Description

Technical Field

[0001] This invention relates to the field of sports training technology, specifically to a multifunctional training device and method for sports activities. Background Technology

[0002] With the increasing awareness of fitness among the general public, sports training equipment is being used more and more widely in homes and professional training venues. Existing training equipment is relatively simple in terms of function, such as arm and leg trainers, abdominal muscle trainers, bench press racks, etc., which are designed independently for different muscle groups or training methods. If users need to conduct comprehensive upper and lower limb strength training, they often need to purchase multiple independent devices at the same time. This not only increases the purchase cost, but also occupies a lot of indoor space, which is especially inconvenient for users with limited living space.

[0003] In existing technologies, to overcome the problem of single-function training devices, some manufacturers have launched multi-functional integrated training devices. These devices can be adapted to different training programs by switching components or adjusting the structure. However, existing solutions generally suffer from complex structural designs and cumbersome mode-switching operations. When switching between different training states, users often need to perform multiple adjustments such as disassembly, repositioning, or tightening, which is time-consuming and disrupts the training rhythm. In addition, existing multi-functional integrated training devices are generally bulky and lack effective folding mechanisms, failing to meet the requirements for compact storage when not in use and thus failing to solve the problem of occupying indoor space.

[0004] For example, patent application number 202422832382.6, published on October 31, 2025, discloses a strength training device for sports training, including a base plate and a weightlifting bar. Two support rods are fixedly connected to the top of the base plate. Multiple fixed rings are slidably connected inside the two support rods. Two connecting plates are fixedly connected to the outside of the multiple fixed rings. Sliding rods are fixedly connected inside the multiple fixed rings. Springs are sleeved on the outside of the multiple sliding rods. A locking post is fixedly connected to the front side of the multiple connecting plates. A docking plate is slidably connected to the front side of the two support rods. Sliding grooves and locking slots are formed inside the two docking plates.

[0005] The above technical solution uses the lying board and support pad as foldable storage components, which are placed on the base plate. Two support rods are also installed on the base plate. The weightlifting bar and counterweight plate need to be fixed to the side of the support rods through support rings on the support rods. Therefore, the support rods need to have a certain degree of rigidity and stiffness to withstand the downward pressure of the weightlifting bar and counterweight plate. In order to meet the requirements of bench press, the length of the base plate needs to be greater than or equal to the length of the lying board, which will occupy a lot of indoor space. The base plate with a certain degree of rigidity and stiffness will also be heavy, which is not conducive to moving it to other areas when not in use. The base plate can only be used to place the lying board and perform upper limb exercises on the lying board, and cannot be used for other exercises, thus failing to facilitate multiple exercises. Summary of the Invention

[0006] This invention provides a multifunctional training device and method for sports, which can store some components without occupying too much indoor space, while meeting the purpose of multifunctional training and guiding the accuracy of training movements.

[0007] To achieve the above objectives, one aspect of the technical solution provided by the present invention is: a multifunctional training device for sports, comprising a first support frame, a training board, a hook assembly disposed on the first support frame, a second support frame, a hook assembly disposed on the second support frame, and a connecting assembly disposed between the first and second support frames. A mounting groove is provided at one end of the training board, and a display assembly is rotatably disposed within the mounting groove. First rotating shafts are respectively provided on both sides of the other end of the training board. One end of the first rotating shaft is fixedly connected to the training board, and the other end of the first rotating shaft is rotatably connected to the second support frame. The training board rotates around the second support frame and is accommodated between the first and second support frames. A rolling device is provided on the training board, and a pressure detection device is provided on the rolling device. The display assembly rotates to the top of the training board according to the pressure detected by the detection device.

[0008] The above configuration, through the installation slot and the display component inside the slot, allows the display component to be embedded inside the training board when not in use, preventing collisions with the display component by passing personnel and reducing the space occupied when the training board is placed flat. A pressure detection device on the training board detects pressure and controls the opening of the display screen, allowing users to easily perform exercises based on the actions displayed on the screen. Simultaneously, the first rotation axis allows the training board to rotate relative to the second support frame, enabling it to be placed horizontally on the ground when in use, or vertically placed within the first and second support frames when stored. This reduces the overall space occupied by the device when not in use and makes rotation easier, without requiring excessive physical exertion from the trainee. Furthermore, hook components on the first and second support frames allow for the insertion of a barbell for storage, while also providing counterweight to the training board when stored.

[0009] Furthermore, a baffle is provided on one side of the training board, and a first mounting hole is opened at each of the four corners of the baffle. A storage cavity is opened inside the training board, and the storage cavity is opened and closed by the baffle.

[0010] The above setup involves fixing a baffle to one side of the training board and setting first mounting holes at the four corners of the baffle. This allows the baffle to be detachably connected to the side wall of the training board by fasteners passing through the first mounting holes. This creates a closed space for the storage box inside the training board. When the accessories inside the storage box are not needed, the storage box can prevent the accessories from sliding out or being lost, thus reducing the occupancy rate of the indoor space.

[0011] Furthermore, the display component includes a display screen and a rotating part. A second rotating shaft is disposed through the interior of the rotating part. The second rotating shaft is rotatably connected to the top of the mounting slot. A driving device is disposed inside one end of the training board. One end of the second rotating shaft is connected to the driving device for transmission.

[0012] The above configuration, by setting up a display component and a second rotating shaft, enables the rotating part and display screen to rotate upward by driving the second rotating shaft. By setting up a driving component, on the one hand, the trainee does not need to manually apply force to flip it, and on the other hand, the driving device is set inside the training board to avoid being affected by sweat or dust during training, and the space occupied by the display component is reduced.

[0013] Furthermore, the pressure detection device includes a first pressure sensor. One or more first magnetic plates and first pressure sensors are respectively provided on both sides of the top of the training board. The first magnetic plates and first pressure sensors are embedded in the training board. A first sliding groove is provided between the first magnetic plates on both sides, and the first sliding groove extends recessed into the training board. A first pad and one or more second pads are also provided on the top of the training board. A second magnetic plate is provided on one side of both the first pad and the second pad, and a first pressure sensor is provided on the other side of the first pad.

[0014] The above configuration, by setting up the first magnetic plate, ensures that it does not bulge upwards and affect the trainee, thus maintaining the flatness of the training board surface. Simultaneously, the first magnetic plate provides positioning and guidance for the subsequent magnetic fixation of other components, reducing the time required for component installation or removal. The first pressure sensor allows for real-time detection of pressure data in the covered area, providing a data foundation for subsequent pressure data processing. The first sliding groove restricts its guiding direction, ensuring a flat, straight trajectory, allowing the trainee to focus on the target muscle group and preventing excessive leverage from other parts, resulting in better training effects. The second magnetic plate allows for attraction with the first magnetic plate on the training board, enabling quick installation and removal of both the first and second pads. The first pressure sensor transmits the pressure applied by the trainee to the first pad. The first and second pads provide flexible support for different areas of the training board according to usage needs, and also offer diverse support solutions for different training postures, improving the applicability of the device.

[0015] Furthermore, the pressure detection device includes a second pressure sensor, the rolling assembly includes a rotating wheel and a support plate, the rotating wheel is located at the bottom of the support plate, the second pressure sensor is located on the top surface of the support plate, and a handrail is fixedly installed at the front end of the support plate.

[0016] The above setup, by incorporating a rolling assembly, allows the rotating wheel to roll within the first sliding groove, reducing friction between the support plate and the training plate. This allows trainees to drive the rolling assembly along the first sliding groove with minimal pushing force. A second pressure sensor on the support plate collects pressure data from the trainee's elbow or forearm. This pressure data, combined with that from the first sensor, provides a basis for assessing the trainee's condition. Handrails provide a fixed grip point for the trainee, improving the device's stability during training.

[0017] Furthermore, connecting components are respectively provided between the top of the first support frame and the bottom of both sides of the second support frame. The connecting components include a sleeve and a connecting rod. One end of the sleeve is fixedly connected to the first support frame, and the other end of the sleeve is provided with a through hole. One end of the connecting rod is fixedly connected to the second support frame, and the other end of the connecting rod is a free end. The connecting rod is provided with one or more through holes. The first support frame and the second support frame are connected by fasteners passing through the through holes on the sleeve and the connecting rod in sequence.

[0018] The above configuration, by setting up a sleeve and a connecting rod, allows the connecting rod to enter the sleeve horizontally. By changing the depth of the connecting rod's insertion into the sleeve, the horizontal distance between the first and second support frames is changed. By setting through holes in the sleeve and the connecting rod, fasteners can be sequentially passed through the through holes at the end of the sleeve and the through holes on the connecting rod, thereby fixing the horizontal distance between the first and second support frames, preventing the connecting rod from slipping relative to the sleeve during training, and improving the stability of the device.

[0019] Furthermore, a second mounting hole and a third mounting hole are respectively provided on both sides of the training board. The second mounting hole is located at one end of the training board, and the third mounting hole is located in the middle of the training board. Mounting holes are provided at the bottom of the first support frame and the top of the second support frame. The horizontal distance between the third mounting hole and the first rotating shaft is equal to the horizontal distance between the bottom of the first support frame and the bottom of the second support frame.

[0020] The above configuration, by providing a second mounting hole, ensures that when the training board is placed vertically, the second mounting hole corresponds to the through hole at the top of the second support frame. Fasteners passing through the through hole and the second mounting hole in sequence secure the training board in its vertical position, preventing it from rotating and tipping over when not in use. By providing a third mounting hole and limiting the horizontal distance between the third mounting hole and the first rotating shaft, when the training board is placed horizontally, the third mounting hole corresponds to the through hole at the bottom of the first support frame. Fasteners passing through the mounting hole at the bottom of the first support frame and the third mounting hole in sequence secure the training board in its horizontal position. This configuration not only prevents displacement of the training board during training, improving the stability of the device, but also provides guidance during installation, reducing assembly time.

[0021] Furthermore, the first support frame and the second support frame are provided with second sliding grooves on the front and rear sides of the column respectively. The second sliding grooves extend along the length direction of the first support frame and the second support frame, and extend along the internal recess of the first support frame and the second support frame. Two or more positioning holes are provided through the interior of the second sliding groove. The first support frame and the second support frame are provided with third sliding grooves on the left and right sides of the columns respectively. The third sliding grooves extend along the length of the first support frame and the second support frame, and extend along the internal recesses of the first support frame and the second support frame.

[0022] The above configuration, by setting a second sliding groove and a positioning hole through the second sliding groove, provides a guide rail extending longitudinally along the column for external components. By moving the external components on the second sliding groove, it can adapt to the mounting requirements of different heights. At the same time, the positioning hole improves the positional constraint, allowing the height to be locked by the external components passing through the second sliding groove. By setting a third sliding groove, an additional sliding area is added, making the external components fixed on the column slide more smoothly and convenient for training personnel to use.

[0023] Furthermore, hook assemblies are provided on the columns of the first and second support frames. The hook assembly includes a support part and a mounting part. The support part is an L-shaped column. One side of the mounting part is fixedly connected to the support part, and the other side of the mounting part is provided with a first fixing part. The first fixing part is slidably disposed in the second sliding groove. The first fixing part is fixed on the second sliding groove by a locking member passing through a positioning hole. The mounting part is provided with second limiting parts on both sides of the first fixing part. The second limiting parts are arranged opposite to each other on both sides of the first fixing part and are slidably disposed in the third sliding groove.

[0024] The above configuration, through the support part of the hook assembly, allows the horizontal section of the L-shaped column to provide the main support for the barbell placed on it, while the vertical section extends upward, allowing the barbell to roll and slide down the horizontal section. The first fixing part can move along the height of the column to a suitable height. A locking member passes through the positioning hole to fix the first fixing part to the second sliding groove, enabling height adjustment. The second limiting part, with its defined shape, allows it to slide within the third sliding groove while reducing sliding resistance. The simultaneous sliding of the first fixing part and the second limiting part on the sliding groove makes it smoother for the trainee to adjust the height of the hook assembly, improving the device's practicality.

[0025] Another aspect of the technical solution provided by the present invention is: a multi-functional training method for sports, implemented by a multi-functional training device for sports as described in any of the above claims, wherein the multi-functional training device for sports is internally provided with a data acquisition module, a judgment module, a prompting module and a guidance module; It also includes the following steps: S1. Rotate the training board to a horizontal surface and fix it to the horizontal surface by passing the fasteners through the mounting holes at the bottom of the first support frame and the third mounting hole in sequence. S2. Open the baffle and take out the first pad from the internal storage cavity. Align the position of the second magnetic plate on the first pad with the position of the first magnetic plate on the training plate, and place the rolling assembly on the first sliding groove. S3. When the first pressure sensor acquires the leg pressure signal on the training board and the hand pressure signal from the second pressure sensor on the support board, the drive device drives the second rotating shaft to rotate, which flips the display component upward to be perpendicular to the training board. S4. The data acquisition module synchronously acquires the pressure data from the first pressure sensor and the second pressure sensor. The judgment module compares the pressure data with a preset threshold. If the comparison result matches the preset result, S4.1 is executed. If the comparison result does not match the preset result, S5 is executed. S4.1 The display screen outputs the results; S5. The display screen outputs a prompt message and simultaneously retrieves and plays the correct demonstration video. S6. When the data acquisition module fails to acquire a pressure signal, the drive device drives the second rotating shaft to rotate, which will retract the display component and rotate the training board around the first rotating shaft to a vertical position.

[0026] The above method ensures the stability of the device by rotating the training board to fix its position on a level surface, preventing horizontal displacement or tilting under load. Aligning the second magnetic plate with the first allows the first pad to be quickly positioned and installed on the training board via magnetic attraction. Simultaneous triggering of the display component by the first and second pressure sensors improves reliability and avoids interference with training posture caused by manual operation. The data acquisition module synchronously collects pressure data, which is then compared by the judgment module to reflect the force situation at any given moment. Outputting positive prompts or demonstration videos provides timely positive feedback to the trainee and corrects errors, shortening the duration of incorrect movements and improving training efficiency. The display component automatically resets after the trainee stands up, preventing accidental collisions due to forgetting to store the device. The storage cavity stores other accessories, reducing the device's space requirements and ensuring reliable and convenient use. Attached Figure Description

Detailed Implementation

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0041] Example 1.

[0042] like Figures 1 to 11 As shown, a multi-functional training device for sports includes a first support frame 11, a second support frame 12, and a connecting component 5. The first support frame 11 and the second support frame 12 are respectively disposed on the front and rear sides of the training device. Both the first support frame 11 and the second support frame 12 are made of metal profiles to ensure sufficient structural strength to withstand the load generated during training.

[0043] The training device also includes a training plate 2, which is a flat plate structure with a certain thickness and a rectangular cross-section. The top surface of the training plate 2 is set as the working surface for the trainees during training. A baffle 21 is provided on one side of the training plate 2. The four corners of the baffle 21 are respectively provided with first mounting holes 2101 that penetrate through the thickness direction of the baffle 21. The side of the training plate 2 is provided with threaded holes at positions corresponding to the four first mounting holes 2101. Fasteners are threaded through the first mounting holes 2101 and then threadedly connected to the threaded holes on the side of the training plate 2, so that the baffle 21 can be detachably connected to the side of the training plate 2. At the same time, a storage cavity is provided inside the training plate 2, so that the storage cavity inside the training plate 2 is sealed by the baffle 21. The storage cavity is a hollow cavity formed by the top plate, bottom plate and surrounding side walls of the training board 2. The inside of the storage cavity is used to store various training accessories. When the fastener is unscrewed and the baffle 21 is removed, the opening of the storage cavity is opened, and the trainee can take out and put in the accessories through the opening. When the baffle 21 is fixed to the side of the training board 2 by the fastener, the storage cavity is completely closed and the internal accessories cannot slide out.

[0044] In this embodiment, the fastener is a screw.

[0045] like Figure 3 and Figure 4As shown, a mounting groove 22 is provided at the end of the training board 2 furthest from the first support frame. The mounting groove 22 is a recess formed by the top surface of the training board 2 being recessed downwards. A display component 24 is rotatably mounted in the mounting groove 22. The display component 24 is used to provide trainees with training guidance videos, action feedback information, and parameter display functions. First rotating shafts 23 are respectively provided on both sides of the other end of the training board 2. The first rotating shafts 23 are cylindrical shafts. One end of the first rotating shaft 23 is fixedly connected to the side of the training board 2, and the other end of the first rotating shaft 23 is connected to the second support frame. The support frame 12 is rotatably connected, and a shaft hole is provided at the bottom of the second support frame 12. The other end of the first rotating shaft 23 is inserted into the shaft hole, allowing the training board 2 to rotate relative to the first rotating shaft 23 in a vertical plane. When the training board 2 rotates to a horizontal position, it lies flat on the ground, suitable for various ground training movements. When the training board 2 flips upward around the first rotating shaft 23 to a vertical position, the entire training board 2 is stored between the first support frame 11 and the second support frame 12, reducing the space occupied by the device and facilitating storage and transportation. The end face of the other end of the training board 2 is an arc surface 20, which allows the end of the training board 2 to avoid collision with the horizontal ground during rotation around the first rotating shaft 23, ensuring smooth rotation.

[0046] The display component 24 includes a display screen 241 and a rotating part 242. The display screen 241 faces the trainee to display image information. The display screen 241 is fixedly connected to the rotating part 242. A second rotating shaft 2421 is disposed inside the rotating part 242. The two ends of the second rotating shaft 2421 extend out of the two side end faces of the rotating part 242, and shaft holes are respectively opened on the top two side walls of the mounting groove 22. The two ends of the second rotating shaft 2421 are respectively inserted into the shaft holes on the top two side walls of the mounting groove 22, thereby realizing the rotational connection between the second rotating shaft 2421 and the top of the mounting groove 22, so that the display component 24 can rotate up and down within the mounting groove 22. When the display component 24 is not in use, the display screen 241 is embedded in the mounting groove 22. When the display component 24 is in use, the display screen 241 is rotated upward to be perpendicular to the top surface of the training board 2, making it convenient for the trainee to view. A drive device (not shown in the figure) is installed inside one end of the training board 2. The drive device is a servo motor, and the output shaft of the drive device is connected to one end of the second rotating shaft 2421 through a transmission mechanism (not shown in the figure). The drive device drives the second rotating shaft 2421 to rotate through the transmission mechanism, thereby driving the display component 24 to flip up and down.

[0047] One or more first magnetic plates 25 and first pressure sensors 27 are respectively provided on both sides of the top of the training board 2. The first magnetic plates 25 are embedded inside the training board 2 and do not protrude from the surface of the training board 2, so that the top surface of the first magnetic plates 25 is flush with the top surface of the training board 2. The first pressure sensors 27 are also embedded inside the training board 2, and the sensing surface of the first pressure sensors 27 is flush with the top surface of the training board 2. The first pressure sensors 27 can sense and output the pressure data of the covered area in real time. A first sliding groove 26 is provided between the two first magnetic plates 25. The first sliding groove 26 is located in the central area of ​​the training board 2 and extends along the length of the training board 2. The first sliding groove 26 is formed by a downward indentation from the top surface of the training board 2, so that a guide channel with a certain depth and width is formed inside the training board 2. In this embodiment, there are six first magnetic plates 25, which are respectively set at symmetrical positions on both sides of the top of the training board 2. Each first magnetic plate 25 is set as a rectangle. There are two first pressure sensors 27, so that when the trainee supports his legs above the first pressure sensors 27, pressure data at the corresponding positions can be collected.

[0048] like Figure 4 and Figure 5 As shown, a rolling assembly 3 is slidably disposed inside the first sliding groove 26. The rolling assembly 3 includes a rotating wheel 31 and a support plate 32. The rotating wheel 31 is disposed on both sides of the bottom of the support plate 32. The rotating wheel 31 is a circular wheel and contacts the bottom surface of the first sliding groove 26. The support plate 32 is a flat plate structure. The top surface of the support plate 32 is a support plane used to support the elbow or forearm of the trainee. A second pressure sensor 33 is disposed on the top surface of the support plate 32. The sensing surface of the second pressure sensor 33 is flush with the top surface of the support plate 32. A handrail 34 is fixedly installed at one end of the mounting groove 22. The handrail 34 has a U-shaped structure, and both ends of the handrail 34 are fixedly connected to the two sides of the support plate 32. The handrail 34 is convenient for the trainee's hands to grip. When the rolling component 3 is slidably installed in the first sliding groove 26, the rotating wheel 31 is embedded in the bottom of the first sliding groove 26. The support plate 32 is located above the first sliding groove 26. There is a gap between the bottom surface of the support plate 32 and the top surface of the training plate 2 to ensure that the support plate 32 does not contact the top surface of the training plate 2 during the sliding process of the rolling component 3.

[0049] like Figures 6 to 8As shown, in another embodiment, to prevent the rolling assembly 3 from detaching in the vertical direction of the training plate 2, a first sliding groove 261 is provided between the first sliding grooves 26 on the training plate 2. The first sliding groove 261 is parallel to the first sliding groove 26. A notch is provided on the side wall of the first sliding groove 261. A second sliding groove 262 extending along the length direction of the first sliding groove 261 is provided on the first sliding groove 261. A fixing plate 35 is provided between the rotating wheels 31. The fixing plate 35 is located below the support plate 32. The fixing plate 35 is provided with one or more guide holes on both sides facing the rotating wheels 31. A positioning mechanism 36 is provided inside the fixing plate 35. The positioning mechanism 36 includes a drive motor 361, a turntable 362, and a sliding block 363. The drive motor 361 is mounted on the turntable 362, and the output end of the drive motor 361 is rotatably connected to the turntable 362. A guide groove 3621 is provided on the turntable. The guide groove 3621 extends along the rotation direction. The outer arc surface of the disc 362 extends outwards. A guide member 3631 is fixedly connected to the sliding block 363. The sliding block 363 is slidably connected to the guide groove 3621 through the guide member 3631. The guide groove 3621 is arc-shaped along the circumference of the disc 362. The distance from one end of the guide groove 3621 to the center of the disc 362 is less than the distance from the other end of the guide groove 3621 to the center of the disc 362. The sliding block 363 corresponds to the guide hole 350 on the fixed plate 35. Thus, the guide groove 3621 is eccentrically set on the disc 362. When the disc rotates, the sliding block 363 is limited by the guide hole 350. The length of the sliding block 363 extending out of the guide hole is different as the guide member 3631 slides in the guide groove 3621. To further enhance the reliability of the extension movement of the sliding block 363, a slide rail is provided at the bottom of the fixed plate, and a groove is provided on the sliding block 363 corresponding to the slide rail to achieve the limitation. The support plate 32 is also equipped with a button 37, which is electrically connected to the drive motor 361. When the rotating wheel 31 is embedded in the bottom of the first sliding groove 26, the fixing plate 35 is simultaneously embedded in the first sliding groove 261. Pressing the button 37 starts the drive motor 361 and drives the turntable 362 to rotate. The sliding block 363 slides along the guide groove 3621 under the rotation of the turntable 362, so that the sliding block 363 extends out from the guide holes on both sides of the rotating wheel 31. After extending, the sliding block 363 enters the second sliding groove 262 and slides in the second sliding groove 262. The sliding of the sliding block 363 in the second sliding groove 262 prevents the rolling assembly 3 from coming off in the vertical direction of the first sliding groove 26 or the first sliding groove 261 when it slides on the training plate 2, thereby affecting the stability of the rolling assembly 3. By pressing the button 37, the forward and reverse rotation of the drive motor 361 is controlled, thereby controlling the extension and retraction of the sliding block 363. In this embodiment, the drive motor 361 is a small DC motor.

[0050] like Figure 8As shown, the top of the training board 2 is also provided with a first pad 41 and one or more second pads 42. The first pad 41 and the second pad 42 are both flexible pads used to provide a comfortable support surface for the knees, elbows or back of the trainee. The shapes of the first pad 41 and the second pad 42 correspond to those of the training board 2. The bottom surfaces of the first pad 41 and the second pad 42 are each provided with a second magnetic plate. The shape and position of the second magnetic plate correspond to the first magnetic plate 25 on the training board 2. When the first pad 41 or the second pad 42 is placed on the training board 2, the second magnetic plate and the first magnetic plate 25 generate an attractive magnetic force, which attracts and fixes the pad to the top surface of the training board 2. The top surface of the first pad 41 is provided with a contact area 411. The position of the contact area 411 corresponds to the position of the first pressure sensor 27. The thickness of the contact area 411 is smaller than that of other areas of the first pad 41. On the one hand, the contact area 411 can indicate the area where the foot collects pressure. On the other hand, it can also facilitate the foot to collect foot pressure signals more accurately through the contact area 411. When the first pad 41 is fixed on the training board 2 by the magnetic attraction between the second magnetic plate and the first magnetic plate 25, the contact area 411 is exactly above the first pressure sensor 27. There are two second pads 42, which correspond to the positions of the first magnetic plates 25 on both sides of the top of the training board 2. The two second pads 42 can be magnetically fixed to both sides of the training board 2 independently to support other parts of the trainee. Through the first pad 41 and the two second pads 42, the trainee can be provided with multi-point support to meet the needs of different training movements.

[0051] like Figure 1 and Figure 2 As shown, connecting components 5 are respectively provided between the top of the first support frame 11 and the bottom of both sides of the second support frame 12. There are five connecting components 5. Each connecting component 5 includes a sleeve 51 and a connecting rod 52. The sleeve 51 is a hollow cylinder. The inner hole shape of the sleeve 51 is adapted to the outer shape of the connecting rod 52. One end of the sleeve 51 is fixedly connected to the first support frame 11, and the other end of the sleeve 51 is a free end. A radially penetrating sleeve 51 is provided on the tube wall near the free end of the sleeve 51. The pipe wall has a through hole. The connecting rod 52 is cylindrical and its outer diameter is adapted to the inner diameter of the sleeve 51, so that the connecting rod 52 can be inserted into the inside of the sleeve 51 axially. One end of the connecting rod 52 is fixedly connected to the second support frame 12, and the other end of the connecting rod 52 is a free end for insertion into the inside of the sleeve 51. The connecting rod 52 is provided with one or more through holes. The first support frame 11 and the second support frame 12 are fixedly connected by fasteners passing through the through holes on the sleeve 51 and the connecting rod 52 in sequence.

[0052] like Figure 4 and Figure 9As shown, the training board 2 has a second mounting hole 28 and a third mounting hole 29 on both sides. The second mounting hole 28 is located at one end of the training board 2, and the third mounting hole 29 is located in the middle of the training board 2. The bottom of the first support frame 11 and the top of the second support frame 12 are both provided with through holes 110. The horizontal distance between the third mounting hole 29 and the first rotating shaft 23 is equal to the horizontal distance between the bottom of the first support frame 11 and the bottom of the second support frame 12. When the training board 2 rotates around the first rotating shaft 23 to a horizontal state, the fasteners are passed through the bottom through hole 110 and the third mounting hole 29 of the first support frame 11 in sequence and fixed, thereby locking the horizontal state of the training board 2. When the training board 2 rotates around the first rotating shaft 23 to a vertical storage state, the fasteners are passed through the top through hole and the second mounting hole 28 of the second support frame 12 in sequence and fixed, thereby locking the vertical storage state of the training board 2. Through the cooperation of the second mounting hole 28 and the third mounting hole 29 with the through hole, the switching and fixing of the training board 2 in the horizontal working state and the vertical storage state are realized.

[0053] like Figures 9 to 11 As shown, the columns of the first support frame 11 and the second support frame 12 are both vertically arranged slender structures with a rectangular cross-section. Second sliding grooves 15 are respectively provided on the front and rear sides of the columns. Each second sliding groove 15 is a strip-shaped groove extending along the length of the column, formed by indentation from the surface of the column. Two or more positioning holes 16 are provided through the interior of each second sliding groove 15, equidistantly arranged along the length of the second sliding groove 15. The positioning holes 16 are used to lock the height position of external components within the second sliding groove 15. Third sliding grooves 17 are also respectively provided on the left and right sides of the columns of the first support frame 11 and the second support frame 12. Each third sliding groove 17 is a strip-shaped groove extending along the length of the column, formed by indentation from the surface of the column, and the cross-sectional shape of the indentation is semi-circular.

[0054] Hook assembly 6 is provided on the uprights of the first support frame 11 and the second support frame 12. Hook assembly 6 is used to suspend barbell bar 13. Hook assembly 6 includes support part 61 and mounting part 62. Support part 61 is an L-shaped rigid column, consisting of a horizontal section and a vertical section. One end of the horizontal section is fixedly connected to one end of the vertical section. The other end of the horizontal section is a free end that extends vertically upward. The horizontal section of support part 61 is used to support the weight of the barbell bar 13 suspended above. The vertical section extends upward to form a limiting stop for the barbell bar 13 placed on the horizontal section, preventing the accessory from rolling along the length of the horizontal section and slipping off the free end. One side of the mounting part 62 is fixedly connected to the support part 61, and the other side of the mounting part 62 is provided with a first fixing part 63. The shape of the first fixing part 63 is adapted to the cross-sectional shape of the second sliding groove 15. The first fixing part 63 is embedded in the second sliding groove 15 and can slide up and down along the extension direction of the second sliding groove 15. A through fixing hole is provided on the first fixing part 63, and the position of the fixing hole corresponds to the position of the positioning hole 16. The first fixing part 63 is fixed to the second sliding groove 15 by a locking member 65 passing through the positioning hole 16 and the fixing hole, so that the height of the hook assembly 6 on the column is fixed. The mounting part 62 is also provided with a second limiting part 64, which is located at the first fixing part 63. The two sides are arranged opposite each other. The cross-sectional shape of the second limiting part 64 corresponds to the cross-sectional shape of the third sliding groove 17. The second limiting part 64 is embedded in the third sliding groove 17 and can slide up and down along the extension direction of the third sliding groove 17. The second limiting part 64 is rotatably set on the first fixing part 63. The second limiting part 64 has a semi-circular cross-section and protrudes from the first fixing part 63. After installation, one side of the first fixing part 63 is in contact with the top surface of the third sliding groove 17. The second limiting part 64 is made of a material with a certain elasticity, so that the second limiting part 64 slides into the third sliding groove 17. By setting the semi-circular cross-section, the sliding of the hook assembly 6 on the column is smoother.

[0055] Five through holes are equidistantly arranged on the crossbeam at the top of the first support frame 11. Two insert handles are inserted into two of the through holes, and bolts are provided at the other end of the insert handles to fix them in the through holes. This allows trainees to perform exercises such as pull-ups using the handles, increasing the versatility of the device's training functions. By selecting the form of pulling out and inserting the handles, different spacing between the handles can be chosen to meet different training needs. The structure of fixing the handles to the through holes is existing technology and will not be described here.

[0056] The working principle of this invention: The training board 2 is rotatably connected to the second support frame 12 via a first rotating shaft 23 at both ends, allowing the training board 2 to rotate around the first rotating shaft 23, thus switching between a horizontal working state and a vertical storage state. When the training board 2 is placed horizontally on the ground, it is locked by fasteners passing through the through hole at the bottom of the first support frame 11 and the third mounting hole 29 in the middle of the training board 2, providing a stable training support plane. When stored vertically, the training board 2 is locked by fasteners passing through the through hole at the top of the second support frame 12 and the second mounting hole 28 at the end of the training board 2, reducing storage space. A display component 24 is provided in the mounting groove 22 at one end of the training board 2. Driven by the internal drive device of the training board 2, it rotates around the top of the mounting groove 22 via the second rotating shaft 2421, allowing the display screen 241 to flip upward from the storage position. After use, the drive device reverses. Rotating the display assembly 24 retracts it into the mounting slot 22 to avoid external collisions. The first magnetic plates 25 on both sides of the top of the training board 2 generate magnetic attraction with the second magnetic plates on the bottom of the first pad 41 or the second pad 42, realizing the positioning and installation / removal of the pad. The first pressure sensor 27 is used to sense foot pressure, and works with the second pressure sensor 33 on the top surface of the support plate 32 in the rolling assembly 3 in the first sliding groove 26 to sense elbow pressure, providing pressure data for subsequent action analysis. The horizontal distance between the first support frame 11 and the second support frame 12 is adjusted by the connecting assembly 5. The fasteners pass through the through holes at the end of the sleeve 51 and the through holes at different positions on the connecting rod 52 to achieve locking at different positions to adapt to different training or storage width requirements. The second sliding grooves 15 on the front and rear sides of the column and the third sliding grooves 17 on the left and right sides provide guidance for the sliding and fixing of the hook assembly 6.

[0057] Example 2.

[0058] like Figures 1 to 11 As shown, a multi-functional training method for sports is implemented through a multi-functional training device for sports in Embodiment 1. The display component 24 is internally equipped with a data acquisition module, a judgment module, a prompting module, and a guidance module. It also includes the following steps: S1. Rotate the training board 2 to lay it flat on a horizontal surface, and fix the training board 2 on the horizontal surface by passing the fasteners through the through hole at the bottom of the first support frame 11 and the third mounting hole 29 in sequence. S2. Open the baffle 21 and take out the first pad 41 from the internal storage cavity. Align the positions of the second magnetic plate on the first pad 41 and the first magnetic plate 25 on the training plate 2, and align the contact area 411 above the first pressure sensor 27. Place the rolling assembly 3 on the first sliding groove 26. S3. The trainee kneels on the contact area 411 and grabs the handle 34 of the rolling component 3, pressing his elbows onto the support plate 32. The first pressure sensor 27 below the contact area 411 and the second pressure sensor 33 on the support plate 32 receive pressure sensing signals. When the pressure signal is detected, the drive device drives the second rotating shaft 2421 to rotate, which flips the display component 24 upward to be perpendicular to the training plate 2. S4. The data acquisition module synchronously acquires the pressure data of the first pressure sensor 27 and the second pressure sensor 33. The judgment module compares the pressure data with a preset threshold. If the comparison result meets the preset result, S4.1 is executed. If the comparison result does not meet the preset result, S5 is executed. S4.1 The display screen 241 outputs positive feedback to inform the trainee that the action is correct; S5, Display screen 241 outputs prompt information and simultaneously retrieves the correct demonstration video from the internal database for playback; S6. After the trainee gets up and leaves, the data acquisition module cannot detect the pressure signal. The drive device drives the second rotating shaft 2421 to rotate, and the display component 24 is retracted. At the same time, the trainee retracts the first pad 41 into the storage cavity and fixes the baffle 21 back to its original position. The training board 2 is rotated around the second support frame to make the training board stand in a vertical position for storage.

[0059] Rotating the training plate 2 fixes its position on a horizontal surface, preventing horizontal displacement or tilting under load and ensuring the stability of the device. Aligning the second magnetic plate with the first magnetic plate 25 allows the first pad 41 to be quickly positioned and installed on the training plate 2 via magnetic attraction. The contact area 411 ensures pressure signal transmission, preventing positional deviation between the contact area 411 and the first pressure sensor 27, thus improving the accuracy of pressure data acquisition. Simultaneous triggering of the display component 24 by the first pressure sensor 27 and the second pressure sensor 33 enhances the device's reliability and eliminates the need for manual operation by the trainee. To mitigate interference with training posture, the data acquisition module synchronously collects pressure data, which is then compared by the judgment module. This reflects the force situation at the same moment, making the judgment of the correctness of the movement more objective and clear, eliminating individual subjective differences. By outputting positive prompts or demonstration videos, it provides timely positive feedback to trainees and corrects errors in a timely manner, shortening the duration of incorrect movements, preventing trainees from exhausting themselves and improving training efficiency. The display component 24 automatically resets after the trainee stands up, preventing accidental collisions caused by forgetting to store the device. At the same time, the storage cavity stores other accessories, reducing the space occupied by the device and making it reliable and convenient to use.

[0060] Example 3.

[0061] like Figure 12 As shown, the difference between this embodiment and Embodiment 1 is that the connecting rod 52 is inserted into the sleeve 51 along the axial direction until the free end of the connecting rod 52 abuts against the first support frame 11. At the same time, the free end of the sleeve 51 approaches the second support frame 12 and is at its limit position. At this time, fasteners are passed through the through holes on the sleeve 51 and the through holes on the connecting rod 52 that are closest to the second support frame 12 in sequence to achieve a fixed connection. At this time, the horizontal distance between the first support frame 11 and the second support frame 12 is at its minimum value, which further reduces the space occupied between the first support frame 11 and the second support frame 12, so that the space occupied by the device is minimized when stored.
