Description

Technical Field

[0001] The present invention relates to the technical field of intelligent gymnastics equipment in the fields of sports health and sports training science, and in particular to an intelligent multi-dimensional stretching gymnastics flexibility training device. Background Art

[0002] In the field of sports health and sports training science, gymnastics flexibility training has always received widespread attention and research as an important means to improve physical functions, prevent sports injuries and enhance sports performance; traditional gymnastics flexibility training methods mostly rely on the guidance of coaches or the use of fixed-structure training equipment. These methods and equipment often have limitations such as single function, poor flexibility and difficulty in personalized adaptation; specifically, traditional stretching training equipment lacks sufficient consideration of the body shape, height and training needs of different users in its design, resulting in difficulty in achieving ideal training results during training, and may even increase the risk of injury due to equipment incompatibility.

[0003] In recent years, with the rapid development of intelligent technology, its application in the field of sports training has become increasingly extensive; however, existing intelligent gymnastics training equipment mostly focuses on single-dimensional training adjustments, such as only being able to achieve simple adjustments in height or angle, and the adjustment process mostly relies on manual operation, which cannot achieve truly multi-dimensional, automated and personalized training; in addition, these devices also have shortcomings in safety monitoring, lacking real-time monitoring and early warning mechanisms for key parameters during training, making it difficult to effectively ensure user safety.

[0004] In response to the above problems, the project team began to explore the combination of intelligent control technology, sensor technology and multi-dimensional adjustment mechanism to develop a new type of intelligent multi-dimensional stretching gymnastics flexibility training device; the device aims to automatically adjust the height, angle and other parameters of the training equipment according to the individual differences of the user through an intelligent adjustment system to achieve a personalized training experience; at the same time, it integrates advanced safety monitoring modules to monitor key parameters during training in real time to ensure the safety and effectiveness of user training; this research direction not only conforms to the current development trend in the field of sports health and sports training science, but also provides a new solution for improving the effectiveness and safety of gymnastics flexibility training. Summary of the Invention

[0005] The purpose of the present invention is to provide an intelligent multi-dimensional stretching gymnastics flexibility training device, which integrates intelligent control technology, sensor monitoring technology and multi-dimensional mechanical adjustment mechanism, aiming to provide an efficient, safe and personalized solution for gymnastics flexibility training, and is suitable for multiple scenarios such as teaching in sports colleges, training of professional athletes and public fitness.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: an intelligent multi-dimensional stretching gymnastics flexibility training device, comprising a fixed support assembly and a movable support assembly; the fixed support assembly comprises a base crossbar, a base longitudinal bar welded to one end of the base crossbar, an L-shaped support vertical bar welded to the other end of the base crossbar, and an inclined arch bridge-shaped support bar welded between the top surface of the base crossbar and the back surface of the L-shaped support vertical bar;

[0007] The movable bracket assembly includes a support beam hinged to the top of an L-shaped support post via a pin, a U-shaped limit rod hinged to the free end of the support beam, and an articulated support column hinged to the bottom end of the L-shaped support post. An inverted U-shaped hinge plate is welded to the bottom end of the articulated support column, which is hinged to the bottom end of the L-shaped support post via a pin. An extension column is longitudinally inserted into the top end of the articulated support column, allowing for longitudinal adjustment of height and locking and limiting movement via a locking rod. The end of the support beam closest to the first support plate is hinged to the first support plate via a U-shaped hinge rod. Furthermore, the assembly includes an intelligent adjustment module and a safety management module.

[0008] Intelligent adjustment module: includes an electric push rod installed inside the extension column, a control unit connected to the electric push rod, and a user interface. The control unit automatically adjusts the height of the extension column according to parameters input by the user interface to accommodate users of different heights.

[0009] Safety management module: includes a position sensor, which is used to monitor whether the limit card shaft end is correctly engaged between two adjacent blocks. When the position sensor detects that the limit card shaft end has slipped from between the two blocks or is not correctly engaged, it sends a signal to the control unit. The control unit immediately issues an emergency warning signal through the user interface and recommends that the user stop using the device until the problem is resolved.

[0010] This solution is preferred, in which a limiting clamping shaft end is provided at one end of the U-shaped limiting clamping rod away from the supporting top beam, and the limiting clamping shaft end is clamped between multiple blocks fixed at equal distances on the outer wall of the inclined arch bridge-shaped bracket rod to form a support limit for the inclination of the U-shaped limiting clamping rod.

[0011] This solution is preferred, wherein the first support plate and the second support plate are respectively used to carry personnel to adjust different training postures. When the person sits on the first support plate, the second support plate is moved upward so that the limit clamping shaft end moves to the desired position on the inclined arch bridge-shaped bracket rod and is clamped between two adjacent blocks to achieve angle adjustment.

[0012] In a preferred embodiment of the present invention, a first support plate is hingedly connected to the top end of the extension column, allowing the height to be adjusted according to user needs and the position to be locked by a locking rod.

[0013] This solution is preferred, wherein the inclined arch bridge-shaped support rod has a plurality of blocks installed at equal distances on its outer wall, and these blocks are used in conjunction with the limiting clamping shaft end to adjust and fix the angle of the second support plate.

[0014] This solution is preferred, wherein the second support plate is moved downward so that its limit axis end is clamped between two adjacent stoppers at the bottom of the inclined arch bridge-shaped bracket rod, and the second support plate is adjusted to a horizontal state for the user to lie down and use.

[0015] This solution is preferred, in which the electric push rod in the intelligent adjustment module can accurately adjust the height of the extension column according to the user input parameters received by the control unit to meet the needs of users of different heights.

[0016] This solution is preferred, in which the position sensor of the safety management module is installed on the inclined arch-shaped bracket rod to monitor the status of the limit card shaft end in real time. Once the limit card shaft end is found to have slipped from between the two blocks or is not correctly engaged, the control unit is immediately triggered to send an emergency warning signal.

[0017] This solution is preferred, wherein the angle sensor and feedback mechanism include an angle sensor arranged between the support top beam and the U-shaped limit rod, which is used to monitor the angle changes of the second support plate in real time; when the angle changes, the angle sensor transmits data to the control unit, and the control unit makes a judgment based on the preset safety angle range. If it exceeds the safety range, a warning signal is sent to the user through the user interface, and the control unit automatically adjusts to a safe angle.

[0018] This solution is preferred, in which the user interface is not only used to receive parameters input by the user, but also serves as a display platform for system feedback information, displaying the current device status, safety tips and adjustment suggestions, ensuring that the user can understand the device operation status in a timely manner and take corresponding measures.

[0019] Compared with the prior art, the technical effects and advantages of the present invention are:

[0020] This intelligent multi-dimensional stretching gymnastics flexibility training device allows users to input personal height information or select a preset configuration through the user interface. The control unit receives the data and commands the electric push rod to accurately adjust the height of the extension column. The locking rod ensures stability after the height adjustment. The module can automatically adjust the height of the first support plate according to the height of each user, so that users of different heights can get the best user experience. There is no need for manual adjustment or reliance on fixed height settings. Height adjustment can be completed through simple user interface interaction, which greatly simplifies the operation process and improves the convenience and efficiency of use. The precise control of the electric push rod ensures that the height of each adjustment meets user needs and avoids the errors that may occur in traditional manual adjustment.

[0021] The position sensor continuously monitors whether the shaft end of the limit card is correctly engaged between the two adjacent blocks. When it detects that the shaft end of the limit card has slipped or is not correctly engaged, it immediately sends a signal to the control unit. The control unit sends an emergency warning signal through the user interface and recommends that the user stop using it until the problem is resolved. Through real-time monitoring by the position sensor, any situation that may cause safety hazards can be discovered in time, such as the accidental slipping of the shaft end of the limit card. Once an abnormal situation occurs, the system will immediately issue a warning to remind the user to pay attention to safety and avoid the risk of injury caused by equipment failure. This proactive safety management mechanism greatly improves the overall safety of the equipment, allowing users to feel more at ease during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without one or more of these details. In other instances, certain technical features well known in the art are not described to avoid confusion with the present invention.

[0029] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0030] Example 1:

[0031] This embodiment provides Figures 1 to 3 The device is an intelligent multi-dimensional stretching gymnastics flexibility training device, comprising a fixed support assembly and a movable support assembly; the fixed support assembly comprises a base crossbar 4, a base longitudinal bar 9 welded to one end of the base crossbar 4, an L-shaped support vertical bar 5 welded to the other end of the base crossbar 4, and an inclined arch-bridge-shaped support bar 10 welded between the top surface of the base crossbar 4 and the back surface of the L-shaped support vertical bar 5;

[0032] The movable bracket assembly includes a support beam 14 hinged to the top of the L-shaped support post 5 via a pin, a U-shaped limiter rod 12 hinged to the free end of the support beam 14, and a hinged support post 6 hinged to the bottom of the L-shaped support post 5. An inverted U-shaped hinge plate 7 is welded to the bottom of the hinged support post 6, which is hinged to the bottom of the L-shaped support post 5 via a pin. An extension column 15 is longitudinally inserted into the top of the hinged support post 6, allowing for longitudinal adjustment of height and locking and limiting movement via a locking rod 8. The end of the support beam 14 closest to the first support plate 2 is hinged to the first support plate 2 via a U-shaped hinge rod 16. Furthermore, the assembly includes an intelligent adjustment module and a safety management module.

[0033] Intelligent adjustment module: includes an electric push rod installed inside the extension column 15, a control unit connected to the electric push rod, and a user interface. The control unit automatically adjusts the height of the extension column 15 according to the parameters input by the user interface to adapt to users of different heights.

[0034] Safety management module: includes a position sensor for monitoring whether the limit card shaft end 13 is correctly engaged between two adjacent blocks 11. When the position sensor detects that the limit card shaft end 13 has slipped from between the two blocks 11 or is not correctly engaged, it sends a signal to the control unit. The control unit immediately sends an emergency warning signal through the user interface and recommends that the user stop using it until the problem is resolved.

[0035] In this embodiment, a limiting clamping shaft end 13 is provided at one end of the U-shaped limiting clamping rod 12 away from the supporting top beam 14. The limiting clamping shaft end 13 is clamped between multiple stop blocks 11 fixed at equal distances on the outer wall of the inclined arch-shaped bracket rod 10, forming a support limit for the inclination of the U-shaped limiting clamping rod 12.

[0036] In this embodiment, the first support plate 2 and the second support plate 3 are respectively used to carry people to adjust different training postures. When the person sits on the first support plate 2, the second support plate 3 is moved upward so that the limit clamping shaft end 13 moves to the desired position on the inclined arch bridge-shaped support rod 10 and is clamped between two adjacent blocks 11 to achieve angle adjustment.

[0037] In this embodiment, the top end of the extension column 15 is hinged with the first support plate 2 , allowing the height to be adjusted according to user needs, and the position is locked by the locking rod 8 .

[0038] In this embodiment, a plurality of stoppers 11 are installed at equal distances on the outer wall of the inclined arch bridge-shaped support rod 10 . These stoppers 11 are used in conjunction with the limiting clamping shaft ends 13 to adjust and fix the angle of the second support plate 3 .

[0039] In this embodiment, the second support plate 3 is moved downward so that its limit axis end 13 is clamped between two adjacent stoppers 11 at the bottom of the inclined arch bridge-shaped bracket rod 10, and the second support plate 3 is adjusted to a horizontal state for the user to lie down and use.

[0040] In this embodiment, the electric push rod in the intelligent adjustment module can accurately adjust the height of the extension column 15 according to the user input parameters received by the control unit to meet the needs of users of different heights.

[0041] In this embodiment, the position sensor of the safety management module is installed on the inclined arch-shaped support rod 10 to monitor the status of the limit card shaft end 13 in real time. Once the limit card shaft end 13 is found to have slipped from between the two blocks 11 or is not properly engaged, the control unit is immediately triggered to send an emergency warning signal.

[0042] In this embodiment, the angle sensor and feedback mechanism include an angle sensor arranged between the support top beam 14 and the U-shaped limit rod 12, which is used to monitor the angle changes of the second support plate 3 in real time; when the angle changes, the angle sensor transmits data to the control unit, and the control unit makes a judgment based on the preset safety angle range. If it exceeds the safety range, a warning signal is sent to the user through the user interface, and it is automatically adjusted to a safe angle.

[0043] In this embodiment, the user interface is not only used to receive parameters input by the user, but also serves as a display platform for system feedback information, displaying the current device status, safety tips and adjustment suggestions, ensuring that the user can understand the device operating status in a timely manner and take corresponding measures.

[0044] Working principle:

[0045] In this intelligent multi-dimensional stretching gymnastics flexibility training device, the user initializes the intelligent adjustment module through the user interface and inputs basic information of personal height and weight. The system automatically detects the status of each component, including the position of the electric push rod, the locking status of the locking rod 8, the working status of the position sensor, etc. The user enters the desired height value or selects a preset configuration on the user interface according to his or her needs. After receiving the data input by the user, the control unit commands the electric push rod inside the extension column 15 to perform a telescopic action to accurately adjust the height of the first support plate 2.

[0046] When the set height is reached, the locking rod 8 is inserted into the corresponding hole to fix the relative position between the extension column 15 and the hinge support 6.

[0047] The user sits on the first support plate 2 and decides whether to adjust the angle of the second support plate 3 to suit different training needs. By moving the second support plate 3 upward, the limit card shaft end 13 slides along the outer wall of the inclined arch-shaped support rod 10 until it finds the appropriate stopper 11 position. The limit card shaft end 13 is then locked between two adjacent stoppers 11, completing the inclination support and position control of the U-shaped limit card rod 12. At this time, the angle sensor monitors and records the current angle.

[0048] The position sensor continuously monitors whether the limit card shaft end 13 is correctly engaged between the blocks 11. If any abnormality is detected, such as the limit card shaft end 13 slipping from between the two blocks 11, a signal is immediately sent to the control unit. Once an abnormality is detected, the control unit sends an emergency warning signal through the user interface and recommends that the user stop using the device until the problem is resolved. During training, the angle sensor continuously monitors the angle changes of the second support plate 3. Whenever the angle changes, the angle sensor transmits data to the control unit, and the control unit makes a judgment based on the preset safety angle range. If it exceeds the safety range, the system will send a warning signal to the user through the user interface and try to automatically adjust to a safe angle.

[0049] After the training, the user can move the second support plate 3 downward so that the limit card shaft end 13 is engaged between the two adjacent blocks 11 at the bottom of the inclined arch-shaped bracket rod 10, and adjust the second support plate 3 to a horizontal state. The user can again command the electric push rod through the user interface to adjust the extension column 15 back to the initial height, preparing for the next use. Finally, close the user interface to end the training.

[0050] Example 2:

[0051] The following is combined with Figure 1-3 , and based on Example 1, a specific example of applying the present invention to a physical education college of a university is described in detail.

[0052] Overall structure of the device: The intelligent multi-dimensional stretching gymnastics flexibility training device 1 of this embodiment mainly includes a fixed bracket assembly, a movable bracket assembly, an intelligent adjustment module, a safety management module, and an angle sensor and feedback mechanism.

[0053] Fixed Bracket Assembly: This embodiment's fixed bracket assembly includes a base crossbar 4, a base longitudinal bar 9 welded to one end of the base crossbar 4, an L-shaped support upright 5 welded to the other end of the base crossbar 4, and an inclined arch-bridge-shaped support rod 10 welded between the top surface of the base crossbar 4 and the back surface of the L-shaped support upright 5. The base crossbar 4, base longitudinal bar 9, and L-shaped support upright 5 together form the device's stable support structure, and the inclined arch-bridge-shaped support rod 10 provides a support foundation for subsequent angle adjustment.

[0054] Movable Bracket Assembly: The movable bracket assembly of this embodiment includes a support beam 14 hinged to the top of the L-shaped support post 5 via a pin, a U-shaped limiter 12 hinged to the free end of the support beam 14, and an articulated support post 6 hinged to the bottom of the L-shaped support post 5. An inverted U-shaped hinge plate 7 is welded to the bottom end of the articulated support post 6. This U-shaped hinge plate 7 is hinged to the bottom end of the L-shaped support post 5 via a pin, allowing the articulated support post 6 to rotate a certain angle relative to the L-shaped support post 5.

[0055] In this embodiment, an extension post 15 is longitudinally inserted at the top end of the hinged support 6. The height of the two is adjusted by longitudinal extension and contraction, and the locking rod 8 is inserted and locked to limit the position, thereby achieving precise adjustment of the height of the first support plate 2. The end of the support top beam 14 closest to the first support plate 2 is hinged to the first support plate 2 via a U-shaped hinge rod 16, allowing the first support plate 2 to rotate relative to the support top beam 14 to a certain angle to accommodate different training postures.

[0056] In this embodiment, a limit clamping shaft end 13 is provided at one end of the U-shaped limit clamping rod 12, away from the support top beam 14. This limit clamping shaft end 13 engages between a plurality of equally spaced stoppers 11 fixed on the outer wall of the inclined arch-shaped support rod 10, thereby supporting and limiting the inclination of the U-shaped limit clamping rod 12. By moving the engagement position of the limit clamping shaft end 13 between different stoppers 11, the angle of the second support plate 3 can be precisely adjusted.

[0057] Intelligent Adjustment Module: In this embodiment, the intelligent adjustment module includes an electric actuator mounted within the extension column 15. The actuator serves as a power source integrated within the extension column, and a control unit connected to the actuator. The control unit is integrated within the device's control system and user interface (not shown in the figure), but can be understood as an operation panel with a display and input buttons. The control unit automatically adjusts the extension and retraction of the actuator based on user interface input parameters such as height, weight, and desired training angle, thereby precisely adjusting the height of the extension column 15 to accommodate users of varying heights.

[0058] Safety Management Module: In this embodiment, the safety management module includes a position sensor, mounted on the inclined arch-shaped support rod near the end of the stopper shaft. This sensor monitors in real time whether the stopper shaft end 13 is properly engaged between two adjacent blocks 11. If the position sensor detects that the stopper shaft end 13 has slipped from between two blocks 11 or is not properly engaged, it immediately sends a signal to the control unit. Upon receiving the signal, the control unit immediately issues an emergency warning signal (such as an audible alarm or flashing lights) through the user interface, and advises the user to stop using the device until the problem is resolved.

[0059] Angle sensor and feedback mechanism: In order to further improve the safety and effectiveness of training, this embodiment also adds an angle sensor and feedback mechanism. The angle sensor is installed between the support beam and the U-shaped limit rod to monitor the angle changes of the second support plate 3 in real time. When the angle changes, the angle sensor transmits data to the control unit. The control unit makes a judgment based on the preset safety angle range. If it exceeds the safety range, it will send a warning signal such as text prompts, sound prompts, etc. to the user through the user interface, and try to automatically adjust the extension and retraction of the electric push rod to adjust the second support plate 3 to a safe angle.

[0060] When using this device, students first enter basic information such as their height and weight through the user interface and select the desired training angle or configuration. Upon receiving the user's input, the control unit instructs the electric actuator to extend and retract, precisely adjusting the height of the first support plate 2 to the desired position, and then locks the position using the locking rod 8.

[0061] The user sits on the first support plate 2 and adjusts the angle of the second support plate 3 as needed. By moving the second support plate 3 upward or downward, the stopper shaft end 13 slides along the outer wall of the inclined arch-shaped support rod 10 until it finds the appropriate position and engages with the stopper 11. At this point, the angle sensor monitors and records the current angle and continuously monitors angle changes.

[0062] During training, the position sensor and angle sensor monitor the engagement status of the stopper shaft end 13 and the angle change of the second support plate 3 in real time. If any abnormality is detected, such as the stopper shaft end slipping or the angle exceeding the safe range, a signal is immediately sent to the control unit. Upon receiving the signal, the control unit immediately issues an emergency warning signal or a warning signal through the user interface and takes appropriate measures, including stopping the electric actuator and advising the user to stop using it, to ensure user safety.

[0063] After the training is finished, the user can use the user interface to instruct the electric push rod to adjust the extension column 15 back to the initial height and adjust the second support plate 3 to a horizontal state for storage or next use. Finally, close the user interface to end the training.

[0064] The intelligent multi-dimensional stretching gymnastics flexibility training device of this embodiment provides users with an efficient, safe and personalized gymnastics flexibility training solution through an intelligent adjustment system and an advanced safety monitoring mechanism.
