DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings. Embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the specification of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0023] This embodiment provides an independent four-wheel drive structure for an electric bus. During the use of this independent four-wheel drive structure, it is more conducive to the disassembly, assembly and maintenance between the motor gear and the motor. Specifically, as Figures 1-4 shown, it includes a drive motor 1 for driving the independent wheels of the bus, a gear assembly 2, a spring 3 and a limiting member 4. A first groove 11 is formed on the surface of the output shaft of the drive motor 1. A connecting plate 12 is provided on the surface of the output shaft of the drive motor 1. The connecting plate 12 is designed in an "L" shape. A first clamping groove 121 is formed on the surface of the connecting plate 12. The gear assembly 2 includes a sleeve 21 and a gear disc 22. A first opening 23 is formed through the surface of the sleeve 21. The position of the first opening 23 corresponds to that of the first groove 11. The gear disc 22 is arranged outside the sleeve 21. A second opening 24 is formed through the surface of the gear disc 22. One side of the connecting plate 12 away from the output shaft protrudes to one side of the gear disc 22 through the second opening 24. The spring 3 is arranged in the first groove 11. The limiting member 4 includes a clamping block 41 and a rotating plate 42. The clamping block 41 is designed in a cylindrical shape. The clamping block 41 protrudes between the first opening 23 and the first groove 11. The spring 3 is located between the clamping block 41 and the output shaft and is in a compressed state. A convex rod 43 is provided on the surface of the clamping block 41. The rotating plate 42 is sleeved outside the convex rod 43. A baffle 431 is arranged annularly on the outer side of one end of the convex rod 43. The rotating plate 42 is located between the baffle 431 and one end of the convex rod 43 to prevent the separation and dropping between the rotating plate 42 and the convex rod 43. A convex plate 421 protruding into the first clamping groove 121 is provided on the surface of the rotating plate 42. When the gear assembly 2 needs to be disassembled from the output shaft of the drive motor 1, only the limiting member 4 needs to be adjusted and taken out by hand. The disassembly and assembly operations do not require auxiliary tools, which is more conducive to the disassembly and assembly operations between the gear assembly 2 and the output shaft.

[0024] As Figure 4 shown, in this embodiment, a second groove 411 is formed annularly at one end of the clamping block 41. A plurality of rotors 5 are arranged inside the second groove 411. The rotors 5 are solid metal balls with a smooth surface. The bottom surface of the rotating plate 42 is in contact with the surfaces of the plurality of rotors 5. The surface of the rotating plate 42 is set as a smooth surface, which is more conducive for the staff to press and rotate the rotating plate 42, and the rotation process is more relaxed and convenient.

[0025] As Figures 1-2 shown, in this embodiment, a part of the surface of the convex plate 421 protrudes outside the connecting plate 12. Anti-slip lines are engraved on the surface of the convex plate 421. The convex plate 421 is designed with an alloy material. When the staff rotates the rotating plate 42, they can hold the convex plate 421 to apply pressure and rotate it, which is more conducive for the staff to apply pressure and rotate the rotating plate 42.

[0026] As Figure 1As shown in the figure, in this embodiment, two second grooves 13 are formed on the surface of the output shaft of the driving motor 1, and two protrusions 211 protruding into the second grooves 13 are arranged on the inner side of the sleeve 21, so as to realize the limiting effect between the sleeve 21 and the output shaft of the driving motor 1, which is more conducive to the corresponding position between the first groove 11 and the first opening 23 during the installation process.

[0027] During the use of the four-wheel independent drive device, if it is necessary to disassemble and assemble between the gear assembly 2 and the output shaft of the driving motor 1, the staff can press and rotate the convex plate 421 downward, so that the convex plate 421 is separated from the connecting plate 12. At this time, the spring 3 in the compressed state in the output shaft of the driving motor 1 rebounds, and the clamping block 41 is taken out between the first groove 11 and the first opening 23 through the convex plate 421. Finally, the gear assembly 2 can be taken out towards the end far away from the driving motor 1.

[0028] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
