Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment, and more specifically, to a sweeping machine and a sweeping system. Background Art

[0002] A sweeper is an automatic cleaning device that performs cleaning work on the ground. When working, the dust on the ground is sucked into the dust box inside the sweeper through the exhaust port at the bottom of the sweeper. When the cleaning work of the current area is completed, it moves to the next area to continue working, thereby achieving effective cleaning of the floor inside the house.

[0003] However, when the sweeper is moving, there may be a certain height difference between different areas, so the sweeper will encounter certain height obstacles during the movement. This height obstacle will become difficult to cross due to the height limitation of the sweeper itself, causing the sweeper to be trapped in a certain area and unable to move forward, causing a certain impact on the normal use of the sweeper indoors.

The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0027] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] refer to Figure 1 to Figure 2 The sweeping machine of the present application comprises: a machine body 1, a sensing element 2, a moving component 3 and a lifting component 4;

[0029] The moving component 3 is arranged at the bottom of the body 1, and the lifting component 4 is connected to the moving component 3 and the induction component 2;

[0030] The lifting assembly 4 includes: a gear member 41, a driving member 42 and a rack 43;

[0031] The gear member 41 is fixed in position inside the body 1, the driving member 42 is connected to the gear member 41 in transmission, the rack 43 is connected to the gear member 41 and one end of the rack 43 is connected to the moving component 3, the driving member 42 drives the gear member 41 to rotate according to the sensing signal of the sensing member 2, and the gear member 41 drives the rack 43 to move up and down to push the moving component 3 to perform lifting and lowering activities.

[0032] In this embodiment, when the movable component 3 is installed at the bottom of the body 1, there is an initial height between the bottom of the body 1 and the ground, which is the height of the body 1 for sweeping the floor in the initial state. When the body 1 is lifted, there is a lifting height between the bottom of the body 1 and the ground, which is the height when the body 1 needs to cross obstacles. In this embodiment, the lifting height is at least greater than or equal to 20 mm to facilitate the movable component 3 under the body 1 to cross obstacles. The sensing element 2 is installed at the bottom of the body 1, and is used to sense whether the height of the obstacle currently encountered by the body 1 is greater than or equal to the initial height of the moving component 3. When the sensing element 2 senses that the height of the obstacle currently encountered by the body 1 is greater than or equal to the initial height of the moving component 3, a first sensing signal is generated to control the lifting component 4 to deploy the moving component 3 to the bottom of the body 1, thereby completing the lifting action of the body, so that the body reaches the lifting height to cross the obstacle. When the sensing element 2 senses that the body 1 has crossed the obstacle, a second sensing signal is generated to control the lifting component 4 to retract the moving component 3 from the bottom of the body 1, so as to complete the lowering action of the body 1 and return the body 1 to the initial height.

[0033] In this embodiment, a sweeping machine including a machine body 1, a sensing member 2, a moving assembly 3 and a lifting assembly 4 is provided. When the sensing member 2 installed on the machine body 1 senses that there is an obstacle greater than or equal to the initial height between the machine body 1 and the ground in front of the sweeping machine, a first sensing signal is generated to control the driving member 42 to drive the gear member 41 to rotate. After the gear member 41 rotates, it drives the rack 43 to move downward relative to the gear member 41, so that the moving assembly 3 changes from a retracted state to an extended state, and the height of the machine body 1 relative to the ground is raised to a raised height, thereby realizing the control of the lifting action of the machine body 1, and facilitating the sweeping machine to cross the obstacle; when the sensing member 2 senses that there is no obstacle greater than or equal to the initial height in front of the sweeping machine, a second sensing signal is generated to control the driving member 42 to drive the gear member 41 to rotate in the opposite direction. After the gear member 41 rotates in the opposite direction, it drives the rack 43 to move upward, so that the moving assembly 3 changes from an extended state to a retracted state, and the height of the machine body relative to the ground is lowered to the initial height, thereby realizing the control of the descending action of the machine body 1. This embodiment can effectively control the lifting and lowering of the machine body 1 to facilitate the moving component 3 installed at the bottom of the machine body 1 to cross obstacles.

[0035] In this embodiment, the wheel set 33 is a rolling wheel that contacts the ground with the body 1. When the body 1 is in an initial state of normal operation, the wheel set 33 protrudes from the bottom of the body 1 to contact the ground for rolling. The connecting arm 32 is connected to both sides of the wheel set 33, and is used to unfold or retract the wheel set 33 in the vertical direction. The wheel set shaft 31 is set at the bottom position of the connecting arm 32 away from one end of the wheel set 33, and is used to fix the connecting arm 32 and serve as a center point for the connecting arm 32 to rotate in a predetermined direction.

[0036] In this embodiment, a movable component 3 including a wheel set shaft 31, a connecting arm 32 and a wheel set 33 is set, one end of the connecting arm 32 is movably connected to the wheel set shaft 31, and the other end of the connecting arm 32 is fixedly connected to the wheel set 33. When lifting and lowering activities are required, the connecting arm 32 is rotated around the wheel set shaft 31 to drive the wheel set 33 to be unfolded or retracted, so as to control the lifting and lowering of the wheel set 33, thereby conveniently and effectively completing the lifting and lowering control of the machine body 1.
