Dust collector collision board based on fulcrum conversion

Abstract

The invention discloses a dust collector collision board based on fulcrum conversion, which is mainly composed of a collision board body, a support catch pin, a slide connecting rod, a hinge connecting rod, a cylindrical pin, a taper pin, a V-shaped supporting shoe, a torsional spring and a dust collector chassis. The invention utilizes the fulcrum conversion principle to ensure that the collision board surrounds the fulcrum on the other side to move when any side of the collision board collides in the forward travelling process of the dust collector. The invention is a dust collector collision board structure based on fulcrum conversion, effectively improves the stress situation of the collision board, prevents single-side stress of the collision board and prevents the stuck phenomenon of the collision board when in collision; by fulcrum conversion modes, the invention amplifies the vertical displacement of the collision board and improves displacement pick-up sensitiveness, so that the dust collector collision board can be widely applied to various autonomous mobile dust collectors.

Description

technical field [0001] The invention relates to a collision sensing device for a vacuum cleaner, in particular to a structure of a collision plate of a vacuum cleaner which utilizes the exchange of two fulcrums to improve stress. Background technique [0002] Most of the existing household vacuum cleaners need to be manually operated, which is labor-intensive and time-consuming. In the 21st century, the emergence of an automatic mobile vacuum robot that integrates artificial intelligence has given the world a great surprise, making sweeping fully automated. Automatic vacuum cleaners generally include a collision detection device, which has the function of detecting collision signals. The collision plate can move backward relative to the automatic vacuum cleaner body when encountering an obstacle, so that the automatic vacuum cleaner can sense that there is an obstacle in front, so that the automatic vacuum cleaner can take a backward or turning action. It is driven by its ...

Problems solved by technology

The advantage of this mechanism is that it has better sensitivity. The disadvantage is that when the collision occurs on the other side of the collision plate, there may be a unilateral force, which cannot provide a good restoring force, and the collision plate may be stuck on the The upper cover of the vacuum cleaner; the collision plate of some vacuum cleaners is connected to the chassis by two linkage mechanisms, but there is only one fixed fulcrum. The advantage of this structure is that it can improve the force of the collision plate and avoid the phenomenon of jamming The defect is that it cannot provide a good vertical displacement when a side collision occurs, and there are more or less defects that affect the sensitivity of the displacement sensor, which cannot well meet the various requirements of the vacuum cleaner in the actual cleaning process.
