DETAILED DESCRIPTION
[0019] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0021] Referring to Figures 1-2 The buckle assembly provided by the embodiments of the present disclosure comprises: a fixed part 100, a rotating part 200 and a locking part 300; the first end of the rotating part 200 is rotatably connected to the first end of the fixed part 100 through a first rotating shaft 101; the second end of the rotating part 200 is rotatably connected to the first end of the locking part 300 through a second rotating shaft; the first surface of the fixed part 100 is provided with a clamping seat 105; when the locking part 300 is in a locked state, the second end of the locking part 300 is locked with the second end of the fixed part 100, and the second surface of the fixed part 100 faces the first surface of the rotating part 200; when the locking part 300 is in a released state, the second end of the locking part 300 is separated from the second end of the fixed part 100.
[0022] In the embodiments, the double-rotating-shaft connection design between the rotating part 200 and the fixed part 100 and the locking part 300 enables the buckle assembly to smoothly transition between the locked and released states, enhances the flexibility of operation, reduces wear caused by direct hard contact, and thus improves the durability of the buckle assembly. In the locked state, the second end of the locking part 300 is tightly locked with the second end of the fixed part 100, enhancing the stability between the connected parts and preventing accidental loosening or falling off, and being suitable for application scenarios that need to withstand certain external forces or vibrations.
[0023] In actual application, the user can easily realize the locking and releasing of the buckle assembly by simply operating the locking part 300 (such as pressing, rotating, etc.), without the need for complex operation steps or tool assistance, improving the convenience of use. Due to the presence of the rotating part 200, the buckle assembly can occupy a smaller space in the locked and released states, which is particularly important for space-limited devices or products, such as small electronic products, compact tool boxes, etc.
[0024] Referring to Figures 1-2 , the buckle assembly has a folded state and an unfolded state. When the buckle assembly is in the folded state, the rotating member 200 is opposite and spaced apart from the fixed member 100, and a wearing cavity is formed between the rotating member 200 and the fixed member 100. The distance H between the rotating member 200 and the fixed member 100 in the third direction ZZ satisfies 0.5cm≤H≤1cm, and specifically, H can be 0.5cm, 0.6cm, 0.7cm, 0.8cm, 1cm or a value between any two of the above. When the distance H between the rotating member 200 and the fixed member 100 in the third direction is in the above range, the rotating member 200 and the fixed member 100 can stably clamp the wearing accessory, and the stability of the connection between the buckle assembly and the wearing accessory is improved.
[0025] In an implementation manner, the second end of the fixed member 100 is provided with a locking portion 102, and the second end of the locking member 300 is provided with a clamping groove, which is clamped on the locking portion 102 when the locking member 300 is in the locked state.
[0026] In the embodiment, the locking portion 102 and the clamping groove are designed to cooperate, so that in the locked state, the locking member 300 can be firmly clamped on the fixed member 100, thereby significantly enhancing the locking strength of the buckle assembly. The cooperation of the clamping groove and the locking portion 102 enables the locking member 300 to be accurately positioned on the fixed member 100 when locked, avoiding loose connection or looseness caused by position deviation. The user only needs to push or rotate the locking member 300 to the position of the locking portion 102 of the fixed member 100, and the clamping groove can be automatically clamped into the locking portion 102 to achieve quick locking. The locking structure of the clamping groove and the locking portion 102 enables the buckle assembly to form a stable force transmission path when subjected to force, thereby reducing the risk of structural damage caused by stress concentration.
[0027] Referring to Figures 2-3 , the locking portion 102 includes a locking rod 1021 and a first clamping groove 1022, the first clamping groove 1022 penetrates the fixed member 100 in the thickness direction of the fixed member 100, and the locking rod 1021 is located in the first clamping groove 1022. The locking member 300 has a second clamping groove 301, and when the locking member 300 is in the locked state, the locking member 300 is clamped on the locking rod 1021 through the second clamping groove 301, and the locking member 300 is at least partially located in the first clamping groove 1022.
[0028] Referring to Figures 2-3The second rotating shaft 201 is connected to the rotating member 200, the locking member 300 has a second clamping groove 301, the locking member 300 is connected to the second rotating shaft 201, and the locking member 300 can rotate relative to the rotating member 200 through the second rotating shaft 201. The locking member 300 is connected to the rotating member 200 through the second rotating shaft 201, so that the locking member 300 can freely rotate around the axis of the second rotating shaft 201, and the locking member 300 can be adjusted in position in multiple directions to adapt to the lock rod 1021 at different angles and positions, thereby improving the adaptability and flexibility of the installation position of the locking member 300 and the locking part 102.
[0029] In an implementation manner, the second rotating shaft is sleeved with a torsional spring 302, a first elastic arm of the torsional spring 302 is clamped at the second end of the rotating member 200, and a second elastic arm of the torsional spring 302 is clamped at the first end of the locking member 300.
[0030] In the embodiment, the torsional spring 302 provides the buckle assembly with the ability of automatic reset. When the locking member 300 is switched from the locked state to the released state, the torsional spring 302 pushes the locking member 300 back to the initial position by using the elastic potential energy. When the locking member 300 is in the locked state, the elastic force of the torsional spring 302 acts on the locking member 300, so that the locking member 300 is more closely attached to the fixing member 100, thereby enhancing the locking strength and improving the stability and reliability of the buckle assembly, and preventing accidental loosening caused by external force. During the locking or separation of the locking member 300 and the fixing member 100, the elastic force of the torsional spring 302 can play a certain buffering role, thereby reducing the impact and noise caused by direct hard contact.
[0031] In the embodiment, the second rotating shaft 201 is fixed relative to the rotating member 200, the locking member 300 is sleeved on the second rotating shaft 201, the two ends of the torsional spring 302 are bent to form a first elastic arm clamping and a second elastic arm clamping, the first elastic arm clamping of the torsional spring 302 is clamped at the second end of the rotating member 200, the second elastic arm clamping is clamped at the first end of the locking member 300, the locking member 300 rotates around the axis of the second rotating shaft 201, and the second rotating shaft 201 does not rotate by itself. When the buckle assembly is in the folded state, the locking member 300 is buckled on the lock rod 1021 under the elastic force of the torsional spring 302, and the continuous pressing force of the torsional spring 302 effectively prevents loosening caused by vibration or external force, thereby improving the stability and reliability of the connection between the locking member 300 and the lock rod 1021.
[0032] In the embodiment, one end of the torsional spring 302 is fixed relative to the rotating member 200, and the other end is fixed relative to the locking member 300. The locking member 300 is buckled on the lock rod 1021 under the elastic force of the torsional spring 302, and the continuous pressing force of the torsional spring 302 effectively prevents loosening caused by vibration or external force, thereby improving the stability and reliability of the connection between the locking member 300 and the lock rod 1021.
[0033] In an implementation, the torsion spring 302 is in a first deformed state when the locking member 300 is in the locked state, and the torsion spring 302 is in a second deformed state when the locking member 300 is in the released state, and the deformation amount of the first deformed state is less than that of the second deformed state.
[0034] In the embodiment, in the locked state, the torsion spring 302 is in the first deformed state with a relatively small deformation amount, and the torsion spring 302 provides a moderate and stable locking force for the locking member 300, thereby enhancing the stable connection of the buckle assembly. Since the deformation amount of the first deformed state is small, the elastic potential energy stored by the torsion spring 302 in the locked state is relatively small. When the locking member 300 is kept in the locked state for a long time, the stress concentration and wear of the material caused by the torsion spring 302 are small, which helps to prolong the service life of the buckle assembly. When the locking member 300 is switched from the locked state to the released state, the torsion spring 302 is changed from the first deformed state to the second deformed state with an increased deformation amount. The increase of the deformation amount enables the torsion spring 302 to release more elastic potential energy, thereby pushing the locking member 300 to separate quickly and smoothly.
[0035] In the embodiment, the difference in the deformation amount of the torsion spring 302 in different deformed states provides clear operation feedback to the user. In the locking process, the user can feel the gradually increasing resistance of the torsion spring 302, and in the releasing process, the user can feel the sudden release of the elastic force of the torsion spring 302 and the quick separation of the locking member 300.
[0036] Due to the presence of the torsion spring 302, the locking member 300 will cause the torsion spring 302 to deform in the locked state and the released state. When the locking member 300 is in the locked state, the torsion spring 302 is in the first deformed state, and when the locking member 300 is in the released state, the torsion spring 302 is in the second deformed state, and the deformation amount of the first deformed state is less than that of the second deformed state.
[0037] When the torsion spring 302 is in the first deformed state, the included angle between the first elastic arm and the second elastic arm is an acute angle, and when the torsion spring 302 is in the second deformed state, the included angle between the first elastic arm and the second elastic arm is an obtuse angle, and when the torsion spring 302 is switched from the first deformed state to the second deformed state, the included angle between the first elastic arm and the second elastic arm gradually increases.
[0038] In an implementation, when the torsion spring 302 is in the natural state or the first deformed state, the included angle between the first elastic arm and the second elastic arm is an acute angle, and when the torsion spring 302 is in the second deformed state, the included angle between the first elastic arm and the second elastic arm is an obtuse angle.
[0039] In the locked state, the acute angle between the first elastic arm and the second elastic arm of the torsion spring 302 allows the torsion spring 302 to store elastic potential energy more effectively. When the locking piece 300 switches from the locked state to the released state, the torsion spring 302 changes from the first deformation state to the second deformation state, and the included angle changes from acute to obtuse. In this case, the torsion spring 302 will release a large amount of elastic potential energy, pushing the locking piece 300 to separate quickly and smoothly. The design of the obtuse angle helps to achieve a smooth release action, reducing resistance and jamming during the release process.
[0040] Under the acute angle, the stress of the torsion spring 302 is mainly concentrated near the root of the elastic arm; under the obtuse angle, the stress distribution is relatively more uniform, reducing stress concentration and improving the durability and reliability of the torsion spring 302. As the locking piece 300 changes from locked to released, the torsion spring 302 needs to undergo a large deformation. The change of the included angle between the elastic arms (from acute to obtuse) in different deformation states can better adapt to the deformation demand, so that the torsion spring 302 can maintain stable performance output during the deformation process and will not fail or be damaged due to excessive deformation. The change of the included angle of the torsion spring 302 in different deformation states provides intuitive operation feedback to the user. The user can observe the change of the included angle to determine the state of the locking piece 300 (locked or released), so as to more accurately grasp the operation timing and force.
[0041] In one implementation, the second surface of the fixing piece 100 is provided with a flexible pad 103, which faces the rotating piece 200 when the locking piece 300 is in the locked state. When the locking piece 300 is in the locked state, the flexible pad 103 can fill the small gap between the fixing piece 100 and the rotating piece 200 or the locking piece 300, effectively preventing external impurities such as dust and moisture from entering the inside of the buckle assembly, thereby protecting the internal mechanical structure from corrosion and damage, and improving the sealing and durability of the buckle assembly. The flexible pad has good elasticity and cushioning effect, which can absorb and disperse the energy when the buckle assembly is subjected to external force impact or vibration, reducing the impact and damage to the internal mechanical structure and improving the shock resistance and stability of the buckle assembly.
[0042] In scenarios where the buckle assembly needs to be frequently operated, such as opening and closing of backpacks, tool boxes and other products, the presence of the flexible pad can reduce direct contact between the hands and metal parts, providing a more comfortable hand feel and reducing hand fatigue. The flexible pad can act as a buffer layer between the fixing piece 100, the rotating piece 200 and the locking piece 300 during the locking and releasing process of the buckle assembly, especially in scenarios where better shock resistance is required.
[0043] When the locking piece 300 and the locking rod 1021 are connected together, the flexible pad 103 is arranged opposite and spaced apart from the second base plate, forming a wearing cavity between the rotating piece 200 and the fixed piece 100, which can allow clothes, backpacks and other wearing accessories to pass through.
[0044] When the buckle assembly is in the folded state, the height of the wearing cavity in the third direction ZZ is determined, and in actual cases, in order to improve the scope of application, in the embodiment, referring to Figure 4 , the fixed piece 100 is provided with a flexible pad 103, and the flexible pad 103 is located in the wearing cavity in the folded state.
[0045] The material of the flexible pad 103 and the second flexible pad can be rubber, silicone, sponge, etc. which can be deformed under external force. When placing ropes, belts and other structures of different thicknesses in the wearing cavity, the flexible pad can fit the ropes, belts and other structures, thereby improving the stability of the connection between the buckle assembly and the ropes, belts and other structures of different thicknesses.
[0046] In one implementation, the circumferential surface of the clamping seat 105 is provided with a clamping groove 1051, and the clamping groove 1051 is distributed on the circumferential surface of the clamping seat 105.
[0047] In the embodiment, when the connecting piece is inserted into the clamping groove 1051, the stability in the circumferential direction can be enhanced, preventing loosening or falling off due to vibration or external force, enhancing the connection strength between the clamping seat 105 and other components, and making the overall structure more stable and reliable. Due to the presence of the clamping groove 1051, the connecting piece can be more evenly distributed on the circumferential surface of the clamping seat 105 when stressed, thereby reducing the phenomenon of local stress concentration, which helps to prolong the service life of the connecting piece and the clamping seat 105, and improve the durability of the overall structure.
[0048] Referring to Figure 3 , the fixed piece 100 includes a first base plate, a first mounting portion 104, the rotating piece 200 includes a second base plate, a second mounting portion 202, the first mounting portion 104 and the second mounting portion 202 are connected by a first rotating shaft 101, and the second rotating shaft 201 can be fixed on the first mounting portion 104, or fixed on the second mounting portion 202, or the first mounting portion 104 and the second mounting portion 202 are both sleeved on the second rotating shaft 201.
[0049] When the second rotating shaft 201 is fixed on the first mounting portion 104, the second mounting portion 202 is sleeved on the second rotating shaft 201; when the second rotating shaft 201 is fixed on the second mounting portion 203, the first mounting portion 104 is sleeved on the second rotating shaft 201. When the buckle assembly is in the folded state, the first mounting portion 104 and the second mounting portion 202 are staggered. Under the action of the second rotating shaft 201, the first base plate can rotate relative to the second base plate, so that the entire buckle assembly can switch between the folded state and the unfolded state.
