[0068] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.
[0069] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.
[0070] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion meaning and that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first” and “second” are used only as markers and are not a limitation on the number of objects.
[0071] As shown in Figures 1 to 8, this disclosure first provides a laser ranging component 1, which can be applied to cleaning equipment 01 such as a robot vacuum cleaner, floor scrubber, vacuum cleaner, and sweeping and mopping machine for ranging and obstacle detection.
[0072] In some embodiments, the laser ranging component 1 may include a laser ranging module 12. The laser ranging module 12 can emit detection light and receive detection light reflected back from external objects to determine the obstacle situation in the external environment and the distance between itself and the obstacle.
[0073] The laser ranging module 12 can be a lidar to improve its detection accuracy, thereby enhancing the obstacle avoidance capability of the cleaning equipment 01 using the laser ranging module 12. However, it is not limited to this; the laser ranging module 12 can also be any other ranging module capable of emitting detection light.
[0074] As shown in Figure 2, the laser ranging module 12 may include a main body 121 and a detector 122. The main body 121 can be used to connect or install the laser ranging module 12 with other structural components. The detector 122 can be connected to the main body 121 for emitting and receiving detection light. The detector 122 may include a transmitting unit and a receiving unit. The transmitting unit can be used to emit detection light, and the receiving unit can be used to receive detection light reflected back from obstacles in the external environment.
[0075] As shown in Figures 2 and 3, the laser ranging module 12 can rotate around the first direction X to increase its detection range and further improve the obstacle avoidance capability of the cleaning device 01 using this laser ranging module 1. When the laser ranging module 12 rotates around the first direction X, its optical axis can rotate around the first direction X. The path swept by the optical axis during rotation can form a plane, which can be a first reference plane 123. The first reference plane 123 can be perpendicular to the first direction X, or it can be non-perpendicular to the first direction X.
[0076] In some embodiments, the detection unit 122 can rotate independently around a first direction X. That is, when the laser ranging module 12 needs to change its detection orientation, the main body 121 can remain stationary, while the detection unit 122 can rotate relative to the main body 121. This configuration improves the flexibility of the laser ranging module 12's rotation, allowing it to rotate easily even as the cleaning device 01 moves. Furthermore, when the main body 121 remains stationary and only the detection unit 122 rotates, the inertia generated by the laser ranging module 12 during rotation can be reduced. This reduces the impact of the inertia on the normal movement and obstacle crossing of the cleaning device 01, ensuring precise positioning of the cleaning device 01 even as the laser ranging module 12 rotates.
[0077] In this embodiment, the main body 121 may include at least a drive motor, and the detection part 122 may be connected to the rotor of the drive motor so that the drive motor can drive the detection part 122 to rotate.
[0078] In other embodiments, the detection unit 122 can rotate independently around a first direction X. That is, the detection unit 122 can be rotatably connected to the main body 121. When the laser ranging module 12 needs to change its detection orientation, the main body 121 can remain stationary, while the detection unit 122 can rotate relative to the main body 121. This configuration improves the flexibility of the laser ranging module 12's rotation, allowing it to rotate easily during the movement of the cleaning device 01. Furthermore, when the main body 121 remains stationary and only the detection unit 122 rotates, the inertia generated by the laser ranging module 12 during rotation can be reduced. This reduces the impact of the inertia generated during rotation on the normal movement and obstacle crossing of the cleaning device 01, ensuring that the cleaning device 01 can achieve precise positioning even during the rotation of the laser ranging module 12.
[0079] In some embodiments, as shown in Figures 3 to 8, the laser ranging assembly 1 may further include a protective housing 11. The protective housing 11 may have a cavity 111 with a light-transmitting opening 112. The laser ranging module 12 can be disposed within this cavity 111, thus protecting it from damage when the laser ranging assembly 1 is subjected to external forces, thereby improving the service life and reliability of the laser ranging assembly 1. Simultaneously, the detection light emitted by the laser ranging module 12 can exit through the light-transmitting opening 112, ensuring the normal detection operation of the laser ranging module 12 and preventing the protective housing 11 from affecting its detection operation.
[0080] The laser ranging component 1 may further include a light-transmitting element 13. The aforementioned laser ranging module 12 can rotate relative to the light-transmitting element 13. The light-transmitting element 13 can be connected to the protective shell 11 to seal the light-transmitting opening 112. Thus, the light-transmitting element 13 can be used to make the cavity 111 a sealed chamber, preventing dust, hair, liquids and other impurities from the external environment from entering the cavity 111. This also avoids contamination of the laser ranging module 12 by dust, hair, liquids and other impurities, thereby further improving the service life and reliability of the laser ranging module 12, and further improving the service life and reliability of the laser ranging component 1.
[0081] Meanwhile, the light-transmitting element 13 can transmit the detection signal emitted by the laser ranging module 12, thereby avoiding the light-transmitting element 13 from blocking the detection light emitted by the laser ranging module 12, thus further ensuring the normal detection operation of the laser ranging module 12.
[0082] In some embodiments, as shown in Figures 3 to 8, the light-transmitting element 13 may include a light-transmitting plate 131 and at least one connecting plate 132. The light-transmitting plate 131 may be disposed opposite to the light-transmitting opening 112 for transmitting the detection light emitted by the laser ranging module 12. At least one connecting plate 132 may be connected to the light-transmitting plate 131, and the connecting plate 132 may extend at least partially to and be connected to the protective shell 11 to realize the connection between the light-transmitting element 13 and the protective shell 11. By providing the connecting plate 132 and having the connecting plate 132 extend at least partially to the protective shell 11, the connection area of the light-transmitting element 13 can be increased, facilitating the connection between the light-transmitting element 13 and the protective shell 11 and improving the connection stability between the light-transmitting element 13 and the protective shell 11. Simultaneously, this arrangement also improves the structural strength of the light-transmitting plate 131, thereby enhancing its impact resistance and reducing the probability of deformation. This ensures that the light-transmitting plate 131 maintains its original shape, improving the reliability and manufacturability of the laser ranging component 1. Furthermore, this arrangement enhances the sealing effect of the light-transmitting element 13 on the light-transmitting opening 112, further reducing the probability of dust, hair, liquids, and other impurities from the external environment entering the cavity 111, further improving the service life and reliability of the laser ranging component 1.
[0083] The light-transmitting element 13 may include a first connecting plate 1321 and a second connecting plate 1322. The first connecting plate 1321 may be connected to a first side of the light-transmitting plate 131, and the second connecting plate 1322 may be connected to a second side of the light-transmitting plate 131, so as to increase the number of connection points and the connection area between the light-transmitting element 13 and the protective shell 11, and further improve the connection stability between the light-transmitting element 13 and the protective shell 11.
[0084] The protective shell 11 can be at least partially located between the first connecting plate 1321 and the second connecting plate 1322, thereby preventing the first connecting plate 1321 and the second connecting plate 1322 from extending into the cavity 111 and thus avoiding any impact on the emission of the detection light. Simultaneously, this arrangement further improves the structural strength of the light-transmitting element 13 and the sealing effect on the light-transmitting opening 112.
[0085] Furthermore, the first side and the second side can be located at both ends of the light-transmitting plate along the width direction Z, that is, the first connecting plate 1321 and the second connecting plate 1322 can be connected to both ends of the light-transmitting plate 131 along the width direction Z. This arrangement allows both the first connecting plate 1321 and the second connecting plate 1322 to extend along the length direction of the light-transmitting plate 131, thereby increasing the length and connection area of the first connecting plate 1321 and the second connecting plate 1322, further improving the connection stability between the light-transmitting element 13 and the protective shell 11, and further improving the structural strength of the light-transmitting element 13 and the sealing effect on the light-transmitting opening 112.
[0086] However, it is not limited to this. The first side and the second side can also be located at both ends of the light-transmitting plate along the length direction. That is, the first connecting plate 1321 and the second connecting plate 1322 can also be connected to both ends of the light-transmitting plate 131 along the length direction. They can be selected and set according to actual needs, which is also within the protection scope of this disclosure.
[0087] In some embodiments, the light-transmitting element 13 can be an integrated structure, that is, the light-transmitting plate 131 and the connecting plate 132 can be directly formed into a single unit through an integrated process, without having to manufacture the light-transmitting plate 131 and the connecting plate 132 separately and then connect them by riveting, bonding or other connection methods to form the light-transmitting element 13. This configuration can reduce the number of connection points between the light-transmitting plate 131 and the connecting plate 132, thereby increasing the connection strength between the light-transmitting plate 131 and the connecting plate 132, and thus improving the structural strength of the light-transmitting element 13.
[0088] However, it is not limited to this. The light-transmitting element 13 can also be a split structure, that is, the light-transmitting plate 131 and the connecting plate 132 can be manufactured separately, and then connected by riveting, bonding or other connection methods to form the light-transmitting element 13. This setting can reduce the manufacturing difficulty of the light-transmitting element 13.
[0089] In some embodiments, the outer surface of the light-transmitting plate 131 may be provided with at least one reinforcing protrusion 133, and the outer surface of the light-transmitting plate 131 may be the side of the light-transmitting plate 131 facing away from the laser ranging module 12. This arrangement allows the reinforcing protrusion 133 to act as a reinforcing rib of the light-transmitting plate 131, further improving the structural strength of the light-transmitting plate 131, further reducing the probability of deformation of the light-transmitting plate 131, and improving the manufacturability of the light-transmitting component 13. Simultaneously, since the reinforcing protrusion 133 protrudes from the light-transmitting plate 131, it can protect the light-transmitting plate 131, ensuring that when the light-transmitting component 13 collides with an obstacle, it preferentially collides with the reinforcing protrusion 133 instead of colliding with the light-transmitting plate 131, thereby reducing the probability of damage to the light-transmitting plate 131. This ensures that the light-transmitting plate 131 can always transmit detection light normally, guaranteeing the normal detection operation of the laser ranging module 12 and improving the service life and reliability of the laser ranging component 1.
[0090] Furthermore, the light-transmitting plate 131 may include a light-transmitting area 1311 and a peripheral area 1312, with the peripheral area 1312 at least partially surrounding the light-transmitting area 1311. A reinforcing protrusion 133 may be located in the peripheral area 1312 to prevent the reinforcing protrusion 133 from obstructing the light-transmitting area 1311, thereby preventing the reinforcing protrusion 133 from affecting the normal emission of the detection light and ensuring the normal detection operation of the laser ranging module 12.
[0091] In some embodiments, the reinforcing protrusion 133 may extend along the length of the light-transmitting member 13, thereby increasing the protection range of the reinforcing protrusion 133 and further reducing the probability of damage to the light-transmitting plate 131.
[0092] The reinforcing protrusion 133 may also have multiple protrusions to further improve its protective effect on the light-transmitting plate 131, but it is not limited to this. The outer surface of the light-transmitting plate 131 may also have only one reinforcing protrusion.
[0093] The first connecting plate 1321 and the second connecting plate 1322 can be connected to a portion of the light-transmitting plate 131 located in the outer perimeter area 1312. In this case, the reinforcing protrusion 133 can be located at the corresponding position of the first connecting plate 1321 and / or the second connecting plate 1322. However, this is not a limitation; the reinforcing protrusion 133 may not be configured to correspond to the first connecting plate 1321 and / or the second connecting plate 1322. It can be selected and configured according to actual needs.
[0094] It should be noted that this disclosure does not impose specific restrictions on the protrusion size of the reinforcing protrusion 133, which can be selected and set according to the actual situation.
[0095] As shown in Figures 3 and 4, the light-transmitting plate 131 and the first reference plane 123 can have a non-perpendicular first included angle α. This first included angle α can be the angle between the first reference line on the light-transmitting plate 131 and the first reference plane 123. The first reference line is the intersection line of the inner surface of the light-transmitting plate 131 and the second reference plane, and the second reference plane is parallel to the first direction X. That is, it can be understood that the light-transmitting plate 131 is inclined. This setting can avoid or reduce the detection light reflected by the light-transmitting plate 131 from returning to the laser ranging module 12, and thus avoid or reduce the interference of the reflected detection light on the laser ranging module 12, thereby improving the detection accuracy of the laser ranging module 12, improving the obstacle detection performance of the cleaning equipment 01, and thus significantly improving the performance of the cleaning equipment 01.
[0096] The first included angle α can be greater than or equal to 75° and less than or equal to 89°. For example, the first included angle α can be 75°, 76°, 77°, 78°, 79°, 80°, 81°, 82°, 83°, 84°, 85°, 86°, 87°, 88°, 88.5°, 89°, etc. This setting ensures that the light-transmitting plate 131 has a sufficient tilt angle to avoid or reduce the return of the detection light reflected by the light-transmitting plate 131 into the laser ranging module 12. At the same time, this setting can also avoid the problem of the light-transmitting plate 131's height being reduced due to an excessively large tilt angle, thus ensuring that the detection light has a sufficiently large emission range, thereby ensuring the detection range of the laser ranging module 12 and guaranteeing the detection accuracy and performance of the laser ranging component 1.
[0097] In some embodiments, when the first side and the second side are located at the two ends of the light-transmitting plate 131 along the width direction Z, in the emission direction Y of the detection light, the first side of the light-transmitting plate 131 can be closer to the laser ranging module 12 relative to the second side of the light-transmitting plate 131, that is: the light-transmitting plate 131 can be tilted from the first side to the second side in a direction away from the laser ranging module 12.
[0098] In other embodiments, when the first side and the second side are located at the two ends of the light-transmitting plate 131 along the width direction Z, in the emission direction Y of the detection light, the second side of the light-transmitting plate 131 can be closer to the laser ranging module 12 relative to the first side of the light-transmitting plate 131, that is: the light-transmitting plate 131 can be tilted from the first side to the second side toward the direction of being closer to the laser ranging module 12.
[0099] In some embodiments, as shown in Figures 3 to 8, the protective shell 11 may include a positioning structure 113. The positioning structure 113 may be positioned and cooperated with the first connecting plate 1321 and / or the second connecting plate 1322 to position the first connecting plate 1321 and the second connecting plate 1322 when they are connected to the protective shell 11, so as to ensure the positional accuracy of the first connecting plate 1321 and the second connecting plate 1322 and the connection effect between the first connecting plate 1321 and the second connecting plate 1322 and the protective shell 11.
[0100] The protective shell 11 may have a first protective plate 114 and a second protective plate 115 disposed opposite to each other, both of which may be perpendicular to the first direction X. A light-transmitting opening 112 of the protective shell 11 may be located between the first protective plate 114 and the second protective plate 115. A first connecting plate 1321 may at least partially extend to and be connected to the first protective plate 114. A second connecting plate 1322 may at least partially extend to and be connected to the second protective plate 115.
[0101] In some embodiments, the acute angle formed between the first protective plate 114 and the light-transmitting plate 131 can be from 75° to 89°, for example: 75°, 76°, 77°, 78°, 79°, 80°, 81°, 82°, 83°, 84°, 85°, 86°, 87°, 88°, 88.5°, 89°, etc. The acute angle formed between the second protective plate 115 and the light-transmitting plate 131 can also be from 75° to 89°, for example: 75°, 76°, 77°, 78°, 79°, 80°, 81°, 82°, 83°, 84°, 85°, 86°, 87°, 88°, 88.5°, 89°, etc. This arrangement ensures that the light-transmitting plate 131 has a sufficient tilt angle to avoid or reduce the return of the detection light reflected from the light-transmitting plate 131 to the laser ranging module 12.
[0102] The positioning structure 113 may include a first positioning structure 1131 and a second positioning structure 1132. The first positioning structure 1131 may be disposed on the first protective plate 114 and may engage with the first connecting plate 1321. The second positioning structure 1132 may be disposed on the second protective plate 115 and may engage with the second connecting plate 1322. By providing the first positioning structure 1131 and the second positioning structure 1132, the first connecting plate 1321 and the second connecting plate 1322 can be positioned respectively, improving the positioning accuracy of the positioning structure 113 on the first connecting plate 1321 and the second connecting plate 1322, and further ensuring the connection effect between the first connecting plate 1321 and the second connecting plate 1322 and the protective shell 11.
[0103] In some embodiments, the first positioning structure 1131 can be a first stop rib. Both the first stop rib and the first connecting plate 1321 can be located on the side of the first protective plate 114 away from the second protective plate 115. The first stop rib can stop the edge of the first connecting plate 1321 to achieve positioning and cooperation with the first connecting plate 1321.
[0104] Alternatively, the first positioning structure 1131 can be a first positioning groove, which can be located on the side of the first protective plate 114 near the light-transmitting plate 131 and / or on the side of the first protective plate 114 away from the second protective plate 115. At least part of the first connecting plate 1321 can be located in the first positioning groove to achieve positioning and cooperation between the first connecting plate 1321 and the first positioning structure 1131.
[0105] In some embodiments, the second positioning structure 1132 can be a second stop rib. Both the second stop rib and the second connecting plate 1322 can be located on the side of the second protective plate 115 away from the first protective plate 114, and the second stop rib can stop the edge of the second connecting plate 1322 to achieve positioning and cooperation with the second connecting plate 1322.
[0106] Alternatively, the second positioning structure 1132 can be a second positioning groove, which can be located on the side of the second protective plate 115 near the light-transmitting plate 131 and / or on the side of the second protective plate 115 away from the first protective plate 114. At least part of the second connecting plate 1322 can be located in the second positioning groove to achieve positioning and cooperation between the second connecting plate 1322 and the second positioning structure 1132.
[0107] As shown in Figure 3, the protective shell 11 may further include a reinforcing member 116. The reinforcing member 116 may be a reinforcing rib, but is not limited to this. The reinforcing member 116 may be at least disposed on the side of the first protective plate 114 facing the second protective plate 115, and / or, the reinforcing member 116 may be at least disposed on the side of the second protective plate 115 facing the first protective plate 114, to improve the structural strength of the protective shell 11 and to absorb the detection light reflected within the cavity 111, preventing the detection light reflected within the cavity 111 from returning to the laser ranging module 12, thereby further preventing the reflected detection light from interfering with the laser ranging module 12 and further improving the detection accuracy of the laser ranging module 12.
[0108] There may be multiple reinforcing members 116, and the multiple reinforcing members 116 may be arranged at intervals to further improve the structural strength of the protective shell 11 and further improve its ability to absorb the probe light reflected inside the cavity 111. This disclosure does not limit the specific number of reinforcing members 116.
[0109] In some embodiments, as shown in Figures 3 and 6, the cavity 111 may include a receiving cavity 1111 and a light-emitting cavity 1112. At least a portion of the laser ranging module 12 may be disposed within the receiving cavity 1111, and the light-transmitting opening 112 may be disposed on the side of the light-emitting cavity 1112 opposite to the receiving cavity 1111. In the longitudinal direction of the light-transmitting element 13, the length of the light-emitting cavity 1112 may be greater than the length of the receiving cavity 1111. This arrangement can increase the emission range of the detection light, allowing the laser ranging module 12 to have a larger detection range, thereby improving the detection capability and performance of the laser ranging assembly 1.
[0110] As shown in Figures 3 and 5 to 8, the protective shell 11 may include a first protective part 117 and a second protective part 118. The first protective part 117 has a receiving cavity 1111, within which the main body 121 and at least a portion of the detection part 122 can be located. This allows the first protective part 117 to provide an installation position for the laser ranging module 12 and to protect the main body 121.
[0111] The second protective part 118 may be provided with a light-emitting cavity 1112. With this arrangement, the light-transmitting opening 112 can be provided only at the position corresponding to the detection part 122, while the light-transmitting opening 112 is not provided at the position corresponding to the main body part 121. This can minimize the width of the light-transmitting element 13 that blocks the light-transmitting opening 112 while ensuring that the detection signal can be emitted normally, thereby reducing the manufacturing cost of the laser ranging component 1.
[0112] Furthermore, the thickness of the first protective part 117 can be greater than the thickness of the second protective part 118. This arrangement improves the protective capability of the first protective part 117, further enhancing the protection of the laser ranging module 12. Moreover, this arrangement minimizes the height space occupied by the second protective part 118, enabling miniaturization of the laser ranging component 1. This improves the utilization rate of the internal space of the cleaning equipment 01, facilitating the placement of other components within the cleaning equipment 01 and further miniaturizing the cleaning equipment 01.
[0113] In some embodiments, the first protective portion 117 may include a protective protrusion 1171 protruding from the second protective portion along the thickness direction, which may be the same as the first direction X. A cover plate 1172 may be provided on the side of the protective protrusion 1171 facing away from the second protective portion 118. With this arrangement, the cover plate 1172 can be used to shield the receiving cavity 1111, reducing the probability of dust, hair, liquid and other impurities entering the receiving cavity 1111 through the side of the protective protrusion 1171 facing away from the second protective portion 118, and further preventing dust, hair, liquid and other impurities from contaminating the laser ranging module 12.
[0114] Furthermore, as shown in Figure 8, an electrical via 1173 can be provided on the cover plate 1172, through which the laser ranging module 12 can be electrically connected to other components.
[0115] In some embodiments, the protective shell 11 may be provided with at least one connecting lug 120 for fixing the laser ranging component on the side opposite to the light-transmitting component 13, so that the connecting lug 120 can be used to connect with the device body 2 of the cleaning device 01, thereby improving the connection strength and connection stability between the laser ranging component 1 and the device body 2.
[0116] In some embodiments, as shown in FIG5, the protective housing 11 may further include an anti-reflection structure 119. The anti-reflection structure 119 may be disposed within the light-emitting cavity 1112, and at least part of the anti-reflection structure 119 is disposed opposite to the light-transmitting element 13 to absorb the detection light reflected by the light-transmitting element 13, thereby preventing the detection light reflected by the light-transmitting element 13 and the detection signal reflected within the light-emitting cavity 1112 from returning to the laser ranging module 12. This further prevents the reflected detection light from interfering with the laser ranging module 12 and further improves the detection accuracy of the laser ranging module 12.
[0117] In some embodiments, the protective shell 11 may further include a third protective plate 124, which may connect to the first protective plate 114 and the second protective plate 115, and together with the first protective plate 114 and the second protective plate 115, form a light-emitting cavity 1112. At least one of the first protective plate 114, the second protective plate 115 and the third protective plate 124 may be provided with an anti-reflection structure 119.
[0118] The anti-reflective structure 119 can be an anti-reflective coating, that is, the anti-reflective coating can be applied to the inner surface of at least one of the first protective plate 114, the second protective plate 115, and the third protective plate 124. However, it is not limited to this, the anti-reflective structure 119 can also be an anti-reflective structural component, such as a reinforcing member, sponge, felt, rough surface, etc., that is, the anti-reflective structural component can be disposed on the inner surface of at least one of the first protective plate 114, the second protective plate 115, and the third protective plate 124.
[0119] Meanwhile, the anti-reflective structure 119 may also include an anti-reflective coating and anti-reflective structural components. For example, the anti-reflective structure 119 may include a sponge and a reinforcing member 116, or the anti-reflective structure 119 may include a sponge and an anti-reflective coating, etc., so that the anti-reflective performance can be improved by constructing the anti-reflective structure 119 with a variety of anti-reflective components.
[0120] In some embodiments, the light-emitting surface of the light-transmitting element 13 can be arc-shaped. This configuration can increase the angle range of the light-transmitting element 13 transmitting the detection light, so that the laser ranging module 12 can have a larger detection range, thereby improving the detection capability and performance of the laser ranging component 1.
[0121] The edge of the protective shell 11 at the light-transmitting opening 112 can also be arc-shaped to cooperate with the arc-shaped light-transmitting element 13. However, it is not limited to this, and the edge of the protective shell 11 at the light-transmitting opening 112 may not be arc-shaped.
[0122] This disclosure also provides a cleaning device 01. The cleaning device 01 can be a robotic vacuum cleaner, floor scrubber, vacuum cleaner, or a combined sweeping and mopping machine. As shown in Figures 1 to 8, the cleaning device 01 can include a laser ranging component 1 and a device body 2. The laser ranging component 1 can be embedded in the device body 2, and the laser ranging component 1 can be the laser ranging component described above.
[0123] It should be noted that the specific structure and beneficial effects of the laser ranging component 1 have been described in detail in the above embodiments. Therefore, in this embodiment, the specific structure and beneficial effects of the laser ranging component 1 will not be described again. Please refer to the specific description in the above embodiments, which are all within the protection scope of this disclosure.
[0124] The cleaning device 01 provided in this disclosure includes the aforementioned laser ranging component 1 and device body 2. The laser ranging component 1 includes a protective shell 11, a laser ranging module 12, and a light-transmitting element 13. The laser ranging module 12 can be disposed within the cavity 111 of the protective shell 11 to protect the laser ranging module 12 from damage caused by external forces, thereby improving the service life and reliability of the laser ranging component 1. The detection light emitted by the laser ranging module 12 can exit through the light-transmitting opening 112 of the protective shell 11, ensuring the normal detection operation of the laser ranging module 12 and preventing the protective shell 11 from affecting its detection operation.
[0125] The light-transmitting element 13 can be connected to the light-transmitting opening 112 to block the light-transmitting opening 112. This allows the cavity 111 to become a sealed chamber, preventing dust, hair, liquids, and other impurities from the external environment from entering the cavity 111. This also avoids contamination of the laser ranging module 12 by dust, hair, liquids, and other impurities, thereby further improving the service life and reliability of the laser ranging module 12 and the cleaning equipment 01.
[0126] Meanwhile, the light-transmitting element 13 can transmit the detection light emitted by the laser ranging module 12, thereby preventing the light-transmitting element 13 from blocking the detection light emitted by the laser ranging module 12, thus further ensuring the normal detection operation of the laser ranging module 12.
[0127] In addition, the laser ranging component 1 is embedded in the main body 2 of the device, which can protect the laser ranging component 1 and reduce the probability of damage caused by external forces.
[0128] In some embodiments, as shown in FIG1, the main body 2 of the device may include a base 21, on which a traveling mechanism 24 may be provided, allowing the cleaning device 01 to move. A cleaning component 25 may also be provided on the base 21, which can be used to clean the surface to be cleaned. The cleaning component 25 may be a roller brush, a side brush, a water outlet, a mopping component, etc.
[0129] The main body 2 of the equipment may also include a support structure 22. The support structure 22 can be mounted on the base 21 to serve as the main load-bearing structure of the main body 2, thereby improving the structural strength of the main body 2. The support structure 22 can be arranged around the edge of the base 21 to increase its load-bearing capacity and further enhance the structural strength of the main body 2. Simultaneously, the support structure 22 can be used as an anti-collision structure for the main body 2 to protect the various components located within the main body 2, reducing the probability of damage to these components.
[0130] The main body 2 of the device may further include a top cover 23. The top cover 23 may be connected to the support structure 22, and an accommodating space is formed between the base 21 and the top cover 23. The laser ranging component 1 may be disposed within the accommodating space so that the laser ranging component 1 is embedded within the main body 2 of the device. At the same time, other components within the main body 2 may also be located within the accommodating space.
[0131] In some embodiments, the support structure 22 and the top cover 23 can be integrally formed, that is, the support structure 22 and the top cover 23 can be formed simultaneously through an integrated manufacturing process, thereby improving the connection strength between the support structure 22 and the top cover 23. Alternatively, the support structure 22 and the base 21 can be integrally formed, that is, the support structure 22 and the base 21 can be formed simultaneously through an integrated manufacturing process, thereby improving the connection strength between the support structure 22 and the base 21.
[0132] In some embodiments, the support structure 22 may include an outer side plate 221, which may be located on the front side of the support structure 22. The front side of the support structure 22 may be the side of the support structure 22 that is closer to the forward direction of the cleaning device 01.
[0133] The outer side plate 221 may be provided with a light-transmitting hole 2211, and the light-transmitting element 31 may be embedded in the outer side plate 221. The light-transmitting hole 2211 can expose at least part of the light-emitting surface of the light-transmitting element 31 to ensure the light transmission capability of the light-transmitting element 31 and prevent the outer side plate 221 from affecting the normal detection operation of the laser ranging component 1, thereby ensuring the obstacle avoidance capability of the cleaning equipment 01.
[0134] In some embodiments, the cleaning device 01 may further include a collision detection element, which is movably connected to the front side of the device body 02. For example, the collision detection element may be movably connected to the side of the outer side plate 211 facing away from the accommodating space. With this configuration, the collision detection element can be used as an anti-collision structure for the cleaning device 01 to protect the device body 02 and reduce the probability of damage to the device body 02 when the cleaning device 01 is subjected to a collision.
[0135] The collision detection component may be provided with a through hole, which can expose at least part of the light-emitting surface of the light-transmitting component 31 to ensure the light transmission capability of the light-transmitting component 31 and prevent the collision detection component from affecting the normal detection operation of the laser ranging component 1, thereby ensuring the obstacle avoidance capability of the cleaning equipment 01.

The cleaning device 01 can be the cleaning device described above, and the cleaning device 01 can interface with the base station. The base station can charge, replenish water, and clean the cleaning device 01, or suck out dirt stored in the cleaning device 01.
[0137] It should be noted that the specific structure and beneficial effects of the cleaning device 01 have been described in detail in the above embodiments. Therefore, in this embodiment, the specific structure and beneficial effects of the cleaning device 01 will not be described again. Please refer to the specific description in the above embodiments, which are all within the protection scope of this disclosure.
