Description

Technical Field

[0001] This application relates to the field of electric scooter technology, and more specifically, to scooters. Background Technology

[0002] Scooters, as a convenient means of short-distance transportation, have become widely used in urban commuting and leisure activities in recent years. For ease of carrying and storage, most modern scooters feature a foldable design.

[0003] In existing technology, the folding mechanism of a scooter typically consists of a rotating joint between the handlebar stem and the pedals. When the user needs to fold the scooter, they simply rotate the handlebars downwards until they are parallel to the pedals. This design effectively reduces the space occupied by the scooter in a static environment, meeting daily storage needs.

[0004] However, in actual use, especially during transportation and handling, folded scooters are frequently subjected to external forces such as bumps and vibrations. When subjected to continuous vibration or accidental impact, the scooter can easily unfold unexpectedly. This not only increases the difficulty of handling but may also pose safety hazards to transport personnel and surrounding items. Utility Model Content

[0005] The purpose of this application is to provide a scooter that can be locked in a folded state.

[0006] To achieve the above objectives, this application provides a scooter, comprising: A frame and handlebars, wherein the handlebars are foldably mounted on the frame; An elastic buckle is hinged to the vehicle frame and has a slot. A movable tongue is hinged to the handlebars. When the handlebars are folded onto the frame, the movable tongue is inserted into the slot of the elastic buckle, and the handlebars are locked to the frame.

[0007] In an optional embodiment, the elastic buckle includes a hinge portion, a push portion, and a locking portion. The push portion is fixedly connected between the hinge portion and the locking portion. The hinge portion is hingedly mounted on the vehicle frame. The locking portion is provided with the buckle groove. The frame is also equipped with a return spring, which is used to drive the elastic buckle to reset.

[0008] In an optional embodiment, the pressing part is provided with a first anti-slip protrusion.

[0009] In an optional embodiment, the frame is provided with a mounting slot, the hinge is hinged to the inner wall of the mounting slot, and the push part and the locking part extend out of the mounting slot.

[0010] In an optional embodiment, a stop pin is fixedly provided on the inner wall of the mounting slot of the frame, the stop pin being used to limit the rotation angle of the elastic buckle.

[0011] In an optional embodiment, a mudguard is provided on the frame near the mounting slot.

[0012] In an optional embodiment, the movable tongue includes a tongue holder and a locking handle, the tongue holder and the locking handle are respectively hinged to the handlebars, and when the handlebars are folded, the tongue holder is inserted into the slot of the elastic buckle; The handlebar is configured as a telescopic handlebar, and the telescopic handlebar is provided with a top pin for locking the length of the telescopic handlebar. The locking handle pushes the top pin by pushing the tongue bracket, thereby locking the telescopic handlebar.

[0013] In an optional embodiment, the tongue holder includes a snap-fit ​​part and a locking part, the snap-fit ​​part and the locking part are fixedly connected, and the connection between the snap-fit ​​part and the locking part is hinged to the telescopic handle. The snap-fit ​​part is configured as an F-shaped structure. The telescopic handle includes a first sleeve and a second sleeve. The first sleeve is sleeved on the second sleeve. The first sleeve has a locking through hole. The top pin is disposed in the locking through hole of the first sleeve. The locking handle abuts against the locking part to lock the tongue bracket. The locking part pushes the top pin, and the top pin presses against the second sleeve, thereby locking the length of the telescopic handle.

[0014] In an optional embodiment, the locking handle includes a locking block and a handle, the locking block being fixedly connected to the handle, the connection between the locking block and the handle being hinged to the handlebar, and the locking block abutting against the tongue holder.

[0015] In an optional embodiment, the handle is provided with a second anti-slip protrusion.

[0016] Existing scooter folding mechanisms rely solely on a rotating joint between the handlebar stem and the pedals for folding. While this effectively reduces space in a static environment, the scooter is prone to accidental unfolding during transport due to bumps and vibrations. This application addresses this issue by incorporating a flexible latch and a movable tongue structure. When the handlebars are folded into the frame, the movable tongue engages with the latch to lock the scooter in place, effectively resisting external forces, enhancing folding stability, and preventing accidental unfolding. Existing scooters are prone to accidental unfolding, increasing the difficulty of transport. This application ensures a tight connection, making transport easier, more convenient, and more efficient. Furthermore, accidental unfolding of existing scooters poses a safety hazard; this application avoids this situation, ensuring safety and reducing risk.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] like Figure 1 and Figure 2 As shown, embodiments of this application provide a scooter, including a frame 100 and handlebars 200.

[0025] Figure 1 The image shows the scooter frame 100 and handlebars 200, with the handlebars 200 folded onto the frame 100. The image omits conventional structures such as the wheels of the frame 100, as well as the conventional structure that allows the handlebars 200 to hinge to the frame 100.

[0026] like Figure 1 As shown, the handlebars 200 are foldably mounted on the frame 100.

[0027] like Figure 3 As shown, the elastic buckle 300 is hinged on the frame 100, and the elastic buckle 300 can spring back to its original position on the frame 100.

[0028] like Figure 3 and Figure 4 As shown, the elastic buckle 300 has a slot 332.

[0029] like Figure 3As shown, the movable tongue 400 is hinged to the handlebar 200. The handlebar 200 is folded onto the frame 100, so that the movable tongue 400 is inserted into the slot 332 of the elastic buckle 300, and the handlebar 200 is locked to the frame 100.

[0030] In existing technologies, scooter folding mechanisms typically rely solely on the rotary joint between the handlebar 200 stem and the pedals for folding. While this reduces space requirements in a static environment, during transportation and handling, the scooter is prone to accidental unfolding under external forces such as bumps and vibrations, including continuous vibrations or accidental collisions. The scooter of this application, however, incorporates a flexible buckle 300 and a movable tongue 400. When the handlebar 200 is folded onto the frame 100, the movable tongue 400 inserts into the slot 332 of the flexible buckle 300, locking the handlebar 200 to the frame 100. This locking method effectively resists external forces, significantly enhancing the stability of the scooter in the folded state and preventing accidental unfolding.

[0031] Because existing scooters are prone to accidental unfolding under external force, the condition of the scooter needs to be constantly monitored during transport to prevent it from suddenly unfolding and causing obstruction, which undoubtedly increases the difficulty and complexity of transporting them. This application uses a flexible buckle 300 and a movable tongue 400 to ensure a tight connection between the handlebars 200 and the frame 100 in the folded state. Transporters do not need to worry about the scooter accidentally unfolding, making it easier and more convenient to transport the scooter and improving transport efficiency.

[0032] During transportation and handling, the accidental unfolding of scooters not only increases the difficulty of handling but also poses safety hazards to transport personnel and surrounding items. For example, in crowded places or confined spaces, a suddenly unfolded scooter may collide with others or objects, causing injury or damage. This application effectively avoids this situation by ensuring the safety of the transportation and handling process through a reliable locking mechanism, reducing potential safety risks.

[0033] like Figure 4 As shown, in one embodiment, the elastic buckle 300 includes a hinge portion 310, a push portion 320, and a locking portion 330. The push portion 320 is fixedly connected between the hinge portion 310 and the locking portion 330. The hinge portion 310 is hingedly mounted on the frame 100, so that the push portion 320 and the locking portion 330 can rotate around the hinge portion 310, thereby locking or unlocking with the movable latch 400.

[0034] like Figure 4 As shown, the locking part 330 is provided with a slot 332.

[0035] For example, the hinge portion 310, the push portion 320 and the locking portion 330 are fixedly connected by means of welding or integral molding.

[0036] The frame 100 is also equipped with a return spring 500, which is used to drive the elastic buckle 300 to return to its original position.

[0037] For example, the return spring 500 includes, but is not limited to, helical springs, wave springs, disc springs, leaf springs, steel leaf springs, rubber springs, air springs, etc.

[0038] like Figure 4 As shown, when the handlebars 200 are folded towards the frame 100, the movable latch 400 presses against the outer wall of the hinge 310. The hinge 310 rotates under pressure and retracts into the frame 100. During this rotation, the hinge 310 causes the locking groove 332 to change angle, aligning it with the movable latch 400. The movable latch 400 then inserts into the locking groove 332. When the movable latch 400 stops pressing against the hinge 310, the return spring 500 pushes the hinge 310 back to its original position, thus locking the movable latch 400 and the hinge 310 (handlebars 200 and frame 100). The entire process requires no complicated operation; the user simply folds the handlebars 200 normally, and the relevant components automatically lock under mechanical linkage, making it convenient and quick.

[0039] When it is necessary to unlock the handlebars 200 from the frame 100, the user manually presses the push button 320, causing the movable latch 400 to disengage from the slot 332, thus unfolding the handlebars from the frame 100. This design allows users to quickly complete the unlocking operation, improving ease of use.

[0040] The scooter elastic buckle 300 structure provided in this application achieves reliable locking between the handlebars 200 and the frame 100 by setting a hinge part 310, a push part 320 and a locking part 330, and combining them with a return spring 500. This structure not only automatically locks to prevent accidental unfolding due to vibration or collision, but also simplifies the unlocking operation and improves the user's convenience.

[0041] During the folding process of the handlebar 200, the hinge 310 is rotated under pressure and drives the slot 332 to change its angle to align with the movable tongue 400. This design allows the mechanical structure to better adapt to the dynamic changes during the folding process, ensuring reliable locking at various angles and positions, and enhancing the adaptability and stability of the structure.

[0042] like Figure 4 As shown, in one embodiment, the push part 320 is provided with a first anti-slip protrusion 322.

[0043] For example, the first anti-slip protrusion 322 is designed in the shape of a shell and is fixed to the mounting part by bolts or adhesive.

[0044] In another embodiment, the first anti-slip protrusion 322 is integrally formed with the mounting portion.

[0045] The push button 320 is provided with a first anti-slip protrusion 322. When the user manually presses the push button 320 to release the handlebars 200 from the frame 100, the anti-slip protrusion significantly increases the friction between the hand and the push button 320. This allows the user to grip the push button 320 more firmly during operation, even if their hands are sweaty or in a slippery environment, avoiding operational errors caused by slipping hands, thereby improving the accuracy and convenience of operation.

[0046] The first anti-slip protrusion 322 is designed to better conform to the shape and texture of the hand, providing a more comfortable grip. When the user presses the button 320, the anti-slip protrusion can distribute the pressure on the hand, reducing hand fatigue caused by prolonged operation and improving the overall operating experience.

[0047] like Figure 4 As shown, in one embodiment, the frame 100 is provided with a mounting groove 110, the hinge portion 310 is hinged to the inner wall of the mounting groove 110, and the push portion 320 and the locking portion 330 extend out of the mounting groove 110.

[0048] A mounting slot 110 for accommodating the elastic buckle 300 is provided on the frame 100. This design makes full use of the internal space of the frame 100, avoiding the need for additional mounting structures on the outside of the frame 100, making the entire scooter structure more compact. This design, by rationally planning the position of each component inside the frame 100, helps to reduce the overall size of the scooter, making it easier to carry and store.

[0049] Instead of having a large protrusion on the surface of the frame 100, the push-button part 320 and the latch part 330 extend into the mounting slot 110, reducing the space occupied on the surface of the frame 100. In this way, the external dimensions of the scooter will not be excessively increased due to the mechanical structure when the scooter is folded or unfolded, further improving space utilization efficiency.

[0050] The push-button 320 and the latch 330 extend into the mounting slot 110, making it easier for the user to access these components during operation. When it is necessary to lock or unlock the handlebars 200 and the frame 100, the user can directly press the extended push-button 320 without having to search for the operating part in the complex structure of the frame 100, thus improving the convenience and efficiency of operation.

[0051] The mounting slot 110 provides a relatively fixed mounting environment for the hinge 310, making the connection between the hinge 310 and the frame 100 more secure. During the use of the scooter, the mounting slot 110 protects the elastic buckle 300 from various external forces, allowing the hinge 310 to rotate stably within the mounting slot 110, preventing loosening or displacement, thus ensuring the stability of the entire mechanical structure. Concealing the hinge 310 within the mounting slot 110 reduces direct contact between the hinge 310 and external objects, lowering the risk of damage due to collisions or other reasons. Simultaneously, the push part 320 and the locking part 330 extend reasonably beyond the mounting slot 110, preventing excessive protrusion that could lead to snagging with other objects, thus improving the safety of the scooter during use.

[0052] like Figure 4 As shown, in one embodiment, a stop pin 120 is fixedly provided on the inner wall of the mounting groove 110 of the frame 100. The stop pin 120 is used to limit the rotation angle of the elastic buckle 300.

[0053] For example, when the elastic buckle 300 rotates to its limit position under the drive of the return spring 500, the hinge portion 310 abuts against the stop pin 120.

[0054] The stop pin 120 restricts the rotation angle of the elastic buckle 300, ensuring that the return spring 500 pushes the elastic buckle 300 to accurately return to its original position, allowing the movable tongue 400 to precisely align with the slot 332 on the locking part 330. This allows the movable tongue 400 to smoothly insert into the slot 332, achieving a reliable lock between the handlebars 200 and the frame 100. This prevents insecure locking due to deviations in the rotation angle of the elastic buckle 300, and prevents the vehicle body from accidentally unfolding during transportation or handling.

[0055] Without the stop pin 120, the elastic latch 300 might over-rotate under the action of the return spring 500. Excessive rotation could not only cause the elastic latch 300 to collide with the frame 100 and other components, resulting in damage, but could also lead to structural deformation of the elastic latch 300 itself, affecting its normal use. The stop pin 120 effectively prevents this from happening, protecting the elastic latch 300 and related components, and extending the service life of the mechanical structure.

[0056] like Figure 4 As shown, in one embodiment, a mudguard 130 is provided on the frame 100 near the mounting slot 110.

[0057] The mudguard 130 is located on the frame 100 near the rear wheel of the scooter to prevent mud and water splashed out during the rotation of the rear wheel from entering the mounting groove 110.

[0058] For example, the mudguard 130 is fixedly mounted on the frame 100 by means of welding, gluing, bolting or snap-fitting.

[0059] like Figure 4 As shown, in one embodiment, the movable tongue 400 includes a tongue holder 410 and a locking handle 420, which are respectively hinged to the handlebars 200.

[0060] After the handlebars 200 are folded, the tongue bracket 410 is inserted into the slot 332 of the elastic buckle 300.

[0061] The handlebar 200 is configured as a telescopic handlebar, and a top pin for locking the length of the telescopic handlebar is provided on the telescopic handlebar (not shown in the figure, the top pin is provided in the locking through hole 230 described below). The locking handle 420 pushes the top pin by pushing the tongue bracket 410, thereby locking the telescopic handlebar.

[0062] like Figure 4 As shown, in one embodiment, the tongue holder 410 includes a snap-fit ​​portion 412 and a locking portion 414, which are fixedly connected. The fixed connection method is, for example, welding, gluing, or integral molding.

[0063] The connection between the latching part 412 and the locking part 414 is hinged to the handlebar 200. The latching part 412 is configured as an F-shaped structure and latches into the slot 332.

[0064] The telescopic handle includes a first sleeve 210 and a second sleeve 220. The first sleeve 210 is sleeved on the second sleeve 220. The first sleeve 210 is provided with a locking through hole 230. A top pin is provided in the locking through hole 230 of the first sleeve 210. The locking handle 420 abuts against the locking part 414. The locking part 414 pushes the top pin, causing the top pin to move toward the second sleeve 220. The top pin presses against the second sleeve 220, and the first sleeve 210 and the second sleeve 220 are relatively fixed, thereby locking the length of the telescopic handle.

[0065] like Figure 4 As shown, in one embodiment, the locking handle 420 includes a locking block 422 and a handle 424. The locking block 422 and the handle 424 are fixedly connected, and the fixed connection method is, for example, welding, gluing or integral molding.

[0066] The locking block 422 is hinged to the handlebar 200 at the connection point with the handle 424, and the locking block 422 abuts against the tongue holder 410 to lock the tongue holder 410.

[0067] The user rotates the handle 424 to rotate the locking block 422, causing the locking block 422 to abut against the locking part 414 of the tongue bracket 410. The locking part 414 pushes the top pin, causing the top pin to move towards the second sleeve rod 220. The top pin presses against the second sleeve rod 220, and the first sleeve rod 210 and the second sleeve rod 220 are relatively fixed, thereby locking the length of the telescopic handle.

[0068] like Figure 4 As shown, in one embodiment, a second anti-slip protrusion 426 is provided on the handle 424.

[0069] For example, the second anti-slip protrusion 426 is fixed to the handle 424 by means of adhesive, snap-fit, bolt connection or integral molding.

[0070] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0071] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
