off valve pair inflates and deflates the traction sub-member. The on-off valve pair corresponding to the first traction sub-member includes an inflating valve and a deflation valve, which work together to put the first traction sub-member into one of three states: inflating, holding, or deflation. Specifically, when the inflatable valve is open and the release valve is closed, source gas enters the first retracting sub-member through the inflatable valve, causing the first retracting sub-member to enter a pressurized state and generate an axial biasing force as it extends, pulling the corresponding portion of the neck upward; when the inflatable valve is closed and the release valve is closed, source gas cannot enter the first retracting sub-member and internal gas cannot exit the first retracting sub-member, maintaining the original air pressure within the first retracting sub-member without affecting the neck; when the inflatable valve is closed and the release valve is open, internal gas can escape through the release valve to the outside environment, causing the first retracting sub-member to enter a depressurized state and generate an axial contracting force as it extends, pulling the corresponding portion of the neck downward. Needless to say, the inflatable valve and release valve are never open at the same time. This is because the external source gas flowing in through the inflation valve flows directly out to the external environment through the release valve, which has no effect on the internal pressure of the first traction sub-member and wastes the source gas generated by the inflation mechanism (i.e., the air pump).

[0080] The above describes how pairs of on-off valves are used to inflate and deflate, thereby controlling the expansion and contraction of individual traction sub-members to achieve axial movement. Next, based on the operating principle of the traction members of the training device according to the present disclosure described above with reference to FIG. 2e, we will explain how multiple inflatable traction sub-members cooperate with each other through inflation and / or deflation to achieve multi-DOF traction on the neck. For clarity, the multiple traction sub-members are first to eighth inflatable laminated structures corresponding to the erector spinae muscle located at the rear rear, the left trapezius muscle located at the left rear, the left sternocleidomastoid muscle located at the left rear, the left platysma muscle located at the left front, the sternohyoid muscle located at the front front, the right platysma muscle located at the right front, the right sternocleidomastoid muscle located at the right rear, and the right trapezius muscle located at the right rear, and the top and bottom members are both airbags.

[0081] For example, the training device according to the present disclosure can achieve a four-degree-of-freedom pulling motion as follows.

[0082] First degree of freedom sagittal plane forward bending / retroflexion movement: The first laminated structure is inflated and pressurized to extend it in the axial direction, and at the same time the fifth laminated structure is deflated and depressurized to contract it in the axial direction, thereby pushing the top support and the top airbag to perform sagittal plane forward bending movement, thereby driving the wearer's neck to complete the sagittal plane forward bending movement; conversely, the fifth laminated structure is inflated and pressurized to extend it in the axial direction, and at the same time the first laminated structure is deflated and depressurized to contract it in the axial direction, thereby driving the wearer's neck to complete the sagittal plane retroflexion movement.

[0083] Second degree of freedom: Right flexion / left flexion in the sagittal plane: The third laminated structure is inflated and pressurized to extend it in the axial direction, and at the same time, the seventh laminated structure is deflated and contracted in the axial direction, thereby driving the wearer's neck to complete right flexion in the coronal plane; conversely, the seventh laminated structure is inflated and pressurized to extend it in the axial direction, and at the same time, the third laminated structure is deflated and contracted in the axial direction, thereby driving the wearer's neck to complete left flexion in the coronal plane.

[0084] Third degree of freedom horizontal plane rotational movement: The first to eighth laminated structures are sequentially inflated and pressurized in a clockwise direction, causing them to sequentially extend in the axial direction, and at the same time, the laminated structures opposite to the position of the laminated structure being inflated and pressurized are deflated and caused to sequentially contract in the axial direction, thereby driving the wearer's neck to complete a clockwise rotational movement on the horizontal plane; conversely, the first to eighth laminated structures are sequentially inflated and pressurized in a counterclockwise direction, causing them to sequentially extend in the axial direction, and at the same time, Inflation and pressurization By releasing air and decompressing the laminated structures opposite the central laminated structure position, the laminated structures are caused to contract sequentially in the axial direction, thereby driving the wearer's neck to complete a counterclockwise rotational movement in a horizontal plane.

[0085] Fourth degree of freedom vertical extension: Eight laminated structures can be simultaneously inflated and pressurized, causing them to simultaneously extend in the vertical axis direction, driving the wearer's neck to complete the vertical pulling movement.

[0086] It should be noted that the term "control mechanism" as used herein may include a general-purpose control mechanism (chip) or a single-chip microcomputer that automatically operates by transmitting and receiving signals and calculating and processing information and data. It also includes a drive circuit or other type of drive means (e.g., electric, hydraulic, pneumatic, electromagnetic, etc.) for directly driving corresponding components (e.g., the inflation mechanism and the on-off valve group). For clarity and simplicity, the specification omits these drive means or drive circuits and directly describes the control mechanism controlling each component of the drive means, such as the inflation mechanism and the on-off valve group. The drive means also includes a power source (a fixed power source (commercial power) or a mobile power source (battery)) that supplies power to each component and the drive circuit. If necessary, the power source may also supply power to the drive circuit and the control mechanism via a step-down regulator circuit (transformer).

[0087] Furthermore, the term "detachably connected" as used in this specification refers to connecting two components together by a disassemblable and / or removable connection such as adhesive bonding, fastening, caulking, screwing, interference fitting, etc., and further, the connection between component A and component B can be removed by heating, pulling, pressing, impact, vibration, etc., without destroying and / or damaging component A and component B, thereby facilitating replacement or recycling of the elements.

[0088] Furthermore, in the claims, the use of the verb "comprise" and its conjugations does not exclude the presence of elements or steps not stated in the claims. The word "a" or "an" does not exclude a plurality.
