Description

Technical Field

[0001] This utility model relates to a folding bicycle, specifically to a locking structure for a folding bicycle. Background Technology

[0002] Most folding bicycles currently on the market use a locking structure where a latch and a locking lever engage between the frames. This locking mechanism is typically fixed and cannot be adjusted for extension or retraction. When the first and second frames are folded into place, manual pressing or alignment is required to ensure the latch and locking lever are properly aligned before the bicycle can be locked. This method has the following drawbacks in practical use:

[0003] First, because the locking mechanism cannot extend or retract, users often need to repeatedly adjust the position or squeeze it forcefully when folding the frame, which is cumbersome and affects folding efficiency and ease of use.

[0004] Secondly, traditional structures rely solely on the engagement of the latch and the locking rod to maintain the folded state after locking, lacking an effective axial limiting function. During vehicle use or transport, vibration or impact can easily cause the latch and the locking rod to separate, resulting in the lock coming loose and posing a safety hazard of the frame unexpectedly unfolding. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a folding bicycle locking structure that balances ease of operation with reliable axial limiting capability, effectively overcoming the shortcomings of existing technologies.

[0006] This utility model is achieved through the following technical solution: a folding bicycle locking structure, comprising:

[0007] A first frame and a second frame, wherein the first frame and the second frame are foldable together;

[0008] A locking element is movably mounted on the first frame or the second frame. When the first frame and the second frame are folded together, the locking element locks the first frame and the second frame together to maintain the folded state.

[0009] The locking component is a telescopic locking component with a snap-in groove. A locking rod is provided on the first or second vehicle frame, and the locking component is fastened to the locking rod through the snap-in groove.

[0010] The locking member is also provided with a safety element, which locks the extension length of the locking member and restricts the degree of freedom of the locking member in the axial direction of the locking rod.

[0011] As a preferred technical solution, the locking component includes a main body, one end of which is provided with a pull-out cavity, a fixing part is telescopically inserted into the pull-out cavity, the snap-in groove is provided on the fixing part, the safety component is rotatably provided on the main body, and one end of the main body is rotatably provided on the first frame or the second frame via a rotating pin.

[0012] As a preferred technical solution, one end of the safety component is provided with a locking pin, the locking pin is provided with external threads, the safety component is provided with a threaded locking hole, the locking pin is threaded into the threaded locking hole, and the side of the locking pin facing the fixing part is provided with an elastic locking part.

[0013] As a preferred technical solution, the elastic locking part is made of elastic rubber material, and the elastic locking part contacts and locks with the telescopic fixing part. When the snap-in slot is installed on the locking rod, the elastic locking part presses against the fixing part.

[0014] As a preferred technical solution, the other end of the safety component is provided with a slide groove, and an axial limiting component is provided in the slide groove. The axial limiting component can slide left and right in the slide groove. A knob is provided on the outer side of the axial limiting component, and a connector is provided on the inner side of the axial limiting component.

[0015] As a preferred technical solution, the outer surface of the connector is provided with an external thread, the locking rod has a threaded connection hole, and the connector thread is turned into the threaded connection hole.

[0016] The beneficial effects of this utility model are as follows: By providing a retractable fixing part and a snap-fit ​​groove on the locking part, the locking part can extend and retract during folding, eliminating the need for repeated squeezing or forced alignment by the user, greatly simplifying the folding operation and improving the convenience and efficiency of folding. Through the cooperation of the safety part and the retractable fixing part, the extended length of the locking part can be locked, effectively preventing accidental retraction due to external force and enhancing the stability of the locked state.

[0017] At the same time, by using the threaded connection of the connector head to lock into the threaded connection hole of the locking rod, the safety component can effectively limit the axial movement of the entire locking component, prevent the locking component from separating from the locking rod axially, and make the positioning effect better, effectively preventing the two frames from unfolding.

[0026] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0027] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0028] like Figures 1-5As shown, the folding bicycle locking structure of this utility model includes a first frame 2 and a second frame 3, which can be folded together to allow for flexible switching between use and storage of the vehicle. In the folded state, to ensure reliable locking of the two frames, a locking element 1 is provided in the structure, which is movably installed on either the first frame 2 or the second frame 3. When the first frame 2 and the second frame 3 are folded into place, the locking element 1 can cooperate with the locking rod 103 provided on the frame to stably lock the two frames in the folded state, thereby preventing the frames from unfolding due to external forces.

[0029] The locking member 1 adopts a telescopic structure, and a snap-in groove 102 is formed on the locking member 1. The locking rod 103 is fixed at the corresponding position of the first frame 2 or the second frame 3.

[0030] Through the telescopic action, the locking member 1 can freely extend or retract along its installation direction. During the folding process, by stretching the locking member 1, the snap-in slot 102 can be automatically snapped onto the locking rod 103. Users do not need to repeatedly adjust the folding spacing or align the snap-in slot and the locking rod 103 through additional squeezing action, thus significantly improving the convenience of operation.

[0031] To further improve the reliability of the locking mechanism, a safety element 104 is also provided on the locking member 1. The function of the safety element 104 is to control the position of the locking member 1 by the length of the locking telescopic part, and at the same time restrict the degree of freedom of the locking member 1 in the axial direction of the locking rod 103, thereby preventing the locking member 1 from accidentally disengaging due to vibration or impact.

[0032] Specifically, the locking member 1 includes a main body 101, one end of which is provided with a pull-out cavity, and a fixing part 109 is telescopically inserted into the pull-out cavity.

[0033] The snap-in groove 102 is formed on the fixing part 109, so that when the fixing part 109 is extended or retracted, the snap-in groove 102 can be extended to a suitable position to be fastened with the locking rod 103. The safety element 104 is rotatably mounted on the main body 101. One end of the main body 101 is rotatably connected to the first frame 2 or the second frame 3 through a rotating pin, so that the overall structure is stable and has a certain degree of freedom.

[0034] A locking pin 1041 is formed at one end of the safety element 104. The outer surface of the locking pin 1041 is provided with external threads, and the body of the safety element 104 is provided with a threaded locking hole. The locking pin 1041 can be threaded into the threaded locking hole. An elastic locking part 1045 is provided on the side of the locking pin 1041 facing the fixing part 109. The elastic locking part 1045 is made of elastic rubber material and can undergo elastic deformation during the locking process.

[0035] When the snap-in slot 102 is fastened onto the locking rod 103, the elastic locking part 1045 will press against the fixing part 109, thereby allowing the safety part 104 to have greater freedom of circumferential rotation when the locking pin 1041 is tightened. The fixing part 109 is pressed against by elastic compression, ensuring that the locking part 1 does not loosen after being fastened.

[0036] At the other end of the safety component 104, a groove 1042 is formed, and an axial limiting component 1043 is slidably disposed inside the groove 1042. The axial limiting component 1043 can move left and right within the groove 1042. A knob 1044 is designed on its outer side for easy manual operation by the user, while a connector 1046 is provided on its inner side.

[0037] The outer surface of the connector 1046 is machined with external threads, and the locking rod 103 is correspondingly provided with a threaded connection hole. After the locking operation is completed, the user can rotate the knob 1044 to slide and adjust the position of the axial limiting member 1043, so that the connector 1046 is aligned with the threaded connection hole of the locking rod 103. Then, by rotating, the thread of the connector 1046 is turned into the threaded connection hole, thereby completing the final locking action. This structure not only realizes the engagement of the locking member 1 and the locking rod 103, but also further strengthens the axial limiting capability through the threaded connection, effectively preventing the lock from loosening due to vibration or impact during vehicle use.

[0038] When the user folds the first frame 2 and the second frame 3, there is no need to deliberately control the folding gap. Simply stretching the locking member 1 will allow the snap-in slot 102 to snap onto the locking rod 103. After snapping, rotate the safety member 104 so that the connector 1046 is screwed into the threaded connection hole of the locking rod 103. Finally, the axial limiting member 1043 slides along the slide groove 1042 to find the corresponding position of the locking rod 103 and completes the locking.

[0039] The process is simple to operate and has a stable structure. The elastic clamping effect of the elastic locking part 1045 can improve the locking effect. At the same time, the threaded connection and limit design effectively improve the vibration resistance and anti-loosening performance, ensuring the safety and reliability of the folding bike during use and carrying.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
