DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0025] The same or similar reference signs in the drawings of the embodiments correspond to the same or similar components; in the description of the present application, it should be understood that the orientations or position relationships indicated by the terms "upper", "lower", "left", "right" and the like are based on the orientations or position relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and are not indicative or suggestive of the devices or elements indicated having a particular orientation, being constructed and operated in a particular orientation, therefore the terms describing the position relationships in the drawings are only used for exemplary illustration, and cannot be understood as a limitation of the present patent, for those skilled in the art, the specific meanings of the above terms can be understood according to the specific circumstances.

[0026] Reference is made to Figures 1-9The buckle assembly provided by the embodiment of the present disclosure comprises a fixing member 100 and a clamping member 200. The fixing member 100 is formed with a clamping groove 101. The clamping groove 101 is provided with a limiting tooth 102 and two elastic members 103. The limiting tooth 102 and the elastic member 103 are distributed on the circumferential surface of the clamping groove 101. The outer periphery of the clamping member 200 is provided with a limiting groove 201 and two positioning grooves 202. The limiting groove 201 and the positioning groove 202 are distributed on the circumferential surface of the clamping member 200. When the limiting groove 201 on the clamping member 200 and the limiting tooth 102 on the fixing member 100 are in an abutting state, the elastic member 103 of the fixing member 100 is at least partially located in the positioning groove 202 on the clamping member 200. When the clamping member 200 rotates in the clamping groove 101, the elastic member 103 of the fixing member 100 is separated from the positioning groove 202 on the clamping member 200.

[0027] In actual application, the number of the limiting tooth 102 can be one, two or more. The number of the limiting groove 201 is consistent with the number of the limiting tooth 102. The limiting tooth 102 is made of a material with certain elasticity, such as plastic, rubber or silica gel. The limiting tooth 102 has good deformation recovery ability and can maintain stable performance in long-term use. When the limiting tooth 102 is located in the limiting groove 201, the rotation of the fixing member 100 relative to the clamping member 200 will have additional resistance. Therefore, the fixing member 100 and the clamping member 200 are difficult to rotate relative to each other when they are in the clamped state, which reduces the possibility of the clamping block 1031 sliding out of the positioning groove 202 and enhances the stability of the fixing member 100 and the clamping member 200 in the clamped state.

[0028] In the embodiment, the interaction between the limiting tooth on the fixing member and the limiting groove on the clamping member ensures that the clamping member can be accurately positioned and smoothly inserted into the clamping groove during installation. When the elastic member is at least partially located in the positioning groove on the clamping member, a certain pre-tightening force is provided to prevent the clamping member from accidentally falling off when it is not subjected to external force, thereby realizing stable and reliable connection. In actual application, the user can rotate the clamping member to separate the elastic member on the fixing member from the positioning groove on the clamping member. The use of the elastic member not only increases the stability of the connection, but also absorbs and alleviates the impact and vibration caused by external force to a certain extent.

[0029] Referring to Figures 1-9 The clamping member 200 and the fixing member 100 form a clamping structure. The fixing member 100 is formed with a clamping groove 101 having a bottom wall 1011 and a side wall 1012. The clamping member 200 is at least partially located in the fixing member 100 and connected to the fixing member 100. The clamping member 200 can rotate relative to the fixing member 100, and the clamping member 200 is at least partially located in the clamping groove 101.

[0030] When the clamping piece 200 and the fixing piece 100 are in a disengaged state, the elastic piece 103 is retracted into the fixing piece 100, and the restriction on the clamping seat 203 is released. Through the cooperation between the clamping groove 101 of the fixing piece 100 and the clamping seat 203 of the clamping piece 200, and the close cooperation between the positioning groove 202 and the elastic piece 103, the accidental falling of the fixing piece 100 during wearing can be prevented.

[0031] In an implementation manner, referring to Figures 1-9 , the shape of the clamping piece 200 and the shape of the clamping groove 101 are matched, and the two elastic pieces 103 are centrally symmetrically distributed on the circumferential surface of the clamping groove 101.

[0032] In this embodiment, the shape of the clamping piece and the shape of the clamping groove are matched, so that the clamping piece can be accurately inserted into the clamping groove, reducing the misplacement and shaking during installation. At the same time, the two elastic pieces which are centrally symmetrically distributed can provide uniform pre-tightening force from both sides after the clamping piece is completely inserted, further enhancing the stability of the connection and preventing accidental loosening or falling of the clamping piece during use.

[0033] It should be understood that the plurality of elastic pieces 103 are uniformly distributed along the side wall 1012 of the clamping groove 101, so that the stress of the entire fixing piece 100 is balanced, enhancing the stability of the clamping piece 200 and the fixing piece 100 when clamped. In the example, the number of positioning grooves 202 on the clamping seat 203 is consistent with the number of elastic pieces 103, and one-to-one correspondence is achieved. When each elastic piece 103 corresponding positioning groove 202 is correctly inserted, accidental falling of the fixing piece 100 due to shaking or impact during wearing or use is prevented, ensuring accurate alignment of the fixing piece 100 and the clamping piece 200 when connected, enhancing the stability of the connection, and reducing stress concentration and wear caused by misplacement.

[0034] Referring to Figures 1-9 , the clamping piece 200 further comprises a back clip assembly 205 connected to the clamping seat 203. The back clip assembly 205 can be a back clip fixed on a waistband, or a buckle belt installed on a backpack shoulder strap, or a helmet support installed on a helmet, etc.

[0035] In an implementation manner, referring to Figures 1-9 , the circumferential surface of the clamping groove 101 is provided with a guide groove 1033; the fixed end of the elastic piece 103 is connected to the fixing piece 100, the free end of the elastic piece 103 is arranged in the guide groove 1033, and the free end of the elastic piece 103 is at least partially located in the guide groove 1033.

[0036] In this embodiment, the guide groove provides a clear movement path for the free end of the elastic piece, ensuring that the elastic piece can move along the predetermined trajectory during the insertion and rotation of the clamping piece, avoiding the problems of jamming or damage caused by poor movement of the elastic piece.

[0037] In practical applications, the free end of the elastic member is restricted to move within the guide groove, effectively preventing the elastic member from deviating or twisting during force application. Even in the case of external force impact or vibration, the elastic member can maintain its original functional characteristics, ensuring the continuity and effectiveness of the connection. The combination of the guide groove and the elastic member makes the buckle assembly more compact in structure.

[0038] In this embodiment, during the insertion or rotation of the clamping member, the free end of the elastic member moves along the guide groove, reducing the resistance caused by friction or misalignment. The free end of the elastic member is restricted to move within the guide groove, which helps to optimize the force distribution. During the connection of the clamping member and the fixed member, the elastic member can uniformly bear and transmit force, avoiding local stress concentration and damage caused by uneven force.

[0039] Referring to Figures 1-9 , the fixed member 100 is provided with a guide groove 1033 having two limiting walls opposite in the first direction XX. The elastic body 1032 and the clamping block 1031 protrude into the guide groove 103, and at least part of the clamping block 1031 abuts against the two limiting walls. The first direction XX is perpendicular to the direction YY of the rotation axis of the fixed member 100. The presence of the limiting wall provides a guide path for the clamping block 1031, allowing the clamping block 1031 to move in a predetermined direction, avoiding unnecessary deviation or shaking, and improving the stability of the connection between the fixed member 100 and the clamping member 200.

[0040] In one implementation, referring to Figures 1-9 , the elastic member 103 includes a clamping block 1031 and an elastic body 1032. The first end of the elastic body 1032 and the bottom of the guide groove 1033 are in elastic contact, and the second end of the elastic body 1032 and the clamping block 1031 are in elastic contact. The opening of the guide groove 1033 forms a limiting portion, which limits the clamping block 1031 in the direction of the elastic force of the elastic body 1032.

[0041] In this embodiment, the first end of the elastic body is in elastic contact with the bottom of the guide groove, and the second end is in elastic contact with the clamping block, so that the elastic body can be uniformly stressed when subjected to external force, and the position and state of the clamping block can be accurately controlled through its elastic deformation. The limiting portion formed by the opening of the limiting groove limits the clamping block in the direction of the elastic force of the elastic body. This ensures the stability and accuracy of the clamping block during movement, preventing damage or connection failure caused by excessive movement.

[0042] In practical applications, the presence of the elastic body allows the clamping block to be effectively buffered and supported when under stress, reducing the impact and vibration caused by direct stress. This helps to maintain the stability and reliability of the connection. The limiting portion can limit the movement range of the clamping block, preventing it from accidentally falling out or loosening during the connection process.

[0043] Referring to Figures 1-9 , the elastic member 103 includes a clamping block 1031 and an elastic body 1032. The clamping block 1031 passes through the side wall 1012 of the clamping groove 101 and is at least partially located in the clamping groove 101 under the action of the elastic body 1032. The elastic member 103 is clamped in the positioning groove 202 and is not easily detached from the positioning groove 202 after being clamped in the positioning groove 202.

[0044] Referring to Figures 1-9 , the elastic body 1032 has a compressed state and an expanded state. In the compressed state, the elastic body 1032 is located in the fixed member 100, and in the transition from the compressed state to the expanded state, the elastic body 1032 can be partially accommodated in the clamping groove 101. Due to the presence of the elastic body 1032, the clamping member 200 passes through the side wall 1012 of the clamping groove and enters the positioning groove 202 under the action of a small external force applied by the user. This rapid clamping feature improves assembly efficiency, and because of the elastic force of the elastic body 1032, the clamping block 1031 is not easily detached from the positioning groove 202, enhancing the stability of the fixed member 100 and the clamping member 200 in the clamped state.

[0045] In one implementation, referring to Figures 1-9 , the fixed member 100 includes a cover 105 and a base 106. The cover 105 forms the clamping groove 101. The base 106 includes a mounting plate 1061 and a raised portion 1062. The mounting plate 1061 is located in the cover and is mounted to the cover. The raised portion 1062 is mounted to the mounting plate 1061 and protrudes towards the clamping groove 101. The surface of the raised portion 1062 away from the mounting plate 1061 forms the bottom wall 1011 of the clamping groove 101. The clamping member is provided with a positioning hole 206 on the side facing the raised portion 1062. The raised portion 1062 and the positioning hole 206 are shaped to match, and the raised portion 1062 is accommodated in the positioning hole 206 when the fixed member 100 and the clamping member 200 are in the clamped state.

[0046] In this embodiment, the fixing member is designed as two main parts, the cover and the base, the base is fixed in the cover through the mounting plate, and the raised part is raised towards the clamping groove, forming a compact internal structure. The surface of the raised part away from the mounting plate constitutes the bottom wall 1011 of the clamping groove, which can increase the strength and rigidity of the bottom wall 1011. When the clamping member is connected with the fixing member, the bottom wall 1011 can provide better support and stability, preventing deformation or damage due to uneven stress. Due to the presence of the raised part, the clamping member can be more easily and accurately docked when inserted into the clamping groove, reducing connection problems caused by misalignment or excessive gap. The fixing member can better disperse and absorb impact energy when subjected to external force impact.

[0047] Referring to Figures 1-9 , the fixing member 100 includes a cover 105 and a base 106, the cover 105 forms a clamping groove 101, and the base 106 includes a mounting plate 1061 and a raised part 1062, the mounting plate 1061 is located in the cover 105 and mounted on the cover 105, the cover 105 protects the mounting plate 1061 and electronic components mounted on the mounting plate 1061, improving the ability to resist external impact and vibration.

[0048] Referring to Figures 1-9 , the raised part 1062 is located on the mounting plate 1061 and raised towards the clamping groove 101, the surface of the raised part 1062 away from the mounting plate 1061 forms the bottom wall 1011 of the clamping groove, and the raised part 1062 effectively utilizes the space inside the cover 105, making the volume of the entire fixing member 100 more compact. In addition, the raised part 1062 can be used as part of the heat dissipation to conduct the heat generated inside the fixing member 100 to the external environment, improving the heat dissipation performance of the device.

[0049] In one implementation, referring to Figures 1-9 , the fixing member 100 further includes a first magnetic attraction member 104, and the clamping member 200 further includes a second magnetic attraction member 204, the first magnetic attraction member 104 and the second magnetic attraction member 204 are oppositely arranged.

[0050] In this embodiment, the first magnetic attraction member and the second magnetic attraction member can be quickly and accurately attracted and connected together by the attraction of magnetic force. In actual application, the user only needs to bring the clamping member close to the fixing member, and the two can be automatically adsorbed and connected without the need for additional tools or complex operation steps. The magnetic attraction connection maintains the stability of the connection through the magnetic force, and even when subjected to a certain external force, it can maintain the tightness of the connection. This stable connection helps to reduce failures and damage caused by loosening or falling off.

[0051] Referring to Figures 1-9In order to improve the stability of the fixed part 100 and the clamping part 200 in the clamping state and reduce the possibility of separation of the fixed part 100 and the clamping part 200, in the embodiment, the fixed part 100 further comprises a first magnetic attraction part 104 arranged in the fixed part 100, and the clamping part 200 further comprises a second magnetic attraction part 203 arranged in the interior of the clamping seat 203, the first magnetic attraction part 104 and the second magnetic attraction part 203 are magnetically different, and a magnetic attraction force is formed between the first magnetic attraction part 104 and the second magnetic attraction part 203 when the clamping seat 203 is installed in the clamping groove 101.

[0052] Referring to Figures 1-9 The magnetic attraction force formed by the first magnetic attraction part 104 and the second magnetic attraction part 203 makes the connection between the fixed part 100 and the clamping part 200 more stable, and when subjected to external force impact or vibration, the magnetic force can effectively resist the separation trend and maintain the stability of the connection. When disassembly is required, the user only needs to slightly overcome the magnetic force to achieve quick separation.

[0053] Referring to Figures 1-9 In order to improve the attraction force of the first magnetic attraction part 104 and the second magnetic attraction part 203, the first magnetic attraction part 104 is arranged close to the clamping groove 101, and the first magnetic attraction part 104 can be installed in the raised portion 1062. When the clamping seat 203 is located in the clamping groove 101, the distance between the first magnetic attraction part 104 and the second magnetic attraction part 203 is relatively close, a magnetic attraction force is formed therebetween, and the stability of the connection between the fixed part 100 and the clamping part 200 is improved.

[0054] In an implementation manner, referring to Figures 1-9 Along the rotation direction of the clamping part 200, the opening of the limiting groove 201 forms an inclined surface, and the opening of the positioning groove 202 forms an inclined surface; along the radial direction of the clamping groove 101, the opening of the limiting groove 201 gradually shrinks, and the opening of the positioning groove 202 gradually shrinks.

[0055] In the embodiment, the openings of the limiting groove and the positioning groove form inclined surfaces, which play a smooth guiding role in the process of insertion or rotation of the clamping part. The inclined surfaces can gradually guide the clamping part into the correct position, reduce the resistance and impact caused by direct collision, and realize accurate positioning of the clamping part. When the clamping part is completely in place, it can be accurately locked in the limiting groove and the positioning groove to prevent loosening or mispositioning. Along the radial direction of the clamping groove, the openings of the limiting groove and the positioning groove gradually shrink, so that the clamping part is inserted and locked in the groove and is not easy to loosen or fall off due to external force, thereby improving the reliability of the connection.

[0056] Referring to Figures 1-9, the clamping block 1031 has a top wall along the depth direction of the clamping groove 101, along the direction from the center of the clamping groove 101 to the side wall 1012 of the clamping groove, the distance between the top wall and the slot of the clamping groove 101 gradually decreases, during the clamping process of the fixing part 100 and the clamping part 200, the clamping seat 203 extends into the clamping groove 101, the gradually changing distance between the top wall of the clamping block 1031 and the slot of the clamping groove 101, when the clamping seat 203 contacts the clamping block 1031, the clamping block 1031 retracts into the fixing part 100, until the clamping seat 203 extends into the positioning groove 202 opposite to the clamping block 1031, achieving the quick installation of the fixing part 100 and the clamping part 200. In order for the clamping block 1031 to retract smoothly into the fixing part 100, the top wall of the clamping block 1031 adopts a gradually changing inclined surface or a curved shape to smoothly transition the distance change between the top wall and the slot.

[0057] In an implementation manner, referring to Figures 1-9 , the clamping part 200 includes a clamping seat and a back clip, the clamping seat is provided with a limiting groove and a positioning groove on its circumferential surface; the first end surface of the clamping seat faces the clamping groove 101, and the second end surface of the clamping seat is connected to the fixed end of the back clip.

[0058] In this embodiment, the limiting groove and the positioning groove on the clamping seat cooperate with the corresponding structures on the fixing part to achieve stable fixation of the clamping part in the circumferential direction. In actual application, the limiting groove and the positioning groove on the clamping seat have a guiding effect, making it easier to find the correct position and smoothly insert the clamping part during installation. At the same time, the fixed end of the back clip is connected to the second end surface of the clamping seat, providing additional stability and directionality for installation. When the clamping part needs to be disassembled, through appropriate operations (such as rotation, pressing, etc.), the clamping part can be easily detached from the fixing part without the need for complex tools or cumbersome steps.

[0059] Referring to Figures 1-9 , the clamping part 200 includes a clamping seat 203, the clamping seat 203 is adapted to the clamping groove 101, the side wall 1012 of the clamping groove is provided with a positioning groove 202, the positioning groove 202 on the clamping part 200 forms a clamping with the elastic part 103 on the fixing part to limit the clamping seat 203 from falling off the clamping groove 101. When the clamping part 200 and the fixing part 100 are in a clamped state, the clamping seat 203 is placed in the clamping groove 101, the clamping seat 203 is limited by the bottom wall 1011 of the clamping groove 101, the elastic part 103 extends into the positioning groove 202 of the clamping seat 203 through the side wall 1012 of the clamping groove 101, limiting the clamping seat 203 from falling off the clamping groove 101.

[0060] Referring to Figures 1-9 Figures 1-9The fixing member 100 further comprises a limiting tooth 102 which is deformed under external force. The limiting tooth 102 is arranged on the side wall 1012 of the clamping groove. The side wall 1012 of the clamping groove is provided with a limiting groove 201. The limiting groove 201 is formed with a guide opening on the side of the clamping seat 203 facing the clamping groove 101. When the clamping seat 203 is installed in the clamping groove 101, the limiting tooth 102 extends into the limiting groove 201 along the corresponding guide opening. When the limiting tooth 102 extends into the limiting groove 201, the limiting tooth 102 contacts the two side walls 1012 opposite to the clamping seat 203 in the circumferential direction, so that the limiting tooth 102 is tightly matched with the limiting groove 201, and the stability of the fixing member 100 and the clamping member 200 in the clamped state is enhanced,
