[0002] Some floor scrubbers now come with a front squeegee assembly to remove residual water from the floor and enable quick drying. This assembly includes a robotic arm, and the scrubber has an internal servo motor. One end of the robotic arm is mounted on the servo motor, which moves the squeegee up and down. However, incorrect installation of the robotic arm onto the servo motor can easily lead to jamming, preventing the squeegee from functioning properly and impacting the customer experience. Summary of the Invention

[0003] The purpose of this application is to provide a cleaning base, cleaning equipment, and cleaning system to solve the technical problem in the prior art where installation errors can easily occur when installing a robotic arm on a servo motor assembly, leading to jamming.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: This application provides a cleaning seat, comprising: The shell has a receiving cavity inside, and the shell is provided with a clearance hole that communicates with the receiving cavity; A drive assembly is disposed in the receiving cavity. The drive assembly includes a drive body and a swing arm connected to the drive body. The drive body can drive the swing arm to swing around the rotation axis of the drive body. The swing arm is provided with a mating groove. The connecting arm is located on the outside of the housing. The connecting arm has a mating protrusion and a clearance hole to prevent the mating protrusion from inserting into the mating groove. The swing arm can prevent the mating protrusion from passing through the mating groove and inserting into the housing.

[0005] In some implementations, a mating surface is formed on the swing arm, and a mating groove is set on the mating surface. When the swing arm drives the connecting arm to move, the projection of the clearance hole onto the mating surface always falls completely on the mating surface.

[0006] In some implementations, the swing arm includes a first arm segment and a second arm segment. The first arm segment is connected to the drive body, and the second arm segment is connected to the second arm segment. The second arm segment is located directly below the clearance hole and is used to prevent the mating protrusion from passing through the mating groove and inserting into the housing.

[0007] In some implementations, the second arm segment is positioned to fit against the inner surface of the housing.

[0008] In some implementations, the swing arm includes a first arm, a connecting arm, and a second arm. The first arm is disposed within the receiving cavity and connected to the drive body, while the second arm is disposed outside the receiving cavity. The connecting arm passes through a clearance hole and connects the first arm and the second arm. A mating groove is disposed on the second arm and the connecting arm, and the second arm is used to prevent the mating protrusion from passing through the mating groove and inserting into the housing.

[0009] In some implementations, the second arm is fitted to the outer surface of the housing.

[0010] In some implementations, the housing includes an upper shell portion disposed above the drive body, the upper shell portion having a clearance hole, and a water-blocking protrusion disposed on the outer side of the upper shell portion, the water-blocking protrusion being arranged around the clearance hole.

[0011] In some implementations, the drive body includes a top cover, and the top cover and the inner side of the housing form a mounting cavity, with the swing arm disposed in the mounting cavity.

[0012] In some implementations, a first seal is provided between the inner surface of the top cover and the housing to seal both, and the first seal is disposed around the mounting cavity.

[0013] In some implementations, the housing also includes a lower housing portion located below the drive body, with the upper cover having a drain hole communicating with the mounting cavity, and the lower housing portion forming a flow channel, one end of which is connected to the drain hole and the other end of which is connected to the bottom surface of the lower housing portion.

[0014] In some implementations, an inlet hole connected to the mounting cavity is provided within the groove.

[0015] This application provides a cleaning seat, comprising: The shell has a receiving cavity inside, and the shell is provided with a clearance hole that communicates with the receiving cavity; A drive assembly is disposed in the receiving cavity. The drive assembly includes a drive body and a swing arm connected to the drive body. The drive body can drive the swing arm to swing around the rotation axis of the drive body. The swing arm is provided with a mating protrusion. The connecting arm is located on the outside of the housing. The connecting arm has a mating groove, and the clearance hole avoids the mating protrusion from inserting into the mating groove.

[0016] This application provides a cleaning device, including a main unit and a cleaning seat as described in any of the above technical solutions, wherein the main unit is connected to the cleaning seat.

[0017] This application provides a cleaning system, including a pile and the cleaning equipment described in the above technical solution, wherein the pile is adapted to the cleaning equipment.

[0018] The beneficial effects of this application are as follows: The cleaning base provided by this application can prevent the mating protrusion from passing through the mating groove and inserting into the housing by setting the swing arm. This ensures that when the connecting arm is installed on the swing arm, only the mating protrusion can be inserted into the mating groove on the swing arm. This avoids the situation in related technologies where the mechanical arm is easily jammed due to installation errors when installed on the servo assembly. This application achieves the effect of foolproof design by limiting the structure of the swing arm, thereby improving the user experience.

[0019] The cleaning base provided in this application has a mating protrusion on the limiting swing arm and a mating groove on the connecting arm. Since the mating protrusion has passed through the clearance hole on the housing, when installing the connecting arm on the swing arm, it is only necessary to insert the mating protrusion into the mating groove on the connecting arm. This avoids the situation in related technologies where the mechanical arm is easily jammed due to installation errors when installed on the servo assembly, thereby improving the user experience.

[0030] It should be noted that, before describing the embodiments of this application, the relevant technologies will be described first.

[0031] Please see Figures 1-2 , Figure 1 This is a partial structural diagram of a cleaning seat in related technologies. Figure 2 for Figure 1 A magnified view of a portion of point A in the middle.

[0032] A floor scrubber is a floor cleaning device. It includes a cleaning base; please refer to [link / reference]. Figure 1 Some existing floor scrubbers include a front squeegee assembly 10a in their cleaning body. The front squeegee assembly 10a is used to scrape off residual water stains on the floor in order to achieve the requirement of quick floor drying.

[0033] The cleaning unit houses the servo motor assembly. Please also refer to [link / reference needed]. Figure 1 and Figure 2The front scraper assembly 10a includes a robotic arm 11a, one end of which is mounted on a servo motor assembly. When the servo motor assembly moves, it can drive the scraper 12a of the front scraper assembly 10a to move up and down. That is, when the scraper 12a of the front scraper assembly 10a needs to scrape away residual water stains on the ground, the servo motor assembly can be controlled to lower the height of the scraper 12a so that the scraper 12a contacts the ground; when the scraper 12a of the front scraper assembly 10a does not need to scrape away residual water stains on the ground, the servo motor assembly can be controlled to raise the height of the scraper 12a so that there is a distance between the scraper 12a and the ground.

[0034] For information on the connection between the servo motor assembly and the robotic arm 11a, please refer to [link / reference]. Figure 2 The servo assembly includes a servo arm 20a and a mechanical arm 11a with a mounting protrusion 13a. The mounting protrusion 13a is inserted into the connecting groove 21a on the servo arm 20a so that when the servo arm 20a swings, it can drive the mechanical arm 11a to move, thereby realizing the lifting and lowering function of the scraper 12a.

[0035] Please see Figure 2 The housing of the cleaning unit has a clearance groove 30a. The mounting protrusion 13a on the robotic arm 11a needs to pass through the clearance groove 30a to insert into the servo arm 20a. However, when installing the robotic arm 11a onto the servo arm 20a, users may mistakenly consider the clearance groove 30a as the installation position and insert the mounting protrusion 13a into the clearance groove 30a, believing that the robotic arm 11a is assembled in place. This can lead to a situation where the mounting protrusion 13a is inserted into the clearance groove 30a but not into the connecting groove 21a of the servo arm 20a, i.e., the mounting protrusion 13a is installed as if... Figure 2 The insertion clearance slot 30a is shown and is located on one side of the servo arm 20a. When the servo assembly moves, the servo arm 20a will swing and abut against the mounting protrusion 13a, causing the servo arm 20a to swing and get stuck, preventing the scraper 12a from functioning normally. At this time, the user will think that the floor scrubber is malfunctioning, which will affect the customer experience.

[0036] Additionally, when the user installs the mounting protrusion 13a to such a position... Figure 2 When the insertion clearance slot 30a is shown and located on one side of the servo arm 20a, it is easy to get your fingers caught between the servo arm 20a and the robotic arm 11a, which poses a certain safety hazard.

[0037] In view of the above problems, this application provides a cleaning base, cleaning equipment and cleaning system to solve the problem that the robot arm is prone to jamming due to installation errors when it is installed on the servo motor assembly. The embodiments of this application are described below with reference to the accompanying drawings.

[0038] Please see Figures 3-5 , Figure 3This is a partial structural diagram of a cleaning seat provided in some embodiments of this application. Figure 4 for Figure 3 A magnified view of a portion of point B in the diagram. Figure 5 This is a schematic diagram of the structure of the driving component 20 provided in some embodiments of this application.

[0039] For ease of description, please refer to Figure 3 In this embodiment, the length direction of the cleaning seat is defined as the X-axis direction, the width direction as the Y-axis direction, and the height direction as the Z-axis direction, wherein the X-axis, Y-axis, and Z-axis directions are mutually perpendicular. It should be noted that the dimension in the length direction is not necessarily larger than the dimension in the depth direction.

[0040] In addition, this embodiment uses directional terms such as "up," "down," "front," "back," "left," and "right" when describing the cleaning seat. The orientation is mainly based on the location of the cleaning seat on the attached... Figure 3 The directions shown are described as follows: "up" is the positive direction of the Z-axis, "down" is the negative direction of the Z-axis, "front" is the positive direction of the Y-axis, "back" is the negative direction of the Z-axis, "right" is the positive direction of the X-axis, and "left" is the negative direction of the X-axis.

[0041] Please see Figure 3 and Figure 4 The cleaning seat provided in this application embodiment includes a housing 10, a drive assembly 20, and a connecting arm 31.

[0042] Regarding the housing 10, the housing 10 mainly serves to support other components of the cleaning seat. It can be understood that a receiving cavity is formed inside the housing 10, and some components of the cleaning seat are located in the receiving cavity.

[0043] The drive assembly 20 is disposed in the receiving cavity, which can be understood as the drive assembly 20 being completely located inside the receiving cavity; in addition, if most of the drive assembly 20 is located inside the receiving cavity and part of the drive assembly 20 extends out of the housing 10, it can also be understood as the drive assembly 20 being disposed in the receiving cavity.

[0044] Please see Figure 4 The drive assembly 20 includes a drive body 21 and a swing arm 22 connected to the drive body 21. The drive body 21 can drive the swing arm 22 to swing around the rotation axis L of the drive body 21.

[0045] In some examples, the drive unit 21 can be set as a servo structure. The servo structure usually integrates a drive motor, a reduction gear mechanism, a position feedback element and a control circuit board. The servo structure can receive external control commands to form a closed-loop adjustment, drive the shaft to rotate to the target angle and maintain the position, and achieve precise angular displacement output.

[0046] Please see Figure 3 The cleaning seat includes a scraper assembly 30, which is used to scrape away residual water stains on the floor, achieving the requirement of quick floor drying. The connecting arm 31 is part of the scraper assembly 30, and the scraper assembly 30 is connected to the swing arm 22 via the connecting arm 31; additionally, please refer to... Figure 3 The squeegee assembly 30 also includes a cleaning squeegee 32 for scraping away residual water stains on the ground, which can be raised and lowered when the drive assembly 20 is activated.

[0047] In some examples, the connecting arm 31 can be configured to move along the drive component 20 when the drive component 20 is activated. Figure 3 The connecting arm 31 reciprocates along the X-axis. Figure 3 When the cleaning blade 32 reciprocates in the X-axis direction, it can be used in conjunction with other transmission structures of the scraper assembly 30 to achieve reciprocating motion of the cleaning blade 32 along the height direction. It should be noted that the specific structure of the other transmission structures described herein is not specifically limited in this embodiment, and existing related technologies can be used.

[0048] Please also see Figure 3 The cleaning unit also includes a cleaning component 40, and a cleaning scraper 32 is located in front of the cleaning component 40. The cleaning component 40 can be a roller brush or a brush plate, etc. The cleaning component 40 is rotatably connected to the housing 10.

[0049] Please see Figure 4 The housing 10 is provided with a clearance hole 11, which is connected to the interior of the housing 10, that is, the clearance hole 11 is connected to the receiving cavity. The swing arm 22 is provided with a mating groove 221, and the connecting arm 31 is provided with a mating protrusion 33. The clearance hole 11 is used to allow the mating protrusion 33 to be inserted into the mating groove 221.

[0050] Regarding the clearance hole 11 used to avoid the insertion of the mating protrusion 33 into the mating groove 221, that is, the clearance hole 11 is used to avoid the connection between the mating protrusion 33 and the mating groove 221. It can be understood that by inserting the mating protrusion 33 into the mating groove 221, the connecting arm 31 is connected to the swing arm 22, so that when the swing arm 22 moves, it can drive the connecting arm 31 to move.

[0051] Please see Figure 6 , Figure 6 This is a partial schematic diagram of the structure of the cleaning seat provided in some embodiments of this application.

[0052] Please see Figure 6 When the mating protrusion 33 is misaligned with the mating groove 221 and along Figure 6When the Z-axis moves downward, the blocking effect of the swing arm 22 prevents the mating protrusion 33 from passing through the mating groove 221 and inserting into the housing 10. In other words, in this embodiment, by limiting the structure of the swing arm 22, the swing arm 22 can prevent the mating protrusion 33 from passing through the mating groove 221 and inserting into the housing 10.

[0053] As described in the above-mentioned related technologies, when a robotic arm is installed on a servo motor assembly, installation errors can easily occur, leading to jamming. However, in this embodiment, by setting the swing arm 22 to prevent the mating protrusion 33 from passing through the mating groove 221 and inserting into the housing 10, when the connecting arm 31 is installed on the swing arm 22, only the mating protrusion 33 can be inserted into the mating groove 221 on the swing arm 22. This avoids the situation in the related technologies where the robotic arm is easily installed on a servo motor assembly and jamming due to installation errors. This embodiment achieves the effect of foolproof design by limiting the structure of the swing arm 22, thereby improving the user experience.

[0054] It should be noted that, since the limiting connecting arm 31 can move along... Figure 3 The connecting arm 31 moves back and forth along the X-axis. Figure 3 When the movement occurs in the X-axis direction, the distance between the center of the protrusion 33 and the rotation axis L of the drive assembly 20 changes. This is to achieve the effect that when the swing arm 22 swings around the rotation axis L, it drives the connecting arm 31 along... Figure 3 For movement along the X-axis, the shape of the mating groove 221 needs to be set so that when the swing arm 22 swings around the rotation axis L, the mating protrusion 33 can slide relative to the swing arm 22 within the mating groove 221, so that the distance between the center of the mating protrusion 33 and the rotation axis L of the drive assembly 20 changes. For example, in some examples, the length direction of the mating groove 221 is set to extend along the direction close to the rotation axis L.

[0055] Please see Figures 7-9 , Figures 7-9 This is a partial schematic diagram of the cleaning seat structure when the swing arm 22 is in the first position, the second position and the third position, respectively, according to some embodiments of this application.

[0056] In some embodiments, see Figure 5 and Figure 7 The swing arm 22 has a mating surface 222, wherein a mating groove 221 is provided on the mating surface 222. When the swing arm 22 drives the connecting arm 31 to move, the projection of the clearance hole 11 onto the mating surface 222 always falls completely on the mating surface 222.

[0057] Please see Figure 7 This indicates that the swing arm 22 is in the first position, at which point the projection of the clearance hole 11 onto the mating surface 222 falls completely on the mating surface 222; please refer to... Figure 8This illustrates that the swing arm 22 is in the second position, at which point the projection of the clearance hole 11 onto the mating surface 222 falls completely on the mating surface 222; please refer to... Figure 9 This illustrates that the swing arm 22 is in the third position, at which point the projection of the clearance hole 11 onto the mating surface 222 falls completely on the mating surface 222. The first and third positions can be understood as the two extreme positions of the swing arm 22 when it rotates around the rotation axis L of the driving body 21 under the drive of the driving body 21. The second position is the position of the swing arm 22 in an intermediate state between the first and third positions.

[0058] In this embodiment, by setting the projection of the avoidance hole 11 onto the mating surface 222 when the swing arm 22 drives the connecting arm 31 to move, the swing arm 22 can prevent the mating protrusion 33 from passing through the mating groove 221 and inserting into the housing 10.

[0059] Please see Figure 10 , Figure 10 This is a partial schematic diagram of the structure of the cleaning seat portion when the swing arm 22 is in the first position according to some embodiments of this application.

[0060] In some embodiments, see Figure 10 When the swing arm 22 is in the first position, the projection of the clearance hole 11 onto the mating surface 222 does not fall completely on the mating surface 222. Please refer to [link / reference]. Figure 10 , Figure 10 The dashed box roughly outlines the area where the clearance hole 11 does not fall onto the mating surface 222 of the swing arm 22 when projected onto the swing arm 22 in its first position. For ease of description, [the area is...]. Figure 10 The area enclosed by the dashed box in the middle is called the first region 111. The size of the first region 111 is smaller than the size of the mating protrusion 33, so as to prevent the mating protrusion 33 from passing through the first region 111, passing through the clearance hole 11, and inserting into the housing 10.

[0061] In other words, when the swing arm 22 is in the first position, it is not necessary to ensure that the projection of the clearance hole 11 onto the mating surface 222 is completely on the mating surface 222, as long as the swing arm 22 can still prevent the mating protrusion 33 from passing through the mating groove 221 and inserting into the housing 10.

[0062] Please see Figure 11 , Figure 11 This is a partial schematic diagram of the structure of the cleaning seat portion when the swing arm 22 is in the third position according to some embodiments of this application.

[0063] In some embodiments, see Figure 11 When the swing arm 22 is in the third position, the projection of the clearance hole 11 onto the mating surface 222 does not fall completely on the mating surface 222. Please refer to [link / reference]. Figure 11, Figure 11 The dashed box roughly outlines the area where the clearance hole 11 does not fall onto the mating surface 222 of the swing arm 22 when projected onto the swing arm 22 in the third position. For ease of description, [the area is...]. Figure 11 The area enclosed by the dashed box in the middle is called the second region 112. The size of the second region 112 is smaller than the size of the mating protrusion 33, so as to prevent the mating protrusion 33 from passing through the second region 112, passing through the clearance hole 11, and inserting into the housing 10.

[0064] In other words, when the swing arm 22 is in the third position, it is not necessary to ensure that the projection of the clearance hole 11 onto the mating surface 222 is completely on the mating surface 222, as long as the swing arm 22 can still prevent the mating protrusion 33 from passing through the mating groove 221 and inserting into the housing 10.

[0065] Please see Figures 12-13 , Figure 12 This is a schematic diagram of the structure of the driving component 20 provided in some embodiments of this application. Figure 13 This is a partial cross-sectional schematic diagram of a cleaning seat provided in some embodiments of this application.

[0066] In some embodiments, see Figure 12 The swing arm 22 includes a first arm segment 223 and a second arm segment 224. The first arm segment 223 is located inside the housing 10 and connected to the drive body 21. The second arm segment 224 is connected to the first arm segment 223. Please refer to [link to relevant documentation]. Figure 13 The second arm segment 224 is disposed inside the housing 10 and located directly below the clearance hole 11. The second arm segment 224 can prevent the mating protrusion 33 from passing through the mating groove 221 and inserting into the housing 10.

[0067] Please see Figure 12 The drive assembly 20 includes an output shaft 211, which is connected to the first arm segment 223. The axis of the output shaft 211 is the rotation axis L of the drive assembly 20. When the output shaft 211 rotates, it can drive the first arm segment 223 and the second arm segment 224 to swing. The side of the second arm segment 224 facing the clearance hole 11 forms a mating surface 222.

[0068] In this embodiment of the application, by setting the swing arm 22 to include a first arm segment 223 and a second arm segment 224, the structure of the swing arm 22 can be simplified as much as possible while ensuring that the second arm segment 224 can block the mating protrusion 33 from passing through the mating groove 221 and inserting into the housing 10.

[0069] When the swing arm 22 includes a first arm segment 223 and a second arm segment 224, see some examples. Figure 12The second arm segment 224 can be set to be arc-shaped, and the first arm segment 223 and the second arm segment 224 are connected at the middle position along the bending direction. The mating groove 221 is set at the middle position along the bending direction of the second arm segment 224. In this way, the second arm segment 224 can prevent the mating protrusion 33 from passing through the mating groove 221 and inserting into the housing 10, while minimizing the length of the second arm segment 224.

[0070] When the swing arm 22 includes a first arm segment 223 and a second arm segment 224, in some examples, the swing arm 22 can be configured as a one-piece molded structure, such as the swing arm 22 being integrally injection molded or 3D printed; or, in other examples, the second arm segment 224 can be assembled on the first arm segment 223, such as the second arm segment 224 being tightly fitted or glued to the first arm segment 223.

[0071] When the swing arm 22 includes a first arm segment 223 and a second arm segment 224, see some examples. Figure 13 The second arm segment 224 is fitted to the inner side of the housing 10.

[0072] In this embodiment, by limiting the second arm segment 224 to fit the inner side of the housing 10, it is possible not only to prevent water on the top surface of the housing 10 from entering the housing 10 through the space between the second arm segment 224 and the inner side of the housing 10, but also to improve the aesthetics of the cleaning seat.

[0073] It should be noted that some embodiments described above show the second arm segment 224 fitting against the inner side of the housing 10. In other embodiments, the second arm segment 224 may be fitted with a clearance fit against the inner side of the housing 10.

[0074] When the swing arm 22 includes a first arm segment 223 and a second arm segment 224, in some examples, the clearance hole 11 can be provided as follows: Figure 11 The diagram shows a straight line.

[0075] Please see Figure 14 , Figure 14 This is a schematic diagram of the structure of a cleaning seat portion provided in some embodiments of this application.

[0076] When the swing arm 22 includes a first arm segment 223 and a second arm segment 224, in some examples, the clearance hole 11 can be provided as follows: Figure 14 The shape shown is an arc.

[0077] It should be noted that when the clearance hole 11 is arc-shaped, the width of the clearance hole 11 in the radial direction needs to be set appropriately so that the mating protrusion 33 can move along the arc. Figure 14 It moves back and forth along the X-axis.

[0078] Please see Figures 15-16 , Figure 15 This is a schematic diagram of the structure of the driving component 20 provided in some embodiments of this application. Figure 16 This is a partial cross-sectional schematic diagram of a cleaning seat provided in some embodiments of this application.

[0079] It should be noted that some embodiments described above depict the swing arm 22 including a first arm segment 223 and a second arm segment 224. For other embodiments, please refer to [link to relevant documentation]. Figure 15 The swing arm 22 includes a first arm 225, a connecting arm 226, and a second arm 227. The first arm 225 is disposed inside the housing 10 and connected to the drive body 21. The second arm 227 is disposed outside the housing 10. The connecting arm 31 passes through the clearance hole 11 and connects the first arm 225 and the second arm 227. The mating groove 221 is disposed on the second arm 227 and the connecting arm 226. The second arm 227 covers the second arm 227, that is, the second arm 227 can prevent the mating protrusion 33 from passing through the mating groove 221 and inserting into the housing 10.

[0080] Please see Figure 15 The drive assembly 20 includes an output shaft 211, which is connected to the first arm 225. The axis of the output shaft 211 is the rotation axis L of the drive assembly 20. When the output shaft 211 rotates, it can drive the first arm 225, the connecting arm 226 and the second arm 227 to swing. The mating surface 222 is formed on the second arm 227.

[0081] In this embodiment of the application, by defining the swing arm 22 as including a first arm portion 225, a connecting arm portion 226 and a second arm portion 227, the second arm portion 227 can be positioned on the outside of the housing 10 to block the clearance hole 11.

[0082] When the swing arm 22 includes a first arm portion 225, a connecting arm portion 226, and a second arm portion 227, since the connecting arm portion 226 passes through the clearance hole 11 and the movement trajectory of the connecting arm portion 226 is arc-shaped, in some examples, the shape of the clearance hole 11 can be set to be arc-shaped to minimize the area of ​​the clearance hole 11.

[0083] When the swing arm 22 includes a first arm portion 225, a connecting arm portion 226, and a second arm portion 227, see some examples. Figure 15 The second arm 227 can be set to be arc-shaped, and the connecting arm 226 is connected to the middle position of the second arm 227 along the bending direction. The mating groove 221 is set at the middle position of the second arm 227 along the bending direction. In this way, while the second arm 227 can prevent the mating protrusion 33 from passing through the mating groove 221 and inserting into the housing 10, the length and size of the second arm 227 can be reduced as much as possible.

[0084] When the swing arm 22 includes a first arm portion 225, a connecting arm portion 226, and a second arm portion 227, in some examples, the second arm portion 227 may be assembled on the connecting arm portion 226, or the connecting arm portion 226 and the second arm portion 227 may be an integral structure with the connecting arm portion 226 assembled on the first arm portion 225, so as to facilitate the assembly of the swing arm 22.

[0085] When the swing arm 22 includes a first arm portion 225, a connecting arm portion 226, and a second arm portion 227, see some examples. Figure 15 The groove 221 is connected to the connecting arm 226 and the second arm 227 on the side opposite to the first arm 225, so as to facilitate the machining of the groove 221.

[0086] In some embodiments, see Figure 16 The second arm 227 is fitted to the outer side of the housing 10.

[0087] In this embodiment, by limiting the second arm portion 227 to fit against the outer side of the housing 10, water on the top surface of the housing 10 can be prevented from entering the housing 10 through the space between the second arm portion 227 and the outer side of the housing 10. At the same time, the height of the second arm portion 227 protruding from the housing 10 can be minimized, thus improving the aesthetics of the cleaning seat.

[0088] It should be noted that some embodiments described above show the second arm segment 224 fitting against the inner side of the housing 10. In other embodiments, the second arm portion 227 may also be provided with a clearance fit against the outer side of the housing 10.

[0089] Please see Figure 17 , Figure 17 This is a partial structural schematic diagram of a cleaning seat provided in some embodiments of this application.

[0090] In some embodiments, see Figure 17 The housing 10 includes an upper housing portion 12 disposed above the drive body 21. The upper housing portion 12 is provided with a clearance hole 11. A water-blocking protrusion 13 is provided on the outer side of the upper housing portion 12, and the water-blocking protrusion 13 is disposed around the clearance hole 11.

[0091] In this embodiment of the application, by limiting the water-blocking protrusion 13 to be arranged around the avoidance hole 11, the water flow on the top surface of the upper shell 12 can be blocked from flowing to the avoidance hole 11.

[0092] It should be noted that when the swing arm 22 includes a first arm portion 225, a connecting arm portion 226, and a second arm portion 227, it is not necessary to provide a water-blocking protrusion 13 on the outer side of the upper shell portion 12 so that the second arm portion 227 can be fitted to the outer side of the shell 10.

[0093] When a water-blocking protrusion 13 is provided on the outer side of the upper shell 12, in some examples, the water-blocking protrusion 13 can be integrally formed on the upper shell 12 to facilitate the processing and forming of the water-blocking protrusion 13.

[0094] Please see Figure 18 , Figure 18 This is a partial cross-sectional schematic diagram of a cleaning seat provided in some embodiments of this application.

[0095] In some embodiments, see Figure 15 and Figure 18 The drive body 21 includes an upper cover 212, please refer to [link / reference]. Figure 18 The upper cover 212 and the inner side of the housing 10 form a mounting cavity 50, and the swing arm 22 is disposed in the mounting cavity 50.

[0096] Please see Figure 15 The drive body 21 also includes a housing body 213, with a top cover 212 positioned above and connected to the housing body 213. Other components of the drive body 21 are housed within the housing body 213 and the top cover 212. (See [link to relevant documentation]). Figure 15 The output shaft 211 of the drive body 21 passes through the upper cover 212 and is connected to the swing arm 22.

[0097] See some examples. Figure 15 The upper cover 212 has a receiving groove 2121, and the swing arm 22 is disposed in the receiving groove 2121. The receiving groove 2121 and the inner side of the upper shell 12 cooperate to form an installation cavity 50.

[0098] In some embodiments, see Figure 18 A first seal 60 for sealing the upper cover 212 and the inner side of the housing 10 is provided, and the first seal 60 is provided around the mounting cavity 50.

[0099] In this embodiment, by limiting the inner side of the upper cover 212 and the housing 10 to be sealed together by the first sealing member 60, water entering the upper cover 212 through the clearance hole 11 is prevented from overflowing into the interior of the cleaning seat through the gap between the upper cover 212 and the housing 10, thereby preventing water from entering some components inside the cleaning seat.

[0100] See some examples. Figure 18 An annular groove 121 is provided on the inner side of the upper shell 12, and the first seal 60 is disposed in the annular groove 121. Please refer to [link / reference]. Figure 15 The upper cover 212 includes an annular plate portion 2122 for forming a receiving groove 2121, see [link to relevant documentation]. Figure 18 The annular plate portion 2122 is inserted into the annular groove 121 and squeezes the first seal 60 so that the first seal 60 seals the upper cover 212 and the upper shell portion 12.

[0101] In some embodiments, see Figure 17 The housing 10 also includes a lower housing portion 14 disposed below the drive body 21. The lower housing portion 14 is connected to the upper housing portion 12, and the upper housing portion 12 and the lower housing portion 14 together form a receiving cavity for the housing 10; see also Figure 18 The upper cover 212 is provided with a drain hole 2123 that communicates with the mounting cavity 50, and the lower shell 14 is provided with a guide channel 141. One end of the guide channel 141 is connected to the drain hole 2123 and the other end is connected to the bottom surface of the lower shell 14.

[0102] When water enters the mounting cavity 50 formed by the upper cover 212 and the upper shell 12, the water can flow to the surface to be cleaned through the drain hole 2123 on the upper cover 212 and the guide channel 141 on the lower shell 14. The water flowing to the surface to be cleaned through the guide channel 141 can be cleaned by the cleaning component 40 on the cleaning seat.

[0103] In this embodiment, drainage holes 2123 and flow channels 141 are provided on the upper cover 212 and the lower shell 14 respectively, so as to drain the water in the mounting cavity 50 in a timely manner and prevent the long-term presence of water in the mounting cavity 50 from causing odors and other problems.

[0104] In some examples, to facilitate the drainage of water in the mounting cavity 50 through the drain hole 2123, the drain hole 2123 may be located at the lowest point of the upper cover 212, so that the water in the mounting cavity 50 can flow to the drain hole 2123 under the action of gravity.

[0105] See some examples. Figure 18 An insertion portion 2124 is formed on the upper cover 212 for inserting into the road channel. The insertion portion 2124 is connected to the drain hole 2123 and inserted into the guide channel 141. The insertion portion 2124 not only facilitates the positioning and installation of the upper cover 212 on the lower shell 14, but also facilitates the connection between the drain hole 2123 and the guide channel 141. In other examples, the upper cover 212 may not have an insertion portion 2124.

[0106] When the upper cover 212 and the lower shell 14 are respectively provided with drainage holes 2123 and flow guiding channels 141, in some embodiments, please refer to Figure 12 The swing arm 22 has a liquid inlet hole 228 on its mating groove 221. Water on the top surface of the upper shell 12 can enter the mounting cavity 50 through the liquid inlet hole 228 and then be discharged through the drain hole 2123 and the guide channel 141.

[0107] In this embodiment, by providing a liquid inlet hole 228 on the mating groove 221 of the limiting swing arm 22, when there is a relatively large amount of water on the top surface of the upper shell 12, it can enter the mounting cavity 50 in time through the liquid inlet hole 228 and be discharged through the drain hole 2123 and the guide channel 141.

[0108] See some examples. Figure 12 A liquid inlet hole 228 is provided on the bottom surface of the groove 221 to allow water in the groove 221 to enter the mounting cavity 50 in a timely manner through the liquid inlet hole 228, thus preventing water from remaining in the groove 221.

[0109] In some embodiments, see Figure 18 The insertion part 2124 is provided with a second sealing element 70, and the insertion part 2124 is pressed against the bottom surface of the upper cover 212 by the lower shell part 14.

[0110] Please see Figures 19-20 , Figure 19 This is an exploded view of the cleaning seat portion structure provided in some embodiments of this application. Figure 20 A partial cross-sectional view of a cleaning seat provided for some embodiments of this application.

[0111] It should be noted that in the cleaning seat described in some of the embodiments above, a mating groove 221 is provided on the swing arm 22 and a mating protrusion 33 is provided on the connecting arm 31. In other embodiments, a mating protrusion 33 can be provided on the swing arm 22 and a mating groove 221 can be provided on the connecting arm 31, as will be described in detail below.

[0112] Please see Figure 19 and Figure 20 The cleaning seat provided in this application embodiment includes a housing 10, a drive assembly 20, and a connecting arm 31.

[0113] Regarding the housing 10, the housing 10 mainly serves to support other components of the cleaning seat. It can be understood that a receiving cavity is formed inside the housing 10, and some components of the cleaning seat are located in the receiving cavity.

[0114] The drive assembly 20 is disposed in the receiving cavity, which can be understood as the drive assembly 20 being completely located inside the receiving cavity; in addition, if most of the drive assembly 20 is located inside the receiving cavity and part of the drive assembly 20 extends out of the housing 10, it can also be understood as the drive assembly 20 being disposed in the receiving cavity.

[0115] Please see Figure 20 The drive assembly 20 includes a drive body 21 and a swing arm 22 connected to the drive body 21. The drive body 21 can drive the swing arm 22 to swing around the rotation axis of the drive body 21.

[0116] The connecting arm 31 is part of the structure of the scraper assembly 30, and the scraper assembly 30 is connected to the swing arm 22 through the connecting arm 31.

[0117] Please see Figure 19 The housing 10 is provided with a clearance hole 11, which is connected to the interior of the housing 10, i.e., the clearance hole 11 is connected to the receiving cavity. The swing arm 22 is provided with a mating protrusion 33, and the connecting arm 31 is provided with a mating groove 221. The clearance hole 11 is used to allow the mating protrusion 33 to be inserted into the mating groove 221, i.e., the mating protrusion 33 passes through the clearance hole 11 and is inserted into the mating groove 221 on the connecting arm 31. It can be understood that by inserting the mating protrusion 33 into the mating groove 221, the connecting arm 31 is connected to the swing arm 22, so that when the swing arm 22 moves, it drives the connecting arm 31 to move.

[0118] As described in the above-mentioned related technologies, when a robotic arm is installed on a servo motor assembly, installation errors can easily occur, leading to jamming. However, in this embodiment, by providing a mating protrusion 33 on the swing arm 22 and a mating groove 221 on the connecting arm 31, since the mating protrusion 33 has already passed through the clearance hole 11 on the housing 10, when installing the connecting arm 31 on the swing arm 22, it is only necessary to insert the mating protrusion 33 into the mating groove 221 on the connecting arm 31. This avoids the situation in the related technologies where the robotic arm is easily installed on a servo motor assembly and jams due to installation errors, thereby improving the user experience.

[0119] It should be noted that, since the limiting connecting arm 31 can move along... Figure 19 Reciprocating movement along the X-axis, i.e., connecting arm 31 along... Figure 19 When the movement occurs along the X-axis, the distance between the center of the protrusion 33 and the axis of rotation of the main body 21 changes. This is to achieve the effect that when the swing arm 22 swings around the axis of rotation, it drives the connecting arm 31 along... Figure 19 For movement along the X-axis, the shape of the mating groove 221 needs to be set so that when the swing arm 22 swings around the rotation axis, the mating protrusion 33 can slide relative to the swing arm 22 within the mating groove 221, thereby changing the distance between the center of the mating protrusion 33 and the rotation axis of the driving body 21. For example, in some examples, the length direction of the mating groove 221 is set to be perpendicular to the moving direction of the connecting arm 31, that is, the length direction of the mating groove 221 is along the Y-axis.

[0120] When the swing arm 22 is provided with a mating protrusion 33 and the connecting arm 31 is provided with a mating groove 221, since the mating protrusion 33 passes through the avoidance hole 11 and the movement trajectory of the mating protrusion 33 is arc-shaped, in some embodiments, the avoidance hole 11 can be set to match the movement trajectory of the mating protrusion 33, that is, the shape of the avoidance hole 11 is arc-shaped.

[0121] When the swing arm 22 is provided with a mating protrusion 33 and the connecting arm 31 is provided with a mating groove 221, in some embodiments, the mating protrusion 33 can be integrally formed on the swing arm 22 to reduce the number of parts; or, in other embodiments, the mating protrusion 33 can be assembled on the swing arm 22, for example, one end of the mating protrusion 33 can be inserted into the swing arm 22 and tightly fitted on the swing arm 22, or the mating protrusion 33 can be glued to the swing arm 22, etc.

[0122] When the swing arm 22 is provided with a mating protrusion 33 and the connecting arm 31 is provided with a mating groove 221, in some embodiments, the housing 10 includes an upper housing portion 12 disposed above the drive body 21, the upper housing portion 12 is provided with a clearance hole 11, and a water-blocking protrusion 13 is provided on the outer side of the upper housing portion 12, the water-blocking protrusion 13 being disposed around the clearance hole 11.

[0123] When the swing arm 22 is provided with a mating protrusion 33 and the connecting arm 31 is provided with a mating groove 221, in some embodiments, please refer to Figure 20 The drive body 21 includes an upper cover 212, which and the inner side of the housing 10 form an installation cavity 50. The swing arm 22 is disposed in the installation cavity 50. A first sealing member 60 for sealing the two is disposed between the upper cover 212 and the inner side of the housing 10. The first sealing member 60 is disposed around the installation cavity 50.

[0124] When the swing arm 22 is provided with a mating protrusion 33 and the connecting arm 31 is provided with a mating groove 221, in some embodiments, please refer to Figure 20 The housing 10 also includes a lower housing 14 disposed below the drive body 21. The upper cover 212 is provided with a drain hole 2123 that communicates with the mounting cavity 50. The lower housing 14 forms a flow channel 141, one end of which is connected to the drain hole 2123 and the other end is connected to the bottom surface of the lower housing 14.

[0125] Please see Figure 21 , Figure 21 This is a schematic diagram of the structure of the connecting arm 31 provided in some embodiments of this application.

[0126] When the swing arm 22 is provided with a mating protrusion 33 and the connecting arm 31 is provided with a mating groove 221, in some embodiments, please refer to Figure 21 The connecting arm 31 includes an arm body 311 and an annular protrusion 312. The annular protrusion 312 is disposed on the side of the arm body 311 facing the housing 10, and the annular protrusion 312 is used to form a mating groove 221.

[0127] In some examples, annular protrusions 312 may be integrally formed on the arm body 311.

[0128] In some examples, the arm body 311 is provided with a slot that communicates with the annular protrusion 312. The slot and the space enclosed by the annular protrusion 312 together form a mating groove 221, which helps to reduce the thickness of the annular protrusion 312.

[0129] Please see Figure 22 , Figure 22 This is a schematic diagram of the structure of the swing arm 22 provided in some embodiments of this application.

[0130] When the swing arm 22 is provided with a mating protrusion 33 and the connecting arm 31 is provided with a mating groove 221, regarding the shape of the swing arm 22, in some embodiments, the swing arm 22 includes a first arm segment 223 and a second arm segment 224. The first arm segment 223 is located inside the housing 10 and connected to the drive body 21. The second arm segment 224 is connected to the second arm segment 224 and is located inside the housing 10 and directly below the clearance hole 11.

[0131] When the swing arm 22 is provided with a mating protrusion 33 and the connecting arm 31 is provided with a mating groove 221, regarding the shape of the swing arm 22, in other embodiments, the swing arm 22 may be provided with only the first arm segment 223, that is, the swing arm 22 does not include the second arm segment 224.
