Description

Technical Field

[0001] This utility model relates to the field of cleaning technology, specifically to a lifting component, a cleaning module, and a cleaning device. Background Technology

[0002] With the development of the social economy and the improvement of family living standards, home cleaning equipment has gradually entered the era of intelligence and mechanization. Among them, cleaning robots are the most common. Cleaning robots can effectively reduce people's workload in home cleaning, freeing them from heavy housework and improving their quality of life.

[0003] Existing cleaning robots have various cleaning components with different structures, such as mop trays, cleaning rollers, and cleaning brushes. However, regardless of the type of cleaning component, it needs to be in close contact with the ground when cleaning. When encountering obstacles, the cleaning component needs to be raised to avoid them. For example, a cleaning module and sweeping robot disclosed in patent announcement number CN221533636U uses a damping component to provide damping force to the second sleeve, creating a speed difference between the first and second sleeves. This allows the first sleeve to rise and fall relative to the second sleeve and the drive component, thereby raising and lowering the cleaning component. However, during the driving process, the lifting stroke of the cleaning component is not directly driven by the drive component. The lifting stroke of the cleaning component is also affected by the magnitude of the damping force of the damping component on the second sleeve. This causes the drive component to be unable to accurately control the lifting stroke of the cleaning component. Moreover, since the cleaning component is inserted inside the first sleeve, there is no space reserved for a positioning detection component, which makes it impossible to detect whether the cleaning component has risen to the correct position in time. This often results in the cleaning component not rising to the correct position, affecting the obstacle avoidance capability of the cleaning component. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a lifting component, a cleaning module, and a cleaning device.

[0005] The cleaning mechanism disclosed in this application includes: a trigger and a lifting member, an active member, and a guide member arranged sequentially from the inside to the outside. The guide member is movably connected to the lifting member in the lifting direction to guide the lifting member to rise and fall. The active member is configured to drive the lifting member to rise and fall. The trigger member is located outside the guide member and is either away from or in contact with the lifting member. The active member drives the lifting member to rise by rotating. The rising lifting member abuts against the trigger member and drives the trigger member to rise to the designated trigger height.

[0006] Preferably, the lifting component has a mating part on its surface, the driving component has a spiral groove, the mating part slides in the spiral groove, the guide component has a clearance hole, and the trigger component has a connecting part located in the clearance hole; The active component drives the lifting component to rise by rotation. The lifting component rises and drives the mating part to rise synchronously. The mating part rises and extends into the clearance hole to abut against the connecting part. The mating part rises and drives the connecting part and the trigger component to move to the triggering height.

[0007] Preferably, the guide member is provided with a guide groove along the upward path direction of the mating part, the guide groove is connected to the avoidance hole, and the end of the mating part away from the lifting member is slidably disposed in the guide groove or the avoidance hole.

[0008] Preferably, one of the lifting component and the guide component is provided with a guide groove, and the other of the guide component and the lifting component is provided with a guide part corresponding to the position of the guide groove. The guide part slides in the guide groove and guides the lifting of the lifting component.

[0009] Preferably, the triggering element includes a triggering part and an elastic part. The triggering part is located outside the guide and is away from or in contact with the lifting element. The elastic part is located on the upper or lower surface of the triggering part.

[0010] Preferably, the triggering part includes a trigger ring and a connecting part disposed on the trigger ring, the elastic part is disposed on the upper or lower surface of the trigger ring, the trigger ring is sleeved on the outside of the guide member, and the connecting part is either away from or abuts against the lifting member.

[0011] Preferably, the lifting assembly further includes a housing and a detection component. The guide and trigger are both located inside the housing, and the detection component is installed in the housing. The driving component drives the lifting component to rise by rotation. The rising lifting component comes into contact with the trigger and drives the trigger to rise to the designated trigger height. When the trigger reaches the designated trigger height, it triggers the detection component.

[0012] Preferably, one of the driving member and the lifting member is provided with a spiral groove, and the other of the lifting member and the driving member is provided with a mating part corresponding to the position of the spiral groove, and the mating part is slidably disposed in the spiral groove.

[0013] This application also discloses a cleaning module, including a drive component and a lifting component, with the active component connected to the power output end of the drive component.

[0014] This application also discloses a cleaning device, including a body and a cleaning module, with a drive component installed on the body.

[0015] The beneficial effects of this application are as follows: the drive component drives the active component to rotate, the rotation of the active component causes the lifting component to descend relative to the active component, and the descent of the lifting component causes the cleaning component to descend and come into close contact with the ground for cleaning operations. When an obstacle is encountered, the drive component drives the active component to rotate in the opposite direction, the reverse rotation of the active component causes the lifting component to rise relative to the active component, and the rise of the lifting component causes the cleaning component to rise and move away from the ground, thereby avoiding collision between the cleaning component and the obstacle and achieving obstacle avoidance. During the rising process of the lifting component, the rising of the lifting component will push the trigger component to rise to the designated trigger height. When the detection component detects that the trigger component has risen to the designated trigger height, the trigger component will move to the designated trigger height. This means that the drive assembly can be controlled to stop driving the active component to rotate in the opposite direction, and the lifting and cleaning components will stop rising. It can be understood that when the trigger rises to the trigger height, it means that the lifting height of the cleaning component has been reached. In other words, by setting the detection component and the trigger, the lifting height of the cleaning component is detected, ensuring that the drive assembly stops when the cleaning component is lifted to the correct height. This avoids the cleaning component from colliding or scraping with obstacles, reduces energy consumption, and also avoids the situation where the drive assembly continues to drive when the lifting component has reached its limit position, thereby avoiding the problem of drive assembly stalling and extending the service life of the drive assembly.

[0018] The following drawings disclose several embodiments of this application. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this application. That is, in some embodiments of this application, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0019] It should be noted that all directional indications in the embodiments of this application, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0020] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit this application. They are merely used to distinguish components or operations described using the same technical terms and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0021] To further understand the content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0022] Example 1: Reference Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the lifting component in the embodiment. Figure 2 The diagram shows a cross-sectional view of the lifting assembly in this embodiment. The lifting assembly includes a trigger element 1 and, from the inside out, a lifting element 2, an active element 3, and a guide element 4, sequentially nested together. The guide element 4 is movably connected to the lifting element 2 in the lifting direction to guide the lifting element 2 to rise and fall. The active element 3 is configured to drive the lifting element 2 to rise and fall. The trigger element 1 is located outside the guide element 4 and is either away from or in contact with the lifting element 2. The active element 3 drives the lifting element 2 to rise by rotation. The rising lifting element 2 abuts against the trigger element 1 and drives the trigger element 1 to rise to the designated trigger height.

[0023] In this embodiment, the lifting component is applied to the cleaning module. The lifting member 2 is connected to the cleaning module, thereby driving the cleaning module to lift, rotate, and move. Specifically, the cleaning module also includes a drive component 7, and an active member 3 is connected to the power output end of the drive component 7. The drive component 7 drives the active member 3 to rotate, and the rotation of the active member 3 drives the lifting member 2 to lift and move. The lifting member 2 lifts and moves, driving the cleaning module to lift and move. The guide member 4 guides the lifting and moving of the lifting member 2. In specific applications, the drive component 7 drives the active member 3 to rotate forward, and the forward rotation of the active member 3 drives the lifting member 2 to descend. The descent of the lifting member 2 causes the cleaning module to descend and come into close contact with the ground for cleaning operations. When an obstacle is encountered, the drive assembly 7 drives the active component 3 to rotate in the opposite direction. This rotation of the active component 3 causes the lifting component 2 to rise, which in turn raises the cleaning component and lifts it away from the ground. Simultaneously, the rising of the lifting component 2 causes the trigger component 1 to rise. When the trigger component 1 reaches its designated trigger height, it indicates that the lifting component 2 has reached its designated height, meaning the cleaning component has reached the correct lifting height. This prevents the cleaning component from colliding with the obstacle, thus achieving obstacle avoidance. Furthermore, when the trigger component 1 reaches its designated trigger height, the drive assembly 7 stops driving the active component 3 to rotate, meaning the lifting component 2 stops rising, preventing the cleaning component from over-rising and improving stability. Specifically, the cleaning component can be a cleaning part such as a mop pad or cleaning brush that performs cleaning operations through rotation. This is not a limitation; the forward and reverse rotations in this embodiment are only used to distinguish the direction of rotation for clarity and do not limit the specific scope of protection.

[0024] Rereference Figure 2 Preferably, the lifting assembly further includes a housing 5 and a detection element 6. The guide element 4 and the trigger element 1 are both located within the housing 5, and the detection element 6 is mounted on the housing 5. The driving element 3 drives the lifting element 2 to rise by rotation. The rising lifting element 2 abuts against the trigger element 1 and drives the trigger element 1 to rise to the designated trigger height. When the trigger element 1 reaches the designated trigger height, it triggers the detection element 6. In a specific application, the drive assembly 7 includes a drive motor 71 and a reduction mechanism 72. The reduction mechanism 72 is located within the housing 5, and the driving element 3 is rotatably located within the housing 5. The drive end of the drive motor 71 is connected to the reduction mechanism 72, and the output shaft of the reduction mechanism 72 is connected to the driving element 3. The driving element 3 is sleeved outside the lifting element 2, and the drive motor 71 is electrically connected to the detection element 6. The drive motor 71 drives the driving element 3 to rotate through the reduction mechanism 72, and the rotation of the driving element 3 drives the lifting element 2 to rise and fall. Specifically, the detection component 6 is a photoelectric sensor. When the trigger component 1 rises to the trigger height, that is, when it enters the detection area of ​​the photoelectric sensor, the photoelectric sensor is triggered. At this time, the photoelectric sensor senses that the lifting component 2 and the cleaning component have been raised to the correct position, and controls the drive motor 71 to stop driving.

[0025] Reference Figures 3-5 , Figure 3 This is a schematic diagram of the transmission sleeve and lifting component in the embodiment. Figure 4 This is a schematic diagram of the structure of the trigger, transmission sleeve, guide, and lifting component in the embodiment. Figure 5 This is a schematic diagram of the trigger and guide components in the embodiment. Preferably, the lifting component 2 has a mating part 21 on its surface, the driving component 3 has a spiral groove 31, the mating part 21 slides within the spiral groove 31, and the guide component 4 has a clearance hole 41. The trigger component 1 has a connecting part 112, which is located within the clearance hole 41. The driving component 3 drives the lifting component 2 to rise by rotation. The rising lifting component 2 drives the mating part 21 to rise synchronously. The mating part 21 rises and extends into the clearance hole 41, abutting against the connecting part 112. The rising mating part 21 also drives the connecting part 112 and the trigger component 1 to move to the designated triggering height. In specific applications, the mating part 21 is a transmission pin, and the height of one end of the spiral groove 31 gradually decreases relative to the other end of the spiral groove 31. The drive motor 71 drives the active component 3 to rotate within the housing 5 via the reduction mechanism 72. As the active component 3 rotates, the transmission pin moves from one end of the spiral groove 31 to the other. Due to the obstruction of the clearance hole 41, the transmission pin cannot rotate relative to the central axis of the lifting component 2; that is, the transmission pin only descends vertically along the clearance hole 41. Similarly, as the transmission pin moves from one end of the spiral groove 31 to the other, the lifting component 2 also does not rotate, but only descends vertically. In other words, when the active component 3 rotates, the lifting component 2 descends relative to the active component 3. Likewise, when the drive motor 71 drives in the opposite direction, the lifting component 2 rises relative to the active component 3. Specifically, the lifting component 2 is a lifting sleeve, and its bottom has a connecting hole for installing cleaning components. The active component 3 is a transmission sleeve.

[0026] Rereference Figure 4 and Figure 5Preferably, the guide member 4 is provided with a guide groove 42 along the upward path direction of the mating part 21. The guide groove 42 communicates with the clearance hole 41, and the end of the mating part 21 away from the lifting member 2 slides in the guide groove 42 or the clearance hole 41. The guide groove 42 guides the lifting of the lifting member 2, ensuring that the lifting member 2 only moves vertically relative to the transmission sleeve. It is understood that the end of the mating part 21 away from the lifting member 2 always slides within the guide groove 42 or the clearance hole 41. Specifically, the guide member 4 is a guide sleeve, the housing member 5 includes an outer shell 51 and a locking sleeve 52. The outer shell 51 is fitted over the locking sleeve 52, the locking sleeve 52 is fitted over the guide member 4, the guide member 4 is fitted over the transmission sleeve, and the detection member 6 is located on the outer shell 51. In practical applications, when the drive motor 71 drives the transmission sleeve to rotate within the outer casing 51 via the reduction mechanism 72, the lifting member 2 can descend relative to the transmission sleeve. The guide member 4 remains stationary or nearly stationary under the action of the locking sleeve 52. When the lifting member 2 descends to its limit position, that is, when the transmission pin moves to the other end of the spiral groove 31, as the transmission sleeve continues to rotate, it drives the lifting member 2 to rotate synchronously. The rotation of the lifting member 2, through the force exerted by the transmission pin on the guide groove 42, drives the guide member 4 to rotate synchronously. At this time, the guide member 4 overcomes the resistance of the locking sleeve 52, causing the transmission sleeve, the lifting member 2, and the guide sleeve 52 to rotate synchronously. In other words, when the lifting member 2 descends to its limit position, the continued rotation of the transmission sleeve drives the lifting member 2 to continue rotating synchronously. This continued rotation of the lifting member 2 drives the cleaning component to rotate synchronously to perform cleaning operations on the ground. Specifically, in this embodiment, the locking sleeve 52 is a damping sleeve. Of course, in other embodiments, other locking structures that can achieve the same effect can be used, which will not be elaborated here.

[0027] Rereference Figure 4 and Figure 5 Preferably, there are multiple mating parts 21, spiral grooves 31, clearance holes 41, and guide grooves 42. One end of each mating part 21 is connected to the outer surface of the lifting member 2, and the other end of each mating part 21 passes through the spiral grooves 31 and extends into the clearance holes 41 or guide grooves 42. Each clearance hole 41 is connected to a guide groove 42. In specific applications, in this embodiment, there are three mating parts 21, spiral grooves 31, clearance holes 41, and guide grooves 42. This effectively prevents the lifting member 2 from deviating during its lifting movement relative to the transmission sleeve, ensuring that the lifting member 2 moves vertically and improving its stability. Of course, in other embodiments, the number of mating parts 21, spiral grooves 31, clearance holes 41, and guide grooves 42 may be two, three, or more, which will not be elaborated here.

[0028] Rereference Figure 5Preferably, the trigger 1 includes a trigger part 11 and an elastic part 12. The trigger part 11 is located outside the guide 4 and is either away from or in contact with the lifting member 2. The elastic part 12 is located on the upper surface of the trigger part 11. In specific applications, the elastic part 12 in this embodiment is a compression spring. It can be understood that as the lifting member 2 rises and falls relative to the transmission sleeve, the other end of the mating part 21 also rises and falls relative to the clearance hole 41 or guide groove 42 within the clearance hole 41 or guide groove 42. When the lifting member 2 rises, the mating part 21 also rises synchronously, and the other end of the mating part 21 rises and gradually approaches until it abuts against the detection ring 321. As the lifting member 2 and the mating part 21 continue to rise, the other end of the mating part 21 pushes the trigger part 11 to overcome the elastic resistance of the elastic part 12 and rise until the trigger part 11 rises to the trigger height, that is, when it enters the detection area of ​​the photoelectric sensor, the photoelectric sensor is triggered. At this time, the photoelectric sensor senses that the lifting member 2 has been raised to the correct position, and controls the drive motor 71 to stop driving. Specifically, the triggering part 11 includes a trigger ring 111 and a connecting part 112 disposed on the trigger ring 111. The elastic part 12 is disposed on the upper surface of the trigger ring 111. The trigger ring 111 is sleeved on the outside of the guide member 4. The connecting part 112 extends into the clearance hole 41 and is either away from or abuts against the lifting member 2. In this embodiment, the connecting part 112 is a protrusion located above the other end of the mating part 21. The other end of the mating part 21 pushes the trigger ring 111 upward by acting on the protrusion, overcoming the elastic resistance of the elastic part 12. It should be noted that in other embodiments, the elastic part 12 can also be a tension spring, and the two ends of the elastic part 12 are respectively connected to the outer shell 51 and the lower surface of the trigger ring 111. In this way, the elastic part 12 provides a downward pulling force to the trigger ring 111 at all times, so that the trigger ring 111 is in contact with the upper surface of the other end of the mating part 21. When the lifting member 2 and the mating part 21 rise, the elastic resistance of the elastic part 12 needs to be overcome to push the trigger ring 111 upward. In another embodiment, the elastic part may be omitted, so that the trigger ring 111 falls down by gravity and fits against the upper surface of the other end of the mating part 21. This will not be described in detail here.

[0029] Example 2: The difference between the lifting assembly in this embodiment and that in Embodiment 1 is that the guide groove 42 is provided on the lifting member 2 in this embodiment, and the guide member 4 is provided with a guide part corresponding to the position of the guide groove 42. In this embodiment, the guide part is a guide protrusion. Through the cooperation of the guide part and the guide groove 42, the lifting of the lifting member 2 is guided, thereby improving the stability of the lifting. It can be understood that the function of the mating part 21 in Embodiment 1 is equivalent to the guide part in this embodiment.

[0030] Example 3: The difference between the lifting assembly in this embodiment and that in Embodiment 1 is that the bolt groove 331 in this embodiment is located on the lifting component 2, while the transmission sleeve has a mating part 21 corresponding to the position of the bolt groove 331. It can be understood that in Embodiment 1, the bolt groove 331 is located on the transmission sleeve, while the mating part 21 is located on the lifting component 2. In this embodiment, the bolt groove 331 is located on the lifting component 2, while the transmission sleeve has a mating part 21 corresponding to the position of the bolt groove 331. These two different structures are designed to adapt to different application scenarios.

[0031] Example 4: The cleaning equipment in this embodiment includes a body, a walking mechanism, and a cleaning module as described in Embodiment 1. The walking mechanism and the cleaning module are respectively located on the body. The walking mechanism is used to drive the cleaning equipment to move, while the cleaning module is used to clean the area on the ground that is waiting to be cleaned.

[0032] In summary, the drive motor 71 drives the transmission sleeve to rotate after being reduced in speed by the reduction mechanism 72. The rotation of the transmission sleeve causes the lifting component 2 to descend relative to the transmission sleeve. The descent of the lifting component 2 causes the cleaning assembly to descend and come into close contact with the ground for cleaning operations. When an obstacle is encountered, the drive motor 71 drives the transmission sleeve to rotate in the opposite direction. This reverse rotation causes the lifting component 2 to rise relative to the transmission sleeve. The rise of the lifting component 2 causes the cleaning assembly to rise and move away from the ground, thus avoiding collisions between the cleaning assembly and the obstacle and achieving obstacle avoidance. During the rising process of the lifting component 2, the rising of the lifting component 2 pushes the trigger component 1 to rise to the designated trigger height, detecting… When the measuring element 6 detects that the trigger element 1 has risen to the designated trigger height, it can control the drive motor 71 to stop driving the transmission sleeve to rotate in the reverse direction. The lifting element 2 and the cleaning component will stop rising. It can be understood that when the trigger element 1 rises to the designated trigger height, it means that the lifting height of the cleaning component has been reached. That is, through the setting of the measuring element 6 and the trigger element 1, the detection of the lifting height of the cleaning component is realized, ensuring that the drive motor 71 is stopped only when the lifting height of the cleaning component is reached. This avoids the cleaning component from colliding or scratching with obstacles. Moreover, the timely stopping of the drive motor 71 when the lifting height of the cleaning component is reached reduces energy consumption.

[0033] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
