[0043] The utility model also proposes an automatic cleaning device, referring to Figures 1 to 3 , the automatic cleaning device comprises:

[0044] Main frame 20;

[0045] The secondary frame 10 is disposed on one side of the main frame 20 and is movably connected to the main frame 20;

[0046] A cleaning mechanism 60 is disposed on a side of the sub-frame 10 facing the surface to be cleaned and connected to the sub-frame 10;

[0047] The sub-frame 10 can move relative to the main frame 20 to drive the cleaning mechanism 60 to move closer to or away from the surface to be cleaned.

[0048] In this embodiment, refer to Figures 1 to 3 The main frame 20 can also be used to install at least one of the control module, drive module, dust collection module or other modules of the automatic cleaning device, and the sub-frame 10 can be used to install at least one of the water tank, cleaning mechanism 60 or other components. The cleaning mechanism 60 includes a bracket 61 arranged on the side of the sub-frame 10 facing the surface to be cleaned and a cleaning member 62 arranged on the bracket 61. The cleaning member 62 includes but is not limited to a side brush, a roller brush, a roller, a mop or other components that can be used for cleaning.

[0049] In some embodiments, the cleaning member 62 is a crawler mop, and the bracket 61 includes at least one roller. The crawler mop is wound around the roller and installed on the sub-frame 10 through the bracket 61. A motor or the like can be provided as a power source of the cleaning mechanism 60 to drive the roller to rotate and drive the crawler mop to rotate, thereby cleaning the surface to be cleaned (for example, the ground).

[0050] In some embodiments, the main frame 20 and the secondary frame 10 are movably connected in a direct hinged form, such as an extension portion extending toward the other side of the main frame 20 or the secondary frame 10, and the extension portion is hinged to the other side. Specifically, the extension portion extends from the secondary frame 10 to the main frame 20, and the end of the extension portion is hinged to the main frame 20. The extension portion is provided so that the end of the secondary frame 10 away from the hinge point can be lifted or dropped relative to the hinge point, thereby preventing one end of the secondary frame 10 from rising and the other end from falling during the lifting process.

[0051] In some embodiments, reference Figure 7 , the main frame 20 is slidably connected with the sub-frame 10, the sliding direction of the sub-frame 10 intersects with the surface to be cleaned, the sliding direction of the sub-frame 10 can be perpendicular to the surface to be cleaned, and can also form an acute angle or an obtuse angle with the surface to be cleaned. In this embodiment, a mounting portion 21 extending toward the sub-frame 10 can be provided on the main frame 20, and a mounting position for mounting the sub-frame 10 is formed between the two mounting portions 21, and a sliding module 22 is provided between the mounting portion 21 and the sub-frame 10, and the sliding module 22 is used to connect the mounting portion 21 and the sub-frame 10, and the sliding module 22 slides on the mounting portion 21 to achieve the sliding connection between the sub-frame 10 and the main frame 20. For example, the sliding module includes a slide groove provided on the mounting portion 21, and a sliding block adapted to the slide groove, the sliding block slides in the slide groove, and the sliding block is also fixedly connected to the sub-frame 10. In addition, any other form that can achieve sliding can also be used, which is not limited here.

[0052] In some embodiments, during the cleaning process of the automatic cleaning device, the main frame 20 is located at the front end of the cleaning route, and the sub-frame 10 and the cleaning mechanism 60 are located at the rear end of the cleaning route. When the protrusion of the surface to be cleaned touches the cleaning mechanism 60, a thrust toward the rear of the cleaning path is applied to the cleaning mechanism 60. Therefore, the sliding module 22 can be tilted so that the cleaning mechanism 60 moves obliquely upward relative to the frame when it is lifted, so that the resistance when the sub-frame 10 is lifted is smaller.

[0053] In the process of cleaning the surface to be cleaned, if the cleaning mechanism 60 cannot float adaptively, when the cleaning mechanism 60 encounters a protrusion on the surface to be cleaned, it will not be able to clean properly due to resistance, or it will cause uneven water stains; or, when the cleaning mechanism 60 encounters a concave part of the surface to be cleaned, it will not be able to clean the concave part well, or the water stains will gather in the concave part.

[0054] In addition to the hinged and sliding connection methods mentioned above, the main frame 20 and the sub-frame 10 can also be connected by referring to Figure 8The main frame 20 and the sub-frame 10 can also be connected through an elastic member 31. The elastic member 31 can be a spring, an air spring, a spring sheet, etc. One end of the elastic member 31 is connected to the main frame 20 and the other end is connected to the sub-frame 10. When encountering the above-mentioned protrusion, the cleaning mechanism 60 is pushed to swing up.

[0055] The utility model provides a main frame 20 and a sub-frame 10 that are connected to each other and can move relative to each other, and the cleaning mechanism 60 is arranged on the sub-frame 10. When the surface to be cleaned encounters unevenness, the cleaning mechanism 60 will float adaptively by itself or passively float with the sub-frame 10, so as to avoid that the protrusions excessively squeeze the cleaning mechanism 60 and leave uneven water stains on the ground, or the concave parts cannot be effectively cleaned and the water stains gather in the concave parts.

[0056] In some embodiments, reference Figures 2 to 3 , Figure 6 , the automatic cleaning device also includes a connecting rod 30, one end of which is connected to the secondary frame 10 and the other end is connected to the main frame 20. In this embodiment, a single connecting rod 30 can also be set so that one end of the connecting rod 30 is hinged to the main frame 20 and the other end is hinged to the secondary frame 10, so as to realize the floating setting of the secondary frame 10. It is also possible to use multiple connecting rods 30 to connect the main frame 20 and the secondary frame 10, so that the main frame 20 and the secondary frame 10 and the multiple connecting rods 30 form a multi-link mechanism. When lifting, both ends of the secondary frame 10 need to be lifted at the same time. Therefore, in this embodiment, the connecting rod mechanism can be further optimized. Specifically, two parallel connecting rods 30 are set, and the lines connecting the hinges of the two connecting rods 30 and the main frame 20 are perpendicular to the ground, and the lines connecting the hinges of the two connecting rods 30 and the secondary frame 10 are perpendicular to the ground, so that the connecting rod 30 and the main frame 20 and the secondary frame 10 form a parallelogram connecting rod mechanism, and the secondary frame 10 always remains flat during the lifting process. The sewage tank 50 and / or the clean water tank 80 moving with the subframe 10 will not tilt with the lifting of the subframe 10, thus preventing the liquid in the tank from spilling. In order to keep the subframe 10 balanced and to simultaneously bear force at both ends, connecting rods 30 may be provided at both ends.

[0057] In some embodiments, reference Figure 1, the automatic cleaning device also includes a driving mechanism 70 for driving the sub-frame 10 to approach or move away from the surface to be cleaned. In the above embodiment, the sub-frame 10 is passively lifted by the bulging ground. In this embodiment, a driving mechanism 70 can be provided to drive the sub-frame 10 to actively rise and fall. Specifically, an electromagnetic push rod 76 can be provided with one end connected (for example, hinged) to the main frame 20 and the other end connected (for example, hinged) to the sub-frame 10. The extension and contraction of the electromagnetic push rod 76 allows the sub-frame 10 to move relative to the main frame 20. A reset member 77 (for example, a torsion spring) can also be provided at the connection (for example, a hinge) between the main frame 20 and the sub-frame 10, so that the torsion of the torsion spring buffers the thrust of the electromagnetic push rod when it is pushed out. In addition to using the above-mentioned electromagnetic push rod as the driving force for driving the sub-frame 10 to lift, a motor and a corresponding transmission mechanism can also be provided to connect with the connecting rod 30 or the sub-frame 10 to drive the swing of the connecting rod 30, or drive the sub-frame 10 to move. For example, a motor is arranged on the mounting portion, a gear is arranged on the motor, and a rack matched with the gear is arranged on the sub-frame 10 , and the rotation of the motor drives the sub-frame 10 to slide.

[0058] In some embodiments, reference Figures 4 to 5 , the driving mechanism 70 comprises:

[0059] A motor 71 is arranged on the main frame 20;

[0060] A traction wheel 72 connected to the output shaft of the motor 71;

[0061] One end of the rope 73 is wound around the traction wheel 72 and the other end is connected to the secondary frame 10 .

[0062] In this embodiment, the rope 73 can be directly fixed on the sub-frame 10, or can be fixed on the connecting rod 30 to achieve connection with the sub-frame 10. The motor 71, the traction wheel 72 and the rope 73 constitute a winch to achieve traction of the sub-frame 10.

[0063] In some embodiments, reference Figure 1 The automatic cleaning device further comprises a mounting plate 11 fixedly mounted above the sub-frame 10, and a mounting groove 13 is arranged on the mounting plate 11, and one end of the rope 73 away from the traction wheel 72 is embedded in the mounting groove 13 and connected to the sub-frame 10; in this embodiment, two ropes 73 are arranged, one end of the two ropes 73 is wound around the traction wheel 72, and the other end is respectively fixed on both sides of the sub-frame 10, so that the forces on the left and right sides of the sub-frame 10 are balanced when the sub-frame 10 is raised or lowered. The mounting groove 13 is arranged on the mounting plate 11 to limit the rope 73 from being retracted and released in the mounting groove 13, and plays a role in positioning.

[0064] In some embodiments, a guide tube 74 is fixedly disposed in the mounting groove 13, and one end of the rope 73 away from the traction wheel 72 passes through the guide tube 74 and is connected to the sub-frame 10. The provision of the guide tube 74 further constrains the rope 73, preventing the rope 73 from being separated from the notch of the mounting groove 13 and interfering with other components. The rope 73, the guide tube 74 and the mounting groove 13 may be made of a material with a self-lubricating effect, or a lubricant may be provided inside the rope 73, the guide tube 74 and the mounting groove 13 to reduce the friction of the rope 73.

[0065] In some embodiments, reference Figure 2 , the automatic cleaning device also includes:

[0066] A guide sleeve 12, arranged on the secondary frame 10;

[0067] The guide post 75 is arranged at one end of the rope 73 away from the traction wheel 72, and the guide post 75 is slidably connected in the guide sleeve 12. One end of the guide sleeve 12 is closed, and the guide post 75 includes a sliding portion 751 and a clamping portion 752. During the sliding process of the guide post 75 in the guide sleeve 12, the sliding portion 751 can slide out of the closed end of the guide sleeve 12, and the clamping portion 752 cannot slide out of the closed end of the guide sleeve 12. By setting the guide sleeve 12 and the guide post 75, a certain amount of retraction margin is provided during the retraction and release of the rope 73, so as to avoid the rope 73 not being retracted into place and the sub-frame 10 being still in a lifted state, or the rope 73 being retracted too much and causing the sub-frame 10 to be lifted too high and touch the components above it; by limiting the clamping portion 752 in the guide sleeve 12 and preventing it from sliding out, the rope 73 is prevented from being over-tightened by the traction wheel 72, thereby controlling the range of motion of the sub-frame 10.

[0068] In some embodiments, reference Figure 8 , the automatic cleaning device also includes:

[0069] A sewage tank assembly 50 connected to the subframe 10; and / or,

[0070] The scraper groove 40 abuts against the cleaning mechanism 60; and / or,

[0072] In this embodiment, at least one of the sewage tank assembly 50, the wiper trough 40 and the clean water tank assembly 80 can be arranged on the sub-frame 10. By arranging the sewage tank assembly 50, the wiper trough 40 and the clean water tank assembly 80 on the sub-frame 10, the three can be raised and lowered together with the sub-frame 10, avoiding the need to set up a complex and long waterway to connect the cleaning mechanism 60 and the sewage tank assembly 50, the wiper trough 40 or the clean water tank assembly 80, so that the internal structure of the automatic cleaning device is more compact.

[0073] In some embodiments, the sewage tank body of the sewage tank assembly 50 is accommodated in the accommodating cavity 14 of the sub-frame 10, and the clean water tank body of the clean water tank assembly 80 is arranged outside the accommodating cavity 14 of the sub-frame 10, and the scraper groove 40 abuts against the cleaning member 62 of the cleaning mechanism 60 so that during the rotation of the cleaning member 62, the dirt on the cleaning member 62 can be scraped into the scraper groove 40.
