The drive wheel then drives the driven wheel to rotate, thus propelling the scooter forward. In certain special applications, such as offshore operations or hill climbing, the equipment sways violently due to high waves, and tilts significantly when climbing. Traditional transmission structures are prone to slippage in these situations and cannot brake in time, resulting in long braking distances.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-3 :

[0023] A gear-driven electric scooter includes a scooter assembly that travels on an I-beam 1. The scooter assembly includes a main plate 2 and a secondary plate 3 distributed on both sides of the I-beam 1. The main plate 2 and the secondary plate 3 are respectively provided with scooter wheels 4 that are rolled and connected to the upper surface of the lower edge of the I-beam 1. A rack 5 distributed along the direction of travel is provided at the center of the bottom of the I-beam 1. An output gear shaft 7 driven by a reduction motor 6 is rotatably arranged between the main plate 2 and the secondary plate 3. The output gear shaft 7 is located directly below the rack 5, and the gear 8 on the output gear shaft 7 meshes with the rack 5 for transmission.

[0024] In this embodiment, the geared motor 6 is a general-purpose model, including a motor and a gearbox. The output shaft of the gearbox is an output gear shaft 7 fitted with gear 8. During operation, the operator presses the operation button to start the geared motor 6, and the output gear shaft 7 rotates accordingly. Since the rack 5 is fixed to the bottom of the I-beam 1, when the output gear shaft 7 rotates, through the transmission of the meshing gear 8 and rack 5, the output gear shaft 7 moves forward or backward along the rack 5, thereby driving the trolley wheel 4 to roll along the I-beam 1, driving the entire trolley to work. Since the gear 8 and rack 5 are always in a meshed state, the electric trolley in this embodiment has strong anti-shaking and anti-tilt capabilities. At the same time, the high torque drive of the geared motor 6 can well adapt to the needs of offshore or uphill operations. In addition, the transmission structure in this embodiment is centrally located at the bottom of the I-beam 1, and the output gear shaft 7 passes through the main plate 2 and the secondary plate 3, which also brings better balance.

[0025] This embodiment further integrates the overall layout with other structures of the electric sports car. Specifically, the reduction motor 6 is located on the outer side of the main board 2, and the outer side of the sub-board 3 has an electrical box 9 and a counterweight plate 10. The power distribution system of the electric sports car is centrally located in the electrical box 9. Furthermore, the main board 2 and the sub-board 3 are symmetrically distributed. The reduction motor 6 is located at the lower part of the main board 2, and the counterweight plate 10 and the electrical box 9 are located at the upper part of the sub-board 3, i.e., the reduction motor 6, the counterweight plate 10, and the electrical box 9 are staggered. Through the above layout and the placement of the counterweight plate 10, the balance of the electric sports car can be further enhanced.

[0026] The assembly structure of the output gear shaft 7 in this embodiment is as follows: the geared motor 6 is connected to the main board 2 through the flange bearing 11, the sub-plate 3 is provided with a bushing 12, the bushing 12 is provided with a bearing, and the two ends of the output gear shaft 7 are respectively assembled in the bearings of the flange bearing 11 and the bushing 12.

[0027] To increase the connection strength, the counterweight plate 10 is fixedly connected to the sub-plate 3 via a bracket 13, and the electrical box 9 is fixed on the outside of the counterweight plate 10; preferably, the bracket 13 is a pair of U-shaped brackets 13.

[0028] In the aforementioned 8-gear transmission electric sports car

[0029] A carriage shaft 14 and a reinforcing connecting rod 15 are provided between the main board 2 and the sub-board 3. The axes of the output gear shaft 7, the carriage shaft 14, and the reinforcing connecting rod 15 are arranged in parallel, and the reinforcing connecting rod 15 and the output gear shaft 7 are respectively located on both sides of the carriage shaft 14. The carriage shaft 14 can firmly connect the electric hoist; the reinforcing connecting rod 15 can increase the structural strength of the carriage.

[0030] To further improve the stability of the sports car, the sports car wheels 4 on the main board 2 and the sub-board 3 are symmetrically distributed and each has more than two wheels. The front and rear sides of the main board 2 and the sub-board 3 are rotatably equipped with limiting rollers 16 that are rolled and connected to the lower side of the I-beam 1.

[0031] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
