Description

Technical Field

[0001] The invention relates to the technical field of fitness equipment, in particular to a multifunctional fitness door frame. Background Art

[0002] In modern society, the fitness industry is booming due to growing demand. However, while the traditional gym model provides people with exercise opportunities, it also exposes a series of problems that cannot be ignored.

[0003] First of all, the commuting time to the gym is long. Secondly, for novices, how to use the equipment correctly is the primary problem. At this time, they often need to hire a fitness coach. However, the cost of hiring a fitness coach is also a considerable expense, which may become a financial burden on their fitness journey. Novices are often embarrassed to ask others for advice because of their introverted and shy personalities. Even if there are experienced fitness people around, they may choose to explore alone for fear of disturbing others or being laughed at. This situation makes it impossible for them to solve the problems encountered in the fitness process in time, the mistakes are not corrected, the training effect is not good, and they fall into a vicious cycle of worse and worse training. Finally, the fluctuations in the economic environment have had a significant impact on the gym industry. In recent years, the unstable economic situation has caused many gyms to face operational difficulties, and the bankruptcy rate has increased year by year. In 2023, the bankruptcy rate of gyms reached an astonishing 10%. This phenomenon has caused a large number of fitness members to lose their fixed exercise venues and have to find a suitable way to exercise again. Summary of the invention

[0015] (III) Beneficial effects Compared with the prior art, the present invention provides a multifunctional fitness door frame, which has the following beneficial effects: The multifunctional fitness door frame is used by the cooperation of the exercise platform, the deformable bracket, the terminal and the gripping device, the adaptive walking module and the auxiliary support module. When using the fitness door frame for fitness, the reverse torque function of the brushless motor package and the rotation function of the rotary motor can be used to change the angle between the main bracket and the exercise platform, and the main bracket and the auxiliary bracket, so as to achieve the purpose of exercising muscles in different parts. Mode 1: For example, Figure 1 , when the main bracket and the slave bracket are fixed in a vertical state by the rotating motor and the brushless motor package, the electrostatic induction handle is located on the top of the user, and the user can perform pull-ups, hanging leg raises, etc. Mode 2: Control the main bracket and the slave bracket to move to Fig.14When the position is shown, the user can do a weighted squat. At this time, the slave bracket is fixedly connected to the brushless motor package, and the main bracket and the brushless motor package are connected through the reverse torque capacity of the brushless motor package, that is, a certain resistance is generated between the driving gear and the rack through the brushless motor package, so that the user feels as if there is a heavy object on the user's shoulders when squatting. Mode 3: As shown in Figure 3, the slave bracket is fixedly connected to the brushless motor package, and the brushless motor package is connected to the brushless motor package through the reverse torque capacity of the brushless motor package, that is, a certain resistance is generated between the driving gear and the rack through the brushless motor package, so that the user feels as if there is a heavy object on the user's shoulders when squatting. Fig.15 , the same principle as mode 2, you can do dumbbell press. Mode 4: Fig.16 , you can do dumbbell curls. Mode 5, such as Fig.17 , you can do sit-and-forward bend. Mode 5: Fig.18 , you can do backward pedaling. At the same time, by installing the auxiliary support module, you can unlock more exercise movements. Mode 6, such as Fig.19 , you can do barbell bench press. A total of 20 fitness movements are supported, which can cover 80% of the muscle groups of the human body.

[0016] When the user is exercising, the camera will emit an infrared light matrix to scan the human body, which will be reflected into the structured light receiving end. By recording the speed of each light point to the receiving end, the distance between the light point and the camera is recorded, thereby scanning the 3D model of the human body. The AI ​​data processing module will delete the redundant sampling parts of the camera and the repeatedly scanned human body fragments. At the same time, it will reduce the dimension of tens of millions of light points and continuously merge similar light points until a rough human body outline is formed. At the same time, the projection module will project the correct movements to help users find the correct feeling of force. During projection, the picture will be synchronized with the user's movements to facilitate self-correction. The human-computer interaction module will display the user's physical condition during exercise so that users can understand their exercise effects in real time. They can also use wifi to upload data to the mobile phone app, making it easier for users to check their physical condition.

[0017] By installing the adaptive walking module, the user's lower limb strength can be trained and the user's cardiopulmonary function can be enhanced. The user first needs to fix his or her feet in the footrest. When fixed, the fasteners on the second adjustable telescopic rod are disengaged from the fixed columns on both sides of the ankle cuff. At this time, the ankle cuff can be rotated upward by a certain angle. The user passes his or her sole through the ankle cuff so that the ankle cuff reaches the position of his or her ankle. Then the entire sole of the foot steps on the three support blocks, and ensures that each part of the sole of the foot corresponds to the position of the three support blocks. Finally, the fasteners on the left and right sides of the second adjustable telescopic rods are fastened to the fixed columns on the left and right sides of the ankle cuff. At this time, the user's feet will be fixed. Then the user can stand up and start walking slowly. When the user is standing, the pedal will adapt to the contour of the user's foot and wrap it. Specifically, when the user is standing, the body weight is applied to the forefoot support block, the sole support block and the heel support block, and the forefoot support block, the sole support block and the heel support block will sink downward. At this time, the self-adjusting parts at the bottom of the forefoot support block and the heel support block will expand outward until they adapt to the length of the user's foot. Since the forefoot support block, the sole support block and the heel support block are hinged together and the sole support block is located in the middle, and the forefoot support block and the heel support block are stepped on outward and downward, since there is an arch on the sole of the human body, the sole support block will fit upward at the arch of the sole of the human body. While the forefoot support block, the sole support block and the heel support block adapt to the bottom of the sole, the first adjustment telescopic rod and the second adjustment telescopic rod will also automatically adjust their lengths to adapt to the length of the user's instep and the side of the foot due to the user's standing. After the user has completely stood up, the pedal will automatically fit the user's sole. Through this adaptation, it is ensured that users can easily achieve the maximum balance state during each exercise, making the user's exercise more stable and efficient, supporting the soles of the feet and dispersing the pressure on the feet.

[0018] When the user starts walking, the slider, the first connecting rod, the second connecting rod and the foot pedal will change their positions accordingly with the movement of the user's feet. The slider, the first connecting rod and the second connecting rod are connected to each other through multiple structures, and multiple single degrees of freedom are connected in series to form a multiple degree of freedom structure, so as to better adapt to the complex movement trajectory of the user's feet. When the user walks, the semiconductor sheet in the sole support block will cut the magnetic field generated by the magnetic field base, and a voltage difference will be generated on both sides of the sheet when the semiconductor sheet moves in the magnetic field. By measuring this voltage difference and combining it with the known parameters of the current and magnetic field, the movement position speed of the mechanism can be monitored and measured, thereby realizing the calculation of the walking distance and calorie consumption of the walking mechanism.

[0019] Thereby achieving the effect of exercising the whole body at home, occupying a small area, being economical and practical, and real-time monitoring, tracking, guiding and correcting the user's exercise. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-2A multifunctional fitness door frame includes an exercise platform 1, which is a platform for users to stand or lie down when exercising. The exercise platform 1 can provide a stable support surface so that users can safely perform various movements, and its size is small and occupies a small area. Deformable brackets 2 are arranged on both sides of the exercise platform 1, respectively, and the deformable brackets 2 can change their shapes and simulate weights to adapt to the user's exercise of different parts. By changing the shape of the brackets, the angle, height or position of the exercise can be adjusted, so as to exercise specific muscle groups. The tops of the two deformable brackets 2 are connected with a terminal and a gripping device 3, which can monitor and correct the user's exercise posture and provide a gripping position. The terminal and gripping device 3 is a device that integrates multiple functions. The device can monitor the user's exercise posture to ensure that the user maintains a correct posture when performing an action to avoid injury. If the user's posture is detected to be incorrect, the device can provide feedback to help the user adjust the posture. The device also provides a gripping position so that the user can hold it stably when exercising, increasing the stability and safety of the action.

[0024] See also Fig.10 The exercise platform 1 is also provided with a detachable adaptive walking module 4 and an auxiliary support module 5. These two modules can be removed when not in use, so that the use of the deformable bracket 2 is more convenient. When needed, the two modules are installed on the exercise platform 1 and then the corresponding exercise is performed.

[0025] Two adaptive walking modules 4 are arranged on the exercise platform 1, corresponding to the left and right feet of the user respectively. The adaptive walking modules 4 are adaptively adjusted according to the walking movements of the user to conform to the natural walking curve of the human body. Through intelligent adjustment, the adaptive walking modules 4 can better fit the user's pace, reduce the impact and discomfort during exercise, and help the user maintain balance and prevent falling.

[0026] The auxiliary support module 5 is used to support the user during exercise and can act as a seat or a reclining board. For example, when performing a bench press, the auxiliary support module 5 acts as a reclining board, so that the user can lie on it and perform bench press training.

[0027] See also Figure 3 The exercise platform 1 is provided with side platforms 11 on both sides thereof, and the side platforms 11 are provided with mounting notches 111. The side platforms 11 are located on both sides of the exercise platform 1, and are used to support two deformable brackets 2 respectively, and the mounting notches 111 are used to install the bottom bracket 24 at the bottom of the deformable bracket 2, so as to support the deformable bracket 2.

[0028] Two clearance slots 12 are also provided in the middle of the exercise platform 1. The adaptive walking module 4 is installed in the clearance slots 12. The fitting blocks 24113 are embedded in the clearance slots 12 for fixing the adaptive walking module 4. The clearance slots 12 provide a fixed installation position for the magnetic field base 41 of the adaptive walking module 4. The fitting blocks 24113 are used to close the clearance slots 12 and fix the magnetic field base 41. The fitting blocks 24113 are designed with a size and shape matching the clearance slots 12. The clearance slots 12 are closed by fitting, and the magnetic field base 41 is ensured to be firmly fixed on the exercise platform 1. This can not only prevent the magnetic field base 41 from loosening or falling off, but also improve the neatness and aesthetics of the entire device.

[0029] The exercise platform 1 is also provided with a mounting hole 14, in which the auxiliary support module 5 is mounted. The mounting hole 14 is used to mount a mounting base 51 on the auxiliary support module 5.

[0030] See also Figure 4-6 The deformation bracket 2 includes a bottom bracket 24, a main bracket 23, a brushless motor package 22 and a slave bracket 21 which are rotatably connected in sequence. The deformation bracket 2 is formed by the bottom bracket 24, the main bracket 23, the brushless motor package 22 and the slave bracket 21 being rotatably connected to each other. Through the rotational connection of multiple components, the degree of freedom is greatly improved, so that the number of forms that the deformation bracket 2 can change is greatly increased, and the corresponding muscles in different parts that can be trained are more. The bottom of the bottom bracket 24 is also provided with a fitting block 24113, and the bottom bracket 24 is installed in the installation slot 111 of the side platform 11 through the fitting block 24113.

[0031] A rotating motor 236 is provided at the rotating connection between the main bracket 23 and the bottom bracket 24. During the process of the deformation bracket 2 changing its shape, the bottom bracket 24 is a base and does not need to rotate, while the main bracket 23, the brushless motor package 22 and the slave bracket 21 above it need to change their angles. The rotating motor 236 is used to drive the rotation of the main bracket 23, thereby changing the angle of the main bracket 23.

[0032] A rack 233 is provided on the inner side of the main bracket 23, and a brushless motor package 22 is installed on the top of the rack 233. A drive shaft 221 and a drive gear 222 are provided on the brushless motor package 22, and the drive gear 222 and the rack 233 are meshed with each other. The brushless motor package 22 has the function of reverse torque, which is used to control the shape transformation of the deformable bracket 2 and infinitely adjust the weight. It can accurately simulate the weight and motion trajectory generated by the dumbbells during fitness. Whether it is a lightweight warm-up training or a high-intensity strength challenge, it can be achieved by regulating the reverse torque, providing users with a resistance feeling that is almost consistent with real dumbbell exercises. The brushless motor handle contains two brushless motors, which simulate the motion trajectory of different equipment by rotating and reciprocating straight lines, and simulate the weight of different training by applying reverse torque to increase or reduce resistance. In addition, the brushless motor package 22 is also responsible for controlling the shape change of the deformation bracket 2. The brushless motor package 22 can change the relative position of the brushless motor package 22 on the main bracket 23, and change the relative position and angle between the slave bracket 21 and the main bracket 23, so as to achieve the full shape change of the deformation bracket 2 to meet the needs of different exercise parts. When the user wants to exercise the upper limb muscles, the brushless motor package 22 operates to quickly adjust the deformation bracket 2 to a posture suitable for upper limb training; and when the user turns the goal to lower limb training, the brushless motor package 22 operates to convert the deformation bracket 2 into the best lower limb training posture.

[0033] The slave bracket 21 is provided with a first connection port 211 and a second connection port 212, and the drive shaft 221 is assembled in the second connection port 212 of the slave bracket 21. The drive shaft 221 is fixedly connected to the second connection port 212, and the brushless motor in the brushless motor package 22 can drive the drive shaft 221 to change the shape and angle of the slave bracket 21.

[0034] The inner side of the main bracket 23 is also embedded with an array of cameras 232. The camera 232 is a TrueDepth camera 232. The principle of the TrueDepth (real-time modeling) camera 232 system is to project a specific pattern of light onto the surface of an object, and then obtain the three-dimensional shape and contour information of the object based on the deformation and reflection of the light. When applied to human body modeling in motion, the TrueDepth camera 232 can capture the posture, joint angles and muscle movement trajectory of the human body in various fitness movements in real time. When the user is doing fitness exercises, the TrueDepth camera 232 can accurately analyze every movement of the user. Whether it is the arm extension when lifting weights or the stride amplitude when running, it can provide detailed data. For fitness enthusiasts, this means more accurate movement evaluation. Users can clearly understand whether their movements are standard and correct irregular postures in time, thereby reducing the risk of injury and maximizing the effect of each exercise. In strength training, the TrueDepth camera 232 can help users determine the force points and load distribution of muscles, optimize training plans, enable users to exercise target muscle groups more specifically, and improve the efficiency of strength growth. For aerobic exercises, such as running or skipping rope, it can analyze the user's movement rhythm and body balance, help users improve sports skills, and enhance endurance performance. In addition, the TrueDepth camera 232 can also track the user's fitness progress for a long time. Through multiple measurements and comparisons, users can intuitively see the changes in body shape, muscle growth and fat loss, providing a strong driving force and clear direction for the user's fitness journey. The specific steps are: the camera 232 will emit an infrared light matrix to scan the human body, reflect it into the structured light receiving end, and record the distance between the light spot and the camera 232 by recording the speed of each light spot to the receiving end, so as to scan the human body 3D model. The AI ​​data processing module 32 will delete the redundant sampling parts of the camera 232 and the repeatedly scanned human body fragments. At the same time, it will reduce the dimension of tens of millions of light spots, and continuously merge similar light spots until a rough human body outline is formed.

[0035] A projection module 231 is provided on the outer surface of the main support 23. When the user makes a mistake in the fitness exercise, the projection module 231 will project the correct action picture, and the projection picture will match the user's action in real time, so that the user can directly compare his own action with the standard action in the same perspective, so as to quickly detect and correct the error. This intuitive visual guidance significantly enhances the user's understanding and grasp of the action norms, which is conducive to more efficient and safer fitness training. When the fitness door frame is not in use, the projector can also be used to play movies and other entertainment videos for the user.

[0036] A limiting device 234 is also provided at the bottom of the main bracket 23, and a limiting block 235 is provided inside the limiting device 234. The limiting device 234 is used to prevent the motor from being driven in a non-working state. The limiting device 234 can detect abnormal operation of the brushless motor package 22 and the rotating motor 236. For example, if a software failure or other unexpected factors cause the brushless motor package 22 and the rotating motor 236 to start abnormally, the limiting block 235 will pop out to limit the rotation of the rotating motor 236, thereby preventing the main bracket 23 from rotating, effectively avoiding sudden movement of the deformed bracket 2, and reducing the risk of accidental injury to the user.

[0037] See also Figure 7-8 , the terminal and the holding device 3 are installed in the first connection ports 211 of the two oppositely arranged slave brackets 21, and the terminal and the holding device 3 include three parallel spliced ​​human-computer interaction modules 31, AI data processing modules 32 and central data processing modules 33. A display screen is provided on the human-computer interaction module 31, which can display various data and physical conditions of the human body in real time. This module can display the user's key motion data in real time. During the user's exercise, the display screen will clearly inform the user how many calories have been burned, so that the user can see his energy consumption at a glance. In addition, the display screen will also intelligently display the next training plan according to the user's fitness goals and progress. Whether it is to increase strength, improve endurance or shape the body, these personalized training plans will accurately match the needs of the user to ensure that the user's exercise is scientific and efficient. Finally, the user can also switch the shape of the deformable bracket 2 through the display screen to adapt to the user's diverse fitness needs.

[0038] The AI ​​data processing module 32 is mainly used to process various collected human body data, analyze and integrate them, and then transmit them to the human-computer interaction module 31 or to the user's mobile phone. This module is based on deep learning and computer vision technology. First, the AI ​​model is trained with a large amount of human structured light data. These data contain human structured light information in different body shapes, postures and environments. During the processing, AI first uses a dimensionality reduction algorithm to map high-dimensional structured light data to a low-dimensional space, deleting a large amount of repeated sampling or structured light that is not related to the human body. Then AI uses feature extraction technology to gradually merge tens of millions of levels of structured light until the general outline of the human body can be seen. After the user's precise model is established through the camera 232 system, the muscle training state can be analyzed from multiple aspects. First, by analyzing the geometric shape and proportion of the model, the volume and dimensional changes of the muscle can be evaluated. Compare the models of different time periods and observe the thickening or elongation of the muscle groups to determine the degree of muscle growth or stretching. Secondly, use motion capture data and mechanical simulation to analyze the contraction and extension patterns of the user's muscles when performing various exercise movements. It is possible to determine which muscle groups play a major role in a specific movement, as well as the intensity and duration of their activity. Furthermore, combined with the principles of biomechanics, the force and load that the muscles bear during exercise can be calculated. If a muscle continues to bear too high or too low a load during multiple exercises, it can be inferred that it may be in a state of over-fatigue or under-exercise. In addition, the coordination and strength balance of the muscles can also be indirectly reflected by evaluating the posture and movement smoothness of the model. Unsmooth movements or abnormal postures may suggest that certain muscle groups are too tense or weak. With the help of knowledge of muscle fiber types, the activation and development of different types of muscle fibers (such as fast-twitch fibers and slow-twitch fibers) can also be inferred based on the user's exercise type and intensity.

[0039] The central data processing module 33 is used to receive various types of data.

[0040] The outer ends of the human-machine interaction module 31 and the central data processing module 33 are respectively provided with connectors 37, which are assembled in the first connection port 211 of the slave bracket 21. The connector 37 and the first connection port 211 are also fixedly connected, and when the shape and angle of the slave bracket 21 change, the terminal and the holding device 3 mounted in the middle can be driven to change shape together.

[0041] A thermal camera 38 is provided on the front side of the AI ​​data processing module 32. The thermal camera 38 is used to detect whether there are any living organisms around. Once a living organism is detected entering its detection range, the thermal camera 38 will immediately send a signal to the system to forcibly stop the machine from changing its form to avoid accidental damage to the living organism entering the screen during the change process.

[0042] The human-computer interaction module 31 and the central data processing module 33 are respectively provided with a slide bar 35, and an electrostatic induction handle 34 is slidably mounted on the slide bar 35. The electrostatic induction handle 34 can slide left and right on the slide bar 35 to correspond to the position change of the hand during the exercise. For example, in the process of dumbbell push-up, both hands grasp the electrostatic induction handles 34 on both sides, and make both hands above the shoulders, and the distance between the two hands is about two shoulder widths, and then push upward. In the process of gradually pushing upward, the distance between the two hands will gradually close, and the corresponding two electrostatic induction handles 34 will slide from both sides to the middle, until the push-up action is complete, and then both hands will drop. Similarly, at this time, the electrostatic induction handles 34 will move from the middle to both sides, and the cycle will be repeated.

[0043] The user's skin, as a conductive medium, will change the capacitance value of the sensor on the electrostatic induction handle 34. The sensor will continue to detect the change in capacitance value. When the capacitance value reaches a certain threshold, it indicates that the electrostatic induction handle 34 is in sufficient contact with the skin, and the motor will be driven. This has the effect of safety induction and contact start, improving safety.

[0044] See also Fig. 9 A foot fixer 36 is also provided at the bottom of the human-computer interaction module 31 and the central data processing module 33. When performing leg training such as back kicking, the user needs to lie down, then lift up his legs and place his feet in the foot fixer 36 for training. The foot fixer 36 fixes the user's feet to prevent slipping and ensure the safety of training.

[0045] The sole holder 36 includes a fixed base 361 embedded in the human-computer interaction module 31 and the central data processing module 33. The fixed base 361 has the same shape as the foot contour, but is slightly larger in size and is used to place the feet. A slide groove 364 is provided on the fixed base 361. Sliding stoppers 362 are slidably provided at both ends of the slide groove 364. The sliding stoppers 362 can slide in the slide groove 364. When the user places the feet on the fixed base 361, the toes and heels will step on the two sliding stoppers 362 respectively, and then the sliding stoppers 362 will move closer to each other to clamp the toes and heels of the user together.

[0046] Rotational stoppers 363 are rotatably provided on both sides of the end of the sliding stopper 362. The rotational stoppers 363 are respectively located on both sides of the toes and the heels. When the user's feet are clamped front and back, the rotational stoppers 363 on both sides will wrap the feet left and right, thereby further fixing the feet, so that the user can perform leg training movements such as backward kicking more stably and safely.

[0047] See also Fig.11The adaptive walking module 4 includes a magnetic field base 41 installed in the yielding slot 12, and a slider 42 is slidably arranged on the magnetic field base 41 to achieve displacement in the front-to-back direction, corresponding to the front-to-back misalignment of the left and right feet of the user when walking. One end of a first connecting rod 43 is rotatably connected to the slider 42, and the other end of the first connecting rod 43 is rotatably connected to the second connecting rod 44, and a pedal 45 is fixedly arranged on the second connecting rod 44. One end of the first connecting rod 43 is rotatably connected to the slider 42, and the other end is rotatably connected to the second connecting rod 44. This rotational connection method enables the first connecting rod 43 to swing as the slider 42 slides, thereby driving the second connecting rod 44 and the pedal 45 to swing up and down and forward and backward, corresponding to the up and down swing and forward and backward swing of the left and right feet of the user when walking.

[0048] See also Fig.12 The footrest 45 is designed according to the user's foot contour and walking habits to ensure that the user can obtain the best support and comfort when performing walking exercises. The footrest 45 includes a forefoot support block 453, a sole support block 454 and a heel support block 455. The forefoot support block 453 supports the user's forefoot to adapt to the bending and stretching of the forefoot. The sole support block 454 supports the middle part of the user's sole to keep the foot stable. The heel support block 455 supports the user's heel to adapt to the lifting and falling of the heel. The forefoot support block 453, the sole support block 454 and the heel support block 455 are hinged together in sequence. Through the hinged connection, the forefoot support block 453, the sole support block 454 and the heel support block 455 can rotate relatively, thereby adapting to the bending and stretching of the user's foot in different walking movements.

[0049] The bottom of the front foot support block 453 and the heel support block 455 are rotatably provided with self-adjusting members 452, respectively. The self-adjusting members 452 automatically adjust the angle and position of the pedal 45 according to the user's foot movements. The self-adjusting members 452 are located at the bottom of the front foot support block 453 and the heel support block 455. They can automatically adjust the angle and position of the pedal 45 according to the user's foot movements, thereby ensuring that the pedal 45 always maintains the best contact and support with the user's foot. The bottom of the self-adjusting member 452 is rotatably provided with an insert block 451, which is fixedly provided on the second connecting rod 44. The insert block 451 is fixedly provided on the second connecting rod 44 and is connected to the self-adjusting member 452 by a rotatable setting. In this way, the movement of the second connecting rod 44 can be transmitted to the pedal 45 through the insert block 451 and the self-adjusting member 452, thereby driving the pedal 45 to perform adaptive adjustment.

[0050] A first adjustable telescopic rod 456 is hinged on the front foot support block 453, and an ankle cuff 457 is also hinged on one end of the first adjustable telescopic rod 456. The ankle cuff 457 is used to fix the user's ankle, prevent the foot from sliding or falling off, and provide additional support. One end of the first adjustable telescopic rod 456 is hinged on the front foot support block 453, and the other end is connected to the ankle cuff 457, so that in the process of fixing the user's ankle, the ankle cuff 457 can be rotated outward by the first adjustable telescopic rod 456, so as to give the user more space to put the sole of the foot into the ankle cuff 457, thereby completing the installation of the ankle cuff 457. The length of the first adjustable telescopic rod 456 is automatically adjustable. When the user stands, the length of the first adjustable telescopic rod 456 will change accordingly, and its length will be gradually lengthened or shortened to adapt to the length of the user's instep.

[0051] The second adjustable telescopic rod 458 is hinged on both sides of the sole support block 454, and one end of the second adjustable telescopic rod 458 is detachably mounted on both sides of the ankle cuff 457. The second adjustable telescopic rod 458 is used to fix both sides of the sole to prevent the sole from being laterally sprained, and the second adjustable telescopic rod 458 can also automatically adjust the length. When the user is standing, the second adjustable telescopic rod 458 will automatically adjust to a length that fits the height of the side of the user's sole, thereby better fixing the sole. Both sides of the ankle cuff 457 are provided with protruding fixed columns 4571, which serve as the connection points of the second adjustable telescopic rod 458. One end of the second adjustable telescopic rod 458 is provided with a buckle 4581, which can be buckled on the fixed column 4571. The buckle 4581 is used to connect the second adjustable telescopic rod 458 and the ankle cuff 457, allowing for quick installation and removal.

[0052] A semiconductor sheet is embedded inside the foot support block 454. When the semiconductor sheet moves in the magnetic field generated by the magnetic field base 41, a voltage difference is generated on both sides of the semiconductor sheet. By measuring this voltage difference through the external data processing module 32 and combining it with the known current and magnetic field parameters, the movement position speed of the mechanism can be monitored and measured, thereby realizing the calculation of the walking distance and calorie consumption of the walking mechanism.

[0053] See also Fig.13The auxiliary support module 5 includes a mounting base 51, which is detachably mounted in the mounting hole 14. The mounting base 51 is rotatably connected with a first adjustment rod 52 and a second adjustment rod 53 in sequence. The end of the second adjustment rod 53 is rotatably provided with a support pad 54. The mounting base 51, the first adjustment rod 52 and the support pad 54 are provided with a motor for changing the shape of the support pad 54 to adapt to the deformed bracket 2. The auxiliary support module 5 provides support for the user during fitness, reducing the risk of falling, and the auxiliary support module 5 can change its shape through the motors provided in the mounting base 51, the first adjustment rod 52 and the support pad 54. It can be transformed into different shapes according to the different body positions that the user wants to exercise. If the user needs to exercise the back, it can become a comfortable backrest to give the user just the right support; when the user wants to do some training that requires sitting, it can instantly convert into a seat; when the user needs to relax and rest after training, it can become a recliner to let the user relax his body and mind.

[0054] Working principle: When using the fitness door frame for fitness, the reverse torque function of the brushless motor package 22 and the rotation function of the rotary motor 236 can be used to change the angles between the main support 23 and the exercise platform 1, and between the main support 23 and the slave support 21, so as to achieve the purpose of exercising muscles in different parts. Mode 1: For example Figure 1 , when the main support 23 and the slave support 21 are fixed in a vertical state by the rotating motor 236 and the brushless motor package 22, the electrostatic induction handle 34 is located on the top of the user, and the user can perform pull-ups, hanging leg raises, etc. Mode 2: Control the main support 23 and the slave support 21 to move to Fig.14 When the user is in the position shown, he can do a weighted squat. At this time, the slave bracket 21 is fixedly connected to the brushless motor package 22, and the main bracket 23 is connected to the brushless motor package 22 through the reverse torque capacity of the brushless motor package 22, that is, a certain resistance is generated between the driving gear 222 and the rack 233 through the brushless motor package 22, so that the user feels as if a heavy object is carried on the user's shoulders when squatting. Mode 3: As shown in FIG. Fig.15 , the same principle as mode 2, you can do dumbbell press. Mode 4: Fig.16 , you can do dumbbell curls. Mode 5, such as Fig.17 , you can do sit-and-forward bend. Mode 5: Fig.18 , you can do backward pedaling. At the same time, by installing the auxiliary support module 5, you can unlock more exercise movements. Mode 6, such as Fig.19 , you can do barbell bench press. A total of 20 fitness movements are supported, which can cover 80% of the muscle groups of the human body.

[0055] When the user is exercising, the camera 232 will emit an infrared light matrix to scan the human body, which will be reflected into the structured light receiving end. By recording the speed of each light spot to the receiving end, the distance between the light spot and the camera 232 is recorded, thereby scanning the 3D model of the human body. The AI ​​data processing module 32 will delete the redundant sampling parts of the camera 232 and the repeatedly scanned human body fragments. At the same time, it will reduce the dimension of tens of millions of light spots and continuously merge similar light spots until a rough human body outline is formed. At the same time, the projection module 231 will project the correct movements to help users find the correct feeling of exerting force. During projection, the picture will be synchronized with the user's movements to facilitate self-correction by the user. The human-computer interaction module 31 will display the user's physical condition during exercise so that the user can understand the effect of their exercise in real time. It can also use wifi to upload data to the mobile phone app, making it easier for users to check their physical condition.

[0056] By installing the adaptive walking module 4, the user's lower limb strength can be trained and the user's cardiopulmonary function can be enhanced. The user first needs to fix his or her feet in the footrest 45. When fixed, the fastener 4581 on the second adjustment telescopic rod 458 is disengaged from the fixed columns 4571 on both sides of the ankle hoop 457. At this time, the ankle hoop 457 can be rotated upward by a certain angle. The user passes his or her sole through the ankle hoop 457 so that the ankle hoop 457 reaches the position of his or her ankle. Then the entire sole of the foot steps on the three support blocks, and ensures that each part of the sole of the foot corresponds to the position of the three support blocks. Finally, the fastener 4581 on the second adjustment telescopic rod 458 on the left and right sides is fastened to the fixed columns 4571 on the left and right sides of the ankle hoop 457. At this time, the user's feet will be fixed. Then the user can stand up and start walking slowly. When the user is standing, the footrest 45 will adapt to the contour of the user's foot and wrap it. Specifically, when the user is standing, the body weight is applied to the front foot support block 453, the sole support block 454 and the heel support block 455, and the front foot support block 453, the sole support block 454 and the heel support block 455 will sink downward. At this time, the self-adjusting member 452 located at the bottom of the front foot support block 453 and the heel support block 455 will expand outward until it adapts to the user's foot length. Since the front foot support block 453, the sole support block 454 and the heel support block 455 are hinged together and the sole support block 454 is located in the middle, and the front foot support block 453 and the heel support block 455 are stepped on outward and downward, since there is an arch on the sole of the human foot, the sole support block 454 will fit upward at the arch of the sole of the human foot. While the forefoot support block 453, the sole support block 454 and the heel support block 455 adapt to the sole of the foot, the first adjustment telescopic rod 456 and the second adjustment telescopic rod 458 will also automatically adjust their lengths to adapt to the length of the user's instep and the side of the foot as the user stands. After the user stands completely, the footrest 45 will also automatically fit the user's sole. Through this adaptation, it is ensured that the user can easily achieve the maximum balance during each exercise, making the user's exercise more stable and efficient, and supporting the sole of the foot and dispersing the foot pressure.

[0057] When the user starts walking, the slider 42, the first connecting rod 43, the second connecting rod 44 and the footrest 45 will change their positions accordingly with the movement of the user's feet. The slider 42, the first connecting rod 43 and the second connecting rod 44 are connected to each other through multiple structures, and multiple degrees of freedom are connected in series to form a multiple degree of freedom structure, so as to better adapt to the complex movement trajectory of the user's feet. In the process of the user's walking, the semiconductor slice in the sole support block 454 will drive the magnetic field generated by the cutting magnetic field base 41, and a voltage difference will be generated on both sides of the slice when the semiconductor slice moves in the magnetic field. By measuring this voltage difference and combining the known parameters of the current and magnetic field, the movement position speed of the mechanism can be monitored and measured, thereby realizing the calculation of the walking distance and calorie consumption of the walking mechanism.
