Abstract
Description
Technical Field
[0001] This invention relates to the field of sports equipment, specifically to an intelligent body correction training device for aerobics. Background Technology
[0002] Aerobics is an exercise with aesthetic and artistic qualities. Beginners often need posture correction when learning aerobics. Splits, as one of the commonly used posture correction training exercises in aerobics, can not only improve athletes' flexibility and coordination and increase the difficulty of their movements, but also create beautiful dynamic lines, thereby enhancing the aesthetics of aerobics.
[0003] During the splits, beginners typically need to stretch their ligaments to achieve the maximum possible split angle. However, due to psychological factors such as fear of injury, beginners often resist the splits when attempting to lower themselves, preventing them from reaching the appropriate angle. This results in insufficient stretching and poor posture correction training. Therefore, beginners usually need assistance from coaches or other students to complete the stretching exercises. However, due to the lack of experience of other students, they cannot adjust the lowering height or correct the student's movements according to each individual's physical characteristics, which can easily lead to excessive lowering height. Furthermore, the student performing the splits may not be able to adjust in time when experiencing pain, increasing the risk of strain and affecting subsequent training.
[0004] Therefore, in order to help new trainees overcome psychological pressure when performing splits and stretches alone, achieve the best stretching effect in their legs, and improve the effect of body shape correction, a smart body shape correction training device for aerobics is proposed. Summary of the Invention
[0005] The purpose of this invention is to provide an intelligent body correction training device for aerobics, which can assist novice trainees in completing movements with appropriate force when performing body correction exercises in aerobics. This ensures that no strain injury is caused to the trainees during the stretching process, allowing novice trainees to overcome psychological pressure and achieve the maximum stretching effect in their legs, thereby improving the effectiveness of the correction training.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A body shaping intelligent correction training device for aerobics includes a support frame and a seat cushion mounted on the support frame. A mounting base is slidably mounted on the support frame, and an adjustment plate is connected between the seat cushion and the mounting base. The two ends of the adjustment plate are hinged to the seat cushion and the mounting base, respectively. A protective sleeve is provided on the mounting base, and a tensioning device is provided on the mounting base to control the up-and-down movement of the protective sleeve. A pressure sensor is provided on the protective sleeve to detect the vertical pressure it bears. When the pressure sensor detects that the pressure reaches a set value, it controls the tensioning device to move the protective sleeve downward. An adjustment switch is provided on the support frame to control the start and stop of the tensioning device. The support frame is provided with an adjustment device and a fixing device. The fixing device is used to restrict the mounting base from sliding to the sides away from the seat cushion, and the fixing device releases the restriction on the mounting base when the adjustment device is triggered. The adjustment device can adjust the relative height between the protective sleeve and the seat cushion by the weight of the user, and after the pressure of the user's weight is removed, it drives the seat cushion to return to its original position and drives the mounting base to move via the adjustment plate.
[0008] This stretching device assists beginners in performing splits. While seated on a cushion with feet resting on protective supports, the device allows for controlled up-and-down movement of the supports to facilitate the splits. Pressure sensors control the stretching force, ensuring appropriate intensity to maximize the stretch's effectiveness and prevent injury. This helps beginners overcome psychological pressure and achieve better posture correction. An adjustment mechanism controls the split angle, adapting to different body types to enhance the device's versatility. The adjustment also allows for adjusting the support position, enabling users to adjust the split angle while their feet are on the supports. The system allows beginners to better adjust to a suitable split angle by feeling the stretching force in their feet. The sliding connection of the mounting base, along with the adjustment plate that connects the seat to the mounting base, allows for adjustment of the protective sleeve position, ensuring a constant distance between the sleeve and the seat. This prevents the sleeve from rubbing against the ankles during split angle adjustments, avoiding discomfort for the user. The fixing device allows the mounting base to be fixed to the support when the split angle is not being adjusted. When the adjustment device is activated, the fixing device releases its restriction on the mounting base, allowing for simultaneous adjustment of the sleeve position and split angle. The adjustment switch allows for rapid stopping of the stretching device in case of malfunction, preventing personal injury due to equipment failure.
[0009] Preferably, the stretching device includes a guide cylinder mounted on a mounting base, a power rod slidably mounted inside the guide cylinder, a sheath connected to the power rod via a telescopic cylinder, a spring connecting the sheath and the power rod, with both ends of the spring fixedly connected to the sheath and the power rod respectively, a pressure sensor mounted on the power rod and in contact with the spring, a detection groove on the telescopic cylinder, a detection switch located on the side wall of the detection groove on the power rod, an indicator light electrically connected to the detection switch on the seat, a push block with an inclined surface slidably mounted on the mounting base, the inclined surface cooperating with the power rod, a power component on the mounting base for pushing the push block, a limit switch inside the mounting base for detecting when the power rod has moved to its lowest point, the limit switch, the pressure sensor, and the detection switch all electrically connected to the power component, two handles symmetrically arranged on the bracket, an adjustment switch mounted on the handle, and the adjustment switch electrically connected to the power component.
[0010] The push block moves by a power component, which in turn moves the power rod upwards. The reciprocating movement of the power component moves the power rod up and down. During this process, the user pulls their body downwards with both hands to achieve a split stretch. A pressure sensor is installed at the connection between the power rod and the protective sleeve, and a limit switch is installed on the mounting base. The limit switch and pressure sensor control the maximum and minimum travel of the push block, allowing for adjustments to the split stretch intensity based on individual body conditions, making the equipment highly adaptable. One end of a spring is fixedly connected to the telescopic cylinder and the power rod, respectively. If the foot posture is inaccurate, it will cause the telescopic cylinder to rotate, triggering a detection switch and preventing the power component from starting. An indicator light will illuminate, prompting the user to correct their posture. The user must adjust their split stretch position before performing the stretch, preventing injury to beginners due to incorrect posture. Handles are provided for beginners to use for support when feeling discomfort, allowing them to relax their feet and avoid overstretching that could cause injury.
[0011] Preferably, the adjustment device includes multiple gas springs connected to the seat cushion and the support respectively. The multiple gas springs are symmetrically distributed on both sides of the seat cushion. The gas springs are inclined and their ends are hinged to the support and the seat cushion respectively. Each gas spring is threaded with an electromagnetic pressure relief valve. The seat cushion is snapped with a control switch for controlling the electromagnetic pressure relief valve. The seat cushion and the mounting base are connected together by an adjustment plate. The mounting base is slidably mounted on the support. The electromagnetic pressure relief valve is connected to a fixing device through an air pipe. The fixing device includes multiple locking teeth set on the support. The mounting base is provided with locking pins that cooperate with the locking teeth. The mounting base is provided with a piston with a piston rod inside. The piston rod is connected to the locking pins. The locking pins are elastically connected to the mounting base. An exhaust gap is provided between the piston rod and the mounting base.
[0012] By using multiple gas springs and controlling the solenoid pressure relief valve via a control switch, the seat cushion can be lowered under the user's weight. At this time, the ankles rest on the protective sleeves. The adjusting plate connects to the mounting base, allowing the mounting base to move as the seat cushion lowers, thus adjusting the position of the protective sleeves. This ensures that the distance between the protective sleeves and the seat cushion remains constant during the descent, preventing relative displacement between the sleeves and ankles and avoiding friction during split angle adjustments. The locking pins, with their elastic connection, engage with the locking teeth, allowing the pins and adjusting plate to support the user's weight and preventing leakage and damage from prolonged pressure on the gas springs. When the split angle needs adjustment, the gas inside the gas springs is released, disengaging the locking pins from the locking teeth, allowing for adjustment. The venting gap allows control over the speed of split angle adjustment, preventing excessive stretching that could cause injury if the user cannot react quickly enough.
[0013] Preferably, the upper end of the power rod is provided with a mounting plate, the sheath is slidably mounted on the mounting plate, and springs are connected between the sheath and the mounting plate on both sides.
[0014] By sliding the protective sleeve onto the skateboard, the position of the sleeve can be adjusted by pushing it when people place their ankles on it. This allows the sleeve to be adapted to different leg lengths, improving the device's adaptability and practicality. When the stretching device moves the sleeve, it will have relative displacement with the skateboard, while the foot will not have relative displacement with the sleeve. Therefore, the sleeves will not rub against each other, causing discomfort. The second spring ensures that the sleeve is always pressed to one side, preventing the ankle from moving inside the gaps in the sleeve and causing friction between the sleeve and the ankle, thus improving user comfort.
[0015] Preferably, the sheath is provided with an airbag, the airbag has a groove in the middle, the groove width is set to 7cm, the internal pressure of the airbag is set to 2.7kPa, and the airbag volume is set to 0.34L.
[0016] The protective sleeve is equipped with an airbag. The softness of the airbag improves the comfort of people when placing their feet on it. The width of the airbag groove is set to 7cm, which can ensure that the smallest normal ankle can be fixed in the middle of the ankle. When a foot larger than the width of the airbag groove is fixed in the protective sleeve, the airbag can fix ankles of different sizes. The pressure is set to 2.7kPa and the airbag volume is set to 0.34L. When a normal person's larger ankle is placed, the airbag pressure can still be maintained at a normal value, which can avoid excessive pressure and discomfort to the user.
[0017] Preferably, the maximum height of the push block is set to 15cm, and the inclined surface is an arc-shaped surface with a slope that gradually decreases from bottom to top.
[0018] By adjusting the height of the push block, the stretching range of beginners can be kept within a suitable range, and the overall height of the stretching device can be reduced, thereby reducing the volume of the training device and making it easier to place. The inclined plane is an arc-shaped surface with a slope that gradually decreases from bottom to top, which can gradually reduce the moving speed of the power bar and avoid the situation where people cannot react and cause injury when the angle of the split is large due to excessive speed.
[0019] Preferably, one of the handles is slidably mounted with a height-increasing pad, and the other handle is detachably mounted on the bracket by a snap-fit mechanism. The protective sleeve is L-shaped, and a spring is connected to the height-increasing pad. The spring can push the height-increasing pad away from the ground. The height-increasing pad is internally bolted to a locking block. The handle is provided with multiple slots that cooperate with the locking block. A backing plate is rotatably mounted on the height-increasing pad, and an anti-slip pad is provided below the height-increasing pad.
[0020] The height-increasing pad allows users to sit more comfortably on the ground when performing splits, increasing their height and preventing friction between the L-shaped protective sleeve and the base plate. The backrest prevents movement on the height-increasing pad, eliminating the need for hand support of the lower body and making splits easier. The anti-slip pad prevents wobbling during splits, improving stability and increasing height adjustment. The locking blocks and slots allow users to adjust the height-increasing pad to any position, enhancing adaptability. The spring three allows the height-increasing pad to be lifted off the ground, making it easier to adjust its position.
[0021] Preferably, the bracket has a sliding groove inside, and a limit switch is provided inside the sliding groove. The sliding groove is inclined downward toward the detachable handle side. The limit switch is located at the lowest point of the sliding groove. A ball is provided inside the sliding groove to trigger the limit switch. The limit switch is electrically connected to the detection switch.
[0022] By setting up a slide and a limit switch inside the slide, the movement of the ball triggers the limit switch to control the operation of the detection switch, thereby preventing the posture detection switch from being accidentally triggered when the training device is performing left and right splits, which would cause the device to malfunction.
[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0024] 1. When beginners are practicing splits in aerobics posture correction, a stretching device with a protective sleeve can be installed. By controlling the movement of the sleeve through the stretching device, beginners can assist in performing splits independently. The stretching device can also adjust the stretching intensity according to each beginner's own condition, ensuring that beginners can complete the splits with appropriate force during aerobics posture correction training. This improves the posture correction effect and avoids injuries during training, helping beginners overcome psychological pressure and improve the posture correction effect. In addition, the stretching device can also detect the training posture to prevent physical injury caused by inaccurate posture.
[0025] 2. The adjustable device allows users to adjust the split angle and simultaneously adjust the position of the protective sleeve. This prevents changes in the distance between the sleeve and the seat cushion caused by angle adjustments, thus avoiding friction between the sleeve and the user's ankles and causing discomfort. The sleeve is slidably connected to the stretching device via a mounting plate, preventing relative displacement between the ankle and the sleeve during split stretching and avoiding friction between them, which would also cause discomfort. The adjustable position of the sleeve can accommodate different leg lengths, ensuring that different trainees can place their legs in a suitable position when performing split stretches, thereby improving the adaptability of the training device.
[0026] 3. By adding a height-increasing pad and replacing the protective cover with an L-shaped cover, the training device can be placed vertically, assisting people in training for left and right splits. This increases the functionality and practicality of the training device. The height-increasing pad also features a backrest, allowing users to perform splits simply by sitting on the pad and resting their feet on the protective cover, without needing to exert force from other parts of the body, thus improving the ease of use. Furthermore, the seat cushion's locking mechanism and the slots on the handles allow users to adjust the angle of the splits, thereby enhancing the adaptability of the training device.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
[0037] like Figures 1 to 6 The image shows Embodiment 1 of the present invention, which is used for performing front and back splits. The specific solution is as follows:
[0038] The device includes a support frame 1 and a seat cushion 101 mounted on the support frame 1. An adjustment device 3 is connected to the seat cushion 101. The adjustment device 3 includes multiple gas springs 301 hinged to the support frame 1, symmetrically distributed on both sides of the seat cushion 101. A tensioning device 2 is also provided on the support frame 1. The tensioning device 2 includes a mounting base 202 mounted on the support frame 1, and a guide cylinder 203 is provided on the mounting base 202. A power rod 204 is slidably mounted inside the guide cylinder 203, and a protective sleeve 201 is connected to the power rod 204. In use, the support frame 1 is laid flat, and a person sits on the seat cushion 101 with their ankles resting on the protective sleeve 201. The protective sleeve 201 is slidably mounted on the power rod 204 via a mounting plate 4. The extension or retraction of the legs moves the protective sleeve 201 on the mounting plate 4, allowing the position of the protective sleeve 201 to be adjusted according to different people's leg lengths. This allows the training device to be adjusted according to each person's leg length, improving performance. The training device is adaptable and easy to adjust. The protective sleeve 201 is equipped with an airbag 6, which can increase the comfort when the ankle is placed on the protective sleeve 201. The airbag 6 has a groove 601 to facilitate ankle placement. The ankle width of a normal person is 7-12cm. Therefore, the minimum width of the groove 601 is set at 7cm. The airbag 6 is usually used to fix the body part. The pressure of the airbag 6 is generally set at 2.7KPa-4KPa without causing discomfort to the human body. Therefore, the initial pressure of the airbag 6 is set at 2.7KPa. When an ankle larger than 7cm is placed in the airbag 6, in order to avoid discomfort to the human ankle, the pressure of the airbag 6 will not exceed 4KPa after being compressed. The airbag 6 is generally made of leather. The airbag 6 has a combination of cylindrical and rectangular shapes. The diameter and width of the cylindrical and rectangular parts are Dcm and Wcm, respectively. The indentation depth of the airbag 6 is Hcm and the thickness is Tcm.
[0039] To ensure that the pressure of the airbag 6 after compression is less than 4.0 kPa, we can calculate the minimum volume based on the ideal gas law (PV = nRT) and simple geometric formulas. When the gas volume decreases, its pressure and temperature increase inversely.
[0040] Assuming the gas temperature and molar mass inside airbag 6 remain constant, the minimum volume of airbag 6 can be calculated using the following formula:
[0041] V = (P1V1T2) / (P2T1)
[0042] Wherein, P1 is the initial pressure of airbag 6, V1 is the initial volume of airbag 6, T1 is the initial temperature of the gas (assuming room temperature, approximately 300K), T2 is the final temperature of the gas after compression (assuming it is still room temperature), and P2 is the final pressure of airbag 6 (i.e., 4.0kPa).
[0043] Since the length and width of the recess 601 are 7cm, it allows for an ankle 7cm wide to be inserted. When an ankle 12cm wide is inserted into the recess 601, the maximum diameter of the airbag 6 must be greater than 12cm. Therefore, we can assume that the bottom of the airbag 6 is circular with a diameter of 12cm. Thus, the following calculation formula can be derived:
[0044] V=(2.7kPa×πr 2 ×(H+W)×T×300K) / (4.0kPa×πr 2 ×D×T×300K)
[0045] Where r = 6cm is the bottom radius of airbag 6, H = 15cm, W = 7cm, D = 12cm - 7cm = 5cm, and T is the wall thickness of airbag 6.
[0046] Simplifying the above equation, we get:
[0047] V = (2.7 / 4.0)((H+W) / D)π 2
[0048] Substituting the parameters in the above formula, we can obtain the minimum volume as:
[0049] V≈0.34L
[0050] Therefore, during the design process, if the volume of airbag 6 reaches or exceeds 0.34L, it can be ensured that when a 12cm wide ankle is placed in the groove 601, the pressure inside airbag 6 is less than 4.0kPa, so as to ensure that airbag 6 will not cause discomfort to people. Therefore, the overall volume of airbag 6 is set to 0.34L, which can reduce the cost of airbag 6 and avoid discomfort to the human body caused by excessive pressure from airbag 6.
[0051] After placing your feet on the protective sleeve 201, press the control switch 303 on the handle 212 to control the electromagnetic pressure relief valve 302 to release air. At this time, the gas support 301 begins to release air, and the gas inside the gas support 301 pushes the piston 507. At this time, the locking pin 506 disengages from the locking tooth 505, and the fixing device 5 releases its restriction on the mounting base 202. The height of the seat cushion 101 can then be lowered, and the two mounting bases 202 move to both sides of the bracket 1, increasing the split angle. During the adjustment process, the movement of the mounting bases 202... The protective sleeve 201 can be moved simultaneously, thus avoiding the reduction in the relative position of the protective sleeve 201 and the seat cushion 101 due to the increase in the split angle. This increases the adjustment range of the protective sleeve 201 position and reduces the sliding distance of the protective sleeve 201 on the mounting plate 4, thereby reducing the length of the mounting plate 4. This avoids the problem that the mounting plate 4 will generate a large lever effect due to its excessive length, which would cause the pressure sensor 207 to be subjected to large pressure on one side and be easily damaged. When the stop control switch 303 is started, the gas support 301 stops deflation.
[0052] After the user has adjusted the split angle, if the legs are tilted, the split angle will be incorrect, potentially causing injury during the split stretch. Therefore, when the legs are tilted, the feet will rotate the telescopic cylinder 205, triggering the detection switch 209. At this time, the control indicator light of the detection switch 209 will illuminate, and the power component 211 will not start, prompting the user to adjust their posture. After adjustment, the telescopic cylinder 205 will automatically reset under the torque of the spring 206, releasing the control of the detection switch 209. To prevent excessive rotation of the telescopic cylinder 205 from damaging the detection switch 209, the detection switch 209 is a push-button type. The switch allows the detection switch 209 to be pressed and embedded in the power rod 204. When the power component 211 pushes the push block 210 to move, it causes the power rod 204 to move up and down, thereby causing the sheath 201 to move up and down, thus stretching the user in a split position. During the movement of the push block 210, when the pressure sensor 207 reaches the set value due to the elastic force of the spring 206, it will cause the push block 210 to move in a certain direction. When the power rod 204 moves to the lowest point of the push block 210, the limit switch 213 controls the power component 211 to move in the opposite direction, so that the push block 210 moves back and forth and the stretching force is controlled, thereby achieving different forces for different people. The splits stretching exercise is performed using a power unit 211, which can be an electric cylinder or an electric push rod. In the training room, an electric power unit 211 is preferred. A normal beginner's single split angle is 10°, while some beginners with better physical fitness can reach 20°. Therefore, the average person can only press down to a height of 15cm. Thus, the maximum height of the push block 210 is set at 15cm, and the inclined plane 2101 is an arc-shaped surface with a gradually decreasing slope from bottom to top. This allows the moving speed of the power rod 204 to gradually decrease, preventing injuries caused by excessive speed when the split angle is large, which could lead to insufficient reaction time. During the splits stretching process, the protective sleeve 201... Sliding on the mounting plate 4, the protective sleeve 201 remains stationary relative to the ankle, thus preventing friction between the ankle and the sleeve 201 that could cause discomfort. A spring 14 connects the sleeve 201 and the mounting plate 4, ensuring that the sleeve 201's pushing force on the ankle is always directed to one side, preventing the ankle from moving within the gaps in the sleeve 201 and rubbing against it, which could also cause discomfort. If a new trainee feels discomfort, they can quickly press the adjustment switch 15 on the handle 212 to stop the stretching device 2, thus preventing overstretching and leg strain caused by equipment malfunctions or other special circumstances that prevent the stretching device 2 from descending.After excessive adjustment of the split angle, lift your body using the hand support handle 212. The seat 101 will then return to its original position under the action of the gas spring 301. This allows the mounting base 202 to be pulled via the adjustment plate 304. The locking teeth 505 have an inclined surface facing the seat 101, ensuring they do not obstruct the movement of the locking pin 506, thus allowing them to return to their original position along with the seat 101. This method is simple to operate and facilitates easier adjustment of the split angle.
[0053] like Figures 1 to 7 As shown, this is Embodiment 2 of the present invention, which is used for performing left and right splits. The specific solution is as follows:
[0054] When performing a split, the legs need to open to the sides. Therefore, the support 1 must be placed vertically during use. A heightening pad 7 is slidably installed on one side of the handle 212, and the other side's handle 212 is connected to the support 1 via a snap-fit. To use, pull out the bottom heightening pad 7 and remove the top handle 212. The protective cover 201 then needs to be replaced with an L-shaped cover 201. The user simply sits on the heightening pad 7 and places both feet on the L-shaped cover 201. The backrest 9 is hinged to the heightening pad 7. To use, the backrest 9 is flipped up. Stand up and lean your back against the backrest 9. If the split angle is not suitable, use the hand support 1 to lift your body. At this time, the height-increasing pad 7 will lift off the ground under the action of spring 38. You can then use your buttocks to push the seat cushion 101 to adjust the split angle. Once you feel that the split angle is suitable, sit on the height-increasing pad 7. At this time, the locking block 701 and the locking slot 2121 will cooperate to prevent the training device from moving. After the angle is adjusted, press the control switch 303. Then you can use the stretching device 2 to spread your legs and perform a split stretch. The height of the seat cushion 101 needs to be adjusted to the lowest position to avoid interfering with the user's adjustment of the split angle. In this embodiment, the stretching device 2 and the adjustment device 3 are the same as in embodiment one, and will not be described in detail here. However, since there is a built-in posture detection switch 209, and because the horizontality of the legs will deviate slightly when performing left and right splits, the telescopic cylinder 205 will be twisted, triggering the detection switch 209, which will cause the training device to malfunction. Therefore, an inclined slide groove 11 is provided inside the bracket 1, and a ball bearing 13 is also provided inside the slide groove 11. When the bracket 1 is laid flat, the ball bearing 13 contacts the limiting switch 12, and the detection switch 209 is performing detection. When the bracket 1 is placed vertically, the ball bearing 13 disengages from the limiting switch 12 under the action of gravity, and the detection switch 209 is in the closed state and cannot play a position adjustment role. The heightening pad 7 is provided with an anti-slip pad 10 to increase the contact area with the ground. The anti-slip pad 10 can also increase the height of the legs from the ground, thereby increasing the distance between the L-shaped protective sleeve 201 and the floor and preventing the L-shaped protective sleeve 201 from rubbing against the base plate.
[0055] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
