Description

Technical Field

[0001] This utility model relates to the field of ground cleaning technology, and in particular to an environmentally friendly ground cleaning machine navigation device. Background Technology

[0002] Robotic vacuum cleaners are mobile floor cleaning devices that automatically plan their movement paths to clean floors within a room. They utilize navigation devices based on collision sensors and lidar to perceive the environment, enabling them to plan and adjust their paths within the room, thus achieving home cleaning.

[0003] When existing floor cleaning machines rely solely on lidar and collision sensors to perceive the indoor environment, they are easily trapped and hindered when encountering tangled cables on the ground during movement. This makes it difficult to effectively identify obstacles, resulting in a waste of the floor cleaning machine's electrical energy and water. Utility Model Content

[0004] The purpose of this utility model is to provide an environmentally friendly floor cleaning machine navigation device to solve the problem that existing floor cleaning machine navigation devices cannot fully perceive the indoor environment.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an environmentally friendly ground cleaning machine navigation device, comprising:

[0006] The cleaning machine body is equipped with a lidar and a depth camera is installed on the front side of the cleaning machine body;

[0007] The cleaning module includes a spray head, a drive motor, and a wiping arm. The spray head is located below the depth camera and faces the depth camera. The spray head is connected to the water tank of the cleaning machine body through a water supply pipe. The drive motor is located inside the cleaning machine body. The output shaft of the drive motor is connected to the wiping arm. The wiping arm has a wiping component on the side facing the depth camera, and a squeegee is also provided on one side of the wiping arm.

[0008] As a further description of the above technical solution:

[0009] The cleaning machine body has three protruding seats arranged circumferentially on its side wall, and the three protruding seats are equidistant from each other. The spray head is set on the protruding seats.

[0010] As a further description of the above technical solution:

[0011] Three photoelectric sensors are also installed at the bottom of the cleaning machine.

[0012] As a further description of the above technical solution:

[0013] One photoelectric sensor position corresponds to one protruding seat.

[0014] As a further description of the above technical solution:

[0015] The protruding seat extends upward at an angle.

[0016] As a further description of the above technical solution:

[0017] The wiper blade is a rubber wiper blade.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] 1. In this utility model, to improve the environmental perception capability of the cleaning machine, a depth camera is added to the navigation device of the ground cleaning machine to collect environmental information and identify obstacles. Simultaneously, to prevent contamination or obstruction of the depth camera lens, the spray head obtains cleaning fluid from the water tank of the cleaning machine and sprays it towards the depth camera. After spraying, a drive motor drives the wiping arm to rotate and wipe the front of the depth camera lens, effectively ensuring the environmental information perception effect.

[0020] 2. In this utility model, the cleaning fluid sprayed on the front side of the depth camera lens is wiped clean by a sponge, cloth or other wiping device on the inside of the wiping arm. After the wiping device wipes the depth camera lens, the squeegee on the wiping arm scrapes off the cleaning fluid on the front side of the lens to avoid liquid residue. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please see Figure 1-5 This utility model provides a technical solution: an environmentally friendly ground cleaning machine navigation device, comprising:

[0032] The cleaning machine body 1 is equipped with a lidar 11, and a depth camera 12 is installed on the front side of the cleaning machine body 1. The depth camera is a camera with a 3D depth sensor.

[0033] The cleaning module includes a spray head 2, a drive motor, and a wiping arm 3. The spray head 2 is located below the depth camera 12 and faces the depth camera 12. The spray head 2 is connected to the water tank of the cleaning machine body 1 through a water supply pipe. The drive motor is located inside the cleaning machine body 1. The output shaft of the drive motor is connected to the wiping arm 3. The wiping arm 3 has a wiping component 31 on the side facing the depth camera 12, and a squeegee 32 is also provided on one side of the wiping arm 3.

[0034] The squeegee 32 is a rubber squeegee that fits the surface of the cleaning machine body 1, providing good squeegee effect and preventing scratches on the surface of the cleaning machine body 1.

[0035] Working Principle: To enhance the environmental perception capabilities of the cleaning machine body 1, a depth camera 12 is added to the navigation device of the ground cleaning machine to collect environmental information and identify obstacles. Simultaneously, to prevent contamination or obstruction of the depth camera lens, the spray head 2 obtains cleaning fluid from the water tank of the cleaning machine body 1 and sprays it towards the depth camera 12. After spraying, the drive motor drives the wiping arm 3 to rotate and wipe the front of the depth camera lens, effectively ensuring the environmental information perception effect. The cleaning fluid sprayed on the front of the depth camera lens is wiped clean by the sponge, cloth, or similar wiping components 31 on the inner side of the wiping arm 3. After the wiping components 31 wipe the depth camera lens, the squeegee 32 on the wiping arm 3 scrapes off the cleaning fluid in front of the lens, preventing liquid residue.

[0036] Example 2

[0037] Based on the above embodiments, this embodiment further improves upon the following technical solution: three protruding seats 13 are arranged along their circumference on the side wall of the cleaning machine body 1. The three protruding seats 13 are arranged at equal intervals, and the spray head 2 is disposed on the protruding seats 13.

[0038] The protruding seat 13 hides and protects the spray head 2 and the depth camera 12, effectively preventing damage to the spray head 2.

[0039] Example 3

[0040] This embodiment further improves upon the above embodiment by providing the following technical solution: three photoelectric sensors 14 are also provided at the bottom of the cleaning machine body 1. The navigation device of the cleaning machine body 1 is equipped with photoelectric sensors 14, which detect the distance between the bottom of the cleaning machine body 1 and the ground.

[0041] When one of the photoelectric sensors 14 detects that the distance between the machine and the ground exceeds the set value, the cleaning machine body 1 stops moving to avoid "stepping into the air" and falling, thus further improving the environmental perception capability.

[0042] In addition, each photoelectric sensor 14 position corresponds to a protrusion 13, which not only marks the position of the photoelectric sensor 14, but also forms a protection for the photoelectric sensor 14.

[0043] Example 4

[0044] Based on the above embodiments, this embodiment further improves upon the following technical solution: the protruding seat 13 extends upward at an angle, and the end of the protruding seat 13 is spherical, which effectively avoids scratching the furniture surface caused by the end of the protruding seat 13, while improving the deformation resistance of the protruding seat 13.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
