[0002] Electric scooters are small vehicles powered by electricity, mainly used for short-distance travel and urban commuting. Compared with traditional manual scooters, electric scooters are equipped with electric motors, rechargeable batteries and intelligent control systems, allowing users to move quickly without physical exertion. Due to their environmental protection, portability and easy operation, electric scooters have been widely used around the world.

[0003] Although most electric scooters on the market at this stage have a folding function, the folding function is basically based on the telescopic handlebar, which is folded at the connection between the handlebar and the front wheel. The ends of the folded handlebars often protrude beyond the width of the vehicle body and cannot be completely close to or stored in the pedal position. This design causes the scooter to still occupy a large space after folding, especially when the scooter needs to be carried to public transportation, offices or homes and other small spaces, the protruding handlebars become an inconvenient factor. The protruding handlebars are also easy to bump into other objects or the surrounding environment during the carrying process, affecting the user experience.

[0004] Therefore, the current market urgently needs an electric scooter that takes up less space after folding, so that the handlebars can fit closely with the handlebar stem and pedals after folding to form a more compact structure. This design can not only reduce the overall size after folding and improve the portability of the scooter, but also reduce the protruding part of the handlebar after folding, and improve the convenience of storing and carrying the scooter in a small space.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0034] like Figures 1 to 7 The folding locking structure of the electric scooter shown comprises:

[0035] The riser 1 includes a first tube body 11 and a second tube body 12, wherein the first tube body 11 and the second tube body 12 are connected via a first folding locking assembly 2, and one end of the second tube body 12 is connected to the pedal 5 via a second folding locking assembly 3;

[0036] The front end 6 is fixedly connected to one end of the first tube body 11;

[0037] The handlebars 7 include a left handlebar 71 and a right handlebar 72, which have the same structure and are arranged on both sides of the front of the vehicle 6, and are connected to the front of the vehicle 6 through a third folding locking assembly 8;

[0038] The second folding locking assembly 3 is configured such that, when the second folding locking assembly 3 is in a folded state, a storage space 4 for accommodating the first tube 11 is provided between the second tube 12 and the pedal 5, and when the second folding locking assembly 3 is in an unfolded state, the riser 1 and the pedal 5 are locked;

[0039] The first folding locking assembly 2 is configured such that when the first folding locking assembly 2 is in a folded state, the first tube 11 is accommodated in the storage space 4, and when the first folding locking assembly 2 is in an unfolded state, the first tube 11 is locked with the second tube 12;

[0040] The third folding locking assembly 8 is configured such that when the third folding locking assembly 8 is in a folded state, the left handle 71 and the right handle 72 do not exceed the width of the pedal 5 , and when the third folding locking assembly 8 is in an unfolded state, the left handle 71 and the right handle 72 are both locked to the front of the vehicle 6 .

[0041] like Figures 1 to 3 As shown, the utility model designs the vertical tube 1 to be foldable in two, and the handlebar 7 can be accommodated between the pedal 5 and the first tube body 11 by folding the vertical tube 1. In the specific assembly process, the brake line, the light line and the display line can pass through the gap between the furnace tube and each folding locking member, or a part of it passes through the vertical tube 1 and the other part extends to the outside of the vertical tube 1. It should be pointed out here that the first folding locking assembly 2 and the second folding locking assembly 3 have many forms, which can be a rotating hinge type locking assembly, a sliding latch type locking assembly, a spring pin type assembly with a locking button, or other forms that can be folded and locked.

[0042] Through the cooperation of the first, second and third folding locking assemblies 8, the scooter can closely fit the handlebars 7 and the seat tube 1 to the body of the scooter in the folded state, so that the space occupied by the entire scooter is significantly reduced, especially the handlebar 7 part no longer exceeds the width of the pedal 5, thereby forming a more compact folded form. In the unfolded state, each locking assembly can firmly lock each component to ensure that the scooter has sufficient structural stability during use. The folded scooter is more convenient to carry due to its reduced size, especially when it needs to be put into a small space of public transportation, office or home, it can effectively reduce the risk of bumping and improve the carrying convenience of users.

[0043] like Figure 4As shown, the third folding locking assembly 8 includes a first rotating member 81 fixedly connected to the front of the vehicle 6, and a second rotating member 82 fixedly connected to the handlebar 7. The first rotating member 81 and the second rotating member 82 are coaxial and relatively rotatably connected, and a locking assembly 83 is also provided between the first rotating member 81 and the second rotating member 82. Through the coaxial design of the first rotating member 81 and the second rotating member 82, the handlebar 7 can be more flexibly rotated and folded relative to the front of the vehicle 6. The locking assembly 83 ensures the fixation of the handlebar 7 after folding and unfolding. In the unfolded state, the locking assembly 83 can effectively prevent the handlebar 7 from rotating unexpectedly due to external force or vibration, thereby improving the overall stability of the scooter during use and ensuring the safety of the user. It should be pointed out here that the locking assembly 83 has many forms, which can be a mechanical buckle, a bolt rotation, a spring pin or a button, or a combination of several locking forms.

[0044] like Figure 5 As shown, there is also a receiving space 84 between the first rotating member 81 and the second rotating member 82. The receiving space 84 is located at one end of the second rotating member 82 and also has a through hole 84a. The locking assembly 83 is arranged in the receiving space 84 and extends out of the through hole 84a. The receiving space 84 effectively wraps the locking assembly 83, reduces the impact of the external environment (such as dust, moisture, impact, etc.) on the locking assembly 83, and extends the service life of the locking assembly 83. Since the locking assembly 83 is partially hidden in the receiving space 84 and only partially extends through the through hole 84a, it is not easy for the user to accidentally touch or misoperate the locking assembly 83 when operating the scooter. The locking assembly 83 is firmly placed in the receiving space 84, ensuring that the locking assembly 83 is not easy to loosen or shift during use, reducing the risk of accidental unlocking or loosening.

[0045] Continue to refer Figure 5 As shown, the accommodation space 84 includes a first accommodation cavity 84b disposed inside the first rotating member 81, and a second accommodation cavity 84c disposed inside the second rotating member 82. The locking assembly 83 is respectively located in the accommodation cavities of the first and second rotating members 82. This dual-cavity design can increase the support points and contact area of ​​the locking assembly 83, further improving the stability of the locking structure.

[0046] The third folding locking assembly 8 has many forms, and in order to make the operation easier, such as Figure 5As shown, the locking assembly 83 includes a locking pin 83a disposed inside the accommodating space 84, an elastic member 83b sleeved on the locking pin 83a, and a limiting assembly 83c disposed between the locking pin 83a and the first accommodating cavity 84b, wherein one end of the elastic member 83b abuts against the locking pin 83a, and the other end abuts against the first rotating member 81. The locking pin 83a is connected to the first accommodating cavity 84b through the limiting assembly 83c, which can accurately limit the moving range of the locking pin 83a, ensuring that the locking pin 83a can be firmly fixed at a predetermined position in the folded or unfolded state; the elastic member 83b is sleeved on the locking pin 83a, and when the scooter is folded or unfolded to a suitable position, the elastic member 83b can automatically push the locking pin 83a into a locked state to achieve automatic locking; the setting of the limiting assembly 83c fixes the position between the locking pin 83a and the first folding locking assembly 2.

[0047] Continue to refer Figure 5 , Figure 6 As shown, the locking pin 83a includes a push key 83a1 passing through the through hole 84a and protruding from the outer surface of the second rotating member 82, a locking disk 83a2 connected to the push key 83a1 and arranged in the second accommodating cavity 84c, and a pin 83a3 coaxially arranged with the push key 83a1 and the locking disk 83a2, the diameter of the locking disk 83a2 is larger than the diameter of the through hole 84a, and the end of the pin 83a3 extends into the second accommodating cavity 84c. Since the diameter of the locking disk 83a2 is larger than the diameter of the through hole 84a, the locking disk 83a2 cannot pass through the through hole 84a in the locked state, thereby ensuring the stability of the locking assembly 83 during operation; the push button 83a1 protrudes from the outer surface of the second rotating member 82, and the user can unlock or lock the scooter by a simple pressing operation. The locking pin 83a integrates the locking and unlocking functions through the combined design of the push button 83a1, the locking disk 83a2 and the pin 83a3; the push button 83a1 of the locking assembly 83 only protrudes from the surface of the second rotating member 82, and the overall design is compact and simple, with less externally exposed parts, which not only reduces the risk of damage caused by external impact or friction.

[0048] like Figure 5 , Figure 6As shown, the limiting assembly 83c includes a limiting portion 83c1 protruding from the side wall of the pin 83a3, a limiting groove 83c2 provided in the first accommodating cavity 84b, the extending direction of the limiting groove 83c2 is the same as the axial direction of the pin 83a3, and the limiting portion 83c1 extends into the limiting groove 83c2 and can be relatively slidably arranged. The setting of the limiting portion 83c1 and the limiting groove 83c2 enables the locking pin 83a to drive the first rotating member 81 to rotate when the first rotating member 81 and the second rotating member 82 rotate. At the same time, the matching design of the limiting portion 83c1 and the limiting groove 83c2 effectively limits the moving range of the pin 83a3, ensuring that the locking pin 83a can only move within a predetermined axial range, so that the first rotating member 81 can be locked and the locking pin 83a can be pressed and slid.

[0049] As 5 to Figure 7 As shown, the contact surface between the locking disk 83a2 and the second accommodating cavity 84c is also provided with a locking block 85a protruding from the locking disk 83a2, and the second accommodating cavity 84c is provided with a first locking hole 85b and a second locking hole 85c adapted to the locking block 85a, and the first locking hole 85b and the second locking hole 85c are at the same distance from the axial center of the pin 83a3, the first locking hole 85b is configured to lock the handlebar 7 in a folded state, and the second locking hole 85c is configured to lock the handlebar 7 in an unfolded state.

[0050] like Figure 7 As shown, there is also a guide connection groove 85d between the first locking hole 85b and the second locking hole 85c. The cooperation between the locking block 85a on the locking disk 83a2 and the two locking holes allows the user to reliably lock the handlebar 7 in the folded state and the unfolded state. Due to the precise cooperation between the locking block 85a and the locking hole, the user can easily sense whether the locking disk 83a2 is correctly aligned with the locking hole during operation, thereby effectively reducing the situation of locking failure or incomplete locking; the locking block 85a is firmly embedded in the locking hole, which can effectively prevent the handlebar 7 from accidentally loosening or rotating in the folded or unfolded state. Regardless of whether the scooter is in the folded state or the unfolded state, this design can ensure that the handlebar 7 is firmly connected to the front 6. It should be pointed out here that the positions of the first locking hole 85b and the second locking hole 85c are set by the preset folding angle of the handlebar 7.

[0051] Continue to refer Figure 7 As shown, the downward pressing distance of the elastic member 83b is greater than the height of the locking block 85a. The downward pressing distance of the elastic member 83b is greater than the height of the locking block 85a, which ensures that the locking block 85a can be completely separated from the locking hole during the pressing operation. When the locking block 85a is completely separated from the locking hole, it will not rub against the edge of the locking hole during movement, thereby reducing the wear of the locking block 85a and the locking hole.

[0052] Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the description are only for explaining the principle of the present invention.
