Self-propelled floor-sweeping machine

Abstract

The present invention provides a self-propelled floor-sweeping machine, capable of turning around a small corner and lively running even that a driver ride. The self-propelled floor-sweeping machine is operated by one driver to clean the road surface, and includes a main body (S) and a running drive part (D); the main body includes a rotary brush and an driven wheel; the running drive part includes a frame equipped with a drive source and a steering mechanism; a driving seat arranged on the upper surface of the frame; and a drive wheel (2) rotatingly mounted on the lower surface of the frame; the drive wheel is arranged below the driving seat (8); and the drive wheel is a hub motor with a built-in motor. The weight of the driver is applied to the drive wheel arranged below the driving seat, such that the load of the driven wheel is reduced. The drive wheel is a hub motor and is capable of outputting a high torque even that the machine is of a low speed, so as to obtain friction with the ground for driving to run at a certain speed to reliably cleaning the ground or the road surface.

Description

Technical field [0001] The invention relates to a self-propelled cleaning machine. In more detail, it relates to a self-propelled sweeper that is driven by a driver and sweeps the road or the ground. Background technique [0002] As a conventional self-propelled cleaning machine, there is an invention described in Patent Document 1. [0003] This prior art is a self-propelled cleaner that seeks to make the vehicle body compact without impeding the sweeping function of garbage, water, etc., and is configured as follows. [0004] There are at least three wheel bodies that support the vehicle body to travel, a brush that is arranged on the vehicle body and rotates to sweep out garbage, and a garbage collection box that accommodates the garbage swept out by the brush. 2 of the three wheel bodies The two wheels are drive wheels, and the drive wheels are composed of the rotor of an outer rotor type electric motor supported on the vehicle body side. The remaining 1 wheel is a small drive...

AI Technical Summary

Problems solved by technology

However, the direction of the car body is changed by the difference in the rotation speed of the left and right driving wheels, which increases the radius of rotation, and the direction change by the small driven wheels has a small friction with the ground, so there is a disadvantage that reliable direction change cannot be performed.

Therefore, there is a problem that the small turns required by the self-propelled sweeper cannot be achieved

[0006] In addition, the vehicle body equipped with three wheels cannot be bent. Therefore, in places where the road surface is inclined in a convex or concave shape, the wheels cannot smoothly contact the ground and cannot be driven over, and there are problems such as cleaning omissions.
