[0031] This utility model proposes an electric scooter.

[0032] In the embodiments of this utility model, such as Figures 1 to 5As shown, the electric scooter includes a frame 10, a handlebar assembly 20, and a front wheel 31. The frame 10 includes a footboard 11 and an arched support 12. The arched support 12 is connected to the front end of the footboard 11 and is higher than the upper surface of the footboard 11. A receiving space 1201 is formed below the arched support 12, and a mounting hole 1211 is provided at the top of the arched support 12. The handlebar assembly 20 includes a vertical bar 21, a horizontal handlebar 22 located at the upper end of the vertical bar 21, and a front fork 23 located at the lower end of the vertical bar 21. One of the vertical bar 21 and the front fork 23 is rotatably mounted in the mounting hole 1211, and the front fork 23 is located in the receiving space 1201. The front wheel 31 is mounted on the front fork 23, and part of the front wheel 31 is located in the receiving space 1201.

[0033] Specifically, the electric scooter also includes a rear wheel 32 and a braking device. The rear wheel 32 is installed at the rear end of the pedal 11. The rear wheel 32 and the braking device can refer to the prior art, and will not be described in detail here.

[0034] Both ends of the arched bracket 12 are connected to the front end of the pedal 11. The arch of the arched bracket 12 is centrally located. Compared to the structure of a single link supporting the handlebar assembly 20, the arched bracket 12 has more connection points and a wider connection area with the pedal 11, which can effectively improve the structural strength of the frame 10 and distribute the force, avoid force concentration, and improve durability. It also helps to increase the width of the pedal 11, thereby increasing the area that the user can step on and making it easier for the user to use.

[0035] This utility model's technical solution involves setting an arched bracket 12 at the front end of the pedal 11. A mounting hole 1211 is provided at the arched apex of the arched bracket 12. One of the vertical rod 21 of the handlebar assembly 20 and the front fork 23 is rotatably mounted into the mounting hole 1211, so that the front fork 23 and the front wheel 31 are partially located in the space 1201 below the arched bracket 12. Compared to a structure where a single link supports the handlebar assembly 20, the arched bracket 12 has more connection points and a wider connection area with the pedal 11, effectively improving the structural strength of the frame 10 and distributing stress, avoiding stress concentration, and improving durability. Furthermore, the arched bracket 12 also provides some protection to the side of the front wheel 31, reducing the risk of the front wheel 31 being impacted.

[0036] In some embodiments, the arched bracket 12 and the pedal 11 are formed separately and then connected together by welding or by a locking mechanism. This facilitates the forming of the arched bracket 12 and the pedal 11 and reduces the manufacturing difficulty of the arched bracket 12 and the pedal 11. Of course, in other embodiments, the arched bracket 12 and the pedal 11 can also be formed as a single piece.

[0037] In some embodiments, the arched bracket 12 includes an arched portion 121 and two support portions 122. One end of each support portion 122 has a connecting portion 123 connected to the front end of the pedal 11. The two support portions 122 are spaced apart along the width direction of the pedal 11, and gradually extend upwards in a direction away from the pedal 11. The arched portion 121 connects the ends of the two support portions 122 away from the pedal 11, and a receiving space 1201 is located between the arched portion 121 and the two support portions 122. This arrangement allows the arched portion 121 to be positioned away from the pedal 11, ensuring ample space below the arched portion 121 for mounting the front wheel 31 and the front fork 23. It also reduces interference from the support portions 122 to the front wheel 31, which is beneficial for increasing the steering angle of the front wheel 31.

[0038] Furthermore, the two connection points between the arched bracket 12 and the pedal 11 are distributed at intervals along the width direction of the pedal 11, which can better maintain the balance of the pedal 11 when the width of the pedal 11 is increased, making it convenient for users to use.

[0039] In some embodiments, the support portion 122 is plate-shaped, with its thickness direction aligned with the width direction of the pedal 11. The connecting portion 123 extends along the length direction of the pedal 11. Two fixing plates 111 are provided on the back of the pedal 11, both extending along the length direction and spaced apart along the width direction. Each connecting portion 123 is connected to the inner side of one fixing plate 111. Specifically, the fixing plates 111 are approximately perpendicular to the surface of the pedal 11. This strengthens the structural strength of the pedal 11, reducing the risk of deformation, and also increases the contact area between the connecting portion 123 and the fixing plate 111, improving connection stability. By making the support portion 122 plate-shaped, effective support is provided while reducing the space occupied by the support portion 122 in the accommodating space 1201. This allows for a larger accommodating space 1201 without excessively increasing the width of the arched bracket 12, reducing interference between the support portion 122 and the front wheel 31. Of course, in other embodiments, the support portion 122 can also be tubular, etc.

[0040] Optionally, two fixing plates 111 are respectively disposed on both sides of the pedal 11 along the width direction, so that the distance between the two support parts 122 is as large as possible, which can better distribute the force and maintain the balance of the pedal 11.

[0041] In some embodiments, the back of the footboard 11 is further provided with two reinforcing plates 112, both extending along the length of the footboard 11 and spaced apart between the two fixing plates 111. The electric scooter also includes a battery module 40, which is disposed between the two reinforcing plates 112. Specifically, the reinforcing plates 112 are approximately perpendicular to the surface of the footboard 11 and spaced apart from the fixing plates 111. The distance between the two reinforcing plates 112 is greater than the distance between the reinforcing plates 112 and the fixing plates 111, to ensure sufficient space to accommodate the battery module 40. This arrangement further strengthens the structural strength of the footboard 11, reduces the risk of deformation of the footboard 11, and better protects the battery module 40. Moreover, when the side of the footboard 11 is impacted, even if the fixing plates 111 deform, the distance between the fixing plates 111 and the reinforcing plates 112 reduces the impact on the reinforcing plates 112 and the battery module 40, effectively protecting the battery module 40.

[0042] Optionally, the frame 10 also includes a cover plate 13 connected to two reinforcing plates 112 to cover the battery module 40 between the two reinforcing plates 112, thereby protecting the battery module 40.

[0043] In some embodiments, the arched bracket 12 further includes a reinforcing member 124 located at the front end of the pedal 11 and connected to two reinforcing plates 112. The reinforcing member 124 is connected between two support portions 122. Specifically, the reinforcing member 124 includes a first plate 1241 and two second plates 1242 perpendicularly connected to the first plate 1241. The first plate 1241 and the second plates 1242 are integrally formed. Each second plate 1242 is connected to the outer side of a reinforcing plate 112 (the side facing away from the battery module 40). The first plate 1241 is connected between the two support portions 122, and the thickness direction of the first plate 1241 is approximately parallel to the length direction of the pedal 11. This configuration can improve the structural strength of the support portion 122 through the reinforcing member 124, reducing the risk of deformation of the support portion 122. It can also protect the battery module 40 through the reinforcing member 124, reducing the risk of damage to the front end of the battery module 40 from impacts by foreign objects during driving.

[0044] In some embodiments, the arched portion 121 includes an integrally formed arched body 1212 and an upper plate 1213. The upper plate 1213 is located above the arched body 1212, with both ends of the upper plate 1213 connected to the arched body 1212. The portion between the two ends of the upper plate 1213 is spaced from the arched body 1212, and the mounting hole 1211 penetrates through the upper plate 1213 and the arched body 1212. That is, the portion of the arched portion 121 with the mounting hole 1211 is multi-layered, which can effectively improve the structural strength at the mounting hole 1211 and also avoid excessive weight of the arched bracket 12. Optionally, the frame 10 also includes a sleeve 14, which is installed in the mounting hole 1211 and welded to the arched portion 121. One of the vertical rod 21 and the front fork 23 is rotatably installed in the sleeve 14.

[0045] In some embodiments, the electric scooter also includes a locking screw that secures the connecting part 123 to the footboard 11. This ensures a reliable connection between the connecting part 123 and the footboard 11 while facilitating assembly.

[0046] In some embodiments, the electric scooter also includes a housing 50 that covers the arched support 12 and is connected to the footboard 11. This allows the arched support 12 to be concealed, reducing requirements for the arched support 12 beyond structural strength (such as appearance, cleanliness, etc.), while the housing 50 can be made of materials such as plastic or stainless steel to meet requirements beyond load-bearing capacity.

[0047] In some embodiments, a wiring space is formed between the arched bracket 12 and the housing 50. A first cable routing hole 1202 is provided on the arched bracket 12 near the pedal 11, communicating with the wiring space. A second cable routing hole 51 is provided on the housing 50 away from the pedal 11, communicating with the wiring space. That is, the cable harness leading from the pedal 11 extends into the wiring space through the first cable routing hole 1202 and exits through the second cable routing hole 51 to reach the handlebar assembly 20. This utilizes the space between the arched bracket 12 and the housing 50 for cable routing, reducing cable exposure and providing better protection for the cable harness.

[0048] In some embodiments, the housing 50 is provided with a through hole 52 communicating with the receiving space 1201; that is, when a person stands behind the handlebar assembly 20, the situation in the receiving space 1201 can be seen through the through hole 52, facilitating the inspection of the status of the front wheel 31 and the front fork 23. Optionally, the housing 50 also has a baffle 53, which gradually slopes upward in a direction away from the pedal 11, and the through hole 52 is formed on the top of the baffle 53. In this way, the baffle 53 can block water or sand splashed onto the pedal 11 during riding.

[0049] In some embodiments, the electric scooter further includes a mounting housing 61 and two mudguards 62. The mounting housing 61 is mounted on the outside of the front fork 23, and the two mudguards 62 are respectively located on the front and rear sides of the mounting housing 61, both covering the front wheel 31. Thus, the mudguards 62 are fixed by the cooperation between the mounting housing 61 and the front fork 23. Optionally, the mudguards 62 are integrally formed with the mounting housing 61, reducing assembly steps and facilitating assembly.

[0050] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
