In the description of the embodiments of the present application, the meaning of "multiple" is at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.

[0031] The present application embodiment provides a cleaning device, see Figures 1 to 6 The cleaning device 100 includes a housing 1, a telescopic assembly 2, a circuit board 3, a protective cover 4, and a fan. The telescopic assembly 2 includes a motor 21, a transmission mechanism 22, and a protruding member 23. The transmission mechanism 22 and the motor 21 are both located in the housing 1. The transmission mechanism 22 is configured to drive the protruding member 23 to extend out of the housing 1 or retract into the housing 1 under the drive of the motor 21. The circuit board 3 is located in the housing 1 and is electrically connected to the motor 21. The protective cover 4 at least covers the circuit board 3. The fan is disposed in the housing 1, and the air outlet of the fan faces the protective cover 4.

[0032] The cleaning device 100 provided in the embodiment of the present application, by arranging the motor 21, transmission mechanism 22, circuit board 3 and fan in the housing 1, can protect the motor 21, transmission mechanism 22, circuit board 3 and fan to a certain extent, thereby improving their protection life. The transmission mechanism 22 is driven by the motor 21 to drive the protrusion 23 to extend or retract into the housing 1. In this way, the protrusion 23 can be retracted into the housing 1 when not in use or to avoid objects, thereby improving the protection of the protrusion 23. By arranging the circuit board 3 to be connected to the motor 21, at least part of the protective cover 4 is covered on the circuit board 3, and the air outlet of the fan is facing the protective cover 4. In this way, the protective cover 4 can block the gas blown out of the air outlet of the fan, reduce the situation where dust and other foreign matter enter the circuit board 3 and its function fails or is limited, and can improve the working stability of the circuit board 3 and the telescopic component 2.

[0033] Exemplarily, in one embodiment, the shell 1 is formed with a accommodating space 1a and an opening 1b connected to the accommodating space 1a, and the motor 21, the transmission mechanism 22, the circuit board 3 and the fan are all arranged in the accommodating space 1a, and the transmission mechanism 22 is driven by the motor 21 to drive the protrusion 23 to extend or retract into the accommodating space 1a.

[0034] For example, in one embodiment, the cleaning device 100 may be a sweeping robot.

[0035] For example, in one embodiment, foreign matter may also include hair, gravel, paper scraps, etc.

[0036] Exemplarily, in one embodiment, the extension and retraction directions of the protruding member 23 and the extension and retraction directions of the protruding member 23 may be top-bottom directions.

[0037] It should be noted that the top points to the ceiling, and the bottom is in the opposite direction of the top.

[0038] Illustratively, in one embodiment, the opening direction of the opening 1b may be set toward the top.

[0039] For example, in one embodiment, Figure 2 R1 in can be top or bottom direction.

[0040] For example, in one embodiment, the shape of the housing 1 is not limited. For example, the projection shape of the housing 1 along the top and bottom directions may be circular.

[0041] In one embodiment, the protruding member 23 is a laser radar. When the motor 21 drives the transmission mechanism 22 to extend the protruding member 23 from the opening 1b out of the accommodating space 1a, the laser radar can sense the surrounding environment and obtain a three-dimensional model of the surrounding environment. The cleaning device 100 can then create a map based on the obtained three-dimensional model data and plan the optimal cleaning path based on the map, thereby improving the cleaning ability and efficiency of the cleaning device 100.

[0042] For example, in one embodiment, please refer to Figure 1 Cleaning device 100 includes a partition 5 disposed within storage space 1a to divide storage space 1a into a first cavity 1a1 and a second cavity 1a2. A motor 21, transmission mechanism 22, circuit board 3, protective cover 4, and fan are all disposed within first cavity 1a1, which communicates with opening 1b. Housing 1 defines a dust collection port, which communicates with second cavity 1a2. A dust bag is disposed within second cavity 1a2, with the dust bag inlet communicating with the dust collection port and the dust bag outlet communicating with the fan inlet. The fan is driven to collect dust and other foreign matter in the dust bag.

[0043] In one embodiment, please refer to Figures 1 to 3 The telescopic assembly 2 includes a shell 24 arranged in the shell body 1, the protrusion 23 is arranged in the shell 24, the shell 24 is formed with an avoidance opening 24b connected to its interior, part of the transmission mechanism 22 is arranged in the shell 24, and the other part of the transmission mechanism 22 passes through the avoidance opening 24b and is driven and connected to the motor 21.

[0044] Illustratively, the casing 24 may be disposed in the first cavity 1 a 1 .

[0045] Here, by arranging the protruding piece 23 in the enclosure 24, the protruding piece 23 positioned in the telescopic cavity can be protected to further improve its service life. By arranging the avoidance opening 24b, the movement of the transmission mechanism 22 can be avoided to reduce the structural interference with the transmission mechanism 22.

[0046] Exemplarily, in one embodiment, the shell 24 is formed with a telescopic cavity and a telescopic opening 24c, the avoidance opening 24b and the telescopic opening 24c are both connected to the telescopic cavity, the telescopic opening 24c is connected to the opening 1b, the protrusion 23 is arranged in the telescopic cavity, part of the transmission mechanism 22 is arranged in the telescopic cavity, and the other part of the transmission mechanism 22 passes through the avoidance opening 24b and is driven and connected to the motor 21.

[0047] In this way, by providing the telescopic opening 24c to communicate with the opening 1b, the protruding member 23 can enter and exit the opening 1b through the telescopic opening 24c.

[0048] For example, in one embodiment, the opening direction of the avoidance opening 24b and the opening direction of the telescopic opening 24c can be perpendicular to each other, so as to avoid structural interference between the protruding member 23 and the transmission mechanism.

[0049] Exemplarily, in one embodiment, the shape of the enclosure 24 is not limited. Specifically, along the top-bottom direction, the projection shape of the enclosure 24 matches the projection shape of the protruding piece 23 .

[0050] In one embodiment, please refer to Figure 4 A slider is formed on the inner wall of the shell 24 and one of the protruding pieces 23, and a slide groove 23a is formed on the inner wall of the shell 24 and one of the protruding pieces 23. The slider slides with the slide groove 23a in the telescopic direction of the protruding piece 23.

[0051] For example, in one embodiment, the wall of the telescopic cavity can be formed with a slider extending along the telescopic direction of the protrusion 23. A chute 23a can be formed around the periphery of the protrusion 23, and the chute 23a and the slider can slide in conjunction. This not only provides a smooth and accurate movement path, but also allows the slider to slide easily within the chute 23a, making the entire movement process more precise and controllable. Furthermore, the chute 23a provides additional support and stability, preventing the slider from shaking or sliding unsteadily during movement, ensuring stable movement.

[0052] In one embodiment, please refer to Figures 2 to 4 An opening 1b is formed in the shell 1 and is connected to the interior thereof. The protrusion 23 can extend or retract into the shell 1 through the opening 1b. A closing cover 23b is provided on the side of the protrusion 23 away from the shell 1. Along the projection of the extension and retraction direction of the protrusion 23, the projection area of ​​the opening 1b is located within the projection area of ​​the closing cover 23b.

[0053] For example, the closure cover 23b can be disposed on the side of the protruding member 23 that faces away from the accommodating space 1a along the direction in which the protruding member 23 extends. Here, when the motor 21 drives the transmission mechanism 22 to retract the protruding member 23 into the accommodating space 1a, the closure cover 23b can cover the opening 1b. In this way, the closure cover 23b can reduce the ingress of dust and other foreign matter into the accommodating space 1a through the opening 1b after the protruding member 23 is retracted into the accommodating space 1a, thereby improving the protection of the components within the accommodating space 1a and extending the service life of the components.

[0054] In one embodiment, please refer to Figure 2 and Figure 3The cleaning device 100 also includes a vertical plate 6 arranged in the shell 1, the circuit board 3, part of the transmission mechanism 22 and the protective cover 4 are stacked in sequence on one side of the vertical plate 6, and the motor 21 is arranged on the other side of the vertical plate 6. The output shaft of the motor 21 passes through the vertical plate 6 and is connected to the transmission mechanism 22, so that part of the transmission mechanism 22 can move between the circuit board 3 and the protective cover 4.

[0055] Exemplarily, one end of the vertical plate 6 can be set on the surface outside the shell 24 near the avoidance opening 24 b, and the other end of the vertical plate 6 extends in a direction away from the shell 24. The circuit board 3 can be arranged on the side of the vertical plate 6 close to the fan along the thickness direction of the vertical plate 6, the base of the motor 21 can be arranged on the side of the vertical plate 6 away from the circuit board 3 along the thickness direction of the vertical plate 6, the output shaft of the motor 21 passes through the vertical plate 6 along the thickness direction of the vertical plate 6, the part of the transmission mechanism 22 passing through the avoidance opening 24b can be arranged on the side of the circuit board 3 close to the fan along the thickness direction of the vertical plate 6, and is driven and connected to the output shaft of the motor 21, and the protective cover 4 can be arranged on the side of the part of the transmission mechanism 22 passing through the avoidance opening 24b close to the fan along the thickness direction of the vertical plate 6. In this way, the driving transmission action between the part of the transmission mechanism 22 and the output shaft can be carried out between the circuit board 3 and the protective cover 4. On the one hand, the noise during transmission can be reduced to a certain extent, making the cleaning device 100 quieter when working; on the other hand, the influence of foreign matter such as dust on the transmission work can be reduced, thereby improving the reliability of the transmission; on the other hand, it is conducive to the rational utilization of the overall space in the cleaning device 100, with a compact structure and high space utilization.

[0056] For example, in one embodiment, the casing 24 and the vertical plate 6 may be integrally formed, thereby increasing the connection strength between the vertical plate 6 and the casing 24 and improving the support and load-bearing capacity of the vertical plate 6 .

[0057] In one embodiment, please refer to Figures 4 to 6 The transmission mechanism 22 includes a first link 221, a second link 222, a third link 223 and a fourth link 224. The first link 221 is connected to the output shaft, one end of the second link 222 is hinged to one end of the first link 221, and the other end of the second link 222 is hinged to one end of the third link 223 and one end of the fourth link 224 respectively. The other end of the third link 223 is hinged to the side of the shell 1 away from the protrusion 23, and the other end of the fourth link 224 is hinged to the protrusion 23. Part of the first link 221 can move between the circuit board 3 and the protective cover 4.

[0058] Illustratively, a rotary hole is formed in the middle of the length of the first connecting rod 221, and the output shaft is inserted into the rotary hole to transmit torque. One end of the first connecting rod 221 along its length is located between the circuit board 3 and the protective cover 4. One end of the second connecting rod 222 can be hinged to the other end of the first connecting rod 221 along its length. The other end of the second connecting rod 222 along its length is hinged to one end of the third connecting rod 223 and one end of the fourth connecting rod 224, respectively. The other end of the third connecting rod 223 along its length is hinged to the wall of the accommodating space 1a on the side away from the opening 1b along the extension direction of the protruding member 23. The other end of the fourth connecting rod 224 along its length is hinged to the protruding member 23. That is to say, the hinge point between the fourth link 224 and the protrusion 23 and the hinge point between the third link 224 and the shell 1 are arranged at intervals along the extension and retraction direction of the protrusion 23, while the hinge point between the second link 222 and the third link 223 and the hinge point between the second link 222 and the fourth link 224 are both located between the hinge point between the third link 223 and the protrusion 23 and the hinge point between the fourth link 224 and the shell 1.

[0059] In this way, since the first connecting rod 221 is connected to the output shaft, it is equivalent to being fixed, and one end of the third connecting rod 223 is hinged to the housing 1, which is also equivalent to being fixed, and the second connecting rod 222 is hinged to the first connecting rod 221 and the third connecting rod 223 respectively. In this way, the first connecting rod 221, the second connecting rod 222 and the third connecting rod 223 are equivalent to forming a four-bar structure. When the motor 21 drives the first connecting rod 221 to rotate through its output shaft, that is, the first connecting rod 221 at this time is equivalent to a crank, and the first connecting rod 221 can The second link 222 drives the third link 223 to swing about its hinge point with the housing 1. In this case, the third link 223 acts as a rocker. One end of the fourth link 224 is hinged to the hinge point between the second link 222 and the third link 223, and the other end of the fourth link 224 is hinged to the protruding member 23. In this way, the swinging motion of the third link 223 is converted into the fourth link 224 pushing the protruding member 23 in the direction of extension and retraction of the protruding member 23 to extend or retract the opening 1b. In this way, the extension and retraction of the protruding member 23 are achieved through the link structure, which is compact and has relatively smooth transmission.

[0060] For example, in one embodiment, when the output shaft rotates clockwise, the protrusion 23 may extend out of the accommodation space 1a through the opening 1b, and when the output shaft rotates counterclockwise, the protrusion 23 may retract into the accommodation space 1a through the opening 1b.

[0061] In one embodiment, please refer to Figure 2 and Figure 3 The surface of the vertical plate 6 is further provided with a first limiting member 61 and a second limiting member 62. The first limiting member 61 and the second limiting member 62 are respectively provided on the rotation path of the first connecting rod 221.

[0062] For example, the first stopper 61 and the second stopper 62 can both be disposed on the side of the vertical plate 6 along the thickness direction thereof, close to the fan. The first connecting rod 221 has an extension limit position in which the protruding member 23 is extended to the limit, and a retraction limit position in which the protruding member 23 is retracted to the limit in the rotation direction. The first stopper 61 can block the first connecting rod 221 when it rotates to the extension limit position, and the second stopper 62 can block the first connecting rod 221 when it rotates to the retraction limit position.

[0063] In this way, by setting the first limit member 61 and the second limit member 62, the situation in which the first connecting rod 221 excessively rotates and causes structural interference between the first connecting rod 221 and the second connecting rod 222, and the situation in which the protrusion 23 is not extended or retracted into place can be reduced, and the working stability is good.

[0064] For example, in one embodiment, please refer to Figures 3 to 6 The cleaning device 100 includes two position sensors 7 and a controller. The controller is electrically connected to the position sensors 7 and the motor 21, respectively. The two position sensors 7 can be both arranged on the circuit board 3. Both position sensors 7 have a sensing slot 7a therein. The two position sensors 7 are respectively an extension sensor 71 and a retraction sensor 72. The first connecting rod 221 forms a stopper 2211 at the end thereof hinged with the second connecting rod 222. When the stopper 2211 rotates to the sensing slot 7a in the extension sensor 71, the extension sensor 71 can transmit an extension-in-place signal to the controller. After receiving the extension-in-place signal, the controller controls the motor 21 to turn off. When the stopper 2211 rotates to the sensing slot 7a in the retraction sensor 72, the retraction sensor 72 can transmit a retraction-in-place signal to the controller. After receiving the retraction-in-place signal, the controller controls the motor 21 to turn off. In this way, the situation where the protruding member 23 cannot be extended or retracted can be reduced, and the degree of automation is high.

[0065] For example, in one embodiment, please refer to Figures 3 to 6 The first limit member 61 corresponds to the extension sensor 71, and the second limit member 62 corresponds to the retraction sensor 72. That is to say, when the sensing slot 7a of the extension sensor 71 senses the block 2211, the motor 21 can be controlled to be closed by the controller to reduce the occurrence of collision between the first connecting rod 221 and the first limit member 61. Similarly, when the sensing slot 7a of the retraction sensor 72 senses the block 2211, the motor 21 can be controlled to be closed by the controller to reduce the occurrence of collision between the first connecting rod 221 and the second limit member 62, which has high safety.

[0066] In one embodiment, please refer to Figure 2 and Figure 3The vertical plate 6 is constructed with a frame 63 protruding from the surface of the vertical plate 6. The frame 63 is arranged around the rotation path of at least one end of the first connecting rod 221. The parts on both sides of the frame 63 along the radial direction of the output shaft extend toward the direction close to the output shaft to form a first limit member 61 and a second limit member 62. The protective cover 4 is covered on the frame 63 and forms a storage space 63a with the frame 63. The circuit board 3 is located in the storage space 63a, and the first connecting rod 221 is at least partially accommodated in the storage space 63a.

[0067] For example, one end of the frame 63 can be connected to the vertical plate 6, and the other end of the frame 63 can extend along the thickness direction of the vertical plate 6 toward the direction close to the fan. The protective cover 4 is provided on the extended end of the frame 63 to jointly define a storage space 63a. The circuit board 3 and the position sensor 7 are both located in the storage space 63a. Portions of the frame 63 on both sides along the radial direction of the output shaft extend toward the output shaft to form a first stopper 61 and a second stopper 62. A notch 63b is formed between the first stopper 61 and the second stopper 62, which communicates with the storage space 63a. The end of the first connecting rod 221 having the stopper 2211 can be located in the storage space 63a. The other end of the first connecting rod 221 along its length extends through the notch 63b and is hingedly connected to the second connecting rod 222.

[0068] In this way, by setting a frame 63 and cooperating with the protective cover 4, on the one hand, the parts located in the storage space 63a can be protected to reduce the impact of dust and other foreign matter entering the storage space 63a and affecting the function of the parts; on the other hand, due to the obstruction of the protective cover 4, the gas discharged from the air outlet can be reduced from entering the storage space 63a. In this way, not only can the air outlet path be optimized and the obstruction of the air outlet path be reduced, but the whistling sound caused by the air blowing into the storage space 63a can also be reduced.

[0069] It is understandable that, due to the presence of the frame 63, the storage space 63a is roughly an annular cavity, and the gap 63b is equivalent to a whistle. In this way, when the air blows into the storage space 63a, a whistle sound may be caused.

[0070] In one embodiment, the protective cover 4 is detachably connected to the frame 63. In this way, the protective cover 4 and the frame 63 are detachably connected, which facilitates the removal and installation of the protective cover 4 and helps with inspection and maintenance.

[0071] In one embodiment, the cleaning device 100 includes a fastener that passes through the protective cover 4 and the frame 63. For example, the first stopper 61 and the portion of the frame 63 near the second stopper 62 can each be formed with a first mounting hole, and a second mounting hole can be formed at a corresponding position on the protective cover 4. The fastener can be passed through the first mounting hole and the second mounting hole. In this way, the connection strength between the protective cover 4 and the frame 63 can be improved, and the protective cover 4 can be reduced from falling off.

[0072] For example, in one embodiment, the fastener may be a bolt or a screw.

[0073] For example, in one embodiment, the frame 63 and the protective cover 4 can be connected by snap fastening.

[0074] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, and improvements that fall within the spirit and principles of the present application are intended to be within the scope of protection of the present application.
