For ordinary skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0044] In an embodiment of the present application, referring to Figures 1-7 , a ball launching wheel is provided, including an inner wheel frame 211 and an outer wheel frame 216.

[0045] Among them, the inner wheel frame 211 is provided with a through hole 212, and the through hole 212 is rotatably connected to the mounting frame 220 through a connecting shaft. The periphery of the inner wheel frame 211 is provided with a ring of wheel frame part 213, and the peripheral wall of the wheel frame part 213 is concavely provided with a ring of accommodating groove 214, and the opposite two side walls of the accommodating groove 214 are both circumferentially provided with a plurality of insertion holes 215.

[0046] Among them, the opposite two side walls of the outer wheel frame 216 are both circumferentially provided with a plurality of insertion columns 217, the outer wheel frame 216 is adaptively connected to the accommodating groove 214, and the plurality of insertion columns 217 are respectively and one-to-one correspondingly inserted into the plurality of insertion holes 215.

[0047] Compared with the prior art, the one or more technical solutions of the ball launching wheel provided in the embodiments of the present application at least have one of the following technical effects:

[0048] Referring to Figure 3 and Figure 7 , the outer wheel frame 216 is connected to the wheel frame part 213 of the inner wheel frame 211 by the plurality of insertion columns 217 respectively and one-to-one correspondingly inserted into the plurality of insertion holes 215, and the connection is firm. Even if there is a crack in the outer wheel frame 216, since the plurality of insertion columns 217 are respectively and one-to-one correspondingly inserted into the plurality of insertion holes 215, the outer wheel frame 216 is not easy to fall off or burst open, and the use safety is improved, thereby greatly improving the use safety factor of the ball launching wheel 210.

[0049] Further, referring to Figure 3 and Figure 7The circumferential wall of the outer wheel frame 216 is provided with a plurality of protrusions 218, each of which is circumferentially arranged on the outer wheel frame 216. The height of the plurality of protrusions 218 decreases from the two sides to the middle of the circumferential wall of the outer wheel frame 216, so that the outer ends of the plurality of protrusions 218 are connected in an arc shape. Since the spherical surface is arc-shaped, when the ball launching wheel 210 rotates to launch the ball, the plurality of protrusions 218 are in full contact with the spherical surface, increasing the contact area (friction area) with the spherical surface and reducing the wear of the ball, thereby prolonging the service life of the ball.

[0050] Further, with reference to Figure 3 and Figure 7 Each of the plurality of protrusions 218 is provided with a plurality of protrusions 219 circumferentially spaced apart on the outer wheel frame 216. When the ball launching wheel 210 rotates to launch the ball, the protrusions 219 can be deformed to clamp (abut) the spherical surface of the ball to frictionally push the ball forward, and the outer wheel frame 216 further increases the friction between the plurality of protrusions 219 and the spherical surface of the ball, so that the ball launching force is increased and the ball is launched at high speed, which is beneficial to launching various types of change balls (such as spin balls and cut balls of table tennis).

[0051] Further, with reference to Figure 7 The inner wheel frame 211 is made of hard material such as metal or hard plastic, which enhances the strength of the inner wheel frame 211 and makes it less likely to deform or be damaged. The outer wheel frame 216 is made of soft or elastic material such as rubber or silicone, which is used to contact the spherical surface of the ball. When the ball launching wheel 210 rotates, the soft or elastic material of the outer wheel frame 216 can clamp the spherical surface of the ball and push it to rotate at high speed, which is better for launching the ball.

[0052] Further, with reference to Figure 7 The two through-holes 215 on opposite sides of the accommodating groove 214 are connected and form a communication groove 214a at the bottom of the accommodating groove 214, and the two through-poles 217 on opposite sides of the outer wheel frame 216 are connected and form a communication pole 217a on the inner wall of the outer wheel frame 216. A plurality of communication poles 217a are respectively accommodated in a plurality of communication grooves 214a, which increases the contact area between the outer wheel frame 216 and the accommodating groove 214, so that the outer wheel frame 216 is stably installed in the accommodating groove 214.

[0053] Further, the side wall of the inner wheel frame 211 is provided with a plurality of reinforcing ribs 211a, and the outer ends of the reinforcing ribs 211a are connected to the inner wall of the wheel frame 213, which improves the strength of the inner wheel frame 211 and makes it less likely to deform or be damaged.

[0054] Among them, with reference to Figure 7The outer wheel frame 216 and the wheel frame part 213 of the inner wheel frame 211 can be integrally formed by injection molding, and the outer wheel frame 216 and the wheel frame part 213 of the inner wheel frame 211 can also be bonded by glue, which is not limited herein.

[0055] In another embodiment of the present application, a multi-wheel ball launcher is also provided, which comprises a ball launching pipe 100, a ball launching mechanism 200 and a ball feeding pipe 300.

[0056] Wherein, referring to Figures 1-3 The ball launching pipe 100 has a ball launching channel 110, and the two ends of the ball launching channel 110 are respectively a ball outlet end 101 and a ball inlet end 102. A plurality of openings 120 are arranged along the circumference of the outer wall of the ball launching pipe 100, and the openings 120 are connected to the ball launching channel 110.

[0057] Wherein, referring to Figures 1-3 A plurality of ball launching mechanisms 200 are arranged one-to-one corresponding to the plurality of openings 120. The ball launching mechanism 200 comprises a ball launching wheel 210, a mounting bracket 220 and a driving unit 230. The mounting bracket 220 is fixedly arranged on the ball launching pipe 100, and the driving unit 230 is fixedly arranged on the mounting bracket 220. The output end of the driving unit 230 is connected to the center of the ball launching wheel 210 for driving the ball launching wheel 210 to rotate. Each ball launching wheel 210 at least partially penetrates through an opening 120 and extends into the ball launching channel 110, and the peripheral walls of the plurality of ball launching wheels 210 form a ball launching position in the ball launching channel 110. When the plurality of ball launching wheels 210 rotate, each ball surface of the ball at the ball launching position is rubbed to push the ball to be shot outward.

[0058] Wherein, referring to Figure 1 And Figure 2 One end of the ball feeding pipe 300 is connected to the ball inlet end 102, and the other end of the ball feeding pipe 300 is connected to a ball feeding mechanism 400.

[0061] Referring to Figures 1-3Multiple drive units 230 independently drive multiple serving wheels 210 to rotate, so that the speed of each serving wheel 210 is different. This allows the multiple serving wheels 210 to rub the different surfaces of the ball at the serving position at different speeds, so as to push the ball out from the ball outlet 101 and launch various different types of balls (such as the spin ball or the high-difficulty ball such as the slice ball in table tennis). This makes the ball serving machine's serving more similar to the way a real person serves, so as to satisfy the training interest of athletes and achieve the training effect desired by trainees, thereby improving their ball skills.

[0062] The drive unit 230 is a drive motor that drives the serving wheel 210 to rotate. For example, the drive motor can be a speed-regulating motor, so that the speed of the serving wheel 210 can be adjusted. Thus, the speed of multiple serving wheels 210 can be different according to the serving requirements, so as to launch various different types of balls.

[0063] Furthermore, referring to Figures 1-3 The mounting bracket 220 is a housing, covering the opening 120.

The middle part of the ball clamping baffle 460 is rotatably provided on the pipe wall of the ball guiding pipe 440 by a connecting rod 461, and the ball clamping baffle 460 is provided with an elastic member (not shown in the figure). The elastic member is used to drive one end of the ball clamping baffle 460 to extend into the ball guiding pipe 440 from the slot 443 and hold the lower side of the ball, so as to prevent the ball from falling downward and causing noise. When the ball moves along the ball guiding pipe 440, the ball clamping baffle 460 is pushed and tipped outward to pass over the ball clamping baffle 460, so that the ball can only move upward along the ball guiding pipe 440.

[0091] The elastic member can be a compression spring or a torsion spring.

[0092] The remaining parts of the embodiment are the same as those of the first embodiment. The features not explained in the embodiment are explained in the first embodiment, and will not be described here.
