Generally speaking, it is a robot that can complete cleaning, vacuuming, and mopping work.

[0003] In the prior art, floor sweeping robots often need to use radar for obstacle detection. The outer shape of the radar cover of the existing floor sweepers on the market is generally hollow, with 3 to 4 or more columns around it. First, the appearance is not good-looking. Second, after having columns, there will be some areas that the radar cannot detect and noise points will appear, which will affect data collection, making the collected data inaccurate. Moreover, debris can easily enter the hollow radar cover, and it cannot play a role in protecting components such as the radar.

[0004] Moreover, the existing radar covers on the market do not have anti-collision detection, and are easily damaged during collisions, increasing the user's usage risk and maintenance cost. Summary of the Invention

[0029] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not used to limit the present utility model.

[0030] Embodiment

[0031] As Figures 1-6 shown, this embodiment provides a radar device for a floor sweeping robot with collision detection, including a radar base 6, a housing 8 and a radome 2. Among them, the radar base 6 is arranged inside the housing 8;

[0032] Specifically, the end of the radar base 6 located inside the housing 8 has a protrusion 61. Among them, a plurality of return springs 5 are arranged between the protrusion 61 and the housing 8, and a plurality of touch switches 7 are also arranged on the protrusion 61. Specifically, when the radome assembly (radome 2) touches an object, the radar cover assembly (top cover 1) will move (the radar cover assembly and the housing are not rigidly connected and can have a small displacement in the horizontal direction). When it moves to a certain distance, it will touch the touch switch and will be sensed by the robot at the same time, and the machine will move in the opposite direction. At this time, under the action of the elastic force of the return spring, the radar cover assembly resets. As Figure 7 shown, there are also installation posts between the housing 8 and the return spring 5, which limit the return spring 5 and also facilitate the return spring 5 to drive the radar cover assembly to reset.

[0033] An installation bin 81 is arranged on the housing 8. Among them, the radar base 6 is arranged inside the installation bin 81.

[0034] A radar 3 is installed inside the radar base 6. Among them, a radome 2 is installed on the radar 3. In this embodiment, the radome 2 is made of an acrylic plate. The semi-transparent radome avoids the existence of columns, avoids the problems of detection blind spots and noise points, and improves the accuracy of data collection. Moreover, a top cover 1 is installed at the end of the radome 2. The fully enclosed radome avoids the situation of sundries entering and can protect the components of the radar.

[0035] A fixing bracket 4 is also arranged between the radar 3 and the radar base 6.

[0036] This embodiment also provides a floor sweeping robot with a radar device for a floor sweeping robot with collision detection as described above, and the housing 8 is installed on the floor sweeping robot.

[0037] The radar device of the present utility model is completely enclosed. The semi-transparent radome avoids the existence of columns, eliminates the problems of detection blind spots and noise points, and improves the accuracy of data collection. Moreover, the fully enclosed radome prevents foreign objects from entering and can protect the components of the radar. It is equipped with a reset spring and a tactile switch, enabling collision detection and reset, which is safer.

[0038] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. Without departing from the spirit and scope of the present utility model, various changes and improvements will occur to the present utility model, and all these changes and improvements fall within the scope of protection required by the present utility model. The scope of protection required by the present utility model is defined by the appended claims and their equivalents.
