Autonomous mobile devices are increasingly used in industrial sites, among which lidar navigation technology accounts for a large proportion.

[0003] However, most industrial environments cannot be dust-free. There are a large number of particles in the air. These tiny particles include dust, smoke, water droplets, etc. They will scatter, absorb, reflect, refract, etc., thus affecting the propagation and reception of radar signals.

[0004] In the related art, dust removal on the radar surface is usually performed manually or by using a servo or motor to drive a dust removal device to remove dust from a specific position on the radar. However, the above dust removal methods are inefficient and costly. Utility Model Content

[0005] The utility model aims to at least solve or improve the technical problem of high dust removal cost of radar in the prior art.

[0006] To this end, a first embodiment of the present invention provides a dust removal device.

In addition, through the setting of the bent pipe, the air flow discharged by the guide member can act on the surface of the radar to the greatest extent, thereby improving the dust removal effect of the dust removal device.

[0046] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0047] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0048] Refer to the following Figures 1 to 7 To describe the dust removal device 100, the radar assembly 200 and the autonomous mobile device provided according to some embodiments of the present invention.

[0049] like Figure 1 As shown, according to the first aspect of the embodiment of the utility model, the utility model provides a dust removal device 100, which is used to remove dust on the radar 210, so as to ensure the transmission and reception of the scanning signal of the radar 210.

[0050] The dust removal device 100 includes an air pipe 110, a flow guide 120 and an air source assembly 130. The air pipe 110 and the air source assembly 130 are connected, and the air source assembly 130 can supply air to the air pipe 110. The air pipe 110 includes a curved pipe 112, and the curved pipe 112 is arranged around the radar 210. Figure 2 As shown, at least one guide member 120 is arranged on the pipe wall 114 of the curved pipe 112, and the guide member 120 is arranged toward the radar 210. Therefore, when the air source component 130 supplies air to the air supply pipe 110, the air flow can be blown toward the radar 210 through the guide member 120 to achieve the dust removal effect.

[0051] The dust removal device 100 provided by the utility model is used to remove dust on the radar 210. The dust removal device 100 includes an air pipe 110, a flow guide 120 and an air source assembly 130. The air pipe 110 includes a curved pipe 112. The curved pipe 112 can be arranged around the radar 210. The flow guide 120 is arranged on the pipe wall 114 of the curved pipe 112, and then the flow guide 120 faces the radar 210. The air source assembly 130 is connected to the air pipe 110, and the air source assembly 130 can supply air to the air pipe 110.

[0052] When the air source component 130 supplies air to the air pipe 110, the air flow is transmitted through the air pipe 110 and then ejected by the guide member 120. The air flow ejected by the guide member 120 blows onto the radar 210, thereby blowing off the dust on the radar 210 and removing the dust from the radar 210. In addition, through the setting of the bent pipe 112, the air flow discharged from the guide member 120 can act on the surface of the radar 210 to the greatest extent, thereby improving the dust removal effect of the dust removal device 100.

[0053] Furthermore, dust removal can be achieved through the air delivery pipe 110 and the guide member 120, without the need to set up devices such as steering gears or motors, thereby reducing the cost of the dust removal device 100 and making the dust removal device 100 have a higher dust removal effect. In addition, through airflow dust removal, a contactless dust removal method can be achieved, reducing damage to the radar 210.

[0054] The air source component 130 may be an air pump or a compressor, etc. For example, the air source component 130 may be an adjustable speed air pump.

[0055] Optionally, the flow guiding direction of the flow guiding member 120 is fixed, or the flow guiding direction of the flow guiding member 120 is adjustable.

[0056] The radar 210 includes a scanning surface 212 , and the airflow radiation range of all the air guides 120 covers the scanning surface 212 .

[0057] like Figure 1 As shown, in some embodiments, optionally, the bend 112 is an arc-shaped air pipe, and the value range of the central angle A1 of the bend 112 is greater than or equal to 280 degrees and less than or equal to 320 degrees, that is, 280 degrees ≤ A1 ≤ 320 degrees.

[0058] In this embodiment, since the scanning range of the radar 210 is usually between 0 degrees and 270 degrees, the bend 112 is set to be an arc shape and is only set for the scanning range of the radar 210, thereby reducing the length of the gas pipe 110, reducing costs, and ensuring the dust removal effect of the radar 210.

[0059] In addition, the central angle of the curved pipe 112 has a value range greater than or equal to 280 degrees and less than or equal to 320 degrees, that is, the central angle of the curved pipe 112 is slightly larger than the scanning range of the radar 210, thereby ensuring that the position of the guide member 120 can match the scanning position of the radar 210, thereby reducing the possibility of blind spots in the dust removal device 100.

[0060] Optionally, the central angle A1 of the elbow 112 may be 280 degrees, 290 degrees, 300 degrees, 310 degrees or 320 degrees, etc.

[0061] like Figure 1 As shown, in some embodiments, optionally, a plurality of flow guides 120 are disposed on the curved pipe 112 , and the plurality of flow guides 120 are spaced apart and evenly disposed on the curved pipe 112 .

[0062] In this embodiment, there are multiple flow guide members 120, so that each flow guide member 120 only corresponds to a certain cleaning range, and the multiple flow guide members 120 are evenly arranged on the curved pipe 112, reducing the possibility of dead corners in the dust removal device 100, and the multiple flow guide members 120 are dispersedly arranged to reduce the total number of the flow guide members 120 and reduce the cost of the dust removal device 100.

[0063] Optionally, the number of the guide members 120 can be 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 or 15, etc. Specifically, the number of the guide members 120 can be determined according to the volume of the radar 210, the size of the guide member 120 and the distance between the guide member 120 and the radar 210, which can be obtained through experiments or calculations.

[0064] like Figure 3 As shown, in some embodiments, optionally, the dust removal device 100 further includes a controller 140, and the controller 140 is in communication with the radar 210. The dust removal signal and / or safety signal emitted by the radar 210 can be transmitted to the controller 140, so that the controller 140 controls the air source assembly 130 to work according to the dust removal signal and / or safety signal. Optionally, the safety signal is a signal output by the installation device, and can be an output signal of an output signal switching device (OSSD, Output Signal Switching Device).

[0065] In this embodiment, the dust removal device 100 also includes a controller 140, which is communicatively connected to the radar 210. The controller 140 can control the operation of the air source component 130 according to the dust removal signal emitted by the radar 210, and / or the controller 140 can also control the operation of the air source component 130 according to the safety signal of the radar 210, so that the controller 140 controls the air source component 130 to supply air to the air pipe 110 only when needed, thereby reducing energy consumption and ensuring the dust removal effect of the dust removal device 100.

[0066] Optionally, the controller 140 may be an industrial personal computer (IPC), a processor or a programmable controller, etc.

[0067] Among them, the radar 210 itself has dust detection logic. When the radar 210 detects that the accumulated dust on it reaches a threshold, it will alarm, thereby outputting a dust removal signal to the controller 140. The controller 140 controls the air source component 130 to operate in response to the dust removal signal, so that the dust removal device 100 removes the dust on the radar 210.

[0068] Specifically, Figure 4 As shown, the controller 140 and the radar 210 are communicatively connected, the radar 210 can output a dust removal signal to the controller 140, and the controller 140 can control the switch element 150 to operate, thereby making the gas source component 130 work. The gas source component 130 compresses the gas, and after the gas flow passes through the gas pipe 110, it is ejected toward the radar 210 by the guide member 120, thereby realizing dust removal for the radar 210.

[0069] Since dust may accumulate locally on the radar 210 , in this case, the dust warning of the radar 210 itself may fail.

[0070] However, the safety signal of the radar 210 is more sensitive to dust. When dust accumulates locally on the radar 210, the output signal of the OSSD of the radar 210 will flash off. The dust accumulation situation of the local area of ​​the radar 210 can be judged through the flashing mechanism.

[0071] like Figure 5 As shown, when the safety signal of radar 210 is disconnected and set to 0, check whether the safety signal will be restored within 2 seconds. If not, it indicates that there is an obstacle causing OSSD to be set to 0. At this time, the number of flash disconnections is recorded plus 1. If the safety signal is restored, OSSD is set to 1, and it is determined whether the number of flash disconnections is greater than 5 times. When the number of flash disconnections is less than 6 times, determine whether the safety signal is pulled low again within 30 seconds by OSSD. If it is set to 0 again, repeat the above steps.

[0072] Until the number of flashes reaches the sixth time, the controller 140 controls the switch element 150 to be turned on. After the switch element 150 is turned on, the gas source component 130 compresses the gas. After the gas passes through the gas pipe 110, it is sprayed toward the radar 210 by the guide member 120, thereby realizing dust removal of the radar 210, and the air pump cleans the dust from the radar 210.

[0073] Among them, when the safety signal is not set to 0, the dust removal control is exited, and when the safety signal is restored within 2s, the dust removal control is exited.

[0074] As described above, the above two solutions can be used to judge the accumulation of dust, and both the local accumulation and uniform accumulation of dust on the radar 210 can be accurately judged, thereby improving the dust removal effect of the dust removal device 100 and improving the use efficiency of the radar assembly 200. In addition, the dust removal device 100 is not fully automatic, which saves labor costs.

[0075] like Figure 3 As shown, optionally, the dust removal device 100 further includes a switch element 150 , and the switch element 150 is electrically connected to the controller 140 and the air source assembly 130 , and the controller 140 is used to control the on and off of the switch element 150 .

[0076] In this embodiment, the dust removal device 100 also includes a switching element 150, one end of the switching element 150 is electrically connected to the controller 140, and the other end is electrically connected to the air source component 130. The controller 140 controls the air source component 130 by controlling the on and off of the switching element 150.

[0077] Specifically, the switch element 150 may be a relay or other switches.

[0078] like Figure 1 As shown, in some embodiments, optionally, one end of the gas pipe 110 is connected to the gas source assembly 130, and the other end of the gas pipe 110 is a closed structure.

[0079] In this embodiment, one end of the air pipe 110 is connected to the air source assembly 130, and the other end of the air pipe 110 is a closed structure, so that a single side of the air pipe 110 is connected to the air source assembly 130, thereby reducing the total length of the air pipe 110 and reducing the cost of the dust removal device 100.

[0080] Optionally, the other end of the curved pipe 112 is a closed structure.

[0081] As described above, the dust removal device 100 provided by the present application adopts the connection method of the curved pipe 112 and the guide member 120, which saves the space occupied by the dust removal device 100 and reduces the production cost of the dust removal device 100. In addition, two dust detection schemes can be adopted to automatically identify and clean the local or global dust of the radar 210, thereby improving the automation capability of the dust removal device 100.

[0082] like Figure 6 and Figure 7 As shown, according to the second aspect embodiment of the utility model, the utility model provides a radar assembly 200, including: a radar 210; and a dust removal device 100 provided in any one of the first aspect embodiments, the bend 112 of the air pipe 110 in the dust removal device 100 surrounds the dust removal device 100, and the guide member 120 in the dust removal device 100 faces the radar 210.

[0083] The radar assembly 200 provided by the present invention includes the dust removal device 100 provided in any one of the embodiments of the first aspect, and therefore has all the beneficial effects of the dust removal device 100 provided in any one of the embodiments of the first aspect, which will not be described one by one here.

[0084] like Figure 7 As shown, in some embodiments, optionally, the radar 210 includes a scanning surface 212 , the scanning surface 212 and a portion of the curved pipe 112 are arranged opposite to each other, and the guide member 120 faces the scanning surface 212 .

[0085] In this embodiment, the radar 210 includes a scanning surface 212, and the radar 210 scans through the scanning surface 212. The scanning surface 212 and part of the curved pipe 112 are arranged relative to each other, and the guide member 120 faces the scanning surface 212, that is, part of the curved pipe 112 faces the entire scanning surface 212, thereby ensuring that the guide member 120 removes dust from the entire scanning surface 212, thereby improving the dust removal effect of the dust removal device 100 on the radar 210.

[0086] Among them, Figure 6 As shown, since the central angle A2 of the scanning surface 212 of the radar 210 usually ranges from 0 degrees to 270 degrees, the bend 112 surrounds the scanning surface 212 of the radar 210 and is only set for the scanning range of the radar 210, thereby reducing the length of the gas pipe 110, reducing costs, and ensuring the dust removal effect of the radar 210.

[0087] like Figure 6 As shown, in some embodiments, optionally, the central angle A2 of the scanning surface 212 is smaller than the central angle A1 of the curved tube 112, and the difference between the central angle A2 of the scanning surface 212 and the central angle A1 of the curved tube 112 is greater than or equal to 20 degrees.

[0088] In this embodiment, the central angle A2 of the scanning surface 212 is smaller than the central angle A1 of the curved pipe 112, and the difference between the central angle A2 of the scanning surface 212 and the central angle A1 of the curved pipe 112 is greater than or equal to 20 degrees. This ensures that the dust removal device 100 can remove dust from the entire scanning surface 212 while also reducing the length of the air supply pipe 110 and reducing costs.

[0089] like Figure 7 As shown, in some embodiments, optionally, the radar 210 includes a scanning surface 212, the curved pipe 112 is located above the scanning surface 212, and the guide member 120 is arranged at an angle.

[0090] In this embodiment, the radar 210 includes a scanning surface 212, the curved pipe 112 is located above the scanning surface 212, and the guide member 120 is inclined so that the guide member 120 can discharge airflow from top to bottom, thereby reducing the possibility of dust on the radar 210 being lifted up, reducing the possibility of the radar 210 being contaminated for the second time, and improving the dust removal effect of the dust removal device 100.

[0091] like Figure 6 and Figure 7 As shown, the radar assembly 200 provided in the present application includes a radar 210 and a dust removal device 100, the dust removal device 100 includes an air source assembly 130, an air delivery pipe 110 and a flow guide 120, and the scanning range of the radar 210 is generally 0 degrees to 270 degrees, therefore, the central angle of the bend 112 of the air delivery pipe 110 is set to 300 degrees, the flow guide 120 is evenly distributed on the bend 112, and the flow guide 120 is tilted downward, so that the compressed air can blow away the dust on the scanning surface 212 of the radar 210. Compared with the structure of using a steering gear or a motor in the related art, the present application adopts the method of arranging the flow guide 120 on the bend 112, which has a simple structure, low cost, and low failure rate.
