[0019] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.

[0020] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] Please refer to Figures 1 to 6 The intelligent shot put training device of the present invention includes: a first vertical frame 100; a second vertical frame 200, which is opposite to the first vertical frame 100 and is spaced apart; at least one guide rail 300, the guide rail 300 is arranged at an angle, the first vertical frame 100 and the second vertical frame 200 respectively support the guide rail 300, a first photoelectric switch sensor 310 and a second photoelectric switch sensor 320 are spaced apart on the guide rail 300, and a force sensor 330 is fixedly connected to the vertically higher side of the guide rail 300; a throwing mechanism 400, which is connected to the guide rail 300 and moves along the guide rail 300, and the force sensor 330 is located at the end 350 of the guide rail 300; a display screen 500, and the first photoelectric switch sensor 310, the second photoelectric switch sensor 320 and the force sensor 330 are respectively electrically connected to the display screen 500.

[0022] In an embodiment of the present invention, the first vertical frame 100 and the second vertical frame 200 are respectively placed on the ground, and the guide rail 300 is arranged at an angle. The first vertical frame 100 and the second vertical frame 200 respectively support the guide rail 300, thereby improving the stability of the guide rail 300, that is, improving the stability of the intelligent shot put trainer.

[0023] The first vertical frame 100 and the second vertical frame 200 can be arranged in a vertical direction to further improve stability. Of course, a frame or base can be fixed at the bottom of the first vertical frame 100 and the second vertical frame 200 to prevent the first vertical frame 100 and the second vertical frame 200 from tilting.

[0024] The guide rail 300 is tilted, and the throwing mechanism 400 is connected to and moves along the guide rail 300. A user can stand on the lower side of the guide rail 300 and push the throwing mechanism 400 along the guide rail 300 from the initial end 340 to the final end 350 to practice shot put throwing. After the throwing mechanism 400 reaches the final end 350, it returns to the initial end 340 under the action of its own gravity, allowing the user to continue throwing, thereby improving the efficiency of throwing training.

[0025] The number of the guide rail 300 can be one or more, and one guide rail 300 corresponds to one throwing mechanism 400. When multiple guide rails 300 and multiple throwing mechanisms 400 are provided, multiple users can perform throwing training synchronously. Figures 1 to 3 As shown, two guide rails 300 and two throwing mechanisms 400 are provided. The two guide rails 300 can be tilted in opposite directions. When the throwing mechanisms 400 are located at the initial end 340 of the guide rails 300, one throwing mechanism 400 is located on the side of the first vertical frame 100, and the other throwing mechanism 400 is located on the side of the second vertical frame 200. This makes the overall weight distribution of the intelligent shot put training device even, further improving the stability of the intelligent shot put training device.

[0026] A first photoelectric switch sensor 310 and a second photoelectric switch sensor 320 are spaced apart on the guide rail 300 , and the first photoelectric switch sensor 310 and the second photoelectric switch sensor 320 are used to obtain the user's throwing speed information and throwing number information.

[0027] When the user is performing shot put training and pushes the throwing mechanism 400 to move along the guide rail 300, if the first photoelectric switch sensor 310 and the second photoelectric switch sensor 320 are triggered at the same time, it is counted as a valid throw and the number of throws is calculated. If only one of the first photoelectric switch sensor 310 and the second photoelectric switch sensor 320 is triggered, it is not counted as a valid throw and the number of throws is not calculated. The distance between the first photoelectric switch sensor 310 and the second photoelectric switch sensor 320 is divided by the time difference between the triggering of the first photoelectric switch sensor 310 and the second photoelectric switch sensor 320 to obtain the movement speed of the throwing mechanism 400, that is, to obtain the throwing speed information. The first photoelectric switch sensor 310 and the second photoelectric switch sensor 320 are electrically connected to the display screen 500 respectively, and the number of throws information and the throwing speed information can be displayed on the display screen 500.

[0028] A force sensor 330 is fixedly connected to the vertically higher side of the guide rail 300. Specifically, the force sensor 330 is located at the end 350 of the guide rail 300. When the throwing mechanism 400 is pushed along the guide rail 300 and reaches the end 350 of the guide rail 300, it collides with the force sensor 330, which then acquires the throwing force information. Of course, if the throwing mechanism 400 does not trigger the force sensor 330, the throwing force information is zero. The force sensor 330 is electrically connected to the display screen 500, and the throwing force information can be displayed on the display screen 500.

[0029] The first photoelectric switch sensor 310 and the second photoelectric switch sensor 320 are used to obtain information about the number of throws and the throwing speed. The force sensor 330 is used to obtain information about the throwing force. By displaying the throwing force, number of throws, and throwing speed information on the display screen 500, the user can easily view the results of their shot put training. Training plans can be tailored to the user's individual needs, and training progress and results can be monitored, making training more intelligent.

[0030] Please refer to Figure 3 and 4 Furthermore, the throwing mechanism 400 includes a sphere 410, a load rod 420, a moving part 430 and a plurality of rollers 440. The sphere 410 is detachably fixedly connected to the moving part 430, the load rod 420 is fixedly connected to the moving part 430, the load rod 420 is used to connect the load, and the plurality of rollers 440 are respectively rotatably connected to the moving part 430. The plurality of rollers 440 roll on the guide rail 300 respectively. The rollers 440 are respectively distributed on both sides of the guide rail 300, and the plurality of rollers 440 are distributed on at least one side of the guide rail 300.

[0031] In an embodiment of the present invention, a moving member 430 is rotatably connected to a plurality of rollers 440, which respectively roll on the guide rail 300. When a user pushes the throwing mechanism 400 to move, the moving member 430 moves along the guide rail 300, and the rollers 440 roll, reducing the friction between the moving member 430 and the guide rail 300, making the moving member 430 move more smoothly. The rollers 440 are respectively distributed on both sides of the guide rail 300, and the plurality of rollers 440 are distributed on at least one side of the guide rail 300, ensuring the reliability of the connection between the moving member 430 and the guide rail 300. Figure 4 As shown in FIG, two rollers 440 are distributed above the guide rail 300, and two rollers 440 are distributed below the guide rail 300.

[0032] The movable member 430 is connected to a sphere 410, which the user can grasp to propel the movable member 430. The sphere 410 simulates the shape of a shot put, making the intelligent shot put trainer more realistic and ensuring the effectiveness of shot put training. Of course, the sphere 410 and movable member 430 are detachably fixedly connected. If the sphere 410 becomes damaged, it can be replaced, reducing the maintenance cost of the intelligent shot put trainer.

[0033] The moving member 430 is connected to the load rod 420 , and loads of different gravities can be connected to the load rod 420 , thereby meeting different training needs of users and the training requirements of different users.

[0034] Furthermore, the load rod 420 is located on the top of the moving member 430 , and a plurality of load sheets are sleeved on the load rod 420 .

[0035] In an embodiment of the present invention, a load rod 420 is arranged on top of the movable member 430, and a plurality of load plates are sleeved on the load rod 420, so that the movable member 430 can support the load plates, thereby improving the stability of the throwing mechanism 400. The user can sleeve different numbers of load plates or load plates of different weights on the load rod 420 according to training needs to perform shot put throwing training. Of course, an anti-detachment clip can be provided on the load rod 420 to prevent the load plates from detaching from the load rod 420, thereby ensuring the safety of shot put throwing training. The load is in the form of a load plate, such as, but not limited to, a bell plate.

[0036] Furthermore, the sphere 410 is located on one side of the moving member 430 .

[0037] In the embodiment of the present invention, the ball 410 is located on one side of the moving member 430 , so that the user can grasp the ball 410 to push the throwing mechanism 400 to move.

[0038] Please refer to Figure 3 Furthermore, a pulley 110 and a buffer mechanism 600 are provided on the first vertical frame 100 or the second vertical frame 200 on the vertically higher side of the support guide rail 300. The buffer mechanism 600 is connected to the throwing mechanism 400 through a flexible connector 120. The flexible connector 120 bypasses the pulley 110. When the throwing mechanism 400 falls back to the initial end 340 of the guide rail 300, the buffer mechanism 600 pulls the throwing mechanism 400 through the flexible connector 120.

[0039] In the embodiment of the present invention, a first vertical frame 100 supporting the vertically higher side of the guide rail 300 is used as an example for detailed description. A buffer mechanism 600 and a pulley 110 are disposed on the first vertical frame 100. A flexible connector 120 passes around the pulley 110. One end of the flexible connector 120 is connected to the throwing mechanism 400, and the other end of the flexible connector 120 is connected to the buffer mechanism 600. When the throwing mechanism 400 is pushed to the end 350 and then returns from the end 350 to the starting end 340, the throwing mechanism 400 experiences a high speed and impact force due to its own gravity. At this time, the buffer mechanism 600 pulls the throwing mechanism 400 via the flexible connector 120, buffering the impact force of the throwing mechanism 400, preventing the throwing mechanism 400 from injuring the user and ensuring training safety for the user. The flexible connector 120 may be, but is not limited to, a steel wire rope, a connecting belt, or the like.

[0040] Please refer to Figure 3 and 6 Furthermore, the buffer mechanism 600 includes a double-headed cylinder 610 and a guide rod 620. The double-headed cylinder 610 includes a cylinder body 611 and a piston rod 612. The cylinder body 611 is fixedly connected to the first vertical frame 100 or the second vertical frame 200. One end of the piston rod 612 is connected to the flexible connector 120. The other end of the piston rod 612 is connected to the sliding plate 630. The guide rod 620 is fixedly connected to the first vertical frame 100 or the second vertical frame 200. The sliding plate 630 is slidably connected to the guide rod 620. The guide rod 620 is fixedly connected with a stop block 621. The guide rod 620 is sleeved with a first spring 622. The stop block 621 is located on the side of the sliding plate 630 facing the double-headed cylinder 610. The first spring 622 is located between the sliding plate 630 and the stop block 621.

[0041] In the embodiment of the present invention, the vertically higher side of the guide rail 300 supported by the first vertical frame 100 is used as an example for detailed description. The cylinder body 611 and the guide rod 620 are respectively fixedly connected to the first vertical frame 100. When the throwing mechanism 400 falls back to the initial end 340 of the guide rail 300, the throwing mechanism 400 pulls the piston rod 612 through the flexible connector 120, and the double-headed cylinder 610 provides resistance to the movement of the piston rod 612. Furthermore, the piston rod 612 drives the sliding plate 630 toward the cylinder body 611, compressing the first spring 622, which provides resistance to the movement of the sliding plate 630. The double-headed cylinder 610 and the first spring 622 provide a double cushioning effect when the throwing mechanism 400 falls back to the initial end 340 of the guide rail 300, preventing the throwing mechanism 400 from injuring the user and ensuring user training safety. Of course, the opening of the throttle valve of the double-headed cylinder 610 or the air pressure inside the double-headed cylinder 610 can be adjusted to adjust the resistance of the double-headed cylinder 610 to achieve buffering of the throwing mechanism 400 under different counterweights.

[0042] Please refer to Figures 3-5 Furthermore, the guide rail 300 is fixedly connected with a first stop mechanism 360 and a second stop mechanism 370 , the first stop mechanism 360 is located at the initial end 340 of the guide rail 300 , and the second stop mechanism 370 is located at the end 350 of the guide rail 300 .

[0043] In an embodiment of the present invention, a first stopper 360 is located at the initial end 340 of the guide rail 300. The first stopper 360 can stop the throwing mechanism 400 and prevent the throwing mechanism 400 from detaching from the guide rail 300 at the initial end 340. A second stopper 370 is located at the end 350 of the guide rail 300. The second stopper 370 can stop the throwing mechanism 400 and prevent the throwing mechanism 400 from detaching from the guide rail 300 at the end 350.

[0044] Please refer to Figures 3-5 Furthermore, the first stop mechanism 360 includes a first positioning rod 361, which is fixedly connected to the guide rail 300. The first positioning rod 361 is sequentially sleeved with a first stop piece 362, a second spring 363 and a first buffer block 364. The first buffer block 364 is located on the movement path of the throwing mechanism 400, and the second spring 363 is located on the side of the first buffer block 364 facing away from the throwing mechanism 400.

[0045] In an embodiment of the present invention, when the throwing mechanism 400 falls back to the initial end 340 of the guide rail 300, the throwing mechanism 400 contacts the first buffer block 364, which drives the first buffer block 364 toward the first stopper 362. The second spring 363 is compressed, thereby providing a buffer for the throwing mechanism 400. A first annular protrusion may be provided on the end of the first positioning rod 361 near the throwing mechanism 400 to prevent the first buffer block 364 from separating from the first positioning rod 361.

[0046] Please refer to Figures 3-5 Furthermore, the second stop mechanism 370 includes a second positioning rod 371, which is fixedly connected to the guide rail 300. The second positioning rod 371 is sequentially sleeved with a second stop piece 372, a third spring 373 and a second buffer block 374. The second buffer block 374 is located on the movement path of the throwing mechanism 400, and the third spring 373 is located on the side of the second buffer block 374 facing away from the throwing mechanism 400.

[0047] In an embodiment of the present invention, when the throwing mechanism 400 is pushed to the end 350 of the guide rail 300, the throwing mechanism 400 contacts the second buffer block 374, which drives the second buffer block 374 toward the second stopper 372. The third spring 373 is compressed, thereby providing a buffer for the throwing mechanism 400. A second annular protrusion may be provided on the end of the second positioning rod 371 near the throwing mechanism 400 to prevent the second buffer block 374 from separating from the second positioning rod 371.

[0048] Please refer to Figures 3-5 Furthermore, the second positioning rod 371 is fixedly connected to the support shell 375 , the force sensor 330 is located in the support shell 375 , and the second stop piece 372 is against the force sensor 330 .
