[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining this application and not for limiting this application. It should also be noted that, for ease of description, only the parts related to this application are shown in the accompanying drawings, not all structures. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0040] See Figure 1 , Figure 1 This is a schematic diagram of the structure of a cleaning device in some embodiments of this application. The cleaning device 10 is applied to a cleaning robot and includes a housing 101, a drive assembly 102, and a cleaning assembly 103.
[0041] The drive assembly 102 is disposed on the housing 101. The cleaning assembly 103 is disposed on the housing 101 and is coupled to the drive assembly 102.
[0042] The drive assembly 102 drives the cleaning assembly 103 to move between a first position and a second position. During this movement, the cleaning assembly 103 can perform cleaning functions or avoid obstacles.
[0043] In some embodiments, the first position is close to the housing 101, and the second position is away from the housing 101. When the cleaning component 103 moves to the first position, the cleaning component 103 is close to the housing 101, causing the cleaning component 103 to approach the cleaning robot, thereby enabling the cleaning component 103 to be retracted or to avoid obstacles. When the cleaning component 103 moves to the second position, the cleaning component 103 is away from the housing 101, causing the cleaning component 103 to move away from the cleaning robot, thereby enabling the cleaning component 103 to be extended or to avoid obstacles.
[0044] In other embodiments, the first position is away from the housing 101, and the second position is close to the housing 101. When the cleaning component 103 moves to the first position, it moves away from the housing 101, bringing it closer to the cleaning robot, thus enabling the cleaning component 103 to be extended or to avoid obstacles. When the cleaning component 103 moves to the second position, it moves closer to the housing 101, bringing it closer to the cleaning robot, thus enabling the cleaning component 103 to be retracted or to avoid obstacles.
[0045] It is understood that the determination of the first and second positions is related to the size and shape of the housing 101. The determination of the first and second positions is related to the position of the cleaning component 103 on the housing 101, the size of the cleaning component 103, and its current condition.
[0046] In some embodiments, such as Figure 1 As shown, the housing 101 has a movable space O. The shape and size of the movable space O can be set according to the actual situation, and are not limited here.
[0047] In some embodiments, such as Figure 1 As shown, the housing 101 includes a gearbox 104, which has a rotating part 1041 disposed within the movable space. At this time, the drive assembly 102 is configured to drive the rotating part 1041 to move within the movable space O, causing the gearbox 104 and the cleaning assembly 103 to move between a first position and a second position.
[0048] It is understood that the activity space O can limit the range of motion of the rotating part 1041, thereby displaying the range of motion of the gearbox 104 and the cleaning assembly 103. At this time, the first position and the second position can be the positions of the cleaning assembly 103 when the rotating part 1041 moves to the two ends of the activity space O.
[0049] In some embodiments, such as Figure 1 As shown, the drive assembly 102 includes a first drive assembly 105 and a transmission assembly 106. The first drive assembly 105 is spaced apart from the gearbox 104. One end of the transmission assembly 106 is connected to the first drive assembly 105, and the other end of the transmission assembly 106 is connected to the rotating part 1041. The first drive assembly 105 is used to drive the rotating part 1041 to move within the active space O via the transmission assembly 106.
[0050] In some embodiments, such as Figure 1 As shown, the cleaning device 10 also includes an elastic element 107. One end of the elastic element 107 is connected to the housing 101, and the other end of the elastic element 107 is connected to the gearbox 104. The gearbox 104 and the cleaning assembly 103 move closer to the housing 101 under the drive of the transmission assembly 106 and the elastic element 107, causing the cleaning assembly 103 to move between a first position and a second position.
[0051] For example, when the first drive assembly 105 is energized, the first drive assembly 105 rotates counterclockwise, and the first drive assembly 105 drives the transmission assembly 106 to rotate counterclockwise within the active space O. At this time, the transmission assembly 106 drives the rotating part 1041 of the gearbox 104 to "disengage" from the transmission assembly 106, and the gearbox 104 rotates counterclockwise and swings out under the action of the elastic member 107.
[0052] For example, when the first drive assembly 105 is energized, the first drive assembly 105 rotates clockwise, and the first drive assembly 105 drives the transmission assembly 106 to rotate clockwise within the active space O. At this time, the transmission assembly 106 drives the rotating part 1041 of the gearbox 104 to rotate clockwise and retract against the force of the elastic member 107.
[0053] For example, when the first drive assembly 105 is energized, the first drive assembly 105 rotates clockwise, and the first drive assembly 105 drives the transmission assembly 106 to rotate clockwise within the active space O. At this time, the transmission assembly 106 drives the rotating part 1041 of the gearbox 104 to "disengage" from the transmission assembly 105, and the gearbox 104 rotates clockwise and swings out under the action of the elastic member 107.
[0054] For example, when the first drive assembly 105 is energized, the first drive assembly 105 rotates counterclockwise, and the first drive assembly 105 drives the transmission assembly 106 to rotate counterclockwise within the active space O. At this time, the transmission assembly 106 drives the rotating part 1041 of the gearbox 104 to rotate counterclockwise and retract against the force of the elastic member 107.
[0055] In some embodiments, the first drive component 105 is a motor or other driver. For example, a servo motor or a DC motor.
[0056] In some embodiments, the angle between the first position and the second position is not 360 degrees, but ranges from (0 to 360), such as 30 degrees, 60 degrees, 90 degrees, 120 degrees, or others. In this case, the gearbox 104 and the cleaning assembly 103 can move in a circular motion about the housing 101 as the center or rotation axis, moving closer to or further away from the housing 101. The angle of motion of the gearbox 104 and the cleaning assembly 103 is related to the size and shape of the housing 101, and can be determined according to actual conditions.
[0057] In some embodiments, the elastic element 107 may be a spring, silicone, or other materials. For example, the elastic element 107 is a torsion spring.
[0058] The connection position of the elastic element 107 with the housing 101 and the gearbox 104 can be determined according to the actual situation. For example, one end of the elastic element 107 is connected to the side of the housing 101, and the other end of the elastic element 107 is connected to the cover of the gearbox 104.
[0059] See Figure 2 , Figure 2 This is a schematic diagram of the cleaning device in some embodiments of this application. The transmission assembly 106 includes a pull rod 1061 and a connecting rod 1062. One end of the pull rod 1061 is connected to the rotating part 1041, and the other end of the pull rod 1061 is connected to one end of the connecting rod 1062. The other end of the connecting rod 1062 is connected to the first drive assembly 105.
[0060] The first drive assembly 105 is used to drive the rotating part 1041 to move within the active space O via the pull rod 1061 and the connecting rod 1062.
[0061] In some embodiments, such as Figure 3 As shown, the rotating part 1041 of the gearbox 104 includes a protrusion 201, one end of which is connected to one end of the pull rod 1061, and the protrusion 201 is located in the movable space O.
[0062] In some embodiments, such as Figure 3 As shown, the end of the connecting rod 1062 connected to the first drive assembly 105 is provided with a groove 202, and the end of the connecting rod 1062 connected to the pull rod 1061 is provided with a through hole 203. The end of the pull rod 1061 connected to the connecting rod 1062 is provided with a protrusion 204, and the end of the pull rod 1061 connected to the protrusion 201 is provided with a sliding groove 205.
[0063] The drive shaft of the first drive assembly 105 is disposed within the groove 202. The protrusion 204 is disposed within the through hole 203. The slide groove 205 is connected to the protrusion 201 on one side, that is, the slide groove 205 is connected to a portion of the protrusion 201.
[0064] In some embodiments, the groove 205 partially surrounds the protrusion 201.
[0065] It is understood that the size and shape of the groove 202 correspond to the size and shape of the drive shaft of the first drive assembly 105. The size and shape of the protrusion 204 correspond to the size and shape of the through hole 203. The size and shape of the groove 205 correspond to the size and shape of the protrusion 201.
[0066] In some embodiments, the protrusion 204 and the groove 205 on the pull rod 1061 are disposed on different sides. Specifically, the pull rod 1061 includes a rod body, a protrusion 204 and a groove 205, which are disposed on different sides of the rod body.
[0067] For example, such as Figure 3 As shown, the protrusion 204 is disposed on the first side of the rod, and the groove 205 is disposed on the second side of the rod opposite to the first side.
[0068] For example, the protrusion 204 is disposed on the first side of the rod, and the groove 205 is disposed on the second side of the rod adjacent to the first side.
[0069] In some embodiments, the first drive assembly 105 is used to drive the protrusion 201 to move within the active space O via the pull rod 1061 and the connecting rod 1062. The gearbox 104 and the cleaning assembly 103 move closer to or away from the housing 101 under the drive of the pull rod 1061, the connecting rod 1062 and the elastic member 107, so that the cleaning assembly 103 moves closer to or away from the cleaning robot.
[0070] For example, when the first drive assembly 105 is energized, the first drive assembly 105 rotates counterclockwise, and the first drive assembly 105 drives the connecting rod 1062 to rotate. The connecting rod 1062 drives the pull rod 1061 to rotate counterclockwise within the active space O. At this time, the protrusion 201 of the gearbox 104 "disengages" from the pull rod 1061, and the gearbox 104 rotates counterclockwise and swings out under the action of the elastic member 107.
[0071] For example, when the first drive assembly 105 is energized, the first drive assembly 105 rotates clockwise, and the first drive assembly 105 drives the connecting rod 1062 to rotate. The connecting rod 1062 drives the pull rod 1061 to rotate clockwise within the active space O. At this time, the pull rod 1061 drives the protrusion 201 of the gearbox 104 to rotate clockwise and retract against the force of the elastic member 107.
[0072] For example, when the first drive assembly 105 is energized, the first drive assembly 105 rotates clockwise, and the first drive assembly 105 drives the connecting rod 1062 to rotate. The connecting rod 1062 drives the pull rod 1061 to rotate clockwise within the active space O. At this time, the protrusion 201 of the gearbox 104 "disengages" from the pull rod 1061, and the gearbox 104 rotates clockwise and swings out under the action of the elastic member 107.
[0073] For example, when the first drive assembly 105 is energized, the first drive assembly 105 rotates counterclockwise, and the first drive assembly 105 drives the connecting rod 1062 to rotate. The connecting rod 1062 drives the pull rod 1061 to rotate counterclockwise within the active space O. At this time, the pull rod 1061 drives the protrusion 201 of the gearbox 104 to rotate counterclockwise and retract against the force of the elastic member 107.
[0074] See Figure 4 , Figure 4 This is a schematic diagram of the structure of a cleaning device in some embodiments of this application. The cleaning device 10 includes a housing 101, a cleaning component 103, a gearbox 104, a first drive component 105, a transmission component 106, an elastic element 107, a second drive component 108, and a detection component 109.
[0075] The second drive component 108 is disposed within the housing 101, and the active space O is disposed around the second drive component 107.
[0076] The detection component 109 is disposed within the gearbox 104 or within the housing 101, and the second drive component 108 is used to stop working when the detection component 109 generates a detection signal.
[0077] In some embodiments, the second drive component 108 is a motor or other driver. For example, a servo motor or a DC motor.
[0078] The second drive component 108 may be of the same type or different from the first drive component 105, which is not limited here.
[0079] In some embodiments, when the cleaning component 103 rotates to its highest point above the ground, the detection component 109 generates a detection signal and transmits the detection signal to the second drive component 108. The second drive component 108 stops working under the control of the detection signal, so that the cleaning component 103 is suspended at its highest point above the ground, thereby raising the cleaning component 103.
[0080] In some embodiments, such as Figure 5 As shown, the cleaning assembly 103 includes a side brush head 1031 and at least one side brush 1032. One end of the side brush head 1031 is connected to the gearbox 104, and the other end is connected to the side brush 1032. The side brush head 1031 rotates under the drive of the second drive assembly 108 and the gearbox 104, while the side brush 1032 moves between a first position and a second position under the drive of the side brush head 1031, thus moving closer to or further away from the cleaning robot.
[0081] The number of side brushes 1032 in the cleaning component 103 can be set according to actual needs. For example, the number of side brushes 1032 in the cleaning component 103 can be 1, 2, 3, 4 or other numbers.
[0082] When multiple side brushes 1032 are present, they are arranged around the side brush working head 1031. Different cleaning ranges can be achieved through reasonable arrangement. The cleaning range of the multiple side brushes 1032 on the side brush working head 1031 includes at least 30° cleaning, 90° cleaning, 120° cleaning, 180° cleaning, or 360° cleaning.
[0083] The cleaning range of the cleaning component 103 is related to the number of side brushes 1032 and the position of the side brushes 1032 on the side brush working head 1031. For example, the cleaning component 103 includes two side brushes 1032. When these two side brushes 1032 are set on the side brush working head 1031, the angle between them can be 30°, 60° or other angles, and different angles correspond to different cleaning ranges.
[0084] It is understandable that multiple side brushes 1032 can be arranged in a circle with the side brush working head 1031 as the center.
[0085] In some embodiments, a plurality of side brushes 1032 are disposed on one side of the side brush working head 1031. For example... Figure 5 As shown, three side brushes 1032 are set on one side of the side brush working head 1031, and the cleaning range of the three side brushes 1032 is 120°.
[0086] In some embodiments, such as Figure 5 As shown, each side brush 1032 includes a rubber-coated portion 301 and a bristle portion 302. One end of the rubber-coated portion 301 is connected to the side brush working head 1031, and the other end of the rubber-coated portion 301 is connected to the bristle portion 302. The bristle portion 302 is provided with bristles.
[0087] The bristles of the brush portion 302 are used to sweep up hair and other small items. The rubber-coated portion 301 cannot sweep up small items such as dust, but it can sweep up some larger items such as garbage bags and hair. When the side brush 1032 rotates, hair and other small items can be detached from the bristle portion 302 or the rubber-coated portion 301 under the action of centrifugal force.
[0088] In some embodiments, the bristle portion 302 includes a rod, and the bristles may be disposed on one side or all of the rod.
[0089] See Figure 6 and Figure 7 , Figure 6 and Figure 7 This is a schematic diagram of the gearbox structure in some embodiments of this application. The gearbox 104 includes a cover 1042 and a gear assembly 1043. The gear assembly 1043 is disposed inside the cover 1042. One end of the gear assembly 1043 is connected to the second drive assembly 108, and the other end of the gear assembly 1043 is connected to the side brush working head 1031.
[0090] The gear assembly 1043 is used to rotate under the drive of the second drive assembly 108, thereby driving the side brush working head 1031 to rotate.
[0091] In some embodiments, the gear assembly 1043 includes at least two gears.
[0092] Exemplarily, the gear assembly 1043 includes a first gear and a second gear. The first gear is kinetically connected to the second gear. The first gear is connected to the second drive assembly 108, specifically, the first gear is connected to the drive shaft of the second drive assembly 108. The second gear is connected to the side brush working head 1031, specifically, the gear post of the second gear is connected to the side brush working head 1031. The first gear rotates under the drive of the second drive assembly 108, the second gear rotates under the drive of the first gear, and the second gear drives the side brush working head 1031 to rotate. The first gear and the second gear are driven by interleaved shafts.
[0093] Exemplarily, the gear assembly 1043 includes a first gear, a second gear, and a third gear. The first gear and the second gear are spaced apart, and the third gear is disposed between the first gear and the second gear, and the third gear is drivingly connected to both the first gear and the second gear. The first gear is connected to the second drive assembly 108, specifically, the first gear is connected to the drive shaft of the second drive assembly 108. The second gear is connected to the side brush working head 1031, specifically, the gear post of the second gear is connected to the side brush working head 1031. Under the drive of the second drive assembly 108, the first gear drives the third gear to rotate, and the second gear drives the side brush working head 1031 to rotate under the drive of the third gear. The first gear and the third gear, and the third gear and the second gear, are driven by interleaved shafts.
[0094] For example, such as Figure 7 As shown, the gear assembly 1043 includes a first gear 401, a second gear 402, a third gear 403, and a fourth gear 404. The first gear 401 and the second gear 402 are spaced apart, the third gear 403 is positioned between the first gear 401 and the second gear 402, and the fourth gear 404 is drive-connected to the first gear 401. The fourth gear 404 is connected to the drive shaft of the second drive assembly 108, specifically, the fourth gear 404 is connected to the drive shaft of the second drive assembly 108. The fourth gear 404 rotates under the drive of the second drive assembly 108, the first gear 401 rotates under the drive of the fourth gear 404, and the first gear 401 drives the third gear 403 to rotate, which in turn drives the second gear 402 to rotate. The second gear 402 is connected to the side brush working head 1031, specifically, the gear post of the second gear 402 is connected to the side brush working head 1031, so that the side brush working head 1031 rotates under the drive of the second gear 402. Among them, the first gear 401 and the third gear 403, the first gear 401 and the fourth gear 404, and the third gear 403 and the second gear 402 are driven by interleaved shafts.
[0095] In other embodiments, the number of gears in the gear assembly 1043 may be 5, 6, 7, or others. The number of gears in the gear assembly 1043 is related to the positional relationship between the second drive assembly 108 and the gearbox 104, as well as the dimensions of the cover 1042 of the gearbox 104.
[0096] In some embodiments, the axial direction of the second gear 402 ( Figure 7 (indicated by "X") and the radial direction of the cover 1042 ( Figure 7 (The two objects intersect, indicated by "Y"), and the included angle is acute.
[0097] In some embodiments, the axial direction of the second gear 402 intersects the radial direction of the cover 1042, and the included angle is an obtuse angle. In this case, the second gear 402 is inclined relative to the cover 1042. When the second gear 402 is connected to the side brush working head 1031, the side brush working head 1031 can also be inclined relative to the cover 1042.
[0098] In some embodiments, the axial direction of the second gear 402 intersects the axial direction of the other gears in the gear assembly 1043, and the included angle is an acute angle or an obtuse angle. In this case, the second gear 402 is inclined relative to the gear assembly 1043.
[0099] Based on this, the second gear 402 is inclined on the cover 1042. The other gears in the gear assembly 1043, except for the second gear 402, are arranged parallel to the cover 1042.
[0100] In some embodiments, the side brush 1032 is inclined relative to the cover 1042. In this case, the side brush 1032 is in contact with the ground in the first position and moves away from the ground in the second position. Alternatively, the side brush 1032 moves away from the ground in the first position and is in contact with the ground in the second position. It is understood that the inclined arrangement of the side brush 1032 allows for the raising and lowering of the side brush 1032 when the side brush 1032 is moved between the first and second positions. This enables cleaning of the ground or the like to begin when the side brush 1032 descends, and cleaning of the ground or the like to end or avoid obstacles or the like to begin when the side brush 1032 rises.
[0101] In some embodiments, such as Figure 8 As shown, the side brush working head 1031 includes a T-slot.
[0102] When the gear assembly 1043 includes two gears, or the gear assembly 1043 includes three gears, or the gear assembly 1043 includes four gears, or even other numbers of gears, the gear post of the second gear 402 is disposed in the T-slot.
[0103] Because the second gear 402 is tilted, both the side brush head 1031 and the side brush 1032 connected to the second gear 402 are tilted. As a result, the axial direction of the side brush head 1031 intersects the radial direction of the cover 1042, and the included angle is an obtuse angle or an acute angle.
[0104] Since the positional relationship between the side brush 1032 and the side brush working head 1031 can be set according to the actual situation, the extension direction of the side brush 1032 is ( Figure 8 The angle between the gear (indicated by "Z") and the axial direction of the second gear 402 is acute, right or obtuse.
[0105] In some embodiments, the side brush 1032 is tilted relative to the ground, forming an angle with the ground. When the bristle portion 302 of the side brush 1032 rotates to one side, it lifts off the ground, achieving a lifting function. The lifting function can be performed when cleaning the ground is finished or when avoiding obstacles. When the bristle portion 302 of the side brush 1032 rotates to the other side, it touches the ground, achieving a lowering function. The lowering function can be performed when cleaning the ground is started or when avoiding obstacles is finished.
[0106] In some embodiments, when the side brush 1032 rotates to its highest point above the ground, the detection component 109 generates a detection signal and transmits the detection signal to the second drive component 108. The second drive component 108 stops working under the control of the detection signal, so that the side brush 1032 is suspended at its highest point above the ground, thereby raising the side brush 1032.
[0107] In some embodiments, such as Figure 9 As shown, the gearbox 104 also includes a copper sleeve 1044 and a bumper strip 1045. The copper sleeve 1044 is disposed within the cover 1042, and the gear post of the second gear 402 in the gear assembly 1043 passes through the copper sleeve 1044 and is connected to the side brush working head 1031. The bumper strip 1045 is disposed within the cover 1042 and is used to prevent collisions and scratches between components disposed within the gearbox 104.
[0108] The material of the anti-collision strip 1045 can be rubber, sponge or other materials.
[0109] In some embodiments, such as Figure 7 As shown in Figure 9, the cover 1042 of the gearbox 104 is also provided with several limiting grooves (not shown in the figure). The limiting grooves are used to accommodate the gear shafts of some gears in the gear assembly 1043, and some gears in the gear assembly 1043 can rotate within the limiting grooves.
[0110] In some embodiments, such as Figure 10As shown, the detection component 109 includes a magnet 1091 and a magnetic signal sensor (not shown). The magnet 1091 is disposed on the second gear 402. The magnetic signal sensor is disposed on the cover 1042.
[0111] Among them, the magnetic signal sensor is used to sense the magnet 1091 to generate a detection signal.
[0112] The specific location of the magnetic signal sensor on the cover 1042 can be determined according to the actual situation. For example, the magnetic signal sensor can be set on the inner wall of the cover 1042; or it can be set on other parts of the gearbox 104.
[0113] In some embodiments, the magnet 1091 rotates with the second gear 402, while the magnetic signal sensor does not rotate with any gear in the gear assembly 1043. Therefore, the magnetic signal sensor can only sense the magnet 1091 under specific conditions, thereby generating a detection signal.
[0114] Specifically, when the side brush 1032 rotates to its highest point above the ground, the magnet 1091 triggers the magnetic signal sensor, which generates a detection signal and transmits it to the second drive component 108. Under the control of the detection signal, the second drive component 108 stops working, causing the side brush 1032 to hover at its highest point above the ground, thus lifting the side brush 1032.
[0115] See Figure 11 , Figure 11 This is a schematic diagram of the cleaning device in some embodiments of this application. The housing 101 includes an upper housing 1011 and a lower housing 1012, with the upper housing 1011 having a movable space. A second drive assembly 108 is disposed on the upper housing 1011. One side of a gearbox 104 is disposed between the upper housing 1011 and the lower housing 1012, allowing the gearbox 104 to rotate around the drive shaft of the second drive assembly 108.
[0116] The shape and size of the active space O, as well as the position of the active space O on the upper shell 1011, can be set according to the actual situation, and are not restricted here.
[0117] In summary, the cleaning device 10 provided in some embodiments of this application can drive the rotating part 1041 in the gearbox 104 to move using the first drive assembly 105, and then control the movement of the gearbox 104 and the cleaning assembly 103 using the transmission assembly 106 and the elastic member 107. This allows the gearbox 104 and the cleaning assembly 103 to move closer to or further away from the housing 101 under the action of the transmission assembly 106 and the elastic member 107, thereby enabling the gearbox 104 and the cleaning assembly 103 to swing out or retract. Based on this, when the gearbox 104 and the cleaning assembly 103 swing out, the cleaning assembly 103 can be used to clean the corner area. After cleaning is completed, away from the corner area, or when encountering obstacles, the gearbox 104 and the cleaning assembly 103 can be retracted to avoid collisions and damage to the cleaning assembly 103.
[0118] Furthermore, the cleaning device 10 can also use the second drive component 108 and the detection component 109 to achieve the following: when the side brush 1032 in the cleaning component 103 is furthest from the ground, it can be suspended to raise the side brush 1032; and when the side brush 1032 in the cleaning component 103 is lowered to touch the ground, it can be lowered to touch the ground.
[0119] See Figure 12 , Figure 12 This is a schematic diagram of the structure of a cleaning robot in some embodiments of this application. The cleaning robot 100 includes a main body 20 and a cleaning device 10 as described in any of the above embodiments, which will not be repeated here.
[0120] The cleaning device 10 is disposed on the main body 20. Specifically, the cleaning device 10 is disposed on the side of the main body 20 or on the bottom surface of the main body 20.
[0121] The cleaning robot 100 may include at least one cleaning device 10. When the cleaning robot 100 includes multiple cleaning devices 10, the positions of the multiple cleaning devices 10 on the main body 20 can be set according to the actual situation, and there is no limitation here.
[0122] See Figure 13 , Figure 13 This is a schematic diagram of the structure of a cleaning robot in some embodiments of this application. The cleaning robot 100 includes a cleaning device 10, a main body 20 and at least one detection element 30. The cleaning device 10 is disposed on the main body 20.
[0123] At least one detection element 30 is disposed on the main body 20 and / or the cleaning device 10. Specifically, at least one detection element 30 is disposed on the main body 20. At least one detection element 30 is disposed in the cleaning device 10.
[0124] The position of at least one detection element 30 on the main body 20 can be set according to actual conditions and is not limited here. The position of at least one detection element 30 on the cleaning device 10 can be set according to actual conditions and is not limited here.
[0125] At least one detection element 30 is used to detect the positional relationship between the gearbox 104 and the main body 20 in the cleaning device 10. The positional relationship is configured to control the movement state of the first drive assembly 105 in the cleaning device 10 and the movement state of the main body 20.
[0126] At least one detection element 30 is used to detect the positional relationship between the gearbox 104 and the main body 20 in the cleaning device 10, and to control the first drive component 105 in the cleaning device 10 to rotate or stop based on the positional relationship; and to control the main body 20 to move forward or backward based on the positional relationship.
[0127] The cleaning robot 100 provided in some embodiments of this application includes a cleaning device 10 and a main body 20. By mounting the cleaning device 10 on the main body 20, the rotating part 1041 in the gearbox 104 can be moved by the first drive assembly 105. Then, the movement of the gearbox 104 and the cleaning assembly 103 can be controlled by the transmission assembly 106 and the elastic member 107. Under the action of the transmission assembly 106 and the elastic member 107, the gearbox 104 and the cleaning assembly 103 move closer to or further away from the housing 101, realizing the swinging out or retraction of the gearbox 104 and the cleaning assembly 103. Based on this, when the gearbox 104 and the cleaning assembly 103 are swinging out, the cleaning assembly 103 can be used to clean the corner area. When cleaning is completed, away from the corner area, or when encountering obstacles, the gearbox 104 and the cleaning assembly 103 can be retracted to avoid collision and damage to the cleaning assembly 103. Furthermore, the positional relationship between the gearbox 104 and the main body 20 in the cleaning device 10 can be used to control the movement state of the cleaning robot 100 and the movement state of the cleaning device 10.
[0128] In an application scenario, such as Figure 14 As shown, the main body 20 is equipped with three detection elements 30, namely a first detection element, a second detection element, and a third detection element. The first and second detection elements are mounted on the main body 20, and the third detection element is mounted on the cleaning device 10 and connected to the cover 1042 of the gearbox 104 on the cleaning device 10. When the gearbox 104 is detected to be in the first position, the first detection element is triggered, controlling the first drive assembly 105 to stop counterclockwise. When the gearbox 104 is detected to be in the second position, the second detection element is triggered, controlling the first drive assembly 105 to stop clockwise. When the gearbox 104 is detected to be in the third position, the third detection element is triggered, determining that the cleaning robot 100 has collided with an obstacle, and controlling the cleaning robot 100 to move backward as a whole.
[0129] When multiple detection elements 30 are provided on the main body 20, the multiple detection elements 30 may be of the same or different types. The type of detection element 30 can be a magnetic signal sensor, an infrared signal sensor, a pressure sensor, or other sensors, and there is no limitation here.
[0130] When there are multiple positional relationships between the gearbox 104 and the main body 20, the positional relationship can be determined according to the actual situation, and there is no restriction here.
[0131] The cleaning robot 100 provided in some embodiments of this application includes a cleaning device 10, a main body 20, and at least one detection element 30. By mounting the cleaning device 10 on the main body 20, the rotating part 1041 in the gearbox 104 can be moved by the first drive assembly 105. Then, the movement of the gearbox 104 and the cleaning assembly 103 can be controlled by the transmission assembly 106 and the elastic element 107, so that the gearbox 104 and the cleaning assembly 103 move closer to or further away from the housing 101 under the action of the transmission assembly 106 and the elastic element 107, realizing the swinging out or retraction of the gearbox 104 and the cleaning assembly 103. Based on this, when the gearbox 104 and the cleaning assembly 103 are swinging out, the cleaning assembly 103 can be used to clean the corner area. When cleaning is completed, away from the corner area, or when encountering obstacles, the gearbox 104 and the cleaning assembly 103 can be retracted to avoid collision and damage to the cleaning assembly 103. Furthermore, the positional relationship between the gearbox 104 and the main body 20 in the cleaning device 10 can be used to control the cleaning robot 100 to move forward or backward, as well as to control the rotation or stop of the cleaning device 10.
[0132] In summary, the cleaning device 10 and cleaning robot 100 provided in some embodiments of this application can swing out or retract the gearbox 104 and the cleaning assembly 103. They can hover the side brush 1032 in the cleaning assembly 103 when it is furthest from the ground, raising the side brush 1032, and lowering the side brush 1032 in the cleaning assembly 103 to bring it to the ground.
[0133] Furthermore, the detection component 30 installed inside the cleaning robot 100 can perform detection and protection, such as detecting whether to control the second drive component 108 to stop working, or detecting whether to control the cleaning robot 100 to move backward when it encounters an obstacle.
