Description

Technical Field

[0001] This invention relates to the field of physical training technology, specifically to a physical training device with automatic feedback function. Background Technology

[0002] In today's society, people are paying more and more attention to health and physical fitness. The emergence of physical training devices with automatic feedback functions has a profound background demand. With the acceleration of the pace of life and the increase in work pressure, people's exercise volume has gradually decreased, physical fitness has generally declined, and various health problems have followed. Therefore, more and more people are beginning to pay attention to physical training, hoping to improve their health through scientific and effective exercise. However, traditional physical training methods have many limitations. They lack accurate data feedback. When doing bench press physical training, trainees often can only rely on subjective feelings to judge the training intensity and effect.

[0003] However, current bench press training equipment cannot perform reciprocating assisted training, leading to inconsistent training patterns during the bench press, which affects muscle growth and strength improvement. It also makes it difficult to train progressively, reducing training efficiency. Summary of the Invention

[0010] Preferably, a second bevel gear is provided on the outer wall of the first bevel gear, a lead screw is fixedly connected to the outer wall of the second bevel gear, a frame is rotatably connected to the outer wall of the lead screw, the upper surface of the frame is fixedly connected to the inner wall of the support frame, a movable block is threadedly connected to the outer wall of the lead screw, the outer wall of the movable block is slidably connected to the inner wall of the frame, and the lower surface of the movable block is fixedly connected to the upper surface of the support plate.

[0011] Preferably, the outer wall of the bench press bar is slidably connected to a handle, the lower outer walls of both ends of the handle are fixedly connected to blocks, a pressure sensor box is provided on the lower middle side of the handle, and a movable plate is slidably connected to the inner wall of the block.

[0012] Preferably, a third spring is fixedly connected to the lower surface of the movable plate, and the bottom end of the third spring is fixedly connected to the bottom end of the inner wall of the stop block.

[0013] Preferably, a fixed post is fixedly connected to the upper surface of the movable plate, and an inclined block is fixedly connected to the top of the fixed post. The outer wall of the inclined block is slidably connected to the inner wall of the handle.

[0014] Preferably, the lower side of the bench press bar has a slot, and the outer wall of the inclined block is set on the inner wall of the slot.

[0015] Working principle: When this device is needed, the specified bench press weight is controlled by rotating the counterweight plate at both ends of the bench press bar. The weight of the counterweight plate causes the bench press bar to press down, which in turn applies pressure through the support plate and sliding plate. The pressure is then transmitted through a first spring to a pressure sensor connected to the first spring, displaying the weight on the monitor. Both ends of the connecting box have displays on their outer walls, allowing users to adjust the initial weight, add counterweight plate, and then adjust the pressure at both ends to prevent injury. Afterward, lie on the mat on the support frame, grip the handles on both sides of the bench press bar, set the number of repetitions and speed, and then turn on the motor. The motor's output drives the eccentric wheel to rotate, which in turn drives the transmission plate to rotate around the outer wall of the support plate. The rotation point reciprocates, causing the transmission plate to move up and down via the connecting rod, which in turn moves the connecting boxes on the inner walls of the positioning frames at both ends in a regular up-and-down motion via the U-shaped frame. The support column assists in the up-and-down movement of the bench press bar, allowing the trainee to perform regular reciprocating bench presses. This ensures the muscles are in a state of dynamic tension, effectively stimulating muscle fibers, promoting muscle growth and improving physical fitness, while also ensuring safety during training. The pressure sensor on the palm of the grip records heart rate data, providing feedback on the training effect of different repetition counts and speeds. When adjusting the reciprocating distance of the bench press bar, rotating the handle causes the sliding column to rotate, which in turn moves the limiter... The positioning plate rotates within the circular cavity. When the limiting plate rotates into the groove of the support frame, the second spring rebounds through the fixing box, pushing the pressure plate inward. This disengages the limiting plate from the inner wall of the circular cavity until the first and second bevel gears mesh. Rotating the handle again then drives the first bevel gear via the sliding column. The first bevel gear, in turn, drives the lead screw to rotate inside the frame via the second bevel gear. The lead screw, through a threaded connection, drives the moving block to slide left and right within the frame. This allows the support plate to move the positioning block along the inner wall of the transmission plate, adjusting the rotational position of the transmission plate and thus the reciprocating distance of the bench press bar. This allows for precise stimulation of different muscle groups and adaptation to varying muscle groups. The desired effect during training is achieved by rotating the grips while holding them. This causes the incline blocks to rotate synchronously. When the incline blocks contact the incline surface of the bench press bar, they disengage from the inner wall of the slot until they are fully pressed against the inner wall of the grips. The grips at both ends can then be slid against the outer wall of the bench press bar to adjust for a comfortable grip position. Rotating the grips again causes the third spring to rebound through a stop block when the incline blocks slide into the slot, pushing the movable plate upwards. This, in turn, causes the incline blocks to slide into the inner wall of the slot via a fixed post, thus fixing the position of the grips at both ends. This achieves a fit to different body proportions and meets different training goals. Furthermore, the flexibility and versatility of the device can be further improved by adjusting the reciprocating distance.

[0016] This invention provides a physical training device with automatic feedback function. It has the following beneficial effects:

[0017] 1. This invention uses a motor to drive an eccentric wheel to rotate. The eccentric wheel causes the transmission plate to rotate back and forth around the outer wall of the support plate. The transmission plate drives the support block to move up and down through the connecting rod, which in turn causes the U-shaped frame to move the connecting box up and down in a regular manner. By observing the weight displayed on the monitor gradually decreasing the weight after the weight is increased, the invention achieves progressive training, improving training efficiency and safety.

[0018] 2. This invention uses a rotating handle to drive a sliding column, which in turn causes a limiting plate to rotate within the circular cavity. When the limiting plate rotates to the groove of the support frame, the second spring rebounds and pushes the pressure plate, causing the limiting plate to disengage from the inner wall of the circular cavity. The first and second bevel gears then mesh. Rotating the handle again causes the second bevel gear to drive the lead screw to rotate, moving the moving block and thus adjusting the rotation position of the transmission plate and the reciprocating distance of the bench press bar. This achieves precise stimulation of different muscle groups while adapting to the needs of different training stages.

[0019] 3. This invention rotates the handle to drive the inclined block to rotate. When the inclined block contacts the inclined surface of the bench press bar, it is squeezed against the inner wall of the handle. Then, the two ends of the handle are slid on the outer wall of the bench press bar to adjust the position. After that, the handle is rotated again. When the inclined block slides to the slot position, the spring rebounds and pushes the movable plate, which drives the inclined block to slide into the slot to fix the handle position. This achieves the effect of fitting different body proportions and training needs.

[0020] 4. This invention can change the angle of force and the degree of stretching of the muscles by adjusting the reciprocating distance of the bench press bar, thereby bringing new stimulation to the muscles. At the same time, it can adapt to different training goals of different trainees and, in combination with the position of the handle, help different trainees feel the force of the pectoralis major muscle and achieve better training results, thereby improving the applicability and flexibility of the device.

[0032] Specifically, the base plate 1 provides fixed support for the support frame 2, and the support frame 2 supports the position of the seat cushion to ensure the comfort of the trainee. At the same time, the support frame 2 provides fixed support for the motor 3 to ensure its stability during operation. The motor 3 can adjust its speed. When the motor 3 is turned on, its output end can drive the eccentric wheel 4 to rotate on the inner wall of the support frame 2. The eccentric wheel 4 can support the rotation position of one end of the transmission plate 5. In turn, the transmission plate 5 can drive the positioning block 38 to reciprocate on the outer wall of the support plate 6. The other end of the transmission plate 5 can support the rotation position of the connecting rod 7. The support block 8 can be moved up and down by pushing and pulling the connecting rod 7.

The support frame 2 provides fixed support for the positioning frame 11.

[0033] The sensing component includes a slide plate 12, the outer wall of which is slidably connected to the inner wall of the connecting box 10. A first spring 13 is fixedly connected to the lower surface of the slide plate 12. The bottom end of the first spring 13 is fixedly connected to the bottom inner wall of the connecting box 10. A weight sensor is provided at the connection between the first spring 13 and the bottom of the connecting box 10. A display 16 is provided on the outer wall of the connecting box 10.

[0034] Specifically, the connecting box 10 can support the sliding position of the slide plate 12, and at the same time, the connecting box 10 has a fixed support function for the first spring 13. The first spring 13 can be squeezed by the connecting box 10, so that the weight data can be recorded by the weight sensor and fed back in real time by the display 16.

[0035] A support column 14 is fixedly connected to the upper surface of the slide plate 12. The outer wall of the support column 14 is slidably connected to the inner wall of the connecting box 10.

The support column 14 provides fixed support for the bench press bar 15, ensuring the stability of the bench press bar 15. The bench press bar 15 can detect the initial weight of the weight sensor through the support column 14. The counterweight plate 25 can be installed at both ends of the bench press bar 15 through threads, and the weight at both ends is fed back through the display 16 to better meet the training needs of the trainee. When performing reciprocating movements, the trainee can try to make the weight displayed on the display 16 gradually smaller than the weight after the increase. Through assisted reciprocating training, a gradual training effect can be achieved, improving the training effect.

[0037] A fixed box 17 is fixedly connected to the outer wall of the support frame 2. A sliding column 18 is slidably connected inside the fixed box 17.

[0038] Specifically, the support frame 2 provides fixed support for the fixed box 17, and the fixed box 17 can support the sliding position of the slide column 18. The slide column 18 provides fixed support for the rotating handle 19. At the same time, when the rotating handle 19 is rotated, the slide column 18 can be driven to rotate, thereby driving the first bevel gear 20 to rotate synchronously.

[0039] A pressure plate 21 is fixedly connected to the outer wall of the sliding column 18. The outer wall of the pressure plate 21 is slidably connected to the inner wall of the fixed box 17.

[0040] Specifically, the sliding column 18 provides fixed support for the pressure plate 21. When the sliding column 18 is rotated, it can simultaneously drive the pressure plate 21 to rotate. The circular cavity 24 provides a limiting function for the limiting plate 23. When the limiting plate 23 rotates to the groove of the support frame 2, the second spring 22 rebounds through the fixing box 17. The resulting reverse force can push the pressure plate 21 to slide inward, thereby driving the first bevel gear 20 to slide inward.

[0041] The outer wall of the first bevel gear 20 is provided with a second bevel gear 34. The outer wall of the second bevel gear 34 is fixedly connected with a lead screw 35.

The lower surface of the moving block 36 is fixedly connected to the upper surface of the support plate 6.

[0042] Specifically, when the first bevel gear 20 slides inward and meshes with the second bevel gear 34, it rotates. At this time, the first bevel gear 20 can drive the second bevel gear 34 to rotate through the meshing connection. The second bevel gear 34 has a fixed support function for the lead screw 35, which can then drive the lead screw 35 to rotate. Through the threaded connection, the moving block 36 can be driven to slide left and right on the inner wall of the frame 37. The moving block 36 has a fixed support function for the support plate 6. The position of the transmission plate 5 lever rotation can be changed through the positioning block 38, thereby changing the reciprocating distance of the transmission plate 5, adjusting the reciprocating amplitude of the horizontal press rod 15, and improving the flexibility of the device.

A press sensor box 33 is provided on the lower middle side of the handle 26, and a movable plate 28 is slidably connected to the inner wall of the stop block 27.

[0044] Specifically, the bench press bar 15 can support the rotational position of the handle 26, while the handle 26 can prevent the trainee from dropping their hands during training. The handle 26 also provides fixed support for the stop block 27. The pressure sensor box 33 is located in the palm position when the handle 26 is held, so as to better collect the heart rate during training and transmit it to the display 16 for display. The stop block 27 can support the sliding position of the movable plate 28.

[0045] A third spring 29 is fixedly connected to the lower surface of the movable plate 28, and the bottom end of the third spring 29 is fixedly connected to the bottom end of the inner wall of the stop block 27.

The outer wall of the wedge block 31 is slidably connected to the inner wall of the handle 26. A slot 32 is opened inside the lower side of the bench press bar 15, and the outer wall of the wedge block 31 is set in the inner wall of the slot 32.

[0048] Specifically, the movable plate 28 provides fixed support for the fixed post 30, and the fixed post 30 can fix the position of the inclined block 31. Both sides of the inclined block 31 are inclined surfaces. When rotating the handle 26, the inclined block 31 can be squeezed and compressed to the inner wall of the handle 26 by the bench press bar 15. After rotating back to its original position, the rebound of the third spring 29 can push the inclined block 31 to slide to the inner wall of the slot 32, which can fix the position of the handle 26 on the bench press bar 15 and meet the needs of different trainees.
