[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In the description of the present invention, it should be noted that the terms "vertical direction", "upper", "lower", "horizontal" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0031] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] like Figures 1 to 5 The figure shows the disc brush deflection mechanism of the utility model, which is used to drive the disc brush of the sweeper to deflect to expand the cleaning range. Specifically, it includes a rotor motor 1 and a connecting rod 2. The two ends of the connecting rod 2 are respectively provided with a first mounting position 3 and a second mounting position 4. The first mounting position 3 is fixedly connected to the rotor motor 1, and the second mounting position 4 is used to connect the disc brush. The rotor motor 1 drives the connecting rod 2 to transmit, and the connecting rod 2 drives the disc brush to deflect with the rotor motor 1 as the axis, thereby expanding the cleaning range. A limit assembly 5 is provided on the outside of the rotor motor 1. The limit assembly 5 is used to limit the swing angle of the connecting rod 2, thereby limiting the deflection range of the disc brush.

[0033] In the disc brush deflection mechanism of the present invention, a rotor motor 1 is selected as the power source, and an outer rotor motor 1 or an inner rotor motor 1 is optionally used to connect the connecting rod 2 to the rotor part for transmission. There is no need to use gears for transmission, which simplifies the transmission structure and reduces production costs. At the same time, it can reduce the volume of the overall structure and save equipment space for the sweeping robot.

[0034] Specifically, the rotor motor 1 includes a base 11, a stator assembly 12 mounted on the base 11, a rotating shaft 13 rotatably connected to the base 11, and a rotor assembly 14 connected to the rotating shaft 13; the first mounting position 3 is assembled and connected to the rotor assembly 14. In the working state, the base 11 and the stator assembly 12 remain stationary, the rotor assembly 14 rotates, and the connecting rod 2 then rotates with the rotor assembly 14 as the axis, so that the connecting rod 2 swings.

[0035] Specifically, the limiting assembly 5 includes an integrally formed connection shell 51 and a limiting ring 52, and the connection shell 51 is assembled and connected to the base 11; one end of the connection shell 51 has an opening 53, and the limiting ring 52 is arranged at the opening 53, and the limiting ring 52 is used to limit the swing angle of the connecting rod 2. The connection shell 51 is connected to the base 11, which protects the rotor motor 1 and improves the service life of the rotor motor 1. The connection shell 51 has an opening 53 at one end to avoid air, so that the connecting rod 2 and the rotor assembly 14 can be connected.

[0036] Furthermore, a notch 54 is provided on the limiting ring 52. Figure 2 As shown, the connecting rod 2 always swings within the range of the notch 54. When the connecting rod 2 swings to a certain angle, it interferes with the two side end points of the notch 54 and stops swinging. This limits the swing angle of the disc brush and can prevent multiple disc brushes in the sweeper from colliding and causing damage when they swing at the same time. Figure 2 The middle angle A is the swing angle of the connecting rod 2 in the notch 54, and the angle A is 15-35 degrees. The angle A can be adaptively adjusted according to data such as the spacing between the disc brushes and the number of disc brushes.

[0037] Furthermore, a gap is left between the inner wall of the connecting shell 51 and the rotor assembly 14 to prevent the connecting shell 51 from interfering with the rotation of the rotor assembly 14 and affecting the deflection of the disc brush.

[0038] Specifically, the first mounting position 3 and the second mounting position 4 are both annular connecting rings 31, and assembly holes 32 are provided on the connecting rings 31; the first mounting position 3 is structurally connected to the stator assembly 12 through the assembly holes 32, and the second mounting position 4 is structurally connected to the disc brush through the assembly holes 32. Specifically, in order to improve the connection stability, a plurality of assembly holes 32 are provided, and are distributed on the connecting ring 31 in a circumferential array.

[0039] Also included is a cleaning robot which adopts the disc brush deflection mechanism of the utility model to drive the disc brush to deflect, thereby expanding the cleaning range and improving the cleaning efficiency.

[0040] Compared with the prior art, the disc brush deflection mechanism and cleaning robot involved in the utility model are used to drive the deflection of the disc brush of the sweeper to expand the cleaning range of the sweeper and improve the cleaning efficiency; specifically, they include a rotor motor 1 and a connecting rod 2, one end of the connecting rod 2 is connected to the rotor motor 1, and the other end of the connecting rod 2 is connected to the disc brush, and the rotor motor 1 drives the connecting rod 2 to swing to achieve the deflection of the disc brush; the rotor motor 1 is adopted, and the connecting rod 2 is directly connected to the rotor assembly 14 to achieve transmission, without the need to set up gear transmission, thereby improving the transmission efficiency, simplifying the mechanical structure, and reducing the manufacturing cost; at the same time, a limiting assembly 5 is provided on the outer side of the rotor motor 1, specifically a connecting shell 51 and a limiting ring 52, and the connecting shell 51 is used to protect the rotor motor 1 and increase the service life; a notch 54 is provided on the limiting ring 52, and the swing angle of the connecting rod 2 is limited by the notch 54, thereby limiting the deflection range of the disc brush and avoiding interference between multiple disc brushes; in addition, it also involves a cleaning robot, which expands the cleaning range and improves the cleaning efficiency by offsetting the disc brush.

[0041] The above only expresses the preferred technical solution of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and the utility model is also intended to include these modifications and modifications.
