[0031] Reference Figure 1-5As shown, a quick-release battery compartment can be detachably installed in a smart dumbbell, including a compartment body 100, wherein the compartment body 100 is provided with a semi-open battery 200 slot 110, and the battery 200 slot 110 is used to accommodate a battery 200;

[0032] The housing 100 is provided with a positive terminal and a negative terminal. The negative terminal of the housing 100 is provided with a notch 120 for an external negative electrode spring to pass through. The positive terminal of the housing 100 is provided with a positive electrode spring 300. The positive electrode spring 300 is used to connect the positive electrode of the battery 200 with the external positive electrode power supply contact 500.

[0033] The housing 100 is provided with a lock buckle 600 groove 130 for cooperating with an external lock buckle 600.

[0034] The quick-release battery compartment adopts a modular design, making the replacement of the battery 200 simple and quick, and also convenient for the maintenance and upgrade of the battery compartment. The design takes into account the convenience of user operation, and reduces the time and complexity of replacing the battery 200 through the quick-release mechanism.

[0035] The user puts the battery 200 into the semi-open battery 200 slot 110, and the two sides of the battery 200 will be fixed by the elastic buckle 140 to ensure that the battery 200 will not loosen during the use of the dumbbell. The positive pole of the battery 200 is connected to the external positive power supply contact 500 through the positive pole spring 300, and the negative pole is connected to the external negative pole spring through the notch 120 at the negative end to form a closed circuit. When the battery compartment is correctly placed in the designated position in the smart dumbbell handle, the lock buckle 600 will slide into the lock buckle 600 slot 130 to fix the battery compartment to prevent the battery compartment from accidentally falling off during use.

[0036] The quick-release design allows users to quickly replace the battery 200 without tools, which improves the efficiency of use. Compared with the built-in lithium battery 200 solution, the quick-release battery compartment may reduce the overall cost because it allows the use of standard batteries 200 and reduces the need for dedicated power management chips. The modular design makes the maintenance and upgrade of the battery compartment more convenient and extends the service life of the product. The design of the battery compartment makes it difficult to detect inside the smart dumbbell handle, keeping the product appearance neat and beautiful.

[0037] In this embodiment, elastic buckles 140 are provided on both sides of the battery 200 slot 110;

[0038] When the battery 200 is installed, the elastic buckle 140 can be squeezed by the battery 200 to deform into an outer shape;

[0039] When the battery 200 is located in the half-open battery slot 110 , the elastic buckles 140 on both sides buckle the upper half of the battery 200 inwardly.

[0040] The design uses an elastic buckle 140 as a fixing element for the battery 200, and uses the principle of elastic deformation to achieve rapid installation and firm fixation of the battery 200. The battery 200 slot 110 is designed to be semi-open, so that the user can intuitively see the installation status of the battery 200 and facilitate the insertion and removal of the battery 200. The design takes into account the operational convenience of the user when replacing the battery 200, and reduces the user's operating steps through a simplified mechanical structure.

[0041] The user aligns the battery 200 with the battery 200 slot 110, and the two sides of the battery 200 will contact the elastic buckle 140. When the battery 200 is pushed into the battery 200 slot 110, the elastic buckles 140 on both sides are squeezed by the battery 200 and elastically deformed, providing preliminary fixation for the battery 200. As the battery 200 is pushed in further, the elastic buckle 140 deforms to the maximum, and the battery 200 is completely located in the battery 200 slot 110. The elastic buckle 140 returns to its original state and buckles the upper half of the battery 200 inward to achieve a firm fixation of the battery 200. The design of the elastic buckle 140 allows the user to quickly push the battery 200 into the battery 200 slot 110 for quick installation. After the battery 200 is fully pushed in, the elastic buckle 140 can firmly buckle the battery 200 to prevent the battery 200 from loosening or falling off during the use of the dumbbell. When the battery 200 needs to be replaced, the user can easily remove it by simply pulling the battery 200 lightly. The elastic deformation of the elastic buckle 140 provides a convenient battery 200 removal mechanism. Compared with the complex mechanical locking structure, the elastic buckle 140 has a simple design and a low manufacturing cost, which helps to reduce the overall product cost.

[0042] In this embodiment, the positive electrode spring 300 is U-shaped, and the positive end of the chamber 100 is provided with a mounting groove 150 that communicates with the battery 200 groove 110;

[0043] The positive electrode spring piece 300 is clamped and fixed in the installation groove 150 . Windows are arranged on both sides of the installation groove 150 . The positive electrode spring piece 300 extends from the battery 200 slot 110 to the window on the side of the compartment body 100 .

[0044] The embedded design maintains the structural integrity of the bin body 100 and avoids structural interruption caused by penetrating the bin body 100. The U-shaped spring is fixed in the mounting groove 150 by a snap-fit ​​method, which simplifies the installation process. The embedded spring is connected to the external contact through the window, providing a stable electrical connection path.

[0045] The U-shaped spring clip is snapped into the installation slot 150 to ensure that it is in the correct position between the battery 200 slot 110 and the warehouse body 100. After the battery 200 is installed, the opening of the U-shaped spring clip contacts the positive electrode of the battery 200 to form a preliminary electrical connection. The spring clip extends from the battery 200 slot 110 to the window on the side of the warehouse body 100, and connects to the external power supply positive contact to complete the circuit closure.

[0046] The shrapnel is not exposed outside the housing 100, which keeps the appearance of the smart dumbbell neat and consistent. The embedded design avoids penetrating the housing 100, thereby maintaining the overall structural strength of the housing 100 and improving durability.

[0047] In this embodiment, a conductive boss 310 is provided at the end of the positive electrode spring piece 300, and the surface of the conductive boss 310 at both ends of the positive electrode spring piece 300 is higher than the side surface of the chamber body 100;

[0048] The positive electrode spring piece 300 is fixed on the housing 100 , and two ends of the positive electrode spring piece 300 can be compressed and brought close to each other.

[0049] The conductive boss 310 at the end of the positive shrapnel 300 is a key part for achieving a stable connection with the smart dumbbell. Both ends of the positive shrapnel 300 are designed to be compressible, allowing pressure to be applied to the shrapnel during installation or adjustment to meet different installation requirements. The insertion of the battery compartment is not affected by the compressibility of the shrapnel, and the user can easily install the battery compartment into the smart dumbbell. The height of the boss is designed to take into account wear during long-term use, and it can maintain its functionality even after multiple compressions and adjustments. Even after the shrapnel is compressed, the height of the conductive boss 310 can still ensure stable contact with the positive contact of the smart dumbbell, ensuring the continuity and stability of the electrical connection.

[0050] In this embodiment, the chamber body 100 is provided with a limiting plane along the axial direction, and the limiting plane is used to limit the rotation of the chamber body 100. The chamber body 100 is provided with one or more limiting planes along the axial direction, and these planes serve as physical barriers to prevent the chamber body 100 from rotating inside the smart dumbbell. The limiting plane interacts with the corresponding structure inside the smart dumbbell to ensure that the battery chamber is fixed in position after installation.

[0051] When the battery compartment is inserted into the smart dumbbell, the limiting plane contacts the corresponding structure inside the smart dumbbell to achieve the initial positioning of the battery compartment. During the use of the smart dumbbell, due to the action of the limiting plane, the battery compartment will not rotate and maintain its fixed position. The stable position of the battery compartment ensures the stable contact between the conductive boss 310 of the positive shrapnel 300 and the positive contact of the smart dumbbell, thereby ensuring the continuity and stability of the power supply.

[0052] In this embodiment, the transverse cross-section of the housing 100 is asymmetrical. The transverse cross-section of the housing 100 is designed to be asymmetrical, which allows the battery compartment to have a specific insertion direction. The asymmetrical cross-section serves as part of the foolproof mechanism to ensure that the battery compartment can only be inserted into the smart dumbbell in the correct direction.

[0053] When inserting the battery compartment, the user can identify the correct insertion direction by observing the asymmetric shape of the compartment body 100. The asymmetric design of the battery compartment allows it to fully fit into the internal structure of the smart dumbbell only when it is aligned in a specific direction. If the battery compartment is attempted to be inserted in the wrong direction, the asymmetric profile will prevent it from fully entering, thereby avoiding incorrect installation.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
