Description

Technical Field

[0001] The utility model relates to a scooter, in particular to a foldable scooter. Background Art

[0002] Scooters are a common means of transportation in our daily lives. To facilitate portability and storage, their size must be minimized, leading to the development of retractable and foldable scooters. For example, the folding mechanism of existing scooters is often incorporated into the larger steering column or pedal section, significantly reducing the overall size.

[0003] For example, conventional steering rods are constructed by pivoting two rods radially on one side and interlocking them on the other side to achieve foldability. However, this structure creates a large space between the two rods when folded relative to each other, which can easily cause pinching injuries to the operator. Furthermore, since the rods are only connected at two radial points, their structural strength is poor and they lack anti-loosening or locking mechanisms, making them prone to loosening and raising safety concerns.

[0004] Therefore, it is necessary to provide a novel and progressive folding scooter to solve the above-mentioned problems. Utility Model Content

[0028] The following examples are merely used to illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention, so it is clearly stated in advance.

[0029] Please refer to Figures 1 to 14 , which shows a preferred embodiment of the present invention. The folding scooter 1 of the present invention includes a vehicle body 10, a steering rod 20 and an operating mechanism 30.

[0030] The vehicle body 10 includes a pedal portion 11 and at least one first wheel 12 mounted on the pedal portion 11. The pedal portion 11 comprises a first portion 111 and a second portion 112 pivotally connected. A recessed groove 113 is defined at one end of the first portion 111, and a convex section 114 is defined at one end of the second portion 112. The convex section 114 is received in the recessed groove 113. A steering rod 20 is rotatably mounted on the vehicle body 10 and connected to at least one second wheel 40 at one end. The steering rod 20 comprises a first rod portion 21 and a second rod portion 22 that can be folded relative to each other. A stopper 23 is provided at the upper end of the steering rod 20. When the pedal portion 11 is folded, the convex section 114 extends transversely to the recessed groove 113. When the steering rod 20 is folded toward the pedal portion 11, the stopper 23 is positioned within the recessed groove 113. This structure simplifies the structure, and the folded structure is stable and resistant to shaking.

[0031] In this embodiment, a swinging member 24 is connected to the upper end of the steering rod 20, and the stopper 23 is connected (e.g., sleeved) to the swinging member 24. The stopper 23 also facilitates grasping and pulling the swinging member 24. The swinging member 24 can be a trigger of a tightening mechanism for tightening the handle. The stopper 23 expands in a direction away from the swinging member 24, providing a good blocking effect. The stopper 23 is preferably a flexible element, such as a rubber, plastic or silicone element, which can stably press against the recessed groove 113. Preferably, the width of the stopper 23 can be greater than, equal to, or slightly smaller than the width of the recessed groove 113. This can effectively maintain the folded structure and prevent shaking, thereby preventing damage to the folded part, and avoiding collisions between components and noise generated by collisions.

[0032] Specifically, the first rod portion 21 includes two pivoting walls 211 disposed opposite to each other, at least one of the two pivoting walls 211 (preferably both) having at least one latching slot 212. The second rod portion 22 includes a pivoting end 221 rotatably connected to the two pivoting walls 211. The operating mechanism 30 includes a movable member 31 and at least one latching key 32. The movable member 31 is disposed on the second rod portion 22 and can slide axially along the second rod portion 22 to a locked position ( Figure 8 ) and a release position ( Figure 9 ), the at least one latching key 32 is disposed on the movable member 31. When the movable member 31 is in the locked position, the at least one latching key 32 engages with the at least one latching slot 212, preventing the pivoting end portion 221 and the two pivoting walls 211 from rotating relative to each other. When the movable member 31 is in the released position, the at least one latching key 32 is not engaged with the at least one latching slot 212, allowing the pivoting end portion 221 and the two pivoting walls 211 to rotate relative to each other. This results in a simple structure, convenient and quick folding operation, and reliable locking, providing excellent reliability and safety.

[0033] In this embodiment, the first rod portion 21 is the lower portion of the steering rod 20. In other embodiments, the first rod portion 21 may be the upper portion of the steering rod 20. The first wheel 12 is connected to the second rod portion 22. The first rod portion 21 further includes a first rod member 213 and two attachment members 214. The two attachment members 214 are relatively fixed (or removably connected) to the first rod member 213. Each attachment member 214 includes a pivot wall 211. Each attachment member 214 further includes a half-tube portion 215 connected to the pivot wall 211 and fixed to the first rod member 213. The two attachment members 214 are independent components, facilitating assembly, disassembly, replacement, and maintenance. Preferably, the first rod portion 21 further includes two arc-shaped shell members 216, which are respectively stacked with the half-tube portions 215 of the two attachment members 214 and fixed (which can be detachably connected) to the first rod member 213 by at least one fastening member 50. The top ends of the two arc-shaped shell members 216 respectively abut against the two pivot walls 211, thereby supporting the two attachment members 214 and strengthening the overall structural strength.

[0034] The second rod portion 22 is provided with a guide groove 223, and the at least one latch key 32 is inserted into the guide groove 223 and can slide along the guide groove 223. The second rod portion 22 also includes a second rod member 222, which is inserted into the pivot end portion 221. A pivot member 60 passes through and connects the two pivot walls 211, the pivot end portion 221 and the second rod member 222. The movable member 31 is tubular and is sleeved on the second rod member 222. The movable member 31 is provided with a through hole 311. In detail, the second rod member 222 is provided with the guide groove 223, and the at least one latch key 32 is inserted into the through hole 311 and the guide groove 223. A rib 312 is further provided on the outer side of the movable member 31. The through hole 311 is opened on the rib 312. The rib 312 can enhance the structural strength of the movable member 31. Preferably, the foldable scooter 1 further includes an elastic member 70, which can be disposed between the operating mechanism 30 and the pivot member 60, or between the operating mechanism 30 and the second rod 222 (e.g., the pin 80), thereby enabling the movable member 31 to automatically return to the locked position after operation.

[0035] The pivot end portion 221 includes an outer peripheral surface 224, a slot 225, and at least one (preferably multiple) slots 226. The outer peripheral surface 224 extends in an arcuate manner around the pivot member 60. The slot 225 is recessed radially inward from the outer peripheral surface 224. The at least one slot 226 axially extends through the end surface of the pivot end portion 221 and is radially open at one end. The second rod 222 is inserted into the slot 225, facilitating assembly, disassembly, replacement, and maintenance, while also providing greater structural strength. When the movable member 31 is in the locked position, the at least one latch 32 is located in the at least one slot 226, stably and robustly restraining the at least one latch 32.

[0036] Preferably, the first rod portion 21 further includes an end structure 217 that extends in an arc relative to the pivot member 60. This end structure 217 faces and mates with the outer circumferential surface 224 of the pivot end portion 221, effectively reducing gaps between components, facilitating smooth rotation, and providing good support. The end structure 217 can be formed on the two arc-shaped shells 216 or the two attachment members 214, or can be formed on both the two attachment members 214 and the two arc-shaped shells 216.

[0037] The operating mechanism 30 further includes a pull rod 33, a trigger 34 and a shaft 35. The pull rod 33 is axially movable and passes through the movable part 31 and the second rod portion 22. The at least one latch key 32 is provided on the pull rod 33 (which can be integrally formed or a multi-piece combination). One end of the pull rod 33 is provided with (can be screwed) an enlarged head 331, which is blocked outside the pivot wall 211. The shaft 35 is provided through the trigger 34 and is connected (for example, screwed) to the other end of the pull rod 33. The trigger 34 can swing around the shaft 35 to releasably tighten the two pivot walls 211, so that the two pivot walls 211 abut against opposite sides of the pivot end 221, thereby improving the reliability of the locking. Preferably, the portion of the pull rod 33 including the at least one latch 32 is non-circular (eg, rectangular), and the through hole 311 of the movable member 31 is also non-circular, to prevent the pull rod 33 from rotating and ensure locking stability.

[0038] The above is a preferred embodiment of the present invention and the technical principles used therein. For those skilled in the art, any obvious changes such as equivalent transformations, simple replacements, etc. based on the technical solution of the present invention, without departing from the spirit and scope of the present invention, shall fall within the scope of protection of the present invention.
