Technical Field
[0001] This utility model relates to the technical field of scooters, and more particularly to a folding structure for scooters. Background Technology
[0002] A scooter is a convenient mode of transportation, mainly consisting of a footboard and a handlebar stem. The handlebar stem can be folded and stored on the footboard for easy storage or transport. In existing scooter technology, the handlebar stem is usually locked with a locking nut. However, when riding on bumpy roads, the nut can easily fall off the handlebar stem due to vibration, affecting the user's riding safety. At the same time, when folding the handlebar stem for storage or unfolding it for use, the locking nut needs to be turned repeatedly, which is inconvenient and affects the convenience of use. This needs to be improved. Summary of the Invention
[0003] This utility model addresses the shortcomings of existing scooter technology, such as the use of locking nuts to lock the handlebar stems, which makes folding or unfolding the handlebar stems inconvenient and the locking nuts easily falling off the handlebar stems due to vibration during riding, thus affecting riding safety. It provides a new scooter folding structure.
[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0005] A folding structure for a scooter includes a stem and a folding base. The folding base includes a fixed part and a rotating part. The stem is connected to the rotating part. The structure also includes a folding lever rotatably mounted on the fixed part and a safety buckle slidably mounted inside the stem. One side of the safety buckle protrudes from the stem. The stem has a locking hole that faces one end of the safety buckle. The folding lever has a rotatably mounted locking buckle. The folding lever drives the locking buckle to rotate toward or away from the locking hole.
[0006] The riser, folding wrench, and safety buckle are in a locked and unlocked state. In the locked state, the folding wrench is folded to the riser, the locking buckle is locked in the locking hole, and one end of the safety buckle is inserted into the locking hole and prevents the locking buckle from turning out of the locking hole. In the unlocked state, the safety buckle moves into the riser, the locking buckle is withdrawn from the locking hole, and the folding wrench unfolds away from the riser.
[0007] The safety buckle limits the locking mechanism, improving the locking effect on the stem in the locked state and preventing accidental unlocking of the stem, thus enhancing riding safety. To unlock, simply press the safety buckle inward and rotate it to fold and store the stem. To use the stem, simply rotate the folding lever towards the stem and fold it in place to lock the stem in the locking hole. This allows for quick locking and unlocking of the stem, improving ease of operation and convenience.
[0008] Preferably, in the above-described scooter folding structure, the safety buckle includes a buckle plate with elastic deformation capability and a return spring. The buckle plate has a button that extends through the riser tube. One end of the buckle plate has an abutment block that faces the locking hole. The other end of the buckle plate abuts against the inner wall of the riser tube. One end of the return spring abuts against the inner wall of the riser tube, and the other end of the return spring is connected to the buckle plate and pushes the abutment block into the locking hole. In the locked state, the abutment block abuts against the outside of the locking buckle and interferes with the locking buckle rotating out of the locking hole.
[0009] In the locked state, the abutment block located outside the locking buckle can interfere when the locking buckle is withdrawn from the locking hole. This design can effectively prevent the riser from being accidentally folded due to vibration during use. The buckle provides a force application position for the user's hand, making it easy for the user to switch the safety buckle to the unlocked state. The two ends of the buckle plate with elastic deformation capability are respectively pressed against the opposite inner walls of the riser, so that the force on the buckle plate can be evenly distributed, improving the stability of the safety buckle when subjected to impact. The presence of the return spring allows the buckle plate to automatically return to its original position, reducing the user's operation steps and further improving the convenience of locking and unlocking the riser.
[0010] Preferably, in the folding structure of the scooter described above, the folding lever has a movable notch, the lower end of the locking buckle is rotatably disposed in the movable notch, the upper end of the locking buckle protrudes from the movable notch, a pressing spring is disposed in the movable notch, one end of the pressing spring is connected to the inner wall of the movable notch, the other end of the pressing spring is connected to the locking buckle, and the pressing spring pushes the locking buckle to rotate outward from the folding lever.
[0011] The pressing spring applies a spring force to the locking buckle to pull it out of the locking hole, making it easy to rotate the locking buckle out of the locking hole. At the same time, the pressing spring increases the force between the abutment block and the locking buckle when they are locked, which can effectively prevent the locking buckle from falling out of the locking hole and improve the stability of the folding wrench locked on the riser. The upper end of the locking buckle protrudes from the movable notch, which can limit the rotation angle of the locking buckle. When it is necessary to lock the folding wrench on the riser, simply push the folding wrench to push the locking buckle and fasten it in the locking hole, further improving the convenience of locking the riser.
[0012] Preferably, in the folding structure of the scooter described above, the front side of the abutment block is provided with a clearance surface. The upper end of the clearance surface gradually tilts forward along the height direction of the abutment block. When in the unlocked state, the rear end of the abutment block is withdrawn from the locking hole, and the front end of the abutment block is located in the locking hole. When the locking buckle is turned out from the locking hole, the clearance surface and the locking buckle do not interfere with each other.
[0013] When the safety buckle is switched to the unlocked state, the clearance surface can avoid the buckle from being removed from the locking hole. The abutment block does not interfere with the buckle's removal from the locking hole, so the abutment block does not need to be completely removed from the locking hole, which makes it easier for the reset spring to push the abutment block back into the locking hole.
[0014] Preferably, in the folding structure of the scooter described above, the return spring is V-shaped, one side of the return spring abuts against the inner wall of the upright tube opposite to the locking hole, the buckle plate has a mounting groove, the other side of the return spring passes through the mounting groove, and the return spring pushes the abutment block to insert into the locking hole.
[0015] The return spring is V-shaped, which allows it to be fixed in place via the mounting groove and the inner wall of the riser, thus simplifying the assembly of the safety buckle.
[0016] Preferably, the scooter folding structure described above also includes a protective button, which is detachably sleeved on the outside of the buckle.
[0017] The protective button protects the buckle and improves the aesthetics of the safety buckle.
[0018] Preferably, in the folding structure of the scooter described above, the rotating part is provided with an adjusting rod, and the folding wrench is provided with an adjustable positioning screw. The end of the adjustable positioning screw passes through the folding wrench and abuts against the outside of the adjusting rod. The folding wrench drives the adjustable positioning screw to rotate along the adjusting rod.
[0019] The height of the folding wrench on the folding base can be adjusted within a certain range by means of the adjustable positioning screw, thereby improving the applicability of the folding wrench. On the other hand, the folding wrench can be supported by rotating along the adjusting rod through the adjustable positioning screw, which improves the stability of the folding wrench when rotating.

The stem 1, the folding lever 3, and the safety buckle 4 are in a locked state and an unlocked state. In the locked state, the folding lever 3 is folded to the stem 1, the locking buckle 5 is locked in the locking hole 11, and one end of the safety buckle 4 is inserted into the locking hole 11 and prevents the locking buckle 5 from rotating out of the locking hole 11. In the unlocked state, the safety buckle 4 moves into the stem 1, the locking buckle 5 exits from the locking hole 11, and the folding lever 3 unfolds away from the stem 1.
[0030] Preferably, the safety buckle 4 includes a buckle plate 41 with elastic deformation capability and a return spring 42. The buckle plate 41 has a buckle button 411 that extends from the riser 1. One end of the buckle plate 41 has an abutting block 43 that is directly opposite the locking hole 11. The other end of the buckle plate 41 abuts against the inner wall of the riser 1. One end of the return spring 42 abuts against the inner wall of the riser 1. The other end of the return spring 42 is connected to the buckle plate 41 and pushes the abutting block 43 into the locking hole 11. In the locked state, the abutting block 43 abuts against the outside of the locking buckle 5 and interferes with the locking buckle 5 from turning out of the locking hole 11.
[0031] Preferably, the folding wrench 3 has a movable notch 31, the lower end of the locking buckle 5 is rotatably disposed in the movable notch 31, and the upper end of the locking buckle 5 protrudes from the movable notch 31. A pressing spring 311 is disposed in the movable notch 31, one end of the pressing spring 311 is connected to the inner wall of the movable notch 31, and the other end of the pressing spring 311 is connected to the locking buckle 5. The pressing spring 311 pushes the locking buckle 5 to rotate outward from the folding wrench 3.
[0032] Preferably, the front side of the abutment block 43 is provided with a clearance surface 431. The upper end of the clearance surface 431 gradually tilts forward along the height direction of the abutment block 43. When in the unlocked state, the rear end of the abutment block 43 exits from the locking hole 11, and the front end of the abutment block 43 is located in the locking hole 11. When the locking buckle 5 rotates out from the locking hole 11, the clearance surface 431 and the locking buckle 5 do not interfere with each other.
[0033] Preferably, the reset spring 42 is V-shaped, with one side of the reset spring 42 pressing against the inner wall of the riser 1 opposite to the locking hole 11. The buckle plate 41 has a mounting groove 412, and the other side of the reset spring 42 passes through the mounting groove 412. The reset spring 42 pushes the abutment block 43 to be inserted into the locking hole 11.
[0034] Preferably, a protective button 6 is also included, which is detachably sleeved on the outside of the button 411.
[0035] Preferably, the rotating part 22 is provided with an adjusting rod 221, and the folding wrench 3 is provided with an adjustable positioning screw 32. The end of the adjustable positioning screw 32 passes through the folding wrench 3 and abuts against the outside of the adjusting rod 221. The folding wrench 3 drives the adjustable positioning screw 32 to rotate along the adjusting rod 221.
[0036] Specifically, such as Figures 1-3 As shown, the folding seat 2 includes a fixing part 21 for connecting with the pedal and a rotating part 22 rotatably mounted on the upper end of the fixing part 21. The rotating part 22 is arranged with a smaller upper part and a larger lower part. The upright tube 1 is sleeved on the upper end of the rotating part 22 and connected and fixed to the rotating part 22. A locking hole 11 is provided on the front side of the upright tube 1. The upright tube 1 rotates towards or away from the pedal through the rotating part 22.
[0037] like Figures 4-6 As shown, the safety buckle 4 includes a buckle plate 41 with elastic deformation capability. The upper end of the buckle plate 41 abuts against the inner wall of the riser 1. The abutment block 43 is located at the bottom of the buckle plate 41 and extends in the horizontal direction. The mounting groove 412 is distributed in the height direction on the inner wall of the buckle plate 41.
[0038] In this embodiment, the folding seat 2 is made of die-cast aluminum, the buckle plate 41 is made of PP material, the buckle 411 is integrally formed on the buckle plate 41, and the protective button 6 is sleeved and fastened to the outside of the buckle 411. The protective button 6 is made of ABS material, which can play a good anti-scratch role for the safety buckle 4.
[0039] The safety buckle 4 also includes a V-shaped return spring 42. The rear side of the return spring 42 extends downward and abuts against the inner wall of the riser 1 opposite the locking hole 11. The front side of the return spring 42 extends vertically and is inserted into the mounting groove 412. The front side of the return spring 42 is bent into a hook shape and inserted into the abutment block 43. Thus, the return spring 42 can forcefully push the safety buckle 4 to move and reset closer to the locking hole 11.
[0040] More specifically, such as Figures 2-5 As shown, the lower inner wall of the movable notch 31 has an extension post extending outward in the horizontal direction. One end of the pressing spring 311 is sleeved on the extension post. The lower part of the locking buckle 5 has a plug groove. The other end of the pressing spring 311 is inserted into the plug groove and engages with the plug groove. The pressing spring 311 drives the upper part of the locking buckle 5 to rotate out from the locking hole 11. Thus, in the locked state, the lower side of the abutment block 43 is pressed against the locking buckle 5, which improves the locking effect of the riser 1 in the locked state.
[0041] The front side of the abutment block 43 is inclined with a clearance surface 431. The lower end of the clearance surface 431 is inclined towards the rear side of the abutment block 43 along the height direction. Therefore, when the locking buckle 5 is to be turned out of the locking hole 11, the clearance surface 431 can avoid the locking buckle 5 from being turned out of the locking hole 11, without having to completely remove the abutment block 43 from the locking hole 11, thus improving the smoothness of the safety buckle 4 reset.
[0042] When you need to fold riser 1, as follows: Figures 2-5 As shown, first press the protective button 6 inward. At this time, the locking buckle 5 is no longer restricted by the pressing block 43. Then press the lower part of the locking buckle 5 to turn the locking buckle 5 out of the locking hole 11. After turning the folding wrench 3 away from the riser 1, the riser 1 can be folded towards the pedal.
[0043] When it is necessary to fix the riser 1, simply rotate the folding wrench 3 towards the riser 1. The head of the locking buckle 5 contacts the relief surface 431 and pushes the abutment block 43 inward as the folding wrench 3 is rotated further. When the folding wrench 3 is in contact with the outer surface of the riser 1, the head of the locking buckle 5 is locked in the locking hole 11. The abutment block 43 moves and resets under the action of the return spring 42 and is located above the locking buckle 5. Thus, the locking of the riser 1 and the anti-accidental contact function of the locking buckle 5 are realized simultaneously, which is convenient for use.
[0044] In summary, the above are merely preferred embodiments of this utility model. All equivalent variations and modifications made within the scope of the patent application of this utility model shall fall within the scope of this utility model.
