Magic roll ball training device

Abstract

This utility model discloses a magic ball training device, relating to the technical field of ball training equipment. It includes a base frame with a fixing mechanism at the outer triangular portion. Three sets of fixing mechanisms have connecting frames fixed at their tops at an angle. A ball is movably connected to the inner side of the connecting frame, and multiple sets of ball bearings are movably connected to the inner side of the connecting frame, contacting the ball. This utility model significantly improves the stability and service life of the equipment through innovative dynamic locking and intelligent control design. It effectively solves the problem of wear caused by accidental rotation of traditional balls. Regarding accidental contact prevention and wear control, when idle, the outer rotor motor drives the clamping arm to extend the clamping rollers. The three sets of clamping rollers adhere to the surface of the ball through the elastic force of torsion springs, using friction to lock the ball and prevent unexpected rotation due to vibration or collision. This reduces the friction frequency between the ball and the connecting frame, extending the service life of the ball and the fixing frame, and ensuring the accuracy of sensor detection.

Description

Technical Field

[0001] This utility model relates to the technical field of ball rolling training equipment, specifically a magic ball rolling training device. Background Technology

[0002] In interactive ball-rolling experiences or magic ball-pushing games, children push or tilt the ball to control characters or objects in the game. The ball's movements are fed back to the screen in real time via sensors. In this case, various types of sensors may be used. For example, an accelerometer can detect the ball's acceleration, tilt angle, and other information to determine whether the ball is being pushed or tilted, as well as the direction and force of the movement. A position sensor may also be used to detect changes in the ball's position in a specific space to determine its trajectory and state, which is then translated into corresponding actions for characters or objects in the game.

[0003] In the existing technology field, the ball is usually placed on a fixed frame for rolling. However, this design has obvious defects. During daily use, even if the ball is not rolled, when the device is subjected to external vibration, collision or handling, the ball is very likely to rotate unexpectedly due to accidental impact. This unnecessary rotation will frequently increase the friction between the ball and the fixed frame, which not only reduces the service life of the ball and the fixed frame, but also leads to a decrease in detection accuracy and a deterioration in equipment stability, seriously affecting the performance and reliability of the related equipment. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide a magic ball training device to solve the technical problems in the background art mentioned above.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a magic ball training device, including a base frame, a fixing mechanism at the outer triangular part of the base frame, and a connecting frame at the top of the three fixing frames of the three fixing mechanisms, and a ball is movably connected to the inner side of the connecting frame, and multiple sets of balls in contact with the ball are movably connected to the inner side of the connecting frame, and the balls play a role in limiting the movement of the ball.

[0006] The fixing mechanism also includes an arc-shaped sliding rod that slides inside the fixing frame, and a clamping arm is movably connected to the inner side of the arc-shaped sliding rod, and a clamping wheel is fixed at the end of the clamping arm;

[0007] The fixing mechanism also includes a sliding cavity, and the inner side of the sliding cavity serves to limit the pressure wheel when the pressure arm retracts. The fixing mechanism also includes a hinge seat and a torsion spring. The pressure arm and the arc-shaped sliding rod are movably connected through the hinge seat, and the torsion spring is located between the hinge seat and the pressure arm, which serves to provide an elastic rotational connection between the pressure arm and the hinge seat.

[0008] The innovative dynamic locking and intelligent control design significantly improves the stability and service life of the equipment, effectively solving the problem of wear caused by accidental rotation of traditional ball bearings. In terms of preventing accidental contact and wear control, when idle, the external rotor motor drives the clamping arm to extend the clamping wheel. The three sets of clamping wheels are in contact with the surface of the ball bearing through the elastic force of the torsion spring, and the ball bearing is locked by friction to prevent it from rotating unexpectedly due to vibration or collision. The friction frequency between the ball bearing and the connecting frame is reduced by more than 80%, which extends the service life of the ball bearing and the fixed frame, while ensuring the detection accuracy of the sensor.

[0009] The fixing mechanism also includes an external rotor motor, a gear, and an arc-shaped rack. The external rotor motor is installed inside the fixing frame, and the gear is fixed on the outside of the external rotor motor. The arc-shaped rack is fixed on the inner end of the arc-shaped sliding rod and meshes with the gear.

[0010] The base frame is equipped with a centralized control device, which is electrically connected to three sets of external rotor motors.

[0011] By adopting the above technical solution,

[0012] In summary, the present invention has the following main advantages:

[0013] 1. This utility model significantly improves the stability and service life of the equipment through innovative dynamic locking and intelligent control design, effectively solving the problem of wear caused by accidental rotation of traditional rolling balls. In terms of preventing accidental touch and wear control, when idle, the external rotor motor drives the clamping arm to extend the clamping wheel. The three sets of clamping wheels are in contact with the surface of the rolling ball through the elastic force of the torsion spring, and the friction force is used to lock the rolling ball, preventing it from rotating unexpectedly due to vibration or collision. The friction frequency between the rolling ball and the connecting frame is reduced by more than 80%, which extends the service life of the rolling ball and the fixed frame, while ensuring the detection accuracy of the sensor.

[0014] 2. In terms of interactive experience and control precision, the ball bearing structure inside the connecting frame allows the ball to rotate freely 360°. Combined with the built-in accelerometer and gyroscope, it can accurately capture data such as the rotation angle and acceleration of the ball in real time, ensuring the sensitivity and accuracy of interactive operation and improving the real-time feedback experience in games or training. In addition, the centralized control device realizes the automated management of locking and unlocking. It automatically locks when idle and intelligently unlocks when in use, reducing manual intervention and adapting to high-frequency use scenarios, further improving the intelligence level and ease of use of the device.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] The embodiments of this utility model will be described below based on its overall structure. Example

[0023] like Figure 1-5 As shown, this embodiment focuses on the magic ball training equipment. Its structural design focuses on ball fixing, dynamic limiting and intelligent control. It is mainly composed of a base frame 1, a fixing mechanism 2, a connecting frame 3 and a ball 4.

[0024] The base frame 1 adopts a triangular metal frame structure made of aluminum alloy. Anti-slip pads are installed at the bottom to ensure the stability of the equipment. The base frame 1 is equipped with a centralized control device 5, which is electrically connected to the external rotor motors 208 of the three sets of fixed mechanisms 2 through wiring to achieve unified control.

[0025] There are three sets of fixing mechanisms 2, which are respectively set at the outer triangle of the base frame 1. Each set of fixing mechanisms 2 includes a fixing frame 201, an arc-shaped sliding rod 203, a clamping arm 204 and a drive assembly.

[0026] The fixed frame 201 is fixed to the base frame 1, and a sliding cavity 202 is opened inside to accommodate the sliding of the arc-shaped sliding rod 203.

[0027] The arc-shaped sliding rod 203 is arc-shaped and is adapted to the sliding cavity 202 of the fixed frame 201. The inner end is fixed with an arc-shaped rack 210, and the outer side is connected to the clamping arm 204 through the hinge seat 206.

[0028] A pressure wheel 205 is installed at the end of the pressure arm 204. It is made of rubber with anti-slip texture on the surface. It is elastically connected to the hinge seat 206 through a torsion spring 207 and can rotate around the hinge seat 206.

[0029] The drive assembly includes an external rotor motor 208 and a gear 209. The external rotor motor 208 is fixed inside the fixed frame 201, and the gear 209 meshes with the arc-shaped rack 210 to drive the arc-shaped sliding rod 203 to slide arc-shaped along the sliding cavity 202.

[0030] The top of the three sets of fixing mechanisms 2 of the connecting frame 3 is fixed together to the inclined connecting frame 3. Multiple sets of stainless steel balls are embedded on the inner side. The balls are in contact with the surface of the ball 4 to form a rolling limit, allowing the ball 4 to rotate freely while restricting its lateral displacement.

[0031] The rolling ball 4 is a hollow sphere with a diameter of 30cm. Its surface is made of non-slip rubber material. It has a built-in accelerometer and gyroscope. It is connected to the centralized control device 5 via wireless signal and can transmit data such as rotation angle and acceleration in real time.

[0032] The status ball can be used for movement.

[0033] When the power supply of the centralized control equipment 5 is turned on, the power supply of the external rotor motor 208 is turned off, the arc-shaped sliding rod 203 drives the clamping arm 204 to retract into the fixed frame 201, and the clamping wheel 205 disengages from the surface of the ball 4.

[0034] The user pushes or tilts the ball 4, which rotates freely on the ball bearings of the connecting frame 3. The built-in sensor collects motion data such as rotation direction and angular velocity in real time, and transmits it to the centralized control device 5 via wireless signal to drive the movement of game characters or objects on the external display device, such as the screen.

[0035] Locked state to prevent accidental rotation

[0036] After use, the external rotor motor 208 is started by the centralized control device 5. The motor drives the gear 209 to rotate, which in turn drives the arc rack 210 and the arc sliding rod 203 to slide towards the ball 4.

[0037] The arc-shaped sliding rod 203 pushes the clamping arm 204 out of the fixed frame 201, and the torsion spring 207 elastically resets and drives the clamping arm 204 to flip toward the ball 4, so that the clamping wheel 205 fits against the surface of the ball 4.

[0038] Three sets of clamping rollers 205 simultaneously clamp the rolling ball 4, using the friction between the rubber roller and the ball to lock the rolling ball 4, preventing it from rotating due to vibration or collision, and reducing the frictional wear between the rolling ball 4 and the connecting frame 3.

[0039] Intelligent control and safety design

[0040] The centralized control device 5 integrates an automatic locking program. When the rolling ball 4 is detected to be stationary for more than 5 minutes, the external rotor motor 208 is automatically started to lock it. When a human body is detected to be approaching or an operation signal is detected, the lock is automatically released.

[0041] The elastic force of the torsion spring 207 has been optimized to provide sufficient locking force with a single clamping roller pressure of approximately 5N, while avoiding excessive compression that could damage the surface of the ball 4.

[0042] The working principle of this utility model is as follows: When in use, the power is turned on and the ball 4 is placed inside the three sets of fixing mechanisms 2. The top of the three sets of fixing mechanisms 2 is inclinedly fixedly connected to the connecting frame 3. The inner side of the connecting frame 3 has multiple sets of balls in contact with the ball 4, which plays a role in limiting the movement of the ball 4.

[0043] When the user pushes the ball 4, the sensor module built into the ball 4 wirelessly transmits data to the centralized control device 5, thereby identifying the rotation angle of the ball 4. This allows the user to control the characters and objects in the game on the display device by rolling the ball 4.

[0044] When not in use, the external rotor motor 208 built into each set of fixing mechanisms 2 starts. The external rotor motor 208 drives the arc rack 210 to slide in an arc shape through the gear 209. Then the arc rack 210 drives the arc sliding rod 203 to slide inside the sliding cavity 202. At this time, the end of the arc sliding rod 203 drives the pressing arm 204 and the pressing wheel 205 to extend. When the pressing wheel 205 extends out of the fixing frame 201, the torsion spring 207 performs a certain degree of reset, which in turn drives the pressing arm 204 to flip towards the position of the ball 4, so that the pressing wheel 205 at the end of the pressing arm 204 presses against the surface of the ball 4.

[0045] At this time, since the torsion spring 207 has not fully returned to its original position, the force of the torsion spring 207 causes the pressure wheel 205 to exert a certain pressure on the surface of the ball 4. Under the combined action of the three pressure wheels 205 and the friction between the pressure wheel 205 and the surface of the ball 4, the problem of the ball 4 rotating unexpectedly when not in use is avoided, thereby reducing the friction between the ball 4 and the connecting frame 3 and ensuring the overall detection accuracy and equipment stability.
