[0044] Combined with Figures 1 to 6 As shown, an embodiment of the present utility model provides a buckle structure, which is applied to a bicycle derailleur. The bicycle derailleur includes a speed change assembly 100 and a battery assembly 200. The buckle structure includes:

[0045] A buckle main body 10, a protruding member 11 is arranged on one side of the buckle main body 10 close to the speed change assembly 100, and a buckling member 12 is arranged at one end of the buckle main body 10;

[0046] A clamping member 20 is arranged on the side of the battery assembly 200 close to the buckle main body 10;

[0047] A fixing member 30 and a groove 40 are arranged on the side of the speed change assembly 100 close to the buckle main body 10;

[0048] An elastic member 50, one end is arranged on the protruding member 11, and the other end is arranged on the fixing member 30;

[0049] Wherein, the protruding member 11 can be inserted into the groove 40, and the buckling member 12 is clamped on the clamping member 20 to fix the speed change assembly 100 and the battery assembly 200.

[0050] In this embodiment, a protruding member 11 is designed on one side of the buckle body 10 close to the speed change assembly 100 for cooperation with the speed change assembly 100. One end of the buckle body 10 is also provided with a buckle member 12 for fixedly connecting with the battery assembly 200. The clamping member 20 is installed on the side of the battery assembly 200 close to the buckle body 10. The clamping member 20 is used for cooperating and connecting with the buckle member 12 to realize the stable connection between the battery assembly 200 and the buckle body 10. The fixing member 30 and the groove 40 are both arranged on the side of the speed change assembly 100 close to the buckle body 10. The fixing member 30 is used for fixing the elastic member 50, while the groove 40 is used for accommodating the protruding member 11 to increase the stability of the whole buckle structure. One end of the elastic member 50 is fixed on the protruding member 11, and the other end is fixed on the fixing member 30. The function of the elastic member 50 is to provide elastic force, so that the protruding member 11 of the buckle body 10 can automatically lock its position after being inserted into the groove 40, and accumulate elastic restoring force after pulling the protruding member 11 with an external force (specifically, pulling the lower end of the buckle body 10), so as to use the elastic restoring force to make the protruding member 11 automatically insert back into the groove 40 when the external force is released.

[0051] Specifically, when the buckle member 12 is clamped on the clamping member 20, the protruding member 11 is simultaneously inserted into the groove 40. The formed cooperation relationship can firmly connect the speed change assembly 100 and the battery assembly 200 together. This not only ensures the stability of the connection, but also simplifies the installation and disassembly process and improves the use convenience. In addition, the elastic member 50 enables the whole buckle structure to have a certain elastic restoring force when subjected to an external force. The buckle body 10 and the elastic member 50 are connected to the speed change assembly 100 and the battery assembly 200 in a manner similar to a connecting rod. The battery assembly 200 is clamped on the speed change assembly 100 under the pressing of the buckle body 10. After being in the correct position, the angle of the elastic member 50 will form a self-locking angle and will not open by itself in the natural state. Only by using an external force to pull the protruding member 11 can the locking state between the speed change assembly 100 and the battery assembly 200 be released.

[0052] In one embodiment, the buckle member 12 bends downward to form an arc-shaped groove 13 with the buckle body 10. The outer side of the clamping member 20 protrudes upward to form an arc-shaped portion 21. A buckle groove 22 is formed between the arc-shaped portion 21 and the battery assembly 200. The arc-shaped groove 13 is clamped outside the arc-shaped portion 21 and can move relative to the arc-shaped portion 21. The buckle member 12 is clamped in the buckle groove 22 and can move relative to the buckle groove 22.

[0053] In this embodiment, the buckle 12 is designed to be bent downward, and an arc groove 13 is formed between the buckle body 10. The outer side of the clamping member 20 is designed as an arc portion 21 protruding upward, and a buckle groove 22 is formed between the battery assembly 200. Specifically, the arc groove 13 is clamped to the outer side of the arc portion 21 to form a buckle structure, and the buckle 12 is clamped in the buckle groove 22 to form another buckle structure, so that the upper end of the buckle body 10 is buckled with the battery assembly 200 through two buckle structures, thereby improving the stability of the buckle. At the same time, since the arc groove 13 can move relative to the arc portion 21, specifically, the arc groove 13 is set downward and the arc portion 21 is set upward, so when the lower end of the buckle body 10 is pulled open, the arc groove 13 can move in a direction away from the arc portion 21. The buckle 12 is arranged downward and the buckle groove 22 is arranged upward, so when the lower end of the buckle body 10 is pulled open, the buckle 12 will rotate with the buckle groove 22 as the rotation center, so when the lower end of the buckle body 10 is pulled open, the entire buckle body 10 will rotate with the buckle groove 22 as the rotation center, thereby releasing the locked state of the battery assembly 200 and the transmission assembly 100, and then the holding member 20 of the battery assembly 200 is separated from the buckle 12, and the battery assembly 200 can be removed. When installing the battery assembly 200, the lower end of the buckle body 10 can also be pulled open, and then the holding member 20 of the battery assembly 200 is connected to the buckle 12, and then the lower end of the buckle body 10 is released, and the elastic restoring force of the elastic member 50 is used to automatically insert the lower end (protruding member 11) of the buckle body 10 back into the groove 40.

[0054] The buckle structure of this embodiment effectively solves the shortcomings of the traditional fixing method in terms of operational convenience and connection stability, which not only improves the overall assembly efficiency but also enhances the reliability and durability of the buckle structure in long-term use.

[0055] In one embodiment, the battery assembly 200 is disposed above the transmission assembly 100 , and the clamping member 20 is located above the fixing member 30 .

[0056] In this embodiment, the battery assembly 200 is arranged above the shift assembly 100. This up-and-down arrangement helps to better utilize the vertical space of the bicycle derailleur, thereby increasing safety during use. The clamping member 20 is located above the fixing member 30. This layout allows the clamping member 20 to be directly connected to the battery assembly 200 and cooperate with the fixing member 30 to provide additional support.

[0057] In one embodiment, the fixing member 30 is located above the groove 40 , the fixing member 30 is tilted upward, and the other end of the elastic member 50 is disposed on the top of the fixing member 30 .

[0058] In this embodiment, the upward tilted structural design of the fixing member 30 not only enhances the bonding strength between the fixing member 30 and the adjacent clamping member 20, but also provides a relatively ideal support point for installing the elastic member 50, so that the elastic member 50 can play a more effective role. The main function of the groove 40 is to cooperate with other structural members (such as the protruding member 11) to provide a stable engagement position, thereby enhancing the fixing effect of the entire buckle structure. The groove 40 located below the fixing member 30 helps to form a tight and efficient locking position, ensuring that the buckle body 10 and the fixing member 30 are not prone to loosening. One end of the elastic member 50 is arranged on the protruding member 11, and the other end is fixed to the top of the fixing member 30, which enables the elastic member 50 to provide tension between the buckle body 10 and the speed change assembly 100, which is conducive to absorbing and alleviating the vibration and impact generated by the bicycle movement.

[0059] Combination Figures 7 to 10 As shown, in one embodiment, after the protruding member 11 is inserted into the groove 40, the connecting line of the two ends of the elastic member 50 is inclined relative to the vertical line.

[0060] In this embodiment, when the protrusion 11 is inserted into the groove 40 (i.e., in the self-locking state), the configuration angle of the elastic member 50 generates prestress, thereby maintaining a certain tension in the connected state. By setting it in an inclined manner, the elastic member 50 can provide additional elastic force, which helps to reduce the impact force caused by movement and keep the buckle body 10 in the self-locking state. In addition, this design also allows the buckle structure to be unlocked or locked by adjusting the pressure during disassembly and assembly, making installation and maintenance easier and faster. Figure 8 From the perspective of FIG. 1 , with the vertical direction of the buckle body 10 as a reference vertical line, in the locked state, the line connecting the two ends of the elastic member 50 is shown as gradually tilted relative to the vertical line.

[0061] Combination Figure 11 As shown, in one embodiment, one end of the elastic member 50 is fixedly disposed on the protruding member 11 , and the other end is rotatably disposed on the fixing member 30 .

[0062] In this embodiment, the other end of the elastic member 50 is rotatably set on the fixing member 30. This rotational setting allows the elastic member 50 to have a certain degree of freedom of movement outside the fixed point, so that during the installation and removal of the battery assembly 200, one end of the elastic member 50 is fixed in the protrusion 11 and does not move with the movement of the buckle body 10, while the other end of the elastic member 50 is rotatably set on the fixing member 30 and rotates with the rotation of the buckle body 10.

[0063] Combination Figure 12As shown, in one embodiment, the elastic member 50 includes two elastic portions 51. One end of each of the two elastic portions 51 is fixedly provided on both sides of the protruding member 11, and the other end of each of the two elastic portions 51 is rotatably provided on both sides of the fixing member 30.

[0064] In this embodiment, the two elastic portions 51 are symmetrically arranged, and one end of each of the two elastic portions 51 is fixedly provided on both sides of the protruding member 11. The protruding member 11 is usually matched with the groove 40 to provide a locking point to ensure the tightness of the connection. The other end of each of the two elastic portions 51 is rotatably provided on both sides of the fixing member 30. This structure can improve the balance on both sides when the buckle body 10 rotates and enhance the rotation stability.

[0065] In one embodiment, the other end of the buckle body 10 is arranged towards the side away from the speed change assembly 100 to form a trigger notch 14.

[0066] In this embodiment, the setting of the trigger notch 14 facilitates the user's operation when unlocking or adjusting the buckle structure, so as to quickly and safely complete the opening or closing of the buckle body 10. The user can quickly adjust or unlock the buckle body 10 in different usage scenarios.

[0067] Combined with Figure 13 As shown, the present utility model also provides a bicycle derailleur, which includes a speed change assembly 100, a battery assembly 200, and the buckle structure as described above. The battery assembly 200 is connected to the speed change assembly 100 through the buckle structure.

[0068] In this embodiment, the speed change assembly 100 is a core functional component in the bicycle derailleur, responsible for realizing speed changes at different levels. The battery assembly 200 provides the required power for the speed change assembly 100 to ensure its normal operation. The buckle structure is used to connect the battery assembly 200 to the speed change assembly 100. Through the buckle structure designed by the present utility model, the stability and reliability of the connection are ensured, preventing the battery assembly 200 from loosening or falling off in a complex riding environment. The design of the buckle structure also allows the user to quickly and easily perform maintenance and replacement of the battery assembly 200.

[0069] The present utility model also provides a bicycle, which includes the bicycle derailleur as described above.

[0070] In this embodiment, the bicycle can be equipped with a bicycle derailleur with a buckle structure, providing a more efficient, safer, and more convenient riding option for riders.

[0071] The above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
