[0050] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0051] It should be noted that like reference numerals denote like items in the following drawings, and therefore, once an item is defined in one drawing, it will not be further defined or explained in the subsequent drawings.

[0052] like Figure 1 and Figure 2 As shown, a Hall sensor-based tensioning device 100 helps users effectively exercise by accurately measuring and displaying the tension applied by the user. The tensioning device 100 includes a first end 101, an elastic body 103, and a second end 102; the elastic body 103 is connected between the first end 101 and the second end 102.

[0053] The first end 101 can be designed as a handheld or foot-operated device to accommodate different exercise needs. In diverse environments, users can choose a usage method based on their preferences and exercise goals. While the illustration only shows a foot-operated device, those skilled in the art, after understanding the specific embodiments, can design the first end as a handheld device as needed, thereby forming a two-handed gripping training device with the second end.

[0054] The elastic body 103 is a key component connecting the first end 101 and the second end 102. It is typically made of a highly elastic material, such as rubber or thermoplastic elastomer, to ensure its performance during repeated stretching and compression. The design of the elastic body 103 must ensure sufficient elasticity to accommodate varying tension requirements while also ensuring that it retains its shape and elasticity after extended use, providing a consistent workout experience.

[0055] like Figures 3 to 8As shown, the second end 102 integrates more functional components. It includes a base 10, a handheld portion 20, and a display screen 30. The handheld portion 20 and display screen 30 are mounted on the base 10. The base 10 is the core technical area of ​​the tensioning device 100, housing a circuit board 12, a Hall effect sensor 13, and an articulating joint 14. These components work together to accurately measure and display tension. The handheld portion 20 provides a comfortable grip for the user, while the display screen 30 intuitively displays the user's tension data, allowing the user to monitor their exercise progress in real time.

[0056] The base 10 includes a housing 11, which not only provides physical protection but also serves as a mounting base for the internal components. Inside the housing 11, a circuit board 12, a Hall effect sensor 13, and an articulating joint 14 are strategically arranged to ensure that all components can operate efficiently, independently, and stably.

[0057] The circuit board 12 is connected to the display screen 30. As one of the core components within the housing 11, it carries the control logic and signal processing for the tensioning device. Preferably, the circuit board 12 integrates a microcontroller, signal amplification circuitry, data processing circuitry, and an interface for communicating with the Hall effect sensor 13. These circuits work together to convert the magnetic signals detected by the Hall effect sensor into electronic counts, which are then displayed on the display screen 30.

[0058] In addition, the movable connection part 14 is a key mechanical component in the tensioning device 100, which is responsible for converting the force applied by the user into a measurable displacement. The movable connection part 14 can move up and down in the shell 11. A spring 15 with an upward force is arranged on the movable connection part 14, and the lower end of the movable connection part 14 is connected to the elastomer 103. The spring 15 provides an upward restoring force, which ensures that the movable connection part 14 can quickly and accurately return to its initial position after the elastomer 103 is relaxed. The elastic coefficient of the spring 15, the fatigue life of the material, and the stability in different use environments are all matched with the actual use requirements of the tensioning device and the elastic force of the elastomer 103. The presence of the spring 15 can improve the operating efficiency of the tensioning device and reduce errors in the measurement process.

[0059] Furthermore, the Hall effect sensor 13 includes a Hall effect element 15 disposed on the circuit board 12 and a magnet 16 mounted at the front end of the movable connector 14. Magnet 16 is mounted at the front end of the movable connector 14. As the movable connector 14 moves up and down within the housing 11, magnet 16 moves closer to or further away from the Hall effect element 15. This movement causes the magnetic field strength detected by the Hall effect element to change, generating corresponding electrical signals. These electrical signals are then processed by the circuit board 12 and converted into counting information, which is ultimately displayed on the display screen 30.

[0060] In actual use, the lower end of the movable connection 14 is connected to the elastic body 103. This connection allows the elastic body 103 to transmit force to the movable connection 14 when stretched, thereby driving it downward within the housing 11. When the elastic body 103 relaxes, the movable connection 14 moves upward under the action of the spring 15. This movement triggers the interaction between the magnet 16 and the Hall element 15 of the Hall sensor 13. The magnet 16 is sensed by the Hall element 15 on the circuit board 12, and the number of times is counted, which is displayed on the display 30.

[0061] More specifically, if Figures 3 to 8 As shown, the movable connection part 14 includes a frame-type body a having an inner cavity a1. The inner cavity a1 allows other components such as the spring 15 and the boss v to operate inside it. The upper end of the frame-type body a is provided with a column a2, and the lower end of the frame-type body a is provided with an annular connection part a3 to facilitate connection with the elastic body 103. A magnet 16 is installed at the front end of the column a2. In this embodiment, when the tensioning device 100 is pulled open, the elastic body 103 pulls the movable connection part 14 downward in the housing 11. The magnet 16 at the front end of the column a2 moves away from the Hall element 15, generating a change in the magnetic field. The Hall element 15 can sense this change and convert it into an electrical signal. By detecting the change in this electrical signal, counting is completed and displayed on the display screen. After relaxation, the spring 15 drives the movable connection part 14 to move upward, so that the magnet at the front end of the column a2 is reset.

[0062] The movable connection portion 14 can move up and down within the housing 11. This movement is caused by the tension applied by the user and transmitted through the elastic body 103. The range and manner of movement directly affect the change in the distance between the magnet 16 and the Hall element 15 of the Hall sensor 13, thereby affecting the sensor reading.

[0063] like Figure 3 and Figure 4 As shown, a boss v is provided on the inner wall of the housing 11. This structure provides support and positioning for the movable connection portion 14. The width of the boss v is comparable to that of the frame body a. This technical approach allows the boss v to fit neatly into the inner cavity a1 of the frame body a, ensuring stability and precision when the movable connection portion 14 moves within the housing 11. The boss v not only provides physical support but also helps ensure the correct position of the spring 15, making the force transmission of the entire tensioning device 100 more efficient.

[0064] Furthermore, the lower end of spring 15 rests on boss v, ensuring that spring 15 provides a stable and consistent restoring force when compressed. The upper end of spring 15 rests on the top wall of inner cavity a1. This structure ensures that spring 15 maintains proper axial force transmission during tension and compression. The annular connection a3 is connected to the end of the elastic body 103. This connection allows the elastic body 103 to accurately transmit force to the movable connection 14 when stretched or relaxed, thereby driving the entire dynamometer's operating mechanism.

[0065] This technical solution not only ensures the stability and accuracy of the tensioning device 100 during use, but also helps improve its durability and ease of maintenance. The coordinated use of boss v and spring 15, as well as the connection between annular connection a3 and elastic body 103, together constitute the core mechanical components of the tensioning device 100, ensuring that users can achieve instant and accurate counting response and recording when using the tensioning device.

[0066] Preferably, Figure 6 As shown, the annular connecting portion a3 has an entry opening for the flexible elastic body 103 to be easily inserted. More preferably, the insertion opening is the distance formed by one end of the annular connecting portion a3 and the bottom end of the frame body a, that is, the gap formed when one end of the annular connecting portion a3 is not connected to the frame body a.

[0067] The lower end of the housing 11 is provided with an opening k, through which the lower end of the movable connector 14 can enter and exit. The elastic body 103 needs to be able to freely expand and contract during use of the tensioning device 100. The opening k ensures that the elastic body 103 is not obstructed during these movements, thereby ensuring smooth and accurate transmission of the tensioning force.

[0068] like Figure 5 As shown, housing 11 comprises a front housing 111 and a rear housing 112. The split design of front and rear housings 111 and 112 simplifies assembly and maintenance of the various components. When connected, front and rear housings 111 and 112 create a space for mounting display 30, circuit board 12, and articulating joint 14. This technical approach makes it easier to install display 30, circuit board 12, and articulating joint 14 within housing 11. Furthermore, when replacement or repair is necessary, either the front or rear housing can be removed independently without disassembling the entire device.

[0069] Furthermore, the design of the front and rear housings allows for a more flexible spatial layout. The display screen 30, circuit board 12, and movable connection portion 14 can be rationally arranged within the housing 11 to achieve optimal performance and user experience.

[0070] Preferably, the boss v is formed by a protrusion on the inner wall of the rear shell 112. This technical solution allows the boss v to form a single unit with the rear shell 112, thereby improving the structural stability and integrity of the housing 11. At the same time, this integrated design also helps reduce the complexity and potential connection problems during the assembly process because it eliminates additional components and connection points, thereby reducing manufacturing costs and maintenance difficulties.

[0071] Furthermore, the display screen 30 is located at the top of the housing 11. This layout provides the user with an intuitive, easy-to-read interface, allowing the user to conveniently view and monitor the operating status of the tensioning device 100. Furthermore, placing the display screen 30 at the top of the housing prevents accidental damage to the display screen during use of the tensioning device and also helps improve the readability of the display screen, especially outdoors or in brightly lit environments.

[0072] Preferably, the display screen 30 in this embodiment not only displays the calories consumed in real time, but also provides the corresponding number of kilometers of running required to achieve the calorie consumption, providing the user with more comprehensive health and exercise data.

[0073] Furthermore, raised guides a31 are provided on either side of the annular connection portion a3, and guide grooves 113 are provided on the front and rear sides of the housing 11 for limiting the sliding movement of the raised guides a31. The coordinated use of the raised guides a31 and guide grooves 113 ensures precise positioning of the movable connection portion 14 during movement within the housing 11. This precise guidance reduces friction and wear between the movable connection portion 14 and the inner wall of the housing 11 during movement. More importantly, the design of the raised guides a31 and guide grooves 113 enhances the structural stability between the movable connection portion 14 and the housing 11, ensuring stability even under high tensile forces.

[0074] In summary, the technical means of the raised guide portion a31 of the annular connecting portion a3 and the guide groove 113 of the housing 11 provide the tensioning device 100 with precise, stable and durable mechanical motion guidance.

[0075] Preferably, if Figure 5 and Figure 6 As shown, two vertical guide plates 117 are provided on the rear shell 112, and the frame body a is located in the guide plates 117. The vertical guide plates 117 provide precise vertical guidance for the movable connection part 14, ensuring its accuracy when moving up and down in the shell 11, reducing unnecessary shaking or deviation.
