Description

Technical Field

[0001] This invention relates to the field of sports equipment technology, and more specifically, to an adjustable rocking board. Background Technology

[0002] The rocking board is a multi-functional balance training and dynamic support device suitable for various postures such as sitting, standing, kneeling, and lying down. Its adjustable swing design in both directions meets the needs of balance training, core muscle training, and leisure use. The board surface is made of 18mm birch wood with a non-slip treatment, combining safety and durability. It is available in apple green, sky blue, and dark pink, combining aesthetics and practicality. Its core structure integrates an adjustable mechanical fulcrum with ergonomic design, making it suitable for dynamic posture adjustment in home fitness, rehabilitation training, or office settings.

[0003] Currently, most rocking boards on the market use fixed fulcrums or simple hinge connections, which are inconvenient for dynamic balance adjustment. This makes it easy for users to tip over or wobble in scenarios with a high center of gravity, such as standing or kneeling, due to excessive swing amplitude or insufficient friction at the fulcrum, posing a safety hazard. In addition, the swing amplitude and tilt angle of most existing products are fixed, and cannot be flexibly adjusted according to the user's physical condition, training intensity, or usage posture (such as low-amplitude swing required when lying down, and high-intensity balance training when standing). This limits the applicability to users with different physical abilities and makes it difficult to meet the personalized pressure support needs in rehabilitation training.

[0004] Therefore, we propose an adjustable rocking board. Summary of the Invention

[0005] This invention provides an adjustable rocking board, which features a central plate at the bottom of the board surface. Two adjusting devices are installed within the central plate, each including a sliding assembly, a damper, and a rotating assembly. The sliding assembly slides along a groove at the bottom of the board surface, while the rotating assembly causes the damper to tilt in the opposite direction. Combined with the rocking assembly between the semi-circular plate on the base plate and the board surface, the damper allows adjustment of the training pressure during rocking, achieving dynamic control of the rocking resistance and amplitude. This solves the problems mentioned in the background section, namely:

[0006] Existing rocker boards suffer from inconvenient dynamic balance adjustment, fixed swing amplitude and tilt angle, resulting in insufficient stability and difficulty in meeting personalized needs.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An adjustable rocking board includes a board surface, a central plate located near the center of the bottom of the board surface, a groove inside the central plate, and two adjustment devices inside the central plate for adjusting the training pressure during board rocking.

[0009] The adjustment device includes sliding components. Two sliding components are slidably connected to the inside of the groove at the bottom of the plate near both ends. A damper is fixedly connected to the end of the sliding component. The damper is located inside the groove of the center plate. A rotating component is fixedly connected to the other end of the damper. Two rotating components are movably connected to the inside of the center plate near the bottom. The rotation of the rotating components will cause the two dampers to tilt in opposite directions.

[0010] In the above technical solution, a base plate is fixedly connected to the bottom of the center plate, and semicircular plates are fixedly connected to the top of the base plate near both sides. A plate surface is movably connected between the tops of the two semicircular plates, and a swinging component is directly provided inside the plate surface and the semicircular plates.

[0011] Preferably, the swing assembly includes a rotating ball, which is movably connected inside the semi-circular plate, and a support rod is fixedly connected to the outer wall of the rotating ball, which is fixedly connected to the bottom of the plate.

[0012] The top of the plate has multiple protrusions, which are hemispherical and made of silicone.

[0013] Based on this, the sliding assembly includes a ball bearing that is slidably engaged in a groove at the bottom of the plate. A sliding rod is symmetrically fixedly connected to the outer wall of the ball bearing, and the sliding rod is slidably connected to the groove at the bottom of the plate. A moving rod is fixedly connected to the outer wall of the ball bearing near the bottom, and a damper is fixedly connected to the bottom of the moving rod.

[0014] Preferably, the rotating assembly includes a sphere that is movably engaged inside a groove in a central plate. A damper is fixedly connected to the top of the sphere. A groove is provided inside the sphere, and a large gear is provided inside the groove. A rotating rod is coaxially connected between the large gear and the sphere.

[0015] A small gear is meshed with the outer wall of the large gear. A shaft is provided between the small gear and the inside of the center plate. The small gears in the two adjustment devices are meshed with each other. A motor is provided at the end of one of the shafts that extends out of the center plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In an adjustable rocking board, through the mechanical linkage of two adjustment devices (sliding component, damper, and rotating component) in the center plate at the bottom of the board, the rotating component drives the two dampers to tilt in opposite directions, so that when the sliding component slides along the board's groove, it drives the dampers to move synchronously, changing the lever arm length and resistance coefficient of the damper and the rocking fulcrum, thereby achieving dynamic and precise adjustment of the board's rocking resistance and amplitude. In scenarios with a high center of gravity, such as standing or kneeling, the resistance can be increased by increasing the damping lever arm, effectively suppressing tipping and swaying, and significantly improving the dynamic balance adjustment capability and safety of use.

[0018] 2. In an adjustable rocking board, a circular swing trajectory is formed by the swing components (ball bearings, support rods) between the semicircular plates on both sides of the base plate and the board surface. Combined with the adjustable damping parameters of the adjustment device, the user can simultaneously adjust the tilt angle of the dampers on both sides by driving the gear meshing structure of the rotating component (the small gear drives the large gear to rotate) through the motor, so as to achieve stepless switching of swing amplitude and tilt angle (such as small angle and low resistance in lying position, and large angle and high resistance in standing position); to meet the training intensity needs of users with different physical fitness and to adapt to the scenario of personalized pressure support in rehabilitation training.

[0029] 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. Example

[0030] Currently, existing rocker boards suffer from inconvenient dynamic balance adjustment, fixed swing amplitude and tilt angle, resulting in insufficient stability and difficulty in meeting personalized needs. This invention provides an adjustable rocker board, such as... Figures 1-4 As shown, it includes a board surface, a center plate located near the center of the bottom of the board surface, a groove inside the center plate, and two adjustment devices inside the center plate. The adjustment devices are used to adjust the training pressure when the board surface is swaying.

[0031] The adjustment device includes sliding components. Two sliding components are slidably connected to the inside of the groove at the bottom of the plate near both ends. A damper is fixedly connected to the end of the sliding component. The damper is located inside the groove of the center plate. A rotating component is fixedly connected to the other end of the damper. Two rotating components are movably connected to the inside of the center plate near the bottom. The rotation of the rotating components will cause the two dampers to tilt in opposite directions.

[0032] When implementing, refer to Figure 2 and Figure 7 As shown, a base plate is fixedly connected to the bottom of the center plate, and semicircular plates are fixedly connected to the top of the base plate near both sides. A plate surface is movably connected between the tops of the two semicircular plates, and a swinging component is directly provided between the plate surface and the interior of the semicircular plates.

[0033] The swing assembly includes a ball bearing that is movably connected inside a semi-circular plate. A support rod is fixedly connected to the outer wall of the ball bearing, and the support rod is fixedly connected to the bottom of the plate.

[0034] Specifically, the swing is supported by semicircular plates fixed on both sides of the top of the base plate, and the hollow area inside the plates accommodates the rotating beads. The rotating beads are movably connected to the inner wall of the semicircular plates through bearings or smooth curved surfaces, and can rotate freely around their own center. The support rods fixed to the outer wall of the rotating beads extend upward and are rigidly connected to the bottom of the plate.

[0035] The center of the rotating bead coincides with the center of the semicircular plate, forming the geometric center of the board's swing. This ensures that all swing trajectories are symmetrically distributed around this center when the board swings back and forth. When the user applies an external force (such as a shift in body weight) to tilt the board, the board rotates the rotating bead inside the semicircular plate via the support rod. Since the rotating bead can rotate in the forward and backward directions according to the design, the board swings back and forth along the arc surface of the semicircular plate with the center of the rotating bead as the fulcrum. The support rod, as a rigid connector, synchronously transmits the swing displacement of the board to the rotating bead, making the rotation angle of the rotating bead completely consistent with the tilt angle of the board. For example, when the board tilts forward by 10°, the support rod pushes the rotating bead to rotate forward by 10°, and vice versa.

[0036] Among them, see Figure 2 As shown, the top of the board has multiple hemispherical bumps made of silicone. Due to the properties of silicone, its surface friction coefficient is significantly higher than that of traditional birch wood, and it also possesses high elasticity and weather resistance.

[0037] When a user's feet, knees, or other parts of the body come into contact with the bumps, the elastic deformation of the silicone can closely conform to the contact surface, such as the tread pattern of a shoe sole or the surface of a knee brace, filling microscopic gaps, forming a physical interlocking effect, increasing static friction, and preventing slippage. The curved design of the hemispherical bumps transforms the contact area between a single bump and the contact surface from a planar "point contact" to a "curved surface contact," increasing the effective contact area. At the same time, the overall pressure is distributed to the plate surface through multi-point distribution, improving the uniformity of load bearing.

[0038] When a user moves their center of gravity or swings on the board, the curved edge of the hemispherical protrusion can produce an edge engagement effect: for example, when the edge of the sole contacts the tangential direction of the protrusion hemisphere, the elastic deformation of the protrusion will provide a certain resistance torque to suppress sudden sliding tendencies.

[0039] Additionally, see Figure 6 As shown, the sliding assembly includes a ball bearing that is slidably engaged in a groove at the bottom of the plate. A sliding rod is symmetrically fixedly connected to the outer wall of the ball bearing, and the sliding rod is slidably connected in a groove at the bottom of the plate. A movable rod is fixedly connected to the outer wall of the ball bearing near the bottom, and a damper is fixedly connected to the bottom of the movable rod.

[0040] When the rotating component drives the damper to tilt (such as when the motor drives the ball to rotate through the gear set), the upper end of the damper pulls the ball to roll in the groove through the moving rod; since the sliding rod is embedded in the guide groove of the groove, its linear sliding trajectory restricts the ball to move only along the length direction of the plate (front and back direction), avoiding lateral deviation and ensuring that the adjustment path of the damper is precise and controllable.

[0041] The horizontal distance (i.e., lever arm) between the damper and the oscillating fulcrum (center of the ball) is directly changed by the displacement of the sliding component. When the ball slides towards the front end of the plate, the front end of the damper rises and the rear end presses down, which, in conjunction with the tilting action of the rotating component, increases the angle between the damper and the fulcrum. According to the lever principle, the resistance torque increases significantly, achieving a high-intensity training mode; conversely, when the ball slides backward, the resistance torque decreases, adapting to low-intensity requirements.

[0042] See Figure 5 As shown, the rotating assembly includes a sphere that is movably engaged inside a groove in the center plate. A damper is fixedly connected to the top of the sphere. A groove is provided inside the sphere, and a large gear is provided inside the groove. A rotating rod is coaxially connected between the large gear and the sphere. A small gear is meshed with the outer wall of the large gear. A shaft is provided between the small gear and the inside of the center plate. The small gears in the two adjusting devices are meshed with each other. A motor is provided at the end of one of the shafts that protrudes from the center plate.

[0043] When the user starts the motor via the control switch, the motor output shaft drives the shaft to rotate, which in turn drives the pinion to rotate clockwise or counterclockwise. Since the pinions on both sides mesh with each other, when one pinion rotates clockwise, the other side rotates counterclockwise in sync, forming a reverse motion. The pinion drives the large gear to rotate through the meshing of its teeth. Since the large gear is coaxial with the ball, the ball rotates synchronously with the large gear, which in turn causes the damper connected to the top to tilt in the opposite direction (e.g., when the left damper tilts forward, the right damper tilts backward).

[0044] Since the rotation angle of the sphere directly determines the angle between the damper and the bottom of the plate. When the sphere rotates forward At an angle, the front end of the damper is pressed down and the rear end is raised, increasing the horizontal lever arm relative to the fulcrum (center of the ball). According to the lever principle, the damper's resistance torque increases with... The force increases linearly, enabling high-intensity training; conversely, when the sphere rotates backward, the lever arm decreases and the resistance torque decreases, adapting to low-intensity balance training or rehabilitation scenarios.
