[0090] Example implementations are now described with reference to the drawings; however, these implementations are merely examples of implementations provided for descriptive purposes only and, thus, are not limiting in scope. Example implementations can be implemented in various forms. Accordingly, not all of the example implementations described below are necessarily included or required in an implementation and not all problem are associated with the recited example implementations. It is noted that the examples can be used in combination with each other. It is further noted that the examples can be used in combination with other examples not specifically recited.

[0091] Although relative terms are used herein, such as "upper", "lower", to describe one component's relative position to another component of a device, these terms are used herein for convenience only and are not intended to limit the scope of the disclosure or to imply that the device must be in a particular orientation. It is understood that if the device is turned over, the component recited as being on "top" would then be on the "bottom". When a structure is "on" another structure, it can mean that the structure is formed integrally with the other structure or that the structure is "directly" on the other structure or that the structure is "indirectly" on the other structure with intervening structures therebetween.

[0092] The terms "one", "a", "an", "the", "said", are intended to mean one or more of the elements / components / etc.; the terms "including", "has", "having", and "comprising" are intended to be open-ended and to mean that there can be additional elements / components / etc. other than those listed; the terms "first", "second", and the like, are merely used to identify one of the elements / components / etc., and are not meant to limit the number of such elements / components / etc.

[0093] As shown in Figures 1 to 14 The present disclosure first provides a cleaning device, which can include: a carrying device and a cleaning device. The cleaning device can be a sweeping robot, a scrubber, a vacuum cleaner, a sweeping and mopping integrated machine, a window cleaning robot, etc. The cleaning device can include a cleaning part, which can be a roller brush, an edge brush, a water outlet, a mopping part, a window cleaning part, etc., for cleaning a surface to be cleaned, which can be a ground surface, a surface of a step 3, etc.

[0094] The carrying device can be a stair climbing machine, which can have the functions of climbing up and / or down a step 3, but is not limited thereto, and the carrying device is other machines with carrying functions. As shown in Figure 1 The carrying device can include: a main body part 1 and a side support part 2. The main body part 1 can be provided with a carrying structure 11, and the cleaning device can be located in the carrying structure 11, so that the carrying device can carry the cleaning device to move from a first surface 38 to a second surface 39 or from the second surface 39 to the first surface 38, and the second surface 39 can be higher than the first surface 38, so as to clean surfaces of different heights by using the cleaning device. For example: the carrying device can carry the cleaning device to climb up and / or down a step 3, and the first surface 38 and the second surface 39 can be surfaces of different steps 3, respectively, so as to clean the surfaces of the steps 3 or the ground surfaces of different floors, etc.

[0095] It should be noted that when the carrying device moves from the current first surface 38 to the current second surface 39 in the climbing process, the current second surface 39 becomes the first surface 38 in the next climbing process of the carrying device, and the surface above the current second surface 39 becomes the second surface 39 in the next climbing process of the carrying device. When the carrying device moves from the current second surface 39 to the current first surface 38 in the climbing-down process, the current first surface 38 becomes the second surface 39 in the next climbing-down process of the carrying device, and the surface below the current first surface 38 becomes the first surface 38 in the next climbing-down process of the carrying device.

[0096] The bearing structure 11 can be located on the bottom surface of the main body 1, so that the distance between the bearing structure 11 and the surface to be cleaned is closer, facilitating the cleaning device to clean the surface to be cleaned. The main body 1 can also have a containing cavity 12, and the cleaning device can be located in the containing cavity 12, so as to limit and protect the cleaning device by the inner wall of the containing cavity 12 and the bearing structure 11, thereby reducing the probability of the cleaning device being separated from the bearing structure 11, and avoiding the damage of the cleaning device caused by the collision between the cleaning device and the objects in the external environment.

[0097] In some embodiments, the main body 1 itself can also have a cleaning function, that is, the bottom surface of the main body 1 can also be directly provided with a cleaning device, so that the main body 1 and the cleaning device form an integral structure, which can realize the functions of moving from the first surface 38 to the second surface 39 or moving from the second surface 39 to the first surface 38 and cleaning the surface to be cleaned. In this way, the integration of the main body 1 can be improved, and additional cleaning devices no longer need to be added, and the bearing structure 11 for bearing other cleaning devices no longer needs to be provided on the main body 1.

[0098] The side support 2 can be connected with the main body 1, and the side support 2 can move from the first surface 38 to the second surface 39 or move from the second surface 39 to the first surface 38. When the bearing device moves from the first surface 38 to the second surface 39 or moves from the second surface 39 to the first surface 38, the side support 2 can support the main body 1 to send the main body 1 to the surface to be reached, and when the main body 1 reaches the surface to be reached, the side support 2 moves to the surface with the main body 1. That is, the main body 1 and the side support 2 can move alternately to achieve the purpose of moving the bearing device from the first surface 38 to the second surface 39 or moving the bearing device from the second surface 39 to the first surface 38.

[0099] Alternatively, when the bearing device moves from the first surface 38 to the second surface 39 or moves from the second surface 39 to the first surface 38, the side support 2 can first move to the surface to be reached, and when the side support 2 reaches the surface to be reached, the main body 1 is driven to move to the surface. That is, the side support 2 and the main body 1 can move alternately to achieve the purpose of moving the bearing device from the first surface 38 to the second surface 39 or moving the bearing device from the second surface 39 to the first surface 38.

[0100] Alternatively, when the bearing device moves from the first surface 38 to the second surface 39 or moves from the second surface 39 to the first surface 38, the main body 1 and the side support 2 can move simultaneously to simultaneously move to the surface to be reached.

[0101] In some embodiments, as shown in FIG. 1, the main body 1 can have a bearing structure 11, and the bearing structure 11 can be provided with a cleaning device. Figures 2 to 12As shown, the side support part 2 can include a first support module 21. The first support module 21 can be configured to support the first overhanging part 37 when the side support part 2 is located on the second surface 39 and has the first overhanging part 37.

[0102] When the width of the second surface 39 is wide, the side support part 2 does not have the first overhanging part 37 when located on the step 3, and the side support part 2 can provide support so that the load-bearing device can keep the center of gravity stable on the second surface 39, so that the load-bearing device has high safety and stability when working on the wide second surface 39.

[0103] When the width of the second surface 39 is narrow, the side support part 2 will have the first overhanging part 37 when located on the second surface 39, causing the center of gravity of the load-bearing device on the second surface 39 to be unstable, and at this time the first support module 21 can be used to support the first overhanging part 37, so that the center of gravity of the load-bearing device on the second surface 39 remains stable, so that the load-bearing device also has high safety and stability when working on the narrow second surface 39. Therefore, the load-bearing device can be suitable for second surfaces 39 of different widths and have high safety and stability when working on second surfaces 39 of different widths.

[0104] In addition, since the first support module 21 can support the first overhanging part 37, the load-bearing device can be suitable for first surfaces 38 and second surfaces 39 with different height differences, and can ensure that the load-bearing device can have high stability when located on the second surface 39 with different height differences from the first surface 38, thereby improving the safety and stability of the load-bearing device when working on the second surface 39 with different height differences from the first surface 38.

[0105] The first support module 21 can include a first driving part 211 and a first support rod 212. The first support rod 212 can be connected with the first driving part 211, and the first driving part 211 can drive the first support rod 212 to support the first surface 38 when the side support part 2 is located on the second surface 39.

[0106] The first driving part 211 can be provided to automatically support the first overhanging part 37 when the side support part 2 has the first overhanging part 37. At the same time, the first support rod 212 can improve the support force and structural strength of the first support module 21, and ensure the support effect of the first support module 21 on the side support part 2. Furthermore, the first support rod 212 can be freely adjusted in length according to the different height differences between the first surface 38 and the second surface 39, so that the first support module 21 can be suitable for providing good support to the side support part 2 under the condition that the first surface 38 and the second surface 39 have different height differences.

[0107] In some embodiments, as shown in FIG. 2A, the first support rod 212 can have a first support end 2121, and the first driving part 211 can drive the first support end 2121 to move towards the first surface 38, so that the first support rod 212 can be supported on the first surface 38. Figure 2 、 Figure 3 、 Figures 5 to 9 The first support rod 212 can be a single rod structure, and the first support end 2121 can be located at one end of the single rod structure close to the first surface 38. The first driving part 211 can drive the entire first support rod 212 to move towards the first surface 38, so that the first support end 2121 moves towards the first surface 38, thereby enabling the first support rod 212 to be supported on the first surface 38.

[0108] The first support rod 212 can also be a telescopic structure, that is, the first support rod 212 can be formed by a fixed rod and a telescopic rod, the telescopic rod can move relative to the fixed rod, and the first support end 2121 can be located at one end of the telescopic rod close to the first surface 38. The first driving part 211 can be connected with the telescopic rod, and the first driving part 2111 drives the telescopic rod to move towards the first surface 38, so that the first support end 2121 moves towards the first surface 38, thereby enabling the first support rod 212 to be supported on the first surface 38.

[0109] The first support rod 212 can also be a telescopic structure, that is, the first support rod 212 can be formed by a fixed rod and a telescopic rod, the telescopic rod can move relative to the fixed rod, and the first support end 2121 can be located at one end of the telescopic rod close to the first surface 38. The first driving part 211 can be connected with the telescopic rod, and the first driving part 2111 drives the telescopic rod to move towards the first surface 38, so that the first support end 2121 moves towards the first surface 38, thereby enabling the first support rod 212 to be supported on the first surface 38.

[0110] The first support rod 212 can also be a telescopic structure, that is, the first support rod 212 can be formed by a fixed rod and a telescopic rod, the telescopic rod can move relative to the fixed rod, and the first support end 2121 can be located at one end of the telescopic rod close to the first surface 38. The first driving part 211 can be connected with the telescopic rod, and the first driving part 2111 drives the telescopic rod to move towards the first surface 38, so that the first support end 2121 moves towards the first surface 38, thereby enabling the first support rod 212 to be supported on the first surface 38.

[0111] But not limited to this, the first support rod 212 is not limited to the three structures listed above, and can also be other structures, which can be selected and arranged according to actual needs, which are all within the protection scope of the present disclosure.

[0112] In some embodiments, when the side support part 2 needs to climb or descend the steps 3, and the height of the steps 3 changes, the first driving part 211 can drive the first support end 2121 to move away from the first surface 38, so as to release the support of the first support rod 212 to the first overhanging part 37. It can be understood that the first driving part 211 can drive the first support end 2121 to move in a straight line direction, so that the first support end 2121 moves away from the first surface 38, so as to retract the first support rod 212, thereby releasing the support of the first support rod 212 to the first overhanging part 37. When the side support part 2 reaches the next step 3, the first driving part 211 is used again to drive the first support end 2121 to move towards the first surface 38 at this time, so as to support the first overhanging part 37 again by the first support rod 212.

[0113] When the side support part 2 needs to move from the first surface 38 to the second surface 39 or from the second surface 39 to the first surface 38, and the height difference between the first surface 38 and the second surface 39 does not change, since the first support rod 212 does not need to change the support height when it supports next time, the first support rod 212 can not be retracted, and the first support rod 212 that has been extended can be directly used to support next time. However, not limited thereto, when the side support part 2 needs to move from the first surface 38 to the second surface 39 or from the second surface 39 to the first surface 38, and the height difference between the first surface 38 and the second surface 39 does not change, the first driving part 211 can be used to drive the first support end 2121 to move away from the first surface 38, so as to release the support of the first support rod 212 to the first overhanging part 37. When the side support part 2 reaches the next second surface 39, the first driving part 211 is used again to drive the first support end 2121 to move towards the first surface 38 at this time, so as to support the first overhanging part 37 again by the first support rod 212.

[0114] In some embodiments, as shown in Figures 5 to 12 The side support part 2 can further include a body part 23. The body part 23 can include a shell and a containing space, and the containing space can be enclosed by the shell. The first support module 21 can be arranged in the containing space, so that the first support module 21 is protected by the shell, and damage caused by collision with other structures in the external environment can be avoided. However, not limited thereto, the first support module 21 can also not be arranged in the containing space, that is, the first support module 21 can also be arranged on the outer surface of the shell.

[0115] As shown in Figure 9As shown, the first support module 21 further comprises a first guide sleeve 214. The first guide sleeve 214 can be mounted on the body portion 23, and the first guide sleeve 214 can be sleeved on at least part of the outer circumferential surface of the first support rod 212 to guide the movement of the first support rod 212, so that the first support rod 212 can always move along the correct movement direction.

[0116] The outer circumferential surface of the first support rod 212 can be provided with a first thread. The inner circumferential surface of the first guide sleeve 214 can be provided with a second thread engaged with the first thread. The first driving portion 211 can drive the first guide sleeve 214 or the first support rod 212 to rotate, so that the first support rod 212 moves towards the first surface 38. Alternatively, the first driving portion 211 can drive the first guide sleeve 214 or the first support rod 212 to rotate in the opposite direction, so that the first support rod 212 moves away from the first surface 38.

[0117] By providing the first thread and the second thread, the first thread and the second thread can be used for self-locking, which can prevent the first support rod 212 from moving during the support of the opposite support portion 2, thereby improving the support force and stability of the first support rod 212. At the same time, by providing the first thread and the second thread, the movement stroke of the first support rod 212 can be more conveniently and accurately controlled, further improving the support effect of the first support rod 212 on the opposite support portion 2.

[0118] At least part of the outer circumferential surface of the first guide sleeve 214 can be provided with a first tooth portion 2141. The first driving portion 211 can include a first driving piece 2111 and a first transmission piece 2112. The first transmission piece 2112 can be connected with the first driving piece 2111, and the outer circumferential surface of the first transmission piece 2112 can be provided with a second tooth portion 2113 engaged with the first tooth portion 2141. The first driving piece 2111 can drive the first transmission piece 2112 to rotate. When the first transmission piece 2112 rotates, the first transmission piece 2112 can drive the first tooth portion 2141 to move through the second tooth portion 2113, thereby driving the first guide sleeve 214 to rotate. In this way, the first support rod 212 can be driven to move towards or away from the first surface 38 through the cooperation of the first thread and the second thread.

[0119] The first transmission member 2112 can include a plurality of gears, and the plurality of gears can be meshed with each other. The gear ratio of the plurality of gears can be adjusted as needed to adjust the rotation speed of the first guide sleeve 214, so as to adjust the movement speed of the first support rod 212. Alternatively, when the relative position between the first driving member 2111 and the second tooth portion 2113 is far, the arrangement position of the plurality of gears can be adjusted according to the position of the first driving member 2111 and the second tooth portion 2113, so as to ensure that the driving force output by the first driving member 2111 can be transmitted to the second tooth portion 2113 through the plurality of gears. However, the first transmission member 2112 can also include only one gear, which can be selected according to actual conditions, and this is within the protection scope of the present disclosure.

[0120] In some embodiments of the present disclosure, as shown in Figure 2 and Figure 4 The first driving portion 211 can drive the first support rod 212 to rotate in the first direction X, so as to rotate the first support end 2121 to the first surface 38, so that the first support rod 212 is supported on the first surface 38. For example, the initial state of the first support rod 212 can be retracted in the side support portion 2, and the first driving portion 211 can be used to drive the first support rod 212 to rotate in the first direction X, so that the first support rod 212 extends out of the side support portion 2, and the first support rod 212 is supported on the first surface 38.

[0121] In addition, the first driving portion 211 can drive the first support rod 212 to rotate in the direction opposite to the first direction X, so that the first support end 2121 is away from the first surface 38, so as to release the support of the first support rod 212 on the first overhanging portion 37. For example, the first driving portion 211 can be used to drive the first support rod 212 to rotate in the direction opposite to the first direction X, so that the first support rod 212 returns to the initial state and is retracted in the side support portion 2, so as to release the support of the first support rod 212 on the first overhanging portion 37.

[0122] In some embodiments, as shown in Figures 5 to 11 The first support rod 212 can include a first support block 2122. The first support block 2122 can be arranged on the first support end 2121, and the first support block 2122 can be connected with the first support end 2121. The contact area between the first support block 2122 and the first surface 38 can be greater than the contact area between the first support end 2121 and the first surface 38. In this way, when the first support block 2122 is in contact with the first surface 38, compared with directly contacting the first surface 38 by using the first support end 2121, the first support block 2122 has a larger contact area, so that more stable support can be provided, and the pressure applied by the first support rod 212 on the first surface 38 can be reduced, so as to avoid damaging the first surface 38 by the first support rod 212.

[0123] As shown in Figure 10 The first support module 21 can further include a first detector 213. The first detector 213 can be configured to detect the relative position between the first support end 2121 and the first surface 38. When the first support end 2121 is in contact with the first surface 38, the first driving part 211 is controlled to stop providing the driving force to the first support end 2121. In this way, the interaction force between the first support end 2121 and the first surface 38 can be reduced, and the damage to the first support rod 212 and / or the first surface 38 can be reduced.

[0124] When the outer circumferential surface of the first support rod 212 is provided with a first thread, and the inner circumferential surface of the first guide sleeve 214 is provided with a second thread, if the driving force is continuously provided to the first support end 2121 when the first support end 2121 is in contact with the first surface 38, the first support end 2121 will not continue to move, and the driving force will be concentrated between the first thread and the second thread, causing the first thread and the second thread to be locked, affecting the subsequent movement of the first support rod 212 and the normal operation of the bearing device. In this embodiment, the first detector 213 is provided to avoid the first driving part 211 providing the driving force to the first support end 2121 when the first support end 2121 is in contact with the first surface 38, so that the problem of the first thread and the second thread being locked can be effectively avoided, the subsequent movement of the first support rod 212 can be ensured, and the normal operation of the bearing device can be ensured.

[0125] The first detector 213 can be installed on the first support end 2121. When the first detector 213 is in contact with the first surface 38, the first driving part 211 is controlled to stop providing the driving force to the first support end 2121. In this way, the distance between the first detector 213 and the first support end 2121 can be closer, and the accuracy of the first detector 213 detecting the relative position between the first support end 2121 and the first surface 38 can be improved.

[0126] When the first support rod 212 includes the first support block 2122, the first detector 213 can be installed on the side of the first support block 2122 facing the first surface 38. In this way, the distance between the first detector 213 and the first support block 2122 can be closer, and the accuracy of the first detector 213 detecting the relative position between the first support block 2122 and the first surface 38 can be improved.

[0127] As shown in Figure 10 and Figure 11As shown, one side of the first support block 2122 facing the first surface 38 can be provided with a first mounting groove 2123, and the first detector 213 can be arranged in the first mounting groove 2123. When the first support block 2122 is in contact with the first surface 38, the first detector 213 is in contact with the first surface 38. In this way, the first detector 213 can be provided with a mounting space, avoiding the first detector 213 protruding from the first support block 2122 as a whole, so that the probability of damage to the first detector 213 due to pressure when the first support block 2122 is in contact with the first surface 38 can be reduced.

[0128] In some embodiments, the bearing device can further include a first controller. The first detector 213 can be connected with the first controller, and the first driving member 2111 can be in communication connection with the first controller. When the first detector 213 detects that the first support end 2121 is in contact with the first surface 38, a detection signal can be sent to the first controller, and the first controller can control the first driving member 2111 to stop providing driving force to the first support end 2121 after receiving the detection signal.

[0129] However, the bearing device can also not be provided with the first controller, and the first detector 213 can have both detection and control functions, and can be in communication connection with the first driving member 2111. When the first detector 213 detects that the first support end 2121 is in contact with the first surface 38, the first driving member 2111 can be directly controlled to stop providing driving force to the first support end 2121.

[0130] The first detector 213 can be a microswitch. However, the first detector 213 can also be an optical coupling sensor, a Hall sensor, etc., which can be selected and arranged according to actual conditions, and all of these are within the protection scope of the present disclosure.

[0131] In some embodiments, as shown, Figures 5 to 12 The first support module 21 can further include a second detector 215. The second detector 215 can be configured to detect the position of the first support end 2121 moving away from the first surface 38. When the first support end 2121 moves away from the first surface 38 to a preset position, the first driving part 211 can be controlled to stop providing driving force to the first support end 2121. In this way, the first support end 2121 can be prevented from colliding with other structural members in the side support part 2 due to the first driving part 211 continuously providing driving force to the first support end 2121 when the first support end 2121 moves away from the first surface 38 to the preset position.

[0132] And, when the outer circumferential surface of the first support rod 212 is provided with a first thread, and the inner circumferential surface of the first guide sleeve 214 is provided with a second thread, if the first driving part 211 continues to provide driving force to the first support end 2121 when the first support end 2121 moves to the preset position in the direction away from the first surface 38, the applied driving force may be concentrated between the first thread and the second thread, causing the first thread and the second thread to be locked, affecting the subsequent movement of the first support rod 212, and thus affecting the normal work of the bearing device. Therefore, by providing the second detector 215, the first driving part 211 can be prevented from providing driving force to the first support end 2121 when the first support end 2121 moves to the preset position, which can effectively prevent the first thread and the second thread from being locked, ensure the subsequent movement of the first support rod 212, and ensure the normal work of the bearing device.

[0133] The second detector 215 can be installed at the preset position, and the second detector 215 can be configured to control the first driving part 211 to stop providing driving force to the first support end 2121 when the first support end 2121 moves away from the first surface 38 and contacts the second detector 215. In this way, the distance between the second detector 215 and the preset position can be closer, so as to improve the accuracy of detection by the second detector 215.

[0134] In some embodiments, the bearing device can further include a second controller. The first controller and the second controller can be the same controller, but are not limited to this, and the second controller and the first controller can also be independent controllers.

[0135] The second detector 215 can be connected to the second controller, and the first driving part 2111 can be connected to the second controller. When the second detector 215 detects that the first support end 2121 moves to the preset position, a detection signal can be sent to the second controller, and the second controller can control the first driving part 2111 to stop providing driving force to the first support end 2121 after receiving the detection signal.

[0136] However, the bearing device can also not be provided with a second controller, and the second detector 215 can have both detection and control functions, and can be in communication connection with the second driving part. When the second detector 215 detects that the first support end 2121 moves to the preset position, the first driving part 2111 can be directly controlled to stop providing driving force to the first support end 2121.

[0137] The second detector 215 can be a micro switch. However, the second detector 215 can also be an optical coupling sensor, a Hall sensor, etc., which can be selected and set according to actual conditions, and all of these are within the protection scope of the present disclosure.

[0138] In some embodiments, as shown in Figures 5 to 12 The first support module 21 can further include a first guide rod 216. The first guide rod 216 can be arranged in parallel with the first support rod 212, and the first guide rod 216 can be connected with the first support rod 212. The first guide rod 216 is configured to guide the movement of the first support rod 212, so that the first support rod 212 can always move in the correct direction of movement.

[0139] As shown in Figure 12 The first support module 21 can further include a first connecting block 217. The first connecting block 217 can have a first through hole and a second through hole, the first support rod 212 can pass through the first through hole, and the first guide rod 216 can pass through the second through hole, so that the first support rod 212 and the first guide rod 216 are connected.

[0140] As shown in Figures 5 to 12 The first support module 21 can further include a second connecting block 218. The second connecting block 218 can be fixedly connected with the first support rod 212 and the first guide rod 216, so that the first support rod 212 and the first guide rod 216 can move synchronously relative to the first connecting block 217, so as to further improve the connection stability of the first guide rod 216 and the first support rod 212, and further improve the guiding ability of the first guide rod 216.

[0141] The second connecting block 218 can be away from the first support end 2121 relative to the first connecting block 217, so as to avoid the position interference between the second connecting block 218 and the first support end 2121, but is not limited thereto.

[0142] The first support module 21 can further include a second guide sleeve 219. The second guide sleeve 219 can be installed on the body portion 23, and can be sleeved on at least part of the outer circumferential surface of the first guide rod 216, so as to guide the movement of the first guide rod 216, thereby further improving the accuracy of the movement direction of the first support portion.

[0143] In other embodiments, the first support rod 212 can be fixedly connected with the first connecting block 217 through the first through hole, the first guide rod 216 can be slidingly connected with the first connecting block 217 through the second through hole, and the first support rod 212 and the first connecting block 217 can move relative to the first guide rod 216, so as to guide the movement of the first connecting block 217 by the first guide rod 216, and indirectly guide the movement of the first support rod 212 by the first connecting block 217.

[0144] In some embodiments of the present disclosure, as shown in Figure 13As shown, the main body 1 comprises a second support module 13. The second support module 13 can be configured to support the second overhanging part when the main body 1 is located on the second surface 39 and has the second overhanging part. In this way, the second support module 13 and the first support module 21 can be used in cooperation to improve the stability of the bearing device.

[0145] The second support module 13 can comprise a second driving part 131 and a second support rod 132. The second support rod 132 can be connected with the second driving part 131, and the second driving part 131 can drive the second support rod 132 to support the first surface 38. By providing the second driving part 131, the main body 1 can be automatically supported when the second overhanging part is provided. At the same time, by providing the second support rod 132, the support force and structural strength of the second support module 13 can be improved, so as to ensure the support effect of the second support module 13 on the main body 1. Moreover, by providing the second support rod 132, the support length of the second support rod 132 can be freely adjusted according to the different height differences between the first surface 38 and the second surface 39, so that the second support module 13 can be applied to provide good support to the main body 1 in the case that the first surface 38 and the second surface 39 have different height differences.

[0146] In some embodiments, the second support rod 132 can have a second support end, and the second driving part 131 can drive the second support end to move towards the second support surface, so that the second support rod 132 supports the second support surface. It can be understood that the second driving part 131 can drive the second support end to move in a straight line direction, so that the second support end reaches the second support surface, so that the second support rod 132 can support the second support surface.

[0147] In some embodiments, when the main body 1 needs to be moved from the first surface 38 to the second surface 39 or from the second surface 39 to the first surface 38, and the height difference between the first surface 38 and the second surface 39 changes, the second driving part 131 can drive the second support end to move away from the second support surface, so as to release the support of the second support rod 132 on the second overhanging part. When the main body 1 reaches the next second surface 39, the second driving part 131 is used again to drive the second support end to move towards the first surface 38 at this time, so as to use the second support rod 132 to support the second overhanging part again.

[0148] When the main body 1 needs to move from the first surface 38 to the second surface 39 or from the second surface 39 to the first surface 38, and the height difference between the first surface 38 and the second surface 39 does not change, the second support rod 132 does not need to change the support height when it is used for the next support, so the second support rod 132 can not be retracted, and the second support rod 132 that has been extended can be directly used for the next support. However, when the main body 1 needs to move from the first surface 38 to the second surface 39 or from the second surface 39 to the first surface 38, and the height difference between the first surface 38 and the second surface 39 does not change, the second driving part 131 can be used to drive the second support end to move away from the first surface 38, so as to release the support of the second support rod 132 on the second overhanging part. When the main body 1 reaches the next second surface 39, the second driving part 131 is used again to drive the second support end to move towards the first surface 38 at this time, so as to support the second overhanging part again by using the second support rod 132.

[0149] In some embodiments, the second driving part 131 can drive the second support rod 132 to rotate in the first direction X, so as to rotate the second support end to the first surface 38, and support the second support rod 132 on the first surface 38.

[0150] In addition, the second driving part 131 can drive the second support rod 132 to rotate in the direction opposite to the first direction X, so as to move the second support end away from the first surface 38, and release the support of the first support rod 212 on the first overhanging part 37.

[0151] In some embodiments of the present disclosure, as shown in Figure 5 and Figure 6 In order to avoid the collision with the edge of the second surface 39 when the side support part 2 moves from the first surface 38 to the second surface 39 or from the second surface 39 to the first surface 38, a notch 231 can be arranged on the side of the body part 23 facing the edge of the second surface 39, so as to avoid the edge of the second surface 39 by using the notch 231. However, when the side of the body part 23 facing the edge of the second surface 39 is provided with the notch 231, the body part 23 cannot be supported at the position of the notch 231, which leads to the decrease of the support strength of the side support part 2.

[0152] In the embodiment, the side support part 2 can further comprise a swing lever 24. The swing lever 24 can be connected with the body part 23, and the swing lever 24 can have a third support end 241. When the side support part 2 is in a static state, the third support end 241 can be in a first position, at which the third support end 241 is in contact with the surface on which the side support part 2 is located, and at least part of the third support end 241 protrudes from one side of the edge of the body part 23 facing the second surface 39. When the side support part 2 climbs the step 3 and / or descends the step 3, the third support end 241 can be in a second position, which is away from the edge of the second surface 39 relative to the first position.

[0153] It should be noted that when the carrying device is in the climbing process, the surface on which the side support part 2 is located at the moment can be considered as the first surface 38, at which the third support end 241 is in contact with the first surface 38, and at least part of the third support end 241 protrudes from one side of the edge of the body part 23 facing the second surface 39 at the moment; when the carrying device is in the descending process, the surface on which the side support part 2 is located at the moment can be considered as the second surface 39 at the moment, at which the third support end 241 is in contact with the second surface 39 at the moment, and at least part of the third support end 241 protrudes from one side of the edge of the body part 23 facing the second surface 39 at the last moment.

[0154] In this way, when the side support part 2 is in the static state, the swing lever 24 can be used to support the side support part 2 at the position of the gap 231 of the body part 23, so as to make up for the defect that the body part 23 cannot support at the position of the gap 231, thereby improving the support strength of the side support part 2. Meanwhile, when the side support part 2 moves from the first surface 38 to the second surface 39 or moves from the second surface 39 to the first surface 38, the swing lever 24 can be away from the edge of the second surface 39, so as to avoid the swing lever 24 and the edge of the second surface 39, thereby avoiding collision between the swing lever 24 and the edge of the second surface 39.

[0155] When the first surface 38 and the second surface 39 are surfaces of the step 3, the first surface 38 and the second surface 39 can be tread surfaces of the step 3, at which the gap 231 can face the kick surface 32 of the step 3. Meanwhile, the swing lever can protrude from one side of the edge of the body part 23 facing the kick surface 32 of the step 3. At this time, the gap 231 can avoid the kick surface 32, thereby avoiding collision between the gap 231 and the kick surface 32. Meanwhile, when the swing lever 24 is in the second position, the kick surface 32 can also be avoided.

[0156] It should be noted that, as shown in Figures 2 to 4 The step 3 can have a tread surface 31 and a kick surface 32. The tread surface 31 of the step 3 refers to a surface extending horizontally in the step 3, and the kick surface 32 of the step 3 refers to a surface extending vertically in the step 3, i.e., the kick surface 32 of the step 3 connects the first surface 38 and the second surface 39 in the step 3.

[0157] In some embodiments, the rocker arm 24 may be rotatably connected to the body portion 23, and the rocker arm 24 may rotate relative to the body portion 23 to switch the third support end 241 between a first position and a second position.

[0158] The side support 2 may further include a third drive unit 25. The third drive unit 25 may be connected to the rocker arm 24 for driving the rocker arm 24 to rotate relative to the main body 23.

[0159] like Figure 5 , Figure 6 and Figure 13 As shown, the third drive unit 25 may include a third drive member 251, a first dial 252, and a pulling mechanism 253. The first dial 252 is mounted on the main body 23, and the third drive member 251 can drive the first dial 252 to rotate. One end of the pulling mechanism 253 can be connected to the end face or outer peripheral surface of the first dial 252, and the other end of the pulling mechanism 253 is connected to the rocker arm 24. When the first dial 252 rotates, it can pull one end of the pulling mechanism 253, causing the other end of the pulling mechanism 253 to pull the rocker arm 24, thereby causing the rocker arm 24 to rotate relative to the main body 23.

[0160] The pulling mechanism 253 can be a pull rope to reduce the manufacturing cost of the pulling mechanism 253. However, it is not limited to this. The pulling mechanism 253 can also be a pull rod, a connecting rod structure, etc., which can be selected and set according to the actual situation, and all of these are within the protection scope of this disclosure.

[0161] In some embodiments, at least a portion of the outer peripheral surface of the first dial 252 may be provided with a first protrusion 2521. The third drive unit 25 may further include a second dial 254. The second dial 254 may be mounted on the body unit 23 and may be connected to the third drive member 251. The third drive member 251 is capable of driving the second dial 254 to rotate.

[0162] At least a portion of the outer peripheral surface of the second dial 254 may be provided with a second protrusion 2541. When the second dial 254 rotates, the second protrusion 2541 can abut against the first protrusion 2521 to drive the first dial 252 to rotate.

[0163] The first protruding portion 2521 can include at least one first protruding block 2522, and the second protruding portion 2541 can include one second protruding block 2542. When the second dial 254 rotates, the second protruding block 2542 can abut against one first protruding block 2522. Since the third driving member 251 continuously drives the second dial 254 to rotate, the swing lever 24 does not need to continuously rotate, but only needs to move the third support end 241 from the first position to the second position or from the second position to the first position. Thus, through the above arrangement, when the first protruding block 2522 abuts against the second protruding block 2542, the first dial 252 can rotate with the second dial 254. When the first dial 252 and the second dial 254 rotate through a certain angle, the first protruding block 2522 and the second protruding block 2542 are separated, at which time the third support end 241 moves from the first position to the second position or from the second position to the first position, and the first dial 252 does not continue to rotate. Thus, through the above arrangement, the continuous rotation of the second dial 254 can be converted into the intermittent rotation of the first dial 252 to avoid continuous rotation of the swing lever 24.

[0164] However, the second protruding portion 2541 can also have other numbers of second protruding blocks 2542, which can be arranged according to actual needs.

[0165] In other embodiments, the first dial 252 can not be provided with the first protruding portion 2521, and the second dial 254 can not be provided with the second protruding portion 2541. The outer circumferential surface of the first dial 252 and the outer circumferential surface of the second dial 254 can be in contact, and the second dial 254 can drive the first dial 252 to rotate through the friction between the outer circumferential surface of the first dial 252 and the outer circumferential surface of the second dial 254.

[0166] In the present embodiment, the outer circumferential surface of the first dial 252 can have a recessed portion. When the recessed portion is opposite to the outer circumferential surface of the second dial 254, the outer circumferential surface of the second dial 254 cannot be in contact with the surface of the recessed portion, so that the second dial 254 cannot drive the first dial 252 to rotate through the friction. Thus, through the above arrangement, the continuous rotation of the second dial 254 can be converted into the intermittent rotation of the first dial 252 to avoid continuous rotation of the swing lever 24.

[0167] In some embodiments, the side support part 2 can further comprise a reset member 26. The reset member 26 can be arranged on the body part 23. Moreover, the reset member 26 can be configured to drive the first dial 252 to return to the initial position after the second dial 254 drives the first dial 252 to rotate, so as to drive the swing lever 24 to rotate, so that the third support end 241 returns to the initial position. For example, when the second dial 254 drives the first dial 252 to rotate, the first dial 252 can drive the swing lever 24 to rotate so that the third support end 241 switches from the first position to the second position; the reset member 26 can drive the first dial 252 to rotate in the opposite direction, so that the third support end 241 returns from the second position to the initial first position. Alternatively, when the second dial 254 drives the first dial 252 to rotate, the first dial 252 can drive the swing lever 24 to rotate so that the third support end 241 switches from the second position to the first position; the reset member 26 can drive the first dial 252 to rotate in the opposite direction, so that the third support end 241 returns from the first position to the initial second position.

[0168] The reset member 26 can be an elastic member, for example, the reset member 26 can be a spring or the like. One end of the elastic member can be fixed to the body part 23, and the other end can be fixed to the first dial 252. When the second dial 254 drives the first dial 252 to rotate, the elastic member is elastically deformed, so that the elastic member has a restoring force inside. The reset member 26 can drive the first dial 252 to return to the initial position through the restoring force.

[0169] However, the reset member 26 can also not be an elastic member, but can be a driving member such as a motor or an air cylinder, to directly drive the first dial 252 to rotate in the opposite direction, so that the first dial 252 returns to the initial position.

[0170] In some embodiments, the side support part 2 can further comprise a first limiting structure 27. The first limiting structure 27 can be arranged on the body part 23, and the first limiting structure 27 can be limited in cooperation with the pull rope, so as to limit the pull rope by the first limiting structure 27. In this way, the pulling direction of the pull rope can be fixed by the first limiting structure 27, and at the same time, the normal work of other components can be avoided due to the random swinging of the pull rope on the body part 23.

[0171] The first limiting structure 27 can be provided with a limiting groove, and at least part of the pull rope can be located in the limiting groove, so that the pull rope is limited in cooperation with the first limiting structure 27. In this way, the limiting ability of the first limiting structure 27 to the pull rope can be improved, and the probability of disengagement of the pull rope from the first limiting structure 27 can be reduced.

[0172] The first limiting structure 27 can be located on the side of the body portion 23 facing the second surface 39, and the limiting slot can be located on the side of the first limiting structure 27 away from the body portion 23. In this way, the pull rope can be limited in the limiting slot, and the pull rope can be used to pull the swing lever 24, so that the third support end 241 is switched from the first position to the second position.

[0173] Alternatively, the first limiting structure 27 can be located on the side of the body portion 23 facing the second surface 39, and the limiting slot can be located on the side of the first limiting structure 27 away from the body portion 23. In this way, the pull rope can be limited in the limiting slot, and the pull rope can be used to pull the swing lever 24, so that the third support end 241 is switched from the second position to the first position.

[0174] In some embodiments, the side support portion 2 can further include a second limiting structure 28. The second limiting structure 28 can include a first limiting block 281, which can be arranged on the body portion 23, and when the third support end 241 is in the first position, the first limiting block 281 can be located on the side of the body portion 23 facing the edge of the second surface 39, to limit the rotation range of the swing lever 24. That is, when the swing lever 24 rotates towards the first limiting block 281, the third support end 241 can be switched from the second position to the first position. The first limiting block 281 can limit the rotation range of the swing lever 24, to ensure that the third support end 241 can accurately reach the first position. At the same time, it can also avoid the problem of collision with other components due to the continuous rotation of the swing lever 24.

[0175] The second limiting structure 28 can further include a second limiting block 282. The second limiting block 282 can be arranged on the body portion 23, and when the third support end 241 is in the second position, the second limiting block 282 can be located on the side of the body portion 23 facing the edge of the second surface 39, to limit the rotation range of the swing lever 24. That is, when the swing lever 24 rotates towards the second limiting block 282, the third support end 241 can be switched from the first position to the second position. The second limiting block 282 can limit the rotation range of the swing lever 24, to ensure that the third support end 241 can accurately reach the second position. At the same time, it can also avoid the problem of collision with other components due to the continuous rotation of the swing lever 24.

[0176] The second limiting structure 28 can further include a third limiting block 283. The third limiting block 283 can be arranged on the side of the swing lever 24 away from the main body 1 to avoid the swing lever 24 moving away from the main body 1. The two ends of the third limiting block 283 can be connected with the first limiting block 281 and the second limiting block 282 to form an integrated structure of the third limiting block 283, the first limiting block 281 and the second limiting block 282, so as to improve the integration of the second limiting structure 28.

[0177] The second limiting structure 28 can further include a limiting detector 284. The limiting detector 284 can be arranged on the body 23, and the limiting detector 284 can be configured to detect whether the third supporting end 241 is in the first position.

[0178] The limiting detector 284 can be installed on the first limiting block 281 to further improve the integration of the second limiting structure 28. The limiting detector 284 can be a contact sensor, such as a microswitch, an optical coupling sensor, etc. The limiting detector 284 can be configured to determine that the third supporting end 241 is in the first position when the swing lever 24 contacts the limiting detector 284.

[0179] However, the limiting detector 284 can also be a non-contact sensor, such as a Hall sensor, etc. The selection and arrangement can be made according to actual needs, which are all within the protection scope of the present disclosure.

[0180] As shown in FIG. 1, Figure 13 The side supporting part 2 can further include a climbing driving member 29. The climbing driving member 29 can be installed on the main body 1 or the body 23 to drive the side supporting part 2 to move from the first surface 38 to the second surface 39 or from the second surface 39 to the first surface 38.

[0181] In some embodiments, the climbing driving member 29 can be reused as the third driving member 251 to make the swing lever 24 swing synchronously when the side supporting part 2 moves from the first surface 38 to the second surface 39 or from the second surface 39 to the first surface 38, so that the third supporting end 241 is switched to the second position synchronously. In this way, the synchronization between the action of the third supporting end 241 switching to the second position and the action of the side supporting part 2 moving from the first surface 38 to the second surface 39 or from the second surface 39 to the first surface 38 can be improved, so as to further reduce the probability of collision between the third supporting end 241 and the edge of the second surface 39. At the same time, other structures and control schemes for synchronizing the above two actions can no longer be needed, and the structure and control difficulty of the bearing device can be greatly simplified.

[0182] In some embodiments of the present disclosure, as shown in FIG. 1, Figure 7 andFigure 8 As shown, the side support part 2 can have a cleaning state and a lifting state. The climbing driving part 29 can drive the side support part 2 to switch between the cleaning state and the lifting state. The side support part 2 can include a cleaning part 30, at least part of the cleaning part 30 is in contact with the surface to be cleaned to clean the surface to be cleaned when the side support part 2 is in the cleaning state. When the side support part 2 is in the lifting state, the cleaning part 30 can be away from the surface to be cleaned. The surface to be cleaned can be the first surface 38 or the second surface 39.

[0183] At the same time, as shown, Figure 14 The surface to be cleaned can have a first cleaning area A1 and a second cleaning area A2, the first cleaning area A1 can be located at the edge of the surface to be cleaned. And because the side support part 2 is located at the side of the main body part 1, the first cleaning area A1 is an area that the main body part 1 cannot clean, and the second cleaning area A2 is an area that the main body part 1 can clean. Therefore, by providing the cleaning part 30 on the side support part 2 and making the side support part 2 have a cleaning state, the side support part 2 can be used to clean the area that the main body part 1 cannot clean, so as to eliminate the cleaning dead angle.

[0184] As shown, Figure 7 And Figure 8 The side support part 2 can further include a first pressing part 33. The first pressing part 33 can be configured to apply a force to the cleaning part 30 when the side support part 2 is in the cleaning state, so that the cleaning part 30 is in abutment with the surface to be cleaned. In this way, it can be ensured that the cleaning part 30 is in contact with the surface to be cleaned at all times, and the cleaning effect of the cleaning part 30 on the surface to be cleaned is improved.

[0185] The first pressing part 33 can be an elastic element, one end of the first pressing part 33 can be connected with the body part 23, and the other end can be connected with the cleaning part 30; when the cleaning part 30 is in contact with the surface to be cleaned, the first pressing part 33 can elastically deform, so that the first pressing part 33 has a restoring force, and the first pressing part 33 can use the restoring force to make the cleaning part 30 in abutment with the surface to be cleaned. The first pressing part 33 can be a spring, but is not limited thereto, and the first pressing part 33 can also be other elements capable of elastically deforming.

[0186] In some embodiments, the body part 23 can be provided with a first fixing block 34, one end of the first pressing part 33 can be connected with the first fixing block 34, and the other end can be connected with the cleaning part 30, so that the first pressing part 33 can elastically deform after the cleaning part 30 is in contact with the surface to be cleaned.

[0187] The cleaning piece 30 can be provided with a first sliding groove 301 extending along the height direction H of the body part 1, and the first fixed block 34 can be in sliding fit with the first sliding groove 301 to connect the cleaning piece 30 with the body part 23 and limit the movement direction of the cleaning piece 30, so that the cleaning piece 30 can only reciprocate in the height direction H. When the cleaning piece 30 contacts the surface to be cleaned, the cleaning piece 30 can slide relative to the first fixed block 34 to cause the first pressing piece 33 to elastically deform.

[0188] In some embodiments, the cleaning piece 30 can be configured to reciprocate in a third direction Z. Any two of the second direction Y, the third direction Z and the height direction H are perpendicular, and the second direction Y is the direction in which the side support part 2 points to the body part 1. It can be understood that the third direction Z can be the length direction of the carrying device. By reciprocating the cleaning piece 30 in the third direction Z, the cleaning range of the cleaning piece 30 in the third direction Z can be increased, so that the cleaning effect of the cleaning piece 30 can be further improved.

[0189] The cleaning piece 30 can be provided with a second sliding groove 302 extending along the third direction Z, and the second sliding groove 302 can be in communication with the first sliding groove 301. The first fixed block 34 and the second sliding groove 302 can be in sliding fit to limit the movement direction of the cleaning piece 30, so that the cleaning piece 30 can reciprocate in the height direction H and the third direction Z.

[0190] The cleaning piece 30 can be connected with the swing rod 24. When the swing rod 24 rotates relative to the body part 23, the swing rod 24 can have displacement in the third direction Z to drive the cleaning piece 30 to reciprocate in the third direction Z. In this way, the linkage of the swing rod 24 and the cleaning piece 30 can be realized, and it is not necessary to additionally provide other structures to drive the cleaning piece 30 to reciprocate in the third direction Z, so that the structure of the carrying device can be simplified.

[0191] The cleaning piece 30 is provided with a third sliding groove 305 extending along the height direction H. The side support part 2 can further include a second fixed block 35. The second fixed block 35 can be provided on the swing rod 24, and the second fixed block 35 and the third sliding groove 305 can be in sliding fit. In this way, the movement direction of the cleaning piece 30 relative to the swing rod 24 can be limited, so that the cleaning piece 30 can only reciprocate relative to the swing rod 24 in the height direction H to ensure that the swing rod 24 can drive the cleaning piece 30 to move in the third direction Z.

[0192] The side supporting part 2 can further include a second pressing member 36. The second pressing member 36 can be an elastic element, one end of the second pressing member 36 can be connected with the second fixed block 35, and the other end can be connected with the cleaning member 30. When the cleaning member 30 is in contact with the surface to be cleaned, the cleaning member 30 can slide relative to the second fixed block 35, so that the second pressing member 36 is elastically deformed, so that the second pressing member 36 has a restoring force, and the second pressing member 36 can use the restoring force to abut the cleaning member 30 against the surface to be cleaned. The second pressing member 36 can be a spring, but is not limited thereto, and the second pressing member 36 can also be other elements capable of elastically deforming.

[0193] The side supporting part 2 can simultaneously include the first pressing member 33 and the second pressing member 36 to simultaneously apply force to the cleaning member 30 by the first pressing member 33 and the second pressing member 36, so as to further ensure that the cleaning member 30 is in contact with the surface to be cleaned at all times, and further improve the cleaning effect of the cleaning member 30 on the surface to be cleaned.

[0194] The side supporting part 2 can include a plurality of first pressing members 33, a plurality of second pressing members 36, a plurality of first fixed blocks 34, or a plurality of second fixed blocks 35, etc. The specific number of the first pressing member 33, the second pressing member 36, the first fixed block 34, and the second fixed block 35 is not limited in the present disclosure, and can be selected and set according to actual conditions, which are all within the protection scope of the present disclosure.

[0195] In some embodiments, the cleaning member 30 can include a connecting plate 303 and a scraping strip 304. The other end of the first pressing member 33 can be connected with the connecting plate 303, and the first sliding groove 301 can be arranged on the connecting plate 303. The scraping strip 304 can be installed on the side of the connecting plate 303 close to the surface to be cleaned. When the side supporting part 2 is in a cleaning state, the scraping strip 304 is in contact with the surface to be cleaned. Since the connecting plate 303 has higher structural strength than the scraping strip 304, arranging the first sliding groove 301 on the connecting plate 303 can improve the connection strength between the cleaning member 30 and the body part 23. For example, the material of the scraping strip 304 can be soft rubber or felt, but is not limited thereto, and the material of the scraping strip 304 can also be plastic, etc.

[0196] The second sliding groove 302 can also be arranged on the connecting plate 303 to improve the connection strength between the cleaning member 30 and the swing rod 24. Moreover, the first pressing member 33 and the second pressing member 36 can be connected with the connecting plate 303 to improve the connection strength between the first pressing member 33 and the second pressing member 36 and the cleaning member 30.

[0197] In some embodiments, as Figure 14As shown, the bearing device can further comprise a position detector. The position detector can be configured to detect the position of the side support part 2. When the position detector detects that the side support part 2 is in the first cleaning area A1, the side support part 2 is switched from the lifting state to the cleaning state. The first cleaning area A1 can be an area that the main body part 1 cannot clean, but is not limited thereto. In this way, the position detector can be used to accurately determine the timing at which the side support part 2 needs to clean the surface to be cleaned, thereby avoiding the problem of damage to the cleaning element 30 due to the side support part 2 switching to the cleaning state too early, and also avoiding the problem of the side support part 2 being unable to better clean the surface to be cleaned in the first cleaning area A1 due to the side support part 2 switching to the cleaning state too late.

[0198] Further, when the first cleaning area A1 is located at the edge of the surface to be cleaned, the position detector can be configured to detect the relative position between the side support part and the edge of the surface to be cleaned. When the position detector detects that the side support part is located at the edge of the step surface to be cleaned, it can be considered that the side support part is in the first cleaning area, and the side support part is switched from the lifting state to the cleaning state.

[0199] The edge of the surface to be cleaned can have a stop structure. The position detector can be a collision detector, such as a microswitch or the like. The collision detector can be arranged on the side of the side support part 2 away from the main body part 1, and the collision detector is configured to detect the collision between the side support part 2 and the stop structure. When the collision detector detects that the side support part 2 collides with the stop structure, it can be considered that the side support part 2 is in the first cleaning area A1, and the side support part 2 can be switched from the lifting state to the cleaning state. Thus, by arranging the collision detector, the side support part 2 can be more accurately detected whether it reaches the first cleaning area A1, so as to further improve the accuracy of the timing at which the side support part 2 switches to the cleaning state.

[0200] However, the position detector can also be a distance sensor, such as an infrared sensor or the like. The distance sensor can be arranged on the main body part 1 or the side support part 2, so as to detect the distance between the side support part 2 and the stop structure, thereby determining whether the side support part 2 reaches the first cleaning area A1.

[0201] In some embodiments, when the side support part 2 is cleaning the first cleaning area A1, the cleaning element 30 can be used to clean the dirt located in the first cleaning area A1, so as to sweep the dirt to the second cleaning area A2 that can be reached by the main body part 1. At this time, the cleaning device of the main body part 1 or the cleaning device arranged on the bearing structure 11 of the main body part 1 can be used to further clean the dirt, thereby achieving the purpose of cleaning all areas of the surface to be cleaned without dead angles.

[0202] In some embodiments, as shown in FIG. 6, the bearing device can further comprise a cleaning element 30 arranged on the side support part 2. The cleaning element 30 can be arranged on the side of the side support part 2 away from the main body part 1. The cleaning element 30 can be a cleaning brush, a cleaning roller, a cleaning cloth or the like. Figures 1 to 14As shown, the carrying device can include two side support parts 2, which can be respectively located on both sides of the main body part 1 in the second direction Y, that is, the two support parts can be located on both sides of the main body part 1 in the width direction thereof. In this way, the support capacity of the side support part 2 to the carrying device can be further improved, thereby further improving the stability and safety of the carrying device. Moreover, when the side support part 2 has the cleaning piece 30, the edges on both sides of the step 3 can be cleaned by the two side support parts 2 respectively, so that the cleaning range and cleaning effect can be further improved, and the cleaning dead angle can be further eliminated.

[0203] Some embodiments of the present disclosure provide a control method of a carrying device. The control method of the carrying device is used to control the carrying device as described above, such as Figure 15 As shown, the control method of the carrying device can include:

[0204] Step S100, detecting whether the side support part 2 has the first overhanging part 37;

[0205] Step S110, when the side support part 2 has the first overhanging part 37, supporting the first overhanging part 37 by using the first support module 21.

[0206] It should be noted that the specific structure, working method and beneficial effects of the carrying device have been described in detail in the above embodiments of the present disclosure, so in the present embodiment, the specific structure, working method and beneficial effects of the carrying device will not be described again, and can be referred to the specific description in the above embodiments, which are all within the protection scope of the present disclosure.

[0207] In step S110, the first support end 2121 can be driven by the first driving part 211 to move towards the first surface 38, so that the first support rod 212 is supported on the first surface 38. Alternatively, the first support rod 212 is rotated by the first driving part 211 along the first direction X, and the first support end 2121 is rotated to the first surface 38, so that the first support rod 212 is supported on the first surface 38.

[0208] In some embodiments, the control method of the carrying device can further include: detecting whether the first support end 2121 contacts the first surface 38 by using the first detector 213. When the first support end 2121 contacts the first surface 38, the first driving part 211 is controlled to stop providing driving force to the first support end 2121 by using the first controller.

[0209] In some embodiments, the control method of the carrying device can further include: driving the first support end 2121 to move away from the first surface 38 by the first driving part 211, so as to release the support of the first overhanging part 37 by the first support rod 212; or driving the first support rod 212 to rotate in the direction opposite to the first direction X by the first driving part 211, so that the first support end 2121 is away from the first surface 38, and the support of the first overhanging part 37 by the first support rod 212 is released.

[0210] Further, the control method of the carrying device can further include: detecting whether the first support end 2121 moves to a preset position away from the first surface 38 by the second detector 215. When the first support end 2121 moves to the preset position, the first driving part 211 is controlled to stop providing driving force to the first support end 2121 by the second controller.

[0211] Further, when the main body 1 is provided with the second support module 13, as shown in Figure 16 the control method of the carrying device can further include:

[0212] Step S120, detecting whether the main body 1 has a second overhanging part;

[0213] Step S130, when the main body 1 has a second overhanging part, supporting the second overhanging part by the second support module 13.

[0214] In step S120, the second support end can be driven to move towards the second support surface by the second driving part 131, so that the second support rod 132 is supported on the second support surface. Alternatively, the second support rod 132 is driven to rotate in the first direction X by the second driving part 131, and the second support end is rotated to the second support surface, so that the second support rod 132 is supported on the second support surface.

[0215] In some embodiments, the control method of the carrying device can further include: driving the second support end to move away from the second support surface by the second driving part 131, so as to release the support of the second overhanging part by the second support rod 132; or driving the second support rod 132 to rotate in the direction opposite to the first direction X by the second driving part 131, so that the second support end is away from the second support surface, and the support of the second overhanging part by the second support rod 132 is released.

[0216] Some other embodiments of the present disclosure also provide a control method of a carrying device. The control method of the carrying device is used to control the carrying device described above, as shown in Figure 17 the control method of the carrying device can include:

[0217] Step S200, obtaining a cleaning instruction.

[0218] Step S210: The controller issues a cleaning command to the corresponding side support and switches the side support to a cleaning state so that the cleaning component can be used to clean the surface to be cleaned.

[0219] The cleaning instructions may include: cleaning instructions for the side support section, etc.

[0220] It should be noted that the specific structure, working method and beneficial effects of the carrier device have been described in detail in the above embodiments. Therefore, in this embodiment, the specific structure, working method and beneficial effects of the carrier device will not be described again. You can refer to the specific description in the above embodiments, which are all within the protection scope of this disclosure.

[0221] In some embodiments, such as Figure 18 As shown, in step S210, the position detector can detect the position of the side support 2;

[0222] When the position detector detects that the side support is in the first cleaning area A1, the controller controls the side support 2 to switch from the raised state to the cleaning state, so as to use the cleaning component 30 to clean the first cleaning area A1.

[0223] In some embodiments, such as Figure 19 As shown, in step S210, the collision detector detects a collision between the side support 2 and the stop structure. When the collision detector detects a collision between the side support 2 and the stop structure, the side support 2 is in the first clean area A1.

[0224] In some embodiments, the side support 2 can be controlled to move towards the second cleaning area A2, so that the cleaning member 30 sweeps the dirt on the surface to be cleaned from the first cleaning area A1 to the second cleaning area A2, thereby achieving the cleaning of the first cleaning area A1. Furthermore, the second cleaning area A2 can be cleaned using a cleaning device, thereby achieving the purpose of cleaning all areas of the surface to be cleaned without dead angles.

[0225] For example, the first cleaning area A1 can be the two sides of the surface to be cleaned. The side support 2 can be controlled to move to one side edge of the surface to be cleaned, and then the side support 2 is switched to a cleaning state. The side support 2 is controlled to move to the second cleaning area A2, and when the side support 2 reaches the point where the main body 1 can reach the second cleaning area A2, the side support 2 is controlled to switch to a raised state.

[0226] The side support part 2 can be controlled to move to the edge of the other side first cleaning area A1 of the surface to be cleaned, and then the side support part 2 is switched to the cleaning state. The side support part 2 is controlled to move to the second cleaning area A2, and when the side support part 2 reaches the second cleaning area A2, the side support part 2 is controlled to switch to the lifting state. At this time, the second cleaning area A2 can be cleaned by the cleaning device.

[0227] In some embodiments of the present disclosure, a computer readable storage medium is also provided, and at least one program code is stored on the computer readable storage medium. The at least one program code can be loaded and executed by a processor to implement the control method of the bearing device described in the above embodiments.

[0228] The computer program product can adopt a portable compact disc read-only memory (CD-ROM) and include at least one program code, and can be run on a terminal device, such as a personal computer. However, the program product in the present embodiment is not limited to this. In the present embodiment, the computer readable storage medium can be any tangible medium containing or storing the computer program product, which can be used by or in combination with an instruction execution system, device or apparatus.

[0229] The computer program product can be stored in one or more computer readable storage media. The computer readable storage medium can be a readable signal medium or a readable storage medium. The readable storage medium can be, but is not limited to, an electrical, magnetic, optical, electromagnetic, infrared, or semiconductor system, device or apparatus, or any combination thereof.

[0237] The cleaning system provided in this disclosure includes the cleaning device described above, which includes a support device and a cleaning device. The support device may include a main body 1 and a side support 2. The side support 2 includes a first support module 21, which is configured to support the first suspended portion 37 when the side support 2 is located on the second surface 39 and has a first suspended portion 37.

[0238] When the width of the second surface 39 is relatively wide, the side support 2 does not have the first suspended portion 37 when it is located on the second surface 39. The side support 2 can provide support so that the load-bearing device can maintain a stable center of gravity on the second surface 39, and the load-bearing device has higher safety and stability when working on the wider second surface 39.

[0239] When the width of the second surface 39 is narrow, the side support part 2 has the first overhanging part 37 when located on the second surface 39, which causes the center of gravity of the carrying device on the second surface 39 to be unstable, and the first support module 21 can be used to support the first overhanging part 37, so that the center of gravity of the carrying device on the second surface 39 is kept, thereby making the carrying device have higher safety and stability when working on the narrow second surface 39. Therefore, the carrying device can be applied to second surfaces 39 with different widths and have higher safety and stability when working on second surfaces 39 with different widths.

[0240] In addition, since the first support module 21 can support the first overhanging part 37, the carrying device can be applied to first surfaces 38 and second surfaces 39 with different height differences, and can ensure that the carrying device has higher stability when located on the second surface 39 with different height differences from the first surface 38, thereby improving the safety and stability of the carrying device when working on the second surface 39 with different height differences from the first surface 38.
