In the related art, the cleaning robot includes a robot main body, a communication antenna, and a plurality of metal fittings, wherein the communication antenna and the metal fittings are disposed inside the robot main body, and the metal fittings are compactly enclosed in the vicinity of the antenna. Because metal accessories such as wire harnesses, springs, motors, circuit boards and the like are all made of metal materials, the metal accessories can reflect, absorb, shield and the like electromagnetic signals sent by the communication antenna or received by the communication antenna, so that the electromagnetic signals received by the communication antenna from space are weakened or the electromagnetic signals radiated to the space are weakened. Meanwhile, metal fittings inside the robot main body can also serve as interference sources to generate interference signals so as to influence the signal receiving sensitivity of the communication antenna. For example, the common-frequency interference signals generated by circuits or electronic devices on the circuit board and the interference signals generated by the motor during operation are arranged in the robot body, so that the distance between the communication antenna and the interference sources is small, and the interference signals generated by the interference sources are coupled into the antenna receiver from the antenna, so that the receiving sensitivity of the communication antenna is poor. Therefore, the antenna is arranged in the robot main body, and metal fittings in the robot main body have large attenuation interference on electromagnetic signals, so that the coverage range of wireless signals of the antenna is small, and the difference of signals emitted or received by the antenna in different directions is large.

In view of this, as shown in fig. 1, an embodiment of the present application provides an antenna assembly 100, which is externally disposed to a robot body 210 of a cleaning robot 200, and is used as a communication antenna of the cleaning robot 200. This antenna assembly 100 is through all setting up antenna body 110 and radome 120 outside robot main part 210 to protruding in robot main part 210, but not set up in robot main part 210, can keep away from the inside metal fitting of robot main part 210, thereby effectively reduce the signal interference of metal fitting in the robot main part 210 to antenna assembly 100, and then solve the wireless signal coverage of antenna little and the antenna in the big problem of different direction transmission or received signal difference.

The cleaning robot 200 may be a cleaning-ability device such as a sweeping robot, a weeding robot, an underwater cleaning robot, or the like.

Some embodiments of the present application are described in detail below with reference to fig. 1-4. The following embodiments and features of the embodiments may be combined with each other without collision.

The antenna housing 120 is configured to be disposed on the robot body 210 of the cleaning robot 200, for example, the antenna housing 120 is disposed on the top of the robot body 210, and the antenna housing 120 protrudes from the robot body 210, so that the antenna assembly 100 is integrally disposed on the robot body 210, and the interference degree of metal fittings disposed inside the robot body 210 is reduced. The antenna body 110 is located in the antenna housing 120, the antenna body 110 is accommodated in a protection space surrounded by the antenna housing 120 and the robot main body 210, the antenna housing 120 can play a role in protection, for example, when the cleaning robot 200 collides with an obstacle such as a step or a wall body on a supporting surface (such as the ground) in the running process of the supporting surface, the obstacle does not directly collide with the antenna body 110, and when the antenna assembly is collided with the obstacle, the antenna housing 120 can play a role in buffering and protecting the antenna body 110, so that the damage probability of the antenna body 110 is reduced, and the service life of the antenna body 110 is further prolonged.

In this way, when the antenna body 110 transmits and receives electromagnetic signals, the physical attenuation of the electromagnetic signals by the metal fittings in the robot main body 210 can be effectively avoided, so that the radiation efficiency and the signal receiving sensitivity of the antenna assembly 100 are improved, the wireless signal coverage range of the antenna assembly 100 is enlarged, and the difference between the signals transmitted or received by the antenna assembly 100 in different directions is reduced.

Since the radome 120 protects the antenna body 110, for example, when the weeding robot runs, the antenna assembly 100 encounters an obstacle, at this time, the obstacle does not directly collide with the antenna body 110, but contacts the radome 120, thereby reducing the damage degree of the antenna assembly 100 caused by collision and improving the service life of the antenna assembly 100. For another example, when the outdoor rains, the radome 120 can also play a waterproof role and separate the rainwater from the antenna body 110, so that the antenna body 110 cannot suddenly fail due to splashing of the rainwater, the use reliability of the antenna assembly 100 is improved, the service life of the antenna assembly 100 is prolonged, and the weeding robot can travel in the outdoor overcast and rainy weather.

So that the water flow does not enter the area where the metal fittings are installed, and the cleaning robot 200 is allowed to operate normally. In the course of the travel of the bottom wall and the side walls of the swimming pool, the cleaning robot 200 absorbs the garbage such as sludge, fallen leaves, crushed stone, etc. attached to the inner wall of the swimming pool into the accommodating inner shell by the dirt sucking structure. The accommodating inner case may be provided to be detachable such that when the cleaning robot 200 finishes the cleaning operation, the accommodating inner case is detached to discharge the garbage therein.

Moreover, the antenna housing 120 protects the antenna body 110, for example, when the cleaning robot 200 works underwater, the antenna housing 120 can be fixed on the cleaning robot 200 housing 211 through a sealing structure (not labeled), so as to play a role in water prevention, the antenna housing 120 can isolate water flow from contacting the antenna body 110, the water flow can not enter the antenna housing 120, the antenna body 110 is affected, the reliability of the antenna assembly 100 is improved, the service life of the antenna assembly 100 is prolonged, and the cleaning robot 200 can work underwater smoothly.
