Abstract
Description
Technical Field
[0001] This utility model relates to the field of mobility scooter technology, specifically a retractable omnidirectional mobility scooter. Background Technology
[0002] The existing mobility scooters on the market consist of a frame chassis, front end, seat, and battery. Due to the differences in user size, larger users can only use larger mobility scooters, while smaller ones are completely unusable. In addition, they have high requirements for road surface conditions when steering, and cannot turn or make U-turns in narrow sections, resulting in a poor driving experience.
[0003] Furthermore, since personal mobility vehicles are typically used in narrow, bumpy environments such as residential areas and park sidewalks, drivers face significant limitations in operation and use. Some roads are simply impassable, and larger users are often constrained by the vehicle's size. Therefore, it is essential to design a solution to these problems. Utility Model Content
[0004] The purpose of this invention is to provide a retractable omnidirectional mobility scooter that solves the problems mentioned in the background art.
[0005] Technical solution
[0006] To achieve the above objectives, this utility model provides the following technical solution: a retractable omnidirectional mobility scooter, comprising an omnidirectional wheel assembly and a motor rear wheel. A telescopic device is located above the omnidirectional wheel assembly, and a telescopic locking device is provided on the telescopic device. A folding device for the front of the telescopic device is located on its upper surface, and a handlebar assembly is located above the folding device. A folding device is also provided on the upper surface of the telescopic device, and a seat is located on top of the folding device. A backrest is fixedly installed on the right side of the seat, and armrests are provided on the side of the seat. A battery is located on the surface of the telescopic device and below the seat. The motor rear wheel has two wheels, and an anti-tilt wheel is located between the two motor rear wheels.
[0007] Furthermore, the universal wheel device is connected to the folding device shaft at the front of the vehicle, and the universal wheel device can rotate 360° in both the horizontal and vertical directions.
[0008] Furthermore, the folding device at the front of the vehicle is connected to the handlebar mechanism pivot, and it can be folded down by a maximum of 90° by pressing down the folding handle.
[0009] Furthermore, the handlebar assembly is equipped with an instrument panel and an automatic return shaft.
[0010] Furthermore, the telescopic device is screwed to the front folding device.
[0011] This utility model provides a retractable omnidirectional mobility scooter. It has the following beneficial effects:
[0012] This retractable omnidirectional mobility scooter features a folding mechanism at the front that allows for both folding and retracting handlebars, adjustable to a comfortable angle and height for the user. The retractable mechanism adjusts the length by pressing the retractable locking device, altering the wheelbase. The locking device also features an automatic spring-loaded locking mechanism. The folding mechanism allows the scooter to be folded down when not in use and unfolded when needed. The armrests can be pulled outwards to adjust the seat width. The backrest can be folded down to reduce bulk and folded up when needed, with a self-locking mechanism. A battery provides power to the entire scooter and can be used individually or in pairs. The rear motor moves the scooter forward and backward or adjusts its speed based on signals from the handlebar mechanism, and allows for differential steering. The handlebar mechanism also features an automatic return-to-center pivot, allowing the scooter to rotate automatically during use without needing to control the front wheel, achieving full-angle steering via the rear wheel. Anti-roll wheels provide support and protection against tipping. Attached Figure Description
