Abstract

To provide an electric motor-driven roller having a structure capable of being used by being attached to an apparatus to be conveyed as necessary without determining a target in order to spread motor-driven conveyance, and capable of being motor-driven by being attached to a wheelchair, a handcart, and a walking support apparatus.SOLUTION: An in-wheel motor wheel, which is made up of a wheel clutch 6, a motor 1, and a reducer 2 arranged on a body 3, is fixed by a wheel bearing 9, and the vehicle moves by connecting the clutch and driving the motor. A drive board 5, a control board 4, a battery, left and right connecting shafts 7, and left and right connecting clutches 8 are arranged inside the body 3, and straight-line stability is improved by connecting the left and right connecting clutches 8. Manual operation is possible by releasing the wheel clutch 6.SELECTED DRAWING: Figure 1

Description

[Technical field]

[0001] It has an integrated cylindrical or rectangular body with in-wheel motor wheels that rotate independently on the left and right sides, and moves forward and backward by rotating the left and right wheels in the same direction. When turning, the left and right wheels rotate in different directions, and it can be operated manually when the battery runs out. It can be easily attached to hand trucks, shopping carts, wheelchairs, etc. Technical background

[0002] Slow-rotating in-wheel wheels are placed on both ends of the fuselage, and a motor, reducer and clutch are installed inside the wheels. The fuselage is equipped with a drive board, control board, battery, left and right connecting shafts to ensure straight-line stability, and left and right connecting clutches. When the battery runs out, the clutch inside the wheel is released to allow manual operation. As it is integrated, it can be easily attached to transportation equipment to be motorized. Summary of the Invention Problems that the invention aims to solve

[0003] In order to popularize electric transport, we have created a structure that can be attached to the transported equipment as needed, without specifying a target. It can be attached to wheelchairs, handcarts, and walking assistance devices to make them electric. Multiple units can be used to create a dedicated cart, tracks can be attached to make it an off-road model, and GPS can be installed to use it as an unmanned transport vehicle.

[0004] The unit has wheels on both sides and is a cylinder or a square pillar with an integrated body shape, so it can be easily attached to the transported equipment. It is also possible to connect multiple units together and to attach tracks.

[0005] It is low-cost, compact, and easy to install, making it easy to electrify transport equipment, which contributes to society. By installing GPS and anti-personnel radar, it can be used as a self-powered transport device, and by using a load-following motor, it can also be operated as torque assist.
