Description

Technical Field

[0001] The utility model relates to the field of balance training, in particular to a training device. Background Art

[0002] In the process of standing up and walking, the reconstruction of the body's sense of balance is a very important process. Balance disorder is one of the main functional obstacles to independent walking. Central nervous system diseases such as spinal cord injury, extracerebral vascular disease, and brain trauma will leave varying degrees of paraplegia or hemiplegia after onset. Joint dysfunction, joint stability destruction, muscle weakness, and imbalance of strength between muscle groups caused by lower limb bone and joint diseases will affect the patient's balance ability to varying degrees. Balance disorder is mainly manifested in the inability to stand alone or being able to stand alone but not walk alone. This may affect the rehabilitation process and daily living and work abilities, so rebuilding the body's sense of balance has become an urgent requirement for patients and an important issue facing rehabilitation medicine. At the same time, various balance trainings are also required for the elderly, athletes, etc., and balance training devices are generally required to assist people in balance training.

[0003] Balance training devices mainly force people into an unbalanced state through the movement of the device itself. People need to overcome this unbalanced state and achieve balance in order to achieve the purpose of training. Balance training devices in the prior art mainly force people into an unbalanced state by having people stand on a plane and then constantly changing the inclination angle and direction of the plane. However, imbalance is not only the imbalance caused by the shift of the center of gravity, but also includes the imbalance caused by sudden changes in momentum, such as the imbalance when moving at a certain speed and suddenly stopping. Conventional deflection balance training devices cannot achieve this. Existing balance training platforms generally have fewer degrees of freedom and cannot provide comprehensive training; or the training platform is too high from the ground, making users feel very unsafe and uncomfortable. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a training device so that a person can perform multi-degree-of-freedom training on a pedal of a relatively low height in a variety of imbalance states.

[0005] To achieve the above-mentioned and other related purposes, the present invention provides a training device, comprising:

[0006] Pedals, for people to stand on;

[0007] Racks, arranged on both sides of the pedal;

[0008] a base, the pedal being arranged on the base;

[0009] A moving unit, mounted on the frame and / or under the pedal, for driving the pedal and / or the base to move in at least two directions and to swing around at least two directions;

[0010] A connecting unit is used to connect the base and the moving unit, and the connecting unit has at least three rotational degrees of freedom.

[0011] In a specific embodiment of the present invention, it includes a first direction, a second direction and a third direction that are perpendicular to each other. The movable unit installed on the frame is used to drive the pedal to move along the second direction and the third direction respectively and to swing around the first direction, the second direction and the third direction respectively. The movable unit installed under the pedal drives the pedal to move along the first direction.

[0012] In a specific embodiment of the present invention, the moving unit includes a first moving mechanism, which is installed on the base and is used to drive the pedal to move along the first direction.

[0013] In a specific embodiment of the present invention, there are two racks, and the moving unit includes two third moving mechanisms respectively arranged on the two racks. The third moving mechanism is arranged on the rack, and the third moving mechanism is used to drive the base to move forward and backward in the third direction.

[0014] In a specific embodiment of the present invention, the moving unit includes a second moving mechanism, which is arranged on the third moving mechanism, and the second moving mechanism is used to drive the base to move up and down in the second direction.

[0015] In a specific embodiment of the present invention, two second moving mechanisms are provided on one of the racks, and one is provided on the other rack.

[0016] In a specific embodiment of the present invention, the connecting unit connects the second moving mechanism and the base.

[0017] In a specific embodiment of the present invention, the connection unit is a ball joint or a universal joint.

[0018] In a specific embodiment of the present invention, a displacement compensation mechanism is provided between the base and the second moving mechanism, the displacement compensation mechanism is used to compensate for the displacement difference generated when the pedal swings, and the connecting unit is connected to the displacement compensation mechanism.

[0019] In a specific embodiment of the present invention, the displacement compensation mechanism includes a first slide rail provided on the base and a third slide rail provided on the second moving mechanism, the first slide rail is arranged along a first direction, and the third slide rail is arranged along a third direction.

[0020] The present invention proposes a training device that can provide two unbalanced states: center of gravity deflection and center of gravity shift, enabling better training. The base's movement allows the user to move and swing accordingly, enabling balance training in both movement and swinging states. This allows for training not only in maintaining balance while walking on various slopes, but also in the event of a sudden stop or encountering an obstacle. This diverse training state is beneficial for patient rehabilitation or improving balance in athletes. The combination of three mutually perpendicular moving units, or three mutually perpendicular moving units and a rotation unit, enables six degrees of freedom (DOF) training, even allowing for independent movement of the two pedals. The racks are positioned on either side of the pedals, allowing the pedals to be positioned lower, ensuring multi-DOF training at a safe, natural, and appropriate height. The simplified structural design requires fewer motors or drive units, and the connection unit and displacement compensation mechanism are simpler. This also expands its application scenarios and scope. For example, placing a treadmill or running platform on top allows users to change their posture and position while running, helping to better train their balance, particularly active balance during exercise.

[0029] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features within these embodiments may be combined with one another, unless they conflict.

[0030] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be changed at will, and the component layout may also be more complex.

[0031] For simplicity, all examples in this article are based on a static standing position. There are three main imbalance states in humans:

[0032] 1. Self-rotational imbalance, such as when spinning in circles, corresponds to the self-rotational movement. At this time, the rotational acceleration of the body mass can be used to achieve angle correction. In this case, the rotational swing acceleration is mainly used to generate a rotational acceleration in the opposite direction of the body.

[0033] 2. Tilt imbalances, such as those caused by standing on an inclined surface, correspond to forward and backward and side-to-side swinging movements. This can be achieved by "catching balance" by stepping forward, backward, or sideways to move the platform back to the user's displaced center of gravity. This can be done naturally by simply moving the hips to keep the center of gravity as high as possible above the center of force.

[0034] 3. Inertial imbalance, such as the imbalance caused by standing on a bus and suddenly braking, corresponds to movement. At low disturbance levels, simply shifting the center of force in the foot contact area can keep the center of force as close to the center of gravity as possible. This can be accomplished by applying more force to the toes or heel, or to one side of the foot or the other.

[0035] Various combinations of these modes can be used simultaneously. Gravity correction is the most natural way to correct balance and requires very little energy.

[0036] like Figure 1-6 As shown, the present invention provides a training device, which includes a pedal 10 , a frame 20 , a base 30 , a moving unit and a connecting unit 40 .

[0037] The pedal 10 is used for a person to stand on. When a person stands on the pedal 10, the movement of the pedal 10 is converted into the movement of the human foot, thereby simulating the movement of a person in various environments. A plantar force measurement plate can be provided on the pedal 10 to measure plantar force data when a person stands on the pedal 10.

[0038] The frame 20 is provided on both sides of the pedal 10 to provide a support structure for the entire device.

[0039] The base 30 is used to support the pedal 10 so that the pedal 10 can move and swing on the base 30 .

[0040] The moving unit is mounted on the frame 20 and / or under the pedal 10 and is used to drive the pedal 10 and / or the base 30 to move in at least two directions and to swing in at least two directions. This allows the person on the pedal 10 to rotate or swing, placing them in two unbalanced states: a deflected center of gravity and a shifted center of gravity.

[0041] The connecting unit 40 is used to connect the base 30 and the mobile unit, and the connecting unit 40 has at least three rotational degrees of freedom. In this way, the rotation or swinging of the person on the pedal 10 can be achieved only by the staggered movement of the mobile unit in the same direction. In this way, the pedal 10 in the present application has both moving and swinging movements, which can put the person in two unbalanced states of center of gravity deflection and center of gravity movement. The two unbalanced states can also be carried out at the same time, which can better train the person. It can not only train the person's ability to maintain balance when walking on various slopes, but also train the person's balance ability when suddenly stopping or suddenly encountering obstacles. More diverse training states are more conducive to patient rehabilitation or the improvement of athletes' balance ability.

[0042] In a specific embodiment of the present invention, it includes a first direction, a second direction, and a third direction that are perpendicular to each other. The mobile unit installed on the frame 20 is used to drive the pedal 10 to move in the second direction and the third direction respectively, and to swing around the first direction, the second direction, and the third direction respectively. The mobile unit installed under the pedal 10 drives the pedal 10 to move in the first direction. In this way, the human body can move in six degrees of freedom, corresponding to forward and backward swinging, self-rotation, left and right swinging, left and right movement, up and down movement, and forward and backward movement. Multiple movements can also be performed simultaneously, further enhancing the diversity of training states. Among them, the first direction corresponds to the left and right direction of the human body, that is, the X direction in the figure, the second direction corresponds to the up and down direction of the human body, that is, the Z direction in the figure, and the third direction corresponds to the front and back direction of the human body, that is, the Y direction in the figure.

[0043] In a specific embodiment of the present invention, the mobile unit includes a first mobile mechanism 50, which is mounted on the base 30 and is used to drive the pedal 10 to move in a first direction. Two pedals 10 can be provided, and the first mobile mechanism 50 can drive the two pedals 10 closer or farther away. This design enables the system to be adjusted according to the body shape or needs of different users. Users can adjust the distance between the pedals 10 according to the size and position of their feet, thereby providing a more comfortable user experience. The overall translation function of the pedal 10 in the first direction can simulate the left and right swing or imbalance state of the human body when walking or running. This is very useful for users who are undergoing rehabilitation training, strengthening physical fitness or performing other sports-related activities. In this way, users can experience the feeling of dynamic movement in a static environment, increasing the diversity and effect of training.

[0044] In a specific embodiment of the present invention, there are two racks 20, and the mobile unit includes two third mobile mechanisms 70 respectively arranged on the two racks 20, and the third mobile mechanism 70 is arranged on the rack 20, and the third mobile mechanism 70 is used to drive the base 30 to move forward and backward in the third direction. When the two third mobile mechanisms 70 move forward and backward in an offset manner, the base 30 can be rotated around the second direction. Through the rotation of the base 30, the system can simulate the human body's spinning movement. This is particularly useful for users who need to perform rotation training or rehabilitation. For example, in dance training or sports rehabilitation, it can help users master and practice the balance and coordination of rotation. The ability to realize the rotation of the base 30 around the second direction allows the device to provide a variety of movement modes and training methods. This diversity can increase the fun and effectiveness of training and help to exercise the user's body in all directions.

[0045] In a specific embodiment of the present invention, the mobile unit includes a second mobile mechanism 60, which is arranged on a third mobile mechanism 70, and the second mobile mechanism 60 is used to drive the base 30 to move up and down in the second direction. The displacement difference of the second mobile mechanisms 60 on both sides can realize the swing of the pedal 10 around the third direction, and can also simulate the posture of a human body standing on a slope inclined to the left and right. The synchronous movement of the second mobile mechanisms 60 on both sides can realize the up and down lifting of the human body to simulate the weightless environment when the human body rides on the lifting mechanism. The combination of up and down movement and swinging functions can provide users with a more realistic sports experience, such as simulating the feeling of walking or lifting on a slope. This realistic simulation helps to improve the effectiveness and fun of training. This design enables the device to provide not only translation and rotational movement, but also up and down movement and tilt simulation, which enhances the training function and adaptability of the device and can meet various sports and rehabilitation needs.

[0046] In a specific embodiment of the present invention, two second mobile mechanisms 60 are provided on one of the frames 20, and one is provided on the other frame 20. In this way, the pedal 10 can be swung about the first direction by the displacement difference between the two second mobile mechanisms 60 on the same side, and the posture of a human body standing on a slope that tilts forward and backward can also be simulated. This configuration can simulate different terrain inclinations, increase the diversity of training, and enable users to train at different inclination angles, thereby improving exercise effects and adaptability. By adjusting the number and configuration of the second mobile mechanisms 60 on different frames 20, the device can flexibly adapt to various exercise and training needs, including training that tilts forward and backward or walks on a slope.

[0047] In one embodiment of the present invention, the connecting unit 40 connects the second moving mechanism 60 and the base 30. This enables the pedal 10 to move and swing in various directions, thereby simulating a variety of imbalanced states. This design allows the pedal 10 to perform complex movements and adjustments during training, facilitating more comprehensive balance training and adapting to diverse exercise scenarios.

[0048] In one embodiment of the present invention, the connection unit 40 is a ball joint or universal joint. These joints allow the connection to rotate freely in multiple directions, enabling complex movements of the pedal 10, such as rotation and swinging. This provides high flexibility, allowing the pedal 10 to adapt to different exercise patterns and tilt angles, enhancing training diversity. They also reduce stress that may arise from misaligned connection components, ensuring stable system operation and improving the user's exercise experience.

[0049] In a specific embodiment of the present invention, a displacement compensation mechanism 80 is provided between the base 30 and the second moving mechanism 60. The main function of the displacement compensation mechanism 80 is to compensate for the displacement difference generated by the pedal 10 during the swinging process. When the pedal 10 swings, displacement deviations may occur due to the structure or movement mode. The compensation mechanism compensates for these differences by adjusting the position or movement mode to ensure the stability and accuracy of the pedal 10 in all directions. The displacement compensation mechanism 80 helps to maintain the relative position between the pedal 10 and the base 30 stable, thereby improving the overall stability of the equipment and preventing system imbalance or displacement abnormalities caused by swinging. By connecting the connecting unit 40 to the displacement compensation mechanism 80, it can be ensured that the connecting unit 40 can maintain the required degrees of freedom of movement when handling the multi-degree-of-freedom movement of the pedal 10, and reduce the additional load or stress caused by the swinging of the pedal 10.

[0050] In a specific embodiment of the present invention, the displacement compensation mechanism 80 includes a first slide rail 81 provided on the base 30 and a third slide rail 82 provided on the second moving mechanism 60, the first slide rail 81 is arranged along a first direction, and the third slide rail 82 is arranged along a third direction. The arrangement of the slide rails and the coordination with the ball joint or universal joint can effectively compensate for the maintenance difference generated by the pedal 10 during rotation or swinging. Maintenance difference refers to the structural misalignment caused by the relative displacement or angle difference between the moving parts. Through the smooth sliding of the slide rails, the system can maintain the expected motion trajectory and position, reducing the problems caused by maintenance difference. The design of the slide rails can reduce or eliminate the jamming phenomenon caused by the mutual interference of the various components of the equipment during rotation or swinging. The slide rails provide a smooth motion path, allowing the connecting parts to move freely within their range of motion, avoiding obstructions caused by mechanical interference.

[0051] The moving mechanism in the above scheme can be a screw-nut mechanism, a hydraulic rod, a pneumatic rod, a linear motor, etc., and in this application, a screw-nut mechanism is preferred.

[0052] In summary, the present invention provides a training device that can provide two unbalanced states: center of gravity deflection and center of gravity movement, which can better train personnel. The base 30 can be moved and swung by the movement of the base 30, thus completing balance training in both moving and swaying states. This not only trains the personnel's ability to maintain balance when walking on various inclined surfaces, but also trains the personnel's ability to balance when suddenly stopping or encountering obstacles. The more diverse the training states, the more conducive it is to patient rehabilitation or to improving the balance ability of athletes.
