[0002] A sweeping robot is a type of intelligent household appliance. It can automatically complete the floor cleaning work in a room by virtue of a certain degree of artificial intelligence. Generally, a sweeping robot can adopt a brushing and vacuuming method to suck ground debris into its own dust collection box, thereby completing the function of ground cleaning. Generally speaking, robots that complete cleaning, dust suction, and mopping work are also uniformly classified as cleaning robots.
[0003] A cleaning robot usually has a sewage tank, a dirt collection trough, a squeegee, and a mopping assembly. The mopping assembly has a mop cloth, and the rotation of the mop cloth realizes the mopping and cleaning of the ground. In order to avoid secondary pollution of the ground by the mopping assembly, when the mop cloth mops the ground, the squeegee contacts the mop cloth to scrape the sewage on the mop cloth into the dirt collection trough and is finally collected in the sewage tank. However, as the use time of the cleaning robot increases, the aging and wear of the squeegee easily cause the squeegee to be disengaged from the mop cloth and fail to scrape the dirt on the mop cloth, affecting the cleaning effect of the cleaning robot.

[0055] 3000a, scraping strip Specific implementation mode
[0056] In order to more clearly understand the above-mentioned objects, features, and advantages of the present application, the solutions of the present application will be further described below. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0057] Many specific details are set forth in the following description in order to provide a thorough understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present application, rather than all the embodiments.
[0058] Embodiment 1
[0059] As Figures 1 to 13 shown, the embodiment of the present application provides a mopping assembly 2000, which is applied to a cleaning robot. The cleaning robot includes a main body base 1000 and a squeegee 3000a disposed on the main body base 1000. The mopping assembly 2000 includes a first bracket 2300, a second bracket 2400, and a mop 2001.
[0060] Wherein, a first rotating shaft 2310 is disposed on the first bracket 2300. The second bracket 2400 includes a main bracket 2400a, a sub-bracket 2400b, and an elastic component. The first bracket 2300 and the main bracket 2400a can be connected to the main body base 1000. A second rotating shaft 2410 parallel to the first rotating shaft 2310 is disposed on the sub-bracket 2400b, and the elastic component is disposed between the main bracket 2400a and the sub-bracket 2400b. The mop 2001 is wound around the first rotating shaft 2310 and the second rotating shaft 2410. The elastic component can provide a driving force for driving the sub-bracket 2400b to move away from the main bracket 2400a, so that the mop 2001 presses tightly against the squeegee 3000a.
[0061] Understandably, by disposing an elastic component between the main bracket 2400a and the sub-bracket 2400b, the elastic component provides a driving force for the sub-bracket 2400b to move away from the main bracket 2400a, so that the mop 2001 presses tightly against the squeegee 3000a. In this way, in the case where the squeegee 3000a is aged or worn, or the mop 2001 is worn, the mop 2001 can still press tightly against the squeegee 3000a under the action of the elastic component, thereby preventing the squeegee 3000a and the mop 2001 from losing contact and losing the scraping effect on the mop 2001, and ensuring the cleaning effect.
[0062] It should be noted that the above-mentioned squeegee strip 3000a provides a resistance force against the movement of the mop 2001, and the direction of the resistance force is opposite to that of the driving force. That is to say, under the action of the elastic component, the mop 2001 can be pressed tightly against the squeegee strip 3000a, and the squeegee strip 3000a provides a resistance force to prevent the mop 2001 from moving. Eventually, the mop 2001 is kept stable under the action of the elastic component of the squeegee strip 3000a and can be pressed tightly against the squeegee strip 3000a so that the squeegee strip 3000a can scrape the dirt on the mop 2001. Or rather, the above-mentioned squeegee strip 3000a abuts against the auxiliary bracket 2400b. In this way, the squeegee strip 3000a can directly apply the resistance force on the auxiliary bracket 2400b, and the auxiliary bracket 2400b is kept stable under the action of the squeegee strip 3000a and the elastic component, so that the mop 2001 is kept in a stable state of pressing tightly against the squeegee strip 3000a.
[0063] Referring to Figure 2 and Figure 3 , the above-mentioned cleaning robot further includes a main body base 1000, a dirt collection box 3000 and the above-mentioned mopping assembly 2000. A component assembly cavity 1000a is formed on the bottom surface of the main body base 1000. The mopping assembly 2000 is detachably installed in the component assembly cavity 1000a. The dirt collection box 3000 is installed on the main body base 1000. One side wall of the dirt collection box 3000 constitutes the squeegee strip 3000a. The squeegee strip 3000a is located on the side of the second bracket 2400 away from the first bracket 2300 in the direction perpendicular to the first rotating shaft 2310. The squeegee strip 3000a abuts against the mop 2001 to scrape the sewage on the mop 2001 into the dirt collection box 3000.
[0064] That is to say, the mopping assembly 2000 can be installed in the component assembly cavity 1000a so that the mop 2001 and the squeegee strip 3000a are in contact. Thus, when the cleaning robot works, the ground can be cleaned by the mop 2001, and the sewage on the mop 2001 can be scraped into the dirt collection box 3000 by the squeegee strip 3000a. The mopping assembly 2000 can also be detached from the component assembly cavity 1000a for maintenance or replacement of the mop 2001.
[0065] Specifically, the above-mentioned dirt collection box 3000 is located at the rear side of the mopping assembly 2000 in the front-back direction of the cleaning robot. The above-mentioned squeegee strip 3000a extends along the width direction of the cleaning robot. Similarly, the width direction of the mop 2001 is the width direction of the cleaning robot. Among them, the width direction of the cleaning robot is perpendicular to its front-back direction, and the cleaning robot can move forward or backward in its front-back direction. Among them, the front-back direction of the cleaning robot is the X direction as shown in Figure 3 , and the width direction of the cleaning robot is the Y direction as shown in Figure 3 .
[0066] Understandably, at this time, both the first rotating shaft 2310 and the second rotating shaft 2410 also extend along the width direction of the cleaning robot, and the first bracket 2300 and the second bracket 2400 are spaced apart in the front-rear direction of the cleaning robot.
[0067] Referring to Figures 4 to 13 , the elastic component includes a pressing elastic member 2700. The mopping component 2000 further includes a connecting and limiting member 2900. The connecting and limiting member 2900 is disposed between the main bracket 2400a and the sub-bracket 2400b, and the pressing elastic member 2700 abuts between the main bracket 2400a and the sub-bracket 2400b.
[0068] Understandably, the connecting and limiting member 2900 is used to limit the movement of the sub-bracket 2400b relative to the main bracket 2400a, so that the sub-bracket 2400b moves in the driving force direction of the elastic component, that is, in the direction of the squeegee 3000a, and avoids deviating from the squeegee 3000a.
[0069] Specifically, the connecting and limiting member 2900 may be a chute provided on one of the sub-bracket 2400b and the main bracket 2400a, and a slide rail provided on the other. The slide rail can move along the chute, and its moving direction is the direction facing the squeegee 3000a. The connecting and limiting member 2900 may also be a limiting post provided on one of the sub-bracket 2400b and the main bracket 2400a, and a through hole provided on the other. The limiting post can move in the through hole, and its moving direction is the direction facing the squeegee 3000a.
[0070] Furthermore, the axial direction of the connecting and limiting member 2900 is perpendicular to the axial direction of the first rotating shaft 2310. Since the connecting and limiting member 2900 passes through the main bracket 2400a and is connected to the sub-bracket 2400b, the connecting and limiting member 2900 and the sub-bracket 2400b are connected as a whole and move relative to the main bracket 2400a. At this time, the connecting and limiting member 2900 plays a guiding and limiting role, that is, guiding the relative movement of the sub-bracket 2400b and the main bracket 2400a, and limiting the pressing elastic member 2700 to prevent the pressing elastic member 2700 from shifting and affecting the direction of the force applied to the sub-bracket 2400b.
[0071] It should be noted that the above-mentioned pressing elastic member 2700 is always in a compressed state. In this way, the elastic force of the pressing elastic member 2700 itself will act on the sub-bracket 2400b and the main bracket 2400a. Since the main bracket 2400a is connected to the first bracket 2300, and the sub-bracket 2400b can move relative to the main bracket 2400a through the connecting and limiting member 2900, a force can be applied to the mop 2001 through the sub-bracket 2400b all the time, so that the mop 2001 can always be in contact with the squeegee 3000a.
[0072] Further, the connecting limiting member 2900 is inserted through the main bracket 2400a and can move in its own axial direction. A through hole for the connecting limiting member 2900 to pass through is formed on the main bracket 2400a. A limiting post protrudes from the sub-bracket 2400b. The pressing elastic member 2700 is sleeved on the limiting post, and the connecting limiting member 2900 is connected to the limiting post.
[0073] Understandably, by providing the through hole, the movement of the connecting limiting member 2900 can be guided and limited. The limiting post cooperates with the connecting limiting member 2900 to limit the pressing elastic member 2700 and guide the compression of the pressing elastic member 2700, so as to ensure that the movement of the sub-bracket 2400b relative to the main bracket 2400a always remains in the required specific direction, that is, the axial direction of the connecting limiting member 2900.
[0074] Exemplarily, in a specific implementation manner, the above-mentioned connecting limiting member 2900 is preferably a bolt. The rod portion of the bolt is inserted through the through hole and is threadedly connected to the limiting post. The threaded connection between the connecting limiting member 2900 and the limiting post is convenient for installation and disassembly. Moreover, the head of the bolt can also limit the movement of the bolt to prevent the bolt from completely passing out of the through hole and causing the sub-bracket 2400b and the main bracket 2400a to be disengaged.
[0075] Optionally, it can also be that a limiting post protrudes from the sub-bracket, the pressing elastic member is sleeved on the limiting post, a through hole for the limiting post to pass through is formed on the main bracket, and the connecting limiting member is connected to the limiting post. At this time, the limiting post guides and limits the pressing elastic member, and the connecting limiting member limits the limiting post to prevent the limiting post from coming out of the through hole.
[0076] To ensure the stability of the movement of the sub-bracket 2400b relative to the main bracket 2400a, at least two of the above-mentioned connecting limiting members 2900 are provided. The at least two connecting limiting members 2900 are arranged at intervals along the axial direction of the second rotating shaft 2410. The pressing elastic members 2700 are sleeved on the at least two connecting limiting members 2900, and two of the pressing elastic members 2700 are symmetrically arranged.
[0077] That is to say, the movement of the sub-bracket 2400b relative to the main bracket 2400a is limited by at least two connecting limiting members 2900, and the stability of the overall movement of the sub-bracket 2400b is ensured by two pressing elastic members 2700 symmetrically arranged in the extending direction of the second rotating shaft 2410, so as to prevent the situation that the distances of the two ends of the sub-bracket 2400b relative to the main bracket 2400a in the extending direction of the second rotating shaft 2410 are different and cause the mopping cloth 2001 to be skewed.
[0078] Exemplarily, referring to Figures 4 to 13, the above-mentioned auxiliary bracket 2400b includes two bracket bodies, and both ends of the second rotating shaft 2410 are rotatably arranged on the two bracket bodies, and a supporting elastic member 2500 is arranged between each bracket body and the main bracket 2400a.
[0079] That is to say, at this time, two supporting elastic members 2500 are provided so that both bracket bodies can move relative to the main bracket 2400a. By setting the auxiliary bracket 2400b as two bracket bodies, the weight of the auxiliary bracket 2400b can be reduced, and thus the weight of the mopping assembly 2000 can be reduced.
[0080] Refer to again Figures 4 to 13 , the auxiliary bracket 2400b and the main bracket 2400a are in contact in the initial state, that is to say, at this time, there is no relative movement between the auxiliary bracket 2400b and the main bracket 2400a. As shown in Figures 4 to 8 , it can be considered that at this time, the scraping strip 3000a has not been worn or aged. After the mopping assembly 2000 is normally installed in the assembly cavity 1000a, the scraping strip 3000a and the mop 2001 are tightly pressed. As the scraping strip 3000a and the mop 2001 are used, the scraping strip 3000a or the mop 2001 will be worn and aged. If the position of the mop 2001 remains unchanged, a gap will appear between the mop 2001 and the scraping strip 3000a, that is, the mop 2001 and the scraping strip 3000a will be out of contact. In this way, the scraping strip 3000a will lose its scraping effect on the mop 2001. Through the setting of the pressing elastic member 2700, the pressing elastic member 2700 can apply a force to the auxiliary bracket 2400b, so that the auxiliary bracket 2400b always has a tendency to move away from the main bracket 2400a. Thus, under the drive of the auxiliary bracket 2400b, the mop 2001 can be pushed to be tightened and always pressed against the scraping strip 3000a. Therefore, after the scraping strip 3000a is used for a period of time, the auxiliary bracket 2400b moves relative to the main bracket 2400a, resulting in a gap h between the two, as shown in Figures 8 to 13 . However, at this time, the mop 2001 is tightened under the action of the pressing elastic member 2700 and the auxiliary bracket 2400b and still presses against the scraping strip 3000a, so that the scraping strip 3000a can still scrape the mop 2001, which can increase the service life of the scraping strip 3000a, reduce the replacement times of the scraping strip 3000a, and reduce the cleaning cost.
[0081] Embodiment 2
[0082] As shown in Figure 14 and Figure 15As shown in the figure, this embodiment provides a cleaning robot, which includes the mopping component 2000 in Embodiment 1. Among them, the main bracket 2400a is movably connected to the first bracket 2300. Moreover, the mopping component 2000 in this embodiment further includes a support elastic member 2500 and a clamping element 2200. Among them, the support elastic member 2500 is disposed between the main bracket 2400a and the first bracket 2300, and the clamping element 2200 is disposed on the first bracket 2300 and has a locking position and an unlocking position relative to the first bracket 2300. The first bracket 2300 and the main bracket 2400a have an expanded state and a collapsed state. When the first bracket 2300 and the main bracket 2400a are in the collapsed state, the clamping element 2200 is in the locking position and is clamped to the main bracket 2400a, and the support elastic member 2500 is in a compressed state. When the clamping element 2200 moves from the locking position to the unlocking position, the clamping element 2200 and the main bracket 2400a are disengaged from the clamping connection.
[0083] Further, the above mopping component 2000 further includes a reset element 2100, and the reset element 2100 is disposed on the main bracket 2400a. When the first bracket 2300 and the main bracket 2400a are in the collapsed state, the reset element 2100 can drive the clamping element 2200 to move from the locking position to the unlocking position. When the first bracket 2300 and the main bracket 2400a are in the expanded state, the reset element 2100 is used to be clamped and matched with the clamping element 1100 on the host base 1000. That is to say, the main bracket 2400a is connected to the host base 1000 through the reset element 2100.
[0084] Specifically, a component assembly cavity 1000a is opened on the bottom surface of the host base 1000 of the cleaning robot. The component assembly cavity 1000a can be adapted to the shape and size of the mopping component 2000, so that the mopping component 2000 can be detachably installed in the component assembly cavity 1000a. When work is needed, the mopping component 2000 is installed in the component assembly cavity 1000a, and when replacement or cleaning is required, the mopping component 2000 can be detached from the component assembly cavity 1000a.
[0085] In addition, the above-mentioned clamping element 1100 is also provided on the host base 1000, and the clamping element 1100 can be used to cooperate with the mopping assembly 2000 for assembly. Among them, the above-mentioned reset element 2100 is elastically assembled on the mopping assembly 2000. The reset element 2100 has a first reset state and a second reset state. After the reset element 2100 is assembled on the mopping assembly 2000, the first reset state and the second reset state represent different installation states formed on the main bracket 2400a, including but not limited to different positions, different angles, different forms, etc. of the reset element 2100 on the main bracket 2400a. This is not limited here. Those skilled in the art can construct different installation states of the reset element 2100 on the main bracket 2400a according to actual assembly or functional requirements to construct the first reset state and the second reset state that can achieve specific functions or effects.
[0086] Referring to Figures 14 to 20 , the clamping element 2200 is elastically assembled on the first bracket 2300. The first bracket 2300 and the main bracket 2400a have an expanded state and a collapsed state. The expanded state represents the state where the size of the mopping assembly 2000 becomes larger, and the collapsed state represents the state where the size of the mopping assembly 2000 becomes smaller. For example, when the first bracket 2300 and the main bracket 2400a are put together, causing the size of the mopping assembly 2000 to become smaller, it means that the first bracket 2300 and the main bracket 2400a are in the collapsed state at this time. On the contrary, when the first bracket 2300 and the main bracket 2400a are separated from each other, causing the size of the mopping assembly 2000 to become larger, it means that the first bracket 2300 and the main bracket 2400a are in the expanded state at this time.
[0087] Referring to Figure 16 and Figure 17 , when the mopping assembly 2000 is in the expanded state, the clamping element 2200 is disengaged from the alignment with the reset element 2100. At this time, the reset element 2100 is in the first reset state. For example, the reset element 2100 is in a specific position or a specific area on the mopping assembly 2000. In this first reset state, the reset element 2100 can be used to engage and cooperate with the clamping element 1100 on the host base 1000. That is, when the mopping assembly 2000 is assembled in the component assembly cavity 1000a of the host base 1000 at this time, the reset element 2100 can form an engaging and cooperating relationship with the clamping element 1100 of the host base 1000 in the first reset state, adapting to the assembly between the mopping assembly 2000 and the host base 1000.
[0088] Referring to Figure 18 and Figure 19When the mopping assembly 2000 is in the folded state, the resetting element 2100 switches from the first resetting state to the second resetting state. For example, the resetting element 2100 is now in another specific position or another specific area on the main bracket 2400a. The change in position of the resetting element 2100 can cause the resetting element 2100 to switch from the first resetting state to the second resetting state. In this state, the clamping element 2200 can be aligned with the resetting element 2100, so that the first bracket 2300 and the main bracket 2400a remain in the folded state, so that the first bracket 2300 and the main bracket 2400a provide a stable state for easy installation of the mop 2001 in the folded state.
[0089] The main support 2400a is provided with a reset assembly channel 2000a, and the reset element 2100 is elastically assembled in the reset assembly channel 2000a. Figure 20 As shown, the reset assembly channel 2000a is Figure 20 The channel opened on the main bracket 2400a toward the extension direction of the second rotating shaft 2410, the reset assembly channel 2000a may not be a channel form that is closed on all sides. When the reset element 2100 is in the first reset state, a part of it is exposed in the reset assembly channel 2000a, and the part of the reset element 2100 exposed in the reset assembly channel 2000a can be used for the clamping element 1100 to engage. Alternatively, the mopping assembly 2000 is provided with a reset assembly channel 2000a, the reset element 2100 is elastically assembled in the reset assembly channel 2000a, and the exposed length of the reset element 2100 relative to the reset assembly channel 2000a in the first reset state is less than the exposed length of the reset element 2100 in the second reset state.
[0090] As can be seen from the above, the cleaning robot provides two state changes of the first bracket 2300 and the main bracket 2400a, namely, the expanded state and the collapsed state, in terms of structural design, and based on the two change states of the mopping component 2000, two state changes of the reset element 2100 are designed in linkage. In this way, the mopping component 2000 can conveniently realize the installation and removal of the mop 2001, and can also be conveniently installed and removed relative to the main base 1000. Among them, the first bracket 2300 and the main bracket 2400a can reduce their own structural dimensions in the folded state, providing convenient structural deformation for the installation of the mop 2001. The mop 2001 can be more conveniently wound around the first rotating shaft 2310 and the second rotating shaft 2410 when the first bracket 2300 and the main bracket 2400a are in the folded state. When the mop 2001 is installed, the first bracket 2300 and the main bracket 2400a can be converted to the expanded state, and the installed mop 2001 is expanded, so that the mop 2001 is tensioned on the first bracket 2300 and the second bracket 2400.
[0091] Moreover, when the first bracket 2300 and the main bracket 2400a are in the folded state, the reset element 2100 can be linked to be in the second reset state, so that the snap-in element 2200 can be aligned with the reset element 2100, and the alignment and cooperation between the snap-in element 2200 and the reset element 2100 can keep the first bracket 2300 and the main bracket 2400a in the folded state, thereby facilitating the installation of the mop 2001.
[0092] After the mop 2001 is installed, when the first bracket 2300 and the main bracket 2400a are in the expanded state, the reset element 2100 can be linked to be in the first reset state, so that the clamping element 2200 and the reset element 2100 are out of alignment. At this time, the mopping component 2000 can be assembled in the component assembly cavity 1000a of the main unit base 1000. Therefore, the reset element 2100 is automatically in the first reset state at this time, and can be directly used for clamping and matching with the clamping element 1100 of the main unit base 1000, so as to be suitable for the assembly between the mopping component 2000 and the main unit base 1000, and the mutual clamping and matching between the reset element 2100 and the clamping element 1100 makes the mopping component 2000 and the main unit base 1000 form a more secure assembly.
[0093] Reference Figures 16 to 20 A first plug-in component 2320 may be provided on the first bracket 2300, and a second plug-in component 2420 may be provided on the main bracket 2400a. The first bracket 2300 is plugged into and matched with the second plug-in component 2420 of the main bracket 2400a through the first plug-in component 2320. When the first bracket 2300 and the main bracket 2400a are put together, the mutual plug-in between the first plug-in component 2320 and the second plug-in component 2420 is utilized to ensure the stability of the first bracket 2300 and the main bracket 2400a when they are in the folded state.
[0094] The first bracket 2300 may be provided with a first limiting component 2330, and the main bracket 2400a may be provided with a second limiting component 2430. The first bracket 2300 and the second limiting component 2430 of the main bracket 2400a are mutually limited by the first limiting component 2330, so that the first bracket 2300 and the main bracket 2400a can be separated and put together along the limiting track of the first limiting component 2330 and the second limiting component 2430, thereby ensuring the smoothness of the conversion of the first bracket 2300 and the main bracket 2400a between the expanded state and the collapsed state.
[0095] Further, a supporting elastic member 2500 is provided between the first bracket 2300 and the main bracket 2400a, and the supporting elastic member 2500 can apply an elastic force between the first bracket 2300 and the main bracket 2400a, and the first bracket 2300 and the main bracket 2400a can be separated from each other and be in an open state by the elastic force of the supporting elastic member 2500. Therefore, when the elastic force of the supporting elastic member 2500 is overcome, the first bracket 2300 and the main bracket 2400a can be matched with each other. For example, when the first bracket 2300 and the main bracket 2400a are in the folded state, the reset element 2100 is in the second reset state, so that the clamping element 2200 can be aligned with the reset element 2100, and the alignment between the two overcomes the elastic force of the supporting elastic member 2500, thereby maintaining the folded state of the first bracket 2300 and the main bracket 2400a, and facilitating the stable installation of the mop 2001 in this state.
[0096] Reference Figures 16 to 20 The reset element 2100 can be elastically assembled on the main support 2400a. The main support 2400a is provided with a reset assembly channel 2000a. The reset element 2100 is elastically assembled in the reset assembly channel 2000a. The reset element 2100 can be elastically assembled in the reset assembly channel 2000a through the first elastic element 2100a. The first elastic element 2100a can apply an elastic force between the reset element 2100 and the main support 2400a, so that the reset element 2100 is maintained in the first reset state and the second reset state by the elastic force of the first elastic element 2100a.
[0097] Furthermore, the clamping element 2200 can be used to clamp and cooperate with the main bracket 2400a, so that the first bracket 2300 and the main bracket 2400a are combined with each other, so that the first bracket 2300 and the main bracket 2400a are in a folded state. Among them, the clamping element 2200 can also be elastically assembled on the first bracket 2300, and the clamping element 2200 can be provided with a clamping guide part 2200a, referring to Figure 22 The clamping guide portion 2200a is used to cooperate with the main bracket 2400a for sliding guidance, so as to slide and guide the clamping element 2200 into the reset assembly channel 2000a, thereby realizing the alignment between the clamping element 2200 and the reset element 2100.
[0098] Regarding the elastic assembly of the clamping element 2200, a locking position and an unlocking position may be set on the first bracket 2300, and the clamping element 2200 may elastically move between the locking position and the unlocking position. The first bracket 2300 is provided with a clamping assembly channel 2000b, and the clamping element 2200 is elastically assembled in the clamping assembly channel 2000b through the second elastic element 2200b, and the clamping element 2200 is elastically maintained in the locking position of the first bracket 2300 through the second elastic element 2200b.Figure 20 As shown, the snap - fitting assembly channel 2000b is a channel opened by the first bracket 2300 towards the main bracket 2400a, and the snap - fitting assembly channel 2000b may not be in the form of a channel closed on all sides.
[0099] After the snap - fitting element 2200 slides into the reset assembly channel 2000a through the snap - fitting guiding part 2200a, the snap - fitting element 2200 can make the first bracket 2300 and the main bracket 2400a merge with each other through snap - fitting with respect to the reset assembly channel 2000a, overcoming the elastic force of the support elastic element 2500, resulting in the first bracket 2300 and the main bracket 2400a being in a closed state. Among them, referring to Figure 14 and Figure 15 , the positioning element 1100 has a positioning through - hole 1100a, and the reset element 2100 is used for snap - fitting with the positioning through - hole 1100a of the positioning element 1100.
[0100] Specifically, referring to Figure 22 , the above - mentioned snap - fitting guiding part 2200a has a guiding inclined surface. When the first bracket 2300 and the main bracket 2400a are forced to approach each other, the support elastic element 2500 is compressed. When the snap - fitting guiding part 2200a contacts the main bracket 2400a through the guiding inclined surface, the snap - fitting element 2200 is subjected to a force in the extending direction of the first rotating shaft 2310 and compresses the second elastic element 2200b, so that the snap - fitting element 2200 moves from the locking position to the unlocking position. When the snap - fitting assembly channel 2000b and the reset assembly channel 2000a are connected, the snap - fitting element 2200 loses the force acting on it from the main bracket 2400a, and under the action of the second elastic element 2200b, it moves from the unlocking position to the locking position. At this time, the snap - fitting element 2200 partially extends into the reset assembly channel 2000a.
[0101] Referring to Figures 16 to 20 and Figure 21 , the reset element 2100 has a reset guiding part 2100b, and the reset guiding part 2100b is used for sliding guiding cooperation with the positioning element 1100 to slide the reset element 2100 into the positioning through - hole 1100a. Among them, the reset guiding part 2100b can be set as an inclined - surface structure located on the reset element 2100. The inclined - surface structure can slide - guide cooperate with the positioning element 1100 by setting an appropriate inclined - surface angle. When the reset element 2100 contacts the positioning element 1100 through the reset guiding part 2100b constructed on it, the reset guiding part 2100b can slide - guide cooperate with the positioning element 1100 along the appropriate inclined - surface angle to slide - guide the reset element 2100 into the positioning through - hole 1100a.
[0102] When the first bracket 2300 and the main bracket 2400a are in the closed state, the above-mentioned snap-fit assembly channel 2000b is in communication with the reset assembly channel 2000a, allowing at least a part of the snap-fit element 2200 to enter the reset assembly channel 2000a, and then being in alignment and cooperation with the reset element 2100. Therefore, when the first bracket 2300 and the main bracket 2400a change from the open state to the closed state, the snap-fit assembly channel 2000b can first be in communication with the reset assembly channel 2000a. At this time, the snap-fit element 2200 can slide into the reset assembly channel 2000a, and the snap-fit element 2200 can be in snap-fit with the reset assembly channel 2000a, causing the first bracket 2300 and the main bracket 2400a to merge with each other, overcoming the elastic force of the support elastic member 2500, so that the first bracket 2300 and the main bracket 2400a are in the closed state.
[0103] When the reset element 2100 is in the second reset state, the reset element 2100 in the second reset state can be used to drive the snap-fit element 2200 away from the first bracket 2300, separating the first bracket 2300 from the main bracket 2400a, and causing the first bracket 2300 and the main bracket 2400a to switch from the closed state to the open state. For example, if the reset element 2100 is driven to move towards the snap-fit element 2200, the reset element 2100 can come into contact with the snap-fit element 2200. After a certain force is applied to the snap-fit element 2200 by the reset element 2100, the snap-fit element 2200 can slip out of the reset assembly channel 2000a under the drive of the reset element 2100, releasing the snap-fit between the snap-fit element 2200 and the reset element 2100. After the snap-fit between the snap-fit element 2200 and the reset element 2100 is eliminated, the first bracket 2300 and the main bracket 2400a can continue to be separated from each other under the elastic force of the support elastic member 2500, so that the first bracket 2300 and the main bracket 2400a are in the open state.
[0104] Refer to Figure 14 、 Figure 15 and Figure 20, a positioning groove 1000b and a driving positioning cavity 1000c are provided on the host base 1000. The mopping assembly 2000 further includes a positioning assembly 2600 and a driving assembly 2800. The positioning assembly 2600 can be arranged on the first bracket 2300 or the second bracket 2400, and the driving assembly 2800 can also be arranged on the first bracket 2300 or the second bracket 2400. Among them, the positioning groove 1000b is used to cooperate with the positioning assembly 2600, so that the mopping assembly 2000 can be assembled in the component assembly cavity 1000a of the host base 1000 through the positioning assembly between the positioning assembly 2600 and the positioning groove 1000b. The driving positioning cavity 1000c is used to cooperate with the driving assembly 2800, so that the mopping assembly 2000 can form a driving assembly through the driving assembly 2800 and the driving positioning cavity 1000c, and the driving assembly 2800 is driven and connected to the driving motor arranged inside the host base 1000 by using the driving positioning cavity 1000c, and the driving motor drives the first rotating shaft 2310 to rotate through the driving assembly 2800.
[0105] For example, the positioning groove 1000b and the driving positioning cavity 1000c are symmetrically arranged on the left and right sides of the component assembly cavity 1000a, and the positioning assembly 2600 and the driving assembly 2800 are also symmetrically arranged on the left and right sides of the mopping assembly 2000. When installing the mopping assembly 2000, the driving assembly 2800 can be first driven and docked in the driving positioning cavity 1000c, and then the positioning assembly 2600 can be docked in the positioning groove 1000b. At this time, referring to Figure 15 shown, the entire mopping assembly 2000 can be rotated axially along the first rotating shaft 2310, that is Figure 15 the counterclockwise rotation in. Among them, the positioning assembly 2600 will also rotate in the positioning groove 1000b. At this time, after the positioning assembly 2600 rotates relative to the positioning groove 1000b, the positioning assembly 2600 can be locked in the positioning groove 1000b.
[0106] For example, in the shape design of the positioning groove 1000b and the positioning assembly 2600, the positioning assembly 2600 can be designed as a square body. The positioning groove 1000b includes a groove part that can accommodate the square positioning assembly 2600. When the square positioning assembly 2600 enters the positioning groove 1000b along this groove part, the positioning groove 1000b also includes a groove part that can lock the square positioning assembly 2600 after rotation, so that the positioning assembly 2600 can be locked in the positioning groove 1000b after rotating relative to the positioning groove 1000b. In addition, those skilled in the art can also realize the locking of the positioning assembly 2600 in the positioning groove 1000b after rotation through other design solutions, which will not be limited here.
[0107] Embodiment III
[0108] This embodiment provides a mopping component. The structure of this mopping component is basically the same as that of the mopping component in the first embodiment, except that: in this embodiment, the first bracket and the main bracket of the mopping component are rotatably connected, so that the first bracket and the main bracket have an expanded state and a folded state.
[0109] Among them, the expanded state means that the first bracket and the main bracket are on the same plane, or the angle between the first bracket and the second bracket is 180°. The folded state means that under the action of an external force, the first bracket and the main bracket rotate relative to each other and the angle between the first bracket and the main bracket gradually becomes smaller.
[0110] In this way, when the first bracket and the main bracket are in the expanded state, the mopping cloth wound around the first rotating shaft and the second rotating shaft is tensioned. When the first bracket and the main bracket are in the folded state, the mopping cloth wound around the first rotating shaft and the second rotating shaft is slack. In this way, when the mopping cloth needs to be disassembled, the mopping cloth bracket is adjusted to the folded state, and when the mopping cloth component is set vertically, the mopping cloth can fall under its own gravity without the user's manual assistance in disassembling the mopping cloth. Similarly, when the mopping cloth needs to be installed, the first bracket and the main bracket are adjusted to the folded state, the mopping cloth is wound around the first rotating shaft and the second rotating shaft, and then the first bracket and the main bracket are adjusted to the expanded state, and the mopping cloth is tensioned to complete the installation of the mopping cloth.
[0111] It should be noted that the above mopping component can also be provided with a reset elastic member. In a specific implementation manner, when the first bracket and the main bracket are in the folded state and not affected by an external force, the reset elastic member can drive the first bracket and the main bracket to be adjusted to the expanded state. At this time, the reset elastic member can be selected as a torsion spring. The torsion spring is sleeved on the rotating shaft of the first bracket and the main bracket. One of the two free ends of the torsion spring abuts against the first bracket, and the other abuts against the main bracket. When the first bracket and the main bracket are folded, the torsion spring is stressed and outputs elastic force. When the first bracket and the main bracket are in the folded state and not affected by an external force, the torsion spring drives the first bracket and the second self-driving to rotate relative to each other and expand.
[0112] In another specific implementation manner, when the first bracket and the main bracket are in the expanded state and not affected by an external force, the reset elastic member can drive the first bracket and the main bracket to be adjusted to the folded state. At this time, the reset elastic member can be selected as a tension spring. One end of the tension spring is connected to the first bracket, and the other end is connected to the main bracket. When the first bracket and the main bracket are in the folded state, the tension spring is in an unstressed state. When the first bracket and the main bracket change from the folded state to the expanded state, the tension spring is stretched and stores elastic potential energy.
[0113] This embodiment further provides a cleaning robot, which includes a main body base, a dirt collection box, and the above-mentioned mopping assembly. A component assembly cavity is formed on the bottom surface of the main body base. The mopping assembly is detachably installed in the component assembly cavity. The dirt collection box is installed on the main body base. One side wall of the dirt collection box forms a scraping strip. The scraping strip is located on the side of the second bracket away from the first bracket in the direction perpendicular to the first rotating shaft. The scraping strip abuts against the mop to scrape the sewage on the mop into the dirt collection box.
[0114] It should be noted that in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitations, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.
[0115] The above are only specific embodiments of the present application, enabling those skilled in the art to understand or implement the present application. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments described herein, but rather will be accorded the widest scope consistent with the principles and novel features disclosed herein.
