TECHNICAL FIELD

[0001] The present application belongs to the technical field of rehabilitation equipment, and particularly relates to a sports rehabilitation apparatus based on waist exercise. BACKGROUND

[0002] With the improvement of the national fitness consciousness and the in-depth development of rehabilitation medicine, as a key component of the core area of the human body, the strength, endurance and flexibility of the muscle group of the waist are of great significance to maintain the stability of the spine, prevent acute and chronic injuries and improve the sports performance.

[0003] The physiological movement of the waist of the human body is a complex three-dimensional movement, mainly including three basic degrees of freedom of "flexion and extension" (forward bending and backward bending) in the sagittal plane, "lateral flexion" (left and right bending) in the coronal plane and "rotation" (left and right rotation) in the horizontal plane. Each movement mode is completed by different muscle groups, for example, the rectus abdominis and erector spinae dominate flexion and extension, the internal and external oblique abdominis and quadratus lumborum dominate lateral flexion, and rotation is deeply dependent on the internal and external oblique abdominis.

[0004] The existing waist twisting device can only provide a composite and rotation-based swinging movement, and cannot separate and accurately control the above three basic movements. This leads to a significant reduction in training effect, and users cannot target their weaknesses for reinforcement. For users who need precise rehabilitation, this training method may even cause secondary injury risk due to non-standard movements.

[0005] Therefore, a new type of waist training device is needed to break through the bottleneck of the prior art. SUMMARY

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0020] In traditional lumbar exercise and rehabilitation settings, existing lumbar exercise equipment is relatively limited in function, mostly only allowing for single-directional lumbar movements, such as forward and backward flexion and extension or lateral flexion. It fails to comprehensively simulate the multi-dimensional movements required by the human lumbar region during daily activities and rehabilitation. This makes it difficult for users to conduct comprehensive and systematic training of the lumbar region during rehabilitation exercises, resulting in insufficient stimulation and exercise of the lumbar muscles and joints, thus affecting the rehabilitation effect and overall functional recovery. Furthermore, single-directional exercise may lead to uneven development of lumbar muscle strength, increasing the risk of lumbar re-injury.

[0021] like Figs. 1-3 As shown, a lumbar exercise rehabilitation device includes a rotating mechanism, a backrest mechanism 2, and a seat cushion mechanism 1. The rotating mechanism connects the backrest mechanism 2 and the seat cushion mechanism 1. The rotating mechanism includes a first rotating shaft 3 and a second rotating shaft 4. The first rotating shaft 3 is mounted on the seat cushion mechanism 1, and the second rotating shaft 4 is rotatably mounted on the first rotating shaft 3. The backrest mechanism 2 is connected to the second rotating shaft 4. The axes of the first rotating shaft 3 and the second rotating shaft 4 are perpendicular. The first rotating shaft 3 is used to realize the forward and backward flexion and extension movements of the backrest mechanism 2 and the seat cushion mechanism 1. The second rotating shaft 4 is used to realize the left and right lateral flexion movements of the backrest mechanism 2 and the seat cushion mechanism 1. When the user needs to perform the forward and backward flexion and extension of the waist, the first rotating shaft 3 mainly plays a role. The user sits on the cushion mechanism 1, the back leans against the back plate mechanism 2, and the back plate mechanism 2 is swung forward and backward with the first rotating shaft 3 as the rotation center by the force of the waist. In this process, the second rotating shaft 4 rotates around the first rotating shaft 3 with the back plate mechanism 2, but since the second rotating shaft 4 does not actively participate in the rotation control at this time, it only follows the back plate mechanism 2 to make the overall forward and backward movement as an intermediate part connecting the back plate mechanism 2 and the first rotating shaft 3. For example, when the user leans forward, the back plate mechanism 2 drives the second rotating shaft 4 to rotate forward around the first rotating shaft 3; when the user leans back, the back plate mechanism 2 drives the second rotating shaft 4 to rotate backward around the first rotating shaft 3, thereby realizing the forward and backward flexion and extension exercise of the waist.

[0022] When the user needs to perform the left and right lateral flexion of the waist, the second rotating shaft 4 begins to play a key role. Similarly, the user sits on the cushion mechanism 1, the back leans against the back plate mechanism 2, and the back plate mechanism 2 is swung left and right with the second rotating shaft 4 as the rotation center by the lateral force of the waist. At this time, the first rotating shaft 3 remains stable as a fixed support for the position of the cushion mechanism 1 and itself, and does not participate in the rotation in the left and right directions. For example, when the user bends to the left, the back plate mechanism 2 drives the second rotating shaft 4 to rotate left around its own axis; when the user bends to the right, the back plate mechanism 2 drives the second rotating shaft 4 to rotate right around its own axis, thereby realizing the left and right lateral flexion exercise of the waist.

[0023] In summary, the embodiment realizes the forward and backward flexion and extension movement of the back plate mechanism 2 and the cushion mechanism 1 by the first rotating shaft 3 and the second rotating shaft 4 which are perpendicular to each other in the rotating mechanism, and realizes the left and right lateral flexion movement by the second rotating shaft 4, so that the user can perform the forward and backward and left and right waist movements on the same equipment, fully simulates the multi-dimensional daily activities, comprehensively trains the waist muscles and joints, effectively improves the rehabilitation effect and overall functional recovery, and balances the development of the muscle groups in different directions of the waist, enhances the stability and support of the waist, and reduces the probability of re-injury.

[0024] In an embodiment, the impedance mechanism 6 is further included, and the impedance mechanism 6 is used to generate resistance when the back plate mechanism 2 rotates; the impedance mechanism 6 includes a support plate 61 and a support shaft 63, the support plate 61 is connected with the cushion mechanism 1, the support shaft 63 penetrates through the support plate 61, the top of the support shaft 63 is hinged with the back plate mechanism 2, an impedance piece 62 is coaxially arranged with the support shaft 63, and the support plate 61 is provided with a mounting portion, and the impedance piece 62 is located in the mounting portion.

[0025] When the user starts to perform the forward and backward flexion and extension of the waist, the back plate mechanism 2 swings forward and backward around the first rotating shaft 3. Since the top of the support shaft 63 is hinged to the back plate mechanism 2, the forward and backward movement of the back plate mechanism 2 will make the support shaft 63 have a corresponding upward and downward movement trend. When the back plate mechanism 2 swings backward, the support shaft 63 will have a downward movement trend, and the impedance element 62 will be compressed to generate an upward resistance. This resistance will hinder the downward movement of the support shaft 63, and further hinder the forward and backward flexion and extension of the back plate mechanism 2. Similarly, when the back plate mechanism 2 swings forward, the support shaft 63 will have an upward movement trend, and the impedance element 62 will be stretched, which also hinders the backward flexion of the back plate mechanism 2.

[0026] In an embodiment, the impedance mechanism 6 includes at least three groups, which are equidistantly arranged at the bottom of the back plate mechanism 2. When the user sits on the cushion mechanism 1 and prepares to perform the left lateral flexion of the waist, the user will twist the waist to the left to exert an external force on the back plate mechanism 2. The external force is transmitted to the support shaft 63 through the hinge point of the back plate mechanism 2 and the support shaft 63, so that the support shaft 63 has a tendency to tilt to the left relative to the support plate 61. Since the three groups of impedance mechanisms 6 are equidistantly arranged at the bottom of the back plate mechanism 2, when the support shaft 63 rotates to the left, the three groups of impedance elements 62 will be simultaneously compressed. Taking the left impedance mechanism 6 as an example, the rotation of the support shaft 63 to the left will further compress the impedance element 62 in the impedance mechanism 6. The tilt of the support shaft 63 of the middle impedance mechanism 6 will make the impedance element 62 be subjected to a diagonal compression force, which will also generate a component force hindering the leftward movement of the support shaft 63 after decomposition. The right impedance mechanism 6, the movement of the support shaft 63 will make the impedance element 62 be stretched, which will also generate a rightward resistance. The resistances in the three directions jointly form a comprehensive resistance hindering the left lateral flexion of the back plate mechanism 2.

[0027] In an embodiment, the support shaft 63 is provided with a protruding abutting ring, one end of the impedance element 62 abuts the bottom of the mounting portion, and the other end is connected with the abutting ring. The external force generated by the movement of the back plate mechanism 2 is transmitted to the impedance element 62 through the abutting ring on the support shaft 63, and the resistance generated by the impedance element 62 is reversely transmitted back to the support shaft 63 through the abutting ring, and then acts on the back plate mechanism 2. During the movement, when the external force exerted by the user and the resistance generated by the impedance element 62 reach a balance, the back plate mechanism 2 will be stabilized at the corresponding position to realize static exercise. When the external force exerted by the user is greater than the resistance, the back plate mechanism 2 will continue to move to complete the dynamic lateral flexion action. The force transmission and balance mechanism ensures that the impedance mechanism 6 can provide appropriate resistance for the lateral flexion of the waist according to the design requirements.

[0028] In an embodiment, the impedance member 62 is a spring, and as the backboard mechanism 2 inclines at an increasing angle during the left and right lateral flexion movement of the waist, the deformation of the spring increases, and the resistance also increases accordingly. This resistance change matches the force characteristics of the human waist muscles during the movement, and can provide stable and physiological resistance for the user. Meanwhile, by replacing springs with different stiffness coefficients, the resistance can be easily adjusted to meet the needs of different users and the same user at different rehabilitation stages.

[0029] In an embodiment, the seat plate provides a stable support plane for the user to ensure a stable contact point during the movement, and the pelvic fixation belt 5 is designed based on the principles of ergonomics and kinematics. The human pelvis is an important support part of the waist movement. If the position of the pelvis is unstable during the left and right lateral flexion rehabilitation movement of the waist, it will lead to inaccurate movement and dispersed force, and even cause movement injury due to body shaking. The pelvic fixation belt 5 surrounds and fixes the user's pelvis to stabilize and constrain it on the seat plate, limits the random movement of the pelvis, and enables the force of the waist movement to be concentrated on the target muscle group, ensuring the accuracy of the movement direction and the stability of the movement effect. The use method is as follows: the user first places the seat plate stably on the appropriate ground position, then sits on the side of the seat plate, adjusts the sitting posture so that the pelvis is in a comfortable and central position, then surrounds the pelvic fixation belt 5 around the pelvic position, adjusts the tightness of the fixation belt according to the user's condition, and the fixation belt should be stable and not cause excessive compression. After the fixation is completed, the user can start the related rehabilitation movement of the waist.

[0030] In an embodiment, the backboard mechanism 2 includes a backboard body and a torso fixation belt. The side of the backboard body facing the user is a contoured surface conforming to the physiological curvature of the human spine, which can better fit the shape of the human spine and provide natural and comfortable support for the spine during the user's waist rehabilitation movement, and disperse the body pressure. The torso fixation belt is arranged on the backboard body and is used to constrain the user's torso on the backboard body, so that the force of the waist movement can be effectively transmitted and accurately act on the target muscle group, improving the effect and accuracy of the rehabilitation movement. When in use, the user first stands in front of the backboard mechanism 2, aligns the back with the contoured surface of the backboard body, adjusts the body posture so that the spine fits well with the surface, then surrounds the torso fixation belt around the torso at an appropriate position, adjusts the tightness of the fixation belt according to the user's feeling, and the fixation belt should be stable and not affect breathing and normal activities. After the fixation is completed, the user can carry out the waist rehabilitation movement.

[0031] In an embodiment, the second rotating shaft 4 is provided with a buffer rubber pad at both ends, which has elastic deformation characteristics. When the back plate mechanism 2 performs left and right lateral bending movement to the limit position, the second rotating shaft 4 will move to the limit point, at which time the buffer rubber pad first contacts the surrounding fixed structure or limiting part. At the moment of contact, the rubber pad is extruded to cause elastic deformation, converting kinetic energy into elastic potential energy and storing it up. Then the elastic potential energy is slowly released, so that the impact force of the moving part is gradually attenuated to avoid hard collision. On the one hand, it can effectively reduce the damage to the waist caused by the movement impact. Because the huge impact force generated by the hard collision may be directly transmitted to the waist, causing muscle strain, joint damage and other problems. The buffer rubber pad can weaken the impact force to protect the waist.

[0032] In an embodiment, the first rotating shaft 3 and the second rotating shaft 4 are realized by rotating through bearings. In the scheme in which the first rotating shaft 3 and the second rotating shaft 4 are realized by rotating through bearings, the inner ring of the bearing is tightly sleeved on the rotating shaft and is fixedly connected with the rotating shaft to rotate together with the rotating shaft. The outer ring is installed on the corresponding support structure to remain relatively stationary. When the rotating shaft is acted on by an external force and tries to rotate, the inner ring rotates, and the rolling body rolls between the inner ring and the outer ring. Since the rolling friction is much smaller than the sliding friction, the rolling body rolls orderly under the specification guidance of the retainer, so that the inner ring can smoothly rotate relative to the outer ring, thereby realizing flexible rotation of the first rotating shaft 3 and the second rotating shaft 4, supporting the back plate mechanism 2 to complete left and right lateral bending and other movements.
