[0008] A connecting rod shaft, with both ends of the connecting rod shaft connected to a fixing member and a rotating disk respectively, and a center line of the connecting shaft does not coincide with a center line of the connecting rod shaft;

[0009] When the floating member is connected to the rotating disk and the floating member rotates, the rotating disk rotates relative to the fixed member with the connecting rod shaft as the axis, so that the movable member rotates relative to the fixed member.

[0024] Typical embodiments that embody the features and advantages of the present disclosure will be described in detail in the following description. It should be understood that the present disclosure can have various changes in different embodiments without departing from the scope of the present disclosure, and the descriptions and drawings therein are essentially for illustrative purposes rather than for limiting the present disclosure.

[0025] In the following description of different exemplary embodiments of the present disclosure, reference is made to the accompanying drawings, which form a part of the present disclosure and in which different exemplary structures, systems and steps that can implement multiple aspects of the present disclosure are shown by way of example. It should be understood that other specific schemes of components, structures, exemplary devices, systems and steps can be used, and structural and functional modifications can be made without departing from the scope of the present disclosure. Moreover, although the terms "above", "between", "within", etc. may be used in this specification to describe different exemplary features and elements of the present disclosure, these terms are used herein only for convenience, such as according to the direction of the examples in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of the present disclosure.

[0026] An embodiment of the present disclosure provides a position adjustment mechanism, please refer to Figures 1 to 7 The position adjustment mechanism is used to connect the movable part 1 and the fixed part 2, the movable part 1 is used to accommodate the first peripheral component 3 and / or the second peripheral component 4, and the fixed part 2 is used to be fixedly connected to the device body, so that the position of the first peripheral component and / or the second peripheral component can be changed by the movement of the movable part 1 relative to the fixed part 2, thereby realizing multiple working modes.

[0027] The position adjustment mechanism includes: a connecting shaft 10; a turntable 20, wherein the two ends of the connecting shaft 10 are respectively connected to the movable part 1 and the turntable 20; a floating part 30, wherein the floating part 30 is movably arranged on the connecting shaft 10 to be connected to or separated from the turntable 20; a connecting rod shaft 40, wherein the two ends of the connecting rod shaft 40 are respectively connected to the fixed part 2 and the turntable 20, and the center line of the connecting shaft 10 does not coincide with the center line of the connecting rod shaft 40; wherein, when the floating part 30 is connected to the turntable 20 and the floating part 30 rotates, the turntable 20 rotates relative to the fixed part 2 with the connecting rod shaft 40 as the axis, so that the movable part 1 rotates relative to the fixed part 2.

[0028] The position adjustment mechanism of an embodiment of the present disclosure can enable the movable part 1 to rotate relative to the fixed part 2 through the connecting shaft 10, the turntable 20, the floating part 30 and the connecting rod shaft 40, and before the movable part 1 rotates relative to the fixed part 2, it is necessary to ensure that the floating part 30 is connected to the turntable 20, that is, it is necessary to move the floating part 30 along the connecting shaft 10 to connect with the turntable 20, so as to form a certain rotation start buffer.

[0029] It should be noted that since the floating member 30 and the turntable 20 have two states, connected and separated, when the floating member 30 and the turntable 20 are in the separated state, if it is necessary to drive the movable member 1 to rotate relative to the fixed member 2 through the floating member 30, it is necessary to ensure that the floating member 30 and the turntable 20 move from the separated state to the connected state. At this time, the floating member 30 rotates, thereby driving the turntable 20 to rotate relative to the fixed member 2 with the connecting rod shaft 40 as the axis, and the floating member 30 and the turntable 20 are both connected to the connecting shaft 10, and the connecting shaft 10 is connected to the movable member 1, so the connecting shaft 10 can drive the movable member 1 to rotate.

[0030] Considering that when the floating member 30 rotates relative to the connecting shaft 10, the floating member 30 will drive the turntable 20 to rotate, and the turntable 20 is connected to the fixed member 2 through the connecting rod shaft 40, and the center line of the connecting shaft 10 does not coincide with the center line of the connecting rod shaft 40, therefore, under the driving force of the floating member 30, the turntable 20 will rotate relative to the connecting shaft 10 while also rotating relative to the fixed member 2 with the connecting rod shaft 40 as the axis, that is, the turntable 20 and the floating member 30 complete rotation and revolution at the same time, thereby realizing the rotation of the movable member 1 relative to the fixed member 2.

[0031] It should be noted that the floating member 30 can rotate relative to the connecting shaft 10 . Of course, the floating member 30 can also be circumferentially fixed to the connecting shaft 10 , that is, the floating member 30 can drive the connecting shaft 10 to rotate relative to the movable member 1 .

[0032] In one embodiment, the floating member 30 can be driven by an external driving mechanism to achieve movement relative to the connecting shaft 10. For example, the external driving mechanism can include a telescopic rod connected to the floating member 30. The extension and retraction of the telescopic rod can achieve movement of the floating member 30 along the connecting shaft 10. When the floating member 30 rotates, the external driving mechanism can rotate synchronously with the floating member 30.

[0033] For the rotation of the floating member 30, a transmission mechanism in the relevant technology can be used to ensure that the floating member 30 can rotate. For example, a gear transmission mechanism, a chain transmission mechanism or a belt transmission mechanism can be used. There is no limitation here. It is sufficient as long as the transmission mechanism can drive the floating member 30 to rotate and can rotate relative to the connecting rod shaft 40 at the same time as the floating member 30.

[0034] In one embodiment, the connecting rod shaft 40 can be directly connected to the rotating disk 20, that is, there is no need for a switching mechanism between the connecting rod shaft 40 and the rotating disk 20, and it is only necessary to ensure that the center line of the connecting shaft 10 and the center line of the connecting rod shaft 40 do not overlap, so that the rotating disk 20 can rotate relative to the fixed part 2 with the connecting rod shaft 40 as the axis. For example, the connecting rod shaft 40 is fixedly connected to the rotating disk 20, that is, the connecting rod shaft 40 is set away from the connecting shaft 10, and the connecting rod shaft 40 is rotatable relative to the fixed part 2, so that when the floating part 30 is connected to the rotating disk 20 and the floating part 30 rotates, the rotating disk 20 will drive the connecting rod shaft 40 to rotate relative to the fixed part 2, and the rotating disk 20 is similar to an eccentric disk. Of course, the connecting rod shaft 40 and the rotating disk 20 can be rotatably connected, and the connecting rod shaft 40 and the fixed part 2 are fixedly connected.

[0035] In one embodiment, Figures 1 to 3 As shown, the position adjustment mechanism also includes: an adapter 50, the two ends of which are respectively connected to the turntable 20 and the connecting rod shaft 40, so that the connecting rod shaft 40 is connected to the turntable 20 through the adapter 50, so that the position relationship between the connecting rod shaft 40 and the turntable 20 will not be subject to special restrictions, thereby ensuring a reasonable layout between the components.

[0036] Specific, combined Figure 1 The adapter 50 may be a connecting plate, and the connection point between the adapter 50 and the turntable 20 is offset from the center line of the turntable 20 , that is, offset from the center line of the connecting shaft 10 .

[0037] In one embodiment, the connecting rod shaft 40 is fixedly connected to the fixing member 2, and the two ends of the adapter 50 are respectively hinged to the turntable 20 and the connecting rod shaft 40, so that when the turntable 20 rotates, the adapter 50 can rotate relative to the turntable 20 and the connecting rod shaft 40 to prevent jamming.

[0038] Specifically, since the floating member 30 and the turntable 20 rotate and revolve simultaneously, it is necessary to ensure that the adapter 50 does not get stuck, so both ends of the adapter 50 need to be hinged ends.

[0039] In one embodiment, Figure 1 As shown, a first protrusion 21 is provided on the side of the turntable 20 facing the floating member 30, and a second protrusion 31 is provided on the side of the floating member 30 facing the turntable 20, so that when the floating member 30 is connected to the turntable 20, the first protrusion 21 and the second protrusion 31 are in limited contact, thereby ensuring that the floating member 30 can drive the turntable 20 to rotate.

[0040] Specifically, there can be multiple first protrusions 21, and multiple first protrusions 21 are arranged at intervals along the circumferential direction of the floating member 30, and there can be multiple second protrusions 31, and multiple second protrusions 31 are arranged at intervals along the circumferential direction of the turntable 20. When the floating member 30 is connected to the turntable 20, the first protrusions 21 and the second protrusions 31 can be staggered to form a relatively fixed relationship. Or one of the first protrusions 21 and the second protrusions 31 is formed with a groove, and the other is inserted into the groove to form a relatively fixed relationship. There is no limitation on the limiting connection relationship between the first protrusion 21 and the second protrusion 31, as long as it can be limited and separated. In this embodiment, multiple first protrusions 21 can form a spiral external gear with the turntable 20, and multiple second protrusions 31 can form a spiral internal gear with the floating member 30, or, multiple first protrusions 21 can form a spiral internal gear with the turntable 20, and multiple second protrusions 31 can form a spiral external gear with the floating member 30, and the spiral external gear is meshed with the spiral internal gear.

[0041] In one embodiment, Figure 1 As shown, the position adjustment mechanism also includes: a first drive component 60, which is connected to the floating member 30 to drive the floating member 30 to rotate and move along the connecting rod shaft 40; wherein the first drive component 60 and the turntable 20 rotate synchronously relative to the fixed member 2, that is, the first drive component 60 can maintain a connection relationship with the floating member 30, thereby ensuring power transmission.

[0042] It should be noted that the floating member 30 can move relative to the connecting shaft 10 while rotating, that is, the first drive assembly 60 needs to provide both axial force and circumferential force to the floating member 30. It is not excluded that the first drive assembly 60 includes two sets of relatively independent drive mechanisms, which respectively provide forces in two directions to the floating member 30.

[0043] In one embodiment, Figure 3As shown, the floating member 30 includes a first bevel gear segment 32, and the first driving assembly 60 includes: a first transmission gear 61, the first transmission gear 61 includes a second bevel gear segment 611, and the second bevel gear segment 611 is meshed with the first bevel gear segment 32 to drive the floating member 30 to rotate; wherein, the floating member 30 is movably arranged along the second bevel gear segment 611, that is, the floating member 30 can be movably arranged relative to the axial direction of the second bevel gear segment 611.

[0044] Specifically, the second bevel gear segment 611 and the first bevel gear segment 32 are bevel gears, so that when the second bevel gear segment 611 rotates, the second bevel gear segment 611 can provide two-directional forces to the first bevel gear segment 32, ensuring that the first bevel gear segment 32 rotates and moves synchronously, thereby connecting the floating member 30 with the turntable 20. After the floating member 30 is connected to the turntable 20, due to the limitation of the turntable 20, the floating member 30 will not continue to move along the connecting shaft 10, but will still rotate under the drive of the second bevel gear segment 611, thereby driving the turntable 20 to rotate.

[0045] In one embodiment, Figure 2 and Figure 3 As shown, the first driving assembly 60 further includes: a second transmission gear 62 , which is meshed with the first transmission gear 61 ; and a first power source 63 , which is connected to the second transmission gear 62 to drive the second transmission gear 62 to rotate.

[0046] Specifically, the first power source 63 may be a motor, which drives the second transmission gear 62 to rotate, thereby driving the first transmission gear 61 to rotate, thereby transmitting power to the floating member 30 through the first transmission gear 61. In this embodiment, the first power source 63 may be a motor, which can realize forward and reverse rotation.

[0047] In one embodiment, the first power source 63 may also be directly connected to the first transmission gear 61 to drive the first transmission gear 61 to rotate. Alternatively, other transmission gears may be provided between the first power source 63 and the second transmission gear 62 to meet the transmission ratio requirement.

[0048] In one embodiment, Figure 2 and Figure 3 As shown, the floating member 30 also includes an output gear segment 33, and the first drive assembly 60 also includes: a first output gear 64, the first output gear 64 is used to connect the first external component 3, the output gear segment 33 is engaged with the first output gear 64 to drive the first output gear 64 to rotate; wherein, the floating member 30 is movably arranged along the first output gear 64, that is, the floating member 30 can be movably arranged relative to the axial direction of the first output gear 64.

[0049] Specifically, the floating member 30 can be used to drive the turntable 20 to rotate, that is, to realize the rotation of the movable member 1 relative to the fixed member 2, and when the floating member 30 rotates, it can also be used to drive the first peripheral component 3 to work, that is, one power member realizes two functions, which can reduce the setting of the power component to a certain extent.

[0050] It should be noted that, after the floating member 30 is connected to the turntable 20, the rotation of the floating member 30 will cause the movable member 1 to rotate relative to the fixed member 2. Therefore, after the floating member 30 is connected to the turntable 20, the rotation of the floating member 30 can also drive the first peripheral component 3 to work. After the floating member 30 is separated from the turntable 20, the rotation of the floating member 30 can also drive the first peripheral component 3 to work, that is, the floating member 30 can rotate in two directions.

[0051] It should be noted that since the floating member 30 can move relative to the connecting shaft 10, the floating member 30 can move relative to the first transmission gear 61 and the first output gear 64 meshing therewith, but the moving distance has a fixed value, thereby ensuring that the floating member 30 is in a state of constant meshing with the first transmission gear 61, and the floating member 30 is also in a state of constant meshing with the first output gear 64.

[0052] In one embodiment, the floating member 30 is rotatable along both the first direction and the second direction; when the floating member 30 rotates along the first direction, the floating member 30 moves to connect with the turntable 20, and causes the movable member 1 to rotate a preset angle relative to the fixed member 2; when the floating member 30 rotates along the second direction, the floating member 30 moves to separate from the turntable 20.

[0053] Specifically, when the floating member 30 rotates in the first direction, the floating member 30 moves in a direction close to the rotating disk 20 and moves to be connected with the rotating disk 20, such as Figure 6 As shown in FIG. 1 , at this time, the floating member 30 continues to rotate in the first direction, thereby driving the rotating disk 20 to rotate, so that the movable member 1 rotates from the first position to the second position relative to the fixed member 2. When the floating member 30 rotates in the second direction, the floating member 30 drives the rotating disk 20 to rotate, and the movable member 1 rotates from the second position to the first position relative to the fixed member 2, and the floating member 30 separates from the rotating disk 20, as shown in FIG. Figure 5 shown.

[0054] In one embodiment, Figures 4 to 6As shown, the position adjustment mechanism also includes: a baffle 70, which is used to be set on the fixed part 2, and a notch 71 is set on the baffle 70; wherein, when the floating part 30 rotates along the first direction and makes the movable part 1 rotate relative to the fixed part 2 by a preset angle, the connecting shaft 10 is clamped in the notch 71; when the floating part 30 rotates along the second direction and makes the connecting shaft 10 disengage from the notch 71, the floating part 30 moves along the connecting shaft 10 to be separated from the turntable 20. In certain extreme cases, the floating part 30 moves to be separated from the turntable 20 and contacts with the baffle 70 in a limiting manner.

[0055] Specifically, when the floating member 30 drives the rotating disk 20 to rotate, the connecting shaft 10 rotates with it, and thus the end of the notch 71 enters the notch 71 until it contacts the bottom surface of the notch 71, at which time the connecting shaft 10 cannot continue to rotate, so the relative relationship between the movable member 1 and the fixed member 2 is determined, that is, the movable member 1 rotates from the first position to the second position, and the floating member 30 stops rotating along the first direction. When the floating member 30 rotates along the second direction, the connecting shaft 10 may gradually disengage from the notch 71, and in this process the floating member 30 can move along the connecting shaft 10, and after the movable member 1 rotates from the second position to the first position, the floating member 30 still rotates along the second direction, and the floating member 30 disengages from the rotating disk 20, until the floating member 30 contacts the end surface of the blocking rod 70, then the floating member 30 stops moving along the connecting shaft 10, but can still rotate.

[0056] It should be noted that when the movable member 1 rotates from the first position to the second position, the position can be determined by the sensor 72, thereby effectively controlling the floating member 30 to stop rotating. After the movable member 1 rotates from the second position to the first position, since the floating member 30 has been separated from the turntable 20, the movable member 1 will not continue to rotate relative to the fixed member 2. Among them, the sensor 72 can be an in-position switch component, such as an optical coupler switch, or a distance sensor.

[0057] In one embodiment, when the floating member 30 rotates along the second direction, the floating member 30 is used to drive the first peripheral component 3 to work. Figures 2 to 4 As shown, the position adjustment mechanism also includes: a second drive component 80, the second drive component 80 is used to drive the second peripheral component 4 to work; a shell member 90, the shell member 90 is used to connect with the movable member 1, the connecting shaft 10 is connected with the shell member 90, so that the connecting shaft 10 is connected with the movable member 1 through the shell member 90, and the second drive component 80 is arranged on the shell member 90; wherein, the first peripheral component 3 and the second peripheral component 4 are both arranged on the movable member 1, after the connecting shaft 10 is clamped in the notch 71, the floating member 30 stops rotating, the second drive component 80 drives the second peripheral component 4 to work, and after the floating member 30 is in limiting contact with the stop rod 70, the floating member 30 can rotate along the second direction.

[0058] Specifically, when the floating member 30 rotates in the first direction, the floating member 30 is used to drive the movable member 1 to rotate relative to the fixed member 2, that is, the movable member 1 moves from the first position to the second position. When the floating member 30 rotates in the second direction, after the floating member 30 drives the movable member 1 to move from the second position to the first position, it is mainly used to drive the first peripheral component 3 to work. In this embodiment, when the movable member 1 is in the first position, the first peripheral component 3 is in the working position, that is, the floating member 30 rotates in the second direction to realize the operation of the first peripheral component 3. After the movable member 1 is in the second position, the second peripheral component 4 is in the working position, and the second driving component 80 drives the second peripheral component 4 to work.

[0059] In one embodiment, the position adjustment mechanism includes a first drive assembly 60 and a second drive assembly 80. The first drive assembly 60 realizes the rotation of the movable member 1 relative to the fixed member 2 and can be used to drive the first peripheral component 3 to work. The second drive assembly 80 is used to drive the second peripheral component 4 to work. The first drive assembly 60 and the second drive assembly 80 are both arranged on the housing member 90.

[0060] Specific, combined Figures 1 to 3 The first transmission gear 61 is composed of a second bevel gear segment 611 and a transmission gear segment 612, and the floating member 30 is composed of a first bevel gear segment 32 and an output gear segment 33. The second transmission gear 62 is meshed with the transmission gear segment 612 to realize the rotation of the first transmission gear 61, and the second bevel gear segment 611 is meshed with the first bevel gear segment 32 to drive the movement and rotation of the floating member 30. The output gear segment 33 is meshed with the first output gear 64, thereby driving the first peripheral component 3 to work through the first output gear 64.

[0061] It should be noted that a plurality of output gears may be included between the first output gear 64 and the first external component 3, that is, the transmission ratio requirement is met. In this embodiment, the first output gear 64 is meshed with the second output gear 65, the second output gear 65 is meshed with the third output gear 66, and the third output gear 66 is meshed with the fourth output gear 67, and the fourth output gear 67 is connected to the first external component 3, thereby driving the first external component 3 to rotate.

[0062] In one embodiment, the second drive assembly 80 includes a second power source 85, which is drivingly connected to the first gear 81, thereby driving the first gear 81 to rotate. The first gear 81 can be used to drive the second peripheral component 4 to work, and multiple gears can be provided between the first gear 81 and the second peripheral component 4 to meet the transmission ratio. In this embodiment, the first gear 81 is meshed with the second gear 82, the second gear 82 is meshed with the third gear 83, the third gear 83 is meshed with the fourth gear 84, and the fourth gear 84 is connected to the second peripheral component 4, thereby driving the second peripheral component 4 to rotate. Among them, the second power source 85 can be a motor. In this embodiment, the second power source 85 can be an electric motor, and the electric motor realizes forward and reverse rotation.

[0063] An embodiment of the present disclosure further provides a cleaning robot, comprising the above-mentioned position adjustment mechanism.

[0064] In one embodiment, Figure 7 and Figure 8 As shown, the cleaning robot also includes a movable part 1, a fixed part 2, a first peripheral part 3 and a second peripheral part 4, wherein the movable part 1 is rotatably arranged on the fixed part 2, and the first peripheral part 3 and the second peripheral part 4 are arranged on the movable part 1, so that when the movable part 1 rotates relative to the fixed part 2, the first peripheral part 3 and the second peripheral part 4 realize position switching.

[0065] In one embodiment, the first peripheral component 3 and the second peripheral component 4 can be the first cleaning member and the second cleaning member, respectively, and the first cleaning member and the second cleaning member can be a sweeping member and a mopping member, respectively, or both the first cleaning member and the second cleaning member are sweeping members, or both the first cleaning member and the second cleaning member are mopping members. The position adjustment mechanism drives the movable member 1 to rotate relative to the fixed member 2, so that the first cleaning member and the second cleaning member can be located at the working position, that is, after the first cleaning member or the second cleaning member is in the working position, it can be used to clean the surface to be cleaned, such as cleaning the floor.
