[0001] The utility model belongs to the technical field of intelligent dumbbells, and relates to an intelligent dumbbell with quick-disassembly of bell plates. Background Art

[0002] Intelligent dumbbells generally refer to a kind of fitness equipment integrated with technological elements, aiming to provide a more intelligent and personalized fitness experience. Different from traditional dumbbells, the handle part of intelligent dumbbells requires an integrated circuit control part, and the loading and unloading of the handle part and the bell plates are no longer in the way of screw connection, and a quick-installation structure is mostly adopted.

[0003] There are various quick-disassembly structures for the bell plates of existing intelligent dumbbells on the market, but they more or less affect the user experience, appearance aesthetics, structural strength and cost. The weakest part of the structural strength is at the lock. The structure is either relatively complex or additional hardware parts need to be added, and the cost is relatively high. When loading and unloading the bell plates, it is necessary to unlock first. Content of the Utility Model

[0004] The purpose of the utility model is to provide an intelligent dumbbell with quick-disassembly of bell plates aiming at the deficiencies of the existing technology, and through the clamping fit of elastic protrusions and limiting grooves, the purpose of quickly loading and unloading the bell plates and preventing the bell plates from falling off accidentally is achieved.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An intelligent dumbbell with quick-disassembly of bell plates, comprising a dumbbell main body and a bell plate assembly detachably connected to the dumbbell main body;

[0007] Clamping grooves are arranged at both ends of the dumbbell main body, and a clamping boss is arranged on one side of the bell plate assembly;

[0008] A limiting flange is arranged at the opening of the clamping groove, and a clamping claw is arranged on the side wall of the clamping boss. When the clamping boss is located in the clamping groove, the bell plate assembly is rotated to make the clamping claw correspond to the limiting flange for fixing the limiting flange;

[0009] Wherein, an elastic protrusion is arranged on the inner side of the limiting flange, and a limiting groove corresponding to the elastic protrusion is arranged on the inner side of the clamping claw. When the groove on the clamping claw corresponds to the elastic protrusion, the elastic protrusion is located in the limiting groove.

[0010] Furthermore, the elastic protrusion is a telescopic steel ball, and the edge of the limiting groove is provided with a fillet.

[0011] Furthermore, the sum of the thickness of the clamping claw and the thickness of the limiting flange is equal to the depth of the limiting groove.

[0012] Further, one side of the weight plate assembly is provided with a clamping boss, and the other side is provided with a clamping groove. Adjacent weight plate assemblies are detachably connected through the clamping boss and the clamping groove.

[0013] Further, the side surfaces of the weight plate assembly and the dumbbell body are provided with identification parts.

[0014] Further, the weight plate assembly includes a weight plate housing, a weight plate counterweight, and a weight plate end cap;

[0015] The weight plate housing is fixedly connected to the weight plate end cap. A cavity is formed between the weight plate housing and the weight plate end cap, and the weight plate counterweight is fixed in the cavity.

[0016] Further, dumbbell body counterweights are symmetrically arranged at the left and right ends inside the dumbbell body.

[0017] Further, a cavity is provided inside the handle of the dumbbell body. The opening of the cavity is located in the clamping groove, and a detachable battery compartment is provided inside the cavity.

[0018] Applying the technical solution of the present utility model, through the design of the clamping groove and the clamping boss, and in cooperation with the clamping of the elastic protrusion and the limiting groove, the rapid loading and unloading of the weight plate are realized, improving the user experience. The cumbersome steps in the traditional dumbbell loading and unloading process are simplified, improving the convenience for the user, enabling the user to quickly adjust the dumbbell weight according to the exercise needs in a short time. The elastic protrusion and the limiting groove are clamped and matched to fix the weight plate assembly.

[0031] Reference appendix Figure 1-6 As shown, an intelligent dumbbell with quick-release discs includes a dumbbell body 100 and a disc assembly 200 detachably connected to the dumbbell body 100;

[0032] At both ends of the dumbbell body 100, there are clamping grooves 300, and on one side of the disc assembly 200, there is a clamping boss 400;

[0033] At the opening of the clamping groove 300, there is a limiting flange 310, and on the side wall of the clamping boss 400, there are clamping claws 410. When the clamping boss 400 is located within the clamping groove 300, rotate the disc assembly 200 so that the clamping claws 410 correspond to the limiting flange 310 for fixing the limiting flange 310;

[0034] Among them, on the inner side of the limiting flange 310, there is an elastic protrusion 320, and on the inner side of the clamping claw 410, there is a limiting groove 420 corresponding to the elastic protrusion 320. When the clamping groove on the clamping claw 410 corresponds to the elastic protrusion 320, the elastic protrusion 320 is located within the limiting groove 420. The dumbbell body 100 and the disc assembly 200 adopt a detachable connection method to achieve modularization, facilitating users to quickly replace the disc assembly 200 according to exercise needs. Through the cooperation of the clamping groove 300 and the clamping boss 400, quick loading and unloading are achieved, simplifying the operation process. The elastic protrusion 320 and the limiting groove 420 are designed to ensure the stability of the disc assembly 200 during movement and prevent accidental detachment.

[0035] The clamping grooves 300 at both ends of the dumbbell body 100 are designed to receive the clamping bosses 400 of the disc assembly 200. When the clamping boss 400 is inserted into the clamping groove 300, by rotating the disc assembly 200, the clamping claws 410 and the limiting flange 310 interact to achieve fixation. The elastic protrusion 320 on the inner side of the limiting flange 310 cooperates with the limiting groove 420 on the inner side of the clamping claw 410. When the two correspond, the elastic protrusion 320 is embedded in the limiting groove 420, providing a stable fixing force. The elastic effect of the elastic protrusion 320 ensures that even during strenuous exercise, the disc assembly 200 can remain stable and prevent detachment due to vibration or impact.

[0036] Users can quickly load and unload the weight plate assembly 200 without complex steps or tools, improving the ease of use. The design of the clamping groove 300 and the clamping boss 400 provides a stable connection, ensuring that the weight plate assembly 200 will not accidentally separate during use. The combined use of the elastic protrusion 320 and the limiting groove 420 provides additional safety protection and reduces the risk of injury during exercise. The hidden elastic protrusion 320 design keeps the product appearance clean and beautiful. Through the design of the clamping groove 300 and the clamping boss 400, the direct contact during the loading, unloading and use of the weight plate assembly 200 is reduced, thereby reducing surface wear. The appearance design of the weight plate assembly 200 can remain novel for a long time, enhancing the overall visual effect of the product.

[0037] In this embodiment, the elastic protrusion 320 is a telescopic steel ball, and the edge of the limiting groove 420 is provided with a rounded corner. The main goal of the design is to ensure the smoothness of the disassembly and installation process and avoid jamming. The telescopic steel ball serves as the elastic protrusion 320, allowing a certain degree of expansion and contraction, ensuring that users can easily operate when loading and unloading the weight plate assembly 200 without additional tools or complex steps.

[0038] The rounded corner design at the edge of the limiting groove 420 makes the telescopic steel ball smoother during the clamping and disengaging processes, reducing resistance and friction. When the claw 410 of the weight plate assembly 200 carries the telescopic steel ball and aligns with the limiting groove 420 and inserts, the steel ball is compressed and then expands to fix the weight plate assembly 200; when released, the steel ball is compressed again, allowing the weight plate assembly 200 to disengage.

[0039] An elastic protrusion 320 is provided on the inner side of the limiting flange 310, and the claw 410 and the limiting flange 310 are buckled inward in the opposite direction to form a fixation. During long-term use, the scratches caused by the elastic protrusion 320 on the surface of the claw 410 are located inside the claw 410 and are difficult to detect in the visual blind spot.

[0040] In this embodiment, the sum of the thickness of the claw 410 and the thickness of the limiting flange 310 is equal to the depth of the limiting groove 420. Ensure that the total thickness of the claw 410 and the limiting flange 310 exactly matches the depth of the limiting groove 420. Avoid gaps caused by size mismatches, ensure a tight fit between the weight plate assembly 200 and the dumbbell body 100. By reducing the gap, improve the stability of the weight plate assembly 200 during movement and prevent loosening or falling off.

[0041] When the jaw 410 is inserted into the limit groove 420, the sum of its thickness and the thickness of the limit flange 310 exactly fills the limit groove 420, achieving a tight fit. The tight combination of the jaw 410 and the limit flange 310 provides a fixing force through the matching of physical dimensions, maintaining the stability of the weight plate assembly 200. The elastic protrusion 320 such as a telescopic steel ball inside the jaw 410 further enhances the fixing force, ensuring that the weight plate assembly 200 will not loosen when subjected to an external force.

[0042] In this embodiment, a clamping boss 400 is provided on one side of the weight plate assembly 200, and a clamping groove 300 is provided on one side. Adjacent weight plate assemblies 200 are detachably connected through the clamping boss 400 and the clamping groove 300. Through the cooperation of the clamping boss 400 and the clamping groove 300, the weight plate assembly 200 can be disassembled and connected quickly and simply. The user only needs to insert the clamping boss 400 into the clamping groove 300 to complete the connection of the weight plate assembly 200. Conversely, the user only needs to pull out the clamping boss 400 to disassemble the weight plate assembly 200. The weight plate assembly 200 realizes a detachable connection through the cooperation of the clamping boss 400 and the clamping groove 300. This means that the user can freely combine the weight plate assemblies 200 according to needs, flexibly adjusting the weight and training intensity. The clamping design of the weight plate assembly 200 enables it to be connected to other weight plate assemblies 200 or the dumbbell body 100, providing greater flexibility and diversity to adapt to different training needs.

[0043] In this embodiment, a marking portion 600 is provided on the side of the weight plate assembly 200. The direction of the marking portion 600 corresponds to the direction of the limit steel ball for distinguishing the direction of the weight plate assembly 200. A marking portion 600 is specially designed on the side of the weight plate assembly 200. This marking portion 600 can be a logo, symbol, text, or color distinction, etc., for indicating the correct direction of the weight plate assembly 200. The direction of the marking portion 600 corresponds to the installation direction of the limit steel ball inside the weight plate assembly 200. The limit steel ball is used to ensure the correct alignment and fixation of the weight plate assembly 200 during the screwing process. When the weight plate assembly 200 is correctly screwed in place, the marking portion 600 will be in a preset direction, such as upward, so that the user can intuitively see the marking portion 600 and confirm that the weight plate assembly 200 has been correctly installed. If the weight plate assembly 200 is not screwed in place, the direction of the marking portion 600 will be incorrect, and the user can quickly discover and make adjustments to avoid the use risks caused by improper installation.

[0044] The design of the identification part 600 enables users to intuitively judge whether the weight plate assembly 200 is properly installed, thus reducing the accidental risks caused by improper installation. Through the indication of the identification part 600, users can easily confirm the installation status of the weight plate assembly 200 without complex inspections or guesswork, making the usage process more convenient and efficient. For beginners or gym coaches, the identification part 600 provides a clear reference point for teaching and learning the correct installation method.

[0045] In this embodiment, the weight plate assembly 200 includes a weight plate housing 210, weight plate counterweights 220, and a weight plate end cap 230;

[0046] The weight plate housing 210 is fixedly connected to the weight plate end cap 230, a cavity is formed between the weight plate housing 210 and the weight plate end cap 230, and the weight plate counterweights 220 are fixed in the cavity. By fixing the weight plate counterweights 220 in the cavity formed by the weight plate housing 210 and the end cap, the integration of the appearance is achieved. The unified appearance reduces the visual clutter and provides a better visual experience. Ensure the structural stability of the weight plate assembly 200, enabling it to remain stable during various exercises. While ensuring practicality, attention is paid to the aesthetic appearance of the product to provide a good visual experience.

[0047] In this embodiment, weight plate counterweights 110 are symmetrically arranged at the left and right ends inside the dumbbell body 100. The dumbbell body 100 comes with built-in counterweights, enabling it to be used independently as a lightweight exercise tool. Users can choose to use the built-in counterweights of the dumbbell body 100 or add additional weight plate assemblies 200 according to their exercise needs. The design takes into account the exercise intensities and habits of different users, providing a variety of exercise options from light to heavy. The symmetrically arranged counterweights at both ends ensure the balance of the dumbbell during use and avoid exercise injuries caused by uneven weight distribution. The dumbbell body 100 can be used as an independent tool or in combination with other weight plate assemblies 200 to provide multifunctional exercise options.

[0048] In this embodiment, a cavity is provided inside the handle of the dumbbell body 100, the opening of the cavity is located in the clamping groove 300, and a detachable battery compartment 500 is provided inside the cavity.
