Description

Technical Field

[0001] The present application relates to the technical field of household electrical appliances, and in particular to a guiding mechanism of a cleaning system and a cleaning system. Background Art

[0002] As people's living standards improve, the demand for intelligent household appliances is getting higher and higher. The sweeping robot of the cleaning system can automatically clean the floor in the room. When the sweeping robot completes the cleaning task or is low on power, it will automatically return to the base station of the cleaning system to charge. Since there is a certain height difference between the charging position in the base station and the ground, a guiding mechanism is usually set at the entrance of the base station so that the sweeping robot can smoothly enter the base station along the guiding mechanism.

[0003] The guiding mechanism is provided with a guiding surface, and the sweeping machine can move along the guiding surface to the charging position in the base station. If the slope of the guiding surface is large, the sweeping machine is prone to slipping on the slope when it is on the pile, resulting in failure of the pile and a lower success rate of recharging after the pile is on, affecting the user experience. However, if the slope of the guiding surface is set to be smaller, the guiding mechanism will occupy a larger space.

[0004] How to prevent the sweeper from slipping when it is on the pile, improve the success rate of pile recharging and user experience, and at the same time reduce the space occupied by the guiding mechanism is a technical problem that technical personnel in this field urgently need to solve.

In addition, since the guide mechanism can achieve an anti-skid effect on the walking wheels during the pile mounting process of the sweeper, the slope requirement of the guide surface can be reduced, thereby reducing the overall length of the guide surface, thereby facilitating miniaturization and reducing floor space.

[0041] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0042] The present application embodiment provides a guiding mechanism of a cleaning system and a cleaning system, wherein: Figure 1 As shown, the cleaning system includes a base station 30, a sweeping machine 20 and a guiding mechanism 10. The sweeping machine 20 is a component that can be used to clean the floor. The base station 30 can be used to charge the sweeping machine 20. The guiding mechanism 10 is arranged at the entrance 301 of the base station 30. Specifically, it can be integrated with the base station 30, or it can be directly or indirectly fixed to the base station 30. The guiding mechanism 10 is used to guide the sweeping machine 20 to enter the base station 30.

[0043] Specifically, when the sweeping machine 20 completes the cleaning operation or is low on power, it will automatically return to the base station 30 along the guide mechanism 10. Figure 2 As shown, the guide mechanism 10 includes a pad body 1, and a guide surface 11 is provided at the front end of the pad body 1. The guide surface 11 is a sloped surface, and the front end height of the guide surface 11 is lower than the rear end height, which is used to provide guidance for the sweeping machine 20, so that the sweeping machine 20 can smoothly enter the base station 30 from the ground along the guide surface 11. The pad body 1 can also be provided with a guide surface located at the rear side of the guide surface 11, and the sweeping machine 20 entering the base station 30 along the guide surface 11 can move to a preset position along the guide surface.

[0044] It should be noted that, for the convenience of description, in this article, the directions or positional relationships such as "front", "rear", "left", "right", "inside", and "outside" are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the components referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present application. Specifically, "front" refers to the side away from the base station 30, and "rear" refers to the side facing the base station 30. The sweeper 20 can move from front to back along the guide surface 11 of the guide mechanism 10 into the base station 30, and the left-right direction is perpendicular to the front-to-back direction. "Inside" refers to the side toward the middle position along the left-right direction, and "outside" refers to the side on both sides along the left-right direction.

[0045] It is not difficult to understand that if the inclination angle of the guide surface 11 (specifically the angle between the guide surface 11 and the ground) is larger, the length of the guide surface 11 in the front-to-back direction is smaller, and the occupied space is smaller. However, this setting makes it easy for the walking wheels 5 to slip when the sweeping machine 20 passes through the guide surface 11, resulting in a low success rate of the sweeping machine 20 getting on the pile, affecting the user experience. If the inclination angle of the guide surface 11 is set to be smaller and the slope is gentler, it is convenient for the sweeping machine 20 to pass through the guide surface 11 smoothly. However, the smaller the inclination angle, the longer the length of the guide surface 11 in the front-to-back direction, and the larger the space occupied, which is not conducive to miniaturization.

[0046] The guide mechanism 10 of the cleaning system provided in the embodiment of the present application also includes an anti-skid component. When the sweeper 20 moves to the guide mechanism 10, it can cooperate with the anti-skid component to reduce the slipping of the walking wheels 5 of the sweeper 20 on the guide surface 11, which is conducive to the sweeper 20 smoothly entering the base station 30 along the guide surface 11. At the same time, it can also reduce the length of the guide mechanism 10 and reduce the occupied space.

[0047] Specifically, Figure 2 As shown, the anti-skid component includes a first anti-skid portion 2 and a second anti-skid portion 3, wherein the first anti-skid portion 2 is used to provide power to the sweeping machine 20 when the walking wheel 5 of the sweeping machine 20 has not reached the guide surface 11, and assists the sweeping machine 20 to move backward until the walking wheel 5 moves to the guide surface 11, and the second anti-skid portion 3 can increase the friction between the walking wheel 5 and the guide surface 11 after the walking wheel 5 moves to the guide surface 11, thereby preventing the walking wheel 5 from slipping on the guide surface 11, and ensuring that the sweeping machine 20 can smoothly move from the ground along the guide surface 11 to the base station 30.

[0048] like Figure 2 and Figure 3As shown, the first anti-slip portion 2 is roughly located in the middle area on the left and right sides of the guide surface 11. The middle area of ​​the guide surface 11 is arched upward to form a convex surface, and at least part of the first protrusion 21 is arranged on the convex surface, so that the height of the first protrusion 21 located in the middle area is higher than the height of the second protrusion 31 located in the two side areas, that is, the upper end surface of the first anti-slip portion 2 located in the middle area protrudes upward from the upper end surface of the second anti-slip portion 3.

[0049] The bottom of the sweeping machine 20 is provided with a running wheel 5 and a cleaning part 6, wherein the running wheel 5 rotates to drive the sweeping machine 20 to move, and the cleaning part 6 includes two cleaning members 61, which can be a cleaning brush, a mop, etc. The two cleaning members 61 rotate in opposite directions, such as Figure 2 and Figure 3 As shown, the cleaning member 61 on the left rotates clockwise, and the cleaning member 61 on the right rotates counterclockwise. The two cleaning members 61 rotate simultaneously to bring the foreign matter they come into contact with into the space between the two cleaning members 61 and collect it, so as to clean the foreign matter on the ground. To ensure the cleaning ability and cleaning range, the outer edge of the cleaning member 61 extends out of the edge of the sweeper 20, so as to clean the sanitary blind corners.

[0050] Since the outer edge of the cleaning portion 6 extends out, when the cleaning portion 6 moves to the guide surface 11, the running wheel 5 is still moving on the ground and has not reached the guide surface 11. During the rotation process, the cleaning member 61 can interact with the first protrusion 21 located in the middle area of ​​the guide surface 11.

[0051] When the cleaning member 61 rotates, the inner side of the cleaning member 61 can contact and cooperate with the first protrusion 21 located in the middle area, which can increase the friction force between the cleaning member 61 and the guide surface 11 and reduce the slipping of the cleaning member 61 on the guide surface 11.

[0052] Furthermore, since the inner part of the cleaning member 61 rotates toward the front side when the cleaning member 61 rotates, the first protrusion 21 can provide resistances F1 and F2 to the rotation of the inner parts of the two cleaning members 61, respectively. Figure 3 As shown, the components f1 and f2 of the resistance F1 and F2 in the left and right directions are equal in magnitude and opposite in direction, therefore, the cleaning portion 6 continues to move backward without being deflected, while the components f3 and f4 of the resistance F1 and F2 in the front and rear directions are equal in magnitude and both are directed backward, which is the same as the moving direction of the sweeper 20 entering the base station 30, thereby forming a power F (F=f3+f4) for the sweeper 20 to enter the base station 30, and assisting the walking wheel 5 to move from the ground to the guide surface 11, thereby preventing the walking wheel 5 from slipping when the ground does not reach the guide surface 11 due to the smooth ground, thereby ensuring that the sweeper 20 can move smoothly to the guide surface 11.

[0053] It is easy to understand that the inner sides of the two cleaning members 61 are arranged close to each other, and the outer side of the cleaning member 61 refers to a side away from the other cleaning member 61 .

[0054] That is to say, the upper end surface of the first anti-slip portion 2 located in the middle area protrudes upward from the upper end surface of the second anti-slip portion 3, and can cooperate with the cleaning member 61 through the first protrusion. While preventing the cleaning member 61 from slipping and the walking wheel 20 from slipping on the ground, the cleaning member 61 can also provide power for moving backward to the sweeper 20, thereby ensuring that the sweeper 20 can smoothly reach the guide surface 11 from the ground.

[0055] In this embodiment, it can be as follows Figure 3 As shown, the first protrusion 21 is located in the middle position of the left-right direction of the guide surface 11, and is only arranged corresponding to the inner side of the cleaning member 61, that is, the outer side of the cleaning member 61 does not act on the first protrusion 21, so as to avoid generating resistance for the sweeper 20 to move backward. Alternatively, the first anti-slip portion 2 can be arranged so that the height of the inner side is higher than the height of the outer side, so that the force between the inner side of the cleaning member 61 and the first protrusion 21 is greater than the force between the outer side of the cleaning member 61 and the first protrusion 21, thereby ensuring that the total force between the first anti-slip portion 2 and the cleaning member 61 is backward.

[0056] Of course, in this embodiment, the middle position of the guide surface 11 may not be arched upwards, and at the same position in the front-to-back direction, the height of the first protrusion 21 is higher than the height of the second protrusion 31. By increasing the height of the first protrusion 21, the upper end surface of the first protrusion 21 can be raised above the upper end surface of the second protrusion 31, ensuring that the first protrusion 21 can cooperate with the cleaning member 61 to achieve an anti-slip effect while also providing power for the sweeper 20 to move backward. By forming a raised surface in the middle area of ​​the guide surface 11, the upper end surface of the first anti-slip portion 2 can be raised above the upper end surface of the second anti-slip portion 3, which can simplify the manufacturing process and reduce costs.

[0057] Alternatively, the height of the upper end surface of the first protrusion 21 may be the same as the height of the upper end surface of the second protrusion 31, and the upper end surface of the first anti-slip portion 2 may protrude upward from the upper end surface of the second anti-slip portion 3, and the height of the first protrusion 21 may be higher than the height of the second protrusion 31. This ensures that the force between the first protrusion 21 and the cleaning member 61 is maintained, which is beneficial for the sweeper 20 to move to the guide surface 11.

[0058] like Figure 2 and Figure 3As shown, the first anti-slip portion 2 includes two rows of protrusions, which are arranged in parallel along the left-right direction, and the first protrusions 21 of the two rows of protrusions are symmetrically arranged about the center plane, wherein the center plane is parallel to the front-to-back direction and perpendicular to the left-to-right direction of the guide surface 11, and the center plane is approximately located in the middle position of the left-to-right direction of the guide surface 11. Of course, the first protrusions 21 can also be arranged in only one row, which can be arranged according to the actual situation and space arrangement. The two rows of protrusions are respectively arranged corresponding to the two cleaning members 61, and the first protrusions 21 of the two rows of protrusions are symmetrically arranged, so that the acting forces between the two cleaning members 61 and the first protrusions 21 are the same, thereby preventing the sweeper 20 from running off.

[0059] like Figure 2 and Figure 3 As shown, the first protrusions 21 are strip-shaped protrusions, and the first protrusions 21 are arranged in parallel along the front-to-back direction, and at least part of the first protrusions 21 located at the front side are arranged obliquely, and the inner end of the inclined first protrusions 21 is arranged backward and the outer end is arranged forward. In other words, the preset angle of the first protrusions 21 is less than 90°, and the preset angle refers to the angle between the length direction of the first protrusions 21 and the front-to-back direction.

[0060] When two rows of protrusions are arranged at intervals (such as Figure 2 , Figure 3 and Figure 5 As shown in the figure, the first protrusions 21 corresponding to the two rows of protrusions are arranged in an eight-shaped structure, and the first protrusions 21 located on the front side are distributed like cat whiskers. When the inner ends of the first protrusions 21 corresponding to the two rows of protrusions are connected, a V-shaped structure can be formed.

[0061] Of course, in this embodiment, each first protrusion 21 can also be set as a block protrusion, and each first protrusion 21 can be set at a position corresponding to the inner side of the cleaning member 61, or the first protrusion 21 can be set as a strip protrusion, and each strip protrusion is arranged along the left and right direction, that is, the preset angle is 90°.

[0062] When the first protrusion 21 is configured as a strip-shaped protrusion and the first protrusion 21 located at the front side is configured to be inclined, the contact area between the first protrusion 21 and the inner side of the cleaning member 61 can be increased, the resistance (F1, F2) to the cleaning member 61 can be increased, and the power F can be increased. The lengths of the first protrusions 21 can be the same or different, and are not specifically limited here.

[0063] like Figure 2 and Figure 5As shown, there are two groups of second anti-slip parts 3, and the two groups of second anti-slip parts 3 are respectively arranged on the left and right sides of the guide surface 11, and the first anti-slip part 2 is located between the two groups of second anti-slip parts 3. The sweeper 20 is provided with two rows of running wheels 5. After the sweeper 20 moves to the guide surface 11, the two rows of running wheels 5 correspond to the two groups of second anti-slip parts 3 respectively.

[0064] The second anti-slip portion 3 includes a plurality of second protrusions 31 spaced apart from each other. When the sweeping machine 20 moves along the guide surface 11, the second protrusions 31 can increase the friction between the running wheels 5 and the guide surface 11, thereby preventing the running wheels 5 from slipping on the guide surface 11, thereby ensuring that the sweeping machine 20 can smoothly move along the guide surface 11 to the base station 30.

[0065] Specifically, there is no limitation on the specific structure and arrangement of the second protrusion 31. For example, the second protrusion 31 may be as follows: Figure 5 The strip-shaped protrusions shown, the length of each second protrusion 31 is set along the left-right direction, that is, perpendicular to the front-to-back direction, or each second protrusion 31 can be set obliquely, that is, the length direction of the second protrusion 31 forms a preset angle with the front-to-back direction, or the second protrusion 31 can be set as a plurality of block-shaped protrusions arranged at intervals, or some of the second protrusions 31 can be strip-shaped protrusions, and some of the second protrusions 31 can be block-shaped protrusions. When the second protrusions 31 are set as strip-shaped protrusions, the overall structure and molding process can be simplified. Moreover, when each second protrusion 31 is a strip-shaped protrusion, the length of each second protrusion 31 can be the same or different, and no specific restrictions are made here.

[0066] The cross-section of the first protrusion 21 and the second protrusion 31 can be a triangular structure or a trapezoidal structure. Taking the first protrusion 21 as an example, the front side surface of the first protrusion 21 is an inclined surface, and the rear side surface can be an inclined surface or a vertical surface, wherein the inclined surface means that the inclination angle (the angle between the surface of the first protrusion 21 and the guide surface 11) is less than 90°, and the vertical surface means that the angle between the surface of the first protrusion 21 and the guide surface 11 is 90°. The inclination angle of the front side surface is smaller than the inclination angle of the rear side surface, that is, the slope of the front side surface is smaller, and the slope of the rear side surface is larger.

[0067] For the first protrusion 21, the inner side of the cleaning member 61 rotates forward and acts on the rear surface of the first protrusion 21. Since the slope of the rear surface is large, the resistance between the cleaning member 61 and the cleaning member 61 is larger, resulting in a larger force F, which is conducive to driving the sweeper 20 to move backward. If the outer side of the cleaning member 61 acts on the first protrusion 21, it acts on the front wall of the first protrusion 21, and the resistance is relatively small. For the second protrusion 31, the running wheel 5 moves backward along the front surface of the second protrusion 31. Since the slope of the front surface is small, the resistance to the backward movement of the running wheel 5 is small, and since the slope of the rear surface is large, the resistance to the forward movement of the running wheel 5 along the guide surface 11 after passing the second protrusion 31 is large, thereby ensuring a better anti-slip effect.

[0068] Of course, in this embodiment, the cross-sections of the first protrusions 21 may be the same or different, and similarly, the cross-sections of the second protrusions 31 may be the same or different.

[0069] The front side surface or the rear side surface of the first protrusion 21 can also be set as an arcuate surface. Similarly, the front side surface or the rear side surface of the second protrusion 31 can also be set as an arcuate surface. When both side surfaces of the first protrusion 21 and both side surfaces of the second protrusion 31 are set as planar structures (specifically, they can be inclined surfaces or vertical surfaces), the processing technology can be simplified.

[0070] When the first protrusion 21 drives the sweeper 20 to move backward through the cleaning portion 6 until the travel wheel 5 reaches the guide surface 11, the travel wheel 5 may slip when reaching the edge of the guide surface 11 and entering the guide surface 11 due to the smooth ground. Figure 2 , Figure 4 and Figure 5 As shown, the anti-skid assembly also includes an anti-skid tooth portion 4 arranged on the guide surface 11, and the anti-skid tooth portion 4 can interact with the running wheel 5 to ensure that the running wheel 5 can smoothly enter the guide surface 11 when it reaches the front end edge of the guide surface 11 from the ground.

[0071] Specifically, the structure of the tread portion 51 of the running wheel 5 of the sweeper 20 is as follows: Figure 6 As shown, the tread portion 51 includes two rows of pattern portions 52 arranged in parallel, each row of pattern portions 52 includes a plurality of pattern blocks 53 arranged along the circumference of the running wheel 5, and a pattern groove 54 is formed between two adjacent pattern blocks 53. The pattern blocks 53 of the two rows of pattern portions 52 are staggered along the circumference, that is, a pattern block 53 is arranged at a position corresponding to a position of the other row of pattern portions 52, so that the stability of the running wheel 5 during walking can be ensured.

[0072] The width of the surface of the driving wheel 5 in its axial direction (i.e., the left - right direction) is the tread width W. The axial width of the tread block 53 in the axial direction of the driving wheel 5 is W1, and the circumferential length of the tread block 53 in the circumferential direction of the driving wheel 5 is L1. A tread groove 54 is formed between two adjacent tread blocks 53 in the same row of the tread portion 52, and the distance between the two side walls of the tread groove 54 (i.e., the distance between two adjacent tread blocks 53) is S1.

[0073] As Figure 5 and Figure 7 shown, the anti - slip tooth portion 4 includes a plurality of tooth structures 41 arranged along the front - end edge of the guiding surface 11. Each tooth structure 41 is arranged at intervals along the extending direction (left - right direction) of the front - side edge of the guiding surface 11, that is, the arrangement direction of each tooth structure 41 is perpendicular to the moving direction (i.e., the front - back direction) of the sweeper 20, and the front - end edge of the guiding surface 11 forms a structure similar to a saw - tooth shape.

[0074] The top width of the tooth structure 41 along the extending direction of the front - side edge of the guiding surface 11 is W2, the length of the tooth structure 41 in the front - back direction is L2, a tooth groove 42 is formed between two adjacent tooth structures 41, and the distance between the two side walls at the open end of the tooth groove 42 (i.e., the distance between the tops of two adjacent tooth structures 41) is S2.

[0075] The above parameters satisfy L2 < S1, and W2 < W1 < S2 < W. The length L2 of the tooth structure 41 is smaller than the distance S1 between two adjacent tread blocks 53, and the top width W2 of the tooth structure 41 is less than the axial width W1 of the tread block 53. With such a setting, the tooth structure 41 can be inserted into the tread groove 54. At the same time, the axial width W1 of the tread block 53 is less than the distance S2 between the tops of two adjacent tooth structures 41, so that one row of the tread portion 52 can move along the tooth groove 42. And, the distance S2 between the tops of two adjacent tooth structures 41 is less than the tread width W of the driving wheel 5. In this way, it can be avoided that the driving wheel 5 directly moves to the tooth groove 42 without cooperating with the tooth structure 41, resulting in the anti - slip tooth portion 4 being unable to play the role of anti - slipping, and the driving wheel 5 may slip at the tooth groove 42.

[0076] Specifically, there is no limitation on the specific values of the above parameters. For example, the tread width is 15 mm, the axial width W1 of the tread block 53 is 7 mm, the circumferential length L1 of the tread block 53 is 7.3 mm, the distance S1 between two adjacent tread blocks 53 is 3.74, the top width W2 of the tooth structure 41 is 3.5, the length L2 of the tooth structure 41 is 1.73, and the distance S2 between the tops of two adjacent tooth structures 41 is 8.8 mm. The specific values of the parameters can be set according to the actual situation.

[0077] When the sweeper 20 returns to the base station 30 and the driving wheel 5 moves to the anti - slip tooth portion 4, as Figure 8 As shown, there are three positions between the tread portion 51 and the tooth structure 41:

[0078] In the first case, one row of patterned portions 52 moves along the tooth grooves 42, and the patterned grooves 54 between the two patterned blocks 53 of the other row of patterned portions 52 just directly cooperate with the tooth structure 41. At this time, the tooth structure 41 is located in the patterned grooves 54 and abuts against the side walls of the patterned grooves 54 (i.e., the side walls of the patterned blocks 53), thereby preventing the running wheel 5 from idling and slipping. As the running wheel 5 rotates, it can pass through the anti-skid toothed portion 4 and move to the guide surface 11, thereby driving the sweeper 20 to move backward along the guide surface 11.

[0079] In the second case, one row of patterned portions 52 moves along the tooth grooves 42, and the surface of the patterned blocks 53 of the other row of patterned portions 52 first contacts the tooth structure 41, which may cause slippage, that is, the surface of the patterned blocks 53 rotates along the tooth structure 41, but as the travel wheel 5 rotates, when the patterned block 53 in contact with the tooth structure 41 rotates to be separated from the tooth structure 41, the patterned grooves 54 rotate to the tooth structure 41, and the tooth structure 41 can just fit into the patterned grooves 54, and the anti-slip effect is achieved by the abutment with the side walls of the patterned blocks 53, and then the travel wheel 5 continues to rotate, and can pass through the anti-slip tooth portion 4 and move to the guide surface 11, thereby driving the sweeper 20 to move backward along the guide surface 11;

[0080] In the third case, the tooth structure 41 just corresponds to two groups of pattern parts 51 at the same time. When the tooth structure 41 partially contacts the surface of the pattern block 53 of one row of pattern parts 52, and partially corresponds to the pattern groove 54 of another row of pattern parts 52 (neither contacts nor gets stuck in the first groove), the tooth structure 41 only partially abuts against the surface of a pattern block 53 of the running wheel 5, and the contact area is small. Since the running wheel 5 is made of soft rubber, the tooth structure 41 squeezes the pattern block 53 to produce extrusion pits on the surface of the pattern block 53, thereby playing an anti-slip role, so that the running wheel 5 rotates and passes through the anti-slip tooth part 4 and moves to the guide surface 11, thereby driving the sweeper 20 to move backward along the guide surface 11.

[0081] It can be seen that the anti-skid tooth portion 4 is provided at the front end edge of the guide surface 11, which can provide assistance when the running wheel 5 moves from the ground to the guide surface 11, ensuring that the running wheel 5 can smoothly pass through the anti-skid tooth portion 4 and enter the guide surface 11.

[0082] When the running wheel 5 moves to the guide surface 11 , it can cooperate with the second anti-slip portion 3 provided on the guide surface 11 to ensure that the running wheel 5 can smoothly move from front to back along the guide surface 11 into the base station 30 .

[0083] like Figure 5As shown, a tooth structure 41 is provided at the front edge of the guide surface 11 and the position corresponding to the second anti-slip portion 3, while no tooth structure 41 is provided between the two groups of second anti-slip portions 3 in the left and right directions. This arrangement can simplify the overall structure and reduce costs.

[0084] In addition, since the surfaces of the walking wheel 5 and the cleaning member 61 have a certain elasticity, the first protrusion 21, the second protrusion 31 and the tooth structure 41 can increase the friction coefficient at the corresponding position of the guide surface 11. When the cleaning member 61 moves to the middle area of ​​the guide surface 11, due to the setting of the first protrusion 21, the surface of the cleaning member 61 can be deformed to a certain extent, thereby improving the anti-slip property. Similarly, when the walking wheel 5 moves to the tooth structure 41 or the second protrusion 31, the tread portion 51 of the walking wheel 5 can be deformed to a certain extent, thereby improving the anti-slip property.

[0085] The guiding mechanism 10 provided in the present embodiment is provided with a first anti-skid portion 2, an anti-skid tooth portion 4 and a second anti-skid portion 3 on the guiding surface 11, so as to cooperate with the cleaning portion 6 and the walking wheel 5 of the sweeping machine 20 at different stages, so that the sweeping machine 20 can be smoothly moved from the ground to the guiding surface 11, and move backward along the guiding surface 11 to the base station 30. While being able to improve the success rate of pile driving, it is also possible to reduce the overall length of the guiding surface 11 and the length of the guiding mechanism 10 extending out of the base station 30 (such as 160 mm). The shorter the extended length is, the smaller the overall footprint of the cleaning system can be.

[0086] The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
