Description

[Technical field]

[0001] This utility model relates to the technical field of table tennis training equipment, and more particularly to a self-training device for returning various hits in table tennis. [Background technology]

[0002] Enthusiasts who want to learn and improve their table tennis skills can only learn and improve their table tennis skills by going to places like table tennis stadiums and hiring a coach. Table tennis training equipment currently on the market includes table tennis rebound boards, landing soft shaft swing table tennis trainers, table side bending spring table tennis trainers, and some table tennis enthusiasts stand next to the table tennis table and hold the ball to the left. After releasing the hand, the ping pong ball naturally falls vertically and bounces up vertically, and the right hand holds the racket to hit the ball. The "serve" method of these methods is far from the real serve effect, too simple and simple, and the practice effect is greatly limited. In addition, table tennis enthusiasts pay a lot of money to hire trainers or buy serve machines. Due to the limitations of the stadium, only places like table tennis stadiums and training centers can be realized. There are also problems with the cost and time of transportation from home or office to table tennis halls and training centers.

[0003] In conclusion, existing table tennis training equipment has limitations on the playing field, poor flexibility in use, and is difficult to adapt to different training scenarios and high training costs. Summary of the Invention [Problem to be solved by the invention]

[0018] Specific implementation method In order to more clearly explain the embodiments of the present utility model and the technical solutions in the existing technology, the following briefly introduces the present utility model by combining the attached drawings with the embodiments or the description of the existing technology. Obviously, the structural descriptions in the following attached drawings are only some embodiments of the present utility model. For those of ordinary skill in the art, other appended drawings can be obtained based on these attached drawings without creative work. It should be noted here that the description of these embodiment methods is helpful for understanding the present utility model, but is not a limitation on the present utility model.

[0019] As shown in Figures 1 to 22, this embodiment provides a self-training device for hitting various types of balls in table tennis. It comprises a rebound plate 1, a support plate 2 and a damping hinge 3. A first end plate of the damping hinge 3 is fixedly connected to one end of the support plate 2, and a second end plate of the damping hinge 3 is fixedly connected to one end of the rebound plate 1, and the damping hinge 3 can be rebounded.

[0020] In this technical solution, the first end plate of the damping hinge 3 is fixedly connected to the end of the support plate 2, and the second end plate of the damping hinge 3 is fixedly connected to one end of the backboard 1. The damping hinge 3 is installed between the rebound plate 1 and the support plate 2. The damping hinge 3 can be placed at any height suitable for practice between the rebound plate 1 and the support plate 2, so that training is possible and there are no restrictions on the usage scenario. This technical solution has a simple structure, low cost, easy portability, more flexible use, and high practicality.

[0021] The deflection plate 1 and the support plate 2 are connected by the damping hinge 3, which maintains a sufficiently strong fixed angle between the deflection plate 1 and the support plate 2 with sufficient damping force. If the manual striking force is greater than the damping force, the included angle θ between the deflection plate 1 and the support plate 2 will fluctuate.

[0022] Preferably, the inclination angle of the deflection plate 1 is fixed, and the damping hinge 3 is selected to have a damping torque of 1.0-1.8Nm and weight so that the inclination angle can be easily adjusted, and can be operated by an appropriate person. As shown in Figures 7 and 8, in the case of a tabletop type, when the left and right continuous position angle swing mechanism 6 is not adopted, the second end plate of the damping hinge 3 and the end of the deflection plate 1 are fixedly connected, and the first end plate of the damping hinge 3 and the support plate 2 are manufactured as an integrated unit, which simplifies the manufacturing procedure and cost without compromising the performance of use. It also reduces the volume (thickness) of the product.

[0023] Example 2: This embodiment is optimized based on the above embodiment 1. As shown in Figures 2 and 4, a left-right continuous position angle swing mechanism 6 is also included, which is installed on a support plate 2, a driven end of the left-right continuous position angle swing mechanism 6 is fixedly connected to a first end plate of a damping hinge 3, and the left-right continuous position angle swing mechanism 6 drives the rebound plate 1. A continuous swing angle P is provided in the left-right direction from the rebound plate 1 to the support plate 2. The left-right continuous position angle swing mechanism 6 is designed to increase the randomness of the return after hitting, and the randomness of the return randomly generates serves and counterattacks of various courses, maximally approximating the actual state of table tennis.

[0024] The left-right continuous position angle swing mechanism 6 drives the left-right continuous swing angle P of the deflection plate 1 and support plate 2, and the maximum angle (swing angle P) for swinging to the left and right is 38 degrees. As shown in Figure 22, taking a right-handed grip as an example, swinging to the left will result in a backhand serve, a hit (return), and a backhand shot, while swinging to the right will result in a forehand serve, a hit, and a forehand shot. When the left-right continuous position angle swing mechanism 6 generates a continuous swing action, the surface of the deflection plate 1 swings at a continuous angle, and serves and hits can be made by the left and right hands from various position angles.

[0025] It should be explained that if there is no left and right continuous position angle swing mechanism 6, the device can be manually swung to the left or right to the appropriate position. As shown above, swinging to the left produces backhand serve, counter and backhand shot, and swinging to the right produces forehand serve, counter and forehand shot. The forehand and backhand training effects can be achieved in the same way.

[0026] Example 3: This embodiment is optimized based on the above embodiment 2. As shown in Figure 3-6, in order to make it easier to see the specific structure of the left and right continuous position angle swing mechanism 6, the bounce plate 1 is adjusted to a vertical state, and the bounce plate 1 can be adjusted to an inclined state during use without affecting the understanding. To provide a specific left and right continuous position angle swing mechanism 6, the left and right continuous position angle swing mechanism 6 includes a DC motor 7, a rotating plate 8, an eccentric convex shaft 9 and a sliding swing plate 10, the DC motor 7 is mounted on the support plate 2, the output shaft of the DC motor 7 is connected to the rotating plate 8, and the rotating plate 8 is fixed to the eccentric convex shaft 9. One end of the sliding swing plate 10 and the support plate 2 are connected to the rotating connection position 23, the other side of the sliding swing plate 10 has a sliding slot 24, the eccentric convex shaft 9 is in the sliding slot 24, and the end of the sliding swing plate 10 close to the sliding slot 24 is fixedly connected to the first end plate of the damping hinge 3.

[0027] After the DC motor 7 is energized, it drives the turntable 8, which rotates the eccentric convex shaft 9, which continuously swings the sliding swing board 10 at the rotation connection position 23, and the sliding swing board 10 continuously swings the bounce board 1 at a fixed angle by the damping hinge 3, realizing the left and right connection. The angle of the continuous position is the swinging effect.

[0028] Example 4: This embodiment is optimized based on the above embodiment 1 or 2. As shown in Figures 9 and 10, in order to facilitate training and use without tabletop support, the ground support frame 11 and the support plate 2 are placed on the ground support frame 11, or the upper ends of the support plate 2 and the ground support frame 11 are also magnetically attracted to each other.

[0029] Example 5: This embodiment is optimized based on the above embodiment 4. In order to facilitate adjusting the ground support frame 11 to an appropriate height position, the ground support frame 11 includes a manual lifting rod, which is a variety of manually driven lifting structures, all of which are existing technologies and will not be limited here.

[0030] Example 6: This embodiment is optimized based on the above embodiment 4. In order to facilitate the stable and detachable installation of the support plate 2 and the ground support frame 11, the second suction device 13 is installed at the bottom of the support plate 2, the first suction device 12 is installed at the top end of the ground support frame 11, and the first suction device 12 and the second suction device 13 are installed at the top end of the ground support frame 11. The first suction device 12 and the second suction device 13 are both magnets.

[0031] This self-practice device can be selected from two types: a table type device (without ground support frame 11) or a ground type device (with ground support frame 11). The switch between the table type device and the ground type device is completed by attaching and detaching the first suction device 12 and the second suction device 13, which are respectively provided on the top of the ground support frame 11 and the bottom of the support plate 2. The table type can be easily switched to the ground type, and the ground type can also be easily switched to the tabletop type, and manual separation and installation are convenient and convenient.

[0032] Example 7: This example is optimized based on Example 1 above. In order to produce various types of serves and returns, the bounce board 1 can be a flat plate, a round-bottomed spherical panel 15 or a square-bottomed arc-shaped plate 16, the round-bottomed spherical panel 15 includes a circular base plate and a spherical surface integrally formed with the circular base plate, and the square-bottomed arc-shaped plate 16 is a square plate. The flat plate is a flat rectangular plate or a flat circular or elliptical plate.

[0033] The size of a good flat square board or square bottom board is width 100~180mm, optimal 150mm, length 150~250mm, optimal 200mm, and the diameter of the circular bottom board of a good round bottom ball panel 15 is 150~250mm, optimal 180mm. The optimal size should not affect the normal running line of the ball after hitting, and should not affect the ball falling well on the impact surface to form the serve and return path after being thrown with the left hand, and at the same time, should take into consideration the convenience of carrying and storing the tabletop device.

[0034] Example 8: This example is optimized based on Example 1 above. As shown in Figure 15, in order to integrate various training modes, the bounce board 1 has two panels 17, the two panels 17 are the left panel 17.1 and the right panel 17.2, and the angle between the left panel 17.1 and the right panel 17.2 is obtuse. The two panels 17 have two board surfaces for forehand and backhand serve and re-batting, which realizes the training effect of forehand and backhand serve and re-batting and re-batting and shot.

[0035] Example 9: This embodiment is optimized based on the above embodiment 1. As shown in Figure 13 and Figure 14, in order to integrate more training modes, the bounce board 1 has three panels 18, the three panels 18 include a middle board 18.1 and two side boards 18.2, and the angle between the two side boards 18.2 and the middle board 18.1 is an obtuse angle.

[0036] Three Panel 18 also has two board surfaces for forehand and backhand serve and return, which realizes the ball training effect of forehand and backhand serve, return and shot. In addition, the middle board 18.1 of Three Panel 18 can also train mid-ball. In summary, Three Panel 18 can train forehand ball, mid-ball, backhand ball consecutively, or any combination of three-way ball consecutively, making the training extremely close to the climax of real battle.

[0037] Example 10: This example is optimized based on Example 9 above.

[0038] In order to arbitrarily select the connection method between the two side boards 18.2 and the middle board 18.1 as required, the two side boards 18.2 and the middle board 18.1 are integrally molded, as shown in Figure 14. Alternatively, as shown in Figure 13, a removable button 19 is installed between the left and right sides of the two side boards 18.2 and the middle board 18.1, which can manually adjust the angle between the middle board 18.1 and the support board 2, and simultaneously change the clip angle between the two side boards 18.2, the middle board 18.1 and the support board 2, and change the inclination angle of the rebound board surface of the two side boards 18.2 and the middle board 18.1. When training, the position of the self-training device can be manually changed (as shown in Figure 22), which can form the training effect of forehand serve and rebound and backhand serve and rebound serve and rebound. This multi-board rebound board is only used in table style.

[0039] This technical solution designs two panels 17, three panels 18 or left and right continuous position angle swing mechanism 6 to generate trajectories and rebounds for hitting the ball with the left and right hands, and the swing angle (swing angle P) ranges from 0 to 38 degrees (generating a backhand ball) and 0 to -38 degrees (generating a forehand ball). In addition, when the rebound plate 1 is a flat plate and there is no left and right continuous position angle swing mechanism 6, the position of the rebound plate 1 can be manually moved to adjust the swing angle P.

[0040] The aforementioned forehand and backhand hitting training is taken as an example of holding the racket in the right hand. Swinging the table-type device in the left hand shifts the position to the left, resulting in a backhand serve, return hit, and backhand shot, and swinging it in the right hand shifts it to the right, resulting in a forehand serve, return hit, and forehand shot.

[0041] As shown in FIG. 16, the position of the table type device on the table tennis table 20 can be changed, and one table type device can be installed on the table tennis table 20, or multiple table type devices can be installed to perform different mode training consecutively.

[0042] As shown in Figure 16, the table-top device and the landing device are positioned during the training of long ball serves and counterattacks. When there is a table and no table, the landing device can realize the long ball serves and the counterattack effect of the forehand and backhand. When there is no table, the table-top device can also realize the long ball serves and the counterattack effect and the long ball hit effect of the forward and reverse hand. Just place the bounce board 1 on the table at the same height as the table.

[0043] When the swing angle is set at a fixed point in front or behind the table or at a fixed point in a far or near position on the ground, the manual or electric swing angle is in the range of 0~38 degrees (backhand ball occurs), 0~-38 degrees (forehand ball occurs). The serve occurs when the swing angle is close to 0 degrees, the ball is closer to the middle ball, and the larger the swing angle of the rebound plate 1, the more difficult the forehand and backhand posture for the serve and rebound becomes, and the hitting motion is most standardized so that the hitter moves sideways or left and right, resulting in the best hitting effect.

[0044] In the above embodiment, the material of the deflection plate 1 can be selected from hard materials that are non-toxic, non-corrosive, non-irritating and odorless, and safe for users, such as hard wood, acrylic, electric wood or metal aluminum, and the surface of the deflection plate 1 is flat and finely bristled.

[0045] Specific usage example: Take the ball in your left hand, throw it back onto the board, and hold the racket in your right hand to hit the ball. According to the conventions of daily table tennis, after the opponent serves, the ball falls on your own side of the table 20, resulting in the following ball path type. See Figure 17. The specific ball path type in the figure is as follows: Table 1 TIFF0003249676000002.tif80135

[0046] Training method 1: Using the table-type device of the first embodiment (without the left-right continuous position angle swing mechanism, table-type manual device), for example, taking a backhand ball as an example, the inclination (angle O) of the bounce board 1 plate surface is manually adjusted to an appropriate angle, and the table-type manual device is manually placed on the table tennis table at positions 13, 14 or 15 in FIG. 17. To receive a forehand ball sent by the "opponent", the player manually moves the table-type manual device on the table tennis table to swing it to the right and swings the bounce board 1 plate surface at an appropriate angle (swing angle P), stands at an appropriate position on the hitting side of the opponent's table 20, holds a ball in the left hand, and throws the ball at the bounce board 1. The table tennis ball is ejected to the left hand side by the surface of the bounce board 1, completing a backhand serve and return from the opponent, and the opponent holding a racket in the right hand hits the ball with a backhand push block, backhand twist pull, etc. To receive a forehand ball from the "opponent", all one needs to do is manually move the table-type manual device on the table and swing it to the right hand side. To take a forehand ball from the "opponent," the player manually moves the table-type manual device on the table, swings the ball to the right side of the board of the rebound board 1 at an appropriate angle (swing angle P), and, keeping the body in place, holds the ball in the left hand and throws the ball at the rebound board 1. The table tennis ball is shot back to the right side of the board, which corresponds to the "opponent" completing a serve and return to the opponent's forehand, and the opponent holds the racket in his right hand and hits the shot ball into the opponent's table 22 with a forehand cross push or forehand pull.

[0047] Training method 2: In the table-type device of the second embodiment (the left-right continuous position angle swing mechanism 6, abbreviated as the table-type electric device), for example, the inclination (angle θ) of the plate surface of the bounce plate 1 of the table-type electric device is adjusted manually to an appropriate angle, and then the table-type electric device is manually placed at positions 9, 10 or 11 on the table in Fig. 17, and the table-top electric unit is energized, and the bounce plate 1 starts to swing back and forth at a uniformly slow and continuous speed from left to right or right to left within the range of +38 degrees to -38 degrees in position angle, and the player stands alone at an appropriate position on the hitting side of the table tennis table 20. Holding a ball in the left hand, the player throws the ball onto the surface of the bounce plate 1, and the table tennis ball is returned to the left or right side of the teammate or the center of the court and shot out depending on the surface of the bounce plate 1 at the position angle at this moment, and a forehand, backhand or center is formed randomly depending on the position angle of the bounce plate 1, completing the "opponent". The "opponent" completes an unknown serve and return based on his / her own observation and judgment, i.e., staring at the ball, and with his / her right hand racket hits the ball discharged onto the opponent's table 22 with his / her backhand, forehand or center.

[0048] Training method 3: Example 4 uses an optimized device based on Example 1 (without a left-right continuous position angle swing mechanism, ground support platform 11, hereinafter referred to as the landing type manual device) as an example of a long-handed ball. The inclination (angle θ) of the plate surface of the bounce plate 1 of the landing type manual device is manually adjusted to an appropriate angle. Next, the landing type manual device is manually placed at positions 8, 12 or 16 on the floor of the opponent's side, and the plate surface of the bounce plate 1 is manually swung to the right at an appropriate angle (corresponding to the swing angle P). The player stands alone at an appropriate position on the hitting side of the opponent's table 20, holds a ball in his left hand, throws the ball at the bounce plate 1, and the ball is shot to the forehand side by the bounce plate 1. The "opponent" completes the serve and return of the opponent's forehand long ball. The "opponent" holds a racket in his right hand and hits the shot ball with a forehand push block or a forehand pull against the opponent's forehand long ball. The "opponent" completes the serve and return of the forehand long ball to the opponent's side, and the "opponent" holds the racket in his right hand and hits the ball into the opponent's table with a forehand push block or forehand pull, or changes the position angle of the surface of the rebound board 1 (corresponding to the angle of swing P) to the left, at which point the direction of the bounce changes, but he can move his body to form a backhand stroke. He can move his body to form a backhand shot and pull it.

[0049] Training method 4: Example 4 is an optimized device based on Example 2 (left and right continuous position angle swing mechanism 6, ground support frame 11, hereinafter referred to as the landing type electric device), which is similar to training method 2, but in this training method, the rebound plate 1 is supported on the ground, and the "opponent" randomly emits and hits back various long balls.

[0050] Training method 5: You will practice serving with a ball collecting net and hitting the ball back with your forehand after serving. Two table-type devices (table-type manual devices or table-type electric devices) are placed at the forehand ball and backhand ball positions (starting table surface space in the middle), and three balls are held in the left hand. First, one ball is thrown to train the player's serve, and the first ball is collected by the ball collecting net. Then, the second ball is hit from the left hand, bounced and hit the bounce board 1, the ball is bounced back to the forehand position, and the player continues to hit the forehand, then the third ball is hit and bounced and hit the backhand position of the bounce board 1, the ball is bounced back to the backhand position, and the player continues to hit the backhand, completing the simultaneous training of serve, forehand and backhand in sequence.

[0058] Buying a decent serving device is dozens of times more expensive than a utility model. Ball failure sometimes occurs (affects the mood of practice and may cause people to give up). It is not portable and takes up a lot of space. It is not easy to hire a one-on-one table tennis coach. The most commonly used desktop device in this utility model has a volume of 200*150*38mm (smaller than half the size of an A4 sheet of paper) and weighs 600 grams.

One of the core features is that the user can complete various changes of serves and counterattacks other than the spin ball, net touch, and edge ball made by the other player on the table tennis table of the user's side by himself. The "serve, counterattack" and the hit of the user are very close to the daily table tennis state, so the user can easily get the feeling of the ball. The second core feature is that it is inexpensive and not limited by the court. The user manually places this utility model at different positions on the table tennis table or the ground of the table tennis table, throws the ball to the ball and counterattack board 1 with the left hand, and swings the racket normally with the right hand to hit the ball, which is an action that both can complete to complete daily table tennis exercise by one person. By combining the ball collecting net, the messy scattering of multiple balls can be eliminated, and one person can practice improving continuous table tennis skills.

This utility model is inexpensive, small in volume, very easy to use, store and carry. In this utility model, a single person serves and hits the ball using a table-type device or a landing-type device outside the edge line of the player's side of the table, and collects each hit with a ball collection net (not shown in the figure) installed on the edge line 21 of the opponent's side. Throwing the ball at the ball-tossing board 1 with one hand is the same as throwing the ball to the best space position when serving, and the hand also makes the same movement as the toss.

[0062] This utility model allows you to practice serving and counterattacking on a table tennis table, which is close to the actual serving and counterattack. If you live at home or in an apartment complex (chair, bed, dining table, desk, vacant lot), you can achieve the same practice effect as in a ball court or training center, save time, transportation costs, and practice costs, and share the joy of table tennis with your family and friends.
