[0053] The present invention will be described below in conjunction with specific implementation manners.

[0054] As Figures 1 to 3As shown in the figure, an improved electric skateboard structure includes a skateboard main body 7, which includes a board surface base 71 and a board surface upper cover 72 screwed to the upper end of the board surface base 71. A main body accommodation cavity 73 is formed inside the skateboard main body 7 between the board surface base 71 and the board surface upper cover 72, and a power battery 8 is embedded in the main body accommodation cavity 73.

[0055] Furthermore, as Figures 1 to 3 shown in the figure, walking drive components are respectively installed at the front end and the rear end of the skateboard main body 7. Each walking drive component respectively includes a board surface support 1, a movable hinge seat 2, a left wheel assembly 31, a right wheel assembly 32, a left shock-absorbing link assembly 41, and a right shock-absorbing link assembly 42.

[0056] Even further, as Figures 4 to 7 shown in the figure, the movable hinge seat 2 is located below the corresponding board surface support 1, and the movable hinge seat 2 is hinged to the board surface support 1 through a central return shaft 5; a left elastic rubber block 61 and a right elastic rubber block 62 are installed between the movable hinge seat 2 and the board surface support 1. The left elastic rubber block 61 is located on the left end side of the central return shaft 5, and the right elastic rubber block 62 is located on the right end side of the central return shaft 5. The lower ends of the left elastic rubber block 61 and the right elastic rubber block 62 respectively abut against the movable hinge seat 2, and the upper ends of the left elastic rubber block 61 and the right elastic rubber block 62 respectively abut against the board surface support 1. It should be explained that the left elastic rubber block 61 and the right elastic rubber block 62 are respectively PU rubber blocks; of course, the above materials do not constitute a limitation to the present invention, that is, the left elastic rubber block 61 and the right elastic rubber block 62 of the present invention can also be prepared from other plastic materials.

[0057] Among them, as Figures 4 to 7 shown in the figure, the left wheel assembly 31 includes a left wheel shaft mounting seat 311, the left wheel shaft mounting seat 311 is screwed with a left transverse wheel shaft 312 and a left drive motor 314 located beside the left transverse wheel shaft 312 and electrically connected to the power battery 8. The left transverse wheel shaft 312 is equipped with a left walking wheel 313, the left drive motor 314 is drivingly connected to the hub of the left walking wheel 313, and the left shock-absorbing link assembly 41 is installed between the left wheel shaft mounting seat 311 and the movable hinge seat 2. Similarly, the right wheel assembly 32 includes a right wheel shaft mounting seat 321, the right wheel shaft mounting seat 321 is screwed with a right transverse wheel shaft 322 and a right drive motor 324 located beside the right transverse wheel shaft 322 and electrically connected to the power battery 8. The right transverse wheel shaft 322 is equipped with a right walking wheel 323, the right drive motor 324 is drivingly connected to the hub of the right walking wheel 323, and the right shock-absorbing link assembly 42 is installed between the right wheel shaft mounting seat 321 and the movable hinge seat 2.

[0058] It should be noted that the left driving motor 314 of the present invention can be drivingly connected to the hub of the left traveling wheel 313 in the following manner. Specifically: as Figures 4 to 7 shown, a left driving pulley 315 is installed on the power output shaft of the left driving motor 314, a left driven pulley 316 is screwed on the hub of the left traveling wheel 313, and a left transmission belt is wound between the left driving pulley 315 and the left driven pulley 316. Similarly, the right driving motor 324 of the present invention can be drivingly connected to the hub of the right traveling wheel 323 in the following manner. Specifically: as Figures 4 to 7 shown, a right driving pulley 325 is installed on the power output shaft of the right driving motor 324, a right driven pulley 326 is screwed on the hub of the right traveling wheel 323, and a right transmission belt is wound between the right driving pulley 325 and the right driven pulley 326. Of course, the above driving connection manner between the driving motor and the hub of the corresponding traveling wheel does not constitute a limitation to the present invention. For example: the driving motor can be drivingly connected to the hub of the corresponding traveling wheel through a gear transmission structure or a chain transmission mechanism.

[0059] It should be further pointed out that, as Figures 4 to 6 shown, the left shock-absorbing link assembly 41 includes a left support link 411 and a left auxiliary link 412 arranged in parallel and at intervals with the left support link 411. The left end portions of the left support link 411 and the left auxiliary link 412 are respectively hinged to the left wheel axle mounting seat 311 through pivot shafts, and the right end portions of the left support link 411 and the left auxiliary link 412 are respectively hinged to the movable hinge seat 2 through pivot shafts; a left shock absorber 413 is installed between the left support link 411 and the movable hinge seat 2. One end of the left shock absorber 413 is hinged to the left support link 411 through a pivot shaft, and the other end of the left shock absorber 413 is hinged to the movable hinge seat 2 through a pivot shaft. During operation, since the left support link 411 and the left auxiliary link 412 are arranged in parallel and at intervals, and the distance between the hinge positions at both ends of the left support link 411 is equal to the distance between the hinge positions at both ends of the left auxiliary link 412, this structural design can effectively ensure that the left traveling wheel 313 remains in a vertical state without yaw when the left shock-absorbing link assembly 41 moves; the left support link 411 is shock-absorbingly supported by the left shock absorber 413, and the left shock absorber 413 is used to achieve the shock-absorbing effect.

[0060] Similarly, as Figures 4 to 6As shown in the figure, the right shock-absorbing link assembly 42 includes a right support link 421 and a right auxiliary link 422 arranged in parallel and spaced apart from the right support link 421. The right end portions of the right support link 421 and the right auxiliary link 422 are respectively hinged to the right wheel axle mounting seat 321 through pivot shafts, and the left end portions of the right support link 421 and the right auxiliary link 422 are respectively hinged to the movable hinge seat 2 through pivot shafts. A right shock absorber 423 is installed between the right support link 421 and the movable hinge seat 2. One end of the right shock absorber 423 is hinged to the right support link 421 through a pivot shaft, and the other end of the right shock absorber 423 is hinged to the movable hinge seat 2 through a pivot shaft. During operation, since the right support link 421 and the right auxiliary link 422 are arranged in parallel and spaced apart, and the distance between the hinge positions at both ends of the right support link 421 is equal to the distance between the hinge positions at both ends of the right auxiliary link 422, this structural design can effectively ensure that the right walking wheel 323 remains in a vertical state without yaw when the right shock-absorbing link assembly 42 moves. The right support link 421 is shock-absorbingly supported by the right shock absorber 423, and the right shock absorber 423 is used to achieve the shock-absorbing effect.

[0061] For each walking drive assembly, the left elastic rubber block 61 and the right elastic rubber block 62 installed between the movable hinge seat 2 and the board surface bracket 1 are respectively elastic structures, that is, the elastic structure composed of the left elastic rubber block 61 and the right elastic rubber block 62 can form a shock-absorbing structure between the movable hinge seat 2 and the board surface bracket 1. When the electric skateboard makes a turning motion, when the left elastic rubber block 61 is compressed by force, the left walking wheel 313 and the right walking wheel 323 will be misaligned and yawed to achieve left turning movement; when the left elastic rubber block 61 is compressed by force, the left walking wheel 313 and the right walking wheel 323 will be misaligned and yawed to achieve right turning movement.

[0062] In addition, when the present invention makes a walking movement, the power battery 8 supplies power to the left drive motor 314 and the right drive motor 324 of each walking drive assembly. The left drive motor 314 of each walking drive assembly drives the corresponding left walking wheel 313 to move, and the right drive motor 324 of each walking drive assembly drives the corresponding right walking wheel set to move to achieve the walking movement action.

[0063] Based on the above situation, through the above structural design, the present invention has the advantages of novel structural design and good shock-absorbing effect.

[0064] As a preferred embodiment, as Figures 4 to 7As shown in the figure, the board surface support 1 includes a board surface connection part 11 connected to the board surface main body, and an arched installation part 12 in an "n" shape is arranged at the front end of the board surface connection part 11. Preferably, the board surface connection part 11 of the board surface support 1 is screwed to the board surface base 71 through a locking screw.

[0065] Among them, the arched installation part 12 includes an installation part top plate 121, an installation part front side plate 122 arranged at the front end of the installation part top plate 121, and an installation part rear side plate 123 arranged at the rear end of the installation part top plate 121. The movable hinge seat 2 is located between the installation part front side plate 122 and the installation part rear side plate 123, and the movable hinge seat 2 is located below the installation part top plate 121. The front end of the central return shaft 5 is connected to the installation part front side plate 122, and the rear end of the central return shaft 5 is connected to the installation part rear side plate 123. The left elastic rubber block 61 and the right elastic rubber block 62 are respectively located between the installation part top plate 121 and the movable hinge seat 2.

[0066] Preferably, the installation part top plate 121, the installation part front side plate 122, and the installation part rear side plate 123 are of an integral structure, and the arched installation part 12 and the board surface connection part 11 are of an integral structure; of course, the above integral structure design does not constitute a limitation to the present invention.

[0067] As a preferred implementation manner, as Figure 4 , Figure 6 and Figure 7 shown, a V-shaped plate 13 in a "V" shape is screwed and fixed to the lower surface of the installation part top plate 121, and the upper ends of the left elastic rubber block 61 and the right elastic rubber block 62 are respectively abutted against the V-shaped plate 13.

[0068] Through the structural design of the V-shaped plate 13, when the skateboard or scooter makes a turning movement, the V-shaped plate 13 can well transfer the force to the left elastic rubber block 61 or the right elastic rubber block 62.

[0069] As a preferred implementation manner, as Figure 6 shown, to ensure that the left elastic rubber block 61 and the right elastic rubber block 62 can be stably and reliably installed between the movable hinge seat 2 and the board surface support 1, the present invention adopts the following structural design. Specifically: downward-opening limiting holes 63 are respectively formed at the lower ends of the left elastic rubber block 61 and the right elastic rubber block 62, and limiting screws are respectively screwed to the movable hinge seat 2 corresponding to the respective limiting holes 63, and the upper ends of the respective limiting screws are respectively inserted into the corresponding limiting holes 63.

[0070] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present invention.
