[0023] The specific implementation of the utility model will be described below in conjunction with the accompanying drawings:

[0024] like Figures 1 to 6As shown, a badminton serving device for teaching comprises a dribbling mechanism 1, a serving mechanism 2 and a support frame 3. The ball outlet end 112 of the dribbling mechanism 1 is passed into the serving mechanism 2, and the serving mechanism 2 is rotatably connected to the support frame 3. The dribbling mechanism 1 comprises a ball storage tube 11 and a driving mechanism 13, and the driving mechanism 13 comprises a conical top block 137, a straight rod 133 and a screw rod 132, the conical top block 137 is fixedly connected to one end of the straight rod 133, and the other end of the straight rod 133 is threadedly connected to the screw rod 132, and a dribbling motor 131 is provided at the end of the screw rod 132. The dribbling motor 131 drives the screw rod 132 to rotate, and the screw rod 132 drives the straight rod 133 to move, and the conical top block 137 pushes the badminton to move toward the ball outlet end 112 in the ball storage tube 11. The ball storage tube 11 is provided with a side cover 12, one side of the side cover 12 is connected to the ball storage tube 11 through a hinge, and the other side is connected to the ball storage tube 11 through a push-type buckle 113. The hinged side cover 12 is convenient for freely opening and closing the ball storage tube 11, and the side cover 12 is locked or opened by the push-type buckle 113. A perspective window 122 is provided on the side cover 12, and a handle 121 is provided on the side of the side cover 12 away from the hinge. The handle 121 facilitates the operation of the opening and closing state of the side cover 12, and the transportation state of the badminton in the ball storage tube 11 can be observed through the perspective window 122.

[0025] The ball outlet end 112 is a conical outlet, and the ball outlet end 112 cooperates with the cone to keep the badminton in the ball storage tube 11 stable in radial direction. When the badminton shakes radially, the badminton is stuck in the ball storage tube 11. The badminton is driven to be discharged by mechanical driving, which strengthens the control of the badminton and prevents the badminton from being stuck. The conical top block 137 is fixedly connected to the upper end of the straight rod 133 through the extension rod 136. The extension rod 136 facilitates the conical top block 137 to discharge the badminton in the ball storage tube 11, thereby improving the efficiency of discharging the badminton. The upper end of the straight rod 133 is located in the ball storage tube 11, and the straight rod 133 is slidably connected to the ball storage tube 11. The ball storage tube 11 is provided with a slide groove 114 that matches the straight rod 133, and the slide groove 114 is connected to the ball storage tube 11 and the bottom bin 111. The straight rod 133 is provided with a ball 134, and the slide groove 114 is provided with a track that matches the ball 134. The ball bearing 134 is used to reduce the friction between the straight rod 133 and the slide groove 114. A bottom bin 111 is provided below the ball storage tube 11, and the screw rod 132 and the ball dribbling motor 131 are located in the bottom bin 111. Placing the screw rod 132 and the ball dribbling motor 131 in the bottom bin 111 improves the overall integration of the device, enables the screw rod 132 to work in a relatively closed and clean environment, and provides certain protection for the screw rod 132 and the ball dribbling motor 131.

[0026] The serving mechanism 2 includes a housing 21 and a steering mechanism. One side of the housing 21 is provided with an opening 211 that matches the ball outlet end 112, and the other side is provided with a serving tube 212 corresponding to the ball outlet end 112. Both sides of the ball outlet end 112 are provided with U-shaped ejection wheels 22. The side of the U-shaped ejection wheel 22 has a large contact area with the head of the badminton, which can provide greater friction to eject the badminton into the serving tube 212. The U-shaped ejection wheels 22 are respectively equipped with ejection motors 221, and each U-shaped ejection wheel 22 is equipped with an ejection motor 221, which is convenient for improving the output power of the ejection motor 221 and providing sufficient power for ejecting the badminton. The ejection motor 221 drives the U-shaped ejection wheel 22 to rotate. The head of the badminton is discharged from the ball outlet 112 and enters between the U-shaped ejection wheels 22. The U-shaped ejection wheels 22 apply a squeezing force and a friction force to the head of the badminton, so that the badminton is separated from the ball outlet 112 and enters the serving tube 212, and finally ejected from the housing 21 from the serving tube 212. A freely openable and closable door 213 is provided on one side of the housing 21. Opening the door 213 facilitates maintenance of components in the housing 21.

[0027] The bottom of the housing 21 is provided with a steering mechanism, which includes a rotating disk 23 and a steering motor 234. A projection 231 is provided on the top of the rotating disk 23, and the projection 231 is rotatably connected to the bottom surface of the housing 21 through a damping shaft, and a tightening knob 232 is provided on one side of the damping shaft. By adjusting the tightness of the tightening knob 232, the relative angle between the housing 21 and the rotating disk 23 can be changed, thereby adjusting the elevation angle of the badminton ejected. The bottom surface of the rotating disk 23 is rotatably connected to the support frame 3, and the support frame 3 is provided with a steering motor 234, and the rotation center of the rotating disk 23 is fixedly connected to the output shaft of the steering motor 234. The steering motor 234 changes the horizontal angle of the rotating disk 23, thereby adjusting the horizontal angle of the ejected badminton.

[0028] The support frame 3 includes a chassis 31 and a support leg. A pressure bearing 233 is provided between the chassis 31 and the steering mechanism. The output end of the steering motor 234 passes through the through hole 311 on the chassis 31 and is fixedly connected to the turntable 23. The pressure bearing 233 can reduce the friction between the chassis 31 and the housing 21. A plurality of support legs are evenly spaced on the circumference of the chassis 31. The support legs include a telescopic rod 32, a fixed knob 321 and a cushion block 322. One end of the telescopic rod 32 is rotatably connected to the bottom plate 135 through a first rotating shaft 312. The first rotating shaft 312 is used to change the angle of the support leg, and the vertical height of the serving mechanism 2 and the dribbling mechanism 1 is changed by combining the telescopic characteristics of the telescopic rod 32. A fixed knob 321 is provided on the telescopic rod 32. One end of the fixed knob 321 passes through the telescopic rod 32. The elongation of the telescopic rod 32 can be adjusted by adjusting the tightness of the fixed knob 321. The other end of the telescopic rod 32 is rotatably connected to the cushion block 322 via the second rotating shaft 323. The angle between the cushion block 322 and the telescopic rod 32 is variable by the second rotating shaft 323, so that the supporting legs can adapt to different ground conditions. The telescopic and foldable supporting legs make the device easy to store.

[0029] The working principle of the specific embodiment of the utility model is as follows: open the side cover 12, place a plurality of stacked badmintons in the ball storage tube 11, with the head of the badminton facing the ball outlet end 112, and the conical top block 137 located in the tail of the badminton. Start the ejection motor 221 to rotate the U-shaped ejection wheel 22. Then start the ball dribbling motor 131, the screw rod 132 drives the conical top block 137 to move, and the conical top block 137 pushes the badminton to move toward the ball outlet end 112. The head of the badminton is exposed from the ball outlet end 112, and under the action of the U-shaped ejection wheel 22, the badminton is separated from the ball outlet end 112 and ejected out of the housing 21 through the ball serving tube 212.
