Automatic veering structure for floor cleaning apparatus
First Claim
1. An automatic veering structure for a floor cleaning apparatus, comprising:
- a driving wheel set located on the floor cleaning apparatus to control moving direction of the floor cleaning apparatus;
an auxiliary wheel set including a wheel rack hinged on the floor cleaning apparatus, the wheel rack including a wheel rolling on a floor and a first actuation portion, and the wheel rack driving the wheel and the first actuation portion to generate a swivel displacement against the floor cleaning apparatus;
a buffer module including a buffer member at a front side of the floor cleaning apparatus, the buffer member including a second actuation portion extended therefrom and being pushed by an obstacle to drive the second actuation portion to generate a moving displacement against the floor cleaning apparatus;
a detection module to detect the swivel displacement of the first actuation portion and the moving displacement of the second actuation portion and output a corresponding first detection signal and a corresponding second detection signal; and
a control module which is electrically connected to the detection module and receives the first detection signal and the second detection signal to determine whether to trigger the driving wheel set to drive the floor cleaning apparatus to veer,wherein the buffer member includes a movable board located in the floor cleaning apparatus and a blocking board located on the movable board, the movable board and the floor cleaning apparatus being interposed by a bracing member to brace the blocking board at a front position in a normal condition,wherein the floor cleaning apparatus and the movable board include corresponding holding troughs to hold two ends of the bracing member, andwherein the floor cleaning apparatus and the movable board include respectively an insertion portion in the holding troughs to be inserted by the bracing member.

Abstract
An automatic veering structure for a floor cleaning apparatus comprises a driving wheel set to control moving direction of the floor cleaning apparatus, an auxiliary wheel set and a buffer module. It also has a detection module to detect whether the auxiliary wheel set is suspended in the air and whether the buffer module bumps into an obstacle, then output a first detection signal and a second detection signal to a control module to determine whether to trigger the driving wheel set to drive the floor cleaning apparatus to veer to prevent the floor cleaning apparatus from suspending and falling, or stopping moving when encounters the obstacle. Thus the lifespan of the floor cleaning apparatus is lengthened and cleaning efficiency improves.
