Description

[Technical field]

[0001] The present invention relates to an electric mobility device that allows a rider to select from a variety of travel modes, such as standing and riding, sitting and riding, standing and sitting, pushing and walking, and shopping, depending on the rider's intended use, that can be reduced in overall shape to be compact, and that is equipped with a safety structure that prevents the rider's feet from slipping off the footrest side steps in the event of an impact while riding. [Background technology]

[0002] Conventional electric mobility such as electric kick scooters and electric scooters are formed by mounting a battery or electric motor on a board with wheels and being structured so that it can be charged with a household outlet, and in the higher class, there are products that are legally permitted to be ridden on public roads, and by obtaining a driver's license and license plate and wearing a helmet, they have been commercialized and widely used as a means of transportation for commuting to work or school or shopping. The characteristics of these electric kick scooters are that they are kick scooters with an electric motor attached to a board with wheels, so they have a small environmental impact, are compact and maneuverable, and do not require kicking the ground like conventional kick scooters, so they have the advantage of being able to easily travel to your destination without any effort.

[0003] In light of the above, proposals have been made for mobility such as kickboards and electric kickboards that allow for easy mobility. For example, an "electric kickboard" (Patent Document 1) has been proposed that can reduce the hassle of charging the battery.

[0004] However, while the above-mentioned "electric kickboard" proposals allow the rider to ride while standing, while sitting, or while standing and sitting, depending on the rider's intended use, they are not designed to be used while pushing the scooter while walking, or while shopping with a shopping basket attached.Furthermore, because the side pedals and footboard have a flat structure, there is a risk that the rider's feet will slip off the pedals if the scooter hits an obstacle while riding, and there is no means for folding it up compactly for portability.

[0005] In addition, an electric kickboard has been proposed that is equipped with a shock absorbing device that can suppress excessive shaking and vibration, and supports the user's weight while standing (Patent Document 2).

[0006] However, the above-mentioned proposal for an "electric kickboard equipped with a shock absorbing device that supports the user's weight while standing" allows the rider to ride while standing, while sitting, or while standing and sitting, depending on the rider's intended use, but is designed in such a way that it cannot be pushed while the rider is walking, or used while shopping with a shopping basket attached. Furthermore, because the side pedals, step seat, and side pedals have a flat structure, it does not have a safety feature to prevent the rider's feet from slipping off the side step if the scooter collides with an obstacle while in motion.

[0007] Also proposed is a "self-supporting foldable kick scooter" (Patent Document 3) in which the kick scooter has at least three wheels, a steering column, a footboard, and a spring-loaded folding mechanism that folds the kick scooter autonomously and completely after a short operation of an operating lever, and in which a synchronization rod ensures that the center of gravity of the kick scooter always remains between the at least three wheels and that the kick scooter does not tip over during autonomous folding.

[0008] However, the above-mentioned proposal for a "self-supporting foldable kick scooter" is a self-propelled kick scooter that is propelled by the rider's own kicking power, making it difficult to travel long distances and difficult to use for elderly people who do not have much physical strength or for users with leg disabilities.

[0009] As described above, conventional kick scooters and electric kick scooter proposals were not electric mobility devices like the present invention, which allow the rider to choose from a variety of riding methods depending on the rider's purpose of use, such as standing riding, sitting riding, standing and sitting riding, pushing and walking, and shopping riding, and which also have a safety structure that prevents the rider's feet from slipping off the footrest side steps in the event of an impact while riding.

[0010] The applicant has conceived of the idea of ​​providing an electric mobility vehicle that allows the rider to choose from a variety of driving modes, such as standing riding, sitting riding, standing and sitting riding, pushing and riding while shopping, depending on the rider's intended use, and that can be made compact in overall shape and that is equipped with a safety structure that prevents the rider's feet from slipping off the footrest side steps in the event of an impact while riding. In light of this idea, the applicant has developed an electric mobility vehicle equipped with these functions, and has come to propose the "electric mobility" of this invention.
