Description

Technical Field

[0001] The utility model relates to the technical field of unmanned sweeping robots, and in particular to a radar cleaning device applied to an unmanned sweeping robot and the unmanned sweeping robot. Background Art

[0002] LiDAR is one of the most important recognition devices in autonomous driving for unmanned sweeping robots. Its accuracy directly impacts autonomous driving safety. Currently, the LiDARs on commercially available unmanned sweeping robots are exposed to the environment. During operation, contaminants such as dust, dirt, and ice and snow can adhere to the LiDAR surface. This surface contamination interferes with the LiDAR's scanning and detection, reducing LiDAR recognition accuracy. If the LiDAR surface is not cleaned promptly during operation, it can reduce sensing effectiveness, impacting the robot's safety and even leading to accidents. Therefore, there is an urgent need to install a radar cleaning device to ensure the LiDAR's operational state and thus the safety of unmanned sweeping robots. Utility Model Content

DETAILED DESCRIPTION

[0031] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this utility model.

[0032] It should be noted that the terms "including," "having," and any variations thereof in the embodiments and drawings of this application are intended to cover non-exclusive inclusions. For example, "including" is not limited to the listed structures, but may optionally include structures not listed, or may optionally include other components inherent to those structures.

[0033] The present application discloses a radar cleaning device for an unmanned sweeping robot. This device can clean the surface of a laser radar during the robot's operation, ensuring the laser radar's sensing effect and, in turn, the robot's safety. The following describes each device in detail.

[0034] Figure 1 A radar cleaning device for an unmanned sweeping robot is shown in the figure. Figure 1 As shown, the radar cleaning device mainly includes: a cleaning cover 1, a telescopic device 4, a cleaning water pipe 5, a cleaning nozzle 6, a water pump 8 and a water tank 9, which is hiddenly installed in the radar mounting bridge housing 2 of the unmanned sweeping robot through the cleaning cover 1. The cleaning water pipe 5, the cleaning nozzle 6, the water pump 8 and the water tank 9 are the main components of the radar cleaning device for performing radar cleaning tasks. The water tank 9 is used to store cleaning liquid, and the water pump 8 is used to transport the cleaning liquid in the water tank 9 to the cleaning water pipe 5, and spray it to the surface of the radar 7 to be cleaned through the cleaning nozzle 6. The telescopic device 4 is used to realize the movement of the cleaning water pipe 5 and the cleaning nozzle 6 thereon in a direction perpendicular to the ground, so as to extend the cleaning water pipe 5 and the cleaning nozzle 6 to the outside of the radar mounting bridge housing 2 or retract them into the radar mounting bridge housing 2.

[0035] Specifically, such as Figure 1 As shown, a cleaning port 3 is provided on the radar mounting bridge housing 2 of the unmanned sweeping robot. This port 3 serves as a window through which the cleaning water pipe 5 and cleaning nozzle 6 extend outside the radar mounting bridge housing 2. Correspondingly, a cleaning cover 1 serves as a window cover for the cleaning port 3. Hinged and fixed to the outer surface of the radar mounting bridge housing 2, the cleaning cover 1 is positioned at the cleaning port 3 and completely covers the cleaning port 3, minimizing the risk of dust, dirt, ice, and snow from entering the radar mounting bridge housing 2 through the cleaning port 3, thus providing a dustproof and sealed protection. A telescopic device 4, acting as a telescopic drive for the cleaning end of the radar cleaning device, is provided on the unmanned sweeping robot and located on the side of the radar mounting bridge housing 2 where it connects to the unmanned sweeping robot. It connects to the cleaning water pipe 5 located within the radar mounting bridge housing 2. The cleaning water pipe 5 is fixedly connected to the telescopic end of the telescopic device 4, and the location of the cleaning water pipe 5 corresponds to the location of the cleaning port 3. The telescopic device 4 drives the cleaning water pipe 5 to extend outside or retract inside the radar mounting bridge housing 2. The cleaning nozzle 6 is an important component of the radar cleaning device for performing the radar cleaning task. It is fixedly connected to the water outlet end of the cleaning water pipe 5, and the water outlet direction of the cleaning nozzle 6 is toward the radar 7 installed on the radar mounting bridge housing 2. It should be noted and understood that the "water outlet direction of the cleaning nozzle 6 is toward the radar 7 installed on the radar mounting bridge housing 2" mentioned in this application means that when the radar cleaning device performs the radar cleaning task, the cleaning water pipe 5 and the cleaning nozzle 6 are extended outside the radar mounting bridge housing 2, the cleaning nozzle 6 and the center of the surface of the radar 7 installed on the radar mounting bridge housing 2 are on the same horizontal plane, and the water outlet direction of the cleaning nozzle 6 is facing the surface of the radar 7. When the radar cleaning device is on standby (that is, the radar cleaning task does not need to be performed), the cleaning water pipe 5 and the cleaning nozzle 6 are retracted into the radar mounting bridge housing 2. Although the water outlet direction of the cleaning nozzle 6 is also toward the installation direction of the radar 7, since it is not on the same horizontal plane as the radar 7, the water outlet direction of the cleaning nozzle 6 is not facing the surface of the radar 7 at this time. In addition, the water outlet of the water pump 8 is connected to the water inlet of the cleaning water pipe 5 via a connecting pipe 17, and the water inlet of the water pump 8 is also connected to the water tank 9 via a connecting pipe 17. Therefore, when the radar cleaning device performs a radar cleaning task, the cleaning liquid in the water tank 9 is transported to the cleaning water pipe 5 through the water pump 8 and sprayed through the cleaning nozzle 6 to clean the surface of the radar 7. In the specific implementation process, the water tank 9 and the water pump 8 are both fixedly installed on the unmanned sweeping robot, providing a sufficiently large installation space for the water tank 9.

[0036] like Figure 1 and Figure 2As shown, when the radar cleaning device starts the radar cleaning task, the telescopic device 4 drives the cleaning water pipe 5 and the cleaning nozzle 6 to push open the cleaning cover 1 in the initial position, and extends it to the outside of the radar mounting bridge housing 2 through the cleaning port 3. The water pump 8 is turned on, and the cleaning liquid in the water tank 9 is transported to the cleaning water pipe 5 through the water pump 8, and sprayed to the radar 7 through the cleaning nozzle 6 to clean the radar 7. In the process of the radar cleaning device performing the radar cleaning task, the cleaning cover 1 in this application is always tilted against the cleaning water pipe 5. Figure 1 – Figure 3 As shown, when the radar cleaning device completes the radar cleaning task, the water pump 8 is turned off, and the telescopic device 4 drives the cleaning water pipe 5 and the cleaning nozzle 6 to retract into the radar mounting bridge housing 2 through the cleaning port 3. At the same time, the cleaning cover 1 rotates to the initial position under the action of its own gravity to cover the cleaning port 3.

[0037] In some embodiments, as Figure 1 – Figure 3 As shown, the telescopic device 4 includes an electric push rod 10 and a fixed bracket 11. The electric push rod 10 is installed on the chassis of the unmanned sweeping robot through the fixed bracket 11. The cleaning water pipe 5 is fixedly connected to the telescopic end of the electric push rod 10, so that the cleaning water pipe 5 can move up and down along the specified straight line direction with the electric push rod 10, realizing the telescopic movement of the cleaning water pipe 5 and the cleaning nozzle 6 relative to the inside and outside of the radar mounting bridge housing 2. In the specific implementation process, after the radar cleaning task is started, the electric push rod 10 pushes the cleaning water pipe 5 and the cleaning nozzle 6 upward, and the cleaning water pipe 5 pushes open the cleaning cover 1. When the electric push rod 10 reaches the maximum stroke, the water pump 8 is turned on after 2 seconds, and the radar 7 begins to be cleaned. The water pump 8 is turned off after 60 seconds of cleaning, and then the electric push rod 10 is retracted after 2 seconds.

[0038] In other embodiments, Figure 1 and Figure 3As shown, the radar cleaning device also includes a limiter rope 12. Specifically, one end of the limiter rope 12 is fixedly connected to the radar mounting bridge housing 2, and the other end of the limiter rope 12 is fixedly connected to the end of the cleaning cover 1 away from the hinged end. This limits the maximum opening angle of the cleaning cover 1, ensuring that the cleaning cover 1 always tilts against the cleaning water pipe 5 during the radar cleaning task. This ensures that when the radar cleaning device completes the radar cleaning task, the cleaning cover 1 can rotate to its initial position under the action of its own gravity. Furthermore, the radar cleaning device also includes a magnet 14. The magnet 14 is disposed on the inner surface of the radar mounting bridge housing 2 and is located at the cleaning port 3. When the cleaning cover 1 is in the initial position, the cleaning cover 1 and the radar mounting bridge housing 2 are fixed by adsorption via the magnet 14, ensuring that the cleaning cover 1 will not open due to external shaking during the operation of the unmanned sweeping robot. This improves the stability of the connection between the cleaning cover 1 and the radar mounting bridge housing 2, thereby enhancing its dustproof and sealing protection.

[0039] In a specific embodiment, Figure 1 and Figure 3 As shown, a waterproof platform 13 is provided on the outer surface of the radar mounting bridge housing 2, and the waterproof platform 13 surrounds the cleaning port 3, that is, a circle of waterproof platforms 13 is provided on the outer surface of the radar mounting bridge housing 2 and around the cleaning port 3 to prevent the cleaning liquid from flowing into the interior of the radar mounting bridge housing 2 along the outer surface of the radar mounting bridge housing 2 during the cleaning process of the radar 7. At the same time, correspondingly, the cleaning cover 1 adopts a buckle cover structure compatible with the waterproof platform 13, and the cleaning cover 1 is buckled on the waterproof platform 13. When the cleaning cover 1 is in the initial position, the cleaning cover 1 wraps the waterproof platform 13, thereby covering the cleaning port 3, further improving the sealing of the cleaning port 3.

[0040] In some specific implementation processes, such as Figure 1 and Figure 3 As shown, the cleaning water pipe 5 is an L-shaped stainless steel water pipe. Specifically, the cleaning water pipe 5 includes a vertical portion 15 and a horizontal portion 16 that are perpendicularly connected to each other. The end of the vertical portion 15 away from the horizontal portion 16 is fixedly connected to the telescopic end of the telescopic device 4. The cleaning nozzle 6 is disposed at the end of the horizontal portion 16 away from the vertical portion 15. Therefore, the design of the L-shaped stainless steel water pipe makes the water outlet direction of the cleaning nozzle 6 toward the radar 7. Furthermore, the cleaning nozzle 6 is a high-pressure atomizing nozzle, which improves the cleaning efficiency and cleaning effect of the radar surface.

[0041] The present application also discloses an unmanned sweeping robot. Figure 1 – Figure 3The unmanned sweeping robot includes: an unmanned sweeping robot body, a radar mounting bridge housing 2 installed on the unmanned sweeping robot body, a radar 7 installed on the radar mounting bridge housing 2, and a radar cleaning device applied to the unmanned sweeping robot. The radar cleaning device is the radar cleaning device applied to the unmanned sweeping robot provided in the above embodiment, and its structure and principle are the same as those in the above embodiment. For the sake of brief description, for matters not mentioned in the embodiment of the unmanned sweeping robot, reference can be made to the corresponding content in the above embodiment of the radar cleaning device applied to the unmanned sweeping robot, which will not be repeated here.

[0042] In some embodiments, as Figure 1 and Figure 3 As shown, the radar mounting bridge housing 2 has a trapezoidal structure at one end away from the main body of the unmanned sweeping robot, the radar 7 is mounted on the outer surface of the upper bottom of the radar mounting bridge housing 2, and the cleaning port 3 is provided on one of the waist surfaces of the radar mounting bridge housing 2. With such a structural design, the cleaning liquid after cleaning the radar surface can flow along the two waist surfaces of the radar mounting bridge housing 2 to the ground, avoiding damage to the radar mounting bridge housing 2 due to the cleaning liquid remaining on it.

[0043] To sum up, the present application discloses a radar cleaning device and an unmanned sweeping robot applied to an unmanned sweeping robot. The radar cleaning device adopts a hidden structure, which can not only raise the cleaning water pipe and the cleaning nozzle to a specified height during the operation of the unmanned sweeping robot, and then control the water pump to clean the laser radar surface in time to ensure the sensing effect of the laser radar, thereby ensuring the driving safety of the unmanned sweeping robot, but also can recover the cleaning water pipe and the cleaning nozzle into the radar mounting bridge housing after the electric push rod is retracted after the cleaning is completed, and the cleaning cover can automatically close and attract, playing a role of dustproof sealing protection.
