[0084] In an embodiment, the device body 100 is configured to automatically move along a target direction on a travel surface, which can be a surface to be cleaned by the cleaning device 10. The cleaning device 10 can be a sweeping and mopping robot, and the cleaning device 10 works on the ground, which is the travel surface.
[0085] In an embodiment, the cleaning module is arranged on the device body 100 and performs cleaning operations on the travel surface as the device body 100 travels.

In an embodiment, in order to enable the cleaning device 10 to move more stably on the ground or have stronger movement ability, the cleaning device 10 can further include one or more steering wheels; wherein the steering wheels can be driven wheels or driving wheels, and the structural forms thereof include but are not limited to universal wheels, and the steering wheels can be located in front of the driving wheel assembly. The driving motor provides power for the driving wheel assembly and / or the steering wheels.
[0087] In an embodiment, the sensing module includes a position determining device located above the device body 100, a bumper located at the front portion of the device body 100, a cliff sensor and an ultrasonic sensor located at the bottom of the device body 100, an infrared sensor, a magnetometer, an accelerometer, a gyroscope, an odometer, and the like, which provide various position information and motion state information of the device body 100 to the control module. For example, the position determining device above the device body 100 is provided with a laser sensor, and when the driving wheel assembly propels the cleaning device 10 to walk on the ground during the cleaning process, the laser sensor detects one or more objects in the travel path of the cleaning device 10, and the cleaning device 10 can control the driving structure to respond to the objects, such as climbing over a step, by detecting the objects such as a step, an obstacle, a wall, and the like by the bumper.
[0088] In an embodiment, the control module can comprehensively judge the current working state of the cleaning robot, such as climbing a step, passing a threshold, being on a carpet, being at a cliff, being stuck above or below, being full of dust, being picked up, and the like, by combining the distance information, speed information, and the like, fed back by the bumper, the cliff sensor and the ultrasonic sensor, the infrared sensor, the magnetometer, the accelerometer, the gyroscope, the odometer, and the like, and can give specific next action strategies for different situations, so that the work of the cleaning device 10 is more in line with the requirements of the owner, and better user experience is achieved. Further, the control module can plan the most efficient and reasonable cleaning path and cleaning mode based on the real-time map information drawn by SLAM (Simultaneous Localization and Mapping), and can improve the cleaning efficiency of the cleaning device 10.
[0089] In an embodiment, the cleaning device 10 comprises a cleaning head provided with a mop for mopping cleaning; the base station 20 is provided with a cleaning tank, and the cleaning device 10 can be placed on the cleaning tank of the base station 20 after completing the mopping cleaning, so that the mop on the cleaning head is self-cleaned by the cleaning member in the cleaning tank. In this embodiment, a plurality of cleaning heads can be provided on the cleaning device 10, and each cleaning head can be located in a corresponding cleaning tank, that is, the number of cleaning tanks can be the same as the number of cleaning heads, so that the plurality of cleaning heads can be self-cleaned at the same time.
[0090] In an embodiment, the energy module comprises a rechargeable battery, such as a nickel-hydrogen battery or a lithium battery. The rechargeable battery can be connected with a charging control circuit, a battery pack charging temperature detection circuit and a battery undervoltage monitoring circuit, and the charging control circuit, the battery pack charging temperature detection circuit and the battery undervoltage monitoring circuit are connected with the single-chip microcomputer control circuit. In this embodiment, the device body 100 is connected with the charging pile through the charging electrode arranged on the side or the lower side of the machine body for charging.
[0091] In an embodiment, the man-machine interaction module comprises a button on the panel of the device body 100, which is used for function selection by the user; and can further comprise a display screen and / or an indicator light and / or a loudspeaker, which displays the current state of the machine or the function selection item to the user; and can further comprise a mobile phone client program. For the path navigation type cleaning device 10, the mobile phone client can display a map of the environment where the device is located and the position of the machine to the user, and can provide more abundant and humanized function items to the user.
[0092] As shown in Figures 2 to 4 When the cleaning device 10 is in a non-working state, the laser sensor above the device body 100 can be withdrawn into the device body 100 under the driving of the driving assembly, so as to hide the collision detection module 30, thereby avoiding the influence of sewage, oil stains, dust and other sundries on the performance and service life of the laser sensor. When the cleaning device 10 is in a working state, the laser sensor above the device body 100 can be extended above the device body 100 under the driving of the driving assembly, so as to detect one or more objects in the driving path of the cleaning device 10. However, since the laser sensor is at a high position when the cleaning device 10 is driving, there is a situation of collision with obstacles in the driving path, for example, when the cleaning device 10 enters the area of the bottom of the bed, the bottom of the sofa or the bottom of the tea table for cleaning, it is easy to collide with the obstacles. At this time, it is necessary to obtain the collision information in time, control the cleaning device 10 to stop continuing to drive forward or control the laser sensor to descend, so as to avoid damaging the laser radar. For this purpose, the embodiment of the present disclosure provides a collision detection module 30, which will be described below. Figures 5 to 7 The structure of the collision detection module 30 will be described below.
[0093] AsFigure 5 and Figure 6 As shown in FIGS. 1 and 2, the collision detection module 30 comprises a mounting frame 31, a detector 33, a collision component, and a reset component 35. The detector 33 is arranged on the mounting frame 31, and the collision component is arranged on the mounting frame 31. The collision component can be in a first position relative to the mounting frame 31, which can be regarded as a reset position. After the collision component collides with an obstacle, the collision component moves relative to the mounting frame 31 from the reset position, and can output a collision signal when moving, so that it is determined that the collision detection module 30 collides with the obstacle through the collision signal. The reset component 35 is connected with the collision component when the collision component resets to the reset position, so as to reset the collision component to the reset position, so that the collision detection module 30 can achieve collision detection on multiple obstacles in the driving path of the cleaning device 10 through the reset component 35.
[0094] In an embodiment, as shown in FIGS. 1 and 2, the collision component comprises a collision component 32 and a detector 34. The collision component 32 is arranged on the mounting frame 31 and movably connected with the mounting frame 31. The collision component 32 can be in a first position relative to the mounting frame 31, that is, the collision component 32 is in a reset position relative to the mounting frame 31 in a free state. The detector 34 is arranged on the mounting frame 31 and fixedly or limitingly connected with the mounting frame 31. The detector 34 can be triggered when the collision component 32 moves relative to the reset position after colliding with an obstacle. Figure 5 Figure 6 In an embodiment, as shown in FIGS. 1 and 2, the collision component comprises a collision component 32 and a detector 34. The collision component 32 is arranged on the mounting frame 31 and movably connected with the mounting frame 31. The collision component 32 can be in a first position relative to the mounting frame 31, that is, the collision component 32 is in a reset position relative to the mounting frame 31 in a free state. The detector 34 is arranged on the mounting frame 31 and fixedly or limitingly connected with the mounting frame 31. The detector 34 can be triggered when the collision component 32 moves relative to the reset position after colliding with an obstacle.
[0095] Specifically, after the collision component 32 collides with an obstacle, the collision component 32 can at least move backward in a first direction X and / or move left and right in a second direction Y relative to the mounting frame 31 from the reset position, and the first direction X intersects the second direction Y. When the collision component 32 moves backward along the first direction X or moves left and right along the second direction Y from the reset position, the collision component 32 can trigger the detector 34. It can be understood that the backward movement of the collision component 32 in the first direction X and / or the left and right movement of the collision component 32 in the second direction Y discussed herein is not limited to movement only in the first direction X or the second direction Y. When other parts of the collision component 32 except the parts corresponding to the first direction X and the second direction Y collide with an obstacle, for example, the side front of the collision component 32 collides with an obstacle, the collision component 32 will generate a component of movement in the first direction X and the second direction Y when moving, and at this time, it can be considered that the collision component 32 moves in the first direction X and the second direction Y.
[0096] In an embodiment, the collision detection module 30 comprises a plurality of detectors 34, as shown in FIGS. 1 and 2. Figure 6 Figure 7 As shown, the multiple detectors 34 include a first detector 341 and a second detector 342. When the collision member 32 moves backward from the reset position along the first direction X, the collision member 32 can simultaneously trigger the first detector 341 and the second detector 342. When the collision member 32 moves to the left from the reset position, the collision member 32 can trigger one of the first detector 341 and the second detector 342. When the collision member 32 moves to the right from the reset position, the collision member 32 can trigger the other of the first detector 341 and the second detector 342.
[0097] If both the first detector 341 and the second detector 342 are triggered simultaneously, the system determines that the cleaning device 10 has collided head-on with an obstacle in the forward direction. In this case, the drive module can be controlled to reverse and / or turn, driving the cleaning device 10 quickly away from the obstacle and escaping in time. If only one of the first detector 341 or the second detector 342 is triggered, the system determines that the cleaning device 10 has collided sideways with an obstacle while moving forward. In this case, the drive module can be controlled to reverse and / or turn, driving the cleaning device 10 quickly away from the obstacle and escaping in time, thereby improving cleaning efficiency. The following will use... Figures 6 to 13 The collision detection module 30 is described in further detail.
[0098] like Figure 6 and Figure 7 As shown, in one embodiment, the collision element 32 includes a top cover 321 and a housing 322, with the top cover 321 fixedly connected to the housing 322. The dimensions of the top cover 321 in the first direction X and the second direction Y are larger than those of the housing 322, and the outer edge of the top cover 321 protrudes from the housing 322. When the collision detection module 30 collides with an obstacle, the top cover 321 collides with the obstacle to prevent the detector 33 from directly colliding with the obstacle. After the top cover 321 collides with the obstacle, the force generated by the impact can be transmitted to the housing 322, triggering the detector 34 through the housing 322.
[0099] like Figure 6 As shown, the top cover 321 includes a cover plate 3211 and a buffer member 3212, which are connected together to form the top cover. The buffer member 3212 can be fixedly connected to the housing 322 by a threaded connection, and the cover plate 3211 and the buffer member 3212 can be fixedly connected by, for example, adhesive bonding. In one embodiment, the buffer member 3212 can be made of rubber, and the outer edge of the buffer member 3212 protrudes from the cover plate 3211. When the collision detection module 30 collides with an obstacle, the buffer member 3212 collides with the obstacle, and the buffering effect is achieved by the rubber material buffer member 3212.
[0100] like Figure 6 and Figure 7As shown, the shell 322 comprises a movable part 3221 and a trigger part 3222, the movable part 3221 is movably arranged relative to the mounting frame 31, and the movable part 3221 is fixedly connected with the top cover 321. The movable part 3221 is in a reset position relative to the mounting frame 31 in a free state, and after the top cover 321 collides with the obstacle, the movable part 3221 can be driven by the top cover 321 to move at least away from the reset position in the first direction X and left and right in the second direction Y relative to the mounting frame 31. The trigger part 3222 is connected with the movable part 3221, and the movable part 3221 can drive the trigger part 3222 to move synchronously to trigger the first detector 341 and / or the second detector 342 through the trigger part 3222. In detail, when the cleaning device 10 collides with the obstacle during autonomous movement, the front side collides with the obstacle, and the movable part 3221 drives the trigger part 3222 to trigger the first detector 341 and the second detector 342 at the same time; when the left side of the cleaning device 10 collides with the obstacle, the movable part 3221 drives the trigger part 3222 to trigger the first detector 341; when the right side of the cleaning device 10 collides with the obstacle, the movable part 3221 drives the trigger part 3222 to trigger the second detector 342.
[0101] In an embodiment, the collision member 32 directly contacts the detector 34 to trigger the detector 34. As shown in Figure 6 and Figure 7 As shown, the trigger part 3222 directly contacts the first detector 341 and the second detector 342 when triggering the first detector 341 and the second detector 342, which improves the reliability of triggering the first detector 341 and the second detector 342.
[0102] As shown in Figure 6 and Figure 7 As shown, the movable part 3221 comprises a transparent part 32214 and a connecting part 32216, which can be fixedly connected by, for example, insertion, adhesion, clamping, etc., or can be an integrally formed structure. The buffer member 3212 can be fixedly connected with the connecting part 32216 through a threaded member, thereby realizing the top cover 321 and the shell 322.
[0103] In an embodiment, as shown in Figure 8 and Figure 9As shown, the detector 33 is located in the accommodating groove 32211 of the movable part 3221, when the detector 33 is a laser radar, the laser radar can detect the obstacle on the travel path of the cleaning device 10 through the transparent part 32214. The shell 322 can be formed of transparent material as a whole, or a transparent window is formed of transparent material at the position corresponding to the laser radar. In an embodiment, the part of the movable part 3221 except the transparent part 32214 and the trigger part 3222 can be formed of translucent or non-transparent material, thus the two-color injection molding process can be adopted to form the shell 322, that is, the transparent material and the non-transparent material are injected into the same set of molds. For example, the transparent part 32214 is formed of transparent material such as polymethyl methacrylate (PMMA), and the part of the shell 322 except the transparent part 32214 is formed of translucent or non-transparent material such as polypropylene (PP) or polyethylene (PE), so as to realize the injection molding of the shell 322 with the transparent part 32214, and the shell 322 with the transparent part 32214 is formed in one piece.
[0104] As shown in FIG. 3, the trigger part 3222 is provided with a first detector 341 and a second detector 342. Figure 10 As shown in an embodiment, the reset member 35 is located between the trigger part 3222 and the mounting frame 31. When the cleaning device 10 does not collide with the obstacle during the autonomous movement, the collision member 32 is in the reset position by the reset force of the reset member 35, that is, the trigger part 3222 is not in contact with or does not trigger the first detector 341 and the second detector 342. When the cleaning device 10 collides with the obstacle during the autonomous movement, the trigger part 3222 moves relative to the first detector 341 and / or the second detector 342 to trigger the first detector 341 and / or the second detector 342 by overcoming the reset force provided by the reset member 35.
[0105] In an embodiment, the reset member 35 can be a first elastic member, that is, when the cleaning device 10 does not collide with the obstacle during the autonomous movement, the collision member 32 is in the reset position by the elastic force of the first elastic member. When the cleaning device 10 collides with the obstacle during the autonomous movement, the trigger part 3222 triggers the first detector 341 and / or the second detector 342 by overcoming the elastic force provided by the first elastic member.
[0106] As shown in FIG. 3, the trigger part 3222 is provided with a first detector 341 and a second detector 342. Figure 10As shown, the reset member 35 can be a spring. When the cleaning device 10 collides with an obstacle during autonomous movement, the trigger portion 3222 compresses the spring to trigger the first detector 341 and / or the second detector 342; when the cleaning device 10 does not collide with an obstacle during autonomous movement, at this time the trigger portion 3222 is driven by the elastic restoring force of the spring to bring the collision member 32 to the reset position. The structure of the spring is stable, which can provide a stable elastic reset force, so that the collision member 32 can be stably in the reset position.
[0107] As shown in Figure 10 , the mounting frame 31 is provided with a first positioning structure 3112, and the trigger portion 3222 is provided with a second positioning structure 32222, and the two ends of the spring are sleeved on the first positioning structure 3112 and the second positioning structure 32222 respectively to realize positioning assembly. The first positioning structure 3112 and the second positioning structure 32222 can be protruding structures or recessed structures, which can realize positioning assembly of the ends of the spring, and the present disclosure does not limit this.
[0108] When the spring is assembled between the trigger portion 3222 of the collision member 32 and the mounting frame 31, the spring can be in a compressed state when the collision member 32 is in the reset position, that is, a pre-tightening force can be provided by the spring, and when the collision member 32 is subjected to a collision force greater than the pre-tightening force, the spring will be compressed to move, so that the collision member 32 can be more stably in the reset position as shown in Figure 11 .
[0109] It can be understood that the first elastic member can also be a tension spring, and when the cleaning device 10 collides with an obstacle during autonomous movement, the trigger portion 3222 stretches the tension spring to trigger the first detector 341 and / or the second detector 342 by moving.
[0110] In an embodiment, the trigger portion 3222 is rotationally connected with the mounting frame 31, and when the movable portion 3221 moves left and right relative to the mounting frame 31 in the second direction Y, the moving direction of the movable portion 3221 is opposite to that of the trigger portion 3222. As shown in Figure 12 , when the left front of the top cover 321 of the collision member 32 collides with an obstacle during autonomous movement of the cleaning device 10, at this time the movable portion 3221 of the collision member 32 moves toward the right rear under the action of inertia, and the trigger portion 3222 is driven by the movable portion 3221 to rotate toward the left side, thereby triggering the first detector 341 arranged on the left side. As shown in Figure 13As shown, when the front of the top cover 321 of the collision member 32 collides with an obstacle during autonomous movement of the cleaning device 10, the movable part 3221 of the collision member 32 moves toward the back under the action of inertia, and the trigger part 3222 moves toward the back under the action of the movable part 3221, thereby triggering the first detector 341 and the second detector 342 at the same time. Figure 14 As shown, when the front of the top cover 321 of the collision member 32 collides with an obstacle during autonomous movement of the cleaning device 10, the movable part 3221 of the collision member 32 moves toward the back under the action of inertia, and the trigger part 3222 moves toward the back under the action of the movable part 3221, thereby triggering the first detector 341 and the second detector 342 at the same time.
[0111] In an embodiment, a rotating structure is arranged between the trigger part and the mounting frame 31, and the movable part 3221 is rotatably connected to the mounting frame 31 through the rotating structure. When the front of the collision member 32 collides with an obstacle during autonomous movement of the cleaning device 10, the movable part 3221 of the collision member 32 can move toward the back through the rotating structure, and the trigger part 3222 moves toward the back under the action of the movable part 3221, thereby triggering the first detector 341 and the second detector 342 at the same time. When the left front of the collision member 32 collides with an obstacle during autonomous movement of the cleaning device 10, the movable part 3221 of the collision member 32 moves toward the right back, and the trigger part 3222 can rotate toward the left through the rotating structure under the action of the movable part 3221, thereby triggering the first detector 341 arranged at the left. When the right front of the collision member 32 collides with an obstacle during autonomous movement of the cleaning device 10, the movable part 3221 of the collision member 32 moves toward the left back under the action of inertia, and the trigger part 3222 can rotate toward the right through the rotating structure under the action of the movable part 3221, thereby triggering the second detector 342 arranged at the right. The following will be described by taking the rotating structure as an example. Figures 15 to 17 The structure that the trigger part 3222 is rotatably connected to the mounting frame 31 will be described in detail.
[0112] In an embodiment, the rotating structure includes a rotating protrusion and a rotating groove, one of the rotating protrusion and the rotating groove is arranged on the trigger part 3222, and the other is arranged on the mounting frame 31; the rotating protrusion is located in the rotating groove and can move a preset distance in the rotating groove along the first direction X. Through the rotating cooperation of the rotating protrusion and the rotating groove and the ability to move a preset distance in the rotating groove along the first direction X, the rotating connection of the collision member 32 and the mounting frame 31 is realized. As shown, Figure 15 As shown, the rotating groove 32221 is arranged on the trigger part 3222; as shown, Figure 16 As shown, the rotating protrusion 3111 is arranged on the mounting frame 31.
[0113] The rotating protrusion 3111 can move a preset distance along the first direction X in the rotating groove 32221. This ensures that when the cleaning device 10 collides with an obstacle in front during autonomous movement, the trigger part 3222, driven by the movable part 3221, moves backward to simultaneously trigger the first detector 341 and the second detector 342. Furthermore, by setting the length of the rotating groove 32221 along the first direction X, when the collision member 32 is in the reset position, the rotating groove 32221 limits the rotating protrusion 3111, thereby limiting the relative movement between the collision member 32 and the mounting bracket 31 along the first direction X. This allows the first elastic member located between the trigger part 3222 and the mounting bracket 31 to be in a compressed state, providing a preload force so that the collision member 32 can be more stably positioned in the reset position.
[0114] like Figure 17 As shown, in one embodiment, the rotating protrusion 3111 is cylindrical. The cylindrical shape of the rotating protrusion 3111 facilitates its rotation in the rotating groove 32221, reduces resistance in the rotation direction, and thus improves the detection accuracy of the collision position.
[0115] In one embodiment, in the second direction Y, the width of the rotating groove 32221 is 100% to 110% of the width of the rotating protrusion 3111, that is, the rotating protrusion 3111 can only move in the rotating groove 32221 along the first direction X, and can only rotate relative to each other in the second direction Y or can only move a very small distance along the second direction Y, for example, less than 2 mm. The following will explain... Figures 16 to 19 The structure of the collision component 32 and the mounting bracket 31 is described in detail.
[0116] In one embodiment, such as Figure 16 As shown, the movable part 3221 has a receiving groove 32211; as Figure 17 As shown, the mounting bracket 31 includes a base portion 311 and a second limiting portion 312 disposed on the base portion 311, the second limiting portion 312 being located in the receiving groove 32211. When the collision member 32 is in the reset position, the distances between the two sides of the second limiting portion 312 and the groove wall of the receiving groove 32211 are the same or substantially the same in the first direction X and the second direction Y. When the cleaning device 10 collides with an obstacle during autonomous movement, the movable portion 3221 of the collision member 32 can move the same or substantially the same distance along the first direction X and the second direction Y, thereby ensuring that the second limiting portion 312 is located at the center of the receiving groove 32211 when the collision member 32 is in the reset position.
[0117] In one embodiment, such as Figure 16 As shown, the receiving groove 32211 is circular; as Figure 17As shown, the second limiting portion 312 is in a cylindrical shape. When the collision member 32 is in the reset position, the outer circumferential surface of the second limiting portion 312 has the same or substantially the same distance from the groove wall of the accommodation groove 32211 in the circumferential direction. When the collision member 32 collides with the obstacle during the autonomous movement of the cleaning device 10, the movable portion 3221 of the collision member 32 can move the same or substantially the same distance in the direction of impact, so that the second limiting portion 312 is located at the center of the accommodation groove 32211 when the collision member 32 is in the reset position.
[0118] As shown in Figure 18 , the second limiting portion 312 is provided with a blocking portion 3123. When the collision member 32 moves towards the reset position under the action of the reset member 35, the blocking portion 3123 forms a limiting block to the movable portion 3221, and when the blocking portion 3123 abuts against the groove wall of the accommodation groove 32211 on the movable portion 3221, the first elastic member is in a compressed state, and the first elastic member provides a pre-tightening force to enable the collision member 32 to be more stably in the reset position.
[0119] As shown in Figure 19 , the inner wall of the accommodation groove 32211 of the collision member 32, which abuts against the blocking portion 3123, is provided with a limiting groove 32213. When the blocking portion 3123 forms a limiting block to the movable portion 3221, the blocking portion 3123 is located in the limiting groove 32213, forming a relative movement between the movable portion 3221 and the second limiting portion 312 in the circumferential direction of the second limiting portion 312. For example, the blocking portion 3123 can have an arc-shaped protrusion structure, and the limiting groove 32213 can have an arc-shaped recess structure. In an embodiment, when the collision member 32 is in the reset position, the blocking portion 3123 is located in the limiting groove 32213 and abuts against or has a small gap, for example, less than 5mm, with the groove wall of the limiting groove 32213.
[0120] In an embodiment, a limiting structure is provided between the movable portion 3221 of the collision member 32 and the second limiting portion 312 of the mounting frame 31, and the limiting structure is used to limit the downward movement of the movable portion 3221 relative to the mounting frame 31 in the third direction Z, which is perpendicular to the first direction X and the second direction Y, i.e., the third direction Z can be the height direction of the collision detection module 30. When the collision member 32 moves, a limiting block to the collision member 32 in the height direction is formed, thereby avoiding the movement of the collision member 32 in the height direction. The limiting structure between the collision member 32 and the mounting frame 31 will be described in detail below. Figures 16 to 19 The limiting structure between the collision member 32 and the mounting frame 31 will be described in detail below.
[0121] In an embodiment, the limiting structure comprises a limiting protrusion 3121 and a limiting slot 32212, one of which is arranged on the movable part 3221 and the other is arranged on the mounting frame 31; the limiting protrusion 3121 is located in the limiting slot 32212 and can move a preset distance in the limiting slot 32212 along the first direction X and the second direction Y, forming an avoidance of the limiting protrusion 3121 moving in the limiting slot 32212 under the action of inertial force, and only forming a limit in the height direction.
[0122] As shown in Figure 16 , the movable part 3221 comprises a first limiting part 32215 located below the transparent part 32214, and the limiting slot 32212 is arranged on the first limiting part 32215 of the movable part 3221; as shown in Figure 17 , the limiting protrusion 3121 is arranged on the second limiting part 312, and when the first limiting part 32215 and the second limiting part 312 are sleeved, it is convenient for the limiting protrusion 3121 to be located in the limiting slot 32212 when the impact piece 32 and the mounting frame 31 are assembled.
[0123] As shown in Figure 16 , the limiting slot 32212 can be an arc-shaped slot, and its extension direction is along the annular slot wall of the accommodating slot 32211; as shown in Figure 17 and Figure 18 , the limiting protrusion 3121 and the limiting slot 32212 are matched in shape, so that the limiting protrusion 3121 and the second limiting part 312 have high connection strength.
[0124] In an embodiment, a plurality of limiting protrusions 3121 are arranged on the outer circumferential surface of the second limiting part 312, and a plurality of limiting slots 32212 are arranged on the slot wall of the accommodating slot 32211 in one circle in the circumferential direction, and the plurality of limiting protrusions 3121 are one-to-one corresponding to the limiting slots 32212. Among them, at least one of the plurality of limiting slots 32212 can be a through hole structure, that is, the limiting slot 32212 is directly formed through the through hole on the movable part 3221, so as to facilitate the assembly and disassembly of the impact piece 32 and the mounting frame 31. As shown in Figure 18 and Figure 19 , three limiting protrusions 3121 are arranged on the outer circumferential surface of the second limiting part 312, and three limiting slots 32212 are arranged on the slot wall of the accommodating slot 32211 in one circle in the circumferential direction, wherein two limiting slots 32212 close to the trigger part 3222 can be through holes, and the remaining one can be a counterbore. The free ends of the two limiting protrusions 3121 arranged in the limiting slot 32212 can be provided with inclined surfaces, so as to facilitate the entry and exit of the limiting protrusion 3121 in the limiting slot 32212 when the impact piece 32 and the mounting frame 31 are assembled and disassembled.
[0125] As shown in Figure 18As shown, the limiting protrusion 3121 can be connected to the second limiting part 312 via the elastic arm 3122, so that when the collision member 32 is assembled and disassembled with the mounting bracket 31, the deformation of the elastic arm 3122 can facilitate the entry and exit of the limiting protrusion 3121 in the limiting groove 32212.
[0126] In one embodiment, a plurality of limiting protrusions 3121 are evenly distributed on the outer peripheral surface of the second limiting portion 312. For example, three limiting protrusions 3121 are provided on the outer peripheral surface of the second limiting portion 312, and three limiting grooves 32212 are provided around the circumference of the groove wall of the receiving groove 32211. The three limiting protrusions 3121 are evenly distributed on the outer peripheral surface of the second limiting portion 312, and the three limiting grooves 32212 are evenly distributed around the circumference of the groove wall of the receiving groove 32211. Of course, two, four, five or more limiting protrusions 3121 may be provided on the outer peripheral surface of the second limiting portion 312, and the number of limiting grooves 32212 matches the number of limiting protrusions 3121; the plurality of limiting protrusions 3121 may also be non-uniformly distributed on the outer peripheral surface of the second limiting portion 312, and this disclosure does not limit this. The following will be explained by Figures 20 to 23 The first detector 341 and the second detector 342 are described in detail.
[0127] like Figure 20 As shown, in one embodiment, at least one of the first detector 341 and the second detector 342 includes a detector body 343 and a trigger key 344. The trigger key 344 has an initial position and a detection position relative to the detector body 343. When the collision member 32 moves relative to the mounting bracket 31, the trigger part 3222 can press the trigger key 344 to be in the detection position. When the trigger key 344 is in the detection position, the circuit of the detector body 343 is turned on, thereby emitting a collision signal. By judging the collision signals in the first detector 341 and the second detector 342, the collision direction of the cleaning equipment 10 can be indirectly determined.
[0128] like Figure 20 As shown, in one embodiment, at least one of the first detector 341 and the second detector 342 further includes a second elastic member 345, which is located between the trigger portion 3222 and the trigger key 344. When the collision member 32 moves relative to the mounting bracket 31, the trigger portion 3222 can squeeze the second elastic member 345 so that the second elastic member 345 squeezes the trigger key 344 to be in the detection position. When the collision member 32 is in the reset position, the second elastic member 345 separates from the trigger key 344 by elastic restoring force, or does not make the trigger key 344 in the detection position.
[0129] It can be understood that when the trigger key 344 is located at the detection position, the circuit of the detector body 343 and the trigger key 344 is turned on, so as to send a collision signal, and when the collision signal of the first detector 341 and the second detector 342 is determined, the impact angle of the collision member 32 can be determined. It can be determined that the collision member 32 collides with the obstacle in the front, or collides with the obstacle in the left front, or collides with the obstacle in the right front.
[0130] In the determination of the impact position, as shown in Figure 21 for example, when the part corresponding to the included angle A1 of the left and right sides in front of the cleaning device 10 and the central axis angle is in the range of 0-15° collides with the obstacle, the collision member 32 can trigger the first detector 341 and the second detector 342 at the same time to determine that the cleaning device 10 collides with the obstacle in the front. When the left side in front of the cleaning device 10 and the central axis angle corresponding to the included angle A2 in the range of 15°-90° collides with the obstacle, the collision member 32 can trigger the first detector 341 to determine that the left front of the cleaning device 10 collides with the obstacle. When the right side in front of the cleaning device 10 and the central axis angle corresponding to the included angle A3 in the range of 15°-90° collides with the obstacle, the collision member 32 can trigger the second detector 342 to determine that the right front of the cleaning device 10 collides with the obstacle.
[0131] In order to more accurately determine the collision position of the cleaning device 10 and the obstacle, in an embodiment, the trigger key 344 includes a plurality of detection positions relative to the detector body 343, and when the collision member 32 moves relative to the mounting frame 31, the trigger part 3222 can be in different detection positions under different extrusion forces by the trigger key 344.
[0132] In detail, as shown in Figure 22As shown, for example, the trigger key 344 relative to the detector body 343 includes a first detection position and a second detection position. When, for example, the part corresponding to the angle B1 within the range of 0-15° with the central axis in front of the cleaning device 10 collides with the obstacle, the collision member 32 can trigger the first detector 341 and the second detector 342 at the same time, so that the trigger key 344 of the first detector 341 and the second detector 342 is in the first detection position or the second detection position at the same time, so as to determine that the cleaning device 10 collides with the obstacle head-on. When the part corresponding to the angle B2 within the range of 15°-45° with the central axis on the left side in front of the cleaning device 10 collides with the obstacle, the collision member 32 can trigger the first detector 341, and the trigger key 344 of the first detector 341 is in the first detection position, so as to determine that the part corresponding to the angle B2 on the left side in front of the cleaning device 10 collides with the obstacle. When the part corresponding to the angle B3 within the range of 45°-90° with the central axis on the left side in front of the cleaning device 10 collides with the obstacle, the collision member 32 can trigger the first detector 341, and the trigger key 344 of the first detector 341 is in the second detection position, so as to determine that the part corresponding to the angle B3 on the left side in front of the cleaning device 10 collides with the obstacle, thereby achieving further accurate determination of the collision position. When the part corresponding to the angle B4 within the range of 15°-45° with the central axis on the right side in front of the cleaning device 10 collides with the obstacle, the collision member 32 can trigger the second detector 342, and the trigger key 344 of the second detector 342 is in the first detection position, so as to determine that the part corresponding to the angle B4 on the right side in front of the cleaning device 10 collides with the obstacle. When the part corresponding to the angle B5 within the range of 45°-90° with the central axis on the right side in front of the cleaning device 10 collides with the obstacle, the collision member 32 can trigger the second detector 342, and the trigger key 344 of the second detector 342 is in the second detection position, so as to determine that the part corresponding to the angle B5 on the right side in front of the cleaning device 10 collides with the obstacle, thereby achieving further accurate determination of the collision position.
[0133] It can be understood that, for example, the trigger key 344 relative to the detector body 343 can also include a third detection position or more detection positions to more accurately determine the collision angle of the collision member 32, which is not limited in the present disclosure.
[0134] In an embodiment, at least one of the first detector 341 and the second detector 342 is clamped with the mounting frame 31. For example, as shown in FIG. 4, the first detector 341 is clamped with the mounting frame 31, and the second detector 342 is clamped with the mounting frame 31. Figure 23As shown, the mounting frame 31 can be provided with oppositely arranged clamping arms 3113, and a clamping space is formed between the oppositely arranged clamping arms 3113. The first detector 341 and the second detector 342 can be arranged in a clamping space, respectively. The end of the clamping arm 3113 is provided with a clamping hook. The clamping hook can be abutted against the top surface of the detector by deforming the clamping arm 3113, so as to form the fixing of the detector. The first detector 341 and the second detector 342 are installed in the form of clamping, which can improve the assembly efficiency and facilitate the later maintenance. Of course, the first detector 341 and the second detector 342 can also be fixedly connected in the form of adhesion, threaded connection, etc. The present disclosure does not limit this.
[0135] In an embodiment, as shown in Figure 23 The mounting frame 31 is provided with a positioning column 3114, and the first detector 341 and the second detector 342 are respectively provided with a positioning hole. The positioning hole and the positioning column 3114 are matched to form the positioning and assembly of the first detector 341 and the second detector 342 on the mounting frame 31, so as to improve the assembly accuracy and the assembly efficiency. The positioning hole and the positioning column 3114 can be provided in plurality, and the plurality of positioning columns 3114 are correspondingly arranged in the plurality of positioning holes to form the positioning in the first direction X and the second direction Y. The clamping arm 3113 is matched to realize the positioning and assembly in three directions, so that the assembly position of the first detector 341 and the second detector 342 on the mounting frame 31 is unique, thereby further improving the assembly efficiency. For example, the positioning hole and the positioning column 3114 can be provided in two, respectively, so as to realize the assembly positioning in the first direction X and the second direction Y, and avoid arranging too many positioning structures on the first detector 341, the second detector 342 and the mounting frame 31, thereby reducing the production cost. The driving assembly 36 for driving the probe 33 to ascend and descend will be described in detail below. Figure 24 and Figure 25 The driving assembly 36 for driving the probe 33 to ascend and descend will be described in detail below.
[0136] As shown in Figure 24 The driving assembly 36 includes a driver 361, a transmission rod 362, a first rocker arm 363 and a second rocker arm 364. The output shaft of the driver 361 is connected with the transmission rod 362 and coaxially arranged, that is, the transmission rod 362 can rotate under the driving of the driver 361. The first rocker arm 363 is arranged on the transmission rod 362 and fixedly connected with the transmission rod 362 in the rotation direction. One end of the second rocker arm 364 is rotationally connected with the base portion 311 of the mounting frame 31, and the other end is rotationally connected with the first rocker arm 363. The second rocker arm 364 and the first rocker arm 363 form a hinge-like structure, that is, the distance between the two ends of the first rocker arm 363 and the second rocker arm 364 can be changed by rotating the first rocker arm 363.
