Description

Technical Field

[0001] The utility model relates to the technical field of balance beams, and more specifically, to a dynamic balance beam and a training system. Background Art

[0002] The core part of the human body is an integrated whole formed by the waist, pelvis, and hip joints, which is the middle link of the human body. The core part is an integrated tension system composed of bones, joints, muscles, fascia, etc. When abnormalities occur in some components or regions of the core part, body posture abnormalities caused by core part abnormalities will occur, such as uneven shoulders and changes in the normal physiological curvature of the spine. If these body posture abnormalities further evolve, they will form diseases, such as humpback, lumbar spondylolisthesis, scoliosis, etc. Core stability is a body posture in which the human body creates a fulcrum for the exertion of limb muscles through the stability of the core part during movement, creates conditions for the transmission of upper and lower limb forces, and provides power for the stability and movement of the center of gravity. When core stability weakens, it will cause other parts of the body to compensate, and even cause a series of physical health problems. The force that constitutes or improves stability is core strength. The biggest difference between core strength training and traditional abdominal and lumbar strength training is that core strength training is often carried out under unstable conditions in many cases, which can enable specific muscles, or more small muscle groups, especially the auxiliary muscles around the joints, to participate in the movement, and cultivate the ability of the human body to stabilize joints and control the center of gravity during movement. These small muscle groups around the joints are rarely consciously called by humans in daily life and need special devices to create instability and induce and activate them through certain specific postures and movements.

[0003] The balance ability can be divided into static balance ability and dynamic balance ability. The static balance ability refers to the ability to maintain balance in a static state, such as the balance state when standing on one foot. The dynamic balance ability refers to the ability to maintain balance and control the body during movement.

[0004] The normal orientation of the human body in space and the maintenance of body balance depend on the mutual cooperation of vision, proprioceptors, and the vestibular analyzer, and are completed under the overall decision-making of the brain. At present, the training to improve orientation and balance ability often adopts means such as selecting fixed reference objects, reducing the support surface, standing on one foot, closing eyes, and using balance boards, BOSU balls, and air cushions. Taking the balance beam as an example, in the prior art, usually the balance board and the balance beam can be shaken and swayed to achieve the effect of creating instability.

[0005] In the existing balance beams that can be shaken or swayed, the amplitude of their swaying cannot be adjusted, and no feedback information for proprioceptors and vision is provided. Furthermore, different training programs cannot be formulated according to different people, or the needs of the same person in different training stages cannot be met. Summary of the Utility Model

[0006] The purpose of the present utility model is to overcome the deficiencies of the prior art and provide a dynamic balance beam that can steplessly adjust the swinging amplitude according to the needs of users and provide feedback information in terms of proprioception and vision. Therefore, it can meet the needs of different groups of people or the needs of the same person at different training stages, making the training more in line with the principle of gradual progress. Moreover, the adjustment is convenient and fast, and no external tools are required, making it easy to use.

[0007] To solve the above technical problems, the technical solution adopted by the present utility model is:

[0008] Provide a dynamic balance beam, including a main body, an arc module, and a plurality of support foot components. The arc module is installed at the bottom of the main body, and the arc-shaped structure side of the arc module is located on the side away from the main body. The support foot components pass through the arc module and are threadedly connected to the arc module. Two of the support foot components form a group, and the two support foot components in each group are respectively located on both sides of the central axis of the main body.

[0009] The arc module provides instability for the main body. The arc module is a support member with a flat end at one end and an arc structure at the other end. The present utility model adds an arc module to the basis of an ordinary static balance beam to make it a dynamic balance beam, increasing the requirement for the balance ability of the trainer. Due to the center of gravity of the arc module shifting under force, it causes swaying, which in turn drives the main body to swing. By using the different heights of the support foot components relative to the ground, the swaying amplitude can be interfered with. Specifically, when the bottom of the support foot component is completely in contact with the ground, the dynamic balance beam loses its dynamic function and becomes a static balance beam, which is suitable for beginners to conduct balance training with a relatively low difficulty. Of course, the dynamic balance beam can also be changed into a static balance beam by detachably connecting the arc module to the main body, such as connecting by screws, etc., and inverting the arc module so that its flat end is in contact with the ground. However, compared with this, the scheme of adjusting the height of the support foot component is more simple and fast. As the training intensity increases, the swaying amplitude of the arc module after being stressed can be adjusted by changing the height of the support foot component from the ground, thereby increasing the training difficulty. In the extreme state, when the support foot component is completely placed inside the arc module and does not protrude from its bottom, the maximum swaying amplitude of the dynamic balance beam can be achieved, and at this time, the support foot component will not interfere with the swaying of the arc module. The present utility model can achieve stepless adjustment of the swaying amplitude of the balance beam from zero to the maximum swinging angle by adjusting the height of the support foot component from the ground, and the adjustment is simple and convenient, without the need to disassemble and assemble the whole, which can meet the training difficulty requirements of different users.

Each sensor is communicatively connected to the data processing unit, and the data processing unit is communicatively connected to the display device.

[0057] The sensor data installed on the balance beam is recorded and transmitted to the data processing unit, which further analyzes the change process and provides visual and acoustic prompts. For example, it is further displayed on a display device. When using the balance beam, the user can directly view the display device or its exercise situation and its own situation without using the feedback device. The corresponding processing unit and display device can directly analyze the stability of the balance beam and even convert it into a score value to provide feedback to the user. The virtual balance beam can be directly displayed in the display device, and the sensor parameters can be synchronized to the virtual balance beam. In order to allow the user to feel the instability of balance in reality, the instability of the balance beam can also be visually felt in the virtual scene. Combined with the balance beam in virtual reality, the game interaction is increased, thereby increasing the linkage of hearing, vision, proprioceptors, and vestibular analyzers, increasing neuromuscular recording, and achieving better core muscle training effects.
