Description
Technical Field
[0001] This utility model relates to a folding structure for an electric scooter. Background Technology
[0002] With the rapid development of urban transportation, electric scooters, as a convenient personal transportation tool, are gradually gaining popularity among consumers due to their flexibility and environmental friendliness. However, despite significant progress in the performance and design of existing electric scooters, there are still some technical issues that need to be addressed in the folding structure design, affecting their user experience and practicality.
[0003] Current electric scooter folding mechanisms mostly employ simple mechanical connections, with folding components typically linked by hinges, latches, or pins. While these designs meet basic folding requirements, they still have some significant drawbacks:
[0004] In existing folding structures, the connection of folding parts often relies on simple buckles or pins for fixation. These connection methods are prone to loosening or misoperation during use, which can lead to the folding parts opening accidentally or becoming unstable, affecting the safety of the scooter. In particular, when riding at high speed or encountering vibrations, the folding parts may loosen or even fall off.
[0005] Existing folding mechanisms often require cumbersome operating procedures, such as manually adjusting multiple components, pins, or latches, increasing the complexity and difficulty of use, especially in inconvenient external environments, making operation inconvenient for users. Furthermore, existing structures lack precise positioning during folding or unfolding, making them prone to misoperation, resulting in incomplete folding or unfolding and impacting the user experience.
[0006] Some connecting parts of folding mechanisms are prone to wear, loosening, or breakage, especially under high-frequency use. Because the folding parts need to withstand significant repeated pulling and impact forces, the durability and reliability of traditional designs are questionable, affecting the lifespan of the electric scooter. Utility Model Content
[0007] The purpose of this utility model is to provide a folding structure for electric scooters, which solves the problems that may occur in the use of electric scooter folding structures, such as instability, complicated operation, large size, and poor durability, thereby improving the convenience, safety, stability and durability of folding operation and enhancing the user experience.
[0008] The technical solution adopted by this utility model to solve its technical problem is:
[0009] A folding structure for an electric scooter includes a skateboard section and a rear wheel section disposed behind the skateboard section and forming a concave-convex fit with the skateboard section; the folding structure further includes a folding portion disposed between the rear wheel section and the skateboard section, the folding portion comprising:
[0010] A rotating part is disposed between the skateboard part and the rear wheel part. The rotating part includes a rotating hole that passes through the skateboard part and the rear wheel part, and a rotating shaft that is inserted into and fixed in the rotating hole.
[0011] A limiting part, disposed between the skateboard part and the rear wheel part, includes:
[0012] The first limiting groove is provided inside the skateboard section;
[0013] The second limiting groove is provided in the rear wheel section;
[0014] A sliding block accommodated within the first limiting groove and the second limiting groove;
[0015] The control handle is located on one side of the sliding block;
[0016] The spring is located inside the sliding block and abuts against the sliding block.
[0017] Preferably, the rotating shaft is fixedly connected to the slide plate and the rear wheel via bearings.
[0018] Preferably, the control handle is used to control the movement of the sliding block within the first and second limiting grooves, and the control handle protrudes beyond the slide plate and rear wheel, and has a moving hole for the control handle to move.
[0019] Preferably, the movable hole is located on one side of the rear wheel section, and the movable hole is arranged laterally.
[0020] Preferably, the first limiting groove and the second limiting groove are aligned, the height and width of the first limiting groove and the second limiting groove are the same, and the depth of the first limiting groove is less than the depth of the second limiting groove.
[0021] Preferably, the length of the sliding block is greater than the depth of the first limiting groove.
[0022] Preferably, the sliding plate part is provided with a ramp corresponding to the rotating part position, and the rear wheel part is provided with a chamfer corresponding to the rotating part position to cooperate with the ramp.
[0023] The beneficial effects of this utility model are:
[0024] This solution, by incorporating a rotating and limiting component and precisely controlling a sliding block, ensures the folding section remains stably locked during folding and unfolding, preventing unsafe situations. Furthermore, a control handle is designed to move the sliding block between the first and second limiting slots, making the folding and unfolding process more convenient, faster, and more precise. Users can easily complete folding or unfolding simply by operating the control handle, without relying on complex mechanical devices or overly cumbersome steps.
[0025] The rotating part of the folding structure, through the combination of a rotating hole and a rotating shaft, ensures that the folding part will not experience excessive wear or become choppy even after long-term use, thereby improving the overall durability and reliability of the structure. This folding structure design allows the electric scooter to fold more compactly, reducing its space requirements and making it easier for users to store and carry, especially when used on public transportation. By simplifying the operation process and optimizing the structural design, the folding operation of the electric scooter becomes more intuitive and easier, enhancing the user experience, particularly in scenarios involving frequent folding and unfolding.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example
[0033] See Figure 1-4 As shown, a folding structure for an electric scooter includes a skateboard section 1 and a rear wheel section 2 disposed behind the skateboard section 1 and forming a concave-convex fit with the skateboard section 1; the folding structure further includes a folding section 3 disposed between the rear wheel section 2 and the skateboard section 1, the folding section 3 comprising:
[0034] Rotating part 31 is disposed between the sliding plate part 1 and the rear wheel part 2. The rotating part 31 includes a rotating hole 311 passing through the sliding plate part 1 and the rear wheel part 2, and a rotating shaft 312 fixedly inserted into the rotating hole 311.
[0035] A limiting part 32 is disposed between the skateboard part 1 and the rear wheel part 2, and the limiting part 32 includes:
[0036] The first limiting groove 321 is provided in the skateboard part 1;
[0037] The second limiting groove 322 is provided in the rear wheel section 2;
[0038] A sliding block 323 is accommodated in the first limiting groove 321 and the second limiting groove 322;
[0039] The control handle 324 is located on one side of the sliding block 323;
[0040] The spring 325 is located inside the sliding block 323 and abuts against the sliding block.
[0041] By providing a control handle 324 on one side of the sliding block 323, users can more easily operate the folding structure. The control handle 324 makes the movement of the sliding block 323 more intuitive and convenient, allowing users to easily complete the folding and unfolding process, reducing cumbersome operating steps and improving ease of use. The spring 325 can hold the sliding block 323 in place. The rotating part 31, through the cooperation of the rotating hole 311 and the rotating shaft 312, ensures a more secure and stable connection between the skateboard part 1 and the rear wheel part 2. The design of the rotating part 31 avoids loosening and instability between the skateboard part 1 and the rear wheel part 2, preventing safety hazards caused by loose or unstable connecting parts during use.
[0042] The first limiting groove 321 and the second limiting groove 322, in conjunction with the sliding block 323, effectively restrict the relative movement between the skateboard part 1 and the rear wheel part 2, preventing unnecessary loosening or displacement of the folding structure during use and improving the overall structural stability. The sliding block 323 prevents structural misoperation, ensuring the folding part 3 remains in the correct position. The placement of the sliding block 323 within the first and second limiting grooves 321 and 322 ensures that the rear wheel part 2 and the skateboard part 1 are precisely guided into position during folding. This precise limiting design avoids dangers caused by incorrect folding, such as accidental opening or incomplete locking of the folding part 3. Adjusting the movement of the sliding block 323 via the control handle 324 reduces the risk of user misoperation, ensuring the accuracy and safety of folding and unfolding operations.
[0043] The design of the rotating shaft 312 and the limiting groove makes the connection of the three folding parts more stable, able to withstand greater repeated use loads, reduce wear and loosening problems, and improve the durability of the three folding parts. Compared with traditional connection methods such as pins and buckles, the structure of the rotating shaft 312 and the sliding block 323 is more robust and durable.
[0044] The rotating shaft 312 is fixedly connected to the slide plate part 1 and the rear wheel part 2 via bearings. The control handle 324 is used to control the movement of the sliding block 323 within the first limiting groove 321 and the second limiting groove 322. The control handle 324 protrudes outside the slide plate part 1 and the rear wheel part 2 and has a moving hole 325 for the control handle 324 to move. The moving hole 325 is located on one side of the rear wheel part 2 and is arranged laterally.
[0045] The rotating shaft 312 is fixedly connected to the slide plate part 1 and the rear wheel part 2 via bearings. This design effectively reduces friction and minimizes wear on the rotating part 31 during long-term use. The bearings provide smooth rotational support, ensuring the rotating part 31 maintains good stability and durability, thereby extending the service life of the folding part 3 and preventing loosening or failure due to friction and wear. The control handle 324 controls the movement of the sliding block 323 within the limiting groove, allowing precise adjustment of the sliding block 323's position to ensure the connection between the slide plate part 1 and the rear wheel part 2 is always in the correct position. This makes folding and unfolding operations more convenient and accurate. Users can easily adjust the structure using the control handle 324, avoiding instability or misoperation caused by improper operation in traditional folding structures.
[0046] The control handle 324 protrudes from the skateboard portion 1 and the rear wheel portion 2, and can be easily adjusted via the sliding hole 325. The lateral arrangement of the sliding hole 325 makes operation more intuitive and easier for the user to control. The lateral design makes the torque more balanced during operation, avoiding the instability or inconvenience that may result from a vertical design. In addition, the protruding design of the control handle 324 makes it easier for the user to grip and use, thereby improving the overall user experience.
[0047] The first limiting groove 321 is aligned with the second limiting groove 322. The height and width of the first limiting groove 321 and the second limiting groove 322 are the same. The depth of the first limiting groove 321 is less than the depth of the second limiting groove 322. The length of the sliding block 323 is greater than the depth of the first limiting groove 321.
[0048] The first limiting groove 321 and the second limiting groove 322 are aligned, and their inner height and width are consistent. This ensures the precise engagement of the sliding block 323 within the limiting groove. The aligned design prevents the sliding block 323 from shifting within the groove, ensuring that the sliding block 323 remains in the correct position during use, thereby improving the stability and positioning accuracy of the overall structure.
[0049] The depth of the first limiting groove 321 is less than the depth of the second limiting groove 322, and the length of the sliding block 323 is greater than the depth of the first limiting groove 321. This design allows the sliding block 323 to fully enter the first limiting groove 321 and provides a deeper insertion space in the second limiting groove 322, thus providing stronger fixing force. This differentiated depth design helps to achieve smooth sliding and precise locking during use, preventing the sliding block 323 from becoming unstable due to insufficient insertion or improper operation.
[0050] The length of the sliding block 323 is greater than the depth of the first limiting groove 321, ensuring sufficient contact area within the groove and providing stronger locking force. This design effectively prevents the block from loosening or sliding irregularly during use, increasing the safety and durability of the mechanical structure. Furthermore, the depth difference design prevents the block from being completely jammed in actual use, maintaining a certain degree of freedom and reducing the risk of damage or jamming.
[0051] The skateboard part 1 is provided with a ramp corresponding to the rotating part 31, and the rear wheel part 2 is provided with a chamfer corresponding to the rotating part 31 to cooperate with the ramp.
[0052] The design of the ramp and chamfer effectively guides the movement trajectory of the sliding components during rotation, making the sliding process smoother. The chamfer reduces sharp-angle collisions between parts, lowers friction, and prevents jamming or uneven movement, thereby improving overall rotational stability and reducing rotational resistance. The chamfer design creates a smooth transition area at the contact point between the ramp and the rear wheel 2, avoiding right angles or sharp contact surfaces and reducing wear caused by friction between parts during movement. This design significantly reduces wear caused by friction, extending the service life of the mechanical structure, especially under long-term, high-frequency use.
[0053] The design of ramps and chamfers helps to accommodate the tolerances of components during assembly, avoiding jamming or structural instability caused by improper assembly. During assembly, chamfers effectively guide the alignment of parts, ensuring correct positioning and fit of each component, thereby improving overall assembly accuracy and reducing debugging time.
[0054] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of this utility model, shall fall within the scope of protection of this utility model.
