Abstract
Description
Technical Field
[0001] This disclosure relates to the field of cleaning equipment technology, and in particular to a robot housing, a cleaning robot, and a cleaning system. Background Technology
[0002] Currently, cleaning robots such as sweeping robots and sweeping-mopping robots detect obstacles in their path by having forward and lateral sensors located at the front and right sides of their casing, respectively. Existing cleaning robots typically use line laser modules for both forward and lateral sensing. The forward sensor emits a horizontal line of laser light to detect obstacles in front of the robot, while the lateral sensor emits a vertical line of laser light to detect obstacles to its sides. However, this design creates a blind spot between the forward and lateral sensors. Objects in front of the robot's side are often only detected when they are very close to the lateral sensor. Therefore, when the robot has significant inertia, collisions can easily occur due to delayed avoidance, resulting in poor obstacle avoidance performance. Utility Model Content

[0010] In some embodiments, the first light-emitting aperture is a strip-shaped aperture with a width smaller than the width of the emitting end of the first line laser, and is perpendicular to the side-by-side distribution direction of the first line laser and the first camera module;
[0011] And / or, the outer wall of the first mounting bracket is provided with a first light inlet hole that mates with the first limiting hole, and the first light inlet hole gradually expands from the inside to the outside;

[0015] In some embodiments, the housing further includes a forward sensing device disposed on the side wall at the front end of the housing.
[0016] In some embodiments, the forward sensing device includes a second line laser and a second camera module arranged side by side, the second line laser being located above the second camera module and tilted toward the second camera module.
[0017] In some embodiments, the forward sensing device further includes a second mounting bracket disposed on the side wall of the housing. The inner wall of the second mounting bracket is provided with a second limiting groove and a second limiting hole. The second line laser is inserted and fixed in the second limiting groove, and the second camera module is inserted and fixed in the second limiting hole. The outer wall of the second mounting bracket is provided with a second light-emitting hole that penetrates the bottom surface of the second limiting groove.
[0018] In some embodiments, the second light-emitting aperture is a strip-shaped aperture with a width smaller than the width of the emitting end of the second line laser, and the second light-emitting aperture is inclined downward and perpendicular to the vertical direction;

[0026] The disclosed technical solution for a robot casing, when applied to a cleaning robot, utilizes a lateral sensing device where the first linear laser and the first camera module are arranged side-by-side in an upward-sloping direction. This means the first linear laser is angled, resulting in an angled linear laser beam emitted from its emitting end towards the side of the cleaning robot. The lower end of this angled linear laser beam moves forward a certain distance, reaching a more forward position within the side area of the cleaning robot. During operation, when an object in front of the cleaning robot's side enters the lower illumination range of this angled linear laser (while still some distance from the lateral sensing device), the linear laser beam is reflected by the object to the first camera module. The lateral sensing device then detects the object in front of the side area, allowing it to detect objects earlier. This provides the cleaning robot with more time to prepare for obstacle avoidance, better preventing collisions and effectively improving its obstacle avoidance performance.

[0040] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.
[0041] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this disclosure are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.
[0042] It should also be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.
[0043] Furthermore, the use of terms such as "first" and "second" in this disclosure is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this disclosure.
[0044] This disclosure proposes a robot housing applicable to various mobile robot products, such as cleaning robots like sweeping robots, mopping robots, and combined sweeping and mopping robots, or transport robots and service robots. For a clearer explanation of the technical solution of this disclosure, please refer to [link to relevant documentation]. Figure 11 The embodiments in this disclosure are illustrated using a cleaning robot 100 as an example. The cleaning robot 100 can perform cleaning tasks on the surface to be cleaned, including but not limited to the ground, tabletop, glass surface, roof, door, etc.
[0045] See Figure 1 and Figure 2 In this embodiment, the robot housing includes a housing 10 and at least one lateral sensor. The housing 10 has a front end 11 and a rear end 12 arranged opposite to each other. The front end 11 and rear end 12 of the housing 10 refer to the front and rear ends in the forward direction of the cleaning robot 100, such as the forward direction of the cleaning robot 100 when performing a cleaning task. A lateral sensing device 20 is disposed on the side wall of the housing 10, and the lateral sensing device 20 is located to the right rear or left rear of the front end 11 of the housing 10. In the figures of this embodiment, only one lateral sensing device 20 located to the right rear of the front end 11 of the housing 10 is shown as an example. See [reference needed]. Figure 1 The right side of the housing 10. Of course, in some other embodiments, a lateral sensing device 20 may be provided on the left rear of the front end 11 of the housing 10, or a lateral sensing device 20 may be provided on both the right rear and left rear of the front end 11 of the housing 10, or multiple lateral sensing devices 20 may be provided on the right rear or left rear of the front end 11 of the housing 10.
[0046] The lateral sensing device 20 includes a first line laser 21 and a first camera module 22 arranged sequentially and side-by-side along an upwardly inclined direction F. The first camera module 22 is located on the side of the first line laser 21 near the front end 11 of the housing 10 (also the side of the first line laser 21 that is inclined upwards), that is, the first line laser 21 is arranged side-by-side below the first camera module 22. Furthermore, the emitting end of the first line laser 21 is inclined towards the first camera module 22, so that the linear laser emitted by the first line laser 21 can be received by the first camera module 22 after being reflected by an obstacle. It can be understood that the direction F points from the rear end 12 of the housing 10 to the front end 11 and is inclined away from the surface to be cleaned. The first camera module 22 is closer to the front end 11 of the housing 10 and farther away from the surface to be cleaned than the first line laser 21. For example, when the surface to be cleaned is the ground, the cleaning robot 100 walks on the ground to clean it. The direction F points from the rear end 12 of the housing 10 to the front end 11 and is tilted in the direction away from gravity. The first camera module 22 is closer to the front end 11 of the housing 10 than the first line laser 21, and its height in the direction away from gravity is higher than that of the first line laser 21.
[0047] The technical solution of the robot housing in this embodiment, when applied to the cleaning robot 100 as the housing of the cleaning robot 100, is such that, since the first line laser 21 and the first camera module 22 of the lateral sensing device 20 are arranged side by side in a tilted upward direction F, that is, the first line laser 21 is tilted, the linear laser emitted from the emitting end of the first line laser 21 towards the side area of the cleaning robot 100 is tilted, and the lower end of this tilted linear laser will move forward a certain distance, reaching a more forward position in the side area of the cleaning robot 100; during the operation of the cleaning robot 100, when When an object in front of the side area of the cleaning robot 100 enters the lower illumination range of the inclined linear laser (at which point the object is still a certain distance from the lateral sensing device 20), the linear laser will be reflected by the object to the first camera module 22. The lateral sensing device 20 will then detect the object in front of the side area. In other words, the lateral sensing device 20 can detect the object in front of the side area of the cleaning robot 100 earlier, thus giving the cleaning robot 100 more time to prepare for obstacle avoidance and better avoid collisions, effectively improving the obstacle avoidance performance of the cleaning robot 100.
[0048] See Figure 1 In some embodiments, the housing also includes a forward sensing device 30, which is disposed on the side wall of the front end 11 of the housing 10. The forward sensing device 30 is used to detect obstacles in front of the cleaning robot 100 so that the cleaning robot 100 can avoid obstacles during its movement. The forward sensing device 30 can use a line laser sensor for detection, or an infrared light sensor, or other methods to detect obstacles in front. Furthermore, because the lower end of the line laser emitted by the first line laser 21 of the lateral sensing device 20 moves forward, hitting a more forward position in the side area of the cleaning robot 100, a portion of the detection blind zone between the forward sensing device 30 and the lateral sensing device 20 is covered by the forward-moving line laser, thereby reducing the detection blind zone between the forward sensing device 30 and the lateral sensing device 20 and achieving the effect of reducing the obstacle avoidance detection blind zone of the cleaning robot 100.
[0049] In some embodiments, the lateral sensing device 20 is located closer to the front end 11 of the housing 10 than to the rear end 12 of the housing 10, meaning the lateral sensing device 20 is positioned on the front half of the housing 10. Positioning the lateral sensing device 20 on the front half of the housing 10 not only ensures earlier detection of objects in the side area but also reduces the area between the lateral sensing device 20 and the forward sensing device 30, further reducing the size of the blind spot and improving the obstacle avoidance performance of the cleaning robot 100.
[0050] In existing technical solutions, all sensors of the sensor module (such as line lasers and camera modules) are usually fixed on the PCB (e.g., by soldering or adhesive bonding). However, since the PCB is easily deformed by external forces, when the PCB deforms, the relative positions between the sensors of the sensor module will change, which will lead to a decrease in the detection accuracy of the sensor module or failure of the detection function. Furthermore, there is no structure on the PCB to assist in the positioning of the sensors, resulting in poor sensor installation accuracy, which will also cause a decrease in the detection accuracy of the sensor module or failure of the detection function.
[0051] In view of the defects or deficiencies in the existing technical solutions described above, this embodiment proposes an improved solution for the robot housing, in conjunction with reference to... Figures 3 to 6a In this embodiment, the lateral sensing device 20 further includes a first mounting bracket 23 disposed on the side wall of the housing 10. The inner wall of the first mounting bracket 23 is provided with a first limiting groove 231 and a first limiting hole 232. The first line laser 21 is inserted and fixed in the first limiting groove 231, and the first camera module 22 is inserted and fixed in the first limiting hole 232. The outer wall of the first mounting bracket 23 is provided with a first light-emitting hole 233 that penetrates the bottom surface of the first limiting groove 231 so that the line laser of the first line laser 21 can be emitted. By inserting and fixing the first line laser 21 and the first camera module 22 into the first limiting groove 231 and the first limiting hole 232 of the first mounting bracket 23, respectively, the first mounting bracket 23 can be made of a high-strength material, making it less prone to deformation. This ensures that the positions of the first line laser 21, the first camera module 22, and the first mounting bracket 23 remain relatively fixed, preventing positional changes in the first line laser 21 and the first camera module 22. Furthermore, the first limiting groove 231 and the first limiting hole 232 can provide positioning assistance for the installation of the first line laser 21 and the first camera module 22, ensuring their installation accuracy. Therefore, the detection function and detection accuracy of the lateral sensing device 20 are effectively guaranteed. The insertion and fixing of the first laser 21 to the first limiting groove 231, and / or the insertion and fixing of the first camera module 22 to the first limiting hole 232, can be fixed by applying glue after insertion and installation, or by using a corresponding snap-fit structure during insertion and installation, etc.
[0052] In some embodiments, the first light-emitting aperture 233 is a strip-shaped aperture with a width smaller than the width of the emitting end of the first line laser 21, and is perpendicular to the side-by-side distribution direction of the first line laser 21 and the first camera module 22 (i.e., direction F in the figure). In this embodiment, the first light-emitting aperture 233, by adopting a strip-shaped aperture with a width smaller than the width of the emitting end of the first line laser 21, limits the field of view and emission width of the linear laser of the lateral sensing device 20, and makes the strip-shaped aperture perpendicular to the side-by-side distribution direction F of the first line laser 21 and the first camera module 22, and makes the length direction of the strip-shaped aperture consistent with the direction of the inclined linear laser emitted by the first line laser, ensuring that the linear laser emitted to the side area of the cleaning robot 100 is in an inclined direction. The size of the strip-shaped aperture can be designed according to the specific field of view and emission width requirements of the lateral sensing device 20. In this embodiment, by using the strip-shaped aperture, the field of view and emission width of the linear laser of the lateral sensing device 20 are limited, thus avoiding the situation where the linear laser with an excessively large field of view or width hits other structural components and causes stray light to mix in, thereby affecting the detection and recognition results.
[0053] See Figure 3 and Figure 6a In some embodiments, the outer wall of the first mounting bracket 23 is provided with a first light inlet hole 234 that mates with the first limiting hole 232. The first light inlet hole 234 gradually expands from the inside to the outside to ensure that the opening end of the first light inlet hole 234 is large enough to receive the reflected light signals from each part of the linear laser emitted by the first line laser 21. Understandably, the opening size of the first light-inlet aperture 234 gradually increases along the direction away from the light-inlet. Since the first light-inlet aperture 234 is used to receive reflected light signals, the larger the opening end is, the more reflected light signals the first light-inlet aperture 234 can receive. It should be noted that the opening size of the first light-inlet aperture 234 can be limited according to the opening shape of the first light-inlet aperture 234, and this disclosure does not impose specific limitations on it. For example, if the opening of the first light-inlet aperture 234 is circular, its opening size can be limited by the diameter of the circular opening. Or, for example, if the opening of the first light-inlet aperture 234 is rectangular, its opening size can be limited by the longest side of the rectangle. In other embodiments, the opening shape of the first light-inlet aperture 234 can also be other shapes.
[0054] See Figure 4 and Figure 6aIn some embodiments, the lateral sensing device 20 further includes a first circuit board 24, which is mounted on the inner wall of the first mounting bracket 23. The first circuit board 24 is electrically connected to the first line laser 21 and the first camera module 22. The mounting of the first circuit board 24 on the inner wall of the first mounting bracket 23 keeps the position of the first circuit board 24 relative to the first line laser 21 and the first camera module 22 relatively fixed, and facilitates the electrical connection between the first line laser 21, the first camera module 22, and the first circuit board 24. The first line laser 21 and the first camera module 22 can be electrically connected to the first circuit board 24 via wires, ribbon cables, or a flexible PCB. Furthermore, the first circuit board 24 can be provided with notches to allow for the first line laser 21 and the first camera module 22 to pass through, ensuring that the installation of the first circuit board 24 does not interfere with the installation of the first line laser 21 and the first camera module 22, allowing for a more compact overall structure of the lateral sensing device 20.
[0055] See Figure 6 and Figure 6a In some embodiments, the lateral sensing device 20 further includes a first lens 25, which is disposed on the outer wall of the first mounting bracket 23 and covers the first light-emitting hole 233 and the first camera module 22. By setting the first lens 25 to cover the first light-emitting hole 233 and the first camera module 22, damage to the first line laser 21 and the first camera module 22 by external objects is avoided. At the same time, dust or dirt is prevented from falling onto the emitting end of the first line laser 21 and the receiving end of the first camera module 22, thus protecting the first line laser 21 and the first camera module 22 and making the robot casing more concise and beautiful.
[0056] See Figure 3 and Figure 6a In some embodiments, a first groove 235 is provided on the outer wall of the first mounting bracket 23, and the first lens 25 is adapted to be accommodated in the first groove 235. By providing the first groove 235, the installation and fixation of the first lens 25 are facilitated, and the first lens 25 is also prevented from protruding outward, thus protecting the first lens 25 and making the appearance of the robot shell relatively flat, simpler, and more aesthetically pleasing.
[0057] See 7. Figure 8 and Figure 10aIn some embodiments, the forward sensing device 30 includes a second line laser 31 and a second camera module 32 arranged side by side. The second line laser 31 is located above the second camera module 32 and is tilted towards the second camera module 32, so that the line laser emitted by the second line laser 31 can be received by the second camera module 32 after being reflected by an obstacle. The second line laser 31 detects obstacles in the forward area by emitting a horizontal line laser forward. After the line laser hits an obstacle in front, it is reflected back to the second camera module 32 for reception. It is understood that the second camera module 32 is closer to the surface to be cleaned than the second line laser 31, and the second line laser 31 is tilted towards the direction closer to the surface to be cleaned, that is, it is not set in a horizontal direction. For example, when the surface to be cleaned is the ground, the cleaning robot 100 walks on the ground to clean the ground, and the height of the second line laser 31 in the direction away from gravity is higher than the height of the second camera module 32.
[0058] See also Figure 7 and Figure 10aIn some embodiments, the forward sensing device 30 further includes a second mounting bracket 33 disposed on the side wall of the housing 10. The inner wall of the second mounting bracket 33 is provided with a second limiting groove 331 and a second limiting hole 332. The second line laser 31 is inserted and fixed in the second limiting groove 331, and the second camera module 32 is inserted and fixed in the second limiting hole 332. The outer wall of the second mounting bracket 33 is provided with a second light-emitting hole 333 that penetrates the bottom surface of the second limiting groove 331. In this embodiment, the forward sensing device 30 further includes a second mounting bracket 33 disposed on the side wall of the housing 10. The inner wall of the second mounting bracket 33 is provided with a second limiting groove 331 and a second limiting hole 332. The second line laser 31 is inserted and fixed in the second limiting groove 331, and the second camera module 32 is inserted and fixed in the second limiting hole 332. The outer wall of the second mounting bracket 33 is provided with a second light-emitting hole 333 that penetrates the bottom surface of the second limiting groove 331 so that the line laser of the second line laser 31 can be emitted. By inserting and fixing the second line laser 31 and the second camera module 32 into the second limiting groove 331 and the second limiting hole 332 of the second mounting bracket 33, respectively, the second mounting bracket 33 can be made of a high-strength material to prevent deformation. This ensures that the positions of the second line laser 31, the second camera module 32, and the second mounting bracket 33 remain relatively fixed, preventing positional changes in the second line laser 31 and the second camera module 32. Furthermore, the second limiting groove 331 and the second limiting hole 332 can provide positioning assistance for the installation of the second line laser 31 and the second camera module 32, ensuring the installation accuracy of the second line laser 31 and the second camera module 32. Therefore, the detection function and detection accuracy of the forward sensing device 30 are effectively guaranteed. The insertion and fixing of the second laser 31 to the second limiting groove 331, and / or the insertion and fixing of the second camera module 32 to the second limiting hole 332, can be fixed by applying glue after insertion and installation, or by using a corresponding snap-fit structure during insertion and installation, etc.
[0059] In some embodiments, the second light-emitting aperture 333 is a strip-shaped aperture with a width smaller than the width of the emitting end of the second line laser 31. The second light-emitting aperture 333 is tilted downwards and perpendicular to the vertical direction. In this embodiment, by using a strip-shaped aperture with a width smaller than the width of the emitting end of the second line laser 31, the field of view and emission width of the linear laser of the forward sensing device 30 are limited. Furthermore, the strip-shaped aperture is tilted downwards and perpendicular to the vertical direction, ensuring that the length direction of the strip-shaped aperture is consistent with the direction of the linear laser emitted by the second line laser, thus guaranteeing that the linear laser is emitted tilted towards the front area of the cleaning robot. The size of the strip-shaped aperture can be designed according to the specific field of view and emission width requirements of the forward sensing device 30. In this embodiment, by using this strip-shaped aperture, the field of view and emission width of the linear laser of the forward sensing device 30 are limited, preventing excessively large field of view or width linear lasers from hitting other structural components and causing stray light interference, thereby affecting the detection and recognition results.
[0060] See Figure 10a In some embodiments, the outer wall of the second mounting bracket 33 is provided with a second light inlet hole 334 that mates with the second limiting hole 332. The second light inlet hole 334 gradually expands from the inside to the outside to ensure that the opening end of the second light inlet hole 334 is large enough to receive the reflected light signals from each part of the linear laser emitted by the second line laser 31. Understandably, the opening size of the second light-attracting aperture 334 gradually increases along the direction away from the light-attracting point. Since the second light-attracting aperture 334 is used to receive reflected light signals, the larger the opening end is, the more reflected light signals the second light-attracting aperture 334 can receive. It should be noted that the opening size of the second light-attracting aperture 334 can be limited according to the opening shape of the second light-attracting aperture 334, and this disclosure does not impose specific limitations on it. For example, if the opening of the second light-attracting aperture 334 is circular, its opening size can be limited by the diameter of the circular opening. Or, for example, if the opening of the second light-attracting aperture 334 is rectangular, its opening size can be limited by the longest side of the rectangle. In other embodiments, the opening shape of the second light-attracting aperture 334 can also be other shapes.
[0061] See Figure 8 and Figure 10aIn some embodiments, the forward sensing device 30 further includes a second circuit board 34, which is mounted on the inner wall of the second mounting bracket 33. The second circuit board 34 is electrically connected to the second line laser 31 and the second camera module 32. The mounting of the second circuit board 34 on the inner wall of the second mounting bracket 33 maintains a relatively fixed position between the second circuit board 34, the second line laser 31, and the second camera module 32, and facilitates the electrical connection between the second line laser 31, the second camera module 32, and the second circuit board 34. The second line laser 31 and the second camera module 32 can be electrically connected to the second circuit board 34 via wires, ribbon cables, or a flexible PCB. Furthermore, the second circuit board 34 can be provided with notches to allow for the second line laser 31 and the second camera module 32 to pass through, ensuring that the installation of the second circuit board 34 does not interfere with the installation of the second line laser 31 and the second camera module 32, allowing for a more compact overall structure of the forward sensing device 30.
[0062] See Figure 10 and Figure 10a In some embodiments, the forward sensing device 30 further includes a second lens 35, which is disposed on the outer wall of the second mounting bracket 33 and covers the second light-emitting hole 333 and the second camera module 32. By setting the second lens 35 to cover the second light-emitting hole 333 and the second camera module 32, damage to the second laser 31 and the second camera module 32 by external objects is avoided. At the same time, dust or dirt is prevented from falling onto the emitting end of the second laser 31 and the receiving end of the second camera module 32, thus protecting the second laser 31 and the second camera module 32 and making the robot casing more concise and aesthetically pleasing.
[0063] See Figure 10a In some embodiments, a second groove 335 is provided on the outer wall of the second mounting bracket 33, and the second lens 35 is adapted to be accommodated in the second groove 335. By providing the second groove 335, the installation and fixation of the second lens 35 are facilitated, and the second lens 35 is also prevented from protruding outward, thus protecting the second lens 35 and making the appearance of the robot shell relatively flat, simpler, and more aesthetically pleasing.
[0064] See Figures 7-9 ,as well as Figure 10a In some embodiments, the forward sensing device 30 further includes a supplementary lighting module 36. A supplementary lighting through-hole 336 is provided on the second mounting bracket 33, and the supplementary lighting module 36 is disposed on the inner wall of the second mounting bracket 33, directly opposite the supplementary lighting through-hole 336. The supplementary lighting module 36 is, for example, a supplementary light lamp, used to provide light enhancement in relatively dim environments to improve the detection and recognition effect of the forward sensing device 30 in dim environments. The supplementary lighting module 36 can also be covered by the second lens 35 to protect it.
