Description

Technical Field

[0001] The present invention relates to the field of motorcycles, and in particular to a deformable and foldable electric motorcycle. Background Art

[0002] The existing designated driver vehicles on the market generally use small-wheel diameter foldable frames, which are convenient for storage in the trunk of a car. However, practitioners in the designated driver industry come in all shapes and sizes, and the vehicles they use are basically the same size, resulting in most of them having incorrect riding postures. In order to make a living, they can only compromise and use the bicycles reluctantly, which causes long-term physical discomfort. In evaluating whether a vehicle is good or not, in addition to its performance, appearance, workmanship and price, the most important thing is its human-machine triangle, which is a key parameter for the riding comfort of a vehicle. Currently, most vehicles are generally designed with the human-machine triangle determined by considering that 80% of the population in the target market can meet the standard. Once the human-machine triangle is determined, it cannot be changed. Each vehicle has only one fixed human-machine triangle size. Summary of the Invention

[0016] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0017] A kind of Figure 1-5The deformable folding electric motorcycle shown includes a frame 1, a front wheel 2, a front shock absorber 3, a steering assembly 4, a rear wheel 5, a rear fork 6, and a rear shock absorber 7. The frame 1 includes a crossbeam 11, a front support tube 12, and a rear support tube 13. The front and rear support tubes 12 and 13 are located below the crossbeam and hingedly connected. The front and rear support tubes 12 and 13 are hingedly connected to the crossbeam 11 to form a triangle. The steering assembly 4 is rotatably mounted within a steering shaft tube at the front of the crossbeam 11. The upper end of the front shock absorber 3 is connected to the lower end of the steering assembly 4, and the front wheel 2 is mounted below the front shock absorber 3. A rotating shaft sleeve 14 is mounted on the rear support tube 13 and is capable of rotation. The rotating shaft sleeve 14 is hingedly connected to the rear fork 6 and the rear shock absorber 7 in sequence, forming a triangle. The rear wheel 5 is mounted on the rear fork 6. The power device of this embodiment includes a hub motor arranged on the rear wheel 5, a battery 17 is arranged on the front support tube 12, and a controller 18 is arranged on the rear fork 6. The battery 17, the controller 18, and the hub motor are electrically connected in sequence to provide power for the motorcycle. The controller 18 is also electrically connected to the handlebar tube to facilitate the rider to control the motorcycle.

[0018] A motorized telescopic rod is mounted on the crossbeam 11. The upper end of the front support tube 12 is hinged to the front of the rod housing, and the upper end of the rear support tube 13 is hinged to the rear of the rod. Extending or contracting the rod changes the angle between the front and rear support tubes 12, 13. Footrests 9 are located below the front support tube 12, and a seat cushion 8 is mounted on the telescopic rod. Together, the footrests 9, seat cushion 8, and the steering handlebars on the steering assembly 4 form a variable virtual human-machine triangle. The control button for the motorized telescopic rod is located on the steering assembly 4, allowing the rider to adjust the human-machine triangle to their most comfortable position. Furthermore, when the electric motorcycle is folded, the motorized telescopic rod can be retracted to its minimum size, reducing the motorcycle's size.

[0019] To facilitate folding of the motorcycle without compromising its structural strength during normal riding, this embodiment divides the rear support tube 13 into an upper connecting rod 131 and a lower connecting rod 132. These rods are threaded together, facilitating the installation of the rotating shaft sleeve 14. Two bearings 20 are provided on the upper connecting rod 131, restrained by a shoulder on the lower connecting rod 131 and a shoulder on the upper portion of the upper connecting rod 132. The rotating shaft sleeve 14 is rotatably connected to the upper connecting rod 131 via the bearings 20. A bolt bushing 10 is embedded in the rotating shaft sleeve 14, housing a bolt 15 with a handle. The upper connecting rod 131 has a threaded hole 19 for the bolt 15. In the normal riding state, it is only necessary to screw the handle bolt 15 into the threaded hole 19 to fix the shaft sleeve 14 and the rear support tube 13 relatively. When folding, it is only necessary to withdraw the handle bolt 15 from the threaded hole 19 and rotate it to one side through the shaft sleeve 14, so that the entire rear wheel system is folded toward one side of the frame.

[0020] To further enhance comfort during changes in the ergonomic triangle and ensure that the seat cushion 8 is always at a specific angle to the bottom surface, and that the angle of the seat cushion 8 does not change with telescopic movement, the bottom of the seat cushion 8 in this embodiment has a first connection point 81 and a second connection point 82 from front to back. The second connection point 82 at the rear is hinged to the upper portion of the telescopic rod, while the first connection point 82 is hinged to the upper end of the rear support tube 13 via a chain plate 16. The upper end of the rear support tube 13 has a connecting lug 133 protruding to one side. The angle between the connecting lug 133 and the rear support tube 13 is 55°. As the electric telescopic rod is extended or retracted, changing the angle between the front support tube 12 and the rear support tube 13, the seat cushion 8 is pulled accordingly by the chain plate 16, thereby eliminating changes in the angle between the crossbeam 11 and the bottom surface caused by the raising or lowering of the rear wheel, and ensuring that the seat cushion 8 is always in the designed most comfortable position.
