Description

Technical Field

[0001] This invention belongs to the field of balance training device technology, specifically, it relates to a balance training device. Background Technology

[0002] In the fields of rehabilitation medicine, physical training, and elderly health management, balance training is a key means to improve body coordination, prevent fall risk, and promote neuromuscular function recovery. It is widely applicable to patients with sequelae of stroke, people recovering from orthopedic surgery, the elderly, and sports enthusiasts. As people pay more attention to health management, higher demands are being placed on the functionality, safety, and convenience of balance training equipment.

[0003] Most protective railings are fixed installation structures that cannot flexibly adapt to the swinging of the placement board. This may limit the range of motion during training, affecting the training effect, and it is also difficult to provide timely and gentle reverse support when the patient loses balance, resulting in poor protective effect.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a balance trainer.

[0006] The basic concept of the technical solution adopted in this invention is: A balance trainer includes a mounting base and two handrails disposed above the mounting base. External movable guardrails are also provided on both sides of the mounting base. Multiple rubber pads are provided on the opposite sidewalls of the two external movable guardrails. A support plate is disposed above the mounting base, and a display screen is disposed on the support plate. The mounting base has a circular slot, and a rectangular slot is further formed within the circular slot. A circular placement plate is disposed on the circular slot, and a mounting cylinder is disposed at the bottom of the circular placement plate. A driving assembly is disposed within the inner cavity of the mounting cylinder, and a connecting block is disposed on the driving assembly. The upper end of the connecting block is disposed at the bottom of the circular placement plate. A cylinder is disposed at the bottom of the mounting cylinder, and the cylinder is disposed at the bottom of the inner cavity of the circular slot.

[0007] In a preferred embodiment of the present invention, two concave mounting plates are provided above the inner cavity of the mounting cylinder.

[0008] In a preferred embodiment of the present invention, the drive assembly includes a servo motor disposed on the inner wall of the mounting cylinder, a rotating rod disposed at the output end of the servo motor, a mounting bearing disposed at the end of the rotating rod away from the servo motor, the mounting bearing being disposed on the inner wall of the concave mounting plate, and a connecting block disposed on the rotating rod.

[0009] In a preferred embodiment of the present invention, a C-shaped connecting rod is provided above each of the two plug-in plates. The two C-shaped connecting rods are symmetrical to each other. A swing arm is provided at the opposite end of each of the two C-shaped connecting rods. A rotating rod is provided on one side wall of each of the two swing arms, and the rotating rod is rotatably disposed on the inner wall of the circular slot.

[0010] In a preferred embodiment of the present invention, each of the two rectangular slots has a slide rail on one side wall facing the other, and a sliding block is slidably disposed between each pair of slide rails, with the two sliding blocks fitting together in the rectangular slot.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0018] like Figures 1 to 9As shown, a balance training device includes a mounting base 1 and two handrails 2 disposed above the mounting base 1. External movable guardrails 11 are also provided on both sides of the mounting base 1. Multiple rubber pads 12 are provided on the opposite side walls of the two external movable guardrails 11. A support plate 3 is provided above the mounting base 1, and a display screen 4 is provided on the support plate 3. A circular slot 5 is opened on the mounting base 1, and a rectangular slot 6 is also opened inside the circular slot 5. A circular placement plate 7 is provided on the circular slot 5, and a mounting cylinder 18 is provided at the bottom of the circular placement plate 7. A driving component is provided inside the mounting cylinder 18, and a connecting block 21 is provided on the driving component. The upper end of the connecting block 21 is located at the bottom of the circular placement plate 7. A cylinder 17 is provided at the bottom of the mounting cylinder 18, and the cylinder 17 is located at the bottom of the inner cavity of the circular slot 5. The circular placement plate 7 can swing left and right by 30 degrees under the drive component, effectively achieving the balance training requirements. At the same time, when the circular placement plate 7 swings more than 10 degrees, the external movable guardrail 11 contacts the patient through the rubber pad 12 on its side wall and provides a reverse push force, which not only assists the balance training but also ensures the patient's safety. The other external movable guardrail 11 is attached to the connecting block 21 by means of the return spring 23 and can be flexibly adjusted with the swing. When the patient is tired from training, the control cylinder 17 can push the circular placement plate 7 upward to allow the patient to sit down and rest conveniently.

[0019] In a specific embodiment, two concave mounting plates 19 are provided above the inner cavity of the mounting cylinder 18. The two concave mounting plates 19 are symmetrical to each other and fit into the inner wall of the mounting cylinder 18. Insertion plates 22 are slidably provided in the inner cavities of the two concave mounting plates 19. The two insertion plates 22 are symmetrical to each other, and the opposite side walls of the two insertion plates 22 are respectively attached to the connecting block 21. Two return springs 23 are respectively provided at opposite ends of the two insertion plates 22. The ends of the two return springs 23 away from the insertion plates 22 are respectively provided on the inner wall of the concave mounting plates 19. In this configuration, the concave mounting plate 19 provides a stable sliding mounting base for the plug-in plate 22. Its fit with the inner wall of the mounting cylinder 18 restricts the radial sway of the plug-in plate 22, ensuring that the plug-in plate 22 slides horizontally only along the inner cavity of the concave mounting plate 19. The reset spring 23 ensures that the plug-in plate 22 always fits against the connecting block 21, which not only ensures that the connecting block 21 can accurately squeeze the plug-in plate 22 to achieve transmission when it swings, but also drives the plug-in plate 22 to return to its original position synchronously when the connecting block 21 resets, ensuring the continuity and reliability of the transmission.

[0020] Furthermore, the drive assembly includes a servo motor 24, which is disposed on the inner wall of the mounting cylinder 18. A rotating rod 25 is disposed at the output end of the servo motor 24, and a mounting bearing 26 is disposed at the end of the rotating rod 25 away from the servo motor 24. The mounting bearing 26 is disposed on the inner wall of the concave mounting plate 19, and a connecting block 21 is disposed on the rotating rod 25. In this configuration, the servo motor 24 serves as the drive source, providing power for the rotating rod 25 to reciprocate 30 degrees left and right. The mounting bearing 26 is nested in the inner wall of the concave mounting plate 19, which can support the rotating rod 25 and reduce frictional loss during its rotation, ensuring the smoothness of the rotation of the rotating rod 25. The rotating rod 25 is fixedly connected to the connecting block 21, which can directly transmit the rotational power of the servo motor 24 to the connecting block 21, thereby driving the circular placement plate 7 to swing synchronously, providing core power for balance training.

[0021] Furthermore, each of the two plug-in plates 22 is provided with a C-shaped connecting rod 20, which are symmetrical to each other. A swing arm 16 is provided at each opposite end of the two C-shaped connecting rods 20. A rotating rod 27 is provided on one side wall of each swing arm 16, and the rotating rod 27 is rotatably mounted on the inner wall of the circular slot 5. In this configuration, the C-shaped connecting rod 20 serves as a transmission connector between the plug-in plate 22 and the swing arm 16, accurately transmitting the horizontal movement of the plug-in plate 22 to the swing arm 16, allowing the swing arm 16 to rotate with the assistance of the rotating rod 27.

[0022] Furthermore, each of the two rectangular slots 6 has a slide rail 10 on one of its opposite sidewalls. A sliding block 9 is slidably mounted between each pair of slide rails 10, with the two sliding blocks 9 fitting into the rectangular slot 6. In this configuration, the slide rail 10 provides horizontal sliding guidance for the sliding blocks 9, restricting their movement to only along the length of the rectangular slot 6, preventing them from shifting or wobbling. The fitting of the sliding blocks 9 with the rectangular slot 6 reduces sliding gaps, improves sliding stability, and provides a reliable support foundation for the horizontal movement of the moving plate 8.

[0023] Furthermore, two sliding blocks 9 are each provided with a movable plate 8 on their opposite sidewalls. The two movable plates 8 are symmetrical to each other and are movably inserted through the mounting base 1. The opposite ends of the two movable plates 8 are respectively connected to the C-shaped connecting rod 20, and each of the opposite ends of the two movable plates 8 is provided with a drive plate 13. In this configuration, the movable plate 8 is movably inserted through the mounting base 1, allowing it to move freely horizontally within the mounting base 1 without interference. The movable plate 8 is connected to the sliding block 9 and the C-shaped connecting rod 20, respectively, and can transmit the horizontal movement of the C-shaped connecting rod 20 to the sliding block 9, causing the sliding block 9 to slide along the slide rail 10.

[0024] Furthermore, each of the two drive plates 13 has a sliding groove 14 on one of its opposite sidewalls. The two sliding grooves 14 are symmetrical to each other, and a sliding slider 15 is slidably mounted inside each of the two sliding grooves 14. Each sliding slider 15 is equipped with a swing arm 16. In this configuration, the sliding groove 14 provides precise sliding guidance for the sliding slider 15, restricting the sliding slider 15 to slide only along the length direction of the drive plate 13.

[0025] The implementation principle of the balance trainer of the present invention is as follows: First, when the patient is performing balance training: the patient stands on the circular placement plate 7. At this time, the drive component is controlled to operate, so the servo motor 24 in the drive component can run. When the drive component is running, it can drive the rotating rod 25 to rotate back and forth by 30 degrees left and right (the specific way to control the operation of the drive component and achieve the left and right 30-degree swing is existing technology and programming technology). When the rotating rod 25 rotates, it can drive the connecting block 21 to rotate, and thus the connecting block 21 can drive the circular placement plate 7 to rotate, so that the circular placement plate 7 can swing left and right by 30 degrees, thus achieving the effect of balance training. Simultaneously, when connecting block 21 swings approximately 30 degrees to the left or right: taking the swing of connecting block 21 to the right as an example: When the connecting block 21 swings to the right, it can initially squeeze the plug plate 22 to move horizontally back and forth in the inner cavity of the concave mounting plate 19. When the plug plate 22 moves, it can drive the C-shaped connecting rod 20 to move. When the C-shaped connecting rod 20 moves, it can drive the swing arm 16 to rotate with the assistance of the rotating rod 27. When the swing arm 16 rotates, it can pull the moving slider 15 to move horizontally with the assistance of the drive plate 13, the sliding block 9, and the slide rail 10. Therefore, the sliding block 9 can drive the external moving guardrail 11 to approach the mounting base 1 through the moving plate 8. Therefore, before rotating 10 degrees, the rubber pad 12 set on the external moving guardrail 11 does not contact the patient. When it exceeds 10 degrees, the rubber pad 12 can contact the patient, thus giving the patient a thrust opposite to the rotation force, thereby ensuring that the patient can be assisted in balance training during physical balance training. At this time, the plug plate 22 on the other side is flipped by the connecting block 21, so that the plug plate 22 can always be attached to the connecting block 21 with the assistance of the reset spring 23 set in the inner cavity of the concave mounting plate 19. When the plug plate 22 moves, it can drive the C-shaped connecting rod 20 to move. When the C-shaped connecting rod 20 moves, it can drive the swing arm 16 to rotate with the assistance of the rotating rod 27. When the swing arm 16 rotates, it can drive the moving slider 15 to move horizontally with the assistance of the drive plate 13, the sliding block 9 and the slide rail 10. Therefore, the sliding block 9 can drive the external moving guardrail 11 away from the mounting base 1 through the moving plate 8. When the patient is tired from exercising, return the patient to the initial position (i.e., the position of the circular placement plate 7 in the attached diagram of the instruction manual). At this time, the staff controls the cylinder 17 to operate, so that the cylinder 17 can push the circular placement plate 7 upward, allowing the patient to sit on the circular placement plate 7 to rest.
