[0024] Hereinafter, spatially relative terms such as "lower", "above", "upper", "on the side of", "front", "rear", "side" (e.g., as in "side wall"), etc., are used to describe the relationship of one element to another (other) element as shown in the drawings. The spatially relative terms are intended to include different orientations of the device in use, operation, and / or manufacture other than the orientation depicted in the drawings.
[0025] In this application, unless otherwise clearly specified and limited, the terms "connection" and "installation" should be understood in a broad sense. For example, "connection" and "installation" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.
[0026] See also Figure 1-3 The commercial floor scrubber 100 shown is designed to be able to move and turn itself during movement, so that it can clean the floor autonomously during movement. After finishing cleaning, the commercial floor scrubber 100 will return to a docking station (not shown in the figure) to replenish power, replenish cleaning liquid (such as clean water), and remove sewage.
[0027] In the present application, the commercial floor scrubber 100 can be supported above the ground, and the commercial floor scrubber 100 is designed to move in a main moving direction from back to front during operation. The directions mentioned in the following examples are all referenced to this.
[0028] In the present application, the commercial floor scrubber 100 is designed according to three sections, namely a lower section 101, a middle section 102 and an upper section 103; in some embodiments, the heights of the lower section 101, the middle section 102 and the upper section 103 are all approximately 1 / 3 of the overall height of the commercial floor scrubber 100; in some embodiments, the height of the middle section 102 is the highest, the upper section 103 is the second, and the lower section 101 is the lowest.
[0029] The lower section 101 is provided with a mobile chassis 2, a wiping device 4 having a wiping tool 41, and a squeegee device 5 having a squeegee 51. The mobile chassis 2 is used to move on the ground. In order to control the operation, the commercial floor scrubber 100 includes an electric control box 3 ( Figure 4 ). The mobile chassis 2 includes a chassis bracket 20, a pair of front wheels 21 installed at the bottom of the chassis bracket 20, a rear wheel 22, and a pair of driving motors 23. In some embodiments, the pair of front wheels 21 are active wheels and are driven to rotate by the pair of motors 23; the rear wheels 22 are passive wheels. In this example, the pair of front wheels 21 adopts a universal wheel structure, and the driving motor 23 adopts a hub motor.
[0030] The wiping device 4 and the squeegee device 5 can realize cleaning of the floor, and the wiping device 4 is located at the front side of the squeegee device 5. In some embodiments of the present application, the wiping tool 41 is a disc brush that can be driven to rotate. In some embodiments, the squeegee 51 is an arc-shaped structure, which is designed to be able to stick to the floor and be lifted from the floor. In this example, the squeegee device 5 includes a squeegee bracket 50, and the squeegee 51 is supported at the lower part of the squeegee bracket 50; a support wheel 53 is also installed on the squeegee bracket 50. When the squeegee device 5 is working, the support wheel 53 will fall on the floor to be cleaned and can move. When the squeegee device 5 does not need to work, the support wheel 53 will be flipped backwards to leave the floor to be cleaned.
[0031] In addition, the commercial floor scrubber 100 is also provided with a clean water tank 6 for supplying cleaning liquid (such as water, or an aqueous solution with detergent added) to the wiping tool 41, a sewage tank 7 for temporarily storing sewage, and a suction motor 8 for providing suction force for the fluid to enter the sewage tank 7 from the squeegee 51. The cleaning liquid supplied by the clean water tank 6 can wet the floor through the wiping tool 41, and the wiping tool 41 wet-wipes the floor with the help of the cleaning liquid and removes dirt from the floor. The fluid composed of the used cleaning liquid and the dirt on the floor is sucked up by the squeegee 51 and transferred to the sewage tank 7 with the help of the suction motor 8.
[0032] In order to provide electrical energy, the commercial floor scrubber 100 includes at least one rechargeable battery module 9; each energy-consuming component of the commercial floor scrubber 100 is electrically connected to the rechargeable battery module 9. In order to replenish the rechargeable battery module 9, the commercial floor scrubber 100 is provided with an automatic charging port 91 (see FIG. 1 ) which can be electrically connected to an external docking station or a charger device (not shown in the figure). Figure 1 ). After the external docking station or charger device is electrically connected to the automatic charging port 91 , it can charge the rechargeable battery module 9 .
[0033] Therefore, the commercial floor scrubber 100 is a floor scrubber capable of recycling used cleaning liquid. However, the present application is not limited to this type of floor cleaning machine.
[0034] In order to locate and / or navigate within the surrounding environment, the commercial floor scrubber 100 includes a navigation system connected to the electric control box 3 by signal.
[0035] In some embodiments of the present application, the navigation system includes an upper navigation device 11 and a lower navigation device 12. The upper navigation device 11 includes a 3D laser radar module 111, a front camera 112, and a pair of side cameras 113 and 114. The 3D laser radar module 111 can scan the environment around the upper area of the floor scrubber 100 within a 360° range, thereby helping the electric control box to form a navigation map. The front camera 112 and a pair of side cameras 113 and 114 can shoot the ground in front of the floor scrubber 100, so that the electric control box 3 can understand the ground cleaning conditions and obstacles on the ground. The lower navigation device 12 includes a 2D laser radar module 121 and multiple groups of ultrasonic sensors 122. The 2D laser radar module 121 can detect low objects on the front side of the floor scrubber 100. The ultrasonic sensor 122 can better monitor the surrounding area of the floor scrubber 100 at close range. When the upper navigation device 11 and the lower navigation device 12 are working, they can transmit the detected information to the electric control box 3 in time, so as to help the electric control box 3 to better guide the scrubber 100 to move forward.
[0036] like Figure 4 As shown, in some embodiments of the present application, the water suction pipe 52 (see Figure 5 ) The sewage sent into the sewage tank 7 can be reused after being filtered. For this purpose, a plurality of filters (not shown in the figure) are arranged inside the sewage tank 7. After being filtered in the sewage tank 7, the sewage is sent into the clean water tank 6 through the return pipe 77. Thus, circulating water can be realized, which can effectively reduce the volume of the clean water tank 6 carried by the commercial floor scrubber 100, thereby making the structure of the commercial floor scrubber 100 more compact.
[0037] In some embodiments of the present application, the sewage tank 7 and the upper navigation device 11 are distributed in the upper section 103 of the commercial floor scrubber 100, wherein the upper navigation device 11 is located at the front side of the sewage tank 7; the sewage tank 7 defines a part of the outer contour of the upper section 103 of the commercial floor scrubber 100. The clean water tank 6, the rechargeable battery module 9 and the electric control box 3 are arranged at the middle section 102 of the commercial floor scrubber 100; wherein the clean water tank 6 defines a part of the outer contour of the middle section 102 of the commercial floor scrubber 100. The lower navigation device 12, the mobile chassis 2, the wiping device 4 and the squeegee device 5 are all arranged at the lower section 101 of the commercial floor scrubber 100.
[0038] In some embodiments of the present application, the sewage tank 7 includes a tank body 71 and a tank cover 72 located on the top of the tank body 71 and capable of being opened and closed. The tank body 71 of the sewage tank 7 is generally an integral component, such as a plastic material tank body made by injection molding or rotational molding.
[0039] The lower part of the box body 71 has a bottom wall 711. The bottom wall 711 is opposite to the box cover 72 in the upper and lower parts. The suction motor 8, the sewage suction pipeline 52 and the return water pipeline 77 are all mounted on the bottom wall 711. The bottom wall 711 defines a base surface 200. The upper part of the clean water tank 6 provides a support structure, and the sewage tank 7 is mounted on the support structure. A rotating mechanism 75 is arranged between the sewage tank 7 and the upper part of the clean water tank 6. The rotating mechanism 75 is connected to the lower rear part of the box body 71 and the upper rear part of the clean water tank 6 and is configured to allow the sewage tank 7 to rotate relative to the clean water tank 6 around a rotation axis (not shown in the figure) in a first position (see Figure 4 location) and the second location (see Figure 5 In this example, the rotation axis extends left and right in the horizontal direction. In this example, the sewage tank 7 is turned upward from the first position to the second position around the rotation axis relative to the clean water tank 6. In some embodiments, the rotating mechanism 75 can be a hinge mechanism.
[0040] In the first position, the sewage tank 7 is superimposed on the upper side of the clean water tank 6, and the suction motor 8, the sewage suction pipeline 52, and the return water pipeline 77 are all hidden. Most of the suction motor 8, the sewage suction pipeline 52, and the return water pipeline 77 will fall at the middle section 102 of the commercial floor scrubber 100.
[0041] like Figure 5 As shown, the sewage tank 7 is in the second position, and the bottom wall 711 of the sewage tank 7, the suction motor 8, the sewage suction pipeline 52, the return pipeline 77, and the wiring harness 81 connecting the suction motor 8 and the electric control box 3 are all exposed. In this second position, maintenance personnel can easily inspect or replace the suction motor 8 and the fluid pipeline.
[0042] Continue as Figure 4 As shown, a flip bracket 76 is also mounted on the bottom wall 711. The flip bracket 76 is provided with an arc-shaped slide groove 761 and a positioning groove 762 located at one end of the slide groove 761 and connected to the slide groove 761. A pin 62 is provided on the upper part of the water tank 6. When the sewage tank 7 rotates from the first position to the second position, the pin 62 will slide along the arc-shaped slide groove 761; when the pin 62 slides into the positioning groove 762, the sewage tank 7 is maintained in the second position; this can help to stably maintain the sewage tank 7 in the second position, so as to facilitate maintenance personnel to better maintain the commercial floor scrubber 100.
[0043] Continue to see Figure 2 , Figure 3 and Figure 4In some embodiments of the present application, the rear of the upper section 102 has an inclined wall 712. The inclined wall 712 defines the outer contour of the rear of the upper section 103. A display screen 33 capable of being operated is installed at the inclined wall 712. In this example, the inclined wall 712 is defined by the rear of the box body 71. The inclined wall 712 defines a base surface 300. When the sewage tank 7 is in the first position, the base surface 300 where the inclined wall 712 is located forms an acute angle with the horizontal plane 400, and the angle can be selected to be 20°-70°.
[0044] In addition to the display screen 33, the inclined wall 712 is also provided with a pair of gripping handles 74. In some embodiments, the pair of gripping handles 74 are located on the left and right sides of the display screen 33. The pair of gripping handles 74 can facilitate the robot user to manually push the robot to move in special occasions.
[0045] The middle section 102 of the commercial floor scrubber 100 also includes an openable rear cover 1021. The rechargeable battery module 9 is configured to be removed from the middle section 102 after the rear cover 1021 is opened. The electric control box 3 is configured to be exposed after the rear cover 1021 is opened, which can also facilitate the user to inspect and repair the electric control box 3.
