[0002] Balance strength training is an important physical fitness training, which aims to improve the body's balance and stability, while strengthening the core muscle groups and other related muscles. In track and field, gymnastics, ball games and other events, good balance can help athletes control their bodies more effectively and improve the accuracy and efficiency of their movements. Therefore, athletes need to perform balance training regularly. Balance training is divided into static balance training and dynamic balance training. Static balance training refers to maintaining balance in a static state, such as the balance state when standing on one leg, and dynamic balance training refers to controlling the body to maintain balance during movement.

[0003] Currently, athletes often use balance beams, balance boards, balance balls, etc. for balance training. They can stand on one foot on the balance beam, balance board or balance ball and maintain body balance for as long as possible to perform static balance training. They can also maintain body balance while jumping, turning, etc. on the balance beam, balance board or balance ball to perform dynamic balance training.

[0004] However, due to the external force interference caused by many uncertain factors in actual competitions, such as uneven ground, opponent's movements, etc., the balance training using balance beams, balance boards, balance balls, etc. has limitations. It is difficult to simulate the external force interference in actual competitions, which reduces the effect of balance training. Summary of the invention

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the present invention provides a balance strength training device, including a training platform 1, two mounting plates 2, a support rod 9, a plurality of guide rods 12, a first moving mechanism and a second moving mechanism. The two mounting plates 2 are relatively vertically arranged on the training platform 1, and the lower part of each mounting plate 2 is fixedly connected to the training platform 1. At least one push block 7 is respectively arranged on the opposite surfaces of the two mounting plates 2. The interior of the training platform 1 is hollow, and a through groove 3 is opened at the position of the training platform 1 located between the two mounting plates 2. The through groove 3 is arranged along the length direction of the two mounting plates 2, and a training plate 4 is arranged in the through groove 3. The training board 4 is arranged along the length direction of the through slot 3, the support rod 9 is vertically arranged at the lower part of the training board 4, the upper end of the support rod 9 is movably connected to the training board 4, and the upper end of the support rod 9 is located at the lower center position of the training board 4, which is convenient for the training board 4 to swing around the upper end of the support rod 9. The lower end of the support rod 9 is fixed, and the support rod 9 provides a point of support for the training board 4. A plurality of guide rods 12 are vertically arranged in two rows below the training board 4, and the two rows of guide rods 12 are close to both sides of the training board 4, that is, the two rows of guide rods 12 are located on both sides of the support rod 9, and are not in the same straight line with the support rod 9. There is a gap between the upper end of each guide rod 12 and the training board 4, which is convenient for the training board 4 to swing up and down in an unstable state and the downward swinging distance is limited, so as to avoid the athlete standing on the training board 4 and completely stepping on the air and causing the athlete to fall. The first moving mechanism has a first moving end, which is connected to the lower ends of multiple guide rods 12. The first moving mechanism is used to drive each guide rod 12 to move up and down in turn, and each guide rod 12 lifts the training board 4, and cooperates with the support rod 9 for two-point support so that the training board 4 forms an unstable inclined plane, thereby driving the training board 4 to continuously swing up and down to form an unstable inclined plane and the balance point of the inclined plane constantly changes, simulating the athlete's body losing balance when passing through an uneven ground. The second moving mechanism has a second moving end, which is connected to the two push blocks 7. The second moving mechanism is used to drive the two push blocks 7 to move up and down, simulating the opponent's action, thereby providing external force interference for the athlete's balance training through the uneven ground and the opponent's action, making the balance training closer to the actual competition, avoiding the limitations of balance training using balance beams, balance boards, balance balls, etc., and improving the effect of balance training.

[0040] like Figure 3 As shown, a ball groove 10 is opened at the lower part of the training board 4 near the support rod 9, and a connecting ball 11 is arranged in the ball groove 10. The connecting ball 11 can rotate freely in the ball groove 10, and the lower part of the connecting ball 11 is connected to the upper end of the support rod 9, so that the edge of the training board 4 can swing up and down at different positions.

[0041] like Figure 1 As shown, stairs 5 are respectively provided at both ends of the training platform 1 , and the two stairs 5 facilitate athletes to get on and off the training platform 1 .

[0042] like Figure 2, Figure 3 , Figure 4 , Figure 5 As shown, the first moving mechanism includes a support plate 6, a moving block 15, two trapezoidal blocks 16 and a plurality of first rollers 14. The support plate 6 is horizontally fixedly arranged in the training platform 1 and is located at the lower end of the support rod 9. The lower end of the support rod 9 is fixedly connected to the support plate 6. The lower end of each guide rod 12 passes through the support plate 6 and is slidably connected to the support plate 6, so that each guide rod 12 can move up and down. A retaining ring 46 is fixedly sleeved at the position where each guide rod 12 is located at the upper part of the support plate 6. The lower part of the retaining ring 46 contacts the support plate 6 to prevent the guide rod 12 from moving upward. The downward movement completely passes through the support plate 6, so that the farthest distance between the upper end of each guide rod 12 and the training board 4 remains unchanged, and the farthest distance is the distance between the upper end of each guide rod 12 and the horizontal training board 4. The moving block 15 is arranged below the support plate 6, and the lower part of the moving block 15 is in contact with the inner bottom of the training platform 1 and is slidably connected, so that the moving block 15 slides along the inner bottom of the training platform 1. The moving block 15 is connected to the inner wall of the training platform 1 through a horizontal moving component, and the horizontal moving component is used to drive the moving block 15 along the inner bottom of the training platform 1. The two trapezoidal blocks 16 are arranged on the upper part of the moving block 15 and are respectively located close to the two rows of guide rods 12. The lower bottom surface of each trapezoidal block 16 is connected to the upper part of the moving block 15, so that the moving block 15 can move and drive the two trapezoidal blocks 16 to move. During the movement of the two trapezoidal blocks 16, they can contact the two rows of guide rods 12 in turn. The two trapezoidal blocks 16 are staggered front and back along the length direction of the training board 4, so that the two trapezoidal blocks 16 contact the two rows of guide rods 12 in turn. The multiple first rollers 14 are connected to the multiple guide rods 1 2 correspond one to one, each first roller 14 is arranged at the lower end of the corresponding guide rod 12, wherein the two opposite first rollers 14 are in contact with the upper part of the moving block 15, so that during the horizontal movement of the moving block 15, the two first rollers 14 can move relative to the moving block 15 on the moving block 15, and move successively to the upper part of the two trapezoidal blocks 16, driving the multiple guide rods 12 to move up and down in sequence, and at the same time, when each first roller 14 moves on the upper bottom surface of the corresponding trapezoidal block 16, it can provide a certain time for the athlete to find the balance point.

[0043] like Figure 2 , Figure 4 As shown, fixing rods 8 are vertically arranged between the upper part of the support plate 6 near the four corners and the top of the training platform 1, and the two ends of the fixing rods 8 are fixedly connected to the support plate 6 and the top of the training platform 1, respectively, so as to facilitate fixing the support plate 6 by means of the four fixing rods 8.

[0044] like Figure 2 As shown, a guide hole 45 is formed through the support plate 6 near each guide rod 12 , and each guide rod 12 passes through the corresponding guide hole 45 . Each guide rod 12 can slide freely up and down in the corresponding guide hole 45 .

[0045] like Figure 4 , Figure 5 As shown, the horizontal moving assembly includes a screw rod 26 and a motor 27. The screw rod 26 is horizontally arranged below the support plate 6 and is relatively parallel to the training plate 4. The two ends of the screw rod 26 are respectively rotatably connected to the inner wall of the training platform 1. The screw rod 26 passes through the moving block 15 and is threadedly connected to the moving block 15. The motor 27 is arranged on the side of the training platform 1 and is located close to one end of the screw rod 26. The output end of the motor 27 is connected to the end of the screw rod 26, that is, the end of the screw rod 26 close to the motor 27 passes through the side of the training platform 1 and is connected to the output end of the motor 27. A driving cavity is opened in the step 5 close to the motor 27. The motor 27 is fixedly arranged in the driving cavity. The motor 27 is started, and the motor 27 drives the screw rod 26 to rotate slowly. The screw rod 26 drives the moving block 15 to move slowly along the length direction of the training plate 4. The moving block 15 drives the two trapezoidal blocks 16 to move slowly along the length direction of the training plate 4, so that each first roller 14 of the two columns passes through the corresponding trapezoidal block 16 in sequence.

[0046] like Figure 3 , Figure 4 As shown, first elastic members 22 are vertically arranged at the four corners of the lower part of the training board 4, and the two ends of the first elastic members 22 are respectively connected to the training board 4 and the support plate 6. The four first elastic members 22 facilitate the reset of the training board 4 after swinging. At the same time, different positions on both sides of the training board 4 can also form different inclined surfaces after swinging up and down, so that the balance point of the training board 4 can be continuously and rapidly changed, thereby improving the effect of simulating uneven ground. Each guide rod 12 is located between the support plate 6 and the first roller 14, and a second elastic member 23 is sleeved thereon, so that each guide rod 12 can be reset after moving upward, so that the balance point adjustment of the training board 4 can be completed quickly.

[0047] like Figure 3 , Figure 6As shown, a moving groove 47 is provided at the upper part of the moving block 15 near the two trapezoidal blocks 16, each moving groove 47 is arranged along the length direction of the training board 4, and a connecting rod 34 is vertically arranged in each moving groove 47, and the upper end of the connecting rod 34 is fixedly connected to the corresponding trapezoidal block 16, and a relative moving component is arranged in the moving block 15, and the relative moving component is connected to the two connecting rods 34, and the relative moving component is used to drive the two trapezoidal blocks 16 to move relative to each other in the length direction of the training board 4 during the movement of the moving block 15, so that the distance between the two trapezoidal blocks 16 in the length direction of the training board 4 is The distance gradually decreases until they are in the same straight line in the width direction of the training board 4, and then the distance gradually increases, so that the time interval for the two guide rods 12 opposite to each other in the width direction of the training board 4 to move upwards successively first gradually decreases until it is zero, and then gradually increases, so that the balance point on the training board 4 is gradually moved away from the center line in the process of alternating movement on both sides of the center line in the length direction of the training board 4 until it moves to the center line, and then gradually increases, thereby making the position change of the balance point on the training board 4 more diverse, making the simulation of uneven road surface more diverse, and further improving the effect of balance training.

[0048] like Figure 6 , Figure 7 As shown, the moving assembly includes a mounting cavity 33, two first racks 35, a transmission shaft 40 and a first gear 35.

The first gear 35 is sleeved on the transmission shaft 40, and the first gear 35 is respectively meshed with the two first racks 35. The transmission shaft 40 rotates intermittently, driving the first gear 35 to rotate intermittently. The first gear 35 drives the two first racks 35 to move intermittently. The two first racks 35 drive the two trapezoidal blocks 16 to move relative to each other through the two connecting rods 34, so that the distance between the two trapezoidal blocks 16 gradually decreases and then gradually increases.

[0049] like Figure 6 , Figure 7As shown, a limit rod 38 is horizontally arranged near each first rack 35 in the installation cavity 33, and the limit rod 38 is relatively parallel to the corresponding movable groove 47. The two ends of the limit rod 38 are respectively fixedly connected to the inner wall of the installation cavity 33, and a limit hole 39 is penetrated through the position of each first rack 35 near the corresponding limit rod 38. The limit rod 38 passes through the limit hole 39 and is slidably connected to the limit hole 39, so that each first rack 35 slides along the corresponding limit rod 38. At the same time, the cross-sections of the limit rod 38 and the limit hole 39 are mutually matched quadrilateral structures, which prevents the first rack 35 from rotating around the limit rod 38, so that the horizontal movement of the first rack 35 is more stable.

The two ends of the fourth elastic member 25 are respectively connected to the push block 7 and the slider 18, so as to facilitate the first plunger cylinder 19 to reset after being extended. A second plunger cylinder 20 is vertically arranged on the upper part of each slider 18, and a liquid storage cavity is arranged in each slider 18, and the liquid storage cavity is respectively communicated with the first plunger cylinder 19 and the second plunger cylinder 20. Hydraulic oil is arranged in the liquid storage cavity, and the pressure in the first plunger cylinder 19 and the second plunger cylinder 20 is transmitted through the hydraulic oil. When each slider 18 moves upward, it drives the first plunger cylinder 19 and the second plunger cylinder 20 to move upward. The second plunger cylinder 20 moves upward, and the first plunger cylinder 19 drives the corresponding push block 7 to move upward. The upper end of the second plunger cylinder 20 contacts the upper end of the corresponding slide groove 17 and is compressed, and the pressure is transmitted to the first plunger cylinder 19, driving the first plunger cylinder 19 to extend. The extension of the first plunger cylinder 19 drives the push block 7 to move toward the training board 4. When each slider 18 moves downward, the first plunger cylinder 19 contracts under the elastic force of the fourth elastic member 25, driving the push block 7 to move away from the training board 4. The push block 7 is driven to move up and down while moving left and right, making the opponent's movements more diverse, further improving the effect of balance training.

[0055] like Figure 1 As shown, there are multiple push blocks 7 arranged on the side of each mounting plate 2, and multiple push blocks 7 form a group. Multiple push blocks 7 are evenly arranged along the length direction of the mounting plate 2, and two groups of push blocks 7 are staggered, simulating multiple opponents at different positions on both sides to interfere with the athlete with external force, further making the opponent's movements more diverse.

[0056] The number of cams 29 on each rotating shaft 28 corresponds to that of the push blocks 7. The angles between the farthest ends of the multiple cams 29 and the horizontal plane are different, so that the heights of the multiple push blocks 7 after moving upward are different, further making the simulated opponent's movements more diverse. At the same time, each first plunger cylinder 19 is coordinated with the corresponding second plunger cylinder 20, so that the distance that each push block 7 moves left and right is different, further making the opponent's movements more diverse.

[0057] Working principle: During training, the motor 27 is started, and the motor 27 drives the lead screw 26 to rotate slowly. The lead screw 26 drives the moving block 15 to move slowly along the guide rail 43. The moving block 15 drives the two trapezoidal blocks 16 to move slowly along the length direction of the training board 4, so that each first roller 14 of the two columns passes through the corresponding trapezoidal block 16 in turn. In the initial stage, the moving block 15 is at the leftmost side. When the two first rollers 14 on the leftmost side move to the moving block 15, one of them passes through the moving block 15 first, and drives the corresponding guide rod 12 to move upward. The guide rod 12 drives one side of the training board 4 to swing upward to form an inclined plane, and after passing the moving block 15, drives the training board 4 to swing downward, and the other guide rod 12 drives the other side of the training board 4 to swing up and down again, and so on and so forth, continuously driving the two sides of the training board 4 to swing up and down at different positions, so that the training board 4 continuously forms an unstable inclined plane and the balance point of the inclined plane continuously changes, simulating the uneven ground.

[0058] When the moving block 15 moves slowly along the guide rail 43, the transmission shaft 40 drives the second gear 31 to move slowly in the installation groove 44. When the second gear 31 meshes with each second rack 41 in turn, it drives the second gear 31 to rotate intermittently, and the second gear 31 drives the transmission shaft 40 to rotate intermittently. The transmission shaft 40 drives the first gear 35 to rotate intermittently, and the first gear 35 drives the two first racks 35 to move intermittently. The two first racks 35 drive the two trapezoidal blocks 16 to move relative to each other through the two connecting rods 34, so that the distance between the two trapezoidal blocks 16 in the length direction of the training board 4 gradually decreases until they are in the same straight line in the width direction of the training board 4, and then the distance gradually increases, so that the time interval between the two guide rods 12 opposite to each other in the width direction of the training board 4 first gradually decreases until it is zero, and then gradually increases, so that the balance point on the training board 4 is gradually reduced in the process of alternatingly moving on both sides of the midline in the length direction of the training board 4. The distance from the midline gradually decreases until it moves to the midline, and then gradually increases, thereby making the position change of the balance point on the training board 4 more diverse, making the simulation of uneven road surface more diverse.

[0059] At the same time, when the screw rod 26 rotates slowly, it drives the third gear 36 to rotate, and the third gear 36 drives the two fourth gears 37 to rotate through the tooth chain 32. The two fourth gears 37 drive the two rotating shafts 28 to rotate. Each rotating shaft 28 drives the multiple cams 29 thereon to rotate. Each cam 29 drives the corresponding push rod 21 to move up and down. The push rod 21 slider 18 drives the push block 7 to move up and down, simulating the opponent's actions.

[0060] When the slider 18 moves up and down, it drives the first plunger cylinder 19 and the second plunger cylinder 20 to move upward. The upper end of the second plunger cylinder 20 contacts the upper end of the corresponding slide groove 17 and is compressed, and the pressure is transmitted to the first plunger cylinder 19, driving the first plunger cylinder 19 to extend. The extension of the first plunger cylinder 19 drives the push block 7 to move toward the training board 4. When each slider 18 moves downward, the first plunger cylinder 19 contracts under the elastic force of the fourth elastic member 25, driving the push block 7 to move away from the training board 4. The push block 7 is driven to move up and down and left and right at the same time, making the simulated opponent's movements more diverse.
