[0010] The present invention specifically adopts the following technical solutions:

[0011] The multifunctional badminton of the present invention comprises a ball head and a ball skirt, wherein the lower end of the ball skirt is connected to the ball head, the inner diameter of the ball skirt gradually increases from bottom to top, the ball skirt comprises a rib section and a guide section, the rib section is composed of a plurality of rib bodies, a plurality of mesh holes are provided in the guide section, the lower end of the guide section is connected to the rib section, and the upper end of the guide section is bent outward in an arc shape to form a bending portion for increasing wind resistance.

[0012] As a further preferred embodiment of the present invention, a connecting plate is provided at the lower end of the rib segment, an annular positioning ring is provided at the lower end of the connecting plate, a positioning groove which is matched with the positioning ring is provided at the upper end of the ball head, and a rotating drive assembly is provided on the connecting plate.

[0013] As a further preferred embodiment of the present invention, the side wall of the positioning ring is provided with a first annular half groove, the inner wall of the positioning groove is provided with a second half groove aligned with the first half groove, the first half groove and the second half groove are buckled to form a ball groove, and the ball groove is filled with a ball body.

[0014] As a further preferred embodiment of the present invention, a connecting hole interconnected with the ball groove is formed through the outer wall of the ball head, the ball body enters the ball groove through the connecting hole, and a fixing block is threadedly connected to the connecting hole.

[0015] As a further preferred embodiment of the present invention, the rib bodies are in the shape of long strips, all the rib bodies are distributed in a circular array, and the distances from both sides of the rib bodies to the center of the circle formed by all the ribs are unequal.

[0016] As a further preferred embodiment of the present invention, the ball skirt is further provided with reinforcement ribs, and the reinforcement ribs are interconnected with all rib bodies.

[0017] As a further preferred embodiment of the present invention, the rotary drive assembly includes a motor, a driving wheel, a driven wheel and a rotating shaft; the ball head is a hollow structure, the motor is arranged inside the ball head, the driving wheel is sleeved on the output shaft of the motor, the upper end of the rotating shaft is connected to the center of the lower end of the connecting plate, the driven wheel is sleeved on the rotating shaft, and the driving wheel and the driven wheel are meshed with each other.

[0018] As a further preferred embodiment of the present invention, the ball head includes an upper shell and a lower shell, a first groove is formed at the lower end of the upper shell, a second groove is formed at the upper end of the lower shell, and the first groove and the second groove are buckled to form a hollow structure.

[0019] As a further preferred embodiment of the present invention, the upper shell and the lower shell are threadedly connected.

[0020] As a further preferred embodiment of the present invention, a distance sensor is arranged inside the ball head.

[0021] The beneficial effects of the present invention are embodied in:

[0022] 1. The present invention provides a bending portion for increasing wind resistance at the upper end of the ball skirt, and the appearance is mushroom-cloud-shaped. The force-bearing area of ​​the badminton is increased, which can increase the wind resistance of the badminton during movement and reduce the movement speed of the badminton to adapt to the elderly, children and other groups.

[0023] 2. By setting a connecting plate, a rotating drive assembly is set at the lower end of the connecting plate. When the motor is working, the driving wheel mounted on the output shaft drives the driven wheel to rotate, thereby realizing the rotation of the connecting plate. The ball skirt is installed on the connecting plate as a whole, and the ball skirt as a whole can rotate with the connecting plate. It should be noted that: due to the heavy head of the ball, about 90% or more of the time during the movement of badminton is the ball head impacting the airflow. Even if the badminton is not impacted by the ball head at the beginning, it will quickly adjust to the state of head impact during the movement. The shape of the rib body is long and narrow, and the distances from the two sides of the rib body to the center of the circle are not equal, that is, all the rib bodies are inclined in a clockwise or counterclockwise direction. During the rotation of the ball skirt, the airflow passes through the drainage effect of the ribs, generating a backward reaction force, which further achieves the effect of reducing the ball speed.

[0024] 3. A distance sensor, an external type-c charging interface, a system switch and a gear position are arranged in the cavity structure of the ball head. When the distance sensor switch is turned on and the distance sensor starts working, the badminton will not immediately generate a reaction force. Only when an obstacle approaches the badminton, the distance sensor will issue a command to the small motor to drive the ball skirt to rotate, thereby generating a reaction force. When the distance sensor is not turned on, it can be used as an ordinary slow-speed badminton, which can be used by the elderly, children and beginners. The distance sensing system is divided into two gears. The reaction force of gear I is relatively weak, which is used for fun badminton sports and can be used by people who pursue the diversity and fun of badminton sports; the reaction force of gear II is relatively strong, and it can be used independently as a sensing aircraft for children and electronic product enthusiasts. Distance sensors include ultrasonic distance sensors, laser distance sensors, infrared distance sensors and 24GHz radar sensors, and ultrasonic sensors are preferred. Ultrasonic waves have great ability to penetrate liquids and solids, especially in solids that are opaque to sunlight. When ultrasonic waves hit impurities or interfaces, they will produce significant reflections to form echoes, and when they hit moving objects, they can produce the Doppler effect. When the distance sensor senses an obstacle, it will send a command to the small motor to drive the ball skirt to rotate, thereby generating a reaction force on the moving object. The speed of gear I is slower and the reaction force is weaker; the speed of gear II is faster and the reaction force is stronger.

[0025] 4. By setting a ball groove and filling the ball body in the ball groove, the connecting plate is limited, the connection plate and the ball head are kept in one piece, and the rotation process of the connecting plate is not affected. By setting a connecting hole and the connecting hole is threaded with a fixing block, the filled ball body is limited, ensuring that the connecting plate can rotate smoothly and is easy to disassemble and install.

[0026] 5. The ball head includes an upper shell and a lower shell. The lower shell is made of small-grain cork, the second shell is made of Taiwan fiber, and the ball skirt is made of ordinary plastic. The first groove and the second groove are provided to facilitate the placement of the motor and the distance sensor. The upper shell and the lower shell are connected by body threads, which is convenient for disassembly and installation.

[0027] 6. The badminton has three main uses: 1. It can be used as an ordinary slow-speed badminton; 2. It can be used as an interesting badminton to increase the reaction force during the badminton movement, change the trajectory and speed of the badminton, thereby interfering with the athlete's judgment, increasing the fun of the sport itself and the uncertainty of the game results; 3. It can be used as an induction aircraft. The badminton can be separated from the badminton racket and used alone as an induction aircraft toy. BRIEF DESCRIPTION OF THE DRAWINGS

The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0036] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0037] Example 1

[0038] The multifunctional badminton of the present invention comprises a ball head 1 and a ball skirt 2, wherein the lower end of the ball skirt 2 is connected to the ball head 1, the inner diameter of the ball skirt 2 gradually increases from bottom to top, the ball skirt 2 comprises a rib segment 201 and a guide segment 202, the rib segment 201 is composed of a plurality of rib bodies 2011, the guide segment 202 is provided with a plurality of mesh holes, the lower end of the guide segment 202 is connected to the rib segment 201, and the upper end of the guide segment 202 is bent outward in an arc shape to form a bending portion 3 for increasing wind resistance.

[0039] After adopting the above technical solution: the present invention sets a bending portion 3 for increasing wind resistance at the upper end of the ball skirt 2, and the appearance is mushroom cloud-shaped. The force-bearing area of ​​the badminton is increased, which can increase the wind resistance of the badminton during movement and reduce the movement speed of the badminton to adapt to the elderly, children and other groups.

[0041] This embodiment is further optimized on the basis of the embodiment 1 as follows: a connecting plate 4 is provided at the lower end of the rib segment 201, a ring-shaped positioning ring 6 is provided at the lower end of the connecting plate 4, a positioning groove adapted to the positioning ring 6 is provided at the upper end of the ball head 1, and a rotation drive assembly 5 is provided at the connecting plate 4. The rib body 2011 is in the shape of a long strip, and all the rib bodies 2011 are distributed in a ring array, and the distances from both sides of the rib body 2011 to the center of the circle formed by all the ribs are not equal. The ball skirt 2 is also provided with a reinforcing rib 11, and the reinforcing rib 11 is connected to all the rib bodies 2011.

[0042] After adopting the above technical solution: by setting the connecting plate 4, the lower end of the connecting plate 4 is provided with a rotating drive assembly 5. When the motor 501 works, the driving wheel 503 sleeved on the output shaft 502 drives the driven wheel 504 to rotate, thereby realizing the rotation of the connecting plate 4. The ball skirt 2 is installed on the connecting plate 4 as a whole, and the ball skirt 2 can rotate with the connecting plate 4 as a whole. It should be noted that: because the ball head 1 is heavy, the ball head 1 impacts the airflow for about 90% or more of the time during the movement of the badminton. Even if the badminton is not impacted by the ball head 1 at the beginning, it will quickly adjust to the state of head impact during the movement. The shape of the rib body 2011 is long strip, and the distances from the two sides of the rib body 2011 to the center of the circle are not equal, that is, all the rib bodies 2011 are inclined in the clockwise or counterclockwise direction. During the rotation of the ball skirt 2, the airflow passes through the drainage effect of the ribs, generating a backward reaction force, further realizing the effect of reducing the ball speed.

[0043] Example 3

[0044] This embodiment is a further optimization based on the embodiment 1 as follows: a distance sensor 12 is arranged inside the ball head 1 .

When the distance sensor 12 switch is turned on, the distance sensor starts to work, and the badminton does not immediately generate a reaction force. Only when an obstacle approaches the badminton, the distance sensor will issue an instruction to the small motor 501 to drive the ball skirt 2 to rotate, thereby generating a reaction force. When the distance sensor is not turned on, it can be used as an ordinary slow badminton, which can be used by the elderly, children and beginners. The distance sensing system is divided into two gears, the I gear has a weak reaction force, which is used for fun badminton sports, and can be used by people who pursue the diversity and fun of badminton sports; the II gear has a strong reaction force, which can be used independently as a sensing aircraft for children and electronic product enthusiasts. The distance sensor includes an ultrasonic distance sensor, a laser distance sensor, an infrared distance sensor and a 24GHz radar sensor, and an ultrasonic sensor is preferably used. Ultrasonic waves have great ability to penetrate liquids and solids, especially in solids that are opaque to sunlight. When ultrasonic waves hit impurities or interfaces, they will be reflected significantly to form echoes, and when they hit moving objects, they can produce Doppler effect. When the distance sensor senses an obstacle, it will send a command to the small motor 501 to drive the ball skirt 2 to rotate, thereby generating a reaction force on the moving object. The speed of gear I is slower and the reaction force is weaker; the speed of gear II is faster and the reaction force is stronger.
