Description

Technical Field

[0001] The present application relates to the field of mobility scooters, and in particular to an electric folding mobility scooter. Background Art

[0002] A mobility scooter refers to a means of transportation and auxiliary tool for the purpose of walking. Compared with internal combustion engines, electric mobility scooters do not produce exhaust gas when in use and do not pollute the environment. They are a clean and environmentally friendly means of transportation. As the society's environmental awareness continues to increase, electric mobility scooters are becoming more and more popular. However, during the research process of this application, the inventor found that the existing mobility scooters are usually large in size and cannot be folded. They take up a large space during transportation and storage, which is very inconvenient to use. Therefore, it is necessary to design an electric folding mobility scooter. Summary of the invention

[0003] The present application provides an electric folding scooter to solve the problems raised in the background technology.

Through the above design, the seat bracket can be unfolded and folded by using the first electric telescopic push rod, thereby greatly reducing the space occupied by the scooter when not in use. In addition, the scooter is usually used by the elderly or other people with mobility difficulties. The scooter of the present application does not require manual operation during folding and unfolding, which greatly improves the convenience of use.

[0005] Preferably, the chassis includes a first chassis and a second chassis, a second electric telescopic push rod is arranged between the first chassis and the second chassis, one end of the second electric telescopic push rod is connected to the first chassis, and the other end is connected to the second chassis. In the present application, the second electric telescopic push rod can be used to realize the automatic extension and retraction of the second chassis and the handle assembly, which can further improve the folding ability of the scooter, and can also automatically adjust the position of the handle assembly according to users of different body shapes, greatly improving the convenience of use.

[0006] Preferably, the number of the connecting rods is 2 and they are symmetrically arranged on both sides of the seat bracket and the first chassis. By providing two connecting rods, the stability of the seat bracket when folding and unfolding can be improved, and better support can also be provided for the seat bracket.

[0007] Preferably, a connecting piece is fixedly connected between the two connecting rods, so that the two connecting rods can keep moving synchronously, thereby improving the stability of the seat bracket when folding and unfolding.

[0008] Preferably, the lower end of the connecting rod includes a first limiting surface and a first rotating surface, the first limiting surface is in a plane shape, and the first rotating surface is in an arc shape, the upper end of the connecting rod includes a second limiting surface and a second rotating surface, the second limiting surface is in a plane shape, and the second rotating surface is in an arc shape, the first limiting surface is located on the front side of the first rotating surface, and the second rotating surface is located on the front side of the second limiting surface. During the process of the seat bracket being lifted up and lowered, the first rotating surface contacts the first base frame, and the second rotating surface contacts the seat bracket to ensure the normal rotation of the connecting rod, and after the seat bracket is lifted up, the first limiting surface contacts the first base frame, and the second limiting surface contacts the seat bracket to limit the connecting rod to prevent excessive rotation.

[0009] Preferably, a backrest bracket is provided at the rear side of the seat bracket, and the bottom of the backrest bracket is hinged to the rear part of the seat bracket. By hingedly connecting the backrest bracket to the seat bracket, the folding ability of the scooter can be further improved.

[0010] Preferably, the handle assembly includes a first connecting section and a second connecting section, wherein the first connecting section is connected to the second base frame, and the second connecting section is arranged on the upper part of the first connecting section and is hinged to the first connecting section. By hingedly connecting the second connecting section to the first connecting section, the second connecting section can be folded toward the rear side of the scooter, thereby further improving the folding ability of the scooter.
