Description

Technical Field

[0001] The utility model relates to the field of electric scooters, in particular to an electric scooter with a new drive device. Background Art

[0002] The new drive technologies of electric scooters mainly include hub motors and belt drive systems. These technologies play a key role in improving the performance, efficiency, and user experience of electric scooters. A hub motor is a motor installed at the center of the scooter wheel, directly driving the wheel to rotate. This configuration can convert electrical energy into mechanical energy more efficiently, reducing energy loss. Since the motor is directly integrated into the hub, the overall design of the scooter is more compact and the weight is relatively reduced, making it more convenient to carry and operate. The application of the hub motor not only simplifies the power transmission system but also improves the response speed and acceleration performance of the scooter. The belt drive system uses a durable rubber or polyurethane belt to transmit the power generated by the motor to the wheel. Compared with traditional chain drives, the belt drive is smoother and quieter during operation, providing a more comfortable riding experience for users. The use of the belt reduces the maintenance frequency and cost because it is not easily affected by dust and moisture and has stronger durability.

[0003] For example, in the utility model patent with the Chinese patent number CN 208306902 U, a drive structure of an electric scooter is disclosed, which includes a handlebar, a box body, a partition board, and a wheel. An expansion rod is arranged below the handlebar, a support board is arranged below the inclined rod, and a first fixing block is arranged below the support board. A box cover is arranged above the box body, and a storage battery is arranged above the inner part of the box body. A vertical board is arranged on the left side of the storage battery, and a spring is arranged on the left side of the vertical board. A fixing board is arranged below the partition board, and a fan is arranged on the left side of the fixing board. A second fixing block is arranged on the right side of the wheel, and a fixing rod is arranged inside the second fixing block. A hole is arranged on the right side of the fixing rod, a cross bar is arranged inside the hole, and a motor is arranged on the right side of the cross bar. This drive structure of the electric scooter can be freely disassembled and assembled, can provide shock absorption, fix the storage battery, and can cool the overall device.

[0004] Although the above patent realizes the new dual-wheel drive of the electric scooter and effectively solves the defects of the existing electric scooters on the market, such as single-motor driving single-wheel structure, insufficient driving torque during driving, slow start and difficult climbing, poor driving and braking stability, the need for external support for parking, and long braking distance, during the actual use of the electric scooter, due to the misalignment of the box body and the support board, when encountering uneven roads, the box body will rub against the road surface, affecting the actual use effect and practicality. Therefore, technological innovation is carried out on this basis. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. The typical embodiments of the present utility model are shown in the drawings. Embodiment

[0022] As Figures 1-4As shown in the figure, the electric scooter with a new drive device of the present utility model includes a frame 1. A drive assembly 2 is fixed on the surface of the frame 1, and a limiting assembly 3 is arranged on the surface of the drive assembly 2. The drive assembly 2 includes a sleeve one 201 fixed inside the frame 1, and the drive assembly 2 further includes a connecting frame 202 arranged on the rear-end surface of the frame 1. A hub motor 203 is fixed inside the connecting frame 202, and a side plate 204 is fixed on the inner wall of the connecting frame 202. A connecting column 205 is fixed on the surface of the side plate 204. The drive assembly 2 further includes a connecting cylinder 206 fixed on the rear-end surface of the frame 1, and an annular cylinder 207 is fixed on the inner surface of the connecting cylinder 206. A limiting groove 208 is opened on the surface of the annular cylinder 207, and a spring one 209 is arranged inside the annular cylinder 207. A convex column one 210 is movably connected inside the annular cylinder 207, and a limiting column 211 is fixed inside the convex column one 210. A limiting hole 216 is opened on the side surface of the connecting frame 202.

[0023] As Figures 1-4 shown, the inner wall of the annular cylinder 207 contacts with the surface of the connecting column 205. The convex column one 210 sequentially penetrates through the annular cylinder 207 and the connecting column 205 and extends into the inside of the connecting column 205.

[0024] As Figures 1-4 shown, a chute one 212 is opened on the surface of the sleeve one 201, and a spring two 213 is arranged inside the sleeve one 201. A convex column two 214 is movably connected inside the sleeve one 201, and a sliding column one 215 is fixed on the surface of the convex column two 214.

[0025] As Figures 1-4 shown, the surface of the sliding column one 215 contacts with the surface of the chute one 212, and the surface of the convex column two 214 contacts with the surface of the limiting hole 216.

[0026] During implementation, through the setting of the connecting frame 202 and the hub motor 203, the frame 1 and the connecting frame 202 are located at the same water level position, avoiding that when the connecting frame 202 is too low and encounters an uneven road surface, it will rub against the road surface. When it is necessary to disassemble the connecting frame 202 and the hub motor 203, by sliding the limiting column 211, the limiting column 211 drives the convex column one 210 to slide, so that the convex column one 210 is separated from the connecting column 205. At the same time, slide the sliding column one 215, and the sliding column one 215 drives the convex column two 214 to slide, so that the convex column two 214 is separated from the limiting hole 216. Slide the connecting frame 202, and the connecting frame 202 can be separated from the frame 1, which is convenient for disassembling the connecting frame 202 and the hub motor 203. Embodiment

[0027] As Figures 1-4As shown, on the basis of the first embodiment, the present utility model provides a technical solution: The limiting component 3 includes a limiting cylinder 301 fixed to the surface of the vehicle frame 1, and the limiting component 3 further includes an arc-shaped block 302 fixed to the top surface of the vehicle frame 1. A second sliding groove 303 is formed on the surface of the limiting cylinder 301, and a third spring 304 is provided inside the limiting cylinder 301. A third convex column 305 is movably connected inside the limiting cylinder 301, and a second sliding column 306 is fixed to the surface of the third convex column 305.

[0028] As Figures 1-4 shown, a connecting plate 307 is installed on the inner surface of the arc-shaped block 302 through a rotating shaft, and a limiting block 308 is provided on the surface of the connecting plate 307.

[0029] As Figures 1-4 shown, the third convex column 305 sequentially penetrates through the limiting cylinder 301 and the limiting block 308 and extends into the limiting block 308, and the bottom surface of the connecting plate 307 is in contact with the top surface of the vehicle frame 1.

[0030] During implementation, when it is necessary to repair the inside of the vehicle frame 1, by sliding the second sliding column 306, the second sliding column 306 drives the third convex column 305 to slide, so that the third convex column 305 is separated from the limiting block 308, and then the connecting plate 307 can be rotated to separate the connecting plate 307 from the vehicle frame 1, facilitating the repair of the inside of the vehicle frame 1.

[0031] The advantages of this technical solution in practical applications include but are not limited to the following points:

[0032] 1. A connecting frame 202 and a hub motor 203 are provided inside the driving component 2. The vehicle frame 1 and the connecting frame 202 are located at the same water level position, avoiding the problem that when the connecting frame 202 is too low and encounters an uneven road surface, it will rub against the road surface, improving the actual use effect and practicability. By providing a connecting cylinder 206 and a first sleeve 201 inside the driving component 2, by sliding the first convex column 210 and the second convex column 214, the connecting frame 202 can be separated from the vehicle frame 1, making it more convenient to disassemble the connecting frame 202 and the hub motor 203;

By providing the limiting cylinder 301 and the third convex column 305 inside the limiting component 3, by sliding the third convex column 305, the third convex column 305 can be separated from the limiting block 308, facilitating the rotation of the connecting plate 307, and thus the inside of the vehicle frame 1 can be repaired.

[0034] In this technical solution, through the settings of the connecting frame 202 and the in-wheel motor 203, the frame 1 and the connecting frame 202 are located at the same water level position, avoiding the situation that the connecting frame 202 is too low and will rub against the road surface when encountering uneven road surfaces. When it is necessary to disassemble the connecting frame 202 and the in-wheel motor 203, by sliding the limit post 211, the limit post 211 drives the first convex post 210 to slide, so that the first convex post 210 is separated from the connecting column 205. At the same time, slide the first sliding post 215, and the first sliding post 215 drives the second convex post 214 to slide, so that the second convex post 214 is separated from the limit hole 216. Slide the connecting frame 202, and the connecting frame 202 can be separated from the frame 1, which is convenient for disassembling the connecting frame 202 and the in-wheel motor 203. When it is necessary to repair the inside of the frame 1, by sliding the second sliding post 306, the second sliding post 306 drives the third convex post 305 to slide, so that the third convex post 305 is separated from the limit block 308, and then rotate the connecting plate 307 to separate the connecting plate 307 from the frame 1, which is convenient for repairing the inside of the frame 1.
