Problems solved by technology

In order to pass small obstacles during operation, the sweeping robot in the related art is usually equipped with a spring-connected lifting wheel. Since the height of the wheel lifting is linearly related to the spring force, the elastic force changes greatly during the lifting process of the wheel, causing the spring to act on the wheel. The force on the top is not easy to control, and there is room for improvement

Abstract

The invention discloses a vacuum cleaner, comprising: a chassis; a driving wheel bracket, the driving wheel bracket is arranged on the chassis and has at least two first matching parts arranged at intervals; a driving wheel, the driving wheel is arranged on the chassis and the height relative to the chassis can be adjusted Adjustment, the driving wheel outer cover is provided with a cover and the driving wheel is rotatable relative to the cover, and the cover is provided with at least two second matching parts adapted to the first matching part; the elastic part is respectively connected with the cover and the The drive wheel bracket is connected, wherein, one of the first matching portion and the second matching portion forms an elongated track portion, and the other of the first matching portion and the second matching portion forms a sliding portion that can move along the track portion, and at least The extending directions of the lengths of the two rail parts are not parallel. According to the vacuum cleaner of the embodiment of the present invention, the lifting height of the driving wheel and the elastic force of the elastic member form a nonlinear relationship, and the force of the elastic member acting on the driving wheel can meet the requirements for driving the vacuum cleaner, so that the vacuum cleaner can pass through the set smoothly. step surface.

Description

technical field [0001] The invention relates to the technical field of cleaning appliances, in particular to a vacuum cleaner. Background technique [0002] At present, sweeping robots widely appear in our lives, and sweeping robots can complete cleaning without the help of users, which is intelligent and convenient. The sweeping robot in the related art is usually equipped with spring-connected lifting wheels in order to pass through small obstacles during operation. Since the lifting height of the wheels is in a linear relationship with the spring force, the elastic force changes greatly during the lifting process of the wheels, causing the spring to act on the wheels. The force on it is not easy to control, and there is room for improvement. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a vacuum cleaner, which runs smoothly and pro...
