Abstract
Description
Technical Field
[0001] This invention relates to the field of human exercise training equipment technology, and in particular to a head-mounted training device for resistance training of neck muscles. Background Technology
[0002] The neck muscles are crucial functional units for maintaining head and neck posture stability, ensuring cervical spine biomechanical balance, and performing various head movements. Targeted neck resistance training is of significant value in improving neck muscle strength and endurance, preventing cervicogenic injuries, and assisting in rehabilitation therapy.
[0003] Currently, neck muscle training methods mainly include bodyweight training and machine training. While bodyweight training is simple and easy to perform, it is difficult to accurately quantify the load, and the training intensity and mode are relatively monotonous, resulting in a bottleneck in training effectiveness. Therefore, various neck training machines have emerged. Existing machine designs are mostly based on external frames or seat structures, requiring users to sit or lie on the machine, connecting their head to movable parts, and using resistance sources such as weights, springs, or elastic bands to provide the load. These devices are usually large, lack portability, and are difficult to use in everyday settings such as homes and offices. More importantly, their structural design often results in a relatively fixed direction of training resistance, or relies on the user's shoulders, back, or even the entire torso as a counterforce support point, which may lead to unnatural training movements and potentially generate unexpected axial forces on the cervical spine during training, posing certain safety hazards, especially unsuitable for people with existing cervical spine discomfort or those in the recovery period. Summary of the Invention
[0004] The purpose of this invention is to provide a head-mounted training device for resistance training of neck muscles, in order to solve the problems existing in the prior art and improve the safety of the training process.
[0005] To achieve the above objectives, the present invention provides the following solution: This invention provides a head-mounted training device for resistance training of neck muscles, comprising: Head fixation component for establishing a stable connection with the user's head; The inner ring assembly is disposed around the outside of the head fixing assembly; A vertical swing mechanism is disposed between the head fixing component and the inner ring component, enabling the inner ring component to rotate relative to the head fixing component within a limited angle range about the horizontal axis. An outer ring assembly is sleeved on the inner ring assembly, the inner ring assembly and the outer ring assembly being coaxial; a rotating mechanism is provided between the inner ring assembly and the outer ring assembly, the rotating mechanism enabling the outer ring assembly to rotate relative to the inner ring assembly about the axis of the inner ring assembly; and The elastic resistance assembly includes at least one elastic cord, one end of which is connected to the outer ring assembly and the other end is used to connect to an external fixing point.
[0006] Preferably, the vertical swing mechanism includes two swing units symmetrically distributed on both sides of the head fixing assembly. Each swing unit includes a fixed shaft, a fixed block, a mounting groove, and an arc-shaped slide groove. The fixed shaft is fixedly connected to the head fixing assembly, the fixed block is fixed to the side wall of the fixed shaft, and the mounting groove and the arc-shaped slide groove are both disposed on the inner wall of the inner ring assembly. The fixed shaft is rotatably engaged with the mounting groove, and the fixed block is slidably engaged with the arc-shaped slide groove. The fixed shafts in the two swing units are coaxial, and the arc-shaped slide grooves in the two swing units are directly opposite each other.
[0007] Preferably, when the head-mounted training device is in use, the axial direction of the fixed axis is the same as the coronal axis direction of the user.
[0008] Preferably, the central angle corresponding to the arc-shaped groove is 35°; the swing angle of the inner ring assembly relative to the head fixing assembly in the direction of the user's forward tilt is between 0° and 20°, and the swing angle of the inner ring assembly relative to the head fixing assembly in the direction of the user's backward tilt is between 0° and 15°.
[0009] Preferably, the rotating mechanism includes an annular insertion portion, an upper annular groove, a lower annular groove, and a rolling support structure; The annular insertion part is disposed on the outer side wall of the inner ring assembly. The upper annular groove, the annular insertion part, and the lower annular groove are distributed sequentially from top to bottom and are all coaxial with the inner ring assembly. The opening of the upper annular groove faces downward and communicates with the annular insertion part, and the opening of the lower annular groove faces upward and communicates with the annular insertion part. The rolling support structure includes a support ring, a plurality of upper rollers rotatably mounted above the support ring, and a plurality of lower rollers rotatably mounted below the support ring. The support ring is coaxial with the outer ring assembly and fixedly connected to the outer ring assembly. The support ring portion passes through the annular insertion part. All the upper rollers are evenly distributed along the circumference of the support ring, and all the lower rollers are evenly distributed along the circumference of the support ring. All the upper rollers are located in the upper annular groove and roll in cooperation with the sidewall of the upper annular groove, and all the lower rollers are located in the lower annular groove and roll in cooperation with the sidewall of the lower annular groove.
[0010] Preferably, the axial direction of the outer ring assembly, the axial direction of each of the upper rollers, and the axial direction of each of the lower rollers are parallel to each other.
[0011] Preferably, a plurality of mounting shafts are fixedly provided on the support ring, with some of the mounting shafts located above the support ring and some located below the support ring. The mounting shafts, the upper rollers, and the lower rollers correspond one-to-one, and the upper rollers and lower rollers are respectively mounted on the corresponding mounting shafts.
[0012] Preferably, both the upper roller and the lower roller are made of ball bearings.
[0013] Preferably, the head fixation assembly includes: A head fixation frame, wherein a notch is provided on the head fixation frame and the outline of the notch matches the shape of the human head. A head strap for securing the headrest frame to the user's head; and The fitting buffer component is located on the side of the head fixing frame that contacts the head.
[0014] Preferably, the fitting cushioning assembly includes an inflatable airbag.
[0015] The present invention achieves the following technical effects compared to the prior art: This invention relates to a head-mounted training device for neck muscle resistance training. It integrates head fixation, motion guidance, and resistance application into a single head-mounted device, eliminating the need for a large external frame or fixed seat. This significantly improves portability, allowing neck resistance training to be conveniently performed in various everyday settings such as home and office, overcoming the dependence of traditional equipment on specific training locations. Through the combination of a head fixation component, an inner ring component, and an outer ring component, and the separate installation of a vertical swing mechanism and a rotation mechanism, mechanical decoupling of head tilting and circumferential rotation is achieved. This allows users to obtain pure and targeted resistance when performing unidirectional neck movements (such as simple head turning or simple nodding), avoiding impure movements and muscle compensation caused by multi-degree-of-freedom coupling, resulting in more scientific and efficient training.
[0016] The tension generated by the elastic resistance component is converted into pure torque acting on the head fixation component through the 360° rotatable outer ring component and the rotational connections between the components. This allows the training resistance to act directly on the head in a rectangular force pattern, avoiding axial traction or compression forces on the cervical spine and fundamentally eliminating the risk of cervical spine injury caused by improper axial load. Simultaneously, the arc-shaped groove in the vertical swing mechanism, in conjunction with the fixing block, effectively limits the range of head tilting and lowering, preventing excessive backward tilting or forward flexion, further ensuring the controllability and safety of the training process, especially suitable for individuals with weak neck muscles or those in the rehabilitation phase. Using elastic ropes as the resistance source is not only simple in structure and low in cost, but also allows for convenient and continuous adjustment of the training load by changing elastic ropes with different tensions or adjusting their extension length. Furthermore, because the outer ring component can rotate freely, the connection direction of the elastic ropes is unrestricted, adapting to changes in head position under different movement trajectories. This ensures that the resistance direction is always opposite to the movement trend, simulating a biomechanical environment closer to the natural stress on the neck, resulting in a more natural and fluid training experience. The coaxial nesting design of the inner and outer ring components, along with the integrated swing and rotation mechanism, makes the overall device compact and lightweight. The head fixation component uses a frame that matches the shape of the head and is equipped with an adjustable fixation strap and a fitting cushioning component (such as an inflatable airbag), which can adapt to different head shapes. While ensuring stable fixation, it effectively distributes pressure and improves the comfort of wearing it for a long time. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] The purpose of this invention is to provide a head-mounted training device for resistance training of neck muscles, so as to solve the problems existing in the prior art and improve the safety and controllability of the training process.
[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0022] like Figures 1 to 8 As shown, this embodiment provides a head-mounted training device for resistance training of neck muscles, comprising: Head fixation component for establishing a stable connection with the user's head; Inner ring component 20 is arranged around the outside of the head fixing component; A vertical swing mechanism is provided between the head fixing component and the inner ring component 20, so that the inner ring component 20 can rotate relative to the head fixing component about the horizontal axis within a limited angle range; An outer ring assembly 30 is sleeved on an inner ring assembly 20, and the inner ring assembly 20 and outer ring assembly 30 are coaxial. A rotating mechanism is provided between the inner ring assembly 20 and the outer ring assembly 30, which allows the outer ring assembly 30 to rotate relative to the inner ring assembly 20 about the axis of the inner ring assembly 20. The elastic resistance assembly includes at least one elastic cord (not shown in the figure), one end of which is connected to the outer ring assembly 30 and the other end is used to connect to an external fixing point.
[0023] This embodiment of the head-mounted training device for neck muscle resistance training integrates head fixation, motion guidance, and resistance application functions into a single head-mounted device. It eliminates the need for a large external frame or fixed seat, greatly improving portability and allowing neck resistance training to be conveniently performed in various everyday settings such as home and office, breaking through the dependence of traditional equipment on specific training locations. Through the combination of the head fixation component, inner ring component 20, and outer ring component 30, and the separate installation of vertical swing and rotation mechanisms, mechanical decoupling of head tilting and circumferential rotation is achieved. This allows users to obtain pure and targeted resistance when performing single-direction neck movements (such as simple head turning or simple nodding), avoiding impure movements and muscle compensation caused by multi-degree-of-freedom coupling, making training more scientific and efficient.
[0024] In an optional embodiment, a preferred embodiment is a vertical swing mechanism comprising two swing units symmetrically distributed on both sides of the head fixing assembly. Each swing unit includes a fixed shaft 101, a fixed block 102, a mounting groove 203, and an arc-shaped slide 204. The fixed shaft 101 is fixedly connected to the head fixing assembly, the fixed block 102 is fixedly mounted on the side wall of the fixed shaft 101, and the mounting groove 203 and the arc-shaped slide 204 are both disposed on the inner wall of the inner ring assembly 20. The fixed shaft 101 is rotatably engaged with the mounting groove 203, and the fixed block 102 is slidably engaged with the arc-shaped slide 204. The fixed shafts 101 in the two swing units are coaxial, and the arc-shaped slides 204 in the two swing units are directly opposite each other.
[0025] In the optional embodiments of this example, it is more preferred that when the head-mounted training device is used, the axial direction of the fixed shaft 101 is the same as the coronal axis of the user; since the inner ring assembly 20 rotates relative to the head fixation assembly with the fixed shaft 101 (i.e., the aforementioned horizontal axis) as the central axis, the relative rotation between the inner ring assembly 20 and the head fixation assembly is a rotation along the user's tilt direction. This allows the user to perform tilt movements of the head within a limited angle range when wearing the head-mounted training device for neck muscle resistance training in this embodiment, and the range of tilt movements is limited by the fixed block 102 and the arc-shaped slide 204. Related to the sliding mechanism, when the fixed block 102 moves to the end of the arc-shaped slide 204, the arc-shaped slide 204 will limit the fixed block 102, so that the fixed block 102 can no longer slide. The angle range in which the fixed block 102 can slide along the arc-shaped slide 204 is the rotation angle range of the inner ring component 20 relative to the head fixing component. By reasonably designing the size of the central angle of the arc-shaped slide 204 and the size of the fixed block 102, the required limited angle range can be achieved to effectively limit the amplitude of head tilting and head lowering, prevent excessive backward tilting or forward flexion, and further ensure the controllability and safety of the training process.
[0026] In one optional embodiment, the central angle of the arc-shaped slide 204 is 35°; the swing angle of the inner ring assembly 20 relative to the head fixing assembly in the direction of the user's forward tilt is between 0° and 20°, and the swing angle of the inner ring assembly 20 relative to the head fixing assembly in the direction of the user's backward tilt is between 0° and 15°.
[0027] In the optional embodiments of this example, the rotating mechanism preferably includes an annular insertion part 206, an upper annular groove 205, a lower annular groove 207, and a rolling support structure. The annular insertion part 206 is disposed on the outer side wall of the inner ring assembly 20. The upper annular groove 205, the annular insertion part 206 and the lower annular groove 207 are distributed from top to bottom and are all coaxial with the inner ring assembly 20. The opening of the upper annular groove 205 faces downward and communicates with the annular insertion part 206, and the opening of the lower annular groove 207 faces upward and communicates with the annular insertion part 206. The rolling support structure includes a support ring 301, multiple upper rollers 302 rotatably mounted above the support ring 301, and multiple lower rollers 304 rotatably mounted below the support ring 301. The support ring 301 is coaxial with the outer ring assembly 30 and fixedly connected to the outer ring assembly 30. Part of the support ring 301 is inserted into the annular insertion part 206. All the upper rollers 302 are evenly distributed along the circumference of the support ring 301, and all the lower rollers 304 are evenly distributed along the circumference of the support ring 301. All the upper rollers 302 are located in the upper annular groove 205 and roll in cooperation with the side wall of the upper annular groove 205, and all the lower rollers 304 are located in the lower annular groove 207 and roll in cooperation with the side wall of the lower annular groove 207.
[0028] In this embodiment, to facilitate the insertion of the support ring 301 into the annular connector 206, the inner ring assembly 20 is divided into upper and lower parts, namely an upper inner ring 201 and a lower inner ring 202. The annular connector 206 is divided into two completely symmetrical parts, one part located on the upper inner ring 201 and the other part located on the lower inner ring 202. The upper inner ring 201 and the lower inner ring 202 are detachably connected by bolts or snap-fit. During installation, the lower inner ring 202 is first placed on the support ring 301. Below, the upper inner ring 201 is placed above the support ring 301 and aligned with the lower inner ring 202. The upper inner ring 201 and the lower inner ring 202 are then connected together, ensuring that all the lower rollers 304 are embedded in the lower annular grooves 207 on the lower inner ring 202, while all the upper rollers 302 are embedded in the upper annular grooves 205 on the upper inner ring 201. This forms a complete rotating mechanism, allowing the outer ring assembly 30 and the inner ring assembly 20 to rotate relative to each other in a 360° circumferential direction.
[0029] In the optional embodiments of this example, it is preferred that the axial direction of the outer ring assembly 30, the axial direction of each upper roller 302, and the axial direction of each lower roller 304 are parallel to each other; in other optional embodiments, the axial direction of each upper roller 302 and the axial direction of each lower roller 304 can also be along the radial direction of the outer ring assembly 30, which can also achieve the purpose of rolling support.
[0030] In one optional embodiment, a plurality of mounting shafts 303 are fixedly provided on the support ring 301. Part of the mounting shafts 303 are located above the support ring 301, and part are located below the support ring 301. The mounting shafts 303, the upper roller 302, and the lower roller 304 correspond one-to-one. The upper roller 302 and the lower roller 304 are respectively mounted on the corresponding mounting shafts 303. One mounting shaft 303 passes through the support ring 301 and fixes the upper and lower rollers. This ensures that the rotation centers of the upper and lower rollers 304 are strictly aligned in the axial (vertical) direction. This makes the force applied by the outer ring assembly 30 to the upper and lower annular grooves 207 of the inner ring assembly 20 through the rollers collinear and symmetrical. This effectively avoids additional bending moment or jamming caused by misalignment of the upper and lower support points and ensures pure rolling and high smoothness of the rotational motion.
[0031] In the optional embodiments of this invention, it is preferred that both the upper roller 302 and the lower roller 304 employ ball bearings. As a mature standard component, the rolling friction of ball bearings is far less than the sliding friction. Applying them to the upper and lower rollers 304 minimizes the rotational resistance of the outer ring assembly 30 relative to the inner ring assembly 20. During neck lateral flexion or rotation training movements, the change in the direction of the elastic rope can instantly and smoothly drive the outer ring to rotate, avoiding unexpected lateral forces or torsional torques caused by rotational jamming. This fundamentally eliminates the potential safety hazards to the cervical spine that traditional equipment may pose. The ball bearings effectively withstand radial loads and convert sliding friction into rolling friction, greatly reducing wear between the support ring 301 and the groove sidewall of the inner ring assembly 20. This ensures that the rotation mechanism maintains its initial accuracy in terms of movement trajectory and smoothness even after long-term, repeated use, ensuring consistent training results and extending the device's lifespan.
[0032] In the optional embodiments of this example, a preferred embodiment includes: A head fixation frame 10 is provided with a gap, the outline of which matches the shape of the human head. A head strap (not shown) is used to secure the head support frame 10 to the user's head; and The fitting cushioning component is located on the side of the head fixation frame 10 that contacts the head.
[0033] The head strap serves to achieve a stable connection between the head fixation frame 10 and the user's head, thereby ensuring the stability of the head fixation frame 10. The head strap is an existing component familiar to technicians, so its specific structure and working principle will not be elaborated in this embodiment.
[0034] In the optional solutions of this embodiment, the preferred option is that the fit and cushioning component includes an inflatable airbag 103. The fit and cushioning component improves the adaptability of the head fixation frame 10 to different head shapes of users, ensures stable fixation, and can effectively distribute pressure, thereby improving the comfort of wearing for a long time.
[0035] The specific working principle of the head-mounted training device for neck muscle resistance training in this embodiment is as follows: First, the user secures the head strap, puts the head-fixing frame 10 on the head stably, and adjusts the air pressure of the inflatable airbag 103 until the user feels comfortable wearing it. Then, fix the end of the elastic rope in the elastic resistance assembly away from the outer ring assembly 30 to an external fixing point. This external fixing point needs to be stable, such as some sturdy heavy objects or furniture, or of course, it can be a wall or column, as long as it can satisfy the stable fixing of the end of the elastic rope away from the outer ring assembly 30. When the user performs a forward or backward flexion movement, the head drives the head fixation component to move, which in turn drives the inner ring component 20 to oscillate relative to the head with the coronal axis as the axis, within the angle range (such as 0-20° forward flexion and 0-15° backward flexion) defined by the arc-shaped slide 204 through the vertical swing mechanism (specifically, the fixed shaft 101 rotates in the mounting groove 203 while the fixed block 102 slides in the arc-shaped slide 204). When the user performs movements involving horizontal rotation, such as lateral flexion or rotation, the head movement is transmitted to the rotation mechanism through the swinging inner ring assembly 20. At this time, the support ring 301 fixed to the outer ring assembly 30 drives the upper roller 302 and lower roller 304 on it to roll in the upper annular groove 205 and lower annular groove 207 of the inner ring assembly 20, respectively, so that the outer ring assembly 30 can rotate freely and with low resistance relative to the inner ring assembly 20 about its axis (approximately perpendicular to the horizontal plane). Regardless of the type of compound head movement, the outer ring component 30 can adjust its position in real time through the aforementioned combination of swinging and rotation, so that the tension of the elastic rope can always be applied adaptively in the direction roughly opposite to the head movement. This provides the neck muscles with a direct, primarily resistance-based load that matches the direction of movement, while greatly avoiding the harmful lateral forces that may be generated by fixed equipment. This achieves safe, multi-dimensional resistance training that conforms to physiological movement patterns.
[0036] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
