[0051] The folding and fixing technology of existing two-wheeled vehicles, especially two-wheeled electric scooters, faces significant challenges. The traditional folding mechanism is complex in design and cumbersome to operate. Users need to go through multiple steps to complete folding or unfolding, which not only has a poor user experience, but also is prone to damage due to operation errors. At the same time, these mechanisms have defects in stability and are prone to failure after long-term use. In terms of fixing technology, the traditional pin or bolt fixing method is simple but lacks reliability, and is prone to loosening after long-term use, threatening the safety of driving. In particular, for two-wheeled electric scooters, the folding of the standing pipe causes severe shaking, which not only affects the carrying experience, but also poses a safety hazard.

[0052] Based on the above problems, the present application provides a two-wheeled vehicle folding and fixing mechanism, which is particularly suitable for two-wheeled electric scooters, but can also be used for other types of two-wheeled vehicles. The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0053] A two-wheeled vehicle folding and fixing mechanism, as shown in Figure 1 , Figure 2 It mainly includes a locking assembly, a mounting plate and a forehead assembly.

[0054] The locking assembly includes a sliding lock tongue 1, a locking spring 2 and a lock tongue baffle 3. The sliding lock tongue 1 has a sliding part 11 and a locking part 12, and the upper part of the sliding part 11 is provided with a first groove 111 for unlocking operation. The sliding lock tongue 1 is also provided with a slide rail 13 on both sides, which is used to cooperate with the slide groove in the mounting groove 41 to install the sliding lock tongue 1, so that the sliding lock tongue 1 can slide horizontally along the slide groove.

[0055] One end of the locking spring 2 extends into the mounting hole of the sliding latch 1, and the other end abuts against the limiting plate 413 provided inside the mounting groove 41, providing elastic force for the sliding latch 1 when locking. The latch baffle 3 is used to limit the range of movement of the sliding latch 1 and prevent it from sliding out excessively.

[0056] like Figure 3 , Figure 4 As shown, the mounting plate is a mudguard 4, with an upward protrusion near one side forming a mounting groove 41 for mounting the locking assembly. The mounting groove 41 contains a sliding groove and a limiting plate 413. The sliding groove is symmetrically arranged on both sides of the inner wall of the mounting groove 41 for engaging with the slide rail 13 of the sliding latch 1. A latch baffle 3 is provided at the lower opening of the mounting groove 41, and the latch baffle 3 is connected to the mudguard 4 by screws or welding.

[0057] The overhead assembly 5 is mounted on the vehicle handlebar and is fixedly connected to it. The overhead assembly 5 has a locking hole 51 that mates with the locking assembly. The locking hole 51 can be a through hole or a blind hole, and its shape and size match the locking portion 12 of the sliding latch 1. When the vehicle handlebar is folded, the overhead assembly 5 abuts against the sliding latch 1 of the locking assembly.

[0058] In particular, such as Figure 1 , Figure 6 As shown, the contact surface between the sliding latch 1 and the forehead assembly 5 is an inclined surface, including a first inclined surface 121 and a second inclined surface 122. The slope of the first inclined surface 121 is greater than or equal to the slope of the second inclined surface 122, and the slope range of the first inclined surface 121 is 45° to 60°, while the slope range of the second inclined surface 122 is 30° to 45°. This design allows the latch to extend more smoothly into the locking hole 51 during locking and improves the locking effect.

[0059] like Figure 5 As shown, the contact surface between the forehead assembly 5 and the sliding latch 1 is also set as an inclined surface, namely the third inclined surface 52. In this embodiment, the slope of the third inclined surface 52 is greater than that of the first inclined surface 121 and the second inclined surface 122. This design allows the user to apply only a small force to make the latch slide out of the locking hole 51 along the third inclined surface 52 when unlocking, reducing the difficulty of unlocking.

[0060] In addition, a bumper pad 6 is provided near the latch on the mudguard 4. The bumper pad 6 is made of silicone and is used to provide a limiting and buffering effect when the front assembly 5 is pressed down and folded, so as to protect the locking assembly and the front assembly from damage.

[0061] In application, the two-wheeled vehicle folding and fixing mechanism of the present invention is installed on a two-wheeled vehicle, such as a two-wheeled electric scooter.

[0062] When the vehicle handle needs to be folded, the vehicle handle is pressed down to the folded state, at which time the forehead assembly 5 abuts against the sliding lock tongue 1. Under the elastic force of the locking spring 2, the locking portion 12 of the sliding lock tongue 1 extends into the locking hole 51 of the forehead assembly 5 for locking. When unlocking is needed, the user can reverse the sliding lock tongue 1 by pulling or other means, and the locking portion 12 moves out of the locking hole 51, so that the unlocking operation can be achieved.

[0063] The embodiment provides a two-wheeled electric scooter, which applies the two-wheeled vehicle folding fixing mechanism described in the above embodiment. Through the folding fixing mechanism, the two-wheeled electric scooter can realize stable and convenient folding and unfolding operations, and improve the use experience and carrying convenience of the user.

[0064] In summary, the two-wheeled vehicle folding fixing mechanism and the two-wheeled electric scooter containing the mechanism provided by the embodiment have the advantages of compact structure, convenient operation, stable locking, durability and reliability, and are suitable for the folding fixing needs of various two-wheeled vehicles.

[0065] The working principle of the two-wheeled vehicle folding fixing mechanism is as follows:

[0066] When the handle of the two-wheeled vehicle (such as a two-wheeled electric scooter) needs to be folded, the user first presses down the vehicle handle. With the downward pressing action of the handle, the forehead assembly 5 moves and gradually approaches the locking assembly installed on the fender 4. The pre-set locking hole 51 on the forehead assembly 5 gradually aligns with the locking portion 12 of the sliding lock tongue 1.

[0067] Under the continuous elastic force of the locking spring 2, the sliding lock tongue 1 is pushed towards the forehead assembly 5. Since the abutment surface of the sliding lock tongue 1 is designed as the first inclined surface 121 and the second inclined surface 122, this design enables the locking portion 12 to more smoothly and easily extend into the locking hole 51 of the forehead assembly 5. As the locking portion 12 penetrates deeper, the elastic force of the locking spring 2 further increases, thereby ensuring that the locking portion 12 and the locking hole 51 form a tight lock, achieving stable folding of the vehicle handle.

[0068] When the vehicle handle needs to be unlocked and unfolded, the user only needs to reverse the sliding lock tongue 1 by pulling or other means. Since the abutment surface of the forehead assembly 5 and the sliding lock tongue 1 is designed as the third inclined surface 52 with a larger slope, this design greatly reduces the force required for unlocking. The user only needs to exert a small force to make the locking portion 12 easily slide out of the locking hole 51 along the third inclined surface 52, thereby achieving quick unlocking.

[0069] The anti-collision pad 6 on the fender 4 plays a key role in limiting and buffering during the whole folding and unlocking process.

[0070] In conclusion, the two-wheeled vehicle folding fixing mechanism realizes the convenient folding and stable locking of the vehicle handle, reduces the unlocking difficulty, and improves the use experience and safety through the ingenious design of the locking assembly, the inclined abutting surface and the setting of the anti-collision pad.

[0071] The above only describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc.

[0072] In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of ordinary technical personnel in the art; when the combination of technical solutions appears mutual contradiction or cannot be realized, it should be considered that the combination of technical solutions does not exist, nor is it within the protection scope required by the present application.
