Abstract
Description
Technical Field
[0001] This utility model relates to a scooter, specifically a folding scooter. Background Technology
[0002] Folding scooters, currently common in the market, are widely popular due to their lightweight and portability, especially for short-distance commuting and recreational use. However, existing folding scooters generally suffer from the following technical problems during folding and unfolding, affecting their safety and ease of use.
[0003] First, most existing folding scooters use simple hinge or latch structures. These structures typically have only a single locking function; if subjected to significant force or loosened after prolonged use, the folding mechanism may accidentally detach, posing a significant safety hazard. Furthermore, the locking mechanism in the folded state is unreliable, easily unfolding during storage or transport, increasing the risk of damage to the user or other items.
[0004] Secondly, in practice, the design of existing folding structures often fails to adequately consider ease of use. Many folding scooters require users to perform complex manual operations, such as rotating, pressing, and pushing / pulling multiple parts, to complete the folding or unfolding process. This not only increases the difficulty of operation but is also cumbersome and difficult for elderly or children with less strength. Furthermore, the lack of a clear secondary protection structure makes it easy for misoperation to occur during operation, further exacerbating safety hazards.
[0005] Based on the above issues, there is an urgent need for a folding scooter design that is safer in structure and more convenient in operation, in order to solve the problems of insufficient safety and convenience in the existing technology and provide users with a safer and more reliable user experience. Utility Model Content
[0006] To address the aforementioned problems, this utility model provides a folding scooter that is safer and easier to operate, effectively overcoming the shortcomings of existing technologies.
[0007] This utility model is achieved through the following technical solution: a folding scooter, comprising:
[0008] The board body has a rear wheel at one end and a front wheel at the other end. The front wheel is mounted on a front fork. The top of the front fork is a seat tube. The front fork is folded and connected to the board body through a diagonal tube.
[0009] A folding mounting base is fixedly installed on the side of the plate near the front wheel. The front fork is rotatably folded and connected to the folding mounting base. The folding mounting base and the plate are connected by a folding connection mechanism.
[0010] As a preferred technical solution, the folding connection mechanism includes:
[0011] A folding pivot is rotatably mounted in a guide rail movement groove on the folding fixed base;
[0012] A hinge shaft is used to connect the inclined tube to the folding fixing seat;
[0013] The foot pedal has a main body at one end. The middle of the main body is hinged to the inclined tube via a central hinge shaft and a bearing. The end of the main body away from the foot pedal forms a hinge sleeve, which is fitted onto the folding pivot. Stepping on the foot pedal causes the folding pivot to move along the guide rail groove.
[0014] As a preferred technical solution, a tension spring is installed between the folding pivot and the hinge pivot, and the tension spring is elastically stretched when the foot pedal is stepped on.
[0015] As a preferred technical solution, one end of the guide rail movement groove forms a first limiting groove, and the other end of the guide rail movement groove forms a second limiting groove. By stepping on the foot pedal, the folding shaft is separated from the first limiting groove and enters the second limiting groove along the guide rail movement groove.
[0016] As a preferred technical solution, a secondary locking mechanism is also included. The secondary locking mechanism is installed on one side of the inclined tube, and a positioning protection hole is provided on the pedal facing the secondary locking mechanism. The secondary locking mechanism locks into the positioning protection hole to achieve secondary protection.
[0017] As a preferred technical solution, a limiting buckle groove is provided on the inclined tube, and a limiting buckle rod is provided on the folding fixing seat corresponding to the limiting buckle groove, and the limiting buckle rod is fastened into the limiting buckle groove.
[0018] As a preferred technical solution, the folding fixing seat is embedded in the plate body.
[0019] The beneficial effects of this utility model are: by introducing a folding pivot, guide rail movement groove, tension spring and secondary protection mechanism into the structural design of the folding scooter, this utility model not only significantly improves the safety during the folding and unfolding process, but also enhances the overall ease of operation.
[0020] The folding hinge, with the help of a tension spring, can achieve automatic limiting and rebound, avoiding accidental detachment or unfolding due to operational errors. At the same time, through the guide rail movement groove, the folding hinge is accurately positioned in the unfolded and folded states, ensuring the stability of the structure.
[0021] Furthermore, through a secondary protection mechanism, additional locking protection is provided in both the folded and unfolded states, preventing loosening or displacement caused by vibration or external force;
[0022] Meanwhile, by optimizing the linkage structure between the pedal and the folding hinge, users can easily fold or unfold the scooter with a simple step, greatly reducing the difficulty of operation. This makes it especially suitable for users with less strength, thus achieving an organic combination of safety, stability, and convenience, and improving the user experience of the folding scooter.

[0031] 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.
[0032] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.
[0033] like Figures 1-4 As shown, this utility model relates to a folding scooter, including a body 4, a front fork 7, a slant tube 6, a folding fixing seat 3, and a folding connecting mechanism that works with it. It is mainly used to solve the problems of cumbersome operation and insufficient safety of existing folding scooters.
[0034] Specifically, such as Figure 1 As shown, a rear wheel 2 is provided at one end of the board body 4, and a front wheel 1 is installed at the other end. The front wheel 1 is installed at the front end of the board body 4 via a front fork 7. A seat tube 8 is provided on the top of the front fork 7, which provides the user with the function of gripping and controlling.
[0035] The fork 7 is folded and connected to the body 4 via the slant tube 6. One end of the slant tube 6 is fixedly connected to the fork 7, and the other end is connected to the folding fixing seat 3 via the hinge shaft 15.
[0036] The folding fixing seat 3 is fixedly installed on the side of the plate 4 near the front wheel 1, and has a guide rail movement groove 10 inside to limit the movement trajectory of the folding pivot 11. In this embodiment, the embedded setting of the folding fixing seat 3 can ensure a stable connection with the plate 4, thereby enhancing the stability of the overall structure.
[0037] In the folding connection mechanism, the folding pivot 11 is mounted on the folding fixing seat 3 and can rotate and slide along a preset trajectory within the guide rail movement groove 10.
[0038] The initial position of the folding shaft 11 is located at one end of the guide rail movement groove 10, that is, within the first limiting groove 13, through which the folding shaft 11 is positioned.
[0039] The other end of the folding pivot 11 is connected to the inclined tube 6 via the hinge shaft 15. The inclined tube 6 is provided with a limiting groove 16, which corresponds to the limiting rod 17 on the folding fixing seat 3. The limiting rod 17 can be fastened into the limiting groove 16 to provide additional limiting protection for the inclined tube 6 and further improve the structural stability.
[0040] like Figure 5As shown, one end of the foot pedal 4 is the main body 20, which is hinged and supported on the inclined tube 6 via a central hinge shaft 1515 and a bearing 19. The other end of the foot pedal 4 is away from the main body 20 and is mounted on the folding shaft 11 via a hinge sleeve 12. When the user presses down on the foot pedal 4, the folding shaft 11 slides within the guide rail movement groove 10 and gradually moves away from the first limiting groove 13, sliding along the guide rail movement groove 10 to the second limiting groove 9. During this process, the pressing action of the foot pedal 4 and the sliding of the folding shaft 11 are linked, greatly simplifying the folding and unfolding operation process, and the tension spring 14 is continuously stretched.
[0041] A tension spring 14 is positioned between the folding pivot 11 and the hinge shaft 15, providing elasticity during folding or unfolding. When the user presses the foot pedal 4, the tension spring 14 is stretched, driving the folding pivot 11 to slide; after folding, the tension spring 14 rebounds, driving the folding pivot 11 back to the folding limit position, thus achieving automatic limit and rebound functions. This structure effectively prevents accidental detachment or unfolding due to operational errors.
[0042] To further enhance safety, this invention also includes a secondary protection mechanism, installed on one side of the inclined tube 6, corresponding to the positioning protection hole 18 on the pedal. The secondary protection mechanism, via a locking pin inserted into the positioning protection hole 18, provides additional protection in both the folded and unfolded states, preventing the folding structure from loosening or shifting due to vibration or external force. Before folding or unfolding, the user must pull out the locking pin of the secondary protection mechanism to unlock it before continuing operation, providing multiple layers of protection for the folding scooter and ensuring operational safety.
[0043] The work process is as follows:
[0044] When the tension spring 14 is in the rebound state, the folding pivot 11 is located in the first limiting groove 13 in the guide rail movement groove 10. After being hooked, it forms a stable unfolded state. The limiting position of the inclined tube 6 is fixed to the limiting buckle 17 of the folding fixing seat 3 through the hinge shaft 15. The limiting buckle 17 can be fitted with UL glue, and the limiting buckle 17 is fastened into the limiting buckle groove 16 on the inclined tube 6 to form the first limiting protection. At the same time, the locking pin of the secondary protection mechanism is inserted into the positioning protection hole 18 on the foot pedal 4 to achieve the second limiting protection.
[0045] When folding is required, pull out the locking pin of the secondary protection mechanism and rotate it to release it. Step on the foot pedal 4 to stretch the tension spring 14. The folding pivot 11 disengages from the first limiting groove 13 and enters the sliding state of the guide rail movement groove 10. It slides along the guide rail to reach the top folding limiting position. At this time, the tension spring 14 is in a fully extended state. The folding is completed by adjusting the position of the rotating slide rail of the folding pivot 11.
[0046] After folding, the tension spring 14 returns, the folding pivot 11 enters the folding limit groove, the inclined tube 6 and the folding fixing seat 3 are tightly engaged, and while the upright tube 8 is lifted, the secondary protection mechanism is once again engaged with the foot pedal 4 to form the final folded storage state, ensuring that the structure is stable and safe.
[0047] Through the above design, the folding scooter of this utility model achieves efficient linkage between folding and unfolding. At the same time, through multiple limiting and protection measures, it significantly improves the safety and reliability during use, making it especially suitable for children or users with less strength, and providing users with a safer and more convenient user experience.
[0048] 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.
