[0022] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the embodiments of the present application should fall within the scope of protection of the embodiments of the present application.

[0023] The specific implementation of the embodiment of the present application is further explained below in conjunction with the accompanying drawings of the embodiment of the present application.

[0024] Reference Figure 1-3 The dust pusher device of the embodiment of the present application can be applied to a cleaning device (such as an automatic driving cleaning device) to realize automatic cleaning of a surface to be cleaned. The dust pusher device includes a dust pusher fixing bracket 10, a dust pusher cloth mounting member 20, and a dust pusher cloth 40. The dust pusher fixing bracket 10 is used to connect with the installation object; the dust pusher cloth mounting member 20 is provided with a dust pusher adjustment bracket 24, and the dust pusher adjustment bracket 24 is connected to the dust pusher fixing bracket 10 through a leveling mechanism to adjust the angle of the dust pusher cloth mounting member 20 relative to the dust pusher fixing bracket 10; the dust pusher cloth 40 is installed on the dust pusher cloth mounting member 20.

[0025] The dust pusher fixing bracket 10 of the dust pusher device is used to install the dust pusher cloth mounting member 20 and the dust pusher cloth 40, etc. on the one hand, and is used to connect with the installation object (such as an automatic driving cleaning device) on the other hand, so as to realize the installation of the dust pusher device on the corresponding equipment. The dust pusher cloth mounting member 20 is used to install the dust pusher cloth 40, and the dust pusher cloth 40 is used to clean the surface to be cleaned. A leveling mechanism is provided between the dust pusher adjustment bracket 24 provided on the dust pusher cloth mounting member 20 and the dust pusher fixing bracket 10. The leveling mechanism can be used to adjust the angle of the dust pusher adjustment bracket 24 and the dust pusher cloth mounting member 20, thereby achieving the goal of making the cleaning surface of the dust pusher cloth 40 parallel or in contact with the surface to be cleaned, so as to ensure the cleaning effect, make the dust pusher device more adaptable, and meet the cleaning requirements of the surface to be cleaned at different angles.

[0026] The structural details and working mode of the dust pushing device are described as follows in conjunction with the accompanying drawings:

[0027] Reference Figure 1 and Figure 2 The dust push adjustment bracket 24 can be fixedly mounted on the dust push cloth mounting member 20. The dust push fixing bracket 10 is also fixedly connected to the dust push cloth mounting member 20, and when the dust push adjustment bracket 24 and the dust push fixing bracket 10 are both mounted on the dust push cloth mounting member 20, there is a gap between at least part of the dust push fixing bracket 10 and the dust push adjustment bracket 24.

[0028] In some examples, the leveling mechanism includes an adjustment column 241 and an adjustment member. The adjustment column 241 is disposed on the dust push adjustment bracket 24. A through hole is disposed on the dust push fixed bracket 10. When the dust push fixed bracket 10 is mounted on the dust push cloth mounting member 20, the adjustment column 241 passes through the through hole. The adjustment member can move along the length direction of the adjustment column 241 to adjust the angle of the dust push fixed bracket 10 relative to the dust push cloth mounting member 20 so that the cleaning surface of the dust push cloth 40 is parallel to the surface to be cleaned. In this way, by adjusting the position of the adjustment member on the adjustment column 241, the angle of the dust push adjustment bracket 24 relative to the dust push fixed bracket 10 and the dust push cloth mounting member 20 can be limited, and the relationship between the cleaning surface of the dust push cloth 40 on the dust push cloth mounting member 20 and the surface to be cleaned can be adjusted.

[0029] For example, the adjustment column 241 may be a stud, and the adjustment member may be a nut or other structure that can be threadedly matched with the adjustment column 241 to adjust the position of the adjustment member, and this is not limited.

[0030] In this embodiment, in order to enable the dust pusher device to adapt to some raised obstacles (such as floor lamps, etc.) and ensure that it can pass through the obstacles when there are raised obstacles on the surface to be cleaned, an elastic structure 30 is provided between the dust pusher adjustment bracket 24 and the dust pusher fixed bracket 10.

[0031] For example, the dust push adjustment bracket 24 is provided with an internal thread column 242, and the dust push device further includes a shoulder bolt 60, which passes through the dust push fixing bracket 10 and is threadedly connected to the internal thread column 242, and the elastic structure 30 includes a spring, which is sleeved outside the shoulder bolt 60, and one end of the spring abuts against the dust push adjustment bracket 24, and the other end of the spring abuts against the dust push fixing bracket 10. The spring can ensure that the dust push cloth 40 fits the surface to be cleaned during cleaning, ensuring the cleaning effect. When a low obstacle appears, due to the telescopic characteristics of the spring, the dust push cloth 40 and the dust push cloth mounting member 20 can move, thereby ensuring smooth passage through the low obstacle, achieving the cleaning function without damaging the obstacle and the dust push device.

[0032] Alternatively, if Figure 2 As shown, the first end of the dust pusher cloth mounting member 20 in the width direction (the width direction may be the forward direction or backward direction of the automatic driving cleaning device on which the dust pusher device is mounted when the dust pusher device is in use) is provided with a bent head 21, and the second end of the dust pusher cloth mounting member 20 in the width direction is provided with a bent tail 23 formed by bending upward. It should be noted that the dust pusher cloth mounting member 20 may be provided with only the bent head 21 or only the bent tail 23, or both, without limitation. The bent head 21 and the bent tail 23 are respectively bent upward at a certain angle, so as to protect the dust pusher device when the automatic driving cleaning device moves forward and backward.

[0033] The dust push cloth mounting member 20 is, for example, a dust push cloth mounting plate, which can be made of any of stainless steel plates, carbon steel plates with anti-corrosion surface treatment, aluminum alloy plates, nylon plates, etc. Preferably, the dust push cloth mounting member 20 uses a 3-6 mm aluminum alloy plate, which ensures strength and reduces weight.

[0034] The dust push cloth 40 includes a cloth body and a first limiting structure 41 disposed on the cloth body, and a second limiting structure 211 is disposed on the bending head 21, and the second limiting structure 211 is connected to the first limiting structure 41 of the dust push cloth 40 to limit the cloth body. By providing the bending head 21, at least part of the edge of the dust push cloth 40 can be installed and limited.

[0035] The first limiting structure 41 is, for example, a dust push cloth socket, and the second limiting structure 211 is, for example, a dust push cloth plug, and the two cooperate to achieve the assembly and limiting of the dust push cloth 40.

[0036] In some examples, in order to ensure the flatness of the dust push cloth 40 and avoid wrinkles that affect the cleaning effect, the dust push cloth 40 also includes a first bonding structure 42 arranged on the cloth body, and a second bonding structure 22 is also arranged on the dust push cloth mounting piece 20. The second bonding structure 22 is bonded to the first bonding structure 42 of the dust push cloth 40 so that the cloth body can be detachably covered on the dust push cloth mounting piece 20.

[0037] The first adhesive structure 42 is, for example, the fleece surface of Velcro, and the second adhesive structure 22 is, for example, the hook surface of Velcro, and the dust push cloth 40 is adhered to the dust push cloth mounting member 20 by bonding the two. This mounting method facilitates the installation and replacement of the dust push cloth 40, and can also ensure that the dust push cloth 40 can be laid flat.

[0038] In this embodiment, the first adhesive structures 42 may be distributed at multiple locations of the fabric body to better fix the fabric body.

[0039] Optionally, in order to ensure the structural rigidity of the dust push cloth mounting part 20 in the length direction, avoid deformation in the length direction, and ensure the cleaning effect, the dust push device also includes a reinforcement 50, which is fixedly arranged on the dust push cloth mounting part 20, and the reinforcement 50 extends along the length direction of the dust push cloth mounting part 20.

[0040] The reinforcement member 50 may be a long fixing block, which may be fixed to the dust push cloth mounting member 20 by fasteners such as screws.

[0041] like Figure 4 As shown, a floor cleaning device is provided, which includes a mobile cleaning body 80 and a dust pushing device, the dust pushing device is installed on the mobile cleaning body 80, and the dust pushing device is the above-mentioned dust pushing device. The dust pushing device is installed on the mobile cleaning body 80, so that the mobile cleaning body 80 moves automatically, and drives the dust pushing device thereon to clean the surface to be cleaned (such as the floor) during the movement, thereby realizing automatic cleaning.

[0042] Optionally, a mounting stud 11 is provided on the dust pusher fixing bracket 10 of the dust pusher device, and a mounting hole is provided on the mobile cleaning body, and the mounting stud 11 is used to pass through the mounting hole and be connected to the mounting nut.

[0043] The mounting studs 11 are, for example, welded studs welded on the dust pusher fixing bracket 10. The mounting nuts are, for example, nuts that can be hand-tightened, without limitation. The dust pusher fixing bracket 10 is fixed to the chassis bracket of the mobile cleaning body 80 by the mounting studs and hand-tightened mounting nuts, and the dust pusher mechanism can be disassembled and assembled by loosening or tightening the mounting nuts, which makes assembly and disassembly more convenient.

[0044] In summary, the dust-pushing device can meet the need of cleaning ground dust without turning on the motor and without working noise. It is more suitable for venues with silent requirements. The dust-pushing device itself has an elastic structure. When passing through low obstacles such as floor lamps, it ensures the cleaning function without damaging the floor lamps and the dust-pushing device. It is more suitable for the field of autonomous driving.

[0045] The dust push cloth socket of the dust push cloth 40 is inserted into the bent head 21 of the dust push cloth mounting part 20 to play a limiting role. The dust push cloth is then pasted on the dust push cloth mounting part 20 by Velcro to achieve fitting, thereby limiting and fixing the dust push cloth 40, which is convenient for disassembly and assembly and ensures reliability during dust pushing operation.

[0046] A reinforcing member (such as a reinforcing beam) is installed on the dust push cloth mounting member 20 to ensure that there is no deformation in the entire length range and the ground contact effect is good.

[0047] The dust pusher cloth mounting part 20 is connected and fixed to the dust pusher fixing bracket 10 and the dust pusher adjustment bracket 24 by bolts and anti-loosening nuts, and then fixed to the chassis bracket by the welding studs and hand-tightening nuts of the dust pusher fixing bracket 10, so that the dust pusher device can be disassembled and assembled.

[0048] An elastic structure is provided between the dust pusher fixing bracket 10 and the dust pusher adjusting bracket 24, and the shoulder bolt and the compression spring are connected with the welded internal thread column on the dust pusher adjusting bracket 24 to ensure that some relatively low obstacles can be passed.

[0049] The adjustment column on the dust pusher adjustment bracket 24 passes through the through hole on the dust pusher fixing bracket 10 and is inserted into the adjustment part (such as a lock nut) as an adjustment mechanism. By adjusting the position of the lock nut, the left and right and front and back inclination angles of the dust pusher cloth mounting part 20 can be adjusted to ensure the horizontal state of the entire device in the working state and ensure the fit with the ground, thereby ensuring the cleaning effect.
