[0040] Refer to the attached Figure 1-6 As shown, an intelligent dumbbell with a quick-release battery includes a dumbbell main body 100, a counterweight 200, and a battery compartment 300;

[0041] One end of the dumbbell main body 100 is provided with a battery cavity 110, and the battery compartment 300 is detachably fixed in the battery cavity 110;

[0042] The counterweight 200 is detachably connected to both ends of the dumbbell main body 100, and the counterweight 200 covers the opening of the battery cavity 110. By adopting an electric compartment that can install dry batteries, the dependence on the built-in lithium battery solution is reduced, thereby reducing the production cost. As a widely used and low-cost power supply solution, dry batteries make the intelligent dumbbell more affordable and improve the market competitiveness of the product. The counterweight 200 covers the opening of the battery cavity 110, maintaining the integrity of the dumbbell appearance and making the product more visually appealing. This design is both practical and aesthetically pleasing, enhancing the attractiveness of the product. The quick-release battery design allows users to easily replace the battery without worrying about power depletion. This design improves the convenience of use, so that users will not interrupt their training due to battery problems during fitness.

[0043] In this embodiment, a conductive negative electrode spring 120 is provided at the bottom of the battery cavity 110, and a conductive positive electrode elastic piece 130 is provided on the side wall of the battery cavity 110. The battery cavity 110 is a special space inside the intelligent dumbbell, specifically for accommodating the battery compartment 300. A conductive negative electrode spring 120 and a conductive positive electrode elastic piece 130 are respectively provided at the bottom and the side wall of the battery cavity 110. When the battery compartment 300 is installed into the battery cavity 110, the negative electrode of the battery contacts the conductive negative electrode spring 120 at the bottom, while the positive electrode of the battery contacts the conductive positive electrode elastic piece 130 on the side wall, forming a closed circuit to supply power to the electronic module of the intelligent dumbbell. When it is necessary to disassemble the battery compartment 300, in addition to providing a stable power connection, the conductive negative electrode spring 120 also has a special function, that is, it can eject the battery out of the battery cavity 110 during the disassembly process. This is usually achieved through the mechanical action of the spring, possibly by compressing or stretching the spring to push the battery outward.

[0044] The ejection function of the conductive negative electrode spring 120 greatly simplifies the battery replacement process. When the user disassembles the battery compartment 300, there is no need to manually take out the battery, and the battery will automatically pop out with the action of the spring, which improves the efficiency and convenience of replacing the battery. The automatic ejection function simplifies the maintenance process of the intelligent dumbbell, and the user can perform daily maintenance and inspection more easily to ensure that the device is always in the best working condition.

[0045] In this embodiment, an installation groove is provided on the surface of the battery compartment 300, and a power supply is detachably fixed in the installation groove;

[0046] One end of the battery compartment 300 facing the bottom of the battery cavity 110 is provided with a notch 310 for the conductive negative electrode spring 120 to pass through, and the conductive negative electrode spring 120 passes through the notch 310 and is electrically connected to the negative electrode of the power supply;

[0047] At the other end of the battery compartment 300, there is a conductive sheet 320 which extends from the installation groove to the side of the battery compartment 300. The conductive sheet 320 is used to conduct the positive power supply and the conductive positive electrode elastic sheet 130. The battery compartment 300 is a component inside the smart dumbbell for accommodating the power module. There is an installation groove on the surface of the battery compartment 300, and the power module can be fixed in this installation groove. The power module provides the required power for the smart dumbbell. One end of the battery compartment 300 facing the bottom of the battery cavity 110 is provided with a notch 310 which allows the conductive negative spring 120 to pass through and connect to the negative electrode of the power module, thus forming the negative connection of the circuit. At the other end of the battery compartment 300, there is a conductive sheet 320 which extends from the installation groove to the side of the battery compartment 300. The function of the conductive sheet 320 is to connect the positive electrode of the power module to the conductive positive electrode elastic sheet 130 in the battery cavity 110, forming the positive connection of the circuit. When the battery compartment 300 is correctly installed in the battery cavity 110, the conductive negative spring 120 and the conductive sheet 320 are respectively connected to the corresponding conductive positive electrode elastic sheet 130 and the positive electrode of the power module, the circuit is closed, and the electronic module of the smart dumbbell gets power supply and can work normally.

[0048] The power module in the battery compartment 300 adopts a detachable fixing method, which is convenient for replacement and maintenance. This modular design improves the maintainability and upgradability of the smart dumbbell. Through the design of the conductive negative spring 120 and the conductive sheet 320, the stable connection between the power module and the internal circuit of the smart dumbbell is ensured, providing a continuous and stable power supply. The design of the battery compartment 300 allows for quick assembly and disassembly. Users can easily replace the battery or perform maintenance, improving the convenience of use. The design of the installation groove and the conductive sheet 320 in the battery compartment 300 optimizes the utilization of the internal space of the smart dumbbell, enabling the power module and the conductive components to be compactly installed in a limited space. By providing an easy-to-operate design of the battery compartment 300, users can replace the battery and perform maintenance without worry, thus obtaining a better fitness experience.

[0049] In this embodiment, the conductive sheet 320 is U-shaped, and there are conductive bosses 330 at the ends of the conductive sheet 320. The surfaces of the conductive bosses 330 at both ends of the conductive sheet 320 are higher than the side of the battery compartment 300;

[0050] The conductive sheet 320 is fixed on the battery compartment 300, and both ends of the conductive sheet 320 can be compressed and brought closer.

[0051] At the end of the conductive sheet 320, there are conductive bosses 330, and the surfaces of these bosses are higher than the side surface of the battery compartment 300. Such a design enables the conductive bosses 330 to contact the conductive positive electrode elastic sheet 130 or other contact points in the battery cavity 110 to form the positive electrode connection of the circuit. The conductive sheet 320 is fixed on the battery compartment 300, and its two ends have compressibility, which means that the conductive sheet 320 can be elastically deformed as needed, and the conductive sheet 320 does not prevent the battery compartment 300 from being pushed into the battery cavity 110.

[0052] The design of the U-shaped conductive sheet 320 and the conductive bosses 330 provides a stable electrical connection, ensuring that the electronic module of the smart dumbbell can continuously receive power, thus guaranteeing its normal operation. The compressibility of the conductive sheet 320 allows it to adapt to different space and connection conditions during installation, which helps to reduce the stress during installation and ensure long-term reliability. The design that the conductive bosses 330 are higher than the side surface of the battery compartment 300 helps to ensure that even when the battery compartment 300 is under a certain pressure or vibration, the electrical connection is still reliable, reducing the risk of failures caused by poor contact.

[0053] In this embodiment, the battery compartment 300 is provided with a limiting plane 340 along the axial direction, the battery cavity 110 is in close contact with the limiting plane 340, and the limiting plane 340 is used to limit the rotation of the battery compartment 300. When the battery compartment 300 is installed into the battery cavity 110, it is in close contact with the limiting plane 340. This contact ensures the correct positioning of the battery compartment 300 in the cavity, preventing it from rotating or shifting during movement or use. The main function of the limiting plane 340 is to limit the rotation of the battery compartment 300, ensuring that the power connection points in the battery compartment 300 are correctly aligned and in contact with the conductive springs and elastic sheets in the battery cavity 110.

[0054] By restricting the rotation of the battery compartment 300, the limiting plane 340 ensures the stability of the power connection, avoiding problems of poor contact or power-off caused by the movement or rotation of the battery compartment 300. The existence of the limiting plane 340 makes the installation of the battery compartment 300 simpler and more direct. The user only needs to push the battery compartment 300 into the battery cavity 110 in the correct direction, and the limiting plane 340 will automatically align and lock the battery compartment 300, reducing the possibility of installation errors.

[0055] Refer to the attached Figure 3-4 As shown, in the first embodiment, a pressing lock 510 is provided at the bottom of the battery cavity 110, and a male lock 500 is provided at one end of the battery compartment 300 facing the bottom of the battery cavity 110;

[0056] The pressing lock 510 engages or releases the male lock 500 for the detachable connection between the battery compartment 300 and the battery cavity 110.

[0057] At the bottom of the battery cavity 110, there is a push lock 510, which is a mechanical structure used to realize the fixation and disassembly between the battery compartment 300 and the battery cavity 110. At one end of the battery compartment 300 facing the bottom of the battery cavity 110, there is a male lock 500, which cooperates with the push lock 510 to fix the battery compartment 300. When installing the battery compartment 300, the user presses the push lock 510 to align and engage the male lock 500 with the push lock 510, thereby fixing the battery compartment 300 in the battery cavity 110. When disassembling the battery compartment 300, the user presses the push lock 510 again to separate the male lock 500 from the push lock 510, thereby releasing the battery compartment 300.

[0058] The design of the push lock 510 makes the disassembly of the battery compartment 300 fast and simple. Users can easily replace the battery or perform maintenance without using tools or other auxiliary devices. The engagement between the male lock 500 and the push lock 510 provides a stable fixing method, ensuring that the battery compartment 300 will not loosen during use, thus guaranteeing the stability and safety of the smart dumbbell. The push-button design enables users to complete the installation and disassembly of the battery compartment 300 with a simple pressing action, improving the user experience.

[0059] In the first implementation case, the male lock 500 is eccentrically arranged at the end of the battery compartment 300, and the upper and lower sides of the cross-section of the battery compartment 300 are asymmetric structures. The eccentric design is to avoid the conductive negative spring 120. Such a design makes the male lock 500 can only be correctly aligned with the corresponding push lock 510 during assembly. The eccentric design of the male lock 500 helps to ensure that the conductive negative spring 120 can be correctly aligned with the conductive structure in the battery cavity 110 during the assembly of the battery compartment 300, thus guaranteeing the accuracy and reliability of the electrical connection.

[0060] The cross-section of the battery compartment 300 is designed as an asymmetric structure, which means that the upper and lower sides of the battery compartment 300 have different shapes, providing a clear indication of the assembly direction. The design of the asymmetric structure intuitively indicates the correct assembly direction of the battery compartment 300, avoiding assembly failures or poor contacts caused by incorrect directions. The simplified assembly process and intuitive design reduce the user's learning cost, enabling users to be more relaxed and confident when using the smart dumbbell.

[0061] Reference attached Figure 5-6 As shown, in the second implementation case, a toggle switch 610 is slidably installed at the opening of the battery cavity 110;

[0062] The battery compartment 300 is provided with a notch 600 corresponding to the toggle switch 610;

[0063] The toggle switch 610 has two position states: retracted and extended. When the toggle switch 610 is in the retracted position state, the battery compartment 300 can slide freely within the battery cavity 110. When the toggle switch 610 is in the extended position state, the locking tongue portion of the toggle switch 610 is located within the notch 600 of the battery compartment 300 to restrict the sliding of the battery compartment 300.

[0064] By retracting and extending the toggle switch 610, the user can conveniently control the fixation and release of the battery compartment 300. When replacing the battery or performing maintenance, the user only needs to switch the toggle switch 610 to the retracted position to remove the battery compartment 300. After completing the operation, switch the toggle switch 610 back to the extended position to fix the battery compartment 300.

[0065] The design of the toggle switch 610 provides a simple and intuitive operation method. The user can easily control the fixation and release of the battery compartment 300 without using tools or other auxiliary devices. When in the extended position, the locking tongue portion of the toggle switch 610 can firmly lock the battery compartment 300, preventing the battery compartment 300 from accidentally sliding or falling off during movement or use, thus improving the safety during use. This design allows the user to quickly remove and replace the battery compartment 300, improving the convenience of use, especially in cases where the battery needs to be replaced frequently.

[0066] In the second implementation case, a spring is provided between the toggle switch 610 and the dumbbell body 100. The spring is used to maintain the toggle switch in the extended position state. Between the toggle switch 610 and the dumbbell body 100, a spring mechanism is provided. The function of this spring is to keep the toggle switch 610 in the extended position state at all times when there is no external force. The function of the spring ensures that the toggle switch 610 will not accidentally return to the retracted position after use, thus avoiding the risk of accidental loosening of the battery compartment 300 and enhancing the safety during use. When the user switches the toggle switch 610 from the extended position to the retracted position to remove the battery compartment 300, the spring will be compressed. Once the user completes the replacement or maintenance of the battery compartment 300 and wishes to fix the battery compartment 300, just push the toggle switch 610 back to the extended position, and the spring will return to its original state and push the toggle switch 610 to maintain this position, thus locking the battery compartment 300.

[0067] In the second implementation case, a retreat inclined surface facing the opening is provided on the locking tongue portion of the toggle switch 610. When it is necessary to install or replace the battery compartment 300, the user can align the battery compartment 300 with the battery cavity 110 and directly push it in. During the pushing process, the battery compartment 300 will contact the retreat inclined surface of the locking tongue portion. Due to the effect of the retreat inclined surface, when the battery compartment 300 is pushed in, the locking tongue portion will be guided by the inclined surface and naturally move to the retracted position, thus not hindering the pushing-in of the battery compartment 300. The design of the retreat inclined surface makes the installation of the battery compartment 300 simpler and more direct, and the user can complete the installation of the battery compartment 300 without performing complex operations.

[0068] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
