Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and in particular to a roller brush alignment structure and a cleaning equipment. Background Art

[0002] In related art, the motor of a cleaning device can drive the cleaning component via a drive shaft. The drive shaft and cleaning component are connected by a stopper structure that restricts their relative rotation, allowing them to rotate synchronously. However, during the insertion of the cleaning component into the drive shaft, the cleaning component must be aligned with the drive shaft in a predetermined position to ensure successful insertion, which reduces the efficiency of the insertion. Summary of the Invention

[0003] The invention provides a roller brush alignment structure and cleaning equipment.

[0004] The roller brush alignment structure of the embodiment of the present invention includes a drive shaft and a cleaning component, which includes a roller, a connector, and an elastic mechanism. The connector is movable relative to the roller along its axial direction and rotates synchronously with the roller, while the elastic mechanism connects the roller and the connector. The elastic mechanism is configured to drive the connector into engagement with the drive shaft when the drive shaft rotates to shift the drive shaft and connector from a misaligned state to an aligned state.

[0005] The roller brush alignment structure of the present invention utilizes an elastic mechanism to drive the connector to move, allowing the drive shaft and cleaning component to be connected even when the drive shaft and connector are misaligned. Furthermore, after the drive shaft and cleaning component are connected, the connector and drive shaft can shift from a misaligned state to an aligned state as the drive shaft rotates. This eliminates the need to adjust the cleaning component to a predetermined position relative to the drive shaft during connection, improving the efficiency of the roller brush alignment structure.

[0006] In some embodiments, the elastic mechanism is used to store force when the drive shaft and the connecting member are in a misaligned state and the drive shaft abuts against the connecting member to move the connecting member along a first moving direction relative to the roller, and when the drive shaft rotates relative to the connecting member and is in an aligned state, release the stored force to move the connecting member along a second moving direction relative to the roller, so that the drive shaft and the connecting member are plugged into each other, and then the drive shaft and the connecting member move synchronously, and the first moving direction is opposite to the second moving direction.

[0007] In this way, when the elastic mechanism accumulates force, it drives the connecting member to move in the first direction while misaligned with the drive shaft, allowing the drive shaft and the cleaning member to be plugged together even when the drive shaft and the cleaning member are misaligned. After the drive shaft and the cleaning member are plugged together, the drive shaft rotates so that the drive shaft and the connecting member are aligned, and the elastic mechanism releases the accumulated force to drive the connecting member to move in the second direction, allowing the drive shaft and the connecting member to be plugged together.

[0008] In some embodiments, the driving shaft is formed with a first engaging structure, the connecting member is formed with a second engaging structure, and the first engaging structure is engaged and connected with the second engaging structure.

[0009] In this way, the first engaging structure and the second engaging structure are engaged and connected to limit the movement of the drive shaft relative to the connecting member, so that the plug-in connection between the drive shaft and the connecting member is more stable.

[0010] In some embodiments, the drive shaft includes a central axis, the first engaging structure includes a locking groove formed on the side of the central axis; the connecting member is formed with an insertion hole, the second engaging structure includes a limit block formed on the side of the insertion hole, and the limit block is engaged in the locking groove.

[0011] In this way, the first engaging structure and the second engaging structure are engaged with the engaging groove via the limiting block, thereby limiting the movement of the drive shaft relative to the connecting member, making the connection between the drive shaft and the connecting member more stable.

[0012] In some embodiments, there are multiple positioning slots, which are arranged circumferentially along the central axis; there are multiple limiting blocks, which correspond one-to-one to the positioning slots.

[0013] In this way, the plurality of latching grooves are arranged along the circumference of the central axis, so that when the limiting blocks are engaged and connected with the latching grooves in a one-to-one correspondence, the driving shaft and the connecting member are evenly stressed.

[0014] In some embodiments, along the second moving direction, the width of the positioning groove tends to decrease.

[0015] In this way, the locking groove is easily engaged with the limiting block, so that the driving shaft is easily plugged into the connecting piece.

[0016] In some embodiments, along the circumference of the plug-in hole, the limit block includes a first surface and a second surface opposite to each other. When the drive shaft rotates along the first rotation direction, the first surface of the limit block engages with the first side surface of the locking groove to enable the drive shaft to drive the connecting member to rotate; when the drive shaft rotates along the second rotation direction, the second surface of the limit block cooperates with the second side surface of the locking groove to enable the drive shaft to drive the connecting member to move along the first moving direction and enable the elastic mechanism to accumulate force. The first rotation direction is opposite to the second rotation direction.

[0017] In this way, the driving shaft and the connecting member can be restricted from rotating in a single direction by the different settings of the first surface and the second surface of the limiting block.

[0018] In some embodiments, the second surface of the limiting block extends from a side of the limiting block away from the driving shaft along the second rotation direction and the second movement direction.

[0019] In this way, the second surface extends along a specific direction so that when the drive shaft rotates along the second rotation direction, the driving connection member moves along the first movement direction, so that the limit block and the limit groove are misaligned, limiting the drive shaft from rotating along the second rotation direction.

[0020] In some embodiments, the elastic mechanism includes a mounting seat and an elastic member, the mounting seat is fixed in the roller, the mounting seat is formed with a mounting hole, the connecting member is accommodated in the mounting hole, and the elastic member connects the mounting seat and the connecting member.

[0021] In this way, the elastic member is elastically deformed to drive the connecting member to move relative to the mounting seat and the roller shaft, so that the roller brush alignment structure can still complete the plug-in when the connecting member is misaligned with the drive shaft.

[0022] The cleaning device according to the embodiment of the present invention includes the roller brush alignment structure according to any one of the above embodiments and a motor connected to the drive shaft.

[0023] In this way, the motor can provide power to the drive shaft, so that the drive shaft can drive the cleaning component to move and complete the cleaning work of the cleaning equipment.

[0050] See also Figure 1-Figure 4 The roller brush alignment structure 200 according to an embodiment of the present invention is used in a cleaning device 1000. The roller brush alignment structure 200 includes a drive shaft 132 and a cleaning component 20. The cleaning component 20 includes a roller 21, a connector 22, and an elastic mechanism 23. The connector 22 is movable relative to the roller 21 along the axial direction of the roller 21 and is capable of rotating synchronously with the roller 21. The elastic mechanism 23 connects the roller 21 and the connector 22. The elastic mechanism 23 is used to drive the connector 22 to engage with the drive shaft 132 when the drive shaft 132 rotates to switch the drive shaft 132 and the connector 22 from a misaligned state to an aligned state.

[0051] The roller brush alignment structure 200 of the embodiment of the present invention drives the connector 22 to move via the elastic mechanism 23, allowing the drive shaft 132 and the cleaning component 20 to be plugged in even when the drive shaft 132 and the connector 22 are misaligned. Furthermore, after the drive shaft 132 and the cleaning component 20 are plugged in, the connector 22 and the drive shaft 132 can switch from a misaligned state to an aligned state as the drive shaft 132 rotates. Therefore, during the plugging process of the cleaning component 20 and the drive shaft 132, there is no need to adjust the cleaning component 20 to align with the drive shaft 132 in a predetermined position, thereby improving the plugging efficiency of the roller brush alignment structure 200.

[0052] Specifically, the cleaning device 1000 can be a cleaning robot 100, such as a robot vacuum or mopping robot, capable of electrically driving the cleaning component 20 to complete cleaning operations. The cleaning device 1000 can also be a cleaning tool such as a vacuum cleaner or lint remover, which can be driven electrically or manually. The cleaning component 20 is rotatably mounted on the cleaning device 1000, rotating relative to the cleaning device 100 and moving relative to the work surface with the cleaning device 100, thereby cleaning the work surface.

[0053] In the cleaning component 20, the roller 21, the connecting member 22 and the elastic mechanism 23 can be coaxial, and the elastic mechanism 23 can drive the connecting member 22 to move axially relative to the roller 21. The connecting member 22 and the elastic mechanism 23 can be arranged at one end of the roller 21 in the axial direction and accommodated inside the roller 21.

[0054] During the insertion and connection process between the cleaning component 20 and the drive shaft 132, the drive shaft 132 and the connector 22 can be misaligned and abut against each other. Driven by the abutment and push of the drive shaft 132, the connector 22 moves relative to the roller 21, providing space for the drive shaft 132 to be inserted into the roller 21. After the drive shaft 132 and the roller 21 are inserted, the drive shaft 132 rotates relative to the connector 22, and the drive shaft 132 and the connector 22 switch from the misaligned state to the aligned state. The elastic mechanism 23 pushes the connector 22 in the opposite direction and inserts it into the drive shaft 132.

[0055] See also Figure 2-Figure 4 In some embodiments, the elastic mechanism 23 is used to store force when the drive shaft 132 and the connecting member 22 are in a misaligned state and the drive shaft 132 abuts against the connecting member 22 to move the connecting member 22 relative to the roller 21 along the first moving direction a, and when the drive shaft 132 rotates relative to the connecting member 22 and is in an aligned state, release the stored force to move the connecting member 22 relative to the roller 21 along the second moving direction b, so that the drive shaft 132 is plugged into the connecting member 22, and then the drive shaft 132 and the connecting member 22 move synchronously, and the first moving direction a is opposite to the second moving direction b.

[0056] In this way, when the elastic mechanism 23 accumulates force, it drives the connecting member 22 to move in the first movement direction a while being misaligned with the drive shaft 132, so that the drive shaft 132 and the cleaning component 20 can be plugged together even though the drive shaft 132 and the connecting member 22 are misaligned. After the drive shaft 132 and the cleaning component 20 are plugged together, the drive shaft 132 rotates so that the drive shaft 132 and the connecting member 22 are switched to an aligned state. The elastic mechanism 23 releases the accumulated force and drives the connecting member 22 to move in the second movement direction b, so that the drive shaft 132 and the connecting member 22 are plugged together and maintain a synchronous movement state.

[0057] Specifically, the axial direction of the drive shaft 132 can be set to be located in the axial extension direction of the roller 21. The first moving direction a can be the direction from the drive shaft 132 to the elastic mechanism 23 along the axial direction of the roller 21, and the second moving direction b can be the direction from the elastic mechanism 23 to the drive shaft 132 along the axial direction of the roller 21.

[0058] When assembling the roller brush alignment structure 200, the cleaning component 20 moves relative to the drive shaft 132 along the second movement direction b, so that the drive shaft 132 abuts the connecting member 22. When the drive shaft 132 abuts the connecting member 22, the limiting structures of the drive shaft 132 and the connecting member 22 are misaligned and not engaged, and the roller 21 in the cleaning component 20 continues to move relative to the drive shaft 132 along the second movement direction b. Then, the drive shaft 132 pushes the connecting member 22 to squeeze the elastic mechanism 23, and the elastic mechanism 23 drives the connecting member 22 to move relative to the roller 21 along the first movement direction a, making room for the drive shaft 132. Therefore, even when the drive shaft 132 and the connecting member 22 are misaligned, the roller 21 is still plugged into the drive shaft 132.

[0059] Furthermore, when the drive shaft 132 and the connecting member 22 are misaligned, the roller 21 and the drive shaft 132 are plugged together, the drive shaft 132 abuts against the connecting member 22, and the elastic mechanism 23 contracts to store force. The drive shaft 132 can rotate relative to the cleaning component 20. During the rotation of the drive shaft 132, the pressure of the drive shaft 132 on the connecting member 22 and the elastic mechanism 23 in the axial direction is dispersed, allowing the elastic mechanism 23 to release the stored force, pushing the connecting member 22 to move relative to the drive shaft 132 and the roller 21 in the second movement direction b. When the drive shaft 132 rotates to a position aligned with the connecting member 22, the connecting member 22 and the drive shaft 132 are pushed to complete the plugging.

[0060] See also Figure 4 、 Figure 6 and Figure 7 In some embodiments, the driving shaft 132 is formed with a first engaging structure 201 , and the connecting member 22 is formed with a second engaging structure 202 , and the first engaging structure 201 is engaged with the second engaging structure 202 .

[0061] In this way, the first engaging structure 201 and the second engaging structure 202 are engaged with each other to limit the movement of the driving shaft 132 relative to the connecting member 22 , so that the connection between the driving shaft 132 and the connecting member 22 is more stable.

[0062] Specifically, one of the first engaging structure 201 and the second engaging structure 202 is provided with a locking groove 221, and the other is provided with a limiting block 222. The limiting block 222 can be inserted into the limiting groove to engage the first engaging structure 201 with the second engaging structure 202. The first engaging structure 201 and the second engaging structure 202 are engaged and connected to limit the relative movement of the drive shaft 132 and the connecting member 22. Therefore, when the drive shaft 132 rotates, the drive shaft 132 and other components can rotate synchronously with the drive shaft 132, and the relative displacement between the cleaning component 20 and the drive shaft 132 in the axial or radial direction is reduced, thereby maintaining the stability of the rotation of the roller brush alignment structure 200.

[0063] See also Figure 6and Figure 7 In some embodiments, the drive shaft 132 includes a central shaft 133, and the first engaging structure 201 includes a locking groove 221 formed on the side of the central shaft 133; the connecting member 22 is formed with an insertion hole 2201, and the second engaging structure 202 includes a limiting block 222 formed on the side of the insertion hole 2201, and the limiting block 222 is engaged in the locking groove 221.

[0064] In this way, the first engaging structure 201 and the second engaging structure 202 are engaged with the engaging groove 221 through the limiting block 222, limiting the movement of the driving shaft 132 relative to the connecting member 22, making the connection between the driving shaft 132 and the connecting member 22 more stable.

[0065] Specific, combined Figure 2 and Figure 4 The drive shaft 132 can be configured to have a smaller diameter than the insertion hole 2201, allowing the drive shaft 132 to be inserted into the insertion hole 2201. The retaining groove 221 can extend axially along the outer circumference of the central shaft 133, and the stopper 222 can extend axially along the inner circumference of the insertion hole 2201. The drive shaft 132 abuts against the connector 22 and is coaxial with the connector 22. The connector 22 moves relative to the drive shaft 132 in the second movement direction b, causing the stopper 222 to slide into the retaining groove 221 and engage with the retaining groove 221.

[0066] When the limiting block 222 is aligned with the limiting groove along the second moving direction b, the drive shaft 132 and the connecting member 22 are in alignment, which facilitates the limiting block 222 to be inserted into the locking groove 221 and complete the engagement.

[0067] See also Figure 5-Figure 7 In some embodiments, there are multiple positioning slots 221 , which are arranged circumferentially along the central axis 133 , and there are multiple limiting blocks 222 , which correspond one-to-one to the positioning slots 221 .

[0068] In this way, the plurality of locking grooves 221 are arranged along the circumference of the central axis 133 , so that when the limiting blocks 222 are engaged with the locking grooves 221 in a one-to-one correspondence, the driving shaft 132 and the connecting member 22 are evenly stressed.

[0069] Specifically, when the drive shaft 132 rotates, the locking groove 221 engages with the stop block 222. The connecting member 22 receives a force from the drive shaft 132 at the interface between the locking groove 221 and the stop block 222, causing it to rotate synchronously with the drive shaft 132 under the drive shaft 132. During the synchronous rotation of the connecting member 22 and the drive shaft 132, the drive shaft 132 also receives a counterforce from the connecting member 22 at the interface between the locking groove 221 and the stop block 222. The one-to-one engagement of multiple locking grooves 221 with multiple stop blocks 222 enhances the stability of the connection between the drive shaft 132 and the connecting member 22.

[0070] Furthermore, the plurality of retaining grooves 221 are substantially evenly distributed along the circumferential direction of the central axis 133 on the side surface of the center circumference. For example, there are three retaining grooves 221, and the three retaining grooves 221 can be centrally symmetrical with respect to the axis of the central axis 133. The plurality of limiting blocks 222 are distributed on the outer circumferential surface of the connecting member 22 in a one-to-one correspondence with the retaining grooves 221 and are substantially evenly distributed along the circumference of the connecting member 22. As a result, the force applied to the drive shaft 132 and the connecting member 22 along the circumferential direction during synchronous rotation is relatively uniform, which helps reduce wear and tear and increase the service life of the drive shaft 132 and the connecting member 22.

[0071] See also Figure 6 In some embodiments, along the second moving direction b, the width d of the positioning groove 221 tends to decrease.

[0072] In this way, the locking groove 221 is easily engaged with the limiting block 222 , so that the driving shaft 132 is easily plugged into the connecting member 22 .

[0073] Specifically, during the process of plugging the cleaning component 20 into the driving shaft 132, the cleaning component 20 moves relative to the driving shaft 132 along the second moving direction b. The width d of the positioning groove 221 tends to decrease along the second moving direction b. During the movement of the cleaning component 20, the width d of the positioning groove 221 at the position where the connecting member 22 first contacts is the largest, and the limiting block 222 can easily enter the positioning groove 221. During the process of the connecting member 22 moving along the second direction and the limiting block 222 engaging with the positioning groove 221, the width d of the positioning groove 221 can gradually decrease, so that the positioning groove 221 can easily limit the relative movement of the limiting block 222 and the locking connection is firm. Figure 2 and Figure 7 The limiting block 222 cooperates with the locking groove 221, and the width of the limiting block 222 can show a decreasing trend along the second moving direction b.

[0074] Please refer again Figure 6 and Figure 7In some embodiments, along the circumference of the plug hole 2201, the limit block 222 includes a first surface 2221 and a second surface 2222 opposite to each other. When the drive shaft 132 rotates along the first rotation direction w, the first surface 2221 of the limit block 222 engages with the first side surface 2211 of the locking groove 221, so that the drive shaft 132 drives the connecting member 22 to rotate; when the drive shaft 132 rotates along the second rotation direction v, the second surface 2222 of the limit block 222 cooperates with the second side surface 2212 of the locking groove 221, so that the drive shaft 132 drives the connecting member 22 to move along the first moving direction a and causes the elastic mechanism 23 to accumulate force. The first rotation direction w is opposite to the second rotation direction v.

[0075] In this way, the driving shaft 132 and the connecting member 22 can be restricted from rotating in a single direction by the different arrangements of the first surface 2221 and the second surface 2222 of the limiting block 222 .

[0076] Specific, combined Figure 4 and Figure 5 The first surface 2221 can extend generally along the second movement direction b, with the first side surface 2211 extending in a direction that aligns with the first surface 2221. When the drive shaft 132 rotates in the first rotational direction w, the connector 22 receives a driving force along the first rotational direction w on the first surface 2221, causing it to also rotate in the second rotational direction v. The second surface 2222 can be connected to the first surface 2221 on the side of the connector 22 facing the drive shaft 132. Along the circumference of the connector 22, the second surface 2222 faces away from the first surface 2221, and the distance between the second surface 2222 and the first surface 2221 increases along the first movement direction a. The first side surface 2211 and the second side surface 2212 can be arranged in a substantially mirror-image configuration. When the drive shaft 132 rotates in the second direction, the second side surface 2212 cooperates with the second side surface 2222. The connecting member 22 is subjected to a force in the first movement direction a on the second side surface 2222. Consequently, the connecting member 22 moves in the first movement direction a and pushes the elastic mechanism 23 to contract and accumulate force in the first movement direction a. This hinders the rotation of the connecting member 22 along the drive shaft 132 in the second rotation direction v. The connecting member 22 and the cleaning component 20 as a whole are restricted by the cooperation between the second side surface 2222 and the second side surface 2212, and can rotate in the first rotation direction w but cannot rotate in the second rotation direction v.

[0077] Please continue reading Figure 6 and Figure 7 In some embodiments, the second surface 2222 of the limiting block 222 extends from a side of the limiting block 222 away from the driving shaft 132 along the second rotation direction v and the second movement direction b.

[0078] In this way, the second surface 2222 extends along a specific direction so that when the drive shaft 132 rotates along the second rotation direction v, the driving connector 22 moves along the first movement direction a, so that the limit block 222 and the limit groove are misaligned, making it difficult for the drive shaft 132 to continue to rotate along the second rotation direction v.

[0079] Specifically, the second surface 2222 extends in a spiral shape along the second rotation direction v and the second movement direction b on the inner circumference of the connecting member 22. Figure 4 When the drive shaft 132 rotates in the second rotation direction v, the second side surface 2212 overlaps the second surface 2222, and the drive shaft 132 tends to move out of the insertion hole 2201 along the extension direction of the second surface 2222. Because the drive shaft 132 and the roller 21 are fixedly connected, the connector 22 tends to move in a direction opposite to the extension direction of the second surface 2222 relative to the drive shaft 132 and the roller 21. Consequently, when the drive shaft 132 rotates in the second rotation direction v, the connector 22 tends to move in the first movement direction a, disengaging from the engagement with the drive shaft 132. This forces the elastic mechanism 23 to contract and accumulate force, thereby restricting the drive shaft 132 from further rotation in the second rotation direction v.

[0080] See also Figure 2 and Figure 4 In some embodiments, the elastic mechanism 23 includes a mounting seat 231 and an elastic member 232. The mounting seat 231 is fixed in the roller 21. The mounting seat 231 is formed with a mounting hole 2311. The connecting member 22 is accommodated in the mounting hole 2311. The elastic member 232 connects the mounting seat 231 and the connecting member 22.

[0081] In this way, when the elastic member 232 is elastically deformed, it drives the connecting member 22 to move relative to the mounting seat 231 and the roller 21, so that the roller brush alignment structure 200 can still complete the insertion when the connecting member 22 and the driving shaft 132 are misaligned.

[0082] Specifically, the mounting seat 231 and the mounting hole 2311 are coaxial with the roller 21. The connector 22 is disposed in the mounting hole 2311 and is axially movable relative to the mounting seat 231. The elastic member 232 can be an elastic element such as a spring. When in a contracted state, it stores force and then relaxes and extends to release the stored force. The elastic member 232 is disposed axially along the roller 21. When the elastic member 232 contracts and stores force, it drives the connector 22 in a first movement direction a. When the elastic member 232 releases the stored force and extends, it drives the connector 22 in a second movement direction b.

[0083] Please refer again Figure 1 and Figure 2 In some embodiments, bristles 134 are provided on the outer side of the roller 21 .

[0084] In this way, when the roller 21 is driven by the driving shaft 132 to rotate, the roller 21 can scrub external objects through the bristles 134 .

[0085] Specifically, the outer side of the roller 21 is provided with bristles 134 to form a roller brush 131. The bristles 134 can contact the working surface, and when the driving shaft 132 drives the roller 21 to rotate, the roller brush 131 can roll on the working surface. During the rolling process, the bristles 134 can clean the stains on the working surface.

[0086] In some embodiments, a rag, glue, etc. can also be provided on the outer side of the roller 21 to form a roller, a sticky cylinder, etc., which can also be used for cleaning.

[0087] See also Figures 8-10 The cleaning device 1000 according to the embodiment of the present invention includes the roller brush alignment structure 200 according to any of the above embodiments and a motor 300 connected to the drive shaft 132.

[0088] In this way, the motor 300 can provide power to the driving shaft 132 , so that the driving shaft 132 can drive the cleaning component 20 to move, thereby completing the cleaning work of the cleaning device 1000 .

[0089] Specific, combined Figure 1 and Figure 10 Drive shaft 132 rotates under the drive of motor 300, driving cleaning component 20 to rotate. In cleaning device 1000, cleaning component 20 is a shaft-type cleaning device, such as a roller brush 131, a roller, or a sticking drum. During rotation, cleaning component 20 contacts the work surface to be cleaned, thereby sweeping or adhering to dust and particles on the work surface, and also cleaning stains such as dirty water and hair from the work surface. The work surface to be cleaned can be a floor, wall, tabletop, architectural glass, carpet, sofa, clothing, etc.

[0090] See also Figure 9 and Figure 10 In some embodiments, the cleaning device 1000 may be a cleaning robot 100 . The cleaning robot 100 includes a body 10 . The body 10 includes a shell. The motor 300 is disposed on the shell.

[0091] In this way, the cleaning component 20 can be used for the cleaning assembly 60 of the cleaning robot 100 , so that the cleaning assembly 60 does not need to be adjusted to a predetermined position when inserted into the body 10 , thereby improving the installation efficiency of the cleaning assembly 60 .

[0092] Specifically, the cleaning robot 100 can be a floor scrubber robot, a floor sweeping robot, a sweeping and mopping robot, etc. The body 10 is the main part of the cleaning robot 100, and the shell can constitute the general outline of the body 10. The body 10 can walk on the working surface, and the cleaning working surface can be a floor or carpet of any material, such as a wooden floor, a tile floor, etc. Figure 2 The motor 300 can drive the drive shaft 132 to rotate relative to the housing, thereby driving the connection member 22 and the roller 21 to rotate. The cleaning component 20 can be disposed on the side of the housing facing the work surface. The outer peripheral surface of the roller 21 is covered with bristles 134 to form a roller brush 131, which serves as the cleaning member 13 of the cleaning robot 100. As the roller 21 rotates, the roller brush 131 cleans the work surface.

[0093] See also Figure 10-13 The cleaning robot 100 of the embodiment of the present application includes a body 10 and a cleaning component 60, the body 10 includes a shell 62, and the shell 62 forms an installation cavity 621; the cleaning component 60 includes a bracket 61 and a cleaning member 13 installed on the bracket 61, the bracket 61 is slidably arranged in the installation cavity 621, and the bracket 61 is detachably connected to the shell 62.

[0094] In the cleaning robot 100 of the embodiment of the present application, the bracket 61 is slidably arranged in the installation cavity 621, and the bracket 61 is detachably connected to the shell 62, so that the cleaning member 13 can be slidably removed from the shell 62 of the body 10 following the bracket 61 for easy cleaning and convenient operation.

[0095] Specific, combined Figure 8 and Figure 10 In some embodiments, the body 10 includes a sensing device 11, a control unit, and a drive wheel 12. The sensing device 11 is used to monitor the surrounding environment, and the control unit is used for accurate distance measurement and active obstacle avoidance, as well as controlling the motion trajectory of the drive wheel 12. The sensing device 11 can be a collision sensor, a proximity sensor, a visual sensor, etc. The functional components of the cleaning robot 100, such as the sensing device 11, the drive wheel 12, and the cleaning assembly 60, can be mounted on the housing 62. The mounting cavity 621 can be formed on the side of the housing 62 facing the work surface.

[0096] When the forward direction of the cleaning robot 100 is set to the front, the driving wheel 12 is arranged behind the cleaning part 13. The cleaning part 13 can clean the dirt, water stains, etc. on the ground in front of the driving wheel 12 to prevent dust and water stains from affecting the friction between the driving wheel 12 and the ground, thereby protecting the driving wheel 12 and improving the movement ability of the body 10.

[0097] The cleaning assembly 60 can be partially housed within the mounting cavity 621, allowing the cleaning member 13 to contact the work surface. The cleaning member 13 can include a rag, a roller brush 131, a drum, etc., and can wipe or scrub the work surface while the machine body 10 is in motion. The bracket 61 can partially cover the cleaning member 13 and form a portion of the circumference of the machine body 10.

[0098] In one embodiment, Figure 11 As shown, the housing 10 is generally disc-shaped, with a mounting cavity 621 communicating with an opening 620 on the circumference of the housing 62 and extending along a straight path toward the other side of the circumference of the housing 62. The bracket 61 can be slidably inserted into the mounting cavity 621 from the opening 620 along the direction in which the mounting cavity 621 extends, thereby mounting the cleaning assembly 60 to the bottom of the housing 62. The bracket 61 can also be slidably withdrawn from the mounting cavity 621 along the direction in which the mounting cavity 621 extends, thereby removing the cleaning assembly 60 from the bottom of the housing 62.

[0099] See also Figure 10-12 In some embodiments, the cleaning robot 100 includes a locking member 622 movably disposed on the shell 62. The locking member 622 can be partially located in the mounting cavity 621 or outside the mounting cavity 621. When the locking member 622 is partially located in the mounting cavity 621, the locking member 622 can engage with the bracket 61 to lock the bracket 61 on the shell 62.

[0100] In this way, the bracket 61 can be engaged with the shell 62 through the locking piece 622, which facilitates the disassembly and assembly of the cleaning component 60.

[0101] Specifically, the locking member 622 can be located on the sliding path of the bracket 61 entering and exiting the mounting cavity 621. During the process of the bracket 61 sliding into the mounting cavity 621, the bracket 61 can be in sliding contact with the locking member 622. Due to the sliding of the bracket 61, the locking member 622 is subjected to a certain pressure applied by the bracket 61 and exits the mounting cavity 621. When the bracket 61 slides to a certain position, the locking member 622 partially extends into the mounting cavity 621 and engages with the bracket 61, thereby locking the bracket 61 in a fixed position on the housing 62. During the process of the bracket 61 sliding out of the mounting cavity 621, the locking member 622 is located outside the mounting cavity 621.

[0102] See also Figure 14 In some embodiments, the locking member 622 includes a first arm 6221 and a second arm 6222 connected to the first arm 6221. The connection between the first arm 6221 and the second arm 6222 is rotatably connected to the shell 62. During the rotation of the locking member 622, the second arm 6222 can be partially located in the installation cavity 621 or outside the installation cavity 621. When the second arm 6222 is partially located in the installation cavity 621, the second arm 6222 can engage with the bracket 61.

[0103] In this way, the locking member 622 is engaged with the cleaning assembly 60 through the second arm 6222 , and the locking member 622 is engaged with or disengaged from the bracket 61 by rotating the connection between the first arm 6221 and the second arm 6222 .

[0104] Specifically, a rotation axis 6223 may be formed at the connection between the first arm 6221 and the second arm 6222, and both the first arm 6221 and the second arm 6222 may rotate relative to the housing 62 about the rotation axis 6223. During the rotation of the locking member 622 relative to the housing 62, the first arm 6221 and the second arm 6222 may remain relatively fixed. The end of the second arm 6222 away from the rotation axis 6223 may be located in the mounting cavity 621.

[0105] The second arm 6222 is formed with an inclined surface 6224 that is inclined relative to the axial direction of the rotation axis 6223. The inclined surface 6224 can be configured so that the height of the end of the second arm 6222 located within the mounting cavity 621 gradually increases as the bracket 61 slides into the mounting cavity 621. In this way, as the bracket 61 slides into the mounting cavity 621, the bracket 61 presses against the end of the second arm 6222 along the inclined surface 6224, causing the second arm 6222 to rotate about the rotation axis 6223 to a position outside the mounting cavity 621.

[0106] See also Figure 14-16 In some embodiments, the cleaning robot 100 includes a driving component 70 movably mounted on the housing 62. The driving component 70 is connected to the first arm 6221. When the driving component 70 is pressed, the first arm 6221 drives the second arm 6222 to rotate and move out of the mounting cavity 621. In some embodiments, the driving component 70 is located at the top of the body 10.

[0107] Thus, the user can control the locking member 622 to disengage from the bracket 61 by pressing the driving member 70, so that the cleaning assembly 60 can slide out of the mounting cavity 621, which is easy to operate. The driving member 70 is located at the top of the body 10, making it easy for the user to press the driving member 70.

[0108] Specifically, the driving component 70 can be a button, a slider, an electronic display, a touch button, etc., and can control the locking member 622 through electronic or mechanical control. For example, if the driving component 70 is a button, the driving component 70 can be connected to the end of the first arm 6221 away from the rotation axis 6223. When the driving component 70 is pressed, the direction of movement of the driving component 70 forms a certain angle with the direction of the first arm 6221, so that the movement of the driving component 70 can drive the first arm 6221 to rotate about the rotation axis 6223. The second arm 6222 is fixedly connected to the first arm 6221, and when the driving component 70 is pressed, the second arm 6222 rotates simultaneously with the first arm 6221.

[0109] The driving component 70 may also be electrically connected to the first arm 6221 . For example, the driving component 70 is a touch button embedded in the top surface of the body 10 .

[0110] In this application, the side of the body 10 facing the working surface is defined as the bottom, and the side facing away from the working surface and opposite to the bottom is defined as the top. Obviously, the driving component 70 is located at the top of the body 10 for easy user operation. When the driving component 70 is pressed, it moves toward the bottom, or in other words, the driving component 70 moves downward, thereby driving the end of the first arm 6221 away from the rotating shaft 6223 to rotate downward. The second arm 6222 and the first arm 6221 can form a certain angle, so that when the first arm 6221 is driven by the driving component 70 to rotate downward, the second arm 6222 rotates with the first arm 6221, and the end of the second arm 6222 away from the rotating shaft 6223 moves backward to the outside of the mounting cavity 621.

[0111] In some embodiments, the driving component 70 may also be located at the bottom or side of the body 10 .

[0112] Please continue reading Figure 15 and Figure 16 In some embodiments, the cleaning robot 100 includes a first elastic member 80, which connects the shell 62 and the second arm 6222. When the bracket 61 slides into the installation cavity 621, the bracket 61 pushes the second arm 6222 to move out of the installation cavity 621 and causes the first elastic member 80 to store force. When the bracket 61 is at a predetermined position in the installation cavity 621, the first elastic member 80 releases the stored force to push the second arm 6222 partially into the installation cavity 621 and engage with the bracket 61.

[0113] In this way, the first elastic member 80 pushes the second arm 6222 to move partially in and out of the mounting cavity 621 as the bracket 61 slides, so that the locking member 622 will not hinder the process of the bracket 61 sliding into the mounting cavity 621, and the locking member 622 can be automatically reset to the mounting cavity 621 under the elastic force of the first elastic member 80 after being squeezed out of the mounting cavity 621 by the sliding bracket 61.

[0114] Specifically, the first elastic member 80 is provided on the shell 62, connecting the side of the second arm 6222 away from the installation cavity 621. The first elastic member 80 can be a spring, one end of the spring is bonded to the second arm 6222, and the other end is partially wrapped and fixed by the kit 81. In the process of the bracket 61 sliding into the installation cavity 621, the bracket 61 pushes the second arm 6222 to move out of the installation cavity 621 and compresses the spring. The bracket 61 is in a predetermined position in the installation cavity 621, which can be that part of the bracket 61 is consistent with the circumference of the shell 62, and the cleaning component 60 is in a predetermined installation position. At this time, the spring is extended, pushing the second arm 6222 to engage with the bracket 61. The kit 81 can limit the direction of contraction and extension of the spring, and thereby control the direction of the pushing force of the first elastic member 80 on the second arm 6222.

[0115] See also Figure 15-17 In some embodiments, the bracket 61 is formed with a locking groove 615 . When the locking member 622 is engaged with the locking groove 615 , the locking member 622 limits the bracket 61 from sliding relative to the housing 62 .

[0116] In this way, by engaging the locking groove 615 with the locking piece 622 , the connection strength of the bracket 61 in the installation cavity 621 can be strengthened, the sliding of the bracket 61 relative to the shell 62 can be restricted, and the stability of the bracket 61 installed in the shell 62 can be increased.

[0117] Specifically, the cross-sectional shape of the locking groove 615 can mate with the contour of the portion of the second arm 6222 located within the mounting cavity 621. The bottom surface of the locking groove 615 can be inclined relative to the surface of the bracket 61 where the locking groove 615 is located, and mate with the inclined surface 6224 of the second arm 6222. The locking groove 615 can be a sunken groove, so that when the bracket 61 slides so that the locking groove 615 is aligned with the locking member 622, the bracket 61 temporarily disengages from the locking member 622, releasing the pressure on the first elastic member 80. The first elastic member 80 then releases its stored force, pushing the second arm 6222 partially into the mounting cavity 621 and engaging with the locking groove 615.

[0118] See also Figure 11 and Figure 18 In some embodiments, the cleaning robot includes a pop-up assembly 623 mounted on the housing 62 , which is connected to the bracket 61 and partially pops the bracket 61 out of the mounting cavity 621 when the locking member 622 is disengaged from the bracket 61 .

[0119] In this way, the bracket 61 can be partially ejected from the mounting cavity 621 by the ejection assembly 623 when the driving component 70 is pressed, so as to facilitate the sliding removal of the bracket 61 from the housing 62 .

[0120] Specific, combined Figure 10The ejection assembly 623 can be arranged along the sliding path of the bracket 61. The bracket 61 is installed in the installation cavity 621, and a portion of the bracket 61 forms the circumference of the housing 62. The ejection assembly 623 is in a power-storage state. When the driving component 70 is pressed, the locking member 622 moves out of the installation cavity 621, disengaging from the bracket 61. The ejection assembly 623 releases the power stored, pushing the bracket 61 partially out of the installation cavity 621, making it easy to hold the portion of the bracket 61 that has exited the installation cavity 621 to completely remove the cleaning assembly 60 from the installation cavity 621.

[0121] Please continue reading Figure 18 In some embodiments, the pop-up assembly 623 includes a sliding member 6231 and a second elastic member 6232. The second elastic member 6232 is connected to the sliding member 6231. When the bracket 61 slides into the installation cavity 621, the bracket 61 abuts against the sliding member 6231 and causes the second elastic member 6232 to store force. When the locking member 622 is disengaged from the bracket 61, the second elastic member 6232 releases the stored force to push the sliding member 6231 to move, thereby causing the bracket 61 to partially pop out of the installation cavity 621.

[0122] In this way, the second elastic member 6232 and the sliding member are connected and cooperated, so that the pop-up assembly 623 can easily pop the bracket 61 partially out of the installation cavity 621.

[0123] Specific, combined Figure 10 and Figure 12 The side of the bracket 61 is provided with a rib 616. As the bracket 61 slides into the mounting cavity 621, the rib 616 abuts the sliding member 6231 and applies pressure to the second elastic member 6232. The second elastic member 6232 can be an elastic element such as a spring. The direction of elastic deformation of the second elastic member 6232 can be the same as the sliding direction of the bracket 61. As the bracket 61 slides into the mounting cavity 621, the second elastic member 6232 is compressed and accumulates force. At the moment when the locking member 622 disengages from the bracket 61, the rib 616 stops applying pressure to the sliding member 6231. The second elastic member 6232 expands and releases its accumulated force, pushing the sliding member 6231 in the direction in which the bracket 61 slides out of the mounting cavity 621. The sliding member 6231 abuts the rib 616, thereby pushing the bracket 61 out of the mounting cavity 621. The distance the bracket 61 pops out of the mounting cavity 621 can be close to the amount of elastic deformation generated when the second elastic member 6232 releases its accumulated force.

[0124] The ejection assembly 623 further includes a receiving member 6233 having a receiving space 6234 formed therein. The first elastic member 80 can be received in the receiving space 6234. The receiving member 6233 is connected to the housing 62 and is located outside the mounting cavity 621. A sliding groove 6235 can be provided on a side of the receiving member 6233 facing the mounting cavity 621. The sliding member 6231 is located within the mounting cavity 621 and can be inserted into and slide along the sliding groove 6235.

[0125] In some embodiments, during the process of the bracket 61 sliding into the mounting cavity 621 and the sliding member 6231 pushing the bracket 61 to pop out, the sliding member 6231 may also abut against the end of the bracket 61, for example, the sliding member 6231 may abut against the end cap 618. In this embodiment, the pop-up assembly 623 may be disposed on one side of the connection between the housing 62 and the end cap 618.

[0126] See also Figure 11-13 In some embodiments, the housing 62 is formed with a first guide structure 641 , and the bracket 61 is formed with a second guide structure 642 . The first guide structure 641 and the second guide structure 642 cooperate to guide the bracket 61 to be slidably inserted into the mounting cavity 621 .

[0127] In this way, the first guide structure 641 and the second guide structure 642 cooperate to allow the shell 62 to slide easily into the installation cavity 621, while limiting the position of the bracket 61 and reducing the shaking of the cleaning assembly 60 when the cleaning robot moves.

[0128] Specifically, the mounting cavity 621 can extend along a straight path from one side of the housing 62 to the other side. The first guide structure 641 and the second guide structure 642 can be arranged along the extension path of the mounting cavity 621 to guide the bracket 61 to slide along the extension direction of the mounting cavity 621. The first guide structure 641 and the second guide structure 642 can be engaged and can slide relative to each other.

[0129] The layout direction of the first guide structure 641 and the second guide structure 642 can be roughly perpendicular to the moving direction of the cleaning robot, so that the cooperation between the first guide structure 641 and the second guide structure 642 can limit the forward and backward movement of the bracket 61 relative to the shell 62, reduce the shaking of the cleaning component 60, and help improve the cleaning effect of the cleaning part 13.

[0130] Please continue reading Figure 11-13 In some embodiments, one of the first guide structure 641 and the second guide structure 642 has a first guide rail 643 , and the other has a first guide groove 644 , and the first guide rail 643 is cooperatively connected with the first guide groove 644 .

[0131] In this way, the first guide rail 643 and the first guide groove 644 cooperate to make the first guide structure 641 and the second guide structure 642 easy to connect, and at the same time can limit the position of the bracket 61 and reduce the shaking of the cleaning assembly 60 when the cleaning robot moves.

[0132] For example, a first guide groove 644 is provided on the first guide structure 641, and a first guide rail 643 is provided on the second guide structure 642. The first guide groove 644 extends through a side wall of the mounting cavity 621. The locking member 622 can be located in the first guide groove 644, and the first guide rail 643 can have a locking groove 615 that engages with the locking member 622.

[0133] There can be two first guide slots 644 and two first guide rails 643. The two first guide slots 644 are arranged in parallel, parallel to the extension direction of the mounting cavity 621 and approximately perpendicular to the direction of travel of the cleaning robot. The sliding connection between the first guide slots 644 and the first guide rails 643 restricts the forward and backward movement of the bracket 61 relative to the housing 62 during the movement of the cleaning robot, ensuring a stable installation of the cleaning assembly 60 and improving cleaning performance.

[0134] See also Figure 12 and Figure 13 In some embodiments, the bracket 61 is formed with a first limiting portion 65 and the shell 62 is formed with a second limiting portion 66 . The first limiting portion 65 and the second limiting portion 66 cooperate to limit the movement of the bracket 61 relative to the shell 62 .

[0135] In this way, the first limiting portion 65 and the second limiting portion 66 cooperate to limit the movement of the bracket 61 relative to the shell 62, which can reduce the shaking of the bracket 61 when the cleaning robot moves.

[0136] Specifically, the bracket 61 is partially located in the mounting cavity 621, and the first limiting portion 65 and the second limiting portion 66 are formed at the connection between the bracket 61 and the inner wall surface of the mounting cavity 621. The number of the first limiting portion 65 or the second limiting portion 66 can be multiple, and the number of the first limiting portion 65 and the second limiting portion 66 is the same, and each first limiting portion 65 corresponds to a second limiting portion 66. When the bracket 61 is installed in the mounting cavity 621, the first limiting portion 65 and the second limiting portion 66 cooperate to limit the bracket 61 from translating, rotating, swinging, etc. relative to the shell 62, so that the bracket 61 is stably connected to the shell 62. In addition, when each first limiting portion 65 is aligned with the corresponding second limiting portion 66, the bracket 61 can be smoothly plugged into the mounting cavity 621, which can improve the installation and disassembly efficiency of the cleaning component 60.

[0137] See also Figure 12-15In some embodiments, one of the first limiting portion 65 and the second limiting portion 66 is provided with a limiting groove 661, and the other is provided with a limiting member 651, which is inserted into the limiting groove 661. The first limiting portion 65 is formed at the end of the bracket 61 in the sliding direction.

[0138] In this way, the stopper 651 engages with the stopper groove 661, limiting the movement of the bracket 61 relative to the housing 62 and reducing the shaking of the bracket 61 when the cleaning robot moves. The first stopper 65 is formed at the end of the bracket 61 in the sliding direction, so that the first stopper 65 is unlikely to affect the sliding of the bracket 61.

[0139] Specifically, the stopper 651 can be disposed at one end of the bracket 61 that extends into the mounting cavity 621 and fixedly connected to the main body of the bracket 61. The stopper groove 661 can be located on the wall of the housing 62 that forms the mounting cavity 621. When the bracket 61 slides into the mounting cavity 621, the stopper 651 engages with the stopper groove 661, maintaining a stable connection between the bracket 61 and the housing 62.

[0140] The limiting member 651 may include a first limiting member 6511 and a second limiting member 6512. The first limiting member 6511 cooperates with the first limiting groove 6611, and the second limiting member 6512 cooperates with the second limiting groove 6612. The first limiting member 6511 and the second limiting member 6512 may be spaced apart and arranged in a cross direction.

[0141] For example, see Figure 17 , the direction of rotation of the driving wheel 12 is the direction of travel of the cleaning robot, the direction of travel of the cleaning robot is the front, the driving wheel 12 and the cleaning assembly 60 are located at the bottom of the cleaning robot, and the direction from the top of the cleaning robot to the bottom is the direction from top to bottom. The first limiting member 6511 can be roughly perpendicular to the direction of movement of the cleaning robot, and the second limiting member 6512 is roughly perpendicular to the direction from the top of the cleaning robot to the bottom. In this way, the first limiting member 6511 cooperates with the first limiting groove 6611 to limit the movement of the bracket 61 in the front-to-back direction, and the second limiting member 6512 cooperates with the second limiting groove 6612 to limit the movement of the bracket 61 in the up-down direction. At the same time, the above two limiting cooperations jointly limit the rotation of the bracket 61 in a plane parallel to the front-to-back and up-down directions. In this embodiment, the first guide structure 641, the second guide structure 642 and the locking member 622 can be arranged along the left-right direction of the cleaning robot, and the shell 62 can cover the sides and top of the bracket 61 to further reduce the freedom of movement of the bracket 61.

[0142] The cleaning member 13 is connected to the bracket 61 and can move relative to the bracket 61 to complete cleaning tasks such as wiping and scrubbing. The first limiter 65 and the second limiter 66 cooperate to reduce the shaking of the bracket 61 caused by the movement of the cleaning member 13 during the cleaning process, which is conducive to improving the cleaning effect.

[0143] See also Figure 12 and Figure 15 In some embodiments, the bracket 61 may include a support shaft 611, a side plate 612, and an end cover 618. The support shaft 611 may be in the shape of a rectangular strip, the side plate 612 may be in the shape of a curved sheet, the side plate 612 may be connected to the body 10 and form a partial circumferential contour of the cleaning robot, and the support shaft 611 is arranged along the normal direction of the side plate 612 and on the concave side. The end cover 618 may be in the shape of a sheet, opposite to the side plate 612 along the sliding direction of the bracket 61. In the process of the bracket 61 sliding into the installation cavity 621, the end cover 618 is the end of the bracket 61 that first enters the installation cavity 621. The first limiting portion 65 is formed on the end cover 618. In the process of the bracket 61 sliding, the direction in which the first limiting portion 65 protrudes or recesses is the same as the sliding direction of the bracket 61, so the first limiting portion 65 is not easy to interfere with the sliding of the bracket 61.

[0144] Please refer again Figure 9 In some embodiments, the cleaning member 13 includes a roller brush 131 , and the bracket 61 is slidably disposed in the mounting cavity 621 along the axial direction of the roller brush 131 .

[0145] In this way, the roller brush 131 can be slidably installed on the main body or slidably removed from the main body along the axial direction of the roller brush 131 along with the bracket 61.

[0146] Specifically, the roller brush 131 may be cylindrical, the axial direction of the support shaft 611 of the bracket 61 may be consistent with the axial direction of the roller brush 131, and the first guide structure 641 and the second guide structure 642 may be arranged to be parallel to the axial direction of the roller brush 131. Figure 10 and Figure 9 The bracket 61 slides along the axial direction of the roller brush 131 into the mounting cavity 621, and the cleaning assembly 60 is completely installed in the housing 62. The bracket 61 slides out of the mounting cavity 621 along the axial direction of the roller brush 131, and the cleaning assembly 60 is removed from the housing 62. Removing the cleaning assembly 60 from the housing 62 facilitates cleaning or replacement of the roller brush 131.

[0147] Combine Figure 11 A drive shaft 132 may be provided in the mounting cavity 621 , and the drive shaft 132 may drive the roller brush 131 to rotate. The rotation direction of the roller brush 131 may be consistent with the driving wheel 12 , so that the roller brush 131 may clean the floor by rolling while the cleaning robot is moving.

[0148] See also Figure 2and Figure 10 When the cleaning assembly 60 is inserted into the mounting cavity 621, the direction in which the bracket 61 slides is consistent with the second movement direction b. In the event that the drive shaft 132 and the connector 22 are misaligned, the drive shaft 132 abuts against the connector 22, causing the connector 22 to move relative to the roller 21 in the first movement direction, i.e., the direction opposite to the sliding direction of the bracket 61. This allows the bracket 61 to be inserted into the mounting cavity, while the roller 21 and the housing 62 remain relatively fixed. Furthermore, as the drive shaft 132 rotates, the connector 22 aligns with the drive shaft 132, and the elastic mechanism 23 releases its stored force, pushing the connector 22 in the second movement direction and completing its insertion into the drive shaft 132.

[0149] In this way, the cleaning assembly 60 can be inserted into the installation cavity when the driving shaft 132 and the connecting member 22 are misaligned, thereby improving the replacement efficiency of the cleaning assembly 60.
