Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a cleaning device. Background Technology

[0002] As a cleaning device that integrates sweeping and vacuuming, robotic vacuum cleaners have become an important cleaning tool in people's daily lives. In order for robotic vacuum cleaners to be able to overcome obstacles such as thresholds, carpet edges, and power cords while cleaning the surface to be cleaned, the chassis is usually raised to make the gap between the chassis and the surface to be cleaned large enough so that it can overcome obstacles.

[0003] In the process of developing this application, the inventors discovered that currently, there are two technical solutions for sweeping robots to overcome obstacles: one is a passive lifting method, such as a suspended adaptive structure, which passively lifts the chassis through springs or elastic elements, but its lifting height is limited and cannot handle steep slopes or soft obstacles (such as carpets); the other is an active lifting method, such as a motor or hydraulic device actively lifting the chassis, or a wheel linkage mechanism linking to lift the chassis. However, the structure of a motor or hydraulic device actively lifting the chassis is complex and the design and production costs are high. The mechanical structure of the wheel linkage mechanism linking to lift the chassis is prone to wear, and its reliability gradually decreases with use. The aforementioned passive lifting mechanism cannot meet the needs of existing cleaning robots, and the active mechanism has a complex structure, which affects the application of chassis lifting function in cleaning robots. Utility Model Content

[0004] This application provides a cleaning device, which mainly solves the technical problem that the active lifting structure of existing cleaning devices is complicated, and the passive lifting structure cannot cope with complex working environments, affecting the application of chassis lifting function in cleaning robots.

[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution: A cleaning device is provided, comprising: a main body, a roller assembly, a drive assembly, and a rotating assembly. The main body is provided with a receiving groove, the roller assembly is received in the receiving groove, a portion of the roller assembly extends out of the receiving groove and abuts against the surface to be cleaned, and one end of the roller assembly is rotatably connected to the main body. The drive assembly is disposed on the main body, and its output end is connected to the roller assembly. The drive assembly is used to drive the rollers of the roller assembly to rotate. The rotating assembly is disposed on the main body, and its other end is rolledly connected to the roller assembly. The rotating assembly is used to drive the roller assembly to move relative to the main body between a preset first position and a preset second position. When the roller assembly is in the preset first position, the main body is parallel to the surface to be cleaned. When the roller assembly is in the preset second position, the main body forms an angle with the surface to be cleaned, such that a portion of the main body is raised and / or lowered relative to the surface to be cleaned.

[0006] Optionally, the roller assembly is provided with a driven tooth, and the rotating assembly includes a driving member and a driving gear. The output end of the driving member is connected to the driving gear, and the driving gear meshes with the driven tooth. The driving gear is used to drive the driven tooth to rotate when the driving member drives the driving gear to rotate.

[0007] Optionally, the main body is provided with a rotating groove, the roller assembly includes a rotating shell, a roller and a rotating shaft, the driven tooth is provided in the rotating shell, the roller is rotatably provided in the rotating shell, a portion of the roller extends out of the rotating shell and abuts against the surface to be cleaned, one end of the rotating shaft is fixed to the end of the rotating shell away from the roller, and the other end of the rotating shaft is rotatably accommodated in the rotating groove.

[0008] Optionally, the rotating housing is provided with a receiving groove, and at least a portion of the drive assembly is received in the receiving groove.

[0009] Optionally, the cleaning device includes a detection component disposed on the main body, the detection component being used to release a detection signal to determine the position of the roller assembly.

[0010] Optionally, the detection component includes a first grating and a second grating, the first grating and the second grating being spaced apart, and the distance between the first grating and the second grating being equal to the distance the roller assembly moves from a preset first position to a preset second position.

[0011] Optionally, the roller assembly includes a reduction gearbox, one end of which is connected to the drive assembly, and the other end of which is connected to the roller of the roller assembly. The reduction gearbox is used to reduce the rotational speed output by the drive assembly.

[0012] Optionally, the roller assembly further includes a limiting member, which is fixed to the housing of the gearbox. When the roller assembly moves to a preset first position, the limiting member abuts against the inner wall of the receiving groove.

[0013] Optionally, there are two of each of the roller assembly, the drive assembly, and the rotating assembly. One drive assembly, one roller assembly, and one rotating assembly are all housed on one side of the receiving groove, while the other drive assembly, the other roller assembly, and the other rotating assembly are all housed on the other side of the receiving groove.

[0014] Optionally, the cleaning device includes a caster wheel assembly, which is rotatably mounted on the main body. The caster wheel assembly and the roller assembly are spaced apart and located on the same side of the main body.

[0015] The beneficial effects of this application embodiment are as follows: Unlike existing technologies, this application embodiment provides a cleaning device including a main body, a roller assembly, a drive assembly, and a rotating assembly. The main body is provided with a receiving groove, and the roller assembly is rotatably disposed in the receiving groove, with a portion of the roller assembly extending out of the rotating groove and abutting against a surface to be cleaned.

When the roller assembly is in the preset first position, the main body is parallel to the surface to be cleaned. When the roller assembly is in the preset second position, the main body forms an angle with the surface to be cleaned, causing a portion of the main body to rise relative to the surface to be cleaned. Through the above structure, this application embodiment can drive the roller assembly to rotate between the preset first position and the preset second position via the rotating assembly, allowing the chassis of the cleaning device to move away from the surface to be cleaned when in the preset second position, thereby achieving the function of crossing obstacles.

[0033] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0034] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0035] To achieve obstacle avoidance, existing cleaning equipment commonly employs passive or active lifting methods. Passive lifting uses elastic components, but its lifting height is limited, making it unsuitable for steep slopes and soft obstacles (such as carpets). Active lifting uses hydraulic mechanisms or motor-wheel linkages, but these are structurally complex. The aforementioned methods using hydraulic structures or motor-wheel linkages are particularly complex and costly, limiting the application of lifting functionality in cleaning equipment.

[0036] To resolve the above issues, please refer to [link / reference]. Figures 1 to 4 This application provides a cleaning device 100, including: a main body 1, a roller assembly 2, a drive assembly 3, and a rotating assembly 4. The main body 1 is provided with a receiving groove 11 for accommodating and supporting various control components and motion components (roller assembly, rotating assembly, etc.). The roller assembly 2 is received in the receiving groove 11, with a portion extending out of the receiving groove 11 and abutting against a surface S to be cleaned, thus creating a gap between the main body 1 and the surface S to be cleaned. One end of the roller assembly 2 is rotatably connected to the main body 1, allowing the roller assembly 2 to rotate around the connection point between one end of the roller assembly 2 and the main body 1. The drive assembly 3 is disposed on the main body 1. The output end of component 3 is connected to roller assembly 2. Specifically, the output end of drive component 3 is connected to roller 23 of roller assembly 2. Drive component 3 is used to drive roller 23 of roller assembly 2 to rotate. By relying on the relative rolling of roller 23 and the surface to be cleaned S, the cleaning device 100 can move relative to the surface to be cleaned S. Rotation component 4 is disposed on the main body 1. Rotation component 4 is rolledly connected to the other end of roller assembly 2. Rotation component 4 is used to drive roller assembly 2 to rotate around the connection position between one end of roller assembly 2 and the main body 1, so that roller assembly 2 moves relative to the main body 1 between a preset first position L1 and a preset second position L2.

[0037] For details, please refer to 3 and Figure 4Driven by the rotating component 4, when the roller assembly 2 is in the preset first position L1, the main body 1 is parallel to the surface S to be cleaned, so that the cleaning mechanism set on the main body 1 can clean the surface S. When the roller assembly 2 is in the preset second position L2, the main body 1 is at an angle to the surface S to be cleaned, so that a part of the main body 1 is raised relative to the surface S to be cleaned, thereby facilitating the cleaning device 100 to cross obstacles. And / or when the roller assembly 2 is in the preset second position L2, the main body 1 is at an angle to the surface S to be cleaned, so that a part of the main body 1 is lowered relative to the surface S to be cleaned, thereby reducing the distance between the part of the main body 1 and the surface S to be cleaned, thereby improving the cleaning ability of the cleaning device 100 for the surface S to be cleaned.

[0038] Understandably, when the roller assembly 2 is in the preset second position L2, the angle between the main body 1 and the surface S to be cleaned is selected according to the actual design requirements, as long as the angle between the main body 1 and the surface S to be cleaned is sufficient to achieve the local lifting and / or sinking of the main body 1 relative to the surface S to be cleaned.

[0039] It should be noted that the distance between the preset first position L1 and the preset second position L2 is the maximum stroke that the roller assembly 2 can move under the drive of the rotating assembly 4. Depending on the different heights of obstacles faced by the cleaning device 100, the cleaning device 100 can also make the roller assembly 2 hover at any position between the preset first position L1 and the preset second position L2 under the drive of the rotating assembly 4, so that the cleaning device 100 can achieve the adjustable angle between the main body 1 and the surface S to be cleaned, thereby making the height of the part of the main body 1 raised and / or lowered relative to the surface S to be cleaned adjustable.

[0040] It is understood that the cleaning device 100 may employ a structure that includes, but is not limited to, one or more combinations of sweeping components, vacuuming components, and mopping components to achieve cleaning. To facilitate understanding of this application, an example is provided: when the cleaning device 100 uses a vacuuming component as the cleaning mechanism, based on the cooperation of the aforementioned rotating component 4 and roller component 2, when the cleaning device 100 faces an obstacle, it can select an appropriate lifting height according to the obstacle. Furthermore, when the cleaning device 100 faces complex uneven surfaces or surfaces S with a lot of dirt, it can adjust the gap between the bottom of the cleaning device 100 and the surface S by selecting different lowering heights to adjust the suction power of the vacuuming component.

[0041] It should be noted that when a part of the main body 1 can be raised and lowered relative to the surface S to be cleaned, there are two preset second positions L2. One of them is the position of the roller assembly 2 when the main body 1 can be raised to the highest height relative to the surface S to be cleaned, and the other is the position of the roller assembly 2 when the main body 1 can be lowered to the lowest height relative to the surface S to be cleaned. When a part of the main body 1 can be raised or lowered relative to the surface S to be cleaned, there is one preset second position L2, which is selected according to the raising or lowering of the main body 1.

[0042] It is understandable that the structure in which the rotating component 4 and the roller component 2 are connected in a rolling manner includes, but is not limited to, the following: worm gear and worm shaft meshing, gear and tooth meshing, etc.

[0043] For example, in this embodiment, the structure in which the rotating component 4 drives the roller component 2 to rotate relative to the main body 1 is a gear and tooth meshing structure. For details, please refer to [link to relevant documentation]. Figure 5 and Figure 6 The roller assembly 2 is provided with a driven tooth 21, which is arc-shaped so that it can adapt to the rotation of the roller assembly 2. The rotating assembly 4 includes a driving member (not shown) and a driving gear 41. The output end of the driving member is connected to the driving gear 41. The driving gear 41 meshes with the driven tooth 21. The driving gear 41 is used to drive the driven tooth 21 to rotate when the driving member drives the driving gear 41 to rotate.

[0044] Understandably, the roller assembly 2 is controlled to be in different positions depending on the meshing position of the drive gear 41 and the driven gear 21. Moreover, the reciprocating rotation of the rotating assembly 4 between the preset first position L1 and the preset second position L2 can be achieved by controlling the forward and reverse rotation of the drive gear 41, that is, by controlling the forward and reverse rotation of the motor connected to the drive gear 41.

[0045] It should be noted that the arc length of the arc-shaped driven tooth 21 is greater than the arc length path through which the driven gear 41 drives the driven tooth 21 to rotate, so as to ensure that the driven tooth 21 has sufficient length when the drive assembly 3 drives the roller assembly 2 to rise and / or sink, so as to avoid the disengagement of the driven tooth 21 and the drive gear 41.

[0046] Furthermore, in some embodiments, the main body 1 is provided with a rotating groove 12, and the roller assembly 2 includes a rotating shell 22, a roller 23 and a rotating shaft 24. The driven tooth 21 is provided in the rotating shell 22, and the roller 23 is rotatably provided in the rotating shell 22. A portion of the roller 23 extends out of the rotating shell 22 and abuts against the receiving cleaning plane S. The rotating shell 22 covers a portion of the roller 23, thereby forming a protection for the roller 23. The presence of the rotating shell 22 effectively prevents dust, mud and other dirt picked up by the roller 23 during the rolling process from being rolled into the receiving groove 11. One end of the rotating shaft 24 is fixed to the end of the rotating shell 22 away from the roller 23, and the other end of the rotating shaft 24 is rotatably accommodated in the rotating groove 12.

[0047] Understandably, the inner wall of the rotating groove 12 is lubricated to the rotating shaft 24 to facilitate the rotation of the rotating shaft 24, for example, by applying lubricating oil; or a bearing is installed in the rotating groove 12, with the inner wall of the bearing fitted onto the other end of the rotating shaft 24 and the outer wall of the bearing abutting against the inner wall of the rotating groove 12, so that the sliding friction between the rotating shaft 24 and the inner wall of the rotating groove 12 is converted into rolling friction between the bearing balls and the bearing ring by the bearing.

[0048] In some embodiments, the rotating shaft 24 and the rotating housing 22 are integrally formed to simplify the assembly steps of the roller assembly 2, thereby improving the assembly efficiency of the cleaning equipment 100 and facilitating the mass production of the cleaning equipment 100.

[0049] Furthermore, the rotating housing 22 is provided with a receiving groove 221, and at least a portion of the drive component 3 is received in the receiving groove 221, so that the drive component 3 can move with the rotation of the rotating housing 22. Compared with the setting method in which the drive component 3 is fixed in the receiving groove 11 and drives the roller 23 to rotate through a complex linkage transmission structure, the structure of this application, in which the drive component 3 rotates with the rotating housing 22, ensures that the rotation of the roller 23 is not affected by the rotation of the roller component 2 between the preset first position L1 and the preset second position L2, and also improves the integration of the cleaning equipment 100, which is conducive to the miniaturization of the cleaning equipment 100.

[0050] Understandably, the rotational speed output by the output end of the drive component 3 is too fast. In order to make the rotational speed output by the output end of the drive component 3 suitable for the movement of the cleaning equipment 100, a certain deceleration mechanism needs to be set to reduce the rotational speed of the output end. Therefore, in some embodiments, the roller assembly 2 includes a deceleration box 25. One end of the deceleration box 25 is connected to the drive component 3, and the other end of the deceleration box 25 is connected to the roller 23 of the roller assembly 2. The deceleration box 25 is used to reduce the rotational speed output by the drive component 3.

[0051] In order to improve the integration of the roller assembly 2, in some embodiments, the housing of the gearbox 25 and the rotating housing 22 are integrally formed, which facilitates the assembly of the roller assembly 2 and is conducive to the mass production of the roller assembly 2.

[0052] Furthermore, the roller assembly 2 also includes a limiting member 26, which is used to limit the rotation of the roller assembly 2, to prevent the roller assembly 2 from rotating excessively during the process of rotating to the preset first position L1, thereby causing the roller assembly 2 to collide with the inner wall of the receiving groove 11; and / or to prevent the roller assembly 2 from rotating too much during the process of rotating to the preset second position L2, causing the meshing between the driving gear 41 and the driven gear 21 to disengage.

[0053] Specifically, in some embodiments, the limiting member 26 is fixed to the housing of the gearbox 25, and when the roller assembly 2 moves to the preset first position L1, the limiting member 26 abuts against the inner wall of the receiving groove 11.

[0054] It should be noted that, since the roller assembly 2 of the cleaning equipment 100 spends a larger proportion of time in the preset first position L1 than in the preset second position L2 during actual operation, in this application, the limiting member 26 preferably abuts against the inner wall of the receiving groove 11 when the roller assembly 2 moves to the preset first position L1. The limiting member 26 provides a force-bearing support for the roller assembly 2 as a whole, improving the stability of the roller assembly 2 in maintaining the preset first position L1 for a long time. In other embodiments, when the roller assembly 2 moves to the preset first position L1, a certain first gap can be reserved between the limiting member 26 and the inner wall of the receiving groove 11 as a buffer protection measure for the roller assembly 2 to rotate to the preset first position L1 and the rotation angle is too large. That is, when the roller assembly 2 fails to stop successfully at the preset first position L1, the limiting member 26 abuts against the inner wall of the receiving groove 11 after the roller assembly 2 continues to rotate a distance of the first gap.

[0055] In some other embodiments, the limiting member 26 may also be disposed on the inner wall of the receiving groove 11, and when the roller assembly 2 moves to the preset first position L1, the limiting member 26 abuts against the inner wall of the receiving groove 11.

[0056] It should be noted that, in order to prevent the roller assembly 2 from rotating too much when it moves to the preset second position L2 and failing to stop rotating at the preset second position L2, an abutment can be provided similarly to the limiting member 26 provided above for the roller assembly 2 to move to the preset first position L1. For example, an abutment can be provided on the inner wall of the receiving groove 11, and an abutment part can be provided on the housing of the reducer. When the roller assembly 2 is in the preset second position L2, the abutment abuts against the abutment part. Specific structures will not be described in detail here.

[0057] In some embodiments, please refer to Figure 5 The cleaning equipment 100 includes a detection component 5, which is disposed on the main body 1. The detection component 5 is used to release a detection signal to determine the position of the roller assembly 2. After receiving the detection signal after feedback from the outside, the detection component 5 determines the position of the detection component 5, thereby facilitating the control component of the cleaning equipment 100 to control the rotation of the roller assembly 2.

[0058] Specifically, the detection component 5 includes a first grating 51 and a second grating 52. The first grating 51 and the second grating 52 are spaced apart and are adjacent to the driven gear 21. The first grating 51 and the second grating 52 are located on both sides of the drive gear 41. The first grating 51 is closer to the bottom wall of the receiving groove 11 than the second grating 52. The arc line connecting the first grating 51, the drive gear 41 and the second grating 52 is parallel to the arc line of the roller assembly 2 rotating between the preset first position L1 and the preset second position L2, so as to ensure the normal operation of the detection function of the detection component 5 for detecting the position of the roller assembly 2. The distance between the first grating 51 and the second grating 52 is equal to the distance the roller assembly 2 moves from the preset first position L1 to the preset second position L2.

[0059] To facilitate understanding of the working principle of the detection component 5, an example is given here. The first grating 51 detects the signal fed back by the driven tooth 21, and the second grating 52 detects the signal fed back by the driven tooth 21. At this time, it is determined that the cleaning device 100 is in the preset first position L1. As the drive component 3 drives the roller component 2 to rotate, the first grating 51 detects the signal fed back by the driven tooth 21, and the second grating 52 does not detect the signal fed back by the driven tooth 21. At this time, it is determined that the main body 1 of the cleaning device 100 is in the preset second position L2, which is downward toward the surface S to be cleaned. The first grating 51 does not detect the signal fed back by the driven tooth 21, and the second grating 52 detects the signal fed back by the driven tooth 21. Then it is determined that the main body 1 of the cleaning device 100 is in the preset second position L2, which is raised away from the surface S to be cleaned.

[0060] Understandably, since the length of the driven tooth 21 needs to ensure that the roller assembly 2 will not disengage from the drive gear 41 during the lifting or lowering process, there may be inaccurate judgment of the detection logic during the movement of the roller assembly 2 from the preset first position L1 to the preset second position L2. Therefore, when the roller assembly 2 is at the preset first position L1, a marker sensing point can be set on the driven tooth 21 to assist the detection component in accurately determining whether the roller assembly 2 is at the preset first position L1 or in the process of moving from the preset first position L1 to the preset second position L2.

[0061] Furthermore, in order to enable the roller assembly 2 to hover at any position between the preset first position L1 and the preset second position L2, it is also necessary to control the number of rotations and the direction of rotation of the driving component. The specific control logic and its coordination with the above-mentioned judgment logic will not be illustrated here.

[0062] It should be noted that in this application, the number of roller assembly 2, drive assembly 3 and rotating assembly 4 are all two. One drive assembly 3, one roller assembly 2 and one rotating assembly 4 are all housed on one side of the receiving groove 11, and the other drive assembly 3, another roller assembly 2 and another rotating assembly 4 are all housed on the other side of the receiving groove 11. This constitutes a symmetrical structure of the cleaning device 100, which makes the cleaning device 100 symmetrically move and symmetrically lift on both sides. Through this structure, the stability of the cleaning device 100 when moving, lifting and sinking is improved.

[0063] In some embodiments, the cleaning device 100 includes a caster wheel assembly 6, which is rotatably mounted on the main body 1. The caster wheel assembly 6 and the roller assembly 2 are spaced apart and located on the same side of the main body 1. The caster wheel assembly 6, together with the two roller assemblies 2, forms a triangular rolling movement mechanism, improving the stability of the cleaning device 100 during movement. Furthermore, the caster wheel assembly 6 facilitates the turning operation of the cleaning device 100 and reduces friction during rotation.

[0064] Understandably, the direction of the cleaning device 100 can be achieved by controlling the speed difference between the two roller assemblies 2. For ease of description, one roller assembly 2 is defined as the left roller assembly 2 and the other roller assembly 2 is defined as the right roller assembly 2. By controlling the acceleration of the left roller assembly 2 or the deceleration of the right roller assembly 2, the cleaning device 100 can be turned to the right. By controlling the deceleration of the left roller assembly 2 or the acceleration of the right roller assembly 2, the cleaning device 100 can be turned to the left.

[0065] To achieve the control of the above-mentioned multiple functions, the cleaning equipment 100 includes a control component (not shown). The control component is electrically connected to the drive component 3, the rotation component 4, and the cleaning mechanism. The control component carries algorithms and programs for driving the drive component 3, the rotation component 4, and the cleaning mechanism. The control component is used to control the time for the drive component 3 to drive the roller 23 of the roller assembly 2 to rotate, the start and stop of the rotation of the roller 23, etc.; to control the start and stop of the rotation of the rotation component 4, the duration of rotation, the direction of rotation, etc.; and to control the working duration and the switching of the working state of the cleaning mechanism, etc.

[0066] In this application, the cleaning device 100 includes a main body 1, a roller assembly 2, a drive assembly 3, and a rotating assembly 4. The main body 1 is provided with a receiving groove 11. The roller assembly 2 is received in the receiving groove 11, and a portion of the roller assembly 2 extends out of the rotating groove 12 and abuts against the cleaning surface S. One end of the roller assembly 2 is rotatably connected to the main body 1. The drive assembly 3 is disposed on the main body 1, and the output end of the drive assembly 3 is connected to the roller assembly 2. The drive assembly 3 is used to drive the roller 23 of the roller assembly 2 to rotate. The rotating assembly 4 is disposed on the main body 1 and is tactilely connected to the other end of the roller assembly 2. The rotating assembly 4 is used to drive the roller assembly 2 to rotate relative to the main body 1 between a preset first position L1 and a preset second position L2. When the roller assembly 2 is in the preset first position L1, the main body 1 is parallel to the cleaning surface S. When the roller assembly 2 is in the preset second position L2, the main body 1 forms an angle with the cleaning surface S, so that a portion of the main body 1 is raised and / or lowered relative to the cleaning surface S. With the above structure, the roller assembly 2 is driven by the rotating component 4 to reciprocate between the preset first position L1 and the preset second position L2, thereby realizing the lifting and / or lowering of the roller assembly 2 relative to the surface to be cleaned S. This allows the cleaning equipment 100 to smoothly overcome obstacles and improve its cleaning ability to handle complex surfaces to be cleaned S. Compared with the existing active linkage hydraulic lifting mechanism, the structure of the lifting function in this application is simple and conducive to the application of the lifting function in the cleaning equipment 100.
