Example 1
As shown in fig. 1 to 8, a sweeping robot provided by an embodiment of the present application includes: laser radar device 30, sweeper body 10 and infrared ranging device 20, wherein:
the lidar device 30 is mounted on top of the sweeper body 10. The laser radar device 30 rotates and detects a cleaning area by emitting a laser beam during the operation of the robot to detect an area located at a circumference of an outer ring of the robot to construct a cleaning area map, thereby performing cleaning path planning of the robot.
The infrared ranging apparatus 20 is mounted on top of the lidar apparatus 30.
In the working process of the sweeping robot provided by the embodiment of the application, the laser radar device 30 and the infrared ranging device 20 are synchronously started, and the laser radar device 30 detects whether an obstacle exists in the field 10 of the sweeping robot in a long distance; the infrared ray receiving and transmitting assembly in the infrared ray ranging apparatus 20 emits infrared rays, and the reflected infrared rays are received by the infrared ray receiving and transmitting assembly, thereby detecting whether an object exists in the close range of the sweeper body 10 and detecting the distance between the object and the sweeper body, so that the sweeping robot can change the sweeping route to avoid collision with the object.
In addition, since the infrared ranging device 20 is provided at the top of the laser radar device 30, it is possible to detect whether or not an object is present in front of the area above the top of the sweeper body 10 and the distance between the object and the sweeper body 10, and by reasonably setting the distance threshold, the sweeping area of the sweeper robot can be enlarged. So set up, infrared ranging device 20 detects and closely has the barrier in its dead ahead, then the bottom of this object of explanation exists certain space, and the height in this space is higher than the height of laser radar device 30, and it can get into this space to explain the machine body 10 of sweeping the floor, can avoid the laser radar device to receive the striking simultaneously, then steerable robot of sweeping the floor continues to move forward a certain distance, turns to before the robot of sweeping the floor appears striking to can clean further to this object bottom.
For example, when a sofa is placed in front of the robot for cleaning, there is a certain space at the bottom of the sofa, specifically, the height of the gap in the partial area of the bottom of the sofa near the outside is greater than the height of the laser radar device 30, and the gap in the area inside the bottom of the sofa is lower than the height of the laser radar device 30, when the robot for cleaning 10 moves to the edge of the sofa, the controller controls the robot for cleaning 10 to continue to move toward the area inside the bottom of the sofa because the infrared ranging device 20 detects that the space in front of the robot for cleaning 10 is enough for the entrance of the robot for cleaning 30 to not generate impact.
Therefore, the sweeping robot provided by the application can ensure that the sweeping machine body 10 enters the gap at the bottom of the object to further sweep, meanwhile, the laser radar device 30 does not collide, and the route is changed before collision so as to sweep the bottom of the object with the gap at the bottom more further, thereby expanding the sweeping range of the sweeping robot and leading the sweeping effect of the sweeping robot to be better.
The infrared ranging device 20 includes an infrared transceiver and a lens 23, wherein the infrared rays emitted by the infrared transceiver pass through the lens 23 and then are emitted, the reflected infrared rays pass through the lens 23 and then are received by the infrared transceiver, and at least a part of the lens 23 is located at one side of the infrared transceiver facing the moving direction of the sweeper body 10. That is, the infrared ray emission direction of the infrared ray transmitting-receiving unit and the emission direction of the laser beam emitted from the laser radar device 30 have the same region.
Specifically, the infrared transceiver assembly includes an infrared transmitter 25 and an infrared receiver 26, the infrared transmitter 25 is used for transmitting infrared rays, the infrared receiver 26 is used for receiving infrared rays, and the distance between the front object and the sweeping robot is calculated according to factors such as a time difference between the transmission and the reception of the infrared rays.
In a specific implementation manner provided in this embodiment, the sweeping robot includes a casing, a dust collecting box 11 is disposed inside the casing, a sweeping edge brush 13 is disposed at the bottom of the casing, an infrared ranging device 20 is disposed at the top of the casing, and an operation key 12 is also disposed at the top of the casing.
In an alternative embodiment, the level of the infrared rays emitted from the infrared ranging device 20 (shown by the dotted line A-A in fig. 4) is parallel to the level of the laser beam emitted from the laser radar device 30 (shown by the dotted line B-B in fig. 4), and since the infrared ranging device 20 is located on top of the laser radar device 30, the infrared emission track of the infrared ranging device 20 is located above the track of the laser beam emitted from the laser radar device 30. The laser radar device 30 is used for detecting a far area, and the infrared ranging device 20 is used for detecting a near area and is positioned above the sweeper body 10 and the laser radar device 30.
When the infrared ray emission trajectory of the infrared ray ranging apparatus 20 is parallel to the trajectory of the laser beam emitted from the laser radar apparatus 30, the shortest distance between the infrared ray emission trajectory of the infrared ray ranging apparatus 20 and the trajectory of the laser beam emitted from the laser radar apparatus 30 is 10mm to 13.5mm.
In any of the above embodiments, further, the minimum wavelength of the infrared rays emitted from the infrared ranging device 20 is the distance between the lens 23 and the vertical plane of the front end surface of the sweeper body 10 in the moving direction. That is, the shortest wavelength of the infrared rays emitted from the infrared ranging device 20 is the length from the lens 23 to the front end surface of the sweeper body 10, where the front end surface of the sweeper body 10 is the end surface of the sweeper body 10 located at the foremost side in the moving direction.
In a preferred implementation of the present embodiment, the infrared ranging device 20 is mounted at the rear side of the movement direction of the sweeper body 10 and is located at the edge region of the sweeper body 10. It should be noted that, in the present embodiment, both the front side and the rear side are determined for the moving direction of the sweeping robot. The cleaning side brush 13 is located at a front side region of the bottom of the sweeper body 10, and the infrared ranging device 20 is installed at a rear side region of the top of the sweeper body 10.
In a preferred implementation manner of this embodiment, the infrared ranging device 20 further includes a protective housing, the protective housing includes an upper cover 21 and a lower cover 22, the lens 23 is installed between the upper cover 21 and the lower cover 22, the upper cover 21, the lower cover 22 and the lens 23 enclose a sealed chamber, and the infrared transceiver assembly is installed in the sealed chamber. The setting can avoid the infrared ray receiving and transmitting assembly to fall ash, meet water or receive the collision to play better guard action to the infrared ray receiving and transmitting assembly, extension infrared ray receiving and transmitting assembly's live time.
The connection between the upper cover 21 and the lower cover 22, the connection between the upper cover 21 and the lens 23, and the connection between the lower cover 22 and the lens 23 are all sealed, and specifically, the sealing is performed by coating sealant or adding sealing strips.
Further, the top surface of the upper cover 21 is a curved surface, specifically, the longitudinal section of the top surface of the upper cover 21 is an arc line protruding upwards, so that the appearance of the sweeping robot is more attractive.

That is, the edge of the upper cover 21, and the edge of the lower cover 22 are each in a more forward position relative to the lens 23. Therefore, even if a collision occurs, the upper cover 21 and the lower cover 22 are brought into contact with the collided object first, thereby preventing the lens 23 from being directly impacted to protect the lens 23.
In another embodiment of the present example, the side of the lens 23 facing the outside of the sealed chamber is concave surface recessed inward. The edge of the lens 23 may be connected to the inner side areas of the edges of the upper cover 21 and the lower cover 22 as described above, or the edge of the lens 23 may be connected to the edges of the upper cover 21 and the edges of the upper cover 21. Since the outer side surface of the lens 23 is a curved surface recessed into the sealed chamber, the outer side surface of the lens 23 is entirely located in the rear side areas of the edges of the upper cover 21 and the lower cover 22, thereby protecting the lens 23.
In any of the above embodiments, further, the distance between the center point of the lens 23 and the upper surface of the sweeper body 10 in the vertical direction is 17mm to 20mm.
In the above embodiment, the infrared emission directions of the infrared ranging device 20 are fixed and all face the front of the moving direction of the sweeping robot, and in another alternative implementation of this embodiment, the infrared ranging device 20 further includes a first driving structure, and the infrared transceiver component is connected to the first driving structure, where the first driving structure is used to drive the infrared transceiver component to rotate. For example, the first driving structure includes a driver and a turntable, the infrared transceiver is mounted on the turntable, and the driver is connected with the turntable and is used for driving the turntable to rotate, thereby driving the infrared transceiver to rotate.
Further, the infrared ranging device 20 further includes a second driving structure, which is connected to the infrared transceiver and is used for driving the infrared transceiver to swing up and down, so as to change the pitch angle of the infrared rays emitted by the infrared transceiver.
In a preferred embodiment, the infrared ranging apparatus 20 includes a first driving structure and a second driving structure, the second driving structure is mounted on a rotating portion (such as a turntable) of the first driving structure, the infrared transceiver assembly is connected to the second driving structure, the first driving structure drives the second driving structure to rotate so as to drive the infrared transceiver assembly to rotate, so as to change an emission angle of infrared rays in a horizontal direction, and the second driving structure drives the infrared transceiver assembly to swing up and down, so as to change a pitch angle of the emitted infrared rays.
After the robot enters a narrow space, the emission angle of the infrared rays can be changed through the first driving mechanism and/or the second driving mechanism so as to measure the environment in different areas around the main body of the sweeper, and therefore a more preferable sweeping path is provided.
When the infrared ranging device 20 includes the first driving structure, the cross section of the lens 23 may be arc-shaped or ring-shaped, so as to ensure that the infrared rays emitted by the rotated infrared transceiver assembly can always be emitted through the lens 23.
